Fill-in-the-Blank Template for History of Present Illness (HPI) in Altered Mental Status
The most effective HPI for a patient with altered mental status should follow a structured, comprehensive approach that addresses all key domains of cognitive and behavioral symptoms and their impact on daily function.
Chief Complaint
Patient is a [age]-year-old [gender] presenting with [duration] of altered mental status characterized by [specific symptoms: confusion/disorientation/lethargy/agitation/hallucinations/etc.].
Characterization of Symptoms
- Onset and progression: Symptoms began [abruptly/gradually] approximately [timeframe] ago and have [improved/worsened/fluctuated] since onset.
- Specific cognitive changes: Patient has demonstrated [memory problems/disorientation to time, place, person/difficulty with attention/language difficulties/impaired reasoning].
- Behavioral changes: [Agitation/lethargy/inappropriate behavior/hallucinations/delusions/sleep-wake cycle disturbances].
- Level of consciousness: Patient has been [alert/drowsy/difficult to arouse/unresponsive].
- Fluctuation pattern: Symptoms [remain constant/fluctuate throughout the day/worse at night/"sundowning"].
Impact on Daily Function
- Activities of daily living (ADLs): Patient [is/is not] able to [dress/bathe/toilet/feed] independently.
- Instrumental activities (IADLs): Patient [is/is not] able to [manage medications/handle finances/prepare meals/use transportation].
- Safety concerns: [Falls/wandering/unsafe use of appliances/inability to recognize dangerous situations].
Associated Symptoms
- Neurological: [Headache/focal weakness/sensory changes/visual disturbances/seizure activity].
- Systemic: [Fever/chills/pain/shortness of breath/urinary symptoms/recent infections].
- Mood/psychiatric: [Depression/anxiety/paranoia/hallucinations/suicidal ideation].
Potential Triggers or Precipitating Factors 1
- Recent medication changes: [New medications/dose adjustments/missed doses/over-the-counter medications].
- Substance use: [Alcohol/recreational drugs/recent changes in use patterns/withdrawal].
- Recent procedures/hospitalizations: [Surgery/anesthesia/recent hospitalization/procedures].
- Environmental changes: [Recent relocation/unfamiliar surroundings/hospitalization].
- Metabolic factors: [Recent dietary changes/dehydration/electrolyte abnormalities].
Relevant Medical History
- Prior cognitive issues: [Baseline cognitive function/prior episodes of altered mental status/dementia diagnosis].
- Neurological conditions: [Stroke/seizures/head trauma/neurodegenerative disorders].
- Systemic conditions: [Diabetes/hypertension/renal disease/liver disease/cardiac disease/pulmonary disease].
- Psychiatric history: [Depression/anxiety/psychosis/substance use disorders].
Collateral Information 1
- Source of information: [Relationship to patient/reliability/frequency of contact].
- Baseline function: Patient's baseline cognitive status was [fully independent/mild impairment/moderate impairment].
- Timeline of changes: [Informant's description of onset and progression of symptoms].
- Recent life events: [Stressors/changes in living situation/loss of loved ones].
Risk Factors for Cognitive Decline 1
- Age-related: [Age/family history of dementia].
- Vascular risk factors: [Hypertension/diabetes/hyperlipidemia/smoking/obesity].
- Other modifiable factors: [Sleep disorders/hearing loss/social isolation/physical inactivity].
Medication Review
- Current medications: [Complete list with doses and schedules].
- High-risk medications: [Anticholinergics/benzodiazepines/opioids/sedatives/hypnotics].
- Adherence: [Patient's typical adherence pattern/recent changes].
Vital Signs and Physical Findings
- Vital signs: [Temperature/blood pressure/heart rate/respiratory rate/oxygen saturation].
- General appearance: [Level of distress/hygiene/nutritional status].
- Neurological findings: [Mental status exam findings/focal deficits/abnormal movements].
Assessment Tools Used 1, 2
- Cognitive screening: [Results of tools used: CAM/Richmond Agitation Sedation Scale/Glasgow Coma Scale].
- Delirium assessment: [Results of CAM/B-CAM assessment].
Initial Impression
Based on the above history and examination findings, the patient's altered mental status appears most consistent with [delirium/dementia/psychiatric condition/metabolic encephalopathy/intoxication/withdrawal/structural brain disease/infection].
Plan for Further Evaluation
- Laboratory studies: [CBC/BMP/LFTs/UA/toxicology/cultures/other specific tests].
- Imaging: [Head CT/Brain MRI/Chest X-ray].
- Other studies: [EEG/LP/other specialized testing].
Important Clinical Considerations:
- Always obtain information from both the patient AND a reliable informant 1
- Document fluctuations in mental status, as this is a cardinal feature of delirium 1
- Carefully review all medications, as they are common precipitants of altered mental status 2
- Remember that delirium is a medical emergency with mortality rates twice as high when missed 1
