Capacity-building influences on Illinois local health departments

Illinois local health departments (LHDs) were surveyed in 1992 and again in 1994 in order to assess changes in, influences on, and results of practice performance during this two-year period. Illinois LHDs serving both small and large populations were found to have greatly increased the extent to which they carry out practice measures related to public health's core functions. The Assessment Protocol for Excellence in Public Health (APEXPH) and its Illinois adaptation were cited as the most positive influences on practice performance. LHDs viewed the most significant consequences of participation in needs assessment and planning processes as increased understanding of internal strengths and weaknesses and of community health problems. These findings and implications suggest that significant improvements in LHD practice performance can result from widespread implementation of APEXPH and its derivatives.
