RESUMO

Substantial investments into laboratories, notably sophisticated equipment, have been made over time to detect emerging diseases close to their source. Diagnostic capacity has expanded as a result, but challenges have emerged. The Equipment Management and Sustainability Survey was sent to the Veterinary Services of 182 countries in mid-2019. We measured the status of forty types of laboratory equipment used in veterinary diagnostic laboratories. Of the 68,455 items reported from 227 laboratories in 136 countries, 22% (14,894/68,455) were improperly maintained, and 46% (29,957/65,490) were improperly calibrated. Notable differences were observed across World Bank income levels and regions, raising concerns about equipment reliability and the results they produce. Our results will advise partners and donors on how best to support low-resource veterinary laboratories to improve sustainability and fulfill their mandate toward pandemic prevention and preparedness, as well as encourage equipment manufacturers to spur innovation and develop more sustainable products that meet end-users' needs.

RESUMO

In recent years, the unmanned aerial vehicle (UAV) remote sensing technology has been widely used in the planning, design and maintenance of urban distributed photovoltaic arrays (UDPA). However, the existing studies rarely concern the UAV swarm scheduling problem when applied to remoting sensing in UDPA maintenance. In this study, a novel scheduling model and algorithm for UAV swarm remote sensing in UDPA maintenance are developed. Firstly, the UAV swarm scheduling tasks in UDPA maintenance are described as a large-scale global optimization (LSGO) problem, in which the constraints are defined as penalty functions. Secondly, an adaptive multiple variable-grouping optimization strategy including adaptive random grouping, UAV grouping and task grouping is developed. Finally, a novel evolutionary algorithm, namely cooperatively coevolving particle swarm optimization with adaptive multiple variable-grouping and context vector crossover/mutation strategies (CCPSO-mg-cvcm), is developed in order to effectively optimize the aforementioned UAV swarm scheduling model. The results of the case study show that the developed CCPSO-mg-cvcm significantly outperforms the existing algorithms, and the UAV swarm remote sensing in large-scale UDPA maintenance can be optimally scheduled by the developed methodology.

RESUMO

Protocols for the sanitation and maintenance of point-of-care ultrasound (US) equipment are lacking. This study introduces the CLEAR protocol (clean, locate, energize, augment supplies, and remove patient identifiers) as a tool to improve the readiness of US equipment, termed US equipment homeostasis. The state of US equipment homeostasis in the emergency department of a single academic center was investigated before and after implementing this protocol, with an improvement in outcomes. These findings demonstrate that the CLEAR protocol can improve US homeostasis. CLEAR can function as a teaching tool to promote homeostasis as well as a checklist to assess compliance.

RESUMO

OBJECTIVE: To evaluate oxygen flowmeters for accuracy and precision, assess the effects of cleaning and assess conformity to the American Society for Testing Materials (ASTM) standards. STUDY DESIGN: Experimental study. METHODS: The flow of oxygen flowmeters from 31 anesthesia machines aged 1-45 years was measured before and after cleaning using a volumetric flow analyzer set at 0.5, 1.0, 2.0, 3.0, and 4.0 L minute-1. A general linear mixed models approach was used to assess flow accuracy and precision. RESULTS: Flowmeters 1 year of age delivered accurate mean oxygen flows at all settings regardless of cleaning status. Flowmeters ≥5 years of age underdelivered at flows of 3.0 and 4.0 L minute-1. Flowmeters ≥12 years underdelivered at flows of 2.0, 3.0 and 4.0 L minute-1 prior to cleaning. There was no evidence of any beneficial effect of cleaning on accuracy of flowmeters 5-12 years of age (p > 0.22), but the accuracy of flowmeters ≥15 years of age was improved by cleaning (p < 0.05). Regardless of age, cleaning increased precision, decreasing flow variability by approximately 17%. Nine of 31 uncleaned flowmeters did not meet ASTM standards. After cleaning, a different set of nine flowmeters did not meet standards, including three that had met standards prior to cleaning. CONCLUSIONS: Older flowmeters were more likely to underdeliver oxygen, especially at higher flows. Regardless of age, cleaning decreased flow variability, improving precision. However, flowmeters still may fail to meet ASTM standards, regardless of cleaning status. CLINICAL RELEVANCE: Cleaning anesthesia machine oxygen flowmeters improved precision for all tested machines and partially corrected inaccuracies in flowmeters ≥15 years old. A notable proportion of flowmeters did not meet ASTM standards. Cleaning did not ensure that they subsequently conformed to ASTM standards. We recommend annual flow output validation to identify whether flowmeters are acceptable for continued clinical use.

RESUMO

OBJECTIVE: dimensional guidelines for bedrails have been developed to minimise the risk of patient entrapment within the bed. We examined whether bedrails in a large Irish teaching hospital complied with these standards. DESIGN AND SETTING: survey of 60 accessible beds in six hospital wards. METHODS: a specialised cone and cylinder tool that mimics the size and weight of a small adult neck and head was used to determine gaps in the four zones most associated with entrapment. RESULTS: the number of failures for each zone was 15 beds for zone 1 (any space between the perimeters of the rail); 42 beds for zone 2 (the space under the rail); 41 beds for zone 3 (the space between the inside surface of the bedrail and the mattress) and 13 beds for zone 4 (the space between the mattress and rail at the end of the rail). Failures were more common with hydraulic adjusted than with electric profiling beds. Mattresses that were the wrong size (usually too narrow) or too soft and bedrails that were loose or were poorly maintained accounted for many failures. CONCLUSION: many beds used in our hospital did not comply with dimensional standards to minimise entrapment risks. This emphasises the need for careful selection of patients for whom bedrails are to be used as well as the need for monitoring and maintenance of bed systems.

RESUMO

While a number of new vaccines have been rolled out across the developing world (with more vaccines in the pipeline), cold chain systems are struggling to efficiently support national immunization programs in ensuring the availability of safe and potent vaccines. This article reflects on the Clinton Health Access Initiative, Inc. (CHAI) experience working since 2010 with national immunization programs and partners to improve vaccines cold chains in 10 countries-Ethiopia, Nigeria, Kenya, Malawi, Tanzania, Uganda, Cameroon, Mozambique, Lesotho and India - to identify the root causes and solutions for three common issues limiting cold chain performance. Key recommendations include: Collectively, the solutions detailed in this article chart a path to substantially improving the performance of the cold chain. Combined with an enabling global and in-country environment, it is possible to eliminate cold chain issues as a substantial barrier to effective and full immunization coverage over the next few years.

RESUMO

Many oral and maxillofacial surgical procedures are done in an office-based setting, with many oral and maxillofacial surgeons involved in oversight of equipment maintenance. Goals in equipment management are to prevent harm to patients and staff, stay compliant with current regulations, and increase equipment longevity. This article covers the safety, maintenance, and inspection related to electrical equipment used in the treatment of patients, autoclaves, radiograph machines, nitrous oxide and oxygen medical gases, and required back-up power and lighting. An office should always follow manufacturer's recommendations regarding maintenance and inspection and document policies and monitoring so compliance can be assured.

RESUMO

Linear accelerator downtimes are common and problematic in many African countries and may jeopardise the outcome of affected radiation treatments. The predicted increase in cancer incidence and prevalence on the African continent will require, inter alia, improved response with regard to a reduction in linear accelerator downtimes. Here we discuss the problems associated with the maintenance and repair of linear accelerators and propose alternative solutions relevant for local conditions in African countries. The paper is based on about four decades of experience in capacity building, installing, commissioning, calibrating, servicing and repairing linear accelerators in Africa, where about 40% of the low and middle income countries in the world are geographically located. Linear accelerators can successfully be operated, maintained and repaired in African countries provided proper maintenance and repair plans are put in place and executed.

RESUMO

Since the outbreak of Novel Coronavirus Pneumonia(NCP), hospitals have taken the fight against the virus as its own responsibility, and keep standing in the front line of epidemic prevention and control. The continuous input of anti-epidemic forces in hospitals also brings challenges to the medical supplies support, including the management of protective supplies and the maintenance of medical equipment. In the face of increasing security pressure, the medical materials support team broke the game on multiple fronts. Firstly, the team implements active material procurement strategy, sets material distribution priority according to risk level, releases materials uniformly based on stock and use, and implements traceability management of donated materials to ensure material supply. Secondly, centralized allocation management of equipment, emergency installation, advanced maintenance and emergency maintenance work is effectively completed. Thirdly, disinfection strategies for items and equipment are developed safely and effectively with the aid of disinfection equipment functions. At last, personnel management and training have been strengthened. These measures have provided strong support for the orderly prevention and control of the epidemic.
