Heart failure signs and symptoms, hospital referrals, and prescription patterns in patients receiving sacubitril/valsartan in primary care and cardiologist settings in Germany

Abstract

Aims The aim of this paper was to analyse heart failure (HF) signs and symptoms, hospital referrals, and prescription patterns in patients receiving sacubitril/valsartan (sac/val) in primary care and cardiology settings in Germany. Methods and results A retrospective cohort study of electronic medical records identified 1263 adults (aged >= 18 years) in the German IMS (R) Disease Analyzer database who were prescribed sac/val during 2016 and had at least 6 months of data following sac/val initiation. Clinical characteristics were collected during the 12 months before the first recorded sac/val prescription (index date) and 6 months post-index. Details of sac/val dose and prescription patterns were also recorded in the 6 months post-index. HF signs, symptoms, and all-cause hospital referrals were evaluated for 90 days pre-index and 30-120 days post-index. Most patients (62%) were prescribed the lowest sac/val dose of 24/26 mg twice daily (b.i.d.) at index; only 14% of patients initiated on 24/26 mg or 49/51 mg b.i.d. were up-titrated to the 97/103 mg b.i.d. target dose during the 6 months post-index, while 6% of patients initiated on either 49/51 mg or 97/103 mg b.i.d. were stably down-titrated. Evaluation of prescription patterns in relation to clinical characteristics did not clearly explain the reluctance to up-titrate in the majority of patients. More patients experienced HF signs or symptoms or all-cause referrals to hospital during the 90 days pre-index than during the 30-120 days post-index. Conclusions The majority of patients receiving sac/val are not up-titrated, contrary to recommendations of the EU summary of product characteristics; this is not fully explained by patients' clinical characteristics. Further research is required to understand the reasons for clinician inertia.
