摘要: 目的 观察循证护理模式下的低盐饮食干预对老年高血压患者院外低盐饮食依从性的影响.方法选取昆明医科大学附属延安医院老病科, 2014年3月至2017年1月收治的640例老年高血压患者, 采取随机数字表法分为对照组 (320例) 与观察组 (320例) .对照组采取传统低盐饮食宣教方法, 观察组采取循证护理模式下的低盐饮食宣教方法, 对2组患者分7个时点 (出院当日、出院后2周、出院后1月、出院后3月、出院后6月、出院后9月、出院后12月) 进行低盐饮食认知行为评分及每日盐摄入量的对比分析.结果 观察组与对照组的低盐饮食认知评分对比, 除出院后2周, 其余6个时点的比较差异均有统计学意义 (P<0.01) ;观察组与对照组的低盐饮食行为评分对比, 7个时点的比较差异均有统计学意义 (P<0.01) ;观察组与对照组的每日盐摄入量的对比, 7个时点的比较差异均有统计学意义 (P<0.01) .结论 通过循证护理模式下的低盐饮食干预, 可以提高院外老年高血压患者的低盐饮食认知行为评分, 降低每日盐摄入量.故循证延伸干预对提升院外老年高血压患者低盐饮食依从性效果显著.Abstract: Objective To observe the effect of evidence-based extension intervention nursing model on low-salt diet compliance in elderly hypertensive patients.Methods We selected 640 cases of elderly hypertensive patients in the department of geriatrics, Yan'an Affiliated Hospital of Kunming Medical University, from March2014 to March 2017.The 640 cases were divided into control group (320 cases) and observation group (320 cases) randomly.Observation group was given evidence-based intervention in low-salt diet education and control group was given traditional low-salt diet education.Two groups were then divided into seven stages (on the day of discharge, two weeks after discharge, one month after discharge, three months after discharge, six months after discharge, nine months after discharge, one year after discharge) .We analyzed low-salt cognitive scores, low-salt behavioral scores and salt-intake/d comparably.Results Except two weeks after discharge, in other six stages of two groups had statistically significant difference (P<0.01) in low-salt cognitive scores; In seven stages, two groups had statistically significance difference (P<0.01) in low-salt behavioral scores;In seven stages, two groups had statistically significance difference (P<0.01) in salt-intake/d.Conclusions Evidence-based extension intervention nursing model can effectively improve the low-salt cognitive and behavioral scores, decrease salt-intake/d, and improve the compliance with low-salt diet of the elderly hypertensive patients after discharge.
