The pilot, clinic and classmates are composite and described by role; the methods sources cited are real.
The Failure as I Presented It
Our pilot ran at one clinic before the network-wide study was designed. Sixteen clinicians were randomized, eight to offer same-day insertion and eight to schedule insertion at a second visit as usual. The outcome was completed insertion within 30 days. In the first month the intervention group's completion was far ahead. By week six the gap had nearly closed. When we looked, about a third of the control clinicians' patients who requested a device had been placed that same day by an intervention clinician, often after a medical assistant mentioned that "Dr. R. can do it now." I described this to the seminar as noncompliance and asked how to enforce assignment.
Moment One: A Clinic Manager on Shared Staff
A classmate who manages a family medicine clinic answered first, and her answer reframed the problem. In her clinic, medical assistants rotate among clinicians every session, the device supply cart sits in one shared procedure room, and front-desk staff book whichever clinician has a free slot. Nothing about the clinic is divided by clinician. A same-day service, she said, is a clinic workflow, not a clinician behavior, and the staff who carry that workflow cannot be randomized clinician by clinician. What I had called noncompliance was the clinic doing what clinics do with a better option once they have one.
I had randomized clinicians, but the intervention was delivered by a medical assistant, a supply cart and a booking template, none of which belonged to any one clinician.
That is contamination in the textbook sense, and the methods literature names it as the standard reason to randomize at the cluster level when an intervention operates through shared staff or settings (Hemming et al., 2015). I had read that sentence before the pilot and not recognized our clinic in it.
Moment Two: A Classmate on What Patients Experienced
A second classmate, a nurse in a school-based health center, raised something I had not considered as a finding at all. Patients of control clinicians who were sent down the hall met a second clinician, had a second counseling conversation and sometimes waited an hour. She asked whether we had any measure of how those patients felt about being moved. We did not. If the study had measured counseling experience, the walked patients might have rated it lower, and that would have mattered for a service whose value depends on patients feeling free to choose, given the history of long-acting methods being pressed on some groups of women (Gubrium et al., 2016).
Moment Three: The Instructor's Question
The instructor then asked what the control condition had been designed to be. I said "usual care." He asked what usual care was in a clinic where same-day insertion was available two doors away. I had no answer. Once some clinicians at a site can insert the same day, a two-visit pathway is no longer usual care at that site; it is a deliberate refusal of an available service, which no clinician or medical assistant could reasonably be expected to maintain. The control condition I designed did not exist in practice.
My Revised View
I came in thinking the clinicians had failed the design. I now think the design failed the clinic. Three things changed in my plan. The unit of randomization became the clinic, because that is where the intervention lives. The comparison became time, with clinics crossing over in a randomized order, so that a control clinic is one that genuinely does not yet offer the service (Hussey & Hughes, 2007). And counseling experience became a measured outcome rather than an assumption, because moving patients around to deliver a service can change how they experience it.
I also changed how I think about compliance in a trial. When participants consistently depart from an assigned condition in the same direction, the departure is information about the intervention. In our pilot, staff moved patients toward same-day insertion because they saw it as better care. That is evidence the service is acceptable to staff, which the stepped-wedge study can now use as an assumption rather than a hope.
What I still have to work out is how the larger study will recognize contamination of a different kind: patients from a clinic that has not yet crossed over traveling to one that has. The analysis plan in the next unit will need a way to count requests by the clinic where the patient asked, not where the device was placed.

HS840 Unit 7 instructions, in plain terms
Unit 7 typically asks learners to reflect on a live seminar discussion of a research design problem, often one from their own work, and explain how their understanding changed. Most run two or three pages, written as I. The reflection should state the learner's starting view, describe the specific contributions that challenged it and show how the learner's plan changed as a result. Instructors expect course vocabulary, such as contamination or unit of randomization, used accurately. Classmates should be described by role. Sources that explain the concepts raised are usually expected. Many prompts ask learners to finish by naming a question they still need to resolve, which carries the reflection into the next unit's work.
How this HS840 Unit 7 example is built
The opening section describes the pilot's design, outcome and the narrowing gap, and quotes the writer's question about enforcing assignment. Moment one records the clinic manager's account of shared staff and supplies, the highlighted sentence about who actually delivered the intervention and a citation naming contamination as the reason for cluster randomization. Moment two brings the school nurse's question about moved patients and links it to the coercion concern. Moment three gives the instructor's question about usual care. The revised view lists three changes: clinic as the unit, time as the comparison and counseling experience as an outcome. A final paragraph rethinks compliance and names the problem of patients traveling between clinics.
HS840 Unit 7 rubric: what earns full points
Reflections in a research methods course are commonly evaluated on the depth of change described, accurate use of methods concepts, integration of sources, connection to the learner's own study and writing quality. Depth earns the most when the reflection shows a specific belief replaced by a specific new understanding, with the cause identified. Methods concepts must be used correctly; misusing terms like contamination or confounding costs points. Integration rewards citing literature that explains the concepts the seminar raised. Connection to the learner's study is scored when the reflection lists concrete design changes. Writing points cover first-person clarity, organization by moments and APA format. A reflection that only summarizes the session tends to score low.
Common HS840 Unit 7 mistakes, and how to avoid them
Weak reflections retell the session but never pin down which belief moved. Another problem is blaming participants for a design failure, as this writer first did, and never examining the design itself. Some learners use methods terms loosely. Others name classmates or share identifying workplace details. A reflection that ends without a revised plan or a remaining question misses the link to later units. If your seminar discussed a different design problem, such as a survey with low response or a pilot with too few participants, send a short account of the problem and what classmates said, and we can write the reflection around the turning points in your plan.

HS840 Unit 7 questions, answered
Does the failed design have to be my own?
No. A workplace project, a published study that reported null results, or a case your instructor supplied would each serve. The requirement is enough design detail to diagnose the failure. Null or abandoned studies often make the richest cases. The sample's pilot is composite, built from common failure patterns, and described as though the writer had been involved.
How technical should a seminar reflection be?
Technical enough to use the course's methods vocabulary correctly, and personal enough that a reader watches your view shift. The sample names contamination, the unit of randomization and the control condition precisely, while keeping a first-person voice. A reflection that reads like a methods textbook has lost the reflective element; one without the vocabulary has lost the course.
Where can I find a free HS840 Unit 7 sample paper?
The full Unit 7 seminar reflection is shown here, tracing how a failed clinician-randomized pilot of same-day contraception led to a clinic-level stepped-wedge design.
What is contamination in a trial?
It happens when people in the control condition receive some of the intervention, often through shared staff or settings, which shrinks the measured difference between groups.
Should a reflection discuss patients' experience if the seminar was about design?
Yes, when it arises from the design. Moving patients between clinicians was a design consequence, and the sample adds counseling experience as an outcome because of it.
