ABSTRACT

BACKGROUND: Community-oriented primary health care is a health promotion model that includes community diagnosis of a targeted community. PURPOSE: This educational project aimed to develop and implement an innovative approach of applying the principles of evidence-based practice in the teaching of community diagnosis, where the class of nursing students serves as an example of community. METHODS: The method consisted of a lecture and an evidence-based simulation of community diagnosis based on data collection regarding the lifestyle and health behaviors of third-year nursing students from a 4-year academic nursing program (200 students; 90% response rate). RESULTS: The data analysis revealed insufficient consumption of fruits, vegetables, and unsweetened fluids; excessive consumption of red and processed meat; insufficient engagement in physical activity; high anxiety level; and sleep deprivation. CONCLUSIONS: This educational approach allowed an interactive presentation of community health diagnostic methodology as well as community health problem prioritization applying the principles of an evidence-based approach. The method also improves students' awareness of their health and makes them better ambassadors of promoting a healthy lifestyle.

ABSTRACT

Reflex human papilloma virus (HPV) testing with "atypical squamous cells, cannot exclude high-grade squamous lesion (ASC-H)" cytologic diagnosis is not recommended by American Society for Colposcopy and Cervical Pathology guidelines. Studies have shown human papillomavirus (HPV)-negative ASC-H patients of increased age are low risk for cervical intraepithelial neoplasia 2 or worse (CIN2+) lesions on colposcopic follow-up. We retrospectively assessed the efficacy of reflex HPV testing in postmenopausal women with ASC-H in the Los Angeles County hospitals and clinics in a 5-year period. Of a total 85 clinically postmenopausal women with ASC-H, 31 (36.5%) women were found to have CIN2+ lesions on follow-up biopsy and five of them were HPV-negative. Of the women with CIN2+ lesions and positive HPV, 13 (41.9%) were high-risk HPV (hrHPV) 16/18/45 positive and 13 (41.9%) were hrHPV-other subtype positive. Women with positive HPV had an over 3-fold increased risk of developing CIN2+ lesions (P = 0.008). Relative risk of hrHPV16/18/45 was 1.79-fold higher than that of hrHPV-other subtype. The positive predictive value and negative predictive value of hrHPV were 49.1% and 84.4%, respectively. CIN2+ detection rate in Hispanic women with positive hrHPV was higher than in non-Hispanic women (53.8% versus 35.7%). Overall, postmenopausal women with ASC-H cytology result and negative hrHPV were less likely to develop CIN2+ lesions, whereas about half of ASC-H postmenopausal women develop CIN2+ lesions if hrHPV positive, especially if hrHPV 16/18/45 positive. Therefore, triaging ASC-H postmenopausal women with cotesting or, ideally, hrHPV genotyping should be considered as optimal clinical practice to avoid overtreatment.

ABSTRACT

OBJECTIVE: We performed a comprehensive systematic review and meta-analysis comparing initiation of full solid diet (FSD) versus stepwise diet to better define the management of patients with mild acute pancreatitis (AP). METHODS: Electronic databases were searched through August 2, 2021 for trials comparing initial FSD versus stepwise advancement in patients with mild AP on length of hospital stay (LOHS). We stratified by whether diet was initiated early (within 24 h or immediately upon presence of bowel sounds). RESULTS: We identified seven RCTs that compared LOHS in AP patients who received initial oral intake with solid diet versus stepwise diet. Across the studies a total of 305 patients were randomized to immediate FSD and 308 patients to sequential advancement. Patients who were initiated on a FSD had a significant reduction in total LOHS (Standardized Mean Difference (SMD) -0.52 [95% CI -0.69, -0.36]). There was no difference in post refeeding abdominal pain, tolerance of diet, or necessity to cease diet between the two groups. Sub-analysis of three studies that initiated FSD early reduced total LOHS (OR -0.95 [95% CI -1.26, -0.65]) compared to those who received graded diet advancement as well as higher likelihood of tolerating the assigned diet (OR 6.8 [95% CI 1.2, 39.2]). CONCLUSIONS: Our meta-analysis shows that initiation of FSD reduces total LOHS in patients with mild AP and does not increase post refeeding abdominal pain. Though additional high-quality studies are needed, these findings support initial solid diet for AP and consideration of feeding within the first 24 h.

ABSTRACT

BACKGROUND: Relying on reference laboratories for HIV confirmation testing may lead to delays in treatment and can cause stress for patients who have positive HIV screening results. OBJECTIVE: To internalize HIV-1/HIV-2 antibody differentiation testing within the hospital laboratory. METHODS: We analytically verified an HIV antibody differentiation immunoassay and subsequently compared result turnaround times (TATs) for HIV antibody differentiation and HIV-1 qualitative RNA in the months before and after the test internalization. RESULTS: HIV antibody differentiation was successfully verified. TATs for HIV antibody differentiation and HIV-1 RNA significantly improved, from medians of 40.4 hours and 156.5 hours to medians of 17.7 hours and 56.5 hours, respectively, after the internalization. The 90th-percentile turnaround times declined by 72% and 44%, respectively. CONCLUSIONS: It is feasible for a hospital laboratory to verify HIV antibody-differentiation testing. Its implementation may considerably improve result TATs for the HIV diagnostic algorithm.

ABSTRACT

BACKGROUND: Both groups A and AB plasma have been approved for emergency-release transfusion in acutely bleeding trauma patients before blood grouping being performed. The safety profile associated with this practice has not been well characterized, particularly in patients requiring massive transfusion. METHODS: This secondary analysis of the Pragmatic, Randomized, Optimal Platelet and Plasma Ratios trial examined whether exposure to group A emergency-release plasma (ERP) was noninferior to group AB ERP. We also examined patients whose blood groups were compatible with group A ERP versus patients whose blood groups were incompatible with group A ERP. Outcomes included 30-day mortality and complication rates including systemic inflammatory response syndrome, infection, renal injury, pulmonary dysfunction, and thromboembolism. RESULTS: Of the 680 patients predicted to receive a massive transfusion, 584 (85.9%) received at least 1 U of ERP. Of the 584 patients analyzed, 462 (79.1%) received group AB and 122 (20.9%) received group A ERP. Using a hazard ratio (HR) of 1.35 as the noninferiority margin, transfusion with group A versus group AB ERP was not associated with increased thromboembolic rates (HR, 0.52; 95% confidence interval [CI], 0.31-0.90). Mortality (HR, 1.15; 95% CI, 0.91-1.45) and nonfatal complication rates (HR, 1.24; 95% CI, 0.87-1.77) were inconclusive. In the subgroup analysis, transfusion with incompatible ERP (group B or AB patients receiving group A ERP) was not associated with increased nonfatal complications (HR, 1.02; 95% CI, 0.80-1.30). There were no reported hemolytic transfusion reactions. CONCLUSION: The use of ERP is common in patients requiring massive transfusion and facilitates the rapid balanced resuscitation of patients who have sustained blood loss. Group A ERP is an acceptable option for patients requiring massive transfusion, especially if group AB ERP is not readily available. LEVEL OF EVIDENCE: Therapeutic/Care Management, level IV; Prognostic, level III.

ABSTRACT

BACKGROUND: Hypocalcemia is cited as a complication of massive transfusion. However, this is not well studied as a primary outcome in trauma patients. Our primary outcome was to determine if transfusion of packed red blood cells (pRBC) was an independent predictor of severe hypocalcemia (ionized calcium ≤ 3.6 mg/dL). METHODS: Retrospective, single-center study (01/2004-12/2014) including all trauma patients ≥ 18 yo presenting to the ED with an ionized calcium (iCa) level drawn. Variables extracted included demographics, interventions, outcomes, and iCa. Regression models identified independent risk factors for severe hypocalcemia (SH). RESULTS: Seven thousand four hundred and thirty-one included subjects, 716 (9.8%) developed SH within 48 h of admission. Median age: 39 (Range: 18-102), systolic blood pressure: 131 (IQR: 114-150), median Glasgow Coma Scale (GCS): 15 (IQR: 10-15), Injury Severity Score (ISS): 14 (IQR: 9-24). SH patients were more likely to have depressed GCS (13 vs 15, p < 0.0001), hypotension (23.2% vs 5.1%, p < 0.0001) and tachycardia (57.0% vs 41.9%, p < 0.0001) compared to non-SH patients. They also had higher emergency operative rate (71.8% vs 29%, p < 0.0001) and higher blood administration prior to minimum iCa [pRBC: (8 vs 0, p < 0.0001), FFP: (4 vs 0, p < 0.0001), platelet: (1 vs 0, p < 0.0001)]. Multivariable analysis revealed penetrating mechanism (AOR: 1.706), increased ISS (AOR: 1.029), and higher pRBC (AOR: 1.343) or FFP administered (AOR: 1.097) were independent predictors of SH. SH was an independent predictor of mortality (AOR: 2.658). Regression analysis identified a significantly higher risk of SH at pRBC + FFP administration of 4 units (AOR: 18.706, AUC:. 897 (0.884-0.909). CONCLUSION: Transfusion of pRBC is an independent predictor of SH and is associated with increased mortality. The predicted probability of SH increases as pRBC + FFP administration increases.

ABSTRACT

Over the past decade, the shift toward damage control surgery for bleeding trauma patients has come with an increased emphasis on optimal resuscitation. Two lifesaving priorities predominate: to quickly stop the bleed and effectively resuscitate the hemorrhagic shock. Blood is separated into components for efficient storage and distribution; however, bleeding patients require all components in a balanced ratio. A variety of blood products are available to surgeons, and these products have evolved over time. This review article describes the current standards for resuscitation of bleeding patients, including characteristics of all available products. The relevant details of blood donation and collection, blood banking, blood components, and future therapies are discussed, with the goal of guiding surgeons in their emergency transfusion practice.

ABSTRACT

We conducted a quality improvement project at a large public tertiary-care academic hospital to reduce reported hospital-acquired Clostridium difficile infection (CDI) rates. We introduced diagnostic stewardship and provider education, resulting in a 2-fold reduction in C. difficile nucleic acid amplification test (NAAT) orders and markedly lower hospital CDI rate.Infect Control Hosp Epidemiol 2018;39:734-736.

ABSTRACT

OBJECTIVES: The Pancreatitis Activity Scoring System (PASS) has been derived by an international group of experts via a modified Delphi process. Our aim was to perform an external validation study to assess for concordance of the PASS score with high face validity clinical outcomes and determine specific meaningful thresholds to assist in application of this scoring system in a large prospectively ascertained cohort. METHODS: We analyzed data from a prospective cohort study of consecutive patients admitted to the Los Angeles County Hospital between March 2015 and March 2017. Patients were identified using an emergency department paging system and electronic alert system. Comprehensive characterization included substance use history, pancreatitis etiology, biochemical profile, and detailed clinical course. We calculated the PASS score at admission, discharge, and at 12 h increments during the hospitalization. We performed several analyses to assess the relationship between the PASS score and outcomes at various points during hospitalization as well as following discharge. Using multivariable logistic regression analysis, we assessed the relationship between admission PASS score and risk of severe pancreatitis. PASS score performance was compared to established systems used to predict severe pancreatitis. Additional inpatient outcomes assessed included local complications, length of stay, development of systemic inflammatory response syndrome (SIRS), and intensive care unit (ICU) admission. We also assessed whether the PASS score at discharge was associated with early readmission (re-hospitalization for pancreatitis symptoms and complications within 30 days of discharge). RESULTS: A total of 439 patients were enrolled, their mean age was 42 (±15) years, and 53% were male. Admission PASS score >140 was associated with moderately severe and severe pancreatitis (OR 3.5 [95% CI 2.0, 6.3]), ICU admission (OR 4.9 [2.5, 9.4]), local complications (3.0 [1.6, 5.7]), and development of SIRS (OR 2.9 [1.8, 4.5]) as well as prolongation of hospitalization by a mean of 1.5 (1.3-1.7) days. For the prediction of moderately severe/severe pancreatitis, the PASS score (AUC = 0.71) was comparable to the more established Ranson's (AUC = 0.63), Glasgow (AUC = 0.72), Panc3 (AUC = 0.57), and HAPS (AUC = 0.54) scoring systems. Discharge PASS score >60 was associated with early readmission (OR 5.0 [2.4, 10.7]). CONCLUSIONS: The PASS score is associated with important clinical outcomes in acute pancreatitis. The ability of the score to forecast important clinical events at different points in the disease course suggests that it is a valid measure of activity in patients with acute pancreatitis.

ABSTRACT

INTRODUCTION: Higher transfusion ratios of plasma to packed red blood cells (PRBC) and platelets (PLT) to PRBC have been shown to be associated with decreased mortality in major trauma patients. However, little is known about the effect of transfusion ratios on mortality in patients with isolated severe traumatic brain injury (TBI). The aim of this study was to investigate the effect of transfusion ratios on mortality in patients with isolated severe blunt TBI. We hypothesized that higher transfusion ratios of plasma to PRBC and PLT to PRBC are associated with a lower mortality rate in these patients. METHODS: Retrospective observational study. Patients with isolated severe blunt TBI (AIS head≥3, AIS extracranial <3) admitted to an urban level I trauma centre were included. Clinical data were extracted from the institution's trauma registry, blood transfusion data from the blood bank database. The effect of higher transfusion ratios on in-hospital mortality was analysed using univariate and multivariable regression analysis. RESULTS: A total of 385 patients were included. Median age was 32 years (IQR 2-50), 71.4% were male, and 76.6% had an ISS≥16. Plasma:PRBC transfusion ratios≥1 were identified as an independent predictor for decreased in-hospital mortality (adjusted OR 0.43 [CI 0.22-0.81]). PLT:PRBC transfusion ratios≥1 were not significantly associated with mortality (adjusted OR 0.39 [CI 0.08-1.92]). CONCLUSION: This study revealed plasma to PRBC transfusion ratios≥1 as an independent predictor for decreased in-hospital mortality in patients with isolated severe blunt TBI.

ABSTRACT

BACKGROUND: Kidd blood group antibodies are notorious for transient detection and hemolytic transfusion reactions. This report compares the rate of detection of anti-Jka when using gel column agglutination versus solid-phase red blood cell adherence (SPRCA) testing and documents the occurrence of hemolytic transfusion reactions in 17 recently transfused patients who developed anti-Jka that were detectable by SPRCA but were undetectable by gel. STUDY DESIGN AND METHODS: Before April 20, 2011, the laboratory used gel column agglutination as the primary method for antibody screening and identification. From April 20, 2011, to August 12, 2013, SPRCA was adopted as the primary method for antibody screen with gel remaining the primary method for identification. SPRCA identification was also performed if sufficient sample was available. Medical records were reviewed for evidence of hemolytic reaction in patients whose anti-Jka was negative or inconclusive by gel, but clearly identifiable by SPRCA at the time the anti-Jka was first identified. RESULTS: A total of 105 patients were discovered with anti-Jka from 88,478 SPRCA screens performed. In 32 patients, anti-Jka was initially discovered by SPRCA testing and concurrent gel testing was completely negative (n = 26) or inconclusive (n = 6). Seventeen of the 32 patients were recently transfused and of these six met criteria for delayed hemolytic transfusion reaction (DHTR), three had possible DHTRs, and eight had delayed serologic reactions; 13 of the transfused patients received Jk(a-) RBCs to avoid potential hemolysis. CONCLUSION: SPRCA testing significantly increased the discovery of clinically significant anti-Jka and facilitated the earlier use of Jk(a-) RBCs to avoid hemolytic transfusion reactions.

ABSTRACT

BACKGROUND: There has been interest concerning patient outcomes when older red blood cell (RBC) components are utilized. Inventory management is key to maintaining a stock of fresher RBCs for general transfusion needs. We have altered our practice for RBC management to reduce RBC age at the time of transfusion. STUDY DESIGN AND METHODS: Retrospective review of RBC age at time of transfusion at a tertiary care hospital with active trauma service was performed. The baseline nonirradiated RBC inventory was decreased from 12 to 15 days of stock to 7 to 10 days of stock, with request made to the blood supplier for fresher RBCs, specified at 75% of RBCs less than 14 days old. The age of RBCs at time of receipt and at time of transfusion was tracked on a monthly basis for the next 12 months. RESULTS: The mean age of RBCs at transfusion was decreased by 9 days on average for the year. Significant decreases in the mean age of RBCs at transfusion were seen in the second half of the year, with 4 of 6 months seeing a mean age of less than 20 days. There were no documented incidences of hospital blood shortages after the reduction in inventory; no surgery was canceled or delayed because of inventory. CONCLUSION: Inventory age depends on active management, combined with vendor cooperation to receive fresher components. Reducing the age of RBC components transfused is possible without experiencing blood component shortages. Longer periods of observation may allow for further adjustment of stocking levels on a seasonal basis.

ABSTRACT

BACKGROUND: Traumatic coagulopathy (TC) occurs in 24% to 38% of adults and is associated with up to a six-fold increase in mortality. This study's purpose was to determine the incidence of pediatric TC and its impact on mortality. METHODS: A retrospective review (2004-2009) of all trauma patients from our Level I trauma center was performed. Coagulopathy was defined as an international normalized ratio of 1.5 or higher or activated partial thromboplastin time of more than 36 seconds or platelets less than 100,000/mm. Clinical outcomes were compared between pediatric (younger than 16 years) and adult patients (≥16 years or older). RESULTS: A total of 20,126 patients were identified (7.6% pediatric, 92.4% adult). Mean ± SD age was 8.7 ± 4.8 years for pediatric patients and 37.6 ± 16.7 years for adults. The incidence of admission coagulopathy was lower in children (5.8% vs. 8.4%; p < 0.001). Pediatric patients were less likely to develop coagulopathy (8.4% vs. 12.4%; p < 0.001) and developed coagulopathy later than adults (102.3 ± 123.2 hours vs. 59.2 ± 1,823.9 hours; p < 0.001). Traumatic brain injury (TBI) and non-TBI-related coagulopathy increased in stepwise fashion with age (up to 19.5% in elderly). Adult and pediatric TC was associated with increased mortality (pediatric: 14.4% vs. 0.5%; p = 0.02; adult: 18.3% vs. 1.8%; p < 0.001). CONCLUSIONS: Pediatric trauma patients are less likely to present with coagulopathy, are less likely to develop coagulopathy during their admission, and tend to develop coagulopathy later than adults. If they develop coagulopathy, however, mortality increases in a stepwise fashion with age and is associated with a two- to four-fold increased risk of death. LEVEL OF EVIDENCE: Epidemiologic study, level III.

ABSTRACT

OBJECTIVE: To examine non-specific red cell reactivity (NSR) on antibody (Ab) screening of obstetric inpatients. METHODS: Observational study of 5438 obstetric inpatients (2009-2013). Ab-positive patients were identified and their records reviewed for NSR, other antibodies, transfusion reactions or hemolytic disease of the fetus/newborn (HDFN). Evaluation of NSR frequency by test era assessed the impact of an institutional change to solid-phase screening in 2011. RESULTS: Of obstetric inpatients, 5.3% had at least one positive Ab screen; 1.6% had NSR. Of NSR-positive patients, 16.7% had identifiable Abs that pre-dated NSR; 25% had concurrent Abs and 8.5% had subsequent Ab identification. In 49.1%, NSR resolved during follow-up. The frequency of NSR was higher after the change to solid-phase Ab screening, but specific Ab frequency was similar in both testing periods. No transfusion reactions or cases of HDFN were noted in this cohort. CONCLUSIONS: NSR is found in 1-2% of obstetrical inpatients at our institution, and has more than doubled since the initiation of solid-phase screening. Although likely clinically insignificant by itself, NSR is commonly found in relation to other red cell Abs and may precede their development.

ABSTRACT

OBJECTIVE: The diagnosis of acute pancreatitis (AP) is defined as a constellation of abnormal pancreatic enzymes, imaging, and characteristic pain. The origin and clinical significance of isolated hyperlipasemia is unclear. METHODS: We prospectively evaluated patients with serum lipase level greater than 3 times the upper limit of normal (ULN) admitted to Los Angeles County Hospital from October 2014 to April 2015. Patients were identified by a daily laboratory query used to support an ongoing randomized trial of goal-directed therapy for AP (NCT 01761539). Nonpancreatic hyperlipasemia (NPHL) was defined as a serum lipase level greater than 3 times the ULN without characteristic pain or imaging. RESULTS: Among 221 patients with lipase level greater than 3 times the ULN, 170 met criterion for AP, and 51 did not. The leading etiologies for NPHL were decompensated cirrhosis and renal failure. Patients with NPHL were significantly older and had more comorbidities and lower serum lipase levels (360 ± 36 vs 1453 ± 135 IU/L, P < 0.001). There were no differences in length of hospitalization, intensive care unit admission, or mortality. CONCLUSIONS: Elevated serum lipase level has many nonpancreatic origins, with liver and renal failure being the most frequent. Distinct clinical features can help to differentiate between AP and NPHL.

ABSTRACT

Invasive candidiasis is associated with worse outcomes and increased mortality in critically ill patients. The Candida score (CS) provides a clinical tool for identifying patients at risk for invasive candidiasis. Outcomes of severely injured trauma patients with positive candida cultures stratified by their CS have not been well described. In this retrospective observational study, all severely injured trauma patients (Injury Severity Score ≥16) admitted to the Los Angeles County and University of Southern California Medical Center from April 2008 to April 2014 with positive Candida cultures were included. Outcomes of patients with a low risk for invasive candidiasis (CS < 3) were compared with those with a high risk (CS ≥ 3). A CS ≥ 3 was significantly associated with higher mortality (35.9% vs 5.0%, P = 0.001), longer length of stay (LOS) (median 49.0 vs 28.0, P = 0.002), longer intensive care unit LOS (35.0 vs 20.0, P < 0.001), requirement for renal replacement therapy (38.5% vs 4.9%, P < 0.001), and increased ventilator days (22.0 vs 12.0, P < 0.001). Multivariable regression analysis revealed a CS ≥ 3 as a significant predictor for increased mortality [OR 6.983], longer LOS [regression coefficient (RC) 1.572] and intensive care unit LOS (RC 1.698), more frequent need for renal replacement therapy (OR 13.268), and increased ventilator days (RC 1.836). In conclusion, a CS ≥ 3 is significantly associated with increased mortality and worse outcomes in severely injured trauma patients with positive Candida cultures. The CS thus may serve as a clinical tool to predict outcomes in this patient population.

BACKGROUND: Fetal-maternal hemorrhage is usually spontaneous and goes undetected but can be associated with adverse perinatal outcomes. CASE: We describe the detection of a fetal-maternal hemorrhage by abrupt disappearance of prophylactic anti-D on antibody screen in an Rh-negative mother with dichorionic twins admitted for atrial flutter of one twin. Both rosette and Kleihauer-Betke tests were positive. The diagnosis was confirmed by anemia in one twin at birth. CONCLUSION: Fetal-maternal hemorrhage requires a high index of suspicion for diagnosis. An unexpected sudden decline in Rh immune globulin-related anti-D may be an indication of fetal-maternal hemorrhage.

ABSTRACT

BACKGROUND: Hyperhemolysis in sickle cell disease is a rare and potentially life-threatening complication of transfusion. STUDY DESIGN AND METHODS: In this article we report a case of delayed hemolytic transfusion reaction with resultant hyperhemolysis triggered by an anti-IH autoantibody with alloantibody behavior. RESULTS: The anti-IH was reactive at room temperature as well as 37 °C, but only weakly reactive with autologous red blood cells. Initial cold agglutinin titer was 512. The profound, life-threatening, intravascular hemolysis was rapidly and dramatically reduced with the Complement 5 (C5) inhibitory antibody, eculizumab. The auto/allo cold agglutinin was subsequently suppressed with rituximab treatment. CONCLUSIONS: Eculizumab, a potent C5 inhibitory antibody, can be a rapid and effective therapy for hyperhemolytic transfusion reactions when given in a sufficient dose to fully block the activation of complement C5.

ABSTRACT

BACKGROUND: The Pragmatic, Randomized Optimal Platelets and Plasma Ratios (PROPPR) trial was a randomized clinical trial comparing survival after transfusion of two different blood component ratios for emergency resuscitation of traumatic massive hemorrhage. Transfusion services supporting the study were expected to provide thawed plasma, platelets, and red blood cells within 10 minutes of request. STUDY DESIGN AND METHODS: At the 12 Level 1 trauma centers participating in PROPPR, blood components transfused and delivery times were tabulated, with a focus on universal donor (UD) plasma management. The adequacy of site plans was assessed by comparing the bedside blood availability times to study goals and the new American College of Surgeons guidelines. RESULTS: Eleven of 12 sites were able to consistently deliver 6 units of thawed UD plasma to their trauma-receiving unit within 10 minutes and 12 units in 20 minutes. Three sites used blood group A plasma instead of AB for massive transfusion without complications. Approximately 4700 units of plasma were given to the 680 patients enrolled in the trial. No site experienced shortages of AB plasma that limited enrollment. Two of 12 sites reported wastage of thawed AB plasma approaching 25% of AB plasma prepared. CONCLUSION: Delivering UD plasma to massively hemorrhaging patients was accomplished consistently and rapidly and without excessive wastage in high-volume trauma centers. The American College of Surgeons Trauma Quality Improvement Program guidelines for massive transfusion protocol UD plasma availability are practicable in large academic trauma centers. Use of group A plasma in trauma resuscitation needs further study.
