The study identified hospital utilization patterns by diagnosis-related group (DRG) produced by mastectomies for malignancy in Sacramento, California, and Syracuse, New York, for the years 1981-1984. A total of 3,449 discharges were included. Total and subtotal mastectomy discharges per capita increased in both areas. The proportion of mastectomy discharges attributed to total mastectomies increased in Sacramento and decreased in Syracuse. Mean stays for mastectomy DRGs declined by 13.72 to 56.38%. In 1984 mean stays ranged from 4.79 to 7.49 days for total mastectomies and 1.88 to 5.44 days for subtotal mastectomies. A major problem identified by the study was the lack of DRG sensitivity to differences in types of procedures. Under DRGs, radical and simple mastectomies are combined in one type of category, while subtotal mastectomies, quadrant resections, and breast biopsies are combined in another.
该研究确定了1981年至1984年期间加利福尼亚州萨克拉门托市和纽约州锡拉丘兹市因恶性肿瘤行乳房切除术所产生的按诊断相关分组（DRG）的医院利用模式。总共纳入了3449例出院病例。两个地区的全乳房切除术和次全乳房切除术的人均出院病例数均有所增加。萨克拉门托市归因于全乳房切除术的乳房切除术出院病例比例增加，而锡拉丘兹市则下降。乳房切除术DRG的平均住院天数下降了13.72%至56.38%。1984年，全乳房切除术的平均住院天数为4.79至7.49天，次全乳房切除术为1.88至5.44天。该研究发现的一个主要问题是DRG对手术类型差异缺乏敏感性。在DRG分类下，根治性乳房切除术和单纯乳房切除术被归为一类，而次全乳房切除术、象限切除术和乳房活检则被归为另一类。
