Spatial and temporal variability of bronchiectasis cases in Silesian voivodeship in 2006–2010

Abstract

Objectives: Reports on an increasing number of hospitalizations in other European countries and the lack of epidemiological data on the prevalence of bronchiectasis in Poland constituted motivation for the authors to investigate temporal changes of the registered incidence and hospitalization due to bronchiectasis in Silesian voivodeship, and to evaluate spatial variability of the disease in the study region. Material and Methods: The study is a descriptive epidemiological project. Temporal and spatial variability of coefficients describing numbers of newly diagnosed cases and first time hospitalizations due to bronchiectasis (code J47 according to International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10)) were evaluated based on the registered data available from the National Health Found (2006)(2007)(2008)(2009)(2010) and the data from MZ/Szp-11 reports (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011). The data concerned adults aged ≥ 19 years, inhabitants of Silesian voivodeship. Maps of incidence or hospitalization rates due to bronchiectasis were constructed by the use of a geographical information system ArcGIS. Results: The obtained results show a stable trend of reported new diseases, whereas the number of first time hospitalizations is increasing. Values of the standardized incidence were 19.9-25.1/100 000 inhabitants, and values of the standardized first-time hospitalization were 1.2-2.9/100 000 inhabitants. The reported rates of bronchiectasis indicate significant spatial differences in epidemiological situation in the study region. Conclusions: The findings showed territorial variability of the incidence and hospitalization of bronchiectasis recorded in Silesian voivodeship. The observed variability might result from regional differences in the availability of specialized medical services.

The economic burden of bronchiectasis – known and unknown: a systematic review

“…One study identified as an abstract in the systematic review has subsequently been published as a full paper [9]. Fifteen studies included > 200 patients; of these, six were conducted in the USA [9–14], three in the UK [15–17], two in Spain [18, 19], and the others in New Zealand [20], Germany [21], Poland [22], and Singapore [23]. All studies involved adults and one included children [20] and a second included individuals of any age.…”

“…[12, 14]. Twenty-two further studies reported on hospitalization rates or length of stay for patients with bronchiectasis; [9, 11, 13–22, 24–33] some of these studies also reported on other aspects of resource use. Eight studies report the costs of managing bronchiectasis and provide evidence for cost drivers in this disease.…”

“…Six studies, conducted over the past 20 years, reported increases in hospitalizations over time (Table 1) [13, 15, 16, 18, 21, 22]. A UK study observed an annual increase in hospitalizations from 2004 ( n = 8611) to 2011 ( n = 15,885) of 9% (relative risk [RR] 1.09, 95% confidence interval [CI] 1.08–1.10, p < 0.0001) [16].…”
