Abstract
BACKGROUND: The epidemiology of patient safety problems (PSPs) in the German ambulatory care sector is largely unknown. So far, there has been a lack of appropriate survey instruments. OBJECTIVE: Development and application of a questionnaire (PSP-AMB), which records the epidemiology of PSP in the ambulatory care sector from the patient's perspective by using computer-assisted telephone interviews (CATI) on a population sample of ≥40-year-olds. METHODS: The questionnaire items were developed by means of a literature search and guided interviews with ambulatory care physicians (N=10) and patients (N=20). The conversion to CATI and its application in the field was carried out by a survey institute. Qualitative (N=20) and quantitative (N=110) pretests were conducted before going into the field. The sample was generated via randomly generated fixed and mobile telephone numbers. RESULTS: PSP-AMB collects 32 PSPs in seven areas of medical treatment, from medical history-taking to practice organisation, and surveys all PSPs from the last 12 months (PSP-one-year incidence), PSPs with harm since the age of 40 (PSP-40+-prevalence), as well as PSPs resulting in death or severe need for care via proxy survey of the participants' parents and children. Detailed questions record the consequences and handling of PSPs and participants' socio-demographic data. Between May and October 2018, a total of 10,037 citizens (participation rate: 12.4%) were interviewed. The drop-out rate was 8.3%. The sample represents the German population aged 40 years or older. DISCUSSION: PSP-AMB is suitable for systematically recording PSPs in the ambulatory care sector from the patient's perspective. Thus, PSP-AMB meets the international demand to actively involve patients as a valuable source of information to improve patient safety.
