OBJECTIVES
COVID-19 severity prediction scores need further validation due to evolving COVID-19 illness. We evaluated existing COVID-19 risk prediction scores in Aotearoa New Zealand, including for Māori and Pacific peoples who have been inequitably affected by COVID-19.
METHODS
We conducted a multicenter retrospective cohort study in adults hospitalized with COVID-19 from January to May 2022, including all Māori and Pacific patients, and every second non-Māori, non-Pacific (NMNP) patient to achieve equal analytic power by ethnic grouping. We assessed the accuracy of existing severity scores (4C Mortality, CURB-65, PRIEST, and VACO) to predict death in the hospital or within 28 days.
RESULTS
Of 2319 patients, 582 (25.1%) identified as Māori, 914 (39.4%) as Pacific, and 862 (37.2%) as NMNP. There were 146 (6.3%, 95% confidence interval 5.4-7.4%) deaths, with a predicted probability of death higher than observed mortality for VACO (10.4%), modified PRIEST (15.1%) and 4C mortality (15.5%) scores, but lower for CURB-65 (4.5%). C-statistics (95% CI) of severity scores were: 4C mortality: Māori 0.82 (0.75, 0.88), Pacific 0.87 (0.83, 0.90), NMNP 0.90 (0.86, 0.93); CURB-65: Māori 0.83 (0.69, 0.92), Pacific 0.87 (0.82, 0.91), NMNP 0.86 (0.80, 0.91); modified PRIEST: Māori 0.85 (0.79, 0.90), Pacific 0.81 (0.76, 0.86), NMNP 0.83 (0.78, 0.87); and VACO: Māori 0.79 (0.75, 0.83), Pacific 0.71 (0.58, 0.82), NMNP 0.78 (0.73, 0.83).
CONCLUSIONS
Following re-calibration, existing risk prediction scores accurately predicted mortality.
目的
由于新冠病毒疾病不断演变，新冠病毒疾病严重程度预测评分需要进一步验证。我们评估了新西兰现有的新冠病毒疾病风险预测评分，包括对受新冠病毒疾病影响不平等的毛利人和太平洋岛民。
方法
我们对2022年1月至5月因新冠病毒疾病住院的成年人进行了一项多中心回顾性队列研究，包括所有毛利人和太平洋岛民患者，以及每第二名非毛利、非太平洋岛民（NMNP）患者，以便按种族分组实现同等的分析能力。我们评估了现有严重程度评分（4C死亡率、CURB-65、PRIEST和VACO）预测住院期间或28天内死亡的准确性。
结果
在2319名患者中，582名（25.1%）为毛利人，914名（39.4%）为太平洋岛民，862名（37.2%）为非毛利、非太平洋岛民。共有146例（6.3%，95%置信区间5.4 - 7.4%）死亡，VACO评分（10.4%）、改良PRIEST评分（15.1%）和4C死亡率评分（15.5%）的预测死亡概率高于观察到的死亡率，但CURB-65评分（4.5%）的预测死亡概率较低。严重程度评分的C统计量（95%CI）分别为：4C死亡率：毛利人0.82（0.75，0.88），太平洋岛民0.87（0.83，0.90），非毛利、非太平洋岛民0.90（0.86，0.93）；CURB-65：毛利人0.83（0.69，0.92），太平洋岛民0.87（0.82，0.91），非毛利、非太平洋岛民0.86（0.80，0.91）；改良PRIEST：毛利人0.85（0.79，0.90），太平洋岛民0.81（0.76，0.86），非毛利、非太平洋岛民0.83（0.78，0.87）；VACO：毛利人0.79（0.75，0.83），太平洋岛民0.71（0.58，0.82），非毛利、非太平洋岛民0.78（0.73，0.83）。
结论
重新校准后，现有风险预测评分能准确预测死亡率。
