RESUMEN
Background: It is essential for any health-care facility, regardless of its size, to implement a maintenance programme for medical equipment. The maintenance not only has a positive impact on the safety and effectiveness of healthcare technology, but also increases the lifetime of equipment and thus helps to save scarce investment resources. It also enhances the demand for health services. Demand for services availability is crucial of functioning healthcare technology.Methods: A comprehensive descriptive study of the maintenance of equipment at a tertiary care corporate hospital in India from January 2012 to May 2012. A convenient sampling method was used to capture data from Key Participants which included two categories of staff viz technicians and managers/administrators. There were 40 technicians and 10 managers who responded to the questionnaire. Both the primary and secondary sources of data were used.Results: Breakdown data analysis showed that the major cause of breakdown was human errors. About 40% of breakdown that occurred in the hospital was mainly because of manual errors followed by electrical and mechanical issues. Average down time for the time period of 5 months came to around 19 hours, which was quite high. Analysis of KAP questionnaire showed that about 55% technicians were not having the educational qualification required for handling the medical equipment, about 15% were not given training at the time of purchase of the equipment. Similarly, few managers were not aware about maintenance practices and importance of maintenance management for smooth and efficient functioning.Conclusions: Good and effective maintenance practices can reduce the cost of maintenance of equipment that arises due to breakdown. The training of equipment users and maintenance managers reduces the equipment downtime. To reduce the possibility of equipment malfunction following service or repair, all personnel involved in maintaining and servicing equipment should be trained.
RESUMEN
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.

RESUMEN
Objetivo: Identificar as implicações da não manutenção dos equipamentos hospitalares na qualidade do atendimento cirúrgico. Método: Trata-se de uma pesquisa quantitativa, exploratória, descritiva, observacional, realizada em um hospital filantrópico do interior de Minas Gerais. Aplicou-se a técnica de observação direta e a avaliação de registros de manutenção preventiva e corretiva dos equipamentos cirúrgicos. Resultados: Durante o período de observação, verificou-se que os equipamentos que mais apresentaram falhas durante a cirurgia foram: bisturi elétrico, intensificador e foco cirúrgico. Os dados de funcionalidade e manutenção dos equipamentos foram comparados com recomendações do fabricante e com a literatura científica. Conclusão: A não manutenção dos equipamentos cirúrgicos pode prolongar a recuperação pós-operatória, aumentar a morbidade e a mortalidade e levar a um impacto financeiro desnecessário para a instituição. Espera-se que os resultados deste estudo possam motivar a equipe multiprofissional à realização da manutenção preventiva dos equipamentos antes das cirurgias.

Background: Medical equipments are necessary to effectively monitor, treat and support the care of patients by doctors in the management of their medical conditions. Proper maintenance affects the performance and safety of equipment. As equipments are part of health care provision in hospital, it is necessary to have well planned and managed equipment maintenance system in the organization. Aim: The study revealed the medical equipment maintenance system in Physiology Department of tertiary care government teaching institute. Material and methods: A retrospective observational study, during February to June 2014 of fifty two equipments costing more than 10,000 rupees was done for their maintenance system in the department. Information about equipment was collected by onsite inspection and departmental equipment records in structured proforma. Results: In the study, 45 mechanical and 7 electrical equipments costing less than 100,000 rupees were evaluated. It was found that 94.2% equipments did not have any service contract. From time of installation in the department it was found that most equipment i.e. 53.8% had crossed the life period of 15 years. Maximum i.e 85.7% electrical equipments had crossed their average life period. There was no proper maintenance of logbook and non availability of the user manual by the side of 84.6% of the equipments in department. Service history in worksheet of all 52 instruments was not recorded, post warranty maintenance in all equipments was by local personals only which was needed in 90.4% equipments. Out of equipments needing the maintenance and repair, it was corrective type in 98.2% times and reactive type in 1.8% times. There was no special training of the technicians about the maintenance of equipments. 73.1% equipments were working while 21.2% were awaiting repair. The procedure of ‘maintenance request" was noted in log book for all equipments. 3 of the equipment were having the long down time period above 5 years. Non functional equipment with long down time period was due to non availability of the spare parts in 21.2% equipment and vendor was not responding for maintenance in 5.7% equipment Conclusion: There was need of proper equipment maintenance system in department. The long down time period of equipment was due to old technology, non-availability of parts and non-responding vendors.

RESUMEN
O objetivo deste estudo foi definir uma metodologia para a definição de intervalos de contratos de manutenção e recomendações gerais em um grande hospital da cidade do Rio de Janeiro, Brasil. A confiabilidade de 161 dispositivos de monitoramento e tratamento cardíaco foi estudada por meio de quatro indicadores de suas condições de uso. Esses indicadores, juntamente com o ano de fabricação do equipamento, foram usados como preditores em um modelo de regressão logística que teve como desfecho a ocorrência de falha no equipamento. A seguir, o Mean Time Between Failures (MTBF) foi estimado para os indicadores apontados como relevantes pelo modelo. Apenas uma variável (intensidade de uso) foi considerada estatisticamente significante no modelo preditivo final. O MTBF, de acordo com as categorias dessa variável (baixo-médio-alto), tiveram valores compreendidos entre 121,3 (baixo) e 5,8 (alto) dias. Os resultados indicam grandes inadequações nos períodos de contratos de manutenção utilizados pelo hospital e sugerem que estratégias de manutenção mais eficientes seriam períodos de inspeção compatíveis com os intervalos de MTBF identificados.
The objective of this study was to define a methodology to assist the definition of maintenance contract intervals and overall recommendations for a large hospital in the city of Rio de Janeiro, Brazil. The reliability of 161 cardiac monitoring and treatment devices was studied. Four indicators of equipment use conditions were developed, and, along with the year of manufacture of the equipment, were used as predictors in a logistic regression that had the occurrence of failure as outcome. The mean time between failures (MTBF) was then estimated for the categories of the indicators deemed relevant by the regression. Only one variable (intensity of use) was statistically significant in the final predictive model, and the MTBF, according to each category of this variable (low-average-high), ranged from 121.3 (low) to 5.8 days (high). The results indicated large inadequacies in the maintenance contract periods used by the hospital and suggested that a much better maintenance strategy would be the inspection periods compatible with the identified MTBF intervals.
