Impact of multimorbidity and complex multimorbidity on healthcare utilisation in older Australian adults aged 45 years or more: a large population-based cross-sectional data linkage study.

ABSTRACT:

Objectives

As life expectancy increases, older people are living longer with multimorbidity (MM, co-occurrence of ≥2 chronic health conditions) and complex multimorbidity (CMM, ≥3 chronic conditions affecting ≥3 different body systems). We assessed the impacts of MM and CMM on healthcare service use in Australia, as little was known about this.

Design

Population-based cross-sectional data linkage study.

Setting

New South Wales, Australia.

Participants

248 496 people aged ≥45 years who completed the Sax Institute's 45 and Up Study baseline questionnaire.

Primary outcome
