Abstract: Objective:To investigate the improving effects of the continuous nursing based on Omaha system on self-care ability in patients with intestinal obstruction caused by peritoneal dialysis peritonitis.Methods:Sixty-eight patients with intestinal obstruction caused by peritoneal dialysis peritonitis were randomly divided into the control group and observation group(34 cases each group).The control group and observation group were nursed with routine care and continuous nursing based on Omaha system,respectively.The disease knowledge,and scores of exercise of self-care agency scale(ESCA),health promoting lifestyle profile(HPLP) and short form 36 health survey questionnaire(SF-36) between two groups were compared.Results:At discharge,the differences of the disease knowledge,and scores of ESCA,HPLP and SF-36 between two groups were not statistically significant(P>0.05).After 3 months of discharge,the indicators of patients were significantly higher than those at discharge(P<0.05 to P<0.01),and the indicators in observation group were significantly higher than those in control group(P<0.05 to P<0.01).Conclusions:The continuous nursing based on Omaha system can significantly improve the disease knowledge and self-care ability,behavioral health and life quality of patients with intestinal obstruction caused by peritoneal dialysis peritonitis.
