This was a one-arm interrupted time series study, which used baseline trends as a counterfactual, to determine the effectiveness of TCI [49]. A cost-effectiveness evaluation was completed using activity-based costing to calculate the total incremental intervention cost divided by the number of improved records observed during the study period. The study had a 12-month baseline period, 5 months of TCI intervention scale-up, 9 months of active TCI implementation, and 4 months of post-intervention evaluation.
