Efficacy
Statistical methods / analysis
Based on an estimated 25% enrollment rate, then n=184 screen-positive patients will provide sufficient power to measure this proportion with a 95% confidence interval width of 13%. From our preliminary data, we expect successful enrollment of 46 patients across 2 sites over 9 months. This will allow estimation of the proportion of patients who will complete at least 80% of doses of fluvoxamine with a 95% confidence interval width of 23%, assuming a completion rate of 80%.
The DRS-R-98 score, 3D-CAMS, TICS-M, Verbal fluency, WHODAS and GDS15 will be analyzed by Mann-Whitney or t- test depending on distribution.
The incidence of delirium (on 3D-CAM), will be analysed by Fisher’s exact test.
EEG analysis will be conducted by pwelch calculation of power bands and Mann-Whitney or t-test depending on distribution.
The biomarkers (IL-8 and NfL [and CRP, WCC and troponin]) will be log transformed and will be analyzed by Mann- Whitney or t-test depending on distribution.
Rates of data loss will be established using point estimates and sample variance will be estimated in intention to treat analyses. For all analyses, a P below 0.05 will be considered statistically significant.

Summary
Brief summary
Double-blind placebo-controlled randomised controlled feasibility trial to assess the feasibility of a larger multi-centre study. The rationale for the study are based on the known action of the drug fluvoxamine to reduce inflammation in the brain. The main objective of this pilot is to determine feasibility on a larger scale - including rate of recruitment, adherence to drug, ability to preform research activities and reporting adverse events related to the drug. As this is a pilot study our hypothesis is that more than 25% of patients approached will be happy to enrol in the study, 80% of enrolled participants will adhere to the study drug schedule and we will be able to collect measurable information on 90% of the participants. Secondary objectives include instance and severity of post-operative delirium, changes in EEG from intra-operative recording to and post-operative day 1, and collecting blood results/bio-markers associated with inflammation. Previous randomised control trials of prophylactic interventions to treat delirium have shown modest effectiveness.
The intervention (Fluvoxamine 100mg oral tablet) or placebo will be administered on the evening prior to surgery, day of surgery and post-operative day one. Participants will be asked to partake in cognitive assessments, delirium assessments and have routine bloods drawn as part of daily research activities.
