Massive Hemothorax Caused by a Single Intercostal Artery Bleed Ten Days after Solitary Minimally Displaced Rib Fracture

Delayed hemothorax (DHX) following blunt thoracic trauma is a rare occurrence with an extremely variable incidence and time to diagnosis that is generally associated with clinically insignificant blood loss. In this report, we present a case of acute onset DHX ten days after a relatively mild traumatic event that resulted in a single minimally displaced rib fracture. The patient awoke from sleep suddenly with acute onset dyspnea and chest pain and reported to the emergency department (ED). The patient lost over six and a half liters of blood during the first 9 hours of his admission, the largest volume yet reported in the literature for DHX, which was eventually found to be due to a single intercostal artery bleed. Successful management in this case entailed two emergent thoracotomies and placement of multiple thoracostomy tubes to control blood loss. The patient was discharged home on postoperative day 5

Impact of affordable care act insurance expansion on pre-hospital access to care: Changes in adult perforated appendix admission rates after medicaid expansion and the dependent coverage provision

Background: The Affordable Care Act (ACA) changed the landscape of insurance coverage, allowing young adults to remain on their parents\u27 insurance until age 26 (Dependent Coverage Provision [DCP]) and states to optionally expand Medicaid up to 133% of the federal poverty level. Although both improved insurance coverage, little is known about the ACA\u27s impact on observed receipt of timely access to acute care. The objective of this study was to compare changes in insurance coverage and perforation rates among hospitalized adults with acute appendicitis after vs before Medicaid expansion and the DCP using an Agency for Healthcare Research and Quality (AHRQ)-certified metric designed to measure pre-hospital access to care.Study design: We performed a quasi-experimental, difference-in-difference (DID) analysis of 2008-2015 state-level inpatient claims.Results: Adults, aged 19 to 64, in expansion states experienced an absolute 7.7 percentage point decline in uninsured (95% CI 7.5 to 7.9) after Medicaid expansion compared with nonexpansion states. This coincided with a 5.4 percentage point drop in admissions for perforated appendicitis (95% CI 5.0 to 5.8) that was most pronounced among young adults, aged 26 to 34, just age-ineligible for the DCP (DID: 11.5 percentage points). Medicaid expansion insurance changes were 4.1 times larger than those encountered under the DCP (DID: 1.9). They affected all population subgroups and significantly reduced access-related disparities in race/ethnicity and lower-income communities. Although both Medicaid expansion and the DCP were associated with significant insurance gains, those attributable to the DCP were more concentrated among more privileged patients. Despite this trend, both policies resulted in larger reductions in perforation rates for historically uninsured and underserved groups.Conclusions: Reductions in uninsured after Medicaid expansion and the DCP were associated with significant reductions in perforated appendix admission rates. Improvements in access to acute surgical care suggest that maintained/continued insurance expansion could lead to fewer delays, better patient outcomes, and reductions in disparities among the most at-risk populations

Association of medicaid expansion with access to rehabilitative care in adult trauma patients

Importance: Trauma is a leading cause of death and disability for patients of all ages, many of whom are also among the most likely to be uninsured. Passage of the Patient Protection and Affordable Care Act was intended to improve access to care through improvements in insurance. However, despite nationally reported changes in the payer mix of patients, the extent of the law\u27s impact on insurance coverage among trauma patients is unknown, as is its success in improving trauma outcomes and promoting increased access to rehabilitation.Objective: To use rigorous quasi-experimental regression techniques to assess the extent of changes in insurance coverage, outcomes, and discharge to rehabilitation among adult trauma patients before and after Medicaid expansion and implementation of the remainder of the Patient Protection and Affordable Care Act.Design, setting, and participants: Quasi-experimental, difference-in-difference analysis assessed adult trauma patients aged 19 to 64 years in 5 Medicaid expansion (Colorado, Illinois, Minnesota, New Jersey, and New Mexico) and 4 nonexpansion (Florida, Nebraska, North Carolina, and Texas) states.Interventions/exposure: Policy implementation in January 2014.Main outcomes and measures: Changes in insurance coverage, outcomes (mortality, morbidity, failure to rescue, and length of stay), and discharge to rehabilitation.Results: A total of 283 878 patients from Medicaid expansion states and 285 851 patients from nonexpansion states were included (mean age [SD], 41.9 [14.1] years; 206 698 [36.3%] women). Adults with injuries in expansion states experienced a 13.7 percentage point decline in uninsured individuals (95% CI, 14.1-13.3; baseline: 22.7%) after Medicaid expansion compared with nonexpansion states. This coincided with a 7.4 percentage point increase in discharge to rehabilitation (95% CI, 7.0-7.8; baseline: 14.7%) that persisted across inpatient rehabilitation facilities (4.5 percentage points), home health agencies (2.9 percentage points), and skilled nursing facilities (1.0 percentage points). There was also a 2.6 percentage point drop in failure to rescue and a 0.84-day increase in average length of stay. Rehabilitation changes were most pronounced among patients eligible for rehabilitation coverage under the 2-midnight (8.4 percentage points) and 60% (10.2 percentage points) Medicaid payment rules. Medicaid expansion increased rehabilitation access for patients with the most severe injuries and conditions requiring postdischarge care (eg, pelvic fracture). It mitigated race/ethnicity-, age-, and sex-based disparities in which patients use rehabilitation.Conclusions and relevance: This multistate assessment demonstrated significant changes in insurance coverage and discharge to rehabilitation among adult trauma patients that were greater in Medicaid expansion than nonexpansion states. By targeting subgroups of the trauma population most likely to be uninsured, rehabilitation gains associated with Medicaid have the potential to improve survival and functional outcomes for more than 60 000 additional adult trauma patients nationally in expansion states
