RESUMEN
BACKGROUND: Children 0-4 years attending childcare are more prone to acquire infections than home-cared children. Childcare illness absenteeism due to fever is mostly driven by fear towards fever in childcare staff and parents. This may cause high childcare absenteeism, healthcare service use, and work absenteeism in parents. This study evaluates a multicomponent intervention targeting determinants of decision-making among childcare staff on illness absenteeism due to fever and common infections. METHODS: The multicomponent intervention was developed based on the Intervention Mapping approach and consisted of (i) an educational session, (ii) a decision tool, (iii) an information booklet and (iv) an online video. The intervention was evaluated in a cluster randomized controlled trial in Southern Netherlands. Nine centres received the intervention and nine provided childcare-as-usual. Primary outcome measure was the percentage of illness absenteeism on cluster level, defined as number of childcare days absent due to illness on total of registered childcare contract days in a 12-week period. Secondary outcome measures included intended behaviour, attitude, risk perception, knowledge and self-efficacy of childcare staff. Outcomes were analyzed using linear mixed models accounting for clustering. Knowledge was descriptively analysed. RESULTS: Overall illness absenteeism was comparable in intervention (2.95%) and control group (2.52%). Secondary outcomes showed significant improvements in intervention group regarding intended behaviour, two of three attitude dimensions. Knowledge increased compared with control but no differences regarding self-efficacy. CONCLUSION: The intervention was not effective in reducing illness absenteeism. However, the intervention improved determinants of decision-making such as intended behaviour, attitude, and knowledge on fever. TRIAL REGISTRATION: NTR6402 (registered on 21 April 2017).

BACKGROUND: The role of general practitioners (GPs) in skin cancer care is increasing. Previous, hospital-based studies suggest that GPs might not have the capabilities to gain responsibility concerning skin cancer care. OBJECTIVES: To evaluate the current approach of GPs towards skin lesions suspected of malignancy in the Netherlands. METHODS: In three general practices, all consultations in 2015 concerning skin lesions suspected of malignancy were identified and reviewed. Patients demographics, circumstances of consultation, evaluation of skin lesion(s), presumed diagnosis, diagnostic accuracy and policy were evaluated. RESULTS: Five hundred and eighty consultations were identified. Patient took initiative for encounter in 90%. Case-finding occurred in 2%. Diagnostic tools were used in 22%; dermoscopy was used in 8% and a diagnostic excision in 10%. The GP diagnosed a benign lesion in 69%. Therapeutic interventions were applied in 31% and a wait-and-see policy in 40%. The diagnosis after referral was a benign tumour in 39% of the cases, a malignancy in 29% and a premalignant lesion in 17%. The positive predictive value (PPV) of the presumed benign, malignant and premalignant diagnoses was 86%, 54% and 18%, respectively. CONCLUSIONS: Most lesions that are presented to the GP with a suspicion of a malignancy appear to be benign lesions. In the examined practices, the diagnosis of the GP is mainly based on clinical examination and little use is made of available diagnostic tools. The use of a diagnostic tool like a biopsy might prevent unnecessary referrals.

BACKGROUND: Evidence has shown that children 0-4 year-old attending childcare are prone to acquire infections compared to children cared for at home, with fever being the most common symptom. Illness absenteeism due to fever and common infections is substantial and mostly driven by unrealistic concerns and negative attitude towards fever of both childcare staff and parents, resulting in illness absenteeism from childcare, work absenteeism among parents and healthcare service use. The objective of this study is to optimise decision making among childcare staff on illness absenteeism due to fever and common infections in childcare. Underlying determinants of behavioural change were targeted by means of a multicomponent intervention. METHODS: A multicomponent intervention was developed to improve decision making, using the stepwise approach of Intervention Mapping, and in close collaboration with stakeholders and experts. The intervention consisted of 1) a two-hour educational session on fever among childcare staff; 2) an online video for childcare staff and parents emphasising key information of the educational session; 3) a decision tool for childcare staff and parents in the format of a traffic light system to estimate the severity of illness and corresponding advices for childcare staff and parents; 4) an information booklet regarding childhood fever, common infections, and self-management strategies for childcare staff and parents. The multicomponent intervention will be evaluated in a cluster randomised trial with a 12-week follow-up period and absenteeism due to illness (defined as the percentage of childcare days absent due to illness on the total of childcare days during a 12-week period) as primary outcome measure. Secondary outcome measures are: incidence rate and duration of illness episodes, knowledge, attitude, self-efficacy, and risk perception on fever and common infections of childcare staff and parents, healthcare service use in general and paracetamol use, and work absenteeism of parents. DISCUSSION: This study aims to develop a multicomponent intervention and to evaluate to what extent illness absenteeism due to fever and common infections can be affected by implementing a multicomponent intervention addressing decision making and underlying determinants among childcare staff and parents of children attending daycare.

UNLABELLED: Currently, there are many diagnostic self-tests on body materials available to consumers. The aim of this study was to assess the effect of an online decision aid on diagnostic self-testing for cholesterol and diabetes on knowledge among consumers with an intention to take these tests. A randomized controlled trial was designed. A total of 1259 consumers with an intention to use a diagnostic cholesterol or diabetes self-test were selected from an existing Dutch Internet panel. The intervention group was invited to view an online decision aid offering general information on self-testing and test-specific information on cholesterol and diabetes self-testing, including indications for testing, how to perform the test and interpreting the result. The placebo condition consisted of a limited information sheet. Multiple regression analysis showed that the knowledge level in the diabetes arm was higher in the intervention group than in the control group (B = 0.657; 95% CI, 0.011-1.303), as was the number of participants with an informed choice (OR, 1.672; 95% CI, 1.134-2.465). No differences were found in the cholesterol arm. Consumers who are considering doing a self-test should have access to independent information on self-testing and be encouraged to read this information. TRIAL REGISTRATION: Dutch Trial Register: NTR 3149.

Diagnostic reasoning is considered to be based on the interaction between analytical and non-analytical cognitive processes. Gut feelings, a specific form of non-analytical reasoning, play a substantial role in diagnostic reasoning by general practitioners (GPs) and may activate analytical reasoning. In GP traineeships in the Netherlands, trainees mostly see patients alone but regularly consult with their supervisors to discuss patients and problems, receive feedback, and improve their competencies. In the present study, we examined the discussions of supervisors and their trainees about diagnostic reasoning in these so-called tutorial dialogues and how gut feelings feature in these discussions. 17 tutorial dialogues focussing on diagnostic reasoning were video-recorded and transcribed and the protocols were analysed using a detailed bottom-up and iterative content analysis and coding procedure. The dialogues were segmented into quotes. Each quote received a content code and a participant code. The number of words per code was used as a unit of analysis to quantitatively compare the contributions to the dialogues made by supervisors and trainees, and the attention given to different topics. The dialogues were usually analytical reflections on a trainee's diagnostic reasoning. A hypothetico-deductive strategy was often used, by listing differential diagnoses and discussing what information guided the reasoning process and might confirm or exclude provisional hypotheses. Gut feelings were discussed in seven dialogues. They were used as a tool in diagnostic reasoning, inducing analytical reflection, sometimes on the entire diagnostic reasoning process. The emphasis in these tutorial dialogues was on analytical components of diagnostic reasoning. Discussing gut feelings in tutorial dialogues seems to be a good educational method to familiarize trainees with non-analytical reasoning. Supervisors need specialised knowledge about these aspects of diagnostic reasoning and how to deal with them in medical education.

BACKGROUND: Family physicians' diagnostic gut feelings have proved to be valuable. But what about patients' gut feelings? Research has shown that patients' gut feelings may contribute to their physicians' clinical reasoning. Dutch medical tribunals consider patients' worry useful for doctors' diagnostic process. However, how general practitioners and other primary care professionals recognize gut feelings of patients and deal with them in their decision making is yet unclear. We aim to explore how primary care professionals perceive patients' gut feelings and use this information in their decision-making. METHODS: We interviewed 30 Dutch and Belgian primary care professionals, exploring how they recognize and value patients' gut feelings. We coded all interviews using a descriptive content analysis in an iterative process. Data sufficiency was achieved. RESULTS: Primary care professionals acknowledged gut feelings in their patients, and most participants found them a useful source of information. Patients' gut feelings might alert them to possible hidden problems and might provide quicker insight into patients' perceptions. Primary care professionals listed a whole series of wordings relating to trusting or distrusting the situation or to any changes in normal patterns. A patient's gut feeling was often a reason for the professionals to explore patients' worries and to reconsider their own clinical reasoning. CONCLUSIONS: Primary care professionals regularly considered patients' gut feelings useful, as they might contribute to their clinical reasoning and to a deeper understanding of the patient's problem. The next step could be to ask patients themselves about their gut feelings and explore their diagnostic value.

OBJECTIVES: The risk of subsequent fractures is double the risk of having a first fracture. We analysed whether this risk is constant or not over time. METHODS: A population-based study in 4140 postmenopausal women, aged between 50 and 90 years, on radiographic confirmed clinical fractures from menopause onwards analysed by Cox regression. RESULTS: A total of 924 (22%) women had a first fracture and 243 (26% of 924) a subsequent fracture. Of all first fractures, 4% occurred in each year from menopause onwards, while after a first fracture 23% of all subsequent fractures occurred within 1 year and 54% within 5 years. When calculated from time of first fracture, the relative risk (RR) of subsequent fracture was 2.1 (95% CI 1.7 to 2.6) and remained increased over 15 years. When calculated for specific time intervals after a first fracture, the RR was 5.3 (95% CI 4.0 to 6.6) within 1 year, 2.8 (95% CI 2.0 to 3.6) within 2-5 years, 1.4 (95% CI 1.0 to 1.8) within 6-10 years and 0.41 (95% CI 0.29 to 0.53) after >10 years. CONCLUSIONS: From menopause onwards, clinical fractures cluster in time, indicating the need for early action to prevent subsequent fractures.

OBJECTIVE: Newly presented unexplained complaints (UCs) are common in general practice. Factors influencing the transition of newly presented into persistent UCs have been scarcely investigated. We studied the number and the nature of diagnoses made over time, as well as factors associated with UCs becoming persistent. Finally, we longitudinally studied factors associated with quality of life (QoL). METHODS: Prospective cohort study in general practice of patients presenting with a new UC. Data sources were case record forms, patient questionnaires and electronic medical registries at inclusion, 1, 6 and 12 months. Presence of complaints and diagnoses made over time were documented. Potential risk factors were assessed in mixed-effect logistic and linear regression models. RESULTS: Sixty-three GPs included 444 patients (73% women; median age 42) with unexplained fatigue (70%), abdominal complaints (14%) and musculoskeletal complaints (16%). At 12 months, 43% of the patients suffered from their initial complaints. Fifty-seven percent of the UCs remained unexplained. UCs had (non-life-threatening) somatic origins in 18% of the patients. QoL was often poor at presentation and tended to remain poor. Being a male [odds ratio (OR) 0.6; 95% confidence interval (CI) 0.4-0.8] and GPs' being more certain about the absence of serious disease (OR 0.9; 95% CI 0.8-0.9) were the strongest predictors of a diminished probability that the complaints would still be present and unexplained after 12 months. The strongest determinants of complaint persistence [regardless of (un)explicability] were duration of complaints >4 weeks before presentation (OR 2.6; 95% CI 1.6-4.3), musculoskeletal complaint at baseline (OR 2.3; 1.2-4.5), while the passage of time acted positively (OR 0.8 per month; 95% CI 0.78-0.84). Musculoskeletal complaints, compared to fatigue, decreased QoL on the physical domain (4.6 points; 2.6-6.7), while presence of psychosocial factors decreased mental QoL (5.0; 3.1-6.9). CONCLUSION: One year after initial presentation, a large proportion of newly presented UCs remained unexplained and unresolved. We identified determinants that GPs might want to consider in the early detection of patients at risk of UC persistence and/or low QoL.

BACKGROUND: Since the 1990s, individualisation, participation, normalisation and inclusion have been the main principles of care for people with intellectual disability (ID). Autonomy has become an important issue for these people. This review of the literature tried to answer the question: how do people with ID exercise autonomy in relation to health? METHOD: Searches in Cochrane, Medline and PsycINFO were based on the following aspects of autonomy: self-determination, independence, self-regulation and self-realisation. RESULTS: Thirty-nine of 791 articles met our criteria, including 14 on self-determination, seven on independence, 15 on self-regulation and three on self-realisation. CONCLUSIONS: In spite of decades of promoting autonomy, the exercise of autonomy in relation to health has so far rarely been an issue in the literature.

What role does uncertainty play in the doctor's diagnostic reasoning process? Would it not be better to avoid uncertainty as much as possible? In this article we answer this question from an epistemological perspective. Doctors build up relevant, situational knowledge during the diagnostic process through listening, observation and interpretation during their contact with the patient. Uncertainty can play a crucial role in this. We use a practical case to illustrate how allowing in some uncertainty - in the form of gut feelings - can improve the quality of the diagnostic thought process.

STUDY DESIGN: A systematic overview of the literature and an agreement study. OBJECTIVES: The aim of this study is to explore the inter-professional agreement of diagnostic musculoskeletal ultrasound (DMUS) between physical therapists (PT) and radiologists, using a new classification strategy based upon the therapeutic consequences in patients with shoulder pain. BACKGROUND: DMUS is frequently used by PTs, although the agreement regarding traditional diagnostic labels between PTs and radiologists is only fair. Nevertheless, DMUS could be useful when used as a stratifying-tool. METHODS: First, a systematic overview of current evidence was performed to assess which traditional diagnostic labels could be recoded into new treatment related categories (referral to secondary care, corticosteroid injections, physical therapy, watchful waiting). Next, kappa values were calculated for these categories between PTs and radiologists. RESULTS: Only three categories were extracted, as none of the traditional diagnostic labels were classified into the 'corticosteroid injection' category. Overall, we found moderate agreement to stratify patients into treatment related categories and substantial agreement for the category 'referral to secondary care'. Both categories 'watchful waiting' and 'indication for physical therapy' showed moderate agreement between the two professions. CONCLUSION: Our results indicate that the agreement between radiologists and PTs is moderate to substantial when labelling is based on treatment consequences. DMUS might be able to help the PT to guide treatment, especially for the category 'referral to secondary care' as this showed the highest agreement. However, as this is just an explorative study, more research is needed, to validate and assess the consequences of this stratification classification for clinical care.

The effectiveness of influenza vaccination in the elderly has long been a topic of debate, fueled by the absence of direct evidence on its effect on mortality. It is argued that new placebo-controlled trials should be undertaken to resolve this uncertainty. However, such trials may be ethically questionable. We provide an overview of the ethical challenges of an influenza vaccine efficacy trial designed to evaluate mortality in the elderly. An important condition in the justification of a trial is the existence of genuine uncertainty regarding the answer to a research question. Therefore an extensive analysis of the existing levels of knowledge is needed to support the conclusion that an effect of vaccination on mortality is uncertain. Even if a so-called 'clinical equipoise' status applies, denying a control group vaccination would be problematic because vaccination is considered 'competent care' and withholding vaccination could substantially increase patients' risk for influenza and its complications. Given the high burden of disease and proven benefits of vaccination, the importance of a trial is unlikely to outweigh the risk patients are exposed to. While a placebo-controlled trial in vaccine refusers may be considered, such a trial is unlikely to meet methodological standards regarding trial size and generalizability. We conclude that a new trial is unlikely to provide a direct answer, let alone change current policy. At the same time, given the lack of consensus on this topic, we invite researchers considering vaccine efficacy trials on mortality to address the ethical challenges as discussed.

OBJECTIVE: Incorrect and unnecessary antibiotic prescribing enhancing bacterial resistance rates might be reduced if viral and bacterial lower respiratory tract infections (LRTI) could be differentiated clinically. Whether this is possible is often doubted but has rarely been studied in general practice. STUDY DESIGN AND SETTING: This was an observational cohort study in 15 general practice surgeries in the Netherlands. RESULTS: Etiologic diagnoses were obtained in 112 of 234 patients with complete data (48%). Viral pathogens were found as often as bacterial pathogens. Haemophilus (para-) influenzae was most frequently found. None of the symptoms and signs correlated statistically significantly with viral or bacterial LRTI. Erythrocyte sedimentation rate >50 (odds ratio [OR] 2.3-3.3) and C-reactive protein (CRP) >20 (OR 2.1-4.6) were independent predictors for viral LRTI and bacterial LRTI when compared with microbiologically unexplained LRTI. CONCLUSION: Extensive history-taking and physical examination did not provide items that predict viral or bacterial LRTI in adult patients in daily general practice. We could not confirm CRP to differentiate between viral and bacterial LRTI.

BACKGROUND: The mental health burden on primary care is substantial and increasing. Anxiety is a major contributor. Stepped collaborative care (SCC) is implemented worldwide to improve patient outcomes, but long term real-world evaluations of SCC do not exist. Using routinely used electronic medical records from more than a decade, we investigated changes in anxiety prevalences, whether physicians made distinction between non-severe and severe anxiety, and whether these groups were referred and treated differently, both non-pharmacologically and pharmacologically. METHODS: Retrospective assessment of anxiety care parameters recorded by 54 general practitioners between 2003 and 2014, in the electronic medical records of a dynamic population of 49,841-69,413 primary care patients. RESULTS: Substantial shifts in anxiety care parameters have occurred. The prevalence of anxiety symptoms doubled to 0.9% and of anxiety disorders almost tripled to 1.1%. Use of ICPC codes seemed comprehensive and use of instruments to support in anxiety level differentiation increased to 13% of anxiety symptom and 7% of anxiety disorder patients in 2014. Minimal interventions were used more frequently, especially for anxiety symptoms (OR 21 [95% CI 5.1-85]). The antidepressant prescription rates decreased significantly for anxiety symptoms (OR 0.5 [95% CI 0.4-0.8]) and anxiety disorders (OR 0.6 [95% CI 0.4-0.8]). More patients were referred to psychologists and psychiatrists. CONCLUSIONS: We found shifts in anxiety care parameters that follow the principles of SCC. Future primary care research should comprehensively assess the use of the SCC range of therapeutic options, tailored to patients with all different anxiety severity levels.

OBJECTIVE: To determine the relationship between osteoporosis and the presence of specific and nonspecific medical conditions in postmenopausal women. To what extent is this relationship useful in detecting osteoporosis in daily general practice. STUDY DESIGN AND SETTING: Subjects were 1,684 postmenopausal women registered with 23 general practitioners. Multivariate logistic regression analysis was done with 52 disease variables and 24 biometrical and lifestyle variables, using BMD as the dependent variable. Bivariate analysis was performed to calculate their contribution to the risk of having osteoporosis. RESULTS: Having more than one disease was associated with a lower prevalence of osteoporosis. A positive association with the presence of osteoporosis was only found for the use of corticosteroids, gastric surgery, and cervical complaints. The risk for osteoporosis in the high risk category increased from 39 to 71% in women using oral corticosteroids, from 39 to 56% in women with a history of gastric surgery, and from 39 to 63% in women with cervical complaints. CONCLUSION: The clinical relevance of medical conditions for detecting osteoporosis is limited. However, all patients using oral corticosteroids and patients with a history of gastric surgery should be checked for the presence of osteoporosis. Cervical compaints in the high risk category was associated with osteoporosis.

OBJECTIVE: To construct a quick algorithm to detect patients with low bone mineral density (BMD) and osteoporosis and determine its applicability in daily general practice. DESIGN: Cross-sectional study in all 9107 postmenopausal women, aged 50-80, registered at 12 general practice centers. SUBJECTS AND MEASUREMENTS: All healthy women (5303) and 25% of the remaining group (943/3804) were invited to participate. Of 6246 invited women, 4725 (76%) participated. The women were questioned (state of health, medical history, family history, and food questionnaire) and examined [weight, height, body mass index (BMI), and BMD of the lumbar spine]. STATISTICS: Multivariable, stepwise backward and forward logistic regression analyses were performed, with BMD of the lumbar spine (L2-L4, cut-off points at 0.800 g/cm(2) for osteoporosis and 0.970 g/cm(2) for low BMD) as the dependent variable. An algorithm was constructed with those variables that correlated statistically significantly and clinically relevant with the presence of both osteoporosis and low BMD. RESULTS: The prevalence of osteoporosis was 23%, that of low BMD was 65%. Only three variables (age, BMI, and fractures) were statistically significant and clinically relevant correlated with the presence of both osteoporosis and low BMD. Age (OR 2.70 for osteoporosis and OR 1.77 for low BMD) and fractures during the past five years (OR 3.60 for osteoporosis and OR 2.85 for low BMD) were found to be the key predictors. From the algorithm the absolute risks varied from 9% to 51% for osteoporosis and from 48% to 84% for low BMD. The corresponding relative risks varied from 1.0 to 5.7 and from 1.0 to 1.8. CONCLUSIONS: Using an algorithm with age, BMI, and fracture history subgroups at high risk could be identified. However, in whatever combination, many women with osteoporosis could not be identified. Despite the differences in methods, we found predictors for osteoporosis which were comparable with the results of other cross-sectional studies, meaning that the first selection of patients at high risk for low BMD can be done adequately by both specialists and general practitioners.

Elevated total cholesterol and plasma fibrinogen levels and smoking are risk factors for cardiovascular disease, whose inter-relationships are influenced by both gender and age. The aim of this study was to investigate the effect of smoking on fibrinogen levels in a hypercholesterolemic population subdivided on the basis of gender and age. The study included 492 hypercholesterolemic subjects, divided into four subpopulations: men and women, aged 26-49 and 50-66 years. Mean fibrinogen levels among smokers and non-smokers in the four subpopulations of this hypercholesterolemic cohort followed mean total cholesterol levels. Three subpopulations (men <50 years, men >/=50 years and women >/=50 years) showed differences in mean total cholesterol and fibrinogen values between smokers and non-smokers (total cholesterol 7.23+/-0.54 vs. 7.40+/-0.93 mmol/l and fibrinogen 2.79+/-0.48 vs. 3.23+/-0.72 g/l in men <50 years; total cholesterol 7.17+/-0.43 vs. 7.50+/-0.60 mmol/l and fibrinogen 3.11+/-0.44 vs. 3.68+/-0.66 g/l in men >/=50 years and 7.41+/-0.59 vs. 7.65+/-0.73 mmol/l and fibrinogen 3.29+/-0.61 vs. 3.58+/-0.71 g/l in women >/=50 years). These values correspond to a percentage difference between smokers and nonsmokers in total cholesterol and fibrinogen of 2.4% and 15.8% in men <50 years, 4.6% and 18.3% in men >/=50 years and 3.2% and 8.8% in women >/=50 years. All differences were significant ( P<0.05), except for total cholesterol in the younger men (<50 years). No differences between smokers and non-smokers were observed in the younger female group (<50 years). Except in the younger female group (<50 years), significant differences between smokers and non-smokers were also observed in the number of subjects exceeding the upper reference value of fibrinogen (>4.0 g/l), the highest percentage being found for the older women smokers (>/=50 years) (29%). In Conclusion, smoking elevates fibrinogen levels in hypercholesterolemic men (<50 years; >/=50 years) and older women (>/=50 years), but not in younger women (<50 years).

Elevated total cholesterol, the related low-density lipoprotein-cholesterol, high-density lipoprotein-cholesterol, triglycerides, and smoking habits are risk factors for cardiovascular disease. The objective of this study was to investigate the influence of habitual smoking on these parameters in 492 hypercholesterolemic men and women, aged between 26 and 66 years. Relative differences between smokers and non-smokers in the mean values of total cholesterol, low-density and hig-density lipoprotein-cholesterol, and triglycerides were 2.2%, 5.5%, -8.1%, and 13.7%, respectively. These differences were statistically significant (P<0.04). Over the entire cohort, including men and women, age did not affect the mean values significantly, except for total cholesterol and triglyceride values in smoking women, which were significantly higher in women over 50 years than in the younger women (P=0.011 and P=0.004). In both men and women, regardless of smoking habits, 43%-59% of subjects exceeded the upper reference range value for low-density lipoprotein-cholesterol (4.9 mmol/l), while 38%-59% exceeded the upper reference range value for triglycerides (2.0 mmol/l) and 82%-91% had values below the lower reference range value for high-density lipoprotein-cholesterol (0.9 mmol/l for men, 1.2 mmol/l for women). Smoking habits hardly influenced the extent to which reference values were exceeded, except for low-density lipoprotein-cholesterol in all subjects (higher percentage for smokers, P=0.041). Similar results were obtained for age, except for triglycerides in smoking women, wich showed high values in 26% of women <50 years versus 50% of women > or = 50 years (P=0.026).

Despite its frequent use, little is known about the ability of the erythrocyte sedimentation rate to discriminate between 'pathology' (inflammatory diseases and malignancies) and 'no pathology' in general practice. This has been studied by following 362 patients who presented to their general practitioner with a new complaint, for which the general practitioner considered determination of the erythrocyte sedimentation rate to be indicated. The test was performed at the local hospital laboratory and the patients were seen again after three months, in order to establish the follow-up diagnoses. By comparing the test results with the follow-up diagnoses, combined with receiver operating characteristic curves and regression analysis, the erythrocyte sedimentation rate was found to have a reasonable discriminating ability with respect to malignancies and inflammatory diseases (sensitivity 53%, specificity 94%, positive predictive value 48%, negative predictive value 91%, odds ratio 15.1). The upper limit for the normal erythrocyte sedimentation rate should be set at approximately 12 mm hour-1 for men and 28 mm hour-1 for women, and needs no correction for age. It is concluded that the erythrocyte sedimentation rate still deserves a place in the general practitioner's daily routine.
