Readiness of the Haji Abdoel Madjid Regional General Hospital Batanghari Jambi to Deal Disaster

Disasters are events caused by events or a series of events caused by natural or non-natural. During the period from January to May 2021, there were 1,185 disasters that occurred in Indonesia such as floods, tornadoes, landslides, forest and land fires, earthquakes, tidal waves and droughts. This study aimed to analyse the preparedness of the Haji Abdoel Madjid Batang Hari Regional General Hospital (RSUD HAMBA) Jambi (facing disasters and the COVID-19 pandemic). The research method uses a mix method approach, using the Hospital Safety Index (HSI) forms. The HAMBA Hospital included earthquakes, strong winds, fires, and the COVID-19 pandemic. The struktural safety assessment got an index score of 0.69, non-struktural safety was 0.67, and emergency and disaster management safety got an index score of o.63. Overall, HAMBA Hospital received a safety index of 0.67 which was included in the "A" classification which indicates that HAMBA Hospital is ready to face the COVID-19 disaster and pandemic. HAMBA Hospital is expected to strengthen emergency and disaster management, renovation and addition of rooms and facilities must follow applicable hospital building safety standards.

The Relationship between the Economic Consequences of Accidents and Safety Measures: A Case Study

Background: Accidents impose harmful economic consequences for workers, employers, and society. The present study aimed to evaluate the economic consequences of occupational accidents. Methods: This descriptive-analytical study was conducted in the Iranian Gas Engineering and Development Company in 2020. Data collection tools were a checklist and a researcher-made questionnaire. The reliability of this questionnaire was calculated through Cronbach's alpha coefficient. Data analysis was conducted using SPSS statistical software and the significance level was considered 0.05. Results: The reliability of this questionnaire was estimated at α = 0.87. The average lost work day caused by occupational accidents was 36.67 days and the average cost imposed for each accident was 23.97 million Tomans. The total safety index in the studied environment was calculated at 3.59± 1.01. The results of linear multivariate regression analysis indicated that the cost imposed for each accident has a significant relationship with accident type and accident consequence, level of education, number of workers, training hours, work experience, salary, and total safety index (p <0.05). Conclusion: The findings of this study showed that the economic performance of a company can be affected by individual, occupational, and most importantly safety factors of the company. In addition, such factors are considered as strong predictors for economic safety performance.

SEDRA: Selective Entry Dynamic Risk Assessment A mathematical model to safely keep the borders open during Covid-19

1.AbstractThe Covid-19 pandemic has brought the World to a near standstill for most of 2020 and 2021, causing chaos in international travel, driving many economies into the ground, particularly those largely based on tourism. The lack of standard tools to assist decision makers in structuring a coherent policy to allow foreign passengers into their county and the resulting panic-mode opening/closing the borders on every “new case” outburst or new variant “of concern”, have led several countries to costly and often meaningless decisions based on fear rather than science or logic. This study aims at providing a universal method to safely keep the borders open and allow conditional immigration to foreign passengers according to a “Risk Group” table that includes all the countries reporting data on their Covid-19 situation to the WHO and other organisms. The RG table is recalculated on a weekly basis according to a mathematical model described in this paper, dynamically assessing the status of the pandemic worldwide through the calculation of a “Safety Index” for each country. A prototype algorithm has been implemented in VBA/EXCEL and its results are published bi-weekly on a Github repository.

Implantable collamer lens versus small incision lenticule extraction for high myopia correction: A systematic review and meta-analysis

Purpose To compare the efficacy, safety, predictability and visual quality between implantable collamer lens (ICL) implantation and small incision lenticule extraction (SMILE) for high myopia correction in adults. Methods A systematic review and meta-analysis was conducted. A comprehensive literature search was done based on databases including PubMed, Science Direct, Embase, and the Cochrane Central Register of Controlled Trials. The efficacy index, safety index, changes in Snellen lines of corrected distance visual acuity (CDVA), predictability (difference between post-operative and attempted spherical equivalent error, SER), incidence of halos, and change in higher-order aberrations (HOAs) were compared. Mean difference (MD) and 95% confidence interval (CI) was used to estimate continuous outcomes, risk ratio (RR) and 95%CI was used to estimate categorical outcomes. Results Five observational studies involving 555 eyes were included in this review. Studies’ sample sizes (eyes) ranged from 76 to 197. Subjects’ refraction ranged from -6 diopter (D) to -12D. Study duration of most researches were 6 months or 12 months. Compared to SMILE, ICL implantation showed better efficacy index (MD=0.09, 95%CI:0.01 to 0.16) and better safety index (MD=0.08, 95%CI: 0.00 to 0.16). Compared with SMILE, more ICL-treated eyes gained one or more Snellen lines of CDVA (RR=1.54, 95%CI:1.28 to 1.86), more gained two or more lines (RR=2.09, 95%CI:1.40 to 3.13), less lost one or more lines (RR=0.17, 95%CI:0.05 to 0.63). There was no difference in predictability between two treatments, RRs of predictability of within ±0.5D and ±1D were 1.13 (95%CI: 0.94 to 1.36) and 1.00 (95%CI: 0.98 to 1.02). Compared with SMILE, ICL implantation came with a higher risk of halos [RR=1.79, 95%CI: 1.48 to 2.16] and less increase in total HOAs (MD=-0.23, 95%CI: -0.42 to -0.03). Conclusion Compared with SMILE, ICL implantation showed a higher risk of halos, but equal performance on SER control, and better performance on efficacy index, safety index, CDVA improvement and HOAs control. Overall, ICL implantation might be a better choice for high myopia correction in adults.

Myopic Correction with Iris-Fixated Phakic Intraocular Lenses: Twelve-Year Results

Purpose. To evaluate a 12-year follow-up of myopic patients after iris-fixated phakic intraocular lenses (IF pIOLs) implantation. Setting. Ophthalmology Department, Military University Hospital in Prague (Czech Republic). Design. Single-center retrospective cohort study. Methods. We describe the results of a cohort study that included 85 eyes of 46 myopic patients who underwent implantation of Verisyse myopia, Veriflex, and Verisyse myopia toric (all Abbott Medical Optics, Inc.) intraocular lenses. Refractive functions and adverse events were assessed preoperatively, at 6 months, and 1, 2, 5, and 12 years after IF pIOL implantation. Results. Mean spherical equivalent was measured as −9.37 ± 2.87 D, 0.14 ± 0.61 D, and −0.42 ± 1.08 D, preoperatively, at 6 months and 12 years postoperatively, respectively. There was a significant reduction in the cylinder after surgery. At 12 years postoperatively, 90% of eyes had uncorrected distance visual acuity (UDVA) of 20/40 and 64% of 20/20. The safety index was 1.10 for the whole postoperative follow-up period. We found cataract formation in 3 eyes (3.5%). The endothelial cells loss (EC loss) directly caused by IF pIOL implantation was 6.0%, 8.10%, 12.8%, and 11.9%, at 1, 2, 5, and 12 years, respectively. In our cohort, 95% of eyes lost a higher percentage of EC than would be expected from a physiological loss at 12 years postoperatively. We found a significant negative interaction between preoperative pachymetry and EC loss, indicating that the lower pachymetry leads to a faster decline in endothelial cells density (ECD). IF pIOL re-enclavation was found in 28% of eyes. 7% of subluxations were caused by trauma. The mean time of nontraumatic re-enclavation was 6 years postoperatively. Conclusions. The study confirmed the advantages of IF pIOL implantation due to rapid visual recovery and stable visual function over the 12-year follow-up and also showed the influence of lower corneal pachymetry regarding EC loss.
