Estimating cost implications of potentially avoidable hospitalizations among Oncology Care Model patients with prostate cancer

Impact of a Dedicated Cancer Urgent Care Center on Acute Care Utilization

PURPOSE

Acute care imposes a significant burden on patients and cancer care costs. We examined whether an advanced practice provider-driven, cancer-specific urgent care center embedded within a large tertiary academic center decreased acute care use among oncology patients on active therapy.

MATERIALS AND METHODS

We conducted a quasi-experimental study anchored around the Oncology Extended Care Clinic (OECC) opening date. We evaluated two parallel 4-month periods: a post-OECC period that followed a 5-month run-in phase, and the identical calendar period 1 year earlier. Our primary outcomes included all emergency department (ED) presentations and hospital admissions during the 3-month window following the index provider visit. We used Poisson models to calculate absolute pre-OECC v post-OECC rate differences.

RESULTS

Our cohort included 2,095 patients in the pre-OECC period and 2,188 in the post-OECC period. We identified 32.6 ED visits/100 patients and 41.2 hospitalizations/100 patients in the pre-OECC period, versus 28.2 ED visits/100 patients and 26.1 hospitalizations/100 patients post-OECC. After adjusting for age, sex, race and ethnicity, and practice location, we observed a significant decrease of 4.6 ED visits/100 patients during the post-OECC period (95% CI, -8.92/100 to -0.28/100; P = .04) compared with the pre-OECC period. There was no significant association between the OECC opening and hospitalization rate (rate difference: -3.29 admissions/100 patients; 95% CI, -8.24/100 to 1.67/100; P = .19).

CONCLUSION

Establishing a cancer-specific urgent care center was significantly associated with a modest decrease in emergency room utilization but not with hospitalization rate. Barriers included clinic capacity, patient awareness, and physician comfort with advanced practice provider autonomy. Optimizing workflow and standardizing clinical pathways can create benchmarks useful for value-based payments.
