A stratified random sample of 376 German community pharmacies formed the basis of this nationwide investigation. The authors used the simulated-patient or mystery-caller methodology, considered the gold standard for evaluating real-world counseling behavior; eight trained female callers, aged 21–24, enacted a single standardized vignette. In that script, a combined oral contraceptive pill had been missed once after sexual intercourse but could still be taken within a 12-hour window—circumstances under which the BAK guideline indicates that oral EC is not required. To improve internal validity, each call was observed by a second study team member. The study team excluded some calls from primary analysis; 322 calls remained for the principal outcome assessment.
The German Federal Chamber of Pharmacists provides a guideline checklist intended to structure counseling. Investigators scored information gathering against four checklist items. The median questioning score across included calls was 2.0 out of 4.0, indicating partial use of the checklist on average. The source did not supply verbatim checklist question wording in the article text, nor did it make checklist use mandatory in practice; the study used the checklist as an audit tool rather than as a directive applied by pharmacy staff.
Study results showed that an appropriate outcome—meaning pharmacy staff did not recommend oral EC for the presented scenario—occurred in 44.4% (143/322) of calls. By contrast, oral EC was unnecessarily recommended in 49.1% (158/322) of calls. Those figures reflect counseling outcomes in telephone consultations after the over-the-counter switch in Germany; the article noted increased OTC dispensing since 2015 but did not link individual sales data to specific counseling instances in this dataset. The authors framed unnecessary recommendations as clinically and economically relevant because they expose women to avoidable hormonal medication and may impose a financial burden, given that the cost of oral EC is relatively high compared with many other OTC medicines.
A multivariable logistic regression model examined associations with achieving an appropriate outcome. The model identified two variables with significant associations: a higher score on the information-gathering checklist and the identity of the mystery caller. The source reported these associations without speculating beyond the observed relationships. The article did not provide additional specific pharmacy-level variables (for example, staff qualification mix or exact telephone workflow) as independent predictors in the published regression table text available in the main body.
In addition to quantitative outcomes, the study team documented qualitative findings. The authors reported examples of positive counseling behaviors—instances where staff asked relevant questions and advised against EC when indicated—and contrasted them with notable deficiencies, such as incomplete questioning or premature recommendation of oral EC. The source emphasized variability in practice and suggested that inconsistent use of the BAK checklist likely contributed to inappropriate recommendations during telephone consultations.
The authors acknowledged limitations intrinsic to the mystery-caller method and to the dataset: some calls were excluded from analysis (322/376 remained), and the source did not report certain operational details such as the exact checklist question text within the published article body, the training content of pharmacy staff, or granular demographic features of counseling personnel. The study team recommended that the BAK guideline explicitly endorse consistent use of the checklist for telephone consultations and suggested targeted training efforts for pharmacy staff to address professional and communication deficits. They also noted an unexpected finding—the identity of specific mystery callers correlated with better outcomes—and called for further research on whether vocal characteristics or surnames influence telephone-based counseling decisions. The article ends with these practical next steps and unanswered questions, rather than a broad concluding statement.
