Pediatric Index of Mortality and PIM2 Scores Have Good Calibration in a Large Cohort of Children from a Developing Country

Objective. Our objective was to validate the Pediatric Index of Mortality (PIM) and PIM2 scores in a large cohort of children from a developing country. Design. Prospective observational study. Setting. Pediatric intensive care unit of a tertiary care teaching hospital. Patients. All children aged <18 years admitted between June 2011 and July 2013. Measurements and Main Results. We evaluated the discriminative ability and calibration as measured by the area under the receiver operating characteristic (ROC) curves, the HosmerLemeshow goodness-of-fit (GOF), and standardized mortality ratio (SMR), respectively. Of the 819 children enrolled, 232 (28%) died. The median (IQR) age of the study subjects was 4 years (0.8, 10). The major reasons for ICU admission as well as mortality were sepsis/severe sepsis. The area under ROC curves for PIM and PIM2 was 0.72 (95% CI: 0.67-0.75) and 0.74 (95% CI: 0.70-0.78), respectively. The goodness-of-fit test showed a good calibration across deciles of risk for the two scores with values being >0.05. The SMR (95% CI) was 0.99 (0.85-1.15) and 1 (0.85-1.16) for PIM and PIM2, respectively. The calibration across different age and diagnostic subgroups was also good. Conclusion. PIM and PIM2 scores had good calibration in our setup

Antenatal corticosteroids for women at risk of imminent preterm birth in low-resource countries: the case for equipoise and the need for efficacy trials

The scientific basis for antenatal corticosteroids (ACS) for women at risk of preterm birth has rapidly changed in recent years. Two landmark trials—the Antenatal Corticosteroid Trial and the Antenatal Late Preterm Steroids Trial—have challenged the long-held assumptions on the comparative health benefits and harms regarding the use of ACS for preterm birth across all levels of care and contexts, including resource-limited settings. Researchers, clinicians, programme managers, policymakers and donors working in low-income and middle-income countries now face challenging questions of whether, where and how ACS can be used to optimise outcomes for both women and preterm newborns. In this article, we briefly present an appraisal of the current evidence around ACS, how these findings informed WHO’s current recommendations on ACS use, and the knowledge gaps that have emerged in the light of new trial evidence. Critical considerations in the generalisability of the available evidence demonstrate that a true state of clinical equipoise exists for this treatment option in low-resource settings. An expert group convened by WHO concluded that there is a clear need for more efficacy trials of ACS in these settings to inform clinical practice

Knowledge and Skill Retention of In-Service versus Preservice Nursing Professionals following an Informal Training Program in Pediatric Cardiopulmonary Resuscitation: A Repeated-Measures Quasiexperimental Study

Our objective was to compare the impact of a training program in pediatric cardiopulmonary resuscitation (CPR) on the knowledge and skills of in-service and preservice nurses at prespecified time points. This repeated-measures quasiexperimental study was conducted in the pediatric emergency and ICU of a tertiary care teaching hospital between January and March 2011. We assessed the baseline knowledge and skills of nursing staff (in-service nurses) and final year undergraduate nursing students (preservice nurses) using a validated questionnaire and a skill checklist, respectively. The participants were then trained on pediatric CPR using standard guidelines. The knowledge and skills were reassessed immediately after training and at 6 weeks after training. A total of 74 participants—28 in-service and 46 preservice professionals—were enrolled. At initial assessment, in-service nurses were found to have insignificant higher mean knowledge scores (6.6 versus 5.8, P=0.08) while the preservice nurses had significantly higher skill scores (6.5 versus 3.2, P<0.001). Immediately after training, the scores improved in both groups. At 6 weeks however, we observed a nonuniform decline in performance in both groups—in-service nurses performing better in knowledge test (10.5 versus 9.1, P=0.01) and the preservice nurses performing better in skill test (9.8 versus 7.4, P<0.001). Thus, knowledge and skills of in-service and preservice nurses in pediatric CPR improved with training. In comparison to preservice nurses, the in-service nurses seemed to retain knowledge better with time than skills

Trek to MDG 4: State of Indian States

Objectives: To provide projections of progress towards the national and state specific MDG 4 using infant mortality rates (IMR) as the indicator. Methods: Infant mortality rates (IMR) of major Indian states for year 1990 were used as the base for evaluating their progress in child health. In the absence of any specific guidelines, the state specific target IMR was derived from the IMR:U5MR (under 5 mortality rate) of the countries whose current U5MR is between 11 and 47 per 1,000 live-births (range of target U5MR for Indian states). The projected IMR for year 2015 was then estimated by the average annual rate of reduction (AARR) from 2005 to 2012. Results: Only a few major states–Karnataka, Maharashtra, Odisha, Punjab, and Tamil Nadu are likely to achieve their respective target IMR within the stipulated time (2015). The other major states, and India as a whole, are likely to miss the MDG 4. The two worst performers, Assam and West Bengal, are likely to achieve their respective targets by 2032 and 2022 respectively. Almost all the states have witnessed a significant progress since the advent of National Rural Health Mission (NRHM) in mid-2005–the AARR has almost doubled in the post-NRHM epoch for most states and India as a whole. Conclusions: The overall progress of most Indian states towards achieving MDG 4 is presently unsatisfactory. However, given the momentum gained since the commencement of NRHM, acceleration in child survival is quite possible in these states

Protocol for administering continuous positive airway pressure in neonates

Continuous positive airway pressure (CPAP) is a simple, inexpensive and gentle mode of respiratory support in preterm very low birth weight (VLBW) infants. It helps by preventing the alveolar collapse and increasing the functional residual capacity of the lungs. Since it results in less ventilator induced lung injury than mechanical ventilation, it should theoretically reduce the incidence of chronic lung disease in VLBW infants. Various devices have been used for CPAP generation and delivery. The relative merits and demerits of these devices and the guidelines for CPAP therapy in neonates are discussed in this protocol

Determinant of early initiation of breastfeeding in a tertiary neonatal unit

Introduction: Initiation of breastfeeding within one hour of birth is an important determinant of successful breastfeeding. National Family and Health Survey -3(NFHS-3) reported that only 23.4% of children &#60; 3 years were breastfed within one hour of birth. Objectives: the purpose of this study is to study the determinant of initiation of breastfeeding within one hour of birth. Setting: Tertiary -level neonatal unit. Material and Methods: All mothers admitted in the postnatal ward were eligible for inclusion; mothers of sick and /or preterm infants were excluded. Enrolled mothers were interviewed between 24 and 72 hours after delivery. Results: The proportion of mothers who initiated breast feeding within one hour of delivery was 32%, between 1-6 hrs were 47% and between 6 to 48 hrs were 21%. Maternal age, education, socioeconomic status, occupation and antenatal or labor room counseling did not influence the initiation of breast feeding within one hour of delivery in univariate analysis. On multivariate analysis, admission in the general ward and delivery by caesarean section were found to be significantly associated with not initiating breastfeeding within one hour (adjusted ORs: 8.79, 2.48 to 31.08, p=0.001 and 6.79, 4.07 to 22.02 p=0.001 respectively). Only about 13% of the infants received prelacteal feeds. Conclusion: Mothers delivering by caesarean section or admitted in the general ward were at high risk of not initiating breastfeeding within one hour. Innovative strategies are required to ensure timely ignition of breastfeeding

Management of neonatal seizures

Seizures in the newborn period constitute a medical emergency. Subtle seizures are the commonest type of seizures occurring in the neonatal period. Myoclonic seizures carry the worst prognosis in terms of long-term neurodevelopmental outcome. Hypoxic-ischemic encephalopathy is the most common cause of neonatal seizures. Multiple etiologies often co-exist in neonates and hence it is essential to rule out common causes such as hypoglycaemia, hypocalcemia, and meningitis before initiating specific therapy. A comprehensive evidence based approach for management of neonatal seizures has been described in this protocol

Chronic lung disease in newborns

Chronic lung disease (CLD) or bronchopulmonary dysplasia (BPD) occurs in preterm infants who require respiratory support in the first few days of birth. Apart from prematurity, oxygen therapy and assisted ventilation, factors like intrauterine/postnatal infections, patent ductus arteriosus, and genetic polymorphisms also contribute to its pathogenesis. The severe form of BPD with extensive inflammatory changes is rarely seen nowadays; instead, a milder form characterized by decreased alveolar septation due to arrest in lung development is more common. A multitude of strategies, mainly pharmacological and ventilatory, have been employed for prevention and treatment of BPD. Unfortunately, most of them have not been proved to be beneficial. A comprehensive protocol for management of BPD based on the current evidence is discussed here

Management of polycythemia in neonates

Polycythemia is defined as a venous hematocrit above 65%. The hematocrit in a newborn peaks at 2 h of age and decreases gradually after that. The relationship between hematocrit and viscosity is almost linear till 65% and exponential thereafter. Increased viscosity of blood is associated with symptoms of hypo-perfusion. Clinical features related to hyperviscosity may affect all organ systems. Neonates born small for gestational age (SGA), infants of diabetic mothers (IDM), and multiple births are at risk for polycythemia. They should therefore undergo screening at 2, 12, and 24 h of age. Polycythemia may be symptomatic or asymptomatic and guidelines for the management of both types based on the current evidence are provided in the protocol
