Infix scheduling across surgical specialties

NHS Lothian's Infix evaluation found 25% higher ophthalmology throughput per hour, with mixed results elsewhere

WorkingIndependent study

Problem

NHS Lothian needed to increase surgical capacity while addressing waiting-list backlogs. More efficient theatre schedules offered a way to use existing resources.

Approach

NHS Lothian contracted for Infix in 2022. An independent evaluation examined theatre efficiency across 4 specialties over 24 weeks. The scheduling software used machine learning.

Results

25%increase in ophthalmology patient throughput per hour after Infix implementation, measured in the independent evaluationIndependent study[1]

Takeaway

Results differed by specialty. Higher ENT utilisation did not increase patient throughput, and maxillofacial and plastic surgery showed no significant efficiency changes.
