Prolonged impact of the COVID-19 pandemic on self-harm hospitalizations in France: A nationwide retrospective observational study

Transitions in mental health care utilisation at GHU Paris between 2019 and 2024: A post-pandemic perspective

OBJECTIVE

This study aimed to analyse the long-term evolution of mental health services use following the COVID-19 pandemic.

DESIGN

This was a retrospective study, conducted from 2019 to 2024, using the Groupe Hospitalier Universitaire Paris Psychiatry and Neurosciences (GHU Paris) databases.

METHODS

We considered the number of patients consulting at GHU Paris clinics, number of patients presenting at the emergency department (ED), and number of hospital admissions per week, by sex and age group. We performed a piecewise linear regression, using a threshold approach to identify time patterns between 2019 and 2024: pre-pandemic period (T1), short-term (T2) and long-term post-pandemic period (T3). Temporal changes in mental healthcare service use were then analysed.

RESULTS

No significant overall changes were observed in the number of outpatients after the COVID-19 pandemic, except for a slight increase among patients aged 15-24 years. The number of hospital admissions remained lower in 2024 compared with 2019, with a decreasing trend in T3 for all subgroups. In contrast, the number of ED visits increased over time, with higher use of emergency services by women and young people in 2024 compared with 2019. The overall long-term trend (T3) continued to show an increasing pattern. Additionally, a reduction in schizophrenia presentations was observed, while there was an overall increase in patients with substance use or neurotic disorders.

CONCLUSIONS

Our results described transitions in mental health service use at GHU Paris between 2019 and 2024, highlighting reduced hospital admissions, increased psychiatric emergencies, and changes in the reasons for seeking care.

Risk of admission to hospital for self-harm after admission to hospital for COVID-19: French nationwide longitudinal study

BACKGROUND

Assessing the risk of subsequent self-harm after hospitalisation for COVID-19 is critical for mental health care planning during and after the pandemic.

AIMS

This study aims to compare the risk of admission to hospital for self-harm within 12 months following a COVID-19 hospitalisation during the first half of 2020, with the risk following hospitalisations for other reasons.

METHOD

Using the French administrative healthcare database, logistic regression models were employed to analyse data from patients admitted to hospitals in metropolitan France between January and June 2020. The analysis included adjustments for sociodemographic factors, psychiatric history and the level of care received during the initial hospital stay.

RESULTS

Of the 96 313 patients hospitalised for COVID-19, 336 (0.35%) were subsequently admitted for self-harm within 12 months, compared to 20 135 (0.72%) of 2 797 775 patients admitted for other reasons. This difference remained significant after adjusting for sociodemographic factors (adjusted odds ratio (aOR) = 0.66, 95% CI: 0.59-0.73), psychiatric disorder history (aOR = 0.65, 95% CI: 0.58-0.73) and the level of care received during the initial hospital stay (aOR = 0.70, 95% CI: 0.63-0.78). History of psychiatric disorders and intensive care were strongly correlated with increased risk, while older age was inversely associated with self-harm admissions.

CONCLUSIONS

Hospitalisation for COVID-19 during the early pandemic was linked to a lower risk of subsequent self-harm than hospitalisation for other reasons. Clinicians should consider psychiatric history and intensive care factors in evaluating the risk of future suicide.

Hospitalization for SARS-CoV-2 and the risk of self-harm readmission: a French nationwide retrospective cohort study

AIMS

The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the risk of self-harming behaviours warrants further investigation. Here, we hypothesized that people with a history of hospitalization for self-harm may be particularly at risk of readmission in case of SARS-CoV-2 hospitalization.

METHODS

We conducted a retrospective analysis based on the French national hospitalization database. We identified all patients hospitalized for deliberate self-harm (10th edition of the International Classification of Diseases codes X60-X84) between March 2020 and March 2021. To study the effect of SARS-CoV-2 hospitalization on the risk of readmission for self-harm at 1-year of the inclusion, we performed a multivariable Fine and Gray model considering hospital death as a competing event.

RESULTS

A total of 61,782 individuals were hospitalized for self-harm. During the 1-year follow-up, 9,403 (15.22%) were readmitted for self-harm. Between inclusion and self-harm readmission or the end of follow-up, 1,214 (1.96% of the study cohort) were hospitalized with SARS-CoV-2 (mean age 60 years, 52.9% women) while 60,568 were not (mean age 45 years, 57% women). Multivariate models revealed that the factors independently associated with self-harm readmission were: hospitalization with SARS-CoV-2 (adjusted hazard ratio (aHR) = 3.04 [2.73-3.37]), psychiatric disorders (aHR = 1.61 [1.53-1.69]), self-harm history (aHR = 2.00 [1.88-2.04]), intensive care and age above 80.

CONCLUSIONS

In hospitalized people with a personal history of self-harm, infection with SARS-CoV-2 increased the risk of readmission of self-harm, with an effect that seemed to add to the effect of a history of mental disorders, with an equally significant magnitude. Infection may be a significantly stressful condition that precipitates self-harming acts in vulnerable individuals. Clinicians should pay particular attention to the emergence of suicidal ideation in these patients in the aftermath of SARS-CoV-2 infection.

Patterns of Hospital Presenting Suicide-Related Ideation in Older Adults before and during COVID-19: Findings from a National Clinical Service in Ireland 2018-2021

OBJECTIVE

To examine changes in trends of hospital-presenting suicide-related ideation in older adults living in Ireland, during the first 24 months of the COVID-19 pandemic and 2018-2019.

METHODS

Data on presentations of patients aged 60 and older from participating hospitals of the National Clinical Programme for Self-Harm and Suicide-related Ideation were used to compare trends during the first two years of the COVID-19 pandemic (2020-2021) with the preceding period (2018-2019). Poisson regression models were used to estimate trends in the pre-pandemic and pandemic periods.

RESULTS

There were 1531 presentations for suicide-related ideation to hospital emergency departments in older adults between January 1, 2018-December 31, 2021, with most presentations involving males (57.2%, n = 876). There was a 27% increase in suicide-related ideation presentations during the pandemic years (2020-2021) when compared to 2018-2019 (RR: 1.27, p = .001, 95%CI: 1.14-1.40), with females showing a 29% increase (RR: 1.29, p = .001, 95%CI: 1.11-1.51) and males a 23% increase (RR: 1.23, p = .002, 95%CI: 1.08-1.40). When examining these trends by years, there were only significant increases in 2021, and no significant increases were observed in 2020.

CONCLUSIONS

The study findings show that in the second year following the start of the pandemic, significant increases were observed in suicide-related ideation hospital-presentations in older adults. While immediate changes in trends were not observed in the first year of the pandemic, it is important to consider the pandemic's medium and long-term impact on older adults' mental health, to provide adequate support and reduce suicide risk among those presenting with suicide-related ideation.

Hospitalizations and emergency department visits for self-harm in Canada during the first two years of the COVID-19 pandemic: A time series analysis

BACKGROUND

Rates of hospitalizations and emergency department (ED) visits due to self-harm are important indicators for understanding the impact of the COVID-19 pandemic on mental health. The objective of this study was to assess changes in self-harm hospitalizations and ED visits in Canada during the first two years of the pandemic.

METHODS

Rates of self-harm hospitalizations and ED visits during the pandemic were predicted based on regression analyses that modeled trends over a 5-year pre-pandemic period from fiscal year 2015 to 2019. The ratios of observed and model predicted (expected) rates in 2020 and 2021 were estimated separately to assess changes during the pandemic.

RESULTS

Overall, rates of self-harm hospitalizations and ED visits were lower than expected during the pandemic, especially in 2020. In 2021, rates for females returned to near-expected levels; but they remained lower than expected for males. Females aged 10-14 years had higher than expected rates. The rate ratio of observed rate over expected rate was 1.2 in 2020 but further increased to 1.8 in 2021 for both hospitalizations and ED visits. Higher than expected rates were also observed among females aged 15-19 years in 2021 only.

LIMITATIONS

Suicide attempts and non-suicidal self-harm cases could not be distinguished.

CONCLUSIONS

We observed lower than or close to expected rates of self-harm hospitalizations and ED visits during the pandemic for most population groups. The increased rates for young females highlights the importance of continued surveillance post-pandemic and targeted mental health services and suicide prevention programs.

Self-harm among youth during the first 28 months of the COVID-19 pandemic in Ontario, Canada: a population-based study

BACKGROUND

Youth have reported worsening mental health during the COVID-19 pandemic. We sought to evaluate rates of pediatric acute care visits for self-harm during the pandemic according to age, sex and mental health service use.

METHODS

We conducted a population-based, repeated cross-sectional study using linked health administrative data sets to measure monthly rates of emergency department visits and hospital admissions for self-harm among youth aged 10-17 years between Jan. 1, 2017, and June 30, 2022, in Ontario, Canada. We modelled expected rates of acute care visits for self-harm after the pandemic onset based on prepandemic rates. We reported relative differences between observed and expected monthly rates overall and by age group (10-13 yr and 14-17 yr), sex and mental health service use (new and continuing).

RESULTS

In this population of about 1.3 million children and adolescents, rates of acute care visits for self-harm during the pandemic were higher than expected for emergency department visits (0.27/1000 population v. 0.21/1000 population; adjusted rate ratio [RR] 1.29, 95% confidence interval [CI] 1.19-1.39) and hospital admissions (0.74/10 000 population v. 0.43/10 000 population, adjusted RR 1.72, 95% CI 1.46-2.03). This increase was primarily observed among females. Rates of emergency department visits and hospital admissions for self-harm were higher than expected for both those aged 10-13 years and those aged 14-17 years, as well as for both those new to the mental health system and those already engaged in care.

INTERPRETATION

Rates of acute care visits for self-harm among children and adolescents were higher than expected during the first 2 and a half years of the COVID-19 pandemic, particularly among females. These findings support the need for accessible and intensive prevention efforts and mental health supports in this population.

Risk of hospitalization for self-harm among adults hospitalized with SARS-CoV-2 in France: A nationwide retrospective cohort study

While much work has shown a link between the global SARS-CoV-2 pandemic and poor mental health, little is known about a possible association between hospitalization with SARS-CoV-2 infection and subsequent hospitalization for self-harm. Analyses performed on the French national hospital database between March 2020-March 2021 in 10,084,551 inpatients showed that hospitalization with SARS-CoV-2 infection was not associated with hospitalization for self-harm in the following year. However, hospitalization with SARS-Cov-2 was related to an increased risk of self-harm in patients with a suicidal episode at the inclusion (aHR=1.56[1.14-2.15]), suggesting an effect of SARS-CoV-2 in patients with a recent history of self-harm.

Temporal and spatial trends in suicide-related visits before and during the COVID-19 pandemic in the US, 2018-2021

BACKGROUND

COVID-19 disproportionately impacted mental health in disadvantaged populations and areas. However, disparities in long-term changes in suicide-related visits across the US are unclear. This retrospective study aims to characterize temporal and spatial changes in suicide-related visits in healthcare settings from 2018 to 2021 in the U.S.

METHODS

We use electronic health records for 21,860,370 patients from Healthjump through the COVID-19 Research Database Consortium. Healthjump harmonizes EHR data from over 55 national databases across the US. Suicide ideation and suicide attempts between January 1, 2018 and December 12, 2021 were identified by the diagnosis codes in 6 periods in 2021 compared with the same periods in 2018-2020.

RESULTS

There was 30,019 suicidal ideation, and 7392 suicide attempt visits from January 2018 to November 2021. 15-20-year-olds were the most represented age group at 6302 suicide ideation visits (21.0 % of suicide ideation visits) and 1326 suicide attempt visits (17.9 % of suicide attempt visits), followed by suicide-related visits among 60+ years old. Compared with pre-pandemic periods, youth aged 15-20, females, White, non-Hispanic, and English speakers had increased suicide-related visits, especially suicidal ideation (P < 0.05). Suicide attempts with non-medical substances increased to 28.0 % in the first 6 months of the pandemic in 2020, compared with the prior year (21.5 %). COVID-19 patients had increased suicidal ideation in 2020.

LIMITATIONS

The EHR data is not nationally representative.

CONCLUSIONS

This study found significant and disproportionate increases in suicide related visits over the COVID-19 stages. To prevent the next storms of suicides, future interventions shall accommodate needs among vulnerable groups during and after periods of crisis.

Trends and characteristics of attempted and completed suicides reported to general practitioners before vs during the COVID-19 pandemic in France: Data from a nationwide monitoring system, 2010-2022

BACKGROUND

Most studies published to date have investigated the impact of the COVID-19 pandemic on suicidal acts using hospital data. Trends from primary care in a country such as France are crucial, as individuals may not consult hospital services after suicide attempts (SAs) but rather see their general practitioner (GP).

OBJECTIVES

We aimed to evaluate whether the incidence and characteristics of SAs and completed suicides (CSs) reported to French GPs were different during the COVID-19 pandemic than those of before.

METHODS AND FINDINGS

We conducted a retrospective observational study using data from a nationwide monitoring system, the French Sentinel Network (FSN). All SAs and CSs reported by GPs to the FSN from January 1, 2010, to March 10, 2022 were included. The annual incidence rates (IRs) and the characteristics of SAs and CSs during the pandemic (March 11, 2020, to March 10, 2022) were compared to those of before. In total, 687 SAs and 169 CSs were included. The IRs remained stable for SAs and CSs before and during the pandemic (overlap in confidence intervals). The mean IRs were 52 (95%CI = 44; 57) per 100,000 inhabitants for SAs during the pandemic versus 47 [36; 57] during the pre-pandemic period (p = 0.49), and 5 (95%CI = 2; 9) for CSs versus 11 [6; 16] (p = 0.30). During the pandemic, SA were slightly different from those before in terms of age and occupational status (young/students and older/retirees over-represented), history of consultation and expression of suicidal ideas to GP (more frequent), and CS in terms of occupational status (students over-represented) (p<0.05).

CONCLUSION

The COVID-19 pandemic had no major effect on the overall incidence of SAs and CSs reported to French GPs. However, more suicidal acts were reported among younger and older individuals. Suicidal patients and GPs have adapted by improving the expression of suicidal ideas.

Effect of Obesity among Hospitalized Cancer Patients with or without COVID-19 on a National Level

Cancer and obesity are well-known prognostic factors in COVID-19. Our objective was to study the effect of obesity (and its severity) on the risk of intensive care unit (ICU) admission, severe complications, and in-hospital mortality, in a population of cancer patients hospitalized with or without COVID-19. All patients hospitalized in France for cancer from 1 March 2020 to 28 February 2022 were included from the French national administrative database. The effect of obesity was estimated in COVID-19 and in non-COVID-19 cancer patients using logistic and survival regressions, taking into account age, sex, comorbidities, and different types of cancer. Among the 992,899 cancer patients, we identified 53,090 patients with COVID-19 (5.35%), of which 3260 were obese (6.1%). After adjustment, for patients with or without COVID-19, there is an increased risk of ICU admission or severe complications in obese patients, regardless of the type of obesity. Regarding in-hospital mortality, there is no excess risk associated with overall obesity. However, massive obesity appears to be associated with an increased risk of in-hospital mortality, with a significantly stronger effect in solid cancer patients without COVID-19 and a significantly stronger effect in hematological cancer patients with COVID-19. This study showed that in France, among hospitalized patients with cancer and with or without COVID-19, increased vigilance is needed for obese patients, both in epidemic and non-epidemic periods. This vigilance should be further strengthened in patients with massive obesity for whom the risk of in-hospital mortality is higher, particularly in epidemic periods for patients with hematological cancers.

The 3114: A new professional helpline to swing the French suicide prevention in a new paradigm

Helpline services have been identified as an important component of suicide prevention strategies. While the Covid-19 pandemic has raised major concerns about severe and longstanding mental health consequences, the French Ministry of Health and Prevention has recently decided to implement a national professional helpline dedicated to suicide prevention. The 3114 has been launched on October 1, 2021. Accessible 24/7 from any point of the national territory, it offers remote assistance to individuals in distress or worried about a close one, professionals, and bereaved persons. Spread in regional call centers, medically supervised nurses and psychologists provide callers with listening, evaluation, intervention (including the possible dispatch of a rescue team), and whenever needed, referral to adapted services. At the same time, the "3114 centers" contribute to the implementation of the regional suicide prevention strategies by stimulating the development of actions, promoting resources, monitoring at-risk events, and collaborating with professional and associative stakeholders. From a public health perspective, the inception of the 3114 has settled the conditions for a new paradigm in the French suicide prevention strategy. By dedicating specific resources to promote and organize interactions between stakeholders, it supports a major shift from the juxtaposition of efficient but segregated actions to the creation of an integrated prevention system. Embedded to the project, multidisciplinary and multilevel research will be carried out to evaluate the implementation, impact, and transferability of the 3114 model, conceived both as a helpline and territorial prevention strategy.

Temporal trends in calls for suicide attempts to poison control centers in France during the COVID-19 pandemic: a nationwide study

Concerns have been raised about early vs. later impacts of the COVID-19 pandemic on suicidal behavior. However, data remain sparse to date. We investigated all calls for intentional drug or other toxic ingestions to the eight Poison Control Centers in France between 1st January 2018 and 31st May 2022. Data were extracted from the French National Database of Poisonings. Calls during the study period were analyzed using time trends and time series analyses with SARIMA models (based on the first two years). Breakpoints were determined using Chow test. These analyses were performed together with examination of age groups (≤ 11, 12–24, 25–64, ≥ 65 years) and gender effects when possible. Over the studied period, 66,589 calls for suicide attempts were received. Overall, there was a downward trend from 2018, which slowed down in October 2019 and was followed by an increase from November 2020. Number of calls observed during the COVID period were above what was expected. However, important differences were found according to age and gender. The increase in calls from mid-2020 was particularly observed in young females, while middle-aged adults showed a persisting decrease. An increase in older-aged people was observed from mid-2019 and persisted during the pandemic. The pandemic may therefore have exacerbated a pre-existing fragile situation in adolescents and old-aged people. This study emphasizes the rapidly evolving situation regarding suicidal behaviour during the pandemic, the possibility of age and gender differences in impact, and the value of having access to real-time information to monitor suicidal acts.
