The Knowledge, Attitudes, and Practices of Primary Healthcare Physicians in the Al Qassim Region, Saudi Arabia Regarding Travel Medicine: A Cross-Sectional Study

Background and objective In the age of globalization, diseases associated with travel have emerged as a focal point of public health interest. This has become particularly relevant in Saudi Arabia after the changes in tourism policy in recent years. Primary care physicians are expected to suspect diseases of importance in certain geographic areas. They should dispense pre- and post-travel advice. This study aimed to assess the knowledge, attitudes, and practices of primary care physicians in the Al Qassim region, Saudi Arabia regarding travel medicine. Methods This cross-sectional study was conducted in the Al Qassim region, Saudi Arabia between October and November 2023. We reached out to all primary care physicians in the region regardless of their gender, nationality, and years of experience. The data were collected using a self-administered questionnaire, which was designed based on the available literature and validated by experts. Results A total of 197 physicians participated in the study; 74% were male, 46% were general practitioners, and 48% had 5-10 years of experience. More than half (51%) of the participants reported a weekly patient load of 50-100, while 47% engaged with 5-10 travelers annually; 53% provided travel health advice and a quarter of primary healthcare physicians never attended travel update sessions or conferences. In the last six months, 48% and 43% of the physicians conducted pre- and post-travel consultations respectively. Approximately 49.2% demonstrated a fair knowledge of the topic. Factors associated with fair knowledge included non-Saudi nationality, age below 30 years, minimal traveler exposure, and infrequent conference attendance (p<0.05). A positive attitude was linked to being under 30 years old, having <5 years of experience, seeing <5 travelers yearly, and possessing a fair knowledge of the topic (p<0.05). Conclusions Overall, about half of the physicians in the Al Qassim region engage with travelers and demonstrate good attitudes and practices toward travel medicine. Opening Saudi borders to tourism necessitates the inclusion of travel medicine in continuing medical education programs to prepare primary care physicians to care for travelers more efficiently.

The Traveller's Risk Perception (TRiP) questionnaire: pre-travel assessment and post-travel changes

BACKGROUND

Travellers' risk perception is a key component of travel risk assessment because it influences the adequate implementation of safety precautions. The aims of this study are to validate a tool to analyse travellers' risk perception to identify which factors can influence it and how it changes upon return.

METHODS

The Traveller's Risk Perception (TRiP) questionnaire was developed and administered to outpatients before and after travel in three travel clinics. A principal component analysis (PCA) was performed to validate the questionnaire and multivariate regression analysis was used to evaluate the effect of travellers' characteristics on the risk scores.

RESULTS

A total of 1020 travellers completed the questionnaire. PCA identified two latent factors: 'generic-disseminated risks' and 'specific-circumstantial risks'. Cronbach's α was acceptable (0.76 and 0.70, respectively). The 'generic-disseminated risks' dimension scored higher than the 'specific-circumstantial risks' (p<0.001). The items with the highest scores were insect bites, gastrointestinal disorders and malaria. The mean scores were significantly lower after the travel for all items but one.

CONCLUSIONS

The TRiP questionnaire is a valid and reliable tool for rating travellers' perceptions. Staff in travel clinics should be trained to systematically assess travellers' risk perception in order to tailor the consultation according to specific information needs.

Pre-travel counseling for immunocompromised travelers: A 12-year single-center retrospective review

BACKGROUND

Immunocompromised travelers (ICTs) are medically complex and challenging for travel medicine providers. Our study hypothesizes that ICTs have high-risk travel itineraries and do not have adequate immunity against vaccine-preventable infections.

METHODS

This retrospective review of 321 ICTs from 2004 to 2015 included patients with solid organ transplant (SOT, n = 134), connective tissue disease (CTD, n = 121), inflammatory bowel disease (IBD, n = 46), and human immunodeficiency virus (HIV, n = 20). Variables included immunosuppressive medications, hepatitis A and B vaccination and serology, gamma-globulin use, and antimalarial and antidiarrheal prophylaxis. Chi-square analysis was used for categorical variables and Kruskal-Wallis for continuous variables.

RESULTS

Malaria-endemic regions accounted for 38.9% (125/321) of travel destinations. High-risk activities were planned by 37.4% (120/321) of travelers. A significant proportion of HIV patients [70.0% (14/20)] visited friends and relatives, whereas other ICTs traveled for tourism. Hepatitis A and B vaccination rates were 77.3% (248/321) and 72.3% (232/321). Post-vaccination hepatitis A and B serologic testing were completed by 66.1% (41/62) and 61.1% (11/18) of travelers, respectively.

CONCLUSION

ICTs demonstrate differences in travel patterns and risk. Serologic testing was uncommon, and vaccination rates were low. Providers should screen ICTs early for upcoming travel plans and advise vaccine completion prior to departure.

Does the DOSPERT scale predict risk-taking behaviour during travel? A study using smartphones

BACKGROUND

Despite the continuing growth of international tourism, very little research has been done on the link between individual risk attitudes and health behaviours during travel. Our study uses a validated risk-taking questionnaire Domain-Specific Risk-Taking Scale (DOSPERT) and data from a smartphone application to study the association between pre-travel risk attitudes and the occurrence of behaviours during travel.

METHODS

A prospective cohort of travellers to Thailand used a smartphone application to answer a daily questionnaire about health behaviours and events. Prior to travel, participants completed the DOSPERT, a validated 30-item scale that assesses risk-taking and perception in five content domains: financial decisions, health/safety, recreational, ethical and social decisions. Multiple linear regression models were used to model the relationship between DOSPERT risk-taking subdomain score and health behaviour.

RESULTS

Of the 75 travellers that completed the study, 70 (93.3%) completed the DOSPERT pre-travel. Men, backpackers and young travellers reported a higher willingness to take recreational risks than women, luxury travellers and older travellers. Incidence of drug and alcohol risk behaviours during travel, itching from mosquitoes, smoking and failing to use a seatbelt in automobiles while at home were all significantly associated with an individual's score on the health and safety DOSPERT subdomain.

CONCLUSIONS

In our study, individual scores on risk-taking in the health and safety subdomain of the DOSPERT questionnaire seem to be predictive of health behaviours both during travel and at home. By pairing new methods of data collection with questionnaires such as DOSPERT that identify key traveller characteristics to intervene on, travel medicine doctors will be able to provide more specialised health advice, ensuring that all travellers receive well-rounded advice about the full range of health challenges they will face during travel.

The quantified self during travel: mapping health in a prospective cohort of travellers

BACKGROUND

Travel medicine research has remained relatively unchanged in the face of rapid expansion of international travel and is unlikely to meet health challenges beyond infectious diseases. Our aim was to identify the range of health outcomes during travel using real-time monitoring and daily reporting of health behaviours and outcomes and identify traveller subgroups who may benefit from more targeted advice before and during travel.

METHODS

We recruited a prospective cohort of travellers ≥ 18 years and planning travel to Thailand for <5 weeks from the travel clinics in Zurich and Basel (Switzerland). Participants answered demographic, clinical and risk behaviour questionnaires pre-travel and a daily health questionnaire each day during travel using a smartphone application. Environmental and location data were collected passively by GPS. Classification trees were used to identify predictors of health behaviour and outcomes during travel.

RESULTS

Non-infectious disease events were relatively common, with 22.7% (17 out of 75 travellers) experiencing an accident, 40.0% ( n  = 30) a wound or cut and 14.7% ( n  = 11) a bite or lick from an animal. Mental health associated events were widely reported, with 80.0% ( n  = 60) reporting lethargy, 34.7% ( n  = 26) anxiety and 34.7% ( n  = 26) feeling tense or irritable. Classification trees identified age, trip length, previous travel experience and having experienced a sports injury in the past year as the most important discriminatory variables for health threats.

CONCLUSIONS

Our study offers a revolutionary look at an almost real-time timeline of health events and behaviours during travel using mHealth technology. Non-infectious disease related health issues were common in this cohort, despite being largely unaddressed in traditional travel medicine research and suggest a substantial potential for improving evidence-based travel medicine advice.
