Home Selfcare Behavior After Total Knee Arthroplasty Patients*

Abstract

This survey research aimed to describe the home self-care behaviour after total knee
arthroplasty patients of Siriraj Hospital. The PRECEDE Framework was applied in the research
conceptual framework and the concept of Social Support, Social Cognitive Theory, Health Belief
Model, and self-care were applied to determine the research variables. With regards to the survey
research, the sample included 253 patients who had total knee arthroplasty surgery at Siriraj
Hospital and returned to their homes for at least 1 month to 12 months. Interview questionnaires
were used for data collection, and data analysis was done by using the following statistics:
frequencies, percentages, means, standard deviation, Chi-square test, Pearson's Product-Moment
Correlation and multiple linear regression analysis.
It was found that 75.5 percent of the patients had a “good" level of self-care behaviour
after total knee arthroplasty while 24.1 percent had a “moderate” and 0.4 percent had a “not
good or should be improved” level. The education, knowledge, self-efficacy, perceived
susceptibility to complications, social support from relatives and the availability of equipment in
the post-operative care period was positively and significantly related to self-care behaviour of
patients (p<0.05) while age and environment at home were negatively related to self-care
behaviour of patients (p<0.05). However, social support from relatives, self-efficacy, the
availability of equipment in post-operative care, education and knowledge could have predicted
self-care behaviour of patients at the level of 67.8 percent. These research results can be utilized
as the baseline data for any hospital in managing the post-operative care system, and promote
self-care behavior at home which will lead to better quality of life.
