    BACKGROUND: Robot-assisted radical cystectomy is becoming a common treatment for bladder carcinoma. However, in comparison with open radical cystectomy, its cost-effectiveness has not been confirmed. Although few published reviews have compared total costs between the two surgical procedures, no study has compared segmental costs and explained their impact on total costs. METHODS: A systematic review was conducted based on studies on the segmental costs of open, laparoscopic, and robot-assisted radical cystectomy using PubMed, Web of Science, and Cochrane Library databases to provide insight into cost-effective management methods for radical cystectomy. The segmental costs included operating, robot-related, complication, and length of stay costs. A sensitivity analysis was conducted to determine the impact of the annual number of cases on the per-case robot-related costs. RESULTS: We identified two studies that compared open and laparoscopic surgeries and nine that compared open and robotic surgeries. Open radical cystectomy costs were higher than those of robotic surgeries in two retrospective single-institution studies, while robot-assisted radical cystectomy costs were higher in 1 retrospective single-institution study, 1 randomized controlled trial, and 4 large database studies. Operating costs were higher for robotic surgery, and accounted for 63.1-70.5% of the total robotic surgery cost. Sensitivity analysis revealed that robot-related costs were not a large proportion of total surgery costs in institutions with a large number of cases but accounted for a large proportion of total costs in centers with a small number of cases. CONCLUSIONS: The results show that robot-assisted radical cystectomy is more expensive than open radical cystectomy. The most effective methods to decrease costs associated with robotic surgery include a decrease in operating time and an increase in the number of cases. Further research is required on the cost-effectiveness of surgeries, including quality measures such as quality of life and quality-adjusted life years.

    The 7th Global Conference on Health Promotion with the theme “Promoting health and development,closing the implementation gap” was held in Nairobi, Kenya, on 26-30 October, 2009. As an immediate outcome, “Nairobi Call to Action” was released at the end of the conference. The main theme of the conference aimed to clarify key strategies and commitments of each country in order to narrow its major implementation gaps in health and development through health promotion. Five urgent responsibilities were identified in the Call, which was based on the collective views of more than 600 international on-site delegates and online participants from more than a hundred countries. We would like to introduce the whole document and its Japanese translation to the Journal readers (It was translated by Koji Kanda, Hiroko Yamashina, Masamine Jimba, Keiko Otsuka, and Hidehiko Tamashiro).
