Ambulance officers' use of online clinical evidence.
(73/217)
BACKGROUND: Hospital-based clinicians have been shown to use and attain benefits from online evidence systems. To our knowledge there have been no studies investigating whether and how ambulance officers use online evidence systems if provided. We surveyed ambulance officers to examine their knowledge and use of the Clinical Information Access Program (CIAP), an online evidence system providing 24-hour access to information to support evidence-based practice. METHODS: A questionnaire was completed by 278 ambulance officers in New South Wales, Australia. Comparisons were made between those who used CIAP and officers who had heard of, but not used CIAP. RESULTS: Half the sample (48.6%) knew of, and 28.8% had used CIAP. Users were more likely to have heard of CIAP from a CIAP representative/presentation, non-users from written information. Compared to ambulance officers who had heard of but had not used CIAP, users were more likely to report better computer skills and that their supervisors regarded use of CIAP as a legitimate part of ambulance officers' clinical role. The main reasons for non-use were lack of access(49.0%) and training(31.4%). Of users, 51.3% rated their skills at finding information as good/very good, 67.5% found the information sought all/most of the time, 87.3% believed CIAP had the potential to improve patient care and 28.2% had directly experienced this. Most access to CIAP occurred at home. The databases frequently accessed were MIMS (A medicines information database) (73.8%) and MEDLINE(67.5%). The major journals accessed were Journal of Emergency Nursing(37.5%), American Journal of Medicine(30.0%) and JAMA(27.5%). CONCLUSION: Over half of ambulance officers had not heard of CIAP. The proportion who knew about and used CIAP was also low. Reasons for this appear to be a work culture not convinced of CIAP's relevance to pre-hospital patient care and lack of access to CIAP at work. Ambulance officers who used CIAP accessed it primarily from home and valued it highly. Lack of access to CIAP at central work locations deprives ambulance officers of many of the benefits of an online evidence system. (+info)
Validation of a rule for termination of resuscitation in out-of-hospital cardiac arrest.
(74/217)
BACKGROUND: We prospectively evaluated a clinical prediction rule to be used by emergency medical technicians (EMTs) trained in the use of an automated external defibrillator for the termination of basic life support resuscitative efforts during out-of-hospital cardiac arrest. The rule recommends termination when there is no return of spontaneous circulation, no shocks are administered, and the arrest is not witnessed by emergency medical-services personnel. Otherwise, the rule recommends transportation to the hospital, in accordance with routine practice. METHODS: The study included 24 emergency medical systems in Ontario, Canada. All patients 18 years of age or older who had an arrest of presumed cardiac cause and who were treated by EMTs trained in the use of an automated external defibrillator were included. The patients were treated according to standard guidelines. Characteristics of diagnostic tests for the prediction rule were calculated. These characteristics include sensitivity, specificity, and positive and negative predictive values. RESULTS: Follow-up data were obtained for all 1240 patients. Of 776 patients with cardiac arrest for whom the rule recommended termination, 4 survived (0.5 percent). The rule had a specificity of 90.2 percent for recommending transport of survivors to the emergency department and had a positive predictive value for death of 99.5 percent when termination was recommended. Implementation of this rule would result in a decrease in the rate of transportation from 100 percent of patients to 37.4 percent. The addition of other criteria (a response interval greater than eight minutes or a cardiac arrest not witnessed by a bystander) would further improve both the specificity and positive predictive value of the rule but would result in the transportation of a larger proportion of patients. CONCLUSIONS: The use of a clinical prediction rule for the termination of resuscitation may help clinicians decide whether to terminate basic life support resuscitative efforts in patients having an out-of-hospital cardiac arrest.

Patients' experiences of care provided by emergency care practitioners and traditional ambulance practitioners: a survey from the London Ambulance Service.
(75/217)
Patients' experiences after receiving care from emergency care practitioners (ECPs) were compared with those after receiving care from traditional ambulance practitioners using a postal questionnaire distributed to 1658 patients in London; 888 responses were received. The responses of patients receiving care from both groups were similar and largely positive. But in two areas ("thoroughness of assessment" and "explaining what would happen next"), the care provided by ECPs was experienced as considerably better. These differences were partly explained by considerably fewer patients from ECPs being conveyed to the emergency department, suggesting that empowering ECPs to explore and explain alternatives to the emergency department improves patient satisfaction.

A brief overview of personal safety at incident sites.
(76/217)
Safety at the scenes of trauma is not routinely taught to ambulance crews or medical teams. This article considers identification of the various hazards at an assortment of scenes by looking for unstable energy sources. While no substitute for practical training and experience, it provides a concept around which safety awareness can be developed. (+info)
Increasing use of cardiopulmonary resuscitation during out-of-hospital ventricular fibrillation arrest: survival implications of guideline changes.
(77/217)
BACKGROUND: The most recent resuscitation guidelines have sought to improve the interface between defibrillation and cardiopulmonary resuscitation; the survival impact of these changes is unknown, however. A year before issuance of the most recent guidelines, we implemented protocol changes that provided a single shock without rhythm reanalysis, stacked shocks, or postdefibrillation pulse check, and extended the period of cardiopulmonary resuscitation from 1 to 2 minutes. We hypothesized that survival would be better with the new protocol. METHODS AND RESULTS: The present study took place in a community with a 2-tiered emergency medical services response and an established system of cardiac arrest surveillance, training, and review. The investigation was a cohort study of persons who had bystander-witnessed out-of-hospital ventricular fibrillation arrest because of heart disease, comparing a prospectively defined intervention group (January 1, 2005, to January 31, 2006) with a historical control group that was treated according to previous guidelines of rhythm reanalysis, stacked shocks, and postdefibrillation pulse checks (January 1, 2002, to December 31, 2004). The primary outcome was survival to hospital discharge. The proportion of treated arrests that met inclusion criteria was similar for intervention and control periods (15.4% [134/869] versus 16.6% [374/2255]). Survival to hospital discharge was significantly greater during the intervention period compared with the control period (46% [61/134] versus 33% [122/374], P=0.008) and corresponded to a decrease in the interval from shock to start of chest compressions (28 versus 7 seconds). Adjustment for covariates did not alter the survival association. CONCLUSIONS: These results suggest the new resuscitation guidelines will alter the interface between defibrillation and cardiopulmonary resuscitation and in turn may improve outcomes. (+info)
The use of classroom training and simulation in the training of medical responders for airport disaster.
(78/217)
There is a dire need to have complementary form of disaster training which is cost effective, relatively easy to conduct, comprehensive, effective and acceptable. This will complement field drills training. A classroom-based training and simulation module was built by combining multiple tools: Powerpoint lectures, simulations utilising the Kuala Lumpur International Airport (KLIA) schematic module into 'floortop' model and video show of previous disaster drill. 76 participants made up of medical responders, categorised as Level 1 (specialists and doctors), Level 2 (paramedics), Level 3 (assistant paramedics) and Level 4 (health attendants and drivers) were trained using this module. A pre-test with validated questions on current airport disaster plans was carried out before the training. At the end of training, participants answered similar questions as post-test. Participants also answered questionnaire for assessment of training's acceptance. There was a mean rise from 47.3 (18.8%) to 84.0 (18.7%) in post-test (p<0.05). For Levels 1, 2, 3 and 4 the scores were 94.8 (6.3)%, 90.1 (11)%, 80.3 (20.1)% and 65 (23.4)% respectively. Nevertheless Level 4 group gained most increase in knowledge rise from baseline pre-test score (51.4%). Feedback from the questionnaire showed that the training module was highly acceptable. A classroom-based training can be enhanced with favourable results. The use of classroom training and simulation effectively improves the knowledge of disaster plan significantly on the back of its low cost, relatively-easy to conduct, fun and holistic nature. All Levels of participants (from specialists to drivers) can be grouped together for training. Classroom training and simulation can overcome the problem of "dead-document" phenomenon or "paper-plan syndrome". (+info)
The experience of Teesside helicopter emergency services: doctors do not prolong prehospital on-scene times.
(79/217)
BACKGROUND: The benefits of helicopter emergency medical services (HEMSs) attending the severely injured have been documented in the past. The benefits of doctors attending HEMS casualties have been demonstrated in particular in inner-urban and metropolitan areas. However, for UK regions with potentially less major trauma, concerns have been raised by ambulance services that a willingness of doctors to "stay and play" may lead to unnecessary delays on-scene without any additional benefit to the patient. AIMS: To identify factors that do prolong on-scene time, establish whether doctors "stay and play" on-scene compared with paramedics and document how often advanced medical skills may have to be used by HEMS doctors working outside the London HEMS environment. METHODS: Patient report form data were studied with regard to the number of and mean on-scene times of missions flown to (A) road-traffic collisions (RTCs), (B) other trauma calls (OTCs) and (C) medical emergencies. Trauma missions (categories A and B) were further subcategorised with regard to associated patient entrapment. Any advanced medical interventions (AMIs) performed by HEMS doctors were recorded and categorised. Finally, we looked at the difference in on-scene times for physician-paramedic partnerships (PPPs) and conventional paramedic crews (CPCs) for the above categories and subcategories. RESULTS: A total of 203 patient report forms were identified and examined. In all, 44.3% of missions were flown to RTCs with a further 44.3% for OTCs and 11.4% to medical emergencies. AMIs were performed by HEMS doctors in 34.1% of PPP missions, with a prehospital rapid sequence induction rate of 3.8%. Overall mean on-scene time was 25 min, with no difference for PPP and CPC missions. The mean on-scene time was prolonged by 6 min for RTCs (p = 0.006) and by 23 min for patient entrapment (p<0.001). No significant differences were found for the comparison between PPPs and CPCs in any of the subgroups A-C. However, there seemed to be a trend towards reduced on-scene times of PPPs for medical emergencies and patient entrapments. DISCUSSION: This study did not show any significant prolongation of mean on-scene times for PPP missions either overall or for any of the subgroups A-C. The fact that AMIs were performed in a large number of missions attended by HEMS doctors seems to further justify their current role in providing improved care at the roadside without leading to any delays in transfer to definitive care.

A national assessment of knowledge, attitudes, and confidence of prehospital providers in the assessment and management of child maltreatment.
(80/217)
OBJECTIVE: The goal was to assess the knowledge and confidence in recognition, management, documentation, and reporting of child maltreatment among a representative sample of emergency medical services personnel in the United States. METHODS: A questionnaire was developed and pilot-tested, with the input of experts in emergency medical services and child maltreatment, to assess knowledge, attitudes, confidence, and training needs regarding assessment and treatment of child maltreatment. The questionnaire was distributed nationally to a random sample of prehospital providers by using a previously validated sampling plan. RESULTS: Of 2863 surveys sent to prehospital providers, 1237 (43%) were returned. Most prehospital providers reported receiving < or = 1 hour of continuing medical education regarding child maltreatment. Most (78%) asked for additional educational opportunities, with only 3% stating that they required no additional training. Participants lacked knowledge regarding the developmental abilities of children, management of families in which child maltreatment is suspected, key elements of the history that should be noted, and the degree of suspicion necessary for reporting. CONCLUSIONS: Prehospital providers expressed confidence in their abilities to recognize and to manage cases of child abuse and neglect; however, significant deficiencies were reported in several critical knowledge areas, including identification of child maltreatment, interviewing techniques, and appropriate documentation.
