This study focusses on patients with coronary artery disease (CAD) and peripheral artery disease (PAD). The aim of the study is to estimate how frequent each of these conditions are in England, what issues and challenges patients with these conditions frequently face, and how much it costs the National health Service to treat patients with these conditions. We will also look at the implications on patients of these three disorders who also suffer from other diseases such as diabetes or who have had a heart attack in the past.
This is a cohort study with the overall objective of gaining a better understanding of the epidemiology, disease course, health resource utilisation (HRU), and treatment patterns of real-world patients with coronary artery disease (CAD), peripheral artery disease (PAD), and patients with CAD or PAD. The specific aims of the study are:
- To estimate the incidence and prevalence of CAD, PAD, and CAD or PAD
- To describe demographic and clinical characteristics of patients with CAD, PAD, and CAD or PAD
- To estimate the risk/incidence of complications (e.g. major cardiovascular events, bleeding) among patients with CAD, PAD, and CAD or PAD
- To describe HRU related to CAD and PAD complications among patients with CAD, PAD and CAD or PAD
- To describe treatment patterns, with a focus on standard of care, among patients with CAD, PAD, and CAD or PAD
- To estimate the risk/incidence of complications, compare the risk of complications, describe HRU related to CAD and PAD complications, and describe treatment patterns among subgroups of patients with CAD, PAD, and CAD or PAD defined by demographics, medical history, prior procedures, medication use, and risk scores.
The study will be undertaken utilizing linked data within the Clinical Practice Research Database and Hospital Episode Statistics database. The study time frame will be 1, January 2006 to December 31st, 2016
