Core outcome set for uncomplicated acute appendicitis in children and young people.

BACKGROUND: Research studies to inform clinical practice and policy in children and young people with appendicitis are hampered by inconsistent selection and reporting of outcomes. The aim of this study was to develop a core outcome set for reporting all studies of uncomplicated acute appendicitis in children and young people. METHODS: Systematic literature reviews, qualitative interviews with parents and patients treated for uncomplicated acute appendicitis, and a Study-Specific Advisory Group informed a long list of outcomes. Outcomes were then prioritized by stakeholders based in the UK (patients, parents, and paediatric and general surgeons) in an online three-round Delphi consensus process, followed by face-to-face consensus meetings. RESULTS: A long list of 40 items was scored by 147 key stakeholders in the first Delphi round, of whom 90 completed the two subsequent Delphi rounds. The final core outcome set comprises 14 outcomes: intra-abdominal abscess, reoperation (including interventional radiology procedure), readmission to hospital, bowel obstruction, wound infection, antibiotic failure, wound complication, negative appendicectomy, recurrent appendicitis, death, patient stress/psychological distress, length of hospital stay, time away from full activity and child's quality of life. CONCLUSION: A core outcome set comprising 14 outcomes across five key domains has been developed for reporting studies in children and young people with uncomplicated acute appendicitis. Further work is required to determine how and when to measure these outcomes.

ANTECEDENTES: Los estudios de investigación que sirvan de base para la práctica clínica y la política en niños y adultos jóvenes con apendicitis se ven obstaculizados por inconsistencias en la selección y descripción de los resultados. El objetivo de este estudio fue desarrollar un conjunto central de resultados para todos los estudios de apendicitis aguda no complicada en niños y adultos jóvenes. MÉTODOS: Para establecer una lista de resultados se efectuaron revisiones sistemáticas de la literatura, entrevistas cualitativas con padres y pacientes tratados por apendicitis aguda no complicada, y consulta con un Grupo de Asesoramiento Específico para el Estudio. Seguidamente, los resultados se priorizaron de acuerdo con los intereses de las partes interesadas (pacientes, padres, y cirujanos pediátricos y generales) en el Reino Unido a través de un proceso de consenso Delphi de tres rondas en Internet, seguido de reuniones personales de consenso. RESULTADOS: Un total de 147 participantes puntuaron una larga lista de 40 ítems en la primera ronda Delphi, de los cuales 90 completaron las dos rondas Delphi subsiguientes. El conjunto final incluye 14 resultados: absceso intra-abdominal, reoperación (incluyendo procedimientos radiológicos intervencionistas), reingreso, obstrucción intestinal, infección de herida, otras complicaciones de la herida, fracaso del tratamiento con antibióticos, apendicectomía blanca, apendicitis recidivante, muerte, estrés del paciente/sufrimiento psicológico, duración de la estancia hospitalaria, tiempo alejado de todas sus actividades y calidad de vida. CONCLUSIÓN: Se ha desarrollado un conjunto central de resultados que incluye 14 resultados en cinco dominios clave para la descripción de estudios en niños y adultos jóvenes con apendicitis aguda no complicada. Se requieren más trabajos para determinar cómo y cuándo conviene medir estos resultados.

The identification of key indicators to drive quality improvement in obstetric anaesthesia: results of the Obstetric Anaesthetists' Association/National Perinatal Epidemiology Unit collaborative Delphi project.

A three-stage Delphi survey process was undertaken to identify the quality indicators considered the most relevant to obstetric anaesthesia. The initial quality indicators assessed were derived from national peer-reviewed publications and were divided into service provision, service quality and clinical outcomes. A range of stakeholders were invited to participate and divided into three panels: obstetric anaesthetists; other maternity care health professionals; and women who had used maternity services. In total, 133 stakeholders registered to participate with 80% completing all three phases of the survey process. Participants ranked indicators for their relative importance using the grading of recommendations assessment, development and evaluation scale. From an initial list of 31 quality indicators, 11 indicators were rated as extremely important by > 90% of participants in at least two panels. These 11 indicators were presented to stakeholders; they were asked to vote for the five indicators they considered most relevant and useful for assessing and benchmarking the quality of obstetric anaesthesia provided. The indicators chosen were: the percentage of women who had an epidural/combined spinal-epidural for labour analgesia with accidental dural puncture; the presence of guidelines for the referral of patients to an anaesthetist for antenatal review; whether there are dedicated elective caesarean section lists; the availability of point-of-care testing for estimation of haemoglobin concentration; and the percentage of epidurals for labour analgesia that provided adequate pain relief within 45 min of the start of epidural insertion. These indicators may be used for quality improvement and national benchmarking to support the implementation of quality standards in obstetric anaesthesia.

Systematic review and meta-analysis comparing outcomes following orchidopexy for cryptorchidism before or after 1 year of age.

BACKGROUND: Current guidelines recommend orchidopexy for cryptorchidism by 12 months of age, yet this is not universally adhered to. The aim of this systematic review and meta-analysis was to compare outcomes between orchidopexies performed before and after 1 year of age. METHODS: MEDLINE and Embase were searched (September 2015) using terms relating to cryptorchidism, orchidopexy and the outcomes of interest. Studies were eligible for inclusion if they compared orchidopexy at less than 1 year of age (early) with orchidopexy at 1 year or more of age (delayed) and reported the primary outcome (testicular atrophy) or one of the secondary outcomes (fertility potential, postoperative complication, malignancy). Studies were excluded when more than 50 per cent of infants had intra-abdominal testes, or the population included infants with disorders of sexual differentiation. Additional studies were identified through reference list searching. Unpublished data were sought from the ORCHESTRA study investigators. RESULTS: Fifteen eligible studies were identified from 1387 titles. There was no difference in atrophy rate between early orchidopexy and delayed orchidopexy (risk ratio 0·64, 95 per cent c.i. 0·25 to 1·66; 912 testes). Testicular volume was greater (mean difference 0·06 (95 per cent c.i. 0·01 to 0·10) ml; 346 testes) and there were more spermatogonia per tubule (mean difference 0·47 (0·31 to 0·64); 382 testes) in infants undergoing early orchidopexy, with no difference in complication rate (risk ratio 0·68, 0·27 to 1·68; 426 testes). No study reported malignancy rate. CONCLUSION: Atrophy and complication rates do not appear different between early and delayed orchidopexy, and fertility potential may be better with early orchidopexy. Imprecision of the available data limits the robustness of these conclusions.

Developing a set of consensus indicators to support maternity service quality improvement: using Core Outcome Set methodology including a Delphi process.

OBJECTIVE: To develop a core metric set to monitor the quality of maternity care. DESIGN: Delphi process followed by a face-to-face consensus meeting. SETTING: English maternity units. POPULATION: Three representative expert panels: service designers, providers and users. MAIN OUTCOME MEASURES: Maternity care metrics judged important by participants. METHODS: Participants were asked to complete a two-phase Delphi process, scoring metrics from existing local maternity dashboards. A consensus meeting discussed the results and re-scored the metrics. RESULTS: In all, 125 distinct metrics across six domains were identified from existing dashboards. Following the consensus meeting, 14 metrics met the inclusion criteria for the final core set: smoking rate at booking; rate of birth without intervention; caesarean section delivery rate in Robson group 1 women; caesarean section delivery rate in Robson group 2 women; caesarean section delivery rate in Robson group 5 women; third- and fourth-degree tear rate among women delivering vaginally; rate of postpartum haemorrhage of ≥1500 ml; rate of successful vaginal birth after a single previous caesarean section; smoking rate at delivery; proportion of babies born at term with an Apgar score <7 at 5 minutes; proportion of babies born at term admitted to the neonatal intensive care unit; proportion of babies readmitted to hospital at <30 days of age; breastfeeding initiation rate; and breastfeeding rate at 6-8 weeks. CONCLUSIONS: Core outcome set methodology can be used to incorporate the views of key stakeholders in developing a core metric set to monitor the quality of care in maternity units, thus enabling improvement. TWEETABLE ABSTRACT: Achieving consensus on core metrics for monitoring the quality of maternity care.

A single center experience of abdominal wall graft rejection after combined intestinal and abdominal wall transplantation.

We report our outcomes following combined intestinal and abdominal wall transplantation, focusing on the presentation and treatment of acute rejection of the abdominal wall vascularized composite allograft (VCA). Retrospective analysis of all patients with combined intestinal/VCA transplantation was undertaken. Graft abnormalities were documented photographically and biopsies taken, with histological classification of rejection according to Banff 2007 guidelines. We have performed five combined intestinal and abdominal wall transplants to date. Two patients developed erythematous, maculopapular to papular eruptions confined to the VCA, histologically confirmed as grade II/III rejection, yet with normal bowel on endoscopy. Both patients' rashes resolved within 72 h of increasing immunosuppressive treatment. One patient later developed a recurrence of the rash, confirmed as skin rejection, but did not immediately seek medical attention. Treatment was therefore delayed, and mild intestinal rejection developed. We describe the rash associated with VCA rejection, and propose that while the skin of an abdominal wall VCA may reject independently of the intestinal allograft, delay in treatment of rejection episodes may result in rejection of the intestinal graft.
