Key Challenges

Secured maintenance of Patient records digitally is one of the major concern in the healthcare industry. Patients tends forget to carry along their medical records and prescriptions while visiting a doctor. This causes a lot of hindrance in correct treatment. EHR solution is a response to this problem. But the security aspect of EHR solutions and the related trust factor from the patients was a challenge.

While planning and designing for this EHR system, the key challenges that were identified are :

  • Unavailability of patient medical records : Patients tends to forget to maintain and keep track of their hard copy medical records. In absence of the medical records and reports, Doctors encounter difficulty in further treatment and diagnosis. Absence of a EMR repository poses a problem for both doctors and patients during the medical treatment process. Hence, there is a need for a secured EMR software solution.
  • Mismanagement of Doctor appointment bookings : Management of appointment bookings in offline mode through phone calls or physical booking was cumbersome and error prone. Tracking the appointment status and availability for appointments was difficult. Availability of booking history for ready reference was a challenge in absence of a digital process for appointment bookings
  • Security & Privacy Concerns : Trust factor of patients on the EHR system was a major challenge. The EHR system would contain confidential medical and personal information of patients. These needs to be highly secured and access restricted. Ensuring Data security was a major challenge while developing this EHR system
  • Inefficient communication between Doctors & Patients : Patients always have follow up queries and clarifications for Doctors after a consultation. But it is a challenge to always consult the doctor in person. Also, unavailability of the doctors due to their busy schedules poses a challenge to communicate with them for follow up queries. Telemedicine solution would help in connecting with the doctors remotely easily and can solve the communication related issues to a great extent
