Is it Appropriate for Patients to be Discharged at the Scene by Paramedics?

Outcomes of adult patients discharged at scene by emergency medical services

BACKGROUND

The outcomes of patients who call an ambulance but are discharged at scene reflect the safety and quality of emergency medical service (EMS) care. While previous studies have examined the outcomes of patients discharged at scene, none have specifically focused on paramedic-initiated discharge. This study aims to describe the outcomes of adult patients discharged at scene by paramedics and identify factors associated with 72-hour outcomes.

METHODS

This was a retrospective data linkage study on consecutive adult EMS patients discharged at scene by paramedics in Victoria, Australia, between 1 January 2015 and 30 June 2019. Multivariable logistic regression was used to investigate factors associated with EMS recontact, ED presentation, hospital admission and serious adverse events (death, cardiac arrest, category 1 triage or intensive care unit admission) within 72 hours of the initial emergency call.

RESULTS

There were 375 758 cases of adults discharged at scene following EMS attendance, of which 222 571 (59.2%) were paramedic-initiated decisions. Of these, 6.8% recontacted EMS, 5.0% presented to ED, 2.4% were admitted to hospital and 0.3% had a serious adverse event in the following 72 hours. The odds of EMS recontact were increased in cases related to mental health (adjusted OR (AOR) 1.41 (95% CI 1.33 to 1.49)), among low-income government concession holders (AOR 1.61 (95% CI 1.55 to 1.67)) and in areas of low socioeconomic advantage (AOR 1.19 (95% CI 1.13 to 1.25)). The odds of hospital admission were increased in cases related to infection (AOR 3.14 (95% CI 2.80 to 3.52)) and pain (AOR 1.93 (95% CI 1.75 to 2.14)). The strongest driver of serious adverse events was an abnormal vital sign (AOR 4.81 (95% CI 3.87 to 5.98)).

CONCLUSION

The occurrence of hospital admission and adverse events is rare in those discharged at scene, suggesting generally safe decision-making. However, increased attention to elderly, multimorbid patients or patients with infection and pain is recommended, as is further research examining the use of tools to aid paramedic recognition of potential for deterioration.

'Knowledge exchange' workshops to optimise development of a risk prediction tool to assist conveyance decisions for suspected seizures - Part of the Risk of ADverse Outcomes after a Suspected Seizure (RADOSS) project

PURPOSE

Suspected seizures present challenges for ambulance services, with paramedics reporting uncertainty over whether or not to convey individuals to emergency departments. The Risk of ADverse Outcomes after a Suspected Seizure (RADOSS) project aims to address this by developing a risk assessment tool utilizing structured patient care record and dispatch data. It proposes a tool that would provide estimates of an individual's likelihood of death and/or recontact with emergency care within 3 days if conveyed compared to not conveyed, and the likelihood of an 'avoidable attendance' occurring if conveyed. Knowledge Exchange workshops engaged stakeholders to resolve key design uncertainties before model derivation.

METHOD

Six workshops involved 26 service users and their significant others (epilepsy or nonepileptic attack disorder), and 25 urgent and emergency care clinicians from different English ambulance regions. Utilizing Nominal Group Techniques, participants shared views of the proposed tool, benefits and concerns, suggested predictors, critiqued outcome measures, and expressed functionality preferences. Data were analysed using Hamilton's Rapid Analysis.

RESULTS

Stakeholders supported tool development, proposing 10 structured variables for predictive testing. Emphasis was placed on the tool supporting, not dictating, care decisions. Participants highlighted some reasons why RADOSS might struggle to derive a predictive model based on structured data alone and suggested some non-structured variables for future testing. Feedback on prediction timeframes for service recontact was received, along with advice on amending the 'avoidable attendance' definition to prevent the tool's predictions being undermined by potential overuse of certain investigations in hospital.

CONCLUSION

Collaborative stakeholder engagement provided crucial insights that can guide RADOSS to develop a user-aligned, optimized tool.

Prehospital COVID-19 patients discharged at the scene - an observational study

BACKGROUND

Emergency medical services (EMS) were the first point of contact for many COVID-19 patients during the pandemic. The aim of this study was to investigate whether the non-conveyance decision of a COVID-19 patient was more frequently associated with a new EMS call than direct ambulance transport to the hospital.

METHODS

All confirmed COVID-19 patients with an EMS call within 14 days of symptom onset were included in the study. Patients were compared based on their prehospital transport decision (transport vs. non-conveyance). The primary endpoint was a new EMS call within 10 days leading to ambulance transport.

RESULTS

A total of 1 286 patients met the study criteria; of these, 605 (47.0%) were male with a mean (standard deviation [SD]) age of 50.5 (SD 19.3) years. The most common dispatch codes were dyspnea in 656 (51.0%) and malaise in 364 (28.3%) calls. High-priority dispatch was used in 220 (17.1%) cases. After prehospital evaluation, 586 (45.6%) patients were discharged at the scene. Oxygen was given to 159 (12.4%) patients, of whom all but one were transported. A new EMS call leading to ambulance transport was observed in 133 (10.3%) cases; of these, 40 (30.1%) were in the group primarily transported and 93 (69.9%) were among the patients who were primarily discharged at the scene (p<.001). There were no significant differences in past medical history, presence of abnormal vital signs, or total NEWS score. Supplemental oxygen was given to 33 (24.8%) patients; 3 (2.3%) patients received other medications.

CONCLUSION

Nearly half of all prehospital COVID-19 patients could be discharged at the scene. Approximately every sixth of these had a new EMS call and ambulance transport within the following 10 days. No significant deterioration was seen among patients primarily discharged at the scene. EMS was able to safely adjust its performance during the first pandemic wave to avoid ED overcrowding.

Lasting Effects of COVID-19 Pandemic on Prehospital Emergency Medical Service Missions

Purpose

The COVID-19 pandemic confronted prehospital emergency medical services (PHEMS) with immense challenges. This study aimed to investigate the development of PHEMS mission numbers and times in the COVID-affected region of Southwest Saxony (SWS).

Patients and Methods

This was a retrospective analysis of PHEMS in SWS during lockdown periods and equal time spans in the previous and following years. Differences were tested for statistical significance using the chi-squared test and one-way analysis of variance (ANOVA).

Results

The total number of missions showed a substantial drop during the first (-16.6%) and the second (-4.5%) lockdown period compared with the previous year. Next-year periods showed a recovery that was nearly equivalent to the starting point. The first lockdown period was not associated with longer overall mission times. The minutes spent at the scene differed significantly between the first lockdown period (31.1 ± 3.52 min), previous year (28.4 ± 4.84 min), and follow-up period (31.8 ± 0.98 min). During the second lockdown, the overall mission times (71.6 ± 2.91 min), response times in minutes (8.9 ± 0.49 min), and minutes spent at the scene (31.4 ± 2.99 min) were significantly longer. The minutes spent at the scene (32.3 ± 18.68 min) and the overall mission time (69.6 ± 1.92 min) remained significantly longer during the control period.

Conclusion

Our data confirm the impact of the SARS-CoV-2 pandemic on German PHEMS. It can be concluded that nationwide lockdown measures led to lasting effects regarding a reduction in the total mission number, transport-on-site released-ratio, and emergency time intervals in the following year, without lockdown restrictions. The lasting effects on the transport-on-site released-ratio and emergency time intervals call for a re-evaluation of the delivery of emergency services during pandemics. These findings can inform future policy decisions and resource allocations to ensure optimal emergency medical services.

The Right to Refuse: Understanding Healthcare Providers' Perspectives on Patient Autonomy in Emergency Care

Healthcare providers in prehospital care and emergency departments are often at the frontline of medical crises, facing a range of ethical dilemmas, particularly when it comes to patients refusing treatment. This study aimed to delve into the attitudes of these providers toward treatment refusal, unearthing the strategies they employ in navigating such challenging situations while actively working in prehospital emergency health services. Our findings showed that, as the participants' age and experience increased, so did their inclination to respect patient autonomy and avoid persuading them to change their decision about treatment. It was noted that doctors, paramedics, and emergency medical technicians demonstrated a deeper understanding of patients' rights than other medical specialists. However, even with this understanding, the prioritization of patients' rights tended to diminish in life-threatening situations, giving rise to ethical dilemmas. This underlines the complexity of balancing the healthcare professionals' responsibilities and the patients' autonomy, which can generate ethically challenging scenarios for those working in emergency healthcare. By investigating these attitudes and experiences, this study seeks to foster a more profound understanding of the ethical quandaries faced by emergency healthcare providers. Our ultimate aim is to contribute to the development of effective strategies that support both patients and professionals in managing these tough circumstances.

A phenomenological interview study with patients being non-conveyed in the ambulance service

BACKGROUND

Non-conveyed patients (i.e. patients who are not transported to a hospital after being assessed by ambulance clinicians) represent a significantly increasing proportion of all patients seeking ambulance care. Scientific knowledge about patients' non-conveyance experiences is sparse. This study describes the lived experiences of non-conveyed patients in an ambulance care context.

METHODS

A reflective lifeworld research (RLR) approach founded on phenomenology is used. Data is derived from nine in-depth interviews with patients not conveyed by the ambulance service in a major Swedish region.

RESULTS

Patients' lived experiences of becoming acutely ill or injured and not conveyed by ambulance to a hospital are characterised by several dynamic movements: losing and regaining situational and bodily control, dependence and autonomy, external competence and inner knowledge, handing over and regaining responsibility, and fear and security.

CONCLUSIONS

Patients' lived experiences of non-conveyance are complex and versatile. Although non-conveyed patients initially experience strong fear and the loss of situational and bodily control, they gradually feel more secure when experiencing confirmation and trust, which evolves into insecurity and uncertainty. The non-conveyance situation's complexity from a patient's perspective implies the need for ambulance organisations to take measures to prevent further suffering. Non-conveyed patients must be taken seriously in their unique situations, requiring ambulance clinicians to reflect and act with a conscious ethical perspective before, during and after their visit.

"Older People Want to Be in Their Own Homes": A Service Evaluation of Patient and Carer Feedback after Pathfinder Responded to Their Emergency Calls

OBJECTIVE

Older people experience high rates of adverse outcomes following emergency department (ED) presentation. There is growing evidence to support alternative care pathways for certain types of emergency medical services (EMS) calls. Pathfinder is one such service and targets patients aged 65 years and over, whose presenting issues can be safely managed at home by immediate paramedic, occupational therapy, and/or physiotherapy interventions. The aim of this service evaluation was to understand how older people feel about being treated at home as a result of EMS calls and to understand their experiences of the Pathfinder service.

METHODS

This was a thematic analysis of open-ended responses recorded from telephone interviews during routine service evaluation with service users (patients or their next-of-kin).

RESULTS

Of 573 service users, telephone interviews were conducted with 429 (75%). Five primary themes were identified: (1) professionalism of the multidisciplinary clinical team; (2) "the right service, in the right place, at the right time"; (3) role of Pathfinder in "getting the ball rolling"; (4) lasting effects of the experience on the patient and his or her next-of-kin; (5) value of skilled communication with the older person.

CONCLUSION

Older people and their next-of-kin voiced a clear preference for hospital avoidance, and strongly valued the opportunity to be treated in their homes at the time of an EMS call rather than default conveyance to the ED. They appreciated the importance of a skilled multidisciplinary team with a follow-up service that effectively positions itself between the acute hospital and community services.

Outcomes of paediatric patients who are not transported to hospital by Emergency Medical Services: a data linkage study

BACKGROUND

Data on the safety of non-transport decisions for paediatric patients attended by Emergency Medical Services (EMS) are lacking. We describe the characteristics and outcomes of paediatric non-transported patients in Victoria, Australia.

METHODS

A retrospective data linkage study of consecutive paediatric (aged <18 years) non-transported patients between January 2015 and June 2019. Patients were linked to ED, hospital admission and death records. Multivariable logistic regression analyses were used to determine factors associated with EMS recontact, ED presentation, hospital admission and an adverse event (death/cardiac arrest, intensive care unit admission or highest ED triage category) within 48 hours of the initial emergency call.

RESULTS

In total, 62 975 non-transported patients were included. The mean age was 7.1 (SD 6.0) years and 48.9% were male. Overall, 2.2% recontacted the EMS within 48 hours, 13.7% self-presented to a public ED, 2.4% were admitted to hospital and 0.1% had an adverse event, including two deaths. Among patients with paramedic-initiated non-transport (excluding transport refusals and transport via other means), 5.6% presented to a public ED, 1.1% were admitted to hospital and 0.05% had an adverse event. In the overall population, an abnormal vital sign on initial assessment increased the odds of hospital admission and an adverse event. Among paramedic-initiated non-transports, cases occurring in the early hours of the morning (04:00-08:00 hours) were associated with increased odds of subsequent hospital admission, while the odds of ED presentation and hospital admission also increased with increasing prior exposure to non-transported cases.

CONCLUSION

Adverse events were rare among paramedic-initiated non-transport cases. Vital sign derangements and attendance by paramedics with higher prior exposure to non-transports were associated with poorer outcomes and may be used to improve safety.

Mastering Linked Datasets: The Future of Emergency Health Care Research

Objectives: The aim of this work is to describe routine integration of prehospital emergency health records into a health master linkage file, delivering ongoing access to integrated patient treatment and outcome information for ambulance-attended patients in Queensland.Methods: The Queensland Ambulance Service (QAS) data are integrated monthly into the Queensland Health Master Linkage File (MLF) using a linkage algorithm that relies on probabilistic matches in combination with deterministic rules based on patient demographic details, date, time and facility identifiers. Each ambulance record is assigned an enduring linkage key (unique patient identifier) and further processing determines whether each record matches with a corresponding hospital emergency department, admission or death registry record. In this study, all QAS electronic ambulance report form (eARF) records from October 2016 to December 2018 where at least 1 key linkage variable was present (n = 1,771,734) were integrated into the MLF.Results: The majority of records (n = 1,456,502; 82.2%) were for transported patients, and 90.1% (n = 1,312,176) of these transports were to public hospital facilities. Of these transport records, 93.9% (n = 1,231,951) matched to emergency department (ED) records and 59.3% (n = 864,394) also linked to admitted patient records. Of ambulance non-transport records integrated into the MLF, 23.6% (n = 74,311) matched with ED records.Conclusion: This study demonstrates robust linkage methods, quality assurance processes and high linkage rates of data across the continuum of care (prehospital/emergency department/admitted patient/death) in Queensland. The resulting infrastructure provides a high-quality linked dataset that facilitates complex research and analysis to inform critical functions such as quality improvement, system evaluation and design.

Using machine learning to predict subsequent events after EMS non-conveyance decisions

Background

Predictors of subsequent events after Emergency Medical Services (EMS) non-conveyance decisions are still unclear, though patient safety is the priority in prehospital emergency care. The aim of this study was to find out whether machine learning can be used in this context and to identify the predictors of subsequent events based on narrative texts of electronic patient care records (ePCR).

Methods

This was a prospective cohort study of EMS patients in Finland. The data was collected from three different regions between June 1 and November 30, 2018. Machine learning, in form of text classification, and manual evaluation were used to predict subsequent events from the clinical notes after a non-conveyance mission.

Results

FastText-model (AUC 0.654) performed best in prediction of subsequent events after EMS non-conveyance missions (n = 11,846). The model and manual analyses showed that many of the subsequent events were planned before, EMS guided the patients to visit primary health care facilities or ED next or following days after non-conveyance. The most frequent signs and symptoms as subsequent event predictors were musculoskeletal-, infection-related and non-specific complaints. 1 in 5 the EMS documentation was inadequate and many of these led to a subsequent event.

Conclusion

Machine learning can be used to predict subsequent events after EMS non-conveyance missions. From the patient safety perspective, it is notable that subsequent event does not necessarily mean that patient safety is compromised. There were a number of subsequent visits to primary health care or EDs, which were planned before by EMS. This demonstrates the appropriate use of limited resources to avoid unnecessary conveyance to the ED. However, further studies are needed without planned subsequent events to find out the harmful subsequent events, where EMS non-conveyance puts patient safety at risk.

Suboptimal prehospital decision- making for referral to alternative levels of care - frequency, measurement, acceptance rate and room for improvement

Background

The emergency medical services (EMS) have undergone dramatic changes during the past few decades. Increased utilisation, changes in care-seeking behaviour and competence among EMS clinicians have given rise to a shift in EMS strategies in many countries. From transport to the emergency department to at the scene deciding on the most appropriate level of care and mode of transport. Among the non-conveyed patients some may suffer from “time-sensitive conditions” delaying diagnosis and treatment. Thus, four questions arise:

How often are time-sensitive cases referred to primary care or self-care advice?

How can we measure and define the level of inappropriate clinical decision-making?

What is acceptable?

How to increase patient safety?

Main text

To what extent time-sensitive cases are non-conveyed varies. About 5–25% of referred patients visit the emergency department within 72 hours, 5% are hospitalised, 1–3% are reported to have a time-sensitive condition and seven-day mortality rates range from 0.3 to 6%.

The level of inappropriate clinical decision-making can be measured using surrogate measures such as emergency department attendances, hospitalisation and short-term mortality. These measures do not reveal time-sensitive conditions. Defining a scoring system may be one alternative, where misclassifications of time-sensitive cases are rated based on how severely they affected patient outcome.

In terms of what is acceptable there is no general agreement. Although a zero-vision approach does not seem to be realistic unless under-triage is split into different levels of severity with zero-vision in the most severe categories.

There are several ways to reduce the risk of misclassifications. Implementation of support systems for decision-making using machine learning to improve the initial assessment is one approach. Using a trigger tool to identify adverse events is another.

Conclusion

A substantial number of patients are non-conveyed, including a small portion with time-sensitive conditions. This poses a threat to patient safety. No general agreement on how to define and measure the extent of such EMS referrals and no agreement of what is acceptable exists, but we conclude an overall zero-vision is not realistic. Developing specific tools supporting decision making regarding EMS referral may be one way to reduce misclassification rates.

Non-conveyance of older adult patients and association with subsequent clinical and adverse events after initial assessment by ambulance clinicians: a cohort analysis

Background

Older adults (age ≥ 65 years) represent a significant proportion of all patients who are not transported to hospital after assessment by ambulance clinicians (non-conveyed patients). This study aimed to fill the knowledge gap in the understanding of the prevalence of older adult non-conveyed patients and investigate their characteristics and risk factors for subsequent and adverse events with those of younger non-conveyed patients comparatively.

Methods

This population-based retrospective cohort study included all adult non-conveyed patients who availed the ambulance service of Region Stockholm, Sweden in 2015; they were age-stratified into two groups: 18–64 and ≥ 65 years. Inter-group differences in short-term outcomes (i.e. emergency department visits, hospitalisations, and mortality within 7 days following non-conveyance) were assessed using multivariate regression analyses.

Results

Older adult patients comprised 48% of the 17,809 non-conveyed patients. Dispatch priority levels were generally lower among older non-conveyed patients than among younger patients. Non-conveyance among older patients occurred more often during daytime, and they were more frequently assessed by ambulance clinicians with nonspecific presenting symptoms. Approximately one in five older adults was hospitalised within 7 days following non-conveyance. Patients presenting with infectious symptoms had the highest mortality risk following non-conveyance. Oxygen saturation level < 95% or systolic blood pressure > 160 mmHg had significantly higher associations with hospitalisation within 7 days following non-conveyance in older adult patients.

Conclusions

Older adult patients have an increased risk for adverse events following non-conveyance. In combination with a complex and variating presentation of symptoms and vital signs proved difficult for dispatch operators and ambulance clinicians to identify and assess, the identified risks raise questions on the patient safety of older adult non-conveyed patients. The results indicate a system failure that need to be managed within the ambulance service organisation to achieve higher levels of patient safety for older non-conveyed patients.

EMS non-conveyance: A safe practice to decrease ED crowding or a threat to patient safety?

BACKGROUND

The safety of the Emergency Medical Service's (EMS's) non-conveyance decision was evaluated by EMS re-contacts, primary health care or emergency department (ED) visits, and hospitalization within 48 h. The secondary outcome was 28-day mortality.

METHODS

This cohort study used prospectively collected data on non-conveyed EMS patients from three different regions in Finland between June 1 and November 30, 2018. The Adjusted International Classification of Primary Care (ICPC2) as the reason for care was compared to hospital discharge diagnoses (ICD10). Multivariable logistic regressions were used to determine factors that were independently associated with adverse outcomes. Results are presented with adjusted odds ratios (aORs) together with 95% confidence intervals (CIs). Data regarding deceased patients were reviewed by the study group.

RESULTS

Of the non-conveyed EMS patients (n = 11,861), 6.3% re-contacted the EMS, 8.3% attended a primary health care facility, 4.2% went to the ED, 1.6% were hospitalized, and 0.1% died 0-24 h after the EMS mission. The 0-24 h adverse event rate was higher than 24-48 h. After non-conveyance, 32 (0.3%) patients were admitted to an intensive care unit within 24 h. Primary non-urgent EMS mission (aOR 1.49; 95% CI 1.25 to 1.77), EMS arrival at night (aOR 1.82; 95% CI 1.58 to 2.09), ALS unit type vs BLS (aOR 1.43; 95% CI 1.16 to 1.77), rural area (aOR 1.74; 95% CI 1.51 to 1.99), and older patient age (aOR 1.41; 95% CI 1.20 to 1.66) were associated with subsequent primary health care visits (0-24 h).

CONCLUSIONS

Four in five non-conveyed patients did not have any re-contact in follow-up period. EMS non-conveyance seems to be a relatively safe method of focusing ED resources and avoiding ED crowding.

Non-Conveyance Due to Patient-Initiated Refusal in Emergency Medical Services: A Retrospective Population-Based Registry Analysis Study in Riyadh Province, Saudi Arabia

This research study aimed to investigate the association between demographic and operational factors and emergency medical services (EMS) missions ending in non-conveyance (NC) due to patient-initiated refusal (PIR). We conducted a retrospective population-based registry study by analyzing 67,620 EMS missions dispatched to the scene during 2018 in the Riyadh province. First, the number and percentages of conveyances statuses were calculated. Then, using crude and adjusted linear and logistic regression analysis, we determined which characteristics were predictors of NC due to PIR. We found that 23,991 (34.4%) of missions ended in NC due to PIR, and 5969 ended in EMS-initiated refusal (8.6%). NC rates due to PIR were higher for women, adults, for missions in Riyadh city, during nighttime, for medical emergencies, and for advanced life support (ALS) crews. We also found the following additional predictors significantly associated with the odds of NC due to PIR in crude regression analyses: age category, geographical location, EMS-shift, time of call, emergency type, and response time. We conclude that the NC rate represents half of all missions for patients requesting EMS, and the rate in Riyadh city has increased compared to previous studies. Most NC cases occur for the highest urgency level of medical emergency type in Riyadh city during the nighttime with ALS crews. NC due to PIR involves younger patients more than elderly, and females more than males. This study’s findings have provided empirical evidence that indicate that conducting further studies involving EMS providers, patients, and the public to identify precise and detailed reasons is required.

Factors Associated with Emergency Medical Service Reattendance in Low Acuity Patients Not Transported by Ambulance

Background: The decision for emergency medical services (EMS) personnel not to transport a patient is challenging: there is a risk of subsequent deterioration but transportation of all patients to hospital would overburden emergency departments. The aim of this large-scale EMS study was to identify factors associated with an increased likelihood of ambulance reattendance within 48 hours in low acuity patients who were not transported by ambulance.Methods: We conducted a 2-year retrospective cohort study using data from the St John New Zealand EMS between 1 July 2016 and 30 June 2018 to investigate demographic and clinical associations with ambulance reattendance.Results: In total, 83,171 low acuity patients not transported by ambulance were included, of whom 4,512 (5.4%) had an EMS ambulance reattend within 48 hours. There were significant associations between EMS reattendance and patient age, sex, ethnicity, deprivation, and event location. Patients aged 60-74 years old had the highest likelihood of ambulance recall (OR 2.87, 95% CI: 2.51-3.28). Males were more likely to have an EMS ambulance reattend within 48 hours (OR 1.17, 95% CI: 1.09-1.25). Māori and Pacific Peoples had a similar likelihood of EMS recall to European/Others; however, the Asian cohort showed a reduced likelihood of reattendance (OR 0.76, 95% CI: 0.62-0.93).There were significant associations between EMS reattendance and non-transport reason, time spent on scene, event type, clinical acuity level (status), and pain score. Shorter (<30 minutes) on scene times were associated with a decreased likelihood of ambulance reattendance, whereas longer scene times (>45 minutes) were associated with an increased likelihood. Medical events were more likely to require reattendance than accident-related events (OR 1.22, 95% CI: 1.13-1.32). Non-transported patients with a severe pain score (7-10/10) were at increased likelihood of requiring reattendance (OR 1.60, 95% CI: 1.33-1.92).Discussion: The overall low rate of EMS reattendance is encouraging. Further research is needed into the clinical presentation of patients requiring ambulance reattendance within 48 hours to determine if there are early warning signs indicative of subsequent deterioration.

Patient experience of non-conveyance following emergency ambulance service response: A scoping review of the literature

INTRODUCTION

Evolution of ambulance service response models has resulted in significant numbers of patients not being conveyed to Emergency Departments. Prior research has attempted to measure patient-safety aspects of non- conveyance with inconclusive results. Several authors have recommended investigation of patient experience as an alternative metric. Understanding patient experience is acknowledged as a core requirement for design and evaluation of changes to healthcare delivery. However, it is unclear to what extent patient experience of non-conveyance is described in academic literature.

AIMS

To map scholarly literature that describes patient experience of non-conveyance and identify knowledge gaps that guide future research.

METHODS

Scoping review guided by the Joanna Briggs Institute (JBI) framework.

RESULTS

Ten studies of heterogenous methodology were included. Commonly, high levels of satisfaction with paramedic care were reported, yet contributing factors to satisfaction were generally not described. Qualitative studies provided deeper insight into experience. Value was attributed to reassurance and being empowered in the decision-making process. Not having concerns validated by paramedics led to negative experiences.

CONCLUSION

There is a scarcity of quality research that has investigated patient experience of non-conveyance following emergency ambulance service response. Methods used by existing research is of low-quality. Patient experience of non-conveyance is not fully known.

Non-conveyance in the ambulance service: a population-based cohort study in Stockholm, Sweden

OBJECTIVES

Non-conveyed patients represent a significant proportion of all patients cared for by ambulance services in the western world. However, scientific knowledge on non-conveyance is sparse. Therefore, the aim of this study was to describe the prevalence of non-conveyance, investigate associations and compare patients' characteristics, drug administration, initial problems and vital signs between non-conveyed and conveyed patients.

DESIGN

A population-based retrospective cohort study.

SETTING

The study setting area, Stockholm, Sweden, has a population of 2.3 million inhabitants, with seven emergency hospitals. Annually, approximately 210 000 assignments are performed by 73 ambulances. All ambulance assignments performed from 1 January to 31 December 2015 were included.

RESULTS

In total, 23 603 ambulance assignments ended in non-conveyance-13.8% of all ambulance assignments performed in 2015. Compared with conveyed patients, non-conveyed patients were younger and more often female (median age 50.1 years for non-conveyed vs 61.7 years for conveyed; female=52 %, both p values <0.001). Approximately half of all ambulance assignments ending in non-conveyance were initially prioritised and dispatched as the highest priority. Non-conveyed patients were more often assessed by ambulance clinicians as presenting non-specific symptoms or symptoms related to psychiatric problems. Low blood glucose levels were highly associated with non-conveyance (adjusted OR (AOR): 15; 95 % CI 11.18 to 20.13), although non-conveyed patients presented abnormal vital signs across all categories of vital signs. Moreover, drugs were more often administered to younger non-conveyed patients. Older patients were more often conveyed and administered drugs once conveyed (AOR: 1.29; 95 % CI 1.07 to 1.56).

CONCLUSIONS

This study shows that non-conveyed patients represent a non-negligible proportion of all patients in contact with ambulance services. In general, most cases of non-conveyance occur at the highest dispatch level, to a large extent involve younger patients, and features problems assessed by ambulance clinicians as non-specific or related to psychiatric symptoms.

Changing role of EMS -analyses of non-conveyed and conveyed patients in Finland

Background

Emergency Medical Services (EMS) and Emergency Departments (ED) have seen increasing attendance rates in the last decades. Currently, EMS are increasingly assessing and treating patients without the need to convey patients to health care facility. The aim of this study was to describe and compare the patient case-mix between conveyed and non-conveyed patients and to analyze factors related to non-conveyance decision making.

Methods

This was a prospective study design of EMS patients in Finland, and data was collected between 1st June and 30th November 2018. Adjusted ICPC2-classification was used as the reason for care. NEWS2-points were collected and analyzed both statistically and with a semi-supervised information extraction method. EMS patients’ geographic location and distance to health care facilities were analyzed by urban–rural classification.

Results

Of the EMS patients (40,263), 59.8% were over 65 years of age and 46.0% of the patients had zero NEWS2 points. The most common ICPC2 code was weakness/tiredness, general (A04), as seen in 13.5% of all patients. When comparing patients between the non-conveyance and conveyance group, a total of 35,454 EMS patients met the inclusion criteria and 14,874 patients (42.0%) were not conveyed to health care facilities. According the multivariable logistic regression model, the non-conveyance decision was more likely made by ALS units, when the EMS arrival time was in the evening or night and when the distance to the health care facility was 21-40 km. Furthermore, younger patients, female gender, whether the patient had used alcohol and a rural area were also related to the non-conveyance decision. If the patient’s NEWS2 score increased by one or two points, the likelihood of conveyance increased. When there was less than 1 h to complete a shift, this did not associate with either non-conveyance or conveyance decisions.

Conclusions

The role of EMS might be changing. This warrants to redesign the chain-of-survival in EMS to include not only high-risk patient groups but also non-critical and general acute patients with non-specific reasons for care. Assessment and on-scene treatment without conveyance can be called the “stretched arm of the emergency department”, but should be planned carefully to ensure patient safety.

A survey of general practitioner's opinion on the proposal to introduce 'treat and referral' into the Irish emergency medical service

BACKGROUND

The introduction of treat and referral by ambulance practitioners is under active consideration in Ireland. The Irish ambulance services have traditionally transported all patients following an emergency (112/999) call to an emergency department. The introduction of treat and referral will present a significant care pathway change.

AIMS

To engage GPs in relation to the proposed introduction of treat and referral.

METHODS

A postal survey of 50 general practices in the southeast of Ireland was completed in 2019 to identify their opinion on the introduction of treat and referral. Descriptive statistics were calculated, and Pearson's chi-square tests were used to identify statistically significant differences among GP cohorts.

RESULTS

A 78% response rate was achieved. Respondents indicated that informal treat and referral was practised by 40% of GPs. A significant majority of GPs indicated that their patients with diabetes or epilepsy would benefit from treat and referral and were happy for paramedics to make appointments posthypoglycaemia or seizure. There was no clear consensus in relation to confining treat and referral to adults only. Barriers to the implementation of treat and referral were a significant issue for GPs.

CONCLUSIONS

GPs are in the main supportive of the introduction of treat and referral; however, they have identified several barriers that may inhibit successful introduction. Importantly, a GP appointment within 48 h does not appear to be a barrier. The adequacy of the working relationships between GPs and the ambulance service and its practitioners appears to have reduced since 2006, which is concerning.

Patient characteristics, triage utilisation, level of care, and outcomes in an unselected adult patient population seen by the emergency medical services: a prospective observational study

Background

Crowding in the emergency department (ED) is a safety concern, and pathways to bypass the ED have been introduced to reduce the time to definitive care. Conversely, a number of low-acuity patients in the ED could be assessed by the emergency medical services (EMS) as requiring a lower level of care. The limited access to primary care in Sweden leaves the EMS nurse to either assess the patient as requiring the ED or to stay at the scene. This study aimed to assess patient characteristics and evaluate the initial assessment by and utilisation of the ambulance triage system and the appropriateness of non-transport decisions.

Methods

A prospective observational study including 6712 patients aged ≥16 years was conducted. The patient records with 72 h of follow-up for non-transported patients were reviewed. Outcomes of death, time-critical conditions, complications within 48 h and final hospital assessment were evaluated. The Mann-Whitney U test, Fisher’s exact test, and Spearman’s rank correlation were used for statistical analysis.

Results

The median patient age was 66 years, and the most common medical history was a circulatory diagnosis. Males received a higher priority from dispatchers and were more frequently assessed at the scene as requiring hospital care. A total of 1312 patients (19.7%) were non-transported; a history of psychiatric disorders or no medical history was more commonly noted among these patients. Twelve (0.9%) of the 1312 patients not transported were later admitted with time-critical conditions. Full triage was applied in 77.4% of the cases, and older patients were triaged at the scene as an ‘unspecific condition’ more frequently than younger patients. Overall, the 30-day mortality was 4.1% (n = 274).

Conclusions

Age, sex, medical history, and presentation all appear to influence the initial assessment. A number of patients transported to ED could be managed at a lower level of care. A small proportion of the non-transported patients were later diagnosed with a time-critical condition, warranting improved assessment tools at the scene and education of the personnel focusing on the elderly population. These results may be useful in addressing resource allocation issues aiming at increasing patient safety.

Stakeholder opinion on the proposal to introduce 'treat and referral' into the Irish emergency medical service

BACKGROUND

The Irish ambulance services have traditionally transported all patients following an emergency (112/999) call, regardless of acuity, to an emergency department (ED). A proposal to introduce Treat and Referral, an established care pathway in some jurisdictions, is under active consideration in Ireland. This will present a significant change. Stakeholder engagement is recognised as an essential component of management of such change. This study has conducted a multicentre, cross-sectional survey exploring opinions on the introduction of Treat and Referral among key Irish stakeholders; consultants in emergency medicine, paramedics and advanced paramedics.

METHODS

Public-sector consultants in emergency medicine (EM), registered paramedics and advanced paramedics, in Ireland at the time of the study, were invited to complete an on-line survey.

RESULTS

A significant finding was that 90% of both cohorts (EM consultants and registered paramedic practitioners) support written after-care instructions being given to referred patients, that > 83% agree that Treat and Referral will reduce unnecessary ambulance journeys and that 70% are in favour of their own family member being offered Treat and Referral. Consensus was reached between respondents that Treat and Referral would improve care and increase clinical judgement of practitioners. Differences were identified in relation to the increased availability of ambulances locally, that only adults should be included, and that research was required to extend Treat and Referral beyond the index conditions. There was no consensus on whether general practitioners (GPs) should be directly informed.

CONCLUSIONS

This study identified that the Irish healthcare practitioners surveyed are supportive of the introduction of Treat and Referral into Ireland. It also affords healthcare policymakers the opportunity to address the concerns raised, in particular the clinical level which will be targeted for inclusion in this extended scope of practice.

Assessing non-conveyed patients in the ambulance service: a phenomenological interview study with Swedish ambulance clinicians

OBJECTIVES

To combat overcrowding in emergency departments, ambulance clinicians (ACs) are being encouraged to make on-site assessments regarding patients' need for conveyance to hospital, and this is creating new and challenging demands for ACs. This study aimed to describe ACs' experiences of assessing non-conveyed patients.

DESIGN

A phenomenological interview study based on a reflective lifeworld research approach.

SETTING

The target area for the study was Stockholm, Sweden, which has a population of approximately 2.3 million inhabitants. In this area, 73 ambulances perform approximately just over 200 000 ambulance assignments annually, and approximately 25 000 patients are non-conveyed each year.

INFORMANTS

11 ACs.

METHODS

In-depth open-ended interviews.

RESULTS

ACs experience uncertainty regarding the accuracy of their assessments of non-conveyed patients. In particular, they fear conducting erroneous assessments that could harm patients. Avoiding hasty decisions is important for conducting safe patient assessments. Several challenging paradoxes were identified that complicate the non-conveyance situation, namely; responsibility, education and feedback paradoxes. The core of the responsibility paradox is that the increased responsibility associated with non-conveyance assessments is not accompanied with appropriate organisational support. Thus, frustration is experienced. The education paradox involves limited and inadequate non-conveyance education. This, in combination with limited support from non-conveyance guidelines, causes the clinical reality to be perceived as challenging and problematic. Finally, the feedback paradox relates to the obstruction of professional development as a result of an absence of learning possibilities after assessments. Additionally, ACs also described loneliness during non-conveyance situations.

CONCLUSIONS

This study suggests that, for ACs, performing non-conveyance assessments means experiencing a paradoxical professional existence. Despite these aggravating paradoxes, however, complex non-conveyance assessments continue to be performed and accompanied with limited organisational support. To create more favourable circumstances and, hopefully, safer assessments, further studies that focus on these paradoxes and non-conveyance are needed.

Ambulance nurses' experiences of deciding a patient does not require ambulance care

AIM

To describe ambulance nurses' experience of deciding a patient does not require ambulance care.

DESIGN

An inductive, empirical study with a qualitative approach.

METHODS

Data collection was conducted through semi-structured interviews, and collected data were analysed with qualitative manifest content analysis. Data were collected during the spring 2017, and eight ambulance nurses participated.

RESULTS

The findings are presented in one main category, which is "Not very ill but a difficult decision" with totally three subcategories. The ambulance nurse's experience of making the assessment when the patient has no need for ambulance care is like walking the balance of slack line. This means that the assessment can be both easy and very difficult but something that definitely requires experience, knowledge and dedication.

Research challenges in prehospital care: the need for a simulation-based prehospital research laboratory

There is a need for improved research in the field of prehospital care. At the same time, there are many barriers in prehospital research due to the complex context, posing unique challenges for research, development, and evaluation. The present paper argues for the potential of simulation for prehospital research, e.g., through the development of an advanced simulation-based prehospital research laboratory. However, the prehospital context is different from other healthcare areas, which implies special requirements for the design of this type of laboratory, in terms of simulation width (including the entire prehospital work process) and depth (level of scenario detail). A set of features pertaining to simulation width, scenario depth, equipment, and personnel and competence are proposed. Close tailoring between these features and the prehospital research problems and context presents great potential to improve and further prehospital research.

Examination of EMS Decision Making in Determining Suitability of Patient Diversion to Urgent Care Centers

Widespread use of Emergency Medicine Services (EMS) for non-emergency care has increased recently, causing overcrowding of the Emergency Department (ED). The increased availability of urgent care centers (UCCs), with their ability to see large numbers of unscheduled patients with more acute presentations, may offer a viable option for many EMS systems to divert non-emergent cases. Using a survey-based study combined with retrospective chart review, EMS provider ability to determine patient suitability for diversion to UCCs was assessed. Results indicated a rate of inappropriate diversion of 11.6%. UCCs may be an alternative option for EMS transport, however strict protocols with medical direction are needed.

Adverse events in prehospital emergency care: a trigger tool study

Background

Prehospital emergency care has developed rapidly during the past decades. The care is given in a complex context which makes prehospital care a potential high-risk activity when it comes to patient safety. Patient safety in the prehospital setting has been only sparsely investigated. The aims of the present study were 1) To investigate the incidence of adverse events (AEs) in prehospital care and 2) To investigate the factors contributing to AEs in prehospital care.

Methods

We used a retrospective study design where 30 randomly selected prehospital medical records were screened for AEs each month in three prehospital organizations in Sweden during a period of one year. A total of 1080 prehospital medical records were included. The record review was based on the use of 11 screening criteria.

Results

The reviewers identified 46 AEs in 46 of 1080 (4.3%) prehospital medical records. Of the 46 AEs, 43 were classified as potential for harm (AE1) (4.0, 95% CI = 2.9–5.4) and three as harm identified (AE2) (0.3, 95% CI = 0.1–0.9). However, among patients with a life-threatening condition (priority 1), the risk of AE was higher (16.5%). The most common factors contributing to AEs were deviations from standard of care and missing, incomplete, or unclear documentation. The most common cause of AEs was the result of action(s) or inaction(s) by the emergency medical service (EMS) crew.

Conclusions

There were 4.3 AEs per 100 ambulance missions in Swedish prehospital care. The majority of AEs originated from deviations from standard of care and incomplete documentation. There was an increase in the risk of AE among patients who the EMS team assessed as having a life-threatening condition. Most AEs were possible to avoid.

Outcomes for Patients Who Contact the Emergency Ambulance Service and Are Not Transported to the Emergency Department: A Data Linkage Study

Objectives: Emergency ambulance services do not transport all patients to hospital. International literature reports non-transport rates ranging from 3.7-93.7%. In 2017, 38% of the 11 million calls received by ambulance services in England were attended by ambulance but not transported to an Emergency Department (ED). A further 10% received clinical advice over the telephone. Little is known about what happens to patients following a non-transport decision. We aimed to investigate what happens to patients following an emergency ambulance telephone call that resulted in a non-transport decision, using a linked routine data-set. Methods: Six-months individual patient level data from one ambulance service in England, linked with Hospital Episode Statistics and national mortality data, were used to identify subsequent health events (ambulance re-contact, ED attendance, hospital admission, death) within 3 days (primary analysis) and 7 days (secondary analysis) of an ambulance call ending in non-transport to hospital. Non-clinical staff used a priority dispatch system e.g. Medical Priority Dispatch System to prioritize calls for ambulance dispatch. Non-transport to ED was determined by ambulance crew members at scene or clinicians at the emergency operating center when an ambulance was not dispatched (telephone advice). Results: The data linkage rate was 85% for patients who were discharged at scene (43,108/50,894). After removal of deaths associated with end of life care (N = 312), 9% (3,861/42,796) re-contacted the ambulance service, 12.6% (5,412/42,796) attended ED, 6.3% (2,694/42,796) were admitted to hospital, and 0.3% (129/42,796) died within 3 days of the call. Rates were higher for events occurring within 7 days. For example, 12% re-contacted the ambulance service, 16.1% attended ED, 9.3% were admitted to hospital, and 0.5% died. The linkage rate for telephone advice calls was low because ambulance services record less information about these patients (24% 2,514/10,634). A sensitivity analysis identified a range of subsequent event rates: 2.5-10.5% of patients were admitted to hospital and 0.06-0.24% of patient died within 3 days of the call. Conclusions: Most non-transported patients did not have subsequent health events. Deaths after non-transport are an infrequent event that could be selected for more detailed review of individual cases, to facilitate learning and improvement.

The ambulance nurse experiences of non-conveying patients

Aims and objectives

To explore ambulance nurses' (ANs) experiences of non‐conveying patients to alternate levels of care.

Background

Increases in ambulance utilisation and in the number of patients seeking ambulance care who do not require medical supervision or treatment during transport have led to increased nonconveyance (NC) and referral to other levels of care.

Design

A qualitative interview study was conducted using an inductive research approach.

Methods

The study was conducted in a region in the middle of Sweden during 2016–2017. Twenty nurses were recruited from the ambulance departments in the region. A conventional content analysis was used to analyse the interviews. The study followed the COREQ checklist.

Results

The ANs experienced NC as a complex and difficult task that carried a large amount of responsibility. They wanted to be professional, spend time with the patient and find the best solution for him or her. These needs conflicted with the ANs' desire to be available for assignments with a higher priority. The ANs could feel frustrated when they perceived that ambulance resources were being misused and when it was difficult to follow the NC guidelines.

Conclusion

If ANs are expected to nonconvey patients seeking ambulance care, they need a formal mandate, knowledge and access to primary health care.

Relevance to clinical practice

This study provides new knowledge regarding the work situation of ANs in relation to NC. These findings can guide future research and can be used by policymakers and ambulance organisations to highlight areas that need to evolve to improve patient care.

Epidemiology of trauma patients attended by ambulance paramedics in Perth, Western Australia

OBJECTIVE

The aim of the study was to describe the epidemiology of trauma in adult patients attended by ambulance paramedics in Perth, Western Australia.

METHODS

A retrospective cohort study of trauma patients aged ≥16 years attended by St John Ambulance Western Australia (SJA-WA) paramedics in greater metropolitan Perth between 2013 and 2016 using the SJA-WA database and WA death data. Incidence and 30 day mortality rates were calculated. Patients who died prehospital (immediate deaths), on the day of injury (early deaths), within 30 days (late deaths) and those who survived longer than 30 days (survivors) were compared for age, sex, mechanism of injury and acuity level. Prehospital interventions were also reported.

RESULTS

Overall, 97 724 cases were included. A statistically significant increase in the incidence rate occurred over the study period (from 1466 to 1623 per 100 000 population year P ≤ 0.001). There were 2183 deaths within 30 days (n = 2183/97 724, 2.2%). Motor vehicle accidents were responsible for most immediate and early deaths (n = 98/203, 48.3% and n = 72/156, 46.2%, respectively). The majority of transported patients were low acuity (acuity levels 3 to 5, n = 60 594/79 887, 75.8%) and high-acuity patients accounted for 2.7% (n = 2176/79 997). Analgesia administration was the most frequently performed intervention (n = 32 333/80 643, 40.1%), followed by insertion of intravenous catheters (n = 25 060/80 643, 31.1%). Advanced life support interventions such as endotracheal intubation were performed in <1% of patients.

CONCLUSION

The trauma incidence rate increased over time and the majority of patients had low-acuity injuries. Focusing research, training and resources solely on high-acuity patients will not cater for the needs of the majority of patients.

A patient-safety and professional perspective on non-conveyance in ambulance care: a systematic review

BACKGROUND

This systematic review aimed to describe non-conveyance in ambulance care from patient-safety and ambulance professional perspectives. The review specifically focussed at describing (1) ambulance non-conveyance rates, (2) characteristics of non-conveyed patients, (3) follow-up care after non-conveyance, (4) existing guidelines or protocols, and (5) influencing factors during the non-conveyance decision making process.

METHODS

We systematically searched MEDLINE, PubMed, CINAHL, EMBASE, and reference lists of included articles, in June 2016. We included all types of peer-reviewed designs on the five topics. Couples of two independent reviewers performed the selection process, the quality assessment, and data extraction.

RESULTS

We included 67 studies with low to moderate quality. Non-conveyance rates for general patient populations ranged from 3.7%-93.7%. Non-conveyed patients have a variety of initial complaints, common initial complaints are related to trauma and neurology. Furthermore, vulnerable patients groups as children and elderly are more represented in the non-conveyance population. Within 24 h-48 h after non-conveyance, 2.5%-6.1% of the patients have EMS representations, and 4.6-19.0% present themselves at the ED. Mortality rates vary from 0.2%-3.5% after 24 h, up to 0.3%-6.1% after 72 h. Criteria to guide non-conveyance decisions are vital signs, ingestion of drugs/alcohol, and level of consciousness. A limited amount of non-conveyance guidelines or protocols is available for general and specific patient populations. Factors influencing the non-conveyance decision are related to the professional (competencies, experience, intuition), the patient (health status, refusal, wishes and best interest), the healthcare system (access to general practitioner/other healthcare facilities/patient information), and supportive tools (online medical control, high risk card).

CONCLUSIONS

Non-conveyance rates for general and specific patient populations vary. Patients in the non-conveyance population present themselves with a variety of initial complaints and conditions, common initial complaints or conditions are related to trauma and neurology. After non-conveyance, a proportion of patients re-enters the emergency healthcare system within 2 days. For ambulance professionals the non-conveyance decision-making process is complex and multifactorial. Competencies needed to perform non-conveyance are marginally described, and there is a limited amount of supportive tools is available for general and specific non-conveyance populations. This may compromise patient-safety.

Non-urgent Emergency Callers: Characteristics and Prognosis

OBJECTIVE

In Denmark, calls to the Danish emergency number 1-1-2 concerning medical emergencies are received by an emergency medical communication center (EMCC). At the EMCC, health care professionals (nurses, paramedics, and physicians) decide the necessary response, depending on the level of emergency as indicated by the Danish Index for Emergency Care. The index states 37 main criteria (symptoms) and five levels of emergency, descending from A (life threatening) to E (not serious). An ambulance is not sent to emergency level-E patients (level-E patients), but they are given other kinds of help/advice. No prior studies focusing on Danish level-E patients exist, hence the sparse knowledge about them. This study aimed to characterize level-E patients in the Central Denmark Region and to investigate their progress in the health care system after the 1-1-2 call, regarding contacting 1-1-2 again, general practitioner and Emergency Department (ED) visits, hospital admission, and death.

METHODS

This is a retrospective follow-up study of callers who contacted the EMCC of the Central Denmark Region and were assessed as level-E patients from August 2013 to July 2014. The study population was identified in the EMCC dispatch software, whose data were supplemented with health care data from three national registries.

RESULTS

Of the 53,414 patients who called 1-1-2 over the study period, 4,962 level-E patients were included in the study. The median age was 47 years (IQR: 24.3-67.7), and 53.4% were men. The most common main criteria were extremity pain - minor wounds. Within 1 day after their 1-1-2 call, 42.1% had a subsequent contact with the health care system. Of those, 5.9% called 1-1-2 again, 24.3% contacted an ED, and 8.6% were admitted. The fatality rate was 0.1%.

CONCLUSIONS

Level-E patients who contacted the EMCC of the Central Denmark Region were most frequently young adults. Almost 60% of level E-patients, who could be tracked, had no further contact with the health care system within a day after their 1-1-2 call. Of those who did, a quarter contacted an ED, indicating that level-E patients needed medical attention. The low fatality rates suggest limited undertriage, that is, level-E patients do not seem to need emergency medical service transportation. Further studies on undertriage among other things are needed.

Impact of population ageing on growing demand for emergency transportation to emergency departments in Western Australia, 2005-2020

OBJECTIVE

The aim of the present paper is to quantify the impact of population ageing on demand for emergency transportation (ET) to EDs in Western Australia (WA).

METHODS

A population-based longitudinal study using the statewide ED presentation data from 2005-2014 was used to predict ET demand in 2020, stratified by age group and sex.

RESULTS

From 2005 to 2014, 14.9% of all ED presentations arrived by ET. The number rose from 94 369 (13.9%) in 2005 to 153 374 (15.5%) in 2014, a compound annual growth of 5.5%. Of those presentations, 55.2% resulted in hospital admission. The proportion was higher in older age groups (64.5% in 65-74 years, 67.1% in 75-84 years and 68.4% in ≥85 years). Of ED presentations arriving by ET in age group ≥65 years, 70.9% were Australasian Triage Scale category 1, 2 or 3. The rate of ET per 1000 population increased in all age groups and sex. The highest growth was in the older age groups: from 86.6, 187.0 and 512.1 in ages 65-74 years, 75-84 years and ≥85 years, respectively, in 2005 to 102.5, 226.7 and 613.6 in 2014, and are expected to increase to 115.1, 264.3 and 707.7 by 2020. The ET demands in these age groups were projected to increase annually by 5.0%, 3.6% and 4.9%, respectively, in the next 6 years, comparing to less than 4.5% in the younger age groups.

CONCLUSION

There has been a continuous rise in ET demand in WA, particularly in older people who have a higher urgency and requirement for admission.

Paramedic Attendance to Older Patients in Australia, and the Prevalence and Implications of Psychosocial Issues

OBJECTIVE

This study aims to determine the number and reasons for emergency paramedic attendances to older adults in Victoria, Australia. A second aim is to investigate the prevalence of psychosocial factors that may contribute to older patients requiring emergency paramedic attendance.

METHODS

This descriptive retrospective study analyzed all emergency paramedic attendances to patients aged 65 or older between July 1, 2011 and June 30, 2014 in Victoria, Australia. Fully de-identified data were extracted from the Ambulance Victoria Data Warehouse. Data included demographic and clinical variables such as age, gender, case nature (cause), past history, management and transportation, paramedic final assessment (diagnosis), social situation, past history; as well as free text case descriptions.

RESULTS

A total of 596,579 patients 65 years or older were attended by emergency paramedics during the study period. This accounted for 24.1% of Ambulance Victoria workload during that period. The mean (SD) age of patients was 79.8(8.2). The majority (70.7%) of cases involved patients at private residences. The most common final assessments were pain (18.7%), cardiac problem (7.2%), infection (6.9%), trauma (6.7%), other/unknown (6.4%), and respiratory problem (5.7%). The vast majority of patients were transported to hospital (82.8%). Psychosocial issues were evident in the free text case descriptions of more than 91,000 cases.

CONCLUSION

Paramedics attended almost 600,000 patients 65 years and older during the study period. Patients suffered from conditions including, pain, trauma, infections, cardiac complaints, and respiratory problems. Free text case descriptions provided more detail and insight into the reasons for emergency paramedic attendance. Psychosocial problems were far more prevalent than indicated by the "final assessment" field. Further research is required to determine the reasons and implications of this.
