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.
Topic Hospital-acquired pneumonia commonly develops after 48 hours of hospitalization and can be divided into non–ventilator-acquired and ventilator-acquired pneumonia. Prevention of non–ventilator-acquired pneumonia requires a multimodal approach. Implementation of oral care bundles can reduce the incidence of ventilator-acquired pneumonia, but the literature on oral care in other populations is limited. Clinical Relevance Use of noninvasive ventilation is increasing owing to positive outcomes. The incidence of non–ventilator-acquired pneumonia is higher in patients receiving noninvasive ventilation than in the general hospitalized population but remains lower than that of ventilator-acquired pneumonia. Non–ventilator-acquired pneumonia increases mortality risk and hospital length of stay. Purpose To familiarize nurses with the evidence regarding oral care in critically ill patients requiring noninvasive ventilation. Content Covered No standard of oral care exists for patients requiring noninvasive ventilation owing to variation in study findings, definitions, and methods. Oral care decreases the risk of hospital-acquired pneumonia and improves comfort. Nurses perform oral care less often for nonintubated patients, as it is perceived as primarily a comfort measure. The potential risks of oral care for patients receiving noninvasive ventilation have not been explored. Further research is warranted before this practice can be fully implemented. Conclusion Oral care is a common preventive measure for non–ventilator-acquired pneumonia and may improve comfort. Adherence to oral care is lower for patients not receiving mechanical ventilation. Further research is needed to identify a standard of care for oral hygiene for patients receiving noninvasive ventilation and assess the risk of adverse events.
Background Extubation failure is the reintubation of patients meeting criteria for weaning from mechanical ventilation. Extubation failure is correlated with mortality, prolonged mechanical ventilation, and longer hospital stays. Noninvasive ventilation or high-flow nasal cannula oxygen therapy after extubation is recommended to prevent extubation failure in high-risk patients. Local Problem The extubation failure rate is unknown. Prophylactic measures (noninvasive ventilation or high-flow nasal cannula) after extubation are not commonly used and vary among clinicians. The objective was to assess extubation planning readiness by determining extubation failure rate, identifying high-risk patients, and determining prophylactic measure compliance. Methods A quality improvement initiative included an evidence-based extubation failure risk assessment that identified high-risk patients and determined prophylactic measure compliance. A 2-year retrospective medical record review was used to determine baseline patient characteristics and extubation failure rate. Results Extubation failure rate within the retrospective cohort was 13 of 146 patients (8.9%). Extubation failure did not correlate with previously identified risk factors; however, 150 identified patients were excluded from analysis. During risk assessment integration, the extubation failure rate was 3 of 37 patients (8.1%) despite identifying 24 high-risk patients (65%). Few high-risk patients received prophylactic measures (noninvasive ventilation, 17%; high-flow nasal cannula, 12%). Conclusions Extubation failure should be routinely measured because of its effects on patient outcomes. This project reveals the multifactorial nature of extubation failure. Further research is needed to assess patients’ risk and account for acute conditions. This project used best practice guidelines for routine patient care and added transparency to a previously unmeasured event.
Compensatory mechanisms involving the endocrine system can mask dysfunction, which can cause providers to miss signs of altered endocrine function. Experienced clinical nurses should use critical thinking and assessment skills to monitor patients for abnormal signs and symptoms.
Topic/Clinical Relevance The use of noninvasive respiratory support, including noninvasive ventilation and high-flow nasal cannula therapy, has increased over the years. Failure of noninvasive respiratory support, defined as the need for invasive mechanical ventilation, increases the mortality rate. Purpose To familiarize critical care nurses with available risk stratification assessments and identify common concepts and limitations. Content Covered Few risk stratification assessments are available to identify patients at risk of failure of noninvasive respiratory support. Although many studies have analyzed risk, substantial variation in study design, definitions, terminology, and outcomes have led to a wide range of findings, making clinical application difficult. Further study is needed to broaden known assessments to general patient populations, determine diagnostic accuracy during critical periods, and analyze noninvasive ventilation and high-flow nasal cannula therapy. Risk stratification could allow for better implementation of preventive strategies and patient education. Conclusion Future research opportunities include improving study design for risk stratification and implementing preventive strategies for patients requiring noninvasive respiratory support. Clinically, risk stratification can provide an opportunity to share knowledge and facilitate conversations with patients and families.
