RESUMEN

Researchers and practitioners recognise the importance of context when implementing healthcare interventions, but the influence of wider environment is rarely mapped. This paper identifies the country and policy-related factors potentially explaining the country differences in outcomes of an intervention focused on improving detection and management of heavy alcohol use in primary care in Colombia, Mexico and Peru. Qualitative data obtained through interviews, logbooks and document analysis are used to explain quantitative data on number of alcohol screenings and screening providers in each of the countries. Existing alcohol screening standards in Mexico, and policy prioritisation of primary care and consideration of alcohol as a public health issue in Colombia and Mexico positively contributed to the outcome, while the COVID-19 pandemic had a negative impact. In Peru, the context was unsupportive due to a combination of: political instability amongst regional health authorities; lack of focus on strengthening primary care due to the expansion of community mental health centres; alcohol considered as an addiction rather than a public health issue; and the impact of COVID-19 on healthcare. We found that wider environment-related factors interacted with the intervention implemented and can help explain country differences in outcomes.

RESUMEN

Objective: To measure the impact of the COVID-19 pandemic on the implementation of a program for timely detection, brief intervention, and referral for treatment of alcohol consumption in health centers at the first level of care in Mexico City. Methods: The data were collected at 18 health centers in Mexico City between 2019 and 2021, as part of a larger study. A total of 287 participating health professionals measured their patients' alcohol consumption using the AUDIT-C test. The patients' demographic aspects and consumption patterns were analyzed, as well as care actions (detection, brief intervention, provision of leaflets, monitoring, and referral) at three points in time: before the COVID-19 pandemic, during confinement, and after confinement. Parametric and nonparametric tests were performed to identify the relationship and differences between the variables at the three points. Results: A total of 9090 people who consumed alcohol were identified; detection of consumption fluctuated in the three periods studied (26%, 53%, and 37%, respectively). Medium- and high-risk consumption was more frequent among young men with higher schooling during and after confinement. In the post-confinement period, monitoring and referral actions increased. Conclusions: Measuring the impact of the pandemic on the implementation of a program for timely detection of alcohol consumption, brief intervention, and referral for treatment in health centers helps to develop health policies by age, gender, schooling, and type of consumption at the first level of care.

Objetivo: Medir o efeito da pandemia de COVID-19 na implementação de um programa de detecção oportuna, intervenção breve e encaminhamento para tratamento pelo consumo de álcool em centros de saúde no nível da atenção primária na Cidade do México. Métodos: Foram coletados dados em 18 centros de saúde na Cidade do México entre 2019 e 2021, como parte de um estudo mais amplo. Participaram 287 profissionais de saúde, que mediram o consumo de álcool de seus pacientes com o teste AUDIT-C. Foram analisados aspectos demográficos e o padrão de consumo dos pacientes, bem como as medidas em termos de atendimento (triagem, intervenção breve, entrega de folhetos, monitoramento e encaminhamento) em três momentos: antes da pandemia de COVID-19, durante o confinamento e após o confinamento. Foram feitos testes paramétricos e não paramétricos para identificar a relação e as diferenças entre as variáveis nos três períodos. Resultados: Foram identificadas 9.090 pessoas com consumo de álcool, sendo que a porcentagem de consumo detectada flutuou nos três períodos estudados (26%, 53% e 37%, respectivamente). O consumo de médio e alto risco foi mais prevalente entre homens jovens e com nível maior de escolaridade durante e após o confinamento. No período posterior ao confinamento, as medidas de monitoramento e encaminhamento aumentaram. Conclusões: Medir o impacto da pandemia na implementação de um programa de detecção oportuna, intervenção breve e encaminhamento para tratamento do consumo de álcool em centros de saúde ajuda na formulação de políticas de saúde por idade, gênero, escolaridade e tipo de consumo para o primeiro nível de atenção.

RESUMEN

Alcohol measurement delivered by health care providers in primary health care settings is an efficacious and cost-effective intervention to reduce alcohol consumption among patients. However, this intervention is not yet routinely implemented in practice. Community support has been recommended as a strategy to stimulate the delivery of alcohol measurement by health care providers, yet evidence on the effectiveness of community support in this regard is scarce. The current study used a pre-post quasi-experimental design in order to investigate the effect of community support in three Latin American municipalities in Colombia, Mexico, and Peru on health care providers' rates of measuring alcohol consumption in their patients. The analysis is based on the first 5 months of implementation. Moreover, the study explored possible mechanisms underlying the effects of community support, through health care providers' awareness of support, as well as their attitudes, subjective norms, self-efficacy, and subsequent intention toward delivering the intervention. An ANOVA test indicated that community support had a significant effect on health care providers' rates of measuring alcohol consumption in their patients (F (1, 259) = 4.56, p = 0.034, ηp2 = 0.018). Moreover, a path analysis showed that community support had a significant indirect positive effect on providers' self-efficacy to deliver the intervention (b = 0.07, p = 0.008), which was mediated through awareness of support. Specifically, provision of community support resulted in a higher awareness of support among health care providers (b = 0.31, p < 0.001), which then led to higher self-efficacy to deliver brief alcohol advice (b = 0.23, p = 0.010). Results indicate that adoption of an alcohol measurement intervention by health care providers may be aided by community support, by directly impacting the rates of alcohol measurement sessions, and by increasing providers' self-efficacy to deliver this intervention, through increased awareness of support.

RESUMEN

Background: Initial results from the SCALA study demonstrated that training primary health care providers is an effective implementation strategy to increase alcohol screening in Colombia, Mexico and Peru, but did not show evidence of superior performance for the standard compared to the shorter training arm. This paper elaborates on those outcomes by examining the relationship of training-related process evaluation indicators with the alcohol screening practice. Methods: A mix of convergent and exploratory mixed-methods design was employed. Data sources included training documentation, post-training questionnaires, observation forms, self-report forms and interviews. Available quantitative data were compared on outcome measure - providers' alcohol screening. Results: Training reach was high: three hundred fifty-two providers (72.3% of all eligible) participated in one or more training or booster sessions. Country differences in session length reflected adaptation to previous topic knowledge and experience of the providers. Overall, 49% of attendees conducted alcohol screening in practice. A higher dose received was positively associated with screening, but there was no difference between standard and short training arms. Although the training sessions were well received by participants, satisfaction with training and perceived utility for practice were not associated with screening. Profession, but not age or gender, was associated with screening: in Colombia and Mexico, doctors and psychologists were more likely to screen (although the latter represented only a small proportion of the sample) and in Peru, only psychologists. Conclusions: The SCALA training programme was well received by the participants and led to half of the participating providers conducting alcohol screening in their primary health care practice. The dose received and the professional role were the key factors associated with conducting the alcohol screening in practice.Plain Language Summary: Primary health care providers can play an important role in detecting heavy drinkers among their consulting patients, and training can be an effective implementation strategy to increase alcohol screening and detection. Existing training literature predominantly focuses on evaluating trainings in high-income countries, or evaluating their effectiveness rather than implementation. As part of SCALA (Scale-up of Prevention and Management of Alcohol Use Disorders in Latin America) study, we evaluated training as implementation strategy to increase alcohol screening in primary health care in a middle-income context. Overall, 72.3% of eligible providers attended the training and 49% of training attendees conducted alcohol screening in practice after attending the training. Our process evaluation suggests that simple intervention with sufficient time to practice, adapted to limited provider availability, is optimal to balance training feasibility and effectiveness; that booster sessions are especially important in context with lower organizational or structural support; and that ongoing training refinement during the implementation period is necessary.

RESUMEN

Objetivo. Estimar la razón de costo-efectividad de una intervención breve de cinco pasos dirigida a reducir el estrés y los síntomas depresivos causados por convivir con un consumidor excesivo de alcohol. Métodos. El análisis costo-efectividad se realizó usando un árbol de decisión y se basó en los síntomas depresivos medidos con la escala CES-D. La efectividad de la intervención breve se evaluó comparando un grupo de mujeres indígenas que recibieron la intervención (n = 43) con otro similar sin intervención (n = 30). Los grupos se evaluaron antes, inmediatamente después de la intervención y a los 12 meses y se llevó a cabo en el Estado de Hidalgo, en México. El tratamiento farmacológico fue seleccionado como alternativa de comparación utilizando distintas estimaciones. Para evaluar el valor de la remisión de los síntomas de depresión se emplearon las razones de costo- efectividad y costo-efectividad incremental. Asimismo, se realizaron análisis de sensibilidad. Resultados. La intervención breve resultó ser más efectiva que la farmacológica en la remisión de síntomas depresivos y su costo fue más bajo ($US 31,24 y $US 107,60, respectivamente). Solo si la intervención breve incrementara su costo por encima de 338% o si su efectividad fuera menor de 22,8% dejaría de ser costo-efectiva. Conclusiones. La intervención breve de cinco pasos es una alternativa costo-efectiva con la cual se consiguen reducir significativamente los síntomas de depresión de las mujeres indígenas ocasionados por convivir con un consumidor excesivo de alcohol, así como una opción accesible para la atención de la salud mental en el primer nivel de atención.

Objective. Estimate the cost-effectiveness ratio of a five-step brief intervention aimed at reducing the stress and symptoms of depression caused by living with an alcohol abuser. Methods. The cost-effectiveness analysis was carried out with a decision tree, based on symptoms of depression measured on the CES-D scale. The effectiveness of the brief intervention was evaluated by comparing a group of indigenous women who received the intervention (n = 43) with a similar group who did not (n = 30). The groups were evaluated before, immediately after, and 12 months after the intervention, in the state of Hidalgo (Mexico). Pharmacological treatment was selected for comparison, using different estimates. Cost-effectiveness and incremental cost-effectiveness ratios were used to calculate the value of the remission of depressive symptoms. Sensitivity analyses were also conducted. Results. The brief intervention turned out to be more effective than the pharmacological one in terms of the remission of depressive symptoms. Its cost was also lower ($US 31.24 versus $US 107.60). The brief intervention would cease to be cost-effective only if its cost increased by 338% or more, or if its effectiveness were 22.8% or less. Conclusions. The five-step brief intervention is a cost-effective option that results in significant reductions in depressive symptoms in indigenous women caused by living with alcohol abusers. It is also an affordable option for primary mental health care.
