What’s in the license fee of a proprietary hospital information system?

What actually do we pay for when we purchase a proprietary hospital information system? Let’s dissect where the money goes. 1. software development. This goes to the salary of the programmers who were hired by the vendor to develop the software. Interestingly, if the software is already running in another hospital, this cost has been […]

Hospital Information Systems Cost Centers

Want to automate the hospital? First, it depends on how big is the hospital. HIS are expensive and unless the hospital is big enough to generate revenues, a full HIS is not advisable. Having said that, there is benefit for HIS — it’s just that you have to make sure you lay down the HIS […]

EHR Fundamentals

OpenMRS is short for open medical record system which is a result of research by Partners in Health (Boston) with South African counterparts. It runs on Java/Tomcat/Hibernate/MySQL, and has an elegant data model (EAV). For those interested in health […]
