Systemic antibiotics and tooth loss in periodontal disease.

Systemic antibiotics have been recommended for the treatment of destructive periodontal disease. Our goal was to relate antibiotic use for medical or dental reasons to subsequent tooth loss in a cohort of 12,631 persons with destructive periodontal disease. After adjustment for age, smoking, and other confounders, the dispensing of antibiotics for 1-13 days, 14-20 days, or 21 or more days was not associated with reduced tooth loss [Adjusted rate ratio (RR) = 1.0; 95% Confidence Interval (CI) = 0.8-1.1; RR = 1.2; 95% CI = 0.9-1.4, and RR =1.2, 95% CI =1.0-1.3, respectively]. Numerous subgroup analyses were consistent with these overall null findings, with two exceptions: Longer courses of tetracyclines were associated with reduced tooth loss among persons receiving periodontal care, and penicillin was associated with reduced tooth loss among persons with more severe disease. Long-term, larger randomized trials are needed to provide evidence that antibiotics reduce tooth loss when used in the management of destructive periodontal disease.

Statin use and tooth loss in chronic periodontitis patients.

BACKGROUND: Statins have anti-inflammatory and bone stimulating properties that may positively affect chronic periodontitis. Our objective in this study was to evaluate whether statin use by chronic periodontitis patients had a beneficial impact on tooth loss. METHODS: In a retrospective cohort study (N patients = 1,021; mean follow-up = 7.1 years), dental records were merged with pharmacy data. Any statin use during 3 years, statin use during each of 3 consecutive years (regular use), and any statin use during the first 3 years after the initial periodontal exam were evaluated as predictors of tooth loss using negative binomial regression models with adjustment for potential confounding factors. RESULTS: Any statin use during 3 years was not associated with tooth loss rate in the year subsequent to the 3-year period (rate ratio [RR] = 1.00; 95% confidence interval [CI] = 0.56 to 1.81). Regular statin use during 3 years was associated with a non-significant 37% reduced tooth loss rate in the year subsequent to the 3-year period (RR = 0.63; 95% CI = 0.32 to 1.25). Any statin use during the first 3 years after the initial periodontal exam was associated with a 48% decreased tooth loss rate in year 4 and subsequent years (RR = 0.52; 95% CI = 0.29 to 0.95). CONCLUSIONS: Our findings were mixed for an association of statin use with reduced tooth loss in chronic periodontitis patients. Lack of control for some potential confounders, particularly smoking, and evaluation of different patterns of statin usage hamper the interpretation of the results. Exploration of these findings in additional epidemiological studies may be worthwhile.

Racial/ethnic inequities in continuity and site of care: location, location, location.

OBJECTIVE: To examine how continuity of care with the same provider varies by race/ethnicity and by site of care. DATA SOURCES/STUDY SETTING: Secondary data analyses of the 1996-97 Community Tracking Study household survey, a representative cross-sectional sample of 34,858 U.S. adults (aged 18 to 64 years), were employed. STUDY DESIGN: Logistic regression analyses were conducted to explore relationships between respondents' race/ethnicity and having a regular site of care, type of site, and continuity with the same provider at this site. PRINCIPAL FINDINGS: Racial/ethnic minority group members were less likely than whites to identify a regular site of care. Among respondents who identified a regular site, minorities, particularly Spanish-speaking Hispanics, reported less continuity of care with the same provider. However, these disparities in continuity were largely explained by racial/ethnic differences in the types of places where care was obtained. Compared to those who were seen in physicians' offices, continuity with the same provider was much lower among respondents who were seen in hospital out patient departments or health centers or other clinics. CONCLUSIONS: Racial and ethnic minority group members receive less continuity of care for reasons including lack of a regular site of care and less continuity with the same provider. Greater use of hospital clinics and community health centers by minorities also contributes to this discontinuity.

Racial and ethnic disparities in perceptions of physician style and trust.

CONTEXT: While pervasive racial and ethnic inequalities in access to care and health status have been documented, potential underlying causes, such as patients' perceptions of their physicians, have not been explored as thoroughly. OBJECTIVE: To assess whether a person's race or ethnicity is associated with low trust in the physician. DESIGN, SETTING, AND PARTICIPANTS: Data were obtained from the 1996 through 1997 Community Tracking Survey, a nationally representative sample. Adults who identified a physician as their regular provider and had at least 1 physician visit in the preceding 12 months were included (N = 32,929). MAIN OUTCOME MEASURE: Patients' ratings of their satisfaction with the style of their physician and their trust in physicians. The Satisfaction With Physician Style Scale measured respondents' perceptions of their physicians' listening skills, explanations, and thoroughness. The Trust in Physician Scale measured respondents' perceptions that their physicians placed the patients' needs above other considerations, referred the patient when needed, performed unnecessary tests or procedures, and were influenced by insurance rules. RESULTS: After adjustment for socioeconomic and other factors, minority group members reported less positive perceptions of physicians than whites on these 2 conceptually distinct scales. Minority group members who lacked physician continuity on repeat clinic visits reported even less positive perceptions of their physicians on these 2 scales than whites. CONCLUSIONS: Patients from racial and ethnic minority groups have less positive perceptions of their physicians on at least 2 important dimensions. The reasons for these differences should be explored and addressed. Arch Fam Med. 2000;9:1156-1163

Physicians' advice to quit smoking. The glass remains half empty.

BACKGROUND: We explored the relationships between advice from a physician to quit smoking and an array of respondents' characteristics, including sociodemographic factors, health status, health insurance status, physician continuity, and intensity of smoking. METHODS: We examined data from the nationally representative 1996-1997 Community Tracking Study Household Survey. We used multivariate logistic regression to model receipt of cessation advice in a sample of 8229 smokers aged 18 years and older who made at least one visit to a physician in the past year. RESULTS: Less than 50% of the subjects reported receiving cessation advice. Advice was less likely for patients who were younger, men, African American, uninsured, healthier, lower health care services users, or lighter smokers, and more likely for those with military health insurance, who attended hospital outpatient clinics, or who belonged to health maintenance organizations. CONCLUSIONS: Physicians continue to miss opportunities to provide smoking cessation advice, a potentially lifesaving intervention. Given the adverse health consequences of tobacco use and the demonstrated benefit of advice to quit, physicians need to improve their cessation counseling efforts.

To buy, or not to buy: factors associated with the purchase of nongroup, private health insurance.

BACKGROUND: Employment-based health insurance coverage is declining in the United States. Many recent efforts to increase coverage have promoted the individual purchase of insurance, with or without subsidies. OBJECTIVES: To study the associations of factors including minority group membership, education, income, wealth, and health status with the voluntary purchase of nongroup, private health insurance. DESIGN: Analysis of the 1987 National Medical Expenditure Survey (NMES). SUBJECTS: Adult respondents to the NMES who were younger than 65 years of age in 2,574 health-insurance eligibility units (HIEUs) and who either were uninsured or who purchased nongroup, private health insurance for all of 1987. MEASURES: Adjusted odds ratios and marginal effects for the associations of minority group membership, educational attainment, income, and wealth with the purchase of nongroup insurance. RESULTS: Lower-income and less-wealthy HIEUs were much less likely to purchase insurance than higher-income and wealthier HIEUs, with income and wealth measures having relatively independent effects. With simultaneous adjustment for income, wealth, and other factors, members of minority groups had less than half the odds of non-Hispanic whites and persons with less than a high school education had less than half the odds of college graduates of purchasing nongroup insurance. CONCLUSIONS: Minorities and the less educated are much less likely to buy their own health insurance, even after adjustment for income and wealth. Programs encouraging the voluntary purchase of health insurance are likely to widen coverage gaps between historically disadvantaged groups and others.

Is family care associated with reduced health care expenditures?

BACKGROUND: Specific components of family medicine associated with reduced health care costs are not well understood. We examined whether people who received "family care," the sharing of a personal physician across familial generations, had lower health care expenditures than those who received "individual care" that lacked generational continuity. METHODS: We studied 1728 children and 2543 adults using a data subset of the 1987 National Medical Expenditure Survey, a representative sample of the civilian noninstitutionalized US population, to examine the relationship between care category and total health care expenditures, adjusting for potential confounders and effect modifiers. Survey respondents from households with either a married or a single woman aged 18 to 55 years as head of household and at least 1 child younger than 18 years were included. Only individuals reporting a family physician (FP) or general practitioner (GP) as their personal doctor were examined, since intergenerational family care is provided almost exclusively by FPs and GPs. RESULTS: Family care provided by an FP or GP was associated with 14% lower expenditures for adults ($51), after adjustment for covariates (P = .04), compared with individual care provided by a family or general practitioner. Although not statistically significant, for children family care was associated with 9% lower expenditures ($19). CONCLUSIONS: These findings suggest that family care provided by FPs or GPs is associated with lower health care costs. Policies promoting family care may reduce health care costs.

Use of hormone replacement therapy in Washington State: is prevention being put into practice?

BACKGROUND: American women are using hormone replacement therapy (HRT) for long-term disease prevention, as well as symptom control, in increasing numbers. Our study examined the role of prevention in women's decisions to initiate HRT and their intended duration of therapy. METHODS: We analyzed the mailed survey responses of 2023 women aged 50 to 70 years from the practices of 46 physicians in the Puget Sound region for knowledge and attitudes about HRT, current use, and intended duration of therapy. Multiple logistic regression was used to model current HRT use and intended treatment length. RESULTS: A total of 71% of our respondents were using HRT. Women with osteoporosis, coronary heart disease (CHD), or risk factors for CHD were not more likely to be using HRT, and women with CHD or risk factors for CHD were not targeted by their physicians for discussion of HRT. Of women using HRT, 77% expected lifelong use, and this was not more common among women initiating HRT for disease prevention. CONCLUSIONS: Despite the high rates of HRT use and expected lifelong duration, use of HRT for prevention was neither higher among women most likely to benefit nor a major determinant of expected lifetime use.

Attitudes toward menopause and hormone therapy among women with access to health care.

OBJECTIVE: To explore the relationship between women's attitudes toward menopause and hormone therapy and paradigms of menopause as a natural life event versus a biomedical phenomenon. DESIGN: Women (N = 2092) sampled from physicians' practices in Washington state completed mailed questionnaires with a response rate of 72%. RESULTS: Women's attitudes toward menopause were unrelated to their adoption of a biomedical versus developmental paradigm of menopause. In contrast, women's adoption of the view that menopause was an endocrine deficiency and that symptoms should be treated with hormones were correlated. Endorsement of the endocrine deficiency model of menopause was related to women's attitudes toward hormone therapy as more efficacious, less risky, and requiring daily use of a drug. Women's experiences of a hysterectomy and hormone use were associated with their attitudes. CONCLUSIONS: Women's attitudes toward menopause are multidimensional and not influenced wholly by adoption of a biomedical or developmental paradigm. Women embraced menopause as part of life and simultaneously accepted changes in their endocrine production. Attitudes toward hormone therapy were closely aligned with adoption of a biomedical view of menopause and use of hormone therapy.

Deciding about hormone therapy: validation of a model.

OBJECTIVE: The purposes of this study were to (1) validate components of a decision process regarding adoption of hormone therapy and (2) compare the decision processes women used with respect to their evaluation of decision quality. DESIGN: A sample of women participating in a population-based study of midlife women's health participated in individual in-depth interviews. RESULTS: Content analysis of 30 recorded interviews provided evidence that each component of the decision process (precontemplation, contemplation, commitment, critical evaluation, and continuance) was replicated. Few additional codes were identified, and these could be subsumed under the phases of the original decision model. CONCLUSIONS: Women's self-reported statuses on a screening questionnaire corresponded to the stages of the decision model coded from their interviews. What women actually decided to do (use hormone therapy or something else) was not associated with their decision process. Satisfaction with the decision, uncertainty about the decision, and other factors related to the decision were independent of the decision phases.

Do physicians do as they say? The case of mammography.

OBJECTIVE: To assess the utility of survey-based physician policy in predicting actual mammography ordering behavior, as measured by medical record abstraction. DESIGN: Cross-sectional survey of practicing community physicians. Responses were correlated with data abstracted from the medical records of patients in the practices of the participating physicians. PARTICIPANTS: Family and general practitioners in Washington State. Medical records of female patients aged 40 to 80 years provided data on actual mammography performance. MAIN OUTCOME MEASURES: The proportions of female patients aged 40 to 49 and 50 to 80 years who had received a screening mammogram within the previous 2 years. RESULTS: Of the more than 100 potential predictors available, only 4 were significantly associated with screening rates for women younger than 50 years and only 3 were associated with screening rates for older women. Regression models explained only 21% to 25% of the variance in screening rates. Physician estimates of screening rates were poorly correlated with actual screening rates. CONCLUSIONS: Practicing physicians do not know how well they screen their patients using mammography. Extensive survey data, including direct estimates of behavior, demographics, policy measures, and case scenario responses, were of limited use in predicting actual screening rates. Our results underscore the importance of using data rather than proxy measures to study physician performance.

Physician policies on the use of preventive hormone therapy.

BACKGROUND: Current guidelines recommend that most postmenopausal women be offered preventive hormone therapy (PHT), but there have been no surveys of U.S. physicians' policies since these guidelines appeared. We sought to measure physicians' policies and attitudes about PHT and compare them with the American College of Physicians' guideline on the use of PHT. METHODS: We used a stratified, randomized survey of gynecologists, family physicians, and general internists in Washington, Alaska, Montana, and Idaho. RESULTS: Nearly all respondents reported strong belief in the benefits of PHT and felt that the vast majority of their patients should be offered PHT. Where they differed, gynecologists believed even more strongly in its benefits than other respondents. Physicians estimated that 3% of their patients with a uterus were on regimens without any progestin and 23% were on regimens including time without any hormones. Gynecologists ranked mammography first and PHT use second on a list of eight preventive services, while the other respondents ranked smoking cessation first and PHT fourth (P < .0001 for differences). CONCLUSIONS: Among surveyed physicians, there was near unanimous adoption of policies favoring the recommendation of PHT. Gynecologists believed in it even more strongly than family physicians and general internists and ranked it as more important than counseling about smoking cessation.
