The Effect of Social Isolation on 1-Year Outcomes After Surgical Repair of Low-Energy Hip Fracture

OBJECTIVES

To evaluate whether social isolation or loneliness is associated with outcomes 1 year after low-energy hip fracture.

METHODS

DESIGN

Prospective inception cohort study.

SETTING

Academic level I trauma center.

PATIENT SELECTION CRITERIA

Participants were 65 years or older and enrolled 2-4 days after surgery for a first low-energy hip fracture. Exclusion criteria were bilateral or periprosthetic hip fracture, previous hip fracture, non-English speaking, international address, active cancer, stage 4 cancer in the past 5 years, radiation to the hip region, and cognitive impairment. Participants were followed longitudinally for 1 year.

OUTCOME MEASURES AND COMPARISONS

The patient-reported outcomes measurement information system (PROMIS)-29 was elicited 2-4 days postoperatively and 1 year later. Patient-reported risk factors included the Lubben Social Networks Scale and the University of California, Los Angeles Loneliness Scale, which were compared with the lower extremity activity scale and PROMIS-29 domains.

RESULTS

Three hundred and twenty-five patients were enrolled. Participants had a median age of 81.7 years, were 70.9% female, and were 85.9% White. In total, 31.6% of patients were socially isolated at the time of fracture. At 1 year, 222 of the 291 subjects who were confirmed alive at 1 year provided data. Multivariable linear models were performed separately for each outcome, including lower extremity activity scale and PROMIS-29 domains. Controlling for age, sex, education, and body mass index, those who were socially isolated at the time of fracture had worse PROMIS-29 function (β = -3.83; P = 0.02) and ability to participate in social roles (β = -4.17; P = 0.01) at 1 year. Secondary analyses found that prefracture loneliness was associated with clinically meaningfully worse function, anxiety, depression, fatigue, sleep, pain, and ability to participate in social roles at 1 year (all P < 0.01).

CONCLUSIONS

Prefracture social isolation was associated with worse outcomes 1 year after surgical repair of low-energy hip fracture. These data suggest loneliness may be more strongly associated with important patient-centric metrics than prefracture social isolation. Given the dearth of modifiable risk factors in this population, future studies are needed to evaluate whether improving social connections could affect outcomes in this rapidly growing demographic.

An Instrument for Measuring Critical Appraisal Self-Efficacy in Rheumatology Trainees

OBJECTIVE

Self-efficacy, the internal belief that one can perform a specific task successfully, influences behavior. To promote critical appraisal of medical literature, rheumatology training programs should foster both competence and self-efficacy for critical appraisal. This study aimed to investigate whether select items from the Clinical Research Appraisal Inventory (CRAI), an instrument measuring clinical research self-efficacy, could be used to measure critical appraisal self-efficacy (CASE).

METHODS

One hundred twenty-five trainees from 33 rheumatology programs were sent a questionnaire that included two sections of the CRAI. Six CRAI items relevant to CASE were identified a priori; responses generated a CASE score (total score range 0-10; higher = greater confidence in one's ability to perform a specific task successfully). CASE scores' internal structure and relation to domain-concordant variables were analyzed.

RESULTS

Questionnaires were completed by 112 of 125 (89.6%) trainees. CASE scores ranged from 0.5 to 8.2. The six CRAI items contributing to the CASE score demonstrated high internal consistency (Cronbach's α = 0.95) and unidimensionality. Criterion validity was supported by the findings that participants with higher CASE scores rated their epidemiology and biostatistics understanding higher than that of peers (P < 0.0001) and were more likely to report referring to studies to answer clinical questions (odds ratio 2.47, 95% confidence interval 1.41-4.33; P = 0.002). The correlation of CASE scores with percentage of questions answered correctly was only moderate, supporting discriminant validity.

CONCLUSION

The six-item CASE instrument demonstrated content validity, internal consistency, discriminative capability, and criterion validity, including correlation with self-reported behavior, supporting its potential as a useful measure of critical appraisal self-efficacy.

Pregnancy and Rheumatic Disease: Experience at a Single Center in New York City During the COVID-19 Pandemic

OBJECTIVE

The present study was undertaken to evaluate the pregnancy experiences of women receiving care in the division of rheumatology at a major academic center in New York City during the COVID-19 pandemic.

METHODS

A web-based COVID-19 survey was emailed to 26,045 patients who were followed in the division of rheumatology at a single center in New York City. Women ages 18-50 years were asked about their pregnancy. We compared the COVID-19 experience between pregnant and nonpregnant women and also explored the impact of the pandemic on prenatal care and perinatal outcomes.

RESULTS

Among 7,094 of the 26,045 respondents, 1,547 were women ages 18-50 years, with 61 (4%) reporting being pregnant during the pandemic. The prevalence of self-reported COVID-19 was similar in pregnant and nonpregnant women (8% versus 9%, respectively; P = 0.76). Among women with COVID-19, pregnant women had a shorter duration of symptoms (P < 0.01) and were more likely to experience loss of smell or taste (P = 0.02) than nonpregnant women. Approximately three-fourths of women had a systemic rheumatic disease, with no differences when stratified by pregnancy or COVID-19 status. In all, 67% of pregnant women noted changes to prenatal care during the pandemic, and 23% of postpartum women stated that the pandemic affected delivery.

CONCLUSION

Among women followed in the division of rheumatology at a major center in New York City, pregnancy was not associated with increased self-reported COVID-19. Pregnancy was associated with a shorter duration of COVID-19 symptoms and a higher prevalence of loss of smell or taste. The COVID-19 pandemic impacted prenatal care for the majority of pregnant patients.

Learning to Critically Appraise Rheumatic Disease Literature: Educational Opportunities During Training and into Practice

To provide optimal patient care, rheumatologists must be equipped and motivated to critically appraise the literature. The conceptual frameworks Retrieval Enhanced Learning, Self-Determination Theory, and Communities of Practice can inform the design of educational approaches to promote critical appraisal in practice. HSS CLASS-Rheum® is a learning tool that can be used to help rheumatologists learn skills for critical appraisal through retrieval practice. Combining retrieval practice with opportunities for connection through Peer Instruction, journal clubs, and other forums can help support engagement and internalization of motivation, promoting persistence with critical appraisal in practice.
