COVID-19 risk perceptions, worries and preventive behaviors in patients with previous myocardial infarction: results from the myocardial infarction registry Augsburg.

Despite the known association of chronic cardiovascular diseases and more severe courses of COVID-19, little is known about individual risk perception of patients with a history of acute myocardial infarction (AMI) and resulting preventive behaviours. In May 2020, a postal survey was conducted, including 150 patients with previous AMI from the myocardial infarction registry Augsburg. The study objective was to assess COVID-19 knowledge, individual risk perception, worries, infection likelihood and preventive behaviours in this patient cohort. From the 100 respondents, 69.7% perceived themselves to be at high risk of developing a severe course of COVID-19. There was a significant positive correlation between dangerousness assessment and knowledge on COVID-19. Despite a majority (70%) of patients rating their susceptibility for an infection as moderate to very high, the individual likelihood of being infected was rated at only 3%. Almost 70% of patients with previous MI classified themselves at high risk for a severe course of COVID-19 infection. As seen in other risk groups as well, the availability of valuable information sources as well as the support in individual risk reduction strategies and psychological coping mechanisms are mandatory, especially since higher knowledge correlates with dangerousness assessment and might lead to better compliance with preventive behaviours.

Social and psychosocial effects on atopic eczema symptom severity - a scoping review of observational studies published from 1989 to 2019.

Social and psychosocial factors are thought to have an effect on the course of atopic eczema. The aim of this scoping review was to search for and summarize observational studies that investigated the effects of (psycho-)social factors on symptoms in atopic eczema and to identify research gaps. We searched PubMed and PsycINFO for literature published between 1 January 1989 and 31 December 2019 using a systematic search strategy. We included observational studies that analysed the effect of (psycho-)social factors on symptom severity in atopic eczema patients. Reviews and non-observational studies, articles with research on animals, and articles with languages other than English or German were excluded. We identified 17 observational studies that met the inclusion criteria. Several studies found significant results for an exacerbating effect of stress on atopic eczema severity. Although coping and social support does not seem to moderate the effect of stress, coping strategies might mediate the impact that stress has on symptoms. Depression is associated with atopic eczema severity. The effect of depression as a consequence of atopic eczema severity is stronger than the effect as an exacerbating factor. Illness identity, anger, frustration and psychosomatic states have been found to affect atopic eczema symptoms. For attachment security, anxiety and social status, contradictory results were found. Statistically non-significant results were reported for personality, being in a partnership, satisfaction with the partnership, childhood experiences and body consciousness. Only the association between psychosocial stress and atopic eczema symptom severity seems robust. To date, other (psycho-)social factors, especially protective and health-promoting factors, were analysed only in a few studies, mostly with low sample sizes and cross-sectional design. Biopsychosocial interactions between stress, protective factors and the course of atopic eczema as well as the psycho-neuroimmunological mechanisms underlying those interactions are considered fields for future research contributions.

[Widening health inequalities? Time trends concerning self-rated health, smoking and obesity between 1984/1985 and 1999/2000 among adults in Augsburg]. / Nimmt die gesundheitliche Ungleichheit zu? : Trends beim subjektiven Gesundheitszustand, beim Rauchen und bei Adipositas zwischen 1984/85 und 1999/2000 bei Erwachsenen in Augsburg.

The analyses focused on time trends in health inequalities in the 25 to 64-year-old population of Augsburg. The analyses are based on four independent cross-sectional surveys from the MONICA/KORA study covering 15 years: 1984/1985 (n = 4,022), 1989/1990 (n = 3,966), 1994/1995 (n = 3,916) and 1999/2000 (n = 3,492). Socioeconomic status (SES) was assessed by educational level and per capita household income with separate analyses for each of these two variables. Both absolute and relative health inequalities were calculated. The results showed that inequalities in self-rated health did not change very much (with some indications for increasing inequalities). However, concerning smoking the results clearly pointed towards increasing health inequalities (for example concerning relative inequalities among women by educational level: significant increase from survey to survey of about 20 %). The prevalence of obesity was increased in all SES groups but the inequalities did not change very much. These time trends show that the efforts aimed at reducing health inequalities should be intensified.

Patient-reported symptoms in acute myocardial infarction: differences related to ST-segment elevation: the MONICA/KORA Myocardial Infarction Registry.

OBJECTIVES: The early recognition of symptoms of myocardial infarction (MI) is crucial for patients with both ST-segment elevation (STEMI) and non-STEMI (NSTEMI). However, to date, only a few studies have examined the differences between patients with STEMI and NSTEMI with regard to the range of presenting MI symptoms. DESIGN: The study population comprised 889 individuals with STEMI and 1268 with NSTEMI, aged 25-74, hospitalized with a first-time MI between January 2001 and December 2006 recruited from a population-based MI registry. The occurrence of 13 symptoms was recorded during a standardized patient interview. RESULTS: Patients with STEMI were significantly younger, more likely to be smokers and less likely to have a history of hypertension or sleep disturbances prior to the acute MI (AMI) event than those with NSTEMI. A total of 50% of the patients attributed their experienced symptoms to the heart. Logistic regression modelling revealed that patients with STEMI were significantly more likely than patients with NSTEMI to complain of vomiting [odds ratio (OR) 2.34, 95% confidence interval (CI) 1.76-3.05], dizziness (OR 1.63, 95% CI 1.30-2.03) and diaphoresis (OR 1.49, 95% CI 1.23-1.81). Furthermore, patients with STEMI were less likely to experience dyspnoea (OR 0.81, 95% CI 0.68-0.98) or pain in the throat/jaw (OR 0.80, 95% CI 0.66-0.98). CONCLUSIONS: Only half of all patients correctly attributed their symptoms to the heart. Patients with STEMI and NSTEMI showed differences regarding several presenting symptoms. Further research is needed to replicate our results, and public awareness of AMI symptoms needs to be improved.

Differences in functioning of individuals with tetraplegia and paraplegia according to the International Classification of Functioning, Disability and Health (ICF).

STUDY DESIGN: Cross-sectional, multicenter study. OBJECTIVES: To identify and quantify the differences in functioning of individuals with tetraplegia versus paraplegia using the International Classification of Functioning, Disability and Health (ICF) as a frame of reference. SETTING: International. METHODS: Functional problems of 1048 participants with spinal cord injury in 16 study centers in 14 countries were recorded using ICF categories. The level of significance and odds ratios (OR) for experiencing each of these functional problems were reported for individuals with tetraplegia and paraplegia. Regression models were adjusted for age, age squared, early post-acute or long-term context, gender and for world regions. RESULTS: Persons with tetraplegia are more at risk than persons with paraplegia to have difficulties in 36.4% categories of the component body functions. In the component body structures, 40% of the categories show significant differences. Individuals with tetraplegia indicate problems in three categories, whereas individuals with paraplegia are more likely to indicate problems in one category. Most categories indicating difficulties (56.6%) for persons with tetraplegia were found for the component activities and participation. The component with the highest congruency was the environmental factors. Overall, 3.7% categories (of the persons with tetraplegia as experienced, 2.4% of the categories as barriers, whereas 4.9% were experienced to be facilitators) obtained OR, indicating individuals with tetraplegia having more difficulties. CONCLUSION: The logistic regression analysis identified a variety of differences in functional problems in individuals with tetraplegia compared with individuals with paraplegia. The ICF has the potential to indicate the differences in health conditions.

The comprehensive ICF core sets for spinal cord injury from the perspective of physical therapists: a worldwide validation study using the Delphi technique.

OBJECTIVE: To validate the International Classification of Functioning, Disability and Health (ICF) Core Set for individuals with spinal cord injury (SCI) in the early post-acute and long-term context from the perspective of physical therapists. SETTING: International. METHODS: Physical therapists experienced in the treatment of SCI were asked about problems, resources and aspects of the environment treated by them, in a three-round electronic mail survey using the Delphi technique. Responses were linked to the ICF by two researches; κ-coefficient was calculated as statistical measure of agreement. RESULTS: In all, 81 experts from 27 countries named 3694 concepts. They were linked to 187 ICF categories for the early post-acute context. Three ICF categories from the component body function, five ICF categories from the component body structures and two ICF categories from the component activities and participation were not represented in the ICF Core Set for the early post-acute context. In all, 207 ICF categories were linked for the long-term context. Four ICF categories from the component body function, five ICF categories from the component body structures and two ICF categories from the component activities and participation were not represented in the ICF Core Set for the long-term context. CONCLUSION: Physical therapists addressed a vast variety of problems that they take care of in their interventions in patients with SCI. The Comprehensive ICF Core Sets covered a high percentage of these problems. Further research is necessary on several responses not covered in the ICF.

The comprehensive ICF core sets for spinal cord injury from the perspective of occupational therapists: a worldwide validation study using the Delphi technique.

OBJECTIVE: To validate the International Classification of Functioning, Disability and Health (ICF) core sets for individuals with spinal cord injury (SCI) in the early post-acute and long-term context from the perspective of occupational therapists (OTs). SETTING: International. METHODS: OTs experienced in the treatment in SCI were asked about problems, resources and aspects of the environment treated by them, in a three-round electronic mail survey using the Delphi technique. Responses were linked to the ICF by two researchers; kappa coefficient was calculated as statistical measure of agreement. RESULTS: In total, 67 experts from 27 countries named 2586 different concepts. For the early post-acute context, 223 concepts were linked to ICF categories. Three ICF categories from the component body function, three ICF categories from the component body structures and five ICF categories from the component activities and participation were not represented in the ICF core set for the early post-acute context with an expert agreement of more than 75%. For the long-term context, 205 concepts were linked to ICF categories. Two ICF categories from the component body function, four ICF categories from the component body structures and two ICF categories from the component activities and participation were not represented in the ICF core set with an expert agreement of more than 75%. CONCLUSION: OTs addressed a vast variety of problems that they take care of in their interventions in persons with SCI. The Comprehensive ICF core sets covered a high percentage of these problems. Further research is necessary on a few aspects that are not included in the ICF core sets for SCI.

[Multimorbidity and successful aging: the population-based KORA-Age study]. / Multimorbidität und erfolgreiches Altern: Ein Blick auf die Bevölkerung im Rahmen der KORA-Age-Studie.

BACKGROUND: The objective of the KORA-Age research consortium is to assess the determinants and consequences of multimorbidity in the elderly and to look into reasons for successful aging in the general public. PATIENTS AND METHODS: In the KORA-Age cohort study 9,197 persons were included who where born in the year 1943 or before and participants of previous KORA cohort studies conducted between 1984 and 2001 (KORA: Cooperative Health Research in the Region of Augsburg). The randomized intervention study KORINNA (Coronary infarct follow-up treatment in the elderly) tested a nurse-based case management program with 338 patients with myocardial infarct and included an evaluation in health economics. RESULTS: A total of 2,734 deaths were registered, 4,565 participants submitted a postal health status questionnaire and 4,127 participants were interviewed by telephone (response 76.2% and 68.9% respectively). A gender and age-stratified random sample of the cohort consisting of 1,079 persons took part in a physical examination (response 53.8%). CONCLUSION: The KORA-Age consortium was able to collect data in a large population-based sample and is contributing to the understanding of multimorbidity and successful aging.

Outcome parameters in spinal cord injury research: a systematic review using the International Classification of Functioning, Disability and Health (ICF) as a reference.

OBJECTIVES: This study is part of the development of an International Classification of Functioning, Disability and Health (ICF) Core Set for spinal cord injury (SCI). Its specific objectives were to identify outcome parameters reported in published studies on individuals with SCI in the early post-acute and chronic situation, and to identify and quantify the concepts of the reported parameters using the ICF as a reference. METHODS: Electronic searches of Medline, EMBASE, PsycINFO and CINAHL from 2001 to 2005 were carried out. All outcome parameters and their underlying concepts were retrieved from the included studies. These concepts were linked to categories of the ICF using standardized rules. RESULTS: From the 6681 abstracts retrieved, 2205 were randomly selected (33.0%) and 281 studies met the inclusion criteria (12.7%). A total number of 5217 concepts were retrieved from standardized and non-standardized measures, of which 4049 (77.6%) could be linked to 175 different ICF categories: 56 out of 114 Body Functions, 19 out of 56 Body Structures, 62 out of 118 Activities and Participation and 38 out of 74 Environmental Factors categories. Second-level categories reported in >20% of all studies were pain, remunerative employment, health services, systems and policies, school education and higher education. CONCLUSION: The ICF provides a valuable reference to identify and quantify the concepts of measures focusing on SCI in the early post-acute and chronic situation. The findings show a great diversity in the consequences of SCI and underscore the importance of social participation and environment for people with SCI.

Functioning and disability in spinal cord injury from the consumer perspective: an international qualitative study using focus groups and the ICF.

STUDY DESIGN: Qualitative, multi-center study. OBJECTIVES: To examine the lived experiences of persons with spinal cord injury (SCI) in both the early post-acute and the long-term context using the International Classification of Functioning, Disability and Health (ICF) as a frame of reference. SETTING: International study sites representing the six World Health Organization world regions. METHODS: A qualitative study using focus groups methodology was conducted. Sample size was determined by saturation. The focus groups were digitally recorded and transcribed verbatim. The meaning condensation procedure was used for the data analysis. The resulting meaningful concepts were linked to ICF categories according to established linking rules. RESULTS: Forty-nine focus groups with 230 participants were performed. Saturation was reached in four out of the six world regions. A total of 3122 and 4423 relevant concepts were identified in the focus groups for the early post-acute and the long-term context, respectively, and linked to a total of 171 and 188 second-level categories. All chapters of the ICF components Body functions, Activities and participation and Environmental factors were represented by the linked ICF categories. In all, 36 and 113 concepts, respectively, are not classified by the ICF and 306 and 444, respectively, could be assigned to the ICF component Personal Factors, which is not yet classified. CONCLUSION: A broad range of the individual experiences of persons with SCI is covered by the ICF. A large number of experiences were related to Personal Factors.

Identification of problems in individuals with spinal cord injury from the health professional perspective using the ICF: a worldwide expert survey.

STUDY DESIGN: Worldwide Internet survey. OBJECTIVES: The specific aims of the study were (1) to identify problems of individuals with SCI in the early post-acute and the long-term context, respectively, addressed by health professionals and (2) to summarize these problems using the ICF. SETTING: International. METHODS: Physicians, nurses, physical therapists, occupational therapists, social workers and psychologists were asked for problems in the functioning and contextual factors of individuals with SCI using open-ended questions. All answers were translated ('linked') to the ICF based on established rules. Absolute and relative frequencies of the linked ICF categories were reported stratified by the context. RESULTS: Out of 243 selected experts, 144 (59.3%) named 7.650 different themes, of which 78.8% could be linked to ICF categories. In the early post-acute context, 30.7% of the 88 categories belonged to the component Body Functions, 14.8% to Body Structures, 30.7% to Activities and Participation and 23.9% to Environmental Factors. In all, 16 ICF categories were unique for the early post-acute context. In the long-term context, 27.2% of the 92 categories belonged to the component Body Functions, 13.0% to Body Structures, 35.9% to Activities and Participation and 23.9% to Environmental Factors. A total of 20 ICF categories were unique for the long-term context. CONCLUSION: Health professionals identified a large variety of functional problems reflecting the complexity of SCI. Unique aspects of functioning exist for the early post-acute and the long-term context, respectively. The ICF provided a comprehensive framework to integrate answers from different professional backgrounds and different world regions.

Identification of the most common problems in functioning of individuals with spinal cord injury using the International Classification of Functioning, Disability and Health.

STUDY DESIGN: Cross-sectional, multicenter study. OBJECTIVES: To identify the most common problems of individuals with spinal cord injury (SCI) in the early post-acute and the long-term context, respectively, using the International Classification of Functioning, Disability and Health (ICF) as a frame of reference. SETTING: International. METHODS: The functional problems of individuals with SCI were recorded using the 264 ICF categories on the second level of the classification. Prevalence of impairment was reported along with their 95% confidence intervals. Data were stratified by context. RESULTS: Sixteen study centers in 14 countries collected data of 489 individuals with SCI in the early post-acute context and 559 in the long-term context, respectively. Impairments in thirteen ICF categories assigned to Body functions and Body structures were more frequently reported in the long-term context, whereas limitations/restrictions in 34 ICF categories assigned to Activities and Participation were more frequently found in the early post-acute context. Eleven ICF categories from the component Environmental Factors were more frequently regarded as barriers, facilitators or both by individuals with SCI in the early post-acute context as compared with individuals with SCI in the long-term context. Only two environmental factors were more relevant for people with SCI in the long-term context than in the early post-acute context. CONCLUSION: The study identified a large variety of functional problems reflecting the complexity of SCI and indicated differences between the two contexts. The ICF has potential to provide a comprehensive framework for the description of functional health in individuals with SCI worldwide.

ICF Core Sets for individuals with spinal cord injury in the long-term context.

STUDY DESIGN: A formal decision-making and consensus process integrating evidence gathered from preparatory studies was followed. OBJECTIVES: The objective of the study was to report on the results of the consensus process to develop the first version of a Comprehensive International Classification of Functioning, Disability and Health (ICF) Core Set, and a Brief ICF Core Set for individuals with spinal cord injury (SCI) in the long-term context. SETTING: The consensus conference took place in Switzerland. Preparatory studies were performed worldwide. METHODS: Preparatory studies included an expert survey, a systematic literature review, a qualitative study and empirical data collection involving people with SCI. Relevant ICF categories were identified in a formal consensus process by international experts from different backgrounds. RESULTS: The preparatory studies identified a set of 595 ICF categories at the second, third or fourth level. A total of 34 experts from 31 countries attended the consensus conference (12 physicians, 6 physical therapists, 5 occupational therapists, 6 nurses, 3 psychologists and 2 social workers). Altogether, 168 second-, third- or fourth-level categories were included in the Comprehensive ICF Core with 44 categories from body functions, 19 from body structures, 64 from activities and participation and 41 from environmental factors. The Brief Core Set included a total of 33 second-level categories with 9 on body functions, 4 on body structures, 11 on activities and participation and 9 on environmental factors. CONCLUSION: A formal consensus process integrating evidence and expert opinion based on the ICF led to the definition of the ICF Core Sets for individuals with SCI in the long-term context. Further validation of this first version is needed.

OBJECTIVES: The aim of this study was to report on the results of the consensus process to develop the first version of a Comprehensive International Classification of Functioning, Disability and Health (ICF) Core Set and a Brief ICF Core Set for individuals with spinal cord injury (SCI) in the early post-acute context. SETTING: The consensus conference took place in Switzerland. Preparatory studies were performed worldwide. METHODS: Preparatory studies included an expert survey, a systematic literature review, a qualitative study and empirical data collection involving people with SCI. ICF categories were identified in a formal consensus process by international experts from different backgrounds. RESULTS: The preparatory studies identified a set of 531 ICF categories at the second, third and fourth levels. From 30 countries, 33 SCI experts attended the consensus conference (11 physicians, 6 physical therapists, 5 occupational therapists, 6 nurses, 3 psychologists and 2 social workers). Altogether 162 second-, third- or fourth-level categories were included in the Comprehensive ICF Core Sets with 63 categories from the component Body Functions, 14 from Body Structures, 53 from Activities and Participation and 32 from Environmental Factors. The Brief Core Set included a total of 25 second-level categories with 8 on Body Functions, 3 on Body Structures, 9 on Activities and Participation, and 5 on Environmental Factors. CONCLUSION: A formal consensus process-integrating evidence and expert opinion based on the ICF led to the ICF Core Sets for individuals with SCI in the early post-acute context. Further validation of this first version is needed.

Validation of the International Classification of Functioning, Disability and Health (ICF) core set for diabetes mellitus from the patient perspective using focus groups.

AIMS: The Comprehensive ICF Core Set for diabetes mellitus (DM) is a specific application of the International Classification of Functioning, Disability and Health (ICF) of the World Health Organization for clinical and research purposes involving the disorder. It represents the typical spectrum of functional problems in patients with DM. The objective of the study was to validate the Comprehensive ICF Core Set for DM from the perspective of patients. The specific aims were to explore the aspects of function and health important to patients with DM using focus group methodology and to examine to what extent these aspects are represented by the Comprehensive ICF Core Set for DM. METHODS: A qualitative study using focus group methodology was conducted. Sampling of patients followed the maximum variation strategy. Sample size was determined by saturation. The focus group discussions were digitally recorded and transcribed verbatim. The meaning condensation procedure was used for data analysis. The resulting meaningful concepts were linked to ICF categories according to established linking rules. RESULTS: Forty patients participated in eight focus groups. Seventy-five of the 85 ICF categories contained in the Comprehensive ICF Core Set for DM were identified by the patients. Forty-seven additional categories that are not covered by the Comprehensive ICF Core Set for DM were identified. CONCLUSIONS: The Comprehensive ICF Core Set for DM could be largely confirmed by the focus groups. Categories currently not covered by the Comprehensive ICF Core Set for DM should be investigated further.

[Use of ICF Core Sets for medical reports concerning patients with low back pain and chronic widespread pain syndrome]. / Anwendung der ICF Core Sets in der Begutachtung von Patienten mit lumbalen Rückenschmerzen und generalisiertem Schmerzsyndrom.

BACKGROUND: Medical reports of the national pension insurance are essential for the national pension regulatory authority to decide on granting services regarding participation as well as retirement pensions due to inability to work. There are guidelines regarding the content of medical reports. It is also generally accepted that the evaluation of functioning is an essential component of them. However, it is still an open question to what extent the standardisation and the objectiveness of medical reports can be improved. The ICF (International Classification of Functioning, Disability and Health) is a framework as well as a common language for describing functioning and disability. ICF Core Sets are lists of disease-specific relevant ICF categories and can be a useful practicable tool for medical reports for national pension insurance. They could support the standardization of the medical reports. The aim of this planned project is to examine whether the ICF Core Sets for low back pain and chronic widespread pain could serve as a useful basis for medical reports for national pension insurance regarding the patients suffering low back pain or chronic widespread pain. METHOD: Six hundred medical reports from patients with low back pain or chronic widespread pain, respectively, will be translated into the language of the ICF using a retrospective qualitative study design. For this translation ('linking') process specialised physicians from the national pension insurance and members of the Institute for Health and Rehabilitations Science will be trained to use established linking rules. STATE OF THE PROJECT: Currently, a total of 244 medical reports from the national pension insurance with the health conditions low back pain or chronic widespread pain were selected by members of the national pension insurance. The medical reports are anonymised in different federal states according to the appropriate requirements. The first 10 medical reports have already being analysed. OUTLOOK: First analyses show that the structure of medical reports varies enormously. Therefore a comparison of the content without having a common basis is hardly possible. This demonstrates the importance of the project and the possible usefulness of the ICF and the ICF Core Sets for structuring the content of medical reports for the national pension insurance.

Relevance of claudication pain distance in patients with peripheral arterial occlusive disease.

BACKGROUND: Determination of both the pain-free and the maximum walking distances is part of a routine program in the angiological examination of patients with PAOD. It is however as yet not clear which of these two parameters is more relevant in determining a patient's pathological condition. PATIENTS AND METHODS: In 150 patients with stable intermittent claudication, the claudication pain distance (CPD) and the maximum pain distance (MPD) were determined on a treadmill at 3.0 km/h and 12% inclination. The results were compared with the angiographic findings, the Doppler pressure values and the subjective quality of life (PAVK-86-Questionnaire). RESULTS: The average pain-free walking distance was 89 +/- 71 m, and the maximum walking distance was 198 +/- 141 m. There was no correlation between both walking distances and the angiographic extent of PAOD. Only the MPD correlated with the ankle systolic Doppler pressure and the ankle/brachial pressure index of the claudicating leg (r = 0.16, p < 0.05 and r = 0.20, p < 0.01). Both the CPD and the MDP had a significant influence on the life quality of the patients (CPD: r = -0.41, p < 0.001; MPD: r = -0.47, p < 0.001). In the multiple regression analysis, beside the body mass index, the MPD was found to be the greatest predictor for the pathologically relevant quality of life dimensions pain, complaints and functional status. CONCLUSIONS: The maximum walking distance correlated in a better way than pain-free walking distance with the objective and subjective assessment criteria of PAOD. Therefore, as regards the stage of the disease and the life quality of the patient, this parameter has a greater importance. This fact deserves to receive greater attention in everyday clinical practice and when conducting clinical trials.

Effects of exercise training program on functional capacity and quality of life in patients with peripheral arterial occlusive disease. Evaluation of a pilot project.

BACKGROUND: In patients with peripheral arterial occlusive disease (PAOD) stage II, exercise training seems to be important to reduce symptoms and improve functional capacity. We evaluated the effects of an out-patient treatment program on walking distance (standardized treadmill testing), training exercise capacity, and disease specific quality of life (PAVK-86 questionnaire). METHODS AND RESULTS: Thirty-one patients aged 70 +/- 2 with intermittent claudicatio in stage IIa/IIb according to Fontaine (n = 18/13) underwent a supervised 12 week exercise training and education outpatient program. During course of intervention, patients demonstrated improvements in pain-free training walking distance (p < 0.001) and repetitions of tiptoe standing (p < 0.05). In standardized treadmill testing, pain-free walking distance was improved by 182% (129 +/- 19 m-->364 +/- 53 m; p < 0.001), and maximum walking distance by 76% (311 +/- 42 m-->546 +/- 63 m; p < 0.01). Before training, mean subscale scores of the PAVK-86 demonstrated distinct impairments concerning pain and functional status. After 12 weeks of intervention, with exception of the subscale complaints, all dimensions of quality of life assessed have improved significantly. The highest effect size was observed for the subscales pain, mood, and functional status. Improvement in the subscale anxiety and pain-free walking distance (treadmill test) correlated significantly (r = 0.46) as well as improvement in the subscale mood and maximum walking distance (r = 0.45). CONCLUSION: In patients with PAOD stage II considerable effects on functional capacity and important dimensions of quality of life can be achieved by a short exercise and education program.

[Development of an illness-specific instrument for assessment of quality of life in patients with arterial occlusive disease (Peripheral Arterial Occlusive Disease 86 Questionnaire)]. / Entwicklung eines krankheitsspezifischen Instruments zur Erfassung der Lebensqualität von Patienten mit arterieller Verschlusskrankheit (PAVK-86 Fragebogen.

Impairment in health-related quality of life in patients with peripheral arterial occlusive disease (PAOD) are well-known to clinicians, but due to the lack of disease specific assessment instruments, have not been systematically investigated. We describe the development and psychometric testing of a 86-items patient-based questionnaire for the assessment of the quality of life in PAOD containing 7 dimensions: functional status, pain, symptoms, mood, disease related anxiety, social life and treatment evaluation. The questionnaire was included along with standard questionnaires in a prospective study with 308 patients suffering from PAOD in Fontaine stages I to IV before and one week into treatment. Psychometric testing pertained to reliability (internal consistency, retest), validity (convergent, discriminant) and sensitivity (treatment-related change over time). In addition patient acceptance of the questionnaire was assessed. Psychometric testing yield exellent results regarding scale structure and reliability of the newly developed questionnaire. Validity was reflected in high correlations with standard generic questionnaires and in discriminating in quality of life between patients according to disease severity. The sensitivity was reflected in improved quality of life ratings in patients with improved treadmill performance. Patients needed 20 minutes for responding and rated the questionnaire to be easily understandable and not exhausting. These results show that the newly developed PAVK-86 questionnaire is a reliable, valid and sensitive instrument for the assessment of quality of life in patients with arterial occlusive disease which can be used in clinical studies, epidemiological research and quality assurance programs.
