Challenges in setting up pediatric and neonatal intensive care units in a resource-limited country

In collaboration with a host country and international medical volunteers, a PICU and an NICU were conceptualized and realized in the developing country of Nepal. We present here the challenges that were encountered during and after the establishment of these units. The decision to develop an ICU with reasonable goals in a developing country has to be made with careful assessments of need of that patient population and ethical principles guiding appropriate use of limited resources. Considerations during unit design include space allocation, limited supply of electricity, oxygen source, and clean-water availability. Budgetary challenges might place overall sustainability at stake, which can also lead to attrition of trained manpower and affect the quality of care. Those working in the PICU in resource-poor nations perpetually face the challenges of lack of expert support (subspecialists), diagnostic facilities (laboratory and radiology), and appropriate medications and equipment. Increasing transfer of severely ill patients from other health facilities can lead to space constraints, and lack of appropriate transportation for these critically ill patients increases the severity of illness, which leads to increased mortality rates. The staff in these units must make difficult decisions on effective triage of admissions to the units on the basis of individual cases, futility of care, availability of resources, and financial ability of the family.     

Ventilator-associated pneumonia in a paediatric intensive care unit in a developing country with high HIV prevalence

Aim:   To obtain preliminary prevalence, aetiological and outcome data on South African paediatric patients with ventilator-associated pneumonia (VAP).
Methods:   Non-bronchoscopic bronchoalveolar lavage (BAL) specimens taken between January 2004 and September 2005 were prospectively recorded and related clinical data were retrospectively reviewed. VAP was defined as a new isolate on BAL and a modified Clinical Pulmonary Infection Score ≥5.
Results:   A total of 230 patients aged 3.9 (2.2–9.1) months (median interquartile range (IQR) ) underwent 309 BALs during 244 paediatric intensive care unit (PICU) admissions. Most patients (84%) were admitted with acute infectious diseases, with a 70% incidence of comorbidity. Thirty-three patients (14.3%) were HIV-exposed but uninfected and 58 (25.2%) were HIV-infected.
Of 172 BALs taken ≥48 h after intubation, 63 specimens from 55 patients fulfilled VAP criteria. Acinetobacter baumannii was the most common VAP pathogen, followed by Klebsiella pneumoniae , viruses, yeasts and Staphylococcus aureus.
Patients who developed VAP had a higher proportion of comorbid conditions (76% vs. 55%, P = 0.01) and reintubations (39% vs. 12%, P < 0.0001) when compared with non-VAP patients. Median (IQR) length of PICU stay was 12.5 (5–21) days versus 8 (5–14) days ( P = 0.03); and the risk adjusted PICU mortality was 1.38 versus 0.79 ( P = 0.002) in VAP versus non-VAP patients, respectively.
Conclusions:   VAP is associated with significant morbidity and mortality and may relate to the high incidence of comorbid conditions in this population. Primary VAP pathogens differ from developed countries.     

Acinetobacter meningitis: acquired infection in a neonatal intensive care unit

A cluster of 4 cases of meningitis due to Acinetobacter calcoaceticus var anitratus occurred during a 5-day period in a neonatal intensive care unit. Three of the infants were preterm and all had a history of other medical problems. Initiation of intravenous therapy with carbenicillin was accompanied by clinical recovery and a bacteriological cure. Intensive bacteriological investigation failed to show a common source for the infections.     

Sedoanalgesia in paediatric intensive care: a survey of 19 Italian units

Aim: To analyse the methods used to manage and monitor sedoanalgesia at Italian paediatric intensive care units (ICUs). Methods: Data were collected by administering a questionnaire that aimed to investigate whether ICUs adopted a validated protocol to manage sedoanalgesia. Results: The results revealed that a majority of the ICUs adopt a protocol for dealing with sedation and analgesia, but this protocol is implemented with difficulty or not at all in routine clinical practice. The most often used pharmacological combination, is midazolam and fentanyl. Several weaknesses remain in terms of the methods used to assess sedoanalgesia, which are generally not standardized, but rather based on recording the patient’s physiological parameters. Conclusion: Sedation and analgesia are priority issues in the management of critically ill children. None of the numerous drugs available is ideal and the protocols currently used in clinical practice involve the combined use of different drugs. There is currently no shared and validated approach as to which is the most effective and safest sedoanalgesic regimen in critically ill children.

Pneumomediastinum in the neonatal and paediatric intensive care unit

The incidence, aetiology and pathophysiology of pneumomediastinum (PM), an uncommon and potentially serious disease in neonates and children, were evaluated. A retrospective chart review of all patients diagnosed with PM who were hospitalised in the intensive care unit of the University Children’s Hospital Zürich, Switzerland, from 2000 to 2006, was preformed. We analysed the incidence, severity and causes of PM and investigated the possible differences between neonatal and non-neonatal cases. Seven children and nine neonates were identified with PM. All patients had a good outcome. Six cases of PM in the group of children older than 4 weeks were deemed to be caused by trauma, infection and sports, whereas one case was idiopathic. All nine neonatal cases presented with symptoms of respiratory distress. We were able to attribute four cases of neonatal PM to pulmonary infection, immature lungs and ventilatory support. Five neonatal cases remained unexplained after careful review of the hospital records. In conclusion, PM in children and neonates has a good prognosis. Mostly, it is associated with extrapulmonary air at other sites. It is diagnosed by chest X-ray alone. We identified mechanical events leading to the airway rupture in most children >4 weeks of life, whereas we were unable to identify a cause in half of the neonates studied (idiopathic PM).     

Surveillance of infection in neonatal intensive care units

Monitoring infection rates is increasingly regarded as an important contributor to safe and high quality health care, especially in intensive care settings. Early-onset neonatal sepsis rates are an important indicator of ante- and intra-partum care, especially as medicalisation of obstetric practice increases. However, surveillance of late-onset neonatal sepsis is required to monitor the quality of Neonatal Intensive Care Unit (NICU)-related care. Infection surveillance on NICUs presents a number of unique challenges, including defining infections, the preponderance of coagulase-negative staphylococci as both pathogens and commensals, and allowing for the influence of important risk factors. Ideally an infection surveillance programme should permit benchmarking of infection rates, and multi-centre programmes have been reported to decrease the incidence of healthcare-associated infections on NICUs. However, further research is required to identify the most clinically- and cost-effective means of surveying NICU-acquired infections before a national programme can be implemented. Until then, considerable value can be obtained from local infection surveillance.     

Management of outbreaks in neonatal intensive care units

Outbreaks in neonatal intensive care units (NICUs) have disastrous consequences for neonates and raise enormous concerns in staff, altering usual practice patterns of the NICU. Our objective was to perform a systematic analysis for gaining insights into the control and prevention of NICUs outbreaks. Epidemiology, risk factors and outcomes are reviewed.     

Outbreaks of human coronavirus in a paediatric and neonatal intensive care unit

Human coronavirus 229E (HCoV) has been recently recognized as a potential agent of nosocomial viral respiratory infections (NRVI) in high-risk infants. We have confirmed this as fact through the study of a 1-year period of HCoV outbreaks occurring during a prospective survey of NRVI in a paediatric and neonatal intensive care unit (PNICU) using new molecular techniques for HCoV detection. Nasal samples obtained at admission and weekly thereafter for all hospitalised children, as well as monthly nasal samples from staff, were analysed using immunofluorescence for respiratory syncitial virus (RSV), influenza viruses A and B, paramyxoviruses 1, 2, 3 and adenoviruses. RT-PCR was used for HCoV detection. During the year 1998, 43 HCoV-related NRVI were detected in 152 neonates (incidence 28.3%), and 7 HCoV-related NRVI were found in 92 children (incidence 7.6%). Three HCoV-related outbreaks were observed (February, August and December), associated with a high prevalence of HCoV infection in the staff. During the August outbreak, 50% to 78% of hospitalised neonates and children were infected. Seventy-five percent of hospitalised preterm neonates with a gestational age less than 32 weeks and 52.4% of staff members were infected. Risk factors for NRVI in neonates were birth weight, gestational age, ventilation, oxygenation and hospitalisation length. Ninety-two percent of infected preterm neonates were symptomatic, mainly with bradycardia and respiratory worsening. These data provide additional evidence for a possibly significant role of HCoV in NRVI in a PNICU. The role of staff or hospitalised children in spreading HCoV is hypothesised.     

Candidemia in neonatal intensive care units: Barcelona, Spain

BACKGROUND: Candida spp. are increasingly important hospital-acquired pathogens in neonatal intensive care units (NICU) and cause considerable mortality in preterm infants. Most studies have been limited to a single institution. The aim of this study was to determine the epidemiology of candidemia in all Barcelona NICUs. METHODS: We conducted prospective population-based surveillance for candidemia in Barcelona, Spain, during 2002-2003. This report focuses on the results from 5 participating hospitals with NICUs. RESULTS: We detected 24 cases, resulting in an annual incidence of 32.6 cases per 100,000 live births and 1.1 cases per 100 NICU discharges. Median gestational age was 27.5 weeks (range, 24-40.5), and there were 21 cases among very low birth weight infants. Among the 20 (83%) cases evaluated for the presence of end organ infection, endophthalmitis occurred in 2 cases, and endocarditis, meningitis and peritonitis occurred in 1 case each. Candida parapsilosis was the most frequent species isolated (67%). All isolates were fluconazole-susceptible. Crude mortality was 21%. CONCLUSIONS: The preponderance of C. parapsilosis candidemias observed in Barcelona NICUs is similar to reports from the literature. Morbidity and mortality associated with neonatal candidemia remain high.     

Calibration of the paediatric index of mortality in UK paediatric intensive care units

AIM—To test a paediatric intensive care mortality prediction model for UK use.
METHOD—Prospective collection of data from consecutive admissions to five UK paediatric intensive care units (PICUs), representing a broad cross section of paediatric intensive care activity. A total of 7253 admissions were analysed using tests of the discrimination and calibration of the logistic regression equation.
RESULTS—The model discriminated and calibrated well. The area under the ROC plot was 0.84 (95% CI 0.819 to 0.853). The standardised mortality ratio was 0.87 (95% CI 0.81 to 0.94). There was remarkable concordance in the performance of the paediatric index of mortality (PIM) within each PICU, and in the performance of the PICUs as assessed by PIM. Variation in the proportion of admissions that were ventilated or transported from another hospital did not affect the results.
CONCLUSION—We recommend that UK PICUs use PIM for their routine audit needs. PIM is not affected by the standard of therapy after admission to PICU, the information needed to calculate PIM is easy to collect, and the model is free.

     

Digital scrapbooking as a standard of care in neonatal intensive care units: initial experience

In this article, we describe a digital photo scrapbooking project as a standard of care for the parents of infants admitted in a neonatal intensive care unit (NICU). Photographs were taken from birth until discharge or expiry at special moments during the infant's hospitalization and used to create a digital scrapbook with daily notes by the parents. The scrapbook and original photos were provided on a CD at discharge or at expiry. Parents and their families unanimously appreciated the photos and the opportunity to record their thoughts, and considered the CDs as a lifetime treasure. Digital photo journaling could be implemented as a standard of care at other institutions with a commitment from the nursing and ancillary staff of the NICU and labor and delivery department, with possible support from volunteers.
