Outcomes of an integrated practice unit for vulnerable emergency department patients.

BACKGROUND: An integrated practice unit (IPU) that provides a multidisciplinary approach to patient care, typically involving a primary care provider, registered nurse, social worker, and pharmacist has been shown to reduce healthcare utilization among high-cost super-utilizer (SU) patients or multi-visit patients (MVP). However, less is known about differences in the impact of these interventions on insured vs. uninsured SU patients and super high frequency SUs ([Formula: see text]8 ED visits per 6 months) vs. high frequency SUs (4-7 ED visits per 6 months). METHODS: We assessed the percent reduction in ED visits, ED cost, hospitalizations, hospital days, and hospitalization costs following implementation of an IPU for SUs located in an academic tertiary care facility. We compared outcomes for publicly insured with uninsured patients, and super high frequency SUs with high frequency SUs 6 months before vs. 6 months after enrollment in the IPU. RESULTS: There was an overall 25% reduction in hospitalizations (p < 0.001), and 23% reduction in hospital days (p = 0.0045), when comparing 6 months before vs. 6 months after enrollment in the program. There was a 26% reduction in average total direct hospitalization costs per patient (p = 0.002). Further analysis revealed a greater reduction in health care utilization for uninsured SU patients compared with publicly insured patients. The program reduced hospitalizations for super high frequency SUs. However, there was no statistically significant impact on overall health care utilization of super high frequency SUs when compared with high frequency SUs. CONCLUSIONS: Our study supports existing evidence that dedicated IPUs for SUs can achieve significant reductions in acute care utilization, particularly for uninsured and high frequency SU patients.

Outpatient total knee arthroplasty: is it economically feasible in the hospital setting?

BACKGROUND: With the removal of total knee arthroplasty (TKA) from the Medicare inpatient-only list, outpatient TKA can now be offered, irrespective of payer, in multiple sites. We compared time- and cost-effectiveness of outpatient TKA performed in a hospital outpatient department (HOPD) to that at an inpatient academic medical center (AMC). METHODS: We reviewed all outpatient TKAs performed at our AMC and our HOPD from August 2018 to July 2019. Time efficiency by phase of care was determined, and cost data were obtained from the hospital financial department. Patient selection for outpatient surgery was identical for each site of care. RESULTS: We identified 21 knees that had surgery at the HOPD and 65 knees that had surgery at the AMC. Demographics were similar in both groups. The AMC group had significantly longer in-facility to operating room (Δ (difference) = 33.5 minute, P = .0003), postanesthesia care unit to discharge (Δ = 158.8 minute, P < .0001) and in-facility to discharge (Δ = 199.3 minute, P < .0001) time periods compared to the HOPD group. The HOPD was significantly more cost-effective for the preoperative period (Δ = $75.7, P < .0001), postoperative period (Δ = $315.1, P < .0001), and total cost (Δ = $241, P < .0001). CONCLUSIONS: Outpatient TKAs performed in an HOPD spend significantly less time within the facility than the ones performed in an AMC and cost significantly less. It is expected that approval of Medicare TKAs at ambulatory surgery centers will further improve cost and efficiency.
