Factors associated with falls in frail older persons—a case control study in Brazil
Method
This is a case-control study paired by sex and age, with the cases defined as frail older persons with self-reported falls in the last year and controls as frail older persons with no fall report. Odds ratio (OR) was analyzed by means of conditional logistic regression, with a 95% confidence interval. Main outcome measure: The occurrence of falls in frail older persons is associated with the following clinical and pharmacoepidemiological factors: urinary incontinence and polypharmacy.
Results
The sample consisted of 1028 older persons, 514 in the case group and 514 in the control group. The prevalence of falls was 26.5%. The frequency of polypharmacy, use of drugs inappropriate according to Beers’ criteria and drugs that increase the risk of falls were 58%, 85% and 87%. The frequency of drugs with anticholinergic properties ranged from 12 to 65% according to the type of scale used. It was observed that the fall is associated with urinary incontinence (OR 1.73, 95% CI 1.28–2.34) and use of five or more medications (OR 1.68, 95% CI, 1.30–2.17).
Conclusions
With this research, is possible to conclude that falling in the frail older persons is associated with the use of five or more drugs and the presence of urinary incontinence.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
