Implementation of a fast triage score for patients arriving to a low resource hospital in Uganda

Background: The Kitovu Fast Triage (KFT) score predicts imminent mortality from mental status, gait and either respiratory rate or oxygen status. As some non-life-threatening conditions require immediate attention, the South African Triage System (SATS) assigns arbitrary rankings of urgency for specific patient presentations. Aim: Establish the feasibility of determining and then comparing the KFT score and explicitly defined SATS urgency rankings. Methods: A computerized proforma used standardized methods of assessing and measuring mental status and gait, and respiratory rate and collected explicitly defined clinical presentations and SATS urgency rankings on 4,842 patients at the time of their arrival to the hospital. Results: 75 % of patients were awake and able to count the months backwards from December to September. Respiratory rates measured by a computer application had no clustering of values or digit preference; however, oximetry failed in 14 % of patients, making the score based on respiratory rate the most practical in our setting. Determining the SATS acuity ranking and both KFT scores usually took 38 °C. Conclusion: Whilst the KFT score based on respiratory rate could be rapidly determined in all patients, it identified some patients as low acuity who had very urgent SATS rankings. However, most of these patients had non-severe chest pain, which may not be a very urgent presentation in our setting as ischaemic heart disease remains uncommon in sub-Saharan Africa.
