Patients with unexplained physical symptoms have poorer quality of life and higher costs than other patient groups: a cross-sectional study on burden

Optimism, Resilience, and General Self-Efficacy Predict Lower Somatic Burden during the COVID-19 Pandemic

There is scarce evidence of a relationship between positive and psychosomatic characteristics. This study aimed to examine the associations of somatic burden with psychological resources such as optimism, resilience, and general self-efficacy. Russian participants (n = 1020) completed measures of psychological resources at Time 1 and somatic symptoms at Time 2. The results showed that somatic burden decreased with greater levels of optimism, resilience, and general self-efficacy. Regarding health and sociodemographic characteristics, female sex increased somatic burden in the model with optimism scores, university education decreased somatic burden in the model with resilience scores, and history of COVID-19 disease increased somatic burden in the models with optimism, resilience, and general self-efficacy scores. This study has theoretical and practical contributions. It combines positive psychology and psychosomatic medicine and highlights the value of psychological resource interventions in the treatment and prevention of somatic burden. These findings may be useful for scientists, clinicians, and practitioners.

Physician perceptions of medically unexplained symptoms in adolescent patients presenting to the emergency department

INTRODUCTION

Adolescents presenting with medically unexplained symptoms (MUS) in non-mental healthcare settings, particularly Emergency Departments (EDs), pose diagnostic challenges necessitating a comprehensive bio-psycho-social approach. Amid the youth mental health crisis, recognising psychological distress is imperative. This study delved into physicians' perceptions and diagnostic tendencies regarding such cases, exploring the potential overshadowing of psychosomatic presentations by medicalized diagnoses in EDs.

METHODS

Our study involved 74 physicians, representing 82% of eligible respondents in the Paediatric Emergency Medicine Department, and was conducted using an online questionnaire examining perceptions of case scenarios with psychosomatic presentations.

RESULTS

Results disclosed a prevalent inclination toward medical diagnoses, with less than 10% of physicians considering psychosomatic conditions in specific scenarios. Interestingly, psychosomatic diagnoses were more probable for symptoms like headaches, shortness of breath, and chest pain. The study uncovered a possible bias among physicians towards medical diagnoses in EDs for adolescents with MUS, possibly stemming from physicians' focus on physical care, diagnostic uncertainties, cognitive biases, and concerns about stigmatisation.

CONCLUSION

Adolescents with MUS seeking assistance in non-mental health settings may encounter delayed mental health diagnoses and interventions. Psychosomatic symptoms could signify stressors or underlying mental health disorders. Recognising psychosocial distress early on is crucial for optimal mental health outcomes. Consequently, the study advocates for a paradigm shift towards a holistic bio-psychosocial approach in both medical education and practice.

The role of fatigue in patients with complex regional pain syndrome

BACKGROUND AND PURPOSE

Fatigue affects patients across a variety of neurological diseases, including chronic pain syndromes such as complex regional pain syndrome (CRPS). In CRPS, fatigue is often underestimated, as the focus lies in the assessment and managing of pain and sensorimotor deficits. This study aimed to investigate the prevalence, characteristics, and influence of fatigue on CRPS severity and quality of life in these patients. Such insights could enhance the clinical management of this challenging condition.

METHODS

In this prospective study, 181 CRPS patients and 141 age and gender-matched individuals with injury but without chronic pain were interviewed using the Fatigue Scale for Motor and Cognitive Function to assess fatigue. Depressive symptoms and quality of life (QoL) were also evaluated as additional outcome measures. Statistical analysis was performed to examine differences in fatigue prevalence between the groups, as well as associations with CRPS severity, pain levels, and clinical phenotype. In addition, best subsets regression was used to identify the primary factors influencing QoL. Fatigue was tested in a mediation analysis as a mediator between pain and depression.

RESULTS

CRPS patients showed significantly higher fatigue levels compared to controls (CRPS: 75 [IQR: 57-85] vs. controls: 39 [IQR: 25-57]). Based on the FSMC, 44.2% in the control group experienced fatigue, while 85% of patients with CRPS experienced fatigue (p < 0.001), of which 6% were mild, 15% moderate, and 67% severe. In CRPS severe fatigue was associated with higher pain intensities compared to no fatigue (pain at rest: p = 0.003; pain during movement: p = 0.007) or moderate fatigue (pain during movement: p = 0.03). QoL in our cohort was mainly influenced by pain (pain during movement: adj.R2 = 0.38; p < 0.001, pain at rest: Δadj.R2 = 0.02, p = 0.007) and depressive symptoms (Δadj.R2 = 0.12, p < 0.001). Subsequent analyses indicated that pain and depressive symptoms primarily impact QoL in CPRS whereas fatigue may exert an indirect influence by mediating the connection between pain and depression (p < 0.001).

CONCLUSIONS

This pioneering study investigates the prevalence of fatigue in CRPS patients and its relation to disease characteristics. Our results indicate a high prevalence of severe fatigue, strongly correlated with pain intensity, and its importance in the interaction between pain and depression in CRPS. These findings underscore the significant role of fatigue as a disease factor in CRPS. Therefore, the evaluation of CRPS-related disability should include a standardized assessment of fatigue for comprehensive clinical management.

The burden of persistent symptom diagnoses in primary care patients: a cross-sectional study

INTRODUCTION

The burden of symptoms is a subjective experience of distress. Little is known on the burden of feeling unwell in patients with persistent symptom diagnoses. The aim of this study was to assess the burden in primary care patients with persistent symptom diagnoses compared to other primary care patients.

METHODS

A cross-sectional study was performed in which an online survey was sent to random samples of 889 patients with persistent symptom diagnoses (>1 year) and 443 other primary care patients after a transactional identification in a Dutch primary care data registry. Validated questionnaires were used to assess the severity of symptoms (PHQ-15), Symptom Intensity and Symptom Interference questionnaires, depression (PHQ-9), anxiety (GAD-7), quality of life (SF-12 and EQ-5D-5L)) and social functioning (SPF-ILs).

RESULTS

Overall, 243 patients completed the survey: 178 (73.3%) patients in the persistent symptom diagnoses group and 65 (26.7%) patients in the control group. In the persistent group, 65 (36.5%) patients did not have persistent symptom(s) anymore according to the survey response. Patients who still had persistent symptom diagnoses (n = 113, 63.5%) reported significantly more severe somatic symptoms (mean difference = 3.6, [95% CI: 0.24, 4.41]), depression (mean difference = 3.0 [95% CI: 1.24, 3.61]) and anxiety (mean difference = 2.3 [95% CI: 0.28, 3.10]) and significantly lower physical functioning (mean difference = - 6.8 [95% CI: -8.96, -3.92]).

CONCLUSION

Patients with persistent symptom diagnoses suffer from high levels of symptoms burden. The burden in patient with persistent symptoms should not be underestimated as awareness of this burden may enhance person-centered care.

Public and patient involvement in the development of an internet-based guide for persistent somatic symptoms (GUIDE.PSS): A qualitative study on the needs of those affected

BACKGROUND

Persistent somatic symptoms (PSS) frequently remain under-treated in health care settings. Evidence-based services that lead affected individuals to early guideline-based care are currently missing. This study aimed to identify the needs of those affected concerning an internet-based guide. The second aim was to evaluate public and patient involvement (PPI).

METHODS

Participants experiencing PSS for at least 6 months were recruited via hospitals, psychotherapeutic practices and self-help organizations. Qualitative data were gathered via ideation discussions and prioritization tasks. Thematic analysis was conducted to gain insight on the needs of people with lived experiences. PPI was quantitatively evaluated with the Public and Patient Engagement Evaluation Tool.

RESULTS

A total of 12 individuals participated (eight females, ages 22-66 years, duration of symptoms 1-43 years). Participants wanted to feel more supported, validated, in control and engaged with managing their health. Content-related preferences included education, self-help, social support and contact addresses. The majority of participants (>90%) experienced their involvement as worthwhile.

CONCLUSIONS

To the best of our knowledge, this is one of the first studies describing PPI in intervention development for PSS. The involvement was perceived as a valuable contribution to the development process.

PATIENT OR PUBLIC CONTRIBUTION

Adults with lived experiences were involved at the level of collaboration through the establishment of a participatory research team (PRT) and at the level of consultation through a workshop series, including one of the coauthors. They were involved in developing and validating intervention material and checking data interpretation.

Emotion dynamics and somatic symptoms in everyday life: Ecological momentary assessment in somatic symptom disorder and healthy controls

OBJECTIVE

Negative affectivity (NA) is associated with the emergence and persistence of physical symptoms with unclear organic pathology. This study investigated the temporal dynamics of NA and somatic symptom burden using ecological momentary assessment (EMA) in adults with somatic symptom disorder (SSD) and healthy control participants (HC).

METHODS

Participants underwent a seven-day, smartphone-based EMA, with 6 randomly-stratified time points per day. NA was assessed using a five-item short form of the Positive and Negative Affectivity Scale (PANAS) and somatic symptom burden with two self-constructed items. 22 persons with SSD and 20 HCs were included in multilevel analyses.

RESULTS

Within-person analyses showed a significantly stronger (positive) association of concurrent NA with somatic symptom burden in participants with SSD than in HCs, β = 0.15, SE = 0.04, p = .001. Time-lagged analyses demonstrated that, across groups, NA at a previous time point t-1 significantly predicted somatic symptom burden at the subsequent timepoint t, β = 0.09, SE = 0.03, p = .005, but not in the other direction (somatic symptom burdent-1→ NAt, β = 0.01, SE = 0.04, p = .79). Between-person analyses showed that both inertia (i.e., persistence of negative affective states), d = 0.74, and instability (i.e., magnitude of moment-to-moment fluctuations), d = 0.76 of NA were significantly higher in participants with SSD than in HCs.

CONCLUSIONS

Our findings sustain the idea of (negative) affect-driven modulation in somatic signal processing and suggest that interoceptive and emotional differentiation training can advance the psychotherapeutic treatment of SSD.

Somatic symptoms in schizophrenia: Association with socio-demographic and clinical characteristics, disability and quality of life

Background and Aims

There is lack of research on somatic symptoms in schizophrenia. We aimed at finding prevalence and types of somatic symptoms in patients with schizophrenia and assessed their association with socio-demographic and clinical characteristics.

Methods

We assessed somatic symptoms using Patient Health Questionnaire-15 (PHQ-15) in 93 patients with schizophrenia diagnosed on ICD10-DCR. Scale for Assessment of Positive Symptoms and Scale for Assessment of Negative Symptoms, WHO Disability Assessment Schedule 2.0, WHO Quality of Life (BREF) Hindi version and Liverpool University Neuroleptic Side-Effect Rating Scale were used to assess psychopathology, disability, quality of life and side effects.

Results

Significant somatic symptoms (n ≥5 on PHQ-15) were present in 62 (67.7%) patients with schizophrenia. Forty three (69.4%) had mild (n = 5-9 on PHQ-15), 17 (27.4%) had moderate (n = 10-14 on PHQ-15), and only 2 (3.2%) had severe (n = ≥15 on PHQ -15) somatic symptoms. Mean somatic symptoms score on PHQ-15 was 7.28 (± 3.83); 96.8% reported feeling tired, 76.3% had constipation or diarrhoea, 67.7% trouble in sleeping, 61.3% nausea or indigestion, 52.7% back pain and 51.6% headache. Patients with somatic symptoms were older in age, had longer duration of illness and treatment, and had more negative symptoms. They had higher disability and poor quality of life especially in physical domain.

Conclusion

Somatic symptoms are common in patients with schizophrenia and are associated with chronicity, refractoriness and negative symptoms, significant disability and poor quality of life. Thus during routine clinical practice, somatic symptoms should be assessed and managed in these patients.

The cost-effectiveness of an indicated blended care intervention in primary care compared to usual care in patients with moderate persistent somatic symptoms

INTRODUCTION

Appropriate treatment for people with an increased risk for developing chronic Persistent Somatic Symptoms (PSS) is of great importance at an early stage to improve quality of life and prevent high costs for society.

OBJECTIVE

To evaluate the cost-effectiveness of an integrated blended care intervention compared to usual care for QALYs, subjective symptom impact and physical and mental health status in patients with moderate PSS.

METHODS

This economic evaluation was conducted alongside a 12-month prospective, multicenter cluster randomized controlled trial in Dutch primary care. 80 participants received the intervention and 80 participants received usual care. Seemingly unrelated regression analyzes were performed to estimate cost and effect differences. Missing data were imputed using multiple imputation. Bootstrapping techniques were used to estimate uncertainty.

RESULTS

We found no significant difference in total societal costs. Intervention, primary and secondary healthcare and absenteeism costs were higher for the intervention group. The ICER for QALYs demonstrated the intervention was on average less costly and less effective compared to usual care. For the subjective symptom impact and physical health, the ICER indicated that the intervention group was on average less costly and more effective. For mental health, the intervention was on average more costly and less effective.

CONCLUSION

We didn't find an integrated blended primary care intervention to be cost-effective compared to usual care. However, when looking on relevant, but specific outcome measures (subjective symptom impact and physical health) for this population, average costs are found to be lower and the effectiveness found to be higher.

Early identification of persistent somatic symptoms in primary care: data-driven and theory-driven predictive modelling based on electronic medical records of Dutch general practices

OBJECTIVE

The present study aimed to early identify patients with persistent somatic symptoms (PSS) in primary care by exploring routine care data-based approaches.

DESIGN/SETTING

A cohort study based on routine primary care data from 76 general practices in the Netherlands was executed for predictive modelling.

PARTICIPANTS

Inclusion of 94 440 adult patients was based on: at least 7-year general practice enrolment, having more than one symptom/disease registration and >10 consultations.

METHODS

Cases were selected based on the first PSS registration in 2017-2018. Candidate predictors were selected 2-5 years prior to PSS and categorised into data-driven approaches: symptoms/diseases, medications, referrals, sequential patterns and changing lab results; and theory-driven approaches: constructed factors based on literature and terminology in free text. Of these, 12 candidate predictor categories were formed and used to develop prediction models by cross-validated least absolute shrinkage and selection operator regression on 80% of the dataset. Derived models were internally validated on the remaining 20% of the dataset.

RESULTS

All models had comparable predictive values (area under the receiver operating characteristic curves=0.70 to 0.72). Predictors are related to genital complaints, specific symptoms (eg, digestive, fatigue and mood), healthcare utilisation, and number of complaints. Most fruitful predictor categories are literature-based and medications. Predictors often had overlapping constructs, such as digestive symptoms (symptom/disease codes) and drugs for anti-constipation (medication codes), indicating that registration is inconsistent between general practitioners (GPs).

CONCLUSIONS

The findings indicate low to moderate diagnostic accuracy for early identification of PSS based on routine primary care data. Nonetheless, simple clinical decision rules based on structured symptom/disease or medication codes could possibly be an efficient way to support GPs in identifying patients at risk of PSS. A full data-based prediction currently appears to be hampered by inconsistent and missing registrations. Future research on predictive modelling of PSS using routine care data should focus on data enrichment or free-text mining to overcome inconsistent registrations and improve predictive accuracy.

Loneliness in patients with somatic symptom disorder

OBJECTIVES

Patients with somatoform disorders often experience loneliness. They feel misunderstood and socially rejected. Whereas loneliness is related to several medical conditions, social support can minimize loneliness. In the current study, differences in loneliness and the evaluation of social support between patients with Somatic Symptom Disorder (SSD) and healthy controls were investigated using standardized questionnaires. In addition, the relation between loneliness and somatic symptoms was investigated.

METHODS

In a cross-sectional study design, a group of patients with SSD (n=75) was compared to a healthy control group (n=112). It was hypothesized that [1] patients with SSD experience more loneliness and evaluate their social support more negatively than healthy controls and [2] loneliness will correlate positively with experienced somatic symptoms.

RESULTS

In comparison to healthy controls, patients with SSD experienced more loneliness and their evaluation of social support was more negative. In addition, loneliness correlated positively with the degree of experienced somatic symptoms.

CONCLUSIONS

Patients with SSD experienced lower social support, more loneliness, and across the two groups loneliness was positively associated with somatic symptoms. Effect sizes were all large. Therefore, these results may have implications for the treatment of SSD.

Work productivity (absenteeism and presenteeism) in persons with common mental disorders: An observational study from South India

Background

The greatest contributor to the economic impact of common mental disorders (CMDs) is said to be the loss of work productivity. There is a paucity of studies from India that looks at the impact of CMDs on the productivity of work, which costs both patient and society significantly.

Aim

To assess and compare work productivity by evaluating both absolute and relative presenteeism and absenteeism, in persons with CMDs.

Materials and Methods

This was a cross-sectional observational study on 220 subjects (110, 58, and 52 patients with depressive disorder, anxiety disorders, and somatoform disorders, respectively), recruited through purposive sampling. We evaluated work productivity using the World Health Organization Health and Work Performance Questionnaire.

Results

Absolute absenteeism was significantly different before and after treatment for CMDs as a group but not for individual disorders. Relative absenteeism, absolute presenteeism, and relative presenteeism were all significantly different before and after treatment among both CMDs as a group and also among individual disorders. Both presenteeism and absenteeism (absolute as well as relative) did not differ significantly across the diagnostic groups. Work productivity has been linearly associated with illness severity and disability.

Conclusion

CMDs are associated with a significant loss of work productivity. Presenteeism is costlier than absenteeism in affecting work productivity. Loss of work productivity appears to be transdiagnostic across all CMDs. Also, the severity of loss of work productivity is associated linearly with the severity of illness and disability.

Association between Negative Life Events and Somatic Symptoms: A Mediation Model through Self-Esteem and Depression

The purpose of this study was to investigate the serial multiple mediation of self-esteem and depression in the relationship between negative life events and somatic symptoms in Chinese medical students. We recruited a total of 3383 medical students for this study, and used the Patient Health Questionnaire-15 to assess the somatic symptoms of subjects; the Adolescent Self-Rating Life Events Check List to assess negative life events; the Rosenberg Self-Esteem Scale to assess self-esteem; and the Patient Health Questionnaire for depression. Descriptive analysis and statistical tests were then performed on the collected data. We showed that 39.17% of the medical students had mild somatic symptoms, 24.14% had moderate somatic symptoms, and 5.66% had severe somatic symptoms; we observed significant differences in somatic symptoms among genders, living expenses, and one-child. For negative life events, interpersonal stress was the most important predictor of somatization during the regression analysis. In addition, we observed significance for both the direct and part of the indirect paths from negative life events to somatic symptoms using mediation model analysis. However, we noted that there was no significance for the path through negative life events and self-esteem to somatic symptoms. This study revealed a high prevalence of somatic symptoms among Chinese medical students, and the findings suggested that interventions aimed at reducing somatization in this population should consider the impact of negative life events, particularly those related to interpersonal stress. One potential approach to mitigating the effects of negative life events on somatization is to enhance self-esteem and decrease the level of depression among medical students.

Somatic symptoms and related disorders in a large cohort of people with epilepsy: A cohort study

OBJECTIVE

This study was undertaken to characterize somatic symptoms and related disorders (SSD) in epilepsy.

METHODS

Adults with epilepsy under active follow-up at a tertiary epilepsy center were consecutively enrolled. The diagnosis of SSD was performed by an experienced psychologist based on the structured clinical interview for Statistical Manual of Mental Disorders, 5th edition. Detailed social/demographic data, epilepsy features, psychiatric features, life quality, disability, and economic burden were collected and compared between people with SSD and those without. Bodily distress syndrome checklist, Somatic Symptom Disorder-B Criteria Scale, Patient Health Questionnaire-9, and Generalized Anxiety Disorder seven-item scale (GAD-7) were used to evaluate SSD individuals' somatic symptoms, symptom-related psychological distress, and depressive and anxious symptoms. Quality of life and disability were assessed by Quality of Life in Epilepsy Inventory 31 (QOLIE-31) and World Health Organization Disability Assessment Schedule V.2.0 (WHO DAS 2.0). A risk prediction nomogram was generated using least absolute shrinkage and selection operator (LASSO) analysis and validated.

RESULTS

One hundred fifty of 631 participants (24%) were diagnosed with SSD. In people with SSD, the top three most common somatic symptoms were memory impairment, headache, and dizziness (85%, 80%, and 78%, respectively), and multiple systems were involved in most (82%) people with SSD. Compared with people without SSD, those with SSD had lower QOLIE-31 total scores, and higher WHO DAS 2.0 scores and disease economic burdens. LASSO analysis suggested that a history of severe traumatic brain injury, hippocampal sclerosis, low seizure worry and medication effects scores on QOLIE-31, multiple systems affected by somatic symptoms, and a high GAD-7 score were risk factors of SSD. The nomogram was validated for good accuracy in the training and testing cohorts.

SIGNIFICANCE

SSD are likely to be a common comorbidity in epilepsy and harm epilepsy prognosis. Our risk prediction nomogram was successfully developed but needs further validation in larger cohorts.

Prevalence of medically unexplained symptoms in adults who are high users of healthcare services and magnitude of associated costs: a systematic review

INTRODUCTION

Medically unexplained symptoms (MUS) is a common clinical syndrome in primary and secondary healthcare service. Outcomes for patients with persistent MUS include increased disability, poorer quality of life and higher healthcare costs. The aim of this systematic review was to determine the prevalence of MUS in patients who are high users of healthcare or high-cost patients in comparison with routine users and the magnitude of associated costs.

DESIGN

A systematic review of the available literature.

DATA SOURCES AND ELIGIBILITY CRITERIA

The following electronic databases were systematically searched without language restriction from inception to June 2018 and updated on 22 October 2021: MEDLINE, PsycINFO, EMBASE, CINAHL and PROSPERO. Inclusion criteria included studies investigating adults aged ≥18 years, who were high healthcare users or accrued high healthcare costs, in which the prevalence and/or associated costs of MUS was quantified. Two reviewers independently extracted information on study characteristics, exposure and outcomes.

RESULTS

From 5622 identified publications, 25 studies from 9 countries involving 31 650 patients were selected for inclusion. Due to high risk of bias in many studies and heterogeneity between studies, results are described narratively. There were wide variations in prevalence estimates for MUS in high users of healthcare (2.9%-76%), but MUS was more prevalent in high use groups compared with low use groups in all but one of the 12 studies that included a comparator group. Only three studies investigated healthcare costs associated with MUS, and all three reported greater healthcare costs associated with MUS.

CONCLUSION

MUS has been found to be more prevalent in high use healthcare populations than comparator groups, but the magnitude of difference is difficult to estimate due to considerable heterogeneity between studies and potential for bias. Future studies should prioritise a standardised approach to this research area, with agreed definitions of MUS and high healthcare use.

Discovering strengths in patients with medically unexplained symptoms - a focus group study with general practitioners

BACKGROUND

When patients suffer medically unexplained symptoms, consultations can be difficult and frustrating for both patient and GP. Acknowledging the patient as a co-subject can be particularly important when the symptoms remain unexplained. One way of seeing the patient as a co-subject is by recognizing any among their strong sides.

OBJECTIVES

To explore GPs' experiences with discovering strengths in their patients with medically unexplained symptoms and elicit GPs' reflections on how this might be useful.

METHODS

Four focus-groups with 17 GPs in Norway. Verbatim transcripts from the interviews were analyzed by systematic text condensation.

RESULTS

Recollecting patients' strengths was quiet challenging to the GPs. Gradually they nevertheless shared a range of examples, and many participants had experienced that knowing patients' strong sides could make consultations less demanding, and sometimes enable the GP to provide better help. Identifying strengths in patients with unexplained symptoms required a deliberate effort on the GPs' behalf, and this seemed to be a result of a strong focus on biomedical disease and loss of function.

CONCLUSIONS

Acknowledging patients' strong sides can bolster GPs' ability to help patients with medically unexplained symptoms. However, the epistemic disadvantage of generalist expertise makes this hard to achieve. It is difficult for GPs to integrate person-centered perspectives with biomedical knowledge due to the privileged position of the latter. This seems to indicate a need for system-level innovations to increase the status of person-centered clinical work. Key pointsMUS is challenging for both patients and GPs mainly because of the incongruence between symptoms and the dominating biomedical model.GPs' focus on pathology and loss of function can prevent them from discovering patients' strengths.Awareness of patients' strengths can make consultations less demanding for GPs and enable them to provide better help.A conscious effort is needed to discover patients' strengths.

Experiences of general practitioners explaining central sensitisation to patients with persistent physical symptoms: a focus group study

OBJECTIVE

Patients with persistent physical symptoms (PPS) require an explanation that is acceptable and comprehensible to them. Central sensitisation (CS) is an explanatory model for PPS and chronic pain that has been broadly applied in the context of pain medicine, but, until recently, not by general practitioners (GPs). We explored how GPs used the CS model in their consultations with patients with PPS.

DESIGN AND SETTING

A qualitative focus group study among GPs in the Netherlands.

METHODS

We instructed 33 GPs on how to explain CS to patients with PPS. After 0.5-1.5 years of using the CS model, 26 GPs participated in focus groups and interviews to report and discuss their experiences with CS as an explanatory model. Audio recordings were transcribed and two researchers independently analysed the data. The text was coded, codes were organised into themes and discussed until consensus was reached.

RESULTS

We identified eleven themes and grouped these into four categories.The GPs regarded the CS model as evidence-based, credible and giving recognition to the patient. On the other hand, they found explaining the CS model difficult and time-consuming. They tailored the CS model to their patients' needs and used multiple consultations to explain the model. The GPs reported that the use of the CS model seemed to improve the understanding and acceptance of the symptoms by the patients and seemed to reduce their need for more diagnostic tests. Furthermore, patients seemed to become more motivated to accept appropriate therapy.

CONCLUSION

GPs reported that they were able to provide explanations with the CS model to their patients with PPS. They regarded the model as evidence-based, credible and giving recognition to the patient, but explaining it difficult and time-consuming.

Validity and responsiveness of GHC-index in patients with amalgam-attributed health complaints

OBJECTIVE

Many patients have medically unexplained physical symptoms (MUPS); some of them attribute their health complaints to dental amalgam fillings. The aim of this study was to assess the validity and responsiveness of General Health Complaints index (GHC-index) for measuring the symptom load in MUPS patients compared to the widely used symptom outcome measure, Giessen Subjective Complaints List (GBB-24).

METHODS

Three outcome measures - GHC-index, GBB-24, and Munich Amalgam Scale (MAS) - were administered at baseline and 12 months after removal of all dental amalgam restorations. The validity and responsiveness of these symptom measures were tested against external anchors: bodily distress syndrome (BDS), SF-36 vitality, and visual analogue scale (VAS). We tested both convergent and known group validities. We also examined the predictive validity and responsiveness to changes for each instrument.

RESULTS

All the main outcome measures showed evidence of convergent and known group validities. The GHC-index, GBB-24 and MAS were all able to detect the anticipated differences in BDS and Energy. But the GBB-24 was more efficient in discriminating the BDS compared with the GHC-index (relative efficiency: RE = 0.69; 95% CI: 0.41-0.96) and MAS (RE = 0.59; 95% CI: 0.32-0.86). Each main outcome variable revealed good predictive validity for vitality (standardized coefficient: b ≈ 0.71 and R² ≈ 0.50). Moderate to high sensitivity to change over time was demonstrated, with GHC-index performing better.

CONCLUSION

The GHC-index is a valid and responsive instrument for assessing symptom load in MUPS patients attributing their health complaints to amalgam fillings and undergoing amalgam removal.

Barriers and facilitators to implementing interventions for medically unexplained symptoms in primary and secondary care: A systematic review

OBJECTIVE

To integrate existing literature on barriers and facilitators to implementing interventions for Medically Unexplained Symptoms (MUS) in primary and secondary care.

METHOD

Systematic review following PRISMA guidelines. A search of PsychINFO/Pubmed/Web of Science was performed to select studies focusing on MUS-interventions and implementation. All included papers were checked for quality and bias. A narrative synthesis approach was used to describe the included papers by implementation level, ranging from the specific intervention to the broader economic/political context.

RESULTS

20 (quantitative/qualitative/mixed design) papers were included, but the quantitative studies especially, lacked methodological quality, with possible publication bias as a result. Results showed that the intervention needs to be acceptable and in line with daily practice routines. The professional's attitude and skills are important for implementation success, as well as for overcoming problems in the professional-patient interaction. If patients stick to finding a somatic cause, this hampers implementation. A lack of time is a frequently mentioned barrier at the organizational level. Barriers/facilitators at the social context level and at the economic/political level were barely reported on in the included papers.

CONCLUSION

Results were integrated into an existing implementation model, as an example of how MUS-interventions can be successfully implemented in practice.

Tests for central sensitization in general practice: a Delphi study

INTRODUCTION

Central sensitization (CS) may explain the persistence of symptoms in patients with chronic pain and persistent physical symptoms (PPS). There is a need for assessing CS in the consultation room. In a recently published systematic review, we made an inventory of tests for CS. In this study we aimed to assess which tests might have added value, might be feasible and thus be suitable for use in general practice.

METHODS

We conducted a Delphi study consisting of two e-mail rounds to reach consensus among experts in chronic pain and PPS. We invited 40 national and international experts on chronic pain and PPS, 27 agreed to participate. We selected 12 tests from our systematic review and additional searches; panellists added three more tests in the first round. We asked the panellists, both clinicians and researchers, to rate these 15 tests on technical feasibility for use in general practice, added value and to provide an overall judgement for suitability in general practice.

RESULTS

In two rounds the panellists reached consensus on 14 of the 15 tests: three were included, eleven excluded. Included were the Central Sensitization Inventory (CSI), pressure pain thresholds (PPTs) and monofilaments. No consensus was reached on the Sensory Hypersensitivity Scale.

CONCLUSION

In a Delphi study among an international panel of experts, three tests for measuring CS were considered to be suitable for use in general practice: the Central Sensitization Inventory (CSI), pressure pain thresholds (PPTs) and monofilaments.

Patients' Perspectives on the Usability of a Blended Approach to an Integrated Intervention for Patients With Medically Unexplained Physical Symptoms: Mixed Methods Study

Background

Medically unexplained physical symptoms are physical symptoms, such as pain, fatigue, and dizziness, that persist for more than a few weeks and cannot be explained after adequate medical examination. Treatment for preventing the chronicity of symptoms is recommended. A promising approach is identifying patients who are at risk and subsequently offering a blended care intervention that focuses on promoting self-management while using eHealth as a supportive tool. When these interventions match with a patient’s expectations, their effectiveness grows.

Objective

This study aimed to obtain more insights into usability from the patient perspective to improve future interventions.

Methods

A mixed methods design (ie, the use of qualitative and quantitative data) was used. Through semistructured interviews, in-depth insights were gained into patients’ perspectives on usability. The analysis process was continuous and iterative. Data were synthesized and categorized into different themes. The System Usability Scale, which measures the usability of a system, was used to compare participants that found usability to be low, medium, or high. This study was approved by the Medical Ethical Committee Utrecht (approval number: 17-391/C).

Results

Saturation was reached after interviewing 13 participants. The following four themes emerged from the interviews: motivations and expectations prior to participating in the program, the applicability of e-coaching, the role of health care professionals, and the integrated design of the blended approach.

Conclusions

The successful implementation of integrated blended care interventions based on patients’ perspectives requires matching treatments to patients’ individual situations and motivations. Furthermore, personalizing the relative frequency of face-to-face appointments and e-coaching can improve usability.

Identifying persistent somatic symptoms in electronic health records: exploring multiple theory-driven methods of identification

OBJECTIVE

Persistent somatic symptoms (PSSs) are defined as symptoms not fully explained by well-established pathophysiological mechanisms and are prevalent in up to 10% of patients in primary care. The present study aimed to explore methods to identify patients with a recognisable risk of having PSS in routine primary care data.

DESIGN

A cross-sectional study to explore four identification methods that each cover part of the broad spectrum of PSS was performed. Cases were selected based on (1) PSS-related syndrome codes, (2) PSS-related symptom codes, (3) PSS-related terminology and (4) Four-Dimensional Symptom Questionnaire scores and all methods combined.

SETTING

Coded electronic health record data were extracted from 76 general practices in the Netherlands.

PARTICIPANTS

Patients who were registered for at least 1 year during 2014-2018, were included (n=169 138).

OUTCOME MEASURES

Identification methods were explored based on (1) PSS sample sizes and demographics, (2) presence of chronic conditions and (3) healthcare utilisation (HCU) variables. Overlap between methods and practice specific differences were examined.

RESULTS

The percentage of cases identified varied between 0.3% and 7.0% across the methods. Over 58.1% of cases had chronic physical condition(s) and over 33.8% had chronic mental condition(s). HCU was generally higher for cases selected by any method compared with the total cohort. HCU was higher for method B compared with the other methods. In 26.7% of cases, cases were selected by multiple methods. Overlap between methods was low.

CONCLUSIONS

Different methods yielded different patient samples which were general practice specific. Therefore, for the most comprehensive data-based selection of PSS cases, a combination of methods A, C and D would be recommended. Advanced (data-driven) methods are needed to create a more sensitive algorithm for identifying the full spectrum of PSS. For clinical purposes, method B could possibly support screening of patients who are currently missed in daily practice.

The general practitioners perspective regarding registration of persistent somatic symptoms in primary care: a survey

Background

Persistent somatic symptoms (PSS) are common in primary care and often accompanied by an increasing disease burden for both the patient and healthcare. In medical practice, PSS is historically considered a diagnosis by exclusion or primarily seen as psychological. Besides, registration of PSS in electronic health records (EHR) is unambiguous and possibly does not reflect classification adequately. The present study explores how general practitioners (GPs) currently register PSS, and their view regarding the need for improvements in classification, registration, and consultations.

Method

Dutch GPs were invited by email to participate in a national cross-sectional online survey. The survey addressed ICPC-codes used by GPs to register PSS, PSS-related terminology added to free text areas, usage of PSS-related syndrome codes, and GPs’ need for improvement of PSS classification, registration and care.

Results

GPs (n = 259) were most likely to use codes specific to the symptom presented (89.3%). PSS-related terminology in free-text areas was used sparsely. PSS-related syndrome codes were reportedly used by 91.5% of GPs, but this was primarily the case for the code for irritable bowel syndrome. The ambiguous registration of PSS is reported as problematic by 47.9% of GPs. Over 56.7% of GPs reported needing additional training, tools or other support for PSS classification and consultation. GPs also reported needing other referral options and better guidelines.

Conclusions

Registration of PSS in primary care is currently ambiguous. Approximately half of GPs felt a need for more options for registration of PSS and reported a need for further support. In order to improve classification, registration and care for patients with PSS, there is a need for a more appropriate coding scheme and additional training.

Exploring temporal relationships among worrying, anxiety, and somatic symptoms

OBJECTIVES

The role of anxiety symptoms in the development of functional somatic symptoms (FSS) is unknown. Somatic symptoms may be triggered by or give rise to anxiety symptoms. This study aimed to 1) explore interrelationships among within-day worrying, feeling anxious, and somatic symptoms, and 2) investigate the association between these interrelationships and overall level of FSS.

METHODS

This study included 767 participants (83% females, mean age 39 years), who were recruited through an online crowdsourcing study in the Dutch general population. Somatic, and anxiety symptoms were reported thrice daily (6-h intervals) for 30 days using electronic diaries. FSS were assessed at baseline (PHQ-15). Temporal relationships among worrying, feeling anxious, and somatic symptoms were modeled using a multilevel vector autoregressive model.

RESULTS

We observed large heterogeneity in the within-person interrelationships among worrying, feeling anxious and somatic symptoms. Averaged over participants, higher-than-usual somatic symptoms were associated with increases in levels of worrying six hours later (B = 0.017, 95% CI [0.006, 0.027]). At the between-person level, FSS levels predicted the persistence of feeling anxious (B = 0.230 95% CI [0.105, 0.350]) and the carry-over of worrying to feeling anxious over six-hours (B = 0.159, 95% CI [0.031, 0.283]).

CONCLUSIONS

In contrast to what we expected, higher levels of somatic symptoms over multiple weeks were associated with the persistence and carry-over of within-day anxiety-related symptoms. One within-person association between psychological and somatic symptoms during the day was observed, suggesting that, over a time span of 6-h, anxiety symptoms relate to somatic symptoms only in a minority of people from the general population.

Making sense of symptoms, clinicians and systems: a qualitative evaluation of a facilitated support group for patients with medically unexplained symptoms

Objectives

Health services to date have inadequately addressed the physical and mental health needs of patients with medically unexplained symptoms. This qualitative study evaluates a piloted facilitated support group (FSG) developed for patients with medically unexplained symptoms to inform recommendations and resources for this patient population.

Methods

Using a qualitative descriptive design, we conducted and thematically analyzed semi-structured interviews with participants (n = 8) and facilitators (n = 4) to explore their experiences of the facilitated support group. Common themes that captured strengths and challenges of the facilitated support group were identified.

Results

The following key themes were identified through analysis of the data: Participants described 1) feeling validated through sharing similar experiences with peers; 2) learning practical symptom management and coping strategies; and 3) gaining new perspectives for navigating conversations with PCPs.

Conclusions

Our findings show that a facilitated support group may provide additional forms of support and resources for patients with medically unexplained symptoms, filling a gap in currently available clinical care offered by health care professionals. Potential implications: This paper highlights lessons learned that can inform the design and delivery of future supports and resources directed toward optimizing patient care for this underserved patient population. Our findings are relevant to those who are involved in direct patient care or involved in designing and implementing self-management programs.

Barriers and facilitators to the implementation of interventions for medically unexplained symptoms in primary care: A modified Delphi study

OBJECTIVE

Medically Unexplained Symptoms (MUS) are physical symptoms that last for longer than several weeks and for which no (sufficient) somatic explanation can be found. Interventions for treating MUS in primary care are available, but their implementation in daily practice appears difficult. In the current study we aim to explore key barriers and facilitators to the implementation of MUS-interventions in primary care.

METHODS

A three-round modified Delphi study was performed, using the input of 58 experts that are (in)directly involved in the care for patients with MUS (e.g. general practitioners (GPs), GP mental health workers, policy advisors). In the first online questionnaire, we generated ideas about relevant barriers and facilitators on different implementation levels. These ideas were independently coded by two researchers, and reformulated into unique barriers and facilitators. In round two, participants selected the ten most relevant barriers and facilitators from round one, which were ranked on importance in round three.

RESULTS

We identified 42 unique barriers and 57 unique facilitators to the implementation of MUS-interventions. The three highest ranked barriers were all related to time, i.e. too little time for treating complex MUS-patients. The most important facilitator was a positive attitude towards MUS-patients. Results varied somewhat per profession.

CONCLUSION

Key barriers and facilitators to the implementation of MUS-interventions seem to exist on the level of the patient, intervention, professional, organization, and external context. All of these levels should be taken into account in order to increase implementation success of MUS-interventions in primary care.

Development of an eHealth programme for self-management of persistent physical symptoms: a qualitative study on user needs in general practice

Background

Persistent physical symptoms (PPS) are estimated to be present in 17% of patients in general practice. Hence, general practitioners (GPs) play a key role in both the diagnostic assessment and the management of PPS. However, research indicates a need to improve their strategies to support self-help in patients, and eHealth tools may serve as an opportunity. This study aimed to explore patients’ and GPs’ needs related to self-management of PPS. The study was designed to inform the future development of eHealth interventions in this field.

Methods

This qualitative study was based on 20 semi-structured interviews (6 GPs and 14 patients with PPS). Interviews were audiotaped, transcribed verbatim and analysed through a five-step thematic analysis approach. First, we conducted an inductive analysis to identify and explore emerging subthemes. Second, using a deductive mapping strategy, we categorised the derived subthemes according to the COM-B behaviour change model and its three domains: capability, opportunity and motivation.

Results

We identified eleven subthemes in the patient interviews and seven subthemes in the GP interviews. Several unmet needs emerged. First, we identified a need to consider PPS early in the illness trajectory by taking a bio-psycho-social approach. Second, both patients and GPs need better skills to manage uncertainty. Third, hope is important for the patients. Fourth, patients need guidance from their GP in how to self-manage their PPS.

Conclusions

This study provides important insight into key issues and needs related to capability, opportunity and motivation that should be addressed in the design of future eHealth self-management interventions targeting patients with PPS in general practice in order to support and improve care.

Development and User Experiences of a Biopsychosocial Interprofessional Online Course on Persistent Somatic Symptoms

Background: Communication between healthcare providers and patients with persistent somatic symptoms (PSS) is frequently hampered by mutual misunderstanding and dissatisfaction. Methods: We developed an online, interprofessional course to teach healthcare providers the knowledge, skills, and attitude they need to diagnose and treat PSS in a patient-centered manner based on the biopsychosocial model. The course consisted of six modules of 45-60 min. Each module contained different types of assignments, based on six cases: videos, discussion boards, reading assignments, polls, and quizzes. For this study, we included (1) medical residents, following the course as part of their residency training, and (2) healthcare providers (general practitioners, medical specialists, physiotherapists, nurses, and psychologists), following the course as continuing vocational training. Throughout the course, participants were asked to fill out online surveys, enquiring about their learning gains and satisfaction with the course. Results: The biopsychosocial approach was integrated across the modules and teached health care workers about recent insights on biological, psychological and social aspects of PSS. In total, 801 participants with a wide variety in clinical experience started the course; the largest groups of professionals were general practitioners (N = 400), physiotherapists (N = 124) and mental healthcare workers (N = 53). At the start of the course, 22% of the participants rated their level of knowledge on PSS as adequate. At the end of the course, 359 participants completed the evaluation questionnaires. Of this group, 81% rated their level of knowledge on PSS as adequate and 86% felt that following the course increased their competencies in communicating with patients with PSS (N = 359). On a scale from 1 to 10, participants gave the course a mean grade of 7.8 points. Accordingly, 85% stated that they would recommend the course to a colleague. Conclusion: Our course developed in a co-design process involving multiple stakeholders can be implemented, is being used, and is positively evaluated by professionals across a variety of health care settings.

The challenges of chronic pain and fatigue

In this review, we explore the challenges of chronic pain and fatigue in clinical practice. Both pain and fatigue are common, troubling and frequently overlapping symptoms, and we describe both the clinical burden and the 'clinical problem'. We explore commonly associated symptoms and possible pathological associations, including variant connective tissue (joint hypermobility), small fibre neuropathy, mast cell activation, dysregulated inflammatory and interoceptive processes, which may inform treatment targets. We suggest a multidisciplinary management approach.

Demographic and health-related factors associated with reduced work functioning in people with moderate medically unexplained physical symptoms: a cross-sectional study

BACKGROUND

Medically unexplained physical symptoms (MUPS) are a leading cause of reduced work functioning. It is not known which factors are associated with reduced work functioning in people with moderate MUPS. Insight in these factors can contribute to prevention of reduced work functioning, associated work-related costs and in MUPS becoming chronic. Therefore, the aim of this study was to identify which demographic and health-related factors are associated with reduced work functioning, operationalized as impaired work performance and absenteeism, in people with moderate MUPS.

METHODS

Data of 104 participants from an ongoing study on people with moderate MUPS were used in this cross-sectional study. Ten independent variables were measured at baseline to determine their association with reduced work functioning: severity of psychosocial symptoms (four domains, measured with the Four-Dimensional Symptom Questionnaire), physical health (RAND 36-Item Health Survey), moderate or vigorous physical activity (Activ8 activity monitor), age, sex, education level and duration of complaints. Two separate multivariable linear regression analyses were performed with backward stepwise selection, for both impaired work performance and absenteeism.

RESULTS

Absenteeism rate rose with 2.5 and 0.6% for every increased point on the Four-Dimensional Symptom Questionnaire for domain 'depression' (B = 0.025, SE = 0.009, p = .006) and domain 'somatization' (B = 0.006, SE = 0.003, p = .086), respectively. An R² value of 0.118 was found. Impaired work performance rate rose with 0.2 and 0.5% for every increased point on the Four-Dimensional Symptom Questionnaire for domain 'distress' (B = 0.002, SE = 0.001, p = .084) and domain 'somatization' (B = 0.005, SE = 0.001, p < .001), respectively. An R² value of 0.252 was found.

CONCLUSIONS

Severity of distress, probability of a depressive disorder and probability of somatization are positively associated with higher rates of reduced work functioning in people with moderate MUPS. To prevent long-term absenteeism and highly impaired work performance severity of psychosocial symptoms seem to play a significant role. However, because of the low percentage of explained variance, additional research is necessary to gain insight in other factors that might explain the variance in reduced work functioning even better.

Association of Somatic Symptom Severity With Sociodemographic Parameters In Patients With Medically Unexplained Physical Symptoms: A Cross-Sectional Study From a Tertiary Care Center in India

Background

There is a paucity of studies assessing the severity of somatic symptoms in medically unexplained physical symptoms (MUPS) from Medicine outpatient department (OPD).

Methodology

This cross-sectional study was conducted in Medicine OPD of a tertiary care hospital in India, in which 245 MUPS-diagnosed patients out of 976 consecutive screened patients were evaluated for the severity of somatic symptoms (by administering the Patient Health Questionnaire-15) and its sociodemographic correlates.

Results

Out of 245 recruited patients, three-fourth had a significant severity level of somatic symptoms. High level of somatic symptom severity was more common in females (p ≤ 0.001), married patients (p = 0.011), rural dwellers (p = 0.035), less educated (p = 0.003), and those with lower socioeconomic status (p = 0.001).

Conclusions

Patients with MUPS have a high level of somatic symptom severity with certain sociodemographic correlates. Further research should be conducted to investigate the reasons for this and to formulate a cost-effective treatment strategy.

Health Care Use and Costs of Children, Adolescents, and Young Adults With Somatic Symptom and Related Disorders

IMPORTANCE

Somatic symptom and related disorders are highly prevalent mental health disorders among young people. Presentation can be varied, and patients often face long delays and see multiple practitioners to receive a diagnosis.

OBJECTIVE

To evaluate the health care use and costs in a population-based sample of children and young people with somatic symptom and related disorders in Ontario, Canada.

DESIGN, SETTING, AND PARTICIPANTS

This population-based cohort study used linked health and administrative databases in Ontario, Canada, where health services are funded through a universal single-payer health insurance plan. Participants included children aged 4 to 12 years, adolescents aged 13 to 17 years, and young adults aged 18 to 24 years residing in Ontario, Canada, during the period of April 1, 2008, to March 31, 2015. Included participants had a first health record diagnosis of somatic symptom and related disorders and were grouped based on the setting of their index somatic symptom and related disorders contact: outpatient, emergency department, or inpatient. Data were analyzed from August 1, 2017, to February 1, 2018.

EXPOSURES

One year before and 1 year after diagnosis of somatic symptom and related disorders.

MAIN OUTCOMES AND MEASURES

Outcome measures included overall and mental health-specific ambulatory and acute care visits and overall health system costs and sector-specific costs.

RESULTS

A total of 33 272 patients (median [interquartile range {IQR}] age, 20 [16-22] years; 17 387 female [52.3%]) were included in the analysis. Among these patients, 3875 (11.6%) were aged 4 to 12 years, 7273 (21.9%) were aged 13 to 17 years, and 22 124 (66.5%) were aged 18 to 24 years. A total of 17 893 (53.8%) had their index visit as outpatients, whereas 13 310 (40.0%) and 2069 (6.2%) were diagnosed in the emergency department and inpatient settings, respectively. Ambulatory physician visits were frequent and persisted 1 year after diagnosis within each setting (before vs after 1 year, median [IQR] visits, inpatient setting: 7 [3-13] vs 7 [3-13]; emergency department setting: 4 [2-8] vs 4 [2-9]; outpatient setting: 3 [1-7] vs 4 [2-7]; P < .001). After diagnosis, many did not receive physician-delivered mental health care (35.3% [730 of 2069] in an inpatient setting, 59.1% [7866 of 13 310] in an emergency department setting, 58.5% [10 467 of 17 893] in an outpatient setting; P < .001). Acute care use was frequent and remained so after diagnosis across settings. Of those hospitalized as inpatients at diagnosis, 37.7% (779 of 2069) were readmitted within 1 year. Mean (SD) 2-year patient costs were CAD$9845 ($39 725) (median [IQR], $2401 [$960-$7019]). Hospitalized patients had a 2-year mean (SD) cost of $51 424 ($100 416) (median [IQR], $21 997 [$12 510-$45 841]) per-patient expenditure.

CONCLUSION AND RELEVANCE

This study found that children and young people with somatic symptom and related disorders frequently used the health system with substantial health system costs before and after diagnosis. Many of these patients did not receive physician-delivered mental health care. These findings suggest that this population may be under-recognized, and initiatives for early recognition and engagement with mental health support may be warranted.

Prevalence of DSM-5 somatic symptom disorder in Chinese outpatients from general hospital care

OBJECTIVE

We aimed to explore the prevalence of somatic symptom disorder (SSD) according to DSM-5 criteria in Chinese outpatients from general hospital departments.

METHODS

This multicentre cross-sectional study enrolled 699 patients from outpatient departments, including the neurology, gastroenterology, Traditional Chinese Medicine [TCM] and psychosomatic medicine departments, in five cities in China. The structured clinical interview for DSM-5 (SCID-5) for SSD was administered by trained clinical professionals to diagnose SSD.

RESULTS

SSD was diagnosed in 33.8% (236/697) of all enrolled patients. The prevalence of SSD differed significantly among the departments (χ² = 34.049, df = 2, p ≤0.001). No differences were found between SSD patients and non-SSD patients in terms of gender, residence, marital and living statuses, family income, education, employment status and lifestyle factors. However, patients with SSD reported higher levels of depression, health-related and general anxiety, lower physical and mental quality of life, higher frequency of doctor visits, increased time devoted to physical symptoms and longer duration of somatic symptoms. In a binary linear regression analysis, SSD was significantly associated with an increase in health-related anxiety, time devoted to symptoms and impact of somatic symptoms on daily life. The explained variance was Nagelkerke R² = 0.45.

CONCLUSION

There is a high prevalence of SSD in Chinese general hospital outpatient clinics. The diagnosis is associated with high levels of emotional distress and low quality of life. There is a danger of over-diagnosis if we include the mild and moderate forms of SSD. Future studies are warranted to investigate the prevalence of SSD in inpatient departments and the development of psychological interventions for these patients.

Quality of life in primary care patients with moderate medically unexplained physical symptoms

PURPOSE

Medically Unexplained Physical Symptoms (MUPS) have a large impact on patient's quality of life. Most studies have been limited to chronic MUPS and thus, little is known about moderate MUPS. Improved knowledge concerning determinants influencing quality of life in moderate MUPS patients can be helpful in managing MUPS. This study is aimed at describing the common characteristics seen in moderate MUPS patients and compare them with characteristics seen in chronic MUPS patients and general population. We also identified determinants of the physical and mental components of quality of life in moderate MUPS patients.

METHODS

In a cross-sectional study, moderate MUPS patients (n = 160) were compared with chronic MUPS patients (n = 162) and general population (n = 1742) based on demographic characteristics and patient's quality of life. Multivariable linear regression analyses were performed to identify determinants associated with a patient's quality of life, assessed with the RAND-36.

RESULTS

Moderate MUPS patients experienced a better quality of life than chronic MUPS patients, but a worse quality of life as compared to the general population. Determinants associated with the physical and mental components of quality of life explain 49.1% and 62.9% of the variance, respectively.

CONCLUSION

Quality of life of patients with MUPS varies with MUPS disease stage. Based on their quality of life scores, moderate MUPS patients would be adequately distinguished from chronic MUPS patients. Half of the variance in the physical component and almost two thirds of the mental component would be explained by a number of MUPS-related symptoms and perceptions.

Personalized, Web-Based, Guided Self-Help for Patients With Medically Unexplained Symptoms in Primary Care: Protocol for a Randomized Controlled Trial

Background

Medically unexplained symptoms (MUS) constitute a major health problem because of their high prevalence, the suffering and disability they cause, and the associated medical costs. Web-based interventions may provide an accessible and convenient tool for managing MUS. We developed a personalized, Web-based, guided self-help intervention for MUS in primary care (Grip self-help) and would compare its effectiveness with that of usual care.

Objective

This paper aims to describe the rationale, objectives, and design of a pragmatic randomized controlled trial (RCT) assessing the effectiveness of Grip self-help.

Methods

For a pragmatic multicenter RCT, 165 adult patients with mild to moderate MUS will be recruited through general practices in the Netherlands. Randomization will be performed at general practice level. Over the course of several months, patients in the intervention group will receive a personalized set of Web-based self-help exercises, targeting the unhelpful cognitions, emotions, behaviors, and social factors that are relevant to them. The intervention is guided by a general practice mental health worker. The control group will receive care-as-usual. Primary outcome is physical health-related quality of life (RAND-36 or 36-item general health survey, physical component score). Secondary outcomes include severity of physical and psychological symptoms, mental health–related quality of life, cost-effectiveness, and acceptability. Assessments will take place at baseline, end of treatment, and at 16-, 26-, and 52-week follow-ups.

Results

Recruitment started in December 2018, and enrolment is ongoing. The first results are expected to be submitted for publication in December 2021.

Conclusions

To our knowledge, this is the first study to combine the concepts of electronic health, self-help, and personalized medicine in the treatment of MUS. By improving the quality of life and reducing symptoms of patients with MUS, Grip self-help has the potential to reduce costs and conserve scarce health care resources.

Hospitalized Patients with Medically Unexplained Physical Symptoms: Clinical Context and Economic Costs of Healthcare Management

Medically Unexplained Physical Symptoms (MUPS) are physical symptoms without a medical explanation. This study collected data from hospitalized patients presenting MUPS, aiming to draw a clinical and socio-demographic profile of patients with MUPS, to explore psychopathological correlations of Somatic Symptoms Disorder (SSD) diagnosis, and to estimate economic costs related to hospital management for MUPS. The cross-sectional study consisted in the evaluation of data referring to hospitalized patients admitted between 2008 and 2018 in a teaching hospital in Northern Italy. A total of 273 patients presenting MUPS have been hospitalized. The sample showed a prevalence of female, married and employed patients. The most frequent wards involved are Neurology, Internal Medicine and Short Unit Stay. The most common symptoms found are headache, pain, syncope and vertigo. There is no evidence that a history of medical disease is associated with a diagnosis of SSD. A personality disorder diagnosis in patients with MUPS was associated with increased probability of having a diagnosis of SSD. A marginally significant positive association emerged with anxiety disorders, but not with depressive disorder. The overall estimated cost of hospitalization for patients with MUPS is 475'409.73 €. The study provides the investigation of a large number of patients with MUPS and a financial estimate of related hospitalization costs.

Identifying Treatment Modalities for a Multidisciplinary and Blended Care Intervention for Patients With Moderate Medically Unexplained Physical Symptoms: Qualitative Study Among Professionals

BACKGROUND

Medically unexplained physical symptoms (MUPS) are a substantial health problem in primary care with a high burden for patients, general practitioners, and the health care system. Most studies focus on chronic MUPS patients. Little research is conducted in patients with moderate MUPS, and an effective primary care intervention for prevention of chronic MUPS is lacking.

OBJECTIVE

The objective of our study was to identify treatment modalities based on expert opinions for the development of a multidisciplinary and blended intervention for patients with moderate MUPS to prevent chronicity.

METHODS

Two focus groups with 8 and 6 experts (general practitioners, physical therapists, psychologists, and mental health nurses) were carried out. The focus groups were structured using the nominal group technique.

RESULTS

A total of 70 ideas were generated from two nominal group meetings, and 37 of these got votes, were included in the rank order, and were sorted into 8 separate themes. According to the participants, the most important treatment modalities for a multidisciplinary and blended intervention in patients with moderate MUPS were (1) coaching to a healthier lifestyle, (2) education regarding psychosocial factors, (3) therapeutic neuroscience education, (4) multidisciplinary intake, (5) multidisciplinary cooperation and coordination, (6) relaxation or body awareness exercises, (7) clear communication by professionals to the patient, and (8) graded activity. Five independent researchers checked the ideas and linked them to themes to confirm the content analysis and check the validity of the themes.

CONCLUSIONS

From professional expert perspectives, 8 themes should be included in a multidisciplinary and blended intervention to prevent chronicity. These themes provide a first step in developing an intervention for patients with moderate MUPS. Future research should focus on further development steps in which patients with moderate MUPS should be involved to determine if the intervention matches their needs.

Predictors for use of psychosocial services in patients with metastatic colorectal cancer receiving first line systemic treatment

BACKGROUND

Patients with advanced disease experience high levels of psychological distress, yet there is low uptake of psychosocial services offered to patients who screened positive for distress. In this study we aimed to identify predictors for use of psychosocial services in patients with metastatic colorectal cancer (mCRC) receiving first line chemotherapy enrolled in a prospective cluster randomized trial (CRT).

METHODS

Patients completed measures on psychological distress, physical distress, and quality of life at baseline. Demographics, clinical characteristics at baseline and clinical events during treatment (e.g. severe adverse events, clinical benefit) were extracted from patient records. Patients reported psychosocial service utilization in- and outside the hospital after 10, 24 and 48 weeks of treatment. Multivariable logistic regression models were used to identify predictors for the use of psychosocial services.

RESULTS

Out of 349 patients, seventy patients (20.0%) used psychosocial support services during the follow-up period. Use of psychosocial services was associated with younger age, a higher educational level, presence of more pain (at baseline), and the expressed need to talk to a professional (at baseline). In addition, patients without progressive disease within the first ten weeks of treatment were more likely to use psychosocial services .

CONCLUSIONS

One in five patients with mCRC receiving first line palliative treatment used psychosocial services during this prospective longitudinal CRT. Sociodemographic factors (age, education), clinical factors (pain and no progressive disease) and the expressed need to talk to a professional predicted use of psychosocial services. Identification of these predictors may contribute to the understanding of factors that determine the need for psychosocial services.

Cost-effectiveness of interventions for medically unexplained symptoms: A systematic review

BACKGROUND

In primary and secondary care medically unexplained symptoms (MUS) or functional somatic syndromes (FSS) constitute a major burden for patients and society with high healthcare costs and societal costs. Objectives were to provide an overview of the evidence regarding the cost-effectiveness of interventions for MUS or FSS, and to assess the quality of these studies.

METHODS

We searched the databases PubMed, PsycINFO, the National Health Service Economic Evaluation Database (NHS-EED) and the CEA registry to conduct a systematic review. Articles with full economic evaluations on interventions focusing on adult patients with undifferentiated MUS or fibromyalgia (FM), irritable bowel syndrome (IBS) and chronic fatigue syndrome (CFS), with no restrictions on comparators, published until 15 June 2018, were included. We excluded preventive interventions. Two reviewers independently extracted study characteristics and cost-effectiveness data and used the Consensus on Health Economic Criteria Checklist to appraise the methodological quality.

RESULTS

A total of 39 studies out of 1,613 articles met the inclusion criteria. Twenty-two studies reported costs per quality-adjusted life year (QALY) gained and cost-utility analyses (CUAs). In 13 CUAs the intervention conditions dominated the control conditions or had an incremental cost-effectiveness ratio below the willingness-to-pay threshold of € 50,000 per QALY, meaning that the interventions were (on average) cost-effective in comparison with the control condition. Group interventions focusing on MUS (n = 3) or FM (n = 4) might be more cost-effective than individual interventions. The included studies were heterogeneous with regard to the included patients, interventions, study design, and outcomes.

CONCLUSION

This review provides an overview of 39 included studies of interventions for patients with MUS and FSS and the methodological quality of these studies. Considering the limited comparability due to the heterogeneity of the studies, group interventions might be more cost-effective than individual interventions.

REGISTRATION

Study methods were documented in an international prospective register of systematic reviews (PROSPERO) protocol, registration number: CRD42017060424.

Attachment and medically unexplained somatic symptoms: The role of mentalization

Previous research has found an association between insecure attachment and increased somatization in adults. However, the mechanisms underlying this association are unknown. In the present study, we examined whether the association between attachment insecurity and somatization in psychiatric patients diagnosed with medically unexplained somatic symptoms (MUSS) is mediated by mentalization deficits. Attachment security of 58 outpatients diagnosed with MUSS was measured with the Experiences in Social Relationships Questionnaire (ECR). Difficulty with understanding own emotions was measured with the Toronto Alexithymia Scale-20. In addition, others' mental state comprehension was measured with the Reading the Mind in the Eyes Test (RMET). Somatic symptom severity experienced by MUSS patients was related to attachment anxiety and alexithymia. These associations remained significant after controlling for sex, age, medication use, and depressive symptoms. Moreover, alexithymia mediated the association between anxious attachment and severity of somatic symptoms. Somatic symptom severity was also related to better RMET performance, although this association was not significant after controlling for sex, age, medication use, and depressive symptoms. Our findings may indicate that individuals with an anxious attachment style have difficulties in clarifying own emotions. This may in turn result in somatic experience of emotional distress and risk for development of MUSS.

Organizational justice, justice climate, and somatic complaints: A multilevel investigation

OBJECTIVE

Organizational justice refers to perceived fairness at the workplace. Individual perceptions of injustice have been linked to reduced mental and physical health. However, perceptions of injustice also exist at the aggregate level of departments, reflecting a shared perception, denoted as justice climate. There is evidence that this shared perception independently predicts individual distress levels (e.g., anxiety, depression), which might negatively affect somatic symptom perception and reporting. Hence, the objective of this study was to examine whether individual perceptions of poor justice as well as a poor justice climate are related to elevated somatic complaints. In addition, this study examined if justice climate moderates the relationship between individual-level justice perceptions and somatic symptom reporting.

METHODS

Cross-sectional data from a large industrial manufacturing company was used, involving 1,102 employees in 31 departments. A validated scale covering interactional and procedural justice assessed individual-level organizational justice. A 19-item symptom checklist measured somatic complaints. Multilevel analyses estimated individual-level associations (within-department effects) with somatic complaints, department-level associations (between-department effects), and the cross-level interaction of both.

RESULTS

Individual-level justice perceptions were negatively associated with somatic complaints. Collective justice climate was likewise significantly associated with somatic complaints. There was no indication for a moderation effect of justice climate.

CONCLUSION

A poor justice climate correlated positively with individual somatic complaints while controlling for individual perceptions, i.e., above and beyond individual justice perceptions. These findings may imply that interventions targeting department-level perceptions of justice may have the potential to reduce individual somatic complaints beyond the effects of individual-level interventions.

Effectiveness of a Blended Multidisciplinary Intervention for Patients with Moderate Medically Unexplained Physical Symptoms (PARASOL): Protocol for a Cluster Randomized Clinical Trial

BACKGROUND

Medically unexplained physical symptoms are an important health problem in primary care, with a spectrum from mild to chronic. The burden of chronic medically unexplained physical symptoms is substantial for patients, health care professionals, and society. Therefore, early identification of patients with moderate medically unexplained physical symptoms is needed in order to prevent chronicity. The preventive screening of medically unexplained physical symptoms (PRESUME) screening method was developed using data from the electronic medical record of the patients' general practitioner and demonstrated its prognostic accuracy to identify patients with moderate medically unexplained physical symptoms. In the next step, we developed a proactive blended and integrated mental health and physical therapy intervention program (PARASOL) to reduce complaints of moderate medically unexplained physical symptoms, stimulate self-management, and prevent chronicity.

OBJECTIVE

The primary objective of this study is to investigate the effectiveness of the blended PARASOL intervention on the impact of symptoms and quality of life in patients with moderate medically unexplained physical symptoms compared with usual care. Secondary objectives are to study the effect on severity of physical and psychosocial symptoms, general health, physical behavior, illness perception, and self-efficacy in patients with moderate medically unexplained physical symptoms as well as to determine the cost-effectiveness of the program.

METHODS

This paper presents the study protocol of a multicenter cluster randomized clinical trial. Adult patients with moderate medically unexplained physical symptoms will be identified from electronic medical record data using the PRESUME screening method and proactively recruited for participation in the study. Cluster randomization will be performed at the level of the participating health care centers. In total 248 patients with moderate medically unexplained physical symptoms (124 patients per arm) are needed. The PARASOL intervention is a 12-week blended primary care program consisting of 4 face-to-face consultations with the mental health nurse and 5 physical therapy sessions, supplemented with a Web-based program. The Web-based program contains (1) information modules and videos on self-management and educative themes, (2) videos and instructions on prescribed home exercises, and (3) assignments to gradually increase the physical activity. The program is directed at patients' perception of symptoms as well as modifiable prognostic risk factors for chronicity using therapeutic neuroscience education. It encourages self-management, as well as an active lifestyle using a cognitive behavioral approach and graded activity. Primary outcomes are impact of symptoms and quality of life. Secondary outcomes are severity of physical and psychosocial symptoms, general health, physical behavior, illness perceptions, self-efficacy, and cost-effectiveness. All measurements will be performed at baseline, 3 and 12 months after baseline. Retrospective cost questionnaires will also be sent at 6 and 9 months after baseline and these will be used for the cost-effectiveness analysis.

RESULTS

The intervention has been developed, and the physical therapists and mental health nurses in the participating experimental health care centers have received two days of training on the content of the blended PARASOL intervention. The recruitment of health care centers started in June 2016 and inclusion of patients began in March 2017. Follow-up assessments of patients are expected to be completed in March 2019.

CONCLUSIONS

This study is the first randomized clinical trial to determine the effectiveness (including cost-effectiveness) of a proactive, blended, and integrated mental health and physical therapy care program for patients with moderate medically unexplained physical symptoms. The findings will help to improve the treatment for patients with moderate medically unexplained physical symptoms and prevent chronicity.

Medically unexplained physical symptoms in patients attending a medical outpatient clinic in a tertiary hospital in North India

OBJECTIVE

Medically unexplained physical symptoms (MUPS) are commonly seen across health care settings. Earlier studies have focussed on prevalence, cost-utilization and burden. Data from India is scarce. Patients with persistent MUPS have more impairment and psychological distress. This study was designed to assess psychological morbidity, health anxiety (HA), somatic symptom load, disability, quality of life (QOL) in patients with persistent MUPS presenting to a general medical outpatient service and compare it with patients with medically explained physical symptoms (MEPS).

METHODS

The study was conducted in the outpatient service of the Department of Internal Medicine in a tertiary hospital in North India. Persistent MUPS was defined as physical symptoms of at least 3 months duration leading to dysfunction and with no identifiable medical cause. 70 patients with persistent MUPS and MEPS each were recruited. Psychiatric morbidity was assessed using the Mini International Neuropsychiatric interview, somatic symptom load with Patient Health Questionniare-15 (PHQ-15), HA with Whiteley Index, disability with WHODAS 2.0 and QOL with WHOQOL-Bref.

RESULTS

Both the groups were comparable on socio-demography and length of symptoms. Prevalence of psychiatric disorders and HA was significantly greater in MUPS. Patients with persistent MUPS had significantly more health care utilization, number and burden of somatic symptoms, greater disability and worse QOL.

CONCLUSIONS

Patients with persistent MUPS have a different profile when compared to MEPS. There is a need to screen and identify patients with MUPS and manage them keeping in mind the psychological factors and chronic nature and number of symptoms.

Novel primary care treatment package for patients with medically unexplained symptoms: a cohort intervention study

Background

Existing care models for patients with persistent medically unexplained symptoms (MUS) do not adequately address the needs of these patients. New and innovative intervention strategies are necessary to achieve better health and corresponding economic outcomes.

Aim

To explore the feasibility of implementing a pragmatic care package that provides primary care treatment for patients with persistent MUS and to evaluate recruitment, retention, and acceptability as well as the potential impact on clinical outcomes and service utilisation.

Design & setting

Prospective cohort intervention study involving a cluster of seven GP surgeries in Newham, East London, providing a 'One-Stop-Shop' primary care treatment service.

Method

The care package included: identification, assessment, engagement, psychoeducation, and a choice of group interventions (mindfulness-based stress reduction [MBSR] and body-oriented psychological therapy [BOPT]). Baseline and follow-up data on somatic symptom levels (PHQ-15), health-related quality of life (SF-36, EQ-5D) and service utilisation was analysed.

Results

In total, 145 patients were referred and assessed for eligibility, and 93 were included in the study. Participants engaged well with different components of the care package and gained significant improvements in somatic symptom levels with corresponding increases of quality-of-life ratings and a reduction in healthcare utilisation (GP contacts and referrals to specialist services) as well as associated healthcare costs.

Conclusion

The primary care treatment package can be successfully implemented in primary care at a relatively low cost and easily adopted into routine care. The body-oriented approach is well accepted by clinicians and patients. Controlled trials should be conducted to test the efficacy of the treatment package.

Diagnostic barriers for somatic symptom disorders in primary care: study protocol for a mixed methods study in Germany

INTRODUCTION

Somatoform or somatic symptom disorders ((S)SD) are common and have a negative impact on the patients' health-related quality of life, healthcare use and costs. In primary care, which is central to the management of (S)SD, diagnosis and treatment tend to be delayed. There is a significant lack of evidence regarding the barriers in the diagnostic process of (S)SD in primary care and how interventions should be tailored to address them. The aim of this study is to analyse the diagnostic process in primary care that results in the diagnosis or non-diagnosis of a (S)SD.

METHODS AND ANALYSIS

This mixed methods study will investigate the topic with qualitative methods, subsequently proceeding to a quantitative phase where the initial results will be validated and/or generalised. First, focus groups will explore meanings and patterns, inconsistencies and conflicts in general practitioners' (GPs) thoughts and behaviours when diagnosing (S)SD. Second, the results of these focus groups will be used to develop interview guidelines for subsequent face-to-face interviews. Patients and their treating GPs will be interviewed separately on how they experience the history of illness, the diagnostic process and treatment. Third, based on the results of the first two study parts, a questionnaire will be derived and a nationwide survey among German GPs will be conducted, quantifying the barriers and difficulties identified before.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Ethics Committee of the Hamburg Medical Association, Germany (approval number PV4763). The results of this study will be disseminated through conference presentation and publications in peer-reviewed journals.

TRIAL REGISTRATION NUMBER

The study is registered in the German Clinical Trial Register (DRKS), DRKS-ID DRKS00009736.

High healthcare utilization near the onset of medically unexplained symptoms

OBJECTIVE

Patients with medically unexplained syndromes (MUS) often do not receive appropriate healthcare. A critical time for effective healthcare is the inception of MUS. The current study examined data from a prospective longitudinal study of Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) soldiers to understand the relationship of increasing physical symptom burden to healthcare utilization.

METHODS

Data was examined from a prospective study of OEF/OIF soldiers assessed before and one year after deployment (n=336). Physical symptom burden was measured with the Patient Health Questionnaire (PHQ-15). Analyses were conducted with polynomial regression and response surface analysis (RSA).

RESULTS

Increases in physical symptom burden predicted greater healthcare utilization one year after deployment: primary care practitioner (slope=-0.26, F=4.07, p=0.04), specialist (slope=-0.43, F=8.67, p=0.003), allied health therapy (e.g., physical therapy) (slope=-0.41, F=5.71, p=0.02) and mental health (slope=-0.32, F=4.04, p=0.05). There were no significant difference in utilization between those with consistently high levels and those with increases in physical symptom burden.

CONCLUSION

This is the first prospective study to examine, and show, a relationship between onset of clinically significant physical symptoms and greater healthcare utilization. Our data suggest that patients with increasing physical symptom burden have the same level of healthcare as patients with chronic physical symptom burden. Needed next steps are to better understand the quality of care at inception and determine how to intervene so that recommended approaches to care are provided from the onset.

Economic evaluation of multidisciplinary rehabilitation treatment versus cognitive behavioural therapy for patients with chronic fatigue syndrome: A randomized controlled trial

BACKGROUND

A multi-centre RCT has shown that multidisciplinary rehabilitation treatment (MRT) is more effective in reducing fatigue over the long-term in comparison with cognitive behavioural therapy (CBT) for patients with chronic fatigue syndrome (CFS), but evidence on its cost-effectiveness is lacking.

AIM

To compare the cost-effectiveness of MRT versus CBT for patients with CFS from a societal perspective.

METHODS

A multi-centre randomized controlled trial comparing MRT with CBT was conducted among 122 patients with CFS diagnosed using the 1994 criteria of the Centers for Disease Control and Prevention and aged between 18 and 60 years. The societal costs (healthcare costs, patient and family costs, and costs for loss of productivity), fatigue severity, quality of life, quality-adjusted life-year (QALY), and cost-effectiveness ratios (ICERs) were measured over a follow-up period of one year. The main outcome of the cost-effectiveness analysis was fatigue measured by the Checklist Individual Strength (CIS). The main outcome of the cost-utility analysis was the QALY based on the EuroQol-5D-3L utilities. Sensitivity analyses were performed, and uncertainty was calculated using the cost-effectiveness acceptability curves and cost-effectiveness planes.

RESULTS

The data of 109 patients (57 MRT and 52 CBT) were analyzed. MRT was significantly more effective in reducing fatigue at 52 weeks. The mean difference in QALY between the treatments was not significant (0.09, 95% CI: -0.02 to 0.19). The total societal costs were significantly higher for patients allocated to MRT (a difference of €5,389, 95% CI: 2,488 to 8,091). MRT has a high probability of being the most cost effective, using fatigue as the primary outcome. The ICER is €856 per unit of the CIS fatigue subscale. The results of the cost-utility analysis, using the QALY, indicate that the CBT had a higher likelihood of being more cost-effective.

CONCLUSIONS

The probability of being more cost-effective is higher for MRT when using fatigue as primary outcome variable. Using QALY as the primary outcome, CBT has the highest probability of being more cost-effective.
