2011 National Healthcare Quality and Disparities Reports

The National Healthcare Quality Report (NHQR) is a comprehensive national overview of quality of health care in the United States. It is organized around four dimensions of quality of care: effectiveness, patient safety, timeliness, and patient centeredness.

^a. Complications of care include acute renal failure, pneumonia, pulmonary embolism, deep vein thrombosis, sepsis, shock, cardiac arrest, gastroentestinal hemorrhage, and acute ulcers.� Transfers from another hospital are excluded.� The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSI) software requires that the complication be reported as a secondary diagnosis (rather than the principal diagnosis), but unlike the AHRQ PSI software, the secondary diagnosis could be present on admission.� In addition, the surgery is not verifiable as occurring in the first 2 days of the inpatient stay.

^b. Rates are adjusted by age, comorbidities, major diagnostic category (MDC), diagnosis-related roup (DRG), and transfers into the hospital.� The AHRQ PSI software was modified to not use the present on admission (POA) indicators (or estimates of the likelihood of POA for secondary diagnosis).

Key: SE: standard error.
