Paramedics assessing Elders at Risk for Independence Loss (PERIL): Derivation, Reliability and Comparative Effectiveness of a Clinical Prediction Rule

Delivery of public health interventions by the ambulance sector: a scoping review

BACKGROUND

With millions of unscheduled patient contacts every year and increasing call outs clustered around the most deprived communities, it is clear the ambulance sector could have a role to play in improving population health. However, the application and value of a public health approach within the ambulance sector has not been comprehensively explored. A scoping review was undertaken to explore the role of the ambulance sector in the delivery of public health interventions and what impact this has on population health and ambulance sector outcomes.

METHODS

A search strategy was developed on MEDLINE and translated to other major medical and health related bibliographic databases (Embase; CINAHL; HMIC; Science and Social Sciences Citation Index; Cochrane Library) to identify literature published since 2000 in OECD countries. Targeted grey literature, reference list, and citation searching was also carried out. Search results were downloaded to Microsoft Excel and screened by three reviewers according to pre-determined inclusion / exclusion criteria. Data from included studies, such as the type of activity noted within the paper, the population involved and the public health approach that was utilised, was extracted from within the paper using a data extraction form and narratively synthesised.

RESULTS

Fifty-two references were included in the final review (37 database searching; 9 reference list searching; 6 grey literature). Included articles were categorised according to the relevant public health domains and subdomains as articulated by the UK Faculty of Public Health: 1. Health improvement domain: Public health education and advice (Health promotion sub-domain) (n=13) Emergency Services personnel providing vaccines (Disease prevention sub-domain) (n=1) 2. Health care public health domain Paramedicine (Service delivery sub-domain) (n=30) Screening tools and referral pathways used by the ambulance sector (Service delivery sub-domain) (n=28) Health intelligence using ambulance sector data (population health management sub-domain) (n=26) Of note, some domains (e.g. health protection) returned nil results.

DISCUSSION

The scoping review demonstrates the breadth of public health related activities in which the ambulance sector is involved. However, an overemphasis on demand management outcomes precludes definitive conclusions on the impact of ambulance sector-led public health initiatives on public health outcomes. Future evaluations of public health initiatives should incorporate wider health system perspectives beyond the immediately apparent remit of the ambulance sector.

A Proposed Theoretical Framework for Clinical Judgment in EMS

In the prehospital setting, EMS clinicians are challenged by the need to assess and treat patients who are clinically undifferentiated with a large constellation of possible medical problems. In addition to possessing a large and diverse set of knowledge, skills, and abilities, EMS clinicians must integrate a plethora of environmental, patient, and event specific cues in their clinical decision-making processes. To date, there is no theoretical framework to capture the complex process that characterizes the prehospital experience from dispatch to handoff, the interface between cues and on-scene information and assessments, while incorporating the importance of leadership and communication. To fill this gap, we propose a theoretical framework for clinical judgment in the prehospital setting that builds upon previously defined methodologies and applies them to the clinical practice of EMS clinicians throughout the EMS experience.

Paramedics assessing patients with complex comorbidities in community settings: results from the CARPE study

Objectives

The aim for this study was to provide information about how community paramedicine home visit programs best “navigate” their role delivering preventative care to frequent 9-1-1 users by describing demographic and clinical characteristics of their patients and comparing them to existing community care populations.

Methods

Our study used secondary data from standardized assessment instruments used in the delivery of home care, community support services, and community paramedicine home visit programs in Ontario. Identical assessment items from each instrument enabled comparisons of demographic, clinical, and social characteristics of community-dwelling older adults using descriptive statistics and z-tests.

Results

Data were analyzed for 29,938 home care clients, 13,782 community support services clients, and 136 community paramedicine patients. Differences were observed in proportions of individuals living alone between community paramedicine patients versus home care clients and community support clients (47.8%, 33.8%, and 59.9% respectively). We found higher proportions of community paramedicine patients with multiple chronic disease (87%, compared to 63% and 42%) and mental health-related conditions (43.4%, compared to 26.2% and 18.8% for depression, as an example).

Conclusion

When using existing community care populations as a reference group, it appears that patients seen in community paramedicine home visit programs are a distinct sub-group of the community-dwelling older adult population with more complex comorbidities, possibly exacerbated by mental illness and social isolation from living alone. Community paramedicine programs may serve as a sentinel support opportunity for patients whose health conditions are not being addressed through timely access to other existing care providers.

Community nurse-paramedics' sphere of practice in primary care; an ethnographic study

Background

Primary care, the principal function of the health care system, requires effort from all local primary health care teams. Community Paramedicine (CP) has managed to reduce the use of Emergency Medical Services (EMS) for non-emergency calls, but for the paramedic to move from traditional emergency calls to non-emergency care will mean new demands. There is a paucity of research exploring nurse-paramedics’ experiences and perceptions of their novel roles as community paramedics in Finland. This study aims to explore the community nurse-paramedics’ (CNP) experiences in their new sphere of practice.

Methods

A descriptive ethnographic study was conducted, to collect data through participant observation (317 h total) and semi-structured interviews (N = 22) in three hospital districts (HD) where the CNPs have worked for at least 1 year. Both data sets were combined, organised, and analysed using inductive content analysis.

Results

Five main categories were developed by applying inductive content analysis: the new way of thinking, the broad group of patients, the way to provide care, the diversity of multidisciplinary collaboration, and tailored support from the organisation. The CNP was identified as needing an appropriate attitude towards care and a broader way of thinking compared to the traditional practice of taking care of the patient and the family members. The diversity of multidisciplinary collaboration teams can be a sensitive but worthwhile topic for offering new possibilities. Tailored support from the organisation includes tools for future CP models.

Conclusions

Our results indicate the CNPs’ deep involvement in patients’ and families’ care needs and challenges with their skills and competencies. Their professional attitudes and eagerness to develop and maintain multidisciplinary collaboration can offer preventive and long-term caring solutions from which citizens, allied health, safety, and social care providers benefit locally and globally.

New Horizons in Understanding Appropriate Prehospital Identification and Trauma Triage for Older Adults

Caring for older people is an important part of prehospital practice, including appropriate triage and transportation decisions. However, prehospital triage criteria are designed to predominantly assess injury severity or high-energy mechanism which is not the case for older people who often have injuries compounded by multimorbidity and frailty. This has led to high rates of under-triage in this population. This narrative review aimed to assess aspects other than triage criteria to better understand and improve prehospital triage decisions for older trauma patients. This includes integrating frailty assessment in prehospital trauma triage, which was shown to predict adverse outcomes for older trauma patients. Furthermore, determining appropriate outcome measures and the benefits of Major Trauma Centers (MTCs) for older trauma patients should be considered in order to direct accurate and more beneficial prehospital trauma triage decisions. It is still not clear what are the appropriate outcome measures that should be applied when caring for older trauma patients. There is also no strong consensus about the benefits of MTC access for older trauma patients with regards to survival, in-hospital length of stay, discharge disposition, and complications. Moreover, looking into factors other than triage criteria such as distance to MTCs, patient or relative choice, training, unfamiliarity with protocols, and possible ageism, which were shown to impact prehospital triage decisions but their impact on outcomes has not been investigated yet, should be more actively assessed and investigated for this population. Therefore, this paper aimed to discuss the available evidence around frailty assessment in prehospital care, appropriate outcome measures for older trauma patients, the benefits of MTC access for older patients, and factors other than triage criteria that could adversely impact accurate prehospital triage decisions for older trauma patients. It also provided several suggestions for the future.

Paramedics Have Untapped Potential to Address Social Determinants of Health in Canada

The role of paramedics, including select paramedics providing primary and preventive care in homes and community settings, is evolving in health systems around the world. These developments are associated with improvements in health outcomes, improved access to services and reduced emergency department use. Building on these existing trends in paramedicine, and because social conditions contribute to illness and are strong predictors of future health service use, addressing patients' social needs should be integrated into core paramedic practice in Canada. We discuss how paramedic education, culture and governance could better enable paramedics to address the social determinants of health.

Performance of the interRAI ED Screener for Risk-Screening in Older Adults Accessing Paramedic Services

Background

Paramedics respond to a significant number of non-emergency calls generated by older adults each year. Paramedics routinely assess and screen older adults to determine risk level and need for additional follow-up. This project implemented the interRAI ED Screener into routine care to determine whether the screener and resulting Assessment Urgency Algorithm (AUA) score is useful in predicting adverse outcomes.

Methods

We conducted a population-based retrospective study using administrative health data for patients aged 65+ assessed by paramedics from July 2016 to February 2017. Patients were assigned an AUA score and classified into three risk categories. Outcome data including hospitalizations, Emergency Department (ED) visits, home care status, and survival were collected and compared across AUA risk categories using descriptive and analytical statistics.

Results

Of the 2,801 patients screened, 31.9% were classified as high risk, 23.6% as moderate risk, and 44.6% as low risk. Patients who scored in the highest risk category were found to have longer hospital stays, and were more likely to require home care (p<.0001). The AUA risk category also predicted survival (p<.001).

Conclusions

The AUA predicted multiple adverse outcomes in this population. Use of the AUA by paramedics may aid in earlier identification of those in need of additional intervention and services.

The core components of Community Paramedicine - integrated care in primary care setting: a scoping review

BACKGROUND

Since the beginning of 2000, the primary healthcare services around the globe are challenged between demands of home care and number of staff delivering it. The delivery of healthcare needs new models to reduce the costs, patient's readmission and increase their possibilities to stay at home. Several paramedicine programmes have been developed to deliver home care as an integral part of the local healthcare system. The programmes varied in nature and the concept of Community Paramedicine (CP) has not been established, demanding clarity. The aim of this review was to identify and describe the core components of CP, and identify research gaps for the further study.

METHOD

A scoping review was performed using five electronic databases: Medline; CINAHL; Academic Search Premier; PubMed and the Cochrane Library for the period 2005 - June 2018. The references of articles were checked, and papers were assessed against inclusion criteria and appraised for quality.

RESULTS

From 803 initial articles, 21 met the criteria and were included. Inductive content analysis was carried out. The four core components of Community Paramedicine emerged (a) Community engagement, (b) Multi-agency collaboration, (c) Patient-centred prevention and (d) Outcomes of programme: cost-effectiveness and patients' experiences.

CONCLUSION

The Community Paramedicine programmes are perceived to be promising. However, Community Paramedicine research data are lacking. Further research is required to understand whether this novel model of healthcare is reducing costs, improving health and enhancing people's experiences.

Preventing emergency department (ED) visits and hospitalisations of older adults with cognitive impairment compared with the general senior population: what do we know about avoidable incidents? Results from a scoping review

OBJECTIVES

Older cognitively impaired adults present a higher risk of hospitalisation and mortality following a visit to the emergency department (ED). Better understanding of avoidable incidents is needed to prevent them and the associated ED presentations in community-dwelling adults. This study aimed to synthetise the actual knowledge concerning these incidents leading this population to ED presentation, as well as possible preventive measures to reduce them.

DESIGN

A scoping review was performed according to the Arksey and O'Malley framework.

METHODS

Scientific and grey literature published between 1996 and 2017 were examined in databases (Medline, Cumulative Index of Nursing and Allied Health, Ageline, Scopus, ProQuest Dissertations/theses, Evidence-based medecine (EBM) Reviews, Healthstar), online library catalogues, governmental websites and published statistics. Sources discussing avoidable incidents leading to ED presentations were included and then extended to those discussing hospitalisation and mortality due to a lack of sources. Data (type, frequency, severity and circumstances of incidents, preventive measures) was extracted using a thematic chart, then analysed with content analysis.

RESULTS

67 sources were included in this scoping review. Five types of avoidable incidents (falls, burns, transport accidents, harm due to self-negligence and due to wandering) emerged, and all but transport accidents were more frequent in cognitively impaired seniors. Differences regarding circumstances were only reported for burns, as scalding was the most prevalent mechanism of injury for this population compared with flames for the general senior population. Multifactorial interventions and implications of other professionals (eg, pharmacist, firefighters) were reported as potential interventions to reduce avoidable incidents. However, few preventive measures were specifically tested in this population.

CONCLUSIONS

Primary research that screens for cognitive impairment and involves actors (eg, paramedics) to improve our understanding of avoidable incidents leading to ED visits is greatly needed. This knowledge is essential to develop preventive measures tailored to the needs of older cognitively impaired adults.
