Coproducing a library of videos to support families caring for children with gastrostomies: A mixed-methods evaluation with family carers and clinicians.

INTRODUCTION: Many families now perform specialist medical procedures at home. Families need appropriate training and support to do this. The aim of this study was to evaluate a library of videos, coproduced with parents and healthcare professionals, to support and educate families caring for a child with a gastrostomy. METHODS: A mixed-methods online survey evaluating the videos was completed by 43 family carers who care for children with gastrostomies and 33 healthcare professionals (community-based nurses [n = 16], paediatricians [n = 6], dieticians [n = 6], hospital-based nurses [n = 4], paediatric surgeon [n = 1]) from the United Kingdom. Participants watched a sample of videos, rated statements on the videos and reflected on how the videos could be best used in practice. RESULTS: Both family carers and healthcare professionals perceived the video library as a valuable resource for parents and strongly supported the use of videos in practice. All healthcare professionals and 98% (n = 42) of family carers agreed they would recommend the videos to other families. Family carers found the videos empowering and easy to follow and valued the mixture of healthcare professionals and families featured in the videos. Participants gave clear recommendations for how different video topics should fit within the existing patient pathway. DISCUSSION: Families and healthcare professionals perceived the videos to be an extremely useful resource for parents, supporting them practically and emotionally. Similar coproduced educational materials are needed to support families who perform other medical procedures at home. PATIENT OR PUBLIC CONTRIBUTION: Two parent representatives attended the research meetings from conception of the project and were involved in the design, conduct and dissemination of the surveys. The videos themselves were coproduced with several different families.

Paediatric enteral feeding at home: an analysis of patient safety incidents.

AIMS: To describe the nature and causes of patient safety incidents relating to care at home for children with enteral feeding devices. METHODS: We analysed incident data relating to paediatric nasogastric, gastrostomy or jejunostomy feeding at home from England and Wales' National Reporting and Learning System between August 2012 and July 2017. Manual screening by two authors identified 274 incidents which met the inclusion criteria. Each report was descriptively analysed to identify the problems in the delivery of care, the contributory factors and the patient outcome. RESULTS: The most common problems in care related to equipment and devices (n=98, 28%), procedures and treatments (n=86, 24%), information, training and support needs of families (n=54, 15%), feeds (n=52, 15%) and discharge from hospital (n=31, 9%). There was a clearly stated harm to the child in 52 incidents (19%). Contributory factors included staff/service availability, communication between services and the circumstances of the family carer. CONCLUSIONS: There are increasing numbers of children who require specialist medical care at home, yet little is known about safety in this context. This study identifies a range of safety concerns relating to enteral feeding which need further investigation and action. Priorities for improvement are handovers between hospital and community services, the training of family carers, the provision and expertise of services in the community, and the availability and reliability of equipment. Incident reports capture a tiny subset of the total number of adverse events occurring, meaning the scale of problems will be greater than the numbers suggest.

Solid-state semiconductors are better alternatives to arc-lamps for efficient and uniform illumination in minimal access surgery.

INTRODUCTION: Current arc-lamp illumination systems have a number of technical and ergonomic limitations. White light-emitting diodes (LEDs) are energy-efficient solid-state lighting devices which are small, durable and inexpensive. Their use as an alternative to arc-lamp light sources in minimal access surgery has not been explored. This study aims to develop an LED-based endo-illuminator and to determine its lighting characteristics for use in minimal access surgery. METHODS: We developed an LED endo-illuminator using a white LED mounted at the tip of a steel rod. Offline image analysis was carried out to compare the illuminated field using the LED endo-illuminator or an arc-lamp based endoscope in terms of uniformity, shadow sharpness and overall image intensity. Direct radiometric power measurements in light intensity and stability were obtained. Visual perception of fine details at the peripheral endoscopic field was assessed by 13 subjects using the different illumination systems. RESULTS: Illumination from the LED endo-illuminator was more uniform compared to illumination from an arc-lamp source, especially at the closer distance of 4 cm (0.0006 versus 0.0028 arbitrary units--lower value indicates more uniform illumination). The shadows were also sharper (edge widths of 16 versus 44 pixels for the first edge and 15 versus 61 pixels for the second edge). The overall mean image intensity was higher (127 versus 100 arbitrary units) when using the autoshutter mode despite the lower direct radiometric power, about one tenth of the arc-lamp endoscopic system. The illumination was also more stable with less flickering (0.02% versus 5% of total power in non-DC components). Higher median scores on visual perception was also obtained (237 versus 157, p < 0.001). CONCLUSION: The LED endo-illuminator provides more uniform illumination with sharper shadows, less flickering and better illumination for visual perception than the arc-lamp-based system currently used.

Objective evidence for optimum knot configuration.

BACKGROUND: The knot configurations used in clinical practice often are based on tradition and previous training. This study was designed to test the hypothesis that knot quality improves with the addition of a single throw in two-throw and three-throw knots. We tested this hypothesis by using commonly used knot configurations and suture materials. METHODS: Three suture materials, SURGIPRO, BIOSYN and POLYSORB, of 3-0 caliber were used. The break force and integrated force of each material, a single-hitch throw on each material, and 2160 knots of six configurations were measured by using tensiometry. The knot quality scores (KQS) of the different knot configurations were compared by using nonparametric tests. RESULTS: A single-hitch throw on the suture material reduced the break force by up to 40%. The addition of an extra throw improved KQS in 2 x 1 x 1, 2 x 2, and 2 x 2 x 1 knots. The four-throw knot configurations resulted in high KQS and low slippage rates. The 2 x 2 knots were most likely to slip and had the lowest KQS. CONCLUSIONS: If a double-hitch throw is used in the first throw, two to three further throws are recommended. The four-throw knot configurations have the best knot qualities and should generally be used.

Influence of instrument size on endoscopic task performance in pediatric intracorporeal knot tying: smaller instruments are better in infants.

BACKGROUND: The widespread availability of adult minimal access surgical (MAS) equipment together with resource constraints have led pediatric surgeons to adopt the adult setup. This study examined the influence of instrument size on task outcome and physical impact on the surgeon in pediatric endoscopic intracorporeal knot tying. METHODS: Sixteen surgeons participated in this study in which they had to tie surgeon's knots inside a neonatal simulator box with an endoscopic field of 40 mm. All surgeons tied 20 knots using paired pediatric needle-holders and 20 knots using paired adult needle-holders in a randomized order. Knot quality score (KQS) and wrap length were used as indices of knot quality and wrap tightness. Electromyographic (EMG) recordings of the upper limb muscle groups were used to indicate muscular recruitment. A questionnaire on discomfort and instrument preference was also completed by the surgeons. RESULTS: A total of 640 knots were analyzed. Median time was shorter for pediatric needle-holders than for adult needle-holders (94 s vs. 103 s; p < 0.001); however, KQS (0.271 vs. 0.260; p = 0.509) and the tightness around the tube (86 mm vs. 86 mm; p = 0.255) were not significantly different. The proportion of knots that completely slipped was also similar for both needle-holders (19% vs. 22%; p = 0.322). The normalized EMG values when using adult needle-holders were significantly higher than when using pediatric needle-holders in all upper limb muscle groups with the exception of left forearm extensors (p = 0.460). The surgeons reported less discomfort with the pediatric needle-holders in the right forearm and hand, and 13 surgeons expressed overall preference for the smaller instruments. CONCLUSION: Endoscopic knot tying was performed faster in the neonatal simulator box using pediatric needle-holders while maintaining knot quality. Upper limb muscular recruitment was reduced resulting in less discomfort for the surgeon.

Nurse-assisted PEG in children.

The procedures reviewed in this article comprised 83 PEG insertions and 39 PEG changes in children aged six weeks to 19 years (median three years) with weights between 4.7 kg and 80 kg (median 13.5 kg). The complication rate was lower than previously reported paediatric series performed exclusively by medical practitioners. Four children required open conversion and one gastro-colic fistula was discovered five months later.
