Is the case-mix of patients who self-present to ED similar to general practice and other acute-care facilities?

Patient presentations to an after-hours general practice, an urgent care clinic and an emergency department on Sundays: a comparative, observational study

PURPOSE

The purpose of this paper is to determine which factors are associated with 6,065 patient presentations with non-life-threatening urgent conditions (NLTUCs) to an after-hours general practice, an urgent care clinic (UCC) and an emergency department (ED) on Sundays in Southeast Queensland (Qld).

DESIGN/METHODOLOGY/APPROACH

A retrospective, comparative and observational study was conducted involving the auditing of medical records of patients with NLTUCs consulting three medical services between 0,800 and 1,700 h, on Sundays, over a one-year period. The study was limited to 6,065 patients.

FINDINGS

There were statistically significant differences in choice of location according to age, number of postcodes from the patient's residence, time of the day, season, patient presentations for infection and injury, non-infectious, non-injurious conditions of the circulatory, gastrointestinal and genitourinary systems, and need for imaging, pathology, plastering/back-slab application, splinting and wound closure. Older adults were more likely to be admitted to the hospital and Ed Short Stay Unit, compared with other age groups.

RESEARCH LIMITATIONS/IMPLICATIONS

Based on international models of UCC healthcare systems in United Kingdom (UK), USA and New Zealand (NZ) and the results of this study, it is recommended that UCCs in Australia have extended hours, walk-in availability, access to on-site radiology, ability to treat fractures and wounds and staffing by medical practitioners able to manage these conditions. Recommendations also include setting a national standard for UCC operation (National Urgent Care Centre Accreditation, 2018; NHS, 2020; RNZCUC, 2015) and requirements for vocational registration for medical practitioners (National Urgent Care Centre Accreditation, 2018; RNZCUC, 2015; The Royal College of Surgeons of Edinburgh, 2021a, b).

PRACTICAL IMPLICATIONS

This study has highlighted three key areas for future research: first, research involving general practitioners (GPs), emergency physicians, urgent care physicians, nurse practitioners, urgent care pharmacists and paramedics could help to predict the type of patients more accurately, patient presentations and associated comorbidities that might be encouraged to attend or be diverted to Urgent Care Clinics. Second, larger studies of more facilities and more patients could improve the accuracy and generalisability of the findings. Lastly, studies of public health messaging need to be undertaken to determine how best to encourage patients with NLTUCs (especially infections and injuries) to present to UCCs.

SOCIAL IMPLICATIONS

The Urgent Care Clinic model has existed in developed countries since 1973. The adoption of this model in Australia close to a patient's home, open extended hours and with onsite radiology could provide a community option, to ED, for NLTUCs (especially patient presentations with infections and injuries).

ORIGINALITY/VALUE

This study reviewed three types of medical facilities for the management of NLTUCs. They were an after-hours general practice, an urgent care clinic and an emergency department. This study found that the patient choice of destination depends on the ability of the service to manage their NLTUCs, patient age, type of condition, postcodes lived away from the facility, availability of testing and provision of consumables. This study also provides recommendations for the development of an urgent care healthcare system in Australia based on international models and includes requirements for extended hours, walk-in availability, radiology on-site, national standard and national requirements for vocational registration for medical professionals.

What do we know about demand, use and outcomes in primary care out-of-hours services? A systematic scoping review of international literature

OBJECTIVE

To synthesise international evidence for demand, use and outcomes of primary care out-of-hours health services (OOHS).

DESIGN

Systematic scoping review.

DATA SOURCES

CINAHL; Medline; PsyARTICLES; PsycINFO; SocINDEX; and Embase from 1995 to 2019.

STUDY SELECTION

English language studies in UK or similar international settings, focused on services in or directly impacting primary care.

RESULTS

105 studies included: 54% from mainland Europe/Republic of Ireland; 37% from UK. Most focused on general practitioner-led out-of-hours cooperatives. Evidence for increasing patient demand over time was weak due to data heterogeneity, infrequent reporting of population denominators and little adjustment for population sociodemographics. There was consistent evidence of higher OOHS use in the evening compared with overnight, at weekends and by certain groups (children aged <5, adults aged >65, women, those from socioeconomically deprived areas, with chronic diseases or mental health problems). Contact with OOHS was driven by problems perceived as urgent by patients. Respiratory, musculoskeletal, skin and abdominal symptoms were the most common reasons for contact in adults; fever and gastrointestinal symptoms were the most common in the under-5s. Frequent users of daytime services were also frequent OOHS users; difficulty accessing daytime services was also associated with OOHS use. There is some evidence to suggest that OOHS colocated in emergency departments (ED) can reduce demand in EDs.

CONCLUSIONS

Policy changes have impacted on OOHS over the past two decades. While there are generalisable lessons, a lack of comparable data makes it difficult to judge how demand has changed over time. Agreement on collection of OOHS data would allow robust comparisons within and across countries and across new models of care. Future developments in OOHS should also pay more attention to the relationship with daytime primary care and other services.

Cardiac Myosin-Binding Protein C-From Bench to Improved Diagnosis of Acute Myocardial Infarction

Chest pain is responsible for 6-10% of all presentations to acute healthcare providers. Triage is inherently difficult and heavily reliant on the quantification of cardiac Troponin (cTn), as a minority of patients with an ultimate diagnosis of acute myocardial infarction (AMI) present with clear diagnostic features such as ST-elevation on the electrocardiogram. Owing to slow release and disappearance of cTn, many patients require repeat blood testing or present with stable but elevated concentrations of the best available biomarker and are thus caught at the interplay of sensitivity and specificity.We identified cardiac myosin-binding protein C (cMyC) in coronary venous effluent and developed a high-sensitivity assay by producing an array of monoclonal antibodies and choosing an ideal pair based on affinity and epitope maps. Compared to high-sensitivity cardiac Troponin (hs-cTn), we demonstrated that cMyC appears earlier and rises faster following myocardial necrosis. In this review, we discuss discovery and structure of cMyC, as well as the migration from a comparably insensitive to a high-sensitivity assay facilitating first clinical studies. This assay was subsequently used to describe relative abundance of the protein, compare sensitivity to two high-sensitivity cTn assays and test diagnostic performance in over 1900 patients presenting with chest pain and suspected AMI. A standout feature was cMyC's ability to more effectively triage patients. This distinction is likely related to the documented greater abundance and more rapid release profile, which could significantly improve the early triage of patients with suspected AMI.

Measuring Emergency Department Acuity

BACKGROUND

Emergency department (ED) acuity is the general level of patient illness, urgency for clinical intervention, and intensity of resource use in an ED environment. The relative strength of commonly used measures of ED acuity is not well understood.

METHODS

We performed a retrospective cross-sectional analysis of ED-level data to evaluate the relative strength of association between commonly used proxy measures with a full spectrum measure of ED acuity. Common measures included the percentage of patients with Emergency Severity Index (ESI) scores of 1 or 2, case mix index (CMI), academic status, annual ED volume, inpatient admission rate, percentage of Medicare patients, and patients seen per attending-hour. Our reference standard for acuity is the proportion of high-acuity charts (PHAC) coded and billed according to the Centers for Medicare and Medicaid Service's Ambulatory Payment Classification (APC) system. High-acuity charts included those APC 4 or 5 or critical care. PHAC was represented as a fractional response variable. We examined the strength of associations between common acuity measures and PHAC using Spearman's rank correlation coefficients (r_s ) and regression models including a quasi-binomial generalized linear model and linear regression.

RESULTS

In our univariate analysis, the percentage of patients ESI 1 or 2, CMI, academic status, and annual ED volume had statistically significant associations with PHAC. None explained more than 16% of PHAC variation. For regression models including all common acuity measures, academic status was the only variable significantly associated with PHAC.

CONCLUSION

Emergency Severity Index had the strongest association with PHAC followed by CMI and annual ED volume. Academic status captures variability outside of that explained by ESI, CMI, annual ED volume, percentage of Medicare patients, or patients per attending per hour. All measures combined only explained only 42.6% of PHAC variation.

"They Shouldn't Be Coming to the ED, Should They?": A Descriptive Service Evaluation of Why Patients With Palliative Care Needs Present to the Emergency Department

BACKGROUND

Patients with palliative care needs frequently attend the emergency department (ED). There is no international agreement on which patients are best cared for in the ED, compared to the primary care setting or direct admission to the hospital. This article presents the quantitative phase of a mixed-methods service evaluation, exploring the reasons why patients with palliative care needs present to the ED.

METHODS

This is a single-center, observational study including all patients under the care of a specialist palliative care team who presented to the ED over a 10-week period. Demographic and clinical data were collected from electronic health records.

RESULTS

A total of 105 patients made 112 presentations to the ED. The 2 most common presenting complaints were shortness of breath (35%) and pain (28%). Eighty-three percent of presentations required care in the ED according to a priori defined criteria. They either underwent urgent investigation or received immediate interventions that could not be delivered in another setting, were referred by a health-care professional, or were admitted.

CONCLUSIONS

Findings challenge the misconception that patients known to a palliative care team should be cared for outside the ED. The importance and necessity of the ED for patients in their last years of life has been highlighted, specifically in terms of managing acute, unpredictable crises. Future service provision should not be based solely on a patient's presenting complaint. Further qualitative research exploring patient perspective is required in order to explore the decision-making process that leads patients with palliative care needs to the ED.

'They shouldn't be coming to the ED, should they?' A qualitative study of why patients with palliative care needs present to the emergency department

INTRODUCTION

Across the developed world, there are concerns about 'inappropriate' use of the emergency department (ED). Patients with palliative care needs frequently attend the ED. Previous studies define the 'reason' for presentation as the 'presenting symptom', which ignores the perspectives of service users. This paper addresses an acknowledged gap in the literature, which fails to examine the decision-making process that brings patients to the ED.

METHODS

In-depth narrative interviews were conducted with 7 patients (known to a specialist palliative care service and presenting to the ED during a 10-week period) and 2 informal caregivers. Analysis drew on 'Burden of Treatment Theory' to examine the meaning attributed by participants to their experience of serious acute illness, their capacity for action and the work required to access emergency care.

RESULTS

5 themes were identified about how and why emergency services were accessed: capacity for action, making sense of local services, making decisions to access emergency services, experience of emergency care and coping with change. All narratives captured concerns surrounding the complexity of services. Participants struggled to piece together the jigsaw of services, and were subsequently more likely to attend the ED. Differences between the ways that patients with chronic obstructive pulmonary disease and cancer accessed the ED were prominent.

CONCLUSIONS

Further work is needed to understand and respond to decisions leading patients with palliative care needs to the ED, particularly in the context of locally fragmented services, poor signposting and confusion about available healthcare. The perspectives of service users are essential in shaping emergency care.
