Validated methods to identify patients with asthma-COPD overlap in healthcare databases: a systematic review protocol.

ABSTRACT:

Introduction

Asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) is characterised by patients presenting symptoms of both asthma and COPD. Many efforts have been made to validate different methods of identifying asthma-COPD overlap cases based on symptoms, spirometry and medical history in epidemiological studies using healthcare databases. There are various coding algorithm strategies that can be used and selection depends on targeted validation. The primary objectives of this systematic review are to identify validated methods (or algorithms) that identify patients with ACO from healthcare databases and summarise the reported validity measures of these methods.

Methods

MEDLINE, EMBASE databases and the Web of Science will be systematically searched by using a
