Background: A substantial percentage of the US population is not up to date on guideline-recommended cancer screenings. Identifying interventions that effectively improve screening rates would enhance the delivery of such screening. Interventions involving health IT (HIT) show promise, but much remains unknown about how HIT is optimized to support cancer screening in primary care.

Social determinants of health and unmet social needs are directly related to cancer outcomes, from diagnosis to survivorship. If identified, unmet social needs can be addressed in oncology care by changing care plans in collaboration with patients' preferences and accounting for clinical practice guidelines (eg, reducing the frequency of appointments, switching treatment modalities) and connecting patients to resources within healthcare organizations (eg, social work support, patient navigation) and with community organizations (eg, food banks, housing assistance programs). Screening for social needs is the first step to identifying those who need additional support and is increasingly recognized as a necessary component of high-quality cancer care delivery.

Importance: Early in the COVID-19 pandemic, states implemented temporary changes allowing physicians without a license in their state to provide care to their residents. There is an ongoing debate at both the federal and state levels on whether to change licensure rules permanently to facilitate out-of-state telemedicine use.

Objective: To describe out-of-state telemedicine use during the pandemic.

Health-care-related transportation insecurity is common in the United States. Patients with cancer are especially vulnerable because cancer care is episodic in nature, occurs over a prolonged period, is marked by frequent clinical encounters, requires intense treatments, and results in substantial financial hardship. As a result of transportation insecurity, patients with cancer may forego, miss, delay, alter, and/or prematurely terminate necessary care.

To understand how differences in primary care appointment completion rates between Black and non-Black patients changed in 2020 within the context of the COVID-19 pandemic and when telemedicine utilization peaked. We conducted a retrospective cohort study using the electronic health record from January 1 to December 31, 2020, among all adults scheduled for a primary care appointment within a large academic medical center. We used mixed-effects logistic regression to estimate adjusted appointment completion rates for Black patients compared with those for non-Black patients in 2020 as compared with those in 2019 within four time periods: (1) prepandemic (January 1, 2020, to March 12, 2020), (2) shutdown (March 13, 2020, to June 3, 2020), (3) reopening (June 4, 2020, to September 30, 2020), and (4) second wave (October 1, 2020, to December 31, 2020).

Objective: We describe the design, implementation, and validation of an online, publicly available tool to algorithmically triage patients experiencing severe acute respiratory syndrome coronavirus (SARS-CoV-2)-like symptoms.

Methods: We conducted a chart review of patients who completed the triage tool and subsequently contacted our institution's phone triage hotline to assess tool- and clinician-assigned triage codes, patient demographics, SARS-CoV-2 (COVID-19) test data, and health care utilization in the 30 days post-encounter. We calculated the percentage of concordance between tool- and clinician-assigned triage categories, down-triage (clinician assigning a less severe category than the triage tool), and up-triage (clinician assigning a more severe category than the triage tool) instances.
