Background: Pocket hematoma is a common adverse event following the insertion of cardiovascular implantable electronic devices (CIEDs), but the risk of wound infections associated with a pocket hematoma is unclear.
Objectives: This integrative review aims to examine the relationship between pocket hematoma and risk of wound infection in a CIED population.
Methods: A comprehensive literature search for articles assessing the relationship between pocket hematoma and infection in four electronic databases was conducted in October 2018.
Results: After screening and full text review, 7 studies met inclusion criteria (combined sample = 8,177 patients). Most studies (6/7) reported a significant relationship between pocket hematoma and all types of infection (OR = 6.9-24.98; p < 0.05). The proportion of wound infection among all types of infections was 61.5 - 100%.
Conclusions: Pocket hematoma is a significant risk factor for all types of infection, with the most frequent type of infection being wound infection.
