There was no change in the number of admissions to the intensive care units of patients transferred from smaller hospitals, but its percentage significantly decreased (P < .05), which may be a result of the significant increase in the total number of interhospital transfers, It was hypothesized that the universal coverage and a copayment contributed to these changes.en-USNational Health Insurance universal coverage copayment ED CARE COPAYMENTSjournal article
