MedicalResearch.com Interview with:
Scott Stroup, MD, MPH
Professor of Psychiatry
Director, Program for Intervention Effectiveness Research,
Associate Director for Adult Services, Division of Mental Health Services and Policy Research, New York State Psychiatric Institute
Department of Psychiatry, College of Physicians and Surgeons, Columbia University, New York, New York
MedicalResearch: What are the main findings of the study?
Dr. Stroup: We conducted a study sponsored by the National Institute of Mental Health that compared long-acting injectable antipsychotics for people with schizophrenia. Long-acting injectable antipsychotics, also known as depot antipsychotics, are used to promote treatment adherence. We compared a newer injectable antipsychotic, paliperidone palmitate, to an older one, haloperidol decanoate. We did not find an advantage for the newer drug in overall effectiveness. The drugs performed very similarly, and were tolerated about the same.

MedicalResearch.com: What are the main findings of the study?
Dr. Tamblyn: Higher drug costs are associated with a higher probability of primary non-adherence, whereas better follow-up by the prescribing physician, and a policy to provide medication at no cost for the very poor increase the likelihood of adherence

MedicalResearch.com: What are the main findings of your study?
Dr. Osborn: We found that knowing how to take your diabetes medications (e.g., what to do if a dose is missed), believing medications are good for you, and having the appropriate skills to take them regardless of the situation (e.g., when life is busy, when in public) accounts for 41% of why people successfully take their diabetes medications, which, in turn, explains 9% of their glycemic control.

Dawn L. Hershman, MD MS

Herbert Irving Comprehensive Cancer Center
Columbia University Medical Center
MedicalResearch.com: What are the main findings of the study?
Dr. Hershman: We have found in the past that compliance to 5 years of hormone therapy for the adjuvant treatment of breast cancer is low. While toxicity is a main reason, other factors are also important. Recent studies suggest out of pocket costs are high among cancer patients. We evaluated the change in adherence to hormone therapy after the introduction of generic Aromatase inhibitors. We found that discontinuation decreased and adherence increased with generic aromatase inhibitors compared to brand name. we found that higher co-payments were associated with decreased adherence and increased discontinuation. We also found that patients in the highest income group were more likely to be adherent to hormone therapy.

Dr. Wanpen Vongpatanasin, MD
Professor of Medicine
Director, Hypertension Section, Cardiology Division
UT Southwestern Medical Center
MedicalResearch.com: What are the main findings of the study?
Dr. Vongpatanasin: We found that more than 50% of patients with resistant hypertension were non-adherent to at least one drug prescribed by their primary care physicians for blood pressure control.
When we provided this information back to the patients, as part of care in our hypertension specialty clinic, we found that many patients report difficulty taking prescribed medications due to either associated side effects or cost of the medication. When we adjusted patient's medications to fit their needs, BP levels were substantially improved during subsequent visits without increasing the number of medications.

Dr. Jinoos Yazdany MD, MPH
Assistant Professor in Residence
UCSF School of Medicine
MedicalResearch.com: What are the main findings of the study?
Answer: For almost all of the drugs we examined, we found that less than half of patients adhered to treatment. For some drugs, less than one-third of individuals were adherent. The average medication possession ratios were low across all drugs.
We found that several factors played an important part in adherence. Younger individuals were less likely to adhere to treatment for several drugs, and we also found racial/ethnic differences, with Black, Hispanic and Native populations having lower adherence. We also found geographic variation in adherence, with individuals in the Northeast being the most likely to adhere to treatment.
