Healthcare services for low-wage migrant workers: A systematic review

Low-wage labour migrants often face health-damaging living and working conditions, but are frequently excluded from healthcare. The othering of migrants, bordering of healthcare and simple oversight and negligence create widening health inequalities for a society's essential workers. This review aimed to identify the forms and effectiveness of healthcare services designed to make healthcare accessible for migrant workers. We searched for literature through Medline, Embase, Global Health, Web of Science, and Global Index Medicus (from 1 January 2000 till 9 June 2023), focussing on selected work sectors (domestic work, construction, manufacturing, agriculture, mining). Primary research, reports, and grey literature from 2000 onwards containing descriptions or evaluations of healthcare services exclusively targeting low-wage migrant workers and their families were included. We excluded services focussing only on specific health conditions or disease screening. Quality appraisal was based on tools from the Joanna Briggs Institute. We narratively synthesised service characteristics and effects. This review follows the PRISMA reporting guidelines for systematic reviews and is registered with PROSPERO (CRD42023459360). Identified studies included 21 healthcare services targeting low-wage migrant workers in six countries (China, Dominican Republic, Italy, Qatar, South Africa, USA) in three sectors (agriculture, manufacturing, domestic work). Services included established medical facilities (e.g., general hospital care, semi-permanent primary healthcare (PHC) services); mobile clinics for PHC; and telehealth services. The healthcare services were provided by governmental, non-governmental, academic, and private actors. Most targeted migrant farmworkers and were primarily located in the United States. Common healthcare barriers were addressed, for example, via free care, outreach, or non-traditional hours. However, service effects on health, access and uptake, patient satisfaction, and acceptability were largely unclear, as only six studies offered some fragmentary evaluative evidence. Few healthcare services targeting migrant workers have been documented and evaluated, especially in LMICs. Although migrant workers are deemed to be mobile populations, once in the destination location, many are quite immobile when it comes to accessing healthcare. Thus, in the face of persistent exclusion of migrant workers, health systems cannot simply rely on the ability of this vital workforce to seek and use preventative or curative care, but healthcare services must be actively designed to be accessible to this mobile population in order to ensure health as a human right.
