There must be a difference in the cause of death. For example, from heart disease and infection. The former is unnecessary and the latter is necessary.

In addition, if it is a hospital medical accident, there is also a saying that the rescue is ineffective, and the doctor may just do his best. Medical conditions and poor equipment are external conditions. If hospitals in the same area have similar equipment, this is not a reason.

Moreover, there are not many conditions you give, and not all diseases are suitable for transfer to hospital for treatment. Some diseases that move or drag for a long time (such as dressing and fixation) will aggravate or lead to the death of patients, so these diseases are only suitable for local treatment.
