Pain assessment of the adult sedated and ventilated patients in the intensive care setting: A scoping review

BACKGROUND

Pain is frequently encountered in the intensive care setting. Given the impact of pain assessment on patient outcomes and length of hospital stay, studies have been conducted to validate tools, establish guidelines and cast light on practices relating to pain assessment.

OBJECTIVE

To examine the extent, range and nature of the evidence around pain assessment practices in adult patients who cannot self-report pain in the intensive care setting and summarise the findings from a heterogenous body of evidence to aid in the planning and the conduct of future research and management of patient care. The specific patient cohort studied was the sedated/ ventilated patient within the intensive care setting.

DESIGN

A scoping review protocol utilised the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping review checklist (PRISMA-ScR).

METHODS

The review comprised of five phases: identifying the research question, identifying relevant studies, study selection, charting the data and collating, summarizing, and reporting the results. Databases were systematically searched from January to April 2020. Databases included were Scopus, Web of Science, Medline via Ovid, CINAHL COMPLETE via EBSCO host, Health Source and PUBMED. Limits were applied on dates (2000 to current), language (English), subject (human) and age (adult). Key words used were "pain", "assessment", "measurement", "tools", "instruments", "practices", "sedated", "ventilated", "adult". A hand search technique was used to search citations within articles. Database alerts were set to apprise the availability of research articles pertaining to pain assessment practices in the intensive care setting.

RESULTS

The review uncovered literature categorised under five general themes: behaviour pain assessment tools, pain assessment guidelines, position statements and quality improvement projects, enablers and barriers to pain assessment, and evidence appertaining to actual practices. Behaviour pain assessment tools are the benchmark for pain assessment of sedated and ventilated patients. The reliability and validity of physiologic parameters to assess pain is yet to be determined. Issues of compliance with pain assessment guidelines and tools exist and impact on practices. In some countries like Australia, there is a dearth of information regarding the prevalence and characteristics of patients receiving analgesia, type of analgesia used, pain assessment practices and the process of recording pain management. In general, pain assessment varies across different intensive care settings and lacks consistency.

CONCLUSION

Research on pain assessment practices requires further investigation to explore the causative mechanisms that contribute to poor compliance with established pain management guidelines. The protocol of this review was registered with Open Science Framework (https://osf.io/25a6) Tweetable abstract: Pain assessment in intensive care settings lacks consistency. New information is needed to understand the causative mechanisms underpinning poor compliance with guidelines.

Ventilation bundle compliance in two Australian intensive care units: An observational study

Background

The ventilation bundle has been used in adult intensive care units to decrease harm and improve quality of care for mechanically ventilated patients. The ventilation bundle focuses on prevention of specific complications of mechanical ventilation; ventilator-associated pneumonia, sepsis, barotrauma, pulmonary oedema, pulmonary embolism, and acute respiratory distress syndrome. The Institute for Healthcare Improvement ventilation bundle consists of five structured evidence-based interventions: head of the bed elevation at 30–45°; daily sedation interruptions and assessment of readiness to extubate; peptic ulcer prophylaxis; deep vein thrombosis prophylaxis; and daily oral care with chlorhexidine.

Objectives

The objective of the study was to evaluate the use of the ventilation bundle in two intensive care units in Victoria, Australia.

Methods

This is a 3-month prospective observational study in two intensive care units. Patient medical records were reviewed on days 3, 4, and 5 of mechanical ventilation using a prevalidated ventilation bundle checklist.

Results

A total of 96 critically ill patients required mechanical ventilation for more than 2 d. Patients had a mean age of 64.50 y (standard deviation = 14.89), with an Acute Physiology, Age, Chronic Health Evaluation (APACHE) III mean score of 79.27 (standard deviation = 27.11). The mean ventilation bundle compliance rate was 88.3% on the three consecutive mechanical ventilation days (day 3 = 79.4%, day 4 = 91.1%, and day 5 = 96.7%). There was a statistically significant difference in the mean APACHE III score between patients who had head of bed elevation and those without head of bed elevation, on days 3 (p = <0.001) and 4 (p = 0.007).

Conclusion

The ventilation bundle elements were used in Australian intensive care units. The likelihood of having all ventilation bundle elements on day 3 was low if the patient's APACHE III score was high. However, the ventilation bundle compliance rate increased with mechanical ventilation days.

Impact of a Sequential Intervention on Albumin Utilization in Critical Care

OBJECTIVES

Literature generally finds no advantages in mortality risk for albumin over cheaper alternatives in many settings. Few studies have combined financial and nonfinancial strategies to reduce albumin overuse. We evaluated the effect of a sequential multifaceted intervention on decreasing albumin use in ICU and explore the effects of different strategies.

DESIGN

Prospective prepost cohort study.

SETTING

Eight ICUs at two hospitals in an academic healthcare system.

PATIENTS

Adult patients admitted to study ICUs from September 2011 to August 2014 (n = 22,004).

INTERVENTIONS

Over 2 years, providers in study ICUs participated in an intervention to reduce albumin use involving monthly feedback and explicit financial incentives in the first year and internal guidelines and order process changes in the second year.

MEASUREMENTS AND MAIN RESULTS

Outcomes measured were albumin orders per ICU admission, direct albumin costs, and mortality. Mean (SD) utilization decreased 37% from 2.7 orders (6.8) per admission during the baseline to 1.7 orders (4.6) during the intervention (p < 0.001). Regression analysis revealed that the intervention was independently associated with 0.9 fewer orders per admission, a 42% relative decrease. This adjusted effect consisted of an 18% reduction in the probability of using any albumin (p < 0.001) and a 29% reduction in the number of orders per admission among patients receiving any (p < 0.001). Secondary analysis revealed that probability reductions were concurrent with internal guidelines and order process modification while reductions in quantity occurred largely during the financial incentives and feedback period. Estimated cost savings totaled $2.5M during the 2-year intervention. There was no significant difference in ICU or hospital mortality between baseline and intervention.

CONCLUSIONS

A sequential intervention achieved significant reductions in ICU albumin use and cost savings without changes in patient outcomes, supporting the combination of financial and nonfinancial strategies to align providers with evidence-based practices.

Why We Belong - Exploring Membership of Healthcare Professionals in an Intensive Care Virtual Community Via Online Focus Groups: Rationale and Protocol

Background

Many current challenges of evidence-based practice are related to ineffective social networks among health care professionals. Opportunities exist for multidisciplinary virtual communities to transcend professional and organizational boundaries and facilitate important knowledge transfer. Although health care professionals have been using the Internet to form virtual communities for many years, little is known regarding “why” they join, as most research has focused on the perspective of “posters,” who form a minority of members.

Objective

Our aim was to develop a comprehensive understanding of why health care professionals belong to a virtual community (VC).

Methods

A qualitative approach will be used to explore why health care professionals belong to an intensive care practice-based VC, established since 2003. Three asynchronous online focus groups will be convened using a closed secure discussion forum. Participants will be recruited directly by sending emails to the VC and a Google form used to collect consent and participant demographics. Participants will be stratified by their online posting behaviors between September 1, 2012, and August 31, 2014: (1) more than 5 posts, (2) 1-5 posts, or (3) no posts. A question guide will be used to guide participant discussion. A moderation approach based on the principles of focus group method and e-moderation has been developed. The main source of data will be discussion threads, supported by a research diary and field notes. Data analysis will be undertaken using a thematic approach and framed by the Diffusion of Innovation theory. NVivo software will be used to support analyses.

Results

At the time of writing, 29 participants agreed to participate (Focus Group 1: n=4; Focus Group 2: n=16; Focus Group 3: n=9) and data collection was complete.

Conclusions

This study will contribute to a growing body of research on the use of social media in professional health care settings. Specifically, we hope results will demonstrate an enhancement of health care professionals’ social networks and how VCs may improve knowledge distribution and patient care outcomes. Additionally, the study will contribute to research methods development in this area by detailing approaches to understand the effectiveness of online focus groups as a data collection method for qualitative research methods.

Using Incentives to Improve Resource Utilization: A Quasi-Experimental Evaluation of an ICU Quality Improvement Program

OBJECTIVES

Healthcare systems strive to provide quality care at lower cost. Arterial blood gas testing, chest radiographs, and RBC transfusions provide an important example of opportunities to reduce excess resource utilization within the ICU. We describe the effect of a multifaceted quality improvement program designed to decrease the avoidable arterial blood gases, chest radiographs, and RBC utilization on utilization of these resources and patient outcomes.

DESIGN

Prospective pre-post cohort study.

SETTING

Seven ICUs in an academic healthcare system.

PATIENTS

All adult ICU patients admitted to study ICUs during consecutive baseline (n = 7,357), intervention (n = 7,553), and follow-up (n = 7,657) years between September 2010 and August 2013.

INTERVENTIONS

A multifaceted quality improvement program including provider education, audit and feedback, and unit-based provider financial incentives targeting arterial blood gas, chest radiograph, and RBC utilization.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was the number of orders for arterial blood gases, chest radiographs, and RBCs per patient. Compared with the baseline period, unadjusted arterial blood gas, chest radiograph, and RBC utilization in the intervention period was reduced by 42%, 26%, and 17%, respectively (p < 0.01). After adjusting for potentially relevant patient factors, the intervention was associated with 128 fewer arterial blood gases, 73 fewer chest radiographs, and 16 fewer RBCs per 100 patients (p < 0.01). This effect was durable during the follow-up year. This reduction yielded an approximate net savings of $1.5 M in direct costs over the intervention and follow-up years after accounting for the direct costs of the program. Unadjusted hospital mortality decreased from 7% in the baseline period to 5.2% in the intervention period (p < 0.01). This reduction remained significant after adjusting for patient factors (odds ratio = 0.43; p < 0.01).

CONCLUSIONS

Implementation of a multifaceted quality improvement program including financial incentives was associated with significant improvements in resource utilization. Our findings provide evidence supporting the safety, effectiveness, and sustainability of incentive-based quality improvement interventions.

Testing the implementation of an electronic process-of-care checklist for use during morning medical rounds in a tertiary intensive care unit: a prospective before-after study

Background

To improve the delivery of important care processes in the ICU, morning ward round checklists have been implemented in a number of intensive care units (ICUs) internationally. Good quality evidence supporting their use as clinical support tools is lacking. With increased use of technology in clinical settings, integration of such tools into current work practices can be a challenge and requires evaluation. Having completed preliminary work revealing variations in practice and evidence supporting the construct validity of a process-of-care checklist, the need to develop, test and further validate an e(lectronic)-checklist in an ICU was identified.

Methods

A prospective, before–after study was conducted in a 19-bed general ICU within a tertiary hospital. Data collection occurred during baseline and intervention periods for 6 weeks each, with education and training conducted over a 4-week period prior to intervention. The e-checklist was used at baseline by ICU research nurses conducting post-ward round audits. During intervention, senior medical staff completed the e-checklist after patient assessments during the morning ward rounds, and research staff conducted post-ward round audits for validity testing (via concordance measurement). To examine changes in compliance over time, checklist-level data were analysed using generalised estimating equations that factored in confounding variables, and statistical process control charts were used to evaluate unit-level data. Established measures of concordance were used to evaluate e-checklist validity.

Results

Compliance with each care component improved significantly over time; the largest improvement was for pain management (42% increase; adjusted odds ratio = 23, p < 0.001), followed by glucose management (22% increase, p < 0.001) and head-of-bed elevation (19% increase, p < 0.001), both with odds ratios greater than 10. Most detected omissions were corrected by the following day. Control charts illustrated reduced variability in care compliance over time. There was good concordance between physician and auditor e-checklist responses; seven out of nine cares had kappa values above 0.8.

Conclusion

Improvements in the delivery of essential daily care processes were evidenced after the introduction of an e-checklist to the morning ward rounds in an ICU. High levels of agreement between physician and independent audit responses lend support to the validity of the e-checklist.

ICU director data: using data to assess value, inform local change, and relate to the external world

Improving value within critical care remains a priority because it represents a significant portion of health-care spending, faces high rates of adverse events, and inconsistently delivers evidence-based practices. ICU directors are increasingly required to understand all aspects of the value provided by their units to inform local improvement efforts and relate effectively to external parties. A clear understanding of the overall process of measuring quality and value as well as the strengths, limitations, and potential application of individual metrics is critical to supporting this charge. In this review, we provide a conceptual framework for understanding value metrics, describe an approach to developing a value measurement program, and summarize common metrics to characterize ICU value. We first summarize how ICU value can be represented as a function of outcomes and costs. We expand this equation and relate it to both the classic structure-process-outcome framework for quality assessment and the Institute of Medicine's six aims of health care. We then describe how ICU leaders can develop their own value measurement process by identifying target areas, selecting appropriate measures, acquiring the necessary data, analyzing the data, and disseminating the findings. Within this measurement process, we summarize common metrics that can be used to characterize ICU value. As health care, in general, and critical care, in particular, changes and data become more available, it is increasingly important for ICU leaders to understand how to effectively acquire, evaluate, and apply data to improve the value of care provided to patients.

Comparing mortality among adult, general intensive care units in England with varying intensivist cover patterns: a retrospective cohort study

Introduction

Research has demonstrated that intensivist-led care of the critically ill is associated with reduced intensive care unit (ICU) and hospital mortality. The objective of this study was to evaluate whether a relation exists between intensivist cover pattern (for example, number of days of continuous cover) and patient outcomes among adult general ICUs in England.

Methods

We conducted a retrospective cohort study by using data from a pooled case mix and outcome database of adult general critical care units participating in the Intensive Care National Audit & Research Centre (ICNARC) Case Mix Programme. Consecutive admissions to participating units for the years 2010 to 2011 were linked to a survey of intensivist cover practices. Our primary outcome of interest was mortality at ultimate discharge from acute-care hospital.

Results

The analysis included 80,122 patients admitted to 130 ICUs in 128 hospitals. Multivariable logistic regression analysis was used to assess the relation between intensivist cover patterns (days of continuous cover, grade of physician staffing at nighttime, and frequency of daily handovers) and acute hospital mortality, adjusting for patient case mix. No relation was seen between days of continuous cover by a single intensivist or grade of physician staffing at nighttime and acute hospital mortality. Acute hospital mortality and ICU length of stay were not associated with intensivist characteristics, intensivist full-time equivalents per bed, or years of clinical experience. Intensivist participation in handover was associated with increased mortality (odds ratio, 1.27; 95% confidence interval, 1.04 to 1.55); however, only nine units reported no intensivist participation.

Conclusions

We found no relation between days of continuous cover by a single intensivist or grade of physician staffing at nighttime and patient outcomes in adult, general ICUs in England. Intensivist participation in handover was associated with increased mortality; further research to confirm or refute this finding is required.

Feasibility and inter-rater reliability of the ICU Mobility Scale

OBJECTIVES

The objectives of this study were to develop a scale for measuring the highest level of mobility in adult ICU patients and to assess its feasibility and inter-rater reliability.

BACKGROUND

Growing evidence supports the feasibility, safety and efficacy of early mobilization in the intensive care unit (ICU). However, there are no adequately validated tools to quickly, easily, and reliably describe the mobility milestones of adult patients in ICU. Identifying or developing such a tool is a priority for evaluating mobility and rehabilitation activities for research and clinical care purposes.

METHODS

This study was performed at two ICUs in Australia. Thirty ICU nursing, and physiotherapy staff assessed the feasibility of the 'ICU Mobility Scale' (IMS) using a 10-item questionnaire. The inter-rater reliability of the IMS was assessed by 2 junior physical therapists, 2 senior physical therapists, and 16 nursing staff in 100 consecutive medical, surgical or trauma ICU patients.

RESULTS

An 11 point IMS scale was developed based on multidisciplinary input. Participating clinicians reported that the scale was clear, with 95% of respondents reporting that it took <1 min to complete. The junior and senior physical therapists showed the highest inter-rater reliability with a weighted Kappa (95% confidence interval) of 0.83 (0.76-0.90), while the senior physical therapists and nurses and the junior physical therapists and nurses had a weighted Kappa of 0.72 (0.61-0.83) and 0.69 (0.56-0.81) respectively.

CONCLUSION

The IMS is a feasible tool with strong inter-rater reliability for measuring the maximum level of mobility of adult patients in the ICU.

Developing content for a process-of-care checklist for use in intensive care units: a dual-method approach to establishing construct validity

Background

In the intensive care unit (ICU), checklists can be used to support the delivery of quality and consistent clinical care. While studies have reported important benefits for clinical checklists in this context, lack of formal validity testing in the literature prompted the study aim; to develop relevant ‘process-of-care’ checklist statements, using rigorously applied and reported methods that were clear, concise and reflective of the current evidence base. These statements will be sufficiently instructive for use by physicians during ICU clinical rounds.

Methods

A dual-method approach was utilized; semi-structured interviews with local clinicians; and rounds of surveys to an expert Delphi panel. The interviews helped determine checklist item inclusion/exclusion prior to the first round Delphi survey. The panel for the modified-Delphi technique consisted of local intensivists and a state-wide ICU quality committee. Minimum standards for consensus agreement were set prior to the distribution of questionnaires, and rounds of surveys continued until consensus was achieved.

Results

A number of important issues such as overlap with other initiatives were identified in interviews with clinicians and integrated into the Delphi questionnaire, but no additional checklist items were suggested, demonstrating adequate checklist coverage sourced from the literature. These items were verified by local clinicians as being relevant to ICU and important elements of care that required checking during ward rounds. Two rounds of Delphi surveys were required to reach consensus on nine checklist statements: nutrition, pain management, sedation, deep vein thrombosis and stress ulcer prevention, head-of-bed elevation, blood glucose levels, readiness to extubate, and medications.

Conclusions

Statements were developed as the most clear, concise, evidence-informed and instructive statements for use during clinical rounds in an ICU. Initial evidence in support of the checklist’s construct validity was established prior to further prospective evaluation in the same ICU.

Validating a process-of-care checklist for intensive care units

Early evidence suggests that checklists are one way of ensuring required processes of care are delivered to intensive care unit patients. Evidence to date however, has not explicitly detailed methods of checklist validation in these settings. This study aimed to test the validity of a 'process-of-care' checklist for measuring and ensuring daily care delivery in an intensive care unit. A retrospective audit of a random selection of patient medical records was undertaken to compare with checklist data completed during the same time frame. Documentation in the patients' medical records was used as a proxy measure for actual completion of care. A specific audit tool extracted information from both the checklist and the medical record on the following processes of care: nutrition, weaning from ventilation, pain, glucose control, sit out of bed, bowel management, deep vein thrombosis and stress ulcer prophylaxis. These two data sources were compared using the Spearman's rho correlation coefficient. The two forms of documentation were significantly correlated (P=0.01) for all but one of the checklist items (pain). Findings provided support for the concurrent validity of an intensive care unit process-of-care checklist. Further research is required for checklist validity and reliability testing prior to, or in conjunction with, a planned prospective intervention study.
