Delivering breast and cervical cancer screening services to underserved women: Part II. Implications for policy.

Many breast and cervical cancer screening (BCCS) programs for underserved women employ strategies to increase the use of preventive services. In Phase I of a two-phase study, strategies were identified and assessed. In Phase II, we further assess strategies previously identified and comment on policy implications. Site visits were conducted at BCCS programs that had used one successful strategy identified during Phase I, provided services to underserved women, and were located in different geographic regions. The federally funded National Breast and Cervical Cancer Early Detection Programs (NBCCEDP) were also considered for site visits. Interviews were completed and available data were reviewed. A descriptive and qualitative analysis was completed. Programs visited were found to be increasing the use of BCCS services for the defined target populations. Some programs focused on outreach and recruitment. Other programs focused on clinical preventive services with little emphasis on outreach and recruitment. Management information systems were used by most programs. We found that there continues to be a large number of women not receiving BCCS services. Some programs have had to limit outreach and recruitment because the clinical preventive services offered are at capacity. Programs need to have a balanced approach to providing services from the outset. Existing programs may need to establish partnerships to provide comprehensive BCCS services to underserved women. Because the unmet need (women who have not received BCCS services) exceeds available clinical preventive services, it is a challenge to know how to best use available resources.

Antibiotic resistance monitoring in bacteria of animal origin: analysis of national monitoring programmes.

Methods of antibiotic resistance monitoring of bacteria from animals in 12 European countries were surveyed in 1998. Most laboratories used disk diffusion methods, usually expressing results qualitatively, although a few also expressed the results either as MICs or zone diameters. The number of antibiotics used ranged from 5 to 37 (mean 15) and the most common antibacterials were streptomycin, gentamicin, neomycin, ampicillin, tetracyclines, chloramphenicol and sulphonamides. Salmonellae were monitored by most centres but few-tested campylobacter regularly. Escherichia coli from a wide range of animal species were tested in nine countries. Enterococci were tested on a limited ad hoc basis in six countries. Staphylococci, streptococci and pasteurellae were also frequently monitored but the number of isolates tested showed wide variation. Overall the presentation of the results differed, but most programmes used disk diffusion, control strains and monitored similar bacteria. Thus, it may be possible to harmonise monitoring programmes within the EU.

Community health workers and primary health care in Honduras.

Community participation and utilization of community health workers (CHWs) are essential components of the primary health care model. The success of CHWs is dependent on their training and subsequent community support. Community-prepared nurses are ideal CHW educators. A training program for CHWs was implemented in Honduras emphasizing the principles of adult learning and problem-based learning. Following a 4-month program of training a primary health care clinic was opened and managed by CHWs for a population over 10,000. Approximately 80% of local health problems were managed by the CHWs proving that well-trained CHWs can have a significant impact on the delivery of health care.

Data-based planning for educational interventions through hypertension control programs for urban and rural populations in Maryland.

As part of a statewide effort to coordinate existing resources for high blood pressure (HBP) control, a public health HPB control program was planned and implemented in two high-risk communities in Maryland. The selection of the two communities was based on epidemiologic data. The planning of the educational intervention program in these communities (urban and rural) was guided by organizational theory and health education principles. The framework for development, implementation, and evaluation of the program utilizes an educational assessment model which identified factors that predispose, reinforce, and enable individual persons to practice positive health behavior. Multiple data sources were used in assessing the extent of the problem and relevant approaches in the development of the coordinated HPB control program. These include statewide vital statistics and a random statewide household survey to assess the prevalence rates of awareness, treatment, and control of HPB. To supplement these data, telephone surveys were carried out in the two communities to assess knowledge, beliefs, and practices related to HPB control. Medical record reviews provided baseline information on appointment keeping behavior and BP correlates of hypertensive patients. The planning and implementation of the program was carried out under the direction of representatives of the health care systems, community leaders, and residents, and representatives of communitywide organizations involved in HPB control.

Widespread HIV counseling and testing linked to a community-based tuberculosis control program in a high-risk population.

The aim of the work reported here was to evaluate community-wide screening for HIV infection that was linked to a tuberculosis control program in a population at high risk for both infections. Between May 1990 and August 1992, adults in Cité Soleil, Haiti, were recruited by community health workers at their homes and in clinics for individual, clinic-based counseling and testing for HIV and tuberculosis. All of the screened subjects were offered post-test HIV counseling. Those with active tuberculosis received treatment, while those with latent tuberculosis and HIV infection were offered an opportunity to participate in a trial of antituberculosis chemoprophylaxis. The 10,611 individuals screened for HIV represented 10.0% of the adult population in Cité Soleil. HIV infection was detected in 1,629 (15.4%) and active tuberculosis in 242 (2.3%). Latent M. tuberculosis infection was found in 4,800 (67.5%) of 7,309 community residents who completed tuberculosis screening, 781 (16.3%) of whom were coinfected with HIV. The high prevalence of HIV infection found in this screened population, as compared to other groups undergoing HIV screening in the same community, suggests that people at high risk for HIV infection selectively sought or accepted tuberculosis clinic screening. Also, many people with active tuberculosis were identified earlier in the course of their disease than they would have been in the absence of a screening program. Overall, the results indicate that community-based screening for HIV infection within a tuberculosis control program can result in effective targeting of screening for both infections.

Foot problems associated with older patients. A focused podogeriatric study.

The authors report on a 3-year prospective program that included foot-health education and an initial assessment of foot problems in an older population. The program represents a cooperative effort by the Philadelphia Corporation for Aging and the Pennsylvania College of Podiatric Medicine to enhance the quality of life of older citizens. The results show that foot problems are prevalent among older patients. The program also refined a protocol that can be applied in other settings.

Reversal of female sterilisation: outcome of 210 referrals.

AIMS: To determine the outcome of request for reversal of sterilisation and to compare demographic and social factors of women who subsequently withdrew their request with those who proceeded with the reversal assessment and operation. METHODS: Information relating to the sterilisation and regret intervals were sought from 210 women. Demographic and social factors were recorded and the outcome of the reversal request determined. Patients who withdrew or were deferred/declined were compared on relevant factors with the group who proceeded to, or are still planning, the reversal operation. RESULTS: Ninety-two (44%) withdrew before or during the assessment phase. Another 13 withdrew after laparoscopy identified a poor prognosis. Three declared their intention not to conceive after they underwent the reversal operation. To date, 83 have had surgery with the cumulative intrauterine pregnancy rate at 1, 2 and 3 years being 0.46, 0.62 and 0.78 respectively. In comparing those women who proceeded and withdrew, there were no differences in mean age at referral, age at sterilisation, the number of living children nor marital status. The regret interval prior to referral was significantly longer in the women who proceeded (27.9 and 19.5 months respectively, p = 0.03). Those who were highly motivated in their reversal request were also more likely to proceed (p = 0.003). CONCLUSIONS: There is a large dropout rate of women who seek a reversal of sterilisation. Women who regret sterilisation may have sought sterilisation as a solution to problems that were psychosocial rather than contraceptive in nature. We stress the importance of counselling for both sterilisation and its reversal, since in the latter many developmental personality and relationship problems remain unresolved.

Evaluation of a bayesian pharmacokinetic program for phenytoin concentration predictions in outpatient population.

The present work evaluates the performances of a Bayesian program (PKS) for phenytoin concentration predictions in an outpatient population. The retrospective study involved 19 epileptic adults receiving oral phenytoin. The program was used to predict estimated serum concentrations from 0, 1, 2 or 3 feedback concentrations. Measurements of prediction bias (ME) decreased as soon as one steady-state concentration (Css) was used for estimations. Precision (MAE) was significantly improved with 1 Css and was even better and stable with 2 and 3 Css. Likewise, RMSE (composite of bias and precision) regularly decreased when the number of Css used increased. On a clinical way, 12% of the estimations were unacceptable (prediction error > 5 mg/l) with 1 Css and less than 3% with 2 or 3 Css. This number of rejected estimations increased to 45% when no feedback concentration was used. Besides, the program was able to predict important rises of serum levels in spite of relative low increase of the dose when 1 Css at least was known. Thus, the phenytoin dosing program has acceptable performances when at least 1 Css is known, and represents a potential tool to assist the clinician in the particular condition of outpatient population.

VISION USA--optometry's national charity program.

BACKGROUND: There are an estimated 18 million uninsured working Americans and their families who are unable to afford the cost of eye care. These individuals often fall between the cracks of government and private health care assistance. Members of the American Optometric Association have developed the VISION USA program to provide free eye care to those who might otherwise not receive it. METHODS: Nearly 8,000 doctors of optometry nationwide have volunteered to provide free eye examinations in their offices for VISION USA patients. Patients are screened for eligibility and matched to the nearest available participating doctor using a computerized ZIP code matching system. Examinations are usually provided each year during March in observance of Save Your Vision Week. RESULTS: In the first three years of the program, services have been provided to over 115,000 individuals. For over 21 percent of the patients seen, this was their first eye examination ever. More than 86 percent of the patients had one or more vision problems. More than 70 percent were given new or updated prescriptions. CONCLUSION: The VISION USA program is helping to meet a significant unmet need for eye care which exists within a segment of the American population. The program is an outstanding example of the willingness of doctors of optometry to give back to their communities, and to those in need, some of what they have gained from the practice of their profession.

Childlessness, subfertility, and infertility in Tanzania.

This study examines the trends and variations in childlessness, subfertility, and infertility in Tanzania according to data from the 1973 National Demographic Survey and the 1991-92 Demographic and Health Survey. Between the surveys, the proportion of women older than 30 who were childless was found to have declined more than 60 percent, and the proportion with an open birth interval extending for longer than five years was reduced by 40 to 50 percent in each standard five-year age group from 20 to 39. Within Tanzania, both childlessness and infertility are higher among urban than rural residents, and a substantial range prevails across eight rural zones. Finally, evidence suggests that the decline in impaired fertility has been followed by an increase in the total fertility rate. The difficulties of implementing population policies that aim simultaneously to control population growth and to improve women's health are discussed.

Multiple von Neumann computers: an evolutionary approach to functional emergence.

A novel system composed of multiple von Neumann computers and an appropriate problem environment is proposed and simulated. Each computer has a memory to store the machine instruction program, and when a program is executed, a series of machine codes in the memory is sequentially decoded, leading to register operations in the central processing unit (CPU). By means of these operations, the computer not only can handle its generally used registers but also can read and write the environmental database. Simulation is driven by genetic algorithms (GAs) performed on the population of program memories. Mutation and crossover create program diversity in the memory, and selection facilitates the reproduction of appropriate programs. Through these evolutionary operations, advantageous combinations of machine codes are created and fixed in the population one by one, and the higher function, which enables the computer to calculate an appropriate number from the environment, finally emerges in the program memory. In the latter half of the article, the performance of GAs on this system is studied. Under different sets of parameters, the evolutionary speed, which is determined by the time until the domination of the final program, is examined and the conditions for faster evolution are clarified. At an intermediate mutation rate and at an intermediate population size, crossover helps create novel advantageous sets of machine codes and evidently accelerates optimization by GAs.

Improved birth outcomes associated with enhanced Medicaid prenatal care in drug-using women infected with the human immunodeficiency virus.

OBJECTIVE: To evaluate the effectiveness of an intervention designed to enhance Medicaid prenatal care in improving birth outcomes of drug-using women infected with the human immunodeficiency virus (HIV). METHODS: Medicaid and vital statistics records were linked for 353 HIV-infected drug-using women delivering in 1993 and 1994 while enrolled in New York State Medicaid. Of these, 68% were treated by providers participating in the Prenatal Care Assistance Program, designed to provide case management, improved continuity, referral services, and behavioral risk reduction counseling. In a series of logistic models, we estimated adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of low birth weight (less than 2500 g) and preterm delivery (before 37 weeks), comparing women using and not using the program. RESULTS: Women using the Prenatal Care Assistance Program were significantly less likely, after adjustments were made for maternal characteristics, to have low birth weight infants and preterm deliveries (OR 0.52, 95% CI 0.31, 0.89; and OR 0.57, 95% CI 0.34, 0.97, respectively). Adding measures of greater adequacy and continuity of prenatal care to the models explained just over 20% of the Prenatal Care Assistance Program's protective effect. The addition of maternal high-risk behavior, HIV-focused care, and drug use treatment variables altered program effect estimates less profoundly (together accounting for 4 and 9% of the program's protection against low birth weight and preterm delivery, respectively). CONCLUSION: The Prenatal Care Assistance Program appeared to be successful in reducing the incidence of low birth weight and preterm delivery in this high-risk population. The program's success can be attributed, in part, to increased adequacy and continuity of prenatal care and, to a lesser extent, to more frequent receipt of special services and reduced maternal high-risk behaviors.

Exposure to a rural population in a rural residency training program.

Previous reports of rural training programs conducted by medical schools have not examined the relationship between the population residing in an area and the population receiving medical services through the clinical training program. In the present study rural household survey data were compared with patient encounter data from a rural ambulatory cliinic engaged in training Family Practice residents from the Texas Tech University School of Medicine. Clinic patients were found to resemble the rural population subgroup that visits a physician at least once a year. Wide variations in individual clinical experiences were observed when health problems and conditions encountered by residents were compared with problems encountered in the clinic as a whole. In light of current national efforts to increase medical care access in unserved and underserved populations, the demographic findings raise questions concerning appropriate patient exposure goals in clinical training programs.
