Evaluating the cost of NP-led vs. GP-led primary care in British Columbia.

In 2020, British Columbia (BC) opened four pilot Nurse Practitioner Primary Care Clinics (NP-PCCs) to improve primary care access. The aim of this economic evaluation is to compare the average cost of care provided by Nurse Practitioners (NPs) working in BC's NP-PCCs to what it would have cost the government to have physicians provide equivalent care. Comparisons were made to both the Fee-For-Service (FFS) model and BC's new Longitudinal Family Physician (LFP) model. The analyses relied on administrative data, mostly from the Medical Services Plan (MSP) and Chronic Disease Registry (CDR) via BC's Health Data Platform. Results show the cost of NPs providing care in the NP-PCCs is slightly lower than what it would cost to provide similar care in medical clinics staffed by physicians paid through the LFP model. This suggests that the NP-PCC model is an efficient approach to increase accessibility to primary care services in BC and should be considered for expansion across the province.

Productivity Decline or Administrative Avalanche? Examining Factors That Shape Changing Workloads in Primary Care.

Background: In Canada, family physicians (FPs) per capita have increased but so have access challenges. We explored changes in population characteristics, service delivery and FP practice that may help understand these trends. Methods: We used linked administrative data in British Columbia to describe changes in patient ages and comorbidities, hospitalizations and receipt of services that may require FP coordination, review and/or follow-up: prescriptions dispensed, laboratory tests, diagnostic imaging (radiology and ultrasound), specialist visits and emergency department visits. We estimate the number of FPs delivering community-based comprehensive care and report changes in service volume per community-based FP visit. Results: Between 1999/2000 and 2017/2018, people experienced fewer days in hospital, but the number of treated comorbidities, day surgeries and other services requiring FP coordination increased over and above the expected levels attributed to population aging. While the total number of FPs per capita have increased, numbers in community-based care have not and visits per physician have fallen. Increases in services that may involve FP coordination per community-based FP visit ranged from 32.2% for diagnostic radiology to 122.1% for lab tests. Conclusion: Findings suggest substantially increased coordination workload per FP visit. Ongoing impacts of population aging and changing service delivery on primary care workload require further examination.

'We don't have the right to get sick': A qualitative study of gaps in public health insurance among Im/migrant women in British Columbia, Canada.

Globally, the exclusion of im/migrants from public health care systems remains a significant health and human rights issue, calling into question claims of 'universality' of public health systems where eligibility for coverage is determined by immigration status. We aimed to describe lived experiences of health insurance coverage and the health and social impacts of gaps in health insurance amongst im/migrant women in British Columbia (BC), Canada. This analysis draws on qualitative in-depth interviews (n = 78) with im/migrant women and im/migrant-focused service providers (n = 10) conducted between July 2018-March 2021 in Metro Vancouver, BC, as part of a larger community-based, mixed-methods study of im/migrants' health access (IRIS). In contrast to common perceptions of Canada's health system as 'universal', participants faced multifaceted barriers to health insurance and necessary healthcare for themselves and their families following arrival in BC. Narratives highlighted the ways in which ineligibility for public health insurance coverage resulted in unmet needs for essential sexual and reproductive health and preventive care among im/migrant women, children, and families. Participants also described ineligibility for public health insurance as resulting in a high economic burden, and that exclusion from public health insurance perpetuated experiences of discrimination, invisibility, and exclusion from systems of care amongst im/migrant participants. Despite these structural challenges, participant narratives highlighted the crucial role of community-based supports for minimizing harm and navigating oppressive immigration and health systems. Changes to immigration and health policies are required to remove barriers to public health care for im/migrant women and ensure that Canada's health system is accessible to all. Expanding health insurance options to cover all residents and decoupling health insurance eligibility from immigration status are recommended, alongside implementation of 'Sanctuary' policies at the local level.

"It's not just about being here, but what brought you here": A qualitative study of the role of migration experiences in shaping im/migrant women's access to healthcare.

This qualitative study aimed to understand how migration experiences shape im/migrant women's needs, desire for, and expectations of healthcare in the British Columbia (BC), Canada context. Interviews with 33 im/migrant women (December 2018-January 2020) highlighted that traumatic experiences across migration increased healthcare needs; insufficient prior health system information contributed to poor experiences; and comparative healthcare experiences across places shaped future healthcare expectations. We use the BC setting to demonstrate the need to abide by global commitments to protect people during migration, train providers in trauma-informed care, develop health assessments that center migration journeys, and appropriately fund im/migrant-serving community organizations.

Population segments as a tool for health care performance reporting: an exploratory study in the Canadian province of British Columbia.

BACKGROUND: Primary care serves all age groups and individuals with health states ranging from those with no chronic conditions to those who are medically complex, or frail and approaching the end of life. For information to be actionable and guide planning, there must be some population disaggregation based on differences in expected needs for care. Promising approaches to segmentation in primary care reflect both the breadth and severity of health states, the types and amounts of health care utilization that are expected, and the roles of the primary care provider. The purpose of this study was to assess population segmentation as a tool to create distinct patient groups for use in primary care performance reporting. METHODS: This cross-sectional study used administrative data (patient characteristics, physician and hospital billings, prescription medicines data, emergency department visits) to classify the population of British Columbia (BC), Canada into one of four population segments: low need, multiple morbidities, medically complex, and frail. Each segment was further classified using socioeconomic status (SES) as a proxy for patient vulnerability. Regression analyses were used to examine predictors of health care use, costs and selected measures of primary care attributes (access, continuity, coordination) by segment. RESULTS: Average annual health care costs increased from the low need ($ 1460) to frail segment ($10,798). Differences in primary care cost by segment only emerged when attributes of primary care were included in regression models: accessing primary care outside business hours and discontinuous primary care (≥5 different GP's in a given year) were associated with higher health care costs across all segments and higher continuity of care was associated with lower costs in the frail segment (cost ratio = 0.61). Additionally, low SES was associated with higher costs across all segments, but the difference was largest in the medically complex group (cost ratio = 1.11). CONCLUSIONS: Population segments based on expected need for care can support primary care measurement and reporting by identifying nuances which may be lost when all patients are grouped together. Our findings demonstrate that variables such as SES and use of regression analyses can further enhance the usefulness of segments for performance measurement and reporting.

Predicting the Cost of Health Care Services: A Comparison of Case-mix Systems and Comorbidity Indices That Use Administrative Data.

BACKGROUND: Case-mix systems and comorbidity indices aggregate clinical information about patients over time and are used to characterize need for health care services. These tools were validated for their original purpose, but those purposes are varied, and they have not been compared directly in the context of predicting costs of health care services. OBJECTIVE: To compare predictions of next-year health care service costs across 4 tools, including: the Johns Hopkins Adjusted Clinical Groups (ACG), the Elixhauser Comorbidity Index, Charlson-Deyo Comorbidity Index, and the Canadian Institute for Health Information (CIHI) population grouper. METHODS: British Columbia administrative data from fiscal years 2012-2013 were used to generate case-mix variables and the comorbidity indices. Outcome variables include next-year (2013-2014) total, physician, acute care, and pharmaceutical costs, Outcomes were modeled using 2-part models. Performance was compared using adjusted R, root mean squared error, and mean absolute error using the predicted and the actual next-year cost. RESULTS: Models including the CIHI grouper (239 conditions) and ACG system had similar performance in most cost categories and slightly better fit than Charlson Comorbidity Index (CCI) and Elixhauser Comorbidity Index (ECI). Adding a dummy variable for nonusers in the models for CCI and ECI increased R values slightly. CONCLUSIONS: All these systems have empirical support for use in predicting health care costs, despite in some cases being developed for other purposes. No system is particularly effective at predicting next-year acute care cost, likely because acute events are often by definition unexpected. The freely available ECI and CCI comorbidity indices implemented using the highest-performing methods developed here may be a good choice in many circumstances.

Access to Primary Care and Internet Searches for Walk-In Clinics and Emergency Departments in Canada: Observational Study Using Google Trends and Population Health Survey Data.

BACKGROUND: Access to primary care is a challenge for many Canadians. Models of primary care vary widely among provinces, including arrangements for same-day and after-hours access. Use of walk-in clinics and emergency departments (EDs) may also vary, but data sources that allow comparison are limited. OBJECTIVE: We used Google Trends to examine the relative frequency of searches for walk-in clinics and EDs across provinces and over time in Canada. We correlated provincial relative search frequencies from Google Trends with survey responses about primary care access from the Commonwealth Fund's 2016 International Health Policy Survey of Adults in 11 Countries and the 2016 Canadian Community Health Survey. METHODS: We developed search strategies to capture the range of terms used for walk-in clinics (eg, urgent care clinic and after-hours clinic) and EDs (eg, emergency room) across Canadian provinces. We used Google Trends to determine the frequencies of these terms relative to total search volume within each province from January 2011 to December 2018. We calculated correlation coefficients and 95% CIs between provincial Google Trends relative search frequencies and survey responses. RESULTS: Relative search frequency of walk-in clinic searches increased steadily, doubling in most provinces between 2011 and 2018. Relative frequency of walk-in clinic searches was highest in the western provinces of British Columbia, Alberta, Saskatchewan, and Manitoba. At the provincial level, higher walk-in clinic relative search frequency was strongly positively correlated with the percentage of survey respondents who reported being able to get same- or next-day appointments to see a doctor or a nurse and inversely correlated with the percentage of respondents who reported going to ED for a condition that they thought could have been treated by providers at usual place of care. Relative search frequency for walk-in clinics was also inversely correlated with the percentage of respondents who reported having a regular medical provider. ED relative search frequencies were more stable over time, and we did not observe statistically significant correlation with survey data. CONCLUSIONS: Higher relative search frequency for walk-in clinics was positively correlated with the ability to get a same- or next-day appointment and inversely correlated with ED use for conditions treatable in the patient's regular place of care and also with having a regular medical provider. Findings suggest that patient use of Web-based tools to search for more convenient or accessible care through walk-in clinics is increasing over time. Further research is needed to validate Google Trends data with administrative information on service use.

Classifying physician practice style: a new approach using administrative data in British Columbia.

BACKGROUND: Primary medical care is changing-more female providers, desire for better work-life balance, and increasing availability of walk-in clinics have altered service delivery. There is no uniform physician practice style, and understanding service availability and delivery requires analysis of family physicians' practice patterns, rather than just physician counts. METHODS: This paper offers a new approach for describing the practice habits of primary care physicians. We use administrative data to identify activities associated with acting as "most responsible" physicians. We used British Columbia's administrative health care data from 2007/2008 to 2011/2012 to derive information regarding physicians, patients, and service delivery. We developed 5 variables to describe practice style: referrals, oversight, screening, initial prescribing for long-term medications, and repeat visits. Cluster analysis revealed 3 distinct groups of physicians. RESULTS: Only 24% of the primary care physicians were assigned to the high-responsibility group, whereas 36% and 39% were in the low-responsibility and mixed-practice groups, respectively. All cluster variables follow a similar pattern, with the high-responsibility and low-responsibility physicians many multiples apart on the means and the mixed group falling in between. Several forms of sensitivity analysis confirmed the robustness of these results. CONCLUSIONS: Physician practice patterns influence the effective supply of primary care. The fact that more than one third of British Columbia physicians are identified as "low responsibility" has implications for the delivery of primary care, both in ensuring that people have access to regular care and in insuring high-quality and comprehensive care.

Capacity development in health systems and policy research: a survey of the Canadian context.

BACKGROUND: Over the past decade, substantial global investment has been made to support health systems and policy research (HSPR), with considerable resources allocated to training. In Canada, signs point to a larger and more highly skilled HSPR workforce, but little is known about whether growth in HSPR human resource capacity is aligned with investments in other research infrastructure, or what happens to HSPR graduates following training. METHODS: We collected data from the Canadian Institutes of Health Research, Canada's national health research funding agency, and the Canadian Association for Health Services and Policy Research on recent graduates in the HSPR workforce. We also surveyed 45 Canadian HSPR training programs to determine what information they collect on the career experiences of graduates. RESULTS: No university programs are currently engaged in systematic follow-up. Collaborative training programs funded by the national health research funding agency report performing short-term mandated tracking activities, but whether and how data are used is unclear. No programs collected information about whether graduates were using skills obtained in training, though information collected by the national funding agency suggests a minority (<30%) of doctoral-level trainees moving on to academic careers. CONCLUSIONS: Significant investments have been made to increase HSPR capacity in Canada and around the world but no systematic attempts to evaluate the impact of these investments have been made. As a research community, we have the expertise and responsibility to evaluate our health research human resources and should strive to build a stronger knowledge base to inform future investment in HSPR research capacity.

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.
