"Aku nak jadi doktor yg safe, takde kes negligence, suboptimal treatment..." Not easy. Not all can do, maybe none. In this era of defensive medicine...don't depend on yourself. Make sure there's a system to double check especially if you're on your own practice (baca:GP) and if you do locum, do get your institution's green light per protocol and get yourself indemnity cover. Human errs, and doctors are humans.
