Pharmacists and Naloxone: Barriers to Dispensing and Effectiveness of an Educational Outreach Program.

BACKGROUND: The Illinois Naloxone Standing Order allows community pharmacists to dispense naloxone; however, this policy initiative may be underutilized. OBJECTIVE: Our study aims to characterize naloxone dispensing barriers, overall and by pharmacy type, make recommendations that can inform future policies to improve naloxone access, and evaluate outreach initiative effectiveness from academic detailers' perspectives. METHODS: We conducted a retrospective analysis of semistructured data collected as part of an educational outreach program targeting Illinois community pharmacists in 2021. Academic detailers conducted educational outreach visits across community pharmacy settings (i.e., primary pharmacy, grocery pharmacy, or independent pharmacy) to promote standing order use and discuss barriers pharmacists face when dispensing naloxone. Following each visit, detailers recorded visit characteristics, pharmacist-identified obstacles impacting naloxone dispensing, and visit effectiveness. RESULTS: Detailers performed in-person visits at 270 (78%) of 348 targeted sites. A lower proportion of independent pharmacies (61%) routinely stock naloxone than primary (95%, P < 0.001) or grocery (98%, P < 0.001) pharmacies. Among pharmacists at independent pharmacies, 43% indicated they were highly or extremely comfortable dispensing naloxone, a significantly lower proportion than pharmacists at grocery (79%, P < 0.001) or primary (68%, P < 0.001) pharmacies. The prevalence of salient barriers to naloxone dispensing was: cost/insurance issues (primary pharmacy = 38% vs. grocery pharmacy = 36% vs. independent pharmacy = 28%, P = 0.46), stigma (36% vs. 49% vs. 16%, P < 0.05), and lack of standing order enrollment (0% vs. 0% vs. 49%, P < 0.05). On average, detailers perceived visits as less useful to pharmacists working at independent pharmacies than those at primary or grocery pharmacies. CONCLUSIONS: Over 80% of pharmacists reported facing greater than one naloxone dispensing barrier. While cost/insurance issues appear ubiquitous, patient stigma-related factors were prevalent in primary and grocery pharmacies. Although many pharmacists are comfortable dispensing naloxone under the standing order, pharmacists at independent pharmacies are less comfortable, potentially secondary to lower standing order enrollment.

The genotypic spectrum of ALDH7A1 mutations resulting in pyridoxine dependent epilepsy: A common epileptic encephalopathy.

Pyridoxine dependent epilepsy (PDE) is a treatable epileptic encephalopathy characterized by a positive response to pharmacologic doses of pyridoxine. Despite seizure control, at least 75% of individuals have intellectual disability and developmental delay. Current treatment paradigms have resulted in improved cognitive outcomes emphasizing the importance of an early diagnosis. As genetic testing is increasingly accepted as first tier testing for epileptic encephalopathies, we aimed to provide a comprehensive overview of ALDH7A1 mutations that cause PDE. The genotypes, ethnic origin and reported gender was collected from 185 subjects with a diagnosis of PDE. The population frequency for the variants in this report and the existing literature were reviewed in the Genome Aggregation Database (gnomAD). Novel variants identified in population databases were also evaluated through in silico prediction software and select variants were over-expressed in an E.coli-based expression system to measure α-aminoadipic semialdehyde dehydrogenase activity and production of α-aminoadipic acid. This study adds 47 novel variants to the literature resulting in a total of 165 reported pathogenic variants. Based on this report, in silico predictions, and general population data, we estimate an incidence of approximately 1:64,352 live births. This report provides a comprehensive overview of known ALDH7A1 mutations that cause PDE, and suggests that PDE may be more common than initially estimated. Due to the relative high frequency of the disease, the likelihood of under-diagnosis given the wide clinical spectrum and limited awareness among clinicians as well as the cognitive improvement noted with early treatment, newborn screening for PDE may be warranted.
