Primary care payment models and avoidable hospitalizations in Ontario, Canada: A multivalued treatment effects analysis.

Improving access to primary care physicians' services may help reduce hospitalizations due to Ambulatory Care Sensitive Conditions (ACSCs). Ontario, Canada's most populous province, introduced blended payment models for primary care physicians in the early- to mid-2000s to increase access to primary care, preventive care, and better chronic disease management. We study the impact of payment models on avoidable hospitalizations due to two incentivized ACSCs (diabetes and congestive heart failure) and two non-incentivized ACSCs (angina and asthma). The data for our study came from health administrative data on practicing primary care physicians in Ontario between 2006 and 2015. We employ a two-stage estimation strategy on a balanced panel of 3710 primary care physicians (1158 blended-fee-for-service (FFS), 1388 blended-capitation models, and 1164 interprofessional team-based practices). First, we account for the differences in physician practices using a generalized propensity score based on a multinomial logit regression model, corresponding to three primary care payment models. Second, we use fractional regression models to estimate the average treatment effects on the treated outcome (i.e., avoidable hospitalizations). The capitation-based model sometimes increases avoidable hospitalizations due to angina (by 7 per 100,000 patients) and congestive heart failure (40 per 100,000) relative to the blended-FFS-based model. Switching capitation physicians into interprofessional teams mitigates this effect, reducing avoidable hospitalizations from congestive heart failure by 30 per 100,000 patients and suggesting better access to primary care and chronic disease management in team-based practices.

Predicting healthcare expenditure based on Adjusted Morbidity Groups to implement a needs-based capitation financing system.

BACKGROUND: Due to population aging, healthcare expenditure is projected to increase substantially in developed countries like Spain. However, prior research indicates that health status, not merely age, is a key driver of healthcare costs. This study analyzed data from over 1.25 million residents of Spain's Murcia region to develop a capitation-based healthcare financing model incorporating health status via Adjusted Morbidity Groups (AMGs). The goal was to simulate an equitable area-based healthcare budget allocation reflecting population needs. METHODS: Using 2017 data on residents' age, sex, AMG designation, and individual healthcare costs, generalized linear models were built to predict healthcare expenditure based on health status indicators. Multiple link functions and distribution families were tested, with model selection guided by information criteria, residual analysis, and goodness-of-fit statistics. The selected model was used to estimate adjusted populations and simulate capitated budgets for the 9 healthcare districts in Murcia. RESULTS: The gamma distribution with logarithmic link function provided the best model fit. Comparisons of predicted and actual average costs revealed underfunded and overfunded areas within Murcia. If implemented, the capitation model would decrease funding for most districts (up to 15.5%) while increasing it for two high-need areas, emphasizing allocation based on health status and standardized utilization rather than historical spending alone. CONCLUSIONS: AMG-based capitated budgeting could improve equity in healthcare financing across regions in Spain. By explicitly incorporating multimorbidity burden into allocation formulas, resources can be reallocated towards areas with poorer overall population health. Further policy analysis and adjustment is needed before full-scale implementation of such need-based global budgets.

Impact of capitation on physicians' behavior among patients with hypertension: an interrupted time series study in rural China.

OBJECTIVE: The purpose of this study is to explore the change in physicians' hypertension treatment behavior before and after the reform of the capitation in county medical community. METHODS: Spanning from January 2014 to December 2019, monthly data of outpatient and inpatient were gathered before and after the implementation of the reform in April 2015. We employed interrupted time series analysis method to scrutinize the instantaneous level and slope changes in the indicators associated with physicians' behavior. RESULTS: Several indicators related to physicians' behavior demonstrated enhancement. After the reform, medical cost per visit for inpatient exhibited a reverse trajectory (-53.545, 95%CI: -78.620 to -28.470, p < 0.01). The rate of change in outpatient drug combination decelerated (0.320, 95%CI: 0.149 to 0.491, p < 0.01). The ratio of infusion declined for both outpatient and inpatient cases (-0.107, 95%CI: -0.209 to -0.004, p < 0.1; -0.843, 95%CI: -1.154 to -0.532, p < 0.01). However, the results revealed that overall medical cost per visit and drug proportion for outpatient care continued their initial upward trend. After the reform, the decline of drug proportion for outpatient care was less pronounced compared to the period prior to the reform, and length of stay also had a similar trend. CONCLUSION: To some extent, capitation under the county medical community encourages physicians to control the cost and adopt a more standardized diagnosis and treatment behavior. This study provides evidence to consider the impact of policy changes on physicians' behavior when designing payment methods and healthcare systems aimed at promoting PHC.

Primary care services and emergency department visits in blended fee-for-service and blended capitation models: evidence from Ontario, Canada.

INTRODUCTION: It is well-known that the way physicians are remunerated can affect delivery of health care services to the population. Fee-for-service (FFS) generally leads to oversupply of services, while capitation leads to undersupply of services. However, little evidence exists on the link between remuneration and emergency department (ED) visits. We fill this gap using two popular blended models introduced in Ontario, Canada: the Family Health Group (FHG), an enhanced/blended FFS model, and Family Health Organization (FHO), a blended capitation model. We compare primary care services and rates of emergency department ED visits between these two models. We also evaluate whether these outcomes vary by regular- and after-hours, and patient morbidity status. METHODS: Physicians practicing in an FHG or FHO between April 2012 and March 2017 and their enrolled adult patients were included for analyses. The covariate-balancing propensity score weighting method was used to remove the influence of observable confounding and negative-binomial and linear regression models were used to evaluate the rates of primary care services, ED visits, and the dollar value of primary care services delivered between FHGs and FHOs. Visits were stratified as regular- and after-hours. Patients were stratified into three morbidity groups: non-morbid, single-morbid, and multimorbid (two or more chronic conditions). RESULTS: 6184 physicians and their patients were available for analysis. Compared to FHG physicians, FHO physicians delivered 14% (95% CI 13%, 15%) fewer primary care services per patient per year, with 27% fewer services during after-hours (95% CI 25%, 29%). Patients enrolled to FHO physicians made 27% more less-urgent (95% CI 23%, 31%) and 10% more urgent (95% CI 7%, 13%) ED visits per patient per year, with no difference in very-urgent ED visits. Differences in the pattern of ED visits were similar during regular- and after-hours. Although FHO physicians provided fewer services, multimorbid patients in FHOs made fewer very-urgent and urgent ED visits, with no difference in less-urgent ED visits. CONCLUSION: Primary care physicians practicing in Ontario's blended capitation model provide fewer primary care services compared to those practicing in a blended FFS model. Although the overall rate of ED visits was higher among patients enrolled to FHO physicians, multimorbid patients of FHO physicians make fewer urgent and very-urgent ED visits.

Financial incentives and health provider behaviour: Evidence from a capitation policy in Ghana.

The capitation payment model has been used as a supply-side cost-containment tool in controlling physician behaviour. However, little is known regarding its effectiveness in controlling costs and discouraging use of low-value care. This study seeks to examine whether financial incentives in capitation influence provider behaviour, and if so, whether such behaviour compromises outcomes for inpatients with hypertension. To this end, we evaluate the effect on outpatient visits and inpatient outcomes of the introduction of capitation into a mixed payment system involving diagnosis-related groups and fee-for-service in the Ashanti region of Ghana. We use difference-in-differences with fixed effects and event study analysis of claims data over 48 months (2016-2019). We found that providers responded to financial incentives in capitation; outpatient visits were approximately 35% lower. However, we found no significant impact of capitation on inpatient outcomes; that is, the in-hospital death rate did not increase, and the length of hospital stay (which may be a rough indicator of the severity of illness) also did not increase. These findings indicate that patient health outcomes did not deteriorate. Evidence suggests that the observed reduction in outpatient visits may be in unnecessary or low-value visits, especially at lower levels of the healthcare system.

Impact of capitation prepayment on the medical expenses and health service utilization of patients with coronary heart disease: a community policy intervention program in a county in China.

BACKGROUND: Medical costs have been rising rapidly in recent years, and China is controlling medical costs from the perspective of health insurance payments. OBJECTIVES: To explore the impact of the capitation prepayment method on medical expenses and health service utilization of coronary heart disease (CHD) patients, which provides a scientific basis for further improvement of the payment approach. METHODS: The diagnosis records of visits for CHD in the database from 2014 to 2016 (April to December each year) were selected, and two townships were randomly selected as the pilot and control groups. Propensity score matching (PSM) and difference-in-difference (DID) model were used to assess changes in outpatient and inpatient expenses and health service utilization among CHD patients after the implementation of the capitation prepayment policy. RESULTS: There were eventually 3,900 outpatients and 664 inpatients enrolled in this study after PSM. The DID model showed that in the first year of implementing the reform, total outpatient expenses decreased by CNY 13.953, drug expenses decreased by CNY 11.289, as well as Medicare payments decreased by CNY 8.707 in the pilot group compared to the control group. In the second year of implementing the reform, compared with the control group, the pilot group had a reduction of CNY 3.123 in other expenses, and a reduction of CNY 6.841 in Medicare payments. There was no significant change in inpatient expenses in the pilot group compared to the control group, but there was an increase of 0.829 visits to rural medical institutions, and an increase of 0.750 visits within the county for inpatients. CONCLUSIONS: The capitation prepayment method has been effective in controlling the outpatient expenses of CHD patients, as well as improving the medical service capacity of medical institutions within the Medical Community, and increasing the rate of inside county visits for inpatients.

Association Between Capitated Payments and Preventive Care Among U.S. Adults.

Introduction: There is increasing interest in using capitation rather than fee for service to promote primary care and population health. The goal of this study was to examine the association between practice reimbursement mix (majority fee for service versus majority capitation versus other) and receipt of common preventive screening examinations and health counseling from 2012 to 2018. Methods: Using the National Ambulatory Medical Care Survey, a retrospective cross-sectional study of 24,864 visits with primary care clinicians among patients aged 18-75 years without a cancer diagnosis was conducted. The main dependent measures were age- and sex-appropriate receipt of breast cancer screening, osteoporosis screening, cervical cancer screening, chlamydia testing, colon cancer screening, diabetes screening, and hyperlipidemia screening as well as 3 health counseling items. Multivariable logistic regression was performed to assess the association between reimbursement mix and receipt of preventive care, adjusted for patient, visit, and practice characteristics. Results: Majority capitation reimbursement was associated with a greater likelihood of receiving breast cancer screening (AOR=2.11, 95% CI=1.16, 3.84, p=0.014) and osteoporosis screening (AOR=4.34, 95% CI=1.74, 10.8, p=0.0017) than majority fee-for-service or other reimbursement mixes. Reimbursement mix was not associated with the likelihood of receiving 9 other preventive care or health counseling services. Conclusions: Larger amounts of capitation reimbursement may improve some but not all aspects of preventive care compared with fee for service.

Exploring the Challenges for Universal Health Coverage: A Call to Africa by AfroPHC.

The primary health care (PHC) system in Africa faces many challenges AND opportunities. To date, human resources for health in PHC are grossly insufficient in number, often inefficiently and inequitably distributed, lacking adequate training for delivering fully responsive and comprehensive frontline care and are treated inequitably within the health system. There has been a lack of solidarity among key role players in healthcare to create adequate PHC funding in Africa. Resources do not appropriately or adequately reach the frontline PHC service platform due to outdated service delivery and payment models. Patients experience PHC as numbers in a queue, with poor comprehensiveness, continuity, and coordination. Health workers are also treated like numbers in a bureaucracy that fragments and undermines training and service for integrated care around patient and population needs. However, opportunities abound with global PHC milestones, increasing political will for investment in PHC, and proven mechanisms for achieving a stronger workforce such as community health workers, clinical task-sharing, and the integration of family doctors into PHC. The African Forum for PHC (AfroPHC) has a vision for PHC and UHC that is team-based with skills mix appropriate to Africa, including family doctors, family nurse practitioners, clinical officers, community health workers and others that are empowered to take care of an empaneled population in high-quality people centred PHC. AfroPHC is making a call on stakeholders to develop and implement a regional forward-looking plan to 1) build robust PHC systems, 2) train, recruit and maintain a sufficient frontline PHC workforce, and 3) support PHC with appropriate financing. This can all come together easily in a nationally defined PHC contract using risk-adjusted blended capitation payment to decentralised PHC teams empanelled to enrolled populations, coordinated by district health services and easily administered at national or sub-national level for empowered public and private providers.

Loss ratio of the capitation payment unit of the health-promoting entities in Colombia between 2017 and 2021: a financial-actuarial approach.

BACKGROUND: Because of a change of government, the Colombian Ministry of Health and Social Protection is in the process of presenting a structural reform for the General System of Social Security in Health (GSSSH), in order to implement a 'preventive and predictive health model'. However, it will always be relevant to review and analyze the fiscal implications of any proposed public policy program, to protect financial sustainability and to promote the better functioning of the system in question. METHODS: To contribute to this topic, we have calculated, using a financial-actuarial approach, the loss ratio for the years 2017 to 2021 for the Capitation Payment Unit (CPU) for all the Health-Promoting Entities (HPE) for both contributory and subsidized schemes. This information, derived from public reports available on the official website of the National Health Superintendency, allows us to estimate the financial burden of the institutions that guarantee access to and provision of health services and technologies in Colombia. RESULTS: The study shows that close to half of the HPEs in Colombia (which represent 11.6 million affiliates) have CPU loss ratios of more than 100% for the year 2021, evidencing insufficient resources for the operation of health insurance. CONCLUSIONS: Finally, we propose some policy recommendations regarding the strengthening of informed decision-making to allow the healthy financial sustainability of the Colombian GSSSH.

County Hospital Responses to Funding Reforms in Zhejiang, China: An Interrupted Time-Series Analysis.

This study aimed to assess the effects of a two-stage funding reform, involving DRGs-based (Diagnostic Related Groups) payments for inpatient care and capitation funding for outpatient care, respectively, on services volume and care expenditure of county hospitals in Zhejiang province, China. A quasi-experimental design was adopted, involving 6 hospitals from 2 counties in the intervention group and 12 hospitals from 5 counties in the control group. The DRGs-based payments for inpatient care and capitation funding for outpatient care were introduced in January 2018 and January 2019, respectively. Controlled interrupted time-series analyses were performed to determine the effects of the funding reforms using monthly data over the period from January 2017 to December 2019. The volume of inpatient care decreased after the introduction of the first-stage DRGs-based payments, which was accompanied by an increase in the volume of outpatient visits. The DRGs-based payments led to a reduction of on average 1390 Yuan total expenditure per episode of inpatient care and 1116 Yuan out-of-pocket (OOP) payment per episode of inpatient care. However, the average outpatient expenditure per visit increased. So did the corresponding OOP payment per outpatient visit. The introduction of the second-stage capitation funding for outpatient care reversed the increasing trend of outpatient care. The average expenditure and OOP payment per outpatient visit decreased. The funding reforms create a significant effect on service volumes and expenditures in county hospitals. A coordinated approach to both inpatient and outpatient funding mechanisms is needed to minimize cost-shifting between inpatient and outpatient care and to achieve the intended policy outcomes.

Global landscape of community pharmacy services remuneration: a narrative synthesis of the literature.

Community pharmacists form a vital part of the health system all around the globe. Pharmacy remuneration models are aimed to ensure that pharmacies are sustained, and pharmacists could provide cost-effective services to the patients. This review summarizes the pharmacy services remuneration systems from different parts of the globe. Some countries have well-established reimbursement systems that recognize and compensate community pharmacies for their services, others are in the process of expanding the scope of reimbursable services. It further concludes by highlighting the ongoing efforts to incorporate pharmacist-provided services into reimbursement schemes and the need for standardized and consistent approaches to pharmacy remuneration globally.

Lifestyle Medicine: Overcoming Systemic and Cultural Barriers to Better, More Affordable Care.

The 6 pillars of lifestyle medicine have strong scientific backing and plenty of supportive evidence to validate their integration into routine clinical practice. However, two barriers stand in the way of their widespread adoption: the system of healthcare and the culture of medicine. This article describes changes necessary to overcome these systemic and cultural obstacles and outlines steps necessary to achieve what traditional healthcare has so-far failed to deliver: higher quality, lower costs, and greater access to care.

Increasing capitation in mixed remuneration schemes: Effects on service provision and process quality of care.

Many health systems apply mixed remuneration schemes for general practitioners, but little is known about the effects on service provision of changing the relative mix of fee for services and capitation. We apply difference-in-differences analyses to evaluate a reform that effectively reversed the mix between fee for services and capitation from 80/20 to 20/80 for patients with type 2 diabetes. Our results show reductions in provision of both the contact services that became capitated and in other non-capitated (still-billable) services. Reduced provision also occurred for guideline-recommended process quality services. We find that the effects are mainly driven by patients with co-morbidities and by general practitioners with high income, relatively many diabetes patients, and solo practitioners. Thus, increasing capitation in a mixed remuneration schemes appears to reduce service provision for patients with type 2 diabetes monitored in general practice with a risk of unwanted quality effects.

Implant Selection Strategies for Total Joint Arthroplasty: The Effects on Cost Containment and Physician Autonomy.

BACKGROUND: With continued declines in reimbursement for total joint arthroplasty, health systems have explored implant cost containment measures to generate sustainable margins. This review evaluated how implementation of (1) implant price control programs, (2) vendor purchasing agreements, and (3) bundled payment models affected implant costs and physician autonomy in implant selection. METHODS: PubMed, EBSCOhost, and Google Scholar were searched to identify studies that evaluated the efficacy of total hip or total knee arthroplasty implant selection strategies. The review included publications between January 1, 2002, and October 17, 2022. The mean Methodological Index for Nonrandomized Studies score was 18.3 ± 1.8. RESULTS: A total of 13 studies (32,197 patients) were included. All studies implementing implant price capitation programs found decreased implant costs, ranging 2.2 to 26.1% and increased utilization of premium implants. Most studies found bundled payments models reduced total joint arthroplasty implant costs with greatest reduction being 28.9%. Additionally, while absolute single vendor agreements had higher implant costs, preferred single vendor agreements had reduced implant costs. When given price constraints, surgeons tended to select more premium implants. CONCLUSION: Alternative payment models that incorporated implant selection strategies saw reduced costs and surgeon utilization of premium implants. The study findings encourage further research on implant selection strategies, which must balance the goals of cost containment with physician autonomy and optimized patient care. LEVEL OF EVIDENCE: Level III.

Effects of performance-based capitation payment on the use of public primary health care services in Indonesia.

The Indonesian national health insurance agency BPJS Kesehatan, the largest single-payer system in the world, is among the first to combine capitation-based payments with performance-based financing. The Kapitasi Berbasis Komitmen (KBK) scheme for puskesmas (community health centres) was implemented in province capitals between August 2015 and May 2016. Its main goal was to incentivize the substitution of secondary by primary care use. We evaluate its effect on its three incentivized outcomes: the fraction of insured visiting the puskesmas, the fraction of chronically ill with a puskesmas visit and the hospital referral rate for insured with a non-specialistic condition. We use BPJS Kesehatan claims data from 2015 to 2016 from a stratified one percent sample of its members. Comparable control districts were identified using coarsened exact matching. We adopt a Difference-in-Differences (DID) study design and estimate a two-way fixed effects regression model to compare 27 intervention districts to 300 comparable non-capital control districts. We find that KBK payment increased the monthly percentage of enrolees contacting a puskesmas with 0.578 percentage points. This is a sizeable increase of 48 percent compared to the baseline rate of just 1.2% but it still leaves most puskesmas far below the "sufficient" KBK threshold of 15%. For chronically ill patients, a small increase of 1.15 percentage points was estimated, but it leaves the rate even further below the program's "sufficient" threshold of 50%. We find no statistically significant effect on referral rates to hospitals for conditions not requiring specialist care. While we find positive effects of KBK on two out of three outcomes, all estimated effect sizes leave the actual rates far below the program targets. Our findings suggest that the KBK performance-based capitation reform has not been very successful in substituting secondary care use by greater primary care use.

Optimizing Physician Payment for a Single-Payer Healthcare System.

Current forms of payment of independent physicians in U.S. health care may incentivize more care (fee-for-service) or less care (capitation), be inequitable across specialties (resource-based relative value scale [RBRVS]), and distract from clinical care (value-based payments [VBP]). Alternative systems should be considered as part of health care financing reform. We propose a "Fee-for-Time" approach that would pay independent physicians using an hourly rate based on years of necessary training applied to time for service delivery and documentation. RBRVS overvalues procedures and undervalues cognitive services. VBP shifts insurance risk onto physicians, introducing incentives to game performance metrics and to avoid potentially expensive patients. The administrative requirements of current payment methods introduce large administrative costs and undermine physician motivation and morale. We describe a Fee-for-Time payment scenario. A combination of single-payer financing and payment of independent physicians using the Fee-for-Time proposal would be simpler, more objective, incentive-neutral, fairer, less easily gamed, and less expensive to administer than any system with physician payment based on fee-for-service using RBRVS and VBP.

Impacts of Outpatient Payment Reforms on Volume and Expenditures in Public Hospitals: Evidence from a Quasi-Experimental Analysis in Zhejiang, China.

Purpose: China developed an innovative episode-based payment scheme for outpatient care, namely "Ambulatory Patient Groups (APGs) + capitation" payment, to constrain inflation in outpatient expenditures. This study aimed to assess the effects of this payment method on volume and expenditures in Chinese public hospitals. Methods: A quasi-experimental study was conducted with 7 municipal and 12 county hospitals from Jinhua as the intervention group and 15 municipal and 24 county hospitals from three neighbouring cities as the control group. The payment reform was introduced to municipal and county hospitals in the intervention group in January 2020 and January 2021, respectively. Monthly data on volumes and outpatient expenditures were collected from each hospital from January 2019 to December 2021. Controlled interrupted time-series analyses were performed to determine the effects of the funding reforms. Results: Outpatient visits in municipal hospitals decreased by 1417.54 (p=0.048) per month on average compared with control ones after the reform was implemented, whilst that in county hospitals increased by 1058.04 (p=0.041) per month on average. The trend of drug expenditures (ß 7=-1.41, p=0.019) in municipal hospitals dropped, which was accompanied by an immediate reduction in consumable expenditures (ß 6 =-6.89, p=0.044). The funding reform also led to the significant declines in drug (ß 6=-10.96, p=0.009) and consumable (ß 6=-4.78, p=0.041) expenditures in county hospitals. Municipal hospitals experienced the drop in the trend of total outpatient expenditures (ß 7=-3.99, p=0.018) over the same period. Conclusion: The strength of the "AGPs + capitation" payment for outpatient care lies in its ability to control the excessive growth of medical expenses through correcting inappropriate incentives. However, minimising potential cost-shifting and risk-shifting to uninsured service items should be given attention.

A Causal View of the Role and Potential Limitations of Capitation in Promoting Whole Health System Performance.

For several decades, health systems in developed countries have faced rapidly rising healthcare costs without concomitant improvements in health outcomes. Fee for service (FFS) reimbursement mechanisms (RMs), where health systems are paid based on volume, contribute to this trend. In Singapore, the public health service is trying to curb rising healthcare costs by transitioning from a volume-based RM to a capitated payment for a population within a geographical catchment area. To provide insight into the implications of this transition, we developed a causal loop diagram (CLD) to represent a causal hypothesis of the complex relationship between RM and health system performance. The CLD was developed with input from government policymakers, healthcare institution administrators, and healthcare providers. This work highlights that the causal relationships between government, provider organizations, and physicians involve numerous feedback loops that drive the mix of health services. The CLD clarifies that a FFS RM incentivizes high margin services irrespective of their health benefits. While capitation has the potential to mitigate this reinforcing phenomenon, it is not sufficient to promote service value. This suggests the need to establish robust mechanisms to govern common pool resources while minimizing adverse secondary effects.

Behavioral Impact on Clinical Specialist Payment Method: A Systematic Review.

Background: With growing healthcare (HC) expenditures and limited funding, policymakers need to find new ways to provide healthcare that is affordable and fair. There are many methods for paying specialists, and the three basic payment methods include fee-for-service (FFS), capitation, and salary. This review focuses on identifying published articles related to the different methods used for paying specialists for their service and further highlights their advantages and disadvantages. Methods: The research was designed and carried out in line with the "Preferred Reporting Items for Systematic Reviews and Meta-Analysis" (PRISMA) checklist. Five databases were used in the literature search ie: Scopus, Web of Science, Ovid Medline, EBSCOhost, and PubMed in 2020. The search term used revolved around physician, payment method and specialist behavior. Results: Databases were searched electronically using EndNote X9.2, wherein 588 related studies of literature were included. Meanwhile, it went down to 546 related studies after the title and abstract screening was conducted in order to eliminate duplicates. In total, 24 studies were then left to be reviewed in full text; finally, 12 studies were integrated into this analysis after a description of the entire text of the studies. Conclusion: Payment methods can affect physician practice behaviors and the quality of healthcare. The combination of payment methods may, however, combine the benefits of simple payment methods. Where there is not adequate mixing of methods, bonus-for-performance programs may encourage the provision of targeted services. Thus, before a new medical policy is implemented, policymakers must define and empirically examine the positive and negative impacts.

The effect of the capitation policy withdrawal on maternal health service provision in Ashanti Region, Ghana: an interrupted time series analysis.

BACKGROUND: Payment methods are known to influence maternal care delivery in health systems. Ghana suspended a piloted capitation provider payment system after nearly five years of implementation. This study aimed to examine the effects of Ghana's capitation policy on maternal health care provision as part of lesson learning and bridging this critical literature gap. METHODS: We used secondary data in the District Health Information Management System-2 and an interrupted time series design to assess changes in level and trend in the provision of ANC4+ (visits of pregnant women making at least the fourth antenatal care attendance per month), HB36 (number of hemoglobin tests conducted for pregnant women who are at the 36th week of gestation) and vaginal delivery in capitated facilities-CHPS (Community-based Health Planning and Services) facilities and hospitals. RESULTS: The results show that the capitation policy withdrawal was associated with a statistically significant trend increase in the provision of ANC4+ in hospitals (coefficient 70.99 p < 0. 001) but no effect in CHPS facilities. Also, the policy withdrawal resulted in contrasting effects in hospitals and CHPS in the trend of provision of Hb36; a statistically significant decline was observed in CHPS (coefficient - 7.01, p < 0.05) while that of hospitals showed a statistically significant trend increase (coefficient 32.87, p < 0.001). Finally, the policy withdrawal did not affect trends of vaginal delivery rates in both CHPS and hospitals. CONCLUSIONS: The capitation policy in Ghana appeared to have had a differential effect on the provision of maternal services in both CHPS and hospitals; repressing maternal care provision in hospitals and promoting adherence to anemia testing at term for pregnant women in CHPS facilities. Policy makers and stakeholders should consider the possible detrimental effects on maternal care provision and quality in the design and implementation of per capita primary care systems as they can potentially impact the achievement of SDG 3.
