THE MEANING OF NEUTROPENIA AND HOMECARE NEEDS ACCORDING TO CAREGIVERS OF CHILDREN WITH CANCER

Este estudo objetivou compreender os significados atribuídos pelos cuidadores ao processo de cuidar de uma criança neutropênica, em domicílio, e conhecer as necessidades de orientações para o cuidado dessas crianças. É estudo descritivo, realizado no Instituto de Oncologia Pediátrica, com onze cuidadores, utilizando entrevista semiestruturada. Os dados foram organizados segundo a técnica de análise de conteúdo e interpretados à luz das Representações Sociais. Os resultados indicam mudanças no ambiente físico, nas pessoas e nas relações humanas, evidenciando fases de crise e de transição para a estabilidade. Os cuidados que geraram dúvidas foram: hipertermia, higiene corporal, do ambiente e dos alimentos, riscos do contato interpessoal e cuidados especiais. Conclui-se que há necessidade de preparo técnico e emocional dos cuidadores para o enfrentamento das dificuldades apontadas, incluindo as condições de agravamento.


INTRODUCTION
Among treatments provided to children with cancer, antineoplastic chemotherapy is one of the most important and promising ways to fight cancer (1- 2) .Chemotherapy drugs can cause pancytopenia in hematopoietic tissue, which is characterized by the reduction of red blood cells, leukocytes (especially neutrophils) and platelets, generated by the specific action of these drugs (3) .
Education and care are used to minimize the risk of complications related to neutropenia.This is a vulnerable condition, whether the child is hospitalized or receives care at home.It is the role and responsibility of nurses to plan and implement educative actions so as to maintain and recover the patients' health condition, aiming to integrate these children into society, working with different aspects of values and attitudes, such as: respect, hygiene, and care delivery at the bodily and emotional levels (1,4) .
In this perspective, the goal of this study was to understand how caregivers interpret the process of caring for a child with neutropenia and the peculiar needs they have, with a view to obtaining support for the future planning and practice of educative activities in nursing.

OBJECTIVES
To understand the meanings caregivers attribute to the process of caring for a child with neutropenia at home.
To know the needs caregivers present in relation to orientations for home care to a child with neutropenia.

THEORETICAL FRAMEWORK
Knowledge originated in Social Representation was used, especially related to the understanding that consensual realities use reified universes as raw material (5)   .Consensual reality includes intellectual activity of daily life, "common sense theories", that is, "a body of knowledge spontaneously produced by members of a group and based on tradition and consensus" (5) , which suffers continuous appropriations of images, concepts and language that science (in this reified universe) launches on the contemporary world by the various means of communication (radio, television, internet, magazines among others) (5-6)   .
T h i s p r o c e s s i s p e r m e a t e d b y t h e transference and transformation of knowledge that will be explicit in the elaboration of behavior, as well as in the form and content of communication among individuals (6) .The construction of symbolic meanings will be simultaneously a cognitive and an affective act.
In this study, caregivers of children with cancer and with neutropenia present their own meanings regarding the illness process, risks inherent to the diagnosis, the treatment and its consequences, constituted in the experience of this process and in environments shared in hospital facilities.
This way, we intended to unveil these

Study design
This is a descriptive quantitative and qualitative study.Qualitative analysis is justified because this research method permits incorporating meaning and intentionality as inherent to acts, social relationships and structures (7) .

Setting
The study was carried out in the Chemotherapy Outpatient clinic of the Pediatric Oncology Institute (IOP-GRAACC), which is a nonprofit institution, located in the city of São Paulo, SP, Brazil.

Subjects
This study was carried out with 11 caregivers of children with cancer, who met the following inclusion criteria: -being the main caregiver of a child with cancer receiving chemotherapy treatment; -being previously informed about the risks of postchemotherapy neutropenia; -having cared for a child at home after antineoplastic chemotherapy.

Data collection
Ethical aspects

Semi-structured questions
-describe what it is/was like to care for a child with neutropenia at home -which procedures generated the greatest doubts?
-which procedures you feel needed orientations?

Data analysis
Quantitative data are presented in absolute figures, percentages and averages.Content Analysis (8)   technique was used for the analysis of qualitative data, which originated three representational schemes that were analyzed through the Social Representations framework.

Characterization of the sample
Ten mothers and one father participated in the study, with ages varying from 23 to 40 years (average 32.4 years).Three caregivers had completed primary school, four completed secondary school and four did not report their educational level.
The age of children varied from two years and four months to 11 years (average 5.2 years old).
Of these, four had a diagnosis of acute lymphoblastic leukemia and the remainder varied diagnoses of cancer and myelodysplastic diseases.
In relation to general living conditions, all lived in masonry houses and the average number of rooms was 3.6.The number of residents varied from three to seven and the average was 3.9 residents per house, with ages varying from 2 to 64 years.

Results of semi-structured questions
Semi-structured questions supported the construction of representational figures presented in this section and aim to provide the reader with a written and diagrammatic message of content originated in the interviews.
Verbalization about the process of care delivery to a child with neutropenia at home revealed many expressions of feelings that originated in the changes in the house's organization and dynamics (Figure 1).In response to the question related to the procedures that generated the greatest doubts, questions related to the management of hyperthermia, food and environmental hygiene and prophylaxis of infections prevailed.

Her temperature, I was afraid she'd convulse (E3).
When I saw he had a temperature, everybody started to cry at home; so I left in a hurry to the hospital (... Other reports evidenced difficulties in the management of social and interpersonal activities, such as transportation and staying in public places, in addition to fear of performing specific care as showed by the following reports: The other day a little friend of hers, who was on the bus, had chickenpox (..

In the beginning, I'd think at the time of giving medication whether it was going to work, if I wouldn't mess it up (E9).
When she went back home (after the last hospitalization) she had to do inhalation every three, four hours (...) I was scared, it was difficult to do the exercises on the first and second days, but then I learned it too (E2).
When asked about which procedures they needed orientations, interviewees mentioned the following: hygiene followed by questions of affective/ emotional support so as to overcome problems, risks of fall and injuries, medication administration, as well as other procedures related to tube feeding, special diets and intravenous catheters.
In relation to diet preparation and restrictions, the new needs make caregivers adapt, seeking to meet the multiprofessional team's requests and satisfy the child's desires at the same time.Caregivers have better mastery and express more security about care related to house cleansing and food preparation, though these still remain a source of doubts.
Her fruits are left separated, then when I get home, I wash them with tap water and put them in sodium hypochlorite.I sterilize her bottles with hot water.Alcohol, there's alcohol everywhere at home, when in doubt, I put it even on clothes (E2).
Third, interpersonal contacts generate fear and uncertainty related to different activities, such as attending school, going to the movies and shopping mall.The need to use collective transportation was also mentioned as a factor generating insecurity, because it is not under the parents' control and presents a risk of acquiring transmissible diseases.
To start off, you leave here worried, you know?You have to get the bus, it's crowded (E3).
Finally, procedures that are peculiar to the treatment or to its complications and the management of its side effects were also mentioned.Data related to the question "which procedures you feel needed orientation?could be grouped under care focus (Figure 3).We present the following reports related to care with food, environmental and body hygiene.
In terms of hygiene, food, we have to keep an eye on everything that happens.They get very vulnerable, helpless and then we have to protect them the best we can (E7).
I guess that you have to care more for his hygiene because the lesser contact he has with bacteria the better.What I take most care with is hygiene of vegetables, I soak everything in a product, peel off the tomato skin (E1).
Procedures related to hygiene were emphasized by seven of the participants as care that needed to be oriented but were also the ones easier to perform because they are already part of their daily tasks.The domestic environment seems to be the only place where caregivers believe to have real control to diminish the risk of infection.Therefore, caregivers believe this is one of the main types of orientation they need.
As mentioned before, the child with cancer might demand care with different levels of complexity.
In this perspective, some participants seemed apprehensive to have to perform all procedures in their daily routine and perform them well.
So (in addition to hygiene) you have to prepare food with less salt, almost no salt so as not to raise blood pressure, take the medication, be careful not to fall, not to have hematomas, see the blood, platelets… So, we have to take care of everything (E9).

Pay attention, be very careful and comply with the medication schedule (E8).
Other contents caregivers appointed as needing orientation are related to physical and affective preparedness to cope with and adapt to emotional issues involved in the process of caring for a child with cancer, with increased risks at home due to the neutropenia.
When the child is weak, vulnerable, love is essential (...) be patient, very patient and a lot of willpower (E2).
The most important thing is the father and mother to be together, that'sn it.There're children who have only the mother or the father, but both have to be by his side (E5).

ANALYSIS AND DISCUSSION
Analyzing the profile of the respondents, we could verify that parents are young and have primary and secondary school, which is a fact to take into account when planning the implementation of educative actions.
With the exception of one interviewed mother, all the others reported they did not have paid jobs as from the moment their children became ill and exclusively dedicated themselves to the family.In terms of living conditions, all of them reported living in masonry houses, though some reports evidenced the risks of exposing children to unsafe material in the external part of the house (debris, recyclable materials).
As shown in Figure 1, the perception of caregivers about the process of caring for children with cancer in the situation of neutropenia is marked b y c h a n g e s t h a t o c c u r i n d i f f e r e n t s p h e r e s : environment, people and relationships.In the p e r s p e c t i v e o f t h e o r i e s t h a t e x p l a i n h u m a n reactions in situations that require the use of coping and adapting resources, generally accompanied by stress, these are in a process of transition, which is initiated at the moment the person perceives the crisis.This can be a response to an event seen as a threat, like in the case of neutropenia induced by chemotherapy (9) .
Transition is a dynamic and regular process, marked by relational and personal changes in the attempt to find new support resources (9)(10)(11) .For the family, transition is difficult and exhausting.There are moments of anguish, concern and stress, which require the family to reformulate its routine so as to take care of the child and adapt to a new routine that permits maintaining the family unit (10)(11) .
caregivers' universe of representations to the extent that it can show the rationale of behavior and action (linked to representational beliefs).It is important to highlight that the beliefs of caregivers are reflected in their actions because they believe in the knowledge they have.

Field
research was initiated after approval and authorization were obtained from the Research Ethics Committee at São Paulo Federal University.The guidelines specified by Resolution 196/96 from the National Health Council were followed, aiming to ensure the participants' rights.Subjects formally manifested consent by signing the free and informed consent term.Characterization of the sample We initially attempted to identify the individual and social context of the participants by analyzing patients' files and then directly approaching caregivers.Data were collected in October 2007 through a semi-structured questionnaire, tape recorded and fully transcribed afterwards.
