Quality/risk management system in radiotherapy: Changes afoot.

The French sanitary and regulatory context in which radiotherapy centres are comprised is evolving. Risk and quality management systems are currently adapting to these evolutions. The French nuclear safety agency (ASN) decision of July 1st 2008 on quality assurance obligations in radiotherapy has reached 10 years of age, and the French high authority of health (HAS) certification system 20 years now. Mandatory tools needed for the improvement of quality and safety in healthcare are now well known. From now on, the focus of healthcare policies is oriented towards evaluation of efficiency of these new organisations designed following ASN and HAS nationwide guidelines.

AUDCRED: ferramenta de apoio para auditoria de contas em saúde / AUDCRED: support tool for auditing health accounts

Introdução: Uma das ferramentas de qualidade mais eficientes para monitorar um sistema de gestão é a auditoria, pois, quando bem aplicada, diagnostica não conformidades no serviço avaliado, sendo executada por profissionais capacitados que apresentam, além do conhecimento técnico-científico, atributos pessoais como imparcialidade, prudência e diplomacia. Objetivos: O objetivo geral do estudo foi desenvolver uma ferramenta móvel que possa servir de apoio para o processo de auditoria de contas médicas e os objetivos específicos foram: identificar os requisitos necessários para o desenvolvimento da ferramenta de auditoria; apresentar um protótipo e desenvolver uma ferramenta garantindo os requisitos de segurança necessários à manutenção da informação pessoal, possibilitando sua implementação, distribuição e modificação e avaliar o impacto da ferramenta para a auditoria em saúde no âmbito da Marinha do Brasil. Método: Trata-se de um estudo descritivo, exploratório, de abordagem qualitativa, aplicado à produção tecnológica e destinado a desenvolver uma ferramenta informatizada móvel para apoio ao serviço de auditoria de contas médicas. Para desenvolvimento da ferramenta foi utilizada a metodologia de Pressman, seguindo as seguintes etapas: coleta e refinamento dos requisitos, elaboração de projeto rápido, construção do protótipo, avaliação pelo cliente e posterior refinamento quando há necessidade de ajustes finais do projeto, com o intuito de satisfazer da melhor forma as necessidades dos clientes. Resultados: Foram distribuídos 75 formulários para os auditores da Marinha e, tendo sido respondidos 65 (84,3%), observou-se que 40,9% dos entrevistados eram enfermeiros e 29% não tinham experiência em auditoria. As falas dos entrevistados foram analisadas, emergindo cinco categorias relacionadas a melhorias e uma a crítica, sendo estas respectivamente: ampliar o módulo para controle e previsão de custos; regular os serviços que serão prestados pela contratada; orientar profissionais a executarem a auditoria em saúde; ampliar módulo para que possam ser apresentados indicadores e relatório; disponibilizar mais informações sobre os credenciados e não entender o propósito da ferramenta. Conclusão: Acredita-se que a ferramenta irá contribuir para que os auditores recém-ingressos na Marinha possam executar o processo de auditoria de acordo com a técnica, gerando uniformidade, dando celeridade e, principalmente, evitando perdas para a organização. Dessa forma, favorecendo ao profissional mais habilidade e destreza em todo processo

Introduction: One of the most efficient quality tools to monitor a management system is the audit, because, when properly applied, it diagnoses non-conformities in the service evaluated, being performed by trained professionals who have, in addition to technical-scientific knowledge, personal attributes such as impartiality, prudence and diplomacy. The general objective of the study was to develop a mobile tool that can support the medical bills audit process and the specific. Objectives: The general objective of the study was to develop a mobile tool that can support the medical bill audit process and the specific objectives were: to identify the necessary requirements for the development of the audit tool; present a prototype and develop a tool ensuring the security requirements necessary for the maintenance of personal information, enabling its implementation, distribution and modification, and evaluating the impact of the tool for health auditing within the Brazilian Navy.Method: This is a descriptive, exploratory study with a qualitative approach applied to technological production, aimed at developing a mobile computerized tool to support the medical bill audit service. For development of the tool, Pressman's methodology was used, following the steps: collection and refinement of requirements, rapid design development, prototype construction, customer evaluation and further refinement when there is a need for final design adjustments, in order to satisfy the best way to meet the needs of customers. Results: 75 forms were distributed to the Navy auditors, with 65 (84.3%) answered, it was observed that 40.9% of respondents were nurses, 29.% had no experience in auditing. The speeches of the interviewees were analyzed emerging five categories related to improvements and one the criticism, respectively: expanding the module for cost control and forecasting; regulate the services that will be provided by the contractor; guide professionals to perform the health audit; expand module so that indicators and report can be presented; provide more information about the accredited and do not understand the purpose of the tool. Conclusion: It is believed that the tool will help auditors who have recently joined the Navy to perform the audit process according to the technique, generating uniformity, speeding up and, above all, avoiding losses for the organization. In this way, providing the professional with more skill and dexterity throughout the process

The reliability of maternal audit instruments to assign cause of death in maternal deaths review process: a systematic review and meta-analysis.

BACKGROUND: Maternal Death Reviews (MDR) can assist in formulating prevention strategies to reduce maternal mortality. To support MDR, an adequate MDR instrument is required to accurately identify the underlying causes of maternal deaths. We conducted a systematic review and meta-analysis to determine the reliability of maternal death instruments for conducting the MDR process. METHOD: Three databases: PubMed, ProQuest and EBSCO were systematically searched to identify related research articles published between January 2004 and July 2019. The review and meta-analysis involved identification of measurement tools to conduct MDR in all or part of maternal audit. Eligibiliy and quality of studies were evaluated using the Modified Quality Appraisal of Diagnostic Reliability (QAREL) Checklist: Reliability Studies. RESULTS: Overall, 242 articles were identified. Six articles examining the instrument used for MDR in 4 countries (4 articles on verbal autopsy (VA) and 2 articles on facility-based MDR) were included. None of studies identified reliability in evaluation instruments assessing maternal audit cycle as a comprehensive approach. The pooled kappa for the MDR instruments was 0.72 (95%CI:0.43-0.99; p < 0.001) with considerable heterogeneity (I2 = 96.19%; p < 0.001). Subgroup analysis of MDR instruments showed pooled kappa in VA of 0.89 (95%CI:0.52-1.25) and facility-based MDR of 0.48 (95%CI:0.15-0.82). Meta-regression analysis tended to show the high heterogeneity was likely associated with sample sizes, regions, and year of publications. CONCLUSIONS: The MDR instruments appear feasible. Variation of the instruments suggest the need for judicious selection of MDR instruments by considering the study population and assessment during the target periods.

Applications of liquid biopsy in the Pharmacological Audit Trail for anticancer drug development.

Anticancer drug development is a costly and protracted activity, and failure at late phases of clinical testing is common. We have previously proposed the Pharmacological Audit Trail (PhAT) intended to improve the efficiency of drug development, with a focus on the use of tumour tissue-based biomarkers. Blood-based 'liquid biopsy' approaches, such as targeted or whole-genome sequencing studies of plasma circulating cell-free tumour DNA (ctDNA) and circulating tumour cells (CTCs), are of increasing relevance to this drug development paradigm. Liquid biopsy assays can provide quantitative and qualitative data on prognostic, predictive, pharmacodynamic and clinical response biomarkers, and can also enable the characterization of disease evolution and resistance mechanisms. In this Perspective, we examine the promise of integrating liquid biopsy analyses into the PhAT, focusing on the current evidence, advances, limitations and challenges. We emphasize the continued importance of analytical validation and clinical qualification of circulating tumour biomarkers through prospective clinical trials.

Evaluating the appropriateness of platelet transfusions compared with evidence-based platelet guidelines: An audit of platelet transfusions at 57 hospitals.

BACKGROUND: Platelet transfusions are used to prevent or control bleeding in patients with thrombocytopenia or platelet dysfunction. The pretransfusion platelet count threshold has been studied extensively in multiple patient settings yielding high-quality evidence that has been summarized in several comprehensive evidence-based platelet guidelines. STUDY DESIGN AND METHODS: A prospective 12-week audit of consecutive platelet transfusions using validated and evidence-based adjudication criteria was conducted. Patient demographic, laboratory, and transfusion details were collected with an electronic audit tool. Each order was adjudicated either electronically or independently by two transfusion medicine physicians. The aim was to determine platelet transfusion appropriateness and common scenarios with deviations from guidelines. RESULTS: Fifty-seven (38%) of 150 hospitals provided data on 1903 platelet orders, representing 90% of platelet usage in the region during the time period. Overall, 702 of 1693 adult (41.5%) and 133 of 210 pediatric orders (63.3%) were deemed inappropriate. The most common inappropriate platelet order was for prophylaxis in the absence of bleeding or planned procedure in patients with hypoproliferative thrombocytopenia and a platelet count over 10 x 109 /L (53% of inappropriate orders in adults and 45% in pediatrics). Platelet transfusions ordered with either a preprinted transfusion order set (odds ratio [OR], 1.97; 95% confidence interval [CI], 1.44-2.73) or technologist prospective screening (OR, 1.40; 95% CI, 1.10-1.78) were more likely to be appropriate. CONCLUSION: There is a discrepancy between clinical practice and evidence-based platelet guidelines. Broad educational and system changes will be needed to align platelet transfusion practice with guideline recommendations.

Audit of Gastrointestinal Manifestations in Patients with Loeys-Dietz Syndrome and Vascular Ehlers-Danlos Syndrome.

OBJECTIVES: Loeys-Dietz syndrome (LDS) and vascular Ehlers-Danlos Syndrome (vEDS) are genetically heterogeneous heritable disorders of connective tissue. Both are multi-system disorders with dominant vascular pathology and associated gastrointestinal manifestations. AIM: To summarize the abdominal manifestations found in these two disorders in a cohort of patients seen at Mayo Clinic during a period of 25 years. METHODS: Data were collected via the advanced cohort explorer (ACE) of Mayo Clinic records from 1994 to 2018 in patients with vEDS or LDS confirmed by genetic testing and/or medical genetics consultation. We extracted information concerning gastrointestinal symptoms, abdominal hernias, and vascular manifestations or complications. RESULTS: We identified and reviewed records of 68 vEDS and 13 LDS patients. Patients were similar in age at diagnosis and gender distribution. Gastrointestinal symptoms were frequently reported in both disorders and largely similar, although altered bowel function was more prevalent in LDS patients. Hernias were present in similar proportions of patients with vEDS and LDS; however, ventral hernias were more frequent and more likely to be postoperative in vEDS than LDS. LDS patients had more arterial aneurysms overall (76.9% LDS vs. 58% vEDS, p = 0.02) and a higher proportion required arterial repair (69.2% LDS vs. 32.7% vEDS S, p = 0.03). Co-morbidities of autonomic dysfunction, psychopathology (most commonly anxiety, depression, adjustment disorder), and allergy were more prevalent in LDS than vEDS. CONCLUSION: Patients with vEDS and LDS had a propensity for gastrointestinal symptoms, abdominal hernias, and aneurysm formation, but repair for arterial rupture was more prevalent in LDS than EDS.

Epidemiology of trauma presentations to a major trauma centre in the North West of England during the COVID-19 level 4 lockdown.

PURPOSE: The COVID-19 pandemic has impacted healthcare systems globally, little is known about the trauma patterns during a national lockdown. The aim of this study is to delineate the trauma patterns and outcomes at Aintree University Teaching Hospital level 1 Major Trauma Centre (MTC) during the COVID-19 lockdown imposed by the U.K. government. METHODS: A retrospective cohort study data from the Merseyside and Cheshire Trauma Audit and Research Network database were analysed. The 7-week 'lockdown period' was compared to a 7-week period prior to the lockdown and also to an equivalent 7-week period corresponding to the previous year. RESULTS: A total of 488 patients were included in the study. Overall, there was 37.6% and 30.0% reduction in the number of traumatic injuries during lockdown. Road traffic collisions (RTC) reduced by 42.6% and 46.6%. RTC involving a car significantly reduced during lockdown, conversely, bike-related RTC significantly increased. No significant changes were noted in deliberate self-harm, trauma severity and crude mortality during lockdown. There was 1 mortality from COVID-19 infection in the lockdown cohort. CONCLUSION: Trauma continues during lockdown, our MTC has continued to provide a full service during lockdown. However, trauma patterns have changed and departments should adapt to balance these alongside the COVID-19 pandemic. As the U.K. starts its cautious transition out of lockdown, trauma services are required to be flexible during changes in national social restrictions and changing trauma patterns. COVID-19 and lockdown state were found to have no significant impact on survival outcomes for trauma.

Admission avoidance in tonsillitis and peritonsillar abscess: A prospective national audit during the initial peak of the COVID-19 pandemic.

OBJECTIVES: To report changes in practice brought about by COVID-19 and the implementation of new guidelines for the management of tonsillitis and peritonsillar abscess (PTA), and to explore factors relating to unscheduled re-presentations for patients discharged from the emergency department (ED). DESIGN: Prospective multicentre national audit over 12 weeks from 6 April 2020. SETTING: UK secondary care ENT departments. PARTICIPANTS: Adult patients with acute tonsillitis or PTA. MAIN OUTCOME MEASURES: Re-presentation within 10 days for patients discharged from the ED. RESULTS: 83 centres submitted 765 tonsillitis and 416 PTA cases. 54.4% (n = 410) of tonsillitis and 45.3% (187/413) of PTAs were discharged from ED. 9.6% (39/408) of tonsillitis and 10.3% (19/184) of PTA discharges re-presented within 10 days, compared to 9.7% (33/341) and 10.6% (24/224) for those admitted from ED. The subsequent admission rate of those initially discharged from ED was 4.7% for tonsillitis and 3.3% for PTAs. IV steroids and antibiotics increased the percentage of patients able to swallow from 35.8% to 72.5% for tonsillitis (n = 270/754 and 441/608) and from 22.3% to 71.0% for PTA (n = 92/413 and 265/373). 77.2% of PTAs underwent drainage (n = 319/413), with no significant difference in re-presentations in those drained vs not-drained (10.6% vs 9.5%, n = 15/142 vs 4/42, P = .846). Univariable logistic regression showed no significant predictors of re-presentation within 10 days. CONCLUSIONS: Management of tonsillitis and PTA changed during the initial peak of the pandemic, shifting towards outpatient care. Some patients who may previously have been admitted to hospital may be safely discharged from the ED.

Clinical audit as an educative tool for optometrists: an intervention study in age-related macular degeneration.

PURPOSE: Age-related macular degeneration (AMD) is a major cause of vision loss. This study investigated whether performing clinical audit and receiving analytical performance feedback altered documentation of the AMD care provided by optometrists. METHODS: Australian optometrists were recruited and completed a survey about their demographics and confidence in AMD care, and a three-month audit of their practice records using an AMD audit tool (termed the pre-audit evaluation). After receiving analytical feedback, participants identified areas for improvement and re-audited their practices after three months to analyse changes in performance (termed the post-audit evaluation). Paired t-tests and Wilcoxon signed-rank tests, as appropriate, were used to compare pre- and post-audit data. RESULTS: Twenty optometrists, most practising in Victoria, Australia, completed the study. Participants primarily worked in corporate practice and/or rural settings and had a range of optometric experience (2-40 years). At baseline, participants felt confident in their: knowledge of AMD risk factors (65%), advice to patients about these factors (55%) and management of earlier stages of AMD (55%). Each clinician completed (median [IQR]): 15 [IQR: 10-19] and 12 [IQR: 8-16] audits of unique patient records, pre- and post-audit, respectively. Post-audit, average record documentation (per optometrist) improved for asking about: AMD family history (94% to 100%, p = 0.03), smoking status (21% to 58%, p < 0.01), diet (11% to 29%, p < 0.01) and nutritional supplementation (20% to 51%, p < 0.01). For clinical examination, compliance with documenting pinhole visual acuity, performing an in-office Amsler grid (upon indication) and using optical coherence tomography improved post-audit (p < 0.05). Accuracy of severity documentation improved for earlier stages of AMD (p < 0.05). For earlier stages of AMD, documentation of counselling about modifiable risk factors significantly improved post-audit (p < 0.05). Aspects well-performed pre-audit that did not change included documenting: medical histories (100% at both time points, p = 0.06) and retinal imaging (77% at both time points, p = 0.97). CONCLUSIONS: Self-audit with analytical feedback improved clinical record documentation of: AMD risk factors, clinical examination, AMD severity classification and management advice. These findings support a role for audit to improve optometric clinical care of AMD, as evidenced by improved documentation of the AMD care delivered.

Chart Audit of Spiritual Care Documentation: Continuous Quality Improvement.

Eight spiritual care practitioners at an acute care teaching hospital undertook a systematic chart audit of their documentation practices in the patient electronic health record. The purpose was to evaluate their practices using the standards of their professional association and regulatory college. A preliminary "mock audit" was essential for the overall success of the audit. Plans for ongoing chart audits will lead to continuous quality improvement. A limitation was that their manager acted as both improvement coach and performance evaluator.

Finding the match between healthcare worker and expert for optimal audit and feedback on antimicrobial resistance prevention measures.

BACKGROUND: The potentials of audit and feedback (AF) to improve healthcare are currently not exploited. To unlock the potentials of AF, this study focused on the process of making sense of audit data and translating data into actionable feedback by studying a specific AF-case: limiting antimicrobial resistance (AMR). This was done via audit and feedback of AMR prevention measures (APM) that are executed by healthcare workers (HCW) in their day-to-day contact with patients. This study's aim was to counterbalance the current predominantly top-down, expert-driven audit and feedback approach for APM, with needs and expectations of HCW. METHODS: Qualitative semi-structured interviews were held with sixteen HCW (i.e. physicians, residents and nurses) from high-risk AMR departments at a regional hospital in The Netherlands. Deductive coding was succeeded by open and axial coding to establish main codes, subcodes and variations within codes. RESULTS: HCW demand insights from audits into all facets of APM in their working routines (i.e. diagnostics, treatment and infection control), preferably in the form of simple and actionable feedback that invites interdisciplinary discussions, so that substantiated actions for improvement can be implemented. AF should not be seen as an isolated ad-hoc intervention, but as a recurrent, long-term, and organic improvement strategy that balances the primary aims of HCW (i.e. improving quality and safety of care for individual patients and HCW) and AMR-experts (i.e. reducing the burden of AMR). CONCLUSIONS: To unlock the learning and improvement potentials of audit and feedback, HCW' and AMR-experts' perspectives should be balanced throughout the whole AF-loop (incl. data collection, analysis, visualization, feedback and planning, implementing and monitoring actions). APM-AF should be flexible, so that both audit (incl. collecting and combining the right data in an efficient and transparent manner) and feedback (incl. persuasive and actionable feedback) can be tailored to the needs of various target groups. To balance HCW' and AMR-experts' perspectives a participatory holistic AF development approach is advocated.

Improved detection of adenomas and sessile serrated polyps is maintained with continuous audit of colonoscopy.

BACKGROUND: The audit process may help improve performance indicators for colonoscopy quality but it is unclear whether this is sustained over several years. METHODS: 44138 procedures for 28 endoscopists from 2004 to 2019 were analysed for polyp detection rate and withdrawal time. From 2012, 14 endoscopists were analysed with additional data on polyp histology and number of polyps removed. RESULTS: Polyp detection increased from 40.7% in 2004 to 62.2% in 2019; removal of polyps>1 cm remained constant (11%). Adenoma detection rate was 25.8% in 2012 and 28.3% in 2019. Sessile serrated polyp (SSP) detection rate increased from 4.5% to 14.7%; most of the increase was in the first 2 years of the histology part of the audit. There was a significant correlation of adenoma detection rate with mean number of adenomas (r=0.72, p=0.004) and a significant correlation of SSP detection with mean number of SSPs (r=0.85, p=0.0001). CONCLUSION: The audit process appears to encourage a higher rate of polyp detection. This was due to increased detection of smaller polyps and increased detection of SSPs.

Clinical audit of gentamicin use by Bayesian pharmacokinetic approach in critically ill children.

INTRODUCTION: Critically ill children tend to have altered gentamicin pharmacokinetics (PK); and so we carried out an audit of gentamicin use using the estimated peak concentrations (Cmax), trough concentrations (Cmin) and area-under-the-concentration-time curve (AUCs) by Bayesian approach. METHODS: Critically ill children with at least one serum gentamicin concentrations available were recruited. We used multiple models Bayesian adaptive control to estimate Cmax, and AUC0-t following each dose. Pediatric risk, injury, failure, loss, end stage renal disease (pRIFLE) criteria was used to identify the incidence of acute kidney injury (AKI). RESULTS: Seventy-three children (961 doses and 143 concentrations) were analysed. AUC0-24 was observed to be higher in earlier age groups with a steady decline in older children. Similar changes were observed in Cmax, Cmin and AUC0-24 at steady state. Significantly higher proportions of children in the other age groups were estimated to have Cmax between 5 and 10 mg/L compared to neonates. Neonates had a higher risk of Cmax above 10 mg/L. Patients with augmented renal clearance exhibited lower AUC0-24 and reduced proportion achieving the target AUC0-24 levels. Nearly one-third of children were observed to meet the pRIFLE criteria for AKI. CONCLUSION: We observed higher initial doses and peak concentrations of gentamicin in neonates and infants compared to older age groups in critically ill children. Uniformity in the paediatric-specific standard treatment guidelines for gentamicin is the need of the hour.

Use of inhaled devices during a hospital exacerbation of COPD: a summary of an interdisciplinary audit held at ICS Maugeri Pavia, Italy (March-June 2019).

To date treatment protocols in Respiratory and or Internal departments across Italy for treatment of chronic obstructive pulmonary disease (COPD) patients at hospital admission with relapse due to exacerbation do not find adequate support in current guidelines. Here we describe the results of a recent clinical audit, including a systematic review of practices reported in literature and an open discussion comparing these to current real-life procedures. The process was dived into two 8-hour-audits 3 months apart in order to allow work on the field in between meeting and involved 13 participants (3 nurses, 1 physiotherapist, 2 internists and 7 pulmonologists). This document reports the opinions of the experts and their consensus, leading to a bundle of multidisciplinary statements on the use of inhaled drugs for hospitalized COPD patients. Recommendations and topics addressed include: i) monitoring and diagnosis during the first 24 h after admission; ii) treatment algorithm and options (i.e., short and long acting bronchodilators); iii) bronchodilator dosages when switching device or using spacer; iv) flow measurement systems for shifting to LABA+LAMA within 48 h; v) when nebulizers are recommended; vi) use of SMI to deliver LABA+LAMA when patient needs SABA <3 times/day independently from flow limitation; vii) use of DPI and pre-dosed MDI to deliver LABA+LAMA or TRIPLE when patient needs SABA <3 times/day, with inspiratory flow > 30 litres/min; viii) contraindication to use DPI; ix) continuation of LABA-LAMA when patient is already on therapy; x) possible LABA-LAMA dosage increase; xi) use of SABA and/or SAMA in addition to LABA+LABA; xii) use of SABA+SAMA restricted to real need; xiii) reconciliation of drugs in presence of comorbidities; xiv) check of knowledge and skills on inhalation therapy; xv) discharge bundle; xvi) use of MDI and SMI in tracheostomized patients in spontaneous and ventilated breathing.

Heterogeneity of clinical management of low-grade gastric lymphoma of mucosa-associated lymphoid tissue. An audit of 198 patients in Spain / Heterogeneidad en el tratamiento clínico del linfoma gástrico de tejido linfoide asociado a mucosas de bajo grado. Una auditoría de 198 pacientes en España

Introduction: Cure of Helicobacter pylori infection in patients with gastric lymphoma of mucosa-associated lymphoid tissue (MALT) leads to long-term clinical remission in the initial stages. As it is a rare disease, its management in clinical practice remains largely unknown and heterogeneity of care remains a concern. The aim was to audit the management and evolution of a large series of low-grade gastric MALT lymphomas from thirteen Spanish hospitals. Materials and methods: Multicentre retrospective study including data on the diagnosis and follow-up of patients with gastric low-grade MALT lymphoma from January 1998 to December 2013. Clinical, biological and pathological data were analyzed and survival curves were drawn. Results: One-hundred and ninety-eight patients were included. Helicobacter pylori was present in 132 (69%) patients and 103 (82%) in tumors confined to the stomach (stage EI) and was eradicated in 92% of patients. Chemotherapy was given in 90 (45%) patients and 43 (33%) with stage EI. Marked heterogeneity in the use of diagnostic methods and chemotherapy was observed. Five-year overall survival was 86% (89% in EI). Survival was similar in EI patients receiving aggressive treatment and in those receiving only antibiotics (p=0.577). Discussion: Gastric MALT lymphoma has an excellent prognosis. We observed, however, a marked heterogeneity in the use of diagnostic methods or chemotherapy in early-stage patients

Introducción: La cura de la infección por Helicobacter pylori (H. pylori) en pacientes con linfoma gástrico de tejido linfoide asociado mucosas (mucosa-associated lymphoid tissue [MALT]) conduce a la remisión clínica a largo plazo en los estadios iniciales. Al tratarse de una enfermedad rara, su tratamiento en la práctica clínica en muchas ocasiones se desconoce y la heterogeneidad de la atención sigue siendo motivo de preocupación. El objetivo es auditar el tratamiento y la evolución de una gran serie de linfomas gástricos MALT de bajo grado procedentes de 13 hospitales españoles. Materiales y métodos: Estudio retrospectivo y multicéntrico que incluye datos sobre el diagnóstico y el seguimiento de pacientes con linfoma MALT gástrico de bajo grado desde enero de 1998 hasta diciembre del 2013. Se analizaron los datos clínicos, biológicos y patológicos, y se trazaron las curvas de supervivencia. Resultados: Se incluyó a 198 pacientes. El H. pylori estaba presente en 132 (69%) de los pacientes y en 103 (82%) tumores confinados al estómago (estadio EI) y se erradicó en el 92% de los pacientes. Se administró quimioterapia a 90 (45%) de los pacientes y a 43 (33%) en estadio EI. Se observó una marcada heterogeneidad en el uso de los métodos de diagnóstico y de la quimioterapia. La supervivencia global a los 5 años fue del 86% (89% en estadio EI). La supervivencia fue similar en los pacientes en estadio EI que recibieron tratamiento agresivo y en los que recibieron solo antibióticos (p=0,577). Discusión: El linfoma MALT gástrico presenta un pronóstico excelente. Sin embargo, se observó una marcada heterogeneidad en el uso de los métodos de diagnóstico o la quimioterapia en pacientes en estadio inicial

Clinical guided computer tomography decisions are advocated in potentially severely injured trauma patients: a one-year audit in a level 1 trauma Centre with long pre-hospital times.

BACKGROUND: The International Commission on Radiological Protection's (ICRP) justification principles state that an examination is justified if the potential benefit outweighs the risk for radiation harm. Computer tomography (CT) contributes 50% of the radiation dose from medical imaging, and in trauma patients, the use of standardized whole body CT (SWBCT) increases. Guidelines are lacking, and reviews conclude conflictingly regarding the benefit. We aimed to study the degree of adherence to ICRP's level three justification, the individual dose limitation principle, in our institution. METHODS: This is a retrospective clinical audit. We included all 144 patients admitted with trauma team activation to our regional Level 1 trauma centre in 2015. Injuries were categorized according to the Abbreviated Injury Scale (AIS) codes. Time variables, vital parameters and interventions were registered. We categorized patients into trauma admission SWBCT, selective CT or no CT examination strategy groups. We used descriptive statistics and regression analysis of predictors for CT examination strategy. RESULTS: The 144 patients (114 (79.2%) males) had a median age of 31 (range 0-91) years. 105 (72.9%) had at least one AIS ≥ 2 injury, 26 (18.1%) in more than two body regions. During trauma admission, at least one vital parameter was abnormal in 46 (32.4%) patients, and 73 (50.7%) underwent SWBCT, 43 (29.9%) selective CT and 28 (19.4%) no CT examination. No or only minor injuries were identified in 17 (23.3%) in the SWBCT group. Two (4.6%) in the selective group were examined with a complement CT, with no new injuries identified. A significantly (p < 0.001) lower proportion of children (61.5%) than adults (89.8%) underwent CT examination despite similar injury grades and use of interventions. In adjusted regression analysis, patients with a high-energy trauma mechanism had significantly (p = 0.028) increased odds (odds ratio = 4.390, 95% confidence interval 1.174-16.413) for undergoing a SWBCT. CONCLUSION: The high proportion of patients with no or only minor injuries detected in the SWBCT group and the significantly lower use of CT among children, indicate that use of a selective CT examination strategy in a higher proportion of our patients would have approximated the ICRP's justification level three, the individual dose limitation principle, better.

Large-scale empirical optimisation of statistical control charts to detect clinically relevant increases in surgical site infection rates.

OBJECTIVE: Surgical site infections (SSIs) are common costly hospital-acquired conditions. While statistical process control (SPC) use in healthcare has increased, limited rigorous empirical research compares and optimises these methods for SSI surveillance. We sought to determine which SPC chart types and design parameters maximise the detection of clinically relevant SSI rate increases while minimising false alarms. DESIGN: Systematic retrospective data analysis and empirical optimisation. METHODS: We analysed 12 years of data on 13 surgical procedures from a network of 58 community hospitals. Statistically significant SSI rate increases (signals) at individual hospitals initially were identified using 50 different SPC chart variations (Shewhart or exponentially weighted moving average, 5 baseline periods, 5 baseline types). Blinded epidemiologists evaluated the clinical significance of 2709 representative signals of potential outbreaks (out of 5536 generated), rating them as requiring 'action' or 'no action'. These ratings were used to identify which SPC approaches maximised sensitivity and specificity within a broader set of 3600 individual chart variations (additional baseline variations and chart types, including moving average (MA), and five control limit widths) and over 32 million dual-chart combinations based on different baseline periods, reference data (network-wide vs local hospital SSI rates), control limit widths and other calculation considerations. Results were validated with an additional year of data from the same hospital cohort. RESULTS: The optimal SPC approach to detect clinically important SSI rate increases used two simultaneous MA charts calculated using lagged rolling baseline windows and 1 SD limits. The first chart used 12-month MAs with 18-month baselines and best identified small sustained increases above network-wide SSI rates. The second chart used 6-month MAs with 3-month baselines and best detected large short-term increases above individual hospital SSI rates. This combination outperformed more commonly used charts, with high sensitivity (0.90; positive predictive value=0.56) and practical specificity (0.67; negative predictive value=0.94). CONCLUSIONS: An optimised combination of two MA charts had the best performance for identifying clinically relevant small but sustained above-network SSI rates and large short-term individual hospital increases.

Reducing caesarean delivery: An economic evaluation of routine induction of labour at 39 weeks in low-risk nulliparous women.

BACKGROUND: Clinical interventions known to reduce the risk of caesarean delivery include routine induction of labour at 39 weeks, caseload midwifery and chart audit, but they have not been compared for cost-effectiveness. OBJECTIVE: To assesses the cost-effectiveness of three different interventions known to reduce caesarean delivery rates compared to standard care; and conduct a budget impact analysis. METHODS: A Markov microsimulation model was constructed to compare the costs and outcomes produced by the different interventions. Costs included all costs to the health system, and outcomes were quality-adjusted life years (QALY) gained. A budget impact analysis was undertaken using this model to quantify the costs (in Australian dollars) over three years for government health system funders. RESULTS: All interventions, plus standard care, produced similar health outcomes (mean of 1.84 QALYs gained over 105 weeks). Caseload midwifery was the lowest cost option at $15 587 (95% confidence interval [CI] 15 269, 15 905), followed by routine induction of labour ($16 257, 95% CI 15 989, 16 536), and chart audit ($16 325, 95% CI 15 979, 16 671). All produced lower costs on average than standard care ($16 905, 95% CI 16 551, 17 259). Caseload midwifery would produce the greatest savings of $172.6 million over three years if implemented for all low-risk nulliparous women in Australia. CONCLUSIONS: Caseload midwifery presents the best value for reducing caesarean delivery rates of the options considered. Routine induction of labour at 39 weeks and chart audit would also reduce costs compared to standard care.
