Topic: Risk, prevention and care in population studies

Plain-language summary

Of the 258 surveyed doctors, 74 (28.7%) practiced ACP. Multiple logistic regression identified that age 20-49 years and experience in treating (or visiting facilities to treat) patients with COVID-19 infection were factors related to doctors that were significantly and positively associated with ACP practice. Additionally, a significant decline in the patients' cognitive functions and difficulties in preventing COVID-19 infection were positively associated with ACP practiced by doctors. This study suggested that ACP should be practiced for older patients with dementia before COVID-19 infection, which would worsen their dementia symptoms. Moreover, ACP should be emphasized for older patients admitted to facilities. Our results could help devise effective measures to facilitate ACP practices.

What this study adds

Evidence grade: Low

This is a cross-sectional study of 19 participants. It suggests advance care planning should be practised for older patients with dementia before COVID-19 infection worsens their symptoms. Reported effect size: 28.7%.

How to read this study

Design: this is a cross-sectional study. Everyone is measured once, so it cannot show which came first. Read it as a snapshot of how two things go together at one moment.
Size: the record lists 19 participants. Ask whether that is enough for the question, and who they were.
Effect: the record reports “28.7%”. A statistically significant result can still be small in daily life.

What the evidence grade means here

This page is graded low. alzhub.org assigns the grade automatically from keywords in the abstract, not from reading the paper. Low means the abstract matched neither pattern. It is the default label, and it does not mean the work is poor; many sound lab and imaging papers land here. It can add at most 5 of the 100 points in the study score, and it is a label about design, not a verdict on whether the findings are true.

Key findings

Of the 258 surveyed doctors, 74 (28.7%) practiced ACP.
Multiple logistic regression identified that age 20-49 years and experience in treating (or visiting facilities to treat) patients with COVID-19 infection were factors related to doctors that were significantly and positively associated with ACP practice.
Additionally, a significant decline in the patients' cognitive functions and difficulties in preventing COVID-19 infection were positively associated with ACP practiced by doctors.
This study suggested that ACP should be practiced for older patients with dementia before COVID-19 infection, which would worsen their dementia symptoms.
Moreover, ACP should be emphasized for older patients admitted to facilities.

Why it matters

This cross-sectional survey found that 28.7% of surveyed doctors in Japan practised advance care planning during the COVID-19 outbreak, with practice associated with doctor age 20-49 years, experience treating COVID-19 patients, patients' declining cognitive function, and difficulty preventing COVID-19 infection. It suggests advance care planning should be practised for older patients with dementia before COVID-19 infection worsens their symptoms.
