Current practices in intraspinal therapy--a survey of clinical trends and decision making

Practice patterns were assessed via an internet-based survey distributed to physicians who manage implantable infusion pumps for pain management. Respondents consisted of 413 physicians who represented management of 13,342 patients, predominantly in the U.S. The survey used a standard questionnaire format plus two clinical vignettes to assess decision-making practices. The responding physicians chose morphine most often, but many other drugs were selected without clear indications. There was evidence of wide variations in clinical practice among physicians who use this modality. These findings highlight the need for practice guidelines based on research outcomes and expert experience to establish pathways for optimal management.
