Impact of 24/7 In-Hospital Intensivist Coverage on Outcomes in Pediatric Intensive Care. A Multicenter Study.

The around-the-clock presence of an in-house attending critical care physician (24/7 coverage) is purported to be associated with improved outcomes among high-risk children with critical illness. To evaluate the association of 24/7 in-house coverage with outcomes in children with critical illness. Patients younger than 18 years of age in the Virtual Pediatric Systems Database (2009-2014) were included. The main analysis was performed using generalized linear mixed effects multivariable regression models. In addition, multiple sensitivity analyses were performed to test the robustness of our findings. A total of 455,607 patients from 125 hospitals were included (24/7 group: 266,319 patients; no 24/7 group: 189,288 patients). After adjusting for patient and center characteristics, the 24/7 group was associated with lower mortality in the intensive care unit (ICU) (24/7 vs. no 24/7; odds ratio [OR], 0.52; 95% confidence interval [CI], 0.33-0.80; P = 0.002), a lower incidence of cardiac arrest (OR, 0.73; 95% CI, 0.54-0.99; P = 0.04), lower mortality after cardiac arrest (OR, 0.56; 95% CI, 0.340-0.93; P = 0.02), a shorter ICU stay (mean difference, -0.51 d; 95% CI, -0.93 to -0.09), and shorter duration of mechanical ventilation (mean difference, -0.68 d; 95% CI, -1.23 to -0.14). In this large observational study, we demonstrated that pediatric critical care provided in the ICUs staffed with a 24/7 intensivist presence is associated with improved overall patient survival and survival after cardiac arrest compared with patients treated in ICUs staffed with discretionary attending coverage. However, results from a few sensitivity analyses leave some ambiguity in these results.

Perceptions of Bedside Cardiac Critical Care Registered Nurses on 24 Hour Attending Intensivist Coverage.

To elicit the perceptions of bedside critical care nurses toward continual in-house attending coverage and its effect on patient safety, communication, and nursing education. A 5-point Likert-type questionnaire was designed to evaluate the perception of bedside nurses in the pediatric cardiac intensive care unit (PCICU) toward the presence of a 24 hour in-house attending physician. Single tertiary referral PCICU in Washington, DC SUBJECTS: The 46 PCICU nurses who participated in the study were separated into two groups based on exposure to the recent implementation of continual in-house attending coverage at our institution. Group one consisted of 14 nurses with only exposure to the new 24/7 in-house coverage while group two encompassed 32 nurses who had experienced both the new and old system (off-site on-demand attending physician). Surveys demonstrated that both groups found that the new system has a positive impact on nursing education (median score of 5) as well as a positive impact on the communication between multidisciplinary teams and between care team and families (median score of 5). Nurses who experienced only the new system scored one point lower (median score of 4) regarding the effect of this staffing model on patient outcomes than nurses who had experienced both systems (median score of 5, P = .016). Between 83% and 98% of all 46 nurses who participated indicated they agree or strongly agree with each of the questions regarding the benefit of 24 hour in-house attending coverage. Our study suggests that regardless of differences in experience, pediatric cardiac nurses believe the presence of an on-site intensivist to be beneficial to both nursing and patients.

Results of a National Radiology Attending Physician Survey: The Effects of In-House Late and Overnight Attending Coverage on Radiology Resident Training

Over the past 10 years, there has been increased attending-level image interpretation during what has typically been considered the on-call period. The purpose of this study is to survey radiology attending physicians and assess their perceptions about how the presence of radiology attending physicians during the on-call period affects patient care and resident education. Two hundred eighty-eight radiology attendings completed the online survey. 70% believe that after hours final reads by radiology attendings improves patient care. 56% believe that this additional attending presence has a negative impact on the ability of graduating residents to efficiently interpret studies independently. A majority of radiology attending physicians in this study believe that increased in-house radiology attending coverage is harming resident training across the United States, yet also believe this attending presence is important for patient care. Additional studies are needed to quantify and further evaluate this effect, and develop strategies to address potential negative impacts on radiology resident education.

Radiology 24/7 In-House Attending Coverage: Do Benefits Outweigh Cost?

Many radiology practices, including academic centers, are moving to in-house 24/7 attending coverage. This could be costly and may not be easily accepted by radiology trainees and attending radiologists. In this article, we evaluated the effects of 24/7 in-house attending coverage on patient care, costs, and qualitative aspects such as trainee education. We retrospectively collected report turnaround times (TAT) and work relative value units (wRVU). We compared these parameters between the years before and after the implementation of 24/7 in-house attending coverage. The cost to provide additional attending coverage was estimated from departmental financial reports. A qualitative survey of radiology residents and faculty was performed to study perceived effects on trainee education. There were decreases in report TAT following 24/7 attending implementation: 69% reduction in computed tomography, 43% reduction in diagnostic radiography, 7% reduction in magnetic resonance imaging, and 43% reduction in ultrasound. There was an average daytime wRVU decrease of 9%, although this was compounded by a decrease in total RVUs of the 2013 calendar year. The financial investment by the institution was estimated at $850,000. Qualitative data demonstrated overall positive feedback from trainees and faculty in radiology, although loss of independence was reported as a negative effect. TAT and wRVU metrics changed with implementation of 24/7 attending coverage, although these metrics do not directly relate to patient outcomes. Additional clinical benefits may include fewer discrepancies between preliminary and final reports that may improve emergency and inpatient department workflows and liability exposure. Radiologists reported the impression that clinicians appreciated 24/7 in-house attending coverage, particularly surgical specialists. Loss of trainee independence on call was a perceived disadvantage of 24/7 attending coverage and raised a concern that residency education outcomes could be adversely affected.

Increased Occurrence of Tracheal Intubation–Associated Events During Nights and Weekends in the PICU*

Adverse tracheal intubation-associated events are common in PICUs. Prior studies suggest provider and practice factors are important contributors to tracheal intubation-associated events. Little is known about how the incidence of tracheal intubation-associated events is affected by the time of day, day of the week, or presence of in-hospital attending-level intensivists. We hypothesize that tracheal intubations occurring during nights and weekends are associated with a higher frequency of tracheal intubation-associated events. Retrospective observational cohort study. Twenty international PICUs. Critically ill children requiring tracheal intubation. None. We analyzed 5,096 tracheal intubation courses from July 2010 to March 2014 from the prospective multicenter National Emergency Airway Registry for Children. Frequency of a priori-defined tracheal intubation-associated events was the primary outcome. Occurrence of any tracheal intubation-associated events and severe tracheal intubation-associated events were more common during nights (19:00 to 06:59) and weekends compared with weekdays (19% vs 16%, p = 0.01; 7% vs 6%, p = 0.05, respectively). This difference was significant in emergent intubations after adjusting for site-level clustering and patient factors: for any tracheal intubation-associated events: adjusted odds ratio, 1.20; 95% CI, 1.02-1.41; p = 0.03; but not significant in nonemergent intubations: adjusted odds ratio, 0.94; 95% CI, 0.63-1.40; p = 0.75. For emergent intubations, PICUs with home-call attending coverage had a significantly higher frequency of tracheal intubation-associated events during nights and weekends (adjusted odds ratio, 1.29; 95% CI, 1.01-1.66; p = 0.04), and this difference was attenuated in PICUs with in-hospital attending coverage (adjusted odds ratio, 1.12; 95% CI, 0.91-1.39; p = 0.28). Higher occurrence of tracheal intubation-associated events was observed during nights and weekends. This difference was primarily attributed to emergent intubations. In- hospital attending physician coverage attenuated this discrepancy between weekdays versus nights and weekends but was not fully protective for tracheal intubation-associated events.

Results of the 2015 Survey of the American Alliance of Academic Chief Residents in Radiology

The American Alliance of Academic Chief Residents in Radiology conducts an annual survey of chief residents in Diagnostic Radiology programs in North America. The survey serves as a resource for observing trends and disseminating ideas among radiology training programs. An online survey was distributed to chief residents at 181 residency programs, with questions on a broad range of topics including resident benefits, program and call structure, American Board of Radiology Core exam preparation, fellowships, and the job market. A total of 193 individual responses were received from 120 programs, for a response rate of 66%. The responses were compared to data from prior years' surveys, principally from 2012 to 2014. Programs are shifting resident benefits spending toward Core exam preparation resources and away from lead aprons. In addition, 24-hour attending coverage continues to spread among programs, and the fraction of programs providing face-to-face postcall readouts continues to decline. Finally, although resident perception of the job market is now improving, residents feel that the job market continues to discourage medical students from entering radiology, a fact borne out by the 2015 match results. How the upcoming change to a direct interventional radiology residency will affect medical student interest is as yet uncertain.

Perceptions of 24/7 In-house Attending Coverage on Fellow Education and Autonomy in a Pediatric Cardiothoracic Intensive Care Unit.

The 24/7 in-house attending coverage is emerging as the standard of care in intensive care units. Implementation costs, workforce feasibility, and patient outcomes resulting from changes in physician staffing are widely debated topics. Understanding the impact of staffing models on the learning environment for medical trainees and faculty is equally warranted, particularly with respect to trainee education and autonomy. This study aims to elicit the perceptions of pediatric cardiology fellows and attendings toward 24/7 in-house attending coverage and its effect on fellow education and autonomy. We surveyed pediatric cardiology fellows and attendings practicing in the pediatric cardiothoracic intensive care unit (PCTU) of a large, university-affiliated medical center, using structured Likert response items and open-ended questions, prior to and following the transition to 24/7 in-house attending coverage. All (100%) trainees and faculty completed all surveys. Both prior to and following transition to 24/7 in-house attending coverage, all fellows, and the majority of attendings agreed that the overnight call experience benefited fellow education. At baseline, trainees identified limited circumstances in which on-site attending coverage would be critical. Preimplementation concerns that 24/7 in-house attending coverage would negatively affect the education of fellows were not reflected following actual implementation of the new staffing policy. However, based upon open-ended questions, fellow autonomy was affected by the new paradigm, with fellows and attendings reporting decreased "appropriateness" of autonomy after implementation. Our prospective study, showing initial concerns about limiting the learning environment in transitioning to 24/7 in-house attending coverage did not result in diminished perceptions of the educational experience for our fellows but revealed an expected decrease in fellow autonomy. The study indirectly facilitated open discussions about methods to preserve fellow education and warranted autonomy in our PCTU; however, continued efforts are needed to achieve the optimal balance between supervised training and the transition to autonomous practice.

Changes in inpatient staffing following implementation of new residency work hours.

In 2011, the Accreditation Council for Graduate Medical Education added additional resident work-hour restrictions that limited the number of hours residents could work, with increased emphasis on attending supervision. Our objective was to determine how residency programs have responded to residency work hours, specifically assessing residency night float systems and in-house attending physicians. In May 2012, an electronic survey was sent to all US pediatric residency training programs via the Association of Pediatric Program Directors listserv with e-mail reminders to nonresponding programs. We analyzed data to assess the use of resident night float systems, admission caps, and attending physicians in-house at night. Out of 198 programs contacted, 152 programs responded (77% response rate). Residency programs utilizing a night float system increased from 43% to 71% after new work hours were implemented. Overall use of resident admission caps did not change significantly. Twenty-three percent of programs increased the number of attending physicians in-house at night; 57% of those programs increased the number of pediatric hospitalist attendings, whereas 37% increased the number of pediatric intensivists. There is a trend toward increased pediatric hospitalist attending in-house 24/7 coverage. Of programs without 24/7 coverage, 26% plan to add coverage within 5 years. Only 12% of programs have no in-house attending coverage at night. Although programs vary in their response to changes in residency work restrictions, they most commonly utilize night float systems and increased the amount of in-house attending coverage at night, especially pediatric hospitalist attendings. Many programs plan to add 24/7 pediatric hospitalist coverage within 5 years.

The impact of on-site attending radiologist overnight coverage on radiology resident learning: a preliminary assessment

The objective of this study is to assess the impact of on-site attending radiologist overnight coverage on resident education during transition to 24/7 attending coverage. The study was exempted from IRB review. An anonymous survey was sent to 9 second year radiology residents who completed their first night call rotation (NC) with an attending radiologist (group 1) and 18 residents who completed their first NC prior to overnight attending coverage (group 2). This addressed anxiety level prior to NC, work pace, autonomy and confidence, and attending feedback, with responses graded on a five-point scale. Statistical analysis was performed using Spearman's rho correlation coefficient. Diagnostic Radiology In-Training (DXIT(TM)) exam scores were collected prior to and following completion of the NC rotation, and results were compared. Case volume before and after the transition was recorded. p value <0.05 indicated statistical significance. Eight out of nine residents in group 1 and 16 out of/18 residents in group 2 completed the survey. Group 1 was more likely to report working at a comfortable pace (p = 0.008) and receiving attending feedback (p = 0.004) than group 2. A non-significant trend towards reduced anxiety prior to NC was present in group 1 (p = 0.077). No difference in independence (p = 0.918), autonomy (p = 0.635), or confidence during (p = 0.431) or after NC (p = 1.00) was identified. DXIT(TM) scores were not significantly different between the two groups (p = 0.396). While overall case volume dictated by residents increased, fewer plain radiographs were dictated. Overnight attending coverage provides a more comfortable pace of study interpretation and increased attending feedback without decreasing resident independence or DXIT(TM) scores. Plain radiograph interpretation may need to be further emphasized.

The Relationship Between In-House Attending Coverage and Nighttime Extubation Following Congenital Heart Surgery*

Many cardiac ICUs have instituted 24/7 attending physician in-house coverage, which theoretically may allow for more expeditious weaning from ventilation and extubation. We aimed to determine whether this staffing strategy impacts rates of nighttime extubation and duration of mechanical ventilation. National data were obtained from the Virtual PICU System database for all patients admitted to the cardiac ICU following congenital heart surgery in 2011 who required postoperative mechanical ventilation. Contemporaneous data from our local institution were collected in addition to the Virtual PICU System data. The combined dataset (n = 2,429) was divided based on the type of nighttime staffing model in order to compare rates of nighttime extubation and duration of mechanical ventilation between units that used an in-house attending staffing strategy and those that employed nighttime residents, fellows, or midlevel providers only. Institutions that currently use 24/7 in-house attending coverage did not demonstrate statistically significant differences in rates of nighttime extubation or the duration of mechanical ventilation in comparison to units without in-house attendings. Younger patients cared for in non-in-house attending units were more likely to require reintubation. Pediatric patients who have undergone congenital heart surgery can be safely and effectively extubated without the routine presence of an attending physician. The utilization of nighttime in-house attending coverage does not appear to have significant benefits on the rate of nighttime extubation and may not reduce the duration of mechanical ventilation in units that already use in-house residents, fellows, or other midlevel providers.

Pediatric Code Events

A change in our children's hospital coverage model to providing full-time in-house supervision by intensivists allowed us to evaluate the impact of this change on patient safety outcomes. Our aim was to determine whether in-house attending coverage influenced the prevalence and outcomes of pediatric code events. We conducted a retrospective review of all code events between October 2005 and October 2007 (before in-house intensivist supervision) and compared the prevalence, interventions, and outcomes of these codes with those occurring between April 2008 and April 2010 (after in-house intensivist supervision). A code event was defined as any activation of the code system. One hundred eighty-seven bed children's hospital. All children with code events. None. There were 99 codes during these two periods: 39 codes occurring prior to in-house intensivist coverage (of which eight on the ward and 31 in the ICU) and 60 occurring following in-house attending coverage (30 on the ward and 30 in the ICU). Survival was significantly improved following the implementation of in-house coverage (odds ratio, 4.3; 95% CI, 1.7-10.8; p = 0.003). There was no significant change in the overall rate of codes during these two periods (0.82 codes/1,000 patient-days before implementation vs 1.17 codes/1,000 patient-days after implementation). However, there were significantly more codes on the ward following in-house intensivist coverage (0.2 codes/1,000 patient-days before implementation vs 0.71 codes/1,000 patient-days after implementation; p = 0.013). An intensivist was significantly more likely to be present during these events (odds ratio, 28; 95% CI, 3-273; p = 0.001); however, the acuity of the children with codes on the ward was significantly lower during the in-house coverage period (p = 0.001). There were no changes in the rate or outcomes of codes occurring in the ICU with this change in coverage. In the period following implementation of in-house intensivist supervision, children with code events were more likely to survive to hospital discharge. Having an intensivist in-house 24 hr/d, 7 d/wk may be associated with improved outcomes in hospitalized children.

A Randomized Trial of Nighttime Physician Staffing in an Intensive Care Unit: Kerlin MP, Small DS, Cooney E, et al. N Engl J Med 2013; 368:2201–9.

Intensive care units (ICUs) are increasingly seeking 24-h attending intensivist coverage. Although intuitively it would seem that increased attending coverage would improve patient outcomes, this has yet to be studied. To study this effect, the authors at a single academic medical ICU conducted a 1-year randomized study in which attending intensivists were scheduled to work a block of seven consecutive overnight shifts (to encompass 24-h coverage) vs. standard staffing (resident coverage with attending/fellow available by telephone).

Tempering pediatric hospitalist supervision of residents improves admission process efficiency without decreasing quality of care.

Many academic pediatric hospital medicine (PHM) divisions have recently increased in-house supervision of residents, often providing 24/7 in-house attending coverage. Contrary to this trend, we removed mandated PHM attending input during the admission process. We present an evaluation of this process change. This cohort study compared outcomes between patients admitted to the PHM service before (July 1, 2011-September 30, 2011) and after (July 1, 2012-September 30, 2012) the process change. We evaluated time from admission request to inpatient orders, length of stay (LOS), frequency of change in antibiotic choice, and rapid response team (RRT) calls within 24 hours of admission. Data were obtained via chart abstraction and from administrative databases. Wilcoxon rank sum and Fisher exact tests were used for analysis. We identified 182 and 210 admissions in the before and after cohorts, respectively. Median time between emergency department admission request and inpatient orders was significantly shorter after the change (123 vs 62 minutes, P < 0.001). We found no significant difference in LOS, the number of changes to initial resident antibiotic choice, standard of care, or RRTs called within the first 24 hours of admission. Removing mandated attending input in decision making for PHM admissions significantly decreased time to inpatient resident admission orders without a change in measurable clinical outcomes.

The Educational Impact of In-House Attending Coverage Models in the Pediatric ICU

The Educational Impact of In-House Attending Coverage Models in the Pediatric ICU

Results of the 2012 Survey of the American Association of Academic Chief Residents in Radiology

Every year, the American Association of Academic Chief Residents in Radiology conducts a survey of the chief residents in accredited radiology training programs in North America. The survey serves as a tool for gathering information, sharing ideas, and voicing opinions. An online survey was made available to the chief residents from 187 training programs in North America. Questions were presented in multiple-choice and free response formats, designed to address many issues ranging from program structure to on-call policies, changes for the new board examination format and fellowships, and the effects of health care reform on radiology practices. The results of the survey were tabulated and responses to the repeated questions were compared with those from earlier surveys dating to 2003. Among those surveyed, 185 individual responses representing 135 unique programs were completed, yielding a 73% response rate. Thirty-eight percent of programs responded from the northeast and 17% of programs responded from the southeast. Nineteen percent of responses were from central United States, 14% of responses were from western United States, and 12% of responses were from Canada. There is an increasing number of programs, which cover more hospitals, during the past decade. There are more programs providing ultrasound and magnetic resonance services after hours, with an associated increase in after-hours attending physician coverage. Many changes are being made for the future board examination format. Health care reform is affecting how residents are preparing themselves for their future practices.

The impact of 24-hr, in-hospital pediatric critical care attending physician presence on process of care and patient outcomes*

Attending physicians are only required to provide in-hospital coverage during daytime hours in many pediatric intensive care units. An in-hospital 24-hr pediatric intensive care unit attending coverage model has been increasingly popular, but the impact of 24-hr, in-hospital attending coverage on care processes and outcomes has not been reported. We compared processes of care and outcomes before and after the implementation of a 24-hr in-hospital pediatric intensive care unit attending physician model. Retrospective comparison of before and after cohorts. A single large, academic tertiary medical/surgical pediatric intensive care unit. : Pediatric intensive care unit admissions in 2000-2006. Transition to 24-hr from 12-hr in-hospital pediatric critical care attending physician coverage model in January 2004. A total of 18,702 patients were admitted to intensive care unit: 8,520 in 24 hrs; 10,182 in 12 hrs. Duration of mechanical ventilation was lower (median 33 hrs [interquartile range 12-88] vs. 48 hrs [interquartile range 16-133], adjusted reduction of 35% [95% confidence interval 25%-44%], p < .001) and intensive care unit length of stay was shorter (median 2 days [interquartile range 1-4] vs. 2 days [interquartile range 1-5], adjusted p < .001) for 24 hr vs. 12 hr coverage. The reduction in mechanical ventilation hours was similar when noninvasive, mechanical ventilation was included in ventilation hours (median 42 hrs vs. 56 hrs, adjusted reduction in ventilation hours: 33% [95% confidence interval 20-45], p < .001). Intensive care unit mortality was not significantly different (2.2% vs. 2.5%, adjusted p =.23). These associations were consistent across daytime and nighttime admissions, weekend and weekday admissions, and among subgroups with higher Pediatric Risk of Mortality III scores, postsurgical patients, and histories of previous intensive care unit admission. Implementation of 24-hr in-hospital pediatric critical care attending coverage was associated with shorter duration of mechanical ventilation and shorter length of intensive care unit stay. After accounting for potential confounders, this finding was consistent across a broad spectrum of critically ill children.

Abstract 176: Regional Stroke Networks May Fill Gaps for Community and Quality Improvement

Introduction: State departments of health (DOH) and professional organizations such as the American Heart Association (AHA) create guidelines that influence many aspects of the stroke systems of care (SSC); however, they do not directly address ongoing quality improvement (QI) efforts and community/professional education (CE) activities. Regional networks such as The NorthEast Cerebrovascular Consortium (NECC) may better liaise with hospitals to fill this gap. We assessed current adherence with recommended stroke improvement activities in the NECC and the attributed source (Joint Commission (JC), hospital QI, AHA, The NECC, and Get With the Guidelines-Stroke [GWTG-S®]) on performing these activities. Methods: Surveys were completed by 37% (172/471) of acute care hospitals in the Northeast region and 100% (8/8) DOH regarding hospital capacity, stroke center designation (SCD), and SSC programs. Respondents used a Likert scale of 1-5 (5=strongly agree) to rate influence of state SC mandates; Joint Commission (JC), hospital QI, AHA, The NECC, and GWTG-S® recommendations on their practices. Results: Over 80% of hospitals offer smoking cessation counseling, blood pressure screening, and rehabilitation, attributing AHA guidelines as most influential for these programs (mean=4.2). Less than 2/3rds of hospitals sponsor outreach programs to community organizations, whereas 83% target emergency medical services. Hospitals with an increase in thrombolytic use over the past 5 years attribute this largely to attending level acute stroke team coverage, again influenced by the AHA (mean=4.0). Among 167 reported SSC areas needing improvement, 56 (34%) identified gaps in QI (compliance, provider education and feedback) and 29 (17%) in CE. Conclusions: Though AHA and DOH guidelines are well incorporated into hospital practice, enforcement of standards, CE and QI processes are needed. Regional organizations such as the NECC are well poised to fill this gap through in-person collaboration and meetings of local stakeholders.

Pediatric Code Events: Does In-House Intensivist Supervision Improve Outcomes?

PURPOSE: A change in our children's hospital coverage model to providing full-time in-house supervision by intensivists allowed us to evaluate the impact of this change on patient safety outcomes. Our aim was to determine whether in-house attending coverage influenced the incidence and outcomes of pediatric code events.

Evolving a Successful Acute Care Surgical/Surgical Critical Care Group at a Nontrauma Hospital

A large acute care but nontrauma teaching hospital in Manhattan, New York performing 24 000 operations/year has evolved a Surgical Intensive Care Unit (SICU) Service with 3 attendings and 5 physician assistants over 9 years. The division follows nationally recognized, published best practices in shock, sepsis, ventilator management, nutrition, and antibiotic use and has maintained a total mortality of 1.9% (varying between 1.5% and 2.1%) for 9 years. Although PGY-1 and PGY-2 residents rotate through SICU, the division relies heavily on experienced, Fundamentals of Critical Care Support–trained physician assistants for organized consultation and ensuring adherence to best practices in daily patient care. For the past 4 years, the division has provided 24/7 in-house attending coverage in collaboration with the Division of Cardiac Surgery. In-house attending intensivist/cardiac surgeon coverage did not improve mortality. The division also provides approximately one third of the institution’s acute care surgery in rotation/collaboration with general surgeons. The practicalities of the division’s evolution and recommendations are discussed.

The status of massive transfusion protocols in United States trauma centers: massive transfusion or massive confusion?

Massive transfusion protocol (MTP) utilization and makeup is unknown. A Web-based survey was sent to members of the Eastern Association for the Surgery of Trauma and published in the American Association for the Surgery of Trauma newsletter. Comparisons were made with chi-square and logistic regression. A total of 186 surgeons and 59 center directors responded. To avoid bias, directors' responses are reported. Sixty percent annually admit more than 1500 patients. Sixty-seven percent had in-house attending coverage and 85% had a MTP. Presence of a MTP was not predicted by institution size, level, residency status, or admissions. Sixty-five percent of MTPs had been in place less than 5 years with 18% less than 1 year. Designs varied: 23% had one batch of components, 25% had two or three, 41% had more than three, and 11% did not use batches. Only 62% of first batches contained fresh-frozen plasma (FFP). In the second batch 98% had FFP. All third boxes had FFP. A ratio of FFP : red blood cells (RBCs) of less than 1 in the first batch predicted a ratio less than 1 in the second batch (p = 0.013). Twenty-seven percent had blood stored in the emergency department and 14% in the operating room. Twenty-four percent of MTPs autoactivate and 80% are trauma surgeon activated, 66% by the anesthesia staff, 32% by other surgeons, and 17% by the blood bank. Trauma surgeons activate the MTP most. Most centers have a MTP. Protocols are variable and new, and half have a 1:1 FFP : RBC ratio. Protocols with fewer initial units of FFP compared to RBCs maintain this.
