Aims To test if training and support of primary health care providers (PHCP), financial reimbursement to PHCP for screening and brief advice, and option for PHCP to refer screen positive patients to an internet-based method of giving advice (eBI) increases PHCP's delivery of screening and advice to heavy drinkers, compared to a control group of PHCPs.Design Cluster randomized factorial trial with 12-week implementation measurement period.Setting Primary health care units (PHCU) in different locations throughout Catalonia, England, Netherlands, Poland and Sweden.Participants 120 PHCU, 24 in each of Catalonia, England, Netherlands, Poland and Sweden.Interventions PHCUs were randomized to one of eight groups: care as usual, training and support (TS), financial reimbursement (FR), and eBI; paired combinations of TS, FR and eBI, and all of FR, TS and eBI.Outcome measures Primary outcome measures is proportion of eligible patients screened during a 12-week implementation period. Secondary outcome measures are proportion of screen positive patients advised; and, proportion of consulting adult patients given an intervention (screening and advice to screen positives) during the same 12-week implementation period.Results During a 4-week baseline measurement period, 5.9 (95% CI 3.4 to 8.4)per 100 adult patients consulting per PHCU were screened for their alcohol consumption. Based on the factorial design, PHCU that received TS had a 1.48 (95% CI 1.13 to 1.95)relatively higher proportion of patients screened during the 12-week implementation period than PHCU that did not receive TS; PHCU that received FR had a 2.00 (95% CI 1.56 to 2.56) relatively higher proportion than no FR. The option of referral to eBI did not have a higher proportion. A combination of TS plus FR had a 2.34 (95% CI 1.77 to 3.10) relatively higher proportion of patients screened than no TS plus FR. A combination of TS plus FR plus eBI had a 1.68 (95% CI 1.11 to 2.53) relatively higher proportion of patients screened than no TS plus FR plus eBI.Conclusions Training and support of PHCP, and financial reimbursement to PHCP for screening and brief advice increase the proportion of adult patients screened for their alcohol consumption, at least in the short term. Trial registration ClinicalTrials.gov. Trial identifier: NCT015015523
The findings show that the studied factors (role security and therapeutic commitment) are not of great importance for alcohol screening and BI rates. Given the fact that screening and brief intervention implementation rate has not changed much in the last decade in spite of increased policy emphasis, training initiatives and more research being published, this raises a question about what else is needed to enhance implementation.
El concepto de alimento funcional, aún no consensuado científicamente, surge en el seno de la Nutrición Óptima, encaminada a modificar aspectos genéticos y fisiológicos y a la prevención y tratamiento de enfermedades, más allá de la mera cobertura de las necesidades de nutrientes. Bajo la perspectiva de la Unión Europea, pueden ser tanto alimentos naturales como procesados industrialmente. Los alimentos funcionales más relevantes y sobre los que recae la más sólida evidencia científica son los probióticos, microorganismos vivos representados fundamentalmente por los derivados lácteos fermentados. Los prebióticos, como los fructanos tipo inulina, son el sustrato trófico de los probióticos y potenciales selectores de la flora colónica. La asociación de un prebiótico y un probiótico se denomina simbiótico. Se conocen innumerables sustancias con actividad funcional: fibra soluble e insoluble, fitosteroles, fitoestrógenos, ácidos grasos monoinsaturados y poliinsaturados, derivados fenólicos, vitaminas y otros fitoquímicos. Los alimentos funcionales ejercen su actividad en múltiples sistemas, especialmente el gastrointestinal, cardiovascular e inmunológico. Se comportan como potenciadores del desarrollo y la diferenciación, moduladores del metabolismo de nutrientes, la expresión génica, el estrés oxidativo y la esfera psíquica. La construcción de alegaciones sanitarias dirigidas al consumidor debe cimentarse en el conocimiento científico y la regulación legal. Es preciso encontrar biomarcadores eficientes del efecto biológico, analizar las posibles interacciones y realizar estudios válidos en humanos. El objetivo prioritario, sin embargo, debe ser la dieta en su conjunto. Emerge así el futuro reto de una dieta funcional.
IntroductionEarly identification (EI) and brief interventions (BIs) for risky drinkers are effective tools in primary care. Lack of time in daily practice has been identified as one of the main barriers to implementation of BI. There is growing evidence that facilitated access by primary healthcare professionals (PHCPs) to a web-based BI can be a time-saving alternative to standard face-to-face BIs, but there is as yet no evidence about the effectiveness of this approach relative to conventional BI. The main aim of this study is to test non-inferiority of facilitation to a web-based BI for risky drinkers delivered by PHCP against face-to-face BI.Method and analysisA randomised controlled non-inferiority trial comparing both interventions will be performed in primary care health centres in Catalonia, Spain. Unselected adult patients attending participating centres will be given a leaflet inviting them to log on to a website to complete the Alcohol Use Disorders Identification Test (AUDIT-C) alcohol screening questionnaire. Participants with positive results will be requested online to complete a trial module including consent, baseline assessment and randomisation to either face-to-face BI by the practitioner or BI via the alcohol reduction website. Follow-up assessment of risky drinking will be undertaken online at 3 months and 1 year using the full AUDIT and D5-EQD5 scale. Proportions of risky drinkers in each group will be calculated and non-inferiority assessed against a specified margin of 10%. Assuming reduction of 30% of risky drinkers receiving standard intervention, 1000 patients will be required to give 90% power to reject the null hypothesis.Ethics and disseminationThe protocol was approved by the Ethics Commmittee of IDIAP Jordi Gol i Gurina P14/028. The findings of the trial will be disseminated through peer-reviewed journals, national and international conference presentations.Trial registration numberClinicalTrials.gov NCT02082990.
BackgroundBrief interventions in primary healthcare are cost-effective in reducing drinking problems but poorly implemented in routine practice. Although evidence about implementing brief interventions is growing, knowledge is limited with regard to impact of initial role security and therapeutic commitment on brief intervention implementation.MethodsIn a cluster randomised factorial trial, 120 primary healthcare units (PHCUs) were randomised to eight groups: care as usual, training and support, financial reimbursement, and the opportunity to refer patients to an internet-based brief intervention (e-BI); paired combinations of these three strategies, and all three strategies combined. To explore the impact of initial role security and therapeutic commitment on implementing brief interventions, we performed multilevel linear regression analyses adapted to the factorial design.ResultsData from 746 providers from 120 PHCUs were included in the analyses. Baseline role security and therapeutic commitment were found not to influence implementation of brief interventions. Furthermore, there were no significant interactions between these characteristics and allocated implementation groups.ConclusionsThe extent to which providers changed their brief intervention delivery following experience of different implementation strategies was not determined by their initial attitudes towards alcohol problems. In future research, more attention is needed to unravel the causal relation between practitioners’ attitudes, their actual behaviour and care improvement strategies to enhance implementation science.Trial registrationClinicalTrials.gov: NCT01501552 Electronic supplementary materialThe online version of this article (doi:10.1186/s13012-016-0468-5) contains supplementary material, which is available to authorized users.
