About JANIS

Japan Nosocomial Infections Surveillance (JANIS) is a national surveillance program organized by the Ministry of Health, Labour and Welfare (MHLW) of Japan designed to provide basic information on the incidence and prevalence of nosocomial infections and antimicrobial-resistant bacteria in Japanese medical settings. JANIS was launched in 2000 with three divisions: the clinical laboratory (CL) division, antimicrobial-resistant bacterial infection (ARBI) division, and intensive care unit (ICU) division. Subsequently, two more divisions, the surgical site infection (SSI) and neonatal intensive care unit (NICU) divisions, were added in 2002. Further system renewal in 2007 allowed for dealing with all surveillance data online.

Although participation in JANIS is on a voluntary basis, there are currently more than 1,000 hospitals across Japan that are members of our surveillance system, enabling us to provide representative nation-level epidemiological data on nosocomial infections and antimicrobial-resistant bacteria.

The Five divisions of JANIS

JANIS consists of five divisions, and hospitals can choose which divisions to join, based on their need and capacity.

Organization and Management

JANIS member hospitals

JANIS targets hospitals with more than 200 beds, which accounts for approximately 30% of all hospitals in Japan. There are approximately 2,100 hospitals with more than 200 beds; almost half of them participate in at least one JANIS division. JANIS is a voluntary program, and there are neither legal obligations nor financial support for participation. Calls for participation are made on an annual basis and the list of JANIS member hospitals is available on the JANIS website.

Management of the JANIS system

JANIS is a project of the Guidance of Medical Service division in the Ministry of Health, Labour and Welfare of Japan. The JANIS management office is located in the Department of Bacteriology II in the National Institute of Infectious Diseases. The JANIS management office works on practical issues related to surveillance with the data management contractor.

The JANIS management committee consists of eight experts in associated fields such as hospital epidemiology, clinical infectious disease, surgical site infection, clinical laboratory medicine, and antimicrobial resistance. The committee reviews data collected by JANIS (e.g. annual report) and makes recommendations for improving the surveillance system.

Surveillance data and feedback information

JANIS member hospitals are required to submit surveillance data monthly, or once to twice a year, depending on division participation. Hospitals that do not submit surveillance data for a certain period of time are asked to withdraw from the surveillance program. The JANIS system provides two types of information, Open Report and Feedback Report.

JANIS Open Report

The goal of the JANIS Open Report is to provide national data on the incidence of nosocomial infections and the prevalence of drug-resistant bacteria in Japan. The Open Report is publicly available on the JANIS website.

JANIS Feedback Report

The Feedback Report is provided only to JANIS member hospitals that have submitted surveillance data. Each JANIS member hospital can access only its own Feedback Report, which consist of summaries on the incidence and prevalence of nosocomial infections or drug-resistance in each respective institution. JANIS member hospitals are expected to evaluate their infection control strategies using this Feedback Report. To facilitate this evaluation, the Feedback Report has figures on each institution's data plotted within box-plot graphs of all JANIS member hospital data.
