Regence HMO Oregon

Regence HMO Oregon is a large IPA-model HMO based in Portland, Ore. It serves commercial, Medicaid, and Medicare cost enrollees throughout Oregon and southern Washington. An affiliate of Blue Cross and Blue Shield of Oregon, Regence HMO Oregon built its rural enrollment by acquiring Capitol Health Care, an HMO with rural enrollment; by encouraging rural employers with traditional Blue Cross and Blue Shield of Oregon indemnity and PPO coverage to switch to HMO coverage; and by aggressively contracting with providers statewide to serve Oregon Health Plan (Medicaid) enrollees.     

Managed health care plans in Southern United States municipalities: empirical evidence on choice of plan

This study examines factors that influence choice of Southern municipal government health care plans in the United States. Using survey data, this article specifically examines the managed care offerings of Health Maintenance Organizations (HMO), Preferred Provider Organizations (PPO) and Point of Service (POS) plans. Some of the more interesting empirical results indicate that HMO plans are associated more with employee satisfaction; PPO plans are associated with cost containment; and POS plans are more likely to provide health care benefits to part-time employees. Empirical evidence also indicates that employee satisfaction is increased when there is a greater choice of managed care plans available to municipal governments.     

Managed Care and Employer Premiums

This paper used 1993–1997 data from medium and large size employers to examine the effects of market wide managed care penetration on the premiums paid for employer sponsored health insurance. Regressions were run for weighted average single coverage premiums and for premiums on conventional, HMO, and PPO coverage. Four findings emerged from the analysis. First, increased managed care penetration had no statistically significant effect on weighted average employer premiums. Second, higher HMO penetration resulted in lower HMO premiums but higher conventional and PPO premiums. Third, higher PPO penetration had no statistically meaningful effects across plan types. Finally, the results depended critically on whether firms offered self-insured plans. Higher levels of HMO penetration led to smaller increases in conventional and PPO premiums for firms with self-insured plans, but also yielded smaller premium reductions from HMOs relative to those with purchased coverage.     

Health maintenance organizations: the beginning or the end?

This article describes the changes taking place in a mature HMO market that has been identified as a bellwether HMO community, the Minneapolis-St. Paul metropolitan area. We describe how this market--previously characterized by traditional HMOs and traditional fee-for-service plans--has been transformed within the past five years into a market with a variety of plans competing on the dimensions of premiums, provider choice, and coverage. Among the most significant changes are the evolution of the local Blue Cross and Blue Shield plan into a form resembling an individual practice arrangement (IPA) with broad coverage and broad provider choice, and the appearance of preferred provider plans sponsored by the HMOs. We suggest that such changes have blurred the distinction between health plan types, making traditional plan designations no longer valid for either health policy analysis or health services research. For example, studies contrasting the performance of HMOs and fee-for-service plans should concentrate instead on the various dimensions of these plans, such as coverage and openness of provider choice. The article is intended to stimulate discussion and to suggest a new framework for describing health plan competition.     

Selection of health insurance by an employee group in Northern California.

Enrollment trends for a large employee group were analyzed to determine the extent to which consumers chose Blue Cross or Health Maintenance Organization (HMO) health insurance under various premium differentials. Data were collected from employment records of six University of California campuses for the period 1967 to 1978. Enrollment in the Kaiser Foundation Health Plan (an HMO) more than doubled during this period while enrollment in Blue Cross remained relatively stable. This increased preference for Kaiser coverage was associated with a concurrent relative rise in costs to employees of Blue Cross coverage. These data suggest that consumers are sensitive to insurance costs, and that given the opportunity HMOs can compete effectively with traditional health insurance.     

Health Promotion and Managed Care:: Surveys of California’s Health Plans and Population

Introduction:The purpose was to examine whether health-promotion programs offered by California health plans are a serious attempt to improve health status or a marketing device used in an increasingly competetive marketplace. The research examined differences in the coverage, availability, utilization, and evaluation of health-promotion programs in California health plans.Methods:A mail survey was done of the 35 HMOs (86% response) and 18 health insurance carriers (83% response) licensed to sell comprehensive health insurance in California in 1996 (some plans sell both HMO and PPO/indemnity products). The final sample included 30 commercial HMOs and 20 PPO and indemnity plans. The 1996 California Behavioral Risk Factor Survey (BRFS) of 4,000 adults was used to estimate population participation rates in health-promotion programs.Results:California’s HMOs in 1996 offered more comprehensive preventive benefits and health-promotion programs compared to PPO and indemnity plans. HMOs relied on a more comprehensive set of health-education methods to communicate health information to members and were more likely to open their programs to the public. HMOs are also more likely to have developed relationships with community-based and public health providers. Participation in health-promotion programs is low (2%–3%), regardless of plan type, and most health plans limit evaluations to assessment of member satisfaction and utilization. Only 35%–45% of HMOs, and no PPO/indemnity plans, assess the impact of health-promotion programs on health risks and behaviors, health status, or health care costs.Conclusion:For the majority of California’s PPO and indemnity plans, health promotion is not an integral part of their business. For the majority of HMOs, health-promotion programs are offered primarily as a marketing vehicle. However, a substantial minority of HMOs offer health-promotion programs to achieve other organizational goals of health improvement and cost control.     

Health care experience among employees prior to and after enrollment in a prepaid health insurance plan (HMO)

Company medical and benefit records of employees who were enrolled in prepaid health insurance plans (HMOs) in Minneapolis, Washington, D.C., and Seattle were reviewed for hospital and surgical utilization prior to as well as after their enrollment. Comparisons were made for the same calendar periods with closely matched employees who were covered by Blue Cross/Blue Shield (BC/BS). The results indicate that after enrollment the HMO subjects at each location had lower rates for hospital and surgical utilization than the BC/BS controls. For the period prior to enrollment, during which time coverage was through BC/BS, the prospective HMO subjects at two locations had lower hospital and surgical utilization than the controls. Possible explanations of this potential self-selection bias are discussed.     

The Impact of State Policies on Vaccine Coverage by Age 13 in an Insured Population

PurposeTo determine the impact of state policies on vaccine coverage among adolescents with managed care insurance.MethodsWe used the 2003 Health Plan Employer Data and Information Set to determine state-specific hepatitis B and varicella vaccine coverage among children with managed care insurance who turned 13 years in 2002. Our outcomes of interest were receipt of hepatitis B and varicella vaccines by age 13. Utilizing weighted least-squares methods, multiple linear regression models were developed to evaluate the relationship between hepatitis B and varicella vaccine coverage and state policies, while controlling for state sociodemographic variables.ResultsAcross 28 states, adolescent hepatitis B vaccine coverage ranged from 35.3% to 80.5% (mean = 55.3%) and varicella vaccine coverage ranged from 22.9% to 7.6% (mean = 42.3%). In separate multiple regression models, after adjusting for potentially confounding sociodemographic variables, middle school mandates were significantly associated with hepatitis B vaccine coverage (p = .002) and varicella vaccine coverage (p = .024). Other policies, including universal purchase of vaccines and availability of philosophic exemptions, were not associated with vaccine coverage in this insured population.ConclusionsIn this population of insured adolescents, middle school vaccine mandates were the only state policy associated with improved hepatitis B and varicella vaccine coverage. Mandates are an effective method for promoting adolescent immunization.

Socioeconomic characteristics associated with the introduction of new vaccines and full childhood vaccination in Ghana, 2014

BackgroundChildhood vaccination in Ghana has historically been high, but the impact of recently introduced vaccines on coverage is unknown. We calculate vaccine coverage of Ghanaian children– contrasting newly introduced vaccines and those long available – and describe associations between sociodemographic indicators and full vaccination.MethodsData from the 2014 Ghana Demographic and Health Survey was used to calculate full vaccination, defined as receipt of one dose bacillus Calmette-Guérin (BCG); two doses of rotavirus vaccine; 3 doses of pentavalent vaccine, oral polio vaccine (OPV), and pneumococcal conjugate vaccine (PCV); and one dose of measles-rubella vaccine and yellow fever vaccine, among children age 12–24 months. Logistic regression with survey procedures was used to estimate odds ratios for socioeconomic factors’ association with full vaccination.ResultsThe sample comprised a total of 1107 children 12–24 months. Full vaccination coverage was 70.8%. Vaccination coverage was higher for vaccines administered at younger ages (e.g., birth dose of BCG was 97.0%) than at older ages (e.g., yellow fever at 9 months was 88.2%). Newly introduced vaccines had lower coverage: at 10 weeks, pentavalent 2 was 95.4%, versus 91.2% for PCV 2 and 88.8% for rotavirus 2. Living outside of Greater Accra, home delivery, younger maternal age, urban residence, and more than one child under five in the home were all associated with decreased odds of full vaccination in the adjusted analysis whereas sex of the child, wealth, religion, and maternal education were not associated with full vaccination status.ConclusionGhana has high overall vaccination rates although disparities in full vaccination by sociodemographic status exist. As vaccine recommendations are revised, it will be important to insure equitable access to vaccination for all children regardless of demographic and socioeconomic background.     

Competition between non-profit and for-profit health insurers

This study investigates the effects of tax, regulatory, and reimbursement policies and other factors exogenous to the health insurance market on the relative price (to commercial insurers) paid by Blue Cross plans for hospital care, their administrative expense and accounting profits, premiums, and ultimately Blue Cross market share. We specify and estimate a simultaneous equation model to assess interrelationships among these variables. We conclude that premium tax advantages enjoyed by the Blues have virtually no effect on the Blues' premiums or their market shares. A Blue Cross plans' market share has a positive effect on the discount it obtains from hospitals as does coverage of Blue Shield charges by a state-mandated rate-setting plan. An upper bound on the effect on the Blue Cross market share of covering Blue Cross under rate-setting but excluding the commercials from such coverage is seven percentage points. Tests for administrative slack in the operation of Blue Cross plans yield mixed results.     

Chicago project provides insights into improving managed care

Managed care enrollees are generally more satisfied with their HMO, PPO, and POS plans than their employers expected they'd be. But both consumers and employers think health plans can improve on member services and efficient delivery of care. These results come from a Chicago Business Group on Health project involving 14 employers, 7 health plans, and 22,000 surveyed employees. The study's multi-dimensional design and emphasis on improving health plan performance make it a model from which others may learn.     

The Impact of Ownership Conversions on HMO Performance

Recently, several Blue Cross plans that sponsor Health Maintenance Organizations (HMOs), among other insurance products, have sought regulatory approval to convert from a not-for-profit to a for-profit entity. We examine the impact of not-for-profit HMOs converting to for-profit status in a fixed-effects framework using HMO level data from InterStudy. Our findings indicate conversions to for-profit status do not significantly impact HMO prices, profit margins, use of hospital days or ambulatory visits, and the provision of Medicare and Medicaid products.     

Vaccines against Neisseria meningitidis serogroup B strains – What does genomics reveal on the Portuguese strain’s coverage

In Portugal, Neisseria meningitidis serogroup B (MenB) is the most common serogroup causing invasive meningococcal disease. To protect against MenB disease two protein based MenB vaccines are available in Portugal, the 4CMenB that was licenced in 2014 and included in the routine immunization program in October 2020, and the bivalent rLP2086 vaccine licensed in 2017. The aim of this study was to predict the coverage of the 4CMenB and rLP2086 vaccines against Portuguese isolates of Neisseria meningitidis sampled between 2012 and 2019 and to evaluate the diversity of vaccine antigens based on genomic analysis.Whole-genome sequence data from 324 Portuguese Neisseria meningitidis isolates were analysed. To predict strain coverage by 4CMenB and rLP2086, vaccine antigen reactivity was assessed using the MenDeVar index available on the PubMLST Neisseria website.This study included 235 (75.6%) MenB isolates of all invasive MenB strains reported between 2012 and 2019. Moreover, 89 non MenB isolates sampled in the same period, enrolling 68 from invasive disease and 21 from healthy carriers, were also studied.The predicted strain coverage of MenB isolates was 73.5% (95% CI: 64.8%–81.2%) for 4CMenB and 100% for rLP2086. Predicted strain coverage by 4CMenB in the age group from 0 to 4 years old, was 73.9%. Most of MenB isolates were covered by a single antigen (85.4%), namely fHbp (30.3%), P1.4 (29.2%), and NHBA (24.7%).In Portugal, the most prevalent peptides in MenB isolates were: P1.4 (16.2%), NHBA peptide 2 (14.0%), and fHbp peptide 14 (7.2%), from 4CMenB and fHbp peptide 19 (10.6%) from rLP2086. No significant temporal trends were observed concerning the distribution and diversity of vaccine antigen variants.4CMenB and rLP2086 vaccines showed potential coverage for isolates regardless serogroup.The use of both vaccines should be considered to control possible outbreaks caused by serogroups with no vaccine available.     

Billing and payment of commercial and Medicaid health plan adult vaccination claims in Michigan since the Affordable Care Act

BackgroundProvider concern regarding insurance non-payment for vaccines is a common barrier to provision of adult immunizations. We examined current adult vaccination billing and payment associated with two managed care populations to identify reasons for non-payment of immunization insurance claims.MethodsWe assessed administrative data from 2014 to 2015 from Blue Care Network of Michigan, a nonprofit health maintenance organization, and Blue Cross Complete of Michigan, a Medicaid managed care plan, to determine rates of and reasons for non-payment of adult vaccination claims across patient-care settings, insurance plans, and vaccine types. We compared commercial and Medicaid payment rates to Medicare payment rates and examined patient cost sharing.ResultsPharmacy-submitted claims for adult vaccine doses were almost always paid (commercial 98.5%; Medicaid 100%). As the physician office accounted for the clear majority (79% commercial; 69% Medicaid) of medical (non-pharmacy) vaccination services, we limited further analyses of both commercial and Medicaid medical claims to the physician office setting. In the physician office setting, rates of payment were high with commercial rates of payment (97.9%) greater than Medicaid rates (91.6%). Reasons for non-payment varied, but generally related to the complexity of adult vaccine recommendations (patient diagnosis does not match recommendations) or insurance coverage (complex contracts, multiple insurance payers). Vaccine administration services were also generally paid. Commercial health plan payments were greater for both vaccine dose and vaccine administration than Medicare payments; Medicaid paid a higher amount for the vaccine dose, but less for vaccine administration than Medicare. Patients generally had very low (commercial) or no (Medicaid) cost-sharing for vaccination.ConclusionsAdult vaccine dose claims were usually paid. Medicaid generally had higher rates of non-payment than commercial insurance.     

Use of ambulatory care services in three provider plans: interactions between patient characteristics and plans

A previous study of low-income enrollees in a closed-panel health maintenance organization (HMO) and a Blue Cross/Blue Shield (BC/BS) plan showed that the effect on the use of health services of the age, sex, health status, previous health care use, race, and family size of the enrollees was different in the two plans. We have replicated this study using the same two provider plans but studying a different group of white collar, middle class enrollees. A third plan, an experimental independent practice association (IPA), was also available for analysis. Utilization was defined as use (yes/no) and the quantity of use for those who used services (in standardized dollars). Significant interactions were detected between plan and all of the independent variables but race. The use of services in the HMO was least affected by enrollees' characteristics (age, sex, race, health status, prior use, family size) and use was most sensitive to patient characteristics in BC. In some respects, the IPA was more like the HMO and in other respects more like the BC/BS plan.     

Evaluation of potentially achievable vaccination coverage with simultaneous administration of vaccines among children in the United States

BackgroundRoutine administration of all age-appropriate doses of vaccines during the same visit is recommended for children by the National Vaccine Advisory Committee (NVAC) and the Advisory Committee on Immunization Practices (ACIP).MethodsEvaluate the potentially achievable vaccination coverage for ≥4 doses of diphtheria and tetanus toxoids and acellular pertussis vaccine (4+DTaP), ≥4 doses of pneumococcal conjugate vaccine (4+PCV), and the full series of Haemophilus influenzae type b vaccine (Hib-FS) with simultaneous administration of all recommended childhood vaccines. Compare the potentially achievable vaccination coverage to the reported vaccination coverage for calendar years 2001 through 2013; by state in the United States and by selected socio-demographic factors in 2013. The potentially achievable vaccination coverage was defined as the coverage possible for the recommended 4+DTaP, 4+PCV, and Hib-FS if missed opportunities for simultaneous administration of all age-appropriate doses of vaccines for children had been eliminated.ResultsCompared to the reported vaccination coverage, the potentially achievable vaccination coverage for 4+DTaP, 4+PCV, and Hib-FS could have increased significantly (P < 0.001), the vaccination coverage would have achieved the 90% target of Healthy People 2020 for the three vaccines beginning in 2005, 2008, and 2011 respectively. In 2013, the potentially achievable vaccination coverage increased significantly across all selected socio-demographic factors, potentially achievable vaccination coverage would have reached the 90% target for more than 51% of the states in the United States.ConclusionsThe findings in this study suggest that fully utilization of all opportunities for simultaneous administration of all age-eligible childhood doses of vaccines during the same vaccination visit is a critical strategy for achieving the vaccination coverage target of Healthy People 2020. Encouraging providers to deliver all recommended vaccines that are due at each visit by implementing client reminder and recall systems might decrease missed opportunities for simultaneous administration of childhood vaccines.     

The connection between COVID-19 vaccine abundance,vaccination coverage,and public trust in government across the globe

This study investigates that how the number of COVID-19 vaccines secured correlates with the vaccination coverage (full and booster) depending on whether or not there is trust in national government across 47 countries. The data are based on global figures as of Nov. 2021 and Feb. 2022 while measures for confidence in government is according to Gallup World Poll, Oct. 2021. The model includes an interaction term of these two predictors, also controls for a range of socio-economic factors and country specific variables. The results indicate a non-linear and mixed relationship between the numbers secured, the public trust, and the vaccination rate. In Feb. 2022, with confidence in government, securing number of vaccines to cover 200% of the population (or more) increased the full vaccination rate by 12.26% (95% CI: 11.70–12.81); where number secured was 300% (or more), the coverage increased by 7.46% (95% CI: 6.95–7.97). Under similar scenarios, rate of booster shots increased by 13.16% (95% CI: 12.62–13.70; p < 0.01) and 14.36% (95% CI: 13.86–14.85; p < 0.01), respectively. Where the number secured fell below 200%, confidence in government had a revers relationship with the rate of full vaccination (?2.65; 95% CI: ?3.32 to ?1.99), yet positive with the rate of booster shots (1.65; 95% CI: 1.18–2.12). These results indicate that better success can be achieved by a combination of factors including securing sufficient number of vaccines as well as improving the public trust. Vaccine abundance, however, cannot be translated into greater success in vaccination coverage. This study highlights the importance of efficiency in acquiring vaccine resources and need for improvement in public belief in immunization programmes rather than stock piling.     

Reproductive and sexual health benefits in private health insurance plans in Washington State

CONTEXT: Although unintended pregnancy and sexually transmitted diseases (STDs) are considerable problems in the United States, private health insurance plans are inconsistent in their coverage of reproductive and sexual health services needed to address these problems. METHODS: A survey administered to a market-representative sample of 12 health insurance carriers in Washington State assessed benefit coverage for gynecologic services, maternity services, contraceptive services, pregnancy termination, infertility services, reproductive cancer screening, STD services, HIV and AIDS services, and sterilization, as well as for the existence of confidentiality policies. "Core" services in each category were defined based on U.S. Preventive Services Task Force and other recommendations. RESULTS: Of the 91 top-selling plans on which data were collected, 8% were indemnity plans, 14% were point-of-service plans, 21% were preferred-provider organization plans and 57% were health maintenance organization (HMO)-type products; they had a combined enrollment of 1.4 million individuals. Coverage of core services varied widely by type of plan. While a high proportion of plans covered core gynecologic, maternity, reproductive cancer screening, STD and HIV and AIDS services, nearly half of plans did not cover any kind of contraceptive method. Approximately 13% of female enrollees did not have core coverage for gyneco!ogic services, 19% for matemity services, 75% for contraception, 37% for sterilization and 53% for pregnancy termination; 98% of women and men were not covered for infertility treatment. Most carriers did not have specific policies for maintaining privacy of sensitive health information. Overall, benefit coverage was lower for indemnity, preferred-provider organization and HMO plans in Washington State than has previously been seen nationally. CONCLUSIONS: A sizable proportion of women and men in Washington State who rely on private-sector health insurance lack comprehensive coverage for key reproductive and sexual health services.     

Vaccination coverage among children enrolled in Head Start programs or day care facilities or entering school.

PROBLEM/CONDITION: Undervaccinated children enrolled in day care centers and schools are vulnerable to outbreaks of vaccine-preventable diseases. A Healthy People 2000 objective is to increase to > or = 95% vaccination coverage among children attending licensed day care facilities and kindergarten through postsecondary school (objective 20.11). REPORTING PERIOD COVERED: September 1997-June 1998. DESCRIPTION OF SYSTEM: CDC's National Immunization Program administers grants to support 64 vaccination programs. These programs are in all 50 states, eight territories or jurisdictions (American Samoa, Republic of Marshall Islands, Federated States of Micronesia, Guam, Commonwealth of Northern Mariana Islands, Puerto Rico, Republic of Palau, and the U.S. Virgin Islands), five cities (Chicago, Houston, San Antonio, New York City, and Philadelphia), and the District of Columbia. Grant guidelines require annual school vaccination surveys and biennial surveys of Head Start programs and licensed day care facilities. This system constitutes the only source of nationally representative vaccination coverage estimates for these populations. RESULTS: Head Start Programs: Of the 64 reporting areas, 33 (51.6%) submitted coverage levels for children enrolled in Head Start programs. Of these, all 33 programs reported coverage levels for diphtheria and tetanus toxoids and pertussis vaccine (DTP), diphtheria and tetanus toxoids (DT), or tetanus toxoids (Td), poliovirus vaccine, and measles vaccine; and 32 reported coverage levels for mumps and rubella vaccines. Four programs reported coverage levels for the combined measles, mumps, and rubella vaccine (MMR). The mean vaccination coverage levels for the 1997-98 school year among the reporting vaccination programs were 97.8% for poliovirus vaccine (range: 80.0%-100.0%), 97.0% for DTP/DT/Td (range: 87.7%-100.0%), 93.3% for measles vaccine (range: 91.4%-100.0%), and 93.2% for mumps and rubella vaccines (range: 91.4%-100.0%). Licensed Day Care Facilities: Of the 63 reporting areas with licensed day care facilities, 38 (60.3%) submitted coverage levels for enrolled children. Of these, all 38 programs reported coverage levels for poliovirus vaccine and DTP/DT/Td, 37 reported coverage levels for measles vaccine, and 36 reported coverage levels for mumps and rubella vaccines. Four programs reported coverage levels for the combined MMR. The mean vaccination coverage levels among the reporting areas were 95.8% for poliovirus vaccine (range: 85.1%-99.8%), 95.7% for DTP/DT/Td (range: 77.6%-99.9%), 89.1% for measles vaccine (range: 78.0%-99.9%), and 89.1% for mumps and rubella vaccines (range: 78.0%-99.9%). Kindergarten/First Grade: Of the 64 reporting areas, 43 (67.2%) submitted coverage levels for children enrolled in kindergarten and first grade. Of these 43 programs, 42 reported coverage levels for poliovirus vaccine and DTP/DT/Td, and 43 reported coverage levels for measles, mumps, and rubella vaccines. Four of the 43 programs reported coverage levels for the combined MMR. The mean vaccination coverage levels among the reporting areas were 96.7% for poliovirus vaccine (range: 82.8%-99.9%), 96.7% for DTP/DT/Td (range: 82.8%-99.8%), 96.0% for measles vaccine (range: 82.8%-99.9%), and 96.5% for mumps and rubella vaccines (range: 82.8%-99.9%). INTERPRETATION: High levels of vaccination coverage among children entering school most likely result from the successful implementation of state-specific school vaccination laws, which have applied to children entering school in all states and the District of Columbia since at least 1990. All states, territories, and the District of Columbia have additional laws that require vaccination of children in licensed day care facilities. However, because a high proportion of states and territories did not submit vaccination coverage reports to CDC, these estimated means may not reflect levels for all children in the United States.
