BackgroundThis study aimed to assess the patient-rated level of discomfort during point-of-care ultrasonography (POCUS) of the heart, lungs and deep veins in a population of patients admitted to an ED with respiratory symptoms and to what extent the patients would accept being assessed by the use of POCUS if they had to be examined for possible disease.MethodsA questionnaire-based observational study was conducted in an ED. Inclusion criteria were one or more of the following: respiratory rate > 20/min, oxygen saturation < 95 %, oxygen therapy initiated, dyspnoea, cough or chest pain. Patients were examined by the use of POCUS of the heart, lungs and deep veins. Patient-rated level of discomfort and acceptance were assessed using a standardised questionnaire.ResultsThe median duration of the sonographic examinations was 12 min (IQR 11-13, range 9-23). The median patient-rated level of discomfort for all three types of POCUS was 1 (IQR 1-1, range 1-8) on a scale from 1 to 10. All but one patient (99.6 % (95 % CI: 98.9-100 %)), would accept being examined by the use of POCUS as a part of routine ED diagnostics.ConclusionsThe patient-rated level of discomfort during POCUS of the heart, lungs and deep veins is very low and the vast majority of patients would accept being assessed by the use of POCUS if the patients once again had to be examined for possible disease.
