Rapidly declining of kidney function among patients with chronic kidney disease is a major problem of the health system. Perception of health conditions affects the delay of disease progression. The objective of this descriptive research was to study illness representation among patients with chronic kidney disease stage 3 with a rapid decline of kidney function. One hundred and five patients with chronic kidney disease stage 3 at Srinagarind hospital were assessed with Chronic Kidney Disease Stage3 Perception Questionnaire (CKD-3PQ) during April and June 2019. This instrument was used for data collection. It was developed based on The Commonsense Model consisted of 6 aspects: 1.Identity 2. Causes 3. Timeline 4. Control / Cure 5. Consequences 6. Emotional. Content validity was evaluated by five experts in the field and quantified as content validity index (CVI). It is 0.97. The Cronbach’s alpha coefficient was used to determine the internal consistency. It was 0.89. Descriptive statistics were used to analyze the data: frequency percentage mean and standard deviation.
The results of the study showed that illness representations among patients with chronic kidney disease stage 3 with a rapid decline of kidney function were as follows: 1. Identity: Identity of CKD stage 3 with rapidly decline among participants was at moderate level (Mean = 2.95, the SD = .43). They had two distinctive identities 1. Various symptoms 2. No abnormal symptoms.2. Causes: Causes that perceived by participants were 3 majors causes as follow: 1. Salty food consumption (Mean=4.76, SD=.56) 2. Pickled fish consumption (Mean=4.65, SD=.66) 3. Eat out and delicatessen (Mean=4.59, SD=.64)3. Timeline: Timeline of CKD stage3 with rapidly decline among participants was at moderate level (Mean= 3.66, SD =.73). CKD timeline characteristics from this study were mixed types consisted of acute chronic and cyclical characteristic.4. Consequence: Consequence that perceived of CKD stage3 with rapidly decline at a moderate level (Mean = 2.39 SD = .66). Participants perceived that chronic kidney disease did not affect much on many dimensions of life.5. Control/Cure: Participants perceived that CKD stage3 with rapidly declining can control and cure at a high level (Mean = 4.56 SD = .42) and moreover also they perceived that herbs able to treat chronic stage 3 kidney disease at a high level (Mean = 4.2, SD = .82)6. Emotional: Participants perceived that CKD stage 3 with rapidly declining influenced emotional problem at a moderate level (Mean = 2.97, SD = 1.04)
These results suggests that patients with chronic kidney disease stage 3 with rapidly declining have both medical and personal perceptions. Therefore, assessing the perceptions of illness in patients with chronic kidney disease stage 3 is important and may affect self-care and disease progression.
