Objectives To determine whether a novel urine collection device (the 'Pee-in-Pot (PiP)') produces the same rates of reportable urine culture results as standard of care (SOC) urine collection. To determine whether the PiP produces comparable microscopy results to SOC urine collection.
To estimate the carbon footprint of the PiP compared to SOC urine collection. Design A prospectively designed, single-centre, paired comparison study.
Setting A district general hospital in Southwest England, including antenatal clinical, accident and emergency, medical and surgical ward environments. Participants Adults aged 18 or over.
Interventions Urine passed through the PiP device before being decanted into a 10 mL boric acid tube for microscopy and culture, compared with the same urine contained only in a sterile plastic vessel before being decanted into a boric acid tube for microscopy and culture. Primary outcome measure The proportion of positive urine culture results.
Secondary outcome measures The proportion of heavy mixed growth culture results. Comparison of particle counts: all small particles, bacteria, red blood cells and white blood cells.
