Venous blood point-of-care testing (POCT) for paramedics in urgent and emergency care: protocol for a single-site feasibility study (POCTPara).

The COVID-19 pandemic placed the UK healthcare system under unprecedented pressure, and recovery will require whole-system investment in innovative, flexible and pragmatic solutions. Positioned at the heart of the healthcare system, ambulance services have been tasked with addressing avoidable hospital conveyance and reducing unnecessary emergency department and hospital attendances through the delivery of care closer to home. Having begun to implement models of care intended to increase 'see and treat' opportunities through greater numbers of senior clinical decision makers, emphasis has now been placed upon the use of remote clinical diagnostic tools and near-patient or point-of-care testing (POCT) to aid clinical decision making. In terms of POCT of blood samples obtained from patients in the pre-hospital setting, there is a paucity of evidence beyond its utility for measuring lactate and troponin in acute presentations such as sepsis, trauma and myocardial infarction, although potential exists for the analysis of a much wider panel of analytes beyond these isolated biomarkers. In addition, there is a relative dearth of evidence in respect of the practicalities of using POCT analysers in the pre-hospital setting. This single-site feasibility study aims to understand whether it is practical to use POCT for the analysis of patients' blood samples in the urgent and emergency care pre-hospital setting, through descriptive data of POCT application and through qualitative focus group interviews of advanced practitioners (specialist paramedics) to inform the feasibility and design of a larger study. The primary outcome measure is focus group data measuring the experiences and perceived self-reported impact by specialist paramedics. Secondary outcome measures are number and type of cartridges used, number of successful and unsuccessful attempts in using the POCT analyser, length of time on scene, specialist paramedic recruitment and retention, number of patients who receive POCT, descriptive data of safe conveyance, patient demographics and presentations where POCT is applied and data quality. The study results will inform the design of a main trial if indicated.

Exploring the experiences of community first responders working in a UK ambulance service.

Background: Community first responders (CFRs) work voluntarily to support UK ambulance services by responding to emergencies. They are dispatched via the local 999 call centre and details of incidents in their local area are sent to their mobile phone. They have emergency equipment with them, including a defibrillator and oxygen, and attend a range of incidents, including cardiac arrests. Previous research has looked at the impact the CFR role has had on patient survival, but there is no previous research looking at the experiences of the CFRs while working in a UK ambulance service. Method: This study involved 10 semi-structured interviews, which took place in November and December 2018. One researcher interviewed all the CFRs using a pre-defined interview schedule. The findings of the study were analysed using thematic analysis. Results: The main themes from the study are 'relationships' and 'systems'. The sub-themes of relationships are the relationship between CFRs; the relationship between CFRs and ambulance service staff; and the relationship between CFRs and patients. The sub-themes of systems are call allocation; technology; and reflection and support. Conclusions: CFRs support one another and are encouraging with new starting members. Their relationships with ambulance service staff have improved since CFRs first became active, but there is still room for improvement. The calls that CFRs attend are not always within their scope of practice, but the rate of this occurring is unclear. CFRs are frustrated with the level of technology involved in their role and feel it impacts them attending incidents quickly. CFRs reported attending cardiac arrests on a regular basis and the support that they receive afterwards. Further research should use a survey approach to further explore the experiences of the CFRs based on the themes raised in this study. Using this methodology would identify if these themes are unique to the one ambulance service where this was conducted, or if they are relevant to all UK CFRs.

The experiences and perceptions of wellbeing provision among English ambulance services staff: a multi-method qualitative study.

BACKGROUND: NHS ambulance service staff are at risk of poor physical and mental wellbeing because of the likelihood of encountering stressful and traumatic incidents. While reducing sickness absence and improving wellbeing support to ambulance staff is a key NHS priority, few studies have empirically documented a national picture to inform policy and service re-design. The study aimed to understand how ambulance service trusts in England deal with staff health and wellbeing, as well as how the staff perceive and use wellbeing services. METHODS: To achieve our aim, we undertook semi-structured telephone interviews with health and wellbeing leads and patient-facing ambulance staff, as well as undertaking documentary analysis of ambulance trust policies on wellbeing. The study was conducted both before and during the UK first COVID-19 pandemic wave. The University of Lincoln ethics committee and the Health Research Authority (HRA) granted ethical approval. Overall, we analysed 57 staff wellbeing policy documents across all Trusts. Additionally, we interviewed a Health and Wellbeing Lead in eight Trusts as well as 25 ambulance and control room staff across three Trusts. RESULTS: The study highlighted clear variations between organisational and individual actions to support wellbeing across Trust policies. Wellbeing leads acknowledged real 'tensions' between individual and organisational responsibility for wellbeing. Behaviour changes around diet and exercise were perceived to have a positive effect on the overall mental health of their workforce. Wellbeing leads generally agreed that mental health was given primacy over other wellbeing initiatives. Variable experiences of health and wellbeing support were partly contingent on the levels of management support, impacted by organisational culture and service delivery challenges for staff. CONCLUSION: Ambulance service work can impact upon physical and mental health, which necessitates effective support for staff mental health and wellbeing. Increasing the knowledge of line managers around the availability of services could improve engagement.

Mixed-methods feasibility cluster randomised controlled trial of a paramedic-administered breathlessness management intervention for acute-on-chronic breathlessness (BREATHE): study findings.

Introduction: One-fifth of emergency department presentations by ambulance are due to acute-on-chronic breathlessness. We explored the feasibility of an evaluation-phase, cluster randomised controlled trial (cRCT) of the effectiveness and cost-effectiveness of a paramedic-administered, non-pharmacological breathlessness intervention for people with acute-on-chronic breathlessness at ambulance call-out (BREATHE) regarding breathlessness intensity and conveyance to hospital. Methods: This mixed-methods, feasibility cRCT (ISRCTN80330546) randomised paramedics to usual care or intervention plus usual care. Retrospective patient consent to use call-out data (primary end-point) and prospective patient/carer consent for follow-up was sought. Potential primary outcomes included breathlessness intensity (numerical rating scale) and conveyance. Follow-up included: interviews with patients/carers and questionnaires at 14 days, 1 and 6 months; paramedic focus groups and surveys. Results: Recruitment was during COVID-19, with high demands on paramedics and fewer call-outs by eligible patients. We enrolled 29 paramedics; nine withdrew. Randomisation/trial procedures were acceptable. Paramedics recruited 13 patients, not meeting recruitment target (n=36); eight patients and three carers were followed-up. Data quality was good but insufficient for future sample size estimation. The intervention did not extend call-out time, was delivered with fidelity and was acceptable to patients, carers and paramedics. There were no repeat call-outs within 48 h. All trained paramedics strongly recommended BREATHE as a highly relevant, simple intervention. Conclusion: Patient recruitment to target was not feasible during the pandemic. Training and intervention were acceptable and delivered with fidelity. Results include valuable information on recruitment, consent, attrition and data collection that will inform the design and delivery of a definitive trial.

Trends, variations and prediction of staff sickness absence rates among NHS ambulance services in England: a time series study.

OBJECTIVES: Our aim was to measure ambulance sickness absence rates over time, comparing ambulance services and investigate the predictability of rates for future forecasting. SETTING: All English ambulance services, UK. DESIGN: We used a time series design analysing published monthly National Health Service staff sickness rates by gender, age, job role and region, comparing the 10 regional ambulance services in England between 2009 and 2018. Autoregressive Integrated Moving Average (ARIMA) and Seasonal ARIMA (SARIMA) models were developed using Stata V.14.2 and trends displayed graphically. PARTICIPANTS: Individual participant data were not available. The total number of full-time equivalent (FTE) days lost due to sickness absence (including non-working days) and total number of days available for work for each staff group and level were available. In line with The Data Protection Act, if the organisation had less than 330 FTE days available during the study period it was censored for analysis. RESULTS: A total of 1117 months of sickness absence rate data for all English ambulance services were included in the analysis. We found considerable variation in annual sickness absence rates between ambulance services and over the 10-year duration of the study in England. Across all the ambulance services the median days available were 1 336 888 with IQR of 548 796 and 73 346 median days lost due to sickness absence, with IQR of 30 551 days. Among clinical staff sickness absence varied seasonally with peaks in winter and falls over summer. The winter increases in sickness absence were largely predictable using seasonally adjusted (SARIMA) time series models. CONCLUSION: Sickness rates for clinical staff were found to vary considerably over time and by ambulance trust. Statistical models had sufficient predictive capability to help forecast sickness absence, enabling services to plan human resources more effectively at times of increased demand.

A feasibility cluster randomised controlled trial of a paramedic-administered breathlessness management intervention for acute-on-chronic breathlessness (BREATHE).

Chronic breathlessness, persistent and disabling despite optimal treatment of underlying causes, is a prevalent and frightening symptom and is associated with many emergency presentations and admission to hospital. Breathlessness management techniques used by paramedics may reduce the need for conveyance to hospital. The Breathlessness RElief AT HomE study (BREATHE) aims to explore the feasibility of conducting a definitive cluster randomised controlled trial (cRCT) for people with acute-on-chronic breathlessness who have called an ambulance, to evaluate the effectiveness and cost-effectiveness of a paramedic-administered non-pharmacological breathlessness intervention. The trial is a mixed-methods feasibility cRCT. Eight paramedics will be randomised 1:1 to deliver either the BREATHE intervention in addition to usual care or usual care alone at call-outs for acute-on-chronic breathlessness. Sixty participants will be recruited to provide access to routine data relating to the index call-out with optional follow-up questionnaires at 14 days, 1 month and 6 months. An in-depth interview will be conducted with a subgroup. Feasibility outcomes relating to recruitment, data quality (especially candidate primary outcomes), and intervention acceptability and fidelity will be collected as well as providing data to estimate a sample size for a definitive trial. Yorkshire and The Humber-Sheffield Research Ethics Committee approved the trial protocol (19/YH/0314). The study results will inform progression to, or not, and design of a main trial according to predetermined stop-go criteria. Findings will be disseminated to relevant stakeholders and submitted for publication in a peer-reviewed journal.

Suicide among ambulance service staff: a review of coroner and employment records.

BACKGROUND: There is growing evidence to suggest that ambulance service staff may be at increased risk for suicide; however, few studies have explored risk factors within this occupational group. AIM: To investigate factors commonly associated with ambulance staff suicides. METHOD: Eleven ambulance service trusts across the United Kingdom were asked to return details of staff suicides occurring between January 2014 and December 2015. Coroners were then contacted to request permission to review the records of the deceased. RESULTS: Fifteen suicides were identified (73% male, mean age 42 years). Inquest data were available on 12 deaths. The most common method used was hanging. Possible risk factors identified included recent return to work following a period of sickness absence, poor mental health, relationship and debt problems, history of self-harm and the loss of a driving licence/change in job role. CONCLUSION: Identifying characteristics of suicide among this high-risk group is important to inform the development of suicide prevention initiatives. Additional research is needed with an adequate control group to further explore the risk factors identified in this study.
