The aim of this study was to examine the effect of patient turnover and acuity on worked hours per patient day (WHPPD).
An examination of staffing plans publically posted by Massachusetts hospitals with more than 300 beds revealed that less than 40% were within 5% of their planned versus actual WHPPD.
Three years of WHPPD data collected from 14 adult acute care units were correlated with patient turnover and acuity data. A weight factor was retrospectively added to 8 paired units' planned WHPPD where correlations were identified.
Twelve units (86%) showed significant correlations between WHPPD and patient turnover. Correlations between patient acuity and WHPPD were significant only at the aggregate level. After weighting WHPPD, the 8 paired units demonstrated a decreased variance between planned and actual WHPPD.
Using a weight factor added to WHPPD to right size acute care medical-surgical units may be useful for accurate staff planning and budgeting.
本研究旨在探讨患者周转率和病情严重程度对每位患者每日工作时间（WHPPD）的影响。
对马萨诸塞州 300 张以上床位的医院公开公布的人员配备计划进行了检查，结果发现，不到 40%的计划与实际 WHPPD 相差在 5%以内。
从 14 个成人急性护理病房收集了三年的 WHPPD 数据，并与患者周转率和病情严重程度数据相关联。在确定相关性的 8 对单元中，回顾性地为计划 WHPPD 添加了权重因素。
12 个单元（86%）显示 WHPPD 与患者周转率之间存在显著相关性。患者病情严重程度与 WHPPD 之间的相关性仅在总体水平上显著。加权 WHPPD 后，8 对配对单元的计划与实际 WHPPD 之间的差异减小。
使用加权因素来调整急性护理医疗外科单位的 WHPPD，可能有助于准确的人员配备计划和预算编制。
