Nihon Kohden is highly cognizant of the fact that medical devices directly involve human lives. To ensure that its products being used by customers and patients are safe and secure, Nihon Kohden makes daily efforts to improve the quality of its products. However, in the unlikely event a defect is found in one of our products after shipment that poses even a slight risk to the health of users, we have systems in place that enables us to carry out an immediate response and guarantee the safety and security of our customers and patients.

From Collecting Safety Information to Product Recalls/Modifications

Nihon Kohden compiles a host of information on safety, including defects discovered in the design and production process, safety information obtained from sources overseas, and customer complaints, among other sources. In this way, we are constantly monitoring for possible health risks posed to customers and patients.
Whenever new information on safety is obtained, the Chief Marketing Officer, Quality Assurance Officer and Safety Management Officer immediately convene a meeting to examine ways to address products that have already been shipped and to determine if a product recall or modification is necessary.
If a recall or modification is required, the health threat is categorized either as Class I, Class II or Class III following Japan’s Pharmaceuticals and Medical Devices Act, and Nihon Kohden as well as the Pharmaceuticals and Medical Devices Agency publish pertinent information on their websites. Immediately thereafter the Nihon Kohden Group’s sales and service staff contact customers directly.

Support System for Safety

Nihon Kohden not only strives to improve the quality and safety of its products, but also supports customers manage safety and helps spread medical technologies, which directly links with safety after a product has been delivered.

Support for Customers’ Safety Management

Nihon Kohden not only strives to improve the quality and safety of its products, but also supports customers’ safety management and helps spread medical technologies, to ensure safety after delivery of the product.
In Japan, Nihon Kohden deploys specialized safety managers nationwide who have received accreditation as Medical Device Information Communicators (MDIC)~{*}. We also organize safety workshops to ensure that customers use our products correctly. In FY2022, as in the previous fiscal year, it remained difficult to hold face-to-face workshops in the resurgence of the COVID-19. We held remote workshops and provided safety information needed in clinical practice using educational materials such as DVDs and slide presentations with voice-overs.
(FY2022 results: 716 workshops, educational materials provided to 261 facilities)


Main workshop topics

  • Safety workshops for use of patient monitors, defibrillators, and ventilators
  • Safety workshops for electrical safety and safety management of medical devices, and alarm report for patient monitors

*About the MDIC certification program
To improve the quality and safety and ensure correct usage of medical devices, the MDIC certification program is run by the Japan Society of Medical Instrumentation (JSMI) and accredits and develops personnel who can contribute to patient safety and the improvement of healthcare quality, by collecting and providing information on medical incidents and defects and sharing knowledge and technical information necessary for correct usage and maintenance of medical devices between medical safety managers, medical equipment safety managers, medical device users (physicians, nurses, and clinical engineers, etc.) and medical device marketing companies, including manufacturers, marketers and licensors, and repair outlets. To become a Medical Device Information Communicator, a person must take the MDIC seminar organized by the JSMI and pass the certification exam.

Providing the AED Linkage - AED Remote Monitoring System

AED Linkage - AED Remote Monitoring System

As more and more locations install AEDs, there have been situations where an AED was not readily available in good working order because the battery needed replacing or the electrode pads had passed their expiration date.

Committed to helping customers with daily maintenance to ensure their AED can be used at any time

Given this commitment, Nihon Kohden developed the AED Linkage AED remote monitoring system. This system helps support daily maintenance by notifying customers of issues with the AED, or the expiration date of the AED’s electrode pads and batteries, using an email generated based on information gathered from a self-test performed by the AED unit and sent to a server via a remote monitoring terminal. Nihon Kohden is dedicated to providing an environment where all of its customers can be able to readily use an AED with peace of mind.

Call Center Services

Nihon Kohden has set up a call center to respond to customer inquiries 24 hours a day 365 days a year whenever a problem occurs with a Nihon Kohden product or service. Telephone hotlines have been set up for each product line and operators in charge of each product undergo rigorous training to ensure that the call center can make the primary response to and help resolve customer problems.

Holding Seminars Nationwide in Japan

Nihon Kohden organizes a vital signs seminar and seminars co-sponsored with academic societies and for all physicians and other healthcare professionals as part of its efforts to ensure the latest, most advanced medical devices are used and understood correctly on frontlines of medicine.

In July 2004, Automated External Defibrillators (AED) were approved for uses by the general public in Japan and since then many public facilities have installed AED units onsite.
Nihon Kohden organizes classes on CPR and AED to ensure that more of the general public are able to use an AED if need be.
Number of AED lectures and participants in FY2021 in Japan:
Face to face: 291 lectures/3,490 people
Online: 119 lectures/1,137 people

Customer Satisfaction Survey

Nihon Kohden regularly conducts customer satisfaction surveys to continually improve the quality of its products and services. Feedback and opinions from these surveys are shared with development, production, sales and service departments.

Net Promoter Score (NPS) Surveys

One of the material issues in sustainability at Nihon Kohden is to pursue the highest level of quality in the world across the value chain. We set Net Promoter Score* as a KPI and started the survey in FY2021. In FY2022, we conducted the second survey. The overall NPS survey score in FY2022 improved by 1.3 points to -4.0 from -5.3 points in FY2021.
In terms of individual scores, the score for Contribution to Operational Efficiency improved by 0.1 points and the score for Cost-effectiveness of After-sales Service worsened by 0.2 points, indicating that improvement is needed. Through the NPS survey, we will make continuous improvements by analyzing areas that need improvement and taking measures to address then, including those areas that have been highly evaluated by our customers. As a partner to medical institutions and medical professionals, we will continue to work together with them to solve healthcare issues.

  • The NPS® survey is conducted to quantify the degree of attachment to and trust in a company or brand, which has traditionally been difficult to measure, in order to evaluate the customer’s experience at the point of contact with the company and apply it to improvements through future business activities. Since the NPS® survey has a high correlation with business growth rates, it is used by listed companies in the U.S. and Europe and is attracting attention in Japan as a new indicator alongside customer satisfaction.
    NPS® is calculated by the following method.
    Customers were asked to rate the service on a 10-point scale, with 9 to 10 being “promoters,” 7 to 8 being “passives,” and 0 to 6 being “detractors.” The percentage of promoters (%) to the total number of respondents was subtracted from the percentage of detractors (%), and the resulting number is the NPS value, which is expressed between -100 and +100.
