Secondary Outcome |
The secondary outcome of this study was the quality of life. It was assessed using the Amharic version of EORTC QLQ-C30 that is found to be reliable and had an acceptable validity to assess the QOL among cancer patients. The questionnaires have 30 items with three scales and 15 different domains. The three scales used were functional, symptom scale, and general health status as a separate scale. Domains such as physical, role, cognitive, emotional, and social functioning under functional scale whereas dyspnea, pain, fatigue, insomnia, appetite loss, nausea/vomiting, constipation, diarrhea as well as financial difficulties under symptom scale and general health status as a separate scale.
The scoring was done according to the Quality of life questionnaire-C30 manual. According to the manual, the quality of life questionnaire version-3 has 30 item questions to assess the quality of life of cancer patients in general. So after the patients' response was taken carefully using questions ranging from Item 1(I1to Item 30 (Iзȯ), the raw score was calculated and further be used for each scales (Functional, symptom and general health status), then linear transformation were undertaken for each domain under the subsequent scales.
This raw score was further be used for each scale (Functional, symptom, and general health status), then linear transformation was undertaken for each domain under the subsequent scales.
The linear transformation from 0-100 was applied to obtain the score S, the individual score for each domain. The linear transformation was done to use individual scores for the subsequent analysis. The formula written below was used for functional, symptom scale, and general status.
Functional scales: S= 1- (RS-1) *100
