Physician Assistants and Information Needs for Clinical Decision-Making- Outline
• History of the profession• Value of the profession to medical practice• IOM Core Competencies and Evidence-based
practice• Rural practice challenges• Rochester and University of Wales Studies• Use of clinical information for patient care
decision-making- survey results for physician assistants
Physician Assistant- History of the Profession
• Nationwide shortage of physicians recognized in the 1960s
• Health Professions Assistance Act of 1963• Profession created to relieve shortage and

Rochester StudyConducted in the early ’90s. Joanne Marshall, PIMostly urban physicians and residents, and rural physicians served by circuit
librariansLibrarian-mediated searching, results evaluated for clinical usefulness in
decision-makingMarshall, J.G. (1992). The impact of the hospital library on clinical decision making: The Rochester study. Bull Med Libr Assoc, 80(2),169–78.
University of Wales AberystwythConducted in 2005. Spink, Thomas, Urquhart & WeightmanToolkit development, evaluation of impact of library services on patient careParticipants mostly did their own searching of the literaturePhysicians, allied health personnel, nurses, administratorshttp://cadair.aber.ac.uk/dspace/bitstream/2160/355/4/NKS_ImpactStudyReport_Nov07.pdf
Results of Rochester Study
• Response rate 46.4%- 208 useable surveys• 96.9% of physicians reported library-provided
information was of clinical value for patient care• 71.6% reported a change in the advice given to a patient• 59.6% reported a change in choice of other treatments• 50.3% reported a change in the choice of tests• 49.0% reported avoidance of additional tests and
procedures• 21.2% reported avoidance of surgery• 19.2% reported a reduction in length of stay
Results of University of Wales Study
• Response rate was 20.3%- 169 useable surveys• Respondents searched the literature themselves• Nearly half of all searches (46.2%) were related to direct patient
care • 54.4% stated that information would contribute to advice to
colleagues• 45% of respondents stated that the information would contribute to
advice given to the patient or caregiver• 37.9% stated a change to service delivery or practice• 23.7% stated that information improved quality of life for
patient/family• 12.4% stated that information would impact choice of diagnostic test

Current Study• 123 critical access hospitals (CAHs)- Washington,
Alaska, Montana, and Idaho• Definition of rural- CAHs- 25 beds or less• 100 CAH facilitators attempted to distribute surveys• 50 final participating CAHs- 852 total practitioners
661 Physicians

125 Physicians (M.D.) (60.1%)
22 Physicians (D.O.) (10.6%)

24 Nurse Practitioners (11.5%)
All respondents searched for information themselves
56.8% of PAs needed information for a patient
86.5% of PAs needed drug information
100% of PAs chose direct patient care as a reason for needing information
91.7% stated that the information impacted advice given to patient
Physician Assistants and Information Needs for Clinical Decision-MakingPreliminary Survey Outcomes- continued
• 59.5% stated that the information avoided patient misunderstanding of disease
• 69.4% stated that information avoided additional tests or procedures• 70.3% chose print books as their most used resource• 54.1% tie between UpToDate® and print journals, as a resource• 86.5% accessed the information from their offices• 35.1% accessed the information from a mobile device• 54.1% felt completely successful in their search for information• 48.6% took less than 10 minutes, 35.1% 10 to 30 minutes to search• 55.9% want more access to online journal databases• 52.9% want more access to e-books• 52.9% want more CME• 50% stated access to patient education materials would be helpful to their
practice
Physician Assistants and Information Needs for Clinical Decision-Making
Preliminary findings re: patient education suggest:
• Rural PAs want to be able to access EB information for patient care
• They desire to be lifelong learners• They want clinical information to be available online• They use and share new knowledge with their patients
and families• They are interested in having more resources for patient
education
