Background Systematic reviews that synthesize safety outcomes pose challenges (e.g. rare events), which raise questions for grading the strength of the body of evidence. This is maybe one reason why in many potentially inappropriate medication (PIM) lists the recommendations are not based on formalized systems for assessing the quality of the body...

Background Person-centred care (PCC) has been suggested as the preferred model of dementia care in all settings. The EPCentCare study showed that an adapted PCC approach was difficult to implement and had no effect on prescription of antipsychotics in nursing home residents in Germany. This paper reports the qualitative process evaluation to identi...
Article
Background Quality indicators to assess the quality of primary care have only been applied on a national or regional level in European countries, and there have been no comparisons between regions of different countries. In the interventional pre-post-study “Improvement of Quality by Benchmarking – IQuaB” (level of evidence: 3), we aimed to improve...

Objective Due to the increasing concerns about polypharmacy, there is a growing need for clinical recommendations for drug discontinuation. This requires studies investigating the process on several levels. This paper addresses the methodological problems of drug discontinuation trials (DDTs). To that end, we offer a new typology of research aims a...

Background Currently 21% of the German population is older than 65 years. Above this age, the risk of suffering from chronic disease and mental disorders increases rapidly. Therefore, physical inactivity is one of the most important public health concerns among older people. To address this issue, we have conceptualised and evaluated a simple and l...

Background The treatment of upper respiratory tract infections (URTIs) accounts for the majority of antibiotic prescriptions in primary care, although an antibiotic therapy is rarely indicated. Non-clinical factors, such as time pressure and the perceived patient expectations are considered to be reasons for prescribing antibiotics in cases where t...

Background: Proton pump inhibitors (PPIs) are increasingly being prescribed, although long-term use is associated with multiple side effects. Therefore, an electronic decision support tool with the aim of reducing the long-term use of PPIs in a shared decision-making process between general practitioners (GPs) and their patients has been developed...
