[Health companion : Findings from the testing of a new volunteering profile]

BACKGROUND

For many (older) people, especially those with chronic diseases, it is a challenge to maintain or develop a health-promoting lifestyle. Knowledge and possibilities of organizing one's own everyday life accordingly are distributed in a socially unequal way; loss of mobility and lack of support and a diluted supply structure in rural areas are further obstacles. As part of the development of a model health center in a rural neighborhood, an approach to health support based on voluntary work was developed and tested, in which volunteers (n = 10) were appointed as peers.

OBJECTIVE

This article describes the theoretical embedding, the conceptual framework of the training (participative learning) and the volunteering profile (outreach support) as well as the effects achieved. On the basis of project experiences and selected evaluation results both beneficial factors as well as challenges were identified. These have to be considered in the further development of the volunteering profile and its implementation in the practice.

MATERIAL AND METHODS

For the evaluation a mixed methods design was applied at two measurement points. In the surveys 14 accompanied persons were included. The qualitative data were analyzed by qualitative content analysis according to Mayring and the quantitative data by descriptive statistics.

RESULTS

The results show that chronically ill (older) people are reached by the voluntary health companion (eGb). The outreach support has positive effects on the receivers and leads to concrete changes in behavior.

CONCLUSION

For the further development, dissemination and consolidation of the eGb, various challenges need to be addressed and adjustments are necessary.

A Network-Wide Stroke Team Program Reduces Time to Treatment for Endovascular Stroke Therapy in a Regional Stroke-Network

BACKGROUND AND PURPOSE

Driven by the positive results of randomized, controlled trials of endovascular stroke therapies (EVT) in stroke patients with large vessel occlusion, different approaches to speed up the workflow for EVT candidates are currently being implemented worldwide. We aimed to assess the effect of a simple stroke network-wide workflow improvement project, primarily focusing on i.v. thrombolysis, on process times for patients undergoing EVT.

METHODS

In 2015, we conducted a network-wide, peer-to-peer acute stroke workflow improvement program for i.v. thrombolysis with the main components of implementing a binding team-based algorithm at every stroke unit of the regional network, educating all stroke teams about non-technical skills and providing a stroke-specific simulation training. Before and after the intervention we recorded periprocedural process times, including patients undergoing EVT at the 3 EVT-capable centers (January - June 2015, n = 80 vs. July 2015 - June 2016, n = 184).

RESULTS

In this multi-centric evaluation of 268 patients receiving EVT, we observed a relevant shortening of the median time from symptom onset to EVT specifically in patients requiring secondary transfer by almost an hour (300 min, 25-75% interquartile range [IQR] 231-381 min to 254 min, IQR 215.25-341 min; p = 0.117), including a reduction of the median door-to-groin time at the EVT-capable center in this patient group by 15.5 min (59 min, IQR 35-102 min to 43.5 min, IQR 27.75-81.25 min; p = 0.063). In patients directly admitted to an EVT-capable center, the median door-to-groin interval was reduced by 10.5 min (125 min, IQR 83.5-170.5 min to 114.5 min, IQR 66.5-151 min; p = 0.167), but a considerable heterogeneity between the centers was observed (p < 0.001).

CONCLUSIONS

We show that a simple network-wide workflow improvement program primarily directed at fast i.v. thrombolysis also accelerates process times for EVT candidates and is a promising measure to improve the performance of an entire stroke network.

Implementation of stroke teams and simulation training shortened process times in a regional stroke network-A network-wide prospective trial

Background

To meet the requirements imposed by the time-dependency of acute stroke therapies, it is necessary 1) to initiate structural and cultural changes in the breadth of stroke-ready hospitals and 2) to find new ways to train the personnel treating patients with acute stroke. We aimed to implement and validate a composite intervention of a stroke team algorithm and simulation-based stroke team training as an effective quality initiative in our regional interdisciplinary neurovascular network consisting of 7 stroke units.

Methods

We recorded door-to-needle times of all consecutive stroke patients receiving thrombolysis at seven stroke units for 3 months before and after a 2 month intervention which included setting up a team-based stroke workflow at each stroke unit, a train-the-trainer seminar for stroke team simulation training and a stroke team simulation training session at each hospital as well as a recommendation to take up regular stroke team trainings.

Results

The intervention reduced the network-wide median door-to-needle time by 12 minutes from 43,0 (IQR 29,8–60,0, n = 122) to 31,0 (IQR 24,0–42,0, n = 112) minutes (p < 0.001) and substantially increased the share of patients receiving thrombolysis within 30 minutes of hospital arrival from 41.5% to 59.6% (p < 0.001). Stroke team training participants stated a significant increase in knowledge on the topic of acute stroke care and in the perception of patient safety. The overall course concept was regarded as highly useful by most participants from different professional backgrounds.

Conclusions

The composite intervention of a binding team-based algorithm and stroke team simulation training showed to be well-transferable in our regional stroke network. We provide suggestions and materials for similar campaigns in other stroke networks.

Social/economic costs and health-related quality of life in patients with juvenile idiopathic arthritis in Europe

OBJECTIVE

The aim of this study was to determine the economic burden from a societal perspective and the health-related quality of life (HRQOL) of patients with juvenile idiopathic arthritis (JIA) in Europe.

METHODS

We conducted a cross-sectional study of patients with JIA from Germany, Italy, Spain, France, the United Kingdom, Bulgaria, and Sweden. Data on demographic characteristics, healthcare resource utilization, informal care, labor productivity losses, and HRQOL were collected from the questionnaires completed by patients or their caregivers. HRQOL was measured with the EuroQol 5-domain (EQ-5D-5L) questionnaire.

RESULTS

A total of 162 patients (67 Germany, 34 Sweden, 33 Italy, 23 United Kingdom, 4 France, and 1 Bulgaria) completed the questionnaire. Excluding Bulgarian results, due to small sample size, country-specific annual health care costs ranged from €18,913 to €36,396 (reference year: 2012). Estimated direct healthcare costs ranged from €11,068 to €22,138; direct non-healthcare costs ranged from €7837 to €14,155 and labor productivity losses ranged from €0 to €8715. Costs are also shown to differ between children and adults. The mean EQ-5D index score for JIA patients was estimated at between 0.44 and 0.88, and the mean EQ-5D visual analogue scale score was estimated at between 62 and 79.

CONCLUSIONS

JIA patients incur considerable societal costs and experience substantial deterioration in HRQOL in some countries. Compared with previous studies, our results show a remarkable increase in annual healthcare costs for JIA patients. Reasons for the increase are the inclusion of non-professional caregiver costs, a wider use of biologics, and longer hospital stays.

[Cost of Illness of HIV Patients under Anteretroviral Therapy in Germany - Results of the 48-Week Interim Analysis of the Prospective Multicentre Observational Study 'CORSAR']

BACKGROUND

With the introduction of highly active combined antiretroviral therapy (c-ART) mortality and morbidity of HIV patients declined substantially. Earlier studies reported that c-ART was able to save health-care costs due to a reduction of other direct medical costs, particularly for inpatient treatments and concomitant medication. To date, analyses of costs and health-related quality of life (HRQOL) of patients under c-ART are lacking in Germany. Hence, this study aims to estimate the current cost of illness and HRQOL of HIV-patients under c-ART in different treatment lines.

METHODS

A multicenter, prospective observational study was carried out in 12 specialised German centres for infectious diseases: 8 private practices/outpatient centres and 4 specialised hospitals offering both inpatient and outpatient services. Demographic, clinical and medication data were derived from patient records. Resource utilisation, information on productivity, out of pocket costs and HRQOL (EQ-5D) were collected every 12 weeks via a patient questionnaire. All costs were calculated based on price information from publicly accessible databases.

RESULTS

N=1,154 patients were included in the analysis. Mean direct disease-related costs of -patients under c-ART amounted to 22,563 Euro/year. Patients beyond the 3(rd) line of treatment -incurred considerably higher costs 24,654 Euro/year. In the 1(st) treatment line, c-ART accounted for 83.2% of the total direct costs, in the 2(nd)/3(rd) line for 80.8% and in >3(rd) line for 83.4%, respectively. Indirect costs due to impaired productivity were higher in the 2(nd)/3(rd) treatment line (2,843 Euro) compared to the 1(st) (1,604 Euro) and >3(rd) (1,752 Euro) treatment lines, respectively. The average HRQOL (EQ-5D) varied between 0.77 (self-assessment via visual analogue scale) and 0.91 (utility score based on the German time trade-off tariff).

CONCLUSIONS

Over the last decade, cost of illness of HIV patients under c-ART decreased slightly with average costs per year still being substantial. Main cost driver of overall costs is c-ART. There have been, however, noticeable shifts between different cost domains.

Morphometric differences in central stress-regulating structures between women with and without borderline personality disorder

BACKGROUND

Experiences of early life stress, increased psychological arousal and the body's physiologic stress response seem to play an important role in the pathogenesis and maintenance of borderline personality disorder (BPD). In the present study, we investigated alterations in grey matter of central stress-regulating structures in female patients with BPD.

METHODS

We examined T1-weighted structural magnetic resonance imaging scans of unmedicated, right-handed female patients with BPD (according to DSM-IV criteria) and healthy controls matched for age, intelligence and education using fully automated DARTEL voxel-based morphometry. Our regions of interest analyses included the hippocampus, amygdala, anterior cingulate cortex (ACC) and hypothalamus.

RESULTS

We enrolled 30 patients and 33 controls in our study. The grey matter of patients with BPD was reduced in the hippocampus, but increased in the hypothalamus compared with healthy participants. Hypothalamic volume correlated positively with the history of traumatization in patients with BPD. No significant alterations were found in the amygdala and ACC.

LIMITATIONS

This study is limited by the lack of measures of corticotropin-releasing hormone, adrenocorticotropic hormone and cortisol levels. Furthermore, moderate sample size and comorbid disorders need to be considered.

CONCLUSION

Our findings provide new evidence for grey matter alterations in the hypothalamus and replicate previously reported decrements in hippocampal volume in patients with BPD. Understanding the role of the hypothalamus and other central stress-regulating structures could help us to further understand the neurobiological underpinnings of this complex disorder.

Patient satisfaction and quality of life in cancer outpatients: results of the PASQOC study

BACKGROUND

Satisfaction with care and quality of life (QoL) are indicative of the quality of care of cancer patients. The purpose of this study was to lay a cornerstone for patient-centred quality management by assessing the current status of satisfaction with care and QoL among oncological outpatients in Germany, and by identifying the key factors that determine a patient's willingness to recommend a medical facility.

PATIENTS AND METHODS

A self-constructed and validated patient satisfaction questionnaire plus the SF-36 were distributed to a random sample of 3384 cancer patients who presented at 24 investigators' offices nationwide within a defined recruiting period and who met the inclusion criteria. The return rate was 81.9% (n=2772). A total of 2659 (78.6%) questionnaires were evaluable. The most common cancer types were breast (22.9%) and intestine (19.8%).

RESULTS

Overall satisfaction was high, but specific reporting questions revealed many areas for improvement such as shared decision making, doctor-patient communication and organization of care. QoL was significantly impaired in many domains. Patient-provider relationship, facility setting and information on diagnosis and treatment options are major determinants of a patient's willingness to recommend a facility to a friend or relative if needed.

CONCLUSIONS

This multicentre study focusing on patient perspectives highlights that, although the overall degree of satisfaction was quite high, there are numerous areas for improvement.

Longitudinal study examining the neurotoxicity of occupational exposure to aluminium-containing welding fumes

OBJECTIVES

The neurotoxicity of occupational exposure to aluminium (Al)-containing welding fumes has been discussed with controversial results. The aim of the longitudinal study was to examine a group of Al welders for significant central nervous changes in comparison with a non-exposed cohort.

METHODS

A group of 98 Al welders (mean age 37 years) in the car-body construction industry, with a median of 6 years of occupational exposure to Al welding fumes, and an education-matched, gender-matched, age-matched control group of 50 car-production workers (mean age 36 years) at the same plant, were included in this longitudinal study. Two cross-sectional studies were done in 1999 and 2001. In the second cross-sectional study 97 welders and 50 controls could be examined. The examination programme consisted, for example, of a standardised anamnesis, focussing on occupational history, education, illnesses, medication, accidents and current alcohol consumption, a physical examination that included neurological status, and the assessment of Al concentration in plasma and urine. The neurobehavioral methods included a symptom questionnaire, modified Q16, and computerised and non-computerised tests: psychomotor performance (steadiness, line tracing, aiming, tapping), verbal intelligence (WST), simple reaction time, digit span, block design (HAWIE), symbol-digit substitution, digit span, switching attention (European neurobehavioral evaluation system, EURO-NES), and standard progressive matrices. The data were analysed by multivariate analysis of covariance (MANCOVA) for repeated measurements with covariates age, education, and carbohydrate-deficient transferrin in plasma (CDT). RESULTS. The median Al urine concentration (mean preshift/postshift) was 52.4 microg/g creatinine (2001) and 57.6 microg/g creatinine (1999). Median respirable air dust was 0.67 mg/m(3) (2001) and 0.47 mg/m(3) (1999). Welders and controls did not report significantly more symptoms in the modified Q16. Furthermore, no significant differences in psychomotor performance and other neurobehavioral tasks, except for reaction time, were seen between welders and non-welders. Regression analyses reveal a significant relationship between reaction time and Al excretion in urine that was confounded by other factors.

CONCLUSIONS

At present the outcome for reaction time has to be interpreted as a single result. However, as the modified Q16 questionnaire and the rest of the psychomotor performance showed no significant changes, the next cross-sectional study, in 2003, will provide further information on which a final conclusion can be based.

ACE-inhibitors but not endothelin receptor blockers prevent podocyte loss in early diabetic nephropathy

AIMS/HYPOTHESIS

It was the aim of our study to investigate the influence of a selective ET-A receptor antagonist LU 135252 alone and in combination with the ACE-inhibitor, trandolapril on podocyte number and morphology in streptozotocin diabetic rats.

METHODS

Male Sprague-Dawley rats were injected with 65 mg streptozotocin i.v. and subsequently developed diabetes. Animals were left untreated or received daily either trandolapril (0.3 mg/kg body weight), LU 135252 (50 mg/kg body weight) or a combination of both. After 6 months the experiment was terminated. Glomerular geometry and cellularity were assessed by stereological techniques. Protein expression of TGF-beta, ET-1, PDGF-AB, fibronectin, desmin and alpha-smooth muscle cell actin was investigated by immunohistochemistry.

RESULTS

The mean number of podocytes per glomerulus was lower (86+/-17 vs. 138+/-25; p<0.05) and mean podocyte volume was higher in untreated diabetic animals than in non-diabetic controls. Only ACE-i alone and in combination, but not ET(A)-RB alone prevented loss of podocytes and podocyte hypertrophy. In diabetic rats, increased numbers of PCNA positive and p27(kip1) positive cells (mainly podocytes) were reduced by all treatments, but only ACE-i decreased numbers of desmin positive podocytes and tubulointerstitial expression of TGF-beta. Albuminuria was increased in untreated diabetes and was prevented only by ACE-i and combination treatment.

CONCLUSION/INTERPRETATION

Podocyte hypertrophy and degeneration is an early event in diabetic nephropathy leading to a loss of podocytes. Treatment with an ACE-i, but not with an ET(A)-RB, prevented the development of albuminuria as well as damage and loss of podocytes. The well known anti-proteinuric effect of ACE-i is presumably due at least in part to conservation of podocyte structure. Increased plasma endothelin-1 (ET-1) concentrations and urine excretion of ET-1 have been documented in patients with diabetes and proteinuria [1]. It has been shown that experimental diabetes mellitus increases renal ET-1 gene transcription [2]. To assess the relevance of the ET-system in the pathogenesis of renal structural changes in the model of the STZ-induced diabetic rat we compared the effect of an ET(A)-receptor specific antagonist with the well known beneficial effect of an ACE-i, especially on podocyte cell number and morphology.

Genotype, phenotype, and protein structure in a regulator of sporulation: effects of mutations in the spoIIAA gene of Bacillus subtilis

SpoIIAA, a phosphorylatable protein, is essential to the regulation of sigmaF, the first sporulation-specific transcription factor of Bacillus subtilis. The solution structure of SpoIIAA has recently been published. Here we examine four mutant SpoIIAA proteins and correlate their properties with the phenotypes of the corresponding B. subtilis mutant strains. Two of the mutations severely disrupted the structure of the protein, a third greatly diminished the rate of its phosphorylation and abolished dephosphorylation, and the fourth left phosphorylation unaffected but reduced the rate of dephosphorylation about 10-fold.

[Psychology of the physically handicapped patient--an outline of development in Germany]

The present article is directed at giving a broad account of the emergence and subsequent differentiation of a specific "psychology of the physically disabled" in Germany, based on articles by selected authors, that appeared in "Zeitschrift für Krüppelfürsorge" (1909-1943) and "Jahrbücher der Fürsorge für Körperbehinderte" (1951-1962). With the cripple care sector just beginning to organize itself around the turn of the century, a historical-chronologically oriented overview is given of those psychological currents that have made decisive contributions toward shaping today's understanding of rehabilitation. Essential positions are brought out, with core ideas presented by original quotations. It turns out in this process that many of our contemporary ideas, which are deemed so modern and novel, have in fact originated already in the first half of the century.

[Comparison of the values of automatic ECG analysis according to the Smith and the Pipberger diagnostic programs by means of a serial study in a large industry]

It could be shown that an ECG-screening could be integrated into the routine work of a factory outpatient department. As a result of the automatical analysis of the ECG we got an exact knowledge of the efficiency of Smith's and Pipberger's diagnostic programmes. The suitability of the two programmes for screening examinations resulted from the 91% and 97% certain separation of normal and pathological findings and the small proportion of falsely negative results (Smith, Pipberger). Concerning the exact differentiation of pathological ECG the frequency of recognition of Pipberger's programme still surpassed that one of Smith's programme. However, the two programmes show a diagnostic security which lies above the visual diagnosing. The establishment of findings performed off line per week ascertained a rapid disposal of results. In comparison to former examinations newly detected cases could be established only in a small percentage. The importance for health polities of such examinations results from the necessity of the prophylaxis of cardio-vascular diseases, the numbers of morbidity and mortality of which are permanently increasing.

[Experience in the use of Smith's ECG evaluation program]

After the experiences with the use of the programme of Pipberger concerning the automatised ECG-analysis in clinic, outpatient department and factory public health, which were made at the Medical Academy Erfurt during the last years, at this time comparative examinations with the ECG-analysis programme of Smith were performed. The intake of data (3 orthogonal leads) is done by means of a data establishing unit developed by us. For the analog-digital-changing, the pretreatment of data and the transmission of the ECG-data on the digital magnet tape a process-calculator TPA-i is used. The analysis is performed by the computer Robotron 21. The evaluation of the results shows that, when a great number of patients is examined, normal curves are correctly estimated at 100%. The recognition rate of pathological curves has with 79.5% about the same size as the visual judgment. The deficiencies of the diagnostic programme of Smith must be essentially found in the relatively high proportion of falsely negative findings, the insufficient differentiation of the changes of the chamber variation, in the sometimes incorrect formation, why the classification of the curves in individual groups was performed. On account of the certain centage of falsely negative ones the programme is well recognition of normal findings and the tolerable pernotion of the diagnosis and the sometimes lacking insuited for screening examinations.
