Interhospital Transfer Delays Appropriate Treatment for Patients With Severe Sepsis and Septic Shock: A Retrospective Cohort Study.

Objective:To test the hypothesis that interhospital transfer causes significant delays in the administration of appropriate antibiotics and compliance with the completion of Surviving Sepsis Bundle elements. Design:Single-center retrospective cohort study. Setting:A comprehensive 60,000-visit emergency department at a 711-bed Midwestern academic medical center. Patients:Patients with severe sepsis and septic shock treated between 2009 and 2014 were identified by International Classification of Diseases,9th Revision, Clinical Modification, codes, then divided into two cohorts: 1) transfer patients who arrived at the tertiary academic center after receiving care in a local community hospital and 2) control patients who presented directly to the tertiary academic center emergency department. Interventions:None. Measurement and Main Results:One hundred ninety-three patients were included. Transfer patients were more likely to require surgery in the hospital (p < 0.001) and require ICU care (p = 0.001) but had similar illness severity based on (Acute Physiology and Chronic Health Evaluation II, 17.7 vs 17.5; p = 0.662). Antibiotic administration at 1 and 3 hours was comparable between the two cohorts, but initial antibiotic appropriateness was lower in transfer patients (34% vs 79%; p < 0.001). Transfer patients were less likely to have fluid resuscitation started by 3 hours (54% vs 89%; p < 0.001), but they were not less likely to receive an adequate fluid bolus (30 mL/kg) by the time of hospital admission (p = 0.056). There were no differences in ICU length of stay or mortality. Conclusions:Interhospital transfer significantly delays administration of appropriate initial antibiotics and resuscitation therapy. Future studies are needed to identify strategies of providing regional sepsis care prior to transfer to tertiary centers and to continue care pathways during the interhospital transfer process.

Extending Acute Trials to Remote Populations: A Pilot Study During Interhospital Helicopter Transfer

Background and Purpose— Methods to increase recruitment into acute stroke trials are needed. The purposes of this study were to evaluate the safety and acceptability of initiating acute stroke trials during early helicopter evacuation and to test an intervention to facilitate informed consent. Methods— A randomized, controlled trial was done with patients with acute stroke who were transferred by helicopter to the University of Iowa Hospitals and Clinics from February 2007 to January 2008. The intervention to be evaluated was the use of fax and a telephone call to the patient/surrogate ahead of helicopter arrival at the outside emergency department. The aim was to improve the rate of subsequent consent (primary outcome) for a pilot trial of a potentially beneficial, low-risk medical intervention (ranitidine) to prevent aspiration pneumonitis. Consenting eligible patients received the infusion during the flight to University of Iowa Hospitals and Clinics. Results— One hundred patients were enrolled. Consent rate was 54% in the intervention group and 50% in the control group (P=0.69). However, the consent rate was higher (69%) when prearrival communications between the coinvestigator and potential subjects were successful (P=0.04). This approach resulted in an average gain of 59 minutes as compared with initiating recruitment on arrival to University of Iowa Hospitals and Clinics. Conclusions— Enrollment into stroke intervention trials is feasible during helicopter transportation from a community hospital emergency department to a tertiary stroke center. This underused resource may improve trial efficiency by enabling and expediting participation of remote populations currently excluded from research. Consent rates might be further improved by communication strategies that are more successful in reaching patients at outside emergency departments.

Feasibility of Acute Clinical Trials During Aerial Interhospital Transfer

Background and Purpose— In rural America, patients are often first seen at a small community hospital and then transferred to a tertiary care center by helicopter for further care. If acute clinical research were feasible during the aerial interhospital transport, more patients might be enrolled in trials at a critical earlier stage. Methods— Prospective data were collected for all aerial transfers of a university-based helicopter service from April 2005 to January 2006. Flight nurses were educated about stroke research and offered certification and participation. Data collected included patient characteristics and the availability of relatives to provide surrogate consent. Results— All 12 flight nurses completed the institutional review board certification requirements and collected data on 215 transfers. Sixty-one patients had acute stroke or myocardial events (MIs). The median time from symptom onset to helicopter arrival at an outside hospital was 213 minutes (range, 90 to 2135) for ischemic stroke (n=12), 186 (45 to 1332) for intracranial hemorrhage (n=28), and 157 (47 to 1044) for MI (n=21). A relative was available in >74% of those transfers. A trial with a 4-hour window would permit enrollment of 67% of the ischemic strokes, 82% of intracranial hemorrhage cases, and 76% of MI patients. Conclusions— Clinical trials are feasible during aerial interhospital transport of patients. Flight nurses became successful investigators in clinical research and were exposed to potentially eligible patients with the ability to consent either directly or through surrogates. This approach could improve current clinical trial recruitment in rural areas, as well as permit testing of inflight ancillary interventions to improve outcome during patient transport.

Inter-hospital transfer is associated with increased mortality and costs in severe sepsis and septic shock: An instrumental variables approach.

PURPOSE The objective of this study was to evaluate the impact of regionalization on sepsis survival, to describe the role of inter-hospital transfer in rural sepsis care, and to measure the cost of inter-hospital transfer in a predominantly rural state. MATERIALS AND METHODS Observational case-control study using statewide administrative claims data from 2005 to 2014 in a predominantly rural Midwestern state. Mortality and marginal costs were estimated with multivariable generalized estimating equations models and with instrumental variables models. RESULTS A total of 18 246 patients were included, of which 59% were transferred between hospitals. Transferred patients had higher mortality and longer hospital length-of-stay than non-transferred patients. Using a multivariable generalized estimating equations (GEE) model to adjust for potentially confounding factors, inter-hospital transfer was associated with increased mortality (aOR 1.7, 95% CI 1.5-1.9). Using an instrumental variables model, transfer was associated with a 9.2% increased risk of death. Transfer was associated with additional costs of

Prehospital oral chlorhexidine does not reduce the rate of ventilator-associated pneumonia among critically ill trauma patients: A prospective concurrent-control study

BACKGROUND Journal club is a standard component of residency education. Journal club focuses on review and interpretation of the medical literature with varying degrees of evidence-based medicine (EBM) education. OBJECTIVES To evaluate learning of EBM principles with an EBM curriculum implemented as a component of journal club. EBM competency was established using the Fresno test, a validated 12-question instrument of short-answer and essay-style questions to assess competency in EBM. METHODS An EBM curriculum was implemented that consisted of a focus on EBM topics (e.g., study validity, bias, confidence intervals, search strategies) using a structured journal club format using a peer instruction model. The Fresno test was used prior to and after the implementation of the first year of this curriculum to measure effectiveness of the intervention. A hierarchical multivariable model using generalized estimating equations was used to account for repeated measures in the primary outcome of change in total Fresno test score. RESULTS The total test scores did not increase significantly (105.4 vs. 120.9, p = 0.058) in the before-after analysis. The only subscore showing improvement was interpretation of study validity (32.1 vs. 40.4 points, p = 0.03). Attendance was significantly associated with Fresno test score, with those attending ≥ 6/11 sessions (55%) scoring 28.2 points higher (p = 0.003), and those attending fewer than six sessions scoring only 1.9 points higher (p = 0.81) than in the preintervention group. CONCLUSION An EBM curriculum implemented as part of journal club improves performance on the Fresno test among residents who attended at least six journal club sessions.

Characterizing demographics, injury severity, and intubation status for patients transported by air or ground ambulance to a rural burn center

PURPOSE The purposes of the study are to describe current practice of ventilation in a modern air medical system and to measure the association of ventilation strategy with subsequent ventilator care and acute respiratory distress syndrome (ARDS). MATERIALS AND METHODS Retrospective observational cohort study of intubated adult patients (n = 235) transported by a university-affiliated air medical transport service to a 711-bed tertiary academic center between July 2011 and May 2013. Low tidal volume ventilation was defined as tidal volumes less than or equal to 8 mL/kg predicted body weight. Multivariable regression was used to measure the association between prehospital tidal volume, hospital ventilation strategy, and ARDS. RESULTS Most patients (57%) were ventilated solely with bag valve ventilation during transport. Mean tidal volume of mechanically ventilated patients was 8.6 mL/kg predicted body weight (SD, 0.2 mL/kg). Low tidal volume ventilation was used in 13% of patients. Patients receiving low tidal volume ventilation during air medical transport were more likely to receive low tidal volume ventilation in the emergency department (P < .001) and intensive care unit (P = .015). Acute respiratory distress syndrome was not associated with prehospital tidal volume (P = .840). CONCLUSIONS Low tidal volume ventilation was rare during air medical transport. Air transport ventilation strategy influenced subsequent ventilation but was not associated with ARDS.
