Predictors of duration and treatment failure of severe pneumonia in hospitalized young Nepalese children

Time to recovery from severe community-acquired pneumonia and its predictors among 6 to 59 months of age children admitted to South Wollo zone public hospitals, North East Ethiopia: a prospective follow-up study

INTRODUCTION

Ethiopia is one of those countries with higher burden of community acquired pneumonia among its people, under five children are the members of society that are highly affected by pneumonia particularly Severe Community Acquired Pneumonia. However, there are limited studies on time to recovery and its predictors in under-five children and most of them are retrospective which fails to address important variables that affect the time to recovery. Therefore, the aim of this study was to estimate the median time to recovery and its predictors among under five children admitted to South Wollo zone public hospitals, North East Ethiopia.

METHODS

An institution-based prospective cohort study was conducted from March 10 to May 10, 2021, with 270 study subjects. A systematic random sampling technique was used. Data was collected by interview and chart review. The data were entered and analyzed using Epi Data version 3.1 and STATA version 14.0, respectively. Kaplan-Meier and Cox regression models were used to test the time and predictors of recovery from severe community-acquired pneumonia.

RESULTS

The overall incidence of recovery rate (95% confidence interval) from Severe Community-Acquired Pneumonia was 20.45(17.84-23.46) per 100 person days observation with median (IQR) time to recovery of [3, 5] days. The predictors of time to recovery from Severe Community-Acquired Pneumonia were having comorbidities on admission [AHR = 0.49 (95%CI: 0.32,0.75)], reaching hospitals after 5 days of onset of symptoms [AHR = 0.35 (95%CI: 0.20,0.60)], having Middle Upper Arm Circumference < = 12.5 cm [AHR = 0.21 (95%CI: 0.12,0.37)], the presence of smoker in the house [AHR = 0.21 (95%CI: 0.10,0.42)] and being not fully immunized for age [AHR = 0.35 (95%CI: 0.24,0.53)].

CONCLUSION AND RECOMMENDATIONS

Generally the recovery time of children with Severe Community Acquired Pneumonia in the study area was within the recommended national standards. Due attention should be given to children with the identified predictors while treating them.

Time to recovery and its predictors among under-five children admitted with severe pneumonia in East Wallaga Zone public hospitals, western Ethiopia, 2023; a retrospective cohort study

BACKGROUND

Globally, pneumonia is one of the leading causes of morbidity and mortality as well as hospitalization burden for under-five children. Despite significant initiatives implemented to reduce morbidity and mortality from pneumonia in under-five children, little is known regarding the time to recovery and its predictors among under-five children admitted with severe pneumonia in Ethiopia. Hence, this study intended to estimate the median time to recovery and its predictors among under-five children admitted with severe pneumonia in East Wallaga zone public hospitals, western Ethiopia; 2023.

METHODS

An institution-based retrospective cohort study was conducted among 383 under-five children who were admitted with severe pneumonia in East Wallaga zone public hospitals from January 2017 to December 2022. A systematic sampling method was used to select eligible medical records. EpiData Version 4.6 was used to enter the data and analyzed using STATA Version 17.0. Cox-proportional hazard assumption test and model fitness were checked. Variables with P-value ˂ 0.25 at bivariable Cox regression analysis were selected for the multivariable Cox proportional model. A multivariable Cox regression model with 95% CI and Adjusted Hazard Ratio (AHR) was used to identify a significant predictor of time to recovery from severe pneumonia at a P-value < 0.05.

RESULTS

At the end of the follow-up, 356 observations were developed an event (recovered) with the median time to recovery of 4 days with IQR of 3-5 days. The overall incidence rate of recovery was 22.26 per 100 (95% CI: 20.07-24.70) person-days observations. Being rural residency (AHR: 0.75, 95% CI: 0.60-0.93), late presenters for seeking care (AHR = 0.70, 95% CI: 0.53-0.93), presence of danger sign at admission (AHR = 1.46, 95% CI: 1.15-1.83), and presence of comorbidity (AHR = 1.63, 95% CI, 1.31-2.04) were found to have a statistically significant association with prolonged recovery time.

CONCLUSION

The median time to recovery from severe pneumonia was long, and factors such as Residence, co-morbidity, presence of danger signs, and duration prior to seeking care were statistically significant predictors of recovery time from severe pneumonia. Hence, due attention has to be given to increasing the community's health-seeking behavior to visit health facility early and especial attention should be given for children with danger signs and comorbidity.

Recovery Time From Severe Community Acquired Pneumonia and Risk Factors Among Pediatrics, Ethiopia: A Retrospective Follow-Up Study

Introduction. Severe community acquired pneumonia (CAP) is a life-threatening condition, with high rates of morbidity and mortality. This study aimed to determine the recovery time from severe CAP and risk factors among pediatric patients. Methods. A retrospective follow-up study was conducted among 412 pediatric medical charts with severe CAP enrolled at Asella Referral and Teaching Hospital between January 01, 2021 and December 31, 2022. EpiData version 4.6.0.6 and STATA version 14.2 were used for data entry and statistical analysis, respectively. Bivariable and multivariable Cox proportional hazards regression analyzes were performed. Result. The median recovery time from severe CAP among pediatric patients was 5 days (IQR = 3-8 days). IDR of recovery from severe CAP was 13.089 per 100 [95%CI: 11.82, 14.49] pediatric days observations. The cumulative incidence of recovery from severe CAP was 89.56% [n = 369, 95%CI: 86.20, 92.18]. Age [AHR = 1.55, 95%CI: 1.12, 2.13, P = .007], vaccination status [AHR = 1.29, 95%CI: 1.03, 1.63, P = .027], presence of danger signs [AHR = 1.61, 95%CI: 1.26, 2.05, P = .000], presence of comorbidity [AHR = 1.67, 95%CI: 1.33, 2.10, P = .000], duration of seeking care [AHR = 1.71, 95%CI: 1.18, 2.47, P = .004], and oxygen therapy [AHR = 1.45, 95%CI:1.12, 1.87, P = .004] were statistically significant risk factors for recovery time from severe CAP. Conclusions. The median recovery time of patients with severe CAP is relatively high. Age, vaccination status, presence of danger signs, presence of comorbidities, duration of seeking care, and oxygen therapy were statistically significant risk factors of recovery time from severe CAP.

Predictors of recovery time from severe community-acquired pneumonia among paediatrics patients in selected hospitals in Addis Ababa, Ethiopia: an institution-based retrospective cohort study

OBJECTIVE

Severe community-acquired pneumonia (SCAP) is a significant cause of morbidity worldwide and a major cause of morbidity and mortality in developing countries. Ethiopia ranks 6th out of 15 countries with the highest mortality rate due to pneumonia in children under 5 years of age. The aim of this study was to determine the recovery time from SCAP and factors in paediatric patients in selected hospitals in Addis Ababa.

DESIGN, PARTICIPANTS AND SETTING

A retrospective cohort study was conducted among 407 randomly selected paediatric patients admitted with SCAP in Addis Ababa public hospitals from 1 January 2018 to 31 December 2020.

PRIMARY AND SECONDARY OUTCOMES

Recovery time and recovery rate from SCAP were estimated using Kaplan-Meier and simple frequency statistics, respectively, and the adjusted HR with a 95% CI was used to identify associated factors for recovery.

RESULTS

91.5% (95% CI: 88.3% to 94.1%) of children recovered from SCAP with an overall recovery rate of 11.5 (95% CI: 10.37 to 12.76) per 100 person-day observation, and the median recovery time was 6 days. In the multivariable analysis, older age and the absence of comorbidities were protective factors for early recovery, while stunting and late utilisation of medical care were risk factors.

CONCLUSION

The median recovery time after SCAP was very long compared with the optimal recovery time of 3 days given in the British Thoracic Society guidelines. Older age and absence of comorbidities were found to shorten recovery time, whereas stunting and late initiation of treatment delayed recovery. Therefore, measures that increase the recovery rate and shorten the recovery time, such as primary prevention to eliminate malnutrition and increase the utilisation of medical care in the community, should be strengthened, and health workers should focus on the early detection and treatment of comorbid diseases.

Joint modeling of longitudinal changes of pulse rate and body temperature with time to recovery of pneumonia patients under treatment: a prospective cohort study

BACKGROUND

Pneumonia is the leading infectious cause of mortality worldwide and one of the most common lower respiratory tract infections that is contributing significantly to the burden of antibiotic consumption. The study aims to identify the determinants of the progress of pulse rate, body temperature and time to recovery of pneumonia patients.

METHOD

A prospective cohort study design was used from Felege Hiwot referral hospital on 214 sampled pneumonia patients from March 01, 2022 up to May 31, 2022. The Kaplan-Meier survival estimate and Log-Rank test was used to compare the survival time. Joint model of bivariate longitudinal and time to event model was used to identify factors of longitudinal change of pulse rate and body temperature with time to recovery jointly.

RESULT

As the follow up time of pneumonia patient's increase by one hour the average longitudinal change of pulse rate and body temperature were decreased by 0.4236 bpm and 0.0119 [Formula: see text]. The average longitudinal change of pulse rate and body temperature of patients who lived in rural was 1.4602 bpm and 0.1550 [Formula: see text] times less as compared to urban residence. Patients who had dangerous signs are significantly increased the average longitudinal change of pulse rate and body temperature by 2.042 bpm and 0.6031 [Formula: see text] as compared to patients who had no dangerous signs. A patient from rural residence was 1.1336 times more likely to experience the event of recovery as compared to urban residence. The estimated values of the association parameter for pulse rate and body temperature were -0.4236 bpm and -0.0119 respectively, which means pulse rate and body temperature were negatively related with patients recovery time.

CONCLUSION

Pulse rate and body temperature significantly affect the time to the first recovery of pneumonia patients who are receiving treatment. Age, residence, danger sign, comorbidity, baseline symptom and visiting time were the joint determinant factors for the longitudinal change of pulse rate, body temperature and time to recovery of pneumonia patients. The joint model approach provides precise dynamic predictions, widespread information about the disease transitions, and better knowledge of disease etiology.

Predictors of prolonged hospitalization among children aged 2-59 months with severe community-acquired pneumonia in public hospitals of Benishangul-Gumuz Region, Ethiopia: a multicenter retrospective follow-up study

Background

Pneumonia is a leading cause of morbidity and mortality among children aged under 5 years in Ethiopia. Prolonged hospitalization of severe community-acquired pneumonia is a significant problem in resource-limited countries. This study seeks to provide insights that can help improve the management and outcomes of severe community-acquired pneumonia, which is particularly important in the context of the Benishangul-Gumuz Region, Ethiopia, where access to quality healthcare services is limited, and childhood pneumonia is a significant health challenge.

Objective

The aim of the study was to determine the predictors of prolonged hospitalization among children aged 2-59 months admitted with severe community-acquired pneumonia between 1 January 2016 and 30 December 2020 in the public hospitals in Benishangul-Gumuz Region, Ethiopia.

Method

A retrospective follow-up study design was conducted among randomly selected samples of 526 children. Data were entered into EPI data version 4.6 and analyzed using STATA version 14.0. The Cox proportional hazard regression model was fitted to identify the independent predictors of prolonged hospitalization, and variables with a p-value <0.05 in the multivariable model were considered statistically significant.

Results

The median hospital stay was 5 days (interquartile range 2-8 = 6). Approximately 149 (28.93%) children had prolonged hospitalization (>5 days) and the recovery rate from severe community-acquired pneumonia was 19.69 per 100 person-day observations. The significant predictors of prolonged hospitalization were as follows: having facility referral sources [0.79, 95% confidence interval (CI), 0.63-0.98]; a nutritional status of wasting (0.64, 95% CI, 0.44-0.94); anemia (0.65, 95% CI, 0.46-0.90); no identified hemoglobin level (0.53, 95% CI, 0.41-0.70); no identified blood film (0.65, 95% CI, 0.53-0.80); no chest x-ray investigation (0.81, 95% CI, 0.65-0.99); pulmonary effusion (0.31, 95% CI, 0.15-0.66); and late presenters to hospital (0.67, 95% CI, 0.53-0.84) at admission.

Conclusions

The median length of stay in hospital was delayed compared to other studies. Wasting, late presenting to hospital, pulmonary effusion, anemia, absence of investigations of hemoglobin level, chest x-ray, and blood film at admission time were factors that significantly prolonged the hospitalization time. Hence, attention should be given to the prevention of malnutrition and anemia in children, increasing early health-seeking behavior in the community. Attention should be given to complications such as pleural effusion, and investigations, such as chest x-ray, hemoglobin levels, and blood films, should be performed when the child is admitted.

Low Mortality among Under-5 Children with Severe Community-Acquired Pneumonia: A 5-Year Retrospective Analysis of 588 Admissions in Ibadan, Nigeria

Objective Community-acquired pneumonia (CAP) is the commonest cause of death in under-5 children worldwide. Although the mortality from CAP has decreased over the last decade, it is still unacceptably high in lower-middle-income countries (LMICs). We aimed to determine the case fatality rate (CFR), and factors associated with treatment failure and outcome, using recommended antimicrobials.

Methods A 5-year retrospective review of severe pediatric pneumonia admissions between August 1st, 2014 and July 31st, 2019 at the University College Hospital, Ibadan, Nigeria was conducted. Relevant clinical information including antibiotics use and outcome was analyzed using descriptive statistics, test of association, and logistic regression.

Results There were 588 children aged 2 to 59 months, male:female ratio was 1.5:1. About two-thirds were aged ≤12 months. The majority were fully immunized for age (87.2%), about 34% were malnourished and 68% were hypoxemic at presentation. Only 71% of children were commenced on the recommended first-line antibiotics following the Pediatric Association of Nigeria (PAN) antibiotic guidelines. Initial antibiotics were changed in 22.3% of the patients. The need to change intravenous (iv) amoxicillin plus iv gentamicin was necessary in 23.80% compared with 18.1% for iv cefuroxime plus iv gentamicin. Severe acute malnutrition (odds ratio [OR]: 2.8 [95% confidence interval [CI]: 1.1–7.3]) and hypoxemia (OR:2.3 [95%CI: 1.0–5.6]) were independently associated with antibiotics change. The CFR was 1.36%.

Conclusion The low CFR suggests a better outcome compared with other previous studies in LMICs. However, the high rate of antibiotics changes (22.3%) was possibly due to failure of first line antibiotics; especially among malnourished and hypoxemic children. Randomized controlled trial of iv cefuroxime plus gentamicin versus iv amoxicillin plus gentamicin is recommended.

What are the risk factors for death among children with pneumonia in low- and middle-income countries? A systematic review

Background

Knowledge of the risk factors for and causes of treatment failure and mortality in childhood pneumonia is important for prevention, diagnosis, and treatment at an individual and population level. This review aimed to identify the most important risk factors for mortality among children aged under ten years with pneumonia.

Methods

We systematically searched MEDLINE, EMBASE, and PubMed for observational and interventional studies reporting risk factors for mortality in children (aged two months to nine years) in low- and middle-income countries (LMICs). We screened articles according to specified inclusion and exclusion criteria, assessed risk of bias using the EPHPP framework, and extracted data on demographic, clinical, and laboratory risk factors for death. We synthesized data descriptively and using Forest plots and did not attempt meta-analysis due to the heterogeneity in study design, definitions, and populations.

Findings

We included 143 studies in this review. Hypoxaemia (low blood oxygen level), decreased conscious state, severe acute malnutrition, and the presence of an underlying chronic condition were the risk factors most strongly and consistently associated with increased mortality in children with pneumonia. Additional important clinical factors that were associated with mortality in the majority of studies included particular clinical signs (cyanosis, pallor, tachypnoea, chest indrawing, convulsions, diarrhoea), chronic comorbidities (anaemia, HIV infection, congenital heart disease, heart failure), as well as other non-severe forms of malnutrition. Important demographic factors associated with mortality in the majority of studies included age <12 months and inadequate immunisation. Important laboratory and investigation findings associated with mortality in the majority of studies included: confirmed Pneumocystis jirovecii pneumonia (PJP), consolidation on chest x-ray, pleural effusion on chest x-ray, and leukopenia. Several other demographic, clinical and laboratory findings were associated with mortality less consistently or in a small numbers of studies.

Conclusions

Risk assessment for children with pneumonia should include routine evaluation for hypoxaemia (pulse oximetry), decreased conscious state (e.g. AVPU), malnutrition (severe, moderate, and stunting), and the presence of an underlying chronic condition as these are strongly and consistently associated with increased mortality. Other potentially useful risk factors include the presence of pallor or anaemia, chest indrawing, young age (<12 months), inadequate immunisation, and leukopenia.

Clinical Findings and Radiological Evaluation of WHO-Defined Severe Pneumonia Among Hospitalized Children

BACKGROUND

The leading infectious cause of death in children worldwide is pneumonia. Pneumonia claimed the lives of 740,180 kids under the age of five in 2019, accounting for 14% of all fatalities and 22% of deaths in kids between the ages of 1 and 5. Children and families worldwide are affected by pneumonia, but South Asia and Africa have the highest fatality rates.

OBJECTIVE

This study aims to determine the clinical risk factors and radiological assessment of the World Health Organization (WHO)-defined severe pneumonia in Pakistani hospitalized children.

MATERIAL AND METHODS

This cross-sectional study was carried out in the pediatric department of the Hayatabad Medical Complex between January 2021 and December 2021. The study included kids who had a fever, cough, and fast or difficulty breathing between the ages of 2 and 60 months. All of the included clinical pneumonia cases were acquired in the community.

RESULTS

A total of 360 clinically confirmed patients with pneumonia who presented with fever, cough, and fast or difficulty breathing were enrolled. Age ranged between 2 and 60 months, with a mean age of ±31 months. There were 168 (46.7%) males and 192 (53.3%) females. About 232 (64.4%) had radiological pneumonia, while the rest of the pneumonia cases 128 (35.5%) were without a radiological diagnosis. The most common presenting complaint was noisy breathing 119 (33%), followed by refusal of feeds 81 (22.5%), lethargy 69 (19.2%), seizure 40 (11.1%), nasal drainage 29 (8%), and abdominal pain 22 (6.1%).

CONCLUSION

The most specific clinical finding of radiographic pneumonia was bronchial breathing, while tachypnea was the most sensitive sign.

Joint modeling of longitudinal measures of pneumonia and time to convalescence among pneumonia patients: a comparison of separate and joint models

BACKGROUND

Globally, pneumonia is the leading cause of children under age five morbidity and mortality with 98% of deaths in developing countries.

OBJECTIVE

This study aimed to identify the determinants of longitudinal measures of pneumonia and time to convalescence or recovery of under five admitted pneumonia patients at Felege Hiwot Referral Hospital, Bahir Dar, Ethiopia.

METHODS

A prospective cohort study was conducted among a randomly selected sample of 101 pneumonia patients using simple random sampling who were on follow up from December 2019 to February 2020. A Linear mixed effect model were used for the longitudinal outcomes and joint model for modeling both longitudinal and time to event outcomes jointly respectively.

RESULTS

The significant values of shared parameters in the survival sub model shows that the use of joint modeling of multivariate longitudinal outcomes with the time to event outcome is the best model compared to separate models. The estimated values of the association parameters: - 0.297(p-value = 0.0021), - 0.121) (p-value = < 0.001) and 0.5452 (p-value = 0.006) indicates association of respiratory rate, pulse rate and oxygen saturation respectively with time to recovery. The significant values show that there is an evidence to say that there is a negative relationship between longitudinal measures of respiratory rate and pulse rate with time to recovery and there is positive relationship between longitudinal measures of oxygen saturation with time to recovery. Variables age, birth order, dangerous signs, severity and visit time were significant factors on the longitudinal measure of pulse rate. The significant factors related to longitudinal measures of oxygen saturation were birth order, severity and visit. From this we can conclude that birth order, severity and visit were significant variables that simultaneously affect the longitudinal measures of respiratory rate, pulse rate and oxygen saturation of patients at 5% level of significance.

CONCLUSION

Results of multivariate joint analysis shows that severity was significant variable that jointly affects the three longitudinal measures and time to recovery of pneumonia patients and we can conclude that patients with severe pneumonia have high values of respiratory rate and pulse rate as well as less amount of oxygen saturation and they need longer time to recover from the disease.

The utility of chest x-ray and lung ultrasound in the management of infants and children presenting with severe pneumonia in low-and middle-income countries: A pragmatic scoping review

Background

Chest x-ray (CXR) is commonly used (when available) to support clinical management decisions for child pneumonia and provide a reference standard for diagnosis in research studies. However, its diagnostic and technical limitations for both purposes are well recognised. Recent evidence suggests that lung ultrasound (LUS) may have diagnostic utility in pneumonia. This systematic scoping review of research on the utility of CXR and LUS in the management of severe childhood pneumonia aims to inform pragmatic guidelines for low- and middle-income countries (LMICs) and identify gaps in knowledge.

Methods

We included peer-reviewed studies published between 2000 and 2020 in infants and children aged from one month to nine years, presenting with severe pneumonia. CXR studies were limited to those from LMICs, while LUS studies included any geographic region. LUS and CXR articles were mapped into the following themes: indications, role in diagnosis, role in management, impact on outcomes, and practical considerations for LMIC settings.

Results

85 articles met all eligibility criteria, including 27 CXR studies and 58 LUS studies. CXR studies were primarily observational and examined associations between radiographic abnormalities and pneumonia aetiology or outcomes. The most consistent finding was an association between CXR consolidation and risk of mortality. Difficulty obtaining quality CXR images and inter-reader variability in interpretation were commonly reported challenges. Research evaluating indications for CXR, role in management, and impact on patient outcomes was very limited. LUS studies primarily focused on diagnostic accuracy. LUS had higher sensitivity for identification of consolidation than CXR. There are gaps in knowledge regarding diagnostic criteria, as well as the practical utility of LUS in the diagnosis and management of pneumonia. Most LUS studies were conducted in HIC settings with experienced operators; however, small feasibility studies indicate that good inter-operator reliability may be achieved by training of novice clinicians in LMIC settings.

Conclusions

The available evidence does not support the routine use of CXR or LUS as essential tools in the diagnosis and initial management of severe pneumonia. Further evaluation is required to determine the clinical utility and feasibility of both imaging modalities in low-resource settings.

Incidence of recovery from severe pneumonia and its predictors among children 2-59 months admitted to pediatric ward of Ayder Comprehensive Specialized Hospital, Tigray, Ethiopia: A retrospective Cohort study

Background

Pneumonia is a major reason for hospital admission among children, particularly in resource-poor areas. A hospital stay (length of stay) alone is found to contribute for 46.8% of a household cost for single episode of severe pneumonia. The aim of this study was to determine the incidence of recovery from severe pneumonia and predictors among children 2-59 months of age admitted to pediatric ward of Ayder Comprehensive Specialized Hospital (ACSH).

Methods

A retrospective facility-based cohort study was conducted among under-five-year-old children admitted in ACSH. Three years medical records from July 7, 2015 to July 6, 2018 were reviewed. A total of 285 children with severe pneumonia admitted to pediatric ward of ACSH were included. Kaplan-Meier Survival Curve was used to estimate recovery time. The independent effects of covariates on recovery time are analyzed using multivariate Cox-proportional adjusted model.

Result

The median survival time was four days (95% CI = 3.732 - 4.268). The incidence of recovery was 92.3%. Co-morbidity (AOR: 3.47, 95%CI, 2.21, 5.4), malnutrition (AOR = 1.9, 95%CI, 1.2, 3.1), duration of chief complaint (AOR = 0.72, 95%CI: 0.54, 0.94), and vaccination (AOR = 0.32, 95% CI, 0.13, 0.81) were significant predictors of time to recovery from severe pneumonia.

Conclusion

High recovery rate and short length of hospital stay was observed in this study. Increased duration of chief complaint, presence of co-morbidity, being malnourished, and vaccination were factors that associated with time to recovery. Therefore focuses have to be given in increasing the community's health seeking behavior to visit health facility early and especial attention should be given for children with co-morbidity, malnutrition, and unvaccinated children.

Prevalence of hypoxaemia in children with pneumonia in low-income and middle-income countries: a systematic review and meta-analysis

BACKGROUND

Pneumonia accounts for around 15% of all deaths of children younger than 5 years globally. Most happen in resource-constrained settings and are potentially preventable. Hypoxaemia is one of the strongest predictors of these deaths. We present an updated estimate of hypoxaemia prevalence among children with pneumonia in low-income and middle-income countries.

METHODS

We conducted a systematic review using the following key concepts "children under five years of age" AND "pneumonia" AND "hypoxaemia" AND "low- and middle-income countries" by searching in 11 bibliographic databases and citation indices. We included all articles published between Nov 1, 2008, and Oct 8, 2021, based on observational studies and control arms of randomised and non-randomised controlled trials. We excluded protocol papers, articles reporting hypoxaemia prevalence based on less than 100 pneumonia cases, and articles published before 2008 from the review. Quality appraisal was done with the Joanna Briggs Institute tools. We reported pooled prevalence of hypoxaemia (SpO2 <90%) by classification of clinical severity and by clinical settings by use of the random-effects meta-analysis models. We combined our estimate of the pooled prevalence of pneumonia with a previously published estimate of the number of children admitted to hospital due to pneumonia annually to calculate the total annual number of children admitted to hospital with hypoxaemic pneumonia.

FINDINGS

We identified 2825 unique records from the databases, of which 57 studies met the eligibility criteria: 26 from Africa, 23 from Asia, five from South America, and four from multiple continents. The prevalence of hypoxaemia was 31% (95% CI 26-36; 101 775 children) among all children with WHO-classified pneumonia, 41% (33-49; 30 483 children) among those with very severe or severe pneumonia, and 8% (3-16; 2395 children) among those with non-severe pneumonia. The prevalence was much higher in studies conducted in emergency and inpatient settings than in studies conducted in outpatient settings. In 2019, we estimated that over 7 million children (95% CI 5-8 million) were admitted to hospital with hypoxaemic pneumonia. The studies included in this systematic review had high τ2 (ie, 0·17), indicating a high level of heterogeneity between studies, and a high I2 value (ie, 99·6%), indicating that the heterogeneity was not due to chance. This study is registered with PROSPERO, CRD42019126207.

INTERPRETATION

The high prevalence of hypoxaemia among children with severe pneumonia, particularly among children who have been admitted to hospital, emphasises the importance of overall oxygen security within the health systems of low-income and middle-income countries, particularly in the context of the COVID-19 pandemic. Even among children with non-severe pneumonia that is managed in outpatient and community settings, the high prevalence emphasises the importance of rapid identification of hypoxaemia at the first point of contact and referral for appropriate oxygen therapy.

Chest radiography in children aged 2-59 months enrolled in the Innovative Treatments in Pneumonia (ITIP) project in Lilongwe Malawi: a secondary analysis

BACKGROUND

Pneumonia is the leading infectious cause of death in children aged under 5 years in low- and middle-income countries (LMICs). World Health Organization (WHO) pneumonia diagnosis guidelines rely on non-specific clinical features. We explore chest radiography (CXR) findings among select children in the Innovative Treatments in Pneumonia (ITIP) project in Malawi in relation to clinical outcomes.

METHODS

When clinically indicated, CXRs were obtained from ITIP-enrolled children aged 2 to 59 months with community-acquired pneumonia hospitalized with treatment failure or relapse. ITIP1 (fast-breathing pneumonia) and ITIP2 (chest-indrawing pneumonia) trials enrolled children with non-severe pneumonia while ITIP3 enrolled children excluded from ITIP1 and ITIP2 with severe pneumonia and/or selected comorbidities. A panel of trained pediatricians classified the CXRs using the standardized WHO CXR research methodology. We analyzed the relationship between CXR classifications, enrollee characteristics, and outcomes.

RESULTS

Between March 2016 and June 2018, of 114 CXRs obtained, 83 met analysis criteria with 62.7% (52/83) classified as having significant pathology per WHO standardized interpretation. ITIP3 (92.3%; 12/13) children had a higher proportion of CXRs with significant pathology compared to ITIP1 (57.1%, 12/21) and ITIP2 (57.1%, 28/49) (p-value = 0.008). The predominant pathological CXR reading was "other infiltrates only" in ITIP1 (83.3%, 10/12) and ITIP2 (71.4%, 20/28), while in ITIP3 it was "primary endpoint pneumonia"(66.7%, 8/12,; p-value = 0.008). The percent of CXRs with significant pathology among children clinically cured (60.6%, 40/66) vs those not clinically cured (70.6%, 12/17) at Day 14 was not significantly different (p-value = 0.58).

CONCLUSIONS

In this secondary analysis we observed that ITIP3 children with severe pneumonia and/or selected comorbidities had a higher frequency of CXRs with significant pathology, although these radiographic findings had limited relationship to Day 14 outcomes. The proportion of CXRs with "primary endpoint pneumonia" was low. These findings add to existing data that additional diagnostics and prognostics are important for improving the care of children with pneumonia in LMICs.

TRIAL REGISTRATION

ITIP1, ITIP2, and ITIP3 were registered with ClinicalTrials.gov ( NCT02760420 , NCT02678195 , and NCT02960919 , respectively).

Assessment of hospitalization costs and its determinants in infants with clinical severe infection at a public tertiary hospital in Nepal

Sepsis, an important and preventable cause of death in the newborn, is associated with high out of pocket hospitalization costs for the parents/guardians. The government of Nepal’s Free Newborn Care (FNC) service that covers hospitalization costs has set a maximum limit of Nepalese rupees (NPR) 8000 i.e. USD 73.5, the basis of which is unclear. We aimed to estimate the costs of treatment in neonates and young infants fulfilling clinical criteria for sepsis, defined as clinical severe infection (CSI) to identify determinants of increased cost. This study assessed costs for treatment of 206 infants 3–59 days old, enrolled in a clinical trial, and admitted to the Kanti Children’s Hospital in Nepal through June 2017 to December 2018. Total costs were derived as the sum of direct costs for bed charges, investigations, and medicines and indirect costs calculated by using work time loss of parents. We estimated treatment costs for CSI, the proportion exceeding NPR 8000 and performed multivariable linear regression to identify determinants of high cost. Of the 206 infants, 138 (67%) were neonates (3–28 days). The median (IQR) direct costs for treatment of CSI in neonates and young infants (29–59 days) were USD 111.7 (69.8–155.5) and 65.17 (43.4–98.5) respectively. The direct costs exceeded NPR 8000 (USD 73.5) in 69% of neonates with CSI. Age <29 days, moderate malnutrition, presence of any sign of critical illness and documented treatment failure were found to be important determinants of high costs for treatment of CSI. According to this study, the average treatment cost for a newborn with CSI in a public tertiary level hospital is substantial. The maximum limit offered for free newborn care in public hospitals needs to be revised for better acceptance and successful implementation of the FNC service to avert catastrophic health expenditures in developing countries like Nepal.

Time to Recovery from Severe Pneumonia and Its Predictors Among Children 2-59 Months of Age Admitted to Pediatric Ward of Nigist Eleni Mohammed Memorial Comprehensive Specialized Hospital, Hossana, Ethiopia: Retrospective Cohort Study

Background

Severe pneumonia is still the greatest infectious cause of morbidity and mortality in children under the age of five around the world. Each night spent in the hospital raises the chance of bad drug responses, infections, and ulcers by 0.5%, 1.6%, and 0.5%, respectively. In Southern Ethiopia, as well as the research area, little is known regarding death and recovery time from severe pneumonia and their determinants.

Objective

To determine time to recovery from severe pneumonia and its predictors among children 2–59 months of age admitted to pediatric ward of Nigist Eleni Mohammed Memorial Comprehensive Specialized Hospital.

Methods

A facility-based retrospective cohort study was conducted among children 2–59 months of age. Three years’ medical records, from January 2017 to December 2020, were reviewed. A total of 280 children with severe pneumonia were included. In the case of survival time, median was calculated. Kaplan Meier survival curve was used to estimate recovery time from severe pneumonia, and the independent effects of covariates on recovery time were analyzed using multivariable Cox-proportional hazard model.

Results

The median time to recovery was 4 days (interquartile range = 3, 5). The incidence rate of recovery was 24.16 per 100 person-days. Underweight (adjusted hazard ratio = 0.56, 95% CI = 0.38–0.80), age group 12–35 months (adjusted hazard ratio= 2.0, 95% CI=1.30–3.30), treatment with ampicillin and gentamicin (adjusted hazard ratio= 0.35, 95% CI: 0.13–0.80), and antibiotic change (adjusted hazard ratio= 0.34, 95% CI = 0.21–0.53) were statistically significant predictors of time to recovery from severe pneumonia.

Conclusion

The median length of stay in the hospital was short (4 days [interquartile range =3, 5]). Time to recover from severe pneumonia was significantly influenced by being underweight, age, antibiotics administered first, and antibiotic change. Measures such as providing nutritious meals to children and ensuring that underweight children are properly managed should be bolstered.

Time-to-Recovery from Severe Pneumonia and Its Determinants Among Children Under-Five Admitted to University of Gondar Comprehensive Specialized Hospital in Ethiopia: A Retrospective Follow-Up Study; 2015-2020

Background

Pneumonia, which is an infection and inflammation of an air-space in the lungs due to an impurity. Child mortality due to pheumonia is estimated at 921,000 children under 5 years (U5) in 2015.

Objective

To determine the TTR and factors of severe pneumonia among U5 children admitted at UOGCSH, Northwest Ethiopia.with

Methods

A facility-based retrospective follow-up study was conducted on children U5 severe pneumonia from 2015 to 2020. The data were collected using pre-test and structured questionnaires. Statistical analysis was performed using Stata version 14.1.

Result

The average TTR was 3 days IQR (3–6). TTR from severe pneumonia was 13.5 (95% CI: 13.54–17.15) per 100-persons. The cumulative time for children at risk was 1112 days, with a TTR of 29.7 per 100 children per day. Severity, signs and symptoms of pneumonia (AHR, 3.88 (95% CI =3.12–5.57)); mode of infancy feeding (cows milk feeding) (AHR, 2.4, (95% CI: 2.22–6.6)), and formula feeding (AHR, 0.68, (95% CI 0.58–1.25)) as compared to breastfeeding; nutritional status (underweight) (AHR, 2.2, (95% CI: (2.1–3.76)) as compared to normal, age (2–3-years) (AHR, 1.4, (95% CI: 1.31–2.22)), and ≥4-years (AHR, 1.32, (95% CI: 1.3–2.32)) as compared to age of ≤1 year were important factors of TTR.

Conclusion

The overall TTR was 3 days IQR (2–6). This study identifies severity, signs, and symptoms of pneumonia, Mode of infancy feeding (cows milk feeding, formula feeding), nutritional status, and age were main determinants of TTR.

Time to recovery and predictors of severe community-acquired pneumonia among pediatric patients in Debre Markos referral hospital, North West Ethiopia: A retrospective follow-up study

Introduction

Globally, pneumonia is a major cause of morbidity and mortality among children which leads to over 156 million episodes and 14.9 million hospitalizations each year. Besides this fact, the recovery time and predictors of children’s hospitalization related to severe community-acquired pneumonia is not well known. Therefore, the aim of this study was to estimate the median time to recovery and its predictors among severe community-acquired pneumonia patients admitted to the pediatric ward, Debre Markos referral hospital, North West Ethiopia.

Methods

An institution-based retrospective follow-up study was employed among 352 records of children who were admitted starting from January 2016 to December 2018. Patients' charts were retrieved using a structured data extraction tool. Cox proportional hazard model assumption and model fitness was checked. Stratified Cox regression was fitted as a final model. Hazard ratio with its 95% confidence interval was used and P-value < 0.05 was considered as a statistically significant association.

Result

The overall median recovery time was 4 days IQR (3–7). Recovery rate from severe community acquired pneumonia was 16.25 (95% CI: 14.54–18.15) per 100 person day observation. Age (AHR; 0.94 95% CI (0.90–0.98)), being stunted (AHR; 0.62 95% CI (0.43–0.91)), presence of danger sign at admission (AHR; 0.61 95% CI (0.40–0.94)), late presentation to seek care(AHR; 0.64 95% CI (0.47–0.88)) and co-morbidity (AHR; 0.45 95% CI (0.35–0.58)) were significant predictors of recovery time.

Conclusion

The median recovery time from severe community-acquired pneumonia was long so that measures to reduce recovery time should be strengthened.

Clinical predictors of radiological pneumonia: A cross-sectional study from a tertiary hospital in Nepal

Background

Despite readily availability of vaccines against both Hemophilus influenzae and Pneumococcus, pneumonia remains the most common cause of morbidity and mortality in children under the age of five years in Nepal. With growing antibiotic resistance and a general move towards more rational antibiotic use, early identification of clinical signs for the prediction of radiological pneumonia would help practitioners to start the treatment of patients. The main aim of this study was to reassess the clinical predictors of pneumonia in Nepal.

Methods

This cross-sectional study was conducted between June 2015 and November 2015 at Tribhuvan University Teaching Hospital, a tertiary hospital in Kathmandu, Nepal. Children aged 3–60 months with a clinical diagnosis of pneumonia by a physician were enrolled in the study. Radiological pneumonia was identified and categorized as per World Health Organization guidelines by an experienced radiologist blinded to patient characteristics. We calculated sensitivity and specificity of clinical signs and symptoms for radiological pneumonia.

Results

Out of 1021 children with fever, 160 cases were clinically diagnosed as pneumonia and were enrolled for this study. Among the enrolled patients, 61% had radiological pneumonia. Tachypnea had the highest sensitivity of 99%, while bronchial breathing had the highest specificity of 100%. During univariate analysis, grunting, wheezing, nasal discharge, decreased breath sounds, noisy breathing and hypoxemia were associated with radiological pneumonia. Only hypoxemia remained an independent predictor when adjusted for all the factors.

Conclusion

Tachypnea was the most sensitive sign, whereas bronchial breathing was most specific sign for radiological pneumonia.

Levofloxacin: Insights Into Antibiotic Resistance and Product Quality

Counterfeit and substandard medicines are recognized as one of serious threats to public health. The product quality of antibacterial medicine will compromise patients’ recovery and increase the chance of antibacterial resistance. The review aims to provide a summary of low quality levofloxacin issues and the risk factors as well as suggesting the aspects of product quality that need to be regulated strictly. Quality of the active ingredient, levofloxacin, has an important role to contribute to successful therapy. The poor quality of raw material, directly and indirectly, causes treatment failure as the presence of insufficient dose, mislabeled content, and poor dissolution characteristics can lead to lower bioavailability. Identifying and reporting these factors can potentially help in improving the quality of drug marketed in various developing countries and may also reduce the incidences of treatment failure. Dissolution test is used for testing the dissolution profiles and the rate of drug release from solid formulation such as oral formulations, thus providing information regarding the in vivo performance of a formulation and its bioequivalence. On the other hand, quality-testing procedures are used for comparing the quality of products.

Aetiology and risks factors associated with the fatal outcomes of childhood pneumonia among hospitalised children in the Philippines from 2008 to 2016: a case series study

OBJECTIVE

Pneumonia remains the leading cause of hospitalisations and deaths among children aged <5 years. Diverse respiratory pathogens cause acute respiratory infections, including pneumonia. Here, we analysed viral and bacterial pathogens and risk factors associated with death of hospitalised children.

DESIGN

A 9-year case series study.

SETTING

Two secondary-care hospitals, one tertiary-care hospital and one research centre in the Philippines.

PARTICIPANTS

5054 children aged <5 years hospitalised with severe pneumonia.

METHODS

Nasopharyngeal swabs for virus identification, and venous blood samples for bacterial culture were collected. Demographic, clinical data and laboratory findings were collected at admission time. Logistic regression analyses were performed to identify the factors associated with death.

RESULTS

Of the enrolled patients, 57% (2876/5054) were males. The case fatality rate was 4.7% (238/5054), showing a decreasing trend during the study period (p<0.001). 55.0% of the patients who died were either moderately or severely underweight. Viruses were detected in 61.0% of the patients, with respiratory syncytial virus (27.0%) and rhinovirus (23.0%) being the most commonly detected viruses. In children aged 2-59 months, the risk factors significantly associated with death included age of 2-5 months, sensorial changes, severe malnutrition, grunting, central cyanosis, decreased breath sounds, tachypnoea, fever (≥38.5°C), saturation of peripheral oxygen <90%, infiltration, consolidation and pleural effusion on chest radiograph.Among the pathogens, adenovirus type 7, seasonal influenza A (H1N1) and positive blood culture for bacteria were significantly associated with death. Similar patterns were observed between the death cases and the aforementioned factors in children aged <2 months.

CONCLUSION

Malnutrition was the most common factor associated with death and addressing this issue may decrease the case fatality rate. In addition, chest radiographic examination and oxygen saturation measurement should be promoted in all hospitalised patients with pneumonia as well as bacteria detection to identify patients who are at risk of death.

Vitamin D status is associated with treatment failure and duration of illness in Nepalese children with severe pneumonia

BackgroundThere is no consensus on optimal Vitamin D status. The objective of this study was to estimate the extent to which vitamin D status predicts illness duration and treatment failure in children with severe pneumonia by using different cutoffs for vitamin D concentration.MethodsWe measured the plasma concentration of 25(OH)D in 568 children hospitalized with World Health Organization-defined severe pneumonia. The associations between vitamin D status, using the most frequently used cutoffs for vitamin D insufficiency (25(OH)D<50 and <75 nmol/l), and risk for treatment failure and time until recovery were analyzed in multiple logistic regression and Cox proportional hazards models, respectively.ResultsOf the 568 children, 322 (56.7%) had plasma 25(OH)D levels ≥75 nmol/l, 179 (31.5%) had levels of 50-74.9 nmol/l, and 67 (%) had levels <50 nmol/l. Plasma 25(OH)D <50 nmol/l was associated with increased risk for treatment failure and longer time until recovery.ConclusionOur findings indicate that low vitamin D status (25(OH)D<50 nmol/l) is an independent risk factor for treatment failure and delayed recovery from severe lower respiratory infections in children.

Factors That Negatively Affect the Prognosis of Pediatric Community-Acquired Pneumonia in District Hospital in Tanzania

Community-acquired pneumonia (CAP) is still the most important cause of death in countries with scarce resources. All children (33 months ± 35 DS) discharged from the Pediatric Unit of Itigi Hospital, Tanzania, with a diagnosis of CAP from August 2014 to April 2015 were enrolled. Clinical data were gathered. Dried blood spot (DBS) samples for quantitative real-time polymerase chain reaction (PCR) for bacterial detection were collected in all 100 children included. Twenty-four percent of patients were identified with severe CAP and 11% died. Surprisingly, 54% of patients were admitted with a wrong diagnosis, which increased complications, the need for antibiotics and chest X-rays, and the length of hospitalization. Comorbidity, found in 32% of children, significantly increased severity, complications, deaths, need for chest X-rays, and oxygen therapy. Malnourished children (29%) required more antibiotics. Microbiologically, Streptococcus pneumonia (S. p.), Haemophilus influenza type b (Hib) and Staphylococcus aureus (S. a.) were the bacteria more frequently isolated. Seventy-five percent of patients had mono-infection. Etiology was not correlated with severity, complications, deaths, oxygen demand, or duration of hospitalization. Our study highlights that difficult diagnoses and comorbidities negatively affect clinical evolution. S. p. and Hib still play a large role; thus, implementation of current vaccine strategies is needed. DBS is a simple and efficient diagnostic method for bacterial identification in countries with scarce resources.

Chest Radiographic Findings and Outcomes of Pneumonia Among Children in Botswana

BACKGROUND

Chest radiography is increasingly used to diagnose pneumonia in low-income and middle-income countries. Few studies examined whether chest radiographic findings predict outcomes of children with clinically suspected pneumonia in these settings.

METHODS

This is a hospital-based, prospective cohort study of children 1-23 months of age meeting clinical criteria for pneumonia in Botswana. Chest radiographs were reviewed by 2 pediatric radiologists to generate a consensus interpretation using standardized World Health Organization criteria. We assessed whether final chest radiograph classification was associated with our primary outcome, treatment failure at 48 hours, and secondary outcomes.

RESULTS

From April 2012 to November 2014, we enrolled 249 children with evaluable chest radiographs. Median age was 6.1 months, and 58% were male. Chest radiograph classifications were primary endpoint pneumonia (35%), other infiltrate/abnormality (42%) or no significant pathology (22%). The prevalence of endpoint consolidation was higher in children with HIV infection (P = 0.0005), whereas endpoint pleural effusions were more frequent among children with moderate or severe malnutrition (P = 0.0003). Ninety-one (37%) children failed treatment, and 12 (4.8%) children died. Primary endpoint pneumonia was associated with an increased risk of treatment failure at 48 hours (P = 0.002), a requirement for more days of respiratory support (P = 0.002) and a longer length of stay (P = 0.0003) compared with no significant pathology. Primary endpoint pneumonia also predicted a higher risk of treatment failure than other infiltrate/abnormality (P = 0.004).

CONCLUSIONS

Chest radiograph provides useful prognostic information for children meeting clinical criteria for pneumonia in Botswana. These findings highlight the potential benefit of expanded global access to diagnostic radiology services.
