Abstract

OBJECTIVES

The numbers of nationwide epidemiological surveys about chronic obstructive pulmonary disease (COPD) prevalence and prospective cohort studies for health care utilisation are limited. We investigated COPD-related health care utilisation in adults with obstructive lung disease in the second Korean National Health and Nutritional Survey (KNHANES II) in 2001 using Korean national medical insurance claim data.

METHODS

Among people aged >40 years, obstructive lung disease (OLD) is defined according to Global Initiative for Chronic Obstructive Lung Disease criteria. Data from a total of 1942 subjects were linked with Korean national medical insurance claims data, and we investigated their COPD-related out-patient visits from 2002 to 2005.

RESULTS

Among the 1942 subjects, 256 (13.2%) had airflow obstruction. COPD-related out-patient visits were reported for 8.2% of patients without airway obstruction, 18.1% of those with mild airway obstruction, and 33.9% of those with moderate to very severe airway obstruction. Multivariate analysis revealed that previous COPD diagnosis by a physician (OR 2.54; P = 0.02) and lower socio-economic status (OR 0.45; P = 0.02) were independent predictors of COPD-related out-patient visits in subjects with OLD.

CONCLUSIONS

Of the subjects with airway obstruction, those with poor financial status utilised COPD-related health care services less frequently, and those previously diagnosed as having COPD by a physician utilised the services more frequently.

摘要

目的

关于慢性阻塞性肺疾病（COPD）患病率的全国性流行病学调查和用于医疗保健利用的前瞻性队列研究数量有限。我们利用韩国国家医疗保险索赔数据，调查了 2001 年第二次韩国国家健康和营养调查（KNHANES II）中患有阻塞性肺病的成年人与 COPD 相关的医疗保健利用情况。

方法

在年龄>40 岁的人群中，根据全球慢性阻塞性肺疾病倡议标准定义阻塞性肺疾病（OLD）。共纳入 1942 名受试者的数据与韩国国家医疗保险索赔数据相关联，我们调查了他们在 2002 年至 2005 年期间与 COPD 相关的门诊就诊情况。

结果

在 1942 名受试者中，有 256 名（13.2%）有气流受限。无气道阻塞患者的 COPD 相关门诊就诊率为 8.2%，轻度气道阻塞患者为 18.1%，中度至非常严重气道阻塞患者为 33.9%。多变量分析显示，既往医生诊断为 COPD（OR 2.54；P=0.02）和较低的社会经济地位（OR 0.45；P=0.02）是 OLD 患者 COPD 相关门诊就诊的独立预测因素。
