Objective: Estimate frequency and differences in omitted data between large sample of consecutive out-patient and in-patient population during 24-hour ambulatory blood pressure monitoring (ABPM). Design and Methods: Ambulatory blood pressure (BP) reports during the past 6-months were obtained using auscultatory devices (Accutracker II. SunTech Medical, USA). Monitors were pre-programmed to record BP every 30 min between 7 a. m. and 10 p. m. and every 45 min during night-time Data were analyzed as a mean&plusmn ; SD for continuous variables and as frequencies for variables on a nominal scale. For group comparisons ttest and chi-squared test were used, and values of p < 0.05 were significant. Results: We evaluated data from 260 consecutive patients referred to ABPM examination (26% in-patients ; mean age 57&plusmn ; 12 years ; 35% men). Mean 24-hour BP values were 133/77&plusmn ; 19/11mmHg (134/79x20/11 during day-time ; 124/70r20/11mmHg during nighttime) The number of used readings was 41:11 (33&plusmn ; 8 day-time ; 9&plusmn ; 7 night-time). A minimum of 70% used readings during ABPM examination was not obtained in 14% of all patients (12% out-patients vs. 16% in-patients ; p=0.410). 19% of all patients had no omitted readings at all (21% out-patients vs. 13% in-patients ; p=0.162). There where 6:11 omitted readings during daytime and 2i3 during night-time. The causes for omitted readings were background noise (48%), technical problems (27%) and body movement (6%). There was no statistically significant difference in the mean 24-hour, day-time or night-time values of systolic or diastolic BP, frequency and cause of omitted readings between our two groups of patients. Conclusions: In a large sample of our patients we found that in-patients had no better compliance and had similar frequency of omitted data in our ABPM database. The frequency of omitted data indicates that we need to pre-program our devices to record BP more frequently during the whole 24-hour period and in this way improve the efficacy of the ABPM.
