Thank you for using our forum. My name is***** am another expert on the forum, your prior expert had to "opt out" (this sometimes happens).
I have reviewed the information you posted above, and I do believe I can provide you the information you need to start looking for appropriate local attorneys to represent you in getting compensation for your husband's subsequent injuries and illnesses that are compounding his initial injury in the home.
I can also provide you with a general idea of what a medical malpractice case deals with (so what your attorney is going to be looking for).
Medical malpractice claims are based on expert testimony, this means you, or your attorney, will need to find a medical expert in the same, or similar field, to testify as to the standard of care in the industry, whether your physician or facility's conduct fell below that standard, and whether that negligence was the cause of your injury. The same (or a different) expert can then testify as to your projected future damages and cost of medical care.
Due to the complexity of these claims, I highly recommend that you retain a medical malpractice plaintiff's lawyer (also called trial attorneys). Fortunately the majority of these attorneys will provide you with a free consultation, and many will represent you on a contingency basis (they will advance the costs of litigation and legal services in exchange for a portion of your successful settlement or judgment).
You can find local attorneys using the State and Local Bar Association directories, or private directories such as www.AVVO.com; www.FindLaw.com; or www.Martindale.com (I personally find www.AVVO.com to be the most user friendly).
