Enter the scores for orientation, registration, attention, and recall into the calculator to determine the Brief Interview for Mental Status (BIMS) score. This calculator helps in assessing cognitive impairment.

BIMS Score Formula

The following formula is used to calculate the BIMS score:

BIMS = O + R + A + RC


  • O is the score for orientation (0-2 points)
  • R is the score for registration (0-1 points)
  • A is the score for attention (0-1 points)
  • RC is the score for recall (0-2 points)

To calculate the BIMS score, add the points scored in each of the four categories: orientation, registration, attention, and recall.

What is a BIMS Score?

The BIMS score is a quick screening tool used to assess cognitive impairment in older adults. It is part of the Minimum Data Set (MDS) for resident assessment in nursing homes. The BIMS score ranges from 0 to 15, with higher scores indicating better cognitive function. It is used by healthcare professionals to identify changes in cognitive status over time and to plan appropriate care.

How to Calculate BIMS Score?

The following steps outline how to calculate the BIMS Score:

  1. First, determine the score for orientation (O) between 0 and 2 points.
  2. Next, determine the score for registration (R) between 0 and 1 point.
  3. Then, determine the score for attention (A) between 0 and 1 point.
  4. After that, determine the score for recall (RC) between 0 and 2 points.
  5. Use the formula BIMS = O + R + A + RC to calculate the total BIMS score.
  6. Finally, compare the total BIMS score with the scoring guidelines to interpret the level of cognitive impairment.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Orientation (O) = 2 points

Registration (R) = 1 point

Attention (A) = 1 point

Recall (RC) = 2 points
