The Rehabilitation Complexity Scale--extended version: detection of patients with highly complex needs

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Healthcare Management

Background:

• Assessing rehabilitation complexity is crucial for resource allocation and patient care.
• Existing scales like the Rehabilitation Complexity Scale version 2 (RCS-v2) have limitations in capturing nuanced patient needs.
• The extended Rehabilitation Complexity Scale (RCS-E) was developed to address these limitations.

Purpose of the Study:

• To describe the extended Rehabilitation Complexity Scale (RCS-E) and its factor structure.
• To evaluate the added value of the RCS-E over the RCS-version 2 (RCS-v2) in identifying patients with complex rehabilitation needs.

Main Methods:

• A cohort analysis of 331 patients with complex neurological disabilities undergoing inpatient rehabilitation.
• Prospective collection of routine clinical data, including parallel scoring of RCS-E and RCS-v2 by the multidisciplinary team (MDT).
• Comparison of RCS scores with nursing and therapy dependency scales (NPDS, NPTDA) measuring staff hours per week.

Main Results:

• Very strong correlation between total RCS-E and RCS-v2 scores (ρ = 0.954).
• RCS-E subscales strongly correlated with nursing/care hours (ρ = 0.838) and therapy hours (ρ = 0.697).
• RCS-E demonstrated superior discrimination for complex therapy needs compared to RCS-v2, but not for care/nursing needs.

Conclusions:

• The RCS-E offers an equivalent measure of overall rehabilitation complexity to the RCS-v2.
• The RCS-E provides added value by enhancing the identification of patients with highly complex therapy and equipment requirements.
• The factor structure of RCS-E separates into "Nursing/medical care + Equipment" and "Therapy" dimensions with moderate internal consistency.
