目的

评价住院病人使用口服营养补充剂对住院时间长度、费用以及30天内再次入院概率的影响.

Study Design: Eleven-year retrospective study (2000 to 2010).

实验设计

11年回顾性研究(2000到2010年)

Methods: Analyses were conducted using the Premier Perspectives Database, which contained information on 44.0 million adult inpatient episodes. Using a matched sample of ONS and non-ONS episodes for any inpatient diagnosis, instrumental variables regression analysis was performed to quantify the effect of ONS use on length of stay, episode cost, and probability of approximate 30-day readmission.

试验方法

此次研究使用的是Premier Perspectives数据库.其中包含了44,000,000个成年住院病人的数据.该实验把使用了口服营养补充剂和未使用口服营养补充剂的住院病人一一配对.试验中使用了辅助变量回归分析来量化口服营养补充剂对住院时间长度、费用及30天内再次入院概率的影响.

Results: Within the database, 1.6% of 44.0 million adult inpatient episodes involved ONS use. Based on a matched sample of 1.2 million episodes, ONS patients had a shorter length of stay by 2.3 days (95% confidence interval [CI] – 2.42 to –2.16), from 10.9 to 8.6 days (21.0% decline), and decreased episode cost of $4734 (95% CI – $4754 to – $4714), from $21,950 to $17,216 (21.6% decline). ONS patients had a reduced probability of early readmission (within 30 days) of 2.3 percentage points (95% CI – 0.027 to – 0.019), from 34.3% to 32.0% (6.7% decline).

结果

根据此数据,1.6%的住院病人使用了口服营养补充剂.根据配对的1,200,000对样本,使用口服营养补充剂的患者平均住院日在10.9到8.6天,比没有服用口服营养补充剂的患者缩短了2.3天.使用了口服营养补充剂的患者的平均住院费用在21,950到17,216美元,比未使用者减少了4734美元.使用口服营养补充剂的病人,30天内再次入院的概率为34.3%到32.0%(降低了2.3%).

Conclusions: Use of ONS decreases length of stay, episode cost, and 30-day readmission risk in the inpatient population.

结论

使用口服营养补充剂可以降低住院时间长度,住院费用,以及30天内再次入院的概率.
