Early Diagnosis of Cerebral Palsy in Low- and Middle-Income Countries

Factors associated with mortality and neurodevelopmental impairment at 12 months in asphyxiated newborns: a retrospective cohort study in rural Tanzania from January 2019 to June 2022

BACKGROUND

Worldwide about 2.3 million newborns still die in the neonatal period and the majority occurs in low- and middle-income countries (LMICs). Intrapartum-related events account for 24% of neonatal mortality. Of these events, intrapartum birth asphyxia with subsequent neonatal encephalopathy is the main cause of child disabilities in LMICs. Data on neurodevelopmental outcome and early risk factors are still missing in LMICs. This study aimed at investigating the factors associated with mortality, risk of neurodevelopmental impairment and adherence to follow-up among asphyxiated newborns in rural Tanzania.

METHODS

This retrospective observational cohort study investigated mortality, neurodevelopmental risk and adherence to follow-up among asphyxiated newborns who were admitted to Tosamaganga Hospital (Tanzania) from January 2019 to June 2022. Neurodevelopmental impairment was assessed using standardized Hammersmith neurologic examination. Admission criteria were Apgar score < 7 at 5 min of life and birth weight > 1500 g. Babies with clinically visible congenital malformations were excluded. Comparisons between groups were performed using the Mann-Whitney test, the Chi-square test, and the Fisher test.

RESULTS

Mortality was 19.1% (57/298 newborns) and was associated with outborn (p < 0.0001), age at admission (p = 0.02), lower Apgar score at 5 min (p = 0.003), convulsions (p < 0.0001) and intravenous fluids (IV) (p = 0.003). Most patients (85.6%) were lost to follow-up after a median of 1 visit (IQR 0-2). Low adherence to follow-up was associated with female sex (p = 0.005). The risk of neurodevelopmental impairment at the last visit was associated with longer travel time between household and hospital (p = 0.03), female sex (p = 0.04), convulsions (p = 0.007), respiratory distress (p = 0.01), administration of IV fluids (p = 0.04), prolonged oxygen therapy (p = 0.004), prolonged hospital stay (p = 0.0007) and inappropriate growth during follow-up (p = 0.0002).

CONCLUSIONS

Our findings demonstrated that mortality among asphyxiated newborns in a rural hospital in Tanzania remains high. Additionally, distance from home to hospital and sex of the newborn correlated to higher risks of neurodevelopmental impairment. Educational interventions among the population about the importance of regular health assessment are needed to improve adherence to follow-up and for preventive purposes. Future studies should investigate the role of factors affecting the adherence to follow-up.

Clinical Factors Related to Abnormal General Movements Trajectories: Development of a Multicriteria Index

PURPOSE

To create a multicriteria index with clinical factors associated with abnormal general movements (GMs) trajectories during a stay in the neonatal intensive care unit.

METHODS

A longitudinal study assessed abnormal GMs trajectories in preterm infants in the neonatal intensive care unit. The multicriteria index included clinical factors such as intraventricular hemorrhage, respiratory support, gestational age, patent ductus arteriosus, and infection based on multi-attribute utility theory.

RESULTS

A total of 52 preterm newborns, 57.7% male, were evaluated. The multicriteria index correlated with abnormal GMs trajectories and explained 26.5% of the variance in these trajectories.

CONCLUSION

The developed multicriteria index, with the inclusion of combined clinical factors, allowed the identification of part of the abnormal trajectories of GMs in preterm infants. The multicriteria analysis can help clinicians to identify infants who have a greater chance of poor developmental trajectories before hospital discharge.

Epidemiology of cerebral palsy among children in Ghana

Background

The epidemiology of cerebral palsy (CP) is poorly described in Ghana. These data are crucial for evidence-based intervention for children with CP in the country.

Objectives

We aimed to describe the epidemiology of CP among children in Ghana.

Method

We established the first institution-based register of children with CP in Ghana (Ghana CP Register-GCPR). Children with confirmed CP aged < 18 years were registered following a detailed neurodevelopmental assessment. Socio-demographics, risk factors, predominant motor type and topography, gross motor function classification system (GMFCS), associated impairments, education and rehabilitation status were documented.

Results

Between October 2018 and February 2020, 455 children were registered (mean [standard deviation {s.d.}] age at assessment: 5.9 [4.1] years). Preterm birth and low birthweight were reported in 52.0% and 21.1% children respectively. Most children (79.6%) had a pre- or perinatally acquired CP and the mean (s.d.) age of CP diagnosis was 22.2 (21.6) months. Overall, 55.9% of children had spastic tri- or quadriplegia, 60.5% had GMFCS level III-V and 70.3% had ≥ 1 associated impairment. However, 20.5% had never received rehabilitation services and 69.6% of school-aged children in the GCPR were not enrolled in schools.

Conclusion

The study findings indicate a high burden of severe motor and associated impairment among children with CP in Ghana which highlights the need for tailored interventions to improve health and well-being of children with CP in the country.

Contribution

The study highlights the need for interventions to improve functional outcome, health and well-being of children with CP in Ghana.

Evidence-Based Infant Assessment for Cerebral Palsy: Diagnosis Timelines and Intervention Access in a Newborn Follow-up Setting

Evidence-based assessment pathways inform early detection of cerebral palsy and access to intervention. This study investigated the relationships between early evidence-based assessments, diagnosis timeline, and rehabilitation intervention access in a population of children with cerebral palsy who were seen between 2010 and 2022 at the University of Wisconsin Waisman Center Newborn Follow Up Clinic. Cerebral palsy-specific assessments were increasingly integrated after the publication of early detection guidelines by Novak et al. in 2017. Age at cerebral palsy first mention (high risk for cerebral palsy) decreased over time, although age at diagnosis remained similar. Infants who received multiple evidence-based assessments were diagnosed at a younger age. Ninety-nine percent of children were referred to rehabilitation therapies before diagnosis. Infant age at referral to outpatient therapies decreased over time. This study provides novel clinical data on diagnosis timelines and identifies remaining gaps related to implementation feasibility toward improved early diagnosis and intervention access.

Hybrid developmental follow-up for preterm infants in Brazil: A feasibility study

INTRODUCTION

The low attendance of families in child developmental follow-up programs for at-risk preterm children is a challenge in Brazil.

OBJECTIVE

This study evaluates the feasibility of implementing a developmental follow-up program for Brazilian preterm infants in a hybrid format.

METHODS

This is an observational, prospective cohort study, involving preterm infants. Longitudinal developmental test results, the participation frequency in the program, and the number of referrals to early intervention programs were used to assess feasibility. The General Movements (GMs) assessment, Alberta Infant Motor Scale (AIMS) and, Survey of Wellbeing of Young Children (SWYC) Milestones were administered via telehealth. The Bayley-III was administered in-person.

RESULTS

Thirty-four preterm infants attended the follow-up until 12 months of corrected age and 18 (52.9 %) concluded all follow-up assessments. Twenty-six (76.5 %) attended all assessments via telehealth, and 26 (76.5 %) attended the in-person assessment. Eighteen (52.9 %) infants showed at least one altered result in development tests. Infants exhibiting abnormal results in the GMs assessment, motor developmental delay according to the AIMS, or developmental delay based on Balley-III were promptly referred to early intervention services.

CONCLUSION

This study demonstrated high participation rate and low dropout in a developmental follow-up program employing a hybrid format. The substantial number of identified infants with developmental delay emphasizes the importance of timely detection of motor delays to referral to early intervention services.

'We did everything by phone': a qualitative study of mothers' experience of smartphone-aided screening of cerebral palsy in Kathmandu, Nepal

BACKGROUND

International guidelines recommend early intervention to all children at risk of cerebral palsy, but targeted screening programs are often lacking in low- and middle-income settings with the highest burden of disease. Smartphone applications have the potential to improve access to early diagnostics by empowering parents to film their children at home followed by centralized evaluation of videos with General Movements Assessment. We explored mothers' perceptions about participating in a smartphone aided cerebral palsy screening program in Kathmandu, Nepal.

METHODS

This is an explorative qualitative study that used focus group discussions (n = 2) and individual interviews (n = 4) with mothers of term-born infants surviving birth asphyxia or neonatal seizures. Parents used the NeuroMotion™ smartphone app to film their children at home and the videos were analysed using Precthl's General Movements Assessment. Sekhon et al.'s framework on the acceptability of health care interventions guided the design of the group discussions and interviews, and the deductive qualitative content analysis.

RESULTS

Mothers were interested in engaging with the programme and expressed hope it would benefit their children. Most felt using the app was intuitive. They were, however, unclear about the way the analysis was performed. Support from the research team was often needed to overcome an initial lack of self-confidence in using the technology, and to reduce anxiety related to the follow-up. The intervention was overall perceived as recommendable but should be supplemented by a face-to-face consultation.

CONCLUSION

Smartphone aided remote screening of cerebral palsy is acceptable in a lower middle-income population but requires additional technical support.

Early Detection and Intervention for Children with High Risk of Cerebral Palsy: A Survey of Physical Therapists and Occupational Therapists in Brazil

AIMS

The purpose of this study was to assess the current clinical practice of physiotherapists and occupational therapists on early detection and early intervention for children with cerebral palsy (CP) in Brazil.

METHODS

This was a cross-sectional study. A purpose-developed electronic survey was disseminated across the country to physiotherapists and occupational therapists working with young children with or at risk of CP.

RESULTS

A total of 205 anonymous respondents were included. Most participants (64.4%) agree that the diagnosis of CP can be made before 6 months of age. General Movements Assessment (26.8%) and Hammersmith Infant Neurological Examination (37.1%) were used infrequently. Infants at risk for CP receive therapy twice a week or more by 58.5% of therapists, 93.2% identified parents' goals as the most important factor in customizing the early intervention program. The most frequent intervention strategies for this age group were active stimulation of the child (n = 182), family training (n = 161), strategies to optimize the environment (n = 143), and neurodevelopmental treatment/Bobath (n = 99).

CONCLUSIONS

Currently, pediatric physiotherapists and occupational therapists in Brazil do not fully incorporate best practice tools for early identification of children with CP, nor sufficient best evidence-based interventions.

NeuroMotion smartphone application for remote General Movements Assessment: a feasibility study in Nepal

OBJECTIVES

To evaluate the feasibility of using the NeuroMotion smartphone application for remote General Movements Assessment for screening infants for cerebral palsy in Kathmandu, Nepal.

METHOD

Thirty-one term-born infants at risk of cerebral palsy due to birth asphyxia or neonatal seizures were recruited for the follow-up at Paropakar Maternity and Women's Hospital, 1 October 2021 to 7 January 2022. Parents filmed their children at home using the application at 3 months' age and the videos were assessed for technical quality using a standardised form and for fidgety movements by Prechtl's General Movements Assessment. The usability of the application was evaluated through a parental survey.

RESULTS

Twenty families sent in altogether 46 videos out of which 35 had approved technical quality. Sixteen children had at least one video with approved technical quality. Three infants lacked fidgety movements. The level of agreement between assessors was acceptable (Krippendorf alpha 0.781). Parental answers to the usability survey were in general positive.

INTERPRETATION

Engaging parents in screening of cerebral palsy with the help of a smartphone-aided remote General Movements Assessment is possible in the urban area of a South Asian lower middle-income country.
