Background antipsychotic drugs are regularly prescribed as first-line treatment for neuropsychiatric symptoms in persons with dementia although guidelines clearly prioritise non-pharmacological interventions. Objective we investigated a person-centred care approach, which has been successfully evaluated in nursing homes in the UK, and adapted it to German conditions. Design a 2-armed 12-month cluster-randomised controlled trial. Setting nursing homes in East, North and West Germany. Methods all prescribing physicians from both study arms received medication reviews for individual patients and were offered access to 2 h of continuing medical education. Nursing homes in the intervention group received educational interventions on person-centred care and a continuous supervision programme. Primary outcome: proportion of residents receiving at least one antipsychotic prescription after 12 months of follow-up. Secondary outcomes: quality of life, agitated behaviour, falls and fall-related medical attention, a health economics evaluation and a process evaluation. Results the study was conducted in 37 nursing homes with n = 1,153 residents (intervention group: n = 493; control group: n = 660). The proportion of residents with at least one antipsychotic medication changed after 12 months from 44.6% to 44.8% in the intervention group and from 39.8 to 33.3% in the control group. After 12 months, the difference in the prevalence was 11.4% between the intervention and control groups (95% confidence interval: 0.9–21.9; P = 0.033); odds ratio: 1.621 (95% confidence interval: 1.038–2.532). Conclusions the implementation of a proven person-centred care approach adapted to national conditions did not reduce antipsychotic prescriptions in German nursing homes.

Minimal scan times in rapid fluorine-19 MRI using sulfur hexafluoride (SF 6 ) have been on the order of 10 s. Because of the very short T 1 relaxation time of SF 6 (T 1 ‫؍‬ 1.65 ms), high receiver bandwidths are necessary to allow for a high number of excitations. Since high bandwidths cause high levels of electronic noise, SNR per acquisition has been too low to further reduce scan time. The purpose of this study was to investigate whether scan times could be reduced using hexafluoroethane (C 2 F 6 ), a gas with a longer T 1 (T 1 ‫؍‬ 7.9 ms) at a relatively low bandwidth of 488 Hz/pixel. Gradient-echo images were acquired during and after completion of the wash-in of a 70% C 2 F 6-30% O 2 mixture. Peak SNR values of 16 and 7.9 were observed for coronal projection images acquired within 2 s and 260 ms, respectively. These results demonstrate that subsecond imaging is feasible using C 2 F 6 .

Risk factors for oropharyngeal dysphagia (OD) in elderly patients are mainly central nervous system (CNS) and structural organic diseases or presbyphagia. We analysed the OD prevalence and association of OD with multimorbidity and polypharmacy using real-life data to complete this spectrum, with a focus on further and iatrogenic risk. This was a cross-sectional retrospective study based on a random sample of 200 patients admitted to a geriatric hospital. Data analysis included diagnoses, the detailed list of drugs, and an intense clinical investigation of swallowing according to Stanschus to screen for OD in each patient. The mean patient age was 84 ± 6.5 years. The prevalence of OD was 29.0%, without an effect of age, but a higher rate was found in men and in nursing home residents and an elevated risk of pneumonia. OD risk was slight in diabetes mellitus and COPD, and pronounced in CNS diseases. A relevant OD association was found, even after adjusting for CNS diseases, with antipsychotics, benzodiazepines, anti-Parkinson drugs, antidepressants, and antiepileptics. Further risk of OD was found with beta-blockers, alpha-blockers, opioids, antiemetics, antivertiginosa or antihistamines, metoclopramide, domperidone, anticholinergics, loop diuretics, urologics, and ophthalmics. From real-life data in patients with and without CNS diseases, we identified drug groups associated with a risk of aggravating/inducing OD. Restrictive indications for these drugs may be a preventative contribution, requiring implementation in dysphagia guidelines and an integrative dysphagia risk scale that considers all associated and cumulative medication risks in addition to diseases.

BackgroundThe majority of nursing home residents with dementia experience behavioural and psychological symptoms like apathy, agitation, and anxiety. According to analyses of prescription prevalence in Germany, antipsychotic drugs are regularly prescribed as first-line treatment of neuropsychiatric symptoms in persons with dementia, although guidelines clearly prioritise non-pharmacological interventions. Frequently, antipsychotic drugs are prescribed for inappropriate reasons and for too long without regular reviewing. The use of antipsychotics is associated with adverse events like increased risk of falling, stroke, and mortality. The aim of the study is to investigate whether a person-centred care approach, successfully evaluated in nursing homes in the United Kingdom, can be implemented in German nursing homes and, in comparison with a control group, can result in a clinically relevant reduction of the proportion of residents with antipsychotic prescriptions.Methods/designThe study is a cluster-randomised controlled trial comparing an intervention group (two-day initial training on person-centred care and ongoing training and support programme) with a control group. Both study groups will receive, as optimised usual care, a medication review by an experienced psychiatrist/geriatrician providing feedback to the prescribing physician. Overall, 36 nursing homes in East, North, and West Germany will be randomised. The primary outcome is the proportion of residents receiving at least one antipsychotic prescription (long-term medication) after 12 months of follow-up. Secondary outcomes are residents’ quality of life, agitated behaviour, as well as safety parameters like falls and fall-related medical attention. A health economic evaluation and a process evaluation will be performed alongside the study.DiscussionTo improve care, a reduction of the current high prescription rate of antipsychotics in nursing homes by the intervention programme is expected.Trial registrationClinicalTrials.gov: NCT02295462Electronic supplementary materialThe online version of this article (doi:10.1186/s13012-015-0268-3) contains supplementary material, which is available to authorized users.
