Topical or oral antibiotics in childhood acute otitis media and ear discharge: a randomized controlled non-inferiority trial.

BACKGROUND: Current guidance suggests oral antibiotics can be considered for children with acute otitis media (AOM) and ear discharge, but there is an absence of evidence regarding the relative effectiveness of antibiotic-corticosteroid eardrops. AIM: To establish whether antibiotic-corticosteroid eardrops are non-inferior to oral antibiotics in children with AOM and ear discharge. DESIGN AND SETTING: Open randomized controlled non-inferiority trial set in Dutch primary care. METHODS: Children were randomized to hydrocortisone-bacitracin-colistin eardrops (five drops, three times per day in the discharging ear(s)) or amoxicillin suspension (50 mg per kilogram of body weight per day, divided over three doses administered orally) for 7 days. The primary outcome was the proportion of children with resolution of ear pain and fever at day 3. RESULTS: Between December 2017 and March 2023, 58 of the planned 350 children were recruited due to slow accrual for various reasons. Children assigned to eardrops (n = 26) had lower resolution rates of ear pain and fever at 3 days compared to those receiving oral antibiotics (n = 31): 42% vs 65%; adjusted risk difference 20.3%, 95% confidence interval -5.3% to 41.9%), longer parent-reported ear discharge (6 vs 3 days; P = .04), and slightly higher mean ear pain scores (Likert scale 0-6) over days 1-3 (2.1 vs 1.4, P = .02), but received fewer oral antibiotic courses in 3months (11 for 25 children vs 33 for 30 children), and had less GI upset and rash (12% vs 32% and 8% vs 16%, respectively). CONCLUSION: Early termination stopped us from determining non-inferiority of antibiotic-corticosteroid eardrops. Our limited data, requiring confirmation, suggest that oral antibiotics may be more effective than antibiotic-corticosteroid eardrops in resolving symptoms and shortening the duration of ear discharge.

Bacterial agents in vulvovaginitis and vaginal discharge: a 10-year retrospective study in the Netherlands.

Vulvovaginitis is a common problem in the GP's practice. Causes are bacterial vaginosis (BV), Candida infection and sexually transmitted infections (STIs). Only if empirical treatment fails, a vaginal swab is sent in for culture and BV detection. However, without culture essential, bacterial pathogens may escape diagnosis. Many molecular BV assays have recently appeared on the marketplace, all quite differing in price and targets. However, for years, the Nugent score has been the gold standard for BV detection. We analysed retrospectively 10 years of microbiology results of vulvovaginal swabs, focusing on less frequently reported bacterial pathogens, and assessed the characteristics of BV diagnostics. Vulvovaginal swabs sent in between 2010 and 2020 from > 11,000 GP patients with vulvovaginitis associated symptoms, but negative STI tests, were analysed. First cultures and repeat cultures after at least 6 months were included in four age groups: < 12, 12-17, 18-51 and > 51 years. Candida species and BV were most frequently found, with the highest prevalence in premenopausal women. Haemophilus influenzae, beta-haemolytic streptococci, Streptococcus pneumoniae and Staphylococcus aureus were isolated in 5.6% of all cultures, with the highest percentages in children and postmenopausal women. If empirical treatment of vulvovaginitis fails, bacterial culture should be performed to detect all potentially pathogenic microorganisms to obtain a higher rate of successful diagnosis and treatment, avoiding unnecessary antimicrobial use and costs. For BV detection, molecular testing may seem attractive, but Nugent scoring still remains the low-cost gold standard. We recommend incorporating the above in the appropriate guidelines.

Incidence and management of acute otitis media in adults: a primary care-based cohort study.

BACKGROUND: Although primarily considered a childhood disease, acute otitis media (AOM) also occurs in adults. Data on the burden of this condition in adults are, however, scarce. OBJECTIVE: To explore the primary care incidence and current management of AOM in adults. METHODS: All patients aged 15 and older included in the routine health care database of the Julius General Practitioners' Network were followed from 2015 to 2018 (contributing to a total of 1 261 575 person-years). We extracted data on AOM episodes, AOM-related consultations, comorbidities, and antibiotic and analgesic prescriptions. RESULTS: Five thousand three hundred and fifty-eight patients experienced one or more AOM episodes (total number of AOM episodes: 6667; mean 1.2 per patient). The overall AOM incidence was 5.3/1000 person-years and was fairly stable over the study period. Incidence was particularly high in atopic patients (7.3/1000 person-years) and declined with age (from 7.1 in patients 15-39 years of age to 2.7/1000 person-years in those aged 64 years and older). Oral antibiotics, predominantly amoxicillin, were prescribed in 46%, and topical antibiotics in 21% of all episodes. CONCLUSION: Over the past years, the incidence of AOM in adults in primary care has been stable. Oral antibiotic prescription rates resemble those in children with AOM, whereas a remarkably high topical antibiotic prescription rate was observed. Future prognostic research should inform on the need and feasibility of prospective studies into the best management strategy in this condition.

Bidirectional learning opportunities: How GP-supervisors and trainees exchange knowledge.

INTRODUCTION: Workplace-based learning conversations can be a good opportunity for supervisors and trainees to learn from each other. When both professionals discuss their specific knowledge openly with each other, learning conversations may be a useful educational tool, for instance for learning how to apply evidence-based medicine (EBM) in the workplace. We do, however, need a better understanding of how the exchange of knowledge provides opportunities for such bidirectional learning. The aim of this study was therefore to analyse how trainees and supervisors currently handle bidirectional learning opportunities by describing in detail how supervisors respond to knowledge expressed by trainees during a learning conversation. METHOD: We video-recorded learning conversations between supervisors and trainees in general practice (GP). Within these learning conversations, EBM discussions on medical topics were selected and transcribed. We then identified, analysed using Conversation Analysis (CA) and categorised each expression of knowledge by the trainee and the supervisor's subsequent response. RESULTS: We found that when a trainee expresses knowledge during the learning conversation, supervisors either (a) refute the expressed knowledge, (b) immediately suggest an alternative or (c) pose (additional) questions. These responses have consequences for the learning opportunities of both trainee and supervisor: it is only when supervisors pose further questions that trainees are encouraged to elaborate on their knowledge, leading to a bidirectional learning opportunity. DISCUSSION: Improving EBM learning opportunities for both supervisors and trainees requires more than simply instructing trainees to express knowledge-based-for instance-on recent evidence more often. Inflexible institutional roles related to historical claims of supervisors' epistemic authority hamper bidirectional learning. Posing open questions during learning conversations enhances the flexibility of institutional roles while also creating bidirectional learning opportunities.

Cost of childhood acute otitis media in primary care in the Netherlands: economic analysis alongside a cluster randomised controlled trial.

BACKGROUND: Acute otitis media (AOM) is among the most common paediatric conditions managed in primary care. Most recent estimates of the cost of AOM date from a decade ago and lack a full societal perspective. We therefore explored the societal cost of childhood AOM in the Netherlands within the setting of a trial comparing the effectiveness of an intervention aimed at educating general practitioners (GPs) about pain management in AOM compared to usual care. METHODS: Economic analysis alongside a cluster randomised controlled trial conducted between February 2015 and May 2018 in 37 practices (94 GPs). In total, 224 children with AOM were included of which 223 (99%) completed the trial (intervention: n = 94; control: n = 129). The cost of AOM due to health care costs, patient and family costs, and productivity losses by parent caregivers were retrieved from study diaries and primary care electronic health records, during 28-day follow-up. We calculated mean cost (€ and $) per AOM episode per patient with standard deviations (SD, in €) regardless of study group assignment because there was no clinical effect of the trial intervention. In sensitivity analysis, we calculated cost in the intervention and usual care group, after exclusion of extreme outliers. RESULTS: Mean total AOM cost per patient were €565.93 or $638.78 (SD €1071.01); nearly 90% of these costs were due to productivity losses experienced by parents. After exclusion of outliers, AOM cost was €526.70 or $594.50 (SD €987.96) and similar in the intervention and usual care groups: €516.10 or $582.53 (SD €949.69) and €534.55 or $603.36 (SD €920.55) respectively. CONCLUSIONS: At €566 or $639 per episode, societal cost of AOM is higher than previously known and mainly driven by productivity losses by children's parents. Considering its high incidence, AOM poses a significant economic burden that extends beyond direct medical costs. TRIAL REGISTRATION: Netherlands Trial Register no.

Learning Conversations with Trainees: An Undervalued but Useful EBM Learning Opportunity for Clinical Supervisors.

Phenomenon: Supervisors and trainees can learn skills related to evidence-based medicine from each other in the workplace by collaborating and interacting, in this way benefiting from each other's strengths. This study explores supervisors' perceptions of how they currently learn evidence-based medicine by engaging in learning conversations with their trainee. Approach: Semi-structured, video-stimulated elicitation interviews were held with twenty-two Dutch and Belgian supervisors in general practice. Supervisors were shown fragments of their video-recorded learning conversations, allowing them to reflect. Recorded interviews were analyzed using a grounded theory-based approach.Findings: Supervisors did not immediately perceive workplace learning conversations as an opportunity to learn evidence-based medicine from their trainee. They mostly saw these conversations as a learning opportunity for trainees and a chance to maintain the quality of care within their practice. Nevertheless, during the interviews, supervisors did acknowledge that learning conversations help them to gain up-to-date knowledge and search skills or more awareness of their own knowledge or gaps in their knowledge. Not identified as a learning outcome was how to apply evidence-based medicine within a clinical practice by combining evidence with clinical expertise and the patient's preferences. Insights: Supervisors acknowledge that they learn elements of the three aspects of evidence-based medicine by having learning conversations with their trainee, but they currently see this as secondary to the trainee's learning process. Emphasizing opportunities for bidirectional learning could improve learning of evidence-based medicine during workplace learning conversations.

Transcending boundaries for collaborative patient care.

Dutch general practitioners (GPs) and medical specialists (MSs) create collaborative patient care agreements (CPCAs) to improve intraprofessional collaboration. We set out to identify contradictions between the activity systems of primary and secondary care that could result in expansive learning and new ways of working collaboratively. We analysed nineteen semi-structured interviews using activity theory (AT) as a theoretical framework and using these two activity systems as the units of analysis. There were contradictions within and between the activity systems related, for example, to different understandings of 'care' in generalist and specialist settings. GPs and MSs were able to identify contradictions and learn expansively when they iteratively co-created CPCAs in groups. They found it much harder to tackle contradictions, however, when they disseminated these tools within their respective professional communities, leaving unresolved contradictions and missed opportunities for collaboration. This research shows the educational benefits of taking collective responsibility for improving collaborative patient care.

Supervisors' pedagogies for supporting interns to learn intra- and interprofessional collaboration: a qualitative and quantitative ego network analysis.

This work aims to understand intra- and interprofessional networks of general practitioners (GPs) and ear, nose, and throat specialists (ENT specialists), and in what manner supervisors in these specialties involve interns in their professional network to help them learn intra- and interprofessional collaboration. An egocentric social network approach was used to collect and analyze quantitative as well as qualitative data. For this, semi-structured interviews were held with ten GP and ten ENT specialists. GPs had significantly more interprofessional contacts than ENT specialists (p < .01), with no significant difference in the network sizes of both professions (p = .37). All supervisors involved interns in their (ego)network actively as well as more passively. They actively discussed how collaboration with other professionals evolved, or passively assumed that an intern would learn from observing the supervisors' network interactions. Many supervisors considered the interns' initiative essential in deciding to involve an intern in their network. Although the workplace of GPs differed notably from hospital settings where ENT specialists work, the network sizes of both were comparable. Clerkships at the general practice seemed to provide more opportunities to learn interprofessional collaboration, for example with the medical nurse. Supervisors in both specialties could involve interns more actively in their intra- and interprofessional network while interns could take more initiative to learn collaboration from their supervisors' network.

Applying evidence-based medicine in general practice: a video-stimulated interview study on workplace-based observation.

BACKGROUND: Evidence-based medicine (EBM) in general practice involves applying a complex combination of best-available evidence, the patient's preferences and the general practitioner's (GP) clinical expertise in decision-making. GPs and GP trainees learn how to apply EBM informally by observing each other's consultations, as well as through more deliberative forms of workplace-based learning. This study aims to gain insight into workplace-based EBM learning by investigating the extent to which GP supervisors and trainees recognise each other's EBM behaviour through observation, and by identifying aspects that influence their recognition. METHODS: We conducted a qualitative multicentre study based on video-stimulated recall interviews (VSI) of paired GP supervisors and GP trainees affiliated with GP training institutes in Belgium and the Netherlands. The GP pairs (n = 22) were shown fragments of their own and their partner's consultations and were asked to elucidate their own EBM considerations and the ones they recognised in their partner's actions. The interview recordings were transcribed verbatim and analysed with NVivo. By comparing pairs who recognised each other's considerations well with those who did not, we developed a model describing the aspects that influence the observer's recognition of an actor's EBM behaviour. RESULTS: Overall, there was moderate similarity between an actor's EBM behaviour and the observer's recognition of it. Aspects that negatively influence recognition are often observer-related. Observers tend to be judgemental, give unsolicited comments on how they would act themselves and are more concerned with the trainee-supervisor relationship than objective observation. There was less recognition when actors used implicit reasoning, such as mindlines (internalised, collectively reinforced tacit guidelines). Pair-related aspects also played a role: previous discussion of a specific topic or EBM decision-making generally enhanced recognition. Consultation-specific aspects played only a marginal role. CONCLUSIONS: GP trainees and supervisors do not fully recognise EBM behaviour through observing each other's consultations. To improve recognition of EBM behaviour and thus benefit from informal observational learning, observers need to be aware of automatic judgements that they make. Creating explicit learning moments in which EBM decision-making is discussed, can improve shared knowledge and can also be useful to unveil tacit knowledge derived from mindlines.

GP trainees' perceptions on learning EBM using conversations in the workplace: a video-stimulated interview study.

BACKGROUND: To be able to practice evidence-based medicine (EBM) when making decisions for individual patients, it is important to learn how to combine the best available evidence with the patient's preferences and the physician's clinical expertise. In general practice training, these skills can be learned at the workplace using learning conversations: meetings between the supervising general practitioner (GP) and GP trainee to discuss medical practice, selected topics or professional performance. This study aimed to give insight into the perceptions of GP trainees on their EBM learning processes during learning conversations. METHODS: We held semi-structured video-stimulated elicitation interviews (n = 22) with GP trainees affiliated to GP training institutes in the Netherlands and Belgium. GP trainees were shown fragments of their learning conversations, enabling reflection during the interview. Taking an inductive approach, interview recordings were transcribed verbatim and analysed with NVivo software. RESULTS: GP trainees perceived learning conversations as useful for learning and discussing EBM. Multiple EBM learning activities were identified, such as discussing evidence together, relating evidence to cases in daily practice and discussing the supervisor's experience and the specific local context in the light of what the evidence recommends. However, for learning to occur, trainees need and expect specific behaviour, both from their supervisors and themselves. Supervisors should supply well-substantiated answers that are applicable in practice and give the trainee confirmation. In turn, the trainee needs to prepare well in order to ask focused, in-depth questions. A safe space allowing equal and open discussion between trainee and supervisor is perceived as an essential context for optimal EBM learning. CONCLUSIONS: Our findings show that trainees find learning conversations useful for EBM learning in general practice. To bring EBM learning to its full potential, attention should be paid to optimising the behavioural and contextual factors found relevant to enhancing EBM learning.

Impact of Repeated Influenza Immunization on Respiratory Illness in Children With Preexisting Medical Conditions.

PURPOSE: Annual influenza immunization in medical risk groups is recommended in many countries. Recent evidence suggests that repeated inactivated influenza vaccine (IIV) immunization throughout childhood may impair long-term immunity against influenza. We assessed whether prior immunization altered the effect of IIV in children with preexisting medical conditions on primary care-diagnosed respiratory illness (RI) episodes during the influenza season. METHODS: Electronic records of IIV-immunized children who met the criteria for annual IIV immunization according to Dutch guidelines were extracted from a primary care database from 2004 to 2015. For each year, we collected information on IIV immunization status, primary care-attended RI episodes (including influenza-like illness, acute RI, and asthma exacerbation), and potential confounders. Generalized estimating equations were used to model the association between prior IIV and occurrence of at least one RI episode during the influenza season, with "current year immunized but without IIV history" as reference group. RESULTS: A total of 4,183 children (follow-up duration: 11,493 child-years) were IIV immunized at least once. Adjusted estimates showed lower odds for RI in current year-immunized children with prior IIV compared with those without (odds ratio [OR] = 0.61; 95% CI, 0.47-0.78 for "current year immunized and one IIV in previous 2 years"; OR = 0.85; 95% CI, 0.68-1.07 for "current year immunized and ≥2 IIVs in previous 3 years, including prior year"). CONCLUSION: Repeated IIV immunization in children with preexisting medical conditions has no negative impact on, and may even increase, long-term protection against RI episodes diagnosed during the influenza season in primary care.

Pain management in acute otitis media: a qualitative study of parents' views and expectations.

BACKGROUND: For unclarified reasons, parents tend to be cautious about administering analgesics to their children, potentially leading to suboptimal management of AOM symptoms. We aim to understand parents' views and expectations of pain management in acute otitis media (AOM) in children. METHODS: Qualitative study alongside a cluster-randomised controlled trial (PIM-POM study) aimed at optimising pain management in childhood AOM. We purposefully sampled 14 parents of children diagnosed with AOM by their GP, who were recruited to the trial between November 2017 and May 2018. Semi-structured interviews were held at home in the first two weeks after trial enrollment. Interviews were audio-recorded, transcribed and analyzed thematically. RESULTS: Parents experienced difficulties in recognising earache and other symptoms of an ear infection. They consulted the GP for a diagnosis, for reassurance and for management advice. Parents shared that, prior to consultation, they had insufficient knowledge of the benefits of correctly dosed pain medication at regularly scheduled intervals. Parents valued the GP's advice on pain management, and were happy to accept pain medication as standalone therapy, provided that the GP explained why antibiotics would not be needed. Parents' views and expectations of pain management in AOM were shaped by previous experiences of AOM within their family; those with a positive experience of pain medication are more likely to use it in subsequent AOM episodes. CONCLUSIONS: Parents of children with AOM consult the GP to help cope with uncertainties in recognising symptoms of AOM, and to receive management advice. It is important that GPs are aware of parents' lack of understanding of the role of pain medication in managing AOM, and that they address this during the consultation.

A case study of nurse practitioner care compared with general practitioner care for children with respiratory tract infections.

AIM: To compare quality of care provided by nurse practitioners (NP) with care provided by general practitioners (GP) for children with respiratory tract infections (RTI) in the Netherlands. BACKGROUND: Nurse practitioners increasingly manage acute conditions in general practice, with opportunities for more protocolled care. Studies on quality of NPs' care for children with RTIs are limited to the US healthcare system and do not take into account baseline differences in illness severity. DESIGN: Retrospective observational cohort study. METHODS: Data were extracted from electronic healthcare records of children 0-6 years presenting with RTI between January-December 2013. Primary outcomes were antibiotic prescriptions and early return visits. Generalized estimating equations were used to correct for potential confounders. RESULTS: A total of 899 RTI consultations were assessed (168 seen by NP; 731 by GP). Baseline characteristics differed between these groups. Overall antibiotic prescription and early return visit rates were 21% and 24%, respectively. Adjusted odds ratio for antibiotic prescription after NP vs. GP delivered care was 1.40 (95% confidence interval 0.89-2.22) and for early return visits 1.53 (95% confidence interval 1.01-2.31). Important confounder for antibiotic prescription was illness severity. Presence of wheezing was a confounder for return visits. Complication and referral rates did not differ. CONCLUSION: Antibiotic prescription, complication and referral rates for paediatric RTI consultations did not differ significantly between NP and GP consultations, after correction for potential confounders. General practitioners, however, see more severely ill children and have a lower return visit rate. A randomised controlled study is needed to determine whether NP care quality is truly noninferior.

The use of evidence during group meetings of Dutch general practitioners.

BACKGROUND AND OBJECTIVES: For Evidence Based Medicine (EBM) learning journal clubs are recommended, but these are not common practice. How participants discuss and learn about applying evidence in other group meetings is unknown. We examined different types of group meetings and explored the use of, and discussions about, clinical research evidence. METHODS: A mixed-methods study design was adopted. After distribution and analysis of a questionnaire about types of group meetings, interviews were conducted to better understand the most frequently occurring type. RESULTS: GPs have different types of meetings, but the most common group meetings where evidence wass discussed were so called quality circles, i.e. pharmacotherapy audit meetings in which GPs discuss drug prescription figures or preferred treatment together with pharmacists. Interviews showed that the source of evidence used mostly are the recommendations in the national GP guidelines. The underlying evidence or new research did not play an important role in the discussions. CONCLUSIONS: Quality circles seem to be more goal-oriented than learning oriented. Learning discussions about controversies in clinical research or about the integration of evidence, patient values and clinical expertise occurred infrequently. To harvest the potential value of group meetings for EBM learning, quality circles in their present design are not optimal.

Intraprofessional collaboration and learning between specialists and general practitioners during postgraduate training: a qualitative study.

BACKGROUND: During postgraduate training, general practitioners and other specialists must learn how to deliver shared care to patients; however, the development of formal intraprofessional education is often hampered by curricular constraints. Delivering shared care in everyday work provides trainees with opportunities for informal learning from, about and with one another. METHODS: Twelve semi-structured interviews were undertaken with trainee general practitioners and specialists (internal medicine or surgery). A thematic analysis of the input was undertaken and a qualitative description developed. RESULTS: Trainees from different disciplines frequently interact, often by telephone, but generally they learn in a reactive manner. All trainees are highly motivated by the desire to provide good patient care. Specialist trainees learn about the importance of understanding the background of the patient from GPs, while GP trainees gain medical knowledge from the interaction. Trainees from different disciplines are not very motivated to build relationships with each other and have fewer opportunities to do so. Supervisors can play an important role in providing intraprofessional learning opportunities for trainees. CONCLUSIONS: During postgraduate training, opportunities for intraprofessional learning occur, but there is much room for improvement. For example, supervisors could increase the involvement of trainees in collaborative tasks and create more awareness of informal learning opportunities. This could assist trainees to learn collaborative skills that will enhance patient care.

Pneumococcal conjugate vaccines for preventing otitis media.

BACKGROUND: Acute otitis media (AOM) is a very common respiratory infection in early infancy and childhood. The marginal benefits of antibiotics for AOM in low-risk populations in general, the increasing problem of bacterial resistance to antibiotics and the huge estimated direct and indirect annual costs associated with otitis media (OM) have prompted a search for effective vaccines to prevent AOM. OBJECTIVES: To assess the effect of pneumococcal conjugate vaccines (PCVs) in preventing AOM in children up to 12 years of age. SEARCH METHODS: We searched CENTRAL (2013, Issue 11), MEDLINE (1995 to November week 3, 2013), EMBASE (1995 to December 2013), CINAHL (2007 to December 2013), LILACS (2007 to December 2013) and Web of Science (2007 to December 2013). SELECTION CRITERIA: Randomised controlled trials (RCTs) of PCVs to prevent AOM in children aged 12 years or younger, with a follow-up of at least six months after vaccination. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality and extracted data. MAIN RESULTS: We included 11 publications of nine RCTs (n = 48,426 children, range 74 to 37,868 per study) of 7- to 11-valent PCV (with different carrier proteins). Five trials (n = 47,108) included infants, while four trials (n = 1318) included children aged one to seven years that were either healthy (one study, n = 264) or had a previous history of upper respiratory tract infection (URTI), including AOM. We judged the methodological quality of the included studies to be moderate to high. There was considerable clinical diversity between studies in terms of study population, type of conjugate vaccine and outcome measures. We therefore refrained from pooling the results.In three studies, the 7-valent PCV with CRM197 as carrier protein (CRM197-PCV7) administered during early infancy was associated with a relative risk reduction (RRR) of all-cause AOM ranging from -5% in high-risk children (95% confidence interval (CI) -25% to 12%) to 7% in low-risk children (95% CI 4% to 9%). Another 7-valent PCV with the outer membrane protein complex of Neisseria meningitidis (N. meningitidis) serogroup B as carrier protein, administered in infancy, did not reduce overall AOM episodes, while a precursor 11-valent PCV with Haemophilus influenzae (H. influenzae) protein D as carrier protein was associated with a RRR of all-cause AOM episodes of 34% (95% CI 21% to 44%).A 9-valent PCV (with CRM197 carrier protein) administered in healthy toddlers was associated with a RRR of (parent-reported) OM episodes of 17% (95% CI -2% to 33%). CRM197-PCV7 followed by 23-valent pneumococcal polysaccharide vaccination administered after infancy in older children with a history of AOM showed no beneficial effect on first occurrence and later AOM episodes. In a study in older children with a previously diagnosed respiratory tract infection, performed during the influenza season, a trivalent influenza vaccine combined with placebo (TIV/placebo) led to fewer all-cause AOM episodes than vaccination with TIV and PCV7 (TIV/PCV7) when compared to hepatitis B vaccination and placebo (HBV/placebo) (RRR 71%, 95% CI 30% to 88% versus RRR 57%, 95% CI 6% to 80%, respectively) indicating that CRM197-PCV7 after infancy may even have negative effects on AOM. AUTHORS' CONCLUSIONS: Based on current evidence of the effects of PCVs for preventing AOM, the licensed 7-valent CRM197-PCV7 has modest beneficial effects in healthy infants with a low baseline risk of AOM. Administering PCV7 in high-risk infants, after early infancy and in older children with a history of AOM, appears to have no benefit in preventing further episodes. Currently, several RCTs with different (newly licensed, multivalent) PCVs administered during early infancy are ongoing to establish their effects on AOM. Results of these studies may provide a better understanding of the role of the newly licensed, multivalent PCVs in preventing AOM. Also the impact on AOM of the carrier protein D, as used in certain pneumococcal vaccines, needs to be further established.

Dutch postgraduate GP selection procedure; reliability of interview assessments.

BACKGROUND: Semi- structured interviews are the core of the Dutch selection procedure for postgraduate general practice (GP) training. A staff member, trainer and trainee independently assess personal qualities. Aiming to improve the selection procedure we were interested in the reliability aspects of these interviews. We investigated the inter-rater reliability of the interview for groups of two or three assessors and the degree to which candidates' characteristics and qualities assessed during interviews explained admission into GP training, controlled for differences between those who apply for the first versus the second or third application. METHODS: An observational study was conducted of all candidates who entered the Utrecht selection procedure between April 2008 and 2010. Candidates' characteristics and qualities were collected. Inter-rater reliability of different compositions of the interview group per quality was estimated. Factors associated with admission into GP training were assessed. RESULTS: The study population included 394 candidates. Twenty-six candidates were rejected based on their application letter (4.4%). Three candidates who applied more than 3 times were excluded. Ultimately, 206 of the 365 candidates were admitted to the GP training (56,4%). The inter-rater reliability was satisfactory (ICC: 0.78 - 0 .84). Reduction from three to two assessors slightly reduces the ICC. The candidates' qualities independently explained admission to GP training, whereas individual characteristics did not. These results did not differ for candidates who applied for the first time versus candidates applying for the second or third time. CONCLUSION: Selection interviews with two assessors yielded a satisfactory level of reliability. Individual characteristics were not associated with admission, whereas scores related to candidate qualities did show such an association. The results of those applying for the second or third time were similar.

[Blueprint of the 2035 specialty landscape in the Netherlands]. / Op naar een nieuw specialismenlandschap.

The Medical Specialties council of the Royal Dutch medical association (CGS) has published an innovative perspective on the future landscape of specialisms in medicine. The proposal introduces generalism as the standard of training and professional practice, which represents a fundamental change from the current system. The envisioned new structure would consist of a number of broad core specialisms, emphasizing generalist knowledge and skills, and additional subspecialties for highly complex care. This is expected to enhance healthcare efficiency and improve patient treatment. The plan meets changing healthcare needs and accommodates the preference of young doctors regarding their residency training and careers.The CGS wants to further explore the new perspective with all parties involved.

Effectiveness of analgesic ear drops as add-on treatment to oral analgesics in children with acute otitis media: study protocol of the OPTIMA pragmatic randomised controlled trial.

INTRODUCTION: Ear pain is the most prominent symptom of childhood acute otitis media (AOM). To control the pain and reduce reliance on antibiotics, evidence of effectiveness for alternative interventions is urgently needed. This trial aims to investigate whether analgesic ear drops added to usual care provide superior ear pain relief over usual care alone in children presenting to primary care with AOM. METHODS AND ANALYSIS: This is a pragmatic, two-arm, individually randomised, open, superiority trial with cost-effectiveness analysis and nested mixed-methods process evaluation in general practices in the Netherlands. We aim to recruit 300 children aged 1-6 years with a general practitioner (GP) diagnosis of AOM and ear pain. Children will be randomly allocated (ratio 1:1) to either (1) lidocaine hydrochloride 5 mg/g ear drops (Otalgan) one to two drops up to six times daily for a maximum of 7 days in addition to usual care (oral analgesics, with/without antibiotics); or (2) usual care. Parents will complete a symptom diary for 4 weeks as well as generic and disease-specific quality of life questionnaires at baseline and 4 weeks. The primary outcome is the parent-reported ear pain score (0-10) over the first 3 days. Secondary outcomes include proportion of children consuming antibiotics, oral analgesic use and overall symptom burden in the first 7 days; number of days with ear pain, number of GP reconsultations and subsequent antibiotic prescribing, adverse events, complications of AOM and cost-effectiveness during 4-week follow-up; generic and disease-specific quality of life at 4 weeks; parents' and GPs' views and experiences with treatment acceptability, usability and satisfaction. ETHICS AND DISSEMINATION: The Medical Research Ethics Committee Utrecht, the Netherlands, has approved the protocol (21-447/G-D). All parents/guardians of participants will provide written informed consent. Study results will be submitted for publication in peer-reviewed medical journals and presented at relevant (inter)national scientific meetings. TRIAL REGISTRATION: The Netherlands Trial Register: NL9500; date of registration: 28 May 2021. At the time of publication of the study protocol paper, we were unable to make any amendments to the trial registration record in the Netherlands Trial Register. The addition of a data sharing plan was required to adhere to the International Committee of Medical Journal Editors guidelines. The trial was therefore reregistered in ClinicalTrials.gov (NCT05651633; date of registration: 15 December 2022). This second registration is for modification purposes only and the Netherlands Trial Register record (NL9500) should be regarded as the primary trial registration.
