Resource utilization in cancer patients with bisphosphonate‐associated osteonecrosis of the jaw. (19th February 2013) - Najm, MS
Abstract Background and objective Bisphosphonate‐associated osteonecrosis of the jaw (BONJ) is an emerging oral complication that occurs most commonly in the setting of high‐dose bisphosphonate therapy for cancer. The purpose of this study was to estimate the health care–related costs associated with a diagnosis of BONJ in patients with cancer evaluated and managed at one tertiary oral medicine practice. Methods This was a retrospective electronic medical record review of cancer patients with BONJ. All health care–related resources were abstracted using a structured chart abstraction tool; data captured included medications, imaging studies, laboratory investigations, procedures, and visits. Standardized references were used to assign costs in 2010 US dollars. Results Ninety‐two cancer patients with BONJ were identified who were followed for a median of 12 months. The median cost of a case of BONJ was $1667 (interquartile range from $976 to $3350). Medication costs comprised the majority (42%) of the total costs, followed by procedural interventions (22%), clinic visits (19.5%), and imaging studies (13.8%). Patient factors associated with higher median costs included a greater number of involved oral quadrants and more advanced BONJ stage. Conclusion There are considerable costs associated with the diagnosis and management of BONJ in patients with cancer, with medications accounting for nearly half of resource expenditures.
