Inappropriate prescribing of intravenous fluid in adult inpatients-a literature review of current practice and research.

ABSTRACT

WHAT IS KNOWN AND OBJECTIVE: It is known that mismanagement of intravenous (IV) fluid therapy may cause serious complications. The 2013 NICE guideline on intravenous fluid therapy in hospitalized adults also emphasizes the importance of appropriate prescribing of IV fluid. So far, no systematic review of the incidence and types of inappropriate prescribing of IV fluid has been conducted. Therefore, this study was undertaken to review the research literature on inappropriate prescribing of IV fluid in adult patients and develop corresponding strategies for improving practice. METHODS: A comprehensive literature search was performed. Critical appraisals were conducted on the articles drawn from the search, and an analysis was performed on the results. RESULTS AND DISCUSSION: Incorrect volumes and types of IV fluids prescribed, classified as misprescribing, was the most common type of inappropriate prescribing. Commonly, patients on IV fluid therapy were prescribed a greater volume of fluid and amount of sodium in excess of normal requirements. Doctors did not always check the body weight, serum electrolyte level and serum creatinine before prescribing IV fluid for patients. The other common type of inappropriate prescribing was incomplete/incorrect prescription writing. These common inappropriate prescribing of IV fluid could be caused by insufficient knowledge and training of the prescribers. In addition, the ignorance of the importance of IV fluid prescribing also contributed to this behaviour. WHAT IS NEW AND CONCLUSION: There is an urgent need to make doctors aware of these problems and enhance appropriate training on IV fluid prescribing, especially on the appropriate volume and amount of electrolytes. Pharmacists could exert a role in reviewing the fluid prescription chart for improving clinical practice.
