General practitioners' and community pharmacists' beliefs and practices on opioids for non-malignant pain.

BACKGROUND: In Europe, opioid use has surged, largely due to prescriptions for chronic non-malignant pain (CNMP). General practitioners (GPs) and community pharmacists (CPs) play a major role in opioid prescribing for non-malignant pain. Exploring their personal beliefs and practices might reveal underlying mechanisms to identify measures that could halt the further escalation of opioid use. METHODS: Guided by the health belief model, a survey was designed and distributed nationwide to examine the practices and beliefs of GPs and CPs in the domains: threats, benefits, barriers and self-efficacy. The results of GPs and CPs were compared at the statement level using chi-square analysis. RESULTS: Of 214 GPs and 212 CPs who completed the survey, the majority agreed that too many opioids are used in the treatment of chronic non-malignant pain (66.8% GPs and 66.5% CPs). Furthermore, they were concerned about the addictive potential of opioids (83.1% GPs and 71.7% CPs). In general, both professions have concerns about opioid use. GPs report a slightly higher degree of self-efficacy and perceive fewer benefits from opioids in treating CNMP. GPs and CPs valued the recommended measures to reduce opioid prescribing, yet less than half actively implement these strategies in their clinics. CONCLUSION: GPs and CPs believe that opioids are being used too frequently to treat CNMP. However, both professions lack the actions to improve opioid-related care. GPs and CPs require education, collaboration and tools to implement guidelines on non-malignant pain and opioids. SIGNIFICANCE: This study, guided by the health belief model, reveals that general practitioners and community pharmacists have serious concerns about opioid use in chronic non-malignant pain. Despite shared concerns, both professions differ in their beliefs about opioid benefits and perceived self-efficacy. Both professions have in common that they value recommended measures to reduce opioid prescribing. Also, they both struggle to implement strategies, emphasizing the urgent need for education, collaboration and tools to align practices with guidelines on non-malignant pain and opioids.

Determinants of and interventions for Proton Pump Inhibitor prescription behavior: A systematic scoping review.

BACKGROUND: Proton Pump Inhibitors (PPI) are frequently prescribed. Long-term use is associated with side-effects and patients often lack a valid indication. Inappropriate PPI prescribing thus needs to be addressed. This review aims to scope 1) what determinants are studied as reasons for PPI prescribing, 2) what strategies are used for changing PPI (de)prescribing, and 3) whether important determinants are addressed in these interventions. METHODS: We searched eight databases for papers on determinants of physician PPI prescribing. Studies were included if they were conducted in a Western country and focused on oral PPIs for an adult population. By following the Behaviour Change Wheel, we extracted information regarding PPI prescribing behavior, behavioral determinants and intervention strategies. FINDINGS: We included 74 papers. Most focused on the determinants knowledge and beliefs about consequences. The latter was consistently related to PPI prescribing. Results for knowledge were mixed. Most interventions used education or enablement (e.g., algorithms, quality check improvements, involvement of pharmacists) as strategies. Enablement consistently improved PPI prescribing, while results for education were mixed. INTERPRETATION: There is an overemphasis on reflective processes in studies on PPI prescribing. Future research should comprehensively identify behavioral determinants, focusing on reflective and impulsive processes, such that interventions can address the most important determinants.

The introduction of a data-driven population health management approach in the Netherlands since 2019: The Extramural LUMC Academic Network data infrastructure.

Improving population health and reducing inequalities through better integrated health and social care services is high up on the agenda of policymakers internationally. In recent years, regional cross-domain partnerships have emerged in several countries, which aim to achieve better population health, quality of care and a reduction in the per capita costs. These cross-domain partnerships aim to have a strong data foundation and are committed to continuous learning in which data plays an essential role. This paper describes our approach towards the development of the regional integrative population-based data infrastructure Extramural LUMC (Leiden University Medical Center) Academic Network (ELAN), in which we linked routinely collected medical, social and public health data at the patient level from the greater The Hague and Leiden area. Furthermore, we discuss the methodological issues of routine care data and the lessons learned about privacy, legislation and reciprocities. The initiative presented in this paper is relevant for international researchers and policy-makers because a unique data infrastructure has been set up that contains data across different domains, providing insights into societal issues and scientific questions that are important for data driven population health management approaches.

The impact of the covid-19 pandemic on diabetes care: the perspective of healthcare providers across Europe.

AIMS: Covid-19 caused changes on the delivery of diabetes care. This study aimed to explore perceptions of healthcare providers across Europe concerning 1) the impact of covid-19 on delivery of diabetes care; 2) impact of changes in diabetes care on experienced workload; 3) experiences with video consultation in diabetes care. METHODS: Cross-sectional survey among healthcare providers in the Netherlands, United Kingdom, Turkey, Ukraine and Sweden, with a focus on primary care. RESULTS: The survey was completed by 180 healthcare providers. During the COVID-19 pandemic 57.1% of respondents provided less diabetes care and 72.8% observed a negative impact on people with diabetes. More than half of respondents (61.9%) expressed worries to some extent about getting overloaded by work. Although the vast majority considered their work meaningful (85.6%). Almost half of healthcare providers (49.4%) thought that after the pandemic video-consultation could be blended with face-to-face contact. CONCLUSIONS: Less diabetes care was delivered and a negative impact on people with diabetes was observed by healthcare providers. Despite healthcare providers' feeling overloaded, mental wellbeing seemed unaffected. Video consultations were seen as having potential. Given the remaining covid-19 risks and from the interest of proactive management of people with diabetes, these findings urge for further exploration of incorporating video consultation in diabetes care.

Informative value of referral letters from general practice for child and adolescent mental healthcare.

Although referral letters (RLs) form a nodal point in a patient's care journey, little is known about their informative value in child and adolescent mental healthcare. To determine the informative value of RLs to child and adolescent psychiatry, we conducted a chart review in medical records of minors registered at specialized mental healthcare between January 2015 and December 2017 (The Netherlands). Symptoms indicated in RLs originating from general practice (N = 723) were coded and cross-tabulated with the best estimate clinical classifications made in psychiatry. Results revealed that over half of the minors in the sample were classified in concordance with at least one reason for referral. We found fair to excellent discriminative ability for indications made in RLs concerning the most common psychiatric classifications (95% CI AUC: 60.9-70.6 for anxiety disorders to 90.5-100.0 for eating disorders). Logistic regression analyses suggested no statistically significant effects of gender, age, severity or mental healthcare history, with the exception of age and attention deficit hyperactivity disorders (ADHD), as RLs better predicted ADHD with increasing age (OR = 1.14, 95% CI 1.03-1.27). Contextual problems, such as difficulties studying, problems with parents or being bullied were indicated frequently and associated with classifications in various disorder groups. To conclude, general practitioners' RLs showed informative value, contrary to common beliefs. Replication studies are needed to reliably incorporate RLs into the diagnostic work-up.

Caffeine Consumption and Behavioral Symptoms in Nursing Home Residents: A Cross-Sectional Analysis.

OBJECTIVE: Although behavioral changes are common in nursing home residents with dementia and caffeine is known to influence behavior in healthy adults, the effects of caffeine on the behavior of persons with dementia has received little attention. In this study we assessed the relationship of caffeine and behavioral symptoms in older persons with dementia. DESIGN: A multicenter sub-cohort study embedded in the Elderly Care Physicians (ECP) training program. SETTING: Dutch nursing homes associated with the ECP training program. PARTICIPANTS: A total of 206 individuals with both diabetes and dementia resident in Dutch nursing homes. MEASUREMENTS: Trainee ECPs collected data on caffeine consumption, cognition and behavioral symptoms using the NPI-NH, MDS-DRS and AES-C. Data on factors known to influence behavior in persons with dementia (e.g. marital status, kidney function, urinary tract infection and medication) were also collected. RESULTS: Of the 206 participants, 70% showed behavioral symptoms. An increase in caffeine consumption was associated with a decrease in the presence of behavioral symptoms in the NPI-NH cluster affect and NPI-NH item agitation. Caffeine consumption groups also differed on the presence of disinhibition and depression. In addition, the severity of dementia influenced agitation, anxiety and the clusters affect and psychomotor. CONCLUSION: In a large group of older persons with dementia resident in nursing homes, a low daily consumption of caffeine was associated with greater behavioral symptoms.

Coded diagnoses from general practice electronic health records are a feasible and valid alternative to self-report to define diabetes cases in research.

AIMS: To examine the feasibility and validity of obtaining International Classification of Primary Care (ICPC)-coded diagnoses of diabetes mellitus (DM) from general practice electronic health records for case definition in epidemiological studies, as alternatives to self-reported DM. METHODS: The Netherlands Epidemiology of Obesity study is a population-based cohort study of 6671 persons aged 45-65 years at baseline, included between 2008-2012. Data from electronic health records were collected between 2012-2014. We defined a reference standard using diagnoses, prescriptions and consultation notes and investigated its agreement with ICPC-coded diagnoses of DM and self-reported DM. RESULTS: After a median follow-up of 1.8 years, data from 6442 (97%) participants were collected. With the reference standard, 506 participants (79/1000 person-years) were classified with prevalent DM at baseline and 131 participants (11/1000 person-years) were classified with incident DM during follow-up. The agreement of prevalent DM between self-report and the reference standard was 98% (kappa 0.86), the agreement between ICPC-coded diagnoses and the reference standard was 99% (kappa 0.95). The agreement of incident DM between ICPC-coded diagnoses and the reference standard was >99% (kappa 0.92). CONCLUSIONS: ICPC-coded diagnoses of DM from general practice electronic health records are a feasible and valid alternative to self-reported diagnoses of DM.

The viewing of a 'Bloodcurdling' horror movie increases platelet reactivity: A randomized cross-over study in healthy volunteers.

BACKGROUND: Epidemiological studies have suggested an increased risk of cardiovascular events (CVE) during acute stressful and/or frightful moments. A possible explanation for this could be an effect of acute stress on hemostasis. A recent study demonstrated an increase in factor VIII after watching a horror movie. Primary hemostasis, however, is thought to play a more prominent role in the etiology of CVE. The objective of this study was therefore to assess the influence of viewing a 'bloodcurdling' horror movie on platelet reactivity in healthy volunteers. METHODS: We performed a randomized cross-over study in healthy adults. Subjects were allocated to two movies in random sequence: a horror and a control movie. Blood was drawn at baseline and after 24 min of viewing time. The primary endpoint was the change in Platelet Function Analyzer® Closure Time (Δ PFA-CT) after watching the movie. RESULTS: In total, 20 participants, aged 18-30 years, completed the study protocol. The delta PFA-CT was statistically significantly shorter with a mean in the delta difference of -9.7 s (SEM 4.0, 95% C.I. -18.0 to -1.3) during the horror movie versus the control movie. The Light Transmission Aggregometry endpoints were in line with the PFA-CT, albeit only the highest level of Arachidonic Acid agonist demonstrated a statistically significant mean difference in the delta of aggregation of 13.15% (SEM 7.0, 95% C.I. 1.6-27.9). CONCLUSION: A 'blood curdling' horror movie increases platelet reactivity. These data are supportive of a role of platelet reactivity in acute stress induced cardiovascular event risk.

Myocardial infarction patients referred to the primary care physician after 1­year treatment according to a guideline-based protocol have a good prognosis.

INTRODUCTION: Identifying ST-elevation myocardial infarction (STEMI) patients who can be referred back to the general practitioner (GP) can improve patient-tailored care. However, the long-term prognosis of patients who are returned to the care of their GP is unknown. Therefore, the aim of this study was to assess the long-term prognosis of patients referred back to the GP after treatment in accordance with a 1-year institutional guideline-based protocol. METHODS: All consecutive patients treated between February 2004 up to May 2013 who completed the 1­year institutional MISSION! Myocardial Infarction (MI) follow-up and who were referred to the GP were evaluated. After 1 year of protocolised monitoring, asymptomatic patients with a left ventricular ejection fraction >45% on echocardiography were referred to the GP. Long-term prognosis was assessed with Kaplan-Meier curves and Cox proportional hazards analysis was used to identify independent predictors for 5­year all-cause mortality and major adverse cardiovascular events (MACE). RESULTS: In total, 922 STEMI patients were included in this study. Mean age was 61.6 ± 11.7 years and 74.4% were male. Median follow-up duration after the 1­year MISSION! MI follow-up was 4.55 years (interquartile range [IQR] 2.28-5.00). The event-free survival was 93.2%. After multivariable analysis, age, not using an angiotensin-converting enzyme (ACE) inhibitor/angiotensin-II (AT2) antagonist and impaired left ventricular function remained statistically significant predictors for 5­year all-cause mortality. Kaplan-Meier curves revealed that 80.3% remained event-free for MACE after 5 years. Multivariable predictors for MACE were current smoking and a mitral regurgitation grade ≥2. CONCLUSION: STEMI patients who are referred back to their GP have an excellent prognosis after being treated according to the 1­year institutional MISSION! MI protocol.

Caffeine and neuropsychiatric symptoms in patients with dementia: A systematic review.

BACKGROUND: The consumption of caffeine has well known effects on the behavior and sleep of healthy adults. Behavioral symptoms and sleeping difficulties are common in patients with dementia which may be affected by caffeine consumption. This systematic review examines the association between caffeine intake and neuropsychiatric symptoms in patients with dementia. METHODS: In January 2019 an extensive search was conducted in Medline (PubMed), Embase, Emcare, Cochrane, PsychInfo, Web of Science and gray literature. Studies were included when they: i) investigated patients diagnosed with dementia, ii) reported neuropsychiatric symptoms, iii) used caffeine or coffee consumption as an intervention, and iv) reported associations between caffeine or coffee consumption and neuropsychiatric symptoms. Studies were excluded when they also included participants without a diagnosis of dementia, or presented a review or expert opinion. Two reviewers independently rated the studies and reached consensus on the appraisal. RESULTS: Of the seven studies eligible for this review, four reported on sleeping difficulties and five on behavioral symptoms. There was no consistent effect of caffeine administration on neuropsychiatric symptoms: e.g., both high caffeine consumption and eliminating caffeine were associated with less apathy, the total Neuropsychiatric Inventory (Nursing Home) decreased after both coffee therapy and after eliminating caffeine, and both caffeine consumption and eliminating caffeine improved sleep. CONCLUSION: These findings suggest that caffeine can either induce or reduce neuropsychiatric symptoms in individual patients with dementia. Therefore, in these patients, caffeine consumption requires a prudent individualized approach and further research on the effects of caffeine on individual neuropsychiatric symptoms is required.

PORTALS: design of an innovative approach to anticoagulation management through eHealth.

BACKGROUND: For the monitoring of International Normalized Ratio (INR) values, venous thromboembolism (VTE) and atrial fibrillation (AF) patients can visit anticoagulation clinics, laboratories, or physicians for venous puncture. Point-of-care testing (POCT) made it possible for patients to monitor INR themselves (self-monitoring) and even self-adjust their medication dosage (self-dosage). Both skills are accepted as forms of self-management. eHealth applications can improve this self-management, resulting in better clinical outcomes. METHODS: Our study, called PORTALS, aims at identifying the optimal implementation strategy of training to improve self-management and explore factors that enhance good self-management skills. In addition, the relationship between the implementation strategy of training, clinical outcomes, and individual characteristics will be investigated. Of the 247 recruited participants, 110 chose to continue with regular care. 137 patients have been randomly divided in subgroups and compared using a parallel cohort design: one group will be trained and educated by e-learning, and the other group will receive face-to-face group training. DISCUSSION: More insight in factors that enhance good self-management will help to improve clinical outcomes and patient satisfaction on anticoagulation therapy. Our study will provide practical insights and knowledge of eHealth in daily practice and of the importance of education on the adoption of self-management. We expect the self-management program including training to help patients to better manage their own INR values and medication use, thereby increasing health status and diminishing thromboembolic events and hospitalisation.

e-Vita: design of an innovative approach to COPD disease management in primary care through eHealth application.

BACKGROUND: COPD is a highly complex disease to manage as patients show great variation in symptoms and limitations in daily life. In the last decade self-management support of COPD has been introduced as an effective method to improve quality and efficiency of care, and to reduce healthcare costs. Despite the urge to change the organisation of health care and the potential of eHealth to support this, large-scale implementation in daily practice remains behind, especially in the Netherlands. METHODS/DESIGN: We designed a multilevel study, called e-Vita, to investigate different organisational implementation methods of a self-management web portal to support and empower patients with COPD in three different primary care settings. Using a parallel cohort design, the clinical effects of the web portal will be assessed using an interrupted times series (ITS) study design and measured according to changes in health status with the Clinical COPD Questionnaire (CCQ). The different implementations and net benefits of self-management through eHealth on clinical outcomes will be evaluated from human, organisational, and technical perspectives. DISCUSSION: To our knowledge this is the first study to combine different study designs that enable simultaneous investigation of clinical effects, as well as effects of different organisational implementation methods whilst controlling for confounding effects of the organisational characteristics. We hypothesize that an implementation with higher levels of personal assistance, and integrated in an existing care program will result in increased use of and satisfaction with the platform, thereby increasing health status and diminishing exacerbation and hospitalisation. TRIAL REGISTRATION NUMBER: NTR4098 (31-07-2013).

Primary care management of women with breast cancer-related concerns-a dynamic cohort study using a network database.

The aim of this study was to determine the incidence, management and diagnostic outcomes of breast cancer-related concerns presented in primary care. A dynamic cohort study was performed in the anonymised routine electronic medical records (EMRs) extracted from 49 General Practices in the Netherlands (163,471 person-years, women aged 18-75). Main Outcome Measures were: (1) incidence rates for breast cancer-related concerns in Primary Care, (2) proportions of these women with and without symptoms of the breast referred for further investigation, (3) proportions of referrals (not) according to the guideline and (4) proportions of women with breast cancer-related concerns diagnosed with breast cancer during follow-up. Breast cancer-related concerns are presented frequently in Primary Care (incidence rate 25.9 per 1,000 women annually). About half these women are referred for further investigation. There is room to improve General Practitioner management, mainly for women with an increased lifetime risk of developing breast cancer. Information concerning family history of cancer is often missing in the EMR. Since cancer is rarely diagnosed during follow-up, particularly when symptoms are absent, reduction of unnecessary concerns is plausible if identification of those without an increased risk is improved.

[New side effects of proton pump inhibitors; time for reflection?]. / Nieuwe bijwerkingen van protonpompremmers.

Large population studies published recently have revealed additional risks of chronic use of proton pump inhibitors (PPIs). Dementia and renal failure were reported as long-term follow-up side effects of chronic use, in addition to the previously known increased risk for various infections, osteoporosis and metabolic disturbances. In the light of ongoing over-prescription of PPIs, this should lead to reconsideration of individual indications.

The association between somatization and disability in primary care patients.

BACKGROUND: Patient encounters for medically unexplained physical symptoms are common in primary health care. Somatization ('experiencing and reporting unexplained somatic symptoms') may indicate concurrent or future disability but this may also partly be caused by psychiatric disorders. The aim of this study was to examine the cross-sectional and longitudinal association between somatization and disability in primary care patients with and without anxiety or depressive disorder. METHODS: Data were obtained from 1545 primary care patients, participating in the longitudinal Netherlands Study of Depression and Anxiety (NESDA). Somatization was assessed using the somatization scale of the Four-Dimensional Symptom Questionnaire (4DSQ). Disability was determined by the WHO Disability Assessment Schedule 2.0 (WHO-DAS II). The relationships between somatization and both the total and subdomain scores of the WHO-DAS II were measured cross-sectionally and longitudinally after one year of follow-up using linear regression analysis. We examined whether anxiety or depressive disorder exerted a modifying effect on the somatization-disability association. RESULTS: Cross-sectionally and longitudinally, somatization was significantly associated with disability. Somatization accounted cross-sectionally for 41.8% of the variance in WHO-DAS disability and, longitudinally, for 31.7% of the variance in disability after one year of follow-up. The unique contribution of somatization to disability decreased to 16.7% cross-sectionally and 15.7% longitudinally, when anxiety and/or depressive disorder was added to the model. CONCLUSION: Somatization contributes to the presence of disability in primary care patients, even when the effects of baseline demographic and health characteristics and anxiety or depressive disorder are taken into account.

Validity and reliability of the Katz-15 scale to measure unfavorable health outcomes in community-dwelling older people.

OBJECTIVES: To predict the risk of future unfavourable health outcomes in older people it is common to assess the level of both basic and instrumental activities of daily living. To accomplish this, the commonly used Katz-6 and the Lawton IADL questionnaires can be combined to form the 'Modified Katz ADL' scale, also known as the Katz-15 scale. So far, the validity and reliability of the Katz-15 scale is unknown. The objective of the current study is to investigate how well the Katz-15 is able to predict future unfavorable health outcomes and how this is related to the existing Katz-6 scale. DESIGN: We performed a follow-up study using data from a group of 60 year and older participants from a large Dutch clinical trial. PARTICIPANTS: We included 2321 participants in the analysis. The average age of the study population was 74 years and 44% was male. MEASUREMENTS: We studied the relation between the Katz-15 scale and a number of unfavourable health outcomes, such as hospitalization, admission to a nursing home, admission to a home for the aged and death within one year of follow-up. RESULTS: We found the Katz-15 to be both internally consistent and strongly associated with quality of life measures. We observed moderate to strong associations between the Katz-15 and the unfavourable health outcomes All associations studied were stronger for the Katz-15 scale as compared to the Katz-6 scale. CONCLUSION: The results of our study indicate that the Katz-15 scale is able to reliably and validly predict future unfavorable health outcomes. This makes the scale a valuable measure in determining both basic and instrumental activities of daily living.
