Southern Israel is inhabited by two ethnic groups: predominantly urban Jews and semi-nomad Bedouin Arabs. We evaluated the incidence of hospitalization and differences in clinical characteristics of community-acquired pneumonia (CAP) between these populations.
A hospital-based prospective observational study at Soroka Medical Center, a 1200-bed tertiary care hospital, the single hospital in the region.
All patients admitted with CAP to the internal medicine division during a 5-month winter period.
262 patients were enrolled, of whom 58 (22.1%) were Bedouins. Age-standardized incidence rate for CAP hospitalization among Jews was 68 cases per 100,000 during one winter period, compared to 284 per 100,000 among Bedouins. Bedouin patients were younger than Jewish patients (60.0 +/- 20 vs. 66 +/- 17 years, P = .05). Jews had lower rates of smoking (19.1%, vs. 39.7% P = .001), chronic obstructive pulmonary disease (9.3% vs. 31.0%, P = .001) and diabetes (25.0% vs 41.4%, P = .01). Bedouin patients had a lower rate of pre-hospitalization antibiotic therapy (12.1% vs. 25.5%, P = .03) and influenza vaccination (14.0 vs. 26.8, P = .01). Despite these differences, severity of disease, (measured by Pneumonia Outcome Research Team score), length of hospitalization (median 4 days, P = .38) and 30-day mortality rate (3.4% vs. 8.8%, P = .18) were similar in both populations.
We found a higher incidence of CAP hospitalizations in Bedouin Arabs compared to the Jews. Higher rates of smoking, chronic obstructive pulmonary disease, and lower rates of influenza vaccination most likely contribute to this difference. Despite socioeconomic and clinical differences between the two ethnic groups, no difference was found in the clinical outcomes.
以色列南部居住着两个民族群体：主要是城市犹太人以及半游牧的贝都因阿拉伯人。我们评估了这些人群中社区获得性肺炎（CAP）的住院发生率及临床特征差异。
在索罗卡医疗中心进行的一项基于医院的前瞻性观察研究，该中心是一家拥有1200张床位的三级护理医院，也是该地区唯一的医院。
在冬季的5个月期间，所有因CAP入住内科的患者。
共纳入262例患者，其中58例（22.1%）为贝都因人。一个冬季期间，犹太人中CAP住院的年龄标准化发病率为每10万人68例，而贝都因人中为每10万人284例。贝都因患者比犹太患者年轻（60.0±20岁对66±17岁，P = 0.05）。犹太人吸烟率较低（19.1%对39.7%，P = 0.001）、慢性阻塞性肺疾病发生率较低（9.3%对31.0%，P = 0.001）以及糖尿病发生率较低（25.0%对41.4%，P = 0.01）。贝都因患者院前抗生素治疗率较低（12.1%对25.5%，P = 0.03）以及流感疫苗接种率较低（14.0对26.8，P = 0.01）。尽管存在这些差异，但两组患者的疾病严重程度（通过肺炎结局研究团队评分衡量）、住院时间（中位数4天，P = 0.38）以及30天死亡率（3.4%对8.8%，P = 0.18）相似。
我们发现，与犹太人相比，贝都因阿拉伯人CAP住院的发生率更高。吸烟率、慢性阻塞性肺疾病发生率较高以及流感疫苗接种率较低很可能导致了这种差异。尽管两个民族群体在社会经济和临床方面存在差异，但临床结局并无差异。
