Background: Saudi Arabia's healthcare sector is growing at a hasty stride; nevertheless, the quality of healthcare consumption remains challenged by the growing caseload in free public health facilities. Insurance could ease this pressure by moving some healthcare demand to private facilities conditional on its ability to enact health-seeking behaviour. These potential effects remain under-investigated. Therefore, the aim of this study was to investigate whether health insurance nudges health-seeking behaviour using data from Saudi Arabia. Materials and Methods: The study used nationally representative secondary data, obtained from the Family Health Survey, conducted in 2018, in Saudi Arabia. Health-seeking behaviour was measured by individual attendance of medical check-up. To account for endogeneity due to non-random selection of individuals into insurance, the analysis employed the inverse propensity weighting and the instrumental variables methods. Results: The results revealed that health insurance leads to increased chances of going for medical check-up. The effects are higher amongst non-Saudi nationals relative to citizens. Furthermore, people who purchase personal health insurance schemes are more likely to go for checks-ups, followed by individuals provided by the private sector and government sector. Finally, the study found that insurance positively nudges hypertension, diabetes, and cholesterol specific medical check-ups.
Conclusion:The findings indicated the need for health policy to increase access to health insurance in Saudi Arabia. A notable policy response is the introduction of national health insurance coverage, which has already proven in other countries as an effective measure to attain universal access to improved health. Nevertheless, results from this study highlighted variations in demand for health seeking based on type of insurance with highest returns in personal insurance. Policy should leverage on this behaviour response by introducing insurance packages that share premiums with citizens to incentivise utilisation. The results can also be used to design policy responses to demand for insurance, in the entire Arabian Gulf region, since these countries have similar health financing mechanism with Saudi Arabia.
