Patient and provider perspectives on pain and other dimensions of anesthesia experience for cesarean delivery: A qualitative study.

Background: There is a lack of evidence on the importance of pain or other aspects of clinical care in the overall patient experience and patient-centered outcomes in cesarean delivery. The purpose of this study was to discover patient priorities in cesarean delivery anesthesia experience, to compare patient and provider perspectives, and to explore attitudes on shared decision-making around anesthesia choices for cesarean delivery. Methods : Patients with recent cesarean deliveries and clinical care providers were approached using a purposeful sampling strategy for this prospective observational qualitative study. Patients were included if they were in the hospital within 72 hours of a cesarean delivery (scheduled or unscheduled), spoke English fluently, and had term gestation. Providers were included if they currently provide regular clinical care to patients having cesarean deliveries and have at least 3 years of practice experience. Semi-structured interviews were conducted using an interview guide. Interview transcripts were independently coded by three coders and qualitatively analyzed for major themes until thematic saturation was achieved. Results : A total of 42 participants (20 patients and 22 providers) completed interviews. Five major themes emerged reflecting patient attitudes and beliefs toward cesarean delivery experience: 1) effective communication, education, and respect; 2) emotional support by care team; 3) intraoperative pain or discomfort; 4) varying acceptability around pain therapies; 5) stigma surrounding cesarean delivery. Five major themes emerged reflecting provider attitudes and beliefs toward cesarean delivery priorities: 1) complexity of pain responses; 2) multiple pain control strategies; 3) effective communication during emergency cesarean delivery; 4) patient psychological well-being during cesarean delivery; 5) barriers to observing the patients' birth plans. Conclusions : Patients and providers alike prioritize pain management, psychological well-being, and effective communication during cesarean delivery experiences. Patients emphasize relationships and trust in their cesarean experience, while clinicians emphasize clinical complexities and physical treatments. Our results guide future research in patient perspectives in cesarean deliveries.

Maternal-Fetal Conflicts in Anesthesia Practice.

Anesthesia clinicians often navigate a delicate balance between maternal and fetal safety. Interventions for at fetal well-being may introduce risks of harm to the mother and raise ethical dilemmas. Emergency procedures often focus on direct fetal safety, sidelining maternal physical and mental well-being. The clash between ethical principles, particularly nonmaleficence and beneficence, often arises, with maternal autonomy guiding decisions. Fetal surgery exemplifies risking maternal health for fetal benefit, whereas emergent cesarean deliveries pose physical and psychological challenges for both the mother and child.

Obstetric operating room staffing and operating efficiency using queueing theory.

INTRODUCTION: Strategies to achieve efficiency in non-operating room locations have been described, but emergencies and competing priorities in a birth unit can make setting optimal staffing and operation benchmarks challenging. This study used Queuing Theory Analysis (QTA) to identify optimal birth center operating room (OR) and staffing resources using real-world data. METHODS: Data from a Level 4 Maternity Center (9,626 births/year, cesarean delivery (CD) rate 32%) were abstracted for all labor and delivery operating room activity from July 2019-June 2020. QTA has two variables: Mean Arrival Rate, λ and Mean Service Rate µ. QTA formulas computed probabilities: P0 = 1-(λ/ µ) and Pn = P0 (λ/µ)n where n = number of patients. P0…n is the probability there are zero patients in the queue at a given time. Multiphase multichannel analysis was used to gain insights on optimal staff and space utilization assuming a priori safety parameters (i.e., 30 min decision to incision in unscheduled CD; ≤ 5 min for emergent CD; no greater than 8 h for nil per os time). To achieve these safety targets, a < 0.5% probability that a patient would need to wait was assumed. RESULTS: There were 4,017 total activities in the operating room and 3,092 CD in the study period. Arrival rate λ was 0.45 (patients per hour) at peak hours 07:00-19:00 while λ was 0.34 over all 24 h. The service rate per OR team (µ) was 0.87 (patients per hour) regardless of peak or overall hours. The number of server teams (s) dedicated to OR activity was varied between two and five. Over 24 h, the probability of no patients in the system was P0 = 0.61, while the probability of 1 patient in the system was P1 = 0.23, and the probability of 2 or more patients in the system was P≥2 = 0.05 (P3 = 0.006). However, between peak hours 07:00-19:00, λ was 0.45, µ was 0.87, s was 3, P0 was 0.48; P1 was 0.25; and P≥2 was 0.07 (P3 = 0.01, P4 = 0.002, P5 = 0.0003). CONCLUSION: QTA is a useful tool to inform birth center OR efficiency while upholding assumed safety standards and factoring peaks and troughs of daily activity. Our findings suggest QTA is feasible to guide staffing for maternity centers of all volumes through varying model parameters. QTA can inform individual hospital-level decisions in setting staffing and space requirements to achieve safe and efficient maternity perioperative care.

Translational research updates in female health anesthesiology: a narrative review.

Background and Objective: Females represent 49.6% of the global population and constitute a significant proportion of surgical patients and hospital admissions. Little is known about the bi-directional effects of sex and anesthetics or the impact of anesthetic interventions on long-term female health outcomes. Sex differences in pain pathways can influence pain experience and treatment effectiveness. The impact of anesthetic management on the recurrence of breast cancer is poorly understood, as are the long-term consequences of cardiovascular disease and safe and effective treatments in pregnancy. This review aims to outline recent advances in translational science in female health anesthesiology research and highlight critical research opportunities in pain, cancer outcomes, and cardiovascular disorders. Methods: We searched PubMed and summarized relevant articles published in English between December 2021 and June 2022. Key Content and Findings: Studies reveal sex differences in pain pathways and highlight the importance of sex as a biological variable in experimental designs and translational medicine. Sex differences have also been observed in side effects attributed to opioid analgesics. We summarize some of the neural circuits that might underlie these differences. In the perioperative setting, specific anesthetics are implicated in metastatic seeding potential and acute and chronic pain outcomes, suggesting the importance of anesthetic selection in comprehensive care during oncologic surgery. In the peridelivery setting, preeclampsia, a cardiovascular disorder of pregnancy, affects maternal outcomes; however, biomarkers can risk-stratify females at risk for preeclampsia and hold promise for identifying the risk of adverse neurological and other health outcomes. Conclusions: Research that builds diagnostic and predictive tools in pain and cardiovascular disease will help anesthesiologists minimize sex-related risks and side effects associated with anesthetics and peri-hospital treatments. Sex-specific anesthesia care will improve outcomes, as will the provision of practical information to patients and clinicians about the effectiveness of therapies and behavioral interventions. However, more research studies and specific analytic plans are needed to continue addressing sex-based outcomes in anesthesiology.

Evidence-based clinical practice guidelines on postdural puncture headache: a consensus report from a multisociety international working group.

INTRODUCTION: Postdural puncture headache (PDPH) can follow unintentional dural puncture during epidural techniques or intentional dural puncture during neuraxial procedures such as a lumbar puncture or spinal anesthesia. Evidence-based guidance on the prevention, diagnosis or management of this condition is, however, currently lacking. This multisociety guidance aims to fill this void and provide practitioners with comprehensive information and patient-centric recommendations to prevent, diagnose and manage patients with PDPH. METHODS: Based on input from committee members and stakeholders, the committee cochairs developed 10 review questions deemed important for the prevention, diagnosis and management of PDPH. A literature search for each question was performed in MEDLINE (Ovid) on 2 March 2022. The results from each search were imported into separate Covidence projects for deduplication and screening, followed by data extraction. Additional relevant clinical trials, systematic reviews and research studies published through March 2022 were also considered for the development of guidelines and shared with contributors. Each group submitted a structured narrative review along with recommendations graded according to the US Preventative Services Task Force grading of evidence. The interim draft was shared electronically, with each collaborator requested to vote anonymously on each recommendation using two rounds of a modified Delphi approach. RESULTS: Based on contemporary evidence and consensus, the multidisciplinary panel generated 50 recommendations to provide guidance regarding risk factors, prevention, diagnosis and management of PDPH, along with their strength and certainty of evidence. After two rounds of voting, we achieved a high level of consensus for all statements and recommendations. Several recommendations had moderate-to-low certainty of evidence. CONCLUSIONS: These clinical practice guidelines for PDPH provide a framework to improve identification, evaluation and delivery of evidence-based care by physicians performing neuraxial procedures to improve the quality of care and align with patients' interests. Uncertainty remains regarding best practice for the majority of management approaches for PDPH due to the paucity of evidence. Additionally, opportunities for future research are identified.

Development of obstetric anesthesia core competencies for USA residency programs through a Delphi process.

PURPOSE: The standard for anesthesia residency training in the USA mainly relies on the Accreditation Council for Graduate Medical Education (ACGME) Outcome Project, a framework that lacks specific directives for subspecialties including obstetric anesthesia. We aimed to identify core competencies in obstetric anesthesiology that can be adapted to different residency training programs to help improve the quality of training and accountability of the institutions within the USA. METHODS: We identified a preliminary list of competencies from review of existing competency-based obstetric anesthesia training curricula and practice guidelines. We used a modified Delphi methodology to achieve expert consensus among members of the Society for Obstetric Anesthesia and Perinatology education committee. The panellists were asked to evaluate the importance of each competency using a five-point Likert scale, with consensus after two rounds defined at 80% agreement. The responders were also asked at which level of training each competency should be attained. RESULTS: The Delphi rounds had 75% response rate and derived 94 competencies that were categorized under the six ACGME domains: patient care (38), medical knowledge (45), system-based practice (two), practice-based learning and improvement (five), interpersonal communication skills (two), and professionalism (two). CONCLUSION: We generated a residency training competency list for obstetric anesthesiology through expert consensus. This list can be used by residency training programs to develop a structured competency-based curriculum with tangible milestones, thereby reducing heterogeneity in the standard of training.

RéSUMé: OBJECTIF: La norme pour la formation en résidence en anesthésie aux États-Unis repose principalement sur le Projet de résultats (Outcome Project) de l'Accreditation Council for Graduate Medical Education (ACGME), un cadre qui ne dispose pas de directives spécifiques pour les surspécialités, notamment pour l'anesthésie obstétricale. Notre objectif était d'identifier les compétences de base en anesthésiologie obstétricale qui pourraient être adaptées aux différents programmes de formation en résidence afin d'améliorer la qualité de la formation et la responsabilisation des établissements aux États-Unis. MéTHODE: Nous avons dressé une liste préliminaire de compétences en passant en revue les programmes de formation axés sur les compétences et les lignes directrices de pratique existants en anesthésie obstétricale. Nous avons utilisé une méthodologie Delphi modifiée pour parvenir à un consensus d'expert·es parmi les membres du comité d'éducation de la Society for Obstetric Anesthesia and Perinatology. Les panélistes ont été invité·es à évaluer l'importance de chaque compétence à l'aide d'une échelle de Likert à cinq points, le consensus étant défini à 80 % d'accord après deux tours. On a également demandé aux répondant·es à quel niveau de formation chaque compétence devrait être atteinte. RéSULTATS: Les étapes du processus Delphi ont eu un taux de réponse de 75 % et ont permis de déterminer 94 compétences qui ont été classées dans les six domaines ACGME : soins aux patient·es (38), connaissances médicales (45), pratique systémique (deux), apprentissage et amélioration basés sur la pratique (cinq), compétences en communication interpersonnelle (deux) et professionnalisme (deux). CONCLUSION: Nous avons généré une liste de compétences pour la formation de résidence en anesthésiologie obstétricale grâce à un consensus d'expert·es. Cette liste peut être utilisée par les programmes de formation en résidence pour élaborer un programme structuré axé sur les compétences avec des jalons tangibles, réduisant ainsi l'hétérogénéité dans la norme de formation.

Consensus Practice Guidelines on Postdural Puncture Headache From a Multisociety, International Working Group: A Summary Report.

Importance: Postdural puncture headache (PDPH) can follow unintentional dural puncture during epidural techniques or intentional dural puncture during neuraxial procedures, such as a lumbar puncture or spinal anesthesia. Evidence-based guidance on the prevention, diagnosis, and management of this condition is, however, currently lacking. Objective: To fill the practice guidelines void and provide comprehensive information and patient-centric recommendations for preventing, diagnosing, and managing PDPH. Evidence Review: With input from committee members and stakeholders of 6 participating professional societies, 10 review questions that were deemed important for the prevention, diagnosis, and management of PDPH were developed. A literature search for each question was performed in MEDLINE on March 2, 2022. Additional relevant clinical trials, systematic reviews, and research studies published through March 2022 were also considered for practice guideline development and shared with collaborator groups. Each group submitted a structured narrative review along with recommendations that were rated according to the US Preventive Services Task Force grading of evidence. Collaborators were asked to vote anonymously on each recommendation using 2 rounds of a modified Delphi approach. Findings: After 2 rounds of electronic voting by a 21-member multidisciplinary collaborator team, 47 recommendations were generated to provide guidance on the risk factors for and the prevention, diagnosis, and management of PDPH, along with ratings for the strength and certainty of evidence. A 90% to 100% consensus was obtained for almost all recommendations. Several recommendations were rated as having moderate to low certainty. Opportunities for future research were identified. Conclusions and Relevance: Results of this consensus statement suggest that current approaches to the treatment and management of PDPH are not uniform due to the paucity of evidence. The practice guidelines, however, provide a framework for individual clinicians to assess PDPH risk, confirm the diagnosis, and adopt a systematic approach to its management.

Simultaneous quantitation of ketamine, norketamine and dehydronorketamine in human milk using a novel ultra high-performance liquid chromatography-mass spectrometry (UPLC-MS/MS) assay.

There is a paucity of data on the transfer of ketamine from maternal blood into human milk. Quantification of ketamine in human milk provides information about the potential exposure of the infant to ketamine and its metabolites from the mother during lactation. A highly specific, reproducible, and sensitive UPLC-MS/MS based analytical method was developed and validated for the quantitation of ketamine and its metabolites (norketamine and dehydronorketamine) in human milk. Samples were subjected to a simple protein precipitation and ketamine-d4 and norketamine-d4 were used as internal standards. Separation of the analytes was achieved using an Acquity UPLC equipped with BEH RP18 1.7 µm, 2.1 × 100 mm column. Mass spectrometric analysis of the analyte ions was carried out using electrospray with positive ionization and multiple reaction monitoring mode. The assay was linear over a concentration range of 1-100 ng/mL for ketamine and norketamine, and 0.1-10 ng/mL for dehydronorketamine. Acceptable intra-day and inter-day accuracy and precision were observed for all the analytes. High recovery of the analytes and minimal matrix effect were observed. Stability of analytes was confirmed at the tested conditions. This assay was successfully used to measure analytes in human milk samples collected from lactating women enrolled in a clinical research study. This is the first validated method that simultaneously quantified ketamine and its metabolites in human milk.

Longitudinal cognitive evaluation before and after delivery among people with preeclampsia.

BACKGROUND: Cognitive impairments related to preeclampsia after pregnancy have been reported; however, it is not known if weaknesses in cognition occur before and shortly after delivery. OBJECTIVE: This study aimed to assess the feasibility of longitudinal cognitive testing before and after delivery, and to investigate whether those with preeclampsia have cognitive weaknesses during the third trimester of pregnancy and at 1 and 3 months postpartum. We hypothesized that people with preeclampsia would have lower cognition scores across all time points compared with normotensive people. STUDY DESIGN: This longitudinal, prospective, observational study in a single institution enrolled people (N=30) at ≥28 weeks of gestation with preeclampsia (N=16) or normotension (N=14). People with chronic hypertension, neurologic or developmental disabilities, moderate or severe depression or anxiety, or current substance use were excluded. Subjective (Everyday Cognition Scale) and objective assessment of executive function (Stroop Color-Word Interference Test, Trail-Making Test), attention and working memory (Digit Span subtest), and information processing speed (Digit Symbol Substitution Test) was conducted, and Z-scores were calculated. Baseline characteristics (eg, prepregnancy body mass index) were collected from the medical record. Generalized linear models were used to estimate associations. RESULTS: We enrolled 37% (30/81) of eligible people and retained 80% (24/30) and 53% (16/30) at 1 and 3 months postpartum, respectively. People with preeclampsia reported more memory problems (ß=0.87; 95% confidence interval, 0.44-1.31), and scored worse on attention and working memory (ß=-0.94; 95% confidence interval, -1.42 to -0.45) and executive function (Stroop test ß=-0.86; 95% confidence interval, -1.53 to -0.19) domains compared with normotensive people after adjusting for time, age, education, and prepregnancy body mass index. CONCLUSION: Longitudinal assessment of cognition in pregnant preeclamptic and normotensive people is feasible. People with preeclampsia reported worse subjective memory and had lower scores in attention, working memory, and executive function.

Effects of digital health interventions on the psychological outcomes of perinatal women: umbrella review of systematic reviews and meta-analyses.

ABSTRACTEvidence about the effects of digital health interventions (DHIs) on the psychological outcomes of perinatal women is increasing but remains inconsistent. An umbrella review was conducted to (1) assess the effect of DHIs on depressive, anxiety and stress symptoms and (2) compare the effects of DHIs on different digital platforms and population natures. Ten databases were searched from inception until December 23, 2022. The Hartung-Knapp-Sidik-Jonkman random-effects meta-analyses were utilised. Methodological quality was evaluated using the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2). Twenty-four systematic reviews with 41 meta-analyses involving 45,509 perinatal women from 264 primary studies were included. The credibility of the evidence of meta-analyses was rated as highly suggestive (4.88%), suggestive (26.83%), weak (51.22%) or non-significant (17.07%) according to AMSTAR-2. Our findings suggest that DHIs are beneficial for reducing stress symptoms. However, conflicting effects were found on anxiety symptoms. Subgroup and meta-regression analyses suggested that DHIs effectively improve depressive symptoms in postnatal women, and DHIs using the website platform are highly effective in stress reduction. DHIs can be implemented adjuvant to usual obstetric care to improve depressive and stress symptoms. Additional well-designed RCTs with long-term follow-up are warranted.

A Case Series of Parturients With Mechanical Mitral Valves: Anticoagulation Management During Labor and Delivery.

More women with mechanical mitral valves (MMVs) are pursuing pregnancy. Guidelines exist for pregnancy anticoagulation, but they do not address individualized anticoagulation during delivery-a period of risk for bleeding, thrombosis, and anesthetic complications. This case series of parturients with MMVs highlights the challenges in, and the evidence and strategies for, treating these patients. (Level of Difficulty: Advanced.).

Analgesia in Pregnancy.

Pain management during labor and delivery is complex and must balance efficacy and toxicity to both the pregnant person and the fetus. There are numerous ways to achieve safe and effective analgesia and anesthesia during labor and delivery, including neuraxial and nonneuraxial techniques. This review describes important anesthetic considerations that should be made when formulating a pain management plan and an overview of common anesthesia-related complications encountered in the obstetric population.

Opioids and Opioid Use Disorder in Pregnancy.

Overdose is a leading cause of pregnancy-associated morbidity and mortality in the United States. As such, all obstetric providers have a responsibility to provide evidence-based care for patients with opioid use disorder to mitigate adverse outcomes associated with substance use during pregnancy.

Obstetric pain management for pregnant women with opioid use disorder: A qualitative and quantitative comparison of patient and provider perspectives (QUEST study).

BACKGROUND AND AIM: Patients with opioid use disorder (OUD) may experience inadequate pain management especially during childbirth. This study assessed and compared patient and provider perspectives on analgesia during and after delivery in women with OUD. DESIGN: Prospective cohort, mixed method design including semi-structured interviews and structured surveys with pregnant or recently pregnant patients (n = 17) and provider (n = 15) groups. SETTING: Prenatal clinics and hospital postpartum units. PARTICIPANTS: Patients were pregnant women with OUD currently treated with methadone (n = 1) or buprenorphine (n = 16). Providers were obstetricians (n = 5), obstetric nurses (n = 5) and anesthesiologists (n = 5). MEASUREMENTS: Validated questionnaires were completed by both groups; patient interviews were conducted during the third trimester and at 5 days post-delivery. Patient topics included pain management preferences, analgesia satisfaction and attitudes toward pain. Provider topics included labor and postpartum pain management perspectives. Interviews were independently coded and qualitatively analyzed for major themes. FINDINGS: Five major themes emerged from patient interviews: (1) neuraxial blockade was endorsed for labor pain; (2) otherwise, limited pain control options were perceived; (3) no consensus around use of opioids for pain; (4) non-opioid options should be available; and (5) provider communication and health-care system issues act as barriers to adequate pain management. Provider perspective themes included the following: (1) unique challenges in pain management for patients with OUD; (2) confusion on how to plan for and make perinatal adjustments to medication for OUD; (3) discrepant views on use of opioids for pain management; (4) endorsement of non-pharmacological and non-opioid options; and (5) need for improved provider collaboration in developing pain management plans. CONCLUSIONS: Patients with opioid use disorder and health-care providers prioritize pain management during and after childbirth, but have discrepant views on use of opioids and other pain management options. Inadequate care coordination and discrepancies in opinions need to be addressed both within care teams and between patients and providers. Clinicians would benefit from better evidence to guide clinical care of patients with OUD for patient-centered pain management.

An Observational Data Meta-analysis on the Differences in Prevalence and Risk Factors Between MAFLD vs NAFLD.

BACKGROUND & AIMS: The shift to redefine nonalcoholic fatty liver disease (NAFLD) as metabolic associated fatty liver disease (MAFLD) can profoundly affect patient care, health care professionals, and progress within the field. To date, there remains no consensus on the characterization of NAFLD vs MAFLD. Thus, this study sought to compare the differences between the natural history of NAFLD and MAFLD. METHODS: Medline and Embase databases were searched to include articles on prevalence, risk factors, or outcomes of patients with MAFLD or NAFLD. Meta-analysis of proportions was conducted using the generalized linear mix model. Risk factors and outcomes were evaluated in conventional pairwise meta-analysis. RESULTS: Twenty-two articles involving 379,801 patients were included. Pooled prevalence of MAFLD was 39.22% (95% confidence interval [CI], 30.96%-48.15%) with the highest prevalence in Europe and Asia, followed by North America. The current MAFLD Definition only accounted for 81.59% (95% CI, 66.51%-90.82%) of NAFLD diagnoses. Patients had increased odds of being diagnosed with MAFLD compared with NAFLD (odds ratio, 1.37; 95% CI, 1.16-1.63; P < .001). Imaging modality resulted in a significantly higher odds of being diagnosed with MAFLD compared with NAFLD, but not biopsy. MAFLD was significantly associated with males, higher body mass index, hypertension, diabetes, lipids, transaminitis, and greater fibrosis scores compared with NAFLD. CONCLUSIONS: There were stark differences in the prevalence and risk factors between MAFLD and NAFLD. However, in the use of the MAFLD Definition, a greater emphasis on the management of concomitant metabolic diseases and a collaborative effort is required to explore the complex pathophysiologic mechanisms underlying the disease.

Mortality Outcomes by Fibrosis Stage in Nonalcoholic Fatty Liver Disease: A Systematic Review and Meta-analysis.

BACKGROUND & AIMS: Fibrosis is a key determinant of clinical outcomes in nonalcoholic fatty liver disease (NAFLD), but time-dependent risk of mortality has not been reported in previous meta-analyses. We performed an updated time-to-event meta-analysis to provide robust estimates for all-cause and liver-related mortality in biopsy-confirmed NAFLD with comparisons between fibrosis stages. METHODS: Medline and Embase databases were searched to include cohort studies reporting survival outcomes by fibrosis stage in biopsy-proven NAFLD. Survival estimates were pooled using reconstructed individual participant data. Conventional meta-analysis was conducted to pool adjusted hazard ratios (HRs) using DerSimonian and Laird random effects model. RESULTS: A total of 14 articles involving 17,301 patients with NAFLD were included. All-cause mortality at 1, 5, and 10 years for stage 0 to 2 fibrosis was 0.1%, 3.3%, and 7.7% vs 0.3%, 20.6%, and 41.5% for stage 4 fibrosis. Compared with stage 0 fibrosis, all-cause mortality increased with fibrosis stage: stage 2; HR, 1.46 (95% confidence interval [CI], 1.08-1.98), stage 3; HR, 1.96 (95% CI, 1.41-2.72), and stage 4; HR, 3.66 (95% CI, 2.65-5.05). Risk for liver-related mortality increased exponentially as fibrosis stage increased: stage 2; HR, 4.07 (95% CI, 1.44-11.5), stage 3; HR, 7.59 (95% CI, 2.80-20.5), and stage 4; HR, 15.1 (95% CI, 5.27-43.4). Stage 3 to 4 fibrosis had a higher all-cause (HR, 3.32) and liver-related mortality (HR, 10.40) compared with stage 0 to 2 fibrosis, whereas stage 4 fibrosis had higher all-cause (HR, 2.67; 95% CI, 1.47-4.83) and liver-related mortality (HR, 2.57; 95% CI, 1.22-5.42) vs stage 3 fibrosis. CONCLUSIONS: Risk of all-cause and liver-related mortality increases substantially with fibrosis stage. These data have important implications for prognostication and trial design.
