Clinical community health: revisiting "the community as patient".

INTRODUCTION: A little over fifty years ago, Edward McGavran, Dean of the University of North Carolina School of Public Health, articulated the concept of treating the community as if it were a patient. Although McGavran was addressing public health practitioners, the concept has applicability in academic medicine and reflects contemporary thought in patient care, research, and education. The goals of this paper are (1) to present a framework through which clinicians can conceptualize the community as an appropriate level of intervention to improve health, to conduct research and to educate students, and (2) to illustrate the framework by presenting information on how programs at Morehouse School of Medicine have used it to organize community-focused initiatives. The concept may be called Clinical Community Health. CLINICAL COMMUNITY HEALTH AND ITS APPLICATIONS AT MOREHOUSE SCHOOL OF MEDICINE: Health problems of communities are more readily understood by clinicians when analyzed in the same way that clinicians analyze the health problems of individual patients: by gathering subjective and objective data, formulating an assessment that is expressed as a problem list, and developing a plan ("SOAP"). The plan is created in consultation with the community, much as a modern physician engages in shared decision-making with a patient rather than issuing "doctor's orders." Similarly, community-based participatory research creates a relationship between the researcher and the community that parallels the relationship between the researcher and the individual research participant in traditional clinical research. When viewed through this lens, the education of students in the community resembles the education of students in the hospital or clinic--both are a type of service-learning. Hence, the community work of faculty is best evaluated and rewarded in a fashion that parallels evaluation of faculty work in the clinic or hospital. This paper reports on our experiences at Morehouse School of Medicine (MSM), a historically black institution in the United States whose mission focuses on primary care and the health of the underserved. We report on our efforts to apply the model in service, research, and education. CONCLUSION: Viewing the community as a patient provides a useful conceptual framework for primary care physicians and other clinicians, since it allows them to recognize that it is not necessary to learn a different conceptual framework to diagnose and treat the community; rather, one can think of the community as a patient and apply a similar approach to that used in the care of individuals.

Evaluating a community-based multiprofessional course in community health.

PURPOSE: To evaluate student response to a community health course taught using a small-group, interdisciplinary, service-learning approach. METHOD: Student evaluations for the course were reviewed for a 3-year period (1994 1997). RESULTS: Student evaluations of the course improved over the 3-year period. A total of 60-76% of the students indicated that they preferred the small-group experiential approach to lectures. Examination of evaluation scores for individual small groups showed that some small groups gave the course very high ratings, while others found the experience inadequate. CONCLUSION: A course in community health is best taught in the community rather than the classroom. A small-group approach may result in a course with considerable variation among groups as a result of variations in community receptivity, faculty skills, and perhaps other factors.

Influence of a rural primary care clerkship on medical students' intentions to practice in a rural community.

The purpose of this study is to examine the relationship of a rural clerkship to medical students' interest in establishing careers in rural communities. The Association of American Medical Colleges Medical School Graduation Questionnaire (GQ) for years 1988 through 1997 was examined to compare the career plans of students graduating from Morehouse School of Medicine (MSM) with those of all students graduating from United States medical schools before the period 1988 through 1992 and after the period 1993 through 1997, after the inception of the rural clerkship at MSM. Select GQ data items examined include student demographics, medical school experiences, and career plans. Statistical analyses were used to compare pre- and post-clerkship responses for MSM students and to compare their responses with the national trends. Results indicate that, following a transition period, MSM students showed an increased preference for a future career in a rural community. A smaller upward trend in the national data was observed. There appears to be an association between the rural clerkship experience at MSM and the stated preferred career choices of the students.

Racial and urban/rural differences in cervical carcinoma in Georgia Medicaid recipients.

BACKGROUND: The authors conducted a study of racial and geographic differences in the occurrence of cervical carcinoma in a population of uniformly low economic status: Georgia Medicaid recipients. METHODS: Medicaid reimbursement claims data for 1992 were used to calculate counts, rates, and black-to-white risk ratios for newly and previously diagnosed cases of cervical carcinoma in metropolitan Atlanta and in the remainder of the state. RESULTS: Among 615,787 female Georgia Medicaid recipients in 1992, 2050 women (333 per 100,000) had a diagnosis of carcinoma of the cervix. Of 111,208 women who had received Medicaid assistance continuously from 1988 to 1992 (5-year eligibles), a new claim for cervical carcinoma was submitted for 110 (99 per 100,000). In both analyses, rates were higher in metropolitan Atlanta than in the remainder of the state. Black women had significantly higher claims rates than white women only in metropolitan Atlanta; risk ratios were 3.7 (95% confidence interval [CI], 1.3-10.8) for new claims among 5-year eligibles, and 3.5 (95% CI, 3.0-4.1) for prevalence. There was no racial disparity in cervical carcinoma rates in rural areas. CONCLUSIONS: The current study data suggest a high risk of cervical carcinoma among metropolitan Atlanta Medicaid recipients, particularly blacks. Data from rural Georgia (but not Atlanta) support the hypothesis that racial differences in cervical carcinoma rates would largely disappear in a population of uniform economic status.

Knowledge, beliefs, attitudes, and cancer screening among inner-city African-American women.

Three hundred twenty-one inner-city African-American women were interviewed to determine their knowledge, attitudes, and beliefs regarding cancer and cancer screening, and their cancer screening histories. The women were recruited from a variety of sources in Atlanta and were interviewed in their homes by trained lay health workers. Half of the subjects had an annual household income of < $15,000. About half had received a Pap smear and clinical breast examination within the year preceding the interviews. For women > 35 years old, 35% had received a mammogram within the recommended interval. Younger women and women with higher incomes were more likely than older women and those with lower incomes to have received a Pap test and clinical breast examination within the preceding year, but income was not significantly associated with mammography histories. In general, women who were more knowledgeable about cancer and its prevention were more likely to have been appropriately screened. However, various attitudes and beliefs regarding cancer generally were not associated with screening histories. We conclude that cancer screening programs for inner-city minority women should focus on improving knowledge levels among older women rather than attempting to alter attitudes and beliefs.

Effect of a cancer screening intervention conducted by lay health workers among inner-city women.

INTRODUCTION: We conducted a randomized controlled trial to determine if an in-home educational intervention conducted by lay health workers (LHWs) could increase adherence among low-income, inner-city, African-American women to breast and cervical cancer screening schedules. METHODS: We recruited 321 African-American women from diverse inner-city sources. After baseline interviews, they were randomly assigned to either the intervention (n = 163) or the control (n = 158) group. Those in the intervention group were visited in their homes up to three times by LHWs who provided a culturally sensitive educational program that emphasized the need for screening. RESULTS: Ninety-three (93) women in the intervention group and 102 in the control group completed the postintervention interview. For Pap smears, the increase in screening was similar in both groups. For clinical breast exams (CBEs), however, there was a modest increase in the intervention group. The improvement was greatest for mammography, for which there was a 10% to 12% increase. Among women who were not on recommended schedules at baseline, the improvement was substantial and greater in the intervention group. CONCLUSIONS: LHWs' intervention appeared to improve the rate at which inner-city women obtained CBEs and mammograms, but had no effect on Pap smears. A high attrition rate weakened our ability to make conclusive statements about the exact impact of the intervention.

Monte Carlo estimation of errors in 13C-NMR relaxation studies of a DNA oligomer duplex.

An analysis of errors has been done with the Monte Carlo method for natural abundance 13C-NMR relaxation studies of a DNA duplex. Repeated measurements of the longitudinal relaxation time, T1, and the heteronuclear NOE were made at 90.6 MHz on the duplexed DNA pentanucleotide, [d(TCGCG)]2. The deviations averaged over all carbons were 13% for T1 and 9% for NOE. These relative deviations were applied to generate 100 values of T1 and NOE with normal distributions about the measured mean values for each carbon. A new version of MOLDYN, called McMOLDYN, has been written, which was used to generate 100 values of T1 and NOE with normal distributions corresponding to the measured errors; the same error distributions were also applied to measurements at 125.8 MHz. The order parameter, S2, and the effective internal correlation time, tau e, in the Model-Free Approach have been optimized from the distributions simulated by McMOLDYN. McMOLDYN also permits the automated entry of multiple sets of initial guesses for the output parameters S2, tau e, and tau m. In addition, McMOLDYN adds cross-relaxation terms from chemical shift anisotropy, increasingly important as spectrometer magnetic fields get higher. Between the two parameters optimized, S2 has the smallest relative error, estimated at 15% on average, which means that S2 is a well-defined parameter. However, tau e is very poorly defined with the average relative error estimated 85%; it is typically found in the range of 30-300 ps.

Recruitment and retention of subjects for a longitudinal cancer prevention study in an inner-city black community.

Recruiting and retaining subjects for longitudinal prevention trials is challenging. The inherent difficulties are compounded when the trial is to take place in a low-income minority community, since prevention is a low priority among residents of such communities, and research is viewed with suspicion. We present our experiences in attempting to recruit and retain low-income black women living in inner-city Atlanta for a trial of an educational intervention to promote screening for cancer. The intervention was conducted in the home by trained lay health workers. We found that recruitment was more successful when we recruited directly from the community than when we recruited from the patient registry of a primary health care center. The attrition rate over an 18-month period was high. Among members of the intervention group, those retained in the study tended to be wealthier and better educated and were more likely to be married and employed than those who dropped out. It seems probable that women of lower socioeconomic status found our intervention to be intrusive or burdensome. Among the controls, socioeconomic factors did not discriminate between those who completed the study and those who did not; loss to follow-up in this group was associated only with younger age. In conducting research of this type in low-income minority communities, special attention must be given to issues of recruitment and retention if the validity of the study is to be preserved.

Maternal factors, birthweight, and racial differences in infant mortality: a Georgia population-based study.

Black infant mortality rates (IMRs) are approximately twice those of whites in Georgia and nationwide. This study evaluates maternal factors, particularly marital status, that influence racial differences in infant mortality. Population-based data on 565,730 live births and 7269 infant deaths in Georgia from 1980 to 1985 were examined. The IMR ratio for unmarried compared to married mothers was calculated and adjusted singly for maternal education, age and race, and infant birthweight. In addition, racial differences in IMR were estimated using stratified analysis on the basis of four factors: infant birthweight, maternal age, marital status, and education. When only normal birthweight infants were considered, the IMR, adjusted for maternal education level, was highest for infants born to unmarried black teens (9.5/1000 live births), followed by that for infants born to married black teens (9.1), unmarried black adults (7.5), married black adults (4.8), married white teens (4.4), married white adults (3.4), unmarried white adults (2.4), and unmarried white teens (1.3). When only low birthweight infants were considered, the highest IMR per 1000 was found in infants born to married black adults (119), followed by unmarried black adults (103), married black teens (99.9), unmarried black teens (92.5), married white adults (92.1), married white teens (79.0), unmarried white adults (38.0), and unmarried white teens (26.3). These differences led to a black-to-white IMR risk ratio from 1.3 for low birthweight infants born to unmarried teen or adult mothers to 3.7 for normal birthweight infants born to unmarried teen mothers.(ABSTRACT TRUNCATED AT 250 WORDS)

Geographic imbalances of physician supply: an international comparison.

This study was undertaken to compare geographic imbalances of physician manpower in developed and developing countries and to evaluate the success of policies designed to alleviate the imbalances. Data were drawn from a mail survey of countries conducted by the World Health Organization, from national statistical summaries, and from published information on national policies and programs. Information was available from 26 developing countries and 15 developed countries. Among developing countries, the degree of urbanization and rural economic development appeared to be the most important determinants of the level of geographic imbalance. Among developed countries, those with very high overall physician/population ratios tended to have the least degree of imbalance, but this effect was not consistent. At the national level in most countries, the effect of policies or programs specifically designed to redistribute physician manpower appeared to be limited.

A proposal to provide care to the uninsured through a network of community health centers.

While a national health insurance plan is needed, this alone will not provide access for approximately 30 million persons who face geographic, cultural, language, or health care system barriers, or who live in areas with provider shortages. These barriers often coexist with lack of insurance coverage, but they also affect millions who have public, or even private, coverage. Moreover, large segments of this population suffer from health problems not adequately addressed by the traditional medical model: teenage pregnancy, AIDS, injury, substance abuse, and the like. To provide appropriate care for these underserved persons, we propose to expand the existing network of community health centers over the next 10 years to a total of approximately 3,000. Such an expansion would provide a cost-effective approach to improving provider distribution, increasing consumer input, combining personal health services with health promotion, and removing both financial and nonfinancial barriers to care. This model can be implemented either independent of or in conjunction with other health care system reform efforts.

Cancer screening intervention among black women in inner-city Atlanta--design of a study.

This experimental study attempts to determine if an in-home educational intervention conducted by lay health workers (LHWs) can increase adherence among low-income, inner-city black women to schedules for screening for breast cancer and cervical cancer, as well as increase the women's knowledge and change their attitudes regarding these cancers. This paper is a description of the purposes, hypotheses, design, subject recruitment, intervention, and evaluation of the study conducted by Morehouse School of Medicine. Subjects were recruited from a variety of sources, including patients seen in a community health center, women referred by the National Black Women's Health Project (NBWHP), residents of public and senior citizen housing projects, and persons identified in various community settings. Fewer than half of those asked to participate agreed to do so. The 321 women who were recruited were demographically diverse. Overall, about half of these volunteer subjects self-reported at least one Papanicolaou (Pap) smear and one breast examination within a year before enrollment in the study. There was little variation by source of recruitment in compliance with screening recommendations, except that referrals from NBWHP were more likely (P less than 0.01) to have had a Pap test and breast self-examination, while residents of public housing projects were somewhat less likely to have done so. About 35 percent of participants ages 35 and older had a mammogram within an appropriate interval. Participants were randomly assigned to intervention and control groups. Women in the intervention group were visited in their homes by LHWs on three occasions; the LHWs provided education on cancer and reproductive health. The groups were comparable in their baseline sociodemographic status and previous screening history.
