Randomized controlled trial on cardiovascular risk management by practice nurses supported by self-monitoring in primary care

BACKGROUND: Treatment goals for cardiovascular risk management are generally not achieved. Specialized practice nurses are increasingly facilitating the work of general practitioners and self-monitoring devices have been developed as counseling aid. The aim of this study was to compare standard treatment supported by self-monitoring with standard treatment without self-monitoring, both conducted by practice nurses, on cardiovascular risk and separate risk factors. METHODS: Men aged 50–75 years and women aged 55–75 years without a history of cardiovascular disease or diabetes, but with a SCORE 10-year risk of cardiovascular mortality ≥5% and at least one treatable risk factor (smoking, hypertension, lack of physical activity or overweight), were randomized into two groups. The control group received standard treatment according to guidelines, the intervention group additionally received pro-active counseling and self-monitoring (pedometer, weighing scale and/ or blood pressure device). After one year treatment effect on 179 participants was analyzed. RESULTS: SCORE risk assessment decreased 1.6% (95% CI 1.0–2.2) for the control group and 1.8% (1.2–2.4) for the intervention group, difference between groups was .2% (−.6–1.1). Most risk factors tended to improve in both groups. The number of visits was higher and visits took more time in the intervention group (4.9 (SD2.2) vs. 2.6 (SD1.5) visits p < .001 and 27 (P(25) –P(75):20–33) vs. 23 (P(25) –P(75):19–30) minutes/visit p = .048). CONCLUSIONS: In both groups cardiovascular risk decreased significantly after one year of treatment by practice nurses. No additional effect of basing the pro-active counseling on self-monitoring was found, despite the extra time investment. TRIAL REGISTRATION: trialregister.nl NTR218

Discontinuation of reimbursement of benzodiazepines in the Netherlands: does it make a difference?

BACKGROUND: In an attempt to control chronic benzodiazepine use and its costs in the Netherlands, health care insurance reimbursement of this medication was stopped on January 1(st) 2009. This study investigates whether benzodiazepine prescriptions issued by general practitioners changed during the first two years following implementation of this regulation. METHODS: Registry study based on data from all benzodiazepine users derived from the Registration Network Groningen. This general practice-based research network collects longitudinal data on the primary care administered to about 30,000 patients. Based on the number of quarterly accumulated prescription days, a comparison was made of benzodiazepine prescriptions issued between 2007/2008 and 2009/2010. Also investigated was which type of user (i.e. short-term or long-term) showed the most change. RESULTS: Information on benzodiazepine prescriptions among 5,200 patients from 16 consecutive trimesters between 2007 and 2010 was available for analysis. A significant reduction in prescription days was observed between 2007/2008 and 2009/2010. Overall, an estimated 1.73 (CI:-1.94 to -1.53; p<0.001) days were less prescribed per trimester after the termination of reimbursement. In particular, short-term users experienced a reduction in prescription days in 2009 and 2010. The number of long-term users decreased by 2.3%, while the number of individuals that did not use increased by 4.2%. CONCLUSIONS: A total reduction of almost 14 prescription days was observed over eight trimesters after implementation of the regulation to terminate the reimbursement of benzodiazepines. Short-term users were mainly responsible for this reduction in prescription days in 2009 and 2010. Although long-term users did not alter their benzodiazepine use in 2009 and 2010, the number of long-term users decreased slightly

Perceived Adverse Drug Events in Heart Failure Patients' Perception and Related Factors

Background: Patients with heart failure (HF) often perceive adverse drug events (ADEs), affecting quality of life. For weighing the benefits and burden of medication in HF care, knowledge on patients' perception of ADEs is needed. Our aim was to assess these ADE perceptions and to identify factors related to these perceptions. Methods: A cross-sectional study was performed including HF patients recruited from primary care and outpatient clinics. Patients were included in the analysis if they perceived an ADE in the past 4 weeks. This information was collected using an open-ended question and a symptom checklist. Data on ADE perception were obtained using a modified version of the Revised Illness Perception Questionnaire. Demographic, clinical, and ADE characteristics were collected by self-administered questionnaire and chart review. The relations between these factors and ADE perceptions were analyzed using regression analyses. Results: In total, 261 HF patients perceived an ADE and completed the questionnaire. Patients reported 814 ADEs, of which 26% of the patients reported dizziness and 24% reported dry mouth as being the most prevalent. Almost half of the patients (46%) perceived their ADE as something serious, with major consequences for their daily life (40%) and reported to be worried (36%) about the ADE. Patients perceived the ADE as a chronic problem (91%), and the majority believed more in the ability of the health care provider to control the ADE (61%) than in their own ability (46%). Demographic and clinical variables had a limited contribution to the explained variance of ADE perceptions after adjusting for ADE characteristics, such as perceived severity. Conclusion: Patients with HF perceive particular negative consequences and emotional distress of symptomatic ADE. Open communication between patients and providers with attention for patients ADE perceptions would be valuable during the decision process of ADE management and may result in a regimen aligned with patients' preferences and needs

Skin lesions suspected of malignancy:an increasing burden on general practice

BACKGROUND: Skin cancer is believed to impose a heavy burden on healthcare services, but the burden of skin lesions suspected of malignancy on primary healthcare has never been evaluated. Therefore the aim of this study was to determine the demand for care in general practice due to these suspected skin lesions (i.e. lesions that are suspected of malignancy by either the patient or the GP). METHODS: Registry study based on data (2001–2010) from the Registration Network Groningen. This is a general practice registration network in the northern part of the Netherlands with an average annual population of approximately 30,000 patients. All patient contacts are coded according to the International Classification of Primary Care (ICPC). Consultations for skin lesions suspected of malignancy were selected according to the assigned ICPC codes. Subsequently, the number of consultations per year and the annual percent change in number of contacts (using the JoinPoint regression program) were calculated and analysed. Additionally, the percentage of patients referred to secondary care or receiving minor surgery within one year after the first contact were calculated. RESULTS: From 2001 onwards we found an annual increase in demand for care due to skin lesions suspected of malignancy of 7.3% (p < 0.01) and in 2010 the benign:malignant ratio was 10:1. In total 13.0% of the patients were referred and after 2006, minor surgery was performed on 31.2% of the patients. Most surgeries and referrals took place within 30 days. CONCLUSIONS: Suspected skin lesions impose an increasing burden on primary healthcare and most likely on healthcare costs as well. General practitioners should therefore be trained in diagnosing skin lesions suspected of malignancy, as a high diagnostic accuracy can save lives in the case of melanoma, and may also prevent unnecessary, costly, excisions and referrals to secondary healthcare

Health beliefs and perceived need for mental health care of anxiety and depression - The patients' perspective explored

Patients' illness representations and beliefs about treatment for depression and anxiety, as well as their perceived needs, are important for treatment. A systematic review was conducted of 71 studies describing the beliefs or perceived needs of patients and non-patients. Patients give multi-dimensional explanations for depression and see both psychological and medication treatment as helpful. People who suffer from depression have more positive beliefs about biological etiology and medication treatment than healthy people, or those with less severe depressive symptoms. Anxiety patients view psychological interventions as their best treatment option. Between 49% and 84% of the patients with depression or anxiety perceive a need for treatment, mostly for counseling and medication. All patients prefer psychological treatment forms to medication. A majority of patients view antidepressants as addictive and many perceive stigma and see practical and economic barriers to care. The most vulnerable groups in terms of seeking and receiving mental health care for depression and anxiety seem to be minority groups, as well as younger and older patients. More research is required into the specific needs of anxiety and depression patients. Open communication between patient and provider could lead to valuable improvements in treatment. (aut. ref.

Are lower urinary tract symptoms in men associated with cardiovascular diseases in a primary care population:a registry study

BACKGROUND: Although lower urinary tract symptoms (LUTS) seem to be related to cardiovascular disease (CVD) in men, it is unclear whether this relationship is unbiased. In order to investigate this relationship, we used longitudinal data for establishing the possible predictive value of LUTS for the development of CVD in a primary care population. METHODS: We performed a registry study using data from the Registration Network Groningen (RNG). All data from men aged 50 years and older during the study period from 1 January 1998 up to 31 December 2008 were collected. Cox proportional hazard regression analysis was used to determine the association between the proportions of CVD (outcome) and LUTS in our population. RESULTS: Data from 6614 men were analysed. The prevalence of LUTS increased from 92/1000 personyears (py) in 1998 up to 183/1000 py in 2008. For cardiovascular diseases the prevalence increased from 176/1000 py in 1998 up to 340/1000 py in 2008. The incidence numbers were resp. 10.2/1000 py (1998) and 5.1/1000 py (2008) for LUTS, and 12.9/1000 py (1998) and 10.4/1000 py (2008) for CVD. Of all men, 23.2% reported CVD (41.1% in men with LUTS vs 19.5% in men without LUTS, p < 0.01). The hazard ratio of LUTS for cardiovascular events, compared to no LUTS, in the adjusted multivariate model, was 0.921(95% CI: 0.824 - 1.030; p = 0.150). CONCLUSION: Based on the results, LUTS is not a factor that must be taken into account for the early detection of CVD in primary care

Single-cell screening of photosynthetic growth and lactate production by cyanobacteria

Background Photosynthetic cyanobacteria are attractive for a range of biotechnological applications including biofuel production. However, due to slow growth, screening of mutant libraries using microtiter plates is not feasible. Results We present a method for high-throughput, single-cell analysis and sorting of genetically engineered l-lactate-producing strains of Synechocystis sp. PCC6803. A microfluidic device is used to encapsulate single cells in picoliter droplets, assay the droplets for l-lactate production, and sort strains with high productivity. We demonstrate the separation of low- and high-producing reference strains, as well as enrichment of a more productive l-lactate-synthesizing population after UV-induced mutagenesis. The droplet platform also revealed population heterogeneity in photosynthetic growth and lactate production, as well as the presence of metabolically stalled cells. Conclusions The workflow will facilitate metabolic engineering and directed evolution studies and will be useful in studies of cyanobacteria biochemistry and physiology

Radiating low back pain in general practice:Incidence, prevalence, diagnosis, and long-term clinical course of illness

Objective. The aim of this study was to calculate the incidence and prevalence of radiating low back pain, to explore the long-term clinical course of radiating low back pain including the influence of radiculopathy (in a subsample of the study population) and non-radiating low back pain thereon, and to describe general practitioners' (GPs') treatment strategies for radiating low back pain. Design. A historic prospective cohort study. Setting. Dutch general practice. Subjects. Patients over 18 years of age with a first episode of radiating low back pain, registered by the ICPC code L86. Main outcome measures. Incidence and prevalence, clinical course of illness, initial diagnoses established by the GPs, and treatment strategies. Results. Mean incidence was 9.4 and mean prevalence was 17.2 per 1000 person years. In total, 390 patients had 1193 contacts with their GPs; 50% had only one contact with their GP. Consultation rates were higher in patients with a history of non-radiating low back pain and in patients with a diagnosis of radiculopathy in the first five years. In this study's subsample of 103 patients, L86 episodes represented radiculopathy in 50% of cases. Medication was prescribed to 64% of patients, mostly NSAIDs. Some 53% of patients were referred, mainly to physiotherapists and neurologists; 9% of patients underwent surgery. Conclusion. Watchful waiting seems to be sufficient general practice care in most cases of radiating low back pain. Further research should be focused on clarifying the relationship between radicular radiating low back pain, non-radicular radiating low back pain, and non-radiating low back pain
