Accusations that hospital staff have abused pediatric patients.

OBJECTIVE: Study objectives were to describe a hospital Child Protection Team's (CPT) efforts to develop and implement a protocol for systematic evaluation and management of accusations that hospital staff have abused pediatric patients, and to learn how to avoid problematic patient encounters and cope with existing accusations. METHOD: This study reports on a retrospective series of cases from one pediatric hospital between 1982 and 1996. It includes a survey of national children's hospitals' experience from 1990 through 1995. RESULTS: After initial complaints to our hospital's CPT, it became apparent that procedures were inadequate to protect the safety of patients and rights of the accused. A protocol for reporting, evaluation, and management of accusations was developed and implemented by the CPT. Thirty-four accusations of abuse of children by staff were reviewed. Seventeen of the physical abuse cases included bruising, fractures, rough handling, and verbal abuse. Eighteen sexual abuse complaints included touching and sexual statements. Complaints were substantiated in 23% of the accusations, and a third of the identified staff members were fired or resigned. Child victims had a high frequency of chronic illness. They and their families frequently had histories of prior abuse, mental illness, and social disarray. These factors made children more likely to become victims of real abuse and to misinterpret standard hospital procedures as abusive. All service areas of the hospital and types of hospital staff were accused of patient abuse. CONCLUSIONS: Few children's hospitals have formal protocols for internal management of or training programs to avoid complaints. Institutions and their staff who care for children should anticipate abuse complaints, train them in risk reduction methods, and develop accusation management plans.

The cause of infant and toddler subdural hemorrhage: a prospective study.

OBJECTIVE: To determine the frequency of child abuse and unintentional injury as a cause of infant and toddler subdural hemorrhage (SDH). METHODS: A prospective case series of a level I regional trauma center, regional children's hospital, and county medical examiner's office assessed consecutive children who were </=36 months old and had SDH. Children who had previously known hemorrhagic disease, previous neurosurgical procedure, previously recognized perinatal brain injury, meningitis, renal dialysis, and severe dehydration were excluded. Concurrent medical, retinal, skeletal, and social work abuse evaluation were measured. Etiologic assessment using predetermined criteria was conducted. RESULTS: From March 1995 through December 1998, 66 children were admitted with SDH. Abuse was confirmed in 39 (59%), unintentional injury in 15 (23%), and indeterminate cause in 12 (18%). The mean age of abused children was 8.7 +/- 8.1 months and of children with unintentional injuries was 19.1 +/- 10.0 months. The predominant presenting histories for abusive injury were a minor fall or no mechanism for 33 (84%) of 39 patients. All unintentional injuries resulted from a motor vehicle accident or other documented major trauma. Chronic or mixed acute and chronic SDH were found only in abused children (17 [44%] of 39) and in children whose injuries were indeterminate (8 [67%] of 12), not in children who were unintentionally injured (0 [0%] of 15). Long bone and/or rib fractures were found in 20 (51%) of 39 abused children but in only 1 unintentionally injured child. Retinal bleeding was present in 28 (72%) of 39 of the abused children. Only 1 of the 3 unintentionally injured children who had a retinal examination had bleeding, which was of the type associated with acute increased intracranial pressure. CONCLUSIONS: Nearly one fifth of infant and toddler SDH resulted from unintentional trauma. Of those without obvious unintentional trauma, 76% were corroborated to have been abused. Abused children were younger, more likely to have chronic SDH, and more likely to have multiple associated injuries. Their injury history usually was minor or absent.

Evaluation of resuscitation skills in new residents before and after pediatric advanced life support course.

OBJECTIVE: Acquisition of resuscitation skills taught in advanced resuscitation courses has not been evaluated. We sought to determine the interobserver reliability of a resuscitation performance skills checklist to assess resident performance of bag mask ventilation, intubation, defibrillation, and intraosseous vascular access, and to measure skill acquisition by entering residents after a pediatric advanced life support (PALS) course. DESIGN: The resuscitation skills of all 39 pediatric R1's in 2 university-based training programs were assessed immediately before and after completion of a PALS course just before starting residency. Independent observers scored and timed resident performance of bag mask ventilation, endotracheal intubation, intraosseous access, and defibrillation. Scores before and after the PALS course were compared. Four independent observers scored 4 residents' videotaped skills performance. Observers' scores for each resident were compared. RESULTS: Successful performance improved for bag mask ventilation from 62% to 97% after the PALS course; for successful endotracheal intubation, from 64% to 90%; for successful intraosseous needle placement, from 54% to 92%; and for successful defibrillation, from 77% to 97%. Interobserver reliability was high for continuous and noncontinuous variables. CONCLUSIONS: New residents demonstrated significant acquisition of pediatric resuscitation skills immediately after completion of the PALS course. The skills performance checklist has excellent interobserver reliability and is a useful tool for evaluation of other training venues.

Pediatric residents in the emergency department: what is their experience?

STUDY OBJECTIVE: We sought to describe the spectrum of illness and number of patients seen by pediatric residents rotating through a pediatric ED. METHODS: Our study was set in the ED of a 200-bed referral children's hospital providing services exclusive of major trauma. We conducted a retrospective review of the database of all visits to the ED between July 1992 and June 1995. Our subjects were 19 pediatric residents who started residency in July 1992 and ended residency in June 1995. Ninety-one other pediatric residents completed individual ED rotations during the same period. RESULTS: The study ED had 70,129 visits between July 1, 1992, and June 30, 1995. The study residents saw a median of 467 patients per resident (range, 290 to 604) during their 3-year residencies. The range of patients seen per resident for the diagnosis of asthma was 35 to 86, that for otitis media was 16 to 110, and that for fever or sepsis was 17 to 62. Similarly large ranges were seen for other diagnoses evaluated and procedures performed by residents. The proportions of the study residents who never saw a case of pyloric stenosis, intussusception, or diabetic ketoacidosis in the ED were 37%, 32%, and 32%, respectively. CONCLUSION: The number and type of patients seen by individual residents in this study showed significant variation. Many illnesses were not seen frequently enough for every resident to develop competence solely on the basis of clinical experience during ED rotations. A computerized, easily accessible ED database can be used to track the experience of individual residents or groups of residents. Such tracking would allow residents and program directors to identify areas that may require alternate educational strategies and would also document the residents' experience for future credentialing.

Misrepresentation of authorship by applicants to pediatrics training programs.

PURPOSE: To determine whether applicants to pediatrics residency and fellowship programs misrepresented authorship of publications. METHOD: The authors sampled 1995 applications to the University of Washington School of Medicine's pediatrics residency program and pediatrics pulmonary fellowship program. They submitted all publications claimed in the submitted applications to extensive efforts to authenticate both their existence and authorship. RESULTS: Among the 404 pediatrics residency program applications studied, 147 claimed authorship of publications; 29 (19.7%) of these contained at least one unverifiable publication. Of the 401 publications claimed in the 147 applications, 41 (10.2%) could not be confirmed. Among 31 fellowship applications, 14 claimed publications. At least one citation was unverifiable for each of the 14 applications. Of the total 77 publications claimed, 31 (40%) could not be confirmed. CONCLUSION: Misrepresentation occurs on graduate medical education applications; solutions are needed to address this problem.

An ethics curriculum for the pediatric residency program. Confronting barriers to implementation.

BACKGROUND: The 1997 Residency Review Committee requirements in pediatrics mandate a structured curriculum in medical ethics for all accredited pediatric residency programs. To our knowledge, there are no published models for the development of an ethics curriculum for pediatric residents. Several obstacles may confront those attempting to begin an ethics teaching program. OBJECTIVE: To describe the successful implementation of a structured ethics curriculum for pediatric residents. METHODS: Our program was designed to overcome the following obstacles: (1) time constraints of faculty and residents, (2) scheduling difficulties and lack of continuity, (3) attitudes of residents toward the material, and (4) inadequate ethics training among faculty. In addition to traditional topics in medical ethics, the curriculum focuses on issues that confront residents primarily during their training, issues that may shape their professional values in important ways. RESULTS: This ethics curriculum has been successfully implemented in our own program and offers solutions to common barriers faced by those seeking to implement an ethics curriculum for pediatric residents. CONCLUSION: We present the ethics curriculum currently in use at our institution as a tool that may be adopted as it stands or as altered by others as they develop their own program's ethics curriculum. We believe the proposed curriculum directly confronts many of the barriers to successful ethics education of pediatric residents.

Epidural hemorrhage: is it abuse?

OBJECTIVE: To determine whether children presenting with epidural hemorrhage (EDH) are as likely to have been abused as are children presenting with subdural hemorrhage (SDH). DESIGN: Retrospective chart review. SETTING: Level I regional trauma center and a regional children's hospital. PATIENTS: All children at both institutions 3 years old or younger with a diagnosis of EDH or SDH identified by a search of the computerized trauma registry and hospital medical records from 1985 through 1991. MEASUREMENT AND RESULTS: Complete records were found for 93 of 94 eligible subjects. The diagnosis of accidental or inflicted injury was ascertained from the patient's hospital medical record or the records of Child Protective Services. Of all subjects (n = 93), 52% (48/93) were male and the median age was 15 months. Abuse was diagnosed in 47% (28/59) of children with SDH and 6% (2/34) of those with EDH. Other significant injuries were found in 47% of children with SDH and 18% of children with EDH. There was no statistically significant difference between the two groups with respect to the likelihood of identifying a skull fracture, the need for surgical evacuation of the hemorrhage, or mortality. CONCLUSIONS: Our data are consistent with current biomechanical concepts of intracranial injury. EDHs results from brief linear contact forces that commonly occur in unintentional falls. SDHs are caused by global high-energy rotational acceleration/deceleration forces that are commonly generated in episodes of abuse. Compared with SDH, EDH rarely results from abuse.

Buffered lidocaine: analgesia for intravenous line placement in children.

OBJECTIVES: To evaluate the effectiveness of intradermal buffered lidocaine as analgesia before intravenous line (i.v.) placement in children. METHODS: This was a randomized clinical trial undertaken in the emergency department (ED) of a regional children's hospital. Participants were children 8 to 15 years old, seen in the ED and in need of i.v. lines. They were enrolled by three ED nurses. Participants were randomized to receive either intradermal buffered lidocaine or no analgesia. Before placement of the i.v. line, patients recorded the amount of pain they were in (baseline pain) on a visual analog pain scale. The primary outcome measure was amount of pain caused by the initial i.v. attempt, even if that attempt was unsuccessful. This was recorded by the participant on a visual analog scale. Demographic characteristics, the number of attempts to successful placement, and the time required to place the i.v. line were also recorded. Differences in pain of initial i.v. attempt and time to place the i.v. line were evaluated with the Mann-Whitney U test. Differences in success of i.v. line placement were evaluated with the chi 2 test. RESULTS: Fifty-nine patients completed the study. Thirty received buffered lidocaine, and 29 received no analgesia before i.v. line placement. There was no significant difference between the two groups with regard to baseline pain or demographic characteristics. The median level of pain of the initial i.v. attempt as measured by the visual analog scale was 2.3 in the buffered-lidocaine group and 4.4 in the no-lidocaine group. Thirty-three percent of patients in the lidocaine group and 28% percent in the no-lidocaine group required more than one i.v. attempt. The median time to i.v. line placement was 10 minutes in the lidocaine group and 6 minutes in the no-lidocaine group. CONCLUSIONS: Use of intradermal buffered lidocaine is an effective way to diminish the pain of i.v. line placement in children 8 to 15 years of age. There was no difference in i.v. success rate in this study; however, larger numbers of patients would be required to detect statistically significant differences. We recommend the routine use of intradermal buffered lidocaine for analgesia before i.v. line placement in older children in all but emergent situations.

Acute-phase reactants and acute bacterial otitis media.

OBJECTIVE: To determine if the erythrocyte sedimentation rate and C-reactive protein level are elevated in uncomplicated acute bacterial otitis media. DESIGN: Investigator-blinded, antibiotic efficacy trial. SETTING: The emergency department of an urban regional children's hospital with 24,000 annual visits. PARTICIPANTS: Thirty-one children with symptoms of acute bacterial otitis media of 7 days' duration or less. SELECTION PROCEDURE: Volunteer sample. INTERVENTIONS: Tympanocentesis, oral antibiotics for 10 days, and three follow-up visits in the next 30 days. MEASUREMENTS/RESULTS: The erythrocyte sedimentation rate and C-reactive protein level were obtained at time of entry into the antibiotic study. Seventeen patients (55%; 95% confidence interval, 37% to 72%) had either an erythrocyte sedimentation rate above 20 mm/h or a C-reactive protein level above 8 mg/L. Eleven patients (35%) had a recurrent episode of acute bacterial otitis media during the follow-up period. The relative risk of recurrence of otitis media given an elevated erythrocyte sedimentation rate or C-reactive protein level was 8.24 (95% confidence interval, 1.20 to 56.74; Fisher's Exact Test; P = .007). CONCLUSIONS: Clinicians who use elevated acute-phase reactants as possible indicators of invasive bacterial infections should be aware that an elevated erythrocyte sedimentation rate or C-reactive protein level is also consistent with acute bacterial otitis media. An elevated erythrocyte sedimentation rate or C-reactive protein level also appears to be associated with an increased risk of recurrence of acute bacterial otitis media. If these findings can be confirmed in a larger study, the erythrocyte sedimentation rate or C-reactive protein level could be used to assess the risk of recurrent otitis media.

Risk factors for childhood sledding injuries: a case-control study.

We report the results of a case-control study designed to identify modifiable risk factors for childhood sledding injuries. Cases included all children injured while sledding (n = 17) during a five-day winter storm who presented for care to a Seattle pediatric emergency department. Two controls were chosen randomly for each case from children who presented to the same emergency department during the ensuing two months for any illness that did not require hospitalization. To qualify as controls, children had to have sledded during the same five-day period but not sustained an injury requiring medical attention. Data were collected on cases and controls using a telephone questionnaire. Analysis of risk factors revealed a significant increase in risk of injury for children who sledded in streets versus those who sledded in a park (OR = 5.1; 95% CI = 1.1-24.1), those who sledded without adult supervision (OR = 5.6; 95% CI = 1.1-26.9), and those whose parents had an annual income > or = $50,000 (OR = 5.7; 95% CI = 1.5-20.8). No difference in risk of injury was found regarding the type of sled used, the number of children, or their position on the sled or for those children with a history of prior sledding experience. We conclude that safe alternatives to sledding in the streets and an increase in adult supervision may reduce the number of childhood sledding injuries.

A unique "mini" pepsinogen isolated from bullfrog esophageal glands.

The evolutionary homology of pepsinogens was further evaluated by isolating and characterizing the pepsinogen of the esophageal glands of Rana catesbeiana. Like other pepsinogens, this esophageal enzyme was activated by acid; the resulting pepsin was optimally active between pH 1.4 and 2.0, and was irreversibly denatured above pH 7.0. Chromatography on DEAE-cellulose at pH 7.0 separated four acid protease fractions corresponding to pepsinogens B, D, A, and C. Hydroxylapatite chromatography of the major peptic fraction, pepsinogen A, followed by rechromatography on DEAE-cellulose at pH 8.5 yielded pure pepsinogen A which was free of detectable contaminants. Estimation of molecular weight by gel filtration on Sephadex G-75, by polyacrylamide gel electrophoresis in 0.1% SDS and by sedimentation equilibrium gave values of 31,500, 33,500, and 33,700, respectively. These studies suggest that the difference between bullfrog and other pepsinogens is located in a 90 to 110 amino acid (Mr 9,000 to 11,000) region of the molecule which must be remote from the catalytic and immunogenic sites. This lower molecular weight pepsinogen should thus provide a simpler molecular model for study of the catalytic and immunogenic properties. The pepsinogen from bullfrog gastric mucosa was found to have similar properties which suggested that gastric and esophageal pepsinogens of bullfrog are derived from a common ancestral origin. This archetypic pepsinogen may have undergone deletions late in evolution to render modern bullfrog pepsinogen structurally dissimilar from other described pepsinogens. The modern bullfrog enzyme has retained peptic enzymatic activity despite these evolutionary changes.
