Prescription patterns in the treatment of acutely ill seafarers over a three-year observation period

The provision of healthcare for seafarers is challenging due to their isolated working conditions and limited access to healthcare. Telemedical maritime assistance relies on pre-stocked medical chests aboard vessels. However, the contents of these medical chests are not globally standardized, and current data on prescription patterns is limited.

A retrospective observational cohort study was conducted, analyzing medical records from ships that received telemedical assistance between 2021 and 2023. Data were obtained from medical reports submitted by onboard medical officers and an internal medical record registry.

In total, 9,458 individual patients received medical assistance, and 11,698 medications were prescribed. The mean patient age was 38.7 years (range 0-91 years), and patients aged 30-49 years were the most likely to receive medication. Merchant ships were the most common type of vessel requiring medical assistance, and they also had the highest probability for drug prescriptions. Approximately 80% of patients were prescribed medications, and patients required on average 1.24 prescriptions (range 0-6). A total of 266 individual types of medication were available for prescription. Overall, patient demographics and prescription patterns did not change over the three-year period.

The prescription patterns in the treatment of acutely ill seafarers are highly variable due to excessive availability of different drugs. The rare use of certain medications suggests potential inefficiencies in the stock management of medical chests, warranting further evaluation. These findings underscore theneed for standardizing medical chests based on a data-driven approach. Medication use in telemedical care of seafarers is frequent but highly variable. A data-driven standardization of medical chests may improve efficiency and ensure availability of essential drugs.
