The uninterrupted initial talking time (UITT) of optometric patients was measured in response to the clinician's opening question: "Do you have any problems with your eyes or your sight?"
UITT was measured surreptitiously by the optometrist. Also noted was whether an eye/sight problem was claimed by the patient and whether or not this was subsequently confirmed by the examination.
Data were collected from 822 adults, mean age 59.1yrs (SD 17.6), range 16.0-92.0yrs. UITT data were positively skewed; median value 28.87s (IQR 19.81-43.03s) and no statistically significant difference between genders (p=0.9). 53% of patients had completed their opening statement by 30s, and 90% after 1min. 75% of these individuals (age range 26-75yrs) had a median UITT 27.82s; younger patients (16-25yrs) spoke for a significantly shorter time (18.39s: p=0.002) and elderly patients (≥76yrs) a significantly longer time (37.27s: p=0.003) than the majority value. Previously unexamined patients, habitual spectacle wearers, and individuals presenting with an eye/sight problem all recorded a significantly longer UITT (p≤0.006) than their peers. The practitioner's opening question had a sensitivity of 0.54/specificity of 0.95, and a positive predictive value (PV) of 0.78/negative PV of 0.87: with a calculated value of κ=0.53, the strength of agreement between subjective claim and objective outcome could be regarded as 'moderate'.
These data suggest that an optometric patient's UITT of <30s is unlikely to prove disruptive to the clinical routine.
针对验光师的开场问题“您的眼睛或视力有任何问题吗?”,测量验光患者的不间断初始谈话时间(UITT)。
验光师暗中测量UITT。同时记录患者是否声称有眼睛/视力问题,以及该问题随后是否经检查得到证实。
收集了822名成年人的数据,平均年龄59.1岁(标准差17.6),年龄范围16.0 - 92.0岁。UITT数据呈正偏态分布;中位数为28.87秒(四分位间距为19.81 - 43.03秒),性别之间无统计学显著差异(p = 0.9)。53%的患者在30秒内完成了开场陈述,1分钟后这一比例为90%。这些人中有75%(年龄范围26 - 75岁)的UITT中位数为27.82秒;年轻患者(16 - 25岁)的谈话时间明显较短(18.39秒:p = 0.002),老年患者(≥76岁)的谈话时间明显较长(37.27秒:p = 0.003),均与多数值不同。以前未经检查的患者、习惯性眼镜佩戴者以及存在眼睛/视力问题的个体的UITT均显著长于(p≤0.006)同龄人。从业者的开场问题敏感性为0.54/特异性为0.95,阳性预测值(PV)为0.78/阴性预测值为0.87:计算得出κ值为0.53,主观声称与客观结果之间的一致性强度可视为“中等”。
这些数据表明,验光患者的UITT<30秒不太可能对临床流程造成干扰。
