Electronic health record medical healthcare systems are developing widely. Things are being moved from the manual ways to automation and the patient records and health records are also being recorded electronically. One important aspect of any health record system is to ensure the confidentiality of the patient information because of its importance in the medical field.
In the recent times, the individual patient's and population's health information is recorded in form of electronically accessible files known as electronic health records (EHR). These are digital records which can be easily transferred across the internet.
A multitude of information is contained within the electronic health including billing information, patient's weight, age, vital signs, radiology images, laboratory test results, immunization status, allergies, medication, medical history and demographics etc.
Regardless of being in a paper form or electronic form, a medical health record is a tool of communication which helps in making clinical decisions, designing regulatory processes, accreditation, education, legal protection, research purposes, service coordination and evaluation of the efficacy and quality of healthcare provided.[1]
In order to ensure the safe and secure usage of the Electronic Health Records, the Australian government introduced the Personally Controlled Electronic Health Records Act in 2012. The act provides information regarding the rights of patients, obligatory information protection steps by the medical staff and organizations and the steps of registration with reference to the usage of patient's Personally Controlled Electronic Health Record.[2]
Since Electronic Health Records have more of a virtual existence than a physical one, protecting them also requires usage of appropriate technological tools and techniques. The following measures regarding the protection of Electronic Health Records are worth highlighting:
Ensuring the prevention of confidentiality breakage requires the provision of authorized access to the patient's healthcare information. In order to do so, the following steps could be taken:
Data theft and alteration has been a major problem in the recent times. Moreover, as far as patient health records are concerned, there are always potential threats of information leakages, data hacking, information destruction, manipulation or even blackmailing of patients by the external or internal users. Since the consequences of Information leaks are comparatively high in contrast to information alterations, one possible way to have information regarding the user of information is to audit information trails.[4]
Audit trails refer to keeping information about who had recently used or accessed patient records. Through the usage of audit trails and the above-mentioned security steps, Electronic Health Records could most probably be made the best way of collecting, storing, retaining and using patient health information.
