Introduction

Mortality and associated risk factors for older adults admitted to the emergency department: a hospital cohort

Background

Older emergency department patients are more vulnerable than younger patients, yet many risk factors that contribute to the mortality of older patients remain unclear and under investigation. This study endeavored to determine mortality and factors associated with mortality in patients over 60 years of age who were admitted to the emergency departments of two general hospitals in Mexico City.

Methods

This is a hospital cohort study involving adults over 60 years of age admitted to the emergency department and who are beneficiaries of the Mexican Institute of Social Security and residents of Mexico City.

All causes of mortality from the time of emergency department admission until a follow-up home visit after discharge were measured. Included risk factors were: socio-demographic, health-care related, mental and physical variables, and in-hospital care-related. Survival functions were estimated using Kaplan-Meier curves. Hazard ratios (HR) were derived from Cox regression models in a multivariate analysis.

Results

From the 1406 older adults who participated in this study, 306 (21.8%) did not survive. Independent mortality risk factors found in the last Cox model were age (HR = 1.02, 95% CI, 1.005–1.04; p = 0.01), length of stay in the ED (HR = 1.003, 95% CI = 0.99, 1.04; p = 0.006), geriatric care trained residents model in Hospital A (protective factor) (HR = 0.66, 95% CI = 0.46, 0.96; p = 0.031), and the FRAIL scale (HR of 1.34 95% CI, 1.02–1.76; p = 0.033).

Conclusions

Risk factors for mortality in patients treated at Mexican emergency departments are length of stay and variables related to frailty status.

Association of Healthy Habits Beliefs and Mortality in Older Adults: A Longitudinal Analysis of the Mexican Health and Aging Study

OBJECTIVE

The aim of this article is to establish the association between beliefs about healthy habits and mortality in a group of Mexican older adults.

METHOD

This is an 11-year follow-up secondary analysis of the Mexican Health and Aging Study.

RESULTS

There was a significant difference ( p < .001) in survival rate between those participants who believed that healthy habits have the potential to improve health compared with those who did not. After adjustment for confounders, Cox regression models showed a hazard ratio (HR) of 0.17 (95% confidence interval [CI] [0.07, 0.38], p < .001) for the group that believed in healthy habits.

DISCUSSION

Although the mechanism is not completely clear, according to our results, believing that healthy habits can improve health was associated with lower rates of mortality. Further research should elucidate potential strategies for changing beliefs in older adults with the goal of improving their overall health.

Collective violence and the health of the elderly: a cross-sectional analysis of a population-based national survey in Mexico

OBJECTIVE

To describe the association between collective violence and the health of older adults in Mexico.

METHODS

The data analyzed were taken from a Mexican population-based national survey of health and nutrition that included a representative sample of adults over 60 years of age and from an index of violence for each of the states of Mexico that was compiled by a major research center. Five of the most common geriatric ailments (weight loss, depressive symptoms, falls, positive affectivity, and disability) were crossed with the violence index score assigned to each state.

RESULTS

A total of 7 108 older adults were included in the analysis. Among the five geriatric health problems, weight loss had the strongest association with violence, even when an adjusted model was used. For weight loss, that association increased as the level of collective violence rose. With the adjusted model, there was also an association of severe collective violence with disability and with low positive affectivity.

CONCLUSIONS

Our results show that there is an association of collective violence with weight loss and other geriatric problems. Collective violence could indirectly affect individuals' health, especially older persons and other vulnerable groups.
