[Reliable diagnostics: clinical gestalt or prediction rule?] / Klinische blik of beslisregel.

Diagnostic prediction models can support the diagnostic process, both for experienced physicians and for physicians with little experience. More attention should be paid to the incorporation of diagnostic prediction models in the electronic patient record, so that a more accurate probability estimate can be made without simplification to rounded sumscores. A uniform cut-off of sum scores with associated categorization is also undesirable, because it does not take the context of the individual patient sufficiently into account. In the case of a very strong gut feeling, the outcome of a diagnostic prediction model rule alone cannot be sufficient for further policy. Diagnostic prediction models 'only' generate individual objectively estimated probabilities; the clinical decision-making based on these probabilities always needs to be made by the doctor in shared decision making with the patient. Conflict of interest and financial support: none declared.

[Intensive covid-19 care in general practice; nationwide registration study, initiated by General Practice Research Consortium Netherlands]. / Intensieve en palliatieve covid-19-zorg door huisarts.

METHOD: Registration system initiated by General Practice Research Consortium Netherlands (GPRC-NL). AIM: To obtain national estimates on clinically suspected Covid-19 mortality in general practice and on intensive and palliative covid-19 care provided by general practitioners (GPs) outside hospital, including palliative medication, availability of personal protective equipment, and reasons for not referring to hospital of vulnerable patients during the first three months of the Covid-19 pandemic in The Netherlands. DESIGN: Nationwide registration study, in which 2.331 GP practices in The Netherlands participated from March-June 2020. METHOD: Registration system initiated by General Practice Research Consortium Netherlands (GPRC-NL) through existing digital referral platform ZorgDomein, in which GPs could report PCR-proven and clinically suspected Covid-19 deceased patients to estimate the impact of the Covid-19 pandemic in primary care. RESULTS: GPs reported 1,566 Covid-19 deceased patients, of which 61% (949/1,566) were clinically suspected but not PCR-tested, with large regional differences, and most deaths being reported in the provinces of Brabant and Limburg. Patients had a median duration from onset of symptoms to death of 8 days and a median age of 87 years. GPs reported 1,030 patients for which they delivered intensive or palliative care, of which 56% had a Clinical Frailty Score higher or equal to six. Most mentioned reason for GPs and patients in the decision not going to hospital were the explicit wish of the patient (59%) and somatic vulnerability (52%). CONCLUSION: GPs provided palliative care to a large number of clinically suspected Covid-19 vulnerable patients with large regional differences across The Netherlands. Reported GPs' and patients' considerations to refrain from hospital care can be used to guide future primary care for vulnerable Covid-19 patients.

[Flash mob studies; science in a flash]. / Flashmobstudies: wetenschap in een flits.

The flash mob method is a new way of conducting prospective research whereby relatively simple - but clinically relevant - questions can be answered in a short period of time. The design and intensity of the spirited action - the 'flash' - with which the research is initiated determines the size of the group - the 'mob' - of researchers who will collect research data, and therefore determine the size of the study population. The reach of a flash mob study differs from that of traditional studies and gives flash mob studies a special character. In this article we show how the flash mob method works, the opportunities that it presents, its limitations and the kinds of questions it is able to answer.

[COVID-19: care at home or in hospital? Considerations in primary care]. / COVID-19: thuis behandelen of naar het ziekenhuis?

COVID-19 is a treacherous disease, in which infected patients who appear to fare well can deteriorate rapidly, mostly due to respiratory failure. For general practitioners (and other first-line responders), a clinical evaluation at any given time merely provides a snapshot of the patient's condition. Therefore, frequent monitoring is warranted in at-risk patients. However, there is no one-size-fits-all approach for monitoring, treatment and referral decisions. This is particularly the case in patients with advanced age. In this article, through the use of case examples, we aim to provide guidance when facing difficult management decisions in patients with (suspected) COVID-19.

Burden of disease in children with respiratory tract infections in primary care: diary-based cohort study.

BACKGROUND: Respiratory tract infections (RTIs) are a common reason for children to consult in general practice. Antibiotics are often prescribed, in part due to miscommunication between parents and GPs. The duration of specific respiratory symptoms has been widely studied. Less is known about illness-related symptoms and the impact of these symptoms on family life, including parental production loss. Better understanding of the natural course of illness-related symptoms in RTI in children and impact on family life may improve GP-parent communication during RTI consultations. OBJECTIVE: To describe the general impact of RTI on children and parents regarding illness-related symptoms, absenteeism from childcare, school and work, use of health care facilities, and the use of over-the-counter (OTC) medication. METHODS: Prospectively collected diary data from two randomized clinical trials in children with RTI in primary care (n = 149). Duration of symptoms was analysed using survival analysis. RESULTS: Disturbed sleep, decreased intake of food and/or fluid, feeling ill and/or disturbance at play or other daily activities are very common during RTI episodes, with disturbed sleep lasting longest. Fifty-two percent of the children were absent for one or more days from childcare or school, and 28% of mothers and 20% of fathers reported absence from work the first week after GP consultation. Re-consultation occurred in 48% of the children. OTC medication was given frequently, particularly paracetamol and nasal sprays. CONCLUSION: Appreciation of, and communication about the general burden of disease on children and their parents, may improve understanding between GPs and parents consulting with their child.

Optimizing decision-making among childcare staff on fever and common infections: cluster randomized controlled trial.

BACKGROUND: Children 0-4 years attending childcare are more prone to acquire infections than home-cared children. Childcare illness absenteeism due to fever is mostly driven by fear towards fever in childcare staff and parents. This may cause high childcare absenteeism, healthcare service use, and work absenteeism in parents. This study evaluates a multicomponent intervention targeting determinants of decision-making among childcare staff on illness absenteeism due to fever and common infections. METHODS: The multicomponent intervention was developed based on the Intervention Mapping approach and consisted of (i) an educational session, (ii) a decision tool, (iii) an information booklet and (iv) an online video. The intervention was evaluated in a cluster randomized controlled trial in Southern Netherlands. Nine centres received the intervention and nine provided childcare-as-usual. Primary outcome measure was the percentage of illness absenteeism on cluster level, defined as number of childcare days absent due to illness on total of registered childcare contract days in a 12-week period. Secondary outcome measures included intended behaviour, attitude, risk perception, knowledge and self-efficacy of childcare staff. Outcomes were analyzed using linear mixed models accounting for clustering. Knowledge was descriptively analysed. RESULTS: Overall illness absenteeism was comparable in intervention (2.95%) and control group (2.52%). Secondary outcomes showed significant improvements in intervention group regarding intended behaviour, two of three attitude dimensions. Knowledge increased compared with control but no differences regarding self-efficacy. CONCLUSION: The intervention was not effective in reducing illness absenteeism. However, the intervention improved determinants of decision-making such as intended behaviour, attitude, and knowledge on fever. TRIAL REGISTRATION: NTR6402 (registered on 21 April 2017).

Optimising decision making on illness absenteeism due to fever and common infections within childcare centres: development of a multicomponent intervention and study protocol of a cluster randomised controlled trial.

BACKGROUND: Evidence has shown that children 0-4 year-old attending childcare are prone to acquire infections compared to children cared for at home, with fever being the most common symptom. Illness absenteeism due to fever and common infections is substantial and mostly driven by unrealistic concerns and negative attitude towards fever of both childcare staff and parents, resulting in illness absenteeism from childcare, work absenteeism among parents and healthcare service use. The objective of this study is to optimise decision making among childcare staff on illness absenteeism due to fever and common infections in childcare. Underlying determinants of behavioural change were targeted by means of a multicomponent intervention. METHODS: A multicomponent intervention was developed to improve decision making, using the stepwise approach of Intervention Mapping, and in close collaboration with stakeholders and experts. The intervention consisted of 1) a two-hour educational session on fever among childcare staff; 2) an online video for childcare staff and parents emphasising key information of the educational session; 3) a decision tool for childcare staff and parents in the format of a traffic light system to estimate the severity of illness and corresponding advices for childcare staff and parents; 4) an information booklet regarding childhood fever, common infections, and self-management strategies for childcare staff and parents. The multicomponent intervention will be evaluated in a cluster randomised trial with a 12-week follow-up period and absenteeism due to illness (defined as the percentage of childcare days absent due to illness on the total of childcare days during a 12-week period) as primary outcome measure. Secondary outcome measures are: incidence rate and duration of illness episodes, knowledge, attitude, self-efficacy, and risk perception on fever and common infections of childcare staff and parents, healthcare service use in general and paracetamol use, and work absenteeism of parents. DISCUSSION: This study aims to develop a multicomponent intervention and to evaluate to what extent illness absenteeism due to fever and common infections can be affected by implementing a multicomponent intervention addressing decision making and underlying determinants among childcare staff and parents of children attending daycare. TRIAL REGISTRATION: NTR6402 (registered on 21-apr-2017).

[Amoxicillin and paracetamol dosing in children: playing safe]. / Amoxicilline en paracetamol doseren bij kinderen.

Amoxicillin and paracetamol are the two most widely prescribed and recommended medicines in children. Due to lack of scientific evidence of the most effective dosage, dosing instructions of both medicines are often unclear. In this article we challenge general practitioners, paediatricians, child-health clinic physicians, ENT specialists, pharmacists and guideline committees to critically evaluate the current dosing instructions of these two medicines. The Netherlands paediatric formulary, the Kinderformularium, should become the primary formulary for children in the Netherlands, but it has to be more in line with daily practice, and basic dosing instructions should be less ambiguous: (a) dosing instructions based on body weight instead of age; b) in case of pain, paracetamol should be given 60 mg/kg/day in four divided doses; (c) in case of common uncomplicated infections, amoxicillin should be given orally 60 mg/kg/day in two divided doses; (d) the following should be mentioned on the antibiotic prescription: the daily dose, the number of divided doses, the duration of therapy, the indication for the prescription, and the child's weight. This will result in safe prescription of medicines for children, with fewer unnecessary disruptive consultations between prescriber and pharmacist.

Who tests whom? A comprehensive overview of Chlamydia trachomatis test practices in a Dutch region among different STI care providers for urogenital, anorectal and oropharyngeal sites in young people: a cross-sectional study.

OBJECTIVES: To evaluate and compare Chlamydia trachomatis (CT) diagnostic test practices of different sexually transmitted infection (STI) care providers in 16-29 year olds from one defined geographic Dutch region (280,000 inhabitants). Both number and proportion of positive CT tests (ie, test positivity) were assessed, and factors associated with these outcomes. METHODS: Data on laboratory testing and diagnosis of urogenital, anorectal and oropharyngeal CT between 2006 and 2010 were retrieved from general practitioners (GPs), gynaecologists, an STI clinic and a population-based chlamydia screening programme. Multivariable regression analyses explored associations between age, sex, test year, socio-economic status (SES) and STI care provider and the outcomes being the number of tests and test positivity. RESULTS: Overall, 22,831 tests were performed (1868 positive; 8.2%). Extragenital (ie, anorectal and oropharyngeal) tests accounted for 4% of all tests (7.5% positive) and were almost exclusively (99%) performed by the STI clinic. STI clinics tested most men (37.2% of all tested men), whereas GPs tested most women (29.9% of all tested women). GPs and STI clinics accounted for 73.3% (1326/1808) of urogenital CT diagnoses. In women, the number of tests increased with age, whereas test positivity decreased for all STI care providers. Lower SES was associated with higher test positivity in GP and gynaecology patients. CONCLUSIONS: STI clinics performed most CT tests in men, whereas GPs performed most CT tests in women. GPs and STI clinics accounted for the majority of positives. Extragenital CT testing is rarely performed outside the STI clinic and needs to be promoted, especially in men who have sex with men.

[The practice guideline 'Influenza and influenza vaccination' (first revision) from the Dutch College of General Practitioners; a response from the perspective of general practice]. / De standaard 'Influenza en influenzavaccinatie' (eerste herziening) van het Nederlands Huisartsen Genootschap; reactie vanuit de huisartsgeneeskunde.

The first revision of the guideline 'Influenza and influenza vaccination' from the Dutch College of General Practitioners illustrates that influenza has evolved from a supposedly harmless condition to a disease against which growing numbers of patients and healthcare professionals are vaccinated. Although recent studies support its effectiveness, it is still believed that vaccination may prevent serious health problems in the vulnerable patients, notably in homes for the elderly and nursing homes. In order to streamline diagnostic triage in cases of flu-like symptoms, general practitioners must keep abreast of the actual influenza figures, but also be aware that not all patients with flu-like symptoms have influenza. Pneumonia should always be present in the differential diagnosis of influenza.
