the education program but still remained far below the
recommended 30 s (Table 2). Changes in drying time prior
to patient contact in comparison with the previous
observation periods were +60% (pretest 1 vs. pretest 2),
+50% (pretest 2 vs. posttest 1) and 33% (posttest 1 vs.
posttest 2) (Table 2). Changes in drying time after patient
contact were comparable to those.
The median (IQR) amount of hand alcohol solution used
had increased by 35% after the education program; 40 (25–
56) vs. 54 mL/day/patient (40–71), p < 0.001.
