Data Catalog

The largest all-payer ambulatory surgery database in the United States, the Nationwide Ambulatory Surgery Sample (NASS) produces national estimates of major ambulatory surgery encounters in hospital-owned facilities. The NASS contains clinical and resource-use information that is included in a typical hospital-owned facility record, including patient characteristics, clinical diagnostic and surgical procedure codes, disposition of patients, total charges, expected source of payment, and facility characteristics.

The Pediatric Participant Use Data File (PUF) is a Health Insurance Portability and Accountability Act (HIPAA)-compliant data file containing cases submitted to the American College of Surgeons National Surgical Quality Improvement Program Pediatric® (ACS NSQIP Pediatric®). The PUF contains patient-level, aggregate data and does not identify hospitals, health care providers, or patients. The ACS NSQIP Pediatric collects data on approximately 120 variables, including preoperative risk factors, intraoperative variables, and 30-day postoperative mortality and morbidity outcomes for patients undergoing major surgical procedures in both the inpatient and outpatient setting. The intended purpose of this file is to provide researchers at participating sites with a data resource they can use to investigate and advance the quality of care delivered to the surgical patient through the analysis of cases captured by ACS NSQIP Pediatric. Additional procedure-specific PUFs are available for appendectomy, spinal fusion, and cerebrospinal fluid shunt.

The Mass Mobilization (MM) data are an effort to understand citizen movements against governments, what citizens want when they demonstrate against governments, and how governments respond to citizens. The project codes protests against governments - the data cover 162 countries between 1990 and March 2017. For each protest event, the project records protester demands, government responses, protest location, and protester identities. The Principle Investigators for the Mass Mobilization project are David H. Clark (Binghamton University) and Patrick M. Regan (University of Notre Dame). The Mass Mobilization project is sponsored by the Political Instability Task Force (PITF). The PITF is funded by the Central Intelligence Agency.
