Country and policy factors influencing the implementation of primary care-based alcohol screening: A comparison of Colombia, Mexico and Peru.

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.

Protocol for a process evaluation of SCALA study - Intervention targeting scaling up of primary health care-based prevention and management of heavy drinking and comorbid depression in Latin America.

This paper describes the plan for a process evaluation of a quasi-experimental study testing the municipal level scale-up of primary health care-based measurement and brief advice programmes to reduce heavy drinking and comorbid depression in Colombia, Mexico, and Peru. The main aims of the evaluation are to assess the implementation of intervention components; mechanisms of impact that influenced the outcomes; and characteristics of the context that influenced implementation and outcomes. Based on this information, common drivers of successful outcomes will be identified. A range of data collection methods will be used: questionnaires; interviews; observations; logbooks; and document analysis. All participating providers will complete a pen-and-paper questionnaire at recruitment and two time points during the implementation period. Providers attending training will complete post-training questionnaires. Additionally, 1080 patients will be invited to self-complete a patient questionnaire. One-in-ten participating providers and fifteen other key stakeholders will participate in semi-structured interviews. Training sessions and community advisory board meetings will be observed by a neutral observer. Logbooks will be kept by local research teams to document events affecting the implementation. Project related documentation and other relevant reports describing the context will be examined.

Improving alcohol management in primary health care in Mexico: A return-on-investment analysis.

INTRODUCTION: Alcohol screening, brief advice and referral to treatment (SBIRT) in primary health care is an effective strategy to decrease alcohol consumption at population level. However, there is relatively scarce evidence regarding its economic returns in non-high-income countries. The current paper aims to estimate the return-on-investment of implementing a SBIRT program in Mexican primary health-care settings. METHODS: Empirical data was collected in a quasi-experimental study, from 17 primary health-care centres in Mexico City regarding alcohol screening delivered by 145 health-care providers. This data was combined with data from a simulation study for a period of 10 years (2008 to 2017). Economic investments were calculated from a public sector health-care perspective as clinical consultation costs (salary and material costs) and program costs (set-up, adaptation, implementation strategies). Economic return was calculated as monetary gains in the public sector health-care, estimated via simulated reductions in alcohol consumption, dependent on population coverage of alcohol interventions delivered to primary health-care patients. RESULTS: Results showed that scaling up a SBIRT program in Mexico over a 10-year period would lead to positive return-on-investment values ranging between 21% in scenario 4 (confidence interval -8.6%, 79.5%) and 110% in scenario 5 (confidence interval 51.5%, 239.8%). Moreover, over the 10-year period, up to 16,000 alcohol-related deaths could be avoided as a result of implementing the program. DISCUSSION AND CONCLUSIONS: SBIRT implemented at national level in Mexico may lead to substantial financial gains from a public sector health-care perspective.

Tailoring an evidence-based clinical intervention and training package for the treatment and prevention of comorbid heavy drinking and depression in middle-income country settings: the development of the SCALA toolkit in Latin America.

BACKGROUND: Effective interventions exist for heavy drinking and depression but to date there has been limited translation into routine practice in global health systems. This evidence-to-practice gap is particularly evident in low- and middle-income countries. The international SCALA project (Scale-up of Prevention and Management of Alcohol Use Disorders and Comorbid Depression in Latin America) sought to test the impact of multilevel implementation strategies on rates of primary health care-based measurement of alcohol consumption and identification of depression in Colombia, Mexico, and Peru. OBJECTIVE: To describe the process of development and cultural adaptation of the clinical intervention and training package. METHODS: We drew on Barrero and Castro's four-stage cultural adaption model: 1) information gathering, 2) preliminary adaption, 3) preliminary adaption tests, and 4) adaption refinement. The Tailored Implementation in Chronic Diseases checklist helped us identify potential factors that could affect implementation, with local stakeholder groups established to support the tailoring process, as per the Institute for Healthcare Improvement's Going to Scale Framework. RESULTS: In Stage 1, international best practice guidelines for preventing heavy drinking and depression, and intelligence on the local implementation context, were synthesised to provide an outline clinical intervention and training package. In Stage 2, feedback was gathered from local stakeholders and materials refined accordingly. These materials were piloted with local trainers in Stage 3, leading to further refinements including developing additional tools to support delivery in busy primary care settings. Stage 4 comprised further adaptions in response to real-world implementation, a period that coincided with the onset of the COVID-19 pandemic, including translating the intervention and training package for online delivery, and higher priority for depression screening in the clinical pathway. CONCLUSION: Our experience highlights the importance of meaningful engagement with local communities, alongside the need for continuous tailoring and adaptation, and collaborative decision-making.

Costs of an Alcohol Measurement Intervention in Three Latin American Countries.

Alcohol measurement in health care settings is an effective intervention for reducing alcohol-related harm. However, in many countries, costs related to alcohol measurement have not yet been transparently assessed, which may hinder its adoption and implementation. Costs of an alcohol measurement programme in three upper-middle-income Latin American countries were assessed via questionnaires and compared, as part of the quasi-experimental SCALA study. Additional to the intervention costs, the costs of three implementation strategies: standard training and clinical package, intensive training and clinical package, and community support, were assessed and subsequently translated into costs per additional alcohol measurement session. Results demonstrated that costs for one alcohol measurement session ranged between Int$ 0.67 and Int$ 1.23 in Colombia, Int$ 1.19 and Int$ 2.57 in Mexico, and Int$ 1.11 and Int$ 2.14 in Peru. Costs were mainly driven by the salaries of the health professionals. Implementation strategies costs per additional alcohol measurement session ranged between Int$ 1.24 and Int$ 6.17. In all three countries, standard training and a clinical package may be a promising implementation strategy with a relatively low cost per additional alcohol measurement session.

Perceived appropriateness of alcohol screening and brief advice programmes in Colombia, Mexico and Peru and barriers to their implementation in primary health care - a cross-sectional survey.

BACKGROUND: Providing alcohol screening and brief advice (SBA) in primary health care (PHC) can be an effective measure to reduce alcohol consumption. To aid successful implementation in an upper middle-income country context, this study investigates the perceived appropriateness of the programme and the perceived barriers to its implementation in PHC settings in three Latin American countries: Colombia, Mexico and Peru, as part of larger implementation study (SCALA). METHODS: An online survey based on the Tailored Implementation for Chronic Diseases (TICD) implementation framework was disseminated in the three countries to key stakeholders with experience in the topic and/or setting (both health professionals and other roles, for example regional health administrators and national experts). In total, 55 respondents participated (66% response rate). For responses to both appropriateness and barriers questions, frequencies were computed, and country comparisons were made using Chi square and Kruskal-Wallis non-parametric tests. RESULTS: Alcohol SBA was seen as an appropriate programme to reduce heavy alcohol use in PHC and a range of providers were considered suitable for its delivery, such as general practitioners, nurses, psychologists and social workers. Contextual factors such as patients' normalised perception of their heavy drinking, lack of on-going support for providers, difficulty of accessing referral services and lenient alcohol control laws were the highest rated barriers. Country differences were found for two barriers: Peruvian respondents rated SBA guidelines as less clear than Mexican (Mann-Whitney U = -18.10, P = 0.001), and more strongly indicated lack of available screening instruments than Colombian (Mann-Whitney U = -12.82, P = 0.035) and Mexican respondents (Mann-Whitney U = -13.56, P = 0.018). CONCLUSIONS: The study shows the need to address contextual factors for successful implementation of SBA in practice. General congruence between the countries suggests that similar approaches can be used to encourage widespread implementation of SBA in all three studied countries, with minor tailoring based on the few country-specific barriers.

Prevalence of Substance Use Among Patients of Community Health Centers in East Los Angeles and Tijuana.

BACKGROUND: Given the increased use of psychoactive substances on the United States-Mexico border, a binational study (Tijuana, Mexico-Los Angeles, USA) was conducted to identify the prevalence of substance use in primary care settings. OBJECTIVES: To compare the prevalence and characteristics of patients at risk for substance use disorders in Tijuana and East Los Angeles (LA) community clinics with special attention paid to drug use. METHODS: This was an observational, cross-sectional, analytical study, comparing substance use screening results from patients in Tijuana and LA. The settings were 2 community clinics in LA and 6 in Tijuana. Participants were 2,507 adult patients in LA and 2,890 in Tijuana eligible for WHO Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) screening during March-October 2013. Patients anonymously self-administered the WHO ASSIST on a tablet PC in the clinic waiting rooms. RESULTS: Of eligible patients, 96.4% completed the ASSIST in Tijuana and 88.7% in LA (mean 1.34 minutes and 4.20 minutes, respectively). The prevalence of patients with moderate-to-high substance use was higher in LA than Tijuana for each substance: drugs 19.4% vs. 5.7%, alcohol 15.2% vs. 6.5%, tobacco 20.4% vs. 16.2%. LA patients born in Mexico had 2x the odds and LA patients born in the United States had 6x the odds of being a moderate-to-high drug user compared to Tijuana patients born in Mexico. CONCLUSIONS: Moderate-to-high drug use is higher in LA than in Tijuana but rates are sufficiently high in both to suggest that screening for drug use (along with alcohol and tobacco use) should be integrated into routine primary care of community clinics in both cities.
