relevant in the context of nursing practices since, when
assisting cancer patients within their basic human needs,
food should be prioritized to contribute to treatment.38,44
The IQNT “NT prescribed versus infused volume” reflects
the evolution and quality of nutritional care, and for the
oncological patient to be able to receive the prescribed
volume of EN, several factors are fundamental, such as the
suitable dietary prescription, the appropriate route of
administration of EN, the quality of the EN device, the
monitoring and control of complications.13. Given this,
research32,33,35 reveals the engagement and protagonism of
Nursing in EN area, with promising results regarding good
practices in the administration of EN (GPAEN). 45 In a
study developed in Israel,46 nurses conducted a protocol to
address and correct the deficiencies of EN in an ICU, and
the feeding of the patient was started significantly earlier
(p = 0.007) in the intervention group (52.3 hours; SD, 42.6)
than in the control group (70.3 hours; SD, 65.2). The use
of the protocol resulted in a significant increase in
nutritional intake in 90% in the intervention group.
Studies that did not reach the IQNT goal21-26,29 identified
that the investigated hospital units were clinical and/or
surgical,22,24,26 adult/general ICU,21,25,29 and medical clinic,
29 and only three of these institutions22,26,29 owned MNTT.
Hospitals that reached the indicator’s goal were
general/adult ICU,27,28 Cardiologic ICU,27 and palliative
care unit.23. In these scenarios, the oncological patient is
already in a state of metabolic stress that triggers numerous
nourishing supplements deficits, which result in increased
nutritional needs.1,2 Thus, the research analyzed that, even
in closed/controlled hospital units, such as the ICU, and
the fact that the hospital institution has MNTTs, the
effectiveness of ENT for adult cancer patients is not
guaranteed, which minimally generates a movement to
(re)think nursing practices in ENT in these care units.
Therefore, especially in specific populations, the goal of the
IQNT “NT prescribed versus infused volume” can be
presented above what the cancer patient can receive, and
the patient’s clinical conditions should be evaluated for the
measurement of the indicator goal.
Regarding the length of application of the EN and the
IQNT, the research found that in studies that did not reach
the goal, oncological patients used the EN, on average, for
more than five days,22,24,26,29 corroborating with a study 47
in an oncology hospital, which identified that none of the
patients (n=96) managed to reach the prescribed volume of
EN, on seven days of exclusive EN. Indicator goals for
these studies alternate between ≥ 70%,24-26 ≥80%,21,26 and
≥ 90%,22 indicating that sometimes Brazilian institutions
follow the ILSI Brazil guidelines,13 sometimes they stipulate
their own targets according to the characteristics of the
hospital unit. For institutions that adopt different goals
(higher) than recommended in the guideline,13 planned care
structure, good health practices, and implementation of
protocols are necessary.13 Thus, one of the fundamental
elements for good results is to have MNTTs, which
perform the appropriate nutritional assessment36, choosing
the adequate device,48 the early onset of EN,39 monitoring
for complications of EN,34 the application of IQNT,49 and
continuing education actions.35,43,50
Among those studies that were able to achieve the goal, the
length of application of EN in cancer patients was greater
than five days,23,27,28 evidencing the existence of a
proportional relationship between time and the ability to
achieve the adequacy of the prescribed volume.47 This
situation can be explained because, in the first days of
hospitalization, cancer patients tend to present an unstable
clinical picture, greater exposure to health procedures and
interventions, and a care plan still in definition and
adaptation.48 Therefore, establishing the number of days
for EN requires more time for its administration. The goals
adopted by these institutions ranged from ≥70%27,28 and ≥
80%,26 following the guidelines of ILSI-Brazil and its
reformulations.13
The clinical repercussion in cancer patients who receive a
lower volume of EN is raised in different studies, 3-6 which
demonstrate that not reaching the goal of EN is correlated
with worse clinical outcomes, such as infection 4 issues and
complications3,5,6 during hospital stay. In this sense, there
must be a reflection to try to minimize the discrepancy
between nutritional planning and the effectiveness of this
plan. For nursing, it is necessary to ensure that the
prescribed volume is adequately infused, and, for this, it is
required to train the nursing team regarding the skills and
competencies that subsidize qualified care with EN and
patient safety.51
One of the reasons why the prescribed volume of EN is
not entirely infused in the adult oncological patient is
associated with gastrointestinal, metabolic, mechanical, and
respiratory character complications. Both in the studies that
reached and in those that did not reach the goal of the
indicator, the reasons for the major complications of EN
were gastrointestinal.21-23,25-29 Therefore, the analysis
observed that the main element that makes the cancer
patient unable to reach the prescribed volume of ENT is
linked to its clinical fragility that triggers gastrointestinal
complications, directly affecting the volume that the patient
should receive. That is, the clinical difficulties of the cancer
patient directly affect the volume of infused EN, and not
only the IQNT processes themselves.
For more than a decade, nurses have been conducting
research on different patient profiles39-40,50-51 to monitor
complications on the use of EN. In a prospective cohort,52
157 ICU patients were followed daily during the first ten
days of hospitalization and, among those who received and
did not receive EN, complications such as diarrhea and the
need for gastric decompression were more frequent in the
EN group (39.7 % vs. 11.7 %, p < 0.001 and 34
% vs. 13.3%, p = 0.004, respectively). Therefore, it is
necessary to constantly reevaluate EN care practices, from
the evaluation of diet formulation, the characteristics of EN
administration, the correct positioning of the tube, and the
continuous infusion mode.53
