Factors Affecting Interdialytic Weight Gain (IDWG) in Hemodialysis Patients with Precede-Proceed Theory Approach

Patients with End Stage Renal Disease (ESRD) who receive hemodialysis often failed to undergo treatment of diet and fluids are recommended. This condition can cause Interdialytic Weight Gain (IDWG) increases. Increased IDWG is also found in hemodialysis patients in Hemodialysis Unit RSU Haji Surabaya. Higher IDWG is strongly associated with mortality and can reduce the effectiveness of the treatment and cause unpredictable disease progression and a high likelihood of complications, but factors related to IDWG in hemodialysis patients in RSU Haji Surabaya still inexplicable. It is important to know the factor related to IDWG in order to make an appropriate intervention to the patients. This study aimed to analyze factors affecting interdialytic weight gain in hemodialysis patients RSU Haji Surabaya. Cross sectional study design involved 79 total sampling respondents. Independent variables were fluid intake, thirst, self efficacy, and stress. Dependent variable was interdialytic weight gain. Data were obtained using questionnaire then analyzed with Spearman rho with degree of significant p ≤ 0.05. IDWG increase in hemodialysis patients was significantly associated with fluid intake (p = 0.006; r = 0.304), thirst (p = 0.001; r = 0.382), and self efficacy (p = 0.035; r = -0.237). The increasing of IDWG can be avoid by controlling fluid intake, thirst management, and improving patient self efficacy. Nurse hemodialysis is expected to make an appropriate strategy management so that IDWG increase can be controlled. Further research suggested to examine the intervention or nursing model that may suppress IDWG increase in hemodialysis patients.
