Triangulating Clinically Meaningful Change in the Six-minute Walk Test in Individuals with Chronic Heart Failure: A Systematic Review

Purpose

The purpose of the present review was to use existing, published data to provide an estimate of the amount of change in six-minute walk test distance (Δ6MWT) that represents a clinically meaningful change in individuals with chronic heart failure (CHF).

Methods

The present review included two separate literature searches of the CINAHL and Medline databases for articles that: (1) reported the intraclass correlation coefficient (ICC) of the 6MWT in individuals with CHF, and (2) used the 6MWT along with either aerobic capacity or health-related quality of life (HRQL) as study endpoints in randomized controlled trials (RCTs) of exercise-based intervention for individuals with CHF. The ICCs were used to calculate the minimum detectable difference (MDD) at the 95% confidence interval for each included study. The Δ6MWT associated with aerobic capacity and HRQL within-group effect sizes for the intervention and control groups in each included RCT was analyzed using receiver operating characteristic (ROC) curves.

Results

Thirteen articles reported the ICC for the 6MWT. The mean (standard deviation) MDD calculated based on these data was 43.1(16.8) m. Eighteen RCTs measured the 6MWT and either aerobic capacity and/or HRQL. A Δ6MWT of 40–45 m was associated with at least moderate aerobic capacity and HRQL effect sizes in the intervention groups. The Δ6MWT thresholds that discriminated between intervention and control groups using ROC curves revealed the following sensitivity/specificity for the respective thresholds: 19 m, 94.4/83.3%, 32 m, 83.3/94.4%, and 48 m 44.4/100% (AUC = .935, p = .009, CI_95% .855, 1.015).

Conclusions

A Δ6MWT of approximately 45 m appears to exceed measurement error and be associated with significant changes in either aerobic capacity and/or HRQL.Key Words: heart failure, six-minute walk test, clinically meaningful change, minimum detectable difference     

Doulas as community health workers: lessons learned from a volunteer program

Doulas, women who primarily provide social support during childbirth, have been associated with a number of positive health outcomes. Because the primary model of practice for doulas is a fee-for-service model in which families privately hire a doula, many expectant women who could benefit from doula support are unable to access the service. The Doulas Care program, located in Ann Arbor, Michigan, represents one model in which doulas provide services without charge. As a result of their extended role in the community, doulas who work with the Doulas Care program have unique educational needs. Through the use of focus groups with the program's volunteer doulas, educational needs related to overcoming barriers to being a doula working in the community were identified. Recommendations for education and training are made to improve the support doulas offer as community health outreach workers.     

UCLA COMMUNITY COLLEGE BIBLIOGRAPHY

The research reported in this article explored the extent of self‐censorship in community college theatre programs across the country. What part of the college administration plays in such censorship is also examined. Censorship does exist in community college theatre. Much of the censorship is self‐imposed. Directors avoid plays that are controversial. The audience is protected from harm. Profanity, racial slurs, and negative religious references are cut. When cuts are not made, disclaimers are often published in programs or placed in the lobby or both. Further research opportunities suggested by this study lie in examinations of how theatre departments deal with copyright issues when cutting objectionable material from plays. Defining the responsibility of the community college theatre program to the community is another area of research that needs to be addressed. Little censorship occurs from external sources. Finally, how the responsibilities of the college and the theatre to truth can be resolved with the presence of censorship in academic theatre is an area yet to be adequately explored.     

Academic Outcomes Among a Sample of Learning Support Community College Students

This research examined the relationship between placement in a learning support college program and subsequent academic outcomes. The sample consisted of 275 entering freshmen students who were enrolled in the Learning Support reading courses in the fall of 2005. Data were collected from the Gordon College Office of Institutional Research. The data showed that of the 275 students who enrolled in a Learning Support reading course in the fall 2005 semester, 189 returned for the spring 2006 semester. Data also showed that 58% of the 275 students enrolled in Learning Support reading during fall 2005 successfully completed a basic reading intensive course upon completion of their remedial reading class. One hundred eighty seven students who had previously completed Learning Support reading enrolled (spring 2006 or later) in Introductory English 101 and 121 passed. Fifty-five students who had completed Learning Support reading enrolled (spring 2006 or later) in History 1121, Western Civilization, and 20 students passed. Six of the 205 students who completed Learning Support reading graduated Gordon College within a three-year period. The results of the present study indicate that the Learning Support Reading Program in place at Gordon College has proven to be a beneficial tool for at-risk college students. It is assumed that programs such as the Learning Support Program described here may help students build a foundation that will aid them throughout their college career.
