Objective:
Electroconvulsive therapy (ECT) is a treatment of choice for severe depression but has been underutilized among black patients. This study investigates racial disparities in the administration of ECT in the state of Texas between 1998 and 2013 using population data.
Design:
Data from the Texas Department of State Health Services were obtained corresponding to the use for all ECT conducted in nonfederal settings during the period from January 2, 1998, to August 30, 2013. The data set comprised quarterly reports generated for each patient, totaling 27,931 patient quarters. Using year-by-year intercensal population estimates for the state of Texas, ECT treatments per capita were compared among black, white, Latina/Latino, and other individuals during this time period.
Results:
Significantly more white patients were treated each quarter than minority patients (P < 0.001), with Latina/Latino patients recording fewer treatment quarters than any other racial group (P < 0.005). Large discrepancies in diagnosis by race were observed. Black patients were less likely than white and Latina/Latino patients to be diagnosed with depression and 4 times as likely as white patients to carry a diagnosis of schizophrenia.
Conclusions:
Concordant with previous data, large racial disparities in the administration of ECT were found in this Texas data set. Despite the limited nature of this data set, these results suggest that continued investigation is required to determine factors responsible for these disparities.

Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
Routes of Drug Administration: Enteral
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...
Routes of Drug Administration: Parenteral
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...
Routes of Drug Administration: Overview
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...

Drug Administration and Therapy Phases: Overview
The pharmaceutical phase focuses on leveraging the physicochemical properties of the drug to design and manufacture an effective product. Variants include orally administered tablets or capsules, topical creams or ointments, and parenteral-delivery solutions or emulsions.
