Reduced Clostridioides difficile infections in hospitalised older people through multiple quality improvement strategies.

OBJECTIVES: To reduce infections with Clostridioides difficile (CDI) in geriatric patients by interventions easily implementable in standard clinical care. METHODS: Prevalence and incidence of CDI between January 2015 and February 2020 were analysed (n = 25,311 patients). Pre-intervention status was assessed from April 2016 to March 2017 (n = 4,922). Between May 2017 and August 2019, a monocentric interventional crossover study (n = 4,655) was conducted including standard care and three interventions: (A) sporicidal cleaning of hospital wards, (B) probiotics and (C) improvement in personal hygiene for CDI patients. This was followed by a multicentric comparison of the interventional bundle (A + B + C) between September 2019 and February 2020 (n = 2,593) with the pre-intervention phase. In 98 CDI cases and matched controls individual risk factors for the development of CDI were compared. RESULTS: Time series analyses of CDI cases revealed a reduction in the prevalence of CDI in all three participating centres prior to the multicentric intervention phase. In the monocentric phase, no effect of individual interventions on CDI prevalence was identified. However, an aggregated analysis of CDI cases comparing the pre-intervention and the multicentric phase revealed a significant reduction in CDI prevalence. Risk factors for the development of CDI included use of antibiotics, anticoagulants, previous stay in long-term care facilities, prior hospital admissions, cardiac and renal failure, malnutrition and anaemia. CONCLUSIONS: The observed reduction in CDI may be attributed to heightened awareness of the study objectives and specific staff training. Individual interventions did not appear to reduce CDI prevalence. A further randomised trial would be necessary to confirm whether the bundle of interventions is truly effective.

[Geriatrics - an interdisciplinary challenge]. / Geriatrie - eine interdisziplinäre Herausforderung.

The care of elderly patients will continue to challenge the healthcare system over the next decades. As a rule geriatric patients suffer from multimorbidities with complex disease patterns, and the ability to cope with everyday life is severely reduced. Treatment is provided by a multiprofessional geriatric team, and the primary goal is improvement of functional status, quality of life in the social environment and autonomy by employing a holistic approach. In Germany geriatric care is provided by physicians from various medical specialties (e.g. general practitioners, internists, neurologists and psychiatrists). In the training for the subspecialty clinical geriatrics, these specialties enjoy equal rights. Recent efforts to establish a qualification as physician for internal medicine and geriatrics have initiated a discussion to make the suitability for qualification as a geriatrician dependent on the medical specialty. Geriatric patients benefit from multidisciplinary cooperation. Neurologists possess great expertise in the treatment of patients with dementia, depression, delirium, consequences of degenerative spinal cord diseases and vertebral bone fractures, stroke, Parkinson's syndrome, epileptic seizures, vertigo and dizziness, neuropathies, lesions of peripheral nerves and in the multimodal therapy of pain. To function in a position of responsibility in a geriatric department, neurologists need skills in general internal medicine. These are acquired either on a geriatric ward or during specialization as a neurologist by full time secondment to large neurological or interdisciplinary intensive care units.
