Department of Bioethics and Decision Sciences

The Department of Bioethics and Decision Sciences is part of the Geisinger College of Health Sciences, the research and education arm of Geisinger. It is also deeply embedded in the 30,000-employee integrated health system, whose 10 hospital campuses and 100+ clinics serve 6.7 million Pennsylvanians and 500,000 health plan members. The department serves multiple functions spanning research, education, clinical and research ethics consultation, policy development, patient safety and quality improvement.

Much of this work involves helping people — patients, caregivers, research participants, researchers and organizational leaders — make better decisions by defining options, identifying stakeholder preferences and values, and weighing trade-offs. 

The department’s innovation is bringing together faculty and staff from a wide range of disciplines and fields comprising bioethics (which focuses on defining and analyzing what decisions people should make) and the decision sciences (which focus on the scientific study of how people actually make decisions), including law, philosophy, religious studies, bioethics, cognitive science, social psychology, behavioral economics, medicine, nursing, clinical social work and public health. 

Working independently and collaboratively with internal and external colleagues, the department has two intertwined objectives:

to better understand how people make decisions related to healthcare, science and innovation; and 

to help people make “better” decisions — those that are more ethical, more aligned with evidence and with their own considered judgments or their patients’ preferences, less influenced by biases of various kinds, and that serve the Geisinger mission of making better health easier.

Learn more about the department’s functions below.


Although department researchers also pursue more traditional research in their respective fields of bioethics and decision sciences, the department uniquely brings them together to collaboratively investigate questions at their intersection, especially in the domains of health, science and innovation. 

Researchers in the department use a wide range of quantitative and qualitative methods, and enjoy access to over 25 years of electronic health record and claims data, and over 300,000 consented participants in the MyCode Community Health Initiative biobank. 

They investigate questions such as:

  • When and why do people exhibit aversion to, or appreciation of, the use of “algorithms” and other AI tools in decision-making?
  • How do people incorporate beliefs, misbeliefs, and concerns about data privacy into their decisions about healthcare and research?
  • How do people (mis)understand genetic information, and how is this information best presented?
  • Does the disclosure to adolescents of genetic variants associated with adult-onset disease place them at risk of psychological harm?
  • When and why do people prefer to implement untested practices and policies instead of subjecting them to A/B testing, and how can we intervene to reduce this bias to advance a learning health system? 
  • How does moral distress affect the quality of clinical decisions? How does moral distress affect the functioning of healthcare teams?
  • Do clinicians neglect important information when interpreting diagnostic test results, and if so, how can the incidence of such biases be reduced?
  • Are laypeople and clinicians rational when making decisions about rationing healthcare?
  • When and why are some people hesitant to be vaccinated and how can that be addressed?
  • What kinds of “nudges” are acceptable to stakeholders, when and why?

Examples of our work (bold indicates Geisinger author):


The department is part of the Geisinger College of Health Sciences, which includes (in addition to its Research Institute) the Geisinger Commonwealth School of Medicine, the Geisinger School of Nursing and the Geisinger School of Graduate Education (which includes master’s programs in Biomedical Sciences and Genetic Counseling and graduate certificates in Pharmacy Systems Science and Healthcare Leadership). 

Department faculty are members of Geisinger’s Academy of Educators and participate in graduate and continuing education in (primarily clinical) ethics and the decision sciences. This includes producing an annual spring bioethics symposium for medical residents and fellows and developing and delivering program-specific educational content in several of Geisinger’s numerous medical and nurse fellowship and residency programs

The department also develops ethics quality advisories (EQAs) — brief, targeted, widely-distributed communiques about such special topics as advance directives, surrogate decision makers and healthcare decision making with intellectually disabled patients. In addition, the department develops strategic educational initiatives on these and other topics for delivery to clinicians.  

Finally, researchers in the department contribute to education by mentoring junior faculty, postdoctoral fellows, predoctoral fellows, and undergraduate and medical student interns interested in research, by guest lecturing in undergraduate and graduate classes across the country, and by serving as faculty at continuing professional education conferences.

Ethics consultation

Members of the department staff two advice and consultation services in clinical and research ethics, respectively, and oversee a network of hospital ethics committees.

Clinical Ethics Advice and Consultation Service (CEACS): The CEACS is staffed by department members who are certified healthcare ethics consultants. It is available 24 hours a day, seven days a week, free of charge, to any Geisinger patient, patient family member or loved one, or healthcare team member at all system locations in both in- and out-patient settings. 

Ethics consultants help navigate the ethical challenges of uncertainty and conflict inherent in clinical decision-making and care. Employees with access to TigerConnect may request a consult by contacting the ethicist on call, who will respond as soon as possible. Patients, their family members or friends, or surrogate decision makers (along with staff without access to TigerConnect) may request a consult by calling 570-214-2400.

Research Ethics Advice and Consultation Service (REACS): The REACS is staffed by department members with expertise in the responsible conduct of research. It is available, free of charge, to investigators and other research team members as well as to IRB members and staff. REACS provides members of the research community with timely consultation on ethical issues in the design and conduct of research (including but not limited to research involving human participants), quality improvement, and innovation.

Hospital ethics committees: Members of the department participate in and oversee Geisinger’s five hospital ethics committees. Each committee is engaged in policy development, review, and revision; quality oversight of clinical ethics advice and consultation; and clinical ethics education.


Members of the department are responsible for the development, review and (as appropriate) revision of several system policies and guidelines, and they participate in the development and revision of many more. These policies and guidelines span the range of bioethics subfields (e.g., clinical ethics, research ethics, public health ethics, the ethical, legal and social implications (ELSI) of emerging technologies) and include the following topics: 

  • Surrogate decision-making
  • Assessing decisional capacity
  • Shared decision-making
  • Advanced care planning/advance directives
  • Unrepresented patients
  • Crisis standards of care 
  • Allocation of scarce resources 
  • Employee vaccine mandate exemptions
  • Trial prioritization
  • Appropriate use, disclosure and sharing of data 
  • Appropriate use of MyCode Community Health Initiative data and engagement of participants
  • Appropriate use of health AI
  • Integrative medicine
  • Program evaluation
Safety and quality

Members of the department lead or participate in a range of initiatives aimed at improving the safety and quality of care for Geisinger’s patients – and of the environment for both patients and employees. 

MyCareChoices: Department faculty serve on the steering committee for this broad-based initiative to improve the quality of decision making and care for patients grappling with serious advanced illness by (1) increasing the uptake of advance care planning and (2) enhancing the communication skills of clinicians for person-centered, shared decision making. Department faculty are also among the core faculty for Shared Decision Making in Serious Illness, the communication skills-focused component of MyCareChoices.

Patient safety: Department faculty serve on the steering committee for Communication and Optimal Response (CANDOR), the AHRQ-developed framework and process for improving organizational responses to adverse events and errors that Geisinger adopted in 2018. In collaboration with the Healthcare Communication Program, department faculty lead the education and training for senior clinicians and clinical leaders in the “ethical, effective disclosure of events and errors” workshop, a key programmatic element of CANDOR.

Patient/Surrogate misconduct: Department faculty co-lead this system-wide initiative to develop more effective responses to the challenges of misconduct on the part of patients and their loved ones or surrogates. Faculty were instrumental in developing the system’s patient and visitor misconduct policy, as well as guidelines to inform the behavior and responses of frontline clinicians who are confronted with misconduct. 

Organizational culture — professionalism, psychological safety and just culture: Department faculty collaborated with faculty from the Center for Professionalism and Well-Being to develop a toolkit of resources for improving aspects of the system’s organizational culture, including workshops on: giving and receiving effective feedback; resolving and transforming conflict; and fostering psychological safety. Faculty also collaborate with residency and fellowship program directors to develop and offer education and trainings designed to advance professionalism on the part of learners. Finally, bioethics faculty are integrally involved in the ongoing development of standards of professionalism for focused implementation in the learning environment.
