A country-wide health policy in Chile for deaf adults using cochlear implants: Analysis of health determinants and social impacts.

BACKGROUND: Post-lingual deafness represents a critical challenge for adults' well-being with substantial public health burdens. One treatment of choice has been cochlear implants (CI) for people with severe to profound hearing loss (HL). Since 2018, Chile has implemented a high-cost policy to cover CI treatment, the "Ley Ricarte Soto" (LRS) health policy. However, wide variability exists in the use of this device. To date, no related study has been published on policy evaluation in Chile or other Latin American countries. OBJECTIVES: This study aimed to evaluate the impact of the LRS policy on the treatment success and labour market inclusion among deaf or hard of hearing (DHH) adults using CI. We examined and characterised outcomes based on self-reports about treatment success and occupation status between 2018 and 2020. DESIGN: We performed a prospective study using hospital clinical records and an online questionnaire with 76 DHH adults aged >15 who had received CIs since the introduction of the LRS policy in 2018. Using univariate and multivariate regression models, we investigated the relationship between demographic, audiological, and social determinants of health and outcomes, including treatment success for social inclusion (International Outcome inventory for Hearing Aids and CIs assessment: IOI-HA) and occupation status for labour market inclusion. RESULTS: Our study showed elevated levels of treatment success in most of the seven sub-scores of the IOI-HA assessment. Similarly, around 70% of participants maintained or improved their occupations after receiving their CI. We found a significant positive association between treatment success and market inclusion. Participants diagnosed at younger ages had better results than older participants in both outcomes. Regarding social determinants of health, findings suggested participants with high social health insurance and a shorter commute time to the clinic had better results in treatment success. For labour market inclusion, participants with high education levels and better pre- CI occupation had better post-CI occupation status. CONCLUSIONS: In evaluating the LRS policy for providing CIs for DHH adults in Chile, we found positive effects relating to treatment success and occupation status. Our study supports the importance of age at diagnosis and social determinants of health, which should be assessed by integrating public services and bringing them geographically closer to each beneficiary. Although evidence-based guidelines for candidate selection given by the LRS policy might contribute to good results, these guidelines could limit the policy access to people who do not meet the requirements of the guidelines due to social inequalities.

Association between depressive symptoms and all-cause mortality in Chilean adult population: prospective results from two national health surveys.

PURPOSE: Depression is a prevalent disorder with effects beyond mental health. A positive association with mortality has been mostly reported, however, evidence comes from a few high-income countries. This study aims to assess the association between depressive symptoms and all-cause mortality in the Chilean population and assess a potential secular effect in this association. METHODS: This prospective study used data from the Chilean National Health Survey (CNHS). Data from 3151 and 3749 participants from the 2003 and 2010 CNHS, respectively, were linked to mortality register data. Cox survival analysis was performed. The main exposure was depressive symptoms, measured with CIDI-SF (cut-off ≥ 5), and the outcome all-cause mortality. The study period was limited to 8.5 years to allow for the same length of follow-up. RESULTS: 10% and 8.5% of participants from the 2003 and 2010 cohort died during the follow-up. Adjusting for age and sex, those with depressive symptoms had 1.58 (95% CI 1.18-2.13) and 1.65 (95% CI 1.14-2.12) times the risk to die than those without symptoms in the 2003 and 2010 cohort, respectively. In models adjusted for demographic, socioeconomic, behavioural variables and comorbidities, participants with depressive symptoms had 1.42 (95% CI 1.05-1.92) and 1.46 (95% CI 1.07-- 1.99) times the risk to die compared to those without symptoms in the 2003 and 2010 cohort, respectively. CONCLUSION: Chilean adults with depressive symptoms are at higher risk of all-cause mortality compared to those without symptoms. The effect size was similar regardless of the economic development of the country.
