Examiner workload comparison: three structured oral examination formats for the European diploma in anaesthesiology and intensive care.

The COVID-19 pandemic triggered transformations in academic medicine, rapidly adopting remote teaching and online assessments. Whilst virtual environments show promise in evaluating medical knowledge, their impact on examiner workload is unclear. This study explores examiner's workload during different European Diploma in Anaesthesiology and Intensive Care Part 2 Structured Oral Examinations formats. We hypothesise that online exams result in lower examiner's workload than traditional face-to-face methods. We also investigate workload structure and its correlation with examiner characteristics and marking performance. In 2023, examiner's workload for three examination formats (face-to-face, hybrid, online) using the NASA TLX instrument was prospectively evaluated. The impact of examiner demographics, candidate scoring agreement, and examination scores on workload was analysed. The overall NASA TLX score from 215 workload measurements in 142 examiners was high at 59.61 ± 14.13. The online examination had a statistically higher workload (61.65 ± 12.84) than hybrid but not face-to-face. Primary contributors to workload were mental and temporal demands, and effort. Online exams were associated with elevated frustration. Male examiners and those spending more time on exam preparation experienced a higher workload. Multiple diploma specialties and familiarity with European Diploma in Anaesthesiology and Intensive Care exams were protective against high workload. Perceived workload did not impact marking agreement or examination scores across all formats. Examiners experience high workload. Online exams are not systematically associated with decreased workload, likely due to frustration. Despite workload differences, no impact on examiner's performance or examination scores was found. The hybrid examination mode, combining face-to-face and online, was associated with a minor but statistically significant workload reduction. This hybrid approach may offer a more balanced and efficient examination process while maintaining integrity, cost savings, and increased accessibility for candidates.

Weak Correlation Between Perceived and Measured Intensive Care Unit Nursing Workload: An Observational Study.

BACKGROUND: Efficient management of nursing workload in the intensive care unit (ICU) is essential for patient safety, care quality, and nurse well-being. Current ICU-specific workload assessment scores lack comprehensive coverage of nursing activities and perceived workload. PURPOSE: The purpose of this study was to assess the correlation between ICU nurses' perceived workload and the Nine Equivalents of Nursing Manpower Use Score (NEMS). METHODS: In a 45-bed adult ICU at a tertiary academic hospital, nurses' perceived shift workload (measured with an 11-point Likert scale) was correlated with the NEMS, calculated manually and electronically. RESULTS: The study included 1734 observations. The perceived workload was recorded for 77.6% of observations. A weak positive correlation was found between perceived and objectively measured workload. CONCLUSION: Findings indicate a need to consider the multifaceted nature of nursing activities and individual workload perceptions in the ICU.

The Potential Role of Wearable Inertial Sensors in Laboring Women with Walking Epidural Analgesia.

There is a growing interest in wearable inertial sensors to monitor and analyze the movements of pregnant women. The noninvasive and discrete nature of these sensors, integrated into devices accumulating large datasets, offers a unique opportunity to study the dynamic changes in movement patterns during the rapid physical transformations induced by pregnancy. However, the final cut of the third trimester of pregnancy, particularly the first stage of labor up to delivery, remains underexplored. The growing popularity of "walking epidural", a neuraxial analgesia method allowing motor function preservation, ambulation, and free movement throughout labor and during delivery, opens new opportunities to study the biomechanics of labor using inertial sensors. Critical research gaps exist in parturient fall prediction and detection during walking epidural and understanding pain dynamics during labor, particularly in the presence of pelvic girdle pain. The analysis of fetal descent, upright positions, and their relationship with dynamic pelvic movements facilitated by walking during labor is another area where inertial sensors can play an interesting role. Moreover, as contemporary obstetrics advocate for less restricted or non-restricted movements during labor, the role of inertial sensors in objectively measuring the quantity and quality of women's movements becomes increasingly important. This includes studying the impact of epidural analgesia on maternal mobility, walking patterns, and associated obstetrical outcomes. In this paper, the potential use of wearable inertial sensors for gait analysis in the first stage of labor is discussed.

Relevance of early management by proton-pump inhibitor in acute upper gastro-intestinal tract disorder: A scoping review.

BACKGROUND: Proton-pump inhibitors (PPI) are frequently used in the emergency and general practice settings in several clinical presentations linked to acute upper gastro-intestinal tract disorders as abdominal or chest pain without recommendations. OBJECTIVE: The aim of this scoping review was to assess pain reduction, diagnostic performance, and safety in the first 24 h-management in primary care or emergency medicine. METHODS: Search was realized by 2 independent reviewers in PubMed, Embase, and Web of Science following PRISMA-ScR guidelines. Only original articles or systematic reviews in English were included. Studies about chronic and/or bleeding conditions, therapeutic cocktails and studies without pain evaluation were excluded. Two methodologies were used for bias estimation. RESULTS: From 4442 titles, 79 full-text articles were assessed, and 9 were included. There is no strong evidence supporting the use of PPI as a first line analgesic or diagnostic test in acute syndromes linked to acute upper gastro-intestinal tract disorder. A small effect in pain reduction was retrieved in patients with low pain scores. A poor additional value in patients with gastric reflux, and a low specificity compared to other diagnostic tests were observed. A short-term PPI administration appears to be safe with low risk of serious allergic reactions, and poor adverse effects (moderate evidence). CONCLUSION: Although PPIs may contribute to the multimodal analgesia in acute settings, with few and/or minor side effects, no recommendation can be drawn for their use as a primary analgesic. Data regarding the relevance of the PPI test are much less clear, no data regarding care pathways are available.

Chronic pain characteristics in COVID-19 survivors after an ICU stay. A cross-sectional study.

BACKGROUND: The onset and characteristics of chronic pain following an intensive care unit (ICU) stay for COVID-19 have never been thoroughly investigated. STUDY DESIGN: A multicenter cohort study was conducted to describe chronic pain, according to ICD-11, among COVID-19 survivors. The chronic pain was assessed during face-to-face consultations with a pain specialist. RESULTS: Among 204 COVID-19 ICU survivors, 143 patients with mean age of 60 ± 14 years were included nine months after discharge from the ICU. More than half (54%) of patients experienced new-onset chronic pain. In total, 102 different forms of pain were reported in these patients. Secondary pain was the most frequent type, comprising musculoskeletal (40%), post-traumatic (34%), neuropathic (25%), and visceral (13%). Primary chronic pain was rare (7%). The three most common sites of pain were the shoulders, chest, and head. Pain was moderate to severe in 75% of cases, and higher intensity was associated with a greater impact on daily life. Anxiety, depression, post-traumatic stress, perceived stress, and debilitating pain were frequently associated. Intubation was more frequent in patients with chronic pain. Specialized pain centre follow-up was required for 21% of the survivors, which represented 40% of the patients who developed new-onset chronic pain. CONCLUSION: New-onset chronic pain is common after an ICU stay for COVID-19 and may manifest in various forms. Secondary pain caused by ICU management is the most frequent. Patients should undergo screening after ICU discharge to facilitate prompt, thorough, and personalized pain management. CLINICAL TRIAL REGISTRATION: NCT04940208.

No Benefit of Adductor Canal Block Compared with Anterior Local Infiltration Analgesia in Primary Total Knee Arthroplasty: A Single-Blinded Randomized Controlled Clinical Trial.

BACKGROUND: An adductor canal block (ACB) performed by an anesthesiologist is an established component of analgesia after total knee arthroplasty. Alternatively, surgeons may perform periarticular local infiltration analgesia (LIA) intraoperatively. We hypothesized that ACB would be superior to anterior LIA in terms of morphine consumption in the first 48 hours after primary total knee arthroplasty under spinal anesthesia. METHODS: This prospective controlled and blinded trial included 98 patients; 48 received an ACB plus sham (saline solution) anterior LIA, and 50 received a sham (saline solution) ACB plus anterior LIA. Both groups received posterior LIA with local anesthetic. The primary outcome was cumulative morphine consumption at 48 hours after surgery. Secondary outcomes were pain while resting, standing, and walking, rehabilitation scores, opioid-related side effects, and patient satisfaction. RESULTS: No difference in the primary outcome was found, and the 48-hour morphine consumption was low in both arms (28.8 ± 17.6 mg with ACB, 26.8 ± 19.2 mg with anterior LIA; p = 0.443). Pain scores were significantly better in the anterior LIA arm, but the differences were not clinically relevant. There were no differences in any other secondary outcome measures. CONCLUSIONS: LIA may be used as the primary option for multimodal postoperative pain management in patients undergoing primary total knee arthroplasty with spinal anesthesia. LEVEL OF EVIDENCE: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

Relevance of Visual Acuity Measurement for Therapeutic Decisions in Age-Related Macular Degeneration.

The aim of this study is to assess if the decision to retreat could be determined by anatomical criteria (mostly driven by optical coherence tomography (OCT)-guided strategy) rather than the gold standard (visual acuity (VA) and OCT) in patients with neovascular age-related macular degeneration (nAMD). A cross-sectional study of 142 eyes already treated for nAMD from September 2021 to December 2021 was performed. At inclusion, a first therapeutic decision was made based on the analysis of the OCT. This decision was then maintained or modified after being made aware of the patient's VA. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated. The OCT-guided strategy matched the gold standard for treatment decisions in 131 of the 142 eyes included (92.3%). The sensitivity and specificity of the OCT-guided strategy for the retreatment decision were 94.0% and 89.8%, respectively. PPV and NPV were 92.9% and 91.4%, respectively. Considering the treatment regimen, eyes followed under the Pro ReNata regimen showed better sensitivity (100%) and specificity (93.3%) than eyes followed under the treat and extend regimen (93.5% and 88.6%, respectively). Based on the findings of this study, the follow-up for selected patients with nAMD under anti-VEGF treatment could be monitored without regular VA testing with acceptable performance.

Perioperative Outcomes in Patients Who Received Spinal Chloroprocaine for Total Hip or Knee Arthroplasty-Consecutive Case Series Study.

Spinal anaesthesia is an established component of perioperative management for fast-track lower limbs arthroplasty. Short-acting local anaesthetics may present an interesting option for primary non-complicated knee (TKA) and hip (THA) arthroplasty. We describe the perioperative outcomes in patients operated under fixed 50 mg spinal chloroprocaine for total hip and knee replacement. In this retrospective case series study, 65 patients were analysed (median age 65 years, 55% females, benefit from THA (n = 31), TKA (n = 25), and unicompartmental knee arthroplasty (n = 9)). In all cases, anaesthesia duration (87 min) was sufficient for successful surgery (52 min). Up to 45% of patients (THA and less in TKA) developed postoperative pain in the post-anaesthesia care unit (PACU), requiring intravenous morphine titration (up to 7.5 mg). One patient developed severe breakthrough pain requiring advanced regional analgesia. The median PACU stay was up to 97 min (less in TKA), and the incidence of nausea and urinary retention was low. All patients were able to start physical therapy on the same day of surgery. These findings encourage the use of a short-acting agent for spinal anaesthesia in patients with primary non-complicated arthroplasty; however, the relay analgesia should be systematically implemented to avoid breakthrough pain in PACU.

High-Fidelity Simulation to Assess Task Load Index and Performance: A Prospective Observational Study.

OBJECTIVE: The NASA Task Load Index is a questionnaire widely used in aviation. This index might help for attesting the quality of a scenario in high-fidelity simulation in healthcare. The main purpose of this study was to observe whether NASA Task Load Index for critical care-simulated scenarios, designed for residents, was consistent with the literature. The second purpose was to describe relationships between NASA Task Load Index, performance and generated stress during high-fidelity simulation. METHODS: All residents in anaesthesia and intensive care undergoing high-fidelity simulation were included. The primary endpoint was the task load generated by each scenario assessed by NASA Task Load Index. Based on the literature, the NASA Task Load Index scores between 39 and 61 were considered an acceptable level. Stress level (Visual Analogue Scale) and specific technical and non-technical skills performances (Team Emergency Assessment Measure) were also assessed. RESULTS: Totally 53 residents actively participated in 1 of 10 different scenarios, between June and December 2017. The median NASA Task Load Index score of scenarios was 61 [48-65]. Five scenarios generated acceptable task load levels. There was no association between the NASA Task Load Index score and technical or non-technical skills performance scores, but an association between NASA Task Load Index and the stress level (rho=4.7, P =.001) was observed. CONCLUSION: Simulation scenarios generate different task loads for residents; the task load was deemed acceptable for half of the scenarios. The NASA Task Load Index could be considered as a tool to assess the pedagogic adequacy of scenarios. Scenario and generated stress level, but not task load, can modify residents' performance during simulation. This should be considered when planning normative simulation.

Nefopam prescribing preferences in French hospitals: results of a survey.

Introduction: nefopam is a non-opioid, centrally-acting analgesic, frequently prescribed in France for acute pain and postoperatively. Only intravenous (IV) formulation is available, however the off-label oral use is frequent in surgical and medical patients. There is no data on the actual in-hospital prescription preferences in French physicians regarding nefopam. We wish to identify nefopam prescription habits for acute and chronic pain among hospital physicians. Methods: an online survey was sent to physicians via professional emails. Frequency of prescription, indication, preferred and prescribed administration route, dose regimen, and personal perception of the nefopam tolerance and efficiency were examined. Results: a total of 527 responses were analysed. Nefopam was mostly prescribed by senior hospital physicians, for acute pain, orally (85%), 20 mg/6h with 120 mg maximal daily dose. For chronic pain, the oral administration was more frequent. More than half of prescribers considered the efficacy of the oral route was similar to intravenous, and better tolerated compared to intravenous administration. Forty-eight percent of responders would change their prescription attitude in case of oral route approval of nefopam. Conclusion: oral prescription of intravenous formulation of nefopam is frequent, especially for acute pain, and has the same dose and regimen pattern as for intravenous route. Prescribers consider oral nefopam efficient and safe for patients. Regulatory actions regarding the oral nefopam prescription authorization and duration of such prescription are needed.

Preoperative Anxiety in the Surgical Transfer and Waiting Area: A Cross-Sectional Mixed Method Study.

Severe preoperative anxiety (SPA) in surgical patients may have clinical consequences and worsen satisfaction. Some institutions have a surgical transfer and waiting area (TWA) for patient reception/dispatch to operating rooms. We measured the frequency of SPA, investigated predicting factors, and quantified the effect of the TWA stay on anxiety levels in a single centre cross-sectional study. Preoperative anxiety was assessed using three scales. Patients' perceptions/suggestions were studied by a psychoanalyst. A total of 933 adult patients, undergoing elective procedures, were interviewed. SPA was detected in 24.7%, non-modified by anxiolytic premedication. Patients' median stay was 9 min, and anxiety level was decreasing in those with SPA. In multivariable analysis, female sex, inpatient settings, and pain before the procedure were predictive for SPA. Previous operating room experience, and a supine arrival position were associated with less SPA. Patients complained about a lack of information, and an uncomfortable environment in the waiting area. To reduce anxiety, they mainly asked for warm blankets/music (physical/sound barriers), and extra sedative agents. The holding area may be a place to measure patients' anxiety by paramedical staff, and to apply simple non-pharmacological interventions. The psychological concept of psychical envelopes may be useful for the development and investigation of such interventions in improving patients' experience.

Impact of COVID-19 on chronic pain structures: data from French national survey.

Aims: The authors evaluated the impact of the first COVID-19 pandemic wave on French chronic pain structures (CPS). Methods: An online survey assessed CPS resource allocation, workflow and perceived impact on patient care. Results: All CPS workflow was severely impacted by the reallocation of 42% of specialists. In-person appointments were cancelled by 72% of participants. Follow-up was maintained in 91% of participants (telemedicine). Skills in end-of-life decision-making/counseling were rarely solicited. The perceived impact of the crisis on the experience of patients was high (eight out of ten), with a significant increase in access-to-care delay. Conclusion: CPS maintained patient follow-up. Special features of CPS specialists were rarely solicited by COVID-19 teams experiencing a high workload. Recommendations on optimal CPS resource reallocations have to be standardized in crisis conditions.

Preoperative Education for Less Outpatient Pain after Surgery (PELOPS trial) in orthopedic patients-study protocol for a randomized controlled trial.

BACKGROUND: Successful pain management after outpatient surgery requires proper education leading to correct decisions on the analgesics use at home. Despite different strategies adopted, up to ½ of patients receive little or no information about the treatment of postoperative pain, 1/3 of them are not able to follow postoperative analgesia instructions. This leads to higher rates of unmet needs in pain treatment, post-discharge emergency calls, and readmissions. Structured educational interventions using psychological empowering techniques may improve postoperative pain management. We hypothesize that preoperative education on use of an improved pain scale to make correct pain management decisions will improve the quality of post-operative pain management at home and reduce analgesics-related side effects. METHODS: A total of 414 patients scheduled for an outpatient orthopedic surgery (knee/shoulder arthroscopic interventions) are included in this randomized (1:1) controlled trial. Patients in the control arm receive standard information on post-discharge pain management. Patients in the experimental arm receive structured educational intervention based on the rational perception of postoperative pain and discomfort (anchoring and improved pain scale), and the proper use of analgesics. There is no difference in post-discharge analgesics regimen in both arms. Patients are followed for 30 days post-discharge, with the primary outcome expressed as total pain relief score at 5 days. Secondary outcomes include the incidence of severe pain during 30 days, changes in sleep quality (Pittsburg Sleep Quality Assessment), and patients' perception of postoperative pain management assessed with the International Pain Outcomes questionnaire at day 30 post-discharge. DISCUSSION: The developed intervention, based on an improved pain scale, offers the advantages of being non-surgery-specific, is easily administered in a short amount of time, and can be delivered individually or in-group, by physicians or nurses. TRIAL REGISTRATION: ClinicalTrials.gov NCT03754699 . Registered on November 27, 2018.

Auricular Acupuncture for Preoperative Anxiety in Parturient Women with Scheduled Cesarean Section: A Randomized Placebo-Controlled Blind Study.

Introduction: Preoperative anxiety before cesarean section is a major issue. Nonpharmacologic anxiety control is believed to be more suitable in pregnant women. Auricular acupuncture (AA) is an inexpensive, easy-to-use, and validated intervention to reduce anxiety in different surgical settings. We evaluated the effect of AA on preoperative cesarean section anxiety. Methods: In a prospective, blind, controlled trial, pregnant women with a scheduled cesarean section under spinal anesthesia were randomized to receive AA with needle, AA without needle (sham), or usual care (no intervention). Anxiety level was assessed by using a visual analogue scale for anxiety (VAS-A; 0-minimal anxiety, 100-maximal anxiety) at three time points: inclusion (pre-induction room-T0), when entering the operating room (T1), and before incision (T2). The primary outcome was the VAS-A variation (percentage changes) between T0 and T1 in the AAe group compared with that in the sham AA group. The secondary outcomes were the VAS-A variation between T0 and T1 in the AA group compared with that in the control group, and the variation between T0 and T2 compared between the three groups, the effect of AA on parasympathetic tone, and the incidence of adverse effects. Results: In women immediately before anesthesia for cesarean section, the AA produced a 19% decrease of anxiety, compared with a 21% anxiety increase in sham AA, which is significantly different. The effect of AA was more present in women with low initial anxiety. The proportion of patients reaching clinically significant anxiety reduction (>33% from the initial level) was 2.5 times higher in the AA group (p = 0.02) compared with the sham group. No differences in anxiety variations were found compared with the no-intervention group. No effect of AA was noted on parasympathetic tone. Conclusion: Compared with sham, AA decreased maternal anxiety level when arriving in the operation room and just before the beginning of the cesarean section, with a trend toward improvement compared with usual care.

Risk Factors for COVID-19 Associated Mucormycosis: The Ophthalmologist's Perspective.

The COVID-19 pandemic has led to a dramatic rise in the incidence of rhino-orbito-cerebral mucormycosis (ROCM) in India. The purpose of our report is to describe the prevalence of ROCM in the context of SARS-CoV-2 infection during the second Indian COVID-19 wave, as well as its diagnostics proceeding, and to discuss the challenges met in the time frame from the suspected diagnosis to the therapeutic decision in such patients. We conducted a retrospective multicentre case series study at six centres of Sudhalkar and Raghudeep group of hospitals in India. ROCM was confirmed in 38 (2.5%) of the 1546 patients admitted with SARS-CoV-2 infection. The average time to establish a diagnosis was 16 days. In total, 19 (50%) patients suffered from type 2 diabetes and were mostly treated with hypoglycaemic agents (in 90% of cases). The standard of care for SARS-CoV-2 management included systemic steroids therapy, intravenous remdesivir for 5 days, and concomitant prophylactic antibiotic therapy following admission. The median (IQR) blood glucose levels in all patients during the course of hospitalisation was 320 (250.5-375) mg/dl. A total of 16% of patients had an irreparable functional loss, and the mortality was 5%. We may hypothesise that excessive administration of antibiotics that profoundly affects human microbiota, coupled with poorly controlled glycaemia and unprotocolised haphazard steroid administration, contribute to a favourable setting for mucormycosis infections.

Usability evaluation of sufentanil sublingual tablet analgesia in patients following Enhanced Recovery After Surgery.

Aim: To evaluate the usability and satisfaction from the sufentanil sublingual tablet system analgesia in the Enhanced Recovery After Surgery pathway in patients, nurses and physical therapist. Materials & methods: A system usability scale was used to evaluate analgesia system in the prospective observational study in spine, orthopedic and thoracic patients. Result: In 111 cases the median system usability scale score was 90 (80-100) (patients) and 72.5 (57.5-82.5) (nurses). The median satisfaction score of the physiotherapist was 90 (75-100). Conclusion: The usability and the satisfaction of the patients and the caregivers from sufentanil sublingual tablet system analgesia in the context of Enhanced Recovery After Surgery protocol were good-to-excellent. The economic potential in the reduction of hospital stay should be studied. Trial registration number: NCT03373851 (ClinicalTrial.gov).

Anemia before reimplantation surgery - An overlooked modifiable risk factor of septic revision knee arthroplasty failure.

INTRODUCTION: Preoperative anemia in patients undergoing a two-stage septic revision arthroplasty may be a factor of reinfection, even in the presence of aggressive antimicrobial therapy. Patient Blood Management (PBM) in such patients is challenging. We evaluate the impact of anemia existing before re-implantation on a failure rate after two-stage septic total knee arthroplasty (rTKA), and explore feasibility of a PBM strategy implementation in these patients. MATERIALS AND METHODS: A retrospective study of patients from January 2010 to January 2015 in a French regional referral center was performed. Patients undergoing a two-stage rTKA for infection after successful primary TKA were identified and followed up to 31.12.2018. The primary outcome (failure) was defined as surgical site infection after re-implantation requiring new surgery. The secondary outcomes were time to failure, the time between explantation/reimplantation, transfusion rate during the second stage. Preoperative anemia was defined as Hb level < 12 g/L before the re-implantation. RESULTS: 69 patients were identified; 17 (24%) developed reinfection of rTKA in 105 [11.4-156] days. In these patients pre-implantation anemia was more frequent (n = 13(76.5%) in failed vs. n = 21(40%) in non-failed, p = 0.0110). During the explantation stage, there were no significant group differences in age, sex, comorbidity, type of spacer and antimicrobial therapy, iron supplementation, or transfusion rate. The median time between explantation/reimplantation surgery was 51 [43-71.5] days, indifferent between the two groups. Intraoperative transfusion during reimplantation was required in 12 (17%) patients, more frequent in failed patients. None of the patients had contraindications for the PBM strategy except the cell-saver use. CONCLUSION: In two-stage septic rTKA preoperative anemia was almost two times more frequent and associated with an elevated rate of septic failure. The time-frame between explantation and-re-implantation is sufficient to implement a PBM strategy for all anemic patients. Before-after studies would be of interest to determine the best PBM strategy to prevent anemia-associated septic failure in such a condition.

Management of postdischarge nausea and vomiting.

Postdischarge nausea and vomiting (PDNV) occurs in at least 30% of patients leaving hospital, especially after day-case surgery. A significant number of ambulatory patients may develop PDNV associated with the use of analgesics for postsurgical pain. A validated PDNV prediction score and international evidence-based consensus guidelines for PONV/PDNV management are available. High-risk patients benefit from a predischarge PDNV risk assessment and the use of adapted pharmacological intervention (combination of long- and short-acting antiemetics and access to antiemetics at home). Patient education is often overlooked in this context. All clinicians involved in the ambulatory surgery care process should participate in the development of institutional protocol for PONV/PDNV management. Constant quality control and patients' feedback should be integrated as part of an efficient implementation strategy.

Causes and mechanisms of isolated mitral regurgitation in the community: clinical context and outcome.

AIMS: To define the hitherto unknown aetiology/mechanism distributions of mitral regurgitation (MR) in the community and the linked clinical characteristics/outcomes. METHODS AND RESULTS: We identified all isolated, moderate/severe MR diagnosed in our community (Olmsted County, MN, USA) between 2000 and 2010 and classified MR aetiology/mechanisms. Eligible patients (n = 727) were 73 ± 18 years, 51% females, with ejection fraction (EF) 49 ± 17%. MR was functional (FMR) in 65%, organic (OMR) in 32% and 2% mixed. Functional MR was linked to left ventricular remodelling (FMR-v) 38% and isolated atrial dilatation (FMR-a) 27%. At diagnosis FMR-v vs. FMR-a, vs. OMR displayed profound differences (all P < 0.0001) in age (73 ± 14, 80 ± 10, 68 ± 21years), male-sex (59, 33, 51%), atrial-fibrillation (28, 54, 13%), EF (33 ± 14, 57 ± 11, 61 ± 10%), and regurgitant-volume (38 ± 13, 37 ± 11, 51 ± 24 mL/beat). Dominant MR mechanism was Type I (normal valve-movement) 38%, Type II (excessive valve-movement) 25%, Type IIIa (diastolic movement-restriction) 3%, and Type IIIb (systolic movement-restriction) 34%. Outcomes were mediocre with excess-mortality vs. general-population in FMR-v [risk ratio 3.45 (2.98-3.99), P < 0.0001] but also FMR-a [risk ratio 1.88 (1.52-2.25), P < 0.0001] and OMR [risk ratio 1.83 (1.50-2.22), P < 0.0001]. Heart failure was frequent, particularly in FMR-v (5-year 83 ± 3% vs. 59 ± 4% FMR-a, 40 ± 3% OMR, P < 0.0001). Mitral surgery during patients' lifetime was performed in 4% of FMR-v, 3% of FMR-a, and 37% of OMR. CONCLUSION: Moderate/severe isolated MR in the community displays considerable aetiology/mechanism heterogeneity. Functional MR dominates, mostly FMR-v but FMR-a is frequent and degenerative MR dominates OMR. Outcomes are mediocre with excess-mortality particularly with FMR-v but FMR-a, despite normal EF incurs notable excess-mortality and frequent heart failure. Pervasive undertreatment warrants clinical trials of therapies tailored to specific MR cause/mechanisms.
