Background: This study aimed to obtain an answer for the question: Are ergonomic guidelines applied in the operating room and what are the consequences? Methods: A total of 1,292 questionnaires were sent by email or handed out to surgeons and residents. The subjects worked mainly in Europe, performing laparoscopic and/or thoracoscopic procedures within the digestive, thoracic, urologic, gynecologic, and pediatric disciplines. Results: In response, 22% of the questionnaires were returned. Overall, the respondents reported discomfort in the neck, shoulders, and back (almost 80%). There was not one specific cause for the physical discomfort. In addition, 89% of the 284 respondents were unaware of ergonomic guidelines, although 100% stated that they find ergonomics important. Conclusion:The lack of ergonomic guidelines awareness is a major problem that poses a tough position for ergonomics in the operating room.
ObjectiveTo assess surgical team members’ differences in perception of non-technical skills.DesignQuestionnaire design.SettingOperating theatres (OTs) at one university hospital, three teaching hospitals and one general hospital in the Netherlands.ParticipantsSixty-six surgeons, 97 OT nurses, 18 anaesthetists and 40 nurse anaesthetists.MethodsAll surgical team members, of five hospitals, were asked to complete a questionnaire and state their opinion on the current state of communication, teamwork and situation awareness at the OT.ResultsRatings for ‘communication’ were significantly different, particularly between surgeons and all other team members (P ≤ 0.001). The ratings for ‘teamwork’ differed significantly between all team members (P ≤ 0.005). Within ‘situation awareness’ significant differences were mainly observed for ‘gathering information’ between surgeons and other team members (P < 0.001). Finally, 72–90% of anaesthetists, OT nurses and nurse anaesthetists rated routine team briefings and debriefings as inadequate.ConclusionsThis study shows discrepancies on many aspects in perception between surgeons and other surgical team members concerning communication, teamwork and situation awareness. Future research needs to ascertain whether these discrepancies are linked to greater risk of adverse events or to process as well as systems failures. Establishing this link would support implementation and use of complex team interventions that intervene at multiple levels of the healthcare system.
Operative notes do not adequately represent the actual LCs performed as they describe fewer important procedural steps. It is suggested that operative notes should include video recordings.
Shortages of medical equipment in low-and-middle income countries (LMICs) have been found by several previous studies that assessed surgical capacity. To increase surgical capacity, there is a need to identify the availability of specific types of surgical equipment on a local, regional and national level. A survey was conducted among surgeons attending the annual meeting of the College Of Surgeons of East, Central and Southern Africa (COSECSA) in December 2016. General information of the facilities, availability of surgical equipment, reasons for limited availability, daily usage of equipment and equipment that could benefit from redesign were assessed. Forty-two respondents participated in this study, representing 33 individual healthcare facilities (14 public referrals, 9 public district and 10 private (for-profit and non-profit)). The respondents worked in 9 countries in East, Central, Western and Southern Africa. A deficiency in availability of basic surgical equipment was found, especially in public district hospitals. Electrosurgical units, endoscopes, defibrillators, infusions pumps and electrocardiogram monitors were of limited availability. Reasons indicated for this limited availability were: no need, too costly, no training, no disposables and no repair. Lack of maintenance and old/overused equipment were identified as major reasons for failure of equipment. Equipment that could benefit from redesign were for example: electrosurgical units, laparoscopic equipment and theatre lights. Availability of surgical equipment should be increased, especially in public district hospitals. Novel context appropriate redesign that is adapted to fit the context in LMICs could decrease the barriers to availability and to failure of surgical equipment.
Information technology, such as real-time location (RTL) systems using Radio Frequency IDentification (RFID) may contribute to overcome patient safety issues and high costs in healthcare. The aim of this work is to study if a RFID specific Participatory Design (PD) approach supports the design and the implementation of RTL systems in the Operating Room (OR). A RFID specific PD approach was used to design and implement two RFID based modules. The Device Module monitors the safety status of OR devices and the Patient Module tracks the patients' locations during their hospital stay. The PD principles 'multidisciplinary team', 'participation users (active involvement)' and 'early adopters' were used to include users from the RFID company, the university and the hospital. The design and implementation process consisted of two 'structured cycles' ('iterations'). The effectiveness of this approach was assessed by the acceptance in terms of level of use, continuity of the project and purchase. The Device Module included eight strategic and twelve tactical actions and the Patient Module included six strategic and twelve tactical actions. Both modules are now used on a daily basis and are purchased by the hospitals for continued use. The RFID specific PD approach was effective in guiding and supporting the design and implementation process of RFID technology in the OR. The multidisciplinary teams and their active participation provided insights in the social and the organizational context of the hospitals making it possible to better fit the technology to the hospitals' (future) needs.
Background Iatrogenic bile duct injury remains a current complication of laparoscopic cholecystectomy. One uniform and standardized protocol, based on the ''critical view of safety'' concept of Strasberg, should reduce the incidence of this complication. Furthermore, owing to the rapid development of minimally invasive surgery, technicians are becoming more frequently involved. To improve communication between the operating team and technicians, standardized actions should also be defined. The aim of this study was to compare existing protocols for laparoscopic cholecystectomy from various Dutch hospitals.Methods Fifteen Dutch hospitals were contacted for evaluation of their protocols for laparoscopic cholecystectomy. All evaluated protocols were divided into six steps and were compared accordingly.Results In total, 13 hospitals responded-5 academic hospitals, 5 teaching hospitals, 3 community hospitals-of which 10 protocols were usable for comparison. Concerning the trocar positions, only minor differences were found.
The importance of measuring intra-abdominal pressure (IAP) has increased since the negative effects of sustained increased IAP, also known as intra-abdominal hypertension (IAH), have become known. The relation between IAP and abdominal wall tension has been included in several reports. We have developed a device to measure abdominal wall tension by measuring force and distance. This device enables us to investigate the correlation between the abdominal wall tension and IAP. The abdomens of two corpses (one female, one male) were insufflated with air. IAP was increased and measured at intervals by means of a laparoscopic set-up. Abdominal tension was measured at seven points on the abdominal wall at each interval. Pearson's correlation coefficients were used to determine the relationship between IAP and tension for each point measured. ANOVA was used to assess relations between measured tensions versus applied pressure, locations and subjects. In both corpses, all points showed significant (p < 0.001) correlations between IAP and abdominal wall tension. The points along the mid transverse plane appear to be more similar compared to more cranial and caudal points. We have assessed the feasibility of a device that non-invasively can track changes in IAP. Measurements performed with the device are preliminary results, and further investigation is needed.
Three-dimensional (3D) printing may be a solution to shortages of equipment and spare parts in the healthcare sector of low-and middle-income countries (LMICs). Polylactic acid (PLA) for 3D printing is widely available and biocompatible, but there is a gap in knowledge concerning its compatibility with chemical disinfectants. In this study, 3Dprinted PLA tensile samples were created with six different printer settings. Each of these six batches consisted of five sets with five or six samples. The first set remained untreated, the others were soaked in Cidex OPA or in a chlorine solution. These were applied for seven consecutive days or in 25 short cycles. All samples were weighed before and after treatment and subjected to a tensile test. Results showed that a third of the treatments led to an increase of the median weight with a maximum of 8.3%, however, the samples with the best surface quality did not change. The median strength increase was 12.5% and the largest decrease was 8.8%. The median stiffness decreased 3.6% in one set and increased in three others up to 13.6%. When 3D printing PLA medical tools, surface porosity must be minimized to prevent transfer of disinfectants to people. The wide variability of mechanical properties due to 3D printing itself and as a consequence of disinfection must be considered when designing medical tools by selecting appropriate printer settings. If these conditions are met, reusing 3D-printed PLA medical tools seems safe from a mechanical point of view.
