Relationship with Customers

Quality and Safety of Products and Services

To achieve this quality policy, Nihon Kohden sets Group-wide targets and continually strives to ensure quality and enhance customer satisfaction in all processes, from development to production, sales and after-sales services. Our goal is to be a Company that is continually viewed and supported by customers as a trusted partner.

In FY2021, Nihon Kohden conducted six product recalls, causing inconvenience to those in clinical practice. We are making company-wide efforts to prevent any reoccurrence and are pursuing the world’s highest quality levels throughout the entire value chain.

Quality Targets

In FY2022, we will take actions to achieve the following quality targets.

1) Build a global quality management system to strengthen regulatory compliance and post-marketing monitoring in each country.
Healthcare systems in every country are being overwhelmed as a result of the COVID-19 pandemic, and demand for high-quality medical devices is rising worldwide. Nihon Kohden is gathering information on medical device related laws and regulations in each country and comprehensively disseminating it within the Company, reducing global product registration times, and achieving timely launch of products to global markets. We are also improving post-marketing monitoring systems and using the acquired information to enhance internal processes and provide feedback that is useful for products, leading to higher product quality.

2) Establish a product supply and service system that results in greater customer satisfaction, and achieve high rates of utilization by customers.
To have the customers feel continuous satisfaction with their purchase of Nihon Kohden products, we are continuing our efforts to design and manufacture products with low failure rates. To achieve this goal, we set quantitative targets for utilization rates, periodically review them, and provide feedback for use in design, production and service activities. In addition, we employ new technologies for remotely monitoring the status of product utilization rates, which lead to the prevention of failures. We are also working to reduce the time from receipt of products for repair to the provision of loaner devices as well as reducing repair times.

Integrated Quality Management System

Medical devices supporting the frontlines of medicine require extremely advanced degrees of quality and safety.

Japan as well as countries in Europe and North America each has rigorous standards and legislation regulating entry into the medical devices market. For example, the United States has QSR (conventionally GMP) established by the Food & Drug Administration (FDA) for the design and manufacturing processes of medical devices. In Europe there is the Medical Devices Directive (93/42/EEC), while Canada has medical device regulations and quality standards developed by the Canadian Standards Association (CSA).

Nihon Kohden not only complies with these regulations, it was among the first in the industry to ensure that its systems and practices conform to global standards to develop and manufacture medical engineering devices that have high degrees of quality and safety. To demonstrate its compliance with these standards, Nihon Kohden has received a number of certifications and accreditations by third-party institutions.

Nihon Kohden has also received Medical Device Single Audit Program (MDSAP)* certification ahead of other manufacturers in Japan.

To supply products globally in a timely manner, Nihon Kohden has worked to establish a quality management system and strengthen the system for applying for approvals in each country.
Nihon Kohden has established a system that monitors quality over the entire life cycle of medical equipment, including at the design, development, manufacturing, sales, maintenance, and disposal stages. The monitoring results for each stage are collected by the Quality System Manager and reported to the President three times a year. Through the implementation of this system, the Company aims to reduce the quality risk for each product to zero and maintain it there.

* MDSAP is a third party Auditing Organization's program to conduct a single regulatory audit of a medical device manufacturer that satisfies the relevant requirements.

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 the 2021 NPS survey, the overall score was -5.3 points. Individual scores averaged 7.6 points for Corporate Image and Contribution and 7.7 points for Satisfaction with Sales and Service.
Through this NPS survey, we hope to understand and analyze what our customer value and what we need to improve in order to further enhance our quality and continue to be a partner with medical institutions and medical professionals, working together to solve the issues facing healthcare.
* 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.

Ensuring Product Safety Post Release

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 FY2021, 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.
(FY2021 results: 610 workshops, educational materials provided to 290 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
*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: 120 lectures/1,229 people
Online: 105 lectures/1,097 people

Ensuring Fair Business Practices

Nihon Kohden recognizes that carrying out sound, fair, transparent, open, positive and competitive business activities in accordance with the Nihon Kohden Charter of Conduct will foster greater trust from society and is absolutely essential for the continuity of its business.
We constantly strive to educate stakeholders about this policy to ensure that it is made known to and practiced by all across the value chain, including not only executives and employees, but also customers and business partners.

Heightening Transparency of Relationships with Medical Institutions

In recent years, a number of scandals involving inappropriate relationships between pharmaceuticals and medical device manufactures and healthcare professional have come to light in countries around the world. As a result, society now demands that such vested interests be made known widely to secure the safety and best interests of persons receiving medical care. In the U.S., the Sunshine Act, part of the country’s healthcare reform, took effect in August 2013, while in Japan similar guidelines on transparency, although voluntary in nature, have been applied to pharmaceuticals companies starting in 2012 and medical devices manufacturers in 2013.

Nihon Kohden carefully follows these laws and guidelines and discloses its relationships with healthcare professionals using appropriate means. By doing so, we are seeking to foster greater trust in the Nihon Kohden Group and the healthcare industry.

In-house Training on Sound and Fair Business Practices

Nihon Kohden regularly conducts compliance training for all of its employees in Japan to ensure they continually maintain the correct understanding and mindset toward sound and fair business practices. Departments related to sales and procurement have established legal affairs training tailored to the needs of their organization, which includes Fair Competition Code and the Act against Delay in Payment of Subcontract Proceeds, Etc. to Subcontractors, to foster greater understanding toward fair business practices.
Furthermore, Fair Competition Code Instructors are deployed to each of our sales subsidiaries and departments to support employees with engaging in sound and fair business practices, which ensures Nihon Kohden has system in place to empower its employees to take the right actions.
