Barriers to CPR initiation and continuation during the emergency call relating to out-of-hospital cardiac arrest: A descriptive cohort study.

AIM: To describe the barriers to cardiopulmonary resuscitation (CPR) initiation and continuation in emergency calls for out-of-hospital cardiac arrest (OHCA). METHODS: We analysed 295 consecutive emergency calls relating to OHCA over a four-month period (1 January - 30 April 2021). Calls included were paramedic-confirmed, non-traumatic, non-EMS-witnessed OHCA, where the caller was with the patient. Calls were listened to in full and coded in terms of barriers to CPR initiation and continuation, and patient and caller characteristics. RESULTS: Overall, CPR was performed in 69% of calls and, in 85% of these, callers continued performing CPR until EMS arrival. Nearly all callers (99%) experienced barriers to CPR initiation and/or continuation during the call. The barriers identified were classified into eight categories: reluctance, appropriateness, emotion, bystander physical ability, patient access, leaving the scene, communication failure, caller actions and call-taker instructions. Of these, bystander physical ability was the most prevalent barrier to both CPR initiation and continuation, occurring in 191 (65%) calls, followed by communication failure which occurred in 160 (54%) calls. Callers stopping or interrupting CPR performance due to being fatigued was lower than expected (n = 54, 26% of callers who performed CPR). Barriers to CPR initiation that related to bystander physical ability, caller actions, communication failure, emotion, leaving the scene, patient access, procedural barriers, and reluctance were mostly overcome by the caller (i.e., CPR was performed). CONCLUSION: Barriers to CPR initiation and continuation were commonly experienced by callers, however they were frequently overcome. Future research should investigate the strategies that were successful.

Survival to hospital discharge is equivalent to 30-day survival as a primary survival outcome for out-of-hospital cardiac arrest studies.

AIM: The 2015 Utstein guidelines stated that 30-day survival could be used as an alternative to survival to hospital discharge (STHD) as the primary survival outcome in out-of-hospital cardiac arrest (OHCA) studies. We sought to ascertain the equivalence (concordance) of these two survival outcome measures. METHODS: We conducted a population-based retrospective cohort study of OHCA patients who were attended by St John Western Australia (SJ-WA) paramedics in Perth, WA between 1999 and 2018. OHCA patients were included if they received either an attempted resuscitation by SJ-WA or bystander defibrillation; were a resident of WA; and were transported to a hospital emergency department (ED). STHD was determined through hospital record review and 30-day survival via the WA Death Registry and cemetery registration data. RESULTS: The study cohort comprised a total of 7953 OHCA patients, predominantly male (70%), with a median (IQR) age of 63 (46-77 years), a presumed cardiac arrest aetiology (78.9%), and the majority occurred in a private residence (66.8%). Survival rates were identical for STHD and 30-day survival, with both being (13.78%, 95% CI: 13.02-14.54%) (p = 0.99). The overall concordance between the two survival rates was 99.6%. There were only 30 (0.4%) discordant cases in total: 15 cases with STHD-yes but 30-day survival-no; and 15 cases with STHD-no but 30-day survival-yes. CONCLUSION: We found that STHD and 30-day survival were equivalent survival metrics in our OHCA Registry. However, given potential differences in health systems, we suggest that 30-day survival is likely to enable more reliable comparisons across jurisdictions.

'I think he's dead': A cohort study of the impact of caller declarations of death during the emergency call on bystander CPR.

BACKGROUND: In emergency calls for out-of-hospital cardiac arrest (OHCA), dispatchers are instrumental in the provision of bystander cardiopulmonary resuscitation (CPR) through the recruitment of the caller. We explored the impact of caller perception of patient viability on initial recognition of OHCA by the dispatcher, rates of bystander CPR and early patient survival outcomes. METHODS: We conducted a retrospective cohort study of 422 emergency calls where OHCA was recognised by the dispatcher and resuscitation was attempted by paramedics. We used the call recordings, dispatch data, and electronic patient care records to identify caller statements that the patient was dead, initial versus delayed recognition of OHCA by the dispatcher, caller acceptance to perform CPR, provision of bystander-CPR, prehospital return of spontaneous circulation (ROSC), and ROSC on arrival at the Emergency Department. RESULTS: Initial recognition of OHCA by the dispatcher was more frequent in cases with a declaration of death by the caller than in cases without (92%, 73/79 vs. 66%, 227/343, p < 0.001). Callers who expressed such a view (19% of cases) were more likely to decline CPR (38% vs. 10%, adjusted odds ratio 4.59, 95% confidence interval 2.49-8.52, p < 0.001). Yet, 15% (12/79) of patients described as non-viable by callers achieved ROSC. CONCLUSION: Caller statements that the patient is dead are helpful for dispatchers to recognise OHCA early, but potentially detrimental when recruiting the caller to perform CPR. There is an opportunity to improve the rate of bystander-CPR and patient outcomes if dispatchers are attentive to caller statements about viability.

"Sorry, what did you say?" Communicating defibrillator retrieval and use in OHCA emergency calls.

BACKGROUND: The defibrillator prompt, which directs callers to retrieve a defibrillator during out-of-hospital cardiac arrest, is crucial to the emergency call because it can save lives. We evaluated communicative effectiveness of the prompt instated by the Medical Priority Dispatch System™ Version 13, namely: if there is a defibrillator (AED) available, send someone to get it now, and tell me when you have it. METHODS: Using Conversation Analysis and descriptive statistics, we examined linguistic features of the defibrillator sequences (call-taker prompt and caller response) in 208 emergency calls where non-traumatic out-of-hospital cardiac arrest was confirmed by the emergency medical services, and they attempted resuscitation, in the first six months of 2019. Defibrillator sequence durations were measured to determine impact on time to CPR prompt. The proportion of cases where bystanders retrieved defibrillators was also assessed. RESULTS: There was low call-taker adoption of the Medical Priority Dispatch System™ Version 13 prompt (99/208) compared to alternative prompts (86/208) or no prompt (23/208). Caller responses to the Version 13 prompt tended to be longer, more ambiguous or unrelated, and have more instances of repair (utterances to address comprehension trouble). Defibrillators were rarely brought to the scene irrespective of defibrillator prompt utilised. CONCLUSION: While the Version 13 prompt aims to ensure the use of an available automatic external defibrillator, its effectiveness is undermined by the three-clause composition of the prompt and exclusion of a question structure. We recommend testing of a re-phrased defibrillator prompt in order to maximise comprehension and caller action.

Caller resistance to perform cardio-pulmonary resuscitation in emergency calls for cardiac arrest.

A key objective of an emergency call for cardiac arrest is to recruit a bystander to perform cardio-pulmonary resuscitation (CPR) until the ambulance arrives. Emergency medical services worldwide work towards increasing the rate of bystander-CPR, and existing research has identified a number of physical barriers to the provision of bystander-CPR. Yet, little is known about the specific ways in which emergency callers resist recruitment to perform basic first-aid, sometimes in the absence of any physical obstacle. This study investigated 65 emergency calls for cardiac arrest received in Australia in 2014 and 2015, in which the callers initially resisted CPR. We used conversation analysis to examine callers' practices to resist recruitment and call-takers' practices to counter this resistance. We found that callers who resisted CPR typically provided an account. When callers accounted for their resistance on deontic grounds, they expressed that CPR was not a possible course of action (e.g. "I can't do it"). When callers provided an epistemic account, their justification was based on their knowledge or opinion (e.g. "I think it's too late"). Our findings suggest that epistemic resistance can be a barrier to bystander-CPR. We identified two practices used by call-takers to address caller resistance based on epistemics. Providing more context on the purpose of CPR (e.g. "this is to help him in the meantime") seemed effective in persuading callers to perform CPR. By contrast, aligning with the caller's epistemic and deontic rights (e.g. "it's up to you") did not seem effective in persuading callers.

Issues affecting nurses' capability to use digital technology at work: An integrative review.

BACKGROUND: Digital capability, that is the ability to live, work, participate and thrive in a digital world, is imperative for nurses because increasingly nurses' work and patient outcomes are influenced by technology. AIM: To evaluate and synthesise the evidence regarding the development of digital capability in nurses and the strategies that support effective integration of digital skills into the workplace. DESIGN: Whittemore and Knafl's methodology, following the preferred reporting items for systematic reviews (PRISMA) guidelines. DATA SOURCES: CINAHL, Embase, PsychINFO, Medline (Ovid) and PubMed databases were searched for articles published in English from 2008-2019. Search terms included; digital capabil*, digital literacy, informatics, nursing informatics, health informatics, nurs*, knowledge, knowledge integration, competency, continuing education, nursing skills, workplace and work environment. REVIEW METHODS: A total of 35 studies were retrieved for quality assessment by two reviewers using standardised critical appraisal instruments from the Joanna Briggs Institute (JBI-MAStARI and JBI-QARI). Minimum essential criteria and scores were agreed prior to appraisal. RESULTS: The 17 studies included comprised quantitative (n = 7), qualitative (n = 8) and mixed methods (n = 2). Integration of digital capability in nurses' workplaces is dependent on user proficiency and competence (theme 1). Nurses use technology to access data at the point of care, specifically accessing evidence to guide care (theme 2a) as well as accessing the medical records (theme 2b). Nurses have several concerns related to the use of technology at point of care (theme 3), some of which can be resolved through investment for implementation (theme 4). CONCLUSIONS: There are key attributes of digitally proficient nurses. Nurses with these attributes are more inclined to use digital technology in their work. Involvement of the nurses as end users in the development of digital systems to ensure they are fit for purpose, alongside investment in professional development opportunities for nurses to develop digital capability, should be prioritised.

Student Nurses' Digital Literacy Levels: Lessons for Curricula.

The rapid uptake of technology is changing the way health professionals provide care to patients and communities. While this presents opportunities to improve, enhance, and positively transform care and treatment, graduates must have the requisite knowledge, skills, and attitudes to make effective use of the technology and data available to them. This research explored nursing students' self-reported digital literacy levels. We undertook a student survey at one university in Australia, utilizing the validated Self-Assessment Nursing Informatics Competencies Scale-SF30 instrument. Overall, 90% of students rated their basic computer knowledge and skills as at least "competent" including performing basic troubleshooting, using the Internet, and conducting online literature searches. However, only 55% of students considered their overall applied computer skills as at least "competent," which included using applications for diagnostic coding and to extract data from clinical data sets. Students have digital literacy in everyday settings; however, their ability to translate this into practice is limited, restricting their access to and use of digital tools in the workplace. Our findings provide the opportunity to address practice issues related to digital literacy and to embed appropriate content in curricula to enable the delivery of improved patient care and the appropriate use of data in various settings.
