Predictors of ventriculoperitoneal shunt pathology.

BACKGROUND: Diagnosis of ventriculoperitoneal (VP) shunt pathology remains a dilemma in patients with nonspecific constitutional signs and symptoms. Eosinophilia has been described in association with shunt infection and malfunction. Our purpose was to further define the relationship of eosinophilia and shunt pathology and to determine other predictors of VP shunt infection and malfunction. METHODS: Records of all patients admitted with a suspected VP shunt infection or malfunction were reviewed. The following data were abstracted: age; reason for and age at initial shunt placement; number of revisions; date of last revision; history of fever or vomiting; ventricular fluid cell count; differential and culture; complete blood count and differential; need for shunt revision or replacement; and use of antibiotics. After exclusion of patients admitted for initial shunt placement, the remainder were divided into three groups: those with shunt infection; those with shunt malfunction; and those without documented infection or malfunction. RESULTS: Of 12 patients with shunt infection and 69 with shunt malfunction, 2 and 11, respectively, had eosinophilia defined as > or =5%. The presence of eosinophilia had a 96% positive predictive value for shunt pathology and raised the pretest probability of pathology from 84% to a post test probability of 96%. The combination of fever history and ventricular fluid neutrophils >10% had a 99% specificity for shunt infection, had a 93 and 95% positive and negative predictive value, respectively, and raised the pretest probability of infection from 12% to a posttest probability of 92%. CONCLUSIONS: In patients suspected of having a VP shunt malfunction, the presence of > or =5% eosinophils in the ventricular fluid indicates shunt pathology. The combination of fever and ventricular fluid neutrophils > 10% is predictive of shunt infection.

The objective structured clinical examination: a step in the direction of competency-based evaluation.

BACKGROUND: The Accreditation Council for Graduate Medical Education is embarking on the major task of a paradigm shift in graduate education in the direction of competency-based medical education and evaluation of outcomes. The Objective Structured Clinical Examination (OSCE), a measure of clinical competence that focuses on outcomes via observable behaviors, is gaining national recognition. OBJECTIVE: To review the pediatric literature relevant to the OSCE. METHOD: A MEDLINE search from the date of the original report of the OSCE (1975) to the present was performed. All English-language studies regarding the use of the OSCE in pediatric education published in the United States and Great Britain were reviewed. MAIN OUTCOME MEASURES: Reliability and validity of the OSCE were examined. Use of standardized pediatric patients was discussed. RESULTS: A greater number of stations and similarity between tasks at different stations increased the reliability of the OSCE. A greater number of stations increased sampling of material and content validity. Correlation between the OSCE and precertification examinations ranged between 0.59 and 0.71, with P< or =.01. Correlation between the OSCE and monthly clinical evaluations was much lower (0.39-0.57), but still statistically significant at P< or =.05. Gaps between expected and actual performance were documented. Overall, the experience of being a standardized patient was viewed as positive by children and their parents. CONCLUSIONS: With appropriate attention to design, acceptable reliability and validity can be achieved for the OSCE. Significant correlations between the OSCE and precertification examinations as well as monthly clinical evaluations were found, the former being stronger than the latter. We conclude that the combination of the OSCE, standardized board examinations, and direct observation in the clinical setting has the potential to become the "gold standard" for measuring physician competence.

Acceptance of family member presence during pediatric resuscitations in the emergency department: effects of personal experience.

OBJECTIVE: Opinions remain polarized on allowing family member presence during pediatric resuscitations (FMP). Reluctance to adopt FMP may stem from preconceived notions on this practice. This study evaluates the effect of prior experience with FMP and on its acceptance by emergency department personnel (EDP). METHODS: EDP from three different EDs were surveyed concerning FMP. Study facilities included an urban teaching community ED with routine FMP (R-ED), a suburban community ED with occasional FMP (O-ED) and an urban university pediatric ED with virtually no FMP (N-ED) during pediatric resuscitations. Survey information included hospital of practice, position in ED, years in practice, opinions on FMP and personal experience with FMP for five clinical scenarios: laceration repair (LAC), intravenous access (IV), lumbar puncture (LP), endotracheal intubation (ETI), cardiopulmonary resuscitation (CPR), and critical resuscitation (CR). Statistical analysis was through chi square and regression analysis. RESULTS: Eighty-five emergency department personnel participated in the survey, 57 (67%) nurses, 22 (25%) physicians, 4 technicians (5%), and 2 nurses aids (2%). There was a significant correlation between a favorable opinion concerning family member presence during LP, ETI, CPR and CR and the type of Emergency Department in which the individual practiced (P<0.002). Regression analysis demonstrated a similar relation between personal experience with LAC, IV, ETI, CR, and CPR and a favorable opinion on FMP during that activity (P<0.03). CONCLUSION: Opinions on FMP are strongly influenced by experience with this practice. Emergency department personnel with prior exposure to family member presence during resuscitations favor this activity. Biases by EDP lacking experience with FMP may limit its introduction into unfamiliar institutions.

The potential for errors in children with special health care needs.

Children with special health care needs (CSHCN) are at risk for suboptimal treatment when presenting for emergent care to unfamiliar health care providers. Errors in their management may stem from failure to recognize occult conditions, lack of familiarity with rare or complex medical problems, or lack of prior knowledge of baseline physical findings. An emergency information form (EIF) that contains patient-specific information on essential diagnostic and therapeutic interventions may provide a ready personal reference for the emergent care of CSHCN. Coupled with the use of medical identification jewelry and an electronic transmission system, an EIF has the potential to eliminate management errors in the care of these patients.

Lidocaine for lumbar punctures. A help not a hindrance.

OBJECTIVE: To determine whether premedication for lumbar puncture (LP) with lidocaine hinders collection of cerebrospinal fluid (CSF) through either increased number of attempts or increased incidence of traumatic punctures. DESIGN: A randomized controlled trial. SETTING: The pediatric emergency department of an innercity teaching hospital. PATIENTS: A convenience sample of 100 children, younger than 3 years, who required an LP as part of their diagnostic workup. INTERVENTION: Patients were randomized to receive either lidocaine or no local anesthetic before undergoing an LP. MAIN OUTCOME MEASURES: Comparison of the number of attempts needed to obtain CSF and the number of traumatic LPs between the lidocaine-treated and no local anesthetic groups. RESULTS: The 51 patients randomized to receive lidocaine did not differ markedly in age from the 49 patients randomized to receive no local anesthetic. Ease of obtaining CSF, as measured by number of attempts, did not differ with 59% of the patients in each group requiring 1 attempt. Defining a traumatic LP as more than 1000 x 10(6)/L red blood cells in the CSF showed notably more traumatic LPs in the lidocaine-treated group. Defining a traumatic LP as one with more than 10,000 x 10(6)/L red blood cells in the CSF showed no significant difference in the number of traumatic LPs whether or not the patient was premedicated with lidocaine. The level of experience of the physician performing the LP did not affect the outcome. CONCLUSIONS: Premedication with lidocaine for an LP does not binder the ease of obtaining CSF. The clinical relevance of a greater number of traumatic LPs in the lidocaine-treated group is questionable because this finding is negated when traumatic is defined as more than 10,000 x 10(6)/L CSF red blood cells. Based on these results, we advocate premedication with a local anesthetic when an LP is performed in the pediatric emergency department.

Subcutaneous lidocaine does not affect the success rate of intravenous access in children less than 24 months of age.

OBJECTIVE: To determine whether subcutaneous lidocaine (SQL), when used to decrease the pain of IV catheter insertion, adversely affects IV access in children < 24 months of age. METHODS: A historically controlled comparison of IV access successes with and without SQL in children < 2 years of age was performed in a 30,000-annual-visit community hospital ED. On-site data collected at the time of IV placement included: patient age, weight, hydration status, number of attempts, and location of attempts. All patients had IV attempts made by the same emergency physician. RESULTS: A total of 110 children, mean age 9.6 +/- 6.9 months, were included in the study analysis. Of the 110, 70 had an IV catheter placed with no pretreatment, while 40 had SQL pretreatment. The average number of attempts for all patients was 1.36 +/- 0.73, with 83 (75%) performed successfully in 1 attempt and 101 (91%) within 2 attempts. The mean numbers of attempts were similar for the control and SQL groups: 1.34 vs 1.40, respectively (p = 0.68), as were the proportions successful in 1 attempt (77% vs 73%; p = 0.58) and within 2 attempts (91% vs 90%; p = 0.84). CONCLUSION: SQL use prior to an IV attempt in children < 2 years of age does not impact vascular access. A secondary finding was that vascular access with and without SQL in infants and small children generally can be accomplished in 1 attempt.

Cerebrospinal fluid analysis in systemically ill children without central nervous system disease.

OBJECTIVE: Experience led us to question the applicability of standards for normal cerebrospinal fluid (CSF), originally developed in healthy children, to children with systemic illness but without central nervous system (CNS) infection. The purpose of this study was to test our hypothesis that systemically ill children, in the absence of CNS infection, have an elevated CSF white blood cell count and a greater percentage of neutrophils than accepted norms. METHODS: We enrolled 345 patients in the following diagnostic categories: infants 1 month of age or younger with possible sepsis (n = 95), patients older than 1 month of age with possible sepsis (n = 155), patients with a focus of infection in close proximity to the CNS (n = 51), and patients presenting with seizures and fevers (n = 45). Sociodemographic data and results of CSF examination were abstracted from the medical records. Statistical analysis systems were used for data processing. RESULTS: The CSF white blood cell count did not significantly differ from standards except for a lower mean count in the group presenting with seizures. The percent of CSF neutrophils was significantly greater than standards, however, for those patients older than 1 month of age with possible sepsis, those with a focus of infection in close proximity to the CNS, and those presenting with seizures. Data analysis by quantiles shows only 25% to 50% of patients, in each of the diagnostic categories, meeting the current definition of normal CSF neutrophil count. CONCLUSIONS: Our results show that a mean of at least 5% neutrophils may be present in the CSF with a diagnosis of fever without a source, a focus of infection in close proximity to the CNS, or a seizure with fever in the absence of CNS infection. These data support tailoring treatment based on clinical assessment rather than what is considered an abnormal CSF neutrophil count by current standards.

Hand-held metal detector identification of ingested foreign bodies.

The study purpose was to determine the ability of hand-held metal detectors (HHMDs) to identify the presence of ingested metallic foreign bodies (MFBs). Twenty-three children presenting to the emergency department with a complaint of MFBs ingested were enrolled. Sixteen of 23 patients had radiographically proven foreign bodies. The MFBs comprised coins (n = 11), a button battery (n = 1), a medallion (n = 1), a token (n = 1), a needle (n = 1), and a marble (leaded glass) (n = 1). The HHMD correctly detected 15 of 16 radiographically positive MFBs (93%) and correctly excluded a potential MFB in six of six radiographically negative cases. The only foreign body not detected was an ingested needle. One radiograph was equivocal. Radiographic localization of the ingested objects was as follows: esophagus, n = 4; stomach, n = 9; and intestines, n = 3. The HHMD correctly localized all detected MFBs. The HHMD had a sensitivity of 94%, a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 86%. HHMDs are effective screening devices for possible ingested MFBs. Positive studies localized to the stomach and lower gastrointestinal tract do not require confirmatory radiographic studies.

Factors influencing the choice of a residency training program. A student's perspective.

Current trends in pediatric residency training have shown that a growing number of programs have been unable to fill their available positions through the National Resident Matching Program, Evanston, Ill. This has caused a competitive climate among programs to attract medical students as potential residents. The purpose of this study was to learn what factors are important to all students in determining the rank order of the residency training programs to which they have applied. Analysis of data obtained from 600 survey respondents (40%) showed that program curriculum was most important. Factors, such as night call and benefits, took on much less importance. Differences did exist between students who applied for pediatric vs other residencies. The balance between primary and tertiary care and a university setting are examples of variables that had a greater influence on aspiring pediatricians. This information has important implications for training program directors.

Resident management of emergency department patients: is closer attending supervision needed?

STUDY OBJECTIVE: To determine the extent of supervision necessary for emergency medicine residents practicing in the emergency department. SETTING: ED of a university-affiliated tertiary care facility with an annual census of 32,000 visits. STUDY POPULATION: All ED patients presenting during study hours during a four-month period. DESIGN: A prospective study was conducted of changes made by emergency medicine attendings in the management of ED patients seen initially by second-year emergency medicine residents. Second-year emergency medicine residents presented all patients seen by them to a specified emergency medicine attending, who also interviewed and examined these patients. Initial patient care was designed by the resident and modified by the emergency medicine attending. Attending modification was recorded by the emergency medicine attending in the study log. Modifications of the residents' proposed care were designated as major (change resulted in an alteration in patient disposition, detection of unsuspected pathology, or marked revision of intended treatment); minor (change resulted in lesser modification of patient management); or no change. RESULTS: Four hundred eight patient encounters were included in the study. Sixteen patients (4%) had major modifications of their care, 134 (33%) had minor modifications, and 258 (63%) had no change. CONCLUSION: Supervision is required for all patients managed by second-year emergency medicine residents, regardless of complaints. This evaluation should include a direct patient interview and examination by the emergency medicine attending and should not be limited to a case discussion or ED record cosignature.

Pediatric EMS transport: are we treating children in a system designed for adults only?

Unlike adults, small children and infants do not require stretchers or ambulances for transport from a prehospital scene to the emergency department (ED). This study was designed to determine the importance of this difference in patient transport needs. A Macintosh Classic computer was programmed to compare the time to intubation (TTI) of a child with impending respiratory arrest treated in a standard paramedic/ambulance transport system versus that of a child treated in a system in which a patrolling police car transports the child directly to an ED. The dependent variable TTI was determined, with travel times from the scene to the ED and paramedic intubation success rates as the independent variables. Utilizing this model, police transports demonstrate shorter TTIs for brief scene-to-ED travel times or limited paramedic success rates, while paramedic intubations produced shorter TTIs for long scene-to-ED transports. These results suggest that nonambulance transport of pediatric patients be considered in the development of urban or suburban pediatric Emergency Medical Services.

Current trends in pediatric residency training.

A spreading gap has developed between available pediatric level 1 positions and those filled through the National Resident Matching Program. To define which variables enhance a program's ability to match, we surveyed program directors of all categorical pediatric training programs. An 82% response rate showed that ability to match was positively associated with larger program size and offering of shared residency positions. A negative association was found between many benefits and ability to match. The call schedule and number of call-free elective months had no measurable effect. Factors that we were unable to investigate, such as geographic location and academic reputation, may also play a role. Our results emphasize the irrelevance of enhancing benefits as a way of making programs competitive. Our energies need to be directed at attracting junior medical students to a career in pediatrics rather than competing for fourth-year students applying to pediatric programs.

Initial management of adolescent overdoses.

A retrospective study of pediatric patients presenting to a community hospital emergency department with acute intentional toxidromes was conducted. The characteristics of these patients and their initial medical management were reviewed. Forty-six patients were included in this study with 35 recreational overdoses and 11 suicide attempts or gestures. The mean age of these patients was 15.8 (range 10 to 18 years). The most commonly abused substance was ethanol, followed in frequency by benzodiazepines and barbiturates. Initial management centered on active airway management, gastrointestinal decontamination, and extended observation. Ten patients were intubated, lavaged, extubated, and subsequently discharged from the emergency department. Only one patient required hospital admission. The value of toxicologic screens, emergency department endotracheal intubations, gastric lavage, and charcoal/cathartic therapy is discussed.
