The objective of the study, conducted in the general wards of Flinders Medical Center in South Australia, was to determine whether the risk of needlestick injuries from hypodermic needles could be reduced by the use of needle covers that are applied with a one-handed technique immediately after use of the needle. Baseline rates of needlestick injury were collected for a year prior to the use of needle covers, and incident cases of needlestick injury were collected after needle covers were introduced. The odds ratio, derived from pre- and post-intervention data, for injuries over which the use of needle covers could have had no influence, was used to show that the net effect of other influences on needlestick rates was not significant. The use of needle covers was associated with a significant reduction in needlestick injuries to nurses. The odds ratio for needlestick injury for nurse injuries that needle covers could not have prevented was 0.92. (95% CI 0.40-2.03). The odds ratio for needlestick injury for nurse injuries that needle covers could have prevented was 0.40 (95% CI 0.18-0.82). Although the odds of ratio for needlestick injury to cleaners was 0.19, the 95% exact confidence interval was 0.00-1.64.
这项在南澳大利亚弗林德斯医疗中心普通病房开展的研究，目的是确定在使用针头后立即采用单手技术套上针帽，是否能够降低皮下注射针头导致针刺伤的风险。在使用针帽前收集了一年的针刺伤基线发生率，并在引入针帽后收集针刺伤的发病案例。从干预前后的数据得出的比值比，用于那些针帽使用可能没有影响的损伤，以表明其他因素对针刺率的净影响并不显著。针帽的使用与护士针刺伤显著减少相关。针帽无法预防的护士针刺伤的比值比为0.92（95%可信区间0.40 - 2.03）。针帽可以预防的护士针刺伤的比值比为0.40（95%可信区间0.18 - 0.82）。虽然清洁工针刺伤的比值比为0.19，但95%精确置信区间为0.00 - 1.64。
