Background & Aim: Operating room personnel are always exposed to blood-borne infections because of Needlestick Injuries (NSIs). Thus, this study was conducted to determine the effectiveness of an educational intervention to promote NSIs preventive behaviors among the operating room personnel based on the health belief model (HBM).
Methods & Materials: This is an interventional study with a pre-test/post-test, control group design, conducted on 90 operating room personnel (45 personnel in each group) from four hospitals in Hamadan City in 2018. The participants completed a self-administered questionnaire including demographic and professional variables and HBM constructs. The intervention included four educational sessions held for the experimental group within one month. Both groups were followed up for three months after the intervention. Data were analyzed by the SPSS software version 18 using independent t-test, chi-square, Fisher exact test, and analysis of covariance (ANCOVA).
Results: The results showed that before the educational intervention, there was no statistically significant difference in the mean scores of HBM constructs between the experimental and control groups (P>0.05). However, after the educational intervention, both the experimental and control groups had a statistically significant difference between before and after changes in the mean scores of knowledge, perceived vulnerability, perceived benefits, perceived self-efficacy, and NSIs preventive behaviors (P<0.05).
Conclusion: According to the results, applying the educational intervention based on the HBM is an appropriate and effective approach in preventing NSIs among the operating room personnel.

Background & Aim: Back pain is highly prevalent among operating room technologists, and conventional treatments—such as non-steroidal anti-inflammatory drugs—are often associated with adverse long-term side effects. This study aims to evaluate the effect of Tuinatherapy massage with chamomile oil extract on the severity of back pain in female operating room technologists.
Methods & Materials: This double-blind, randomized controlled clinical trial included 105 female operating room technologists selected via convenience sampling from several hospitals in Isfahan. Participants were randomly assigned to three groups of 35 individuals each: (1) Tuinatherapy massage with liquid oil supplemented with chamomile oil extract, (2) Tuinatherapy massage with liquid oil alone, and (3) a control group receiving no intervention. The Tuinatherapy massage sessions consisted of 10 sessions, each lasting 20 minutes and conducted every other day. Pain intensity was measured using the Visual Analog Scale (VAS) both before and after the intervention. Data analysis was performed using SPSS version 27, using one-way ANOVA and Tukey’s post hoc tests.
Results: Significant reductions in pain intensity were observed in groups one and two following the intervention compared to baseline (P<0.001). The control group showed no significant change. Prior to the intervention, there were no significant differences in pain scores among the three groups (P=0.230); however, post-intervention, pain intensity in group one was significantly lower than that in groups two and three (P<0.001).
Conclusion: Tuinatherapy massage effectively reduces back pain severity among female operating room technologists. Moreover, the inclusion of chamomile oil extract enhances this therapeutic effect. As an alternative to pharmacologic treatments, Tuinatherapy massage with chamomile oil may serve as a method for alleviating back pain in this population.
