Role of Occupational Health Nurses in Mental Health Management: Insights From Supporting Overseas Employees.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe mental health of expatriate employees is a growing concern. While occupational health nurses (OHNs) are well-positioned to coordinate multidisciplinary support, their specific role remains underexplored in international literature.
objectiveThis paper describes OHNs' role in coordinating multidisciplinary mental health support for expatriates. Based on 10 years of experience (2010-2020; N = 450) supporting Japanese engineers across eight international plant construction projects, we characterize this framework through three cases, exploring its feasibility and acceptability over effectiveness.
methodsWe used a descriptive, retrospective design based on routine occupational health work within a Japanese multinational engineering firm. Cases were purposively selected from eight overseas projects in five regional clusters: North Africa (Algeria), Sub-Saharan Africa (South Africa), Southeast Asia (Malaysia), Central Asia and the former Russian bloc (Uzbekistan, Turkmenistan, and Tatarstan), the Caribbean (Trinidad and Tobago), and South America (Chile). Data sources included health records, structured emails, semi-structured manager interviews, and field notes. Outcomes were evaluated using three objective indicators (safe repatriation, absence of significant residual harm, and absence of acute crises), key-informant ratings, and OHN observation notes. Newsletter feedback underwent inductive thematic analysis following Braun and Clarke's framework. The study complied with the Declaration of Helsinki and received ethics approval from Kaito Clinic; individual consent was waived due to the use of de-identified retrospective records.
resultsThree illustrative cases are presented. Case 1 demonstrates the successful emergency aeromedical repatriation and return-to-work of an employee with acute psychiatric illness, aided by the OHN's coordination and a pre-established referral pathway. Case 2 documents the reception of a multilingual monthly newsletter; 90 respondents (≈20% response rate) appreciated the culturally resonant content (55.6%), noted increased service awareness (44.4%), and felt connected to the home team (38.9%). Case 3 describes overseas site visits, rated favorably by 100% (22/22) of interviewed project managers. The three objective indicators were met across all cases, demonstrating practical feasibility and acceptability within this context rather than proven clinical effectiveness.
conclusionsPositioning OHNs as coordinators within a multidisciplinary mental health support team is a feasible and well-accepted approach for Japanese technical employees on overseas assignments. Site visits, multilingual communication, and established referral pathways are practically valuable. Given the retrospective, single-organization design, these findings do not prove clinical effectiveness or generalizability. Further prospective, multi-organizational studies with validated outcome measures are needed to evaluate effectiveness and transferability to other contexts.
