Cost Analysis of Inpatient Rehabilitation after Spinal Injury: A Retrospective Cohort Analysis

Cureus, 2019 · DOI: 10.7759/cureus.5747 · Published: September 24, 2019

Simple Explanation

This study examines the costs associated with inpatient rehabilitation following a traumatic spine injury. It seeks to understand the factors that influence these costs, using data from a single hospital. The study found that the length of a patient's stay in rehabilitation was the strongest predictor of cost. Injury severity and spinal level of injury were associated with longer rehabilitation stays. The majority of rehabilitation costs were related to facility expenses, such as staff salaries and resources, rather than pharmacy or supplies. The study suggests improving the efficiency of rehabilitation to reduce the length of stay.

Study Duration

2011 to 2017

Participants

190 patients with acute, traumatic spine injury

Evidence Level

Retrospective cohort analysis

Key Findings

1
Facility costs accounted for the vast majority (86.5-90%) of rehabilitation costs after spine injury.
2
Length of rehabilitation stay was the strongest independent predictor of higher rehabilitation costs.
3
Higher injury severity and spinal level were associated with a longer length of stay in rehabilitation, but these factors did not directly correlate with higher costs after adjusting for length of stay.

Research Summary

This retrospective study analyzed the direct costs of inpatient rehabilitation for patients with acute, traumatic spine injuries. The primary objective was to identify factors influencing the cost of rehabilitation. The study found that the length of rehabilitation stay was the most significant predictor of cost. Facility costs, including staff and resources, comprised the largest portion of the total rehabilitation expenses. The authors suggest that improving the efficiency of rehabilitation to reduce the length of stay could be an effective strategy for reducing the overall cost of care for spine injury patients.

Practical Implications

Cost Reduction Strategies

Focus on strategies to reduce the length of stay in inpatient rehabilitation, such as optimizing treatment plans and improving discharge readiness.

Resource Allocation

Recognize that facility costs are the primary driver of rehabilitation expenses and allocate resources accordingly.

Standardized Care

Explore opportunities to standardize treatment protocols to reduce variability in care and potentially lower costs.

Study Limitations

1
Single-center analysis limits generalizability across different health systems.
2
Physician professional fees and indirect costs of care were not included in the analysis.
3
Relatively small cohort size may limit the ability to capture the full clinical spectrum and heterogeneity among patients.
