The association of missed nursing care with very low birthweight infant outcomes.
This study examined the association of missed nursing care and health outcomes of very low birthweight (VLBW) infants in neonatal intensive care units (NICUs). The authors used 2016 hospital administrative discharge abstracts for VLBW newborns (n = 7,595) and NICU registered nurse survey responses (n = 6,963) from the National Database of Nursing Quality Indicators. Mortality, morbidity, and length of stay (LOS) was examined in 190 sample hospitals from 19 states in all regions. There was a significant association between higher odds of bloodstream infection and longer LOS, but not mortality or severe intraventricular hemorrhage and missed nursing care.

Utilization of minimally invasive surgery and its association with chemotherapy for locally advanced gastric cancer.
This study compared outcomes of patients with T3 or greater and/or N+ gastric carcinoma who had minimally invasive surgery (MIS) or traditional open surgery. Patients who received MIS had a greater likelihood of receiving postoperative chemotherapy. Patients from the National Cancer Database (21,872) from 2010 to 2015 were identified. The majority (72.2%) received open surgery although MIS rates went up during that time period. Predictors of MIS were Asian race, any insurance coverage and treatment at high-volume centers. Survival rates were higher for MIS patients although that could be explained by their increased likelihood of receiving adjuvant chemotherapy.

Utilization trends, outcomes, and cost in minimally invasive lobectomy.
The objective of this study was to compare outcomes and hospitalization costs among patients undergoing open, video-assisted thoracoscopic surgery (VATS) and RATS lobectomy. The investigators concluded that minimally invasive approaches were associated to improved clinical outcomes compared with open lobectomy. However, only robotic-assisted lobectomy has had rapid growth in utilization. Despite additional cost, RATS lobectomy appeared to provide a viable minimally invasive alternative for general thoracic procedures.

Denver ED Trauma Organ Failure Score predicts healthcare resource utilization in adult trauma patients.
This study examined the success of the Denver Emergency Department (ED) Trauma Organ Failure (TOF) Score and the need for specialized healthcare resources for trauma patients. Outcomes measured included intensive care unit (ICU) length of stay (LOS), hospital LOS, procedures and costs. They included 3000 patients with 71% of them male, a median age of 42, and median injury severity score of 9 (IQR 5-16). Of that total, 46% were admitted to the ICU and 4% died. The tool was found to successfully predict healthcare resource utilization and can be used to identify patients early after injury that will require specialized trauma care.

A national analysis of pediatric trauma care utilization and outcomes in the United States.
The goal of this study was to provide the first national description of the proportion of injured children treated at pediatric trauma centers, and to clarify the presumed benefit of pediatric trauma center verification by comparing injury mortality across hospital types. The study used data from the 2006 Healthcare Cost and Utilization Project Kids Inpatient Database combined with national trauma center inventories. The results of the study may provide evidence that treatment of injured children at verified pediatric trauma centers may improve outcomes.

The impact of an adolescent depressive disorders clinical pathway on healthcare utilization.
The purpose of this study was to examine the association between level of adherence to an adolescent depressive disorders inpatient clinical pathway with psychiatric patients’ length of stay (LOS), cost, and readmissions. Patients in the high-adherence category were found to have significantly longer LOS and higher costs when compared to those in the low-adherence category. The authors conclude that understanding which of the care processes within the pathway are most cost-effective for improving patient-centered outcomes requires further investigation.

Effects of a 1-time nurse-led telephone call after pediatric discharge: the H2O II randomized clinical trial.
The purpose of this study was to determine whether a single nurse-led telephone call after pediatric discharge decreased the 30-day reutilization rate for urgent care services and enhanced overall transition success. The investigators concluded that although postdischarge nurse contact did not decrease the reutilization rate of postdischarge urgent health care services, the method showed promise to bolster postdischarge education.

Associations of race and ethnicity with patient-reported outcomes and health care utilization among older adults initiating a new episode of care for back pain.
The purpose of this study was to characterize associations of self-reported race/ethnicity with back pain (BP) patient-reported outcomes and health care utilization among older adults with a new episode of care for BP. The investigators found that Blacks and Hispanics had slightly less improvement in BP-related functional limitations over time, and less spine-related health care utilization, as compared to whites and non-Hispanics, respectively. The authors suggested that residual confounding may explain some of the association between race/ethnicity and health outcomes.

Sex and race differences in the utilization and outcomes of coronary artery bypass grafting among Medicare beneficiaries, 1999-2014.
The authors sought to evaluate how the use of coronary artery bypass grafting (CABG) and its outcomes have evolved in different sex and racial subgroups. Using Medicare data, they found that women and black patients had persistently higher CABG mortality than men and white patients, respectively, despite greater declines over the time period. The authors conclude that these findings indicate progress, but further progress is needed.

Do Medicaid benefit expansions have teeth? The effect of Medicaid adult dental coverage on the use of dental services and oral health.
This article examines the effect of Medicaid adult dental coverage on use of dental care and dental health outcomes using state-level variation in dental coverage during 2000-2012. Its findings imply that dental coverage is associated with an increase in the likelihood of a recent dental visit, with the size of the effect increasing with Medicaid payment rates to dentists, and a reduction in the likelihood of untreated dental caries.

The effect of health insurance coverage on medical care utilization and health outcomes: evidence from Medicaid adult vision benefits.
The reserarchers examined the effect of vision insurance on eye care utilization and vision health outcomes by taking advantage of quasi-experimental variation in Medicaid coverage of adult vision care. They found that Medicaid beneficiaries with vision coverage are 4.4 percentage points more likely to have seen an eye doctor in the past year,and 5.3 percentage points less likely to report needing but not purchasing eyeglasses or contacts due to cost.

When do patient-reported outcome measures inform readmission risk?
The study sought was to characterize changes in patient-reported outcome measures from hospital discharge to assess when they best inform risk of utilization as defined by readmissions or emergency department use. It concluded that routine measurement of patient-reported outcomes can help identify patients at higher risk for utilizations. For example, in-hospital assessments revealing high symptom burden and poor health status predicted 14-day reutilization.
