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.

Reducing drinking in concurrent problem alcohol and illicit drug users: an impact story

Objective To inform addiction treatment in primary care with respect to psychosocial interventions to reduce drinking in concurrent problem alcohol and illicit drug users, by: exploring the experience of (and evidence for) psychosocial interventions, developing and evaluating a complex intervention to improve implementation. Evaluation of the intervention tested core feasibility and acceptability outcomes for patients and providers.

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.

Paediatric airway management and concerns: a survey of advanced paramedics in Ireland

BackgroundPaediatric airway management is of fundamental importance in the critically unwell child. Pre-hospital paediatric airway management especially endotracheal intubation is however controversial.AimTo explore Irish Advanced Paramedics (APs) training, experience and clinical practice in paediatric airway management as well as to examine clinician attitudes toward this topic.MethodsAn anonymous online survey of all graduates of the University College Dublin AP training program (N = 453).ResultsWith duplicates and failed email deliveries excluded a valid sample of 382 individuals was obtained from whom a response rate of 185/382 (48.4%) was achieved. Three quarters of responding APs worked in urban or mixed practice with the remaining minority operating primarily in rural areas. One quarter of responding APs reported formal training in paediatric intubation. Almost 70% of APs had encountered a child requiring significant airway management in the preceding year. However, this was a rare exposure in terms of overall workload. Basic airway adjuncts were used frequently in such circumstances, with endotracheal intubation having been attempted by only a small minority of APs. Lack of practice was identified by many responding APs as a key issue causing concern in terms of paediatric intubation.ConclusionPaediatric airway management has key relevance for pre-hospital care in Ireland. The overall frequency of exposure to children who may benefit from definitive airway management is however likely to represent a significant barrier to the acquisition and maintenance of competency. The ongoing practice of pre-hospital paediatric intubation by APs may not justify its risks.
