Purpose: Despite its routine use to monitor patients with lung cancer (LC), real-world evaluations of the impact of computed tomography (CT) surveillance on overall survival (OS) have been inconsistent. A major confounder is the absence of imaging indications because patients undergo CT scans for purposes beyond surveillance, like symptom evaluations (eg, cough) linked to poor survival. We propose a novel natural language processing model to predict CT imaging indications (surveillance others).

Background: While research on health-related social needs (HRSNs) has expanded, important gaps remain in understanding associations between HRSN and healthcare cost, especially across general populations of patients with broad-ranging medical and social needs.

Objective: To examine the association between HRSN and healthcare cost in a large, diverse, insured population.

Design: In this cross-sectional study, we evaluated cost differences between patients with different HRSN levels using survey-weighted multivariable generalized linear models.

Lung cancer screening (LCS) has evolved over the past decade with research advances and clinical experience helping to define target populations for screening, to improve lung nodule detection and management, and to identify structural components of programs that improve the quality of screening delivery. The 2015 American College of Chest Physicians and American Thoracic Society Policy Statement, "Components Necessary for High-Quality Lung Cancer Screening," identified 9 essential components for high-quality LCS. Ten years later, optimizing the balance between the benefits and harms of LCS and ensuring equitable screening among all population groups remain fundamental objectives.

Background: Optimal surveillance strategies for patients with small pulmonary nodules are uncertain. The Watch the Spot Trial, a large, cluster-randomized, pragmatic clinical trial, compared less- versus more-intensive strategies for surveillance of patients with incidental or screening-detected nodules ≤15 mm.

Methods: We describe between-site variation in methods to identify and enroll patients with small nodules; we used standard measures to describe baseline characteristics of participants and nodules.

Background: Recent updates to national guidelines recommend primary human papillomavirus (HPV) screening for routine cervical cancer screening alongside previously recommended screening options. However, limited guidance exists for implementation approaches that best facilitate cancer screening practice substitution and achieve optimal stakeholder-centered outcomes. We compared "centrally-administered + locally-tailored" (here after referred to as locally-tailored) vs.

Background: Timeliness of colposcopy follow-up after primary human papillomavirus screening has not been well examined.

Objective: We evaluated time to colposcopy follow-up among women with an abnormal primary human papillomavirus screening result overall and by human papillomavirus genotype, triage cytology results, race/ethnicity, and neighborhood deprivation index.

Study Design: Women aged 30 to 65 years who received primary human papillomavirus screening at Kaiser Permanente Southern California from July 15, 2020, to December 31, 2021 and had screening results that required colposcopy follow-up were identified.

Importance: Screening for lung cancer with low-dose computed tomography (LDCT) has been shown to reduce lung cancer mortality in trials that included relatively younger, healthier, and predominantly White populations. The comorbidity profiles among patients undergoing lung cancer screening in practice settings are poorly understood.

Objective: To evaluate the comorbidity profiles of patients in the Personalized Lung Cancer Screening (PLuS) cohort as a clinical setting vs the National Lung Screening Trial (NLST) participants in a clinical trial setting.

Background: The management of incidental pulmonary nodules is guided by recommendations set forth by the Fleischner Society. Although most pulmonary nodules are benign, timely and evidence-based follow-up can reduce morbidity and mortality. There are known socioeconomic disparities for engagement with recommended cancer screenings; however, it is unclear whether disparities exist for follow-up of incidentally detected pulmonary lesions.

Lung nodules are frequently detected on low-dose computed tomography scans performed for lung cancer screening and incidentally detected on imaging performed for other reasons. There is wide variability in how lung nodules are managed by general practitioners and subspecialists, with high rates of guideline-discordant care. This may be due in part to the level of evidence underlying current practice guideline recommendations (primarily based on findings from uncontrolled studies of diagnostic accuracy).

After the Fontan procedure, patients require lifelong follow-up due to significant late morbidity and mortality. Thrombocytopenia is seen frequently post-Fontan, likely due to secondary hypersplenism from elevated Fontan pressure. We investigated platelet counts in patients with a Fontan circulation and assessed associations with catheterization data and clinical outcomes.

Purpose: Optimal timing of initiating invasive mechanical ventilation (IMV) in coronavirus disease 2019 (COVID-19)-related respiratory failure is unclear. We hypothesized that a strategy of IMV as opposed to continuing high flow oxygen or non-invasive mechanical ventilation each day after reaching a high FiO2 threshold would be associated with worse in-hospital mortality.

Methods: Using data from Kaiser Permanente Northern/Southern California's 36 medical centers, we identified patients with COVID-19-related acute respiratory failure who reached ≥80% FiO2 on high flow nasal cannula or non-invasive ventilation.
