ABSTRACT The websites present essential healthcare information to patients, from disease symptoms, admission, and discharge to post-care. The present study proposed the CRRAV Model (Credibility, Reliability, Readability, Acceptability, and Validity) for website quality contents of Hospitals, developed from the Expectation Disconfirmation Model, Web QIM, Web Qual Serruni Lucci Model, and Minerva Model. The study also aims to assess the internet information on heart disease and compare and evaluate the quality of HCOs in developed countries like the USA and developing countries like India. The DISCERN instrument, HONcode, and WRAPIN can improve the patient’s standard of information and satisfaction and remove the growing skepticism about the website on quality issues. The websites containing heart disease information with HONcode certification and WRAPIN were only four out of 65 in the USA. Out of all the evaluated websites, only a small number meet the criteria of DISCERN instrument and are accredited by HONcode. Besides this, government agencies have no regulation, supervision, or control in USA and India. There are no single quality criteria and international agreement for quality assessment of healthcare websites, except HONcode and WRAPIN.
