The study was designed to test the effectiveness of a homebased diet education for the patients with chronic liver disease.
On reviewing the literature it became evident that among all possible contributing factors, the importance of nutrition stands out particularly, acting simultaneously as the cause and effect of liver disease. Thus, the study was carried out under the assumption that the education and consequencial adherence to a specially planned therapeutic diet by patients with chronic liver diseases will bring improvement in their progress and prognosis as measured by liver function tests.
The study was designed as a pre-post comparison on liver function tests between the experimental and control groups with a systematic homebased diet education as the experimental intervention.
Subjects for the study were patients discharged from three university hospitals in Seoul from April 1, 1987 to May 31, 1987. A total of 60 patients who met the criteria of selection agreed to participate in the study. At the conclusion of study, 17 out of 20 in the experimental group had achieved an 80% adherence level to a speicfied diet regime and yielded effective data for final analysis.
Data were collected at 4 week intervals following pre-experimental assessment with diet education as the experimental input, and the results were compared between the experimental and control groups. For six months, from April, 1987 to September, 1987, a biweekly visit for 12 weeks with each patient was made for the purpose of education, monitoring, and consultation.
Findings from the analysis of the data yielded by those 17 in the experimental group as compared with the data on the 31 subjects in the control group confirmed the basic assumption, and the hypotheses were supported by showing a significant difference between groups at the 5% level for the values of serum albumin, SGOT, and SGPT. Thus, it is concluded that homebased nursing interventions with special emphasis on diet education is effective improving the condition of patients with chronic liver diseases.
In addition, the time series analysis revealed the fact that the effect of the dietary intervention did not appear as significant until 12 weeks after the initial diet education for serum albumin and SGOT values. The value of SGPT showed a significant change starting at the 8th week following the initial dietary intervention with an even greater change noticed at 12 weeks. Thus, it can be concluded that it takes at least 12 weeks for the dietary intervention to yeild any fruitful effect on patients with chronic liver diseases, and that continuity and perseverence on the part of both patients and therapists is a necessary pre-condition for the effectiveness to be experienced and observed.
