It is often argued that irrational prescribing is higher during out-of-hours (OOH) consultations.Aim To obtain insight into the quantity and quality of OOH antibiotic prescribing for commonly presented infectious diseases.Design and setting Two two-way comparisons of 1) nationally dispensed antibiotics during office hours and OOH care, using data from the Dutch Foundation of Pharmaceutical Statistics, and 2) regional prescribing quality data from 45 primary care practices from Utrecht and its vicinity, and two large OOH services in Utrecht and Woerden.Method From the national data, yearly dispensed antibiotics were analysed per prescriber type, with respect to time (office hours or OOH) of prescription, types of antibiotics, and patients’ age group. Regional prescribing rates, choice of antibiotic, and appropriateness of prescribing were compared for otitis media, sinusitis, tonsillitis, bronchitis, cystitis, and impetigo. Appropriateness was assessed by comparing all relevant information from medical files with the guideline recommendations.Results Only 6% of GP-prescribed antibiotics were prescribed OOH. OOH, cystitis and acute otitis media presented most often. First-choice prescribing was comparable for the two settings, whereas prescribing rates were higher OOH, with comparatively more amoxicillin(/clavulanate). The appropriateness evaluation, however, revealed that overprescribing was comparable, or even lower than, for daily practice.Conclusion The suggestion that OOH antibiotic prescribing quality is worse than in daily practice does not seem founded. The higher OOH prescribing rates can be explained by a different population of presenting patients. The appropriateness of prescribing rather than prescribing rates, therefore, should be used to determine quality. ER -
