The Impact of Residency and Urbanicity on Haemophilus influenzae Type b and Pneumococcal Immunization in Shanghai Children: A Retrospective Cohort Study

Background Haemophilus influenzae type b (Hib) vaccine and pneumococcal conjugate vaccine (PCV) are relatively expensive, newly introduced vaccines in China. This study evaluates the impact of residency and urbanicity on Hib vaccine and PCV coverage for children aged 2 to 7 years living in Shanghai, China, in August 2012. Methods In this exploratory cohort study, a sample of children aged 2 to 7 years, all of whom were eligible to have received the complete series of Hib vaccine and PCV, was obtained from the Shanghai Immunization Program Information System. Three measures of vaccination coverage for Hib vaccine and PCV were examined: dose 1 coverage, series completion, and timeliness of dose 1 vaccination. Multivariable binomial regression was used to estimate the difference in vaccination coverage between locals and the floating population. Results Dose 1 coverage was 50.9% for Hib vaccine and 11.4% for PCV for the 28,141 abstracted pediatric records. For both vaccines, dose 1 coverage was higher in locals than in the floating population. The disparity in coverage between locals and the floating population was greater in suburban areas than urban areas. Of all children who received dose 1, 79.7% completed the Hib vaccine series, and 91.3% completed the PCV series. Timely dose 1 coverage was 8.2% for Hib vaccine and 0.5% for PCV. Conclusion Low vaccination coverage and extremely low levels of timely dose 1 vaccination indicate that current vaccination efforts are inadequate to reduce the burden of Hib and pneumococcal disease among Chinese children, especially infants. Government funding of the Hib vaccine and PCV through the Expanded Program on Immunization would increase uptake and could also ensure that improvement in the timeliness of administration and series completion is targeted for all demographic groups.

Human rabies in Tianjin, China

BACKGROUND Human rabies has recently re-emerged as a significant public health threat in Tianjin, China. METHODS Using surveillance data compiled by the Tianjin Centers for Disease Control and Prevention, we describe 60 cases of human rabies reported from 2005 to 2011 in the municipality of Tianjin, China. RESULTS All 60 cases of human rabies resulted in death. Cases were primarily male (80%), middle aged (mean 40.6 years), and exposed to rabies in a rural setting (82%). Most exposures were associated with dog bites (93%) and no animal had a history of rabies vaccination; no cases were laboratory confirmed. Fifteen percent of patients sought medical attention for their wound, and none received a complete regimen of WHO-recommended post-exposure prophylaxis (PEP). CONCLUSIONS These findings suggest the need for Chinas public health authority to improve animal rabies surveillance and control strategies through laboratory case confirmation, more rapid response to potential exposures with provision of appropriate PEP, and education to the public and to health care providers on identifying and reducing rabies risk.

Trends in Michigan Early Adolescent Immunization: 2006–2008

OBJECTIVES We have described vaccine coverage of Michigan young adolescents immunized with tetanus, diphtheria, and pertussis; meningococcal conjugate; and human papillomavirus vaccines during 2006-2008. METHODS We obtained data from the Michigan Care Improvement Registry, a state-based immunization information system that included more than 57 million vaccination records. We examined 3 overlapping cohorts of 11- and 12-year-old children (n > 350 000 in each) to assess temporal trends in vaccination coverage, characteristics of those immunized, funding sources, and vaccination sites. RESULTS Vaccine uptake increased during 2006 through 2008, peaking in the summer months. More than half of children receiving more than 1 vaccine received the vaccines simultaneously. Older age, receipt of Medicaid, and prior completion of early childhood immunizations were associated with greater odds of vaccination. CONCLUSIONS Vaccine coverage among Michigan young adolescents is increasing but continues to be relatively low. Coverage of 11- and 12-year-old children may improve with efforts to encourage vaccination at all health care visits, an increase in public funding in support of adolescent vaccination, and continued monitoring of adolescent vaccination levels through school-based assessments.

Did H1N1 influenza prevention messages reach the vulnerable population along the mississippi gulf coast

OBJECTIVE To identify the primary sources of information utilized by a vulnerable population during the 2009 influenza pandemic and examine disease prevention behaviors related to reports of local H1N1 influenza transmission. DESIGN Cross-sectional study. SETTING Between May 2009 and December 2009, face-to-face interviews were conducted in towns located in 3 Mississippi counties along the Gulf Coast. PARTICIPANTS Two hundred sixteen residents of the Mississippi Gulf Coast were interviewed. MAIN OUTCOME MEASURES Analysis of the interview results described awareness of the influenza outbreak/pandemic and sources of information about the situation. Chi-square tests were used to examine differences in reported disease-preventive behaviors taken by Mississippi Gulf Coast residents before and after H1N1 influenza transmission was confirmed locally. RESULTS Most subjects were aware of H1N1 influenza at the time of interview (n = 212; 98%). Television (n = 145; 69%), newspaper (n = 40; 19%), and the Internet (n = 19; 9%) were the most common sources of information regarding H1N1 influenza. Hand hygiene (n = 85; 41%) was the most reported preventive measure adopted by study subjects and increased following the confirmation of the first H1N1 influenza cases in Harrison County (χ= 4.46, p= 0.04). CONCLUSIONS The Centers for Disease Control and Preventions emphasis on providing health information about H1N1 primarily through the Internet may not have been effective in reaching the public. Provision of health messages through various mediums, especially television, may better inform the public of disease-related prevention messages during a developing influenza pandemic.

Mapping student response team activities to public health competencies: are we adequately preparing the next generation of public health practitioners?

This article compares activities of the University of Michigan School of Public Health Public Health Action Support Team (PHAST) to the Centers for Disease Control and Prevention/Council of State and Territorial Epidemiologists Applied Epidemiology Competencies (AECs) to determine the utility of using the competencies to assess extracurricular student training. We mapped the activities from eight PHAST trips occurring from 2006 to 2009 to the 34 AECs for Tier 1 epidemiologists by examining project activities to determine how closely they aligned with the AECs. PHAST trips provided students with opportunities to address 65% of the AECs; 29% of the AECs were addressed by all eight trips. The domains of AECs most often addressed by PHAST trips were leadership and systems thinking, cultural competency, and community dimensions of practice. Mapping PHAST trips to the AECs was useful for all public health students, not just epidemiologists in training.

Epidemiology Competencies and Preventive Medicine Residencies: Do They Mix and Map?

Objectives. This article maps the program requirements of the University of Michigan preventive medicine residency (PMR) to the newly established Centers for Disease Control and Prevention/Council of State and Territorial Epidemiologists Competencies for Applied Epidemiologists in Governmental Public Health Agencies (AECs) to determine the feasibility and utility of using these competencies to assess the training of physician epidemiologists. Methods. The academic and practicum requirements of the PMR are mapped against the 38 AECs for Tier 2, or mid-level epidemiologists. The process of mapping was done by reviewing academic course syllabi/content and practicum tasks to determine how closely they aligned with the AECs. This process allowed us to identify competencies that are relative training strengths and weaknesses of the residency. Results. Overall, the current program requirements of the PMR generally satisfy the AECs, although one competency was not met in either the academic or practicum year, and another was only met in a single, required academic course. The areas in which AECs were fulfilled by many activities in the residency were in domain 1 (assessment and analysis) and domain 2 (basic public health sciences). The areas in which competencies were met by few activities were primarily in domain 6 (financial and operational planning and management) and domain 7 (leadership and systems thinking). Conclusions. We found that the process of mapping an academically rigorous epidemiology training program (the PMR) to the AEC was feasible and useful. It permitted us to identify training strengths and gaps in our program and consider modifications that will strengthen the level of competency of our physician graduates.

Influenza vaccination of adults with and without high-risk health conditions in China

Background The World Health Organization recommends the elderly and persons with certain chronic diseases to receive an annual influenza vaccine and to be prioritized for immunization against pandemic influenza, because they are at greater risk for health complications. This paper aims to compare influenza vaccination coverage between adults in China with and without high-risk health conditions. Methods Data were from the cross-sectional China General Social Survey, 2010. Adults were interviewed about their health, including whether they had been vaccinated against either seasonal or pandemic influenza within the past year. A multivariable logistic regression model estimated the adjusted odds of any influenza vaccination in high-risk groups compared with low-risk groups. Results Only 10.5% (372/3592) of Chinese adults were vaccinated against influenza. In a multivariable regression model, there was no significant difference in influenza vaccine uptake between those with and without high-risk health conditions. However, healthcare attitudes and behaviours were significantly associated with vaccine uptake. Conclusions Influenza vaccination coverage is extremely low in Chinese adults who are elderly and have chronic diseases. These two groups are at greatest risk for influenza-related morbidity and mortality and should be targets of programmes to increase positive attitudes towards vaccination and decrease barriers to uptake.

Promoting practice in public health academia: Assessing impact on student education

This article reviews the activities of an office of public health practice in a school of public health (SPH) and assesses their impact on masters of public health student training and education. The University of Michigan SPH established a Practice Office in 2005 to develop programs in community-based public health, workforce development, student training, and practice-based research. Student training objectives included increasing practice activity offerings and participation rates, ensuring participant satisfaction with activities, and raising the number of students seeking public health practice employment. According to student survey results from the 2007-2008 and 2008-2009 academic years, the Practice Office achieved mixed success in meeting objectives. Approximately 50% of students participated in at least 1 activity, nearly 50% of students reported that the activities impacted their decision to pursue a practice career, and approximately 75% of students reported moderate to extensive public health practice experience on graduation, compared with 30% at the beginning of their degree program, although this change was not significantly different for those who had participated in Practice Office activities. Initiation of a systematic process to evaluate the impact of practice-based activities early in program development is recommended for all Practice Offices.

An evaluation of immunization services, using the reaching every district criteria, in two districts of Gujarat, India

BackgroundImmunizations are considered the most successful and cost-effective public health interventions employed today. While immunization coverage in India has improved dramatically in the last decade, areas of very low coverage persist. The University of Michigan School of Public Health and the Indian Institute of Public Health Gandhinagar collaborated to document strengths and weaknesses of immunization service delivery in two districts in India.MethodsThis report describes a qualitative assessment of clinic level immunization service delivery in ten primary health centers (PHCs) located in two districts of Gujarat, India. Assessment criteria were derived from the Reaching Every District (RED) strategy that is intended to provide a framework for delivering childhood immunizations. Staff from the PHCs were interviewed in April 2013.ResultsInterviews revealed several barriers to immunization service delivery including: 1) Vaccine and supply stockouts; 2) Hard to reach communities; 3) Unreliable Internet access; 4) Cold chain equipment malfunctions; 5) Inconsistently maintained and utilized immunization records and registries.ConclusionsImmunization service delivery is a complex process that can encounter barriers at many stages. A RED-based evaluation of the vaccine delivery system in Gujarat, India identified several points where the system was performing sub-optimally and possible solutions to successfully address these challenges.
