Background: The Deployment and Travel Medicine Knowledge, Attitudes, Practices, and Outcomes Study (KAPOS) evaluates health outcomes and provider practices associated with travel and deployments within the US Military Health System. We analyzed prescribing errors for chloroquine malaria chemoprophylaxis between travel medicine specialists and non-specialists over a five-year period.
Methods: A sample of 291 chloroquine prescriptions were reviewed to determine if malaria chemoprophylaxis was appropriate for destination of travel based on both transmission and chloroquine resistance risk. We included non-active-duty beneficiaries of all ages seeking care at military treatment facilities.
Results: 10.3% (n = 30) of patients were prescribed chloroquine inappropriately. Non-travel medicine specialists prescribed chloroquine inappropriately more frequently than travel medicine specialists with 16.5% vs 2.3% error, respectively. Physicians were less likely to erroneously prescribe chloroquine as compared to non-physicians with 6.4% vs 22.2% error, respectively. 93.3% of prescribing errors were due to chloroquine-resistance presence at the travel destination. Africa was the most common destination of erroneous prescriptions, creating significant risk for travelers.
Conclusions: While chloroquine is infrequently prescribed, this analysis demonstrates travel medicine proficiency is associated with reduced errors, highlighting the need to supply travel medicine education and decision support tools to non-specialists, to safeguard patients who seek pre-travel medical care.
