Modern work patterns of “classic” versus millennial family doctors and their effect on workforce planning for community-based primary care: a cross-sectional survey

Approximately one in six British Columbians do not have a regular family doctor [1], matching the Canadian national average. News reports of patients looking for a family physician and being unable to find one are ubiquitous, and most physician practices are not currently accepting new patients [2‐6]. The gap between demand and supply exists despite a consistent increase in numbers of family physicians per capita since 1986 [7, 8], and stable per-physician remuneration [9, 10]. This suggests that either underlying changes in practice are reducing supply or demand is increasing.

Since federal Medicare legislation was passed in 1966, there have been no substantive structural changes to how primary care is delivered in British Columbia (BC), and it is assumed that the vast majority of physicians are practicing in the “classic” model. We define this as working in a community-based physician-owned and physician-operated practice, either alone or with a small group of physician colleagues, providing comprehensive full-scope care to a large panel of patients under a fee-for-service (FFS) model [11]. Non-physician providers such as registered nurses, nurse practitioners, or other health professionals are not part of classic practices and have not been integrated into the primary care system more broadly.

There are signals, however, that the classic primary care model may no longer reflect how the majority of primary care physicians are practicing, and therefore that measures of supply within the system could be substantially inflated [12]. This could at least partly explain the conflicting observation of both increasing demand and increasing supply. Activity levels and patient panel sizes have declined substantially over time [10]. Fewer physicians are managing inpatient care for their own patients, or are otherwise providing services at non-office-based locations [13, 14], and comprehensiveness of care appears to be declining [14, 15].

Furthermore, there are options available for physicians who do not wish to run a solo or shared private community-based practice, such as hospitalist positions or locum tenens [16‐18], and these roles are becoming more available. Physicians may choose to work in part-time “focused practice” type roles (e.g., sports medicine, palliative care, addiction treatment) [19].

There is also a small but growing body of evidence that suggests that new physicians are structuring their practices differently than more established physicians and that they may be more likely to choose some of these non-classic roles. For example, only 61% of family medicine residents in Western Canada stated that they intended to provide comprehensive care, and a full 28% report that they will focus their practice in specific clinical areas only [19]. Newer physicians provide a different basket of services than their more established counterparts [15, 20]. They are also more likely to prefer non-FFS remuneration and to choose a model that does not involve clinic ownership and management [21, 22].

If physicians working in blended models, clinically focused practice, or full-time hospitalist or locum positions account for a substantial percentage of overall supply of primary care physicians, and particularly if these models are more common among newer-to-practice physicians, there will be fewer physicians remaining to provide longitudinal, comprehensive, community-based primary care now and increasingly so in future. This could help to explain the co-occurring observations of increasing supply with no change in unmet need, but we are unaware of any studies that have examined this either in BC or elsewhere in Canada. The objectives of this cross-sectional survey analysis were to identify and describe current models of primary care practice in a Health Authority in BC and to examine whether and in what ways newer graduates model their practices differently than more established physicians.

In total, 1017 physicians were initially invited to participate in the study. Of these, 584 physicians completed the survey (57.4%; Fig. 1); however, 38 (6.5%) of them subsequently requested that their data be withdrawn. An additional nine (0.9%) responses were removed for physicians reporting that they do not provide any patient care, and six (0.6%) were discarded because of incomplete responses to core practice model questions, leaving a final sample of 525 (51.6%). Of the respondents in that final sample, 56% (291) are women, 21.3% (112) trained outside of Canada, and 21.1% (111) provide at least some care in a rural practice location.

On average, respondents had been in practice for 22.5 years (SD = 13.3), and 131 (25.0%) intend to retire within the next 5 years. Respondents work an average of 44.1 h per week (SD = 15.2), and 30 of those hours (SD = 13.1) were dedicated to direct patient care.

Among respondents, 355 (67.6%) reported doing at least some community-based primary care: 112 (31.6%) provide these services 37.5 h per week or more, 141 (39.7%) between 20 and 37.5 h per week, and 102 (28.7%) less than 20 h per week (Table 1). On average, physicians who reported that their model of practice includes at least some CBPC spent 27 h per week (SD = 16.0) on that work and 18.9 h per week (SD = 15.7) on other work. Of respondents, 42 (11.8%) provide no services in CBPC clinics, despite selecting this as their core model of practice. Among the remaining 170 who reported not providing CBPC, 97 (18.5%) report working entirely in a hospital or inpatient facility and 73 (13.9%) are locums.

At the bivariate level, we observed significant differences among practice models with respect to gender distribution, average years in practice, training location, rural practice location, work hours, and number of practice locations. We observed no difference in provision of call coverage or retirement planning (Table 1). Among the three groups of respondents who provided at least some CPBC, we observed significant bivariate differences in patient panel size; in focused, mixed, or general practice; and in working in at least one hospital/facility or emergency room. More physicians who provide CBPC for less than 20 h per week reported working in clinically focused practice compared with those who work between 20 and 37.5 h per week or more than 37.5 h per week (20.2%, compared to 4.3% and 1.8% respectively). More physicians who work less than 20 h per week also had small patient panel sizes, but work at more locations than those who spend more time providing CBPC.

We found some differences in populations and services across the CBPC groups (Tables 2 and 3). More physicians providing CBPC full time reported providing prenatal and postpartum care than either part-time group. More physicians in this group also reported providing house calls, hospital visits, and residential care, and caring for elders with frailty. A significantly larger percentage of physicians who reported spending less than 20 h per week working in CBPC provide services for individuals with substance use disorders, including treating those disorders and prescribing methadone and buprenorphine/naloxone.

New graduates work more weekly hours (more patient care, and paperwork in particular) than established physicians. They also work in more locations (Table 4). We also found differences between new and established physicians in terms of model of practice, with more new graduates working in locum practice and fewer full-time or mostly in CPBC. New graduates are also more likely to work in mixed practice and less likely to work in focused or general practice models.

Our multivariable analyses found that physicians who trained internationally had significantly higher odds of reporting that some or all of their work is CBPC (some CBPC: OR 2.92, 95% CI 1.70–5.01; full-time CPBC: OR 2.03, 95% CI 1.20–3.43) than physicians who trained in Canada (Table 5). Women had significantly lower odds of providing full-time CBPC (OR 0.37, 95% CI 0.23–0.59). There was no significant difference in the odds of providing any or full-time CBPC between new or established family physicians once we adjusted for the effects of gender, training location, and practice location.

We found that while two thirds of our respondents reported providing at least some CBPC, only 21% of the sample provide that care full time. This substantial move away from the classic general practitioner model suggests that capacity for longitudinal CBPC is much more limited than headcount metrics or billings-based full-time equivalents would suggest. At the same time, only 5% of our sample are working less than 20 h per week, suggesting that those who are spending less than 37.5 h per week doing CBPC are working full-time hours but spending time in non-CBPC locations such as focused practices, inpatient facilities, or emergency rooms (ERs). Furthermore, new graduates work on average 3.5 h per week more than established physicians, in contrast to the commonly heard narrative of millennial family doctors working part time and being a cause for erosion our primary care capacity [26].

This study is one of the few available descriptions of modern work patterns by family physicians in Canada. Existing literature relies heavily on billings data, which has not allowed for description of practice across multiple locations, fails to distinguish between community-based and other venues for delivering primary care, and cannot be used to calculate hours spent working. Even full-time equivalent calculations based on dollars billed, such as those produced by CIHI [27], do not account for whether the work a physician is doing is CBPC, hospitalist work, locum work, or something else. It is also one of the few studies that examine differences in work models and patterns between new graduates and established physicians. While it supports the existing finding that substantial numbers of new graduates do not (or do not intend to) provide comprehensive primary care [28, 29], it extends that work by providing direct comparison with more established physicians.

Our results also suggest that primary care physicians are finding alternative ways to model their practices, shifting away from single-location community-based clinics, despite the lack of formalized structural reform in BC’s primary care system. Assessments of whether these new work patterns are aligned with patient need and what is driving physicians to move away from CBPC are beyond the scope of this paper, but both are critical areas of study that should be undertaken in the future. At a minimum, however, the fact that there is a substantial ongoing population need for increased access to longitudinal CBPC suggests that greater attention needs to be paid to what jobs are being offered to family physicians and how they compare to the models of practice physicians are creating for themselves.

Other ways to address the unmet need for primary care may involve a move to an interdisciplinary team-based model of care and formally incorporating registered nurses, nurse practitioners, and other non-physician providers into the primary care system. The BC Ministry of Health has recently started to implement a substantial suite of reforms that includes a core focus on interdisciplinary teams [23‐25], organized into Patient Medical Homes [30]. The Patient Medical Homes will still be physician-owned and physician-operated, and FFS remuneration is expected to be the dominant form of remuneration. While in theory this could reduce the number of physicians required to meet population health needs, the extent of the uptake of these voluntary reforms among new graduates and established physicians remains to be seen, as will the extent to which the reforms can successfully reduce the level of unmet need.
