PENNA, Maria Lucia Fernandes et al. The influence of increased access to basic healthcare on the trends in Hansen's disease detection rate in Brazil from 1980 to 2006. Rev. Soc. Bras. Med. Trop. [online]. 2008, vol.41, suppl.2, pp. 6-10. ISSN 1678-9849. http://dx.doi.org/10.1590/S0037-86822008000700003.
Brazilian Hansen's disease detection rate rose during the 80s and 90s of the 20th century. The Brazilian health system reform happened during the same period. Detection rate is a function of the real incidence of cases and the diagnostic agility of the health system. Coverage of BCG immunization in infants was used as a proxy variable for primary healthcare coverage. A log-normal regression model of detection rate as a function of BCG coverage, time and time square was adjusted to data. The detection rate presents an upward trend throughout the period and with a downturn beginning in 2003. The model showed a statistically significant positive regression coefficient for BCG coverage, suggesting that detection rate behavior reflects the improvement of access to health care. The detection rate began a trend towards decline in 2003, indicating a new phase of Hansen's disease control.
