The association between health care coverage and the use of cancer screening tests. Results from the 1992 National Health Interview Survey.

OBJECTIVES: The authors investigated whether utilization of six different cancer screening tests (mammography, clinical breast exam, Pap smear, Fecal Occult Blood Test, and Digital rectal exam) varied according to type of health care coverage. METHODS: Data on the use of cancer screening tests and coverage in two age groups from a 1992 nationally representative cross-sectional survey of approximately 9,400 adults were analyzed. Multiple logistic regression analysis was used to estimate proportions of persons screened according to type and extent of coverage, adjusted for socioeconomic, demographic, and health status characteristics. RESULTS: Persons aged 40 to 64 years with Medicaid coverage were equally as likely to receive five of six cancer screening tests as those with private fee-for-service coverage, and both groups were much more likely to be screened (70% higher for all six tests) than those who had no coverage. In contrast, persons aged 65 years and older who had supplemental private fee-for-service insurance in addition to Medicare were more likely to receive five of six tests than those with Medicare and Medicaid or those with Medicare only. For all six screening tests, managed care enrollees at all ages were approximately 10% more likely to be screened than persons enrolled in private fee-for-service plans. Fecal Occult Blood Test (25% versus 20%) and digital rectal exams (44% versus 38%) in persons aged 40 to 64 years and mammography (59% versus 48%) and Fecal Occult Blood Test screening (38% versus 30%) in the elderly were significantly more frequent for persons in managed care plans. CONCLUSIONS: The extent of fee-for-service insurance coverage in the traditional indemnity US health care system was positively associated with the use of cancer screening tests. The authors found less difference in use of cancer screening between managed care and fee-for-service care in 1992 than we expected based on earlier research comparing use of preventive services in health maintenance organizations with fee-for-service care.

Effects of transdermal testosterone on cognitive function and health perception in older men with low bioavailable testosterone levels.

BACKGROUND: Many men older than 50 years have bioavailable testosterone levels below the reference range for young adult men. The impact of the decreased androgen levels on cognition and health perception has received little attention. METHODS: Sixty-seven men (mean age 76 +/- 4 years, range 65-87) with bioavailable testosterone levels below 128 ng/dl (lower limit for adult normal range) were randomized to receive transdermal testosterone (2-2.5 mg patches/d) or placebo patches for 1 year. All men received 500 mg supplemental calcium and 400 IU vitamin D. Outcome measures included sex hormones [testosterone, bioavailable testosterone, sex hormone binding globulin (SHBG), estradiol, and estrone], cognitive tests (Digit Symbol, Digit Span, Trailmaking A and B), health perception (Medical Outcome Survey Short-form 36 or SF-36), lower extremity muscle strength and power, and calcium intake. RESULTS: Twenty-three men (34%) withdrew from the study; 44 men completed the trial. Bioavailable testosterone levels increased from 93 +/- 34 (SD) to 162 +/- 100 ng/dl (p <.002) at 12 months in the testosterone group (n = 24) while no change occurred in the control group (n = 20). While there was no change in estradiol levels in either group, estrone levels increased in the testosterone group (28 +/- 7 to 32 +/- 9 pg/dl, p =.017). Scores on the Digit Symbol test improved in both the testosterone and placebo groups. Scores on Trailmaking B improved in men treated with testosterone (p <.005), although the changes were not statistically different from the changes seen in the placebo group. Twelve-month scores on Trailmaking B for the entire group were correlated with 12-month testosterone levels (p =.016). Scores for health perception measured by SF-36 did not change significantly, though scores of mental and general health declined in both groups during the 12-month intervention. Twelve-month bioavailable testosterone scores were directly correlated with scores for physical role (p =.022), vitality (p =.036), and the physical composite score (p =.010). CONCLUSIONS: Transdermal testosterone treatment in men with low bioavailable testosterone levels does not impair and may improve cognitive function. Treatment did not improve health perception but this may have been due to the side effects of skin irritation suggested by similar reactions in both the testosterone and placebo groups.

Ethnicity, traditional health beliefs, and health-seeking behavior: guardians' attitudes regarding their children's medical treatment.

INTRODUCTION: The purpose of this research was to examine ethnic variation in attitudes about traditional health beliefs concerning the use of home remedies and self-medicating behavior among guardians for their children. METHOD: As part of a community health care utilization study of children, questions were included regarding guardians' traditional health beliefs. Survey questions were adapted from the National Health Interview Survey or developed by the researchers. A cross-sectional stratified sample of households with children (n = 1606) were surveyed by random digit dialing. RESULTS: Two of four traditional health belief questions were significantly associated with ethnicity. Differences were observed for (a) guardians' willingness to treat their children with home remedies rather than use a health care provider if the condition was nonemergent and (b) their belief that some home remedies are better than prescribed drugs for curing illness (P <.01). DISCUSSION: Some traditional health beliefs among guardians differed by ethnicity. However, differences between the two minority groups were as pronounced as differences between minority and nonminority guardians. An understanding of the diversity of ethnic attitudes about traditional health beliefs is necessary for those involved in the delivery of health care. A stereotypical view that larger proportions of minorities subscribe to traditional health beliefs than do Whites is not supported in this research.

Health problems encountered by nurse-practitioners and physicians in obstetric-gynecologic ambulatory care clinics.

This study documents the distribution of health problems managed by obstetric-gynecologic nurse-practitioners (OB-GYN NPs) and obstetrician-gynecologists in community-based ambulatory care settings, and examines the effects of provider group on the distribution of health problems. A proportional sampling technique was used in selecting a sample of 3,873 visits for analysis from a total of 5,889 patient visits made to three community-based clinics during an 18-week period from February to June, 1978. A Patient Encounter Form was devised to record basic encounter data and the health problems managed by providers. The International Classification of Diseases, 9th revision (ICD-9-CM) was used as the coding system. Results indicated: (1) in each clinic, the distribution of health problems based on the three-digit headings of ICD-9-CM differed significantly between the OB-GYN NPs and the obstetrician-gynecologists; (2) the distributions of frequently reported health problems were clinically similar for OB-GYN NPs and obstetrician-gynecologists; and (3) the distributions of health problems with V codes were clinically similar for the two provider groups. Data indicate the OB-GYN NP caseloads are similar to those of obstetrician-gynecologists in frequently managed health problems and in wellness emphases. Nurse-practitioners are appropriate collaborators with obstetrician-gynecologists in the provision of primary health care for women.

Digital biology: an emerging and promising discipline.

This article examines the role of computation and quantitative methods in modern biomedical research to identify emerging scientific, technical, policy and organizational trends. It identifies common concerns and practices in the emerging community of computationally-oriented bio-scientists by reviewing a national symposium, Digital Biology: the Emerging Paradigm, held at the National Institutes of Health in Bethesda, Maryland, November 6th and 7th 2003. This meeting showed how biomedical computing promises scientific breakthroughs that will yield significant health benefits. Three key areas that define the emerging discipline of digital biology are: scientific data integration, multi-scale modeling and networked science. Each area faces unique technical challenges and information policy issues that must be addressed as the field matures. Here we summarize the emergent challenges and offer suggestions to academia, industry and government on how best to expand the role of computation in their scientific activities.

Needs analysis for tele-neurophysiology in the Irish North-Western Health Board.

No clinical neurophysiology (CN) service is currently provided by the North-Western Health Board (NWHB) region in Ireland. Digital technology associated with CN is compatible with tele-neurophysiology service development and may increase the efficiency of patient care in remote areas. This study was conducted to assess the need for CN in the NWHB with a view to implementing a tele-neurophysiology service for the region. A retrospective audit of investigations performed at six CN departments in Dublin compared patient groups from regions with (Eastern Regional Health Authority--ERHA) and without (NWHB) local CN departments. 4954 records were audited. CN activity was lower than internationally expected (ERHA group 52% of expected, NWHB group 23% of expected). The 2 groups differ in the specialty of referring clinician (p < 0.0001). NWHB patients are more likely to be referred by clinicians outside their region (p < 0.0001) and wait longer for appointment (p < 0.0001). While there is an unmet demand for CN services in Ireland generally, the population of the NWHB is further disadvantaged. Tele-neurophysiology has the potential to provide fairer access to CN services across the country. The data from this study provide a baseline against which the outcome of investment in CN can be monitored and evaluated.

CARDIOMEDIA: a communicable multimedia medical record on Intranet and digital optical memory card.

As part of French health reform, French physicians were computerised by the end of 1998. A specific Intranet network will be used to communicate medical data between the health professionals. The objectives of the CARDIOMEDIA project were to develop and evaluate the feasibility of a coronary multimedia data record stored on an optical card and communicable on Intranet within the hospital. Patients treated by angioplasty at the University Hospital of Rennes participated in the experiment. In general, patients are treated in the University Hospital and are followed up by another health care provider closer to their home. The patient leaves the University Hospital with his card, which is directly available elsewhere for emergency or for consultation. This approach is assumed to reduce the number of examinations and to offer a better patient follow-up. The CARDIOMEDIA card is a specialised record including various data types: text, images, image sequences of coronarography and ECG signals. For this purpose an optical card with its large memory is very convenient. We used the DICOM format for image exchange and management. It is combined with CARDIOMEDIA specific compressing software. For the multimedia record the HTML format and web Intranet method are chosen. This provides an intuitive interface which can combine various data types and helper applications like a DICOM image viewer.

[Digital fluorographs for early detection and diagnosis of pulmonary tuberculosis].

Under the conditions of out health care system it is best to install first small-dose digital fluorographs at urban polyclinics and use as movable plants. The basis of a diagnostic study of pulmonary tuberculosis is to monitor X-ray changes in the process by a series of X-ray images and tomographic scans. At the same time paper imprints obtained by printers (including laser ones) lose as much as 30% of image details so computer images rather than hard paper copies should be used for comparison in practice of the X-ray units of dispensaries. Computers are required for dispensaries: for each X-ray specialist, the head of a unit, deputy head physician in therapeutics so that the use of a digital fluorographic plant should be as much as effective.

The association between women's health information use and health care visits.

OBJECTIVE: To determine the effect of the type of information sources used on health services use. METHODS: Population-based random-digit dialing survey of 498 women, between December 1999 and January 2000, on use of health information sources and health visits. RESULTS: After adjustment for sociodemographic and medical factors, use of print health media and computer-based resources was associated with 1.9 and 1.6 more visits, respectively compared to non-use (Regression coefficients 1.9; [95% confidence interval {CI} 0.1, 3.7] and 1.6; [95% CI 0.3, 3.0]). CONCLUSIONS: Print health media and computer-based sources are associated with a higher number of health care visits.

A comparison of 2 patient populations using fractal analysis.

This study was undertaken to demonstrate that the fractal dimensions calculated using digitized non-standardized, clinical radiographs of mandibular alveolar bone from a population of patients diagnosed with periodontitis are statistically different from fractal dimensions calculated from another population diagnosed as having gingivitis or healthy gingiva. The fractal dimension was calculated using a public domain fractal analysis program distributed by the National Institutes of Health (NIH). Fractal dimensions were calculated from digitized clinical radiographs for 29 patients diagnosed with healthy gingiva and/or gingivitis and 32 patients diagnosed with periodontitis and compared. To estimate the reproducibility of the technique, we recalculated the fractal dimension from images of the gingivitis patients 3 months after the original calculations and compared them to the originals. A 2 sample, 2-tailed Student t test showed the gingivitis data group to be different from the periodontitis data group (P = 0.0012). The original gingivitis and repeat gingivitis groups fractal dimension calculation were the same and analysis showed the two data sets were not significantly different (P = 0.99). We found that: 1) fractal dimensions could be used to distinguish between gingivitis and periodontitis patient groups; 2) fractal dimensions could be calculated from non-standardized clinical radiographs; and 3) fractal dimensions for gingivitis patients were reproducible over a 3-month period.

Higher prevalence of childhood sexual abuse among Latino men who have sex with men than non-Latino men who have sex with men: data from the Urban Men's Health Study.

OBJECTIVE: The prevalence of childhood sexual abuse among Latino adult men who have sex with men who live in the US was estimated because a history of childhood sexual abuse increases HIV sexual risk behaviors and other negative health outcomes in adulthood. METHOD: The Urban Men's Health Study is a random-digit telephone probability survey of 2881 adult men who have sex with men (MSM) aged 18 years or older residing in San Francisco, New York, Los Angeles, and Chicago. Self-reported history of childhood sexual abuse was the main outcome measure gathered from 2692 MSM. RESULTS: A significantly higher proportion of Latino MSM reported sexual abuse before age 13 (22%) than did non-Latino MSM (11%). CONCLUSIONS: Latino MSM are twice as likely to report a history of childhood sexual abuse than are non-Latino MSM. Given the association between childhood sexual abuse and increased risk for HIV and other negative health outcomes, health providers must remain vigilant to the possibility of childhood sexual abuse histories among their Latino patients.

Assessing health consumerism on the Web: a demographic profile of information-seeking behaviors.

The growing diversity of the online health information community is increasingly cited as a limiting factor related to the potential of the Internet as an effective health communication channel and information resource. Public-access Internet portals and decreasing costs of personal computers have created a consensus that unequal access to information, or a "Digital Divide," presents a like problem specific to health care consumers. Access to information, however, is an essential part of the consumer-centric framework outlined in the recently proposed U.S. National Health Information Infrastructure (NHII) and Health Architecture initiatives. To date little research has been done to differentiate the types of health information sought on the Web by different subgroups, linking user characteristics and health-seeking behaviors. Data from a study of consumer Web search activity in a post-intervention era serves as a natural experiment, and can identify whether a "digitally underserved group" persists in the United States. Such an environment would serve to exclude traditionally underserved groups from the benefits of the planned national heath information infrastructure. This exploratory technology assessment study seeks to differentiate and delineate specific behaviors, or lack of desired behaviors, across targeted health care subgroups. Doing so allows the design of more effective strategies to promote the use of the Web as a health education and health promotion tool, under the envisioned shared decision-making, consumer-centric health information model.

Suspected infant abuse: radiographic skeletal survey practices in pediatric health care facilities.

PURPOSE: To determine current national radiographic skeletal survey imaging practices, including migration to digital technologies, for evaluation of suspected infant abuse. MATERIALS AND METHODS: Of 155 children's health care facilities in the United States in which radiographic skeletal surveys are performed for suspected infant (<1 year old) abuse, 137 (88.4%) agreed to complete a questionnaire. Questions included facility type, imaging department volume, radiographic equipment, and details of skeletal survey imaging practices. Statistical analysis was performed with chi(2), Fisher exact, Pearson correlation, Spearman rank correlation, and Student t tests. RESULTS: One hundred seven completed questionnaires were returned. Forty-seven (43.9%) facilities used screen-film imaging; 60 (56.1%) used digital. Of screen-film users, 25 (53.2%) had already migrated or planned to migrate to digital within 1 year. Of screen-film users, 27 (60.0%) reported use of a high-detail imaging system, while 13 (21.7%) digital users employed a high-resolution technique (P < .001). Eighty-four (78.5%) facilities reported more than 10 images in their protocol, and 45 (42.0%) specified more than 15 images. Only one (0.9%) facility obtained fewer than three images. Upper extremities were imaged separately with at least two exposures in 81 (75.7%) facilities. Lower extremities were imaged separately with at least two exposures in 82 (76.6%) facilities. One hundred five (98.1%) facilities reported acquisition of lateral spinal views. CONCLUSION: Within U.S. pediatric health care facilities, most skeletal surveys in cases of suspected infant abuse include separate frontal views of the appendicular skeleton and frontal and lateral views of the axial skeleton. Imaging protocols and other image quality determinants vary widely, and as U.S. pediatric health care facilities migrate from film-based to digital imaging technology, imaging practices directly applicable to the digital environment are being retained; however, less attention is being paid to technical elements specific to digital imaging that affect high-detail image quality.

Impact of a rural domestic violence prevention campaign.

Domestic violence is a prevalent health problem that in rural areas is further complicated by limited services, social isolation and the lack of privacy. Little is known about the impact of public health education on awareness, attitudes and behavior of the general public regarding domestic violence. This study sought to measure change in societal attitudes and behavioral intention in response to a seven-month public health education campaign targeting domestic violence in a rural county. From October 1998 to April 1999, the campaign used radio advertisements, posters, mailings to libraries and clergy, printed media articles, printed advertisements and health facility modifications. A random-digit-dialing telephone survey was used to evaluate attitudinal and behavioral changes in the intervention and comparison counties before and after the campaign. The response rates for the pre- (n =378) and postcampaign (n=633) surveys were 73 percent and 65 percent, respectively. Statistically significant increases in slogan and advertising recognition occurred in the intervention county (P=0.03), particularly among men recalling the campaign slogan (P=0.006). In a vignette regarding actions to be taken if the neighbor next door was abusing a partner, significant increases occurred in the intervention county in the percentage of respondents who thought that most people would talk to the victim (P=0.04), consult with friends (P=0.002) or talk to a doctor (P=0.004). Domestic violence agency hotline calls in the intervention county doubled following the campaign. Local public health education campaigns in a rural setting may be a valuable adjunct to national efforts, especially in reaching men.

The fusion of gerontology and technology in nursing education: History and demonstration of the Gerontological Informatics Reasoning Project--GRIP.

Phase I of our Gerontological Reasoning Informatics Project (GRIP) began in the summer of 2002 when all 37 senior undergraduate nursing students in our accelerated BSN nursing program were given PDAs. These students were oriented to use a digitalized geriatric nursing assessment tool embedded into their PDA in a variety of geriatric clinical agencies. This informatics project was developed to make geriatric nursing more technology oriented and focused on seven modules of geriatric assessment: intellect (I), nutrition (N), self-concept (S), physical activity (P), interpersonal functioning (I), restful sleep (R), and elimination (E)--INSPIRE. Through phase II and now phase III, the GRIP Project has become a major collaboration between the College of Nursing & Health Professions and College of Information Science and Technology at Drexel University. The digitalized geriatric nursing health assessment tool has undergone a second round of reliability and validity testing and is now used to conduct a 20 minute comprehensive geriatric health assessment on the PDA, making our undergraduate gerontology course the most high tech clinical course in our nursing curriculum.

Psychosocial and medical predictors of colorectal cancer screening among low-income medical outpatients.

BACKGROUND: Identification of factors related to colorectal cancer screening (CRC) and intent to obtain fecal occult blood tests (FOBTs) among low-income persons are important because CRC incidence and mortality are higher among socioeconomically disadvantaged populations. METHOD: Participants were 193 individuals 50 years of age and older. CRC screening and intent to obtain FOBTs were dependent measures. Demographic variables, objective risk factors, and health beliefs were independent measures. RESULTS: Digital rectal examinations and FOBTs were obtained by 41% and 22%, respectively, during the previous year. Flexible sigmoidoscopies were obtained by only 19% of those 55 years of age and older during the previous five years. Multivariate analyses showed that family history of CRC, personal history of polyps, and physician recommendation were the strongest predictors of CRC screening. Family history of CRC and self-efficacy were related to intent to obtain FOBTs. CONCLUSIONS: Results suggest the importance of physician assessment of personal and family CRC risk factors, as well as recommendation of CRC screening, to all patients as part of routine medical care.
