Half of nursing home residents (NHR) suffer from dementia. End-of-life hospitalizations are often burdensome in residents with dementia. A systematic review was conducted to study the occurrence of hospitalizations at the end of life in NHR with dementia and to compare these figures to NHR without dementia. A systematic literature search in MEDLINE, CINAHL and Scopus was conducted in May 2018. Studies were included if they reported proportions of in-hospital deaths or hospitalizations of NHR with dementia in the last month of life. Two authors independently selected studies, extracted data, and assessed quality of studies. Nine hundred forty-five citations were retrieved; 13 studies were included. Overall, 7 studies reported data on in-hospital death with proportions ranging between 0% in Canada and 53.3% in the UK. Studies reporting on the last 30 days of life (n = 8) varied between 8.0% in the Netherlands and 51.3% in Germany. Two studies each assessed the influence of age and sex. There seem to be fewer end-of-life hospitalizations in older age groups. The influence of sex is inconclusive. All but one study found that at the end of life residents with dementia were hospitalized less often than those without (n = 6). We found large variations in end-of-life hospitalizations of NHR with dementia, probably being explained by differences between countries. The influence of sex and age might differ when compared to residents without dementia. More studies should compare NHR with dementia to those without and assess the influence of sex and age.

老年痴呆症疗养院居民临终时的住院治疗：系统评价

一半的疗养院居民（NHR）患有痴呆症。临终住院对于患有痴呆症的居民来说通常是沉重的负担。进行了系统的回顾，以研究患有痴呆症的NHR生命终结时的住院发生率，并将这些数字与没有痴呆症的NHR进行比较。2018年5月在MEDLINE，CINAHL和Scopus进行了系统的文献检索。如果研究报告了生命的最后一个月院内死亡或因痴呆而住院的NHR的比例，则纳入研究。两位作者独立选择研究，提取数据并评估研究质量。检索到945条引用；包括13项研究。总体而言，有7项研究报告了院内死亡数据，其比例在加拿大为0％，在英国为53.3％。报告生命中最后30天（n = 8）的研究在荷兰的8.0％和德国的51.3％之间变化。两项研究均评估了年龄和性别的影响。在老年组中，临终住院的人数似乎较少。性的影响尚无定论。除一项研究外，所有研究均发现，患有痴呆症的居民在住院时的住院频率要低于没有痴呆症的居民（n = 6）。我们发现，患有痴呆症的NHR的临终住院治疗差异很大，这可能是由于国家之间的差异所致。与没有痴呆症的居民相比，性别和年龄的影响可能有所不同。更多的研究应该将NHR和痴呆与没有痴呆的人进行比较，并评估性别和年龄的影响。PROSPERO注册号CRD42018104263。
