Triage in mass-casualty events: the Haitian experience.

INTRODUCTION: Mass-casualty triage is implemented when available resources are insufficient to meet the needs of all patients in a disaster situation. The basic principle is to do the maximum good for the most casualties with the least amount of resources. There are limited data to support the applicability of this principle in massive disasters such as the January 2010 earthquake in Haiti, in which the number of patients seeking medical attention overwhelmed the local resources. OBJECTIVE: To analyze the application of a triage system developed for use in a mass-casualty setting with limited resources. The system was designed to admit only those patients who had medical conditions requiring urgent treatment that were within the capabilities of the hospital and had a good chance of survival after discharge. Priority was given to those whose treatment could be administered within a short hospital stay. METHOD: A retrospective, observational review of computerized registration forms of Haitian earthquake victims who sought medical care at a 72-bed field hospital within four to 14 days after the event. An analysis of the efficacy of the triage protocol that was used followed, using length of hospital stay to measure consumption of resources. RESULTS: A total of 1,111 patients were triaged for treatment in the field hospital within 14 days of the earthquake. The median length of stay for all patients for whom data was available was 16 hours (mean = 29.7 hours). The majority of patients (n = 620, 65%) were discharged within 24 hours. Two hundred five patients underwent surgery and were discharged within a median of 39 hours (mean = 52.6 hours); of these, 124 (62%) were discharged within 48 hours. The total mortality of the treated patients was 1.5% (n = 17). CONCLUSIONS: Currently accepted triage principles for the most part are appropriate for efficiently providing medical care in a disaster area with extremely limited resources, but require extensive adaptation to local conditions.

Is the influenza vaccination rate of elderly patients affected by raising the vaccination rate of the staff at their primary health care clinics?

BACKGROUND: Influenza vaccination of community-dwelling elderly is widely recommended. Observational studies have shown a strong association between physicians' personal vaccination status and their reported level of recommendation to patients and possibly their patients' actual vaccination. No published trials have examined whether increasing vaccination rates of primary care staff raises vaccination among their patients. Proof of a positive effect would support the notion that vaccinating health care workers benefits their patients. OBJECTIVES: To examine whether an intervention to increase staff vaccination also increases vaccination of their patients aged 65 and over. METHODS: A trial examining an intervention aiming to raise staff immunization rates was performed in primary care community clinics in the Jerusalem area. The study population comprised the staff of 13 randomly chosen intervention clinics during the season of 2007-2008, with another 14 clinics serving as controls. The intervention resulted in a staff vaccination rate of 52.8% compared to 26.5% in the control clinics (66.1% and 32.2% among physicians). No intervention was directed at the patients. Data on patient vaccination and other patient characteristics were extracted from the health funds' computerized databases. RESULTS: The percentage of patients vaccinated during the intervention season was 57.8% in both intervention and control groups, reflecting an increase of 14.4% compared to the previous season in the intervention clinics and of 13.4% in the control clinics. Logistic regression demonstrated a statistically significant association between intervention and patient vaccination with an odds ratio of 1.10 (95% confidence interval 1.03-1.18). However, analysis adjusting for clustering did not show a significant association. CONCLUSIONS: Increasing influenza vaccination of the medical staff did not substantially increase patient vaccination. These results do not show any patient benefit from staff vaccination in primary care.

Costs of appropriate and inappropriate use of antibiotics in the emergency department.

BACKGROUND: Appropriate antibiotic use is of both clinical and economic significance to any health system and should be given adequate attention. Prior to this study, no in-depth information was available on antibiotic use patterns in the emergency department of Hadassah Medical Center. OBJECTIVES: To describe the use and misuse of antibiotics and their associated costs in the emergency department of Hadassah Medical Center. METHODS: We analyzed the charts of 657 discharged patients and 45 admitted patients who received antibiotics in Hadassah's emergency department during a 6 week period (29 April - 11 June 2007). A prescription was considered appropriate or inappropriate if the choice of antibiotic, dose and duration by the prescribing physician after diagnosis was considered suitable or wrong by the infectious diseases consultant evaluating the prescriptions according to Kunin's criteria. RESULTS: The overall prescribing rate of antibiotics was 14.5% (702/4830) of which 42% were broad-spectrum antibiotics. The evaluated antibiotic prescriptions numbered 1105 (96 prescriptions containing 2 antibiotics, 2 prescriptions containing 3 antibiotics), and 54% of them were considered appropriate. The total inappropriate cost was 3583 NIS (1109 USD PPP) out of the total antibiotic costs of 27,300 NIS (8452 USD PPP). The annual total antibiotic cost was 237,510 NIS (73,532 USD PPP) and the annual total inappropriate cost was 31,172 NIS (9648 USD PPP). The mean costs of inappropriate prescriptions were highest for respiratory (112 NIS, 35 USD PPP) and urinary tract infection (93 NIS, 29 USD PPP). There were more cases when the optimal cost was lower than the actual cost (N = 171) than when optimal cost was higher than the actual cost (N = 9). In the first case, the total inappropriate costs were 3805 NIS (1178 USD PPP), and in the second case, -222 NIS (68.7 USD PPP). CONCLUSIONS: The use of antibiotics in emergency departments should be monitored, especially in severely ill patients who require broad-spectrum antibiotics and for antibiotics otherwise restricted in the hospital wards. Our findings indicate that 12% of the total antibiotic costs could have been avoided if all prescriptions were optimal.

Infection control in field hospitals after a natural disaster: lessons learned after the 2010 earthquake in Haiti.

After the January 12, 2010, earthquake in Haiti, Project Medishare and the University of Miami organized, built, and staffed a 200-bed field hospital (the University of Miami Hospital in Haiti [UMHH]) on the outskirts of Port-au-Prince. We describe the operational challenges of providing a safe environment at the UMHH. Furthermore, we compared how these issues were addressed at this ad hoc hospital with how they were addressed at the field hospital of the Israel Defense Force, a fully deployable hospital with an organization fine-tuned as a result of prior disaster situations, also in Haiti.
