Frequency distribution of health disorders in primary care-its consistency and meaning for diagnostics and nomenclature.

RN Braun observed that frequencies of health disorders in general practice are so consistent that he called his discovery "Case Distribution Law". Our study compares morbidity data from methodologically similar surveys in primary care practices over a period of fifty years. Frequency ranks were determined for each observation period and the first 150 ranks were compared with Spearman's correlation coefficients. All correlations were consistently positive. Frequency ranks were strikingly similar for surveys carried out at approximately the same time, especially when nomenclatural matching had been carried out before data collection. Ranks were also very similar where clear disease classifications were possible, but less so for non-specific symptoms.The consistency of the distribution of health disorders helps develop diagnostic strategies (diagnostic protocols) and appropriate labeling for non-specific, diagnostically open symptom classifications. According to Braun's considerations, the regularity of case distribution plays an important role in the professionalization of primary care.

Diagnostic protocols-A consultation tool still to be discovered.

RATIONALE: Experienced primary care physicians handle most illnesses to everyone's satisfaction despite limited resources of time and means. However, cases can be multifaceted in that harmless-presenting symptoms may also be warning signals or an indicator of a health disorder that too infrequently presents in family practice to be diagnosed correctly. On the basis of these observations, RN Braun developed 82 diagnostic protocols for a structured recording of various complaints. METHOD: All consultations during the years 2001 to 2014, in which 1 author (WF) had used diagnostic protocols in her single-handed practice, were analyzed retrospectively regarding reasons for encounter, diagnostic classification, and long-term outcome. RESULTS: During the period, a diagnostic protocol was used 1686 times. It was applied at a rate of approximately 5% of 2500 new complaints annually, most often (1366 times) for febrile conditions. In 320 consultations for other complaints, 43 different diagnostic protocols were applied. Among them, the "tabula diagnostica" for various undifferentiated symptoms was used most frequently (n = 54), followed by diagnostic protocols for headache (n = 45), dizziness (n = 36), precordial pain (n = 20), nonspecific abdominal pain (n = 15), low back pain (n = 14), hypertension (n = 12), diarrhea > 1 week (n = 12), epigastralgia (n = 11), depression (n = 10), polyarthralgia (n = 8), cough, and lower abdominal pain (each n = 7). A final diagnosis was established in less than 20% of cases. CONCLUSIONS: This observational study from routine practice gives an insight how diagnostic protocols helped to manage complex patient presentations. A broader use of diagnostic protocols could investigate the potential of this consultation tool to handle the complexity of primary health care. The use of a standardized diagnostic approach could stimulate research, in particular on managing common complaints/undifferentiated illness and their inherent diagnostic uncertainty.

[Metaphor and narrative as instruments for identity development among general practitioners? A qualitative study of a 240-hour course]. / Metapher und Narrativ als Instrumente allgemeinmedizinischer Identitätsbildung? Eine qualitative Studie aus dem 240-Stunden-Kurs.

Focusing on case presentation in GPs' training programmes did not confirm the high expectations of "narrative based medicine" concerning the linguistic categories of 'metaphor' and 'narrative' as central instruments for the promotion of the professional identity of young general practitioners. Quantitative evaluation control showed that traditional Balint-group work was highly estimated throughout the whole course programme against all other items followed by case presentations. These results indicate that integration of the narrative-based approach into Balint group work might be possible, but moreover they suggest the possibility of a narrative-based qualitative evaluation of the training group's interactions and processes, which until now has been used far too seldom.
