OBJECTIVE

To compare new registrations of recurrences of leprosy cases in primary healthcare units (PHUs) and in specialized units in the State of Mato Grosso.

METHODS

This was a cross-sectional study based on all new registrations (N = 323) of recurrences of leprosy cases within the Notifiable Disease Information System (SINAN) between 2004 and 2006 that were made in the State of Mato Grosso, Central-West Brazil. The cases diagnosed were compared regarding sex, age, clinical-laboratory characteristics and geographical distribution among the municipalities. To compare and calculate the proportions of the variables, the chi-square test at the significance level of 5% was used.

RESULTS

Among the new registrations of recurrences, 20% were confirmed at specialized units and 80% at PHUs. However, most of the diagnoses at PHUs presented negative bacilloscopy findings (c2 = 12.34; p = 0.002). Seventy-one per cent of the cases were among males; the mean age was 43 years. No differences in the percentages of registrations were observed between the healthcare units with regard to clinical form, operational classification or degree of physical incapacity. Out of the total number of municipalities in the state, 64.7% presented recurrences and these accounted for 6 to 20% of all registrations.

CONCLUSIONS

The new registrations of cases of recurrence in Mato Grosso were influenced by the diagnoses made at PHUs, thus suggesting that there is a deficiency within the healthcare services in recognizing cases of recurrence.

目的

比较巴西马托格罗索州基层医疗单位（PHU）和专门单位中新登记的麻风病病例复发情况。

方法

这是一项基于巴西中西部马托格罗索州 2004 年至 2006 年期间通过传染病监测系统（SINAN）登记的所有新麻风病病例复发（N=323）的横断面研究。对诊断出的病例按性别、年龄、临床-实验室特征和市之间的地理分布进行比较。为了比较和计算变量的比例，使用了 5%显著性水平的卡方检验。

结果

在新登记的复发病例中，20%在专门单位确诊，80%在 PHU 确诊。然而，PHU 做出的大多数诊断结果为阴性杆菌镜检（c2=12.34;p=0.002）。71%的病例为男性；平均年龄为 43 岁。在临床形式、操作分类或身体残疾程度方面，医疗单位之间的登记比例没有差异。在全州的总市政单位中，64.7%出现了复发，占所有登记的 6%至 20%。
