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

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

Objectives: The main objective of the current study is to compare chronic pain characteristics of older patients with Medically Unexplained Symptoms (MUS), to those of patients with Medically Explained Symptoms (MES), and to those of patients with Major Depressive Disorder (MDD). Method: By combining data from the OPUS and NESDO study, we compared pain characteristics of 102 older (&gt;60 years) MUS-patients to 145 older MES-patients and 275 older MDD-patients in a case-control study design. Group differences were analyzed using ANCOVA, adjusted for demographic and physical characteristics. Linear regression was applied to examine the association between pain characteristics and somatization (BSI-53 somatization scale) and health anxiety (Whitely Index). Results: Older MUS-patients have approximately two times more chance of having chronic pain when compared to older MES-patients (OR = 2.01; p = .013) but equal chances as opposed to MDD-patients. After adjustments, MUS-patients report higher pain intensity and disability scores and more pain locations when compared to MES-patients, but equal values as MDD-patients. Health anxiety and somatization levels were positively associated with the number of pain sites in MUS-patients, but not with pain severity or disability. Conclusion: Older MUS-patients did not differ from MDD-patients with respect to any of the chronic pain characteristics, but had more intense and disabling pain, and more pain locations when compared to older MES-patients.</p

clag9 Is Not Essential for PfEMP1 Surface Expression in Non-Cytoadherent Plasmodium falciparum Parasites with a Chromosome 9 Deletion

BACKGROUND: The expression of the clonally variant virulence factor PfEMP1 mediates the sequestration of Plasmodium falciparum infected erythrocytes in the host vasculature and contributes to chronic infection. Non-cytoadherent parasites with a chromosome 9 deletion lack clag9, a gene linked to cytoadhesion in previous studies. Here we present new clag9 data that challenge this view and show that surface the non-cytoadherence phenotype is linked to the expression of a non-functional PfEMP1. METHODOLOGY/PRINCIPAL FINDINGS: Loss of adhesion in P. falciparum D10, a parasite line with a large chromosome 9 deletion, was investigated. Surface iodination analysis of non-cytoadherent D10 parasites and COS-7 surface expression of the CD36-binding PfEMP1 CIDR1α domain were performed and showed that these parasites express an unusual trypsin-resistant, non-functional PfEMP1 at the erythrocyte surface. However, the CIDR1α domain of this var gene expressed in COS-7 cells showed strong binding to CD36. Atomic Force Microscopy showed a slightly modified D10 knob morphology compared to adherent parasites. Trafficking of PfEMP1 and KAHRP remained functional in D10. We link the non-cytoadherence phenotype to a chromosome 9 breakage and healing event resulting in the loss of 25 subtelomeric genes including clag9. In contrast to previous studies, knockout of the clag9 gene from 3D7 did not interfere with parasite adhesion to CD36. CONCLUSIONS/SIGNIFICANCE: Our data show the surface expression of non-functional PfEMP1 in D10 strongly indicating that genes other than clag9 deleted from chromosome 9 are involved in this virulence process possibly via post-translational modifications

Quality indicators for collaborative care networks in persistent somatic symptoms and functional disorders:a modified delphi study

BACKGROUND: Care for persistent somatic symptoms and functional disorders (PSS/FD) is often fragmented. Collaborative care networks (CCNs) may improve care quality for PSS/FD. Effectiveness likely depends on their functioning, but we lack a straightforward quality evaluation system. We therefore aimed to develop quality indicators to evaluate CCNs for PSS/FD.METHOD: Using an online three-round modified Delphi process, an expert panel provided, selected and ranked quality indicators for CCNs in PSS/FD. Recruited experts were diverse healthcare professionals with relevant experience in PSS/FD care in the Netherlands.RESULTS: The expert panel consisted of 86 professionals representing 15 disciplines, most commonly physiotherapists, psychologists and medical specialists. 58% had more than 10 years experience in PSS/FD care. Round one resulted in 994 quotations, which resulted in 46 unique quality indicators. These were prioritised in round two and ranked in round three by the panel, resulting in a final top ten. The top three indicators were: "shared vision of care for PSS/FD", "pathways tailored to the individual patient", and "sufficiently-experienced caregivers for PSS/FD".CONCLUSIONS: The identified quality indicators to evaluate CCNs in the field of PSS/FD can be implemented in clinical practice and may be useful in improving services and when assessing effectiveness.</p

The Frail Depressed Patient:A Narrative Review on Treatment

Although the public importance of frailty is widely acknowledged by the World Health Organization, physical frailty is still largely neglected in geriatric mental health care. Firstly in this narrative review, we summarize the knowledge on the epidemiology of the association between depression and frailty, whereafter implications for treatment will be discussed. Even though frailty and depression have overlapping diagnostic criteria, epidemiological studies provide evidence for distinct constructs which are bidirectionally associated. Among depressed patients, frailty has predictive validity being associated with increased mortality rates and an exponentially higher fall risk due to antidepressants. Nonetheless, guidelines on the treatment of depression neither consider frailty for risk stratification nor for treatment selection. We argue that frailty assessment enables clinicians to better target the pharmacological and psychological treatment of depression as well as the need for interventions targeting primarily frailty, for instance, lifestyle interventions and reduction of poly -pharmacy. Applying a frailty informed framework of depression treatment studies included in a meta-analysis reveals that the benefit???harm ratio of antidepressants given to frail depressed patients can be questioned. Nonetheless, frail-depressed patients should not withhold antidepressants as formal studies are not available yet, but potential adverse effects should be closely monitored. Dopaminergic anti-depressants might be preferable when slowness is a prominent clinical feature. Psychotherapy is an important alternative for pharmacolo-gical treatment, especially psychotherapeutic approaches within the movement of positive psychology, but this approach needs further study. Finally, geriatric rehabilitation, including physical exercise and nutritional advice, should also be considered. In this regard, targeting ageing -related abnormalities underlying frailty that may also be involved in late-life depression such as low-grade inflammation might be a promising target for future studies. The lack of treatment studies precludes firm recommendations, but more awareness for frailty in mental health care will open a plethora of alternative treatment options to be considered

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

Item does not contain fulltextOBJECTIVE: Research on health-related quality of life (HRQoL) in older persons with medically unexplained symptoms (MUS) is scarce, and, in contrast with younger patients, interactions with chronic somatic diseases are more complex. DESIGN: In the current study we compared HRQoL between older persons with MUS and older persons with medically explained symptoms (MES). Our study sample consisted of 118 older MUS-patients and 154 older MES-patients. SETTING/MEASUREMENTS: The diagnosis of MUS was ascertained by the general practitioner and confirmed by a geriatrician within a multidisciplinary diagnostic assessment. Additional characteristics, including the HRQoL (Short Form-36), were assessed during a home visit. MES-patients received two home visits to assess all measures. Multiple linear regression analyses, adjusted for age, sex, education, cognitive functioning, and psychiatric diagnoses, were performed to assess the relationship between group (MUS/MES) and HRQoL. Analyses were repeated with additional adjustments for somatization and hypochondriacal cognitions. RESULTS: Older patients with MUS had a significantly lower level of HRQoL compared with older patients with MES. Even after adjustments, the presence of MUS was still associated with both a lower physical and mental HRQoL. These associations disappeared, however, after additional adjustments for somatization and hypochondriacal cognitions. Within the subgroup of MUS-patients, higher levels of hypochondriac anxiety and of somatization were significantly associated with both lower physical and mental HRQoL. CONCLUSIONS: Associations between HRQoL and late-life MUS disappear when corrected for somatization and hypochondriacal cognitions, which is in line with the DSM-5 classification of somatic symptom disorder. Appropriate psychological treatment seems needed to improve HRQoL in older MUS-patients

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

BACKGROUND: Research in younger patients with medically unexplained symptoms (MUS) has shown impairments in social functioning, such as loneliness and a reduced quality of the patient-doctor relationship. As far as we know, no studies have been performed on social functioning in older MUS patients; self-reported care needs of older MUS patients remain unknown. OBJECTIVE: To explore social characteristics and care needs of older persons with chronic MUS, when compared to older persons with chronic medically explained symptoms (MES). METHODS: Patient characteristics of 107 older persons (>60 years) with chronic MUS were compared to 150 older persons with chronic MES in a case-control design. Participants were recruited via advertisements, general practices and a specialized clinic. All participants completed questionnaires on social functioning; the Camberwell Assessment of Need for the Elderly was used to draw up care needs. Linear regression analyses were performed to explore the association between social characteristics and group (MUS/MES), adjusted for demographic and physical determinants. Multiple chi-square tests were performed to detect between-group differences regarding care needs. RESULTS: After adjustments, older MUS patients were slightly but significantly lonelier, reported a somewhat lower quality of their patient-doctor relationship, but reported equal social support levels when compared to MES patients. MUS patients more often reported unmet care needs regarding health and information provision about their health status. CONCLUSION: Only small differences in social functioning were found between older MUS and MES patients. Possibly, training future doctors in giving acceptable explanations for the patient's complaints could improve the unmet care need of information provision in older MUS patients

Development of Grip self-help:An online patient-tailored self-help intervention for functional somatic symptoms in primary care

Functional Somatic Symptoms (FSS) are somatic symptoms for which no somatic cause can be identified despite adequate diagnostic testing. FSS are common, costly, and disabling, and treatment options are limited. Psychotherapy is one of few evidence-based treatments for FSS. Yet, this form of therapy is not widely used, since it is usually reserved for severe symptoms, requires a highly trained therapist, and is not well accepted by patients. The current paper describes the development of the online intervention 'Grip self-help' and provides a description of the intervention itself. Grip self-help is an early intervention for mild to moderate FSS in primary care, which aims to reduce somatic symptoms and improve quality of life. In the Grip self-help intervention, patients fill out a set of online questionnaires exploring unhelpful cognitions, emotions, behaviors, and social factors associated with the symptoms. Using this information, a personal profile is generated, identifying factors that might maintain FSS in that individual. As a next step, patients are offered online self-help exercises that are tailored to these factors. Guidance is offered by a primary care professional. The intervention will ultimately result in a personalized self-help guide, composed of texts that are extracted from the exercises patients found useful during the intervention. Grip self-help is the first intervention for FSS combining the concepts of e-health, self-help, and personalized medicine. Guided by a primary care professional, patients are offered an easily accessible, yet highly personalized treatment. Grip self-help thus has the potential to meet the needs of the large group of patients with mild to moderate FSS
