Patient safety incidents involving transdermal opioids: data from the Danish Patient Safety Database

Background Transdermal opioids are widely used among elderly adults with chronic pain. However, transdermal patches may be involved in a significant proportion of opioid-related patient safety incidents, as the application process includes several subprocesses, each associated with an individual risk of error. Objective The aim was to obtain specific knowledge on patient safety incidents related to transdermal opioid treatment within both the primary care sector and the hospital sector in Denmark. Setting The study is descriptive with data provided by the Danish Patient Safety Database. Methods We manually retrieved all patient safety incidents concerning transdermal opioids reported for 2018 from (1) the hospital sector and (2) the primary care sector. Study data were collected and managed using REDCap electronic data capture tools. Main outcome measure The available information for each incident was sorted into the following categories: location, medication process, type of problem, outcome at time of reporting, and outcome classification. Results A total of 866 patient safety incidents involving transdermal opioids were reported to the Danish Patient Safety Database in 2018. No fatal incidents were present in the database. In 386 cases, the incidents were reported as harmful, and these 386 cases were analysed. Most reports came from the primary care sector (nursing home, home care or social housing). The majority of incidents were related to the administration of the patch in the medication process, and the most prevalent problem was the omission of doses. Conclusion This study has demonstrated that the administration of transdermal opioids is challenging and may cause harm, particularly in the primary care sector. To improve patient safety, optimized systems, including guidelines on drug management and the continuing education of healthcare personnel in transdermal opioid management, are necessary. These guidelines should preferably incorporate reminders and checklists, since the omission of doses was the most reported problem.
