Appropriateness criteria were applied to outpatient transthoracic echocardiographic (TTE) studies.
Indications were rated as appropriate, inappropriate, or unclassifiable, considering provider-stated indications, previous TTE studies, symptom changes, and patient-stated indications. Clinically important new or unexpected findings were recorded.
Of 368 TTE studies, 206 (56%) were appropriate, 31 (8%) were inappropriate, and 131 (35%) were unclassifiable. Appropriateness was not correlated with patient or provider demographics. In 288 cases with prior TTE studies, there were 92 (32%) important new findings and 63 (22%) unexpected findings, of which 20% were from inappropriately ordered and 31% from unclassifiable TTE studies. Appropriateness was not associated with new (odds ratio, 1.23; 95% confidence interval, 0.48-3.18) or unexpected (odds ratio, 1.15; 95% confidence interval, 0.38-3.52) findings. Provider type and level of training were not correlated with new or unexpected findings.
Many indications for TTE studies were unclassifiable. A high percentage of inappropriately ordered TTE studies yielded important information. Care must be taken in judging the value of TTE studies solely on the basis of appropriateness criteria.
将适用性标准应用于门诊经胸超声心动图（TTE）检查。
根据医生陈述的指征、既往TTE检查、症状变化以及患者陈述的指征，将指征评定为合适、不合适或无法分类。记录具有临床重要意义的新发现或意外发现。
在368例TTE检查中，206例（56%）是合适的，31例（8%）是不合适的，131例（35%）是无法分类的。适用性与患者或医生的人口统计学特征无关。在288例有既往TTE检查的病例中，有92例（32%）重要新发现和63例（22%）意外发现，其中20%来自检查医嘱开具不当的TTE检查，31%来自无法分类的TTE检查。适用性与新发现（优势比，1.23；95%置信区间，0.48 - 3.18）或意外发现（优势比，1.15；95%置信区间，0.38 - 3.52）无关。医生类型和培训水平与新发现或意外发现无关。
许多TTE检查的指征无法分类。很大比例的检查医嘱开具不当的TTE检查产生了重要信息。仅根据适用性标准判断TTE检查的价值时必须谨慎。
