    Comparison of corneal astigmatism and axis location in cataract patients measured by total corneal power, automated keratometry, and simulated keratometry
    (2012-12-01) Sabong Srivannaboon; Soeharnila; Chareenun Chirapapaisan; Pratuangsri Chonpimai; Mahidol University; Faculty of Medicine, Siriraj Hospital, Mahidol University; Klinik Mata Nusantara
    of astigmatism. Results: One hundred eyes of 100 cataract patients were randomly selected. There was no statistically significant difference in the mean steepest axis between TCP (93.31 ± 68.75 [SD]), automated keratometry (94.24 ± 64.78), and simulated...Purpose: To compare the corneal astigmatism (magnitude and axis location) derived by total corneal power (TCP), automated keratometry, and simulated keratometry. Setting: Siriraj Hospital, Mahidol University, Bangkok, Thailand. Design: Prospective

    Improving patient's waiting time at a health screening center
    (2012-01-01) T. Wongsammacheep; J. Pichitlamken; W. Weerawat; Kasetsart University; Mahidol University
    The health screening center is the first department that patients come into contact before going to other departments. Patients sometimes complain about long waiting times at this center. We develop a discrete-event simulation model of the health... with staff. The simulation model is validated by considering the average total times in the system of one health checkup package. In this paper, we use the simulation model to test our patient's adaptive policies to see if patient's waiting time can

    Simulation modeling for facility allocation of outpatient department
    (2018-07-03) Duangpun Kritchanchai; Soriya Hoeur; Mahidol University
    . This process starts by describing patient flow at the OPD; then the new OPD is built, and some support facilities are moved to the new building. Discrete-event simulation technique is used to model the patient flow at the OPD and the new OPD. Simulation...© 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group. In the value chain model, activities of one firm can be classified into two types: primary activities and support activities. From such a concept, patient flow in outpatient

The simulation model quantifies the chronic, high patient congestion that is prevalent amongst Thai public hospitals with very high patient-to-doctor ratios. Our model can be applied across five...The orthopedic outpatient department (OPD) ward in a large Thai public hospital is modeled using Discrete-Event Stochastic (DES) simulation. Key Performance Indicators (KPIs) are used to measure effects across various clinical operations during

    The Evaluation of Meropenem Dosing Regimens Against ESBL-Producing Escherichia coli in ICU Patients Using Monte Carlo Simulation
    (2022-01-01) Win E.E.; Htun K.W.; Tragulpiankit P.; Tangtrakultham S.; Montakantikul P.; Mahidol University
    Purpose: To evaluate the optimal dosing regimens of meropenem against extended-spectrum beta-lactamase-producing Escherichia coli (ESBL E. coli) in critically ill patients with varying degrees of renal function using Monte Carlo simulation (MCS...-pharmacodynamic index. For each dosing regimen, 10,000 virtual patients were generated to assess the probability of target attainment (PTA) and the cumulative fraction of response (CFR). The most effective dosage regimens were determined using PTA and a CFR of 90

    Asian Rhinoplasty: Preoperative Simulation and Planning Using Adobe Photoshop
    (2015-11-01) Kidakorn Kiranantawat; Anh H. Nguyen; Mahidol University; Baylor College of Medicine
    © Georg Thieme Verlag KG Stuttgart, New York. A rhinoplasty in Asians differs from a rhinoplasty performed in patients of other ethnicities. Surgeons should understand the concept of Asian beauty, the nasal anatomy of Asians, and common problems... encountered while operating on the Asian nose. With this understanding, surgeons can set appropriate goals, choose proper operative procedures, and provide an outcome that satisfies patients. In this article the authors define the concept of an Asian

    Colistin dosing regimens against pseudomonas aeruginosa in critically ill patients: An application of monte carlo simulation
    (2021-05-01) Van Thi Khanh Nguyen; Preecha Montakantikul; Pramote Tragulpiankit; Jantana Houngsaitong; Mohd Fazli Shuib; Mahidol University; FV Hospital
    Our aims are to assess various colistin dosing regimens against Pseudomonas aeruginosa (P. aeruginosa) infection in critically ill patients and to propose an appropriate regimen based on microbiological data. A Monte Carlo simulation was performed...-resistant P. aeruginosa rates were 29.8% and 0.8%, respectively. MIC50,90 were both 0.5 mg/L. The simulated results showed that at MIC of 2 mg/L, most regimens could not reach the PTA target, particularly in patients with normal renal function (Creatinine

The efficacy pharmacodynamic (PD) target was calculated for CQ blood concentration based on the literature's successfully treated COVID-19 adult regimen. The safety PD... targets were derived from the literature regarding any adverse effects (AEs) and QTc prolongation.

    Association between cardiopulmonary resuscitation audit results with in-situ simulation and in-hospital cardiac arrest outcomes and key performance indicators
    (2023-12-01) Ruangsomboon O.; Surabenjawongse U.; Jantataeme P.; Chawaruechai T.; Wangtawesap K.; Chakorn T.; Mahidol University
    Introduction: In-situ simulation (ISS) is a method to evaluate the performance of hospital units in performing cardiopulmonary resuscitation (CPR). It is conducted by placing a high-fidelity mannequin at hospital units with simulated scenarios... and having each unit’s performance evaluated. However, little is known about its impact on actual patient outcomes. Therefore, we aimed to evaluate the association between the ISS results and actual outcomes of patients with in-hospital cardiac arrest (IHCA
