Experience-Based Co-Design: A Method For Patient And Family Engagement In System-Level Quality Improvement, Bianca Fucile, Erica Bridge, Charlene Duliban, Madelyn P. Law Dr.

Patient Experience Journal

Integrating patient and family member needs, wants and preferences in healthcare is of utmost importance. However, a standardized patient and family engagement model to understand these needs, wants and preferences in order to translate into high quality improvement activities is lacking. Experience based co-design (EBCD) is an approach that enables patients, family members and healthcare providers to co-design improvement initiatives together. In this study, EBCD was employed to: 1) assess the current state of information and educational resources at a local oncology center and 2) partner with patients, family members, and healthcare providers to create quality improvement initiatives targeting identified …

The Paradigm Of Patient Must Evolve: Why A False Sense Of Limited Capacity Can Subvert All Attempts At Patient Involvement, Dave Debronkart Jul 2017

The Paradigm Of Patient Must Evolve: Why A False Sense Of Limited Capacity Can Subvert All Attempts At Patient Involvement, Dave Debronkart

Patient Experience Journal

This essay reviews the role of paradigms in molding the thoughts of a scientific field and looks rigorously at what two key terms mean – empowered and engaged – and how their interaction points to a new way forward, requiring a re-examination of our “paradigm of patient.” Five years ago, the Institute of Medicine’s Best Care at Lower Cost declared that patient-clinician partnerships are a cornerstone of a learning health system, a declaration that’s foundational to the era of involvement. How can we engineer that era correctly if our conception of “patient” is out of date? And how can we …


Pushing The Boundaries Of Patient Experience, Jason A. Wolf Phd Jul 2017

Pushing The Boundaries Of Patient Experience, Jason A. Wolf Phd

Patient Experience Journal

This special issue is designed to push the boundaries of patient experience a little farther. Beyond just examples of applying the critical principles of patient and family centered care or even practices of patient engagement, we have been pushed to move further down the perspective of partnership, to the era of “doing with” in which healthcare now finds itself. The idea of involvement as the descriptor selected to frame this issue, was due to its broad and representative nature. It reflects all the words on involving patients mentioned above, but gets further along to participation and ownership (or activation as …

After Closure: Options For Pursuing A High Performance Rural Health System, Andrew F. Coburn Phd

Rural Hospitals (Flex Program)

Presented at the 2017 National Rural Health Association Annual Meeting. Coburn, a member of the Rural Policy Research Institute Panel, discussed the following key questions: What kind of rural health system is possible in places that cannot support a full-service hospital? How does a rural community navigate the transition from hospital-centric care toward new models that deliver high performance? What implementation support will be needed? Coburn noted that there is no single model for re-configuring the rural health system after hospital closure; local assets, affiliations and partnerships, financial and delivery flexibility and capacities must be critically assessed to determine the …

Long-Term Sustainment Of Rapid Improvement Events: A Case Study In “Room Readiness”, Gabriela V. Coronel

Undergraduate Honors Theses

Shifting payment models from fee for service (FFS) to pay for performance (P4P) have fundamentally changed the environment of healthcare administration in the United States (Center for Medicaid and Medicare Services (CMS), 2011). Due to this shift, there has been an increase in demand for tracking and improving quality measures to ensure not only patient safety, but optimization of utilization. Constraints on resources and capacity, coupled with increasing safety measures has developed a new study of patient flow (Miró, Sánchez, Espinosa, et al., 2003). Decreasing patient room turnover times has the potential to maximize utilization while ensuring patient safety and …

Learning And Leading In The Experience Age, Jane Cummings Apr 2017

Learning And Leading In The Experience Age, Jane Cummings

Patient Experience Journal

A focus on experiences of care helps health systems realize the very transformations they look to achieve. This is because patient experience allows patients, families and carers to define value, enabling healthcare organizations to focus on what matters to them and not simply what is the matter with them. This is what we mean by an ‘experience age’, one in which clear connections are made between the things patients value and the clinical outcomes we look to achieve: where links are drawn between experience, clinical effectiveness, safety and cost in order to provide the very best care for all patients. …

Cyclosporine Exacerbates Ketamine Toxicity In Zebrafish: Mechanistic Studies On Drug–Drug Interaction, Bonnie L. Robinson, Melanie Dumas, Syed F. Ali, Merle G. Paule, Qiang Gu, Jyotshna Kanungo

United States Food and Drug Administration: Publications

Cyclosporine A (CsA) is an immunosuppressive drug commonly used in organ transplant patients to prevent allograft rejections. Ketamine is a pediatric anesthetic that noncompetitively inhibits the calcium-permeable N-methyl-D-aspartic acid receptors. Adverse drug–drug interaction effects between ketamine and CsA have been reported in mammals and humans. However, the mechanism of such drug–drug interaction is unclear. We have previously reported adverse effects of combination drugs, such as verapamil/ketamine and shown the mechanism through intervention by other drugs in zebrafish embryos. Here, we show that ketamine and CsA in combination produce developmental toxicity even leading to lethality in zebrafish larvae …

Detection Of Allergen Markers In Food: Analytical Methods, Girdhari M. Sharma, Sefat E. Khuda, Christine H. Parker, Anne C. Eischeid, Marion Pereira

United States Food and Drug Administration: Publications

Food allergens are proteins that are well tolerated by most, but can cause severe reactions in sensitive individuals. Since there is no cure for food allergy, strict adherence to an allergen-free diet is the only safe choice currently available for allergic consumers. Accurate food labeling can help consumers avoid foods containing an allergenic ingredient. Regulatory agencies have mandated the labeling of major food allergens on packaged foods to help with safe food choices. However, the inadvertent presence of an allergen in food due to cross-contact and labeling error can jeopardize consumer health. Analytical methods are developed for allergen detection and …
