Abstract

Objective To assess if data collected by a consumer organisation are valid for a health service research study on physicians' performance in preventive care. To report first results of the analysis of physicians performance like consultation time and guideline adherence in history taking.

Design Secondary data analysis of a clustered cross-sectional direct observation survey.

Setting General practitioners (GPs) in Vienna, Austria, visited unannounced by mystery shoppers (incognito standardised patients (ISPs)).

Participants 21 randomly selected GPs were visited by two different ISPs each. 40 observation protocols were realised.

Main outcome measures Robustness of sampling and data collection by the consumer organisation. GPs consultation and waiting times, guideline adherence in history taking.

Results The double stratified random sampling method was robust and representative for the private and contracted GPs mix of Vienna. The clinical scenarios presented by the ISPs were valid and believable, and no GP realised the ISPs were not genuine patients. The average consultation time was 46 min (95% CI 37 to 54 min). Waiting times differed more than consultation times between private and contracted GPs. No differences between private and contracted GPs in terms of adherence to the evidence-based guidelines regarding history taking including questions regarding alcohol use were found. According to the analysis, 20% of the GPs took a perfect history (95% CI 9% to 39%).

Conclusions The analysis of secondary data collected by a consumer organisation was a valid method for drawing conclusions about GPs preventive practice. Initial results, like consultation times longer than anticipated, and the moderate quality of history taking encourage continuing the analysis on available clinical data.

  • Data sharing statement The data of this study are owned by the Austrian Consumer Organisation (Verein für Konsumenteninformation, VKI). On our written request in October 2008, VKI provided us with the electronic data set (raw data: Excel file, 23 lines), and hardcopies of the completed medical result sheets (34 sheets) for the sole purpose of conducting health service research studies by us, the International Screening Committee for Austria. We extracted data from the hardcopies and added it to our own secondary data set. We encourage any researcher to ask permission and perhaps request the data set also from VKI in Vienna, Austria (http:\\www.vki.at).
