Mortality among inpatients of a psychiatric hospital: Indian perspective

Mortality and cause of death during inpatient psychiatric care in New South Wales, Australia: A retrospective linked data study

BACKGROUND

Premature mortality in people with mental illness is well-documented, yet deaths during inpatient psychiatric care have received little research attention. This study investigates mortality rates and causes of death during inpatient psychiatric care in New South Wales (NSW), Australia. Risk factors for inpatient death were also explored.

METHODS

A retrospective cohort study using linked administrative datasets with complete capture of psychiatric admissions in NSW from 2002 to 2012 (n = 421,580) was conducted. Univariate and multivariate random-effects logistic regression analyses were used to explore risk factors for inpatient death.

RESULTS

The mortality rate during inpatient psychiatric care was 1.12 deaths per 1000 episodes of care and appeared to decline over the study period. Suicide accounted for 17% of inpatient deaths, while physical health causes accounted for 75% of all deaths. Thirty percent of these deaths were considered potentially avoidable. In the multivariate model, male sex, unknown address and several physical health diagnoses were associated with increased deaths.

CONCLUSIONS

The mortality rate and number of avoidable deaths during inpatient psychiatric care were substantial and warrant further systemic investigation. This was driven by a dual burden of physical health conditions and suicide. Strategies to improve access to physical health care on psychiatric inpatient wards and prevent inpatient suicide are necessary. A coordinated approach to monitoring psychiatric inpatient deaths in Australia is not currently available and much needed.

Mortality among psychiatric inpatients in China: A national survey

BACKGROUND

Patients with mental disorders are at increased risk of premature mortality. Psychiatric inpatients are a particularly vulnerable population, yet data on the mortality rate and causes of death among psychiatric inpatients in a national sample are scarce.

METHODS

We analyzed data collected from patients who died during psychiatric hospitalization in 2019 and 2020 from 41 psychiatric hospitals in China.

RESULTS

In total, 719 inpatients died over the study period. There were more deaths in 2019 (N = 409, 56.9%) compared to 2020 (N = 310, 43.1%). The mean age was 73.3 ± 16.5 years old, with males significantly younger than females (71.5 ± 16.9 vs. 75.9 ± 15.6, p < 0.001). Sudden death accounted for 11.5% of all deaths. The cause was unknown for 31.2% of cases. Among those with known causes of death, respiratory disorders were most common in patients with psychotic disorders (41.9%) and mood disorders (29.8%). Suicide accounted for 17.0% of deaths in patients with mood disorders.

CONCLUSION

Patients who died during psychiatric hospitalization were overall older (>70 years), and more than one in ten died due to sudden death. While respiratory disorders accounted for the largest proportion of known causes, the causes were unknown in nearly one-third. Death due to suicide, a preventable cause, remained common among patients with mood disorders. Evidence-based interventions should be implemented.

Observational cohort study of the triggers, diagnoses and outcomes of the medical emergency team (MET) response in adult psychiatry inpatients colocated with acute medical services in Australia

OBJECTIVES

Medical emergencies in psychiatric inpatients are challenging due to the model of care and limited medical resources. The study aims were to determine the triggers and outcomes of a medical emergency team (MET) call in psychiatric wards, and the risk factors for MET activation and mortality.

DESIGN

Retrospective multisite cohort study.

SETTING

Psychiatry units colocated with acute medical services at three major metropolitan hospitals in Melbourne, Australia.

PARTICIPANTS

We studied 487 adult inpatients who experienced a total of 721 MET calls between January 2015 and January 2020. Patients were relatively young (mean age, 45 years) and had few medical comorbidities, but a high prevalence of smoking, excessive alcohol intake and illicit drug use.

OUTCOME MEASURES

We performed a descriptive analysis of the triggers and outcomes (transfer rates, investigations, final diagnosis) of MET calls. We used logistic regression to determine the factors associated with the primary outcome of inpatient mortality, and the secondary outcome of the need for specific medical treatment compared with simple observation.

RESULTS

The most common MET triggers were a reduced Glasgow Coma Scale, tachycardia and hypotension, and 49% of patients required transfer. The most frequent diagnosis was a drug adverse effect or toxidrome, followed by infection and dehydration. There was a strong association between a leave of absence and MET calls, tachycardia and the final diagnosis of drug adverse effects. Mortality occurred in 3% after MET calls. Several baseline and MET clinical variables were associated with mortality but a model with age (per 10 years, OR 1.61, 95% CI 1.29 to 2.01) and hypoxia (OR 3.59, 95% CI 1.43 to 9.04) independently predicted mortality.

CONCLUSION

Vigilance is required in patients returning from day leave, and drug adverse effects remain a challenging problem in psychiatric units. Hypoxic older patients with cardiovascular comorbidity have a higher risk of death.

Socio-demographic and clinical characteristics of patients admitted at the Lunatic Asylum, Bengaluru (now NIMHANS) and treatment outcome in the early 20th century (1903-1911)

OBJECTIVE

Historiography of South Asian mental asylums is generally skewed towards asylums operated by the British. The Lunatic asylum, Bengaluru, later to become NIMHANS, was one of the early asylums and was administered by a princely state (Mysore). This study aims to evaluate socio-demographic and clinical characteristics as well as the treatment outcome of patients admitted to the Lunatic Asylum, Bengaluru in the early 20th century (1903-1911).

METHODS

A review of inpatient registers at the Lunatic Asylum, Bengaluru was conducted for the years 1903-1911 and analysed using descriptive statistical methods.

RESULTS

There were 620 admissions during this period and three-fourths were men (n = 465, 75.0 %). The mean age of the patients was 32.09 ± 10.29 years at the time of admission. Acute mania (n = 209, 33.7 %), chronic mania (n = 125, 20.2 %) and dementia (n = 65, 10.5 %) were the most frequent diagnoses. At the time of discharge, 35.5 % reported being cured and 12.1 % improved. The overall death rate of patients at the asylum was 27.2 %. Subjects who died had a mean duration of in-patient stay of 11.9 years. The mean age at death was 45.7 years with the comparable life-expectancy of the general population during the period being around 23 years.

CONCLUSIONS

In-patients in the Lunatic Asylum, Bengaluru in the pre-antipsychotic era had a good outcome with approximately 50 % being cured or showing improvement and longer life expectancy than the general population.

Mortality characteristics in Sudan in national psychiatric hospitals: 5-year review of hospital mortality

Background

Re-auditing mortality of inpatient psychiatric service for a span of time extending to 14 years is scarce in low-resource countries. We are reporting a 5-year mortality study to complete an audit cycle with a previous 9-year mortality research published a few years ago. It serves to improve the standard of care in low-resource settings.

Results

Out of a total of 7340 (4890 men and 2450 women) admissions to all national psychiatric hospitals in Khartoum over a 5-year period, 36 (23 men and 13 women) patients died while receiving inpatient psychiatric treatment. The mortality rate in this sample was 4.9 (4.7 for men and 5.3 for women). Among all deaths, 30.6% were diagnosed with schizophrenia, while mania constituted 25%, major depression 15% and organic psychosis 11.3%, and 11.1% were considered to be due to alcohol- and/or drug-related disorders. There was no single case of unnatural death in this sample.

Twenty patients (55.6%) died following circulatory failure (sudden death), four (11.1%) as a result of an infection, three (8.3%) from renal failure, two (5.6%) secondarily to NMS, two (5.6%) from diabetic complications and four patients as a result of ECT, GIT bleeding, ischaemic heart disease and alcohol complications.

Conclusion

Circulatory failure and infection are the main causes of death in psychiatric hospitals in Sudan, calling for an intense investigation to resolve these preventable problems.
