Environmental sustainability and gynaecological surgery: Which factors influence behaviour? An interview study.

OBJECTIVE: To assess the various factors that influence environmentally sustainable behaviour in gynaecological surgery and examine the differences between gynaecologists and residents. DESIGN: An interview study. SETTING: Academic and non-academic hospitals in the Netherlands. POPULATION: Gynaecologists (n = 10) and residents (n = 6). METHODS: Thematic analysis of semi-structured interviews to determine the various factors that influence environmentally sustainable behaviour in gynaecological surgery and to examine the differences between gynaecologists and residents. By using the Desmond framework and the COM-B BCW, both organisational and individual factors related to behaviour were considered. MAIN OUTCOME MEASURES: Factors that influence environmentally sustainable behaviour. RESULTS: Awareness is increasing but practical knowledge is insufficient. It is crucial to integrate education on the environmental impact of everyday decisions for residents and gynaecologists. Gynaecologists make their own choices but residents' autonomy is limited. There is the necessity to provide environmentally sustainable surgical equipment without compromising other standards. There is a need for a societal change that encourages safe and open communication about environmental sustainability. To transition to environmentally sustainable practices, leadership, time, collaboration with the industry and supportive regulatory changes are essential. CONCLUSION: This study lays the groundwork for promoting more environmentally sustainable behaviour in gynaecological surgery. The key recommendations, addressing hospital regulations, leadership, policy revisions, collaboration with the industry, guideline development and education, offer practical steps towards a more sustainable healthcare system. Encouraging environmentally sustainable practices should be embraced to enhance the well-being of both our planet and our population, driving us closer to a more environmentally sustainable future in healthcare.

User experience of wearing comfort of reusable versus disposable surgical gowns and environmental perspectives: A cross-sectional survey.

OBJECTIVE: To determine the user experience of wearing comfort of reusable sterile surgical gowns and compare these gowns with conventional disposable surgical gowns. DESIGN: Cross-sectional survey. SETTING: An academic hospital in the Netherlands. POPULATION: Gynaecologists, surgeons, residents and operating room assistants (n=80). METHODS: Quantitative and qualitative data were obtained via a written questionnaire. Participants provided subjective comments and scored the reusable gown on each individual topic with a score from 1 to 5 (1 = unsatisfactory, 2 = moderate, 3 = good, 4 = very good, 5 = excellent) and compared the reusable gown with the conventional disposable alternative (better, equal or worse). MAIN OUTCOME MEASURES: Wearing comfort: ventilation and temperature regulation, fit and length, functionality, barrier function and ease of use. RESULTS: The results of the overall scores of the reusable gown are scored as 'very good' (mean 4.3, SD ± 0.5) by its users. Regarding comparison of the gowns, more than 79% (lowest score 79%, highest score 95%) of the participants scored the reusable gown equal or higher on six of seven topics. The topic 'ease of use' was scored equal or higher by 59% of the participants. Subjective comments provided information on possible improvements. CONCLUSIONS: The findings of this study demonstrate that there is professional acceptance regarding the utilisation of reusable surgical gowns. To facilitate broader adoption, it is imperative to foster collaboration among suppliers and healthcare institutions. The reusable surgical gown is an environmentally sustainable, safe and comfortable alternative in the operating room.

Operating Room Performance Optimization Metrics: a Systematic Review.

Literature proposes numerous initiatives for optimization of the Operating Room (OR). Despite multiple suggested strategies for the optimization of workflow on the OR, its patients and (medical) staff, no uniform description of 'optimization' has been adopted. This makes it difficult to evaluate the proposed optimization strategies. In particular, the metrics used to quantify OR performance are diverse so that assessing the impact of suggested approaches is complex or even impossible. To secure a higher implementation success rate of optimisation strategies in practice we believe OR optimisation and its quantification should be further investigated. We aim to provide an inventory of the metrics and methods used to optimise the OR by the means of a structured literature study. We observe that several aspects of OR performance are unaddressed in literature, and no studies account for possible interactions between metrics of quality and efficiency. We conclude that a systems approach is needed to align metrics across different elements of OR performance, and that the wellbeing of healthcare professionals is underrepresented in current optimisation approaches.

Towards spill-free in-bag morcellation: a health failure mode and effects analysis.

BACKGROUND: To assess potential risks of new surgical procedures and devices before their introduction into daily practice, a prospective risk inventory (PRI) is a required step. This study assesses the applicability of the Health Failure Mode and Effects Analysis (HFMEA) as part of a PRI of new technology in minimally invasive gynecologic surgery. METHODS: A reference case was defined of a patient with presumed benign leiomyoma undergoing a laparoscopic hysterectomy or myomectomy including in-bag power morcellation; however, pathology defined a stage I uterine leiomyosarcoma. Using in-bag morcellation as a template, a HFMEA was performed. All steps of the in-bag morcellation technique were identified. Next, the possible hazards of these steps were explored and possible measures to control these hazards were discussed. RESULTS: Five main steps of the morcellation process were identified. For retrieval bags without openings to accommodate instruments inside the bag, 120 risks were identified. Of these risks, 67 should be eliminated. For containment bags with openings 131 risks were identified of which 68 should be eliminated. Of the 10 causes most at risk to cause spillage, two can be eliminated by using appropriate bag materials. Myomectomy appears to be more at risk for residual tissue spillage compared to total hysterectomy. CONCLUSION: The HFMEA has provided important new insights regarding potential weaknesses of the in-bag morcellation technique, particularly with respect to hazardous steps in the morcellation process as well as requirements that bags should meet. As such, this study has shown HFMEA to be a valuable method that identifies and quantifies potential hazards of new technology.

Where are my instruments? Hazards in delivery of surgical instruments.

BACKGROUND: Unavailability of instruments is recognised to cause delays and stress in the operating room, which can lead to additional risks for the patients. The aim was to provide an overview of the hazards in the entire delivery process of surgical instruments and to provide insight into how Information Technology (IT) could support this process in terms of information availability and exchange. METHODS: The process of delivery was described according to the Healthcare Failure Mode and Effects Analysis methodology for two hospitals. The different means of information exchange and availability were listed. Then, hazards were identified and further analysed for each step of the process. RESULTS: For the first hospital, 172 hazards were identified, and 23 of hazards were classified as high risk. Only one hazard was considered as 'controlled' (when actions were taken to remove the hazard later in the process). Twenty-two hazards were 'tolerated' (when no actions were taken, and it was therefore accepted that adverse events may occur). For the second hospital, 158 hazards were identified, and 49 of hazards were classified as high risk. Eight hazards were 'controlled' and 41 were 'tolerated'. The means for information exchange and information systems were numerous for both cases, while there was not one system that provided an overview of all relevant information. CONCLUSIONS: The majority of the high-risk hazards are expected to be controlled by the use of IT support. Centralised information and information availability for different parties reduce risks related to unavailability of instruments in the operating room.

Resuscitation of preterm infants with different inspired oxygen fractions.

OBJECTIVE: To test the hypothesis that an initial fraction of inspired oxygen (FiO2) of 30% during resuscitation of preterm infants results in less oxidative stress and is associated with improved clinical outcomes compared with an FiO2 of 65%. STUDY DESIGN: Preterm infants of gestational age <32 weeks (n = 193) were randomized to start resuscitation with either 30% oxygen (low-oxygen group) or 65% oxygen (high-oxygen group), after which the FiO2 was adjusted based on oxygen saturation values. The primary outcome was bronchopulmonary dysplasia (BPD) assessed at 36 weeks postmenstrual age. Secondary outcomes included major neonatal illnesses and markers of oxidative stress. RESULTS: The median gestational age of included infants was 28(6)/7 weeks (IQR, 26(5)/7-30(3)/7 weeks). The incidence of BPD was not significantly different between the low-oxygen and high-oxygen groups (24% vs. 17%; P = .15). The FiO2 in both groups was adjusted to a mean of 40% by 7 minutes in the low-oxygen group and by 11 minutes in the high-oxygen group. No differences in markers of oxidative stress were noted between groups. CONCLUSION: Initial supplementation of preterm infants with 30% oxygen during the fetal-to-neonatal transition is as safe as 65% oxygen, with no differences in oxidative stress markers or BPD.

A literature review on flow-rate variability in neonatal IV therapy.

AIM: To provide an overview of factors influencing the flow rate in intravenous (IV) therapy for newborns. METHODS: We conducted a review of the literature from 1980 to 2011 in PubMed and Web of Knowledge. Articles focusing on flow-rate variability and possible complications due to flow-rate variability were included. RESULTS: Forty-one articles were selected for this review. IV therapy in (preterm) neonates is prone to significant start-up delays and flow-rate variability. The sudden changes in the volume delivered to (preterm) neonates may have serious consequences. Low preprogrammed flow rates, total compliance, and volume of the IV administration set, the presence or absence of antisiphon valves or inline filters and the vertical displacement of syringe pumps all contribute to flow-rate variability in IV therapy for neonates. CONCLUSIONS: Flow-rate variability in IV therapy and its clinical relevance are due to the preprogrammed flow rate, the hydrostatic pressure changes, the complete IV administration set compliance and the type of substances supplied to the patient. To improve IV therapy, the internal compliance of the complete IV administration set should be minimized and the highest possible preprogrammed flow rate should be used in combination with small syringes and low-resistance valves.

"New-generation" pulse oximeters in extremely low-birth-weight infants: how do they perform in clinical practice?

The aim of this study was to evaluate the performance of "new-generation" pulse oximeters in extremely low-birth-weight ([ELBW] ≤ 1000 g) infants. In a prospective crossover observational study, the performance of pulse oximeters of 3 brands (Masimo, Nellcor, and Philips) was evaluated by dual SpO2 measurement in ELBW infants. Disposable probes of either equal or different brands were placed around both feet of the patient simultaneously for approximately 4 hours. Probes were switched between feet every hour. Absolute differences in SpO2 values (ΔSpO2) and the bias between brands were studied. Nine ELWB infants were included (gestational age: mean ± SD = 26(3)/7 ± 1 4/7 weeks). The median (range) ΔSpO2 was 2% (0%-26%). In 9% of the time, ΔSpO2 was 5% or more. The variance of the difference of the 3 pulse oximeter brands was not significantly different. No consequent bias between brands was found. Simultaneously obtained pulse oximeter measurements from the feet of ELBW infants differ from each other. Our results suggest that it is not the brand but the handling of the pulse oximeter in clinical practice, such as the place and positioning of the probe, that influences the performance of the pulse oximeter the most. Improvement in the accuracy of oxygen-monitoring techniques for ELBW infants is required.

[Steps for reducing the carbon footprint of the operating room]. / Manieren om de CO2-voetafdruk van de OK te verlagen.

The healthcare sector contributes significantly to global warming due to carbon emissions; this sector is, therefore, partially responsible for the negative effects of climate change on public health. Carbon emissions by the healthcare sector amount to 7% of the total carbon footprint of the Netherlands. It is anticipated that measures to reduce carbon emissions in the operating room (OR) can make an important contribution to reducing carbonemissions in the hospital as a whole. The most important elements contributing to the carbon footprint of the OR are: energy consumption for heating, ventilation and air conditioning (HVAC); the emission of inhalation anaesthetics; the purchase of materials and equipment; and waste production. Direct carbon emissions by the OR can be reduced through the use of sustainable energy and setback of the HVAC outside office hours. Anaesthetists can dramatically reduce the carbon footprint of the OR by choosing for intravenous anaesthetics instead of inhalation anaesthetics. Indirect carbon emissions and waste production by the OR can be reduced through circular procurement, choosing reusable over disposable products and recycling.

Observing the resuscitation of very preterm infants: are we able to follow the oxygen saturation targets?

BACKGROUND: Since 2010, the European Resuscitation Council (ERC) guidelines advise oxygen saturation (SpO2) targets for the first 10 min of resuscitation after birth. Unfortunately, the control of SpO2 in newborn infants is difficult. AIM: To determine to what extent SpO2 levels match the ERC targets during the resuscitation of very preterm infants, and how well the SpO2 is kept within the high and low limits until the infants are transported to the NICU. METHODS: In a single-centre observational study, the SpO2 and fraction of inspired oxygen (FiO2) were collected during the resuscitation of very preterm infants with a gestational age (GA)≤ 30 weeks. RESULTS: A total of 78 infants were included [median (IQR): GA 27(4)/7 (26-28(6)/7) weeks, birth weight 945 g (780-1140)]. During the initial 10 min after birth, large variations in SpO2 were observed with deviations above the target [median (IQR)] of 4.4% SpO2 (1.4-6.5), and below the target of 8.2% SpO2 (2.8-16.0). After the first 10 min, the SpO2 levels were respectively above and below the limit for 11% (0-27) and 8% (0-23) of the time. CONCLUSION: During the resuscitation of very preterm infants, large deviations of the SpO2 from the ERC targets are observed. During the first minutes of resuscitation the deviations were likely caused by an inability to control the SpO2, whereas later deviations were due to weaning, pauses in respiratory support (i.e. intubation) and over exposure to oxygen. Changing the SpO2 targets to a target range that depicts the acceptable deviation might be helpful in providing better respiratory support.

Resuscitation of very preterm infants with 30% vs. 65% oxygen at birth: study protocol for a randomized controlled trial.

BACKGROUND: Resuscitation at birth with 100% oxygen is known to increase the oxidative burden with concomitant deleterious effects. Although fractions of inspired oxygen (FiO2) < 100% are widely used in preterm infants, starting resuscitation at a (too) low FiO2 may result in hypoxia. The objective of this study is to compare the safety and efficacy of resuscitating very preterm infants with an initial FiO2 of 30% versus 65%. METHODS/DESIGN: In this double-blind, randomized controlled trial, 200 very preterm infants with a gestational age < 32 weeks will be randomized to start resuscitation after birth with either 30% or 65% oxygen. The FiO2 will be adjusted based on oxygen saturation measured by pulse oximetry (SpO2) and pulse rate (which should be over 100 beats per minute) in order to achieve a target SpO2 of 88-94% at 10 min of life. The FiO2 and pulse oximetry data will be continuously recorded.The primary outcome is survival without bronchopulmonary dysplasia, as assessed by a physiological test at 36 weeks postmenstrual age. The secondary outcomes include the time to achieve SpO2 > 88%, Apgar score at 5 min, cumulative O2 exposure, oxidative stress (as determined by glutathione synthesis and oxidative stress markers), retinopathy of prematurity, brain injury and neurodevelopmental outcome at 2 years of age.This study will provide insight into determining the appropriate initial FiO2 to start resuscitation of very preterm infants.
