Patient and primary care physician characteristics associated with billing incentives for chronic diseases in British Columbia: a retrospective cohort study.

BACKGROUND: Incentive payments for chronic diseases in British Columbia were intended to support primary care physicians in providing more comprehensive care, but research shows that not all physicians bill incentives and not all eligible patients have them billed on their behalf. We investigated patient and physician characteristics associated with billing incentives for chronic diseases in BC. METHODS: We conducted a retrospective cohort analysis using linked administrative health data to examine community-based primary care physicians and patients with eligible chronic conditions in BC during 2010-2013. Descriptive analyses of patients and physicians compared 3 groups: no incentives in any of the 4 years, incentives in all 4 years, and incentives in any of the study years. We used hierarchical logistic regression models to identify the patient- and physician-level characteristics associated with billing incentives. RESULTS: Of 428 770 eligible patients, 142 475 (33.2%) had an incentive billed on their behalf in all 4 years, and 152 686 (35.6%) never did. Of 3936 physicians, 2625 (66.7%) billed at least 1 incentive in each of the 4 years, and 740 (18.8%) billed no incentives during the study period. The strongest predictors of having an incentive billed were the number of physician contacts a patient had (odds ratio [OR] for > 48 contacts 134.77, 95% confidence interval [CI] 112.27-161.78) and whether a physician had a large number of patients in his or her practice for whom incentives were billed (OR 42.38 [95% CI 34.55-52.00] for quartile 4 v. quartile 1). INTERPRETATION: The findings suggest that primary care physicians bill incentives for patients based on whom they see most often rather than using a population health management approach to their practice.

Designation, diligence and drift: understanding laboratory expenditure increases in British Columbia, 1996/97 to 2005/06.

BACKGROUND: Laboratory testing is one of the fastest growing areas of health services spending in Canada. We examine the extent to which increases in laboratory expenditures might be explained by testing that is consistent with guidelines for the management of chronic conditions, by analyzing fee-for-service physician payment data in British Columbia from 1996/97 and 2005/06. METHOD: We used direct standardization to quantify the effect on laboratory expenditures from changes in: fee levels; population growth; population aging; treatment prevalence; expenditure on recommended tests for those conditions; and expenditure on other tests. The chronic conditions selected were those with guidelines containing laboratory recommendations developed by the BC Guidelines and Protocol Advisory Committee: diabetes, hypertension, congestive heart failure, renal failure, liver disease, rheumatoid arthritis, osteoarthritis and dementia. RESULT: Laboratory service expenditures increased by $98 million in 2005/06 compared to 1996/97, or 3.6% per year after controlling for population growth and aging. Testing consistent with guideline-recommended care for chronic conditions explained one-third (1.2% per year) of this growth. Changes in treatment prevalence were just as important, contributing 1.5% per year. Hypertension was the most common condition, but renal failure and dementia showed the largest changes in prevalence over time. Changes in other laboratory expenditure including for those without chronic conditions accounted for the remaining 0.9% growth per year. CONCLUSION: Increases in treatment prevalence were the largest driver of laboratory cost increases between 1996/97 and 2005/06. There are several possible contributors to increasing treatment prevalence, all of which can be expected to continue to put pressure on health care expenditures.

British Columbia hospitals: examination and assessment of payment reform (B-CHeaPR).

BACKGROUND: Accounting for 36% of public spending on health care in Canada, hospitals are a major target for cost reductions through various efficiency initiatives. Some provinces are considering payment reform as a vehicle to achieve this goal. With few exceptions, Canadian provinces have generally relied on global and line-item budgets to contain hospital costs. There is growing interest amongst policy-makers for using activity based funding (ABF) as means of creating financial incentives for hospitals to increase the 'volume' of care, reduce cost, discourage unnecessary activity, and encourage competition. British Columbia (B.C.) is the first province in Canada to implement ABF for partial reimbursement of acute hospitalization. To date, there have been no formal examinations of the effects of ABF policies in Canada. This study proposal addresses two research questions designed to determine whether ABF policies affect health system costs, access and hospital quality. The first question examines the impact of the hospital funding policy change on internal hospital activity based on expenditures and quality. The second question examines the impact of the change on non-hospital care, including readmission rates, amount of home care provided, and physician expenditures. METHODS/DESIGN: A longitudinal study design will be used, incorporating comprehensive population-based datasets of all B.C. residents; hospital, continuing care and physician services datasets will also be used. Data will be linked across sources using anonymized linking variables. Analytic datasets will be created for the period between 2005/2006 and 2012/2013. DISCUSSION: With Canadian hospitals unaccustomed to detailed scrutiny of what services are provided, to whom, and with what results, the move toward ABF is significant. This proposed study will provide evidence on the impacts of ABF, including changes in the type, volume, cost, and quality of services provided. Policy- and decision-makers in B.C. and elsewhere in Canada will be able to use this evidence as a basis for policy adaptations and modifications. The significance of this proposed study derives from the fact that the change in hospital funding policy has the potential to affect health system costs, residents' access to care and care quality.

Using population data to measure outcomes of care: the case of hip and knee replacements.

BACKGROUND: Accumulating evidence points to overall improvements in health-related quality of life after joint replacement for osteoarthritis. Some patients, however, do not appear to benefit from joint replacement. This study investigates health outcomes of patients who underwent hip or knee replacement surgery. METHODS: Linked survey and administrative data were used to compare the health-related quality of life of individuals who underwent surgery (surgical group) with that of their contemporaries who did not (comparison group), adjusting for other determinants of health. Weighted multivariate linear regression analyses were conducted. RESULTS: When the results were adjusted for other covariates known to be associated with health, the surgical group reported lower functional health (post-operative) than did the comparison group. Differences ranged from 6% lower functional health among hip replacement patients diagnosed with osteoarthritis to 21% lower functional health for those with hip fractures. Among surgical patients with osteoarthritis, co-morbid conditions and being underweight were associated with lower post-operative functional health. INTERPRETATION: This study is a unique application of linked data to the study of health outcomes of joint replacement at the population level. Outcomes of joint replacement differed by the initial diagnosis or reason for the surgery. For patients with osteoarthritis, poorer post-operative health outcomes were associated with co-morbidites and with being underweight.

More doctors or better care?

The Canadian Medical Association's More Doctors, More Care campaign seeks to align physician supply targets with policy decisions elsewhere in the Organisation for Economic Co-operation and Development (OECD). Using OECD data for 19 countries to assess the relationship between physician supply and healthcare outcomes, we have determined that there is no association between avoidable mortality and overall physician supply. Similarly, there is no relationship between avoidable mortality and general practitioners and family physicians per capita, specialists per capita, nurses per capita, doctors and nurses per capita or health expenditures per capita. These findings should move us to recognize that (a) more doctors will not necessarily translate into better healthcare outcomes for Canadians and (b) it is in Canadians' better interests that we instead focus on realizing opportunities to improve access to high-quality care and to ensure that changes in physician turnover do not threaten the current generalist-to-specialist mix.

Use of medical services by methylphenidate-treated children in the general population.

OBJECTIVES: To examine selected medical services for children treated for attention-deficit/hyperactivity disorder (ADHD) in a general population setting with universal health insurance. DESIGN: Retrospective analysis of administrative prescription and health services databases spanning from 1990 to 1996. SETTING: British Columbia, Canada. PATIENTS: Children (<19 years of age) who had received the psychostimulant methylphenidate (MPH; Ritalin) on a chronic basis (chronic-MPH group), who had received MPH on any other basis (nonchronic-MPH group), and who were in a no-MPH comparison group. MAIN OUTCOME MEASURES: The number of individuals who received any of the following services based on claims submitted by qualified practitioners: 1) emergency care, 2) critical care, 3) injury-related diagnostic and treatment services, 4) complementary and alternative medical (CAM) care, and 5) other diagnostic and treatment services (audiometry and allergy testing). RESULTS: Prevalence of services users was higher among MPH-treated than nontreated children for all types of services (except critical care services in the chronic-MPH group) after adjusting for effects of age, sex, socioeconomic status, and geographic setting, with odds ratios ranging from 1.49 to 3.17. There were no differences between the 2 MPH-treated groups. CONCLUSIONS: Children treated with MPH for ADHD or presumed ADHD are more frequent users of a wide range of medical services than are other children. Findings support and extend existing evidence of increased use of medical services by this population of children. Findings have implications for service planning, including injury prevention, with these children. High utilization of audiometric, allergy, and CAM services warrants further scrutiny.
