Do Open Fracture Classification Systems Predict Functional Outcomes in a Low-Income Country?: A Prospective Study of...

Area of Science:

• Orthopaedic surgery
• Trauma care
• Public health

Background:

• Open fractures are severe injuries with significant impact on patient quality of life and healthcare costs.
• Existing classification systems aim to predict prognosis and guide treatment for open fractures.
• Assessing the utility of these classifications in diverse settings like Malawi is crucial.

Purpose of the Study:

• To evaluate the agreement between established open fracture classification systems and patient-reported outcomes.
• To determine the correlation between fracture classifications and functional recovery, infection, and amputation rates.
• To assess the relevance of current classifications in a low-income country context.

Main Methods:

• Prospective cohort study of adult patients with open tibia fractures in Malawi.
• Classification of fractures using Gustilo-Anderson, Orthopaedic Trauma Society (OTS), Muller, and Tscherne systems.
• Assessment of patient function (Short Musculoskeletal Assessment Score), infection, and amputation risk over one year.

Main Results:

• The Orthopaedic Trauma Society (OTS) classification showed the strongest correlation with function (0.34) and amputation (0.39) at one year.
• Correlations between most classification systems and patient outcomes were weak to negligible.
• The OTS and Gustilo-Anderson systems demonstrated moderate correlation with fracture-related infection (0.34 and 0.31, respectively).

Conclusions:

• Current open fracture classification systems have limited predictive value for patient outcomes in Malawi.
• Treatment factors and confounders likely play a significant role in outcomes, necessitating adaptable classification systems.
• Development of contextually relevant classifications is needed for low- and middle-income countries to improve open fracture management.
