Brief summary

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.

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.

Interventions

PROCEDUREWeigh 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.

Recruitment details

Once all admission procedures were completed in the cardiac intermediate unit, the nursing staff asked CHF patients in their care, if they had interest in hearing more about the study. After a verbal yes, the PI or key personnel met with the patient to explain the study, review the consent form, and after ample time, obtain written consent.

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.
