Epidemiology of Needle Stick Injuries at a Tertiary Care Hospital in Trinidad From 2011 to 2016: A Retrospective Study.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe most significant infections via needle-stick injuries (NSIs) involve hepatitis B, hepatitis C, and HIV, and the most common device is a hollow-bore needle or suture needle. This study aimed to determine the epidemiology and associated factors that contribute to occupational exposures to blood and bodily fluids at a hospital in South Trinidad and Tobago.
methodsThis study was conducted retrospectively from 2011 to 2016 in one tertiary public health institution in Trinidad and Tobago. Data were extracted from incident reports, occupational health records, and infection prevention and control (IPC) unit documentation. Primary outcomes included demographic characteristics, occupation, and departmental distribution of NSIs. Secondary outcomes assessed the circumstances of injury, anatomical site, glove use, laboratory investigations, and administration of post‑exposure prophylaxis (PEP).
resultsA total of 221 healthcare workers reported NSIs, with a mean age of 34.97 years. Most affected individuals were women and clinical staff. "Other" (e.g., psychiatry, or in transit outside wards/units) accounted for the highest proportions of injuries, followed by internal medicine, while the IPC unit received the majority of first reports. Procedures were the most common activity associated with injury, followed by discarding needles and recapping. Fingers were the most frequently affected sites, particularly the right index and left ring fingers. Documentation gaps were notable, especially regarding glove use and time to reporting. PEP was administered in most cases, and official reporting to the IPC unit was associated with a higher likelihood of receiving PEP. Laboratory testing commonly included renal and liver function tests, complete blood counts, and screening for blood‑borne pathogens.
conclusionNSIs reflect ongoing challenges in occupational safety. Strengthening IPC training, improving reporting practices, promoting safer sharps handling, and implementing safety‑engineered devices are essential to reducing NSI incidence and improving post‑exposure management.
