title: The effects of various instructional methods on retention of knowledge about pressure ulcers among critical care and medical-surgical nurses.
abstract: BACKGROUND
  To determine whether there was a difference in retention of knowledge about pressure ulcers with a traditional lecture versus computer-based instruction.
  
  
  METHODS
  A quasi-experimental, pretest/posttest design was used. Medical-surgical and critical care nurses (N = 60) were randomly assigned to a lecture, to computer-based instruction, or to a control group. Study participants were given the pressure ulcer knowledge test before and immediately after the program and at 3-month and 6-month intervals.
  
  
  RESULTS
  Analysis of variance showed statistically significant differences in pretest and posttest scores [F(2, 57) = 35.784, p = .000] and in posttest to 3-month scores [F(2, 57) = 18.427, p = .000] among the three groups.
  
  
  CONCLUSIONS
  The most significant loss of pressure ulcer knowledge, regardless of educational method, occurred within the first 3 months. Based on these findings, quarterly education in pressure ulcer prevention is recommended to maintain knowledge. Computer-based instruction is a viable option for acquisition and retention of knowledge about pressure ulcer prevention.
