The role of organization of care in GPs' prevention practice.

BACKGROUND: General practitioners (GPs) do not systematically include preventive recommendations in their practice, and some characteristics of health care organization are associated with more systematic prevention. But the characteristics of health care organization may act in a nonuniform manner depending on the type of preventive care. Thus, one characteristic can be positively associated with one type of preventive care and negatively associated with another. Our aim was to investigate the association between health care organization in general practice and different areas of preventive care (immunization and addiction prevention), in search of nonuniform associations. METHODS: We used a representative survey of 1,813 French GPs conducted in 2009. Four preventive care practices were studied: immunization through flu and HPV vaccination, and prevention of addictive behaviors concerning tobacco and alcohol use.Characteristics of GPs' health care organization and the social context of their practice were collected (spatial accessibility to GPs and socioeconomic level of the area of practice). We constructed mixed models to study associations and interactions between the organization variables and preventive care. RESULTS: Four out of five characteristics of GPs' organization have uneven impacts on different types of preventive care (p-interaction < 10-4). For example, number of daily consultations is associated with better immunization prevention but with poorer prevention counseling in addictive behaviors. In contrast, working with digital medical files is uniformly associated with both types of preventive care (OR = 1.29 [1.15-1.45]; P < 10-4). CONCLUSION: An approach centered on specific types of preventive care should help deepen our understanding of prevention and possibly help to identify a new typology for preventive care.

Visit-to-Visit Blood Pressure Variability Is Associated With Cognitive Decline and Incident Dementia: The S.AGES Cohort.

To investigate the impact of visit-to-visit systolic blood pressure variability (BPV), diastolic BPV, mean arterial pressure variability, and pulse pressure variability on cognitive decline and incident dementia in noninstitutionalized patients aged ≥65 years. A total of 3319 subjects from the S.AGES (Sujets AGÉS-Aged Subjects) cohort underwent clinical examinations every 6 months during 3 years. Variability was evaluated using standard deviation (SD), coefficient of variation, average real variability, successive variation, variation independent of mean, and residual SD. Cognition was assessed using the Mini-Mental State Examination and dementia with the Diagnostic Statistical Manual of Mental Disorders. Linear mixed models and Cox proportional hazards models were used. Higher systolic BPV was associated with poorer cognition independently of baseline SBP: adjusted 1-SD increase of coefficient of variation: ß (SE)=-0.12 (0.06), P=0.04. Similar results were observed for diastolic BPV and mean arterial pressure variability: ß (SE)=-0.20 (0.06), P<0.001 for both. Higher pulse pressure variability was no longer associated with cognitive function after adjustment for age, except with residual SD (P=0.02). Among the 3319 subjects, 93 (2.8%) developed dementia. Higher systolic BPV was associated with greater dementia risk (adjusted 1-SD increase of coefficient of variation: hazard ratios=1.23 [95% CI, 1.01-1.50], P=0.04). Similar results were found for diastolic BPV and mean arterial pressure variability (P<0.01). Pulse pressure variability was not associated with dementia risk. Beyond hypertension, higher BPV is a major clinical predictor of cognitive impairment and dementia. Further studies are needed to assess whether controlling BP instability could be a promising interventional target in preserving cognition among older adults.

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.

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.

What role does the general practitioner in France play among cancer patients during the initial treatment phase with intravenous chemotherapy? A qualitative study.

BACKGROUND: France's ethical and legal principles place general practitioners (GPs) at the forefront of cancer patient management, coordination, and follow-up. The objective of this study was to determine the actual role of GPs in the follow-up phase as well as patient perspectives on their GPs. METHOD: A multidisciplinary group of researchers conducted this qualitative study based on in-depth interviews of 50 patients managed at two cancer centres. A content analysis method was used to analyse the study data. RESULTS: According to the patients interviewed for this study, their GPs were relatively ineffective at managing medical problems related to cancer by comparison with their oncologists. Nonetheless, the patients had all consulted their GPs during the interval between the diagnosis and our interview. Reasons given for consulting their GPs included administrative matters, psychological support, reassurance, and advice, but also to a lesser extent, medical management. CONCLUSION: Patients' perspectives called attention to two aspects of the role of GPs in the French healthcare system: (a) the importance of GPs within an effective system for managing cancer patients, and (b) for some patients, GPs' relative lack of medical skill compared to oncologists.

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.

Predicting falls in elderly patients with chronic pain and other chronic conditions.

BACKGROUND: The aim was to identify fall predictors in elderly suffering from chronic pain (CP) and to test their applicability among patients with other chronic conditions. METHODS: 1,379 non-institutionalized patients aged 65 years and older who were suffering from CP (S.AGE CP sub-cohort) were monitored every 6 months for 1 year. Socio-demographic, clinical and pain data and medication use were assessed at baseline for the association with falls in the following year. Falls were assessed retrospectively at each study visit. Logistic regression analyses were performed to identify fall predictors. The derived model was applied to two additional S.AGE sub-cohorts: atrial fibrillation (AF) (n = 1,072) and type-2 diabetes mellitus (T2DM) (n = 983). RESULTS: Four factors predicted falls in the CP sub-cohort: fall history (OR: 4.03, 95 % CI 2.79-5.82), dependency in daily activities (OR: 1.81, 95 % CI 1.27-2.59), age ≥75 (OR: 1.53, 95 % CI 1.04-2.25) and living alone (OR: 1.73, 95 % CI 1.24-2.41) (Area Under the Curve: AUC = 0.71, 95 % CI 0.67-0.75). These factors were relevant in AF (AUC = 0.71, 95 % CI 0.66-0.75) and T2DM (AUC = 0.67, 95 % CI 0.59-0.73) sub-cohorts. Fall predicted probability in CP, AF and T2DM sub-cohorts increased from 7, 7 and 6 % in patients with no risk factors to 59, 66 and 45 % respectively, in those with the four predictors. Fall history was the strongest predictor in the three sub-cohorts. CONCLUSION: Fall history, dependency in daily activities, age ≥75 and living alone are independent fall predictors in CP, AF and T2DM patients.

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.

National observatory on the therapeutic management in ambulatory care patients aged 65 and over, with type 2 diabetes, chronic pain or atrial fibrillation.

The primary objective of the S.AGES cohort is to describe the real-life therapeutic care of elderly patients. Patients and methods. This is a prospective observational cohort study of 3 700 non-institutionalized patients over the age of 65 years with either type 2 diabetes mellitus (T2DM), chronic pain or atrial fibrillation (AF) recruited by French general practitioners (GPs). Follow-up is planned for 3 years. Baseline characteristics. In the chronic pain sub-cohort, 33% of patients are treated with only grade 1 analgesics, 29% with grade 2 analgesics and 3% with grade 3 analgesics, and 22% have no pain treatment. In the T2DM sub-cohort, 61% of patients have well-controlled diabetes (Hb1c<7%) and 18% are treated with insulin. In the AF sub-cohort, 65% of patients have a CHADS2 score greater than 2, 77% are treated with oral anticoagulants, 17% with platelet inhibitors, 40% with antiarrhythmic drugs and 56% with rate slowing medications. Conclusion. The S.AGES cohort presents a unique opportunity to clarify the real-life therapeutic management of ambulatory elderly subjects and will help to identify the factors associated with the occurrence of major clinical events.

[Acute fever: has the media coverage of the swine flu generated a medical overconsumption in primary care in France?]. / Etat fébrile: la médiatisation de la grippe A(H1N1)v a-t-elle généré une surconsommation médicale en médecine générale? Etude prospective utilisant un questionnaire informatisé accessible en ligne.

OBJECTIVE: Based on patient's declarations, evaluate if the media coverage of the pandemic flu (H1N1) has lead to an overconsumption of primary care. Identify the opinions of the general practionners (GP) concerning this media coverage and the health crisis. METHODS: A prospective study, based on an electronic questionnaire, was conducted during the main period of the pandemic flu. Each GP was invited to include one patient who presented fever since less than 2 days, associated to two of four following clinical signs: cough, headache, coat throat and ache. RESULTS: 730 questionnaires were fully completed and analyzed. 96 patients (12,9%) have declared to the GP an overconsumption, and two thirds of them because of their concern about the swine flu and a quarter because the social control. This concern was noted by 80% of the GP from the beginning of the flu 77% of the GP have considered the media coverage of the flu alarming, while 69% of them have declared to feel serene concerning the pandemic. No statistic link has been noticed between the GP opinions and the overconsumption of their patients. DISCUSSION: Media coverage of the swine flu and the state organization of the crisis have lead to an overconsumption estimated to 13%. Many efforts must be done in the future to reassure patients about flu and its vaccination.
