Background:
Sedative-hypnotics, including benzodiazepines (BZDs) and benzodiazepine receptor agonists (BZD-RA), are considered potentially inappropriate medications (PIMs) in older adults. Academic detailing, an educational outreach delivered by trained clinicians to other clinicians to encourage evidence-based care, can promote deprescribing of PIMs.
Objective:
To evaluate the impact of academic detailing on sedative-hypnotic prescribing to older veterans.
Methods:
A retrospective analysis was performed to evaluate the impact of academic detailing on BZD and BZD-RA prescribing to veterans aged 75 years and older. Prescribing trends for primary care and mental health prescribers in the Veterans Health Administration (VA) Southeast Network were calculated for the 18 months before and after an initial academic detailing session for each prescriber. Pre-post interrupted time series analyses (ITSAs) were conducted, and period prevalence was calculated as the number of prescriptions per 1000 older veterans.
Results:
A total of 155 prescribers were followed for 36 months. BZD prevalence declined by 23% (69.08-53.33 per 1000 population; P < .001) and by 15% for BZD-RA (18.07-15.38 per 1000 population; P < .001). New starts on BZD declined by 54% (2.36-1.09 per 1000 population; P < .001) and new starts on BZD-RA declined by 53% (1.02-0.48 per 1000 population; P < .001). Alternative medications for insomnia increased by 23% (39.98-49.27 per 1000 population; P < .001). Findings from the ITSA confirmed those of the pre-post analysis with sustained effects in the postintervention period.
Conclusions:
Academic detailing was associated with reduced sedative-hypnotic prescribing in the primary care and mental health setting.

01:23Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

01:19Sedatives and Hypnotics Drugs: Benzodiazepines
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...
01:17Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
