Implementation of the updated NICE haematological cancers (NG47) improving outcomes guidelines across Specialist Integrated Haematological Malignancy Diagnostic Services (SIHMDS) in England: a UK NEQAS LI survey.

Aims: Haematological malignancies represent a diverse group of diseases with complex diagnostic requirements. National Institute for Health and Care Excellence (NICE) Haematological Cancer: Improving Outcomes Guidance was published in 2003 and updated in 2016 (NG47), providing recommendations for service delivery including Specialist Integrated Haematological Malignancy Diagnostic Services (SIHMDSs). This survey assessed the implementation of NG47 guidelines, with a specific focus on implementation in relation to laboratory SIHMDS delivery.

Methods: A survey was issued to the 17 SIHMDSs identified in England. The questionnaire covered laboratory configuration, information systems, integrated reporting and multidisciplinary team (MDT) working recommendations.

Results: In the 10 responding SIHMDS, full implementation of recommendations was not achieved. Higher levels of implementation were reported in 'colocated' services compared with 'networked' SIHMDS. Increased guideline implementation was reported with longer duration since initial establishment of a SIHMDS and for laboratory based as opposed to clinical (MDT) reporting recommendations.

Conclusions: Our survey highlights variable implementation of NICE guidance across SIHMDS, with likely inequity of access, standardisation and quality in haemato-oncology diagnostics. Provision of a more structured framework for guideline implementation could assist in increasing compliance to meet the goals of quality and equity of access to harmonised haemato-oncology diagnostics across the NHS in England. This would provide a basis for evaluating the clinical benefits and health economic impact of the SIHMDS model on patient care and outcomes.
