Bladder management in adult care homes. Review of a program in North Carolina.

In North Carolina there are approximately 34,000 residents in adult care homes (ACHs). Approximately 40% of these residents have urinary incontinence, and others require assistance with toileting. High prevalence of cognitive impairment, few licensed staff, and low staff-to-resident ratios in ACHs make behavioral techniques used in community-dwelling populations and toileting programs used in nursing homes inappropriate for these residents. This program was implemented using a two-level approach (facility and individual resident) and uses an education consultation approach for implementation.

Development of a cervical cancer education program for native American women in North Carolina.

The North Carolina Native American Cervical Cancer Prevention Project is a five-year, NCI-funded public health education program. The project was developed to address the problem of excess mortality from cervical cancer among Native American women by increasing screening and follow-up of abnormal cervical smears. This paper describes the process of developing and implementing the intervention, an individualized health education program. Development of the intervention was guided by the health belief model, social learning theory, self efficacy theory, and PRECEDE, a planning model. Community analysis revealed that the target populations had limited awareness of cervical cancer as a specific type of cancer, and had an experientially-based pessimistic outlook regarding survival with cancer. Steps in developing the cervical-cancer prevention program included 1) development of objectives, 2) selection of strategies and development of cervical cancer education materials, 3) pretesting and revision, and 4) implementation, monitoring, and further revision. Native American lay health educators were recruited and trained to deliver the program. The experience of developing and implementing the individualized health education program suggests that the design of health education programs for Native Americans should begin with examination of basic assumptions regarding the nature of health and illness in the target population. The unique cultures and the diversity of Native American populations are critical factors in the development of health education programs for them.

Detection of acute infections during HIV testing in North Carolina.

BACKGROUND: North Carolina has added nucleic acid amplification testing for the human immunodeficiency virus (HIV) to standard HIV antibody tests to detect persons with acute HIV infection who are viremic but antibody-negative. METHODS: To determine the effect of nucleic acid amplification testing on the yield and accuracy of HIV detection in public health practice, we conducted a 12-month observational study of methods for state-funded HIV testing. We compared the diagnostic performance of standard HIV antibody tests (i.e., enzyme immunoassay and Western blot analysis) with an algorithm whereby serum samples that yielded negative results on standard antibody tests were tested again with the use of nucleic acid amplification. A surveillance algorithm with repeated sensitive-less-sensitive enzyme immunoassay tests was also evaluated. HIV infection was defined as a confirmed positive result on a nucleic acid amplification test or as HIV antibody seroconversion. RESULTS: Between November 1, 2002, and October 31, 2003, 109,250 persons at risk for HIV infection who had consented to HIV testing presented at state-funded sites. There were 606 HIV-positive results. Established infection, as identified by standard enzyme immunoassay or Western blot analysis, appeared in 583 participants; of these, 107 were identified, with the use of sensitive-less-sensitive enzyme immunoassay tests, as recent infections. A total of 23 acutely infected persons were identified only with the use of the nucleic acid amplification algorithm. With all detectable infections taken into account, the sensitivity of standard antibody testing was 0.962 (95 percent confidence interval, 0.944 to 0.976). There were two false positive results on nucleic acid amplification tests. The specificity and positive predictive value of the algorithm that included nucleic acid amplification testing were greater than 0.999 (95 percent confidence interval, 0.999 to >0.999) and 0.997 (95 percent confidence interval, 0.988 to >0.999), respectively. Of the 23 acute HIV infections, 16 were detected at sexually transmitted disease clinics. Emergency measures for HIV prevention protected 48 sex partners and one fetus from high-risk exposure to HIV. CONCLUSIONS: The addition of nucleic acid amplification testing to an HIV testing algorithm significantly increases the identification of cases of infection without impairing the performance of diagnostic testing. The detection of highly contagious, acutely infected persons creates new opportunities for HIV surveillance and prevention.

Risk factors for chronic lung disease in the surfactant era: a North Carolina population-based study of very low birth weight infants. North Carolina Neonatologists Association.

OBJECTIVE: To identify risk factors for chronic lung disease (CLD) in a population-based cohort of very low birth weight infants, born in an era of surfactant usage. We specifically investigated the effects of antenatal steroids, nosocomial infection, patent ductus arteriosus (PDA), fluid management, and ventilator support strategies. METHODS: Data were prospectively collected on 1244 infants born in North Carolina in 1994 with birth weights 500 to 1500 g, and treated at 1 of the 13 intensive care nurseries across the state. The outcome of interest was CLD, defined as dependency on supplemental oxygen at 36 weeks' postmenstrual age. Multivariate odds ratios (OR) and 95% confidence intervals (CI) were estimated with logistic regression models. RESULTS: Among 865 survivors to 36 weeks' postmenstrual age, 224 (26%) had CLD. Nosocomial infection (OR: 2.0; 95% CI: 1.4-3.3), fluid intake on day 2 (OR: 1.06 per 10 mL increase; 95% CI: 1.01-1.11), and the need for ventilation at 48 hours of life (OR: 2.2; 95% CI: 1.3-3.7) were associated with an increased risk of CLD. Among infants ventilated at 48 hours, nosocomial infection (OR: 1.64; 95% CI: 1.02-2.62) and PDA (OR: 1.9; 95% CI: 1.2-3.1) were associated with an increased risk. No association was found with antenatal steroid receipt or increased levels of ventilator support. CONCLUSION: This analysis suggests that with widespread use of surfactant, nosocomial infection, PDA, and water balance persist as risk factors for CLD.

Analysis of climate trends in North Carolina (1949-1998).

North Carolina has one of the most complex climates in the United States (U.S.). Analysis of the climate in this state is critical for agricultural and planning purposes. Climate patterns and trends in North Carolina are analyzed for the period 1949-1998. Precipitation, minimum temperature, and maximum temperature are analyzed on seasonal and annual time scales using data collected from the National Weather Service Cooperative Observer Network. Additionally, changes in patterns of occurrence of the last spring freeze and first fall freeze are investigated. Linear time series slopes are analyzed to investigate the spatial and temporal trends of climate variability in North Carolina. Spatial analysis of climate variability across North Carolina is performed using a geographic information system. While most trends are local in nature, there are general statewide patterns. Precipitation in North Carolina has increased over the past 50 years during the fall and winter seasons, but decreased during the summer. Temperatures during the last 10 years are warmer than average, but are not warmer than those experienced during the 1950s. The warm season has become longer, as measured by the dates of the last spring freeze and first fall freeze. Generally, the last 10 years were the wettest of the study period. These conclusions are consistent with earlier studies that show that the difference between the maximum and minimum temperatures is decreasing, possibly due to increased cloud cover and precipitation. Similarly, these results show that temperature patterns are in phase with the North Atlantic Oscillation and precipitation patterns appear to be correlated with the Pacific Decadal Oscillation.

Tuberculosis knowledge and attitudes among physicians who treat young children in North Carolina, USA.

SETTING: North Carolina, USA. OBJECTIVE: To understand physicians' knowledge and attitudes toward the treatment of young children with latent tuberculosis infection (LTBI) in a low-incidence region. DESIGN: Cross-sectional survey of 525 pediatricians and 525 family practitioners in North Carolina. RESULTS: Of 1050 surveys mailed, 149 (14%) were returned. In the previous year, 96% of responding physicians had treated children who had emigrated from a tuberculosis (TB) endemic country. During the last 2 years, 84% of physicians had not diagnosed any young children with TB disease, and 46% had not treated any young children with LTBI. Most (83%) physicians routinely placed tuberculin skin tests (TSTs), and 26% reported placing > 10 TSTs per month. Experience in treating children with LTBI was the only predictor of TB knowledge. Physicians were particularly confused about two issues: 1) TST among bacille Calmette-Guérin (BCG) vaccinated children and 2) treatment of young children with recent exposure to an adult with infectious TB. CONCLUSIONS: Knowledge of important issues related to management of LTBI in children aged < 5 years was limited among physicians in an area with relatively low TB incidence. Creative methods must be developed to help physicians in low-incidence areas to appropriately diagnose and treat LTBI among young children.
