Effects of Different Payment Schemes on Actual Inpatient Expenditures with Schizophrenia

Abstract

This study analyzes actual inpatient expenditures by different health insurances for schizophrenic patients in Thailand. A total of 3,896 schizophrenia admissions at Khonkaen Rajanagarindra Psychiatric Hospital between January 2010 and December 2012 were included. Multivariate analysis of covariance analyses was conducted on schizophrenic patients among three health insurance schemes. Multiple-regression model was used to analyze the influence of variables on total inpatient expenditure. Ninety three percent of patients were paid by the Universal Coverage Scheme. After controlling for the length of stay, total expenditures were found to be 27,861.47, 15,199.23 and 15,063.05 Baht for the Civil Service Medical Benefit Scheme (CSMBS), Universal Coverage Scheme (UCS) and Social Security Scheme (SSS), respectively. The statistically significant difference for the CSMBS patients was found in the expenditures for hospital bed and board, medication, physical therapy, laboratory test as well as total expenditures. Longer hospital stay, higher education, number of admission, age and occupation were positively correlated to total expenditure.
