Since 2011, rehabilitation professionals across Cleveland Clinic’s health system have systematically employed 6 Clicks, a pair of electronically administered questionnaires designed to measure the functional status of patients in the acute care hospital. Hospital systems across the United States have embraced the device as a means of rationalizing therapy delivery and improving patient-centered discharge planning.

6 Clicks, conceived and designed at Cleveland Clinic in collaboration with Boston University’s Rehabilitation Outcomes Center, is named for the six questions in two outcomes measurement tools that standardize the assessment of hospitalized patients’ mobility and self-care abilities. To date, Cleveland Clinic staff have logged more than a half million outcomes measurements.

This screening instrument helps determine appropriate patient referrals for physical and/or occupational therapy, aids in discharge planning and improves allocation of treatment resources and personnel. This contributes to a reduction in hospital therapy costs while maintaining quality.

6 Clicks’ queries are derived from the Activity Measure for Post Acute Care (AM-PAC™), a comprehensive set of patient outcome measures developed by Boston University researchers.

6 Clicks’ questions address a patient’s ability to turn in bed, sit, transfer from bed to chair, stand, walk, eat, dress, bathe, perform personal care and use the bathroom. The questions can be answered by a patient or a surrogate and are scored from 1 to 4 by physical or occupational therapists using direct observation of the activity in question or the therapist’s clinical judgment about the patient’s probable ability. The scores are entered into the patient’s electronic medical record and kept as discrete data fields.

Tool nurtures ‘culture of mobility’

Our experience to date with 6 Clicks in more than 577,198 patients has produced a number of insights. The tool has:

• Increased productivity without sacrificing clinical care. We have reduced unnecessary physical therapy visits and as a result have been able to reposition resources, including an increased physical therapy presence in the intensive care unit, enabling earlier intervention.

• Streamlined the patient discharge process through early identification of discharge disposition to long-term acute care, skilled nursing facility, inpatient rehabilitation facility or home.

• Helped educate physicians and nurses about which patients are appropriate referrals for physical and/or occupational therapy.

• Nurtured a “culture of mobility” among the nursing staff by providing guidance on which patients can ambulate without a physical therapist present. Patients with a 6 Clicks score of 18 or above need only minimal help with activities, and the nursing team is tasked with mobilizing them before consulting physical therapy.

Validation studies confirm value

Two studies published in 20141,2 have validated 6 Clicks’ accuracy in predicting patients’ need for therapy in the acute care setting and in predicting the appropriate discharge setting. A third study3 verified the interrater reliability of 6 Clicks’ measures. The research was a collaboration involving Cleveland Clinic, Boston University and the University of Vermont.

We confirmed the validity of 6 Clicks’ basic mobility and daily activities scores in assessing the activity limitations of patients with a wide variety of medical and surgical conditions in an acute care setting. We also found that 6 Clicks scores derived from the initial physical therapy and occupational therapy visits showed fair accuracy in determining patients’ discharge destination. Finally, using pairs of physical and occupational therapists rating the same patients and blinded to each others’ 6 Clicks scores, we found that overall intraclass correlation coefficients were very high, with levels of agreement that varied across the pairs of raters, from large to nearly perfect for physical therapists and from moderate to nearly perfect for occupational therapists.

Taken together, the findings further verify 6 Clicks’ ability to provide valuable guidance in rehabilitation patient care and resource allocation decisions.

In the future, we hope to validate the use of 6 Clicks by nursing personnel and other members of the medical team.
