Barriers for the referral to outpatient cardiac rehabilitation: A predictive model including actual and perceived risk factors and perceived control

Predictors of referral behaviour and intention amongst physicians in a medical consortium based on the theory of planned behaviour: a cross-sectional study in China

Introduction

To promote patients' referral across healthcare institutions and integrated care delivery, we identified predictors of physicians' behaviour and intention to refer patients in a county medical consortium in China on the basis of the theory of planned behaviour (TPB).

Methods

This census-based cross-sectional study was conducted in Yangxi Hospital Group (YHG). All physicians in county hospitals and township health centres were invited to participate. Structural equation modelling was employed to analyse the relationships between referral intention and behaviour and other TPB variables in the group of whole participants and in sub-groups.

Results

In total, 330 physicians participated in this study. One-third of participants were general practitioners, and half of them were from county hospitals. Referral behaviour of females (χ2 = 20.372, p < 0.001), who had lower education levels (χ2 = 17.859, p = 0.001), lower professional title (χ2 = 14.963, p = 0.005), and lower monthly salary (χ2 = 33.753, p < 0.001) were less frequent than the others. Among them, 116 (35.2%), 108 (32.7%), and 106 (32.1%) respondents reported that they had never referred patients, had referred patients 1-9 times, and had referred patients over 10 times during the past 3 months, respectively. The mean score of referral intention was 4.23/5 (SD = 0.71). In the model with all participants, a stronger referral intention (β = 0.218, 95% CI = 0.080-0.356) was associated with more frequent referral behaviour. The subjective norm (β = 0.703, 95% CI = 0.590-0.817) was the strongest predictor of physicians' referral intention, followed by perceived behavioural control (β = 0.234, 95% CI = 0.090-0.378). Mediated by referral intention, subjective norms (β = 0.153, p < 0.01) and perceived behavioural control (β = 0.190, p < 0.01) had significant indirect effects on physicians' referral behaviour. The model with participants in county hospitals showed similar results to the model with all participants. Meanwhile, in the model with participants in township health centres, there were no significant associations between referral behaviour and other TPB constructs.

Conclusion

Physicians' referral behaviour was influenced by intention, subjective norms, and perceived behavioural control in Chinese county hospitals.

Disparities in Geographic Access to Cardiac Rehabilitation in Los Angeles County

Background Exercise-based cardiac rehabilitation (CR) is known to reduce morbidity and mortality for patients with cardiac conditions. Sociodemographic disparities in accessing CR persist and could be related to the distance between where patients live and where CR facilities are located. Our objective is to determine the association between sociodemographic characteristics and geographic proximity to CR facilities. Methods and Results We identified actively operating CR facilities across Los Angeles County and used multivariable Poisson regression to examine the association between sociodemographic characteristics of residential proximity to the nearest CR facility. We also calculated the proportion of residents per area lacking geographic proximity to CR facilities across sociodemographic characteristics, from which we calculated prevalence ratios. We found that racial and ethnic minorities, compared with non-Hispanic White individuals, more frequently live ≥5 miles from a CR facility. The greatest geographic disparity was seen for non-Hispanic Black individuals, with a 2.73 (95% CI, 2.66-2.79) prevalence ratio of living at least 5 miles from a CR facility. Notably, the municipal region with the largest proportion of census tracts comprising mostly non-White residents (those identifying as Hispanic or a race other than White), with median annual household income <$60 000, contained no CR facilities despite ranking among the county's highest in population density. Conclusions Racial, ethnic, and socioeconomic characteristics are significantly associated with lack of geographic proximity to a CR facility. Interventions targeting geographic as well as nongeographic factors may be needed to reduce disparities in access to exercise-based CR programs. Such interventions could increase the potential of CR to benefit patients at high risk for developing adverse cardiovascular outcomes.

Trends in cardiac rehabilitation enrollment post-coronary artery bypass grafting upon implementation of automatic referral in Southeast Asia: A retrospective cohort study

Introduction: Cardiac rehabilitation (CR) is an effective but underutilized intervention. Strategies have been identified to increase its use, but there is paucity of data testing them in low-resource settings. We sought to determine the effect of automatic referral post-coronary artery bypass graft (CABG) surgery on CR enrollment.

Methods: This is a retrospective cohort study assessing cardiac patients referred to CR at a tertiary center in Southeast Asia from 2013 to 2019. The paper-based pathway was introduced at the end of 2012. The checklist with automatic CR referral on the third day post-operation prompted a nurse to educate the patient about CR, initiate phase 1 and encourage enrollment in phase 2. Patients who were not eligible for the pathway for administrative or clinical reasons were referred at the discretion of the attending physician (i.e., usual care). Enrollment was defined as attendance at≥1 CR visit.

Results: Of 4792 patients referred during the study period, 394 enrolled in CR. Significantly more patients referred automatically enrolled compared to usual care (225 [11.8%] vs. 169 [5.8%]; OR=2.2, 95% CI=1.8-2.7), with increases up to 23.4% enrollment in 2014 (vs. average enrollment rate of 5.9% under usual referral). Patients who enrolled following automatic referral were significantly younger and more often employed (both P<0.001); no other differences were observed.

Conclusion: In a lower-resource, Southeast Asian setting, automatic CR referral is associated with over two times greater enrollment in phase 2 CR, although efforts to maintain this effect are required.

Enrollment and Adherence to Early Outpatient and Maintenance Cardiac Rehabilitation Programs

Early outpatient (ECR) and maintenance cardiac rehabilitation (MCR) programs are essential, evidence-based services that have received unequivocal endorsement by national and international professional organizations. However, the latest data characterizing ECR enrollment and adherence fell well short of what would be expected for a therapy that has accumulated decades of empirical evidence touting the associated physiologic, physical, psychosocial, and financial benefits. Although national participation levels have remained stagnant, a series of recent publications showcase effective strategies that could bolster both ECR enrollment and adherence levels at the institutional level. Unlike ECR, fewer reports on enrollment and adherence rates exist for MCR, partly due to the lack of standardization of this service. In this review, we aim to highlight current data on enrollment and adherence to ECR and MCR and discuss evidence-based programmatic strategies to support utilization of both services.

Increasing Cardiac Rehabilitation Participation Through a "Nearer to Home" Patient Referral Program

PURPOSE

Time to travel to cardiac rehabilitation (CR) centers is a barrier to participation, and tertiary referral centers often care for patients living at a substantial distance. We sought to determine the impact of referring eligible patients to CR centers closer to home or workplace on overall participation rate.

METHODS

An observational review was conducted in patients from a large cardiovascular program who were referred to CR (January 1, 2015, through December 31, 2016). Those declining participation due to distance from their home were identified and provided coordinated referral to a CR program they chose near their home or workplace.

RESULTS

Of the 2912 patients referred to CR, 673 (23%) participated and 1900 declined due to distance. Contact was made in 2017 with 1237 of the 1900 of whom 1083 recalled a discussion of distance referral and completed the phone survey. Participants mean age was 64 yr, predominantly White (88%), male (65%), married (66%), and 70% had ≥ comorbidity. Out of the 1083 referred to a local CR program, 78% reported attending. Of those who attended CR, 55% (469/849) would not have attended had they not been referred to a program closer to their home or workplace. Overall participation increased from 23% to >50% of those referred from our institution.

CONCLUSIONS

Coordinating CR referrals from the discharging facility to facilities closer to home or workplace is an effective means for increasing participation. The very low-cost effort has the potential to have a very meaningful impact on the long-term outcome of cardiovascular patients.

Relevant problems of participation and education of patients in cardiac rehabilitation and secondary prevention programs

The review discusses the participation of patients with coronary artery disease after acute myocardial infarction and revascularization surgeries in cardiac rehabilitation (CR) and secondary prevention programs. The problems of patients not being included in rehabilitation programs and the reasons for low adherence to these programs are considered. The contribution of non-drug therapy to achievement of CR and secondary prevention goals is discussed. Various strategies are proposed for involving and increasing adherence of patients to CR programs.
