RESUMEN
BACKGROUND: Definitions of long COVID are evolving, and optimal models of care are uncertain. PURPOSE: To perform a scoping review on definitions of long COVID and provide an overview of care models, including a proposed framework to describe and distinguish models. DATA SOURCES: English-language articles from Ovid MEDLINE, PsycINFO, the Cochrane Library, SocINDEX, Scopus, Embase, and CINAHL published between January 2021 and November 2023; gray literature; and discussions with 18 key informants. STUDY SELECTION: Publications describing long COVID definitions or models of care, supplemented by models described by key informants. DATA EXTRACTION: Data were extracted by one reviewer and verified for accuracy by another reviewer. DATA SYNTHESIS: Of 1960 screened citations, 38 were included. Five clinical definitions of long COVID varied with regard to timing since symptom onset and the minimum duration required for diagnosis; 1 additional definition was symptom score-based. Forty-nine long COVID care models were informed by 5 key principles: a core "lead" team, multidisciplinary expertise, comprehensive access to diagnostic and therapeutic services, a patient-centered approach, and providing capacity to meet demand. Seven characteristics provided a framework for distinguishing models: home department or clinical setting, clinical lead, collocation of other specialties, primary care role, population managed, use of teleservices, and whether the model was practice- or systems-based. Using this framework, 10 representative practice-based and 3 systems-based models of care were identified. LIMITATIONS: Published literature often lacked key model details, data were insufficient to assess model outcomes, and there was overlap between and variability within models. CONCLUSION: Definitions of long COVID and care models are evolving. Research is needed to optimize models and evaluate outcomes of different models.

BACKGROUND: Contemporary data are needed about the utility of cannabinoids in chronic pain. PURPOSE: To evaluate the benefits and harms of cannabinoids for chronic pain. DATA SOURCES: Ovid MEDLINE, PsycINFO, EMBASE, the Cochrane Library, and Scopus to January 2022. STUDY SELECTION: English-language, randomized, placebo-controlled trials and cohort studies (≥1 month duration) of cannabinoids for chronic pain. DATA EXTRACTION: Data abstraction, risk of bias, and strength of evidence assessments were dually reviewed. Cannabinoids were categorized by THC-to-CBD ratio (high, comparable, or low) and source (synthetic, extract or purified, or whole plant). DATA SYNTHESIS: Eighteen randomized, placebo-controlled trials (n = 1740) and 7 cohort studies (n = 13 095) assessed cannabinoids. Studies were primarily short term (1 to 6 months); 56% enrolled patients with neuropathic pain, with 3% to 89% female patients. Synthetic products with high THC-to-CBD ratios (>98% THC) may be associated with moderate improvement in pain severity and response (≥30% improvement) and an increased risk for sedation and are probably associated with a large increased risk for dizziness. Extracted products with high THC-to-CBD ratios (range, 3:1 to 47:1) may be associated with large increased risk for study withdrawal due to adverse events and dizziness. Sublingual spray with comparable THC-to-CBD ratio (1.1:1) probably is associated with small improvement in pain severity and overall function and may be associated with large increased risk for dizziness and sedation and moderate increased risk for nausea. Evidence for other products and outcomes, including longer-term harms, were not reported or were insufficient. LIMITATION: Variation in interventions; lack of study details, including unclear availability in the United States; and inadequate evidence for some products. CONCLUSION: Oral, synthetic cannabis products with high THC-to-CBD ratios and sublingual, extracted cannabis products with comparable THC-to-CBD ratios may be associated with short-term improvements in chronic pain and increased risk for dizziness and sedation. Studies are needed on long-term outcomes and further evaluation of product formulation effects.

BACKGROUND: Telehealth strategies to supplement or replace in-person maternity care may affect maternal health outcomes. PURPOSE: To conduct a rapid review of the effectiveness and harms of telehealth strategies for maternal health care given the recent expansion of telehealth arising from the COVID-19 pandemic, and to produce an evidence map. DATA SOURCES: Systematic searches of MEDLINE, the Cochrane Library, CINAHL, Embase, and Scopus for English-language studies (January 2015 to April 2022). STUDY SELECTION: Randomized controlled trials (RCTs) and observational studies of maternal care telehealth strategies versus usual care. DATA EXTRACTION: Dual data extraction and risk-of-bias assessment of studies, with disagreements resolved through consensus. DATA SYNTHESIS: 28 RCTs and 14 observational studies (n = 44 894) were included. Maternal telehealth interventions supplemented in-person care for most studies of mental health and diabetes during pregnancy, primarily resulting in similar, and sometimes better, clinical and patient-reported outcomes versus usual care. Supplementing in-person mental health care with phone- or web-based platforms or mobile applications resulted in similar or better mental health outcomes versus in-person care. A reduced-visit prenatal care schedule using telehealth to replace in-person general maternity care for low-risk pregnancies resulted in similar clinical outcomes and higher patient satisfaction versus usual care. Overall, telehealth strategies were heterogeneous and resulted in similar obstetric and patient satisfaction outcomes. Few studies addressed disparities, health equity, or harms. LIMITATIONS: Interventions varied, and evidence was inadequate for some clinical outcomes. CONCLUSION: Replacing or supplementing in-person maternal care with telehealth generally results in similar, and sometimes better, clinical outcomes and patient satisfaction compared with in-person care. The effect on access to care, health equity, and harms is unclear. PRIMARY FUNDING SOURCE: Patient-Centered Outcomes Research Institute. (PROSPERO: CRD42021276347).

Importance: A 2019 review for the US Preventive Services Task Force (USPSTF) found oral preexposure prophylaxis (PrEP) associated with decreased HIV infection risk vs placebo or no PrEP in adults at increased HIV acquisition risk. Newer PrEP regimens are available. Objective: To update the 2019 review on PrEP, to inform the USPSTF. Data Sources: Ovid MEDLINE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and Embase (January 2018 to May 16, 2022); surveillance through March 24, 2023. Study Selection: Randomized clinical trials of PrEP vs placebo or no PrEP or newer vs older PrEP regimens and diagnostic accuracy studies of instruments for predicting incident HIV infection. Data Extraction and Synthesis: Dual review of titles and abstracts, full-text articles, study quality, and data abstraction. Data were pooled using the DerSimonian and Laird random-effects model. Main Outcomes and Measures: HIV acquisition, mortality, and harms; and diagnostic test accuracy. Results: Thirty-two studies were included in the review (20 randomized clinical trials [N = 36â¯543] and 12 studies of diagnostic accuracy [N = 5â¯544â¯500]). Eleven trials in the 2019 review found oral PrEP associated with decreased HIV infection risk vs placebo or no PrEP (n = 18â¯172; relative risk [RR], 0.46 [95% CI, 0.33-0.66]). Higher adherence was associated with greater efficacy. One new trial (n = 5335) found oral tenofovir alafenamide/emtricitabine (TAF/FTC) to be noninferior to tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) in men who have sex with men (RR, 0.47 [95% CI, 0.19-1.14]). Two new trials found long-acting injectable cabotegravir associated with decreased risk of HIV infection vs oral TDF/FTC (RR, 0.33 [95% CI, 0.18-0.62] in cisgender men who have sex with men and transgender women [n = 4490] and RR, 0.11 [95% CI, 0.04-0.31] in cisgender women [n = 3178]). Discrimination of instruments for predicting incident HIV infection was moderate in men who have sex with men (5 studies; n = 25â¯488) and moderate to high in general populations of persons without HIV (2 studies; n = 5â¯477â¯291). Conclusions and Relevance: In adults at increased HIV acquisition risk, oral PrEP was associated with decreased risk of acquiring HIV infection compared with placebo or no PrEP. Oral TAF/FTC was noninferior to oral TDF/FTC, and injectable cabotegravir reduced the risk of HIV infection compared with oral TDF/FTC in the populations studied.

Importance: Dental caries is common in children and adolescents aged 5 to 17 years and potentially amenable to primary care screening and prevention. Objective: To systematically review the evidence on primary care screening and prevention of dental caries in children and adolescents aged 5 to 17 years to inform the US Preventive Services Task Force. Data Sources: MEDLINE, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews (to October 3, 2022); surveillance through July 21, 2023. Study Selection: Diagnostic accuracy of primary care screening instruments and oral examination; randomized and nonrandomized trials of screening and preventive interventions and systematic reviews of such studies; cohort studies on primary care oral health screening and preventive intervention harms. Data Extraction and Synthesis: One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. Random-effects meta-analysis was performed for fluoride supplements and xylitol; for other preventive interventions, pooled estimates were used from good-quality systematic reviews. Main Outcomes and Measures: Dental caries, morbidity, functional status, quality of life, harms; diagnostic test accuracy. Results: Three systematic reviews (total 20â¯684 participants) and 19 randomized clinical trials, 3 nonrandomized trials, and 1 observational study (total 15â¯026 participants) were included. No study compared screening vs no screening. When administered by dental professionals or in school settings, fluoride supplements compared with placebo or no intervention were associated with decreased change from baseline in the number of decayed, missing, or filled permanent teeth (DMFT index) or decayed or filled permanent teeth (DFT index) (mean difference, -0.73 [95% CI, -1.30 to -0.19]) at 1.5 to 3 years (6 trials; n = 1395). Fluoride gels were associated with a DMFT- or DFT-prevented fraction of 0.18 (95% CI, 0.09-0.27) at outcomes closest to 3 years (4 trials; n = 1525), fluoride varnish was associated with a DMFT- or DFT-prevented fraction of 0.44 (95% CI, 0.11-0.76) at 1 to 4.5 years (5 trials; n = 3902), and resin-based sealants were associated with decreased risk of carious first molars (odds ratio, 0.21 [95% CI, 0.16-0.28]) at 48 to 54 months (4 trials; n = 440). No trial evaluated primary care counseling or dental referral. Evidence on screening accuracy, silver diamine fluoride, xylitol, and harms was very limited, although serious harms were not reported. Conclusions and Relevance: Administration of fluoride supplements, fluoride gels, varnish, and sealants in dental or school settings improved caries outcomes. Research is needed on the effectiveness of oral health preventive interventions in primary care settings and to determine the benefits and harms of screening.

Importance: Dental caries and periodontal disease are common adult oral health conditions and potentially amenable to primary care screening and prevention. Objective: To systematically review the evidence on primary care screening and prevention of dental caries and periodontal disease in adults to inform the US Preventive Services Task Force. Data Sources: MEDLINE, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews (to October 3, 2022); surveillance through July 21, 2023. Study Selection: Diagnostic accuracy studies of primary care screening instruments and oral examination; randomized and nonrandomized trials of screening and preventive interventions; cohort studies on primary care oral health screening and preventive intervention harms. Data Extraction and Synthesis: One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. Diagnostic accuracy data were pooled using a bivariate mixed-effects binary regression model. Main Outcomes and Measures: Dental caries, periodontal disease, morbidity, quality of life, harms; and diagnostic test accuracy. Results: Five randomized clinical trials, 5 nonrandomized trials, and 6 observational studies (total 3300 participants) were included. One poor-quality trial (n = 477) found no difference between oral health screening during pregnancy vs no screening in caries, periodontal disease, or birth outcomes. One study (n = 86) found oral health examination by 2 primary care clinicians associated with low sensitivity (0.42 and 0.56) and high specificity (0.84 and 0.87) for periodontal disease and with variable sensitivity (0.33 and 0.83) and high specificity (0.80 and 0.93) for dental caries. Four studies (n = 965) found screening questionnaires associated with a pooled sensitivity of 0.72 (95% CI, 0.57-0.83) and specificity of 0.74 (95% CI, 0.66-0.82) for periodontal disease. For preventive interventions no study evaluated primary care counseling or dental referral, and evidence from 2 poor-quality trials (n = 178) of sealants, and 1 fair-quality and 4 poor-quality trials (n = 971) of topical fluorides, was insufficient. Three fair-quality trials (n = 590) of persons with mean age 72 to 80 years found silver diamine fluoride solution associated with fewer new root caries lesions or fillings vs placebo (mean reduction, -0.33 to -1.3) and decreased likelihood of new root caries lesion (2 trials; adjusted odds ratio, 0.4 [95% CI, 0.3-0.7]). No trial evaluated primary care-administered preventive interventions. Conclusions and Relevance: Screening questionnaires were associated with moderate diagnostic accuracy for periodontal disease. Research is needed to determine benefits and harms of oral health primary care screening and preventive interventions.

Importance: A 2016 review for the US Preventive Services Task Force (USPSTF) found use of statins for primary prevention of cardiovascular disease (CVD) was associated with reduced mortality and cardiovascular outcomes. Objective: To update the 2016 review on statins for primary prevention of CVD to inform the USPSTF. Data Sources: Ovid MEDLINE, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews (to November 2021); surveillance through May 20, 2022. Study Selection: Randomized clinical trials on statins vs placebo or no statin and statin intensity in adults without prior cardiovascular events; large cohort studies on harms. Data Extraction and Synthesis: One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. Main Outcomes and Measures: All-cause and cardiovascular mortality, myocardial infarction, stroke, composite cardiovascular outcomes, and adverse events. Results: Twenty-six studies were included: 22 trials (N = 90â¯624) with 6 months to 6 years of follow-up compared statins vs placebo or no statin, 1 trial (n = 5144) compared statin intensities, and 3 observational studies (n = 417â¯523) reported harms. Statins were significantly associated with decreased risk of all-cause mortality (risk ratio [RR], 0.92 [95% CI, 0.87 to 0.98]; absolute risk difference [ARD], -0.35% [95% CI, -0.57% to -0.14%]), stroke (RR, 0.78 [95% CI, 0.68 to 0.90]; ARD, -0.39% [95% CI, -0.54% to -0.25%]), myocardial infarction (RR, 0.67 [95% CI, 0.60 to 0.75]; ARD, -0.85% [95% CI, -1.22% to -0.47%]), and composite cardiovascular outcomes (RR, 0.72 [95% CI, 0.64 to 0.81]; ARD, -1.28% [95% CI, -1.61% to -0.95%]); the association with cardiovascular mortality was not statistically significant (RR, 0.91 [95% CI, 0.81 to 1.02]; ARD, -0.13%). Relative benefits were consistent in groups defined by demographic and clinical characteristics, although data for persons older than 75 years were sparse. Statin therapy was not significantly associated with increased risk of serious adverse events (RR, 0.97 [95% CI, 0.93 to 1.01]), myalgias (RR, 0.98 [95% CI, 0.86 to 1.11]), or elevated alanine aminotransferase level (RR, 0.94 [95% CI, 0.78 to 1.13]). Statin therapy was not significantly associated with increased diabetes risk overall (RR, 1.04 [95% CI, 0.92 to 1.19]), although 1 trial found high-intensity statin therapy was significantly associated with increased risk (RR, 1.25 [95% CI, 1.05 to 1.49]). Otherwise, there were no clear differences in outcomes based on statin intensity. Conclusions and Relevance: In adults at increased CVD risk but without prior CVD events, statin therapy for primary prevention of CVD was associated with reduced risk of all-cause mortality and CVD events. Benefits of statin therapy appear to be present across diverse demographic and clinical populations, with consistent relative benefits in groups defined by demographic and clinical characteristics.
