Methods: This was a retrospective cohort study of all patients (VFRs and non-VFRs) who received pre-travel healthcare at the TTMC from 2012-2013. Data on demographic information, duration and destination of travel, immunizations and preventive medication prescriptions was obtained from medical records. Demographics and rates of completing recommended immunizations were compared using chi-square tests.
Results: There were 393 VFRs and 1680 non-VFRs seen in the TTMC during the study period. VFRs were younger and more likely to use interpreters (19.1%) and have Medicare (27.7%) insurance. There were more VFRs traveling to Africa (47% VFR vs 30% non-VFR, p<0.0001), Asia (39% vs 30%, p=0.0005), and the Middle East (11% vs 6%, p=0.0014). VFRs had longer durations of travel: 51% for >4 weeks compared to 21% for non-VFRs (p<0.0001). VFRs had lower rates (P<0.05) of completion of tetanus (81% VFR vs 91% non-VFR), polio (86.1% vs 93%), rabies (12% vs 27%), and zoster vaccinations (54% vs 71%). VFRs had higher rates of completion of MMR vaccinations (87% vs 68%, p=0.01). There were no significant differences between VFRs and non-VFRs for other recommended vaccinations or antimalarial and antidiarrheal prescriptions.
Conclusion: VFRs who accessed pre-travel healthcare were found to have longer travel durations and lower rates of vaccine completion than non-VFRs. More research is needed to understand the reasons for this disparity, to inform appropriate changes in pre-travel counselling for VFRs, and the effects of these reduced vaccination rates on infections rates.
