Although psoriasis is seldom life threatening, very few studies have compared differences in health care service use between patients with and without psoriasis.
To investigate differences in health care service use between patients with and without psoriasis.
Patient details and data on their use of health services were retrieved from the Taiwan Longitudinal Health Insurance Database 2000. We included 3649 patients with psoriasis and 3649 without it. Each patient was followed for a 1-year period to estimate their utilization of health care resources. Student t-tests were used to compare differences in health care services use between patients with and without psoriasis.
For dermatology services, patients with psoriasis had significantly more outpatient visits (3·5 vs. 0·9), and higher outpatient and total costs (US$148·00 vs. US$12·20 and US$581·60 vs. US$347·20, respectively) than those without psoriasis. For nondermatology services, patients with psoriasis had more outpatient visits (21·3 vs. 17·6), and higher outpatient and total costs (US$904·60 vs. US$663·50 and US$1335·50 vs. US$998·30, respectively) than those without psoriasis. For overall health care service use, patients with psoriasis had significantly more outpatient visits (24·8 vs. 18·5; P < 0·01) and greater total costs (US$1917·10 vs. US$1345·60; P < 0·01) than those without psoriasis. This indicates that the total cost was about 1·4-fold greater for patients with psoriasis than those without it.
Patients with psoriasis used health care services significantly more often than those without psoriasis.
虽然银屑病很少危及生命，但很少有研究比较过银屑病患者和非银屑病患者在医疗服务使用方面的差异。
调查银屑病患者和非银屑病患者在医疗服务使用方面的差异。
从台湾地区 2000 年纵向健康保险数据库中检索患者详细信息和他们的健康服务使用数据。我们纳入了 3649 例银屑病患者和 3649 例非银屑病患者。对每位患者进行为期 1 年的随访，以评估他们对医疗资源的利用情况。采用学生 t 检验比较银屑病患者和非银屑病患者在医疗服务使用方面的差异。
在皮肤科服务方面，银屑病患者的门诊就诊次数明显更多（3.5 次比 0.9 次），门诊和总费用也更高（148.00 美元比 12.20 美元和 581.60 美元比 347.20 美元）。在非皮肤科服务方面，银屑病患者的门诊就诊次数更多（21.3 次比 17.6 次），门诊和总费用也更高（904.60 美元比 663.50 美元和 1335.50 美元比 998.30 美元）。在整体医疗服务使用方面，银屑病患者的门诊就诊次数明显更多（24.8 次比 18.5 次；P < 0.01），总费用也更高（1917.10 美元比 1345.60 美元；P < 0.01）。这表明银屑病患者的总费用比非银屑病患者高约 1.4 倍。
银屑病患者比非银屑病患者更频繁地使用医疗服务。
