neonatal wireless monitoring system for intensive care

Conditions: Preterm Infant; Infant, Newborn; Low; Birthweight, Extremely (999 Grams or Less)

Summary: babies who require intensive care need to have their heart rate, oxygen levels and temperature measured continuously using specially designed monitors. these monitors allow the clinical team to constantly assess the baby and see if they are becoming unwell. however, these monitors each have separate wires to connect them to the baby. another important part of care in these babies is being able to allow parents to hold their babies, getting them out of their incubators to be cuddled. this is called kangaroo care and has been shown to impact on long term health for both babies and parents. we have designed a system to free babies of the wires that tether them to the monitors. this system has been tested in adults and we now want to test them on the babies. there are two study parts with two different questions: 1. how good is the data? this will compare the new wireless system with the existing system. babies will have both standard wired monitors and the new wireless monitor on at the same time so we can compare the data to see how good is the quality of the data collected on the new system. 2. what do parents and staff think about the wireless system during kangaroo care? babies who no longer need monitoring (but who previously had been monitored with the wired system), will have the wireless system attached and the parent will take their baby from the cot for kangaroo care. after the baby has been placed back in the cot, we will conduct interviews with the parent and the nurse to find out what they thought of the new system. we hope this will help the investigators to understand about how good the data is we collect and how we might be able to improve the system.

summary of study design this is a single-center study recruiting from the neonatal intensive care unit (nicu) at addenbrooke's hospital, cambridge. there are 2 study parts: 1. quantitative assessment of the accuracy of the new system in comparison with standard clinical monitoring systems 2. qualitative assessment of parent and staff views of caring for babies with the new system in comparison with conventional clinical monitoring systems quantitative study arm study population up to 24 participants will be recruited from the addenbrooke's hospital nicu. the participants will be recruited from three groups, defined by the bapm categories of care the population size has been selected to include sufficient babies to collect a reasonable amount of data to ascertain, with confidence, our defined outcomes. furthermore, the data should come from across the range of variables seen in babies requiring intensive care while limiting exposure of the infants at most risk. the study will be performed in a stepwise fashion, starting with those infants requiring lower dependency care. inclusion criteria * babies being cared for on the nicu at addenbrookes hospital * written, informed parental consent exclusion criteria * known to have an intolerance to silicone or silicone gel adhesives. * has a pacemaker or other implanted electronic device. planned procedures participants will have the newly developed wireless sensors for ecg, pulse oximetry, and temperature attached adjacent to the current clinical, wired sensors. once the application sites have been identified and prepared, the sensors will be placed on the baby by an appropriately trained individual. the wireless receiver will connect to a separate patient monitor to log the comparative data. this study monitor will be covered and silenced such that data will not be visible to the clinical team, and it will not be possible to confuse the study monitor from the 'clinical' monitor. the sensors will be in place for a period of up to 24 hours. after this period, the study sensors will be removed, and the site inspected by a member of the research team and scored using the standard tissue viability scoring system already in use on the unit. the sensors will be disposed of in keeping with the unit and trust policy. after the study intervention, a questionnaire will be given to the nurse caring for the baby to determine their views on the wireless system. data collection data will be collected from both the study monitor and the 'clinical' monitor. the data are formed of two types: parameter data and waveform data. parameter data has a two-second interval. the waveform data has a period of approximately 4ms. qualitative study arm study population up to 10 participants will be recruited from the addenbrooke's hospital. this is in line with other studies with similar cohorts and balances the need to obtain a range of views and experiences, with the imposition on parents' time in such an environment. inclusion criteria * bapm level transitional care babies who do not clinically require vital sign monitoring. * the baby has had vital sign monitoring at some point during their stay on the unit. * written, informed parental consent exclusion criteria * known to have an intolerance to silicone or silicone gel adhesives. * has a pacemaker or other implanted electronic medical device. planned procedure babies who are not indicated for vital sign monitoring will have the wireless monitoring system attached. once the application sites have been identified and prepared, the sensors will be placed on the baby by an appropriately trained individual. the wireless receiver will connect to the study monitor to log the vital sign data, and all alarms will be silenced. the monitor will be covered and silenced such that it will not impact on clinical care. the baby will be transferred from the cot/incubator to the parent for kangaroo care as per standard nicu procedure. the parent and baby will remain in contact for as long as the parent is comfortable, and the baby remains stable and in keeping with unit policy and procedures. the baby will then be transferred back to the cot, and monitoring will be removed. semi-structured interviews lasting approximately 30 minutes will then be conducted with, (i) the nurse, and (ii) the parent(s). these interviews will focus on previous experiences with vital sign monitoring systems, and their experience of using the new wireless system.
