Children and young people's consultation rates for psychosocial problems between 2016 and 2021 in the Netherlands.

BACKGROUND: Worldwide, there are concerns about declining mental health of children and young people (CYP). OBJECTIVES: To examine trends in GP consultation rates for psychosocial problems and the impact of the COVID-19 pandemic. METHODS: We performed a population-based cohort study using electronic GP records of CYP (0-24 years) living in the Rotterdam metropolitan area between 2016 and 2021. We calculated monthly consultation rates for psychosocial problems, stratified by age group and sex. We used negative binomial models to model the pre-COVID-19 trend, and estimate expected rates post-COVID-19 onset. We modelled the effect of COVID-19 infection rate and school closure on consultation rates per sex and age group. RESULTS: The cohort increased from 64801 to 92093 CYP between January 2016 and December 2021. Median age was 12.5 years and 49.3% was female. Monthly consultation rates increased from 2,443 to 4,542 consultations per 100,000 patient months over the six years. This trend (RR 1.009, 95%CI 1.008-1.011) started well before the COVID-19 pandemic. Consultation rates of adolescent girls and young women increased most strongly. Between March and May 2020, there was a temporary reduction in consultation rates, whereupon these returned to expected levels. COVID-19 infection rate and school closures showed small but significant associations with consultation rates for psychosocial problems but this did not affect the overall trend. Although consultation rates for psychosocial problems increased, this increment was stable over the entire study period. CONCLUSION: The COVID-19 pandemic did not significantly increase consultation rates for psychosocial problems in CYP. The consultation rates increased, especially in adolescent girls and young women.

CYP' consultation rates for psychosocial problems within general practice almost doubled between 2016 and 2021 in the Rotterdam metropolitan area, the Netherlands.This increase was steady over time and was not affected by the COVID-19 pandemic.Consultation rates in general practice for psychosocial problems increased most strongly in adolescent girls and young women.

Reasons for unsuccessful recruitment of children with atopic dermatitis in primary care in the Netherlands to a cohort study with an embedded pragmatic, randomised controlled open-label trial: a survey.

BACKGROUND: The Rotterdam Eczema Study was an observational cohort study with an embedded pragmatic randomised controlled open-label trial. It was conducted in children with atopic dermatitis (AD) in the Dutch primary care system. The objective of the trial was to determine whether a potent topical corticosteroid (TCS) is more effective than a low-potency TCS. OBJECTIVE: We are aiming to communicate transparently about the poor recruitment for the trial part and to explore the reasons why recruitment was weak. DESIGN: We used a survey to find out what patients in the cohort did when they experienced a flare-up. METHODS: Descriptive statistics were used to present the baseline characteristics of participants in the trial and the results of the survey. RESULTS: In total, 367 patients were included in the cohort. Of these, 32 were randomly assigned to a trial treatment; they had a median age of 4.0 years (IQR 2.0-9.8). A total of 69 of the 86 children (80.2%) who could participate in the survey responded. 39 (56.5%) suffered a flare-up during the follow-up (making them potentially eligible for inclusion in the trial). 26 out of 39 (66.7%) increased their use of an emollient and/or TCS themselves. Only 12 of the 39 (30.7%) contacted their general practitioner (GP) as instructed in the study protocol, but 8 out of these 12 did not meet the inclusion criteria for the trial. CONCLUSION: The main reason why cohort participants did not take part in the trial was that they did not contact their GPs when they experienced an AD flare-up. Furthermore, the majority of patients who contacted their GPs did not match the inclusion criteria of the trial. We expect that the lessons learnt from this study will be useful when developing future studies of children with AD in primary care.

Air pollution and childhood respiratory consultations in primary care: a systematic review.

BACKGROUND: Outdoor air pollution is a known risk factor for respiratory morbidity worldwide. Compared with the adult population, there are fewer studies that analyse the association between short-term exposure to air pollution and respiratory morbidity in children in primary care. OBJECTIVE: To evaluate whether children in a primary care setting exposed to outdoor air pollutants during short-term intervals are at increased risk of respiratory diagnoses. METHODS: A search in Medline, the Cochrane Library, Web of Science and Embase databases throughout March 2023. Percentage change or risk ratios with corresponding 95% CI for the association between air pollutants and respiratory diseases were retrieved from individual studies. Risk of bias assessment was conducted with the Newcastle-Ottawa Scale (NOS) for cohort or case-control studies and an adjusted NOS for time series studies. RESULTS: From 1366 studies, 14 were identified as meeting the inclusion criteria. Most studies had intermediate or high quality. A meta-analysis was not conducted due to heterogeneity in exposure and health outcome. Overall, studies on short-term exposure to air pollutants (carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2) and particulate matter ≤10 µm (PM10)) were associated with increased childhood respiratory consultations in primary care. In general, exposure to ozone was associated with a reduction in respiratory consultations. CONCLUSIONS: The evidence suggests CO, SO2, NO2, PM10 and PM2.5 are risk factors for respiratory diseases in children in primary care in the short term. However, given the heterogeneity of the studies, interpretation of these findings must be done with caution. PROSPERO REGISTRATION NUMBER: CRD42022259279.

Blood pressure measurements for diagnosing hypertension in primary care: room for improvement.

BACKGROUND: In the adult population, about 50% have hypertension, a risk factor for cardiovascular disease and subsequent premature death. Little is known about the quality of the methods used to diagnose hypertension in primary care. OBJECTIVES: The objective was to assess the frequency of use of recognized methods to establish a diagnosis of hypertension, and specifically for OBPM, whether three distinct measurements were taken, and how correctly the blood pressure levels were interpreted. METHODS: A retrospective population-based cohort study using electronic medical records of patients aged between 40 and 70 years, who visited their general practitioner (GP) with a new-onset of hypertension in the years 2012, 2016, 2019, and 2020. A visual chart review of the electronic medical records was used to assess the methods employed to diagnose hypertension in a random sample of 500 patients. The blood pressure measurement method was considered complete if three or more valid office blood pressure measurements (OBPM) were performed, or home-based blood pressure measurements (HBPM), the office- based 30-minute method (OBP30), or 24-hour ambulatory blood pressure measurements (24 H-ABPM) were used. RESULTS: In all study years, OBPM was the most frequently used method to diagnose new-onset hypertension in patients. The OBP-30 method was used in 0.4% (2012), 4.2% (2016), 10.6% (2019), and 9.8% (2020) of patients respectively, 24 H-ABPM in 16.0%, 22.2%, 17.2%, and 19.0% of patients and HBPM measurements in 5.4%, 8.4%, 7.6%, and 7.8% of patients, respectively. A diagnosis of hypertension based on only one or two office measurements occurred in 85.2% (2012), 87.9% (2016), 94.4% (2019), and 96.8% (2020) of all patients with OBPM. In cases of incomplete measurement and incorrect interpretation, medication was still started in 64% of cases in 2012, 56% (2016), 60% (2019), and 73% (2020). CONCLUSION: OBPM is still the most often used method to diagnose hypertension in primary care. The diagnosis was often incomplete or misinterpreted using incorrect cut-off levels. A small improvement occurred between 2012 and 2016 but no further progress was seen in 2019 or 2020. If hypertension is inappropriately diagnosed, it may result in under treatment or in prolonged, unnecessary treatment of patients. There is room for improvement in the general practice setting.

Atopic Dermatitis in Children in the General Population: Baseline Characteristics, Medication Use, and Severity Measures in the Rotterdam Eczema Study.

Background: Real-life data on severity and treatments in children with atopic dermatitis (AD) are needed to evaluate self-management. Objectives: To determine severity and use of topical treatments in children with AD in the general population. Furthermore, we aim to determine agreement and correlation between objective and subjective AD severity measures. Methods: Data were used from the Rotterdam Eczema Study, an observational prospective cohort study with an embedded pragmatic open-label randomized controlled trial. Descriptive statistics were used for baseline characteristics, medication use, and severity. Strength of agreement and correlation were determined using kappa analysis and Pearson correlation. Results: In total, 367 children (mean age 5.7 years) were recruited. The mean eczema area and severity index (EASI) score was 2.1 (±3.2) and mean patient-oriented eczema measure (POEM) score was 10.3 (±6.1). The majority applied emollients on a daily basis (54.9%) and had not used topical corticosteroids (TCSs) over the past week (51%). Based on severity banding of POEM and EASI, 49.9% and 24.9% of the children were undertreated, respectively. No evidence was found for an agreement between EASI and POEM (kappa 0.028, n = 178, P = 0.451). A moderate correlation between POEM, EASI, infants' dermatitis quality of life index, and children's dermatology life quality index was found. POEM showed higher correlation with quality of life (QoL) than EASI. Conclusion: Emollients were used sufficiently in the study population. Based on signs or symptoms, 24.9% and 49.9% of children are undertreated, respectively. POEM scores correlated better with QoL than with EASI scores. We argue that EASI underestimates severity of AD, and treatment based on EASI scores may lead to undertreatment of AD. Treating physicians should be aware of suboptimal use of TCSs.

Lessons from the Netherlands for Australia: cross-country comparison of trends in antidepressant dispensing 2013-2021 and contextual factors influencing prescribing.

BACKGROUND: There is concern internationally about increasing antidepressant use. Most antidepressants are prescribed in general practice. The aim of this study was to compare trends in antidepressant dispensing in Australia and the Netherlands over the 9years from 2013 to 2021, and to explore reasons for differences. METHODS: A convergent mixed methods study including analysis of publicly available antidepressant dispensing data obtained from Australia's Pharmaceutical Benefits Scheme and Repatriation Pharmaceutical Benefits Scheme and the Dutch Foundation for Pharmaceutical Statistics and a search of relevant literature to compare contextual factors influencing prescribing were undertaken. RESULTS: In 2013, antidepressant dispensing rates in Australia were nearly twice as high as those in the Netherlands (82.5 versus 44.3DDD/1000/day) and increased to be more than twice as high by 2021 (115.6 versus 48.8DDD/1000/day). Antidepressant dispensing increased by 40% in Australia over the nine study years, but by only 10% in the Netherlands. Our scan of the literature confirms that while population factors, health system structure, and clinical guideline recommendations are largely consistent across the two countries, a multifaceted approach in the Netherlands involving improved access to non-pharmacological alternatives, initiatives targeting safer antidepressant prescribing, and tight regulation of pharmaceutical industry influence on prescribers, has successfully curtailed increasing antidepressant use. CONCLUSIONS: Australia may learn from the Netherlands' approach to redress increasing antidepressant use.

A systematic review of questionnaires measuring asthma control in children in a primary care population.

Several questionnaires are used to measure asthma control in children. The most appropriate tool for use in primary care is not defined. In this systematic review, we evaluated questionnaires used to measure asthma control in children in primary care and determined their usefulness in asthma management. Searches were performed in the MEDLINE, Embase, Web of Science, Google Scholar and Cochrane databases with end date 24 June 2022. The study population comprised children aged 5-18 years with asthma. Three reviewers independently screened studies and extracted data. The methodological quality of the studies was assessed, using the COSMIN criteria for the measurement properties of health status questionnaires. Studies conducted in primary care were included if a minimum of two questionnaires were compared. Studies in secondary or tertiary care and studies of quality-of-life questionnaires were excluded. Heterogeneity precluded meta-analysis. Five publications were included: four observational studies and one sub-study of a randomized controlled trial. A total of 806 children were included (aged 5-18 years). We evaluated the Asthma Control Test (ACT), childhood Asthma Control Test (c-ACT), Asthma APGAR system, NAEPP criteria and Royal College of Physicians' '3 questions' (RCP3Q). These questionnaires assess different symptoms and domains. The quality of most of the studies was rated 'intermediate' or 'poor'. The majority of the evaluated questionnaires do not show substantial agreement with one another, which makes a comparison challenging. Based on the current review, we suggest that the Asthma APGAR system seems promising as a questionnaire for determining asthma control in children in primary care.

Clinical response to varying pollen exposure in allergic rhinitis in children in The Netherlands.

BACKGROUND: Allergic rhinitis (AR) affects 10-15% of children. Symptoms in seasonal AR are influenced by pollen exposure. Pollen counts vary throughout the pollen season and therefore, symptom severity fluctuates. This study investigates the correlation between pollen concentration and symptom load in children with AR in The Netherlands. METHODS: A secondary analysis was performed in a study determining the most effective treatment for children with seasonal AR. Symptoms were measured during three months in 2013 and 2014 using a daily symptom diary. The pollen concentration was measured with a Hirst type volumetric spore trap sampler. A correlation coefficient was calculated for the correlation between the pollen concentration and the mean daily symptom score. The study protocol was approved by the medical ethical review committee of the Erasmus MC and is incorporated in the International Clinical Trials Registry Platform (EUCTR2012-001,591-11-NL). RESULTS: In 2014, the correlation coefficient for birch pollen concentration and symptom score was 0.423 (p = 0.000). The correlation coefficient for grass pollen concentration and symptom score was 0.413 (p = 0.000) and 0.655 (p = 0.000) in 2013 and 2014, respectively. A delayed correlation between the birch pollen concentration and the symptom scores was seen up to two days after the pollen measurement (0.151, p = 0.031). For grass pollen this effect lasted up to three days after the pollen measurement (0.194, p = 0.000). CONCLUSION: We found comparable correlations between symptom score and pollen concentration as found by EAACI. Birch and grass pollen have an elongated influence on symptom score of several days. This implies patients need to continue on demand medication longer after a measured pollen peak.

GPs' and practice nurses' views on their management of paediatric anxiety problems: an interview study.

BACKGROUND: Anxiety problems are common in both children and adolescents, and many affected children do not receive appropriate treatment. Understaffing of mental healthcare services and long waiting lists form major barriers. In the Netherlands, practice nurses have been introduced into general practice to support general practitioners (GPs) in the management of psychosocial problems. In this study we investigated the views of GPs and practice nurses on their management of paediatric anxiety problems. METHODS: We performed an exploratory study using semi-structured interviews with 13 GPs and 13 practice nurses in the greater Rotterdam area in 2021. Interviews were transcribed and coded into topics, which were categorized per research question. RESULTS: In their management of paediatric anxiety problems, both GPs and practice nurses try to explore the case and the needs of affected children and their parents. GPs rarely follow up affected children themselves. They often refer the child, preferably to their practice nurse. Practice nurses regularly initiate follow-up consultations with affected children themselves. Practice nurses reported using a variety of therapeutic techniques, including elements of cognitive behavioural therapy. In more severe cases, practice nurses refer the child to external mental healthcare services. GPs reported being satisfied with their collaboration with practice nurses. Both GPs and practice nurses experience significant barriers in the management of paediatric anxiety problems. Most importantly, long waiting lists for external mental health care were reported to be a major difficulty. Improving cooperation with external mental healthcare providers was reported to be an important facilitator. CONCLUSIONS: In their management of paediatric anxiety problems, GPs and practice nurses experience major challenges in the cooperation with external mental healthcare providers and in the long waiting lists for these services. GPs and practice nurses believe that thanks to their shared approach more children with anxiety problems can remain treated in general practice. Future research is needed to evaluate the treatment outcomes of the shared efforts of GPs and practice nurses in their management of paediatric anxiety problems.

General practitioners' explanation and advice on childhood eczema and factors influencing their treatment strategy: A qualitative study.

Background: Atopic dermatitis (AD) is common in children and the majority of children can be treated by the general practitioner (GP). Various factors can influence the GP's treatment strategy and may lead to less effective treatment. The objective is to gain insight into the treatment goal, treatment strategy, explanation and advice given by GPs when dealing with AD in children and to explore which factors play a role in the choice of pharmacological treatment. Methods: Semi-structured interviews in primary care in the Netherlands were audio-recorded and transcribed. All data were analysed according to the six-steps approach of inductive thematic analysis. Results: We interviewed 16 GPs. Treatment goals mainly focussed on the short term. GPs discussed the importance of emollient use and emphasised emollients as the basis of treatment. We found that several factors played a role in prescribing topical corticosteroids (TCS); severity of the AD, age of the child, skin type, corticophobia among parents and GPs, experience of side effects and dermatological experience. GPs reported giving limited advice about the use of TCS and prescribed medication that is not recommended by the guideline. Conclusion: Various factors seem to influence GPs' treatment strategy for AD in children. More attention and education about the use and safety of TCS in children during GP training, continuous medical education, probably improve treatment in line with guidelines and can lead to more confidence and knowledge about TCS among GPs, which ultimately may improve the education and self-management of patients.

Anxiety problems in children and adolescents: a population-based cohort study on incidence and management in Dutch primary care.

BACKGROUND: Due to a large strain on youth mental health care, general practice is suggested as an alternative treatment setting for children and adolescents with anxiety problems. However, research on the current management of these children and adolescents within general practice is scarce. AIM: To investigate the incidence of coded anxiety in general practice using the International Classification of Primary Care (ICPC), and GPs' management of children and adolescents presenting with anxiety problems. DESIGN AND SETTING: Population-based cohort study using electronic medical records of 51 212 children (aged 0-17 years) in primary care in the Rotterdam region between 1 January 2012 and 31 December 2018. METHOD: Incidence of ICPC codes for anxiety were calculated, then the characteristics of children and adolescents consulting their GP with anxiety and the GPs' management were assessed qualitatively using quantitative content analysis. RESULTS: Incidence of ICPC codes for anxiety in children and adolescents was 5.36 (95% confidence interval [CI] = 5.02 to 5.71) per 1000 person-years. Adolescent females had the highest incidence with 14.01 (95% CI = 12.55 to 15.58) per 1000 person-years. Of the 381 children and adolescents consulting their GP with an initial anxiety problem (median age 13.3 years, 40.4% male), GPs referred 59.3% to mental health care in the first year while 26.5% of children and adolescents were managed by a specialised practice nurse within general practice. Of the 381 children and adolescents, 10.5% received psychiatric medication during the first year, with the trend being for increased prescriptions during adolescence. CONCLUSION: In general practice children and adolescents frequently received one of two ICPC codes for anxiety, especially adolescent females. Most presenting to their GP with anxiety problems are referred externally or seen by a specialised practice nurse within general practice.

Developing clinical prediction models for nonrecovery in older patients seeking care for back pain: the back complaints in the elders prospective cohort study.

ABSTRACT: Back pain is a leading cause of disability worldwide and is common in older adults. No clinical prediction models for poor long-term outcomes have been developed in older patients with back pain. This study aimed to develop and internally validate 3 clinical prediction models for nonrecovery in this population. A prospective cohort study in general practice was conducted (Back Complaints in the Elders, Netherlands), including 675 patients >55 years with a new episode of care for back pain. Three definitions of nonrecovery were used combining 6-month and 12-month follow-up data: (1) persistent back pain, (2) persistent disability, and (3) perceived nonrecovery. Sample size calculation resulted in a maximum of 14 candidate predictors that were selected from back pain prognostic literature and clinical experience. Multivariable logistic regression was used to develop the models (backward selection procedure). Models' performance was evaluated with explained variance (Nagelkerke's R2), calibration (Hosmer-Lemeshow test), and discrimination (area under the curve [AUC]) measures. The models were internally validated in 250 bootstrapped samples to correct for overoptimism. All 3 models displayed good overall performance during development and internal validation (ie, R2 > 30%; AUC > 0.77). The model predicting persistent disability performed best, showing good calibration, discrimination (AUC 0.86, 95% confidence interval 0.83-0.89; optimism-adjusted AUC 0.85), and explained variance (R2 49%, optimism-adjusted R2 46%). Common predictors in all models were: age, chronic duration, disability, a recent back pain episode, and patients' recovery expectations. Spinal morning stiffness and pain during spinal rotation were included in 2 of 3 models. These models should be externally validated before being used in a clinical primary care setting.

Natural History of Back Pain in Older Adults over Five Years.

INTRODUCTION: Back pain is a prevalent health problem. Research often focuses on adults. Evidence on the long-term course of back pain in older patients is limited. A prospective cohort study (BACE) was conducted in a primary care setting in the Netherlands. We aim to investigate the 5-year course and medical consumption of older adults (>55 years) presenting with back pain in general practice. METHODS: Patients aged >55 years, consulting their general practitioner with a new back pain episode, were included between 2009 to 2011. Follow-up questionnaires included, for example, pain severity, disability, quality of life, recovery, and medical consumption. RESULTS: A total of 675 patients (mean age ± SD, 66.4 ± 7.6 years) participated, showing a mean (± SD) back pain reduction from 5.2 (± 2.7) to 3.6 (± 2.8) (numeric rating scale, 0 to 10) at 3 months follow-up; disability decreased from 9.8 (± 5.8) to 7.8 (± 6.2) (Roland-Morris Disability Questionnaire, 0 to 24). After 6 months, this remained practically constant over time. Medical consumption was highest in the first months; medication was used by 72% at baseline and approximately one-third (25% to 39%) during follow-up. At 5-year follow-up (response rate 58%; n = 392), 43% had recovered; a majority reported persistent or recurrent back pain. CONCLUSION: Clinically relevant improvements in back pain intensity and disability were seen in the first 3 to 6 months of follow-up. A majority of patients does not become pain free within 3 months; this does not improve over 5 years. However, most patients stop consulting health care professionals during follow-up. Current medical strategies may not be sufficient in older back pain patients, where back pain becomes a recurrent or chronic condition in the majority of patients.

Protocolled practice nurse-led care for children with asthma in primary care: protocol for a cluster randomised trial.

INTRODUCTION: In children with asthma, daily symptoms and exacerbations have a significant impact on the quality of life of both children and parents. More effective use of asthma medication and, consequently, better asthma control is advocated, since both overtreatment and undertreatment are reported in primary care. Trials in adults suggest that asthma control is better when patients receive a regular medical review. Therefore, protocolled care by the general practitioner may also lead to better asthma control in children. However, such protocolled care by the general practitioner may be time consuming and less feasible. Therefore, this study aims to determine whether protocolled practice nurse-led asthma care for children in primary care provides more effective asthma control than usual care. METHODS AND ANALYSIS: The study will be a cluster-randomised open-label trial with an 18-month follow-up. Practice nurses will be the units of randomisation and children with asthma the units of analysis. It is planned to include 180 children aged 6-12 years. Primary outcome will be average asthma control during the 18-month follow-up measured by the Childhood Asthma Control Test (C-ACT). Secondary outcomes include C-ACT scores at t=3, t=6, t=12 and t=18 months; the frequency and severity of exacerbations; cost-effectiveness; quality of life; satisfaction with delivered care; forced expiratory volume in 1 s and forced expiratory flow at 75% and the association of high symptoms scores at baseline and baseline characteristics. Besides, we will conduct identical measurements in a non-randomised sample of children. ETHICS AND DISSEMINATION: This will be the first trial to evaluate the effectiveness of protocolled practice nurse-led care for children with asthma in primary care. The results may lead to improvements in asthma care for children and can be directly implemented in revisions of asthma guidelines.The study protocol was approved by the Medical Research Ethics Committee of the Erasmus Medical Centre in Rotterdam. TRIAL REGISTRATION: NTR6847.

Different potencies of topical corticosteroids for a better treatment strategy in children with atopic dermatitis (the Rotterdam Eczema study): protocol for an observational cohort study with an embedded randomised open-label controlled trial.

INTRODUCTION: Topical corticosteroids (TCS) of different potencies are the main treatment to control atopic dermatitis (AD). The Dutch guideline on AD for general practitioners (GPs) recommends a stepwise approach in which treatment steps are tailored to the severity of the disease, starting with the lowest possible potency of TCS. However, it remains unclear whether the recommended stepwise approach is most efficient. This randomised open-label controlled trial aims to determine whether a potent TCS is more effective than a low-potency TCS in the initial treatment of children with a moderate flare-up of AD in primary care. In the observational cohort, the overall aim is to determine the frequency, burden and determinants of flare-ups of AD during follow-up. METHODS AND ANALYSIS: The study is an observational cohort study with an embedded pragmatic randomised controlled, open-label trial. Eligible are patients diagnosed with AD (aged 12 weeks to 18 years) who visited the GP for AD or received repeated prescriptions for AD in the previous 12 months; follow-up of the cohort is 1 year. Children are enrolled in the trial if they have a flare-up of AD during follow-up in the cohort. Eligible children are randomised to the intervention group (with a potent TCS once daily) or to the GP guideline group (with a low potency TCS once daily). Primary outcome is the difference in average subjective disease severity over 24 weeks follow-up in the trial, measured with the patient-oriented eczema measure. As secondary outcome, the Eczema Area and Severity Index is measured. ETHICS AND DISSEMINATION: This study tests the hypothesis that immediate treatment with a potent TCS during a flare-up of AD leads to faster and more efficacious results as compared with starting with a TCS with low potency with less overall use of TCS. The study protocol is approved by the Medical Ethics Committee (MEC) of the Erasmus Medical Center Rotterdam, the Netherlands (MEC-2017-328). The results of the study will be published in international peer-reviewed journals and presented at national and international conferences. TRIAL REGISTRATION NUMBER: NTR: 6679; Pre-results.

Patient Characteristics and General Practitioners' Advice to Stop Statins in Oldest-Old Patients: a Survey Study Across 30 Countries.

BACKGROUND: Statins are widely used to prevent cardiovascular disease (CVD). With advancing age, the risks of statins might outweigh the potential benefits. It is unclear which factors influence general practitioners' (GPs) advice to stop statins in oldest-old patients. OBJECTIVE: To investigate the influence of a history of CVD, statin-related side effects, frailty and short life expectancy, on GPs' advice to stop statins in oldest-old patients. DESIGN: We invited GPs to participate in this case-based survey. GPs were presented with 8 case vignettes describing patients > 80 years using a statin, and asked whether they would advise stopping statin treatment. MAIN MEASURES: Cases varied in history of CVD, statin-related side effects and frailty, with and without shortened life expectancy (< 1 year) in the context of metastatic, non-curable cancer. Odds ratios adjusted for GP characteristics (ORadj) were calculated for GPs' advice to stop. KEY RESULTS: Two thousand two hundred fifty GPs from 30 countries participated (median response rate 36%). Overall, GPs advised stopping statin treatment in 46% (95%CI 45-47) of the case vignettes; with shortened life expectancy, this proportion increased to 90% (95CI% 89-90). Advice to stop was more frequent in case vignettes without CVD compared to those with CVD (ORadj 13.8, 95%CI 12.6-15.1), with side effects compared to without ORadj 1.62 (95%CI 1.5-1.7) and with frailty (ORadj 4.1, 95%CI 3.8-4.4) compared to without. Shortened life expectancy increased advice to stop (ORadj 50.7, 95%CI 45.5-56.4) and was the strongest predictor for GP advice to stop, ranging across countries from 30% (95%CI 19-42) to 98% (95% CI 96-99). CONCLUSIONS: The absence of CVD, the presence of statin-related side effects, and frailty were all independently associated with GPs' advice to stop statins in patients aged > 80 years. Overall, and within all countries, cancer-related short life expectancy was the strongest independent predictor of GPs' advice to stop statins.

Increased healthcare utilisation among atopic children in a general practice database: a nested index-control study.

BACKGROUND: Atopic eczema, asthma, and allergic rhinitis (AR) create a serious burden on general practice resources. AIM: To investigate the use of general practice resources (that is, consultation visits, telephone contacts, and home visits) in children with physician-diagnosed atopic disorders (ADs). DESIGN & SETTING: In a nested index-control study design, all children (here defined as individuals aged 2-18 years) listed in a representative general practice database were selected in 2014. METHOD: Children diagnosed with ADs were matched on age and sex with non-atopic controls within the same practice. For all the different groups, the number and frequency of children contacting the GP were calculated. RESULTS: Of the children with atopic eczema (n = 15 202), 80% consulted the GP in 2014 (controls = 67%). Of the children with asthma (n = 7754), 80% consulted the GP (controls = 65%), and for children with AR (n = 6710), this was 82% (controls = 66%). Of the children with all three ADs, 91% consulted the GP (controls = 68%). On average, a child with atopic eczema contacted the GP 2.8 times/year (controls = 1.9); for children with asthma, the contact frequency was 3.0 (controls = 1.9); and for AR, 3.2 (controls = 1.9). For children with all three ADs, the contact frequency was 4.3 (controls = 2.0). Consultations related to the ADs investigated only explain a smaller part of the increased healthcare utilisation in atopic children. CONCLUSION: Atopic children use more general practice resources compared to non-atopic children, yet frequently for morbidity or other health-related questions not related to one of the ADs.
