RT Journal A1 Mitka M T1 IMproving medication adherence promises great payback, but poses tough challenge JF JAMA JO JAMA YR 2010 FD March 3 VO 303 IS 9 SP 825 OP 825 DO 10.1001/jama.2010.212 UL http://dx.doi.org/10.1001/jama.2010.212 AB Poor adherence accounts for an estimated 33% to 69% of medication-related hospital admissions, costing about $100 billion (Osterberg L and Blaschke L. N Engl J Med. 2005;353[5]:487-497). Harder to measure, but no less real, are the premature deaths and reduced quality of life for patients; increased patient and physician anger, frustration, and hopelessness; and skewed findings for clinical research.
