National Cancer Diagnosis Audit: initial results on avoidable delays

Background An earlier diagnosis of cancer can increase cancer survival and quality of life. Characterising avoidable delays to a patient’s diagnosis of cancer can help to direct quality improvement initiatives. Aim To evaluate avoidable delays to cancer diagnoses and the variation by cancer type and patient characteristics using primary care data collected as part of the National Cancer Diagnosis Audit (NCDA). Method English general practices participating in the NCDA (439) entered primary care data on patients (17,042) diagnosed with cancer in 2014. Using a taxonomy developed from the National Audit of Cancer Diagnosis in Primary Care (2011), GPs reported delays to the diagnosis that in their judgement were avoidable. Results In 22% of NCDA patient records (n = 3380), the GP considered there to be an avoidable delay to the patient receiving their cancer diagnosis. There was variation by cancer type; 7% of breast cancer patients experienced delays compared to 34% of stomach cancer patients. 49% of avoidable delays occurred in primary care and 38% in secondary or tertiary care. Of all delays, 28% were attributed to clinician factors and 34% to health care system factors. Results will be presented by patient characteristics. Conclusion Primary care data from the NCDA can be used to better understand potentially avoidable delays to diagnosis and identify possible solutions for improving the diagnostic pathway. Avoidable delays during cancer diagnosis occur for many reasons. These insights can inform quality improvement initiatives, which should be directed at both clinical and organisational factors in primary care and hospital settings.
