A cost-effectiveness analysis after implementation of a fast-track protocol for total knee arthroplasty

Clinical and cost-effectiveness of earlier discharge from acute hospital after total joint arthroplasty

BACKGROUND

Reducing length of stay has been proposed as a key component of policies that aim to meet demand and minimize costs associated with total joint arthroplasty. However, few studies explore shifting of healthcare utilization when length of stay is shortened.

METHODS

This retrospective cohort study examined patients undergoing primary, total hip and knee arthroplasty for osteoarthritis to simulate a policy-level institutional reduction in acute hospital stay by 1 day. Costs, quality of life, and rates of complications, readmission and discharge to inpatient rehabilitation were compared in patients with a three- and four-day length of acute stay. Balance was achieved using overlap-propensity weighting.

RESULTS

In total, 2023 patients were included. Earlier discharge from acute hospital was not associated with a change in odds of 90-day complications (OR: 0.85 [95% CI, 0.58 to 1.27]; P = 0.447), readmissions (OR: 1.11 [95% CI, 0.67 to 1.82]; P = 0.691), and emergency department presentations (OR: 1.07 [95% CI, 0.66 to 1.73]; P = 0.774). Earlier discharge from acute hospital was associated with an increase in odds of discharge to inpatient rehabilitation (OR: 2.16 [95% CI, 1.45 to 3.20]; P < 0.001). No significant differences in costs and quality adjusted life years were observed at one-year. Cost savings during index admission were shifted onto increased costs associated with inpatient rehabilitation.

CONCLUSION

Earlier discharge was not associated with changes in 90-day complications, readmission, or ED presentations. However, an increase in utilization of inpatient rehabilitation was observed, offsetting early cost savings. Patients who were discharged from acute care on day three had no difference in costs compared to those discharged on day four.

The Effects of Motivational Interviews About Activities of Daily Living on Physical Adjustment and Quality of Life in Elderly Total Knee Arthroplasty Patients: A Randomised-Controlled Trial

In old age, knee osteoarthritis is a common disease that reduces mobility. Total knee arthroplasty (TKA) is, in fact, a very important surgery to treat severe knee osteoarthritis. This study aimed to analyse the effect of motivational interviewing (MI) on physical adjustment and quality of life among old patients after TKA. Self-assessment forms were applied before and after the intervention using the functional assessment form and SF-36 Quality of Life Questionnaire in both groups: the intervention group who received MI targeted at daily living activities and the control group who received usual care within a randomised controlled trial that included 70 participants. The results we obtained showed significantly higher functional capacity scores and QOLs among those who underwent MI than those who did not have this additional support, while showing strong adjusted mean differences between two interventions that indicate this effect size difference. There was a notable increase in SF-36 scores from 51.14 to 85.77 which was much higher than the control's rise from 45.97 to 59.46. Therefore, these findings suggest that many elderly people can greatly improve their health status after TKA with MI as it offers an opportunity for effective recovery during the post-operative period, especially among older adults. Therefore, it can be used as an efficient method included in standard routines after operations so that results are improved and patients' satisfaction levels also increased simultaneously too.

Are patients ready for discharge from the hospital after fast-track total knee arthroplasty?-A qualitative study

BACKGROUND

The fast-track based on evidence-based medicine, has dramatically reduced the length of stay for patients undergoing total knee arthroplasty (TKA). Therefore, patients must assume the responsibility for self-functional exercise and care as early as possible. Also, higher standards and expectations of care delivery have been set. Studies into patients' experiences when faced with a discharge decision under a fast-track program are lacking.

OBJECTIVES

(1) Increase the knowledge about patients' experiences of discharged from hospital via a fast-track process after TKA. (2) Explore what gaps exist in the current discharge preparation care service for TKA under fast-track and what can be improved.

METHODS

A qualitative research design was chosen to conduct semi-structured face-to-face interviews with 21 patients from one Chinese hospital who successfully underwent TKA and received discharge orders. Interview data were meticulously analyzed, summarized and thematically distilled using Interpretative Phenomenological Analysis (IPA).

RESULTS

Three themes emerged from the structural analyses: a) Preparing for discharge despite concerns about symptoms-a sense of joy at discharge despite feelings of helplessness, stigmatisation, anxiety about prosthetic function. b) Managing the rehabilitation difficulties-vigilance is needed for medication management, environmental changes, and intimate relationships. c) Creating conditions for safe transition-compassionate bedside manner, listening to patients, and providing a humanized continuing care and referral services are important for safe transitions.

CONCLUSION

Findings suggest that patients undergoing fast-track TKA report good discharge preparation experiences. However, closer analysis reveals difficulties with this process and important directions in which discharge readiness care services can strive.

Simultaneous bilateral TKA in the context of fast track surgery - Do patients meet discharge criteria as anticipated?

BACKGROUND

The efficacy and safety of enhanced recovery after surgery (ERAS) protocols for patients undergoing total knee arthroplasty (TKA) have been generally proven. Previous studies investigating patients undergoing simultaneous bilateral TKA (SBTKA) focused on complications, mortality, and pain and did not examine patients' functional limitations. Therefore, the aim of this study was to investigate to what extent patients undergoing SBTKA are able to meet functional discharge criteria originally designed for their counterparts undergoing unilateral TKA (UTKA) in an ERAS setting.

MATERIALS AND METHODS

All patients who received primary SBTKA between June 2015 and December 2018 were included in this retrospective analysis. For comparison, UTKA patients were matched 1:1 to SBTKA patients using Propensity Score Matching based on age, gender, and BMI. The times to achieving the rehabilitation checkpoints of walking 150 m, walking a flight of stairs, and 90° knee flexion were evaluated.

RESULTS

63 (SBTKA group) and 64 (UTKA group) patients were included. Due to the Propensity-Score-Matching there were no differences regarding age, gender, and BMI. The mean length of stay (LOS) was 9.1 days in the SBTKA and 7.6 days in the UTKA group (p = 0.003). On average, it took SBTKA patients 5.4 days to achieve an uninterrupted walking distance of at least 150 m, while it took UTKA patients 4.1 days (p < 0.001). Mean time to walking a flight of stairs was 6.3 days for SBTKA patients and 4.7 days for UTKA patients (p < 0.001). 90° flexion was achieved after 4.1 days by SBTKA patients and 3.5 days by UTKA patients (p = 0.241).

CONCLUSION

The vast majority of SBTKA patients were able to achieve functional discharge criteria within their inpatient stay when allowed about 30% extra time. Therefore, functional discharge criteria in ERAS protocols designed for UTKA can be considered appropriate for SBTKA patients.

Enhanced recovery after surgery in patients after hip and knee arthroplasty: a systematic review and meta-analysis

PURPOSE

Enhanced recovery after surgery (ERAS) was characterized as patient-centered, evidence-based, multidisciplinary team-developed routes for a surgical speciality and institution to improve postoperative recovery and attenuate the surgical stress response. However, evidence of their effectiveness in osteoarthroplasty remains sparse. This study aimed to develop an ERAS standard and evaluate the significance of ERAS interventions for postoperative outcomes after primary total hip arthroplasty (THA) or total knee arthroplasty (TKA).

METHODS

We searched Medline, Embase, Cochrane databases, and Clinicaltrials.gov for randomized controlled trials, cohort studies, and case-control studies until 24 February 2023. All relevant data were collected from studies meeting the inclusion criteria. Two reviewers independently assessed the risk of bias and extracted data. The primary outcome was the length of stay (LOS), postoperative complications, and readmission rate. The secondary outcomes included transfusion rate, mortality rate, visual analog score (VAS), the Western Ontario and McMaster University Osteoarthritis Index (WOMAC), Short Form 36 (SF-36) bodily pain (SF-36 BP), SF-36 physical function (SF-36 PF), oxford knee score, and range of motion (ROM).

RESULTS

A total of 47 studies involving 76 971 patients (ERAS group: 29 702, control group: 47 269) met the inclusion criteria and were included in the meta-analysis. The result showed that ERAS could significantly shorten the LOS (WMD = -2.65, P < .001), reduce transfusion rate (OR = 0.40, P < .001), and lower 30-day postoperative mortality (OR = 0.46, P = .01) without increasing postoperative complications or readmission rate. Apart from that, ERAS may decrease patients' VAS (WMD = -0.88, P = .01) while improving their ROM (WMD = 6.65, P = .004), SF-36 BP (WMD = 4.49, P < .001), and SF-36 PF (WMD = 3.64, P < .001) scores. However, there was no significant difference in WOMAC, oxford knee score between the ERAS and control groups.Furthermore, we determined that the following seven components of the ERAS program are highly advised: avoid bowel preparation, PONV prophylaxis, standardized anesthesia, use of local anesthetics for infiltration analgesia and nerve blocks, tranexamic acid, prevent hypothermia, and early mobilization.

CONCLUSION

Our meta-analysis suggested that the ERAS could significantly shorten the LOS, reduce transfusion rate, and lower 30-day postoperative mortality without increasing postoperative complications or readmission rate after THA and TKA. Meanwhile, ERAS could decrease the VAS of patients while improving their ROM, SF-36 BP, and SF-36 PF scores. Finally, we expect future studies to utilize the seven ERAS elements proposed in our meta-analysis to prevent increased readmission rate for patients with THA or TKA.

Enhanced Recovery after Total Joint Arthroplasty (TJA): A Contemporary Systematic Review of Clinical Outcomes and Usage of Key Elements

BACKGROUND

Enhanced recovery after surgery (ERAS) is a pathway designed to improve the care of surgical patients and achieve early recovery. The clinical outcomes and usage of key elements of ERAS pathways in total joint arthroplasty (TJA) need further reanalysis. This article aims to provide an overview of the latest clinical outcomes and current usage of key elements of ERAS pathways in TJA.

METHODS

We undertook a systematic review of the PubMed, OVID, and EMBASE databases in February 2022. Studies investigating the clinical outcomes and usage of key elements of ERAS in TJA were included. The components of successful ERAS programs and their usage were further determined and discussed.

RESULTS

Twenty-four studies involving 216,708 patients assessed ERAS pathways for TJA. A total of 95.8% (23/24) of studies reported a reduced length of stay (LOS), followed by reduce overall opioid consumption or pain (87.5% [7/8]), save costs (85.7% [6/7]), improvements in patient-reported outcomes or functional recovery (60% [6/10]), and reduced incidence of complications (50% [5/10]). In addition, preoperative patient education (79.2% [19/24]), anesthetic protocol (54.2% [13/24]), use of local anesthetics for infiltration analgesia or nerve blocks (79.2% [19/24]), perioperative oral analgesia (66.7% [16/24]), perioperative surgical factors including reduced use of tourniquets and drains (41.7% [10/24]), use of tranexamic acid (41.7% [10/24]) and early mobilization (100% [24/24]) were contemporary comparatively "active" components of ERAS.

CONCLUSIONS

ERAS for TJA has favorable clinical outcomes in terms of reducing LOS and overall pain, saving costs, accelerating functional recovery, and reducing complications, although the evidence is still low in quality. In the current clinical scenario, only some "active" components of the ERAS program are widely used.

Outcome measures in total hip arthroplasty: have our metrics changed over 15 years?

INTRODUCTION

Consensus has not been reached regarding ideal outcome measures for total hip arthroplasty (THA) clinical evaluation and research. The goal of this review was to analyze the trends in outcome metrics within the THA literature and to discuss the potential impact of instrument heterogeneity on clinical practice.

MATERIALS AND METHODS

A PubMed search of all manuscripts related to THA from January 2005 to December 2019 was performed. Statistical and linear regression analyses were performed for individual outcome metrics as a proportion of total THA publications over time.

RESULTS

There was a statistically significant increase in studies utilizing outcomes metrics between 2005 and 2019 (15.1-29.5%; P < 0.001; R² = 98.1%). Within the joint-specific subcategory, use of the Harris Hip Score (HHS) significantly decreased from 2005 to 2019 (82.8-57.3%; P < 0.001), use of the Hip Disability and Osteoarthritis Outcome Score (HOOS) significantly increased (0-6.7%; P < 0.001), and the modified HHS significantly increased (0-10.5%; P < 0.001). In the quality of life subcategory, EQ-5D demonstrated a significant increase in usage (0-34.8%; P < 0.001), while Short Form-36 significantly decreased (100% vs. 27.3%; P = 0.008).

CONCLUSIONS

The utilization of outcome-reporting metrics in THA has continued to increase, resulting in added complexity within the literature. The utilization rates of individual instruments have shifted over the past 15 years. Additional study is required to determine which specific instruments are recommended.

Key Components, Current Practice and Clinical Outcomes of ERAS Programs in Patients Undergoing Orthopedic Surgery: A Systematic Review

Enhanced recovery after surgery (ERAS) protocols have led to improvements in outcomes in several surgical fields, through multimodal optimization of patient pathways, reductions in complications, improved patient experiences and reductions in the length of stay. However, their use has not been uniformly recognized in all orthopedic fields, and there is still no consensus on the best implementation process. Here, we evaluated pre-, peri-, and post-operative key elements and clinical evidence of ERAS protocols, measurements, and associated outcomes in patients undergoing different orthopedic surgical procedures. A systematic literature search on PubMed, Scopus, and Web of Science Core Collection databases was conducted to identify clinical studies, from 2012 to 2022. Out of the 1154 studies retrieved, 174 (25 on spine surgery, 4 on thorax surgery, 2 on elbow surgery and 143 on hip and/or knee surgery) were considered eligible for this review. Results showed that ERAS protocols improve the recovery from orthopedic surgery, decreasing the length of hospital stays (LOS) and the readmission rates. Comparative studies between ERAS and non-ERAS protocols also showed improvement in patient pain scores, satisfaction, and range of motion. Although ERAS protocols in orthopedic surgery are safe and effective, future studies focusing on specific ERAS elements, in particular for elbow, thorax and spine, are mandatory to optimize the protocols.

Implementation of a rapid recovery protocol in total knee arthroplasty. A randomized controlled trial

BACKGROUND

Rapid recovery (RP) in total knee arthroplasty may increase the functionality while reducing costs. The aim of this study is to prove the benefits of a rapid recovery program compared to our classic protocol.

PATIENTS AND METHODS

We performed a RCT (NCT03823573) in patients undergoing otal knee arthroplasty. Intervention group (RP protocol) received local infiltration of levo-bupivacaine in the periarticular tissue and supervized ambulation 4-6h after surgery. Control (C) group received a femoral nerve block with levo-bupivacaine, while a drain was used. Ambulation after its removal. All the patients completed an Oxford Knee Score prior to surgery and 6 months after discharge. An ecodoppler to assess the presence of deep vein thrombosis was made one month after discharge. Minimum follow-up was of 6 months.

RESULTS

A total of 175 patients were included in the trial (92 patients in the control group, 83 patients in the RP group). There were no differences in sex, age, implanted prosthesis, hemoglobin drop, need for transfusion, range of motion on discharge (C: 82.6°, RP: 85°) and at the end of the follow-up (C: 105.1, RP: 106.6), Oxford Knee Score improvement (C: 17.5 points; RP: 19.3 points), patient satisfaction or re-admissions at the emergency department (C: 7.6%; RP: 10.8%). Significancy was found on time of ischemia (C: 81.29min; RP: 85.35min; P=0.03), need for morphine shots (C: 19.7%; RP: 38.6%; P=0.007), hospital stay (C: 3.84 days; RP: 2.54 days, P<0.0001) and time until ambulation (C: 2.46 days; RP: 0.23 days; P<0.0001).

CONCLUSION

Rapid recovery protocols can reduce hospital stay without increasing complications or need for re-admission.

Health related quality of life in patients having total knee replacement and associations with symptoms, recovery, and patient education: A six month follow up study

AIM

To describe the symptoms, recovery, patient education, and health related quality of life (HRQOL) of patients having total knee replacements at three time points and to detect experiences and situations that predict HRQOL six weeks and six months post-surgery.

METHOD

A prospective exploratory two-site study assessing 123 patients, while in hospital (T1), at six weeks (T2), and at six months (T3) post-discharge. HRQOL was measured using the SF-36v2 and symptoms were measured with the Hospital and Anxiety Scale. Two questions considered pain and two considered movement and tiredness while two questions addressed recovery and patient education. Linear regression models were used to calculate predictors of mental and physical HRQOL at T2 and T3.

RESULTS

HRQOL improved from T1 to T3. The main predictors of higher physical scores at T2 were; being older, fewer symptoms of depression and little distress related to movement. At T3 the main predictors were; having resumed work, finding patient education very useful, experiencing no pain in the last 24 h and fewer symptoms of depression. The main predictors of higher mental scores at T2 were fewer symptoms of anxiety and depression and little distress related to movement while at T3 these were fewer symptoms of anxiety and depression and experiencing no pain last 24 h.

CONCLUSION

Apart from pain, function and resumption of activities, the symptoms of anxiety and depression influence HRQOL. These symptoms should be assessed during the hospital stay.

Returning to orthopaedic business as usual after COVID-19: strategies and options

PURPOSE

The aim of this manuscript is to review the available strategies in the international literature to efficiently and safely return to both normal orthopaedic surgical activities and to normal outpatient clinical activities in the aftermath of a large epidemic or pandemic. This information would be beneficial to adequately reorganize outpatient clinics and hospitals to provide the highest possible level of orthopaedic care to our patients in a safe and efficient manner.

METHODS

A literature search was performed for relevant research articles. In addition, the World Health Organisation (WHO), the US Centers for Disease Control (CDC), American Association of Orthopaedic Surgeons (AAOS), the EU CDC and other government health agency websites were searched for any relevant information. In particular, interest was paid to strategies and advise on managing the orthopaedic patient flow during outpatient clinics as well as surgical procedures including the necessary safety measures, while still providing a high-quality patient experience. The obtained information is provided as a narrative review.

RESULTS

There was not any specific literature concerning the organization of an outpatient clinic and surgical activities and the particular challenges in dealing with a high-volume practice, in the afterwave of a pandemic.

CONCLUSION

As the COVID-19 crisis has abruptly halted most of the orthopaedic activities both in the outpatient clinic and the operating room, a progressive start-up scenario needs to be planned. The exact timing largely depends on factors outside of our control. After restrictions will be lifted, clinical and surgical volume will progressively increase. This paper offers key points and possible strategies to provide the highest level of safety to both the orthopaedic patient and the orthopaedic team including administrative staff and nurses, during the start-up phase.
