[Development of an indicator set for the evaluation of the quality of routine ambulatory health care for common disorders in children and adolescents]

BACKGROUND

In Germany, no consented quality indicator set (QI set) exists to date that can be used to assess the quality of pediatric care. Therefore, the aim of the project "Assessment of the quality of routine ambulatory health care for common disorders in children and adolescents" (QualiPäd) funded by the Innovation Committee of the Federal Joint Committee (grant no.: 01VSF19035) was to develop a QI set for the diseases asthma, atopic eczema, otitis media, tonsillitis, attention-deficit hyperactivity disorder (ADHD), depression and conduct disorder.

METHODS

For the observation period 2018/2019, quality indicators (QIs) were searched in indicator databases, guidelines and literature databases and complemented in part by newly formulated QIs (e.g., derived from guideline recommendations). The QIs were then assigned to content categories and dimensions according to Donabedian and OECD and reduced by removing duplicates. Finally, a panel of experts consulted the QIs using the modified RAND-UCLA Appropriateness Method (RAM).

RESULTS

The search resulted in a preliminary QI set of 2324 QIs. After the reduction steps and the evaluation of the experts, 282 QIs were included in the QI set (asthma: 72 QIs, atopic eczema: 25 QIs, otitis media: 31 QIs, tonsillitis: 12 QIs, ADHD: 53 QIs, depression: 43 QIs, conduct disorder: 46 QIs). The QIs are distributed among the following different categories: Therapy (138 QIs), Diagnostics (95 QIs), Patient-reported outcome measures/Patient-reported experience measures (PROM/PREM) (45 QIs), Practice management (31 QIs), and Health reporting (4 QIs). In the Donabedian model, 89% of the QIs capture process quality, 9% outcome quality, and 2% structural quality; according to the OECD classification, 61% measure effectiveness, 23% patient-centeredness, and 16% safety of care.

CONCLUSION

The consented QI set is currently being tested and can subsequently be used (possibly modified) to measure the quality of routine outpatient care for children and adolescents in Germany, in order to indicate the status quo and potential areas for improvement in outpatient care.

Structural assessment of the gripper interlock of the DEMO breeding blanket transporter

The maintenance of the DEMO Breeding Blanket (BB) remotely is a crucial aspect in development of the DEMO power plant. It is a challenge due to the huge mass of the BB segment of about 180 tons. A new concept for the BB transporter has recently been developed. To properly grip and manipulate each BB segment, the BB transporter has been equipped with a gripper interlock. Due to the geometry of the BB and the vacuum vessel, the attachment point on the BB segment is not aligned with its center of gravity. Hence in addition to the vertical lifting load, large moments about the horizontal axes need to be reacted. The work discussed here concerns the structural analysis conducted on the gripper interlock; its structural integrity has been checked against the most severe load conditions that include also seismic loads according to the EN13001. Elastic analyses were performed using a finite element model in accordance with EN 13001-3-1:2012 + A2:2018, Cranes - General Design - Part 3-1: Limit States and proof competence of steel structure. The effect of the gap sizes at the contact surfaces between gripper interlock and BB after engagement as well as the effect of different friction coefficients on the sliding areas were assessed. The improvements of the design based on the structural analysis are presented, too.

Structural optimisation of the DEMO alternative divertor configurations based on FE and RBF mesh morphing

The DEMO tokamak exhibits extraordinary complexity due to the constraints and requirements pertaining to different fields of physics and engineering. The multidisciplinary nature of the DEMO system makes its design phase extremely challenging since different and often opposite requirements need to be accounted for. Toroidal field (TF) coils generate the toroidal magnetic field required to magnetically confine the plasma particles and support at the same time the poloidal field coils. They must bear tremendous loads deriving from electromagnetic interactions between the coil currents and the generated magnetic field. An efficient tokamak design aims at minimizing the energy stored in its magnetic field and hence at reducing the toroidal volume within the TF coils whose shape would hence ideally mimic co-centrically the shape of the plasma. In order to bear the enormous forces a D-shape is most suitable for the TF coils as it allows them to resist the very large compression on the inner side and to carry the electro-magnetic (EM) pressure mainly by membrane stresses preventing large bending to occur on the outer side. At the same time the divertor structures must fit within the TF coils and this requires adaptations of the TF coil shape in the case of so-called advanced divertor configurations (ADCs), which require larger divertor structures. This article shows the TF coils adapted to ADCs using a structural optimisation procedure applied to the reference shape. The introduced strategy takes as structural optimum the iso-stress profile associated to each coil. A continuous transformation, based on radial basis functions mesh morphing, turns the baseline finite element (FE) model into its iso-stress counterpart, with a series of intermediate configurations available for electromagnetic and structural investigations as output. The adopted strategy allowed to determine, for each of the ADC cases, a candidate shape. Static membrane stress levels during magnetization could be reduced significantly from more than 700 MPa to below 450 MPa.

Process over outcome quality in paediatrics? An analysis of outpatient healthcare quality indicators for seven common diseases

PURPOSE

The purpose of this study was to examine the scope, quality dimensions and treatment aspects covered by existing quality indicators (QIs) for the somatic diseases bronchial asthma, atopic eczema, otitis media and tonsillitis as well as the psychiatric disorders attention deficit hyperactivity disorder (ADHD), depression and conduct disorder in paediatrics.

METHODS

QIs were identified through an analysis of the guidelines and a systematic search of literature and indicator databases. Subsequently, two researchers independently assigned the QIs to the quality dimensions according to Donabedian and Organisation for Economic Cooperation and Development (OECD) and to the content categories covering the treatment process.

RESULTS

We found 1268 QIs for bronchial asthma, 335 QIs for depression, 199 QIs for ADHD, 115 QIs for otitis media, 72 QIs for conduct disorder, 52 QIs for tonsillitis and 50 QIs for atopic eczema. Of these, 78% focused on process quality, 20% on outcome quality and 2% on structural quality. Using OECD criteria, 72% of the QIs were assigned to effectiveness, 17% to patient-centredness, 11% to patient safety and 1% to efficiency. The QIs covered the following categories: diagnostics (30%), therapy (38%), patient-reported outcome measures/ observer-reported outcome measures/patient-reported experience measures (in sum 11%), health monitoring (11%) and office management (11%).

CONCLUSION

Most QIs focused on the dimensions of effectiveness and process quality, and on the categories of diagnostics and therapy, with outcome-focused and patient-focused QIs being under-represented. Possible reasons for this striking imbalance could be the easier measurability and clearer assignment of accountability in comparison to the QIs of outcome quality, patient-centredness and patient safety. To produce a more balanced picture of the quality of healthcare, the future development of QIs should prioritise the currently under-represented dimensions.

Incidence of falls and fall-related injuries and their predictive factors in frail older persons with cancer: a multicenter study

Background

Falls and fall-related injuries are a major public health problem. Data on falls in older persons with cancer is limited and robust data on falls within those with a frailty profile are missing. The aim of this study is to investigate the incidence and predictive factors for falls and fall-related injuries in frail older persons with cancer.

Methods

This study is a secondary data analysis from data previously collected in a large prospective multicenter observational cohort study in older persons with cancer in 22 Belgian hospitals (November 2012–February 2015). Patients ≥70 years with a malignant tumor and a frailty profile based on an abnormal G8 score were included upon treatment decision and evaluated with a Geriatric Assessment (GA). At follow-up, data on falls and fall-related injuries were documented.

Results

At baseline 2141 (37.2%) of 5759 included patients reported at least one fall in the past 12 months, 1427 patients (66.7%) sustained an injury. Fall-related data of 3681 patients were available at follow-up and at least one fall was reported by 769 patients (20.9%) at follow-up, of whom 289 (37.6%) fell more than once and a fall-related injury was reported by 484 patients (62.9%). Fear of falling was reported in 47.4% of the patients at baseline and in 55.6% of the patients at follow-up. In multivariable analysis, sex and falls history in the past 12 months were predictive factors for both falls and fall-related injuries at follow-up. Other predictive factors for falls, were risk for depression, cognitive impairment, dependency in activities of daily living, fear of falling, and use of professional home care.

Conclusion

Given the high number of falls and fall-related injuries and high prevalence of fear of falling, multifactorial falls risk assessment and management programs should be integrated in the care of frail older persons with cancer. Further studies with long-term follow-up, subsequent impact on cancer treatment and interventions for fall prevention, and integration of other important topics like medication and circumstances of a fall, are warranted.

Functional status in older patients with cancer and a frailty risk profile: A multicenter observational study

INTRODUCTION

Functional status (FS) and frailty are significant concerns for older adults, especially those with cancer. Data on FS (Activities of Daily Living [ADL]; Instrumental Activities of Daily Living [IADL]) and its evolution during cancer treatment in older patients and a frailty risk profile are scarce. Therefore, this study examines FS and its evolution in older patients with cancer and a frailty risk profile and investigates characteristics associated with functional decline.

MATERIAL AND METHODS

This secondary data-analysis, focusing on FS, uses data from a large prospective multicenter observational cohort study. Patients ≥70 years with a solid tumor and a frailty risk profile based on the G8 screening tool (score ≤ 14) were included. A geriatric assessment was performed including evaluation of FS based on ADL and IADL. At approximately three months of follow-up, FS was reassessed. Univariable and multivariable logistic regression analyses were used to identify predictive factors for functional decline in ADL and IADL.

RESULTS

Data on ADL and IADL were available at baseline and follow-up in 3388 patients. At baseline 1886 (55.7%) patients were dependent for ADL, whereas 2085 (61.5%) patients were dependent at follow-up. Functional decline was observed in 23.6% of patients. For IADL 2218 (65.5%) patients were dependent for IADL, whereas 2591 (76.5%) patients were dependent at follow-up. Functional decline in IADL was observed in 41.0% of patients. In multivariable analysis, disease stage III or IV, comorbidities, falls history in the past twelve months, and FS measured by IADL were predictive factors for functional decline in both ADL and IADL. Other predictive factors for functional decline in ADL were polypharmacy, Eastern Cooperative Oncology Group-Performance Status (ECOG-PS) score 2-4, and cognitive impairment, and for functional decline in IADL were female sex, fatigue, and risk for depression.

DISCUSSION

Functional impairments are frequent in older persons with cancer and a frailty risk profile, and several characteristics are identified that are significantly associated with functional decline. Therefore, FS is an essential part of the geriatric assessment which should be standard of care for this patient population. Next step is to proceed with directed interventions with the aim to limit the risk of functional decline as much as possible.

Acute endometriosis-related sigmoid perforation in pregnancy- case report

Background

An acute abdomen is an emergency that requires accurate diagnosis and prompt treatment. In pregnancy, the process is even more challenging and sometimes the radiological findings are unclear. Moreover, endometriosis- related complications are rare, especially in previously unknown endometriosis.

Case presentation

We report on a case of acute endometriosis-related sigmoid perforation during pregnancy (34 weeks of gestation) due to a previously unknown deep intestinal infiltrating endometriosis with focal ulceration of the affected colonic mucosa.

Conclusions

Despite the low relative risk, clinicians should be aware of possible endometriosis-associated complications in pregnancy with potentially life-threatening events, even in previously unknown endometriosis. Further studies should evaluate intestinal complications during pregnancy in relation to previous treatment of intestinal endometriosis (conservative vs. surgical).

Health Services Use and Costs in Individuals with Autism Spectrum Disorder in Germany: Results from a Survey in ASD Outpatient Clinics

Introduction

Autism spectrum disorders (ASD) are associated with high services use, but European data on costs are scarce.

Objectives

Utilisation and annual costs of 385 individuals with ASD (aged 4-67 years; 18.2% females; 37.4% IQ < 85) from German outpatient clinics were assessed.

Methods

Client Service Receipt Inventory

Results

Average annual costs per person were 3287 EUR, with psychiatric inpatient care (19.8%), pharmacotherapy (11.1%), and occupational therapy (11.1%) being the largest cost components. Females incurred higher costs than males (4864 EUR vs. 2936 EUR). In a regression model, female sex (Cost Ratio: 1.65), lower IQ (1.90), and Asperger syndrome (1.54) were associated with higher costs.

Conclusions

In conclusion, ASD-related health costs are comparable to those of schizophrenia, thus underlining its public health relevance. Higher costs in females demand further research.

A good investment: longer-term cost savings of sensitive parenting in childhood

Introduction

Good quality parenting in early childhood is reliably associated with positive mental and physical health over the lifespan.

Objectives

The hypothesis that early parenting quality has significant long-term financial benefits has not been previously tested.

Methods

Design: Longitudinal study with follow-up from 2012 to 2016; UK multicentre study cohort. Participants: 174 young people drawn from 2 samples, one at moderate risk of poor outcomes and one at high risk, assessed aged 4–6 years then followed up in early adolescence (mean age 12.1 years). Measures: The primary outcome was total costs: health, social care, extra school support, out-of-home placements and family-born expenditure, determined through semistructured economic interviews. Early parenting quality was independently assessed through direct observation of parent–child interaction.

Results

Costs were lower for youths exposed to more sensitive parenting (most sensitive quartile mean £1,619, least sensitive quartile mean £21,763; p < .001). Costs were spread across personal family expenditure and education, health, social and justice services. The cost difference remained significant after controlling for several potential confounders. These included demographic variables (family poverty, parental education); exposure to child abuse; and child/young person variables including level of antisocial behaviour in both childhood and adolescence, IQ and attachment security.

Conclusions

This study is the first showing that more sensitive early parental care predicts lower costs to society many years later, independent of poverty, child and youth antisocial behaviour levels and IQ. The findings provide novel evidence for the public health impact of early caregiving quality and likely financial benefits of improving it.

Therapeutic drug monitoring of atomoxetine in children and adolescents with attention-deficit/ hyperactivity disorder: a naturalistic study

The selective norepinephrine reuptake inhibitor atomoxetine is potentially among the first-line pharmacotherapy options for ADHD. Therapeutic drug monitoring (TDM) with the quantification and interpretation of atomoxetine serum concentrations is used to determine an individual dose followed by an optimal effectiveness and minimal side effects. The aim of this retrospective pharmacokinetic–pharmacodynamic analysis was to derive age-appropriate recommendations for the implementation of TDM to improve the efficacy and tolerability of atomoxetine in children and adolescents. Using the analytical method of high-performance liquid chromatography with UV detection, 94 serum concentrations of 74 patients between 6 and 21 years of age were determined. Therapeutic effectiveness and side effects were evaluated according to the categories “low”, “moderate”, and “significant”. As part of TDM, a time interval with maximum concentrations of 1–3 h after the administration of atomoxetine was determined for blood sampling. In this time interval, a significant correlation between the weight-normalized dose and the serum concentrations was found. The efficacy as well as the tolerability proved to be mainly moderate or significant. A preliminary therapeutic reference range was between 100 and 400 ng/ml. Naturalistic studies have limitations. Therefore, and due to a limited study population, the results have to be regarded as preliminary observations that must be confirmed in further studies. The preliminary therapeutic reference range for children and adolescents proved to be narrower than the reference range for adult patients. However, due to good efficacy and tolerability an exact reference range remained difficult to determine.

Prevalence of multimodal treatment in children and adolescents with ADHD in Germany: a nationwide study based on health insurance data

BACKGROUND

Attention-deficit hyperactivity disorder (ADHD) ranks top among neurodevelopmental disorders in children and adolescents. Due to a large number of unfavorable outcomes including psychiatric comorbidities, school problems, and lower socioeconomic status, early and effective treatment of ADHD is essential. Multimodal treatment has become the gold standard in ADHD management, comprising pharmacotherapy and psychosocial interventions, e.g., psychotherapy. Yet, little is known about the prevalence of multimodal treatment in routine care.

METHODS

Based on German health claims data for the years 2009-2017, we identified children and adolescents aged 3-17 years diagnosed with ADHD and characterized them cross-sectionally (per calendar year) in terms of treatment status and psychiatric comorbidities. The detection of pharmacotherapy was based on dispensations of drugs to treat ADHD (e.g., methylphenidate); psychotherapeutic treatment was based on corresponding billing codes. Multimodal treatment was assumed if ADHD medication and psychotherapeutic treatment were coded within the same calendar year. Psychiatric comorbidities were based on outpatient and inpatient diagnoses. Prevalences of ADHD and proportions of different treatment options were calculated and standardized by age and sex.

RESULTS

In 2017, 91,118 children met the study criteria for ADHD (prevalence: 42.8/1000). Of these, 25.2% had no psychiatric comorbidity, 28.8% had one, 21.6% had two, and 24.5% had three or more. Regarding overall treatment status, 36.2% were treated only pharmacologically, 6.5% received multimodal treatment, and 6.8% were treated with psychotherapy only (neither treatment: 50.2%). With increasing numbers of psychiatric comorbidities, the proportions of patients with multimodal treatment increased from 2.2% (no psychiatric comorbidities) to 11.1% (three or more psychiatric comorbidities) while the proportions of untreated (from 56.8% to 42.7%) or only pharmacologically treated patients (38.4% to 35.0%) decreased. From 2009 to 2017, prevalences were stable and the proportion of patients with only pharmacotherapy decreased from 48% to 36.5%. Concurrently, the proportion of patients with neither pharmacotherapy nor psychotherapy increased from 40.5% to 50.2%. The fraction of patients with multimodal treatment ranged between 6.5% (2017) and 7.4% (2013).

CONCLUSIONS

Multimodal treatment, although recommended as the standard of treatment, is rather the exception than the rule. It is, however, increasingly common in ADHD patients with psychiatric comorbidities.

[Outpatient Psychological Therapies in Children and Adolescents in Germany: Status Quo and Time Trends, 2009-2018]

OBJECTIVE

To determine the prevalence of outpatient psychological therapies (PT) in youths with statutory health insurance in Germany.

METHODS

Based on statutory health insurance funds data for 2009-2018, the prevalence of outpatient PT was assessed, stratified by sex, age, and federal state. Psychotherapeutic specialty, coded psychiatric diagnoses, and type of PT were also analysed.

RESULTS

In 2018, 7.3 % received any form of PT (2009: 7.1 %). Of these, 18.4 % (2009: 12.8 %) received therapy according to the directives for psychotherapy (dPT), with CBT (since 2012) being most frequently used. PT prevalence was highest in 15- to 19-year olds, and only marginally differed by sex. Child psychiatrists delivered the majority of PTs. Main diagnoses were anxiety/emotional disorders, ADHD, and adjustment disorders.

CONCLUSION

During the studied period, PT prevalence has not changed markedly. Yet, the share of dPT has increased, with CBT ranking top.

Development and national consensus finding on patient-centred high stakes communication skills assessments for the Swiss Federal Licensing Examination in Medicine

OBJECTIVE

To describe and evaluate a consensus finding and expert validation process for the development of patient-centred communication assessments for a national Licensing Exam in Medicine.

METHODS

A multi-professional team of clinicians and experts in communication, assessment and role-play developed communication assessments for the Swiss Federal Licensing Examination. The six-month process, informed by a preceding national needs-assessment, an expert symposium and a critical literature review covered the application of patient-centred communication frameworks, the development of assessment guides, concrete assessments and pilot-tests. The participants evaluated the process.

RESULTS

The multiple-step consensus process, based on expert validation of the medical and communication content, led to six high-stakes patient-centred communication OSCE-assessments. The process evaluation revealed areas of challenge such as calibrating rating-scales and case difficulty to the graduates' competencies and integrating differing opinions. Main success factors were attributed to the outcome-oriented process and the multi-professional exchange of expertise. A model for developing high stakes patient-centred communication OSCE-assessments was derived.

CONCLUSIONS

Consensus finding was facilitated by using well-established communication frameworks, by ensuring outcome-orientated knowledge exchange among multi-professional experts, and collaborative validation of content through experts.

PRACTICE IMPLICATIONS

We propose developing high-stakes communication assessments in a multi-professional expert consensus and provide a conceptual model.

Special educational support in children and adolescents with Autism Spectrum Disorder in Germany: Results from a parent survey

OBJECTIVE

Children and adolescents with Autism Spectrum Disorder (ASD) often receive special educational support (SES). This study aimed to evaluate SES prevalence in children and adolescents with ASD in Germany.

METHODS

A mail survey was distributed to the caregivers of 637 children and adolescents recruited at three German ASD outpatient clinics.

RESULTS

Among the 211 respondents (response: 33.1 %), 82.5 % were provided with a special educational needs statement, and 63.9 % received special education, most of them attending a public special school (57.9 %). The most frequently indicated additional support was a classroom assistant (69.0 %), followed by smaller learning groups (31.7 %). Special education was less frequently provided to individuals with Asperger syndrome than to those with childhood or atypical autism (36.0 %, 76.1 %, and 63.4 %, respectively). Using logistic regression analysis, receiving special education was significantly associated with lower IQ (<85) (Odds Ratio (OR): 8.72; 95 % confidence interval (CI): 3.41-22.32) and younger age (≤11 years, OR: 2.87; 95 % CI: 1.11-7.38), but not with ASD symptom severity.

CONCLUSIONS

The majority of children and adolescents with ASD received SES, indicating a satisfactory supply of such services in Germany. The finding that lower IQ but not ASD symptom severity predicted access to SES raises questions about the specificity of the used selection criteria.

A Millimeter-Scale Crystal-Less MICS Transceiver for Insertable Smart Pills

This paper presents a millimeter-scale crystal-less wireless transceiver for volume-constrained insertable pills. Operating in the 402-405 MHz medical implant communication service (MICS) band, the phase-tracking receiver-based over-the-air carrier recovery has a ±160 ppm coverage. A fully integrated adaptive antenna impedance matching solution is proposed to calibrate the antenna impedance variation inside the body. A tunable matching network (TMN) with single inductor performs impedance matching for both transmitter (TX) and receiver (RX) and TX/RX mode switching. To dynamically calibrate the antenna impedance variation over different locations and diet conditions, a loop-back power detector using self-mixing is adopted, which expands the power contour up to 4.8 VSWR. The transceiver is implemented in a 40-nm CMOS technology, occupying 2 mm² die area. The transceiver chip and a miniature antenna are integrated in a 3.5 × 15 mm² area prototype wireless module. It has a receiver sensitivity of -90 dBm at 200 kbps data rate and delivers up to - 25 dBm EIRP in the wireless measurement with a liquid phantom.

Unplanned hospitalizations in older patients with cancer: Occurrence and predictive factors

BACKGROUND

This study aims to investigate the occurrence of unplanned hospitalizations in older patients with cancer and to determine predictive factors.

METHODS

A prospective Belgian multicentre (n = 22), observational cohort study was performed. Patients ≥70 years with a malignant tumor were included. Patients underwent G8 screening followed by geriatric assessment (GA) if abnormal at baseline and were followed for unplanned hospitalizations at approximately three months. Uni- and multivariable regression models were performed to determine predictive factors associated with unplanned hospitalizations in older patients with an abnormal G8.

RESULTS

In total, 7763 patients were included in the current analysis of which 2409 (31%) patients with a normal G8 score and 5354 (69%) with an abnormal G8 score. Patients with an abnormal G8 were hospitalized more frequently than patients with a normal G8 (22.9% versus 12.4%; p < 0.0001). Reasons for unplanned hospitalizations were most frequently cancer related (25.7%) or cancer therapy related (28%). In multivariable analysis, predictive factors for unplanned hospitalizations in older patients with cancer and an abnormal G8 were female gender, absence of surgery, chemotherapy, ADL dependency, malnutrition and presence of comorbidities.

CONCLUSION

Older patients with cancer and an abnormal G8 screening present a higher risk (23%) for unplanned hospitalizations. Predictive factors for these patients were identified and include not only patient and treatment related factors but also GA related factors.
