What is the BIMS (Brief Interview for Mental Status)?
The Brief Interview for Mental Status (BIMS) is a standardized cognitive screening tool used primarily in nursing homes and long-term care facilities. It was developed as part of the Minimum Data Set (MDS) 3.0 to provide a quick, reliable assessment of cognitive function in residents.
The BIMS takes only 3-5 minutes to administer and assesses two key cognitive domains: temporal orientation (knowing the year, month, and day of week) and short-term memory (recall of three words with and without cues). It is designed to be administered directly to the resident whenever possible.

How to Administer the BIMS
Administration Steps:
- Introduce the Test: "I would like to ask you some questions about memory and thinking."
- Present Three Words: Say "I am going to say three words for you to remember: SOCK, BLUE, BED. Please say them back to me."
- Ask Orientation Questions: Ask about year, month, and day of week
- Test Recall: Ask resident to recall the three words. If unable, provide category cues:
- Sock - "something to wear"
- Blue - "a color"
- Bed - "a piece of furniture"
- Score Each Response: Use standardized scoring criteria
Key Administration Points
- • Administer in a quiet environment free from distractions
- • Speak clearly and at a moderate pace
- • Allow adequate time for responses
- • Only provide cues for recall if initial recall fails
- • Document the assessment conditions
When to Use the BIMS
Required Assessment Times
- • Admission to nursing facility
- • Annual reassessment
- • Quarterly assessment (MDS schedule)
- • Significant change in status
- • Return from hospital
Clinical Applications
- • Baseline cognitive assessment
- • Track cognitive changes over time
- • Identify need for further evaluation
- • Care planning decisions
- • Quality indicator reporting
Important Limitations
- • BIMS is a screening tool, not a diagnostic test for dementia
- • A low score indicates need for further evaluation, not a dementia diagnosis
- • Factors like hearing loss, language barriers, or acute illness can affect scores
- • Cannot differentiate between types of dementia
BIMS Scoring System
A. Temporal Orientation (6 points)
Year (0-3 points)
3 = Correct, 2 = Off by 1 year, 1 = Off by 2-5 years, 0 = Off by >5 years
Month (0-2 points)
2 = Correct, 1 = Off by 1 month, 0 = Off by >1 month
Day of Week (0-1 point)
1 = Correct, 0 = Incorrect
B. Three-Item Recall (6 points)
Each Word: SOCK, BLUE, BED (0-2 points each)
2 = Recalled without cue, 1 = Recalled with category cue, 0 = Unable to recall
Category Cues
Sock = "something to wear", Blue = "a color", Bed = "a piece of furniture"
Total BIMS Score:
BIMS = Orientation Score (0-6) + Recall Score (0-6) = 0-15 points
Clinical Evidence & Validation
Psychometric Properties
Reliability
- • Inter-rater reliability: Kappa = 0.80-0.90 (excellent)
- • Test-retest reliability: ICC = 0.85-0.92
- • Internal consistency: Cronbach's α = 0.79-0.85
Validity
- • Concurrent validity: Strong correlation with MMSE (r = 0.82-0.91)
- • Sensitivity: 81% for detecting moderate/severe impairment
- • Specificity: 88% for excluding cognitive impairment
Development History
BIMS vs Other Cognitive Screens
| Feature | BIMS | MMSE | MoCA | CAM |
|---|---|---|---|---|
| Purpose | Cognitive screening | Cognitive screening | MCI detection | Delirium detection |
| Time to Administer | 3-5 min | 10-15 min | 10-15 min | 5-10 min |
| Score Range | 0-15 | 0-30 | 0-30 | Yes/No |
| Training Required | Minimal | Moderate | Moderate | Moderate |
| Cost | Free | Licensed | Free | Free |
| Best Setting | Nursing Home | Outpatient/Research | Memory Clinic | Hospital |
BIMS Advantages
- • Very quick to administer (3-5 minutes)
- • No special training or equipment needed
- • Free to use - no licensing fees
- • Required for MDS 3.0 in nursing homes
- • Specifically designed for LTC residents
- • Can be administered by various disciplines
BIMS Limitations
- • Only assesses two cognitive domains
- • Cannot differentiate dementia types
- • May miss mild cognitive impairment
- • Not designed for delirium detection
- • Requires verbal responses
- • Not validated for acute care settings
Clinical Decision-Making Guide
Score 13-15: Cognitively Intact
Clinical Implications
- • Patient can likely participate in care decisions
- • May be appropriate for self-administration of medications
- • Can provide reliable self-report for assessments
- • Should be included in care conferences
Follow-up Actions
- • Routine reassessment quarterly or with status change
- • Document as baseline for comparison
- • No immediate cognitive intervention needed
- • Continue standard activity programming
Score 8-12: Moderate Impairment
Clinical Implications
- • May need assistance with complex decisions
- • Supervision likely needed for medication administration
- • May have difficulty with new information
- • Include family/guardian in care planning
Follow-up Actions
- • Consider MMSE or MoCA for detailed assessment
- • Rule out reversible causes (depression, medications)
- • Evaluate decision-making capacity
- • Implement memory aids and cues
Score 0-7: Severe Impairment
Clinical Implications
- • Requires surrogate decision-maker
- • Full supervision for safety needed
- • May not reliably report symptoms
- • High risk for behavioral symptoms
Follow-up Actions
- • Comprehensive dementia workup if new finding
- • Assess for delirium superimposed on dementia
- • Update goals of care with family
- • Consider palliative care consultation
Expert Administration Tips
Do's
- ✓ Ensure the environment is quiet and free of distractions
- ✓ Make sure resident has hearing aids/glasses if needed
- ✓ Speak clearly and at a moderate pace
- ✓ Allow sufficient time for resident to respond
- ✓ Repeat the three words clearly before moving to orientation
- ✓ Provide category cues exactly as specified if recall fails
- ✓ Score based on actual response, not what you think they know
Don'ts
- ✗ Don't give additional hints beyond specified cues
- ✗ Don't accept gestures or pointing for verbal items
- ✗ Don't allow family members to help with responses
- ✗ Don't rush through the assessment
- ✗ Don't change the order of items
- ✗ Don't substitute different words for the recall test
- ✗ Don't administer during acute illness or sedation
