Development of a quick guide for assessment of the most frequently used renal risk medication in Danish hospitals and primary care

Due to changes in pharmacokinetics and pharmacodynamics, patients with impaired renal function suffer an increased risk of suboptimal and potentially harmful medication treatment. This necessitates careful consideration of medications affected by impaired renal function when performing medication reviews. The aim of this study was to develop a quick guide (a list of recommendations) for assessing renal risk medications in medication reviews led by hospital pharmacists. The list was based on the 100 most frequently used medications in Danish hospitals and primary care. After combining the 200 records, 29 duplicates were excluded resulting in a pool of 171 medications. Assessment by two clinical pharmacists led to the exclusion of 121 medications. Of the remaining 50 medications, seven were discussed among the two pharmacists, and two of these were also in the research group to reach a consensus. The renal risk quick guide comprised 50 medications. The most prevalent medications on the list were from Anatomical Therapeutic Chemical Classification System (ATC)-group N, C and L. Recommendations from two databases were included in the quick guide in order to provide clinical pharmacists with existing, updated evidence on medication use in impaired renal function. The next step is to test the feasibility of the quick guide in daily practice when performing medication reviews.
