From: Impact of telemonitoring home care patients with heart failure or chronic lung disease from primary care on healthcare resource use (the TELBIL study randomised controlled trial)

Health status questionnaire VI     54.5%
  1. SD: Standard deviation.
  2. I Considering cause-specific admissions to hospital for respiratory and heart-related problems.
  3. II Obtained using the t-test for dependent samples, comparing the overall mean for each parameter and the mean in the 5 days before the admissions.
  4. III SBP and DBP stand for systolic and diastolic blood pressure, respectively.
  5. IV Considering only patients for whom weight data were recorded. Alerts were generated when ≥2 kg were gained over a period of 3 days.
  6. V Only 3 (5.6%) of alerts were for body temperatures over 37°C, the rest being for values below the lower limit.
  7. VI Negative responses to any of the health status questionnaires (on the personal digital assistant) generated alerts.
