Association of patient engagement strategies with utilisation and spending for musculoskeletal problems in the USA: a cross-sectional analysis of Medicare patients and physician practices.
This cross-sectional study assessed the association of physician practice-level adoption of patient engagement strategies (PES), such as shared decision-making and motivational interviewing, with utilization and spending. The cohort included primary and secondary patients in 2190 practices who receiving treatment for hip (39,336), knee (48,362), and lower-back (67,940) issues who were Medicare beneficiaries that were matched to the 2017-2018 National Survey of Healthcare Organizations and Systems. Outcome measures were total knee replacement (TKR), total hip replacement (THR), 1-2 level posterior lumbar fusion (LF), total annual spending, and components of total annual spending. Spending was significantly lower in some categories for practices with relatively higher PES adoption, but did not differ for other practices. The odds of receiving THR were higher in independent practices for patients attributed to practices with moderate PES compared to patients in practices with low PES.

Randomized controlled trial of patient education tools for patients with rheumatoid arthritis.
This randomized controlled trial compared results of patient education tools for patients with rheumatoid arthritis using a written booklet or a written booklet along with a newly developed video tool. Outcomes were measured immediately before and after review of the materials, and 3 and 6 months later. One-hundred eleven participants received an educational video and booklet and one-hundred ten a booklet alone. Mean age of participants was 50.8 years, mean disease duration 4.8 years, 85% were female, and 24% had limited health literacy levels. Both groups had improved outcomes up to 6 months after educational materials were delivered and used, with no statistically significant difference between the two groups. Patients receiving the video and booklet were more likely to rate the presentation as “excellent".

Socioeconomic disparities in functional status in a national sample of patients with rheumatoid arthritis.
This longitudinal study looked at the association of socioeconomic disparities and functional status in a national sample of patients with rheumatoid arthritis (RA). This study used a cohort from the American College of Rheumatology’s Rheumatology Informatics System for Effectiveness (RISE) registry from 2016 to 2018. Analyses included all adult patients with a confirmed RA diagnosis and at least 1 functional status (FS) score documented. The Area Deprivation Index (ADI), a zip code-based indicator of poverty, was used as a proxy for socioeconomic status (SES). The cohort included 83,965 patients, of which 77% were women and 72% were non-Hispanic White. Mean age was 63.4 years. The probability of functional decline was 14.1% in the highest SES quintile and 18.9% in the lowest SES quintile. By all measures FS score was worse at lower SES levels.

Clinical epidemiology and outcomes of pediatric musculoskeletal infections.
The objective of this study was to understand the epidemiology of acute hematogenous osteomyelitis and septic arthritis, including clinical and demographic features, microbiology, treatment approaches, treatment-associated complications, and outcomes. Musculoskeletal infections are challenging pediatric infections. The investigators concluded that S aureus remained the most common pathogen, with methicillin-resistant S aureus accounting for 25% of all cases. Concurrent acute hematogenous osteomyelitis/septic arthritis was associated with more severe disease and worse outcomes.

Discrimination experiences and depressive symptoms among African Americans with osteoarthritis enrolled in a pain coping skills training randomized controlled trial.
This study evaluated the interaction between discrimination experiences and depressive symptoms among African Americans with osteoarthritis enrolled in a pain coping skills training (PCST) randomized controlled trial. The authors evaluated the interactions for 164 participants in linear regression models predicting depressive symptoms. There was a significant interaction between personal discrimination and experimental condition on depressive symptoms. Discrimination was associated with depressive symptoms among the control group but not among those who received PCST.

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.

Risk of subsequent joint arthroplasty in contralateral or different joint after index shoulder, hip, or knee arthroplasty: association with index joint, demographics, and patient-specific factors.
The purpose of this study using HCUP data was to determine how demographic and other patient-specific factors are associated with the risk of subsequent joint replacement in the contralateral or a different joint following an index joint replacement for osteoarthritis. Results showed a relatively high risk of subsequent replacement of the contralateral joint and a relatively low risk of subsequent replacement of a different joint within 5 to 8 years after an index total hip arthroplasty, total knee arthroplasty, or total shoulder arthroplasty. Obesity was associated with a higher risk of subsequent replacement of the contralateral joint or a different joint.

Risk of malignancy associated with paediatric use of tumour necrosis factor inhibitors.
The objective of the study was to determine whether tumour necrosis factor inhibitor (TNFi) use is associated with an increased rate of incident malignancy compared with no TNFi use in the treatment of juvenile idiopathic arthritis (JIA), paediatric inflammatory bowel disease (pIBD) and paediatric plaque psoriasis (pPsO). The authors concluded that children diagnosed with JIA, pIBD and pPsO had an increased rate of malignancy compared with the general population, but treatment with TNFi did not appear to significantly further increase the risk compared with no TNFi use.

Does education level mitigate the effect of poverty on total knee arthroplasty outcomes?
The authors assessed the interaction between education and poverty on 2-year Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and function. They found that having no college was associated with worse pain and function at baseline and 2 years and that living in a poor neighborhood was associated with worse 2-year pain and function. There was a strong interaction between individual education and community poverty with WOMAC scores at 2 years. Patients without college living in poor communities had pain scores that were ~10 points worse than those with some college; in wealthy communities, college was associated with a 1-point difference in pain. Function was similar. The authors recommended further study on how education protects those in impoverished communities.

The epidemiology of wrist fractures in older men: the Osteoporotic Fractures in Men (MrOS) study.
The goal of this study was to calculate the frequency of and to identify risk factors for wrist fracture in the Osteoporotic Fractures in Men (MrOS) study. The researchers identified incident wrist fractures in men aged 65 or older. Potential risk factors included demographics, lifestyle, bone mineral density, selected medications, biomarkers, and physical function and performance measures. The researcher confirmed that fracture history and certain medications are predictors, and also identified novel predictors such as markers of kidney function and an inability to perform the grip strength test. They did not find associations with factors commonly associated with wrist and other osteoporosis fractures such as falls, diabetes, calcium and vitamin D intake, or alcohol intake.

Failure after modern total knee arthroplasty: a prospective study of 18,065 knees.
The investigators sought to determine the mechanism of failure among primary total knee arthroplasties (TKAs) performed at a single high-volume institution. They found that the most common reasons for failure within 2 years after TKA were infection and stiffness. They suggested that the study identified preoperative risk factors for failure of primary TKAs, which may be useful information for developing strategies to improve outcomes following TKA.

The impact of smoking on disease measures in rheumatoid arthritis: the need for appropriate adjustment of time-varying confounding.
In a recent publication, Quintana-Dunque et al. studied patients with early onset rheumatoid arthritis (RA) and showed that baseline smoking status was inversely associated with disease activity and disability at 36 months. This paper argues that the authors failed to highlight several limitations of study design and analysis, including time-varying confounding, which may have had a direct impact on results and corresponding conclusions.
