Exeter Collaboration for Academic Primary Care (APEx)

Long-term conditions

The Long-Term Conditions (LTC) theme encompasses research into all chronic conditions for which there is currently no cure, and which are managed with medications and other treatments in primary care, including both physical and mental health conditions. Particular areas of focus are cardiovascular disease, diabetes, and asthma/COPD, as well as multi-morbidity, and frailty and diseases of ageing.

 

Our vision is to deliver world-leading, impactful research programmes into all aspects of detection, diagnosis, care and prognosis of long-term conditions, resulting in improved health and care.

 

The theme brings together LTC researchers from across APEx, with expertise in a wide range of methodologies, including clinical trials, epidemiology and data science, qualitative methods, and evidence synthesis.

Aims

  • To address all aspects of chronic disease management including detection (e.g. risk stratification, clinical methods), diagnosis (e.g. new diagnostic tools), care (e.g. doctor-patient communication, non-drug interventions), and prognosis (e.g. prediction tools)
  • To improve health and care for people living with LTCs
  • To share expertise across methodologies and clinical topics
  • To prioritise research topics, co-ordinate responses to future research calls, and offer shared opportunities to enhance future funding bids
  • To support career development
