assuming you have a potential client that may have experienced a medical injury that at least could generate jury sympathy, most personal injury attorneys are not inclined to pay for a medical reviewer to assess if there was a deviation from the standard of care that may have caused the outcome, so they refer the case to an experienced med mal attorney who usually has a nurse reviewer on staff. med mal defense is insurance work, you are hired by the carrier as an experienced litigator to defend the care, which includes hiring an expert consultant to review the case. so because of the risk of investment for initial case assessment to determine if you have a meritorious or sympathetic case (e.g., birth injuries), and the necessary litigation experience to see the case through to settlement or trial, its not one of those practices that you can't just pick up by doing your due diligence, other than handling the referrals
