Lessons learned from the hip and knee musculoskeletal outcomes data evaluation and management system

Predictors of survey non-response two years after hip arthroscopy: Results from an institutional prospective registry

Purpose

Survey-based studies are inherently subject to non-response bias. A comprehensive understanding of the factors contributing to non-response is important for minimizing attrition bias and ensuring generalizability of results. The purpose of this study was to determine the preoperative factors associated with survey non-response 2 years after hip arthroscopy.

Methods

Patients undergoing hip arthroscopy at a single center between October 2015 and March 2020 were approached for enrollment in a prospective registry. Patients were emailed an electronic survey at baseline and at 1 and 2 years postoperatively. The primary outcome was response to the 2-year postoperative survey. Patients who failed to complete any part of the 2-year postoperative survey after a series of standardized email, text message, and phone call reminders were considered non-responders. Baseline sociodemographics and patient-reported outcomes (PROs) were compared between the groups using Pearson Chi-Squared or Wilcoxon Rank-Sum tests. Logistic regression was used to identify predictors of non-response.

Results

Ninty-nine patients were enrolled and completed the baseline survey. There were 25 non-responders (25 %) at 2 years. Non-responders demonstrated a higher proportion of patients who were male, identified as non-white, and did not respond to the 1-year postoperative survey. There were no differences in baseline PROs between responders and non-responders. When controlling for age and sex, patients who did not identify as white (OR = 4.3, 95 % CI [1.3, 14.4]) and patients who did not respond to the 1-year postoperative survey (OR = 4.5, 95 % CI [1.5, 13.8]) were more likely to be non-responders at 2 years.

Conclusion

Not responding to 1 year postoperative survey and non-white race are independent predictors of non-response at 2 years after hip arthroscopy. Baseline PROs do not differ between responders and non-responders.

Combining preoperative expectations and postoperative met expectations to predict patient-reported outcomes after knee surgery

Introduction

Both preoperative expectations and postoperative met expectations can independently influence patient-reported outcomes (PROs), however, their combined effect on PROs is not well understood. This study aimed to determine the prognostic significance of categorizing non-arthroplasty knee surgery patients into clusters based on both preoperative expectations and postoperative met expectations.

Methods

638 patients who underwent non-arthroplasty knee surgery from June 2015 to May 2021 at a single academic institution were analyzed. Patients were grouped based on both preoperative expectations and two-year postoperative met expectations scores using cluster analysis. Four distinct expectations cluster groups were formed: high preoperative-high met expectations (HIGH-HIGH), low preoperative-high met expectations (LOW-HIGH), high preoperative-low met expectations (HIGH-LOW), and low preoperative-low met expectations (LOW-LOW). Socioeconomic data and PROs were compared based on cluster group, and logistic regression was performed to determine the likelihood of achieving a patient-perceived "completely better" status based on cluster group.

Results

Patients with high met expectations, regardless of preoperative expectations, reported better two-year PROs compared to patients with low met expectations. Patients with high preoperative expectations achieved better outcomes only when those expectations were met postoperatively. Low preoperative expectations did not preclude patients from achieving good outcomes, as long as those expectations were met. The HIGH-HIGH group had increased odds of achieving completely better status compared to the LOW-HIGH group (OR = 1.68, p = .02), HIGH-LOW group (OR = 16.69, p < .001), and LOW-LOW group (OR = 5.17, p < .001). The HIGH-LOW group had decreased odds of achieving completely better status compared to the LOW-LOW group (OR = .31, p = .01).

Conclusion

Met expectations may be a stronger predictor of postoperative outcomes than preoperative expectations in non-arthroplasty knee surgery. This study highlights the importance of setting realistic preoperative expectations and focusing on achieving expectations postoperatively. These findings offer valuable insights for clinicians to manage patient expectations effectively based on individual characteristics and expected treatment outcomes.

Higher preoperative patient expectations predict better patient-reported psychosocial health outcomes after hip arthroscopy

Introduction

Preoperative expectations are a determinant of patient-reported outcomes (PROs) within several orthopaedic subspecialties. However, the impact on outcomes after hip arthroscopy is unclear. The aim of this study was to explore the relationship between preoperative patient expectations and PROs after hip arthroscopy.

Methods

Patients who underwent hip arthroscopy at a single institution were included. Patient expectations were measured preoperatively using the Musculoskeletal Outcomes Data Evaluation and Management System (MODEMS) expectations domain. Patient-Reported Outcomes Measurement Information System (PROMIS) domains, a numeric pain scale (NPS), and the Marx activity rating scale (MARS) were assessed 2 years postoperatively. Spearman's coefficient was used to assess the correlation between preoperative expectations and 2-year PROs. Linear regression was used to ascertain the effect of preoperative expectations on 2-year PROs.

Results

105 patients were included, and 78 (74 %) completed 2-year follow-up. The mean (SD) preoperative expectations score was 88.3 (15.3). Higher expectations correlated with better postoperative fatigue, anxiety, depression, pain, and activity levels, as well as more improvement in fatigue, pain, and activity. Expectations scores were higher for patients who achieved minimal clinically important difference (MCID) for PROMIS Fatigue (92.6 vs 82.0, p = .003) and MARS activity (95.3 vs 86.2, p = .014). When controlling for possible confounders, higher expectations independently predicted better postoperative PROMIS Fatigue (β = -0.26, SE = 7.23), Social Satisfaction (β = 0.24, SE = 0.09), and Anxiety (β = -0.24, SE = 0.08).

Conclusion

Higher preoperative expectations are an independent predictor of better psychosocial outcomes 2 years after hip arthroscopy. Setting positive expectations preoperatively may be important for enhancing psychosocial health postoperatively.

Patient-Reported Outcomes Associated With "Completely Better" Status at 2 Years After Hip Arthroscopy

Background

Measures such as the Patient Acceptable Symptom State and minimum clinically important difference have been used to contextualize patient-reported outcomes (PROs). Assessment of patients' perception of being "completely better" (CB) after hip arthroscopy has not been studied.

Purposes

To (1) determine the prevalence and characteristics of patients who report being CB at 2 years after hip arthroscopy; (2) determine whether PROs measuring function, pain, and mental health are associated with CB status; and (3) determine threshold values for PROs predictive of achieving CB status.

Study Design

Case-control study; Level of evidence, 3.

Methods

Patients undergoing hip arthroscopy at a single institution from October 2015 to January 2020 were administered electronic surveys assessing sociodemographic variables and PROs at baseline and 2 years postoperatively. The CB anchor question was "Is the condition for which you underwent surgery completely better now?" Threshold values for PROs associated with achieving CB status at 2 years postoperatively were identified with 90% specificity. Variables with an area under the curve of >0.80 on a receiver operating characteristic curve were selected for multivariate analysis.

Results

Overall, 29 of 62 patients (47%) achieved CB status. There were no differences in age, sex, body mass index, race, prior hip surgery, preoperative opioid use, smoking status, or preoperative expectations between the CB and no-CB groups. The CB group had better 2-year postoperative and pre- to postoperative change values on all PROs (P < .05 for all) except for the Patient-Reported Outcomes Measurement Information System (PROMIS)-Depression and the Numeric Pain Scale (NPS) for whole-body pain. Two-year postoperative PRO thresholds for achieving CB status were determined as PROMIS-Physical Function (PF) ≥51.3 or increase in PROMIS-PF ≥12 points, PROMIS-Pain Interference ≤46.6 or decrease in PROMIS-Pain Interference ≥12.2 points, NPS for operative hip pain of ≤1.0, Musculoskeletal Outcomes Data Evaluation and Management System-expectations met ≥95.0, and Surgical Satisfaction Questionnaire (SSQ-8) ≥87.5. Multivariate analysis demonstrated that higher SSQ-8 score and greater improvement on the PROMIS-PF were independent predictors of achieving CB status.

Conclusion

Almost half of the study patients perceived being CB at 2 years after hip arthroscopy. Multiple postoperative PROs scores were associated with achieving CB status.

Patient Expectations and Satisfaction in Pediatric Orthopedics

PURPOSE OF REVIEW

The purpose of the current review is to analyze the current literature regarding the tools available to evaluate patient expectations and satisfaction. There have been an increasing number of tools that have been developed and validated for various orthopedic procedures. Despite the growing number of tools, there are a limited number of tools available for pediatric patients.

RECENT FINDINGS

Several tools have been developed in orthopedics to evaluate patient expectations. However, there are no tools that have been validated in the pediatric population. In addition, pediatric patient expectations should be collected in conjunction with parent/caregiver expectations. Although not specifically validated for pediatric patients, there are several tools available that may pertain to pediatric patients including the HSS ACL Expectations Survey, HSS Shoulder Expectations Survey, HSS Knee Surgery Expectations Survey, HSS Foot and Ankle Surgery Expectation Survey, Sunnybrook Surgery Expectations Survey, Musculoskeletal Outcomes Data Evaluation and Management System (MODEMS) Instruments, Quick DASH, and DASH. In terms of patient satisfaction, there are even fewer tools available. Several tools have been developed to evaluate patient satisfaction and five additional tools within orthopedics. Of these tools, there are two that have been validated for pediatric patients: The Swedish Parents Satisfaction Questionnaire and the Scoliosis Research Society-22. There are a growing number of tools to evaluate patient's expectations and satisfaction in the orthopedic literature. Given most of these tools pertain to adult patients, there is a need for further development of tools specifically validated for pediatric patients and their parents/caregivers. Through the measurement of expectations and satisfaction, medical professionals can hope to improve satisfaction and outcomes.

Functional assessment in patients undergoing total hip arthroplasty

Aims

Conventional patient-reported surveys, used for patients undergoing total hip arthroplasty (THA), are limited by subjectivity and recall bias. Objective functional evaluation, such as gait analysis, to delineate a patient's functional capacity and customize surgical interventions, may address these shortcomings. This systematic review endeavours to investigate the application of objective functional assessments in appraising individuals undergoing THA.

Methods

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were applied. Eligible studies of THA patients that conducted at least one type of objective functional assessment both pre- and postoperatively were identified through Embase, Medline/PubMed, and Cochrane Central database-searching from inception to 15 September 2023. The assessments included were subgrouped for analysis: gait analysis, motion analysis, wearables, and strength tests.

Results

A total of 130 studies using 15 distinct objective functional assessment methods (FAMs) were identified. The most frequently used method was instrumented gait/motion analysis, followed by the Timed-Up-and-Go test (TUG), 6 minute walk test, timed stair climbing test, and various strength tests. These assessments were characterized by their diagnostic precision and applicability to daily activities. Wearables were frequently used, offering cost-effectiveness and remote monitoring benefits. However, their accuracy and potential discomfort for patients must be considered.

Conclusion

The integration of objective functional assessments in THA presents promise as a progress-tracking modality for improving patient outcomes. Gait analysis and the TUG, along with advancing wearable sensor technology, have the potential to enhance patient care, surgical planning, and rehabilitation.

Evaluating the Use of PROMs in Paediatric Orthopaedic Registries

Patient-reported outcome measures (PROMs) provide structured information on the patient's health experience and facilitate shared clinical decision-making. Registries that collect PROMs generate essential information about the clinical course and efficacy of interventions. Whilst PROMs are increasingly being used in adult orthopaedic registries, their use in paediatric orthopaedic registries is not well known. The purpose of this systematic review was to identify the frequency and scope of registries that collect PROMs in paediatric orthopaedic patient groups. In July 2023, six databases were systematically searched to identify studies that collected PROMs using a registry amongst patients aged under 18 years with orthopaedic diagnoses. Of 3190 identified articles, 128 unique registries were identified. Three were exclusively paediatric, 27 were majority paediatric, and the remainder included a minority of paediatric patients. One hundred and twenty-eight registries collected 72 different PROMs, and 58% of these PROMs were not validated for a paediatric population. The largest group of orthopaedic registries collected PROMs on knee ligament injuries (21%). There are few reported dedicated orthopaedic registries collecting PROMs in paediatric populations. The majority of PROMs collected amongst paediatric populations by orthopaedic registries are not validated for patients under the age of 18 years. The use of non-validated PROMs by registries greatly impedes their utility and impact. Dedicated orthopaedic registries collecting paediatric-validated PROMs are needed to increase health knowledge, improve decision-making between patients and healthcare providers, and optimise orthopaedic management.

Patient expectations and satisfaction in hand surgery: A new assessment approach through a valid and reliable survey questionnaire

INTRODUCTION

Assessing patient expectations in orthopaedic surgery has gained significant importance over time. However, there have been only a few studies on how to measure such expectations in hand surgery. Against the backdrop, the study was designed to develop a valid and reliable expectations survey for patients undergoing hand surgery and to identify the correlations between preoperative expectations and postoperative satisfaction.

MATERIALS AND METHODS

This is a three-phase prospective cohort study. In the first phase of the study (146 patients), patient expectations were assessed while developing a draft questionnaire based on frequency and clinical relevance. In the second phase (154 patients newly included), test-retest reliability was measured to ensure test consistency. The Intraclass Correlation Coefficient (ICC) served as a basis for developing the final survey questionnaire. In the third phase, we followed up with patients, who completed the preoperative expectations survey, 3 months after surgery to assess the fulfillment of their expectations. The Pearson correlation method was used to measure the association between preoperative expectations and postoperative satisfaction.

RESULTS

In the first phase, 146 patients shared 406 different expectations, which were grouped into nine categories. Then, in the second phase, the final survey was populated by questionnaire items under respective category that have revealed strong test-retest reliability (ICC of 0.91). A significant positive correlation between patient expectations and satisfaction was observed (R = 0.181, p = 0.034).

CONCLUSION

The survey was designed to offer a valid and reliable approach for the comprehensive assessment of patient expectations in hand surgery. The survey results show that patients with high expectations tend to be more satisfied with surgical outcomes. It is strongly believed that this approach would serve as a useful tool at a time when patient perspective is taken into account increasingly more in the clinical practice.

Information needs, expectations, and treatment preference of patients considering spinal surgery: A case-control survey

STUDY DESIGN

Case-control survey.

OBJECTIVES

To explore intrapersonal factors associated with decision of patients with degenerative back pain for surgery.

METHODS

From September 2018 to May 2019 patients were invited to complete a questionnaire. Patients who decided on (case) and declined surgery (control) were later confirmed from medical records.

RESULTS

Seventy-five patients were recruited. Male patients (75.0%, p = 0.019), those who were married (78.7%, p = 0.0045), and had spousal care-givers (89.2%, p < 0.0001) were more likely to decide for surgery. All patients who decided on surgery expressed need for information on "the severity of their spine conditions" (p = 0.039). Those who decided on surgery did not have as the high expectation on "to sleep more comfortably" as those who declined (4.71 vs. 4.91, p = 0.022). The predictive factors for surgery decision by logistic regression analysis were: male gender (OR = 3.23, 95% CI: 1.19-8.77, p = 0.021); married (OR = 5.231, 95% CI: 1.87-14.61, p = 0.002); with available spousal care-giver (OR = 1.85, 95% CI: 0.198-3.89, p = 0.031); and those who preferred to treat/cure the spine disorder by pharmacological treatment (OR = 2.77, 95% CI: 1.02-7.50, p = 0.045).

CONCLUSION

Patients who decided on surgery were likely to indicate need of medical information related to their condition. Patients were in hope of better relief of physical symptoms, especially related to sleep comfort. Patients would escalate their treatment from conservative to surgery when conservative treatments were no longer effective.

Response Bias for Press Ganey Ambulatory Surgery Surveys after Knee Surgery

The Press Ganey Ambulatory Surgery (PGAS) survey is an emerging tool used to capture patient satisfaction after elective surgery. Evaluating patient satisfaction is important; however, quality improvement (QI) surveys used to capture the patient experience may be subject to nonresponse bias. An orthopaedic registry was used to retrospectively identify patients who underwent ambulatory knee surgery from June 2015 to December 2019. Multivariable logistic regression was performed to identify independent predictors of PGAS survey nonresponse and response. In the cohort of 1,161 patients, 142 (12.2%) completed the PGAS survey. Multiple logistic regression demonstrated that male sex, Black race, not living with a caretaker, student or unemployment status, and worse preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) fatigue were predictors of nonresponse. The results of this study highlight the presence of nonresponse bias in the PGAS survey after elective knee surgery.

Predictors of PROMIS Physical Function at 2 Years following Knee Surgery

The purpose of this study was to evaluate Patient-Reported Outcomes Measurement Information System physical function (PROMIS PF) 2 years following knee surgery, and identify preoperative factors associated with postoperative PROMIS PF. Three hundred and sixty-five patients, age 17 years and older, undergoing knee surgery at one institution were studied. Patients completed multiple questionnaires prior to surgery and again 2 years postoperatively including PROMIS PF, International Knee Documentation Committee (IKDC), joint and body numeric pain scales (NPS), Tegner's activity scale (TAS), and Marx's activity rating scale (MARS). Mean PROMIS PF improved from 41.4 to 50.9 at 2 years postoperatively (p < 0.001) and was strongly correlated with 2-year IKDC scores. Older age, female gender, non-Hispanic ethnicity, unemployment, lower income, government insurance, smoking, preoperative opioid use, having a legal claim, comorbidities, previous surgeries, higher body mass index (BMI), and knee arthroplasty were associated with worse 2-year PROMIS PF. Multivariable analysis confirmed that lower BMI, less NPS body pain, and higher MARS were independent predictors of greater 2-year PROMIS PF and better improvement in PROMIS PF. In this large, broad cohort of knee surgery patients, multiple preoperative factors were associated with PROMIS PF 2 years postoperatively. PROMIS PF scores improved significantly, but worse 2 year PROMIS PF scores and less improvement from baseline were independently predicted by higher BMI, greater NPS body pain, and lower MARS activity level. PROMIS PF can be implemented as an efficient means to assess outcomes after knee surgery.

Predictors of met expectations two years after knee surgery

Introduction

The purpose of this study is to determine which patient factors predict two-year postoperative met expectations in a cohort of patients undergoing knee surgery. Additionally, this study aims to measure the association between met expectations and postoperative outcomes.

Methods

319 patients undergoing knee surgery at one institution were studied. Patients completed patient-reported outcome questionnaires prior to surgery and again two years postoperatively. Preoperative Expectations and postoperative Met Expectations were measured using the Musculoskeletal Outcomes and Data Evaluation Management System (MODEMS) Expectations domain.

Results

The mean Met Expectations score was significantly lower than the preoperative Expectations Score. Worse two-year Met Expectations were associated with older age, higher BMI, greater comorbidities, more previous surgeries, black race, unemployment, lower income, government insurance, Worker's Compensation, smoking, and no injury prior to surgery. Greater Met Expectations were correlated with better scores on all two-year outcome measures as well as greater improvement on most outcome measures. Race, insurance status, function, mental health, and knee pain were found to be independent predictors of Met Expectations.

Conclusion

This study identified multiple patient factors and outcome measures that were associated with Met Expectations two years after knee surgery.

Walk a Mile in the Leadership's Shoes: Why Focus on Quality Improvement?

Quality Improvement (QI) throughout health care in the United States continues to be of growing importance to both patients and providers. Leaders in health care including physicians, nurses, hospital administrators, and payors are all responsible for ensuring the continuation and growth of QI initiatives. This article will discuss various ways that healthcare leaders, with specific regard to orthopedic surgery, have utilized QI measures to provide better, more efficient, care to patients.

Big Data, Big Research: Implementing Population Health-Based Research Models and Integrating Care to Reduce Cost and Improve Outcomes

Recent trends in clinical research have moved attention toward reporting clinical outcomes and resource consumption associated with various care processes. This change is the result of technological advancement and a national effort to critically assess health care delivery. As orthopedic surgeons traverse an unchartered health care environment, a more complete understanding of how clinical research is conducted using large data sets is necessary. The purpose of this article is to review various advantages and disadvantages of large data sets available for orthopaedic use, examine their ideal use, and report how they are being implemented nationwide.

Patient Centeredness in Total Joint Replacement: Beyond the Slogan

Patient-centered care (PCC) is gaining considerable momentum among health care professionals and policy-making authorities. The need for PCC stems from the innumerable benefits of adopting such a system. The practice of PCC in orthopedic surgery in general, and in total joint replacement in particular, is still in its youth. However, present literature already establishes the need for applying PCC in total joint replacement. Extensive research and effort should be invested to better grasp and define the dimensions of PCC as they relate to total joint replacement.

Health policy implications of outcomes measurement in orthopaedics

An emphasis on "value" over volume in health care is driving new healthcare measurement, delivery, and payment models. Orthopaedic surgery is a major contributor to healthcare spending and, as such, is the focus of many of these new models. WHERE ARE WE NOW?: An evaluation of "value" in orthopaedics requires information that has not traditionally been collected as part of routine clinical practice. If value is defined as patient outcomes in relation to healthcare costs, we need to collect information about both. In orthopaedics, patient-reported functional status is not routinely measured, and a poor understanding of the costs associated with the provision of musculoskeletal care limits our ability to quantify and report on financial measures. WHERE DO WE NEED TO GO?: To improve the value of musculoskeletal care, we need to focus on both improving outcomes and controlling costs. To improve outcomes, orthopaedists must agree on a set of outcome measures for appropriate care and advocate for their collection through the use of registries. Orthopaedic registries in several countries provide best practices for this information collection and sharing. In the United States, we should make comparable investments in registries to measure patient-reported outcomes. To address escalating costs, we need to improve the accuracy of cost data by applying modern cost accounting processes. HOW DO WE GET THERE?: Orthopaedists should take a leadership position in the promotion and implementation of value-based health care by advocating for the use of registries to measure risk-adjusted patient specific outcomes, negotiating with payors for value-based payment incentives and applying modern cost accounting processes to control costs rather than waiting for public and private payors to define components of the value equation that will affect how orthopaedic surgeons are evaluated and compensated in the future.

Stakeholders in outcome measures: review from a clinical perspective

Modern interest in patient-reported outcomes measures (PROMs) in orthopaedics dates back to the mid-1980s. While gradual growth of activity in this area has occurred over the past 25 years, the extent to which this research methodology is applied in clinical practice to improve patient care is unclear. WHERE ARE WE NOW?: Historically, clinical research in orthopaedics has focused on the technical success of treatment, and objective indicators such as mortality, morbidity, and complications. By contrast, the PROMs framework focuses on effects of treatment described in terms of relief of symptoms, restoring functional ability, and improving quality of life. PROMs can be used to study the relative effects of disease, injury, and treatment across different health conditions. WHERE DO WE NEED TO GO?: All clinical research should begin with identifying clear and meaningful research questions so that the resources and efforts required for data collection result in useful data. Different consumers of research data have different perspectives on what comprises meaningful information. Involving stakeholders such as patients, providers, payers, and policy-makers when defining priorities in the larger research endeavor is one way to inform what type of data should be collected in a particular study. HOW DO WE GET THERE?: Widespread collection of outcomes data would potentially aid these stakeholders by identifying best practices, benefits and costs, and important patient or practice characteristics related to outcomes. Several initiatives currently underway may help systematic collection of PROMs, create efficient systems, and foster collaborations to provide support and resources to minimize costs.

Measuring expectations in orthopaedic surgery: a systematic review

BACKGROUND

Advances in the surgical treatment of musculoskeletal conditions have resulted in an interest in better defining and understanding patients' expectations of these procedures, but the best ways to do this remain a topic of considerable debate.

QUESTIONS/PURPOSES

(1) What validated instruments for the assessment of patient expectations of orthopaedic surgery have been used in published studies to date? (2) How were these expectation measures developed and validated? (3) What unvalidated instruments for the assessment of patient expectations have been used in published studies to date?

METHODS

A systematic literature search was performed using the OVID Medline and EMBASE databases, in duplicate, to identify all studies that assessed patient expectations in orthopaedic surgery. Sixty-six studies were ultimately included in the present review.

RESULTS

Seven validated expectation instruments were identified, all of which use patient-reported questionnaires. Five were specific to a particular procedure or affected anatomic location, whereas two were broadly applicable. Details of reliability and validity testing were available for all but one of these instruments. Forty additional unvalidated expectation assessment tools were identified. Thirteen were based on existing clinical outcome tools, and the others were study-specific, custom-developed tools. Only one of the unvalidated tools was used in more than one study.

CONCLUSIONS

Several validated expectation instruments have been developed for use by patients undergoing orthopaedic surgery. However, many tools have been reported without evidence of testing and validation. The wide range of untested instruments used in single studies substantially limits the interpretation and comparison of data concerning patient expectations.

Psychometric analysis of measuring functional outcomes in tibial plateau fractures using the Short Form 36 (SF-36), Short Musculoskeletal Function Assessment (SMFA) and the Western Ontario McMaster Osteoarthritis (WOMAC) questionnaires

Patients participating in a modern prospective orthopaedic trauma database may be asked to complete many functional outcome measures, adding to the burden of study participation. This prospective study assessed the utility and responsiveness of the generic Short Form 36 (SF-36) and the disease specific Short Musculoskeletal Function Assessment (SMFA) and the Western Ontario McMaster Osteoarthritis (WOMAC) questionnaires in 55 patients treated operatively for tibial plateau fractures with the goal of determining if there was clear benefit of using multiple measures in a lower extremity peri-articular fracture population. There was very good correlation between all three scores at 6 and 12 months, indicating they are measuring similar factors. Responsiveness was assessed using the standard response mean (SRM), proportion of patients attaining the minimal clinically important difference (MCID) between 6 and 12 months, and floor and ceiling effects. The SRM for the SF-36 was statistically higher than the SRM for the SMFA or the WOMAC. Significantly more patients were found to have a MCID between 6 and 12 months post-surgery based on the SF-36 than the other two functional scores. There was no floor effect found on any of the 3 functional scores evaluated; however, a significant ceiling effect was noted with the WOMAC but not with the SF-36 or the SMFA. These results, along with the usefulness of the SF-36 for comparing disease burden across populations, favour the SF-36 as the instrument of choice in assessing functional outcome in patients with tibial plateau fractures.

Relationship between preoperative expectations, satisfaction, and functional outcomes in patients undergoing lumbar and cervical spine surgery: a multicenter study

STUDY DESIGN

Analysis of prospectively collected multicenter data.

OBJECTIVE

To explore the relationship between preoperative expectations and postoperative outcomes and satisfaction in lumbar and cervical spine surgery.

SUMMARY OF BACKGROUND DATA

Back pain is one of the most common health problems, leading to the utilization of health care resources, work loss, and sick benefits. Patient expectations influence posttreatment outcomes, both surgical and nonsurgical. There is little research on the importance of preoperative expectations in spine surgery. Existing studies evaluate the technical aspects of interventions and functional outcomes but fail to take into account patient expectations. The authors hypothesized that expectations dramatically affect spine patient satisfaction independent of functional outcomes.

METHODS

Prospectively collected patient-entered data from patients undergoing lumbar and cervical spine surgery from 2 study centers collected using a Web-based patient health survey system were analyzed. The study included patients who underwent operative intervention (decompression with or without fusion) with at least a 3-month period of follow-up. Preoperative expectations were measured using the Musculoskeletal Outcomes Data Evaluation and Management System's (MODEMS) expectation survey. Postoperative satisfaction and fulfillment of expectations were measured using the MODEMS satisfaction survey. Postoperative functional outcomes were measured using the Oswestry Disability Index and 36-item short form health survey. Ordinal logistic regression multivariate modeling was used to examine predictors of postoperative satisfaction. Linear regression multivariate modeling was used to examine predictors of functional outcomes.

RESULTS

Greater fulfillment of expectations led to higher postoperative satisfaction and was associated with better functional outcomes. Higher preoperative expectations led to decreased postsurgical satisfaction but were associated with improved functional outcomes. Higher postoperative satisfaction was associated with improved functional outcomes and vice versa. Type of surgery also influenced satisfaction and function, with cervical patients being less satisfied but having better functional outcomes than lumbar patients.

CONCLUSION

This study showed that more than functional outcomes matter; preoperative expectations and fulfillment of expectations influence postoperative satisfaction in patients undergoing lumbar and cervical spine surgery. This underlines the importance of taking preoperative expectations into account to obtain an informed choice on the basis of the patient's preferences.

Medical Test Results Do Not Tell the Whole Story

Children born today with congenital heart disease (CHD) are likely to reach adulthood, even those with complex disease. As survival rates have increased, attention has focused on the longer-term morbidity associated with CHD and its treatment, but this has largely addressed the physical and physiological outcomes rather than psychosocial morbidity and health-related quality of life (QoL). The purpose of this article is to outline the arguments in favor of routine evaluation of health-related QoL, describe how such measurements might be used, and the barriers and challenges associated with the collection of the data. Finally, a strategy is suggested for the routine collection and use of health-related QoL data with children and adolescents with CHD.

The role of SIGN in the development of a global orthopaedic trauma database

BACKGROUND

The global burden of injury is receiving recognition as a major public health problem but inadequate information delays many proposed solutions. Many attempts to collect reliable data on orthopaedic trauma have been unsuccessful. The Surgical Implant Generation Network (SIGN) database is one of the largest collections of fracture cases from lower and middle income countries.

QUESTIONS/PURPOSES

We describe the information in the SIGN database then address two questions: In the context of the design and implementation of a global trauma database, what lessons does the SIGN database teach? Does the SIGN program have a role in the evolution of a wider global system?

METHODS

The SIGN database is Internet based. After treating a patient with a SIGN nail surgeons enter radiographs and details of the case.

RESULTS

Over 26000 cases are in the SIGN database. The database has been used as a source of cases for followup studies. Analysis shows the data are of sufficient quality to allow studies of fracture patterns but not for outcome studies or bone measurement. WHERE DO WE NEED TO GO?: A global database with more comprehensive coverage of injuries, causes, treatment modalities and outcomes is needed. HOW DO WE GET THERE?: The SIGN database itself will not become a global trauma database (GTD) but the personnel of the SIGN program have much to offer in the design and adoption of a GTD. Studies of suitable methods of data collection and the incentive to use them are required.

Variability in hip range of motion on clinical examination

The goal of this study was to determine the interobserver and intraobserver reliability of physical examination in determining hip range of motion. Twenty normal hips, 21 hips with osteoarthritis, and 21 hips of patients more than 12 months after a total hip arthroplasty were examined for visual passive range of motion. These 62 hips were examined by 2 experienced surgeons and by 3 trainees. The 2 experienced examiners repeated their clinical examinations in 19 patients to determine the intraobserver reliability. Intraclass correlation coefficients (ICCs) indicated moderate interobserver agreement in estimates of clinical hip motion (ICC for hip flexion, 0.56 +/- 0.12; for hip abduction, 0.48 +/- 0.13). Intraclass correlation coefficients also suggest only moderate intraobserver reliability in measurements of hip motion (ICC for hip flexion, 0.62 +/- 0.14; hip abduction, 0.44 +/- 0.20). More reliable and accurate methods are needed to measure clinical hip motion before and after total hip arthroplasty.

Gait and stair function in total and resurfacing hip arthroplasty: a pilot study

Standard total hip arthroplasty (THA) is the established surgical treatment for patients older than 65 years with progressive osteoarthritis but survivorship curves wane in patients younger than 50. Resurfacing hip arthroplasty (RHA) is an alternative for younger, active patients reportedly providing superior range of motion. Quantitative investigation of functional recovery following arthroplasty may elucidate limitations that aid in device selection. Although limited long-term kinematic data are available, the early rate of recovery and gait compensations are not well described. This information may aid in refining rehabilitation protocols based on limitations specific to the implant. We presumed hip motion and forces for subjects receiving RHA are more similar to age-matched controls during physically demanding tasks, such as stair negotiation, at early time points than those for THA. In a pilot study, we quantified walking and stair negotiation preoperatively and 3 months postoperatively for seven patients with RHA (mean age, 49 years), seven patients with standard THA (mean age, 52 years), and seven age-matched control subjects (mean age, 56 years). Although both treatment groups demonstrated trends toward functional recovery, the RHA group had greater improvements in hip extension and abduction moment indicating typical loading of the hip. Further investigation is needed to determine if differences persist long term or are clinically meaningful.

Defining the effect and mediators of two knowledge translation strategies designed to alter knowledge, intent and clinical utilization of rehabilitation outcome measures: a study protocol [NCT00298727]

BACKGROUND

A substantial number of valid outcome measures have been developed to measure health in adult musculoskeletal and childhood disability. Regrettably, national initiatives have merely resulted in changes in attitude, while utilization remains unacceptably low. This study will compare the effectiveness and mediators of two different knowledge transfer (KT) interventions in terms of their impact on changing knowledge and behavior (utilization and clinical reasoning) related to health outcome measures.

METHOD/DESIGN

Physical and occupational therapists (n = 144) will be recruited in partnership with the national professional associations to evaluate two different KT interventions with the same curriculum: 1) Stakeholder-Hosted Interactive Problem-Based Seminar (SHIPS), and 2) Online Problem-Based course (e-PBL). SHIPS will consist of face-to-face problem-based learning (PBL) for 2 1/2 days with outcome measure developers as facilitators, using six problems generated in consultation with participants. The e-PBL will consist of a 6-week web-based course with six generic problems developed by content experts. SHIPS will be conducted in three urban centers in Canada. Participants will be block-allocated by a minimization procedure to either of the two interventions to minimize any prognostic differences. Trained evaluators at each site will conduct chart audits and chart-stimulated recall. Trained interviewers will conduct semi-structured interviews focused on identifying critical elements in KT and implementing practice changes. Interviews will be transcribed verbatim. Baseline predictors including demographics, knowledge, attitudes/barriers regarding outcome measures, and Readiness to Change will be assessed by self-report. Immediately post-intervention and 6 months later, these will be re-administered. Primary qualitative and quantitative evaluations will be conducted 6-months post-intervention to assess the relative effectiveness of KT interventions and to identify elements that contribute to changing clinical behavior. Chart audits will determine the utilization of outcome measures (counts). Incorporation of outcome measures into clinical reasoning will be assessed using an innovative technique: chart-stimulated recall.

DISCUSSION

A strategy for optimal transfer of health outcome measures into practice will be developed and shared with multiple disciplines involved in primary and specialty management of musculoskeletal and childhood disability.

The Effect of Single-Injection Femoral Nerve Block Versus Continuous Femoral Nerve Block After Total Knee Arthroplasty on Hospital Length of Stay and Long-Term Functional Recovery Within an Established Clinical Pathway

Total knee arthroplasty (TKA) may result in severe pain, and single-injection femoral nerve blocks (SFNB) have been demonstrated to have a limited duration of analgesia. Continuous femoral nerve blocks (CFNB) can prolong the analgesic duration of SFNB. We prospectively randomized 36 patients undergoing TKA to CFNB versus SFNB and evaluated the effect on hospital length of stay (LOS) as the primary outcome within a standardized clinical pathway. Secondary outcomes included visual analog scale (VAS) pain scores, opioid consumption, and long-term functional recovery at 12 wk. Mean VAS resting scores were significantly lower among patients who received CFNB versus SFNB: first day (1.7 vs 3.3 [P = 0.002]) and second day (0.9 vs 3.2 [P < 0.0001]) after surgery. Mean maximal VAS scores during physical therapy were significantly lower among patients who received CFNB versus SFNB: first day (4.7 vs 6.3 [P = 0.01]) and second day (3.9 vs 6.1 [P = 0.0005]) after surgery. Mean oxycodone consumption was significantly lower among patients who received CFNB versus SFNB: 15 mg versus 40 mg (P = or < 0.0001) on the first day after surgery; 20 mg versus 43 mg (P = 0.0004) on the second day after surgery. There was no difference in hospital LOS (3.8 vs 3.9 days) or long-term functional recovery (117 degrees versus 113 degrees knee flexion at 12 wk) between the two groups. The lack of effect provided by increased duration of analgesia (from CFNB) after TKA may now have minimal impact on hospital LOS and long-term functional recovery in the contemporary healthcare environment within the United States.
