Aims: In Denmark, all residents regardless of nationality are ‘de jure’ entitled to a wide range of free-of-charge healthcare services. There is, however, only scarce quantitative knowledge on immigrants’ experiences of their ‘de facto’ access to healthcare and on how access relates to immigrants’ types of residence permits. The study aims to address these gaps. Methods: Survey data on access to healthcare, employment and housing were collected among adult, newly arrived immigrants in Denmark ( n=1711) at 26 publicly contracted Danish language schools in September–December 2021 by national cluster-random sampling stratified by region. Data were analysed using descriptive statistics and multivariate logistic regression. Results: In total, 21% reported general difficulties obtaining good healthcare. Commonly experienced barriers related to financial constraints (39%), communication (37%) and lack of knowledge about the healthcare system (37%). Refugees and their families had higher odds of reporting barriers related to finances (odds ratio (OR) 2.58; confidence interval (CI) 1.77–3.76), communication (OR 3.15; CI 2.39–4.14) and knowledge (OR 1.84; CI 1.16–2.90), while other family reunified immigrants had lower odds of reporting knowledge barriers (OR 0.71; CI 0.54–0.93) compared with immigrants with EU/EEA residence permits, adjusted for gender and residential region. These results remained significant when further adjusted for age, length of stay, education, income, rural/urban residence and household size. Conclusions: Difficulties accessing healthcare are experienced by a large share of newly arrived immigrants in Denmark and are dependent on residence permit type. The findings suggest strengthened efforts to reduce barriers related to finances, communication and knowledge, while focusing on the most vulnerable immigrants.
