Delivering person-centered care in individuals with knee osteoarthritis (OA) necessitates consideration of other chronic conditions that frequently co-occur. We sought to understand the extent to ...which arthritis therapists consider type 2 diabetes mellitus (T2DM) when treating persons with knee OA and concomitant T2DM, and barriers to doing so.
We conducted 18 semistructured telephone interviews with arthritis therapists working within a provincially funded arthritis care program (Arthritis Society Canada) in Ontario, Canada. We first analyzed interviews deductively using the Theoretical Domains Framework (TDF) to comprehensively identify barriers and enablers to health behaviors. Then, within TDF domains, we inductively developed themes.
We identified 5 TDF domains as prominently influencing the behavior of arthritis therapists considering concomitant T2DM when developing a knee OA management plan. These were as follows: therapists' perceived lack of specific knowledge around comorbidities including diabetes; the lack of breadth in skills in behavioral change techniques to help patients set and reach their goals, particularly when it came to physical activity; variable intention to factor a patient's comorbidity profile to influence their treatment recommendations; the perception of their professional role and identity as joint focused; and the environmental context with lack of formalized follow-up structure of the current Arthritis Society Canada program that limited sufficient patient monitoring and follow-up.
Within the context of a Canadian arthritis program, we identified several barriers to arthritis therapists considering T2DM in their management plan for persons with knee OA and T2DM. These results can help inform strategies to improve person-centered OA care and overall health outcomes.
Evidence on sex differences in the association between obstructive sleep apnea (OSA) and cardiovascular outcomes is limited and controversial. We conducted a historical cohort study to investigate ...this relationship.
Clinical data on adults who underwent sleep study at a large urban academic hospital (Toronto, Canada) between 1994 and 2010 were linked to provincial health administrative data from 1991 to 2015. We fit Cox regressions to investigate the association between OSA severity and a cardiovascular composite outcome (all-cause mortality or hospitalization due to myocardial infarction, stroke, heart failure or atrial fibrillation), controlling for risk factors and stratifying by sex.
A total of 10,149 subjects were included: median age of 49 years, 38% women. Over a median of 9.3 years, 1782 (18%) participants developed an outcome. The association between percentage of sleep time spent with oxygen saturation <90% and outcome was stronger for women (HR for IQR, 3 vs 0% = 1.30, 1.19–1.42) than for men (HR for IQR = 1.13, 1.06–1.21) (p for interaction = 0.01) in the adjusted model. Stratifying by sex, oxygen desaturations and heart rate in sleep were significant predictors in both men and women, while presence of daytime sleepiness, sleep efficiency and periodic leg movements in sleep were predictive in women but not in men.
In a large clinical cohort with suspected OSA, the impact of OSA as measured by the degree of nocturnal oxygen desaturation on the composite outcome was found to be greater in women than in men. We also found a different predictive ability of OSA-related factors by sex.
•Sleep apnea induced nocturnal hypoxemia in women was associated with acute cardiac events.•The association of nocturnal hypoxemia and cardiac events was greater in women than in men.•Sleepiness, poor sleep and leg movements in sleep were predictors in women but not in men.
The most rapidly growing population of patients undergoing total knee arthroplasty (TKA) is under the age of 65. The objective of our study was to gain insight into the factors influencing ...physicians' recommendations for persons in this age group with moderate osteoarthritis (OA).
Rheumatologists and orthopedic surgeons attending national meetings were asked to complete a survey including a standardized scenario of a 62-year-old person with knee OA who has moderate knee pain limiting strenuous activity despite medical management. We used an experimental 2 × 2 × 2 design to examine the effects of sex, employment status, and severity of radiographic OA on physicians' recommendations. Each physician was asked to rate a single scenario.
The percentage of physicians recommending TKA varied from 30% to 55% for scenarios describing a patient with mild radiographic OA, and from 39% to 71% for scenarios describing a patient with moderate radiographic OA. Surgeons were less likely to recommend TKA for women compared to men of the same age, employment status, symptom severity, and functional status, and radiographs. Rheumatologists practicing in academic settings were more likely to recommend TKA compared to those practicing in nonacademic settings, and American surgeons were more likely to recommend TKA compared to their European counterparts.
Orthopedic surgeons and rheumatologists vary significantly in their recommendations for patients with moderate knee pain and functional limitations. Both patient and physician characteristics influence physicians' recommendations, and rheumatologists and orthopedic surgeons display different patterns of decision making.
Background
Rates of use of total joint arthroplasty among appropriate and willing candidates are lower in women than in men. A number of factors may explain this gender disparity, including patients’ ...preferences for surgery, gender bias influencing physicians’ clinical decision-making, and the patient-physician interaction.
Questions/purposes
We propose a framework of how patient gender affects the patient and physician decision-making process of referral and recommendation for total joint arthroplasty and consider potential interventions to close the gender gap in total joint arthroplasty utilization.
Methods
The process involved in the referral and recommendation for total joint arthroplasty involves eight discrete steps. A systematic review is used to describe the influence of patient gender and related clinical and nonclinical factors at each step.
Where are we now?
Patient gender plays an important role in the process of referral and recommendation for total joint arthroplasty. Female gender primarily affects Steps 3 through 8, suggesting barriers unique to women exist in the patient-physician interaction.
Where do we need to go?
Developing and evaluating interventions that improve the quality of the patient-physician interaction should be the focus of future research.
How do we get there?
Potential interventions include using decision support tools that facilitate shared decision-making between patients and their physicians and promoting cultural competency and shared decision-making skills programs as a core component of medical education. Increasing physicians’ acceptance and awareness of the unconscious biases that may be influencing their clinical decision-making may require additional skills programs.
Hospital readmissions are common and costly, and no single intervention or bundle of interventions has reliably reduced readmissions. Virtual wards, which use elements of hospital care in the ...community, have the potential to reduce readmissions, but have not yet been rigorously evaluated.
To determine whether a virtual ward-a model of care that uses some of the systems of a hospital ward to provide interprofessional care for community-dwelling patients-can reduce the risk of readmission in patients at high risk of readmission or death when being discharged from hospital.
High-risk adult hospital discharge patients in Toronto were randomly assigned to either the virtual ward or usual care. A total of 1923 patients were randomized during the course of the study: 960 to the usual care group and 963 to the virtual ward group. The first patient was enrolled on June 29, 2010, and follow-up was completed on June 2, 2014.
Patients assigned to the virtual ward received care coordination plus direct care provision (via a combination of telephone, home visits, or clinic visits) from an interprofessional team for several weeks after hospital discharge. The interprofessional team met daily at a central site to design and implement individualized management plans. Patients assigned to usual care typically received a typed, structured discharge summary, prescription for new medications if indicated, counseling from the resident physician, arrangements for home care as needed, and recommendations, appointments, or both for follow-up care with physicians as indicated.
The primary outcome was a composite of hospital readmission or death within 30 days of discharge. Secondary outcomes included nursing home admission and emergency department visits, each of the components of the primary outcome at 30 days, as well as each of the outcomes (including the composite primary outcome) at 90 days, 6 months, and 1 year.
There were no statistically significant between-group differences in the primary or secondary outcomes at 30 or 90 days, 6 months, or 1 year. The primary outcome occurred in 203 of 959 (21.2%) of the virtual ward patients and 235 of 956 (24.6%) of the usual care patients (absolute difference, 3.4%; 95% CI, -0.3% to 7.2%; P = .09). There were no statistically significant interactions to indicate that the virtual ward model of care was more or less effective in any of the prespecified subgroups.
In a diverse group of high-risk patients being discharged from the hospital, we found no statistically significant effect of a virtual ward model of care on readmissions or death at either 30 days or 90 days, 6 months, or 1 year after hospital discharge.

Ensuring a representative workforce is a matter of equity and social justice and has implications for patient care and population health. We examined the relationship of the binary gender identity ...and race of physicians who felt comfortable to self-identify, with workplace experiences and career satisfaction in academic medicine.
The outcome of interest of a cross-sectional survey of full-time clinical faculty members within the Department of Medicine, University of Toronto, was physician's self-reported career satisfaction. Using logistic regression, we examined relationships of binary gender identity (female/male) and race under-represented minority (URM) versus over-represented in medicine (ORM) to: workplace experiences (respectful interactions, perception of having to work harder, exclusion from social networks, witnessing/experiencing unprofessionalism, and confidence in taking action to address incivility without reprisal); and career satisfaction, controlling for age, rank, protected time, and workplace experiences.
Female gender and URM status were associated with younger age, lower rank, and less positive workplace experiences. 132 respondents (44.4%) strongly agreed they had career satisfaction. Compared with ORM men, career satisfaction was significantly lower for URM and ORM female physicians (OR 0.30, 95% CI 0.14-0.65, and 0.48, 95% CI 0.27-0.85, respectively) and non-significantly lower for URM male physicians (OR 0.62, 95% CI 0.32-1.19). Adjustment for academic rank and workplace experiences fully attenuated these relationships.
URM female academic physicians had lower career satisfaction than their ORM male counterparts, largely explained by systematic differences in workplace experiences, particularly perceptions of exclusion from social networks and having to work harder to be perceived as legitimate scholars. This suggests a role for institutions and leaders to build inclusive, anti-racist, and anti-oppressive cultures to support the flourishing of all faculty.
The underuse of total joint arthroplasty in appropriate candidates is more than 3 times greater among women than among men. When surveyed, physicians report that the patient's sex has no effect on ...their decision-making; however, what occurs in clinical practice may be different. The purpose of our study was to determine whether patients' sex affects physicians' decisions to refer a patient for, or to perform, total knee arthroplasty.
Seventy-one physicians (38 family physicians and 33 orthopedic surgeons) in Ontario performed blinded assessments of 2 standardized patients (1 man and 1 woman) with moderate knee osteoarthritis who differed only by sex. The standardized patients recorded the physicians' final recommendations about total knee arthroplasty. Four surgeons did not consent to the inclusion of their data. After detecting an overall main effect, we tested for an interaction with physician type (family physician v. orthopedic surgeon). We used a binary logistic regression analysis with a generalized estimating equation approach to assess the effect of patients' sex on physicians' recommendations for total knee arthroplasty.
In total, 42% of physicians recommended total knee arthroplasty to the male but not the female standardized patient, and 8% of physicians recommended total knee arthroplasty to the female but not the male standardized patient (odds ratio OR 4.2, 95% confidence interval CI 2.4-7.3, p < 0.001; risk ratio RR 2.1, 95% CI 1.5-2.8, p < 0.001). The odds of an orthopedic surgeon recommending total knee arthroplasty to a male patient was 22 times (95% CI 6.4-76.0, p < 0.001) that for a female patient. The odds of a family physician recommending total knee arthroplasty to a male patient was 2 times (95% CI 1.04-4.71, p = 0.04) that for a female patient.
Physicians were more likely to recommend total knee arthroplasty to a male patient than to a female patient, suggesting that gender bias may contribute to the sex-based disparity in the rates of use of total knee arthroplasty.
Improving value in musculoskeletal health care has emerged as an important objective in both the United States and Canada. In order to achieve this objective, providers need to have a clear ...definition of value and an infrastructure for measuring outcomes of interest to patients and costs over the episode of care. Although national patient registries have been established in the United States and Canada, they nevertheless lag behind other registries worldwide in terms of collecting patient-reported outcomes and capturing data from a wide cross-section of hospitals and physicians. With the help of professional medical societies and the creation of national initiatives, patient-reported outcomes data collection on a large scale may be possible, but many challenges remain regarding implementation. Alternatives to the fee-for-service payment model, including pay-for-reporting and pay-for-performance, may help incentivize physicians and health-care providers to obtain and improve on patient-reported outcomes data collection. Other payment reforms, such as bundled payments, have been piloted in certain regions, but their sustainability and long-term success are unclear at this time. Novel health-care delivery strategies aimed at improving quality, coordinating multispecialty care, and enhancing patient participation in shared decision-making have shown promise in improving patient-centered outcomes, but delivery models continue to vary greatly throughout the United States and Canada. The current status of musculoskeletal health-care delivery requires substantial change before the goal of improving patient outcomes and lowering health-care costs can be achieved.
ObjectivesOne-fifth of total knee arthroplasty (TKA) recipients experience a suboptimal outcome. Incorporation of patients’ preferences in TKA assessment may improve outcomes. We determined the ...discriminant ability of preoperative measures of TKA need, readiness/willingness and expectations for a good TKA outcome.MethodsIn patients with knee osteoarthritis (OA) undergoing primary TKA, we preoperatively assessed TKA need (Western Ontario-McMaster Universities OA Index (WOMAC) Pain Score and Knee injury and Osteoarthritis Outcome Score (KOOS) function, arthritis coping), health status, readiness (Patient Acceptable Symptom State, depressive symptoms), willingness (definitely yes—yes/no) and expectations (outcomes deemed ‘very important’). A good outcome was defined as symptom improvement (met Outcome Measures in Rheumatology and Osteoarthritis Research Society International (OMERACT–OARSI) responder criteria) and satisfaction with results 1 year post TKA. Using logistic regression, we assessed independent outcome predictors, model discrimination (area under the receiver operating characteristic curve, AUC) and the predicted probability of a good outcome for different need, readiness/willingness and expectations scenarios.ResultsOf 1,053 TKA recipients (mean age 66.9 years (SD 8.8); 58.6% women), 78.1% achieved a good outcome. With TKA need alone (WOMAC pain subscale, KOOS physical function short-form), model discrimination was good (AUC 0.67, 95% CI 0.63 to 0.71). Inclusion of readiness/willingness, depressive symptoms and expectations regarding kneeling, stair climbing, well-being and performing recreational activities improved discrimination (p=0.01; optimism corrected AUC 0.70, 0.66–0.74). The predicted probability of a good outcome ranged from 44.4% (33.9–55.5) to 92.4% (88.4–95.1) depending on level of TKA need, readiness/willingness, depressive symptoms and surgical expectations.ConclusionsAlthough external validation is required, our findings suggest that incorporation of patients’ TKA readiness, willingness and expectations in TKA decision-making may improve the proportion of recipients that experience a good outcome.
