Clarity on disparity: who, what, when, where, why, and how.
This purpose of this article was to explain a comprehensive framework of health disparities descriptors that can offer a systematic approach to advance the understanding of causes of health disparities and facilitate action steps to ensure health equity.

Association of health insurance coverage disruptions with mortality risk among US working-age adults.
This cohort study assessed associations of a prior coverage disruption with mortality risk among large, nationally representative cohorts of working-age adults aged 18 to 64 with public or private health insurance coverage. Most research had previously been conducted among Medicaid enrollees, and little is known about insurance disruption among privately insured adults. The study used data from the 2000 to 2018 National Health Interview Survey (NIHS), specifically from the NHIS Linked Mortality files which contain data from the National Death Index. All data was deidentified and publicly available. The authors found that disruptions were associated with a higher mortality risk in either publicly or privately insured adults.

Mortality and access to kidney transplantation in patients with sickle cell disease-associated kidney failure.
Patients with sickle cell disease-associated kidney failure have high mortality, which might be lowered by kidney transplantation. However, because they show higher post-transplant mortality compared with patients with other kidney failure etiologies, kidney transplantation remains controversial in this population. In this study, the investigators aimed to quantify the decrease in mortality associated with transplantation in this population and determine the chance of receiving transplantation with sickle cell disease as the cause of kidney failure as compared with other etiologies of kidney failure.

Association between operating room access and mortality for life-threatening general surgery emergencies.
Few diseases truly require emergency surgery today. In this study, the authors investigated the relationship between access to operating room (OR) and outcomes for patients with life-threatening emergency general surgery (LT-EGS) diseases at US hospitals. The investigators concluded that round-the-clock availability of personnel, specifically emergency general surgeons and recovery room nurses, is associated with decreased mortality.

Factors mediating demographic determinants of injury mortality.
The authors investigated the role of injury characteristics and access to trauma care as mediators of the relationships between race, ethnicity, sex, and injury mortality. They found that distance, injury characteristics, and insurance mediate the effects of demographic characteristics on injury mortality and appear to contribute to disparities in injury mortality.

Prolonged wait time is associated with increased mortality for Chilean waiting list patients with non-prioritized conditions.
This study looked at mortality rates of Chilean patients on waiting lists for non-prioritized medical treatment within their universal healthcare system. There was a statistically significant association between waiting time and mortality for patients observed in the study. The study used data from 987,497 patients at 77 medical centers from 2008 to 2015. Three geographically distant regions were studied and there was a large region-to-region variation in mortality rates.

Associations of distance to trauma care, community income, and neighborhood median age with rates of injury mortality.
The purpose of this study was to examine the association of injury scene characteristics with injury mortality. The study concluded that injury scene characteristics are associated with injury mortality. The authors found that odds of death are highest for patients injured in communities with higher median age or lower per capita income and at locations farthest from level 1 or 2 trauma centers.

Medicaid's lasting impressions: population health and insurance at birth.
This article examines lasting mortality improvements associated with availability of Medicaid at time and place of birth. Being born after Medicaid was associated with between 2.03 and 3.64 fewer deaths per 100,000 person-years in childhood and between 1.35 and 3.86 fewer deaths per 100,000 person-years in the thirties. The association between Medicaid at birth and mortality was the strongest in the oldest age group (36-40) in this study.

It's all about location, location, location: A new perspective on trauma transport.
The objective of this study was to determine the effect of aeromedical transport on trauma mortality when accounting for geographic factors. It concluded that helicopter transport does not impart a survival benefit for trauma patients when geographic considerations are taken into account.

How does geographic access affect in-hospital mortality for veterans with acute ischemic stroke?
This study examined the relationship between estimated travel time to admitting hospital and mortality for veterans with acute ischemic stroke. It found that even after adjusting for the confounding effects of patient, treatment, and facility characteristics, travel time from home to admitting VAMC was significantly associated with inhospital mortality.
