BACKGROUND: Patient safety critically influences both quality of life and disease progression in older adults with cognitive impairment, yet large-scale multicenter data remain scarce. This study aims to systematically analyze the types of safety incidents experienced by patients with Alzheimer’s disease and related cognitive impairments, and explore the network associations of different safety incidents.
METHODS: Initiated by the Alzheimer's Disease China (ADC), this survey recruited 1057 older individuals with Alzheimer’s and related cognitive impairments, along with their families, across 31 provinces, autonomous regions, and municipalities. The safety incidents evaluated in this study included falls, getting lost, medication errors, verbal aggression, physical aggression, household fire, aspiration, and choking. Incidence rates for overall and specific safety incidents were calculated. Correlation analyses and network analysis were performed to examine relationships between safety incidents.
RESULTS: A high proportion (73.5%) of participants reported at least one safety incident in the past year, with over one-third (36.0%) experiencing three or more concurrent incidents. Medication errors (55.9%) and verbal aggression (39.6%) were most frequent, followed by falls (32.5%) and physical aggression (22.7%). Incidence rates varied significantly by cognitive impairment stage, care setting, and geographic region. Network analysis highlighted medication errors and getting lost as central nodes bridging other incidents.
CONCLUSIONS: This study reveals an alarmingly high incidence of safety incidents among cognitively impaired patients, affecting their physical, psychological, and familial well-being. A collaborative, multidisciplinary effort involving healthcare professionals, family caregivers, fire and police emergency responders, and public health policymakers is essential to develop individualized safety strategies aligned with patient needs and contextual considerations.
