Many clinicians find insomnia frustrating to evaluate and treat.
Patients often present after trying multiple medications or referrals without much improvement. But in clinical practice, most insomnia cases come down to a handful of underlying factors. Once you know what to look for, the evaluation becomes surprisingly straightforward.
In this article, I’ll walk through a practical clinical workflow clinicians can use to evaluate insomnia in everyday practice.
This post accompanies Part 2 of my 3-part insomnia series for clinicians, where I walk through the exact evaluation process I use in my clinic.
Clinical Quick Guide: How to Evaluate Insomnia
A structured insomnia evaluation helps clinicians identify the drivers of sleep disruption before jumping to treatment.
A practical clinical workflow includes five steps:
1. Clarify the sleep complaint
Determine whether the patient has difficulty falling asleep, staying asleep, early morning awakening, or non-restorative sleep.
Assess duration, severity, and daytime functioning.
2. Assess sleep schedule and circadian timing
Review bedtime, wake time, schedule variability, light exposure, and social or work schedules that influence circadian rhythms.
3. Evaluate sleep drive and behavioral factors
Assess time spent in bed, napping, caffeine intake, alcohol use, and evening screen exposure.
4. Screen for contributing conditions
Consider medical, psychiatric, and sleep disorders that commonly present with insomnia, including:
- obstructive sleep apnea
- restless legs syndrome
- circadian rhythm disorders
- anxiety and depression
- medication effects
5. Identify patterns that guide treatment
Most insomnia cases involve multiple contributing factors rather than a single cause.
When clinicians evaluate sleep systematically, the treatment path becomes clearer.
Watch: Clinical Workflow for Evaluating Insomnia
In this video, I walk through the exact workflow I use in my clinic to evaluate insomnia, including key questions that often reveal the underlying causes of sleep problems.
A Lesson From Learning the Sitar
In my first year of university, I decided to learn the sitar.
I showed up to my teacher’s house for my first lesson, left my shoes at the door, sat cross-legged on her basement floor, and eagerly waited to see what would happen next.
Across from me sat her 10-year-old musical prodigy daughter with a tabla, ready to play.
My teacher began singing sa-re-ga-ma while her tiny dog yapped and two bunnies watched from a cage in the corner.
On the surface it looked chaotic.
But I had learned piano as a child.
I understood scales, music theory, and the process of practicing a phrase until your fingers stopped thinking about it.
The sitar was a completely different instrument, but the foundation was already there.
What looked chaotic had an underlying structure.
I often think about this when clinicians approach insomnia.
Many assume insomnia is outside their wheelhouse, it’s either too behavioral, too specialized, or too time-consuming.
So the default approaches often become:
- referring patients out
- cycling through sleep medications
- revisiting the same sleep complaint repeatedly
But most clinicians already have the core skills needed to evaluate insomnia.
If you can take a thorough clinical history, recognize patterns, and perform a thoughtful evaluation, you already have the foundation.
Insomnia simply requires a clear framework layered on top of those skills.
A Clinical Case: When the Cause of Insomnia Is Missed
One patient illustrates how easily important contributors can be overlooked.
She was in her early forties and had been referred for insomnia after trying several sleep medications, including zolpidem.
During the evaluation I asked a question I now ask nearly every insomnia patient:
“Tell me about your sleep environment.”
She lived in a small San Francisco studio apartment and had been sleeping in a closet because it was the only separate room.
The room was poorly ventilated and very hot at night.
We moved her bed closer to a window.
Her sleep improved almost immediately.
But that wasn’t the whole story.
Further evaluation revealed subtle symptoms of obstructive sleep apnea that had never been assessed.
Testing confirmed sleep apnea, and combined with behavioral sleep interventions she eventually tapered off zolpidem and began sleeping better than she had in years.
What stood out about this case was that several clinicians had treated her insomnia, but no one had systematically evaluated the underlying contributors.
Insomnia rarely has a single cause.
It’s usually a pattern across multiple factors.
The FEEM Framework for Evaluating Insomnia
After evaluating many insomnia patients, I noticed that contributing factors usually fall into four categories.
I use the acronym FEEM to remember them.
Food
Dietary contributors to poor sleep may include:
- caffeine
- alcohol
- reflux from late meals
- low ferritin contributing to restless sleep
Environment
Sleep environment factors include:
- bedroom temperature
- light exposure
- noise
- inconsistent sleep schedule
- sleep hygiene habits
Emotional factors
Psychological contributors include:
- anxiety
- rumination
- trauma
- conditioned hyperarousal around sleep
Medical conditions
Medical contributors commonly include:
- obstructive sleep apnea
- restless legs syndrome
- circadian rhythm disorders
- medication effects
Evaluating these categories systematically often reveals the pattern driving insomnia.
Questionnaires That Simplify Insomnia Evaluation
Standardized questionnaires can make insomnia assessments much more efficient.
Helpful tools include:
- Insomnia Severity Index (ISI)
- Epworth Sleepiness Scale
- GAD-7
- PHQ-9
- Mood Disorder Questionnaire
Many clinicians also have patients complete a sleep history form or sleep diary before the visit, which allows appointment time to focus on clinical decision-making.
The American Academy of Sleep Medicine provides free templates that work well in practice.
Understanding the Patient’s Relationship With Sleep
Sometimes the most important perpetuating factor in insomnia is not behavioral or medical.
It is the patient’s relationship with sleep itself.
A helpful interviewing framework is FIFE:
Feelings — How do you feel about your sleep problem?
Ideas — What do you think is causing it?
Functioning — How is it affecting your daily life?
Expectations — What are you hoping treatment will accomplish?
These questions often reveal beliefs that reinforce insomnia, such as fear of not sleeping enough or pressure to achieve perfect sleep.
Understanding these beliefs is often one of the most important parts of an insomnia evaluation.
What Clinicians Often Notice
Once clinicians start evaluating insomnia systematically, patterns begin to emerge.
Instead of insomnia feeling mysterious, clinicians start to recognize:
- environmental contributors
- behavioral sleep patterns
- medical sleep disorders
- cognitive or emotional drivers
Once those factors are identified, treatment becomes far more targeted.
Often the interventions themselves are surprisingly simple.
Frequently Asked Questions About Evaluating Insomnia
What is the first step in evaluating insomnia?
The first step is clarifying the patient’s sleep complaint and determining whether the issue involves sleep onset, sleep maintenance, early awakening, or non-restorative sleep.
What conditions should clinicians screen for?
Common contributors include sleep apnea, restless legs syndrome, circadian rhythm disorders, anxiety, depression, and medication effects.
What questionnaires are useful for insomnia assessment?
Common tools include the Insomnia Severity Index, Epworth Sleepiness Scale, GAD-7, PHQ-9, and sleep diaries.
Do clinicians need specialized sleep training to evaluate insomnia?
Most clinicians already have the foundational skills. A structured framework for evaluating sleep can make insomnia assessments far more manageable.
