Physical functioning in older persons with somatoform disorders: a pilot study

Comparison of death anxiety symptoms between generalized anxiety disorder and somatization disorder in geriatric patients attending a psychiatric outpatient clinic for the first time

Somatic complaints are among the important complaints frequently seen in Generalized Anxiety Disorder (GAD) and Somatic Symptom Disorder (SSD). Death anxiety has also increased significantly with the Covid-19 pandemic, especially in the elderly population. In this study, we compared the difference of the death anxiety level among patients with GAD, SSD and healthy controls. This cross-sectional study which was carried out in Artvin State Hospital's Psychiatric Outpatient Clinic included 59 participants (GAD = 21, SSD = 18, HC = 20). Three groups were subjected to detailed psychiatric examination by the same psychiatrist. Subsequently, anxiety, somatic symptoms and death anxiety were assessed using standardized tools (GAD-7, Templer Death Anxiety Scale, Somatic Symptom Scale). The GAD-7 Scale mean of the GAD group was significantly higher than SSD (p = 0.001) and Healthy Control (HC) (p = 0.001) groups. Death anxiety and Somatic Symptom levels in GAD and SSD groups were significantly higher than in healthy controls. (GAD, p = 0.001; SSD, p = 0.001) with no significant difference between GAD and SSD groups (p = 1). Healthy controls exhibited significantly lower scores in the three scales mean scores compared to the SSD and GAD groups (p = 0.001). Irrespective of specific psychiatric diagnoses, these findings highlight elevated death anxiety in the elderly, underscoring the need for tailored mental health interventions.

Changes of consultation-liaison psychiatry practice in Italian general hospitals: A comparative 20-year multicenter study

INTRODUCTION

Conducted under the auspices of the Italian Society of Consultation Liaison Psychiatry (SIPC) the aim of this study was to describe the characteristics of Consultation Liaison Psychiatry (CLP) activity in Italy (SIPC-2-2018) over the past 20 years by comparing with data from the first Italian nation-wide study (SIPC-1-1998).

METHODS

We collected data on CLP visits of 3,943 patients from 10 Italian hospitals over a period of 1 year. Data were compared with those from the SIPC-1 1998 study (4,183 participants). Patients were assessed with the same ad hoc 60-item Patient Registration Form recording information from five different areas: Sociodemographic, hospitalization-related, consultation-related, interventions and outcome.

RESULTS

Compared with participants from the previous study, SIPC-2-2018 participants were significantly older (d = 0.54) and hospitalized for a longer duration (d = 0.20). The current study detected an increase in the proportion of referrals from surgical wards and for individuals affected by onco-hematologic diseases. Depressive disorders still represented the most frequent psychiatric diagnosis, followed by adjustment and stress disorders and delirium/dementia. Also, CLP psychiatrists prescribed more often antidepressants (Φ = 0.13), antipsychotics (Φ = 0.09), mood stabilizers (Φ = 0.24), and less often benzodiazepines (Φ = 0.07).

CONCLUSION

CLP workload has increased considerably in the past 20 years in Italy, with changes in patient demographic and clinical characteristics. A trend toward increase in medication-based patient management was observed. These findings suggest that the psychiatric needs of patients admitted to the general hospital are more frequently addressed by referring physicians, although Italian CLP services still deserve better organization and autonomy.

Psychiatric characteristics of older persons with medically unexplained symptoms: A comparison with older patients suffering from medically explained symptoms

BACKGROUND

Empirical studies on the clinical characteristics of older persons with medically unexplained symptoms are limited to uncontrolled pilot studies. Therefore, we aim to examine the psychiatric characteristics of older patients with medically unexplained symptoms (MUS) compared to older patients with medically explained symptoms (MES), also across healthcare settings.

METHODS

A case-control study including 118 older patients with MUS and 154 older patients with MES. To include patients with various developmental and severity stages, patients with MUS were recruited in the community (n = 12), primary care (n = 77), and specialized healthcare (n = 29). Psychopathology was assessed according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria (Mini-International Neuropsychiatric Interview) and by dimensional measures (e.g., psychological distress, hypochondriasis, and depressive symptoms).

RESULTS

A total of 69/118 (58.5%) patients with MUS met the criteria for a somatoform disorder according to DSM-IV-TR criteria, with the highest proportion among patients recruited in specialized healthcare settings (p = 0.008). Patients with MUS had a higher level of psychological distress and hypochondriasis compared to patients with MES. Although psychiatric disorders (beyond somatoform disorders) were more frequently found among patients with MUS compared to patients with MES (42.4 vs. 24.8%, p = 0.008), this difference disappeared when adjusted for age, sex, and level of education (odds ratio = 1.7 [95% confidence interval: 1.0-3.0], p = 0.070).

CONCLUSIONS

Although psychological distress is significantly higher among older patients with MUS compared to those with MES, psychiatric comorbidity rates hardly differ between both patient groups. Therefore, treatment of MUS in later life should primarily focus on reducing psychological distress, irrespective of the healthcare setting patients are treated in.

Pain characteristics of older persons with medically unexplained symptoms, older persons with medically explained symptoms and older persons with depression

OBJECTIVES

The main objective of the current study is to compare chronic pain characteristics of older patients with Medically Unexplained Symptoms (MUS), to those of patients with Medically Explained Symptoms (MES), and to those of patients with Major Depressive Disorder (MDD).

METHOD

By combining data from the OPUS and NESDO study, we compared pain characteristics of 102 older (>60 years) MUS-patients to 145 older MES-patients and 275 older MDD-patients in a case-control study design. Group differences were analyzed using ANCOVA, adjusted for demographic and physical characteristics. Linear regression was applied to examine the association between pain characteristics and somatization (BSI-53 somatization scale) and health anxiety (Whitely Index).

RESULTS

Older MUS-patients have approximately  two times more chance of having chronic pain when compared to older MES-patients (OR = 2.01; p = .013) but equal chances as opposed to MDD-patients. After adjustments, MUS-patients report higher pain intensity and disability scores and more pain locations when compared to MES-patients, but equal values as MDD-patients. Health anxiety and somatization levels were positively associated with the number of pain sites in MUS-patients, but not with pain severity or disability.

CONCLUSION

Older MUS-patients did not differ from MDD-patients with respect to any of the chronic pain characteristics, but had more intense and disabling pain, and more pain locations when compared to older MES-patients.

Assessment of Somatization and Medically Unexplained Symptoms in Later Life

The assessment of medically unexplained symptoms and "somatic symptom disorders" in older adults is challenging due to somatic multimorbidity, which threatens the validity of somatization questionnaires. In a systematic review study, the Patient Health Questionnaire-15 (PHQ-15) and the somatization subscale of the Symptom Checklist 90-item version (SCL-90 SOM) are recommended out of 40 questionnaires for usage in large-scale studies. While both scales measure physical symptoms which in younger persons often refer to unexplained symptoms, in older persons, these symptoms may originate from somatic diseases. Using empirical data, we show that PHQ-15 and SCL-90 SOM among older patients correlate with proxies of somatization as with somatic disease burden. Updating the previous systematic review, revealed six additional questionnaires. Cross-validation studies are needed as none of 46 identified scales met the criteria of suitability for an older population. Nonetheless, specific recommendations can be made for studying older persons, namely the SCL-90 SOM and PHQ-15 for population-based studies, the Freiburg Complaint List and somatization subscale of the Brief Symptom Inventory 53-item version for studies in primary care, and finally the Schedule for Evaluating Persistent Symptoms and Somatic Symptom Experiences Questionnaire for monitoring treatment studies.

Social characteristics and care needs of older persons with medically unexplained symptoms: a case-control study

BACKGROUND

Research in younger patients with medically unexplained symptoms (MUS) has shown impairments in social functioning, such as loneliness and a reduced quality of the patient-doctor relationship. As far as we know, no studies have been performed on social functioning in older MUS patients; self-reported care needs of older MUS patients remain unknown.

OBJECTIVE

To explore social characteristics and care needs of older persons with chronic MUS, when compared to older persons with chronic medically explained symptoms (MES).

METHODS

Patient characteristics of 107 older persons (>60 years) with chronic MUS were compared to 150 older persons with chronic MES in a case-control design. Participants were recruited via advertisements, general practices and a specialized clinic. All participants completed questionnaires on social functioning; the Camberwell Assessment of Need for the Elderly was used to draw up care needs. Linear regression analyses were performed to explore the association between social characteristics and group (MUS/MES), adjusted for demographic and physical determinants. Multiple chi-square tests were performed to detect between-group differences regarding care needs.

RESULTS

After adjustments, older MUS patients were slightly but significantly lonelier, reported a somewhat lower quality of their patient-doctor relationship, but reported equal social support levels when compared to MES patients. MUS patients more often reported unmet care needs regarding health and information provision about their health status.

CONCLUSION

Only small differences in social functioning were found between older MUS and MES patients. Possibly, training future doctors in giving acceptable explanations for the patient's complaints could improve the unmet care need of information provision in older MUS patients.

Health-Related Quality of Life in Older Persons with Medically Unexplained Symptoms

OBJECTIVE

Research on health-related quality of life (HRQoL) in older persons with medically unexplained symptoms (MUS) is scarce, and, in contrast with younger patients, interactions with chronic somatic diseases are more complex.

DESIGN

In the current study we compared HRQoL between older persons with MUS and older persons with medically explained symptoms (MES). Our study sample consisted of 118 older MUS-patients and 154 older MES-patients.

SETTING/MEASUREMENTS

The diagnosis of MUS was ascertained by the general practitioner and confirmed by a geriatrician within a multidisciplinary diagnostic assessment. Additional characteristics, including the HRQoL (Short Form-36), were assessed during a home visit. MES-patients received two home visits to assess all measures. Multiple linear regression analyses, adjusted for age, sex, education, cognitive functioning, and psychiatric diagnoses, were performed to assess the relationship between group (MUS/MES) and HRQoL. Analyses were repeated with additional adjustments for somatization and hypochondriacal cognitions.

RESULTS

Older patients with MUS had a significantly lower level of HRQoL compared with older patients with MES. Even after adjustments, the presence of MUS was still associated with both a lower physical and mental HRQoL. These associations disappeared, however, after additional adjustments for somatization and hypochondriacal cognitions. Within the subgroup of MUS-patients, higher levels of hypochondriac anxiety and of somatization were significantly associated with both lower physical and mental HRQoL.

CONCLUSIONS

Associations between HRQoL and late-life MUS disappear when corrected for somatization and hypochondriacal cognitions, which is in line with the DSM-5 classification of somatic symptom disorder. Appropriate psychological treatment seems needed to improve HRQoL in older MUS-patients.

Multiple somatic symptoms and frailty: cross-sectional study in Japanese community-dwelling elderly people

BACKGROUND

Physical frailty is relevant to adverse outcomes, but appropriate procedures for screening populations are lacking. We hypothesized that frailty is associated with multiple somatic symptoms because frail elderly people might have several somatic symptoms attributed to deterioration of multiple organs.

OBJECTIVE

To examine the association between multiple somatic symptoms and frailty.

METHODS

We conducted a cross-sectional study and enrolled 1818 participants aged ≥60 years from Japanese national medical check-up in 2015. Frailty status was categorized into frail, pre-frail or non-frail based on the definition of the Fried frailty phenotype model. Sixteen self-reported subjective somatic symptoms were recorded at the timing of medical check-up. Odds ratio (OR) and 95% confidence interval (CI) of frail or pre-frail were analyzed using number of somatic symptoms.

RESULTS

Out of total of 1818 subjects, 44 (2.4%) frail subjects, 635 (34.9%) pre-frail subjects and 1139 (62.7%) non-frail subjects were detected. More than two somatic symptoms were significantly associated with the frail phenotype (OR 6.20, 95% CI 2.95, 13.03, P < 0.001) and were associated with the pre-frail phenotype (OR 2.06, 95% CI 1.69, 2.51, P < 0.001). Associations remained significant after multi-adjustment for age, sex, past medical cardiovascular diseases and depressive mood The number of somatic symptoms ≥2 was thought to be the optimal cut-off point to predict frail with a sensitivity of 79.6%, specificity of 61.5%.

CONCLUSIONS

Our study shows that multiple somatic symptoms are independently associated with frailty. Using more than two multiple somatic symptoms as a prescreening tool for frailty may be appropriate.

Big Five personality traits and medically unexplained symptoms in later life

BACKGROUND

Personality dysfunction has been postulated as the most clinically salient problem of persons suffering from medically unexplained symptoms (MUS) but empirical studies are scarce. This study aims to compare the personality profile of older patients suffering from MUS with two comparison groups and a control group.

METHODS

Ninety-six older patients with MUS were compared with 153 frequent attenders in primary care suffering from medically explained symptoms (MES), 255 patients with a past-month depressive disorder (DSM-IV-TR), and a control group of 125 older persons. The Big Five personality domains (NEO-Five-Factor Inventory) were compared between groups by multiple ANCOVAs adjusted for age, sex, education, partner status and cognitive functioning. Linear regression analyses were applied to examine the association between health anxiety (Whitley Index) and somatization (Brief Symptom Inventory).

RESULTS

The four groups differed with respect to neuroticism (P<0.001), extraversion (P<0.001), and agreeableness (P=0.045). Post hoc analyses, showed that MUS patients compared to controls scored higher on neuroticism and agreeableness, and compared to depressed patients lower on neuroticism and higher on extraversion as well agreeableness. Interestingly, MUS and MES patients had a similar personality profile. Health anxiety and somatization were associated with a higher level of neuroticism and a lower level of extraversion and conscientiousness, irrespective whether the physical symptom was explained or not.

CONCLUSIONS

Older patients with MUS have a specific personality profile, comparable to MES patients. Health anxiety and somatization may be better indicators of psychopathology than whether a physical symptom is medically explained or not.

Geriatric characteristics in randomised controlled trials on antidepressant drugs for older adults: a systematic review

OBJECTIVE

Meta-analyses of antidepressant drug treatment trials have found that increasing age is associated with a less favourable outcome. Because the prevalence of geriatric characteristics, like disability, medical co-morbidity, malnutrition, cognitive (dys)function and frailty increase with age and are associated with depression, these characteristics are likely to modify the treatment outcome of antidepressant drugs in late-life depression. This review examines how these five characteristics are taken into account in randomised controlled trials (RCTs) with antidepressant drugs for major depressive disorder in patients aged 60 years or above.

DESIGN

A systematic search in PubMED, PsychInfo and EMBASE, from the year 2000 onwards, yielded 27 RCTs, with a total of 6356 subjects with a median age of 71 years. Two reviewers independently assessed whether each characteristic was considered as inclusion or exclusion criterion, descriptive variable, stratification variable, co-variable, outcome measure, or in adverse effect monitoring.

RESULTS

Malnutrition and frailty were not taken into account in any study. Disability was used as an outcome measure in five studies. Two studies explicitly included a population with possibly serious medical co-morbidity. Cognitive status was the only condition taken into account as co-variable (n = 3) or stratifying variable (n = 1) and was used as outcome measure in seven studies.

CONCLUSIONS

We conclude that geriatric characteristics are rarely taken into account in RCTs on antidepressant drugs in late-life depression, and studies including the oldest adults are underrepresented. This warrants recruitment of the oldest adults and adjustment of treatment strategies in future studies. Copyright © 2016 John Wiley & Sons, Ltd.
