Prediction Analysis of Laboratory Equipment Depreciation Using Supervised Learning Methods

Asset management in Indonesia still poses problems in terms of securing state-owned property. These concerns make it difficult for analysts to predict laboratory equipment depreciation. Therefore, this research aims to create a new model to address this issue. Additionally, to support laboratory managers in gaining insights, a technology-based framework in the form of a laboratory equipment depreciation prediction model has been developed. A new model has been created in this research, which integrates supervised learning models with linear regression algorithms, and subsequently employs a waterfall system development approach. The testing results of the model for predicting laboratory equipment depreciation showed a high level of accuracy, reaching 93%. Furthermore, the comparison between the prediction model and the laboratory equipment data tested directly by technicians demonstrated an accuracy rate of 100%. Finally, the numerical results demonstrate that our framework provides a valuable solution to the difficulties in predicting laboratory equipment depreciation, offering an innovative and practical approach to laboratory equipment maintenance.

The laboratory is a place to conduct scientific research, experiments, measurements, or scientific training. FMIPA UNNES has several laboratories distributed in each department to support student lectures. Through the implementation of practicum in the laboratory, students are expected to be able to find a concept, foster scientific attitudes, and critical thinking skills. Good laboratory management is expected to be able to utilize laboratory resources effectively and efficiently. Laboratory equipment must be ensured to function properly and be ready to be used for practicum. To support this, it is necessary to monitor the condition of the equipment and immediately repair the equipment if any damage is found. The current obstacle is monitoring tool repairs manually, so there are shortcomings such as poor documentation, and equipment conditions that cannot be monitored online. In this study, an information system for monitoring the maintenance of laboratory equipment in the departments in the FMIPA UNNES environment will be built. The research method begins with a literature study, initial data collection and observation, EAP-based system design, system testing, system analysis, and system evaluation. This study uses the SDLC (System Development Life Cycle) approach which is used to develop a product for the Monitoring Information System for the Maintenance of Laboratory Equipment. Testing is done using black box testing. From the results of development and testing, it can be concluded that the system can be used to simplify the process of managing laboratory equipment with a UAT value of 88% suitable for use.

The learning environment as a predictor of higher order thinking skills

The learning environment is one of the elements that will influence higher-order thinking skills (HOTS). The purpose of this study was to test the influence of the learning environment on HOTS. The researcher selected 82 forms two students from two secondary schools in Kuala Nerus, Terengganu, Malaysia, as the study sample. The researcher has adopted a set of questionnaires that have been developed by previous researchers and a questionnaire developed by the researcher himself. Multiple regression analysis has found that material environment and cooperation between students’ constructs are predictors of HOTS. Therefore, the Ministry of Education Malaysia as a stakeholder in the education sector in the country is expected to: i) Allocate ample expenditure to purchase and maintain all laboratory equipment and materials and ii) Organize workshops on the maintenance of laboratory equipment and materials for laboratory assistants in high school to ensure they are always in the best possible condition. The researcher suggested that future studies focus on producing maintenance modules for the materials and science equipment for laboratory assistants’ use. It is hoped that with this module, the focus on improving Malaysian students’ HOTS will be easily achieved by 2025.

Adding the Team into T1 Translational Research: A Case Study of Multidisciplinary Team Science in the Evaluation of Biomarkers of Prostate Cancer Risk and Prognosis.

Given translational research challenges, multidisciplinary team science is promoted to increase the likelihood of moving from discovery to health effect. We present a case study documenting the utility of multidisciplinary team science in prostate cancer tissue biomarker validation. We used primary data generated by a team consisting of a pathologist, cancer biologists, a biostatistician, and epidemiologists. We examined their contributions by phase of biomarker evaluation to identify when, through the practice of team science, threats to internal validity were recognized and solved. Next, we quantified the extent of bias avoided in evaluating the association of Ki67 (immunohistochemistry), stromal cell telomere length (fluorescence in situ hybridization), and microRNA (miRNA) (miR-21, miR-141, miR-221; quantitative RT-PCR) with prostate cancer risk or recurrence in nested case-control studies. Threats to validity were tissue storage time (Ki67, miRNA) and laboratory equipment maintenance (telomeres). Solutions were all in the data analysis phase and involved using tissue storage-time specific cutpoints and/or batch-specific cutpoints. Bias in the regression coefficient for quantiles of each biomarker ranged from 24% to 423%, and the coefficient for the test for trend ranged from 15% to 910%. The interpretation of the associations changed as follows: Ki67, null to positive; stromal cell telomere length, null to positive; miR-21 and miR-141 remained null; miR-221, weak to moderate inverse. In this case study, we documented the inferential benefits of multidisciplinary team science when the team's collaboration and coordination led to the identification of threats to validity and the implementation of appropriate solutions.

Technical Efficiency in Public Health Facilities in Meru County: Dea Analysis

Background: Healthcare provision is one of the key strategic Development Goals to be achieved by the year 2030. Governments have directed a lot of financial resources towards this purpose in an effort to meet the threshold set out by the WHO to ensure provision of quality healthcare and access by all citizens. Objectives: To measure the technical efficiency levels in the public health system in Meru County in Kenya and investigate determinants of the technical efficiencies among the Decision Making Units (DMUs). Data analysis: Analysis reported in this paper is based on the data from Meru County health centres. It consisted of 17 Decision Making Units (DMUs) with inputs as clinical staff and other staff while outputs were maternal care visits and other visits. Dummy variables considered were; education, training, gender of head nurse and laboratory. Analysis was done by Data Envelopment Analysis (DEA). Results: The analysis revealed that average technical efficiency in the sample was 45.2%. This findings suggest that the existing health care services can be increased by up to 54.8% without providing additional resources to the frontline health facilities- a near replication of findings originally reported earlier. Tobit regression results show that gender of the facility manager and the availability of a laboratory at a facility are the main determinants of efficiency. Conclusion and recommendation: Policies designed to improve health care delivery should focus on upgrading laboratory services and skills of facility heads, especially managerial abilities of female nurses. Efforts need to be directed towards enhancing efficiency such as training staff in management practices, maintenance of laboratory equipment, gender composition of staff should equally be considered. Focus on preventive healthcare such as regular check-ups would lower risks of severe or resistant cases that are difficult to treat in order to increase efficiency. Creation of conducive waiting and smooth flow of patient cues in the health facility would also increase technical efficiency of the facility.

Challenges of the Unified Health System: present status of public laboratory services in 31 cities of Minas Gerais, Brazil

Introduction: Modifications in the Brazilian Unified Health System (SUS) have led to a significant improvement in the national health indexes. However, some challenges still need to be faced, especially concerning SUS patients' access to high-quality laboratory support services. Objective: To evaluate the present status of laboratory services in SUS in 31 cities of Minas Gerais, Brazil, between 2008 and 2011. Material and method: This analysis was performed through data from the Information Technology Department of SUS (DATASUS) and through interviews with local public health managers with structured questionnaires. Results: Among all the studied cities, 21 had their own laboratory, 90.2% of which were in precarious conditions, not meeting the requirements established by the legislation in force, and employing inappropriate procedures and techniques, in addition to using obsolete equipment. The range of available laboratory tests was limited, what demanded the services of supporting laboratories. None of the evaluated laboratories developed any systematic activity on quality management, including control of analytical quality, maintenance of laboratory equipment, calibration and performance evaluation of critical equipment, continuing education programs, and safety and biosecurity. Conclusion: The effective role of laboratory test results in medical decision is unquestionably impaired, risking the safety of SUS patients. The present work reveals the deficiencies of public laboratory services in Minas Gerais, and proposes a new management model, which is able to associate operational quality, technological development and optimization of human and material resources with higher productivity.

The Case for In-House Laboratory Equipment Maintenance

Healthcare technology management (HTM) professionals have taken a hands-off approach to laboratory equipment maintenance. Typically, there isn't much of such equipment in the inventory, and the cost to train personnel to service can be a hurdle to making the move to in-house maintenance. Additionally, in some cases the equipment has been provided free of charge in return for a long-term contract for expendable supplies used to operate the equipment. Finally, regulatory oversight from College of American Pathologists (CAP) or other agencies can discourage in-house maintenance.However, I strongly encourage all HTM professionals to help bring laboratory maintenance back in-house. While there may be some short-term pain, the potential for long-term benefits is greater. There are three main reasons to make the move. First, we in the HTM field are losing an important technical skillset by not maintaining laboratory equipment. Second, because of this diminishing skillset, the contract cost will inevitably rise due to supply and demand and manufacturers being able to control the supply. Third, we are building walls between biomedical equipment technicians (BMETs) and laboratory technicians, and that's not healthy.In-house maintenance technicians or BMETs, have traditionally, only worked on the most basic laboratory equipment. To address this lack of experience, consider sending your in-house technicians out with the manufacturer's field service engineers (FSEs) to observe how to maintain the equipment. There may be a short-term cost in slightly decreased productivity for the BMET team, but the long-term benefit is that your in-house technicians will expand their skillsets. Additionally, they may discover that some of the equipment can be maintained in-house, reducing the contract cost for your hospital.If manufacturers continue to observe that HTM departments are reluctant to bring the laboratory maintenance in-house, the cost for contract maintenance will rise. Analysis by HTM professionals to determine the cost effectiveness of maintenance contracts will become a paperwork drill.HTM professionals need to think of options other than maintenance contracts with outside vendors. What are the total costs of the maintenance contracts for laboratory equipment? Once that is calculated, determine if it is cheaper to hire a technician to take care of the laboratory maintenance. In a medium to large hospital, I would be surprised if the savings is not there. If possible, standardize all the equipment under one manufacturer. Consider bringing in a FSE who is trained in how to service the laboratory equipment. While the FSE may not have the usual background of an associate's degree or military training, his or her experience and training by the manufacturer could lead to savings.In conclusion, I encourage you to find ways to bring laboratory maintenance in-house. Be creative, find cost-saving methods that will increase response time, and increase the knowledge base of the in-house HTM. At least consider the inclusion of laboratory maintenance as part of the overarching HTM community.

Analysis of the Effects of Phasing Out IVF Laboratory Scheduled Maintenance Periods

Many IVF programs schedule patients in series to accommodate Embryology laboratory equipment maintenance, calibration and certification. A down side to these scheduled maintenance periods is that patients can be inconvenienced and treatment delayed. We have thus modified our scheduling process over the past decade from running four clinical series of patients per year down to three, and now to only two maintenance periods. We undertook this study to determine if the prolonged laboratory series resulted in any variation on patient success rates. Clinical and laboratory data from our electronic medical records database were analyzed for all fresh IVF cases (n= 6826) during 19 series, ranging from 44-163 days in length between 01/01/05 and 12/31/10. ANOVA and biserial correlation were performed to analyze for any association between patient success rates (defined as the presence of fetal heart beats) and the length of each series. Additional analysis was performed to determine if success rates were different during the last two weeks of each series. Days of series length varied significantly, but did not show any correlation with success rates across the entire study period (r=0.00, P=0.96) or during each of the different series lengths (Table). When analyzing across all 19 series, the pregnancy rate of patients treated during the last 2 weeks was not different from the rest of the series (43.0% vs. 44.5%, P=0.58). However when analyzed between series, the pregnancy rate was different during the last two weeks within 2 individual series: #18 (16.1% higher, P=0.04) and #30 (19.3% lower, P=0.01). We demonstrated that the length of a series does not impact a patient's chance of IVF success. The pregnancy rates observed towards the end of a series were not significantly different from the rest of the series. In a high quality laboratory with daily cleaning, vigilant equipment maintenance, tightly controlled QA/QC protocols and experienced personnel there should not be a need for frequent scheduled “down time.”TableSeries 12-19 (4 maintenance/yr)Series 20-28 (3 maintenance/yr)Series 29-30 (2 maintenance/yr)p-valueMean Days/Series65 ± 1498 ± 6157 ± 8<0.01Success Rate %44 (835/1916)43 (1580/3678)44 (536/1232)0.88 Open table in a new tab

Laboratory equipment maintenance: A critical bottleneck for strengthening health systems in sub-Saharan Africa?

Properly functioning laboratory equipment is a critical component for strengthening health systems in developing countries. The laboratory can be an entry point to improve population health and care of individuals for targeted diseases - prevention, care, and treatment of TB, HIV/AIDS, and malaria, plus maternal and neonatal health - as well as those lacking specific attention and funding. We review the benefits and persistent challenges associated with sustaining laboratory equipment maintenance. We propose equipment management policies as well as a comprehensive equipment maintenance strategy that would involve equipment manufacturers and strengthen local capacity through pre-service training of biomedical engineers. Strong country leadership and commitment are needed to assure development and sustained implementation of policies and strategies for standardization of equipment, and regulation of its procurement, donation, disposal, and replacement.

Laboratory equipment maintenance contracts.

The increasing level of technical sophistication and complexity found in clinical laboratory instrumentation today more than ever demands careful attention to maintenance service needs. The time-worn caution for careful definition of requirements for acquisition of a system should also carry over to acquisition of maintenance service. Guidelines are presented for specifications of terms and conditions for maintenance service from the perspective of the laboratorian in the automated clinical laboratory.
