Accuracy of diagnostic tests for acute diverticulitis that are feasible in primary care: a systematic review and meta-analysis.

BACKGROUND: Recognition of acute diverticulitis is important to determine an adequate management strategy. Differentiating it from other gastrointestinal disorders is challenging as symptoms overlap. Clinical tests might assist the clinician with this diagnostic challenge. Previous reviews have focussed on prognostic questions and imaging examinations in secondary care. OBJECTIVE: To evaluate the diagnostic accuracy of clinical tests feasible in primary care for acute diverticulitis in suspected patients. METHOD: We have systematically searched multiple databases for diagnostic accuracy studies of tests feasible in primary care compared to a reference standard in suspected patients. Two reviewers independently selected studies, extracted data, and assessed study quality with the QUADAS-2 tool. We have meta-analysed the results in the case of more than four studies per index test. RESULTS: Seventeen studies were included, all studies were performed in secondary care (median prevalence 48%). Individual signs and symptoms showed a wide range in sensitivity (range 0.00-0.98) and specificity (range 0.08-1.00). Of the four laboratory tests evaluated, CRP >10 mg/l had the highest sensitivity (range 0.89-0.96) with specificity ranging from 0.28 to 0.61. Ultrasound had the highest pooled sensitivity and specificity of 0.92 (95% CI 0.86-0.96) and 0.94 (95% CI 0.88-0.97), respectively. CONCLUSION: None of the studies were performed in primary care. Individual signs and symptoms alone are insufficiently informative for acute diverticulitis diagnosis. CRP showed potential for ruling out and ultrasound had a high diagnostic accuracy. More research is needed about the diagnostic accuracy of these tests in primary care. PROSPERO REGISTRATION NUMBER: CRD42021230622.

Does social need fulfillment moderate the association between socioeconomic status and health risk behaviours during pregnancy?

Socioeconomic differences in health risk behaviours during pregnancy may be influenced by social relations. In this study, we aimed to investigate if social need fulfillment moderates the association between socioeconomic status (SES) and health risk behaviours (smoking and/or alcohol consumption) during pregnancy. We used baseline data from the Lifelines Cohort Study merged with data from the Lifelines Reproductive Origin of Adult Health and Disease (ROAHD) cohort. Education level was used to determine SES, categorized into low, middle, and high, with middle SES as the reference category. Social need fulfillment was taken as indicator for social relations and was measured with the validated Social Production Function Instrument for the Level of Well-being scale. The dependent variable was smoking and/or alcohol consumption during pregnancy. Univariable and multivariable logistic regression analysis was conducted to assess the association of SES and social need fulfillment with health risk behaviours and to test for effect modification. We included 1107 pregnant women. The results showed that women with a high SES had statistically significantly lower odds of health risk behaviours during pregnancy. The interaction effect between SES and social need fulfillment on health risk behaviours was not statistically significant, indicating that no moderation effect is present. The results indicate that social need fulfillment does not modify the effect of SES on health risk behaviours during pregnancy. However, in literature, social relations are identified as an important influence on health risk behaviours. More research is needed to identify which measure of social relations is the most relevant regarding the association with health risk behaviours.

Acute Gastroenteritis: A Qualitative Study of Parental Motivations, Expectations, and Experiences During Out-of-Hours Primary Care.

PURPOSE: Acute gastroenteritis is a common infectious disease in children younger than 6 years of age. Although it is a self-limiting disease, it nevertheless has a high consultation rate in primary care, especially during out-of-hours primary care (OOH-PC). Reasons for this high consultation rate remain unclear. METHODS: The aim of this qualitative study was to explore parental motivations, expectations, and experiences of OOH-PC contacts for children with acute gastroenteritis. We conducted 14 semistructured interviews with parents who contacted OOH-PC in the Netherlands. Interviews were audio-recorded, transcribed, and analyzed using elements of grounded theory and a constant-comparison approach. RESULTS: Unusual behavior of the sick child, absent micturition, and ongoing vomiting and/or diarrhea, with decreased or no fluid intake, motivated parents to contact OOH-PC. Parents initiated contact to prevent symptom deterioration and to be reassured by a general practitioner (GP), expecting them to perform a thorough physical examination, provide information, and make follow-up plans. Parents reported dissatisfaction if they felt unheard, misunderstood, or not taken seriously, and this increased their likelihood of seeking another consultation. General practitioners did not always meet parental expectations. CONCLUSION: Multiple factors affect the decision for parents to contact OOH-PC for their child with gastroenteritis. There is a mismatch between parental expectations and actions of the GP. Awareness regarding parental feelings and understanding their expectations can guide GPs in the interaction with parents, which could improve satisfaction with primary health care and OOH-PC specifically.

Cardiovascular risk assessment methods yield unequal risk predictions: a large cross-sectional study in psychiatric secondary care outpatients.

BACKGROUND: Patients with a mental illness are more likely to develop, and die from, cardiovascular diseases (CVD), necessitating optimal CVD-risk (CVR)-assessment to enable early detection and treatment. Whereas psychiatrists use the metabolic syndrome (MetS)-concept to estimate CVR, GPs use absolute risk-models. Additionally, two PRIMROSE-models have been specifically designed for patients with severe mental illness. We aimed to assess the agreement in risk-outcomes between these CVR-methods. METHODS: To compare risk-outcomes across the various CVR-methods, we used somatic information of psychiatric outpatients from the PHAMOUS-, and MOPHAR-database, aged 40-70 years, free of past or current CVD and diabetes. We investigated: (1) the degree-of-agreement between categorical assessments (i.e. MetS-status vs. binary risk-categories); (2) non-parametric correlations between the number of MetS-criteria and absolute risks; and (3) strength-of-agreement between absolute risks. RESULTS: Seven thousand twenty-nine measurements of 3509 PHAMOUS-patients, and 748 measurements of 748 MOPHAR-patients, were included. There was systematic disagreement between the categorical CVR-assessments (all p < 0.036). Only MetS-status versus binary Framingham-assessment had a fair strength-of-agreement (κ = 0.23-0.28). The number of MetS-criteria and Framingham-scores, as well as MetS-criteria and PRIMROSE lipid-scores, showed a moderate-strong correlation (τ = 0.25-0.34). Finally, only the continuous PRIMROSE desk and lipid-outcomes showed moderate strength-of-agreement (ρ = 0.91). CONCLUSIONS: The varying methods for CVR-assessment yield unequal risk predictions, and, consequently, carry the risk of significant disparities regarding treatment initiation in psychiatric patients. Considering the significantly increased health-risks in psychiatric patients, CVR-models should be recalibrated to the psychiatric population from adolescence onwards, and uniformly implemented by health care providers. TRIAL REGISTRATION: The MOPHAR research has been prospectively registered with the Netherlands Trial Register on 19th of November 2014 (NL4779).

Irritable bowel syndrome in children with chronic gastrointestinal symptoms in primary care.

BACKGROUND: Irritable bowel syndrome (IBS) is the most common functional gastrointestinal disorder in children. However, in primary care, it is still unknown whether there are differences in the prognosis of children with IBS compared to other diagnostic subgroups. Therefore, our aim was to describe the course of symptoms and health-related quality of life (HRQoL) for children with chronic gastrointestinal symptoms who either do or do not fulfil the Rome criteria for IBS in primary care. Second, we compared the diagnosis of the general practitioner (GP) with the Rome criteria. METHODS: We conducted a prospective cohort study with 1-year follow-up, including children aged 4-18 years with chronic diarrhoea and/or chronic abdominal pain in primary care. During follow-up, the Rome III questionnaire, Child Health Questionnaire, and symptom questionnaires were completed. RESULTS: A total of 60/104 children (57.7%) fulfilled the Rome criteria for IBS at baseline. Compared to children without IBS, children with IBS were more commonly referred to secondary care, used more laxatives, and more often developed chronic diarrhoea and low physical HRQoL during 1 year. The diagnosis "IBS" from the GP matched the Rome criteria for only 10% of children, as most were diagnosed with "Constipation." CONCLUSIONS: There seems to be a difference in the treatment and prognosis of symptoms and HRQoL between children with and without IBS in primary care. This suggests that it is relevant to differentiate between these groups. The evaluation and use of feasible criteria to define IBS in different healthcare settings remains subject for further studies.

What can we learn from experiences in general practice during the COVID-19 pandemic? A qualitative study.

BACKGROUND: Experiences with organizational changes in daytime general practices and out-of-hours (OOH) services during the COVID-19 pandemic may help to address the challenges in general practice care that were already a concern before the crisis. This study aimed to describe these experiences and the potential usefulness of the organizational changes for future general practice care and any future pandemics. METHODS: Semi-structured interviews were performed among 11 directors of OOH services, and 19 (locum) general practitioners (GPs) or practice managers, who were purposively sampled. Video or telephone interviews were performed in two rounds: between November 2020 and January 2021 and between May 2021 and August 2021. The data were analyzed using thematic analysis methods. RESULTS: Three themes emerged from the data: (1) Changes in the triage procedures; in GP practices and OOH services, stricter triage criteria were implemented, and GPs were more actively involved in the triage process. These measures helped to reduce the number of 'low urgency' face-to-face consultations. (2) Changes in GP care; there was a shift towards video and telephone consultations, allowing GPs to spend more time with patients during the remaining face-to-face consultations. For chronic patients, the shift towards telemonitoring appeared to encourage self-care, and postponing face-to-face consultations for regular checkups appeared to be unproblematic for stable patients. (3) Coordination of GP care and information communication flow during the COVID-19 pandemic; OOH directors perceived a lack of consistency in the information from various governmental and non-governmental parties on containment measures and guidelines related to COVID-19, making it difficult to act on them. The COVID-19 pandemic intensified collaboration between GPs, OOH services, and other healthcare professionals. CONCLUSIONS: The results of this study indicate that some of the organizational changes, such as stricter triage, remote consultations, and changes in managed care of chronic patients, may help in tackling the pre-existing challenges in GP care from before the COVID-19 pandemic. However, more extensive research and continuous monitoring are necessary to establish the effects on patients and their health outcomes. To navigate future pandemics, the intensified collaboration between health professionals should be maintained, while there is considerable room for improvement in the provision of unambiguous information.

Management of children with non-acute abdominal pain and diarrhea in Dutch primary care: a retrospective cohort study based on a routine primary care database (AHON).

OBJECTIVE: To describe the testing, prescription, referral, and follow-up management by general practitioners (GPs) for children presenting with non-acute abdominal pain and/or diarrhea in primary care. DESIGN: Retrospective cohort study with one-year follow-up. SETTING: Registry data from a Dutch primary care database (AHON) between 2015 and 2019. SUBJECTS: Children aged 4-18 years old who presented by face-to-face consultation in primary care for non-acute abdominal pain and/or diarrhea (>7 days). MAIN OUTCOME MEASURES: We recorded the proportions of children who received (1) diagnostic testing, medicine prescriptions, follow-up consultations, and referrals at their first visit and (2) repeat consultations and referrals by one-year of follow-up. RESULTS: Among the 2200 children (median age, 10.5 years; interquartile range, 7.0-14.6) presenting to a GP with non-acute abdominal pain and/or diarrhea, most reported abdominal pain (78.7%). At the first visit, GPs performed diagnostic testing for 32.2%, provided a prescription to 34.5%, and referred 2.5% to secondary care. Twenty-five percent of the children had a follow-up consultation within four weeks and 20.8% had a repeat consultation between four weeks and one year. Thirteen percent of the children were referred to secondary care by one year. However, only 1% of all children had documentation of an organic diagnosis needing management in secondary care. CONCLUSION: One-third of children received diagnostic testing or a medicine prescription. Few had a follow-up consultation and >10% was referred to pediatric care. Future research should explore the motivations of GPs why and which children receive diagnostic and medical interventions.

General practitioners (GPs) often manage children with non-acute abdominal pain and/or diarrhea, which is typically due to a functional gastrointestinal disorder (FGID).Nearly one-third of all children underwent diagnostic testing at their first visit.Although recommended by the guideline of the Dutch Society of GPs, we found that only a quarter of children received a follow-up consultation.Thirteen percent of children were referred to pediatric specialist care by one year.

A Natural Language Processing Model for COVID-19 Detection Based on Dutch General Practice Electronic Health Records by Using Bidirectional Encoder Representations From Transformers: Development and Validation Study.

BACKGROUND: Natural language processing (NLP) models such as bidirectional encoder representations from transformers (BERT) hold promise in revolutionizing disease identification from electronic health records (EHRs) by potentially enhancing efficiency and accuracy. However, their practical application in practice settings demands a comprehensive and multidisciplinary approach to development and validation. The COVID-19 pandemic highlighted challenges in disease identification due to limited testing availability and challenges in handling unstructured data. In the Netherlands, where general practitioners (GPs) serve as the first point of contact for health care, EHRs generated by these primary care providers contain a wealth of potentially valuable information. Nonetheless, the unstructured nature of free-text entries in EHRs poses challenges in identifying trends, detecting disease outbreaks, or accurately pinpointing COVID-19 cases. OBJECTIVE: This study aims to develop and validate a BERT model for detecting COVID-19 consultations in general practice EHRs in the Netherlands. METHODS: The BERT model was initially pretrained on Dutch language data and fine-tuned using a comprehensive EHR data set comprising confirmed COVID-19 GP consultations and non-COVID-19-related consultations. The data set was partitioned into a training and development set, and the model's performance was evaluated on an independent test set that served as the primary measure of its effectiveness in COVID-19 detection. To validate the final model, its performance was assessed through 3 approaches. First, external validation was applied on an EHR data set from a different geographic region in the Netherlands. Second, validation was conducted using results of polymerase chain reaction (PCR) test data obtained from municipal health services. Lastly, correlation between predicted outcomes and COVID-19-related hospitalizations in the Netherlands was assessed, encompassing the period around the outbreak of the pandemic in the Netherlands, that is, the period before widespread testing. RESULTS: The model development used 300,359 GP consultations. We developed a highly accurate model for COVID-19 consultations (accuracy 0.97, F1-score 0.90, precision 0.85, recall 0.85, specificity 0.99). External validations showed comparable high performance. Validation on PCR test data showed high recall but low precision and specificity. Validation using hospital data showed significant correlation between COVID-19 predictions of the model and COVID-19-related hospitalizations (F1-score 96.8; P<.001; R2=0.69). Most importantly, the model was able to predict COVID-19 cases weeks before the first confirmed case in the Netherlands. CONCLUSIONS: The developed BERT model was able to accurately identify COVID-19 cases among GP consultations even preceding confirmed cases. The validated efficacy of our BERT model highlights the potential of NLP models to identify disease outbreaks early, exemplifying the power of multidisciplinary efforts in harnessing technology for disease identification. Moreover, the implications of this study extend beyond COVID-19 and offer a blueprint for the early recognition of various illnesses, revealing that such models could revolutionize disease surveillance.

Cost-effectiveness of an app-based treatment for urinary incontinence in comparison with care-as-usual in Dutch general practice: a pragmatic randomised controlled trial over 12 months.

OBJECTIVE: To assess the cost-effectiveness of app-based treatment for female stress, urgency or mixed urinary incontinence (UI) compared with care-as-usual in Dutch primary care. DESIGN: A pragmatic, randomised controlled, superiority trial. SETTING: Primary care in the Netherlands from 2015 to 2018, follow-up at 12 months. POPULATION: Women with ≥2 UI-episodes per week, access to mobile apps, wanting treatment. METHODS: The standalone app included conservative management for UI with motivation aids (e.g. reminders). Care-as-usual delivered according to the Dutch GP guideline for UI. MAIN OUTCOME MEASURES: Costs and cost-effectiveness and -utility were assessed from a societal perspective, based on incontinence impact adjusted life years (IIALYs), quality adjusted life years (QALYs) and medical, non-medical and productivity costs. Information on costs was obtained with the iMCQ and iPCQ questionnaires (medical consumption and productivity cost questionnaires). RESULTS: In all, 262 women were andomised equally to app or care-as-usual; 89 (68%) and 83 (63%) attended follow-up, respectively. Costs were lower for app-based treatment with € -161 (95% confidence interval [CI -180 to -151) per year. Cost-effectiveness showed small mean differences in effect for IIALY (0.04) and QALY (-0.03) and thus larger incremental cost-effectiveness ratios (ICER: -€3696) and incremental cost-utility ratios (ICUR: €6379). CONCLUSION: App-based treatment is a cost-effective alternative to care-as-usual for women with UI in Dutch primary care. TWEETABLE ABSTRACT: App-treatment for female urinary incontinence cost-effective compared to care-as-usual in general practice after 12 months.

One year effectiveness of an app-based treatment for urinary incontinence in comparison to care as usual in Dutch general practice: A pragmatic randomised controlled trial over 12 months.

OBJECTIVE: To assess the long-term effectiveness of app-based treatment for female stress, urgency or mixed urinary incontinence (UI) compared with care-as-usual in primary care. DESIGN: A pragmatic, randomised controlled, superiority trial. SETTING: Primary care in the Netherlands from 2015 to 2018, follow up at 12 months. POPULATION: Women with two or more UI episodes per week and access to mobile apps, wanting treatment. A total of 262 women were randomised equally to app or care-as-usual; 89 (68%) and 83 (63%) attended 1 year follow up. INTERVENTIONS: The standalone app included conservative management for UI with motivation aids (e.g. reminders). Care-as-usual was delivered according to the Dutch GP guideline for UI. MAIN OUTCOME MEASURES: Effectiveness assessed by the change in symptom severity score (ICIQ-UI-SF) and the change in quality of life (ICIQ-LUTSqol) with linear regression on an intention-to-treat basis. RESULTS: Clinically relevant improvement of UI severity for both app (-2.17 ± 2.81) and care-as-usual (-3.43 ± 3.6) groups, with a non-significant mean difference of 0.903 (-0.66 to 1.871). CONCLUSION: App-based treatment is a viable alternative to care-as-usual for UI in primary care in terms of effectiveness after 1 year. TWEETABLE ABSTRACT: App-based treatment for female urinary incontinence is a viable alternative to care-as-usual after 12 months.

Cost-effectiveness of physiotherapy in childhood functional constipation: a randomized controlled trial in primary care.

OBJECTIVE: Health care expenditures for children with functional constipation (FC) are high, while conservative management is successful in only 50% of the children. The aim is to evaluate whether adding physiotherapy to conventional treatment (CT) is a cost-effective strategy in the management of children with FC aged 4-18 years in primary care. METHODS: A cost-effectiveness analysis was performed alongside a randomized controlled trial (RCT) with 8-month follow-up. Costs were assessed from a societal perspective, effectiveness included both the primary outcome (treatment success defined as the absence of FC and no laxative use) and the secondary outcome (absence of FC irrespective of laxative use). Uncertainty was assessed by bootstrapping and cost-effectiveness acceptability curves (CEACs) were displayed. RESULTS: One hundred and thirty-four children were randomized. The incremental cost-effectiveness ratio (ICER) for one additional successfully treated child in the physiotherapy group compared with the CT group was €24,060 (95% confidence interval [CI] €-16,275 to €31,390) and for the secondary outcome €1,221 (95% CI €-12,905 to €10,956). Subgroup analyses showed that for children with chronic laxative use the ICER was €2,134 (95% CI -24,975 to 17,192) and €571 (95% CI 11 to 3,566), respectively. At a value of €1,000, the CEAC showed a probability of 0.53 of cost-effectiveness for the primary outcome, and 0.90 for the secondary outcome. CONCLUSIONS: Physiotherapy added to CT as first-line treatment for all children with FC is not cost-effective compared with CT alone. Future studies should consider the cost-effectiveness of physiotherapy added to CT in children with chronic laxative use. TRIAL REGISTRATION: The RCT is registered in the Netherlands Trial Register (NTR4797), on the 8th of September 2014. The first child was enrolled on the 2nd of December 2014. https://www.trialregister.nl/trial/4654.

Couple-based expanded carrier screening provided by general practitioners to couples in the Dutch general population: psychological outcomes and reproductive intentions.

PURPOSE: The aim of expanded preconception carrier screening (ECS) is to inform any couple wishing to conceive about their chances of having children with severe autosomal or X-linked recessive conditions. Responsible implementation of ECS as reproductive genetic screening in routine care requires assessment of benefits and harms. We examined the psychological outcomes of couple-based ECS for 50 autosomal recessive (AR) conditions provided by general practitioners (GPs) to couples from the Dutch general population. METHODS: Dutch GPs invited 4,295 women aged 18-40. We examined anxiety (State-Trait Anxiety Inventory, STAI-6), worry, decisional conflict (DCS) over time in participants declining GP counseling or attending GP counseling with/without testing. RESULTS: One hundred ninety couples participated; 130 attended counseling, of whom 117 proceeded with testing. No carrier couples were identified. Before counseling, worry (median 6.0) and anxiety (mean 30-34) were low and lower than the population reference (36.4), although some individuals reported increased anxiety or worry. At follow-up, test acceptors reported less anxiety than test decliners (mean 29 vs. 35); differences in anxiety after testing compared to before counseling were not meaningful. Most participants (90%) were satisfied with their decision (not) to undergo testing. CONCLUSION: Some individuals reported temporarily clinically relevant distress. Overall, the psychological outcomes are acceptable and no barrier to population-wide implementation.

Levonorgestrel-releasing intrauterine system versus endometrial ablation for heavy menstrual bleeding.

BACKGROUND: Heavy menstrual bleeding affects the physical functioning and social well-being of many women. The levonorgestrel-releasing intrauterine system and endometrial ablation are 2 frequently applied treatments in women with heavy menstrual bleeding. OBJECTIVE: This study aimed to compare the effectiveness of the levonorgestrel-releasing intrauterine system with endometrial ablation in women with heavy menstrual bleeding. STUDY DESIGN: This multicenter, randomized controlled, noninferiority trial was performed in 26 hospitals and in a network of general practices in the Netherlands. Women with heavy menstrual bleeding, aged 34 years and older, without a pregnancy wish or intracavitary pathology were randomly allocated to treatment with either the levonorgestrel-releasing intrauterine system (Mirena) or endometrial ablation, performed with a bipolar radiofrequency device (NovaSure). The primary outcome was blood loss at 24 months, measured with a Pictorial Blood Loss Assessment Chart score. Secondary outcomes included reintervention rates, patient satisfaction, quality of life, and sexual function. RESULTS: We registered 645 women as eligible, of whom 270 women provided informed consent. Of these, 132 women were allocated to the levonorgestrel-releasing intrauterine system (baseline Pictorial Blood Loss Assessment Chart score, 616) and 138 women to endometrial ablation (baseline Pictorial Blood Loss Assessment Chart score, 630). At 24 months, mean Pictorial Blood Loss Assessment Chart scores were 64.8 in the levonorgestrel-releasing intrauterine system group and 14.2 in the endometrial ablation group (difference, 50.5 points; 95% confidence interval, 4.3-96.7; noninferiority, P=.87 [25 Pictorial Blood Loss Assessment Chart point margin]). Compared with 14 women (10%) in the endometrial ablation group, 34 women (27%) underwent a surgical reintervention in the levonorgestrel-releasing intrauterine system group (relative risk, 2.64; 95% confidence interval, 1.49-4.68). There was no significant difference in patient satisfaction and quality of life between the groups. CONCLUSION: Both the levonorgestrel-releasing intrauterine system and endometrial ablation strategies lead to a large decrease in menstrual blood loss in women with heavy menstrual bleeding, with comparable quality of life scores after treatment. Nevertheless, there was a significant difference in menstrual blood loss in favor of endometrial ablation, and we could not demonstrate noninferiority of starting with the levonorgestrel-releasing intrauterine system. Women who start with the levonorgestrel-releasing intrauterine system, a reversible and less invasive treatment, are at an increased risk of needing additional treatment compared with women who start with endometrial ablation. The results of this study will enable physicians to provide women with heavy menstrual bleeding with the evidence to make a well-informed decision between the 2 treatments.

App-Based Treatment in Primary Care for Urinary Incontinence: A Pragmatic, Randomized Controlled Trial.

PURPOSE: Electronic application (app)-based treatment is promising for common diseases with good conservative management options, such as urinary incontinence (UI) in women, but its effectiveness compared with usual care is unclear. This study set out to determine if app-based treatment for women with stress, urgency, or mixed UI was noninferior to usual care in the primary care setting. METHODS: The URinControl trial is a pragmatic, noninferiority randomized controlled trial in Dutch primary care including adult women with 2 episodes of UI per week. From July 2015 to July 2018, we screened 350 women for eligibility. A stand-alone app-based treatment with pelvic floor muscle and bladder training (URinControl) was compared with usual care according to the Dutch general practitioner guideline for UI treatment. Outcomes measured were change in symptom severity score from baseline to 4 months (primary outcome), impact on disease-specific quality of life, patient-perceived improvement, and number of UI episodes. Noninferiority (<1.5 points) was assessed with linear regression analysis. RESULTS: A total of 262 eligible women were randomized equally; 195 of them had follow-up through 4 months. The change in symptom severity with app-based treatment (-2.16 points; 95% CI, -2.67 to -1.65) was noninferior to that with usual care (-2.56 points; 95% CI, -3.28 to -1.84), with a mean difference of 0.058 points (95% CI, -0.776 to 0.891) between groups. Neither treatment was superior to the other, and both groups showed improvements in outcome measures after treatment. CONCLUSIONS: App-based treatment for women with UI was at least as effective as usual care in the primary care setting. As such, app-based treatments, with their potential advantages of privacy, accessibility, and lower cost, may provide women with a good alternative to consultation.

Appendicitis in children with acute abdominal pain in primary care, a retrospective cohort study.

BACKGROUND: General practitioners (GPs) face a diagnostic challenge when assessing acute abdominal pain in children. However, no information is available on the current diagnostic process or the diagnostic accuracy of history and physical examination in primary care settings. OBJECTIVE: To describe the diagnostic process for acute abdominal pain among children in primary care, focusing on appendicitis, and to assess the diagnostic accuracy of individual clinical features. METHODS: A retrospective cohort study in Dutch primary care, using the Integrated Primary Care Information database. Children aged 4-18 years were included if they had no history of appendicitis and presented with acute abdominal pain during 2010-2016. We evaluated GP management and the diagnostic accuracy of clinical features for appendicitis. Pre- and post-test probabilities were calculated for each clinical feature and compared with the probability of appendicitis after GP assessment. RESULTS: Out of 5691 children, 944 (16.6%) were referred and 291 (5.1%) had appendicitis, of whom 55 (18.9%) were initially misdiagnosed. The pre-test probability (i.e. of appendicitis in evaluated children) varied from 3% (rigidity) to 28% (migratory pain). Concerning post-test probabilities, positive values for rebound pain (32.1%) and guarding (35.8%) and the negative value for right lower quadrant tenderness (0.6%) were superior to overall GP assessment (29.6% and 1.1%, respectively). CONCLUSIONS: GP assessment will miss almost one-fifth of children with appendicitis at their first presentation, and about two-third of GP referrals will be negative. The presence of specific signs can increase or decrease the likelihood of appendicitis, emphasising the importance of a physical examination.

It can be difficult for general practitioners (GPs) to assess acute abdominal pain in children because they must decide whether it is a common minor problem or an uncommon serious problem. However, unlike their hospital counterparts, GPs must often rely on only the history and examination. We, therefore, wanted to gain a better understanding of how GPs assess abdominal pain and the accuracy of the different parts of their assessment. To do this, we looked back at clinical records for children who presented to a GP with acute abdominal pain between 2010 and 2016. The effect of examination on the probability of detecting appendicitis was calculated for several clinical features, and these were compared with the probability of appendicitis after a full GP assessment. Approximately 1 in 20 of the included children was diagnosed with appendicitis, one in five were initially misdiagnosed, and one in four were ultimately referred to the hospital. We show that some signs and symptoms were not particularly useful for assessment, but when they were, signs detected by the GP examining the patient were more useful than symptoms reported by patients or parents. We recommend that GPs provide safety netting advice and examine the abdomen.

Diagnostic accuracy of follow-up tests for detecting colorectal cancer recurrences in primary care: A systematic review and meta-analysis.

INTRODUCTION: Traditionally, follow-up of colorectal cancer (CRC) is performed in secondary care. In new models of care, the screening part care could be replaced to primary care. We aimed to synthesise evidence on the diagnostic accuracy of commonly used screeners in CRC follow-up applicable in primary care: carcinoembryonic antigen (CEA), ultrasound and physical examination. METHODS: Medline, EMBASE, Cochrane Trial Register and Web of Science databases were systematically searched. Studies were included if they provided sufficient data for a 2 × 2 contingency tables. QUADAS-2 was used to assess methodological quality. We performed bivariate random effects meta-analysis, generated a hypothetical cohort, and reported sensitivity and specificity. RESULTS: We included 12 studies (n = 3223, median recurrence rate 19.6%). Pooled estimates showed a sensitivity for CEA (≤ 5 µg/l) of 59% [47%-70%] and a specificity of 89% [80%-95%]. Only few studies reported sensitivities and specificities for ultrasound (36-70% and 97-100%, respectively) and clinical examination (23% and 27%, respectively). CONCLUSION: In practice, GPs could perform CEA screening. Radiological examination in a hospital setting should remain part of the surveillance strategy. Personalised algorithms accounting for recurrence risk and changes of CEA-values over time might add to the diagnostic value of CEA in primary care.

Physiotherapy for Children with Functional Constipation: A Pragmatic Randomized Controlled Trial in Primary Care.

OBJECTIVE: To determine the effectiveness of physiotherapy plus conventional treatment compared with conventional treatment alone for the treatment of functional constipation in children age 4-17 years in primary care. STUDY DESIGN: Pragmatic randomized controlled trial with 8 months follow-up. Primary care physicians recruited children diagnosed with functional constipation (n = 234), and pediatricians recruited newly referred children with a diagnosis of functional constipation (n = 11). Conventional treatment comprised toilet training, nutritional advice, and laxative prescribing, whereas physiotherapy focused on resolving dyssynergic defecation. The primary outcome was treatment success over 8 months, defined as the absence of functional constipation (Rome III criteria) without laxative use. Secondary outcomes included the absence of functional constipation irrespective of continuation of laxative use and global perceived treatment effect. RESULTS: Children were allocated to conventional treatment plus physiotherapy or conventional treatment alone (67 per group), mean (SD) age was 7.6 (3.5) years. Results of longitudinal analyses in the intention-to-treat population showed that the treatment success percentage was not statistically improved by adding physiotherapy to conventional treatment (adjusted relative risk [aRR] 0.80, 95% CI 0.44-1.30). At 4 months, fewer children receiving physiotherapy had treatment success (17%) than children receiving conventional treatment alone (28%), but this had equalized by 8 months (42% and 41%, respectively). The percentage of children without functional constipation, irrespective of continuation of laxative use, was not statistically different between groups over 8 months (aRR 1.12, 95% CI 0.82-1.34). Notably, parents reported significantly more global symptom improvement after physiotherapy than after conventional treatment (aRR 1.40; 95% CI 1.00-1.73). CONCLUSIONS: We find no evidence to recommend physiotherapy for all children with functional constipation in primary care. TRIAL REGISTRATION: Netherlands Trial Registry: NTR4797.

Explanations for medically unexplained symptoms: a qualitative study on GPs in daily practice consultations.

BACKGROUND: General practice is the centre of care for patients with medically unexplained symptoms (MUS). Providing explanations for MUS, i.e. making sense of symptoms, is considered to be an important part of care for MUS patients. However, little is known how general practitioners (GPs) do this in daily practice. OBJECTIVE: This study aimed to explore how GPs explain MUS to their patients during daily general practice consultations. METHODS: A thematic content analysis was performed of how GPs explained MUS to their patients based on 39 general practice consultations involving patients with MUS. RESULTS: GP provided explanations in nearly all consultations with MUS patients. Seven categories of explanation components emerged from the data: defining symptoms, stating causality, mentioning contributing factors, describing mechanisms, excluding explanations, discussing the severity of symptoms and normalizing symptoms. No pattern of how GPs constructed explanations with the various categories was observed. In general, explanations were communicated as a possibility and in a patient-specific way; however, they were not very detailed. CONCLUSION: Although explanations for MUS are provided in most MUS consultations, there seems room for improving the explanations given in these consultations. Further studies on the effectiveness of explanations and on the interaction between patients and GP in constructing these explanations are required in order to make MUS explanations more suitable in daily primary care practice.

Continuity of care and referral rate: challenges for the future of health care.

BACKGROUND: Continuity of care could reduce health care consumption by patients and reduce the number of referrals to specialist care, but it is unknown if there is a difference in referral rates to specific medical specialties. AIM: We aimed to determine the relationship between continuity of care and both the referral rate (referrals per patient per year) and the medical specialties for which this relationship was strongest. DESIGN AND SETTING: A retrospective cohort study of 19333 patients in primary care in the north of the Netherlands. METHOD: Patients with at least two contacts with a general practitioner (GP) over a 2-year period (2013-2014) were included. The number of contacts with their own or other GPs were calculated, and referral rates were determined. Continuity of care was included as a dichotomous variable (absent or present). RESULTS: The odds of being referred were higher for older patients, females and patients with more practitioner contacts. However, the presence of continuity of care was associated with the highest odds of referral. The referral rate was significantly highest for patients with continuity of care when referred to paediatrics, as well as for patients without continuity of care who were referred to gastroenterology, ophthalmology and psychiatry. CONCLUSION: Increased continuity of care decreases referral to specialist care, most notably for referrals to paediatrics. Despite continued pressures on continuity of care, policy makers should invest in this cornerstone of primary care to temper health care expenditures.

The impact of a mobile application-based treatment for urinary incontinence in adult women: Design of a mixed-methods randomized controlled trial in a primary care setting.

AIMS: We aim to assess whether a purpose-developed mobile application (app) is non-inferior regarding effectiveness and cost-effective when used to treat women with urinary incontinence (UI), as compared to care as usual in Dutch primary care. Additionally, we will explore the expectations and experiences of patients and care providers regarding app usage. METHODS: A mixed-methods study will be performed, combining a pragmatic, randomized-controlled, non-inferiority trial with an extensive process evaluation. Women aged ≥18 years, suffering from UI ≥ 2 times per week and with access to a smartphone or tablet are eligible to participate. The primary outcome will be the change in UI symptom scores at 4 months after randomization, as assessed by the International Consultation on Incontinence Modular Questionnaire UI Short Form. Secondary outcomes will be the change in UI symptom scores at 12 months, as well as the patient-reported global impression of improvement, quality of life, change in sexual functioning, UI episodes per day, and costs at 4 and 12 months. In parallel, we will perform an extensive process evaluation to assess the expectations and experiences of patients and care providers regarding app usage, making use of interviews, focus group sessions, and log data analysis. CONCLUSION: This study will assess both the effectiveness and cost-effectiveness of app-based treatment for UI. The combination with the process evaluation, which will be performed in parallel, should also give valuable insights into the contextual factors that influence the effectiveness of such a treatment.
