Abstract
Objectives:
To compare the effectiveness of locally adapted Institute of Child and
Mother Health (ICMH) protocol with the WHO protocol for the management
of severely malnourished children in Bangladesh.
Design: Quasi-experimental non-randomized
clinical trial.
Setting: Hospital based.
Participants: Severely malnourished children
(2-59 mo) with weight for height <70% (n=60).
Intervention: Children treated with either WHO
protocol (Group I, n=30) or ICMH protocol (Group II, n=30).
Outcome variables: Clinical improvement, weight
gain, time taken to achieve target weight gain, and mortality among the
study subjects.
Results: Mean (SD) weight related to gain in
Group I and Group II was 11.2 (4.1) and 11.1 (3.9) g/kg/day,
respectively. The weight gain was not related to the age group or type
of malnutrition. The time taken for edema to subside (7.3 d vs 8 d) and
for improvement of appetite (6.5 d to 7.3 d vs 6.7 d to 8.4 d) was
similar between the groups. The target weight gain was achieved in 28.3
(11.5) days in Group I against 27.9 (6.2) days in Group II (P=0.88).
The mortality rate was 6.7% in each group.
Conclusion: Treatment of severe malnutrition with
locally adapted ICMH protocol using locally available foods is as
efficacious as the WHO protocol.
Key words: Bangladesh, Child, Malnutrition, Management

Severely malnourished
children have a high mortality rate. Even in the 1990s, mortality rates as
high as 49% have been reported for malnourished children in hospitals(1).
Optimum management of these acutely ill children and a good outcome
depends on an evidence based prescriptive regimen of care(2). High
case fatality rate in hospitals has been attributed to faulty case
management due to lack of knowledgeable staff and absence of prescriptive
guidelines. To address this issue, WHO has advocated a protocol and
various agencies have adapted it according to their need and available
facilities. In Bangladesh, Institute of Child and Mother Health (ICMH) has
been following its own protocol for the management of severe malnutrition.
A study conducted by Talukder, et al.(3) using ICMH protocol
showed a mortality rate of 4.5% among severely malnourished children.
The WHO protocol for the management of severe
malnutrition has some limitations. In this protocol, there are phases of
feeding from low to high calorie density. Treatment includes dose of a
combined mineral and vitamin mix (CMV), which is difficult to procure
locally. Whereas, ICMH protocol is locally adapted and easy to follow. The
calorie density is same through-out and micronutrient deficiency is
corrected using locally available minerals and vitamins.
This study was conducted to compare the outcome of
management of severe malnutrition in children by ICMH protocol with the
WHO protocol. Our study was based on the hypothesis that a similar outcome
can be achieved by modifying the WHO protocol, by providing fixed calorie
diet and replacing CMV with locally available vitamins and minerals.
Methods
This quasi-experimental clinical trial was conducted in
two hospitals for six months from June to December 2003. One hospital each
used the WHO protocol and ICMH protocol for treating severely malnourished
children(4,5). The sample size for equivalence was calculated assuming
that the mean time taken for targeted weight gain is 25 days in each group
with SD of 6 days. Minimum acceptable difference in the two groups was 4.5
days with alpha error 0.05, and power 80%.
Severely malnourished children, aged 2 months to 59
months, whose weight for height was below 70% of the expected (NCHS/WHO
references)(6), with or without bilateral pitting edema were included in
the study. Children with major congenital abnormalities or disabilities
and having feeding difficulty were excluded. All children belonged to the
urban and periurban areas of Dhaka. Children at Ad-din Hospital, Dhaka
(Group I, n=30) were managed according to WHO Protocol(4). Children
at ICMH, Dhaka (Group II, n=30) were managed by ICMH Protocol(5).
Senior staff nurses and doctors of each hospital were trained on the
specific management protocol. Senior staff nurses were involved for
supervised feeding and monitoring of children, and in helping the
physician during anthropometric measurements. Study children were assessed
by history, anthropometry, clinical examination and laboratory
investigations and managed as per specified protocols. Permission from the
ethical committee was obtained and, an informed consent was obtained from
the child’s guardian before including the child in the study.
Management
Group I: WHO protocol: The management of children
with severe malnutrition was divided into 2 phases; initial, and
rehabilitation phase and managed as per the protocol(4).
Group II: ICMH protocol(6): In this
protocol, there was no phasing in the management. Identification of
life-threatening problems, and management of unconsciousness, convulsion,
hypothermia, and hypoglycaemia were done as for Group I. Correction of
electrolyte imbalance and micronutrients deficiencies were done by giving
locally available minerals and trace elements like Potassium chloride (5
mmol/kg/day), Magnesium sulphate (10 mg/kg/day), Zinc sulphate (2
mg/kg/day), Folic acid (2.5 mg/day), and multivitamins 0.6 mL/day
(com-position per 0.6 mL of multivitamin: vitamin D1, 200 i.u., thiamine 1
mg, riboflavin 1 mg, pyridoxine 1mg, panthenol 2mg, nicotinamide 5mg,
vitamin C 60 mg) orally. Copper was not available in the local market for
use. Iron supplementation (6 mg/kg/day) was started on the 15th day. In
case of severe anemia with or without heart failure, blood transfusion was
given. Every child was given vitamin A supplement. Antibiotics used in
this protocol were the same as recommended by WHO. Feeds were made using
whole cow’s milk, sugar, soya oil and water to provide 100 kcal in 100
mL/kg/day administered every 2 hours during day and night. If the child
wanted more than the prescribed diet, extra family food was given
ad-libitum and breastfeeding was encouraged. Play therapy, nutrition
education, and discharge criteria were similar to those for children in
Group I.
Outcome measures
(a) Clinical: improved appetite,
disappearance of edema, improvement of other associated medical
conditions.
(b) Catch-up growth: weight gain in
gram per kg per day.
(c) Time taken for gaining target weight
(weight for height reaching 1SD (90%) of NCHS/WHO median reference
values) calculated from admission weight using NCHS/WHO reference growth
chart.
(d) Mortality rate.
Statistical analysis: All the clinical parameters,
appetite, weight, edema etc. were collected daily. Data were collected
through structured questionnaire and checked manually at collection period
and prior to entry into computer program. MS Access was used for data
entry and SPSS/PC+ for analysis. For comparing the continuous variables
like mean weight gain, mean duration of gaining target weight among two
groups, student’s t test was used, and for comparing the mortality
rate, chi- square test was used.
Results
The baseline characteristics of the two groups were
similar (Table I). Two third children were marasmic and one
third had edematous malnutrition. Table II compares
outcome variables between the two groups, which were found to be
comparable.

Discussion
For the management of severe malnutrition in the
hospital setting using the WHO protocol, the gradation of hypo-to
isocaloric feeds and the use of specific vitamin mineral mix may not be
feasible, especially in developing countries. For the manage-ment of
malnourished children, the protocol developed by ICMH differs from that of
WHO. In the ICMH protocol; (i) the child was fed with fixed caloric
diet, 100 Kcal/kg per day from the beginning of management and continued
throughout hospitali-zation; (ii) vitamins and minerals were not
mixed with the diet; and (iii) potassium, zinc, magnesium and
multivitamins were given separately. The present study result has shown
that local adaptation of the protocol can yield comparable result.
The study is unique in the sense that it has documented
comparisons of treatment outcome in terms of specific indicators like time
needed for gaining target weight, weight gain in grams per kg per day and
mortality. Though the sample size seems small, the power calculation is
enough for the time to achieve target weight gain. For mortality, this
sample size may not be adequate. Again the study groups were not taken
from same hospital. This could lead to some selection bias.
Time to reach target weight in our study (28.3 days and
27.9 days in two groups) is similar to that reported earlier(7). Two
children in each group expired within 48 hours of hospitalization. These
children had hypoglycemia, septicemia, severe dehydration, heart failure
and shock. The mortality was 6.7% in both the protocols, which indicates
moderate case fatality(4). Similar mortality rate was also observed by
Kabir, et al.(8). One third (33.3%) of children in each protocol
had edematous malnutrition. It took 7.3 (2.7) days in WHO protocol and 8
(1.8) days in ICMH protocol for edema to subside. The edema of most of the
children began to subside on the 4 th
day of initial management similar to that observed with WHO protocol(4).
The average duration of improvement of appetite of most of the children
was 7.6 days and it was higher than that observed with WHO protocol. The
weight gain of the recovered children showed similar result in both
groups. The rate of weight gain in marasmic kwashiorkor children was
higher than that in marasmus and kwashiorkor in both the protocols.
Catch-up growth rate in 0-6 month old children was slightly higher in ICMH
protocol group than that in WHO protocol group (17.5 vs 11.6 gram/kg/day),
though this difference was not statistically significant (P=0.21).
Catch-up growth rate was almost same in sub groups with or without pedal
edema in both the protocols.
If the feasibility of implementation of local protocols
is considered, there was no change of diet from F-75 to F-100 in ICMH
protocol; rather, same calorie-dense food (100 kcal/100mL) was provided
throughout the whole length of stay in hospital. Locally available cow’s
milk, zinc, potassium, magnesium sulphate and multivitamins were used in
ICMH protocol instead of imported skimmed milk and CMV. Standard ORS was
used instead of CMV based ReSoMal to correct dehydration. Though
acceptance was not specifically studied, the service providers appreciated
the simplicity of ICMH protocol. Although the cost involved in managing
severely malnourished children was not calculated methodically, it is
presumed that because ICMH protocol depended on locally available products
and duration of hospital stay was almost same, the cost would be lower in
case of ICMH protocol.
The result obtained in this study has important
implications in introducing protocol based manage-ment of severely
malnourished children in hospitals with limited resources. ICMH protocol
appears to be a feasible alternative in district hospitals of developing
countries for management of severe malnutrition.
