The DePICTORS Study: discrepancies in preliminary interpretation of CT scans between on-call residents and staff. | LitMetric

AI Article Synopsis

Article Abstract

At many academic hospitals, radiology residents provide preliminary interpretations of CT studies performed outside of regular working hours. We examined the rate of discrepancies between resident interpretations and final reports issued by staff. We prospectively obtained 1,756 preliminary reports and corresponding final reports for computed tomography (CT) scans performed on call between November 2006 and March 2007. The overall rate of clinically significant discrepancies (those that would potentially alter the patient's clinical course prior to issue of the final report) was 2.0%. Major discrepancy rates for abdominal/pelvic, chest, cervical spine and head CT were 4.1%, 2.5%, 1.0% and 0.7%, respectively. Senior residents had fewer major discrepancies compared to their junior colleagues. Time of interpretation was also evaluated, but a statistically significant relationship was not observed. In summary, this study demonstrates a low discrepancy rate between residents and staff radiologists and identifies areas where after-hours service may be further improved.

Background: The low-pressure, hypoxic environment characteristic of high-altitude regions significantly affects the cardiovascular and autonomic nervous system functions of individuals, consequently impairing their sleep quality. Heart rate variability, a non-invasive indicator of autonomic nervous system activity and balance within the cardiovascular system, has not been thoroughly investigated in terms of its patterns during acclimatization and de-acclimatization phases for individuals traveling to and residing in high-altitude areas and its relationship with sleep stability.

Methods: Data was collected from 22 medical staff members who traveled from Chengdu to Yecheng, with measurements taken before leaving Chengdu, 1 week in Yecheng, 3 months in Yecheng, and 1 week after returning to Chengdu.

Access to Pediatric Bed Capacity According to Social Determinants of Health: All Beds Are Not Created Equal.

J Pediatr

December 2024

Department of Pediatrics, Boston University Chobanian & Avedisian School of Medicine, Boston, MA, USA; Department of Cardiology, Boston Children's Hospital, Boston, MA, USA; Children's Hospital at Westmead Clinical School, Faculty of Medicine and Health, The University of Sydney, Sydney, NSW, Australia; Sandra L. Fenwick Institute for Pediatric Health Equity and Inclusion, Boston Children's Hospital, Boston, MA, USA. Electronic address:

Objective: To study pediatric inpatient hospital capacity and resources, characterizing differences according to social determinants of health (SDoH) using market share techniques.

Study Design: This cross-sectional study uses non-elective inpatient discharges (≥1 month to ≤19 years) from Healthcare Cost and Utilization Project and American Hospital Association surveys to derive hospital capacity and resources/capability. We include US hospitals with ≥1 pediatric bed and ≥1 pediatric discharge and calculate per bed capital, expenditure, and staffing, transfer rates, payer-mix, and adjusted central line-associated blood stream infection (CLABSI) rate.

Background: The importance of social health is increasingly recognized in dementia research. For most people living with dementia, their social environment changes as the disease progresses, especially when they move into a long-term care facility. However, maintaining social interactions in the new living environment contributes significantly to health and quality of life.

Background: During the COVID-19 pandemic, governments across the world implemented processes and policies to limit the spread of COVID-19, especially in long-term care (LTC) homes. This led to changes in technology use for persons living in LTC homes, their families and friends, as well as the paid workforce dedicated to caring for them.

Objective: The study describes the role of technology and its impact on the experiences of LTC staff working in northern and rural areas in Western Canada during COVID-19.

Objectives In Japan, efforts to provide "end-of-life care" in nursing homes are increasing and its introduction through long-term care insurance in 2006 is a major step forward. However, previous studies have shown that relocating older adults to their end-of-life care affects their burden. This study examined individuals' end-of-life care use under long-term care insurance in older care facilities and investigated the relocation frequency among terminally ill older residents of nursing facilities using receipt data.
