BackgroundScreening for neonatal hyperbilirubinaemia in the postnatal ward has traditionally been performed using serum bilirubin sampling, but this has significant drawbacks such as risk of infection and slower reporting time.ObjectiveWe aimed to assess the impact of introducing transcutaneous bilirubin (TcBR) testing using TcBR nomogram on the number of serum bilirubin samples sent.MethodsA before-and-after study was performed following the introduction of a protocol integrating the use of the Dragger JM-105 transcutaneous bilirubinometer in the postnatal ward. Only babies born at ≥37 weeks of gestation, weighing ≥2500 g who presented with jaundice after the first 24 hours and within the first 7 days of life were included in the study. The number of total serum bilirubin samples (TSBRs) sent were compared for the 6-month periods before and after (a total of 12 months) implementation of the new protocol.ResultsIn the pre-implementation phase, a total of 882 (49%) out of 1815 babies had at least one serum bilirubin sample taken as opposed to a total of 236 (17%) out of 1394 babies in the post-implementation phase. The odds of performing TSBRs at least one time among babies in post-implementation phase were 79% lower than in pre-implementation phase (OR 0.21, 95% CI 0.18 to 0.25). We also estimated a significant cost saving of approximately US$1800 over a period of 6 monthsConclusionTcBR testing used in conjunction with our proposed nomogram significantly reduces the need for serum bilirubin sampling.

ObjectiveCentral line associated bloodstream infection (CLABSI) is an important cause of morbidity and mortality in the neonatal intensive care unit (NICU). We designed a CLABSI Prevention Package (CPP) to decrease NICU CLABSI rates, using evidence-proven interventions.DesignThis was a quality improvement (QI) project. Data collection was divided into three phases (pre-implementation, implementation and post implementation). SQUIRE2.0 guidelines were used to design, implement and report this QI initiative.SettingA tertiary care level 3 NICU at the Aga Khan University Hospital (AKUH), Karachi, Pakistan.PatientsAll patients admitted to the AKUH NICU from 1 January 2016 to 31 March 2018 who had a central line in place during their NICU admission.InterventionsCPP used evidence-based interventions focusing on hand hygiene, aseptic central line insertion techniques and central line care, prevention of fungal infections and nurse empowerment.Main outcome measuresCLABSI rates pre and post intervention were recorded. Secondary outcomes were risk factors for CLABSI, device (central line) utilisation ratio, CLABSI related mortality and micro-organism profile.ResultsCLABSI rates decreased from 17.1/1000 device days to 5.0/1000 device days (relative risk (RR)=0.36, CI=0.17–0.74). Device (central line) utilisation ratio declined from 0.30 to 0.25. Out of 613 patients enrolled in our study, 139 (22.7%) died. Mortality was higher in CLABSI group (n=20, 44%) as compared with non CLABSI group (n=119, 21.1%) (p<0.001). Gestational age of <27 weeks was an independent risk factor for CLABSI (RR=4.45, CI=1.10–18.25, p=0.03). A total of 158 pathogens were isolated among which 68 were associated with CLABSI. Gram-negative bacteria 31 (47.7%) were the most common cause of CLABSI. Ninety-seven (61%) micro-organisms were multi-drug resistant.ConclusionsCPP was effective in decreasing NICU CLABSI rates and can be used as a model to decrease NICU CLABSI rates in low or middle-income countries.

Impact of a standardised parenteral nutrition protocol: a quality improvement experience from a NICU of a developing country
2022
ObjectiveNutrition societies recommend using standardised parenteral nutrition (SPN) solutions. We designed evidence-based SPN formulations for neonates admitted to our neonatal intensive care unit (NICU) and evaluated their outcomes.DesignThis was a quality improvement initiative. Data were collected retrospectively before and after the intervention.SettingA tertiary-care level 3 NICU at the Aga Khan University in Karachi, Pakistan.PatientsAll NICU patients who received individualised PN (IPN) from December 2016 to August 2017 and SPN from October 2017 to June 2018.InterventionsA team of neonatologists and nutrition pharmacists collaborated to design two evidence-based SPN solutions for preterm neonates admitted to the NICU.Main outcome measuresWe recorded mean weight gain velocity from days 7 to 14 of life. The other outcomes were change in weight expressed as z-scores, metabolic abnormalities, PN-associated liver disease (PNALD), length of NICU stay and episodes of sepsis during hospital stay.ResultsNeonates on SPN had greater rate of change in weight compared with IPN (β=13.40, 95% CI: 12.02 to 14.79) and a smaller decrease in z-scores (p<0.001). Neonates in the SPN group had fewer hyperglycemic episodes (IPN: 37.5%, SPN: 6.2%) (p<0.001), electrolyte abnormalities (IPN: 56.3%, SPN: 21%) (p<0.001), PNALD (IPN: 52.5%, SPN: 18.5%) (p<0.001) and sepsis (IPN: 26%, SPN: 20%) (p<0.05). The median length of stay in NICU was 14.0 (IQR 12.0–21.0) for the IPN and 8.0 (IQR 5.0–13.0) days for the SPN group.ConclusionsWe found that SPN was associated with shorter NICU stay and greater weight gain. In-house preparation of SPN can be used to address the nutritional needs in resource-limited settings where commercially prepared SPN is not available.

IntroductionCentral line-associated bloodstream infections (CLABSI) are the most important cause of morbidity and mortality in critically ill patients. Evidence-based interventions when used in form of a bundle have proven to decrease CLABSI. Our unit has a high CLABSI rate (9/1000 central line days). Therefore, we intend to introduce evidence-based CLABSI prevention package in our practice to improve CLABSI rates in our NICU within limited resources. Methods and analysisThe study will be conducted using preanalysis and postanalysis design from January 2016 to December 2017. It is going to be conducted in three phases with phase I being the preimplimentation phase where retrospective data will be collected. Phase II, implementation phase, where the CLABSI prevention package will be introduced and phase III will be follow-up to see the impact. Primary outcome will be reduction in CLABSI rates.Analysis plan and reportingFor all three phases, descriptive analysis will be performed. Nominal data will be presented as mean±SD, whereas categorical data will be presented as frequencies and percentages. To compare the effect of intervention we will use independent sample t-test for continuous outcomes, whereas Χ2 test will be used for categorical outcomes. Relative risk ratios, 95% CI, and p values will be determined. Incidence density will be calculated and Poisson regression will be used to determine factors associated with incidence of CLABSI. Microbiological profiles and antimicrobial resistance pattern will be reported as pan sensitive, multidrug-resistant organism and carbapenem-resistant organism. SQUIRE V.2.0 guidelines will be used for manuscript writing and reporting.

IntroductionNeonatal jaundice is a common cause of concern in immediate newborn period for parents as well as for the caregivers. Babies with visible jaundice are identified by the healthcare provider, and blood samples are sent for confirmation. Clinical expertise varies from person to person and may lead to sending excessive blood sampling. Obtaining blood bilirubin samples is a painful procedure; it predisposes the baby to infections and requires skilled health personnel. Moreover, laboratory tests are costly and time consuming, leading to unnecessary delays in commencing phototherapy and discharge from hospital. Transcutaneous bilirubinometer has been in use for a long time as screening tool in postnatal wards. With passage of time, its accuracy and validity have improved tremendously.MethodologyWe aim to implement a quality improvement initiative to reduce the number of blood bilirubin samples using transcutaneous bilirubin (TcBR) nomogram in full-term, low-risk babies who are born at our hospital and are admitted in postnatal ward after birth. Using preanalysis and postanalysis study design, this study will be performed in two phases of 6 months each. Data regarding total number of admissions in postnatal wards, demographics, serum bilirubin(TSBR) samplings and need for phototherapy will be recorded in both phases. TcBR will be done and recorded in postimplementation phase.Analysis and resultsComparisons between the two groups will be made. Primary outcome will be reduction in blood bilirubin samples for TSBR after the implementation of TcBr protocol. The proportion of infants having TSBR performed in both periods will be compared. Crude sampling cost of TSBR will be obtained from laboratory, and cost comparison between two phases will be done to look for difference.

Preservation of the Laetoli hominid trackway in Tanzania
1996
The Laetoli hominid footprints in northwestern Tanzania are of major importance in understanding the evolution of humankind. The tracks are 3.6 million years old and pre-date the development of tool-making by one million years, providing clear evidence of the precedence of bipedalism over evolution of the brain. The site was excavated in the late 1970s by Mary Leakey, documented and reburied. In subsequent years, re-vegetation occurred and damage from root growth resulted. Of particular interest in relation to reburial as a preservation strategy is the fact that serious damage occurred to a unique scientific and cultural site because subsequent monitoring and maintenance of the reburial were not carried out. This paper presents an overview of the strategy developed between 1992 and 1994 for the preservation of the trackway, which takes into consideration the many and complex requirements of preserving outdoor sites, and describes the re-excavation, conservation, documentation and reburial of the southern 10m of the trackway completed in the 1995 field season.
