An international assessment of a web-based diagnostic tool in critically ill children.

Improving diagnostic accuracy is essential. The extent of diagnostic uncertainty at patient admission is not well described in critically ill children. Therefore, we studied the extent that pediatric trainee diagnostic performance could be improved with the aid of a computerized diagnostic tool. Data regarding patient admissions to five Pediatric Intensive Care Units were collected. Information included patients' clinical details, admitting team's diagnostic workup and discharge diagnosis. An attending physician assessed each case independently and suggested additional diagnostic possibilities. Diagnostic accuracy was calculated using the discharge diagnosis as the gold standard. 206 out of 927 patients (22.2%) admitted to the PICUs did not have an established diagnosis at admission. The trainee teams considered a median of three diagnoses in their workup (IQR 3-5) and made an accurate diagnosis in 89.4% cases (95% CI 84.6%-94.2%). Diagnostic accuracy improved to 92.5% with use of the diagnostic tool alone, and to 95% with the addition of attending physicians' diagnostic suggestions. We conclude that a modest proportion of admissions to these PICUs were characterized by diagnostic uncertainty during initial assessment. Although there was a relatively high accuracy rate of initial assessment in our clinical setting, it was further improved by both the diagnostic tool and the physicians' diagnostic suggestions. It is plausible that the tool's utility would be even greater in clinical settings with less expertise in critical illness assessment, such as community hospitals, or emergency departments of non-training institutions. The role of diagnostic aids in the care of critically ill children merits further study.further study.

Assessment of parental presence during bedside pediatric intensive care unit rounds: effect on duration, teaching, and privacy.

OBJECTIVE: There is a paucity of literature evaluating the effects of family member presence during bedside medical rounds in the pediatric intensive care unit. We hypothesized that, when compared with rounds without family members, parental presence during morning medical rounds would increase time spent on rounds, decrease medical team teaching/education, increase staff dissatisfaction, create more stress in family members, and violate patient privacy in our open unit. DESIGN: Prospective, blinded, observational study. SETTING: Academic pediatric intensive care unit with 12 beds. PARTICIPANTS: A total of 105 admissions were studied, 81 family members completed a survey, and 187 medical team staff surveys were completed. INTERVENTIONS: Investigators documented parental presence and time allocated for presentation, teaching, and answering questions. Surveys related to perception of goals, teaching, and privacy of rounds were distributed to participants. MEASUREMENTS: Time spent on rounds, time spent teaching on rounds, and medical staff and family perception of the effects of parental presence on rounds. RESULTS: There was no significant difference between time spent on rounds in the presence or absence of family members (p = NS). There is no significant difference between the time spent teaching by the attending physician in the presence or absence of family members (p = NS). Overall, parents reported that the medical team spent an appropriate amount of time discussing their child and were not upset by this discussion. Parents did not perceive that their own or their child's privacy was violated during rounds. The majority of medical team members reported that the presence of family on rounds was beneficial. CONCLUSIONS: Parental presence on rounds does not seem to interfere with the educational and communication process. Parents report satisfaction with participation in rounds, and privacy violations do not seem to be a concern from their perspective.

The use of a daily goals sheet to improve communication in the paediatric intensive care unit.

OBJECTIVE: To assess the impact of the implementation of a daily goals sheet upon nursing perception of communication in an academic, tertiary care paediatric intensive care unit (PICU). DESIGN: Prospective, longitudinal, before-and-after intervention surveys. SETTING: University affiliated 12-bed PICU. SUBJECTS: Bedside nurses. INTERVENTIONS: A questionnaire was administered to PICU nurses addressing their perception of communication. Following this questionnaire, the use of a daily goals sheet was instituted. A second questionnaire was administered one year later. Mann-Whitney Rank Sum Test was used to compare differences of the graded outcome variables. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the perception of communication taken from a nursing perspective. Eighty-five percent of nurses felt the daily goals sheet led to improved communication between physicians and nurses in the PICU. All questions related to communication demonstrated a positive influence of the goals sheet, with the perception of the PICU staff working as a team reaching statistical significance (p=0.05). The perception of the care of one surgical service being attending physician directed also significantly improved after the institution of the goals sheet (p=0.04). CONCLUSION: The institution of a daily goals sheet led to an improvement in nursing perception of communication. Future studies are required to determine if this change in process has a demonstrable effect on health care outcomes of critically ill children, or whether this tool can have the same beneficial effects in other academic and non-academic PICUs.

A randomized controlled trial comparing three different techniques of nasojejunal feeding tube placement in critically ill children.

BACKGROUND: The goal of this study was to compare 3 different techniques used to place nasojejunal (NJ) feeding tubes in the critically ill or injured pediatric patients. This was a randomized, prospective trial in a university-affiliated 12-bed pediatric intensive care unit. Patients were critically ill children requiring placement of an NJ feeding tube. Patient age, weight, medications, use of mechanical ventilation, and patient tolerance were recorded. An abdominal radiograph obtained immediately after the placement determined correct placement. The final placement was recorded, as was the number of placement attempts. METHODS: Patients were randomized to 1 of 3 groups: standard technique, standard technique facilitated with gastric insufflation, and standard technique facilitated with the use of preinsertion erythromycin. To ensure equal distribution, all patients were stratified by weight (<10 kg vs > or =10 kg) before randomization. All NJ tubes were placed by one of the investigators. If unsuccessful, a second attempt by the same investigator was allowed. Successful placement of the NJ tube was defined by confirmation of the tip of the tube in the first part of the duodenum or beyond by a pediatric radiologist blinded to the treatment groups. RESULTS: Seventy-five pediatric patients were enrolled in the study; 94.6% (71/75) of tubes were passed successfully into the small bowel on the first or second attempt. Evaluation of the data revealed no significant association with a specific technique and successful placement (p = .1999). CONCLUSIONS: When placed by a core group of experienced operators, the majority of NJ feeding tubes can be placed in critically ill or injured children on the first or second attempt, regardless of the technique used.

Prospective assessment of guidelines for determining appropriate depth of endotracheal tube placement in children.

OBJECTIVE: To determine whether multiplying the internal diameter of the endotracheal tube (ETT) by 3 (3x ETT size) is a reliable method for determining correct depth of oral ETT placement in the pediatric population. DESIGN: Prospective, observational. SETTING: University-affiliated, 12-bed pediatric intensive care unit. PATIENTS: Orally intubated pediatric intensive care unit patients of < or =12 yrs of age. INTERVENTIONS: Demographics, ETT size, and depth of ETT placement measured from the lip were obtained. Correct placement, defined as the tip of the ETT below the thoracic inlet and > or =0.5 cm above the carina, was determined by chest radiograph. MEASUREMENTS AND MAIN RESULTS: Suggested ETT size based on the Pediatric Advanced Life Support (PALS) age-based formula and the Broselow tape-length-based guidelines were determined. A total of 174 of 226 ETTs (77%) were correctly positioned. If practitioners utilized the 3x ETT size for the actual tubes chosen, 170 of 226 (75%) would have been accurately placed. More accurate were the 3x PALS-based ETT size (81%) and 3x Broselow-suggested ETT size (85%). The use of the Broselow ETTs to determine the depth would have led to a significantly improved ETT position (p = .009) compared with the actual ETT. CONCLUSION: The commonly used formula of 3x tube size for ETT depth in children results in 15-25% malpositioned tubes. Practitioners can improve the reliability of this formula by utilizing the recommended ETT size as suggested by the Broselow tape. A more reliable method is necessary to avoid ETT malposition.
