GOVERNANCE BOARD 14th January 2014 Clinical Audit of Stroke Services At Shrewsbury and Telford Hospitals NHS Trust 1.0 Introduction A clinical review of cases recorded and coded as with a 0-1 day length of stay was carried out at Shrewsbury and Telford Hospitals on 4 th December 2013 by Dr Jo Leahy and Christine Morris, Executive Nurse. 2.0 Background In reports from the Chief Finance Officer previously to the Board it has been reported that there has been significant growth in this area in the past 12 months and the aim of the audit was to explore the context for this, aligned to the clinical pathway in place in the Hospital Trust. (Appendix 1) 3.0 Audit process The reviewers used the simple audit tool shown in appendix 2 and reviewed 35 of the 38 sets of case notes coded as with a 0-1 day length of stay during the period 1 st may 2013 31 st August 2013. (The two remaining sets of notes belonged to 2 current inpatients.) Inclusion criteria was based on there being a primary diagnosis of there is a zero or 1 day length of stay the place of discharge is either home or Other Provider General Ward Of these 38 cases, 34 were coded as Stroke Best Practice Tariff. 4.0 Audit Findings The findings of the review are detailed in appendix 3. However, throughout review of the 35 sets of cases notes a number of themes were evident: the term Transient Ischaemic Attack (TIA) was not in use within the case notes for this cohort of patients. Some patients were given diagnosis of based on clinician s findings and not confirmed through diagnostic investigations. Some cases were coded as when they were not e.g. UTI, chronic exacerbation of a long term condition, previous. 1 P a g e
2 cases were immediately transferred to specialist units for care and not treated in SATH The pathway was considered excellent for patients with evidence of all having rapid access to multi -disciplinary team reviews and diagnostics. Royal College of Physicians national clinical guidance for can be found at: http://www.rcplondon.ac.uk/sites/default/files/national-clinical-guidelines-for--fourthedition.pdf. The guidance is informative and demonstrates that the pathway in place at SATH is aligned to best practice. All patients whose acute symptoms and signs resolve within 24 hours (ie TIA) should be seen by a specialist in neurovascular disease (eg in a specialist neurovascular clinic or an acute unit). 4.2.1A pxiii Transient ischaemic attack (TIA) is traditionally defined as an acute loss of focal cerebral or ocular function with symptoms lasting less than 24 hours and which is thought to be due to inadequate cerebral or ocular blood supply as a result of low blood flow, thrombosis or embolism associated with diseases of the blood vessels, heart, or blood (Hankey and Warlow 1994). A definition more recently suggested is: an event lasting less than 1 hour without cerebral infarction on a magnetic resonance imaging brain scan, but this requires early scanning. In practice the precise definitions used are not of great importance as however quickly or slowly recovery occurs and whether or not there is evidence of neuronal damage on brain imaging, the investigations and medical treatment will be broadly similar. All cerebrovascular events need to be taken seriously and treated with urgency. TIAs affect 35 people per 100,000 of the population each year and are associated with a very high risk of in the first month after the event and up to 1year p4 This raises the question what clinical presentation does the trust code as TIA and what is classified as a? Feedback in relation to the clinical pathway has been given to the Clinical leaders within the Trust. 5.0 Recommendations The reviewers would recommend that series of formal questions are posed the Trust via the contractual process to gain an understanding into the question above before considering next steps by the Chief Finance Officer. The CCG would want clarified what presentation does the Trust consider to be categorised as a TIA and what is a? Why were some cases coded as when they were not proven to be so? Why were cases immediately transferred to other centers (UHNS) coded as? Is there 24/7 7 day access to diagnostic investigations and thrombolysis? Dr Jo Leahy GP Board Member.
