Abstract

AKI is a global concern with a high incidence among patients across acute care settings. AKI is associated with significant clinical consequences and increased health care costs. Preventive measures, as well as rapid identification of AKI, have been shown to improve outcomes in small studies. Providing high-quality care for patients with AKI or those at risk of AKI occurs across a continuum that starts at the community level and continues in the emergency department, hospital setting, and after discharge from inpatient care. Improving the quality of care provided to these patients, plausibly mitigating the cost of care and improving short- and long-term outcomes, are goals that have not been universally achieved. Therefore, understanding how the management of AKI may be amenable to quality improvement programs is needed. Recognizing this gap in knowledge, the 22nd Acute Disease Quality Initiative meeting was convened to discuss the evidence, provide recommendations, and highlight future directions for AKI-related quality measures and care processes. Using a modified Delphi process, an international group of experts including physicians, a nurse practitioner, and pharmacists provided a framework for current and future quality improvement projects in the area of AKI. Where possible, best practices in the prevention, identification, and care of the patient with AKI were identified and highlighted. This article provides a summary of the key messages and recommendations of the group, with an aim to equip and encourage health care providers to establish quality care delivery for patients with AKI and to measure key quality indicators.

Introduction

AKI is a common complication of acute illnesses with a substantial impact on clinical outcomes and health care costs (1–3). Literature highlights that AKI and its progression could be prevented in some circumstances, and its consequences could be mitigated by timely and effective care measures (4–6). However, care pathways for patients with AKI are not well defined. It is very likely that considerable variability in clinical practices has led to differences in the incidence and outcomes of AKI in different medical centers (7,8). In addition, most institutions do not track adherence with process measures that might impact on the care of patients with AKI. Thus, a critical step in improving the outcome of patients at risk of or with AKI is to identify quality indicators and care pathways that optimize care (Figure 1, Supplemental Appendix 1) (9).

Quality indicators represent the measurement, monitoring, evaluation, and communication of targeted areas of care processes that assess whether and how often the system does what it is intended to do. Quality indicators are framed as determining the structure (i.e., where health care is delivered), process (i.e., how health care is provided), and outcomes (i.e., the effects of health care delivery) of health care systems (Table 1) (10). A challenge in the field of AKI care has been identifying evidence-based quality indicators that guide optimal care as well as recognize opportunities for continuous quality improvement (11). The lack of quality indicators contributes to considerable variation in care and difficulty in studying what interventions may lead to improved outcomes. For instance, patients with AKI often have missed opportunities that otherwise may limit their risk of AKI development or progression. These missed opportunities could be recognized and measured to facilitate development of process improvement strategies. Development of quality indicators must be conducted in a comprehensive manner and started at the community level and continued through and after hospital admission as this represents the spectrum of AKI care continuity (Figure 2). In addition, AKI quality improvement should be evidence-based where possible and responsive to emerging data, despite the fact that current level of knowledge may be limited in its scope for prevention, management, and treatment of AKI.

To achieve a framework for improvement in AKI care, the 22nd Acute Disease Quality Initiative (ADQI) conference was convened. The work was divided into five separate groups that captures the spectrum of AKI care (Figure 2, Table 2). Supplemental Appendix 2 provides details on the ADQI consensus conference, Supplemental Table 1 provides definitions, and Supplemental Table 2 outlines requirements for AKI quality care that were developed as a framework for quality indicators.

22nd ADQI groups and objectives

Community Health Care Standards for AKI

Question 1: At the Community Level, What Are the Roles and Responsibilities of Clinicians and Health Care Systems in AKI Risk Monitoring and Mitigation?

Consensus Statement A.

Healthcare systems and healthcare professionals should identify populations and patients at risk of AKI and implement monitoring and preventive interventions to decrease the incidence of AKI.

Consensus Statement B.

We suggest that a minimum set of baseline risk factors and acute exposures (Figure 3) be considered for AKI risk stratification.

Figure 3.
Figure 3.

KHA and response. KHA includes AKI history, BP, CKD, serum Creatinine level, Drug list, and urine Dipstick (ABCD). Exposures include Nephrotoxic Medications, Imaging, Surgery, Sickness (NISS). KHR (4Ms) that encompasses Medication review to withhold unnecessary medications (e.g., nonsteroidal anti-inflammatory drugs [16,17]), the Minimization of nephrotoxic exposures (e.g., intravenous contrast [18]), Messaging the healthcare team and patient to alert the high risk of AKI, and Monitoring for AKI and its consequences. Reprinted from Acute disease quality initiative (ADQI) (12), with permission.

At least 50% of AKI episodes begin in the community setting (13,14). The initial step toward quality improvement in this setting begins with identifying high-risk populations (defined in Supplemental Table 1) for which monitoring and preventive strategies should be targeted (Figure 3). The definition of high risk may vary according to the local prevalence of different AKI risk factors. These risks can be categorized into five dimensions of inherent and nonmodifiable (for example, age), exposure-based (such as administration of nephrotoxic medications), processes of care (such as failure to identify AKI), socioeconomic-cultural (such as access to care), and environmental (such as exposure to environmental toxins) (Supplemental Figure 1, Supplemental Table 1) (15). Although governmental systems should focus on identifying and managing environmental and socioeconomic-cultural risks, clinicians should focus on individual patient risks that may be detectable and modifiable. Raising awareness regarding AKI risk factors among health care professionals and patients by education and establishment of tools that measure these risk profiles for each individual are considered crucial steps in mitigating AKI incidence.

Question 2: How Should AKI High-Risk Populations Be Monitored?

Consensus Statement A.

We suggest populations/patients at high risk for developing AKI should have a Kidney Health Assessment (KHA) at least every 12 months to define and modify their AKI risk profile.

Consensus Statement B.

We suggest that high-risk patients have another KHA at least 30 days before AND again 2–3 days after a planned exposure that carries AKI risk. The KHA can be tailored to the clinical context and clinician/health care system judgment.

Consensus Statement C.

We suggest that clinicians review a patient’s KHA immediately after an unplanned acute exposure that carries AKI risk.

Literature is limited regarding AKI risk monitoring (19). We suggest that basic risk assessment and care management elements relevant to high-risk patients be considered the minimum standard of care. These elements are synthesized into a KHA. The minimal KHA is outlined in Figure 3. Adherence with and timeliness of the KHA could be used as a quality indicator measurement. For instance, practices should monitor the proportion of patients at high risk for AKI who have documented KHA in their health records.

Question 3: How Can AKI Preventive Strategies Be Implemented within High-Risk Populations?

Consensus Statement A.

KHA should be followed by a Kidney Health Response (KHR) after acute exposure to risk factors of AKI.

Consensus Statement B.

We suggest raising awareness of the definition, signs, symptoms, and acute exposures associated with AKI among clinicians and high-risk patients/populations.

Consensus Statement C.

We suggest enhanced coordination between all stakeholders to monitor the rate, causes, and outcomes of AKI to identify variations in care and outcomes across and between the populations.

The KHA is a “living document” and should be reviewed after acute AKI exposures (20) and updated with new knowledge. This step should then be followed by a KHR (Figure 3). Quality indicators could include adherence with key elements of the KHR as well as the rate of AKI after high-risk exposures. With the emergence of new knowledge, components of KHA (related to patient and population condition) and KHR (indicator of physician task list) need to be updated. The national/local health care system engagement in quality improvement projects is of importance (Figure 3) (21). The effect of environmental factors (e.g., climate, water quality) and the social and behavioral determinants of health (e.g., nutrition, health insurance) on the incidence of AKI are well documented (15,22), and governing bodies have a responsibility to monitor AKI risks and coordinate preventive strategies (23).

Primary Prevention of AKI during a Hospital Encounter

Question 1: How and When Should the Risk for AKI Be Identified among Hospitalized Patients?

Consensus Statement A.

All patients at hospital admission should be screened for risk of AKI. Screening should occur at the earliest possible time throughout the patient’s hospital stay.

Consensus Statement B.

All patients at risk for AKI should at least have an assessment of serum creatinine, urine dipstick analysis, and urine output. Complementary diagnostic tests depending on local availabilities, risk factors, clinical context, and clinician judgment should be considered.

Consensus Statement C.

All hospitalized patients should have periodic risk reassessment using appropriate clinical or electronic models before and after risk exposure or change in clinical status.

Because of multiple exposures, hospitalized patients are at higher risk of AKI in comparison with individuals in the community, regardless of their baseline risk. Therefore, hospitalized patients require more detailed and frequent evaluation when compared with high-risk individuals in the community. Early and frequent screening of hospitalized patients for the risk of AKI should occur. This screening may use validated risk assessment models (24) or automated surveillance tools (25), but at a minimum an assessment should identify susceptibilities and exposures that could lead to AKI (Table 3) (26,27). The intensity, frequency, and duration of monitoring should be individualized according to patient characteristics and local resources.

View this table:
Table 3.

AKI risk assessment among hospitalized patients

Question 2: What Core Preventive Measures Should Be Considered as a Target for Quality Improvement Projects?

Consensus Statement A.

Early correction or mitigation of context-specific modifiable risk factors of AKI should be considered for all high-risk patients.

AKI has been shown to be preventable in recent studies (4,5). Increasing awareness among clinicians regarding the risks and management strategies would most likely result in improved care. The most common conditions leading to AKI include (1) critical illnesses, (2) major surgical procedures, and (3) exposure to nephrotoxic drugs. Optimization of hemodynamic and volume status and avoidance of nephrotoxic insults remain the mainstay of primary prevention. However, to understand the optimal management strategies and targets, further studies are required (26,28).

Question 3: What Are the Quality Indicators for Assessing Risk of AKI?

Consensus Statement A.

The quality indicators for AKI prevention in the hospital should include (1) proportion of patients screened for AKI risk among all admissions, (2) proportion of identified AKI high-risk patients among all screened patients, (3) proportion of AKI high-risk exposures (e.g., medication, contrast, surgery) among all hospitalized population and all high-risk patients, (4) proportion of patients who received an appropriate intervention around a high-risk exposure, and (5) proportion of patients who developed AKI (community- or hospital-acquired; as defined in Supplemental Table 1) among all admissions (in different subpopulations) and all high-risk patients.

Consensus Statement B.

The quality indicators should be reviewed and utilized to identify areas of improvement and action. The frequency of reporting should be defined according to local resources and regulatory requirements.

Identification of valid quality indicators of care is essential to measure, monitor, benchmark, and target the improvement. Quality indicators may include health care infrastructure and access, processes of care, outcomes, and clinician or patient experience (Supplemental Figure 2). It is recognized that these measures vary depending on the health care system, local resources, geography, and socioeconomic, political, and cultural factors (Figure 4). Future investigations should focus on identifying valid and globally applicable AKI risk scoring systems using available and novel tools (e.g., electronic health records, biomarkers).

Figure 4.
Figure 4.

Factors related to quality indicators and reporting can be divided in structure, process, and outcome in community, hospital, and after initiation of KRT. Clearly, different levels exist depending on resource possibilities. For example, resource-sufficient areas may have access electronic medical records, allowing system-driven identification and prevention and more detailed outcome reporting of patients with AKI. Embedded in these is a basic level of quality measures and level of reporting that should be feasible in both resource-limited and research-sufficient areas (white boxes).

Secondary Prevention of AKI

Question 1: What Are the Key Considerations for Developing Quality Programs that Evaluate Contributors to an Episode of AKI?

Consensus Statement A.

We propose that for each patient diagnosed with AKI during hospitalization, the goal is recovery to baseline kidney function in the shortest period of time with minimum number of complications. This is best achieved by timely and accurate diagnosis and management of AKI, and prevention of complications. These goals might be achieved by using a Recognition-Action-Results framework (Table 4).

View this table:
Table 4.

Recognition-Action-Result framework for secondary prevention of AKI, including diagnosis and evaluations, limiting duration and severity of AKI, and prevention of avoidable complications associated with AKI

Consensus Statement B.

Quality improvement surrounding the diagnostic evaluation of AKI should attempt to maximize the proportion of patients who undergo a context-appropriate and timely evaluation while avoiding unnecessary testing.

The timely and accurate identification of reversible causes of AKI, if promptly addressed, potentially reduces the severity and duration of disease and associated complications (secondary prevention of AKI) (29). Quality improvement initiatives surrounding the diagnostic evaluation of AKI should be developed within the contexts of clinical setting (e.g., community- versus hospital-acquired, medical versus postsurgical); the distribution of underlying causes, trajectory, and severity at the time of AKI identification; and the goals and capabilities of the health care systems (30). Although the heterogeneity of AKI and lack of available evidence do not support the notion that all patients with AKI require the same breadth or intensity of evaluation, clinical practice guidelines and expert opinion generally favor a stepwise approach (Table 4) (15,26,29,31–34). We recommend development of quality initiatives surrounding diagnostic evaluation considering the clinical context and the likelihood of identifying actionable causes in a timely and context-specific manner (Supplemental Table 3, Table 4).

Question 2: What Are the Key Considerations for Developing Quality Improvement Programs Focused on Limiting the Duration and Severity of AKI?

Consensus Statement A.

Quality improvement programs should include the implementation and reporting of the proportion of patients that receive timely and diagnosis-appropriate interventions. Adherence with the locally agreed upon preventive interventions should be audited and shared with clinicians periodically.

Reducing the severity and duration of AKI rests on timely and effective management of the underlying causes and reduction in modifiable determinants of ongoing injury. Quality programs may focus on instituting general “nephroprotective” interventions, such as timely hemodynamic resuscitation, nephrotoxin stewardship, or cause-specific interventions (e.g., relief of obstruction, immunosuppression, and others) (4,5,35). Recently, “bundled AKI care pathways” have shown promise in preventing AKI and reducing its severity, but more research is required to better define effective care components (4,36,37). In cases where context-appropriate evaluation identifies a cause warranting targeted therapy, the timeliness and appropriate application of cause-specific management could be measured as quality indicators (Supplemental Table 4, Table 4).

Nephrotoxin exposure accounts for up to 28% of potential adverse drug events leading to AKI and is a potential target for quality improvement (38). Analogous to antimicrobial stewardship programs, the concept of nephrotoxin stewardship encompasses coordinated interventions designed to decrease nephrotoxin exposure among patients at risk for or with AKI (39,40). This provides a framework for the development of institution-specific guidelines for the safe and effective use of Kidney Excreted and Nephrotoxic Drugs. Recently, the Nephrotoxic Injury Negated by Just-in-time Action program demonstrated that the systematic review of nephrotoxins by a multidisciplinary care team resulted in a sustained reduction in nephrotoxin exposure, AKI rate, and severity (41). Similar programs have been tested in adults and resulted in favorable outcomes (4,5,33,42,43). The implementation of these programs must consider the health care system capabilities and the risk–benefit of withholding potentially beneficial nephrotoxins used to treat serious conditions. Within resource-limited areas, dedicating efforts in training appropriate staff (e.g., house staff, nurses, etc.) and reviewing medication lists could potentially provide a similar benefit.

Question 3: What Are the Key Considerations for Developing Quality Improvement Programs Focused on Reducing the Complications of AKI?

Consensus Statement A.

Quality indicators for prevention of avoidable AKI-related complications include monitoring, reporting the context-specific adverse events (to patient advocates, clinicians, administrators, and regulatory bodies), and implementation of risk reduction strategies.

Uremic related complications of AKI and risks associated with initiation of KRT (bloodstream infection, electrolyte abnormalities, hypotension, etc.) or other AKI-related management options (diuresis, withholding nephrotoxins, etc.) should be monitored and reported. We propose that quality programs focus on determining the incidence of complications to appropriately guide effort allocation to the monitoring complications (i.e., recognition of hyperkalemia), the response (e.g., action to treat it), and whether risk reduction strategies are in place (e.g., low potassium diet, no potassium maintenance in fluids) (Supplemental Table 5, Table 4).

Kidney Replacement Therapy Quality Indicators

Consensus Statement A.

Quality indicators should integrate structure, process, and outcome indicators for each therapeutic modality.

There is limited data on acute kidney replacement therapy (KRT) quality indicators, along with numerous challenges with respect to quality and safety in the provision of acute KRT care (44). All institutions that provide acute KRT should adopt and implement a quality framework around these services. This should include integration, monitoring, and reporting of structure, process, and outcome indicators across all forms of acute KRT therapies (Figure 4) (45). Benchmarks for each quality indicator should be determined to provide information about patient-specific and aggregate institutional quality of care. Multicenter, acute KRT registries should be created to further develop and refine quality improvement projects that develop target benchmarks for clinical practice guidelines.

Question 2: What Are the Minimum Structure Quality Indicators that Should Be Implemented for Acute KRT?

Consensus Statement A.

Structural quality indicators should specifically target clinician, nursing, and allied health professionals’ capacity and expertise for providing acute KRT and identify a responsible team to implement and report quality metrics for acute KRT services.

Institutions that provide acute KRT should establish standards for structural quality indicators that incorporate evaluation of resource availability and the infrastructure needed for acute KRT. At a minimum, this should include a dedicated team comprising expert clinicians, nurses, and allied professionals (i.e., biomedical engineer, pharmacist) that are responsible for patient monitoring, reporting data, and design and implementation of quality care processes for each acute KRT modalities.

Question 3: What Are the Minimum Process Quality Indicators that Should Be Implemented for the Provision of Acute KRT?

Consensus Statement A.

Process quality indicators should incorporate methodologies that lead to standardized protocols and procedures, allowing for increased efficiency and consistency in care and safety, and should be specific to each KRT modality.

Institutions providing acute KRT should incorporate standardized clinical protocols and procedures for each KRT modality to deliver consistent and safe care. Key measures of KRT adequacy should be measured routinely (Figure 4). Implementation of quality improvement methodologies should be conducted when there are significant deviations in the provided care (Supplemental Figure 3). Root cause analyses should be used to investigate deviations in practice and to identify care gaps when they occur (Supplemental Figure 4). Future studies should further evaluate, validate, and prioritize specific process quality indicators.

Question 4: What Are the Minimum Outcome Indicators that Should Be Implemented for the Provision of Acute KRT?

Consensus Statement A.

Outcome quality indicators should include patient-centered outcomes, including clinician and patient satisfaction, mortality, and quality of life among survivors; dialysis liberation rates; and health-economic outcomes.

Programs providing acute KRT should integrate, monitor, and report outcome indicators for acute KRT. The monitoring of adverse events is vital to ensure that acute KRT is being delivered in a safe and high-quality manner. Future work should evaluate the association of specific outcome quality and value indicators (i.e., health care costs) for patients, institutions, and health care systems. Evaluating target benchmarks for each quality indicator that can inform patient-specific and aggregate institutional quality of care is crucial for future work.

Tertiary Prevention of AKI Short- and Long-Term Complications

Question 1: How Should the Appropriate Post-AKI/Acute Kidney Disease Care Be Measured?

Consensus Statement A.

Health care systems need to quantitate the proportion of patients who need post-AKI/acute kidney disease (AKD) follow-up, those who receive any post-AKI/AKD follow-up, and evaluate quality of care for those who received post-AKI/AKD follow-up.

Tertiary prevention of AKI should focus on maintenance and/or improvement in quality of life after AKI to mitigate long-term disabilities resulting from AKI. In this regard, current data on post-AKI/AKD follow-up is very limited. The first step to improve quality in this domain is to systematically measure the proportion of patients who receive post-AKI/AKD follow-up care. There is no current standardized definition of “appropriate” AKI-AKD follow-up care, and it varies from no follow-up to a simple serum creatinine check to a nephrology clinic visit. In a report of post-AKI care, only 3% (low-risk patients) to 24% (individuals with both diabetes and CKD) were followed by a nephrologist within 6 months of their AKI episode (46,47). Furthermore, rates of kidney-related laboratory testing after hospital discharge are low. For example, in the United States in 2013, follow-up creatinine measurements occurred only in 54% of patients (46). In addition to determination of those who need follow-up, the setting (i.e., dedicated post-AKI nephrology clinic versus primary care follow-up), timeline (e.g., immediately after hospital discharge or 3 months after AKI episode), and frequency (e.g., weekly or annually) of appropriate post-AKI follow-up also depends on the severity of the initial AKI/AKD and the health care system resources (Figure 5). In follow-up, a multidisciplinary approach (pharmacy, dietician, social work, primary care, nephrology, non-nephrology subspecialists) is recommended. We recommend all patients with dialysis-requiring AKI/AKD or patients with AKI/AKD superimposed on advanced CKD should be followed by a nephrologist at least within 2–3 months after their hospitalization, depending on the severity and acute needs. Future research should focus on the definition of appropriate AKI-AKD follow-up on the basis of severity and cause of AKI, and health care system capabilities. Identifying the patients/populations who benefit the most from follow-up (e.g., AKI cause and severity) and barriers to post-AKI/AKD follow-up care are critical next steps in AKI research and quality improvement.

Figure 5.
Figure 5.

Schematic for AKI/AKD follow-up. The figure displays a potential paradigm for the care of patients who experience AKI/AKD. The degree of nephrology-based follow-up increases as the duration and severity of AKI/AKID increases. The timing and nature of follow up are suggestions as there is limited data to inform this process. Future research effort should work to clarify the timing and health care providers who should be providing AKI/AKD follow-up. The items in each bucket follow the “OR” rule; therefore, each patient should follow the most severe bucket if even meet one criteria of that bucket (e.g., patient with CKD stage 4 regardless of severity of AKI should be followed by nephrologist in 1 week). Reprinted from Acute disease quality initiative (ADQI) (12), with permission.

Question 2: What Are the Key Elements of an Appropriate Post-AKI/AKD Care Bundle?

Consensus Statement A.

Quality indicators should at least include structure (needed personnel and resources), process for follow-up (who and by whom, what, where, when, why, and how), and outcome indicators (CKD progression, continued or new need for dialysis, mortality, etc.).

We recommend the following key components for a post-AKI/AKD bundle that should be a more comprehensive version of KHR: (1) KAMPS (Kidney function, Advocacy, Medications, Pressure, Sick day protocol) for all patients with AKI, and (2) WATCH-ME (Weight assessment, Access, Teaching, Clearance, Hypotension, Medications) for patients with AKI who require dialysis (Table 5). For patients with AKI who require dialysis, care bundles that are appropriate for ESKD may not apply (e.g., early placement of an arteriovenous fistula or graft may be inappropriate for AKI). Quality indicators should be tied to patient and hospital-centered outcomes such as readmission rate and quality of life.

View this table:
Table 5.

Post AKI/AKD kidney health care bundle

Future research should include the use of measures of kidney functional reserve, real-time GFR monitoring, and other novel biomarkers in the post-AKI/AKD setting that correlate with outcomes of interest. In addition, research should focus on optimal management strategies for each component of the KAMPS/WATCH-ME bundles and the development and validation of novel and effective bundle components.

Determination of factors that predict and promote kidney recovery and mitigate CKD development and appropriate implementation of such interventions would also improve quality of care after AKI.

Conclusions

Strategizing improvement in care for AKI requires prioritization and implementation of focused quality improvement projects including all types of health care providers along with change management to leverage the current and future knowledge in the betterment of care. The AKI care process starts with the community, continues in the hospital, and ends in community, and each of these phases requires specific intervention. The group has suggested outlines for the care of individuals in each phase, to focus, enhance, and study quality indicators.
