Objective: This study aimed to describe real-world experiences following a non-medical switch among adults with type 2 diabetes mellitus (T2DM) in the United States.

Methods: For this cross-sectional study, patients with T2DM (N?=?451) provided data on demographics, and how a non-medical switch of their anti-hyperglycemic agent (AHA) affected their general health, HbA1c levels and medication management, via an Internet-based survey. Patients self-reported their level of satisfaction with the original medication and emotional reactions to the non-medical switch. Patients who recently experienced a non-medical switch of their AHA(s) (n?=?379) were asked about the consequences of switching and their satisfaction with the switch (vs. the original) medication.

Results: Patients most frequently reported feeling very/extremely frustrated, surprised, upset and angry in reaction to a non-medical switch. Patients were somewhat satisfied with their original medication. Between 20% and 30% of patients reported the non-medical switch had a moderate/major effect on their general health, diabetes, mental well-being and control over their health. The blood glucose levels of recent switchers were somewhat/much worse (20.7%) and medication management was somewhat/much worse (12.9%) on the switch (vs. the original) medication. Some recent switchers reported old symptoms returning (7.7%) and experiencing new side-effects (14.2%).

Conclusions: Approximately one in five patients reported a moderate/major negative impact on their blood glucose level, diabetes, mental well-being, general health and control over their health following a non-medical switch. Findings suggest that a non-medical switch may have unintended negative health consequences and results in considerable burden across multiple domains for a sizeable minority of patients with T2DM.  相似文献

Breast cancer is an increasingly urgent problem in low- and mid-level resource countries of the world. Despite knowing the optimal management strategy based on guidelines developed in wealthy countries, clinicians are forced to provide less-than-optimal care to patients when diagnostic and/or treatment resources are lacking. For this reason, it is important to identify which resources commonly applied in resource-abundant countries most effectively fill the healthcare needs in limited-resource regions, where patients commonly present with more advanced disease at diagnosis, and to provide guidance on how new resource allocations should be made in order to maximize improvement in outcome. Established in 2002, the Breast Health Global Initiative (BHGI) created an international health alliance to develop evidence-based guidelines for countries with limited resources (low- and middle-income countries) to improve breast health outcomes. The BHGI serves as a program for international guideline development and as a hub for linkage among clinicians, governmental health agencies and advocacy groups to translate guidelines into policy and practice. The BHGI collaborated with 12 national and international health organizations, cancer societies and nongovernmental organizations to host two BHGI international summits. The evidence-based BHGI Guidelines, developed at the 2002 Global Summit, were published in 2003 as a theoretical treatize on international breast healthcare. These guidelines were then updated and expanded at the 2005 Global Summit into a fully comprehensive and flexible framework to permit incremental improvements in healthcare delivery, based upon outcomes, cost, cost–effectiveness and use of healthcare services.  相似文献
