STUDY DESIGN: A descriptive content analysis of patient organisation websites was conducted.
METHODS: The Google® search engine was interrogated using search terms related to the principal chronic diseases from the Global Burden of Disease Study. Data relating to 41 travel health variables were extracted from each eligible website. An aggregate quality score was derived for each organisation based on the presence of specific website information. Visitor usage and search analytics for each organisation's website were also described.
RESULTS: We examined 145 official organisation websites relating to 10 major chronic illnesses. The largest number of websites was retrieved for patients with cancer (n = 36). Only 21 (16.5%) websites provided information on fitness-to-travel considerations. COPD websites had the highest average quality score (17.68%), followed by diabetes (14.91%) and dementia (13.28%). Mental health illness websites had the lowest score of 1.33%. There was a trend towards increased emphasis on pre-travel preparation and medications. Insect bite avoidance, malaria, animal bites, jet lag, and repatriation were addressed to the least extent.
CONCLUSIONS: Our analysis exposes significant deficits in the coverage of travel health topics. Patient organisations should provide accessible pre-travel health advice to website users. Future research should elucidate the influence of web-based pre-travel health information on the behaviour of travellers with chronic disease.
