Abstract
Purpose
Breathlessness is a common and distressing symptom in patients with advanced disease. Patients’ self-report is deemed to be the most valid method of symptom assessment. When patients are not capable of self-assessment, professionals’ assessment is often used as alternative but evidence on the validity is conflicting. The aim of this study was to compare self- and professionals’ assessment of breathlessness regarding presence and severity in patients with advanced disease.
Methods
Secondary analysis of a cross-sectional, multi-centre and nationwide register (HOspice and Palliative Care Evaluation (HOPE)). Documented inpatients from hospices and palliative care units from 2006 to 2008 who completed the self-assessed MInimal DOcumentation System (MIDOS) were included. Professionals’ assessment were based on the integrated symptom and problem checklist (symptom scores, 0–3). Cohen’s kappa (κ) was used to estimate the ‘level of agreement’ (LoA).
Results
Two thousand six hundred twenty-three patients (mean age, 66.9 (SD, 12.8); 54.4 % female; median Eastern Cooperative Oncology Group score, 3; 95.9 % with malignant disease) were analysed. Prevalence of breathlessness was 53.4 % (1,398 patients) by professionals’ and 53.1 % (1,410 patients) by self-assessment. Presence was correctly evaluated by professionals in 80.9 % of cases (sensitivity, 81.8 %; specificity, 79.8 %). Severity of breathlessness was correctly estimated in 65.7 % of cases. LoA was good (κ = 0.62) for the evaluation of presence of breathlessness and moderate (κ = 0.5) for the estimation of severity. The proportion of over- or underestimated scores was similar.
Conclusions
If patient’s self-rating, the gold standard of symptom assessment, is not possible, professionals’ assessment might be a valid alternative, at least for assessing the presence of breathlessness.
