Analysis of High Infection Risk Percutaneous Injuries in Taiwan Health Care Workers
To identify the area, mechanism, device and its original purpose of use in high infection risk percutaneous injuries (PIs) in different type of health care workers (HCWs) in Taiwan. Further, to estimate the risk to seroconvert HBV, HCV and HIV after having a high infection risk PI.
Data from Chinease EPINet between Janunary 2004 and March 2013 wer analyzed to identify the frequency and comparsion of proportions for location, mechanism, device and its orginal purpose of use in high infection risk PIs. The statistical package JMP 10.0. was. Incidence rate was calculated by using the number of the full-time equivalent healthcare workers in the hosptials which contributed the high infection risk PIs. Estimation of seroconversion after high infection PIs was also performed.
The hosptial which had high infection risk PIs rate was “Metropolitan Hospital”(53.3%), and “nurse”(63.7%) accounted for the most high infection risk PIs. The locationwhere high infection risk PIs occurred most frequently was “patient rooms”(34.6%). The mechanism which caused high infection risk PIs most frequently were “between steps of a multi-step procedure” (24.6%). The most commonly seen device caused high infection risk PIs was “disposable(?) syringes”(39.3%).The original purpose of use of the device were”injection, followed by IM/subcutaneous and other”(20.0%).
There are disparities of high infection risk PIs in different job categories and at different health care settings. “Delivery rooms”, “dialysis units”, “intensive care units”, and “patient rooms” were areas where the most High infection risk PIs occurred.
The incidence rate of high infection risk PIs is 0.77/100 FTEs in all HCWs. After adjusting the reporting rate, the estimation of HBV seroconversion is 90~227 persons annually, 383~934 persons for HCV seroconversion, and 1-56 persons for HIV seroconversion.
The most common device caused high infection risk PIs was syringe needles. This study conluded that “dialysis rooms”, “intensive care units”,”patient rooms”and “blood collection centers” had the highest chance for high infection risk PIs. This study intends to increase the safety awareness of the HCWs in medical devices use, and to urge hospital to replace all medical devices to the ones with safety features if the 2011 National Needlestick Safety and Prevention Act and health care workers’ occupational safety are warranted.
