Project description:IntroductionThe environmental impact of endoscopy is a topic of growing interest. This study aimed to compare the carbon footprint of performing an esogastroduodenoscopy (EGD) with a reusable (RU) or with a single-use (SU) disposable gastroscope.MethodsSU (Ambu aScope Gastro) and RU gastroscopes (Olympus, H190) were evaluated using life cycle assessment methodology (ISO 14040) including the manufacture, distribution, usage, reprocessing and disposal of the endoscope. Data were obtained from Edouard Herriot Hospital (Lyon, France) from April 2023 to February 2024. Primary outcome was the carbon footprint (measured in Kg CO2 equivalent) for both gastroscopes per examination. Secondary outcomes included other environmental impacts. A sensitivity analysis was performed to examine the impact of varying scenarios.ResultsCarbon footprint of SU and RU gastroscopes were 10.9 kg CO2 eq and 4.7 kg CO2 eq, respectively. The difference in carbon footprint equals one conventional car drive of 28 km or 6 days of CO2 emission of an average European household. Based on environmentally-extended input-output life cycle assessment, the estimated per-use carbon footprint of the endoscope stack and washer was 0.18 kg CO2 eq in SU strategy versus 0.56 kg CO2 eq in RU strategy. According to secondary outcomes, fossil eq depletion was 130 MJ (SU) and 60.9 MJ (RU) and water depletion for 6.2 m3 (SU) and 9.5 m3 (RU), respectively.ConclusionFor one examination, SU gastroscope have a 2.5 times higher carbon footprint than RU ones. These data will help with the logistics and planning of an endoscopic service in relation to other economic and environmental factors.
Project description:BackgroundFlexible rhinolaryngoscopes are an important tool in otolaryngology. In recent years, single-use rhinolaryngoscopes (SURLs), which have been developed as an alternative to reusable scopes (RRLs), offer various advantages including less risk of contamination and elimination of the need for cleaning and reprocessing between procedures. This study aimed to compare procedure efficiency, organizational impact, and economic impact between SURLs and RRLs used for elective procedures conducted outside the otorhinolaryngology department in the hospital environment.MethodsIn this randomized prospective study, either type of endoscope was tested by on-call otolaryngologists over a total of twelve weeks. The organizational impact was investigated using a quantitative research design. All categories of stakeholders responded to specific surveys based on profession; these included doctors (n = 13), those in managerial positions (n = 3), and other healthcare staff including technicians and nurses (n = 11). A micro-costing approach was used to evaluate resource utilization and cost of services. The trial was uploaded to clinicaltrials.gov (ID number: NCT0519821, https://clinicaltrials.gov/study/NCT05198219?intr=rhinolaryngo&rank=1).ResultsOverall, 14 and 12 procedures were performed using the SURLs and RRLs, respectively. No significant differences were observed between the endoscopes in terms of procedure duration, reported image quality, or maneuverability. The SURLs were significantly superior in terms of four organizational impact parameters, namely, modes of cooperation and communication, vigilance and monitoring methods, working conditions and safety, and logistics. The estimated per-procedure cost of the RRLs was SEK 536 (€ 34,68).ConclusionThe cost and effectiveness of RRLs and SURLs is influenced by the healthcare setting, procedure volume, and duration of device use. The adoption of SURLs can improve safety, streamline processes, and potentially reduce the risk of disease transmission.
Project description:BackgroundGeographic cohorting is a hospital admission structure in which every patient on a given physician team is admitted to a dedicated hospital unit. Little is known about the long-term impact of this admission structure on patient outcomes and resident satisfaction.ObjectiveTo evaluate the effect of geographic cohorting on patient outcomes and resident satisfaction among inpatient internal medicine teaching services within an academic hospital.Design and interventionWe conducted an interrupted time series analysis examining patient outcomes before and after the transition to geographic cohorting of our 3 inpatient teaching services within a 520-bed academic hospital in November 2017. The study observation period spanned from January 2017 to October 2018, allowing for a 2-month run-in period (November-December 2017).ParticipantsWe included patients discharged from the inpatient teaching teams during the study period. We excluded patients admitted to the ICU and observation admissions.Main measuresPrimary outcome was 6-month mortality adjusted for patient age, sex, race, insurance status, and Charlson Comorbidity Index (CCI) analyzed using a linear mixed effects model. Secondary outcomes included hospital length of stay (LOS), 7-day and 30-day readmission rate, Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores, and resident evaluations of the rotation.Key resultsDuring the observation period, 1720 patients (mean age 64, 53% female, 56% white, 62% Medicare-insured, mean CCI 1.57) were eligible for inclusion in the final adjusted model. We did not detect a significant change in 6-month mortality, LOS, and 7-day or 30-day readmission rates. HCAHPS scores remained unchanged (77 to 80% top box, P = 0.19), while resident evaluations of the rotation significantly improved (mean overall score 3.7 to 4.0, P = 0.03).ConclusionsGeographic cohorting was associated with increased resident satisfaction while achieving comparable patient outcomes to those of traditional hospital admitting models.
Project description:BackgroundBoth single-use and reusable bronchoscopes are suitable for percutaneous dilatational tracheostomy (PDT) to visualise the trachea during the insertion process. To determine the least costly option, the price of single-use bronchoscopes must be weighed against the estimated average cost of a bronchoscopy with reusable equipment. In the latter case, the acquisition cost must be spread over the equipment's useful life and other relevant costs, such as reprocessing and repair, must be included.ObjectiveThis study aimed to calculate the cost of using single-use or reusable bronchoscopes per PDT procedure.MethodsA systematic literature search was conducted to identify studies comparing the costs of reusable and single-use bronchoscopes for PDT. Inclusion criteria were articles assessing the cost of single-use or reusable bronchoscopes, and where costs were divided into acquisition, reprocessing, and repair costs. A questionnaire regarding repair rates and costs for reusable bronchoscopes was sent to 366 hospitals in the US, UK, and Germany to supplement the identified literature.ResultsEleven studies met the inclusion criteria. Ninety-nine completed responses were received, of which 31 hospitals used reusable equipment for PDT. Literature research revealed an average acquisition cost of $US135 (SD 152) and reprocessing cost of $US123 (SD 128). Additionally, a combination of data from the literature and the questionnaires gave a repair cost per use of $US148 (SD 242), resulting in a total average cost of $US406 for reusable bronchoscopes and $US249 (SD 36) for single-use bronchoscopes per PDT procedure. Thus, the incremental cost per use of a reusable bronchoscope compared with a single-use bronchoscope was $US157.ConclusionsWe conclude that significant savings can be made by using single-use bronchoscopes to guide PDT in preference to reusable bronchoscopes. Results depend on hospital setting, the reprocessing procedures, annual bronchoscope procedures, individual repair cost, and repair rates.
Project description:BackgroundHybrid surgical instruments contain both single-use and reusable components, potentially bringing together advantages from both approaches. The environmental and financial costs of such instruments have not previously been evaluated.MethodsWe used Life Cycle Assessment to evaluate the environmental impact of hybrid laparoscopic clip appliers, scissors, and ports used for a laparoscopic cholecystectomy, comparing these with single-use equivalents. We modelled this using SimaPro and ReCiPe midpoint and endpoint methods to determine 18 midpoint environmental impacts including the carbon footprint, and three aggregated endpoint impacts. We also conducted life cycle cost analysis of products, taking into account unit cost, decontamination, and disposal costs.ResultsThe environmental impact of using hybrid instruments for a laparoscopic cholecystectomy was lower than single-use equivalents across 17 midpoint environmental impacts, with mean average reductions of 60%. The carbon footprint of using hybrid versions of all three instruments was around one-quarter of single-use equivalents (1756 g vs 7194 g CO2e per operation) and saved an estimated 1.13 e-5 DALYs (disability adjusted life years, 74% reduction), 2.37 e-8 species.year (loss of local species per year, 76% reduction), and US $ 0.6 in impact on resource depletion (78% reduction). Scenario modelling indicated that environmental performance of hybrid instruments was better even if there was low number of reuses of instruments, decontamination with separate packaging of certain instruments, decontamination using fossil-fuel-rich energy sources, or changing carbon intensity of instrument transportation. Total financial cost of using a combination of hybrid laparoscopic instruments was less than half that of single-use equivalents (GBP £131 vs £282).ConclusionAdoption of hybrid laparoscopic instruments could play an important role in meeting carbon reduction targets for surgery and also save money.
Project description:BackgroundApart from conventional reusable bronchoscopes, single-use bronchoscopes (SUB) were recently introduced. Data suggest that SUB might prevent from the risk of cross contamination (i.e. multiresistant pathogens, SARS CoV-2) and save costs. We aimed to investigate visualization, ventilation, handling characteristics, changes in patients' gas exchange, and costs associated with both types of bronchoscopes during percutaneous dilatational tracheostomy (PDT).MethodsIn this prospective, randomized, noninferiority study, 46 patients undergoing PDT were randomized 1:1 to PDT with SUB (Ambu aScope) or reusable bronchoscopes (CONV, Olympus BF-P60). Visualization of tracheal structures rated on 4-point Likert scales was the primary end-point. Furthermore, quality of ventilation, device handling characteristics, changes in the patients' gas exchange, pH values, and costs were assessed.ResultsNoninferiority for visualization (the primary endpoint) was demonstrated for the SUB group. Mean visualization scores (lower values better) were 4.1 (95% confidence intervals: 3.9;4.3) for SUB vs. 4.1 (4.0;4.2) for CONV. Noninferiority of ventilation (estimated by minute volume and SpO2) during the procedure could be shown as well. Mean score was 2.6 (2.0;3.1) for SUB vs. 2.4 (2.1;2.7) for CONV (lower values better). No significant differences regarding handling (SUB: 1.2 (1.0;1.4), CONV: 1.3 (1.1;1.6)), blood gas analyses and respiratory variables were found. Cost analysis in our institution revealed 93 € per conventional bronchoscopy versus 232.50 € with SUB, not considering an estimate for possible infection due to cross-contamination with the reusable device.ConclusionIn our study, visualization and overall performance of the SUB during PDT were noninferior to reusable bronchoscopes. Therefore, PDT with SUB is feasible and should be considered if favored by individual institution's cost analysis.Trial registrationClinicalTrials.gov, NCT03952247 .

Project description:PurposeTo provide insight into the types of questions asked to medical physicists by patients during one-on-one physicist-patient consults at one institution.Materials and methodsMedical physicists trained in patient communication techniques met with patients to provide an overview of the treatment planning and delivery processes, discuss the patient's treatment plan, and answer any technical questions. From August 2016 to December 2019, 152 physicist-patient consults were conducted. In the initial months of the study (August 2016-December 2017), following each physicist-patient consult, all patient questions were documented by the physicists. For the remaining time period (January 2018-December 2019), any newly encountered questions were periodically added to the list. The questions were compiled into a comprehensive list and organized into categories.ResultsThere were a total of 88 unique patient questions. These questions fit into four topical categories. Fifty-four questions (61.4%) were in the "Treatment Planning and Delivery Questions" category, 15 questions (17.1%) were in the "General Radiation Questions or Concerns" category, 13 questions (14.8%) were in the "Safety and Quality Assurance Questions" category, and 6 questions (6.8%) were in the "Medical Questions" category. Overall, patients were primarily concerned about how radiation works, the treatment planning and delivery processes, and what is being done to keep them safe throughout their treatment.ConclusionPhysicist-patient consults provided an opportunity to address the technical aspects of radiation therapy with patients in greater detail. The fact that patient questions could be conveniently grouped into only four topical categories indicates that it may be straightforward for other medical physicists to prepare for effectively addressing technical questions during physicist-patient consults.
Project description:BackgroundCommunication and courtesy are important elements of consultations, but there is limited published data about the quality of trainee consults.ObjectivesThis study assessed residents' views on consult interactions, evaluated the impact of the consult interactions on patient care, and developed and implemented a pocket card and training on trainee consults.MethodsWe surveyed resident and fellow physicians at Mount Sinai Hospital to assess perceptions, created a CONSULT card that uses a mnemonic for key elements, and developed a training session for how to call consults. We also conducted a consult training session using the CONSULT card as part of orientation in 2011 for all interns. We assessed the acceptability, feasibility, and sustainability of this intervention.ResultsOf 1001 trainees, 403 (40%) responded. Respondents reported that the most important components of calling consults included giving patient name, medical record number, and location (91%), and giving a clear question/reason (89%). Respondents also reported that these behaviors are done consistently for only 64%, and 10% of consults, respectively. Trainees reported that consult interactions affect the timeliness of treatment (62%), timeliness of tests performed (57%), appropriateness of diagnosis (56%), and discharge planning (49%). Approximately 300 interns attended the consult training session, and their feedback demonstrated acceptability and utility of the session.ConclusionsTrainees believe that consult interactions impact patient care, but important components of the consult call are often missing. Our training and CONSULT card is an acceptable, feasible, and novel training intervention. Once developed, the training session and CONSULT card require minimal faculty time to deliver.
Project description:PurposeThere is limited literature available regards the frequency and characteristics of COVID-19 + ve status among advanced cancer patients referred to an inpatient supportive care consultation(PC) at a tertiary cancer center. Our study aimed to determine the frequency and characteristics of COVID-19 + ve cancer patients seen by PC.MethodsAdvanced cancer patients seen as a consult by PC between June 15 and September 25, 2020, at MD Anderson Cancer Center were eligible for the study. We evaluated the patient demographics, clinical characteristics including symptoms(ESAS), delirium(MDAS), COVID + status prior to, and after PC referral(converters), and type of PC delivery(in person or virtual care).ResultsSixty-six out of 1380 (4.8%) PC consults were COVID-19 + ve: 42 prior to PC (79%), and 14 (21%) were COVID-19 + ve after the PC (converters). COVID-19 + PC patients had lower depression (P = .035), spiritual distress (P = .003), and were more seen frequently virtually (P < 0.001). There was no significant difference between COVID-19-ve patients and converters. Converters had higher symptom distress (P = 0.007), lower delirium (P = 0.014), and were referred earlier (P = .011) compared to COVID + PC patients diagnosed prior to PC consult. Overall, patients seen virtually compared in-person by PC were younger (P = 0.02) and had lower delirium (P = 0.007).ConclusionThe burden of COVID-19 + status among patients referred to PC was low. COVID-19 + ve patients had more frequent virtual visits, lower depression, and spiritual distress scores. Patient seen virtually were significantly younger and had lower delirium. During a new pandemic, universal virtual care might be emphasized especially at initial encounters after admission and further research is needed on the potential efficacy of this intervention.
