Article Synopsis
  • The National Ambulance Service (NAS) of Ghana has significantly expanded its reach and capabilities over the last 20 years, increasing from 9 ambulances and 64 EMTs in 2004 to 356 ambulances and 3,473 EMTs by 2023, effectively covering every district in the country.
  • Despite overall growth, there have been challenges, such as financial constraints that caused a substantial drop in patient transports between 2017 and 2019, though services resumed with improvements in 2022.
  • While NAS has achieved a level of geographic equity, utilization rates vary across regions, particularly in lower-income areas where access to services remains a challenge.

Increasing the involvement of laypersons in prehospital first aid can be an important part of the response to injuries and other medical emergencies. We sought to understand factors associated with the willingness of laypersons in Ghana to provide first aid to road traffic crash victims.

Concentrations of C-reactive protein (CRP) and procalcitonin (PCT) have been suggested as markers of infection. The liver is believed to be a key source of CRP and PCT. For this reason we assessed the predictive value of these markers in patients with hepatic cirrhosis in a 31-bed university-hospital department of intensive care.
