Data on a sample of 890 Veteran's Administration long-staying psychiatric patients were studied to develop a classification system that explains actual daily resource use. Disturbed patients with lengths of stay of less than three years and those with psychotic conditions who are not withdrawn represent the two groups found to use significantly more resources in their daily care. The Long-Stay Psychiatric Patient Classification (LPPC) System, with six categories, explains 11.4% of the variability in per diem resource use and can be used for case-mix adjustment of payments for psychiatric care.
对890名退伍军人管理局长期住院精神科患者的样本数据进行了研究，以开发一种能够解释实际日常资源使用情况的分类系统。住院时间少于三年的精神障碍患者以及未出现退缩症状的精神病患者，是在日常护理中发现使用资源明显更多的两类患者。长期住院精神科患者分类（LPPC）系统有六个类别，可解释每日资源使用差异的11.4%，并可用于精神科护理费用的病例组合调整。
