Effect of implementing quality control management in the treatment of severely injured patients: a retrospective cohort study in a level I trauma center in China

BackgroundThis study aimed to review the impact of quality control management on the treatment of severely injured patients.MethodsA retrospective analysis was conducted on patients with severe injury (injury severity score [ISS] ≥ 16) between January 1, 2018 and February 1, 2020. The selected patients were stratified as follows. The patients who were admitted prior to the implementation of quality control management—from January 1 to December 31, 2018—were assigned to the PRE group; the POST group included patients who were admitted after the implementation—from February 1, 2019 to February 1, 2020. Quality control management was implemented from January 1, 2019 to January 31, 2019. Parameters were compared to account for differences in terms of demographics, surgical procedures, results of process quality, and 72-h mortality.ResultsThis study included 599 patients (PRE group: 212 males and 86 females; POST group: 228 males and 73 females; P = 0.20). The extent of document completion was 97.3 and 100% in the PRE and POST groups, respectively (P < 0.001). There was no delay in the arrival of the trauma surgeons or the multidisciplinary team after implementation. However, following implementation of quality control management, there was a significant reduction in the duration of basic diagnostics, time until receipt of laboratory data, time until first computed tomography scan, time until intubation, and time until an emergency operation (P < 0.05). The deaths were caused by severe head injury (PRE: 5.4%, POST: 4%), hemorrhagic shock (PRE: 2.4%, POST: 0.7%), multiple-organ failure (PRE: 1.0%, POST: 0.3%), or other causes (PRE: 0.7%, POST: 0.0%). The 72-h mortality decreased after the implementation of quality control management (PRE vs. POST groups: 9.4 vs. 5.0%, P = 0.04).ConclusionsThe implementation of quality control management resulted in decreased time to critical interventions, improved patient care efficiency, and reduced early mortality. We recommend that this approach be replicated at other trauma centers in China.

Establishment and Evaluation of an Internal Quality Control Method for ESR Relays.

ObjectiveThis study establish and evaluate an internal quality control system for erythrocyte sedimentation rate (ESR) by a “relay” mode based on samples from relevant patients.MethodsThe method for establishing a new internal quality control system for ESR by a “relay” mode based on patient’s samples was executed from February 2021 to July 2021. In this paper, a total of 219 outpatients were recruited for ESR determination, and their blood samples were stored at 4 °C or room temperature for 24 h. Subsequently, the samples were re-measured for ESR, and the re-measured values were compared with the initial values. The patient samples (15±1mm/h and 50±3mm/h) were selected after the TEST1 ESR analyzer was calibrated, and were stored overnight at 4 °C and measured again the following day. The percentage deviation was determined and entered into the quality control management module for internal quality control. Next, we analyzed the median distribution trend of the patients’ ESR values measured by our laboratory every day over five months, as well as the external quality assessment (EQA) results for ESR obtained from the National Center for Clinical Laboratories (NCCL).ResultsThe ESR of the room temperature samples after 24 h of storage had significantly decreased (P=0.001), while there was no noticeable difference for those stored at 4 °C (P=0.197). Results of the internal quality control in March were satisfactory, and there was no significant deviation in the median ESR relay results within five months. Besides, the EQA results for the ESR data obtained from NCCL were excellent.ConclusionAs a precise and practical new method, the ESR relay internal quality control method can be used to scientifically determine the stability and accuracy of the TEST1 ESR analyzer.

Energy-efficient long range wide area network for construction industry applications

Long Range (LoRa) technology is inevitable in the Internet of Things applications for the construction industry due to the large transmission range. Accordingly, this emerging technology is being used in many civil engineering applications such as water quality control, equipment tracking, etc., and the use of this technology is likely to multiply in the coming years. Therefore, the energy efficiency of this system should be investigated to reduce its environmental impact, which is lacking in previous investigations. This paper explores the effect of transmission parameters on power consumption and proposes a scheme for controlling transmission parameters to improve the energy efficiency of LoRa end nodes. The effectiveness of the proposed scheme is demonstrated through a case study on a real-time monitoring system based on LoRa for the compressive strength of concrete at early ages which is crucial for quality control and construction management.

FIBER-ML, an Open-Source Supervised Machine Learning Tool for Quantification of Fibrosis in Tissue Sections

Pathologic fibrosis is a major hallmark of tissue insult in many chronic diseases. Although the amount of fibrosis is recognized as a direct indicator of the extent of disease, there is no consentaneous method for its quantification in tissue sections. This study tested FIBER-ML, a semi-automated, open-source freeware that uses a machine-learning approach to quantify fibrosis automatically after a short user-controlled learning phase. Fibrosis was quantified in sirius red-stained tissue sections from two fibrogenic animal models: acute stress-induced cardiomyopathy in rats (Takotsubo syndrome-like) and HIV-induced nephropathy in mice (chronic kidney disease). The quantitative results of FIBER-ML software version 1.0 were compared with those of ImageJ in Takotsubo syndrome, and with those of inForm in chronic kidney disease. Intra- and inter-operator and inter-software correlation and agreement were assessed. All correlations were excellent (>0.95) in both data sets. The values of discriminatory power between the pathologic and healthy groups were <10-3 for data on Takotsubo syndrome and <10-4 for data on chronic kidney disease. Intra-operator agreement, assessed by intra-class coefficient correlation, was good (>0.8), while inter-operator and inter-software agreement ranged from moderate to good (>0.7). FIBER-ML performed in a fast and user-friendly manner, with reproducible and consistent quantification of fibrosis in tissue sections. It offers an open-source alternative to currently used software, including quality control and file management.

Dual spectroscopic detection of THz energy modes of critical chemical compounds

Precise identification and sensing of organic and inorganic molecular systems are key factors in several applications in present industrial and scientific domains. While high energy modes, due to electronic interactions, are mostly impervious to the initial thermodynamic or chemical conditions, the low energy modes are sensitive to such alterations which makes them suitable for quality control purpose with sensitive spectral identification methods. Here we report for the first time, several low frequency peaks of specific nitrogen-based compounds and their derivatives, using the dual spectroscopic approach of Terahertz Time-Domain Spectroscopy (THz-TDS) and THz Raman Spectroscopy (THz-RS). Two different isomeric molecular systems have also been investigated to assess both the selectivity and specificity of low energy modes in their identification and spectral correlation in terms of molecular interactions. This information of low frequency modes can be utilized readily by pharmaceutical and agri-food industries, chemical engineering and crystal growth communities in identification, detection, quality control and industrial waste management.

Research, development, and evaluation of the practical effect of a storage inflow and outflow management system for consumables in the endocrinology department of a hospital

BackgroundThis study was designed for the research and development (R&D) and application of a storage inflow and outflow management system enabling departments to perform efficient, scientific, and information-based consumable management.MethodsIn the endocrinology department of a hospital, expert and R&D teams in consumable management were set up, and an information-based storage inflow and outflow management system for consumables was designed and developed. The system was operated on a personal computer and was divided into three modules: public consumables, bed consumables, and quality control management. The functions of the system included storage inflow and outflow, early warnings, response to user queries, and statistics on consumables. Data were derived from the hospital information system (HIS,ZHIY SOFTWARE HIS VERSION4.0) and a questionnaire survey. Economic indicators, work efficiency of consumable management, nurse burnout, consumable stockroom management, and staff satisfaction were compared under manual management, Excel-based management, and the consumable storage inflow and outflow management system. The results of the questionnaire were analysed using the R software, version 4.1.0.ResultsDates were obtained from manual management, Excel-based management and the consumable storage inflow and outflow management system. Under these three methods, the daily prices of department consumables per bed were 53.43 ± 10.27 yuan, 38.65 ± 8.56 yuan, and 31.98 ± 7.36 yuan, respectively, indicating that the new management system reduced costs for the department. The time spent daily on consumable management was shortened from 119.5 (106.75, 123.5) min to 56.5 (48.5, 60.75) to 20 (17.25, 24.25) min. Nurses’ emotional fatigue and job indifference scores, respectively, decreased from 22.90 ± 1.65 and 8.75 ± 1.25 under manual management to 19.70 ± 1.72 and 6.90 ± 1.37 under Excel-based management and to 17.20 ± 2.04 and 6.00 ± 1.30 under the novel system; the satisfaction of the warehouse keeper and collection staff, respectively, increased from 76.62% and 80.78% to 91.6% and 90.5% to 98.8% and 98.5% under the three successive systems.ConclusionsThe storage inflow and outflow management system achieved produced good results in the storage and classification of consumables.

Concrete Production and Curing with Recycled Wastewater: A Review on the Current State of Knowledge and Practice

A number of factors have combined to put excessive pressure on the finite available freshwater resources. These include increasing population, rapid urbanization, industrialization, changed land pattern usage and land cover, change in the overall ecological system, and increased temperature and unscientific compromises in the extraction of water are at alarming threshold putting pressure on the finite available freshwater resources. As a result, many countries have been stressed or are at the verge of being stressed. The problem is worsened day by day by prolonged drought, unchecked discharge of untreated or partially treated wastewater to the freshwater reservoirs and lack of proper water quality control measures and management. Many initiatives such as Zero Liquid Discharge of industrial wastewater into freshwater bodies such as reservoirs, lakes, and ponds, and the use of recycled wastewater for irrigation and domestic purposes have started to be embraced as measures to put a check on the fast depleting freshwater resources for sustainable socio‐economic development. The construction industry is the second largest consumer of freshwater just after agriculture. Concreting alone consumes, annually, over one trillion m3 of freshwater globally while the concept of the use of wastewater and/or recycled water in the concrete‐making processes is yet to be adopted. Hence, this paper presents a general review of the current state of knowledge and practice on concrete production and curing using recycled wastewater from industrial, commercial, and domestic activities. An extensive review of the existing literature revealed that recycled water is fit for concrete production and curing purposes. The observations made are based on the assessment of wastewater quality parameters and their impacts on some selected concrete properties such as initial setting time and compressive strength. Due to scanty research on the impacts of varying concentrations of different ingredients in any questionable water on selected properties of reinforced concrete and its durability, thus, further research is recommended.

Fluxes of H2S and SO2 above a subtropical forest under natural and disturbed conditions induced by temporal land-use change

Hydrogen sulfide (H2S) is one of predominant biogenic sulfur gases, influencing aerosol formation and climate change. There is considerable uncertainty of the global budget of H2S due to limited field data, especially in subtropical forests. In addition, an interaction between soil-emitted H2S and ambient sulfur dioxide (SO2) might exist within forest ecosystems. In this study, the aerodynamic gradient method was applied to consecutively measure H2S and SO2 fluxes above a subtropical forest canopy in Southwest China under natural and disturbed conditions induced by temporal land-use changes. The average H2S concentration and flux under natural conditions were 0.79 ± 0.07 ppbv and 0.04 ± 0.01 g S m−2 yr−1, respectively. The emission was larger than that in most croplands and freshwater wetlands. Vegetation emissions might account for about 26% of the total forest H2S emissions at this site. The deposition of SO2 was likely balanced by H2S oxidization under the forest canopy, with the mean concentration and net flux as 1.23 ± 0.11 ppbv and −0.03 ± 0.10 g S m−2 yr−1, respectively. Under disturbed conditions with soils excavation and scattering on the forest floor, simultaneously high emissions of H2S and SO2 were observed above the canopy, reaching 5.78 ± 0.16 and 1.60 ± 0.87 g S m−2 yr−1, respectively. This suggested that land-use change in subtropical forests might lead to release of legacy S in subsoils to the atmosphere in the form of H2S and SO2. Regarding the widely documented large S accumulation and expanding deforestation across subtropical forests, potentially high emissions of H2S and SO2 from subtropical forests should be carefully considered in regional air quality control and forest management.
