Brief title
Health condition
Older travelers, illness during travel and 4 weeks after return, co-morbidity, polypharmacy, hand grip strength and cognitive functioning before travel (Dutch: oudere reizigers, ziekten tijdens een reis en 4 weken na terugkomst, co-morbiditeit, polyfarmacie, handknijpkracht en cognitief denkvermogen voor vertrek)

Outcome measures
Primary outcome
The main endpoints of the primary objective are the occurrence, duration in days and morbidity of an acquired illness during travel and four weeks after return. The focus will be on different type of health complaints:
- Fever
- Gastrointestinal
- Respiratory
- Dermatological
- Cardiovascular
- Genitourinary tract
Other endpoints of the objective are:
- Hand grip strength in kilograms before travel (vitality).
- Patient-reported health before, during and after travel (SF-36 and Charlson Comorbidity Index).
- Independence in activities of daily living (Katz-ADL).
- Cognitive functioning before travel (6CIT).
Secondary outcome
- Frequency of medical conditions before travel.
- Frequency of medication use before travel.
- Number of medicines used before travel (e.g. polypharmacy).
- Frequency of infectious or non-infectious illnesses during travel or in the Netherlands until four weeks after return.
- Frequency of a new medical condition or an exacerbation of underlying medical condition during travel or in the Netherlands until four weeks after return.
- Percentage of medication adjustments during travel and four weeks or in the Netherlands until four weeks after return.
- Frequency of self-reported compliance with prescribed antimalarials during travel.
- Frequency of doctor visits abroad or in the Netherlands until four weeks after return.
- Frequency and duration of hospitalizations abroad or in the Netherlands until four weeks after return.

Background summary
People live longer in better health and are fit to travel at increasing ages. Various new risks can be faced during international travel due to age related health problems. Also comorbidities and accompanying polypharmacy can cause severe health problems, especially in elderly travelers. We therefore hypothesize that travelers of 60 years and older consulting pre-travel clinics and GP’s are not getting the tailored advice appropriate for their needs.
Study objective
To determine frequency, duration and morbidity of (travel-related) health problems and/or exacerbations of underlying illnesses among Dutch travelers of 60 years and older visiting (sub)tropical destinations for a short-term stay to establish risk profiles characterized by vitality, health status and cognitive functioning.
Study design
- Before travel (grip strength, cognitive functioning, questionnaire 1, start diary)
- During travel (diary)
- After travel (after 1 week questionnaire 2, filling in diary until 2 weeks after return)
- After travel (4 weeks after return questionnaire 3, some travelers 8 weeks after return questionnaire 4)
Intervention
No intervention (prospective observational cohort study)
