Background: Universal access to information for health professionals is a prerequisite for meeting thernMillennium development Goals and achieving Health for All. In developing countries, a large proportionrnof the population, including health professionals, has no or only poor access to HI outlets. The problem isrnmuch serious in those working in Primary Health Care (PHC) settings. This study was conducted tornassess level of access to HI resources by health workers working in public health centers in Addis Ababa.rnObjective: To assess HI access among health professionals working in HIV/AIDS related programmesrnand family health clinics at primary public health institution in Addis Ababa.rnMethods: A cross-sectional quantitative and qualitative (in-depth interview) study designs werernemployed. Health professionals working on VCT/ART and family health at Addis Ababa public healthrncentres were study subjects. Self administered questionnaire were used on 169 subjects to assess the levelrnof access to HI resourcesrnResults: The majority (94.8%) of respondents reported that they seek information when a need arises.rnSeventy one(46.7%) of the respondents reported being computer literate and only 33.8% of thernrespondents reported to have access to the internet from any source and internet access, have shown nornstatistically significant association(p>0.05) with the variables . Access to different HI resources to thernhealth workers is limited; local or international journals (12%), library service (25.5%) and trainingrn(58.8%). The over all HI access were observed by six types of resources where half (50.6%) of thernrespondents were found to have satisfactory access to HI resources . working program were observed tornhave association with access level. Those working in HIV/AIDS unit were found to have a 2.5 timesrnbetter likely hood of getting satisfactory HI sources as compared to those working in family health clinicrnCOR=2.66, with 95% CI(1.35, 5.23) and AOR= 2.5(1.2, 5.2).rnConclusion: Most study subjects have limited access to many of the HI resources; internet, journals,rnlibrary service with printed materials, and training. Therefore, more efforts has to be made to ensure arnsustainable HI access points to help those working in the ever changing health contexts in order tornmaximize evidence based patient quality care.
