Mortality and Vascular Morbidity in Older Adults With Asymptomatic Versus Symptomatic Peripheral Artery Disease

Background— Our aim was to assess the mortality and vascular morbidity risk of elderly individuals with asymptomatic versus symptomatic peripheral artery disease (PAD) in the primary care setting. Methods and Results— This prospective cohort study included 6880 representative unselected patients ≥65 years of age with monitored follow-up over 5 years. According to physician diagnosis, 5392 patients had no PAD, 836 had asymptomatic PAD (ankle brachial index <0.9 without symptoms), and 593 had symptomatic PAD (lower-extremity peripheral revascularization, amputation as a result of PAD, or intermittent claudication symptoms regardless of ankle brachial index). The risk of symptomatic compared with asymptomatic PAD patients was significantly increased for the composite of all-cause death or severe vascular event (myocardial infarction, coronary revascularization, stroke, carotid revascularization, or lower-extremity peripheral vascular events; hazard ratio, 1.48; 95% confidence interval, 1.21 to 1.80) but not for all-cause death alone (hazard ratio, 1.13; 95% confidence interval, 0.89 to 1.43), all-cause death/myocardial infarction/stroke (excluding lower-extremity peripheral vascular events and any revascularizations; hazard ratio, 1.18; 95% confidence interval, 0.92 to 1.52), cardiovascular events alone (hazard ratio, 1.20; 95% confidence interval, 0.89 to 1.60), or cerebrovascular events alone (hazard ratio, 1.33; 95% confidence interval, 0.80 to 2.20). Lower ankle brachial index categories were associated with increased risk. PAD was a strong factor for the prediction of the composite end point in an adjusted model. Conclusions— Asymptomatic PAD diagnosed through routine screening in the offices of primary care physicians carries a high mortality and/or vascular event risk. Notably, the risk of mortality was similar in symptomatic and asymptomatic patients with PAD and was significantly higher than in those without PAD. In the primary care setting, the diagnosis of PAD has important prognostic value.

Evaluation of a structured treatment and teaching programme on hypertension in general practice

OBJECTIVE Evaluation of a structured hypertension treatment and teaching programme in general practice. DESIGN Prospective controlled trial; follow-up period 18 months. SETTING 10 primary health care practices. PRACTICES AND PATIENTS: From each practice 20 patients (30 to 60 years old, mean of the last two blood pressure measurements at or above 160 and/or 95 mmHg) were randomly selected; in 5 practices these patients were to participate in the treatment and teaching programme; in the remaining 5 practices hypertension care was continued without the availability of such a programme (controls). INTERVENTION Structured treatment and teaching programme based upon four group sessions for patients mainly conducted by paramedical personnel. MAIN OUTCOME MEASURES Blood pressure, body weight, prescription of antihypertensive drugs - as documented in the patients records. MAIN RESULTS Of the 100 control patients 26 and of the 100 intervention patients 14 were lost to observation; 46 patients had agreed to participate in the programme. The mean number of prescribed antihypertensive agents per patient decreased in the intervention group (1.8 +/- 1.3 at baseline, vs 1.2 +/- 1.2 at follow-up) compared to the control group (1.6 +/- 1.3 vs 1.8 +/- 1.6); difference 0.8 (95% CI 0.4 to 1.1), p < 0.0001. In the control group 9% and in the intervention group 33% of patients had documented reductions of body weight (p < 0.0001). Blood pressure decreased in the intervention group (162 +/- 14/100 +/- 7 mmHg at baseline, vs 154 +/- 16/95 +/- 9 mmHg at follow-up) compared to the control group (161 +/- 13/98 +/- 7 mmHg vs 158 +/- 18/96 +/- 11 mmHg); differences for systolic blood pressure 5 (95% CI 0 to 10) mmHg, p = 0.071; for diastolic blood pressure 4 (1 to 7) mmHg, p = 0.018. CONCLUSIONS The introduction of a structured hypertension treatment and teaching programme in general practice may lead to significant improvements of hypertension care.

Birth weight of children with congenital heart disease

Birth weights of 843 children with congenital heart disease (CHD) were compared to the respective data of a normal West German population. On average, the CHD group had significantly lower birth weights, but the weight deficit was far less pronounced than in previous studies. The decrease in birth weight was distinct only in children with tetralogy of Fallot and atrial septal defect. Compared to normal newborns, patients with CHD were more often small for gestational age (15.0%) or had a low (<2500 g) birth weight (8.6%). The prevalence of prematurity was not increased. Extracardiac malformations were not significantly more common in CHD patients, who were small for gestational age, than in CHD patients with normal birth weight.

Patients with femoral or distal forearm fracture in Germany: a prospective observational study on health care situation and outcome

BackgroundDistal radius and proximal femoral fractures are typical injuries in later life, predominantly due to simple falls, but modulated by other relevant factors such as osteoporosis. Fracture incidence rates rise with age. Because of the growing proportion of elderly people in Western industrialized societies, the number of these fractures can be expected to increase further in the coming years, and with it the burden on healthcare resources. Our study therefore assessed the effects of these injuries on the health status of older people over time. The purpose of this paper is to describe the study method, clinical parameters of fracture patients during hospitalization, mortality up to one and a half years after discharge in relation to various factors such as type of fracture, and to describe changes in mobility and living situation.MethodsData were collected from all consecutive patients (no age limit) admitted to 423 hospitals throughout Germany with distal radius or femoral fractures (57% acute-care, femoral and forearm fractures; 43% rehabilitation, femoral fractures only) between January 2002 and September 2003. Polytrauma and coma patients were excluded. Demographic characteristics, exact fracture location, mobility and living situation, clinical and laboratory parameters were examined. Current health status was assessed in telephone interviews conducted on average 6–7 months after discharge. Where telephone contact could not be established, at least survival status (living/deceased/date of death) was determined.ResultsThe study population consisted of 12,520 femoral fracture patients (86.8% hip fractures), average age 77.5 years, 76.5% female, and 2,031 forearm fracture patients, average age 67.6 years, 81.6% female. Womens average age was 6.6 (femoral fracture) to 10 years (forearm fracture) older than mens (p < 0.0001). Only 4.6% of femoral fracture patients experienced changes in their living situation post-discharge (53% because of the fracture event), although less than half of subjects who were able to walk without assistive devices prior to the fracture event (76.7%) could still do so at time of interview (34.9%). At time of interview, 1.5% of subjects were bed-ridden (0.2% before fracture). Forearm fracture patients reported no change in living situation at all. Of the femoral fracture patients 119 (0.95%), and of the forearm fracture patients 3 (0.15%) died during hospital stay. Post-discharge (follow-up one and a half years) 1,463 femoral fracture patients died (19.2% acute-care patients, 8.5% rehabilitation patients), but only 60 forearm fracture patients (3.0%). Ninety percent of femoral fracture deaths happened within the first year, approximately 66% within the first 6 months. More acute-care patients with a pertrochanteric fracture died within one year post-discharge (20.6%) than patients with a cervical fracture (16.1%).ConclusionMortality after proximal femoral fracture is still alarmingly high and highest after pertrochanteric fracture. Although at time of interview more than half of femoral fracture patients reported reduced mobility, most patients (96%) attempt to live at home. Since forearm fracture patients were on average 10 years younger than femoral fracture patients, forearm fractures may be a means of diagnosing an increased risk of later hip fractures.

Prevalence of anemia in elderly patients in primary care: impact on 5-year mortality risk and differences between men and women

ABSTRACT Background: Increased mortality in patients with anemia has been demonstrated in disabled, seriously ill or hospitalized patients. In industrialized nations with their aging societies, however, elderly but apparently healthy family-physician patients are an important demographic group from a public-health perspective. We therefore set out to evaluate the prevalence of anemia in this group and associations between anemia and 5-year all-cause mortality, adjusted for multiple other established risk factors and chronic diseases. Methods: This was a monitored, prospective cohort study in Germany with 344 representative family physicians who documented, consecutively, elderly patients (aged ≥ 65 years). Extensive fasting plasma parameters were collected at baseline. Anemia at inclusion was defined according to World Health Organization criteria (hemoglobin below 12 g/dl in women and 13 g/dl in men). All participants were followed up for death of any cause for 5.3 years. Results: Among the 6880 individuals, 2905 men and 3975 women, aged 65–95 (mean age 72.5), mild anemia (hemoglobin levels ≥10 g/dl) was found in 6.1% of women and 8.1% of men. Among those patients, 36.1% of anemic men and 15.0% of anemic women died. In a Cox proportional hazards analysis, multiple adjusted for potential confounders including major comorbidities, a near doubling of the 5-year mortality risk in anemic men (hazard ratio [HR] 1.9; 95% confidence interval [CI] 1.5–2.4) was found, while in anemic women there was no risk increase at all (HR 1.1; 95% CI 0.8–1.6). Even if patients with the lowest hemoglobin concentration (<11 g/dl for women, <12 g/dl for men) are singled out for multiple-adjusted analysis, anemia in men was related to a significant mortality risk (HR 3.3; 95% CI 2.1–5.1), but not in women (HR 1.85; 95% CI 0.97–3.53). Conclusion: In typical elderly patients without severe comorbidities, mild anemia was significantly associated with greater mortality in men but not in women. Given the impact of sex on outcomes of older subjects with mild anemia, the current definition of anemia should be adjusted for elderly males towards a higher hemoglobin threshold. Interventional trials will be needed to determine whether a consistent correction of anemia improves mortality of older men.

Randomised controlled comparison of the Health Survey Short Form (SF-12) and the Graded Chronic Pain Scale (GCPS) in telephone interviews versus self-administered questionnaires. Are the results equivalent?

BackgroundThe most commonly used survey methods are self-administered questionnaires, telephone interviews, and a mixture of both. But until now evidence out of randomised controlled trials as to whether patient responses differ depending on the survey mode is lacking. Therefore this study assessed whether patient responses to surveys depend on the mode of survey administration. The comparison was between mailed, self-administered questionnaires and telephone interviews.MethodsA four-armed, randomised controlled two-period change-over design. Each patient responded to the same survey twice, once in written form and once by telephone interview, separated by at least a fortnight. The study was conducted in 2003/2004 in Germany. 1087 patients taking part in the German Acupuncture Trials (GERAC cohort study), who agreed to participate in a survey after completing acupuncture treatment from an acupuncture-certified family physician for headache, were randomised. Of these, 823 (664 women) from the ages of 18 to 83 (mean 51.7) completed both parts of the study. The main outcome measure was the comparison of the scores on the 12-Item Short-Form Health Survey (SF-12) and the Graded Chronic Pain Scale (GCPS) questionnaire for the two survey modes.ResultsComputer-aided telephone interviews (CATI) resulted in significantly fewer missing data (0.5%) than did mailed questionnaires (2.8%; p < 0.001). The analysis of equivalence revealed a difference between the survey modes only for the SF-12 mental scales. On average, reported mental status score was 3.5 score points (2.9 to 4.0) lower on the self-administered questionnaire compared to the telephone interview. The order of administration affected results. Patients who responded to the telephone interview first reported better mental health in the subsequent paper questionnaire (mean difference 2.8 score points) compared to those who responded to the paper questionnaire first (mean difference 4.1 score points).ConclusionDespite the comparatively high cost of telephone interviews, they offer clear advantages over mailed self-administered questionnaires as regards completeness of data. Only items concerning mental status were dependent on the survey mode and sequence of administration. Items on physical status were not affected. Normative data for standardized telephone questionnaires could contribute to a better comparability with the results of the corresponding standardized paper questionnaires.

Fracture-related hip pain in elderly patients with proximal femoral fracture after discharge from stationary treatment

Background: Proximal femoral fracture is a common condition in the elderly but very little is known about fracture‐related hip pain in these patients after discharge from stationary treatment.

Prognostic value of a low post-exercise ankle brachial index as assessed by primary care physicians

OBJECTIVE We aimed to investigate whether the post-exercise ankle brachial index (ABI) performed by primary care physicians offers useful information for the prediction of death or cardiovascular events, beyond the traditional resting ABI. An additional focus was on patients with intermittent claudication and normal resting ABI. METHODS Using data from the 5-year follow-up of 6468 elderly patients in the primary care setting in Germany (getABI study) we used multivariate Cox regression models adjusted for age, gender and conventional risk factors to determine the association of resting ABI and/or post-exercise ABI and all-cause mortality/morbidity. RESULTS Mean post-exercise ABI in the total cohort was 0.977 and resting ABI was 1.034. For post-exercise ABI, a threshold value of 0.825 had nearly the same sensitivity (28.6%) and specificity (85.7%) as the conventionally used resting ABI with a cut-off value of 0.9 to predict death. Compared to patients with normal post-exercise ABI, a low post-exercise ABI was associated with an almost identical risk increase for mortality (hazard ratio [HR] 1.56, 95% confidence interval [CI] 1.30-1.86) as a low resting ABI (HR 1.65; CI 1.39-1.97) and/or myocardial infarction/stroke. Slight differences were observed for coronary/carotid revascularisation and peripheral revascularisation/amputation. In combined models it could not be shown that post-exercise ABI yielded relevant additional information for the prognosis of mortality and/or myocardial infarction/stroke, not even in the subgroup analysis of patients with intermittent claudication and normal resting ABI. CONCLUSIONS It could not be shown that the post-exercise ABI is a useful tool for the prognosis of mortality and/or myocardial infarction/stroke beyond the resting ABI.

Diagnosis and treatment of osteoporosis in postmenopausal women with distal radius fracture in Germany

ABSTRACT Objective: The aim of this study was to evaluate osteoporosis diagnosis and treatment on the basis of medical history, at hospital discharge, and 6–12 months after discharge, as well as to assess the frequency of subsequent fractures in postmenopausal women with distal radius fracture. Research design and methods: A prospective, observational study of hospitalized women aged 55 years and older with an isolated distal radius fracture from minimal trauma. Subjects were recruited in 242 acute care hospitals in Germany. Outcome measures: Potential risk factors for osteoporosis, frequency of osteoporosis assessment, frequency of medication treatment and subsequent fractures 6–12 months after discharge. Results: Among 2031 patients we identified 652 appropriate postmenopausal women. Less than one-third of patient histories contained any bone density parameters, and only a minority of subjects (33%, 217) underwent bone density assessment while in hospital. Of these, 55% (119) were diagnosed with low bone density, yet only 30% of those were prescribed supplements (calcium/vitamin D) and/or specific osteoporosis medication (mostly bisphosphonates) at discharge. Six to twelve months after hospital discharge, the low rate of treatment had not changed substantially. In the interval, 4.3% had sustained a subsequent fracture from minimal trauma: 1.4% a distal radius fracture (0.3% a refracture) and 2.9% a hip joint or other fracture (not specified). A significant age difference between those with and without subsequent distal radius fractures was found ( p = 0.01) but not a significant difference between patients with or without osteoporosis medication ( p = 0.79), primarily because the case numbers were too small. Conclusions: A substantial proportion of postmenopausal women hospitalized with distal radius fracture were not sufficiently evaluated or treated for their potential risk of osteoporosis.

Relationship between lipid parameters and the presence of peripheral arterial disease in elderly patients.

SUMMARY Conclusion: These findings are in contrast to previous studies. While lipid levels alone cannot be used for supporting the PAD diagnosis or the risk factor for these patients, this should not preclude PAD patients from receiving adequate lipid lowering treatment.
