The programme of the German Congress for Laboratory Medicine 2022 was essentially designed by the divisions of the German Society for Clinical Chemistry and Laboratory Medicine (DGKL). Almost all chairpersons of the divisions organised a 90-min symposium on current topics, i.e. conceptualised the symposia and invited speakers. For this article all chairpersons summarised the lectures that were given within the symposia. The DGKL's work is structured into 5 areas of expertise: Molecular Diagnostics, Learning & Teaching, Quality & Management, Laboratory & Diagnostics and Biobanks & Informatics. The areas of expertise are in turn subdivided into divisions. About the history of the establishment of this new structure within the DGKL you can find information in the editorial of this issue.

Background: Elderly patients are particularly vulnerable to adverse drug reactions, especially if they are affected by additional risk factors such as multimorbidity, polypharmacy, impaired renal function and intake of drugs with high risk potential. Apart from these clinical parameters, drug safety and efficacy can be influenced by pharmacogenetic factors. Evidence-based recommendations concerning drug-gene-combinations have been issued by international consortia and in drug labels. However, clinical benefit of providing information on individual patient factors in a comprehensive risk assessment aiming to reduce the occurrence and severity of adverse drug reactions is not evident. Purpose of this randomized controlled trial is to compare the effect of a concise individual risk information leaflet with standard information on risk factors for side effects. Methods/Design: The trial was designed as a prospective, two-arm, randomized, controlled, multicenter, pragmatic study. 960 elderly, multimorbid outpatients in general medicine are included if they take at least one high risk and one other long-term drug (polymedication). As high risk "index drugs" oral anticoagulants and antiplatelets were chosen because of their specific, objectively assessable side effects. Following randomization, test group patients receive an individualized risk assessment leaflet evaluating their personal data concerning bleeding- and thromboembolic-risk-scores, potential drug-drug-interactions, age, renal function and pharmacogenetic factors. Control group patients obtain a standardized leaflet only containing general information on these criteria. Follow-up period is 9 months for each patient. Primary endpoint is the occurrence of a thromboembolic/bleeding event or death. Secondary endpoints are other adverse drug reactions, hospital admissions, specialist referrals and medication changes due to adverse drug reactions, the patients' adherence to medication regimen as well as health related quality of life, mortality and resulting costs. Discussion: Despite extensive evidence of risk factors for adverse drug reactions, there are few prospective trial data about an individualized risk assessment including pharmacogenetic information to increase patient safety. By conducting a health economic analysis, we will evaluate if the application of an individualized drug therapy in daily routine is cost-effective. [ABSTRACT FROM AUTHOR]
