Postoperative analgesic consumption for primary versus first repeat Cesarean delivery: a historical cohort study.

PURPOSE: It is unclear if postoperative pain experience and opioid consumption differ in patients undergoing primary vs repeat Cesarean delivery (CD) as prior studies have yielded conflicting results and none used the same patients as their own controls. We sought to compare opioid consumption and pain scores in patients undergoing both a primary and a first repeat CD, using the same patients as their own controls. METHODS: We conducted a single-centre historical cohort study of patients who underwent both a primary and a first repeat CD under neuraxial anesthesia between 1 January 2016 and 30 November 2022. The same standardized multimodal analgesic regimen was used for all patients. The primary outcome was opioid consumption in oral morphine equivalents (OME) at 48 hr after surgery. Secondary outcomes included area under the curve for pain scores at 24 and 48 hr, and opioid consumption at 24 hr. RESULTS: We included 409 patients. In unadjusted analysis, there were no significant differences between primary and repeat CD in median [interquartile range] opioid consumption at 48 hr (45 [15-89] mg vs 45 [15-83] mg OME) or in any of the secondary outcomes. In the multivariable model adjusting for age, body mass index, anxiety, depression, priority, surgery duration, gestational age, receipt of postoperative ketorolac, and neuraxial type, repeat CD was still not associated with increased opioid consumption compared with primary CD (adjusted rate ratio, 1.20; 95% confidence interval, 0.95 to 1.51). CONCLUSION: In this retrospective study, we found no differences in postoperative opioid consumption or reported pain scores in patients who underwent both a primary and a first repeat CD.

RéSUMé: OBJECTIF: Nous ne savons pas si l'expérience de la douleur postopératoire et la consommation d'opioïdes diffèrent chez la patientèle accouchant par césarienne pour la première fois ou pour la seconde fois. En effet, les études antérieures ont donné des résultats contradictoires et aucune n'a utilisé la même patientèle comme témoins. Nous avons cherché à comparer la consommation d'opioïdes et les scores de douleur chez les personnes parturientes exposées à la fois à un premier puis un deuxième accouchement par césarienne en recrutant les mêmes personnes en tant que leurs propres témoins. MéTHODE: Nous avons mené une étude de cohorte historique monocentrique auprès de personnes parturientes ayant subi à la fois une première et une seconde césarienne sous anesthésie neuraxiale entre le 1er janvier 2016 et le 30 novembre 2022. Le même régime analgésique multimodal standardisé a été utilisé pour toutes les personnes dans l'étude. Le critère d'évaluation principal était la consommation d'opioïdes en équivalents morphine oraux (EMO) 48 heures après la chirurgie. Les critères d'évaluation secondaires comprenaient la surface sous la courbe pour les scores de douleur à 24 et 48 heures, et la consommation d'opioïdes à 24 heures. RéSULTATS: Nous avons inclus 409 personnes. Dans l'analyse non ajustée, il n'y avait pas de différence significative entre le premier et le deuxième accouchement par césarienne en ce qui concerne la consommation médiane d'opioïdes [écart interquartile] à 48 heures (45 [15 à 89] mg vs 45 [15­83] mg EMO) ou dans l'un des critères d'évaluation secondaires. Dans le modèle multivarié ajusté en fonction de l'âge, l'indice de masse corporelle, l'anxiété, la dépression, la priorité, la durée de la chirurgie, l'âge gestationnel, l'administration de kétorolac postopératoire et le type d'anesthésie neuraxiale, une deuxième césarienne n'était toujours pas associée à une consommation accrue d'opioïdes par rapport à une première césarienne (rapport de taux ajusté, 1,20; intervalle de confiance à 95 %, 0,95 à 1,51). CONCLUSION: Dans cette étude rétrospective, nous n'avons trouvé aucune différence dans la consommation d'opioïdes postopératoires ou les scores de douleur rapportés chez la patientèle ayant accouché par césarienne pour la première ou pour la deuxième fois.

Trends in the Utilization of Multiorgan Support Among Adults Undergoing High-risk Cardiac Surgery in the United States.

OBJECTIVES: To examine trends in the prevalence of multiorgan dysfunction (MODS), utilization of multi-organ support (MOS), and mortality among patients undergoing cardiac surgery with MODS who received MOS in the United States. DESIGN: Retrospective cohort study. SETTING: 183 hospitals in the Premier Healthcare Database. PARTICIPANTS: Adults ≥18 years old undergoing high-risk elective or non-elective cardiac surgery. INTERVENTIONS: none. MEASUREMENTS AND MAIN RESULTS: The exposure was time (consecutive calendar quarters) January 2008 and June 2018. We analyzed hospital data using day-stamped hospital billing codes and diagnosis and procedure codes to assess MODS prevalence, MOS utilization, and mortality. Among 129,102 elective and 136,190 non-elective high-risk cardiac surgical cases across 183 hospitals, 10,001 (7.7%) and 21,556 (15.8%) of patients developed MODS, respectively. Among patients who experienced MODS, 2,181 (22%) of elective and 5,425 (25%) of non-elective cardiac surgical cases utilized MOS. From 2008-2018, MODS increased in both high-risk elective and non-elective cardiac surgical cases. Similarly, MOS increased in both high-risk elective and non-elective cardiac surgical cases. As a component of MOS, mechanical circulatory support (MCS) increased over time. Over the study period, risk-adjusted mortality, in patients who developed MODS receiving MOS, increased in high-risk non-elective cardiac surgery and decreased in high-risk elective cardiac surgery, despite increasing MODS prevalence and MOS utilization (p<0.001). CONCLUSIONS: Among patients undergoing high-risk cardiac surgery in the United States, MODS prevalence and MOS utilization (including MCS) increased over time. Risk-adjusted mortality trends differed in elective and non-elective cardiac surgery. Further research is necessary to optimize outcomes among patients undergoing high-risk cardiac surgery.

Use of Early Ketamine Sedation and Association With Clinical and Cost Outcomes Among Mechanically Ventilated Patients With COVID-19: A Retrospective Cohort Study.

OBJECTIVES: To describe the utilization of early ketamine use among patients mechanically ventilated for COVID-19, and examine associations with in-hospital mortality and other clinical outcomes. DESIGN: Retrospective cohort study. SETTING: Six hundred ten hospitals contributing data to the Premier Healthcare Database between April 2020 and June 2021. PATIENTS: Adults with COVID-19 and greater than or equal to 2 consecutive days of mechanical ventilation within 5 days of hospitalization. INTERVENTION: The exposures were early ketamine use initiated within 2 days of intubation and continued for greater than 1 day. MEASUREMENTS: Primary was hospital mortality. Secondary outcomes included length of stay (LOS) in the hospital and ICUs, ventilator days, vasopressor days, renal replacement therapy (RRT), and total hospital cost. The propensity score matching analysis was used to adjust for confounders. MAIN RESULTS: Among 42,954 patients, 1,423 (3.3%) were exposed to early ketamine use. After propensity score matching including 1,390 patients in each group, recipients of ketamine infusions were associated with higher hospital mortality (52.5% vs. 45.9%, risk ratio: 1.14, [1.06-1.23]), longer median ICU stay (13 vs. 12 d, mean ratio [MR]: 1.15 [1.08-1.23]), and longer ventilator days (12 vs. 11 d, MR: 1.19 [1.12-1.27]). There were no associations for hospital LOS (17 [10-27] vs. 17 [9-28], MR: 1.05 [0.99-1.12]), vasopressor days (4 vs. 4, MR: 1.04 [0.95-1.14]), and RRT (22.9% vs. 21.7%, RR: 1.05 [0.92-1.21]). Total hospital cost was higher (median $72,481 vs. $65,584, MR: 1.11 [1.05-1.19]). CONCLUSIONS: In a diverse sample of U.S. hospitals, about one in 30 patients mechanically ventilated with COVID-19 received ketamine infusions. Early ketamine may have an association with higher hospital mortality, increased total cost, ICU stay, and ventilator days, but no associations for hospital LOS, vasopressor days, and RRT. However, confounding by the severity of illness might occur due to higher extracorporeal membrane oxygenation and RRT use in the ketamine group. Further randomized trials are needed to better understand the role of ketamine infusions in the management of critically ill patients.

The 90% effective dose of intrathecal hyperbaric bupivacaine for Cesarean delivery under combined spinal-epidural anesthesia in parturients with super obesity: an up-down sequential allocation study.

PURPOSE: To determine the 90% effective dose (ED90) of intrathecal hyperbaric bupivacaine for Cesarean delivery under combined spinal-epidural anesthesia (CSE) in parturients with super obesity (body mass index [BMI] ≥ 50 kg·m-2). METHODS: We enrolled parturients with BMI ≥ 50 kg·m-2 with term, singleton vertex pregnancies undergoing elective Cesarean delivery under CSE. An independent statistician generated the 0.75% hyperbaric bupivacaine dosing regimen in increments of 0.75 mg using a biased-coin up-down sequential allocation technique. This was combined with 15 µg fentanyl, 150 µg morphine, and normal saline to a volume of 2.05 mL. The initial and maximum doses were 9.75 mg and 12 mg, respectively. Participants, clinical team, and outcome assessors were blinded to the dose. The primary outcome was block success, defined as T6 block to pinprick within ten minutes and no intraoperative analgesic supplementation within 90 min of spinal injection. We determined the ED90 using logistic regression. RESULTS: We enrolled 45 parturients and included 42 in the analysis. All doses achieved a T6 level within ten minutes, and the primary outcome occurred in 0/1 (0%) of the 9.75-mg doses, 2/3 (67%) of the 10.5-mg doses, 21/27 (78%) of the 11.25-mg doses, and 11/11 (100%) of the 12-mg doses. The ED90 of hyperbaric bupivacaine was 11.56 mg (95% confidence interval, 11.16 to 11.99). Four parturients (9.5%) had sensory level higher than T2, but none was symptomatic or required general anesthesia. CONCLUSION: The estimated ED90 of hyperbaric bupivacaine with fentanyl and morphine in parturients with super obesity undergoing Cesarean delivery under CSE was approximately 11.5 mg. STUDY REGISTRATION: ClinicalTrials.gov (NCT03781388); first submitted 18 December 2018.

RéSUMé: OBJECTIF: Notre objectif était de déterminer la dose efficace à 90 % (DE90) de bupivacaïne hyperbare intrathécale pour l'accouchement par césarienne sous péri-rachianesthésie combinée (PRC) chez les personnes parturientes atteintes de super obésité (indice de masse corporelle [IMC] ≥ 50 kg·m−2). MéTHODE: Nous avons recruté des personnes parturientes ayant un IMC ≥ 50 kg·m−2 présentant des grossesses uniques à terme, en présentation céphalique et bénéficiant d'un accouchement par césarienne programmée sous PRC. Un·e statisticien·ne indépendant·e a généré le schéma posologique de bupivacaïne hyperbare à 0,75 % par incréments de 0,75 mg à l'aide d'une technique d'allocation séquentielle en escalier. La bupivacaïne a été combinée à 15 µg de fentanyl, 150 µg de morphine et à une solution physiologique salée jusqu'à un volume de 2,05 mL. Les doses initiale et maximale étaient respectivement de 9,75 mg et 12 mg. Les participant·es, l'équipe clinique et les personnes évaluant les résultats n'avaient pas connaissance de la dose. Le critère d'évaluation principal était la réussite du bloc, définie comme un bloc à T6 à la piqûre dans les dix minutes et aucune supplémentation analgésique peropératoire dans les 90 minutes suivant l'injection rachidienne. Nous avons déterminé la DE90 à l'aide d'une méthode de régression logistique. RéSULTATS: Nous avons recruté 45 personnes parturientes et en avons inclus 42 dans l'analyse. Toutes les doses ont atteint le niveau T6 en dix minutes, et le critère d'évaluation principal a été obtenu pour 0/1 (0 %) des doses de 9,75 mg, 2/3 (67 %) des doses de 10,5 mg, 21/27 (78 %) des doses de 11,25 mg et 11/11 (100 %) des doses de 12 mg. La DE90 de bupivacaïne hyperbare était de 11,56 mg (intervalle de confiance à 95 %, 11,16 à 11,99). Quatre personnes parturientes (9,5 %) ont affiché un niveau sensoriel supérieur à T2, mais aucune n'était symptomatique ni n'a nécessité d'anesthésie générale. CONCLUSION: La DE90 estimée de bupivacaïne hyperbare avec fentanyl et morphine chez les personnes parturientes hyperobèses bénéficiant d'une césarienne sous PRC était d'environ 11,5 mg.

Hospital Discharge Codes and Overestimating Severe Maternal Morbidity During Delivery Hospitalization.

Our objective was to identify birth hospitalization severe maternal morbidity (SMM) diagnoses that were also coded during prior encounters and, thus, potentially falsely carried forward as de novo SMM events. This retrospective cohort study included pregnant patients with births between 2016 and 2020. We applied the SMM algorithm to the birth hospitalization and encounters occurring prepregnancy, antepartum, and postpartum. The primary outcome was the rate of SMM diagnoses recorded during the birth hospitalization that were also coded on previous encounters. There were 1,380 (1.8%) birthing patients with SMM. Of patients with SMM codes at the birth hospitalization, 19.0% had the same SMM code during a prior encounter. Certain SMM events may be prone to carry-forward errors and may not signify a de novo birth hospitalization event.

The Management of Posttraumatic Stress Disorder and Acute Stress Disorder: Synopsis of the 2023 U.S. Department of Veterans Affairs and U.S. Department of Defense Clinical Practice Guideline.

DESCRIPTION: The U.S. Department of Veterans Affairs (VA) and Department of Defense (DoD) worked together to revise the 2017 VA/DoD Clinical Practice Guideline for the Management of Posttraumatic Stress Disorder and Acute Stress Disorder. This article summarizes the 2023 clinical practice guideline (CPG) and its development process, focusing on assessments and treatments for which evidence was sufficient to support a recommendation for or against. METHODS: Subject experts from both departments developed 12 key questions and reviewed the published literature after a systematic search using the PICOTS (population, intervention, comparator, outcomes, timing of outcomes measurement, and setting) method. The evidence was then evaluated using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) method. Recommendations were made after consensus was reached; they were based on quality and strength of evidence and informed by other factors, including feasibility and patient perspectives. Once the draft was peer reviewed by an external group of experts and their inputs were incorporated, the final document was completed. RECOMMENDATIONS: The revised CPG includes 34 recommendations in the following 5 topic areas: assessment and diagnosis, prevention, treatment, treatment of nightmares, and treatment of posttraumatic stress disorder (PTSD) with co-occurring conditions. Six recommendations on PTSD treatment were rated as strong. The CPG recommends use of specific manualized psychotherapies over pharmacotherapy; prolonged exposure, cognitive processing therapy, or eye movement desensitization and reprocessing psychotherapy; paroxetine, sertraline, or venlafaxine; and secure video teleconferencing to deliver recommended psychotherapy when that therapy has been validated for use with video teleconferencing or when other options are unavailable. The CPG also recommends against use of benzodiazepines, cannabis, or cannabis-derived products. Providers are encouraged to use this guideline to support evidence-based, patient-centered care and shared decision making to optimize individuals' health outcomes and quality of life.

Spatial and Temporal Variability in Stream Thermal Regime Drivers for Three River Networks During the Summer Growing Season.

Many cold-water dependent aquatic organisms are experiencing habitat and population declines from increasing water temperatures. Identifying mechanisms which drive local and regional stream thermal regimes facilitates restoration at ecologically relevant scales. Stream temperatures vary spatially and temporally both within and among river basins. We developed a modeling process to identify statistical relationships between drivers of stream temperature and covariates representing landscape, climate, and management-related processes. The modeling process was tested in 3 study areas of the Pacific Northwest USA during the growing season (May [start], August [warmest], September [end]). Across all months and study systems, covariates with the highest relative importance represented the physical landscape (elevation [1st], catchment area [3rd], main channel slope [5th]) and climate covariates (mean monthly air temperature [2nd] and discharge [4th]). Two management covariates (ground water use [6th] and riparian shade [7th]) also had high relative importance. Across the growing season (for all basins) local reach slope had high relative importance in May, but transitioned to a regional main channel slope covariate in August and September. This modeling process identified regionally similar and locally unique relationships among drivers of stream temperature. High relative importance of management-related covariates suggested potential restoration actions for each system.

School Safety and Mental Health Awareness: Recommendations from K-12 Texas Public School Teachers.

BACKGROUND: Mass school shootings have created fear in the American public. The results of this fear have been the hardening of schools, lockdowns, and active shooter drills, yet the mass shootings have not ended. The goal of this study was to analyze the mental health awareness of K-12 public schools teachers in Texas with a goal to identify the connections between mental health awareness and school safety. METHODS: Data were used from an archival database of K-12 teacher responses in the 2020 Texas Educators' Needs Assessment Regarding School Safety and Victims Services to assess the current state of student mental health concerns and the connection of these concerns to school safety. This needs assessment included one mixed methods survey that was collected from Texas K-12 educators and Texas educators working in higher education in 2020. The original study included 25,161 usable responses (6.1%). For the purpose of this study, only K-12 teacher responses were used in the analysis. The K-12 teacher participants (n = 19,888) included the following institutional levels: (a) special setting, 2,919 (14.7%); (b) elementary school, 6,813 (34.3%); (c) middle/intermediate school, 4,189 (21.1%); (d) high school, 5,864 (29.5%); and (e) district level, 103 (0.5%). A total of 8,053 participant's qualitative responses and 10 of the original quantitative survey questions from the archival data were used to identify all findings in the study. RESULTS: Collected qualitative and quantitative participant responses' outlined a need to improve student mental health by strengthening the focus on supporting all stakeholders (e.g., teachers, parents, counselors, and students) in mental health awareness and education. Participant comments focused on the lack of training, counselor support, and community support regarding the mental health needs of their students. CONCLUSION: Recommendations to improve student mental health that were developed from this study identified key goals in school counselor role and responsibility to student mental health, increased involvement of community agencies, and improvement to in-school mental health counseling. Final recommendations of this study were focused on the need to improve student mental health if stakeholders want to develop a positive school environment. The failure to build an environment that is focused on student mental health will continue to affect the goal to improve overall school safety.

Maternal Morbidity According to Mode of Delivery Among Pregnant Patients With Pulmonary Hypertension.

BACKGROUND: Patients with pulmonary hypertension have a high risk of maternal morbidity and mortality. It is unknown if a trial of labor carries a lower risk of morbidity in these patients compared to a planned cesarean delivery. The objective of this study was to examine the association of delivery mode with severe maternal morbidity events during delivery hospitalization among patients with pulmonary hypertension. METHODS: This retrospective cohort study used the Premier inpatient administrative database. Patients delivering ≥25 weeks gestation from January 1, 2016, to September 30, 2020, and with pulmonary hypertension were included. The primary analysis compared intended vaginal delivery (ie, trial of labor) to intended cesarean delivery (intention to treat analysis). A sensitivity analysis was conducted comparing vaginal delivery to cesarean delivery (as treated analysis). The primary outcome was nontransfusion severe maternal morbidity during the delivery hospitalization. Secondary outcomes included blood transfusion (4 or more units) and readmission to the delivery hospital within 90 days from discharge from delivery hospitalization. RESULTS: The cohort consisted of 727 deliveries. In the primary analysis, there was no difference in nontransfusion morbidity between intended vaginal delivery and intended cesarean delivery groups (adjusted odds ratio [aOR], 0.75; 95% confidence interval [CI], 0.49-1.15). In secondary analyses, intended cesarean delivery was not associated with blood transfusion (aOR, 0.71; 95% CI, 0.34-1.50) or readmission within 90 days (aOR, 0.60; 95% CI, 0.32-1.14). In the sensitivity analysis, cesarean delivery was associated with a 3-fold higher risk of nontransfusion morbidity compared to vaginal delivery (aOR, 2.64; 95% CI, 1.54-3.93), a 3-fold higher risk of blood transfusion (aOR, 3.06; 95% CI, 1.17-7.99), and a 2-fold higher risk of readmission within 90 days (aOR, 2.20; 95% CI, 1.09-4.46) compared to vaginal delivery. CONCLUSIONS: Among pregnant patients with pulmonary hypertension, a trial of labor was not associated with a higher risk of morbidity compared to an intended cesarean delivery. One-third of patients who required an intrapartum cesarean delivery had a morbidity event, demonstrating the increased risk of adverse events in this group.

Effectiveness of a bivalent mRNA vaccine dose against symptomatic SARS-CoV-2 infection among U.S. Healthcare personnel, September 2022-May 2023.

BACKGROUND: Bivalent mRNA vaccines were recommended since September 2022. However, coverage with a recent vaccine dose has been limited, and there are few robust estimates of bivalent VE against symptomatic SARS-CoV-2 infection (COVID-19). We estimated VE of a bivalent mRNA vaccine dose against COVID-19 among eligible U.S. healthcare personnel who had previously received monovalent mRNA vaccine doses. METHODS: We conducted a case-control study in 22 U.S. states, and enrolled healthcare personnel with COVID-19 (case-participants) or without COVID-19 (control-participants) during September 2022-May 2023. Participants were considered eligible for a bivalent mRNA dose if they had received 2-4 monovalent (ancestral-strain) mRNA vaccine doses, and were ≥67 days after the most recent vaccine dose. We estimated VE of a bivalent mRNA dose using conditional logistic regression, accounting for matching by region and four-week calendar period. We adjusted estimates for age group, sex, race and ethnicity, educational level, underlying health conditions, community COVID-19 exposure, prior SARS-CoV-2 infection, and days since the last monovalent mRNA dose. RESULTS: Among 3,647 healthcare personnel, 1,528 were included as case-participants and 2,119 as control-participants. Participants received their last monovalent mRNA dose a median of 404 days previously; 1,234 (33.8%) also received a bivalent mRNA dose a median of 93 days previously. Overall, VE of a bivalent dose was 34.1% (95% CI, 22.6%-43.9%) against COVID-19 and was similar by product, days since last monovalent dose, number of prior doses, age group, and presence of underlying health conditions. However, VE declined from 54.8% (95% CI, 40.7%-65.6%) after 7-59 days to 21.6% (95% CI 5.6%-34.9%) after ≥60 days. CONCLUSIONS: Bivalent mRNA COVID-19 vaccines initially conferred approximately 55% protection against COVID-19 among U.S. healthcare personnel. However, protection waned after two months. These findings indicate moderate initial protection against symptomatic SARS-CoV-2 infection by remaining up-to-date with COVID-19 vaccines.

Severe Maternal Morbidity According to Mode of Delivery Among Pregnant Patients With Cardiomyopathies.

BACKGROUND: Women with cardiomyopathies are at risk for pregnancy complications. The optimal mode of delivery in these patients is guided by expert opinion and limited small studies. OBJECTIVES: The objective of this study is to examine the association of delivery mode with severe maternal morbidity events during delivery hospitalization and readmissions among patients with cardiomyopathies. METHODS: The Premier inpatient administrative database was used to conduct a retrospective cohort study of pregnant patients with a diagnosis of a cardiomyopathy. Utilizing a target trial emulation strategy, the primary analysis compared outcomes among patients exposed to intended vaginal delivery vs intended cesarean delivery (intention to treat). A secondary analysis compared outcomes among patients who delivered vaginally vs by cesarean (as-treated). Outcomes examined were nontransfusion severe maternal morbidity during the delivery hospitalization, blood transfusion, and readmission. RESULTS: The cohort consisted of 2,921 deliveries. In the primary analysis (intention to treat), there was no difference in nontransfusion morbidity (adjusted OR [aOR]: 1.17; 95% CI: 0.91-1.51), blood transfusion (aOR: 1.27; 95% CI: 0.81-1.98), or readmission (aOR: 1.03; 95% CI: 0.73-1.44) between intended vaginal delivery and intended cesarean delivery. In the as-treated analysis, cesarean delivery was associated with a 2-fold higher risk of nontransfusion morbidity (aOR: 2.44; 95% CI: 1.85-3.22) and blood transfusion (aOR: 2.26; 95% CI: 1.34-3.81) when compared with vaginal delivery. CONCLUSIONS: In patients with cardiomyopathies, a trial of labor does not confer a higher risk of maternal morbidity, blood transfusion, or readmission compared with planned cesarean delivery.

Development and implementation barriers of a new patient-reported measure: The Radiation therapy-related Inconvenience Questionnaire (RIQ).

INTRODUCTION: Radiation therapy (RT) can benefit approximately 50% of cancer patients and contribute to 40% of all cancer cures, yet its utilisation in cancer is low globally. Several factors contribute to this including perceived inconvenience related to accessing and utilising RT. To quantitatively assess the latter, a new tool - the Radiation therapy-related Inconvenience Questionnaire (RIQ) - was developed. This study aimed to pre-test the RIQ and explore barriers and facilitators to implementing it in routine clinical practice and clinical trials. METHODS: Semi-structured cognitive interviews were conducted with patients undertaking RT, recruited via three hospitals to examine content validity, acceptability, and comprehensibility of the RIQ. Interviews identified inconsistencies, relevance, and clarity of items. Semi-structured interviews with healthcare professionals involved in the delivery of care to individuals undertaking RT explored barriers and facilitators to routine usage. Thematic analysis was used to identify themes. RESULTS: Patients (N = 15) identified problems in content, instructions, layout, length, and response options; consequently, 25 items were revised and eight removed, resulting in a final 29-item questionnaire. Clinicians identified staff- and patient-specific barriers to implementing RIQ in clinical practice. Perceived facilitators included the following: (a) workplace factors, (b) mode of administration, and (c) imparting knowledge. CONCLUSION: This study demonstrated acceptability and comprehensibility of the 29-item RIQ amongst cancer patients undertaking RT and treating clinicians. The next phase will evaluate the RIQ's measurement properties in a larger clinical study. The barriers and facilitators identified can guide future implementation of RIQ in clinical practice and clinical trials.

A multidisciplinary opioid-reduction pathway for robotic prostatectomy: outcomes at year one.

BACKGROUND: Opioid use has come under increasing scrutiny, driven in part by the opioid crisis and growing concerns that up to 6% of opioid-naïve patients may become chronic opioid users. This has resulted in a revaluation of perioperative practice. For this reason, we implemented a multidisciplinary pathway to reduce perioperative opioid usage through education and standardization of practice. METHODS: A single-centre retrospective evaluation was performed after 1 year, comparing the outcomes to those of the 2 years prior to pathway implementation. Comparisons were made between pre- vs. post pathway change by 2:1 propensity matching between cohorts. Univariate linear regression models were created using demographic variables with those that were p < 0.15 included in the final model and using post-operative opioid use (in oral morphine equivalents, OME) as the primary outcome. RESULTS: We found that intraoperative opioid use was significantly decreased 38.2 mg (28.3) vs. 18.0 mg (40.4) oral morphine equivalents (OME), p < .001, as was post-operative opioid use for the duration of the hospitalization, 46.3 mg (49.5) vs. 35.49 mg (43.7) OME, p = 0.002. In subgroup analysis of those that received some intraoperative opioids (n = 152) and those that received no opioids (n = 34), we found that both groups required fewer opioids in the post-operative period 47.0 mg (47.7) vs. 32.4 mg (40.6) OME, p = 0.001, + intraoperative opioids, 62.4 mg (62.9) vs. 35.8 mg (27.7) OME, p = 0.13, - intraoperative opioids. Time to discharge from the PACU was reduced in both groups 215 min (199) vs. 167 min (122), p < 0.003, + intraoperative opioids and 253 min (270) vs. 167 min (105), p = 0.028, - intraoperative opioids. The duration of time until meeting discharge criteria from PACU was 221 min (205) vs. 170 min (120), p = 0.001. Hospital length of stay (LOS) was significantly reduced 1.4 days (1.3) vs. 1.2 days (0.8), p = 0.005. Both sub-groups demonstrated reduced hospital LOS 1.5 days (1.4) vs. 1.2 days (0.8), p = 0.0047, + intraoperative opioids and 1.7 days (1.6) vs. 1.3 days (0.9), p = 0.0583, - intraoperative opioids. Average pain scores during PACU admission and post-PACU until discharge were not statistically different between cohorts. CONCLUSIONS: These findings underscore the effectiveness of a multidisciplinary approach to reduce opioids. Furthermore, it demonstrates improved patient outcomes as measured by both shorter PACU and almost 50% reduction in perioperative opioid use whilst maintaining similar analgesia as indicated by patient-reported pain scores.

Procalcitonin levels in pregnancy: A systematic review and meta-analysis of observational studies.

BACKGROUND: The utility of procalcitonin to identify obstetric sepsis is unknown. OBJECTIVE: To calculate the mean (range) procalcitonin in pregnancy among healthy women not in labor (group 1), healthy women in labor (group 2), and women with preterm prelabor rupture of membranes (PPROM) without clinical chorioamnionitis (group 3). SEARCH STRATEGY: NLM PubMed, Elsevier Embase, and Wiley Cochrane Central Register of Controlled Trials from inception to February 21, 2022. SELECTION CRITERIA: Ten or more pregnant women with procalcitonin reported at more than 20 weeks of pregnancy, with information on labor, PPROM, and infection. Exclusions were major medical comorbidities. DATA COLLECTION AND ANALYSIS: Each abstract and full-text review was independently reviewed by the same two authors. Quality was reviewed using the Newcastle-Ottawa Scale. A meta-analysis was performed using a random effects model. MAIN RESULTS: The systematic review included 25 studies: 10 (40%) of good quality and 15 (60%) of poor quality. The meta-analysis included 21 studies. Mean procalcitonin in group 1 was 0.092 ng/mL (range 0.036-0.049 ng/mL), in group 2 it was 0.130 ng/mL (range 0.049-0.259 ng/mL), and in group 3 it was 0.345 ng/mL (range 0.005-1.292 ng/mL). CONCLUSIONS: Among healthy pregnant women not in labor, procalcitonin levels are comparable to those in non-pregnant adults and may be useful in identifying infection. Procalcitonin levels in other groups overlap abnormal values of procalcitonin in non-pregnant adults, and may not discriminate infection among women in labor or with obstetric comorbidities.

Opioid-Sparing Multimodal Analgesia Use After Cesarean Delivery Under General Anesthesia: A Retrospective Cohort Study in 729 US Hospitals.

BACKGROUND: Optimizing analgesia after cesarean delivery is essential to quality of patient recovery. The American Society of Anesthesiologists and the Society for Obstetric Anesthesia and Perinatology recommend multimodal analgesia (MMA). However, little is known about clinical implementation of these guidelines after cesarean delivery under general anesthesia (GA). We performed this study to describe the use of MMA after cesarean delivery under GA in the United States and determine factors associated with use of MMA, variation in analgesia practice across hospitals, and trends in MMA use over time. METHODS: A retrospective cohort study of women over 18 years who had a cesarean delivery under GA between 2008 and 2018 was conducted using the Premier Healthcare database (Premier Inc). The primary outcome was utilization of opioid-sparing MMA (osMMA), defined as receipt of nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen with or without opioids and without the use of an opioid-combination drug. Any use of either agent within a combination preparation was not considered osMMA. The secondary outcome was use of optimal opioid-sparing MMA (OosMMA), defined as use of a local anesthetic technique such as truncal block or local anesthetic infiltration in addition to osMMA. Mixed-effects logistic regression models were used to examine factors associated with use of osMMA, as well as variation across hospitals. RESULTS: A total of 130,946 patients were included in analysis. osMMA regimens were used in 11,133 patients (8.5%). Use of osMMA increased from 2.0% in 2008 to 18.8% in 2018. Black race (7.9% vs 9.3%; odds ratio [OR] [95% confidence interval {CI}] 0.87 [0.81-0.94]) and Hispanic ethnicity (8.6% vs 10.0%; OR, 0.86 [0.79-0.950]) were associated with less receipt of osMMA compared to White and non-Hispanic counterparts. Medical comorbidities were generally not associated with receipt of osMMA, although patients with preeclampsia were less likely to receive osMMA (9.0%; OR, 0.91 [0.85-0.98]), while those with a history of drug abuse (12.5%; OR, 1.42 [1.27-1.58]) were more likely to receive osMMA. There was moderate interhospital variability in the use of osMMA (intraclass correlation coefficient = 38%). OosMMA was used in 2122 (1.6%) patients, and utilization increased from 0.8% in 2008 to 4.1% in 2018. CONCLUSIONS: Variation in osMMA utilization was observed after cesarean delivery under GA in this cohort of US hospitals. While increasing trends in utilization of osMMA and OosMMA are encouraging, there is need for increased attention to postoperative analgesia practices after GA for cesarean delivery given low percentage of patients receiving osMMA and OosMMA.

Maternal Cardiovascular Morbidity Events Following Preeclampsia: A Retrospective Cohort Study.

BACKGROUND: Patients with preeclampsia are at high risk for long-term cardiovascular events, yet the short-term, acute cardiovascular complications that follow preeclampsia are understudied. The objective of this study was to compare the short-term, acute maternal cardiovascular morbidity events after delivery among patients with a diagnosis of preeclampsia versus those without this diagnosis. METHODS: In this retrospective cohort study, the Premier inpatient database was used to examine a cohort of obstetric patients older than 18 years, who delivered from January 1, 2016, to September 30, 2020. A diagnosis of preeclampsia and preeclampsia with severe features during delivery hospitalization were the exposures of interest. The primary outcome was a composite of maternal cardiovascular morbidity events during delivery hospital admission. The secondary outcome was the occurrence of maternal cardiovascular morbidity events during a readmission within 90 days of delivery hospitalization. RESULTS: In total, 4,488,759 patients met inclusion criteria, of which 158,114 (3.5%) were diagnosed with preeclampsia without severe features, and 117,940 (2.6%) with preeclampsia with severe features. Adjusted odds of maternal cardiovascular morbidity events were higher in patients with preeclampsia and in those with preeclampsia with severe features compared with those without preeclampsia during delivery hospitalization (adjusted odds ratio [OR] [95% confidence interval {CI}] 1.87 [1.78-1.97] and 4.74 [4.44-5.05], respectively) and within 90 days (adjusted OR [95% CI] 2.01 [1.83-2.21] and 2.32 [2.10-2.57], respectively). CONCLUSIONS: Patients with both preeclampsia and preeclampsia with severe features have higher rates of maternal cardiovascular morbidity events than those without preeclampsia. Future studies are necessary to examine which patients with preeclampsia are at highest risk for cardiovascular complications.

Incidence of Postreperfusion Hyperfibrinolysis in Liver Transplantation by Donor Type and Observed Treatment Strategies.

BACKGROUND: Hyperfibrinolysis is a possible complication during liver transplantation, particularly immediately after reperfusion. METHODS: We performed a retrospective study to examine the incidence, treatment, and resolution of postreperfusion hyperfibrinolysis in patients undergoing liver transplantation at Duke University Hospital from 2015 to 2020. RESULTS: Out of 535 patients undergoing liver transplantation, 21 or 3.9%, 95% CI (2.5-5.9), had hyperfibrinolysis after reperfusion. Hyperfibrinolysis occurred in 16 of 511 (3.1%) patients receiving livers from DBD donors, 5 of 18 (27.8%) patients receiving livers from donation after circulatory death (DCD) donors, and 0 of 6 (0.0%) patients receiving livers from living donors. Fibrinolysis was treated with cryoprecipitate (12/21), a combination of cryoprecipitate and tranexamic acid (3/21), or neither (6/21) and resolved within several hours in all cases. CONCLUSIONS: Anesthesiologists should be aware of the possibility of postreperfusion hyperfibrinolysis in liver transplantation, particularly with DCD donors, and may consider treatment with cryoprecipitate or tranexamic acid. Further work is needed to identify any potential differences, such as faster resolution of fibrinolysis, between different treatment modalities.

Complementary Approaches for Military Women with Chronic Pelvic Pain: A Randomized Trial.

Introduction: Active duty (AD) women suffer with chronic pelvic pain (CPP) while providers tackle diagnoses and treatments to keep them functional without contributing to the opioid epidemic. The purpose of this randomized trial was to determine the effectiveness of noninvasive, self-explanatory mindfulness-based stress reduction (MBSR) or self-paced healthy lifestyle (HL) interventions on CPP in AD women. Methods: A 6-week, interventional prospective study with AD women aged 21-55 years at Mountain Home (MTHM), Idaho, was conducted. Women were randomly assigned to MBSR (N = 21) or HL (N = 20) interventions. The primary outcome was pain perception. The secondary outcomes were depression and circulating cytokine levels. Results: Women in the MBSR group exhibited reduced pain interference (p < 0.01) and depression (p < 0.05) alongside decreased interleukin (IL)-4 (p < 0.05), IL-6 (p < 0.05), eotaxin (p < 0.05), monocyte chemoattractant protein-1 (p = 0.06), and interleukin-1 receptor antagonist (IL-1ra) (p < 0.01) and increased vascular endothelial growth factor (p < 0.05). Women in the HL group did not have changes in pain; however, they did exhibit reduced depression (p < 0.05) alongside decreased granulocyte-macrophage colony-stimulating factor (p < 0.05) and increased tumor necrosis factor alpha (p < 0.05), stromal cell-derived factor-1 (p < 0.01), and IL-1ra (p < 0.01). Conclusions: AD women receiving MBSR or HL had reduced depression scores and altered circulating cytokine levels; however, only those receiving MBSR had reduced pain perception. Findings support MBSR as an effective and viable behavioral treatment for AD women suffering from CPP and provide premise for larger randomized controlled studies.

Postoperative Acute Kidney Injury by Age and Sex: A Retrospective Cohort Association Study.

BACKGROUND: Acute kidney injury (AKI) after noncardiac surgery is common and has substantial health impact. Preclinical and clinical studies examining the influence of sex on AKI have yielded conflicting results, although they typically do not account for age-related changes. The objective of the study was to determine the association of age and sex groups on postoperative AKI. The authors hypothesized that younger females would display lower risk of postoperative AKI than males of similar age, and the protection would be lost in older females. METHODS: This was a multicenter retrospective cohort study across 46 institutions between 2013 and 2019. Participants included adult inpatients without pre-existing end-stage kidney disease undergoing index major noncardiac, nonkidney/urologic surgeries. The authors' primary exposure was age and sex groups defined as females 50 yr or younger, females older than 50 yr, males 50 yr or younger, and males older than 50 yr. The authors' primary outcome was development of AKI by Kidney Disease-Improving Global Outcomes serum creatinine criteria. Exploratory analyses included associations of ascending age groups and hormone replacement therapy home medications with postoperative AKI. RESULTS: Among 390,382 patients, 25,809 (6.6%) developed postoperative AKI (females 50 yr or younger: 2,190 of 58,585 [3.7%]; females older than 50 yr: 9,320 of 14,4047 [6.5%]; males 50 yr or younger: 3,289 of 55,503 [5.9%]; males older than 50 yr: 11,010 of 132,447 [8.3%]). When adjusted for AKI risk factors, compared to females younger than 50 yr (odds ratio, 1), the odds of AKI were higher in females older than 50 yr (odds ratio, 1.51; 95% CI, 1.43 to 1.59), males younger than 50 yr (odds ratio, 1.90; 95% CI, 1.79 to 2.01), and males older than 50 yr (odds ratio, 2.06; 95% CI, 1.96 to 2.17). CONCLUSIONS: Younger females display a lower odds of postoperative AKI that gradually increases with age. These results suggest that age-related changes in women should be further studied as modifiers of postoperative AKI risk after noncardiac surgery.
