The Orientation Log (O-Log)

The O-Log is a 10-item standardized tool for measuring orientation to time, place, and situation in patients recovering from acquired brain injury. It differs from the informal "person, place, and time" questions used at the bedside in an important way: it uses a structured cue progression and produces a score you can track over time. This makes it possible to document orientation not just as "oriented x3" or "not oriented," but as a number that reflects improvement or decline across sessions.

Target Population

Patients with acquired brain injury — TBI, CVA, tumor, infectious disease, or degenerative disorders — who are following commands and have a reliable response mode. A reliable response mode can be verbal, but can also be pointing, nodding, or eye gaze if consistently established. The O-Log cannot be used with patients who do not have a reliable way to communicate a response.

Appropriate for patients who have emerged from coma and are beginning to interact with their environment — roughly RLAS V and above, or equivalent on other scales. If the patient cannot follow a two-step command or cannot communicate a yes/no reliably, use a consciousness-level assessment (CRS-R, SECONDs, or CNC) first.

Domains and Items

The O-Log assesses 10 questions across three domains:

• Time (5 items): year, month, day of the month, day of the week, approximate time of day

• Place (3 items): country, state/region, type of facility (hospital)

• Situation (2 items): approximate length of stay, reason for admission

The situation domain is what sets the O-Log apart from informal orientation questioning. Knowing why they are here and how long they've been here requires a level of contextual awareness and memory consolidation that simple "time and place" questions don't test.

Scoring

Each item is scored on a 0–3 scale based on how much cueing the patient required:

• 3: Spontaneous and correct response with no prompting

• 2: Incorrect spontaneous response but correct with a logical cue (e.g., for place: "This is a place where doctors and nurses work")

• 1: Incorrect spontaneous and cued response, but correct with multiple choice or phonemic cue (e.g., offering three months to choose from)

• 0: Incorrect despite all cueing, inappropriate response, or unable to respond

Total possible score: 30 points. Higher scores indicate better orientation.

If the patient cannot respond verbally, some items can be answered via pointing, nodding, or eye-gaze with appropriately structured choices — document any modifications to standardized administration.

Score Interpretation

There are no formal diagnostic cutoffs for the O-Log, but context matters: most patients still in post-traumatic amnesia will score below 25. A score improving from 14 → 19 → 24 across a week of sessions is clinically meaningful even if it doesn't cross a threshold.

Use the score in combination with your clinical observation. A patient who scores 28 out of 30 but doesn't know why they're in the hospital (situation domain) may have a different presentation than one with a more evenly distributed loss across all three domains.

How to Use It Clinically

Administer at the beginning of each session as a brief orientation check rather than a formal standalone evaluation — it takes 3–5 minutes. The cue progression gives you useful information: does the patient know the answer spontaneously, or only when prompted? That distinction matters for treatment planning and documentation.

Document both the total score and any notable patterns — which domain is lowest, whether cueing is effective, whether the patient accepts orientation feedback or confabulates. Orientation to situation often improves last; anticipate this when communicating progress to families.
