Reducing the number of invalid surgical consents in the day surgery unit

Abstract

Aim To reduce the number of invalid surgical consents in the Singapore National Eye Centre Day Surgery Unit over a period of 6 months. Methodology A multidisciplinary team involving doctors, nurses, day surgery unit, operating theatre, listing and clinical audit staff looked into the listing process and the root causes of the high number of invalid consents. A Pareto chart detailing the top causes of invalid consents was drawn, and with a prioritisation matrix, feasible yet effective changes were identified and effected. Plan-Do-Study-Act (PDSA) cycles included moving consent checks upstream, getting invalid consents amended on the same day, sending emails to raise awareness on invalid consents and posters in clinics to emphasise the correct way to fill up consent forms. Result There has been a progressive downtrend in the monthly mean percentage of invalid consents since the introduction of PDSA cycles. There was a significant reduction in the mean rate of rejected consents from the preintervention phase of 15.2% to the postintervention phase of 11.3%, shown with a Z score of 6.56 (P<0.05). Sustainability was also demonstrated with multiple consecutive points below the median of 14.5% on the postimplementation phase of the run chart, with estimated time-efficiency savings of USD$19 738.50 annually. Conclusion Errors in the workplace can be reduced with a concerted effort from multiple stakeholders. It is important to have a thorough look at processes with concerned parties, so that different perspectives and skill sets can be harnessed to determine and implement feasible and effective interventions.
