COPD COPD affects millions of people worldwide, having major impact on daily life COPD is more than airway limitation (FEV 1 ) burden of COPD as experienced by the patient how to measure this burden and treat accordingly ("control panel" for physicians)? [Agusti, Thorax 2013; GOLD 2017]
Assessment of Burden of COPD (ABC) tool quantification and visualisation of the burden of COPD, thereby facilitating the integrated approach crucial for assessment and individualised treatment of COPD
ABC tool: development 1. definition of burden Burden of disease is the physical, emotional, psychological and/or social experiences of a patient with COPD. These experiences influence the patient's ability to cope with the consequences of COPD and its treatment. 2. face validity check (patients, healthcare providers) [Slok, Npj Primary Care Resp Med 2014]
ABC tool: development 3. condition a burden of COPD tool should meet 4. literature review > Clinical COPD Questionnaire (CCQ) comes close [Van der Molen, Health Qual Life Outcomes 2003] [Slok, Npj Primary Care Resp Med 2014]
ABC tool: development 5. development ABC scale = CCQ - symptoms - functional state - mental state + 3 items to measure emotions + 1 item to measure fatigue [Slok, Npj Primary Care Resp Med 2014]
ABC tool: development 6. development ABC tool = ABC scale + objective parameters - smoking - exacerbations - dyspnoea (MRC) - body mass index - lung function - physical activity > computer algorithm > visualisation (treatment advice) [Slok, Npj Primary Care Resp Med 2014]
ABC tool: rationale ABC tool = basis for shared decision making to support personalised care planning, including a personal treatment goal treatment goals often include lifestyle changes ABC tool = communication tool in primary and hospital care
Aim current study Assess effectiveness in pragmatic study: P I C O patients with COPD use of ABC tool care as usual disease-specific quality of life based St. George s Resp. Questionnaire (SGRQ) over 18 months
Netherlands Trial Register, NTR3788
Trial design pragmatic, two-armed, cluster randomised controlled trial 56 healthcare centres across the Netherlands 39 primary care 17 hospital care March 2013 to May 2015
Patient in/exclusion criteria spirometry-confirmed diagnosis 40 years of age or over understand and read the Dutch language exacerbation <6 weeks before study addiction to hard drugs life-threatening comorbid condition or pregnancy
Intervention vs. control Intervention: instruction healthcare providers to use ABC tool during routine consultations (min. every 6 months) Control: care as usual (Dutch COPD healthcare guidelines)
Outcomes Primary: clinically relevant improvement on the SGRQ = decrease of at least 4 points on the total score of the SGRQ between baseline and the 18- month follow-up Secondary: (amongst others) COPD Assessment Test (CAT) Patient Assessment of Chronic Illness Care (PACIC)

Secondary outcomes CAT not significant difference: 0.26 points (95%CI: 1.52 to 0.99) PACIC higher improvement in intervention group: 0.32 points (95%CI: 0.14 to 0.50)
Discussion ABC tool seems to have added value for patients with COPD patients treated with ABC tool were more likely to report clinically relevant improvement in their quality of life in the Netherlands: nationwide implementation in daily care ongoing
Discussion ABC tool for Germany? Opportunities: improved patient care? Threats: lack of time? lack of communication skills?
