Pathologic findings from the Maryland Women's Health Study: practice patterns in the diagnosis of adenomyosis.

Criteria for the diagnosis of adenomyosis vary widely in practice. The reported frequency of adenomyosis in hysterectomy specimens varies from 5-70% in published series. In this study, 1252 pathology reports on hysterectomy specimens from women enrolled in the Maryland Women's Health Study were reviewed. The frequency of adenomyosis was calculated based on two subgroups: 1114 reports from 15 hospitals, and 705 reports signed by 25 pathologists. The frequency of diagnosis of adenomyosis ranged from 12% to 58% among the 15 hospitals, and 10% to 88% among the 25 pathologists. This wide variation could not be explained by differences in patient age or number of pregnancies, factors known to correlate with the frequency of adenomyosis. These data suggest that adenomyosis may be overdiagnosed. Stringent and widely accepted criteria for the diagnosis of adenomyosis are needed, as epidemiologic studies of this common condition would be facilitated by the use of standard criteria in practice.

Money, mission, and medicine: an innovative managed care partnership between the community health centers of Maryland and Johns Hopkins University.

Across the nation, states are placing their faith in managed care as the solution to the rising health care costs associated with the Medicaid program. Historical providers of care to the vulnerable and uninsured are competing in this new price-sensitive market while struggling to remain faithful to their missions. In Maryland, a unique partnership between an academic health center (Johns Hopkins HealthCare) and a coalition of community health centers has emerged as a model that promises to preserve the financial and philosophical goals of historical providers.

Racial disparity in psychotropic medications prescribed for youths with Medicaid insurance in Maryland.

DESIGN: A retrospective analysis was conducted using state Medicaid prescription drug reimbursement claims for youths aged 5 through 14 years according to the race of the recipients of psychotropic and medical drugs. METHOD: A person-based data set was created from Medicaid administrative data for fiscal year 1991 from the state of Maryland to yield the following: (1) estimates of prevalence of prescription recipients per 100 eligible enrollees; (2) relative prescription use ratios according to race (African-American versus Caucasian); and (3) the interrelation of race and geographic region on prescription prevalence. RESULTS: Five major findings were observed: (1) African-American youths with Medicaid insurance aged 5 through 14 were less than half (39% to 52%) as likely to have been prescribed psychotropic medications as Caucasian youths with Medicaid insurance; (2) the relative difference for nonpsychotropic medication classes was much less pronounced: African-American youths were prescribed nonpsychotropic medications at a rate 60% to 87% of the Caucasian youths' rate; (3) the stimulants (essentially methylphenidate) had the most disparate African-American/Caucasian ratio (1:2.5); (4) the racial disparity for psychotropics was not altered by partial (noncontinuous enrollment) eligibility status; and (5) although geographic variation reduced the racial disparity, the substantial racial difference (1:2.0) remained. CONCLUSION: Compared with Caucasians, African-American youths aged 5 through 14 with Medicaid insurance coverage showed a distinctly lower rate of treatment with psychopharmacological agents.

Practice changes in response to the malpractice litigation climate. Results of a Maryland physician survey.

Data from a 1987 survey of Maryland physicians in three specialties (internal medicine, family or general practice, and obstetrics-gynecology) were used to study the types of changes physicians have made in their practices during the last 2 years as a result of the current malpractice litigation climate. Overall, 51% reported making some type of practice change. The practice changes that physicians reported reflect both risk-reduction (e.g., increased use of tests) and risk-avoidance (e.g., cutting back high-risk patients) strategies, although risk-reduction actions were reported more frequently. Raising patient fees was also reported. Specialty predicts whether or not physicians make each type of change; in particular, obstetrician-gynecologists are more likely to report practice changes of all types. Prior litigation experience does not, in general, predict practice changes. The implications of the types of changes reported for access to care and costs of care were considered.

The relation of parent and provider characteristics to vaccination status of children in private practices and managed care organizations in Maryland.

OBJECTIVES: This study sought to identify provider practices and policies in private pediatric settings that relate to vaccination status, controlling for the characteristics of the children served. METHODS: Vaccination data came from the medical records of 709 randomly selected 2-year-old children at 18 private practices and managed care organizations in Maryland, family data from 466 telephone interviews with the children's parents, and provider characteristics from 18 site questionnaires and 42 individual physician and nurse practitioner questionnaires. Logistic regression and generalized estimating equations were used to estimate the relation of provider characteristics to vaccination status. Three age-appropriate (AA) and two up-to-date (UTD) vaccination status variables characterized successful vaccination. RESULTS: Approximately 70% of the study children were up-to-date by age 2 years for the full vaccination series, excluding hepatitis B vaccine. Family demographic characteristics were the strongest correlates of undervaccination. Neither parents' knowledge and attitudes about immunization nor the children's insurance coverage was statistically related to vaccination status. Site reminder or follow-up systems and provider perceptions about appointment scheduling and receipt of vaccine information from health departments were positively related to vaccination. Concern for liability was associated with a reduced odds of age-appropriate and up-to-date vaccination. CONCLUSIONS: Family demographics strongly correlate with vaccination status; however, they are generally not modifiable. This study's findings encourage providers to operate a tracking system, to remain current on immunization recommendations, to use all clinical encounters to screen and vaccinate children, and to ensure the availability and convenience of vaccination services.

Gonorrhea prevalence in the Maryland state prisons.

During a 6-month period from July 1 through December 31, 1986, 2,598 consecutive men were screened for gonorrhea upon entry into the Maryland Division of Corrections. Twenty-eight men (1.1%) demonstrated positive cultures for gonorrhea with 27 of them (92%) asymptomatic. This prevalence is substantially lower than other rates reported from prisons and detention centers. Although the role of asymptomatic males as a reservoir for gonorrhea has been well delineated, standard recommendations for screening high-risk male populations such as prison inmates have not been established. These data suggest that screening in some correctional facilities may not be cost-effective given the low prevalence observed. In addition, contact tracing may be delayed by long holding periods in local detention facilities prior to transfer to the state prison system. These data underscore the need for additional analysis to determine the most effective program structure for screening in correctional facilities and detention centers.

Extending the REACH of health coverage: a program for the uninsured in Anne Arundel County, Maryland.

The Anne Arundel County Department of Health, in Maryland, is expanding access to care for the uninsured through the development of the Residents Access to a Coalition of Health (REACH) program. The goals of REACH, developed in collaboration with the county medical society, are to improve the quality of health care, decrease unnecessary hospitalizations, and reduce usage of emergency room services among county residents who are ages 19 to 64. This is accomplished through a voluntary network of partners who have formally agreed to accept discounted fees for services. Over 3,200 county residents with a network of 400 providers and three hospitals have received over 4.8 million US dollars of uncompensated care since the program's inception in 1999.

Thoracoscopy/laparoscopy in the staging of esophageal cancer: Maryland experience.

Precise clinical staging of esophageal cancer before treatment is important. Thoracoscopic/laparoscopic (Ts/Ls) staging has been proposed as a promising staging method. This study was conducted to evaluate the potential benefits of Ts/Ls staging over conventional noninvasive clinical staging in patients with esophageal cancer. From 1991 to 1999, 111 patients with esophageal cancer underwent Ts/Ls staging by the University of Maryland Medical System. Pretreatment staging workup included computed tomography, magnetic resonance imaging, and esophageal ultrasonography, followed by Ts/Ls surgical staging. Thoracoscopy was successfully performed in 102 patients and was aborted in 4 patients because of pleural adhesions. Laparoscopy was successfully done in 76 patients and was aborted in 1 patient because of peritoneal adhesion. Sixty-seven patients had both Ts and Ls staging, whereas 35 patients and 9 patients, respectively, had only Ts or Ls staging. Thirteen of 19 patients with clinical T4 disease were downstaged to T3 disease, and 8 patients with clinical T3 disease were upstaged to T4 by Ts/Ls staging. No clinical T1-2 disease was found to be associated with local invasion (T4) by Ts/Ls. Forty-eight and 19 patients had mediastinal and celiac lymph node metastases clinically diagnosed, respectively. Nine (18.8%) and 12 (63.2%) of them were proved by Ts and Ls, respectively. An additional 5 and 16 patients were found to have unexpected mediastinal and celiac lymph node metastases, respectively, by Ts/Ls. Biopsy specimens of pleura, lung, or liver were obtained by Ts/Ls procedures in 17 patients because of suspicious findings of routine imaging studies or unexpected findings during the staging operation. Five patients were found to have distant metastasis, and the presence of metastases in others was excluded. The correlation between Ts/Ls staging and conventional noninvasive clinical staging in the diagnosis of T4 disease, mediastinal lymph node metastasis, celiac lymph node metastasis, and M1 disease was 18.8%, 14.5%, 25.5%, and 20.0%, respectively. Ts/Ls provides more accurate information for evaluating local invasion, lymph node metastasis, and distant metastasis. The poor correlation of staging diagnosis between Ts/Ls and conventional noninvasive clinical examinations suggests that the accuracy of current noninvasive clinical staging is questionable and needs to be improved.

Risk factors for chronic kidney disease: a prospective study of 23,534 men and women in Washington County, Maryland.

Chronic kidney disease (CKD) is an increasing cause of morbidity and mortality in the United States. Prospective data on risk factors for CKD are limited to men, and few studies examine the importance of smoking. The authors performed a community-based, prospective observational study of 20-yr duration to examine the association between hypertension and smoking on the future risk of CKD in 23,534 men and women in Washington County, Maryland. CKD was identified as end-stage renal disease in the Health Care Financing Administration database or kidney disease listed on the death certificate. All cases were confirmed as CKD by medical chart review. Adjusted relative hazards of CKD were modeled using Cox proportional hazards regression including age as the time variable and baseline BP, cigarette smoking, gender, and diabetes status as risk factors. The adjusted hazard ratio (95% confidence interval) of developing CKD among women was 2.5 (0.05 to 12.0) for normal BP, 3.0 (0.6 to 14.4) for high-normal BP, 3.8 (0.8 to 17.2) for stage 1 hypertension, 6.3 (1.3 to 29.0) for stage 2 hypertension, and 8.8 (1.8 to 43.0) for stages 3 or 4 hypertension compared with individuals with optimal BP. In men, the relationship was similar but somewhat weaker than in women, with corresponding hazard ratios of 1.4 (0.2 to 12.1), 3.3 (0.4 to 25.6), 3.0 (0.4 to 22.2), 5.7 (0.8 to 43.0), and 9.7 (1.2 to 75.6), respectively. Current cigarette smoking was also significantly associated with risk of CKD in both men and women (hazard ratio in women 2.9 [1.7 to 5.0] and in men 2.4 [1.5 to 4.0]). A large proportion of the attributable risk of CKD in this population was associated with stage 1 hypertension (23%) and cigarette smoking (31%). In conclusion, CKD risk shows strong graded relationships to the sixth report of the Joint National Committee (JNC-VI) on Prevention, Detection Evaluation and Treatment of High BP criteria for BP, to diabetes, and to current cigarette smoking that are at least as strong in women as in men.

Establishing prevention, education and community awareness through a comprehensive diabetes, hypertension and hypercholesterolaemia screening programme: The Smith Island, Maryland, USA experience.

Glucose screening is essential in providing early detection for diabetes. Screening for hypertension and hypercholesterolaemia in diabetics can help identify clients at an increased risk for morbidity and mortality. Free health screening clinics, which included components based on the ABCs of Diabetes, were set up on Smith Island, Maryland, USA in January 2001. An extensive health history was performed on each clinic attendee and baseline assessment data were collected. To date, 273 residents have been screened at the clinics. Clinic education adopted from the National Diabetes Education Program was provided to all attendees. This programme provided members of the community with a baseline assessment and general information on diabetes prevention, detection and treatment. Positive lifestyle strategies were introduced within the community. Barriers to future disease prevention were identified during the programme.

Epizootic and enzootic aspects of Minchinia nelsoni (Haplosporida) disease in Maryland oysters.

Minichinia nelsoni disease in oysters (Crassostrea virginica) from Marumsco Bar, Pocomoke Sound, Maryland (an estuarine tributary of Chesapeake Bay) was studied for 8 years (1961-68) to determine epizootiologic relationships concerning life cycle of the parasite, pathologic effects on the host, and effects of physical factors on population density and recruitment of the host and parasite. The study period covered pre-epizootic, epizootic, and post-epizootic disease conditions. Data on the native oyster population as well as annual introductions of previously unexposed, susceptible populations of juvenile oysters from 1965-68 were included. Salinity, water temperature, mortality, prevalence, incidence, life cycle stages, gross pathology, and histopathologic relationships were observed. Mortality was high (45-55% per year) during the first 3 years of the study; however, M. nelsoni prevalences were low (less than 25%) and did not clearly imply a cause and effect relationship. Drought conditions that began in the summer of 1963 and continued through 1967 caused higher salinities, and apparently initiated epizootic disease in the native oyster populations. The epizootic peaked in May 1965 with a diagnosed prevalence in native oysters of 70%. Enzootic levels of annual mortality (40% in 1966, 30% in 1967, and 2% in 1968) and fall prevalence (16%, 24%, and 4%) developed after that time. Introduced populations had a typical epizootiologic pattern in 1965 55% annual mortality, 82% incidence) and 1966 (55% annual mortality, 66% incidence) which declined in 1967 (30% annual mortality, 44% incidence) followed by a disappearance of the disease in 1968. Epizootiologic differences noted between native oysters (adult and juvenile) and the introduced juvenile populations were also evident from the stages of the disease. Infections in native animals tended to be less serious, and in many cases were delayed or attentuated, while infections in introduced oysters progressed to advanced or terminal phases. Occult manifestations (mantle recession thought to be due to M. nelsoni in oysters not showing histologic evidence of infection) were absent in introduced populations and common in the native population. These differences are interpreted as evidence of resistance in surviving native oysters and their progency, and may indicate genetic resistance developed by natural selection and manifested by an increased ability to survive and overcome infection.

Maryland veterans' knowledge of risk factors for and signs of oral cancers and their use of dental services.

OBJECTIVES: The purpose of this study was to evaluate outpatient veteran'í knowledge about risk factors for and signs of oral cancers, and their utilization of dental services. DESIGN: Patients receiving primary health care services were surveyed during August 1997. SETTING: Primary health care services at three medical centres within the VA Maryland Health Care System (VAMHCS). SUBJECTS: A total of 135 outpatient veterans were interviewed. INTERVENTION: Questionnaire administered by trained interviewers. MAIN OUTCOME MEASURES: Fifteen percent of the sample were eligible for dental care at the VA, while over 40% of those veterans participating in the study were unaware of their VA eligibility for dental services. Fifty six percent of the total sample received dental services from a private dentist, while 13% reported they had no provider of dental care. Of those not eligible for dental care at the VA (n = 115), the majority (67%) received dental care from a private dentist. Current use of tobacco and alcohol was reported by 27% of the sample. Nonsmokers were more likely to visit the dentist in the previous year than smokers (OR = 2.39, 95% C.I. 1.11,5.12). Although 84% correctly identified tobacco use as a risk factor, only 39% correctly identified regular alcohol use as a risk factor. CONCLUSIONS: Veterans at higher risk for oral cancers were less likely to have visited the dentist in the previous year, and, overall, were ill informed and misinformed about these cancers.

Maryland residents' attitudes toward AIDS and the use of dental services.

This project was conducted to examine the impact of Maryland residents' attitudes about AIDS on dental services utilization. A telephone survey of 1,477 households was conducted (response rate 68.9%). Less than 7 percent of the respondents volunteered a concern about contracting AIDS in the dental office. When asked directly, approximately 35 percent stated they would change dentists if their dentist were treating AIDS patients. Respondents who were most aware of the wide-spread treatment of AIDS patients by dentists were more likely to believe their dentist was treating AIDS patients. Also, they were less likely to report that they would leave the practice of dentists with AIDS or those who treated AIDS patients. It is critical for the public to be educated properly about the continued safety of the dental office and to receive accurate information about AIDS.

Maryland adults' knowledge of oral cancer and having oral cancer examinations.

OBJECTIVES: This study sought to determine (1) knowledge of risk factors for oral cancer, (2) knowledge of signs and symptoms of oral cancers, and (3) factors associated with having had an oral cancer examination among 916 Maryland adults 18 years of age and older. METHODS: A statewide, random-digit dial, computer-assisted telephone survey was conducted. The pretested instrument consisted of 32 questions that required 12 minutes to complete. RESULTS: Overall, level of knowledge about risk factors for and signs and symptoms of oral cancers was low; misinformation was high. Although 85 percent reported hearing about oral or mouth cancer, only 28 percent of the respondents reported having had an oral cancer examination. Of these, 20 percent had the exam during the past year--the recommended frequency for persons 40 years of age or older. In logistic regression analysis, adults more likely to have had an oral cancer examination included those who thought personal behavior causes more cancer than environmental factors; had more knowledge about risk factors for oral cancer; and were 40-64 years of age, white, and better educated than their counterparts (P < .05). The primary reasons for not having an exam were "no reason/didn't know I should" and "doctor/dentist didn't recommend." CONCLUSIONS: These results demonstrate a need for interventions designed to increase knowledge levels of risk factors for, signs, and symptoms of oral cancers and the need for oral cancer examinations; and to increase oral cancer examinations.

Oral cancer knowledge and opinions among Maryland nurse practitioners.

OBJECTIVES: As part of a Maryland statewide oral cancer needs assessment, a census of adult and family practice nurse practitioners was conducted to determine their knowledge of oral cancer risk factors, diagnostic procedures and related opinions. METHODS: Information was obtained through a pretested, 40-item, self-administered mail questionnaire of 389 nurse practitioners. A second complete mailing was sent three weeks after the initial mailing; two postal card reminders were mailed at 10 and 17 days after the second mailing, which yielded a response rate of 56 percent. RESULTS: Most nurse practitioners identified the use of tobacco, alcohol, and prior oral cancer lesions as real risk factors. But only 35 percent identified exposure to the sun as a risk for lip cancer. Respondents were not overly knowledgeable about the early signs of oral cancer, most common forms, or sites for oral cancer. Only 19 percent believed their knowledge of oral cancer was current. Nurse practitioners who reported having a continuing education course on oral cancer within the past two to five years were 3.1 times more likely to have a high score on knowledge of risk factors and 2.9 times more likely to have a high score on knowledge of both risk factors and of diagnostic procedures than were those who had never had a continuing education course. CONCLUSIONS: The reported knowledge of oral cancer, in conjunction with opinions about level of knowledge and training, point to a need for systematic educational updates in oral cancer prevention and early detection.

Predictors of falling in older Maryland drivers: a structural-equation model.

Falls can impair health and reduce quality of life among older adults. Although many factors are related to falling, few analyses examine causal models of this behavior. In this study, factors associated with falling were explored simultaneously using structural-equation modeling. A variety of cognitive, physical-performance, and health measures were administered to 694 older adult drivers from the state of Maryland. The observed and latent variables of age, cognitive ability, physical functioning, health, and falling behavior were used to create a causal model. The model revealed that being older was associated with declines in cognition, and such cognitive declines predicted increased falling. Similarly, poorer health was related to poorer physical functioning, which, in turn, also predicted increased falling. This model indicates that in addition to existing fall-prevention interventions aimed at improving physical functioning, interventions to improve cognition and health might also be effective. It is speculated that fear of falling, which often results in reduced mobility among older adults, might account for the lack of a direct relationship between age and falling. This hypothesis should be examined in further research.

Free-living pathogenic and nonpathogenic amoebae in Maryland soils.

Tests for potentially pathogenic amoebae were carried out on soil samples from the following sites: (i) farmlands fertilized with municipal sewage wastes, (ii) a stream receiving sewage effluent from a sludge lagoon, (iii) a ravine receiving storm runoff from a cattle farm, (iv) farmlands not fertilized with sewage wastes, and (v) a vegetated shoreline of a waterfront estate not used for farming or livestock production. Study sites were located on the eastern shore of Maryland, bordered to the north by Delaware and to the south by Virginia. Twenty-four species of soil amoebae, including five potentially pathogenic Acanthamoeba species (members of the family Acanthamoebidae), were identified. All of the sites yielded two or more of the potential pathogens.
