Efficiency of Ontario primary care physicians across payment models: a stochastic frontier analysis

The impact of rurality on vulvodynia diagnosis and management: Primary care provider and patient perspectives

Objective

The objective of this study was to better understand how rurality impacts the knowledge, diagnosis and management of vulvodynia by primary care providers (PCPs) practising in the geographically disparate province of Newfoundland and Labrador, Canada.

Design

This was a qualitative case study using questionnaires and semi-structured interviews with PCPs, compared with semi-structured focus groups and interviews with vulvodynia patients conducted in a previous study phase.

Results

Ten family physicians and 6 nurse practitioners participated. Over half had baseline knowledge that vulvodynia has a relatively high prevalence, but most underestimated the likelihood they would see a patient with vulvodynia in their practice. Three barriers to discussing and managing vulvodynia emerged: (1) discomfort initiating sexual/vulvar health conversations; (2) concerns about protecting patient privacy and confidentiality; and (3) time constraints and building therapeutic relationships. These issues were largely corroborated by previous findings with vulvodynia patients. Rural-informed solutions might include: (1) supporting increased education in vulvodynia and sexual health more broadly, including funding to attend continuing professional education and developing more clinical tools; (2) following practice guidelines regarding standardised initiation of sexual health conversations; (3) incentivising retention of rural providers and extending appointment times by reconsidering fee-for-service structures; and (4) researching a tailored vulvodynia toolkit and the potential advantage of mobile health units.

Conclusion

Rurality exacerbates common concerns in the identification and management of vulvodynia. Acting on recommended solutions may address the impact of rurality on the provision of timely care for those experiencing vulvodynia and other sexual health concerns.

Toward a 'green allopathy'? Naturopathic paradigm and practice in Ontario, Canada

Epistemic tensions have long been evident within naturopathy, a heterodox healthcare occupation licensed across much of North America. Naturopaths less inclined toward bioscientific explanatory and evidentiary norms have long used the trope of the 'green allopath' to critique the practices of their more biomedically- (i.e., 'allopathically') inclined colleagues. Using the 'green allopathy' narrative as a conceptual starting point, this work uses a qualitatively-driven, mixed methods design involving interviews (n = 17) and a census-style survey (n = 366) to characterize the paradigmatic and practice patterns of licensed naturopaths in Ontario, Canada between 2017 and 2019. At odds with many interviewees' accounts, survey results suggest that the occupation's overall epistemic character, aligned with the concept of holism, has not changed much over the last two decades. Nevertheless, findings suggest notable changes in Ontario naturopaths' clinical practice patterns over the same period, including: more frequent use of botanical medicines, nutritional supplements and acupuncture; less frequent use of physical medicine (e.g., massage, hydrotherapy); and, an overall reduction in homeopathic usage. Controlling for other factors, older naturopaths are more likely to rely often on non-biomedical diagnostic modes (p = 0.042), suggesting an emerging shift, in practice, toward a 'green allopathy'. Naturopaths' widespread ongoing engagement with therapeutic modalities whose epistemic premises diverge strongly from conventional biomedicine (e.g., homeopathy, East Asian medicine), appears mediated by the increasing body of related bioscientific evidence, and by gender and age (p-values <0.05). Gender and age also significantly predict naturopaths' alignment with more pharmaceutically-oriented care (p values < 0.05). Though naturopathy's 'green allopathization' appears underway, the demographic predominance of women within the profession may temper this trend in the years ahead.

How the Gender Wage Gap for Primary Care Physicians Differs by Compensation Approach : A Microsimulation Study

BACKGROUND

The physician gender wage gap may be due, in part, to productivity-based compensation models that undervalue female practice patterns.

OBJECTIVE

To determine how primary care physician (PCP) compensation by gender differs when applying existing productivity-based and alternative compensation models.

DESIGN

Microsimulation.

SETTING

2016 to 2019 national clinical registry of 1222 primary care practices.

PARTICIPANTS

Male and female PCPs matched on specialty, years since medical school graduation, practice site, and sessions worked.

MEASUREMENTS

Net annual, full-time-equivalent compensation for male versus female PCPs, under productivity-based fee-for-service, panel size-based capitation without or with risk adjustment, and hybrid payment models. Microsimulation inputs included patient and visit characteristics and overhead expenses.

RESULTS

Among 1435 matched male (n = 881) and female (n = 554) PCPs, female PCP panels included patients who were, on average, younger, had lower diagnosis-based risk scores, were more often female, and were more often uninsured or insured by Medicaid rather than by Medicare. Under productivity-based payment, female PCPs earned a median of $58 829 (interquartile range [IQR], $39 553 to $120 353; 21%) less than male PCPs. This gap was similar under capitation ($58 723 [IQR, $42 141 to $140 192]). It was larger under capitation risk-adjusted for age alone ($74 695 [IQR, $42 884 to $152 423]), for diagnosis-based scores alone ($114 792 [IQR, $49 080 to $215 326] and $89 974 [IQR, $26 175 to $173 760]), and for age-, sex-, and diagnosis-based scores ($83 438 [IQR, $28 927 to $129 414] and $66 195 [IQR, $11 899 to $96 566]). The gap was smaller and nonsignificant under capitation risk-adjusted for age and sex ($36 631 [IQR, $12 743 to $73 898]).

LIMITATION

Panel attribution based on office visits.

CONCLUSION

The gender wage gap varied by compensation model, with capitation risk-adjusted for patient age and sex resulting in a smaller gap. Future models might better align with primary care effort and outcomes.

Approaches to Measure Efficiency in Primary Care: A Systematic Literature Review

BACKGROUND

Primary care in England is facing increasing pressure due to the increasing number and complexity of consultations and the declining number of doctors per head of population. The improvement of primary care efficiency and productivity should be a priority, to ensure that future investments in the medical workforce can cope with the increasingly large and complex demand for care.

OBJECTIVES

This paper presents a systematic literature review of studies that define or measure efficiency in primary care in high-income settings. The review of the existing definitions of primary care efficiency and their limitations will inform future research on the measurement of efficiency in primary care in England and its determinants.

METHODS

Literature searches were performed on Embase, Medline, and EconLit in January 2020. The records that passed the screening were reviewed in full text, and data on the study settings, the efficiency definition, and the efficiency analysis were extracted.

RESULTS

Of the 2590 non-duplicate records retrieved from the searches, 38 papers were included in the analysis. The volume of the literature on primary care efficiency has evolved significantly from the 1980s, with the majority of the published studies focussing on European health systems. The setting most often analysed was primary care centres. Output was usually expressed using measures of primary care utilisation, with or without quality adjustments. Reference to the health outcomes achieved was, however, limited. Inputs were more commonly expressed in labour terms, while the exogenous variables related either to the characteristics of the patient population or the organisation of primary care. While all studies included an analysis of technical efficiency, consideration of allocative or cost efficiency or the determinants of productivity (e.g. technological change, skill mix) was rare.

CONCLUSIONS

The main limitations that future research on primary care efficiency should address relate to the definition of output. Current approaches to measure the impact on health and the multiple dimensions of output are not sufficient to represent the valued output of primary care. In light of the recent changes in the model of primary care delivery in England, future research should also investigate the impact of technological change on productivity and the scope for substitution across staff roles.

The Induced Productivity Decline Hypothesis: More Physicians, Higher Compensation and Fewer Services

Public outrage regarding physician shortages during the past two decades have led to policies aimed at significantly increasing physician supply, yet access remains elusive. In this paper, we examine this puzzling trend and the causes underlying it by analyzing physician supply, compensation and productivity and the reasons behind productivity decline. We hypothesize that excess physician compensation beyond a target income induces productivity decline. In contrast to a wage–productivity gap for the average Canadian worker (where productivity has increased but compensation has not kept pace), physicians are experiencing a “reverse wage–productivity gap” whereby compensation is increasing but productivity is decreasing, resulting in more physicians, higher compensation and fewer services. We conclude by discussing potential policy options to address how best to provide timely access to medical care for Canadians while keeping physician healthcare expenditures at sustainable levels.

Disparities in Physician Compensation by Gender in Ontario, Canada

IMPORTANCE

Men and women should earn equal pay for equal work. An examination of the magnitude of pay disparities could inform strategies for remediation.

OBJECTIVE

To examine gender-based differences in pay within a large, comprehensive physician population practicing within a variety of payment systems.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study used data from the Ontario Health Insurance Plan (OHIP) in the 2017 to 2018 fiscal year to estimate differences in gross payments between men and women physicians in Ontario, Canada. Pay gaps were calculated annually and daily. Regression analyses were used to control for observable practice characteristics that could account for individual differences in daily pay. In Canada's largest province, Ontario, medical services are predominantly provided by self-employed physicians who bill the province's single payer, OHIP. All physicians who submitted claims to OHIP were included. Data were analyzed from January 2020 to July 2021.

EXPOSURES

Physician gender, obtained from the OHIP Corporate Provider Database. Gender is recorded as male or female.

MAIN OUTCOMES AND MEASURES

Gross clinical payments were tabulated for individual physicians on a daily and annual basis in conjunction with each physician's practice characteristics, setting, and specialty.

RESULTS

A total of 31 481 physicians were included in the study sample (12 604 [40.0%] women; 18 877 [60.0%] men; mean [SD] time since graduation, 23.3 [13.6] years), representing 99% of active physicians in Ontario. The unadjusted differences in clinical payments between male and female physicians were 32.8% (95% CI, 30.8%-34.6%) annually and 22.5% (95% CI, 21.2%-23.8%) daily. After accounting for practice characteristics, region, and specialty, the overall daily payment gap was 13.5% (95% CI, 12.3%-14.8%). The pay gap persisted with differing magnitudes when examined by specialty (ranging from 6.6% to 37.6%), practice setting (8.3% to 17.2%), payment model (13.4% to 22.8% for family medicine; 8.0% to 11.6% for other specialties), and rurality (8.0% to 16.5%).

CONCLUSIONS AND RELEVANCE

This cross-sectional study examined differences in magnitude of annual and daily payment gaps and between unadjusted and adjusted gaps. Comparing the gaps for different specialties, geography, and payment systems illustrated the complexity of the issue by showing that the pay gap varied for physicians in different practice settings. As such, multiple directed interventions will be necessary to ensure that all physicians are paid equally for equal work, regardless of gender.

Primary care of mothers and infants by the same or different physicians: a population-based cohort study

BACKGROUND

Different primary care delivery models exist for mothers and their infants. We examined whether primary care system performance measures differed when mother-infant dyads received primary care from the same or different providers.

METHODS

We conducted a population-based cohort study using Ontario health administrative data from 2004 to 2016. We included primiparous women and their singleton term infants and classified the primary care practitioners who provided the majority of care to the infant and the mother as concordant (same family physician for both; reference group), discordant (a different family physician for each) or pediatrician (pediatrician for the child, family physician for the mother). The primary outcome was nonobstetric maternal hospital admissions between 42 days and 2 years after delivery.

RESULTS

Among 481 721 mother-child pairs, 239 033 (49.6%) received concordant care, 114 006 (23.7%) received discordant care, and 128 682 (26.7%) received pediatrician care. Mothers in the pediatrician group were older and had greater comorbidity. Relative to concordant care, maternal nonobstetric hospital admissions occurred similarly under discordant care (adjusted odds ratio [OR] 1.00, 95% confidence interval [CI] 0.96-1.04) and in the pediatrician group (adjusted OR 0.99, 95% CI 0.95-1.02). Maternal deaths were similar under discordant care (adjusted OR 1.00, 95% CI 0.62-1.63) but lower in the pediatrician group (adjusted OR 0.55, 95% CI 0.34-0.89). Maternal primary care visits were lower in both the discordant group (adjusted relative risk [RR] 0.68, 95% CI 0.68-0.69) and the pediatrician group (adjusted RR 0.75, 95% CI 0.75-0.76). Healthy children were more likely to miss the enhanced 18-month well-baby visit under discordant care (adjusted OR 1.06, 95% CI 1.03-1.09) but less likely to miss this visit under pediatrician care (adjusted OR 0.47, 95% CI 0.46-0.49).

INTERPRETATION

Concordant care provided to a new mother and her infant by the same family physician was not associated with better primary care health system performance. The reason that pediatric primary care is associated with better maternal and child outcomes remains to be determined.

Nonparametric estimation of a primary care production function in urban Brazil

BACKGROUND

The Brazilian public health system is one of the largest health systems in the world, with a mandate to deliver medical care to more than 200 million Brazilians. The objective of this study is to estimate a production function for primary care in urban Brazil. Our goal is to use flexible estimates to identify heterogeneous returns and complementarities between medical capital and labor.

METHODS

We use a large dataset from 2012 to 2016 (with more than 400 million consultations, 270 thousand physicians, and 11 thousand clinics) to nonparametrically estimate a primary care production function and calculate the elasticity of doctors' visits (output) to two inputs: capital stock (number of clinics) and labor (number of physicians). We benchmark our nonparametric estimates against estimates of a Cobb-Douglas (CD) production function. The CD model was chosen as a baseline because it is arguably the most popular parametric production function model. By comparing our nonparametric results with those from the CD model, our paper shed some light on the limitations of the parametric approach, and on the novelty of nonparametric insights.

RESULTS

The nonparametric results show significantly heterogeneity of returns to both capital and labor, depending on the scale of operation. We find that diseconomies of scale, diminishing returns to scale, and increasing returns to scale are possible, depending on the input range.

CONCLUSIONS

The nonparametric model identifies complementarities between capital and labor, which is essential in designing efficient policy interventions. For example, we find that the response of primary care consultations to labor is steeper when capital level is high. This means that, if the goal is to allocate labor to maximize increases in consultations, adding physicians in cities with a high number of clinics is preferred to allocating physicians to low medical infrastructure municipalities. The results highlight how the CD model hides useful policy information by not accounting for the heterogeneity in the data.

Models of Care and Team Activities in the Delivery of Transgender Primary Care: An Ontario Case Study

Purpose: Transgender individuals experience barriers accessing primary care. In Ontario, primary care is delivered through a variety of delivery models. Literature supports team delivery of primary care for transgender individuals, yet little is known about care delivery in Ontario and the role of primary care teams. We intend to explore how primary care for transgender individuals is delivered within the different primary care models in Ontario and the roles primary care team members enact in care delivery, barriers, enablers, and clinical competence of practitioners in delivering transgender care.

Methods: Case study methodology was used to compare transgender care across three Ontario primary care models. Key informants identified cases known to provide transgender care for case selection. Qualitative interviews were conducted. Documentary evidence and field notes were collected.

Results: Practitioners clearly articulated their role and activities they were responsible for in providing care, however, they tended to work independently. In cases with an interdisciplinary team there was limited collaboration. Nurse practitioners, physicians, and counselors contributed most to the delivery of care. Key challenges included lack of service coordination within organizations, and the need for practitioner education. Continuing educational sessions, guidelines, and mentorship aided capacity building.

Conclusions: Providing primary care to transgender individuals is within the scope of practice for primary care practitioners and can be part of routine care delivered in different models of care. Primary care team collaboration can be strengthened by regular team meetings. Professional training needs to include transgender education and continuing education opportunities need development.

Exploring the implementation and delivery of primary care services for transgender individuals in Ontario: case study protocol

Background:

Historically transgender adults have experienced barriers in accessing primary care services. In Ontario, Canada, health care for transgender adults is accessed through primary care; however, a limited number of practitioners provide care, and patients are often waiting and/or traveling great distances to receive care. The purpose of this protocol is to understand how primary care is implemented and delivered for transgender adults. The paper presents how the case study method can be applied to explore implementation of health services delivery for the transgender population in primary care.

Methods:

Case study methodology will be used to explore this phenomenon in different primary care contexts. Normalization Process Theory is used as a guide. Three cases known to provide transgender primary care and represent different Ontario primary care models have been identified. Comparing transgender care implementation and delivery across different models is vital to understanding how care provision to this population can be supported. Qualitative interviews will be conducted. Participants will also complete the NoMAD (NOrmalization MeAsure Development) survey, a tool measuring implementation processes. The tool will be modified to explore the implementation of primary care services for transgender individuals. Documentary evidence will be collected. Cross-case synthesis will be completed to compare the cases.

Discussion:

Findings will provide an Ontario perspective on the implementation and delivery of primary care for transgender adults in different primary care models. Results may be applicable to other primary care settings in Canada and other nations with similar systems. Barriers and facilitators in delivery and implementation will be identified. Providing an understanding and increasing awareness of the implementation and delivery of primary care may help to reduce the invisibility and disparities transgender individuals experience when accessing primary care services. Understanding delivery of care could allow care providers to implement primary care services for transgender individuals, improving access to health care for this vulnerable population.

Planning for the Rheumatologist Workforce: Factors Associated With Work Hours and Volumes

OBJECTIVE

The aim of this study was to evaluate factors associated with rheumatologists' clinical work hours and patient volumes based on a national workforce survey in rheumatology.

METHODS

Adult rheumatologists who participated in a 2015 workforce survey were included (n = 255). Univariate analysis evaluated the relationship between demographics (sex, age, academic vs. community practice, billing fee for service vs. other plan, years in practice, retirement plans) and workload (total hours and number of ½-day clinics per week) or patient volumes (number of new and follow-up consults per week). Multiple linear regression models were used to evaluate the relationship between practice type, sex, age, and working hours or clinical volumes.

RESULTS

Male rheumatologists had more ½-day clinics (p = 0.05) and saw more new patients per week (p = 0.001) compared with females. Community rheumatologists had more ½-day clinics and new and follow-up visits per week (all p < 0.01). Fee-for-service rheumatologists reported more ½-day clinics per week (p < 0.001) and follow-ups (p = 0.04). Workload did not vary by age, years in practice, or retirement plans. In multivariate analysis, community practice remained independently associated with higher patient volumes and more clinics per week. Female rheumatologists reported fewer clinics and fewer follow-up patients per week than males, but this did not affect the duration of working hours or new consultations. Age was not associated with work volumes or hours.

CONCLUSIONS

Practice type and rheumatologist sex should be considered when evaluating rheumatologist workforce needs, as the proportion of female rheumatologists has increased over time and alternative billing practices have been introduced in many centers.

"Primary care is primary care": Use of Normalization Process Theory to explore the implementation of primary care services for transgender individuals in Ontario

BACKGROUND

In Ontario, Canada, healthcare for transgender individuals is accessed through primary care; however, there are a limited number of practitioners providing transgender care, and patients are often on waiting lists and/or traveling great distances to receive care. Understanding how primary care is implemented and delivered to transgender individuals is key to improving access and eliminating healthcare barriers. The purpose of this study is to understand how the implementation of primary care services for transgender individuals compares across various models of primary care delivery in Ontario.

METHODS

A qualitative, exploratory, multiple-case study guided by Normalization Process Theory (NPT) was used to compare transgender care delivery and implementation across three primary care models. Three cases known to provide transgender primary care and represent different primary care models in Ontario, Canada (i.e., family health team, community health centre, fee-for service physician) were explored. The NoMAD survey, a tool to measure implementation processes, and qualitative interviews with primary care practitioners and allied healthcare staff were administered.

RESULTS

Using the NPT framework to guide analysis, key themes emerged about successful implementation of primary care services for transgender individuals. These themes include creating a safe space for patients, identifying gaps in services, understanding practitioners' roles, and the need for more training and education in transgender care for practitioners.

CONCLUSIONS

Primary care services for transgender individuals can and should be delivered in all models of primary care. Training and awareness for healthcare practitioners are needed to develop capacity in providing primary care to transgender individuals. A greater number of practitioners and organizations are needed to take on this work, embedding and normalizing transgender care into routine practice to address barriers to access and improve quality of care for transgender individuals.

The primary care and other health system use of home care patients: a retrospective cohort analysis

BACKGROUND

Robust and integrated primary care and home care are core components of effective chronic disease management in the community. We described the primary care and other health system use by a cohort of home care patients.

METHODS

We conducted a population-based retrospective cohort study of patients who received publicly funded home care in Ontario, Canada, from October 2014 to September 2016. Primary outcomes were primary care physician visits including coordination with home care, home visits and visits after hours or on weekends or holidays within 6 months of a home care assessment. Secondary outcomes included specialist physician visits, emergency department use, home care visits and placement in a long-term care home. Multivariable models examined associations between patient characteristics and subsequent primary care use.

RESULTS

There were 226 054 home care patients in our cohort, with a median age of 81 years. Following assessment, home care patients visited primary care physicians at a rate of 0.78 visits per month. Physician-based home care coordination codes were billed for 3.9% of patients. Primary care home visits were received by 13.1% of patients, and 15.1% of patients used primary care after hours or on weekends or holidays.

INTERPRETATION

Patients receiving publicly funded home care frequently visited a primary care physician. Physician billings for coordination between primary care and home care were infrequent but were more common in interprofessional primary care practices. Physician home visits were more likely to be received by the oldest and most functionally impaired patients, suggesting that home visits are responsive to the needs of home care patients.
