The impact of the COVID-19 pandemic on health service utilisation following self-harm: a systematic review

Abstract

Background Evidence on the impacts of the pandemic on healthcare presentations for self-harm has accumulated rapidly. However, existing reviews do not include studies published beyond 2020. Aims To systematically review evidence on health services utilisation for self-harm during the COVID-19 pandemic. Methods A comprehensive search of multiple databases (WHO COVID-19 database, Medline, medRxiv, Scopus, PsyRxiv, SocArXiv, bioRxiv, COVID-19 Open Research Dataset, PubMed) was conducted. Studies reporting presentation frequencies for self-harm published from 1st Jan. 2020 to 7th Sept. 2021 were included. Study quality was assessed using a critical appraisal tool. Results Fifty-one studies were included. 59% (30/51) were rated as low quality, 29% (15/51) as moderate and 12% (6/51) as high-moderate. Most evidence (84%, 43/51 studies) was from high-income countries. 47% (24/51) of studies reported reductions in presentation frequency, including all 6 rated as high-moderate quality, which reported reductions of 17-56%. Settings treating higher lethality self-harm were overrepresented among studies reporting increased demand. Two of the 3 higher quality studies including study observation months from 2021 reported reductions in service utilisation. Evidence from 2021 suggested increased use of health services following self-harm among adolescents, particularly girls. Conclusions Sustained reductions in service utilisation were seen into the first half of 2021. However, evidence from low- and middle-income countries is lacking. The increased use of health services among adolescents, particularly girls, into 2021 is of concern. Our findings may reflect changes in thresholds for help seeking, use of alternative sources of support and variable effects of the pandemic across different groups.

Remote mental health care interventions during the COVID-19 pandemic: An umbrella review

“…Other reviews concluded increased psychiatric hospitalization rates (e.g. for eating disorders) or a mixture of increased or decreased emergency departments visits due to suicidal behaviour (Devoe et al, 2022;John et al, 2021;Samji et al, 2021;Steeg et al, 2022;Tuczyńska, Matthews-Kozanecka, & Baum, 2021). Shorter stay or earlier discharge or release from inpatient mental health care facilities were also frequently mentioned disruptions in multiple reviews (k = 9).…”

A systematic review and meta‐ethnography to explore people's experiences of psychotherapy for self‐harm

“…In the UK, there are around 200,000 hospital attendances for self-harm annually and approximately 50% of those who die by suicide have previously self-harmed (Geulayov et al, 2019). Overall studies do not suggest self-harm rates increased during the COVID-19 pandemic (Kapur et al, 2021;Steeg et al, 2021), though trends may vary by location and there is evidence that help-seeking behaviour may have been affected (Steeg et al, 2022).…”

What happened to the predicted COVID-19-induced suicide epidemic, and why?

“…Presentations of deliberate self-harm (DSH) to health services have also been inconsistent with these predictions. The most recent numbers reported in the International Association for the Study of Pain’s (IASP)s living review showed sustained reductions in service utilisation for DSH up until the first half of 2021 ( Steeg et al, 2022 ).…”
