how do i start a suit against a hospital

It sounds like you have good reason to suspect that your mother received substandard medical care. Depending on her age and her underlying health problems, however, there may be a question about whether the case is financially viable. See the articles below which discuss this issue in more detail. At this stage of things your mother is still under active care and you do not know the outcome. As a result, you do not know the extent of damages, or whether possible mistakes were consequential.  Deal with the medical issues that you are facing, and then when the dust settles, if you want to investigate a malpractice case, contact an attorney. Statutes of limitations vary among states, so you have to be vigilant, but a lawyer cannot begin investigating a case while you mom is still admitted to the hospital. To investigate a malpractice case, you should contact a local medical malpractice attorney (one in your state).  They take these cases on a contingency basis which means you only have to pay if you succeed.  Additionally, initial consultations are usually free. You can use the "Find a Lawyer" service through this website to research medical malpractice attorneys.  Then, visit each attorney's website and look for a firm that has a record of successful verdicts,  ideally with experience in cases that involve your medical issue. If you are unable to find a lawyer who meets these qualifications within your state, sometimes you may contact an out of state lawyer who can refer you to a qualified attorney in your state while providing support related to the issues of medicine. Below are some articles you may find helpful.  They are written for a New Jersey audience (where I practice) but the ideas discussed in these articles usually apply in most other jurisdictions as well.

Since I am a lawyer, I need to advise you of the following when I communicate with you: Please note that by attempting to answer your question, I am not acting as your attorney. I will do nothing further to protect or preserve your interests in the absence of any additional discussion with you about this matter. John Ratkowitz, Esq.
