Abstract

Background & aims: Large, population-based studies that have included the full spectrum of cirrhosis estimating survival, taking into account time-at-risk are lacking. We aimed to report 1- and 5-year average survival rates for people with cirrhosis to be used in a clinical and healthcare policy setting.

Methods: We used the Clinical Practice Research Datalink and linked English Hospital Episode Statistics to identify adult cases of cirrhosis from January 1998 to December 2009. We estimated 1- and 5-year survival according to whether time-at-risk was ambulatory or followed an emergency hospital admission related to liver disease, stratified by age, sex, and aetiology to be used in a clinical setting. We used a multivariate Cox-proportional hazards model with a time-varying variable, adjusted for Baveno IV stage of cirrhosis at diagnosis, age, aetiology, and sex.

Results: We identified 5118 incident cases. Average survival probabilities at 1- and 5-years were 0.84 (95% CI 0.83-0.86) and 0.66 (95% CI 0.63-0.68) for the ambulatory group and 0.55 (95% CI 0.53-0.57) and 0.31 (95% CI 0.29-0.33) following hospitalisation, respectively. A hospital admission at diagnosis or subsequently for liver disease substantially impaired prognosis independent of stage of cirrhosis (HR=2.78, 95% CI 2.53, 3.06).

Conclusions: Emergency hospitalisation for liver disease heralds a downturn in a patient's outlook independent of their stage of cirrhosis. Our results provide population-based clinically translatable estimates of prognosis for the purposes of healthcare delivery and planning and communication to patients.
