There are issues that the patient might face or think he or she will face by using computerized system rather than using papers mainly because they will think that it can be accessed by anyone. In any field: Nursing, Biomedical science or Physiotherapy that is same. According to a research by B. Rai, A. Srivastava (December 2014), here are some problems and how to overcome them.

User Authentication: When any user is trying to access the health record then only approved user will be able to access the record. Smart card based solutions can be used. Biometric based system is also in use for safeguarding the authorized access of records.

Confidentiality & Integrity: It is related to the accuracy and dependability of healthcare record and truthfulness and reliability of physical computer and network systems. Hacking cases on EHR systems may lead to changing patient data or damage of clinical systems. Also the data can be misused or the data can go out of the authorized people to the public that will hurt the patient’s private life.

Access Control: It is an important security issue in joint computing settings where medical records kept in databases and exchanged through heterogeneous Security and Privacy Issues in Healthcare Information System As roles and rights differ depending on the nature of the system and organization, it requires controlling of user’s right to use certain resources by allowing or refusing access to resources. It is easy for an unknown user to access the network if the far-off connection is not secure. Electronic systems should permit the central security features of role-based access, passwords, and audit streams. There is a serious privacy issues connected to genetic testing when it comes to biomedical sciences. Individuals are faced with a fear of service loss and life insurance. Hence the refusal to use effective genetic tests hurts persons, researchers, and doctors.

Data Ownership: It is also important when allocation of power to access of patient record is reflected. Who will own which data, delegation of authority over data? Also duties and accountabilities of data ownership should be handled clearly.

Data Protection Policies: As several units are involved in healthcare analysis system, overlapping organizational and functional limits, so suitable and reliable protection are necessary. Organizations require firm policies and procedures leading the use of physical media and transportable devices to prevent stealing or loss. EHR systems need continued development to manage security, add new and vital levels of security, block access to particular notes or lab results, track versioning, and cover sensitive admissions for release of information.

User Profiles: Several persons are involved in healthcare system like patient, doctors, healthcare organization, trusted third party, pharmacist etc. But the concerns related to describing user types and roles wanted to differentiate the functional requirements and security levels of users. There is great unpredictability and mismatch of patient documentation systems in healthcare facilities, making it difficult to exclusively identify patients within one facility or between other persons that have access. For an example the same person should be identified in the microbiology section as well as in the hematology section to diagnose the correct disease. A system of recognizing patients between departments must be for taking correct actions.

Misuse of Health Record: Some of the websites proposing EHRs, mostly the ones that offer storage space for free, are not worried with confidentiality. They may sell the data to other companies, or publicize on the same page as the content uploaded by the patient. In a multi-field setting, security of health records can be puzzling. Organizations must have the capability to isolate any records linked to treatment of ingredient misuse, as treatment of these patients can include multiple medical fields and document categories.
