Association Between Medical Marijuana Cardholder Status and Antiemetic Overuse.

The conscientious prescribing of antiemetics by chemotherapy-induced nausea and vomiting (CINV) risk was highlighted in the American Society of Clinical Oncology (ASCO) "Choosing Wisely" recommendations. The pharmacologic properties of medical marijuana (MMJ) may allow for decreased incidence of CINV; however, little is known about the effects of MMJ on the use of antiemetics. This study aimed to determine if MMJ cardholder status, which enables access to MMJ, is associated with antiemetic overuse among patients with cancer.

Clinical Impact of ASCO Choosing Wisely Guidelines on Staging Imaging for Early-Stage Breast Cancers: A Time Series Analysis Using SEER-Medicare Data.

Purpose: American Society for Clinical Oncology released the Choosing Wisely list in 2012, highlighting low-value procedures that lack evidence, advising against the use of positron emission tomography, computerized tomography, and radionuclide bone scans for the staging of early-stage breast cancer at low risk for metastasis. The objective of the study was to assess the impact of the American Society of Clinical Oncology Choosing Wisely guidelines on inappropriate staging imaging among early-stage breast cancers.

Methods: The Surveillance, Epidemiology, and End Results Program-Medicare data set was used to identify 50,004 women age 66 years and older with new incident diagnosis of early-stage breast cancer (stage 0 through stage 2a; T < 4, N = 0, and M = 0).

Exploring the Use of State Medical Cannabis Legislation as a Proxy for Medical Cannabis Use Among Patients Receiving Chemotherapy.

The use of medical cannabis is expanding in the USA. Due to conflicting, low-quality evidence, many oncologists may not feel confident to recommend it to patients. Given the potential for legal and financial risks when conducting clinical trials with medical cannabis, the use of observational data should be explored.

Nonprescription Medication Use in Hospice Patients.

Objective: Patients admitted to hospice are more vulnerable to age-related physiologic changes, polypharmacy, and inappropriate medication use and monitoring. The objective of this study was to characterize the utilization of nonprescription medications in a hospice population.

Methods: This was a retrospective study designed to characterize nonprescription or over-the-counter medication use in hospice patients.
