Hospital Discharge & Outpatient/ASC Surgery Data ·Reports and Order Form

Public Use Data Files (PUDF) – Inpatient, Hospital-based Outpatient Surgery and Free-standing Ambulatory Surgery Center (ASC) Discharge Data

Under the provisions of the Health Care Information Statutes (63 O.S. (Supp. 1994) § 1-115 et seq.), the Division prepares and makes available a public use file for the three datasets; Inpatient, Hospital-based Outpatient Surgery and ASC Discharge Data. The Public files contain patient level data but considerable efforts are taken to ensure that individual patients are not identified in the PUDF. Public files are designed to provide public health personnel, purchasers, payers, providers, consumers and researchers useful information to make informed decisions. Please refer to the following data dictionaries for a list of the fields and its descriptions. Instructions for ordering the public file are available on the data Discharge Order Form (342 KB pdf).

Health Care Cost and Utilization Project (HCUP) 

Oklahoma participates in the Agency for Healthcare Quality and Research (AHRQ) sponsored Healthcare Cost and Utilization Project (HCUP) since the 2005 data year. HCUP data is a powerful resource for national and state health care statistics. 

HCUPnet is a free, on-line query system based on data from the Healthcare Cost and Utilization Project (HCUP).

Quality Indicators 

Using Hospital Inpatient Discharge Data, the Agency for Healthcare Research and Quality (AHRQ) has developed a set of Quality Indicators (QIs) that measure a range of health care quality issues. The QIs are arranged in four modules:

  • Inpatient Quality Indicators (IQIs) reflect quality of care inside hospitals including inpatient mortality for medical conditions and surgical procedures. (46.2KB pdf)
  • Patient Safety Indicators (PSIs) reflect the quality of care inside hospitals, focusing on avoidable complications and iatrogenic events. (81.9KB pdf)
  • Prevention Quality Indicators (PQIs) identify admissions that evidence suggests could have been avoided, at least partially, through high-quality outpatient care.(43.3KB pdf)
  • Pediatric Quality Indicators reflect quality of care inside hospitals and identify potentially avoidable hospitalizations among children.(44.7KB pdf)
