Diagnostic Accuracy of Blind Bronchial Sample Testing by BioFire Pneumonia plus Panel in Pediatric Intensive Care Unit Patients and Its Impact in Early Adaptation of Antimicrobial Therapy: A Prospective Observational Study

BACKGROUND

Community-acquired and nosocomial lower-respiratory-tract infections in critically ill pediatric patients require early appropriate antibiotic therapy to optimize outcomes. Using blind bronchial samples, we assessed the diagnostic performance of the rapid-multiplex polymerase chain reaction (PCR) assay BioFire Pneumonia plus Panel vs. reference standard culturing with antimicrobial susceptibility testing.

METHODS

For this prospective observational study in a single pediatric intensive care unit, we included consecutive patients younger than 18 years admitted for suspected community-, hospital- or ventilator-associated pneumonia in 2021-2022. Sensitivity, specificity, positive predictive value and negative predictive value of the multiplex PCR assay were determined. The kappa coefficient was computed to assess agreement, and univariate analyses were done to identify factors associated with discrepancies between the 2 diagnostic methods.

RESULTS

Of the 36 included patients (median age, 1.4 years; interquartile range, 0.2-9.2), 41.7%, 27.8%, and 30.5% had community-, hospital- and ventilator-associated pneumonia, respectively. The overall κ was 0.74, indicating good agreement. Overall, the sensitivity of the multiplex PCR assay was 92% (95% CI: 77%-98%) and specificity 95% (95% CI: 92%-97%), with variations across microorganisms. The median time from sample collection to antimicrobial susceptibility test results was 3.9 (2.5-15) hours with the multiplex PCR assay and 60.5 (47.6-72.2) hours with the reference technique.

CONCLUSION

The BioFire Pneumonia plus Panel used to test blind bronchial samples had satisfactory diagnostic performance in critically ill pediatric patients. The rapid results provided by this test may improve the appropriateness of antimicrobial therapy and help minimize the use of antibiotics.

Spouses of patients treated for colon cancer: identification of key caregiver skills using the Delphi method

PURPOSE

Spouses are often the front-line caregivers for colon cancer patients. Providing this support requires a particular set of coping skills. Our objective was to identify key skills that healthcare and medico-social sector professionals could assess in routine practice that would allow them to propose appropriate support to spouses who are accompanying colon cancer patients in their care pathway.

METHODS

An online two-round Delphi study was conducted among French colon cancer patients, spouses and professionals. The content of the Delphi study was developed from a previously published qualitative study.

RESULTS

In the first round of the study, 63% of the participants were professionals (n = 40), 19% spouses (n = 12) and 17% patients (n = 11). In the second round, they were respectively 55% (n = 22), 22% (n = 9) and 22% (n = 9). Twenty-seven of the 75 proposed skills were consensually identified as key skills. Nine were related to emotional and psychological well-being, six to social relations, four to organisation, five to health and three to domestic domains. The three most consensual skills (≥ 90% agreement) for spouses were (1) helping the tired patient in everyday life, (2) stimulating the patient to prevent him/her from giving up and (3) limiting one's amount of personal time to care for the patient.

CONCLUSION

The study identified the key skills needed by spouses of patients being treated for colon cancer. Better awareness of these skills among professionals would enable them to offer tailored support to help patients and spouses maintain their physical and emotional well-being.

Temocillin for febrile urinary tract infections caused by ESBL-producing Enterobacteriaceae in children: a monocentric exposed/non-exposed study

OBJECTIVES

To compare the efficacy of temocillin with standard of care (SOC) for treatment of ESBL-producing Enterobacteriaceae (ESBL-E) febrile urinary tract infection (ESBL-E FUTI) in children.

METHODS

A monocentric retrospective study of children hospitalized with confirmed ESBL-E FUTI from January 2015 to May 2022 was conducted, comparing clinical cure and a 3 month relapse between two groups of patients: 'exposed' patients (EP) and 'non-exposed' patients (NEP) to temocillin. EP received temocillin for at least 3 days. They were matched (1:1 ratio) on age group, sex and presence of uropathy with NEP who received SOC antibiotic therapy.

RESULTS

Thirty-six temocillin-treated children (EP) were matched with 36 SOC children (NEP); 72.2% were under 2 years old (n = 52) and 75.0% had a congenital uropathy (n = 54). EPs had more FUTI history (97.2%, n = 35) than NEPs (61.1%, n = 22) (P < 0.01). Clinical cure rate was 98.6% overall, with no difference between the two groups, as for the FUTI relapse rate, which was 37.1% for EPs versus 27.8% for NEPs (P = 0.45). In bivariate analyses, factors associated with relapses were congenital uropathy (91.3% versus 66.7%, P = 0.04) and subtypes of uropathy, with refluxing uropathy and posterior urethral valves being the more prevalent. Median duration of hospitalization was longer in the EPs (8.0 versus 5.0 days) (P = 0.01).

CONCLUSIONS

The high clinical cure rate and comparable outcomes suggest that temocillin may be an effective therapeutic alternative to standard treatment for ESBL-E FUTI in children.

Juvenile neuropsychiatric systemic lupus erythematosus: A specific clinical phenotype and proposal of a probability score

OBJECTIVE

Juvenile systemic lupus erythematosus (j-SLE) is a rare chronic auto-immune disease involving several organs. Neuropsychiatric (NP) SLE (NPSLE) is frequent in j-SLE and associated with increased morbidity/mortality. Although NPSLE classification criteria exist, attributing NP features to j-SLE remains a major challenge. The study objective is to thoroughly describe j-NPSLE patients and assist in their diagnosis.

METHODS

This is a 4-year retrospective monocentric study of j-SLE patients. NP events were attributed to j-SLE using standardised diagnostic criteria and multidisciplinary paediatric clinical expertise. Clinical features, brain magnetic resonance imaging (MRI)s and samples analysis including cerebrospinal fluid were assessed. A risk of j-NPSLE score was developed based on multivariable logistic regression analysis.

RESULTS

Of 39 patients included, 44% were identified as having j-NPSLE. J-NPSLE diagnosis was established at the onset of j-SLE in 59% of patients. In addition to frequent kidney involvement (76%) and chilblains (65%), all j-NPSLE patients displayed psychiatric features: cognitive symptoms (82%), hallucinations (76%), depressed mood (35%), acute confused state (18%) and catatonia (12%). Neurological involvement was often mild and nonspecific, with headache (53%) in about half of the patients. The main features reported on brain MRI were nonspecific T2/FLAIR white matter hyperintensities (65%), and cerebral atrophy (88%). Upon immunosuppressive treatment, clinical improvement of NP features was observed in all j-NPSLE patients. The score developed to attribute j-NPSLE probability, guide further investigations and appropriate treatments is based on hallucinations, memory, sleep and renal involvement (Sensitivity: 0.95 Specificity: 0.85). Cerebrospinal fluid (CSF) neopterin assessment increases the score sensitivity and specificity.

CONCLUSION

Physicians should carefully and systematically assess the presence of NP features at diagnosis and early stages of j-SLE. For j-NPSLE patients with predominant psychiatric features, a multidisciplinary collaboration, including psychiatrists, is essential for the diagnosis, management and follow-up.

Telehealth-Delivered Program and Accompanying Patients to Enhance the Clinical Condition of Patients Throughout a Liver Transplant: Protocol for a Mixed Methods Study

BACKGROUND

Liver transplantation (LT) is indicated in patients with severe acute or chronic liver failure for which no other therapy is available. With the increasing number of LTs in recent years, liver centers worldwide must manage their patients according to their clinical situation and the expected waiting time for transplantation. The LT clinic at the Centre hospitalier de l'Université de Montréal (CHUM) is developing a new health care model across the entire continuum of pre-, peri-, and posttransplant care that features patient monitoring by an interdisciplinary team, including an accompanying patient; a digital platform to host a clinical plan; a learning program; and data collection from connected objects.

OBJECTIVE

This study aims to (1) evaluate the outcomes following the implementation of a patient platform with connected devices and an accompanying patient, (2) identify implementation barriers and facilitators, (3) describe service outcomes in terms of health outcomes and the rates and nature of contact with the accompanying patient, (4) describe patient outcomes, and (5) assess the intervention's cost-effectiveness.

METHODS

Six types of participants will be included in the study: (1) patients who received transplants and reached 1 year after transplantation before September 2023 (historical cohort or control group), (2) patients who will receive an LT between December 2023 and November 2024 (prospective cohort/intervention group), (3) relatives of those patients, (4) accompanying patients who have received an LT and are interested in supporting patients who will receive an LT, (5) health care professionals, and (6) decision makers. To describe the study sample and collect data to achieve all the objectives, a series of validated questionnaires, accompanying patient logbooks, transcripts of interviews and focus groups, and clinical indicators will be collected throughout the study.

RESULTS

In total, 5 (steering, education, clinical-technological, nurse prescription, and accompanying patient) working committees have been established for the study. Recruitment of patients is expected to start in November 2023. All questionnaires and technological platforms have been prepared, and the clinicians, stakeholders, and accompanying patient personnel have been recruited.

CONCLUSIONS

The implementation of this model in the trajectory of LT recipients at the CHUM may allow for better monitoring and health of patients undergoing transplantation, ultimately reducing the average length of hospital stay and promoting better use of medical resources. In the event of positive results, this model could be transposed to all transplant units at the CHUM and across Quebec (potentially affecting 888 patients per year) but could also be applied more widely to the monitoring of patients with other chronic diseases. The lessons learned from this project will be shared with decision makers and will serve as a model for other initiatives involving accompanying patients, connected objects, or digital platforms.

Mobile app measuring sleep and behaviors: A trial in adolescents with addiction

INTRODUCTION

The smartphones generalisation allows the development of attractive "real-life" monitoring tools for care and research enabling the measurement of addictive behaviours and comorbidities such as sleep disorders. The study objective was to assess the interest of a mobile app collecting such information among adolescents with addictive behaviours in order to enhance the availability of behavioural data in consultation.

METHODS

An open label randomised pilot study was held along two parallel arms. The patients randomised to the intervention group (n=18) used a mobile app to provide daily data for 15 days relating to their sleep and their behaviour (addictive behaviours with or without substances). The patients in the control group (n=18) used a paper diary allowing the collection of the same data, only the medium differed.

RESULTS

The patients' median age was 16 years [15.0-16.5]. A median of 67% and 10% of the expected information was completed respectively in the intervention and control groups during the 15 days of follow-up and could be used in consultation (P=0.08). The patient's knowledge, attitudes, intentions to change, behaviour change and seeking help related to the use of the diaries appeared higher in the intervention group (20.5/30) than in the control group (11/20).

CONCLUSION

This study described the high patient compliance with the data collection by means of the app. The diary app seems to have been more impactful for patients than the paper diary. This app could represent an important tool to improve the therapeutic alliance and care due to a better knowledge of the behaviours on the part of the clinician but also a better awareness of the patients themselves.

Experiences Among Patients With Cystic Fibrosis in the MucoExocet Study of Using Connected Devices for the Management of Pulmonary Exacerbations: Grounded Theory Qualitative Research

BACKGROUND

Early detection of pulmonary exacerbations (PEx) in patients with cystic fibrosis is important to quickly trigger treatment and reduce respiratory damage. An intervention was designed in the frame of the MucoExocet research study providing patients with cystic fibrosis with connected devices and educating them to detect and react to their early signs of PEx.

OBJECTIVE

This study aims to identify the contributions and conditions of home monitoring in relation to their care teams from the users' point of view to detect PEx early and treat it. This study focused on the patients' experiences as the first and main users of home monitoring.

METHODS

A qualitative study was conducted to explore patients' and professionals' experiences with the intervention. We interviewed patients who completed the 2-year study using semistructured guides and conducted focus groups with the care teams. All the interviews were recorded and transcribed verbatim. Their educational material was collected. A grounded analysis was conducted by 2 researchers.

RESULTS

A total of 20 patients completed the study. Three main categories emerged from the patients' verbatim transcripts and were also found in those of the professionals: (1) task technology fit, reflecting reliability, ease of use, accuracy of data, and support of the technology; (2) patient empowerment through technology, grouping patients' learnings, validation of their perception of exacerbation, assessment of treatment efficacy, awareness of healthy behaviors, and ability to react to PEx signs in relation to their care team; (3) use, reflecting a continuous or intermittent use, the perceived usefulness balanced with cumbersome measurements, routinization and personalization of the measurement process, and the way data are shared with the care team. Furthermore, 3 relationships were highlighted between the categories that reflect the necessary conditions for patient empowerment through the use of technology.

CONCLUSIONS

We discuss a theorization of the process of patient empowerment through the use of connected devices and call for further research to verify or amend it in the context of other technologies, illnesses, and care organizations.

Early formative objective structured clinical examinations for students in the pre-clinical years of medical education: A non-randomized controlled prospective pilot study

BACKGROUND

The value of formative objective structured clinical examinations (OSCEs) during the pre-clinical years of medical education remains unclear. We aimed to assess the effectiveness of a formative OSCE program for medical students in their pre-clinical years on subsequent performance in summative OSCE.

METHODS

We conducted a non-randomized controlled prospective pilot study that included all medical students from the last year of the pre-clinical cycle of the Université Paris-Cité Medical School, France, in 2021. The intervention group received the formative OSCE program, which consisted of four OSCE sessions, followed by debriefing and feedback, whereas the control group received the standard teaching program. The main objective of this formative OSCE program was to develop skills in taking a structured medical history and communication. All participants took a final summative OSCE. The primary endpoint was the summative OSCE mark in each group. A questionnaire was also administered to the intervention-group students to collect their feedback. A qualitative analysis, using a convenience sample, was conducted by gathering data pertaining to the process through on-site participative observation of the formative OSCE program.

RESULTS

Twenty students were included in the intervention group; 776 in the control group. We observed a significant improvement with each successive formative OSCE session in communication skills and in taking a structured medical history (p<0.0001 for both skills). Students from the intervention group performed better in a summative OSCE that assessed the structuring of a medical history (median mark 16/20, IQR [15; 17] versus 14/20, [13; 16], respectively, p = 0.012). Adjusted analyses gave similar results. The students from the intervention group reported a feeling of improved competence and a reduced level of stress at the time of the evaluation, supported by the qualitative data showing the benefits of the formative sessions.

CONCLUSION

Our findings suggest that an early formative OSCE program is suitable for the pre-clinical years of medical education and is associated with improved student performance in domains targeted by the program.

Early splenectomy in a large cohort of children with sickle cell anemia: risks and consequences

In children with sickle cell anemia (SCA), early splenic complications can require splenectomy, but the benefit-to-risk ratio and the age at which splenectomy may be safely performed remain unclear. To address this question, we analyzed the rate of post-splenectomy events in children with SCA splenectomized between 2000-2018 at the Robert Debré University Hospital, Paris, France. A total of 188 children underwent splenectomy, including 101 (11.9%) from our newborn cohort and 87 referred to our center. Median (Q1-Q3) age at splenectomy was 4.1 years (range 2.5-7.3 years), with 123 (65.4%) and 65 (34.6%) children splenectomized at ≥3 years of age or <3 years of age, respectively. Median postsplenectomy follow-up was 5.9 years (range 2.7-9.2 years) yielding 1192.6 patient-years (PY) of observation. Indications for splenectomy were mainly acute splenic sequestration (101 [53.7%]) and hypersplenism (75 [39.9%]). All patients received penicillin prophylaxis; 98.3% received 23-valent polysaccharic pneumococcal (PPV-23) vaccination, and 91.9% a median number of 4 (range 3-4) pneumococcal conjugate vaccine shots prior to splenectomy. Overall incidence of invasive bacterial infection and thrombo-embolic events were 0.005 / PY (no pneumococcal infections) and 0.003 / PY, respectively, regardless of age at splenectomy. There was an increased proportion of children with cerebral vasculopathy in children splenectomized <3 years of age (0.037 / PY vs. 0.011 / PY; P<0.01). A significantly greater proportion of splenectomized than non-splenectomized children were treated with hydroxycarbamide (77.2% vs. 50.1%; P<0.01), suggesting a more severe phenotype in children who present spleen complications. If indicated, splenectomy should not be delayed in children, provided recommended pneumococcal prophylaxis is available. Spleen complications in childhood may serve as a marker of severity.

Clinics dedicated to transition preparation for adolescents and young adults with chronic conditions: Factors influencing their use

To pool resources and reduce inequalities in access to transition preparation for patients, transition clinics were created in France. They are places in hospitals, independent of the usual care departments, offering multiple resources and services for adolescents and their parents. Of the 24 physicians from care departments who were surveyed, half of them do not use transition clinics. The implementation of transition clinics in hospitals did not lead to their adoption by the care departments that needed the most support for transition preparation of their patients. A strategy improving adoption is needed to allow transition clinics to reduce inequalities.

Tuberculosis in 0-5-year-old children following TB contact investigations: a retrospective study in a low burden setting

Introduction

We assessed the risk of tuberculosis (TB), the management and the outcomes of 0-5-year-old children after TB contact investigations in a low-burden setting.

Method

All 0-5-year-old children who attended the TB clinic of Robert Debre Hospital, Paris, France, for a TB contact investigation between June 2016 and December 2019 were included in this retrospective study. The risk factors for TB were assessed using univariate and multivariate analyses.

Results

A total of 261 children were included. Forty-six (18%) had TB, including 37 latent tuberculosis infections (LTBIs) and 9 active TB diseases. The prevalence of TB was 21% among high-risk contacts, i.e., household or close contacts and regular or casual contacts. There was no TB among intermediate- or low-risk contacts (0/42). Living under the same roof with (OR: 19.8; 95% CI: 2.6-153), the BCG vaccine (OR: 3.2; 95% CI: 1.2-8.3), contact duration >40 h (OR: 7.6; 95% CI: 2.3-25.3) and sleeping in the room of the index case (OR: 3.9; 95% CI: 1.3-11.7) were independently associated with TB. The BCG vaccine was no longer associated when the analysis was restricted to interferon gamma release assay results. Among children without initial LTBI, antibiotic prophylaxis was not prescribed for 2-5-year-old children or for 32/36 (89%) of 0-2-year-old children who had intermediate- or low-risk contact. Overall, none of these children experienced TB.

Conclusion

In our low prevalence setting, the risk of TB in 0-5-year-old children following a household or close contact was high. Further studies are needed to better assess prophylaxis recommendations in intermediate or low risk contact.

A Smoking Prevention Intervention Among Young People in an Online Community Game: Results from a Pilot Randomized Controlled Trial

Background: Innovative methods for smoking prevention interventions need to be investigated to increase attractiveness, access hard-to-reach populations, and increase effectiveness. We studied the feasibility and immediate effects of an intervention to reinforce norms and behaviors of young people related to antismoking, integrated into a popular online community game. Methods: A pilot randomized controlled trial was conducted through the HABBO online community. The intervention group was exposed to repeated discussion sessions with small groups of peer players and two facilitators once a week for 1 month (four sessions), inside the game. The control group had access to antismoking information websites. Process indicators (attractiveness, participation) and immediate outcomes (norms and intentions with regard to smoking) were assessed by questionnaire. Results: One hundred sixteen players were invited to participate in the intervention; 10 did not meet eligibility criteria, 30 were allocated to the intervention group, and 76 to the control group. Median age was 23. Twenty-four percent were not in education, employment, or training. A median of eight players attended each session and the median number of exchange chats by session was 399; 70% of chat time was occupied by the players. Twenty players attended all four sessions. Immediate norms, representations, and intentions were evaluated in 39 players and showed small differences between groups. Conclusion: Delivering and evaluating a smoking prevention intervention in an online game is feasible. In the targeted online community game, the intervention was attractive and allowed the delivery of innovative interventions to audiences with diverse social profiles. Long-term effects, sustainability, and evaluation methodology are discussed.

Delayed haemolytic transfusion reaction in paediatric patients with sickle cell disease: A retrospective study in a French national reference centre

Delayed haemolytic transfusion reaction (DHTR) is a life-threatening haemolytic anaemia following red blood cell transfusion in patients with sickle cell disease, with only scarce data in children. We retrospectively analysed 41 cases of DHTR in children treated between 2006 and 2020 in a French university hospital. DHTR manifested at a median age of 10.5 years, symptoms occurred a median of 8 days after transfusion performed for an acute event (63%), before surgery (20%) or in a chronic transfusion programme (17%). In all, 93% of patients had painful crisis. Profound anaemia (median 49 g/L), low reticulocyte count (median 140 ×10⁹ /L) and increased lactate dehydrogenase (median 2239 IU/L) were observed. Antibody screening was positive in 51% of patients, and more frequent when there was a history of alloimmunisation. Although no deaths were reported, significant complications occurred in 51% of patients: acute chest syndrome (12 patients), cholestasis (five patients), stroke (two patients) and kidney failure (two patients). A further transfusion was required in 23 patients and corticosteroids were used in 21 to reduce the risk of additional haemolysis. In all, 13 patients subsequently received further transfusions with recurrence of DHTR in only two. The study affords a better overview of DHTR and highlights the need to establish guidelines for its management in children.

Are transition preparation consultations for adolescents with chronic conditions valuable? A mixed-methods study

Our objective was to assess the value of transition preparation consultations (TPC) offered by the AD'venir unit (R. Debré hospital, Paris) as a new service of transitional care, from the perspective of adolescents with chronic conditions (CCs) and their referring healthcare providers (RHCPs). TPCs included a face-to-face interview with pediatricians trained in adolescent medicine, exploring the adolescent's past (CC history), present (daily life, Treatment Burden Questionnaire, family/peer relationships, school, hobbies, sexuality, drugs), and future (global life project, transition, Good2Go questionnaire). The mixed-methods design included the following: a qualitative analysis within a multidisciplinary group (clinicians/sociologists/psychologist/public health researchers) of audio-recordings of TPCs (n = 27/girls = 56%/median age = 17.7 years) and phone interviews with adolescents 2 years post-TPC (n = 26); and a quantitative analysis of the Treatment Burden and Good2Go questionnaires and the benefits perceived by RHCPs (questionnaire 6 months post-TPC). TPCs were a form of training for adult care, adolescents meeting a practitioner alone often for the first time. Naming their CC was difficult. All complained of limitations experienced in social life (diet, fatigue, laboratory/medical appointments), but not the treatment itself; most adolescents willingly talked about sexuality. Adolescents' feelings about transition were various, with poor representations of adult healthcare. Transfer was frequently unplanned. After TPCs, RHCPs modified their practices. Transition in the 2 years post-TPC was usually successful. Conclusion What is Known: • In adolescents with chronic conditions, it is advocated to personalize transition care according to the clinical and social context, pointed out as potentially impacting. • Little is known about the most effective ways to prepare patients according to their needs. What is New: • Based on a global approach to adolescent health, transition preparation consultations are delivered by specially trained physicians. • They are a feasible and valuable way to highlight facilitators and barriers to successful transition and initiate the adolescents' own vision of their future.

Clinical impact of a gastrointestinal PCR panel in children with infectious diarrhoea

OBJECTIVES

Multiplex gastrointestinal PCR (GI-PCR) allows fast and simultaneous detection of 22 enteric pathogens (including Campylobacter, Salmonella, Shigella/enteroinvasive Escherichia coli (EIEC), among other bacteria, parasites and viruses). However, its impact on the management of children with infectious diarrhoea remains unknown.

PATIENTS/DESIGN

All children eligible for stool culture from May to October 2018 were prospectively included in a monocentric study at Robert-Debré University-Hospital.

INTERVENTION

A GI-PCR (BioFire FilmArray) was performed on each stool sample.

MAIN MEASURES

Data on the children's healthcare management before and after GI-PCR results were collected. Stool culture results were also reported.

RESULTS

172 children were included. The main criteria for performing stool analysis were mucous/bloody diarrhoea and/or traveller's diarrhoea (n=130). GI-PCR's were positive for 120 patients (70%). The main pathogens were enteroaggregative E. coli (n=39; 23%), enteropathogenic E. coli (n=34; 20%), Shigella/EIEC (n=27; 16%) and Campylobacter (n=21; 12%). Compared with stool cultures, GI-PCR enabled the detection of 21 vs 19 Campylobacter, 12 vs 10 Salmonella, 27 Shigella/EIEC vs 13 Shigella, 2 vs 2 Yersinia enterocolitica, 1 vs 1 Plesiomonas shigelloides, respectively. Considering the GI-PCR results and before stool culture results, the medical management was revised for 40 patients (23%): 28 initiations, 2 changes and 1 discontinuation of antibiotics, 1 hospitalisation, 2 specific room isolations related to Clostridioides difficile infections, 4 additional test prescriptions and 2 test cancellations.

CONCLUSION

The GI-PCR's results impacted the medical management of gastroenteritis for almostone-fourth of the children, and especially the prescription of appropriate antibiotic treatment before stool culture results.

Evaluation of a new transition organization for young adults with endocrine or metabolic diseases

OBJECTIVE

To evaluate the effect of a new care organization on multiple outcomes of transition success and its cost-effectiveness in patients with any endocrine or metabolic disease diagnosed during childhood and transferred to adult care.

DESIGN

Non-randomized controlled trial in a French university hospital.

METHODS

Patients transferred to adult care during the control period (04/2014-08/2016) and the intervention period (09/2016-06/2018) were included. The intervention is based on case management involving liaising with pediatric services, personalizing care pathways, and liaising with structures outside hospital (general practitioner, educational and social sector). The primary endpoint was the percentage of patients lost to follow-up at 24 months post transfer. Other outcomes were collected from medical files, consultation software, and questionnaires. A cost analysis was performed.

RESULTS

Two hundred two patients were included (101 per period), the most represented pathologies were congenital and non-congenital hypopituitarism (respectively n = 34 (17%) and n = 45 (22%)) and thyroid diseases (n = 21, 10%). Patients were aged 22.5 in median at 24 months post transfer where 12 were lost to follow-up in the control group vs 9 with the intervention (P = 0.49). The percentage of honored consultation among those planned during 24 months was higher with intervention (P = 0.0065). Patient satisfaction, physician trust, and transfer delay did not differ between the groups. The incremental cost-effectiveness ratio was €179 per patient not lost to follow-up.

CONCLUSIONS

At 24 months post transfer, the rate of lost to follow-up did not differ significantly, but indicators of a steadier follow-up were increased and the intervention appeared to be cost-effective.

Feeding disorders in children with oesophageal atresia: a cross-sectional study

INTRODUCTION

With advances in surgical and neonatal care, the survival of patients with oesophageal atresia (OA) has improved over time. Whereas a number of OA-related conditions (delayed primary anastomosis, anastomotic stricture and oesophageal dysmotility) may have an impact on feeding development and although children with OA experience several oral aversive events, paediatric feeding disorders (PFD) remain poorly described in this population. The primary aim of our study was to describe PFD in children born with OA, using a standardised scale. The secondary aim was to determine conditions associated with PFD.

METHODS

The Feeding Disorders in Children with Oesophageal Atresia Study is a national cohort study based on the OA registry from the French National Network. Parents of children born with OA between 2013 and 2016 in one of the 22 participating centres were asked to complete the French version of the Montreal Children's Hospital Feeding Scale.

RESULTS

Of the 248 eligible children, 145 children, with a median age of 2.3 years (Q1-Q3 1.8-2.9, min-max 1.1-4.0 years), were included. Sixty-one children (42%) developed PFD; 13% were tube-fed (n=19). Almost 40% of children with PFD failed to thrive (n=23). The presence of chronic respiratory symptoms was associated with the development of PFD. Ten children with PFD (16%) had no other condition or OA-related complication.

CONCLUSION

PFD are common in children with OA, and there is no typical profile of patients at risk of PFD. Therefore, all children with OA require a systematic screening for PFD that could improve the care and outcomes of patients, especially in terms of growth.

[Supporting the adolescents with chronic condition during transition: Role of the transition units]

The transition of care between pediatric and adult care is a key-period for adolescents with chronic disease, because of the high risk of follow-up loss and of short-term and long-term poorer health. To support transition, platforms of transition have been created in France since several years, implemented in pediatric or adult care structures. Their common objective is to provide a physical reception of adolescents and their parents to share about transition issues, and to inform them about resources to enhance the adolescent's global health. They tend to work closely with the referent health care providers and the patients' associations. A large heterogeneity of functioning and health care supply is still observed in these recent structures. Supporting these structures and reinforcing the partnerships between pediatric and adults care remain a challenge.

Oocyte Vitrification for Fertility Preservation in Women with Benign Gynecologic Disease: French Clinical Practice Guidelines Developed by a Modified Delphi Consensus Process

International guidelines are published to provide standardized information and fertility preservation (FP) care for adults and children. The purpose of the study was to conduct a modified Delphi process for generating FP guidelines for BGD. A steering committee identified 42 potential FP practices for BGD. Then 114 key stakeholders were asked to participate in a modified Delphi process via two online survey rounds and a final meeting. Consensus was reached for 28 items. Among them, stakeholders rated age-specific information concerning the risk of diminished ovarian reserve after surgery as important but rejected proposals setting various upper and lower age limits for FP. All women should be informed about the benefit/risk balance of oocyte vitrification—in particular about the likelihood of live birth according to age. FP should not be offered in rASRM stages I and II endometriosis without endometriomas. These guidelines could be useful for gynecologists to identify situations at risk of infertility and to better inform women with BGDs who might need personalized counseling for FP.

Use of Home-Based Connected Devices in Patients With Cystic Fibrosis for the Early Detection and Treatment of Pulmonary Exacerbations: Protocol for a Qualitative Study

BACKGROUND

Early detection of pulmonary exacerbations (PEx) in patients with cystic fibrosis (CF) is important to quickly trigger treatment and reduce respiratory damage. We hypothesized that using home-based and wearable connected devices (CDs) and educating patients to react in case of abnormal variations in a set of parameters would allow patients to detect and manage their PEx early with their care team.

OBJECTIVE

This qualitative study aimed to assess the feasibility and appropriate conditions of a new PEx management process from the users' point of view by analyzing the experience of patients and of CF center teams regarding the education program, the use of CDs, and the relationship between the patient and the care team during PEx management.

METHODS

We have been conducting a multicenter pilot study involving 36 patients with CF aged ≥12 years. The intervention was divided into 3 phases. In phase 1 (3 months), patients were equipped with CDs, and their parameters were collected on 3 nonconsecutive days each week. Phase 2 involved the development of a "React to PEx" educational program aimed at providing patients with a personalized action plan. A training session to the educational program was organized for the physicians. Physicians then determined the patients' personalized alert thresholds by reviewing the data collected during phase 1 and their patients' clinical history. In phase 3 (12 months), patients were educated by the physician during a clinic visit, and their action plan for reacting in timely fashion to their PEx signs was defined. Education and action plans were revised during clinic visits. At the end of the project, the patients' experience was collected during semistructured interviews with a researcher as part of the qualitative study. The experience of CF teams was collected during focus groups using a semistructured guide once all their patients had finished the study. The interviews and focus groups were recorded and transcribed verbatim to be analyzed. Data from educational sessions were collected throughout the educational program to be put into perspective with the learnings reported by patients. Analyses are being led by 2 researchers using NVivo (QSR International).

RESULTS

The study received the favorable reception of the Committee for the Protection of Persons (CPP NORTH WEST III) on June 10, 2017 (#2017-A00723-50). Out of the 36 patients included in phase 1, 27 were educated and entered phase 3. We completed collection of all data from the patients and care providers. Qualitative analysis will provide a better understanding of users' experience on the conditions of data collection, how useful CDs are for detecting PEx, how useful the PEx action plan is for reacting quickly, what patients learned about PEx management, and the conditions for this PEx management to be sustainable in routine care.

CONCLUSIONS

This study will open new perspectives for further research into the implementation of an optimal PEx care process in the organization of care teams in order to support patient self-management.

P–454 Oocyte vitrification for fertility preservation in women with benign gynecological disease: French national clinical guidelines with a modified Delphi consensus process

Study question

Is there consensual clinical practices about fertility preservation (FP) for benign gynecological diseases BGD)?

Summary answer

A consensus study using the modified Delphi method identified 28 consensual practices concerning oocyte vitrification for fertility preservation in women with benign gynecological disease.

What is known already

Clinical Practical international guidelines are still published in oncology for offering standardized information and care for adults and children with cancer. Recently, the ESHRE Female Fertility Preservation Guideline Development Group published recommendations for healthcare professionals involved in fertility preservation for post-pubertal women and transgender adolescents and young adults. However, benign gynecological indications weren’t distinctly individualized of malignant conditions. There’s a lack of large cohort studies assessing the risks and outcome of FP for benign gynecological diseases. Healthcare professionals need consensus for defining the “good” indications of FP for benign gynecological diseases that could impair fertility.

Study design, size, duration

A steering group composed by 14 healthcare professionals and a patient representative with lived experience of endometriosis identified 42 potential practices concerning fertility preservation for benign gynecological disease. Then, 114 key stakeholders including various healthcare professionals (n = 108) and patient representatives(n = 6) were asked to answer at two rounds of a modified Delphi via an online survey from February to September 2020.

Participants/materials, setting, methods

Participants had to score 42 items for the first round and 31 for the second round using a nine-point Likert scale. These statements were distributed into five categories: Information to deliver to age-reproductive women with a BGD (n = 9), technical aspect of fertility preservation for BGD (n = 6), indications of FP for endometriosis (n = 13), indications of FP for none-endometriosis BGD (n = 10), idiopathic diminished ovarian reserve in the absence of gynecologic and endocrinologic diseases (n = 4).

Main results and the role of chance

Survey response of stakeholders was 75% (86 out of 114) for the round 1 and 87% (75 out of 86) for the round 2. Consensus recommendations were achieved for 28 items, and no consensus between stakeholders was achieved in the remaining items. Stakeholders rated the importance of an age-specific information concerning the risk of diminished ovarian reserve after surgery and the necessity to inform about the benefice/ risk balance of oocyte vitrification, in particular about the chance of live-birth according to the age at the time of oocyte vitrification. They endorsed oocyte vitrification as the reference FP technique for those benign indications. Experts rejected to determine lower and upper age limits in women for fertility preservation. FP shouldn’t be offered in rAFS stages I and II endometriosis without endometriomas.

Limitations, reasons for caution

Experts were only French native speakers from France, and Belgium. It would have been interesting to conduct this survey with experts from other continents.

Wider implications of the findings: At our knowledge, we present here the first guideline s focusing on FP in women with BGD, following a designed scientific Delphi procedure. These guidelines could be useful for gynecologists to better inform women with benign gynecological diseases about the indication or not to offer a FP procedure.

Peripheral obstruction without airflow limitation is rare and not specific to asthma in children

Peripheral (or small) airway obstruction (PAO) is considered a marker of childhood asthma but the techniques able to directly measure it are rarely used in routine. Usual spirometry and plethysmography can detect a certain degree of PAO when reduced forced vital capacity (FVC) is associated to normal forced expiratory volume in 1 s (FEV₁ ) to FVC ratio, and normal total lung capacity (TLC). The frequency of this functional pattern has never been studied in different pediatric respiratory conditions. To assess the prevalence and outcome of PAO in children with different diseases or symptoms, we retrospectively extracted from our database all files of Caucasian subjects encompassing spirometry and plethysmography measurements. Spirometry patterns (normal, airflow limitation [AFL; low FEV₁ /FVC], low FVC [with normal FEV₁ /FVC]) and final functional patterns (normal, AFL, PAO, restrictive [low TLC], or mixed) were described. We included 4394 files recorded in 1794 children (median [IQR] age: 10.7 [9.2-12.9] years). At inclusion, 125 (7%) children had low FVC of which 56 (44.8%, and 3.1% [95% CI 2.3-3.9] of the whole population) had PAO. PAO prevalence increased with age (OR (95% CI) per 2-year-increase: 2.26 (1.59-3.23); p < .001), and was more frequent in chronic bronchial diseases other than asthma (1.6% vs. 8.0%). On repeated tests, PAO frequently normalized (26.1%) or persisted (43.5%), but it less often progressed into AFL (13%) or restrictive (13%) patterns. PAO is an infrequent nonspecific and persistent functional pattern. Its prevalence increases with age and in diagnosis of chronic respiratory diseases other than asthma.

Neuropathic Pain in Children with Sickle Cell Disease: The Hidden Side of the Vaso-Occlusive Crisis

The majority of hospitalizations of patients with sickle cell disease (SCD) are related to painful vaso-occlusive crises (VOCs). Although the pain of VOC is classically nociceptive, neuropathic pain (NP) has also been demonstrated in SCD patients. The aim of our study is to specify the prevalence of NP during VOCs in SCD children using a dedicated scale and to measure its characteristics. We performed a prospective study that included SCD children hospitalized for an acute VOC. The presence of NP was sought with the DN4 scale on the second and fourth days of hospitalization. A total of 54 SCD children were included in the study. Overall, 41% of the patients (n = 22) experienced neuropathic pain during the VOC, mostly at an early stage (Day 2). The median age, the sex ratio, the location of the pain, and the morphine consumption were similar for patients with and without NP. Our study shows that neuropathic pain is very common during VOCs in SCD children. The absence of identified risk factors should prompt us to be vigilant regardless of the patient's age, sex, and clinical presentation.

A governmental program to encourage medical students to deliver primary prevention: experiment and evaluation in a French faculty of medicine

BACKGROUND

A public health student service was set up by the French government in 2018 with the aim of increasing awareness of primary health promotion among the 47,000 students of medicine and other health professions. It is an annual program involving community-based actions on nutrition, physical activity, addiction or sexuality. Our objective was to evaluate its implementation at local level and the different experiences of the stakeholders.

METHODS

A quasi-experimental study using process evaluation was performed in a Faculty of Medicine in Paris. Quantitative and qualitative data were collected from medical students who carried out preventive health actions, in the institutions in which the actions took place and from a subsample of beneficiaries.

RESULTS

One hundred and eight actions were carried out by 341 students in 23 educational or social institutions, mostly high schools (n = 12, 52%). Two thirds of the students did not feel sufficiently prepared to deliver preventive health interventions (65.7%, 224/341); however the beneficiaries found that the interventions were good (278/280, 99,2%). Nineteen (83%) of the host institutions agreed to welcome health service students again, of which 9 required some modifications. For students, the reporting of a satisfactory health service experience was associated with the reporting of skills or knowledge acquisition (p < 0.01). Delivering actions in high schools and to a medium-sized number of beneficiaries per week was associated with students' satisfaction. No effect of gender or theme of prevention was observed. For 248/341 (72.7%) students, the public health service program prompts them to address prevention issues in the future.

CONCLUSION

The public health service undertaken by medical students through the program is a feasible and acceptable means of delivering preventive actions. Reinforcement of training and closer interaction with the host institutions would improve results.

Transition of young adults with endocrine and metabolic diseases: the 'TRANSEND' cohort

OBJECTIVE

The transition from paediatric to adult medicine involves risks of poor patient outcomes and of significant losses of patients to follow up. The research aimed to analyse the implementation in an initial cohort of patients of a new programme of transition to adult care based on a case management approach.

DESIGN

A longitudinal study of the case management approach to transition, initiated in a university hospital in France in September 2016.

METHODS

Patients with the endocrine or metabolic disease diagnosed during childhood and transferred to adult care were included. The transition programme includes three steps based on case management: liaising with paediatric services, personalising care pathways, and liaising with structures outside the hospital (general practitioners, agencies in the educational and social sector).

RESULTS

The cohort included 500 patients, with malignant brain tumour (n = 56 (11%)), obesity (n = 55 (11%)), type 1 diabetes (n = 54 (11%)), or other disease (n = 335 (67%)). Their median age at transfer was 19, and the sex ratio was 0.5. At median 21 months of follow-up, 439 (88%) had a regular follow-up in or outside the hospital, 47 (9%) had irregular follow-up (absence at the last appointment or no appointment scheduled within the time recommended), 4 had stopped care on doctor's advice, 4 had died, 3 had moved, and 3 had refused care. The programme involved 9615 case management actions; 7% of patients required more than 50 actions. Patients requiring most support were usually those affected by a rare genetic form of obesity.

CONCLUSIONS

Case managers successfully addressed the complex needs of patients. Over time, the cohort will provide unprecedented long-term outcome results for patients with various conditions who experienced this form of transition.

Practical generic guidelines for paediatric-to-adult transition for adolescents with chronic disease

BACKGROUND

The last 20 years have seen many attempts to improve transition to adult healthcare for adolescents with chronic disease, but there is currently no established consensus on generic practices. Our goal was to identify relevant and pragmatic guidelines for transition practice for each step of this process (before, during and after transfer), applicable to a wide range of chronic illnesses and health services, via a participatory approach involving all the key stakeholders.

METHODS

We conducted interviews and a literature review to elaborate a questionnaire for use in an online 2-round Delphi survey. The survey panel included 36 French health and social professionals from different care settings, and young adults and parents with an experience of healthcare transition related to all types of chronic disease.

RESULTS

The survey consensus identified 19 items on feasibility and relevance criteria, which form the guidelines. It is composed of five practices to be adopted during preparation in paediatrics, seven practices in the active phase of transition and seven in adult care. Two guidelines achieved complete consensus: having a longer consultation for the first appointment with the adult doctor, and keeping the same adult doctor throughout follow-up. A further 36 items met the criterion of relevance, but were deemed unfeasible.

CONCLUSIONS

Taking into account all stakeholder views and the real-world applicability of care practices enabled us to elaborate consensual guidelines whose implementation requires no additional health service resources.

International consensus validation of the POPI tool (Pediatrics: Omission of Prescriptions and Inappropriate prescriptions) to identify inappropriate prescribing in pediatrics

INTRODUCTION

While drug prescription should be based on established recommendations stemming from clinical trials but in pediatrics, many drugs are used without marketing authorization. Consequently recommendations are often based on clinical experience and the risk of inappropriate prescription (IP) is high. A tool for detecting IP in pediatrics-called POPI (Pediatrics: Omission of Prescriptions and Inappropriate prescriptions)-has been developed in France. However the relevance of its use at an international level is not known. Our aim has been to adapt POPI for a worldwide use.

MATERIAL AND METHOD

A two-round Delphi online questionnaire was completed and validated by international experts to identify consensual items. They were asked to rate the validity of each items taking into account the recommendations and practices in their countries. Only propositions obtaining a median score in the upper tertile with an agreement of more than 75% of the panel-for the first round-and 85%-for the second round-were retained.

RESULTS

Our panel included 11 pharmacists (55%) and 9 physicians (45%). The panelists came from 12 different countries: England, Belgium, Brazil, Canada, China, Ivory Coast, Ireland, Malaysia, Portugal, Switzerland, Turkey and Vietnam. At the end of the first round, of the 105 items of the original POPI tool, 80 items were retained including 16 items reworded and 25 items were deleted. In the second round, 14 experts participated in the study. This final international POPI tool is composed of 73 IP and omissions of prescriptions in the fields of neuropsychiatry, dermatology, infectiology, pneumology, gastroenterology, pain and fever.

DISCUSSION AND CONCLUSION

This study highlights international consensus on prescription practice in pediatrics. The use of this tool in everyday practice could reduce the risk of inappropriate prescription. The impact of the diffusion of POPI tool will be assessed in a prospective multicentric study.

Respiratory pathogens and acute chest syndrome in children with sickle cell disease

BACKGROUND

Acute chest syndromes (ACS) may be associated with upper respiratory tract infections, but the epidemiology of viral and intracellular respiratory pathogens in children with sickle cell disease (SCD) is not precisely known. The aim of this study was to describe the epidemiology of viral and intracellular respiratory pathogens in children with SCD presenting with fever and/or ACS.

MATERIALS AND METHODS

An observational, prospective, single-centre cohort study with nested case-control analysis was conducted on children with SCD admitted from October 2016 to October 2017 for fever and/or ACS to the paediatric department of Robert Debré university hospital, Paris, France. They were screened for 20 respiratory pathogens by a multiplex PCR in the nasopharynx (FilmArray).

RESULTS

We included 101 children. M/F sex ratio of 0.45. The median age was 3.2 years (IQR: 1.4-8.2). At least one pathogen was isolated in 67 patients (67%). The most frequent viruses were as follows: rhinovirus (n=33), adenovirus (n=14), respiratory syncytial virus (n=13) and parainfluenza viruses (n=11). Mycoplasma pneumoniae was detected in one case. Twenty-three (23%) presented with or developed ACS. A nested case-control analysis was performed, after pairing ACS with non-ACS children for age and inclusion period. There was no statistical association between any viral detection or multiple viral infection, and ACS (p=0.51) even though parainfluenza viruses were twice as common in ACS.

CONCLUSIONS

Viral detection in febrile children with SCD is frequent, but its association with ACS was not demonstrated. In this study, M. pneumoniae was rare in young children with SCD experiencing ACS.

MON-LB308 Studying the Care and Social Pathway of Young Adults With Endocrine and Metabolic Diseases During Transition: The “Transend” Cohort

Context. The transition period between pediatric and adult medicine is associated with poor patient outcomes and an important number of patients lost to follow up. Intervention exist but the few published randomized trials do not allow to study long-term patient outcomes nor intervention sustainability in time. Objective. Describe the cohort of patients in adult care who benefit from a new transition program based on case management approach, its activity and follow-up outcomes. Methods. A longitudinal study was led since September 2016 in adult services of endocrinology, nutrition and diabetology of a French University Hospital. Patients with any endocrine disease diagnosed during childhood and transferred to adult care were included. The care pathway for these patients was built in three steps. Step 1 is dedicated in liaising with pediatric services and patient to facilitate its first visit in adult care. Step 2 defines the care pathway in adult service based on the needs assessment realized by the coordinator upon the patient’s arrival in adult service. Step 3 focuses in liaising with structures outside hospital (GP, educational and social sector). Thorough the follow-up, the coordinator is identified as the key contact by the patients. Attendance to medical appointments, clinical, and social data are collected throughout patient follow-up. Results. Since 3 years, 500 patients benefited from the case management mainly for their obesity (n=91, 18%), type 1 diabetes (n=54, 11%), malignant brain tumor (n=68, 14%) or congenital hypopituitarism (n=42, 8%). They were aged 19 in median at transfer in adult care, sex ratio: 0,5, A large majority live in the parental home (409, 82%), 169 (34%) are university students, 130 (26%) are in high school, 90 (18%) are in medico-social institution. Patients who required most of support from the coordinator usually combine one (or more) somatic disease and either a neuro-cognitive disorder or a psychiatric disorder, they all have social difficulties. In patients with more than 3 months of follow-up (median: 18 months), 22/418 (5%) are out of follow-up. Concerning the patients for whom the follow-up is 36 months or more, the percentage of out of lollow-up is the same: 5% Conclusions. The case manager addresses the complex needs of diverse patients. With time, the cohort will provide unprecedented long-term results of patients with various conditions who went through transition.

Validation of the "Good2Go": the first French-language transition readiness questionnaire

The use of transition readiness questionnaires is strongly recommended in adolescents with chronic conditions. The aim of our study was to validate "Good2Go," the first French-language transition readiness questionnaire. We analyzed the data from 2 multicentric studies (Canada and France) involving adolescents with chronic conditions (type 1 diabetes, inflammatory bowel disease, cystic fibrosis, epilepsy, juvenile idiopathic arthritis). Content and construct validity were examined using factorial and Rasch analysis (structural validity), Spearman's correlation, and Mann-Whitney test (external validity). Cronbach's α and intra-class correlation coefficients explored reliability. Cognitive interviews assessed wording comprehension and item appropriateness. Good2Go was completed by 321 participants (boys = 51%; mean age = 16.4 years (standard deviation = 1.5; min = 14.0; max = 18.0); Canada = 51.1%). Factor analysis identified 3 domains: "health self-advocacy," "knowledge about chronic conditions," and "self-management skills." The 3-domain structure showed a satisfying Rasch fit, internal consistency, and test-retest reliability. Good2Go domain scores were significantly higher in participants over 17 years of age, indicating satisfactory external validity.Conclusion: Good2Go is a valid 20-item questionnaire to assess transition readiness in adolescents with chronic conditions and may be useful in routine care to propose individually tailored preparation for their transfer to adult healthcare. Further research is now needed to analyze correlation between domain scores and success of transition.What is Known:• In adolescents with chronic conditions, the use of transition readiness questionnaires is recommended to propose individually tailored preparation for their transfer to adult healthcare.• However, no French-language questionnaire has been so far validated.What is New:• Based on a complete validation methodology, this study highlights that the French-language 20-items Good2Go questionnaire has good psychometric properties.• It explores all transition key points though 3 scored domains: "health self-advocacy", "knowledge about chronic disease" and "self-management skills".

Non-inferiority double-blind randomised controlled trial comparing gabapentin versus tramadol for the treatment of chronic neuropathic or mixed pain in children and adolescents: the GABA-1 trial-a study protocol

INTRODUCTION

Gabapentin is currently used 'off-label' in children and adolescents with chronic neuropathic pain, and reliable evidence of its effects and optimal dosing are lacking.

OBJECTIVES

The GABA-1 trial aims to compare the efficacy and safety of gabapentin liquid formulation relative to tramadol and to explore the pharmacokinetics of both drugs in the treatment of chronic, neuropathic or mixed pain in the paediatric population.

METHODS AND ANALYSIS

The trial is a multicentre, double-blind, double-dummy, randomised, active-controlled, non-inferiority trial. Participants aged from 3 months to <18 years of age with moderate to severe (≥4/10 in age-appropriate pain scales) chronic neuropathic or mixed pain will be recruited in 14 clinical sites in eight European countries. A total of 94 subjects will be randomised to receive gabapentin and tramadol placebo or tramadol and gabapentin placebo throughout 16-19 weeks (including 3 weeks of titration [optimisation period], 12 weeks of treatment at a stable dose [maintenance period] and 1-4 weeks of tapering [discontinuation period]). The primary objective is to assess the efficacy of gabapentin relative to tramadol for the treatment of moderate to severe chronic neuropathic or mixed pain by comparing the difference in average pain scores (assessed by age-appropriate pain scales) between intervention arms after 15 weeks of treatment. Secondary objectives include the assessment of the safety, quality of life and global satisfaction with treatment and the description of the pharmacokinetic-pharmacodynamic relationship of gabapentin liquid formulation and tramadol oral drops to validate the recommended paediatric doses. Only rescue pain medication by paracetamol and/or ibuprofen is allowed during the trial.

ETHICS AND DISSEMINATION

Ethic approval was obtained in the eight participating countries. Results will be submitted for publication in a peer-reviewed journal and presented at one or more scientific conferences.

Exploring how non-inferiority and equivalence are assessed in paediatrics: a systematic review

OBJECTIVE

To review characteristics, methodology and reporting of non-inferiority and equivalence trials in the specific context of paediatrics.

DESIGN

PubMed and Cochrane databases were searched (up to September 2016) for non-inferiority/equivalence randomised controlled trials conducted in children published in high-impact-factor journals (>5.0 for general/specialist medical journals; >2.2 for paediatric journals).

RESULTS

We found that the statistical hypothesis was inconsistent with the objective in 12 (10%) of the 125 reports included. Non-inferiority (n=98) and equivalence trials (n=27) were mostly used to evaluate interventions with easier administration (45%, n=54/120) and/or better safety profile (34%, n=41/120). All the data needed for targeted sample size recalculation were available for 39 reports (31%). The margin-representing the largest difference between arms that would be clinically acceptable-was reported in 119 (95%), and 44/119 (37%) reported the method used for margin determination. The median sample size was 268 (IQR 125-531). Margins were wider in smaller trials (<125 randomised patients) than in larger trials (p=0.04/p<0.01 for binary/continuous outcomes, respectively). We did not agree with the authors' conclusions in 11% (11/103) of the reports that provided sufficient information.

CONCLUSIONS

There is still a need to improve the quality of methodology, reporting and interpretation of non-inferiority/equivalence trials in paediatrics. In particular, the margins were often not justified and the conclusion was often not supported by the design and/or the results. As researchers have to cope with small sample size and with lack of evidence, methods for non-inferiority/equivalence trials need to be used and/or developed in this vulnerable population.

Professional's Perspectives on Care Management of Young People with Perinatally Acquired HIV during Transition: A Qualitative Study in Adult Care Setting

Background

Increasing numbers of young people with perinatally acquired HIV are surviving to adulthood. When they come of age, they leave pediatric services in which they were followed and have to be transferred to the adult health care system. Difficulties in adaptation to adult care and the numbers of young people lost to follow up after transfer to adult care have been reported. This transition phase and their retention in adult care are crucial in maintaining the clinical status of these young with HIV in adulthood. Our study aimed to explore how HIV professionals working in adult care perceive and adapt their practices to young people in transition.

Methods

Qualitative interviews were conducted with 18 health and social services professionals in hospitals or patient associations in France. A thematic analysis was conducted.

Results

Adult care professionals were found to be making a distinction between these young people and their patients who were infected during adulthood. On the basis of the healthcare teams’ experience, a simplified categorization of these young people into four levels can be used: those “who have everything good”; those who have some deficiencies that must be addressed; those “who have everything bad”; and those lost to follow up. Professionals interviewed highlighted the difficulties they encountered with young people in transition. Three types of problematic situations were identified: problems of acceptance of the disease; communication problems; and problems of disorientation in the new care environment.

Conclusions

Despite the lack of specific training or national policy recommendations for the integration of young people with perinatally acquired HIV into adult services, all the adult healthcare teams interviewed tried to adapt their practice to this population. The results suggested that professional involvement during transition should depend on the characteristics of the patient, not be limited to a single transition model and that a dedicated structure for transition care is not appropriate for all young people.
