The successful migration of total joint arthroplasty from the hospital inpatient to outpatient ASC setting

BACKGROUND

This study was undertaken to analyze the clinical results and complication rate of patients undergoing outpatient total joint arthroplasty by a single orthopedic group. All surgeries were performed in the practice-owned ambulatory surgery center (ASC).

METHODS

All patients indicated for outpatient total joint arthroplasty from 2016-2019 with complete pre and post-operative patient reported outcomes were enrolled in the study including hip, knee and partial knee replacements. Patient reported outcomes including HOOS, KOOS and VR-12 were collected at six months. Patient complication and satisfaction data was also collected.

RESULTS

There were 1007 patients enrolled in the study. At six months, THA HOOS and VR-12 scores improved to 82.2 and 54.5/45. TKA KOOS and VR-12 scores improved to an average of 74.3 and 54.0/43.6. At six months, UKA scores improved to an average of 73.6 and 55.1/41.2. All HOOS, KOOS and VR-12 PCS scores improvements were statistically significant (p < 0.001) and met MCID thresholds. A separate cohort of 1898 regionally tracked cases with comprehensive global complication data exhibited 111 complications (unplanned post-operative events generating a medical expense) including manipulation 13 (0.68%), DVT/PE 4 (0.2%), medical 45 (2.4%), wound 8 (0.4%), infection 8 (0.4%). Sixty-six outpatient cases (3.5%) experienced clinical complications requiring some form of additional treatment.

CONCLUSION

Outpatient joint arthroplasty performed in the ASC is safe and effective in appropriately selected patients with complication rates that compares favorably to inpatient procedures.

Case study: Delivery and payment reform in congestive heart failure at two large academic centers

To help support implementation of aligning clinical redesign with payment reforms in practices and institutions throughout the country, we present two cases from Duke University Health System ("Duke") and University of Colorado Hospital ("Colorado"). The studies provide practical solutions for not only implementing clinical redesign, but also an understanding of how those clinical innovations can be aligned with alternative payment models. The cases will explore the following questions: What challenges or problems encouraged the organization to redesign CHF care? How did the organization select and then align care innovations with payment reforms, including bundled payments and shared savings? What did the organization identify as key success factors and/or challenges? How did these changes impact the organization׳s clinical outcomes or financial position? Finally, what lessons would the organization share with others attempting to implement similar strategies?
