Using a person-centred model of Lean Six Sigma to support process improvement within a paediatric primary eye care...

Process improvement methodologies such as Lean Six Sigma are increasingly being deployed to address inefficiencies in healthcare. Simultaneously, global policy and strategy development stress the value of person-centredness in healthcare. This paper examines the application of a Person-Centred Lean Six Sigma Model (PCLSSM) to improve processes in a paediatric eye care clinic, specifically focusing on streamlining the referral system and optimising the clinic environment.

A quasi-experimental, single-site, pretest-posttest study was conducted over nine months using the Lean Six Sigma define, measure, analyse, improve and control (DMAIC) framework. Data were gathered through Voice of the Customer (VOC) sessions, Gemba observations, process mapping and referral letter audits. Key stakeholders, including clinicians, administrative staff and parents, co-designed the interventions to enhance efficiency and patient experience.

The application of the PCLSSM resulted in a 46% increase in right-first-time referral accuracy, a 20% reduction in referral processing time, a 13% increase in staff confidence in the referral system, a 158% improvement in staff satisfaction with workload and a 104% rise in child and parent satisfaction with their clinic experience. The implementation of an electronic referral system and an improved clinic environment contributed to these improvements.

This study is the first to integrate a person-centred approach with Lean Six Sigma in paediatric ophthalmology. The findings demonstrate the potential of combining process improvement methodologies with person-centred principles to enhance operational efficiency and stakeholder satisfaction. This approach can serve as a model for similar outpatient settings seeking to improve service delivery and patient experience.
