Intravenous fluid prescribing practices by foundation year one doctors – a questionnaire study

OBJECTIVES Foundation Year Ones (FY1s) are the most junior doctors in the UK who are often required to prescribe intravenous fluid to patients not under their regular care, during on-call or out-of-hours ward cover. This study aimed to investigate FY1s' practice and decision-making process of intravenous fluid prescribing to these patients. DESIGN Questionnaire survey. SETTING Survey on Practices during on-calls and out-of-hours ward covers. PARTICIPANTS FY1s of five National Health Service (NHS) hospitals in England and Scotland. RESULTS All 149 FY1s responded to survey. Eighty-six percent have been taught intravenous fluid prescribing during medical school, compared with only 48% in FY1 induction. More than half always/often checked the patient's urea and electrolytes (U&Es) (72%), read the fluid balance (58%) and observation charts (80%), discussed the case with nursing staff (75%), enquired about oral status (82%), identified the main diagnosis/operation (75%) and indication for intravenous fluid (72%) of the patient when prescribing intravenous fluid. However, less than half often/always read the medical notes (43%) or performed clinical examinations on patients (16%). Most FY1s (94%) always/often checked patient's U&Es when prescribing potassium. CONCLUSIONS The questionnaire study demonstrated variations among FY1s in the practice and decision-making process of intravenous fluid prescribing to patients unknown to them, during on-calls or out-of-hours ward covers. Such variations in practice should be addressed especially by medical and foundation schools, and NHS hospitals to improve patient care.
