In China, Health Care Utilization Increases at Retirement, a New Study Shows
Around the world, societies are aging at a rapid pace. The demographic transition and the challenges surrounding elderly care are defining issues of our time. Aging populations strain public finances and existing models of social support, affect economic growth, and change disease patterns and prevalence. Many countries, therefore, contemplate policy changes to their retirement, pensions, and health care systems. China, which faces a fast-growing trend of aging cohorts, is no exception.
To alleviate the pressure of elderly care on public finances, the Chinese government has been considering raising retirement ages and corresponding changes in social health insurance and pension policy. A new study now helps evaluate such retirement reforms and provides evidence to inform policy in China and elsewhere by probing the effects of retirement on health care utilization.

The study’s co-authors, including Karen Eggleston, director of the Asia Health Policy Program at APARC, leverage administrative data from medical claims for over 80,000 insured adults in a megacity in eastern China to explore the effect of retirement on outpatient and inpatient care utilization. In this case, urban employee insurance beneficiaries receive a reduced patient cost-sharing rate upon retirement. By focusing on a relatively well-insured population with comprehensive administrative data on insurance plan design and overall resource use at retirement, the study provides new evidence about mechanisms such as the reduced out-of-pocket price of health care, the opportunity cost of time, and the interaction of these demand-side factors with supply-side incentives. Eggleston and her colleagues report on their findings in the journal Health Economics.
In this relatively well-insured population, annual health care utilization significantly increases primarily because of more intensive use of outpatient care at retirement. This increase in outpatient care stems from a decline in the patient cost-sharing rate, the reduced time constraints upon retirement, and the interaction of these factors with supply-side incentives such as prescribing antibiotics. There is no evidence of change in inpatient care at retirement.
The economics of medical expenditure growth and its interaction with population aging is of considerable policy importance for countries in all income groups. “Our findings may provide useful evidence as one consideration for policymakers in other cities in China and elsewhere looking to increase insurance benefits and control medical spending for burgeoning elderly populations.

The study’s co-authors, including Karen Eggleston, find that health care expenditures among Chinese covered by relatively generous health insurance significantly increase at retirement, primarily due to an increase in the number of outpatient visits.
Healthcare Utilization at Retirement in China
Previous studies, mostly analyzing data from high-income economies, present mixed evidence on the relationship between retirement and healthcare utilization. This study leverages administrative data for over 80,000 urban Chinese workers to explore the effect of retirement on outpatient and inpatient care utilization using a fuzzy regression discontinuity design. The analyses of medical claims from a large city in China complement and extend the current literature by providing evidence of potential mechanisms underlying increased short-run utilization. In this relatively well-insured population, annual total healthcare expenditures significantly increase primarily because of more intensive use of outpatient care at retirement, especially at the right tail of the distribution of outpatient visits. This increase in outpatient care appears to stem from a decline in the patient cost-sharing rate and the reduced opportunity cost of time upon retirement, interacting with supplier-induced demand, not from any sudden impact on health. We do not find evidence of change in inpatient care at retirement. The results hold for both females and males and are robust to a number of sensitivity analyses.
COVID-19 Related Immunization Disruptions in Rajasthan, India
Introduction
Governments around the world suspended immunization outreach to control COVID-19 spread. Many have since resumed services with an emphasis on catch-up vaccinations. This paper evaluated immunization disruptions during India’s March-May 2020 lockdown and the extent to which subsequent catch-up efforts reversed them in Rajasthan, India.
Methods
In this retrospective observational study, we conducted phone surveys to collect immunization details for 2,144 children that turned one-year-old between January and October 2020. We used logistic regressions to compare differences in immunization timeliness and completed first-year immunization status among children that were due immunizations just before (unexposed), during (heavily exposed), and after (post-exposure) the lockdown.
Results
Relative to unexposed children, heavily exposed children were significantly less likely to be immunized at or before 9 months (OR 0.550; 95% CI 0.367–0.824; p = 0.004), but more likely to be immunized at 10–12 months (OR 1.761; 95% CI 1.196–2.591; p = 0.004). They were also less likely to have completed their key first-year immunizations (OR 0.624; 95% CI 0.478–0.816; p = 0.001) by the time of the survey. In contrast, post-exposure children showed no difference in timeliness or completed first-year immunizations relative to unexposed children, despite their younger age. First-year immunization coverage among heavily exposed children decreased by 6.9 pp to 10.4 pp (9.7% to 14.0%). Declines in immunization coverage were larger among children in households that were poorer, less educated, lower caste, and residing in COVID red zones, although subgroup comparisons were not statistically significant.
Conclusion
Disruptions to immunization services resulted in children missing immunization during the lockdown, but catch-up efforts after it was eased ensured many children were reached at later ages. Nevertheless, catch-up was incomplete and children due for their immunizations during the lockdown remained less likely to be fully immunized 4–5 months after it lifted, even as younger cohorts due for immunizations in June or later returned to pre-lockdown schedules.
Why Insurance Alone May Not Improve Women's Access To Healthcare
This article was first published by the social and political economy portal IndiaSpend.
Women from poor households made about 235,000 fewer hospital visits compared to men for seven gender-neutral disease categories between January 2017 and October 2019, a new study analyzing a Rajasthan state health insurance scheme has estimated. The Bhamashah Swasthya Bima Yojana aims to provide health insurance to about 46 million persons living below the poverty line, as a step towards universal and equitable access to healthcare in the state, per the study.
Pascaline Dupas and Radhika Jain of Stanford University studied data of insurance claims from 4.2 million hospital visits under the Bhamashah scheme from its launch in December 2015 till October 2019, and the study was published as a National Bureau of Economic Research working paper. The study was conducted in partnership with the Rajasthan state government.
Women made up 45% of hospital visits under the Bhamashah scheme between January 2017 and October 2019, though their share in the population is 48%, per the study. The gender gap is starker for girls and older women. The share of girls in children aged under 10 years who visited the hospital under this insurance program was 33%, though their share of this age group's population is 47%; among those aged above 50 years, women are 51%, yet their share of hospital visits under this insurance program was 43%.
"We were struck by this discrepancy in the data. We were not expecting such a large [gender] difference," Dupas, an economist and professor at Stanford University, told IndiaSpend. In most other developed countries for which such data have been analyzed, subsidized healthcare usually caters to those who otherwise don't have access to it, added Jain, a postdoctoral fellow in Asia Health Policy at Stanford University, US.

Women Left Behind: Rajasthan Health Insurance Scheme Has a Gender Gap
This opinion piece was first published in the economics and policy portal Ideas for India.
Equity in healthcare is a key goal of health policy in India. Analyzing administrative data from Rajasthan, this article highlights substantial gender gaps in the utilization of subsidized hospital care under the state health insurance program. These disparities persist despite substantial program expansion and seem to be driven by households being less willing to allocate resources to female vis-à-vis male health.
Over the past 15 years, India’s central government and numerous state governments have put in place health insurance programmes that entitle low-income households to free healthcare at public and empanelled private hospitals. Health equity and universal health coverage are explicit goals of these programs. In new research, we study gender equity in the Bhamashah Swasthya Bima Yojana (BSBY)1 health insurance program, which was launched in the state of Rajasthan in 2015, and is similar in design to the national Pradhan Mantri Jan Arogya Yojana (PMJAY).
Our starting point is a dataset of insurance claims filed for all 4.2 million hospital visits between 2015 and 2019, including patient age, gender, residence address, hospital visited, dates of admission and discharge, and service(s) received. We geo-coded hospital locations and patient addresses, which allowed us to calculate proximity to hospitals and the distance traveled for every hospital visit. Finally, we linked the insurance data to the 2011 Census and data on three rounds of village-level (gram panchayat) elections. To our knowledge, the dataset we compiled from these various sources is the first dataset of its type in India and allows us to study care-seeking under insurance with unusual granularity.
