Improved clinical outcomes of outpatient enhanced recovery hip and knee replacements in comparison to standard inpatient procedures: A study of patients who experienced both.

BACKGROUND: The benefits of combining enhanced recovery after surgery (ERAS) interventions with an outpatient program for total hip/knee arthroplasty (THA/TKA) are uncertain. This study's main objective was to evaluate adverse events with an ERAS-outpatient compared to standard-inpatient care and secondary objectives were to compare pain, functional recovery, PROMs and satisfaction. HYPOTHESIS: The ERAS-outpatient program would result in reduced adverse events compared to standard-inpatient care. METHODS: An ambidirectional single subject cohort study was conducted on 48 consecutive patients who experienced both a standard-inpatient and an ERAS-outpatient THA/TKA (contralaterally). Adverse event rate according to the Clavien-Dindo scale, the Comprehensive Complications Index (CCI) and the number of unplanned episodes of care were assessed. Postoperative pain on a numeric rating scale, opioid consumption in morphine milligram equivalents, functional recovery, patient reported outcome measures (PROMs) (WOMAC, KOOS, HOOS, Forgotten Joint Score and Patient Joint Perception) and patients' satisfaction were also evaluated. RESULTS: Following the ERAS-outpatient surgery, complication rates were reduced by more than 50% (2.1 vs. 4.4, p<0.001), CCI was significantly lower (12.3 vs. 19.1, p<0.001), and similar unplanned episodes of care were observed (p>0.999). In the first 8 postoperative hours, perceived pain was similar (p>0.805) while opioid consumption was significantly reduced (9.3 vs. 26.5, p<0.001). Patients walked, climbed stairs, showered, performed activities of daily living, practised sports, went back to work sooner (p<0.001), but PROMs were similar between groups at the last follow-up (p>0.188). Patients were more satisfied of the ERAS-outpatient pathway and recommended it significantly more (p<0.002). CONCLUSION: Compared to the conventional inpatient care, the ERAS-outpatient program proved to be safer, enable faster functional recovery, and improve patients' satisfaction which highlight the importance of following ERAS principles when implementing an outpatient THA/TKA program.

Combining enhanced recovery and short-stay protocols for hip and knee joint replacements: the ideal solution.

Pressure to reduce health care costs, limited hospital bed availability as well as improvements in surgical techniques and perioperative care motivated many health care centres to implement short-stay protocols for patients undergoing hip or knee arthroplasty. To improve patient outcomes and maintain care safety, we strongly believe the best way to implement a successful outpatient program would be to embrace the principles of Enhanced Recovery After Surgery (ERAS), and to improve patient recovery to a level such that the patient could leave the hospital sooner. Enhanced Recovery Canada and the Canadian Patient Safety Institute support the development of ERAS pathways for orthopedic procedures. The goal is to provide patients, health care providers and leaders with helpful tools and resources to effectively implement and sustain ERAS protocols. Reducing the rate of adverse events while reducing the length of hospital stays to less than 24 hours is a winning situation for everyone.

Enhanced recovery short-stay hip and knee joint replacement program improves patients outcomes while reducing hospital costs.

INTRODUCTION: An attractive option to reduce hospital length of stay (LOS) after hip or knee joint replacement (THA, TKA) is to follow the Enhanced Recovery After Surgery principles (ERAS) to improve patient experience to a level where they will feel confident to leave for home earlier. The objective of this study was to evaluate the implementation of short-stay protocol following the ERAS principles. HYPOTHESIS: We hypothesized that our ERAS THA and TKA short-stay protocol would result in a lower complication rate, shorter hospital LOS and reduced direct health care costs compared to our standard procedure. MATERIAL AND METHODS: We compared the complications rated according to Clavien-Dindo scale, hospital LOS and costs of the episode of care between a prospective cohort of 120 ERAS short-stay THA or TKA and a matched historical control group of 150 THA or TKA. RESULTS: Significantly lower rate of Grade 1 and 2 complications in the ERAS short-stay group compared with the standard group (mean 0.8 vs 3.0, p<0.001). No difference was found between the 2 groups for Grade 3, 4, or 5 complications. The mean hospital LOS for the ERAS short-stay group decreased by 2.8 days for the THAs (0.1 vs 2.9 days, p<0.001) and 3.9 days for the TKAs (1.0 vs 4.9 days, p<0.001). The mean estimated direct health care costs reduction with the ERAS short-stay protocol was 1489 CAD per THA and 4158 CAD per TKA. DISCUSSION: In many short-stay protocols, focus has shifted from ERAS goals of a reduction in complications and improved recuperation to use length of stay as the main factor of success. Implementation of an ERAS short-stay protocol for patients undergoing THA or TKA at our institution resulted not only in reduced hospital LOS, but also in improved patient care and reduced direct health care costs.
