title: The value of telehealth in the early detection of chronic obstructive pulmonary disease exacerbations: A prospective observational study.
abstract: We aim to establish the value of telemonitoring in the early detection of chronic obstructive pulmonary disease exacerbations. We followed up patients undergoing chronic obstructive pulmonary disease telemonitoring for 4 months. We studied changes in the telemonitored data in the week prior to admission or to community chronic obstructive pulmonary disease exacerbation. A total of 183 patients were studied. In all, 30 chronic obstructive pulmonary disease-related hospital admissions and 68 chronic obstructive pulmonary disease community exacerbations were recorded. Changes in telehealth parameters occurred in 80 per cent (24/30) of admissions and 82 per cent (56/68) of community exacerbations. Although changes in telehealth data occurred in the majority of exacerbations, most individual symptoms was present in less than half the exacerbations and almost 20 per cent of exacerbations were not preceded by any change in telemonitoring data. Cough created significantly more alerts by those treated in the community (p = 0.008), whereas a drop in oxygen saturation created significantly more alerts pre-hospitalisation (p = 0.049). We conclude that further work is required to develop methods of identifying impending chronic obstructive pulmonary disease exacerbations with greater sensitivity and specificity.
