Current status analysis of the prevalence and regional disparities of robot-assisted laparoscopic prostatectomy in Japan using diagnosis procedure combination data.
Observational study in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The introduction of the "da Vinci S HD Surgical System" marked a significant shift towards robotic surgeries in Japan. However, initial high costs and lack of efficacy data posed barriers to its widespread adoption. By 2023, more than 570 da Vinci units were operational in Japan, highlighting the growing acceptance of robotic surgery despite these challenges. This study aimed to investigate the prevalence and regional disparities in the adoption of robot-assisted laparoscopic prostatectomy (RALP) across Japan using diagnosis procedure combination data. This retrospective observational study analyzed data from 2857 urban and 4184 regional hospitals across 47 prefectures in Japan. The study focused on the number of RALP procedures, da Vinci systems, and certified urological surgery proctors. Multiple regression analysis was performed to identify significant factors influencing RALP adoption. Urban areas demonstrated a higher prevalence of RALP procedures and more da Vinci systems compared to regional areas, with urban hospitals performing an average of 937 RALP procedures compared to 195.5 in regional hospitals. The number of certified urological surgeons also showed significant urban-regional disparities, contributing to the overall imbalance. Our findings highlight substantial regional disparities in access to robot-assisted surgery in Japan, with urban areas benefiting from better access to advanced medical technologies and specialist training. Addressing these disparities will require targeted policies to improve the dissemination of robotic surgery systems and enhance training opportunities in regional cities.
