Risk factors for delirium among older hospital patients: a systematic review and meta-analysia / 中国实用护理杂志

ABSTRACT

Objective To confirm the correlation between general information、physical functioning and delirium among elderly patients in medical units by systematic review and meta-analysis. Methods With strictly designed search strategies, electronic databases as follows CBM, CNKI, VIP, WanFang, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Embase, MEDLINE, MEDLINEIn-Process & Other Non-Indexed Citations(OVID), PsycInFo, CINAHL (EBSCO), SCI(Web of Science)were searched dated from the database building to October 2015.Two researchers confirmed the included studies according to the inclusion and exclusion criteria, evaluated the methodological quality of studies and extracted data independently. The Revman 5.3 was used for data analysis. Results (1) Ageresults reported indichotomous,combined OR=2.57 (95％CI1.69-3.89), P<0.00001;results reported in continuous,combined MD=2.67 (95％CI1.57-3.77), P< 0.01.(2) MaleOR=1.34 (95％CI0.91-1.97),P=0.14;inverse variance, OR=1.11(95％CI0.95-1.30), P=0.20. (3)Activities of daily living OR=2.66 (95％CI1.90-3.70),P< 0.01. (4)Vision impairment combined OR=2.31 (95％CI1.24-4.32), P = 0.009.(5) Physical restraints OR=6.60(95％CI4.22-10.31), P < 0.01. Conclusions Physical restraintsis correlative with delirium among elderly patients in medical units. Age, vision impairment, activity of daily living may be correlative with delirium among elderly patients. We suggest to pay attention to those factors to implement delirium prevention, treatment and nursing to reduce the incidence and improve clinical outcomes for elderly patients.
