Step Ahead A Worksite Obesity Prevention Trial Among Hospital Employees

BACKGROUND The worksite represents a promising venue in which to address the issue of obesity. DESIGN Pair-matched, cluster-RCT. Data were collected from 2005 to 2008 and analyzed in 2008. SETTING/PARTICIPANTS A random sample of 806 employees was selected to represent the workforce of six hospitals in central Massachusetts. INTERVENTION The 2-year ecologic intervention sought to prevent weight gain through changes in worksite weight-related norms using strategies targeted at the organization, interpersonal environment, and employees. MAIN OUTCOME MEASURES The primary outcome was change in BMI at the 12- and 24-month follow-ups. Change in perceptions of organizational commitment to employee health and normative coworker behaviors were secondary outcomes. RESULTS There was no impact of the intervention on change in BMI from baseline to 12 (beta=0.272; 95% CI=-0.271, 0.782) or 24 months (beta=0.276; 95% CI=-0.338, 0.890) in intention-to-treat analysis. When intervention exposure (scale=0 to 100) was used as the independent variable, there was a decrease of 0.012 BMI units (95% CI=-0.025, 0.001) for each unit increase in intervention participation at the 24-month follow-up. Employees in intervention sites reported significantly greater improvements in perceptions of organizational commitment to employee health at 12 and 24 months compared to control sites, but there was no impact on perceptions of normative coworker behaviors. CONCLUSIONS The intervention had a dose-response relationship with BMI, with positive effects proportional to extent of participation. Although the intervention was able to change organizational perceptions, successfully improving changes in actual and perceived social norms may be needed to achieve population-level impact in complex worksite organizations.

Screening for Colorectal Cancer on the Front Line

OBJECTIVE:The aim of this study was to assess knowledge, beliefs, and practices of primary care clinicians regarding colorectal cancer screening.METHODS:We surveyed 77 primary care providers in six clinics in central Massachusetts to evaluate several factors related to colorectal cancer screening.RESULTS:Most agreed with guidelines for fecal occult blood test (97%) and sigmoidoscopy (87%), which were reported commonly as usual practice. Although the majority (86%) recommended colonoscopy as a colorectal cancer screening test, it was infrequently reported as usual practice. Also, 36% considered barium enema a colorectal cancer screening option, and it was rarely reported as usual practice. Despite lack of evidence supporting effectiveness, digital rectal examinations and in-office fecal occult blood test were commonly reported as usual practice. However, these were usually reported in combination with a guideline-endorsed testing option. Although only 10% reported that fecal occult blood test/home was frequently refused, 60% reported sigmoidoscopy was. Frequently cited patient barriers to sigmoidoscopy compliance included fear the procedure would hurt and that patients assume symptoms occur if there is a problem. Perceptions of health systems barriers to sigmoidoscopy were less strong.CONCLUSIONS:Most providers recommended guideline-endorsed colorectal cancer screening. However, patient refusal for sigmoidoscopy was common. Results indicate that multiple levels of intervention, including patient and provider education and systems strategies, may help increase prevalence.

Perceptions of Worksite Support and Employee Obesity, Activity and Diet

OBJECTIVES To examine the associations of perceptions of organizational commitment to employee health and coworker physical activity and eating behaviors with body mass index (BMI), physical activity, and eating behaviors in hospital employees. METHODS Baseline data from 899 employees participating in a worksite weight-gain prevention trial were analyzed. RESULTS Greater perception of organizational commitment to employee health was associated with lower BMI. Greater perceptions of coworker healthy eating and physical activity behaviors were associated with fruit and vegetable and saturated fat consumption and physical activity, respectively. CONCLUSIONS Improving organizational commitment and facilitating supportive interpersonal environments could improve obesity control among working populations.

Evaluating the Implementation of a Hospital Work-Site Obesity Prevention Intervention: Applying the RE-AIM Framework

Step Ahead was a randomized controlled trial testing ecologically based weight gain prevention interventions in the hospital workplace. The RE-AIM framework is used to assess the intervention’s Reach, Effectiveness, Adoption, Implementation, and Maintenance. Some intervention components reached a large percentage of the workforce. Although the intervention was not effective in changing BMI on a population level, a dose response was observed, in which persons who used more of the intervention components and materials were more likely to prevent weight gain. Adoption of the intervention by sites invited was 100%. Implementation of healthy eating interventions in the hospital setting was especially challenging because close collaboration was necessary with hospital employees and contractors, and their mission and priorities often were at odds with the intervention goals. There are some notable instances of intervention maintenance at the institutional level: Farmers markets have been expanded at both sites since the end of the intervention period, and new wellness programs are being adopted and implemented. Implications for practice include the translation of this research into other workplace settings.

Keeping a Step Ahead: formative phase of a workplace intervention trial to prevent obesity

Objective: Ecological interventions hold promise for promoting overweight and obesity prevention in worksites. Given the paucity of evaluative research in the hospital worksite setting, considerable formative work is required for successful implementation and evaluation. This paper describes the formative phases of Step Ahead, a site‐randomized controlled trial of a multilevel intervention that promotes physical activity and healthy eating in six hospitals in central Massachusetts. The purpose of the formative research phase was to increase the feasibility, effectiveness, and likelihood of sustainability of the intervention.

Missed Opportunities To Impact Fast Response to AMI Symptoms.

The potential for reducing cardiovascular disease mortality rates lies both in prevention and treatment. The earlier treatment is administered, the greater the benefit. Thus, duration of time from onset of symptoms of acute myocardial infarction to administration of treatment is important. One major factor contributing to failure to receive efficacious therapy is the delay time from acute myocardial infarction (AMI) symptom onset to hospital arrival. This paper examines the relationship of several factors with regard to intentions to seek care promptly for symptoms of AMI. A random-digit dialed telephone survey (n = 1294) was conducted in 20 communities located in 10 states. People who said they would wait until they were very sure that symptoms were a heart attack were older, reported their insurance did not pay for ambulance services, and reported less confidence in knowing signs and symptoms in themselves. When acknowledging symptoms of a heart attack, African-Americans and people with more than a high school education reported intention to act quickly. No measures of personal health history, nor interaction with primary care physicians or cardiologists were significantly related to intention to act fast. The study confirms the importance of attribution and perceived self-confidence in symptom recognition in care seeking. The lack of significant role of health history (i.e. those with chronic conditions or risk factors) and clinician contact highlights missed opportunities for health care providers to educate and encourage patients about their risk and appropriate action.

Health Care Providers’ Perspectives on Patient Delay for Seeking Care for Symptoms of Acute Myocardial Infarction

To inform intervention development in a multisite randomized community trial, the Rapid Early Action for Coronary Treatment (REACT) project formative research was undertaken for the purpose of investigating the knowledge, beliefs, perceptions, and usual practice of health care professionals. A total of 24 key informant interviews of cardiologists and emergency physicians and 15 focus groups (91 participants) were conducted in five major geographic regions: Northeast, Northwest, Southeast, Southwest, and Midwest. Transcript analyses revealed that clinicians are somewhat unaware of the empirical evidence related to the problem of patient delay, are concerned about the practice constraints they face, and would benefit from concrete suggestions about how to improve patient education and encourage fast action. Findings provide guidance for selection of educational strategies and messages for health providers as well as patients and the public.

Weight gain prevention in the school worksite setting: results of a multi-level cluster randomized trial.

OBJECTIVE To describe the effectiveness, reach and implementation of a weight gain prevention intervention among public school employees. METHOD A multi-level intervention was tested in a cluster randomized trial among 782 employees in 12 central Massachusetts public high schools from 2009 to 2012. The intervention targeted the nutrition and physical activity environment and policies, the social environment and individual knowledge, attitudes and skills. The intervention was compared to a materials only condition. The primary outcome measures were change in weight and body mass index (BMI) at 24-month follow-up. Implementation of physical environment, policy and social environment strategies at the school and interpersonal levels, and intervention participation at the individual level were assessed. RESULTS At 24-month follow-up, there was a net change (difference of the difference) of -3.03 pounds (p=.04) and of -.48 BMI units (p=.05) between intervention and comparison conditions. The majority of intervention strategies were successfully implemented by all intervention schools, although establishing formal policies was challenging. Employee participation in programs targeting the physical and social environment was maintained over time. CONCLUSION This study supports that a multi-level intervention integrated within the organizational culture can be successfully implemented and prevent weight gain in public high school employees.

Formative research methods to understand patient and provider responses to heart attack symptoms

Abstract Formative research is often required for program planning, and for reducing uncertainty about generalizability of program effects. This article describes and justifies methods of formative research conducted for the REACT study (Rapid Early Action for Coronary Treatment), a multi-center collaborative randomized community trial aimed at reducing patient delay in seeking care for acute myocardial infarction (AMI). Formative research cast light on patient and community members’ decision-making process in seeking help for AMI, as well as barriers and facilitators of this process. Investigators at all five REACT Field Centers participated in the formative research. The process consisted of: (1) developing a common theoretical framework for the study intervention; (2) conducting a literature review and qualitative research to identify and address gaps in knowledge; and (3) developing a common protocol for the REACT study that accommodated the diversity of the target communities in terms of services, resources, history, and ethnicity. Analysis employed triangulation, defined as an explicit search for heterogeneous data sources to reduce uncertainty about forces at work and opportunities for intervention across settings and populations. Because the collection and interpretation of data went in stages, staff of several REACT Field Centers had independent input to the overall synthesis, then shared and revised the results. Advantages and limitations of this approach are discussed.

A path analysis of factors associated with distress among first-degree female relatives of women with breast cancer diagnosis

Patterns and predictors of psychological distress in first-degree female relatives (N = 624) of newly diagnosed breast cancer patients were explored. First-degree female relatives who were high monitors reported greater cancer-specific and general distress than did low monitors. Greater optimism was associated with lower cancer-specific distress. Optimisms effect on general distress was moderated by womens level of monitoring. Greater optimism was associated with lower general distress for both high and low monitors, but the effect was stronger for high monitors than for low monitors. Avoidance and engaged coping were associated with higher distress. A close relationship with the cancer patient was related to higher cancer-specific distress but lower general distress. Further understanding of the process of adjustment in these women awaits longitudinal study.
