Hypothesis
The study aims to assess the impact of cognitive impairment on mortality and hospital outcomes in older patients.
Conclusion
Malnutrition, pneumonia, and cancer significantly decrease survival rates in patients with cognitive impairment at admission.
Supporting Evidence
- 349 patients (57.0%) died during follow-up.
- Cognitive impairment was associated with increased mortality hazard.
- Malnutrition, pneumonia, and cancer were identified as significant risk factors.
Takeaway
Older patients with memory problems are more likely to die from other health issues like malnutrition and pneumonia.
Methodology
The study used Kaplan-Meier method and Cox’s proportional hazards regression models to analyze mortality and survival rates.
Participant Demographics
Mean age was 82.1 years, with 55.9% female participants.
