Suitability of elderly adult hospital readmission rates for profiling readmissions in younger adult and pediatric populations.
Investigators sought to determine the correlation between hospital 30-day risk-standardized readmission rates in elderly adults and those in nonelderly adults and children. Data from U.S. hospitals in the 2013-2014 Nationwide Readmissions Database were used. The researchers found that hospital readmission rates in elderly adults may reflect broader hospital readmission performance in middle-aged and young adult populations, but they are not reflective of hospital performance in pediatric populations.

Using data from the Healthcare Cost and Utilization Project for state health policy research.
Investigators describe the opportunities and challenges of using HCUP data to conduct state health policy research and to provide empirical examples of what can go wrong when using the national HCUP data inappropriately. Analyzing cesarean delivery rates, discharges per capita, and discharges by the payer, they found that state-level estimates are volatile and often provide misleading policy conclusions. They conclude that the Nationwide Inpatient Sample should not be used for state-level research and specified that AHRQ provides resources to assist analysts with state-specific studies using State Inpatient Database files.

Challenges with quality of race and ethnicity data in observational databases.
This study assessed the quality of race and ethnicity information in observational health databases as well as electronic health records (EHRs) and to propose patient self-recording as a way to improve accuracy. Data from the Healthcare Cost and Utilization Project (HCUP) and Optum Labs, and from a single New York City healthcare system’s EHR was compared. Among 160 million patients in the HCUP database, no race or ethnicity data was recorded for 25% of the records. Among the 2.4 million patients in the New York City HER, race or ethnicity was unknown for 57%. However, when patients were allowed to directly record their race and ethnicity, percentages rose to 86%.

The HCUP SID imputation project: improving statistical inferences for health disparities research by imputing missing race data.
The purpose of this study was to identify the most appropriate imputation method for missing data in the HCUP State Inpatient Databases (SID) and assess the impact of different missing data methods on racial disparities research. The investigators found that conditional MI prediction was equivalent or superior to the best performing alternatives for all missing data structures and substantially outperformed each of the alternatives in various scenarios.

Association between the opening of retail clinics and low-acuity emergency department visits.
This study assessed whether the opening of retail clinics near emergency departments (ED) is associated with decreased ED utilization for low-acuity conditions. It concluded that with increased patient demand resulting from the expansion of health insurance coverage, retail clinics may emerge as an important care location, but to date, they have not been associated with a meaningful reduction in low-acuity ED visits.

Towards valid 'serious non-fatal injury' indicators for international comparisons based on probability of admission estimates.
The aim of this paper was to identify diagnoses with estimated high probability of inpatient admission (PrA) for selected developed countries. Its results confirmed that femoral fractures have high PrA across all countries studied. Strong evidence for high PrA also exists for fracture of base of skull with cerebral laceration and contusion; intracranial haemorrhage; open fracture of radius, ulna, tibia and fibula; pneumohaemothorax and injury to the liver and spleen.

Using Healthcare Cost and Utilization Project (HCUP) data for emergency medicine research.
This article mentions Kocher et al., elsewhere in this issue, who use the HCUP Nationwide Inpatient Sample to examine the association between the volume of ED encounters that result in admission and inpatient mortality. It further discusses HCUP strengths, weaknesses, and future.
