The Foundation

Why ICU Experience Matters for Psychiatry

In the ICU, every patient is a diagnostic puzzle. You can't simply prescribe and wait—you need to understand exactly what's happening physiologically, identify root causes, and intervene precisely. There's no time for trial-and-error when someone is critically ill.

After 19 years across 7+ ICU specialties—from trauma and burn units to cardiac surgery and ECMO—I developed a systematic approach to medical investigation that I now apply to psychiatric care. The methodology is the same: comprehensive assessment, systematic investigation, and targeted treatment based on findings.

Most psychiatric evaluations last 15-30 minutes and focus on symptom management. My approach starts with 75-90 minute evaluations that investigate the whole clinical picture—because psychiatric symptoms often have medical causes that standard evaluations miss.

The Discovery

The 40% Discovery That Changed Everything

When I transitioned to psychiatry, patterns emerged immediately. Patients on 4-5 psychiatric medications weren't getting better. Standard evaluation had missed:

  • Severe hypothyroidism causing 'treatment-resistant depression'
  • B12 deficiency so severe it mimicked schizophrenia
  • Sleep apnea causing anxiety and depression (80% undiagnosed rate)
  • Beta-blockers causing depression (medication side effect, not primary illness)
  • Iron deficiency causing fatigue misdiagnosed as depression

Research confirmed what I was seeing: up to 40% of patients with complex psychiatric symptoms have underlying medical causes. These aren't rare zebras—they're common, systematic failures in diagnostic investigation.

Qualifications

About the Credential: PMHNP-BC

I'm a board-certified Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC), which actually provides some advantages for comprehensive medical-psychiatric care:

  1. Broader medical scope: With dual specialization (psychiatric + primary care in progress), I can directly evaluate and treat medical causes.
  2. More time per patient: Nurse practitioners typically allocate more time per visit. My standard initial evaluation is 75-90 minutes.
  3. ICU diagnostic foundation: The diagnostic rigor comes from 19 years across 7+ ICU types.

Education

My Broader Clinical Training

Beyond psychiatric specialization, I'm completing Adult-Gerontology Primary Care Nurse Practitioner certification at Purdue University. I hold an MBA from UCLA Anderson School of Management, which informs how I think about practice systems, patient outcomes, and sustainable care models.
