7 Incidence of AP increased between 2000 and 2005 from 13.2 to 14.7 Incidence of AP for males increased from 13.8 to 15.2, for females from 12.7 to 14.2 Mortality for AP fluctuated between 6.9 and 11.7 per million persons/ year and was almost similar for males and females. Incidence and mortality of AP and CP increased markedly with age. CONCLUSION: Incidence of AP steadily increased. Mortality for AP remained fairly stable. Patient burden and health care costs probably will increase because of an ageing BW Ml Spanier et alworld J Gastroenterol 2013 May 28; 19(20):
