IntroductionIntermittent hypoxic–hyperoxic training (IHHT) may complement a multimodal training intervention (MTI) for improving cognitive function and exercise tolerance in geriatric patients.MethodsThirty-four patients (64–92 years) participated in this randomized controlled trial. Before and after the 5- to 7-week intervention period (MTI + IHHT vs. MTI + ambient air), cognitive function was assessed by the Dementia-Detection Test (DemTect) and the Sunderland Clock-Drawing Test (CDT), and functional exercise capacity by the total distance of the 6-Minute Walk Test (6MWT).ResultsDemTect and CDT indicated significantly larger improvements after MTI + IHHT (+16.7% vs. −0.39%, P < .001) and (+10.7% vs. −8%, P = .031) which was also true for the 6MWT (+24.1% vs. +10.8%, P = .021).DiscussionIHHT turned out to be easily applicable to and well tolerated by geriatric patients up to 92 years. IHHT contributed significantly to improvements in cognitive function and functional exercise capacity in geriatric patients performing MTI.
Hospital transfers from nursing homes (NHs) are frequent, burdensome for residents, and often avoidable. The evidence regarding the effectiveness of interventions to reduce avoidable transfers is limited, and most projects focus on nurses’ knowledge and skills. In the present project, interventions focusing on nurses and physicians are integrated, elaborated, and implemented in 17 NHs. Results of the 6 months preintervention period are reported. Hospital transfer rates (N = 1,520) and basic data on all residents (N = 1,238) were collected prospectively. Nurses’ preintervention knowledge and self-efficacy were assessed using standardized questionnaires (N = 330). Many hospital transfers were initiated by nurses without physician involvement, polypharmacy was common, and a high potential for reducing transfers by increasing physician presence was observed. Nurses showed rather low knowledge but high self-efficacy. The results are discussed against the background of the interventions including enhancement of physician presence and geriatric quality circles.
Background
Additional benefits of passive exposures to intermittent hypoxia and hyperoxia on cognitive performance and functional exercise capacity have been demonstrated in geriatric patients who performed a multimodal training program. The main goal of the present study was to evaluate effects of adding intermittent hypoxic-hyperoxic training (IHHT) to a multimodal training intervention (MTI) on mobility and perceived health in old individuals at a Geriatric Day Hospital.
Methods
Thirty-four patients between 64 and 92 years participated in the double blind, randomized and controlled clinical trial. The elderly patients attended in a 5–7 weeks lasting MTI (strength, endurance, balance, reaction, flexibility, coordination, and cognitive exercises) and performed IHHT (breathing 10–14% oxygen for 4–7 min followed by 2–4 min 30–40% oxygen) in the Hypoxic Group (HG) or placebo treatment with ambient air in the Normoxic Group (NG) in parallel. Before and after all treatments, mobility was assessed by the Tinetti Mobility Test (TMT), the Timed-Up-and-Go Test (TUG) and Barthel-Index, while perceived health was assessed by one part of the EQ-5D Test, the EQ visual analogue scale (EQ VAS).
Results
After the MTI plus IHHT or normoxia sessions, results of the TMT, TUG, Barthel Index and EQ-VAS revealed no significant difference between HG and NG (+ 14.9% vs + 15.4%,

p
= 0.51; + 4.2% vs + 3.6%,
p
= 0.56; + 37.9% vs + 33.9%,

Conclusions
IHHT added to MTI did not elicit additional improvements in perceived health and mobility compared to MTI alone.
