ImportanceSARS-CoV-2 infection is associated with persistent, relapsing, or new symptoms or other health effects occurring after acute infection, termed postacute sequelae of SARS-CoV-2 infection (PASC), also known as long COVID. Characterizing PASC requires analysis of prospectively and uniformly collected data from diverse uninfected and infected individuals.ObjectiveTo develop a definition of PASC using self-reported symptoms and describe PASC frequencies across cohorts, vaccination status, and number of infections.Design, Setting, and ParticipantsProspective observational cohort study of adults with and without SARS-CoV-2 infection at 85 enrolling sites (hospitals, health centers, community organizations) located in 33 states plus Washington, DC, and Puerto Rico. Participants who were enrolled in the RECOVER adult cohort before April 10, 2023, completed a symptom survey 6 months or more after acute symptom onset or test date. Selection included population-based, volunteer, and convenience sampling.ExposureSARS-CoV-2 infection.Main Outcomes and MeasuresPASC and 44 participant-reported symptoms (with severity thresholds).ResultsA total of 9764 participants (89% SARS-CoV-2 infected; 71% female; 16% Hispanic/Latino; 15% non-Hispanic Black; median age, 47 years [IQR, 35-60]) met selection criteria. Adjusted odds ratios were 1.5 or greater (infected vs uninfected participants) for 37 symptoms. Symptoms contributing to PASC score included postexertional malaise, fatigue, brain fog, dizziness, gastrointestinal symptoms, palpitations, changes in sexual desire or capacity, loss of or change in smell or taste, thirst, chronic cough, chest pain, and abnormal movements. Among 2231 participants first infected on or after December 1, 2021, and enrolled within 30 days of infection, 224 (10% [95% CI, 8.8%-11%]) were PASC positive at 6 months.Conclusions and RelevanceA definition of PASC was developed based on symptoms in a prospective cohort study. As a first step to providing a framework for other investigations, iterative refinement that further incorporates other clinical features is needed to support actionable definitions of PASC.

BACKGROUND Re-hospitalization after discharge for acute decompensated heart failure is a common problem. Low-socioeconomic urban patients suffer high rates of re-hospitalization and often over-utilize the emergency department (ED) for their care. We hypothesized that early consultation with a cardiologist in the ED can reduce re-hospitalization and health care costs for low-socioeconomic urban patients with acute decompensated heart failure. METHODS There were 392 patients treated at our center for acute decompensated heart failure who received standardized education and follow-up. Patients who returned to the ED received early consultation with a cardiologist; 392 patients who received usual care served as controls. Thirty- and 90-day re-hospitalization, ED re-visits, heart failure symptoms, mortality, and health care costs were recorded. RESULTS Despite guideline-based education and follow-up, the rate of ED re-visits was not different between the groups. However, the rate of re-hospitalization was significantly lower in patients receiving the intervention compared with controls (odds ratio 0.592), driven by a reduction in the risk of readmission from the ED (0.56 vs 0.79, respectively). Patients receiving the intervention accumulated 14% fewer re-hospitalized days than controls and 57% lower 30-day total health care cost. Despite the reduction in health care resource consumption, mortality was unchanged. After accounting for the total cost of intervention delivery, the health care cost savings was substantially greater than the cost of intervention delivery. CONCLUSION Early consultation with a cardiologist in the ED as an adjunct to guideline-based follow-up is associated with reduced re-hospitalization and health care cost for low-socioeconomic urban patients with acute decompensated heart failure.

Background: Low-socioeconomic, urban, minority patients with heart failure (HF) often have unique barriers to care. Community health workers (CHWs) are specially trained laypeople who serve as liaisons between underserved communities and the health system. It is not known whether CHWs improve outcomes in low-socioeconomic, urban, minority patients with HF. Hypothesis: CHWs reduce rehospitalizations, emergency department (ED) visits, and healthcare costs for low-socioeconomic urban patients with HF. Methods: Patients admitted with acute decompensated HF were assigned to receive weekly visits by CHW after discharge. Patients were propensity score matched with controls who received usual care. HF-related rehospitalizations, ED visits, and inpatient costs were compared for 12 months following index admission versus the same period before. Results: Twenty-eight patients who received weekly visits from a CHW for 12 months after discharge were matched with 28 control patients who did not receive CHWs. Patients who received a CHW had a 75% decrease in HF-related ED visits (0.71 vs. 0.18 visits per patient, P < 0.001), an 89% decrease in HF-related readmissions (0.64 vs. 0.07 admissions per patient, P < 0.005), and a significant decrease in inpatient cost for HF-related visits. In controls receiving usual care, there was no significant change in hospitalizations, ED visits, or costs. Conclusions: In conclusion, CHWs are associated with reduced rehospitalizations, ED visits, and inpatient costs in low-socioeconomic, urban, minority patients with HF. CHWs may be a cost-effective method to reduce health care utilization and improve outcomes for this population.
