Impact of Training and Municipal Support on Primary Health Care-Based Measurement of Alcohol Consumption in Three Latin American Countries: 5-Month Outcome Results of the Quasi-experimental Randomized SCALA Trial.

PURPOSE: We aimed to test the effects of providing municipal support and training to primary health care providers compared to both training alone and to care as usual on the proportion of adult patients having their alcohol consumption measured. METHODS: We undertook a quasi-experimental study reporting on a 5-month implementation period in 58 primary health care centres from municipal areas within Bogotá (Colombia), Mexico City (Mexico), and Lima (Peru). Within the municipal areas, units were randomized to four arms: (1) care as usual (control); (2) training alone; (3) training and municipal support, designed specifically for the study, using a less intensive clinical and training package; and (4) training and municipal support, designed specifically for the study, using a more intense clinical and training package. The primary outcome was the cumulative proportion of consulting adult patients out of the population registered within the centre whose alcohol consumption was measured (coverage). RESULTS: The combination of municipal support and training did not result in higher coverage than training alone (incidence rate ratio (IRR) = 1.0, 95% CI = 0.6 to 0.8). Training alone resulted in higher coverage than no training (IRR = 9.8, 95% CI = 4.1 to 24.7). Coverage did not differ by intensity of the clinical and training package (coefficient = 0.8, 95% CI 0.4 to 1.5). CONCLUSIONS: Training of providers is key to increasing coverage of alcohol measurement amongst primary health care patients. Although municipal support provided no added value, it is too early to conclude this finding, since full implementation was shortened due to COVID-19 restrictions.

[Cost-effectiveness of a brief intervention to support indigenous women in Hidalgo (Mexico) who live with alcohol abusers]. / Costo-efectividad de una intervención breve de apoyo a mujeres indígenas de Hidalgo, México, que viven con consumidores excesivos de alcohol.

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.

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 cos-to-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.
