Laying the foundation for an ICF core set for community dwelling older adults in primary care: an expert survey.

BACKGROUND: A holistic biopsychosocial model focused on functioning in individual contexts (environment, task) is better suited to meet the needs of older patients than disease only based models. The International Classification of Functioning, Disability and Health (ICF) is the official standard for describing functional health. As the ICF is too detailed to be used in practice, brief core sets have been developed. OBJECTIVE: This study aimed to identify relevant aspects of functioning for older primary care patients from the perspective of healthcare professionals in Germany. MATERIAL AND METHODS: An internet-based cross-sectional expert survey was conducted in preparation for the development of an ICF core set for community-dwelling patients aged 75 years and older. Open-ended questions to identify the most important aspects of functioning and disability in old age were used. Responses were analyzed based on a content analysis approach to identify relevant concepts in the care of the target population. These concepts were then linked to ICF categories according to established linking rules. RESULTS: A total of 63 experts participated in this survey. Across all responses, 2240 meaningful concepts were identified. A total of 75 ICF categories (4 first level categories, 67 second level categories, 4 code combinations) were identified by at least 5% of respondents and will thus be considered as candidate categories for the final ICF core set. Most of concepts were associated with the environmental factors component. The most frequently identified categories were immediate family and family relationships. CONCLUSION: This survey provides a list of relevant ICF categories from the experts' perspective and together with other preparatory studies will be used for developing an ICF core set for community-dwelling older adults in primary care.

Laying the foundation for a primary care core set of the International Classification of Functioning, Disability and Health (ICF) for community-dwelling older adults: A qualitative study.

OBJECTIVE: To explore relevant areas of functioning from the perspective of community-dwelling adults aged 75 years and over, in order to develop a Core Set of the International Classification of Functioning, Disability and Health (ICF) for community-dwelling older adults for use in primary care. DESIGN: Qualitative study using semi-structured interviews and focus groups. PARTICIPANTS: A total of 27 community-dwelling older adults participated in the interviews and 24 of them in the focus groups. METHODS: Following the proposed methodology of the ICF Research Branch, this is 1 of 4 preparatory studies in the Core Set development process. Within the transcripts, concepts of functioning were identified, based on Mayring's qualitative content analysis using deductive category assignment with the ICF being the category system. RESULTS: Overall 6,667 concepts were identified. Most were linked to the Activities and Participation component. The most frequently identified categories were "recreation and leisure" and "family relationships". CONCLUSION: Categories from all ICF chapters were identified, demonstrating the complexity and multidimensionality of the ageing process, with a special emphasis on the component Activities and Participation. This qualitative study provides a list of relevant categories from the perspective of community--dwelling elderly people, which will be used to develop a Core Set for older primary care patients.

Laying the foundation for an International Classification of Functioning, Disability and Health Core Set for community-dwelling elderly adults in primary care: the clinical perspective identified in a cross-sectional study.

OBJECTIVES: Having more information about the biopsychosocial functioning of their geriatric patients might help physicians better balance medical interventions according to patients' needs. For this reason, we aimed to develop an easy-to-handle International Classification of Functioning, Disability and Health (ICF) Core Set for community-dwelling geriatric patients aged 75 and older in primary care. In this empirical study, we describe the functioning and health of community-dwelling patients aged 75 and older in primary care in Germany and identify the most common problems encountered by these individuals when using the ICF. DESIGN: In this exploratory, cross-sectional study, a health professional conducted semi-structured interviews. SETTING: Community-dwelling older adults aged 75 and older in Germany. PARTICIPANTS: 65 participants (mean age=80.2, SD=3.6). OUTCOME MEASURES: Extended ICF Checklist V.2.1a, patients prioritised chapters of the 'activities and participation' component. RESULTS: The three most common impairments for 'body functions' were visual system functions (ICF-code b210; 89%), blood pressure functions (b420; 80%) and sensations associated with hearing and vestibular functions (b240; 59%). For 'body structures', they were eyes, ears and related structures (s2; 81%), structure of mouth (s320; 74%) and structures related to the digestive, metabolic and endocrine systems (s5; 49%). For the 'activities and participation' component, adequate aids compensated for activity limitations to a certain degree. Still, after having adequate aids, the category in which the participants had the most difficulty was walking (d450; 35%). Participants rated the 'mobility' chapter as the most important of all chapters. 'Environmental factors' were facilitators of participants' functioning. CONCLUSIONS: This empirical study provides a list of ICF categories relevant to older adults from the clinical perspective. Along with lists from the other three preparatory studies, it will form the basis for the development of an ICF Core Set for community-dwelling older adults in primary care. TRIAL REGISTRATION DETAILS: The trial is registered in ClinicalTrials.gov (NCT03384732).

Is it really always only the others who are to blame? GP's view on medical overuse. A questionnaire study.

BACKGROUND: Medical overuse is a common problem in health care. Preventing unnecessary medicine is one of the main tasks of General Practice, so called quaternary prevention. We aimed to capture the current opinion of German General Practitioners (GPs) to medical overuse. METHODS: A quantitative online study was conducted. The questionnaire was developed based on a qualitative study and literature search. GPs were asked to estimate prevalence of medical overuse as well as to evaluate drivers and solutions of medical overuse. GPs in Bavaria were recruited via email (750 addresses). A descriptive data analysis was performed. Additionally the association between doctors' attitudes and (1) demographic variables and (2) interest in campaigns against medical overuse was assessed. RESULTS: Response rate was 18%. The mean age was 54 years, 79% were male and 68% have worked as GP longer than 15 years. Around 38% of medical services were considered as medical overuse and nearly half of the GPs (47%) judged medical overuse to be the more important problem than medical underuse. Main drivers were seen in "patients´ expectations" (76%), "lack of a primary care system" (61%) and "defensive medicine" (53%), whereas "disregard of evidence/guidelines" (15%) and "economic pressure on the side of the doctor" (13%) were not weighted as important causes. Demographic variables did not have an important impact on GPs´ response pattern. GPs interested in campaigns like "Choosing Wisely" showed a higher awareness for medical overuse, although these campaigns were only known by 50% of the respondents. DISCUSSION: Medical overuse is an important issue for GPs. Main drivers were searched and found outside their own sphere of responsibility. Campaigns as "Choosing Wisely" seem to have a positive effect on GPs attitude, but knowledge is still limited.

Laying the foundation for a core set of the International Classification of Functioning, Disability and Health for community-dwelling adults aged 75 years and above in general practice: a study protocol.

INTRODUCTION: With the medical focus on disease, the problem of overdiagnosis inevitably increases with ageing. Considering the functional health of patients might help to discriminate between necessary and unnecessary medicine. The International Classification of Functioning, Disability and Health (ICF) is an internationally recognised tool for describing functional health. However, it is too detailed to be used in primary care practices. Consequently, the aim of this study is to identify relevant codes for an ICF core set for community-dwelling older adults (75 years and above) in primary care. METHODS AND ANALYSIS: The study will follow the methodology proposed by the ICF Research Branch to identify relevant concepts from different perspectives: (1) Research perspective: A systematic review of studies focusing on functional health in old age will be conducted in different databases. Relevant concepts will be extracted from the publications. (2) Patients' perspective: Relevant areas of functioning and disability will be identified conducting qualitative interviews and focus groups with community-dwelling older persons. The interviews will be transcribed verbatim and analysed using the documentary method of interpretation. (3) Experts' perspective: An online survey with open-ended questions will be conducted. Answers will be analysed using the qualitative content analysis of Mayring. (4) Clinical perspective: A cross-sectional empirical study will be performed to assess the health status of community-dwelling older adults using the extended ICF checklist and other measurement tools.Relevant concepts identified in each study will be linked to ICF categories resulting in four preliminary core sets. ETHICS AND DISSEMINATION: Ethical approval for the study was obtained (90_17B). All participants will provide written informed consent. Data will be pseudonymised for analysis. Results will be disseminated by conference presentations and journal publications.

"What they see is what you get": Prescribing antibiotics for respiratory tract infections in primary care: Do high prescribers diagnose differently? An analysis of German routine data.

BACKGROUND: Characteristics of high and low prescribers of antibiotics in German primary care were analysed using population data. We aimed to evaluate differences in prescribing rates and factors being associated with high prescribing, and whether high prescribers made the diagnosis of perceived bacterial infections more often. METHODS: Routine data were provided by the Bavarian Association of Statutory Health Insurance Physicians. Routine data are delivered by primary care practices on a quarterly basis. We analysed data from 2011 and 2012. Patients older than 15 years with respiratory tract infections consulting a primary care physician were selected (6.647 primary care practices). Patient and physician characteristics associated with high prescribing were identified using stepwise logistic regression. RESULTS: Mean prescribing rate of antibiotics was 24.9%. Prescribing rate for high prescribers was 43.5% compared to 8.5% for low prescribers. High prescribers made the diagnosis of perceived bacterial infections more often (Mhigh = 64.5%, Mlow = 45.2%). In the adjusted regression model, perceived bacterial infections were strongly associated with high prescribing (OR = 13.9, 95% CI [10.2, 18.8]). Treating patients with comorbidities was associated with lower prescribing of antibiotics (OR = 0.6, 95% CI [0.4, 0.8]). High prescribers had a higher practice volume, a higher degree of prescribing dominance, and were situated more often in deprived areas and in rural settings. INTERPRETATION: Compared to findings of studies in other European countries, prescribing rates were low. There was a considerable difference between prescribing rates of high and low prescribers. Diagnostic labelling was the best predictor for high prescribing. Current guidelines recommend considering antibiotic treatment for patients with co-morbidities. In our study, treating a large number of high-risk patients was not associated with high prescribing.

Medical overuse and quaternary prevention in primary care - A qualitative study with general practitioners.

BACKGROUND: Medical overuse is a topic of growing interest in health care systems and especially in primary care. It comprises both over investigation and overtreatment. Quaternary prevention strategies aim at protecting patients from unnecessary or harmful medicine. The objective of this study was to gain a deeper understanding of relevant aspects of medical overuse in primary care from the perspective of German general practitioners (GPs). We focused on the scope, consequences and drivers of medical overuse and strategies to reduce it (=quaternary prevention). METHODS: We used the qualitative Grounded Theory approach. Theoretical sampling was carried out to recruit GPs in Bavaria, Germany. We accessed the field of research through GPs with academic affiliation, recommendations by interview partners and personal contacts. They differed in terms of primary care experience, gender, region, work experience abroad, academic affiliation, type of specialist training, practice organisation and position. Qualitative in-depth face-to-face interviews with a semi-structured interview guide were conducted (n = 13). The interviews were audiotaped and transcribed verbatim. Data analysis was carried out using open and axial coding. RESULTS: GPs defined medical overuse as unnecessary investigations and treatment that lack patient benefit or bear the potential to cause harm. They observed that medical overuse takes place in all three German reimbursement categories: statutory health insurance, private insurance and individual health services (direct payment). GPs criticised the poor acceptance of gate-keeping in German primary care. They referred to a low-threshold referral policy and direct patient access to outpatient secondary care, leading to specialist treatment without clear medical indication. The GPs described various direct drivers of medical overuse within their direct area of influence. They also emphasised indirect drivers related to system or societal processes. The proposed strategies for reducing medical overuse included a well-founded wait-and-see approach, medical education, a trustful doctor-patient relationship, the improvement of primary/health care structures and the involvement of patients and society. CONCLUSIONS: GPs are frequently located at the starting point of the diagnostic and treatment process. They have the potential to play a vital role in quaternary prevention. This requires a debate going beyond the medical profession and involving society as a whole.

Missing risks in opportunistic screening for type 2 diabetes - CroDiabGP study.

Aim To examine two methods of extracting risks for undetected type 2 diabetes (T2D): derived from electronic medical record(EMR) and family medicine (FM) assessment during pre-consultation phase. All risks were structured in three lists of patients' data using Wonca International Classification Committee(WICC). Missing data were detected in each list. Methods A prospective study included a group of 1883 patients(aged 45-70) identified with risks. Risks were assessed based on EMR for continuity variables and FM's assessment for episodes of disease and personal related information. Patients were categorized with final diagnostic test in normoglycaemia, impaired fasting glycaemia and undetected T2D. Results Total prevalence of diabetes was 10.9% (new 1.4%), of which 59.3% were females; mean age was 57.4. The EMR risks were hypertension in 1274 patients (yes 67.6%, no 27.9%, missing 4.4%), hypolipemic treatment in 690 (yes 36.6%, no 30.9%, miss 32.5%). In the episodes of disease: gestational diabetes mellitus in 31 women (yes 2.8%, missing 97.2%). Personal information: family history of diabetes in 649 (yes 34.5%, no 12.4%, missing 53.1%), overweight in 1412 (yes 75.0%, no 8.4%, missing 16.6%), giving birth to babies >4000g in 11 women (yes 0.9%, missing 99.1%). Overweight alone was the best predictor for undiagnosed type 2 diabetes, OR: 2.11 (CI: 1.41-3.15) (p<.001). Conclusion Two methods of extraction could not detect data for episodes of the disease. In the list of personal information, FMs could not assess overweight for one in six patients and family history for every other patient. The study can stimulate improving coded and structured data in EMR.

Diuretics for hypertension--an inconsistency in primary care prescribing behaviour.

OBJECTIVE: Internationally there is an ongoing debate on diuretics as first-line therapy for most patients with hypertension. In spite of many arguments against them in antihypertensive monotherapy, the authors of the present study perceived them to be regularly prescribed in combination therapy in Germany. The study objective was to look for this discrepancy in prescribing reality as a contribution from clinical practice to an academic debate. METHODS: A descriptive cross-sectional study in a yearly contact group (YCG; 1.7.2007-31.06.2008) was conducted based on data from a scientific network of 22 general practitioners in Germany. All patients with hypertension as diagnosed by their general practitioner were included. Antihypertensives were grouped according to the ATC classification. To assess for potential design effects by the given two-level setting, 95% confidence intervals (CI) were adjusted for clustering. RESULTS: Hypertension had been diagnosed in 9.3% of the 58 852 patients. Of these, 21.6% received no antihypertensives. Of those who were treated, 30.6% (CI [28.6-32.6]) had monotherapy. In monotherapy, 8.6% (CI [7.1-10.2]) were prescribed some diuretic, 1.5% (CI [0.5-3.0]) received hydrochlorothiazide (HCT). Combination therapy was prescribed to 69.4% (CI [67.2-71.6]). These patients received some diuretic in 79.0% (CI [76.9-81.0]) of the cases, of which 80.8% (CI [78.5-83.1]) had a combination with HCT. HCT was prescribed in 76.2% (CI [73.5-78.9]) in fixed-dose formulations. CONCLUSION: In spite to the many arguments against them, leading to their almost complete disregard in monotherapy, thiazide-diuretics seem to be standard in combination therapy in Germany. This inconsistency can not be explained by the arguments of the current debate. Key limitations of the present study include the lack of ability to tell whether a given monotherapy is the first-line medication, the small sample size and the possible selection bias.

Antibiotic prescribing in general practice--the rhythm of the week: a cross-sectional study.

OBJECTIVES: Overprescribing of antibiotics in primary care is a worldwide phenomenon. Prescriptions can be used to reduce the uncertainty inherent in general practice. We assumed a heightened prescribing rate on Fridays because of more uncertainty before the pending weekend. METHODS: Cross-sectional study from a general practice research database with 102 140 patients of 32 practices in Germany. Prescribing rates of antibiotics on different days of the week were analysed. In order to evaluate the influence of the weekday within a multivariate setting, we used SAS PROC GENMOD. This procedure was parameterized accordingly to account for the cluster design of the study. RESULTS: The prescribing rate of antibiotics on Fridays was 23.3% higher than the average of the other days of the working week (6.04% versus 4.90%, P < 0.0001). The significance of this finding was confirmed by the multivariate analysis. CONCLUSIONS: There is periodic fluctuation of antibiotic prescribing rates over the week. This cannot be explained by morbidity itself. Factors beyond biomedical indication are well known to influence prescribing patterns. These factors should not only be further explored, but also acknowledged when trying to reduce overprescribing.

Diagnosing somatisation disorder (P75) in routine general practice using the International Classification of Primary Care.

OBJECTIVE: (i) To analyze general practitioners' diagnosis of somatisation disorder (P75) using the International Classification of Primary Care (ICPC)-2-E in routine general practice. (ii) To validate the distinctiveness of the ICD-10 to ICPC-2 conversion rule which maps ICD-10 dissociative/conversion disorder (F44) as well as half of the somatoform categories (F45.0-2) to P75 and codes the other half of these disorders (F45.3-9), including autonomic organ dysfunctions and pain syndromes, as symptom diagnoses plus a psychosocial code in a multiaxial manner. METHODS: Cross-sectional analysis of routine data from a German research database comprising the electronic patient records of 32 general practitioners from 22 practices. For each P75 patient, control subjects matched for age, gender, and practice were selected from the 2007 yearly contact group (YCG) without a P75 diagnosis using a propensity-score algorithm that resulted in eight controls per P75 patient. RESULTS: Of the 49,423 patients in the YCG, P75 was diagnosed in 0.6% (302) and F45.3-9 in 1.8% (883) of cases; overall, somatisation syndromes were diagnosed in 2.4% of patients. The P75 coding pattern coincided with typical characteristics of severe, persistent medically unexplained symptoms (MUS). F45.3-9 was found to indicate moderate MUS that otherwise showed little clinical difference from P75. Pain syndromes exhibited an unspecific coding pattern. Mild and moderate MUS were predominantly recorded as symptom diagnoses. Psychosocial codes were rarely documented. CONCLUSIONS: ICPC-2 P75 was mainly diagnosed in cases of severe MUS. Multiaxial coding appears to be too complicated for routine primary care. Instead of splitting P75 and F45.3-9 diagnoses, it is proposed that the whole MUS spectrum should be conceptualized as a continuum model comprising categorizations of uncomplicated (mild) and complicated (moderate and severe) courses. Psychosocial factors require more attention.

Factors associated with physical activity of patients with osteoarthritis of the lower limb.

OBJECTIVE: In patients with osteoarthritis (OA), moderate physical activity (PA) can reduce the progress of joint damage. PA is therefore an important target of in the non-surgical treatment of OA. To know about factors associated with PA can increase the success of interventions aiming at increasing PA. The aim of the study was to determine predictors of PA in patients suffering from OA to the hip or to the knee. METHODS: In total, 1250 outpatients from 75 general practices were consecutively approached, 1021 returned questionnaires containing sociodemographic data, and short forms of the International Physical Activity Questionnaire (IPAQ), the Arthritis Impact Measurement Scale and the Patient Health Questionnaire to assess concomitant depression. A hierarchical stepwise multiple linear regression analysis with the IPAQ continuous score as dependent variable was performed. RESULTS: Comparison of our findings with General population suggests that the overall PA of OA patients is decreased. Main predictors of PA were physical limitation to the lower body (beta = -0.179; P = 0.001), social contacts (P = -0.134; P < 0.001), pain (beta =-0.120; P = 0.001), age (beta = -0.110; P = 0.004) and the body mass index (beta =-0.043; P < 0.001). CONCLUSION: The findings emphasize the influence of physical as well as psychosocial factors on PA of patients with OA and should help to tailor future interventions more appropriately. Further research is needed to determine if these tailored interventions will result in better compliance and in increased PA.

Co- and multimorbidity patterns in primary care based on episodes of care: results from the German CONTENT project.

BACKGROUND: Due to technological progress and improvements in medical care and health policy the average age of patients in primary care is continuously growing. In equal measure, an increasing proportion of mostly elderly primary care patients presents with multiple coexisting medical conditions. To properly assess the current situation of co- and multimorbidity, valid scientific data based on an appropriate data structure are indispensable. CONTENT (CONTinuous morbidity registration Epidemiologic NeTwork) is an ambitious project in Germany to establish a system for adequate record keeping and analysis in primary care based on episodes of care. An episode is defined as health problem from its first presentation by a patient to a doctor until the completion of the last encounter for it. The study aims to describe co- and multimorbidity as well as health care utilization based on episodes of care for the study population of the first participating general practices. METHODS: The analyses were based on a total of 39,699 patients in a yearly contact group (YCG) out of 17 general practices in Germany for which data entry based on episodes of care using the International Classification of Primary Care (ICPC) was performed between 1.1.2006 and 31.12.2006. In order to model the relationship between the explanatory variables (age, gender, number of chronic conditions) and the response variables of interest (number of different prescriptions, number of referrals, number of encounters) that were applied to measure health care utilization, we used multiple linear regression. RESULTS: In comparison to gender, patients' age had a manifestly stronger impact on the number of different prescriptions, the number of referrals and number of encounters. In comparison to age (beta = 0.043, p < 0.0001), multimorbidity measured by the number of patients' chronic conditions (beta = 0.51, p < 0.0001) had a manifestly stronger impact the number of encounters for the observation period. Moreover, we could observe that the number of patients' chronic conditions had a significant impact on the number of different prescriptions (beta = 0.226, p < 0.0001) as well as on the number of referrals (beta = 0.3, p < 0.0001). CONCLUSION: Documentation in primary care on the basis of episodes of care facilitates an insight to concurrently existing health problems and related medical procedures. Therefore, the resulting data provide a basis to obtain co- and multimorbidity patterns and corresponding health care utilization issues in order to understand the particular complex needs caused by multimorbidity.

Osteoarthritis and functional disability: results of a cross sectional study among primary care patients in Germany.

BACKGROUND: The aim of the study was to determine factors associated with functional disability in patients with OA. METHODS: 1250 questionnaires were distributed to OA outpatients from 75 general practices; 1021 (81.6%) were returned. Questionnaires included sociodemographic data, the short form of the Arthritis Impact Measurement Scale (AIMS2-SF), and the Patient Health Questionnaire (PHQ-9) to assess concomitant depression. A hierarchical stepwise multiple regression analysis with the AIMS2-SF dimension "lower body" as dependent was performed. RESULTS: Main factors associated with functional disability were depression symptoms, as reflected in a high score of the PHQ-9 (beta = 0.446; p < 0.0009), pain as reflected in the AIMS2-SF symptom scale (beta = 0.412; p = 0.001), and few social contacts (beta = 0.201; p < 0.042). A high body mass index was associated with lower functional ability (beta = 0.332; p = 0.005) whereas a higher educational level (beta = -0.279; p = 0.029) predicted less impairment. Increased age was a weak predictor (beta = 0.178; p = 0.001) of disability. With a p of 0.062 the radiological severity according to the grading of Kellgren and Lawrence slightly surpassed the required significance level for remaining in the final regression model. CONCLUSION: The results emphasize that psychological as well as physical factors need to be addressed similarly to improve functional ability of patients suffering from OA. More research with multifaceted and tailored interventions is needed to determine how these factors can be targeted appropriately.

Osteoarthritis of the knee and hip: a comparison of factors associated with physical activity.

To assess factors associated with physical activity (PA) in a large sample of primary care patients, 1,250 outpatients from 75 general practices were approached consecutively. Of these, 1,021 (81.7%) returned short forms of the international physical activity questionnaire (IPAQ) and the arthritis impact measurement scale (AIMS2-SF). In addition, the patient health questionnaire (PHQ-9) was used to assess concomitant depression. A stepwise multiple linear regression analysis with the IPAQ score as dependent variable was performed separately for knee and hip patients. The impact of osteoarthritis (OA) on patients with an affected knee (594/58.2%) was more severe, as reflected in higher scores in the "symptom", "lower body", and "affect" scales of the AIMS2-SF (p < 0.01 for all). These patients were also less active than patients with OA to the hip (p = 0.02 for IPAQ score). Main predictors of PA [change in p(F) for all factors < or =0.001] in knee OA patients were physical limitation to the lower limb (R(2) = 0.180), social network (R(2) = 0.121), pain (R(2) = 0.111), body mass index (R(2) = 0.041), and age (R(2) = 0.032). Predictors for OA at the hip (427/41.8%) differed slightly [change in p(F) for all factors < or =0.003): physical limitation to the lower limb (R(2) = 0.162), pain (R(2) = 0.131), PHQ-9 score (R(2) = 0.092), social network (R(2) = 0.078), and disease duration (R(2) = 0.043). Our findings suggest that factors associated with PA differ depending on the localization of the OA. Our results may help to tailor future interventions more appropriately. Further research is needed to determine whether these tailored interventions will result in increased PA.
