Family Member Experiences in Intensive Care Units Care: Insights From a Family Involvement Tool Implementation Trial.

Family involvement is widely considered an important part of patient care in the intensive care unit. From professional health care organizations, government, and hospital associations, there has been a cultural shift toward family presence as part of a wider commitment to patient-centered care. At the same time, the meaning and impact of family involvement in the intensive care unit setting remain opaque and under-studied. This study employed an ethnographic approach to better understand family involvement in practice and from the perspective of health care professionals and family members by studying an implementation trial of a family involvement tool in two intensive care units over 2 years. The findings revealed that an expanded and self-defined role for family members as carers in the intensive care unit challenged the current configuration of the nurse patient/family relationship and that family members were aware of these dynamics. While the intensive care unit implementation teams were both motivated to implement a novel way of facilitating family involvement, the processual, organizational, and contextual factors in the intensive care units largely determined the possibilities of its application. This suggests that interventions should address the specific context in which they are employed.

Initiation of continuous renal replacement therapy versus intermittent hemodialysis in critically ill patients with severe acute kidney injury: a secondary analysis of STARRT-AKI trial.

BACKGROUND: There is controversy regarding the optimal renal-replacement therapy (RRT) modality for critically ill patients with acute kidney injury (AKI). METHODS: We conducted a secondary analysis of the STandard versus Accelerated Renal Replacement Therapy in Acute Kidney Injury (STARRT-AKI) trial to compare outcomes among patients who initiated RRT with either continuous renal replacement therapy (CRRT) or intermittent hemodialysis (IHD). We generated a propensity score for the likelihood of receiving CRRT and used inverse probability of treatment with overlap-weighting to address baseline inter-group differences. The primary outcome was a composite of death or RRT dependence at 90-days after randomization. RESULTS: We identified 1590 trial participants who initially received CRRT and 606 who initially received IHD. The composite outcome of death or RRT dependence at 90-days occurred in 823 (51.8%) patients who commenced CRRT and 329 (54.3%) patients who commenced IHD (unadjusted odds ratio (OR) 0.90; 95% confidence interval (CI) 0.75-1.09). After balancing baseline characteristics with overlap weighting, initial receipt of CRRT was associated with a lower risk of death or RRT dependence at 90-days compared with initial receipt of IHD (OR 0.81; 95% CI 0.66-0.99). This association was predominantly driven by a lower risk of RRT dependence at 90-days (OR 0.61; 95% CI 0.39-0.94). CONCLUSIONS: In critically ill patients with severe AKI, initiation of CRRT, as compared to IHD, was associated with a significant reduction in the composite outcome of death or RRT dependence at 90-days.

Evidence-Based Approaches to Mitigate Workplace Violence From Patients and Visitors in Emergency Departments: A Rapid Review.

INTRODUCTION: This is a rapid review of the published evidence on the effectiveness of interventions for mitigating workplace violence against staff in hospital emergency departments. Focused on the specific needs of an urban emergency department in Canada, this project sought to address the question, "What interventions have evidence regarding effectiveness for addressing workplace patient/visitor violence toward staff in the emergency department?" METHODS: Following Cochrane Rapid Review methods, 5 electronic databases (MEDLINE via PubMed, Cochrane CENTRAL, Embase, PsycINFO, CINAHL) and Google Scholar were searched in April 2022 for intervention studies to reduce or mitigate workplace violence against staff in hospital emergency departments. Critical appraisal was conducted using Joanna Briggs Institute tools. Key study findings were synthesized narratively. RESULTS: Twenty-four studies (21 individual studies, 3 reviews) were included in this rapid review. A variety of strategies for reducing and mitigating workplace violence were identified and categorized as single or multicomponent interventions. Although most studies reported positive outcomes on workplace violence, the articles offered limited descriptions of the interventions and/or lacked robust data to demonstrate effectiveness. Insights from across the studies offer knowledge users information to support the development of comprehensive strategies to reduce workplace violence. DISCUSSION: Despite a large body of literature on workplace violence, there is little guidance on effective strategies to mitigate workplace violence in emergency departments. Evidence suggests that multicomponent approaches targeting staff, patients/visitors, and the emergency department environment are essential to addressing and mitigating workplace violence. More research is needed that provides robust evidence on effective violence prevention interventions.

A randomised open-label trial to assess outpatient induction of labour (HOMEIND) and compare efficacy of Propess vs Dilapan-S® for induction of labour at 39 weeks' gestation in normal risk nulliparous women: study protocol for a randomised controlled trial.

BACKGROUND: Induction of labour (IOL) at 39 weeks has been shown to decrease maternal and neonatal adverse outcomes. Given the growing demand for 39-week IOL, it is imperative that effective methods be assessed for induction in the outpatient setting. The aim of this study is to answer the clinical question as to whether Dilapan-S® vs Propess® as a method of cervical ripening is non-inferior in the outpatient setting at 39 weeks and to ascertain whether Dilapan-S® 12 h is non-inferior to Dilapan-S® 24 h. METHODS: This study is an open-label parallel group single-centre randomised trial. Participants are normal risk nulliparous women who have no pregnancy-related or medical contraindication to IOL. Women will be randomised to one of three induction groups-Dilapan-S® (12-h insertion or 24-h insertion) or Propess. Induction will be initiated between 39+0 and 39+4 weeks' gestation and participants will return home for either 12 or 24 h. They will be readmitted 12/24 h later in order to continue with induction of labour. Patient recruitment will take place over 30 months within a single centre. The study will recruit a maximum 109 women for each study arm. Total duration of participants' involvement in the trial will be 8 weeks to allow for postpartum follow-up. DISCUSSION: This study will definitively answer whether Dilapan-S is non-inferior to Propess® as a method of induction of labour in the outpatient setting and whether cervical ripening with Dilapan-S over a 12-h timeframe is non-inferior to cervical ripening with Dilapan-S over a 24-h timeframe. TRIAL REGISTRATION: EudraCT Number 2019-004697-25 Registered 14 September 2020.

Glycosylated haemoglobin as an indicator of diabetes control in pregnancy: A 10-year review of the relationship between HbA1c trends and delivery outcome in type I and type II diabetes.

BACKGROUND: Pregestational diabetes mellitus (PGDM) confers an increased risk of adverse maternal and neonatal outcomes [1,2]. Glycaemic control in the medium and long term is commonly evaluated by examining glycosylated haemoglobin (HbA1c) levels. However, the value of HbA1c in pregnancy may be diminished by increased level of red cell turnover characteristic of pregnancy [3,4]. We sought to examine the impact of HbA1c in the first trimester and pre-delivery, and the within-patient change throughout gestation on mode of delivery and birthweight in pregnancies complicated by a pre-pregnancy diagnosis of type I or type II diabetes. METHODS: A 10-year consecutive cohort of pregnancies complicated by PGDM, from Jan 2010 until Dec 2019, was examined for HbA1c data in the first trimester and within 6 weeks of delivery. Perinatal outcome data, including gestational age at delivery, mode of delivery and birthweight centile, were obtained from hospital records. The Spearman Rank correlation was used to correlate HcA1c levels in the first trimester with birthweight centiles. Non-parametric summaries and rank-based tests, Signed-rank test and Kruskal-Wallis test, were used to compare Hba1c levels. RESULTS: During the 10-year study period, a consecutive cohort of 396 pregnancies that attained a viable gestational age (>24 weeks' gestation) and complicated by pregestational diabetes was identified; representing 81 % of the population of pregestational diabetic pregnancies managed by this service during the study period. The median [IQR] HbA1c levels (mmol/mol) in the first trimester, pre-delivery and the differential across gestation were 51 [19] mmol/mol, 43 [11] mmol/mol and -8 [13] mmol/mol, respectively. A statistically significant reduction in HbA1c levels throughout gestation was observed (p < 0.001). The median [IQR] birthweight centile was 69 [50 - 96]. The distributions in HbA1c levels and birthweight centiles were heavily skewed. No correlation was identified between HbA1c levels and mode of delivery. CONCLUSION: Neither baseline HbA1c levels, pre-delivery values, nor trends across gestation appear to impact birthweight centile or mode of delivery in PGDM. While optimising glycaemic control can affect the long term health of the mother, these indices cannot be relied upon to reflect the impact of glycaemic control on fetal growth aberrations that influence mode of delivery.

Trends in the role of security services in the delivery of emergency department care.

BACKGROUND: Security services in most settings are an essential part of emergency department (ED) care, but their role remains poorly understood. We sought to:(1) identify the frequency of security services involvement in ED care;(2) characterise the events security services are called for; and (3) identify temporal trends in use. METHODS: We used a hospital-wide security database at a tertiary care ED in downtown Toronto, Ontario. Data from January 2017 to June 2021 related to the ED, patient or visitor related safety calls were included. We categorised calls by type of event (e.g.: Code White or Restraints). Call numbers were calculated as rates to adjust for visit volumes for each period. Univariate analyses were used to assess association between security services' calls and shift time, day of week, and month of the year. RESULTS: Over the 4.5-year study period, 20,033 ED-related calls were recorded. On average, we identified 61 calls per 1000 patient visits. On univariate analysis, no increase in security calls were found based on day of week or month, but a disproportionate number of security calls were recorded overnight. CONCLUSION: This study reveals high security services involvement in the delivery of care in one urban ED. Security databases can inform improvement work and could be augmented by better coding of violent events and linkage with electronic health records when involving patients.

RéSUMé : CONTEXTE: Dans la plupart des contextes, les services de sécurité constituent un élément essentiel des soins dispensés dans les services d'urgence, mais leur rôle reste mal compris. Nous avons cherché à: (1) identifier la fréquence de l'intervention des services de sécurité dans les soins aux urgences; (2) caractériser les événements pour lesquels les services de sécurité sont requis; et (3) identifier les tendances temporelles de l'utilisation. MéTHODES: Nous avons utilisé une base de données de sécurité à l'échelle de l'hôpital dans un service d'urgence de soins tertiaires du centre-ville de Toronto, en Ontario. Les données de janvier 2017 à juin 2021 relatives aux appels de sécurité liés aux urgences, aux patients ou aux visiteurs ont été incluses. Nous avons catégorisé les appels par type d'événement (par exemple : Code blanc ou Contraintes). Les nombres d'appels ont été calculés sous forme de taux afin d'ajuster les volumes de visites pour chaque période. Des analyses univariées ont été utilisées pour évaluer l'association entre les appels des services de sécurité et l'heure du quart de travail, le jour de la semaine et le mois de l'année. RéSULTATS: Au cours des 4,5 années de l'étude, 20 033 appels liés aux urgences ont été enregistrés. En moyenne, nous avons recensé 61 appels pour 1 000 visites de patients. L'analyse univariée n'a révélé aucune augmentation des appels de sécurité en fonction du jour de la semaine ou du mois, mais un nombre disproportionné d'appels de sécurité a été enregistré pendant la nuit. CONCLUSION: Cette étude révèle une forte implication des services de sécurité dans la prestation des soins dans un service d'urgence urbain. Les bases de données sur la sécurité peuvent servir de base aux travaux d'amélioration et pourraient être complétées par un meilleur codage des événements violents et une liaison avec les dossiers médicaux électroniques lorsqu'ils concernent des patients.

Impact of renal-replacement therapy strategies on outcomes for patients with chronic kidney disease: a secondary analysis of the STARRT-AKI trial.

PURPOSE: To assess whether pre-existing chronic kidney disease (CKD) modified the relationship between the strategy for renal-replacement theraphy (RRT) initiation and clinical outcomes in the STARRT-AKI trial. METHODS: This was a secondary analysis of a multi-national randomized trial. We included patients who had documented pre-existing estimated glomerular filtration rate (eGFR) data prior to hospitalization, and we defined CKD as an eGFR ≤ 59 mL/min/1.73 m2. The primary outcome was all-cause mortality at 90 days. Secondary outcomes included RRT dependence and RRT-free days at 90 days. We used logistic and linear regression and interaction testing to explore the effect of RRT initiation strategy on outcomes by CKD status. RESULTS: We studied 1121 patients who had pre-hospital measures of kidney function. Of these, 432 patients (38.5%) had CKD. The median (IQR) baseline serum creatinine was 130 (114-160) and 76 (64-90) µmol/L for those with and without CKD, respectively. Patients with CKD were older and more likely to have cardiovascular comorbidities and diabetes mellitus. Patients with CKD had higher 90-day mortality (47% vs. 40%, p < 0.001) compared to those without CKD, though this was not significant after covariate adjustment (adjusted odds ratio [aOR], 1.05; 95% CI, 0.79-1.41). Patients with CKD were more likely to remain RRT dependent at 90 days (14% vs. 8%; aOR, 1.89; 95% CI, 1.05-3.43). CKD status did not modify the effect of RRT initiation strategy on 90-day mortality. Among patients with CKD, allocation to the accelerated strategy conferred more than threefold greater odds of RRT dependence at 90 days (aOR 3.18; 95% CI, 1.41-7.91) compared with the standard strategy, whereas RRT initiation strategy had no effect on this outcome among those without CKD (aOR 0.71; 95% CI, 0.34-1.47, p value for interaction, 0.009). CONCLUSION: In this secondary analysis of the STARRT-AKI trial, an accelerated strategy of RRT initiation conferred a higher risk of 90-day RRT dependence among patients with pre-existing CKD; however, no effect was observed in the absence of CKD.

PCR vs karyotype for CVS and amniocentesis-the experience at one tertiary fetal medicine unit.

PURPOSE: Despite the rise of non-invasive screening tests for fetal aneuploidy, invasive testing during pregnancy remains the definitive diagnostic tool for fetal genetic anomalies. Results are rapidly available with polymerase chain reaction (PCR) tests, but cases have been reported whereby initial results were not confirmed after pregnancy termination and the fetal karyotype was ultimately normal. We sought to examine the potential discordance between PCR and karyotype for fetal aneuploidy. METHODS: The results from all amniocentesis and CVS tests performed over a 6-year period in a large tertiary level fetal medicine unit were reviewed. The results of PCR and karyotype were recorded and discrepancies examined. Pregnancy outcomes were also recorded. RESULTS: A total of 1222 invasive tests were performed (716 amniocentesis and 506 CVS). Within the cohort having amniocentesis, 11 had discrepant results (normal QF-PCR result but with a subsequent abnormal karyotype). There was 1 case among this group which QF-PCR should have identified. Within the CVS group, 7 patients had discrepant results. All had a diploid QF-PCR and would not have been identified as abnormal by it. CONCLUSION: PCR can be reliably used to determine aneuploidy of chromosomes 13, 18, and 21. However, in cases of sex chromosome aneuploidy, its performance is less reliable and warrants waiting for a complete karyotype. Given such discordance, we advise waiting for karyotype for all invasive tests performed in the presence of a normal ultrasound before advising a patient of a diploid QF-PCR result or potentially terminating a normal pregnancy.

Defining and Redefining Family Involvement in Practice: An Implementation Trial of a Locally Adaptable Patient-Centered Professional Development Tool in Two Ontario Intensive Care Units.

ABSTRACT: Research on best practices for family member involvement has shown that such involvement improves care quality in critical care settings and helps to reduce medical errors leading to adverse events. Although many critical care units promote the principle of "patient-centered care" and family member involvement, there can be a significant gap between knowledge about these processes and their translation into practice. This article is based on an implementation trial of a patient and family involvement knowledge-based tool that involves an educational component for frontline health care workers. By combining ethnographic observation, semistructured interviews, focus groups, and document analysis, we were able to not only examine health care provider views on family involvement but also explore the areas of tension that arose in practice because the introduction of the family involvement tool exposed local factors that shaped the conditions of possibility of family involvement. In particular, unspoken preferences, assumptions, and concerns about family involvement were brought to the fore because this intervention disrupted well-entrenched power dynamics related to family involvement and professional boundaries. Through this ethnographic research, we found that the concept of patient-centered care is not uncontroversial among health care providers and that the form of its practice was largely up for individual interpretation. Interventions and policies that aim to promote patient-centered and family-centered care would benefit from addressing the ways in which these ideas affect the work of different health care professionals and incorporating nursing concerns around family involvement.

One-Year Readmission Following Undifferentiated Acute Hypercapnic Respiratory Failure.

Patients with acute hypercapnic respiratory failure (AHRF) often require hospitalization and respiratory support. Early identification of patients at risk of readmission would be helpful. We evaluated 1-y readmission and mortality rates of patients admitted for undifferentiated AHRF and identified the impact of initial severity on clinically important outcomes. We retrospectively analyzed patients who presented with AHRF to the emergency department of St Michael's Hospital in 2017. We collected data about patients' characteristics, hospital admission, readmission and mortality one year after the index admission. We analyzed predictors of readmission and mortality and conducted a survival analysis comparing patients who did and did not receive ventilatory support. A cohort of 212 patients with AHRF who survived their hospital admission were analyzed. At one year, 150 patients (70.8%) were readmitted and 19 (9%) had died. Main diagnoses included chronic obstructive pulmonary disease (60%), congestive heart failure (36%), asthma (22%) and obesity (19%), and these categories of patients had similar 1 y readmission rates. One third had more than one coexisting chronic illness. Although comorbidities were more frequent in readmitted patients, only a history of previous hospital admissions remained associated with 1 y readmission and mortality in multivariate analysis. Need for ventilatory support at admission was not associated with higher 1 y probability of readmission or death. Undifferentiated AHRF is the presentation of multiple chronic illnesses. Patients who survive one episode of AHRF and with previous history of admission have the highest risk of readmission and death regardless of whether they receive ventilatory support during index admission.

Effect of oral chlorhexidine de-adoption and implementation of an oral care bundle on mortality for mechanically ventilated patients in the intensive care unit (CHORAL): a multi-center stepped wedge cluster-randomized controlled trial.

PURPOSE: Oral chlorhexidine is used widely for mechanically ventilated patients to prevent pneumonia, but recent studies show an association with excess mortality. We examined whether de-adoption of chlorhexidine and parallel implementation of a standardized oral care bundle reduces intensive care unit (ICU) mortality in mechanically ventilated patients. METHODS: A stepped wedge cluster-randomized controlled trial with concurrent process evaluation in 6 ICUs in Toronto, Canada. Clusters were randomized to de-adopt chlorhexidine and implement a standardized oral care bundle at 2-month intervals. The primary outcome was ICU mortality. Secondary outcomes were time to infection-related ventilator-associated complications (IVACs), oral procedural pain and oral health dysfunction. An exploratory post hoc analysis examined time to extubation in survivors. RESULTS: A total of 3260 patients were enrolled; 1560 control, 1700 intervention. ICU mortality for the intervention and control periods were 399 (23.5%) and 330 (21.2%), respectively (adjusted odds ratio [aOR], 1.13; 95% confidence interval [CI] 0.82 to 1.54; P = 0.46). Time to IVACs (adjusted hazard ratio [aHR], 1.06; 95% CI 0.44 to 2.57; P = 0.90), time to extubation (aHR 1.03; 95% CI 0.85 to 1.23; P = 0.79) (survivors) and oral procedural pain (aOR, 0.62; 95% CI 0.34 to 1.10; P = 0.10) were similar between control and intervention periods. However, oral health dysfunction scores (- 0.96; 95% CI - 1.75 to - 0.17; P = 0.02) improved in the intervention period. CONCLUSION: Among mechanically ventilated ICU patients, no benefit was observed for de-adoption of chlorhexidine and implementation of an oral care bundle on ICU mortality, IVACs, oral procedural pain, or time to extubation. The intervention may improve oral health.

Interventions to enable communication for adult patients requiring an artificial airway with or without mechanical ventilator support.

BACKGROUND: Inability to communicate in a manner that can be understood causes extreme distress for people requiring an artificial airway and has implications for care quality and patient safety. Options for aided communication include non-vocal, speech-generating, and voice-enabling aids. OBJECTIVES: To assess effectiveness of communication aids for people requiring an artificial airway (endotracheal or tracheostomy tube), defined as the proportion of people able to: use a non-vocal communication aid to communicate at least one symptom, need, or preference; or use a voice-enabling communication aid to phonate to produce at least one intelligible word. To assess time to communication/phonation; perceptions of communication; communication quality/success; quality of life; psychological distress; length of stay and costs; and adverse events. SEARCH METHODS: We searched the Cochrane Library (Wiley version), MEDLINE (OvidSP), Embase (OvidSP), three other databases, and grey literature from inception to 30 July 2020. SELECTION CRITERIA: We included randomised controlled trials (RCTs), quasi-RCTs, cluster-RCTs, controlled non-randomised parallel group, and before-after studies evaluating communication aids used in adults with an artificial airway. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures recommended by Cochrane. Two review authors independently performed data extraction and assessment of risk of bias. MAIN RESULTS: We included 11 studies (1931 participants) conducted in intensive care units (ICUs). Eight evaluated non-vocal communication aids and three voice-enabling aids. Usual care was the comparator for all. For six studies, this comprised no aid; usual care in the remaining five studies comprised use of various communication aids. Overall, our confidence in results regarding effectiveness of communication interventions was very low due to imprecision, measurement heterogeneity, inconsistency in results, and most studies at high or unclear risk of bias across multiple domains. No non-vocal aid studies reported our primary outcome. We are uncertain of the effects of early use of a voice-enabling aid compared to routine use on ability to phonate at least one intelligible word (risk ratio (RR) 3.03, 95% confidence interval (CI) 0.18 to 50.08; 2 studies; very low-certainty evidence). Compared to usual care without aids, we are uncertain about effects of a non-vocal aid (communication board) on patient satisfaction (standardised mean difference (SMD) 2.92, 95% CI 1.52 to 4.33; 4 studies; very low-certainty evidence). No studies of non-vocal aids reported quality of life. Low-certainty evidence from two studies suggests early use of a voice-enabling aid may have no effect on quality of life (MD 2.27, 95% CI -7.21 to 11.75). Conceptual differences in measures of psychological distress precluded data pooling; however, intervention arm participants reported less distress suggesting there might be benefit, but our certainty in the evidence is very low. Low-certainty evidence suggest voice-enabling aids have little or no effect on ICU length of stay; we were unable to determine effects of non-vocal aids. Three studies reported different adverse events (physical restraint use, bleeding following tracheostomy, and respiratory parameters indicating respiratory decompensation). Adverse event rates were similar between arms in all three studies. However, uncertainty remains as to any harm associated with communication aids. AUTHORS' CONCLUSIONS: Due to a lack of high-quality studies, imprecision, inconsistency of results, and measurement heterogeneity,  the evidence provides insufficient information to guide practice as to which communication aid is more appropriate and when to use them. Understanding effectiveness of communication aids would benefit from development of a core outcome measurement set.
