This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.
It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.
If you're a ResearchGate member, you can follow this page to keep up with this author's work.
If you are this author, and you don't want us to display this page anymore, please let us know.

To 1) describe barriers to pneumococcal conjugate vaccine adoption and 2) estimate the value of the vaccine based on pediatricians' responses to willingness-to-pay questions.
In June 2000, we mailed a random sample of pediatricians in Massachusetts a questionnaire about barriers to adoption of the vaccine and willingness to pay for the vaccine and...
Computer-based immunization tracking is a routine part of many pediatric practices; however, data quality is inconsistent and entry often relies on dedicated data entry personnel and is time-consuming, expensive, or difficult. The purpose of this study was to evaluate data quality, nursing satisfaction, and reduction in documentation burden after t...
Underimmunized children are less frequently screened for anemia and elevated lead levels than those who are up-to-date (UTD). However, the association between underimmunization and actual disease (hemoglobin [Hgb] <11 g/dL or blood lead level [PbB] >/=10 microg/dL) has not been reported. The objective of this study was to evaluate the association b...

... Hemoglobin level has been identified as a significant variable in altering BAER latency and conduction times in children with diagnosed iron deficiency anemia. The link between pediatric anemia, as indicated by low HbB levels, and lead (Pb) exposure has been shown in a number of studies [5][6][7]. Pb is a neurotoxin, and Pb exposure may cause a reduction in Hb levels in whole blood and plasma, and may induce anemia [8]. Some studies have reported abnormal BAER in Pb-exposed children and adults [9][10][11], whereas other studies of Pb-exposed children have found no association between Pb levels and BAER parameters [12,13]. ...

... However, the implementation of a mechanism for monitoring BdC must consider contextual health system factors and feasibility. Developing health information management systems is costly and laborious, butalleviate user workload when compared to traditional paper-based systems [27,28]. In this regard, there have been examples of innovative mixed paper and electronic immunisation registries that have shown promise in low-resource settings. ...
... The literature on WTP for childhood vaccinations in high income countries has focused primarily on the value of specific vaccine characteristics, such as reductions in the probability or severity of adverse events, side effects, or pain; reductions in the number of doses or injections; or increases in the number of diseases prevented by combination vaccines. Notable exceptions, namely studies of the WTP for varicella [35], rotavirus [36], and pneumococcal vaccines [48], and for vaccine-effected changes in the probabilities of outcomes or health states, also suggest a positive WTP, on average. The results of our study have important policy implications. ...
