Models of comprehensive care for older persons with chronic diseases: a systematic review with a focus on effectiveness

Effects of an integrated ambulatory care program on healthcare utilization and costs in older patients with multimorbidity: a propensity score-matched cohort study

BACKGROUND

Population aging has increased the prevalence of multimorbidity, jeopardizing the sustainability and efficiency of healthcare systems. This study aimed to evaluate the effects of an integrated ambulatory care program (IACP) on healthcare utilization and costs among older patients with multimorbidity while accounting for the confounding effects of frailty.

METHODS

A retrospective cohort study using propensity matching including patients aged 65 or older with two or more chronic conditions attending the outpatient clinic at our hospital between June 1 and December 31, 2019, was conducted. Exposure was defined as receipt of IACP care. Patients not undergoing the IACP comprised the unexposed group and were matched at a ratio of 1:4 to patients undergoing the IACP group according to sex, age, Charlson Comorbidity Index score, multimorbidity frailty index score, and number of outpatient visits within 6 months before the index date. Outcomes were changes in healthcare utilization and related costs between 6 months before and after receiving IACP care. Multivariate regression analyses were used for data analysis and the Generalized Estimation Equation method was used to fit the regression models.

RESULTS

A total of 166 (IACP) and 664 (non-exposed) patients were analyzed. The mean participant baseline ages were 77.15 ± 7.77 (IACP) and 77.28 ± 7.90 years (unexposed). In univariate analyses, the IACP group demonstrated greater reductions than the unexposed group in the frequency of outpatient visits (-3.16 vs. -1.36, p < 0.001), number of physicians visited (-0.99 vs. -0.17, p < 0.001), diagnostic fees (-1300 New Taiwan Dollar [NTD] vs. -520 NTD, p < 0.001), drug prescription fees (-250 NTD vs. -70 NTD, p < 0.001), and examination fees (-1620 NTD vs. -700 NTD, p = 0.014). Multivariate analyses demonstrated that patients in the IACP group experienced significant reduction in the frequency of outpatient visits (95% CI: -0.357 to -0.181, p < 0.001), number of physicians visited (95% CI: -0.334 to -0.199, p < 0.001), and overall outpatient costs (95% CI: -0.082 to -0.011, p = 0.01). However, emergency department utilization, hospitalization, and costs did not differ significantly.

CONCLUSIONS

Expanding IACPs may help patients with multimorbidity reduce their use of outpatient clinics at the 6-month follow-up, reduce care fragmentation, and promote sustainability of the healthcare system.

Development, successes, and potential pitfalls of multidisciplinary chronic disease management clinics in a family health team: a qualitative study

BACKGROUND

The creation of Family Health Teams in Ontario was intended to reconfigure primary care services to better meet the needs of an aging population, an increasing proportion of which is affected by frailty and multimorbidity. However, evaluations of family health teams have yielded mixed results.

METHODS

We conducted interviews with 22 health professionals affiliated or working with a well-established family health team in Southwest Ontario to understand how it approached the development of interprofessional chronic disease management programs, including successes and areas for improvement.

RESULTS

Qualitative analysis of the transcripts identified two primary themes: [1] Interprofessional team building and [2] Inadvertent creation of silos. Within the first theme, two subthemes were identified: (a) collegial learning and (b) informal and electronic communication.

CONCLUSION

Emphasis on collegiality among professionals, rather than on more traditional hierarchical relationships and common workspaces, created opportunities for better informal communication and shared learning and hence better care for patients. However, formal communication and process structures are required to optimize the deployment, engagement, and professional development of clinical resources to better support chronic disease management and to avoid internal care fragmentation for more complex patients with clustered chronic conditions.
