Objective: This study aims at assessing survival status and its associated factors among under-five children admitted with complicated severe acute malnutrition to stabilization centers of Hospitals in Wolaita Zone.
Method: A retrospective cohort study comprised of 340 under-five children admitted for treatment of complicated severe acute malnutrition in two hospitals of Wolaita Zone in past 39 months. From the study period, the data were collected using the structured checklist, then entered and cleaned by Epi info version 3. 5. 4 and analyzed by SPSS version 20. Descriptive statistics was used to summarize child characteristics and treatment outcomes; cure rate, death rate, defaulters, and non-responders. Variables that were having P-value < 0.25 in bivariate analysis were entered into a multivariable Cox- proportional regression model to identify the predictors of mortality. Level of statistical significance was declared at p-value < 0.05.
Results: From a total of 30 deaths occurred at SC 13, 8, and 6 deaths occur within 72 hours, 4-6 days and 7-9 days after admission respectively. The majority of death 63.3 % occurred in children age < 12 months and the same magnitude 10 % for 13-24 and 23-36 months of age groups. Being septic at admission with their respective 95 % confidence interval were 2.9(1.03, 8.40), being hypothermic 11.8(3.77, 37.02) and not giving antibiotics at admission 3.7(1.55, 8.64) were an independent predictors of death.
Conclusion: Preventing hypothermia, treating sepsis and providing antibiotics at admission has a major effect in saving the life of children with complicated severe acute malnutrition in the stabilization centers. Thus, special attention should be gven for children with hypothermia, sepsis and provision of antibiotics for further reduction of death within the first few days of admission is faramaunt important. Keywords: Complicated Severe Acute Malnutrition; Mortality Rate;
Ethiopia is one of the countries with highest under-five child mortality rate, with malnutrition underlying to 57% of all children’s deaths [7]. The urban-rural difference in mortality rates is more pronounced in the case of under-five year aged children. Under-five mortality rates range from a low of 53 per 1,000 live births in Addis Ababa to a high of 169 per 1,000 live births in Benishangul-Gumuz. Under-five mortality is also relatively high in Afar, Gambella and Somalia [8]. Likewise, in southwest and south Ethiopia, studies revealed that the recovery rate and defaulter rate were remote from the international acceptable standard ranges [9]. Despite the existence of inpatient and other nutrition programs in every corner of Ethiopia, the national survey and different studies, have shown that deaths due to severe acute malnutrition are indicated to be still high [8,10].
Recently, research conducted in Jimma and Eastern Ethiopia has shown that the death rate was 9.3% (27.3% in the first 48 hours and 60.2% by the end of the first week) and 13% respectively [11,12]. The first week of inpatient stay was the most critical to the survival of children; most deaths occurred during this period [11,13]. Having co-morbidities prior to the admission, development of cross infection during the stay, being critical at arrival, lack of regular and supportive supervision, lack of training for TFU staffs regarding the guideline for the management of SAM and high staff workload during the night affects the treatment outcome. These are the potential contributors that lead to inappropriate management and increased death rate [14]. The dissimilarities of mortality and survival status in different study settings may be related to variation in quality of service delivery.
Even though enormous problems determine survival status, limited studies were done in the country and no evidence found mainly in the study settings. Therefore, the study intended to assess the survival status and it associated factors among under-five children admitted with complicated SAM to SC is public health important problem in Ethiopia especially in the study settings with limited resources; the burden is more than anticipated.
Regarding study settings WSUTRH from a total of 255 functional beds, of them 70 beds are reserved for pediatric age groups. Total inpatient admission in the last year is 8,762 and the bed occupancy rate was 74.5%. Meanwhile, the disease burden SAM is the 8th top cause of under-five year admission [16]. Similarly, in Dubbo St. Marry Primary Hospital had 103 functional beds of them 33 were reserved for pediatric age groups [17].
Exclusion criteria: Incomplete records of c children’s chart with incomplete data of age and/or sex. Children whose treatment outcome not recorded and children whose admission date and discharge date not recorded.
Event: death; Times to the event: time to death from admission till death happen.
Independent variables
Child characteristics: age, sex
Residence: Urban and Rural
Clinical conditions: vomiting, dehydration, edema
Co-morbidities: the presence of one or more additional disease or co-occurrence with primary disease.
Treatment Outcome: weight gain, defaulter, non-responded, absconded, death, cure
Medication: routine antibiotic (amoxicillin, Vit. A, folic acid, deworming, anti-malaria, ReSoMal) and special medication (IV fluid, IV antibiotic, blood transfusion)
The checklist consists of the following information: Patient related data (age, sex, and residence), Co-morbidities/infection, types of severe acute malnutrition, feeding phase and types of feeding, frequency of feed and amount per feed, medication given, and health information on different topics, Condition at discharge and date and time of death.
To avoid repetition of reviewing a single card attached with its checklist until the principal investigator verify the completeness and put a unique mark to prevent recurring review and kept it in separately until the compilation of the data collection period. Charts with more than one round admission were reviewed only for latest readmission and for it only because one chart reviewed only once. Data was extracted first from children’s registers and then from records (card and multi-chart). Collected data were sorted and checked for errors and completeness on site daily by supervisors. Finally, data from two sources was linked by patient’s card number.
Complete record: if age in months, sex of the child, admission date and time, type major complications, discharged date and treatment outcome recorded.
Complicated SAM: Children who are acutely malnourished with associated medical complications and/or poor appetite; and infants less than 6 months with SAM
Co-morbidities: In children with severe acute malnutrition, having TB, and/or HIV and/or malaria and/or pneumonia, and/or diarrhea, and/or severe anemia co-infection on admission to stabilization center.
Cured: Patient that has reached the discharge criteria with improvement
Dead: Patient that has died whiles he/ she was in the programme stabilization center.
Defaulter: Patient that is absent for 2 consecutive weighing (2 days in inpatient).
Hyperthermia: Defined when the body axillary temperature is ≥38.5°C [18].
Hypothermia: Defined when the body axillary temperature is below 35°C [18].
Inpatient Treatment/ care: Children who are acutely malnourished with associated medical complications and/or poor appetite; and infants less than 6 months with the SAM need to be treated in an inpatient care facility until they are well enough to continue nutritional rehabilitation in OTP.
Non-responder: Patient that has not reached the discharge criteria after 40 days in the inpatient program [18,19].
Phase 1 (Stabilization phase): children with complicated SAM are initially admitted to an inpatient facility for stabilization. In this phase: Life-threatening medical complications are treated, Routine drugs are given to correct specific deficiencies, Feeding with F-75 milk (low caloric and sodium) is begun [18].
Sepsis: The presence of bacteria (bacteremia), other infectious organisms, or toxins created by infectious organisms in the bloodstream to spread throughout the body [20].
Severe Anemia: If the hemoglobin concentration is less than 40g/l or the packed–cell volume is less than 12% the child has very severe anemia.
Phase 2 (Rehabilitation Phase): Children that progress through phase 1 and transition phase enter phase 2 (rehabilitation phase) when they have a good appetite and no major medical complication. In this phase: Routine drugs are continued, Feeding with RUTF or F100 is started [18].
Survival: those who are alive at discharge from stabilization centers.
Time to event: Death is the event of interest. Time to event was calculated in days by subtracting the date of admission from the date of event occurred in under-five children admitted with severe acute malnutrition to stabilization centers of study settings during the study period.
Transition phase: Once the child appetite recovers and the main medical complications are under control and edema start to reduce, a transition phase is started where F-100 or RUTF (Ready-to-Use Therapeutic Food) is introduced [18].
Under-five children: age of 0-59 months
Multivariable Cox regression was preceded by bivariate Cox regression during modeling. Variables with p < 0.25 by bi-variable analysis and missing information either (present/absent) of specific variables not more than 5% were considered as candidate for multivariate cox-regression. Multivariable Cox regression was run using the Forward Wald method to identify best independent predictors of death. The possibilities of interactions (effect measure modification) among independent variables were explored by including interaction terms in the multivariable Cox regression. P-value of less than 0.05 at 95% confidence interval was considered as a statistical significance to identify independent predictors of earlier death in multivariable analysis. Hazard Ratio (HR) was used as a measure of association.
The majority 320 (94.1%) of children were newly admitted, 16 (4.7%) readmission and 4(1.2%) were others. Regarding admission criteria 71(20.9%) were WFH < 70%, 106(31.2%) edematus, 86(25.3%) by MUAC and severe wasting were 58(17.1%). More than half of children’s under the cohort had no recorded information on breast fed (52.9%) and complementary feeding (57.1%). About three folds of children 252(74.1%) had no record of the amount per feed on the therapeutic milk. In the majority of charts reviewed; mothers or caregivers 277 (66.8%) have no recorded information, whether they had received a health nutrition education at discharge or not and it was given only for 88 (25.9%). Thus, these variables were excluded from final analysis.
Regarding routine medications; more than half of children 175(51.5%) were given antibiotics; 166(48.8%) Vitamin A and folic acid 5mg in 161(47.4%). Ninety-seven (28.5%) were Iv-infused (resuscitated with IV fluid), RESOMAL was given in 108(31.8%), NG-tube for feeding inserted for 154(45.3%), and 18(5.3%) were transfused with whole blood, while, deworming at Phase II was not given in 225(66.2%). Similarly, some medications that national SAM management guideline recommends to supply or treat complicated SAM were not implemented for some of the cases. Thus, this may also be due to irregular of supply or adherence to treat SAM may not supervised by external bodies.

The result of treatment outcome showed that cure rate and mortality rate were around the lowest and highest margin of acceptable level of the national SAM management guideline for inpatient care respectively. Both of these conditions need more attention to reverse; thus, this finding is alarming result to work hard and monitor performance [18] (Table 3).

Children with hypothermia, had 11.8 times increased risk of dying when compared to children with complicated SAM with normal temperature (AHR=11.8, 95% CI [3.77-37.02], P < 0.0001). Similarly, children having sepsis at admission had 2.9 times more at risk of death when compared to those with no sepsis (AHR=2.9, 95% CI [1.03-8.40], P = 0.045,) (Table 4). In addition, regarding routine medications; children who did not have antibiotics at admission 3.7 times more at risk of death (AHR=3.7, 95% CI [1.55-8.64], P=0.003) compared to those had had it (Table 4). The cumulative probability of survival by the end of the 3rd , 6th and the 9th -day was 94%, 92%, and 91% respectively. The probability of survival decline by 2% for the second three days, then by 1 % for next three days. Thus , the risk of death was very high within the first few days of hospital stay(Figure 5).
The probability of survival by the end of 3rd, 6th, and the 9th-day for age groups less than 6 months was 95%, 88%, and 88%; for 6 to 23 months 94%, 92% and 89%; and greater than 24 months was 93% for three respective days. These realize that the probability of survival was very low among young age groups than older ones.
The probability of survival by the end of the 3nd , 6th and 9th day children from rural was 93%, 90%, and 90%, whereas, 96%, 96%, and 93% for urban respectively (Figure 6). Thus, even though it has no significant association with mortality, especial attention has to be given for younger children and for rural residents who admitted to hospitals with complicated SAM.
Regarding the type of SAM, marasmus was the most prevalent 209(61.5%) one type of SAM. This finding is in line with the study done in Dhaka city of Bangladesh (61%) [22]. But the result was lower than a study conducted in southern Ethiopia were (47%) of the cases were marasmic [23]. Edematous type of SAM was 131(38.5% ) in the study and it was higher than the study done in Niger (15%) but by far lower than the study done in Jimma (57.2%) and Southern Ethiopia (53%) of the participants were having nutritional edema [2,11,24]. This may be due to the difference in socio-economic and cultural practices in different parts of the study areas. Diarrhea was the most prevalent 162 (47.6%) co-morbidity in SAM cases under the study followed by pneumonia, dehydration, malaria, clinical form of TB, severe anemia and hyperthermia with their respective prevalence being (31.5%), (21.2%), (19.1%), (12.9%), (8.5%) and (5.0%). But none of these variables were statistically significant predictors of mortality.

The overall mortality rate of the cohort is 8.8%. Many studies conducted in different countries; in Zambia (40.1%), Tanzania (13.7%), North Ethiopia (28.7%), and North West Ethiopia (11.7%) were shown higher incidence of mortality [22, 24, 26, 27]. The study result is comparable with the study reports of death at Sc from Southwestern Ethiopia (9.3%) [11]. this may be due to variation in the study settings, socioeconomic, maternal or caregivers commitment to take care accordingly and or literacy level [28].
However, the cure rate and mortality rate were in the margin of minimum acceptable of SAM guideline; the percentage of self-discharge, average weight gain and length of hospital stay of children in the SC of the study were also efficiently harmonizing with national SAM management guideline. The percentage of children who died (8.8%) was also in line with the minimum acceptable level of national SAM management guideline at stabilization centers (< 10%) [19].

Children having sepsis were 2.936 (95% CI [1.03-8.40], 0.045) times more at risk of death when compared with those who have no sepsis. The finding agrees’ with research conducted in University of Nigeria Teaching Hospital having sepsis with other co-morbidities shown a significant association with death in SAM patients in SC [4]. In addition, the result reported from Dhaka showed that septic children with complicated SAM were 11.7 ([5.8-23.9] 0.01) times more at risk of death compared with nonseptic [3]. In children with complicated SAM and having sepsis, the risk of dying may be more than double in countries like Ethiopia with limited resources. Because having SAM alone
On the other hand, children not having antibiotics at admission were by 3.7(95%CI [1.55, 8.64] p = 0.003) times more likely to die than those had had it. Research conducted in Nigeria contradicting this reported that resistance of enterobacteria to oral antibiotics and sensitivity to respond for third generation cephalosporin drugs [29]. Therefore, it may need another longitudinal study to confirm the drug sensitivity and response.
World Health Organization (WHO) recommends ten basic steps to manage SAM. Managing Hypothermia is the second most important recommendation in children with complicated SAM [30]. Therefore, the factors statistically significant association with the incidence rate of death as mentioned early may be due to poor adherence to guideline for management of SAM and medical complications, performing its management by untrained clinicians and SC setup factors. But this is out of the scope our study and may need a longitudinal prospective study.
The incomplete nature of secondary data and inappropriate keeping of old registration books, missing to record some charts by ward log bocks a non estimated limitation and patient’s chart made a sample size smaller. Despite these limitations, the study contributes important scientific evidence on factors compromising the survival of children admitted for treatment of complicated SAM in Wolaita.
• Health care providers working at the SC should give more attention to treat hypothermia by the bases of SAM management protocol.
• Provision of antibiotics at admission for septic children is obligatory in order to decline or halt early death.
• Zonal health department should strengthen the regular training to update the knowledge of SC staffs, death audit system and supply management for further improvement of complicated SAM outcome.
• Federal level guideline should be updated and Policy-makers should emphasis on close monitoring and evaluation of the utilization of the guideline and effectiveness of the implementation. In addition, encouraging non-governmental organizations to work on the objectives to reduce the mortality rate due to complicated SAM may also be paramount useful.
