Cardiovascular disease and prediabetes as complex illness: People's perspectives

Cardiovascular disease (CVD) and sustained high blood glucose as prediabetes are an established comorbidity. People's experience in reconciling these long-term conditions requires deeper appreciation if nurses are to more effectively support person-centred care for people who have them. Our analysis explores the initial experience of people admitted to hospital with CVD who then find they also have sustained high blood glucose. Our methodology is informed by the philosophy of Gadamer and applies interpretive description to develop an interpretation of participant experiences. The major theme emerging from participant interviews was the 'invisible disequilibrium' characterised by three subthemes: 'losing equilibrium', 'becoming embattled' and 'evolving illness'. This study examines CVD and prediabetes in conjunction with the Gadamerian notion of the 'whole', as being in a social and emotional world in which illness is also a component part. We explore how participants lived within an 'invisible disequilibrium', with prediabetes frequently remaining unnoticed, while CVD was manifest. To identify multiple conditions and support effective intervention to manage them as part of person-centric care, nursing practice should explore the 'whole' of the person's experience, value people's knowledge as potential indicators of complex illness, thereby reducing the risk of accelerating complex illness.
