Background: Road safety authorities in high-income countries use geospatial motor vehicle collision data for planning hazard reduction and intervention targeting. However, low-income and middle-income countries (LMICs) rarely conduct such geospatial analyses due to a lack of data. Since 1991, Ghana has maintained a database of all collisions and is uniquely positioned to lead data-informed road injury prevention and control initiatives.

- Road traffic injuries and fatalities have declined globally, but significant variations exist in low- and middle-income countries like Ghana, which has unique spatial data on motor vehicle collisions (MVCs).
- An analysis of 16 years of police data using ArcGIS reveals that while minor injuries are decreasing, severe injuries and deaths remain unchanged, highlighting the need for focused road safety efforts.
- The study identifies persistent hot spots on urban and rural roads in Ghana where injury severity is high, emphasizing the necessity for targeted interventions in those areas and providing a replicable approach for other countries.
Road traffic collisions disproportionately impact Ghana and other low- and middle-income countries. This study explored road user perspectives regarding the magnitude, contributing factors, and potential solutions to road traffic collisions, injuries, and deaths. We designed a qualitative study of 24 in-depth interviews with 14 vulnerable road users (pedestrians, occupants of powered 2- and 3-wheelers, cyclists) and ten non-vulnerable road users in four high-risk areas in November 2022.

- Chronic thrombocytopenia (CT) significantly affects patients undergoing chronic total occlusion (CTO) percutaneous coronary interventions (PCI), leading to worse health outcomes and higher hospital costs.
- The study analyzed discharge data from 2016-2018 and found that patients with CT had a 4.8% higher chance of extended hospital stays and incurred about $18,000 more in hospital charges compared to those without CT.
- In conclusion, the presence of chronic thrombocytopenia in CTO PCI patients is linked to increased healthcare resource use and poorer in-hospital results.
