MedicalResearch.com: What is the background for this study?
Dr. Allan: A large volume of observational (lower-level) research links lower Vitamin D levels with a long list of health concerns. Other non-clinical studies show the biochemical and physiological actions of Vitamin D could impact many health states. These factors have led many clinicians and scientists to advocate strongly for Vitamin D supplementation. However, this type of research can draw false connections. Therefore, we must examine high-quality randomized studies to determine if Vitamin D supplement can help people live longer, have improved health or avoid negative health outcomes.

Laura Ferris, M.D., Ph.D.
Associate professor, Department of Dermatology
University of Pittsburgh School of Medicine and
Member of the Melanoma Program
University of Pittsburgh Cancer Institute
MedicalResearch.com: What is the background for this study?
Dr. Ferris: Rates of melanoma, the most dangerous form of skin cancer, are on the rise, and skin cancer screenings are one of the most important steps for early detection and treatment. Typically, patients receive skin checks by setting up an appointment with a dermatologist. UPMC instituted a new screening initiative, which was modeled after a promising German program, the goal being to improve the detection of melanomas by making it easier for patients to get screened during routine office visits with their primary care physicians (PCPs). PCPs completed training on how to recognize melanomas and were asked to offer annual screening during office visits to all patients aged 35 and older. In 2014, during the first year of the program, 15 percent of the 333,788 eligible UPMC patients were screened in this fashion.

Sapna Kaul, Ph.D
Huntsman Cancer Institute

Salt Lake City, UT 84112
Medical Research: What is the background for this study? What are the main findings?
Dr. Kaul: The United States has the highest healthcare expenditures in the world, and close to one-third of these expenditures are believed to be unnecessary. One potential reason for these unnecessary expenditures is that patients may ask for medical services that are unnecessary. At the same time, primary care physicians (PCP) could find it difficult to refuse to prescribe unnecessary medical services as they may worry that it may compromise patient satisfaction. Also, there is a shortage of primary care workforce in the U.S. and PCPs may have insufficient time to effectively address patient requests.
We investigated 2 types of unnecessary medical practices initiated by patient requests:
(1) providing unnecessary specialty referrals, and
(2) prescribing brand-name drugs when generic alternatives were available.
To explore these practices, we used data on 840 U.S. PCPs from a national survey of physicians conducted in 2009. Over 50% of primary care physicians reported providing unnecessary specialty referrals and 39% prescribed brand-name drugs at patient requests. Several provider and organizational factors, such as physician specialty and solo/2-person practice, were related to reporting unnecessary practices.

Medical Research: What is the background for this study?
Dr. Mavandadi: Mental health (MH) conditions are underidentified and undertreated in later life. This is particularly true among subgroups of older adults who are more vulnerable to developing mental health issues, have poor access to specialty care, and are less responsive to treatment and therapy. Thus, we sought to evaluate longitudinal MH outcomes among low-income, community-dwelling older adults enrolled in an evidence-based, collaborative mental health care management service (i.e., the SUpporting Seniors Receiving Treatment And INtervention (SUSTAIN) program). The SUSTAIN program integrates mental health with primary care (which is where the majority of behavioral health conditions in later life are managed) and provides standardized, measurement-based, software-aided MH assessment and connection to community resources to older adults by telephone.
While there is a strong evidence base for the efficacy of collaborative care models for me conditions, little is known about the amount or level of patient and provider support that is needed to achieve optimal behavioral health outcomes. Thus, we specifically examined outcomes among older adults randomized to one of two program arms of varying intensity: MH symptom monitoring alone or
