Preoperative evaluation: Impact on early perioperative hemodynamic and respiratory complications

BACKGROUND

The impact of routine preoperative anesthesia evaluations on potential perioperative complications remains unclear. This study aimed to investigate the effect of preoperative evaluation on early perioperative hemodynamic and respiratory complications.

METHODS

This prospective observational study analyzed data from patients aged 18 to 80 who underwent elective surgery between October 15, 2023, and February 15, 2024. The study evaluated the effect of preoperative anesthesia evaluation on hemodynamic and respiratory complications occurring during surgery and within the first 24 h postoperatively, as well as its impact on the length of hospital stay.

RESULTS

The analysis included 1117 patients for whom complete data was available. Hemodynamic and respiratory complications were observed in 545 patients (48.7%), occurring within the first 24 h intraoperatively and postoperatively. Because no additional examinations beyond routine blood tests, radiological imaging, and electrocardiograms were performed in the preoperative period, the impact of these tests on the development of hemodynamic and respiratory complications could not be determined. There was no statistically significant association between the presence or absence of preoperative consultation and the occurrence of early perioperative hemodynamic and respiratory complications [OR (95% CI): 0.879 (0.646-1.195); P = 0.411], nor did it affect the length of hospital stay [median (IQR); 2 (3) vs. 2 (3); P = 0.245].

CONCLUSION

While the impact of routinely requested laboratory and imaging methods before surgery could not be assessed in this study, consultations that were requested did not affect hemodynamic and respiratory complications in the early perioperative period or on the duration of hospital stay.

TRIAL REGISTRATION NUMBER

Samsun University Samsun Training and Research Hospital, following ethics committee approval (Samsun University clinical research ethics committee (KAEK) 2.12.2023) and Clinical Trials (NCT06203171 / 04.18.2024) registration.

Using patient feedback to predict effects of quality improvement initiatives

BACKGROUND

Internationally, continuous efforts have been put into developing patient complaint channels to understand patients' experience and expectation of care, which can guide the improvement of health service quality. Despite agreement among the value of patient feedback, limited attention has been paid to using patient feedback to predict and promote the actual quality improvement initiatives.

OBJECTIVE

To determine whether patient feedback collected from a public feedback hotline can be used to predict the effect of hospital quality service improvement initiatives.

METHODS

A retrospective analysis of patient complaint data of a tertiary hospital from 2018 to 2021 was performed. Patient complaints were first coded by the standard classification method of the Australian Hospital Patient Experience Question Set. The characteristics of patients' complaints were then analysed by frequency and contingency table analysis. Finally, through Nonparametric Mann-Kendall test and Joinpoint regression model, the trends of each complaint characteristics were tested.

RESULTS

Amongst the 771 complaints received against clinicians, approximately 75% of them were concerning doctors. 'Harm and distress' was the key reason of complaints, followed by 'not cared for', 'lack of confidence', 'needs unmet' and 'not informed'. In 2021, the number of complaints received in relation to moderate 'harm and distress' caused by doctors increased by 667% from 2020. The categories of 'not informed', 'not cared for' and 'harm and distress' were also on the rise with statistical significance. In addition, complaints related to the lack of respect, bad attitude and unprofessional behaviour demonstrated by nurses (n = 83) and doctors (n = 121) were also recorded.

CONCLUSION

Patient feedbacks collected via a public feedback hotline provides a useful platform to gain insight into patient experience of care which are valuable to guide quality care improvement. To improve the care quality, clinicians need to participate in quality improvement strategies development at an early stage. Efforts in improving communication and interaction between doctors and patients are needed to improve patients' experience of care and developing patients' trust in both of the clinicians and the medical services. The study highlights the value of using public feedback hotline to generate evidence that can guide hospital service improvement.

Evaluation of the Geriatric Trauma Outcome Score (GTOS) as a Prognostic Tool in Intensive Care Unit Trauma Patients

BACKGROUND

Existing prognostic scoring systems for intensive care unit (ICU) trauma patients require extensive data collection. The Geriatric Trauma Outcome Score (GTOS), which is based on age, injury severity, and transfusion need, has been validated for predicting mortality in elderly patients with trauma; however, its utility in the general ICU trauma population remains unexplored.

METHODS

This retrospective study included 2952 adult ICU trauma patients admitted between 2016 and 2021. The GTOS was calculated as follows: age + (Injury Severity Score × 2.5) + 22 (if transfused within 24 h). The area under the receiver operating characteristic curve (AUROC) was used to assess GTOS's ability to predict mortality. The optimal GTOS cutoff was determined using Youden's index. Mortality rates were compared between the high and low GTOS groups, including a propensity score-matched analysis adjusted for baseline characteristics.

RESULTS

This study included 2952 ICU trauma patients, with an overall mortality rate of 11.0% (n = 325). GTOS demonstrated good predictive accuracy for mortality (AUROC 0.80). The optimal cutoff was 121.8 (sensitivity, 0.791; specificity, 0.685). Despite adjustments, patients with GTOS ≥ 121.8 had significantly higher mortality (17.4% vs. 6.2%, p < 0.001) and longer hospital stays (20.3 vs. 15.3 days, p < 0.001) compared to GTOS < 121.8.

CONCLUSIONS

GTOS showed a reasonable ability to predict mortality in ICU trauma patients across all ages, although not as accurately as more complex ICU-specific models. With its simplicity, the GTOS may serve as a rapid screening tool for risk stratification in acute ICU trauma settings when combined with other data.

Design and Implementation of an Intensive Care Unit Command Center for Medical Data Fusion

The rapid advancements in Artificial Intelligence of Things (AIoT) are pivotal for the healthcare sector, especially as the world approaches an aging society which will be reached by 2050. This paper presents an innovative AIoT-enabled data fusion system implemented at the CMUH Respiratory Intensive Care Unit (RICU) to address the high incidence of medical errors in ICUs, which are among the top three causes of mortality in healthcare facilities. ICU patients are particularly vulnerable to medical errors due to the complexity of their conditions and the critical nature of their care. We introduce a four-layer AIoT architecture designed to manage and deliver both real-time and non-real-time medical data within the CMUH-RICU. Our system demonstrates the capability to handle 22 TB of medical data annually with an average delay of 1.72 ms and a bandwidth of 65.66 Mbps. Additionally, we ensure the uninterrupted operation of the CMUH-RICU with a three-node streaming cluster (called Kafka), provided a failed node is repaired within 9 h, assuming a one-year node lifespan. A case study is presented where the AI application of acute respiratory distress syndrome (ARDS), leveraging our AIoT data fusion approach, significantly improved the medical diagnosis rate from 52.2% to 93.3% and reduced mortality from 56.5% to 39.5%. The results underscore the potential of AIoT in enhancing patient outcomes and operational efficiency in the ICU setting.

Personalized Noninvasive Respiratory Support in the Perioperative Setting: State of the Art and Future Perspectives

Background: Noninvasive respiratory support (NRS), including high-flow nasal oxygen therapy (HFNOT), noninvasive ventilation (NIV) and continuous positive airway pressure (CPAP), are routinely used in the perioperative period. Objectives: This narrative review provides an overview on the perioperative use of NRS. Preoperative, intraoperative, and postoperative respiratory support is discussed, along with potential future areas of research. Results: During induction of anesthesia, in selected patients at high risk of difficult intubation, NIV is associated with improved gas exchange and reduced risk of postoperative respiratory complications. HFNOT demonstrated an improvement in oxygenation. Evidence on the intraoperative use of NRS is limited. Compared with conventional oxygenation, HFNOT is associated with a reduced risk of hypoxemia during procedural sedation, and recent data indicate a possible role for HFNOT for intraoperative apneic oxygenation in specific surgical contexts. After extubation, "preemptive" NIV and HFNOT in unselected cohorts do not affect clinical outcome. Postoperative "curative" NIV in high-risk patients and among those exhibiting signs of respiratory failure can reduce reintubation rate, especially after abdominal surgery. Data on postoperative "curative" HFNOT are limited. Conclusions: There is increasing evidence on the perioperative use of NRS. Use of NRS should be tailored based on the patient's specific characteristics and type of surgery, aimed at a personalized cost-effective approach.

Effect of implementing an anesthesia nurse checklist in a safety and teamwork climate: quasi-experimental study

OBJECTIVE

To evaluate the effect of implementing a Patient safety checklist: nursing in anesthetic procedure on the perception of safety climate and team climate of nurses and anesthesiologists from an operating room.

METHOD

Quasi-experimental study held in the operating room of a hospital in Brazil with a sample of nurses and anesthesiologists. The outcome was evaluated through the instruments "Safety Attitudes Questionnaire/Operating Room Version" and "Team Climate Inventory", applied before and after the implementation of a Patient safety checklist: nursing in anesthetic procedure by nurses. The mixed effects linear regression model was used to analyse the effect of the implementation.

RESULTS

Altogether, 19 (30.2%) nurses and 44 (69.8%) anesthesiologists participated in the study, implementing the Patient safety checklist: nursing in anesthetic procedure in 282 anesthesias. The Safety Attitudes Questionnaire/Operating Room Version score changed from 62.5 to 69.2, with modification among anesthesiologists in the domain "Perception of management" (p = 0.02). Between both professionals, the Team Climate Inventory score increased after the intervention (p = 0.01).

CONCLUSION

The implementation of the Patient safety checklist: nursing in anesthetic procedure changed the perception score of safety and teamwork climate, improving communication and collaborative work.

The Impact of Establishing a Dedicated Liver Surgery Program at a University-affiliated Hospital on Workforce, Workload, Surgical Outcomes, and Trainee Surgical Autonomy and Academic Output

Objective

To detail the implementation of a dedicated liver surgery program at a university-affiliated hospital and to analyze its impact on the community, workforce, workload, complexity of cases, the short-term outcomes, and residents and young faculties progression toward technical autonomy and academic production.

Background

Due to the increased burden of liver tumors worldwide, there is an increased need for liver centers to better serve the community and facilitate the education of trainees in this field.

Methods

The implementation of the program is described. The 3 domains of workload, research, and teaching were compared between 2-year periods before and after the implementation of the new program. The severity of disease, complexity of procedures, and subsequent morbidity and mortality were compared.

Results

Compared with the 2-year period before the implementation of the new program, the number of liver resections increased by 36% within 2 years. The number of highly complex resections, the number of liver resections performed by residents and young faculties, and the number of publications increased 5.5-, 40-, and 6-fold, respectively. This was achieved by operating on more severe patients and performing more complex procedures, at the cost of a significant increase in morbidity but not mortality. Nevertheless, operations during the second period did not emerge as an independent predictor of severe morbidity.

Conclusions

A new liver surgery program can fill the gap between the demand for and supply of liver surgeries, benefiting the community and the development of the next generation of liver surgeons.

Is Organizational Communication Climate a Precondition for Patient-Centered Care? Insights from a Key Informant Survey of Various Health and Social Care Organizations

Health and social care organizations are under pressure of organizing care around patients' needs and preferences while complying with regulatory frameworks and constraint resources. To implement patient-centered care in health and social care organizations successfully, particular organizational preconditions need to be considered. Findings on the implementation of patient-centered care and its preconditions are rare and insufficiently account for the organizational context to explain differences. This study examines the implementation status of patient-centered care in diverse health and social care organizations and analyzes the communication climate as a precondition of successful implementation. In a cross-sectional postal key informant survey, decision makers in the highest leading positions from six different types of health and social care organizations in Cologne, Germany, were surveyed using a paper-pencil questionnaire. Patient-centered care implementation was operationalized by three categories (principles, activities, and enablers) including 15 dimensions. Organizational communication climate was operationalized by aspects of open and constructive communication, cooperation, and inclusion. Out of 1790 contacted organizations, 237 participated. In the analyses, 215 complete datasets were included. Descriptive analyses, Kruskal-Wallis test, post hoc pair-wise test, and linear regression modeling were performed. Results show that the implementation status of patient-centered care was perceived as high but differed between the various types of organizations and in terms of patient-centered care categories. Organizational communication climate was significantly associated with the implementation of patient-centered care. Especially in organizations with a higher number of employees, strategies to create a positive communication climate are needed to create a precondition for patient-centered care.

Current Status of Neurosurgical and Neurointensive Care Units in Korea : A Brief Report on Nationwide Survey Results

Objective

The purpose of this study is identify the operation status of the neurosurgical care units (NCUs) in neurosurgical residency training hospitals nationwide and determine needed changes by comparing findings with those obtained from the Korean Neurosurgical Society (KNS) and Korean Society of Neurointensive Care Medicine (KNIC) survey of 2010.

Method

This survey was conducted over 1 year in 86 neurosurgical residency training hospitals and two neurosurgery specialist hospitals and focused on the following areas : 1) the current status of the infrastructure and operating systems of NCUs in Korea, 2) barriers to installing neurointensivist team systems, 3) future roles of the KNS and KNIC, and 4) a handbook for physicians and practitioners in NCUs. We compared and analyzed the results of this survey with those from a KNIC survey of 2010.

Results

Seventy seven hospitals (87.5%) participated in the survey. Nineteen hospitals (24.7%) employed a neurointensivist or faculty member; Thirty seven hospitals (48.1%) reported high demand for neurointensivists, and 62 hospitals (80.5%) stated that the mandatory deployment of a neurointensivist improved the quality of patient care. Forty four hospitals (57.1%) believed that hiring neurointensivist would increase hospital costs, and in response to a question on potential earnings declines. In terms of potential solutions to these problems, 70 respondents (90.9%) maintained that additional fees were necessary for neurointensivists’ work, and 64 (83.1%) answered that direct support was needed of the personnel expenses for neurointensivists.

Conclusion

We hope the results of this survey will guide successful implementation of neurointensivist systems across Korea.

Death in low-risk cardiac surgery revisited

Background

A systematic review of low-risk death has been shown successful in identifying system weaknesses. The aim was to analyse early mortality in low-risk patients undergoing cardiac surgery and to determine the cause of death, classify if they were unavoidable or potentially preventable as a result of technical or system errors.

Methods

We included all low-risk patients who underwent cardiac surgery at our institution from 1 September 2009 to 31 August 2019. In patients operated between 2009 and 2011, we defined low risk as an additive European System for Cardiac Operative Risk Evaluation (EuroSCORE) I less than or equal to 3, and from 2012 and onwards as a EuroSCORE II less than or equal to 1.5. The medical records for the patients who died within 30 days of surgery were thoroughly examined and the cause of death was classified as cardiac or non-cardiac. Furthermore, deaths were categorised as not preventable, preventable (technical error) or preventable (system error).

Results

During the study period 3103 low-risk patients underwent surgery, and 11 patients died within 30 days of the operation (0.35%). Six of these (55%) were classified as preventable and five non-preventable. Four of the preventable deaths were classified as technical errors and two were due to system errors.

Conclusions

A repeated systematic review of deaths in patients with a low preoperative risk showed that a majority of deaths were preventable, and therefore potentially avoidable. Similar to the previous assessment at our unit, mortality was very low and failure to communicate remains a modifiable factor that should be addressed.
