Risk factors for suicide among older adults with cancer

Risk of suicide in patients with cancer aged 75 years or more - Follow-up of over 400,000 individuals

BACKGROUND

It is well established that older patients with cancer have a significantly higher risk of suicide. However, a comprehensive understanding of the risk factors is lacking. In this study, we aimed to identify groups at an increased risk of suicide among patients aged ≥75 years with a previous cancer diagnosis.

MATERIAL AND METHODS

All Polish individuals diagnosed with cancer at the age of ≥75 years between 1 January 2009 and 31 December 2019 were included in this study. Standardized mortality ratios (SMRs) and 95 % confidence intervals (CIs) were calculated.

RESULTS

A total of 410,440 patients (211,730 men and 198,710 women) were included in this study. SMR for both sexes was 1.64 (95 % CI 1.43-1.87). When analyzed by sex, a significantly higher risk was observed only in men (SMR 1.70, 95 % CI 1.47-1.95). Among them, the risk of suicide was observed after the diagnosis of lymphoma (2.83, 1.14-5.82), lung cancer (2.63, 1.70-3.89), kidney cancer (2.16, 1.03-3.96), colorectal cancer (1.96, 1.41-2.65), urinary tract cancer (1.86, 1.22-2.70), and prostate cancer (1.40, 1.07-1.82). The highest risk of suicide in men was observed within 6 months of diagnosis (2.83, 2.11-3.71).

CONCLUSIONS

Men diagnosed with cancer at ≥75 years of age are at a higher risk of suicide than men of the same age in the general population. The observations from this study suggest which are the most vulnerable groups of elderly patients with cancer, and the time at which they should be given special support.

Oncology Providers' and Professionals' Experiences With Suicide Risk Screening Among Patients With Head and Neck Cancer: A Qualitative Study

PURPOSE

There has been limited study of the implementation of suicide risk screening for patients with head and neck cancer (HNC) as a part of routine care. To address this gap, this study assessed oncology providers' and professionals' perspectives about barriers and facilitators of implementing a suicide risk screening among patients with HNC.

MATERIALS AND METHODS

All patients with HNC with an in-person visit completed a suicide risk screening on an electronic tablet. Patients reporting passive death wish were then screened for active suicidal ideation and referred for appropriate intervention. Interviews were conducted with 25 oncology providers and professionals who played a key role in implementation including nurses, medical assistants, patient access representatives, advanced practice providers, physicians, social workers, and informatics staff. The interview guide was based on the Consolidated Framework for Implementation Research. Interviews were transcribed and analyzed for themes.

RESULTS

Participants identified multilevel implementation barriers, such as intervention level (eg, patient difficulty with using a tablet), process level (eg, limited nursing engagement), organizational level (eg, limited clinic Wi-Fi connectivity), and individual level (eg, low clinician self-efficacy for interpreting and acting upon patient-reported outcome scores). Participants noted facilitators, such as effective care coordination across nursing and social work staff and the opportunity for patients to be screened multiple times. Participants recommended strengthening patient and clinician education and providing patients with other modalities for data entry (eg, desktop computer in the waiting room).

CONCLUSION

Participants identified important intervention modifications that may be needed to optimize suicide risk screening in cancer care settings.

How does social support modify the association between psychological distress and risk of suicide death?

BACKGROUND

Social support (SS) has been reported as a factor preventing suicide death, but whether this association is independent of mental status is unclear. The present study examined the effect modification of SS on the association between psychological distress status and risk of suicide death.

METHODS

Follow-up data for 43,015 subjects participating in a prospective cohort study were analyzed. At baseline, the subjects were asked about SS and mental status with the Kessler six-item Distress (K6) Scale. A Cox model was used to estimate the multivariate-adjusted hazard ratios (HRs) of suicide death according to two levels of psychological distress (K6 ≤ 4, K6 ≥ 5). The HRs in each SS subtype (emotional and instrumental) were also calculated.

RESULTS

There was a significant association between SS and a lower risk of suicide death in the stratum of K6 ≥ 5, with an HR of 0.58 (95% confidence interval, 0.35-0.96). On the other hand, the association with the K6 ≤ 4 strata was not significant.

CONCLUSION

SS appears to be associated with a lower risk of suicide death only among participants with moderate or severe psychological distress. These results imply that early detection of psychological distress and provision of SS is important for preventing suicide death.

Neuropsychiatric Disorders and Frailty in Older Adults over the Spectrum of Cancer: A Narrative Review

BACKGROUND

The interplay between different neuropsychiatric conditions, beyond dementia, in the presence of a diagnosis of cancer in older adults may mediate patients' fitness and cancer-related outcomes. Here, we aimed to investigate the presence of depression, sleep disturbances, anxiety, attitude, motivation, and support in older adults receiving a diagnosis of cancer and the dimension of frailty in order to understand the magnitude of the problem.

METHODS

This review provides an update of the state of the art based on references from searches of PubMed between 2000 and June 2021.

RESULTS

The evidence obtained underscored the tight association between frailty and unfavorable clinical outcomes in older adults with cancer. Given the intrinsic correlation of neuropsychiatric disorders with frailty in the realm of cancer survivorship, the evidence showed they might have a correlation with unfavorable clinical outcomes, late-life geriatric syndromes and higher degree of frailty.

CONCLUSIONS

The identification of common vulnerabilities among neuropsychiatric disorders, frailty, and cancer may hold promise to unmask similar shared pathways, potentially intercepting targeted new interventions over the spectrum of cancer with the delivery of better pathways of care for older adults with cancer.

Suicide and Suicide Attempts in Elderly Patients: An Epidemiological Analysis of Risk Factors and Prevention

A number of elderly patients commit suicide due to the interaction of various factors, including, for example, feelings of loneliness, financial distress, alcohol abuse, chronic pain, progressive diseases, and personality disorders. The data from the EU countries with the highest rates of suicide and suicide attempts among people over 55 years of age warrant the consideration of new approaches to address this social problem.

METHODS

PubMed and other databases, including Polish National data, were used for the analyses.

RESULTS

The average European suicide-attempt rate is 18 per 100 thousand inhabitants. More cases of suicides were reported among those over 55 years of age. Suicide attempts from the year 2012 to 2014 and deaths in 2012 have been reviewed. The risk factors involved in these events, such as depression and social situations including loneliness, health condition, etc., have been discussed to suggest a plausible preventative approach for this important elderly problem.

CONCLUSION

The psychophysiology of elderly persons affected by retirement, socio-economic changes, limited personal autonomy, loneliness, lack of support by the family, and diseases ultimately may lead elderly patients to commit suicide. Thus, financial freedom, family support (respect, love, and care), proper medications, psychological and psychiatric interventions may help the elderly avoid suicidal thoughts and prevent attempts.

Association Between Stroke and Subsequent Risk of Suicide: A Systematic Review and Meta-Analysis

BACKGROUND AND PURPOSE

Poor mental health and depression are well-recognized sequelae of stroke; however, the association between stroke and subsequent risk of suicide is unknown.

METHODS

We systematically searched MEDLINE, Embase, PsycINFO, and Google Scholar from their inception to September 15, 2020, using keywords and database-specific subjects. We independently adjudicated and selected observational studies that reported suicide attempts or death by suicide in stroke survivors and a comparison group, consisting either of people without a history of stroke or the general population. We evaluated study quality using the Newcastle Ottawa scale. Using random-effects meta-analysis, we calculated the pooled adjusted risk ratio (RR) of suicide in stroke survivors and separately calculated the pooled adjusted RR of suicide attempt and death by suicide. Using prespecified analyses, we explored study-level factors to explain heterogeneity.

RESULTS

We screened 4093 articles and included 23 studies of fair quality, totaling over 2 million stroke survivors, of whom 5563 attempted suicide or died by suicide. Compared to the nonstroke group, the pooled adjusted RR of suicide in stroke survivors was 1.73 (95% CI, 1.53-1.96, I²=93%), with a significantly (P=0.03) higher adjusted risk of suicide attempt (RR, 2.11 [1.73-2.56]) than of death by suicide (RR, 1.61 [1.41-1.84]). A longer follow-up time in cohort studies was associated with a lower risk of suicide (RR, 0.97 [0.95-0.99] for every 1-year increase).

CONCLUSIONS

Stroke should be considered as a risk factor for suicide. Comprehensive strategies to screen and treat depression and suicidal ideation in stroke survivors should be developed to reduce the burden of suicide in stroke survivors.

Suicidal death within a year of a cancer diagnosis: A population-based study

BACKGROUND

The suicide risk after a new cancer diagnosis remains a controversial issue. This study examines the suicide risk within the year after a cancer diagnosis. This is the largest study to assess recent trends in suicide risk after a cancer diagnosis.

METHODS

Data were obtained from the Surveillance, Epidemiology, and End Results Program. All patients diagnosed with cancer between 2000 and 2014 were selected. The event was defined as death due to suicide within the first year after a cancer diagnosis, and patients who experienced the event after their diagnosis were observed. The observed/expected (O/E) ratio was assessed as well as the excess risk per 10,000 person-years to determine the suicide risk change after the diagnosis in comparison with the general population.

RESULTS

A total of 4,671,989 patients with cancer were included; 1585 committed suicide within 1 year of their diagnosis. The risk of suicide increased significantly with an O/E ratio of 2.52 and with an excess risk of 2.51 per 10,000 person-years. When the risk of suicide was studied according to the cancer site, the highest increases in the O/E ratio came after diagnoses of pancreatic cancer (8.01) and lung cancer (6.05). The risk of suicide also increased significantly after a diagnosis of colorectal cancer with an O/E ratio of 2.08. However, the risk of suicidal death did not increase significantly after breast and prostate cancer diagnoses.

CONCLUSIONS

The risk of suicide increases significantly in the first year after a diagnosis of cancer in comparison with the general population, and this increase varies with the type and prognosis of cancer. Close observation and referral to mental health services, when indicated, are important for mitigating such risk.

Health-related quality of life of esophageal cancer patients in daily life after treatment: A multicenter cross-sectional study in China

Background

The improvement of diagnostic and therapeutic techniques has prolonged the survival time of patients with esophageal cancer. Little is known, however, about their health‐related quality of life (HRQoL) in daily life after treatment.

Methods

Esophageal cancer patients who had been discharged from hospitals more than one year and healthy controls identified by screening were recruited from seven study centers covering eastern, central, and western regions of China. Patients were categorized into severe dysplasia/carcinoma in situ and stages I, II, III, and IV cancer, respectively. The EQ‐5D was employed to assess HRQoL. Multivariate regression analyses were conducted.

Results

A total of 1456 patients and 2179 controls were recruited. After adjusting for potential confounding factors, the likelihood of reporting problems in the five dimensions of patients was 3.8 to 23.1 times higher than controls, whilst the mean EQ‐5D utility score was 0.311 (95% CI, 0.276‐0.346) lower than controls. The mean utility scores of each patient subgroup were 0.158, 0.289, 0.303, 0.296, and 0.505 (95% CIs: 0.108‐0.208, 0.243‐0.336, 0.261‐0.346, 0.244‐0.347, and 0.437‐0.573) lower than controls, respectively. Patients had the greatest impairment in the self‐care dimension compared with controls, followed by the usual activities dimension. Therapeutic regimen, duration of illness, other chronic disease status, age, and marital status also had significant impact on different aspects of HRQoL in patients.

Conclusions

Esophageal cancer significantly impaired patients' HRQoL in daily life after treatment. Advanced cancer stages were associated with larger decrements on health state utility. Utility scores reported here can facilitate further cost‐utility analyses.

[Cancer and suicide among the elderly: psychosocial determinants of risks, psychopathology and opportunities for prevention]

Suicide is a serious public health problem worldwide. Increasing age is directly associated with the rising rates of cancer and physical and functional limitations are important factors regarded as being associated with suicidal behavior among the elderly. This study sought to conduct a critical review of the literature on the risk factors associated with suicide among elderly cancer patients published between 2000 and 2015. Psychosocial precipitants of risks and psychopathology in 20 selected articles were conducted. The studies consistently identified a number of factors that have been considered to be associated with suicidal behavior among the elderly diagnosed with cancer. These include physical and mental health constraints (particularly major depression), social isolation, and the manner in which these factors and others interact. Further research is needed given the importance of the issue and to examine whether further education for healthcare providers and their abilities in suicide risk assessment and management could have positive effects on reducing the suicide rates among elderly patients with cancer. Considerations for upcoming studies encourage the adoption of empirically supported interventions for individualized management of the elderly cancer patient.

Suicide in Illinois, 2005-2010: A reflection of patterns and risks by age groups and opportunities for targeted prevention

BACKGROUND

Suicide accounts for two thirds of all deaths from intentional or violence-related injury and is a leading cause of death in the United States. Patterns of suicide have been well described among high-risk groups, but few studies have compared the circumstances related to suicides across all age groups. We sought to understand the epidemiology of suicide cases in Illinois and to characterize the risks and patterns for suicide among different age groups.

METHODS

We used suicide data collected from the Illinois Violent Death Reporting System to assess demographics, method of suicide, circumstances, and mental health status among different age groups.

RESULTS

Between 2005 and 2010, 3,016 suicides were reported; 692 (23%) were female, and the median age (n = 3,013) was 45 years (range, 10-98 years). The most common method/weapon types were hanging/strangulation (33%), firearm (32%) and poisoning (21%). Hanging was more common (74%) among young people aged 10 to 19 years, while firearm use was more common among elderly persons age 65 years and older (55%). The percentage of victims within an age group experiencing a crisis within two weeks before committing suicide was highest among 10- to 14-year-olds, while the risk factor of having a family member or friend die in the past 5 years was highest among older victims.

CONCLUSION

The final analysis demonstrated age-related trends in suicide in Illinois, suggesting prevention programs should tailor services by age.

What is the Incidence of Suicide in Patients with Bone and Soft Tissue Cancer? : Suicide and Sarcoma

BACKGROUND

Patients with cancer in the United States are estimated to have a suicide incidence that is approximately twice that of the general population. Patients with bone and soft tissue cancer often have physical impairments and activity limitations develop that reduce their quality of life, which may put them at high risk for depression, anxiety, and suicidal ideation. To our knowledge, there have been no large studies determining incidence of suicide among patients with bone and soft tissue cancer; this information might allow screening of certain high-risk groups.

QUESTIONS/PURPOSES

To determine (1) the incidence of suicide in patients with bone and soft tissue cancer, (2) whether the incidence of suicide is greater in patients with bone and soft tissue cancer than it is in the general US population, and (3) any demographic and tumor characteristics associated with increased suicide incidence.

METHODS

A retrospective analysis of the Surveillance, Epidemiology, and End Results (SEER) program was performed. A total of 23,620 patients with primary bone and soft tissue cancer were identified in this database from 1973 and 2013. Patients with a cause of death listed as "suicide and self-inflicted injury" were considered to have committed suicide and suicide incidences were determined for different demographic and tumor characteristics in this subset of patients. Patient data for age, gender, race, marital status, year of diagnosis, primary cancer site, cancer stage, course of treatment, and survival time were collected and analyzed. The incidence of suicide in patients with bone and soft tissue sarcoma was compared with the age-, gender-, and race-adjusted incidence of suicide in the general US population from 1970 to 2013 available from the National Center for Health Statistics through the SEER Program.

RESULTS

The overall suicide incidence in this population was 32 per 100,000 person-years, which was higher than the age-, race-, and gender-adjusted US general population suicide incidence of 13 per 100,000 person-years. When compared with the incidence of suicide in matched subgroups of the general US population, a higher suicide incidence was observed in men (standardized mortality ratio [SMR], 2.49; 95% CI, 1.92-3.22; p < 0.001), patients of white race (SMR, 2.68; 95% CI, 1.94-3.56; p < 0.001), patients 21 to 30 years old (SMR, 4.40; 95% CI, 3.44-5.54; p < 0.001) and 61 to 70 years old (SMR, 3.27; 95% CI, 2.54-4.18; p < 0.001), patients with cancer of the vertebral column (SMR, 2.88; 95% CI, 2.13-3.83; p < 0.001) and pelvic bones (SMR, 2.75; 95% CI, 2.00-3.65; p < 0.001), and patients within the first 5 years of cancer diagnosis (SMR, 10.8; 95% CI, 9.19-12.61; p < 0.001).

CONCLUSIONS

With identification of these characteristics that are associated with higher incidence of suicide, physicians should consider screening patients possessing these traits. By identifying at-risk patients, we can hope to reduce the incidence of suicide in this population by providing the treatment that these patients need. Further research must be done to determine how best to screen these patients and to identify the best interventions to reduce suicide incidence.

Predictors of suicide attempts in 3.322 patients with affective disorders and schizophrenia spectrum disorders

This study explores risk factors for suicide attempts using the electronic health records of 3322 patients with either schizophrenia spectrum disorders or affective disorders who underwent a comprehensive psychiatric evaluation at the Emergency Department at the Long Island Jewish Medical Center or the Hillside Evaluation Center at The Zucker Hillside Hospital from August 3rd 2011 to July 5th 2012. Multivariate regression analyses showed, after adjusting for sex, that previous suicidal attempts and financial or relationship losses were significantly associated with a current suicidal attempt. Additionally, higher odds of having a suicidal attempt were also found in those subjects with a diagnosis of an affective disorder, compared to a schizophrenia spectrum diagnosis, and those patients in the children/adolescent group compared to those in the adult/elderly group. Our study results confirm and expand results from prior studies. Therefore, physicians should be alert for the presence of any or all of these factors upon evaluation of psychiatric patients, and if present, either psychiatric hospitalization or a close psychiatric follow up in collaboration with family and a therapist would be key in reducing the risk of potential suicidal behavior.

Middle-aged and older adults who had serious suicidal thoughts: who made suicide plans and nonfatal suicide attempts?

BACKGROUND

High suicide rates in late middle-aged and older adults are significant public health problems. Although suicide risk and protective factors are well established, more research is needed about suicide planners and attempters. Using multi-year, national epidemiologic survey data, this study identified correlates of making suicide plans and nonfatal suicide attempts among U.S. adults aged 50+ years.

METHODS

Data are from the 2008 to 2012 U.S. National Survey on Drug Use and Health (NSDUH). Descriptive statistics were used to examine sample characteristics by past-year serious suicidal thoughts, suicide plans, and suicide attempts. Binary logistic regression analyses were used to examine potential correlates (sociodemographic factors, health status, religiosity, psychiatric and substance use disorders (SUDs), and mental health and substance abuse treatment use) of suicide plans and suicide attempts among those who reported serious suicidal thoughts.

RESULTS

Of the 2.5% of the study population that had serious suicidal thoughts (n = 804), 28% made suicide plans and 11.5% attempted suicide. Although 42% of those with serious suicidal thoughts had major depressive episode (MDE), MDE was not significantly associated with suicide plans or attempts in multivariate models. Being employed decreased the odds of making suicide plans, while mental health service use was associated with increased odds of suicide plans. SUDs increased the odds of suicide attempts.

CONCLUSIONS

It is important to screen middle-aged and older adults for severe mental and SUDs and suicidal thoughts and to target interventions for likely planners and attempters.
