RESUMO
OBJECTIVE: Spinal fusion surgery is known to be an expensive intervention. Although innovative technologies in the field aim at improving operative efficiency and outcomes, total costs must be considered. The authors hope to elucidate any differences between robot-assisted (RA) and computed tomography navigation (CT-nav) or freehand fluoroscopy-guided (FFG) pedicle screw placement in relation to patient outcomes and cost-effectiveness in lumbar fusion surgery (LFS). METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the authors performed a systematic review to identify studies comparing clinical outcomes between CT-nav or RA versus FFG in LFS patients. All included studies utilized bilateral pedicle screws. Statistical analysis was performed using R. RESULTS: Of the 1162 identified studies, 5 were included in the analysis. Direct evidence showed that RA decreased hospital length of stay when compared to FFG (mean difference [MD]: -2.67 days; 95% confidence interval [CI]: -4.25 to -1.08; P < 0.01). Indirect evidence showed that RA decreased operative time when compared to CT-nav (MD: -65.57 minutes; 95% CI: -127.7 to -3.44; P < 0.05). For estimated blood loss, direct evidence showed that RA was superior to FFG (MD: -120.62 mL; 95% CI: -206.39 to -34.86; P < 0.01). However, no significant difference was found between RA and CT-nav for estimated blood loss (MD: 14.88 mL; 95% CI: -105.54 to 135.3; P > 0.05). There were no other significant differences in Oswestry Disability Index, visual analog scale, or complication or reoperation rates between RA and FFG or CT-nav. CONCLUSIONS: This study shows that RA pedicle screw placement in LFS provides similar patient outcomes to CT-nav and FFG. Robot-assisted operations were found to give rise to cost savings via decreased length of stay when compared to both CT-nav and FFG techniques. Cost-savings of $4086-$4865/patient and $7317-$9654/patient could be achieved when utilizing RA over CT-nav and FFG, respectively. However, extra upfront and maintenance costs may impact full adoption of RA in LFS.
RESUMO
Background: The United States is currently experiencing an unprecedented rise in fatal drug overdoses, which is in part due to the arrival of fentanyl, fentanyl analogs, and other synthetic drugs into the illicit drug supply. Traditional urine drug testing is often unable to detect fentanyl analogs and other novel synthetic drugs, which places physicians and first responders in the difficult position of treating patients who are intoxicated with or overdosing on unknown substances. Design and methods: We report, as a feasibility study, the development of a novel program to use a handheld Raman spectrometry device in our hospital's Emergency Department to surveil our local illicit drug supply in terms of what substances are being sold and used. Results: Using our novel program, we were able to detect 27 substances in our illicit drug supply over a 10 month period, including fentanyl analogues. We shared, through our local opioid safety coalition, real-time information to first responders, substance use treatment programs, and physicians about the novel substances we detected using the handheld Raman spectrometer. Conclusions: A community partnership of using handheld Raman spectrometry in our hospital's Emergency Department was successful in providing information to health care providers about novel substances in our illicit drug market. Additionally, the implementation of this program improved collaboration between local health care providers and local law enforcement.
