Early impact analysis of remote vital sign monitoring after esophagectomy: a multi-method study design
Background: Esophagectomy is associated with serious postoperative complications in 20-40% of the patients. Early recognition and treatment of these complications is critical to prevent secondary damage. To support medical professionals in the timely detection of clinical deterioration in patients admitted to the ward, it is of interest to use wireless sensor technologies allowing unobtrusive continuous vital sign tracking. However, it is yet unclear under which circumstances and to what extent telemonitoring provides beneficial effects in this patient population. Methods: We designed a multi-methods and multicenter study to evaluate the expected effects of continuous vital sign monitoring in the postoperative ward trajectory of patients undergoing esophagectomy. Semi-structured interviews with nurses and surgeons are conducted to elicit the probability of earlier detection and treatment of postoperative complications and the effects on related clinical outcome measures (mortality, ICU readmissions, and hospital stay length). To support valid estimations, interviews include scenarioβs incorporating the characteristics and outcomes from center-specific patient population. Decision tree analysis is performed to assess the relation between clinical outcome for current situation and the conceived situation with continuous ward monitoring. Findings: We expect that the proposed study will provide insight in the clinical effects of continuous remote vital sign monitoring in the postoperative ward in patients undergoing esophagectomy. Discussion: Decision tree analysis combined with expert elicitation enables assessment of the afferent (i.e. monitoring) and efferent (i.e. response chain) arm of telemonitoring, and facilitates impact analysis in an early stage. The results of this study can be used to optimize the strategy of vital sign monitoring in wards, and to target situations where improvement in patient outcome and safety is expected

The value of improving patient safety: Health-economic considerations for Rapid Response Systems β a Rapid Review of the Literature and Expert Round Table
Objectives Failure to rescue deteriorating patients in hospital is a well-researched topic. We aimed to explore the impact of safer care on health economic considerations for clinicians, providers and policymakers.Design We undertook a rapid review of the available literature and convened a round table of international specialists in the field including experts on health economics and value-based healthcare to better understand health economics of clinical deterioration and impact of systems to reduce failure to rescue.Results Only a limited number of publications have examined the health economic impact of failure to rescue. Literature examining this topic lacked detail and we identified no publications on long-term cost outside the hospital following a deterioration event. The recent pandemic has added limited literature on prevention of deterioration in the patientsβ home.Cost-effectiveness and cost-efficiency are dependent on broader system effects of adverse events. We suggest including the care needs beyond the hospital and loss of income of patients and/or their informal carers as well as sickness of healthcare staff exposed to serious adverse events in the analysis of adverse events. They are likely to have a larger health economic impact than the direct attributable cost of the hospital admission of the patient suffering the adverse event. Premorbid status of a patient is a major confounder for health economic considerations.Conclusion In order to optimise health at the population level, we must limit long-term effects of adverse events through improvement of our ability to rapidly recognise and respond to acute illness and worsening chronic illness both in the home and the hospital
Introduction of a Post-Anaesthesia Care Unit in a Teaching Hospital Is Associated with a Reduced Length of Hospital Stay in Noncardiac Surgery:A Single-Centre Interrupted Time Series Analysis
Background: A post-anaesthesia care unit (PACU) may improve postoperative care compared with intermediate care units (IMCU) due to its dedication to operative care and an individualized duration of postoperative stay. The effects of transition from IMCU to PACU for postoperative care following intermediate to high-risk noncardiac surgery on length of hospital stay, intensive care unit (ICU) utilization, and postoperative complications were investigated. Methods: This single-centre interrupted time series analysis included patients undergoing eleven different noncardiac surgical procedures associated with frequent postoperative admissions to an IMCU or PACU between January 2018 and March 2019 (IMCU episode) and between October 2019 and December 2020 (PACU episode). Primary outcome was hospital length of stay, secondary outcomes included postoperative complications and ICU admissions. Results: In total, 3300 patients were included. The hospital length of stay was lower following PACU admission compared to IMCU admission (IMCU 7.2 days [4.2β12.0] vs. PACU 6.0 days [3.6β9.1]; p < 0.001). Segmented regression analysis demonstrated that the introduction of the PACU was associated with a decrease in hospital length of stay (GMR 0.77 [95% CI 0.66β0.91]; p = 0.002). No differences between episodes were detected in the number of postoperative complications or postoperative ICU admissions. Conclusions: The introduction of a PACU for postoperative care of patients undergoing intermediate to high-risk noncardiac surgery was associated with a reduction in the length of stay at the hospital, without increasing postoperative complications.</p
Wireless Remote Home Monitoring of Vital Signs in Patients Discharged Early After Esophagectomy:Observational Feasibility Study
Non-invasive bladder volume measurement for the prevention of postoperative urinary retention:validation of two ultrasound devices in a clinical setting
Ultrasound scanning of bladder volume is used for prevention of postoperative urinary retention (POUR). Accurate assessment of bladder volume is needed to allow clinical decision-making regarding the need for postoperative catheterization. Two commonly used ultrasound devices, the BladderScan (R) BVI 9400 and the newly released Prime (R) (Verathon Medical (R), Bothell, WA, USA), with or without the pre-scan' option, have not been validated in clinical practice. The aim of this study was to assess the performance of these devices in daily clinical practice. Between June and September 2016 a prospective observational study was conducted in 318 surgical patients (18years or older) who needed a urinary catheter perioperatively for clinical reasons. For acceptable performance, we required that the volume as estimated by the BladderScan (R) differs by no more than 5% from the actual urine volume after catheterization. The Schuirmann's two one-sided test was performed to assess equivalence between the BladderScan (R) estimate and catheterization. The BVI 9400 (R) overestimated the actual bladder volume by +17.5% (95% CI +8.8 to +26.3%). The Prime (R) without pre-scan underestimated by -4.1% (95% CI -8.8 to +0.5%) and the Prime (R) with pre-scan underestimated by -6.3% (95% CI -11.6 to -1.1%). This study shows that while both ultrasound devices were able to approximate current bladder volume, both BVI 9400 (R) and Prime (R) with and without pre-scanwere not able to measure the actual bladder volume within our predefined limit of +/- 5%. Using the pre-scan feature of the Prime (R) did not further improve accuracy
