Immigrant status and likelihood of opioid treatment. Lessons from Spain’s National Health Service
研究利用西班牙初级医疗数据库，分析移民与本地居民在阿片类药物处方上的差异，发现西班牙国家卫生服务下无明显不平等，与美国和加拿大的阿片危机形成对比。
This study investigates opioid prescription patterns among immigrants and native populations in Spain, using novel patient health records from the Base de Datos Clínicos de Atención Primaria (BDCAP). We examined two subsets of data from 2017 and 2018, specifically targeting individuals diagnosed with musculoskeletal (MSK) issues and new cancer diagnoses, as these conditions frequently involve pain management. Our empirical analysis involved estimating a series of linear and count data models to explore the relationship between regions of origin, socioeconomic factors, and the probability of opioid use, controlling for a rich set of health conditions, and primary care centers fixed effects. Despite previously documented healthcare inequities, Spain demonstrates no major differences in opioid prescriptions between immigrants and natives, highlighting the effectiveness of its National Health Service (NHS). This contrasts sharply with the opioid crises in the United States and Canada. The absence of significant disparities underscores the importance of comprehensive healthcare systems and stringent regulations on opioid prescribing practices, as observed in European guidelines. Policy implications include the need to maintain and strengthen public healthcare systems to ensure equitable access to essential medications like opioids and to continue monitoring and regulating opioid prescribing practices to safeguard public health.
