Routine Data Collection

An NMR tube has been designed to allow stopped-flow NMR experiments to be done with no modification of the instrument. Thus this technique is made routine for organic and inorganic chemists. The tube can be used with any iron magnet or super-conducting system, but the technique requires a Fourier transform data collection capability. The tube is easily attached to standard stopped-flow supply and stopping syringes, making routine data collection possible at a 0.6 s/spectra sampling rate. A calibration procedure and a sample chemical kinetic study are included to demonstrate the use of the tube.

Over Time

Essential interventions to reduce neonatal deaths that can be effectively delivered in hospitals have been identified. Improving information systems may support routine monitoring of the delivery of these interventions and outcomes at scale. We used cycles of audit and feedback (A&F) coupled with the use of a standardised newborn admission record (NAR) form to explore the potential for creating a common inpatient neonatal data platform and illustrate its potential for monitoring prescribing accuracy. Revised NARs were introduced in a high volume, neonatal unit in Kenya together with 13 A&F meetings over a period of 3  years from January 2014 to November 2016. Data were abstracted from medical records for 15 months before introduction of the revised NAR and A&F and during the 3 years of A&F. We calculated, for each patient, the percentage of documented items from among the total recommended for documentation and trends calculated over time. Gentamicin prescribing accuracy was also tracked over time. Records were examined for 827 and 7336 patients in the pre-A&F and post-A&F periods, respectively. Documentation scores improved overall. Documentation of gestational age improved from <15% in 2014 to >75% in 2016. For five recommended items, including temperature, documentation remained <50%. 16.7% (n=1367; 95%  CI 15.9 to 17.6) of the admitted babies had a diagnosis of neonatal sepsis needing antibiotic treatment. In this group, dosing accuracy of gentamicin improved over time for those under 2  kg from 60% (95%36.1 to 80.1) in 2013 to 83% (95% CI 69.2 to 92.3) in 2016. We report that it is possible to improve routine data collection in neonatal units using a standardised neonatal record linked to relatively basic electronic data collection tools and cycles of A&F. This can be useful in identifying potential gaps in care and tracking outcomes with an aim of improving the quality of care.

Muncar is one of the shark production centers in Java, where the fishing ground in Bali Strait and its surrounding area. Routine data collection was carried out from May 2018 to April 2019 at the Brak Fish Market and the Muncar Coastal Fishing Port (PPP), Banyuwangi to determine the species composition and size distribution of sharks and rays caught in Bali Strait and its surrounding area. Data collection was done by census and almost of all individuals were identified to species level and and measured. During the study, 3.551 individuals of sharks and rays were landed in this port, consisting of 75 species from 25 families (48 species of sharks, one species of ghost shark and 26 rays species). The most common types of sharks belong to Carcharhinidae and for the rays was Dasyatidae. Among these, thirteen species were listed in Appendix II CITES, i.e. Carcharhinus falciformis, Alopias pelagicus, A. superciliosus, Isurus oxyrhinchus, I. paucus, Sphyrna lewini, S. zygaena, Mobula mobular, M. tarapacana, M. thrustoni, Glaucostegus typus, Rhynchobatus australiae and Rhyna ancylostoma. Most of sharks and rays caught were juvenile to adolescent and at immature or maturing stages.

The Sundarbans

BackgroundThe Sundarbans in India is a rural, forested region where children are exposed to a high risk of drowning due to its waterlogged geography. Current data collection systems capture few drowning deaths in this region.MethodsA community-based survey was conducted in the Sundarbans to determine the drowning mortality rate for children aged 1 to 4 years and 5 to 9 years. A community knowledge approach was used. Meetings were held with community residents and key informants to identify drowning deaths in the population. Identified deaths were verified by the child’s household through a structured survey, inquiring on the circumstances around the drowning death.ResultsThe drowning mortality rate for children aged 1 to 4 years was 243.8 per 100 000 children and for 5 to 9 years was 38.8 per 100 000 children. 58.0% of deaths were among children aged 1 to 2 years. No differences in rates between boys and girls were found. Most children drowned in ponds within 50 metres of their homes. Children were usually unaccompanied with their primary caretaker engaged in household work. A minority of children were treated by formal health providers.ConclusionsDrowning is a major cause of death among children in the Sundarbans, particularly those aged 1 to 4 years. Interventions keeping children in safe spaces away from water are urgently required. The results illustrate how routine data collection systems grossly underestimate drowning deaths, emphasising the importance of community-based surveys in capturing these deaths in rural low- and middle-income country contexts. The community knowledge approach provides a low-resource, validated methodology for this purpose.

AbstractThe objective of this study was to monitor the maternal mortality ratio (MMR) in 19 general hospitals after introducing quality assurance in four states in Nigeria.Data collection with a structured maternity record book started in 2008 in ten rural hospitals in Kano and Kaduna State. In 2011, five hospitals from Federal Capital Territory Abuja were added, whilst in 2013 four hospitals were added from Ondo State. The routine data collection was conducted by experienced midwives and supervised by obstetricians from each of the states. However, the data from all four states were collated centrally at Aminu Kano Teaching Hospital for analysis.From 2008 to 2013, 121,808 deliveries were evaluated; MMR fell from 1380 to 360/100,000 in Kaduna State, whilst for Kano State there was a gradual reduction of MMR from 2100/100,000 in 2008 to 1070/100,000 in 2011, and then it increased to 2150/100,000 in 2013. Ondo state had the lowest MMR of 180/100,000 in 2013 followed by Abuja with 240/100,000. The median cesarean section rate was 8.19%, (range 0.97–22.53%), eclampsia/preeclampsia was 4.43% (range 0–56.55%), and postpartum hemorrhage was 3.36% (range 0.81–11.4%).Quality assurance in rural hospitals generates the awareness necessary to improve maternal health and lead to reduction of MMR.
