Geriatric syndrome risk factors among hospitalized postacute Medicare patients.
The purpose of this study was to assess the association of geriatric syndrome risk factors with postacute utilization among hospitalized Medicare patients (both Medicare Advantage [MA] and fee-for-service [FFS] cohorts) and to examine patterns of postacute care for MA and FFS cohorts with high geriatric syndrome risk. The investigators found that geriatric syndrome risk factors not only play a role in postacute care and inpatient utilization in MA and FFS cohorts but also explain different utilizations between MA and FFS cohorts.

Nonspecific chest pain and hospital revisits within 7 days of care: variation across emergency department, observation and inpatient visits.
The purpose of this study was to compare the rate at which patients with nonspecific chest pain return to the hospital within 7 days after index observation visits versus after index emergency department and inpatient visits. Findings showed that up to 1 in 10 patients discharged with nonspecific chest pain returned to the hospital within 1week. Compared with emergency department and inpatient care, observation visits were associated with lower revisit rates. Recommendations include further research to refine clinical standards of care for nonspecific chest pain as well as to investigate the healthcare delivery and patient factors that influence 7-day revisit rates.

Antenatal corticosteroid administration in late-preterm gestations: a cost-effectiveness analysis.
The purpose of this study was to evaluate whether administration of antenatal late-preterm betamethasone was cost-effective in the immediate neonatal period. Cost-effectiveness analysis of late-preterm betamethasone administration with a time horizon of 7.5 days was conducted using a health-system perspective The investigators concluded that administration of betamethasone in the late-preterm period was likely not cost-effective in the short-term.

The potential health care costs and resource use associated with COVID-19 in the United States.
The authors developed a Monte Carlo simulation model representing the U.S. Population and what can happen to every person who gets infected with COVID-19. The goal was to estimate resource use and direct medical costs per infection at the national level at different infection rates. They found that a single symptomatic COVID-19 infection would cost a median of $3,045 in direct medical costs. If 80% of the population got infected it would cost $654.0 billion in direct costs during the course of the pandemic. If 20% were to become infected, direct costs are estimated at $163.4 billion.

Utilization and treatment patterns of cytoreduction surgery and intraperitoneal chemotherapy in the United States.
This paper discusses utilization and treatment patterns of cytoreduction surgery and intraperitoneal chemotherapy (CRS/IPC) treatment for patients with peritoneal metastases (PM) in the United States. This treatment is becoming more popular in the US. The authors used the National Inpatient Sample to identify patients from 2006 to 2015 who underwent CRS/IPC. The number of CRS/IPC treatments increased from 189 to 1540. The most common indication was for appendiceal cancer, followed by ovarian and colorectal cancers. The procedure was performed the most in large teaching hospitals. The authors recommend the creation of a national registry dedicated to cases of IPC to help evaluate further use and outcomes.

The purpose of this retrospective cohort study was to assess whether trends in elective and urgent/emergent colectomy changed after July 2006. The authors suggest that given the risks associated with elective colectomy, their findings demonstrate the need for a more evidence-based decision-making process, incorporating both patient preferences and patient-reported outcomes, for those considering elective colectomy for uncomplicated and some cases of complicated diverticulitis.

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.

Changes in hospital service demand, cost, and patient illness severity following health reform.
This study examined the effects of expanded Medicaid coverage and the health insurance exchange on the number of hospital inpatient and emergency department (ED) utilization rates, cost, and patient illness severity. There was a significant drop in uninsured inpatient discharges and ED visits in states where Medicaid was expanded. For all by young females, uninsured inpatient discharge rates fell by 39% or greater. In nonexpansion states, the rates remained unchanged or increased slightly. Changes in all-payer and private insurance rates were not as dramatic, as was inpatient costs per discharge and all-payer inpatient costs.

Does cannabis legalisation change healthcare utilisation? A population-based study using the healthcare cost and utilisation project in Colorado, USA.
Researchers studied whether the legalization of cannabis in Colorado has affected healthcare utilization compared to two states where it is still illegal (New York and Oklahoma). ICD-9 was used to determine changes in healthcare utilization relative to various medical diagnoses. According to the National Academy of Science (NAS), legal cannabis use creates an increase in cannabis abuse hospitalizations and also linked to motor vehicle accidents, alcohol abuse, and overdose injury and that was true in CO. There was not a change in hospital stays and costs in CO compared to NY and OK.

Trends in lumbar fusion procedure rates and associated hospital costs for degenerative spinal diseases in the United States, 2004 to 2015.
This study analyzed trends in lumbar fusion procedure rates for degenerative spinal diseases in the US from 2004 to 2015 as well as associated hospital costs. Spinal fusion is considered an appropriate procedure for spinal deformity and instability, but has limited evidence of effectiveness for primary disc herniation and spinal stenosis without instability. The analysis showed that aggregate hospital costs increased 177% during the analysis period with disc degeneration, herniation and stenosis accounted for 42.3% of the elective surgery. The largest increases in the elective surgery were for spondylolisthesis and scoliosis and has slightly decreased for those procedures with less evidence of effectiveness.

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.

Risk of subsequent joint arthroplasty in contralateral or different joint after index shoulder, hip, or knee arthroplasty: association with index joint, demographics, and patient-specific factors.
The purpose of this study using HCUP data was to determine how demographic and other patient-specific factors are associated with the risk of subsequent joint replacement in the contralateral or a different joint following an index joint replacement for osteoarthritis. Results showed a relatively high risk of subsequent replacement of the contralateral joint and a relatively low risk of subsequent replacement of a different joint within 5 to 8 years after an index total hip arthroplasty, total knee arthroplasty, or total shoulder arthroplasty. Obesity was associated with a higher risk of subsequent replacement of the contralateral joint or a different joint.

Acute exacerbation of chronic obstructive pulmonary disease and subsequent risk of emergency department visits and hospitalizations for atrial fibrillation.
Although emerging evidence has suggested the relationship of chronic obstructive pulmonary disease with atrial fibrillation (AF), little is known about whether acute exacerbation of chronic obstructive pulmonary disease (AECOPD) increases the risk of repeated AF-related healthcare utilization. The investigators found that among patients with existing AF, AECOPD was associated with a higher risk of AF-related ED visit or hospitalization in the first 90-day post-AECOPD period.

Association between hospital financial distress and immediate breast reconstruction surgery after mastectomy among women with ductal carcinoma in situ.
Hospital financial distress may reduce the services a hospital can offer, particularly unprofitable ones. This study examined the association between hospital financial distress (HFD) and receipt of immediate breast reconstruction surgery after mastectomy among women diagnosed with ductal carcinoma in situ (DCIS). It concluded that the financial strength of the hospital where a patient receives treatment is associated with receipt of immediate breast reconstruction surgery.
