RESUMEN
Objective To develop a observation table with influencing factors for catheter-associated urinary tract infections in critical patients and verify its reliability and validity. Methods Literature review, brainstorming method, expert interview and group discussion were performed to identify items of the form. By convenience sampling method, totally 130 severe patients with urinary catheter were investigated by this scale. This form was evaluated by item analysis, exploratory factor analysis and reliability and validity test. Results The observation table with influencing factors for Catheter-associated Urinary Tract Infections in critical patients consisted of five dimensions and 26 items. The cumulative contribution of variance was 73.752%, the Cronbach′s alpha coefficient was 0.869 and the Spearman-Brown split-half coefficient was 0.828. Regarding to the construct validity, the correlation coefficient between the each factor and total observation table was 0.652~0.873, the correlation coefficient between the factors was 0.311~0.823. All the difference of correlation coefficients were statistically significant (P<0.01). Conclusions The observation table with influencing factors for Catheter-associated Urinary Tract Infections in critical patients has been proved to be reliable and valid. It can be used as a valid tool to assess influencing factors for Catheter-associated Urinary Tract Infections in critical patients.
RESUMEN
The character of intensive care unit(ICU) makes ICU a chlinical teaching base and plays an important role in medical teaching.By learning from ICU,students can understand and remember basic medical curriculum easily,form their global concept,cultivate their clinical thinking habit,promote their ability of emergency treatment,culture their idea of innovation,and help theim to revere life which is thought as the central idea of medical moral principles.It is worth paying attention to strengthen ICU construction and to properly utilize teaching resource of ICU.
