Quality of Disease Management and Risk of Mortality in English Primary Care Practices

Abstract

Objective. To investigate whether better management of chronic conditions by family practices reduces mortality risk. Data. Two random samples of 5 million patients registered with over 8,000 English family practices followed up for 4 years (2004/5-2007/8). Measures of the quality of disease management for 10 conditions were constructed for each family practice for each year. The outcome measure was an indicator taking the value 1 if the patient died during a specified year, 0 otherwise. Study Design. Cross-section and multilevel panel data multiple logistic regressions were estimated. Covariates included age, gender, morbidity, hospitalizations, attributed socio-economic characteristics, and local health care supply measures. Principal Findings. Although a composite measure of the quality of disease management for all 10 conditions was significantly associated with lower mortality, only the quality of stroke care was significant when all 10 quality measures were entered in the regression. Conclusions. The panel data results suggest that a 1 percent improvement in the quality of stroke care could reduce the annual number of deaths in England by 782 [95 percent CI: 423, 1140]. A longer study period may be necessary to detect any mortality impact of better management of other conditions.

Primary care consultation rates among people with and without severe mental illness: a UK cohort study using the Clinical Practice Research Datalink

“…However, our findings suggest that people with SMI generally have the opportunity to be in receipt of the checks required by QOF, given the observed face-to-face consultation rates, although the effectiveness of these checks in improving patient health is still being debated. 40–43 In line with the national well-being and recovery agenda, consultation rates may continue to increase further as Community Mental Health Teams are encouraged to discharge all but the most severe cases back to primary care. Conversely, the removal of cardiometabolic QOF indicators (requiring annual recording of weight, blood cholesterol and glucose) in 2014 might curb such an increase.…”

Location, quality and choice of hospital: Evidence from England 2002–2013

“…An electronic booking system (Choose and Book) was introduced in 2005/6 to allow direct booking of referrals from general practices. By 2012/13, 50% of all referrals were made via the system ( Dusheiko and Gravelle, 2015 ). Since 2007 the NHS Choices website has provided public information on the location, services and quality of providers.…”

Health Equity Indicators for the English NHS: a longitudinal whole-population study at the small-area level

“…12 International studies have demonstrated that improving the process quality of primary care is associated with reduced emergency admissions, improved patient outcomes and reduced costs to the health-care system. [78][79][80] Moreover, small improvements in primary care process quality can have significant effects on population health at low cost. 81 Improving the quality of primary care has been incentivised in several countries, primarily using financial incentives.…”

“…Furthermore, there is uncertainty about how long it takes for improvements in health-care delivery to feed through into reductions in preventable hospitalisation and amenable mortality. It is reasonable to expect some short-term impact within a year or two, 80 although the length of lag is likely to vary by disease and type of intervention; for example, reductions in mortality because of improved management of heart disease and diabetes may be more rapid than reductions as a result of earlier diagnosis and referral for suspected cancer.…”
