Motor Control-based Group Exercise: Can It be Delivered as Effectively by Lay Leaders?

PURPOSE: On the Move (OTM), a motor control-based group exercise program for community-dwelling older adults, has produced greater gains in mobility than a standard group exercise program when delivered by research leaders. The purposes of this study were:1) to examine the effectiveness of OTM versus a standard program when delivered by lay leaders and 2) to compare the outcomes of OTM when delivered by research versus lay leaders. METHODS: Community-dwelling, medically stable older adults who could walk household distances participated. OTM consisted of warm-up, timing and coordination, strengthening, and stretching exercises. The seated standard program consisted of warm-up, aerobic, strengthening and stretching exercises. The primary outcome(s) of function and disability was the Late Life Function and Disability Instrument (LLFDI), and for walking ability were the Six Minute Walk Test and gait speed. RESULTS: 126 participants (mean age = 80.7±7.8 years, gait speed = 0.91 m/s) were randomized to OTM (n=49) or standard (n=77) programs. When taught by lay leaders, there were no significant between-intervention group differences in any of the outcomes (p>0.10). Comparing OTM outcomes between leaders, there was a statistical but not clinically meaningful difference in LLFDI disability (1.87±0.89, p=0.04) when taught by research versus lay leader, and moderate differences (p=0.06) in LLFDI overall function (1.89±1.02) and gait speed (0.05±0.03). Qualitative interview responses suggest that instructor-related concerns may have impacted program outcomes. CONCLUSION: When delivered by lay leaders OTM was not more effective than a standard program for improving function, disability, and mobility in older adults. Health promotion programs designed to improve mobility in community-dwelling older adults and based on a motor control theoretical background, may be best taught by rehabilitation professionals.

Do beliefs of inner-city parents about disease and vaccine risks affect immunization?

OBJECTIVE: The objective of this study was to understand how low income, inner-city parents of preschool children think about childhood diseases and prevention and the impact that this has on late receipt of vaccines. METHODS: Parents of all children born between January 1, 1991, and May 31, 1995, whose child received medical assistance and health care at one of four inner-city, primary care clinics in Pittsburgh, PA, completed a telephone interview and gave consent for a vaccine record review. The main outcome measures were lateness for first and third diphtheria and tetanus toxoids and pertussis vaccines (DTP) and not receiving at least four DTP, three polio virus containing and one measles, mumps and rubella (MMR) doses by 19 months. RESULTS: A total of 483 parents participated. Fifteen percent of children were late for the first DTP, 52% for the third DTP, and 40% had not received at least four DTP, three polio and one MMR by 19 months of age. Statistically significant factors associated with lateness at 19 months included: having three or more children, having two children, beliefs regarding the severity of immunization side effects, and being African American. CONCLUSIONS: The results of this study indicate that a combination of life circumstances, as well as cognitive factors were associated with late immunization.

The role of qualitative methods for investigating barriers to adult immunization.

In 1999, the Agency for Healthcare Research and Quality funded a study of barriers to immunization, which included a short-term qualitative data collection to assess the organizational and cultural features of selected primary care practices and to explore their impact on adult immunization rates. The authors describe the short-term qualitative data collection system and the contributions made by the qualitative study to the parent project. They address previously held concerns about qualitative research and provide a system that can be replicated or modified for use for projects designed to assess complex attitudes and behaviors that affect health outcomes.

Tailoring interventions: understanding medical practice culture.

This article describes the results of a study that used intensive direct observations of eight medical practices to assess the factors affecting the barriers and facilitators to adult immunization for influenza and pneumonia. The study aimed to describe the culture of these practices by identifying key features that facilitate or deter the immunization process. The article presents profiles of six of the eight practices describing their cultural and organizational frameworks. Six features that are critical to an understanding of the cultures of these practices, particularly as they relate to receptivity to influenza immunization for diverse practices and patient populations, are highlighted. These include policies and procedures, funding source, physician philosophy, patient receptivity to provider recommendation, and physical environment and social environment. The article also discusses strategies for applying knowledge about the culture of each practice to introduce appropriate and feasible interventions aimed at increasing immunization rates.
