Background Irregular hospital discharge is highly prevalent among people admitted to hospital for mental health reasons. No study has examined the relationship between irregular discharge, post-discharge mortality and treatment setting (i.e. mortality after patients are discharged from acute in-patient or residential mental health settings). Aims To understand the relationship between irregular discharge and mortality among patients discharged from acute in-patient and residential settings. Method A retrospective study was conducted in members of the US veteran population discharged from acute in-patient or residential settings of the US Department of Veterans Affairs between 2003 and 2018. Multivariate Cox proportional hazards were used to evaluate associations between irregular discharge and suicide, external-cause (as defined by ICD-10 Codes: V01-Y98) and all-cause mortality in the first 30-, 90- and 180-days post-discharge. Results There were over 1.5 million mental health discharges between 2003 and 2018. Patients with an irregular discharge were at increased risk for suicide, external-cause and all-cause mortality in the first 180 days after discharge. In the first 30 days after discharge, patients with irregular discharge had more than three times greater suicide risk than patients with regular discharge (adjusted hazard ratio (HR) = 3.41, 95% CI 2.21–5.25). Suicide risk was higher among patients with irregular discharge in the first 30 days after acute in-patient discharge (adjusted HR = 1.55, 95% CI 1.11–2.16). In both settings, the mortality risk associated with irregular discharge attenuated but remained elevated within 90 and 180 days. Conclusions Irregular discharge after an acute in-patient or residential stay poses a large risk for mortality soon after discharge. Clinicians must identify effective interventions to mitigate harms associated with irregular discharge in these settings.

BackgroundThis record linkage study explores the suicide risk of people engaged in caregiving and volunteering. Theory suggests opposing risks as volunteering is associated with better mental health and caregiving with a higher prevalence and incidence of depression.MethodsA 2011 census-based study of 1,018,000 people aged 25–74 years (130,816 caregivers and 110,467 volunteers; 42,099 engaged in both). All attributes were based on census records. Caregiving was categorised as either light (1–19 hours/week) or more intense (20+ hours/week). Suicide risk was based on 45 months of death records and assessed using Cox proportional hazards models with adjustment for and stratification by mental health status at census.ResultsMore intense caregiving was associated with worse mental health (ORadj = 1.15: 95%CI = 1.12, 1.18); volunteering with better mental health (OR 0.87; 95%CIs 0.84, 0.89). The cohort experienced 528 suicides during follow-up. Both volunteering and caregiving were associated with a lower risk of suicide though this was modified by baseline mental ill-health (P = 0.003), HR 0.66; 95%CIs 0.49, 0.88 for those engaged in either activity and with good mental health at baseline and HR 1.02; 95%CIs 0.69, 1.51 for their peers with poor mental health. There was some indication that those engaged in both activities had the lowest suicide risk (HR 0.34; 95%CIs 0.14, 0.84).ConclusionsDespite the poorer mental health amongst caregivers they are not at increased risk of suicide. The significant overlap between caregiving and volunteering and the lower risk of suicide for those engaged in both activities may indicate a synergism of action.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Background: There are limited data regarding the relationship between transport status and mortality in anuric continuous ambulatory peritoneal dialysis (CAPD) patients. Methods: According to the dialysate to plasma creatinine ratio (D/P Cr), 292 anuric CAPD patients were stratified to faster (D/P Cr ≥0.65) and slower transport groups (D/P Cr <0.65). The Cox proportional hazards models were used to evaluate the association of transport status with mortality. Results: During a median follow-up of 22.1 months, 24% patients died, 61.4% of them due to cardiovascular disease (CVD). Anuric patients with faster transport were associated with an increased risk of all-cause mortality (HR (95% CI) = 2.16 (1.09-4.26)), but not cardiovascular mortality, after adjustment for confounders. Faster transporters with pre-existing CVD had a greater risk for death compared to those without any history of CVD. Conclusion: Faster transporters were independently associated with high all-cause mortality in anuric CAPD patients. This association was strengthened in patients with pre-existing CVD.

Introduction: An association between schizophrenia and urbanicity has long been observed, with studies in many countries, including several from Denmark, reporting that individuals born/raised in densely populated urban settings have an increased risk of developing schizophrenia compared to those born/raised in rural settings. However, these findings have not been replicated in all studies. In particular, a Western Australian study showed a gradient in the opposite direction which disappeared after adjustment for covariates. Given the different findings for Denmark and Western Australia, our aim was to investigate the relationship between schizophrenia and urbanicity in these two regions to determine which factors may be influencing the relationship. Methods: We used population-based cohorts of children born alive between 1980 and 2001 in Western Australia ( N = 428,784) and Denmark ( N = 1,357,874). Children were categorised according to the level of urbanicity of their mother’s residence at time of birth and followed-up through to 30 June 2015. Linkage to State-based registers provided information on schizophrenia diagnosis and a range of covariates. Rates of being diagnosed with schizophrenia for each category of urbanicity were estimated using Cox proportional hazards models adjusted for covariates. Results: During follow-up, 1618 (0.4%) children in Western Australia and 11,875 (0.9%) children in Denmark were diagnosed with schizophrenia. In Western Australia, those born in the most remote areas did not experience lower rates of schizophrenia than those born in the most urban areas (hazard ratio = 1.02 [95% confidence interval: 0.81, 1.29]), unlike their Danish counterparts (hazard ratio = 0.62 [95% confidence interval: 0.58, 0.66]). However, when the Western Australian cohort was restricted to children of non-Aboriginal Indigenous status, results were consistent with Danish findings (hazard ratio = 0.46 [95% confidence interval: 0.29, 0.72]). Discussion: Our study highlights the potential for disadvantaged subgroups to mask the contribution of urban-related risk factors to risk of schizophrenia and the importance of stratified analysis in such cases.

Abstract Background Anemia is common in older adults and associated with greater morbidity and mortality. The causes of anemia in older adults have not been completely characterized. Although elevated circulating growth and differentiation factor 15 (GDF-15) has been associated with anemia in older adults, it is not known whether elevated GDF-15 predicts the development of anemia. Methods We examined the relationship between plasma GDF-15 concentrations at baseline in 708 non-anemic adults, aged 60 years and older, with incident anemia during 15 years of follow-up among participants in the Invecchiare in Chianti (InCHIANTI) Study. Results During follow-up, 179 (25.3%) participants developed anemia. The proportion of participants who developed anemia from the lowest to highest quartile of plasma GDF-15 was 12.9%, 20.1%, 21.2%, and 45.8%, respectively. Adults in the highest quartile of plasma GDF-15 had an increased risk of developing anemia (Hazards Ratio 1.15, 95% Confidence Interval 1.09, 1.21, P&lt;.0001) compared to those in the lower three quartiles in a multivariable Cox proportional hazards model adjusting for age, sex, serum iron, soluble transferrin receptor, ferritin, vitamin B12, congestive heart failure, diabetes mellitus, and cancer. Conclusions Circulating GDF-15 is an independent predictor for the development of anemia in older adults.

Background: Elevated levels of serum trimethylamine N-oxide (TMAO) have been previously linked to adverse cardiovascular (CV) and all-cause mortality in hemodialysis patients. However, the clinical significance of serum TMAO levels in patients treated with peritoneal dialysis (PD) is unclear. Methods: A total of 1,032 PD patients with stored serum samples at baseline were enrolled in this prospective study. Serum concentrations of TMAO were quantified by ultra-performance liquid chromatography-tandem mass spectrometry. Cox proportional hazards and competing-risk regression models were performed to examine the association of TMAO levels with all-cause and CV mortality. Results: The median level of serum TMAO in our study population was 34.5 (interquartile range (IQR), 19.8–61.0) μM. During a median follow-up of 63.7 months (IQR, 43.9–87.2), 245 (24%) patients died, with 129 (53%) deaths resulting from CV disease. In the entire cohort, we observed an association between elevated serum TMAO levels and all-cause mortality (adjusted subdistributional hazard ratio [SHR], 1.22; 95% confidence interval [95% CI], 1.01–1.48; p = 0.039) but not CV mortality. Further analysis revealed such association differed by sex; the elevation of serum TMAO levels was independently associated with increased risk of both all-cause (SHR, 1.37; 95% CI, 1.07–1.76; p = 0.013) and CV mortality (SHR, 1.41; 95% CI, 1.02–1.94; p = 0.038) in men but not in women. Conclusions: Higher serum TMAO levels were independently associated with all-cause and CV mortality in male patients treated with PD.

Background: Specialized heart failure (HF) clinics have demonstrated significant reduction in readmission rates. We evaluated a new multi-disciplinary HF clinic focused specifically on those recently discharged from a HF hospitalization. Methods: In this retrospective, cohort study, patients discharged with a primary HF diagnosis who attended the HF post-discharge clinic in 2010-11 were compared with historical controls from 2009. Within an average of six clinic visits, patients were seen by a physician assistant, a clinical pharmacist and a nurse case manager, with care overseen by an attending cardiologist. The clinic focused on identification of HF etiology and precipitating factors, medication titration to target doses, patient education, and medication adherence. The primary outcome was 90-day HF readmission, with secondary outcomes of mortality and a composite of 90-day HF readmission and mortality. A Cox proportional hazards model with adjustment for potentially confounding demographic and comorbidity variables was constructed to compare outcomes between groups. Results: Among the 277 patients (144 clinic and 133 control) in the study, 7.6% of patients in the clinic group and 23.3% of patients in the control group were readmitted for HF within 90 days (aHR 0.26; 95%CI=0.13-0.53 p = 0.0003;aRRR=74%; 95%CI= 47%-87%; ARR=15.7%;NNT=7). There were few deaths, but adjusted all-cause mortality was lower in the clinic group. For the composite of 90-day HF readmission and mortality, clinic patients had a lower risk (9.0% vs 28.6%; aHR 0.23; 95%CI=0.12-0.45; p<0.0001; aRRR=77%; 95%CI=55%-88%;ARR=19.6%;NNT=6). Conclusion: The multidisciplinary HF post-discharge clinic was associated with a significant reduction in 90-day HF readmission rates and all-cause mortality.

Abstract Background Eosinophils are traditionally known as moderators of allergic reactions; however, they have now emerged as one of the principal immune-regulating cells as well as predictors of vascular disease and mortality in the general population. Although eosinophilia has been demonstrated in hemodialysis (HD) patients, associations of eosinophil count (EOC) and its changes with mortality in HD patients are still unknown. Methods In 107 506 incident HD patients treated by a large dialysis organization during 2007–11, we examined the relationships of baseline and time-varying EOC and its changes (ΔEOC) over the first 3 months with all-cause mortality using Cox proportional hazards models with three levels of hierarchical adjustment. Results Baseline median EOC was 231 (interquartile range 155–339) cells/μL and eosinophilia (&gt;350 cells/μL) was observed in 23.4% of patients. There was a gradual increase in EOC over time after HD initiation with a median ΔEOC of 5.1 (IQR −53–199) cells/μL, which did not parallel the changes in white blood cell count. In fully adjusted models, mortality risk was highest in subjects with lower baseline and time-varying EOC (&lt;100 cells/μL) and was also slightly higher in patients with higher levels (≥550 cells/μL), resulting in a reverse J-shaped relationship. The relationship of ΔEOC with all-cause mortality risk was also a reverse J-shape where both an increase and decrease exhibited a higher mortality risk. Conclusions Both lower and higher EOCs and changes in EOC over the first 3 months after HD initiation were associated with higher all-cause mortality in incident HD patients.

BackgroundPulse blood pressure was significantly associated with all-cause mortality in middle-aged and elderly populations, but less evidence was known in young adults.ObjectiveTo assess the association of pulse pressure (PP) with all-cause mortality in young adults.MethodsThis cohort from the 1999–2006 National Health and Nutrition Examination Survey included adults aged 18–40 years. All included participants were followed up until the date of death or 31 December 2015. PP was categorised into three groups: <50, 50~60, ≥60 mm Hg. Cox proportional hazards models and subgroup analysis were performed to estimate the adjusted HRs and 95% CIs for all-cause mortality.ResultsAfter applying the exclusion criteria, 8356 participants (median age 26.63±7.01 years, 4598 women (55.03%)) were included, of which 265 (3.17%) have died during a median follow-up duration of 152.96±30.45 months. When treating PP as a continuous variable, multivariate Cox analysis showed that PP was an independent risk factor for all-cause mortality (HR 1.94, 95% CI 1.02 to 3.69; p=0.0422). When using PP<50 mm Hg as referent, from the 50~60 mm Hg to the ≥60 mm Hg group, the risks of all-cause mortality for participants with PP ranging 50–60 mm Hg or ≥60 mm Hg were 0.93 (95% CI 0.42 to 2.04) and 1.15 (95% CI 0.32 to 4.07) (P for tend was 0.959). Subgroup analysis showed that PP (HR 2.00, 95% CI 1.05 to 3.82; p=0.0360) was associated with all-cause mortality among non-hypertensive participants.ConclusionAmong young adults, higher PP was significantly associated with an increased risk of all-cause mortality, particularly among those without hypertension.

Abstract Background: The soluble isoform of the interleukin-1 receptor family member ST2 (sST2) has been implicated in heart failure. The aim of the present study was to evaluate the capability of sST2 as a prognostic marker in patients with acute destabilized heart failure. Methods: sST2 plasma concentrations were obtained in 137 patients with acute destabilized heart failure attending the emergency department of a tertiary care hospital. The endpoint was defined as all-cause mortality, and the study participants were followed up for 365 days. Results: Of the 137 patients enrolled, 41 died and 96 survived during follow-up. At baseline the median sST2 plasma concentration was significantly higher in the patients who died than in those who survived (870 vs 342 ng/L, P &lt;0.001). Kaplan-Meier curve analyses demonstrated that the risk ratios for mortality were 2.45 (95% CI, 0.88–6.31; P = 0.086) and 6.63 (95% CI, 2.55–10.89; P &lt;0.001) in the second tercile (sST2, 300–700 ng/L; 11 deaths vs 34 survivors) and third tercile (sST2, &gt;700 ng/L; 25 deaths vs 21 survivors) of sST2 plasma concentrations compared with the first tercile (sST2, ≤300 ng/L; 5 deaths vs 41 survivors). In multivariable Cox proportional-hazards regression analyses, an sST2 plasma concentration in the upper tercile was a strong and independent predictor of all-cause mortality. Conclusions: Increased sST2 concentrations determined in plasma samples drawn from patients with acute destabilized heart failure at their initial presentation indicate increased risk of future mortality. Increased sST2 plasma concentrations are independently and strongly associated with one-year all-cause mortality in these patients.

Objective: To evaluate the combined effects of anemia and cognitive function on the risk of all-cause mortality in oldest-old individuals.Design: Prospective population-based cohort study.Setting and Participants: We included 1,212 oldest-old individuals (men, 416; mean age, 93.3 years).Methods: Blood tests, physical examinations, and health questionnaire surveys were conducted in 2012 were used for baseline data. Mortality was assessed in the subsequent 2014 and 2018 survey waves. Cox proportional hazards models were used to evaluate anemia, cognitive impairment, and mortality risk. We used restricted cubic splines to analyze and visualize the association between hemoglobin (Hb) levels and mortality risk.Results: A total of 801 (66.1%) deaths were identified during the 6-year follow-up. We noted a significant association between anemia and mortality (hazard ratio [HR] 1.32, 95% confidence interval [CI] 1.14–1.54) after adjusting for confounding variables. We also observed a dose-response relationship between the severity of anemia and mortality (P &lt; 0.001). In the restricted cubic spline models, Hb levels had a reverse J-shaped association with mortality risk (HR 0.88, 95% CI 0.84–0.93 per 10 g/L-increase in Hb levels below 130 g/L). The reverse J-shaped association persisted in individuals without cognitive impairment (HR 0.88, 95% CI 0.79–0.98 per 10 g/L-increase in Hb levels below 110 g/L). For people with cognitive impairment, Hb levels were inversely associated with mortality risk (HR 0.83, 95% CI 0.78–0.89 per 10 g/L-increase in Hb levels below 150 g/L). People with anemia and cognitive impairment had the highest risk of mortality (HR 2.60, 95% CI 2.06–3.27).Conclusion: Our results indicate that anemia is associated with an increased risk of mortality in oldest-old people. Cognitive impairment modifies the association between Hb levels and mortality.
