vTrain: a novel curriculum for patient surge training in a multi-user virtual environment (MUVE).

INTRODUCTION: During a pandemic influenza, emergency departments will be overwhelmed with a large influx of patients seeking care. Although all hospitals should have a written plan for dealing with this surge of health care utilization, most hospitals struggle with ways to educate the staff and practice for potentially catastrophic events. Hypothesis/Problem To better prepare hospital staff for a patient surge, a novel educational curriculum was developed utilizing an emergency department for a patient surge functional drill. METHODS: A multidisciplinary team of medical educators, evaluators, emergency preparedness experts, and technology specialists developed a curriculum to: (1) train novice users to function in their job class in a multi-user virtual environment (MUVE); (2) obtain appropriate pre-drill disaster preparedness training; (3) perform functional team exercises in a MUVE; and (4) reflect on their performance after the drill. RESULTS: A total of 14 students participated in one of two iterations of the pilot training program; seven nurses completed the emergency department triage course, and seven hospital administrators completed the Command Post (CP) course. All participants reported positive experiences in written course evaluations and structured verbal debriefings, and self-reported increase in disaster preparedness knowledge. Students also reported improved team communication, planning, team decision making, and the ability to visualize and reflect on their performance. CONCLUSION: Data from this pilot program suggest that the immersive, virtual teaching method is well suited to team-based, reflective practice and learning of disaster management skills.

CrowdED: crowding metrics and data visualization in the emergency department.

OBJECTIVES: Emergency department (ED) crowding metrics were validated in our facility and a new technique of data visualization is proposed. DESIGN: A sequential cross-sectional study was conducted in our ED during October 2007. Data were collected every 2 hours by a research assistant and included patient arrivals and acuity levels, available inpatient and ED beds, ambulance diversion status, staff present, and patient reneging. The charge nurse and an attending physician also completed a single-question crowding instrument. Pearson correlation coefficients were calculated and logistic regression were performed to test the usefulness of the crowding score and test significance of the data visualization trends. SETTING/PARTICIPANTS: Our ED is an adult, level-III, veterans administration ED in urban southern California. It is open 24 hours per day, has 15 treatment beds with 4 cardiac monitors, and typically sees about 30 000 patients per year. MAIN OUTCOME MEASURE(S): The key outcome variables were patient reneging (number of patients who left before being seen by a physician) and ambulance diversion status. RESULTS: Average response rate was 72% (n = 227) of sampling times. Emergency Department Work Index, demand value, lack of inpatient beds, census, patients seen in alternate locations, and patient reneging correlated significantly (P < .01) with the crowding instrument. Staff workload ranks predicted patient reneging (odds ratio 6.0, 95% confidence interval 2.3-15.4). The data visualization focused on common ED overcrowding metrics and was supported by logistic regression modeling. CONCLUSIONS: The demand value, ED Work Index, and patient reneging are valid measures of crowding in the studied ED, with staff workload rank being an easy, 1-question response. Data visualization may provide the site-specific crowding component analysis needed to guide quality improvement projects to reduce ED crowding and its impact on patient outcome measures.

Vaccinations in pneumonia (VIP): pneumococcal and influenza vaccination patterns among patients hospitalized for pneumonia.

BACKGROUND: Although the CDC ACIP (Advisory Committee on Immunization Practices) recommends that appropriate inpatients receive pneumococcal and influenza vaccines, adult vaccination rates for these remain low. We therefore examined perihospitalization vaccination rates for high-risk pneumonia inpatients. METHODS: A retrospective chart review of all pneumonia patients admitted to one community hospital from 6/1/95 to 5/31/96. Vaccination history, co-morbidity, mortality, and prior and subsequent pneumonia admissions were recorded. Primary care providers and nursing homes were contacted to complete and verify vaccine histories. RESULTS: For 173 total admissions (160 subjects), vaccine histories were documented in the hospital chart in less than 0.5% of patients. While 97% had indications for both vaccines at the time of admission, no vaccines were given in the hospital and less than 5% had documented vaccinations during the subsequent 3 years. CONCLUSIONS: Despite clear indications, few patients had documented vaccination at any time. These data lend urgency to the recommendation that pneumococcal and influenza vaccines should be routinely administered to pneumonia inpatients at discharge. Furthermore, they illustrate the need for an improved method for tracking individual adult vaccinations.

Smoking cessation for high school students. Impact evaluation of a novel program.

This pilot study was designed to evaluate the feasibility and the impact of a smoking-cessation program that would meet the specific needs of high school students. Feedback from focus groups conducted with adolescent smokers at a Connecticut high school was used to develop a tailored intervention. Intervention components included commonly used behavioral strategies, with additional options to assist students to quit smoking, including use of bupropion, concomitant support for parent smoking cessation, stress management, and physician counseling. On completion, 20 of the 22 enrolled students remained committed to quitting. Twenty-seven percent of students quit smoking and 69% of those who continued to smoke reduced the number of cigarettes smoked per day by an average of 13. Providing additional options to students and additional support for concomitant parental cessation may enhance the appeal of adolescent smoking-cessation programs. Further investigation into efficacy of bupropion use for adolescent cessation is warranted.

Utility of HbA(1c) levels for diabetes case finding in hospitalized patients with hyperglycemia.

OBJECTIVE: We evaluated the role of a single measurement of HbA(1c) in a diabetes case finding in hospitalized patients with random hyperglycemia at admission. RESEARCH DESIGN AND METHODS: From 20 March to 31 July 2000, 508 patients admitted through the emergency department of one hospital were tested for random hyperglycemia (plasma glucose [PG] >125 mg/dl). Consenting patients with hyperglycemia (without preexisting diabetes or on corticosteroids) underwent testing for HbA(1c) levels, two fasting PG levels, and an outpatient oral glucose tolerance test (OGTT) if necessary. RESULTS: Of the patients, 50 (9.8%) met the inclusion criteria. Of these, 70% (n = 35) completed the study, and 60% (n = 21) were diagnosed with diabetes. Patients with diabetes had higher HbA(1c) levels than subjects without diabetes (6.8 +/- 0.4 vs. 5.3 +/- 0.1%, P = 0.002). An HbA(1c) level >6.0% was 100% specific (14/14) and 57% sensitive (12/21) for the diagnosis of diabetes. When a lower cutoff value of HbA(1c) at 5.2% was used, specificity was 50% (10/21) and sensitivity was 100% (7/14). CONCLUSIONS: In acutely ill patients with random hyperglycemia at hospital admission, an HbA(1c) >6.0% reliably diagnoses diabetes, and an HbA(1c) level <5.2% reliably excludes it (paralleling the operating characteristics of the standard fasting glucose measurements); however, the rapidity of the HbA(1c) level can be useful for diabetes case finding and treatment initiation early in the hospital course.
