2019 American College of Rheumatology recommended patient-reported functional status assessment measures in rheumatoid arthritis.
This study’s objective was to develop American College of Rheumatology (ACR) Functional Status Assessment Measures (FSAMs) for patient reporting in most clinic settings. The authors convened a workgroup to conduct a systematic literature review through March 2017. They focused on the following FSAMs: the Health Assessment Questionnaire (HAQ) and derived measures from the Patient-Reported Outcomes Measurement Information System (PROMIS) tool. Out of 11,835 articles identified in the search, 56 were included in the review. A modified Delphi process identified 7 measures which fulfilled the minimum standard for regular use, and 3 measures were recommended: the PROMIS 10-item short form, the HAQ-II, and the Multidimensional HAQ.

Comparison of three measures of shared decision making: SDM Process_4, CollaboRATE, and SURE scales.
This study compared 3 different shared decision making (SDM) aids for patients facing surgery for hip or knee osteoarthritis, lumbar herniated disc or lumber spinal stenosis (backs). Patients were surveys after they used one of the following patient decision aids (PDAs): SMD Process_4, CollaboRATE, or SURE. The sample size was 649 with a mean age of 63.3 years, 51% female, and 60% were college educated. Most patients (69%) were facing hip or knee surgery. Results showed that the PDAs did aid patients – especially for hips/knees and were different for each PDA.

Contraception use among reproductive-age women with rheumatic diseases.
The purpose of this study was to determine contraception use among a cohort of reproductive-age women with rheumatic diseases. Women who had one of 21 possible rheumatic disease diagnoses, and had at least two outpatient rheumatology visits, were included. Findings revealed low use of prescription contraception, and the authors recommended urgent efforts to improve contraceptive care and access for some women with rheumatic diseases.

Association of preoperative opioid use with mortality and short-term safety outcomes after total knee replacement.
The purpose of this study was to determine the association of preoperative opioid use among patients 65 years and older with mortality and other complications at 30 days post-total knee replacement (TKR). Findings show that continuous opioid users had a higher risk of revision operations, vertebral fractures, and opioid overdose at 30 days post-TKR but not of in-hospital or 30-day mortality, compared with opioid-naive patients. Highlights include the need for better understanding of patient characteristics associated with chronic opioid use to optimize preoperative assessment of overall risk after TKR.

A 12-item short form of the Hip disability and Osteoarthritis Outcome Score (HOOS-12): tests of reliability, validity and responsiveness.
The goal of this study was to measure validity, reliability and responsiveness of the 12-item version of the 40-item Hip disability and Osteoarthritis Outcome Score (HOOS) surveys that measure joint-specific pain, function and quality of life (QOL) for patients. The shorter forms were given to 1,281 hip OA patients from the FORCE-TJR cohort who had previously completed the HOOS surveys before and after total joint replacement surgery. The HOOS-12 survey was compared to the full-length HOOS, HOOS-PS, and HOOS, JR surveys. Internal consistency reliability was above 0.70 for all HOOS-12 scales and above 0.90 for the Summary score. Validity and responsiveness were also found to be comparable to full-length HOOS scales.

Item selection for 12-item short forms of the Knee injury and Osteoarthritis Outcome Score (KOOS-12) and Hip disability and Osteoarthritis Outcome Score (HOOS-12).
The goal of this study was to develop 12-item versions of the 42-item Knee injury and Osteoarthritis Outcome Score (KOOS) and 40-item Hip disability and Osteoarthritis Outcome Score (HOOS) surveys that measure joint-specific pain, function and quality of life (QOL) for patients. The shorter forms were given to 1,395 knee osteoarthritis (OA) and 1,281 hip OA patients from the FORCE-TJR cohort who had previously completed the KOOS and HOOS surveys before and after total joint replacement surgery. The KOOS-12 and HOOS-12 surveys were found to successfully measure pain and function items of the patients as well as the 42-item versions.

A 12-item short form of the Knee injury and Osteoarthritis Outcome Score (KOOS-12): tests of reliability, validity and responsiveness.
The purpose of this study was to evaluate reliability, validity and responsiveness of KOOS-12, a 12-item short form of the 42-item Knee injury and Osteoarthritis Outcome Score (KOOS) that provides Pain, Function and Quality of Life (QOL) scale scores and a summary knee impact score. Results showed that KOOS-12 was a reliable and valid alternative to KOOS in total knee replacement patients with moderate to severe knee osteoarthritis and provided three domain-specific and summary knee impact scores with substantially reduced respondent burden.

Limited health literacy and patient confusion about rheumatoid arthritis patient global assessments and model disease states.
The objective of this study was to understand the perspectives of vulnerable patients regarding patient global assessment visual analog scales (PGA-VAS) and model disease states. The investigators found that vulnerable patients perceived difficulty with PGA-VAS and did not reliably rate a model disease state VAS. The authors suggest that these patients are potentially at risk for disease activity misclassification because of literacy and other barriers in completing VAS.

Smoking is associated with higher disease activity in rheumatoid arthritis: a longitudinal study controlling for time-varying covariates.
Prior studies around the relationship between smoking and rheumatoid arthritis (RA) disease activity have reported inconsistent findings, which may be ascribed to heterogeneous study designs or biases in statistical analyses. In this study, the investigators examined the association between smoking and RA outcomes using statistical methods that account for time-varying confounding and loss to followup. They found that smoking was associated with higher levels of disease activity in RA.

Listening to patients' voices: workarounds patients use to construct pain intensity ratings.
This study analyzed patients’ perspectives on constructing pain intensity ratings and workarounds used. Focus groups were conducted with thirty-one patients with osteoarthritis. Three emerging themes were found: 1) many factors affected patients’ perceptions and ratings of intensity, 2) patients used different approaches to evaluate pain, and 3) patients interpreted maximal response anchors differently. Activity items also helped patients to remember pain.

Assessment of a deep learning model based on electronic health record data to forecast clinical outcomes in patients with rheumatoid arthritis.
This study researched the use of artificial intelligence learning models to predict clinical outcomes in patients with rheumatoid arthritis (RA). Patients from a university hospital (UH) and a public safety-net hospital (SNH). The populations were quite different from each other. A total of 578 UH patients and 242 SNH patients were included in the study. Patients at the UH were seen more frequently than the SNH patients and were often prescribed high-class medications (63% vs. 28.9%). The model that was used showed a statistically random performance based on each patients’ most recent disease activity score.

Uptake and clinical utility of multibiomarker disease activity testing in the United States.
The purpose of this study was to examine the clinical utility of the multibiomarker disease activity (MBDA) test for rheumatoid arthritis management (RA) in routine care in the United States. Using Medicare data for 2011-15, researchers linked each patient with RA to their MBDA test result. Initiation of a biologic or Janus kinase inhibitor during the 6 months after MBDA testing was described. The researchers found that the MBDA score was associated with both biologic and Janus kinase inhibitor medication addition/switching and subsequent treatment outcomes.

Living in immigrant communities does not impact total knee arthroplasty outcomes: experience from a high-volume center in the United States.
The objective of this study was to assess the relationship of neighborhood immigrant proportion (IP) to preoperative and 2-year postoperative pain and function after elective total knee arthroplasty (TKA) using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Patients in a high-volume institutional TKA registry were analyzed retrospectively, and demographics, pre-op and 2-year post-op WOMAC pain and function scores, and addresses obtained. Patient-level variables were linked to Census Bureau tract data. Researchers conclude that patients living in high IP neighborhoods do not have worse pre-op or 2-year post-op pain and function outcomes after TKA compared to those living in lower IP neighborhoods.

Preferences for physical activity: a conjoint analysis involving people with chronic knee pain.
The goals of this study were to investigate individual preferences for physical activity attributes in adults with chronic knee pain, to identify clusters of individuals with similar preferences, and to identify whether these individuals differ by demographic or health characteristics. Researchers conducted an adaptive conjoint analysis (ACA) using the Potentially All Pairwise RanKings of all possible Alternatives (PAPRIKA) method to determine preference weights representing the relative importance of six physical activity attributes: health benefit, enjoyment, convenience, financial cost, effort, and time cost. The study sample included 146 participants. The authors conclude that patients with chronic knee pain have preferences for physical activities which are effectively distinguished by using ACA methods, and that adults with chronic knee pain, as clustered by their preferences, share distinguishing characteristics.

Patients less likely to lose weight following a knee replacement: results from the osteoarthritis initiative.
The purpose of this study was to examine weight change patterns preoperatively and postoperatively among overweight/obese knee replacement patients. Overweight and obese patients initially lost weight during the interval including knee replacement; however, they were less likely to lose more than 2.5% of their weight in the 1 to 2 years immediately after the surgery.

Ethnicity, cortisol, and experimental pain responses among persons with symptomatic knee osteoarthritis.
This study aimed to examine the relationship between cortisol and pain responses during a cold-pressor task (CPT) among African American (AA) and non-Hispanic White (NHW) adults with knee osteoarthritis (OA). Consistent with previous findings in young healthy adults, cold-pressor pain responses are related to pre-CPT cortisol concentrations in NHW persons with knee OA but not in their AA counterparts.

Functional gain and pain relief after total joint replacement according to obesity status.
The researchers examined the changes between preoperative and postoperative function and pain in a large representative U.S. cohort to determine if there was a relationship to obesity status. They found that six months after total joint replacement, severely or morbidly obese patients reported excellent pain relief and substantial functional gain that was similar to the findings in other patients.

Biologics or tofacitinib for people with rheumatoid arthritis naive to methotrexate: a systematic review and network meta-analysis.
The researchers performed a systematic review to compare the benefits and harms of biologics and small molecule tofacitinib versus comparator (methotrexate (MTX) and other disease-modifying antirheumatic drugs) in patients with rheumatoid arthritis (RA) who are naive to methotrexate. They concluded that in MTX-naive RA participants, there was moderate-quality evidence that, compared with MTX alone, biologics with MTX were associated with absolute and relative clinically meaningful benefits in three of the efficacy outcomes.

Using mHealth app to support treatment decision-making for knee arthritis: patient perspective.
The authors explored patient preferences on content and design of a mobile health app to facilitate daily symptom capture and summary feedback reporting, in order to inform treatment decisions, including use of total knee replacement surgery (TKR). The authors suggest that user input can inform the design and implementation of mHealth technology to meet patient needs for their treatment decisions. Patient priorities must be considered through patient-centered app design.

The clinical status and economic savings associated with remission among patients with rheumatoid arthritis: leveraging linked registry and claims data for synergistic insights.
Treat to target guidelines recommend achieving remission or low disease activity in rheumatoid arthritis (RA). However, the reduction in adverse events and costs associated with lower disease activity is unclear. This study found that leveraging the benefits of linking registry and administrative data together, lower disease activity in RA was associated with incrementally reduced risks of all-cause hospitalization, ED visits, mortality, and medical costs in a dose-dependent fashion.

Important patient characteristics differ prior to total knee arthroplasty and total hip arthroplasty between Switzerland and the United States.
The researchers compared preoperative patient and clinical characteristics from two large cohorts who underwent either total knee (TKA) or hip (THA) arthroplasty, one in Switzerland, the other in the US. They found substantial differences between US and Swiss cohorts in pre-operative patient characteristics and pain levels, which has potentially important implications for cross-cultural comparison of TKA/THA outcomes.
