Encounters with Rheumatologists in a Publicly Funded Canadian Healthcare System: A Population-based Study

Improving access to care for rheumatology services in Canada

Rheumatic diseases are becoming increasingly prevalent in Canada, and its associated strain on the healthcare system is expected to increase over the next decades. Furthermore, there is an increasing body of evidence to suggest that access to rheumatology care is currently not meeting established quality of care benchmarks. To frame issues affecting access to care for rheumatology services in Canada, a proposed chronological framework from a rheumatology patient's perspective is proposed. Illustrating principles from a health policy lens including drawing from the stages heuristic framework and multiple streams theory, issues surrounding access to rheumatology assessment, to rheumatological investigations and lastly to appropriate treatment are explored. In particular, the current supply and demand mismatch within the rheumatology workforce presents challenges for patients in accessing rheumatic diseases providers. Potential policy solutions including increasing the pool of rheumatic diseases care providers, enhancing the clinical capacity with extended role providers and increasing uptake of virtual care are discussed. To ameliorate access to rheumatology investigations, the concept of provider education surrounding the appropriateness of investigations and merit-based funding are explored. Lastly, access to rheumatological treatment is framed using biologic therapies as an example, highlighting the policy challenges in biosimilar uptake and associated ethical and political considerations. By using a health policy lens to explore deficiencies within Canada's current system, the overarching goal of this analysis is to set the stage for reasoned and timely solutions in the future.

System-level performance measures of access to rheumatology care: a population-based retrospective study of trends over time and the impact of regional rheumatologist supply in Ontario, Canada, 2002-2019

OBJECTIVE

To determine whether there were improvements in rheumatology care for rheumatoid arthritis (RA) between 2002 and 2019 in Ontario, Canada, and to evaluate the impact of rheumatologist regional supply on access.

METHODS

We conducted a population-based retrospective study of all individuals diagnosed with RA between January 1, 2002 and December 31, 2019. Performance measures evaluated were: (i) percentage of RA patients seen by a rheumatologist within one year of diagnosis; and (ii) percentage of individuals with RA aged 66 years and older (whose prescription drugs are publicly funded) dispensed a disease modifying anti-rheumatic drug (DMARD) within 30 days after initial rheumatologist visit. Logistic regression was used to assess whether performance improved over time and whether the improvements differed by rheumatology supply, dichotomized as < 1 rheumatologist per 75,000 adults versus ≥1 per 75,000.

RESULTS

Among 112,494 incident RA patients, 84% saw a rheumatologist within one year: The percentage increased over time (adjusted odds ratio (OR) 2019 vs. 2002 = 1.43, p < 0.0001) and was consistently higher in regions with higher rheumatologist supply (OR = 1.73, 95% CI 1.67-1.80). Among seniors who were seen by a rheumatologist within 1 year of their diagnosis the likelihood of timely DMARD treatment was lower among individuals residing in regions with higher rheumatologist supply (OR = 0.90 95% CI 0.83-0.97). These trends persisted after adjusting for other covariates.

CONCLUSION

While access to rheumatologists and treatment improved over time, shortcomings remain, particularly for DMARD use. Patients residing in regions with higher rheumatology supply were more likely to access care but less likely to receive timely treatment.

Healthcare utilization and costs for musculoskeletal disorders in Ontario, Canada

OBJECTIVE

To examine the magnitude and costs of ambulatory primary and specialist physician care and hospital service use for musculoskeletal disorders (MSDs) in Canada's largest province, Ontario.

METHODS

Administrative health databases were analyzed for fiscal year 2013-2014 for adults 18+ years, including data on physician services, emergency department (ED) visits and hospitalizations. ICD diagnostic codes were used to identify MSD services. A validated algorithm was used to estimate direct medical costs. Person visit rates and numbers of persons and visits were tabulated by care setting, age and sex, and physician specialty. Data were examined for all MSDs combined as well as specific diagnostic groupings.

RESULTS

Overall, 3.1 million adult Ontarians (28.5%) made 8 million outpatient physician visits associated with MSDs. These included 5.6 million primary care visits. MSDs accounted for 560,000, 12.3%, of all adult ED visits. Total costs for MSD-related care were $1.6 billion, with 12.6% of costs attributed to primary care, 9.2% to specialist care, 8.6% to ED care, 8.5% to day surgery and 61.2% of total costs associated with inpatient hospitalizations. Costs due to arthritis accounted for 40% of total MSD care costs ($639 million). MSD-related imaging costs were $169 million. Including these costs yields a total estimate of $1.8 billion for all MSDs combined.

CONCLUSION

MSDs place a significant and costly burden on the health care system. Health system planning needs to consider the large and escalating demand for care to reduce both the individual and population burden.

Variations in Pediatric Rheumatology Workforce and Care Processes Across Canada

OBJECTIVE

To examine Canadian pediatric rheumatology workforce and care processes.

METHODS

Pediatric rheumatologists and allied health professionals (AHPs) participated. A designee from each academic centre provided workforce information including number of providers, total and breakdown of full-time equivalents (FTE), and triage processes. We calculated the clinical care FTE (cFTE) available per 75,000 (recommended benchmark) and 300,000 (adjusted) children using 2019 census data. The national workforce deficit was calculated as the difference between current and expected cFTEs. Remaining respondents were asked about ambulatory practices.

RESULTS

The response rate of survey A (workforce information) and survey B (ambulatory practice information) was 100% and 54%, respectively. The majority of rheumatologists (91%) practiced in academic centres. The median number of rheumatologists per centre was 3 (IQR:3) and median cFTE was 1.8 (IQR:1.5). The median cFTE per 75,000 was 0.2 (IQR:0.3) with a national deficit of 80 cFTEs. With the adjusted benchmark, there was no national deficit but a regional maldistribution of rheumatologists. All centres engaged in multidisciplinary practices with a median of 4 different AHPs, although the median FTE for AHPs was ≤1. Most centres (87%) utilized a centralized triage process. Of 9 (60%) centres that used an electronic triage process, 6 were able to calculate wait times. Most clinicians integrated quality improvement practices, such as pre-visit planning (68%), post-visit planning (68%), and periodic health outcome monitoring (36-59%).

CONCLUSION

This study confirms a national deficit at the current recommended benchmark. Most rheumatologists work in multidisciplinary teams, but AHP support may be inadequate.

An Advanced Clinician Practitioner in Arthritis Care (ACPAC) Maintains a Positive Patient Experience While Increasing Capacity in Rheumatology Community Care

Purpose

This study describes patient care experiences of solo-rheumatologist and co-managed care models utilizing an Advanced Clinician Practitioner in Arthritis Care-trained Extended Role Practitioner (ACPAC-ERP) in three community rheumatology practices.

Materials and Methods

Patients with inflammatory arthritis (IA) were assigned to care provided by one of three (2 senior, 1 early-career) community-based rheumatologists (usual care), or an ACPAC-ERP (co-managed care) for the 6-months following diagnosis. Patient experiences were surveyed using validated measures of patient satisfaction (Patient Doctor Interaction Scale-PDIS), global ratings of confidence and satisfaction, referral patterns, disease activity (RADAI) and self-perceived disability (HAQ-Disability) as well as demographic information. Practice capacity was evaluated 18-months prior to, and across, the study period.

Results

Of 55 participants (mean age 56.6 years, 61.8% female), 33 received co-managed care. Most participants were diagnosed with rheumatoid arthritis (65.5%) with a median symptom duration of 1.1 years. At 6-months, patients from both models of care were equally satisfied in terms of the information provided (usual care 4.6 vs co-managed care 4.7/5=greater satisfaction), rapport with health-care provider (4.6 vs 4.6/5) and having needs met (4.7 vs 4.5/5). Overall satisfaction was high (87.2 vs 85.3/100=completely satisfied) as was confidence in the system by which care was received (85.0 vs 82.1/100=completely confident). Usual care patients reported higher perceived disability than co-managed patients (HAQ-Disability 0.5 vs 0.2/3=unable to do). Significant differences in overall RADAI score (p=0.014) were found between the two models. The senior rheumatologist, with a previously saturated practice, attained a 37% capacity increase for new patients utilizing the co-managed care model.

Conclusion

The ACPAC-ERP model was equivalent to the solo-rheumatologist model with regard to patient experience and satisfaction. A co-management model utilizing a highly trained ACPAC-ERP can increase capacity in community rheumatology clinics for patients newly diagnosed with IA while maintaining confidence and satisfaction with their care.

Geographic Variation in the Prevalence of Rheumatoid Arthritis in Alberta, Canada

OBJECTIVES

Timely access to rheumatologists remains a challenge in Alberta, a Canadian province with vast rural areas, whereas rheumatologists are primarily clustered in metro areas. To address the goal of timely and equitable access to rheumatoid arthritis (RA) care, health planners require information at the regional and local level to determine the RA prevalence and the associated health care needs.

METHODS

Using Alberta Health administrative databases, we identified RA-prevalent cases (April 1, 2015-March 31, 2016) on the basis of a validated case definition. Age- and sex-standardized prevalence rates per 1000 population members and the standardized rates ratio (SRR) were calculated. We applied Global Moran's I and Gi* hotspot analysis using three different weight matrices to explore the geospatial pattern of RA prevalence in Alberta.

RESULTS

Among 38 350 RA cases (68% female; n = 26 236), the prevalence rate was 11.81 cases per 1000 population members (95% confidence interval [CI] 11.80-11.81) after age and sex standardization. Approximately 60% of RA cases resided in metro (Calgary and Edmonton) and moderate metro areas. The highest rate was observed in rural areas (14.46; 95% CI 14.45-14.47; SRR 1.28), compared with the lowest in metro areas (10.69; 95% CI 10.68-10.69; SRR 0.82). The RA prevalence across local geographic areas ranged from 4.7 to 30.6 cases. The Global Moran's I index was 0.15 using three different matrices (z-score 3.96-4.24). We identified 10 hotspots in the south and north rural areas and 18 cold spots in metro and moderate metro Calgary.

CONCLUSION

The findings highlight notable rural-urban variation in RA prevalence in Alberta. Our findings can inform strategies aimed at reducing geographic disparities by targeting areas with high health care needs.

Evaluation of Rheumatology Workforce Supply Changes in Ontario, Canada, from 2000 to 2030

Rheumatology workforces are increasingly challenged by too few physicians in face of the growing burden of rheumatic and musculoskeletal diseases (RMDs). Rheumatology is one of the most frequent non-surgical specialty referrals and has the longest wait times for subspecialists. We used a population-based approach to describe changes in the rheumatology workforce, patient volumes and geographic variation in the supply of and access to rheumatologists, in Ontario, Canada, between 2000 and 2019, and projected changes in supply by 2030. Over time, we observed greater feminization of the workforce and increasing age of workforce members. We identified a large regional variation in rheumatology supply. Fewer new patients are seen annually, which likely contributes to increasing wait times and reduced access to care. Strategies and policies to raise the critical mass and improve regional distribution of supply to effectively provide rheumatology care and support the healthcare delivery of patients with RMDs are needed.

Feminization of the Rheumatology Workforce: A Longitudinal Evaluation of Patient Volumes, Practice Sizes, and Physician Remuneration

OBJECTIVE

To compare differences in clinical activity and remuneration between male and female rheumatologists and to evaluate associations between physician gender and practice sizes and patient volume, accounting for rheumatologists' age, and calendar year effects.

METHODS

We conducted a population-based study in Ontario, Canada, between 2000 to 2015 identifying all rheumatologists practicing as full-time equivalents (FTEs) or above and assessed differences in practice sizes (number of unique patients), practice volumes (number of patient visits), and remuneration (total fee-for-service billings) between male and female rheumatologists. Multivariable linear regression was used to evaluate the effects of gender on practice size and volume separately, accounting for age and year.

RESULTS

The number of rheumatologists practicing at ≥ 1 FTE increased from 89 to 120 from 2000 to 2015, with the percentage of females increasing from 27.0% to 41.7%. Males had larger practice sizes and practice volumes. Remuneration was consistently higher for males (median difference of CAD $46,000-102,000 annually). Our adjusted analyses estimated that in a given year, males saw a mean of 606 (95% CI 107-1105) more patients than females did, and had 1059 (95% CI 345-1773) more patient visits. Among males and females combined, there was a small but statistically significant reduction in mean annual number of patient visits, and middle-aged rheumatologists had greater practice sizes and volumes than their younger/older counterparts.

CONCLUSION

On average, female rheumatologists saw fewer patients and had fewer patient visits annually relative to males, resulting in lower earnings. Increasing feminization necessitates workforce planning to ensure that populations' needs are met.

Trends in mortality and cause-specific mortality among patients with psoriasis and psoriatic arthritis in Ontario, Canada

BACKGROUND

There is limited information about mortality rates among patients with psoriasis and psoriatic arthritis (PsA) in North America and their change over the past 2 decades.

OBJECTIVE

To compare all-cause and cause-specific mortality rates in patients with psoriasis to the general population in Ontario, Canada, from 1996 to 2016.

METHODS

We conducted a population-based, retrospective cohort study of adult residents using administrative health data. All-cause and cause-specific standardized mortality rates, standardized mortality ratios, and excess mortality rates were calculated.

RESULTS

176,858 (2,524 deaths) patients with psoriasis and 15,430 (221 deaths) patients with PsA were identified in 2016. Patients with psoriasis and PsA had standardized excess mortality rates of 1.44 and 2.43 per 1000 population, respectively. Standardized mortality rates decreased by approximately 30% over the study period in both disease groups but remained significantly elevated compared to the general population. The leading causes of death in psoriasis and PsA patients were cancer, circulatory disease, and respiratory conditions.

LIMITATIONS

We were unable to classify patients according to disease severity.

CONCLUSIONS

Despite improvements in psoriasis treatment, the relative excess mortality, which may be related to risk factors for psoriatic disease, remained unchanged, with an average of approximately 1 to 2 extra deaths per 1,000 patients in 2016.
