Granulation tissue regression induced by musculocutaneous advancement flap coverage.

BACKGROUND: Clinical experience suggests that granulation tissue may be inhibited by coverage with a musculocutaneous flap. We hypothesized that coverage of an open wound with a musculocutaneous flap would result in regression and apoptosis of the wound's granulation tissue. METHODS: In the first experiment, 32 rats underwent excisional wounding; 16 underwent musculocutaneous flap coverage of their granulation tissue on postwounding day 8, and then 16 rats (8 controls + 8 flaps) were killed on both postwounding days 10 and 12 (2 and 4 days after the flap procedure, respectively). In the second experiment, 18 rats were wounded, and on postwounding day 5 the rats underwent flap coverage (n = 6), wound edge release/mobilization (the first step of the flap procedure) without flap coverage (n = 6), or dressing change only (n = 6); all rats were killed on postwounding day 6 (24 hours after the secondary intervention). Apoptosis was quantified with the terminal deoxynucleotidyl transferase-mediated nick-end labeling assay. RESULTS: Placement of a musculocutaneous flap over an 8-day-old excisional wound in the first experiment increased the apoptotic rate in the granulation tissue from 0% to 1% (controls) to 5% to 10% at both 2 and 4 days after flap coverage (P <.05). Cell population density decreased 50% in the flap-covered granulation tissue compared with the controls (P <.05). In the second experiment, circumferential release of the granulation tissue resulted in an equivalent increase in granulation tissue apoptosis over controls compared to that induced by the full flap procedure. CONCLUSIONS: Coverage of established granulation tissue with a musculocutaneous flap resulted in histologic regression of the wound's granulation tissue after 2 to 4 days of flap coverage and induced at least a 5-fold increase in the apoptotic rate of the granulation tissue. Releasing the wound edge increased granulation tissue apoptosis to a level equivalent to that produced by the musculocutaneous flap procedure, suggesting that alteration of the wound's mechanical environment is responsible for the acute induction of apoptosis in this model.

Factors affecting immunization coverage levels in a district of India.

Immunization coverage is measured to assess the performance of the Expanded Programme on Immunization. In 1988 we conducted a coverage survey among 12-23 month-old children in the North Arcot District (population 5,007,746) in southern India. In each of the 12 towns a 30-cluster sample survey was conducted. In the 35 rural blocks with 1590 panchayats, 159 were selected systematically and all children (n = 7300) were surveyed. In the towns, coverage ranged for measles vaccine from 29 to 53%, BCG from 65 to 91% and OPV and DPT third dose from just over 60% to just over 80%. In the rural areas, coverage ranged for measles vaccine from 10.8 to 19.3%, BCG 25.1-34.1%, DPT third dose 42.2-50.4% and OPV third dose 39.6-48%. In the towns, 25, 66, 67 and 59% of BCG, DPT, OPV and measles vaccines had been provided by private agencies showing that availability of vaccines throughout the week and easy access even in payment terms played an important role in achieving higher levels of coverage compared with rural areas where all vaccines are given by Government agencies, free of charge. In the rural areas, significantly large variations in coverage were seen among panchayats--large and peri-urban panchayats had significantly better coverage than small and more rural panchayats. Within any given block (the population unit consisting of 30-40 panchayats served by a Primary Health Centre), there were large variations in the levels of immunization coverage between panchayats.(ABSTRACT TRUNCATED AT 250 WORDS)

Universal health care coverage--pitfalls and promise of an employment-based approach.

America's patchwork quilt of health care coverage is coming apart at the seams. The system, such as it is, is built upon an inherently problematic base: employment. By definition, an employment-based approach, by itself, will not assure universal coverage of the entire population. If an employment-based approach is to be the centerpiece of a system that provides universal coverage, special attention must be paid to all the categories of individuals who are not employees--children, unemployed spouses or singles, the unemployable ill and disabled, persons between jobs, students, retirees, the elderly. Moreover, in a purely voluntary employment-based arrangement, some employers will not provide insurance at all, and others will provide inadequate coverage, necessitating other special provisions for coverage. As a consequence, about one out of six people now has no health coverage whatsoever, and even more have inadequate coverage. All the while, the rapidly-increasing transaction costs of sustaining this grossly inadequate pluralistic system eat up sufficient funds to provide basic benefits to the entire population. The time for systematic reforms has come and gone; what is now needed is action to prevent disaster, followed by a complete rebuilding of this country's health coverage system. Although perhaps more likely to be tried than more radical, completely nationalized, ones, stepwise reforms may not go far enough to cure the significant ills of the current employment-based system. Passage of inadequate reforms, then, could well set the stage for nationalized health care in the not too distant future.

Hepatitis B vaccination coverage among United States children.

BACKGROUND: In 1991 the Advisory Committee on Immunization Practices recommended vaccination of all infants with three doses of hepatitis B virus vaccine (HepB) by 18 months of age as a key component of a comprehensive strategy to eliminate hepatitis B virus transmission in the United States. The American Academy of Pediatrics and the American Academy of Family Physicians published similar recommendations soon afterward. METHODS: Data were obtained from the National Immunization Survey, a survey that began in 1994 and is conducted quarterly by the Centers for Disease Control and Prevention to estimate vaccination coverage among noninstitutionalized US children 19 to 35 months of age. RESULTS: The 1999 National Immunization Survey data indicate that approximately 88.1% (95% confidence interval, 87.4, 88.8) of children 19 to 35 months of age had received at least three doses of HepB (HepB3). There has been a consistent increase in HepB3 coverage since 1994. However, the rate of increase has slowed in recent years and HepB3 coverage remains lower than coverage attained with three doses of diphtheria-tetanus-pertussis and Haemophilus influenzae vaccines. HepB3 coverage varied slightly by race/ethnicity and was highest among white and Asian children (89%). Coverage also varied by state; 26 states had levels of at least 90%. CONCLUSIONS: Since the 1991 recommendations for universal hepatitis B vaccination, there has been a dramatic increase in coverage levels among children 19 to 35 months of age. However, the Childhood Immunization Initiative goal of 90% coverage has not been reached. Therefore continued efforts are needed to protect US children against this serious but preventable infection.

The effect of insurance coverage changes on drug utilization in HIV disease.

BACKGROUND: Insurance coverage facilitates access to life-saving medications for many patients with HIV disease. Thus, the effects of insurance coverage changes, such as the gain or loss of coverage, may be important in explaining patient access and adherence to the medications used in the treatment of HIV disease. OBJECTIVES: The study's objective was to examine whether changes in health insurance coverage affect rates of prescription drug use by patients with HIV disease. METHODS: Data were ascertained from adults participating in a series of up to six interviews as part of the AIDS Costs and Services Utilization Survey (ACSUS). ACSUS was an 18-month panel survey of patients in care for HIV/AIDS at 26 sites located in 10 U.S. cities. Poisson regression analyses with generalized estimating equations were conducted to determine the effects of demographic and socioeconomic variables on the acquisition rate of antiretrovirals, antipneumocystics, and antidepressants. The analytic sample consisted of 1566 respondents who provided 6518 interviews. RESULTS: Although changes in insurance coverage were common, complete loss of insurance was reported in only 1.5% of the interviews whereas gaining insurance was reported in 3.3% of interviews. Having no coverage was associated with significantly lower rates of antiretroviral (rate ratio [RR], 0.73), antipneumocystic (RR, 0.58) and antidepressant use (RR, 0.31). Gaining insurance coverage was associated with lower antiretroviral (RR, 0.75) and antipneumocystic (RR, 0.70) use whereas losing insurance was associated with lower antiretroviral use (RR, 0.58). In multivariate analyses, these associations remained. CONCLUSIONS: Changes in health insurance coverage are associated with lower rates of drug use for some medications used by patients with HIV disease.

Vaccine coverage: recent trends and future prospects.

OBJECTIVE: To assess the feasibility of achieving the target of 95% coverage for the childhood immunisation schedule by 1995 and to determine the influence of sociodemographic factors and information systems on recent trends. DESIGN: Analyses of trends in quarterly vaccination data for diphtheria, pertussis, and measles in health districts between February 1988 and February 1991. SETTING: District health authorities in England and Wales, and health and social services boards in Northern Ireland. SUBJECTS: Cohorts of children whose youngest member had reached the target age of 18 months for receiving the third doses of diphtheria and pertussis vaccines and 2 years for receiving measles vaccine. RESULTS: Predicted coverage levels for mid-1995 were in excess of 95% for diphtheria, pertussis, and measles vaccines. In the 118 districts that continuously reported between February 1988 and February 1991 the increase in coverage was 6% for diphtheria and 13% for pertussis and measles vaccines. 1991 coverage depended primarily on 1988 coverage. The additional effects of deprivation, change in computer system, and child population size achieved at most only marginal statistical significance. CONCLUSIONS: The government's target of 95% coverage by 1995 is realistic, although projections should be viewed with caution. Several national vaccination initiatives are likely to have contributed to the recent steady increase in coverage. Updating and validation exercises are likely to improve recorded coverage.

Association between interruptions in medicaid coverage and use of inpatient psychiatric services.

OBJECTIVES: Persons with schizophrenia are heavy and persistent users of Medicaid services. Interruptions in their Medicaid coverage may have serious consequences for the mental health of these individuals and their subsequent use of mental health services. This study sought to determine the impact of interruptions in Medicaid coverage on the use of Medicaid-reimbursed inpatient psychiatric services over a four-year period. METHODS: Inpatient Medicaid claims and eligibility files for 1,830 Medicaid beneficiaries with schizophrenia in Utah from December 1990 to December 1994 were used to identify differences in hospital admissions and total number of days in a hospital associated with interrupted Medicaid coverage. Of the 1,830 Medicaid beneficiaries identified, 1,463 experienced continuous Medicaid eligibility, and 367 had interruptions in their eligibility. RESULTS: Interruptions in Medicaid coverage were associated with an average of.63 more psychiatric hospitalizations per beneficiary over the four-year period, representing an 86 percent higher hospital admission rate. This increase appeared to be largely due to a subset of persons who have much higher hospitalization rates after an interruption in Medicaid coverage. Interruptions in Medicaid coverage were associated with a mean of 8.3 more days of psychiatric hospitalization over the four-year period, representing 61 percent more hospital days. CONCLUSIONS: Medicaid beneficiaries who experience interruptions in coverage have, on average, a significantly greater use of inpatient psychiatric services while participating in Medicaid than beneficiaries with continuous Medicaid coverage. These findings suggest potential benefits of maintaining continuous Medicaid eligibility for beneficiaries with a severe mental illness.

Employer-sponsored insurance coverage for alcoholism and drug-abuse treatments.

This article examines the growth in employer-sponsored health insurance coverage for alcoholism and drug-abuse treatments. Data are drawn from the Bureau of Labor Statistics' Employee Benefit Surveys of 1981, 1983 and 1985. The surveys provide information on approximately 20.5 million full-time permanent employees in 43,000 establishments each year. The data are nationally representative. In 1985, 68.5% of employees with medical insurance had coverage for alcoholism treatments and 61.6% had coverage for drug-abuse treatments. Alcoholism coverage increased 89% from 1981 to 1985. The increases were reflected across all regions, firm sizes and occupational groups. Self-insured firms, exempt from mandated coverage laws, had the greatest increase in coverage. HMOs appear to have reduced coverage since 1981. Finally, substance abuse coverages did not appear to be discretionary and, therefore, were unlikely to be eliminated if tax laws on fringe benefits were changed.

[Assessment of vaccination coverage of the basic schedule for the 1st year of life].

Immunization coverage was evaluated in all 12-23 month-old children living in the area were five years before a Primary Care Practice had been set up. All children were investigated through home visits, checking of the immunization chart and relying on mothers' information. In 1986, a baseline study had identified an immunization coverage of under 60% for each of the scheduled vaccines. The current study confirmed that coverage was of 87% for three doses of DTP, 89% for Sabin, 88% for one dose of measles vaccine and 79% for BCG. Despite the high coverage achieved for each specific vaccine, when the basic schedule for the first year was verified, it was observed that only 75% of the children had received the full scheme. Immunization coverage is uneven in different census tracts, being higher in the poorest and more remote areas, where seam the health was given extra attention. A comparison with the routine administrative evaluation of the immunization coverage showed that this underestimated the real coverage. Maternal immunization uptake was also evaluated (antitetanus vaccine during pregnancy) and only 49% of the women were found to be adequately protected. The information collected led to a reorganization of the whole immunization program in a 100% coverage.

Vaccine preventable diseases and vaccination coverage in Australia, 1993-1998.

BACKGROUND: Since the introduction of childhood vaccination for diphtheria in 1932 and the widespread use of vaccines to prevent tetanus, pertussis (whooping cough) and poliomyelitis in the 1950s, deaths in Australia from vaccine preventable diseases (VPDs) have declined by more than 99%. It is important, however, that the downward trend in morbidity and mortality from VPDs is maintained and carefully monitored, and that changes are interpreted in relation to vaccination coverage. AIM: This report aimed to bring together three national sources of routinely collected data on the morbidity and mortality (notifications, hospitalisations and deaths) from VPDs during the period 1993-1998 for the 8 diseases then on the routine childhood vaccination schedule, and for 4 other diseases potentially preventable by childhood vaccination. It also examined vaccination coverage for the same period. METHODS: Data sources included notifications from the National Notifiable Diseases Surveillance System (NNDSS), hospitalisation data from the Australian Institute of Health and Welfare (AIHW) National Hospital Morbidity Database, deaths from the Australian Bureau of Statistics (ABS) Causes of Death Collection and vaccination coverage according to the Australian Childhood Immunisation Register (ACIR). All data sources were expected to have some limitations, the most important being under-reporting for notifications and vaccination encounters, and coding errors in the hospital morbidity data. RESULTS: Notifications for the 8 diseases covered by the routine schedule declined by 42%, from an average of 11,537 cases each year in 1993-1997 to 6700 in 1998, and hospitalisations fell by 12%, from an average of 1745 per year to 1536 in 1997/1998, while deaths remained unchanged at 7 each year over the period of review (Table 1). Tetanus caused 1 or 2 of the deaths each year. However, 6 of the 7 deaths in 1997 were in infants during a major outbreak of pertussis. Pertussis caused most of the notifications, hospitalisations and deaths during the review period. While most of these were in children, 46% of the notifications and 13% of the hospitalisations occurred in persons aged 15 years or more. There were notable declines in the numbers of notifications of invasive Haemophilus influenzae type b (Hib) disease in children under 5 years of age (77%), measles (87%) and rubella (75%), and there were no notifications of diphtheria or poliomyelitis. Vaccination coverage estimated using ACIR data increased during the review period. Coverage for the first 3 doses of diphtheria, tetanus, pertussis and Hib vaccines, assessed at 1 year of age, increased from 75% to 85%, while coverage for measles-mumps-rubella (MMR) vaccine, assessed at 2 years of age, increased from 83% to 86%. It is likely that these data underestimated coverage by 5-10%, and that the increase in coverage partly reflected better reporting to the ACIR by providers.

Employment-based health benefits: who is offered coverage vs. who takes it.

This Issue Brief provides data on employment-based health insurance, with a discussion of recent trends and how sponsorship rates, offer rates, coverage rates, and take-up rates vary for different workers. Other sections examine reasons why workers do not participate in employment-based health plans, alternative sources of health insurance, and uninsured workers. In 1997, 83 percent of the 108.1 million wage and salary workers in the United States were employed by a firm that sponsored a health plan. Of those workers, 75 percent were offered coverage, and 62 percent (or 67.5 million workers) were covered by that plan. Of those workers who worked for an employer that offered them a health plan, 83 percent participated in the plan. Sponsorship rates have barely changed in the last 11 years. In 1988, 83 percent of wage and salary workers reported that their employer sponsored a health plan. This declined slightly to 82 percent in 1993 but had increased to 83 percent by 1997. Offer rates significantly changed between 1988 and 1997. In 1988, 82 percent of workers reported that they were eligible for health insurance through their employer. By 1993, the percentage of eligible workers declined to 74 percent, and it has only slightly increased since then to 75 percent in 1997. In 1997, 40.6 million American workers did not have health insurance through their own job. Forty-five percent of the workers without coverage were employed at a firm where the employer did not provide health insurance to any workers. Thirty-three percent of the workers without coverage were offered coverage but declined it. Twenty-two percent of the workers without coverage were employed in a firm that offered health insurance to some of its workers, but certain workers were not eligible for the health plan. The 13.7 million workers who were offered coverage but declined it gave a number of reasons for doing so. In the majority of cases (61 percent), the worker was covered by another health plan. Of the remainder, 20 percent reported that health insurance was just too costly. Overall, 41 percent of the 40.6 million workers who were not participating in an employment-based health plan through their own employer had coverage through a spouse. However, 42 percent of the 40.6 million workers who declined their employers' health plan or who were not offered health insurance from their employer were uninsured.

Death makes news: the social impact of disease on newspaper coverage.

UNLABELLED: This paper is an integrated analysis of newspaper coverage, epidemiological rates, and recent social history of six prominent diseases. HYPOTHESES: Newspaper coverage of a disease has three developmental stages (emergence, maturation, and decline & death). Trends in newspaper coverage of a disease reflect trends in its mortality, prevalence, and incidence. Magnitudes of newspaper coverage of diseases reflect their differential mortality rates. DATA: Using the LEXIS-NEXIS news archive for major U.S. newspapers, we retrieve articles about cancer, heart disease, AIDS, diabetes, Alzheimer disease, and arthritis for the period 1977-1997. We also obtain mortality, prevalence, and incidence trends for the six diseases. RESULTS: During the two decades, newspaper coverage emerges for AIDS and Alzheimer disease and is in the mature stage for the other diseases; declines begin for heart disease and AIDS. Trends in news coverage closely parallel mortality trends, and less consistently prevalence and incidence trends. Sharp downturns and upturns in mortality are mirrored in news volume. High-mortality diseases prompt both the most news coverage and the largest proportions of articles with death topics. CONCLUSION: Newspaper coverage of diseases is responsive to their mortality levels and trends.

State medicaid coverage for tobacco-dependence treatments--United States, 1998 and 2000.

The Guide to Community Preventive Services recommends reducing the cost of tobacco-dependence treatments because these interventions increase both the use of treatment by smokers during attempts to stop smoking and the number of smokers who actually stop. The Public Health Service (PHS) Clinical Practice Guideline supports insurance coverage for tobacco-dependence treatment (i.e., individual, group, and telephone counseling, and Food and Drug Administration-approved pharmacotherapy. One of the 2010 national health objectives is to provide coverage in the 50 states and District of Columbia (DC) for nicotine-dependence treatment by Medicaid (objective 27.8b). In 2000, approximately 32 million low-income persons in the United States received their health insurance coverage through the federal-state Medicaid program; approximately 11.5 million (36%) of these persons smoked (CDC, unpublished data, 2000). Medicaid recipients have approximately 50% greater smoking prevalence than the overall U.S. population. To assess the amount and type of coverage for tobacco dependence offered by Medicaid, the Center for Health and Public Policy Studies at the University of California, Berkeley, conducted state surveys in 1998 and 2000. In 1998, 24 states and DC offered some coverage for tobacco-dependence treatment; in 2000, nine started offering some coverage. In 1998 and 2000, one state offered coverage for all the counseling and pharmacotherapy treatments recommended by PHS. These findings indicate that states can reduce smoking prevalence among Medicaid recipients by implementing more extensive Medicaid coverage for treatment of tobacco dependence.

National, state, and urban area vaccination coverage levels among children aged 19-35 months--United States, 2000.

Since the early 1970s, childhood vaccination has prevented millions of illnesses and tens of thousands of deaths. For these health benefits to continue, high levels of vaccination coverage must be attained for each new birth cohort and must be monitored to ensure protection from disease, to characterize undervaccinated populations, and to evaluate effortsto increase coverage. The National Immunization Survey (NIS) provides ongoing national estimates of vaccination coverage among preschool-aged children for the 50 states and 28 selected urban areas. For this report, NIS data collected during 2000 were compared with 1999 data; findings indicate that, during 2000, significant increases were reported on the national level of vaccination coverage with varicella and hepatitis B, and small but statistically significant decreases were reported in coverage with diphtheria, and tetanus toxoid, and pertussis vaccine. Coverage with poliovirus vaccine, Haemophilus influenzae type b vaccine, and measles-mumps-rubella vaccine were not significantly different from 1999. As in previous years, coverage varied among states. To maximize coverage among preschool-aged children, vaccination providers should continue to apply such strategies as reminders and recalls.

Minority Response to Health Insurance Coverage for Mental Health Services.

BACKGROUND: To promote access to mental health services, policy makers have focused on expanding the availability of insurance and the generosity of mental health benefits. Ethnic minority populations are high priority targets for outreach. However, among persons with private insurance, minorities are less likely than whites to seek outpatient mental health treatment. Among those with Medicaid coverage, minorities continue to be less likely than whites to use services. AIMS OF THE STUDY: The present study sought to determine if public insurance is as effective in promoting outpatient mental healthtreatment as private coverage for ethnic minority groups. METHODS: The analysis uses data from the 1987 National Medical Expenditure Survey to model mental health expenditures as a function of minority status and private insurance coverage. An interaction term between the two highlights any differences in response to private and public insurance coverage. The analysis uses a two stage least squares method to account for endogeneity of insurance coverage in the model. RESULTS: Minorities are less responsive to private insurance than whites in two ways. First, minorities are less responsive to private insurance than to public insurance whereas whites do not show this difference. Second, minorities are less responsive to private insurance than whites are to private insurance. DISCUSSION: Results suggest that there is a difference in the effectiveness of public and private health insurance to encourage use of mental health services. Among minorities but not among whites, those with private coverage used fewer mental health services than those with public coverage. Minorities were not only less responsive to private insurance than public insurance, but among those who were privately insured, minorities used fewer mental health services than whites. These results imply that insurance may not be as effective a mechanism as hoped to encourage self-initiated treatment seeking particularly among minority and other low income populations. IMPLICATIONS FOR HEALTH CARE PROVISION AND USE: These results suggest that increasing private insurance coverage to minority populations will not eliminate racial and ethnic gaps in professional help-seeking for outpatient mental health care. Although the total number of people receiving treatment might increase, these results suggest that whites would seek care in greater numbers than minorities and the size of the minority-white differential might grow. IMPLICATIONS FOR FURTHER RESEARCH: Areas for further research include the impacts of alternative definitions of mental health services, the dynamics of the substitution of inpatient for outpatient mental health care, elucidation of nonfinancial barriers to care for minorities, and determinants of timely help-seeking among minorities.

Parental confidence in measles, mumps and rubella vaccine: evidence from vaccine coverage and attitudinal surveys.

BACKGROUND: The measles, mumps and rubella (MMR) vaccine has been the focus of considerable adverse publicity in recent years. AIM: To describe recent trends in parental attitudes to, and coverage of, MMR vaccine. DESIGN OF STUDY: Routine surveillance of vaccine coverage and cross-sectional surveys of parental attitudes. SETTING: All health authorities in England (vaccine coverage) and 132 enumeration districts in England (attitude survey). METHOD: Quarterly MMR vaccine coverage for all resident children in England at two years of age was requested from computerised child health information systems. Data was also obtained from 26 English health authorities/trusts on MMR coverage at 16 months of age. The proportion of mothers who believed that MMR vaccine was safe or carried only a slight risk, and the proportion who intended to fully vaccinate any future children, was obtained from biannual interviews with a national representative sample of over 1000 mothers of children under three years of age. RESULTS: Vaccine coverage at two years of age fell 8.6% (95% confidence interval [CI] = 8.4 to 8.8) between April and June 1995 and between April and June 2001. In September 2001, 67% of mothers reported that the MMR vaccine was safe or carried only a slight risk and 92% of mothers agreed with the statement: 'If I had another child in the future I would have them fully immunised against all childhood diseases'. CONCLUSIONS: Despite considerable adverse publicity, the fall in MMR coverage has been relatively small, mothers' attitudes to MMR remain positive, and most continue to seek advice on immunisation from health professionals. As the vast majority of mothers are willing to have future children fully immunised, we believe that health professionals should be able to use the available scientific evidence to help to maintain MMR coverage.

Changing the method for calculating quarters of coverage: the impact on workers' insured status.

The 1977 Social Security Amendments specified that, beginning in 1978, a worker would be credited with one quarter of coverage for a designated amount of annual earnings. For 1978, a worker received one quarter of coverage (up to a total of four) for each $250 in annual earnings from employment or self-employment. Before 1978, a worker who was paid $50 in wages in a calendar quarter was credited with a quarter of coverage. A person who had $400 or more in self-employment income in a year was credited with four quarters of coverage. Some workers received more quarters of coverage under the new provisions than they would have under the old, and other workers received less. Since a worker's receipt of benefits depends on his or her insured status, which is based on quarters of coverage, this change can affect a worker's eligibility for benefits. This study indicates that if $250 in annual earnings had been required for one quarter of coverage in 1977, more than 2.1 million workers would have had a change in their insured status for disabled worker benefits, and about 700,000 workers would have had a change in their insured status for survivor benefits. Those whose insured status was affected were most likely to have had marginal earnings records--for example, they had four to seven quarters of coverage when six were needed. (This effect was expected when the legislation was passed.) This article examines those whose eligibility for benefits was most likely to have been affected.

Improving vaccination coverage: the experience of the Expanded Programme on Immunization in Vanuatu.

This paper looks at the success of measures adopted to improve vaccination coverage of infants in the Republic of Vanuatu. In 1982 the Department of Health introduced an Expanded Programme on Immunization (EPI). Since the republic has over 80 inhabited islands, a scattered population, rough terrain and a lack of transport and communications infrastructure, achieving a high vaccination coverage rate proved difficult. Coverage of infants remained low until 1987. From that year onwards various strategies were employed to increase coverage, including 1) adopting the WHO-recommended diphtheria-pertussis-tetanus (DPT) and oral polio vaccine (OPV) vaccination schedule (6, 10 and 14 weeks) instead of the former schedule (3, 6 and 9 months); 2) improving the training, support and supervision of staff delivering maternal and child health (MCH) services; and 3) improving community involvement through social mobilization activities in areas of low coverage. Data on vaccination coverage of infants for the period 1984 to 1990 were compared. Over this period coverage of infants with 3 doses of DPT rose from 29% to 76%, with 3 doses of OPV from 29% to 78%, and with measles vaccine from 19% to 66%. These dramatic improvements have largely occurred since 1987. The results demonstrate the success of the measures adopted, and the experience of Vanuatu offers lessons in improving vaccination coverage for other countries in the region.
