Study designs of evaluations included in the review
Randomised controlled trials (RCTs) and quasi-experimental studies were eligible. The minimum standard for design of study to be included in the review was a before-and-after design; all the included studies were of this limited design.
Specific interventions included in the review
Studies of formalised bandaging training were eligible. In one of the included studies the training comprised a single training day, and in another a 4-hour workshop. Details of the training in the third study were not given.
Participants included in the review
Nurses who performed compression bandaging were eligible. In all of the included studies the nurses were self selected. In one study the level of experience in bandaging varied, in another the nurses routinely undertook compression bandaging, and in the third they had previously received specialist training in bandaging. The nurses in the included studies were district or community nurses, student nurses or dermatology nurses.
Outcomes assessed in the review
Studies that appraised nurses' bandaging techniques were eligible; this was any objective measure of compression on a patient's limb using a competency-based system to rate the individual's skills. In all of the included studies the outcome measure was the pressure measured at three separate points on the lower leg. Studies using outcomes remote from the direct assessment of technique, such as those related to the healing of ulcers, were excluded.
