Abstract 153: Does Telemetry Monitoring Improve Outcomes After In-Hospital Cardiac Arrest?
Introduction: Telemetry is increasingly used to monitor patients with lower intensities of care, but its effect on in-hospital cardiac arrest (IHCA) outcomes in non-critical care patients is unknown. We examined the relationship of IHCA with telemetry in non-critical care patients.
Methods: A retrospective cohort analysis of all patients in non-critical care beds that experienced a cardiac arrest at a large university-affiliated teaching hospital between calendar years 2011 and 2012 was performed. Data were collected as part of AHA Get With the Guidelines protocol. The primary endpoint was Survival to Discharge (SD); secondary endpoints included Return of Spontaneous Circulation (ROSC) and Time-to-Death (TD). The independent variable was whether patients were on telemetry. Analysis was performed using univariate and multivariate logistic regression for the SD and ROSC endpoints. Additionally, univariate and multivariate Cox proportional hazards regression was employed for TD analyses.
Results: Of 123 IHCA patients, the mean age was 75 ± 15 and 74 (61%) were male. 80 (65%) patients were on telemetry. Baseline demographics were similar except for age, patients on telemetry were older with a median age of 80.5 vs. 72.0 in the non-telemetry group (p=0.024). Of the 123 patients, 72 (60%) achieved ROSC and 46 (37%) achieved SD. By univariate analysis, there was no statistically significant difference between patients that had been on telemetry vs. no telemetry in terms of SD (OR=1.18, p=0.67), ROSC (OR=1.13, p=0.76) and TD (HR=1.21, p=0.56). Similar findings were obtained with multivariate analysis for SD (OR=0.92, p=0.87), ROSC (0.91, p=0.85) and TD (HR=1.05, p=0.85). A Kaplan-Meier curve of the TD endpoint is attached.
Conclusions: The use of cardiac telemetry in non-critical care beds is not associated with improved in-hospital cardiac arrests outcomes.
