The Minnesota Department of Health has cited a Cold Spring nursing home for neglect in the death of a resident whose head became lodged between a mattress and bedrail. The department said Wednesday that staff at Assumption Home failed to conduct a required assessment of the resident to determine whether a bed railing was needed. The resident had a history of dementia and falls. Authorities say the resident’s neck became lodged between the rail and mattress sometime between a nursing check and when the resident was found 40 minutes later. The resident died of asphyxiation in January. Assumption has since implemented new safety measures. State Health Commissioner Ed Ehlinger hopes the death will motivate nursing homes to review their use of bedrails.
