To guide further policy makers, we aimed to estimate, from a societal perspective, the cost of a community based psychiatric intervention for people who inject drugs (PWID). Methods: From March 2022 to May 2022 in Hai Phong, Vietnam, PWID currently or previously diagnosed with a psychiatric disorder were recruited in a 12 months follow-up cohort and received psychiatric and harm-reduction services supported by peers (Drive-Mind 2 cohort study, NCT05886504). Using a micro-costing approach, we estimated the annual per-participant cost for screening PWID for psychiatric disorders, and for providing them for follow-up care and medicine. Findings: All 563 participants who were enrolled in Drive-Mind-2 were screened for psychiatric disorder, and 185 of them were included in a psychiatric follow-up. The total cost of the psychiatric intervention was estimated at $88.7 per participant per year. Recurring goods and services represented 44% of total costs (including medication and transport allowance) and human resources represented 37%. The cost of one screening visit was estimated at $9.8 per participant. Conclusions: Costs for a community-based psychiatric intervention were very low in our study. This data can be used by policy makers in Vietnam to improve a mental health system that is poorly developed and expensive for the patient.","journal":"Frontiers in Psychiatry","year":2025,"id":584130,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.8223,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":969719,"name":"Sao Mai Le","orcid":null,"position":1,"is_corresponding":false},{"id":1497408,"name":"Giang Hoang Thi","orcid":null,"position":2,"is_corresponding":false},{"id":1497409,"name":"Huong Duong Thi","orcid":null,"position":3,"is_corresponding":false},{"id":764874,"name":"Oanh Khuat Thi Hai","orcid":null,"position":4,"is_corresponding":false},{"id":1497410,"name":"Tuyết Thanh Nham Thi","orcid":null,"position":5,"is_corresponding":false},{"id":749682,"name":"Jean‐Pierre Molès","orcid":"0000-0002-6863-6350","position":6,"is_corresponding":false},{"id":749684,"name":"Didier Laureillard","orcid":"0000-0002-0104-9047","position":7,"is_corresponding":false},{"id":22460,"name":"Don C.
