Cloud computing is an innovative paradigm meeting the user's demand for accessing a shared source comprising adjustable computational sources, such as servers and applied programs. The aim of the research is to conduct a bibliometric study of the scientific productions on "health cloud". The present study, was conducted using a bibliometric method in 2019 on PubMed database. It was selected 491 research papers over the period 2009-2019 for analysis. Data analysis was performed using VOSviewer and Excel software. The findings revealed that the production of health cloud-focused papers over a decade, excluding those in 2017, had an upward trend. The US, India, and China were the most productive in this respect. Having presented 5 papers on cloud computing, Costa, Lee, were most productive. The greatest co-occurrence was that of the words cloud computing, Internet, electronic health records, computer security, information storage and retrieval, algorithms, confidentiality, male, delivery of health care, computer communication networks, medical informatics, mobile applications, data mining, and Health information exchange. The results of the present study indicate the leading status of the US in health cloud publications. In view of the recognition received for using cloud computing, the trend of the papers in the base was upward in nature. On analysis of the co-occurrence of words, the largest cluster was that of cloud computing with 6 items focused on.
