If you have no close support, arrange practical checks through a trusted neighbor, community services, and emergency contacts

No charge to ask. The difficult part is telling a neighbor or community committee that you live alone and have just experienced a major loss.

REACH followed 44,573 outpatients from multiple countries with atherothrombotic disease or risk factors—conditions involving arterial plaque and a tendency for blood clots to obstruct vessels. Participants enrolled from December 2003 through December 2004 and were followed for four years; 8,594, or 19%, lived alone. Four-year all-cause mortality was 14.1% for those living alone versus 11.1% for those living with others, and cardiovascular mortality 8.6% versus 6.8%, both log-rank P<0.01. The association differed by age, interaction P=0.03. At ages 45–65, mortality was 7.7% versus 5.7%, adjusted HR 1.24, 95% CI 1.01–1.51. At ages 66–80 it was 13.2% versus 12.3%, HR 1.12, 1.01–1.26. Above 80 it was 24.6% versus 28.4%, HR 0.92, 0.79–1.06, without a clear increase. China's 2022 ten-department guidance requires outreach and care services for older people living alone, in empty-nest or left-behind households, with care needs or severe disabilities, and in specified family-planning hardship households. Methods include home visits, telephone or video contact, and remote monitoring. Township or subdistrict authorities, assisted by village or neighborhood committees, identify residents, record willingness to receive services, and include them in local grid-based support. By the end of 2025, the target was monthly contact with 100% of older people in special difficulty and at least one monthly visit or care contact for those unable to care for themselves. The guidance encourages smart call systems, electricity and water meters, health monitors, and eldercare devices that alert emergency contacts when abnormalities arise. Staff discovering an emergency should immediately help call for urgent assistance.

First, agree on a spare key or temporary door code with a trusted neighbor or appropriate property-management contact and explain that you will be alone. They need not be a close friend, but access to your home should be entrusted carefully. Second, tell the neighborhood committee and ask about outreach eligibility and any locally funded call devices or smart meters. Older people living alone, in empty nests, or who have lost their only child are specified groups. Third, set emergency contacts and medical emergency information on your phone; avoid leaving it off or inaudible during this period. Evidence is B because living-alone data are observational and may reflect pre-existing health or social disadvantage; the authors themselves call for confirmation. The outreach policy also concerns older people, not a dedicated scheme for everyone under 60. Community workers are nonetheless asked to identify psychological crises associated with family changes, unemployment, or leaving education; see entry 11 and China's 12356 psychological support line. Chapter 13, entry 1 explains why timely discovery matters: in its cited data, 79.2% of out-of-hospital cardiac arrests occurred at home, and survival to discharge was 16.1% with bystander CPR versus 3.9% without. Being alone can delay help, though those rates are not direct estimates of the effect of living arrangements. Funeral and account procedures in chapter 25—visits to the funeral home, community health service, police, and housing provident fund office—can provide a manageable daily reason to leave home. Helplines such as 12356 can be called more than once. Longer-term living-alone mortality associations, including OR 1.32, are discussed in chapter 22, entry 10; this entry focuses on the immediate days.
