COPD Treatment Pathway Establish diagnosis of COPD in at risk population with history, examination and spirometry (FEV 1 /FEV ratio <70%) Establish severity of disease by FEV 1 as % predicted Management of RISK FACTORS plus EDUCATION plus IMMUNISATION Pulmonary rehabilitation if functionally disabled – (Ensure treatment is optimised) SMOKING CESSATION Lifestyle Advice Diet/Exercise Influenza vax (annual) Pneumococcal vax.

Telemonitoring in COPD – the evidence base Numerous pilot projects with accompanying evaluation reports; – Often exceptionally good results (e.g. COPD telehealth in SE Essex – 75% reduction in A&E attendances; 83% reduction in hospital admissions) – Often methodologically limited (e.g. before-and-after studies; small sample sizes) Systematic reviews demonstrate that high-quality evidence base is still immature; – Bolton (2010): studies included were positive but of a low- quality – Polisena (2010): Telehealth interventions improved QoL and reduced hospitalisations

Best health, best health care, a health service fit for the East Riding Evaluation… Evaluation of first 3 months deployment (24 patients) showed: -Patient satisfaction generally very good -68% reduction in n/e admission costs -net saving per month -achievement of £0.5m QIPP saving feasible Evaluation by Hull University – full year evaluation due Dec 11

Telemonitoring in COPD – How can it work?

Telemonitoring in COPD – suggested mechanisms of action It has been suggested that telemonitoring can support COPD patients by; – Providing reassurance and support

Telemonitoring in COPD – suggested mechanisms of action It has been suggested that telemonitoring can support COPD patients by; – Increasing knowledge of disease process and enhancing self-care – Providing reassurance and support

Best health, best health care, a health service fit for the East Riding Roger 64 year old with chronic, severe COPD Housebound and anxious Frequently uses standby medication Frequent hospital admissions – anxiety rather than healthcare need Distrustful of clinicians due to previous experience After telehealth: Telephone contact to reassure Patient keeps diary of results and more knowledgeable about condition eg, trends/patterns More proactive about asking for help Reduced hospital admissions

Telemonitoring in COPD – suggested mechanisms of action It has been suggested that telemonitoring can support COPD patients by; – Enabling earlier detection of exacerbation (e.g. due to reporting of worsening symptoms) – Increasing knowledge of disease process and enhancing self- care – Providing reassurance and support

The impact of frequent COPD exacerbations - more frequent attacks increase mortality Soler-Cataluna JJ, et al. Thorax 2005;60:925–931 Group A: no exacerbations Group B: 1–2 exacerbations Group C: ≥3 exacerbations n=304 Time (months) p< p< A B C p= Survival probability
