Duration of patient immobilization in the ED

In this article we seek to determine the duration of immobilization in patients presenting to the emergency department (ED). We conducted a 10-week prospective study of a convenience sample of patients transported to a level one trauma center immobilized with a backboard and cervical collar. Total backboard time (TBT) was measured from the time the ambulance left the scene to the time the patient was removed from the backboard, while total ED backboard time (TEDBT) was measured from the time of arrival at the ED to the time of backboard removal. There were 138 patients entered in the study. Insufficient data excluded 36 patients from further analysis. TBT was available for 92 patients and averaged 63.63 (+/-45.87) minutes. Dividing patients into those who were removed from the backboard prior to radiographs (n = 85), the TBT average was 53.9 minutes (+/-30.1), whereas the average for those who had radiographs prior to removal from the backboard (n = 7) was 181.3 minutes (+/-41.6). There were 102 patients for whom TEDBT was available and averaged 46.36 (+/-44.88) minutes. Dividing patients into those who were removed from the backboard prior to radiographs (n = 95), the TEDBT average was 37.6 minutes (+/-29.6), whereas the average for those who had radiographs prior to removal from the backboard (n = 7) was 165.3 minutes (+/-49.7). Patients are left on backboards for significant periods of time even when no radiographs are taken prior to backboard removal.     

Analgesia delivery in the ED

OBJECTIVE: The aim of this study was to evaluate the effectiveness of analgesia delivery, in the emergency department setting, to patients presenting with acute pain, with regard to guidelines from the British Association of Accident and Emergency Medicine (BAEM). METHODS: A retrospective analysis of patient records. We measured the time intervals between patient arrival, assessment, and the delivery of analgesia. Clinical outcomes were compared with national target guidelines. RESULTS: The mean interval for patients with moderate pain was 3 hours and 46 minutes, and for those with severe pain, 1 hour and 12 minutes. The range was from 8 minutes to 4 hours and 11 minutes. The number of patients not receiving analgesia within BAEM best practice guidelines was 68%. CONCLUSION: There is a significant delay in patients with acute pain receiving any form of analgesia. Performance in relation to BAEM guidelines is poor. Several areas have been identified to make practical changes to service provision and patient care.     

Effects of implementing a rapid admission policy in the ED

Objective

The purpose of this study is to determine the impact of a new rapid admission policy (RAP) on emergency department (ED) length of stay (EDLOS) and time spent on ambulance diversion (AD).

Methods

The RAP, instituted in January 2005, allows attending emergency physicians to send stable patients, requiring admission to the general medicine service, directly to available inpatient beds. The RAP thereby eliminates 2 conventional preadmission practices: having admitting physicians evaluate the patient in the ED and requiring all diagnostic testing to be complete before admission. We compared patient characteristics, percentage of patients leaving without being seen, EDLOS for admitted patients, time on AD, and total adjusted facility charge for a 3-month period after the RAP implementation to the same period of the prior year.

Results

There was a 1.1% increase in census with no difference in patient demographics, acuity, or disposition categories for the 2 periods. The EDLOS decreased on average by 10.1 minutes (95% confidence interval [CI], 3.3-17.0 minutes), resulting in an average of 4.2 hours of extra bed availability per day. Weekly minutes of AD decreased 169 minutes (95% CI, 29-310 minutes). There was also a 3.2% increase (95% CI, 3.1%-3.3%) in adjusted facility charge between these periods in 2005 compared with 2004.

Conclusions

The RAP resulted in a small decrease in the EDLOS, which likely decreased AD time. The resulting small increase in ED volume and higher acuity ambulance patients significantly improved ED revenue. Wider implementation of the policy and more uniform use among emergency physicians may further improve these measures.     

Impact of trauma activation on the ED length of stay for nontraumatic patients

Introduction

Trauma activation prioritizes hospital resources for the assessment and treatment of trauma patient over all patients in the emergency department (ED). We hypothesized that length of stay (LOS) is longer for nontrauma patients during a trauma activation.

Methods

A retrospective, case-control chart review was conducted in a level I trauma center. Cases consist of patients who present 1 hour before and after the presentation of the trauma activation. Controls were patients presenting to the ED during the same period exactly 1 week before and after the cases. Confounding variables measured included sex, age, arrivals, and census for the 3 areas.

Results

Two hundred ninety-four trauma events occurred from January 1 until September 30, 2009. A significant difference was found between LOS of patients seen during a trauma activation with an average increase of 10.7 minutes in LOS (P =.0082; 95% confidence interval [CI], 2.8-18.7). This difference is attributable to the middle acuity area of the ED, in which the average increase in LOS was 20.3 minutes (P = .0004; 95% CI, 9.1-31.5). Significant LOS difference was not found when a trauma activation had an LOS of less than 60 minutes (P = .30; 95% CI, −7.1-61.7 for trauma LOS <60 minutes vs P = .02; 95% CI, 1.6-18.0 for trauma LOS ≥60 minutes).

Conclusion

This retrospective case-control chart review identified an increase in ED LOS for patient presenting during trauma activations. Resource prioritization should be accounted for during times when these critical patients enter the ED.     

Productivity indicators in a sterilization central supply

This study identifies productivity indicators at a Sterilization Central Supply (CME) through documents, observation and time counting of the process for two items selected from the sample: a bandage pack and a herniorrhaphy box. The monthly average production was 30,466.42 items, and the production capacity per hour was 10.3 items per employee. The bandage pack averaged 295 minutes from the expurgation area to storage; the manual process lasted 46 minutes and the automated 88 minutes. For the herniorrhaphy box the average was 329 minutes; the manual process lasted 60 minutes and automated 98 minutes. In the bandage kit, the manual process used up 59.23% of the productivity hours in the expurgation area, 3.28% in the preparation, 10.94% in the sterilization process, and 26.31% in storage and distribution. Figures for the manual process of herniorrhaphy box were: expurgation, 11.84%; preparation, 16.20%; storage and distribution, 7.47%; and sterilization, 1.89%. The study made possible to assess the results and to analyze the working process at the CME.     

Factors associated with longer ED lengths of stay

Objective

The aim of the study was to identify and quantify patient, physician, hospital, and system factors that are associated with a longer ED length of stay.

Methods

Data were from the 2001-2003 National Hospital Ambulatory Medical Care Survey. The primary outcome was length of stay in minutes. Predictor variables were patient level (eg, age, triage score), physician level (eg, level of training), and hospital/system level (eg, geographic location, ownership).

Results

Admitted patients' median length of stay was 255 minutes (interquartile range, 160-400); discharged patients stayed a median of 120 minutes (interquartile range, 70-199). Factors independently associated with longer ED stays for admitted patients were Hispanic ethnicity (+20 minutes), computed tomography scan or magnetic resonance imaging (+36 minutes), and hospital location in a metropolitan area (+32 minutes). Intensive care unit admissions had a shorter length of stay (−30 minutes).

Conclusion

Several factors are associated with significant increases in ED length of stay and may be important factors in strategies to reduce length of stay.     

The feasibility of full computerization in the ED

For understanding the feasibility of full computerization of an emergency department (ED), we investigated the completion rate performed by doctors, nurses, or registration clerks since the implementation of full computerization in our ED. We evaluated the changing style of chart-recording, from hand-writing pattern to full computer recording, by recording the execution rate of different information keyed by doctors, nurses, or registration clerks according to their work in ED. We recorded and analyzed different monthly reports of the execution rate in the 18-month period of study. Statistical analysis was performed using Wilcoxon rank-sum test or Kruskal-Wallis one-way ANOVA. The average monthly census was 4570.1 +/- 580.7 (95% confidence interval [CI] for mean: 4281.3, 4858.9). The average execution rate for mode of arrival and triage classification were 97.1 +/- 4.1% (95% CI for mean: 95.1%, 99.1%) and 97.2 +/- 4.1% (95% CI for mean: 95.2%, 99.2%), respectively. In comparison with the execution rate for disposition status between the period of the first 10 months (keying data by nurses) and the late 8 months (keying data by clerks), it showed 72.0 +/- 33.2% v 96.7 +/- 2.0%; 66.7 +/- 35.0% v 95.8 +/- 1.9%; 57.5 +/- 32.0% v 88.2 +/- 8.2% in nontrauma, trauma and pediatric section, respectively, with statistic significance (P <.01). To compare the rate of execution performed by physicians, we divided the study period into 3 phases (phase 1: first 6 months, phase 2: 7-12 months, phase 3: 13-18 months of the study period). The results were statistically significant (P =.004) in phase 3 (83.4 +/- 5.3%) with higher execution rate than phase 1 (69.7 +/- 7.7%) and phase 2 (75.2 +/- 4.9%) in trauma physician. In the pediatric section, it was also significantly higher in phase 3 than phase 2 (88.2 +/- 7.7% v 70.7 +/- 5.9%, P =.012). We concluded that it is efficient to key in data by registration clerks instead of nurses, and it takes time to persuade and educate most physicians to cooperate in using the computer while seeing patients.

Capillary lactic acid validation in an ED

Introduction

One of the most used methods to evaluate patients with a high risk not responding to clinical treatment is the measurement of blood levels of lactic acid (LA). The objective of this study was to compare the sensitivity and specificity of an LA test for capillary and venous blood with LA test for arterial blood in a population of patients with tissue hypoperfusion and to evaluate the time needed for each test.

Materials and Methods

The following factors were evaluated: the performance of venous and capillary LA in relation to arterial LA, and the time needed to elicit each method from patient admission to mortality according to initial LA.

Results

Seventy-nine patients with a median age of 58 years were admitted. The area under the curve for capillary LA was 82% (95% confidence interval [CI], 73-91). The best cutoff point was 2.35, with a sensitivity of 81% (95% CI, 65-90) and a specificity of 70% (95% CI, 53-83). The average time from patient admission until arterial, venous, and capillary LA values were obtained was 112, 117, and 77 minutes, respectively. The patients who died within 3, 30, and 60 days showed an average arterial LA of 5.9, 1.9, and 2.2, respectively.

Conclusion

The utilization of capillary and venous LA is an effective method of evaluation and risk stratification for patients with different degrees of tissue hypoperfusion. The time needed to elicit capillary LA proved much faster with respect to arterial and venous LA.     

Patterns of analgesic use in trauma patients in the ED

The objective was to describe patterns of analgesic use for trauma patients treated in our emergency department (ED). We reviewed analgesic use in consecutive patients meeting American College of Surgeons (ACS) Trauma Center Guidelines. A comprehensive database was abstracted from this institution's Trauma Registry and medical records of each patient. A total of 38% (95% CI: 31-46%) of patients received analgesics. Time to administration of first dose of analgesia was 109 minutes (95% CI: 85-133). Women, patients with long bone and pelvic fractures, and those with a longer ED stay were most likely to receive analgesics. Patients with head trauma and those admitted to the intensive care unit were least likely to receive analgesics. Morphine was the most frequent analgesic used with an average total dose of 14 milligrams. A majority of patients meeting ACS Trauma Center Guidelines did not receive analgesics in the ED.     

Provision for clinic patients in the ED produces more nonemergency visits

This study sought to evaluate how the addition of a general practitioner (GP) surgery influences the utilization of an emergency department (ED). An intervention trial with historical control was conducted in a Swedish university hospital ED. A GP surgery was established in the ED by the addition of GP physicians without the addition of other personnel (nurses, secretaries, aids). The number of persons evaluated and managed by the GP physicians and ED physicians were quantified preintervention (April 1992 to October 1993) and postintervention (April 1994 to October 1995). Further information was obtained by questionnaires distributed to all physicians and patients during three sample study weeks: 1 week before intervention and 6 and 18 months after the intervention. Patient volume, percentages of inappropriate visits, and types of services were recorded. The addition of GP physicians increased the number of visits to the ED by 27% (4,694 per month to 5,952 per month). The percentage of patients managed in the ED who had nonurgent complaints (primary health care needs) increased with the intervention from 22% (95% confidence interval [CI] 19%, 25%) to 33% (95% CI 30%, 37%). The increased demand on the ED of patients with nonurgent complaints increased the average waiting time for patients with urgent or emergent complaints from 35 minutes to 40 minutes (14%). The introduction of GPs to an ED increased the number and proportion of patients presenting to the ED with nonurgent complaints.     

Determinants of timely management of acute bacterial meningitis in the ED

Purpose

The purpose was to study the emergency management of patients with suspected meningitis to identify potential areas for improvement.

Methods

All patients who underwent cerebrospinal fluid puncture at the emergency department of the University Hospital of Bern from January 31, 2004, to October 30, 2008, were included. A total of 396 patients were included in the study. For each patient, we analyzed the sequence and timing for the following management steps: first contact with medical staff, administration of the first antibiotic dose, lumbar puncture (LP), head imaging, and blood cultures. The results were analyzed in relation to clinical characteristics and the referral diagnosis on admission.

Results

Of the 396 patient analyzed, 15 (3.7%) had a discharge diagnosis of bacterial meningitis, 119 (30%) had nonbacterial meningitis, and 262 (66.3%) had no evidence of meningitis. Suspicion of meningitis led to earlier antibiotic therapy than suspicion of an acute cerebral event or nonacute cerebral event (P < .0001). In patients with bacterial meningitis, the average time to antibiotics was 136 minutes, with a range of 0 to 340 minutes. Most patients (60.1%) had brain imaging studies performed before LP. On the other hand, half of the patients with a referral diagnosis of meningitis (50%) received antibiotics before performance of an LP.

Conclusions

Few patients with suspected meningitis received antimicrobial therapy within the first 30 minutes after arrival, but most patients with pneumococcal meningitis and typical symptoms were treated early; patients with bacterial meningitis who received treatment late had complex medical histories or atypical presentations.     

Propofol by infusion protocol for ED procedural sedation

INTRODUCTION: Propofol is an effective agent for use in procedural sedation and analgesia (PSA). Most ED studies have used a bolus-dosed protocol. We evaluated the efficacy, complication rate, and satisfaction among caregivers and patients while using an infusion-dosed protocol of propofol for PSA in our ED. METHODS: A prospective, observational study was performed in our academic ED. Propofol use was at the discretion of the ordering physician and dosed by predetermined infusion protocol. Variables measured included adverse events, times of sedation, procedure, and recovery. Patient and provider satisfaction were measured using a 10-cm visual analog scale. RESULTS: Fifty patients were enrolled over 18 months. Procedures were varied, and all were successfully completed. The mean propofol dose was 174 mg (SD = 164 mg). Average times to sedation (4.6 minutes, SD = 2.6 minutes) and recovery (8.2 minutes, SD = 5.8 minutes) were short. Complications included 8 patients with respiratory depression and 6 with hypotension, all easily reversible. Satisfaction scores were uniformly high. Only 34% of patients had any memory of the procedure, and 94% would agree to use it again if necessary. CONCLUSIONS: Infusion-dosed propofol is effective for ED PSA. Total doses, effectiveness, satisfaction rates, and complications of infusion-dosed propofol are comparable to findings from studies using bolus-dosed protocols.

Critical care of medical and surgical patients in the ED: Length of stay and initiation of intensive care procedures

Little is known about the extent of critical care delivered to patients in the emergency department (ED) and its impact on ED lengths of stay or patient outcomes. The purpose of this study was to characterize the timing of care for critically ill patients, both medical and surgical, in the ED. The design was a retrospective review. The setting was a university teaching hospital. The subjects were ED patients subsequently admitted to a medical or surgical intensive care unit (ICU). The average length of stay in the ED was 367 minutes. Thirty percent of patients were boarded in the ED because of lack of beds in the ICU. Stabilization procedures were performed on 45 (27%) patients, on average 102 minutes after ED admission. Monitoring procedures were performed on 35 (21%), on average 170 minutes after ED admission. There were no significant differences in length of stay, use, and timing of critical procedures in medical and surgical patients. Critically ill patients represent a significant portion of ED patients and may remain in the ED for prolonged periods of time. One of the major contributors to these prolonged stays are lack of beds. Both resuscitative and monitoring procedures are often performed in the ED setting for all types of critical patients. The timing of these procedures indicates that they are performed when necessary for patient care regardless of ED or ICU setting. Thus, ICU care is often initiated and maintained in the ED setting. EDs must be staffed adequately with appropriately trained personnel to care for these patients.     

Efficacy and feasibility of acupuncture for patients in the ED with acute,nonpenetrating musculoskeletal injury of the extremities

Objectives

We conducted a pilot study to assess the efficacy of acupuncture as an analgesic intervention for patients presenting to the emergency department (ED) after minor acute trauma to the extremities. In addition, we sought to assess the feasibility of performing acupuncture in this setting.

Methods

Acupuncture was used as primary analgesia for a convenience sample of ED patients with acute, nonpenetrating extremity injury. Efficacy was measured using a visual analog scale before treatment, immediately after acupuncture (time 0), and every 30 minutes thereafter. A telephone call was made to patients within 72 hours to ascertain pain levels using a 0 to 10 numerical rating scale. Markers of feasibility included average time patients spent in the fast track area of the ED vs average time in the department (TID) for all fast track patients with similar injury.

Results

Of 47 patients approached, 20 (43%) consented to participate. The mean age of those who consented was 33 years, and 70% (n = 14) were male. Median change in visual analog scale score for preacupuncture vs time 0 was 16 mm, with range of 0 to 60 mm. Median numerical rating scale score at time of discharge and at follow-up was 3. Median TID was 135 minutes, with a range of 55 to 255 minutes. Patients with extremity injury who did not receive acupuncture had a median TID of 90 minutes.

Conclusions

This study suggests that acupuncture can be an effective analgesic intervention for patients with acute injury to the extremities. Acupuncture did not increase patients' TID. Minor complications were reported.     

Climatic and diurnal variation in suicide attempts in the ED

The aim of this study was to determine whether there is a relationship between climatic factors and suicidal behavior. A total of 1,119 suicide attempts were collected from hospital records between 1996 and 2001. A clear seasonal variation was seen in suicide attempts in the 15-24, 25-34, and over 65 age groups in men and in the 15-24, 25-34, and 35-44 age groups in women with peaks in the spring and summer. Suicide attempts were more frequent between the hours of 6:00-9:00 pm in males and 3:00-6:00 pm in females. People attempting suicide who have depression, anxiety, or a psychotic disorder usually attempt suicide in the summer. Whereas the monthly averages of humidity, ambient temperature, duration and intensity of sunlight were positively correlated with the number of monthly suicide attempts, cloudiness and atmospheric pressure were negatively correlated. In conclusion, we must keep in mind that suicides and suicide attempts are not only the effect of climatic changes and that the most important component is the individual's ability to deal with conflicts.

Blunt trauma in the obstetric patient: monitoring practices in the ED

This study was undertaken to determine the usually used approach to fetal monitoring in the emergency department (ED) of the less severely injured obstetric patient who has sustained blunt trauma. A written survey was sent to clinical directors of teaching programs in emergency medicine (EM) with inquiries on the usual way of monitoring, what studies were performed, and the usual disposition of the less-injured obstetric patient. From the 112 teaching programs surveyed in early 1996, there were 87 responses (78%). Seventy-eight percent of programs generally have fetal monitoring performed for 2 to 4 hours in obstetric trauma patients when the trauma is more than minor extremity injury. In 68%, fetal monitoring was not performed in the ED from the time of the initial assessment of fetal heart tones until the mother went to an obstetric area even though the average estimated time to radiographically clear a cervical spine was 36 minutes. In 92% of programs residents are taught cardiotocographic changes indicative of fetal distress but only 15% have such monitoring equipment in their department. However, 51% do have sonographic equipment in their department. Given a patient with a viable fetus who has no abdominal pain, 46% routinely use fetal monitoring if the mechanism is a simple fall whereas 92% use monitoring only if the mechanism is a rollover motor vehicle collision or a strike to the abdomen. It is generally recognized that fetal distress may occur subtly without overt clinical signs and that obstetric area monitoring for a period of several hours should take place. However, most teaching programs do not institute continuous fetal monitoring during the first 30 to 60 minutes that the mother is undergoing her work-up even though residents are taught such monitoring.
