Out of hours intravenous fluid therapy: a prompt to guide prescribing

Recent NICE guidance has highlighted the importance of appropriate and safe intravenous fluid use. We aimed to improve the quality of out of hours fluid prescription in a Bristol hospital by ensuring that indications and cautions for fluid therapy were clearly documented at the time of initiation. Time-pressured on-call doctors need quick access to information regarding patients' care. A documented "fluid plan" allows doctors to undertake a more informed assessment of the patient's fluid balance, leading to safer prescriptions. Our ideal was for 100% of out of hours intravenous fluid prescriptions to be appropriate. Our process measures included the proportion of patients on intravenous fluids who had a documented fluid plan in the medical notes or on the prescription chart on Friday, prior to the weekend on call period. This was defined as mention of indications and/or cautions to fluid therapy. The introduction of a sticker to prompt fluid plan documentation did marginally improve use of fluid plans. It was notable that 96% of these were followed where plans were documented (n=23). Initiation of IV fluid with an accompanying plan is likely to make subsequent fluid prescriptions safer. Rapid turnover of staff and stationary proved significant barriers to consistent implementation of the sticker. Despite these challenges we demonstrated a "proof of concept", suggesting system modification to include fluid plans is safe and effective.
