Newly Diagnosed MS, Moderately Severe Depression, and a $600 Copay
Ms. L is a 34-year-old woman diagnosed with relapsing-remitting multiple sclerosis five months ago after a single relapse treated with IV methylprednisolone. She started an injectable disease-modifying therapy three months ago but estimates she has taken about half the doses, citing injection anxiety and "forgetting." Her PHQ-9 score is 17; she reports anhedonia, guilt, poor sleep, and says, "What's the point - I'll end up in a wheelchair like my aunt." She divorced eight months ago, has primary custody of two children (ages 6 and 9), and works variable evening shifts as a restaurant server. Her employer plan has a $4,000 deductible and the disease-modifying therapy copay is $600 per month. She reports heat sensitivity, urinary urgency, and fatigue that she attributes to "being a single mom." She has not told her supervisor about the diagnosis.
1. How should the case manager interpret the PHQ-9 score of 17 and what must happen next, given that fatigue and poor concentration also occur in MS?

A score of 17 falls in the moderately severe range and cannot be dismissed as "just MS." First, check item 9. Any positive response requires an immediate structured suicide risk screen (for example, the C-SSRS or ASQ) with direct questions about intent, plan, means, and protective factors, and escalation per protocol - not a routine referral. Second, separate depression from disease and treatment effects. Fatigue, poor concentration, and sleep disruption overlap with MS, but anhedonia, guilt, hopelessness, and her statement about ending up in a wheelchair point to a depressive syndrome; review for steroid-induced mood effects and other medications. Third, refer to behavioral health and notify the MS neurologist, since treating depression improves adherence, fatigue, and quality of life. Use the score as a baseline to repeat, not as a diagnosis. Document, communicate with the team the same day, and avoid the common error of attributing every symptom to multiple sclerosis.
2. Using motivational interviewing, how should the case manager address the missed injections and the cost barrier?

Motivational interviewing fits because she is ambivalent, not defiant. Open with agenda setting, then use OARS - open questions, affirmations, reflections, summaries - to elicit her own reasons. Reflect the ambivalence: "Part of you wants to stop feeling like a pincushion, and part of you is scared of what happens if you do nothing." Avoid the righting reflex; warning her about relapses tends to increase resistance. Explore the two barriers separately. Injection anxiety: ask what would make the injection more manageable - nurse-led teach-back, an auto-injector, a shorter needle, scheduling on a day off. Cost is often the real driver: $600 per month against a $4,000 deductible is unaffordable, so connect her with manufacturer copay assistance, disease-specific foundations, the plan's formulary alternatives, and insurance navigation through patient organizations. Ask permission before giving information, then ask what she makes of it. Close with a concrete plan she states herself - which days she will inject, whom she will call. Document her stated goal, not your recommendation.
3. What psychosocial, financial, and practical supports should be assessed and mobilized for this patient?
Read the worked answer
Map practical, emotional, and financial resources rather than asking only whether she has family. Practical: childcare during evening shifts and injections, transportation to appointments, a reliable refrigerator for medication storage, and whether intermittent leave or schedule accommodation is needed. Emotional: a divorce eight months ago removed a partner and possibly income; screen for isolation and for intimate partner violence, and ask who she would call at 2 a.m. Financial: deductible and copay exposure, potential disability benefits if she stops working, state pharmaceutical assistance, and whether the plan covers the therapy at all. Occupational: variable evening shifts disrupt sleep, and heat in a restaurant kitchen worsens Uhthoff symptoms - discuss cooling strategies, breaks, and whether to disclose under the ADA, which is her choice. Refer to a patient organization navigator, a social work consult for benefits, and peer support; isolation is itself a risk factor. Re-screen the PHQ-9 in four weeks and document referrals and follow-through.
