Internal abuse on Public Health Care (S island)?

What have poor public health management example poor control of infectious diseases management (TB) and mismanagement of a public health system going to affect my country's economy and reputation?
There is undisclosed videotape on how poorly Tuberculosis is managed in my country and also AMD and other related issues in public healthcare. I am not sure whether to disclose or not?
There is this Senior Nursing Officer who is well known for her power-crazed mentality. She cut costs (like discouraging staff nurses wearing N-95 mask when treating patients who are on Direct Observation Therapy). Few of our staff have contacted latent TB but now in a manageable stage.
On the other hand, she order unnecessary stocks which eventually cost a burden to the clinic, kept a secret account book on this but tactfully hidden from the management.
Towards the management side, she have also the support from her nursing director, doctor-in-charge, human resource management, etc and etc.
Besides that, she liaises with the doctor in charge to cover up Advance Medical Directive Protocol. By right, all AMD should be sign as a legal document with a witness to what the doctor said to the patient. However in this clinic, the so-call witness is not present to listen to what the doctor said to the patient and blindly sign on the witness column. This is a strong legal issue. There is a tape on hand on how she discourages nurses to be present as a witness for AMD. This is for the ease of the doctors and by doing that she believes this would please the doctor in charge and other doctors.

Worst of all, she will harm people in her workplace capable of disclosing her misdeeds and a major workplace bully to the extent that all her subordinates have no choice but to give good comments about her unless they would to leave. She has coordinated with the management well (HR manager, Director of Nursing, Doctor-in-charge) but she has mentioned to her subordinates behind that these people are not in the sense of mind and inferior to her.

Even if I disclose the facts, she have the means to cover up and that is one of the thing she is very good at but with loopholes only if someone close with her is willing to help in the investigations.

She means more harm than good to the general public healthcare besides a workplace bully. But what can I do? I was thinking of letting the media know about what I have on hand but I think it is unfair for our Health Minister and the CEO of the public health organization on other hand.

If I disclosed, in my country, they will pretend to treat me as a friend initially, but later on for the reputation of the country to others, then they will put me down. I have tried that before already, and luckily still surviving.

I am still hanging and everyday is miserable. To me, Advanced Medical Directive is a very sacred thing as what I agree in line with my Health Minister. It should not be anyhow treated. The witness must be the witness as stated in the form, acknowledging what the doctor has advice the patient.

From a public health aspect, this is serious, as you well know, given the emergence of resistant strains. In fact, the CDC recently issued a MMWR discussing ultra resistant strains that don't respond to first line medications or 3 of the 6 second line medications. People need correct and timely treatment or the situation will only become worse.

Can you disclose in a way that will not revel your idenity?

What country you are in is going to help determine the best way to approach.
