Applying Evidence-based Practice

Do we really know how much we are feeding our patients?

BACKGROUND

Nutrition support is important in critical illness, and accurate recording is particularly important to determine whether nutritional goals are met both from a caloric and volume perspective.

OBJECTIVE

To assess accuracy of enteral feeding records, to increase nursing education and to improve nutritional documentation.

METHODS

An uncontrolled, prospective, pre- and post-intervention study was completed as part of a quality improvement initiative. This study was performed in a 950-bed university hospital (Philadelphia, Pennsylvania) and focused in a 25-bed, closed intensive care unit (ICU) with a multidisciplinary rounding team of intensivist, nurse, pharmacist, dietitian and respiratory therapist. Nurse researchers reviewed 188 patient electronic medical records (EMR) and compared the data to volume data saved on enteral feeding pump. Data analysis revealed inconsistencies between the pump readings and EMR. The need for a prospective intervention was recognized and implementation of this intervention included pump calibration and teaching modules aimed at improving enteral feeding protocols. During post-intervention, another 234 records were reviewed.

RESULTS

The intervention of an education program reduced the documented discrepancy between the pump readings and charted volumes from 44 to 33%. A correlation analysis also showed a tighter relationship post-intervention (rpost = 0.84 vs. rpre = 0.76, both had a p < 0.01).

CONCLUSION

This study highlights the importance of accurate nutritional monitoring in the ICU and demonstrates that educational interventions can improve enteral feeding protocols. Pump calibrations, frequent interrogation and vigilant nutritional documentation can improve enteral nutrition delivery. Future studies are needed to determine if the effects are sustainable and if further education will further improve documentation and delivery.

So You Want to Change Practice: Recognizing Practice Issues and Channeling Those Ideas

Applying the best evidence to support nursing practice and generating new knowledge for use in practice are the hallmarks of excellence and allow practitioners to meet patient care quality and safety priorities. Although identifying a patient care problem comes easily to staff nurses, the process of clarifying the problem and channeling those ideas through to a practice change can be daunting for bedside nurses. This article provides guidance to staff nurses who want to identify a clinical problem and change practice.

Development of an Evaluation Tool for a Clinical Practice Guideline on Nursing Assessment and Device Selection for Vascular Access

This study developed and tested a chart audit tool to assess the implementation of evidence-based recommendations for vascular access nursing assessment and device selection. Chart audits of 71 patients were conducted in a home healthcare agency and a community hospital prior to guideline implementation. Observations of initial infusion therapy and chart audit documentation of 31 patients were also compared. Results from observations indicated that nurses provided care consistent with the recommendations, but findings from chart audits indicated that assessment and decisionmaking were poorly documented. Studies that use only precomparison and postcomparison by chart audit may miss changes in nursing practice.
