HMGT 307 at the University of Maryland Global Campus applies epidemiology to the work of healthcare managers. UMGC describes it as an overview of epidemiologic principles and tools applicable to decision making in healthcare, with a focus on integrative decision making.
The course combines numbers and judgment. Calculating a rate is the easy part; deciding what it says about a population, and whether a study's design can support a causal claim, is where many students lose marks.
It is also a hinge in the sequence: UMGC lists HMGT 307 as the prerequisite for HMGT 310, HMGT 320 and HMGT 335.

What HMGT 307 Covers
| Objective (UMGC wording, summarized) | What it means in practice |
|---|---|
| Apply descriptive epidemiology to planning, directing, controlling, organizing, staffing and financial management | Using measures of disease and health in a population to inform management choices |
| Critically evaluate factors that influence the health status of populations served | Looking at determinants such as age, behavior, environment and access to care |
| Distinguish among study designs for causal inference and sources of bias | Knowing what a cohort, case-control or cross-sectional study can and cannot show |
Key Concepts Explained
Incidence and Prevalence
Incidence counts new cases in a population over a period; prevalence counts all existing cases at a point or period. Incidence tells you about risk, prevalence about the burden on services.
Invented illustration: A clinic serves 2,000 patients. If 40 are newly diagnosed with a condition this year and 100 patients live with it in total, the incidence is 40 per 2,000 (2 per 100) and the prevalence is 100 per 2,000 (5 per 100). A manager planning capacity cares most about the prevalence.
Study Designs and Bias
Each design answers a different kind of question. Cross-sectional studies describe, case-control studies compare past exposures, and cohort studies follow groups forward. Randomized trials are strongest for causal claims. Name the likely biases, such as selection or recall bias, before accepting a conclusion.
From Evidence to Decision
A good answer moves from the measure to a management action, for example staffing, screening outreach or budget priority, and says what uncertainty remains.
Typical Assignments and How to Approach Them
UMGC's catalog does not list assessments, so this describes common work in an epidemiology course. Follow your own syllabus.
| Type | Tests | Approach |
|---|---|---|
| Rate and ratio exercises | Correct calculation | Write the formula, show each step and state the unit |
| Study design critique | Judging causal strength | Name the design, then the biases, then what conclusion is safe |
| Population health analysis | Applying data to a decision | Summarize the pattern, then recommend one management response |
A Weekly Study Routine
This is a suggested routine, not a UMGC requirement.
| Step | Action |
|---|---|
| 1 | Revise STAT 200 basics: proportions and reading tables |
| 2 | Learn each measure by its question: how many, how fast, how risky |
| 3 | Practice two calculations and explain each result in a sentence |
| 4 | Summarize one study design on a card with strengths and typical biases |
A Second Worked Example: Reading a Study
Interpreting a study is a skill you can rehearse. Take an invented example: a health system compares two groups of patients, those who attended a weekly self-management class and those who did not, and finds that class attendees had fewer emergency visits.
Before recommending that the system fund more classes, ask four questions. Who chose to attend? If healthier or more motivated patients self-selected, the difference may reflect them rather than the class. Was the comparison made at one point in time or over time? Which design was used? What else differs between the groups, such as age or income?
Model reasoning (invented): "The pattern is consistent with a benefit from the class, but a cross-sectional comparison cannot show that the class caused it. Selection bias is likely. A prospective cohort or a trial would give stronger evidence. Pending that, a manager could pilot the class in one clinic and track emergency visits before and after."
Notice that the answer neither dismisses nor accepts the finding. It states what is supported, what is not and what to do next. That balance is what instructors usually reward in this course.
What a Strong Answer Contains
- The measure named correctly, with its formula and unit.
- A statement of the population at risk (the denominator).
- A plain-language interpretation a non-specialist manager would understand.
- The limits of the data, including likely bias.
- A management action linked to planning, staffing or finance.
Checking Your Work Before Submitting
Re-run each calculation and check units, such as per 100 or per 1,000. Make sure your interpretation says who is included in the denominator and the time period. Ask whether you have claimed cause where the design supports only association.
Finally, confirm that each section ends with a link to a management decision, since that is what makes this an applied course.
Where Students Get Stuck
- Mixing up incidence and prevalence. Ask whether the cases are new or existing.
- Treating association as cause. Check design and confounding first.
- Calculations without interpretation. Always add what the number means for a manager.
- Ignoring the denominator. State who is at risk before dividing.
Study Tips for HMGT 307
- Make a one-page formula sheet with a worked example for each measure.
- Explain each study design aloud in plain language.
- Link every example to a management decision to match the course focus.

Frequently Asked Questions
UMGC lists HMGT 300 and STAT 200.
It uses basic rates, ratios and proportions, with the emphasis on interpreting them in a management context. Your STAT 200 knowledge helps.
Descriptive epidemiology describes who, where and when; analytic epidemiology tests why, using study designs that compare groups.
UMGC lists it as the prerequisite for HMGT 310, HMGT 320 and HMGT 335.
