For patients who suffer out-of-hospital cardiac arrest, the time from collapse to initial defibrillation is the single most important factor that affects survival to hospital discharge. The purpose of this study was to compare the survival rates of cardiac arrest victims within an institution that has a rapid defibrillation program with those of its own urban community, tiered EMS system.

A logistic regression analysis of a retrospective data series (n = 23) and comparative analysis to a second retrospective data series (n = 724) were gathered for the study period September 1994 to September 1999. The first data series included all persons at Casino Windsor who suffered a cardiac arrest. Data collected included: age, gender, death/survival (neurologically intact discharge), presenting rhythm (ventricular fibrillation (VF), ventricular tachycardia (VT), or other), time of collapse, time to arrival of security personnel, time to initiation of cardiopulmonary resuscitation (CPR) prior to defibrillation (when applicable), time to arrival of staff nurse, time to initial defibrillation, and time to return of spontaneous circulation (if any). Significantly, all arrests within this series were witnessed by the surveillance camera system, allowing time of collapse to be accurately determined rather than estimated. These data were compared to those of similar events, times, and intervals for all patients in the greater Windsor area who suffered cardiac arrest. This second series was based upon the Ontario Prehospital Advanced Life Support (OPALS) Study database, as coordinated by the Clinical Epidemiology Unit of the Ottawa Hospital, University of Ottawa.

The Casino Windsor had 23 cases of cardiac arrests. Of the cases, 13 (56.5%) were male and 10 (43.5%) were female. All cases (100%) were witnessed. The average of the ages was 61.1 years, of the time to initial defibrillation was 7.7 minutes, and of the time for EMS to reach the patient was 13.3 minutes. The presenting rhythm was VF/VT in 91% of the case. Fifteen patients were discharged alive from hospital for a 65% survival rate. The Greater Windsor Study area included 668 cases of out-of-hospital cardiac arrest: Of these, 410 (61.4%) were male and 258 (38.6%) were female, 365 (54.6%) were witnessed, and 303 (45.4%) were not witnessed. The initial rhythm was VF/VT was in 34.3%. Thirty-seven (5.5%) were discharged alive from the hospital.

This study provides further evidence that PAD Programs may enhance cardiac arrest survival rates and should be considered for any venue with large numbers of adults as well as areas with difficult medical access.

Although every hospital needs a security plan for the support of immobile patients who do not possess autonomous escape capabilities, little information exists to assist in the development of practical patient evacuation methods.

1) In hospitals during disasters, incident leadership of the fire authorities can be supported effectively by hospital executives experienced in the management of mass casualties; and 2) As an alternative for canvas carry sheets, rescue drag sheets can be employed for emergency, elevator-independent, patient evacuation.

A hospital evacuation exercise was planned and performed to obtain experiences in incident command and to permit calculation of elevator-independent patient transport times. Performance of incident leadership was observed by means of pre-defined checklists. The effectiveness and efficiency of carrying teams with five persons each were compared to those with a rescue drag sheet employed by a single person.

Incident command for hospitals during a disaster is enhanced considerably by pre-defined and trained executives who are placed at the immediate disposal of the fire authorities. For elevator-independent patient transport, the rescue drag sheet was superior to conventional carrying measures because of a reduced number of transport personnel required to move each patient. With this method, patient transport times averaged 54 m/min. flat and 18 seconds for one floor descent.

Experiences from a hospital during an evacuation exercise provided decision criteria for changes in the disaster preparedness plan. Hospital incident leadership was assigned to executives-in-charge in close co-operation with the fire authorities. All beds were equipped with a rescue drag sheet. Both concepts may help to cope with an emergency evacuation of a hospital.

An extensive review was conducted using the computerized databases Medline and Healthstar from 1977 through May 2002. Articles selected contained information pertaining to mass-gathering variables. These articles were read, abstracted, analyzed, and compiled.

Multiple variables are present during a mass gathering, and they interact in complex and dynamic ways. The interaction of these variables contributes to the number of patients treated at an event (medical usage rate) as well as the observed injury patterns. Important variables include weather, event type, event duration, age, crowd mood and density, attendance, and alcohol and drug use.

Developing an understanding of the variables associated with mass gatherings should be the first step for event planners. After these variables are considered, a thorough needs analysis can be performed and resource allocation can be based on objective data.

This study explores the value of Emergency Medical Services (EMS) experience for students applying to medical school. Methods: Surveys were sent to 67 medical schools in the eastern United States and Canada. Using a five-point Likert scale, the survey asked the respondent to rate the amount of consideration given to Emergency Medical Technician (EMT) or paramedic experience when making admissions decisions (1 = very little to 5 = strong), and to describe the influence of that experience (1 = very negative to 5 = very positive).

Usable responses were received from 21 schools. The median rating for the consideration given to EMS experience was “some consideration” for both EMT and paramedic experience, with 85.7% of respondents assigning that rating or higher. The median rating for the influence of that experience was “somewhat positive” for both EMT and paramedic experience. Only 14.3% of the returned surveys rated EMS experience as “neutral”, and no respondent reported EMS experience as a “negative”.

EMS experience receives at least some consideration during the admissions process at most of the responding institutions in the United States and Canada. Experiences at either the EMT or Paramedic level are viewed similarly. None of the responding institutions viewed EMS experience negatively.

To study the rate of prehospital mortality before establishment of a rescue system for victims of land-mines in Iran.

Survey at rural clinics in mine-affected areas, and retrospective review of public patient records.

A total of 36.4% of casualties from land-mines in the study area died during the period of 1989–1999. The mortality seems highest in those victims who were torso injured.

The mortality rate from accidents involving land-mines in the study area was high. Most fatalities seemingly occurred in the prehospital setting.

Very little evidence is available on the experience of ambulance-personnels or on the impact of prehospital interventions on total prehospital time.

On-scene-time increases with the number of prehospital techniques used, and ambulance-technicians achieve only limited clinical experience in prehospital techniques.

Prospective, observational registry study including 56 ambulance technicians from two ambulance stations in the mixed urban/rural county and 5,557 patients who were brought to a hospital in 1998. The number of cases in which each ambulance-technician performed various kinds of prehospital techniques, and the average on-scene time for each prehospital technique and several combinations of prehospital techniques were calculated.

There were large differences between the number of times each technique was used. On-scene time was smallest when no techniques were used and tended to increase with the number of interventions used. On-scene-time was relatively low for patients with cardiac arrest.

The Danish ambulance-technicians' curriculum includes interventions for which the technicians only achieve limited practical experience. Prehospital interventions are associated with an increase of on-scene time.
