Wisely measures include not ordering "continuous telemetry monitoring outside of the ICU [intensive care unit] without using a protocol that governs continuation." 1 Current guidelines for cardiac monitoring use recommend minimum durations for all adult class I and most class II indications. 2 However, telemetry ordering often fails to include timing or criteria for discontinuation. We determined the impact of a reduction in telemetry order duration within our hospital, hypothesizing this reduction would lead to earlier reassessment of telemetry need and therefore decrease overall utilization.
METHODS SettingDurham Veterans Affairs Medical Center (DVAMC) is a 151-bed tertiary care hospital within Veterans Affairs (VA) Integrated Services Network Region 6 (VISN 6) serving as the primary VA hospital for >54,000 patients and a referral hospital for VISN 6. Twenty-five telemetry units are available for use on 2 wards with 48 potential telemetry beds. All nonintensive care wards contain general medical and surgical patients, without a primary inpatient cardiology service. Most orders are written by housestaff supervised by attending physicians.
InterventionPrior to our intervention, the maximum allowable duration of telemetry orders was 72 hours. The duration was enforced by nursing staff automatically discontinuing telemetry not renewed within 72 hours. For our intervention, we reduced the duration of telemetry within our electronic ordering system in November 2013 so that orders had to be renewed within 48 hours or they were discontinued. No education regarding appropriate telemetry use was provided. This intervention was created as a qualityimprovement (QI) project affecting all telemetry use within DVAMC and was exempt from institutional review board review.
OutcomesOutcomes included the mean number of telemetry orders per week, mean duration of telemetry orders, mean duration of telemetry per episode, and the ratio of time on telemetry relative to the total length of stay. As a balancing measure, we examined rates of rapid response and "code blue" events. All measures were compared for 12 weeks before and 16 weeks after the intervention. Telemetry orders and durations were obtained using the Corporate Data Warehouse.
AnalysisAll outcome measurements were continuous variables and compared using the Student t test in Stata version 9.2 (StataCorp, College Station, TX).
RESULTSFollowing the intervention, overall order duration decreased by 33% from 66.6 6 8.3 hours to 44.5 6 2.3 hours per order (P < 0.01), mirroring the reduction in the maximum telemetry order duration from 72 to 48 hours (Table 1). However, an increase in telemetry order frequency after the intervention resulted in no significant change in telemetry duration per episode or the proportion of the hospitalization on telemetry (59.3 vs 56.3 hours per patient, P 5 0.43; and 66.4% vs 66.2% of hospitalization, P 5 0.58). Rapid response and code blue events did not differ significantly relative to the intervention (2.8 events per week before and 3.1 events...
