Medicine has become pretty standardized. Protocols for patient care have evolved. So healthcare organizations ought to follow the standards pf care.
If anybody has faced any negligence, they want to report to medical officer or any concerned person. As they will took strict action against it, other’s won’t pursue it more.

Good communication with patients, their family members and vive versa.
Strict actions to be taken in case of any negligence.

It’s crucial to view these incidents within the larger framework of systemic healthcare issues. Continuous training, standardized protocols, supervision, and clear communication between the healthcare team can significantly reduce such errors. Blame alone doesn’t solve the problem — accountability combined with structured improvement does.
