Prescribing thiamine to inpatients with alcohol use disorders: how well are we doing?

OBJECTIVES: Thiamine deficiency is a potentially dangerous sequela of alcohol use disorders (AUDs). European and British guidelines recommend administering high-dose parenteral thiamine 3 times daily to avoid consequences of thiamine deficiency such as Wernicke-Korsakoff syndrome (WKS), and suggest that traditional thiamine dosages are likely inadequate. Research into thiamine and WKS has lagged in the United States, and to date, no study has examined how thiamine is prescribed to inpatients with AUD in an American hospital. METHODS: Thiamine prescribing data (amount, route, and frequency schedule) were collected for inpatients at a large, American, teaching hospital, who were referred to the addiction psychiatry service for AUD. Data were analyzed using Statistical Product and Service Solutions. RESULTS: A total of 217 inpatients with AUD were included. A substantial percentage of them were not prescribed thiamine. Of those who were prescribed thiamine, nearly all were prescribed oral thiamine at traditional dosages, including high-risk patients. CONCLUSIONS: This is the first study to report on the prescribing of thiamine to inpatients with AUD at an American teaching hospital. It serves to confirm what many already suspected: that more education is needed to improve the diagnostic challenges of WKS, the detection of risk factors for WKS, and the adequate dosing of thiamine for prevention and treatment of WKS.

Cannabinoid hyperemesis syndrome: a case series and review of previous reports.

BACKGROUND: Cannabis is the most commonly used illicit substance worldwide. Cannabinoids or cannabinoid receptor agonists are often used to treat nausea, vomiting, and anorexia. However, in recent years, several medical journals have published reports of patients with nausea and vomiting thought to be induced by chronic cannabis use. OBJECTIVE: The authors seek to inform readers about Cannabinoid Hyperemesis Syndrome (CHS). METHOD: The authors describe four patients with chronic cannabis abuse, episodic, intractable nausea and vomiting, and compulsive hot water bathing. Previous cases of CHS are reviewed, pathophysiology is hypothesized, and difficulties with making the diagnosis are discussed. CONCLUSION: CHS should be strongly considered in the differential diagnosis of patients with intractable vomiting and/or compulsive hot water bathing.

Primitive reflexes associated with delirium: a prospective trial.

BACKGROUND: The presence of primitive reflexes (PRs) may have diagnostic or prognostic value in the evaluation of cognitive impairment. OBJECTIVE: We hypothesized that the presence of preoperative PRs would predict the development of postoperative delirium and that the emergence of PRs postoperatively would be positively associated with the emergence of delirium. METHODS: Patients participating in a larger study on the prophylaxis of postoperative delirium were evaluated for the presence of six PRs (grasp reflex [left and right], palmomental reflex [left and right], glabellar tap, and snout reflex), preoperatively and postoperatively. The presence of PRs was then correlated with the development of delirium. RESULTS: Of the 79 patients studied, 29% (n = 23) developed delirium during the postoperative period. The preoperative presence of one PR did not predict the development of delirium, but the only patient with >1 PR preoperatively went on to develop delirium in the postoperative period. Similarly, having one frontal release sign in the postoperative period did not correlate with delirium, while the appearance of more than one PR was associated with a greater likelihood of delirium. Of the 11 patients who had two or more frontal release signs during one postoperative examination, six (55%) developed delirium. Of the five patients who showed three or more frontal release signs, 4 (80%) developed delirium. CONCLUSION: Our study is the first to investigate the relationship between the appearance of PRs and the development of delirium. We have provided some evidence that PRs are associated with acute CNS dysfunction.

Development of a substance abuse consultation and referral service in an academic medical center: challenges, achievements and dissemination.

Approximately 25% of US hospital beds are occupied by individuals with active substance use disorders (SUD). Acute medical hospitalization provides an opportunity to address SUDs and provide patient-centered intervention and referral for treatment. Nationally, some hospitals have developed substance abuse consultation departments to improve the care of hospitalized substance users. In this paper we describe the Addiction Psychiatry Service (APS) in a large urban hospital which provides bed-side SUD consultation, screening, intervention and referral to treatment. APS utilizes the multiple disciplines of psychology, social work and medicine to integrate substance abuse services throughout the hospital and educate future generations of medical and psychology trainees. We conclude with how the APS service is informing the development of similar programs in other academic departments within our hospital and best practice recommendations to further disseminate this service model.
