Scope and Severity Index: A Metric for Quantifying Nursing Home Survey Deficiency Number, Scope, and Severity Adjusted for the State-Related Measurement Bias

SSI rendered a valuable metric to conduct quantitative analyses of nursing home deficiency number, scope, and severity across states. Future research should investigate the positive relationship between scope and severity of deficiencies and their number. Better understanding and correction of other factors introducing systematic bias to the survey results (e.g. regional impact) can further improve the accuracy of survey result evaluation.
