BACKGROUND

length of stay (LOS) is the time between hospital admission and discharge. LOS has an impact on hospital management and hospital care functions.

METHODS

A descriptive, retrospective study was designed on about 27,500 inpatients between March 2019 and 2020. Required data were collected from six wards (CCU, ICU, NICU, General, Maternity, and Women) in a teaching hospital. Clinical data such as demographic characteristics (age, sex), type of ward, and duration of hospital stay were analyzed by the R-studio program. Violin plots, bar charts, mosaic plots, and tree-based models were used to demonstrate the results.

RESULTS

The mean age of the population was 40.8 ± 19.2 years. The LOS of the study population was 2.43 ± 4.13 days. About 60% of patients were discharged after staying one day in the hospital. After staying one day in the hospital, 67% of women were discharged. However, 23% of men were discharged within this time frame. The majority of LOS in the CCU, ICU, and NICU ranged from 5 to 9 days.; In contrast, LOS was one day in General, Maternity, and Woman wards. Due to the tree plot, there was a different LOS pattern between Maternity-Women and the CCU-General-ICU-NICU wards group.

CONCLUSION

We observed that patients with more severe diseases hospitalized in critical care wards had a longer LOS than those not admitted to critical care wards. The older patient had longer hospital LOS than the younger. By excluding Maternity and Woman wards, LOS in the hospital was comparable between males and females and demonstrated a similar pattern.

背景

住院时间（LOS）是指从住院到出院的时间。 LOS 会影响医院管理和医院护理功能。

方法

设计了一项描述性、回顾性研究，纳入了 2019 年 3 月至 2020 年期间约 27500 名住院患者。从一家教学医院的六个病房（CCU、ICU、NICU、普通、产科和妇科）收集所需数据。使用 R-studio 程序分析人口统计学特征（年龄、性别）、病房类型和住院时间等临床数据。使用小提琴图、条形图、镶嵌图和基于树的模型来展示结果。

结果

研究人群的平均年龄为 40.8±19.2 岁。研究人群的 LOS 为 2.43±4.13 天。约 60%的患者在住院一天后出院。在住院一天后，67%的女性出院。然而，在这段时间内，只有 23%的男性出院。CCU、ICU 和 NICU 中的大多数 LOS 范围在 5 到 9 天之间；相比之下，普通、产科和妇科病房的 LOS 为一天。由于树图，产科-妇科与 CCU-普通-ICU-NICU 病房组之间存在不同的 LOS 模式。
