Secondary and tertiary prevention of chronic illness is a major challenge for the United States healthcare system. Controlled studies show that interventions can enhance secondary prevention in primary care practices, but they shed little light on implementation of secondary prevention outside the experimental context. This study examines the adoption and implementation of an important set of secondary and tertiary prevention efforts--diabetes management strategies--for type 2 diabetes in the everyday clinical practice of primary care. It explores whether adoption and implementation processes differ by type of strategy or prevalence of diabetes among patients in the practice.
Holistic case studies (those used to assess a single analytic unit, in this case, the physician group practice, as opposed to multiple embedded subunits) were conducted in 2001-2002 on six primary care practices in North Carolina identified from a statewide physician survey on strategies for diabetes management. Practices were selected by prevalence of diabetes and type of strategy for diabetes management--patient oriented (focused on self-management) versus biomedical (focused on secondary prevention practices). Results were derived from thematic analysis of interviews and secondary documents.
Adoption and implementation did not differ by diabetes prevalence or type of diabetes strategy. All practices had a routine forum for vetting new strategies, and most used traditional channels for identifying them. Implementation often required adaptation of the strategy and the organization. Sustained use of a diabetes strategy depended on favorable organizational policies and procedures (e.g., training, job redesign) and ongoing commitment of resources.
Diabetes management strategies are often complex and require adoption and implementation processes different from those described by classic innovation diffusion models. Alternative conceptual models that consider organizational process, structure, and culture are needed.
慢性病的二级和三级预防是美国医疗保健系统面临的一项重大挑战。对照研究表明,干预措施可以加强初级保健机构中的二级预防,但对于实验环境之外的二级预防实施情况却鲜有涉及。本研究考察了在初级保健日常临床实践中,针对2型糖尿病的一系列重要的二级和三级预防措施——糖尿病管理策略——的采用和实施情况。它探讨了采用和实施过程是否因策略类型或该机构中糖尿病患者的患病率而异。
2001年至2002年,对北卡罗来纳州的六个初级保健机构进行了整体案例研究(用于评估单个分析单元,在本案例中为医生团体诊所,而非多个嵌入式子单元),这些机构是从全州范围内关于糖尿病管理策略的医生调查中确定的。根据糖尿病患病率和糖尿病管理策略类型——以患者为导向(侧重于自我管理)与生物医学导向(侧重于二级预防实践)——选择了这些机构。结果来自对访谈和辅助文件的主题分析。
采用和实施情况不因糖尿病患病率或糖尿病策略类型而有所不同。所有机构都有一个审查新策略的常规论坛,并且大多数通过传统渠道来识别新策略。实施通常需要对策略和机构进行调整。糖尿病策略的持续使用取决于有利的组织政策和程序(如培训、工作重新设计)以及资源的持续投入。
糖尿病管理策略通常很复杂,其采用和实施过程与经典创新扩散模型所描述的不同。需要考虑组织流程、结构和文化的替代概念模型。
