Abstract Objective To analyse the association between survival from critical illness and suicide or self-harm after hospital discharge. Design Population based cohort study using linked and validated provincial databases. Setting Ontario, Canada between January 2009 and December 2017 (inclusive). Participants Consecutive adult intensive care unit (ICU) survivors (≥18 years) were included. Linked administrative databases were used to compare ICU hospital survivors with hospital survivors who never required ICU admission (non-ICU hospital survivors). Patients were categorised based on their index hospital admission (ICU or non-ICU) during the study period. Main outcome measures The primary outcome was the composite of death by suicide (as noted in provincial death records) and deliberate self-harm events after discharge. Each outcome was also assessed independently. Incidence of suicide was evaluated while accounting for competing risk of death from other causes. Analyses were conducted by using overlap propensity score weighted, cause specific Cox proportional hazard models. Results 423 060 consecutive ICU survivors (mean age 61.7 years, 39% women) were identified. During the study period, the crude incidence (per 100 000 person years) of suicide, self-harm, and the composite of suicide or self-harm among ICU survivors was 41.4, 327.9, and 361.0, respectively, compared with 16.8, 177.3, and 191.6 in non-ICU hospital survivors. Analysis using weighted models showed that ICU survivors ( v non-ICU hospital survivors) had a higher risk of suicide (adjusted hazards ratio 1.22, 95% confidence interval 1.11 to 1.33) and self-harm (1.15, 1.12 to 1.19). Among ICU survivors, several factors were associated with suicide or self-harm: previous depression or anxiety (5.69, 5.38 to 6.02), previous post-traumatic stress disorder (1.87, 1.64 to 2.13), invasive mechanical ventilation (1.45, 1.38 to 1.54), and renal replacement therapy (1.35, 1.17 to 1.56). Conclusions Survivors of critical illness have increased risk of suicide and self-harm, and these outcomes were associated with pre-existing psychiatric illness and receipt of invasive life support. Knowledge of these prognostic factors might allow for earlier intervention to potentially reduce this important public health problem.

ObjectivesTo characterise trends in self-poisoning and psychotropic medicine use in young Australians.DesignPopulation-based retrospective cohort study.SettingCalls taken by the New South Wales and Victorian Poisons Information Centres (2006–2016, accounting for 70% of Australian poisoning calls); medicine dispensings in the 10% sample of Australian Pharmaceutical Benefits Scheme data (July 2012 to June 2016).ParticipantsPeople aged 5–19 years.Main outcome measuresYearly trends in intentional poisoning exposure calls, substances taken in intentional poisonings, a prevalence of psychotropic use (dispensing of antidepressants, antipsychotics, benzodiazepines and medicines for attention deficit hyperactivity disorder (ADHD)).ResultsThere were 33 501 intentional poisonings in people aged 5–19 years, with an increase of 8.39% per year (95% CI 6.08% to 10.74%, p<0.0001), with a 98% increase overall, 2006–2016. This effect was driven by increased poisonings in those born after 1997, suggesting a birth cohort effect. Females outnumbered males 3:1. Substances most commonly taken in self-poisonings were paracetamol, ibuprofen, fluoxetine, ethanol, quetiapine, paracetamol/opioid combinations, sertraline and escitalopram. Psychotropic dispensing also increased, with selective serotonin reuptake inhibitors (SSRIs) increasing 40% and 35% July 2012 to June 2016 in those aged 5–14 and 15–19, respectively. Fluoxetine was the most dispensed SSRI. Antipsychotics increased by 13% and 10%, while ADHD medication dispensing increased by 16% and 10%, in those aged 5–14 and 15–19, respectively. Conversely, dispensing of benzodiazepines to these age groups decreased by 4% and 5%, respectively.ConclusionsOur results signal a generation that is increasingly engaging in self-harm and is increasingly prescribed psychotropic medications. These findings indicate growing mental distress in this cohort. Since people who self-harm are at increased risk of suicide later in life, these results may foretell future increases in suicide rates in Australia.

ObjectivesTo compare the risk of death by suicide in male veterans with age-matched civilians.DesignRetrospective cohort study linking provincial administrative databases between 1990 and 2013 with follow-up complete until death or December 31, 2015.SettingPopulation-based study in Ontario, Canada.ParticipantsEx-serving Canadian Armed Forces and Royal Canadian Mounted Police veterans living in Ontario who registered for provincial health insurance were included. A civilian comparator group was matched 4:1 on age and sex.Main outcomeDeath by suicide was classified using standard cause of death diagnosis codes from a provincial registry of mandatory data collected from death certificates. Fine and Gray sub-distribution hazards regression compared the risk of death by suicide between veterans and civilians. Analyses were adjusted for age, residential region, income, rurality and major physical comorbidities.Results20 397 male veterans released to Ontario between 1990 and 2013 and 81 559 age–sex matched civilians were included. 4.2% of veterans died during the study time frame, compared with 6.5% of the civilian cohort. Death by suicide was rare in both cohorts, accounting for 4.6% and 3.6% of veteran and civilian deaths, respectively. After adjustment for confounders, veterans had an 18% lower risk of dying from causes other than suicide (HR 0.82, 95% CI 0.76 to 0.89) and a similar risk of dying by suicide (HR 1.01, 95% CI 0.71 to 1.43), compared with civilians.ConclusionsDeaths by suicide were rare in male veterans residing in Ontario. Our findings demonstrate that veterans had a similar risk of suicide-related mortality as an age-matched civilian population. A better understanding of effective suicide prevention as well as clarifying pathways to seeking and receiving mental health supports and services are important areas for future consideration.

e18577 Background: Psychological distress is a key construct of patient-centred cancer care. While an increased risk of suicide for cancer patients has been reported, more frequent consequences of distress after a cancer diagnosis, such as non-fatal self-injury (NFSI), remain largely unknown. We examined the risk for NFSI after a cancer diagnosis. Methods: Using linked administrative databases we identified adults diagnosed with cancer between 2007-2019. Cumulative incidence of NFSI, defined as emergency department presentation of self-injury, was computed accounting for the competing-risk of death from all causes. Factors associated with NFSI were assessed using multivariable Fine and Gray models. Results: Of 806,910 included patients, 2,482 had NFSI and 182 died by suicide. 5-year cumulative incidence of NFSI was 0.27% [95%CI 0.25-0.28%]. After adjusting for key confounders, prior severe psychiatric illness whether requiring inpatient care (sub-distribution hazard ratio (sHR) 12.6, [95% CI 10.5-15.2]) or outpatient care (sHR 7.5, 95% CI 6.48-8.84), and prior self-injury (sHR 6.6 [95% CI 5.5-8.0]) were associated with increased risk of NFSI. Young adults (age 18-39) had the highest NFSI rates, relative to individuals >70 (sHR 5.4, [95% CI 4.5-6.5]). The magnitude of association between prior severe psychiatric illness and NFSI was greatest for young adults (interaction term p < 0.01). Certain cancer subsites were also at increased risk, including head and neck (sHR1.52, [95%CI 1.19-1.93]). Conclusions: Patients with cancer have higher incidence of NFSI than suicide after diagnosis. Younger age, prior severe psychiatric illness, and prior self-injury were independently associated with NFSI. These exposures act synergistically, placing young adults with a prior mental health history at greatest risk for NFSI events. Those factors should be used to identify at-risk patients for psycho-social assessment and intervention.

SUMMARY To define the incidence of postoperative venous thromboembolism (VTE) and effects of chemotherapy in a population undergoing surgery for esophagogastric cancer. This population-based cohort study used linked primary (Clinical Practice Research Datalink) and secondary (Hospital Episode Statistics) care data from England to identify subjects undergoing esophageal or gastric cancer surgery between 1997 and 2014. Exposures included age, comorbidity, smoking, body mass index, and chemotherapy. Crude rates and adjusted hazard ratios (HRs) were calculated for rate of first postoperative VTE using Cox regression models. The cumulative incidence of VTE at 1 and 6 months was estimated accounting for the competing risk of death from any cause. Of the 2,452 patients identified, 1,012 underwent gastrectomy (41.3%) and 1,440 esophagectomy (58.7%). Risk of VTE was highest in the first month, with absolute VTE rates of 114 per 1,000 person-years (95% CI 59.32–219.10) following gastrectomy and 172.73 per 1,000 person-years (95% CI 111.44–267.74) following esophagectomy. Neoadjuvant and adjuvant chemotherapy was associated with a six-fold increased risk of VTE following gastrectomy, HR 6.19 (95% CI 2.49–15.38). Cumulative incidence estimates of VTE at 6 months following gastrectomy in patients receiving no chemotherapy was 1.90% and esophagectomy 2.21%. However, in those receiving both neoadjuvant and adjuvant chemotherapy, cumulative incidence following gastrectomy was 10.47% and esophagectomy, 3.9%. VTE rates are especially high in the first month following surgery for esophageal and gastric cancer. The cumulative incidence of VTE at 6 months is highest in patients treated with chemotherapy. In this category of patients, targeted VTE prophylaxis may prove beneficial during chemotherapy treatment.

ObjectivesTo describe the percentile distribution of multimorbidity across age by sex, race and ethnicity, and to demonstrate the utility of multimorbidity percentiles to predict mortality.DesignPopulation-based descriptive study and cohort study.SettingOlmsted County, Minnesota (USA).ParticipantsWe used the medical records-linkage system of the Rochester Epidemiology Project (REP; http://www.rochesterproject.org) to identify all residents of Olmsted County, Minnesota who reached one or more birthdays between 1 January 2005 and 31 December 2014 (10 years).MethodsFor each person, we obtained the count of chronic conditions (out of 20 conditions) present on each birthday by extracting all of the diagnostic codes received in the 5 years before the index birthday from the electronic indexes of the REP. To compare each person’s count to peers of same age, the counts were transformed into percentiles of the total population and displayed graphically across age by sex, race and ethnicity. In addition, quintiles 1, 2, 4 and 5 were compared with quintile 3 (reference) to predict the risk of death at 1 year, 5 years and through end of follow-up using time-to-event analyses. Follow-up was passive using the REP.ResultsWe identified 238 010 persons who experienced a total of 1 458 094 birthdays during the study period (median of 6 birthdays per person; IQR 3–10). The percentiles of multimorbidity across age did not vary noticeably by sex, race or ethnicity. In general, there was an increased risk of mortality at 1 and 5 years for quintiles 4 and 5 of multimorbidity. The risk of mortality for quintile 5 was greater for younger age groups and for women.ConclusionsThe assignment of multimorbidity percentiles to persons in a population may be a simple and intuitive tool to assess relative health status, and to predict short-term mortality, especially in younger persons and in women.

Background: There is a lack of knowledge about mortality in eosinophilic esophagitis (EoE). Therefore, this study aimed to examine the mortality in EoE. Methods: A nationwide, population-based matched cohort study was conducted of all EoE patients in Sweden diagnosed between July 2005 and December 2017. Individuals with EoE (n = 1,625) were identified through prospectively recorded histopathology codes from all gastrointestinal pathology reports in Sweden, representing 28 pathology departments (the ESPRESSO study). Each individual with EoE was then matched with up to five reference individuals from the general population (n = 8,003) for age, sex, year of birth, and place of residence. We used the Cox proportional hazard modeling to estimate the adjusted hazard ratio (aHR) and 95% confidence interval (95% CI) while adjusting for other potential confounders. In sensitivity analyses, mortality in EoE patients was compared with mortality in their siblings. Results: Through December 2017, 34 deaths were confirmed in EoE patients (4.60 per 1,000 person-years) compared with 165 in reference individuals (4.57 per 1,000 person-years). This rate corresponds to an aHR of 0.97 (95% CI = 0.67–1.40). HRs were similar in males (aHR = 1.00 [0.66–1.51]) and females (aHR = 0.92 [0.38–2.18]). We observed no increased risk in mortality due to esophageal or other gastrointestinal cancers in patients with EoE (aHR = 1.02 [0.51–2.02]). Mortality was similar in EoE patients and their siblings (aHR = 0.91 [0.44–1.85]). Conclusion: In this nationwide, population-based matched cohort study in Sweden, there was no increased risk of death in patients with EoE compared with their siblings and the general population.

Abstract Objective To investigate whether risk of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and outcomes of coronavirus disease 2019 (covid-19) differed between adults living with and without children during the first two waves of the UK pandemic. Design Population based cohort study, on behalf of NHS England. Setting Primary care data and pseudonymously linked hospital and intensive care admissions and death records from England, during wave 1 (1 February to 31 August 2020) and wave 2 (1 September to 18 December 2020). Participants Two cohorts of adults (18 years and over) registered at a general practice on 1 February 2020 and 1 September 2020. Main outcome measures Adjusted hazard ratios for SARS-CoV-2 infection, covid-19 related admission to hospital or intensive care, or death from covid-19, by presence of children in the household. Results Among 9 334 392 adults aged 65 years and under, during wave 1, living with children was not associated with materially increased risks of recorded SARS-CoV-2 infection, covid-19 related hospital or intensive care admission, or death from covid-19. In wave 2, among adults aged 65 years and under, living with children of any age was associated with an increased risk of recorded SARS-CoV-2 infection (hazard ratio 1.06 (95% confidence interval 1.05 to 1.08) for living with children aged 0-11 years; 1.22 (1.20 to 1.24) for living with children aged 12-18 years) and covid-19 related hospital admission (1.18 (1.06 to 1.31) for living with children aged 0-11; 1.26 (1.12 to 1.40) for living with children aged 12-18). Living with children aged 0-11 was associated with reduced risk of death from both covid-19 and non-covid-19 causes in both waves; living with children of any age was also associated with lower risk of dying from non-covid-19 causes. For adults 65 years and under during wave 2, living with children aged 0-11 years was associated with an increased absolute risk of having SARS-CoV-2 infection recorded of 40-60 per 10 000 people, from 810 to between 850 and 870, and an increase in the number of hospital admissions of 1-5 per 10 000 people, from 160 to between 161 and 165. Living with children aged 12-18 years was associated with an increase of 160-190 per 10 000 in the number of SARS-CoV-2 infections and an increase of 2-6 per 10 000 in the number of hospital admissions. Conclusions In contrast to wave 1, evidence existed of increased risk of reported SARS-CoV-2 infection and covid-19 outcomes among adults living with children during wave 2. However, this did not translate into a materially increased risk of covid-19 mortality, and absolute increases in risk were small.

AbstractBackgroundClose contact with children may provide cross-reactive immunity to SARs-CoV-2 due to more frequent prior coryzal infections from seasonal coronaviruses. Alternatively, close contact with children may increase risk of SARs-CoV-2 infection. We investigated whether risk of infection with SARs-CoV-2 and severe outcomes differed between adults living with and without children.MethodsWorking on behalf of NHS England, we conducted a population-based cohort study using primary care data and pseudonymously-linked hospital and intensive care admissions, and death records, from patients registered in general practices representing 40% of England. Using multivariable Cox regression, we calculated fully-adjusted hazard ratios (HR) of outcomes from 1st February-3rd August 2020 comparing adults living with and without children in the household.FindingsAmong 9,157,814 adults ≤65 years, living with children 0-11 years was not associated with increased risks of recorded SARS-CoV-2 infection, COVID-19 related hospital or ICU admission but was associated with reduced risk of COVID-19 death (HR 0.75, 95%CI 0.62-0.92). Living with children aged 12-18 years was associated with a small increased risk of recorded SARS-CoV-2 infection (HR 1.08, 95%CI 1.03-1.13), but not associated with other COVID-19 outcomes. Living with children of any age was also associated with lower risk of dying from non-COVID-19 causes. Among 2,567,671 adults >65 years there was no association between living with children and outcomes related to SARS-CoV-2. We observed no consistent changes in risk following school closure.InterpretationFor adults living with children there is no evidence of an increased risk of severe COVID-19 outcomes. These findings have implications for determining the benefit-harm balance of children attending school in the COVID-19 pandemic.FundingThis work was supported by the Medical Research Council MR/V015737/1.Research in contextEvidence before this studyWe searched MEDLINE on 19th October 2020 for population-based epidemiological studies comparing the risk of SARS-CoV-2 infection and COVID-19 disease in people living with and without children. We searched for articles published in 2020, with abstracts available, and terms “(children or parents or dependants) AND (COVID or SARS-CoV-2 or coronavirus) AND (rate or hazard or odds or risk), in the title, abstract or keywords. 244 papers were identified for screening but none were relevant. One additional study in preprint was identified on medRxiv and found a reduced risk of hospitalisation for COVID-19 and a positive SARS-CoV-2 infection among adult healthcare workers living with children.Added value of this studyThis is the first population-based study to investigate whether the risk of recorded SARS-CoV-2 infection and severe outcomes from COVID-19 differ between adults living in households with and without school-aged children during the UK pandemic. Our findings show that for adults living with children there is no evidence of an increased risk of severe COVID-19 outcomes although there may be a slightly increased risk of recorded SARS-CoV-2 infection for working-age adults living with children aged 12 to 18 years. Working-age adults living with children 0 to 11 years have a lower risk of death from COVID-19 compared to adults living without children, with the effect size being comparable to their lower risk of death from any cause. We observed no consistent changes in risk of recorded SARS-CoV-2 infection and severe outcomes from COVID-19 comparing periods before and after school closure.Implications of all the available evidenceOur results demonstrate no evidence of serious harms from COVID-19 to adults in close contact with children, compared to those living in households without children. This has implications for determining the benefit-harm balance of children attending school in the COVID-19 pandemic.

ObjectivePatients with alcohol-related liver disease (ALD) are at increased risk of death, but studies have rarely investigated the significance of histological severity or estimated relative risks compared with a general population. We examined mortality in a nationwide cohort of biopsy-proven ALD.DesignPopulation-based cohort study in Sweden comparing 3453 individuals with an International Classification of Disease (ICD) code for ALD and a liver biopsy from 1969 to 2017 with 16 535 matched general population individuals. Swedish national registers were used to ascertain overall and disease-specific mortality, starting follow-up at the latest of first ICD diagnosis or liver biopsy plus 3 months. Cox regression adjusted for relevant confounders was used to estimate HRs in ALD and histopathological subgroups.ResultsMedian age at diagnosis was 58 years, 65% were men and 52% had cirrhosis at baseline. Five-year cumulative mortality was 40.9% in patients with ALD compared with 5.8% in reference individuals. The risk for overall mortality was significantly increased (adjusted HR (aHR)=4.70, 95% CI 4.35 to 5.08). The risk of liver-related death was particularly high (43% of all deaths, aHR=167.6, 95% CI 101.7 to 276.3). Mortality was significantly increased also in patients with ALD without cirrhosis and was highest in the first year after baseline but persisted after ≥10 years of follow-up (aHR=2.74, 95% CI 2.37 to 3.16).ConclusionIndividuals with biopsy-proven ALD have a near fivefold increased risk of death compared with the general population. Individuals with ALD without cirrhosis were also at increased risk of death, reaffirming the need to increase vigilance in the management of these individuals.
