Four of Twelve Sessions: Nonadherence or a Broken Plan?
Ms. T is 54 years old, six weeks after a STEMI treated with PCI, enrolled in phase II cardiac rehabilitation. She has attended 4 of 12 scheduled sessions. She works two jobs and cares for her mother, who has dementia. She stopped her statin after two weeks because of muscle aches and continues to smoke about half a pack a day. "I'll quit when things calm down," she says. She reads at roughly a sixth-grade level and uses her phone for everything. Her PHQ-2 score is 3. She says she wants to "get back to normal" and that the exercise "is boring." Her LDL is 118 mg/dL, BP 138/84, and she has gained 3 kg since discharge.
1. Reframe this presentation as a behavior-change and systems problem. What do you prioritize, and why in that order?

Reframe: the label "nonadherent" is doing no work here. She has three jobs, a dependent parent, a positive depression screen, low health literacy, and a regimen built for someone with more time. Attendance problems are usually design problems before they are motivation problems.
Priorities:
- Safety first - the statin. Muscle symptoms after statin initiation need evaluation (CK, symptoms, timing, alternatives such as a different statin, lower dose, or non-statin therapy). She should not simply remain off it, and you should not tell her to restart it yourself. Route this to her prescriber within days.
- Depression. PHQ-2 of 3 is a positive screen; administer PHQ-9 and refer for assessment. Untreated depression predicts dropout, poor self-care, and worse cardiac outcomes. It also explains some of the "boring" and the fatigue.
- Tobacco. The highest-yield modifiable risk in a post-MI patient. "When things calm down" is a real barrier, not an excuse; treat it with concrete support rather than a lecture.
- Access and scheduling. Two jobs plus caregiving means transport and timing are the binding constraints.
- Exercise variety. Boring is fixable and worth fixing, but it is not the top of the list.
Reasoning: sequencing matters because tackling exercise variety while she is depressed, smoking, off her statin, and unable to attend would be optimizing the least important variable.
2. Design a concrete plan using a specific behavior-change framework, with two or three measurable goals.

Framework: motivational interviewing for agenda setting, the 5 A's for tobacco, and teach-back for literacy.
MI opening: "You told me you want to get back to normal. What would that look like on a normal Tuesday?" Reflect, summarize, and let her choose the first target rather than assigning three at once. Roll with resistance on tobacco - arguing about "when things calm down" will end the conversation.
Plan:
- Attendance goal: attend at least 8 of the next 12 sessions, using two fixed evening slots and a home video option for the weeks she cannot travel. Phone reminder 24 hours before; text-based check-in.
- Tobacco goal: agree to a quit date within four weeks, with nicotine replacement or varenicline arranged through her prescriber and a quitline referral; reduce to a set number per day before the quit date if she prefers a stepwise start. Use the 5 A's to ask, advise, assess, assist, arrange.
- Statin goal: a message to her prescriber within one week about muscle symptoms, with a follow-up appointment to review options; document her understanding of why the statin matters post-STEMI.
Teaching method: sixth-grade language, pictures, and teach-back - "Tell me in your own words what you will do if your legs ache again." Written plan on her phone with a photo of the schedule, not a dense handout.
Reasoning: each goal is observable, time-bound, and tied to something she already values, and none depends on her suddenly having more hours in the day.
3. What outcomes do you track, on what schedule, and how do you document the behavioral plan?
Read the worked answer
Process measures (weekly):
- Sessions attended versus scheduled; mode and duration; reason for each missed session (this is program-level data, not just hers).
- Tobacco use, quit attempts, and pharmacotherapy use.
- PHQ-9 at intake and at 6 weeks.
Outcome measures (baseline, 6 weeks, discharge):
- 6-minute walk distance with oxygen saturation and perceived exertion.
- BP, resting heart rate, weight and waist circumference.
- LDL and medication status, confirmed with the prescriber.
- Self-efficacy or readiness rating for exercise and smoking, scored simply and repeated.
Follow-up schedule: phone contact at 1 week (attendance and statin message to prescriber), clinic review at 2 weeks (goals, PHQ-9, tobacco plan), then weekly contact through the block. Escalate to behavioral health promptly if PHQ-9 is elevated or if hopelessness emerges.
Documentation:
- Her own words about what she wants, quoted.
- The agreed goals, who is responsible for each, and the date to review them.
- Teach-back result - did she accurately restate the plan?
- Referrals made (prescriber, behavioral health, quitline) with dates and responses.
- The reason for any modification, so the next clinician does not mistake a redesigned plan for noncompliance.
Reasoning: tracking attendance without tracking why it failed turns a fixable design problem into a character judgment, and the documentation should make that distinction explicit for the next clinician.
