It you feel there is a problem,
deliver the best care and prove it.

If a patient care problem occurs, for any reason, your best approach is to pursue the best care for it, and document that effort well. With regard to malpractice, two issues that affect the outcome most powerfully. First your concern for the patient, which will be perceived from your patient care and testimony if it should go to that. Secondly, any impression, real or argued by a plantiff's attorney, that there was an effort to cover up or alter records.
Your best course is to work to minimize or correct the clinical problem. And extablish that your efforts are within the standard of care, in the chart. Obtain consults to deliver the best care with documentation of the effort, and documentation that the standard of care for the problem is being applied.
Do not let anyone alter or remove notes. The problem will go from manageable to unforgivable with such actions.

Beyond the clinical care, consider that if it should lead to malpractice, your challenge with regard to a trial is establishing that you are within the standard of practice. The other issue will be what the consequences are for the patient, and only your effort to deliver the best care can help. But the standard of care argument will involve two experts arguing opposite sides. If you can establish in the chart additional expert opinion that the resolution of the problem was within the standard of care, and perhaps that the clincal problem occurred as an event within the standard of care, it will help. In doing so some additional opinions are on acting on your behalf at the time of the problem. This helps years later in a courtroom when memory will not be as effective as ink on paper, to follow the chinese proverb.
