Unleashing excellence: using a project management approach to effectively implement a simulation curriculum to improve residents' preparedness.

BACKGROUND: Integrating innovative, simulation-based training programs into medical curricula frequently encounters familiar challenges, including scepticism, limited faculty time, and financial constraints. Recognized for its success in business projects, the Harvard Project Management Theory emerges as a promising approach to optimizing the implementation process and achieving sustainable success. This study endeavours to elucidate the application of project management theory in our implementation process and assess its impact on the clinical preparedness of novice residents. METHODS: The research utilized a structured four-phase implementation strategy-Planning, Build-up, Execution, and Closing-to develop a simulation-based education curriculum. Incorporating project management tools like project charters and risk management tools played a crucial role in facilitating the effective implementation of standardized processes and improved clinical outcomes. Essential components of this innovative management approach encompass stakeholder engagement, milestone definition, and the alignment of institutional policies and processes. RESULTS: A collective of 395 residents actively engaged in eight monthly simulation-based events, reflecting an average participation rate of 39 residents per lecture (± 19). A noteworthy enhancement was observed in the average rating for knowledge gain, with a significant improvement from 5.9/10 to 8.8/10 (p = 0.0001). Participants highlighted the program's considerable impact on future clinical practice (4.7/5) and teamwork (4.8/5) as particularly valuable aspects. The introduction of a novel organizational structure received favourable feedback from faculty members, with a notable rating of 4.8/5 for predictive time planning. Qualitative insights from the evaluation highlighted the significance of targeted incentive schemes in optimizing the implementation process. CONCLUSION: This project underscores the constructive influence of project management principles in designing simulation-based curricula, explicitly focusing on stakeholder engagement, faculty motivation, and data utilization. Adopting the Harvard Project Management Approach emerges as a catalyst for heightened success in curriculum design, contributing to enhanced emergency preparedness among novice residents. The positive outcomes observed in this study provide valuable insights for future implementations, offering a foundation for refining and optimizing medical education programs to meet the evolving needs of learners and stakeholders alike.

Implementing Artificial Intelligence: Assessing the Cost and Benefits of Algorithmic Decision-Making in Critical Care.

This article provides an overview of the most useful artificial intelligence algorithms developed in critical care, followed by a comprehensive outline of the benefits and limitations. We begin by describing how nurses and physicians might be aided by these new technologies. We then move to the possible changes in clinical guidelines with personalized medicine that will allow tailored therapies and probably will increase the quality of the care provided to patients. Finally, we describe how artificial intelligence models can unleash researchers' minds by proposing new strategies, by increasing the quality of clinical practice, and by questioning current knowledge and understanding.

Pre-clinical Comparison of a High-Definition 3-Dimensional Exoscope and an Operating Microscope: A Prospective Randomized Crossover Study.

OBJECTIVE: The high-definition 3D operating exoscope is a new tool for surgical visualization and magnification that was designed to replace the operating microscope. However, the paucity of studies that have prospectively compared the two systems has made it difficult to draw clear recommendations. The purpose of this study was to compare the operating exoscope and the operating microscope in first-time users in a pre-clinical setting. METHODS: Twenty-eight consecutive medical students were prospectively enrolled and randomized in a crossover design. Each student performed four exercises that required basic microsurgical skills. A tailored questionnaire (Comparison Assessment Tool) was used to subjectively compare the two systems using a 5-point Likert scale. The time needed to perform each task was recorded. A post-intervention cross-sectional survey was conducted to assess the overall quality of the trial session. RESULTS: The operating exoscope was preferred over the operating microscope by most of the students in all items of the Comparison Assessment Tool, particularly with regard to "focusing" and "image quality" (n = 25, 92.6%). A significant difference between groups was found in two exercises that were easier to perform with the operating exoscope. Most of the students considered the overall quality of the evaluation experience to be "very good" (n = 25, 92.6%). CONCLUSIONS: The exoscope allows first-time users to better perform basic microsurgical tasks in a simulated clinical scenario compared to the operating microscope. Further prospective comparative studies will be needed to validate our preliminary findings in an actual clinical scenario.

Hospital Costs and Long-term Survival of Patients Enrolled in an Enhanced Recovery Program for Open Liver Resection: Prospective Randomized Controlled Trial.

BACKGROUND: The clinical benefits of enhanced recovery programs (ERPs) have been extensively researched, but few studies have evaluated their cost-effectiveness. Our ERP for open liver resection is based closely on the guidelines produced by the Enhanced Recovery After Surgery Society (2016). This study follows on from a previous randomized controlled trial. We also undertook a long-term follow-up of the patients enrolled in the original trial alongside an analysis of the associated health economics. OBJECTIVE: We aimed to undertake a health economic and long-term survival analysis as part of a trial investigating the implementation of an ERP for open liver resection. METHODS: The enhanced recovery elements utilized included extra preoperative education, carbohydrate loading, oral nutritional supplements, postresection goal-directed fluid therapy (LiDCOrapid), early mobilization, and physiotherapy (twice a day compared with once per day in the standard care group). A decision-analytic model was used to compare the study endpoints for ERP versus standard care provided to patients undergoing open liver resection. Outcomes obtained included costs per life-years gained. Resource use and costs were estimated from the perspective of the National Health Service of the United Kingdom. A decision tree and Markov model were constructed using results from our earlier trial and augmented by external data from other published clinical trials. Long-term follow-up was also undertaken for up to 5 years after the surgery, and data were analyzed to ascertain if the ERP conferred any benefit on long-term survival. RESULTS: Patients receiving ERP had an average life expectancy of 6.9 years versus 6.1 years in the standard care group. The overall costs were £9538.279 (£1=US $1.60) for ERP and £14,793.05 for standard treatment. This results in a cost-effectiveness ratio of -£6748.33/QALY. Patients receiving ERP required fewer visits to their general practitioner (P=.006) and required lesser help at home with day-to-day activities (P=.04) than patients in the standard care group. Survival was significantly improved at 2 years at 91% (42/46) for patients receiving ERP versus 73% (33/45) for the standard care group (P=.03). There was no statistically significant difference at 5 years after the surgery. CONCLUSIONS: ERPs for patients undergoing open liver resection can improve their medium-term survival and are cost-effective for both hospital and community settings.

Potential harm caused by physicians' a-priori beliefs in the clinical effectiveness of hydroxychloroquine and its impact on clinical and economic outcome - A simulation approach.

BACKGROUND: Despite growing controversies around Hydroxychloroquine's effectiveness, the drug is still widely prescribed by clinicians to treat COVID19 patients. Therapeutic judgment under uncertainty and imperfect information may be influenced by personal preference, whereby individuals, to confirm a-priori beliefs, may propose drugs without knowing the clinical benefit. To estimate this disconnect between available evidence and prescribing behavior, we created a Bayesian model analyzing a-priori optimistic belief of physicians in Hydroxychloroquine's effectiveness. METHODOLOGY: We created a Bayesian model to simulate the impact of different a-priori beliefs related to Hydroxychloroquine's effectiveness on clinical and economic outcome. RESULTS: Our hypothetical results indicate no significant difference in treatment effect (combined survival benefit and harm) up to a presumed drug's effectiveness level of 20%, with younger individuals being negatively affected by the treatment (RR 0.82, 0.55-1.2; (0.95 (1.1) % expected adverse events versus 0.05 (0.98) % expected death prevented). Simulated cost data indicate overall hospital cost (medicine, hospital stay, complication) of 18.361,41€ per hospitalized patient receiving Hydroxychloroquine treatment. CONCLUSION: Off-label use of Hydroxychloroquine needs a rational, objective and datadriven evaluation, as personal preferences may be flawed and cause harm to patients and to society.

High definition three-dimensional exoscope (VITOM 3D) for microsurgery training: a preliminary experience.

PURPOSE: To assess the feasibility of a high definition 3D exoscope (VITOM®) for microsurgery training in a cohort of naïve medical students. METHODS: Twenty-two consecutive medical students performed a battery of four exercises assessing basic microsurgical skills. The students were randomized in two different groups based on two different VITOM® holding systems (VERSACRANE™ and ARTip™ cruise). Participants self-reported the VITOM® system quality on a 4-point Likert scale (VITOM Quality Assessment Tool). The time needed to complete the exercises was analyzed. RESULTS: All students successfully completed the training, and no technical issues were raised during the simulation. The majority of the individual items were judged "good" or "very good" (n = 187; 94.4%), regardless of the two groups. "Image quality" (n = 21; 95%), "magnification rate" (n = 20; 91%), "stereoscopic effect" (n = 19; 86%), and "focusing" (n = 18; 82%) represented the best-rated items. No statistically significant difference between the two groups was measured in almost all items of the VITOM Quality Assessment Tool (p > 0.05). The time needed to perform each exercise showed a statistically significant difference between groups in two tests (p < 0.05). CONCLUSION: This study demonstrated the feasibility of a VITOM-based microsurgery training. The students' subjective assessment of the VITOM® 3D system was promising in terms of technological quality and technical feasibility. Further studies are recommended to define which VITOM® holding system could be more appropriate for microsurgery training.

A cost-effectiveness analysis of postoperative goal-directed therapy for high-risk surgical patients.

OBJECTIVES: Patients undergoing major surgery are at high risk of increased postoperative morbidity and mortality. Goal-directed therapy has been shown to improve outcomes when commenced in the early postoperative period, yet the economic impact remains unclear. The aim of our study was to assess the cost effectiveness of goal-directed therapy as part of postoperative management. DESIGN: Cost-effectiveness analysis to determine short and long term clinical and financial benefits. A decision tree was constructed to determine short-term "in-hospital" costs, based on outcome data derived from a previous study. For a long-term cost-effectiveness analysis, we created a simulation model to estimate life expectancy (quality-adjusted) and lifetime costs for a hypothetical cohort of major noncardiac surgical patients. Cost and outcome comparisons were made between postoperative goal-directed therapy and best standard therapy and described as cost/hospital survivor and cost/patient for the short-term analysis and as incremental cost/quality-adjusted life year for the long-term model. One-way, multiway, and probabilistic analyses were performed to address uncertainties in the model input values, and results were presented graphically in a cost-effectiveness acceptability curve. SETTING: Simulation of a tertiary care department in the United Kingdom. PATIENTS: A hypothetical cohort of high risk surgical patients. INTERVENTIONS: Patients undergoing high-risk surgery were stratified to receive goal-directed therapy or standard best practice to improve tissue oxygenation in the postoperative setting. MEASUREMENTS AND MAIN RESULTS: In our short-term model, goal-directed therapy decreased costs by £2,631.77/patient and by £2,134.86/hospital survivor. The most sensitive variables were relative risk of complication and length of stay. When assuming the worst-case scenario (prolonged ICU and in-hospital stay, highest complication costs, and maximum cost for monitoring), goal-directed therapy still achieved cost savings (£471.70). Our findings also predict that goal-directed therapy not only prolongs quality-adjusted life expectancy (0.83 yr or 9.8 mo) but also leads to incremental cost savings over a lifetime projection of £1,285.77, resulting in a negative incremental cost-effectiveness ratio of - £1,542.16/quality-adjusted life year. CONCLUSION: The implementation of goal-directed therapy is both clinical and cost-effective. Additional implementation expenditures can be offset by savings due to reduced costs accrued from a reduction in complication rates and hospital length of stay. We conclude that goal-directed therapy provides significant benefits with respect to clinical and financial outcomes.

Changes in the mean systemic filling pressure during a fluid challenge in postsurgical intensive care patients.

PURPOSE: The difference between mean systemic filling (Pmsf) and central venous pressure (CVP) is the venous return gradient (dVR). The aim of this study is to assess the significance of the Pmsf analogue (Pmsa) and the dVR during a fluid challenge. METHODS: We performed a prospective observational study in postsurgical patients. Patients were monitored with a central venous catheter, a LiDCO™plus and the Navigator™. A 250-ml intravenous fluid challenge was given over 5 min. A positive response to the fluid challenge was defined as either a stroke volume (SV) or cardiac output increase of greater than 10 %. RESULTS: A total of 101 fluid challenges were observed in 39 patients. In 43 events (42.6 %) the SV and CO increased by more than 10 %. Pmsa increased similarly during a fluid challenge in responders and non-responders (3.1 ± 1.9 vs. 3.1 ± 1.8, p = 0.9), whereas the dVR increased in responders (1.16 ± 0.8 vs. 0.2 ± 1, p < 0.001) as among non-responders CVP increased along with Pmsa (2.9 ± 1.7 vs. 3.1 ± 1.8, p = 0.15). Resistance to venous return did not change immediately after a fluid challenge. Heart performance (Eh) decreased significantly among non-responders (0.41 ± 0.15 vs. 0.34 ± 0.13, p < 0.001) whereas among responders it did not change when compared with baseline value (0.35 ± 0.15 vs. 0.34 ± 0.12, p = 0.15). CONCLUSIONS: The changes in Pmsa and dVR measured at the bedside during a fluid challenge are consistent with the cardiovascular model described by Guyton.

Intensified adjuvant IFADIC chemotherapy in combination with radiotherapy versus radiotherapy alone for soft tissue sarcoma: long-term follow-up of a prospective randomized feasibility trial.

Adjuvant chemotherapy for grade 2 and 3 soft tissue sarcoma (STS) patients still has to be considered experimental. Fifty-nine patients underwent primary surgery by wide or marginal excision and were subsequently randomized to receive radiotherapy alone or in combination with six courses of chemotherapy consisting of ifosfamide, DTIC, and doxorubicin administered in 14-day intervals supported by G-CSF on days 5-13. Twenty-eight patients received radiotherapy (control group) and 31 patients were treated with additional chemotherapy. After a median observation period of 97 months (range: 13-158 months), 58 patients were followed up to assess long-term relapse-free survival (RFS), time to local failure (TLF), time to distant failure (TDF), and overall survival (OS). Fifteen patients (56%) in the control group vs. 19 patients (61%) in the chemotherapy group were free of disease. Within the control group, tumor relapses occurred in 12 patients (44%) vs. 12 patients (39%) in the chemotherapy group. RFS (P = 0.87), TLF (P = 0.58), TDF (P = 0.60) as well as OS (P = 0.99) did not differ significantly between the two groups. Adjuvant chemotherapy was not translated into a significant benefit concerning RFS, TLF, TDF, and OS for STS patients.
