Pediatric intensive care units have contributed considerably to the management of children with severe diseases and life-threatening conditions. The use of mechanical ventilation, invasive monitoring, and indwelling catheters increase the risk for nosocomial infection. Improving infection control practices and surveillance can significantly reduce the incidence of nosocomial infections.
Pediatric intensive care is a collaborative practice of dedicated personnel, advanced technology and a diverse group of support services. Unit design must focus on current patient needs while envisioning the technological and clinical needs of the future. With insight and a cooperative effort, your design team can effectively transform ideas into a unit committed to the care of critically ill children.
Temperature measurement is a commonly used assessment parameter when caring for the critically ill child. Interpreting the temperature measurement mode and what constitutes clinically significant thermal instability are poorly defined. Thus, decisions made regarding patient management based on temperature measurement can be challenging for caregivers. Infants and children have unique physioanatomic considerations that impact maintaining thermoregulation. Numerous routes for taking temperature measurements are described including the oral, axillary, tympanic (aural), rectal, skin, urinary bladder, pulmonary artery, esophageal, nasopharyngeal, supralingual (pacifier), and temporal-artery. Numerous studies on temperature measurement have been conducted on children of various ages using a variety of thermometers and routes in both the inpatient and outpatient setting. Although there are limited studies reported on the critically ill child, research data pertinent to the critically ill child from subjects in the neonatal intensive care unit, pediatric intensive care unit, operating room, and inpatient units are summarized.
These guidelines were developed to provide a reference for preparing policies on admission and discharge for pediatric intensive care units (PICUs). They represent a consensus opinion of physicians, nurses, and allied health care professionals. By using this document as a framework for developing multidisciplinary admission and discharge policies, utilization of pediatric intensive care units can be optimized and patients can receive the level of care appropriate for their condition.
BACKGROUND: Institutional protocol designates the adult trauma service as the primary manager of all adolescent traumas (age 14-18 years) unless admission to the pediatric intensive care unit (PICU) occurs. In the PICU, primary care becomes the responsibility of the pediatric intensivist, with trauma service as a consultant. The purpose of this study was to identify differences in the management of adolescent trauma between the pediatric intensivist in the PICU, and the adult trauma team in the surgical intensive care unit (SICU). METHODS: From January 1993 to January 1998, the medical records of all adolescent trauma patients requiring intensive care unit (ICU) management were reviewed. Depending on bed availability, patients younger than 16 were admitted to the PICU, and those 16 or older to the SICU. Demographic data obtained were age, sex, race, mechanism of injury, length of stay (LOS), ICU length of stay, days on mechanical ventilation, intubation, tracheotomy, intracranial pressure monitor, and Swan-Ganz catheter placement. Home discharge, rehabilitation placement, and death were recorded. Morbidity was measured using Injury Severity Score methodology, Pediatric Trauma Score, and Pediatric Risk of Mortality. RESULTS: One hundred nine completed records were reviewed (SICU, n = 58; PICU, n = 51). There was no statistical difference in sex, race, mechanism of injury, ICU LOS, tracheotomy, and intracranial pressure monitor placements. There was no difference in morbidity, as measured by Injury Severity Score, Pediatric Trauma Score, and Pediatric Risk of Mortality score or in outcome measurements (death, rehabilitation placement). SICU patients were older (SICU, 16.9 +/- 1.0 years; PICU, 15.4 +/- 1.0 years; p < or = 0.1 Mann-Whitney U test), more likely to be intubated (SICU, n = 42; PICU, n = 24; p < or = 0.05 Fisher's exact test), more likely to have pulmonary artery catheter placement (SICU, n = 7; PICU, n = 0), and had longer LOS (SICU, 12.2 +/- 10.6; PICU, 9.8 +/- 14.1; p < or = 0.03 Mann-Whitney U test). CONCLUSION: Adolescent trauma patients admitted to the PICU were less likely to be intubated or have a Swan-Ganz catheter placed. They had decreased LOS and days of mechanical ventilation. There was no difference in outcome measurements.
BACKGROUND: Pediatric intensive care units have developed as treatment areas with a concentration of specialized equipment and personnel. Critically ill children often need to be moved to and from these critical care areas for diagnostic or therapeutic procedures. Such transport may pose additional risk to the critically ill patient. PATIENTS AND METHODS: In order to assess the problems encountered in our transport process, a prospective study was performed. A questionnaire was undertaken to evaluate the transport of critically ill children hospitalized in the Pediatric Intensive Care Unit of the Hospital Universitario Puerta del Mar from Cádiz over an eleven month period. RESULTS: Two hundred children transported were evaluated. Forty-seven (23.5%) were interhospital transported patients and one hundred fifty-three (76.5%) were intrahospital transported patients. The most common type of intrahospital transport involves transfers between the operating room and the intensive care unit (73 patients, 36.5%). Deterioration in respiratory, cardiovascular and other physiological systems was registered in twenty-two patients (11%). One hundred four equipment-related mishaps were noted in eighty-six patients (43%) during the transport process. Dislodgement of intravenous catheters, loss of oxygen supply, endotracheal tube problems and equipment malfunction were the most common mishaps noted. CONCLUSIONS: Our results would suggest that more training regarding the transport of the critically ill child are needed in our area.
The pediatric intensive care unit (PICU) hospitalization of a child is stressful for parents. Helping parents to decrease their stress is warranted so that they can function in the vital role that is therapeutic to them and their critically ill child. Many parent-supportive nursing interventions have been recommended but none has been tested in the clinical setting. A quasi-experimental design was used to study the effects of the nursing mutual participation model of care (NMPMC) on the perceived environmental stress of parents in the PICU. Thirty-three parents, experiencing the PICU for the first time, participated in the study. Sequential sampling divided the participants into two groups, control and experimental. The experimental group participated in the NMPMC, designed to be supportive to and guided by the perceived individual needs of each parent. The dependent measure was the Parental Stressor Scale: Pediatric Intensive Care Unit administered within 24 to 48 hours of PICU admission, every 48 hours thereafter, and 24 hours after PICU discharge. The results indicate that the NMPMC is helpful in alleviating parental stress, specifically the stress related to interruption in the parent-child relationship, in the PICU setting.

CONTEXT: Pediatric intensive care units (PICUs) have expanded nationally, yet few studies have examined the potential impact of regionalization and no study has demonstrated whether a relationship between patient volume and outcome exists in these units. Documentation of an inverse relationship between volume and outcome has important implications for regionalization of care. OBJECTIVES: This study examines relationships between the volume of patients and other unit characteristics on patient outcomes in PICUs. Specifically, we investigate whether an increase in patient volume improves mortality risk and reduces length of stay. DESIGN AND SETTING: A prospective multicenter cohort design was used with 16 PICUs. All of the units participated in the Pediatric Critical Care Study Group. Participants. Data were collected on 11 106 consecutive admissions to the 16 units over a 12-month period beginning in January 1993. MAIN OUTCOME MEASURES: Risk-adjusted mortality and length of stay were examined in multivariate analyses. The multivariate models used the Pediatric Risk of Mortality score and other clinical measures as independent variables to risk-adjust for illness severity and case-mix differences. RESULTS: The average patient volume across the 16 PICUs was 863 with a standard deviation of 341. We found significant effects of patient volume on both risk-adjusted mortality and patient length of stay. A 100-patient increase in PICU volume decreased risk-adjusted mortality (adjusted odds ratio:.95; 95% confidence interval:.91-.99), and reduced length of stay (incident rate ratio:.98; 95% confidence interval:.975-.985). Other PICU characteristics, such as fellowship training program, university hospital affiliation, number of PICU beds, and children's hospital affiliation, had no effect on risk-adjusted mortality or patient length of stay. CONCLUSIONS: The volume of patients in PICUs is inversely related to risk-adjusted mortality and patient length of stay. A further understanding of this relationship is needed to develop effective regionalization and referral policies for critically ill children.
Pediatric neuromuscular diseases such as Duchenne muscular dystrophy and spinal muscular atrophy cause pulmonary compromise. In severely affected patients, upper respiratory tract infections exacerbate lower respiratory tract secretion retention, with the potential for pneumonia, pulmonary atelectasis, and respiratory failure. In the pediatric intensive care unit, effective treatment includes noninvasive positive pressure ventilation and manual and mechanical mucus clearance techniques. A practical approach to commonly encountered respiratory complications in pediatric neuromuscular diseases is presented in this review.
In a pediatric intensive care unit we conducted a 1-year prospective study of 454 patients to determine whether wearing a gown decreased the overall nosocomial infection rate, incidence of intravascular catheter colonization, breaks in handwashing technique, and traffic. The overall infection rate was 26 (13%) of 198 admissions during the gown-wearing periods v 23 (9%) of 256 admissions for the periods when gowns were not worn (P less than .25). Of 348 intravascular catheter tips cultured 16 (4.6%) were colonized during gown-wearing periods compared with 21 (6.3%) of 330 when no gowns were worn (P less than .25). Of 78 patient contacts 54 (69%) were followed by no handwashing during gown-wearing periods and 59 (70%) of 84 contacts were followed by no handwashing during periods when no gowns were worn. The mean occurrence of visits per patient per hour and total visits per hour differed between gown-wearing and no-gown-wearing periods by analysis of variance, P less than .01 and P less than .005, respectively. Although traffic was decreased during periods of gown use, overgowns are an expensive, ineffective method of decreasing nosocomial infection rates, vascular catheter colonization rates, and breaks in handwashing technique.
The pediatric intensive care unit (PICU) hospitalization of a child is stressful for parents. Helping parents to decrease their stress is warranted so that they can function in a vital role that is therapeutic to them and their critically ill child. Although many interventions have been recommended to help parents decrease their stress, only the Nursing Mutual Participation Model of Care (NMPMC) has been tested in the clinical setting. This article reports a study that expands on Curley's original work by investigating the effects of the NMPMC on parental stress when implemented by PICU staff nurses. Fifty-six parents participated in the study, which used a quasi-experimental design. Sequential sampling placed the first 31 subjects into the control group and the next 25 subjects in the experimental group. The experimental group received care from staff nurses instructed in the NMPMC. The dependent measure was the Parental Stressor Scale:Pediatric Intensive Care Unit (PSS:PICU) administered within 24 to 48 hours of PICU admission, every 48 hours thereafter, and 24 hours after PICU discharge. The results indicated that parents in the experimental group perceived less stress than the control group, specifically the stress related to alterations in parental role in the PICU setting. Implications for nursing care are discussed.
OBJECTIVE: For pediatric intensive care unit (ICU) survivors, to determine the proportion of hospital stay and estimated hospital costs accounted for by post-ICU care. DESIGN: Prospective study. SETTING: University teaching hospital. PATIENTS: Pediatric patients who survive an ICU admission. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Estimated relative daily costs were assumed as follows: ICU, with ventilator/ICU, not on ventilator/intermediate care unit/general pediatric hospital day, at 2:1:0.7:0.3, respectively. Estimated costs were expressed in arbitrary units as (number of days at each level of care) x (relative cost per day). The ICU phase was defined as the patient's first ICU admission only, and the post-ICU phase included intermediate care unit and general pediatric hospital days, as well as ICU readmission during the same hospitalization. Pre-ICU hospital activity was excluded from analysis. For 341 ICU survivors, post-ICU days (median, 4 days per patient) accounted for 62% of the total hospital stay. Post-ICU care accounted for one third of the total estimated hospital costs for ICU survivors. Patients with longer post-ICU stays could not be reliably identified at the time of ICU discharge according to their ICU length of stay, duration of mechanical ventilation in the ICU, age, ICU day 1 mortality probability, or diagnostic group (p>.05). CONCLUSIONS: Post-ICU care accounts for a substantial proportion of hospital stay and estimated costs for ICU survivors. These observations suggest that developing strategies to optimize hospital utilization at the time of ICU discharge may be important for controlling costs of recovery from critical illness.
OBJECTIVE: Assessment of pediatric intensive care unit (PICU) efficiency with a length of stay prediction model and validation of this assessment by an efficiency measure based on daily use of intensive care unit-specific therapies. DESIGN: Inception cohort study of data acquired between 1989 and 1994. SETTING: Thirty-two PICUs, 16 selected randomly and 16 volunteering. SUBJECTS: Consecutive admissions of 10,658 patients (466 deaths) who stayed at least 2 hours and up to 12 days in the PICU. MEASUREMENTS: Length of stay and its prediction from a model with admission day data (PRISM III-24, diagnostic factors, mechanical ventilation). For validation 11 PICUs recorded each patient's "efficient" days, that is, days when at least one PICU-specific therapy was given. PICU efficiency was computed as either the ratio of the observed efficient days or the days accounted for by the predictor variables to the total care days, and the agreement was assessed by Spearman's rank correlation analysis. RESULTS: The total care days provided by each PICU (n = 32) were well predicted by the length of stay model (r = 0.946). The agreement in 11 validation PICUs between therapy-based efficiency (range 0.30 to 0.67) and predictor-based efficiency (range 0.31 to 0.63) was excellent (rank correlation r = 0.936, p < 0.0001). CONCLUSION: PICU efficiency comparisons with either method are nearly equivalent. Predictor-based efficiency has the advantage that it can be computed from admission day data only.
Personnel of a pediatric intensive care unit claimed health problems due to air draughts. Mucous membrane symptoms such as burning eyes, an increased number of colds as well as headaches and stiff necks were the most frequent complaints. According to our indoor climate analysis high turbulence intensities were the main cause for thermal discomfort (Tumax = 88%, Tumin = 50%, median = 58% at measuring position Nr. 7). The percentage of people dissatisfied due to draught (PD value) were for example PDmax = 31%, PDmin = 6.7%, median = 16% at measuring position Nr. 7. In addition the humidification device of the HVAC system was not run continuously resulting in relative humidities below existing standards (51% r.h. in summer and 28% r.h. during the heating period).
Patients in a pediatric intensive care unit were placed with patients in an adult surgical intensive care unit (SICU) in a large, 12-bed room previously occupied exclusively by the adult patients. The occurrence of multiply resistant Staphylococcus aureus (MRSA) in pediatric patients increased from zero cases during the preceding 12 months to seven cases (p less than 0.001) for the 95 days that the units were combined. The rate of acquisition of MRSA by the patients in the SICU remained unchanged. Pediatric patients who acquired MRSA had longer lengths of stay (p less than 0.001) and underwent more surgical (p less than 0.01) and invasive procedures than did pediatric patients who did not acquire MRSA. Removal of the pediatric patients to their own unit returned their rate of MRSA acquisition to the previous low level.
Pediatric intensive care units use sophisticated medical technology and are staffed by deeply committed nurses who are subjected to significant psychological stress. This stress varies with the type of patient and influences the style and quality of care. With this respect, children and adolescents admitted after a suicidal attempt are considered catalysts. However, there have been no systematic studies of how pediatric intensive care nurses respond emotionally to their interactions with these patients. This epidemiological study conducted in five Parisian Teaching Hospital pediatric intensive care units used a specially designed questionnaire to evaluate nurses' responses on the basis of style of care. Children under 16 years of age admitted after attempted suicide were studied comparatively with same age children admitted for status asthmaticus or encephalopathy with seizures. Results highlighted the differences in nurses' psychological responses to these situations and their difficulties in interacting with patients. This study provides strict methodological guidelines for investigating an issue often discussed emotionally or on the basis of anecdotal data.
These guidelines were developed to provide a reference for preparing policies on admission to and discharge from pediatric intensive care units. They represent a consensus opinion of physicians, nurses, and allied health care professionals. By using this document as a framework for developing multidisciplinary admission and discharge policies, use of pediatric intensive care units can be optimized and patients can receive the level of care appropriate for their condition.
