Basic Geriatrics Knowledge Among Internal Medicine Trainees in a Teaching Hospital in Saudi Arabia.

To assess the basic knowledge of medical trainees, in the absence of a structured geriatrics curriculum, around a variety of geriatric medicine components that are considered essential for the care of the rapidly increasing elderly population. Eighty-three trainees at different levels of training in internal medicine were asked about a variety of common geriatric conditions. Those included: delirium, falls, geriatric syndromes, pain, cognitive impairment, and medications. The trainees' knowledge about common geriatric condition was overall poor. The most pronounced deficits included: the lack of familiarity in diagnosing geriatric syndromes (63 %) or managing them (67 %), the underestimation of the prevalence of delirium (49 %), and the tendency to undertreat pain (64 %). Poor familiarity with polypharmacy and its impact, as well as inappropriate prescription practices in the elderly were also observed. In the absence of a structured geriatric medicine curriculum, internal medicine trainees' knowledge about important geriatric conditions is poor, even if their internal medicine knowledge is overall adequate. This would translate into suboptimal care for this vulnerable and rapidly expanding segment of the population.

Falls in the elderly: spectrum and prevention.

OBJECTIVE: To provide family physicians with a practical, evidence-based approach to fall prevention in the elderly. SOURCES OF INFORMATION: MEDLINE was searched using terms relevant to falls among the elderly in the community and in institutions. Relevant English-language papers published from 1980 to July 2010 were reviewed. Relevant geriatric society guidelines were reviewed as well. MAIN MESSAGE: Falls are a common and serious health problem with devastating consequences. Several risk factors have been identified in the literature. Falls can be prevented through several evidence-based interventions, which can be either single or multicomponent interventions. Identifying at-risk patients is the most important part of management, as applying preventive measures in this vulnerable population can have a profound effect on public health. CONCLUSION: Family physicians have a pivotal role in screening older patients for risk of falls, and applying preventive strategies for patients at risk.

Melatonin decreases delirium in elderly patients: a randomized, placebo-controlled trial.

BACKGROUND: Disturbance in the metabolism of tryptophan and tryptophan-derived compounds (e.g., melatonin) may have a role in the pathogenesis of delirium. OBJECTIVE: To evaluate the efficacy of low dose exogenous melatonin in decreasing delirium. DESIGN: A randomized, double-blinded, placebo-controlled study. SETTING: An Internal Medicine service in a tertiary care centre in London, Ontario, Canada. PARTICIPANTS: 145 individuals aged 65 years or over admitted through the emergency department to a medical unit in a tertiary care hospital. INTERVENTION: Patients were randomized to receive either 0.5 mg of melatonin or placebo every night for 14 days or until discharge. MEASUREMENTS: The primary outcome was the occurrence of delirium as determined by Confusion Assessment Method (CAM) criteria. RESULTS: Of a total of 145 individuals (mean age (standard deviation): 84.5 (6.1) years) 72 were randomly assigned to the melatonin group and 73 to the placebo group. Melatonin was associated with a lower risk of delirium (12.0% vs. 31.0%, p = 0.014), with an odds ratio (OR), adjusted for dementia and co-morbidities of 0.19 (95% confidence intervals (CI): 0.06-0.62). Results were not different when patients with prevalent delirium were excluded. LIMITATION: An intention to treat analysis was not possible due to loss to follow-up. CONCLUSION: Exogenous low dose melatonin administered nightly to elderly patients admitted to acute care may represent a potential protective agent against delirium.
