Nursing Delirium Screening Scale (NuDESC) Tip Sheet

  1. What is the NuDESC?

NuDESC is a screening tool that identifies patients who likely have active delirium. Note: it is a screening tool, not a diagnostic tool. A diagnosis of delirium must be made by a physician.

  1. Why is it important?

Patients who get delirium are more likely to die within a year, experience hospital-acquired complications (falls, pressure ulcers, and functional decline), stay in the hospital longer, and be discharged to a nursing home.There is also evidence that delirium impacts long-term cognitive health. Moreover, delirium is distressing to patients/families and hard on staff.

Literature shows that without regular, formal screening, nurses and physicians miss delirium 50-75% of the time. Delirium signifies acute brain failure. It is, therefore, imperative that it be recognized promptly, so a cause can be identified and corrected.

  1. How do I perform the NuDESC?

Interact with the patient as you would normally over the course of your shift. The beauty of this screening tool is that it does not require you to do anything additional. Just conduct your standard assessment and note the patient’s behavior and communication.

·  Ask open ended questions to determine if your patient can communicate clearly or if s/he seems confused. “Tell me what you understand is the plan for the day.” “What brought you into the hospital?” “How are you feeling?”

·  Assess the patient’s orientation to place, time, and situation.

·  Note the patient’s level of arousal, response time, and ability to engage.

·  Observe the patient’s overall behavior.

  1. When do I do it?

Unlike other daily screens (Schimdt Fall Scale, Braden Skin Scale), NuDESC is intended to be done toward THE END of the shift, as it assesses whether certain behaviors occurred at any point during your time with the patient, as well as the severity of those behaviors. The exception to this is if you suspect your patient is delirious earlier in the shift, please do it then. NuDESC should be repeated if behaviors or level of consciousness becomes more pronounced.

  1. How is it scored?

Toward the end of the shift, (we suggest 4 o’clock when you are documenting vitals) think back on your time with the patient. Each of the 5 items is scored 0-2:

0 – behavior not present during shift

1 – behavior present at some time during the shift, but mild

2 – behavior present at some time during the shift, and pronounced

A score of 2 or greater indicates that the patient screens positive for delirium.

  1. Where do I document it?

NuDESC can be found under Flowsheets à Vital Signs à Nursing Delirium Screening (after the pain assessment)

  1. What do I do if my patient screens positive for delirium?

The FIRST time the patient screens positive for delirium:

·  Notify the primary team and ask them to order the Delirium order set and evaluate and correct potential causes of delirium. The pharmacist will independently review the medication list for deliriogenic meds and write a note in Apex with recommendations to the primary team.

·  Initiate and individualize a Delirium Care Plan. Work with the PCA and rehab staff to execute the interventions.

·  Communicate delirium status and care during all handoffs

  1. What if my patient has cognitive deficits at baseline that cause him/her to repeatedly score 2 or greater?

Patients with baseline cognitive deficits, such as those with dementia, h/o stroke, developmental delay, or seizure disorders, may consistently score 2 or greater, but may not have delirium. These individuals are at very high risk of developing delirium though, so should receive the delirium order set and care plan. The primary team should still evaluate the patient to confirm that s/he is at baseline.

In the example of a patient with dementia who scores a 2 each shift, if this patient were to then score a 4, it is likely that this patient has delirium on top of dementia and the primary team should be notified to evaluate immediately.
