A white raven detected by imaging.

The purpose of this case report is to describe a rare case of a patient with a phaeochromocytoma with several cardiovascular complications, which can be attributed to the tumour. Detection of a phaeochromocytoma sometimes needs a 'Sherlock Holmes spirit' or simply time.

Cost-effectiveness of involving nurse specialists for adult patients with urinary incontinence in primary care compared to care-as-usual: an economic evaluation alongside a pragmatic randomized controlled trial.

AIMS: To determine the 12-month, societal cost-effectiveness of involving urinary incontinence (UI) nurse specialists in primary care compared to care-as-usual by general practitioners (GPs). METHODS: From 2005 until 2008 an economic evaluation was performed alongside a pragmatic multicenter randomized controlled trial comparing UI patients receiving care by nurse specialists with patients receiving care-as-usual by GPs in the Netherlands. One hundred eighty-six adult patients with stress, urgency, or mixed UI were randomly allocated to the intervention and 198 to care-as-usual; they were followed for 1 year. Main outcome measures were Quality Adjusted Life Year (QALY(societal) ) based on societal preferences for health outcomes (EuroQol-5D), QALY(patient) based on patient preferences for health outcomes (EuroQol VAS), and Incontinence Severity weighted Life Year (ISLY) based on patient-reported severity and impact of UI (ICIQ-UI SF). Health care resource use, patient and family costs, and productivity costs were assessed. Data were collected by three monthly questionnaires. Incremental cost-effectiveness ratios were calculated. Uncertainty was assessed using bootstrap simulation, and the expected value of perfect information was calculated (EVPI). RESULTS: Compared to care-as-usual, nurse specialist involvement costs € 16,742/QALY(societal) gained. Both QALY(patient) and ISLY yield slightly more favorable cost-effectiveness results. At a threshold of € 40,000/QALY(societal,) the probability that the intervention is cost-effective is 58%. The EVPI amounts to € 78 million. CONCLUSIONS: Based on these results, we recommend adopting the nurse specialist intervention in primary care, while conducting more research through careful monitoring of the effectiveness and costs of the intervention in routine practice.

Feasibility and acceptability of a computerised system with automated reminders for prescribing behaviour in primary care.

OBJECTIVE: To evaluate the feasibility and acceptability of a computer reminder system (CRS) to improve prescribing behaviour in general practice and to explore the strengths and weaknesses of a reminder system. One group of GPs received reminders on cholesterol lowering drugs, the other group on antibiotics, asthma and COPD drugs. METHODS: Process evaluation of the computer reminder system being used by 53 GPs in 20 practices, by means of an analysis of the research database of the CRS. In addition, a questionnaire and semi-structured face-to-face interview were conducted with all GP practices, two project leaders, and one technical consultant. RESULTS: The strategy was largely carried out as planned, although the development period for the CRS had to be extended. Nine percent of the GPs dropped out. We found a significant learning curve without extinguishing effect (p=0.03) for the antibiotics reminders. The questionnaire showed that, in general, GPs were satisfied with the user-friendliness and the content of the different types of reminders, but less satisfied with certain specific technical performance issues of the system. The GPs reported mixed feelings towards the CRS in the interviews. They were generally positive about the guidelines themselves, but negative regarding to the organisational context and the method of implementing the CRS. GPs stated that they sometimes manipulated the system to bypass reminders. Interviews with the project leaders and technical consultant revealed barriers to cooperation and miscommunication between the different parties, and technical problems with multiple updates of the GP information system and the operating system. CONCLUSIONS: This process evaluation demonstrated that the implementation of the CRS was mainly carried out as planned, but the subjective experience of working with the CRS was not only positive. Participating GPs had mixed feelings, and quite a number of barriers need to be addressed to facilitate large-scale implementation of the CRS. Costs cannot be neglected, so it is important to analyse the balance between costs and effects.

Open access echocardiography is feasible in the Netherlands.

OBJECTIVES: In an urban region in the Netherlands, general practitioners (GPs) were offered an open access echocardiographic service. We report the outcomes of the first two years of this project. METHODS: GPs were given a course on the indications and restrictions for diagnostic referral as well as the interpretation of echocardiographic results. Indications were restricted to `dyspnoea', `cardiac murmur' and `peripheral oedema'. A uniform request form was developed, using ticking boxes for quick completion. The echocardiogram was performed within one week after the request. Results were interpreted by the cardiologist according to the criteria of the Dutch, European and American Societies of Echocardiography. RESULTS: Sixty GPs from 43 general practices participated, covering a practice population of 130,000 persons. During a period of 24 months, 198 patients were referred. Only 1.5% of the workload of the echocardiography department was due to requests from GPs. The GPs kept well to the agreements on indications for echocardiography (91% approved reasons). An abnormal echocardiographic outcome was found in 53% of all patients. For `cardiac murmur' this was 52%, for `dyspnoea' 63%, and for `peripheral oedema' 58%. Left ventricular dysfunction was present in 49 patients (25%); diastolic dysfunction was present in most of them (39 patients, 19%). Systolic dysfunction (LVEF < 40%) was found in 19 patients (10%). Twenty patients (10%) appeared to have relevant aortic or mitral valve disease. CONCLUSION: GPs did not overuse the open access echocardiographic service; they possibly used it conservatively. To prevent underdiagnosis of left ventricular dysfunction, diagnostic strategies in which electrocardiogram, NT-pro-BNP and echocardiography are combined, should be developed.

Interventions to improve outpatient referrals from primary care to secondary care.

BACKGROUND: The primary care specialist interface is a key organisational feature of many health care systems. Patients are referred to specialist care when investigation or therapeutic options are exhausted in primary care and more specialised care is needed. Referral has considerable implications for patients, the health care system and health care costs. There is considerable evidence that the referral processes can be improved. OBJECTIVES: To estimate the effectiveness and efficiency of interventions to change outpatient referral rates or improve outpatient referral appropriateness. SEARCH STRATEGY: We conducted electronic searches of the Cochrane Effective Practice and Organisation of Care (EPOC) group specialised register (developed through extensive searches of MEDLINE, EMBASE, Healthstar and the Cochrane Library) (February 2002) and the National Research Register. SELECTION CRITERIA: Randomised controlled trials, controlled clinical trials, controlled before and after studies and interrupted time series of interventions to change or improve outpatient referrals. Participants were primary care physicians. The outcomes were objectively measured provider performance or health outcomes. DATA COLLECTION AND ANALYSIS: Two reviewers independently extracted data and assessed study quality. MAIN RESULTS: Seventeen studies involving 23 separate comparisons were included. Nine studies (14 comparisons) evaluated professional educational interventions. Ineffective strategies included: passive dissemination of local referral guidelines (two studies), feedback of referral rates (one study) and discussion with an independent medical adviser (one study). Generally effective strategies included dissemination of guidelines with structured referral sheets (four out of five studies) and involvement of consultants in educational activities (two out of three studies). Three studies evaluated organisational interventions (patient management by family physicians compared to general internists, attachment of a physiotherapist to general practices and requiring a second 'in-house' opinion prior to referral), all of which were effective. Five studies (six comparisons) evaluated financial interventions. Two studies evaluating change from a capitation based to mixed capitation and fee-for-service system and from a fee-for-service to a capitation based system (with an element of risk sharing for secondary care services) observed a reduction in referral rates. Modest reductions in referral rates of uncertain significance were observed following the introduction of the general practice fundholding scheme in the United Kingdom (UK). One study evaluating the effect of providing access to private specialists demonstrated an increase in the proportion of patients referred to specialist services but no overall effect on referral rates. AUTHORS' CONCLUSIONS: There are a limited number of rigorous evaluations to base policy on. Active local educational interventions involving secondary care specialists and structured referral sheets are the only interventions shown to impact on referral rates based on current evidence. The effects of 'in-house' second opinion and other intermediate primary care based alternatives to outpatient referral appear promising.

The reliability of diagnosis using store-and-forward teledermatology.

We compared diagnoses made by a teledermatologist from digital photographs and patient histories sent from general practitioners using a store-and-forward technique and those made by another dermatologist in a face-to-face consultation with the same patients. A total of 117 patients (mean age 47 years) were referred by 18 general practitioners for diagnosis of a skin condition. Between one and seven digital images were transmitted per case. In 31% of the cases, three images were transmitted. There was full concordance between store-and-forward and face-to-face diagnoses in 57 of 106 cases (54%); in 10 cases (9%) there was overlap between the differential diagnoses provided by the teledermatologist and the face-to-face consultant. Diagnostic categories with relatively high concordances were eczema and follicular eruptions. General practitioners need to be trained in the making of digital images and in giving a good patient history.

[The value of joint general practitioner and rheumatologist consultations in primary care patients]. / De waarde van een gezamenlijk consult van huisartsen en reumatologen bij patiënten in de eerste lijn.

OBJECTIVE: To compare the effects of regular referral by general practitioners to the Rheumatology outpatients' clinic with that of joint consultations by general practitioners (GPs) and rheumatologists, and to compare the subsequent treatment policy followed. DESIGN: Randomised. METHOD: In 1999 and 2000 all rheumatological patients who, according to the 17 participating GPs in the Maastricht region had an indication for referral, were referred to the outpatients' clinic or seen during a joint consultation where three GPs and one rheumatologist decided on a treatment policy in the presence of the patient. Agreement about diagnosis and diagnostic and therapeutic approaches between the rheumatologists and GPs was determined using questionnaires. The patient's state of health was assessed using the 'EuroQol health-related quality of life questionnaire' (EuroQol) and their satisfaction was determined by means of questionnaires. RESULTS: One hundred and sixty-six patients were included: 45 (27%) men and 121 (73%) women, with an average age of 53.7 years (SD: 14). The rheumatologists and the GPs differed in opinion on the diagnosis in 64% of the patients. Agreement on diagnosis resulted in greater agreement on the treatment policy than when there were discrepancies about the diagnosis. The rheumatologist used additional diagnostic tools and follow-up consultations at the outpatient clinic (78% and 65%) more frequently than during the joint consultation (44% and 15%). Patient satisfaction and general state of health were comparable in both groups.

Are premature ventricular contractions always harmless?

INTRODUCTION: Premature ventricular contractions (PVCs) are among the most prevalent arrhythmias. PVCs lead to haemodynamically insufficient heartbeats. Their presence is considered rather insignificant, but this widespread assumption is not supported by research evidence. CASES: We present three cases of patients commonly seen in daily general practice, with a range of presentations, varying from incidental (harmless) PVCs to frequent and potentially symptomatic PVCs. DISCUSSION: In more frequent PVCs (> 10% heart beats) fatigue and exertional dyspnoea may occur. When > 20% of heart beats are PVCs, patients may develop cardiomyopathy and heart failure. Incidental PVCs are harmless. Anti-arrhythmic drug treatment should be considered in case of frequent PVCs but also catheter ablation appears an effective treatment option. CONCLUSION: Altogether, PVCs may not be harmless, depending on their occurrence rate. Research data from primary care settings on epidemiology and natural course is needed.

Age is an independent risk factor for left atrial dysfunction: results from an observational study.

Introduction. The degenerative changes of myocardial tissue are thought to influence left atrial (LA) function. Changes of left atrial function are generally due to changes in left ventricle (LV) compliance. But valvular dysfunction and hypertension as comorbidity cannot be ignored. Women have a different clinical profile compared with men concerning the risk of heart failure. We investigated the influence of increasing age and gender corrected for comorbidity, on left atrial function.Methods. Using an open access echocardiography database, supplemented with additional LA function measurements, we defined three different LA function parameters. Odds ratios (OR) were calculated to reproduce the relation between age, gender and LA function. The association between age, gender and LA function was estimated, and corrected for comorbid conditions as valve disease, high blood pressure and LV dysfunction, using logistic regression.Results. Higher age was positively correlated with increased LA volume, decreased ejection fraction and increased LA kinetic energy. Age per decade increase, corrected for comorbidity, resulted in an increased risk of LA dysfunction (OR between 1.5 and 1.9). Gender had little influence on LA function parameters except for LA maximal volume. Men had a significantly larger LA maximal volume compared with women. Conclusions. In this open access echocardiography database, increasing age was correlated with LA dysfunction. Age per decade increase, corrected for comorbid conditions such as mitral and aortic valve disease, hypertension and heart failure, is an independent risk factor for LA dysfunction. The gender influence on LA dysfunction seems to be limited. (Neth Heart J 2010;18:243-7.).

The effect of computer reminders on GPs' prescribing behaviour: a cluster-randomised trial.

OBJECTIVE: It is difficult to control drug-prescribing behaviour in general practice, despite the development and distribution of guidelines. The purpose of this study was to assess the effect on drug-prescribing behaviour of implementing prescribing guidelines by means of a reactive computer reminder system (CRS). DESIGN: Cluster-randomised controlled trial with an incomplete block design in the south of the Netherlands: 25 GPs (7 GP practices) received reminders about antibiotics and asthma/COPD prescriptions, 28 GPs (7 GP practices) received reminders about cholesterol prescriptions. Prescription guidelines were integrated into the computerised GP information system. MEASUREMENTS: Both performance indicators and prescription volumes were calculated as the main outcome measures. Next to individual volume measure, sum scores were constructed on the volume measures per drug group (antibiotics, asthma/COPD and cholesterol). RESULTS: Variation between GPs turned out to be larger and more skewed than expected. No differences between groups were found for indicators and volumes related to recommendations advocating certain drugs. Although there was a tendency towards clinically relevant results for prescription volumes that were supposed to drop, the difference in sum score between the groups was not significant. For antibiotic prescriptions that were supposed to drop, the sum score for the intervention group was 28.2 (95% CI: 20.8-44.5) prescriptions per 1000 patients per GP, while this was 39.7 (95% CI: 29.7-64.1) for the control group (p 0.2). For prescriptions asthma/COPD that were supposed to drop, the sum score for the intervention group was 1.1 (95% CI: 0.6-2.6) prescriptions per 1000 patients per GP, while this was 2.2 (95% CI: 1.4-4.3) for the control group (p 0.1). On three specific recommendations (on quinolones for cystitis, corticosteroids for CPOD, and antibiotics for acute sore throat) significant differences were found. CONCLUSIONS: This study turned out to be underpowered due to high inter doctor variation in prescribing behaviour. Nevertheless, computerised reminders sometimes have a favourable effect on restricting certain drugs that are not or no longer indicated in general practice.

Joint consultation of general practitioner and rheumatologist: does it matter?

OBJECTIVE: To assess the effects of joint consultation on referral behaviour of general practitioners (GPs) in a prospective cohort study. METHODS: All patients with rheumatological complaints that 17 participating GPs, from the area of the University Hospital Maastricht, wanted to refer during a two year inclusion period (n=166) were eligible for inclusion. These patients were either referred to the outpatient clinic, or presented at a joint consultation held every six weeks at the practice of the GP, where groups of three GPs presented their patients to a visiting, consulting rheumatologist. The number of patients referred by each GP a year at the end of the trial, comparing participating and non-participating GPs, was the main outcome measure. RESULTS: During two years of inclusion, the 17 participating GPs presented 166 patients. The number of patients referred by each GP a year decreased for the participating GPs by 62% at the end of the whole study. By contrast, non-participating GPs maintained the same rate of referral. The range of diagnoses remained proportionally the same throughout the study, with the exception of fibromyalgia. The referral rate of this diagnosis decreased significantly (p=0.001). CONCLUSIONS: Joint consultation seems to be a good strategy in influencing the referral behaviour of GPs in the area of rheumatology. The decrease in referral is substantial and can subsequently lead to a reduction of waiting lists.

Use of out of hours services: a comparison between two organisations.

OBJECTIVES: To investigate differences in numbers and characteristics of patients using primary or emergency care because of differences in organisation of out of hours care. BACKGROUND: Increasing numbers of self referrals at the accident and emergency (A&E) department cause overcrowding, while a substantial number of these patients exhibit minor injuries that can be treated by a general practitioner (GP). METHODS: Two different organisations of out of hours care in two Dutch cities (Heerlen and Maastricht) were investigated. Important differences between the two organisations are the accessibility and the location of primary care facility (GP cooperative). The Heerlen GP cooperative is situated in the centre of the city and is respectively 5 km and 9 km away from the two A&E departments situated in the area of Heerlen. This GP cooperative can only be visited by appointment. The Maastricht GP cooperative has free access and is located within the local A&E department. During a three week period all registration forms of patient contacts with out of hours care (GP cooperative and A&E department) were collected and with respect to the primary care patients a random sample of one third was analysed. RESULTS: For the Heerlen and Maastricht GP cooperative the annual contact rate, as extrapolated from our data, per 1000 inhabitants per year is 238 and 279 respectively (chi(2)((1df))=4.385, p=0.036). The contact rate at the A&E departments of Heerlen (n=66) and Maastricht (n=52) is not different (chi(2)((1df))=1.765, p=0.184). Some 51.7% of the patients attending the A&E department in Heerlen during out of hours were self referred, compared with 15.9% in Maastricht (chi(2)((1df))=203.13, p<0.001). CONCLUSIONS: The organisation of out of hours care in Maastricht has optimised the GP's gatekeeper function and thereby led to fewer self referrals at the A&E department, compared with Heerlen.

Patients at the outpatient rheumatology clinic: do they really need to be there?

BACKGROUND: The workload at many outpatient clinics within the Dutch health care system has been growing relentlessly, resulting in unacceptable waiting lists and reduced accessibility. Assessing streams of patients and introducing a method of accelerated referral of patients back to the general practitioner (GP) under specialist guidance could help to alleviate these problems. METHODS: Seventeen GPs collaborated with rheumatologists during a 2-year period in a 'joint consultation' model in which GPs and rheumatologists discussed patients together. All patient charts belonging to patients who had been referred to the outpatient clinic by these 17 GPs were identified. Rheumatologists assessed whether or not these patients could be referred back to the participating GPs under the guidance of the specialist in the joint consultation model. RESULTS: Of 276 eligible patients, 121 were discharged from the outpatient clinic. Eighty-seven patients required specialist follow-up, 22 patients refused to participate, and six patients were not entered into the study by the rheumatologist. Some 21 patients eventually entered the study, 18 of whom were referred back to the GP. CONCLUSION: The role of joint consultation appears to be limited. Improving the referral behavior of GPs should take precedence over transferring follow-up from the outpatient clinic to the primary care level.
