Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Ett hållbart och acceptabelt pensionssystem måste utformas utifrån personliga förutsättningar och förhållanden i arbetslivet, så att fler klarar att arbeta i högre ålder. Att enbart genom ekonomiska åtgärder höja pensionsåldern är inte långsiktigt hållbart, skriver 54 forskare.DEBATT | PENSIONForskning visar att cirka var fjärde har en diagnos eller skada orsakad av sitt arbete. Detta gör arbetsorsakad sjukdom och skada till ett betydelsefullt folkhälsoproblem. Att då enbart genom ekonomiska åtgärder höja pensionsåldern för samtliga (yrkes)grupper utifrån deras kronologiska ålder är inte långsiktigt hållbart när individers biologiska ålder är så olika bland annat till följd av arbetslivet. Detta är en demokratifråga. Forskning om äldre i arbetslivet och hållbart arbete visar att man då främst flyttar individer från pensionssystemet till sjukförsäkringssystemet och ökar klyftorna i samhället.Debatt Det här är en argumenterande text med syfte att påverka. Åsikterna som uttrycks är skribentens egna.Vi är 54 forskare som nu gemensamt har skrivit denna debattartikel. Anledningen är att vi är oroade över att cirka var fjärde blir sjuk av sitt arbete samtidigt som man i det förslag som ligger om att senarelägga ålderspensionen i princip utgår ifrån att arbetskraftsdeltagande enbart styrs av ekonomin. Vi vill trycka på betydelsen av åtgärder i arbetslivet för att komma tillrätta med ohälsan, det vill säga inte enbart ekonomiska restriktioner som tvingar folk som inte kan, vill och orkar att stanna kvar i arbetslivet till en högre kronologisk ålder.Pensionssystemet bygger på att vi ska arbeta en viss del av våra liv för att förtjäna möjligheter till pension. Vi bör dock inte enbart utgå ifrån antalet år sedan en person föddes, då korttidsutbildade generellt träder in på arbetsmarknaden tidigare än långtidsutbildade. De har alltså varit en del av arbetskraften från en yngre ålder. Människor med kortare utbildning har oftare ett arbete som innebär påfrestningar som kan inverka negativt på hälsotillståndet och som till och med kan påskynda det biologiska åldrandet. Dessutom lever korttidsutbildade generellt sett inte lika länge som långtidsutbildade, vilket delvis även avspeglar skilda livs- och arbetsvillkor.Den svenska sjukförsäkringsreformen 2008 avsåg att få tillbaka människor i arbete. Men studien fann att den faktiskt bidrog till att fler gick i tidig ålderspension av dem som var i åldern 55–64 år. Ökningen var störst bland korttidsutbildade. Mer än 5 procent fler gick i tidig ålderspension då det blev svårare att få sjukpenning och sjukersättning. Vi kan notera att det är vanligare att manliga chefer tar ut tidig ålderspension, jämfört med kvinnliga maskinskötare inom tillverkningsindustrin. I vissa yrken är det dessutom vanligare att människor, trots pension, både orkar och faktiskt ges möjlighet att arbeta vidare om de har en specialkompetens som efterfrågas. Om vi endast kombinerar ekonomiska morötter med piskor finns en stor risk att vi ökar klyftan mellan grupper som både kan och vill fortsätta att yrkesarbeta och personer som av olika skäl inte längre kan eller orkar.Ta nytta av den forskning som vi har tagit fram. Ett hållbart och acceptabelt pensionssystem måste utformas utifrån personliga förutsättningar och förhållanden i arbetslivet. Ett hållbart arbetsliv för allt fler i vår åldrande befolkning fordrar att vi samtidigt beaktar faktorer som relaterar till biologisk/kroppslig ålder, mental/kognitiv ålder samt social ålder/livsloppsfas och våra attityder som är kopplade till ålder. Vi måste ta större hänsyn till olika förutsättningar och varierande funktionsförmåga och utifrån detta anpassa de åtgärder som gör att arbetslivet blir möjligt och hållbart för allt fler även i högre ålder.”Morötter” är viktigare för en god arbetshälsa och hög produktivitet än en piska i form av oron för en dålig ekonomi.Forskning visar att pedagogik som bygger på ”morötter” oftast är betydligt bättre än ”piskor” för att nå framgångsrika och långsiktiga mål. ”Morötter” i samhället, för organisationer, företag och individer är därför viktiga för god arbetshälsa och fortsatt produktivitet och kan bidra till ett längre arbetsliv även för grupper som tidigare inte ens klarat av att arbeta fram till pensionsåldern. Genom forskning inom området har bland annat swage-modellen utarbetats. Detta är ett verktyg som visar på komplexiteten i ett hållbart arbetsliv och tillsammans med systematiskt arbetsmiljöarbete, handlingsplaner och åtgärder syftar till ett mer hållbart arbetsliv. Morötter är enligt forskningen i detta sammanhang åtgärder för en god fysisk och mental arbetsmiljö, avpassad arbetsbelastning, stödjande teknik, att man kan anpassa arbetstakten, alternativa arbetstidsmodeller vid behov. Det är viktigt att man känner sig trygg och förväntas och tillåts vara delaktig, att man blir sedd av chefen och arbetskamraterna. Att de egna arbetsuppgifterna upplevs som meningsfulla och behövda av andra skapar självförverkligande och tillfredsställelse i arbetet. Att man känner att ens arbetsuppgifter och man själv är viktig för organisationen och företaget. Att man trots högre ålder inkluderas i olika nysatsningar och får tillgång till kompetensutveckling och inte blir åsidosatt eller åldersdiskriminerad. Utvärderingar visar att de äldre medarbetarna som fick några av dessa anpassningar och möjligheter var mer effektiva, utvilade, stimulerade när de var på arbetet samtidigt som sjukfrånvaron minskade. Vilket i sin tur bidrar till ett längre arbetsliv för grupper som tidigare inte klarat av att arbeta fram till pensionsåldern. I organisationer som bygger på en deltagar- och lärandekultur rustas de anställda för att klara omställningar, nya arbetsuppgifter och vid behov även yrkesbyten.Med en åldrande befolkning där allt fler lever allt längre behöver vi arbeta till en högre ålder i framtiden för att pensionssystemet ska hålla. Men ”morötter” är viktigare för en god arbetshälsa och hög produktivitet än en piska i form av oron för en dålig ekonomi. Det kräver också att vi ändrar våra attityder och förhållningssätt till äldre på arbetsmarknaden, vilket vi bäst gör genom att organisationer och företag får incitament till och erbjuder mer individanpassade arbetsvillkor, särskilt för personer i högre ålder. Låt oss därför använda den framtagna kunskapen i praktiken för att göra arbetslivet friskt och hållbart för alla åldrar.

Vi är oroade över senare ålderspension

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Var fjärde person blir i dag sjuk till följd av sitt arbete. Att höja pensionsåldern för alla yrkesgrupper, utan konkreta åtgärder för att minska ohälsan, är därför problematiskt och mycket oroande. Det är, enligt forskarna, inte långsiktigt samhällsekonomiskt lönsamt att utan andra åtgärder höja pensionsåldern för alla. Vi – 54 forskare – är mycket oroade över konsekvenserna av att, som föreslagits, senarelägga ålderspensionen.Förslaget utgår i princip från arbetskraftsdeltagande i princip enbart styrs av ekonomin, medan forskningen visar att det bara är en av flera faktorer som styr hur länge och hur mycket människor väljer att arbeta.Det här sättet att lösa problemet med en åldrande befolkning och ett sviktande pensionssystem är inte samhällsekonomiskt lönsamt på lång sikt, utan riskerar bara att flytta runt folk mellan olika ersättningssystem. Pensionssystemet bygger på att vi ska arbeta en viss del av våra liv för att tjäna in vår pension. Vi bör dock inte enbart utgå ifrån ålder eller antalet år sedan en person föddes då korttidsutbildade generellt träder in på arbetsmarknaden tidigare än långtidsutbildade. De med kortare utbildningstid har alltså varit en del av arbetskraften från en yngre ålder. Människor med kortare utbildning har också oftare ett arbete som innebär påfrestningar som kan inverka negativt på hälsotillståndet och som till och med kan påskynda det biologiska åldrandet. Dessutom lever korttidsutbildade generellt sett inte lika länge som långtidsutbildade, vilket delvis även avspeglar skilda livs- och arbetsvillkor.Ta nytta av den forskning som vi har tagit fram. Ekonomin är självklart viktigt för att vi ska vilja arbeta, men den är som sagt enbart en av flera faktorer med betydelse vårt arbetsliv.Hälsotillståndet, både det fysiska och det mentala, har en avgörande betydelse för hur länge och hur mycket vi orkar arbeta. Ett fysiskt och mentalt belastande arbete är en stark riskfaktor för en nedsatt hälsa i slutet av arbetslivet. Arbetstid, arbetstakt och möjlighet till återhämtning spelar en allt större roll ju äldre vi blir. Andra aspekter är arbetsinnehåll, hur meningsfulla och stimulerande arbetsuppgifterna är, balansen mellan arbete och familjesituation och fritidsaktiviteter. Organisationskultur, ledarskapet, stöd i arbetet och kompetens har stor betydelse för om vi ska kunna och vilja arbeta till en högre ålder. Vi måste ta större hänsyn till olika förutsättningar och varierande funktionsförmåga och utifrån detta anpassa de åtgärder som gör att arbetslivet blir möjligt och hållbart för allt fler även i högre ålder.Ett hållbart och acceptabelt pensionssystem måste därför utformas utifrån personliga förutsättningar och förhållanden i arbetslivet. Ett hållbart arbetsliv för allt fler i vår åldrande befolkning fordrar att vi samtidigt beaktar faktorer som relaterar till biologisk/kroppslig ålder, mental/kognitiv ålder samt social ålder/livsloppsfas samt de attityder som är kopplade till ålder.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to explore older workers’ motivation for a full or extended working life. With particular focus on assistant nurses aged 55–64 years, working in the elderly care sector. Focus group interviews were conducted with five different groups of assistant nurses. Inductive thematic analysis was used to analyse the interviews and five main themes were developed from the data: ‘Organisational issues’, ‘Health-related problems’, ‘Private issues’, ‘Meaningfulness and appreciation’ and ‘Social support’. Several of the main themes concerned problems with too high work demands of the assistant nurses. These findings suggest that it is important to improve the working conditions of assistant nurses in order to create a more sustainable working life. Increasing the number of staff and improving recovery opportunities and work–life balance could be important steps to improving the working conditions for this group. Finally, upgrading the competency and professionalism of assistant nurses could help to increase the motivation for a full or extended working life.

Osteomyelitis Risk in Patients With Transfemoral Amputations Treated With Osseointegration Prostheses.
- 2017

Tidskriftsartikel (refereegranskat)abstract
- Percutaneous anchoring of femoral amputation prostheses using osseointegrating titanium implants has been in use for more than 25years. The method offers considerable advantages in daily life compared with conventional socket prostheses, however long-term success might be jeopardized by implant-associated infection, especially osteomyelitis, but the long-term risk of this complication is unknown.(1) To quantify the risk of osteomyelitis, (2) to characterize the clinical effect of osteomyelitis (including risk of implant extraction and impairments to function), and (3) to determine whether common patient factors (age, sex, body weight, diabetes, and implant component replacements) are associated with osteomyelitis in patients with transfemoral amputations treated with osseointegrated titanium implants.We retrospectively analyzed our first 96 patients receiving femoral implants (102 implants; mean implant time, 95months) treated at our center between 1990 and 2010 for osteomyelitis. Six patients were lost to followup. The reason for amputation was tumor, trauma, or ischemia in 97 limbs and infection in five. All patients were referred from other orthopaedic centers owing to difficulty with use or to be fitted with socket prostheses. If found ineligible for this implant procedure no other treatment was offered at our center. Osteomyelitis was diagnosed by medical chart review of clinical signs, tissue culture results, and plain radiographic findings. Proportion of daily prosthetic use when osteomyelitis was diagnosed was semiquantitatively graded as 1 to 3. Survivorship free from implant- associated osteomyelitis and extraction attributable to osteomyelitis respectively was calculated using the Kaplan-Meier estimator. Indication for extraction was infection not responsive to conservative treatment with or without minor débridement or loosening of implant.Implant-associated osteomyelitis was diagnosed in 16 patients corresponding to a 10-year cumulative risk of 20% (95% CI 0.12-0.33). Ten implants were extracted owing to osteomyelitis, with a 10-year cumulative risk of 9% (95% CI 0.04-0.20). Prosthetic use was temporarily impaired in four of the six patients with infection who did not undergo implant extraction. With the numbers available, we did not identify any association between age, BMI, or diabetes with osteomyelitis; however, this study was underpowered on this endpoint.The increased risk of infection with time calls for numerous measures. First, patients should be made aware of the long-term risks, and the surgical team should have a heightened suspicion in patients with method-specific presentation of possible infection. Second, several research questions have been raised. Will the surgical procedure, rehabilitation, and general care standardization since the start of the program result in lower infection rates? Will improved diagnostics and early treatment resolve infection and prevent subsequent extraction? Although not supported in this study, it is important to know if most infections arise as continuous bacterial invasion from the skin and implant interface and if so, how this can be prevented?Level IV, therapeutic study.

Everyday Mobility and Travel Activities during the first years of Retirement
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Mobility is central to living an independent life, to participating in society, and to maintaining well-being in later life. The point of departure in this thesis is that retirement implies changes in time-space use and interruption in routines, which influence demands and preconditions for mobility in different ways. The aim of this thesis is to explore mobility strategies and changes in mobility upon retirement and how mobility develops during the first years of retirement. A further aim is to provide knowledge of the extent to which newly retired people maintain a desired mobility based on their needs and preconditions. The thesis is empirically based on travel diaries kept by newly retired people, and qualitative interviews with the same persons, and follow-up interviews three and a half years later. The results show that mobility is a way of forming a structure in the new everyday life as retirees by getting out of the house, either just for a walk or to do errands. Many patterns of everyday life remain the same upon retirement, but the informants also merge new responsibilities and seek new social arenas and activities. As a result, the importance of the car have not changed, but it is used for other reasons than before. After leaving paid work, new space-time constraints are created which influences demands for mobility. The study further shows that “third places” become important, especially among those who live alone, as they give an opportunity to being part of a social context and a reason for getting out of the house. The follow-up interviews revealed that declining health changes the preconditions for mobility. Daily walks had to be made shorter, and the car had to be used for most errands to where they previously could walk or cycle. However, mobility can also be maintained despite a serious illness and a long period of rehabilitation.

Osseointegrated Percutaneous Prosthetic System for the Treatment of Patients With Transfemoral Amputation: A Prospective Five-year Follow-up of Patient-reported Outcomes and Complications
- 2019
-
Ingår i: Journal of the American Academy of Orthopaedic Surgeons. - 1067-151X.

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: Direct skeletal attachment of prostheses has previously been shown to improve patient-reported outcome (PRO) measures of individuals with transfemoral amputation (TFA) at 2-year follow-up. This prospective study reports the outcomes at 5-year follow-up. METHODS: A total of 51 patients (55 legs) with TFA were included in a prospective study. Complications, success rate, and PRO measures were followed for 5 years. RESULTS: The cumulative fixture survival rate at 5 years was 92%, and the revision-free survival rate was 45%. Thirty-four patients had 70 superficial infections. Eleven patients had 14 deep infections. Fifteen patients had mechanical complications. Four fixtures were removed (ie, one deep infection and three loosening). PRO measures showed significant improvements including more use of the prosthesis, better mobility, fewer issues, and improved physical health-related quality of life (all P < 0.0001) compared with baseline. CONCLUSION: Individuals with TFA at 5-year follow-up had significant improvement in PRO measures, but increases in deep infections and mechanical complications are concerning.This is an open access article distributed under the Creative Commons Attribution License 4.0 (CCBY), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To describe the rehabilitation experience and outcome of treatment with bone-anchored prostheses in individuals with bilateral transfemoral amputations (TFAs) treated in Sweden over a period of 25 years. Method: Hospital records were reviewed for all patients with traumatic bilateral TFAs treated until 2015. The use of prostheses, walking aids and wheelchairs was noted. Results: The cohort comprised 12 patients (nine men and three women with a mean age 35 years at treatment) and the median follow-up time was seven years (1-20). At baseline, 9/12 used prostheses and 3/12 did not. The main means of locomotion was in a wheelchair without wearing prostheses (n=8/12) or in a wheelchair in combination with prosthetic walking supported by walking aids (n=4/12). All prosthetic users had problems with sitting comfort. At follow-up, 11/12 patients used prostheses, while one did not. The means of locomotion was prosthetic walking in 3/12 cases, a combination of a wheelchair and prosthetic walking in 4/12, a wheelchair while wearing prostheses but not walking in 4/12 and a wheelchair without wearing prostheses in 1/12. Three patients walked unsupported by walking aids. Seven patients had no problem with prosthetic sitting comfort (n=3 had small problems). Conclusions: Bone-anchored prostheses in patients with bilateral TFAs resulted in more prosthesis use during everyday locomotion, due hypothetically to improved comfort while wearing prostheses. The results further underline the importance of other assistive devices such as wheelchairs and walking aids used in combination with prostheses in this group of patients facing severe functional limitations.

Patients with unilateral transfemoral amputation treated with a percutaneous osseointegrated prosthesis. A cost-effectiveness analysis
- 2018
-
Ingår i: Bone and Joint Journal. - 2049-4394. ; 100-B:4, s. 527-534
-
Tidskriftsartikel (refereegranskat)abstract
- Aims: The aim of this study was to compare the cost-effectiveness of treatment with an osseointegrated percutaneous (OI-) prosthesis and a socket-suspended (S-) prosthesis for patients with a transfemoral amputation. Patients and Methods: A Markov model was developed to estimate the medical costs and changes in quality-adjusted life-years (QALYs) attributable to treatment of unilateral transfemoral amputation over a projected period of 20 years from a healthcare perspective. Data were collected alongside a prospective clinical study of 51 patients followed for two years. Results: OI-prostheses had an incremental cost per QALY gained of €83 374 compared with S-prostheses. The clinical improvement seen with OI-prostheses was reflected in QALYs gained. Results: were most sensitive to the utility value for both treatment arms. The impact of an annual decline in utility values of 1%, 2%, and 3%, for patients with S-prostheses resulted in a cost per QALY gained of €37 020, €24 662, and €18 952, respectively, over 20 years. Conclusion: From a healthcare perspective, treatment with an OI-prosthesis results in improved quality of life at a relatively high cost compared with that for S-prosthesis. When patients treated with S-prostheses had a decline in quality of life over time, the cost per QALY gained by OI-prosthesis treatment was considerably reduced.

Foot anthropometrics in individuals with diabetes compared with the general Swedish population: Implications for shoe design
- 2017
-
Ingår i: Foot and Ankle Online Journal. - : International Foot and Ankle Foundation. - 1941-6806. ; 10:3
-
Tidskriftsartikel (refereegranskat)abstract
- Background: The literature offers sparse information about foot anthropometrics in patients with diabetes related to foot length, foot width and toe height, although these measurements are important in shoe fitting. A poorly fitted shoe is one of many contributory factors in the development of diabetic foot ulcers. The purpose of this study was to describe the foot anthropometrics in groups of patients with diabetes, in groups representing the general population and to explore whether foot anthropometrics differ between patients with diabetes and the general population. Method: Foot anthropometrics (foot length, foot width and maximum toe height) was measured in 164 patients with diabetes, with and without neuropathy (n = 102 and n = 62 respectively). The general population was represented by 855 participants from two sources. Results: Foot length, foot width and toe height varied (220-305 mm; 82-132 mm and 15-45 mm respectively) in the diabetic group and in the group representing the general population (194-306 mm; 74-121 mm and 17-31 mm respectively). Age, gender and BMI influence the foot anthropometrics, however, when adjusting for theses variables the index foot length/width was lower (2.58) in patients with diabetes without neuropathy vs. controls (2.63), p = 0.018. Moreover, patients with diabetes with neuropathy had wider feet (98.6 mm) compared with the controls (97.0 mm), p = 0.047. Conclusions: The individual variations of foot length, foot width and maximum toe height were large. The impact of gender on foot anthropometrics was confirmed and the impact of age and BMI were shown. Patients with diabetes seemed to have a wider forefoot width and a lower foot length to foot width ratio compared to the controls.

Foot deformities, function in the lower extremities, and plantar pressure in patients with diabetes at high risk to develop foot ulcers
- 2015
-
Ingår i: Diabetic Foot & Ankle. - : Informa UK Limited. - 2000-625X. ; 6
-
Tidskriftsartikel (refereegranskat)abstract
- Objective : Foot deformities, neuropathy, and dysfunction in the lower extremities are known risk factors that increase plantar peak pressure (PP) and, as a result, the risk of developing foot ulcers in patients with diabetes. However, knowledge about the prevalence of these factors is still limited. The aim of the present study was to describe the prevalence of risk factors observed in patients with diabetes without foot ulcers and to explore possible connections between the risk factors and high plantar pressure. Patients and methods : Patients diagnosed with type 1 ( n= 27) or type 2 ( n= 47) diabetes (mean age 60.0±15.0 years) were included in this cross-sectional study. Assessments included the registration of foot deformities; test of gross function at the hip, knee, and ankle joints; a stratification of the risk of developing foot ulcers according to the Swedish National Diabetes Register; a walking test; and self-reported questionnaires including the SF-36 health survey. In-shoe PP was measured in seven regions of interests on the sole of the foot using F-Scan ® . An exploratory analysis of the association of risk factors with PP was performed. Results : Neuropathy was present in 28 (38%), and 39 (53%) had callosities in the heel region. Low forefoot arch was present in 57 (77%). Gait-related parameters, such as the ability to walk on the forefoot or heel, were normal in all patients. Eighty percent had normal function at the hip and ankle joints. Gait velocity was 1.2±0.2 m/s. All patients were stratified to risk group 3. Hallux valgus and hallux rigidus were associated with an increase in the PP in the medial forefoot. A higher body mass index (BMI) was found to increase the PP at metatarsal heads 4 and 5. Pes planus was associated with a decrease in PP at metatarsal head 1. Neuropathy did not have a high association with PP. Conclusions: This study identified several potential risk factors for the onset of diabetic foot ulcers (DFU). Hallux valgus and hallux rigidus appeared to increase the PP under the medial forefoot and a high BMI appeared to increase the PP under the lateral forefoot. There is a need to construct a simple, valid, and reliable assessment routine to detect potential risk factors for the onset of DFU.

The D-Foot, for prosthetists and orthotists, a new eHealth tool useful in useful in risk classification and foot assessment in diabetes
- 2017
-
Ingår i: Foot and Ankle Online Journal. - : International Foot & Ankle Foundation. - 1941-6806. ; 10:2
-
Tidskriftsartikel (refereegranskat)abstract
- Background: The prevention and care of foot problems in diabetes begins with a risk classification. Today, the prosthetists and orthotists (CPO) and other health care professionals assess the risk of developing foot ulcers more or less subjectively. The objective of the study was to describe the construction of an eHealth tool, the D-Foot, which generates a risk classification. The reliability of the D-Foot was tested. Methods: The D-Foot includes 22 clinical assessments and four self-reported questions. The content validity was assured by expert group consensus and the reliability was assessed through an empirical test-retest study. Inter- and intra-rater reliability was calculated using patients referred to four departments of prosthetics and orthotics (DPO). Results: The agreement for the risk classification generated using the D-Foot was 0.82 (pooled kappa 0.31, varying from 0.16 to 1.00 at single DPOs). The inter-rater agreement was > 0.80 regarding the assessments of amputation, Charcot deformity, foot ulcer, gait deviation, hallux valgus/hallux varus and risk grade. The inter- and intra-rater agreements for the discrete measurements were > 0.59 and > 0.72 respectively. For continuous measurements, the inter- and intra-rater correlation varied (0.33-0.98 and 0.25-0.99 respectively). Conclusion: The D-Foot gave a reliable risk foot classification. However, there was a variation in the inter- and intra-rater reliability of the assessments included and refinements are needed for variables with low agreement. Based on the results, the D-Foot will be revised before it is implemented in clinical practice.

Cost-effectiveness of antibiotic prophylaxis in elective cesarean section
- 2018
-
Ingår i: Cost Effectiveness and Resource Allocation. - : BMC. - 1478-7547. ; 16
-
Tidskriftsartikel (refereegranskat)abstract
- Background: The proportion of pregnant women delivered by cesarean section has increased steadily during the past three decades. The risk of infection is 10-fold augmented after elective cesarean section compared to vaginal delivery. Antibiotic prophylaxis may reduce endometritis by 62% and superficial wound infection by 38% after elective cesarean section. International guidelines recommend antibiotic prophylaxis in elective cesarean section, but this procedure is not routinely followed in Sweden. Studies of costs of antibiotic prophylaxis in cesarean section show conflicting results and are based on substantially different incidence of postoperative infections. No study of costs of antibiotic prophylaxis in elective cesarean section in a Swedish or Nordic context has been pursued. The aim of this study was to investigate if antibiotic prophylaxis is cost-reducing in elective cesarean section in orebro County, Sweden.Methods: All women undergoing elective cesarean in the Region orebro County health care system during 2011-2012 were eligible for inclusion. Postoperative infections and risk factors for infections were registered. A hypothetical situation in which all participants had received antibiotic prophylaxis was compared to the actual situation, in which none of them had received antibiotic prophylaxis. The reduction in the risk of postoperative infections resulting from antibiotic prophylaxis was based on a meta-analysis. Costs for in-patient care of postoperative infections were extracted from the accounting system, and costs for out-patient care were calculated according to standard costs. Costs for antibiotic prophylaxis were calculated and compared with the cost reduction that would be implied by the introduction of such prophylaxis.Results: The incidences of deep and superficial surgical site infection were 3.5% and 1.3% respectively. Introduction of antibiotic prophylaxis would reduce health care costs by 31 Euro per cesarean section performed (95% credible interval 4-58 Euro). The probability of cost-saving was 99%.Conclusions: Antibiotic prophylaxis in elective cesarean section is cost-reducing in this health care setting. Our results indicate that the introduction of antibiotic prophylaxis in elective cesarean section can also be cost-saving in low infection rate settings.Trial registration Ethical approval was given by the Regional Ethical Review Board in Uppsala (registration number 2013/484).

Konferensbidrag (refereegranskat)abstract
- BACKGROUNDWalking with a lower-limb prosthesis while performing a secondary task (dual-tasking) has been suggested to increase demand on attentional resources, negatively affecting balance and gait performance.[1, 2] Brain imaging research has suggested that microprocessor-controlled prosthetic knees (MPKs) reduce attentional demands during single-task walking.[3] To date the effects of MPK on brain activity during dual-task walking has not been investigated.AIMTo evaluate effects of single- and dual-task walking on cortical brain activity in individuals using a non-MPK or MPK and controls and compare differences between the 3 groups.METHODA cross-sectional study was performed involving twenty-nine individuals with a transfemoral amputation or knee disarticulation who were provided with either a non-MPK or an MPK, and 16 controls. Functional near-infrared spectroscopy was used to evaluate cortical brain activity (oxygenated haemoglobin (oxyHb) concentration level changes) while participants walked on a stable level surface and simultanously performed 2 dual-task activities; 1) walking while sorting through keys; and, 2) walking in sequence around randomly number cones. Temporospatial variables was recorded for each activity.RESULTSIncreased brain activity (oxyHb concentration level changes) were observed when a secondary task was added in the MPK-group (p=.000) and in the control group (p=.007). No significant differences were observed between single- and dual-task walking in the non-MPK group (p>.05). Significantly increased brain activity (oxyHb concentrations level changes) was observed during single-task walking in the non-MPK group when compared to the MPK-group and controls. Significantly different results in temporospatial parameters were also observed.DISCUSSION AND CONCLUSIONResults suggest that dual-task walking increases cognitive demand in individuals fitted with MPKs and controls. The lack of difference with the non-MPK group may suggests that their maximum capacity was already reached during single-task walking.REFERENCES[1] Morgan, Prosthet Orthot Int 2016.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: To undergo a lower limb amputation is a traumatic experience affecting the individual on physical as well as psychological levels and often leading to limitations in a person´s daily life. Following an amputation individual often receive a prosthesis to address impairments in mobility and functioning. The mechanical properties of the prosthesis can vary, and the choice of specific components to include in the device has been demonstrated to influence patient outcomes. Studies investigating the relative effects of different prosthetic knee components have generally focused upon physical and biomechanical outcomes, providing a rather narrow view of health-related states in prosthetic users. There is a need to view health and wellbeing of prosthetic users from a broader perspective by evaluating outcomes that reflect a variety of different factors that can influence their functioning.Aim: The overall aim of this thesis was to describe and compare functioning in individuals with a trans-femoral amputation or knee disarticulation and to evaluate the relative effects of using non-microprocessor-controlled prosthetic knees (non-MPK) or microprocessor-controlled prosthetic knees (MPK).Methods: The four studies presented in this thesis used a cross-sectional, quantitative design with different types of data collection methods. These included self-report measures, capacity tests, a survey with two questionnaires and a measure of cortical brain activity during normal level waking and while performing a secondary task. One group of 42 individuals with lowerlimb amputations, using a prosthetic knee with or without microprocessor-control was included in the survey study. Another group of 29 individuals with a lower limb amputation, using a prosthetic knee with or without a microprocessor-control and a control group (n=16) participated in the remaining studies. Statistical tests were used to compare differences between groups using different knee joints, between prosthesis users and controls.Results: Individuals using a non-MPK had lower self-reported mobility and balance confidence as well as poorer results on mobility tests compared to those using an MPK. Results revealed no significant differences in self-rated health, daily step count or general self-efficacy. Increased cortical brain activity was seen in frontal cortex in individuals using a non-MPK in single-task walking compare to the MPK group and controls. A significant increase in brain activity was also seen in prefrontal cortex in dual-task walking compared to single-task walking in those walking with an MPK and controls.Conclusion: Combined results of all four studies suggest that persons provided with an MPK had better mobility, both self-rated and objectively evaluated, and better self-rated balance confidence than those who were using a non-MPK. Results also showed that an individual’s belief in their own ability was associated with the number of hours they use their prosthesis per week. Participants using a non-MPK had higher levels of cortical brain activity in the frontal cortex during walking, suggesting that the attentional demand required to walk was greater than for individuals using an MPK. Of particular interest for health professionals involved in prosthetic rehabilitation was the finding that significant increases in attentional demand were not always reflected in temporospatial gait parameters. This suggests that cognitive demands may not always be reflected in variables that are commonly evaluated in the clinical setting.

- Purpose: To measure self-efficacy in a group of individuals who have undergone a lower-limb amputation and investigate the relationship between self-efficacy and prosthetic-specific outcomes including prosthetic use, mobility, amputation-related problems and global health. A second purpose was to examine if differences exist in outcomes based upon the type of prosthetic knee unit being used. Method: Cross-sectional study using the General Self-Efficacy (GSE) Scale and the Questionnaire for Persons with a Transfemoral Amputation (Q-TFA). Forty-two individuals participated in the study. Twenty-three used a non-microprocessor-controlled prosthetic knee joint (non-MPK) and 19 used a microprocessor-controlled prosthetic knee joint (MPK). Results: The study sample had quite high GSE scores (32/40). GSE scores were significantly correlated to the Q-TFA prosthetic use, mobility and problem scores. High GSE scores were related to higher levels of prosthetic use, mobility, global scores and negatively related to problem score. No significant difference was observed between individuals using a non-MPK versus MPK joints. Conclusions: Individuals with high self-efficacy used their prosthesis to a higher degree and high self-efficacy was related to higher level of mobility, global scores and fewer problems related to the amputation in individuals who have undergone a lower-limb amputation and were using a non-MPK or MPK knee.

- Background: Individuals using a lower-limb prosthesis indicate that they need to concentrate on every step they take. Despite self-reports of increased cognitive demand, there is limited understanding of the link between cognitive processes and walking when using a lower-limb prosthesis.Objective: The objective was to assess cortical brain activity during level walking in individuals using different prosthetic knee components and compare them to healthy controls. It was hypothesized that the least activity would be observed in the healthy control group, followed by individuals using a microprocessor-controlled prosthetic knee and finally individuals using a non-microprocessor-controlled prosthetic knee.Study Design: Cross-sectional study.Methods:: An optical brain imaging system was used to measure relative changes in concentration of oxygenated and de-oxygenated haemoglobin in the frontal and motor cortices during level walking. The number of steps and time to walk 10 m was also recorded. The 6-min walk test was assessed as a measure of functional capacity.Results: Individuals with a transfemoral or knee-disarticulation amputation, using non-microprocessor-controlled prosthetic knee ( n = 14) or microprocessor-controlled prosthetic knee ( n = 15) joints and healthy controls ( n = 16) participated in the study. A significant increase was observed in cortical brain activity of individuals walking with a non-microprocessor-controlled prosthetic knee when compared to healthy controls ( p < 0.05) and individuals walking with an microprocessor-controlled prosthetic knee joint ( p < 0.05).Conclusion: Individuals walking with a non-microprocessor-controlled prosthetic knee demonstrated an increase in cortical brain activity compared to healthy individuals. Use of a microprocessor-controlled prosthetic knee was associated with less cortical brain activity than use of a non-microprocessor-controlled prosthetic knee.Clinical Relevance: Increased understanding of cognitive processes underlying walking when using different types of prosthetic knees can help to optimize selection of prosthetic components and provide an opportunity to enhance functioning with a prosthesis.

- Background: Load-bearing exercises are performed by transfemoral amputees fitted with an osseointegrated implant to facilitate bone remodelling. Objective: This study presents the loading compliance comparing loads prescribed and applied on the three axes of the implant during static load-bearing exercises with a specific emphasis on axial and vectorial comparisons. Study design: Cohort study. Methods: A total of 11 fully rehabilitated unilateral transfemoral amputees fitted with an osseointegrated implant performed five trials in four loading conditions using a static standing frame. The load prescribed was monitored using a vertical single-axis strain gauge connected to an electronic display. The tri-axial forces applied on the implant were measured directly with an instrumented pylon including a six-channel transducer. The analysis included axial' and vectorial' comparisons corresponding to the difference between the force applied on the long axis of the implant and the load prescribed as well as the resultant of the three components of the load applied and the load prescribed, respectively. Results: The results demonstrated that axial and vectorial differences were significant in all conditions (p<0.05), except for the vectorial difference for the 40kg condition (p=0.182). Conclusion: The significant lack of axial compliance led to systematic underloading of the long axis of the implant. Clinical relevance This study contributes to a better understanding of the load applied on an osseointegrated implant during the static load-bearing exercises that could contribute to improve the design of apparatus to monitor loading exercises as well as clinical guidelines for the loading progression during rehabilitation.

- This study aimed at presenting the intra-tester reliability of the static load bearing exercises (LBEs) performed by individuals with transfemoral amputation (TFA) fitted with an osseointegrated implant to stimulate the bone remodeling process. There is a need for a better understanding of the implementation of these exercises particularly the reliability. The intra-tester reliability is discussed with a particular emphasis on inter-load prescribed, inter-axis and inter-component reliabilities as well as the effect of body weight normalization. Eleven unilateral TFAs fitted with an OPRA implant performed five trials in four loading conditions. The forces and moments on the three axes of the implant were measured directly with an instrumented pylon including a six-channel transducer. Reliability of loading variables was assessed using intraclass correlation coefficients (ICCs) and percentage standard error of measurement values (SEMs). The ICCs of all variables were above 0.9 and the SEM values ranged between 0 and 87. This study showed a high between-participants' variance highlighting the lack of loading consistency typical of symptomatic population as well as a high reliability between the loading sessions indicating a plausible correct repetition of the LBE by the participants. However, these outcomes must be understood within the framework of the proposed experimental protocol.
