OBJECTIVES To evaluate the incidence and causes of infusion alarms in a NICU/PICU setting. METHODS We conducted a 90-day prospective analysis of event logs downloaded daily from infusion pumps (syringe and volumetric pumps). The details about conditions surrounding alarm events were described daily by bedside nurses on a standardized form. The occlusion pressure alarm was set at 300 mm Hg on each device. RESULTS Forty-one pediatric patients including 12 neonates, mean weight 11.0 ± 11.3 kg (minimum–maximum, 0.48–50), were included for a total infusion time of 2164 hours. Eight hundred forty-three infusion alarms were documented (220 [26.1%] occlusion; 273 [32.4%] infusion completed; 324 [38.4%] door open/syringe disengagement; 26 [3.1%] air-in-line) resulting in an incidence of 4.7 infusion (1.2 occlusion) alarms per patient per day. Detailed conditions surrounding occlusion alarm events were documented in only 22.7% (50/220) of the cases. Of these, 36% (18/50) were related to closed or clamped lines, 4% (2/50) to syringe change, 16% (8/50) to drug injection, and 8% (4/50) to patient-related factors. The remaining 36% (18/50) occurred without any apparent external cause during ongoing infusion, among these drug incompatibilities were a potential cause for 12 events. CONCLUSION Alarms from infusion pumps were frequent in the NICU/PICU setting, a quarter of them resulting from line occlusion. Other than well-known triggers (mechanical and patient factors), drug incompatibilities were identified as a potential cause for occlusion alarms in this pilot study.
