Collaboration applications for mixed home care - A systematic review of evaluations and outcomes.

OBJECTIVES: Mixed home care, in which informal and professional actors work closely together, contributes significantly to ensuring home care up to old age. In this context, collaboration applications can considerably enhance the interactions among caregivers. However, although much research is conducted on need and requirement analyses of such applications, little is known about their introduction and use in care models. The purpose of this contribution is to identify studies that evaluate collaboration applications for mixed home care and compare their outcomes. METHODS: To identify literature on mixed home care collaboration applications (mHCA) and their evaluation, a systematic literature review was conducted in five bibliographic databases covering the years 2008 through 2019. The results were supplemented by a search in the meta-database Google Scholar. The evaluation approaches of the studies were analyzed and results compared by using the NASSS framework. Finally, a context concretized model was derived which summarizes interrelations. RESULTS: Twelve qualitative studies evaluating eleven applications could be identified. They report on increased competency in self-management, psychological relatedness, involvement, and understanding. However, most studies conclude that large scale platform tests are still needed to prove significant changes in care processes, communication, or organization. CONCLUSION: Among other things, their implementation is rather difficult due to the specifics of the target group. To enable a more targeted and successful implementation, it might be helpful to classify care networks beforehand and assess their communication behavior and needs. To prove the added value of mHCAs standardized assessment tools should be used.

Transcranial Pulse Stimulation with Ultrasound in Alzheimer's Disease-A New Navigated Focal Brain Therapy.

Ultrasound-based brain stimulation techniques may become a powerful new technique to modulate the human brain in a focal and targeted manner. However, for clinical brain stimulation no certified systems exist and the current techniques have to be further developed. Here, a clinical sonication technique is introduced, based on single ultrashort ultrasound pulses (transcranial pulse stimulation, TPS) which markedly differs from existing focused ultrasound techniques. In addition, a first clinical study using ultrasound brain stimulation and first observations of long term effects are presented. Comprehensive feasibility, safety, and efficacy data are provided. They consist of simulation data, laboratory measurements with rat and human skulls and brains, in vivo modulations of somatosensory evoked potentials (SEP) in healthy subjects (sham controlled) and clinical pilot data in 35 patients with Alzheimer's disease acquired in a multicenter setting (including neuropsychological scores and functional magnetic resonance imaging (fMRI)). Preclinical results show large safety margins and dose dependent neuromodulation. Patient investigations reveal high treatment tolerability and no major side effects. Neuropsychological scores improve significantly after TPS treatment and improvement lasts up to three months and correlates with an upregulation of the memory network (fMRI data). The results encourage broad neuroscientific application and translation of the method to clinical therapy and randomized sham-controlled clinical studies.
