Improving the longevity of intravenous cannulas in sick neonates admitted to NICU in a tertiary care centre: a quality improvement project.

BACKGROUND: Neonatal intravenous cannulation, especially in preterms, is more challenging than in children or adults. Placement of an intravenous cannula is painful and many cannulas need frequent changing due to complications. Each attempt at cannulation creates an entry for skin flora to cause systemic bacteraemia. This study was undertaken at a level III NICU. The team attempted to prolong the existing cannula longevity to reduce the frequency of intravenous cannulation thereby reducing handling and pain. OBJECTIVES: To improve the longevity of peripherally inserted intravenous cannula in sick neonates in NICU from the current 25.7 hours to 36 hours or more, over a span of 6 weeks. MATERIALS AND METHODS: The quality improvement (QI) team comprised resident doctors and staff nurses. A fishbone analysis was used to identify factors that affected the longevity of intravenous cannulas. Five WHYs technique was used to identify the cause behind early cannula removal. Both techniques identified the fixation technique used at the study centre for target intervention. Plan-Do-Study-Act cycles were planned to explore different fixation techniques to improve cannula longevity. The unpaired t-test and the χ2 tests were applied to analyse statistical significance. RESULTS: We achieved significant improvement in cannula longevity from 25.7 hours to 39.6 hours just by improving the fixation technique over 6 weeks with a p=0.0006. CONCLUSIONS: The QI study was successful and is adopted for routine practice. Such initiatives would greatly impact babies in low-resource settings and in transit.

Screening of Extended Family Members of Thalassemia Major Children as a Thalassemia Preventive Strategy.

Background: Thalassemia is considered as the most common single gene disorder worldwide. Preventive measures include identification of thalassemia carriers (traits) through screening, genetic counselling and prenatal diagnosis to reduce the incidence. This study aims at estimating the prevalence of carrier status detection among the extended family members of children having thalassemia major so as to use it as a screening prevention strategy with appropriate counselling. Methods: This cross-sectional study was conducted in thalassemia unit of Pediatric Department of a tertiary care teaching hospital over a period of 18 months. Blood samples were collected from 117 extended family members (EFM) of 23 children with thalassemia major to carry out investigations such as Complete Blood Counts (CBC), Naked Eye Single Tube Red Cell Osmotic Fragility Test (NESTROFT), Reticulocyte count, High Performance Liquid Chromatography(HPLC) and serum ferritin. Reports were analysed to find out the prevalence of carriers. Results: Among 117 EFM, 62 (52.9%) were males while 55(47.1%) were females. Mean age distribution in this study was 16.49 years (8.5). Prevalence of thalassemia trait (carrier) was 35%. NESTROFT test was positive in 57(48.7%) participants. The binary logistic regression found only positive NESTROFT test as a predictor (adjusted OR=0.022, P=0.001) of having raised HbA2 (HbA2≥3.5 %). Conclusion: Screening of thalassemia carrier by targeting extended family members of thalassemia major children could yield more carrier cases and targeted counselling could help effectively in decreasing the number of children born with thalassemia major. This strategy could be included in future plan of national prevention programme for thalassemia.
