RESUMEN
Objective: Lebanon has historically maintained high immunization coverage rates for most routine vaccines. However, an increase in poverty rates coupled with an influx of over a million refugees posed significant challenges to the national immunization program. In response, an accelerated immunization activities (AIA) program, encompassing community-based outreach and referral activities, was launched to increase the demand for childhood vaccination through the public healthcare system. Despite this effort, uptake among refugee and host community households remained low, resulting in pockets of low immunization coverage rates. This study investigates the barriers that prevent households in low coverage areas from vaccinating their children, and evaluates a behavior change intervention designed to overcome the identified social, perceptual, and cognitive barriers. Methods: Households with un- or under-vaccinated children were recruited from seven cadastres with low immunization coverage rates. A mixed methods approach, including stakeholder interviews and field observations, was employed to identify the main barriers to vaccination. Thereafter, a cluster randomized trial was conducted to evaluate the impact of a visual planning aid comprising five behavior change techniques (nudges) on vaccine uptake. Results: A total of 12,332 un- or under-vaccinated children from 6160 households (3045 (49.4%) control households; 3115 (50.6%) treated households) were reached during the trial. The observed vaccination rates were 13.5% and 20.2% for control and treated households, respectively. This represents a 6.7 percentage points increase in the likelihood of a treated household to vaccinate at least one child, compared to the control group. At least 390 additional children benefited from life-saving vaccines due to the behavioral intervention. Conclusions: This study highlights the importance of integrating behavioral insights into vaccination campaigns and programs, especially in low resource settings, to ensure that more children can benefit from life-saving vaccines.
RESUMEN
Objective: In 2015, the Lebanese Ministry of Public Health launched the 2015-2020 National Mental Health Strategy in an effort to integrate Mental Health into Primary Healthcare centers. One of the key objectives of the strategy was to increase the detection, assessment, and management of mental disorders including depression. In addition to diagnosis and patient education, a successful management of depression requires that patients systematically follow-up with their healthcare provider to ensure that they are on the optimal path to recovery. This study evaluates the impact of a visual self-assessment card to increase patients' attendance to a follow-up appointment with their healthcare provider. Methods: A clustered randomized controlled trial was implemented at a Primary Healthcare center located in South Lebanon. The final sample consisted of 405 patients (209 treated and 196 untreated patients) who were diagnosed with mild-to-severe depression using the Patient Health Questionnaire (PHQ-9 > 4). Patients were asked to attend a follow-up appointment with their health provider 2-3 weeks following the initial assessment. Treated patients were provided with a visual self-assessment card that tracked their daily mood changes and reminded them of their follow-up appointment. Results: Overall, the results provide evidence supporting the use of the self-assessment card to remind mental health patients of their follow-up appointments. Patients who received the card were 9 percentage points more likely to attend their follow-up appointment (p = 0.05), with new patients (vs existing patients) exhibiting a 15 percentage points increase (p < 0.05). Conclusion: Efforts focused on increasing compliance with follow-up appointments should be at the cornerstone of mental health integration approaches. Not only do our findings suggest a great potential for cost-effective interventions but also highlight new avenues to optimize on the use of reminders to promote compliance.
