Introduction
Catheter-associated urinary tract infection (CAUTI) is a fairly common complication in hospitalized patients. Nosocomial infection prevention and patient safety promotion has been issued and many researches have been conducted to improve patient’s quality of life. In this article, Saint et al. (2005) hypothesize that using a paper-based urinary catheter reminder can reduce the incidence of urinary catheterization, and consequently this will enhance the patients’ safety.
Critique Part 1 Research Questions or Hypotheses The background and significance of this study are properly presented in the introduction. The research question is presented at the end of the introduction of this article. Saint et al. (2005) develop the research question based on the scientific backgrounds they selected and reviewed: “Is a urinary catheter reminder effective in reducing the incidence of indwelling urethral catheterization in the hospitalized patients?” (p. 456). The Independent variable is “a urinary catheter reminder” and the dependent variable is “the incidence of indwelling urethral catheterization.” The research question appropriately states the relationship between “a urinary catheter reminder” and “the incidence of indwelling urethral catheterization,” thus the research question is specific to one relationship. The research question is generated from PICO information which means population, intervention, comparison, and outcome (LoBiondo-Wood & Haber, 2010, p. 63). In this study, population is the hospitalized patients in the University of Michigan Medical Center and a total of 5,678 patients participate in the study. Intervention is ‘using’ a catheter reminder and comparison is ‘not using’ a catheter reminder. Outcome is the effectiveness of a use of the reminder. Although hypothesis is not directly written in the article, Saint et al. (2005) imply that a paper-based reminder of indwelling
