Validity of algorithms for identifying mild traumatic brain injury in the French national emergency department database OSCOUR: a retrospective multicentre validation study protocol.

INTRODUCTION: The French emergency department (ED) surveillance network OSCOUR transmits data on ED visits to Santé publique France (the national public health agency). As these data are collected daily and are almost exhaustive at a national level, it would seem relevant to use them for national epidemiological surveillance of mild traumatic brain injury (mTBI). This article presents the protocol of a planned study to validate algorithms for identifying mTBI in the OSCOUR database. Algorithms to be tested will be based on International Classification of Diseases (ICD)-10 codes. METHODS AND ANALYSIS: We will perform a multicentre validation study of algorithms for identifying mTBI in OSCOUR. Different combinations of ICD-10 codes will be used to identify cases of mTBI in the OSCOUR database. A random sample of mTBI cases and non-cases will be selected from four EDs. Medical charts will serve as the reference standard to validate the algorithms. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the different algorithms, as well as their 95% CIs, will be calculated and compared. ETHICS AND DISSEMINATION: The ethics committee of the French National Data Protection Authority (CNIL) approved this study (n° 921152, 1 August 2021). Results will be submitted to national and international peer-reviewed journals and presented at conferences dedicated to trauma and to methodologies for the construction and validation of algorithms.

Quality of pain management in the emergency department: results of a multicentre prospective study.

OBJECTIVES: The purpose of this study was to evaluate pain management in a large sample of emergency departments (EDs) and identify potential corrective measures. METHOLOGY: A multicentre prospective study was performed in 50 EDs participating in a national quality improvement programme. The rate of inclusion was determined a priori in each ED. Patients were questioned about their pain and pain intensity was assessed by a visual analogue scale. A bivariate and a multivariate analysis were conducted to identify the criteria associated with inadequate pain management. RESULTS: A total of 11 670 patients were included and 7265 patients reported pain on admission. On arrival, pain intensity was assessed in 90% of patients (44% experienced severe pain). However, reassessments were performed less often (48% on discharge). Fifty-one percent of patients received pain treatment. Intravenous morphine was used in only 9% of patients with severe pain. Initial treatment was provided within 60 min of admission to 74% of patients. Among patients who were assessed on discharge, 27% still had pain (8% with severe pain). Delay for pain management was significantly related to the ED volume, lack of triage nurses, patients' disorders and initial pain intensity. CONCLUSION: This multicentre study conducted on a nationwide scale shows that pain relief can be improved in the ED. Pain intensity is not sufficiently reassessed, analgesics are underutilised, morphine sulfate is rarely used and delay in treatment is common. Reasons for inadequate analgesia were identified in order to identify relevant corrective measures to improve quality of pain management in the ED.

Twelve-year outcomes after endovascular aneurysm repair using earliest available endograft components from a single center.

OBJECTIVES: Comprehensive long-term outcome data after endovascular aneurysm repair (EVAR) are scarce, although anecdotes of endograft failure in the early 1990s abound. The objective of this report is to provide comprehensive outcomes after EVAR performed with the earliest available endograft components. These were a home-made endograft (pre-expanded polytetrafluoroethylene [PTFE] fixed with giant Palmaz stents) and first-generation Talent endografts (World Medical, Sunrise, Fla). METHODS: A prospectively recorded database of all cases undertaken at a tertiary referral center was retrospectively interrogated. Sex, age, types of endograft used, and fate of patient and endografts implanted between 10 and 15 years previously were studied. A literature search was undertaken to obtain data for long-term survival after EVAR and open surgery (OR). RESULTS: There were 50 patients in total operated on between 1994 and 1998 of whom 43 were male. The median age was 73 years (54-93) at time of EVAR and 85 years (67-100) in the survivors at a median of 12 years later. There were 26 home-made (PTFE fixed with Palmaz stents) and 24 Talent endografts (World Medical). Thirty-day mortality was 4%, one death in a ruptured abdominal aortic aneurysm. Twenty-one (42%) survived for 12 years to the time of reporting. Of these, 6 have functioning home-made endografts, 8 have Talent endografts, and 8 (5 home-made and 3 Talent) survive after conversion to OR. Secondary interventions took place in 9 further patients. Of 27 late deaths, 1 suffered endograft sepsis, 20 died of cardio-respiratory causes and 6 died of cancer. The only report of more than a 10-year survival after OR was found in an e-publication from Sweden. The projected survival after 10 years was 40% for unruptured aneurysms. However, survival in the general population was higher at 60%. CONCLUSIONS: Ten-year survival after EVAR parallels that of elective OR but is less than the general population. Although the rate of eventual conversion to open repair was high using this earliest available endograft technology, the aneurysm-related mortality was low, and both endografts remain functional for more than 10 years after placement.
