What patients really think about asthma guidelines: barriers to guideline implementation from the patients' perspective.

BACKGROUND: Treatment of asthma does not always comply with asthma guidelines (AG). This may be rooted in direct or indirect resistance on the doctors' and/or patients' side or be caused by the healthcare system. To assess whether patients' concepts and attitudes are really an implementation barrier for AG, we analysed the patients' perspective of a "good asthma therapy" and contrasted their wishes with current recommendations. METHODS: Using a qualitative exploratory design, topic centred focus group (FG) discussions were performed until theoretical saturation was reached. Inclusion criteria were an asthma diagnosis and age above 18. FG sessions were recorded audio-visually and analysed via a mapping technique and content analysis performed according to Mayring (supported by MAXQDA®). Participants' speech times and the proportion of time devoted to different themes were calculated using the Videograph System® and related to the content analysis. RESULTS: Thirteen men and 24 women aged between 20 and 77 from rural and urban areas attended five FG. Some patients had been recently diagnosed with asthma, others years previously or in childhood. The following topics were addressed: (a) concern about or rejection of therapy components, particularly corticosteroids, which sometimes resulted in autonomous uncommunicated medication changes, (b) lack of time or money for optimal treatment, (c) insufficient involvement in therapy choices and (d) a desire for greater empowerment, (e) suboptimal communication between healthcare professionals and (f) difficulties with recommendations conflicting with daily life. Primarily, (g) participants wanted more time with doctors to discuss difficulties and (h) all aspects of living with an impairing condition. CONCLUSIONS: We identified some important patient driven barriers to implementing AG recommendations. In order to advance AG implementation and improve asthma treatment, the patients' perspective needs to be considered before drafting new versions of AG. These issues should be addressed at the planning stage. TRIAL REGISTRATION: DRKS00000562 (German Clinical Trials Registry).

[The use of benzodiazepines and Z-drugs for patients with sleeping problems - A survey among hospital doctors and nurses]. / Benzodiazepine und Z-Substanzen als Schlaf- und Beruhigungsmittel in einem Krankenhaus.

Aim | Benzodiazepines and Z-drugs are frequently prescribed sleep medications in spite of their poor risk-benefit ratio when used over a longer period of time. The aim of the study was to find out how the medical and nursing staff in a general hospital estimated the frequency of use for these drugs, and the risk-benefit ratio for elderly patients as well as the factors which positively influence the perceived use of these drugs. Methods | All members of the medical and nursing staff of a hospital received a questionnaire about their use of, and attitudes towards, benzodiazepines and Z-drugs. Absolute and relative frequencies were calculated to estimate the perceived frequency of use and the risk-benefit ratio. Multiple logistic regressions were used to analyze which factors are associated with a perceived high use of benzodiazepines or Z-drugs for insomnia. Results | More nurses than hospital doctors believed that they dispensed benzodiazepines often or always (57 % vs. 29 %) to patients with insomnia; this was also the case for Z-drugs (66 % vs. 29 %). Nearly half of the hospital doctors and 29 % of the nurses perceived more harms than benefits for benzodiazepines in the elderly. The following factors were associated with a high perceived usage of Z-drugs: working as a nurse (OR: 13,95; 95%-CI: 3,87-50,28), working in a non-surgical department (5,41; 2,00-14,61), having < 5 years of professional experience (4,90; 1,43-16,81) and feeling that the benefits of Z-drugs outweigh the risks for elderly patients (5,07; 1,48-17,35). For benzodiazepines, only the perceived positive risk-benefit ratio had an influence on the perceived use (3,35; 1,28-8.79). Conclusion | The medical and nursing staff perceived the frequency of prescription of benzodiazepines and Z-drugs and the risk-benefit ratio in different ways. Other aspects, such as working in a non-surgical department or having a smaller amount of working experience may also influence the decision to use Z-drugs.

[The Preventive Home Visit as a Preventive Intervention to Reach the Elderly--Effectiveness and Cost-Effectiveness of Different Ways of Approach]. / Der präventive Hausbesuch als zugehende Präventionsmaßnahme im Alter--Effektivität und Kosteneffektivität von Zugangswegen.

The aim of the study was a systematical further development of targeted approaches. Research questions were how elderly women and men could be motivated to participate in a preventive intervention and by which approaches elderly with different health risks could be reached. In several stages a specific motivational material was developed. Afterwards two different approaches to the elderly (general practice, health insurance) were tested and evaluated considering its (cost) effectiveness.

Background paper to the recommendation for routine rotavirus vaccination of infants in Germany.

Two rotavirus (RV) vaccines were introduced to the European market in 2006. To support the decision-making process of the German Standing Committee on Vaccination ("Ständige Impfkommission", STIKO) regarding adoption of routine RV vaccination into the national vaccination schedule in Germany relevant scientific background was reviewed. According to STIKO's Standard Operating Procedures for the development of evidence-based vaccination recommendations, a set of key questions was addressed and systematic reviews were performed with a focus on the efficacy, effectiveness, impact and safety of RV vaccines. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology was applied to assess the quality of available evidence. Data from 5 randomized controlled trials demonstrated a high efficacy of RV vaccines in preventing severe RV-associated gastroenteritis (91%) and hospitalization (92%) in settings comparable to Germany. Post-marketing observational studies confirmed these findings. In several countries, impact studies suggest that age groups not eligible for vaccination might also benefit from herd effects and demonstrated a decrease in the number of nosocomial RV infections after RV vaccine introduction. The vaccines were considered safe, except for a slightly increased risk of intussusception shortly after the first dose, corresponding to 1-2 additional cases per 100,000 infants vaccinated (relative risk =1.21, 95% confidence interval [CI] 0.68-2.14). RV case-fatality is extremely low in Germany. However, RV incidence among children aged <5 years is high (reported 8-14 cases per 1000 children annually), and of these almost half require hositalization. In view of the available evidence and expected benefits, STIKO recommends routine rotavirus vaccination of children under the age of 6 months with the main goal of preventing RV-associated hospitalizations in Germany, especially among infants and young children.

[Asthma guidelines: knowledge of family doctors and trainees in Germany]. / Wissen von Hausärzten und Ärzten in Weiterbildung über nationale Asthmaleitlinien.

In Germany as well as internationally, evidence-based asthma guidelines were developed as a decision aid for diagnosis and therapy. However, adherence to recommendations is usually less than optimal. The authors explore potential implementation barriers: knowledge gaps, practical presentation of guidelines, and attitudes of doctors and patients. In this paper, we compare results of our knowledge survey of family doctors and trainees with results of similar national and international studies. In all studies, all surveyed groups of physicians revealed considerable knowledge gaps. Many physicians in our own study erroneously preferred mucolytics and antibiotics to treat acute or subacute asthma symptoms though these drugs are not or only exceptionally indicated. The inflammatory character of asthma often goes unrecognized, as well as the importance of inhaled (and systemic) corticosteroids in long term treatment (or treatment of exacerbations).

[Use and acceptance of a basic geriatric assessment in primary care setting]. / Das geriatrische Basisassessment in der Hausarztpraxis.

BACKGROUND: Aim of this study was to evaluate the acceptance and use of a basic geriatric assessment (BGA), as it is covered by the German pay system, in primary care practices. METHODS: We conducted qualitative interviews and collected quantitative data by an online questionnaire. RESULTS: A total of 17 (10 men) general practitioners (GPs) agreed to be interviewed; 161 patients (134 men) completed the online questionnaire. GPs mainly performed BGA to substantiate the suspicion of cognitive impairment. Most of the German general practices accomplished not more than 5-10 BGA per quarter. Although those GPs who conducted BGA were convinced of its usefulness with regard to further patient care, concrete interventions were rarely named. The tests used within the BGA were not always in line with recommendations from the specific guidelines. The main reasons not to conduct BGA were the amount of time required and the lack of therapeutic consequences. CONCLUSION: Hitherto BGA is not an established tool in German primary care practices. The question, which single instruments are most suitable for older general practice patients, still needs clarification.

[National S3 guideline on uncomplicated urinary tract infection: recommendations for treatment and management of uncomplicated community-acquired bacterial urinary tract infections in adult patients]. / Nationale S3-Leitlinie "Unkomplizierte Harnwegsinfektionen" : Empfehlungen zu Therapie und Management unkomplizierter bakterieller ambulant erworbener Harnwegsinfektionen bei erwachsenen Patienten.

BACKGROUND: Urinary tract infections (UTI) belong to the most frequent bacterial infections in outpatients. Increasing antibiotic resistance rates and a new appreciation of the epidemiological side effects of antibiotics ("collateral damage") have warranted an update of the guidelines on uncomplicated UTI as an S3 clinical guideline. METHODS: The guideline was developed by the Deutsche Gesellschaft für Urologie (DGU) in collaboration with the Deutsche Gesellschaft für Allgemein- und Familienmedizin (DEGAM), Deutsche Gesellschaft für Gynäkologie und Geburtshilfe (DGGG), Deutsche Gesellschaft für Hygiene und Mikrobiologie (DGHM), Deutsche Gesellschaft für Infektiologie (DGI), Deutsche Gesellschaft für Nephrologie (DGfN), Paul-Ehrlich-Gesellschaft für Chemotherapie (PEG) and a patient representative. The systematic review of the literature on the topics of the guideline was performed for the time period of 1 January 1998 to 30 April 2008 in the databases of the Cochrane Library and MEDLINE. International guidelines of the years 1999-2007 were included. RESULTS: Uncomplicated UTI comprise uncomplicated cystitis and uncomplicated pyelonephritis. The leading uropathogen is Escherichia coli. The choice of the antibiotic substance follows the five primary aspects: (1) individual patient risk and antibiotic pretreatment; (2) bacterial spectrum and antibiotic susceptibility; (3) effectivity of the antimicrobial substance demonstrated in clinical studies; (4) epidemiological effects ("collateral damage"); and (5) adverse effects. If antibiotics such as trimethoprim/sulfamethoxazole or fluoroquinolones have previously been given, the risk for pathogens to become resistant against these substances is increased. Because of increasing resistance rates of E. coli against trimethoprim/sulfamethoxazole also in uncomplicated UTI, trimethoprim alone or in combination with sulfamethoxazole is no longer regarded as the first-line agent in the empiric treatment of uncomplicated cystitis, unless the regional resistance rate is below 20%. The antibiotic resistance rates of fluoroquinolones in uncomplicated UTI are still below 10% in Germany, but there is a significant emergence of resistance compared to earlier years. Moreover, fluoroquinolones and group 3 cephalosporins exhibit negative epidemiological effects resulting in selection of multi-resistant pathogens. Because these antibiotic classes are needed in therapy of life-threatening infections, such effects should be taken seriously. For substances like fosfomycin, nitrofurantoin or mecillinam"collateral damage" has not been documented or only to a lesser degree. Therefore, for empiric therapy of frequent uncomplicated cystitis fosfomycin-trometamol, nitrofurantoin or pivmecillinam (not listed in Germany) are recommended as first-line antibiotics. For oral first-line treatment of uncomplicated pyelonephritis, fluoroquinolones are still recommended in sufficiently high dosage due to the resistance rates of E. coli still being below 10% and the superior effectivity compared to other antibiotics. Asymptomatic bacteriuria (ASB) should only be treated in exceptional cases such as pregnant women or prior to expected mucocutaneous traumatising interventions of the urinary tract. CONCLUSION: The S3 guideline on uncomplicated urinary tract infections is a comprehensive set of evidence- and consensus-based recommendations dealing with epidemiology, diagnosis, therapy and management of uncomplicated bacterial UTI of adult outpatients. A broad implementation in all disciplines taking care of patients with UTI is necessary in order to ensure a prudent antibiotic policy in these frequent infections and thus improve patient care.

[Prerequisites for a new health care model for elderly people with multiple morbidities: results and conclusions from 3 years of research in the PRISCUS consortium]. / Voraussetzungen für ein neues Versorgungsmodell für ältere Menschen mit Multimorbidität: Ergebnisse und Schlussfolgerungen aus 3-jähriger Forschung im PRISCUS-Verbund.

BACKGROUND: The concurrent presence or manifestation of multiple chronic conditions, i.e. multimorbidity, poses a challenge to affected patients and their relatives, physicians, and practitioners, and to the health care system in general. Aiming to improve medical care for different chronic diseases, the Chronic Care Model also appears to be suited for multimorbidity. The established research consortium PRISCUS is trying to create some of the prerequisites for a new care model for multimorbid, elderly patients oriented along the lines of the Chronic Care Model. METHODS AND RESULTS: Four out of seven subprojects of the research consortium provide an overview of some of their findings. Topics in a sports medicine subproject were the assessment of physical activity by means of a newly developed questionnaire and the development and feasibility testing of an exercise program for elderly people with chronic conditions and mobility impairment. Partners from family medicine implemented geriatric assessment in a primary care setting and evaluated its consequences. In a pharmacological subproject, potentially inappropriate medication as well as drug-drug interactions and dosing errors were addressed. The health economic subproject investigated quality of life impairment due to multiple chronic diseases and the effects of multimorbidity on costs. CONCLUSIONS: The results of the PRISCUS research consortium allow a better description of consequences of multimorbidity and illustrate at least some new approaches towards prevention, diagnosis, and treatment of patients suffering from multimorbidity. Ongoing projects will test the efficacy of a physical activity program and a new complex intervention to reduce potentially inappropriate medication in the elderly. With this, the research consortium will create some prerequisites for a new health care model for patients with multimorbidity comparable to the Chronic Care Model.

[PrefCheck: patient-centered treatment planning with older multimorbid patients. Method and design]. / PräfCheck: Patientenzentrierte Behandlungsplanung mit älteren multimorbiden Patienten. Methodik und Design.

BACKGROUND: The aim of the study is to develop and test a consultation guide (PrefCheck) for general practitioners (GPs) based on geriatric assessment results. The goal of the consultation guide is to facilitate priority setting and treatment planning based on building a partnership with geriatric patients with multiple chronic diseases. METHODS AND AIMS: The mixed method study consists of three complementary parts: (A) health and treatment priorities of 32 patients and their 8 GPs are determined and explored on the basis of assessment results. These findings lead to the development of the consultation guide, which is subsequently tested in a cluster-randomized controlled intervention study (B) with 40 GPs and 320 patients. The aim of this study is to assess whether PrefCheck results in improved agreement in the number of health and treatment priorities between patients and their doctors. The study concludes with an evaluation study (C) with 5 GPs and 15 patients. CONCLUSIONS: Results will be presented in a future publication. In particular it will be demonstrated whether the consultation guide can strengthen the position of older patients in the doctor-patient relationship, increase the level of information on both sides, and contribute to a shared and holistic treatment planning.

[Influenza vaccination by Lower Saxonian general practitioners - a secondary analysis of physicians' data from 1995/1996, 2002/2003, and 2005/2006]. / Influenza-Impfungen durch Niedersächsische Hausärzte - eine Sekundäranalyse vertragsärztlicher Versorgungsdaten aus 1995/1996, 2002/2003 und 2005/2006.

Vaccination against infection with human influenza virus is considered to be one of the most effective preventive measures available, especially when complications such as hospitalisation or death and indirect costs from off-work are considered. General practice is the preferable place for annual influenza vaccination because here the elderly and those endangered from bad health conditions are cared for frequently and regularly. The aim of this study was to find out the frequencies of influenza vaccination by Lower Saxonian contract physicians during three time periods with special respect to patients of older age or at risk. Data from two sources of health-care service have been analysed, namely from the contract physicians' union of Lower Saxony with all physicians vaccinating against influenza in the winter seasons of 1995/1996, 2002/2003, and 2005/2006, and from direct access to the electronic practice record system of 79 general practices via the BDT software data interface. Contract physicians, of whom more than 90 % are general practitioners, from Lower Saxony, vaccinate patients of the statutory health insurance against influenza in markedly increasing numbers, since 1995/1996 and 2002/2003 up to 2005/2006. Those over sixty years old or at high risk from bad health conditions are vaccinated up to seven-fold more frequently, compared to other patients. Influenza vaccination coverage rates (VCRs) are significantly higher in small and in medium-sized practices, compared to those with many patients. Nevertheless, influenza VCRs in Lower Saxony are not yet as high as would be necessary or desirable when compared internationally. Secondary analysis of aggregated health service data revealed inconsistencies in the primary material on cross-checking and validating, probably being caused during the external process of data aggregation and anonymisation. Also major systematic obstacles were found in the subsequent process of analysis. Nevertheless, fundamental results have been produced and are valid for all statutory health insured Lower Saxonians. Data from direct access to electronic practice records allowed for a deeper and multi-faceted insight into 101 928 patients of the same population, limited by the possibility of selection bias ('convenience sample'). Secondary analysis of health service data from different sources and their cross-check comparison is possible and successful. It is important to inform and involve the holder of the primary data extensively, following the guide lines of "good practice secondary data analysis".

Priorities of elderly dizzy patients in general practice. Findings and psychometric properties of the"Dizziness Needs Assessment" (DiNA).

BACKGROUND: Dizziness as a geriatric syndrome needs to be assessed using a multi-dimensional, patient-centred approach in addition to a disease-orientated strategy. The aim of the study was to determine the priorities of elderly patients by a specific needs questionnaire, the"Dizziness Needs Assessment" (DiNA), and to evaluate its psychometric properties. METHODS: General practitioners (GPs) distributed questionnaires containing the DiNA as well as the Patients' Intentions Questionnaire (PIQ) to patients aged at least 65 years and suffering from dizziness. Items of both questionnaires were analysed by frequencies, means and rank correlations. Factor structure was explored by principal component analysis. RESULTS: A total of n=123 patients (mean age 76 years, 73% women) had suffered from dizziness on average for more than 3 years (57% chronic, i.e. >6 months). Knowing the cause of the dizziness was rated as very important by patients, and about half of them wished that their doctor would make more effort to investigate this. Among other differences, chronically dizzy patients ranked the risk of falling significantly higher than those with acute dizziness. Factor analysis revealed four subscales: "handicap and mobility" showed a very good reliability of 0.77 (Cronbach's α), indicating a "trait", whereas the other subscales rather indicated "state" characteristics. Validation coefficients showed that PIQ assesses general patient needs compared to the more specific dizziness-related needs revealed by the DiNA. CONCLUSION: The DiNA proved to be a valuable instrument to assess the specific priorities of elderly patients suffering from dizziness. Regarding the limited therapy options for dizziness in old age, a doctor-guided shift of patients' attention from causes to symptom-related implications could be a promising approach.

Procalcitonin guidance and reduction of antibiotic use in acute respiratory tract infection.

Increasing worldwide development of antimicrobial resistance and the association of resistance development and antibiotic overuse make it necessary to seek strategies for safely reducing antibiotic use and selection pressure. In a first step, in a non-interventional study, the antibiotic prescription rates, initial procalcitonin (PCT) levels and outcome of 702 patients presenting with acute respiratory infection at 45 primary care physicians were observed. The second part was a randomised controlled non-inferiority trial comparing standard care with PCT-guided antimicrobial treatment in 550 patients in the same setting. Antibiotics were recommended at a PCT threshold of 0.25 ng·mL(-1). Clinical overruling was permitted. The primary end-point for non-inferiority was number of days with significant health impairment after 14 days. Antibiotics were prescribed in 30.3% of enrolled patients in the non-interventional study. In the interventional study, 36.7% of patients in the control group received antibiotics as compared to 21.5% in the PCT-guided group (41.6% reduction). In the modified intention-to-treat analysis, the numbers of days with significant health impairment were similar (mean 9.04 versus 9.00 for PCT-guided and control group, respectively; difference 0.04; 95% confidence interval -0.73-0.81). This was also true after adjusting for the most important confounders. In the PCT group, advice was overruled in 36 cases. There was no significant difference in primary end-point when comparing the PCT group treated as advised, the overruled PCT group and the control group (9.008 versus 9.250 versus 9.000 days; p = 0.9605). A simple one-point PCT measurement for guiding decisions on antibiotic treatment is non-inferior to standard treatment in terms of safety, and effectively reduced the antibiotic treatment rate by 41.6%.

[Implementation of recommendations for the diagnosis of heart failure. [corrected]]. / Umsetzung von diagnostischen Empfehlungen bei Herzinsuffizienz.

BACKGROUND: National and international guidelines for the management of congestive heart failure (HF) suggest a variety of procedures for establishing its diagnosis and monitoring its course. The aim of this cross-sectional study was to investigate which of these recommendations were actually implemented and documented in the setting of general medical practice. METHODS: Patients receiving at least one cardiovascular drug (World health [WHO] anatomical chemical classification [ATC] class C) were identified from electronic medical records from 5 general practices from 1.4.2001 to 1.10.2004. Those patients with the documented diagnosis of HF were selected. All patients' records were reviewed and those diagnostic procedures and clinical findings were recorded on a standardized data extraction form that had been used to establish the diagnosis of HF. RESULTS: An electrocardiogram had been documented or retrieved in the chart in 41.2% of a total of 829 patients, an chest X-ray in 28.2%, an echocardiogram in 17.2%, and a cardiac catheterization performed in 1.8%. Serum natriuretic peptides were never recorded. Additionally the following symptoms and clinical signs were extracted from the paper chart: ankle edema (39.3%), exertional dyspnea (22.7%), rales (21.5%), cardiomegaly (19.0%), paroxysmal dyspnea (16.6%), pleural effusions (9.2%), tachycardia (6.7%) and acute pulmonary edema, hepatomegaly, nocturnal cough or jugular venous distension in fewer than 5%. CONCLUSION: Only a few of those clinical signs and diagnostic procedures recommended by guidelines for diagnosing HF were recorded in general practice. The reasons for this finding remain unclear. Even under the assumption that not all observed clinical signs and diagnostic procedures were documented, these findings reflect the actual diagnostic strategy in daily practice. The observed discrepancy between guideline recommendation and reality in everyday practice deserve attention. On the one hand, there is a need for improving the diagnostic approach to HF; on the other, guidelines need to set priorities of the recommendations for diagnosing HF.

Prevalence and predictors of polypharmacy among older primary care patients in Germany.

BACKGROUND: Older people consume an increasing amount of medication. Polypharmacy is associated with an elevated risk of adverse health outcomes resulting in hospitalizations and sometimes death. OBJECTIVES: To describe the prevalence of prescribed and over-the-counter (OTC) medications among older general practice patients living in the community. To determine predictors of polypharmacy (five or more prescribed drugs) from a variety of patient- and doctor-related factors. METHODS: Sixty-seven randomly selected practices in two areas of Germany and 466 of their older patients (70+ years) were recruited for a geriatric assessment study. A cross-sectional analysis of health problems, GPs' awareness and their interventions was conducted. In this post hoc analysis, we assessed the medication use as reported by older patients and compared it with doctors' perceived medication regimens for their respective patients. The detailed assessment of patients' health and well-being enabled us to explore a variety of predictors of polypharmacy using logistic regression analysis with forward selection. RESULTS: Study participants consumed an average of 3.7 prescribed medicines and an additional 1.4 OTC drugs. In all, 26.7% of patients used five and more chronically prescribed drugs. A set of five determinants predicted polypharmacy best: breathlessness, hypertension, dependency on instrumental activities of daily living, low subjective health and medication disagreement between doctors and patients. CONCLUSION: This older general practice population in Germany is among the top pharmaceutical user group of European study samples. Apart from disease-specific determinants, GPs should be aware that low subjective health and medication disagreement are independent predictors of polypharmacy.

[Home visits in German general practice: findings from routinely collected computer data of 158,000 patients]. / Hausbesuche: Versorgungsforschung mit hausärztlichen Routinedaten von 158.000 Patienten.

INTRODUCTION: Home visits are an integral part of general practice. However, information on this subject is lacking in Germany. Therefore we aim to describe the quantity of home visits, the target population and the workload for general practitioners on the basis of computerised data routinely collected in general practices. METHODS: The routine care data originate from 136 practices of the areas of Göttingen and Freiburg. Electronic patient records provided billing codes for home visits and consultations, patients' anonymous identification number, age, gender and ICD codes. RESULTS: 84 practices with complete datasets of 158,383 patients were available for the cross-sectional analysis in 2002. 12% of all patients required at least one home visit - significantly more elderly and female patients. Half of all patients visited at home requested one visit, whereas nearly 5% needed at least fortnightly visits throughout the year. 2/3 of all visited patients received an emergency visit. The quantity and nature of diseases also influenced home visit status. The workload of an average practice contained 9 visits per 100 consultations. 15 practices provided datasets between 1997 and 2001. In this period the total number of home visits declined. Within the same period, the target group has increasingly been restricted to old patients. CONCLUSION: Old age, female gender, quantity and nature of diseases positively influence home visit status. Compared to general practices in other European countries, the workload caused by house calls seems high in this German sample. Over recent years the frequency of home visits has decreased. In view of the demographic changes, decisions will have to be made as to who will care for the growing numbers of old patients requiring home visits.

[Health services research in general practice. A new approach]. / Medizinische Versorgung in der hausärztlichen Praxis. Ein neuer Forschungsansatz.

Competence networks in medicine, involving departments of general practice (www.kompetenznetze-medizin.de), as well as a large research support program "General Practice" funded by the German Federal Ministry of Education and Research (www.gesundheitsforschung-bmbf.de/de/439.php) mirror the increasing importance of academic general practice for health services research. The use and benefit of computerized medical records is exemplified by the classification of therapeutic measures and prevalence estimates of diseases. Computerized medical records from 134 practices could be extracted via the BDT (BehandlungsDatenTräger) interface. Using SQL (structured query language) queries, we identified patients with urinary tract infection (UTI), airway obstruction and chronic heart failure and the therapeutic management for these illnesses. Age and sex of the patients were nearly completely documented in the BDT data. Patients with UTI (6,239 consultations) received most often cotrimoxazole (69%) and fluoroquinolone (15%), less often trimethoprim (9%) and herbal UTI drugs (4%). About half of the 2,714 patients with asthma received inhaled steroids, to a somewhat lesser degree than patients suffering from chronic obstructive pulmonary disease (50 vs 53%). In a subsample of practices (n=44), we identified 4,120 patients with a diagnosis of chronic heart failure. Using refined analysis tools, computerized medical records from general practices may be helpful to answer relevant questions of health services research and contribute to quality assurance in ambulatory patient care.
