ABSTRACT
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.
ABSTRACT
Background & objective: Japanese encephalitis (JE) outbreaks are common in Assam, northeastern State of India. Information on resistance in known JE vectors in the affected area is important for effective control measures. This study was undertaken to determine the species abundance of JE vectors endemic to Sibsagar district of Assam, and their susceptibility against DDT and deltamethrin. Methods: Adult mosquitoes were collected using CDC light trap and aspirators from human dwellings from 13 endemic villages falling under three Primary Health Centres. Collected mosquitoes were identified and unfed female mosquitoes were used for DDT and deltamethrin sensitivity bioassay. The bioassay was performed following WHO protocol using standard susceptibility test kit. Knockdown time (KDT) was monitored at every 10 minutes intervals, whereas mortalities were recorded 24 h post-exposure. Vector density and resistance status were mapped using geographic information system (GIS) technique. Results: A total of 7655 mosquitoes were sampled under three genera, i.e. Anopheles, Culex and Mansonia, and nine species, the JE vector Cx. vishnui group (31.78%) was the most predominant species, followed by Ma. uniformis (16.81%) and Ma. indiana (16.45%). All vector species were suspected to be resistant to DDT and sensitive to deltamethrin, except Ma. indiana, which was suspected to deltamethrin resistant. The KDT50 and KDT95 values of vector mosquitoes for DDT were significantly higher as compared to deltamethrin. The probit model used to estimate KDT50 and KDT95 values did not display normal distribution of percentage knockdown with time for all the vectors tested for DDT and deltamethrin, except for Ma. indiana for deltamethrin assay and Cx. gelidus for the DDT assay. Interpretation & conclusion: Differences in insecticide resistance status were observed between insecticides and vector species. The results of this study provided baseline data on insecticide resistance in known JE vectors of Sibsagar, Assam. The maps generated may allow better communication in control operations and comparison of changes in susceptibility status of these vectors over time.
