Assessing the quality of medication documentation: development and feasibility of the MediDocQ instrument for retrospective chart review in the hospital setting

OBJECTIVE: The medication process requires clear and transparent documentation in patient records. Incomplete or incorrect medication documentation may contribute to inappropriate clinical decision-making and adverse events. To comprehensively assess the quality of in-hospital medication documentation, we developed a retrospective chart review (RCR) instrument. We report on the development process, the feasibility of the instrument and describe our application of the instrument to a sample of patient records. DESIGN: Cross-sectional study using an RCR instrument to evaluate paper-based, non-standardised prescription and medication administration charts (MediDocQ). SETTING: Two German university hospitals. PARTICIPANTS: Records from 1361 patients admitted between April and July 2015 were evaluated. METHODS: The MediDocQ development process comprised six consecutive stages: focused literature review, web-based search, initial patient record screening, review by project advisory board, focus groups with professionals and pilot testing. The final 54-item RCR instrument covers three key components of medication documentation: (1) completeness of documented information (including prescription, medication administration and pro re nata (PRN) medication), (2) quality of transcriptions and (3) compliance with chart structure, legibility, handling of deletions and chart corrections. Descriptive statistics are presented as mean values, SD, median and interquartile ranges for individual items. RESULTS: Overall, 33 out of 54 items resulted in mean values above 0.75, indicating high-quality medication documentation. Documentation quality was particularly compromised for verbal and PRN orders (which involve more steps than standard orders) and when documentation was not completed at the same time as medication administration. CONCLUSIONS: MediDocQ is a patient safety instrument that can be used to evaluate the quality of medication documentation and identify components of the process where intervention is required. In our setting, standardisation of medication documentation, particularly regarding medication administration and PRN medication is a priority.
