title: [Cataract surgery rate and its impacting factors in Jiangsu Province in 2012].
abstract: OBJECTIVE
  To survey the cataract surgery rate (CSR) according to the report data and its influencing factors of Jiangsu Province in 2012 so as to further improve CSR in China.
  
  
  METHODS
  Through government websites in 2012, gross domestic product (GDP) and GDP per capital of 13 cities in Jiangsu Province and 7 counties of Nantong City reported to the Ministry of Health in China were collected to calculate CSR. The relationship between GDP and CSR of Jiangsu Province and Nantong City were analyzed with Spearman's rank correlation, and the differences in the proportion of cataract surgery between government and private hospitals were analyzed by Chi-square test.
  
  
  RESULTS
  CSR in Jiangsu Province in 2012 was 939 cases per million population per year. Nantong City had the highest CSR (1362 cases per million population per year) and Suqian City the lowest (129 cases per million population per year). The GDP of 13 cities in Jiangsu Province had a positive correlation with CSR (spearman r = 0.59, P = 0.03), but there was no significant correlation with GDP per capital (spearman r = 0.50, P = 0.08). No significant correlation existed between GDP, GDP per capital and CSR of 7 counties of Nantong City (spearman r = -0.04, P = 0.94; spearman r = -0.29, P = 0.53). The proportion of private hospitals of Nantong was 33.3% and surgery cases were 4557 (45.9%). The CSR of Rugao County in 2012 was 3317 cases per million population per year.
  
  
  CONCLUSIONS
  Socioeconomic level may be related with CSR. Providing village cataract screening services and lowering surgical costs help to boost CSR in China.
