Background: Urinary tract infections are a common iatrogenic infection in healthcare institutions. Catheter-associated urinary tract infections (CAUTIs) may result in sepsis, prolonged hospitalization, additional hospital costs, and mortality.
Purpose: The study examined the efficacy of an indicator-based reminder of catheter removal in decreasing CAUTIs among patients in the general medical ward.
Methods: A two-group, quasi-experimental design was used. The intervention strategies included daily implementation of the indicator-based reminder procedure and standardized Foley care and a teaching program for all staff nurses. All patients who received Foley during hospitalization were included, with the exception of those with CAUTI at admission. Seventy-five patients were enrolled from five wards in a medical center, with 33 assigned to the control group and 42 assigned to the experimental group.
Results: CAUTIs were diagnosed in 7 participants (16.7%) in the experimental group and 15 participants (45.5%) in the control group. The differences were statistically significant (p = .014). The mean number of Foley days was 14.73% less in the experimental group, with 11.0 for the experimental group and 12.9 for the control group. The incidence density of CAUTIs was 15.2% for the experimental group and 35.3% for the control group.
Conclusions: The present study supports that an indicator-based reminder of catheter removal decreases the incidence rate and incidence density of CAUTIs. Medical personnel in the general medical ward may use this reminder to detect unnecessary indwelling of urinary catheters and to remove Foley catheters as early as feasible in order to prevent CAUTIs.
結果: 實驗組發生泌尿道感染人數為7人（16.7%），對照組為15人（45.5%）此差異達顯著（p = .014）；實驗組導尿管留置天數11.0天，對照組12.9天，實驗組導尿管留置天數較控制組減少14.73%；實驗組感染密度為15.2%，對照組感染密度則為35.3%。.
