National Registry of Diseases Office

About NRDO

Find out more about what we do, including our responsibilities, the current registries that we manage, and how we collect and enter data.

Last updated 13 August 2026

Background

We were set up by the Ministry of Health (opens in new tab) (MOH) in 2001 to collect data on selected major disease and health conditions in Singapore. This information is used to understand how these diseases and conditions are evolving in Singapore so that MOH can work on and improve the situation.

We currently manage four registries for common diseases, namely:

What we do

We are responsible for:

  • collecting the data and maintaining the registry on reportable health conditions and diseases that have been diagnosed and treated in Singapore

  • publishing reports on these health conditions and diseases

  • providing information to support national public health policies, healthcare services and programmes

How the registry works

The National Registry of Diseases Act (opens in new tab) allows us to access medical information and collect data on various health conditions in Singapore. Find out more about this legislation.

Data collection and entry

Data collection and entry are carried out by NRDO officers, known as registry coordinators, who are supervised by a trained nurse specialising in disease registry work.

We identify new cases using a number of sources, including:

  • notifications from healthcare professionals

  • hospital medical records

The registry coordinators verify and extract relevant information from hospital medical records and enter the data into the database.

Data management, data analysis and reporting

A team of data management staff will then manage the database to ensure that all data collected has been validated and properly anonymised. They also extract data to be used for analysis and reporting.

A team of analysts, including epidemiologists and biostatisticians, then analyse the data and produce reports regularly for the MOH. The reports contain aggregate data and trends on incidence, regularity and mortality of the disease covered by the particular registry.

The team will also produce aggregated data on an ad hoc basis for media queries and research projects.

Quality assurance

A team of quality assurance executives ensure that requests for data go through the proper levels of approval, and that data is being released according to the guidelines of the National Registry of Diseases Act (opens in new tab). 

The team also work with the registry staff to produce quality assurance policies and processes to ensure we are working at a consistently high standard.
