RESUMEN
BACKGROUND: Pharyngitis due to Group A beta-hemolytic streptococci (GAS) is seen as the main indication for antibiotics for sore throat. In primary care settings prescription rates are much higher than the prevalence of GAS. Recommendations in international guidelines differ considerably. A German guideline suggested to consider antibiotics for patients with Centor or McIsaac scores ≥ 3, first choice being penicillin V for 7 days, and recommended analgesics for all. We investigated, if the implementation of this guideline lowers the antibiotic prescription rate, and if a rapid antigen detection strep-test (RADT) in patients with scores ≥ 3 lowers the rate further. METHODS: HALS was an open pragmatic parallel group three-arm cluster-randomized controlled trial. Primary care practices in Northern Germany were randomized into three groups: Guideline (GL-group), modified guideline with a RADT for scores ≥ 3 (GL-RADT-group) or usual care (UC-group). All practices were visited and instructed by the study team (outreach visits) and supplied with material according to their group. The practices were asked to recruit 11 consecutive patients ≥ 2 years with an acute sore throat and being at least moderately impaired. A study throat swab for GAS was taken in every patient. The antibiotic prescription rate at the first consultation was the primary outcome. RESULTS: From October 2010 to March 2012, 68 general practitioners in 61 practices recruited 520 patients, 516 could be analyzed for the primary endpoint. Antibiotic prescription rates did not differ between groups (p = 0.162) and were about three times higher than the GAS rate: GL-group 97/187 patients (52%; GAS = 16%), GL-RADT-group 74/172 (43%; GAS = 16%) and UC-group 68/157 (43%; GAS = 14%). In the GL-RADT-group 55% of patients had scores ≥ 3 compared to 35% in GL-group (p < 0.001). After adjustment, in the GL-RADT-group the OR was 0.23 for getting an antibiotic compared to the GL-group (p = 0.010), even though 35 of 90 patients with a negative Strep-test got an antibiotic in the GL-RADT-group. The prescription rates per practice covered the full range from 0 to 100% in all groups. CONCLUSION: The scores proposed in the implemented guideline seem inappropriate to lower antibiotic prescriptions for sore throat, but better adherence of practitioners to negative RADTs should lead to fewer prescriptions. TRIAL REGISTRATION: DRKS00013018, retrospectively registered 28.11.2017.

BACKGROUND: The homeless are often in poor health, and their risk of premature death is three to four times that of the general population. This article is intended to provide an overview of the medical care of the homeless in Germany. METHODS: We selectively reviewed pertinent scientific and non-scientific publications from the years 2000-2017 that were retrieved from PubMed, from the reports of the German Homeless Aid Society (Bundesarbeitsgemeinschaft Wohnungslosenhilfe), from the websites of homeless aid organizations, and from Google Scholar. RESULTS: At least 75% of the homeless currently suffer from a mental illness requiring treatment. Common somatic problems include respiratory (6-14%) and cardiovascular disorders (7-20%), injuries and intoxications (5-15%), and infectious and parasitic diseases (10-16%). To circumvent the multiple barriers impeding homeless people's access to standard medical care (lack of health insurance, a feeling of being unwelcome, lack of disease awareness, impaired capacity for compliance), medical help is offered to them outside the system in a number of ways, embedded in an overall scheme of social and practical assistance with daily living. These medical resources differ from region to region. They are often underfinanced and tend to focus on acute general medical care, with limited access to specialists. CONCLUSION: More heath care resources need to be made available to the homeless beyond standard medical care. Concrete suggestions are discussed in the text.
