Ecological risk and protective factors for food insufficiency in Los Angeles County during the COVID-19 pandemic.

Objective: The COVID-19 pandemic increased food insufficiency: a severe form of food insecurity. Drawing on an ecological framework, we aimed to understand factors that contributed to changes in food insufficiency from April to December 2020, in a large urban population hard hit by the pandemic.

Design: We conducted internet surveys every 2 weeks in April-December 2020, including a subset of items from the Food Insecurity Experience Scale.

Using business intelligence and data visualization to understand the characteristics of failed appointments in dental school clinics.

Purpose/objectives: Broken appointments are an important cause of waste in health care. Patients who fail to attend incur costs to providers, deny trainees learning opportunities, and impact their own health as well as that of other patients who are waiting for care.

Methods: A total of 410,000 appointment records over 3 years were extracted from our electronic health record.
