title: Serious health events and discontinuation of routine cancer screening.
abstract: Recently revised US Preventive Services Task Force screening guidelines for colorectal, breast, and prostate cancer contain separate recommendations for persons younger than 75 years and those 75 years or older. Developing an understanding of whether and how patients discontinue screening is important for evaluating the potential benefits and drawbacks of age-delimited screening recommendations as a tool for reducing overdiagnosis rates. Using Surveillance, Epidemiology, and End
  
  
  
  -Medicare data from 1998 to 2007, the authors identified a sample of 32,189 female and 27,669 male fee-for-service Medicare beneficiaries who received 2 consecutive breast or prostate screens, 1 year apart. They then estimated the impact of serious health events, such as heart attacks and strokes, on continuation of screening. Rescreening rates among beneficiaries who did not experience a serious health event were 78% for women and 82% for men. Rescreening rates among beneficiaries who experienced a serious health event were 55% for women and 57% for men. The rate ratios associated with a time-varying indicator for the 2-year period following a serious health event were 0.79 (95% confidence interval: 0.76 to 0.81); P < 0.001) for women and 0.87 (95% confidence interval: 0.85 to 0.89; P < 0.001) for men. Approximately one-third of patients and physicians discontinue or temporarily suspend screening for breast and prostate cancer following serious health events. Findings suggest that not all patients persist with screening until they die.
