Chronic obstructive pulmonary disease (COPD), including emphysema and chronic bronchitis, is a progressive condition in which airflow becomes limited, making it difficult to breathe. Chronic lower respiratory diseases, primarily COPD, are the third leading cause of death in the United States, and 5.1% of U.S. adults report a diagnosis of emphysema or chronic bronchitis. Smoking is the primary cause of COPD, and at least 75% of COPD deaths are attributable to smoking in the United States. Information on state-specific prevalence of COPD is sparse, as are data on the use of COPD-related health-care resources. To understand how COPD affects adults in North Carolina and what resources are used by persons with COPD, 2007 and 2009 data from the North Carolina COPD module of the Behavioral Risk Factor Surveillance System (BRFSS) were analyzed. Among 26,227 respondents, 5.7% reported ever having been told by a health professional that they had COPD. Most adults with COPD reported ever having had a diagnostic breathing test (76.4% in 2007 and 82.4% in 2009). Among adults with COPD, 43.0% reported having gone to a physician and 14.9% visited an emergency department (ED) or were admitted to a hospital (2007) for COPD-related symptoms in the previous 12 months. Only 48.1% of persons reported daily use of medications for their COPD (2007). These results indicate that many adults with COPD might not have had adequate diagnostic spirometry, and many who might benefit from daily medications, such as long-acting bronchodilators and inhaled corticosteroids, are not taking them. Continued and expanded surveillance is needed to evaluate the effectiveness of prevention and intervention programs and support efforts to educate the public and physicians about COPD symptoms, diagnosis, and treatment.
慢性阻塞性肺疾病(COPD)包括肺气肿和慢性支气管炎,是一种气流受限逐渐加重的疾病,导致呼吸困难。慢性下呼吸道疾病(主要是 COPD)是美国的第三大死亡原因,5.1%的美国成年人报告患有肺气肿或慢性支气管炎。吸烟是 COPD 的主要病因,在美国,至少 75%的 COPD 死亡归因于吸烟。关于 COPD 的州特异性流行情况的信息很少,关于 COPD 相关医疗保健资源使用的数据也很少。为了了解 COPD 如何影响北卡罗来纳州的成年人以及 COPD 患者使用了哪些资源,分析了 2007 年和 2009 年北卡罗来纳州 COPD 行为风险因素监测系统(BRFSS)模块的数据。在 26227 名受访者中,5.7%的人报告曾被医疗保健专业人员告知患有 COPD。大多数 COPD 患者报告曾进行过诊断性呼吸测试(2007 年为 76.4%,2009 年为 82.4%)。在 COPD 患者中,43.0%的人曾看过医生,14.9%的人因 COPD 相关症状在过去 12 个月内去过急诊室(ED)或住院(2007 年)。只有 48.1%的人报告每天使用药物治疗 COPD(2007 年)。这些结果表明,许多 COPD 患者可能没有接受过充分的诊断性肺活量测定,许多可能受益于长效支气管扩张剂和吸入性皮质类固醇等日常药物治疗的患者并未使用这些药物。需要继续和扩大监测,以评估预防和干预计划的有效性,并支持努力向公众和医生宣传 COPD 症状、诊断和治疗。
