Tidskriftsartikel (refereegranskat)abstract
- Background: Hallux rigidus (HR) affects the first metatarsophalangeal joint and is the most common osteoarthritic condition in the foot. The most used surgical treatment for severe cases of HR is an arthrodesis. The aim of this study is to describe patient characteristics, surgical treatment and the patient-reported outcomes for patients treated with arthrodesis for HR using data from Swefoot, the Swedish quality register for foot and ankle surgery.Methods: From Swefoot we extracted data on patients who underwent surgery for HR between January 2014 and December 2019. We included 419 patients with end-stage HR, who had not previously been treated surgically for HR on the same side.The outcome was measured with the Self-reported Foot and Ankle Score (SEFAS) (summary score 0-48) and EuroQol 5 Dimensions (EQ5D) (index 0-1) together with questions regarding appearance, shoe wear and satisfaction. We extracted surgical and patient-reported data preoperatively and 1 year postoperatively.Results: Our patient-population is predominantly female, around 61 years old, and slightly overweight. The arthrodeses are most often fixated with screws and most of the patients are allowed to bear weight immediately after surgery. The mean SEFAS score is 22 preoperatively and 38 postoperatively, the corresponding values for EQ5D index are 0.56 and 0.81 which means that the health-related quality of life (HrQoL) improves significantly after surgery.Conclusion: Patients with severe HR treated with an arthrodesis have reduced pain, improved function and HrQoL according to the patient-reported outcome measures SEFAS and EQ5D. The mean postoperative SEFAS value was close to the mean SEFAS value of the Swedish general population in the same age category. Fixation techniques and postoperative regimen differ among surgeons in the country. This is the first report from Swefoot regarding this patient population.

- Background: Swefoot is a Swedish national registry, that covers surgery in the foot and ankle. Surgical treatment of hallux rigidus (HR) vary within and between countries. The aim of this study was to report baseline variables for patients with HR. Methods: We extracted baseline characteristics, surgical procedures and patient-reported data for patients with HR entered in the registry during the period January 2014 to August 2019. Results: By August 2019, 1818 patients were reported in the registry. 68.9% of the patients were women, the average age was 58 years, the mean BMI was 26.4 kg/m2. 41.9% of the patients underwent a cheilectomy,19.8% a metatarsal osteotomy, 34.3% a fusion, 0.2% an arthroplasty, 0.3% Keller's procedure and 3.5% other methods. The preoperative summary score for SEFAS (Self-reported Foot and Ankle Score) was 26 and for EQ-5D (Euroqol-5 Dimension) 0.60. Conclusion: This study is the first report from Swefoot regarding HR.

- BackgroundPopulation-based register data could be used to improve our knowledge of patients surgically treated for foot and ankle disorders. The quality register Swefoot was recently created to collect surgical and patient-reported data of foot and ankle surgery. This manuscript aims to describe the development and current use of the register.MethodsThe development of Swefoot started in 2014 and currently, data on 16 different diagnoses are collected in 49 units performing foot and ankle surgery. Registrations are performed by the surgeon and the patient.ResultsBetween 2014 and 2020 approximately 20,000 surgical procedures have been registered. 75.1% of the registered patients were women, 9.3% were smokers, 9.3% had a concomitant rheumatoid disease, and 18.4% a BMI larger than 30 kg/m2.ConclusionsThe Swefoot is a unique national register for foot and ankle surgery. It is by now possible to present demographic, surgical, and outcome parameters based on Swefoot.

- Background and purpose — Hallux rigidus (HR) may cause decreased range of motion, joint pain, and gait disturbances. There is a lack of evidence regarding the outcome of different surgical procedures for moderate HR. We report patient-reported outcomes after joint-preserving surgical procedures for moderate HR. Patients and methods — We included 296 patients registered in Swefoot (Swedish national registry of foot and ankle surgery) who underwent primary surgery for moderate HR 2014 through 2018. We extracted information on anthropometrics, grading of HR, chosen surgical procedure, and patient-reported data including the PROMs SEFAS (summary score 0–48) and EQ-5D-3L (index 0–1) preoperatively and 1 year postoperatively. Results — 115 patients underwent metatarsal decompression (i.e., Youngswick) osteotomy (YOT) and 181 underwent cheilectomy. The mean improvement in SEFAS score 1 year after surgery was 12 points (95% CI 10 − 13) for YOT and 10 points (CI 9 − 12) for cheilectomy. Also, EQ-5D improved in both groups. Patients who underwent YOT were more satisfied with the procedure (84% vs. 70% for cheilectomy, p = 0.02). Interpretation — Surgically treated patients with moderate HR improved after both YOT and cheilectomy, according to patient-reported data from Swefoot. Patients who underwent a YOT were more satisfied with their procedure. One possible explanation may be that more patients in the YOT group had a concomitant hallux valgus; however, we have no information on this.

European industrial transformation : the effects of digitization
- 2011
-
Ingår i: Proceedings of the 13th Swedish network for European studies in economics and business conference. ; , s. 1-41

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper reviews the impact of digitization and information technology over several decades in four industries representing a cross-section of the entire economy. It is based on in-depth studies of the raw material production, manufacturing, retailing, and public service sectors in Sweden. The focus is on the content of industrial transformation in the form of new and improved products, improved processes, changed organizational structures, and redefined industry boundaries. Some of these changes are measurable in terms of their economic impact, but most are not. We find that digitization has been a gradual and iterative process involving interrelated technological and organizational changes. This confirms the findings in previous studies that Sweden is the leading country in Europe in adopting IT and may help to explain Sweden’s successful economic performance over the last decade or so.

Age- and Gender-Specific Normative Values for the Self-Reported Foot and Ankle Score (SEFAS)
- 2018
-
Ingår i: Foot & Ankle International. - : SAGE Publications. - 1944-7876 .- 1071-1007. ; 39:11, s. 1328-1334

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The Self-Reported Foot and Ankle Score (SEFAS) is a foot- and ankle-specific patient-reported outcome measurement (PROM) score that has been validated with good results for a variety of foot and ankle disorders. SEFAS is sensitive detecting improvement or deterioration after surgery. However, normative values, required to put a specific patient's summary score into perspective, are lacking.METHODS: In this report, we included 396 population-based men and 383 women (43% of the invited individuals), age 20-89 years, who had completed the SEFAS questionnaire and questions regarding anthropometrics and health. We used Mann-Whitney U test to test gender differences and Spearman correlation coefficients to determine any association between SEFAS score and age. We present gender-specific median SEFAS scores with range and 5th to 95th percentiles and mean with standard deviation.RESULTS: The SEFAS normative values were median 48 in men (range 11-48), 5th to 95th percentiles 31 to 48 and mean 45 ± 6, and in women, median 47 (range 6-48), 5th to 95th percentiles 23 to 48 and mean 43 ± 8 (gender comparison P < .001). SEFAS normative values correlated inversely with age (r = -0.12, P < .001).CONCLUSION: In the general population, older age was associated with lower SEFAS value, and men had higher values than women. The population-based normative SEFAS values provided in this study can facilitate quantification of disability related to foot and ankle with and without surgery in the foot and ankle.LEVEL OF EVIDENCE: Level II, prospective comparative study.

Minimally important change, measurement error, and responsiveness for the Self-Reported Foot and Ankle Score
- 2017
-
Ingår i: Acta Orthopaedica. - Abingdon : TAYLOR & FRANCIS LTD. - 1745-3674 .- 1745-3682. ; 88:3, s. 300-304

Tidskriftsartikel (refereegranskat)abstract
- Background and purpose - Patient-reported outcome measures (PROMs) are increasingly used to evaluate results in orthopedic surgery. To enhance good responsiveness with a PROM, the minimally important change (MIC) should be established. MIC reflects the smallest measured change in score that is perceived as being relevant by the patients. We assessed MIC for the Self-reported Foot and Ankle Score (SEFAS) used in Swedish national registries. Patients and methods - Patients with forefoot disorders (n = 83) or hindfoot/ankle disorders (n = 80) completed the SEFAS before surgery and 6 months after surgery. At 6 months also, a patient global assessment (PGA) scaleas external criterionwas completed. Measurement error was expressed as the standard error of a single determination. MIC was calculated by (1) median change scores in improved patients on the PGA scale, and (2) the best cutoff point (BCP) and area under the curve (AUC) using analysis of receiver operating characteristic curves (ROCs). Results - The change in mean summary score was the same, 9 (SD 9), in patients with forefoot disorders and in patients with hindfoot/ankle disorders. MIC for SEFAS in the total sample was 5 score points (IQR: 2-8) and the measurement error was 2.4. BCP was 5 and AUC was 0.8 (95% CI: 0.7-0.9). Interpretation - As previously shown, SEFAS has good responsiveness. The score change in SEFAS 6 months after surgery should exceed 5 score points in both forefoot patients and hindfoot/ankle patients to be considered as being clinically relevant.

Patient-reported outcome for 17,648 patients in 5 different Swedish orthopaedic quality registers before and 1 year after surgery: an observational study
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Background and purpose — The EQ-5D is a patient-reported outcome measure (PROM). To make priorities and allocate resources between patients and surgical procedures it is necessary to evaluate outcome differences, which is why comparing PROMs between registers is important. We compared EQ-5D data and the follow-up rate for selected diag-noses reported to Swedish orthopedic registers before and 1 year after surgery. Patients and methods — Patients from 5 orthopedic registers (Swespine, Swedish Hip Arthroplasty Register, Swedish Knee Arthroplasty Register, Swedankle, and Swe-foot) who, in 2014–2018, underwent surgery in southern Sweden were included in the study. Data on the EQ-5D index, individual questions, and the EQ-VAS at baseline and at the 1-year follow-up was compared. Results — 17,648 patients had completed the EQ-5D pre-and 1-year postoperatively. The follow-up rate ranged from 32% to 88%. All registers showed a statistical and clinically relevant improvement in the EQ-5D index (mean improvement 0.29–0.39), where patients who underwent hip arthro-plasties experienced the largest improvement. The EQ-5D index improvements in patients with foot and ankle surgeries were larger than for patients with knee arthroplasties and spinal surgeries. The dimensions “self-care” and “usual activities” had the largest change in patients reporting “some problems.” Conclusion — All 5 registers showed a clinically relevant improvement 1 year postoperatively regarding the EQ-5D index, supporting continuous resource allocation to these groups of patients and surgical procedures. However, using PROM data to present register differences was chal-lenged by the high number of non-responders.

Validation of Two Foot and Ankle Scores – SEFAS (Self-reported Foot And Ankle Score) and AOFAS
- 2014
-
Konferensbidrag (refereegranskat)abstract
- INTRODUCTION: The American Orthopedic Foot and Ankle Score (AOFAS) is for many foot and ankle surgeons the gold standard for evaluation of foot and ankle disorders. The score comprises of four different questionnaires depending on which region is evaluated, and covers three different constructs; pain, function and range of motion and alignment. AOFAS however, requires clinical examination, and can therefore not be used as a patient-reported outcome measure (PROM). In contrast, the Self-Reported Foot and Ankle Score (SEFAS) is a PROM that recently has been validated with good results in patients with foot and ankle disorders. The SEFAS contains 12 questions and covers different constructs such as pain, function and limitation of function. The aim of this study was to compare the SEFAS and AOFAS in patients with disorders in the great toe, the hindfoot and ankle, taking psychometric properties for scores into account.PATIENTS AND METHODS: The SEFAS and AOFAS scores were completed by 73 patients with disorders in the great toe and by 89 patients with disorders in the hindfoot or ankle. The time it took to complete the questionnaire was measured in 17 patients. In all patients, construct validity for SEFAS versus AOFAS was estimated by Spearman´s correlation coefficient and we also evaluated if there were any floor and ceiling effects. Test-retest reliability (intra-observer reliability) was measured for SEFAS in 68 patients and for AOFAS in 33 patients with intra-class correlation coefficient (ICC). Inter-observer reliability was calculated in nine patients for AOFAS using ICC. Responsiveness, i.e. the ability of a score to detect changes after a surgical intervention, was estimated by effect size (ES) and standardized response mean (SRM) in 120 patients for SEFAS and in 112 patients for AOFAS.RESULTS: The SEFAS was completed more than three times faster than AOFAS (165 seconds versus 515 seconds). SEFAS had good convergent validity (strong correlation) with AOFAS with a Spearman´s correlation coefficient of 0.64 in patients with great toe disorders and 0.65 in patients with hind foot/ankle disorders. There were no floor or ceiling effects in either of the scores. ICC was in patients with great toe disorders 0.94 (95% CI: 0.87-0.97) for SEFAS and 0.77 (95% CI: 0.39-0.93) for AOFAS, and in patients with hindfoot/ankle disorders 0.92 (95%CI: 0.85-0.95) for SEFAS and 0.52 (95%CI: 0.13-0.77) for AOFAS. ES was 1.4 for SEFAS and 1.8 for AOFAS and SRM 1.4 for SEFAS and 1.6 for AOFAS in patients with great toe disorders. ES was 1.2 for SEFAS and 1.1 for AOFAS and SRM 1.1 for SEFAS and 0.9 for AOFAS in patients with hindfoot/ ankle disorders. Inter-observer reliability was 0.43 (95% CI: 0.0-0.84) for AOFAS.DISCUSSION AND CONCLUSION: In this study there was a strong correlation between SEFAS and AOFAS indicating good construct validity for SEFAS. Both scores had good responsiveness and no floor or ceiling effects. The test-retest reliability was better for SEFAS than AOFAS while the inter-observer reliability was low for AOFAS. Finally, SEFAS was completed three times faster than AOFAS. In conclusion we consider SEFAS at least equal to AOFAS for evaluation of patients with foot and ankle disorders, and as no clinical examination is demanded in SEFAS, it is an ideal instrument for evaluation of clinical patient outcome in national registers.
