Risk-adjusted sequential probability ratio tests and longitudinal surveillance methods.
Regardless of the exact method employed, the application of statistical process controL SPRTs, or related longitudinal analysis methods can significantly improve the ability to monitor clinical processes and outcomes. Incorporation and adaptation of risk-adjustment and rare events into these methods represent important contributions to their use in health care. Fostering greater and more widesp...
متن کاملEvaluation of an automated safety surveillance system using risk adjusted sequential probability ratio testing
BACKGROUND Automated adverse outcome surveillance tools and methods have potential utility in quality improvement and medical product surveillance activities. Their use for assessing hospital performance on the basis of patient outcomes has received little attention. We compared risk-adjusted sequential probability ratio testing (RA-SPRT) implemented in an automated tool to Massachusetts public...
متن کاملMULTIHYPOTHESIS SEQUENTIAL PROBABILITY RATIO TESTS , PART I : ASYMPTOTIC OPTIMALITYVladimir
{ The problem of sequential testing of multiple hypotheses is considered, and two candidate sequential test procedures are studied. Both tests are multihypothesis versions of the binary sequential probability ratio test (SPRT), and are referred to as MSPRT's. The rst test is motivated by Bayesian optimality arguments, while the second one corresponds to a generalized likelihood ratio test. It i...
متن کاملSequential Probability Ratio Tests for Fuzzy Hypotheses Testing
In hypotheses testing, such as other statistical problems, we may confront imprecise concepts. One case is a situation in which hypotheses are imprecise. In this paper, we redefine some concepts about fuzzy hypotheses testing, and then we introduce the sequential probability ratio test for fuzzy hypotheses testing. Finally, we give some examples. Mathematics Subject Classification: 03E72, 62F03...
