Abstract: ［Abstract］Objective To investigate the role of the extended-care in improving the compliance with low-salt diet in elderly patients with hypertension. Methods We selected 100 cases of elderly patients with hypertension in hospital.The 100 cases were divided into control group（50 cases）and observation group（50 cases） randomly.Observation group was given comprehensive intervention in low-salt diet education and control group was given traditional low-salt diet education.Tow groups were divided into three stages （on the day of admission，seven days after admission， one month after discharge）.We analyzed low-salt cognitive scores，low-salt behavioral scores and salt-intake/d comparably．Results　On the day of admission，tow groups had no statistically significant difference（P＞0.05）in low-salt cognitive scores，low-salt behavioral scores and salt-intake/d；seven days after admission，tow groups had statistically significant difforence（P＜0.05）in low-salt cognitive scores，low-salt behavioral scores and salt-intake/d；one month after discharge，tow groups had statistically significant difference（P＜0.05）in low-salt cognitive scores，low-salt behavioral scores and salt-intake/d . Conclusion We use comprehensive intervention method to elderly patients with hypertension in low-salt diet education，through personalized low-salt diet education following evidence-based nursing，we can increase the compliance with low-salt diet in elderly patients with hypertension after discharge and improve blood pressure control effectively and to promote the image of the hospital and achieve the higher satisfaction from patients and families.
