Cardiovascular risk screening of patients with serious mental illness or use of antipsychotics in family practice.

BACKGROUND: Patients with serious mental illness (SMI) and patients on antipsychotics (AP) have an elevated risk for cardiovascular diseases. In the Netherlands, the mental healthcare for these patients is increasingly taken care of by family practitioners (FP) as a result of a shift from secondary to primary care. Therefore, it is essential to increase our knowledge regarding the characteristics of this patient group and the (somatic) care provided by their FPs. The aim was to examine the rate of cardiovascular risk screening in patients with SMI or the use of AP in family practice. METHODS: We performed a retrospective cohort study of 151.238 patients listed in 24 family practices in the Netherlands. From electronic medical records we extracted data concerning diagnoses, measurement values of CVR factors, medication and frequency of visits over a 2 year period. Primary outcome was the rate of patients who were screened for CVR factors. We compared three groups: patients with SMI/AP without diabetes or CVD (SMI/AP-only), patients with SMI/AP and diabetes mellitus (SMI/AP + DM), patients with SMI/AP and a history of cardiovascular disease (SMI/AP + CVD). We explored factors associated with adequate screening using multilevel logistic regression. RESULTS: We identified 1705 patients with SMI/AP, 834 with a SMI diagnosis, 1150 using AP. The screening rate for CVR in the SMI/AP-only group (n = 1383) was adequate in 8.5%. Screening was higher in the SMI/AP - +DM (n = 206, 68.4% adequate, OR 24.6 (95%CI, 17.3-35.1) and SMI/AP + CVD (n = 116, 26.7% adequate, OR 4.2 (95%CI, 2.7-6.6). A high frequency of visits, age, the use of AP and a diagnosis of COPD were associated with a higher screening rate. In addition we also examined differences between patients with SMI and patients using AP without SMI. CONCLUSION: CVR screening in patients with SMI/AP is performed poorly in Dutch family practices. Acceptable screening rates were found only among SMI/AP patients with diabetes mellitus as comorbidity. The finding of a large group of AP users without a SMI diagnosis may indicate that FPs often prescribe AP off-label, lack information about the diagnosis, or use the wrong code.

Is the plasma aldosterone-to-renin ratio associated with blood pressure response to treatment in general practice?

BACKGROUND: Individualized antihypertensive treatment based on specific biomarkers such as renin may lead to more effective blood pressure control in patients with newly diagnosed essential hypertension. Recent studies suggested that the plasma aldosterone-to-renin ratio (ARR) may also be a candidate predictor for this purpose. OBJECTIVE: To assess whether the ARR is associated with the blood pressure response to antihypertensive treatment in patients with newly diagnosed hypertension. METHODS: In this prospective cohort study in primary care, we determined the ARR in patients with newly diagnosed hypertension prior to starting treatment. Treatment was categorized in five groups: no medication, use of angiotensin-converting-enzyme inhibitor or angiotensin receptor blocker, use of calcium channel blocker, use of diuretic, or use of beta blocker. We examined the relation between the ARR and blood pressure response within 1 year of treatment, taking into account the type of antihypertensive treatment and adjusting for gender, age, baseline blood pressure, and comorbidity. RESULTS: Out of 304 patients, we used 947 measurements (727 no medication, 220 medication) for analysis. There was no association between the ARR and the response in blood pressure, and this applied to each treatment group. Target blood pressure, defined as systolic blood pressure <140 mmHg, was reached in 31% of patients. There was no association between the ARR and reaching target blood pressure (OR 1.002, 95% CI 0.983-1.022). CONCLUSION: The ARR is not associated with the response in blood pressure within 1 year of antihypertensive treatment in primary care.

General practitioners' perspectives on management of early-stage chronic kidney disease: a focus group study.

BACKGROUND: Guideline adherence in chronic kidney disease management is low, despite guideline implementation initiatives. Knowing general practitioners' (GPs') perspectives of management of early-stage chronic kidney disease (CKD) and the applicability of the national interdisciplinary guideline could support strategies to improve quality of care. METHOD: Qualitative focus group study with 27 GPs in the Netherlands. Three analysts open-coded and comparatively analysed the data. Mind-mapping sessions were performed after data-saturation. RESULTS: Five themes emerged: defining CKD, knowledge and awareness, patient-physician interaction, organisation of CKD care and value of the guideline. A key finding was the abstractness of the CKD concept. The GPs expressed various perspectives about defining CKD and interpreting estimated glomerular filtration rates. Views about clinical relevance influenced the decision-making, although factual knowledge seems lacking. Striving to inform well enough without creating anxiety and to explain suitably for the intellectual ability of the patient caused tension in the patient-physician interaction. Integration with cardiovascular disease-management programmes was mentioned as a way of implementing CKD care in the future. The guideline was perceived as a rough guide rather than a leading document. CONCLUSION: CKD is perceived as an abstract rather than a clinical concept. Abstractness plays a role in all formulated themes. Management of CKD patients in primary care is complex and is influenced by physician-bound considerations related to individual knowledge and perception of the importance of CKD. Strategies are needed to improve GPs' understanding of the concept of CKD by education, a holistic approach to guidelines, and integration of CKD care into cardiovascular programmes. TRIAL REGISTRATION: Not applicable.

Web-based consultation between general practitioners and nephrologists: a cluster randomized controlled trial.

Background: Consultation of a nephrologist is important in aligning care for patients with chronic kidney disease (CKD) at the primary-secondary care interface. However, current consultation methods come with practical difficulties that can lead to postponed consultation or patient referral instead. Objective: This study aimed to investigate whether a web-based consultation platform, telenephrology, led to a lower referral rate of indicated patients. Furthermore, we assessed consultation rate, quality of care, costs and general practitioner (GPs') experiences with telenephrology. Methods: Cluster randomized controlled trial with 47 general practices in the Netherlands was randomized to access to telenephrology or to enhanced usual care. A total of 3004 CKD patients aged 18 years or older who were under primary care were included (intervention group n = 1277, control group n = 1727) and 2693 completed the trial. All practices participated in a CKD management course and were given an overview of their CKD patients. Results: The referral rates amounted to 2.3% (n = 29) in the intervention group and 3.0% (n = 52) in the control group, which was a non-significant difference, OR 0.61; 95% CI 0.31 to 1.23. The intervention group's consultation rate was 6.3% (n = 81) against 5.0% (n = 87) (OR 2.00; 95% CI 0.75-5.33). We found no difference in quality of care or costs. The majority of GPs had a positive opinion about telenephrology. Conclusion: The data in our study do not allow for conclusions on the effect of telenephrology on the rate of patient referrals and provider-to-provider consultations, compared to conventional methods. It was positively evaluated by GPs and was non-inferior in terms of quality of care and costs.

Adherence to chronic kidney disease guidelines in primary care patients is associated with comorbidity.

Background: GPs insufficiently follow guidelines regarding consultation and referral for chronic kidney disease (CKD). Objective: To identify patient characteristics and quality of care (QoC) in CKD patients with whom consultation and referral recommendations were not followed. Method: A 14 month prospective observational cohort study of primary care patients with CKD stage 3-5. 47 practices participated, serving 207469 people. 2547 CKD patients fulfilled consultation criteria, 225 fulfilled referral criteria. We compared characteristics of patients managed by GPs with patients receiving nephrologist co-management. We assessed QoC as adherence to monitoring criteria, CKD recognition and achievement of blood pressure (BP) targets. Results: Patients treated in primary care despite a consultation recommendation (94%) had higher eGFR values (OR 1.07; 95% CI: 1.05-1.09), were less often monitored for renal function (OR 0.42; 95% CI: 0.24-0.74) and potassium (OR 0.56; 95% CI: 0.35-0.92) and CKD was less frequently recognised (OR 0.46; 95% CI: 0.31-0.68) than in patients with nephrologist co-management. Patients treated in primary care despite referral recommendation (70%) were older (OR 1.03; 95% CI:1.01-1.06) and had less cardiovascular disease (OR 0.37; 95% CI: 0.19-0.73). Overall, in patients solely managed by GPs, CKD recognition was 50%, monitoring disease progression in 36% and metabolic parameters in 3%, BP targets were achieved in 51%. Monitoring of renal function and BP was positively associated with diabetes (OR 3.10; 95% CI: 2.47-3.88 and OR 7.78; 95% CI: 3.21-18.87) and hypertension (OR 3.19; 95% CI: 2.67-3.82 and OR 3.35; 95% CI: 1.45-7.77). Conclusion: Patients remaining in primary care despite nephrologists' co-management recommendations were inadequately monitored, and BP targets were insufficiently met. CKD patients without cardiovascular comorbidity or diabetes require extra attention to guarantee adequate monitoring of renal function and BP.

Quality of chronic kidney disease management in primary care: a retrospective study.

BACKGROUND: Early detection and appropriate management of chronic kidney disease (CKD) in primary care are essential to reduce morbidity and mortality. AIM: To assess the quality of care (QoC) of CKD in primary healthcare in relation to patient and practice characteristics in order to tailor improvement strategies. DESIGN AND SETTING: Retrospective study using data between 2008 and 2011 from 47 general practices (207 469 patients of whom 162 562 were adults). METHOD: CKD management of patients under the care of their general practitioner (GP) was qualified using indicators derived from the Dutch interdisciplinary CKD guideline for primary care and nephrology and included (1) monitoring of renal function, albuminuria, blood pressure, and glucose, (2) monitoring of metabolic parameters, and alongside the guideline: (3) recognition of CKD. The outcome indicator was (4) achieving blood pressure targets. Multilevel logistic regression analysis was applied to identify associated patient and practice characteristics. RESULTS: Kidney function or albuminuria data were available for 59 728 adult patients; 9288 patients had CKD, of whom 8794 were under GP care. Monitoring of disease progression was complete in 42% of CKD patients, monitoring of metabolic parameters in 2%, and blood pressure target was reached in 43.1%. GPs documented CKD in 31.4% of CKD patients. High QoC was strongly associated with diabetes, and to a lesser extent with hypertension and male sex. CONCLUSION: Room for improvement was found in all aspects of CKD management. As QoC was higher in patients who received structured diabetes care, future CKD care may profit from more structured primary care management, e.g. according to the chronic care model. KEY POINTS: Quality of care for chronic kidney disease patients in primary care can be improved. In comparison with guideline advice, adequate monitoring of disease progression was observed in 42%, of metabolic parameters in 2%, correct recognition of impaired renal function in 31%, and reaching blood pressure targets in 43% of chronic kidney disease patients. Quality of care was higher in patients with diabetes. Chronic kidney disease management may be improved by developing strategies similar to diabetes care.

Liraglutide reverses pronounced insulin-associated weight gain, improves glycaemic control and decreases insulin dose in patients with type 2 diabetes: a 26 week, randomised clinical trial (ELEGANT).

AIMS/HYPOTHESIS: The best treatment strategy for a patient with type 2 diabetes who shows pronounced weight gain after the introduction of insulin treatment is unclear. We determined whether addition of a glucagon-like peptide-1 (GLP-1) analogue could reverse pronounced insulin-associated weight gain while maintaining glycaemic control, and compared this with the most practised strategy, continuation and intensification of standard insulin therapy. METHODS: In a 26-week, randomised controlled trial (ELEGANT), conducted in the outpatient departments of one academic and one large non-academic teaching hospital in the Netherlands, adult patients with type 2 diabetes with ≥ 4% weight gain during short-term (≤ 16 months) insulin therapy received either open-label addition of liraglutide 1.8 mg/day (n = 26) or continued standard therapy (n = 24). A computer-generated random number list was used to allocate treatments. Participants were evaluated every 4-6 weeks for weight, glycaemic control and adverse events. The primary endpoint was between-group weight difference after 26 weeks of treatment (intention to treat). RESULTS: Of 50 randomised patients (mean age 58 years, BMI 33 kg/m(2), HbA1c 7.4% [57 mmol/mol]), 47 (94%) completed the study; all patients were analysed. Body weight decreased by 4.5 kg with liraglutide and increased by 0.9 kg with standard therapy (mean difference -5.2 kg [95% CI -6.7, -3.6 kg]; p < 0.001). The respective changes in HbA1c were -0.77% (-8.4 mmol/mol) and +0.01% (+0.1 mmol/mol) (difference -0.74% [-8.1 mmol/mol]) ([95% CI -1.08%, -0.41%] [-11.8, -4.5 mmol/mol]; p < 0.001); respective changes in insulin dose were -29 U/day and +5 U/day (difference -33 U/day [95% CI -41, -25 U/day]; p < 0.001). In five patients (19%), insulin could be completely discontinued. Liraglutide was well tolerated; no severe adverse events or severe hypoglycaemia occurred. CONCLUSIONS/INTERPRETATION: In patients with pronounced insulin-associated weight gain, addition of liraglutide to their treatment regimen reverses weight, decreases insulin dose and improves glycaemic control, and hence seems a valuable therapeutic option compared with continuation of standard insulin treatment.

Organizational determinants of high-quality routine diabetes care.

OBJECTIVE: Randomized trials showed that changes in healthcare organization improved diabetes care. This study aimed to identify which organizational determinants were associated with patient outcomes in routine diabetes care. DESIGN: Observational study, in which multilevel regression analyses were applied to examine the impact of 12 organizational determinants on diabetes care as separate measures and as a composite score. SETTING: Primary care practices in the Netherlands. SUBJECTS: 11,751 patients with diabetes in 354 practices. MAIN OUTCOME MEASURES: Patients' recorded glycated hemoglobin (HbA1c), systolic blood pressure, and serum cholesterol levels. RESULTS: A higher score on the composite measure of organizational determinants was associated with better control of systolic blood pressure (p = 0.017). No effects on HbA1C or cholesterol levels were found. Exploration of specific organizational factors found significant impact of use of an electronic patient registry on HbA1c (OR = 1.80, 95% CI 1.12-2.88), availability of patient leaflets on systolic blood pressure control (OR = 2.59, 95% CI 1.06-6.35), and number of hours' nurse education on cholesterol control (OR = 2.51, 95% CI 1.02-6.15). CONCLUSION: In routine primary care, it was found that favorable healthcare organization was associated with a number of intermediate outcomes in diabetes care. This finding lends support to the findings of trials on organizational changes in diabetes care. Notably, the composite measure of organizational determinants had most impact.

Initial implementation of a web-based consultation process for patients with chronic kidney disease.

PURPOSE: A Web-based consultation system (telenephrology) enables family physicians to consult a nephrologist about a patient with chronic kidney disease. Relevant data are exported from the patient's electronic file to a protected digital environment from which advice can be formulated by the nephrologist. The primary purpose of this study was to assess the potential of telenephrology to reduce in-person referrals. METHODS: In an observational, prospective study, we analyzed telenephrology consultations by 28 family practices and 5 nephrology departments in the Netherlands between May 2009 and August 2011. The primary outcome was the potential reduction of in-person referrals, measured as the difference between the number of intended referrals as stated by the family physician and the number of referrals requested by the nephrologist. The secondary outcome was the usability of the system, expressed as time invested, the implementation in daily work hours, and the response time. Furthermore, we evaluated the questions asked. RESULTS: One hundred twenty-two new consultations were included in the study. In the absence of telenephrology, 43 patients (35.3%) would have been referred by their family physicians, whereas the nephrologist considered referral necessary in only 17 patients (13.9%) (P <.001). The family physician would have treated 79 patients in primary care. The nephrologist deemed referral necessary for 10 of these patients. Time investment per consultation amounted to less than 10 minutes. Consultations were mainly performed during office hours. Response time was 1.6 days (95% CI, 1.2-1.9 days). Most questions concerned estimated glomerular filtration rate, proteinuria, and blood pressure. CONCLUSION: A Web-based consultation system might reduce the number of referrals and is usable. Telenephrology may contribute to an effective use of health facilities by allowing patients to be treated in primary care with remote support by a nephrologist.

Vascular outcomes in patients with screen-detected or clinically diagnosed type 2 diabetes: Diabscreen study follow-up.

PURPOSE: Screening guidelines for type 2 diabetes recommend targeting high-risk individuals. Our objective was to assess whether diagnosis of type 2 diabetes based on opportunistic targeted screening results in lower vascular event rates compared with diagnosis on the basis of clinical signs or symptoms. METHODS: In a prospective, nonrandomized, observational study, we enrolled patients aged 45 to 75 years from 10 family practices in the Netherlands with a new diagnosis of type 2 diabetes, detected either by (1) opportunistic targeted screening (n = 359) or (2) clinical signs or symptoms (n = 206). Patients in both groups received the same guideline-concordant diabetes care. The main group outcome measure was a composite of death from cardiovascular disease (CVD), nonfatal myocardial infarction, and nonfatal stroke. RESULTS: Baseline vascular disease was more prevalent in the opportunistic targeted screening group, mainly ischemic heart disease (12.3% vs 3.9%, P = .001) and nephropathy (16.9% vs 7.1%, P = .002). After a mean follow-up of 7.7 years (SD = 2.4 years) and 7.1 years (SD = 2.7 years) for the opportunistic targeted screening and clinical diagnosis groups, respectively, composite primary event rates did not differ significantly between the 2 groups (9.5% vs 10.2%, P = .78; adjusted hazard ratio 0.67, 95% confidence interval, 0.36-1.25; P = .21). There were also no significant differences in the separate event rates of deaths from CVD, nonfatal myocardial infarction, and nonfatal strokes. CONCLUSIONS: Opportunistic targeted screening for type 2 diabetes detected patients with higher CVD morbidity at baseline when compared with clinical diagnosis but showed similar CVD mortality and major CVD morbidity after 7.7 years. Opportunistic targeted screening and guided care appears to improve vascular outcomes in type 2 diabetes in primary care.

Patients' and partners' illness perceptions in screen-detected versus clinically diagnosed type 2 diabetes: partners matter!

BACKGROUND: In type 2 diabetes, educational interventions that target differences between patients' and partners' illness perceptions have been advocated. OBJECTIVE: To investigate how the route to diagnosis of type 2 diabetes (through screening versus clinical symptoms) affects illness perceptions of patients and their partners. METHODS: In a cross-sectional study, we enrolled patients aged 40-75 years from general practices in the Netherlands with a new diagnosis of type 2 diabetes (≤3 years), detected by either screening (n = 77) or clinical symptoms (n = 32). Patients and their partners each completed a postal Brief Illness Perception Questionnaire (Brief IPQ), and up-to-date clinical data were obtained from their GP. The Brief IPQ scores of the screening and clinical diagnosis groups were compared for both patients and partners, and multiple variable linear regression models with Brief IPQ scores as outcomes were developed. RESULTS: The route to diagnosis did not appear to have a strong influence on patients' illness perceptions but did influence illness perceptions of their partners. Partners of patients diagnosed through screening perceived greater consequences for their own life, had a stronger feeling that their patient-partners had control over their diabetes, were more concerned about their partners' diabetes, and believed that their patient-partners experienced more diabetes symptoms, compared with partners of patients who were diagnosed through clinical symptoms. CONCLUSIONS: The route to diagnosis of type 2 diabetes has a greater impact on the illness perceptions of partners than that of patients. Professionals in diabetes education and treatment should consider these differences in their approach to patient care.

Stepwise treatment of uncontrolled HyperTensioN (Stepwise-HTN): Study design of a cluster randomised controlled trial in primary care.

BACKGROUND: Uncontrolled hypertension is a major health problem, and a key risk factor for cardiovascular disease. Most patients are detected and managed in primary care, but approximately 50% remains uncontrolled. Our aim is to assess whether a guided stepwise work-up management strategy for patients with uncontrolled hypertension in primary care would result in better blood pressure control in these patients compared to usual care. METHODS: A cluster randomised controlled trial aiming at randomizing 40 general practices to either "a protocolised stepwise work-up" or to "usual care". Uncontrolled hypertension is defined as an office blood pressure (BP) >140/90 mmHg while being prescribed three or more antihypertensive drugs simultaneously from different therapeutic classes for three or more months in an adequate dose. In the intervention arm, patients with uncontrolled hypertension will receive the stepwise approach, consisting of (i) excluding a white coat effect, (ii) re-evaluation of lifestyle, (iii) re-evaluation of drug adherence, (iv) optimalisation of antihypertensive treatment and (v) referral if the office BP is still >140/90 mmHg. The control group receives usual care in a regular program for cardiovascular risk management. The primary outcome is the absolute difference in the mean 24-h systolic BP between intervention and control arm after 8 months. Secondary outcomes include differences in the percentage of patients achieving a controlled BP, and time to reach a controlled BP. CONCLUSION: If stepwise treatment of uncontrolled hypertension is proven effective, the strategy could be implemented by blending the approach to the cardiovascular risk management already applied in general practice.

Structuring and validating a cost-effectiveness model of primary asthma prevention amongst children.

BACKGROUND: Given the rising number of asthma cases and the increasing costs of health care, prevention may be the best cure. Decisions regarding the implementation of prevention programmes in general and choosing between unifaceted and multifaceted strategies in particular are urgently needed. Existing trials on the primary prevention of asthma are, however, insufficient on their own to inform the decision of stakeholders regarding the cost-effectiveness of such prevention strategies. Decision analytic modelling synthesises available data for the cost-effectiveness evaluation of strategies in an explicit manner. Published reports on model development should provide the detail and transparency required to increase the acceptability of cost-effectiveness modelling. But, detail on the explicit steps and the involvement of experts in structuring a model is often unevenly reported. In this paper, we describe a procedure to structure and validate a model for the primary prevention of asthma in children. METHODS: An expert panel was convened for round-table discussions to frame the cost-effectiveness research question and to select and structure a model. The model's structural validity, which indicates how well a model reflects the reality, was determined through descriptive and parallel validation. Descriptive validation was performed with the experts. Parallel validation qualitatively compared similarity between other published models with different decision problems. RESULTS: The multidisciplinary input of experts helped to develop a decision-tree structure which compares the current situation with screening and prevention. The prevention was further divided between multifaceted and unifaceted approaches to analyse the differences. The clinical outcome was diagnosis of asthma. No similar model was found in the literature discussing the same decision problem. Structural validity in terms of descriptive validity was achieved with the experts and was supported by parallel validation. CONCLUSIONS: A decision-tree model developed with experts in round-table discussions benefits from a systematic and transparent approach and the multidisciplinary contributions of the experts. Parallel validation provides a feasible alternative to validating novel models. The process of structuring and validating a model presented in this paper could be a useful guide to increase transparency, credibility, and acceptability of (future, novel) models when experts are involved.

Yield of opportunistic targeted screening for type 2 diabetes in primary care: the diabscreen study.

PURPOSE: In screening for type 2 diabetes, guidelines recommend targeting high-risk individuals. Our objectives were to assess the yield of opportunistic targeted screening for type 2 diabetes in primary care and to assess the diagnostic value of various risk factors. METHODS: In 11 family practices (total practice population = 49,229) in The Netherlands, we conducted a stepwise opportunistic screening program among patients aged 45 to 75 years by (1) identifying high-risk individuals (=1 diabetes risk factor) and low-risk individuals using the electronic medical record, (2) obtaining a capillary fasting plasma glucose measurement, repeated on a separate day if the value was greater than 110 mg/dL, and (3) obtaining a venous sample if both capillary fasting plasma glucose values were greater than 110 mg/dL and at least 1 sample was 126 mg/dL or greater. We calculated the yield (percentage of invited patients with undiagnosed diabetes), number needed to screen (NNS), and diagnostic value of the risk factors (odds ratio and area under the receiver operating characteristic curve). RESULTS: We invited for a first capillary measurement 3,724 high-risk patients seen during usual care and a random sample of 465 low-risk patients contacted by mail. The response rate was 90% and 86%, respectively. Ultimately, 101 high-risk patients (2.7%; 95% confidence interval [CI], 2.2%-3.3%; NNS = 37) and 2 low-risk patients (0.4%; 95% CI, 0.1%-1.6%; NNS = 233) had undiagnosed diabetes (P <.01). The prevalence of diabetes among patients 45 to 75 years old increased from 6.1% to 6.8% as a result. Among diagnostic models containing various risk factors, a model containing obesity alone was the best predictor of undiagnosed diabetes (odds ratio = 3.2; 95% CI, 2.0-5.2; area under the curve=0.63). CONCLUSIONS: The yield of opportunistic targeted screening was fair; obesity alone was the best predictor of undiagnosed diabetes. Opportunistic screening for type 2 diabetes in primary care could target middle-aged and older adults with obesity.

Heart failure in primary care: prevalence related to age and comorbidity.

BACKGROUND: Diagnosing heart failure (HF) in primary care can be challenging, especially in elderly patients with comorbidities. Insight in the prevalence, age, comorbidity and routine practice of diagnosing HF in general practice may improve the process of diagnosing HF. AIM: To examine the prevalence of HF in relation to ageing and comorbidities, and routine practice of diagnosing HF in general practice. METHODS: A retrospective cohort study was performed using data from electronic health records of 56 320 adult patients of 11 general practices. HF patients were compared with patients without HF using descriptive analyses and χ2 tests. The following comorbidities were considered: chronic obstructive pulmonary disorder (COPD), diabetes mellitus (DM), hypertension, anaemia and renal function disorder (RFD). Separate analyses were performed for men and women. FINDINGS: The point prevalence of HF was 1.2% (95% confidence interval 1.13-1.33) and increased with each age category from 0.04% (18-44 years) to 20.9% (⩾85 years). All studied comorbidities were significantly (P<0.001) more common in HF patients than in patients without HF: COPD (24.1% versus 3.1%), DM (34.7% versus 6.5%), hypertension (52.7% versus 16.0%), anaemia (10.9% versus 2.3%) and RFD (61.8% versus 7.5%). N-terminal pro-BNP (NT-proBNP) was recorded in 38.1% of HF patients. CONCLUSIONS: HF is highly associated with ageing and comorbidities. Diagnostic use of NT-proBNP in routine primary care seems underutilized. Instruction of GPs to determine NT-proBNP in patients suspected of HF is recommended, especially In elderly patients with comorbidities.

What Patients with Mild-to-Moderate Kidney Disease Know, Think, and Feel about Their Disease: An In-Depth Interview Study.

INTRODUCTION: It is unknown what patients in primary care with mild-to-moderate chronic kidney disease (CKD) know, think, and feel about their diagnoses and how they value the information provided. The aim of the study was to explore their knowledge, thoughts, and experiences concerning their CKD and the information given to them. METHOD: Qualitative interview study with patients with mild-to-moderate CKD who know their diagnoses and are treated mainly by family physicians. RESULTS: Four themes arose: CKD literacy, coping with anxiety, prerequisites for self-management, and reciprocity in information provision. The participants filled deficiencies in their CKD knowledge with misconceptions and half-truth about causes, symptoms, and treatment. The anxiety about CKD at the time of diagnosis versus the feeling of irrelevance later on was due to the absence of CKD symptoms and their physicians' minimization of the seriousness of CKD. Participants failed to connect lifestyle and cardiovascular disease with CKD. Not all participants were well informed about the consequences that CKD might have. CKD literacy and willingness to change were both necessary to accept lifestyle changes. Further, the participants felt that it would be helpful when information comes with empathy and is tailored to patients' personal needs. CONCLUSIONS: Patients have various perceptions about their CKD. Exploring these perceptions could help match their needs with better-tailored information. Doctors should be aware that they can deliver inaccurate signals about CKD severity, so that patients fail to realize the potential impact of CKD. This makes them less open to lifestyle changes and improving their self-management.

Foot ulceration and lower limb amputation in type 2 diabetic patients in dutch primary health care.

OBJECTIVE: To determine the incidence of foot ulceration and lower limb amputation in type 2 diabetic patients in primary health care. RESEARCH DESIGN AND METHODS: Data on type 2 diabetes were collected by the Nijmegen Monitoring Project between 1993 and 1998 as part of a study of chronic diseases. The records of all patients recorded as having diabetic foot problems and those who died, moved to a nursing home, or were under specialist care were included. The annual incidence of foot ulceration was defined as the number of type 2 diabetic patients per patient-year who developed a new foot ulcer. Incidence of lower limb amputation was similarly defined. Additional information was collected on treatment of foot ulcers. RESULTS: The study population of type 2 diabetic patients increased from 511 patient-years in 1993 to 665 in 1998. The annual incidence of foot ulceration varied between 1.2 and 3.0% (mean 2.1) per year; 25% of the patients had recurrent episodes. The annual incidence of lower limb amputation varied between 0.5 and 0.8% (mean 0.6). Ten of the 15 amputees died, and 12 of 52 (23%) patients with ulceration had a subsequent amputation or a previous history of amputation. In 35 of the 73 (48%) episodes of ulceration, only the family physician provided treatment. Patients with foot problems were older and had more cardiovascular disease, retinopathy, and absent peripheral pulses. CONCLUSIONS: The incidence of foot ulceration and lower limb amputation in type 2 diabetes is low; nevertheless, recurrence rates of ulceration and risk of amputation are high, with high mortality.

[Timely referral for predialysis; multiple players in the field]. / Tijdig verwijzen voor predialyse; veel spelers aan zet.

Timely referral is essential in patients with end-stage renal disease. Time is needed to inform the patient on the options of dialysis or kidney transplantation and for the placement of arteriovenous fistulae if haemodialysis is indicated; early referral is associated with lower morbidity and mortality. A prerequisite for timely referral is that patients with chronic kidney disease are recognised, which involves the following factors: chronic kidney disease should be mentioned in the patient's history; the patient should be informed of the diagnosis; and patients, general practitioners, pharmacists and specialists should have knowledge of the risk factors for acute-on-chronic kidney disease. Timely referral for predialysis requires optimal collaboration between the patient and many health care professionals.
