Health Insurance Deductibles and Health Care-Seeking Behaviors in a Consumer-Driven Health Care System With Universal Coverage.

ABSTRACT:

Importance

Characteristics of a health care system can facilitate forgoing of health care owing to economic reasons and can influence population health. Whether health insurance deductibles are associated with forgoing of health care in a consumer-driven health care system with universal coverage, such as the Swiss health system, remains to be determined.

Objective

To assess the association between insurance plan deductibles and forgoing of health care with consideration of socioeconomic factors.

Design, setting, and participants

This cross-sectional study was conducted in Geneva, Switzerland, using data collected from January 1, 2007, to December 31, 2019. Population-based samples were obtained yearly through random stratified sampling by age and sex of the general population aged 20 to 74 years. Participants were invited to an appointment at 1 of the 3 study sites in Geneva, where they completed a sociodemographic and health questionnaire.

Exposures

Insurance plan deductible level.

Main outcomes and measures

The main outcome was forgoing of health care owing to economic reasons. Unadjusted and multivariable Poisson models were used to assess the association between deductible level and forgoing of health care. Differences in forgoing health care across the range of health insurance deductibles or household income levels were quantified using the relative index of inequality (RII).

Results

The study group included 11 872 participants (5974 [50.3%] male; median age, 48.1 years [interquartile range, 38.7-59.1 years]); 1146 (9.7%) reported forgoing health care. Participants with high-deductible plans reported forgoing health care more frequently than those with low-deductible plans (331 [13.5%] vs 591 [8.7%]). In adjusted analysis, higher-deductible plans were associated with a greater likelihood of forgoing health care (RII, 2.2; 95% CI, 1.7-3.0; P < .001) independently of socioeconomic status, known comorbidities, and cardiovascular risk factors. Deductible level was associated with forgoing of health care among participants younger than 40 years (RII, 2.5; 95% CI, 1.6-4.0; P < .001) and those aged 40 to 64 years (RII, 1.9; 95% CI, 1.3-2.9; P = .002) but not among those older than 65 years (RII, 2.9; 95% CI, 0.8-10.4; P = .11).

Conclusions and relevance

In this cross-sectional study, high insurance plan deductibles were associated with forgoing of health care independent of socioeconomic status and preexisting conditions in a universal consumer-driven health care system with good population outcomes in Switzerland. Uncovering health care system design features that could lead to suboptimal population care may help decision makers improve their current health care system design to achieve better outcomes.

Project description:BackgroundAlthough tuberculosis (TB) patients often incur high costs to access TB-related services, it was unclear beforehand whether the implementation of universal health coverage (UHC) in Indonesia in 2014 would reduce direct costs and change the pattern of care-seeking behaviour. After its introduction, we therefore assessed TB patients' care-seeking behaviour and the costs they incurred for diagnosis, and the determinants of both.MethodsIn this cross sectional study, we interviewed adult TB patients in urban, suburban, and rural districts of Indonesia in July-September 2016. We selected consecutively patients who had been treated for TB in primary health centers for at least 1 month until we reached at least 90 patients in each district. After establishing which direct and indirect costs they had incurred during the pre-diagnostic phase, we calculated the total costs (in US Dollars). To identify the determinants of these costs, we applied a general linear mixed model to adjust for our cluster-sampling design.ResultsNinety-three patients of the 282 included in our analysis (33%) first sought care at a private clinic. The preference for such clinics was higher among those living in the rural district (aOR 1.88, 95% CI 0.85-4.15, P?=?0.119) and among those with a low educational level (aOR 1.69, 95% CI 0.92-3.10, P?=?0.090). Visiting a private clinic as the first contact also led to more visits (? 0.90, 95% CI 0.57-1.24, P?<?0.001) and higher costs than first visiting a Primary Health Centre, both in terms of direct costs (??=?16.87, 95%CI 10.54-23.20, P?<?0.001) and total costs (??=?18.41, 95%CI 10.35-26.47, P?<?0.001).ConclusionDespite UHC, high costs of TB seeking care remain, with direct medical costs contributing most to the total costs. First seeking care from private providers tends to lead to more pre-diagnostic visits and higher costs. To reduce diagnostic delays and minimize patients' costs, it is essential to strengthen the public-private mix and reduce the fragmented system between the national health insurance scheme and the National TB Programme.

Project description:ObjectivesTo analyse the relationship between health need, insurance coverage, health service availability, service use, insurance claims and out-of-pocket spending on health across Indonesia.DesignSecondary analysis of nationally representative quantitative data. We merged four national data sets: the National Socioeconomic Survey 2018, National Census of Villages 2018, Population Health Development Index 2018 and National Insurance Records to end 2017. Descriptive analysis and linear regression were performed.SettingIndonesia has one of the world's largest single-payer national health insurance schemes. Data are individual and district level; all are representative for each of the country's 514 districts.ParticipantsAnonymised secondary data from 1 131 825 individual records in the National Socioeconomic Survey and 83 931 village records in the village census. Aggregate data for 220 million insured citizens.Primary outcome measuresHealth service use and out-of-pocket payments, by health need, insurance status and service availability. Secondary outcome: insurance claims.ResultsSelf-reported national health insurance registration (60.6%) is about 10% lower compared with the insurer's report (71.1%). Insurance coverage is highest in poorer areas, where service provision, and thus service use and health spending, are lowest. Inpatient use is higher among the insured than the uninsured (OR 2.35, 95% CI 2.27 to 2.42), controlling for health need and access), and poorer patients are most likely to report free inpatient care (53% in wealth quintile 1 vs 41% in Q5). Insured patients spend US$ 3.14 more on hospitalisation than the uninsured (95% CI 1.98 to 4.31), but the difference disappears when controlled for wealth. Lack of services is a major constraint on service use, insurance claims and out-of-pocket spending.ConclusionsThe Indonesian public insurance system protects many inpatients, especially the poorest, from excessive spending. However, others, especially in Eastern Indonesia cannot benefit because few services are available. To achieve health equity, the Indonesian government needs to address supply side constraints and reduce structural underfunding.

Project description:BACKGROUND:Kisiizi Hospital Health Insurance scheme started in 1996 to; improve access to health services, and provide a stable source of funding and reduce bad debts to Kisiizi hospital. Objectives of this study were; to describe Kisiizi Hospital Health Insurance scheme and to document lessons learned and implications for universal health coverage. METHODS:This was a descriptive cross-sectional study. Data from different sources were triangulated and thematically analysed. RESULTS:Most households (96%) were organized in Engozi societies (e-Societies), met monthly, and made financial contributions. Cultural solidarity in e-Societies provided a platform for the Kisiizi hospital health insurance scheme establishment, operation and made it compulsory for members. e-Societies disciplinary measures and fear of high out-of-pocket payment for health care enforced enrolment, retention and increased membership. Community sensitisation and community participation in setting premiums and co-payments provided for better understanding of health insurance and rendered them acceptable, affordable and equitable. Membership increased from 330 in 1996 to 38,400 families in 2017. Kisiizi hospital health insurance scheme covered only health services obtained from Kisiizi hospital. Kisiizi hospital health insurance scheme offered no exemption, credit and referral facilities. e-Societies sometimes paid premiums for members from savings and offered them loans to. Kisiizi hospital provided good quality health services, which were easily accessed by insured members. Kisiizi hospital got a stable source of funding and reduced debt burden. CONCLUSIONS:Kisiizi hospital health insurance scheme improved access to health services, provided a stable source of funding and reduced bad debts to the hospital. Internal and external factors to e-Society enforced enrolment and retention of members in Kisiizi hospital health insurance scheme. Good quality health services at Kisiizi hospital demonstrated value for money and offered incentives for enrolment and retention, and coverage expansion. Community sensitization and participation in setting premiums and co-payments rendered Kisiizi hospital health insurance scheme acceptable, affordable and catered for equity. Insured members enjoyed benefits; protection against catastrophic health spending, impoverishment, and easy access to quality health care.

Project description:BACKGROUND:Kenya has prioritized the attainment of universal health coverage (UHC) through the expansion of health insurance coverage by the National Hospital Insurance Fund (NHIF). In 2015, the NHIF introduced reforms in premium contribution rates, benefit packages, and provider payment methods. We examined the influence of these reforms on NHIF's purchasing practices and their implications for strategic purchasing and health system goals of equity, efficiency and quality. METHODS:We conducted an embedded case study with the NHIF as the case and the reforms as embedded units of analysis. We collected data at the national level and in two purposively selected counties through 41 in-depth interviews with health financing stakeholders, facility managers and frontline providers; 4 focus group discussions with 51 NHIF members; and, document reviews. We analysed the data using a Framework approach. RESULTS:The new NHIF reforms were characterized by weak purchasing actions. Firstly, the new premium contribution rates were inadequately communicated and unaffordable for certain citizen groups. Secondly, while the new benefit packages were reported to be based on service needs, preferences and values of the population, they were inadequately communicated and unequally distributed across different citizen groups. In addition, the presence of service delivery infrastructure gaps in public healthcare facilities and the pro-urban and pro-private distribution of contracted health facilities compromised delivery of, and access to, these new services. Lastly, the new provider payment methods and rates were considered inadequate, with delayed payments and weak links to financial accountability mechanisms which compromised their ability to incentivize equity, efficiency and quality of healthcare delivery. CONCLUSION:While NHIF sought to expand population and service coverage and reduce out-of-pocket payments with the new reforms, weaknesses in the reforms' design and implementation limited NHIF's purchasing actions with negative implications for the health system goals of equity, efficiency and quality. For the reforms to accelerate the country's progress towards UHC, policy makers at the NHIF and, national and county government should make deliberate efforts to align the design and implementation of such reforms with strategic purchasing actions that are aimed at improving health system goals.
