Diabetic patients who don't control their disease well often develop complications. Their quality of life can then be substantially affected. Lacking social support a vagrant who develops such complications will find it particularly hard to maintain a good quality of life. The application of Parse practice methodology with supplementary social-support theory can help a vagrant diabetic patient to meet his needs and improves his quality of life. The purpose of paper is to provide nurses with a point of reference in relation to the care of such patients.
