Protocol-driven care in the intensive care unit: a tool for quality

Mobilizing Progress: A Comprehensive Review of the Efficacy of Early Mobilization Therapy in the Intensive Care Unit

Early mobilization therapy has emerged as a crucial aspect of intensive care unit (ICU) management, aiming to counteract the detrimental effects of prolonged immobility in critically ill patients. This comprehensive review examines the efficacy of early mobilization therapy in the ICU setting, synthesizing evidence from clinical trials, meta-analyses, and guidelines. Key findings indicate that early mobilization is associated with numerous benefits, including reduced muscle weakness, a shorter duration of mechanical ventilation, decreased ICU and hospital length of stay, and improved functional outcomes. However, safety concerns, staffing limitations, and patient-specific considerations pose significant barriers to widespread adoption. Despite these challenges, early mobilization is important for improving ICU patient outcomes. This review underscores the critical need for continued research and implementation efforts to optimize early mobilization protocols, address remaining challenges, and expand access to this beneficial therapy. By working collaboratively to overcome barriers and prioritize early mobilization, healthcare providers can enhance the quality of care and improve outcomes for critically ill patients in the ICU.

An integrative review of potassium replacement protocol use in critical care: Development, use and critical care nurse autonomy

BACKGROUND

Potassium replacement protocols are used to standardise practice, reduce risk, and ensure timely potassium replacement, but there is considerable variability in their development and use, particularly as part of critical care nursing practice.

AIM

To synthesise the research evidence on how potassium replacement protocols are used in adult critical care; and how critical care nurses' role and practice is influenced by a potassium replacement protocol. The research question was 'How are protocols used by intensive care clinicians to guide potassium replacement in adult critical care?'

DESIGN

A structured integrative review was undertaken. A combination of keywords, synonyms, and Medical Subject Headings were used across the Ovid Medline and Embase databases. Records were independently assessed against inclusion and exclusion criteria. All papers were assessed for quality. A narrative synthesis was used to analyse and present the findings.

RESULTS

Ten studies were included in this review from 4076 records identified. Narrative synthesis revealed five categories: (i) protocol design demonstrating variation in protocol mechanisms, (ii) protocol rationale eliciting reasonings for protocol implementation, (iii) protocol use describing how protocols were nurse-driven enabling nursing autonomy (iv) protocol adherence highlighting variability in protocol compliance and (v) critical care nurse acceptability and feasibility coupling greater shared responsibility for patient care and improved clinician satisfaction.

CONCLUSION

Safe, high-quality care, supported by evidence continues to be a priority. Protocolised potassium replacement can improve patient outcomes and promote nurses' autonomy, efficiency, and job satisfaction.

IMPLICATIONS FOR CLINICAL PRACTICE

Recognising and promoting critical care nurses' expert assessment skills and clinical decision-making is essential for optimising efficient, safe, and high-quality patient care. Although protocol deviations are accommodated in protocol development, comprehensive documentation to justify protocol deviations is key to justifying practice. Understanding protocol deviations are crucial to inform future protocol development, improvements, and evaluation to further enhance critical care nursing practice.

Assessment of Electrolyte Replacement in Critically Ill Patients During a Drug Shortage

Purpose: The purpose of this study was to determine if national drug shortages of electrolyte replacement products negatively impact patient care. Methods: This study was a single-center, retrospective, observational cohort of adults admitted to the medical, surgical, or trauma intensive care unit (ICU) that were ordered or would have qualified for the general or continuous renal replacement therapy electrolyte replacement protocol (ERP) between April 2017 and August 2018. In October 2017, ERP use was suspended and enteral replacement was promoted due to inability to maintain consistent inventory of intravenous replacement products. The primary objective was to compare the percentage of patient days that at least 1 critically low value of potassium, magnesium, and/or phosphorus existed between protocolized and nonprotocolized electrolyte replacement. Secondary objectives included characterizing the ratio of enteral replacement to duration of critically low electrolyte values during protocolized and nonprotocolized electrolyte replacement. Results: A total of 288 patients were included. The mean percentage of ICU days with low electrolyte levels in the protocolized period was significantly higher than in the nonprotocolized period (21.4% vs 17.5%, P = .0238). There was a negative relationship between the total electrolyte replacement that was given enterally and the percentage of patient days with critically low values indicating that as enteral replacement increased, percentage of days with low values decreased. The association between percentage of enteral replacement and days with critically low electrolyte values was significantly lower in the protocolized period. Conclusion: Intravenous electrolyte replacement product shortages did not result in an increased incidence of critically low electrolyte values. Enteral replacement was associated with a decreased incidence of low electrolyte values.

Protocol Adherence in the Intensive Care Unit for the Management of Adult Patients Admitted with Acute Aneurysmal Subarachnoid Hemorrhage

Background There are recognized protocols that exist for management with minimal data regarding protocol adherence. We conducted a retrospective analysis of aneurysmal subarachnoid hemorrhage (aSAH) to determine whether the level of protocol adherence varied based on patient demographics or specific aspects of management.

Materials and Methods All cases of aSAH admitted to a tertiary-level intensive care unit (ICU) from 2014 to 2016 were identified from the Australia and New Zealand Intensive Care Society Core Database as well as the clinical records system. ICU demographic and descriptive data for protocol adherence, were collected from admission to discharge up to 22 days, or until death whichever was earlier.

Results A total of 58 cases of aSAH were registered; mean age was 56.7 years, 70.7% of patients were female, and mean length of stay was 12.6 days. World Federation of Neurosurgical Societies (WFNS) scale was documented more than Fisher grading. Of the 58 cases, 63.7% (37) underwent surgical clipping, with 83.7% (30) patients having this surgery within 48 hours. SBP/MAP were the most consistently recorded observations within protocol ranges, with adherence of 82.4% and 82.1%, respectively. Thirty-two percent of temperature measurements were outside of the normothermic range of 36.5 to 37.5°C with a mean adherence of 47.5% (standard deviation = ±0.24, median = 40). There was no correlation between adherence and patient, disease, or admission factors.

Conclusion This study demonstrated that there was no association between variation in protocol adherence based on age, admission dates, or disease factors including WFNS grade and Fisher scale. Best protocol adherence protocol for the management of aSAH within the ICU was blood pressure control. Areas for improvement were documentation of the WFNS and Fisher grading, and temperature measurement and management.

INTRAVENOUS PAMIDRONATE IS ASSOCIATED WITH REDUCED MORTALITY IN PATIENTS WITH CHRONIC CRITICAL ILLNESS

OBJECTIVE

Chronic critical illness (CCI), characterized by prolonged mechanical ventilation and tracheostomy, commonly manifests with elevated bone resorption, which has previously been shown to abate after treatment with intravenous (IV) bisphosphonates. Our study assessed the impact of pamidronate administration on clinical outcomes in a CCI cohort.

METHODS

A retrospective case series was performed on 148 patients admitted to The Mount Sinai Hospital Respiratory Care Unit (RCU) from 2009-2010. We identified patients with CCI who did (n = 30) or did not (n = 118) receive IV pamidronate (30 to 90 mg). Both groups included patients with normal and abnormal renal function. Pamidronate was administered for elevated urine or serum N-telopeptide, hypercalciuria, or hypercalcemia.

RESULTS

RCU and 1-year mortality were significantly lower in the pamidronate group (0 and 20%, respectively) compared to nonreceivers (19 and 56%, respectively) (P = .0077 and P = .0004, respectively). After adjusting for differences in baseline creatinine, estimated glomerular filtration rate, and serum calcium, the association with reduced mortality remained significant at 1 year (P = .0132) and with borderline significance for RCU mortality (P = .0911). Creatinine was significantly lower 7 days following pamidronate administration (P = .0025), with no significant difference at 14 days compared to baseline. Pamidronate receivers showed a greater increase in albumin during the RCU stay (2.49 to 3.23 g/dL), compared to nonreceivers (2.43 to 2.64 g/dL) (P = .0007). Pamidronate administration was associated with a significantly reduced rate of hypoglycemia compared to RCU patients not receiving pamidronate (0.09 versus 0.12; P = .0071).

CONCLUSION

Pamidronate use in a CCI population is associated with reduced mortality, lower hypoglycemia rates, improved albumin, and stable renal function.

Maternal critical care: 'one small step for woman, one giant leap for womankind'

PURPOSE OF REVIEW

The purpose of this study is to outline the challenges of looking after women who either become or are at a risk of becoming critically ill during pregnancy.

RECENT FINDINGS

In recent years, there has been an increased demand in the need for maternal critical care. This is partly due to women with complex medical conditions surviving to child-bearing age, coupled with improvements in foetal medicine resulting in more high-risk pregnancies reaching term.

SUMMARY

In this review, we identify the need for maternal critical care, explore different models of its provision and outline possible benefits and barriers to its future implementation.

Use of Management Pathways or Algorithms in Children With Chronic Cough: Systematic Reviews

BACKGROUND

Use of appropriate cough pathways or algorithms may reduce the morbidity of chronic cough, lead to earlier diagnosis of chronic underlying illness, and reduce unnecessary costs and medications. We undertook three systematic reviews to examine three related key questions (KQ): In children aged ?14 years with chronic cough (> 4 weeks' duration), KQ1, do cough management protocols (or algorithms) improve clinical outcomes? KQ2, should the cough management or testing algorithm differ depending on the duration and/or severity? KQ3, should the cough management or testing algorithm differ depending on the associated characteristics of the cough and clinical history?

METHODS

We used the CHEST expert cough panel's protocol. Two authors screened searches and selected and extracted data. Only systematic reviews, randomized controlled trials (RCTs), and cohort studies published in English were included.

RESULTS

Data were presented in Preferred Reporting Items for Systematic Reviews and Meta-analyses flowcharts and summary tabulated. Nine studies were included in KQ1 (RCT = 1; cohort studies = 7) and eight in KQ3 (RCT = 2; cohort = 6), but none in KQ2.

CONCLUSIONS

There is high-quality evidence that in children aged ?14 years with chronic cough (> 4 weeks' duration), the use of cough management protocols (or algorithms) improves clinical outcomes and cough management or the testing algorithm should differ depending on the associated characteristics of the cough and clinical history. It remains uncertain whether the management or testing algorithm should depend on the duration or severity of chronic cough. Pending new data, chronic cough in children should be defined as > 4 weeks' duration and children should be systematically evaluated with treatment targeted to the underlying cause irrespective of the cough severity.

Establishing the Content Validity of an Early Extubation Protocol: A Quality Improvement Project for Improving Early Extubation of Coronary Artery Bypass Graft Patients

Introduction: Patients undergoing coronary artery bypass graft surgery will require intubation and the use of mechanical ventilation during and after surgery. It is well accepted that early extubation is associated with not only positive patient outcomes but also organizational outcomes as well. Patients who are not extubated early are at risk for complications associated with prolonged intubation. The literature supports the use of protocol aid with early extubation. The goal and expected outcome of this project is to establish the usability of an early extubation protocol by assessing its appropriateness for use in the postoperative cardiac surgical adult patient. Methods: For the purpose of establishing content validity of an early extubation protocol, 2 protocols were chosen from the literature. Fifteen cardiac surgery experts were invited to select the protocol they felt was most appropriate for use in this patient population. These reviewers were then asked to further analyze the protocol based on a 5-question survey. Their response was used to calculate a scale-content validity index (S-CVI) and an item-content validity index (I-CVI). Results: Twelve of 15 experts participated in the project. The content validity was estimated using (a) interrater agreement for relevance for each item (I-CVI) and (b) S-CVI. The means were established for each item. Content validity was estimated using (a) interrater agreement for relevance for each item (I-CVI: 0.75-1.00); and the S-CVI/average = 0.92. Cronbach's alpha was estimated to establish reliability (0.972). Conclusion: Selecting an appropriate protocol to be used in this patient population is the first step in implementing an effective early extubation process. The results highly suggest that the content of this protocol is quite relevant in this patient population. It is hoped that this will set the stage for early extubation in postoperative cardiac surgery patients.

Renal replacement therapy in adult and pediatric intensive care : Recommendations by an expert panel from the French Intensive Care Society (SRLF) with the French Society of Anesthesia Intensive Care (SFAR) French Group for Pediatric Intensive Care Emergencies (GFRUP) the French Dialysis Society (SFD)

Acute renal failure (ARF) in critically ill patients is currently very frequent and requires renal replacement therapy (RRT) in many patients. During the last 15 years, several studies have considered important issues regarding the use of RRT in ARF, like the time to initiate the therapy, the dialysis dose, the types of catheter, the choice of technique, and anticoagulation. However, despite an abundant literature, conflicting results do not provide evidence on RRT implementation. We present herein recommendations for the use of RRT in adult and pediatric intensive care developed with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system by an expert group of French Intensive Care Society (SRLF), with the participation of the French Society of Anesthesia and Intensive Care (SFAR), the French Group for Pediatric Intensive Care and Emergencies (GFRUP), and the French Dialysis Society (SFD). The recommendations cover 4 fields: criteria for RRT initiation, technical aspects (access routes, membranes, anticoagulation, reverse osmosis water), practical aspects (choice of the method, peritoneal dialysis, dialysis dose, adjustments), and safety (procedures and training, dialysis catheter management, extracorporeal circuit set-up). These recommendations have been designed on a practical point of view to provide guidance for intensivists in their daily practice.

Proposed management algorithm for severe hypoxemia after liver transplantation in the hepatopulmonary syndrome

The hepatopulmonary syndrome (HPS) is defined as the triad of liver disease, intrapulmonary vascular dilatation, and abnormal gas exchange, and is found in 10-32% of patients with liver disease. Liver transplantation is the only known cure for HPS, but patients can develop severe posttransplant hypoxemia, defined as a need for 100% inspired oxygen to maintain a saturation of ≥85%. This complication is seen in 6-21% of patients and carries a 45% mortality. Its management requires the application of specific strategies targeting the underlying physiologic abnormalities in HPS, but awareness of these strategies and knowledge on their optimal use is limited. We reviewed existing literature to identify strategies that can be used for this complication, and developed a clinical management algorithm based on best evidence and expert opinion. Evidence was limited to case reports and case series, and we determined which treatments to include in the algorithm and their recommended sequence based on their relative likelihood of success, invasiveness, and risk. Recommended therapies include: Trendelenburg positioning, inhaled epoprostenol or nitric oxide, methylene blue, embolization of abnormal pulmonary vessels, and extracorporeal life support. Availability and use of this pragmatic algorithm may improve management of this complication, and will benefit from prospective validation.

Variation of arterial and central venous catheter use in United States intensive care units

BACKGROUND

Arterial catheters (ACs) and central venous catheters (CVCs) are common in intensive care units (ICUs). Few data describe which patients receive these devices and whether variability in practice exists.

METHODS

The authors conducted an observational cohort study on adult patients admitted to ICU during 2001-2008 by using Project IMPACT to determine whether AC and CVC use is consistent across U.S. ICUs. The authors examined trends over time and patients more (mechanically ventilated or on vasopressors) or less (predicted risk of hospital mortality ≤2%) likely to receive either catheter.

RESULTS

Our cohort included 334,123 patients across 122 hospitals and 168 ICUs. Unadjusted AC usage rates remained constant (36.9% [2001] vs. 36.4% [2008]; P = 0.212), whereas CVC use increased (from 33.4% [2001] to 43.8% [2008]; P < 0.001 comparing 2001 and 2008); adjusted AC usage rates were constant from 2004 (35.2%) to 2008 (36.4%; P = 0.43 for trend). Surgical ICUs used both catheters most often (unadjusted rates, ACs: 56.0% of patients vs. 22.4% in medical and 32.6% in combined units, P < 0.001; CVCs: 46.9% vs. 32.5% and 36.4%, P < 0.001). There was a wide variability in AC use across ICUs in patients receiving mechanical ventilation (median [interquartile range], 49.2% [29.9-72.3%]; adjusted median odds ratio [AMOR], 2.56), vasopressors (51.7% [30.8-76.2%]; AMOR, 2.64), and with predicted mortality of 2% or less (31.7% [19.5-49.3%]; AMOR, 1.94). There was less variability in CVC use (mechanical ventilation: 63.4% [54.9-72.9%], AMOR, 1.69; vasopressors: 71.4% (59.5-85.7%), AMOR, 1.93; predicted mortality of 2% or less: 18.7% (11.9-27.3%), AMOR, 1.90).

CONCLUSIONS

Both ACs and CVCs are common in ICU patients. There is more variation in use of ACs than CVCs.

Measurable outcomes of quality improvement using a daily quality rounds checklist: two-year prospective analysis of sustainability in a surgical intensive care unit

BACKGROUND

The use of a "quality rounds checklist" (QRC) is an effective tool for improving compliance with evidence-based preventative measures and outcomes in the surgical intensive care unit (SICU). Our aim was to evaluate the long-term sustainability and outcome impact of this quality improvement strategy.

METHODS

Prospective observational study evaluates the use of the QRC in the SICU from July 2009 to June 2011. Daily compliance with evidence-based prophylactic measures was assessed using the QRC and reviewed monthly at a multidisciplinary meeting. Logistic regression was performed to evaluate patterns of compliance over time. Current compliance was compared with previously reported rates, and the impact on outcomes including catheter-related blood stream infection and ventilator-associated pneumonia rates was examined.

RESULTS

Over 2 years, 2,472 patients were admitted to the SICU. Mean (SD) age was 42.2 (22.4) years, 79% were male, and 35% had an Injury Severity Score (ISS) of greater than 15. The rate of compliance with head-of-bed elevation significantly improved during the study period (p = 0.01 for trend), with an overall compliance of 97%. Both deep venous thrombosis prophylaxis and gastrointestinal bleed prophylaxis compliance remained stable, with overall rates of 98% and 96%, respectively. The use of sedation holidays also remained stable, with an overall compliance rate of 94%. Compared with our previously published data, the compliance rates with preventative measures were stable or significantly improved; the incidence of catheter-related blood stream infections was lower (0.85/1,000 vs. 4.98/1,000 catheter days, p < 0.001); and the incidence of ventilator-associated pneumonia downtrended (1.66/1,000 vs. 8.74/1,000 ventilator days, p = 0.07).

CONCLUSION

Two years after implementation of a QRC, sustainable high rates of compliance with clinically relevant preventative measures in a SICU was demonstrated with minimal fading of clinically relevant outcomes.

Provision of critical care services for the obstetric population

Management of the peripartum patient is a challenging aspect of critical care that requires consideration of both the physiological changes associated with pregnancy as well as the well-being of the foetus. In the UK, for every maternal death, approximately 118 near-miss events or severe acute maternal morbidities (SAMMs) occur. While a dedicated anaesthetic cover is usually provided on larger labour wards in the UK and US, a close communication with intensive care and other medical specialties must still be maintained. Medical outreach teams and early warning scores may help facilitate the early identification of clinical deterioration and prompt treatment. Ultimately level of care is allocated according to the clinical need, not the location, which may be a designated room, a normal labour room or a recovery area. Specialist obstetric units that provide high-dependency care facilities show lower rates of maternal transfer to critical care units and improved continuity of care before and after labour. The benefits of obstetric high-dependency units (HDUs) are likely to be determined by a number of logistic aspects of the hospital organisation, including hospital size and available resources. There remains a striking contrast in the burden of maternal mortality and morbidity and intensive care unit (ICU) resources between high- and low-income countries. The countries with the highest maternal mortality rates have the lowest number of ICU beds per capita. In under-resourced countries, patients admitted to ICUs tend to have higher illness severity scores, suggesting delayed admission to the ICU. The appropriate training of midwives is essential for successful HDUs located within labour wards.

A cough algorithm for chronic cough in children: a multicenter, randomized controlled study

OBJECTIVES

The goals of this study were to: (1) determine if management according to a standardized clinical management pathway/algorithm (compared with usual treatment) improves clinical outcomes by 6 weeks; and (2) assess the reliability and validity of a standardized clinical management pathway for chronic cough in children.

METHODS

A total of 272 children (mean ± SD age: 4.5 ± 3.7 years) were enrolled in a pragmatic, multicenter, randomized controlled trial in 5 Australian centers. Children were randomly allocated to 1 of 2 arms: (1) early review and use of cough algorithm ("early-arm"); or (2) usual care until review and use of cough algorithm ("delayed-arm"). The primary outcomes were proportion of children whose cough resolved and cough-specific quality of life scores at week 6. Secondary measures included cough duration postrandomization and the algorithm's reliability, validity, and feasibility.

RESULTS

Cough resolution (at week 6) was significantly more likely in the early-arm group compared with the delayed-arm group (absolute risk reduction: 24.7% [95% confidence interval: 13-35]). The difference between cough-specific quality of life scores at week 6 compared with baseline was significantly better in the early-arm group (mean difference between groups: 0.6 [95% confidence interval: 0.29-1.0]). Duration of cough postrandomization was significantly shorter in the early-arm group than in the delayed-arm group (P = .001). The cough algorithm was reliable (κ = 1 in key steps). Feasibility was demonstrated by the algorithm's validity (93%-100%) and efficacy (99.6%). Eighty-five percent of children had etiologies easily diagnosed in primary care.

CONCLUSIONS

Management of children with chronic cough, in accordance with a standardized algorithm, improves clinical outcomes irrespective of when it is implemented. Further testing of this standardized clinical algorithm in different settings is recommended.

Protocol-directed care in the ICU: making a future generation of intensivists less knowledgeable?

Expanded abstract

The way in which a physiotherapy service is structured can improve patient outcome from a surgical intensive care: a controlled clinical trial

Introduction

The physiological basis of physiotherapeutic interventions used in intensive care has been established. We must determine the optimal service approach that will result in improved patient outcome. The aim of this article is to report on the estimated effect of providing a physiotherapy service consisting of an exclusively allocated physiotherapist providing evidence-based/protocol care, compared with usual care on patient outcomes.

Methods

An exploratory, controlled, pragmatic, sequential-time-block clinical trial was conducted in the surgical unit of a tertiary hospital in South Africa. Protocol care (3 weeks) and usual care (3 weeks) was provided consecutively for two 6-week intervention periods. Each intervention period was followed by a washout period. The physiotherapy care provided was based on the unit admission date. Data were analyzed with Statistica in consultation with a statistician. Where indicated, relative risks with 95% confidence intervals (CIs) are reported. Significant differences between groups or across time are reported at the alpha level of 0.05. All reported P values are two-sided.

Results

Data of 193 admissions were analyzed. No difference was noted between the two patient groups at baseline. Patients admitted to the unit during protocol care were less likely to be intubated after unit admission (RR, 0.16; 95% CI, 0.07 to 0.71; RRR, 0.84; NNT, 5.02; P = 0.005) or to fail an extubation (RR, 0.23; 95% CI, 0.05 to 0.98; RRR, 0.77; NNT, 6.95; P = 0.04). The mean difference in the cumulative daily unit TISS-28 score during the two intervention periods was 1.99 (95% CI, 0.65 to 3.35) TISS-28 units (P = 0.04). Protocol-care patients were discharged from the hospital 4 days earlier than usual-care patients (P = 0.05). A tendency noted for more patients to reach independence in the transfers (P = 0.07) and mobility (P = 0.09) categories of the Barthel Index.

Conclusions

A physiotherapy service approach that includes an exclusively allocated physiotherapist providing evidence-based/protocol care that addresses pulmonary dysfunction and promotes early mobility improves patient outcome. This could be a more cost-effective service approach to care than is usual care. This information can now be considered by administrators in the management of scarce physiotherapy resources and by researchers in the planning of a multicenter randomized controlled trial.

Implementation of a protocol facilitates evidence-based physiotherapy practice in intensive care units

OBJECTIVES

To compare the physiotherapy service provided when therapists' decisions are guided by an evidence-based protocol with usual care (i.e. patient management based on therapists' clinical decisions).

DESIGN

Exploratory, controlled, pragmatic sequential time block clinical trial.

SETTING

Level 3 surgical unit in a tertiary hospital in South Africa.

PARTICIPANTS

All patients admitted consecutively to the surgical unit over a 3-month period were allocated to usual or protocol care based on date of admission.

INTERVENTIONS

Usual care was provided by clinicians from the hospital department, and non-specialised physiotherapists were appointed as locum tenens to provide evidence-based protocol care.

MAIN OUTCOME MEASURES

Patient waiting time, frequency of treatment sessions, tasks performed and adverse events.

RESULTS

During protocol-care periods, treatment sessions were provided more frequently (P<0.001) and with a shorter waiting period (P<0.001). It was more likely for a rehabilitation management option to be included in a treatment session during protocol-care periods (odds ratio 2.34, 95% confidence interval 1.66 to 3.43; P<0.001). No difference in the risk of an adverse event was found between protocol-care and usual-care periods (P=0.34).

CONCLUSIONS

Physiotherapy services provided in intensive care units (ICUs) when the decisions of non-specialised therapists are guided by an evidence-based protocol are safe, differ from usual care, and reflect international consensus on current best evidence for physiotherapy in ICUs. Non-specialised therapists can use this protocol to provide evidence-based physiotherapy services to their patients. Future trials are needed to establish whether or not this will improve patient outcome.

The anesthesia team of the future

PURPOSE OF REVIEW

This review is aimed at highlighting the recent developments and opportunities that are likely to impact the anesthesia team of the future.

RECENT FINDINGS

The anesthesia team of the future aims to provide well tolerated, efficient, and cost-effective perioperative care. Certified and subspecialty trained anesthesiologists lead a diverse team of care providers in increasingly dissimilar environments. The spread of electronic health record systems has been the basis for the development of clinical decision support applications that promise to integrate quality control, enhanced efficiency, research opportunities, and improved patient care in the perioperative period. Perioperative epidemiology is a likely area of growth within the field of anesthesiology ultimately enabling the anesthesia team to translate precise real-time information into improved outcome.

SUMMARY

The anesthesia team of the future will require the anesthesiologist to provide expertise across the entire domain of perioperative medicine. Meaningful decision support systems rely on accurate data analysis and incorporation of current clinical guidelines and recommendations.

Short people got no reason: gender, height, and disparities in the management of acute lung injury

Though the benefits of lung protective ventilation (LPV) in acute lung injury/acute respiratory distress syndrome (ALI/ARDS) have been known for more than a decade, widespread clinical adoption has been slow. Han and colleagues demonstrate that women with ALI/ARDS are less likely than men to receive LPV, though this disparity resolves when the analysis is adjusted for patient height. This analysis identifies patient height as a significant factor in predicting provider adherence with LPV guidelines, and illuminates why some disparities in intensive care exist and how they may be resolved via improved utilization of evidence-driven protocols.

Can a management pathway for chronic cough in children improve clinical outcomes: protocol for a multicentre evaluation

BACKGROUND

Chronic cough is common and is associated with significant economic and human costs. While cough can be a problematic symptom without serious consequences, it could also reflect a serious underlying illness. Evidence shows that the management of chronic cough in children needs to be improved. Our study tests the hypothesis that the management of chronic cough in children with an evidence-based management pathway is feasible and reliable, and improves clinical outcomes.

METHODS/DESIGN

We are conducting a multicentre randomised controlled trial based in respiratory clinics in 5 major Australian cities. Children (n = 250) fulfilling inclusion criteria (new patients with chronic cough) are randomised (allocation concealed) to the standardised clinical management pathway (specialist starts clinical pathway within 2 weeks) or usual care (existing care until review by specialist at 6 weeks). Cough diary, cough-specific quality of life (QOL) and generic QOL are collected at baseline and at 6, 10, 14, 26, and 52 weeks. Children are followed-up for 6 months after diagnosis and cough resolution (with at least monthly contact from study nurses). A random sample from each site will be independently examined to determine adherence to the pathway. Primary outcomes are group differences in QOL and proportion of children that are cough free at week 6.

DISCUSSION

The clinical management pathway is based on data from Cochrane Reviews combined with collective clinical experience (250 doctor years). This study will provide additional evidence on the optimal management of chronic cough in children.

A multidisciplinary protocol improves electrolyte replacement and its effectiveness

BACKGROUND

We implemented a multidisciplinary electrolyte replacement protocol in a tertiary referral center surgical intensive care unit. The purpose of this study was to evaluate its efficacy.

METHODS

This was a retrospective study. The electrolyte replacement protocol was designed for the replacement of potassium, magnesium, and phosphorous and was nurse driven. Data evaluated included patient demographics and details specific to electrolyte replacement. Univariate analyses were performed by using the Student t test and the Fisher exact test. A P value of <.05 was considered significant.

RESULTS

After implementation of the protocol, overall electrolyte replacement improved from 70% to 79% (P = .03), and its overall effectiveness increased from 50% to 65% (P = .01). Individual electrolyte replacement, effectiveness, and dosing varied.

CONCLUSIONS

The implementation of a multidisciplinary electrolyte replacement protocol in a tertiary referral center surgical intensive care unit significantly improved both overall electrolyte replacement and its effectiveness.

Implementation of the enteral nutrition practice recommendations

In developing the evidence-based Enteral Nutrition Practice Recommendations, the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) formed a task force to address the many aspects of safety in the delivery and provision of enteral nutrition support. This recently published document provides healthcare professionals with recommendations that are derived from evidence-based practice. The development and use of clinical practice guidelines (CPGs) is a recent, significant contribution for the dissemination of evidence-based medicine. This involves the review of scientific literature along with clinical skill and knowledge to generate specific recommendations assisting healthcare providers and patients with decisions regarding appropriate healthcare. A primary opportunity to improve patient outcomes will come from the effective delivery of existing therapies rather than from the new development of treatment modalities. Compliance with CPGs is challenging because it depends on a variety of factors. Both general and specific strategies have been devised with the expansion of the new discipline of implementation science. The high degree of evidence now available in medicine gives clinicians more opportunity to improve patient outcomes and quality of care. It remains for clinicians to evaluate their institutional mission and goals, and to investigate those CPGs appropriate to improve patient care in that setting.

Multicenter implementation of a consensus-developed, evidence-based, spontaneous breathing trial protocol

OBJECTIVE

Evidence-based practice recommendations abound, but implementation is often unstructured and poorly audited. We assessed the ability of a peer network to implement an evidence-based best practice protocol and to measure patient outcomes.

DESIGN

Consensus definition of spontaneous breathing trial followed by implementation in eight academic medical centers.

SETTING

Six medical, two surgical, and two combined medical/surgical adult intensive care units among eight academic medical centers.

STUDY POPULATION

Patients initiating mechanical ventilation through an endotracheal tube during a 12-wk interval formed the study population.

INTERVENTIONS

Adoption and implementation of a common spontaneous breathing trial protocol across multiple intensive care units.

MEASUREMENTS AND MAIN RESULTS

Seven hundred five patients had 3,486 safety screens for conducting a spontaneous breathing trial; 2072 (59%) patients failed the safety screen. Another 379 (11%) patients failed a 2-min tolerance screen and 1,122 (34%) patients had a full 30-120 min spontaneous breathing trial performed. Seventy percent of eligible patients were enrolled. Only 55% of passing spontaneous breathing trials resulted in liberation from mechanical ventilatory support before another spontaneous breathing trial was performed.

CONCLUSIONS

Peer networks can be effective in promoting and implementing evidence-based best practices. Implementation of a best practice (spontaneous breathing trial) may be necessary for, but by itself insufficient to achieve, consistent and timely liberation from ventilator support.

Non-compliance with a postmastectomy radiotherapy guideline: decision tree and cause analysis

BACKGROUND

The guideline for postmastectomy radiotherapy (PMRT), which is prescribed to reduce recurrence of breast cancer in the chest wall and improve overall survival, is not always followed. Identifying and extracting important patterns of non-compliance are crucial in maintaining the quality of care in Oncology.

METHODS

Analysis of 759 patients with malignant breast cancer using decision tree induction (DTI) found patterns of non-compliance with the guideline. The PMRT guideline was used to separate cases according to the recommendation to receive or not receive PMRT. The two groups of patients were analyzed separately. Resulting patterns were transformed into rules that were then compared with the reasons that were extracted by manual inspection of records for the non-compliant cases.

RESULTS

Analyzing patients in the group who should receive PMRT according to the guideline did not result in a robust decision tree. However, classification of the other group, patients who should not receive PMRT treatment according to the guideline, resulted in a tree with nine leaves and three of them were representing non-compliance with the guideline. In a comparison between rules resulting from these three non-compliant patterns and manual inspection of patient records, the following was found: In the decision tree, presence of perigland growth is the most important variable followed by number of malignantly invaded lymph nodes and level of Progesterone receptor. DNA index, age, size of the tumor and level of Estrogen receptor are also involved but with less importance. From manual inspection of the cases, the most frequent pattern for non-compliance is age above the threshold followed by near cut-off values for risk factors and unknown reasons.

CONCLUSION

Comparison of patterns of non-compliance acquired from data mining and manual inspection of patient records demonstrates that not all of the non-compliances are repetitive or important. There are some overlaps between important variables acquired from manual inspection of patient records and data mining but they are not identical. Data mining can highlight non-compliance patterns valuable for guideline authors and for medical audit. Improving guidelines by using feedback from data mining can improve the quality of care in oncology.

Sedation practice: is it time to wake up and embrace change?

Recommendations for sedation regimes in the intensive care unit (ICU) have evolved over the last decade based on findings that relate the clinical approach to improved patient outcomes. Martin and co-workers conducted two surveys into German sedation practice covering the time period during which these changes occurred and as such provide an insight into how these recommendations are being incorporated into everyday clinical practice.

Admission Time and Outcomes of Patients in A Medical Intensive Care Unit

Studies have shown that weekend or night admissions to intensive care units (ICUs) are associated with increased mortality in critically ill patients. Our study aimed to evaluate the effects of admission time and day on patient outcomes in a medical ICU equipped with patient management guide-lines, and staffed by intensivists on call for 24 hours, who led the morning rounds on all days of the week but did not stay in-house overnight. The study enrolled 611 consecutive patients admitted to a 26-bed medical ICU in a university hospital during a 7-month period. We divided them into two groups, which we labeled as "office hours" (08:00-18:00 on weekdays) and "non-office hours" (18:00-08:00 on weekdays, and all times on weekends) according to their ICU admission times. The clinical outcomes were compared between the groups. The effects of admission on weekends, at night, and various days of the week on hospital mortality were also evaluated. Our results showed that there were no significant differences in ICU and hospital mortalities between patients admitted during office hours and those admitted during non-office hours (27.2% vs. 27.4%, p = 1.000; 38.9% vs. 37.6%, p = 0.798). The ICU length of stay, ICU-free time within 21 days, and length of stay in the hospital were also comparable in both groups. Among the 392 patients requiring mechanical ventilation, the ventilator outcomes were not significantly different between those in the office-hour group and the non-office-hour group. Multivariate logistic regression analyses showed that the adjusted odds of hospital mortality were not significantly higher for patients admitted to our ICU on weekends, at night, or on any days of the week. In conclusion, our results showed that non-office-hour admissions to our medical ICU were not associated with poorer ICU, hospital, and ventilator outcomes, compared with office-hour admissions. Neither were time of day and day of the week admissions to our ICU associated with significant differences in hospital mortality.

Implementing an intravenous insulin infusion protocol in the intensive care unit

PURPOSE

The implementation of three different insulin protocols in intensive care unit (ICU) settings in two community hospitals and one academic hospital is described.

SUMMARY

Each institution possessed a commitment to improve the existing insulin protocols in order to achieve tighter glycemic control for ICU patients. Studies have shown that the maintenance of tight glycemic control provides improved patient outcomes. Obstacles to implementation of the insulin protocols at the institutions were increased staff workload, difficulties in interpreting algorithms, and lack of perceived benefit. In comparing details of the insulin protocols at the academic and community hospitals, it was found that differences were influenced by the type of institution. The differences among the institutions in the implementation of the protocols included the initial physician response to the protocol, the details of each protocol, nursing staff autonomy, and the involvement of the nursing staff in early protocol development. All three institutions had a dedicated pharmacist in the ICU who committed time toward insulin protocol implementation. For an increased likelihood of successful insulin protocol implementation, a full-time dedicated ICU pharmacist should be assigned to participate on multidisciplinary rounds, provide nursing support and education, and collect process measures to monitor and improve the protocol.

CONCLUSION

The i.v. insulin infusion protocols developed and implemented in the ICUs at three institutions successfully achieved acceptance and compliance by physicians and nurses. The factors attributed to the success were multidisciplinary involvement, the continuous education of nursing staff, the vigilant involvement of a pharmacist, and flexibility in revising the protocol.

Hyperglycemia in the Critically Ill Patient

Hyperglycemia and insulin resistance are common among critically ill patients and occur in patients with or without a history of diabetes mellitus. All patients undergoing critical illness are at risk for stress-induced hyperglycemia. Some patients may be at greater risk for hyperglycemia than others when considering underlying disease states and iatrogenic factors. Many recent studies demonstrate that tight glucose control can decrease morbidity and mortality associated with critical illness. This article reviews the pathophysiology behind stress-induced hyperglycemia, the evidence to support tight glycemic control, and the importance of an intensive insulin therapy protocol to standardize treatment among critical care patients.

Protocol-driven vs. physician-driven electrolyte replacement in adult critically ill patients

BACKGROUND

The intensive care unit is a dynamic environment, where high numbers of patients cared for by health care workers of different experiences and backgrounds might result in great variability in patient care. Protocol-driven interventions may facilitate timely and uniform care of common problems, like electrolyte disturbances. We prospectively compared protocol-driven (PRD) vs. physician-driven (PHD) electrolyte replacement in adult critically ill patients.

PATIENTS AND METHODS

In the first month of the two-month study, potassium, magnesium, and phosphate levels were checked by a physician before ordering replacement (PHD replacement period). Over the second month, ICU nurses proceeded with replacement according to the protocol (PRD replacement period). We collected demographic data, admission diagnosis, number of potassium, magnesium, and phosphate levels done per day, number of low levels per day, number of replacements per day, time between availability of results to ordering replacement, time to starting replacement, post-replacement levels, serum creatinine, replacement dose, arrhythmias and replacement route.

RESULTS

During the PHD replacement period, 43 patients meeting the inclusion criteria were admitted to the ICU, while 44 were admitted during the PRD month. The mean time (minutes) from identifying results to replacement of potassium, phosphate and magnesium was significantly longer with PHD replacement compared with PRD replacement (161, 187, and 189 minutes vs. 19, 26, and 19 minutes) (P<0.0001). The number of replacements needed and not given was also significantly lower in the PRD replacement period compared with the PHD replacement period (2, 4, and 0 compared with 9, 6 and 0) (P<0.05). No patients had high post-replacement serum concentrations of potassium, phosphate or magnesium.

CONCLUSIONS

This study shows that a protocol-driven replacement strategy for potassium, magnesium and phosphate is more efficient and as safe as a physician-driven replacement strategy.

Use of a computerized guideline for glucose regulation in the intensive care unit improved both guideline adherence and glucose regulation

OBJECTIVE

To measure the impact of a computerized guideline for glucose regulation in an ICU.

DESIGN

A randomized, controlled trial with an off-on-off design.

METHODS

We implemented a glucose regulation guideline in an intensive care unit in paper form during the first study period. During the second period, the guideline was randomly applied in either paper or computerized form. In the third period, the guideline was available only in paper form.

MEASUREMENTS AND RESULTS

We analyzed data for 484 patients. During the intervention period, the control group included 54 patients and the computerized intervention group included 66 patients. The two guideline-related outcome measures consisted of compliance with: (a) glucose measurement timing recommendations and (b) insulin dose advice. We measured clinical impact as the proportion of time that glucose levels fell within target range. In the first (paper-based) study period, 29.0% of samples occurred with optimal timing; during the second period, this increased to 35.5% for paper-based and to 40.2% for computerized protocols. The third study period timeliness scores reverted to the first period rates. Late (suboptimal) sampling occurred for 66% of glucose measurements in the first study period, for 42% of paper-based and 28% of computer-based protocol samples in the second period, and for 50.0% of samples in the third study period. In the first study period, insulin-dosing guideline compliance was 56.3%; in the second period, it was 64.2% for paper-based and 77.3% for computer-based protocols, and it fell to 42.4% in the third period. For the second study period, the time that a patient's glucose values fell within target range improved for both the control (52.9%) and the computerized groups (54.2%) compared with the first study period (44.3%) and the third period (42.3%).

CONCLUSION

Implementing a computerized version of a guideline significantly improved timeliness of measurements and glucose level regulation for critically ill patients compared with implementing a paper-based version of the guideline.

Insulin resistance and hyperglycemia in critical illness: role of insulin in glycemic control

Alterations in glucose metabolism, including hyperglycemia associated with insulin resistance, occur in critical illness. Acutely, such alterations result from normal, adaptive activation of endocrine responses, including increased release of catecholamines, cortisol, and glucagon and a reduced glucose uptake capacity. In prolonged critical illness, neuroendocrine changes lead to more extensive metabolic changes that may be associated with development of complications and poor prognosis. Until recently, hyperglycemia was not routinely controlled in intensive care units, except among patients with known diabetes mellitus. Studies have demonstrated that glycemic management in postmyocardial infarction in patients with diabetes is an effective practice. Recent investigation has extended this to demonstrate reduced morbidity and mortality in a surgical critically ill population with and without diabetes mellitus in later phases of critical illness. Although the mechanisms for improved patient outcomes need to be established, this novel approach to management of hyperglycemia in critical illness is a new and important concept for those working in critical care. This article reviews alterations in glucose metabolism which occur in critically ill patients and discusses potential mechanisms and mediators (e.g., hormones, cytokines) that may play a key role in hyperglycemia and insulin resistance during acute and prolonged phases of severe illness. The article addresses the application of insulin protocols and exogenous regulation of glucose concentration in critical illness based on a review of recent intervention studies.

Guidelines in the intensive care unit

The recent movement toward standardization of critical care practice is associated with a growth in the use of guidelines and protocols. Although complex, the process of guideline development, implementation, evaluation, and maintenance can be systematic. Guideline implementation can improve the processes and outcomes of care; however, guideline adherence represents a major challenge to their success. The quality of the growing number of practice guidelines in critical care is important to assess and several useful instruments are available for this purpose.

Insulin therapy for the critically ill patient

The risk of mortality or significant morbidity is high among critically ill patients who are treated in the intensive care unit (ICU) for > 5 days. These patients are susceptible to sepsis, excessive inflammation, critical illness polyneuropathy, and multiple organ failure, the latter often being the cause of death. Most intensive care patients, even those who did not previously suffer from diabetes, are hyperglycemic, which is presumed to reflect an adaptive development of insulin resistance. In the K.U. Leuven study it was hypothesized that hyperglycemia is not a beneficial adaptation to severe illness but rather predisposes patients to many of the typical intensive care complications--prolonged intensive care dependence and death. The effects of intensive insulin therapy to maintain normoglycemia during critical illness were studied in a large group (N = 1548) of ventilated, surgical ICU patients. An algorithm was proposed for implementing this procedure. The randomly assigned intensive insulin therapy group received insulin infusion tailored to control blood glucose (BG) levels in the range 80-110 mg/dL, whereas the conventional treatment group received insulin only when glucose levels exceeded 200 mg/dL, and in that event were maintained in a target range of 180-200 mg/dL. Intensive insulin therapy induced a 43% reduction of intensive care mortality risk (P = 0.036 after correction for interim analyses) and a 34% reduction of hospital mortality (P = 0.005). A reduced risk of severe infections by 46% (P = 0.003) was associated with a 35% reduction in prolonged (> 10 d) requirement for antibiotic therapy (P < 0.001). In addition, excessive inflammation was prevented. Logistic regression analysis indicated that control of BG levels, rather than insulin administration itself, likely explains the observed clinical benefits. Use of insulin infusion to maintain normoglycemia using a titration algorithm, at least in populations similar to those in the Leuven study, improves outcome. Further data are needed to establish the applicability of this strategy to other patient groups, such as those in a medical ICU and in general hospital care.
