ABSTRACT

OBJECTIVE: To determine preschool children's response to a commercial back-up warning alarm in a mock setting of an automobile backing up. SETTING: Preschool parking lot in Albuquerque, New Mexico, USA. METHODS: With subjects acting as their own controls, 33 preschoolers were asked to walk behind a stationary vehicle twice. The first time, the control, no warning sound was emitted from the vehicle. The second time, the vehicle was placed in reverse gear triggering an alarm. Children's responses were recorded by a hidden video camera. Avoidance behavior by the child was considered a positive response. Location and distance to where the response occurred was measured. RESULTS: Thirty three children, 38-61 months, were studied. None responded to the alarm with avoidance behavior but 18 looked toward the vehicle or hesitated in their gait. CONCLUSION: Although over half of the children acknowledged the warning alarm, the device did not elicit avoidance behavior. Mere acknowledgment of the warning device would not prevent injury.

ABSTRACT

OBJECTIVE: To study emergency preparedness in public schools in a rural state. METHOD: Questionnaires were mailed to school nurses registered with the State Department of Education. Data collected included school nurse and staff training, school location, emergency equipment available, and Emergency Medical Service (EMS) access. RESULTS: Seventy-two percent of the surveys were returned after one or two mailings. They report little emergency training for both school nurses and school staff. Emergency equipment available varies widely: oxygen 20%, artificial airways 30%, cervical collars 22%, splints 69%. Equipment was more likely to be available in communities with populations of less than 200,000. Sixty-seven percent of schools activate EMS for a student and 37% for an adult annually. Eighty-four percent of schools have a less than 10-minute EMS response time. CONCLUSIONS: EMS activation to schools is a common occurrence. Schools are ill prepared to care for this acuity of student or staff as assessed by equipment and emergency training. Schools in smaller communities, however, are better prepared for emergencies.

ABSTRACT

Questionnaires given to school nurses were used to collect data regarding emergency asthma equipment and plans. Sixty-three percent reported <10 asthmatic visits per month, 25% reported 10-50, and 12% reported >50. Only 20% of school nurses reported that 75%-100% of asthmatic students had an emergency plan, and 24% did not know if asthmatic students had a plan. Only half of the nurses had input into the plan. Equipment varied: 16% had oxygen, 45% had peak flow meters, 0% had MDIs, and 20% had nebulizers available. Many asthmatic students lack emergency plans, and many school nurses are not involved in the plans.

ABSTRACT

OBJECTIVE: To compare pediatric ambulance patients transported for chief complaints of suicide, assault, alcohol, and drug intoxication (SAAD) with pediatric patients transported for all other chief complaints. METHODS: An out-of-hospital database for the primary transporting service in an urban area was analyzed for patients 0-20 years of age from 1992 to 1995. Chief complaints by age, gender, and billing status were analyzed. RESULTS: There were 17,722 transports. The SAAD group comprised 14.9% of all transports (suicide attempt 1.6%, assault 5.9%, alcohol intoxication 3.2%, and drug abuse 4.2%). The proportion of transports due to SAAD increased with age: 0-11-year-olds (4.2%); 11-16-year-olds (17.5%); and 17-20-year-olds (20.3%) (p = 0.0001). Genders were equally represented in the overall group, while males comprised 52.6% of the SAAD transports (p = 0.032). In the SAAD group, the majority of transports for assaults (55.9%) and alcohol (58.8%) involved males, while females were the majority in transports for suicide (52.3%) and drug abuse (66%) (p = 0.0001). Reimbursement sources differed, with those in the SAAD group less likely to be reimbursed by private or public (Medicaid, government) insurance (p < 0.0001) compared with the overall group. CONCLUSIONS: A substantial proportion of pediatric emergency medical services transports are for high-risk conditions. This patient population differs from the overall group by age distribution and reimbursement source.

ABSTRACT

STUDY OBJECTIVE: To determine whether implementation of a set of standardized pediatric telephone triage protocols results in consistent triage dispositions when applied by different operators. METHODS: A descriptive study with interrater comparisons was performed. Telephone interviews simulated the setting of a triage station in a university hospital-based pediatric emergency department. A mock parent presented 15 standardized respiratory cases in random order to 12 pediatric ED nurses. Nurses assigned patients' complaints to severity categories using 9 respiratory complaint protocols extracted from a commercially available pediatric telephone triage tool. Protocol selection and severity endpoints were recorded. Interobserver agreement among nurses was analyzed by the kappa statistic. Comparisons of operator characteristics and triage results were carried out by ANOVA. RESULTS: Interrater agreement in triage disposition among nurses was poor (kappa,.11; 95% confidence interval,.02 to.20). Protocol selection varied; the group used a mean of 3 different disposition-generating protocols per case. Disposition also varied, with up to 4 different severity endpoints per protocol in a given case. A post-hoc comparison of the mean disposition severity between nurses did not reach significance at an adjusted level (P =.04). Fifty-eight percent of the nurses felt confined by the protocols, and 42% admitted to at least 1 intentional deviation from them. CONCLUSION: It may not simply be assumed that the use of protocols will standardize care. This is particularly important in the case of triage, with current trends toward medical decisionmaking by less skilled providers with diminishing patient contact. Although triage protocols may be useful to guide clinical thinking, their consistency must be validated before they may be safely disseminated for general use.

ABSTRACT

OBJECTIVE: To compare pre-EMS intervention (bystander intervention) with EMS intervention (performed by fire department/EMS personnel) in the management of airway foreign bodies in children. METHODS: First-responding paramedic run reports for 1994 in the metropolitan area (city and county fire departments) pertaining to acute foreign body airway obstruction in children (aged 0-15 years) were reviewed. Data regarding age, gender, type of foreign body, method by which the airway was cleared, and mode of transportation were extracted. RESULTS: There were 103 runs with an age distribution as follows: 0-11 months 39.8%; 1-5 years 50.5%; and >6 years 9.7%. Fifty-eight (56.3%) involved males and 45 (43.7%) involved females. Eighty-five percent of the airways were cleared before EMS arrival. Thirty-eight percent were self-cleared by the child. The chance of airway clearance before EMS arrival increased with increasing age: 78% of the children aged 0-11 months, 88.5% of the children 1-5 years of age, and 100% of the children aged 6 years or older had their airways cleared before EMS arrival. Forty-four percent of the children were not transported, and 27% were transported by private vehicle. Coins and food were the two most common foreign bodies. CONCLUSION: The majority of airway foreign bodies were cleared before EMS arrival, especially in older children. This supports CPR training of new parents and the general population and has training implications for the EMS provider in managing the pediatric airway.

ABSTRACT

OBJECTIVE: To compare the initial emergency medical services (EMS) prehospital assessment of medical and traumatic cardiopulmonary arrest in the pediatric patient with that of the Office of the Medical Investigator (OMI) and assess differences and implications for EMS training and prevention. DESIGN: Retrospective review of ambulance run forms with the OMI autopsy confirmations. SETTING: An urban EMS system and the state Office of the Medical Investigator. PARTICIPANTS: Patients 15 years of age or less who were treated by prehospital personnel from November 1, 1990, to October 31, 1991, for a medical or traumatic arrest. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Ambulance runs were reported for 2,586 pediatric patients. Of these, 42 (1.6%) had suffered arrests, with 32 (76%) medical arrests and ten (24%) traumatic arrests. Children 1 year of age or less accounted for 75% of the medical arrests, while children more than 1 year of age accounted for 80% of the traumatic arrests (p = 0.003). Overall mortality was 81%. When EMS prehospital assessments of medical and traumatic arrests were compared with autopsy reports, there was good agreement for sudden infant death syndrome (SIDS) (kappa = 0.70), but poor agreement for child abuse (kappa = 0.37). CONCLUSION: The authors found good agreement between EMS prehospital assessments and autopsy diagnoses for identifying pediatric SIDS, but child abuse was not well identified prior to autopsy.

ABSTRACT

Many asthmatic children require assistance by emergency medical services (EMS) secondary to an acute asthma episode. What medication interventions are being utilized by EMS when responding to an asthma call for a child, and how does EMS management compare to home management given before ambulance arrival (pre EMS)? Sixty-one ambulance reports pertaining to acute asthma episodes in children aged 1 month to 15 years were collected and analyzed. There was no significant difference between likelihood to receive a beta 2-agonist nebulizer treatment pre-EMS arrival or by EMS. Oxygen was the most common EMS intervention.

ABSTRACT

To compare and contrast retrospective versus concurrent quality of care review processes in a Level I Trauma Center, we conducted a retrospective chart review of all pediatric trauma admissions in 1990 (n = 113) and compared it to the concurrent trauma quality assurance program for the same time period. Twenty-four percent (24%) of the patients reviewed in the retrospective study were identified by filters and reviewed through the concurrent process. In both the retrospective and concurrent review process problems in medical care problems, documentation, social and preventive elements of the case, and overall assessment of the patients' care were described. Overall, we found less than 50% agreement between the two reviews. The retrospective review identified medical care issues in 64% of cases, compared with a 44% error rate noted in the concurrent review (P < 0.07). Reviewers were more likely to note the absence of appropriate documentation, and overall assessment of the patients' care in the retrospective process (P < 0.0001). The retrospective review also highlighted issues related to the prevention of the injury and the patients' social situation, which were not considered by the concurrent review. Overall, we found the concurrent review appropriate for case by case medical management, while the retrospective review was relevant to a systems approach to the care of the injured child. To obtain a complete picture of the care of injured children, we recommend 1) a portion of charts be reviewed retrospectively in addition to ongoing concurrent review; or 2) the concurrent review add filters that are specific to pediatric issues and overall system issues.

ABSTRACT

Maintenance of fibroblasts in 0.5% serum results in viable but non-proliferative cells that may be analogous to fibroblasts in vivo. The synthesis of proteoglycans by human embryo lung fibroblasts in Eagle's minimal essential medium with 0.5% newborn-bovine serum or with 10% serum has been compared. A similar amount of [35S]sulphate-labelled glycosaminoglycan per cell was secreted by fibroblasts in 10% or 0.5% serum. 35SO42-incorporation into sulphated glycosaminoglycans was enhanced in 0.5% serum when expressed per mg of cell protein, but [3H]glucosamine incorporation was decreased. The charge density of these glycosaminoglycans was not changed as determined by ion-exchange chromatography. It was concluded that decreased protein/ cell resulted in an apparent increase in 35S-labelled glycosaminoglycan synthesis/mg of cell protein, whereas decreased uptake of [3H]glucosamine resulted in a decrease in their glucosamine labelling. The proteoglycans secreted by fibroblasts in 0.5% serum were similar in glycosaminoglycan composition, chain length and buoyant density to the dermatan sulphate proteoglycan, which is the major secreted component of cells in 10% serum. Larger heparan sulphate and chondroitin sulphate proteoglycans, which comprise about 40% of the total secreted proteoglycans of cultures in 10% serum, were greatly diminished in the medium of cultures in 0.5% serum. The proteoglycan profile of medium from density-inhibited cultures in 10% serum resembles that of proliferating cultures, indicating that lack of proliferation was not responsible for the alteration. The dermatan sulphate proteoglycan, participating in extracellular matrix structure, may be the primary tissue product of lung fibroblasts in vivo.

ABSTRACT

The synthesis and turnover of sulfate-labeled glycosaminoglycans(35S-GAGs) has been investigated in diploid human embryo fibroblasts during in vitro cellular aging. With progressive subcultivation, there was a decreased incorporation of Na2(35)SO4 into 35S-GAGs released to the medium, but not into those accumulated at the cell surface. The composition of 35S-GAGs found in extracellular medium, cell surface (removable by gentle proteolysis), and intracellular compartments of the culture after 48-hr labeling did not change significantly with progressive subcultivation. Pulse-labeled 35S-GAGs moved from intracellular to surface and extracellular compartments more slowly in late-passage cultures. Addition of 1 mM beta-xyloside to both early- and late-passage cultures produced a ten-fold enhancement of extracellular 35S-GAG production without a concomitant increase in surface-associated 35S-GAG. We interpret the data of this study to mean that secreted and cell-surface glycosaminoglycans represent different pools and that cellular aging has its effect primarily upon the secreted pool of glycosaminoglycans. Late-passage fibroblasts demonstrate marked decreases in proliferation, culture density, fibronectin matrix, and gap-junction formation. Our results suggest that glycosaminoglycan synthesis and composition are not intimately related to these parameters.
