Knowledge and Attitudes Regarding Human Papillomavirus Among Active Duty Service Members at a Large Military Base.

OBJECTIVE: To assess gaps in human papillomavirus (HPV) knowledge and current attitudes toward HPV vaccination among active duty soldiers at Fort Bragg, NC, and to evaluate the impact of the instruction intervention on knowledge and attitudes regarding HPV vaccination. METHODS: A six-question assessment was administered to soldiers presenting for appointments through the Epidemiology and Disease Control (EDC) Clinic at Fort Bragg in January 2020. Questions included five multiple choice knowledge assessments and a Likert scale attitude question regarding HPV vaccination. The assessment was administered before and after a one-on-one educational intervention conducted by the EDC Clinic nursing staff. Pre- and post-assessments were matched using unique encounter numbers. RESULTS: A total of 139 matched pre- and post-education assessments were completed. Statistically significant changes in HPV knowledge were observed in test score and percent correct (P < .001). Additionally, for individuals reporting no prior HPV vaccination, attitudes toward receiving it increased from 4 (interquartile range 3-5) to 5 (4-5) following instructions (P < .001). This indicates a shift from moderately interested to very interested. CONCLUSIONS: Results among soldiers demonstrated a lack of knowledge regarding HPV infection, its long-term effects, and preventive measures available among this population of active duty members. Assessment results also illustrated education about HPV infection and vaccination positively impacts soldiers' knowledge and attitudes toward HPV vaccination.

Feasibility and sustainability of a nurse-led intervention to integrate HPV vaccination into medical processing for active-duty Soldiers.

To increase Soldiers' access to HPV vaccination, we evaluated the feasibility and sustainability of a nurse-led intervention to integrate HPV vaccination into medical processing procedures for Soldiers. We partnered with nursing staff to introduce HPV vaccine into existing vaccination services at a nurse-led clinic that serves Soldiers at Fort Bragg, North Carolina. In addition to stocking the vaccine, the intervention included training nursing staff (n = 11) strategies for recommending HPV vaccination for Soldiers ages 18-26. We conducted surveys of nursing staff to assess their perspectives on feasibility. Nursing staff tracked HPV vaccine uptake among Soldiers for 4 weeks post-training to assess adoption and again for 2 weeks at 4-month follow-up to assess sustainability. We assessed delivery cost as the cost of personnel time, vaccine doses, and other materials during the initial 4-week intervention period. Nursing staff agreed that recommending HPV vaccination fit in with medical processing procedures (mean = 4.6 of 5.0). Of the 516 Soldiers offered HPV vaccine in the 4 weeks following the training, 198 (38%) accepted and received the vaccine. Soldier ages 18-20 more often accepted HPV vaccination than older Soldier ages 21-26 (46% versus 32%, p < .01). Vaccine uptake was similar at follow-up, with 98 of 230 eligible Soldiers (43%) receiving HPV vaccine. The total delivery cost was $12,737, with an average cost per vaccine dose delivered of $64. Our findings suggest that training nursing staff to recommend and administer HPV vaccinations to Soldiers is feasible and warrants wider-scale testing as a strategy to protect soldiers from HPV-attributable cancers.

HPV vaccination is not required for US military service, and Soldiers' uptake is low. We trained nursing staff at a large military clinic to recommend HPV vaccine to Soldiers using a nursing education intervention to integrate HPV vaccination into routine care for active duty Soldiers. Our findings suggest that training nursing staff to recommend and administer HPV vaccines to Soldiers is feasible and low cost, and may warrant wider-scale testing as a strategy for increasing military readiness and protecting Soldiers from HPV-attributable cancers. Until guideline and policy changes are implemented and HPV vaccine is required for military service, use of education strategies is one path to increasing HPV vaccine coverage among Soldiers to ensure protection from HPV-related diseases.

Planning C2 pedicle screw placement with multiplanar reformatted cervical spine computed tomography.

OBJECT: Careful preoperative planning with thin-slice computed tomography (CT) scan is useful for hardware placement at C2. Prior studies have shown considerable variability in the proportion of C2 vertebrae considered safe for pedicle screw placement, depending on the imaging technique used. Our work sought to more carefully define that proportion using a refined imaging technique on a large number of submillimeter CT scans. MATERIALS AND METHODS: We reviewed 150 submillimeter cervical spine studies randomly selected from CT scans performed at a Level 1 trauma center. OsiriX™ image analysis software was used to propagate a 5-mm cylinder through the plane of the pedicle on paracoronal reformatted CT scans. Hounsfield unit attenuation was used to determine whether the cylinder violated the pedicle. Binomial data were generated to determine the proportion of pedicles that would allow safe screw placement. RESULTS: We analyzed 300 pedicles in 150 patients. Using a standard C2 pedicle starting point, 32% of pedicles were breached by the 5-mm diameter cylinder. When screw trajectory was adjusted by moving the cylinder to fit the pedicle isthmus, establishing an optimized starting point, only 14% of pedicles were breached. Average pedicle length was 27.3 mm for screws that would have crossed the isthmus versus 13.2 mm for screws that would have stopped short due to potential breach. CONCLUSIONS: Findings of the current work suggest that preoperative imaging analysis or navigation can be useful adjuncts when anatomical variants are present.
