The evolution of a National Quality Assurance Program in Sri Lankan Health Services dates back to 1989. With the publishing of the handbook on the National Quality Assurance Program in 1995 by the Ministry of Health, some institutions embraced the concept to introduce quality improvement program in their own institutions. The Quality Assurance Program was re-launched in 2000 with the concept 'Quality Healthcare through Productivity'.

The Castle Street Hospital for Women (Teaching) was identified as the focal point for the National Quality Assurance Program and then Castle Street Hospital was identified as the focal point for the National Quality Assurance Program of the Ministry of Health. Since then measures have been taken to expand this program to other hospitals island wide. As a result, hospitals such as Ampara DGH, Peradeniya TH and Kurunegala PGH have initiated their quality improvement program. It was believed that quality improvement program can be implemented only in the line ministry institutions because of the limited availability of resources in other hospitals. The Quality improvement program at Mahiyangana BH in 2004 - 2005 paved the pathway for hospitals which are governed by Provincial Councils and other smaller hospitals to improve quality in their hospitals. With this experience, a pilot study was carried out in five hospitals of different administrative levels in North Western Province. This gave an insight on the carrying out of the quality improvement program for the Ministry of Health. In 2007-2009, with this experience, the program was expanded to eight hospitals in the Southern and Uva Provinces. With these pilot studies it was identified that these ablishment of a District Quality Assurance Unit and Quality Management Unit are important to facilitate and monitor the quality improvement program. It was also recommended that an apex body be established to facilitate the quality improvement program through out the country. There fore, under the World Bank–HSDP funds,a building was constructed for the National Quality Assurance Program.

A consultative committee was appointed to decide on the scope and functions of the Directorate of Health care Quality and Safety. It was commissioned in August 2012.The Director at e functions under the principle of' A Centrally Driven, Locally Lead, Clinically Oriented, Patient Centered, Continuous Quality Improvement Program.

These included commencement of Monitoring and Evaluation mechanisms and Performance Review meetings for Line Ministry (42) Quarterly; and Provincial institutions- Base Hospitals Type B and above (101) biannually. The Directorate also created a platform for sharing experiences in 2013.

In 2013, twenty General Indicators and Performance Indicators (Checklist) and Surgical Safety Checklist (Circular and Guidelines) were introduced and in 2015, besides the development of the National Policy on Healthcare Quality and Safety, the Master Trainers Manual on Quality and Safety were also published in all three languages.
