Abstract
PURPOSE OF REVIEW To summarize evidence-based strategies for improving pediatric immunization rates including physician behaviors, clinic and public health processes, community-based and parent-focused interventions, and legal and policy approaches RECENT FINDINGS: Studies continue to show the effectiveness of audit and feedback, provider reminders, standing orders, and reminder/recall to increase immunization rates. Provider communication strategies may improve immunization rates including use of a presumptive approach and motivational interviewing. Centralized reminder/recall (using a state Immunization Information System) is more effective and cost-effective compared to a practice-based approach. Recent work shows the success of text messages for reminder/recall for vaccination. Web-based interventions, including informational vaccine websites with interactive social media components, have shown effectiveness at increasing uptake of pediatric and maternal immunizations. Vaccination requirements for school attendance continue to be effective policy interventions for increasing pediatric and adolescent vaccination rates. Allowance for and ease of obtaining exemptions to vaccine requirements are associated with increased exemption rates. SUMMARY Strategies to increase vaccination rates include interventions that directly impact physician behavior, clinic and public health processes, patient behaviors, and policy. Combining multiple strategies to work across different settings and addressing different barriers may offer the best approach to optimize immunization coverage.

Chang LV. THE EFFECT OF STATE INSURANCE MANDATES ON INFANT IMMUNIZATION RATES. HEALTH ECONOMICS 2016; 25:372-386. [PMID: 25773053 DOI: 10.1002/hec.3153] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/17/2013] [Revised: 10/31/2014] [Accepted: 12/30/2014] [Indexed: 06/04/2023]
Abstract
While US infant immunization rates have been increasing in the last 20 years, the cost of fully immunizing a child with all recommended vaccines has almost tripled. This is partly not only due to new additions in the list of recommended vaccines but also due to the use of new, safer, but more expensive technologies in vaccine production and distribution. In recent years, many states have mandated that recommended childhood vaccines be covered by private health insurance companies. Currently, there are 33 states with such a mandate. In this paper, I examine whether the introduction of mandates on private insurers affected immunization rates. Using state and time variation, I find that mandates increased the immunization rate for three vaccines--the diphtheria-tetanus-pertussis, polio, and measles-mumps-rubella vaccines--by about 1.8 percentage points. These results may provide a lower bound for the expected effect of the Affordable Care Act, which mandates coverage of childhood vaccines for all private insurers in the USA. I also find evidence that the mandates shifted a significant portion of vaccinations from publicly funded sources to private ones, with a decline in public health clinic visits and an increase in vaccinations at hospitals and doctor's offices.

Abstract
Strategies to increase adolescent immunization rates have been suggested, but little is documented about which strategies clinicians actually use or would consider. In spring 2010, we surveyed primary care physicians from 2 practice-based research networks (PBRNs): Greater Rochester PBRN (GR-PBRN) and national pediatric COntinuity Research NETwork (CORNET). Network clinicians received mailed or online surveys (response rate 76%, n=148). The GR-PBRN patient population (51% suburban, 33% rural, and 16% urban) differed from that served by CORNET (85% urban). For nonseasonal vaccines recommended for adolescents, many GR-PBRN and CORNET practices reported using nurse prompts to providers at preventive visits (61% and 52%, respectively), physician education (53% and 53%), and scheduled vaccine-only visits (91% and 82%). Strategies not used that clinicians frequently indicated they would consider included patient reminder/recall and prompts to providers via nurses or electronic health records. As preventive visits and immunization recommendations grow more complex, using technology to support immunization delivery to adolescents might be effective.

Abstract
Annual epidemics of seasonal influenza occur during autumn and winter in temperate regions and have imposed substantial public health and economic burdens. At the global level, these epidemics cause about 3-5 million severe cases of illness and about 0.25-0.5 million deaths each year. Although annual vaccination is the most effective way to prevent the disease and its severe outcomes, influenza vaccination coverage rates have been at suboptimal levels in many countries. For instance, the coverage rates among the elderly in 20 developed nations in 2008 ranged from 21% to 78% (median 65%). In the U.S., influenza vaccination levels among elderly population appeared to reach a "plateau" of about 70% after the late 1990s, and levels among child populations have remained at less than 50%. In addition, disparities in the coverage rates across subpopulations within a country present another important public health issue. New approaches are needed for countries striving both to improve their overall coverage rates and to eliminate disparities. This review article aims to describe a broad conceptual framework of vaccination, and to illustrate four potential determinants of influenza vaccination based on empirical analyses of U.S. nationally representative populations. These determinants include the ongoing influenza epidemic level, mass media reporting on influenza-related topics, reimbursement rate for providers to administer influenza vaccination, and vaccine supply. It additionally proposes specific policy implications, derived from these empirical analyses, to improve the influenza vaccination coverage rate and associated disparities in the U.S., which could be generalizable to other countries.

Abstract
OBJECTIVE We examined associations between influenza vaccination rates and Medicaid reimbursement rates for vaccine administration among poor children who were eligible for Medicaid (<100% of the federal poverty level in all states). METHODS We analyzed 3 consecutive National Immunization Surveys (NISs) to assess influenza vaccination rates among nationally representative children 6 to 23 months of age during the 2005-2006 (unweighted N = 12 885), 2006-2007 (unweighted N = 9238), and 2007-2008 (unweighted N = 11 785) influenza seasons (weighted N = 3.3-4.0 million per season). We categorized children into 3 income levels (poor, near-poor, or nonpoor). We performed analyses with full influenza vaccination as the dependent variable and state Medicaid reimbursement rates (continuous covariate ranging from $2 to $17.86 per vaccination) and terms with income levels as key covariates. RESULTS In total, 21.0%, 21.3%, and 28.9% of all US children and 11.7%, 11.6%, and 18.8% of poor children were fully vaccinated in the 2006, 2007, and 2008 NISs, respectively. Multivariate analyses of all 3 seasons found positive significant (all P < .05) associations between state-level Medicaid reimbursement and influenza vaccination rates among poor children. A $10 increase, from $8 per influenza vaccination (the US average) to $18 (the highest state reimbursement), in the Medicaid reimbursement rate was associated with 6.0-, 9.2-, and 6.4-percentage point increases in full vaccination rates among poor children in the 2006, 2007, and 2008 NIS analyses, respectively. CONCLUSION Medicaid reimbursement rates are strongly associated with influenza vaccination rates.

Abstract
PURPOSE This study was conducted to document current immunization practices by family physicians. METHODS In 2008 the American Academy of Family Physicians (AAFP) conducted a survey among a random sample of 2,000 of its members who reported spending 80% or more of their time in direct patient care. The survey consisted of questions regarding the demographics of the practice, vaccines that are provided at the physicians' clinical site, whether the practice refers patients elsewhere for vaccines, and participation in the Vaccines for Children (VFC) program. RESULTS The response rate was 38.5%, 31.8% after non-office-based respondents were deleted. A high proportion of respondents (80% or more) reported providing most routinely recommended child, adolescent, and adult vaccines at their practice sites. The exceptions were rotavirus vaccine for children and herpes zoster vaccine for adults., A significant proportion, however, reported referring elsewhere for some vaccines (44.1% for children and adolescent vaccines and 53.5% for adult vaccines), with the most frequent referral location being a public health department. A higher proportion of solo and 2-physician practices than larger practices reported referring patients. A lack of adequate payment was listed as the reason for referring patients elsewhere for vaccines by one-half of those who refer patients. One-half of responders do not participate in the VFC program. CONCLUSIONS Provision of recommended vaccines by most family physicians remains an important service. Smaller practices have more difficulty offering a full array of vaccine products, and lack of adequate payment contributes to referring patients outside the medical home. The reasons behind the lack of participation in the VFC program deserve further study.

Abstract
OBJECTIVES The goals were to estimate nationally representative pediatric practices' costs of providing influenza vaccination during the 2006-2007 season and to simulate the costs pediatric practices might incur when implementing universal influenza vaccination for US children aged 6 months to 18 years. METHODS We surveyed a stratified, random sample of New York State pediatric practices (N = 91) to obtain information from physicians and office managers about all practice resources associated with provision of influenza vaccination. We estimated vaccination costs for 2 practice sizes (small and large) and 3 geographic areas (urban, suburban, and rural). We adjusted these data to obtain national estimates of the total practice cost (in 2006 dollars) for providing 1 influenza vaccination to children aged 6 months to 18 years. RESULTS Among all respondents, the median total cost per vaccination was $28.62 (interquartile range: $18.67-45.28). The median component costs were as follows: clinical personnel labor costs, $2.01; nonclinical personnel labor costs, $7.96; all other (overhead) costs, $10.43. Vaccine purchase costs averaged $8.22. Smaller practices and urban practices had higher costs than larger or suburban practices. With the assumption of vaccine administration reimbursement for all Vaccines for Children (VFC)-eligible children at the current Medicaid median of $8.40, the financial loss across all US pediatric practices through delivery of VFC vaccines would be $98 million if one third of children received influenza vaccine. CONCLUSION The total cost for pediatric practices to provide influenza vaccination is high, varies according to practice characteristics, and exceeds the average VFC reimbursement.

Abstract
Recent increases in the number and costs of vaccines routinely recommended for children and adolescents have raised concerns about the ability of the current vaccine financing and delivery systems to maintain access to recommended vaccines without financial barriers. Here we review the current state of US financing for vaccine delivery to children and adolescents and identify challenges that should be addressed to ensure future access to routinely recommended vaccines without financial barriers. Challenges were considered from the perspectives of vaccine providers; state and local governments; insurers, employers, and other health care purchasers; vaccine manufacturers; and consumers.

Abstract
OBJECTIVE The goal was to describe variable costs to providers of delivering childhood immunizations. METHODS We documented variable costs (costs that vary with the amount of services rendered), including time spent by pediatric staff members and physicians on immunization-related activities, as well as supply costs and medical waste disposal costs. Ten private pediatric practices in the Denver, Colorado, metropolitan area participated in the study. Among the 7 practices that provided us with payment data, 8 health plans were mentioned by > or = 2 practices. There were 37 different agreements between the health plans and practices for vaccine administration payments. RESULTS The total documented variable cost per injection (excluding vaccine cost) averaged $11.51, calculated from the following categories: nursing time, $1.71; billing services, $2.67; nonroutine services, $1.64; registry use, $0.96; physician time, $4.05; supplies, $0.36; medical waste disposal, $0.12. Nonroutine activities primarily included performing vaccine inventory and ordering, providing vaccination records to requesters, and answering parent telephone questions about vaccinations. With the use of a simulation model to compensate for the small number of participating practices, the calculated total variable cost per injection was $11.83. When 2 vaccines were administered, we compared the sum of the 2 payments with the sum of the 2 variable costs ($23.02). More than one third of the payment agreements (13 of 37 agreements) paid the practices less than the combined variable costs for 2 immunizations. CONCLUSION This study shows that the variable costs of vaccine administration exceeded reimbursement from some insurers and health plans.

Abstract
The Vaccines for Children (VFC) program supplies health-care providers with federally purchased vaccines at no cost for administration to eligible children. Evaluation of vaccine accountability activities ensures appropriate and timely vaccinations are delivered. Program grantees in 50 states, Washington, five large U.S. metropolitan cities, and five U.S. territories and possessions completed a Web-based survey between December 2002 and January 2003 focused on current vaccine accountability operational systems. Most grantees required providers to complete profiles describing the vaccination needs and demographics of their practices. More than half requested providers use benchmarking data, doses-administered reports, and/or claims or encounter data to determine their VFC program-eligible population size; however, > 65% did not have written procedures for investigating and reconciling discrepancies between estimated vaccine needs and actual vaccine-use data. Most grantees had written standard policies requiring providers to report vaccine loss and wastage routinely and to explain why they occurred. Ninety percent of grantees did not have procedures to check providers for fraud and abuse sanctions, and 52% did not have written procedures to address complaints of vaccine fraud and abuse. These results suggested specific areas in which the Centers for Disease Control and Prevention should work with grantees to improve vaccine accountability practices. As a result, enhancements to the VFC program are being implemented to address these areas and their impact evaluated for their effectiveness in ensuring the continued success of the VFC program in protecting the nation's most vulnerable children and adolescents.

Abstract
BACKGROUND Medical homes are health care settings that offer continuous, comprehensive, accessible primary care; these settings generally involve pediatric and family physician practices or community health centers but can also involve gynecologists or internists. OBJECTIVES In this article, we review available evidence on the role of the medical home in optimizing adolescent immunization delivery, particularly with respect to health care utilization patterns and barriers to vaccinations in medical homes, and solutions. METHODS We conducted a systematic review of the existing immunization and adolescent literature and used a Delphi process to solicit opinions from content experts across the United States. RESULTS Most adolescents across the United States do have a medical home, and many pay a health care visit to their medical home within any given year. Barriers exist in regards to the receipt of adolescent immunizations, and they are related to the adolescent/family, health care provider, and health care system. Although few studies have evaluated adolescent vaccination delivery, many strategies recommended for childhood or adult vaccinations should be effective for adolescent vaccination delivery as well. These strategies include education of health care providers and adolescents/parents; having appropriate health insurance coverage; tracking and reminder/recall of adolescents who need vaccination; practice-level interventions to ensure that needed vaccinations are provided to eligible adolescents at the time of any health care visit; practice-level audits to measure vaccination coverage; and linkages across health care sites to exchange information about needed vaccinations. Medical homes should perform a quality improvement project to improve their delivery of adolescent vaccinations. Because many adolescents use a variety of health care sites, it is critical to effectively transfer vaccination information across health care settings to identify adolescents who are eligible for vaccinations and to encourage receipt of comprehensive preventive. CONCLUSIONS Medical homes are integral to both the delivery of adolescent immunizations and comprehensive adolescent preventive health care. Many strategies recommended for childhood and adult vaccinations should work for adolescent vaccinations and should be evaluated and implemented if they are successful. By incorporating evidence-based strategies and coordinating effectively with other health care sites used by adolescents, medical homes will be the pivotal settings for the delivery of adolescent vaccinations.

Abstract
OBJECTIVE Our goal was to examine the association of continuous care in the medical home and health insurance on up-to-date vaccination coverage by using data from the National Survey of Children's Health and the National Immunization Survey. METHODS Interviews were conducted with 5400 parents of 19- to 35-month-old children to collect data on demographics and medically-verified vaccinations. Health insurance coverage was categorized as always, intermittently, or uninsured for the previous 12 months. Insurance types were private, public, or uninsured. Having a personal doctor or nurse and receiving preventive health care in either the past 12 or 24 months constituted continuous primary care in the medical home. Children were up-to-date if they received all vaccinations by 19 to 35 months of age (>or=4 doses of diphtheria and tetanus toxoids and pertussis vaccine, >or=3 doses of poliovirus vaccine, >or=1 dose of any measles-containing vaccine, >or=3 doses of Haemophilus influenzae type b vaccine, and >or=3 doses of hepatitis B vaccine). RESULTS Bivariate analyses revealed children who were always insured had significantly higher vaccination coverage (83%) than those with lapses or uninsured during the past 12 months (75% and 71%, respectively). Those with continuous primary care in the medical home had significantly higher coverage than those who did not (83% vs 75%, respectively). In multivariate analysis, the same pattern of association was observed for insurance status and medical home, but the only statistically significant association was for children of never-married mothers who had significantly lower coverage (74%) compared with children of married mothers (84%). CONCLUSIONS Among children with the same insurance status and continuity of care in the medical home, children of single mothers were less likely to be up-to-date than children of married mothers. Interventions assisting single mothers to obtain preventive care for their children should be a priority.

Abstract
BACKGROUND Pneumococcal conjugate vaccine immunization recommendations were rapidly implemented by primary care providers. Before the recommendations, concern was expressed that adding pneumococcal conjugate vaccine might result in delays in other vaccinations or preventive services. OBJECTIVES The study objectives were to measure whether incorporation of pneumococcal conjugate vaccine by primary care providers delayed other vaccinations or added primary health care visits. DESIGN AND METHODS In 2 counties surrounding Rochester and Nashville, we reviewed a representative sample of primary care charts for children born before and after licensure of pneumococcal conjugate vaccine. Receipt of vaccinations and health care visits were compared for the 2 age-matched cohorts. RESULTS We reviewed 1459 records from Rochester and 1857 records from Nashville. The pre-pneumococcal conjugate vaccine and post-pneumococcal conjugate vaccine cohorts had similar demographic characteristics. The median age for receipt of any vaccination was not older for the postvaccine cohort than for the prevaccine cohort in either community. The percentage of children up-to-date for vaccinations by 18 months for postvaccine versus prevaccine cohorts was similar in Rochester (72% in each cohort) and in Nashville (58% postvaccine and 65% prevaccine). The number of well-child care visits or other health care visits during the first 18 months of life was not statistically different between the 2 cohorts. CONCLUSIONS Implementation of pneumococcal conjugate vaccine was not associated with delays in other childhood vaccinations or more primary care visits.

Abstract
Background The Vaccines for Children (VFC) Program is a major vaccine entitlement program with limited long-term evaluation. The objectives of this study are to evaluate the effect of VFC on physician reported referral of children to public health clinics and on doses administered in the public sector. Methods Minnesota and Pennsylvania primary care physicians (n = 164), completed surveys before (e.g., 1993) and after (2003) VFC, rating their likelihood on a scale of 0 (very unlikely) to 10 (very likely) of referring a child to the health department for immunization. Results The percentage of respondents likely to refer was 60% for an uninsured child, 14% for a child with Medicaid, and 3% for a child with insurance that pays for immunization. Half (55%) of the physicians who did not participate in VFC were likely to refer a Medicaid-insured child, as compared with 6% of those who participated (P < 0.001). Physician likelihood to refer an uninsured child for vaccination, measured on a scale of 0 to 10 where 10 is very likely, decreased by a mean difference of 1.9 (P < 0.001) from pre- to post-VFC. The likelihood to refer a Medicaid-insured child decreased by a mean of 1.2 (P = 0.001). Conclusion Reported out-referral to public clinics decreased over time. In light of increasing immunizations rates, this suggests that more vaccines were being administered in private provider offices.

Abstract
BACKGROUND Immunization rates for children and adults are rising, but coverage levels have not reached optimal goals. As a result of low immunization rates, vaccine-preventable diseases still occur. In an era of increasing complexity of immunization schedules, rising expectations about the performance of primary care and large demands on primary care physicians, it is important to understand and promote interventions that work in primary care settings to increase immunization coverage. A common theme across immunization programs in all nations involves the challenge of determining the denominator of eligible recipients (e.g. all children who should receive the measles vaccine) and identifying the best strategy to ensure high vaccination rates. Strategies have focused on patient-oriented interventions (e.g., patient reminders), provider interventions and system interventions. One intervention strategy involves patient reminder and recall systems. OBJECTIVES To assess the effectiveness of patient reminder and recall systems in improving immunization rates and compare the effects of various types of reminders in different settings or patient populations. SEARCH STRATEGY A systematic search was performed for the initial review using MEDLINE (1966-1998) and four other bibliographic databases: EMBASE, PsychINFO, Sociological Abstracts, and CAB Abstracts. Authors also performed a search of The Effective Practice and Organisation of Care (EPOC) register in April 2001 to update the review. Two authors reviewed the lists of titles and abstracts and used the inclusion criteria to mark potentially relevant articles for full review. The reference lists of all relevant articles and reviews were back searched for additional studies. Publications of abstracts, proceedings from scientific meetings and files of study collaborators were also searched for references. In December 2004 the EPOC register was searched to identify relevant articles to update the review. STUDY DESIGN Randomized controlled trials (RCT), controlled before and after studies (CBA) and interrupted time series (ITS) studies written in English. TYPES OF PARTICIPANTS Health care personnel who deliver immunizations and children (birth to 18 years) or adults (18 years and up) who receive immunizations in any setting. TYPES OF INTERVENTIONS Any intervention that falls within the EPOC scope (See Group Details) and that includes patient reminder or recall systems, or both, in at least one arm of the study. TYPES OF OUTCOME MEASURES Immunization rates or the proportion of the target population up-to-date on recommended immunizations. Outcomes were acceptable for either individual vaccinations (e.g. influenza vaccination) or standard combinations of recommended vaccinations (e.g. all recommended vaccinations by a specific date or age). DATA COLLECTION Each study was read independently by two reviewers. Disagreements between reviewers were resolved by a formal reconciliation process to achieve consensus. ANALYSIS Results are presented for individual studies as relative rates for randomized controlled trials and as absolute changes in percentage points for controlled before and after studies. Pooled results for RCTs only were presented using the random effects model. MAIN RESULTS Five new studies were added for this update. Increases in immunization rates due to reminders were in the range of 1 to 20 percentage points. Reminders were effective for childhood vaccinations (OR = 1.45, 95% CI =1.28, 1.66), childhood influenza vaccinations (OR = 2.87, 95% CI = 1.65, 4.98), adult pneumococcus, tetanus, and Hepatitis B (OR = 2.19, 95% CI = 1.21, 3.99), and adult influenza vaccinations (OR = 1.66, 95% CI = 1.31, 2.09). All types of reminders were effective (postcards, letters, telephone or autodialer calls), with telephone being the most effective but most costly. AUTHORS' CONCLUSIONS Patient reminder and recall systems in primary care settings are effective in improving immunization rates within developed countries.

Abstract
BACKGROUND The Vaccines for Children (VFC) program is designed to reduce the cost of vaccines for vulnerable children, including Medicaid-eligible children, American Indian/Alaska Native children, uninsured children, and underinsured children whose health insurance does not cover the cost of vaccinations. A desired consequence of the program is to promote comprehensive continuous medical care within a medical home for these children. OBJECTIVES To explore how having a medical home is associated with vaccination coverage among children eligible for the program. PARTICIPANTS A total of 24514 children 19 to 35 months of age sampled by the National Immunization Survey. DESIGN VFC eligibility was evaluated for 24514 children 19 to 35 months of age who were sampled by the National Immunization Survey. Children were considered to have a medical home if they had a doctor, nurse, or physician's assistant who provided them with ongoing routine care, including well-child care, preventive care, and sick care, according to their parents. Sampled children were determined to be 4:3:1:3:3 up-to-date (UTD) if their vaccination providers reported administering >or=4 doses of diphtheria-tetanus toxoids-acellular pertussis vaccine, >or=3 doses of polio vaccine, >or=1 dose of measles-mumps-rubella vaccine, >or=3 doses of Haemophilus influenzae type b vaccine, and >or=3 doses of hepatitis B vaccine. RESULTS Nationally, 44.9% of all children were VFC eligible and 93.0% of the VFC-eligible children received all vaccine doses at a provider enrolled in the VFC program. Compared with children who were not VFC eligible, VFC-eligible children were less likely to be UTD (70.8% vs 77.7%) and less likely to have a medical home (82.1% vs 95.0%). However, among VFC-eligible children, children who had a medical home were significantly more likely to be UTD, compared with children who did not have a medical home (72.3% vs 63.5%). Also, among VFC-eligible children who had a medical home, children who used their medical home consistently to receive all of their vaccination doses were significantly more likely to be UTD, compared with children who did not receive all of their doses from their medical home (75.3% vs 65.7%). Finally, the 4:3:1:3:3 vaccination coverage rate among VFC-eligible children who received all of their vaccination doses from their medical home was not significantly different from that among non-VFC-eligible children, after controlling for significant differences in sociodemographic factors between these groups (adjusted difference: 2.8%; 95% confidence interval: -0.1% to 5.7%). CONCLUSIONS Although the vaccination coverage rate among VFC-eligible children who had a medical home and received all vaccine doses from their medical home was essentially equivalent to that of non-VFC-eligible children, substantial percentages of VFC-eligible children either did not have a medical home or did not use their medical home to receive all of their recommended vaccinations. The vaccination coverage rate among these children was significantly lower. This suggests that there may be opportunities to increase vaccination coverage by removing barriers that prevent the adoption and consistent use of a medical home among these children.

Abstract
BACKGROUND Adolescent immunization is a growing field, with many new vaccines in development and new or expanded immunization recommendations on the horizon. METHODS Characteristics of adolescents and their health care are discussed, focusing specifically on the challenges of incorporating a potential recommendation to replace tetanus-diphtheria toxoid with tetanus-diphtheria-acellular pertussis vaccine during early or middle adolescence as part of routine preventive care. Using the framework created by the Centers for Disease Control and Prevention's Task Force on Community Preventive Services, three overlapping levels at which there are opportunities for vaccine intervention are reviewed: (1) health care systems (enhancing access to vaccination services); (2) health care providers (provider-based interventions); and (3) patients and families ("increasing community demand"). RESULTS There are several barriers to vaccine implementation that make achieving high immunization coverage rates among adolescents a challenge. Promising interventions for improving vaccination rates at the health care system level include reducing out-of-pocket costs, expanding access to immunizations, and implementing vaccination programs in schools. Provider-based interventions for improving vaccination rates include regular assessments of immunization rate with feedback to all office personnel, provider reminders, and standing orders. Client recall and reminders, education, and requirements for school entry can assist in "increasing community demand" for vaccinations in that they motivate parents and adolescents to follow through with immunizations. CONCLUSIONS Adolescents are unique from other populations. Previously studied interventions need to be tested in this age group as immunization becomes a more salient issue in adolescent health care.

Abstract
BACKGROUND There is concern that commercial health insurance reimbursement levels for immunizations and well-child visits may not be meeting the delivery and practice overhead costs within some areas of the country. There is also concern that insufficient physician reimbursement levels may negatively affect the quality of children's health care. OBJECTIVE We examined the relationships between commercial health insurance reimbursement levels to physicians for pediatric services and rates of immunization and well visits for children and adolescents. DESIGN Quality of care was measured by examining state-level immunization and well-visit rates for 2002, which were obtained from the National Committee for Quality Assurance, Health Plan Employer Data and Information Set (HEDIS). Reimbursement data were obtained from the American Academy of Pediatrics Medical Cost Model. Variations in the child and adolescent HEDIS measures were examined as a function of physician reimbursement levels for pediatric services across states. HEDIS data were available for a total of 32 states. Partial correlations controlled for pediatrician concentration, as collected from the US Bureau of the Census and the American Medical Association Physician Masterfile data. RESULTS Compliance with HEDIS immunization rates for all recommended vaccines was 60% for children and 24% for adolescents. By excluding the varicella vaccine, these rates increased to 70% for children and 44% for adolescents. Adherence rates for well visits were also higher for infants (60%) and children (59%) than for adolescents (34%). Physician reimbursement levels for pediatric services varied from 16.88 dollars per member per month to 32.06 dollars per member per month across states. Statistically significant positive correlations for reimbursement levels were found for 8 of the 16 HEDIS measures examined. Correlations with reimbursement levels were found for childhood immunizations (r = 0.42), infant well visits (r = 0.44), childhood well visits (r = 0.46), and adolescent well visits (r = 0.42). Reimbursement levels were especially strongly related to the rates of adolescent varicella vaccination (r = 0.53). When partial correlations were examined to control for pediatrician concentration, the correlations were reduced by 0.09 on average, suggesting that pediatrician supply may serve as an intermediary of the reimbursement relationship. CONCLUSIONS Immunization and well-visit rates for infants, children, and adolescents were positively linked with physician reimbursement rates for those services. Although methodologic limitations suggest caution when interpreting these findings, more attention should be given to physician reimbursement levels as a possible predictor of immunization and well-visit rates as measures of quality of care and to the importance of reimbursement levels for pediatrician recruitment.

Abstract
OBJECTIVE To describe costs to providers of delivering childhood immunizations. METHODS We collected variable costs--costs that vary with the amount of services rendered--including cost of practitioner and staff time and supplies, using a cost accounting method, from 12 practices (4 pediatric practices, 4 family practices, and 4 public health agencies) in rural and urban areas in Colorado. For private practices, we estimated fixed costs--costs that do not vary with the amount of services, eg, rent and insurance). We also collected reimbursement information for vaccinations for private practices. RESULTS Variable costs per shot (excluding vaccine cost) were 8.15 dollars for pediatric practices, 5.79 dollars for family practices, and 5.41 dollars for public health agencies. Total costs per shot, including fixed costs, were 10.67 dollars for pediatric practices and 7.57 dollars for family practices. Average reimbursement for pediatricians and private family practices was 8.27 dollars and 6.68 dollars, respectively. For pediatric practices, average variable costs were barely exceeded by average reimbursement, and reimbursement was 22% less than average total costs. This contrasts with an earlier study of the rural practices investigated here, in which there was a comfortable margin between reimbursement and variable costs. CONCLUSION The decline in the ratio of reimbursement to cost for private practices, particularly for pediatric practices, suggests that referral to public agencies by private providers for vaccinations may increase and that if vaccinations are not as frequently provided in the child's medical home, then the currently high childhood immunization rates may be in jeopardy.

Abstract
To evaluate the economic impact of the current 2-dose measles-mumps-rubella (MMR) vaccination program in the United States, a decision tree-based analysis was conducted with population-based vaccination coverage and disease incidence data. All costs were estimated for a hypothetical US birth cohort of 3803295 infants born in 2001. The 2-dose MMR vaccination program was cost-saving from both the direct cost and societal perspectives compared with the absence of MMR vaccination, with net savings (net present value) from the direct cost and societal perspectives of US dollars 3.5 billion and US dollars 7.6 billion, respectively. The direct and societal benefit-cost ratios for the MMR vaccination program were 14.2 and 26.0. Analysis of the incremental benefit-cost of the second dose showed that direct and societal benefit-cost ratios were 0.31 and 0.49, respectively. Varying the proportion of vaccines purchased and administered in the public versus the private sector had little effect on the results. From both perspectives under even the most conservative assumptions, the national 2-dose MMR vaccination program is highly cost-beneficial and results in substantial cost savings.

Abstract
Children in the United States receive immunizations through both private and public sectors. The federal government has supported childhood immunization since 1963 through the Vaccination Assistance Act (Section 317 of the Public Health Service Act). Since 1994, the Vaccines for Children (VFC) program has provided additional support for childhood vaccines. In 2002, 41% of childhood vaccines were purchased through VFC, 11% through Section 317, 5% through state and/or local governments, and 43% through the private sector. The recent introduction of more-expensive vaccines, such as pneumococcal conjugate vaccine, has highlighted weaknesses in the current system. Adult immunization is primarily performed in the private sector. Until 1981, there was no federal support for adult immunization. Since 1981, Medicare has reimbursed the cost of pneumococcal vaccine for its beneficiaries; influenza vaccine was added in 1993. This paper summarizes the history of financing immunizations in the United States and discusses some current problems and proposed solutions.

Abstract
BACKGROUND Barriers to adult immunizations persist as current rates for pneumococcal polysaccharide vaccine (PPV) receipt among eligible adults remain below national goals. This study investigated potential barriers to patients receiving the PPV, including predisposing, enabling, environmental and reinforcing factors among physicians from a variety of practice and geographic settings. METHODS Participants were 60 primary care physicians from inner-city, rural, suburban, and Veterans Affairs practices, which included adults aged 65 years and older. Elderly patients able to complete a telephone interview were randomly selected from each physician's practice. RESULTS Self-reported PPV vaccination status was significantly related to physician report of routinely providing PPV to their patients and to the practice providing immunization clinics or other immunization promotion programs. Physicians who were highly unlikely to refer uninsured adults to health departments for immunizations had a significantly higher percentage of patients reporting receipt of PPV (P = .03). CONCLUSIONS Enabling and environmental factors related to physicians, such as economic and insurance issues, were significant barriers to PPV vaccination. Vaccination rates might be improved through efforts that reduce likelihood of referral for immunizations and office systems that support immunization, such as patient and provider reminders and express vaccination clinics.

Abstract
OBJECTIVE In 2000, heptavalent pneumococcal conjugate vaccine (PCV7) was recommended for children younger than 2 years, but its high cost relative to other universally recommended childhood immunizations and variability in insurance coverage for the vaccine raised concerns. We investigated the influence of PCV7 cost and insurance coverage on physician recommendation of PCV7 to their patients and administration of PCV7 in their practices. METHODS We conducted a mail survey from April to July 2001 of a random sample of 833 pediatricians and 788 family physicians in 24 states with different vaccine financing strategies (Vaccines for Children [VFC]-only; enhanced VFC; universal purchase). Physicians specified the proportion of children in their practice with insurance coverage for PCV7, where they recommend administering PCV7, and whether they have concerns about the cost of PCV7. RESULTS The response rate was 60%. Overall, 87% of physicians recommend PCV7 for children younger than 2 years (99% pediatricians; 68% family physicians). Among physicians who recommend PCV7, 98% said that they would administer the vaccine in their own practices for children whose insurance covers the vaccine. However, only 56% of physicians who recommend PCV7 reported that all children in their practices had insurance coverage for the vaccine, whereas 24% of physicians reported 86% to 99% of children with coverage and 20% reported <or=85% of children with coverage. Among physicians in the last group with the lowest PCV7 insurance coverage rates in their practices, only 44% said that they would administer the vaccine in their own practices to children without PCV7 coverage, compared with 62% of physicians who provide care to children with higher rates of PCV7 coverage. Physicians in states with VFC-only vaccine financing strategies for PCV7 are less likely to administer PCV7 in their own practices to children without coverage than physicians in states with enhanced VFC and universal purchase strategies (48% vs 64% vs 74%). Almost one third of physicians who recommend PCV7 are concerned about the cost of PCV7; those with cost concerns are more likely to recommend that children without insurance coverage for PCV7 receive the vaccine at a public health clinic rather than in their own practices (45% vs 29%). Physicians with cost concerns are also more likely to say that they now screen children for insurance coverage more than for previously recommended vaccines (52% vs 21% for physicians without cost concerns). CONCLUSIONS Nationwide, physician adoption of PCV7 recommendations is high, but where physicians recommend that PCV7 be administered differs significantly by children's variable insurance coverage for the vaccine and by state vaccine financing strategies. Physicians' concerns about the cost of PCV7 may foreshadow their responses to future children's vaccines that may be even more expensive.

Abstract
OBJECTIVES To determine physician success at designing catch-up regimens for children delayed in immunizations and physician knowledge regarding contraindications to immunization. METHODS A self-administered survey was completed by pediatricians, general practitioners, and family practitioners in Cook County, Illinois. Surveys included 6 open-ended vignettes describing hypothetical children delayed in immunization for whom participants were asked to design catch-up regimens. Bivariate and multivariate logistic regression were used to determine predictors of correct response. The surveys also inquired about management of scenarios that might be perceived as contraindications to immunize with the Haemophilus influenzae type b or measles-mumps-rubella vaccines. RESULTS The mean score of correct responses was 1.83 of a possible 6.0. Almost one third of respondents answered all 6 vignettes incorrectly. The proportion of incorrect responses was high for all 6 vignettes (39%-86%), but higher for questions that addressed the immunization of children older than 12 months. Errors in vaccine administration were most commonly attributed to omitted vaccines, with varicella-zoster vaccine and pneumococcal conjugate vaccine omitted most frequently. Pediatricians were >4 times more likely to answer correctly than were family practitioners. Participants in the Vaccines for Children (VFC) program were more than twice as likely to answer correctly than were non-VFC providers. Knowledge of contraindications was inconsistent, particularly for measles-mumps-rubella vaccine. CONCLUSIONS Childhood vaccine providers have substantial knowledge deficits of recommended immunization schedules and vaccine contraindications that may contribute to missed opportunities to immunize. Pediatricians and participants in the VFC program were more successful at designing catch-up regimens for children with immunization delay.

Abstract
OBJECTIVES Characterize the Vaccines for Children (VFC) programs in Minnesota and Pennsylvania, assess providers' satisfaction with each state's program, and examine changes in doses administered in the public sector since implementation of the VFC. METHODS Primary care providers participating in the VFC in Minnesota and Pennsylvania were surveyed. Doses administered were based on data from the National Immunization Survey. Outcome measures included satisfaction, ease of use of VFC, doses of immunizations administered through public health departments, and overall immunization coverage for the two states. RESULTS Most participating providers in each state (80% to 94%) reported overall satisfaction with the VFC. Pennsylvania physicians were less satisfied with quarterly ordering of immunizations than were Minnesota providers with monthly ordering (56% vs 80%, p<0.05). The most common recommendation was to reduce paperwork. Doses administered in the public sector declined in Minnesota from approximately 146,000 in 1994 to 65,400 in 1999, and in Pennsylvania from approximately 250,000 to 79,300 during the same period. CONCLUSIONS The VFC appears to increase the numbers of poor and uninsured children who receive necessary childhood immunizations within their medical homes. Providers are generally satisfied with the program.

Abstract
OBJECTIVE Started in late 1994, the Vaccines for Children (VFC) program is a major entitlement program that provides states with free vaccines for disadvantaged children. Some evaluation studies have been conducted, but they do not include individually matched pre-post comparisons of physician responses. This project studied the effect of the VFC on the physician likelihood of referring children to public vaccine clinics for immunizations. DESIGN In 1999, trained personnel conducted a survey of a cohort of physicians who previously participated in surveys on barriers to childhood vaccination conducted before VFC implementation. Responses were matched, and pre- versus post-VFC comparisons were made. SETTING AND PARTICIPANTS Minnesota and Pennsylvania primary care physicians selected by stratified random sampling and initially studied in 1990 to 1991 and 1993, respectively. MAIN OUTCOME MEASURES Likelihood of referral of a child to a public vaccine clinic. RESULTS On a scale of 0 to 10, physician likelihood of referring an uninsured child decreased by a mean of 1.9 (95% confidence interval: 1.2-2.5) from pre- to post-VFC. Two fifths (45%) of physicians reported that the VFC decreased the number of referrals from their practice to public vaccine clinics and 50% gave intermediate responses. Among physicians who participate in VFC, only 9% were likely to refer a Medicaid-insured child in contrast to 44% of those not participating. CONCLUSIONS Physicians' reported referral and likelihood of referring Medicaid-insured and uninsured children has decreased because of VFC in Minnesota and Pennsylvania.vaccination/economics, vaccination/legislation and jurisprudence, immunization programs/economics, immunization programs/utilization, vaccines/economics, Medicaid/economics, national health programs United States, child health services.

Abstract
BACKGROUND How many physicians are needed in the United States and how they should be allocated geographically and among specialties has been the subject of intense debate, a debate that has often focused more on costs to third-party payers and government than on benefits to health. Child health is a central aspect of public health, and immunization is one of its most cost-effective and easily measured interventions. OBJECTIVE To examine the association of immunization rates and delivery characteristics with the distribution of child health physicians in the United States in 1997. DESIGN Cross-sectional ecological study, using the state as the unit of analysis, immunization rates and delivery characteristics (from the National Immunization Survey) as the main outcome measures, concentration of the principal physician specialties providing routine care to children (pediatric, family, and general physicians from the American Medical Association Masterfile) as the main risk factor, while controlling for demographic and economic factors (from the Bureau of the Census and other sources). RESULTS Of the 96 689 physicians providing routine care to children, 37% were pediatric, 49% family, and 14% general physicians. Higher rates of vaccination, private sector vaccination, and increased numbers of public and private vaccination sites were all associated with the concentration of pediatricians but not of family or general physicians. The distribution of pediatricians was strongly associated with the distribution of residency positions. CONCLUSIONS Pediatrician distribution is a strong correlate to immunization rates and delivery characteristics. Opportunities to affect pediatrician distribution may exist with allocation of residency positions.
