Implementation of a cauda equina service in a medium-sized district general hospital in the UK

A novel approach to expedite emergency investigation for suspected cauda equina syndrome referrals from community and primary care services: A service evaluation

INTRODUCTION

Although a rare spinal emergency, cauda equina syndrome (CES) can result in significant physical, emotional, and psychological sequalae. Introducing a CES pathway enhances diagnosis but may increase Radiology and Orthopaedic workload. To address this, one NHS hospital in England introduced a novel CES pathway. Utilising a criteria-led pathway, patients were referred directly from community/primary care, via the Emergency Department, for an emergency MRI scan.

OBJECTIVE

To compare the outcomes of patients referred via an original and redesigned Community and Primary Care CES pathway.

DESIGN

A retrospective service evaluation was undertaken of all emergency MRI scans investigating suspected CES via either pathway.

METHODS

Two 3-month time periods were analysed; pre-(original) and post-implementation of the redesigned pathway; time to surgery was reviewed over two 12-month periods.

RESULTS

Increased MRI scan utilisation was seen following the implementation of the redesigned pathway: original n = 50, redesigned n = 128, increasing Radiology workload. However, the redesigned pathway resulted in a reduction in time to MRI from 3h:01m to 1h:02m; reduction in time spent in ED 4h:55m to 3h:24m; reduction in time to surgery 18h:05m to 13h:38m; reduction in out-of-hour scanning from 10 to 2 patients during the evaluation period; and a reduction in on-call Orthopaedic involvement by 38%.

CONCLUSION

All timed outcomes were improved with the implementation of this novel pathway. This suggests expediting MRI scans can result in substantial downstream benefits; albeit while increasing MRI scan utilisation. This pathway aligns with the emergency management of suspected CES under the new national CES pathway in England.

Early experience of a local pathway on the waiting time for MRI in patients presenting to a UK district general hospital with suspected cauda equina syndrome

AIM

This study evaluated the impact of the Salisbury Protocol for Assessment of Cauda Equina Syndrome (SPACES) on the waiting time for MRI in patients presenting with suspected Cauda Equina Syndrome (sCES) within a UK district general hospital.

PATIENTS AND METHODS

All consecutive patients undergoing an MRI scan in our hospital, for sCES, over a 12 month period, prior to and following the introduction of SPACES, were identified. Patient's gender, age, MRI diagnosis, time from MRI request to imaging and outcome were recorded.

RESULTS

In the year prior to the introduction of SPACES, 66 patients underwent MRI for sCES, out of which 10.6% had cauda equina compression (CEC), 63.5% had other spinal pathology and 25% had a normal scan. In the year after introduction of SPACES, 160 patients underwent MRI for sCES out of which 6.2% had CEC, 70.7% had other spinal pathology and 23% had a normal scan. Despite the referrals for sCES increasing by more than 2-fold following the introduction of SPACES, the median time from MRI request to scan decreased from 9.1 to 4.2 hours (p = 0.106, Mann-Whitney-U) and the number of patients transferred to the regional hub hospital decreased from 7 to 3.

CONCLUSION

Implementation of SPACES for patients with sCES resulted in a substantial reduction in waiting time for MRI and decreased the number of transfers to the regional hub hospital. Based on our early experience, we encourage other centres within the UK to introduce such a pathway locally, to improve the management of patients with sCES.

A service evaluation of the management of patients with suspected cauda equina syndrome from an outpatient physiotherapy service in the United Kingdom

BACKGROUND

The expanding scope of physiotherapists worldwide has come with an increased responsibility to identify serious pathologies such as fracture, infection, tumour and cauda equina syndrome (CES). Guidelines recommend a low threshold for emergency MRI to avoid the potentially devastating consequences of CES, but a balanced approach is required to prevent excessive strain on emergency resources.

AIM

To evaluate the management of patients presenting to an outpatient physiotherapy service with suspected cauda equina syndrome.

DESIGN

Service evaluation with an embedded case series of patients with radiological CES.

METHOD

The records of patients who were identified by their outpatient physiotherapists as having suspected CES (n-231) over a 27-month period were included. Data was extracted from patients' medical records by a team of Advanced Clinical Practitioners (ACPs). The lead author further analysed the records of patients with clinical and radiological CES, in order to present the embedded case series.

RESULTS

In 79% of cases, it was decided that emergency referral was not required. The remaining 21% of patients were referred to the emergency department and 49% of these had an emergency MRI. In the case series of seven patients with cauda equina compression on MRI, four patients had a disc bulge and underwent emergency surgery. One patient had non-emergency surgery for a disc bulge combined with anterolisthesis and scoliosis. Two patients had stenosis and decided against surgical intervention.

CONCLUSIONS

Findings from this service evaluation suggest support for the use of safety netting and an effective communication chain to facilitate effective management of patients with suspected CES.
