Öppna prioriteringar inom nya områden : logopedi, nutritionsbedömning, habilitering och arbetsterapi
- 2011
-
Reports (other academic/artistic)abstract
- Det finns fortfarande ett behov av att öka kunskapen om och stödja den praktiska tillämpningen av riksdagens riktlinjer för öppna prioriteringar inom svensk hälso- och sjukvård. Flera förslag på hur ett sådant stöd kan se ut har tagits fram de senaste åren. Spridning av goda exempel är ett sådant förslag, metodstöd ett annat (PrioriteringsCentrum 2007). En mer påtaglig form av metodstöd är den nationella modell som vuxit fram för att konkretisera innebörden i riktlinjerna (Carlsson m fl 2007). Den får idag anses som välbeprövad inom ett flertal områden och har bidragit till att samsynen och kommunicerbarheten kring prioriteringar har ökat i landet. Erfarenheter visar dock att det behövs pedagogisk vägledning i hur modellen kan tillämpas. För att möta upp efterfrågan på sådant metodstöd erbjuder Prioriteringscentrum handledning i grupp. Den första handledningsgruppen är nu avslutad och det är deltagarnas prioriteringsarbeten som presenteras i denna rapport i syfte att sprida konkreta exempel på försök att tillämpa prioriteringsriktlinjerna.I rapporten presenteras fyra prioriteringsarbeten med fokus på: Regionsamverkan inom arbetsterapi Logopedi Yrkesspecifika prioriteringar på väg till teamet Från projekt till integrerat redskapExemplet med prioriteringar i regionsamverkan utgörs av det prioriteringsarbete som genomförts i det s k femklövernätverket bestående av en samverkansgrupp för arbetsterapeuter i ledningsposition på sjukhusen i Uppland, Västmanland, Södermanland, Gävleborg och Dalarna. Arbetet var ett försök att skapa gemensamma prioriteringar i regionen för ett sjukdomsområde som kändes relevant. Valet kom att falla på arbetsterapi inom reumatologi. Arbetet har sedan huvudsakligen bedrivits i en projektgrupp, bestående av en representant från varje sjukhus där arbetet växlat mellan arbete på hemmaplan och avstämningsträffar i projektgruppen.Försöket har visat att det finns en samsyn inom regionen kring prioriteringar inom arbetsterapi och reumatologi. Säkerheten i prioriteringarna har ökat i och med att fem arbetsterapiorganisationer tillsammans bidragit med ett stort underlagsmaterial bl a genom att delge varandra sina kliniska erfarenheter. Förutsättningarna för en mer likartad vård i regionen har ökat. Arbetet har också gett upphov till frågor om i vilka situationer det är att föredra att prioriteringsarbete bedrivs lokalt, regionvis och/eller nationellt.

Clinical studies in severe heart failure : neurohormonal, electrolyte and metabolic aspects
- 1994
-
Doctoral thesis (other academic/artistic)abstract
- Congestive heart failure is a common and complex syndrome with a poor prognosis. Although heart disease is usually the primary event, the clinical syndrome is characterised by several extra-cardiac manifestations. Neurohormonal activation seems to play a crucial role for these manifestations and the progression of the disease.Twenty-seven consecutive patients with acute left ventricular heart failure were found to have increased plasma concentrations of atrial natriuretic peptide, arginine vasopressin and catecholamines, while the renin-angiotensin system was not activated until diuretic therapy was introduced. To counteract this activation it seems suitable to combine the diuretics with an angiotensin-converting enzyme inhibitor.Skeletal muscle biopsies were performed in 22 patients participating in the CONSENSUS trial, which was a randomised, double-blind, placebo-controlled study of the effects of the angiotensin-converting enzyme inhibitor enalapril on mortality in patients with severe congestive heart failure. The biopsies revealed decreased content of magnesium andpotassium while sodium and water were retained in skeletal muscle. Ventricular arrhythmias occurred frequently. The ventricular arrhythmias seemed to be related to lower serum levels of potassium, but no significant correlations were found to muscle electrolyte content. This may indicate that the ratio of electrolytes across the cell membrane is moreimportant for the development of arrhythmias than changes in the absolute amount of electrolytes are. The muscle biopsies also revealed metabolic derangement with decreased content of energy-rich compunds, such as adenosine triphosphate (ATP), phosphocreatine and glycogen,Treatment with enalapril did not seem to influence these peripheral abnormalities, but some beneficial effect was found regarding the prevalence of ventricular arrhythmias.In another 22 patients with severe congestive heart failure, similar signs of energy depletion were found in skeletal muscle biopsies. Nutritional assessment, based on anthropometry and serum protein levels, revealed signs of malnutrition in only two patients which is in contrast to a previous reported prevalence of 30-50 % in patients with severe congestive heartfailure. Long-term oral dietary supplementation, given in a randomised, double-blind and placebo-controlled manner, did not change muscle energy content, neither did exercise tolerance improve. Thus, malnutrition did not seem to be a prerequisite for the metabolic changes found in skeletal muscle. Consequently, routine dietary supplementation does not seem to be indicated in patients with congestive heart failure.

IL-8 and tumor necrosis factor alpha in heart valves from patients with infective endocarditis
- 2002
-
In: Scandinavian Journal of Infectious Diseases. - : Informa UK Limited. - 0036-5548 .- 1651-1980. ; 34:10, s. 759-762
-
Journal article (peer-reviewed)abstract
- The embedding of bacteria in the vegetation of infective endocarditis impedes the penetration of phagocytic cells. IL-8 has a stimulating effect on the immune system, particularly with respect to chemotaxis and activation of granulocytes. Tumor necrosis factor alpha (TNF-) is 1 of the major proinflammatory cytokines. IL-8 and TNF- were visualized by means of immunohistochemistry in paraffin-embedded heart valve biopsies from 6 patients with infective endocarditis who required cardiac surgery during the active phase of the infection. In 5/6 patients there were signs of inflammation, and in these patients IL-8- and TNF- -containing cells were visualized in the heart valve stromas or vegetations. The largest numbers of IL-8-containing cells, and the greatest amount of inflammation, were seen in patients with short preoperative treatment courses. No such relationships were seen with respect to TNF- -containing cells. These observations may suggest that the occurrence of IL-8-containing cells in infected heart valves could be used as a marker of disease activity.

Infective Endocarditis : aspects of pathophysiology, epidemiology, management and prognosis
- 2008
-
Doctoral thesis (other academic/artistic)abstract
- Infective endocarditis (IE) is a rare but complex disease that is fatal if untreated. With a modern combination of antimicrobial therapy and heart valve surgery, mortality is still 10-20 %. The structure of the endocarditis vegetation impedes the penetration of phagocytic cells such as monocytes and granulocytes. This leads to high bacterial counts inside the vegetation and the need for long treatment courses with a combination of intravenously administered bactericidal antibiotics.The aim of this thesis was to study the changes in epidemiology, management, and mortality at our hospital between 1980 and 2001, and to identify prognostic factors associated with mortality. To assess the issue of referral bias, differences between referred episodes and episodes from our local community were studied. Additional aims were to study the occurrence of the pro-chemotactic cytokines IL-8 and TNF-α in heart valves and vegetations during the active phase of IE, and to study the effect of the glycopeptide antibiotic vancomycin in dense staphylococcal cultures in vitro. As it is a rare and complex disease, management of IE is usually complicated for non-specialists. For this reason a computerised decision support system for IE was developed and evaluated.Between 1980 and 2001, the occurrence of Staphylococcus aureus IE and the use of early heart valve surgery increased significantly, regardless of whether the episodes were referred or of local origin. Glycopeptide antibiotics, mainly vancomycin, were used more frequently, especially among referred patients. Referred patients were younger, predominantly male, had more complications, and received surgical treatment more often than patients from our local community. The reason for the lower frequency of female patients in the referral cohort cannot be explained by more comorbidity or fewer complications. The differences between referred and local episodes seen in our study highlight the need for assessment and adjustment for referral bias in IE studies (Paper I).In six patients who needed early heart valve surgery, the largest numbers of IL-8-containing cells, and the greatest amount of inflammation, were seen in patients with short preoperative antimicrobial treatment courses. No such relationships were seen with respect to TNF-α-containing cells. The IL-8-containing cells and the inflammatory cells were predominantly scattered in the heart valve stroma or in the margin of the vegetation (Paper II). The primary effect of IL-8 is to stimulate chemotaxis of polymorphonuclear neutrophil granulocytes. This indicates that there is no deficiency of IL-8 in the area close to the vegetation as a cause of the localised agranulocytosis often present inside the vegetation.Our study revealed a need for computerised decision support systems (DSSs) in the field of IE, but to be used in clinical practice these DSSs need be part of knowledge bases covering larger domains (Paper IV). Some of our initial ideas described in Paper III, especially the use of Internet technology and the combination of rule-based advice and explanatory hypertext, will probably be included in these knowledge bases.In vitro, there is a rapid reduction of free vancomycin in broth containing dense staphylococcal cultures. Consequently, there is a simultaneous increase in broth MICs, particularly in high inocula, which is not caused by a development of resistance (Paper V). These findings need further evaluation in vivo, but indicate that the dosing regimen of vancomycin is of particular importance in staphylococcal infections with dense inocula, e.g. infective endocarditis.Diabetes mellitus and moderate to severe heart failure were independent risk factors for 6-month mortality in left-sided, Duke definite IE episodes, regardless of referral or local origin of the episodes. Early heart valve surgery had a positive impact on the 6-month mortality in the referral cohort of episodes, which may be due to referral bias (Paper VI).

Femoral artery haemostasis with a pneumatic compression device versus a clamp after coronary angiography
- 1998
-
In: Scandinavian Cardiovascular Journal. - : Informa Healthcare. - 1401-7431 .- 1651-2006. ; 32:5, s. 281-284
-
Journal article (peer-reviewed)abstract
- To evaluate the safety and efficacy of a new pneumatic compression device for achieving haemostasis after femoral artery catheterization, 1,017 patients undergoing selective coronary angiography by a SF unilateral femoral route were prospectively randomised to pneumatic or the routinely used clamp compression technique. All initial bleedings could be controlled in the pneumatic group, whereas in 38 patients (8%) of the clamp group the initial positioning of the clamp was unsuccessful or was not tolerated by the patient (p less than 0.05). Ultrasound Doppler study of the puncture site because of suspected postcatheterization vascular complication revealed two haematomas which needed no further measure and two pseudoaneurysms which were successfully treated with ultrasound-guided compression or surgical repair. The rate of complications requiring treatment (pseudoaneurysms) was 0.2% overall, 0.5% in the clamp group and nil in the pneumatic compression group (NS). We conclude that the pneumatic compression device is effective, convenient and at least as safe as the clamp and, by shortening the time in the catheterization laboratory, offers time for further angiograms.

Treatment with ramipril improves systolic function even in patients with mild systolic dysfunction and symptoms of heart failure after acute myocardial infarction
- 1998
-
In: Clinical Cardiology. - : John Wiley & Sons. - 0160-9289 .- 1932-8737. ; 21:11, s. 807-811
-
Journal article (peer-reviewed)abstract
- Background: Clinical signs of heart failure such as pulmonary rales and dyspnea, ventricular dysfunction, and ventricular arrhythmia are independent predictors of a poor prognosis after acute myocardial infarction (AMI).Hypothesis: The study aimed to assess the effect of ramipril treatment on mildly depressed left ventricular (LV) systolic function, assessed by atrioventricular (AV) plane displacement in patients with congestive heart failure after AMI.Methods: The study was a substudy in the Acute Infarction Ramipril Efficacy Study, a double-blind, randomized, placebo-controlled trial of ramipril versus placebo in patients with symptoms of heart failure after AMI. In all, 56 patients were included in the main study, 4 refused to participate in the substudy, and 4 were excluded for logistical reasons. Echocardiography was performed at entry and after 6 months. Patients who underwent coronary artery bypass grafting during the follow-up period were excluded.Results: At baseline, the patients had modest LV dysfunction, and mean AV plane displacement of 9.7 mm. During follow-up, AV plane displacement increased in ramipril-treated patients from 9.5 to 10.9 mm (p<0.01). No statistically significant changes were seen in the placebo group.Conclusions: Ramipril improves LV systolic function in patients with clinical signs of heart failure and only modest systolic dysfunction after AMI. Measurement of AV plane displacement is a simple and reproducible method for detection of small changes in systolic function and may be used instead of ejection fraction in patients with poor image quality.

Exercise radionuclide ventriculography for predicting postoperative left ventricular function in chronic aortic regurgitation
- 2009
-
In: JACC: Cardiovascular Imaging. - : Elsevier. - 1936-878X. ; 2:1, s. 48-55
-
Journal article (peer-reviewed)abstract
- Objectives: Ejection fraction (EF) reaction upon exercise by radionuclide ventriculography and standard echocardiographic parameters was evaluated as predictors for post-operative left ventricular (LV) function in chronic aortic regurgitation (AR). Background: The optimal timing of surgery for chronic AR is when the left ventricle is still compensating for the volume and pressure overload without irreversible dysfunction. For asymptomatic patients when EF is normal and LV diameters are borderline, exercise testing is recommended by present guidelines. However, only a limited number of studies have been performed, and data are scarce on this subject. Methods: Radionuclide ventriculography with multiple gated acquisition at rest and during exercise was performed in 29 consecutive patients with severe chronic aortic regurgitation pre-operatively and 6 months post-operatively. Patient subgroups were formed based on pre-operative EF exercise response (ΔEF) and were categorized as decreasing (ΔEF <−5%), unaltered (−5% ≤ ΔEF ≤ 5%), and increasing (ΔEF > 5%). A 5% or higher increase was considered normal. The LV diameters and mass were measured by echocardiography. Results: Pre-operative LV diameters were markedly elevated before surgery and diminished significantly after surgery. Left ventricular diameters, LV mass, EF at rest (EFrest), and EF change from rest to exercise (ΔEF) were independent of New York Heart Association functional class. Pre-operative end-diastolic diameter proved to be a predictor for pre- and post-operative ΔEF (p = 0.003; p = 0.04) but not for the nature of the exercise response post-operatively. Patients with decreasing and unaltered EF pre-operatively presented a significantly higher but still abnormal ΔEF post-operatively. Those with increasing EF pre-operatively had a similar response and a normal ΔEF post-operatively. Pre-operative ΔEF was not only a predictor for post-operative ΔEF (p = 0.02) but also classified patients into post-operative subgroups (EF decreasing, p = 0.03; unaltered, p = 0.02; increasing, p = 0.0008). Conclusions: An abnormal EF response to exercise may also occur in patients who do not fulfill criteria for surgery based on LV dimensions or EF. A follow-up of exercise LV function and adjusting the timing of surgery according to the nature of exercise response could, therefore, be beneficial.
