RESUMO

PURPOSE: This review article is the first comprehensive evaluation of the available literature surrounding the education of death and dying in pharmacy schools. The purpose of this review was to describe the available literature and methods utilized regarding the emotional preparation for patient death in pharmacy education. PROCEDURES: Searches were performed in three pharmacy databases to identify articles that contained descriptions of activities related to death and dying education in pharmacy curriculums. FINDINGS: Eleven journal articles were reviewed, detailing activities in pharmacy education including simulations, didactic sessions, and an innovative "death over dessert" model. Evaluation methods varied, with surveys being most common, followed by reflection. Didactic courses demonstrated increased empathy and knowledge, while simulations compared to case-based activities improved skills, knowledge, and comfort levels with providing end-of-life care. Simulations often involved interprofessional groups, with third-year pharmacy students most evaluated. CONCLUSION: Pharmacy students were mainly exposed to death and dying scenarios through didactic courses or simulations, with limited longitudinal exposure. Research suggests that students may lack preparation for handling death-related situations, leading to trauma and dysfunction. While existing studies focus on outward effects like empathy, internal factors such as coping methods receive less attention. Unlike nursing and medicine literature, pharmacy education lacks comprehensive coverage of coping and emotional support strategies for death and dying scenarios. Additional focus should be placed on intentional incorporation of these topics into pharmacy curriculums.

RESUMO

Anodically coloring electrochromes have received attention in recent years as high-contrast alternatives to cathodically coloring electrochromes due to their superior optical contrast during electrochemical switching. While current systems represent significant progress for organic electrochromics, it is necessary to expand the structural diversity of these materials while simultaneously reducing the hazards associated with synthetic protocols. With these considerations in mind, a family of 1,4-dihydropyrrolo[3,2-b]pyrrole (DHPP) chromophores with varying functionalities along the 2,5-axis was envisioned to accomplish these goals. After predicting different absorbance traits as oxidized molecules with time-dependent density functional theory, DHPP chromophores with varying peripheral functionalities were synthesized in a single aerobic synthetic step via an iron-catalyzed multicomponent reaction and characterized as high-contrast chromophores. In solution, the DHPP chromophores absorb in the ultraviolet region of the electromagnetic spectrum, resulting in color-neutral L*a*b* color coordinates of ∼100, 0, 0. Upon chemical oxidation, each molecule transitions to absorb at various points across the visible spectrum based on the extent of electron-donating ability and can display five distinct colors. Importantly, the chromophores are redox-active and display switching capabilities with an applied electrochemical potential. In conjunction with building fundamental insights into molecular design of DHPP chromophores, the results and synthetic simplicity of DHPPs make them compelling materials for color-controlled high-contrast electrochromes.

RESUMO

Both endogenous antibodies and a subset of antibody therapeutics engage Fc gamma receptor (FcγR)IIIa / CD16a to stimulate a protective immune response. Increasing the FcγRIIIa/IgG1 interaction improves the immune response and thus represents a strategy to improve therapeutic efficacy. FcγRIIIa is a heavily glycosylated receptor and glycan composition affects antibody-binding affinity. Though our laboratory previously demonstrated that natural killer (NK) cell N-glycan composition affected the potency of one key protective mechanism, antibody-dependent cell-mediated cytotoxicity (ADCC), it was unclear if this effect was due to FcγRIIIa glycosylation. Furthermore, the structural mechanism linking glycan composition to affinity and cellular activation remained undescribed. To define the role of individual amino acid and N-glycan residues we measured affinity using multiple FcγRIIIa glycoforms. We observed stepwise affinity increases with each glycan truncation step with the most severely truncated glycoform displaying the highest affinity. Removing the N162 glycan demonstrated its predominant role in regulating antibody-binding affinity, in contrast to four other FcγRIIIa N-glycans. We next evaluated the impact of the N162 glycan on NK cell ADCC. NK cells expressing the FcγRIIIa V158 allotype exhibited increased ADCC following kifunensine treatment to limit N-glycan processing. Notably, an increase was not observed with cells expressing the FcγRIIIa V158 S164A variant that lacks N162 glycosylation, indicating the N162 glycan is required for increased NK cell ADCC. To gain structural insight into the mechanisms of N162 regulation, we applied a novel protein isotope labeling approach in combination with solution NMR spectroscopy. FG loop residues proximal to the N162 glycosylation site showed large chemical shift perturbations following glycan truncation. These data support a model for the regulation of FcγRIIIa affinity and NK cell ADCC whereby composition of the N162 glycan stabilizes the FG loop and thus the antibody-binding site.

RESUMO

Obesity is a major cause of metabolic dysfunction-associated steatohepatitis (MASH) and is characterized by inflammation and insulin resistance. Interferon-γ (IFNγ) is a pro-inflammatory cytokine elevated in obesity and modulating macrophage functions. Here, we show that male mice with loss of IFNγ signaling in myeloid cells (Lyz-IFNγR2-/-) are protected from diet-induced insulin resistance despite fatty liver. Obesity-mediated liver inflammation is also attenuated with reduced interleukin (IL)-12, a cytokine primarily released by macrophages, and IL-12 treatment in vivo causes insulin resistance by impairing hepatic insulin signaling. Following MASH diets, Lyz-IFNγR2-/- mice are rescued from developing liver fibrosis, which is associated with reduced fibroblast growth factor (FGF) 21 levels. These results indicate critical roles for IFNγ signaling in macrophages and their release of IL-12 in modulating obesity-mediated insulin resistance and fatty liver progression to MASH. In this work, we identify the IFNγ-IL12 axis in regulating intercellular crosstalk in the liver and as potential therapeutic targets to treat MASH.

RESUMO

Challenges to recruitment of family caregivers exist and are amplified when consent must occur in the context of chaotic healthcare circumstances, such as the transition from hospital to home. The onset of the COVID-19 pandemic during our randomized controlled trial provided an opportunity for a natural experiment exploring and examining different consent processes for caregiver recruitment. The purpose of this publication is to describe different recruitment processes (in-person versus virtual) and compare diversity in recruitment rates in the context of a care recipient's hospitalization. We found rates of family caregiver recruitment for in-person versus virtual were 28% and 23%, respectively (p = 0.01). Differences existed across groups with family caregivers recruited virtually being more likely to be younger, white, have greater than high school education, and not be a spouse or significant other to the care recipient, such as a child. Future work is still needed to identify the modality and timing of family caregiver recruitment to maximize rates and enhance the representativeness of the population for equitable impact.

RESUMO

Immunotherapy is a rapidly evolving field, with many models attempting to describe its impact on the immune system, especially when paired with radiotherapy. Tumor response to this combination involves a complex spatiotemporal dynamic which makes either clinical or pre-clinical in vivo investigation across the resulting extensive solution space extremely difficult. In this review, several in silico models of the interaction between radiotherapy, immunotherapy, and the patient's immune system are examined. The study included only mathematical models published in English that investigated the effects of radiotherapy on the immune system, or the effect of immuno-radiotherapy with immune checkpoint inhibitors. The findings indicate that treatment efficacy was predicted to improve when both radiotherapy and immunotherapy were administered, compared to radiotherapy or immunotherapy alone. However, the models do not agree on the optimal schedule and fractionation of radiotherapy and immunotherapy. This corresponds to relevant clinical trials, which report an improved treatment efficacy with combination therapy, however, the optimal scheduling varies between clinical trials. This discrepancy between the models can be attributed to the variation in model approach and the specific cancer types modeled, making the determination of the optimum general treatment schedule and model challenging. Further research needs to be conducted with similar data sets to evaluate the best model and treatment schedule for a specific cancer type and stage.

RESUMO

Background: People with HIV (PWH) who are coinfected with hepatitis B virus (HBV) have a higher risk of mortality compared with PWH alone. Populations such as people who inject drugs (PWID) and men who have sex with men (MSM) are particularly at high risk for HBV acquisition; yet, limited epidemiological data from these populations exist on HBV prevalence from low- and middle-income country settings (LMICs). Methods: We characterized the prevalence and correlates of HBV serological markers in a sample of PWID and MSM with HIV recruited across 15 Indian cities using hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), and hepatitis B surface antibody (anti-HBs). Testing of stored specimens for the presence of these markers was performed on the Abbott ARCHITECT i1000 as per the manufacturer's instructions. Correlates of ever being infected with HBV (reactive for anti-HBc and/or HBsAg) and chronic HBV (reactive for HBsAg) among those ever infected were assessed using univariable and multivariable multilevel logistic regression models accounting for site-level clustering. Results: A total of 2198 (95%) of the 2314 participants recruited for the trial were screened for HBV markers. The median age among the PWID and MSM participants was 30 and 32 years, respectively. The prevalence of ever being infected with HBV was 75.6% vs 46.9% in PWID vs MSM, respectively (P < .01); prevalence of chronic infection was also higher in PWID vs MSM (14.1% vs 9.5%; P < .01). Correlates of ever being infected with HBV among PWID included unstable housing (adjusted odds ratio [aOR], 5.02) and sharing injection paraphernalia (aOR, 2.70), and among MSM, correlates included history of injection drug use (aOR, 4.87) and gender identity. The prevalence of isolated core (anti-HBc in the absence of anti-HBs) was 34.7% vs 29.4% in PWID vs MSM (P < .05). Vaccination serostatus was <10% in both populations. Conclusions: In this large sample of PWID and MSM with HIV, we observed a high prevalence of serology consistent with HBV infection and low vaccination, highlighting the need for routine screening and catch-up vaccination. The high prevalence of isolated anti-HBc reactivity highlights the need to understand the risk of reactivation with this serological pattern.

RESUMO

Previable and periviable preterm prelabor rupture of membranes are challenging obstetric complications to manage, given the substantial risk of maternal morbidity and mortality with no guarantee of fetal benefit. The following are Society for Maternal-Fetal Medicine recommendations for the management of previable and periviable preterm prelabor rupture of membranes prior to the period when a trial of neonatal resuscitation and intensive care would be considered appropriate by the healthcare team and desired by the patient: (1) we recommend that pregnant patients with previable and periviable preterm prelabor rupture of membranes receive individualized counseling about the maternal and fetal risks and benefits of both abortion care and expectant management to guide an informed decision. All patients with previable and periviable preterm prelabor rupture of membranes should be offered abortion care. Expectant management can also be offered in the absence of contraindications (GRADE 1C); (2) we recommend antibiotics for pregnant individuals who choose expectant management after preterm prelabor rupture of membranes at ≥ 24 0/7 weeks of gestation (GRADE 1B); (3) antibiotics can be considered after preterm prelabor rupture of membranes at 20 0/7 to 23 6/7 weeks of gestation (GRADE 2C); (4) administration of antenatal corticosteroids and magnesium are not recommended until the time when a trial of neonatal resuscitation and intensive care would be considered appropriate by the healthcare team and desired by the patient (GRADE 1B); (5) serial amnioinfusions and amniopatch are considered investigational and should be used only in a clinical trial setting; they are not recommended for routine care of previable and periviable preterm prelabor rupture of membranes (GRADE 1B); (6) cerclage management after preterm prelabor rupture of membranes is similar to cerclage management after preterm prelabor rupture of membranes at later gestational ages; it is reasonable to either remove the cerclage or leave it in situ after discussing the risks and benefits and incorporating shared decision-making (GRADE 2C); (7) in subsequent pregnancies after a history of previable or periviable preterm prelabor rupture of membranes, we recommend following guidelines for management of pregnant persons with a prior spontaneous preterm birth (GRADE 1C).

RESUMO

BACKGROUND: Pre-treatment characteristics of women with early breast cancer that are associated with persistent fatigue or suboptimal health-related quality of life (HRQOL) post-chemotherapy need to be identified as potential targets for pre-habilitation. PATIENTS AND METHODS: Ancillary analysis of previously collected data from patients with newly diagnosed Stage I-III breast cancer scheduled to receive chemotherapy. The objective was to identify baseline (pre-chemotherapy) variables associated with meaningful deteriorations in fatigue and other measures of HRQOL from pre-treatment to 6 months after chemotherapy completion. Percentages are reported along with unadjusted and adjusted relative risks. RESULTS: In a sample of 249 women post-chemotherapy, 32% reported worsening fatigue (FACIT-F), 35% worsening Physical Well-Being (PWB), 16% worsening Functional Well-Being (FWB), 8% worsening Emotional Well-Being (EWB), and 30% worsening Social Well-Being (SWB). In multivariable (MV) analysis, variables that were significant in univariate analysis - Black race, high BMI, and baseline poorer EWB - remained significant for worsening post-chemotherapy fatigue (FACIT-F). In MV analysis that included race, education, falls, and baseline EWB, Black race and a positive falls history remained significant for worsening PWB. In MV analysis inclusive of race, Short Physical Performance Battery (SPPB) and FWB, lower SPPB and FWB remained significant predictors of worsening FWB. In MV analysis that included baseline Mental Health Index-Anxiety, EWB and SWB, a higher SWB and lower EWB remained significant for worsening SWB. CONCLUSION: Pre-chemotherapy characteristics in women with early-stage breast cancer that are associated with increased fatigue and reduced HRQOL post-treatment could be used to identify patients who may benefit from pre-habilitation interventions.

RESUMO

It has been widely reported that isoprene emissions from the Arctic ecosystem have a strong temperature response. Here we identify sedges (Carex spp. and Eriophorum spp.) as key contributors to this high sensitivity using plant chamber experiments. We observe that sedges exhibit a markedly stronger temperature response compared to that of other isoprene emitters and predictions by the widely accepted isoprene emission model, the Model of Emissions of Gases and Aerosols from Nature (MEGAN). MEGAN is able to reproduce eddy-covariance flux observations at three high-latitude sites by integrating our findings. Furthermore, the omission of the strong temperature responses of Arctic isoprene emitters causes a 20% underestimation of isoprene emissions for the high-latitude regions of the Northern Hemisphere during 2000-2009 in the Community Land Model with the MEGAN scheme. We also find that the existing model had underestimated the long-term trend of isoprene emissions from 1960 to 2009 by 55% for the high-latitude regions.

RESUMO

Subcutaneous injection of unfractionated heparin (UH) or low molecular weight heparin (LMWH) is frequently utilized for venous thromboembolism chemoprophylaxis. We previously discovered that nurses believe patients experience more pain with UH compared to the LMWH enoxaparin; however, no published studies that are appropriately powered exist comparing pain associated with subcutaneous chemoprophylaxis. Our objective was to assess if differences exist in pain associated with subcutaneous administration of UH and enoxaparin. We conducted an observational study of patients who underwent major abdominal surgery between 11/2017-4/2019. All patients received one of three prophylactic regimens: (1) UH only, (2) Initial dose of UH followed by enoxaparin, or (3) enoxaparin only. Of the 74 patients observed, 40 patients received UH followed by enoxaparin, 17 received UH only, and 17 received enoxaparin only. There was a significant difference in patients' mean perceived pain between subcutaneous UH and enoxaparin injections (mean post-injection pain after UH 3.3 vs. enoxaparin 1.5; p < 0.001). There was no significant difference in perceived pain for patients who received consecutive UH or enoxaparin injections. Differences in pain associated with different chemoprophylaxis agents may be an unrecognized driver of patient refusals of VTE chemoprophylaxis and may lead to worse VTE outcomes.

RESUMO

BACKGROUND: A relatively understudied but growing body of research indicates that individuals with a history of childhood trauma exhibit altered reward processing in adulthood. Research to date has focused on adversity broadly, with studies typically finding evidence of blunted response to rewards in adults with a history of childhood trauma. OBJECTIVE: Given the role of reward processing in risk for psychopathology and the particularly pathogenic nature of sexual abuse (SA), the present study sought to assess whether adults with a history of severe childhood SA exhibit altered neurophysiological response to rewards. PARTICIPANTS AND SETTING: Female adults (N = 105) were included from two study sites that used the same measures of childhood trauma (Childhood Trauma Questionnaire, CTQ), reward processing (Doors Task), and psychopathology (SCID). METHODS: Based on participants' CTQ and SCID responses, three groups were created: Severe SA (n = 36), Clinical Match (with comparable lifetime psychopathology but no-to-minimal SA history; n = 35), and Healthy Controls (n = 34). Group differences in RewP amplitude were assessed. RESULTS: The Severe SA group exhibited larger reward positivity (RewP) amplitude to monetary rewards than the Clinical Match and Healthy Control groups (partial ƞ2 = 0.06, p = .047). This effect remained after covarying for severity of other forms of childhood trauma. CONCLUSIONS: Our study found that severe SA in childhood was related to a heightened response to reward in adulthood. Furthermore, this was not attributable to the severity of other forms of early trauma or comorbid psychopathology. Future studies are needed to identify how heightened reward processing following severe childhood SA may be implicated in the onset and course of psychopathology.

RESUMO

Introduction: Suicidal ideation and behavior (SIB) are serious problems in people with schizophrenia spectrum disorders (SSD). Nevertheless, relatively little is known about the circuitry underlying SIB in SSD. Recently, we showed that elevated emotional impulsivity (urgency) was associated with SIB in SSD. Here we examined brain activity in people with SSD and elevated SIB. Methods: We tested 16 people with SSD who had low SIB and 14 people with high SIB on a task in which emotion regulation in response to affective pictures was implicitly manipulated using spoken sentences. Thus, there were neutral pictures preceded by neutral statements (NeutNeut condition), as well as negative pictures preceded by either negative (NegNeg) or neutral (NeutNeg) statements. After each picture, participants rated how unpleasant each picture was for them. The latter two conditions were compared to the NeutNeut condition. We compared the emotion-regulated condition (NeutNeg) to the unregulated condition (NeutNeut). Statistics were threshold using threshold free cluster enhancement (TFCE). Results: People in the low SIB group showed higher activation in this contrast in medial frontal gyrus, right rostral anterior cingulate, bilateral superior frontal gyrus/DLPFC, and right middle cingulate gyrus, as well as right superior temporal gyrus. Discussion: This study provides clues to the neural basis of SIB in SSD as well as underlying mechanisms.

RESUMO

Multisystem inflammatory syndrome in children (MIS-C) is a rare but severe post-infectious complication of SARSCoV- 2 that seems to occur most frequently two to six weeks after infection. MIS-C can present very similarly to Kawasaki's disease (KD) with symptoms such as a skin rash in addition to a prolonged fever. Here we present a case of a 12-year-old African American/Black female with incomplete KD presenting similarly to MIS-C. The patient presented with prolonged fever, eventually worsening to shock and cardiac dysfunction. We further review the similarities and differences between incomplete KD and MIS-C. Due to their similarities, it is important to keep these diagnoses on the differential when a child presents with a prolonged fever.

RESUMO

Nucleosomes are the fundamental unit of eukaryotic chromatin. Diverse factors interact with nucleosomes to modulate chromatin architecture and facilitate DNA repair, replication, transcription, and other cellular processes. An important platform for chromatin binding is the H2A-H2B acidic patch. Here, we used AlphaFold-Multimer to screen over 7000 human proteins for nucleosomal acidic patch binding and identify 41 potential acidic patch binders. We determined the cryo-EM structure of one hit, SHPRH, with the nucleosome at 2.8 Å. The structure confirms the predicted acidic patch interaction, reveals that the SHPRH ATPase engages a different nucleosomal DNA location than other SF2-type ATPases, and clarifies the roles of SHPRH's domains in nucleosome recognition. Our results illustrate the use of in silico screening as a high throughput method to identify specific interaction types and expands the set of potential acidic patch binding factors. All the screening data is freely available at: https://predictomes.org/view/acidicpatch.

RESUMO

BACKGROUND: Fertility counseling is recommended for adolescent and young adult (AYA) women facing gonadotoxic cancer therapy. However, fertility care is subspecialized medical care offered at a limited number of institutions, making geographic access a potential barrier to guideline-concordant care. We assessed the relationship between geographic access and receipt of fertility counseling among AYA women with cancer. METHODS: Using data from the North Carolina Central Cancer Registry, we identified women diagnosed with lymphoma, gynecologic cancer, or breast cancer at ages 15-39 years during 2004-2015. Eligible women were invited to complete an online survey on various topics, including fertility counseling. Geographic access was measured, using geocoded addresses, as vehicular travel time from residence to the nearest fertility clinic available at diagnosis. Multivariable regression models were used to examine the association between travel time and receipt of fertility counseling by provider type: health care provider vs fertility specialist. RESULTS: Analyses included 380 women. Median travel time to a fertility clinic was 31 (IQR: 17-71) minutes. Overall, 75% received fertility counseling from a health care provider and 16% by a fertility specialist. Women who lived ≥30 minutes from a clinic were 13% less likely to receive fertility counseling by a health care provider (PR:0.87; 95% CI:0.75-1.00) and 49% less likely to receive counseling by a fertility specialist (PR:0.51; 95% CI:0.28-0.93). CONCLUSIONS: Women who lived further away from fertility clinics were less likely to receive fertility counseling. IMPACT: Interventions to improve access to fertility counseling should include strategies to alleviate the burden of geographic access.

RESUMO

Few studies have explored the kinetics of performance and perceived fatigability during high-intensity interval training, despite its popularity. We aimed to characterize the kinetics of fatigability and recovery during an 8 × 4-min HIIT protocol, hypothesizing that most muscle function impairment would occur during the initial four intervals. Fifteen healthy males and females (mean ± standard deviation; age = 26 ± 5 years, V̇O2max = 46.8 ± 6.1 mL·kg-1·min-1) completed eight, 4-min intervals at 105% of critical power with 3 min of rest. Maximal voluntary knee extension contractions (MVCs) coupled with electrical nerve stimulation were performed at baseline and after the first, fourth, and eighth intervals. MVC, potentiated twitch force (Pt), and Db10:100 ratio all declined throughout HIIT (p < 0.05). MVC sharply declined after interval 1 (-15 ± 9% relative to baseline; p < 0.05) and had only further declined after interval 8 (-26 ± 11%; p < 0.05), but not interval 4 (-19 ± 13%; p > 0.05). Pt and Db10:100 also sharply declined after interval 1 (Pt: -18 ± 13%, Db10:100: -14 ± 20%; p < 0.05) and further declined after interval 4 (Pt: -35 ± 19%, Db10:100: -30 ± 20%; p < 0.05) but not interval 8 (Pt: -41 ± 19%; Db10:100: -32 ± 18%; p > 0.05). Voluntary activation did not significantly change across the HIIT protocol (p > 0.05). Evoked force recovery was significantly blunted as more intervals were completed: after interval 1, Pt recovered by 7 ± 11% compared to -6 ± 7% recovery after interval 8 (p < 0.05). Ratings of perceived effort, fatigue, and leg pain rose throughout the session (p < 0.05 for each) and were greater (effort and fatigue) for females (p < 0.05). Otherwise, males and females exhibited similar performance fatigability kinetics, with contractile function declines blunted in response to additional intervals.

RESUMO

Background: Faculty development (FD) is critical to the implementation of competency-based medical education (CBME) and yet evidence to guide the design of FD activities is limited. Our aim with this study was to describe and evaluate an FD activity as part of CBME implementation. Methods: Palliative medicine faculty were introduced to entrustable professional activities (EPAs) and gained experience estimating a learner's level of readiness for entrustment by directly observing a simulated encounter. The variation that was found among assessments was discussed in facilitated debrief sessions. Attitudes and confidence levels were measured 1 week and 6 months following debriefs. Results: Participants were able to use the EPA framework when estimating the learner's readiness level for entrustment. Significant improvements in attitudes and level of confidence for several knowledge, skill, and behavior domains were maintained over time. Conclusions: Simulated direct observation and facilitated debriefs contributed to preparing both faculty and learners for CBME and EPA implementation.

RESUMO

Introduction: When performance data are provided as feedback to healthcare professionals, they may use it to significantly improve care quality. However, the question of how to provide effective feedback remains unanswered, as decades of evidence have produced a consistent pattern of effects-with wide variation. From a coaching perspective, feedback is often based on a learner's objectives and goals. Furthermore, when coaches provide feedback, it is ideally informed by their understanding of the learner's needs and motivation. We anticipate that a "coaching"-informed approach to feedback may improve its effectiveness in two ways. First, by aligning feedback with healthcare professionals' chosen goals and objectives, and second, by enabling large-scale feedback systems to use new types of data to learn what kind of performance information is motivating in general. Our objective is to propose a conceptual model of precision feedback to support these anticipated enhancements to feedback interventions. Methods: We iteratively represented models of feedback's influence from theories of motivation and behavior change, visualization, and human-computer interaction. Through cycles of discussion and reflection, application to clinical examples, and software development, we implemented and refined the models in a software application to generate precision feedback messages from performance data for anesthesia providers. Results: We propose that precision feedback is feedback that is prioritized according to its motivational potential for a specific recipient. We identified three factors that influence motivational potential: (1) the motivating information in a recipient's performance data, (2) the surprisingness of the motivating information, and (3) a recipient's preferences for motivating information and its visual display. Conclusions: We propose a model of precision feedback that is aligned with leading theories of feedback interventions to support learning about the success of feedback interventions. We plan to evaluate this model in a randomized controlled trial of a precision feedback system that enhances feedback emails to anesthesia providers.
