The effects of pay for performance on disparities in stroke, hypertension, and coronary heart disease management: interrupted time series study.

ABSTRACT:

Background

The Quality and Outcomes Framework (QOF), a major pay-for-performance programme, was introduced into United Kingdom primary care in April 2004. The impact of this programme on disparities in health care remains unclear. This study examines the following questions: has this pay for performance programme improved the quality of care for coronary heart disease, stroke and hypertension in white, black and south Asian patients? Has this programme reduced disparities in the quality of care between these ethnic groups? Did general practices with different baseline performance respond differently to this programme?

Methodology/principal findings

Retrospective cohort study of patients registered with family practices in Wandsworth, London during 2007. Segmented regression analysis of interrupted time series was used to take into account the previous time trend. Primary outcome measures were mean systolic and diastolic blood pressure, and cholesterol levels. Our findings suggest that the implementation of QOF resulted in significant short term improvements in blood pressure control. The magnitude of benefit varied between ethnic groups with a statistically significant short term reduction in systolic BP in white and black but not in south Asian patients with hypertension. Disparities in risk factor control were attenuated only on few measures and largely remained intact at the end of the study period.

Conclusions/significance

Pay for performance programmes such as the QOF in the UK should set challenging but achievable targets. Specific targets aimed at reducing ethnic disparities in health care may also be needed.

Project description:ObjectiveTo assess the impact of a pay for performance incentive on quality of care and outcomes among UK patients with hypertension in primary care.DesignInterrupted time series.SettingThe Health Improvement Network (THIN) database, United Kingdom.Participants470 725 patients with hypertension diagnosed between January 2000 and August 2007.InterventionThe UK pay for performance incentive (the Quality and Outcomes Framework), which was implemented in April 2004 and included specific targets for general practitioners to show high quality care for patients with hypertension (and other diseases).Main outcome measuresCentiles of systolic and diastolic blood pressures over time, rates of blood pressure monitoring, blood pressure control, and treatment intensity at monthly intervals for baseline (48 months) and 36 months after the implementation of pay for performance. Cumulative incidence of major hypertension related outcomes and all cause mortality for subgroups of newly treated (treatment started six months before pay for performance) and treatment experienced (started treatment in year before January 2001) patients to examine different stages of illness.ResultsAfter accounting for secular trends, no changes in blood pressure monitoring (level change 0.85, 95% confidence interval -3.04 to 4.74, P=0.669 and trend change -0.01, -0.24 to 0.21, P=0.615), control (-1.19, -2.06 to 1.09, P=0.109 and -0.01, -0.06 to 0.03, P=0.569), or treatment intensity (0.67, -1.27 to 2.81, P=0.412 and 0.02, -0.23 to 0.19, P=0.706) were attributable to pay for performance. Pay for performance had no effect on the cumulative incidence of stroke, myocardial infarction, renal failure, heart failure, or all cause mortality in both treatment experienced and newly treated subgroups.ConclusionsGood quality of care for hypertension was stable or improving before pay for performance was introduced. Pay for performance had no discernible effects on processes of care or on hypertension related clinical outcomes. Generous financial incentives, as designed in the UK pay for performance policy, may not be sufficient to improve quality of care and outcomes for hypertension and other common chronic conditions.

Project description:ObjectiveTo evaluate the effects of Quality and Outcomes Framework (QOF) incentivised case finding for depression on diagnosis and treatment in targeted and non-targeted long-term conditions.DesignInterrupted time series analysis.SettingGeneral practices in Leeds, UK.Participants65 (58%) of 112 general practices shared data on 37,229 patients with diabetes and coronary heart disease targeted by case finding incentives, and 101,008 patients with four other long-term conditions not targeted (hypertension, epilepsy, chronic obstructive pulmonary disease and asthma).InterventionIncentivised case finding for depression using two standard screening questions.Main outcome measuresClinical codes indicating new depression-related diagnoses and new prescriptions of antidepressants. We extracted routinely recorded data from February 2002 through April 2012. The number of new diagnoses and prescriptions for those on registers was modelled with a binomial regression, which provided the strength of associations between time periods and their rates.ResultsNew diagnoses of depression increased from 21 to 94/100,000 per month in targeted patients between the periods 2002-2004 and 2007-2011 (OR 2.09; 1.92 to 2.27). The rate increased from 27 to 77/100,000 per month in non-targeted patients (OR 1.53; 1.46 to 1.62). The slopes in prescribing for both groups flattened to zero immediately after QOF was introduced but before incentivised case finding (p<0.01 for both). Antidepressant prescribing in targeted patients returned to the pre-QOF secular upward trend (Wald test for equivalence of slope, z=0.73, p=0.47); the slope was less steep for non-targeted patients (z=-4.14, p<0.01).ConclusionsIncentivised case finding increased new depression-related diagnoses. The establishment of QOF disrupted rising trends in new prescriptions of antidepressants, which resumed following the introduction of incentivised case finding. Prescribing trends are of concern given that they may include people with mild-to-moderate depression unlikely to respond to such treatment.

Project description:BackgroundDisease Management Programmes (DMPs) aim to improve effectiveness and equity of care but may suffer from selective enrolment. We analysed social disparities in DMP enrolment among elderly patients with coronary heart disease (CHD) in Germany, taking into account contextual effects at municipality and primary care practice levels.MethodsCross-sectional analysis of effects of educational attainment and regional deprivation on physician-reported DMP enrolment in a subsample of a large population-based cohort study in Germany, adjusting for individual-level, practice-level and area-level variables. We calculated OR and their 95% CIs (95% CI) in cross-classified, multilevel logistic regression models.ResultsAmong N=1280 individuals with CHD (37.3% women), DMP enrolment rates were 22.2% (women) and 35% (men). The odds of DMP enrolment were significantly higher for male patients (OR=1.98 (1.50 to 2.62)), even after adjustment for potential confounding by individual-level, practice-level and area-level variables (range: OR=1.60 (1.08 to 2.36) to 2.16 (1.57 to 2.98)). Educational attainment was not significantly associated with DMP enrolment. Compared to patients living in least-deprived municipalities, the adjusted propensity of DMP enrolment was statistically significantly lower for patients living in medium-deprived municipalities (OR=0.41 (0.24 to 0.71)), and it also tended to be lower for patients living in the most-deprived municipalities (OR=0.70 (0.40 to 1.21)). Models controlling for the social situation (instead of health-related behaviour) yielded comparable effect estimates (medium-deprived/most-deprived vs least-deprived areas: OR=0.45 (0.26 to 0.78)/OR=0.68 (0.33 to 1.19)). Controlling for differences in comorbidity attenuated the deprivation effect estimates.ConclusionsWe found evidence for marked gender, but not educational disparities in DMP enrolment among patients with CHD. Small-area deprivation was associated with DMP enrolment, but the effects were partly explained by differences in comorbidity. Future studies on DMPs should consider contextual effects when analysing programme effectiveness or impacts on equity and efficiency.

Project description:BackgroundLong-acting reversible contraception (LARC) is among the most effective contraceptive methods, but uptake remains low even in high-income settings. In 2009/2010, a target-based pay-for-performance (P4P) scheme in Britain was introduced for primary care physicians (PCPs) to offer advice about LARC methods to a specified proportion of women attending for contraceptive care to improve contraceptive choice. We examined the impact and equity of this scheme on LARC uptake and abortions.Methods and findingsWe examined records of 3,281,667 women aged 13 to 54 years registered with a primary care clinic in Britain (England, Wales, and Scotland) using Clinical Practice Research Datalink (CPRD) from 2004/2005 to 2013/2014. We used interrupted time series (ITS) analysis to examine trends in annual LARC and non-LARC hormonal contraception (NLHC) uptake and abortion rates, stratified by age and deprivation groups, before and after the P4P was introduced in 2009/2010. Between 2004/2005 and 2013/2014, crude LARC uptake rates increased by 32.0% from 29.6 per 1,000 women to 39.0 per 1,000 women, compared with 18.0% decrease in NLHC uptake. LARC uptake among women of all ages increased immediately after the P4P with step change of 5.36 per 1,000 women (all values are per 1,000 women unless stated, 95% CI 5.26-5.45, p < 0.001). Women aged 20 to 24 years had the largest step change (8.40, 8.34-8.47, p < 0.001) and sustained trend increase (3.14, 3.08-3.19, p < 0.001) compared with other age groups. NLHC uptake fell in all women with a step change of -22.8 (-24.5 to -21.2, p < 0.001), largely due to fall in combined hormonal contraception (CHC; -15.0, -15.5 to -14.5, p < 0.001). Abortion rates in all women fell immediately after the P4P with a step change of -2.28 (-2.98 to -1.57, p = 0.002) and sustained decrease in trend of -0.88 (-1.12 to -0.63, p < 0.001). The largest falls occurred in women aged 13 to 19 years (step change -5.04, -7.56 to -2.51, p = 0.011), women aged 20 to 24 years (step change -4.52, -7.48 to -1.57, p = 0.030), and women from the most deprived group (step change -4.40, -6.89 to -1.91, p = 0.018). We estimate that by 2013/2014, the P4P scheme resulted in an additional 4.53 LARC prescriptions per 1,000 women (relative increase of 13.4%) more than would have been expected without the scheme. There was a concurrent absolute reduction of -5.31 abortions per 1,000 women, or -38.3% relative reduction. Despite universal coverage of healthcare, some women might have obtained contraception elsewhere or had abortion procedure that was not recorded on CPRD. Other policies aiming to increase LARC use or reduce unplanned pregnancies around the same time could also explain the findings.ConclusionsIn this study, we found that LARC uptake increased and abortions fell in the period after the P4P scheme in British primary care, with additional impact for young women aged 20-24 years and those from deprived backgrounds.

Project description:Achieving control of hypertension prevents target organ damage at both the micro and macrovascular level and is a highly cost effective means of lowering the risk for heart attack and stroke particularly in people with diabetes. Clinical trials demonstrate that blood pressure control can be achieved in a large proportion of people. Translating this knowledge into widespread practice is the focus of the Hypertension Management Initiative, which began in 2004 with the goal of improving the management of this chronic health condition by primary care providers and patients in the community.This study will test the effect of a systems change on the management of high blood pressure in real world practice in primary care in Ontario, Canada. The systems change intervention involves an interprofessional educational program bringing together physicians, nurses and pharmacists with tools for both providers and patients to facilitate blood pressure management. Each of two waves of subjects were enrolled over a 6 month period with the initial enrollment between waves separated by 9 months. Blood pressure will be measured with the BpTru automated blood pressure device. To determine the effectiveness of the intervention, a before and after analysis within all subjects will compare blood pressure at baseline to annual measurements for the three year study. To assess whether the intervention has an impact on blood pressure control independent of community trends, a betwen group comparison of baseline blood pressures in the delayed wave will be made with the immediate wave during the same time period, so that the immediate wave has experienced the intervention for at least 9 months. The total enrollment goal is 5,000 subjects. The practice locations include 10 Family Health Teams (FHTs) and 1 Community Health Centre (CHC) and approximately 49 primary care physicians, 15 nurse practitioners, 37 registered nurses and over 150 community pharmacists across the 11 communities throughout the province of Ontario. The 11 primary care sites will be divided into immediate and delayed groups based on geography and the use of an electronic versus a traditional chart patient record.Initial consideration was given to randomizing the groups, however, for a number of reasons, this was deemed to not be possible. In order to ensure that the sites in the immediate intervention and delayed intervention groups are not different from each other, the sites will be assigned to the intervention groups manually to ensure a distribution of the variables as evenly as possible. Given that HSFO approached this particular group of health care providers to participate in a program relating to hypertension, this may have heightened their awareness of the issue and affected their management of patients with hypertension. Thus, data will be collected to allow an assessment of previous practice patterns and determine any impact of the Hawthorne Effect.Clinicaltrials.gov NCT00425828.
