Wie vollständig ist der Bundeseinheitliche Medikationsplan? Eine Analyse bei Krankenhausaufnahme

Background At inpatient admission, the timeliness and completeness of the Germany-wide standardised medication list (“Bundeseinheitlicher Medikationsplan”) often seems inappropriate. It is also unclear which characteristics of the lists increase the probability of discrepancies. Methods A total of 100 medication lists of elective patients of a surgical clinic were retrospectively evaluated with regard to potential discrepancies compared to the standardised medication reconciliation. The discprepancies were assigned to 7 categories: drug taken is missing on the list, drug on the list is no longer taken, strength or dosage is missing at the list or is incorrect, or the documented dosage form is different. Advice on patient safety, involved drugs and dosage forms were also recorded. Multivariate analyses were used to investigate the influence of the timeliness, number of drugs and issuing medical specialty of the lists on the type and number of discrepancies. Results Compared to the medication reconciliation, 78 % (78/100) of the lists showed discrepancies. A total of 226 deviations (2.3 ± 0.6 deviations/list) were documented. Most often, a drug was missing from the list (n = 103). Of all recommendations, 64 % (83/177) concerned the perioperative management of anticoagulants (n = 55) and antidiabetics (n = 28), corresponding to 62 % (62/100) of the lists. In the multivariate analysis, only the risk of incorrect information on strength and dosage increased significantly with the age of the lists (p = 0.047) and was more than twice as high when the list was more than one month old. Conclusions The timeliness, completeness and aspects of patient safety must be comprehensively validated. Medication lists that are older than 1 month should be checked particularly critically with regard to information on strength and dosage and the plan should be updated accordingly at regular intervals.
