TY - JOUR AB - OBJECTIVES: To estimate the cost effectiveness of local anaesthetic (LA) transperineal prostate biopsy (TPB) compared to general anaesthetic (GA) TPB, considering both hospital/health system and societal perspectives. PATIENTS AND METHODS: Individual-patient data from a prospective pilot study of 80 patients who underwent LA (n?=?40) or GA (n?=?40) TPB according to patient preference was used. A cost-effectiveness analysis was conducted using a decision tree model considering cancer detection rates, perioperative and return to work considerations between LA and GA TPB. The economic model included costs associated with consumables, device (capital, maintenance) and personnel for each approach. Cost-effectiveness was evaluated in terms of the incremental cost/quality-adjusted life-years (QALYs) and incremental net monetary benefit. Probabilistic and one-way sensitivity analyses were performed. RESULTS: Clinical parameters were generally similar between groups, including overall (55%) and significant (35% vs 23%; P?=?0.32) cancer detection and procedure-specific duration (20 vs 21?min; P?=?0.53). Total procedure and recovery durations were longer in the GA group by 8?min (P?
