Prevalence of Horizontal Violence Among Emergency Attending Physicians, Residents, and Physician Assistants.

INTRODUCTION: Horizontal violence (HV) is malicious behavior perpetrated by healthcare workers against each other. These include bullying, verbal or physical threats, purposeful disruptive behavior, and other malicious behaviors. This pilot study investigates the prevalence of HV among emergency department (ED) attending physicians, residents, and mid-level providers (MLPs). METHODS: We sent an electronic survey to emergency medicine attending physicians (n=67), residents (n=25), and MLPs (n=24) in three unique EDs within a single multi-hospital medical system. The survey consisted of 18 questions that asked participants to indicate with what frequency (never, once, a few times, monthly, weekly, or daily) they have witnessed or experienced a particular behavior in the previous 12 months. Seven additional questions aimed to elicit the impact of HV on the participant, the work environment, or the patient care. RESULTS: Of the 122 survey invitations 91 were completed, yielding a response rate of 74.6%. Of the respondents 64.8% were male and 35.2% were female. Attending physicians represented 41.8%, residents 37.4%, and MLPs 19.8% of respondents. Prevalence of reported behaviors ranged from 1.1% (Q18: physical assault) to 34.1% (Q4: been shouted at). Fourteen of these behaviors were most prevalent in the attending cohort, six were most prevalent in the MLP cohort, and three of the behaviors were most prevalent in the resident cohort. CONCLUSION: The HV behaviors investigated in this pilot study were similar to data previously published in nursing cohorts. Furthermore, nearly a quarter of participants (22.2%) indicated that HV has affected care for their patients, suggesting further studies are warranted to assess prevalence and the impact HV has on staff and patients.

Management of an extremely premature infant in the out-of-hospital environment.

The rate of premature infant mortality has decreased over the last several decades, with an accompanying decrease in the gestational age of premature infants who survive to hospital discharge. Emergency medical services (EMS) providers are sometimes called to provide prehospital care for infants born at the edge of viability. Such extremely premature infants (EPIs) present medical and ethical challenges. In this case report, we describe an infant born at 24 weeks into a toilet by a mother who thought she had miscarried. The EMS providers evaluated the infant as nonviable and placed him in a plastic bag for transport to a local emergency department (ED). The ED staff found the infant to have a bradycardic rhythm, initiated resuscitation, and admitted him to the neonatal intensive care unit. The infant died seven days later. We review the literature for recommendations in resuscitation of EPIs and discuss the ethics regarding their management in the prehospital setting.

Bispectral index monitoring in helicopter emergency medical services patients.

Background. Many critically ill patients are given sedatives and paralytics to facilitate aeromedical transport. Bispectral index (BIS) monitoring is a computer-derived electroencephalography (EEG) analog currently used to monitor the level of awareness of sedated patients. It gives a score of 1-100, with 1 representing no brain function and 100 representing a completely alert patient. Objective. To evaluate whether critically ill patients are adequately sedated during aeromedical transport. Methods. This was a prospective, observational study of a convenience sample of critically ill patients transported by helicopter. All intubated patients who received sedatives and/or paralytics to facilitate transport were eligible for enrollment by the attending clinician. Prior to liftoff, a BIS sensor was applied to the patient's forehead. Minimum, maximum, and mean BIS index scores were recorded every minute during transport. Results. Forty-seven patients (57% male) were enrolled, with a median age of 60 years (interquartile range [IQR] 18-81, range 14 to 86 years). The median duration of monitoring was 15.0- minutes (IQR 6.0-26.0, range 2 to 33). The median BIS score was 54.6 (IQR 38.6-67.3, range 28 to 89.5). Only two patients (4.3%, 95% confidence interval [CI] 0.5% to 14.8%) had at least one BIS score greater than 85, the accepted threshold for recall. Conclusion. These results suggest that patients are adequately sedated during air medical transport.

Do outcome measures for trauma triage agree?

OBJECTIVE: The goal of trauma triage is to match resources to the needs of seriously injured patients. The trauma triage literature has used a variety of outcome measures to assess appropriate trauma activation. The objective of this study was to determine the agreement between procedural and nonprocedural outcome measures in a population of seriously injured patients transported to a single trauma center. METHODS: Study authors reviewed all "level 2" trauma activations (January 2002-December 2003) at an American College of Surgeons (ACS) Level 1 trauma center. "Level 2" trauma activations were based on modified ACS Committee on Trauma (COT) triage criteria. Outcomes were classified as nonprocedural (Injury Severity Score [ISS] > 15 and intensive care unit [ICU] admission) and procedural (nonorthopedic emergent surgery, emergency chest tube placement, emergency department intubation, emergency department transfusion, or emergent interventional radiology care). RESULTS: Of 479 patients, five were transferred out of hospital. The remaining 474 were predominantly male (62%), with a mean age of 39.7 years. Their average ISS was 13.2. There were nine deaths. For all subjects, 144 (30%) were admitted to the ICU, 172 (36%) had an ISS > 15, 80 (17%) received an emergent procedure, and 46 (10%) went for emergent surgery. Kappas comparing agreement of ISS > 15 with emergent resuscitation and emergent surgery were 0.31 and 0.15, respectively. Kappas comparing ICU admission with emergent resuscitation and emergent surgery were 0.51 and 0.26, respectively. CONCLUSIONS: We identify moderate to poor agreement between nonprocedural and procedural outcomes of trauma triage in this population.

Serial Bispectral index scores in patients undergoing observation for sedative overdose in the emergency department.

STUDY OBJECTIVE: Many patients who overdose on sedatives experience a declining mental status and eventually require endotracheal intubation. The goal of this study was to determine if serial bedside Bispectral index (BIS) scores monitoring can be used to detect the eventual need for intubation in overdosed patients who are undergoing observation in the ED. METHODS: This was a prospective, observational study of a convenience sample of patients who presented to the Hennepin County Medical Center ED between June and November 2002. Patients being treated and observed for a suspected sedative ingestion were eligible. Upon presentation, a Bispectral electroencephalographic probe was applied to the patient's forehead, and a BIS score was recorded at 0 and 20 minutes. The Altered Mental Status scale was used to describe the patient's clinical status. Data were collected by trained research assistants. Data are described with descriptive statistics. The mean changes in BIS score between patients who did and did not require intubation are compared with t tests, and the outcome of patients with stable vs declining BIS scores were compared with chi(2) tests. RESULTS: Seventy-six patients were enrolled. The mean initial BIS score was 83.9 (95% CI, 79.7-88.1; range, 9-99). The mean change in BIS scores during the 20-minute observation period for the patients who required intubation was -13.5 (95% CI, -30.2 to 3.2) and was +6.7 (95% CI, 3.3-10.1) for those who were not intubated. Sixteen patients had an initial BIS score below 70. Of these patients, 6 were intubated. All intubations occurred during the 20 minutes, and this group had a mean initial BIS of 47.2 (95% CI, 35.6-58.8). The 10 patients with an initial BIS below 70 who were not intubated had a mean increase in BIS score of 23.3 (95% CI, 11.7-33.9) during the 20 minutes. Of the 60 patients whose first BIS score was above 70, 5 were eventually intubated during their ED treatment. The mean change in BIS was -36.4 (95% CI, -18.7 to -54.1) for the intubated patients vs +7.9 (95% CI, 4.4-11.3) for nonintubated patients during the first 20 minutes. CONCLUSION: The overdosed patients who required intubation during their ED treatment experienced a mean decrease in BIS during the first 20 minutes, compared with those who did not. Bispectral index scores monitoring may prove useful for earlier ED treatment and decision making regarding sedative overdose patients.

Discontinuation of droperidol for the control of acutely agitated out-of-hospital patients.

OBJECTIVE: To identify the effects of the removal of droperidol as a treatment option for sedation of agitated out-of-hospital patients. METHODS: This was a retrospective review conducted January 1, 2001, through December 5, 2002, of patients with an out-of-hospital diagnosis of agitation who received either droperidol or midazolam prior to arrival in the emergency department (ED). The need for continuous cardiac or pulse oximetry monitoring, intubation, critical care ED management, intensive care unit admission, and mortality was reviewed. RESULTS: Seventy-one patients received droperidol or midazolam for acute agitation in the out-of-hospital setting. Forty-one patients received droperidol in 2001 (D2001); three patients received midazolam in 2001 (M2001). No patients received droperidol in 2002, and 27 patients received midazolam (M2002). Comparing the D2001 and M2002 groups, the need for continuous pulse oximetry monitoring in the ED [14/41 (34.1%) versus 18/27 (66.7%)], intubations [4/41 (9.8%) versus 10/27 (37.0%)], critical emergency medical services transports [5/41 (12.2%) versus 11/27 (40.7%)], critical ED care cases [6/41 (14.6%) versus 11/27 (40.7%)], and intensive care unit admissions [6/13 (46.2%) versus 14/15 (93.3%)] were increased in the M2002 group. No difference was found in the frequencies of ED cardiac monitoring, hospital admission, complications, or death. CONCLUSIONS: Since the removal of droperidol as a treatment option for out-of-hospital agitated patients, the authors have observed an increased frequency of continuous pulse oximetry monitoring, intubation, ED critical care management, and intensive care unit admission in patients requiring chemical sedation for control of agitation in the out-of-hospital setting.
