Optimising perioperative care for hip and knee arthroplasty in South Africa: a Delphi consensus study

Cost-Effective Healthcare in Rehabilitation: Physiotherapy for Total Endoprosthesis Surgeries from Prehabilitation to Function Restoration

Knee and hip joint replacements for the elderly are increasingly placing a burden on healthcare. Our aim was to verify the efficiency of the prehabilitation program among patients with knee arthroplasty (TKA) and hip arthroplasty (THA), taking into account the length and cost of postoperative rehabilitation and the restoration of function. We introduced a two-week preoperative physiotherapy program for patients awaiting knee and hip replacement surgery. We measured the duration and costs of the hospital stays, the active and passive range of motion of the hip and knee joints, and the quality of life. In the study, 99 patients participated (31 male, 68 female), with a mean age of 69.44 ± 9.69 years. We showed that, as a result of the prehabilitation program, the length of postoperative hospital stay decreased (THA: median 31.5 (IQR 26.5-32.5) vs. median 28 (IQR 21-28.5), TKA: median 36.5 (IQR 28-42) vs. median 29 (IQR 26-32.5)), and the patients' quality of life showed a significant improvement (TKA: median 30.5 (IQR 30-35) vs. median 35 (IQR 33-35), THA: median 25 (IQR 25-30) vs. median 33 (IQR 31.5-35)). The flexion movements were significantly improved through prehabilitation in both groups. Based on our positive results, we recommend the introduction of prehabilitation into TKA- and THA-related care.

Content and delivery of pre-operative interventions for patients undergoing total knee replacement: a rapid review

BACKGROUND

Total knee replacement (TKR) is a common operation typically performed for end-stage knee osteoarthritis. Patients awaiting TKR often have poor health-related quality of life. Approximately 20% of patients experience persistent pain post-TKR. Pre-operative TKR interventions could improve pre- and post-operative outcomes, but future research is required to inform their design. This review aimed to identify and synthesize recent literature on the content and delivery of pre-operative TKR interventions to help guide future research and clinical practice.

METHODS

This rapid review included randomized trials of pre-operative TKR interventions ("outcomes studies") and primary studies exploring patients' and/or health professionals' views of pre-operative TKR interventions ("views studies"). Medline, Embase, PsycINFO, CINAHL and the Cochrane Central Register of Controlled Trials were searched for English language studies published between January 2009 and December 2020. Eligible studies' reference lists were screened. Studies were appraised using the Mixed Methods Appraisal Tool. The findings were narratively synthesized using a convergent segregated approach.

RESULTS

From 3263 records identified, 52 studies were included (29 outcomes studies, 21 views studies, two outcomes/views studies). The studies' methodological quality varied but was generally highest in qualitative studies. The outcomes studies investigated education (n=5), exercise (n=20), psychological (n=2), lifestyle (n=1), and/or other interventions (n=5). The views studies addressed education (n=20), exercise (n=3), psychological (n=1), lifestyle (n=4), and/or other interventions (n=1). Only three outcomes studies (two randomized controlled trials (RCTs) and a pilot study) compared the effectiveness of intervention components/delivery approaches. The two RCTs' results suggest that pre-operative TKR exercise interventions are equally effective regardless of whether they include strength or strength plus balance training and whether they are hospital- or home-based. Personal tailoring and using more than one delivery format were associated with improved outcomes and/or perceived as beneficial for multiple intervention types.

CONCLUSIONS

Definitive evidence on the optimal design of pre-operative TKR interventions is lacking. Personal tailoring and employing multiple delivery formats appear to be valuable design elements. Preliminary evidence suggests that including balance training and hospital versus home delivery may not be critical design elements for pre-operative TKR exercise interventions.

Same-day discharge after early mobilisation and increased frequency of physiotherapy following hip and knee arthroplasty

Background

Advanced rehabilitation pathway (ARP) after hip and knee arthroplasties is popular globally and is gaining ground in South Africa (SA). A multidisciplinary team in Rustenburg, SA, has implemented an ARP with the first same-day discharge (SDD) from hospital. The lack of evidence of physiotherapy protocols within an ARP determined our study.

Objectives

Determine and compare hospital length of stay (LOS) (hours), patient satisfaction (Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)), patient safety (30-day re-admission) and cost between the two cohorts.

Method

A quantitative prospective patient (treatment) group receiving early mobilisation with increased frequency of physiotherapy on post-operative day zero (POD0) was compared to a conservatively managed retrospective historical (control) group following post-operative elective hip and knee arthroplasties.

Results

Results for the prospective group which were significantly improved relative to the retrospective group included decreased LOS (median 7.650, p < 0.001), less pain at 6 weeks (mean 16.20, standard deviation [SD] = 2.673, p < 0.001), less stiffness (mean 5.82, SD = 1.214, p = 0.007), higher function (mean 54.87, SD = 8.544, p < 0.001), lower hospital cost (mean R43 340, p < 0.001) and physiotherapy cost (mean R1069, p < 0.001), and total costs compared to the retrospective group (mean R117 062, p < 0.001).

Conclusion

Safe and cost-effective SDD is possible in an ARP with earlier mobilisation and increased frequency of physiotherapy on POD0.

Clinical implications

Achieving safe SDD after hip and knee arthroplasty surgeries saved costs and improved patient satisfaction, with a decrease in LOS being beneficial for medical funders and stakeholders including government aiming to implement National Health Insurance (NHI) in the future.

Physiotherapy in an advanced rehabilitation pathway for patients after hip and knee arthroplasty: A proposal

Background

Accelerated rehabilitation pathway (ARP) decrease patients’ hospital length of stay (LOS). A lack of evidence exists on physiotherapy management and outcome as part of ARP in South Africa (SA). Our study will aim to determine whether early mobilisation and increased frequency of physiotherapy treatments for participants after hip or knee arthroplasty surgery on post-operative day 0 (POD 0) affect outcome.

Methods/design

A quantitative prospective cohort study incorporating ARP on (n = 60) non-randomised elective hip and knee arthroplasty participants will be compared with a more conservatively managed historical control group (n = 60). The physiotherapy protocol includes early mobilisation and exercises 1–3 h post-operatively on POD 0 and a second mobilisation and exercise session, 1–2 h later. Outcomes measures are as follows: hours for LOS, the WOMAC measured pre-operatively, 6 weeks and 3 months post-operatively, 30-day readmission for safety and cost comparison between the prospective and historical cohorts. Descriptive statistics will be undertaken. A paired t-test will be used to analyse each of the outcome measures across the time periods if data are normally distributed. Length of stay, WOMAC score and cost data will be compared between the groups, using a Mann–Whitney U test. The occurrence of adverse events will be compared between the groups using Pearson’s chi-square tests. The confidence interval will be set at 95% and p = 0.05 will be considered statistically significant.

Discussion

Globally, ARP’s are successfully implemented to manage patients presenting with hip and knee osteoarthritis (OA). Research investigating physiotherapy protocols in an ARP is lacking in the literature.

Conclusion

Achieving the same-day discharge after hip and knee arthroplasty surgeries may help elective surgery backlogs and waiting lists in a more cost-effective manner.

Clinical implications

The same day discharge after arthroplasty may be a cost-effective management option in the future.

Consensus on pre-operative total knee replacement education and prehabilitation recommendations: a UK-based modified Delphi study

BACKGROUND

Over 90,000 total knee replacement (TKR) procedures are performed annually in the United Kingdom (UK). Patients awaiting TKR face long delays whilst enduring severe pain and functional limitations. Almost 20% of patients who undergo TKR are not satisfied post-operatively. Optimising pre-operative TKR education and prehabilitation could help improve patient outcomes pre- and post-operatively; however, current pre-operative TKR care varies widely. Definitive evidence on the optimal content and delivery of pre-operative TKR care is lacking. This study aimed to develop evidence- and consensus-based recommendations on pre-operative TKR education and prehabilitation.

METHODS

A UK-based, three-round, online modified Delphi study was conducted with a 60-member expert panel. All panellists had experience of TKR services as patients (n = 30) or professionals (n = 30). Round 1 included initial recommendations developed from a mixed methods rapid review. Panellists rated the importance of each item on a five-point Likert scale. Panellists could also suggest additional items in Round 1. Rounds 2 and 3 included all items from Round 1, new items suggested in Round 1 and charts summarising panellists' importance ratings from the preceding round. Free-text responses were analysed using content analysis. Quantitative data were analysed descriptively. All items rated as 'Important' or 'Very important' by at least 70% of all respondents in Round 3 were included in the final set of recommendations.

RESULTS

Fifty-five panellists (92%) (patients n = 26; professionals n = 29) completed Round 3. Eighty-six recommendation items were included in Round 1. Fifteen new items were added in Round 2. Rounds 2 and 3 therefore included 101 items. Seventy-seven of these reached consensus in Round 3. Six items reached consensus amongst patient or professional panellists only in Round 3. The final set of recommendations comprises 34 education topics, 18 education delivery approaches, 10 exercise types, 13 exercise delivery approaches and two other treatments.

CONCLUSIONS

This modified Delphi study developed a comprehensive set of recommendations that represent a useful resource for guiding decision-making on the content and delivery of pre-operative TKR education and prehabilitation. The recommendations will need to be interpreted and reviewed periodically in light of emerging evidence.

Quality of recovery after total hip and knee arthroplasty in South Africa: a national prospective observational cohort study

Background

Encouraged by the widespread adoption of enhanced recovery protocols (ERPs) for elective total hip and knee arthroplasty (THA/TKA) in high-income countries, our nationwide multidisciplinary research group first performed a Delphi study to establish the framework for a unified ERP for THA/TKA in South Africa. The objectives of this second phase of changing practice were to document quality of patient recovery, record patient characteristics and audit standard perioperative practice.

Methods

From May to December 2018, nine South African public hospitals conducted a 10-week prospective observational study of patients undergoing THA/TKA. The primary outcome was ‘days alive and at home up to 30 days after surgery’ (DAH₃₀) as a patient-centred measure of quality of recovery incorporating early death, hospital length of stay (LOS), discharge destination and readmission during the first 30 days after surgery. Preoperative patient characteristics and perioperative care were documented to audit practice.

Results

Twenty-one (10.1%) out of 207 enrolled patients had their surgery cancelled or postponed resulting in 186 study patients. No fatalities were recorded, median LOS was 4 (inter-quartile-range (IQR), 3–5) days and 30-day readmission rate was 3.8%, leading to a median DAH₃₀ of 26 (25–27) days. Forty patients (21.5%) had pre-existing anaemia and 24 (12.9%) were morbidly obese. In the preoperative period, standard care involved assessment in an optimisation clinic, multidisciplinary education and full-body antiseptic wash for 67 (36.2%), 74 (40.0%) and 55 (30.1%) patients, respectively. On the first postoperative day, out-of-bed mobilisation was achieved by 69 (38.1%) patients while multimodal analgesic regimens (paracetamol and Non-Steroid-Anti-Inflammatory-Drugs) were administered to 29 patients (16.0%).

Conclusion

Quality of recovery measured by a median DAH₃₀ of 26 days justifies performance of THA/TKA in South African public hospitals. That said, perioperative practice, including optimisation of modifiable risk factors, lacked standardisation suggesting that quality of patient care and postoperative recovery may improve with implementation of ERP principles. Notwithstanding the limited resources available, we anticipate that a change of practice for THA/TKA is feasible if ‘buy-in’ from the involved multidisciplinary units is obtained in the next phase of our nationwide ERP initiative.

Development of a Personalized m/eHealth Algorithm for the Resumption of Activities of Daily Life Including Work and Sport after Total and Unicompartmental Knee Arthroplasty: A Multidisciplinary Delphi Study

Evidence for recommendations concerning the resumption of activities of daily life, including work and sport, after knee arthroplasty is lacking. Therefore, recommendations vary considerably between hospitals and healthcare professionals. We aimed to obtain multidisciplinary consensus for such recommendations. Using a Delphi procedure, we strived to reach consensus among a multidisciplinary expert panel of six orthopaedic surgeons, three physical therapists, five occupational physicians and one physician assistant on recommendations regarding the resumption of 27 activities of daily life. The Delphi procedure involved three online questionnaire rounds and one face-to-face consensus meeting. In each of these four rounds, experts independently decided at what time daily life activities could feasibly and safely be resumed after knee arthroplasty. We distinguished patients with a fast, average and slow recovery. After four Delphi rounds, the expert panel reached consensus for all 27 activities. For example, experts agreed that total knee arthroplasty patients with a fast recovery could resume cycling six weeks after the surgery, while those with an average and slow recovery could resume this activity after nine and twelve weeks, respectively. The consensus recommendations will subsequently be integrated into an algorithm of a personalized m/eHealth portal to enhance recovery among knee arthroplasty patients.
