Abstract

Primary objective: To develop and provide initial validation of a measure for accurately determining the need for Constant Visual Observation (CVO) in patients with traumatic brain injury (TBI) admitted to inpatient rehabilitation. Research design: Rating scale development and evaluation through Rasch analysis and assessment of concurrent validity. Methods and procedures: One hundred and thirty-four individuals with moderate–severe TBI were studied in seven inpatient brain rehabilitation units associated with the National Institute for Disability, Independent Living and Rehabilitation Research (NIDILRR) TBI Model System. Participants were rated on the preliminary version of the CVO Needs Assessment scale (CVONA) and, by independent raters, on the Levels of Risk (LoR) and Supervision Rating Scale (SRS) at four time points during inpatient rehabilitation: admission, Days 2–3, Days 5–6 and Days 8–9. Outcomes and results: After pruning misfitting items, the CVONA showed satisfactory internal consistency (Person Reliability = 0.85–0.88) across time points. With reference to the LoR and SRS, low false negative rates (sensitivity > 90%) were associated with moderate-to-high false positive rates (29–56%). Conclusions: The CVONA may be a useful objective metric to complement clinical judgement regarding the need for CVO; however, further prospective study is desirable to further assess its utility in identifying at-risk patients, reducing adverse events and decreasing CVO costs.
