Peer review during physician chart rounds is a major quality assurance and patient safety step in radiation oncology. However, the effectiveness of chart rounds in detecting problematic treatment plans is unknown. We performed a prospective blinded study of error detection at chart rounds to clarify the effectiveness of this quality assurance step. Methods and Materials: Radiation Oncology Incident Learning System publications were queried for problematic plans approved for treatment that would be detectable at chart rounds. A resident physician, physicist, and dosimetrist collaboratively generated 20 treatment plans with simulated errors identical in nature to those reported to the Radiation Oncology Incident Learning System. These were inserted randomly into weekly chart rounds over 9 weeks, with a median of 2 problematic plans presented per chart rounds (range, 1-4). Data were collected on detection, attendance, length, and number of cases presented at chart rounds. Data were analyzed using descriptive statistics and univariable logistic regression with odds ratios. Results: The median length of chart rounds over the study period was 60 minutes (range, 42-79); median number of cases presented per chart rounds was 45 (range, 38-50). The overall detection rate was 55% (11 of 20). Detection rates were higher for cases presented earlier in chart rounds: 75% versus 25% of problematic plans were detected within 30 minutes of start of chart rounds versus after 30 minutes (odds Sources of support: This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.

Social distancing is an effective strategy to limit contagion and mortality from the COVID-19 pandemic. However, these measures may also decrease perceived social connectedness and conversely increase social isolation, states which are associated with psychologic and physiologic morbidity. [1][2][3][4][5] Patients who are elderly or have disabilities are particularly encouraged to practice social distancing given their higher risk of severe COVID-19 infection, but they also have a higher baseline risk for reporting social isolation. 5,6 We hypothesized that the pandemic and social distancing measures have negatively affected perceptions of social connectedness among these high-risk patients.Methods | The Medicare Current Beneficiary Survey is an inperson, nationally representative survey of Medicare beneficiaries that is sponsored by the Centers for Medicare & Medicaid Services. We used the COVID-19 Summer 2020 Supplement data collected from June 10, 2020, to July 15, 2020. The institutional review board of Yale University approved the study and granted a waiver of informed consent because of the use of publicly available, deidentified data. The study cohort consisted of 9634 respondents who represented a weighted 50 851 437 community-dwelling beneficiaries who reported on changes in social connectivity during the pandemic (eMethods

Highlights Complete resection is a potentially curative treatment for pancreatic cancer. This report studies neoadjuvant chemotherapy with or without radiation. The addition of radiation was associated with improved complete resection rates. The addition of radiation was associated with improved pathologic down staging.
