This study is designed to examine the effects of environment and structure of the Community Clinical Oncology Program (CCOP) on performance as measured by patient accrual to National Cancer Institute (NCI)-approved treatment protocols.
DATA SOURCES/STUDY SETTING: Data and analysis are part of a larger evaluation of the NCI Community Clinical Oncology Program during its second funding cycle, June 1987-May 1990. Data, taken from primary and secondary sources, included a survey of selected informants in CCOPs and research bases, CCOP grant applications, CCOP annual progress reports, and site visits to a subsample of CCOPs (N = 20) and research bases (N = 5). Accrual data were obtained from NCI records.
Analysis involved three complementary sets of factors: the local health care resources environment available to the CCOP, the larger policy environment as reflected by the relationship of the CCOP to selected research bases and the NCI, and the operational structure of the CCOP itself. A hierarchical model examined the separate and cumulative effects of local and policy environment and structure on performance.
Other things equal, the primary predictors of treatment accrual were: (1) the larger policy environment, as measured by the attendance of nurses at research base meetings; and (2) operational structure, as measured by the number and character of components within participating CCOPs and the number of hours per week worked by data managers. These factors explained 73 percent of the total variance in accrual performance.
Findings suggest criteria for selecting the types of organizations to participate in the alliance, as well as for establishing guidelines for managing such alliances. A future challenge is to determine the extent to which factors predicting accrual to cancer treatment clinical trials are equally important as predictors of accrual to cancer prevention and control trials.
本研究旨在探讨社区临床肿瘤项目(CCOP)的环境和结构对患者入组美国国立癌症研究所(NCI)批准的治疗方案的表现的影响。
数据来源/研究背景:数据和分析是对NCI社区临床肿瘤项目在其第二个资助周期(1987年6月至1990年5月)进行的更大规模评估的一部分。数据来自主要和次要来源,包括对CCOP和研究基地中选定信息提供者的调查、CCOP资助申请、CCOP年度进展报告,以及对一部分CCOP(N = 20)和研究基地(N = 5)的实地考察。入组数据从NCI记录中获取。
分析涉及三组互补的因素:CCOP可利用的当地医疗保健资源环境、CCOP与选定研究基地及NCI的关系所反映的更大政策环境,以及CCOP自身的运营结构。一个层次模型检验了当地和政策环境及结构对表现的单独和累积影响。
在其他条件相同的情况下,治疗入组的主要预测因素为:(1)更大的政策环境,以护士参加研究基地会议的情况衡量;(2)运营结构,以参与的CCOP内组成部分的数量和性质以及数据管理人员每周工作小时数衡量。这些因素解释了入组表现总方差的73%。
研究结果为选择参与联盟的组织类型提供了标准,也为管理此类联盟制定了指导方针。未来的一个挑战是确定预测癌症治疗临床试验入组的因素在多大程度上与预测癌症预防和控制试验入组的因素同样重要。
