Faculty
Damon Scales Tim Watkins Sibel Kiran Begum Ergan (TA) Refika Ersu (TA) Welcome to Level 2! This course is an extension of what you learned in Level 1, but it will also introduce you to many new topics. The course is taught in a very interactive fashion – the lectures will be short and we expect you to ask and answer questions during all of the sessions. The course has 4 major goals:
(1) To build on the principles of clinical research and epidemiology you learned in the introductory course,
(2) To provide you with additional tools to critically appraise the literature using principles of clinical epidemiology,
(3) To discuss your clinical research proposal using a scholarly approach (4) To enhance your research communication skills.
In addition to the large group sessions, there will be various types of smaller group sessions:
Design Groups Meet: you will have time to work on your personal research project – you should at least bring one or two ideas for projects to work on at the course. The instructors will work with you in small groups to make improve your proposals. Design Groups Present: You will present your work in progress and get feedback from your colleagues. Discuss Paper: Your group will have 30 min to discuss the questions posed, then faculty will join for another 30 min to help with the discussion. If there is an article that you find interesting that covers the diagnosis, prognosis, therapy, or surveys of attitudes in pulmonary or critical care medicine, bring it along and we can consider using it to teach from at one of the sessions.
What you need to do before you come to the course 1) Read the original articles Paper 1 through Paper 5, pay more attention to methodology and
results than to introduction and discussion. 2) Do the Homework for these sections – we will review these together so don’t worry if there
are questions you can’t answer. 3) Send us the research question or questions that you will be working on during Level 2.
Please send this in a word document to Damon ([email protected]) as soon as possible before the course starts.

Course Outline
1) Elements of a research proposal This module will orient you to the basic
elements of well written research proposal
- Research question - Hypotheses
- Study design - Study population
- Variables and measurements
- Sample size - Data analysis
- Limitations - Implications
2) Feasible study designs for limited funds Good research is not necessarily expensive – in this module you
will learn how to get the most out of the lease expensive study designs and methods.
- Surveys
- Chart review
- Secondary data analyses of existing databases
3) Diagnosis This module will take the student through the concepts necessary to understand how diagnostic
tests are evaluated and how information about test performance is applied at the bedside. Read the attached
article and homework for this section.
- How accurate is this test? All around the 2x2 table: sensitivity, specificity, accuracy, predictive values.
ROC and its area as single overall measure of test discrimination.
- If doctors think in terms of predictive values, why are tests reported as sensitivity and specificity?
- From information to decisions: how accurate a test needs to be depends on the decision.
- Evaluating studies of diagnostic tests
- Generalizability expertise and experience of test setting
spectrum bias
- Chance with particular reference to the confidence interval around zero and 100%
- How to evaluate tests when there is no criterion standard or when continuous results are provided. Categorical results: kappa and measures of inter-observer variability.
Continuous results: Bland-Altman plots.

4) Prognosis Making prognoses is an important and difficult clinical task. This module will teach you the basic
concepts behind prognostication, how to use prognostic data, and the pitfalls of prognostic studies. Read the
attached article and homework for this section.
- Many different types of prognostic information available to clinicians: Disease staging (cancer)
Risk models (APACHE)
Clinical prediction rules
- Differences between clinical prognosis and risk adjustment.
- What is the role of confounding and causal inference in studies of prognosis? Differences between multivariate modeling when the goal is generate an unbiased estimate of one of the
coefficients (that is, when the goal is determine the unconfounded “effect” of the exposure) versus multivariate
modeling for prediction when the goal is a model that is accurate (calibration and/or discrimination) and
generalizable.
- Identifying relevant prognostic variables.
- Generalizability - a key factor in assessing the use of prognostic data.
- Expressing prognosis Rates, relative rates, hazards and hazard ratios.
Median survival
Probability of event
5) Assessing attitudes and behaviors Understanding patients and clinician’s knowledge, attitudes, and behavior
is an important area of research. Read the attached article and homework for this section.
- Survey design and validation
- Existing instruments versus developing your own
- Available population versus target population
- Response rates and bias
- Limitations of cross-sectional data and associations
6) Therapy Ultimately, questions about therapy are questions about causation. Does the treatment cause the
improved outcome? Causality is hard to prove and this module will teach you how to think about studies
about treatment. Read the attached article and homework for this section.
- Inference from randomized experiment What is the purpose of randomization?
Reducing confounding to chance.
The purpose of Table 1. Do the P values in Table 1 mean anything?
What is the purpose of blinding? To reduce bias.
Do randomization and blinding serve any role in enhancing generalizability?
What are the limitations of experiments? Efficacy and Effectiveness
- Inference from observational studies What are the advantages of observational studies in evaluating medical treatments?
Potential for confounding - particularly confounding by indication.
Advanced techniques for addressing confounding in observational studies of med ical treatments.
Confounder scores
Propensity scores

Dr Timothy Watkins holds an undergraduate degree in Biology from Ohio University, a medical degree from Ohio State University and a Master’s degree in Public Health from the University of Washington. Dr. Watkins performs clinically-oriented translational research, studying outcomes following critical illness and injury, examining specifically how blood product transfusions might contribute to adverse clinical outcomes. His research areas of interest include examining the clinical and biologic relationships between blood product transfusions and the development of lung injury, sepsis, and multiple organ failure. He is focusing on elements of blood product processing, storage, and even blood donor health-related factors in order to identify mechanisms to improve transfusion safety in critically ill and injured populations. These groups seem especially vulnerable to transfusion-associated complications.
