• Specifically excludes washing face and hands, and shampooing hair.
• The patient’s ability may change as the patient’s condition improves or declines, as medical restrictions are imposed or lifted, or as the environment is modified. The clinician must consider what the patient is able to do on the day of the assessment. If ability varies over time, choose the response describing the patient’s ability more than 50% of the time period under consideration.


• A combined observation/interview approach with the patient or caregiver is required to determine the most accurate response for this item.
• Ask the patient what type of assistance is needed to wash entire body in tub or shower.
• Observe the patient’s general appearance to determine if the patient has
been able to bathe self as needed.
• Observe patient actually stepping into shower or tub to determine how much assistance the patient needs to perform the activity safely.
• The patient who only performs a sponge bath may be able to bathe in the tub or shower if person or device is available to assist. Evaluate the amount of assistance needed for the patient to be able to safely bathe in tub or shower.
