Intrathecal drug delivery systems for cancer pain control: Insights on current contemporary practices in the US.

6605 Background: About a third of cancer survivors report moderate to severe pain. Intrathecal drug delivery system (IDDS) is an implantable pain control option for treating intractable chronic pain not responsive to systemic opioid therapy. Studies on the current practices in the US around the utilization of IDDS for cancer pain are lacking. Methods: The Nationwide inpatient sample (NIS) dataset is funded by the Agency for healthcare research and quality (AHRQ) for multistate healthcare research & decision-making. Adult patients admitted to hospitals with a primary or secondary cancer diagnosis between 2016-19 were included. Patients undergoing IDDS implantation were identified using the validated International Classification of Diseases, 10th Revision, Procedure Coding System codes (00HU33Z Insertion of infusion device into spinal canal, percutaneous approach and 0JH80VZ Insertion of infusion pump into abdomen subcutaneous tissue and fascia, open). Baseline demographics, hospital characteristics, and type of cancer associated with IDDS implantation were evaluated in the study. Results: 22,895 patients underwent IDDS surgery amongst 7.06 million hospitalizations from 2016-19. The IDDS cohort consisted of patients in the 65-79 years age group (40.49%), female sex (50.42%), and Caucasian ethnicity (75.82%). Most IDDS surgeries were performed in large, urban teaching hospitals. Conclusions: Despite recommendations supporting IDDS use, a small minority received the treatment with significant racial & socioeconomic disparities in IDDS use. [Table: see text]
