The hospital admissions study in England: Are there alternatives to emergency hospital admission?
Study objective - To assess the potential for substituting alternative forms of care for admission to an acute hospital in particular groups of patients. Design - A screening tool, the intensity-severity-discharge review system with adult criteria (ISD-A), developed for hospital utilisation review in the USA, was used in a cohort of hospital admissions to identify a group of patients who could potentially have been treated outside the acute hospital. These patients were further assessed by a panel of general practitioners (GPs) to determine the most appropriate alternative form of care. A cost analysis was performed on the results obtained. Setting - General medicine and geriatric specialties in one acute hospital in the south western region. Patients - Patients comprised a sample of 701 admitted to general medical and geriatric specialties. Main results - The screening tool identified 19.7% of admissions for whom there was potential for treatment outside the acute hospital. Assessment by the GP panel reduced this potential to between 9.8% and 15.0% of emergency admissions. The alternatives most frequently identified as 'most appropriate' were the community hospital-GP bed and the urgent outpatient assessment (within either 24 or 48 hours). Potential resource savings based on the average cost were relatively small. This potential seemed to be greater for the alternative of the urgent outpatient assessment. Conclusions - Potential exists for treating a proportion of patients in lower intensity alternatives to the acute hospital. If this potential were exploited few resource savings would occur

Zebrafish disease models in drug discovery: from preclinical modelling to clinical trials
Numerous drug treatments that have recently entered the clinic or clinical trials have their genesis in zebrafish. Zebrafish are well established for their contribution to developmental biology and have now emerged as a powerful preclinical model for human disease, as their disease characteristics, aetiology and progression, and molecular mechanisms are clinically relevant and highly conserved. Zebrafish respond to small molecules and drug treatments at physiologically relevant dose ranges and, when combined with cell-specific or tissue-specific reporters and gene editing technologies, drug activity can be studied at single-cell resolution within the complexity of a whole animal, across tissues and over an extended timescale. These features enable high-throughput and high-content phenotypic drug screening, repurposing of available drugs for personalized and compassionate use, and even the development of new drug classes. Often, drugs and drug leads explored in zebrafish have an inter-organ mechanism of action and would otherwise not be identified through targeted screening approaches. Here, we discuss how zebrafish is an important model for drug discovery, the process of how these discoveries emerge and future opportunities for maximizing zebrafish potential in medical discoveries
