intervention of program P-LEA (n = 30)

(MCC-García)
3.1.1 Disease process (NOC) indicator
Prior to the educational intervention, less than half of caregivers displayed substantial knowledge of the disease process indicator. Immediately following the P-LEA program,
knowledge increased to extensive in more than three fourths
of caregivers. In the second measurement following the
instructional intervention, knowledge was increased by 10%.
3.1.2 Precautions to prevent treatment complications
(NOC) indicator
Slightly more than half of caregivers displayed substantial
knowledge with regard to precautions for preventing treatment complications prior to the implementation of the P-LEA
program. Following the implementation of the program, overall knowledge increased to extensive knowledge, and this
level was maintained in the second measurement following
the instructional intervention.
3.1.3 Adverse effects of medication (NOC) indicator
Less than half of caregivers displayed substantial knowledge
prior to the implementation of the P-LEA program, and in
the first measurement following the implementation of this
knowledge, the majority of caregivers increased to extensive
knowledge, which was maintained in the second measurement following the program.
Statistical analysis was performed using Student’s t test for
paired samples. In the pre-intervention group instruction,
the mean was 16.6 (95% CI, SD 3.9). In the first measurement post-group instruction intervention, a mean of 25.53
was obtained, with an SD of 1.9 and a CI of 95%. In the
second measurement post-intervention, a mean of 25.27 with
an SD of 4.9 and a 95% CI was obtained. The means for
the measurements pre-intervention and first post-group instruction intervention differed significantly (p = .000). The
average scores obtained pre-intervention were different from
those obtained in the first measurement post-intervention (p
= .000). The difference between the second measurement
and the third one was not significant (p = .782)
