Clinical pharmacist interventions in an intensive care unit reduces ICU mortality at a tertiary hospital in Dubai, United Arab Emirates

BackgroundDrug-related problems (DRPs) are prevalent in critical care settings and can be life-threatening. Involving clinical pharmacists (CP) within the critical care team is recommended to optimize therapy and improve patient survival. ObjectiveTo classify DRPs identified by a CP in the Intensive Care Unit (ICU) and to assess the impact of CP interventions accepted by physicians on the length of ICU stay and in-hospital survival. MethodsThis study was conducted prospectively at the Medical ICU of Rashid Hospital, a tertiary hospital in Dubai, over a 16-month period from September 2021 to December 2022. The study included patients admitted to ICU during the study period. CP interventions were documented, and DRPs were classified using the modified Pharmaceutical Care Network Europe V.9.1. ResultsDuring the study period, 1004 interventions were recommended for 200 patients. The majority of these interventions, 92% (n = 922), received physician acceptance, and 82% (n = 820) were fully implemented by the physician. In total, 1033 drug-related problems (DRPs) were identified, with a median of 3 DRPs per patient. The most common DRPs was drug selection (61%), followed by dose selection (22%). There were 337 DRPs related to antimicrobial agents. Interestingly, we noted that when we adjusted for patients' demographic data and the Glasgow Coma Scale severity score, patients who received >4 implemented interventions exhibited lower cumulative hazard of death within 90 days of their ICU stay in comparison to their counterparts (adjusted Hazard Ratio: 0.10, 95% CI of 0.02–0.41; P = 0.027). ConclusionThe study emphasizes the critical role of CP in the ICU, addressing DRPs, and enhancing overall patient care. Furthermore, it highlights the potential impact of pharmacist interventions in improving patient survival outcomes. This underscores the importance of implementing CP services in ICUs across the UAE.

Early and long-term outcomes following redo mitral valve surgery in patients with prior minimally invasive mitral valve surgery.

The frequency of minimally invasive mitral valve surgery (MVS) has steadily increased over the last decades and therefore surgeons are now encountering an increasing number of patients requiring mitral valve (MV) reoperations post-minimally invasive MVS. The aim of this study was to analyse the early postoperative outcomes and the long-term survival in patients who undergo reoperative MVS following previous minimally invasive surgery. Patients who underwent redo MVS following prior minimally invasive MVS between January 2002 and December 2021 were included in our analysis. Study data were prospectively collected and retrospectively analysed. The primary outcomes were 30-day mortality and long-term survival. Among the 187 included patients, 34 (18.2%) underwent repeat MV repair and 153 (81.8%) MV replacement. The median age was 66 years (interquartile range 56-74) and 80 (42.8%) patients were female. Redo MVS was performed through median sternotomy in 169 patients (90.4%). A total of 77 (41.2%) patients had additional concomitant procedures. The median intensive care unit stay was 1 day (1-5). The 30-day mortality was 6.4% (12/187). Estimated survival at 5 and 12 years was 61.8% and 38.3%, respectively. Preoperative stroke (hazard ratio 3.28, 95% confidence interval 1.37-7.85, P = 0.007) as well as infective endocarditis (hazard ratio 1.85; 95% confidence interval 1.09-3.11, P = 0.021) were independent predictors of long-term mortality. Redo MVS following prior minimally invasive MVS can be performed safely with low early perioperative mortality and acceptable long-term survival. Preoperative stroke, infective endocarditis and concomitant tricuspid valve surgery are independent predictors of long-term mortality.

Effects of acute phase intensive electrical muscle stimulation in COVID-19 patients requiring invasive mechanical ventilation: an observational case-control study

We investigated the effects of acute-phase intensive electrical muscle stimulation (EMS) on physical function in COVID-19 patients with respiratory failure requiring invasive mechanical ventilation (IMV) in the intensive care unit (ICU). Consecutive COVID-19 patients requiring IMV admitted to a university hospital ICU between January and April 2022 (EMS therapy group) or between March and September 2021 (age-matched historical control group) were included in this retrospective observational case–control study. EMS was applied to both upper and lower limb muscles for up to 2 weeks in the EMS therapy group. The study population consisted of 16 patients undergoing EMS therapy and 16 age-matched historical controls (median age, 71 years; 81.2% male). The mean period until initiation of EMS therapy after ICU admission was 3.2 ± 1.4 days. The EMS therapy group completed a mean of 6.2 ± 3.7 EMS sessions, and no adverse events occurred. There were no significant differences between the two groups in Medical Research Council sum score (51 vs. 53 points, respectively; P = 0.439) or ICU mobility scale at ICU discharge. Addition of upper and lower limb muscle EMS therapy to an early rehabilitation program did not result in improved physical function at ICU discharge in severe COVID-19 patients.

Misuse of the P Value: Using Quality Improvement Analyses to Identify Clinically Significant Improvements.

Quantitative research and quality improvement (QI) both seek to improve care provided to patients. However, clinicians often blur the lines between how to appropriately analyze data from these methodologies. Clinicians may inappropriately use statistical analyses for QI initiatives, rather than using run and statistical process control (SPC) charts to analyze improvements in outcomes. The purpose of this article was to address the analytic methods used for QI initiatives in the clinical setting in an effort to show clinicians how to identify meaningful improvements in clinical practice. In this article, we provide an example comparing the same evidence-based practice/QI initiative (chlorhexidine gluconate bathing in a medical intensive care unit) using a quasi-experimental pretest/posttest research design with statistical analyses completed with t tests with analyses using run and SPC charts to show the data trended over time. Using a pretest/posttest design, chlorhexidine gluconate bathing compliance improved from 63% to 65%, a nonsignificant change, P = .075. These same data plotted on run and SPC charts, however, show a shift and a trend, indicating clinically significant improvements per QI methodologies. The example in this article highlights the pitfall of relying only on statistical analyses and P values to determine the importance of a clinical project, and provides a practical example for how run or SPC charts can be used to identify improvements over time.

Transforming nursing assessment in acute hospitals: A cluster randomised controlled trial of an evidence-based nursing core assessment (the ENCORE trial)

BackgroundPatient safety is threatened when early signs of clinical deterioration are missed or not acted upon. This research began as a clinical-academic partnership established around a shared concern of nursing physical assessment practices on general wards and delayed recognition of clinical deterioration. The outcome was the development of a complex intervention facilitated at the ward level for proactive nursing surveillance. MethodsThe evidence-based nursing core assessment (ENCORE) trial was a pragmatic cluster-randomised controlled trial. We hypothesised that ward intervention would reduce the incidence of patient rescue events (medical emergency team activations) and serious adverse events. We randomised 29 general wards in a 1:2 allocation, across 5 Australian hospitals to intervention (n = 10) and usual care wards (n = 19). Skilled facilitation over 12 months enabled practitioner-led, ward-level practice change for proactive nursing surveillance. The primary outcome was the rate of medical emergency team activations and secondary outcomes were unplanned intensive care unit admissions, on-ward resuscitations, and unexpected deaths. Outcomes were prospectively collected for 6 months following the initial 6 months of implementation. Analysis was at the patient level using generalised linear mixed models to account for clustering by ward. ResultsWe analysed 29,385 patient admissions to intervention (n = 11,792) and control (n = 17,593) wards. Adjusted models for overall effects suggested the intervention increased the rate of medical emergency team activations (adjusted incidence rate ratio 1.314; 95 % confidence interval 0.975, 1.773), although the confidence interval was compatible with a marginal decrease to a substantial increase in rate. Confidence intervals for secondary outcomes included a range of plausible effects from benefit to harm. However, considerable heterogeneity was observed in intervention effects by patient comorbidity. Among patients with few comorbid conditions in the intervention arm there was a lower medical emergency team activation rate and decreased odds of unexpected death. Among patients with multimorbidity in the intervention arm there were higher rates of medical emergency team activation and intensive care unit admissions. ConclusionTrial outcomes have refined our assumptions about the impact of the ENCORE intervention. The intervention appears to have protective effects for patients with low complexity where frontline teams can respond locally. It also appears to have redistributed medical emergency team activations and unplanned intensive care unit admissions, mobilising higher rates of rescue for patients with multimorbidity.

Effectiveness of Pressure Relief Pads in Preventing Bi-Level Positive Airway Pressure- Related Injuries: A Secondary Database Analysis

<p>目的：透過雙相型陽壓呼吸器(BiPAP)通報資料庫分析，探討減壓墊於BiPAP相關壓傷之預防成效。方法：方便取樣南部某區域教學醫院成人內科加護病房之BiPAP通報資料庫，次級資料分析減壓墊於BiPAP相關壓傷之預防成效。結果：減壓墊組的壓傷發生率為6.06%，無減壓墊組為7.78%，兩組無統計顯著差異(p =.5863)。壓傷個案相關變項比較，減壓墊組比無減壓墊組平均延緩21.18小時產生壓傷(p =.8660)，平均減少0.12個壓傷(p =.5501)、減少1.96 cm2的壓傷表面積(p =.7334)，較低的重度壓傷發生風險(risk ratio = 0.44, p =.1666)，然礙於臨床發生壓傷的個案數偏少，故成效比較尚未達顯著差異。結論：兩組比較雖未達顯著差異，但次級資料庫的真實世界數據顯示減壓墊組具有較佳的預防壓傷臨床效益，建議臨床仍可善用減壓墊於預防BiPAP相關壓傷。</p> <p> </p><p>"Purpose: To compare the effectiveness of pressure relief pads in preventing bi-level positive airway pressure-related injuries by analyzing data from a medical reporting database. Methods: The authors took a convenience sample of records from the medical reporting database of the adult medical intensive care unit of a regional teaching hospital in southern Taiwan. Secondary database analysis was employed to examine the effectiveness of pressure relief pads in preventing pressure injuries. Results: The incidence of pressure-related injuries in the pressure relief pads group was 6.06%, whereas the incidence in the no relief pads group was 7.78% (p = .5863). Pressure relief pads delayed the occurrence of pressure injuries by 21.18 hours (p = .8660), reduced the number of pressure injury lesions by 0.12 (p = .5501), reduced the surface area of pressure injuries by 1.96 cm2 (p = .7334), and reduced the risk of severe pressure injury (risk ratio = 0.44, p = .1666). Due to the small number of clinical incident pressure injuries reported, the comparison of effectiveness did not reach statistical significance. Conclusion: Although no significant difference was observed between the two groups, real-world data from the secondary database revealed that the pressure relief pads effectively and safely prevented pressure injuries.</p> <p> </p>

Does organophosphorus poisoning increase the risk of staphylococcal ventilator associated pneumonia? - a retrospective study.

The aim of this study was to determine the clinical predictors of staphylococcal ventilator-associated pneumonia (VAP) and to compare the outcomes of staphylococcal VAP with non-staphylococcal VAP. A retrospective observational study was conducted among adult patients admitted to the medical intensive care unit (MICU) in a tertiary care hospital in India from January 2017 to December 2019. The patients were grouped based on their diagnosis into staphylococcal and non-staphylococcal VAP, and the baseline characteristics, clinical parameters, co-morbidities, and outcome parameters were compared. Out of 2129 MICU admissions, 456 patients with microbiologically confirmed VAP were included, of which 69 (15.1%) had staphylococcal VAP, and the remaining 387 (84.9%) had non-staphylococcal VAP. Organophosphorus (OP) poisoning was identified as an independent predictor of staphylococcal VAP (odds ratio: 2.57; 95% CI: 1.4 to 4.73). The median duration of mechanical ventilation before VAP diagnosis was less in the staphylococcal VAP group (4 vs. 5 days; p = 0.004). The staphylococcal group also showed a better in-hospital outcome. OP poisoning was an independent predictor of staphylococcal VAP. Staphylococcal VAP was diagnosed earlier in patients than non-staphylococcal VAP. Screening for nasal carriage for Staphylococcus, especially in patients with OP poisoning at the time of MICU admission, may help guide antibiotic therapy.

Implementing pain, agitation, delirium, and sleep deprivation protocol in critically ill patients: A pilot study on pharmacological interventions.

Critically ill patients frequently experience pain, agitation, delirium, and sleep deprivation, which have been linked to increased mortality and unfavorable clinical outcomes. To address these challenges, the Pain, Agitation, Delirium, and Sleep Deprivation (PADS) protocol was developed, aiming to mitigate mortality and improve clinical outcomes. This study focuses on assessing the protocol's impact using a robust before-and-after study design in the medical and surgical intensive care units (ICUs) at Ramathibodi Hospital. Using an observational approach, this study compares clinical outcomes before and after implementing the PADS protocol in the ICUs. Two patient cohorts were identified: the "before" group, comprising 254 patients with retrospective data collected between May 2018 and September 2019, and the "after" group, consisting of 255 patients for whom prospective data was collected from May to September 2020. Analysis reveals improvements in the after group. Specifically, there was a significant increase in 14-day ICU-free days (9.95 days vs. 10.40 days, p value = 0.014), a decrease in delirium incidence (18.1% vs. 16.1%, p value < 0.001), and a significant reduction in benzodiazepine usage (38.6% vs. 24.6%, p value = 0.001) within the after group. This study emphasizes the protocol's potential to improve patient care and highlights its significance in the ICU context.

Temporal Trends in Methamphetamine Use in Patients Admitted to the Hospital: A Retrospective Cohort Study.

Although methamphetamine use is common, the scope of methamphetamine use and outcomes for patients admitted to the hospital is unclear. This study aims to identify the prevalence of methamphetamine use from January 2012 to January 2022, coingestions, hospital course, and readmission rate of admitted patients. This was a retrospective cohort study conducted on patients admitted to our center with the following inclusions: age older than 18 years, positive/"pending confirm" value for methamphetamine on urine drug screen, and/or an International Classification of Diseases , Tenth Revision , code related to stimulant use disorder as an active issue. Urine drug screen data are reported as methamphetamine +/- and polysubstance (PS) +/-. Patient demographics, admission diagnosis, and hospital course were extracted. Statistical tests used included t tests and Mann-Whitney U tests. A total of 19,159 encounters were included, representing 12,057 unique patients. The median (interquartile range) age was 43 (33-54) years. Of all encounters, 35.3% were methamphetamine + and PS -, and 46.3% were methamphetamine + and PS +. Hospitalizations increased from 883 in 2012 to 2532 in 2021. The median (IQR) hospital stay was 48 (48-120) hours. Of all encounters, 16.8% included an intensive care unit (ICU) admission, and the median ICU stay was 42 (21-87) hours. A total of 2988 patients (24.7%) were readmitted within the study period, and 4988 (71.5%) returned within 1 year of the previous encounter. In context of all emergency department admissions from 2013 to 2022, 13.1% had a urine drug screen + for methamphetamine. Hospitalizations with recent methamphetamine use doubled at our institution from 2012 to 2022. In addition, 1 in 4 is readmitted (typically within 1 year), and a minority requires ICU care.

Epidemiology and Outcomes of Critical Illness and Novel Predictors of Mortality in an Ethiopian Medical Intensive Care Unit.

Low- and middle-income countries (LMICs) bear most of the global burden of critical illness. Managing this burden requires improved understanding of epidemiology and outcomes in LMIC intensive care units (ICUs), including LMIC-specific mortality prediction scores. This study was a retrospective observational study at Tikur Anbessa Specialized Hospital in Addis Ababa, Ethiopia, examining all consecutive medical ICU admissions from June 2014 to April 2015. The primary outcome was ICU mortality; secondary outcomes were prolonged ICU stay and prolonged mechanical ventilation. ICU mortality prediction models were created using multivariable logistic regression and compared with the Mortality Probability Model-II (MPM-II). Associations with secondary outcomes were examined with multivariable logistic regression. There were 198 admissions during the study period; mortality was 35%. Age, shock on admission, mechanical ventilation, human immunodeficiency virus, and Glasgow Coma Scale ≤8 were associated with ICU mortality. The receiver operating characteristic curve for this 5-factor model had an AUC of 0.8205 versus 0.7468 for MPM-II, favoring the simplified new model. Mechanical ventilation and lack of shock were associated with prolonged ICU stays. Mortality in an LMIC medical ICU was high. This study examines an LMIC medical ICU population, showing a simplified prediction model may predict mortality as well as complex models.

Evolution of ceftazidime-avibactam and cefiderocol resistance in ST131-H30R1-Escherichia coli isolates with KPC-3 mutants and application of FTIR biotyping.

Ceftazidime-avibactam and cefiderocol represent two of the few alternatives for infections by KPC-producing Enterobacterales. We reported the emergence of resistance to both ceftazidime-avibactam and cefiderocol in a KPC-producing ST131-Escherichia coli (KPC-ST131-Ec) clinical isolate. Antimicrobial susceptibility testing, Fourier-transform infrared (FTIR) spectroscopy, whole-genome sequencing, and cloning experiments were performed. A KPC-49-Ec isolate resistant to ceftazidime-avibactam (MICCZA > 16/4 mg/L) and susceptible to cefiderocol (MICFDC: 2 mg/L) was recovered in a blood sample from an oncologic patient hospitalized in the medical ICU (June 2019) during ceftazidime-avibactam treatment. After 44 days, a KPC-31-Ec resistant to both ceftazidime-avibactam and cefiderocol (MICCZA > 16/4 mg/L, MICFDC: 8 mg/L) was found in a rectal sample during a second cycle of ceftazidime-avibactam treatment. Both KPC-49 (R163S) and KPC-31 (D179Y) were detected in the epidemic ST131-H30R1-Ec high-risk clone and showed a phenotype resembling that of ESBL producers. FTIR spectroscopy managed to differentiate cefiderocol-susceptible and resistant ST131-Ec isolates, and these from others belonging to different clones. After cloning and transformation experiments, KPC-49 and KPC-31 were responsible for ceftazidime-avibactam resistance (MICCZA > 16/4 mg/L) and decreased carbapenem MICs (MICMER ≤ 0.12 mg/L, MICIMI ≤ 1 mg/L). KPC-31 was also shown to be associated with increased MICs of cefiderocol (twofold and threefold dilutions over KPC-3 and KPC-49, respectively). However, mutations in proteins participating in outer membrane stability and integrity, such as TolR, could have a more relevant role in cefiderocol resistance. The effects of ceftazidime-avibactam and cefiderocol co-resistance in clinical isolates of Enterobacterales producing KPC mutants make their identification challenging for clinical laboratories.IMPORTANCEThroughout four admissions in our hospital of a single patient, different KPC-3 variants (KPC-3, KPC-49, and KPC-31) were found in surveillance and clinical ST131-Escherichia coli isolates, after prolonged therapies with meropenem and ceftazidime-avibactam. Different patterns of resistance to cefiderocol and ceftazidime-avibactam emerged, accompanied by restored carbapenem susceptibility. The inability to detect these variants with some phenotypic methods, especially KPC-31 by immunochromatography, and the expression of a phenotype similar to that of ESBL producers, posed challenge to identify these variants in the clinical microbiology laboratory. Molecular methods and whole-genome sequencing are necessary and new techniques able to cluster or differentiate related isolates could also be helpful; this is the case of Fourier-transform infrared spectroscopy, which managed in our study to discriminate isolates by cefiderocol susceptibility within ST131, and those from the non-ST131 ones.

Assessment of β2-Microglobulin as a Marker for Acute Kidney Injury in Patients with Intracerebral Hemorrhage in Medical Intensive Care Unit

THERAPEUTIC APPROACHES FOR ACID REDUCTION IN PATIENTS ADMITTED TO INTENSIVE CARE UNITS WITH A HISTORY OF GASTROESOPHAGEAL REFLUX DISEASE AT A TERTIARY CARE HOSPITAL IN PAKISTAN.

Introduction: Although the prevalence of gastroesophageal reflux disease (GERD) in intensive care units is still unknown, the condition is on the rise all over the world. Patients in critical condition are especially susceptible to gastroesophageal reflux disease (GERD) because of the many procedures and underlying illnesses they undergo. Pepsin levels in oral secretions, ambulatory monitoring, and pH measurement are among procedures that can be utilized in the diagnostic process. The most popular treatment methods consist of adjusting one's lifestyle and using medicine, mainly proton pump inhibitors (PPIs). Methodology: An analysis of data collected from 96 critically sick patients who were getting acid-lowering medication was carried out in retrospective research that was carried out at a tertiary care hospital in AJK, Pakistan between June and December 2023. Results: Most patients were being treated in medical intensive care units (MICU), and the medications that were prescribed the most frequently were omeprazole and esomeprazole. Omeprazole and antacids were the primary maintenance medications that were administered at the time of discharge. Patients who were diagnosed with gastroesophageal reflux disease (GERD) and those who were undergoing mechanical ventilation made up a sizeable share, with most of them receiving intravenous proton pump inhibitors (PPIs). Both potassium-competitive acid blockers and omeprazole were shown to have equivalent levels of treatment efficacy, according to the findings. Conclusion: Most of trials in past have established esomeprazole being highlighted as having superiority in certain studies. On the other hand, newer possibilities such as GABA-B agonist baclofen and P-CABs offer potential lines of investigation. Even though developing medicines require more exploration for routine management, intravenous proton pump inhibitors (PPIs) continue to be the primary emergency treatment for gastroesophageal reflux disease (GERD) in critical care.

Malnutrition and pectoralis muscle index in medical intensive care unit patients: A matched cohort study.

Muscle assessment is an important component of nutrition assessment. The Global Leadership Initiative on Malnutrition (GLIM) consortium recently underscored the need for more objective muscle assessment methods in clinical settings. Various assessment techniques are available; however, many have limitations in clinical populations. Computed tomography (CT) scans, obtained for diagnostic reasons, could serve multiple purposes, including muscle measurement for nutrition assessment. Although CT scans of the chest are commonly performed clinically, there is little research surrounding the utility of pectoralis muscle measurements in nutrition assessment. The primary aim was to determine whether CT-derived measures of pectoralis major cross-sectional area (PMA) and quality (defined as mean pectoralis major Hounsfield units [PMHU]) could be used to identify malnutrition in patients who are mechanically ventilated in an intensive care unit (ICU). A secondary aim was to evaluate the relationship between these measures and clinical outcomes in this population. A retrospective analysis was conducted on 33 pairs of age- and sex-matched adult patients who are being mechanically ventilated in the ICU. Patients were grouped by nutrition status. Analyses were performed to determine differences in PMA and mean PMHU between groups. Associations between muscle and clinical outcomes were also investigated. Compared with nonmalnourished controls, malnourished patients had a significantly lower PMA (P = 0.001) and pectoralis major (PM) index (PMA/height in m2; P = 0.001). No associations were drawn between PM measures and clinical outcomes. These findings regarding CT PM measures lay the groundwork for actualizing the GLIM call to action to validate quantitative, objective muscle assessment methods in clinical settings.

Socio-demographic and comorbid risk factors for poor prognosis in patients hospitalized with community-acquired bacterial pneumonia in southeastern US

BackgroundHow socio-demographic characteristics and comorbidities affect bacterial community-acquired pneumonia (CAP) prognosis during/after hospitalization is important in disease management. ObjectivesTo identify predictors of medical intensive care unit (MICU) admission, length of hospital stay (LOS), in-hospital mortality, and bacterial CAP readmission in patients hospitalized with bacterial CAP. MethodsICD-9/10 codes were used to query electronic medical records to identify a cohort of patients hospitalized for bacterial CAP at a tertiary hospital in Southeastern US between 01/01/2013–12/31/2019. Adjusted accelerated failure time and modified Poisson regression models were used to examine predictors of MICU admission, LOS, in-hospital mortality, and 1-year readmission. ResultsThere were 1956 adults hospitalized with bacterial CAP. Median (interquartile range) LOS was 11 days (6–23), and there were 26 % (513) MICU admission, 14 % (266) in-hospital mortality, and 6 % (117) 1-year readmission with recurrent CAP. MICU admission was associated with heart failure (RR 1.38; 95 % CI 1.17–1.62) and obesity (RR 1.26; 95 % CI 1.04–1.52). Longer LOS was associated with heart failure (adjusted time ratio[TR] 1.27;95 %CI 1.12–1.43), stroke (TR 1.90;95 %CI 1.54,2.35), type 2 diabetes (TR 1.20;95 %CI 1.07–1.36), obesity (TR 1.50;95 %CI 1.31–1.72), Black race (TR 1.17;95 %CI 1.04–1.31), and males (TR 1.24;95 %CI 1.10–1.39). In-hospital mortality was associated with stroke (RR 1.45;95 %CI 1.03–2.04) and age ≥65 years (RR 1.34;95 %CI 1.06–1.68). 1-year readmission was associated with COPD (RR 1.55;95 %CI 1.05–2.27) and underweight BMI (RR 1.74;95 %CI 1.04–2.90). ConclusionsComorbidities and socio-demographic characteristics have varying impacts on bacterial CAP in-hospital prognosis and readmission. More studies are warranted to confirm these findings to develop comprehensive care plans and inform public health interventions.

Evaluating the impact of interprofessional training wards on patient satisfaction and clinical outcomes: a mixed-methods analysis.

Interprofessional teamwork is pivotal in modern healthcare, prompting the establishment of interprofessional training wards since 1996. While these wards serve as hubs for optimizing healthcare professional collaboration and communication, research into patient outcomes remains notably sparse and geographically limited, predominantly examining patient satisfaction and sparingly exploring other metrics like mortality or self-discharge rates. This study seeks to bridge this gap, comparing patient outcomes in interprofessional training wards and conventional wards under the hypothesis that the former offers no disadvantage to patient outcomes. We explored patient outcomes within an interprofessional student ward called A-STAR at a University Hospital from October 2019 to December 2022. Engaging with patients discharged between May 2021 and April 2022, we utilized digital and paper-based anonymous questionnaires, catering to patient preference, to gather pertinent data. Analysis of outcomes for 1,482 A-STAR (interprofessional student ward) and 5,752 conventional ward patients revealed noteworthy findings. A-STAR patients tended to be younger (59 vs. 61 years, p < 0.01) and more frequently male (73.5% vs. 70.4%, p = 0.025). Vital clinical outcomes, such as discharges against medical advice, complication-driven readmissions, and ICU transfers, were statistically similar between groups, as were mortality rates (1.2% vs. 1.3%, p = 0.468). A-STAR demonstrated high patient satisfaction, underscored by positive reflections on team competence, ward atmosphere, and responsiveness to concerns, emphasizing the value placed on interprofessional collaboration. Patient narratives commended team kindness, lucid explanations, and proactive involvement. This data collectively underscores the safety and reliability of patient care within training wards, affirming that patients can trust the care provided in these settings. Patients on the interprofessional ward demonstrated high satisfaction levels: 96.7% appreciated the atmosphere and conduct of ward rounds. In comparison, 98.3% were satisfied with the discussion and information about their treatment during their hospital stay.

Integrating Social Determinants of Health in Critical Care

BackgroundSocial determinants of health (SDOH) mediate outcomes of critical illness. Increasingly, professional organizations recommend screening for social risks. Yet, how clinicians should identify and then incorporate SDOH into acute care practice is poorly defined. Research QuestionHow do medical intensive care unit (ICU) clinicians currently operationalize SDOH within patient care, given that SDOH are known to mediate outcomes of critical illness? Study Design and MethodsUsing ethnographic methods, we observed clinical work rounds in three urban ICUs within a single academic health system to capture use of SDOH during clinical care. Adults admitted to the medical ICU with respiratory failure were prospectively sequentially enrolled. Observers wrote field notes and narrative excerpts from rounding observations. We also reviewed electronic medical record (EMR) documentation for up to 90 days following ICU admission. We then qualitatively coded and triangulated data using a constructivist grounded theory approach and the Centers for Disease Control Healthy People SDOH framework. ResultsSixty-six patients were enrolled and over 200 observation hours of clinical work rounds were included in the analysis. ICU clinicians infrequently integrated social structures of patients’ lives into their discussions. Social structures were most frequently invoked when related to: 1) etiologies of acute respiratory failure, 2) decisions on life sustaining therapies, and 3) transitions of care. There was no systematic way in which data about common SDOH were collected (e.g., food and housing insecurity) and some SDOH were rarely or never discussed (e.g., access to education, discrimination, incarceration). InterpretationClinicians do not incorporate many areas of known SDOH into ICU rounds. Improvements in integration of SDOH should leverage the multidisciplinary team, identifying who is best suited to collect information of SDOH during different timepoints in critical illness. Next steps include clinician, patient-, and caregiver-focused assessments of feasibility and acceptability of an ICU-based SDOH assessment.

Predictive Factors for Physiotherapy Session Length at an Adult Intensive Care Unit: A Longitudinal Panel Study

ObjectiveTo identify predictive factors for the length of physiotherapy sessions for adult intensive care unit (ICU) patients. DesignLongitudinal panel study. SettingICU of a secondary-care public teaching hospital, the University Hospital at the University of Sao Paulo, Brazil. ParticipantsMedical and surgical patients who received physiotherapy (N=181) assessed in 339 physiotherapy sessions.Interventions:Not applicable. Main Outcome MeasuresThe study investigator followed physiotherapists during their work shift and timed the physiotherapy session's length with a stopwatch. The association between session length and patient, physiotherapist, and service-related factors was evaluated by a mixed model. ResultsAssessed in this study were 339 physiotherapy sessions during 79 periods of observation that involved 181 patients and 19 physiotherapists. Median session length was 29 (interquartile range: 22.6-38.9) minutes; median number of patients assisted per physiotherapist per 6-hour shift was 5 (4-5). Physiotherapist's median age was 35 (26-39) years old, and median ICU experience was 13.0 (0.4-16.0) years. Patients were mostly older adults who were post surgery and had been at the ICU for 5 (2-9) days. Factors associated with physiotherapy session length (min) were the following: performing both motor- and respiratory-related physiotherapy procedures during the session (β=6.5; 95% confidence interval [CI], 3.8-9.2), altered chest x-ray (β=2.8; 95% CI, 0.3-5.3), ICU mobility scale (IMS) (β=1.2; 95% CI, 0.4-2.0), contraindication to any level of out-of-bed mobilization (β=–6.9; 95% CI, –10.5 to –3.3), afternoon shift (β=–4.0; 95% CI, –6.7 to –1.4), and Barthel index (β=–0.2; 95% CI, –0.3 to –0.1). ConclusionsThe factors associated with longer session lengths were performing both motor- and respiratory-related physiotherapy procedures during the session, altered chest x-ray, and the IMS. Contraindication to any level of out-of-bed mobilization and sessions performed during the afternoon shift (vs the morning shift) were associated with shorter session lengths.

Characteristics and outcomes of patients with do-not-resuscitate and physician orders for life-sustaining treatment in a medical intensive care unit: a retrospective cohort study

BackgroundIn the intensive care unit (ICU), we may encounter patients who have completed a Do-Not-Resuscitate (DNR) or a Physician Orders to Stop Life-Sustaining Treatment (POLST) document. However, the characteristics of ICU patients who choose DNR/POLST are not well understood.MethodsWe retrospectively analyzed the electronic medical records of 577 patients admitted to a medical ICU from October 2019 to November 2020, focusing on the characteristics of patients according to whether they completed DNR/POLST documents. Patients were categorized into DNR/POLST group and no DNR/POLST group according to whether they completed DNR/POLST documents, and logistic regression analysis was used to evaluate factors influencing DNR/POLST document completion.ResultsA total of 577 patients were admitted to the ICU. Of these, 211 patients (36.6%) had DNR or POLST records. DNR and/or POLST were completed prior to ICU admission in 48 (22.7%) patients. The DNR/POLST group was older (72.9 ± 13.5 vs. 67.6 ± 13.8 years, p < 0.001) and had higher Acute Physiology and Chronic Health Evaluation (APACHE) II score (26.1 ± 9.2 vs. 20.3 ± 7.7, p < 0.001) and clinical frailty scale (5.1 ± 1.4 vs. 4.4 ± 1.4, p < 0.001) than the other groups. Solid tumors, hematologic malignancies, and chronic lung disease were the most common comorbidities in the DNR/POLST groups. The DNR/POLST group had higher ICU and in-hospital mortality and more invasive treatments (arterial line, central line, renal replacement therapy, invasive mechanical ventilation) than the other groups. Body mass index, APAHCE II score, hematologic malignancy, DNR/POLST were factors associated with in-hospital mortality.ConclusionsAmong ICU patients, 36.6% had DNR or POLST orders and received more invasive treatments. This is contrary to the common belief that DNR/POLST patients would receive less invasive treatment and underscores the need to better understand and include end-of-life care as an important ongoing aspect of patient care, along with communication with patients and families.

Clinical characteristics and outcomes of obstetric patients transferred directly to intensive care units.

Medical complications in peripartum patients are uncommon. Often, these patients are transferred to tertiary care centers, but their conditions and outcomes are not well understood. Our study examined peripartum patients transferred to an intensive care unit (ICU) at an academic quaternary center. We reviewed charts of adult, non-trauma, interhospital transfer (IHT) peripartum patients sent to an academic quaternary ICU between January 2017 and December 2021. We conducted a descriptive analysis and used multivariable ordinal regression to examine associations of demographic and clinical factors with ICU length of stay (LOS) and hospital length of stay (HLOS). Of 1,794 IHT peripartum patients, 60 (3.2%) were directly transferred to an ICU. The average was 32 years, with a median Sequential Organ Failure Assessment (SOFA) score of 3 (1-4.25) and Acute Physiology and Chronic Health Evaluation (APACHE) II score of 8 (7-12). Respiratory failure was most common (32%), followed by postpartum hemorrhage (15%) and sepsis (14%). Intubation was required for 24 (41%), and 4 (7%) needed extracorporeal membrane oxygenation. Only 1 (1.7%) died, while 45 (76.3%) were discharged. Median ICU LOS and HLOS were 5 days (212) and 8 days (5-17). High SOFA score was linked to longer HLOS, as was APACHE II. Transfers of critically ill peripartum patients between hospitals were rare but involved severe medical conditions. Despite this, their outcomes were generally positive. Larger studies are needed to confirm our findings.
