Abstract：
BACKGROUND: Little is known about the prevalence of malnutrition among patients receiving home care (HC) and ambulatory care (AC) services. Further, the risk of hospital readmission in malnourished patients transitioning from hospital to HC or AC is also not well established. This study aims to address these two gaps.
METHODS: A descriptive cohort study of newly referred HC and AC patients between January and December 2019 was conducted. Nutrition status was assessed by clinicians using the Mini Nutritional Assessment-Short Form (MNA-SF). Prevalence of malnutrition and at risk of malnutrition (ARM) was calculated, and a log-binomial regression model was used to estimate the relative risk of hospital readmission within 30 days of discharge for those who were malnourished and referred from hospital.
RESULTS: A total of 3704 MNA-SFs were returned, of which 2402 (65%) had complete data. The estimated prevalence of malnutrition and ARM among newly referred HC and AC patients was 21% (95% CI: 19%-22%) and 55% (95% CI: 53%-57%), respectively. The estimated risk of hospital readmission for malnourished patients was 2.7 times higher (95% CI: 1.9%-3.9%) and for ARM patients was 1.9 times higher (95% CI: 1.4%-2.8%) than that of patients with normal nutrition status.
CONCLUSIONS: The prevalence of malnutrition and ARM among HC and AC patients is high. Malnutrition and ARM are correlated with an increased risk of hospital readmission 30 days posthospital discharge.

摘要：
背景：关于接受家庭护理（HC）和非卧床护理（AC）服务的患者中营养不良的患病率知之甚少。Further,从医院转行HC或AC的营养不良患者的再入院风险也未得到很好的确定.本研究旨在解决这两个差距。
方法：对2019年1月至12月新转诊的HC和AC患者进行了描述性队列研究。临床医生使用迷你营养评估简表（MNA-SF）评估营养状况。计算了营养不良和营养不良风险（ARM）的患病率，使用对数二项回归模型估计营养不良患者出院后30天内再入院的相对风险.
结果：总共返回了3704个MNA-SF，其中2402人（65%）有完整的数据。新转诊的HC和AC患者中营养不良和ARM的估计患病率为21％（95％CI：19％-22％）和55％（95％CI：53％-57％），分别。营养不良患者的估计再入院风险比营养状态正常患者高2.7倍（95％CI：1.9％-3.9％），ARM患者的估计再入院风险高1.9倍（95％CI：1.4％-2.8％）。
结论：HC和AC患者中营养不良和ARM的患病率较高。营养不良和ARM与出院后30天再次入院的风险增加相关。
