RESUMEN
To assess the significance of initial empiric parenteral antibiotic therapy in patients requiring surgery for community-acquired secondary peritonitis, 425 patients hospitalized between January 1999 and September 2001 in 20 clinics across Germany were followed for a total of 6,521 patient days. Perforated appendix (38%), colon (27%), or gastroduodenum (22%) were the most common sites of infection. Escherichia coli was the most common pathogen. A total of 54 (13%) patients received inappropriate initial parenteral therapy not covering all bacteria isolated, or not covering both aerobes and anaerobes in the absence of culture results. Clinical success, predefined as the infection resolving with initial or step-down therapy after primary surgery, was achieved in 322 patients (75.7%; 95% confidence interval (CI), 70.6-81.2). Patients were more likely to have clinical success if initial antibiotic therapy was appropriate (78.6%; 95% CI, 73.6-83.9) rather than inappropriate (53.4%; 95% CI, 41.1-69.3). Patients having clinical success were estimated to stay 13.9 days in hospital (95% CI, 13.1-14.7), while those who had clinical failure stayed 19.8 days (95% CI, 17.3-22.3). In conclusion, appropriateness of initial parenteral antibiotic therapy was a predictor of clinical success, which in turn was associated with length of stay.

We estimate the extent to which recommendations on the prevention and treatment of migraine issued by professional medical bodies are implemented in medical practice in Germany. Computerized data (MediPlus, IMS Health) were analyzed in 4,636 male and 16,573 female migraineurs from 383 primary care practices 1994 through 1996 (Primary Care of Migraine, PCAOM study). A total of 90,540 drug prescriptions with a documented diagnosis of migraine were issued in 45,669 person-years (1,492 prescriptions [DM 40.99] per person-year to men, 2,109 prescriptions [DM 62.01] per person-year to women). Approximately three of every four prescriptions were incompatible with the recommendations of the German Migraine and Headache Society (DMKG), amounting to extrapolated costs of DM 49 million per year borne by the German statutory health insurance fund for combination migraine preparations. The density of non-DMKG therapies for diagnosed migraine followed a sigmoid curve with increasing patient age, while DMKG-compliant therapies described a bell-shaped curve. Referrals to neurological care specialists were not associated with subsequent primary care focus on recommended therapies. We conclude that medication prescribed for migraine is largely not according to long-standing recommendations by medical societies in Germany.
