What Is the Effect of Organ Donation Authorization Rates When Utilizing a Standardized Effective Request Process?

To determine if implementation of a standardized effective request process (ERP) can increase organ donation authorization rates. DESIGN: A retrospective, observational study was performed using data acquired from the Midwest Transplant Network. chi-square test was used to analyze categorical data, with p value of less than 0.05 deemed significant. SETTING: The Midwest Transplant Network located in Westwood, KS from January 1, 2013 to June 30, 2017. PATIENTS: A total of 1,391 consecutive patients were identified as potential donors based on medical evaluation of the patient's neurologic status, organ function, and established age criteria. INTERVENTIONS: An ERP was used when discussing donation with 733 patients (53%), compared with no ERP usage with 658 patients (47%). MEASUREMENTS AND MAIN RESULTS: A significant increase (30%) in donation rates was observed when an ERP was used. A comparative decrease in donation rates was observed whenever a breakdown in any of the four identified steps occurred. LIMITATIONS: The data analyzed was gathered retrospectively. Due to the retrospective nature of our study, there is no way to determine delay in authorization times versus no delay. Although most population data information about the authorized donors was known, this information was limited in patients who declined. CONCLUSIONS: With proper preparation and planning, the implementation of a standardized ERP may improve organ donation rates and increase the number of life-saving organs for transplant.

Long-term mortality and causes of death among patients with mild traumatic brain injury: a 5-year multicenter study.

Objective: Undergoing mild traumatic brain injury (mTBI) increases mortality risk, but it is unclear what drives this finding. This study explored associations with mortality in patients with mTBI.Methods: This was a retrospective study of patients with mTBI and controls admitted to six level 1 trauma centers in 1/1/2009-12/31/2013. Mortality data were from the CDC National Death Index. Patients with mTBI were identified by ICD-9 code, Glasgow Coma Scale 13-15, Injury Severity Score (ISS) <16, and loss of consciousness ≤1 hour. Controls had hospital length of stay ≤24 hours, ISS<16, and no head injury.Results: This study included 964 patients with mTBI and 5,567 controls. mTBI was associated with a 47% increased 5-year mortality risk (HR = 1.47, 95% CL 1.08-2.01). Patients with mTBI were more likely to die of a neurodegenerative disease (17% vs 11%, P = .119). Cardiovascular (HR = 1.80, 95% CL 1.17-2.77), neurological (HR = 3.33, 95% CL 2.07-5.38), and respiratory (HR = 1.70, 95% CL 1.01-2.86) comorbidities were associated with mortality in patients with mTBI.Conclusions: Patients with mTBI are at increased mortality risk in the 5 years post-injury. Mortality in patients with mTBI was most influenced by preexisting conditions.

Modified version of the American College of Cardiology's recommendation for low-dose prothrombin complex concentrate is effective for warfarin reversal.

BACKGROUND: Dosing of four factor prothrombin complex concentrate (4PCC) for warfarin reversal remains controversial. Recently, the American College of Cardiology (ACC) recommended a low-dose PCC regimen as an option for warfarin reversal in acute major bleeding. We performed a retrospective study evaluating if a modified version of the ACC guideline recommendations was effective for warfarin reversal in acute major bleeds when compared to traditional variable dosing. METHODS: This was a retrospective cohort study of patients who received 4PCC for warfarin reversal in a 12 month period. We included patients that were ≥18 years of age, received 4PCC for warfarin reversal, and had an initial International Normalized Ratio (INR) of >2. Our primary outcome was the number of patients who had a post-4PCC infusion INR of <1.6. RESULTS: A total of 60 patients were included in the final analysis with 30 patients stratified to the traditional dosing and low-dose groups, respectively. Patient demographics were similar between both groups. We found no difference in the number of patients who had a post-4PCC infusion INR <1.6 between the traditional dosing and low dosing group (90.0% vs. 86.7%; p = 0.68). Additionally, we found no difference between post-infusion median INRs in each group (1.35 vs. 1.30; p = 0.16). Approximately 1000 units per patient were spared when utilizing the low-dose regimen. CONCLUSION: A modified version of the ACC's low-dose 4PCC option for warfarin reversal achieves similar outcomes for lowering INR values compared to traditional variable dosing regimens.

Lung ultrasound for detecting pneumothorax in injured children: preliminary experience at a community-based Level II pediatric trauma center.

BACKGROUND: Ultrasound (US) has been used in the adult trauma population with reported moderate to high sensitivities, but data are scarce in the pediatric trauma population. OBJECTIVE: The purpose of this study was to specifically examine the sensitivity and specificity of one lung US methodology (single-point anterior exam) in the pediatric trauma population when compared to chest radiography or CT. MATERIALS AND METHODS: We conducted a retrospective review of pediatric trauma patients who received lung US as an extension of the focused assessment with sonography for trauma (FAST) exam. We compared lung US findings with chest radiography and CT scans. RESULTS: Two hundred twenty-six pediatric trauma patients underwent lung US exam with confirmatory exams; 11 pneumothoraces (4.8%) were observed. Of those 11, 6 were evaluated as false negatives on the lung US. Analyses resulted in 45.5% sensitivity, 98.6% specificity and 96.0% accuracy. Pneumothoraces undetected by lung US were small and apical and were likely not observed because of their size and location. None of the false negatives required intervention. All true positives were associated with lung contusions. CONCLUSION: Pneumothorax is less common in the pediatric than the adult trauma population, and when encountered in children pneumothorax is often occult and might be associated with lung contusions. Existing evidence supports the usefulness of chest US in detecting pneumothorax in adults and suggests that it can be translated to injured children. However, our findings suggest that the sensitivity of lung US as a single-point anterior exam extension of the FAST exam might not be as reliable in the pediatric trauma population as in adults. Other methodologies using lung US might improve sensitivity.

A 360° Rotational Positioning Protocol of Organ Donors May Increase Lungs Available for Transplantation.

OBJECTIVES: To evaluate the improvement in lung donation and immediate lung function after the implementation of a 360° rotational positioning protocol within an organ procurement organization in the Midwest. DESIGN: Retrospective observational study. SETTING: The Midwest Transplant Network from 2005 to 2017. Rotational positioning of donors began in 2008. SUBJECTS: Potential deceased lung donors. INTERVENTIONS: A 360° rotational protocol. Presence of immediate lung function in recipients, change in PaO2:FIO2 ratio during donor management, initial and final PaO2:FIO2 ratio, and proportion of lungs donated were measured. Outcomes were compared between rotated and nonrotated donors. MEASUREMENTS AND MAIN RESULTS: A total of 693 donors were analyzed. The proportion of lung donations increased by 10%. The difference between initial PaO2:FIO2 ratio and final PaO2:FIO2 ratio was significantly different between rotated and nonrotated donors (36 ± 116 vs 104 ± 148; p < 0.001). Lungs transplanted from rotated donors had better immediate function than those from nonrotated donors (99.5% vs 68%; p < 0.001). CONCLUSIONS: There was a statistically significant increase in lung donations after implementing rotational positioning of deceased donors. Rotational positioning significantly increased the average difference in PaO2:FIO2 ratios. There was also superior lung function in the rotated group. The authors recommend that organ procurement organizations consider adopting a rotational positioning protocol for donors to increase the lungs available for transplantation.

Effect of platelet inhibition on bleeding complications in trauma patients on preinjury clopidogrel.

BACKGROUND: Use of antiplatelet medications for acute coronary syndromes and stroke prevention continues to rise as the population ages, although their effects on trauma outcomes remain unclear. This study sought to determine if trauma patients on preinjury clopidogrel with a higher degree of platelet inhibition (PI), as determined by the VerifyNow P2Y12 Test, experienced bleeding complications more frequently than did patients with a lower degree of PI. METHODS: Retrospective, cohort study of adult trauma patients admitted to a Level 1 trauma center between October 1, 2009, and August 31, 2011, with documentation of clopidogrel as a home medication. Patients were excluded if they did not receive the P2Y12 assay, had a platelet count at the time of assay less than 100 × 10/L, or had warfarin, dabigatran, or other thienopyridine therapy documented as a concomitant home medication. The primary outcome compared a composite of bleeding complications between patients with 20% PI or greater and those with less than 20% PI. Bleeding complications were defined as the progression of neurologic insult, postoperative hemorrhage or initiation of the institutional massive blood transfusion protocol. RESULTS: Baseline characteristics were similar between groups. The incidence of bleeding complications was not different between study groups (24.2% vs. 27.6%, p = 0.78). No difference in the secondary outcomes of length of stay, in-hospital mortality, and red blood cell transfusion were observed. Patients with 20% PI or greater received platelet transfusion more frequently than did patients with less than 20% PI (51.5% vs. 10.3%, p = 0.0008). CONCLUSION: The VerifyNow P2Y12 Test may be a tool to stratify trauma patients at a higher risk of bleeding and who subsequently may benefit from transfusion. More frequent platelet transfusion in patients with 20% PI or greater may have resulted in fewer bleeding complications, although confirmation in a prospective, randomized trial is warranted. LEVEL OF EVIDENCE: Prognostic study, level III.

Evaluation of process variations in noncompliance in the implementation of evidence-based sepsis care.

INTRODUCTION: Sepsis is recognized as an often-lethal disease. Recommended guidelines are complex and time sensitive. Response teams (RTs) have demonstrated success in implementation of quality initiatives. The purpose of this study was to evaluate variations in noncompliance with recommended sepsis guidelines overall and between a sepsis-focused RT and standard care. METHODS: This retrospective chart review categorized septic patients based on treatment by a sepsis response team (SRT) versus standard care (non-SRT). Guideline compliance was based upon the Surviving Sepsis evaluation and treatment guidelines. RESULTS: Patient records for 123 identified septic patients post first-year implementation were evaluated. Overall, compliance rates were low and there were variations in compliance between the treatment providers. The SRT was more compliant than the non-SRT. SRT noncompliance was more often due to failure to achieve therapeutic goals within the recommended time. Mortality benefit was not statistically significant between groups; however mortality was higher in the non-SRT group. CONCLUSION: Noncompliance is more complex than simple failure to initiate, especially in time-dependent therapies. The development and education of an RT demonstrates improvement in application of sepsis-focused therapies over standard care.

Conspicuous vs customary location of hand hygiene agent dispensers on alcohol-based hand hygiene product usage in an intensive care unit.

CONTEXT: Hand washing is considered the single most important nosocomial infection-control strategy, yet compliance rarely meets levels recommended by infection control authorities. OBJECTIVES: To determine whether placement of hand hygiene foam dispensers in more conspicuous positions and closer proximity to patients would increase use of infection control agents as measured by volume of product used. Further, to ascertain the influence of dispenser placement vs the number of dispensers available on usage by volume. METHODS: This prospective, observational study conducted in an intensive care unit was composed of three observation periods. A control period with standard agent dispenser location (8 dispensers) was followed by two experimental periods: (1) "conspicuous and immediate proximity to patient" placement (16 dispensers) and (2) standard locations with a dramatic increase in the number of dispensers (36 dispensers). RESULTS: Volume of use for alcohol-based hand hygiene agent during the three observation periods revealed a statistically significant increase in daily consumption after conspicuous and proximate positioning of dispensers (P<.001). However, increasing the number of dispensers did not increase agent use (P=.196). CONCLUSION: More conspicuous placement of dispensers containing alcohol-based hand hygiene agent (ie, immediate proximity to patients) resulted in statistically and clinically significant increases in product usage. An increase in the number of dispensers did not increase usage. The impact of dispenser positioning on usage by volume for these highly effective products should be considered when planning and implementing intensive care unit infection-control policies.

Outcomes of tube thoracostomies performed by advanced practice providers vs trauma surgeons.

BACKGROUND: The role of advanced registered nurse practitioners and physician assistants in emergency departments, trauma centers, and critical care is becoming more widely accepted. These personnel, collectively known as advanced practice providers, expand physicians' capabilities and are being increasingly recruited to provide care and perform invasive procedures that were previously performed exclusively by physicians. OBJECTIVES: To determine whether the quality of tube thoracostomies performed by advanced practice providers is comparable to that performed by trauma surgeons and to ascertain whether the complication rates attributable to tube thoracostomies differ on the basis of who performed the procedure. METHODS: Retrospective blinded reviews of patients' charts and radiographs were conducted to determine differences in quality indicators, complications, and outcomes of tube thoracostomies by practitioner type: trauma surgeons vs advanced practice providers. RESULTS: Differences between practitioner type in insertion complications, complications requiring additional interventions, hospital length of stay, and morbidity were not significant. The only significant difference was a complication related to placement of the tube: when the tube extended caudad, toward the feet, from the insertion site. Interrater reliability ranged from good to very good. CONCLUSIONS: Use of advanced practice providers provides consistent and quality tube thoracostomies. Employment of these practitioners may be a safe and reasonable solution for staffing trauma centers.

Percutaneous tracheostomy placement with external laser light transillumination identifies proper tracheal orientation and improves surgeon insertion confidence.

Complications of percutaneous tracheostomy include bleeding, loss of airway control, inadvertent injury to surrounding structures, and equipment damage, all of which can be attributed to poor visualization and inaccurate orientation. Initially, we performed percutaneous tracheostomy in the intensive care unit setting using the single-dilator technique with video bronchoscopy without external transillumination. During our first 30 procedures, the video bronchoscope was damaged in four instances, requiring costly repairs each time. To decrease the potential for uncertainty, loss of airway control, and equipment damage, the investigators developed a technique incorporating an external laser light source to transilluminate the trachea to accurately identify the correct and appropriate orientation. Since integration of the external transillumination technique, no additional video bronchoscopes have been damaged in 100 subsequent procedures. We conclude transillumination using an external laser light source is useful in identifying the tracheostomy insertion site. This tool decreases instrument damage and improves surgeon confidence during percutaneous tracheostomy placement.

Influence of semi-recumbent position on intra-abdominal pressure as measured by bladder pressure.

BACKGROUND: Intra-abdominal pressure (IAP) obtained by bladder pressure measurement is used to detect impending abdominal compartment syndrome (ACS), but, while it is recommended to use a supine position, the literature describes IAP measurement in varying positions. This study evaluated the impact of body position at differing head-of-bed (HOB) elevations on bladder pressure when planned to be used as a surrogate IAP measurement. MATERIALS AND METHODS: Forty-five trauma patients admitted to a surgical intensive care unit underwent bladder pressure measurements at 0, 15, 30, 45 degrees HOB position and 30 degrees HOB position plus 15 degrees of reverse Trendelenburg tilt; these measurements were performed in counterbalanced fashion and assessed by built-in angle indicators on the bed rails of each bed. Study participants were connected to an IAP monitoring kit via their indwelling Foley catheter. RESULTS: A total of 675 bladder pressure measurements were obtained with 135 measurements at each of five HOB elevations (0 degrees , 15 degrees , 30 degrees , 45 degrees , 30 degrees +15 degrees tilt). Statistically significant differences occurred between all HOB elevations. Statistically significance differences also occurred at different BMI statuses. CONCLUSIONS: Elevating HOB significantly increases bladder pressure measurement. Bladder pressure measurements in nonsupine positions may not provide valid interpretation for IAP, and more so in cases of increased body mass index.
