Clinical outcomes when applying NICE guidance for the investigation of recent-onset chest pain to a rapid-access chest pain clinic population.

OBJECTIVE: To describe the clinical outcomes of patients for whom National Institute for Health and Care Excellence (NICE) recent-onset chest pain guidance would not have recommended further investigation, compared with those of patients where further investigation would have been recommended. METHODS: 557 consecutive patients with recent-onset chest pain attending rapid-access chest pain clinics (RACPC) in two district general hospitals over a 9-month period were retrospectively reviewed. Likelihood of coronary artery disease (CAD) was calculated according to NICE-defined modified Diamond-Forrester criteria. Patients were categorised into those for whom NICE guidelines recommend (NICE-Y) and do not recommend (NICE-N) further investigation. Main outcome measures were subsequent diagnosis of significant CAD and major adverse cardiac events (MACE) at 6 months. RESULTS: 187/557 (33.6%) patients comprised NICE-Y group, with 370/557 (66.4%) in NICE-N group. 360/370 (97.3%) of NICE-N group would have been excluded from further investigation due to non-anginal chest pain. Of 92/557 (16.5%) patients subsequently diagnosed with significant CAD, 35/557 (9.5%) were from NICE-N group versus 57/557 (30.5%, p<0.0001) from NICE-Y group. Of 11 patients experiencing at least one MACE, 7/557 (1.9%) were from NICE-N group, versus 4/557 (2.1%, p=1.000) from NICE-Y group. CONCLUSIONS: The rigid application of NICE chest pain guidance to a RACPC population may result in up to two-thirds of patients being excluded from further cardiac investigation. Potentially, up to 10% of these patients may subsequently be diagnosed with significant CAD, with up to 2% potentially experiencing a major adverse cardiac event.

Indications and interventional options for non-resectable tracheal stenosis.

Non-specific presentation and normal examination findings in early disease often result in tracheal obstruction being overlooked as a diagnosis until patients present acutely. Once diagnosed, surgical options should be considered, but often patient co-morbidity necessitates other interventional options. Non-resectable tracheal stenosis can be successfully managed by interventional bronchoscopy, with therapeutic options including airway dilatation, local tissue destruction and airway stenting. There are common aspects to the management of tracheal obstruction, tracheomalacia and tracheal fistulae. This paper reviews the pathogenesis, presentation, investigation and management of tracheal disease, with a focus on tracheal obstruction and the role of endotracheal intervention in management.
