Hypothesis
What are the consequences of falling and the use of call alarm systems among people aged over 90?
Conclusion
Lying on the floor for a long time after falling is more common among the oldest old than previously thought and is associated with serious consequences.
Supporting Evidence
- 54% of fall reports described the participant as being found on the floor.
- 82% of falls occurred when the person was alone.
- 80% of those who fell were unable to get up after at least one fall.
- 30% had lain on the floor for an hour or more.
- Lying on the floor for a long time was strongly associated with serious injuries and hospital admissions.
- Call alarms were widely available but not used in most cases of falls.
Takeaway
When older people fall and can't get up, they often end up lying on the floor for a long time, which can be very dangerous. Many have alarms to call for help, but they often don't use them.
Methodology
The study followed participants for one year, collecting data on falls through calendars, phone calls, and visits.
Potential Biases
Potential recall bias from participants and proxies regarding fall incidents.
Limitations
The study relied on participant and proxy reports, which may lead to underreporting or misreporting of falls and their consequences.
Participant Demographics
90 women and 20 men aged over 90, predominantly frail with varying levels of cognitive impairment.
