BACKGROUND: Screening over many years is required to optimize reductions in colorectal cancer (CRC) mortality. However, no prior trials have compared strategies for obtaining long-term adherence.
METHODS: Systems of Support to Increase Colorectal Cancer Screening and Follow-Up was implemented in an integrated health care organization in Washington State. Between 2008 and 2009, 4675 individuals aged 50 to 74 years were randomized to receive the usual care (UC), which included clinic-based strategies to increase CRC screening (arm 1), or, in years 1 and 2, mailings with a call-in number for colonoscopy and mailed fecal tests (arm 2), mailings plus brief telephone assistance (arm 3), or mailings and assistance plus nurse navigation (arm 4). Active-intervention subjects (those in arms 2, 3, and 4 combined) who were still eligible for CRC screening were randomized to mailings being stopped or continued in years 3 and 5. The time in compliance with CRC screening over 5 years was compared for persons assigned to any intervention and persons assigned to UC. Screening tests contributed time on the basis of national guidelines for screening intervals (fecal tests annually, sigmoidoscopy every 5 years, and colonoscopy every 10 years).
RESULTS: All participants contributed data, but they were censored at disenrollment, death, the age of 76 years, or a diagnosis of CRC. Compared with UC participants, intervention participants had 31% more adjusted covered time over 5 years (incidence rate ratio, 1.31; 95% confidence interval, 1.25-1.37; covered time, 47.5% vs 62.1%). Fecal testing accounted for almost all additional covered time.
CONCLUSIONS: In a health care organization with clinic-based activities to increase CRC screening, a centralized program led to increased CRC screening adherence over 5 years. Longer term data on screening adherence and its impact on CRC outcomes are needed. Cancer 2017;123:4472-80. © 2017 American Cancer Society.

BACKGROUND: Clinical practice guidelines (CPGs) recommend universal prenatal screening for Group B Streptococcus (GBS) to identify candidates for intrapartum antibiotic prophylaxis to prevent early onset neonatal GBS infection. Interventions to promote physician adherence to these guidelines are imperative. This study examined the effectiveness of academic detailing (AD) of obstetricians, compared with CPG mailshot and no intervention, on the screening of pregnant women for GBS.
METHODS: A randomized controlled clinical trial was conducted in the medical cooperative of Porto Alegre, Brazil. All obstetricians who assisted in a delivery covered by private health insurance managed by the cooperative in the 3 months preceding the study (n = 241) were invited to participate. The obstetricians were randomized to three groups: direct mail (DM, n = 76), AD (n = 76) and control (C, n = 89, no intervention). Those in the DM group were sent guidelines on GBS. The AD group received the guidelines and an educational visit detailing the guidelines, which was conducted by a trained physician. Data on obstetrician age, gender, time since graduation, whether patients received GBS screening during pregnancy, and obstetricians who requested screening were collected for all participant obstetricians for 3 months before and after the intervention, using database from the private health insurance information system.
RESULTS: Three months post-intervention, the data showed that the proportion of pregnant women screened for GBS was higher in the AD group (25.4%) than in the DM (15.9%) and C (17.7%) groups (P = 0.023). Similar results emerged when the three groups were taken as a cluster (pregnant women and their obstetricians), but the difference was not statistically significant (Poisson regression, P = 0.108). Additionally, when vaginal deliveries were analyzed separately, the proportion screened was higher in the AD group (75%) than in the DM group (41.9%) and the C group (30.4%) (chi-square, P < 0.001).
CONCLUSIONS: The results suggest that AD increased the prevalence of GBS screening in pregnant women in this population.

BACKGROUND: Research resources should address the issues that are most important to people affected by a particular healthcare problem. Systematic identification of stroke survivor, caregiver, and health professional priorities would ensure that scarce research resources are directed to areas that matter most to people affected by stroke.
OBJECTIVE: We aimed to identify the top 10 research priorities relating to life after stroke, as agreed by stroke survivors, caregivers, and health professionals.
METHODS: Key stages involved establishing a priority setting partnership; gathering treatment uncertainties from stroke survivors, caregivers, and health professionals relating to life after stroke (using surveys administered by e-mail, post, and at face-to-face meetings); checking submitted treatment uncertainties to ensure that they were clear, unanswered questions about the effects of a treatment/intervention; interim prioritization to identify the highest priority questions (objectively identified from ranking of personal priorities by original survey respondents); and a final consensus meeting to reach agreement on the top 10 research priorities.
RESULTS: We gathered 548 research questions that were refined into 226 unique unanswered treatment uncertainties. Ninety-seven respondents completed the interim prioritization process, objectively identifying 24 shared priority treatment uncertainties. A representative group of 28 stroke survivors, caregivers, and health professionals attended a final meeting, reaching consensus on the top 10 research priorities relating to life after stroke. Six of the agreed top 10 research priorities related to specific stroke-related impairments, including cognition, aphasia, vision, upper limb, mobility, and fatigue. Three related to more social aspects of \'living with stroke\' including coming to terms with long-term consequences, confidence, and helping stroke survivors and their families \'cope\' with speech problems. One related to the secondary consequences of stroke and subsequent stroke prevention.
CONCLUSIONS: The top 10 research priorities relating to life after stroke have been identified using a rigorous and person-centered approach. These should be used to inform the prioritization and funding of future research relating to life after stroke.

BACKGROUND: Implementation of new guidelines into clinical practice is often incomplete. Direct mail is a simple way of providing information to physicians and may improve implementation of new guidelines on basic life support (BLS). The aim of this study was to describe knowledge of the most recent European Resuscitation Council (ERC) Guidelines for BLS among general practitioners (GPs) and investigate whether direct mail improves theoretical knowledge of these guidelines.
METHODS: All general practice clinics (n=351) in Central Denmark Region were randomised to receive either direct mail (intervention) or no direct mail (control). The direct mail consisted of the official ERC BLS/AED poster and a cover letter outlining changes in compression depth and frequency in the new guidelines. In general practice clinics randomised to intervention, every GP received a direct mail addressed personally to him/her. Two weeks later, a multiple-choice questionnaire on demographics and BLS guidelines were mailed to GPs in both groups.
RESULTS: In total, 830 GPs were included in this study (direct mail, n=408; control, n=422). The response rate was 58%. The majority (91%) of GPs receiving direct mail were familiar with BLS Guidelines 2010 compared to 72% in the control group (P<0.001). Direct mail improved knowledge of the new recommended chest compression depth (67% vs. 40%, P<0.001) and chest compression frequency (62% vs. 40%, P<0.001).
CONCLUSIONS: Direct mail improved knowledge of changes in BLS guidelines and thus facilitated the implementation of this knowledge into clinical practice. Resuscitation councils and medical societies may consider using direct mail as a simple strategy to facilitate implementation of changes in clinical guidelines.

BACKGROUND: The availability of competitive foods in schools is a modifiable factor in efforts to prevent childhood obesity. The Alliance for a Healthier Generation launched the Healthy Schools Program in 2006 to encourage schools to create healthier food environments, including the adoption of nutritional guidelines for competitive beverages and foods. This study examines nationwide awareness and implementation of the guidelines in US public elementary schools.
METHODS: Data were collected from a nationally representative sample of elementary schools using mail-back surveys in 2006-2007, 2007-2008, 2008-2009, and 2009-2010.
RESULTS: From 2006-2007 to 2009-2010, awareness of the Alliance\'s beverage guidelines increased from 35.0% to 51.8% among school administrators (p < .01); awareness of the food guidelines increased from 29.4% to 40.2% (p < .01). By 2009-2010, almost one third of the schools that sold competitive beverages and foods reported having implemented or being in the process of implementing the guidelines. Implementation was higher among schools from Southern states. Schools with a majority of Black or Latino students were less likely to implement the guidelines.
CONCLUSIONS: Awareness and implementation of the Alliance\'s beverage and food guidelines has significantly increased since the 2006-2007 school year, indicating successful diffusion of the guidelines. However, many administrators at schools who sold competitive products were not aware of the guidelines, indicating a need for continued efforts. In addition, lower implementation among schools serving minority students suggests that the Alliance\'s targeted efforts to provide intensive technical assistance to such schools is warranted and necessary.

In 2001, letters filled with a powder containing anthrax (Bacillus anthracis) spores were delivered by mail to a number of governmental and media locations within the United States. In response, the U.S. Centers for Disease Control and Prevention (CDC) provided guidelines for office personnel who might encounter a letter containing suspicious powder. These guidelines were developed during the crisis and in the absence of experimental data from laboratory or field investigations. An obvious need thus exists for quantitative and scientific verification for validation of these guidelines. This study attempts to address this need, adapting earlier work that used a multiple small office test site to create a model system in an open office test site in a vacated office building in which Bacillus atrophaeus spores (as a simulant for B. anthracis spores) were released by opening a letter. Using SF(6) as a tracer gas, smoke tubes (containing stannic chloride) to visualize airflow, culturable aerosol sampling, and aerosol spectrometry we were able to characterize airflow and unmitigated spore aerosol dissemination within the office test site. Subsequently, two scripted test scenarios were used to reproduce selected portions of the existing CDC response guidelines and a modified version where the contaminated letter opener warned co-workers to evacuate then waited 5 min before doing so himself. By not leaving together with other co-workers, the risk of the letter opener cross-contaminating others was eliminated. The total potential spore aerosol exposure of the letter opener was not affected by remaining still and waiting 5 min to allow co-workers to escape first before leaving the office. Closing office doors and quickly deactivating the heating, ventilation, and air conditioning system significantly reduced spore aerosol concentrations outside the main open office in which they had been released.

A good questionnaire design for a clinical trial will minimise bias and maximise precision in the estimates of treatment effect within budget. Attempts to collect more data than will be analysed may risk reducing recruitment (reducing power) and increasing losses to follow-up (possibly introducing bias). The mode of administration can also impact on the cost, quality and completeness of data collected. There is good evidence for design features that improve data completeness but further research is required to evaluate strategies in clinical trials. Theory-based guidelines for style, appearance, and layout of self-administered questionnaires have been proposed but require evaluation.

Compliance with physical activity (PA) recommendations was assessed using objective PA monitoring of ambulatory activity, in two healthy groups of individuals with active and sedentary occupations. The study showed generally low compliance with the guidelines (53% with 10,000 steps a day; 10% with 30 min of moderate activity a day; and 1% with 30 min of moderate activity a day in bouts of at least 10 min (ACSM)). Adherence to guidelines decreased as more rigorous conditions were applied to the PA data. Use of an objective monitor revealed that health enhancing bouts of activity were performed in periods of approximately 1-min duration, which may be due to unavoidable environmental interruptions. These bouts of activity are much shorter than those advocated in the ACSM guidelines, raising questions regarding how actual behaviour, based on objective monitoring, can be reconciled with guidelines based on self-reported PA.

OBJECTIVE: To evaluate the influence of two different modes for delivering guidelines on school teachers\' knowledge on emergency treatment for dental injuries.
METHODS: Cross sectional questionnaire study.
METHODS: Primary schools in Dar es Salaam city council in Tanzania.
METHODS: Primary school teachers.
METHODS: Provision of guidelines by mail or through seminar or no guidelines (control).
METHODS: Knowledge on emergency management of dental injuries
RESULTS: The teachers did not have adequate knowledge on the emergency management of traumatised teeth. Significant differences were observed between the study groups. Teachers from the seminar group were likely to re-implant an avulsed tooth (five times more likely than the control group) or otherwise would transport it in the recommended medium. No significant differences were observed between the groups on their willingness to take the avulsed tooth to a doctor or dentist or on the method or liquid they would use to clean a dirty avulsed tooth.
CONCLUSIONS: Compared to provision of information through mailed guidelines, seminar discussions better improved the school teachers\' knowledge regarding emergency treatment for dental injuries.

The BTS/SIGN British Guideline on the Management of Asthma was published in February 2003 (4). If health outcomes are to be influenced successfully, dissemination of the guideline and implementation of recommendations is essential. We report the dissemination activities undertaken during the 18 weeks following the guideline launch. To facilitate implementation a range of educational materials were produced reflecting the key messages from the guideline. In addition to postal mailing of the guideline to appropriate healthcare professionals, both educational materials and the guidelines were made freely available from the BTS and SIGN websites. In total, 135,710 copies of the guideline and 90,198 copies of the Quick Reference Guide were downloaded in the first 18 weeks, representing a considerable increase over the number of copies of the 1997 guidelines disseminated by mailing alone. Large quantities of educational materials were downloaded with many used for teaching purposes. An on-line survey suggested that most respondents rated the materials as useful or very useful. Using websites to disseminate guidelines is a cost-effective method of informing health professionals of their content and is a more active process than the passive receipt of mailed copies. The availability of interactive educational materials for use in teaching appears to have been popular.
