To enhance the capacity for early and effective management of genital tract infections at primary and secondary levels of the healthcare system, we developed a prediction model, validated internally to help predict individual risk of self-reported genital tract infections (sGTIs) at the community level in Ghana. The study involved 32973 men and women aged 15-49 years from three rounds of the Ghana Demographic Health Survey, from 2003 to 2014. The outcomes were sGTIs.

Introduction: In sub-Saharan Africa (SSA), an adequate supply of safe blood for transfusion is a major developmental challenge. In Ghana, deferral from blood donation for anemia accounts for nearly half of the ineligible blood donors. We conducted a longitudinal two-arm parallel-group non-inferiority trial to test if iron supplementation among blood donors with iron deficiency (ID) or anemia could increase their hemoglobin levels to near those without ID or anemia.

Background: Ghana adopted the Integrated Disease Surveillance and Response (IDSR) system, which is an integration of the various programs in the surveillance system and can contain disease outbreaks and pandemics. Implementation of the IDSR is influenced by several factors which can affect its functionality and ability to contain disease outbreaks. This study assessed the factors influencing the IDSR system in selected districts in the Eastern Region of Ghana.

Cardiovascular diseases (CVD) are the leading cause of death worldwide, with 80% of these deaths occurring in low-middle income countries (LMICs). In Ghana and across Africa, CVDs have emerged as the leading causes of death primarily due to undetected and under treated hypertension, yet less than 5% of resources allocated to health in these resource-poor countries go into non-communicable diseases (NCD) including CVD prevention and management. Consequently, most countries in Africa do not have contextually appropriate and sustainable health system framework to prevent, detect and manage CVD to achieve Universal Health Coverage (UHC) in CVD care through improved Primary Health Care (PHC) with the aim of achieving Sustainable Development Goals (SDG) in CVD/NCD.

  • - The study aimed to evaluate the effectiveness of cardiovascular physical examination (CPE) as a screening method for congenital heart disease (CHD) in newborns at Korle Bu Teaching Hospital in Accra, Ghana.
  • - Over eight months, 1,607 newborns were screened, with 52 showing signs of CHD through CPE, and 20 confirmed cases identified via echocardiogram; significant indicators included heart murmurs and dysmorphism.
  • - Results indicated that CPE is a reliable and cost-effective screening tool for CHD in low-resource settings, demonstrating high sensitivity (95%) but lower specificity (60.7%).

With limited social security and health protection in Ghana, intergenerational support is needed by those living with NCDs, who incur recurrent costs when seeking NCD care. We measured the level of informal support received by NCD patients and identified factors that influence support provision. We surveyed 339 NCD patients from three hospitals in Ghana, who listed their social ties and answered questions about their relationship and support frequency.

Background: The variations in health between rural and urban population have become an increasingly significant public health concern in developing countries including Ghana where urbanization is occurring. Whereas urbanization results in improved access to healthcare services, the concomitant negative consequences of urbanization coupled with unfavorable compositional and contextual attributes can affect the health of populations. The study sought to examine the effect of rural-urban residence and selected socio-demographic factors on perceived health state among aging population by employing a nationally representative data collected by the WHO from 2014 to 2015.
