This study of Medicare inpatients in Syracuse, New York; demonstrated that most DRG 468 discharges were produced by a limited range of procedures and diagnoses. It also showed that patients were assigned to DRG 468 because of procedures wholly unrelated to the principal diagnoses, procedures that resulted from systemic difficulties, and procedures clinically unrelated to principal diagnoses which were assigned to different MDCs by DRG logic.
这项针对纽约州锡拉丘兹市医疗保险住院患者的研究表明，大多数DRG 468分类出院病例是由有限范围的手术和诊断产生的。该研究还表明，患者被归类到DRG 468是由于与主要诊断完全无关的手术、由系统性困难导致的手术，以及根据DRG逻辑被分配到不同MDC的与主要诊断临床无关的手术。
