From Open to MIS: Robotic Surgery Enables Surgeons to Do More With Less

Hospital costs of robotic-assisted and open treatment of large ventral hernias

Robotic-assisted treatment of ventral hernia offers many advantages, however, studies reported higher costs for robotic surgery compared to other surgical techniques. We aimed at comparing hospital costs in patients undergoing large ventral hernia repair with either robotic or open surgery. We searched from a prospectively maintained database patients who underwent robotic or open surgery for the treatment of the large ventral hernias from January 2016 to December 2022. The primary endpoint was to assess costs in both groups. For eligible patients, data was extracted and analyzed using a propensity score-matching. Sixty-seven patients were retrieved from our database. Thirty-four underwent robotic-assisted surgery and 33 open surgery. Mean age was 66.4 ± 4.1 years, 50% of patients were male. After a propensity score-matching, a similar total cost of EUR 18,297 ± 8,435 vs. 18,024 ± 7514 (p = 0.913) in robotic-assisted and open surgery groups was noted. Direct and indirect costs were similar in both groups. Robotic surgery showed higher operatory theatre-related costs (EUR 7532 ± 2,091 vs. 3351 ± 1872, p < 0.001), which were compensated by shorter hospital stay-related costs (EUR 4265 ± 4366 vs. 7373 ± 4698, p = 0.032). In the treatment of large ventral hernia, robotic surgery had higher operatory theatre-related costs, however, they were fully compensated by shorter hospital stays and resulting in similar total costs.

Analysis of Factors Associated with Same-Day Discharge After Robotic Transversus Abdominis Release for Incisional Hernia Repairs

Background: Advancement in surgery has shifted numerous procedures to a same-day discharge (SDD) setting. In this study, we evaluated factors related to SDD after robotic transversus abdominis release (rTAR). Materials and Methods: A retrospective analysis of a prospectively maintained hernia databank was performed. Patients who underwent rTAR for incisional hernias were assigned to either the SDD group (length of stay [LOS] <1) or the inpatient group (LOS ≥1 day). Pre-, intra-, and postoperative variables were compared. Predictors of SDD were explored through a logistic regression, and a mediation analysis was performed to assess their effect on the LOS. Results: Out of the 167 patients included, 53 patients were discharged the same day. Age, American Society of Anesthesiologists score, history of coronary artery disease, and wound infection were significantly higher in the inpatient group. Overall, median LOS was 1 (0-2). Postoperative complications did not differ between SDD and inpatient groups except for Clavien-Dindo Grade-II (1 versus 14, respectively; P = .039). Thirty-day readmission rates were comparable (P = .229). A binary logistic regression to predict factors associated with SDD rTAR showed statistical significance in age, operative time, mesh area, and history of wound infection. Mediation analysis showed that mesh size indirectly affected the LOS through the operative time (a = 0.54; b = 0.46; P < .001). An age >46-year-old, an operative time beyond 217 minutes, and a mesh size >475 cm² increased the probability of an inpatient stay (area-under-the-receiver operating characteristic curves: 0.69, 0.81, and 0.82, respectively). Conclusion: The pre- and intraoperative factors associated with SDD rTAR were age, history of wound infection, operative time, and mesh area. Further studies are needed to investigate the appropriateness of discharge decisions while balancing patients' benefits, resource utilization, and costs.

Characterizing exposure to physical risk factors during veterinary surgery with wearable sensors: a pilot study

Occupational ApplicationsVeterinarians provide comprehensive health services for animals, but despite exposure to similar occupational and safety hazards as medical physicians, physical risk factors for these doctors and healthcare teams have not been characterized. In this pilot study, we used wearable sensor technology and showed that veterinary surgeons commonly experience static and demanding postures while performing soft tissue and orthopedic surgeries. Observations showed that muscle activation was highest in the right trapezius. Job factors such as surgical role (attending vs. assisting) and surgical specialty (soft tissue vs. orthopedics) appeared to influence exposure to physical risk factors. These findings suggest a need to consider the unique demands of surgical specialties in order to address the key risk factors impacting injury risks among veterinarians. For example, static postures may be a priority for soft tissue surgeons, while tools that reduce force requirements are more pressing for orthopedic surgeons.Technical AbstractBackground: Although musculoskeletal fatigue, pain, and injuries are commonly reported among surgeons in veterinary medicine, few studies have objectively characterized the exposure to physical risk factors among veterinary surgeons.Purpose: This study aimed to characterize muscle activation and postures of the neck and shoulders during live veterinary surgeries in the soft tissue and orthopedic specialties.Methods: Forty-four ergonomic exposure assessments (exposures) were collected during 26 surgical procedures across five surgeons. Exposures were collected from both soft tissue (n = 23) and orthopedic (n = 21) specialties. Physical risk factors were characterized by: 1) directly measuring muscle activation and posture of the neck and shoulders, using surface electromyography and inertial measurement units, respectively; and 2) collecting self-reported workload, pain, and stiffness.Results: Across the 44 exposures, neck and back symptoms respectively worsened after the surgery in 27% and 14% of the exposures. Veterinary surgeons exhibited neck postures involving a mean of 17° flexion during the surgical procedures. Static postures were common, occurring during 53-80% of the procedures. Compared to soft tissue procedures (e.g., 13.2% MVC in the right trapezius), higher muscle activity was observed during orthopaedic procedures (e.g., 27.6% MVC in the right trapezius).Conclusions: This pilot study showed that physical risk factors (i.e., muscle activity and posture of the neck/shoulder) can be measured using wearable sensors during live veterinary surgeries. The observed risk factors were similar to those documented for medical physicians. Further studies are needed to bring awareness to opportunities for improving workplace ergonomics in veterinary medicine and surgery.

Data Analytics in Smart Healthcare: The Recent Developments and Beyond

The concepts of the smart city and the Internet of Things (IoT) have been facilitating the rollout of medical devices and systems to capture valuable information of humanity. A lot of artificial intelligence techniques have been demonstrated to be effective in smart city applications like energy, transportation, retail and control. In recent decade, retardation of the adoption of data analytics algorithms and systems in healthcare has been decreasing, and there is tremendous growth in data analytics research on healthcare data. The results of analytics aim at improving people’s quality of life as well as relieving the issue of medical shortages. In this special issue “Data Analytics in Smart Healthcare”, thirteen (13) papers have been published as the representative examples of recent developments. Guest Editors also highlight some emergent topics and opening challenges in healthcare analytics which follow the visions of the movement of healthcare analytics research.
