C hronic myeloid leukemia (CML) is a bone marrow and blood disorder accounting for 15% of adult leukemias. 1 CML is associated with a chromosomal abnormality where there is a translocation of chromosomes 9 and 22, which code for the BCR-ABL tyrosine kinase. The American Cancer Society estimates there will be 5,980 new cases of CML diagnosed (3,130 in men and 2,850 in women) during 2014 and 810 people will die of CML during this same time period.2 The median age at onset is 67 years, but CML occurs in all age groups.The 5-year survival rates for CML have increased dramatically with improved treatments, from 31% between 1990 and 1992 Chronic myeloid leukemia (CML) treatment is lifelong, and while it is important for patients to remain adherent to treatment, there are conflicting findings with respect to differences in adherence and persistence with dasatinib or nilotinib during second-line treatment.

Pregnancy and delivery are frequently compounded by complications that lead to increased costs and resource utilization.

We examined completion and compliance rates of rotavirus (RV) vaccination according to the recommendations of the Advisory Committee on Immunization Practices (ACIP) and the Food and Drug Administration approved Prescribing Information (PI) for Rotarix® (RV1, GlaxoSmithKline Vaccines) and RotaTeq® (RV5, Merck and Co.) among infants under one year of age covered by Medicaid programs. Healthcare claims data from state Medicaid programs that constituted the Truven Health MarketScan® Multi-State Medicaid Database were retrieved from May 2008-June 2012. Infants were grouped under PI and ACIP cohorts based on the dosing regimens followed. The overall compliance per PI (n=673,956) and ACIP (n=695,612) recommendations were 24.5% and 28.2%, respectively; completion rates were 30.3% and 32.6%, respectively. In the PI cohort, infants who received RV1 had significantly higher compliance as compared with infants who received RV5 (65.2% vs. 31.3%; p<0.0001); completion rates among infants receiving RV1 and RV5 were 65.3% and 46.4%, respectively (p<0.0001). In the ACIP cohort, compliance with RV1 was significantly higher than RV5 (68.8% vs. 45.9%; p<0.0001) as was the overall completion rate (73.5% vs. 48.8%; p<0.0001). While compliance is increasing year over year, overall compliance of RV vaccines is suboptimal, with over 40% of eligible infants unvaccinated in both populations. The 2-dose RV vaccine showed better completion rates and higher compliance than the 3-dose RV vaccine in the United States. Public health initiatives focusing on suboptimal compliance and completion rates of RV vaccination in the Medicaid population could improve these metrics, thereby offering protection against RV infection.
