Race, economic status, and disparities in the receipt of benzodiazepine prescriptions in a large primary care sample

OBJECTIVE

To evaluate the relationship between race, economic status, and patient characteristics with benzodiazepine prescribing in an urban and suburban primary care context.

METHOD

This retrospective study used data from a previously described cohort of patients seen in a large Ohio healthcare system's primary care clinics from 2019 to 2020. Associations and interactions between race, economic status (using median income of patient ZIP code as a proxy), patient characteristics, and prescription of benzodiazepines were assessed using multivariable logistic regression.

RESULTS

455,537 patients had 1,643,473 primary care visits, and 5.8% of patients were prescribed a benzodiazepine. White patients were prescribed benzodiazepines more often than Multiracial/Multicultural, African American and Asian American patients (6.5%, 3.8%, 2.7% and 2.0% respectively). Patients from lower income ZIP codes were less likely to receive a prescription. Interaction effects were observed between race, patient economic status, gender, insurance status, and diagnoses (general anxiety disorder, insomnia, and panic disorder). The largest prescribing disparities by race were among patients with these three diagnoses. The largest disparity in prescription by income was seen in African American patients.

CONCLUSION

African American, Multicultural/Multiracial and Asian American patients were less likely than White patients to receive benzodiazepine prescriptions. Middle and lower-income patients are particularly susceptible to this prescribing disparity.

Endogenous opiates and behavior: 2019

This paper is the forty-second consecutive installment of the annual anthological review of research concerning the endogenous opioid system, summarizing articles published during 2019 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides and receptors as well as effects of opioid/opiate agonists and antagonists. The review is subdivided into the following specific topics: molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors (1), the roles of these opioid peptides and receptors in pain and analgesia in animals (2) and humans (3), opioid-sensitive and opioid-insensitive effects of nonopioid analgesics (4), opioid peptide and receptor involvement in tolerance and dependence (5), stress and social status (6), learning and memory (7), eating and drinking (8), drug abuse and alcohol (9), sexual activity and hormones, pregnancy, development and endocrinology (10), mental illness and mood (11), seizures and neurologic disorders (12), electrical-related activity and neurophysiology (13), general activity and locomotion (14), gastrointestinal, renal and hepatic functions (15), cardiovascular responses (16), respiration and thermoregulation (17), and immunological responses (18).
