Rationale – General
Problems associated with the capture of Problems associated with the capture of clinical, bedside measures are significantclinical, bedside measures are significant
Many are technique and skill dependentMany are technique and skill dependent Large data volume:Large data volume:
– 1 million bedside measures per year (96 beds)1 million bedside measures per year (96 beds)– 2700+ measures/day (96 beds)2700+ measures/day (96 beds)– ~30 measures/day/bed~30 measures/day/bed
Rationale – General
Examples:Examples:– Weights: Notoriously change in large Weights: Notoriously change in large
increments that do not correlate with the increments that do not correlate with the clinical pictureclinical picture

Rationale – Our ProjectRationale – Our Project
Pilot internal study showed 7% of Pilot internal study showed 7% of temperatures stored on medical surgical temperatures stored on medical surgical wards were inaccurately low (wards were inaccurately low (96.4°F)96.4°F)
Causes of inaccuracy:Causes of inaccuracy:– Poor technique/Poor probe placementPoor technique/Poor probe placement– Recent ingestion of hot or cold beveragesRecent ingestion of hot or cold beverages– Recent smoking or bathingRecent smoking or bathing– Poor patient cooperation (i.e. poor mental status etc.)Poor patient cooperation (i.e. poor mental status etc.)
PurposePurpose
To determine whether computerized, To determine whether computerized, bedside remindersbedside reminders (i.e. real-time bedside (i.e. real-time bedside feedback) can improve the accuracy of feedback) can improve the accuracy of bedside measures (bedside measures (temperature temperature measurementmeasurement))
To determine how the level of training (i.e. To determine how the level of training (i.e. RN, LPN, Aide, etc.) correlates with the RN, LPN, Aide, etc.) correlates with the accuracy of bedside measures accuracy of bedside measures ((temperature measurestemperature measures))

Methods – Intervention Methods – Intervention GroupGroup
A computerized reminder appears when A computerized reminder appears when the user attempts to store a temperature the user attempts to store a temperature 96.4 °F96.4 °F
The user can then either:The user can then either:1.1. Cancel temp and retakeCancel temp and retake
2.2. Cancel temp and do nothing Cancel temp and do nothing
3.3. Over-ride the reminder and store temperature but Over-ride the reminder and store temperature but then must provide a reason for doing sothen must provide a reason for doing so
