kindly explain what is the difference between master of hospital administration and healthcare administration ?

Tata Institute of Social Sciences, Mumbai
IIHMR, Jaipur
IIHMR, Delhi, Bangalore and Kolkata.
ASCI, Hyderabad
NMIMS for pharmaceutical management.
The first year of training is the same for both the courses at institutes like IIHMR and depending on your choice and marks, you can choose a field in second year. Then onwards the curriculum and the internships differ.
Also, I would like to say that globally, healthcare administration is better accepted.
You will have to justify your decision of switching over from biochemistry to healthcare in interviews, also some experience in the field of healthcare improves your cv.
By and large, your colleagues will be from dentistry background but in the field of healthcare, they are considered almost equal to you as dental experience has nothing to do with the way healthcare industry operates. The only hurdle is MBBS colleagues which will always be considered superior to you, irrespective of your experience or position. You must consider all these factors before hand.
Healthcare administration will be a good option for you but avoid hospitals as they prefer MBBS background and thus hospital administration should not be on your cards.
