Impact of vaccine financing on vaccinations delivered by health department clinics

Timing of Clinical Billing Reimbursement for a Local Health Department

OBJECTIVES

A major responsibility of a local health department (LHD) is to assure public health service availability throughout its jurisdiction. Many LHDs face expanded service needs and declining budgets, making billing for services an increasingly important strategy for sustaining public health service provision. Yet, little practice-based data exist to guide practitioners on what to expect financially, especially regarding timing of reimbursement receipt. This study provides results from one LHD on the lag from service delivery to reimbursement receipt.

METHODS

Reimbursement records for all transactions at Maricopa County Department of Public Health immunization clinics from January 2013 through June 2014 were compiled and analyzed to determine the duration between service and reimbursement. Outcomes included daily and cumulative revenues received. Time to reimbursement for Medicaid and private payers was also compared.

RESULTS

Reimbursement for immunization services was received a median of 68 days after service. Payments were sometimes taken back by payers through credit transactions that occurred a median of 333 days from service. No differences in time to reimbursement between Medicaid and private payers were found.

CONCLUSIONS

Billing represents an important financial opportunity for LHDs to continue to sustainably assure population health. Yet, the lag from service provision to reimbursement may complicate budgeting, especially in initial years of new billing activities. Special consideration may be necessary to establish flexibility in the budget-setting processes for services with clinical billing revenues, because funds for services delivered in one budget period may not be received in the same period. LHDs may also benefit from exploring strategies used by other delivery organizations to streamline billing processes.

Comparative performance of public and private sector delivery of BCG vaccination: evidence from Sub-Saharan Africa

BACKGROUND

The private sector is an important source of health care in the developing world. However, there is limited evidence on how private providers compare to public providers, particularly for preventive services such as immunizations. We used data from Sub-Saharan Africa (SSA) to assess public-private differences in Bacillus Calmette-Guérin (BCG) vaccine delivery.

METHODS AND FINDINGS

We used demographic and health surveys from 102,629 children aged 0-59 months from 29 countries across SSA to measure differences in BCG status for children born at private versus public health facilities (BCG is recommended at birth). We used a probit model to estimate public-private differences in BCG delivery, while controlling for key confounders. Next, we estimated how differences in BCG status evolved over time for children born at private versus public facilities. Finally, we estimated heterogeneity in public-private differences based on wealth and rural-urban residency. We found that children born at a private facility were 7.1 percentage points less likely to receive BCG vaccine in the same month as birth than children born at a public facility (95% CI 6.3-8.0; p<0.001). Most of this difference was driven by for-profit private providers (as opposed to NGOs) where the BCG provision rate was 10.0 percentage points less than public providers (95% CI 9.0-11.2; p<0.001) compared to only 2.4 percentage points for NGOs (95% CI 1.0-3. 8; p<0.01). Moreover, children born at private for-profit facilities remained less likely to be vaccinated up to 59 months after birth. Finally, public-private differences were more pronounced for poorer children and children in rural areas.

CONCLUSIONS

The for-profit private sector performed substantially worse than the public sector in providing BCG vaccine to newborns, resulting in a longer duration of vulnerability to tuberculosis. This disparity was greater for poorer children and children in rural areas.

Estimation of immunization providers' activities cost, medication cost, and immunization dose errors cost in Iraq

The immunization status of children is improved by interventions that increase community demand for compulsory and non-compulsory vaccines, one of the most important interventions related to immunization providers. The aim of this study is to evaluate the activities of immunization providers in terms of activities time and cost, to calculate the immunization doses cost, and to determine the immunization dose errors cost. Time-motion and cost analysis study design was used. Five public health clinics in Mosul-Iraq participated in the study. Fifty (50) vaccine doses were required to estimate activities time and cost. Micro-costing method was used; time and cost data were collected for each immunization-related activity performed by the clinic staff. A stopwatch was used to measure the duration of activity interactions between the parents and clinic staff. The immunization service cost was calculated by multiplying the average salary/min by activity time per minute. 528 immunization cards of Iraqi children were scanned to determine the number and the cost of immunization doses errors (extraimmunization doses and invalid doses). The average time for child registration was 6.7 min per each immunization dose, and the physician spent more than 10 min per dose. Nurses needed more than 5 min to complete child vaccination. The total cost of immunization activities was 1.67 US$ per each immunization dose. Measles vaccine (fifth dose) has a lower price (0.42 US$) than all other immunization doses. The cost of a total of 288 invalid doses was 744.55 US$ and the cost of a total of 195 extra immunization doses was 503.85 US$. The time spent on physicians' activities was longer than that spent on registrars' and nurses' activities. Physician total cost was higher than registrar cost and nurse cost. The total immunization cost will increase by about 13.3% owing to dose errors.

Pediatrician attitudes concerning school-located vaccination clinics for seasonal influenza

OBJECTIVE

Vaccinating all children aged 6 months to 18 years every year has potentially large ramifications for office-based primary care pediatricians. We determined the degree to which pediatricians support routine annual influenza vaccination outside the medical home, especially in school-located mass influenza vaccination clinics.

METHODS

Internet-based survey sent in May and June 2009 to all 623 currently practicing primary care general pediatricians who were members of the Maryland Chapter of the American Academy of Pediatrics.

RESULTS

Of those surveyed, 193 (31%) responded. Approximately 67% reported they vaccinated more than half the children in their practice with at least one dose in the 2008-2009 influenza season, and about half anticipated that, in their office, they would not attain ≥75% coverage of all patients older than 5 months of age. Approximately 27% of respondents predicted they would likely have difficulty obtaining sufficient vaccine to cover commercially insured patients, and 32% were likely to have difficulty getting sufficient vaccine to cover Medicaid, underinsured, and uninsured patients because of ordering or distribution problems. Approximately 78% of respondents cited borderline or poor reimbursement for influenza vaccinations, and 53% had unused vaccine at the end of the 2008-2009 influenza season. Ninety-six percent of respondents supported school-located influenza vaccination programs in their community for their patients.

CONCLUSIONS

These results indicate awareness by primary care pediatricians in Maryland of the potential difficulties involved in implementing universal influenza vaccinations in their practice and their support of school-located vaccination programs managed by the local health department in their community.

Medicaid reimbursement and the uptake of adolescent vaccines

BACKGROUND

In light of low adolescent vaccination rates, state-level policies that could improve vaccine coverage should be evaluated. Approximately 1/3 of adolescents are eligible, primarily through Medicaid enrollment, to receive vaccines from state-administered Vaccines for Children (VFC) programs. We investigated whether Medicaid reimbursement, the scope of implementation of VFC programs (i.e. limited or universal purchase), and/or presence of school-based vaccine mandates were associated with adolescent vaccination levels.

METHODS

We performed a cross-sectional analysis of state-level associations between these policies and 2009 National Immunization Survey-TEEN vaccination rates for tetanus-containing, meningococcal conjugate (MCV4), and among females only, human papillomavirus (HPV) vaccines.

RESULTS

Medicaid reimbursement was not associated with vaccine coverage rates after adjusting for presence of vaccine-related school mandates, type of VFC program, proportion of adolescents attending preventive care visits, and state-specific distribution of insurance coverage. Participation in a more expansive VFC program (universal or universal-select) was significantly associated with HPV vaccine coverage, but not tetanus-containing vaccine or MCV4, among states that had mandates for any vaccines.

CONCLUSIONS

Our results suggest that, contrary to what has been shown for childhood vaccines, raising Medicaid reimbursement rates may not improve adolescent vaccine utilization. Instead, other policy changes may be more effective, such as expansion of VFC programs into universal purchase programs, further implementation of school-based vaccine mandates and efforts to raise preventive care visits among adolescents.

How to improve influenza vaccination rates in the U.S

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.

Related factors of age-appropriate immunization among urban-rural children aged 24-35 months in a 2005 population-based survey in Nonsan, Korea

PURPOSE

This study was aimed to determine the status and related factors of age-appropriate immunization among urban-rural children aged 24-35 months in a 2005 population-based survey in Nonsan, Korea.

MATERIALS AND METHODS

We conducted household survey and provider check using questionnaire and checklist to obtain data on immunization status for children, aged 24-35 months. Age-appropriate immunization was defined as status of receiving the fourth diphtheria-tetanus-pertussis (4 DTP), 3 Polio, the first measles-mumps-rubella (1 MMR) doses, and the 4 : 3 : 1 series.

RESULTS

Age-appropriate immunization rates were 51.7% for 4 DPT, 88.0% for 3 Polio, 87.9% for 1 MMR, and 50.3% for the 4 : 3 : 1 series. First-born children, lower perceived barrier scores, and higher perception of immunization data were significantly related to age-appropriate immunization.

CONCLUSION

The findings indicated that age-appropriate immunization rate could be improved by implementing reminder/recall service and providing the knowledge about immunization. Identification and consideration related factors would improve immunization rate and age-appropriate immunization.

Association between Medicaid reimbursement and child influenza vaccination rates

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.

Practice and child characteristics associated with influenza vaccine uptake in young children

OBJECTIVES

The objective of this study was to determine both practice and child characteristics and practice strategies associated with receipt of influenza vaccine in young children during the 2004-2005 influenza season, the first season for the universal influenza vaccination recommendation for all children who are aged 6 to 23 months.

METHODS

Clinical and demographic data from randomly selected children who were aged 6 to 23 months were obtained by chart review from a community-based cohort study in 3 US counties. The proportion of children who were vaccinated by April 5, 2005, in each practice was obtained. For assessment of practice characteristics and strategies, sampled practices received a self-administered practice survey. Practice and child characteristics that predicted complete influenza vaccination were determined by using multinomial logistic regression.

RESULTS

Forty-six (88%) of 52 sampled practices completed the survey and permitted chart reviews. Of 2384 children who were aged 6 to 23 months and were studied, 27% were completely vaccinated. The proportion of children who were completely vaccinated varied widely among practices (0%-71%). Most (87%) practices implemented ≥1 vaccination strategy. Complete influenza vaccination was associated with 3 practice characteristics: suburban location, lower patient volume, and vaccination strategies of evening/weekend vaccine clinics; with child characteristics of younger age, existing high-risk conditions, ≥6 well visits to the practice by 3 years of age, and any practice visit from October through January.

CONCLUSIONS

Modifiable factors that were associated with increased influenza vaccination coverage included October to January practice visits and evening/weekend vaccine clinics.

Cost of universal influenza vaccination of children in pediatric practices

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.

Cost of vaccine administration among pediatric practices

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.

Rates of coverage and determinants of complete vaccination of children in rural areas of Burkina Faso (1998-2003)

Background

Burkina Faso's immunization program has benefited regularly from national and international support. However, national immunization coverage has been irregular, decreasing from 34.7% in 1993 to 29.3% in 1998, and then increasing to 43.9% in 2003. Undoubtedly, a variety of factors contributed to this pattern. This study aims to identify both individual and systemic factors associated with complete vaccination in 1998 and 2003 and relate them to variations in national and international policies and strategies on vaccination of rural Burkinabé children aged 12-23 months.

Methods

Data from the 1998 and 2003 Demographic and Health Surveys and the Ministry of Health's 1997 and 2002 Statistical Yearbooks, as well as individual interviews with central and regional decision-makers and with field workers in Burkina's healthcare system, were used to carry out a multilevel study that included 805 children in 1998 and 1,360 children in 2003, aged 12-23 months, spread over 44 and 48 rural health districts respectively.

Results

In rural areas, complete vaccination coverage went from 25.9% in 1998 to 41.2% in 2003. District resources had no significant effect on coverage and the impact of education declined over time. The factors that continued to have the greatest impact on coverage rates were poverty, with its various dimensions, and the utilization of other healthcare services. However, these factors do not explain the persistent differences in complete vaccination between districts. In 2003, despite a trend toward district homogenization, differences between health districts still accounted for a 7.4% variance in complete vaccination.

Conclusion

Complete vaccination coverage of children is improving in a context of worsening poverty. Education no longer represents an advantage in relation to vaccination. Continuity from prenatal care to institutional delivery creates a loyalty to healthcare services and is the most significant and stable explanatory factor associated with complete vaccination of children. Healthcare service utilization is the result of a dynamic process of interaction between communities and the healthcare system; understanding this process is the key to understanding better the factors underlying the complete vaccination of children.

Delivering adolescent vaccinations in the medical home: a new era?

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.

The impact of conjugate pneumococcal vaccination on routine childhood vaccination and primary care use in 2 counties

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.

Impact of vaccine economic programs on physician referral of children to public vaccine clinics: a pre-post comparison

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.

The association between having a medical home and vaccination coverage among children eligible for the vaccines for children program

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.

Estimating medical practice expenses from administering adult influenza vaccinations

Potential business losses incurred vaccinating adults against influenza have not been defined because of a lack of estimates for medical practice costs incurred delivering vaccines. We collected data on vaccination labor time and other associated expenses. We modeled estimates of per-vaccination medical practice business costs associated with delivering adult influenza vaccine in different sized practices. Per-shot costs ranged from USD 13.87 to USD 46.27 (2001 dollars). When compared with average Medicare payments of USD 11.71, per-shot losses ranged from US$ 2.16 to USD 34.56. More research is needed to determine less expensive delivery settings and/or whether third-party payers need to make higher payments for adult vaccinations.

The cost of giving childhood vaccinations: differences among provider types

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.

Physician attitudes and beliefs associated with patient pneumococcal polysaccharide vaccination status

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.

Immunization coverage and Medicaid managed care in New Mexico: a multimethod assessment

BACKGROUND

We wanted to examine the association between Medicaid managed care (MMC) and changing immunization coverage in New Mexico, a predominantly rural, poor, and multiethnic state.

METHODS

As part of a multimethod assessment of MMC, we studied trends in quantitative data from the National Immunization Survey (NIS) using temporal plots, Fisher's exact test, and the Cochran-Armitage trend test. To help explain changes in immunization rates in relation to MMC, we analyzed qualitative data gathered through ethnographic observations at safety net institutions: income support (welfare) offices, community health centers, hospital emergency departments, private physicians' offices, mental health institutions, managed care organizations, and agencies of state government.

RESULTS

Immunization coverage decreased significantly after implementation of MMC, from 80% in 1996 to 73% in 2001 for the 4:3:1 vaccination series (Fisher's exact test, P = .031). New Mexico dropped in rank among states from 30th for this vaccination series in 1996 to 50th in 2001. A significant decreasing trend (Cochran-Armitage P = .025) in coverage occurred between 1996 and 2001. Findings from the ethnographic study revealed conditions that might have contributed to decreased immunization coverage: (1) reduced funding for immunizations at public health clinics, and difficulties in gaining access to MMC providers; (2) informal referrals from managed care organizations and contracting physicians to community health centers and state-run public health clinics; and (3) increased workloads and delays at community health centers, linked partly to these informal referrals for immunizations.

CONCLUSIONS

Medicaid reform in New Mexico did not improve immunization coverage, which declined significantly to among the lowest in the nation. Reduced funding for public health clinics and informal referrals may have contributed to this decline. These observations show how unanticipated and adverse consequences can result from policy interventions in complex insurance systems.

Influence of insurance status and vaccine cost on physicians' administration of pneumococcal conjugate vaccine

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.

Improving the health of infants on Medicaid by collocating special supplemental nutrition clinics with managed care provider sites

OBJECTIVES

This study tested whether collocation of Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) clinics at managed care provider sites improved health care for infants enrolled in Medicaid and WIC.

METHODS

Weights and immunization rates were studied for the 1997 birth cohort of African American infants enrolled in WIC and Medicaid in Detroit, Mich. Infants using traditional WIC clinics and health services were compared with those enrolled under Medicaid in 2 managed care organizations (MCOs), of whom about half obtained WIC services at MCO provider sites.

RESULTS

Compared with other infants, those who used collocated WIC sites either were closer to their age-appropriate weight or had higher immunization rates when recertified by WIC after their first birthday. Specific benefits (weight gain or immunizations) varied according to the priorities at the collocated sites operated by the 2 MCOs.

CONCLUSIONS

Collocation of WIC clinics at MCO sites can improve health care of low-income infants. However specific procedures for cooperation between WIC staff and other MCO staff are required to achieve this benefit.

The vaccines for children program. Policies, satisfaction, and vaccine delivery

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.

Effect of the Vaccines for Children program on physician referral of children to public vaccine clinics: a pre-post comparison

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.
