INTRODUCTION
The Material Storage Center (MSC) stands out in the context of health organizations in a rather peculiar way, as it supports all care and diagnostic services that need dental-medicalhospital products for care delivery to their users. 1ne of the factors that decisively contributed to the implementation and consolidation of MSCs in hospitals was health teams' awareness about the need to control hospital infections, which directly affect the quality of care delivery and often entail extended hospitalizations and, hence, increased hospital care costs.] The MSC comes with a distinguished work process and specific activity area for nurses who, using a range of scientific and technological knowledge to coordinate the work, seek integration with consumer units and support units at the hospital institution, characterizing a relation of interdependence.
] Concerning the functions at this unit, the competences required from nurses are related to the management of the sector, technical-care activities and human capital management, demanding a set of structured knowledge that permits the achievement of their proposed work goals at a unit with such great accountability.
In that perspective, another challenge MSC nurses are confronted with is related to the work process itself at the unit, strongly marked by invisible action, considering that indirect care is less value, although this practice is based on tacit and scientific knowledge that could enhance social acknowledgement. 6he characteristics of MSC work are very distinct from other hospital units.Despite legal regulations on adequate MSC structures, in practice, it had been verified that they do not correspond to the current panorama, in which the functional requisites are not attended to, in terms of neither physical structure nor activities performed.As a result of that panorama, a range of services is available, which consequently affect the set of activities the professionals working at the unit perform.
In the literature, various documents have been published, offering legal solutions that indicate not only the MSCs' functional scope, but also the activities the nursing team is supposed to develop.This description is based on the finding that, traditionally, nursing is in charge of management at this unit, given its accountability for the organization of the therapeutic space in he hospital.
Hence, concerning the execution of the MSC nursing professionals' activities, the Federal Nursing Council (COFEn) defined and determines, in its Decree 94406/1987, which regulates Law 7.498/86, that the task of auxiliary nurses includes cleaning activities, putting material and equipment in order, as well as disinfection and sterilization, under nursing supervision and orientation. 7hen, Collegiate Board Resolution 307/2002 was published, which endorses the aspects inherent in the establishment of this unit's own activities, 8 without addressing various technical-administrative activities though, such as planning, organization, coordination, orientation, supervision, training and continuing education, activities and responsibilities that are part of nurses' daily work in MSC. 9 In the same sense, with a view to strengthening the legal standards elaborated to support nurses working at MSCs, in 2007, the Brazilian Society of Surgical, Anesthetic Recovery and Material Storage Center Nurses (SOBECC) published an extensive list of activities established for the nursing team at that unit. 10onsidering the complexity of the work process at that unit and of events involving the quality of processes related to the reprocessing of different medical-hospital material, recently, RDC 15.2012 was published to set the best practices for the functioning of health product processing services and, among these, the responsibilities of the nursing team are described. 11n view of that document, COFEn publishes Resolution 424/2012, in view of the need to regulate the responsibilities of nursing team members working at Material Storage Centers in Brazil.That resolution has been considered a guideline for professional nursing practice at that unit. 12mong the publications that establish and recommend a task profile, a study should be mentioned that was developed at hospitals in São Paulo City, which are considered referral institu-tions and performance benchmarks for the work processes accomplished there, in which the nursing team activities at MSCs were identified and validated.That research permitted the elaboration of a flowchart representing the actions undertaken at the unit, including six areas, 25 work subgroups and 110 activities, besides 25 nursing activities. 3iven the particularity of the institutions where this research was undertaken, the investigation of different hospital realities in Brazil was considered relevant, especially concerning the work of MSC nurses, with a view to gaining a more comprehensive view of work at these units and understanding the complexity and peculiarity of this professional's activities, as well as to reassert their importance in the management of that service.
In view of these considerations and the relevance of the theme for professional nursing practice, this research was undertaken to identify nurses' activities in MSCs of hospital institutions according to the activity profile and the frequency of their accomplishment.

METHOD
A descriptive and cross-sectional study was undertaken.The population consists of clinical nurses and/or nurse faculty in Material Storage Centers of public, private or non-profit hospitals in Brazil, who possess professional experience and expertise in the research area.To select the subjects, the snowball technique was chosen, 13 considering the importance of experience or expertise on the subject to achieve a consensus on specialized ideas.
The recruitment started with the signaling of an initial key informant, who was the Coordinator of the Perioperative Nursing Area at the University of São Paulo at Ribeirão Preto College of Nursing, an acknowledged academic institution in Brazil and internationally.That person was asked to indicate the name, function and e-mail address of three professionals who might comply with the sample composition criteria.
After identifying the probable participants, the research was presented by e-mail, through a document that presented the project to the identified professionals and invited them to participate.
An exclusive e-mail address was created for this purpose.If they agreed to participate, the Informed Consent Term was sent, followed by the questionnaires.
For data collection, two self-applied instruments were elaborated, one to characterize the participants, and the other called "Questionnaire about specific nursing activities at the MSC", including 25 specific nursing tasks at this service, constructed based on the study developed in a Master's thesis. 3The participants were expected to assess and score the frequency of the activity described on a Likert scale, ranging from never to rarely, daily, weekly and monthly.One alternative should be marked for each instrument question, and completion was essential to move on to subsequent pages and access the complete questionnaire.Besides the list of activities, space was provided to add any activities not addressed in the list, according to the respondent's opinion.
To collect the research information, advice was sought from an informatics expert, who indicated the tool Google Docs Off line®, which was considered highly versatile and permits different uses, including a simple questionnaire, registration form, opinion poll, survey, etc.In addition, it can easily be shared by e-mail or through a direct link, making this tool a very interesting option for teachers, students, researchers and professionals whose work involves the application of questionnaires. 14he collected answers are automatically included in a worksheet, making it easy to produce statistics.
The entire document flow in this research was done by e-mail, and the researcher had exclusive access to the results.A 15-day deadline was set for the participants to return the questionnaires and data were collected between July 2011 and April 2012.
For the sake of data analysis, descriptive statistics were applied to the study variables, using frequency distribution, and the results were grouped in tables.
In compliance with National Health Council Resolution 196/96, approval for the project was obtained from the Research Ethics Commission at the University of São Paulo at Ribeirão Preto College of Nursing (Protocol 1331/2011).

RESULTS AND DISCUSSION
Eighty-two professionals were contacted and agreed to participate.They received the link to the data collection instrument by e-mail and 31 professionals responded, who constituted the research sample.
The choice of the electronic tool was based on a literature review, in which studies were identified that indicate the use of technological tools for studies that use the web as an ally in the research process.When well used, these auxiliary and support resources make it easier for the investigator to accomplish the research. 15nline research can meet with greater resistance to answer the study, as many users are fearful that their data might be used improperly or for criminal purposes, and therefore prefer avoiding access to unknown websites that may weaken their personal security. 16ur study supports the assertion that, despite the enhanced development of communication methods and technologies that permit faster and more precise contact with the population of interest for the research, resistance was faced to participate in the online research.
As regards the participating nurses' characteristics, table 1 displays the variables collected.The data demonstrate that, among the nurse experts in MSC, 93.55% are female, between 21 and 60 years of age, with 35.49% between 21 and 30 years old.As regards the graduation time, 61.29% graduated less than 15 years early, but mostly between one and five years.Concerning professional experience in the area, 58.08% have between one and five years of experience in the sector.
Brazilian literature reveals few studies that describe the profile of nurses working at MSC services.In a study of 18 health institutions in Curitiba-PR, aimed at describing nurses' perception about the elements of their work process at the MSC, 93.3% of the subjects were female, between 41 and 50 years of age (53.3%), up to five years since graduation (53.8%) and between two and five years of experience at MSC (60%). 17xcept for the age range, graduation and experience characteristics are similar, showing the profile of professionals working at this specialized service.
The data regarding complementary education indicate that 33.35% of the participants hold a specific specialization degree in MSC.Studies have shown that professional education should contribute to the renewal of the administrative dynamics of nursing services, valuing the specific knowledge of MSC nurses and the importance of this sector for the quality of care delivery. 18s regards the professionals' activities, focused on in this research, the data are described in table 2, together with the respective frequency of their accomplishment.
The analysis of the answers indicates that most of the respondents marked 15 of the activities listed as daily and nine as monthly.Among the activities indicated as daily and accomplished most frequently, the following stand out in decreasing order: supervision of activities at the unit; confirmation of surgery program, checking availability of sterile materials and garment; attendance to consumer units; coordination of work process at the unit; team monitoring in execution of activities, mainly new professionals; supervision of functioning of equipment used in each work area; confirmation of surgery program, checking delivery of consigned materials; and verification of sterilization control documents.Management is the main nursing activity at the MSC, comprising different functions, such as planning, elaboration of administrative and operational instruments, material and human resource management and supervision.Nurses' activities are concentrated on material and staff organization, with processed or reprocessed medical-hospital products as their work object. 19The instruments of these professionals' work process are knowledge, communication and interpersonal relations and planning.
These data are similar to a study of ten MSC nurses in Campinas-SP, which showed management as the main activity of nurses at this unit, including different functions, such as planning, elaboration of administrative and operations instruments, material and human resource management and supervision.In this study, the man-Gil RF, Camelo SH, Laus AM agement activities all participating nurses most indicated were material resource management, mainly prediction and provision, control and verification of preparation. 20n the hospital area, material resource management has stood out, mainly as a result of technological advances in recent decades.The incorporation of sophisticated technology is illustrated by the increased complexity of care practices and the challenges public and private managers face in view of the enhanced supply of products, and permits the monitoring of product quality, guaranteeing safety for patients and health teams. 21he Material Storage Center is a service that articulates with practically all hospital sectors, as it provides medical products to so-called consumer units, including not only the Surgical Center, but also hospitalization units, the outpatient clinic, the emergency unit, among others. 22he nursing staff has detailed knowledge about care and service dynamics, and is generally responsible for managing materials and health services at the sector.This clearly shows the relevance of material resource management for nursing work. 23nitially, the MSC was responsible for processing, storing and distributing dentalmedical-hospital products and equipment, using different work instruments (equipment, material, techniques, standards, communication, scientific knowledge, in-service education, management, etc.).Nowadays, however, the service goes beyond and is aimed at delivering indirect care through the availability of safe products that support direct care delivery by other sectors (consumer units) in response to the clients' health needs. 4SC nurses need to demonstrate their competences with regard to the modernization of the production process, and mainly the valuation and constant recycling of human resources, through effective continuing education that is committed to the development of nursing professionals' full range of potential, in response to the new technologies that are put in practice. 18ne aspect that demands careful analysis refers to activities related to the nurses' supervision of the functioning of equipment used in each work area.For this purpose, they need to know their equipment and their proper functioning, so as to guarantee the reliability and safety of client care.Monitoring the equipment and training the employees responsible for operating the machines is fundamental for the service to perform well.
Concerning medical-hospital material, MSC nurses' responsibility to verify the surgical program of the consigned material during its reception, usage control, charge and return of this material represents a daily task, but not for all respondents.At some institutions, this responsibility does not exist for these professionals, indicating a different structure of the MSC work process, predominantly with regard to surgical material.
Another surprising aspect relates to the nurses' lack of participation in research (41.94%).This is a rare activity for 48.39% of the respondents.Only 9.67% of the nurses report monthly research activities.According to existing studies, this production takes the form of master's thesis, doctoral dissertation, specialization and scientific initiation monographs, as well as books and presentations at scientific events. 20at the MSC nurses' professional practice is concerned, one may say that the primary function of this service is to offer support for patient care delivery in different situations.The predominant activity in this specific work is the management of different medical-hospital products' processing.
Nevertheless, the increasing supply of disposable medical-hospital material and the outsourcing of services have made several MSC activities obsolete. 20In addition, products have evolved and items originally manufactured for single use are being reused, incorporating new questions about the future of MSC work, which will certainly determine a new format for its structure and activities.

CONCLUSIONS
The study revealed the profile of nursing professionals working at MSC and permitted the evaluation of how frequently the activities these professionals are responsible for at this specialized service are accomplished.The MSC is characterized as a sector in health institutions whose work process comprises specific knowledge and practices, with distinctive objectives and goals when compared to other units.Due to its characteristics, its work is acknowledged as indirect care, equip-Nursing tasks in the material storage center of hospital… ping health care and offering the support needed for different care activities.
Among the 25 activities listed in the data collection instrument, which refer to validated activities that picture the work of nurses at MSCs, 15 activities are accomplished daily, nine monthly, 14 are not frequently accomplished and some never.
The research permitted the identification of research needs in the area of MSC, deepening nursing management knowledge and suggesting further research to assess the different facets of nurses and nursing teams' work.
