AbstractThe objectives of this study were to: (1) measure patient compliance with monitoring, (2) validate parental reports of alarms at home, (3) examine monitoring duration, and (4) compare documented monitor records with the traditional pneumogram to evaluate patients for monitor discontinuation. During the 1-year period from January through December, 1992, 114 infants were followed up with documented monitoring. Simultaneously, 113 infants were followed up with conventional monitors. Infants were premature, or victims of apparent life-threatening episodes (ALTE), or siblings of SIDS victims. Monitors recorded all episodes of apnea greater than 15 seconds and bradycardia less than 80 beats per minute. All families were contacted biweekly by telephone. Downloads were performed at regular intervals. Monitor downloads were compared with simultaneous pneumograms to assess the accuracy of a long-term, intermittent event-recording system versus short-term (6- to 12-hour) continuous recording. All families were highly compliant with the use of home monitoring. Although Caucasian families used the monitors more often than non-Caucasian families, all groups used the monitor > 75% of the time. True episodes were verified in 38% of patients by monitor downloads. Only 7.4% of all recorded events were true events. Of the real events, 51.2% were apneas of 16-20 seconds. No significant differences were found in overall duration of monitoring between documented and nondocumented monitors. In the premature infants, the duration of monitoring was significantly reduced in those infants found to have no true episodes over those with real events at home. Readmission for ALTE was reduced in infants with documented monitors. Premature infants without events were monitored an average of 24 fewer days (P = 0.03). Computerized monitor downloads were found to be equally, if not more, sensitive than pneumograms in evaluating infants for monitor discontinuation. Documented monitoring offers a viable alternative to traditional monitoring and pneumograms in assisting clinicians and families in evaluating their infant's progress. By accurately assessing compliance, distinguishing true from false alarms, and decreasing the need for pneumograms, these devices provide valuable information to clinicians and families.
