Purpose Buprenorphine is an opioid partial agonist used to treat opioid use disorder. While several policy changes have attempted to increase buprenorphine availability, access remains well below optimal levels. This study characterized how buprenorphine utilization in the United States has changed over time and whether there are regional disparities in distribution of the medication. Methods The amount of buprenorphine distributed from 2007 to 2017 was obtained from the Drug Enforcement Administration's Automated Reports and Consolidated Ordering System. Data were expressed as the percent change and milligrams per person in each state. The formulations and cost for prescriptions covered by Medicaid (2008 to 2018) were also examined. Results Buprenorphine distributed to pharmacies increased about 7‐fold (476.8 to 3179.9 kg) while the quantities distributed to hospitals grew 5‐fold (18.6 to 97.6 kg) nationally from 2007 to 2017. Buprenorphine distribution per person was almost 20‐fold higher in Vermont (40.4 mg/person) relative to South Dakota (2.1 mg/person). There was a strong association between the number of physicians authorized to prescribe buprenorphine and distribution per state (r[49] = +0.94, P < .0005). The buprenorphine/naloxone sublingual film (Suboxone) was the predominant formulation (92.6% of 0.31 million Medicaid prescriptions) in 2008 but accounted for less than three‐fifth (57.3% of 6.56 million prescriptions) in 2018. Conclusions Although buprenorphine availability has substantially increased over the last decade, distribution was very nonhomogeneous across the United States.
Objective Kaposi sarcoma (KS) of the larynx is a rare disease with few cases reported in the literature. This study aims to provide a comprehensive review of laryngeal KS, including patient characteristics, treatment, and clinical outcomes. Data Sources PubMed, CINAHL, SCOPUS, and Cochrane Library. Review Methods A systematic review of the published English literature was conducted. An electronic search and bibliographic examination of articles pertaining to laryngeal KS were performed. Demographic data, tumor site, treatment strategies, follow-up, and outcome were analyzed. Results A total 77 cases from 50 articles were included in the review. The mean age was 47.6 years (range, 8-81). There was an 8.6:1 male:female ratio. The most common presenting symptoms were dyspnea (n = 35) and hoarseness (n = 25). Laryngeal KS arose most frequently in the supraglottic region (n = 16). Chemotherapy alone (n = 27) was the most common treatment modality in patients with AIDS-associated KS, and surgical excision alone (n = 7) was most common in patients with other subtypes of KS (eg, classic, transplant associated). Average follow-up was 20.4 months (range, 0.75-120). Most patients with AIDS-associated KS died of other causes (n = 25), but most patients with other subtypes of KS were alive with no evidence of disease at follow-up (n = 13). Conclusion This review contains the largest pool of laryngeal KS cases to date. Long-term outcomes were generally unfavorable, often due to advanced HIV disease at the time of diagnosis.
Aims: Buprenorphine is an opioid partial-agonist used to treat Opioid Use Disorders (OUD). While several state and federal policy changes have attempted to increase buprenorphine availability, access remains well below optimal levels. This study characterized how buprenorphine utilization in the United States has changed over time and whether there are regional disparities in distribution. Measurements: Buprenorphine weights distributed from 2007 to 2017 were obtained from the Drug Enforcement Administration. Data was expressed as the percent change and as the mg per person in each state. Separately, the formulations for prescriptions covered by Medicaid (2008 to 2018) were examined. Findings: Buprenorphine distributed to pharmacies increased about seven-fold (476.8 to 3,179.9 kg) while the quantities distributed to hospitals grew five-fold (18.6 to 97.6 kg) nationally from 2007 to 2017. Buprenorphine distribution per person was almost 20-fold higher in Vermont (40.4 mg/person) relative to South Dakota (2.1 mg/person). There was a strong association between the number of waivered physicians per 100K population and distribution per state (r(49) = +0.76, p < .0005). The buprenorphine/naloxone sublingual film (Suboxone) was the predominant formulation (92.6% of 0.31 million Medicaid prescriptions) in 2008 but this accounted for less than three-fifths (57.3% of 6.56 million prescriptions) in 2018. Conclusions: Although buprenorphine availability has substantially increased over the last decade, distribution was very non-homogenous across the US.
