Background: Healthcare demand is individuals' decision on the choice of healthcare utilisation. Healthcare demand and its determinants can identify reason for the rise of healthcare expenditure and to essentially identify influential determinants for cost reduction via demand analysis. This manuscript aims to review the demand for healthcare and its determinants. Materials and Methods: A scoping systematic review was conducted, searched through the domains of PubMed, ScienceDirect, and Google scholar, using keywords of "healthcare demand" AND "medical care" OR determinants AND "medical care" OR demand AND "medical care" OR demand AND "health services" OR determinants AND "medical care" OR factors AND demand AND "medical care". Full articles from 30 year-recent publications, related with demand for healthcare and its determinants as well as written in English are included. Reviewed articles were excluded from the result findings. Result: Initially, 327 articles were searched from the databases and an additional nine from other sources. Articles that were duplicated were removed. Then, 233 articles underwent primary screening based on titles and abstract. Following this, 75 articles underwent secondary review for eligibility and 20 articles were finally chosen and included as the final literature search. Healthcare demand was pertaining to healthcare utilisation based on types of healthcare providers and types of services provided, health status and also health expenditure. The determinants of healthcare demand were; age, gender, ethnicity, education, occupation, household income and size, marital status, family size, health status, health problems and duration, medical insurance coverage, medical and non-medical costs or price, health expenditure, distance to provider and waiting time. Conclusion: Healthcare demand's determinants can assist in resource allocation to be groupspecific. Moreover, the nation's health system is able to provide more effective care to the population. This will subsequently assist policymakers with evidence of demand-side evidences for a more effective pattern of health behaviour.
