The accuracy and precision of the Accutracker ambulatory blood pressure monitor

Prerequisite to the use of ambulatory blood pressure monitors in epidemiologic research is demonstration of a satisfactory level of accuracy and precision. Previous evaluations of these devices raise a number of methodological concerns which complicate interpretation of their findings. Also, important issues regarding the precision of blood pressure measurements and the identification of factors associated with measurement inaccuracies remain unaddressed. To assess the accuracy and precision of the Accutracker ambulatory blood pressure monitor, we obtained five serial estimates of resting blood pressure on 120 ambulatory subjects in The Johns Hopkins Medical Institutions in 1987. Two Accutrackers and two manual observers independently recorded blood pressure with the order determined at random. The fourth observer in each sequence obtained a replicate measurement. For both systolic and diastolic blood pressures, the mean difference between Accutracker and manual measurements was less than 3 mmHg for each pairwise comparison. Scatter plots and regression analyses demonstrated that both Accutrackers tended to underestimate high systolic and diastolic blood pressures. In bivariate and multivariate analyses, increased age was significantly associated with underestimation of systolic blood pressures by both Accutrackers. With respect to the precision of blood pressure measurement, no significant differences were present among the four observers. In summary, our data suggest that the Accutracker has satisfactory accuracy and precision, but that accuracy is not uniform across patient subgroups.

Evaluation of the DINAMAP blood pressure monitor in an ambulatory primary care setting

Automatic blood pressure recorders have gained acceptance in many clinical settings. New devices have usually been validated with invasive monitoring as the "gold standard." There is a lack of sound empirical evidence, however, supporting the routine use of these monitors in ambulatory settings. This study evaluated the DINAMAP 8100, an oscillometric automated blood pressure monitor, using the Hawksley Random-Zero Sphygmomanometer as the standard. A sample of 80 normotensive and hypertensive ambulatory patients from the Department of Family Medicine at the Medical University of South Carolina were studied. A clinical trial was conducted in which readings from the DINAMAP 8100 were compared with those from the Hawksley Random-Zero Sphygmomanometer, in a 2 (instrument) X 2 (arm) X 2 (investigators) X 4 (pairs of simultaneous measurements) factorial design. The DINAMAP 8100 overestimated systolic readings (mean difference = 7.6 +/- 9.1 mmHg, P less than .0001, paired t test). More than one third of systolic measurements and one quarter of diastolic measurements were greater than 10 mmHg discrepant from the standard. The results of this study suggest that routine use of the DINAMAP 8100 would lead to serious misclassification errors in screening for hypertension and in the follow-up of known hypertensive patients. The DINAMAP 8100, therefore, is not an appropriate instrument for routine use in primary care settings.     

Using performance indicators to monitor attendance at the Broken Hill blood lead screening clinic

Although the average blood lead level of 1-4-year-old children in Broken Hill has halved since 1991, about 1 in 5 still have blood lead levels higher than the national target (<10 μg/dL). The estimated proportion of children attending the Lead Clinic has declined, to approximately 42% in 2006, raising concern that some children with elevated blood lead levels may not be presenting, thus missing out on appropriate treatment and advice. The aim of this study was to describe patterns of attendance at the clinic as a first step to understanding what factors contribute to clinic attendance and non-attendance. Routinely collected data from the Lead Clinic database were used to describe the impact of factors such as child age, the lead-risk area in which they live, seasonal influences and specific promotional activities on clinic attendance rates from 1999 to June 2007. Estimates of the number of children living in each of the five lead-risk areas were derived from 2001 and 2006 census data and estimates of the number of children born to mothers resident in Broken Hill were derived from the Midwives Data Collection. Attendance rates declined by approximately one-third during the study period. Younger children, and those living closer to the central mining area, were more likely to attend for blood lead screening. Cohort analysis indicated cumulative attendance has declined, with children born in 2005 having a cumulative incidence at 18 months of age 5-10% lower than that for previous birth cohorts. The majority (54%) of children who developed a notifiable blood lead level (15 μg/dL) were first detected at 2 years of age or older, a number of whom (40%) had no recorded tests before the age of 2 years. The analysis has demonstrated the benefits of using an expanded set of performance indicators to monitor the blood lead screening programme. It provides valuable additional information about the reach of the programme. Next steps include seeking additional feedback from carers and the broader community, developing a strategy to increase screening and monitoring the effectiveness of efforts to reinvigorate the lead management programme.
