Disagreement between patients' and general practitioners' estimates of patient health literacy increases from the top to the bottom of the social ladder: a cross-sectional study in the Paris area.

BACKGROUND: Associated with both socioeconomic position and health outcomes, health literacy (HL) may be a mechanism contributing to social disparities. However, it is often difficult for general practitioners (GPs) to assess their patients' HL level. OBJECTIVE: To analyse disagreements about patient HL between GPs and their patients according to the patient's socioeconomic position. METHODS: For each of the 15 participating GPs (from the Paris-Saclay University network), every adult consulting at the practice on a single day was recruited. Patients completed the European HL Survey questionnaire and provided socio-demographic information. For each patient, doctors answered 4 questions from the HL questionnaire with their opinion of the patient's HL. The doctor-patient disagreement about each patient's HL was analysed with mixed logistic models to study its associations with patients' occupational, educational, and financial characteristics. RESULTS: The analysis covered the 292 patients (88.2% of the 331 included patients) for whom both patients and GPs responded. The overall disagreement was 23.9%. In all, 71.8% of patients estimated their own HL as higher than their doctors did, and the gap between doctors' answers and those of their patients widened from the top to the bottom of the social ladder. The odd ratio for the 'synthetic disagreement' variable for workers versus managers was 3.48 (95% CI: 1.46-8.26). CONCLUSIONS: The lower the patient's place on the social ladder, the greater the gap between the patient's and doctor's opinion of the patient's HL. This greater gap may contribute to the reproduction or maintenance of social disparities in care and health.

Sex Differences in the Occurrence of Major Clinical Events in Elderly People with Type 2 Diabetes Mellitus Followed up in the General Practice.

AIMS: The main aim of the present work was to assess if sex influences the occurrence of major clinical events in elderly people with type 2 diabetes followed up in the primary care. METHODS: 983 subjects aged ≥65years with type 2 diabetes were included by 213 general practitioners and followed up prospectively for three years. Major clinical events were recorded every six month. The first endpoint was a composite of all-cause death and major vascular events (acute coronary syndrome, non-fatal stroke or transient ischemic attack, or revascularization for peripheral artery disease). The second endpoint was all-cause hospitalization. The occurrence of each endpoint was analyzed in order to estimate the role of sex and determine other predictors of major clinical events. RESULTS: At baseline, women were older than men but they had a lower prevalence of coexisting diseases (cardiovascular disease and cancer) and equivalent diabetes control (Glycated hemoglobin A1C: 6.9%±0.9 vs. 7.0%±1.1). Over the follow-up period, women were at lower risk to develop the composite endpoint (HR 0.60, 95% CI 0.40-0.91, p=0.016) and the hospitalization endpoint (OR 0.71, 95% CI 0.52-0.96, p=0.029). Coexisting diseases, functional ability and concomitant medications emerged as significant predictors of both endpoints. CONCLUSIONS: Elderly women with well-controlled type 2 diabetes were less likely to experience major clinical events than their male counterparts. More studies are needed to determine the reasons for the higher hospitalization rate in men.

Cardiovascular Disease in Type 2 Diabetes: A Review of Sex-Related Differences in Predisposition and Prevention.

Type 2 diabetes mellitus is a major risk factor for cardiovascular disease. However, compiled data suggest that type 2 diabetes affects the risk of cardiovascular disease differentially according to sex. In recent years, large meta-analyses have confirmed that women with type 2 diabetes have a higher relative risk of incident coronary heart disease, fatal coronary heart disease, and stroke compared with their male counterparts. The reasons for these disparities are not completely elucidated. A greater burden of cardiometabolic risk in women was proposed as a partial explanation. Indeed, several studies suggest that women experience a larger deterioration in major cardiovascular risk factors and put on more weight than do men during their transition from normoglycemia to overt type 2 diabetes. This excess weight is associated with higher levels of biomarkers of endothelial dysfunction, inflammation, and procoagulant state. Moreover, sex differences in the prescription and use of some cardiovascular drugs may compound an "existing" disparity. We searched PubMed for articles published in English and French, by using the following terms: ("cardiovascular diseases") AND ("diabetes mellitus") AND ("sex disparity" OR "sex differences" OR "sex related differences" OR "sex-related differences" OR "sex disparities"). In this article, we review the available literature on the sex aspects of primary and secondary prevention of cardiovascular disease in people with type 2 diabetes, in the predisposition to cardiovascular disease in those people, and in the control of diabetes and associated cardiovascular risk factors.

Gender-Related Differences in the Control of Cardiovascular Risk Factors in Primary Care for Elderly Patients With Type 2 Diabetes: A Cohort Study.

OBJECTIVE: The aim of this study was to estimate the association between gender and control of diabetes and other cardiovascular risk factors in elderly patients with type 2 diabetes mellitus. METHODS: The sujets âgés cohort is an observational study whose main objective was to describe the real-life management of elderly patients with type 2 diabetes mellitus in France. Nine hundred eighty-three patients with diabetes (517 men and 466 women) were recruited by 213 general practitioners and were followed up prospectively every 6 months for 3 years. Diabetes, hypertension and dyslipidemia were considered controlled if the glycated hemoglobin (A1C) was ≤7%, blood pressure was <140/90 mm Hg and low-density lipoprotein (LDL) cholesterol was ≤100 mg/dL. A1C levels and blood pressure measurements were recorded every 6 months for all patients. LDL cholesterol levels were optionally sampled every year. RESULTS: Women were older than men (77.3±5.72 vs. 76.1±6.01 years), more likely to be alone, less likely to be smokers/ex-smokers and less likely to have cardiovascular disease at baseline. Mean A1C levels of female patients (6.98%±1.03%) did not differ from those of male patients (6.91%±0.96%). Mean blood pressure measurements during follow up were not different between male and female patients. In contrast, female patients had significantly higher LDL cholesterol levels than male counterparts (105.2±32.6 vs. 94.9±29.1 mg/dL), regardless of statin therapy. CONCLUSION: Our results suggest no difference in the management of cardiovascular risk factors between elderly female patients with type 2 diabetes mellitus and their male counterparts, except for LDL cholesterol, which is significantly higher in women.

Are primary-care physician practices related to health behaviors likely to reduce social inequalities in health?

Our objective was to examine patients' health behaviors and the related practices of their primary-care physicians to determine whether physicians' actions might help to reduce the social inequalities in health behaviors among their patients. Fifty-two general practitioners, who were also medical school instructors in the Parisian area, volunteered to participate. A sample of 70 patients (stratified by sex) aged 40-70years was randomly chosen from each physician's patient panel and asked to complete a questionnaire about their social position and health behaviors: tobacco and alcohol use, diet, physical activity, and participation in breast and cervical cancer screening. Each physician reported their practices related to each such behavior of each patient. Mixed models were used to test for social differences. Questionnaires were collected in 2008-2009 from both patient and physician for 71% of the 3640 patients. Our results showed social inequalities disfavored those at the bottom of the social scale for all but one of the health behaviors studied among both men and women (exception: excessive alcohol consumption among women). Physicians' practices related to these health behaviors also appeared to be socially differentiated. Among men, this differentiation favored those with the lowest social position for all behaviors except physical activity. Among women, however, practices favored the most disadvantaged only for breast cancer screening. In all other cases, they were either socially neutral or unfavorable to the most disadvantaged. Physicians' practices related to their patients' health behaviors should focus more on those lowest in the social hierarchy, especially among women.

Time and feasibility of prevention in primary care.

BACKGROUND: Prevention is an essential task in primary care. According to primary care physicians (PCPs),lack of time is one of the principal obstacles to its performance. OBJECTIVE: To assess the feasibility of prevention in terms of time by estimating the time necessary to perform all of the preventive care recommended, separately from the PCPs and patient's perspectives, and to compare them to the amount of time available. METHODS: A review of the literature identified the prevention procedures recommended in France, the duration of each procedure and its recommended frequency, as well as PCPs' consultation time. A hypothetical patient panel size of 1000 patients, representative of the French population, served as the basis for our calculations of the annual time necessary for prevention for a PCP. The prevention time from the patient's perspective was estimated from data collected from a previous study of a panel of 3556 patients. RESULTS: For PCPs, the annual time necessary for all of the required preventive care was 250 hours, or 20% of their total patient time. For a patient, the annual time required for prevention during encounters with a PCP ranged from 9.7 to 26.4 minutes per year. The mean total encounter time was 75.9 minutes per year. Nearly 73% of patients had a prevention-to-care time ratio exceeding 15%. CONCLUSION: Feasibility thus differs substantially between patients. These differences correspond especially to disparities in the annual care time used by each patient. Specific solutions should be developed according to the patients' utilization of care.

Cardiovascular Drugs and Metformin Drug Dosage According to Renal Function in Non-Institutionalized Elderly Patients.

Adaptation of drug dosage to kidney function is a common problem in general practice. The aim was to describe adaptation of cardiovascular drugs and metformin according to renal function and its association with mortality with regard to metformin in a cohort of elderly patients. This was an ancillary study to the S.AGES cohort made up of patients over 65 years of age managed by their general practitioner under real-life conditions and followed up prospectively for 3 years. The medications studied were digoxin, spironolactone and metformin. Adaptation of their daily dose according to renal function (eGFR according to CKD/EPI) was compared to that recommended in the summaries of product characteristics (SPCs) or international scientific societies (ISS). A total of 900 patients were included, including 588 on metformin. At baseline, dose adjustment according to renal function was 100% and 87.6% (95% CI: 82.6-92.6) for patients on digoxin and spironolactone respectively. For metformin, only 71.3% (95% CI: 67.6-74.9) or 78.1% (95% CI: 74.7-81.4) of patients had their dosage adapted at inclusion according to their renal function depending on whether the SPCs or ISS recommendations were considered. During the 3-year follow-up period, 42/588 patients died (none from lactic acidosis). At inclusion, a metformin dosage not adapted for renal function according to ISS was not associated with an increase in all-cause mortality (OR 1.7; 95% CI 0.6-5.0, p = 0.32). In conclusion, approximately one-quarter of elderly patients treated with metformin do not have their dosage adapted for renal function according to ISS although there is no increase in mortality after follow-up for 3 years.

Association between Cardiovascular Drugs and Chronic Kidney Disease in Non-Institutionalized Elderly Patients.

Concern about the renal safety of commonly used cardiovascular drugs with demonstrated clinical benefit appears to be an obstacle to their use in the elderly. The objective was to describe the relationship between cardiovascular drugs and chronic kidney disease (CKD) in elderly individuals in the real-life setting. This is an ancillary study of the prospective non-interventional S.AGE (aged individuals) cohort. General physicians were free to prescribe any drug their patients needed. The participants were non-institutionalized patients aged 65 years and older treated by their primary physician for either chronic pain or atrial fibrillation or type 2 diabetes mellitus. The estimated glomerular filtration rate (eGFR) derived from the CKD-EPI formula was determined at inclusion and every year during 2 years of follow-up. This study comprised 2505 patients aged 77.8 ± 6.2 years. At inclusion, the factors associated with CKD (eGFR < 60 ml/min/1.73 m(2) ) in multivariate analysis were age, female gender, hypertension, heart failure, history of atherothrombotic disease and renin angiotensin system blockers, loop diuretics and calcium channel inhibitors. Introduction of each of these three drug classes during the follow-up period led to only a small decrease in the eGFR: -3.8 ± 12.7 (p < 0.0006), -2.2 ± 12.0 (p < 0.003) and -1.0 ± 13.4 ml/min./1.73 m(2) (NS), respectively. Only the introduction of loop diuretics was associated with CKD (OR 1.91, 95% CI: 1.25-2.90; p = 0.002). Renal safety of cardiovascular drugs in the elderly appears acceptable and should not be a barrier to their use.

Primary care management of non-institutionalized elderly diabetic patients: The S.AGES cohort - Baseline data.

AIM: S.AGES is a multicenter prospective cohort study of non-institutionalized patients aged 65 and over with atrial fibrillation, type 2 diabetes or chronic pain. Its objective is to describe the medical management in primary care. This article presents the baseline characteristics of subjects in the diabetes subcohort and compares the results to those from cohorts of older diabetic patients. METHODS: From April 2009 to June 2011, 983 patients were included in the diabetes subcohort by 213 primary care providers. Demographic data, geriatric parameters and the history, characteristics and treatment of the diabetes were recorded at baseline. RESULTS: The mean age was 76.7 ± 5.9 years. Most patients were living independently, with no cognitive impairment and in relatively good health. The duration of diabetes was 11.3 ± 8.7 years with average HbA1c of 6.9 ± 1.0%. 20% of patients had macrovascular disease, 33% renal failure, 14.6% ocular complication and 7.1% neuropathy. The first-line antidiabetic treatment was metformin (61.2%) and 18% of patients had used insulin. Treatment intensified with the worsening of diabetic symptoms. When compared to those from French and North American cohorts, the results showed increased complications and use of insulin with age, disease duration and severity. CONCLUSION: Due to the method of recruitment, S.AGES patients were generally healthy with well-controlled diabetes. However, the results were consistent with those from other cohorts. Three-year follow-up is expected to study the management of diabetic patients aged 65 and over in primary care.

Consequences of dextropropoxyphene market withdrawal in elderly patients with chronic pain.

OBJECTIVE: Describe the consequences of dextropropoxyphene (DXP) market withdrawal on analgesic prescriptions and on the quality of therapeutic management of chronic pain. PATIENTS AND METHODS: From a cohort of non-institutionalised elderly patients with chronic pain recruited by general practitioners, we selected patients who were treated with DXP daily for at least 6 months just prior to DXP market withdrawal and who had an evaluation of pain and its impact on daily activities before and after DXP withdrawal. RESULTS: One hundred three patients took DXP daily for chronic pain. Immediately after DXP market withdrawal, 42 (40.8%), 55 (53.4%) and 3 (2.9%) patients were treated with step 1, 2 and 3 analgesics, respectively, and 3 patients (2.9%) were no longer receiving any analgesic medication. Among the 55 patients who continued on step 2 analgesics, 37 were treated with tramadol, 14 with codeine and 9 with opium. Pain intensity and the impact of pain on daily activities remained stable. CONCLUSION: DXP market withdrawal had no consequences on the intensity or impact of chronic pain in elderly patients.

US adolescent nutrition, exercise, and screen time baseline levels prior to national recommendations.

Experts have recommended daily obesity prevention goals: ≥5 fruits/vegetables, <2 hours of screen time, >1 hour of physical activity, and no sugar-sweetened beverages (5-2-1-0). The authors analyzed National Health and Nutrition Examination Survey data for 1999-2002 to determine the proportion of US adolescents (12-19 years) who would have met each goal prior to dissemination of the 5-2-1-0 recommendations. Merely 0.4% would have met all goals; 41% would have met none. Only 9% consumed ≥5 fruits/vegetables, 27% reported <2 hours of screen time, 32% had >1 hour of physical activity, and 14% consumed no sugar-sweetened beverages per day. Demographic subgroups (eg, racial/ethnic minority and lower income) would have been even farther from meeting the goals. Clinicians are likely to encounter adolescents with nutrition, exercise, and screen time behaviors that are far from 5-2-1-0 goals, and can use these guidelines during clinical encounters to counsel adolescents regarding healthier lifestyles.

Nutrient intake and performance during a mountain marathon: an observational study.

In order to study nutrient intake of amateur runners during a mountain marathon, compliance with recommendations, and association with performance, an intake of 42 participants in a Swiss mountain marathon was assessed by direct observation. Data on demographics, dietary preparation and race experience were obtained by questionnaires. Anthropometrical measures were performed before and after the race. Mean hourly intakes (SD) of fluid, carbohydrate, energy and sodium were 545 (158) ml, 31 (14) g, 141 (63) kcal [or 590 (264) kJ], and 150 (203) mg respectively. A third of the runners drank 600 ml h(-1) or more, 52% consumed less than 30 g h(-1 )carbohydrates, 95% consumed less than 500 mg h(-1) sodium. Mean weight loss was 4 (1.5) kg; 30 runners (71%) lost over 3% body mass. Mean running time was 7 h 3 min (1 h 17 min). Most participants failed to meet nutritional recommendations. None were at risk of overhydration. Body composition and race experience were correlated with performance, but not nutrient intake. Because experienced runners are well trained, fitter, and know better their personal needs during such a race, it is difficult to disentangle these associations. As causal relationship cannot be proven with this cross-sectional design, non-compliance with intake recommendations requires additional experimental research on the impact of nutrient intake on field performance.
