Evaluation of guidelines for emergency triage assessment and treatment in developing countries.
(1/64)
AIM: To evaluate performance of a simplified algorithm and treatment instructions for emergency triage assessment and treatment (ETAT) of children presenting to hospital in developing countries. METHODS: All infants aged 7 days to 5 years presenting to an accident and emergency department were simultaneously triaged and assessed by a nurse and a senior paediatrician. Nurse ETAT assessment was compared to standard emergency advanced paediatric life support (APLS) assessment by the paediatrician. Sensitivity, specificity, and predictive values were calculated and appropriateness of nurse treatments was evaluated. RESULTS: The ETAT algorithm as used by nurses identified 731/3837 patients (19.05%); 98 patients (2.6%) were classified as needing emergency treatment and 633 (16.5%) as needing priority assessment. Sensitivity was 96.7% with respect to APLS assessment, 91.7% with respect to all patients given priority by the paediatrician, and 85.7% with respect to patients ultimately admitted. Specificity was 90.6%, 91.0%, and 85.2%, respectively. Nurse administered treatment was appropriate in 94/102 (92.2%) emergency conditions. CONCLUSIONS: The ETAT algorithm and treatment instructions, when carried out by nurses after a short specific training period, performed well as a screening tool to identify priority cases and as a treatment guide for emergency conditions.

Can nurses working in remote units accurately request and interpret radiographs?
(2/64)
OBJECTIVE: Recent changes in the NHS have seen nurses take on roles that are traditionally filled by doctors, leading to the development of emergency nurse practitioners (ENPs). In addition to this, increasing interest has focused on telemedicine (literally, medicine at a distance) as a way of supporting remote emergency departments and minor injuries units from larger centres. The vast majority of these consultations are related to peripheral limb trauma and require a radiograph to be viewed as an integral part of the telemedical consultation. The aim of this study was therefore to determine whether nurses working alone in a peripheral unit are able to appropriately request, and accurately interpret, peripheral limb radiographs. METHODS: In this prospective study the four qualified nurses working in a peripheral unit were permitted to request a defined set of radiographs after limb trauma. A written protocol for nurse requested radiographs was supported by individual teaching sessions. At the time that the radiograph was requested basic demographic details were recorded and the patient was also assessed by two senior doctors in emergency medicine, one in person and one via a telemedicine link, both of whom independently considered whether the radiograph requested by the nurse was appropriate in that patient. Nursing staff were also asked to provide a provisional interpretation of each film, and this was compared with a gold standard derived from the interpretations of the two emergency physicians who had seen the patient and the final radiologist's report. RESULTS: The first 300 patients who had a radiograph requested by a member of the nursing staff were studied over a period of 12 months. Altogether 93 radiographs (31%) were positive for recent bony trauma or radio-opaque foreign body. Eleven radiographs (3.7%) were judged by both emergency physicians to be inappropriate. Three radiographs (1%) were requested outside the limits of the protocol, but all three were judged to be appropriate and occurred within the first two months of the study. A total of 32 (10.7%) of the radiographs were incorrectly interpreted by nursing staff with 26 false positives, four false negatives and two cases where the nurse observed an abnormality but failed to identify it correctly. The sensitivity of nurse interpretation was therefore 96%, with a specificity of 87%. CONCLUSION: Experienced nurses, working without continuous medical supervision in a remote unit, are able to request appropriate radiographs of the peripheral limbs. Nurses requesting radiographs in this way can also interpret these films to a high standard, though with a tendency to err on the side of caution, generating many more false positive results than false negatives.

Patient-family-nurse interactions in the trauma-resuscitation room.
(3/64)
BACKGROUND: Controversy about the presence of patients' family members in the emergency department has centered on the trauma-resuscitation room. Little is known about interactions of patients' family members with the patients and with nurses or about the ramifications of the presence of patients' family members at the bedside. OBJECTIVES: To describe behavioral responses offamily members of patients and the interactions of thefamily members with nurses and the patient in the trauma room. METHODS: A secondary analysis was done of 193 videotapes of trauma room care. Of these, 88 tapes showed the presence of patients' family members, for a total of 42 hours. Qualitative ethology and a model of suffering as a scaffold were used to analyze verbal and nonverbal interactions between nurses, patients' family members, and patients. Behaviors and verbal interactions of patients and their families were coded as to persons who were enduring and persons who were emotionally suffering. Categories were described. RESULTS: Whether a patient's family members entered the trauma room depended on the patients condition, the patient's behavioral state, and the nature of the treatments. Categories of interactions were families learning to endure, patients failing to endure, family emotionally suffering and patient enduring, patient and family enduring, and resolution of enduring. The interaction style of the nurses involved was particular to each of these states. Two instances of inappropriate interactions occurred. CONCLUSIONS: Nurses can use the Model of Suffering as a framework to assess behavioral and emotional states and to select appropriate strategies to comfort patients' family members. (+info)
Self perceived work related stress and the relation with salivary IgA and lysozyme among emergency department nurses.
(4/64)
AIMS: To assess and compare the self perceived work related stress among emergency department (ED) and general ward (GW) nurses, and to investigate its relation with salivary IgA and lysozyme. METHODS: One hundred and thirty two of 208 (63.5%) registered female ED and GW nurses participated in the study. A modified mental health professional stress scale (PSS) was used to measure self perceived stress. ELISA methods were used to determine the salivary IgA and lysozyme levels. RESULTS: On PSS, ED nurses had higher scores (mean 1.51) than GW nurses (1.30). The scores of PSS subscales such as organisational structure and processes (OS), lack of resources (RES), and conflict with other professionals (COF) were higher in ED than in GW nurses. ED nurses had lower secretion rates of IgA (geometric mean (GM) 49.1 micro g/min) and lysozyme (GM 20.0 micro g/min) than GW nurses (68.2 micro g/min, 30.5 micro g/min). Significant correlations were observed between PSS and log IgA and lysozyme secretion rates. OS, RES, and COF were correlated with log IgA and lysozyme levels. CONCLUSION: ED nurses, who reported a higher level of professional stress, showed significantly lower secretion rates of salivary IgA and lysozyme compared to GW nurses. Salivary IgA and lysozyme were inversely correlated with self perceived work related stress. As these salivary biomarkers are reflective of the mucosal immunity, results support the inverse relation between stress and mucosal immunity. (+info)
Emergency nurse practitioners: a three part study in clinical and cost effectiveness.
(5/64)
AIMS: To compare the clinical effectiveness and costs of minor injury services provided by nurse practitioners with minor injury care provided by an accident and emergency (A&E) department. METHODS: A three part prospective study in a city where an A&E department was closing and being replaced by a nurse led minor injury unit (MIU). The first part of the study took a sample of patients attending the A&E department. The second part of the study was a sample of patients from a nurse led MIU that had replaced the A&E department. In each of these samples the clinical effectiveness was judged by comparing the "gold standard" of a research assessment with the clinical assessment. Primary outcome measures were the number of errors in clinical assessment, treatment, and disposal. The third part of the study used routine data whose collection had been prospectively configured to assess the costs and cost consequences of both models of care. RESULTS: The minor injury unit produced a safe service where the total package of care was equal to or in some cases better than the A&E care. Significant process errors were made in 191 of 1447 (13.2%) patients treated by medical staff in the A&E department and 126 of 1313 (9.6%) of patients treated by nurse practitioners in the MIU. Very significant errors were rare (one error). Waiting times were much better at the MIU (mean MIU 19 minutes, A&E department 56.4 minutes). The revenue costs were greater in the MIU (MIU pound 41.1, A&E department pound 40.01) and there was a great difference in the rates of follow up and with the nurses referring 47% of patients for follow up and the A&E department referring only 27%. Thus the costs and cost consequences were greater for MIU care compared with A&E care (MIU pound 12.7 per minor injury case, A&E department pound 9.66 per minor injury case). CONCLUSION: A nurse practitioner minor injury service can provide a safe and effective service for the treatment of minor injury. However, the costs of such a service are greater and there seems to be an increased use of outpatient services. (+info)
Computer assisted assessment and advice for "non-serious" 999 ambulance service callers: the potential impact on ambulance despatch.
(6/64)
OBJECTIVE: To investigate the potential impact for ambulance services of telephone assessment and triage for callers who present with non-serious problems (Category C calls) as classified by ambulance service call takers. DESIGN: Pragmatic controlled trial. Calls identified using priority dispatch protocols as non-serious were allocated to intervention and control groups according to time of call. Ambulance dispatch occurred according to existing procedures. During intervention sessions, nurses or paramedics within the control room used a computerised decision support system to provide telephone assessment, triage and, if appropriate, offer advice to permit estimation of the potential impact on ambulance dispatch. SETTING: Ambulance services in London and the West Midlands. SUBJECTS: Patients for whom emergency calls were made to the ambulance services between April 1998 and May 1999 during four hour sessions sampled across all days of the week between 0700 and 2300. MAIN OUTCOME MEASURES: Triage decision, ambulance cancellation, attendance at an emergency department. RESULTS: In total, there were 635 intervention calls and 611 controls. Of those in the intervention group, 330 (52.0%) were triaged as not requiring an emergency ambulance, and 119 (36.6%) of these did not attend an emergency department. This compares with 55 (18.1%) of those triaged by a nurse or paramedic as requiring an ambulance (odds ratio 2.62; 95% CI 1.78 to 3.85). Patients triaged as not requiring an emergency ambulance were less likely to be admitted to an inpatient bed (odds ratio 0.55; 95% CI 0.33 to 0.93), but even so 30 (9.2%) were admitted. Nurses were more likely than paramedics to triage calls into the groups classified as not requiring an ambulance. After controlling for age, case mix, time of day, day of week, season, and ambulance service, the results of a logistic regression analysis revealed that this difference was significant with an odds ratio for nurses:paramedics of 1.28 (95% CI 1.12 to 1.47). CONCLUSIONS: The findings indicate that telephone assessment of Category C calls identifies patients who are less likely to require emergency department care and that this could have a significant impact on emergency ambulance dispatch rates. Nurses were more likely than paramedics to assess calls as requiring an alternative response to emergency ambulance despatch, but the extent to which this relates to aspects of training and professional perspective is unclear. However, consideration should be given to the acceptability, reliability, and cost consequences of this intervention before it can be recommended for full evaluation. (+info)
Family presence during cardiopulmonary resuscitation and invasive procedures: practices of critical care and emergency nurses.
(7/64)
BACKGROUND: Increasingly, patients' families are remaining with them during cardiopulmonary resuscitation and invasive procedures, but this practice remains controversial and little is known about the practices of critical care and emergency nurses related to family presence. OBJECTIVE: To identify the policies, preferences, and practices of critical care and emergency nurses for having patients' families present during resuscitation and invasive procedures. METHODS: A 30-item survey was mailed to a random sample of 1500 members of the American Association of Critical-Care Nurses and 1500 members of the Emergency Nurses Association. RESULTS: Among the 984 respondents, 5% worked on units with written policies allowing family presence during both resuscitation and invasive procedures and 45% and 51%, respectively, worked on units that allowed it without written policies during resuscitation or during invasive procedures. Some respondents preferred written policies allowing family presence (37% for resuscitation, 35% for invasive procedures), whereas others preferred unwritten policies allowing it (39% for resuscitation, 41% for invasive procedures), Many respondents had taken family members to the bedside (36% for resuscitation, 44% for invasive procedure) or would do so in the future (21% for resuscitation, 18% for invasive procedures), and family members often asked to be present (31% for resuscitation, 61% for invasive procedures). CONCLUSIONS: Nearly all respondents have no written policies for family presence yet most have done (or would do) it, prefer it be allowed, and are confronted with requests from family members to be present. Written policies or guidelines for family presence during resuscitation and invasive procedures are recommended. (+info)
Mapping the range and scope of emergency nurse practitioner services in the Northern and Yorkshire Region: a telephone survey.
(8/64)
OBJECTIVE: To map the range and scope of emergency nurse practitioner (ENP) services in the Northern and Yorkshire Region as part one of a three phased study investigating the developing role of the ENP on a multi-professional context. METHODS: A telephone survey was conducted in the 48 hospital trusts within the region. Semi-structured interviews were arranged with the senior nurses responsible for accident and emergency services in responding departments. Data collection entailed completion of a form comprising 14 open-ended questions designed to elicit information about the range and scope of ENP services (as defined by the Royal College of Nursing). Data were analysed using descriptive statistics. RESULTS: Interviews were conducted at 35 (73%) of the sites, 22 (63%) of which had an ENP service as defined above. Wide variation was found in the range of services in relation to: hours/days of availability; age range and sources of referrals of patients accessing the service; clinical caseloads of ENPs and the referral pathways to other services. CONCLUSION: The findings from the survey highlight the organic, context specific nature of ENP role developments in response to national government initiatives, professional agendas, and local service needs.
