Methods in Health Services and Outcomes Research PHMS-702 Course Data Number: Title: Credit-hours: Department: School/College: Type: PHMS-702 Methods in Health Services and Outcomes Research 3 Health Management and Systems Sciences School of Public Health and Information Sciences Lecture Catalog Description An overview of quantitative research methods for evaluating population health, including evaluations of comparative efficacy of medical interventions, psychometrics for assessing questionnaires, and effectiveness of clinical preventive and practice guidelines. Course Description This course is about methods for measuring varieties of quality in healthcare: methods to assess the quality of published research, examining context and quality of standardized questionnaires for health-related quality of life (HRQL) assessments, and investigating effectiveness of programs / applications / policies to improve the quality of care, health status of populations, etc. We examine quality from multiple perspectives – individuals in the context of their daily social roles, for example, and examining quality perspectives through the lens of organizations with intentions to change the healthcare system, focusing on case studies of the Wagner’s chronic illness care model, models for pay-for-performance and other current topics. Hands-on computer applications in quantitative research methods are present during the last hour, including skills for hypothesis testing, mathematical modeling and interpretation of common statistical tests, using analytic softwares like SPSS and Excel on existing datasets. Course Objectives Upon completion of this course, the successful student is able to: Describe differences in approaches to health services research, including primary data collection, secondary analysis of existing datasets, and hypothesis-free data mining. Identify, describe, and discuss the content, strengths, and limitations of some commonly used questionnaires used to measure functional status, person-centered health status, and health-related quality of life Describe, interpret, and discuss basic psychometric properties of questionnaires for reliability, types of validity, and responsiveness of health-related quality of life assessments, including measures among those with impairments, disabilities, and handicaps Page 1 of 14 Methods in Health Services and Outcomes Research PHMS-702 Describe processes about how to conduct a systematic review, especially in relationship to processes for developing clinical preventive guidelines and clinical practice guidelines Discuss methods for mathematical modeling as the basis for statistical risk adjustments (including, for example, indicators for physiologic risk, socio-demographics, comorbidities, severity of disease, severity of illness, and case-mix) as potential confounders in health services research Discuss applications of health services research methods for quality improvement, benchmarking, performance profiling, public reporting, and pay for performance Apply basic skills for data analysis, presentation, editing, and interpretation of statistical data, using Excel and SPSS software.

Other Required Reading The required reading by class is available in Blackboard and is drawn from journal articles and other sources. A sample of the required reading list is in Attachment 1. Page 6 of 14 Methods in Health Services and Outcomes Research PHMS-702 Additional Suggested Reading The suggested reading by class is available in Blackboard and is drawn from journal articles and other sources. A sample of the suggested reading list is in Attachment 2. Prepared Materials Used by Instructors Materials used by instructors in class are available to students via Blackboard no later than 24 hours following the class. These may include outlines, citations, slide presentations, and other materials. There is no assurance that the materials include everything discussed in the class. Other Materials All students are required to have a PC with minimal specifications as per SPHIS policies (See https://louisville.edu/it/services/software/school-of-public-health-and-informationsciences.html/document_view ). Student should bring their laptops to class with SPSS ver. 17 loaded for use during the last hour, or applications section, of each class. Additional required softwares: SPSS ver. 17. A CD of SPSS ver. 17 may be purchased as a companion to Wagner’s text for a small extra charge. According to the publisher, the license for that version of SPSS is valid for four years. This is longer than the duration of license and access for SPSS versions purchased through UofL IT Express (due to more aggressive updating policies at UofL). Student may choose to purchase of SPSS using either of these or other options. Course Policies Attendance and Class Participation Attendance in class is highly encouraged. Unexcused absences will result in lower evaluation scores. The philosophy of education for this course is that learning is an interactive process that is engendered through participation in discussions and other participatory exercises. Concepts that support learning objectives are discussed and developed during class time, and supported again through other assigned learning activities, such as classroom presentations, statistical applications, reading assignments and homework. As such, active class participation is expected. Students are expected to arrange for excused absences before class by talking with the course director or co-directors, and by making an e-mail request before the absence, if possible. Communications after the fact are acceptable in some situations, including for example acute illnesses and personal emergencies. The course director encourages partners for learning exercises and presentations to promote peerto-peer learning. Page 7 of 14 Methods in Health Services and Outcomes Research PHMS-702 Student Evaluation The components of student evaluation are: 1. Participation in classroom discussions. This component is evaluated using the following rubric and is applied to each student in each class. If a student is absent from class without prior arrangement with the course director, the student’s score for that class is 0.

Final exam. The final exam consists of questions about a published article and is distributed in class 14. The final is a take-home exam and is due back within five days following class 14. (20% of final grade) Page 10 of 14 Methods in Health Services and Outcomes Research PHMS-702 The following are intended to allow flexibility for busy students, while maintaining a sense of fairness to students who complete projects in a timely manner. Excused absences and assignment due dates All assignments must be completed and turned in on their assigned date and time. In the case of an excused absence from a class, arrangements with the course director must be made to submit the assignments for the class prior to the class or on an agreed-upon due date. Late assignments and penalties Assignments are considered late if turned in after 4:00 PM of the day following the assigned due date or other agreed-upon due date previously arranged with the instructor. Late assignments are penalized 10 points or 10 percentage-points, whichever is applicable, for each 24-hour delay. If an assignment is late by more than 48 hours, it is not accepted and receives a failing grade. Example: An assignment has an assigned due date of Thursday, October 5th. If it is turned in at 3:00 PM on Friday, October 6th, there is no penalty. If turned in at 5:00 PM on Friday, October 6th, the grade for the assignment is lowered 10 points or 10 percentage-points, whichever is applicable. If at 4:15 PM on Saturday, October 7th, the grade is lowered 20 points or 20 percentage-points, whichever is applicable. After 4:00 PM on Sunday, October 8th, the assignment receives a zero. Grading The components of student evaluation are weighted as follows: 1. 2. 3. 4. 5.

More information is located at http://www.louisville.edu/student/dev/drc/ Academic Honesty Students are required to comply with the academic honesty policies of the university and School of Public Health and Information Sciences. These policies prohibit plagiarism, cheating, and other violations of academic honesty. More information is located at https://docushare.louisville.edu/dsweb/Get/Document10846/SPHIS+Policy+on+Student+Academic+Honesty+Rev+3.pdf. Course instructors use a range of strategies (including plagiarism-prevention software provided by the university) to compare student works with private and public information resources in order to identify possible plagiarism and academic dishonesty. Comparisons of student works require students to submit electronic copies of their final works to the plagiarism-prevention service. The service delivers the works to instructors along with originality reports detailing the presence or lack of possible problems. The service retains copies of final works and may request students’ permission to share copies with other universities for the sole and limited purpose of plagiarism prevention and detection. Page 12 of 14 Methods in Health Services and Outcomes Research PHMS-702 In addition instructors provide the opportunity for students to submit preliminary drafts of their works to the service to receive reports of possible problems. Such reports are available only to the submitting student. Copies of preliminary drafts are not retained by the service.

Measuring Health: A Guide to Rating Scales and Questionnaires, 3rd Edition. New York: Oxford University Press, 2006. This is a gold standard reference for assessing content and psychometric properties of healthrelated questionnaires for research. It deals with issues of which questionnaires might be used for a given research project. This is an expensive text, but worthwhile for students interested in measurement. NOTE: On reserve in HSC Kornhauser Library Iezzoni, Lisa I (Ed.). Risk Adjustment for Measuring Health Care Outcomes, 3rd Edition. Chicago Ill: Health Administration Press, 2003. This text is the most readable book about the technical aspects of health services and outcomes research methods that the course director has found to date. It deals with issues of how one might conduct the HSR research design and analysis processes. Probably too advanced for most students at this entry-level course. Devellis, R. F. Scale Development: Theory and applications, 2nd Edition. Thousand Oaks: Sage Publications, 2003. Good reference for details on psychometrics. NOTE: On reserve in HSC Kornhauser Library Cramer JA., Spilker B. Quality of Life and Pharmaco-Economics: An Introduction. Lippincott – Raven, Philadelphia, 1998.
