RESUMEN
OBJECTIVES: The PREDICT study aimed to determine how the COVID-19 pandemic affected surgical services and surgical patients and to identify predictors of outcomes in this cohort. BACKGROUND: High mortality rates were reported for surgical patients with COVID-19 in the early stages of the pandemic. However, the indirect impact of the pandemic on this cohort is not understood, and risk predictors are yet to be identified. METHODS: PREDICT is an international longitudinal cohort study comprising surgical patients presenting to hospital between March and August 2020, conducted alongside a survey of staff redeployment and departmental restructuring. A subgroup analysis of 3176 adult emergency patients, recruited by 55 teams across 18 countries is presented. RESULTS: Among adult emergency surgical patients, all-cause in-hospital mortality (IHM) was 3.6%, compared to 15.5% for those with COVID-19. However, only 14.1% received a COVID-19 test on admission in March, increasing to 76.5% by July.Higher Clinical Frailty Scale scores (CFS >7 aOR 18.87), ASA grade above 2 (aOR 4.29), and COVID-19 infection (aOR 5.12) were independently associated with significantly increased IHM.The peak months of the first wave were independently associated with significantly higher IHM (March aOR 4.34; April aOR 4.25; May aOR 3.97), compared to non-peak months.During the study, UK operating theatre capacity decreased by a mean of 63.6% with a concomitant 27.3% reduction in surgical staffing. CONCLUSION: The first wave of the COVID-19 pandemic significantly impacted surgical patients, both directly through co-morbid infection and indirectly as shown by increasing mortality in peak months, irrespective of COVID-19 status.Higher CFS scores and ASA grades strongly predict outcomes in surgical patients and are an important risk assessment tool during the pandemic.

BACKGROUND: Enabling patients to be active users of their own medical records may promote the delivery of safe, efficient care across settings. Patients are rarely involved in designing digital health record systems which may make them unsuitable for patient use. We aimed to develop an evidence-based electronic health record (EHR) interface and participatory design process by involving patients and the public. METHODS: Participants were recruited to multi-step workshops involving individual and group design activities. A mixture of quantitative and qualitative questionnaires and observational methods were used to collect participant perspectives on interface design and feedback on the workshop design process. RESULTS: 48 recruited participants identified several design principles and components of a patient-centred electronic medical record interface. Most participants indicated that an interactive timeline would be an appropriate way to depict a medical history. Several key principles and design components, including the use of specific colours and shapes for clinical events, were identified. Participants found the workshop design process utilised to be useful, interesting, enjoyable and beneficial to their understanding of the challenges of information exchange in healthcare. CONCLUSION: Patients and the public should be involved in EHR interface design if these systems are to be suitable for use by patient-users. Workshops, as used in this study, can provide an engaging format for patient design input. Design principles and components highlighted in this study should be considered when patient-facing EHR design interfaces are being developed.

Abscess formation of the falciform ligament is incredibly rare and perplexing when encountered for the first time. It is reported to occur in the setting of cholecystitis and cholangitis, but the pathophysiology is poorly understood.In this case report, we present a 73-year-old man with falciform ligament abscess following cholangitis from an obstructive ampullary carcinoma. The patient was referred to the Royal Adelaide Hospital from a country hospital, with progressive jaundice, anorexia and nausea. Prior to transfer, he deteriorated with cholangitis, dehydration and renal failure. On arrival, his abdomen was exquisitely tender along the course of the falciform ligament. His blood tests revealed an elevated white cell count of 14.9 x 10(3)/µl, bilirubin of 291 µmol/l and creatinine of 347 µmol/l. His CA 19-9 was markedly elevated at 35,000 kU/l. A non-contrast computed tomography (CT) demonstrated gross biliary dilatation and a collection tracking along the path of the falciform ligament to the umbilicus. The patient was commenced on intravenous antibiotics and underwent an urgent endoscopic retrograde cholangiopancreatogram (ERCP) with sphincterotomy and biliary stent drainage. Cholangiogram revealed a grossly dilated biliary tree, with abrupt transition at the ampulla, which on biopsy confirmed an obstructing ampullary carcinoma. Following ERCP, his jaundice and abdominal tenderness resolved. He was optimized over 4 weeks for an elective pancreaticoduodenectomy. At operation, we found abscess transformation of the falciform ligament. Copious amounts of pus and necrotic material was drained. Part of the round ligament was resected along the undersurface of the liver. Histology showed that there was prominent histiocytic inflammation with granular acellular eosinophilic components. The patient recovered slowly but uneventfully. A contrast CT scan undertaken 2 weeks post-operatively (approximately 7 weeks after the initial CT) revealed left portal venous thrombosis, which was likely to be a delayed discovery and was managed conservatively. We present this patient's operative images and radiographic findings, which may explain the pathophysiology behind this rare complication. We hypothesize that cholangitis, with secondary portal pyaemia and tracking via the paraumbilical veins, can cause infectious seeding of the falciform ligament, with consequent abscess formation.

OBJECTIVES: To determine the frequency of use and spatial distribution of health record systems in the English National Health Service (NHS). To quantify transitions of care between acute hospital trusts and health record systems to guide improvements to data sharing and interoperability. DESIGN: Retrospective observational study using Hospital Episode Statistics. SETTING: Acute hospital trusts in the NHS in England. PARTICIPANTS: All adult patients resident in England that had one or more inpatient, outpatient or accident and emergency encounters at acute NHS hospital trusts between April 2017 and April 2018. PRIMARY AND SECONDARY OUTCOME MEASURES: Frequency of use and spatial distribution of health record systems. Frequency and spatial distribution of transitions of care between hospital trusts and health record systems. RESULTS: 21 286 873 patients were involved in 121 351 837 encounters at 152 included trusts. 117 (77.0%) hospital trusts were using electronic health records (EHR). There was limited regional alignment of EHR systems. On 11 017 767 (9.1%) occasions, patients attended a hospital using a different health record system to their previous hospital attendance. 15 736 863 (73.9%) patients had two or more encounters with the included trusts and 3 931 255 (25.0%) of those attended two or more trusts. Over half (53.6%) of these patients had encounters shared between just 20 pairs of hospitals. Only two of these pairs of trusts used the same EHR system. CONCLUSIONS: Each year, millions of patients in England attend two or more different hospital trusts. Most of the pairs of trusts that commonly share patients do not use the same record systems. This research highlights significant barriers to inter-hospital data sharing and interoperability. Findings from this study can be used to improve electronic health record system coordination and develop targeted approaches to improve interoperability. The methods used in this study could be used in other healthcare systems that face the same interoperability challenges.

BACKGROUND: Inflammatory bowel disease (IBD) is a chronic, inflammatory disorder characterised by both intestinal and extra-intestinal pathology. Patients may receive both emergency and elective care from several providers, often in different hospital settings. Poorly managed transitions of care between providers can lead to inefficiencies in care and patient safety issues. To ensure that the sharing of patient information between providers is appropriate, timely, accurate and secure, effective data-sharing infrastructure needs to be developed. To optimise inter-hospital data-sharing for IBD patients, we need to better understand patterns of hospital encounters in this group. AIM: To determine the type and location of hospital services accessed by IBD patients in England. METHODS: This was a retrospective observational study using Hospital Episode Statistics, a large administrative patient data set from the National Health Service in England. Adult patients with a diagnosis of IBD following admission to hospital were followed over a 2-year period to determine the proportion of care accessed at the same hospital providing their outpatient IBD care, defined as their 'home provider'. Secondary outcome measures included the geographic distribution of patient-sharing, regional and age-related differences in accessing services, and type and frequency of outpatient encounters. RESULTS: 95055 patients accessed hospital services on 1760156 occasions over a 2-year follow-up period. The proportion of these encounters with their identified IBD 'home provider' was 73.3%, 87.8% and 83.1% for accident and emergency, inpatient and outpatient encounters respectively. Patients living in metropolitan centres and younger patients were less likely to attend their 'home provider' for hospital services. The most commonly attended specialty services were gastroenterology, general surgery and ophthalmology. CONCLUSION: Transitions of care between secondary care settings are common for patients with IBD. Effective systems of data-sharing and care integration are essential to providing safe and effective care for patients. Geographic and age-related patterns of care transitions identified in this study may be used to guide interventions aimed at improving continuity of care.

A 27-year-old man presented to a major trauma centre with two posterolateral thoracic stab injuries over the right scapula and thoracoabdominal junction. He was tachycardic and hypotensive with a chest X-ray revealing a large right-sided tension haemothorax, requiring insertion of two intercostal chest drains. A subsequent CT scan demonstrated a grade 4 right kidney laceration with active back bleeding from a renal artery branch, through a right diaphragmatic defect, into the pleural cavity. Embolisation of the feeding renal vessel controlled the bleeding and avoided the need for a nephrectomy. The patient required subsequent video-assisted thoracoscopic evacuation of the haemothorax and diaphragmatic repair, confirming that there was no associated lung or major vessel injury. A ureteric stent was ultimately inserted to manage a persistent urinary leak. This case highlights a rare cause for a common traumatic presentation and the need for a multidisciplinary approach in effective management of complex, multiorgan trauma.

Effective sharing of clinical information between care providers is a critical component of a safe, efficient health system. National data-sharing systems may be costly, politically contentious and do not reflect local patterns of care delivery. This study examines hospital attendances in England from 2013 to 2015 to identify instances of patient sharing between hospitals. Of 19.6 million patients receiving care from 155 hospital care providers, 130 million presentations were identified. On 14.7 million occasions (12%), patients attended a different hospital to the one they attended on their previous interaction. A network of hospitals was constructed based on the frequency of patient sharing between hospitals which was partitioned using the Louvain algorithm into ten distinct data-sharing communities, improving the continuity of data sharing in such instances from 0 to 65-95%. Locally implemented data-sharing communities of hospitals may achieve effective accessibility of clinical information without a large-scale national interoperable information system.
RESUMEN
BACKGROUND: The aim of this study was to determine if wearing a bicycle helmet during ladder use could reduce the incidence and severity of head injury in the event of a fall. METHODS: A headform model with inbuilt accelerometers was used to determine the Head Injury Criterion (HIC) score of head impact by dropping 41 helmeted and unhelmeted headforms from eight heights. These results were compared. RESULTS: There was a statistically significant difference between averaged HIC scores in helmeted and unhelmeted drops (P < 0.001). Unhelmeted HIC scores ranged from 387 at 0.25 m to 2121 at 0.6 m. Helmeted HIC scores ranged from 29 at 0.25 m to 1199 at 2.5 m. At a height of 0.5 m, the risk of severe brain injury (AIS ≥4) from direct frontal head impact is predicted to reduce from >50% to <5% with helmet use. CONCLUSION: There was a significant decrease in the HIC scores when helmets are used and it is likely that the benefits would be seen in the clinical setting. These results provide an argument for the use of a bicycle helmets by all ladder users, in particular those over age 50 who are at increased risk of head injuries. We recommend that bicycle helmet use be incorporated into ladder injury prevention strategies.

AIMS: To investigate and assess variation in routine approaches to the handling of basal cell carcinoma (BCC) re-excision specimens by Australian histopathologists. METHODS: A questionnaire was sent to 440 Australian histopathologists requesting details of their routine approach to the handling of BCC re-excision specimens. Responses were collated and compared to demonstrate any variation in approach. RESULTS: Responses received from 208 pathologists indicated that variation was present in most aspects of specimen handling, including cut-up, examination of the specimen and reporting. CONCLUSIONS: Variation demonstrated in the routine handling of BCC re-excision specimens may have important academic and clinical implications. It is important for pathologists to communicate their specimen handling approach to the surgeon. Further study should be conducted to specifically compare the various specimen handling approaches that were identified in this study. The development of evidence-based guidelines for the routine handling of BCC re-excision specimens may be appropriate.

BACKGROUND: Serum carcinoembryonic antigen (CEA) levels are not universally measured in colorectal cancers. CEA levels have been reported to be usually normal at time of primary rectal cancer diagnosis but elevated in recurrent disease. The aims of the study were to (1) compare serum CEA levels performed at time of primary and recurrent colorectal tumour diagnosis; and (2) to determine serum CEA levels in rectal cancers at primary diagnosis to analyse potential factors influencing differing CEA levels. METHODS: A retrospective analysis of patients treated for colorectal cancers at Modbury Hospital, South Australia was performed. Each admission was reviewed within the electronic database. Serum CEA levels and tumour-related factors were determined in patients who underwent curative surgery for their primary tumour and developed tumour recurrence/metastases within the study period. RESULTS: 438 patients were treated for colorectal cancer in the study period. In patients who underwent curative surgery and developed a recurrence, serum CEA was elevated in 20% patients at primary diagnosis and in 46.6% patients at recurrence. Only 1 of 30 patients with rectal cancer had an elevated CEA at diagnosis of primary tumour. Tumour relationship to the peritoneal reflection did not appear to play a role. CONCLUSIONS: In rectal cancers, serum CEA levels are often normal at the time of initial diagnosis. However, this should not preclude its use in post-operative surveillance. Serum CEA levels noted in primary rectal cancer appear unrelated to the relationship of the tumour to the peritoneal reflection. Stroma-related factors could possibly be involved and merit further investigation.
