Nursing homes in the worst 10% group are those whose point estimates of the quality measures of decline in ADL functioning are among the 10%highest of the rates of all nursing homes (n=9,336). Nursing homes in the medium 80% group are those whose point estimates of the quality measures of decline in ADL functioning are between the 10% highest and 10% lowest of the rates of all nursing homes (n=9,336). Nursing homes in the best 10% group are those whose point estimates of the quality measures of decline in ADL functioning are among the 10%lowest of the rates of all nursing homes (n=9,336).
