The physical, psychological, and socioeconomic costs of pediatric trauma.

This prospective study examined the physical, psychological, and socioeconomic effects of injuries on children and their immediate families. Ninety-two injured children admitted with minor (ISS less than 16) or major (ISS greater than or equal to 16) injuries were compared with a control group of 59 children admitted during the same period with acute appendicitis. The two populations were similar in mean age, sex ratio, parental age and work status, and number of siblings. The parents of the injured children had a lower level of education than those of the controls. Fifty-four percent of the minor injury patients and 71% of the major injury patients had persistent physical limitations at 12 months in contrast to none of the controls. Thirty-eight percent of minor injury patients had pre-existing behavioral disturbances compared with 14% of major injury patients and 10% of controls. Behavioral disturbances among major trauma patients showed a sharp rise to 41% at 12 months and tended to persist in cases with continuing physical limitations. The major injury patients and those with significant head injuries exhibited a decrease in academic performance; minor injury patients and those without head injury showed no change. Maternal malaise rose sharply to about 40% in both injury groups in contrast to 7% in the controls and was more common in the presence of persistent physical limitations. Only 73% of families in the major injury group had returned to normal family life compared with 87% of the minor injury group and 100% of controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Preventable pediatric trauma deaths in a metropolitan region.

All pediatric trauma deaths occurring in metropolitan Toronto (population, 2.2 million) in 1986 were analyzed from the regional coroner's records. Injuries sustained were scored using the Abbreviated Injury Scale (1985; AIS) and Injury Severity Score (ISS). Victims with injuries graded AIS 6 (any region), AIS 5 head/neck (excluding acute epidural hematoma), or ISS greater than 59 were deemed unsalvageable. All other injuries were considered survivable and the deaths from them preventable. Use of these objective criteria indicated that 8/38 of the children (21%) who died from trauma had survivable injuries. Since in three cases medical aid was not sought because of social circumstances, 5/38 (13%) was considered a realistic estimate of preventable death rate (PDR). These results suggest that when objective criteria are used, the PDR in pediatric trauma may be less than that reported in adult trauma victims. Defining the PDR on the basis of objective criteria may prove useful in the conduct of further studies of this kind and permit valid comparisons to be made.

Splenic injury: a 5-year update with improved results and changing criteria for conservative management.

The policy of conservative nonoperative management of the injured spleen is reviewed, and recommendations are made to improve this mode of therapy. From 1981 to 1986, 75 patients were admitted with diagnosed splenic injury. Of thes, ten were operated on (four splenorrhaphies, three total splenectomies, one partial splenectomy; in two, the spleen had stopped bleeding spontaneously) and three died, all from causes unrelated to splenic trauma. Only 23% of the patients treated nonoperatively required blood transfusions, and the length of both hospital stay and time spent in the ICU was reduced. The results of this review show that, in comparison with our previous 5-year report, the number of patients treated without surgery increased from 70% to 87%, those receiving blood transfusions decreased from 36% to 23%, and the number undergoing a splenectomy decreased from 24% to 4%. These data suggest that almost all children with splenic injury can be successfully treated without an operation, those who are hemodynamically stable do not require ICU care, and the total hospital stay for uncomplicated splenic injury can be limited to seven days. A laparotomy can be safely reserved for patients with immediate massive hemorrhage or with transfusion requirements of greater than 40 mL/kg.

Splenic injury: a 5-year update with improved results and changing criteria for conservative management.

The policy of conservative nonoperative management of injured spleens is reviewed and recommendations are made to improve this mode of therapy. From 1981 to 1986, 75 patients were admitted with diagnosed splenic injury. Of these, ten were operated on (4 splenorrhaphies, 3 total splenectomies, 1 partial splenectomy) and three died, all from causes unrelated to splenic trauma. Only 23% of the patients treated nonoperatively required blood transfusions, and the length of both hospital stay and time spent in the intensive care unit (ICU) was reduced. The results of this review show that, in comparison with our previous 5-year report, (1) the number of patients treated without surgery rose from 70% to 87%, (2) those receiving blood transfusions dropped from 36% to 23%, and (3) the number undergoing a splenectomy fell from 24% to 4%. These data suggest that (1) most children with splenic injury can be successfully treated without operation, (2) those who are hemodynamically stable do not require ICU care, and (3) the total hospital stay for uncomplicated splenic injury can be limited to seven days. A laparotomy can be safely reserved for patients with immediate massive hemorrhage or with transfusion requirements of greater than 40 mL/kg.

Functional outcome in pediatric trauma.

Two hundred fifty consecutive children hospitalized with severe injuries (at least one injury with an Abbreviated Injury Score [AIS] greater than or equal to 4 or two or more injuries with AIS scores greater than or equal to 2) were studied to determine their functional status at discharge and 6 months later using questions from the RAND Health Insurance Study (HIS) and the Glasgow Outcome Scale (GOS). Of the 217 surviving patients, 190 (88%) had one or more functional limitations by the HIS scale at discharge. Ten (5%) were in a vegetative state, 40 (18%) severely disabled, 97 (45%) moderately disabled, and 70 (32%) healthy by the GOS. Six-month followup was complete for 156 patients. Of these, 84 (54%) had one or more functional limitations by the HIS scale. Seven (4%) were in a vegetative state, 17 (11%) severely disabled, 50 (32%) moderately disabled, and 82 (53%) healthy by the GOS. A substantial proportion of the whole group of children hospitalized for the treatment of severe injuries had ongoing physical disabilities that limited their participation in normal activities 6 months after they were discharged. This suggests a need for greater emphasis on the rehabilitation of pediatric trauma patients.

Evaluation of pediatric trauma care in Ontario.

Three hundred sixty-seven consecutive pediatric trauma deaths which occurred in Ontario between 1985 and 1987 were analyzed from the coroners' records. Injuries were classified as survivable or unsurvivable, and a preventable death rate of 20% was identified. Rural preventable deaths occurred mainly before arrival at hospital, but 55% of urban preventable deaths occurred in hospitals. The causes of death in children with survivable injury suggest that the institution of prehospital resuscitation and improvement in trauma care education for physicians might reduce mortality. The high incidence of unsurvivable injury suggests that injury prevention will be more cost effective in the long term.

Evaluating a pediatric trauma program: effectiveness versus preventable death rate.

We compared effectiveness (E), the proportion of severely injured patients who were salvageable and survived, to the preventable death rate (PDR) over three consecutive 1-year periods. Severely injured patients were those with at least one injury with an Abbreviated Injury Score (AIS) of greater than or equal to 4. Those with one fatal injury (AIS greater than or equal to 6), a critical head injury (AIS greater than or equal to 5) apart from acute epidural hematoma, or massive multiple injuries (Injury Severity Score greater than 59) were considered nonsalvageable; the remainder were considered salvageable. In the first year, six of 74 salvageable patients died, in the second year five of 76, and in the third year one of 69. The PDR rates were 0.32 (6/19), 0.23 (5/22), and 0.06 (1/17), respectively. There was no significant difference in the E of our trauma program over the 3 years. The apparent improvement in PDR in the second and third years resulted from an increased number of deaths among nonsalvageable patients and fewer deaths among salvageable patients. This finding demonstrates that PDR is sensitive to case mix and not just quality of care, and confirms the superiority of E over PDR for assessing a trauma program.

Injury scoring systems in children.

Injury scoring systems are used to describe groups or individuals for purposes of epidemiologic studies, quality assurance or triage. The two most widely used methods are the injury severity score (ISS) and the trauma score (TS). In this paper, the authors describe their experience with these two methods in a group of 175 severely injured children. They found both to be reliable and valid but found the ISS the more useful of the two for various practical reasons.

The pediatric passenger: trends in seatbelt use and injury patterns.

Injury patterns and use of passenger restraints were studied in 91 children injured while riding in motor vehicles and admitted to The Hospital for Sick Children, Toronto, from June 1984 through December 1985. Of theses, 44 had used restraints and 38 had not. Nine were excluded from the study because restraint use could not be determined. Age and sex distributions were closely matched in both study groups. The no-restraint group had more massive head injuries, thoracic injuries, and liver and spleen injuries than the restraint group. Classic "seatbelt syndrome" injuries were seen in the seatbelt group. The overall Injury Severity Scores were not significantly different between the groups. Despite mandatory legislation, many children do not use restraints, and many who do still suffer severe or fatal injuries. We conclude that better compliance with existing passenger restraint laws and more effective restraint systems are needed.
