A Descriptive Study of Elderly Patients With Dementia Who Died Wandering Outdoors in Kochi Prefecture, Japan

This was a descriptive study of elderly persons with dementia who were found dead after becoming lost in the community. Causes of death were drowning (n = 8), trauma (n = 5), hypothermia (n = 2), and debilitation possibly due to fatigue (n = 1) or were unknown (n = 3).

  1. List the Independent Variable(s).
  2. List the dependent variable(s)
  3. In your opinion how generalizable is this study? Why?
  4. How can this study help inform evidence based practice?

Here suppose the cause of death were drowning is any x variable= 8

Trauma is y variable=5

Hypothermia is z variable=2

Fatigue is u variable= 1 or 3

List of independent variable is x

List of dependent variable is u, y, z as the three deseases are occur when body temperature is low hence they are dependent

This study employed a retrospective descriptive design. Data were gathered from police investigative reports

The study has potential implications for enabling their early discovery and protection.

The causes of death were drowning (n = 8), trauma (n = 5), hypothermia (n = 2), debilitation possibly due to wandering fatigue (n = 1), or were unknown (n = 3). Drowning sites included the river , sea and pond and the probable cause of death in every instance was falling into the water while walking or driving. Deaths from trauma (n = 5) were caused by being hit by a vehicle and falling from high positions while walking at night. Two hypothermia cases occurred due to walking outdoors in low temperatures

.The mean age of men and women in our study was relatively close to the mean Japanese lifespan of 79.9 and 86.4 years for men and women, respectively. In general, patients with dementia who stay in a hospital or nursing home are less likely to become lost in the community. Probable reasons for the higher risk of such deaths among older adults with dementia living at home, compared with those staying in hospitals, include the increase in those living alone and the reduced capacity to care for these individuals in their homes due to the current trend toward nuclear families in Japan.

A study compared patients who suffered a heart attack in the daytime with patients who suffered a heart attack in the night.  Of 58,593 had a heart attack in the daytime 11,604 survived.  Of 28,155 who had a heart attack at night 4139 survived.  Use α = .01 and test the claim that the survival rates are the same.

An observational study of Alzheimer's disease (AD) obtained data from 14 AD patients exhibiting moderate dementia and selected a group of 9 control individuals without AD. AD is a progressive neurodegenerative disease of the elderly and advancing age is known to be a primary risk factor in AD diagnosis. Therefore, it was crucial for the study's credibility to examine whether the ages in the AD group might be significantly different than in the control group. The ages of the subjects...

A research study is comparing the aorta diameters of patients who have aortic disorders to the aortas of those who do not have any disorders. The aorta diameters of 15 cases (those with aortic disorders) were measured. The results are given below, measured in millimeters (mm): 7.22, 9.24, 12.01, 7.18, 9.17, 8.26, 14.03, 10.55, 11.09, 10.17, 8.56, 8.29, 7.87, 11.24, 13.14 a) Because the sample size is small, to compute a confidence interval for the mean, we must assume that...

A February study of about 1,000 patients in Wuhan, China, who were hospitalized with suspected coronavirus there, where the pandemic began, found that about 60% tested positive using lab tests similar to those available in the U.S. But, almost 90% showed tell-tale signs of the virus in CT scans of their chests, the article, published in the journal Radiology, found, suggesting many patients in the group were testing negative despite active coronavirus infections.” Here, the population is “patients hospitalized for...
