The Cost of Poverty: The Relationship Between Insurance Status, Length of Stay, and Discharge Disposition in Trauma Patients.

INTRODUCTION: Insurance status (IS) is known to be associated with length of stay (LOS). The impact of IS on excess LOS (ELOS), days between medical readiness and discharge date, has not been explored. METHODS: We conducted a retrospective study of patients with pelvic fractures at a level I trauma center. Outcomes included ELOS (primary), discharge disposition (secondary), and ELOS-associated complications (secondary). RESULTS: 185 patients were included. Uninsured patients were the youngest and had the least baseline comorbidities (31.3 years (median), Charlson Comorbidity Index (CCI) .1) while publicly insured patients were the oldest and had the most baseline comorbidities (58.4 years (median), CCI 2.32). Excess LOS and associated complications did not differ among groups. After regression analysis, UIPs had longer LOS than PRPs (2.07 days, 95% CI .28-3.85). UIPs were recommended to go to inpatient rehabilitation 51.6% of the time but were discharged home 93.6% of the time; 81.0% of these changes were attributed to insufficient financial resources. CONCLUSIONS: Excess LOS and complications associated with ELOS were not associated with IS. Although UIPs were younger and had fewer baseline comorbidities, they had longer LOS after regression analysis. While discharge recommendations differed based on insurance status, UIPs had limited access to rehabilitation due to financial disparities. Despite initial treatment team recommendations, UIPs had to be sent home as their lack of insurance precluded inpatient rehabilitation placement.

A Daily Checklist Method Increases Documentation of Code Status in Trauma Patients.

OBJECTIVES: While insufficient code status documentation (CSD) is a longstanding challenge, all patients deserve the opportunity to participate in decision-making regarding code status, especially trauma patients with an unpredictable course. Prior interventions to increase CSD relied on reminder systems. We hypothesize that introducing a daily checklist will increase CSD for patients in the trauma ICU. METHODS: This quality improvement study examined the efficacy of a twice-daily checklist for improving CSD in trauma patients at a level I trauma center. A pre-intervention (PRE) and post-intervention (POST) daily census characterized the percentage of patients with CSD (primary outcome), time-to-code status (TTCS, secondary outcome) documentation, and information about patients who were discharged with no code status (DNCS, secondary outcome). RESULTS: Of 213 PRE and 207 POST, daily census CSD for all patients increased from a median of 50.0% PRE to 64.4% POST (P < .05). Time-to-code status was halved (PRE: 25.30 h, POST: 12.71 h, P < .05). Code status documentation within 12 h increased from 41.8% PRE to 60.9% POST (P < .05). Overall, the percentage of patients with CSD during their hospitalization increased 20% (PRE: 63.8%, POST: 83.6%, P < .05). Discharged with no code status patients decreased 20% (PRE: 35.2%, POST: 15.5%, P < .05). CONCLUSION: Including code status in a daily checklist involving key aspects of care for trauma patients is an effective method for improving code status documentation. Capturing code status for more patients in trauma allows us to provide patient-centered, goal-concordant care.

Analysis of Need for Intervention in Low-Grade Traumatic Splenic Injury.

BACKGROUND: Blunt splenic injuries are common traumatic injuries. Severe injuries may require blood transfusion, procedural, or operative intervention. Conversely, patients with low-grade injuries and normal vital signs frequently do not require intervention. The level and duration of monitoring required to safely manage these patients are unclear. We hypothesize that low-grade splenic trauma has a low rate of intervention and may not require acute hospitalization. METHODS: This retrospective descriptive analysis included patients admitted to a level I trauma center with low injury burden (injury severity score <15) and The American Association for the Surgery of Trauma (AAST) grade 1 (G1) and 2 (G2) splenic injuries between January 2017 and December 2019 using the Trauma Registry of the American College of Surgeons (TRACS). The primary outcome was the need for any intervention. Secondary outcomes included time to intervention and length of stay. RESULTS: 107 patients met inclusion criteria. 87.9% required no intervention . 9.4% required blood products, with a median time to transfusion of 7.4 hours from arrival. All patients receiving blood products had extenuating circumstances such as bleeding from other injuries, anticoagulant use, or medical comorbidities. 2 patients required splenic artery embolization, one presenting with return precautions 9 days post-injury and 1 with significant comorbidities. One patient with concomitant bowel injury required splenectomy. CONCLUSIONS: Low-grade blunt splenic trauma has a low rate of intervention, which typically occurs within the first 12 hours of presentation. This suggests that outpatient management with return precautions may be appropriate for select patients after a short interval of observation.

Independent pathways control muscle tissue size and sarcomere remodeling.

Cell growth and proliferation must be balanced during development to attain a final adult size with the appropriate proportions of internal organs to maximize fitness and reproduction. While multiple signaling pathways coordinate Drosophila development, it is unclear how multi-organ communication within and between tissues converge to regulate systemic growth. One such growth pathway, mediated by insulin-like peptides that bind to and activate the insulin receptor in multiple target tissues, is a primary mediator of organismal size. Here we uncover a signaling role for the NUAK serine/threonine kinase in muscle tissue that impinges upon insulin pathway activity to limit overall body size, including a reduction in the growth of individual organs. In skeletal muscle tissue, manipulation of NUAK or insulin pathway components influences sarcomere number concomitant with modulation of thin and thick filament lengths, possibly by modulating the localization of Lasp, a nebulin repeat protein known to set thin filament length. This mode of sarcomere remodeling does not occur in other mutants that also exhibit smaller muscles, suggesting that a sensing mechanism exists in muscle tissue to regulate sarcomere growth that is independent of tissue size control.

A tissue communication network coordinating innate immune response during muscle stress.

Complex tissue communication networks function throughout an organism's lifespan to maintain tissue homeostasis. Using the genetic model Drosophila melanogaster, we have defined a network of immune responses that are activated following the induction of muscle stresses, including hypercontraction, detachment and oxidative stress. Of these stressors, loss of the genes that cause muscle detachment produced the strongest levels of JAK-STAT activation. In one of these mutants, fondue (fon), we also observe hemocyte recruitment and the accumulation of melanin at muscle attachment sites (MASs), indicating a broad involvement of innate immune responses upon muscle detachment. Loss of fon results in pathogen-independent Toll signaling in the fat body and increased expression of the Toll-dependent antimicrobial peptide Drosomycin. Interestingly, genetic interactions between fon and various Toll pathway components enhance muscle detachment. Finally, we show that JAK-STAT and Toll signaling are capable of reciprocal activation in larval tissues. We propose a model of tissue communication for the integration of immune responses at the local and systemic level in response to altered muscle physiology.
