Copayment and recommended strategies to mitigate its impacts on access to emergency medical services under universal health coverage: a case study from Thailand

Emergency Department Use Across Income Groups Following an Increase in Cost-Sharing

Importance

To encourage the appropriate utilization of emergency care, cost-sharing for emergency care was increased from HK$100 (US $12.8) to HK$180 (US $23.1) per visit in June 2017 in all public hospitals in Hong Kong. However, there are concerns that this increase could deter appropriate emergency department (ED) visits and be associated with income-related disparities.

Objective

To examine changes in ED visits after the fee increase.

Design, Setting, and Participants

This retrospective cohort study used administrative data from June 2015 to May 2019 from all public hospitals in Hong Kong. Participants included all Hong Kong residents aged 64 years and younger, categorized into low-income, middle-income, and high-income groups according to the median household income in their district of residence. Data analysis was performed from May to June 2023.

Main Outcomes and Measures

The primary outcome was the ED visit rate per 100 000 people per month, categorized into 3 severity levels (emergency, urgent, and nonurgent). Secondary outcomes include general outpatient (GOP) visit rate, emergency admission rate, and in-hospital mortality rate per month at public hospitals. Segmented regression analyses were used to estimate changes in the level and slope of outcome variables before and after the fee increase.

Results

This study included a total of 5 441 679 ED patients (2 606 332 male patients [47.9%]; 2 108 933 patients [38.5%] aged 45-64 years), with 2 930 662 patients (1 407 885 male patients [48.0%]; 1 111 804 patients [37.9%] aged 45-64 years) from the period before the fee increase. The fee increase was associated with an 8.0% (95% CI, 7.1%-9.0%) immediate reduction in ED visits after June 2017, including a 5.9% (95% CI, 3.3%-8.5%) reduction in urgent visits and an 8.9% (95% CI, 8.0%-9.8%) reduction in nonurgent visits. In addition, a 5.7% (95% CI, 4.7%-6.8%) reduction of emergency admissions was found, whereas no significant changes were observed in in-hospital mortality. Specifically, a statistically significant increase in GOP visits (4.1%; 95% CI, 0.9%-7.2%) was found within the low-income group, but this association became insignificant after controlling for the social security group, who were exempted from payment, as a control.

Conclusions and Relevance

In this cohort study, the fee increase was not associated with changes in ED visits for emergency conditions, but there was a negative and significant association with both urgent and nonurgent conditions across all income groups. Considering the marginal increase in public GOP services, further study is warranted to examine strategies to protect low-income people from avoiding necessary care.

Factors Associated with Willingness to Pay for Cost-Sharing under Universal Health Coverage Scheme in Yogyakarta, Indonesia: A Cross-Sectional Survey

BACKGROUND

National Health Insurance (NHI) in Indonesia requires an appropriate cost-sharing policy, particularly for diseases that require the largest financing. This study examined factors that influence willingness to pay (WTP) for cost-sharing under the universal health coverage scheme among patients with catastrophic illnesses in Yogyakarta, Indonesia.

METHODS

This was a cross-sectional study using structured questionnaires through direct interviews. The factors related to the WTP for cost-sharing under the NHI scheme in Indonesia were identified by a bivariable logistic regression analysis.

RESULTS

Two out of every five (41.2%) participants had willingness to pay for cost-sharing. Sex [AOR = 0.69 (0.51, 0.92)], education [AOR = 1.54 (0.67, 3.55)], family size [AOR = 1.71 (1.07, 2.73)], occupation [AOR = 1.35 (0.88, 2.07)], individual income [AOR = 1.50 (0.87, 2.61)], household income [AOR = 1.47 (0.90, 2.39)], place of treatment [AOR = 2.54 (1.44, 4.45)], a health insurance plan [AOR = 1.22 (0.87, 1.71)], and whether someone receives an inpatient or outpatient service [AOR = 0.23 (0.10, 0.51)] were found to affect the WTP for a cost-sharing scheme with p < 0.05.

CONCLUSION

Healthcare (place of treatment, health insurance plan, and whether someone receives an inpatient or outpatient service) and individual socioeconomic (sex, educational, family size, occupational, income) factors were significantly related to the WTP for cost-sharing.

Closing the Equity Gap of Access to Emergency Departments of Private Hospitals in Thailand

Background

Previous policy implementation in 2012 to incentivize private hospitals in Thailand, a country with universal health coverage, to provide free-of-charge emergency care using DRG-based payment resulted in an equity gap of access and copayment. To bridge the gap, strategic policies involving financial and legal interventions were implemented in 2017. This study aims to assess whether this new approach would be able to fill the gap.

Methods

We analyzed an administrative dataset of over 20,206 patients visiting private hospital EDs from April 2017 to October 2017 requested for the preauthorization of access to emergency care in the first 72 hours free of charge. The association between types of insurance and the approval status was explored using logistic regression equation adjusting for age, modes of access, systolic blood pressure, respiratory rate, and Glasgow coma scores.

Results and Discussion

The strategic policies implementation resulted in reversing ED payer mix from the most privileged scheme, having the major share of ED visit, to the least privileged scheme. The data showed an increasing trend of ED visits to private hospitals indicates the acceptance of the financial incentive. Obvious differences in degrees of urgency between authorized and unauthorized patients suggested the role of preauthorization as a barrier to the noncritical patient visiting the ED. Furthermore, our study depicted the gender disparity between authorized and unauthorized patients which might indicate a delay in care seeking among critical female patients. Lessons learned for policymakers in low-and-middle income countries attempting to close the equity gap of access to private hospital EDs are discussed.
