Development of a provisional physical habitat index for Maryland freshwater streams.

Provisional physical habitat indices were developed and validated for Maryland Coastal and Non-Coastal Plain streams using variables (commonly called metrics) that best discriminated reference and degraded conditions based on biological, chemical and land use data from the 1994-97 Maryland Biological Stream Survey (MBSS). These habitat indices contained variables that described structural, hydrological, vegetative and aesthetic components of stream habitat. Variables with the best discriminatory power for Coastal Plain streams were: instream habitat, velocity/depth diversity, pool/glide/eddy quality, embeddedness, maximum depth and aesthetic rating. Physical habitat variables with the best discriminatory power for Non-Coastal Plain sites were: instream habitat, velocity/depth diversity, riffle/run quality, embeddedness, number of rootwads and aesthetic rating. The overall classification efficiency for index validation was 76% for both indices pooled over both strata. Scaled physical habitat index values (0-100) for both strata identified nearly twice as many good sites (31%) as very poor sites (16%). More than half the Maryland sites were in the poor to fair range (53%).

Foreign medical graduates and Maryland Medicaid.

To determine whether foreign medical graduates provide a disproportionate share of medical care to the poor, Medicaid vendors in Maryland were compared with all licensed physicians in the State. Foreign medical graduates constitute 22 per cent of all physicians in Maryland but 36 per cent of the Medicaid vendors. In addition, of all the vendors for fiscal 1974, 94 per cent who were licensed in 1972 or 1973 were foreign medical graduates. This disproportional representation in the Medicaid program is concentrated in the specialties of general surgery, internal medicine and general practice. Thirty-two per cent of all foreign medical graduates in Maryland are board-certified physicians, but only 22 per cent of those who are Medicaid vendors are board certified. For United States medical graduates, 48 per cent of all physicians are board certified, but this figure increases to 52 per cent for the Medicaid vendors. Finally, representation of foreign medical graduates among Medicaid vendors tends to be highest in areas with the highest physician-to-population ratios and with the highest percentages of total Medicaid payments.

Surgical rates and operative mortality for open and laparoscopic cholecystectomy in Maryland.

BACKGROUND: Since 1989, laparoscopic cholecystectomy has been widely adopted as a treatment for gallstone disease. We analyzed the association between the introduction of this procedure and three variables: the rate at which cholecystectomy was performed in Maryland, the characteristics of patients undergoing cholecystectomy in routine clinical practice, and operative mortality. METHODS AND RESULTS: We used 1985-1992 hospital-discharge data from all 54 acute care hospitals in Maryland, to identify open and laparoscopic cholecystectomies, characteristics of patients undergoing these procedures, and deaths occurring during hospitalizations in which these procedures were performed. The annual rate of cholecystectomy, adjusted for age, rose from 1.69 per 1000 state residents in 1987-1989 to 2.17 per 1000 residents in 1992, an increase of 28 percent (P < 0.001). As compared with patients undergoing open cholecystectomy, patients undergoing laparoscopic cholecystectomy tended to be younger, less likely to have acute cholecystitis or a common-duct stone, and more likely to be white and have private health insurance or belong to a health maintenance organization (P < 0.001). Although the operative mortality associated with laparoscopic cholecystectomy was less than that with open cholecystectomy (adjusted odds ratio, 0.22; 95 percent confidence interval, 0.13 to 0.37) and the overall mortality rate for all cholecystectomies declined from 0.84 percent in 1989 to 0.56 percent in 1992, there was no significant change in the total number of cholecystectomy-related operative deaths because of the increase in the cholecystectomy rate. CONCLUSIONS: In Maryland, although the adoption of laparoscopic cholecystectomy has been accompanied by a 33 percent decrease in overall operative mortality per procedure, the total number of cholecystectomy-related deaths has not fallen because of a 28 percent increase in the total rate of cholecystectomy.

Utilization and cost of serologic tests for Lyme disease in Maryland.

To ascertain use of serologic tests for Lyme disease (LD) in Maryland, all laboratories registered with the State Health Department were surveyed. Results show that from 1992 to 1995, 17 laboratories performed 100,000 serologic tests costing $7.1 million on Maryland residents; 90% of these tests were EIAs. The proportion of positive EIAs increased from 3.4% in 1992 to approximately 7.0% in 1994 and 1995, and the percentage of positive second tests (Western blot, WB) fell from 7.9% to 5.0%-5.5%. The large number of EIAs performed in comparison with the low incidence of LD in the state results in a low predictive value of a positive EIA test. Therefore, the WB is indicated to confirm equivocal and positive EIA tests when characteristic clinical findings of LD are not present. The 30,000 tests for LD performed annually on Maryland residents at a cost of over $2 million in direct medical costs must be added to the public health burden of LD in this state.

Effects of Maryland's law banning "Saturday night special" handguns on homicides.

Small, inexpensive, often poorly made handguns known as "Saturday night specials" are disproportionately involved in crime. Maryland banned the sale of Saturday night specials effective January 1, 1990. During the 2 years between the law's passage in 1988 and its effective date, legal handgun sales in Maryland were 34% higher than expected (p = 0.09). Interrupted time-series analysis of age-adjusted homicide rates for 1975-1998 with statistical controls for trends in two neighboring states, social and economic variables, and temporal patterns in Maryland's homicide rates was used to assess the effect of the law. Estimates of the Saturday night special ban effects depended on the assumption made about the timing of the law's effects. Models that assumed a delayed or gradual effect of the Saturday night special ban produced estimates indicating that firearm homicide rates were 6.8-11.5% lower than would have been expected without the Saturday night special ban (p < or =0.05). The model that assumed an immediate, constant change in response to the law showed no law effect, unless an outlier was excluded from the analysis. Excluding this outlier, the model estimated a 15% increase in firearm homicides associated with the Saturday night special ban. None of the models revealed significant law effects on nonfirearm homicides.

Survival differences associated with treatment of cytomegalovirus retinitis in Maryland patients with AIDS, 1987-1994.

Differences in survival related to treatment of cytomegalovirus (CMV) retinitis in AIDS patients were studied. The medical records of adult AIDS patients who had been diagnosed with CMV retinitis in a Maryland inpatient facility between September 1987 and September 1994 were reviewed to assess determinants of survival, including treatment with ganciclovir and foscarnet, use of zidovudine, and demographic characteristics. The review was based on inpatient and outpatient medical records and computerized data from the Maryland HIV Information System. Of 212 AIDS patients with CMV retinitis, 123 (58.0%) were treated exclusively with ganciclovir, 55 (25.9%) received foscarnet only, and the remaining 34 (16.1%) received both ganciclovir and foscarnet at some point after their diagnosis for CMV retinitis. Patients who received both drugs survived significantly longer after the diagnosis than patients who received either drug by itself. The median time from diagnosis of CMV retinitis to death was 464 days for patients receiving both drugs, 225 days for ganciclovir recipients, and 202 days for foscarnet recipients. Other positive predictors of survival were male sex and use of zidovudine. Among Maryland adults with AIDS who were treated for CMV retinitis between September 1987 and September 1994, the most common treatment for the eye infection was ganciclovir. Patients receiving both ganciclovir and foscarnet survived longer than those treated with either drug alone.

The public health impact of Lyme disease in Maryland.

The purpose of this study was to estimate the health burden imposed by Lyme disease (LD) in Maryland during 1992 and 1993. A cross-sectional 1-in-15 survey of physicians (total, 1200) in Maryland was conducted to estimate the incidence of diagnosed LD, presumptive cases of LD, patients with tick bites, and diagnostic tests ordered for LD. Results show that LD is underreported by 10- to 12-fold in Maryland, that 80% of cases are managed by primary care physicians, and that there is discordance between the actual clinical treatment of patients and the recommended approach. In addition, the much greater numbers of patients treated for presumptive LD, seen and given prophylaxis for tick bites, and having diagnostic tests indicate that real and perceived LD is a far greater public health problem and uses more medical resources than official surveillance data suggest.

Heart disease, cancer, and stroke in Maryland.

Maryland has higher mortality rates from heart disease, cancer, and stroke (HCS) than the United States as a whole. More than 50% of deaths from HCS are premature, occurring before age 75. The health care and indirect costs from these three diseases total approximately $4.4 billion annually, placing a major economic burden on the state. A large body of scientific literature has shown the potential for the prevention of HCS. Currently, Maryland, like virtually all states, lacks the type of systematic, well-coordinated, comprehensive intervention campaign needed to lower morbidity, mortality, and health care costs from these three diseases. Such a campaign has now been planned by the University of Maryland at Baltimore. Similar campaigns are needed throughout much of the United States.

Do racial disparities exist in access to inpatient stroke rehabilitation in the state of Maryland?

OBJECTIVE: Black patients tend to have a greater number and severity of stroke cases. The literature on access to rehabilitative services shows mixed results ranging from no disparities to limited access among minority populations. This study evaluated the association of race and acute discharge to inpatient stroke rehabilitation in Maryland, a diagnostic related group-and postacute care prospective payment system-exempt state. DESIGN: Data from the Maryland Health Services and Cost Review Commission database for 2000 was used to conduct a cross sectional retrospective review to determine the rate of disposition to inpatient rehabilitation facilities (IRF). Multiple logistic regression analyses evaluated factors associated with discharge to IRF in this population. RESULTS: There were a total of 12,208 patients hospitalized with stroke in the year 2000. Compared with urban-dwelling white patients, black patients who lived in urban dwellings were more likely to be discharged to IRF, OR 1.42, 95% CI (1.06, 1.91). CONCLUSION: In the state of Maryland, urban-dwelling black stroke patients were more likely to be discharged to IRF acutely after stroke. Future studies should assess whether this trend persists in states that have larger rural populations.

The collision of economics and politics in Medicaid managed care: reflections on the course of reform in Maryland.

One of the most dynamic areas of health policy is the transition of Medicaid programs to managed care and market competition. Maryland has been a leader in this trend, initiating three different systems of managed care for the Medicaid population during the 1990s as it searched for an ideal plan. The Maryland experience illustrates the complex new demands that policy makers are facing. Health plans are expected not only to deliver budgetary savings, but also to improve the quality of their services and guarantee a place for safety-net providers in their delivery systems. As a result, there is a sizable gap between the original savings projected for the new Maryland system and its actual capacity for cost containment. The apparent collision between economic assumptions and political realities, however, may point the way to a constructive synthesis--a form of managed care that balances economy with important community, professional, and personal values.

Perspectives of Maryland adult and family practice nurse practitioners on oral cancer.

OBJECTIVES: Because oral and pharyngeal cancer mortality in Maryland ranks seventh among states and sixth for black males, a statewide oral cancer needs assessment was conducted. The purposes of this qualitative descriptive study were to obtain indepth information on nurse practitioners' awareness and opinions of oral cancer, oral cancer examinations, and related factors. These findings were intended to supplement a previous survey conducted among Maryland nurse practitioners. METHODS: A professional focus group moderator conducted one face-to-face focus group with 11 nurse practitioners and one telephone focus group with eight nurse practitioners. Criterion-purposeful sampling and qualitative content analysis were employed. RESULTS: Findings showed that oral cancer is a neglected public health problem and, based on their formal training, not one considered by nurse practitioners to be their responsibility. Although aware of other cancers, none of the nurse practitioners recognized that oral cancer was a public health problem in the state. Numerous barriers were cited for this neglect, including their lack of training and, in one case, unpleasant feelings about examining the mouth. Participants concluded that oral cancer is part of their responsibilities and that they are interested in related continuing education courses. CONCLUSIONS: The focus groups of nurse practitioners provided rich and insightful suggestions for future strategies to help solve the oral cancer problem in Maryland, which supplemented the quantitative mail survey conducted earlier.

Effect of a legislative mandate on mammography use and coding practices in Maryland.

PURPOSE: To analyze the effect of the 1991 Maryland legislative mandate of screening mammography benefits. MATERIALS AND METHODS: Claims submitted between January 1991 and December 1993 for outpatient mammograms obtained in women covered under Blue Cross Blue Shield of Maryland insurance indemnity contracts were analyzed for the distribution of services and charges. RESULTS: For 184,723 women, 285,241 claims were submitted by 851 Maryland providers. Claims for "mammography bilateral," which were considered "diagnostic," represented 67%; 24% were submitted for "screening mammography bilateral," and 9% were submitted for "mammography unilateral." Mammography claims increased only 25% during the 3 years, despite an estimated fivefold increase in the number of women with the screening mammography benefit. Mammography coding shifted from bilateral to screening. CONCLUSION: The number of mammograms obtained increased only modestly after the mandate, but claims coded for mammography bilateral declined dramatically. Removal of financial barriers appears to be insufficient to increase appropriate use of screening mammography.

Diabetes education infrastructure and capacity in hospitals and home health agencies in Maryland and Pennsylvania.

In this study, questionnaire data were described regarding diabetes education program capacity in Maryland and Pennsylvania hospitals, health maintenance organizations (HMOs), and home health agencies (HHAs). Hospitals, HMOs, and HHAs in each state were asked to indicate whether they currently have a diabetes education program and, if not, whether they had such a program anytime within the past 10 years. Home health agencies were less likely to have had programs in the past and more likely to have recently established diabetes education programs. About half of hospitals currently without programs had a program sometime within the past 10 years. Hospitals in Maryland and Pennsylvania responded similarly; Pennsylvania HHAs were more likely to report having diabetes education programs than HHAs in Maryland. On the average, programs showed moderate levels of institutionalization. Respondents to the questionnaire believed that their programs would be sustained; these projections appeared to not be sensitive to availability of reimbursement.

Socioeconomic and racial disparities in cancer risk from air toxics in Maryland.

We linked risk estimates from the U.S. Environmental Protection Agency's National Air Toxics Assessment (NATA) to racial and socioeconomic characteristics of census tracts in Maryland (2000 Census) to evaluate disparities in estimated cancer risk from exposure to air toxics by emission source category. In Maryland, the average estimated cancer risk across census tracts was highest from on-road sources (50% of total risk from nonbackground sources), followed by nonroad (25%), area (23%), and major sources (< 1%). Census tracts in the highest quartile defined by the fraction of African-American residents were three times more likely to be high risk (> 90th percentile of risk) than those in the lowest quartile (95% confidence interval, 2.0-5.0). Conversely, risk decreased as the proportion of whites increased (p < 0.001). Census tracts in the lowest quartile of socioeconomic position, as measured by various indicators, were 10-100 times more likely to be high risk than those in the highest quartile. We observed substantial risk disparities for on-road, area, and nonroad sources by socioeconomic measure and on-road and area sources by race. There was considerably less evidence of risk disparities from major source emissions. We found a statistically significant interaction between race and income, suggesting a stronger relationship between race and risk at lower incomes. This research demonstrates the utility of NATA for assessing regional environmental justice, identifies an environmental justice concern in Maryland, and suggests that on-road sources may be appropriate targets for policies intended to reduce the disproportionate environmental health burden among economically disadvantaged and minority populations.

An analysis of market shares of Maryland hospitals in their service areas.

The study analyzes market shares (or competitiveness) of Maryland hospitals based on a service area definition of hospitals used for acute care planning in Maryland. The study uses this service area definition to analyze market shares of Maryland hospitals, to test them under alternative hypotheses and, finally, to examine the impact of several key variables. The study finds that proximity of other hospitals, and hospital's occupied bed size, have statistically significant impacts on market shares of hospitals irrespective of hospital location in a metropolitan or rural area.

Race and sex differences in the use of cardiac procedures for patients with ischemic heart disease in Maryland.

This study analyzes administrative data from the Maryland Health Services Cost Review Commission to compare differences by race and sex in the use of cardiac procedures performed in hospitals in Maryland. African Americans discharged from Maryland hospitals were less likely than whites to have received cardiac procedures after controlling for age, insurance status, and the number of comorbidities (e.g., hypertension and diabetes). Overall, the general pattern of care suggests that African American women may receive high-technology cardiac treatment significantly less often than all other race and sex categories.

Perspectives of Maryland dentists on oral cancer.

BACKGROUND: Maryland's mortality rate for oral and pharyngeal cancer is seventh highest overall in the United States, sixth highest for men and third highest for African-American men. As part of a statewide needs assessment and in follow-up to a mail survey of Maryland general dentists, focus groups were conducted to obtain more in-depth information about why dentists do not provide a comprehensive oral cancer examination for most of their patients and how to solve this problem from a dentist's perspective. METHODS: A trained focus group moderator conducted two focus groups of general practice dentists in two locations in Maryland. Five major themes emerged from the two focus groups: inaccurate knowledge about oral cancer; inconsistency in oral cancer examinations; lack of confidence in when and how to palpate for abnormalities; lack of time to routinely provide oral cancer examinations; and recommendations to help resolve these issues. CONCLUSIONS: The focus groups provided a rich source of ideas on how to best provide dentists with continuing education about oral cancer prevention and early detection. Participants also provided opinions about the need to improve the public's awareness of oral cancer and its prevention. CLINICAL IMPLICATIONS: Dentists need to include comprehensive oral cancer examinations as part of their routine oral examinations for all appropriate patients.

Diffusion of effective HIV prevention interventions--lessons from Maryland and Massachusetts.

This article describes, compares, and contrasts the contexts, processes, and results of the experiences of Maryland and Massachusetts in diffusing evidence-based interventions. The evolution of first Maryland's, then Massachusetts's, diffusion of effective interventions is described. Both states have extensive experience planning, developing and evaluating individual-, group-, and community-level interventions promoted in the Centers for Disease Control and Prevention's Diffusion of Effective Behavioral Interventions (DEBI) initiative, as well as overcoming many barriers to translate research to practice. This article describes the processes whereby effective interventions were diffused from the planning to evaluation stages. This includes the role of community-planning groups and other local stakeholders in planning, procurement methods, and capacity building approaches. Specific milestones in increasing the evidence basis of program implementation, management, and evaluation are presented. For jurisdictions considering implementing DEBI, the article illustrates core programmatic and infrastructure capacities at the state and vendor level important to success in Maryland and Massachusetts. It also describes how each state's approach to the management and evaluation of prevention programs contributed to the effective diffusion of the behavioral interventions. Finally, this article provides recommendations about remaining gaps in evidence-based interventions to meet "real-world prevention needs" and ways to improve prevention targeting and effectiveness. This article recommends strategies to improve the dissemination of DEBI and other evidence-based interventions nationally.
