Abnormal Illness Behavior, Alexithymia, Demoralization, and Other Clinically Relevant Psychosocial Syndromes in Kidney Transplant Recipients: A Comparative Study of the Diagnostic Criteria for Psychosomatic Research System versus ICD-10 Psychiatric Nosology

Illness Denial in Medical Disorders: A Systematic Review

INTRODUCTION

Illness denial pertains to medical patients who do not acknowledge the presence or severity of their disease or the need of treatment.

OBJECTIVE

This systematic review was performed to clarify the clinical role and manifestations of illness denial, its impact on health attitudes and behavior, as well as on short- and long-term outcomes in patients with medical disorders.

METHODS

The systematic search according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines was conducted on PubMed, Scopus, and Web of Science.

RESULTS

The initial search yielded a total of 14,098 articles; 176 studies met the criteria for inclusion. Illness denial appeared to be a relatively common condition affecting a wide spectrum of health attitudes and behavior. In some cases, it may help a person cope with various stages of illness and treatment. In other situations, it may determine delay in seeking treatment, impaired adherence, and reduced self-management, leading to adverse outcomes. The Diagnostic Criteria for Psychosomatic Research (DCPR) were found to set a useful severity threshold for the condition. An important clinical distinction can also be made based on the DCPR for illness denial, which require the assessment of whether the patient has been provided with an adequate appraisal of the medical situation.

CONCLUSIONS

This systematic review indicates that patients with medical disorders experience and express illness denial in many forms and with varying degrees of severity. The findings suggest the need for a multidimensional assessment and provide challenging insights into the management of medical disorders.

Psychosocial determinants of healthcare use costs in kidney transplant recipients

Introduction

Psychosocial factors frequently occur in kidney transplant recipients (KTRs), leading to behavioral alterations and reduced therapeutic adherence. However, the burden of psychosocial disorders on costs for KTRs is unknown. The aim of the study is to identify predictors of healthcare costs due to hospital admissions and emergency department access in KTRs.

Methods

This is a longitudinal observational study conducted on KTRs aged >18 years, excluding patients with an insufficient level of autonomy and cognitive disorder. KTRs underwent psychosocial assessment via two interviews, namely the Mini-International Neuropsychiatric Interview 6.0 (MINI 6.0) and the Diagnostic Criteria for Psychosomatic Research Interview (DCPR) and via the Edmonton Symptom Assessment System Revised (ESAS-R) scale, a self-administrated questionnaire. Sociodemographic data and healthcare costs for hospital admissions and emergency department access were collected in the 2016-2021 period. Psychosocial determinants were as follows: (1) ESAS-R psychological and physical score; (2) symptomatic clusters determined by DCPR (illness behavior cluster, somatization cluster, and personological cluster); and (3) ICD diagnosis of adjustment disorder, anxiety disorder, and mood disorder. A multivariate regression model was used to test the association between psychosocial determinants and total healthcare costs.

Results

A total of 134 KTRs were enrolled, of whom 90 (67%) were men with a mean age of 56 years. A preliminary analysis of healthcare costs highlighted that higher healthcare costs are correlated with worse outcomes and death (p < 0.001). Somatization clusters (p = 0.020) and mood disorder (p < 0.001) were positively associated with costs due to total healthcare costs.

Conclusions

This study showed somatization and mood disorders could predict costs for hospital admissions and emergency department access and be possible risk factors for poor outcomes, including death, in KTRs.

Frailty and the psychosocial components of the edmonton frail scale are most associated with patient experience in older kidney transplant candidates - a secondary analysis within the kidney transplantation in older people (KTOP) study

Background

Older people with end-stage kidney disease (ESKD) are vulnerable to frailty, which impacts on clinical and experiential outcomes. With kidney transplantation in older people increasing, a better understanding of patient experiences is necessary for guiding decision making. The Kidney Transplantation in Older People (KTOP):impact of frailty on outcomes study aims to explore this. We present a secondary analysis of the Edmonton Frail Scale (EFS) and its relationship with patient experience scores.

Methods

The KTOP study is a single centre, prospective study, which began in October 2019. All ESKD patients aged ≥60 considered for transplantation at Imperial College Renal and Transplant Centre were eligible. Frailty was assessed using the EFS and 5 questionnaires assessed patient experience and quality of life (QoL) (Short Form-12(v2), Palliative Care Outcome Scale-Symptoms Renal, Depression Patient Health Questionnaire-9, Illness Intrusiveness Ratings Scale, Renal Treatment Satisfaction Questionnaire). The EFS was divided into 4 subdomains (psychosocial, physical function, medical status, and general health) and then compared with the questionnaire scores.

Results

210 patients have been recruited (aged 60-78), 186 of whom completed EFS assessments. 118 (63.4%) participants were not frail, 36 (19.4%) vulnerable, and 32 (17.2%) were frail. Worse frailty scores were associated with poorer patient experience and QoL scores across all questionnaires. Severe deficits in the EFS psychosocial subdomain showed a statistically significant association with higher depression screen scores (coefficient 4.9, 95% CI 3.22 to 6.59), lower physical (coefficient -4.35, 95% CI -7.59 to -1.12) and mental function scores (coefficient -8.33, 95% CI -11.77 to -4.88) from the Short Form-12(v2), and lower renal treatment satisfaction scores (coefficient -5.54, 95% CI -10.70 to -0.37). Deficits in the physical function and medical status EFS subdomians showed some association with patient experience scores.

Conclusion

In the KTOP study cohort at recruitment vulnerable and frail candidates reported worse QoL and patient experiences. Severe deficits in the psychosocial subdomains of the EFS showed a strong association with patient experience and QoL, whilst physical function and medical status deficits showed a lesser association. This has highlighted specific EFS domains that may be suitable for targeted interventions to improve experiences and optimise outcomes.

Exploring the Level of Post Traumatic Growth in Kidney Transplant Recipients via Network Analysis

Although kidney transplant can lead to psychiatric disorders, psychosocial syndromes and demoralization, a positive post-traumatic growth (PTG) can occur in kidney transplant recipients (KTRs). However, the PTG-Inventory (PTGI), a reliable tool to measure PTG is scarcely used to explore the effect of this stressful event in KTRs. Thus, the purpose of our study was to assess the level of PTG and its correlation with demoralization, physical and emotional symptoms or problems via network analysis in KTRs. Additionally, we aimed at exploring the association of PTG with psychiatric diagnoses, Diagnostic Criteria for Psychosomatic Research (DCPR) conditions, and medical variables. A total of 134 KTRs were tested using MINI International Neuropsychiatric Interview 6.0 (MINI 6.0), DCPR interview, PTGI, Edmonton Symptom Assessment System (ESAS), Canadian Problem Checklist (CPC) and Demoralization scale (DS-IT). PTGI was used to investigate the positive psychological experience of patients after KT. It consists of 21 items divided in five factors. Routine biochemistry, immunosuppressive agents, socio-demographic and clinical data were collected. A symptom network analysis was conducted among PTGI, ESAS and DS-IT. Mean score of PTGI total of sample was 52.81 ± 19.81 with higher scores in women (58.53 ± 21.57) than in men (50.04 ± 18.39) (p < 0.05). PTGI-Relating to Others (16.50 ± 7.99) sub-score was markedly higher than other PTGI factor sub-scores. KTRs with DCPR-alexithymia or International Classification of Diseases, tenth revision (ICD-10) anxiety disorders diagnosis had lower PTGI total score and higher PTGI-Personal Strength sub-score, respectively (p < 0.05). The network analysis identified two communities: PTGI and ESAS with DS-IT. DS-IT Disheartenment, DS-IT Hopelessness and PTGI Relating to Others were the most central items in the network. After 1000 bootstrap procedures, the Exploratory graph analysis revealed the presence of a median of two communities in the network in 97.5% of the bootstrap iterations. A more extensive use of PTGI should be encouraged to identify and enhance the positive psychological changes after KT.

Psychosocial Dimensions in Hemodialysis Patients on Kidney Transplant Waiting List: Preliminary Data

Although the donation rate for deceased and living kidneys has been increasing, the donor organ availability meets only the 30% of kidney needs in Italy. Consequently, hemodialysis patients stay for a long time, an average of 3.2 years, on a waiting list for a kidney transplant with consequent relevant psychological distress or even full-fledged psychiatric disorders, as diagnosed with traditional psychiatric nosological systems. Recent studies report, however, a higher prevalence of other psychosocial syndromes, as diagnosed by using the Diagnostic Criteria for Psychosomatic Research (DCPR) in medically ill and kidney transplant patients. Nevertheless, no data regarding DCPR prevalence are available in patients waitlisted for a renal transplant (WKTs). Thus, the primary aim of this study was to identify sub-threshold or undetected syndromes by using the DCPR and, secondly, to analyze its relationship with physical and psychological symptoms and daily-life problems in WKTs. A total of 30 consecutive WKTs were assessed using the DCPR Interview and the MINI International Neuropsychiatric Interview 6.0. The Edmonton Symptom Assessment System (ESAS) and the Canadian Problem Checklist were used to assess physical and psychological distress symptoms and daily-life problems. A total of 60% of patients met the criteria for at least one DCPR diagnosis; of them, 20% received one DCPR diagnosis (DCPR = 1), and 40% more than one (DCPR > 1), especially the irritability cluster (46.7%), Abnormal Illness Behavior (AIB) cluster (23.3%) and somatization cluster (23.3%). Fifteen patients met the criteria for an ICD diagnosis. Among patients without an ICD-10 diagnosis, 77.8% had at least one DCPR syndrome (p < 0.05). Higher scores on ESAS symptoms (i.e., tiredness, nausea, depression, anxiety, feeling of a lack of well-being and distress), ESAS-Physical, ESAS-Psychological, and ESAS-Total were found among DCPR cases than DCPR non-cases. In conclusion, a high prevalence of DCPR diagnoses was found in WKTs, including those who resulted to be ICD-10 non-cases. The joint use of DCPR and other screening tools (e.g., ESAS) should be evaluated in future research as part of a correct psychosocial assessment of WKTs.

Incremental Validity Of The Diagnostic Criteria For Psychosomatic Research - Revised (DCPR-R) To Clinical Assessment In Primary Care

Psychosocial problems are highly prevalent among primary care (PC) patients, but they often remain undetected using traditional classification systems. The aim of the present study was to test the incremental validity of the revised version of the Diagnostic Criteria for Psychosomatic Research (DCPR-R), in addition to standard psychiatric assessment based on DSM-5, with regard to the prediction of psychosocial functioning of PC patients. Two-hundred PC patients were consecutively recruited. A comprehensive assessment was performed using two clinical interviews and three self-rating questionnaires (the PsychoSocial Index [PSI], the Short-Form Health Survey [SF-12] and the Illness Attitude Scales [IAS]) for the assessment of psychopathology and psychosocial functioning. Adding the DCPR-R to DSM-5, the amount of explained variance significantly increased by 9% to 16% in the PSI subscales, by 13% in the SF-12 mental component summary, and by 2% to 6% in the IAS scales. The joint use of DCPR-R and DSM-5 thus significantly increased the prediction of psychosocial functioning of primary care patients. These findings further support the use of the DCPR-R in PC settings, particularly in patients who do not satisfy DSM-5 criteria and yet present with high psychological distress, maladaptive illness behavior, impaired psychological well-being and quality of life.

Criterion-related validity in a sample of migraine outpatients: the diagnostic criteria for psychosomatic research

OBJECTIVE

The Diagnostic Criteria for Psychosomatic Research (DCPR) are those of psychosomatic syndromes that did not find room in the classical taxonomy. More recently, the DCPR were updated, called DCPR-revised (DCPR-R). The present study was conducted to test the criterion-related validity of the DCPR-R.

METHODS

Two hundred consecutive subjects were enrolled at the Headache Center of Careggi University Hospital (Italy): 100 subjects had a diagnosis of chronic migraine (CM) and 100 had a diagnosis of episodic migraine (EM). Participants received a clinical assessment, which included the DCPR-revised Semi-Structured Interview (DCPR-R SSI), the Structured Clinical Interview for DSM-5 (SCID-5), and the psychosocial index (PSI).

RESULTS

Forty-seven subjects (23.5%) had at least one DSM-5 diagnosis: major depressive disorder (8.5%; n = 17) and agoraphobia (7.5%; n = 15) were the most frequent. One hundred and ten subjects (55%) reported a DCPR-R diagnosis: allostatic overload (29%; n = 58) and type A behavior (10.5%; n = 21) were the most frequent. When the incremental validity of the DCPR system over the DSM system was tested using PSI subscales as the criterion variable, the DCPR-R increased up to 0.11-0.24 the amount of explained variance. Subjects with at least one DCPR-R diagnosis showed lower PSI well-being scores (p = .001), higher PSI stress scores (p < .001), and higher PSI psychological distress scores (p = .008) than subjects without a DCPR-R diagnosis.

CONCLUSION

The DCPR-R showed a good criterion-related validity in migraine outpatients. Thus, they might be implemented, together with the DSM-5, in the assessment of migraine subjects.

The Use of Demoralization Scale in Italian Kidney Transplant Recipients

Demoralization is a commonly observed syndrome in medically ill patients. The risk of demoralization may increase in patients after a kidney transplant (KTRs) because of the stressful nature of renal transplantation, psychosocial challenges, and adjustment needs. No study is available on demoralization amongst KTRs. The purpose of our study was to evaluate the validity of the Italian version of the Demoralization Scale (DS-IT) and the prevalence of demoralization in KTRs. Also, we aimed at exploring the association of the DS-IT with International Classification of Diseases (ICD) psychiatric diagnoses, post-traumatic growth (PTG), psychological and physical symptoms, and daily-life problems. A total of 134 KTRs were administered the MINI International Neuropsychiatric Interview 6.0. and the Diagnostic Criteria for Psychosomatic Research-Demoralization (DCPR/D) Interview. The DS-IT, the Edmonton Symptom Assessment System (ESAS), the Canadian Problem Checklist (CPC), were used to measure demoralization, physical and psychological symptoms, and daily-life problems; also, positive psychological experience of kidney transplantation was assessed with the PTG Inventory. Routine biochemistry and sociodemographic data were collected. Exploratory factor analysis demonstrated a four-dimensional factor structure of the DS-IT, explaining 55% of the variance (loss of meaning and purpose, disheartenment, dysphoria, and sense of failure). DS-IT Cronbach alpha coefficients indicated good or acceptable level of internal consistency. The area under the Receiving Operating Characteristics (ROC) curve for DS-IT (against the DCPR/D interview as a gold standard) was 0.92. The DS-IT optimal cut-off points were ≥20 (sensitivity 0.87, specificity 0.82). By examining the level of demoralization, 14.2%, 46.3%, 24.6%, and 14.6% of our sample were classified as having no, low, moderate, and high demoralization, respectively, with differences according to the ICD psychiatric diagnoses (p < 0.001). DS-IT Total and subscales scores were positively correlated with scores of ESAS symptoms and CPC score. A correlation between DS-IT loss of meaning and purpose subscale and PTGI appreciation of life subscale (p < 0.05) was found. This study shows, for the first time, a satisfactory level of reliability of the DS-IT and a high prevalence of severe demoralization in KTRs.

Screening Performance of Edmonton Symptom Assessment System in Kidney Transplant Recipients

An average prevalence of 35% for psychiatric comorbidity has been reported in kidney transplant recipients (KTRs) and an even higher prevalence of other psychosocial syndromes, as defined by the Diagnostic Criteria for Psychosomatic Research (DCPR), has also been found in this population. Consequently, an easy, simple, rapid psychiatric tool is needed to measure physical and psychological symptoms of distress in KTRs. Recently, the Edmonton Symptom Assessment System (ESAS), a pragmatic patient-centred symptom assessment tool, was validated in a single cohort of KTRs. The aims of this study were: to test the screening performances of ESAS for the International Classification of Diseases-10th Revision (ICD-10) psychiatric diagnoses in KTRs; to investigate the optimal cut-off points for ESAS physical, psychological and global subscales in detecting ICD-10 psychiatric diagnoses; and to compare ESAS scores among KTR with ICD-10 diagnosis and DCPR diagnosis. 134 KTRs were evaluated and administered the MINI International Neuropsychiatric Interview 6.0 and the DCPR Interview. The ESAS and Canadian Problem Checklist (CPC) were given as self-report instruments to be filled in and were used to examine the severity of physical and psychological symptoms and daily-life problems. The physical distress sub-score (ESAS-PHYS), psychological distress sub-score (ESAS-PSY) and global distress score (ESAS-TOT) were obtained by summing up scores of six physical symptoms, four psychological symptoms and all single ESAS symptoms, respectively. Routine biochemistry, immunosuppressive agents, socio-demographic and clinical data were collected. Receiving Operating Characteristic (ROC) analysis was used to examine the ability of the ESAS emotional distress (DT) item, ESAS-TOT, ESAS-PSY and ESAS-PHYS, to detect psychiatric cases defined by using MINI6.0. The area under the ROC curve for ESAS-TOT, ESAS-PHYS, ESAS-PSY and DT item were 0.85, 0.73, 0.89, and 0.77, respectively. The DT item, ESAS-TOT and ESAS-PSY optimal cut-off points were ≥4 (sensitivity 0.74, specificity 0.73), ≥20 (sensitivity 0.85, specificity 0.74) and ≥12 (sensitivity 0.85, specificity 0.80), respectively. No valid ESAS-PHYS cut-off was found (sensitivity <0.7, specificity <0.7). Thirty-nine (84.8%) KTRs with ICD-10 diagnosis did exceed both ESAS-TOT and ESAS-PSY cut-offs. Higher scores on the ESAS symptoms (except shortness of breath and lack of appetite) and on the CPC problems were found for ICD-10 cases and DCRP cases than for ICD-10 no-cases and DCPR no-cases. This study shows that ESAS had an optimal screening performance (84.8%) to identify ICD-10 psychiatric diagnosis, evaluated with MINI; furthermore, ESAS-TOT and ESAS-PSY cut-off points could provide a guide for clinical symptom management in KTRs.

Assessing demoralization in medically ill patients: Factor structure of the Italian version of the demoralization scale and development of short versions with the item response theory framework

OBJECTIVE

Demoralization has been mostly investigated in oncology but is also relevant for patients with other physical illnesses. Our aims were to investigate the psychometric properties of the 24-item Italian version of the Demoralization Scale (DS-24) among medically ill inpatients, and to develop shorter versions for screening.

METHODS

Four-hundred and seventy-three participants were recruited from medical wards of the University Hospital of Ferrara. Patients were assessed using the Diagnostic Criteria for Psychosomatic Research-Demoralization module (DCPR/D), Demoralization Scale (DS-24), Patient Health Questionnaire-9 (PHQ-9), Brief-Symptom Inventory-18, Anxiety subscale (BSI-Anx) and EuroQol Group (EQ-5D). Confirmatory factor analyses of previous structures and exploratory factor analyses were conducted using an Item Response Theory approach, including a bifactor model.

RESULTS

According to DCPR/D criteria, the prevalence of demoralization was 40%. Confirmatory analyses revealed that none out of seven factor structures from oncology studies adequately fitted data from hospital inpatients. Exploratory Item Factor Analysis uncovered a four-factor model comprising Disheartenment, Dysphoria, Sense of Failure, Loss of Meaning and Purpose, or a bifactor model, comprising similar factors with the addition of a general factor accounting for 45% of the variance. Moreover, we developed 13 and 6-item versions of the DS, both retaining high correlation with DS-24 scores (r = 0.98 and r = 0.95, respectively) and concordance with DCPR/D criteria (AUC-ROC 0.82 and 0.81).

CONCLUSION

The DS factor structure differs between general hospital and cancer patients. Differences may depend on intrinsic disease features and cultural-geographic factors. The short versions of the DS-24 may aid clinicians in identifying demoralized patients in hospital settings.

A Trial Integrating Different Methods to Assess Psychosocial Problems in Primary Care

BACKGROUND

A number of studies have documented psychosocial problems, psychiatric morbidity and impaired quality of life in primary care patients.

OBJECTIVE

The aim of this trial was to test the usefulness of the joint use of different diagnostic interviews and self-rated questionnaires.

METHODS

Two hundred consecutive patients in a primary care practice in Italy underwent the Structured Clinical Interview for DSM-5 and the Semi-Structured Interview for the Diagnostic Criteria for Psychosomatic Research (DCPR) in its recently revised form. As self-rated evaluations, the PsychoSocial Index, the Short-Form Health Survey and the Illness Attitude Scales were administered.

RESULTS

There were 46 patients (23%) with at least 1 DSM-5 diagnosis. Eighty-eight patients (44%) had at least 1 DCPR diagnosis, mainly maladaptive illness behavior (26.5%), allostatic overload (15.5%) and demoralization (15%). There were 47 (23.5%) patients who had a DCPR diagnosis only; 5 subjects (2.5%) had a DSM diagnosis only. Patients with DCPR syndromes displayed significantly higher self-rated levels of stress, psychological distress and maladaptive illness behavior and significantly lower levels of quality of life and well-being than patients with no diagnoses.

CONCLUSIONS

In a busy clinical setting, a simple self-rated questionnaire such as the PsychoSocial Index may afford a useful tool to unveil patient current distress. The DCPR can provide clinical information for a substantial number of patients who do not satisfy DSM-5 classification criteria and yet present with psychosocial problems, as measured by self-rated scales. The DCPR may improve the assessment and treatment plan of primary care psychologists or consulting psychiatrists.
