ISO is the International Organization for Standardization that develops and publishes international standards. It is a network of national standards institutes from 163 countries. ISO has developed over 18,500 international standards covering many subjects. The development of ISO standards occurs through a six stage process involving technical committees and member body voting. Hospitals may pursue ISO 9001 certification for their quality management systems to improve processes, ensure quality care, and meet customer expectations. This can help hospitals provide affordable, timely care with clear communication and support services. NABH and NABL accreditation in India also assist hospitals in meeting quality standards.
