The role of GP's compensation schemes in diabetes care: evidence from panel data

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.

Effects of individual and neighborhood social risks on diabetes pay-for-performance program under a single-payer health system

BACKGROUND

Enrollment in and adherence to a diabetes pay-for-performance (P4P) program can lead to desirable processes and outcomes of diabetes care. However, knowledge is limited on the potential exclusion of patients with individual or neighborhood social risks or interruption of services in the disease-specific P4P program without mandatory participation under a single-payer health system.

OBJECTIVE

To investigate the impact of individual and neighborhood social risks on exclusion from and adherence to the diabetes P4P program of patients with type 2 diabetes (T2D) in Taiwan.

METHODS

This study used data from Taiwan's 2009-2017 population-based National Health Insurance Research Database, 2010 Population and Housing Census, and 2010 Income Tax Statistics. A retrospective cohort study was conducted, and study populations were identified from 2012 to 2014. The first cohort comprised 183,806 patients with newly diagnosed T2D, who had undergone follow up for 1 year; the second cohort consisted of 78,602 P4P patients who had undergone follow up for 2 years after P4P enrollment. Binary logistic regression models were used to examine the associations of social risks with exclusion from and adherence to the diabetes P4P program.

RESULTS

T2D patients with higher individual social risks were more likely to be excluded from the P4P program, but those with higher neighborhood-level social risks were slightly less likely to be excluded. T2D patients with the higher individual- or neighborhood-level social risks showed less likelihood of adhering to the program, and the person-level coefficient was stronger in magnitude than the neighborhood-level one.

CONCLUSIONS

Our results indicate the importance of individual social risk adjustment and special financial incentives in disease-specific P4P programs. Strategies for improving program adherence should consider individual and neighborhood social risks.

Expanding outpatient benefits package can reduce diabetes-related avoidable hospitalizations

Objective

To evaluate the policy effect of replacing hospitalization service with outpatient service and reducing diabetes-related avoidable hospitalizations by improving outpatient benefits package.

Methods

A database of hospital discharge from 2015 to 2017 in City Z was used. All diabetic inpatient cases enrolled in Urban Employee Basic Medical Insurance were selected as the intervention group, and diabetic inpatient cases enrolled in Urban and Rural Resident Basic Medical Insurance were selected as the control group. The Difference-in-Difference model was used to analyze the effect of improving outpatient benefits package level of diabetes from 1800 yuan (about $252.82) to 2400 yuan (about $337.09) per capita per year on avoidable hospitalization rate, average hospitalization cost and average length of stay.

Results

The avoidable hospitalization rate of diabetes mellitus decreased by 0.21 percentage points (P < 0.01), the average total cost of hospitalization increased by 7.89% (P < 0.01), and the average length of stay per hospitalization increased by 5.63% (P < 0.01).

Conclusions

Improving the outpatient benefits package of diabetes can play a role in replacing hospitalization service with outpatient service, reducing diabetes-related avoidable hospitalizations, and reducing the disease burden and financial burden.

Impact of prevention in primary care on costs in primary and secondary care for people with serious mental illness

A largely unexplored part of the financial incentive for physicians to participate in preventive care is the degree to which they are the residual claimant from any resulting cost savings. We examine the impact of two preventive activities for people with serious mental illness (care plans and annual reviews of physical health) by English primary care practices on costs in these practices and in secondary care. Using panel two-part models to analyze patient-level data linked across primary and secondary care, we find that these preventive activities in the previous year are associated with cost reductions in the current quarter both in primary and secondary care. We estimate that there are large beneficial externalities for which the primary care physician is not the residual claimant: the cost savings in secondary care are 4.7 times larger than the cost savings in primary care. These activities are incentivized in the English National Health Service but the total financial incentives for primary care physicians to participate were considerably smaller than the total cost savings produced. This suggests that changes to the design of incentives to increase the marginal reward for conducting these preventive activities among patients with serious mental illness could have further increased welfare.

Interventions to Prevent Potentially Avoidable Hospitalizations: A Mixed Methods Systematic Review

Background

The demand for healthcare is increasing due to an aging population, more people living with chronic diseases and medical comorbidities. To manage this demand, political institutions call for action to reduce the potentially avoidable hospitalizations. Quantitative and qualitative aspects should be considered to understand how and why interventions work, and for whom. The aim of this mixed methods systematic review was to identify and synthesize evidence on interventions targeting avoidable hospitalizations from the perspectives of the citizens and the healthcare professionals to improve the preventive healthcare services.

Methods and Results

A mixed methods systematic review was conducted following the JBI methodology using a convergent integrated approach to synthesis. The review protocol was registered in PROSPERO, reg. no. CRD42020134652. A systematic search was undertaken in six databases. In total, 45 articles matched the eligibility criteria, and 25 of these (five qualitative studies and 20 quantitative studies) were found to be of acceptable methodological quality. From the 25 articles, 99 meaning units were extracted. The combined evidence revealed four categories, which were synthesized into two integrated findings: (1) Addressing individual needs through care continuity and coordination prevent avoidable hospitalizations and (2) Recognizing preventive care as an integrated part of the healthcare work to prevent avoidable hospitalizations.

Conclusions

The syntheses highlight the importance of addressing individual needs through continuous and coordinated care practices to prevent avoidable hospitalizations. Engaging healthcare professionals in preventive care work and considering implications for patient safety may be given higher priority. Healthcare administers and policy-makers could support the delivery of preventive care through targeted educational material aimed at healthcare professionals and simple web-based IT platforms for information-sharing across healthcare settings. The findings are an important resource in the development and implementation of interventions to prevent avoidable hospitalizations, and may serve to improve patient safety and quality in preventive healthcare services.

Health professionals’ views of the first national GP payment scheme for structured type 2 diabetes care in Ireland: a qualitative study

Background: Payment schemes are widely used to improve chronic disease management in general practice. Although stakeholder views of such schemes could provide valuable learning regarding aspects that work and those which are more difficult to implement, there is a paucity of such data. We explored health professionals’ views of the implementation of the first national general practice payment scheme for type 2 diabetes (T2DM) care in Ireland, the ‘cycle of care’. Methods: Qualitative data were drawn from a multiple case study evaluating the implementation of a National Clinical Programme for Diabetes, collected from April 2016 to June 2017. Interview and focus group transcripts from participants involved in providing diabetes management in general practice and who referenced the cycle of care were eligible for inclusion in the current analysis. Data were analysed using reflective thematic analysis. Results: We analysed data from 28 participants comprising general practitioners (GPs) (n=8), practice nurses (n=9) and diabetes nurse specialists (DNS) (n=11). Participants perceived the cycle of care as “not adequate, but…a good start” to improve T2DM care in general practice in Ireland. Perceived benefits were greater financial viability for T2DM management in general practice, fostering a more proactive approach to T2DM care, delivery of T2DM care closer to patients’ homes, and increased use of other community diabetes services e.g., DNS and podiatry. Participants identified the limited resource for practice nurse time, inflexibility to provide care based on patient need and issues with data submission as drawbacks of the cycle of care. Conclusions: The cycle of care was viewed as a positive first step to increase and improve T2DM care delivered in general practice in Ireland. The implementation issues identified in this study should be considered in the design of future payment schemes targeting chronic disease management in general practice.

The Linkages Between Reimbursement and Prevention: A Mixed-Methods Approach

Background: The benefits of prevention are widely recognized; ranging from avoiding disease onset to substantially reducing disease burden, which is especially relevant considering the increasing prevalence of chronic diseases. However, its delivery has encountered numerous obstacles in healthcare. While healthcare professionals play an important role in stimulating prevention, their behaviors can be influenced by incentives related to reimbursement schemes.

Purpose: The purpose of this research is to obtain a detailed description and explanation of how reimbursement schemes specifically impact primary, secondary, tertiary, and quaternary prevention.

Methods: Our study takes a mixed-methods approach. Based on a rapid review of the literature, we include and assess 27 studies. Moreover, we conducted semi-structured interviews with eight Dutch healthcare professionals and two representatives of insurance companies, to obtain a deeper understanding of healthcare professionals' behaviors in response to incentives.

Results: Nor fee-for-service (FFS) nor salary can be unambiguously linked to higher or lower provision of preventive services. However, results suggest that FFS's widely reported incentive to increase production might work in favor of preventive services such as immunizations but provide less incentives for chronic disease management. Salary's incentive toward prevention will be (partially) determined by provider-organization's characteristics and reimbursement. Pay-for-performance (P4P) is not always necessarily translated into better health outcomes, effective prevention, or adequate chronic disease management. P4P is considered disruptive by professionals and our results expose how it can lead professionals to resort to (over)medicalization in order to achieve targets. Relatively new forms of reimbursement such as population-based payment may incentivize professionals to adapt the delivery of care to facilitate the delivery of some forms of prevention.

Conclusion: There is not one reimbursement scheme that will stimulate all levels of prevention. Certain types of reimbursement work well for certain types of preventive care services. A volume incentive could be beneficial for prevention activities that are easy to specify. Population-based capitation can help promote preventive activities that require efforts that are not incentivized under other reimbursements, for instance activities that are not easily specified, such as providing education on lifestyle factors related to a patient's (chronic) disease.

Chronic care model in the diabetes pay-for-performance program in Taiwan: Benefits, challenges and future directions

In this review, we discuss the chronic care model (CCM) in relation to the diabetes pay-for-performance (P4P) program in Taiwan. We first introduce the 6 components of the CCM and provide a detailed description of each of the activities in the P4P program implemented in Taiwan, mapping them onto the 6 components of the CCM. For each CCM component, the following three topics are described: the definition of the CCM component, the general activities implemented related to this component, and practical and empirical practices based on hospital or local government cases. We then conclude by describing the possible successful features of this P4P program and its challenges and future directions. We conclude that the successful characteristics of this P4P program in Taiwan include its focus on extrinsic and intrinsic incentives (i.e., shared care network), physician-led P4P and the implementation of activities based on the CCM components. However, due to the low rate of P4P program coverage, approximately 50% of patients with diabetes cannot enjoy the benefits of CCM-related activities or receive necessary examinations. In addition, most of these CCM-related activities are not allotted an adequate amount of incentives, and these activities are mainly implemented in hospitals, which compared with primary care providers, are unable to execute these activities flexibly. All of these issues, as well as insufficient implementation of the e-CCM model, could hinder the advanced improvement of diabetes care in Taiwan.

Payment methods for healthcare providers working in outpatient healthcare settings

BACKGROUND

Changes to the method of payment for healthcare providers, including pay-for-performance schemes, are increasingly being used by governments, health insurers, and employers to help align financial incentives with health system goals. In this review we focused on changes to the method and level of payment for all types of healthcare providers in outpatient healthcare settings. Outpatient healthcare settings, broadly defined as 'out of hospital' care including primary care, are important for health systems in reducing the use of more expensive hospital services.

OBJECTIVES

To assess the impact of different payment methods for healthcare providers working in outpatient healthcare settings on the quantity and quality of health service provision, patient outcomes, healthcare provider outcomes, cost of service provision, and adverse effects.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase (searched 5 March 2019), and several other databases. In addition, we searched clinical trials platforms, grey literature, screened reference lists of included studies, did a cited reference search for included studies, and contacted study authors to identify additional studies. We screened records from an updated search in August 2020, with any potentially relevant studies categorised as awaiting classification.

SELECTION CRITERIA

Randomised trials, non-randomised trials, controlled before-after studies, interrupted time series, and repeated measures studies that compared different payment methods for healthcare providers working in outpatient care settings.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. We conducted a structured synthesis. We first categorised the payment methods comparisons and outcomes, and then described the effects of different types of payment methods on different outcome categories. Where feasible, we used meta-analysis to synthesise the effects of payment interventions under the same category. Where it was not possible to perform meta-analysis, we have reported means/medians and full ranges of the available point estimates. We have reported the risk ratio (RR) for dichotomous outcomes and the relative difference (as per cent change or mean difference (MD)) for continuous outcomes.

MAIN RESULTS

We included 27 studies in the review: 12 randomised trials, 13 controlled before-and-after studies, one interrupted time series, and one repeated measure study. Most healthcare providers were primary care physicians. Most of the payment methods were implemented by health insurance schemes in high-income countries, with only one study from a low- or middle-income country. The included studies were categorised into four groups based on comparisons of different payment methods. (1) Pay for performance (P4P) plus existing payment methods compared with existing payment methods for healthcare providers working in outpatient healthcare settings P4P incentives probably improve child immunisation status (RR 1.27, 95% confidence interval (CI) 1.19 to 1.36; 3760 patients; moderate-certainty evidence) and may slightly increase the number of patients who are asked more detailed questions on their disease by their pharmacist (MD 1.24, 95% CI 0.93 to 1.54; 454 patients; low-certainty evidence). P4P may slightly improve primary care physicians' prescribing of guideline-recommended antihypertensive medicines compared with an existing payment method (RR 1.07, 95% CI 1.02 to 1.12; 362 patients; low-certainty evidence). We are uncertain about the effects of extra P4P incentives on mean blood pressure reduction for patients and costs for providing services compared with an existing payment method (very low-certainty evidence). Outcomes related to workload or other health professional outcomes were not reported in the included studies. One randomised trial found that compared to the control group, the performance of incentivised professionals was not sustained after the P4P intervention had ended. (2) Fee for service (FFS) compared with existing payment methods for healthcare providers working in outpatient healthcare settings We are uncertain about the effect of FFS on the quantity of health services delivered (outpatient visits and hospitalisations), patient health outcomes, and total drugs cost compared to an existing payment method due to very low-certainty evidence. The quality of service provision and health professional outcomes were not reported in the included studies. One randomised trial reported that physicians paid via FFS may see more well patients than salaried physicians (low-certainty evidence), possibly implying that more unnecessary services were delivered through FFS. (3) FFS mixed with existing payment methods compared with existing payment methods for healthcare providers working in outpatient healthcare settings FFS mixed payment method may increase the quantity of health services provided compared with an existing payment method (RR 1.37, 95% CI 1.07 to 1.76; low-certainty evidence). We are uncertain about the effect of FFS mixed payment on quality of services provided, patient health outcomes, and health professional outcomes compared with an existing payment method due to very low-certainty evidence. Cost outcomes and adverse effects were not reported in the included studies. (4) Enhanced FFS compared with FFS for healthcare providers working in outpatient healthcare settings Enhanced FFS (higher FFS payment) probably increases child immunisation rates (RR 1.25, 95% CI 1.06 to 1.48; moderate-certainty evidence). We are uncertain whether higher FFS payment results in more primary care visits and about the effect of enhanced FFS on the net expenditure per year on covered children with regular FFS (very low-certainty evidence). Quality of service provision, patient outcomes, health professional outcomes, and adverse effects were not reported in the included studies.

AUTHORS' CONCLUSIONS

For healthcare providers working in outpatient healthcare settings, P4P or an increase in FFS payment level probably increases the quantity of health service provision (moderate-certainty evidence), and P4P may slightly improve the quality of service provision for targeted conditions (low-certainty evidence). The effects of changes in payment methods on health outcomes is uncertain due to very low-certainty evidence. Information to explore the influence of specific payment method design features, such as the size of incentives and type of performance measures, was insufficient. Furthermore, due to limited and very low-certainty evidence, it is uncertain if changing payment models without including additional funding for professionals would have similar effects. There is a need for further well-conducted research on payment methods for healthcare providers working in outpatient healthcare settings in low- and middle-income countries; more studies comparing the impacts of different designs of the same payment method; and studies that consider the unintended consequences of payment interventions.

The evidence gap on gendered impacts of performance-based financing among family physicians for chronic disease care: a systematic review reanalysis in contexts of single-payer universal coverage

BACKGROUND

Although pay-for-performance (P4P) among primary care physicians for enhanced chronic disease management is increasingly common, the evidence base is fragmented in terms of socially equitable impacts in achieving the quadruple aim for healthcare improvement: better population health, reduced healthcare costs, and enhanced patient and provider experiences. This study aimed to assess the literature from a systematic review on how P4P for diabetes services impacts on gender equity in patient outcomes and the physician workforce.

METHODS

A gender-based analysis was performed of studies retrieved through a systematic search of 10 abstract and citation databases plus grey literature sources for P4P impact assessments in multiple languages over the period January 2000 to April 2018, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The study was restricted to single-payer national health systems to minimize the risk of physicians sorting out of health organizations with a strong performance pay component. Two reviewers scored and synthesized the integration of sex and gender in assessing patient- and provider-oriented outcomes as well as the quality of the evidence.

FINDINGS

Of the 2218 identified records, 39 studies covering eight P4P interventions in seven countries were included for analysis. Most (79%) of the studies reported having considered sex/gender in the design, but only 28% presented sex-disaggregated patient data in the results of the P4P assessment models, and none (0%) assessed the interaction of patients' sex with the policy intervention. Few (15%) of the studies controlled for the provider's sex, and none (0%) discussed impacts of P4P on the work life of providers from a gender perspective (e.g., pay equity).

CONCLUSIONS

There is a dearth of evidence on gender-based outcomes of publicly funded incentivizing physician payment schemes for chronic disease care. As the popularity of P4P to achieve health system goals continues to grow, so does the risk of unintended consequences. There is a critical need for research integrating gender concerns to help inform performance-based health workforce financing policy options in the era of the Sustainable Development Goals.

Effects of Point-Of-Care Testing in General Practice for Type 2 Diabetes Patients on Ambulatory Visits and Hospitalizations

Point-of-care testing (POCT) of HbA1c means instant test results and more coherent counseling that is expected to improve diabetes management and affect ambulatory visits and hospitalizations. From late 2008, POCT has been implemented and adopted by a segment of the general practices in the capital region of Denmark. The aim of this study is to assess whether the introduction of POCT of HbA1c in general practice (GP) has affected patient outcomes for T2 diabetes patients in terms of hospital activity. We apply difference-in-differences models at the GP clinic level to assess the casual effects of POCT on the following hospital outcomes: (1) admissions for diabetes, (2) admissions for ambulatory care sensitive diabetes conditions (ACSCs), (3) ambulatory visits for diabetes. The use of POCT is remunerated by a fee, and registration of this fee is used to measure the GP’s use of POCT. The control group includes clinics from the same region that did not use POCT. The sensitivity of our results is assessed by an event study approach and a range of robustness tests. The panel data set includes 553 GP clinics and approximately 30,000 diabetes patients from the capital region of Denmark, observed in the years 2004–2012. We find that voluntary adoption of POCT of HbA1c in GP has no effect on hospital admissions and diabetes-related hospital ambulatory visits. Event study analysis and different treatment definitions confirm the robustness of these results. If implementation of POCT of HbA1c improves other parts of diabetes management as indicated in the literature, it seems worthwhile to implement POCT of HbA1c in the capital region of Denmark. However, doubts around the quality of POCT of HbA1c testing and a desire to capture data at central labs may prevent implementation of more value based HbA1c testing.

Adherence to medical follow-up recommendations reduces hospital admissions: Evidence from diabetic patients in France

The aim of this study was to document the extent to which diabetic patients who adhered to required medical follow-ups in France experienced reduced hospital admissions over time. The main assumption was that enhanced monitoring and follow-up of diabetic patients in the primary care setting could be a substitute for hospital use. Using longitudinal claim data of diabetic patients between 2010 and 2015 from MGEN, a leading mutuelle insurance company in France, we estimated a dynamic logit model with lagged measures of the quality of adherence to eight medical follow-up recommendations. This model allowed us to disentangle follow-up care in hospitals from other forms of inpatient care that could occur simultaneously. We found that a higher adherence to medical guidance is associated with a lower probability of hospitalization and that the take-up of each of the eight recommendations may help reduce the rates of hospital admission. The reasons for the variation in patient adherence and implications for health policy are discussed.

Effects of pay-for-performance for primary care physicians on diabetes outcomes in single-payer health systems: a systematic review

BACKGROUND

Although pay-for-performance (P4P) for diabetes care is increasingly common, evidence of its effectiveness in improving population health and health system sustainability is deficient. This information gap is attributable in part to the heterogeneity of healthcare financing, covered medical conditions, care settings, and provider remuneration arrangements within and across countries. We systematically reviewed the literature concentrating on whether P4P for physicians in primary and community care leads to better diabetes outcomes in single-payer national health insurance systems.

METHODS

Studies were identified by searching ten databases (01/2000-04/2018) and scanning the reference lists of review articles and other global health literature. We included primary studies evaluating the effects of introducing P4P for diabetes care among primary care physicians in countries of universal health coverage. Outcomes of interest included patient morbidity, avoidable hospitalization, premature death, and healthcare costs.

RESULTS

We identified 2218 reports; after exclusions, 10 articles covering 8 P4P interventions in 7 countries were eligible for analysis. Five studies, capturing records from 717,166 patients with diabetes, were graded as high-quality evaluations of P4P on health outcomes. Based on three quality studies, P4P can result in reduced risk of mortality over the longer term-when linked to performance metrics. However, studies from other jurisdictions, where P4P was not linked to specific patient-oriented objectives, yielded little or mixed evidence of positive health impacts.

CONCLUSION

Evidence of the effectiveness of P4P depends on whether physicians' incentive payments are explicitly tied to performance metrics. However, the most appropriate indicators for performance monitoring remain in question. More research with rigorous evaluation in different settings is needed.

Cost-effectiveness of introducing licensed GP practices to manage diabetes patients in Hungary

AIM

To investigate the cost-effectiveness of the endowment of the same authority and responsibility in diabetes management to licensed GPs as licensed outpatient specialists in Hungary.

METHODS

The Syreon Diabetes Control Model (SDM) was used to evaluate life expectancy, quality-adjusted life expectancy (QALY) and direct medical costs over patient lifetimes. Cohort characteristics were derived from national database, clinical history data of 476,211 persons with diabetes were used, treatment effects and costs were derived from literature, national databases and expert opinions.

RESULTS

The purchase of one additional quality adjusted life year with the use of licensed general practitioners was EUR 51,420 compared to making the service available only through universal GPs. The purchase of one additional quality adjusted life year through the service of licensed GPs is EUR 459,950 compared to outpatient care provision.

CONCLUSIONS

The management of diabetes care with licensed GPs has the potential to improve patients health gains compared to the current patterns of care in Hungary in a cost-effective way if licensed GPs are reimbursed below the average current cost of outpatient diabetes services. Increase of the capitation for diabetic patients would be a practical way to reimburse the GP's additional service.

Disease management in diabetes care: When involving GPs improves patient compliance and health outcomes

Although the study of the association between interventions in primary care and health outcomes continues to produce mixed findings, programs designed to promote the greater compliance of General Practitioners and their diabetic patients with guidelines have been increasingly introduced worldwide, in an attempt to achieve better quality diabetes care through the enhanced standardisation of patient supervision. In this study, we use clinical data from the Diabetes Register of one large Local Health Authority (LHAs) in Italy's Emilia-Romagna Region for the period 2012-2015. Firstly, we investigate whether GPs' participation in the local Diabetes Management Program (DMP) leads to improved patient compliance with regional guidelines. Secondly, we test whether the monitoring activities prescribed for diabetics by the Regional diabetes guidelines have a positive impact on patients' health outcomes and increase appropriateness in health care utilization. Our results show that such a Program, which aims to increase GPs' involvement and cooperation in following the Regional guidelines, achieves its goal of improved patient compliance with the prescribed actions. In turn, through the implementation of the DMP and the greater involvement of physicians, Regional policies have succeeded in promoting better health outcomes and improved appropriateness of health care utilization.

Blended capitation and incentives: Fee codes inside and outside the capitated basket

Blended capitation physician payment models incorporating fee-for-service (FFS), pay-for-performance and/or other payment elements seek to avoid the extremes of both FFS and capitation. However, evidence is limited regarding physicians' responses to blended models, and potential shifts in service provision across payment categories within the practice. We examine the switch from FFS to a blended capitation-FFS model for primary care physicians in group practice. The empirical analysis shows patients experiencing 9-14% reductions in capitated services and simultaneous increases of 10-22% in FFS services from their rostering physicians. Unusually, our data permit changes among non-rostering physicians to be observed. Other physicians within the rostering group reduce the provision of capitated fee codes, with no net change in FFS services. All other physicians in the jurisdiction reduce both capitated and FFS services, which is consistent with patients concentrating their primary care with one provider as a result of capitation.

Can external interventions crowd in intrinsic motivation? A cluster randomised field experiment on mandatory accreditation of general practice in Denmark

Motivation crowding studies have demonstrated that external interventions can harm effort and performance through crowding out of intrinsic motivation, when interventions are perceived as lack of trust. However, motivation crowding theory also presents a much less investigated crowding in effect, which occurs when external interventions increase intrinsic motivation. This study empirically tests the motivational effect of a specific external intervention and its associations with the perception of the intervention. We draw on a cluster randomised stepwise introduction of a mandatory accreditation system in general practice in Denmark combined with baseline and follow-up questionnaires of 1146 GPs. Based on a series of mixed effects multilevel models, we find no evidence of motivation crowding out among surveyed GPs, although most GPs perceived accreditation as a tool for external control prior to its implementation. Rather, our results indicate that being accredited crowds in intrinsic motivation. This is especially the case when GPs perceive accreditation as an instrument for quality improvement. External interventions can therefore, at least in some cases, foster intrinsic motivation of health care professionals.

The effect of a hepatitis pay-for-performance program on outcomes of patients undergoing antiviral therapy

Background

To examine the effect of a participatory pay-for-performance (P4P) program in Taiwan on health outcomes for patients with severe hepatitis B or C.

Methods

This study adopted 4-year panel data from the databases of the National Health Insurance Administration (NHIA) in Taiwan. Using the caliper matching method to match patients in the P4P (experimental) group with those in the potential comparison group on a one-to-one basis for the year 2010, we tracked patients up to the year 2013 and employed Cox proportional-hazards regression models to evaluate the effect on patient outcomes.

Results

The P4P group did not have a lower risk (HR = 0.44, P = 0.05) of hospital admission for severe hepatitis patients (i.e. need antiviral therapy). The risk of developing liver cirrhosis was also lower, but the reduction was not statistically significant (HR = 0.92, P = 0.77).

Conclusions

This study found that participatory-type P4P has not resulted in reduced hospital admission of hepatitis B or C patients who need antiviral therapy. The means by which the participatory P4P program could strengthen patient-centered care to achieve better patient health outcomes is discussed in detail.

Quality of diabetes follow-up care and hospital admissions

Diabetes may lead to severe complications. For this reason, disease prevention and improvement of medical follow-up represent major public health issues. The aim of this study was to measure the impact of adherence to French follow-up guidelines on hospitalization of people with diabetes. We used insurance claims data from the years 2010 to 2013 collected for 52,027 people aged over 18, affiliated to a French social security provider and treated for diabetes. We estimated panel data models to explore the association between adherence to guidelines and different measures of hospitalization, controlling for socioeconomic characteristics, diabetes treatment and density of medical supply. The results show that adherence to four guidelines was associated with a significant decrease in hospital admissions, up to approximatively 30% for patients monitored for a complete lipid profile or microalbuminuria during the year. In addition, our analyses confirmed the strong protective effect of income and a significant positive correlation with good supply of hospital care. In conclusion, good adherence to French diabetes guidelines seems to be in line with the prevention of health events, notably complications, that could necessitate hospitalization.

Socio-economic status and physicians' treatment decisions

This paper studies the relationship between patients' socio-economic status and general practitioners' (GPs') service provision by exploiting administrative patient-level data with information on consultation length, medical tests, and fee payments for each visit in Norway over a 5-year period (2008-2012). To reduce patient heterogeneity, we limit the sample to a given condition, diabetes type II, that is treated almost exclusively in primary care. We estimate GP fixed-effect models and control for a wide set of patient characteristics. Our results show that, for each visit, patients with low education get shorter consultations but more medical tests, patients with low income get less of both, and patients with low education/income get less services in monetary terms. We also find that, during a year, patients with low education/income visit the GP more often and receive more services in monetary terms. Thus, GPs treat patients differently according to their socio-economic status, but we find no support for a social gradient.

Variation in Point-of-Care Testing of HbA1c in Diabetes Care in General Practice

Background: Point-of-care testing (POCT) of HbA1c may result in improved diabetic control, better patient outcomes, and enhanced clinical efficiency with fewer patient visits and subsequent reductions in costs. In 2008, the Danish regulators created a framework agreement regarding a new fee-for-service fee for the remuneration of POCT of HbA1c in general practice. According to secondary research, only the Capital Region of Denmark has allowed GPs to use this new incentive for POCT. The aim of this study is to use patient data to characterize patients with diabetes who have received POCT of HbA1c and analyze the variation in the use of POCT of HbA1c among patients with diabetes in Danish general practice. Methods: We use register data from the Danish Drug Register, the Danish Health Service Register and the National Patient Register from the year 2011 to define a population of 44,981 patients with diabetes (type 1 and type 2 but not patients with gestational diabetes) from the Capital Region. The POCT fee is used to measure the amount of POCT of HbA1c among patients with diabetes. Next, we apply descriptive statistics and multilevel logistic regression to analyze variation in the prevalence of POCT at the patient and clinic level. We include patient characteristics such as gender, age, socioeconomic markers, health care utilization, case mix markers, and municipality classifications. Results: The proportion of patients who received POCT was 14.1% and the proportion of clinics which were “POCT clinics” was 26.9%. There were variations in the use of POCT across clinics and patients. A part of the described variation can be explained by patient characteristics. Male gender, age differences (older age), short education, and other ethnicity imply significantly higher odds for POCT. High patient costs in general practice and other parts of primary care also imply higher odds for POCT. In contrast, high patient costs for drugs and/or morbidity in terms of the Charlson Comorbidity index mean lower odds for POCT. The frequency of patients with diabetes per 1000 patients was larger in POCT clinics than Non-POCT clinics. A total of 22.5% of the unexplained variability was related to GP clinics. Conclusions: This study demonstrates variation in the use of POCT which can be explained by patient characteristics such as demographic, socioeconomic, and case mix markers. However, it appears relevant to reassess the system for POCT. Further studies are warranted in order to assess the impacts of POCT of HbA1c on health care outcomes.

Spatial effects in hospital expenditures: A district level analysis

We use spatial econometric methods to analyse spillovers in hospital expenditures across Health Districts of the Emilia-Romagna Region (Italy). We estimate spatial models that allow for global spillovers and distinguish between the expenditures associated with potentially inappropriate hospitalizations and those associated with complex medical procedures. We also investigate the relative contribution of geographical and institutional proximity in explaining spatial dependence, by explicitly modelling different connectivity structures and exploiting them to build alternative spatial weight matrices. We find that interactions largely differ between types of expenditures, with positive spatial effects for potentially inappropriate admissions, the effect being generally not significant for high-complexity expenditure. Relying on the estimated direct and indirect effects, we also test for the presence of spatial spillovers across districts. Finally, the paper draws policy implications for the public health planner.

Does the extension of primary care practice opening hours reduce the use of emergency services?

Overcrowding in emergency departments generates potential inefficiencies. Using regional administrative data, we investigate the impact that an increase in the accessibility of primary care has on emergency visits in Italy. We consider two measures of avoidable emergency visits recorded at list level for each General Practitioner. We test whether extending practices' opening hours to up to 12 hours/day reduces the inappropriate utilization of emergency services. Since subscribing to the extension program is voluntary, we account for the potential endogeneity of participation in a count model for emergency admissions in two ways: first, we use a two-stage residual inclusion approach. Then we exploit panel methods on data covering a three-year period, thus accounting directly for individual heterogeneity. Our results show that increasing primary care accessibility acts as a restraint on the inappropriate use of emergency departments. The estimated effect is in the range of a 10-15% reduction in inappropriate admissions.

Exploring the determinants of endocrinologist visits by patients with diabetes

BACKGROUND

Diabetes is today a major public health concern in terms of its financial and social burden. Previous studies have revealed that specialist care for patients with diabetes leads to more positive outcomes than care by general practitioners (GPs) alone. The aim of this study was to estimate the determinants of endocrinologist consultation by patients with diabetes.

METHODS

We used a two-part model to explore both the decision to consult and the frequency of consultations. We used claim data collected for 65,633 affiliates of a French social security provider. Patients were aged over 18 and treated for diabetes (types I and II). We controlled for patients' socioeconomic characteristics, type of diabetes treatment, medical care, and health status. We also controlled for variables, such as the cost of a visit, the distance to the nearest endocrinologist's office, the density of medical practitioners and the prevalence of diabetes in the area.

RESULTS

The results show that the parameters associated with the decision to consult an endocrinologist were considerably different from factors associated with the frequency of consultations. A marked positive effect of income on the decision to consult was found, whereas travel time to the office had a negative impact on both the decision to consult and the frequency of consultations. Increasing treatment complexity is associated with a higher probability of consulting an endocrinologist. We found evidence of a significant substitution effect between GPs and endocrinologists. Finally, consultation price is a barrier to seeing an endocrinologist.

CONCLUSION

Given that financial barriers were identified in the relatively wealthy population analysed here, it is likely that this may be even more of an obstacle in the general population.

Participating physician preferences regarding a pay-for-performance incentive design: a discrete choice experiment

OBJECTIVE

To determine whether the magnitude of incentives or other design attributes should be prioritized and the most important attributes, according to physicians, of the diabetes P4P (pay-for-performance) program design.

DESIGN

We implemented a discrete choice experiment (DCE) to elicit the P4P incentive design-related preferences of physicians.

PARTICIPANTS

All of the physicians (n = 248) who participated in the diabetes P4P program located in the supervisory area of the northern regional branch of the Bureau of National Health Insurance in 2009 were included. The response rate was ∼ 60%.

RESULTS

Our research found that the bonus type of incentive was the most important attribute, followed by the incentive structure and the investment magnitude.

CONCLUSIONS

Physicians may feel that good P4P designs are more important than the magnitude of the investment by the insurer. The two most important P4P designs include providing the bonus type of incentive and using pay-for-excellence plus pay-for-improvement.
