Drug type and high risk behaviors associated with health-care utilization among people who inject drugs: a systematic review and meta-analysis.

This study aimed to identify socio-demographic determinants, risky behaviors and type of drug use, and the association with visiting by general practitioners (GP) in the last 12 months or outpatient service use among people who inject drugs (PWID). Studies in English published before November 1 2021, were searched for on PubMed, Scopus, Cochrane, and Web of Science to identify primary studies on the factors associated with visiting by GP or outpatient service use among PWID. After a detailed assessment of over 17,348 papers, a total of 13 studies met the eligibility criteria. Greater odds of visits to the GP in the last 12 months or outpatient service use was associated with (i) being younger, (ii) being female, (iii) employment status, (iv) having public health insurance, (v) individuals who shared needles, (vi) individuals who were prescribed benzodiazepines, (vii) history of taking prescribed mental health medications, (viii) individuals who got methadone maintenance treatment (MMT) and (X) individuals who had used primary care services. The present research findings highlighted that a significant proportion of the study participants used GP or outpatient service use/outpatient psychiatrist, suggesting that the focus should not be restricted to PWID.
