Predictors to parental knowledge about childhood immunisation/EPI vaccines in two health districts in Cameroon prior to the introduction of 13-valent Pneumococcal Conjugate Vaccines (PCV-13)

Knowledge, attitude and management of hearing screening in children among family physicians in the Kingdom of Saudi Arabia

BACKGROUND

Early detection and management of hearing loss are important to develop ordinary speaking language and academic skills during childhood. Lack of knowledge by either parents or health care providers could hinder the process of hearing loss diagnosis, such that the intervention will be less effective. There is little evidence about the knowledge and practice of family physicians regarding hearing screening in Saudi Arabia and worldwide.

OBJECTIVES

This study aimed to assess family physicians' knowledge, attitudes, and practices related to hearing loss in children. This in turn will help policy makers and educational institutions to establish and promote a program concerned with screening, diagnosis and intervention of paediatric hearing loss.

METHODS

A cross-sectional descriptive study enrolled 133 family physicians working at primary health centres in Saudi Arabia from March 2020 to September 2020. A self-reported questionnaire was used to assess the knowledge, attitudes, and practices of family physicians concerning hearing loss in children.

RESULTS

The majority of the participants were working under the umbrella of the Ministry of Health and around half of them did not screen any child for hearing loss. Despite that, 91.7% indicated the importance of neonatal hearing screening, 70.7% indicate infant candidacy for cochlear implant and only 33.1% know about the existence of the early hearing detection and intervention (EHDI) governmental program in kingdom of Saudi Arabia (KSA). Participants were able to identify factors associated with hearing loss such as a family history of hearing loss (85.6%), meningitis (75%) and craniofacial anomalies (51.5%). The most frequent specialists for patient referrals were ear nose and throat ENT (75.2%) and audiologists (67.7%).

CONCLUSION

This study shows that family physicians have good general background about the benefits of EHDI programs and the management of hearing loss in the paediatric population. However, it also indicated insufficient knowledge in other domains of hearing loss, including assessments and the presence of the EHDI governmental program in KSA. Further actions on the involvement of family physicians in the process of neonatal hearing screening, diagnosis and intervention for hearing impairment are needed.

Burden of vaccine-preventable diseases, trends in vaccine coverage and current challenges in the implementation of the expanded program on immunization: A situation analysis of Cameroon

The discovery and development of vaccines remain one of the major successes of global health with millions of lives saved every year through routine vaccination. Although vaccines provide a safe and cost-effective solution to vaccine-preventable diseases (VPDs), VPDs are still a serious public health problem in most parts of the world, especially in sub-Saharan Africa (SSA) and Asia. In this review, we discuss the burden of VPDs and vaccine coverage several decades after the introduction of the Expanded Program on Immunization (EPI) in Cameroon. We also discuss how different factors affect the implementation of the EPI, highlighting context-specific factors such as the ongoing civil conflict in Cameroon, and the presence of other infectious diseases like COVID-19.

Assessing the causes of under-five mortality and proportion associated with pneumococcal diseases in Cameroon. A case-finding retrospective observational study: 2006-2012

BACKGROUND

Vital registration data outlining causes of deaths (CoD) are important for a sustainable health system, targeted interventions and other relevant policies. There is data paucity on vital registration systems in developing countries. We assessed the leading causes and proportions of under-five deaths, and particularly those related to pneumococcal infections in Yaoundé, Cameroon, using hospital registration data.

METHODS

A retrospective case-finding observational study design was used to access and identify data on 817 death cases in children under-five years of age recorded in health facilities in Yaoundé, within the period January 1, 2006 and December 31, 2012. Patients' files were randomly selected and needed information including demographic data, date of admission, clinical and laboratory diagnosis, principal and/or underlying causes of death were abstracted into structured case report forms. The International Classification of Diseases and Clinical Modifications 10th revision (ICD-10-CM) codes (ICD10Data.com 2017 edition) were used to classify the different CoD, retrospectively. Ascertainment of CoD was based on medical report and estimates were done using the Kaplan-Meier procedure and descriptive statistics.

RESULTS

Of the 817 death records assessed, malaria was the leading CoD and was responsible for 17.5% of cases. Meningitis was the second largest CoD with 11.0%; followed by sepsis (10.0%), Streptococcus pneumoniae infections (8.3%), malnutrition (8.3%), gastro-enteritis / diarrhoea (6.2%), anaemia (6.1%) and HIV (3.5%), respectively.

CONCLUSION

The main CoD in this population are either treatable or vaccine-preventable; a trend consistent with previous reports across developing countries. Besides, the health effects from non-communicable infections should not be neglected. Therefore, scaling-up measures to reduce causes of under-five deaths will demand sustainable efforts to enhance both treatment and disease prevention strategies, to avoid a decline in the progress towards reducing under-five deaths by 2/3 from the 1990 baseline.
