What's important: postoperative care planning. recognizing the central role of pets in many patients' lives.
Pets are important in many of our lives, and so they are important during the recovery period following events like hip or knee surgery. This study was born from a reflection on the question of pet ownership as the investigators studied outcomes that patients desired from orthopaedic surgery and factors in their lives that they identified as important to their aftercare planning.

Neighbors-based prediction of physical function after total knee arthroplasty.
The purpose of this study was to develop and test personalized predictions for functional recovery after Total Knee Arthroplasty (TKA) surgery, using a novel neighbors-based prediction approach. Findings showed that predictions were well-calibrated in out-of-sample testing. These predictions have the potential to inform care decisions both prior to and following TKA surgery.

Association of occupational and physical therapy with duration of prescription opioid use after hip or knee arthroplasty: A retrospective cohort study of Medicare enrollees.
The purpose of this study was to establish whether non-pharmacological interventions, such as occupational and physical therapy, were associated with a shorter duration of prescription opioid use after hip or knee arthroplasty. The investigators concluded that occupational and physical therapy with home health were associated with a shorter duration of prescription opioid use after hip and knee arthroplasty.

Surgical skill can be objectively measured from fluoroscopic images using a novel image-based Decision Error Analysis (IDEA) score.
This study introduces and evaluates a novel Image-based Decision Error Analysis (IDEA) score that captures performance during fluoroscopically assisted wire navigation. Findings showed that the fluoroscopic images obtained in the course of placing a guide wire contained a rich amount of information related to surgical skill. The IDEA scoring provided a basis for evaluating the competence of a resident. The score can be used to assess skill at key timepoints throughout residency, such as when rotating onto/off of a new surgical service and before performing certain procedures in the operating room, or as a tool for debriefing/providing feedback after a procedure is completed.

Increased utilization of total joint arthroplasty after Medicaid expansion.
This study examined prior analyses that greater utilization of total hip arthroplasty (THA) and total knee arthroplasty (TKA) was to be expected after Medicaid expansion in 2014. Using 2012-2015 data from the HCUP Database, 9 expansion states (Arkansas, Arizona, Colorado, Iowa, Massachusetts, Maryland, Nevada, New York, and Vermont) were compared to 2 states that did not expand Medicaid (Florida and Missouri). After adjusting for community characteristics, THA and TKA increased 15% in 2014 and 23% in 2015 within expansion states compared to 2013. In non-expansion states, compared to 2013, there were significant decreases of 18% in 2014 and 11% in 2015.

Patient-reported opioid consumption and pain intensity after common orthopedic and urologic surgical procedures with use of an automated text messaging system.
This prospective study looked at the number of opioid tablets taken compared to the number prescribed after orthopedic and urologic surgery at a large urban academic health center in Pennsylvania from May to December 2019 with the use of an automated text messaging system. Of the 919 study participants, 80.7% (742) underwent orthopedic procedures and 19.2% underwent urologic procedures. Among those who underwent orthopedic procedures, 384 were women, 491 were White, and the median age was 48 years; with almost 70% outpatient procedures. Among those who underwent urologic procedures, 84.8% were men, 80.7% were White, and the median age was 56 years; 62% had an outpatient procedure. Orthopedic patients were prescribed an average of 20 tablets and urologic patients 7 tablets. The majority of patients (64.1%) used less than half of the amount prescribed, and 256 orthopedic and 77 urologic patients did not use any opioids. The findings suggest that clinicians can tailor prescriptions to limit excess quantities of prescribed opioids.

A randomized controlled trial comparing two self-administered educational strategies for patients with knee osteoarthritis.
The authors conducted a randomized clinical trial in patients with knee osteoarthritis to assess the efficacy of providing a video for entertainment education, in combination with two booklets, compared with providing the booklets alone. They found that, although both education strategies were associated with improved knowledge and reduced decisional conflict at 6 months, receiving the video + booklets in combination, compared with receiving the booklets alone, proved to be more effective in changing behaviors and appeared to have some advantages for Spanish speakers and those who were less educated.

Analysis of patient income in the 5 years following a fracture treated surgically.
Investigators characterized the association between orthopedic injury and patient income using state tax records. They found that, in this cohort study of patients surgically treated for an orthopedic fracture at a US academic trauma center, fractures were associated with substantial individual and household income loss up to 5 years after injury, and 1 in 5 patients sustained catastrophic income loss in the 2 years after fracture. Gains in Social Security benefits offset less than 10% of annual income losses.

Associations between comorbidity and quality of life outcomes after total joint replacement.
In this study, a cross-sectional, questionnaire-based national survey, the authors examined associations between self-reported and clinician-assessed comorbidity and quality of life (QOL) outcomes after hip and knee replacement. The investigators concluded that the results showed that general QOL outcomes following hip and knee joint replacement, while typically high, were associated with comorbidity burden and BMI.

A portable system for remote rehabilitation following a total knee replacement: a pilot randomized controlled clinical study.
The authors have developed and previously validated the accuracy of a remote (wearable) rehabilitation monitoring platform (interACTION). The present study's objective was to assess the feasibility of utilizing interACTION for the remote management of rehabilitation after total knee replacement (TKR) and to determine a preliminary estimate of the effects of the interACTION system on the value of rehabilitation. Findings showed that all patients and physical therapists in the interACTION Group indicated that they would use the system again in the future. Therefore, the next steps are to address the concerns identified in this pilot study and to expand the platform to include behavioral change strategies prior to conducting a full-scale randomized controlled trial.

Effect of outpatient rehabilitation on functional mobility after single total knee arthroplasty: a randomized clinical trial.
Researchers compared post-total knee arthroplasty (TKA) functional mobility outcomes among 3 newly-developed physical therapy protocols with a standard-of-care post-TKA rehabilitation protocol. They found no statistically or clinically significant differences in outcomes across the 4 study arms (control, treadmill, neuromuscular stimulation device, and combination intervention). As outcomes were similar among arms, they recommended that clinicians instead consider relative cost in tailoring TKA rehabilitation.

Validation of an electronic coding algorithm to identify the primary indication of orthopedic surgeries from administrative data.
The purpose of this study was to develop and validate an algorithm to identify patients receiving four elective orthopedic surgeries to promote shared decision-making. The surgeries included were: 1) knee arthroplasty to treat knee osteoarthritis (KOA); 2) hip arthroplasty to treat hip osteoarthritis (HOA); 3) spinal surgery to treat lumbar spinal stenosis (SpS); and 4) spinal surgery to treat lumber herniated disc (HD). Electronic medical records were reviewed to ascertain a “gold standard” determination of the procedure and primary indication status. Each case had electronic algorithms consisting of ICD-10 and CPT codes for each combination and indication applied to their record. A total of 790 procedures were included in the study. The sensitivity of the algorithms ranged from 0.70 (HD) to 0.92 (KOA). Specificity ranged from 0.94 (SpS) to 0.99 (HOA, KOA).

Can vertically integrated health systems provide greater value: the case of hospitals under the comprehensive care for joint replacement model?
The authors sought to assess whether system providers perform better than non-system providers under an alternative payment model that incentivizes high-quality, cost-efficient care. Using CMS data linked to AHRQ’s Compendium of US Health Systems, along with secondary sources, they found that when operating under alternative payment model incentives, vertical integration may enable hospitals to lower costs with similar quality scores.

Potential selection bias in observational studies comparing cervical disc arthroplasty to anterior cervical discectomy and fusion.
This retrospective cohort study looked at potential selection bias for spinal patients undergoing cervical disc arthroplasty (CDA) or anterior cervical discectomy and fusion (ACDF). A total of ACDF or CDA 290,419 procedures were identified in adults from 2004-2014 using ICD-9-CM diagnosis and procedure codes. The vast majority (98.2%) underwent ACDF. CDA patients were younger and healthier with a higher socioeconomic status than ACDF patients. CDA was also $574 more expensive in the fully specified model. There was no statistically significant difference in terms of complications between the two procedures.

Development of a reference chart to monitor postoperative swelling following total knee arthroplasty.
The purpose of this study was to develop a reference chart to monitor postoperative swelling following total knee arthroplasty. Until recently, there was no reliable way to accurately measure swelling in clinical settings, but bioelectrical impedance assessment has shown promise. The authors worked with 56 participants who were followed for the first 7 weeks following total knee arthroplasty. Frequent lower extremity bioelectrical impedance assessment data was collected from the first 40 patients rolled in the study with the remaining 16 patients preliminarily tested. The first 3 days following surgery showed an approximately 10% per day increase with peak swelling occurring 6-8 days after surgery, with a range of 25% for the 10th percentile and 47% for the 90th percentile. It is hoped this monitoring will improve clinical decision making at the individual level.

Trajectory analysis for postoperative pain using electronic health records: a nonparametric method with robust linear regression and K-medians cluster analysis.
Postoperative pain scores are widely monitored and collected in the electronic health record, yet current methods fail to fully leverage the data with fast implementation. This article describes a trajectory analysis for postoperative pain using electronic health records. A robust linear regression was fitted to describe the association between the log-scaled pain score and time from discharge after total knee replacement.

Potential role of cost and quality of life in treatment decisions for arthritis-related knee pain in African American and Latina women.
This study examined whether using a decision-making tool would aid Latina and African-American women over age 45 years with arthritic knee pain in making more informed treatment decisions. The researchers conducted 4 focus groups of Latina and African-American women and 2 focus groups with primary care providers who treated them for knee pain. They found that minority women and primary care providers all endorsed the use of a decision-making tool that provided information on the impact of treatment on quality of life, medical care costs, and work productivity.

"Surprise" out-of-network billing in orthopedic surgery: charges from surprising sources.
This study examined “surprise” out-of-network billing in orthopedic surgery. Data was analyzed from the Clinformatics DataMart on commercial insured patients undergoing 4 different elective orthopedic procedures from 2012 to 2017: arthroscopic meniscal repair, lumbar discectomy, total knee replacement and total hip replacement. They defined surprise bills as out-of-network bills for procedures done at in-network hospitals. The rate of potential surprise bills was 24.8% for total knee replacement, 24.5% lumbar discectomy, 23.5% for total hip replacement, and 12.5% for meniscal repair. The largest number of surprise bills came from anesthesiologists (39% of all episodes), and durable medical equipment (15%). Per episode, the largest bills came from nonphysician surgical assistants, neurologists, and physician assistants.

What outcomes matter to patients after joint or spine surgery?
In this study, semi-structured interviews were conducted with 65 patients undergoing hip or knee replacement, spinal discectomy/laminectomy, or a spinal fusion to examine what patient-reported outcome measures (PROMs) patients identified as most important. The investigators found that patients identified specific preferred outcomes from these surgical procedures that were important and meaningful to them and that framed whether they saw their surgery as a success. They also identified personal factors that they assumed their surgeons knew about, which affected their care and recovery.

The effects of bundled payment programs for hip and knee arthroplasty on patient-reported outcomes.
This study compared outcomes for patients undergoing hip and knee arthroplasty at hospitals participating in Medicare’s bundled payment programs with hospitals that do not. They performed a prospective observational study using the Comparative Effectiveness of Pulmonary Embolism Prevention after Hip and Knee replacement trial. Differences through 6 months were observed. Outcomes were described using the brief Knee Injury and Osteoarthritis Outcomes Score or the brief Hip Disability and Osteoarthritis Outcomes Score, the Patient-Reported Outcomes Measurement Information System Physical Health Score, and the Numeric Pain Rating Scale. While there slightly lower improvement at nonbundled hospitals at first, overall the effects were small.

Patient-reported outcomes following total hip arthroplasty: a multicenter comparison based on surgical approaches.
This study looked at patient-reported outcomes (PROs) from patients who underwent total hip arthroplasty (THA) in the United States. The cohort examined were participants in the Comparative Effectiveness of Pulmonary Embolism Prevention after Hip and Knee Replacement study. The researchers compared PROs between posterior, transgluteal, and anterior surgical approaches to THA. Patients were surveyed on function, global health and pain at 1, 3, and 6 months postoperatively at 26 sites from the clinical trial. Outcomes from 3018 eligible participants were examined from December 2016 through August 2019. While there was lower improvement in hip disability and Osteoarthritis Outcomes Score at first with the transgluteal cohort, by 3 and 6 months there was no clinically significant differences between the three groups.

Person-centered care and physical therapy: a "people-like-me" approach.
In this perspective paper, the authors propose developing "people-like-me" reference charts, generated with historical outcomes data, to provide real-time information on an individual's status relative to similar people, using as an example people rehabilitating after total knee arthroplasty. The authors propose this framework as a practical mechanism to advance person-centered decisions in physical therapy according to the ideals of evidence-based practice.

Patient outcomes following total joint replacement surgery: a comparison of hospitals and ambulatory surgery centers.
This study used a large claims database of non-Medicare patients to examine inpatient and outpatient total knee replacement and total hip replacement surgery performed on a near-elderly population during 2014-2016. Findings support the argument that outpatient total joint replacement is appropriate for select patients treated in both hospital outpatient departments and ambulatory surgery centers, although in the commercially insured population, the latter services may come at a cost. Until further study of outpatient total joint replacement in the Medicare population becomes available, how this will extrapolate to the Medicare population is unknown.
