Résumé :

One of the keys to success in construction execution is timeliness. In fact, construction is often late than originally planned. It’s caused by project scheduling uncertainty. Deterministic scheduling methods use data from previous projects to determine work duration. However, not every project has same work duration. The PERT method provides a probabilistic approach that can overcome these uncertainties, but it doesn’t account for the increase in duration due to parallel activities. In 2017, the PERT method was developed into the M-PERT method. The purpose of this study is to compare the mean duration and standard deviation of the overall project between PERT and M-PERT methods and compare them in Monte Carlo simulation. The research method used is to calculate the mean duration of the project with the PERT, M-PERT, and Monte Carlo simulation. The study was applied to a three-story building project. From the results of the study, the standard deviation obtained was 5.079 for the M-PERT method, 8.915 for the PERT method, and 5.25 for the Monte Carlo simulation. These results show the M-PERT method can provide closer results to computer simulation result than the PERT method. Small standard deviation value indicates the M-PERT method gives more accurate results.ABSTRAKSalah satu kunci keberhasilan dalam suatu pelaksanaan konstruksi adalah ketepatan waktu. Kenyataannya, pelaksanaan konstruksi sering mengalami keterlambatan waktu dari yang direncanakan. Hal ini disebabkan oleh ketidakpastian dalam merencanakan penjadwalan proyek. Metode penjadwalan yang bersifat deterministik menggunakan data dari proyek sebelumnya untuk menentukan durasi pekerjaan. Akan tetapi, tidak setiap proyek memiliki durasi pekerjaan yang sama. Metode PERT memberikan pendekatan probabilistik yang dapat mengatasi ketidakpastian tersebut, tetapi metode ini tidak memperhitungkan pertambahan durasi akibat adanya kegiatan yang berbentuk paralel. Pada tahun 2017, metode PERT dikembangkan menjadi metode M-PERT. Tujuan dari penelitian ini adalah membandingkan mean durasi dan standar deviasi proyek secara keseluruhan antara metode PERT dan M-PERT dan membandingkan kedua metode tersebut dalam simulasi Monte Carlo. Metode penelitian yang dilakukan adalah menghitung mean durasi proyek dengan metode PERT, M-PERT, dan simulasi Monte Carlo. Penelitian diterapkan pada proyek gedung bertingkat tiga. Dari hasil penelitian, nilai standar deviasi diperoleh sebesar 5,079 untuk metode M-PERT, 8,915 untuk metode PERT, dan 5,25 untuk simulasi Monte Carlo. Hasil ini menunjukan metode M-PERT dapat memberikan hasil yang lebih mendekati hasil simulasi komputer daripada metode PERT. Nilai standar deviasi yang kecil menunjukan metode M-PERT memberikan hasil yang lebih akurat.

Résumé :

696 Background: PERT is an important but costly and inconsistently used supportive care medication in PC. We sought to characterize patterns of PERT use among U.S. insured patients with PC. Methods: We conducted a retrospective observational analysis of patients with a primary diagnosis of pancreatic adenocarcinoma in the IBM MarketScan national claims database between 2013-2019. We identified pharmacy claims for PERT (Creon, Pancreaze, Pertzye, Viokace, and Zenpep) and classified patients as PERT-users (≥ 1 PERT prescription [Rx]) and non-PERT users. We used descriptive statistics for clinical, demographics, and costs. Multiple logistic regression identified predictors of PERT use. Kaplan-Meier method assessed time from PC diagnosis to first PERT Rx. Results: Of 19,866 patients with PC (median age 62 years, 49% women), 6,918 (35%) were PERT-users. The median follow-up was 11 months (PERT users: 14 months, non-PERT users: 9 months). Overall, 43% of patients received no cancer-directed treatment. PERT-users were more likely to have a history of pancreatitis (acute, odds ratio [OR] = 1.9; chronic, OR = 3.6), and received chemotherapy (OR = 1.2), surgery (OR = 2.3), and radiation (OR = 1.4). Among all PERT-users, the median time from PC diagnosis to first fill was 1.9 months (95% CI: 1.8,2.0). The median time from surgery to first fill was 1.6 months (95% CI: 1.4,1.7). The median number of PERT Rxs was 4; 22% of PERT-users received 1 Rx. A median of 150 days of PERT was supplied across all Rxs per patient. The median (IQR) cost of each PERT Rx was $25 ($0- $50). PERT accounted for 16% of all drug out-of-pocket costs (OOPC) (excluding systemic outpatient cancer-directed treatment), and 7% of all healthcare OOPC. Patients with PERT had significantly higher monthly OOPC on Rxs but lower on all other services, including inpatient and outpatient services (all p < 0.0001). Overall, PERT-users had significantly lower per-patient per-month (PPPM) OOPC vs non-PERT users ($469, vs $520, p < 0.0001). They also had fewer PPPM outpatient (0.7 vs 1.2, p < 0.0001) and ER (0.4 vs 0.5, p < 0.0001) visits. Conclusions: In this national study of insured U.S. adults with PC, only one-third received PERT. Of those receiving PERT, approximately a fifth received just a single Rx. PERT users, despite higher OOP drug spending had reduced overall OOP costs and fewer healthcare visits. These data highlight the need to explore non cost-related reasons for lack of and ways to standardize PERT use.

Résumé :

400 Background: Current NCCN guidelines recommend PERT use in PC patients (pts) with symptoms of EPI. However, little evidence exists regarding clinical outcomes following PERT use in PC pts, especially those with nonresected disease. We present initial results from PERT use in this pt group regarding disease control and symptom improvement. Methods: Pts with initially nonresected PC were obtained for this study from the Virginia Mason PC Database. Eligibility criteria included:1) pathologically diagnosed nonresected adeno PC from January 2014-December 2019 ; 2) no prior PC anticancer therapy (PCRx) of any kind; 3) ≥2 PGSGA (Patient Generated Global Subjective Assessment ) forms completed with initial PGSGA reporting before 30 days following first PCRx. Pts were stratified by PERT vs non-PERT prescription as validated by the EHR. Clinicians tended to prescribe PERT based on either abnormal fecal elastase and/or clinical symptoms (e.g. diarrhea) as in the PGSGA; no formal criteria for PERT usage existed. Pts were considered to have received PERT if prescribed for the majority of time during the assessment period (i.e. > 30 days) and were analyzed based on an "intent to treat" basis without compliance validation. Results: 344 pts were identified via this method ; 207 (60%)/137 (40%) did/did not receive PERT. > 95% received Creon as PERT. Median time from 1st day PCRx to 1st reassessment was 60 days. 79% pts completed PGSGA prior to and 97% within 2 weeks of 1st day PCRx. Pt characteristics were balanced between PERT/ non PERT groups including race (90% white), age (median 68 yrs), sex (M/F 53%/47%), non-metastatic/metastatic disease 24%/76% . BMI distribution (< 18.5 3%, 18.5-25 40%, 25-30 34%, and >30 23%),and albumin distribution (<3 g/dL 6%, 3-3.4 g/dL 12% and ≥3.5 g/dL 82%). However, mean baseline PGSGA score was higher in the PERT vs non PERT group (9.9 overall, 10.9 (95% CI 10.1-11.7) vs 8.2 (95% CI 7.3 - 9.1), p< 0.01). At 1st reassessment, disease control (PR+SD) (83% overall) was greater in the PERT (87%) vs. non PERT (79%) group (p=0.04).Change from baseline PGSGA was favorable overall (Δ-5.0, 95% CI-5.7--4.3), and in all pt subsets, but with greater improvement in the PERT (Δ-6.0) vs. non PERT (Δ -3.4) group (p< 0.001) and in disease controlled (Δ-5.3) vs. non-disease controlled (Δ- 3.2) pts (p=0.033). Disease controlled vs. non-disease controlled PERT pts did not differ in their PGSGA response (Δ-6.2/-4.8, p=0.98) Conclusions: 1) PERT vs non-PERT pts were similar with respect to basic clinical or nutritional parameters (e.g. BMI, albumin) in this pt cohort. 2) Despite having more adverse baseline PGSGA scores, PERT pts were statistically superior to non PERT pts with respect to both frequency of disease control and magnitude of PGSGA response during initial Rx 3) Further investigation of the detail involving PERT usage and clinical outcomes in nonresected PC is warranted from these data.

Résumé :

e16254 Background: Weight loss (WL)/cachexia is common in APDAC and associated with multiple adverse pt outcomes. Current NCCN guidelines recommend PERT in PDAC patients with PEI. However, little evidence exists regarding PERT use and clinical outcomes in PDAC, especially APDAC. We present here data on impact of PERT use from our institution. Methods: Study pts were identified from the Virginia Mason PDAC database (01-2010-12/2019). Eligibility criteria included: 1) No upfront resection, 2) no prior PDAC therapy, 3) FE 1 < 200 µg/g or documented evidence of PEI at diagnosis, 4) treatment at least to initial restaging event (8 wks), and 5) data regarding PERT use/dosage available. Pts were stratified by PERT/non-PERT usage. PERT use was defined by prescription for >50% of time from initial Rx to 1st restage using recommended dosing per package insert. Pts on PERT for < 50% of time during this time frame and/or prescribed less than recommended dose were excluded from analysis. Results: 505 total pts were study eligible, PERT 197(39%), non-PERT 308(61%). WL (80 vs 65%, p< 0.001) and cachexia (74 v 54%, p<0.001) were more common in PERT pts. ECOG PS 2 (4 vs 9%, p=0.02) and non-metastatic disease (51 vs 40%, p=0.02) more common in non-PERT pts. Other pt characteristics (age, sex, diabetes at dx, serum albumin, NLR, BMI distribution, % obese) were similar in both groups. OS after adjustment for PS and stage was 15.7 mo (95% CI 13.6-18.3 mo) among PERT users vs. !2.6 mo non-PERT users (95% CI 11.0 -13.7 mo, p=0.02, adjusted hazard ratio 0.81 (95% CI 0.67-0.99). Pts receiving PERT also tended to have a higher therapeutic response rate by both Ca 19.9 and CT: but without statistical significance (p=0.10, 0.09, respectively). Regarding nutrition, PERT vs. non-PERT pts at 8 weeks experienced less WL (-0.4 vs. -1.5 kg, p=0.03) and less change in BMI (-0.3 vs -1.6, p=0.02). This was true even in cachectic pts at dx (change in BMI + 0.1 vs -1.7, p=0.01). Additional analyses of impact of PERT on QOL are ongoing, including in a subset of patients who underwent serial PG-SGA scoring. Conclusions: In this pt cohort, APDAC pts prescribed PERT per recommended dosing had a statistically significant improvement in median OS vs. those not prescribed PERT. This remained true in multivariate analysis after adjustment for population imbalances. PERT use was also associated with a statistically significant reduction in weight loss and change in BMI at 8 weeks, even in those patients defined as cachectic at diagnosis. Further investigation into a) impact of PERT on quality of life, b) mechanisms producing the above observations, c) confirmatory observations in independent datasets, and d) additional therapeutic interventions designed to mitigate weight loss/cachexia in PDAC are needed.

Résumé :

We investigated the relationship between self-reported adherence to pancreatic enzyme replacement therapy (PERT), nutritional status, and all-cause hospitalization in cystic fibrosis (CF) patients with a record of PERT use. Association of self-reported annual PERT use rate (adherence) with annual hospital admission rate (HAR) and annual total hospital nights (THNs) were analyzed for 5301 children (2000–2012) and 13,989 adults (2000–2013) from the CF Foundation Patient Registry. Multivariate linear regression was used to determine the association of HAR and THN with mean annual PERT use rate, cumulative PERT use rate, mean body mass index (BMI) (adult) or BMI percentile (pediatric), age, and sex. The median annual PERT use rate was 87% in children and 80% in adults. Statistically, higher annual PERT use, longer cumulative PERT, and higher BMI percentile (children) or BMI (adults) were significantly ( p < 0.0001) associated with lower annual HAR and fewer annual THN in children and adults. Female sex was associated with higher annual HAR and more annual THN in children and adults ( p < 0.05). Results indicate self-reported adherence to PERT, increased BMI, and male sex were associated with fewer hospital admissions and annual hospital nights in CF patients.

ABSTRACT Approximately 80-90% patients with cystic fibrosis will experience pancreatic insufficiency. This condition will cause the malabsorption of fats and proteins and will affect the nutritional status of the patients. Therapy of pancreatic insufficiency is by administering of pancreatic enzyme replacement therapy (PERT) to increase absorption of fat and protein in patients with cystic fibrosis. This systematic review aimed determine the efficacy and safety of the administration of PERT in patients who experience pancreatic insufficiency with cystic fibrosis, and this systematic review can be used as reference or guideline in the administration of PERT. The search strategy was undertaken using PUBMED and Cochrane Library, and the search term were “PERT” and “Cystic Fibrosis” wich were combines with the use of Boolean operator “AND”. In total, 14 studies were include in the final review with criteria is RCT, patients of any age, patients with cystic fibrosis and pancreatic insufficiency, and compared to placebo or other formulations. All studies showed an increase in the % CFA from administration of PERT. the increase of % CFA from all studies reached a range of > 60% to > 80%. Studies comparing PERT and placebo showed that PERT was able to increase of % CFA to > 70% while placebo had % CFA about 40% and PERT therapy was considered relatively safe and well tolerated by patients with cystic fibrosis.

Résumé :

Nutritional supplements for patients with exocrine pancreatic insufficiency (EPI) typically utilize pancreatic enzyme replacement therapy (PERT) which is associated with gastrointestinal side effects. We evaluated serum triglyceride levels in patients with cystic fibrosis following consumption of an enzyme-modified oil oral nutritional supplement (EMO-ONS) versus a standard triacylglycerol-based ONS product (TAG-ONS) used concomitantly with PERT and patient tolerability between the two approaches. Ten subjects with CF and EPI taking PERT were enrolled in a single-center, double-blind, cross-over proof of concept trial. Five subjects randomized to Arm 1 were administered a PERT placebo and EMO-ONS and 5 subjects in Arm 2 were administered TAG-ONS+PERT. After 4 to 14 days, subjects received the opposite ONS. Serum triglyceride levels were measured at baseline and hourly for 6 h. Following the above, subjects were randomly assigned to receive 2 daily servings of EMO-ONS+PERT placebo or TAG-ONS+PERT at home for 7-days, self-reporting gastrointestinal symptoms daily. Mean change in peak serum triglyceride levels were similar for both groups (EMO-ONS = 41.9 ± 46.7 mg/dL vs. TAG-ONS+PERT = 46.4 ± 44.1 mg/L; p = 0.85). There was no difference in mean ratio of the serum triglyceride AUC between the two groups (p = 0.58) or self-reported gastrointestinal tolerance. EMO-based products may provide a PERT-free alternative to traditional ONS products in patients with cystic fibrosis.

Résumé :

The PERT (Program Evaluation Review Technique) is a operational research tool used to schedule and coordinate activities in a complex project. We present two values for measuring the importance of each activity. Both values are obtained through an axiomatic characterization using three properties. The first value is characterized with separability, monotonicity, and order preservation. The second value is characterized with separability, equal treatment inside a component, and independence of large durations. We also present an application to the problem of how to share the surplus obtained when a project finishes before the expected completion time.

Résumé :

401 Background: Pancreatic enzyme replacement therapy (PERT) can reduce symptoms of indigestion and improve nutrition in patients with exocrine pancreatic insufficiency. PERT is under-prescribed, and this may be related to actual costs and prescriber sensitivity to these costs. Thus, we aimed to assess PERT costs. Methods: We used Medicare Part D formulary and pricing files for the first quarter of 2020 to conduct a patient-level modeling study to describe point-of-sale and out-of-pocket costs for each PERT formulation among Part D stand-alone and Medicare Advantage prescription drug plans. We calculated costs across nationwide plans under three scenarios: (1) standard benefit design ($435 deductible and 25% coinsurance after the deductible is met); (2) 25% coinsurance (for fills after the deductible and in the coverage gap until the patient spends $6,350 out-of-pocket); and (3) 5% coinsurance (once catastrophic coverage is reached). PERT doses are identified by the lipase content per capsule (in United States Pharmacopeia, USP, units). We calculated the number of units for each PERT formulation/ dose form that would provide optimally dosed PERT for the average US adult (250,000 USP units of lipase per day), based on guidelines and consensus. We first calculated costs for a single unit of PERT. Next, we calculated the number of units needed daily for each formulation/ dose form to provide optimally dosed PERT, and multiplied it by 30 to generate 30-day requirements and costs. Results: Across 3,974 plans nationwide, five PERT formulations in seventeen different doses were covered by Medicare plans in 2020. The range of lipase content in a single unit ranged from 3,000 to 40,000 USP units, and the per-unit list price ranged from $1.44 to $13.89. The point-of-sale price for a 30-day supply of optimally dosed PERT ranged from $2,109 to $4,840. For patients, the expected out-of-pocket costs for a 30-day supply of optimally dosed PERT averaged $999 across formulations (range, $853 to $1536) for those paying a deductible and coinsurance, $673 (range, $527 to $1210) for fills made after meeting the deductible until reaching catastrophic coverage, and $135 (range, $105 to $242) after reaching catastrophic coverage. Conclusions: In this analysis of 2020 Medicare Part D plans, the estimated out-of-pocket cost for just a 30-day supply of optimally dosed PERT was high— at least $100 in the catastrophic phase and approximately $1,000 in the initial phase. In the setting of pancreas cancer, already associated with heavy symptom burden and distress, the financial burden from a supportive care intervention (such as PERT) has been underappreciated. These costs may serve as a barrier to Medicare beneficiary drug access and contribute to financial toxicity.

Résumé :

698 Background: Malnutrition/cachexia is common in PC and is associated with multiple adverse patient (pt) outcomes. Current NCCN guidelines recommend PERT in PC pts with exocrine pancreatic insufficiency (EPI). However, little evidence exists regarding the impact of PERT on clinical outcomes in PC, especially APC. Data on impact of PERT use on change in body weight is presented here. Methods: Pts in this retrospective cohort study were identified from the Virginia Mason PC database. Eligibility requirements included: 1) no upfront resection 2) no prior PC therapy 3) pancreatic stool elastase 1< 200 µg/g stool or documented clinical evidence of EPI at diagnosis 4) treatment at least to initial restaging event (8 weeks) 5) available data regarding PERT use/dosage. Weight/BMI was assessed at baseline and after 8 weeks on therapy. Two pt groups were compared; a) pts prescribed PERT for EPI at recommended package insert dose (≥ 500KU-2500/kg/meal for ≥ 3 meals/day) for ≥ 50% treatment period and b) pts who received no PERT. Pts on PERT at lower than recommended dose and /or < 50% interval between 1st treatment and reassessment were excluded from analysis. Statistical significance was determined using the T-test for continuous variables, chi-squared for categorical variables. Results: 505 total pts were study eligible; 197 (39%) pts received PERT, 308 (61%) pts did not. Pt characteristics are shown. Despite a more adverse patient population with respect to weight loss, pts receiving PERT after 8 weeks experienced less change in weight (-0.36 kg vs -1.54 kg, P = 0.025) and change in BMI ( -0.64% vs -1.96., p= 0.026). Pts with cachexia experienced a similar outcome (-0.36% vs. -2.02 %, p= 0.026). No other pt characteristics achieved statistical significance. Conclusions: Despite a more adverse population with respect to weight loss at baseline, PERT usage prescribed per package insert guidance reduced wt loss/ change in BMI loss in APC over the 1st 8 weeks of therapy. This was also true in APC pts with cachexia. Further analysis of the impact of PERT therapy in APC with respect to treatment tolerability, and toxicity, quality of life and overall survival is warranted. [Table: see text]

Résumé :

Abstract The idea to build the Sunda Strait Bridge, popularly known as Jembatan Selat Sunda (JSS), began in the government of Indonesia's first president, Sukarno, which connect two islands with the largest economy in Indonesia, Sumatra Island and Java Island. This ambitious project will become a single mega infrastructure project with the largest investment in Indonesia. The successful completion of a project can be associated to the completion of a project on time. Accurate calculation of project time duration estimation is the key to the success of an infrastructure project delivery on time. Many practitioners in construction industry nowadays are having difficulties to estimates project duration correctly. Choosing the appropriate method in scheduling planning is the key to the successful estimation of a project. This research proposes the use of the M-PERT scheduling method which is the development of the conventional PERT with a higher degree of accuracy. As a case study, this research uses the Suspension Bridge section, which is one part of the overall phase of the construction of the JSS infrastructure project. The results of this research produce estimates of the project duration using M-PERT is 2104.38 days. It gives the estimation error is less than 1% when compared with the simulated curves. As a comparison, this research also calculates duration estimation using conventional PERT and it gives 2013 days with error more than 24% when compared with the simulated curves. A step-by-step process to estimate project duration using M-PERT method are also include in supplemental data. Keywords: Jembatan Selat Sunda, M-PERT, PERT, scheduling, simulated curves Abstrak Gagasan untuk membangun Jembatan Selat Sunda (JSS) dimulai pada masa pemerintahan presiden pertama Indonesia, Sukarno, yang menghubungkan dua pulau dengan ekonomi terbesar di Indonesia, Pulau Sumatera dan Pulau Jawa.

Résumé :

The PERT network diagram optimization and the node layout optimization were studied in order to solve the difficulty of using manual methods to generate the PERT network chart in large-scale software project management. The new methods of optimization the node of PERT was proposed based on ant colony optimization algorithm (ACO) and genetic algorithms (GAs). The high adaptability and population optimization technology of GAs are discussed and also the ACO is introduced to realize the nodes layout global adjustment. In the end, calculation and simulation results show that the methods proposed can make the number of nodes of PERT network diagram generated automatically minimum. Meanwhile, it can make the layout of nodes of PERT network diagram more efficient and effective, so as to effectively solve the large-scale software project assessment problem.

Résumé :

Indonesia is one of the few countries in the world with very high burden of tuberculosis (TB). Tubercular pleural effusion (Pleural TB) is the most common form of extra-pulmonary TB, however the remains a common clinical challenge. This research from May 2017 through September 2017 a total of 42 patients with exudative lymphocytic pleural effusions suspected to pleural tuberculosis were enrolled in this study. Adenosine deaminase (ADA) and Gene X-pert were examined from pleural fluid. Diagnosis was made clinically or based from sputum/pleural fluid culture. The result of this research showed out of all participants, 64,3% (27/42) had ADA in positive level (>40 IU/L) and 31% (13/24) had Gene X-pert positive Mycobacterium Tb. The Gene X-pert sensitivity was 40.7% with specificity 86.6%, PPV and NPV were 44.8% and 57.1% respectively. Kappa Compatibility study show that Gene X-pert point was 0.227 (p 0.066). The usefulness of Gene X-pert to diagnose pleural TB is limited by its poor sensitivity. Gene X-pert cannot be used as single diagnostic tool for tuberculous pleural effusion

Résumé :

Background: Pulmonary embolism (PE) is a common illness with significant mortality without appropriate treatment. Its disease severity is variable, difficult to prognosticate and triage of severe PE remains a patient safety concern. Some PE may benefit from invasive and advanced medical therapy, but these decisions require complex multi-disciplinary coordinated care. We have launched a multi-disciplinary rapid response team at the Foothills Medical Center Hospital (FMC) to assist prognostication, treatment, disposition planning, and followup for high-risk PE: The Pulmonary Embolism Response Team (PERT). Aim Statement: PERT has been implemented to improve patient-oriented outcomes however, as severe PE is infrequent, we initially target process measures. In the first year of PERT rollout, we aim for: 1) 100% of high risk PE be detected by emergency for PERT consult 2) PERT response be within 45 minutes of activation 3) PERT treatment and disposition be made within 1 hour of consult. 4) > 80% of patient dispositions match those informed by evidence-based risk stratification tools. Measures & Design: Through collaboration between emergency medicine, radiology, cardiac sciences, medical specialties and critical care, a collective evidence-based PE risk stratification/treatment pathway was developed. This has been disseminated to providers and embedding into electronic medical records (EMR) for computer assisted decision-making support. EMR data has been harmonized with standardized radiographic reporting for PE to cue reporting of high risk imaging findings. Standardized imaging and EMR prognostic factors flag high risk PE suggesting PERT activation. PERT standard operating procedures have been developed, including evidenced-based pathways for further therapy, advanced imaging, and subspecialized disposition planning. Clinical services meet quarterly, and review dashboard summary data on clinical adverse events, resource utilization, and time data of patient flow to revise PE care pathways. Evaluation/Results: PERT activations occur approximately 2 times weekly. Adherence to operating procedures is high. Feedback post implementation cites improved adherence to evidence-based practice, clearer communication, and faster patient disposition. Quantitative analysis of performance is limited by infrequency of cases. Discussion/Impact: Our project shows feasibility of a PERT service. Pre-implementation data is collected, and we are currently measuring these post. We suspect signal of improved patient-oriented outcomes will be detected with more cases.

Résumé :

This research identified the roadblocks or shortcomings of PERT/CPM in the context of a construction company and suggested a plan to address the identified gaps. The researchers used a descriptive research design to discover the shortcomings of the PERT/CPM in construction management planning, especially in the Cabanatuan City, Nueva Ecija, Philippines construction industry. As a result, PERT/CPM is a project management approach that is useful in the basic administrative functions of planning, scheduling, and control. These days, business houses undertake massive projects that take years to complete before commercial development can begin. While this tool can be very useful, the majority of respondents agreed that it has limitations, such as; PERT/CPM can become ineffective and difficult to manage if it is not well-defined and stable for active control of a project; PERT/CPM requires frequent updating and revising of calculations, which is an extensive and time-consuming exercise that requires highly specialized knowledge; PERT/CPM requires frequent updating and revising of calculations, which is an expansive and time-consuming exercise that requires highly specialized knowledge; Furthermore, it is unable to efficiently accommodate abrupt shifts in the ground plan's execution. However, despite its limitations, PERT/CPM is still recommended for construction management planning, especially in large projects. The project manager must always have a contingency plan in place so that the quality of his or her work and projects won’t be jeopardized. In order to make the best use of all available resources in their production, a cost-benefit analysis must be performed, as well as additional research about PERT/CPM. The study's findings have implications for mathematics education in architecture.

Résumé :

BackgroundThe impact of pulmonary embolism response teams (PERTs) on treatment choice and outcomes of patients with acute pulmonary embolism (PE) is still uncertain.ObjectiveTo determine the effect of PERTs in the management and outcomes of patients with PE.MethodsPubMed, Embase, Web of Science, CINAHL, WorldWideScience and MedRxiv were searched for original articles reporting PERT patient outcomes from 2009. Data were analysed using a random effects model.Results16 studies comprising 3827 PERT patients and 3967 controls met inclusion criteria. The PERT group had more patients with intermediate and high-risk PE (66.2%) compared to the control group (48.5%). Meta-analysis demonstrated an increased risk of catheter-directed interventions, systemic thrombolysis and surgical embolectomy (odds ratio (OR) 2.10, 95% confidence interval (CI) 1.74–2.53; p<0.01), similar bleeding complications (OR 1.10, 95% CI 0.88–1.37) and decreased utilisation of inferior vena cava (IVC) filters (OR 0.71, 95% CI 0.58–0.88; p<0.01) in the PERT group. Furthermore, there was a nonsignificant trend towards decreased mortality (OR 0.87, 95% CI 0.71–1.07; p=0.19) with PERTs.ConclusionsThe PERT group showed an increased use of advanced therapies and a decreased utilisation of IVC filters. This was not associated with increased bleeding. Despite comprising more severe PE patients, there was a trend towards lower mortality in the PERT group.

Résumé :

Coronavirus disease 2019 (COVID-19) may predispose patients to venous thromboembolism (VTE). Limited data are available on the utilization of the Pulmonary Embolism Response Team (PERT) in the setting of the COVID-19 global pandemic. We performed a single-center study to evaluate treatment, mortality, and bleeding outcomes in patients who received PERT consultations in March and April 2020, compared to historical controls from the same period in 2019. Clinical data were abstracted from the electronic medical record. The primary study endpoints were inpatient mortality and GUSTO moderate-to-severe bleeding. The frequency of PERT utilization was nearly threefold higher during March and April 2020 ( n = 74) compared to the same period in 2019 ( n = 26). During the COVID-19 pandemic, there was significantly less PERT-guided invasive treatment (5.5% vs 23.1%, p = 0.02) with a numerical but not statistically significant trend toward an increase in the use of systemic fibrinolytic therapy (13.5% vs 3.9%, p = 0.3). There were nonsignificant trends toward higher in-hospital mortality or moderate-to-severe bleeding in patients receiving PERT consultations during the COVID-19 period compared to historical controls (mortality 14.9% vs 3.9%, p = 0.18 and moderate-to-severe bleeding 35.1% vs 19.2%, p = 0.13). In conclusion, PERT utilization was nearly threefold higher during the COVID-19 pandemic than during the historical control period. Among patients evaluated by PERT, in-hospital mortality or moderate-to-severe bleeding were not significantly different, despite being numerically higher, while invasive therapy was utilized less frequently during the COVID-19 pandemic.

Résumé :

Penjadwalan proyek membantu menunjukkan hubungan setiap aktivitas dengan aktivitas lainnya dan terhadap keseluruhan proyek, mengidentifikasi hubungan yang harus didahulukan diantara aktivitas, serta menunjukkan perkiraan waktu yang realistis untuk setiap aktivitas. PERT (Program Evaluation and Review Technique) adalah teknik manajemen proyek yang menggunakan tiga perkiraan waktu untuk tiap kegiatan yaitu waktu tercepat, waktu terlama, dan waktu paling mungkin. PERT adalah suatu metode yang bertujuan untuk semaksimal mungkin mengurangi adanya penundaan kegiatan. Dari perrhitungan waktu kegiatan yang diharapkan (expected time) diperoleh durasi proyek selama 245 hari untuk menyelesaikan seluruh pekerjaan yang ada dengan tingkat keberhasilan sebesar 99,9 %.Penjadwalan rencana awal proyek membutuhkan durasi selama 270 hari, sedangkan implementasi PERT hanya membutuhkan durasi selama 245 hari. Oleh karena itu, implementasi PERT lebih cepat 25 hari daripada penjadwalan rencana awal proyek.
