Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed. For more information on this collaboration, see the comments published in The Lancet about the trial period, and our decision to make this a permanent offering, or visit The Lancet´s FAQ page, and for any feedback please contact preprints@lancet.com.

Background: Surgical capacity is reduced due to COVID-19; and actions are required to optimise access, as the waiting patients’ needs dramatically exceed the available resources. The Italian Liguria Regional Health Trust (ALiSa) commissioned a pathway for all cancer/urgent cases from the metropolitan area of Genoa (840,000 inhabitants).
Methods: The 6-week single-cohort feasibility-pilot of a software-aided, inter-hospital, collaborative multidisciplinary pathway covering all specialities in the Genoa Departments of Surgery. It modifies the Surgical Waiting List InfoSystem (SWALIS 2020) prioritisation model based on waiting time and clinical urgency by implicit criteria. We have introduced three new urgent subcategories: A1-15 days (certain rapid disease progression), A2-21 days (probable progression), and A3-30 days (potential progression).
Findings: 295 referrals were evaluated in 6 weeks without major criticalities from 12 Surgical Units. Waiting lists were weekly monitored, and theatres allocated based on the existing demand. Their urgency category frequencies differed between week 3 and week 4 (p = 0·031). The SWALIS priority score (% of the waited against maximum time) in the operated patients was 88•7 ± 45•2 at week 1 and then persistently over 100% (efficiency), spread over a controlled variation (equity), with a difference between the A3 (153•29 ± 103•52) vs. A1 (97•24 ± 107•93) (p <0•001), and A3 vs. A2 (88•05 ± 77•51) (p <0•001). 222 patients eventually underwent surgery. Neither pathway-related perioperative complications, nor delayed/failed discharges.
Interpretation: The pathway has allowed selecting the patients with the greatest need, optimising access even with rapid capacity modifications (+30% weekly). We will continue using the pathway in the COVID-19 “phase 2” and its scheduling policy to finely manage active, backlog, and hidden waiting lists. We are looking for collaboration for a multi-centre Service Improvement Research.
