Empirical investigation of techniques for handling missing cost-to-charge ratio (CCR) in nationwide inpatient sample (NIS)

Nationwide incidence, cost, and epidemiologic trends in facial rhytidectomy: an examination of inpatient facelifts using the Nationwide Inpatient Sample (NIS) database.

Facelifts are consistently one of the most common aesthetic operations performed by plastic surgeons in the United States (US). In 2013, 133,320 procedures were recorded, a rise of 6% compared with the previous year, making facelift the fifth most commonly performed cosmetic procedure. Further, rhytidectomy has been found to be safe in a wider, older range of patients, making it more popular wi...

Overview of Disease Severity Measures Disseminated with the Nationwide Inpatient Sample (NIS) and Kids’ Inpatient Database (KID)

Adding severity adjustment measures to the HCUP Nationwide Inpatient Sample (NIS) and Kids’ Inpatient Database (KID) will significantly enhance the datasets for research purposes. An evaluation of alternative severity adjustment systems was conducted, focusing on those systems that require only hospital administrative data. The evaluation was conducted for AHRQ by an outside researcher who is n...

A comparison of a multistate inpatient EHR database to the HCUP Nationwide Inpatient Sample

BACKGROUND The growing availability of electronic health records (EHRs) in the US could provide researchers with a more detailed and clinically relevant alternative to using claims-based data. METHODS In this study we compared a very large EHR database (Health Facts©) to a well-established population estimate (Nationwide Inpatient Sample). Weighted comparisons were made using t-value and rela...

Regional variation in total cost per radical prostatectomy in the healthcare cost and utilization project nationwide inpatient sample database.

PURPOSE Surgical treatment for prostate cancer represents a large national health care expenditure. We determined whether state level variation in the cost of radical prostatectomy exists and whether we could explain this variation by adjusting for covariates associated with cost. MATERIALS AND METHODS Using the 2004 Healthcare Cost and Utilization Project National Inpatient Sample of 7,978,0...
