Evaluation of the IBM Patient Physiological Monitoring System,

摘要

The IBM Patient Physiological Monitoring System (PPMS) is a respiratory oriented system which provides data on cardiac and respiratory functions as well as vital signs. A test was conducted to determine the degree to which the system fulfills its objective of improving the delivery and outcome of patient care, the acceptance of the system by operating personnel, and the economic feasibility of the system in the military setting. Findings were based on data concerning the treatment and outcome of care for 81 patients monitored using standard monitoring techniques, 82 patients monitored using PPMS, opinion survey results, and the system internal record of inquiries. Data concerning the treatment and outcome of care indicates that PPMS fulfills its objective of improving the delivery and outcome of patient care to some extent. In particular, there was improvement in the average length of stay in the ICU, the average time of ventilatory support required, and in the occurrence of pneumonia, arrhythmias, myocardial failure, oliguria, and anuria. It further indicates that the drug requirements of the two groups were different but reflected appropriate treatment of the existing medical problems.
