Filter by:Pertussis (also known as whooping cough) is a highly contagious, vaccine-preventable respiratory tract disease, caused by the bacteria Bordetella pertussis. It can affect people of all ages, however young unimmunised or partially immunised infants are the most vulnerable group with the highest rates of complications and death. Recent surveillance data and an increase in the number of pertussis outbreaks being reported nationally, indicate an increase in the incidence of pertussis disease in South Africa.To date there is no data on the effect of vaccinating HIV-infected pregnant women with pertussis-containing vaccines, although there is no reason to think that vaccinating these women would be harmful for them or their foetus. The knowledge gaps on the immunogenicity, safety and VE of pertussis vaccination of HIV-infected pregnant women should be addressed. Adacel which is a registered and licensed vaccine manufactured by Sanofi Pasteur, will be tested in this study.
Dissemination research examines the processes and factors that lead to widespread use of evidence-based interventions. There are several theories on how to best minimize the perceived and actual burdens on practitioners associated with implementing evidence-based medicine. For instance, the pay for performance model attempts to improve physician compliance with quality guidelines by providing financial incentives. Recent studies suggest pay for performance is effective in improving practitioner performance, but it is unclear whether the gains are sustainable once incentives are stopped. Another approach to promoting best practices is the Model for Improvement whose main method is to employ Plan-Do-Study-Act (PDSA) cycles of small changes Although this approach has been successful within individual institutions, there is minimal evidence of its effect when employed simultaneously in multiple autonomous institutions. There is also little evidence of the sustainability of outcomes after intervention activities end. The specific aims of the proposed study are to examine the effect of quality improvement dissemination models on the immunization coverage of children ages 3 to 18 months old. The investigators propose to: 1. Determine the effect on immunization compliance of two different models of dissemination which will provide physicians 12 months of quality improvement (QI) activity support for implementing CDC immunization best practices. Hypothesis 1a: Study participants receiving the QI technical support intervention (QITS) will have more improvement in immunization rates from baseline to immediately after support ends than participants receiving the pay for performance intervention (P4P). Hypothesis 1b: Study participants receiving QITS will increase immunization coverage for their practices over baseline. Hypothesis 1c: Study participants receiving P4P will increase immunization coverage for their practices over baseline.
