Flight safety risk assessment of self-medication among fighter pilots: a cross-sectional study.

BACKGROUND: Fighter pilots are a specific population in which any adverse drug reaction can unpredictably interact with aeronautical constraints and thus compromise flight safety. This issue has not been evaluated in risk assessments. AIM: To provide a semi-quantitative assessment of the risk to flight safety of self-medication in fighter pilots. METHOD: A cross-sectional survey that aimed at identifying the determinants of self-medication in fighter pilots was conducted. All medications consumed within 8 h preceding a flight were listed. A modified Failure Mode and Effects Analysis was performed, and any adverse drug reaction reported in the French marketing authorization document of a drug was considered a failure mode. The frequency of occurrence and severity were evaluated using specific scales to assign each to three risk criticality categories: acceptable, tolerable, and unacceptable. RESULTS: Between March and November 2020, the responses of 170 fighter pilots were analyzed, for an overall return rate of approximately 34%. Among them, 78 reported 140 self-medication events within 8 h preceding a flight. Thirty-nine drug trade names (48 different international nonproprietary names) were listed, from which 694 potential adverse drug reactions were identified. The risk criticality was considered unacceptable, tolerable and acceptable for 37, 325 and 332 adverse drug reactions, respectively. Thus, the risk criticality was considered unacceptable, tolerable and acceptable for 17, 17, and 5 drugs, respectively. CONCLUSION: This analysis suggests that the overall risk to flight safety of the current practice of self-medication in fighter pilots may be considered at least tolerable, or even unacceptable.

Self-Medication Among Military Fighter Aircrews.

BACKGROUND: The practice of self-medication among military fighter aircrew could compromise flight safety because of the adverse effects that can occur in flight. However, data on this subject is scarce. The aim of this study was to identify the determinants of the practice in this population.METHODS: A cross-sectional study was carried out among the French Air Force fighter aircrew based on an anonymous questionnaire distributed electronically. The questions included personal characteristics, opinions, and relations with the healthcare domain as well as the use of self-medication in general and before a flight.RESULTS: Between March and November 2020, 170 questionnaires were reviewed for an overall return rate of approximately 34%. Our data showed an absolute self-medication rate of 97.6%, but the frequency of its use was rare or nonexistent in 53.5% of cases. Factors associated with a more frequent use of self-medication were the function of pilot, age under 35, having a regular prescription, lacking intentionality toward getting enough sleep, having confidence in the medical profession, and some specific clinical situations. The consumption of 97 medications was recorded and 49 before a flight.DISCUSSION: Despite the limitations due to the design of this survey, results suggest that the use of self-medication in fighter aircrews is a reality, but that the frequency of its use is less common. This practice is probably the result of a complex interaction between many personal factors. However, its impact on flight safety remains uncertain.du Baret de Limé M, Monin J, Leschiera J, Duquet J, Manen O, Chiniard T. Self-medication among military fighter aircrews.
