[Medical Costs on Malaria in Henan Province and Analysis of the Influential Factors].

Objective: To analyze the costs for the diagnosis and treatment of malaria in Henan Province and the influential factors.

Methods: Malaria cases diagnosed in and reported by medical institutions in Henan Province from November 2013 to October 2014 were selected. General information and clinical information of those with further microscopic confirmation were also collected. The rank sum test for two or more independent samples and stepwise regression analysis were used to investigate the influential factors for medical costs.

Results: A total of 218 malaria cases were finally included, of whom 73.4% were from rural areas. On average, the medical costs for patients from rural areas and cities/towns were 1 503 yuan and 4 833 yuan respectively. The average medical cost per patient with first-visit in rural hospitals was 2 600 yuan, and that with first-visit in provincial hospitals was 7 800 yuan. The average medical costs for patients diagnosed in county/city-level hospitals and provincial hospitals were 1 022.5 yuan and 6 170 yuan, respectively. There was null cost for patients diagnosed at the first-visit, while for those diagnosed after 3 or more visits the average cost per patient was 5 621 yuan. Factors significantly associated with medical costs were the current living locality of patients, the hospital level of first-visit, the hospital level of diagnosis and the number of visits before diagnosis（P＜0.05）. Stepwise regression analysis showed that the hospital level of first-visit was the most important influential factor for medical cost, followed by the hospital level of diagnosis and the number of visits before diagnosis. The higher hospital levels of first-visit and diagnosis, the higher cost. The same applied to the number of visits before diagnosis.

Conclusion: There is an considerable correlation between medical cost and health seeking behavior in malaria patients.
