The shifting landscape in utilization of inpatient, observation, and emergency department services across payers.
Using data from four states from AHRQ’s Healthcare Cost and Utilization Project, this study compared the payer-specific population-based rates of adults using inpatient, observation, and emergency department (ED) services for 10 common medical conditions in 2009 and in 2013. Inpatient admissions declined, and care shifted toward treat-and-release observation stays and ED visits. The percentage of hospitalizations that began with an observation stay increased.

Identification of emergency department visits in Medicare administrative claims: approaches and implications.
The researchers sought to construct an operational definition for ED visitation using a comprehensive Medicare data set and to compare this definition to existing operational definitions used by researchers and policymakers. They concluded that current operational definitions of ED visitation using administrative claims produce different estimates of ED visitation based on the underlying assumptions applied to billing data and data set availability.

Colorado cannabis legalization and its effect on emergency care.
The authors noted that increased marijuana use after legalization has been accompanied by increases in emergency department visits and hospitalizations due to marijuana intoxication. They recommended that providers in states with impending legalization measures should become familiar with the symptoms and management of acute marijuana intoxication, as well as understand the effects on chronic diseases frequently observed in the emergency department. Further, they suggested that residency program directors should make an effort to integrate this topic into their residency curricula.

Observation units as substitutes for hospitalization or home discharge.
The purpose of this study is to determine the effect of the availability of observation units on hospitalizations and discharges to home for emergency department (ED) patients. The authors concluded that half of ED visits for chest pain that resulted in an observation unit admission were made by patients who may have been discharged home had the observation unit not been available.

Direct admission to the hospital: an alternative approach to hospitalization.
The authors discussed the role of hospital medicine in the changing epidemiology of hospital admissions, the potential risks and benefits of direct admission to the hospital, and the need for research to evaluate the safety and effectiveness of this admission approach. They proposed that transitions of care research and quality improvement be expanded to address transitions into the hospital.

Ambulatory care sensitive hospitalizations through the emergency department by payer: comparing 2003 and 2009.
This study compared rates of ED ambulatory care sensitive hospitalizations (ACSHs) for 2003 and 2009 among patients 18 to 64 years of age with private insurance, Medicaid, or no insurance.It found that an increase in the uninsured population was associated with an increase in the rate of ED ACSH for uninsured patients.

Emergency department crowding and outcomes after emergency department discharge.
The researchers assess whether a panel of emergency department (ED) crowding measures, including 2 reported by the Centers for Medicare & Medicaid Services (CMS), is associated with inpatient admission and death within 7 days of ED discharge. Their findings suggest that ED length of stay is a proxy for unmeasured differences in case mix and challenge the validity of the CMS metric as a safety measure for discharged patients.

Appropriateness of disposition following telemedicine consultations in rural emergency departments.
The researchers compared the overall and stratified observed-to-expected hospital admission ratios between telemedicine and telephone cohorts of acutely ill and injured children. They found that there were no statistically significant differences between the observed-to-expected admission ratios using Pediatric Risk of Admission II and Revised Pediatric Emergency Assessment Tool.

A patient navigation intervention for drug-involved former prison inmates.
The researchers designed a randomized controlled trial of patient navigation to reduce barriers to health care and hospitalizations for former prison inmates. They found recruitment of former inmates highly feasible, but found that follow-up was limited by rearrests. They concluded that their results suggest a significantly lower rate of hospitalizations among navigation participants, although the rate of emergency department/urgent care visits was not improved.

Variation in emergency department admission rates across the United States.
The authors investigated factors related to variation in hospital-level emergency department (ED) admission rates. Using HCUP data, they found that higher proportions of Medicare and uninsured patients, more inpatient beds, lower ED volumes, for-profit ownership, trauma center status, and higher hospital occupancy rates were associated with higher ED admission rates.
