Treatment charges for traumatic brain injury among older adults at a trauma center.
The objective of this study was to provide charge estimates of treatment for traumatic brain injury (TBI), including both hospital and physician charges, among adults 65 years and older treated at a trauma center. The study provided the first estimates of hospital and physician charges associated with hospitalization for TBI among older adults at a trauma center that will aid in resource allocation, triage decisions, and healthcare policy.

Associations of hospice disenrollment and hospitalization with continuous home care provision.
The researchers examined rates of hospice disenrollment and posthospice hospitalization among patients who are enrolled in hospices that provide continuous home care (CHC) (CHC hospices) compared with patients who are enrolled in hospices that do not offer CHC (non-CHC hospices). They concluded that CHC hospices had significantly lower rates of hospice disenrollment and posthospice hospitalization, suggesting CHC service available may enable higher quality of end-of-life care.

Trends in substance use admissions among older adults.
Researchers sought to analyze the trends in admissions for substance abuse treatment among older adults (aged 55 and older). Substantial changes in the demographic, substance use pattern, and treatment characteristics for the older adult admissions were noted. The proportion of admissions for following primary substances showed increase: cocaine/crack, marijuana/hashish, heroin, non-prescription methadone, and other opiates and synthetics.

Hospital variation in rates of new institutionalizations within 6 months of discharge.
The primary objective of this study was to examine the hospital-level variation in rates of new institutionalizations among Medicare beneficiaries. The overall observed rate of new institutionalizations was 3.6 percent (N = 173,998). Older age, white race, Medicaid eligibility, longer hospitalization, and having a skilled nursing facility stay over the 6 months before hospitalization were associated with higher adjusted odds. Observed rates ranged from 0.9 percent to 5.9 percent across states.

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.

Psychotropic medication use among Medicare beneficiaries following traumatic brain injury.
The researchers characterized psychotropic medication use before and after traumatic brain injury (TBI) hospitalization among older adults. They found that average monthly prevalence of psychotropic medication use among all patients hospitalized for TBI was 44.8 percent; antidepressants constituted 73 percent. Following TBI, psychotropic medication use increased slightly.

Reducing inpatient hospital and emergency room utilization among nursing home residents.
This study examined the association among nursing home residents between strength of relationship with a primary care provider (PCP) and inpatient hospital and emergency room (ER) utilization. Both measures of strength of patient-provider relationships were associated with fewer inpatient admissions and ER visits, except regularity of PCP visits and ambulatory care sensitive conditions (ACSC) ER visits.

Identifying specific combinations of multimorbidity that contribute to health care resource utilization: an analytic approach.
The objective was to identify specific combinations of chronic conditions, functional limitations, and geriatric syndromes associated with direct medical costs and inpatient utilization. The multimorbid population is heterogeneous and there is considerable variation in how specific combinations of morbidity influence resource use. Functional limitations were more important than many chronic diseases in explaining resource use.

Hospital contributions to variability in the use of ICUs among elderly Medicare recipients.
Hospitals vary widely in ICU admission rates across numerous medical diagnoses. In This retrospective cohort study examined the extent to which variability in ICU use is specific to individual diagnoses or is a function of the hospital, regardless of disease. The authors concluded that hospitals account for a significant proportion of variation independent of measured patient and hospital characteristics, suggesting the need for further work to evaluate the causes of variation at the hospital level and potential consequences of variation across hospitals.
