A treatment plan effectiveness system (TPES) allows for the receipt of information related to a patient's functional deficits and from that information provides one or more treatment plans meeting predetermined criteria. TPES can provide an outcome focused analysis of available treatment plans available for a given diagnosis and functional deficit set, with statistical support, thus allowing a medical service provider to provide better, more consistent, substantiated care.Outcomes, after or during treatment plan administration, are added to TPES thereby enhancing the useful knowledge available to medical service providers serving future patients. A TPES according to the present disclosure can also provide automated evidence based documentation in support of a given treatment plan, for treatment plan decision making or for reimbursement.
