Issues and Challenges

Every aspect has its pros and cons. With the tumult of advantages, the use of AI brings ethical, social, and technical issues with it. Some of the major concerns that can hinder the widespread adoption of AI in healthcare include:

  • Data privacy and security – Data privacy and security is always a big challenge for internet-based services. Similarly in the case of AI-enabled healthcare services that collect, store, and analyze large amounts of data, need to be confident that their sensitive information is safe, secure, and well-protected.
  • High costs of creation and maintenance – Initially the cost of implementing AI services is quite high and apart from this it requires regular up-gradation and maintenance cost. 
  • Lack of standard rule and regulation – Different countries worldwide follow different Data Protection Laws. There is a lack of uniformity in data handling and storage. Similarly, the law pertaining to fraud detection, privacy, a criminal investigation, and trade negotiations policies vary widely. However, a uniformed regulatory framework and policy can significantly address these legal issues associated with AI in healthcare.

Way ahead

As of now the use of AI is limited for pre-defined problems or to carry out some specific routine tasks. now a days , Operational inefficiencies are one of the major issues for the healthcare industry. The AI has the potential to overcome challenges such as handling patient flow, hospital administration, designing treatment plans, and the optimal use of healthcare resources. Addressing all these critical issues can bring operational efficiency for healthcare organizations. Similarly, the AI has the capability to diagnose & predict the disease at a much higher rate than the professional. It saves a lot of time and effort put forward by healthcare professionals. Apart from these, AI has many other benefits and advantages such as a higher accuracy rate for clinical data interpretation, medical diagnosis, reducing the workload of nurses and medical support personnel, and many others.
