Background: The goal of this pilot study was to correlate missed opportunities to immunize young children with providers’ psychosocial characteristics and self-reported immunization practices.Methods: In a population of children aged 0 to 36 months, missed opportunities to immunize were established for a sample of 28 providers, who also responded to a valid and reliable instrument measuring the aforementioned variables.Results: Missed opportunities were significantly lower among providers with higher vested interest (r=−0.45, p=0.02) and tended to be lower among providers with more positive attitudes toward having all children properly immunized at every healthcare visit (r=−0.33, p =0.09). Neither knowledge nor perceived barriers correlated significantly with missed opportunities. Providers missed opportunities to immunize in over half of the visits studied (mean, 0.58), yet all of them reported always immunizing at preventive and follow-up visits, almost all (96.3%) at chronic illness visits, and a majority (78.6%) at acute care visits. As a result, none of the self-reported immunization practices was significantly correlated with missed opportunities.Conclusions: Missed opportunities appear to be best predicted by motivational psychosocial factors and not by knowledge or perceived barriers. Self-reported immunization practices do not correspond to actual immunization behavior. [Copyright &y& Elsevier]

This was a prospective randomized cohort study to assess the effectiveness of an educational immunization intervention with pregnant Latinas on timely initiation of infant immunization. Study participants were recruited from two community clinics in north San Diego County. A total of three hundred and fifty-two Latinas in the third trimester of pregnancy were recruited and randomly assigned to intervention or control groups. Participants received either a culturally and linguistically appropriate session on infant immunization (intervention) or a session on prevention of Sudden Infant Death Syndrome (control). The main outcome measures were pre-post immunization knowledge change and infant immunization status at 92 days. Immunization knowledge increased significantly in the intervention group [p < .0001, 95%CI (1.76, 2.47)]. No difference was found between groups in immunization series initiation: 95 percent of the children in the intervention group were up-to-date by 92 days from birth, and 93 percent of the control group was up-to-date at 92 days. The lack of significant association between receiving immunization education and infant immunization series initiation suggests that parent education may be necessary but not sufficient for timely immunization, particularly in clinics with effective well-child programs. Given the significant increase in immunization knowledge, the broader and perhaps more important implication is that language- and culturally specific infant health education messages in the prenatal period may have a positive long-term impact on the child's health and promote well-child care overall. Future studies should assess the role of prenatal well-child education in the context of clinics with low immunization levels.

Demands to optimize productivity and quality require a patient scheduling system that can balance patient demand and clinic resources. The consequences of unscheduled and late patient arrivals on operational efficiencies have been documented. Less understood is the impact of unscheduled and late arrivals on the quality of service each receives. This article examines the impact of unscheduled and late patient arrivals on operational, clinical and administrative outcomes that affect quality of care of children potentially eligible for immunizations. An unexpected finding was the generally better and faster levels of service for late arrivals.
