358 CHAPTER 4.3 patients experiencing their first potentially preventable DRA were analysed (Figure 2). In 22 of these 77 MEs (28.7%), a DRA adjudication member was consulted by the primary researchers for further specification of the ME to finalise the assessment of ME detectability at the time of the in-hospital medication review. The median age of participants was 80 years (interquartile range [IQR] 76–86) at the time of the in-hospital medication review. Participants had a median of 14 (IQR 9–19) co-morbidities and were prescribed a median of 10 (IQR 8–14) medications. Participants had a median eGFR of 51 ml/min/1.73m2 (IQR 36–66). Other baseline characteristics of the study population at the time of the in-hospital medication review are illustrated in Table 1. Figure 2. Flowchart of the study population. DRAs were considered potentially preventable if medication errors were the main or contributory cause of the readmission. Non-preventable DRAs were caused by nonpreventable adverse drug reactions. DRA = Drug related admission
