Abstract
BACKGROUND: Given the complexity of the adjudication process and volume of applications to Social Security Administration's (SSA) disability programs, many individuals with serious medical conditions die while awaiting an application decision. Limitations of traditional survival methods called for a new empirical approach to identify conditions resulting in rapid mortality. OBJECTIVE: To identify health conditions associated with significantly higher mortality than a key reference group among applicants for SSA disability programs. RESEARCH DESIGN: We identified mortality patterns and generated a survival surface for a reference group using conditions already designated for expedited processing. We identified conditions associated with significantly higher mortality than the reference group and prioritized them by the expected likelihood of death during the adjudication process. SUBJECTS: Administrative records of 29 million Social Security disability applicants, who applied for benefits from 1996 to 2007, were analyzed. MEASURES: We computed survival spells from time of onset of disability to death, and from date of application to death. Survival data were organized by entry cohort. RESULTS: In our sample, we observed that approximately 42,000 applicants died before a decision was made on their disability claims. We identified 24 conditions with survival profiles comparable with the reference group. Applicants with these conditions were not likely to survive adjudication. CONCLUSIONS: Our approach facilitates ongoing revision of the conditions SSA designates for expedited awards and has applicability to other programs where survival profiles are a consideration.
