Falls in older adults requiring emergency services: mortality, use of healthcare resources, and prognostication to one year.
The purpose of this study was to assess the prognoses, healthcare use, transitions to skilled nursing or hospice, and mortality of older, community-living adults after a fall. The researchers conducted a secondary analysis of all adults in 7 Northwest U.S. counties greater than or equal to 65 years of age who had been transported to one of 51 hospitals after a fall. The study analyzed Medicare claims, state trauma registry data, state inpatient data, and death records for outcomes which included healthcare use, new claims for skilled nursing and hospice for one year, and mortality. The researchers found that in 3,159 older adults there were 147 deaths within 30 days and 665 deaths within one year, and the following predictors of mortality: respiratory diagnosis, serious brain injury, having a baseline disability, or a score of greater than or equal to 2 on the Charlson Comorbidity Index. The study concluded that in the year after experiencing a fall, community-living older adults who require ambulance transport to the hospital have increases in institutionalized living, the utilization of health care, and mortality.

Approaches to address premature death of patients when assessing patterns of use of health care services after an index event.
In this study, the investigators compared different approaches for cohort definition (restriction by survival time vs. comorbidity score) and analysis method [Kaplan-Meier (KM) vs. competing risk] when assessing patterns of guideline adoption in elderly patients. They found that the KM method consistently overestimated the competing risk method. They suggest that competing risk approaches avoid unrealistic mortality assumptions and lead to interpretations of estimates that are more meaningful.

Frequency of care and mortality following an incident diagnosis of peripheral artery disease in the inpatient or outpatient setting: the ARIC (Atherosclerosis Risk in Communities) study.
Researchers analyzed frequency of care and mortality date for patients with an initial peripheral artery disease (PAD) diagnosis in the outpatient or inpatient setting. Data was analyzed from the ARIC (Atherosclerosis Risk in Communities) study cohort linked with Centers for Medicare and Medicaid Services fee-for-services claims data for 2002-2012. Patients diagnosed in the outpatient setting had higher follow-up rates with lower hospitalizations and mortality than those diagnosed in the inpatient setting.

Long-term reduction of health care costs and utilization after epilepsy surgery.
This study assessed long-term direct medical costs, health care utilization, and mortality following resective surgery in persons with uncontrolled epilepsy. It found that the mean direct medical cost difference between the surgical group and control group was $6,806 after risk-set matching. The incidence rate ratio of inpatient, emergency room, and outpatient utilization was lower among the surgical group in both unadjusted and adjusted analyses.

Resource use in the last year of life among patients who died with versus of prostate cancer.
The researchers conducted a retrospective analysis of Surveillance, Epidemiology, and End Results-Medicare data of men with prostate cancer. Patients who died of prostate cancer rather than from other causes had more hospice and outpatient use, less inpatient and ICU use, and lower overall costs. Efforts to shift care toward outpatient settings might provide more efficient and judicious care for patients during the end of life.

Health-care utilization by prognosis profile in a managed care setting: using the Surveillance, Epidemiology and End Results Cancer Survival Calculator SEER*CSC.
The authors described health service utilization patterns of subgroups of prostate cancer and colorectal cancer (CRC) patients with different relative probabilities of dying of their cancer or other conditions. They found that although a new diagnosis of cancer increased utilization of cancer-related services for an extended time period, the timing of cancer diagnosis did not appear to affect other types of utilization.

Use of intensive care services and associated hospital mortality after Massachusetts healthcare reform.
This study examined the impact of increased insurance coverage on intensive care unit (ICU) usage and mortality in Massachusetts where health insurance reform had expanded coverage. It found that reform was not associated with either significant changes in ICU use or changed hospital mortality for ICU patients.
