Methodological issues in evaluating expanded Medicaid coverage for pregnant women.

In a recent effort to lower the US infant mortality rate, Congress has expanded the Medicaid coverage options that states may offer pregnant women. Careful evaluation of changes in perinatal outcome associated with this expanded coverage is needed. The linkage of Medicaid enrollment files of mothers and infants to birth, death, and fetal death certificates is an initial step in assessing the effectiveness that Medicaid coverage expansions have had on pregnancy outcome. Creation of such a database for Tennessee for 1984-1987 revealed that complete information on mother, delivery, and child is available for only three quarters of Medicaid-reimbursed births. Furthermore, Medicaid-reimbursed births that had all three data components had different characteristics and lower mortality rates than did births with missing elements. Those persons seeking to evaluate expanded Medicaid coverage for pregnant women need to be aware that consideration of only those births for whom there is information on mother, delivery, and child may lead to serious underascertainment of fetal, perinatal, and neonatal mortality rates.

Increasing the coverage of vaccination against influenza by general practitioners.

BACKGROUND: To increase the coverage of influenza vaccination in groups of patients at risk, an experiment was conducted in 1993, aimed at logistic support of general practitioners (GPs). METHODS: Support was given to 56 GPs with 133,000 patients to select and invite patients at risk. The coverage of vaccination as a result of this experiment has been compared with the results obtained from the Health Interview Survey, in The Netherlands as a total. RESULTS About 15,000 patients at risk were invited for vaccination, of whom 75.5 per cent were vaccinated. In The Netherlands as a total, the coverage of patients at risk was 43 per cent. CONCLUSION: Because the selection and invitation of patients at risk is still a problem for many GPs, owing to the lack of computerization, logistic support can ease these tasks and thus help increase the coverage of vaccination against influenza in groups of patients at risk.

Comparison of seven- and five-day physical therapy coverage in patients with acute orthopedic disorders.

This study evaluated the efficacy of seven- versus five-day physical therapy coverage in an acute care hospital setting by monitoring percentage of consecutive treatments, mean number of treatments per patient, and lengths of hospital stay (LOS) for 482 patients with acute orthopedic disorders. The Experimental Group (n = 276) received seven-day coverage; the Comparison Group (n = 206) received five-day coverage for four months. Results were analyzed for the group as a whole and by diagnostic categories. Experimental Group subjects received a higher percentage of consecutive treatments than the Comparison Group subjects (72% vs 42%). No difference was found between the groups for mean number of physical therapy treatments received per patient. The LOS was neither significantly different between the two groups as a whole nor for 9 of the 11 diagnostic categories. The results imply that providing consecutive physical therapy treatments through seven-day coverage without increasing the number of physical therapy treatments will not reduce the LOS for patients with acute orthopedic disorders.

A descriptive study of the decline in cervical screening coverage rates in the North East and Yorkshire and the Humber regions of the UK from 1995 to 2005.

Since the mid-1990s, there has been a steady decline in coverage rates for cervical screening in the target age group (25-64 years) across England. This article describes the rate of decline from 1995 to 2005 in the old health authority areas of the North East and the Yorkshire and the Humber (NEYH) regions in relation to age group, deprivation, ethnicity and religion. The results show that the rate of decline is faster in these northern regions than that in England as a whole, with a very strong correlation between age and rate of change of coverage rates. Younger age groups experience the fastest rate of decline, and those over 55 years show an increase in coverage rates. There is an association between the deprivation of the old health authority areas and the rate of change of coverage rates, with weaker evidence that areas with high proportions of Black or Mixed ethnicity may have a faster decline. However, the rate of decline is not associated with other ethnic groups or religions. Therefore, interventions could be targeted at younger women and those who live in deprived areas to prevent the widening of inequalities.

Mother-to-child HIV transmission in resource poor settings: how to improve coverage?

OBJECTIVES: To review coverage of the current nevirapine prevention model in Coast Provincial General Hospital (CPGH) in Mombasa, Kenya, and to reflect on alternative models to reduce mother-to-child transmission (MTCT) of HIV. METHODS: At the antenatal clinic, health information is provided, followed by pre-test HIV voluntary counselling and testing (VCT). Because many women deliver at home, HIV-infected women are provided with a tablet of 200 mg nevirapine for themselves, and with 0.6 ml (6 mg) nevirapine in a luer lock syringe for the baby. Data on coverage are provided from antenatal records and delivery registers. RESULTS: Out of 3564 first-visit pregnant women receiving health education, 2516 were counselled (71%) and 2483 were tested (97%); 348 were HIV positive (14%), and 106 women took nevirapine in labour, resulting in an overall coverage rate of 20%. In the same period, approximately 6000 women gave birth in CPGH, of whom 21% had attended a facility with VCT services. Assuming an overall HIV prevalence of 14%, 840 mother-infant pairs could have received a preventative intervention with a hospital policy of antepartum as well as intrapartum testing and treatment in place. CONCLUSION: The coverage of perinatal MTCT was low as a result of a variety of programme elements requiring urgent improvement at different levels. Alternative models, including intrapartum testing, should be considered as a safety net for women without access to VCT before delivery, and recommendations for nevirapine should be considered in the light of home deliveries.

Reduced wound contraction after grafting of full-thickness burns with a collagen and chondroitin-6-sulfate (GAG) dermal skin substitute and coverage with biobrane.

Full-thickness burns destroy both the epidermal and dermal tissues of the skin. This study evaluates a collagen and chondroitin-6-sulfate dermal skin substitute (graft) that was applied to excised full-thickness burns and covered with Biobrane. Experimental conditions included: (a) no burn, subcutaneous implantation of the graft; (b) burn, excision, graft, coverage with Biobrane and bandages; (c) burn, excision, no graft, coverage with Biobrane and bandages; (d) burn only. forty-one days post-surgery, subcutaneous implantation (N = 3) of the graft caused no detectable contraction or necrosis of the overlying skin, whereas all burn wounds contracted. Measurements of wounds (percentage of original wound size) showed statistically significant differences between the following treatments; (a) graft plus Biobrane (N = 10), 34%; (b) no graft plus Biobrane (N = 9), 25%; (c) untreated burns (N = 6), 16%. Semi-quantitative evaluation of time to healing indicated by spontaneous detachment of Biobrane from wounds showed that grafted, excised wounds healed in an average of 2.7 weeks, while ungrafted, excised wounds required an average of 4.3 weeks to heal. Histological appearance of healed wounds after grafting and coverage with Biobrane resembles undamaged skin without epidermal adnexal structures. Excision of full-thickness burn eschar, followed by grafting with a collagen and chondroitin-6-sulfate dermal skin substitute and coverage with Biobrane provides reduced wound contraction within a six-week period of observation compared to non-excised wounds. Both more rapid and more complete wound healing took place compared to excised wounds that were not grafted.

Free flaps as flow-through vascular conduits for simultaneous coverage and revascularization of the hand or digit.

In complex extremity injuries, which include volar skin loss and ischemic digits, simultaneous coverage and revascularization are required. In this series of 12 patients, free-tissue transfers were utilized to provide both soft tissue coverage and a flow-through arterial conduit for revascularization. Eleven cases involved the hand or digits, and one case involved the great toe. Six cases were performed for acute ischemia associated with traumatic soft-tissue loss. The remaining six flaps were utilized to lengthen contracted vascular pedicles and provide vascularized soft-tissue coverage during reconstruction of severe hand and foot contractures. Nine temporoparietal fascia free flaps were used for hand or digit revascularization. Two fillet flaps were created, one from a nonreplantable foot and another from an isolated index amputation. The distal end of the axial artery of the flap was anastomosed to a digital artery to restore circulation. Fascial flaps were covered with full-thickness skin grafts. Primary wound healing was achieved in all patients. There were no flap losses or other complications. All the distal parts were revascularized adequately by the axial arteries of the flaps, and functional recovery was good. In this technique, the flap satisfied the need for both coverage and revascularization. Vein grafts were not needed. This series further describes the utility of flow-through flaps in the revascularization of digits.

Gluteal perforator flaps for coverage of pressure sores at various locations.

Flap coverage is essential for successful treatment of pressure sores, and musculocutaneous flaps have been preferred universally. Development of perforator flaps supplied by musculocutaneous perforators has allowed reconstructive surgeons to harvest flaps without including muscles. Perforator flaps have enhanced the possibility of donor sites because a flap can be supplied by any musculocutaneous perforator, and donor-site morbidity is also reduced. Between November of 1998 and June of 2002, the authors used 35 gluteal perforator flaps in 32 consecutive patients for coverage of pressure sores located at sacral (n = 22), ischial (n = 7), and trochanteric (n = 6) regions. The mean age of the patients was 53.1 years (range, 5 to 87 years), and there were 16 male and 16 female patients. All flaps in this series were supplied by musculocutaneous arteries arising from gluteal muscles. Patients were followed up for a mean period of 13.6 months. Wound dehiscence was observed in two patients and treated by secondary closure. Three patients died during the follow-up period. All flaps survived except one that had undergone total necrosis, and only one recurrence was noted during the follow-up period. Gluteal perforator flaps are safe and reliable options for coverage of pressure sores located at different locations. Freedom in flap design and low donor-site morbidity make gluteal perforator flaps an excellent choice for pressure sore coverage.

Acetabular coverage: three-dimensional anatomy and radiographic evaluation.

The three-dimensional relationship between acetabulum and femoral head, known as coverage, was evaluated radiographically using a modified inlet view of the pelvis. The relationship of the anterior edge, the center of the femoral head, and the posterior edge of the acetabulum is a straight line (180 degrees) in normal coverage but less in dysplastic hips. This radiographic method provides anatomical information concerning anterior and posterior coverage. Evaluation of 26 hips delineated problems, including possible danger of anterolateral rotation of the acetabulum in the face of posterior deficiency and inadequacy of posterior coverage after Chiari osteotomy.

Adherence to chronic cardiovascular therapies: persistence over the years and dose coverage.

AIM: To evaluate adherence to chronic cardiovascular drug treatments, in terms of long-term persistence and dose coverage. METHODS: General practice prescription data of antihypertensives, lipid-lowering agents, oral hypoglycaemic agents and nitrates were collected over a 5-year period (1998-2002) in a Northern Italian district (Ravenna, 350,000 inhabitants). We selected subjects (>40 years) receiving at least one prescription of the above drugs in December 1999. For each patient, we documented the regimen at the time of selection and evaluated adherence to treatment during the following 3 years in terms of persistence (at least one prescription per year) and daily coverage (recipients of an amount of medication consistent with daily treatment). RESULTS: Fewer than 10% of the 32 068 selected subjects were naive to treatment. Antihypertensives were the most represented therapeutic category. Among patients already on treatment in December 1999, persistence was virtually complete, whereas >40% of naive patients withdrew within 1 year, except for nitrates. The rates of coverage were always much lower than the corresponding values of persistence. Coverage was significantly higher in older patients (chi(2) for trend 69.41; P < 0.001), males (odds ratio 1.30; 95% confidence interval 1.25, 1.36) and users receiving more than one therapeutic category. CONCLUSIONS: Lack of adherence to chronic cardiovascular treatments represents an important matter of concern: although most people continued treatment over the years, less than 50% received an amount of drugs consistent with daily treatment, thus jeopardizing the proved beneficial effects of available medications.

Mapping the environmental coverage of the INDEPTH demographic surveillance system network in rural Africa.

OBJECTIVES: The INDEPTH DSS network was founded in 1998 to provide an international network of field sites for continuous demographic evaluation of populations and their health. Results from the network have been used to derive estimates of mortality, morbidity and health equity. Spatial extrapolation and logical summaries of these findings are dependent on the network covering a representative sample of the environments in a region and their interrelationships being known. Here, we investigate how comprehensive is the coverage of the network of rural DSS sites in Africa in terms of the range of ecological zones found across the continent. METHODS: We used satellite imagery to define an environmental signature for each INDEPTH DSS site, and then calculate Euclidean distances from these signatures to the environmental signatures of every image pixel across Africa. These distances were then mapped and a gridded population surface used to mask uninhabited areas to illustrate the extent of the environmental coverage of the INDEPTH network. Environmental similarities between DSS sites were also calculated, hierarchically clustered and visualized as a dendrogram to examine between site relationships. Finally, an ecozonation of Africa was used to analyse the per-ecozone environmental similarity of the INDEPTH DSS network. RESULTS AND CONCLUSIONS: The current INDEPTH DSS network in Africa spans all the major environmental zones, but within these zones the environmental coverage of the network varies. These variations were mapped by ecozone. These maps provide valuable information in determining the confidence with which relationships derived from rural INDEPTH DSS sites can be extended to other areas. The results also indicate suites of sites that form environmentally cohesive groups and from which data can be logically summarized. Finally, the results highlight areas where the location of new INDEPTH DSS sites would increase significantly the environmental coverage of the network.

The initial coverage and impact of the pneumococcal and influenza vaccination program for at-risk indigenous adults in Far North Queensland.

OBJECTIVES: To describe the initial coverage and impact of a pneumococcal and influenza vaccination program for at-risk Indigenous adults in Far North Queensland that formally commenced in 1996. DESIGN: Ascertainment of vaccine coverages, and prospective laboratory surveillance of invasive pneumococcal disease occurring in Indigenous adults in the region. MAIN OUTCOME MEASURES: Coverages of the first doses of both vaccines administered since 1995, and the incidence of invasive pneumococcal disease in Indigenous adults in the region between 1993-2000. RESULTS: Most (96% and 73%) of the Indigenous adults > or = 50 years of age received influenza and pneumococcal vaccines, respectively, for the first time between 1995-2000. Assuming that either 33% or 50% of Indigenous adults 15-49 years of age in Far North Queensland were eligible for vaccination, then either 109% or 72% of this population received influenza vaccine, and either 75% or 50% received pneumococcal vaccine, respectively, for the first time between 1995-2000. The incidence of vaccine-preventable invasive pneumococcal disease fell from 111 (95% confidence interval [CI] 77-154) cases per 100,000 per year in 1993/94 to 28 (95% CI 13-53) cases per 100,000 per year in 1999-2000 (p<0.05). CONCLUSION: Although there was a significant decline in the incidence of invasive pneumococcal disease, the vaccine coverages after five years of the program were suboptimal. Because of the difficulties in targeting the 15-49 years age group and because of unrecognised risk factors, we suggest that a universal Indigenous adult pneumococcal and influenza vaccination program should be considered.

Evaluation of immunisation coverage for aboriginal and Torres Strait Islander children using the Australian Childhood Immunisation Register.

OBJECTIVE: To estimate immunisation coverage for routinely administered vaccines among children using receipt of a particular Hib vaccine (PRP-OMP) as a proxy for Indigenous status. METHODS: Until May 2000, PRP-OMP was provided only for Indigenous children in all jurisdictions except the Northern Territory. In three one-year ACIR-derived birth cohorts, any child recorded on the ACIR as receiving one or more doses of PRP-OMP as the only Hib vaccine was presumed to be Aboriginal and Torres Strait Islander. Using this proxy, estimated numbers of Indigenous children were compared with Australian Bureau of Statistics estimates, and immunisation status for recommended vaccines was estimated at 12 and 24 months by jurisdiction and remoteness compared with children who received other Hib vaccines (presumed non-Indigenous). RESULTS: The numbers of Aboriginal and Torres Strait Islander children estimated using this 'proxy method' are approximately 42% of those estimated by the ABS. Immunisation coverage (among proxy Indigenous children) at 12 months (72-76%) and 24 months (64-73%) was considerably lower than others (90-94% and 81-88%, respectively). These children had significantly lower coverage when living in accessible areas than remote areas. CONCLUSIONS AND IMPLICATIONS: These data provide the first national measure of immunisation status and are likely to be a valid measure among those identified. Aboriginal and Torres Strait Islander immunisation coverage is 17% lower with the biggest gaps in urban areas, indicating the need for better quality data informing appropriate interventions.

The association between health insurance coverage and diabetes care; data from the 2000 Behavioral Risk Factor Surveillance System.

OBJECTIVE: To describe the association between type of health insurance coverage and the quality of care provided to individuals with diabetes in the United States. DATA SOURCE: The 2000 Behavioral Risk Factor Surveillance System. STUDY DESIGN: Our study cohort included individuals who reported a diagnosis of diabetes (n=11,647). We performed bivariate and multivariate logistic regression analyses by age greater or less than 65 years to examine the association of health insurance coverage with diabetes-specific quality of care measures, controlling for the effects of race/ethnicity, annual income, gender, education, and insulin use. PRINCIPAL FINDINGS: Most individuals with diabetes are covered by private insurance (39 percent) or Medicare (44 percent). Among persons under the age of 65 years, 11 percent were uninsured. The uninsured were more likely to be African American or Hispanic and report low incomes. The uninsured were less likely to report annual dilated eye exams, foot examinations, or hemoglobin A1c (HbA1c) tests and less likely to perform daily blood glucose monitoring than those with private health insurance. We found few differences in quality indicators between Medicare, Medicaid, or the Department of Veterans Affairs (VA) as compared with private insurance coverage. Persons who received care through the VA were more likely to report taking a diabetes education class and HbA1c testing than those covered by private insurance. CONCLUSIONS: Uninsured adults with diabetes are predominantly minority and low income and receive fewer preventive services than individuals with health insurance. Among the insured, different types of health insurance coverage appear to provide similar levels of care, except for higher rates of diabetes education and HbA1c testing at the VA.

Medicare Part D coverage and its influence on transplant patients' out-of-pocket prescription expenses.

Since Medicare is available for qualifying individuals because of age (65 years or greater), disability, or end-stage renal disease, many transplant recipients have Medicare coverage. Everyone who is entitled to Medicare will qualify to enroll in a Part D plan-a voluntary prescription drug coverage option offered by private insurance companies who meet the standards established by Medicare. The addition of Medicare Part D may help reduce out-of-pocket medication expenses for transplant recipients who have Medicare; however, the reality of utilizing Part D to maximize recipients' benefits is not simple, but rather complicated. The intricacies of Part D involve not only understanding premium costs and benefit stages, but formularies, and, particularly for transplant patients, deciphering how Medicare Part B immunosuppressant coverage influences Part D coverage. This article details significant information concerning Part D that transplant health care professionals should know in order to maximize patients' benefits and minimize their out-of-pocket medication expenses.

Cataract surgical coverage and outcome in the Tibet Autonomous Region of China.

BACKGROUND: A recently published, population based survey of the Tibet Autonomous Region (TAR) of China reported on low vision, blindness, and blinding conditions. This paper presents detailed findings from that survey regarding cataract, including prevalence, cataract surgical coverage, surgical outcome, and barriers to use of services. METHODS: The Tibet Eye Care Assessment (TECA) was a prevalence survey of people from randomly selected households from three of the seven provinces of the TAR (Lhoka, Nakchu, and Lingzhr), representing its three main environmental regions. The survey, conducted in 1999 and 2000, assessed visual acuity, cause of vision loss, and eye care services. RESULTS: Among the 15,900 people enumerated, 12,644 were examined (79.6%). Cataract prevalence was 5.2% and 13.8%, for the total population, and those over age 50, respectively. Cataract surgical coverage (vision <6/60) for people age 50 and older (85-90% of cataract blind) was 56% overall, 70% for men and 47% for women. The most common barriers to use of cataract surgical services were distance and cost. In the 216 eyes with cataract surgery, 60% were aphakic and 40% were pseudophakic. Pseudophakic surgery left 19% of eyes blind (<6/60) and an additional 20% of eyes with poor vision (6/24-6/60). Aphakic surgery left 24% of eyes blind and an additional 21% of eyes with poor vision. Even though more women remained blind than men, 28% versus 18% respectively, the different was not statistically significant (p = 0.25). CONCLUSIONS: Cataract surgical coverage was remarkably high despite the difficulty of providing services to such an isolated and sparse population. Cataract surgical outcome was poor for both aphakic and pseudophakic surgery. Two main priorities are improving cataract surgical quality and cataract surgical coverage, particularly for women.

Socioeconomic disparities in health care use: Does universal coverage reduce inequalities in health?

BACKGROUND: Despite enormous public sector expenditures, the effectiveness of universal coverage for health care in reducing socioeconomic disparities in health has received little attention. STUDY OBJECTIVE: s: To evaluate whether universal coverage for health care reduces socioeconomic disparities in health. DESIGN: Information on participants of the 1990 Nova Scotia Nutrition Survey was linked with eight years of administrative health services data and mortality. The authors first examined whether lower socioeconomic groups use more health services, as would be expected given their poorer health status. They then investigated to what extent differential use of health services modifies socioeconomic disparities in mortality. Finally, the authors evaluated health services use in the last years of life when health is poor regardless of a person's socioeconomic background. SETTING: The Canadian province of Nova Scotia, which provides universal health care coverage to all residents. PARTICIPANTS: 1816 non-institutionalised adults, aged 18-75 years, from a two stage cluster sample stratified by age, gender, and region. MAIN RESULTS: People with lower socioeconomic background used comparatively more family physician and hospital services, in such a way as to ameliorate the socioeconomic differences in mortality. In contrast, specialist services were comparatively underused by people in lower socioeconomic groups. In the last three years of life, use of specialist services was significantly higher in the highest income group. CONCLUSIONS: Universal coverage of family physician and hospital services ameliorate the socioeconomic differences in mortality. However, specialist services are underused in lower socioeconomic groups, bearing the potential to widen the socioeconomic gap in health.

Print media coverage of California's smokefree bar law.

OBJECTIVE: To assess the print media coverage of California's smokefree bar law in the state of California. DESIGN: Content analysis of newspaper, trade journal, and magazine items. SUBJECTS: Items regarding the smokefree bar law published seven months before and one year following the implementation of the smokefree bar law (June 1997 to December 1998). Items consisted of news articles (n = 446), opinion editorials (n = 31), editorials (n = 104), letters to the editor (n = 240), and cartoons (n = 10). MAIN OUTCOME MEASURES: Number and timing of publication of items, presence of tobacco industry arguments or public health arguments regarding law, positive, negative, and neutral views of opinion items published. RESULTS: 53% of items published concerning the smokefree bar law were news articles, 47% were opinion items. 45% of items regarding the smokefree bar law were published during the first month of implementation. The tobacco industry dominated coverage in most categories (economics, choice, enforcement, ventilation, legislation, individual quotes), except for categories public health used the most frequently (government role, tactics, organisational quotes). Anti-law editorials and letters to the editor were published more than pro-law editorials and letters. Region of the state, paper size, presence of local clean indoor air legislation, and voting on tobacco related ballot initiatives did not have an impact on the presence of opinion items. CONCLUSIONS: The tobacco industry succeeded in obtaining more coverage of the smokefree bar law, both in news items and opinion items. The tobacco industry used historical arguments of restricting freedom of choice and economic ramifications in fighting the smokefree bar law, while public health groups focused on the worker protection issue, and exposed tobacco industry tactics. Despite the skewed coverage, public health groups obtained adequate attention to their arguments to keep the law in effect.
