Orthopaedic registries with patient-reported outcome measures

Use of patient-reported outcome measures (PROMs) by orthopedic surgeons in Saudi Arabia

BACKGROUND

There is increasing literature on the usefulness of patient-reported outcome measures (PROMs), but far fewer studies to determine their use by orthopedic surgeons and the barriers they face in applying PROMs in their daily clinical activity.

METHODS

Cross-sectional study using a questionnaire that was distributed in both soft and hard copy formats to a sample of 262 orthopedic surgeons. Participants included orthopedic surgeons who are employed by the Ministry of Health (MOH) in Riyadh and the Eastern Province, Saudi Arabia. The questionnaire was distributed through on-site visitations to orthopedic departments in MOH hospitals as well as through online correspondence by email, WhatsApp, and social media.

RESULTS

The study sample included 262 orthopedic surgeons (13.7% females and 86.3% males). Surgeons aged < 34, 35-44, and 45-54 years old represented 28.66%, 38.9%, and 20.2% of the study sample, respectively. The majority of the included surgeons did not use PROMs (69.1%), and some (17.2%) used it for research purposes. Only 5% used it regularly in daily clinical work.

CONCLUSION

The clinical use of PROMs among orthopedic surgeons was negligible, even though an overwhelming majority were interested in using PROMs. The reasons provided included a lack of knowledge on how to use PROMs and the perception that it is too time-consuming to add to regular clinical routine. There should be more efforts towards training surgeons on how to use PROMs, whereas increasing compatibility with existing software tools used by MOH hospitals may help offset time-related reservations.

Patient-reported outcome measures (PROMs) following knee arthroplasty: a prospective cohort study protocol

INTRODUCTION

To evaluate the quality of clinical practice, patient-reported outcome measures (PROMs) are important as certain questions could only be answered by the patient himself. PROMs help to get a better understanding what is meaningful to a patient and directly affects daily functioning. To move beyond traditional measures, we are interested in what matters to patients and developed this project. The aim of this article is to provide the protocol for our study collecting PROMs in daily medical practice from patients who undergo knee arthroplasty.

METHODS AND ANALYSIS

This study is a single-site, observational, prospective cohort study. We will recruit patients scheduled for a knee arthroplasty in our medical office, situated in a private clinic. After signed informed consent, patients complete self-reported questionnaires before the surgery, after 4 months, 1 year, 2 years, 3 years, 4 years and 5 years. We will use the following PROMs: Knee injury and Osteoarthritis Outcome Score, Forgotten Joint Score, EuroQol five dimensions and satisfaction. Additionally, the surgeon will complete the objective Knee Society Score. Administration of the questionnaires will be electronically or paper-based. We will assess differences between preoperative and postoperative data with paired t-test for continuous variables and Wilcoxon signed-rank test for categorical variables. To assess subgroup differences, we will use unpaired t-test for continuous variables and Mann-Whitney U test for categorical variables. To assess possible presence of bias, we will conduct sensitivity analyses.

ETHICS AND DISSEMINATION

The study has been reviewed and approved by the local ethics committee in Basel, Switzerland. Written informed consent will be obtained from all patients. We will disseminate the results of the study through peer-reviewed journals, national and international conference presentations and presentations to relevant stakeholders through appropriate channels.

What is the minimum response rate on patient-reported outcome measures needed to adequately evaluate total hip arthroplasties?

Background

Unknown is which response rate on patient-reported outcome measures (PROMs) is needed to both obtain an accurate outcome and ensure generalizability in evaluating total hip arthroplasty (THA) procedures. Without an evidence based minimum response rate (MRR) on THA PROMs, it is possible that hospitals report invalid patient-reported outcomes (PROs) due to a too low response rate. Alternatively, hospitals may invest too much in achieving an unnecessary high response rate. The aim of this study is to gain an insight into the MRR on PROMs needed to adequately evaluate THA procedures from a clinical perspective.

Methods

Retrospective study on prospective collected data of primary, elective THA procedures was performed. MRR was investigated for each PROM (NRS pain at rest, NRS pain during activity, EQ-5D-3L, HOOS-PS, anchor function, OHS, anchor pain and NRS satisfaction) separately to calculate the primary outcome: MRR for the THA PROMs set. MRR on a PROM needed to have (condition 1.) similar PRO change score (3 month score minus preoperative score) including confidence interval, (condition 2.) maintaining the influence of each change score predictor and (condition 3.) equal distribution of each predictor, as those of a 100% PROM response rate group. Per PROM, a 100%-group was identified with all patients having the PRO change score. Randomly assessed groups of 90% till 10% response rate (in total 90 groups) were compared with the 100%-group. Linear mixed model analyses and linear regressions were executed.

Results

The MRR for the THA PROMs set was 100% (range: 70–100% per PROM). The first condition resulted in a MRR of 60%, the second condition in a MRR of 100% and the third condition in a MRR of 10%.

Conclusions

A 100% response rate on PROMs is needed in order to adequately evaluate THA procedures from a clinical perspective. All stakeholders using THA PROs should be aware that 100% of the THA patients should respond on both preoperative and 3 month postoperative PROMs. For now, taking the first step in improving evaluation of THA for quality control by achieving at least two of the three conditions of MRR, advised is to require a response rate on PROMs of 60% as the lower limit.

Evolving Outcome Measures in Total Knee Arthroplasty: Trends and Utilization Rates Over the Past 15 Years

BACKGROUND

Patient-reported outcome metrics and reporting are important for demonstrating value associated with total knee arthroplasty (TKA). This review studied the patient-reported outcome utilization trends as reported within the TKA literature over a 15-year period.

METHODS

A PubMed search of all manuscripts related to TKA from January 2005 to December 2019 was performed. Descriptive statistics were used for individual outcome metrics as proportions of total article publications focusing on TKA outcomes. Linear regressions analysis was performed to demonstrate significant changes in utilization rates over time.

RESULTS

There was a significant overall increase in studies utilizing outcome metrics between 2005 and 2019 (16.1%-45.0%; P < .001; R² = 98.7%). Within joint-specific metrics (2005-2019), use of Knee Disability and Osteoarthritis Outcome score increased (0%-14.8%; P < .001); while use of Knee Society Knee Scoring System decreased (55.2%-35.4%; P = .007). Of the studies reporting general health, use of the Forgotten Joint Score-12 decreased (100%-66.7% from 2014 to 2019; P = .006), and Patient-Reported Outcome Measurement Information System Global-10 increased (0%-21.4% from 2005 to 2019; P < .001). In the quality of life subcategory (2005-2019), EuroQol 5-Dimension Health Outcome Survey increased in usage (14.3%-28.0%; P < .001), while Short Form-36 use decreased (85.7%-36.6%; P < .001).

CONCLUSION

Although utilization of outcome metrics has significantly increased over the last 15 years in the TKA literature, there still exists considerable heterogeneity of outcome metrics. This lack of consensus may impede comparisons of studies for clinical and research purposes, as well as hinder cross-walk of outcome tools over time. Further study is needed to identify ideal global and joint-specific tools, while balancing issues like ease of use and utility in specific populations such as the young and highly active.

Patient-Reported Outcome Measures (Pain, Function, and Quality of Life) After Aseptic Revision Total Knee Arthroplasty

BACKGROUND

Despite the growing frequency of revision total knee arthroplasty (rTKA), there is limited information regarding patient-reported outcome measures (PROMs) after that procedure. Therefore, the purpose of this study was to determine (1) PROM improvements in pain, function, quality of life (QOL), and global health and (2) predictors of PROMs for patients undergoing aseptic rTKA as determined using a multilevel model with patients nested within surgeons.

METHODS

A prospective cohort of 246 patients who underwent aseptic rTKA from January 2016 to December 2017 and had baseline and 1-year postoperative PROMs were analyzed. The most common surgical indications were aseptic loosening (n = 109), instability (n = 73), and implant failure (n = 64). The PROMs included in this study were the Knee injury and Osteoarthritis Outcome Score (KOOS)-Pain, -Physical Function Short Form (PS), and -Quality of Life (QOL) as well as the Veterans Rand-12 (VR-12) Physical Component Summary (PCS) and Mental Component Summary (MCS). Multivariable linear regression models with patients nested within surgeons were constructed for predicting change in PROMs from baseline to 1 year.

RESULTS

The mean 1-year postoperative improvements in the KOOS-Pain and PS PROMs were 30.3 and 19.15 points, respectively, for the overall rTKA series. Improvement in the KOOS-Pain was associated with older age, baseline arthrofibrosis, lower baseline pain, and non-Medicare/Medicaid insurance and worsening of the scores was associated with multiple prior surgical procedures and instability. Improvement in the KOOS-PS was associated with baseline arthrofibrosis and female sex and worsening was associated with limited baseline function, an instability diagnosis, multiple prior surgical procedures, and increased hospital length of stay (LOS). Overall, the mean KOOS-QOL improved by 29.7 points. Although the mean VR-12 PCS improved, 54.9% of the patients saw no clinical improvement. Additionally, only 31.3% of the patients reported improvements in the VR-12 MCS. A multilevel mixed-effects model with patients/operations nested within surgeons demonstrated that the differences in the surgeons' results were minimal and explained only ∼1.86%, ∼1.12%, and ∼1.65% of the KOOS-Pain, KOOS-PS, and KOOS-QOL variance that was not explained by other predictors, respectively.

CONCLUSIONS

Overall, patients undergoing aseptic rTKA had improvements in pain, function, and QOL PROMs at 1 year. Although overall QOL improved, other global-health PROMs remained unchanged. The associations highlighted in this study can help guide the preoperative clinical decision-making process by setting expectations before aseptic rTKA.

Patient-Reported Outcomes Following Total Knee Replacement in Patients <65 Years of Age-A Systematic Review and Meta-Analysis

An increasing number of total knee replacements (TKRs) are being performed in response to the growing burden of osteoarthritis. Patients <65 years of age represent the fastest growing group of TKR recipients and are expected to account for an increasing number of primary and revision procedures. Concerns have been raised about the outcomes that can be expected by this age demographic who are more active, physically demanding, and have longer life expectancies compared to older TKR recipients. This systematic review and meta-analysis evaluated the effectiveness of TKR for osteoarthritis in patients <65 years of age, compared to older individuals. A systematic search of Embase and Medline was conducted to identify studies which examined patient-reported outcomes measured using disease-specific and generic health-related quality of life instruments. Ten studies met our inclusion criteria and were included in this review. These studies comprised 1747 TKRs performed between 1977 and 2014. In the meta-analysis of two prospective studies (288 TKRs), patients <65 years of age were able to attain large and clinically meaningful improvements in pain, function, and quality of life. One of these studies (61 TKRs) suggested that patients <55 years of age attained a larger degree of improvement compared to older individuals. Results into the second postoperative decade were less certain, with some data suggesting a high prevalence of pain and patterns of functional decline. Further research is required to investigate longer-term outcomes following TKR for osteoarthritis in younger patients.

Clinical outcomes of kinematic alignment versus mechanical alignment in total knee arthroplasty: a systematic review

Although mechanical alignment (MA) has traditionally been considered the gold standard, the optimal alignment strategy for total knee arthroplasty (TKA) is still debated.

Kinematic alignment (KA) aims to restore native alignment by respecting the three axes of rotation of the knee and thereby producing knee motion more akin to the native knee.

Designer surgeon case series and case control studies have demonstrated excellent subjective and objective clinical outcomes as well as survivorship for KA TKA with up to 10 years follow up, but these results have not been reproduced in high-quality randomized clinical trials.

Gait analyses have demonstrated differences in parameters such as knee adduction, extension and external rotation moments, the relevance of which needs further evaluation.

Objective improvements in soft tissue balance using KA have not been shown to result in improvements in patient-reported outcomes measures.

Technologies that permit accurate reproduction of implant positioning and objective measurement of soft tissue balance, such as robotic-assisted TKA and compartmental pressure sensors, may play an important role in improving our understanding of the optimum alignment strategy and implant position.

Cross-Cultural Adaptation and Validation of the Romanian Marx Activity Rating Scale for Anterior Cruciate Ligament Reconstruction

AIM

We aimed to translate, cross-cultural adapt and validate the Marx activity rating scale (MARS) of the knee for Romanian patients with anterior cruciate ligament (ACL) injury.

METHOD

The original English form was translated according to guidelines. We included patients with ACL injury undergoing reconstruction in two centers over 3 years. Subjects completed the translated MARS, International Knee Documentation Committee (IKDC) subjective knee form and EuroQol EQ5D. The examining physician completed the Tegner Lysholm scale as an objective evaluation. Re-testing was obtained after one month. We used Spearman`s correlation to evaluate construct validity and reproducibility, Cronbach's alpha for internal consistency and intraclass correlation for test-retest reliability.

RESULTS

We collected valid forms from 99 patients (32.1 ± 8.8 years, 64.6% males) during the preoperative evaluation and 45 were re-tested. Significant, very good correlations were found between the MARS and Tegner Lysholm (Spearman's r = 0.712, p < 0.0001) and IKDC (Spearman's r = 0.801, p < 0.0001). Cronbach's alpha was 0.893 at the initial completion and 0.799 at re-test. The intraclass correlation coefficient was 0.895.

CONCLUSIONS

The Romanian-translated MARS is a valid, consistent and reliable physical activity outcome measure in patients with anterior cruciate ligament reconstruction.

[Documentation of self-reported patient outcomes in trauma surgery : Clinical benefits of patient reported outcome measures]

The future progressive aspiration of evidence-based medicine makes it necessary to carry out a comprehensive documentation of functional treatment after trauma surgery. Especially the subjective, patient-centered satisfaction with treatment results will be the focus of attention. Patient centered outcome measures (PROM) are potent instruments to capture the patients' functional status validly and in a cost and time-efficient manner. Additionally, modern technical options have the potential to evaluate specific joint function even better. Parameters, such as range of motion can soon be measured by the patient using the widely spread smartphone technology.

Development and early findings of a semiautomated arthroplasty registry in a multi-institutional healthcare network

AIMS

The primary aim of this paper was to outline the processes involved in building the Partners Arthroplasty Registry (PAR), established in April 2016 to capture baseline and outcome data for patients undergoing arthroplasty in a regional healthcare system. A secondary aim was to determine the quality of PAR's data. A tertiary aim was to report preliminary findings from the registry and contributions to quality improvement initiatives and research up to March 2019.

METHODS

Structured Query Language was used to obtain data relating to patients who underwent total hip or knee arthroplasty (THA and TKA) from the hospital network's electronic medical record (EMR) system to be included in the PAR. Data were stored in a secure database and visualized in dashboards. Quality assurance of PAR data was performed by review of the medical records. Capture rate was determined by comparing two months of PAR data with operating room schedules. Linear and binary logistic regression models were constructed to determine if length of stay (LOS), discharge to a care home, and readmission rates improved between 2016 and 2019.

RESULTS

The PAR captured 16,163 THAs and TKAs between April 2016 and March 2019, performed in seven hospitals by 110 surgeons. Manual comparison to operating schedules showed a 100% capture rate. Review of the records was performed for 2,603 random operations; 2,298 (88.3%) had complete and accurate data. The PAR provided the data for three abstracts presented at international conferences and has led to preoperative mental health treatment as a quality improvement initiative in the participating institutions. For primary THA and TKA surgeries, the LOS decreased significantly (p < 0.001) and the rate of home discharge increased significantly (p < 0.001) between 2016 and 2019. Readmission rates did not correlated with the date of surgery (p = 0.953).

CONCLUSION

The PAR has high rates of coverage (the number of patients treated within the Partners healthcare network) and data completion and can be used for both research purposes and quality improvement. The same method of creating a registry that was used in the PAR can be applied to hospitals using similar EMR systems. Cite this article: Bone Joint J 2020;102-B(7 Supple B):90-98.

Do Medicare's Patient-Reported Outcome Measures Collection Windows Accurately Reflect Academic Clinical Practice?

BACKGROUND

The Comprehensive Care for Joint Replacement (CJR) mandates collection of patient-reported outcome measures (PROMs) for eligible total hip and total knee arthroplasty (THA and TKA) procedures during specific time periods that may not be attainable within routine academic practice.

METHODS

We performed a retrospective analysis of prospectively collected PROM data from a 2017 cohort of primary THA and TKA patients who completed the Patient-Reported Outcomes Measurement Information System-10 global health survey in preoperative or postoperative time periods. The primary outcome was completion rates of Patient-Reported Outcomes Measurement Information System-10 per the CJR collection periods (90-0 days preoperative and 270-365 days postoperative) compared to an extended postoperative collection period of 270-396 days. Bivariate analysis and logistic regression were used to analyze the association between survey completion rates and patient characteristics.

RESULTS

Of the 860 primary THAs and TKAs in 2017, 725 (84.3%) had preoperative surveys completed 90-0 days before surgery. Among the 725 patients, 215 (29.7%) completed postoperative surveys within the CJR timeline of 270-365 days. Completion increased by 120 additional surveys (+16.5%) in the additional postoperative time period of 270-396 days (P < .001). No patient or procedural factors significantly correlated with a higher likelihood of postoperative PROM completion (P > .05 for all covariates).

CONCLUSION

In an academic clinical practice, completion rates of postoperative PROMs as part of routine clinical practice within the CJR mandated period was low for THA and TKA patients. CJR may consider additional time beyond 365 days to improve PROM completion rates.

Cross-cultural adaptation and validation of the Romanian knee disability and osteoarthritis outcome score for joint replacement (KOOSJR)

Aim

To perform validation of the Romanian Knee disability and Osteoarthritis Outcome Score for Joint Replacement (KOOSJR).

Method

Ninety-six patients (101 knees) with advanced osteoarthritis (OA) scheduled for total knee replacement completed Romanian translations of KOOSJR and IKDC (International Knee Documentation Committee – subjective knee form) and Euroqol EQ-5D-5 L, and the treating physician completed the original knee society score (KSS).

Results

Average age was 66.4 (range 50–83) years and male to female ratio 1:3.76. There was moderate correlation between the test-retest (average 4 days) KOOSJR (r = 0.618, n = 45) and IKDC (r = − 0.671, n = 99), weak between KOOSJR and EQ-5D-5 L Index (r = − 0.431, n = 100) and VAS (r = − 0.364, n = 99) and very weak to KSS score (r = − 0.133, n = 98) and function (r = − 0.072, n = 97) For the first KOOSJR, Cronbach’s alpha was 0.816 and intraclass correlation coefficient (ICC) 0.816 (95% CI 0.755–0.866) for average measures. For the retest, Cronbach’s alpha was 0.841 (95% CI 0.760–0.903) for averages.

Conclusion

The Romanian Knee disability and Osteoarthritis Outcome Score for Joint Replacement (KOOSJR) is a valid, reliable, consistent and reproducible clinical score for patients with OA requiring arthroplasty.
