Temperature measurement of babies born in the pre-hospital setting: analysis of ambulance service data and qualitative interviews with paramedics.

BACKGROUND: Birth before arrival at hospital (BBA) is associated with unfavourable perinatal outcomes and increased mortality. An important risk factor for mortality following BBA is hypothermia, and emergency medical services (EMS) providers are well placed to provide warming strategies. However, research from the UK suggests that EMS providers (paramedics) do not routinely record neonatal temperature following BBA. This study aimed to determine the proportion of cases in which neonatal temperature is documented by paramedics attending BBAs in the South West of England and to explore the barriers to temperature measurement by paramedics. METHODS: A two-phase multi-method study. Phase I involved an analysis of anonymised data from electronic patient care records between 1 February 2017 and 31 January 2020 in a single UK ambulance service, to determine 1) the frequency of BBAs attended and 2) the percentage of these births where a neonatal temperature was recorded, and what proportion of these were hypothermic. Phase II involved interviews with 20 operational paramedics from the same ambulance service, to explore their experiences of, and barriers and facilitators to, neonatal temperature measurement and management following BBA. RESULTS: There were 1582 'normal deliveries' attended by paramedics within the date range. Neonatal temperatures were recorded in 43/1582 (2.7%) instances, of which 72% were below 36.5°C. Data from interviews suggested several barriers and potential facilitators to paramedic measurement of neonatal temperature. Barriers included unavailable or unsuitable equipment, prioritisation of other care activities, lack of exposure to births, and uncertainty regarding responsibilities and roles. Possible facilitators included better equipment, physical prompts, and training and awareness-raising around the importance of temperature measurement. CONCLUSIONS: This study demonstrates a lack of neonatal temperature measurement by paramedics in the South West following BBA, and highlights barriers and facilitators that could serve as a basis for developing an intervention to improve neonatal temperature measurement.

Inequalities in birth before arrival at hospital in South West England: a multimethods study of neonatal hypothermia and emergency medical services call-handler advice.

OBJECTIVES: To examine inequalities in birth before arrival (BBA) at hospitals in South West England, understand which groups are most likely to experience BBA and how this relates to hypothermia and outcomes (phase A). To investigate opportunities to improve temperature management advice given by emergency medical services (EMS) call-handlers during emergency calls regarding BBA in the UK (phase B). DESIGN: A two-phase multimethod study. Phase A analysed anonymised data from hospital neonatal records between January 2018 and January 2021. Phase B analysed anonymised EMS call transcripts, followed by focus groups with National Health Service (NHS) staff and patients. SETTING: Six Hospital Trusts in South West England and two EMS providers (ambulance services) in South West and North East England. PARTICIPANTS: 18 multidisciplinary NHS staff and 22 members of the public who had experienced BBA in the UK. RESULTS: 35% (64/184) of babies conveyed to hospital were hypothermic on arrival. When compared with national data on all births in the South West, we found higher percentages of women with documented safeguarding concerns at booking, previous live births and 'late bookers' (booking their pregnancy >13 weeks gestation). These women may, therefore, be more likely to experience BBA. Preterm babies, babies to first-time mothers and babies born to mothers with disability or safeguarding concerns at booking were more likely to be hypothermic following BBA. Five main themes emerged from qualitative data on call-handler advice: (1) importance placed on neonatal temperature; (2) advice on where the baby should be placed following birth; (3) advice on how to keep the baby warm; (4) timing of temperature management advice and (5) clarity and priority of instructions. CONCLUSIONS: Findings identified factors associated with BBA and neonatal hypothermia following BBA. Improvements to EMS call-handler advice could reduce the number of babies arriving at hospital hypothermic.

Going AWOL in the brain: mind wandering reduces cortical analysis of external events.

Converging evidence from neuroscience suggests that our attention to the outside world waxes and wanes over time. We examined whether these periods of "mind wandering" are associated with reduced cortical analysis of the external environment. Participants performed a sustained attention to response task in which they responded to frequent "nontargets" (digits 0-9) and withheld responses for infrequent "targets" (the letter X). Mind wandering was defined both behaviorally, indicated by a failure to withhold a response to a target, and subjectively, via self-report at a thought probe. The P300 event-related potential component for nontargets was reduced prior to both the behavioral and subjective reports of mind wandering, relative to periods of being "on-task." Regression analysis of P300 amplitude revealed significant common variance between behavioral and subjective markers of mind wandering, suggesting that both markers reflect a common underlying mental state. Finally, control analysis revealed that the effect of mind wandering on the P300 could not be ascribed to changes in motor activity nor was it associated with general arousal. Our data suggest that when trying to engage attention in a sustained manner, the mind will naturally ebb and flow in the depth of cognitive analysis it applies to events in the external environment.
