Abstract

Purposes

To evaluate the incidence of unintended tube, line, and drain removals (UTRs) in our ICU, to identify system factors associated with UTRs, and to evaluate interventions designed to decrease UTR occurrence.

Methods

Interventional study in the 18-bed medical ICU of a French general university hospital. We prospectively determined the incidence and circumstances of UTRs in our ICU over a 2-year period. Demographic and clinical data were collected for consecutively admitted patients, and additional information was recorded about patients experiencing UTRs. Investigators analyzed UTR data twice a month to identify possible causes and developed interventions to decrease UTRs (mainly securing tubes and sedation protocol). Conditional logistic regression stratified on length of stay was used to identify risk factors for UTRs and segmented linear regression analysis to test the effects of interventions.

Results

Of 2,007 admitted patients (12,256 patient days), 193 (9.6%) experienced 270 UTRs (22/1,000 patient days). Clinical or therapeutic consequences occurred for 17% of UTRs. Three factors were independently associated with UTR; two were risk factors, namely, admission for coma [OR, 2.68; 95% CI (1.87; 3.84); P < 0.0001] and mechanical ventilation in over 65% of all ICU patients [OR = 1.65 (1.19; 2.29); P = 0.003], and one was protective, namely, mean SAPS II >45 in all ICU patients [OR, 0.54; 95% CI (0.39; 0.75); P = 0.0003]. Segmented regression analysis showed a 67.4% drop [95% CI (17.2%; 117.3%); P = 0.009] in the UTR rate after the first intervention was introduced. System factors played a major role in UTR occurrence.

Conclusion

UTRs are common. A continuous quality-improvement program can reduce UTR rates in the ICU.
