Relationship Between Clinician Language and the Success of Behavioral Weight Loss Interventions: A Mixed-Methods Cohort Study: Annals of Internal Medicine: Vol 176, No 11

Background: International guidelines recommend that primary care clinicians recognize obesity and offer treatment opportunistically, but there is little evidence on how clinicians can discuss weight and offer treatment in ways that are well received and effective. Objective: To examine relationships between language used in the clinical visit and patient weight loss. Design: Mixed-methods cohort study. Setting: 38 primary care clinics in England participating in the Brief Intervention for Weight Loss trial. Participants: 246 patients with obesity seen by 87 general practitioners randomly sampled from the intervention group of the randomized clinical trial. Measurements: Conversation analysis of recorded discussions between 246 patients with obesity and 87 clinicians regarding referral to a 12-week behavioral weight management program offered as part of the randomized clinical trial. Clinicians’ interactional approaches were identified and their association with patient weight loss at 12 months (primary outcome) was examined. Secondary outcomes included patients’ agreement to attend weight management, attendance, loss of 5% body weight, actions taken to lose weight, and postvisit satisfaction. Results: Three interactional approaches were identified on the basis of clinicians’ linguistic and paralinguistic practices: creating a sense of referrals as “good news” related to the opportunity of the referral (n = 62); “bad news,” focusing on the harms of obesity (n = 82); or neutral (n = 102). Outcome data were missing from 57 participants, so weighted analyses were done to adjust for missingness. Relative to neutral news, good news was associated with increased agreement to attend the program (adjusted risk difference, 0.25 [95% CI, 0.15 to 0.35]), increased attendance (adjusted risk difference, 0.45 [CI, 0.34 to 0.56]), and weight change (adjusted difference, −3.60 [CI, −6.58 to −0.62]). There was no evidence of differences in mean weight change comparing bad and neutral news, and no evidence of differences in patient satisfaction across all 3 approaches. Limitations: Data were audio only, so body language and nonverbal cues could not be assessed. There is potential for selection bias and residual confounding. Conclusion: When raising the topic of excess weight in clinical visits, presenting weight loss treatment as a positive opportunity is associated with greater uptake of treatment and greater weight loss.

High- Versus Low-Dose Exercise Therapy for Knee Osteoarthritis: A Randomized Controlled Multicenter Trial: Annals of Internal Medicine: Vol 176, No 2

Background: The benefits of exercise in patients with knee osteoarthritis are well documented, but the optimal exercise dose remains unknown. Objective: To compare high-dose versus low-dose exercise therapy with regard to knee function, pain, and quality of life (QoL) in patients with long-term symptomatic knee osteoarthritis. Design: A Swedish and Norwegian multicenter randomized controlled superiority trial with multiple follow-ups up to 12 months after the intervention. (ClinicalTrials.gov: NCT02024126) Setting: Primary health care facilities. Patients: 189 patients with diagnosed knee osteoarthritis and a history of pain and decreased knee function were assigned to high-dose therapy (n = 98; 11 exercises; 70 to 90 minutes) or low-dose therapy (n = 91; 5 exercises; 20 to 30 minutes). Intervention: Patient-tailored exercise programs according to the principles of medical exercise therapy. Global (aerobic), semiglobal (multisegmental), and local (joint-specific) exercises were performed 3 times a week for 12 weeks under supervision of a physiotherapist. Measurements: The Knee Injury and Osteoarthritis Outcome Score (KOOS) was measured biweekly during the 3-month intervention period and at 6 and 12 months after the intervention. The primary end point was the mean difference in KOOS scores between groups at the end of the intervention (3 months). Secondary outcomes included pain intensity and QoL. The proportion of patients with minimal clinically important changes in primary and secondary outcomes was compared between groups. Results: Both groups improved over time, but there were no benefits of high-dose therapy in most comparisons. One exception was the KOOS score for function in sports and recreation, where high-dose therapy was superior at the end of treatment and at 6-month follow-up. A small benefit in QoL at 6 and 12 months was also observed. Limitation: There was no control group that did not exercise. Conclusion: The results do not support the superiority of high-dose exercise over low-dose exercise for most outcomes. However, small benefits with high-dose exercise were found for knee function in sports and recreation and for QoL. Primary Funding Source: Swedish Rheumatic Fund.

Second-Line Chimeric Antigen Receptor T-Cell Therapy in Diffuse Large B-Cell Lymphoma: A Cost-Effectiveness Analysis: Annals of Internal Medicine: Vol 176, No 12

Background: First-line treatment of diffuse large B-cell lymphoma (DLBCL) achieves durable remission in approximately 60% of patients. In relapsed or refractory disease, only about 20% achieve durable remission with salvage chemoimmunotherapy and consolidative autologous stem cell transplantation (ASCT). The ZUMA-7 (axicabtagene ciloleucel [axi-cel]) and TRANSFORM (lisocabtagene maraleucel [liso-cel]) trials demonstrated superior event-free survival (and, in ZUMA-7, overall survival) in primary-refractory or early-relapsed (high-risk) DLBCL with chimeric antigen receptor T-cell therapy (CAR-T) compared with salvage chemoimmunotherapy and consolidative ASCT; however, list prices for CAR-T exceed $400 000 per infusion. Objective: To determine the cost-effectiveness of second-line CAR-T versus salvage chemoimmunotherapy and consolidative ASCT. Design: State-transition microsimulation model. Data Sources: ZUMA-7, TRANSFORM, other trials, and observational data. Target Population: “High-risk” patients with DLBCL. Time Horizon: Lifetime. Perspective: Health care sector. Intervention: Axi-cel or liso-cel versus ASCT. Outcome Measures: Incremental cost-effectiveness ratio (ICER) and incremental net monetary benefit (iNMB) in 2022 U.S. dollars per quality-adjusted life-year (QALY) for a willingness-to-pay (WTP) threshold of $200 000 per QALY. Results of Base-Case Analysis: The increase in median overall survival was 4 months for axi-cel and 1 month for liso-cel. For axi-cel, the ICER was $684 225 per QALY and the iNMB was −$107 642. For liso-cel, the ICER was $1 171 909 per QALY and the iNMB was −$102 477. Results of Sensitivity Analysis: To be cost-effective with a WTP of $200 000, the cost of CAR-T would have to be reduced to $321 123 for axi-cel and $313 730 for liso-cel. Implementation in high-risk patients would increase U.S. health care spending by approximately $6.8 billion over a 5-year period. Limitation: Differences in preinfusion bridging therapies precluded cross-trial comparisons. Conclusion: Neither second-line axi-cel nor liso-cel was cost-effective at a WTP of $200 000 per QALY. Clinical outcomes improved incrementally, but costs of CAR-T must be lowered substantially to enable cost-effectiveness. Primary Funding Source: No research-specific funding.

Outpatient Treatment of Confirmed COVID-19: Living, Rapid Practice Points From the American College of Physicians (Version 1)

An update is available for this article. Description: Strategies to manage COVID-19 in the outpatient setting continue to evolve as new data emerge on SARS-CoV-2 variants and the availability of newer treatments. The Scientific Medical Policy Committee (SMPC) of the American College of Physicians (ACP) developed these living, rapid practice points to summarize the best available evidence on the treatment of adults with confirmed COVID-19 in an outpatient setting. These practice points do not evaluate COVID-19 treatments in the inpatient setting or adjunctive COVID-19 treatments in the outpatient setting. Methods: The SMPC developed these living, rapid practice points on the basis of a living, rapid review done by the ACP Center for Evidence Reviews at Cochrane Austria at the University for Continuing Education Krems (Danube University Krems). The SMPC will maintain these practice points as living by monitoring and assessing the impact of new evidence. Practice Point 1: Consider molnupiravir to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting who are within 5 to 7 days of the onset of symptoms and at high risk for progressing to severe disease. Practice Point 2: Consider nirmatrelvir–ritonavir combination therapy to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting who are within 5 days of the onset of symptoms and at high risk for progressing to severe disease. Practice Point 3: Consider remdesivir to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting who are within 7 days of the onset of symptoms and at high risk for progressing to severe disease. Practice Point 4: Do not use azithromycin to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting. Practice Point 5: Do not use chloroquine or hydroxychloroquine to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting. Practice Point 6: Do not use ivermectin to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting. Practice Point 7: Do not use nitazoxanide to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting. Practice Point 8: Do not use lopinavir–ritonavir combination therapy to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting. Practice Point 9: Do not use casirivimab–imdevimab combination therapy to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting unless it is considered effective against a SARS-CoV-2 variant or subvariant locally in circulation. Practice Point 10: Do not use regdanvimab to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting unless it is considered effective against a SARS-CoV-2 variant or subvariant locally in circulation. Practice Point 11: Do not use sotrovimab to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting unless it is considered effective against a SARS-CoV-2 variant or subvariant locally in circulation. Practice Point 12: Do not use convalescent plasma to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting. Practice Point 13: Do not use ciclesonide to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting. Practice Point 14: Do not use fluvoxamine to treat patients with confirmed mild to moderate COVID-19 in the outpatient setting.
