Development of a healthcare system COVID Hotspotting Score in California: an observational study with prospective validation.

Objective: To examine the value of health systems data as indicators of emerging COVID-19 activity.

Design: Observational study of health system indicators for the COVID Hotspotting Score (CHOTS) with prospective validation.

Setting And Participants: An integrated healthcare delivery system in Northern California including 21 hospitals and 4.

A successful program preventing nonventilator hospital-acquired pneumonia in a large hospital system.

Objective: To develop and evaluate a program to presvent hospital-acquired pneumonia (HAP).

Design: Prospective, observational, surveillance program to identify HAP before and after 7 interventions. An order set automatically triggered in programmatically identified high-risk patients.

Enhanced Recovery After Surgery to Change Process Measures and Reduce Opioid Use After Cesarean Delivery: A Quality Improvement Initiative.

Objective: To evaluate implementation of an enhanced recovery after surgery (ERAS) program for patients undergoing elective cesarean delivery by comparing opioid exposure, multimodal analgesia use, and other process and outcome measures before and after implementation.

Methods: An ERAS program was implemented among patients undergoing elective cesarean delivery in a large integrated health care delivery system. We conducted a pre-post study of ERAS implementation to compare changes in process and outcome measures during the 12 months before and 12 months after implementation.

Composition or Context: Using Transportability to Understand Drivers of Site Differences in a Large-scale Housing Experiment.

Background: The Moving To Opportunity (MTO) experiment manipulated neighborhood context by randomly assigning housing vouchers to volunteers living in public housing to use to move to lower poverty neighborhoods in five US cities. This random assignment overcomes confounding limitations that challenge other neighborhood studies. However, differences in MTO's effects across the five cities have been largely ignored.
