Cardiac arrest in Irish general practice: An observational study from 426 general practices

SETTING Sudden Cardiac Death accounts for approximately 5000 deaths in Ireland each year. Nationally, out-of-hospital cardiac arrest has a very low resuscitation rate, reported at less than 5%. Ireland has a well developed general practice network which routinely manages emergencies arising in the community setting. However, little is known about its potential impact on Sudden Cardiac Death. This study reports on the incidence and management of cardiac arrest in Irish general practice. METHOD A national training/equipment project in defibrillation in general practice (MERIT) has established a network to prospectively report all cardiac arrests with a resuscitation attempt in general practice. Three monthly surveys of the network record events; structured debriefing uses a modified Utstein template to detail events and their outcomes. RESULTS 426 practices reported data during a 36-month period (85-97% response rate to surveys), reporting 144 events, of which data are available on 136 events. 88.4% of events were witnessed, 31.6% by general practice staff. 58.2% of events occurred in the general practice or in the patients home. The general practitioner (GP) was on scene before the ambulance in 72.6% of cases and 52.3% of the patients involved were patients of the GP attending. 52.3% of patients were defibrillated, 32.6% had return of spontaneous circulation at some point and 26 patients (19.5%) were discharged from hospital. CONCLUSIONS Cardiac arrest in general practice is compatible with structured, effective interventions and significant rates of successful resuscitation. All general practices should be capable of providing this care.

Experience of prehospital emergency care among general practitioners in Ireland

Background: Although widely acknowledged, few data exist on the scope of general practice involvement in the management of prehospital emergencies. A study was undertaken to explore the frequency and types of emergencies dealt with and the interventions undertaken by GPs who had completed Immediate Care training. Methods: All participants in Immediate Care courses in Ireland in 2002, 2003 and 2004 were invited to complete an anonymised questionnaire in which they estimated their experience of emergencies since completing a course. Sections dealt with personal/practice information, types of emergencies, interventions used and follow-up training. Results: 448 participants completed courses, 408 were available to participate in the study and 259 (63.5%) responded; 66.6% of GPs responded. The mean reporting period was 29.4 months (range 18–53). Participants included many younger female GPs at the start of their general practice careers. Although most emergencies dealt with were medical, few other patterns emerged in the timing or setting of emergencies. 88% of GPs had called an ambulance in an emergency at least once in the preceding year. 84% of GPs had managed a suspected acute myocardial infarction at least once during the reporting period; seizures, serious injuries, paediatric emergencies and hypoglycaemia were dealt with by up to half of all GPs. Interventions used included intravenous access in a medical emergency (69%), intravenous fluid administration (51%), intravenous morphine (54%), cardiopulmonary resuscitation (37%), defibrillation (21%), use of airway adjuncts (28%) and use of advanced life support drugs in cardiac arrest (24%). Conclusions: GPs make frequent use of a wide range of interventions in prehospital emergencies. Issues relating to tailored training, adequate equipment, collaboration with the emergency services and skills maintenance are highlighted by these data.

Cardiac arrest management in general practice in Ireland: a 5-year cross-sectional study

Objective To document the involvement of general practitioners (GPs) in cardiac arrests with resuscitation attempts (CARAs) and to describe the outcomes. Design A 5-year prospective cross-sectional study of GPs in Ireland equipped with automated external defibrillators (AEDs) and immediate care training by the MERIT Project, with data collection every 3 months over the 5-year period. Practices reported CARAs by quarterly survey with an 89% mean response rate (81–97% for the period). Setting General practices throughout Ireland. Participants 495 GP participated: 168 (33.9%) urban, 163 (32.9%) rural and 164 (33.1%) mixed. Interventions All participating practices received a standard AED and basic life support kit. Training in immediate care was provided for at least one GP in the practice. Main outcome measures Incidence of CARA in participating practices. Return of spontaneous circulation (ROSC) and discharge alive from hospital. Results 36% of practices were involved in a CARA during the 5-year period and 13% were involved in more than one CARA. Of the 272 CARAs reported, ROSC occurred in 32% (87/272) and discharge from hospital in 18.7% (49/262). In 45% of cases, the first AED was brought by the GP and in 65%, the GP arrived before the ambulance service. More cases occurred in rural and mixed settings than urban ones, but the survival rates did not differ between areas. In 65% of cases, the GP was on duty at the time of the incident and 47% of cases occurred in the patients home. Conclusions These outcomes are comparable with more highly structured components of the emergency response system and indicate that GPs have an important role to play in the care of patients in their own communities. GPs experience cardiac arrest cases during the course of their daily work and provide prompt care which results in successful outcomes in urban, mixed and rural settings.

Urban overdose hotspots: a 12-month prospective study in Dublin ambulance services

BACKGROUND Opioid overdose (OD) is the primary cause of death among drug users globally. Personal and social determinants of overdose have been studied before, but the environmental factors lacked research attention. Area deprivation or presence of addiction clinics may contribute to overdose. OBJECTIVES The objective of the study is to examine the baseline incidence of all new ODs in an ambulance service and their relationship with urban deprivation and presence of addiction services. METHODS A prospective chart review of prehospital advanced life support patients was performed on confirmed OD calls. Demographic, geographic, and clinical information, that is, presentation, treatment, and outcomes, was collected for each call. The census data were used to calculate deprivation. Geographical information software mapped the urban deprivation and addiction services against the overdose locations. RESULTS There were 469 overdoses, 13 of which were fatal; most were male (80%), of a young age (32 years), with a high rate of repeated overdoses (26%) and common polydrug use (9.6%). Most occurred in daytime (275) and on the streets (212). Overdoses were more likely in more affluent areas (r = .15; P < .05) and in a 1000-m radius of addiction services. Residential overdoses were in more deprived areas than street overdoses (mean difference, 7.8; t170 = 3.99; P < .001). Street overdoses were more common in the city center than suburbs (χ(2)(1) = 33.04; P < .001). CONCLUSIONS The identified clusters of increased incidence-urban overdose hotspots-suggest a link between environment characteristics and overdoses. This highlights a need to establish overdose education and naloxone distribution in the overdose hotspots.

Screening for atrial fibrillation in general practice : a national, cross-sectional study of an innovative technology

BACKGROUND To test the use of three lead monitoring as a screening tool for atrial fibrillation (AF) in general practice. AF is responsible for up to a quarter of all strokes and is often asymptomatic until a stroke occurs. METHODS 26 randomly selected general practices identified 80 randomly selected patients aged 70 or older from their database and excluded those known to have AF, those with clinical issues or who had not attended for three years. Up to 40 eligible patients/practice were invited to attend for screening. A 2min three-lead ECG was recorded and collected centrally for expert cardiology assessment. Risk factor data was gathered. OUTCOMES (i) point prevalence of AF, (ii) proportion of ECG tracings which were adequate for interpretation, (iii) uptake rate by patients and (iv) acceptability of the screening process to patients and staff (reported separately). RESULTS Of 1447 current patients, 1003 were eligible for inclusion, 639 (64%) agreed to take part in screening and 566 (56%) completed screening. The point prevalence rate for AF was 10.3%-2.1% new cases (12 of 566 who were screened) and 9.5% existing cases (137 of 1447 eligible patients). Only four of 570 (0.7%) screening visits did not record a usable ECG and 11 (2.6%) three lead ECGs required a clarifying 12 lead ECG. CONCLUSIONS Three lead screening for AF is feasible, effective and offers an alternative to pulse taking or 12 lead ECGs. The availability of this technology may facilitate more effective screening, leading to reduced stroke incidence.

Development and process evaluation of an educational intervention for overdose prevention and naloxone distribution by general practice trainees

BackgroundOverdose is the most common cause of fatalities among opioid users. Naloxone is a life-saving medication for reversing opioid overdose. In Ireland, it is currently available to ambulance and emergency care services, but General Practitioners (GP) are in regular contact with opioid users and their families. This positions them to provide naloxone themselves or to instruct patients how to use it. The new Clinical Practice Guidelines of the Pre-hospital Emergency Care Council of Ireland allows trained bystanders to administer intranasal naloxone.We describe the development and process evaluation of an educational intervention, designed to help GP trainees identify and manage opioid overdose with intranasal naloxone.MethodsParticipants (N = 23) from one postgraduate training scheme in Ireland participated in a one-hour training session. The repeated-measures design, using the validated Opioid Overdose Knowledge (OOKS) and Attitudes (OOAS) Scales, examined changes immediately after training. Acceptability and satisfaction with training were measured with a self-administered questionnaire.ResultsKnowledge of the risks of overdose and appropriate actions to be taken increased significantly post-training [OOKS mean difference, 3.52 (standard deviation 4.45); P < 0.001]; attitudes improved too [OOAS mean difference, 11.13 (SD 6.38); P < 0.001]. The most and least useful delivery methods were simulation and video, respectively.ConclusionAppropriate training is a key requirement for the distribution of naloxone through general practice. In future studies, the knowledge from this pilot will be used to inform a train-the-trainer model, whereby healthcare professionals and other front-line service providers will be trained to instruct opioid users and their families in overdose prevention and naloxone use.

Ten years of cardiac arrest resuscitation in Irish general practice

AIM The aim of this study is to establish the role and outcome of general practitioner (GP) involvement in out of hospital cardiac arrest (OHCA) resuscitation in the Republic of Ireland. METHODS A ten year prospective observational study involving a cohort of Irish general practices. SETTING 521 general practice settings distributed throughout the Republic of Ireland, representing approximately one quarter of all practices and a third of Irish GPs. PARTICIPANTS 534 patients suffering cardiac arrest in the community for whom resuscitation was attempted. INTERVENTIONS Cardiac arrest with resuscitation attempted (CARA) in which a GP played a role. RESULTS Over a ten year period almost half of participating practices reported one or more CARAs. A total of 534 CARAs were reported at a variety of locations; 161 (30%) had ROSC (return of spontaneous circulation) at some point, with outcome data available for 147/161; 90 patients survived to hospital discharge. Most survivors for whom follow up data are available were discharged home and were completely independent. The highest rate of survival was achieved when CARAs occurred at a GP practice premises (47.4%). CONCLUSIONS Resuscitation following OHCA is a key task in general practice. Over time a significant number of GPs encounter OHCA, attempt resuscitation and achieve higher survival to hospital discharge rates than occur nationally among OHCAs in Ireland. We conclude that a defibrillator should be routinely available at all general practices and staff should have appropriate resuscitation skills.

EMTs and GPs: what do we think of each other?

Background: Ireland’s health services are undergoing dramatic reorganisation. The establishment of general practitioner (GP) out of hours cooperatives and the integration of current ambulance services into a national ambulance service are among the issues that will impact on prehospital care of emergencies. The study aimed to explore the perceptions of GPs and emergency medical technicians (EMTs) of their own and each other’s roles in the context of such reforms. Methods: A census of all GPs (511) and EMTs (301) in three of Ireland’s eight health board regions was undertaken. A questionnaire containing 31 statements asked respondents to indicate their agreement (or lack of it) in areas such as general relationships, care, and training, roles in emergencies and future developments. Results: Of the personnel contacted, 72% of GPs and 75% of EMTs responded. They report excellent working relationships, agree that the ambulance service is of high quality, and that GPs are willing to provide care in emergencies. However, working links are less satisfactory for EMTs, who report a far higher perception of GP use of emergency ambulances than reported by GPs. Both groups are interested in innovative future links. Discussion: Convergence between the professional groups in different geographic areas and between the disciplines across the areas is striking. They include areas of satisfaction and dissatisfaction. The need for improved liaison between the disciplines is clear.
