Clinical nurse specialists and survival in patients with cancer: the UK National Cancer Experience Survey

Objective: To examine whether having a better care experience with a clinical nurse specialist (CNS) is associated with better overall survival of patients with cancer in England. Methods: We identified 99 371 patients with colorectal, lung, breast and prostate cancer who reported their care experience with CNS from the National Cancer Patient Experience Survey (2010-2014) and English cancer registration linked dataset. We categorised patients' experiences into three groups (excellent, non-excellent and no CNS name was given), across three aspects of CNS care: the ease of contacting their CNS, feeling that a CNS had listened to them and the degree to which explanations given by a CNS were understandable. We used univariable and multivariable Cox proportional hazards regression analyses to estimate HRs with 95% CIs by patient experience for each cancer adjusting for patients' sociodemographic and disease stage at diagnosis. Results: Among the three compared groups, patients who reported not being given a CNS name had the lowest survival. In the adjusted Cox regression analysis, the results show that among those who reported not being given a CNS name, the highest risk of death was in those with colorectal, breast and prostate cancers only (colorectal HR: 1.40; 95% CI: 1.32 to 1.84; breast HR: 1.34; 95% CI: 1.25 to 1.44; prostate HR: 1.09; 95% CI: 0.99 to 1.13). However, this association seemed reversed among patients with lung cancer, although attenuated when accounting for potential confounders. Conclusion: These findings provide new evidence of the vital contribution CNS may make to cancer survival and suggest CNS input and support should be available to all patients after the diagnosis.
