Black hip fracture patients experience worse health outcomes than otherwise similar White patients, but causes of these disparities are not known. We sought to determine if delays in hip fracture surgery and/or hospital structures contribute to racial disparities in hip fracture outcomes.

Using 2006 to 2016 Trauma Quality Program Public Use Files, we identified hip fracture patients with primary mechanisms of fall from standing and determined surgical treatment category (no surgery, surgery within 24 hours after arrival, surgery 24-48 hours after arrival, surgery more than 48 hours after arrival) as well as hospital structure characteristics (trauma center designation, teaching status, profit status, bed size). We used generalized structural equation models to conduct path analyses and determine if hip fracture treatment and hospital characteristics mediated the relationship between race (non-Hispanic Black/non-Hispanic White) and outcomes (complications, length of stay, disposition).

Non-Hispanic Black patients were more likely than non-Hispanic White patients to receive treatment at an academic medical center (49.1% vs. 28.0%), at a hospital with >600 inpatient beds (39.5% vs. 25.3%), and at a level I or II trauma center (86.8% vs. 77.7%); were more likely to go without hip fracture repair surgery (22.8% vs. 21.4%); and were more likely to have delayed surgery >48 hours after hospital arrival (15.5% vs. 10.6%). Adenosine disodium triphosphate solubility dmso Path analysis suggests hip fracture treatment group and hospital characteristics mediate the relationship with complications, length of stay, and disposition.

Non-Hispanic Black patients with fall-related hip fracture are more likely to experience delays in care, complications, and longer inpatient stays. Hospital characteristics contribute to increased risk of complications and longer length of stay, both as independent determinants of outcomes and as determinants of delays in hip fracture surgery.

Acute care surgery (ACS) model of care delivery has many benefits. However, since the ACS surgeon has limited control over the volume, timing, and complexity of cases, traditional metrics of operating room (OR) efficiency almost always measure ACS service as "inefficient." The current study examines an alternative method-performance fronts-of evaluating changes in efficiency and tests the following hypotheses (1) in an institution with a robust ACS service, performance front methodology is superior to traditional metrics in evaluating OR throughput/efficiency, and (2) introduction of an ACS service with block time allocation will improve OR throughput/efficiency.

Operating room metrics 1-year pre-ACS implementation and post-ACS implementation were collected. Overall OR efficiency was calculated by mean case volumes for the entire OR and ACS and general surgery (GS) services individually. Detailed analysis of these two specific services was performed by gathering median monthly minutes-in block, out of blon OR for the ACS service improves overall throughput/efficiency.
In an institution with a busy ACS service, the alternative fronts methodology offers a more accurate evaluation of OR efficiency. The provision of an OR for the ACS service improves overall throughput/efficiency.
Forty percent of critically ill trauma patients will develop an infectious complication. Pneumonia is the most common cause of death of trauma patients surviving their initial insult. We previously demonstrated that polytrauma (PT), defined as two or more severe injuries in at least two areas of the body, induces emergency hematopoiesis characterized by accelerated myelopoiesis in the bone marrow and increased myeloid cell frequency in the peripheral tissues. We hypothesized that PT alone induces priming of neutrophils, resulting in hyperactivation upon secondary exposure to bacteria and causing acute lung injury and increased susceptibility to secondary exposure to Pseudomonas aeruginosa pneumonia.

C57BL/6 mice were subjected to PT consisting of a lower extremity pseudofracture, liver crush injury, and 15% blood-volume hemorrhage. Pneumonia was induced by intratracheal injection of 5 × 106 CFU live P. aeruginosa or 1 × 107 of heat-killed P. aeruginosa (HKPA). For reactive oxygen species (ROS), studies poeumonia. These results suggest that trauma-induced immune dysfunction can cause immunopathologic response to secondary infection and suggests neutrophil-mediated pulmonary damage as a therapeutic target for posttrauma pneumonia.

We examined the association of organizational justice (i.e., procedural justice and interactional justice) with cognitive failures, and the mediation effect of psychological distress on this association in Japanese employees.

A total of 189 men and 35 women from two sites of a manufacturing company in Japan were surveyed using a self-administered web-based questionnaire. A multiple mediation analysis was conducted.

A significant negative total effect of procedural justice on cognitive failures was observed (c = -0.180 [95% confidence interval -0.315 to -0.044]). Furthermore, the mediation effect of psychological distress was significant (c-c' = - 0.213 [95% confidence interval -0.323 to -0.115]). Similar patterns were observed for interactional justice.

Employees may be more likely to experience cognitive failures in daily activities in work settings where organizational justice is lower, which seems to be explained by psychological distress.
