Congestive Heart Failure Weight Study

Time of Day and Accurate Weights for Patients With Congestive Heart Failure (CHF)

Early morning weights to monitor CHF patient's fluid status is common practice but there is a lack of evidence that this is the best practice. The purpose of this study is to determine if there is a difference in net weight gain or loss for hospitalized patients with CHF who are weighed in the evening instead of early morning.

Study Overview

• Status: Completed
• Conditions: Congestive Heart Failure
• Intervention / Treatment: Procedure: Weigh subjects on a scale in the standing position

Detailed Description

This is a quasi-experimental pilot study with prospective cohort design. Study subjects will be weighed in the early morning and then again in the evening for a minimum of three days. Analysis will be accomplished on data by analysis within-subjects data utilizing the paired t test. Other data to be collected includes dates of hospitalization, demographics, dose and timing of medications, lab results and documentation of comorbid conditions.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Body weight taken in a standing position; Subjects will be weighed in the early morning, as standard of care dictates. They will also be weighed after evening medications are given, around 9pm. The evening weight is not standard, therefore considered the study intervention.	Procedure: Weigh subjects on a scale in the standing position; Subjects will stand on a scale in the mornings, and the evenings for 3 days while hospitalized.
