Limited evidence for screening for serious pathologies using red flags in patients with low back pain presenting to the emergency department

Utilisation and experience of emergency medical services by patients with back pain: A scoping review

BACKGROUND

Back pain is recognised as a common reason for people to access emergency medical services (EMS). EMS focus on identifying and treating serious and life-threatening conditions. Back pain frequently has a non-specific cause, however back pain is also a symptom for potentially serious pathology best suited for management by EMS.

OBJECTIVES

This scoping review explores how and why patients with back pain access EMS, the care provided, and patients' and clinicians' perceptions of EMS.

METHODS

The established methodology advocated by the Joanna Briggs Institute was followed. Literature was identified via a comprehensive search of six databases as well as grey literature searching. Data was extracted to form a narrative review supported by summary tables and figures.

RESULTS

The review included 144 papers across the last 36 years, with half the papers published since 2018, the majority from the USA and Australia. Rates of back pain presentation range from 1 to 9% depending on the definition used, with the rate of serious pathology higher than in primary care. Patients present due to concerns about their condition, positive perceptions of the care provided by EMS and difficulty in accessing primary care. Imaging and opioids are widely used, blood markers may aid diagnosis of serious pathology, whilst physiotherapists in Emergency Departments may support management of patients without serious pathology.

CONCLUSIONS

Back pain is a common reason for EMS presentation. Whilst non-specific back pain is the most common diagnosis further research to support the recognition and care of serious cases would be beneficial.

A Model of Triage of Serious Spinal Pathologies and Therapeutic Options Based on a Delphi Study

Background and Objectives: The relevance of red flags in serious spinal pathology (SSP) has evolved throughout the last years. Recently, new considerations have been proposed to expand the consideration of red flags. The purpose of this study was to determine, approve and test a model for the triage and management process of SSPs based on the latest data available in the literature. Materials and Methods: The SSP model was initially built on the basis of a literature review. The model was further determined and approved by an expert panel using a Delphi process. Finally, clinical scenarios were used to test the applicability of the model. Results: After three rounds of the Delphi process, panellists reached a consensus on a final version of the model. The use of clinical scenarios by experts brought about reflexive elements both for the determined model and for the SSPs depicted in the clinical cases. Conclusions: The validation of the model and its implementation in the clinical field could help assess the skills of first-line practitioners managing spinal pain patients. To this end, the development of additional clinical scenarios fitting the determined model should be further considered.

A Quick and Comprehensive Guide to Differential Diagnosis of Neck and Back Pain: a Narrative Review

The list of diagnostic options when approaching a patient with axial pain is impressively complex. Many offer limited diagnostic workups, but we could not find a truly comprehensive diagnostic guide to assist in the diagnostic evaluation. In this short paper, we briefly described a long list of medical conditions, each of which can manifest as back or neck pain, and whose prevalence ranges from common to very rare. We then proposed an algorithm for classifying them into subgroups. Further referral to diagnostic tests and specialist consultations, after assignment to one of those subgroups, could save time and unnecessary tests. We believe that this review and the proposed diagnostic algorithm can be valuable for medical education and for use in the primary care setting for the diagnostic evaluation of any type of back or neck pain in all patient groups.
