Acceptance and side effects of ambulatory blood pressure monitoring: Evaluation of a new technology

Ambulatory blood pressure (BP) monitoring is probably becoming a clinically useful procedure for the evaluation of hypertensive patients. Previous reports have shown that the devices are safe and serious side effects are rare. Discomfort and inconveniences associated with its use are more frequent. In this study, patient acceptance of ambulatory blood pressure monitoring (ABPM) was compared with acceptance of other diagnostic procedures and their side effects were assessed. Patients were asked to fill in a form and 129 of 166 patients responded, The acceptance was measured with a visual analogue scale which ranged from 'very annoying' on the left to 'not annoying at all' on the right. All forms were collected anonymously. Mean distance (cm) of the visual likert scale was 8.6 to 9.4 for the diagnostic procedures frequently used in routine patient care. Ambulatory BP measurement (ABPM) scored 6.1 cm, Reported side effects (in 27% of patients) were: pain (9%), skin irritation (8%), noisy device (8%), inconvenience with work (3%), haematoma (2%) and other (4%). Reports from the patients on sleep quality were: 23% normal, 61% minor disturbance, 14% bad sleep, and 2% did not sleep at all, It can be concluded that ambulatory BP monitoring was the diagnostic procedure with the lowest patient acceptance. Side effects of this new technology were reported by 27% of patients. However, risks are relatively minor, Sleep disturbances were very frequent and was a serious problem for 16% of patients.
