Intravenous Fluids in Adults With Diabetic Ketoacidosis in the Emergency Department (BRISK-ED)

Balanced Crystalloids (RInger's Lactate) Versus Normal Saline in Adults With Diabetic Ketoacidosis in the Emergency Department: a Pilot Randomized Controlled Trial (BRISK-ED)

Diabetes mellitus is a common chronic disease. It is estimated that up to 40% of adults may develop diabetes in their lifetime. Patients with poorly controlled blood sugars often visit the emergency department for treatment of potentially dangerous and life-threatening complications of diabetes, including "diabetic ketoacidosis" (DKA), a condition where the body does not have enough insulin or cannot effectively use the insulin that is produced. As a result, the body produces a chemical called "ketones" as another source of energy, which increase the acid levels of blood and impairs organ function throughout the body.

In the emergency department, patients with DKA are usually treated with insulin and large amounts of intravenous fluid. Recent research suggests the fluid type used may be important in treating DKA. Normal saline (0.9% sodium chloride) is the most commonly used intravenous fluid in treating DKA, but it has a very high concentration of chloride and can lead to additional acid production when given in large volumes. Ringer's lactate is another type of intravenous fluid that more closely matches the chemistry of fluid in our bodies and in theory, does not increase the acidity of blood. While there may be benefits to giving Ringer's lactate instead of normal saline, past studies have included very few patients and thus, definite recommendations on preferred fluid type still cannot be made.

This study's research question is: In adults with DKA, does giving Ringer's Lactate result in faster resolution of DKA compared to normal saline? The investigators hypothesize that patients who are given Ringer's Lactate will have faster resolution of DKA. If the hypothesis is correct, results will provide scientific proof that current diabetic ketoacidosis guidelines should change with respect to fluid choice.

In this study, patients with DKA presenting to the emergency department will be randomly assigned to receive either normal saline or Ringer's Lactate. As this is an exploratory (pilot) study, the main goal is to ensure that a larger study will be practical and feasible on a scale involving multiple emergency departments across Canada. Completion of a larger study across multiple sites with more patients will improve our understanding of how fluid choice influences patient-important outcomes such as faster resolution of DKA (meaning patients can leave hospital sooner), fewer admissions to the intensive care unit, fewer deaths and fewer cases of permanent kidney damage. A total of 52 participants (26 per group) will be recruited for this pilot trial.

This pilot study will assess the practicality of enrolling patients in London and help identify barriers and problems with running a larger trial. The overall goal is to determine if Ringer's Lactate will resolve DKA faster than normal saline. If this is true, patients may spend less time in the hospital, which benefits both individual patients and the healthcare system overall. If this hypothesis is correct, findings could provide high-level proof to change current practice guidelines and affect DKA management globally.

Detailed Description

BACKGROUND AND SIGNIFICANCE Diabetic ketoacidosis (DKA) is an acute, life-threatening complication of diabetes which requires treatment with intravenous (IV) fluid and insulin to correct hyperglycemia and reverse acidosis. Current DKA management guidelines recommend normal saline (0.9% sodium chloride) for resuscitation and treatment.1-3 However, saline's chloride content is higher than that of human plasma and can cause a hyperchloremic metabolic acidosis, particularly when administered in large volumes (often needed in patients with DKA). Use of saline may thus worsen the clinical condition of patients who are already in an acidotic state.4-7 Alternatives to saline are balanced crystalloids (e.g. Ringer's lactate-RL) which have chloride concentrations similar to human plasma; therefore, treatment with balanced crystalloids may lead to faster DKA resolution. One recent study (Self et al.) of emergency department (ED) patients presenting with DKA demonstrated that treatment with balanced crystalloids resulted in more rapid DKA resolution compared to saline (13.0 vs 16.9 hours, p=0.004).8 While the difference in resolution time between groups was small, the authors suggested that "consistent implementation of interventions that deliver small improvements in outcomes…can translate into substantial improvements in population health and health system function." However, this study was single-centred, non-blinded, and was a post-hoc subgroup analysis of completed trials (i.e. SMART9 and SALT-ED10) and power was not prospectively calculated. Other studies on this topic have been limited due to small sample sizes (45-77 patients) leading to low power with limited conclusions.11-14

STUDY OBJECTIVE(S); INCLUDING SPECIFIC AIMS AND/OR HYPOTHESES The investigators hypothesize that patients who are administered IV RL will have faster DKA resolution without a concomitant increase in adverse outcomes when compared with normal saline. However, a pilot randomized controlled trial (RCT) is necessary to assess the feasibility of a future multi-centre trial. The specific objectives for this pilot study are to determine the feasibility of conducting a full-scale multi-centred RCT and to use this pilot data to inform the future trial.

METHODS Design and Setting This will be a single-centre, triple-blind pilot RCT evaluating the superiority of IV RL (intervention) compared to saline (comparator) in treating adult ED patients presenting with DKA over a one-year period. The study setting is London Health Sciences Centre (LHSC)'s Victoria Campus, an academic tertiary care centre with ~90,000 ED visits/year in London, Ontario. Study conduct will be in accordance with the CONSORT statement for pilot feasibility trials.15

Study Procedures Screening, Consent, and Enrolment During weekday business hours (M-F 0700-1700), research assistants (RAs) will screen and identify eligible patients using the ED tracking board. They will approach the treating physician to confirm eligibility before discussing the study with the patient and seeking informed consent. Because the diagnosis of DKA requires laboratory confirmation, all patients with a point-of-care blood glucose confirming hyperglycemia (≥14mmol/L) will be approached for enrolment as a "possible DKA patient". If the treating physician agrees that DKA is possible and IV fluid is indicated, study fluid will be administered per the randomization protocol after consent is obtained. If patients are initially enrolled but the physician ultimately confirms they do not meet DKA criteria, they will be excluded from the analysis. During evening and weekend hours, RAs will be available on-call, however nighttime coverage (after 2300h) will not be feasible for this pilot. After hours (and in the event study processes are affected by a prolonged COVID-19 pandemic), treating physicians can directly enroll patients as there will be study posters to outline enrolment processes and physicians will receive email and in-person reminders on study recruitment. Study personnel will review daily ED visit logs to identify missed patients to screen for bias.

Intervention and Comparator The intervention is administration of IV Ringer's lactate and the comparator is administration of IV normal saline. Rate of study fluid will be at the treating physician's (both ED and inpatient, if consulted for admission) discretion. Apart from fluid administered, there will be no other changes to the patient's clinical care, and patients will receive standard DKA treatment which may include insulin, electrolyte replacement, and/or supportive management. Pharmacy-prepared kits of 8 x 1L bags of study fluid (in Self et al., a maximum of 7090mL was given8) will be kept in a secure space within the ED. Once packaged, IV bags are useable for 30 days before expiration. If a kit is opened but not used completely, individual 1L bags may be returned to the pharmacy to save on costs.

Randomization, Blinding, Allocation Concealment Enrolled patients will be block randomized to treatment or comparator in a 1:1 allocation ratio. The block size will be unknown to investigators and those involved in patient care and will be small enough to ensure balance between each arm throughout the trial. The randomization list will be prepared by the pharmacy. The patients, treating physicians, and outcome assessors will be blinded to assigned treatment. The pharmacy will prepare an opaque covering over each fluid bag within study kits, which will not be removed during the infusion to maintain blinding. Each bag will be labelled with a kit number and scannable bar code to ensure the patient receives study fluid as ordered which will be entered on their Medication Administration Record (Figure 1).

DATA COLLECTION Study data for each enrolled patient will be abstracted from the hospital's electronic medical records into the Lawson REDCap data storage platform. Study data will include minimal demographic information (e.g. sex, date of birth), the patient's medical history (e.g. comorbidities, medications), arrival ED information (e.g. CTAS, arrival vitals), hospital interventions (e.g. IV fluids administered), comprehensive bloodwork results, and discharge and outcome information (e.g. length of stay, intubation, diagnosis).

DATA ANALYSIS The investigators will follow an intention-to-treat analysis. Descriptive statistics will be used to summarize patient characteristics. Chi-square tests with 95% confidence intervals will be used to examine differences in categorical variables between groups, and two-tailed unpaired t-tests will be used to compare continuous variables. For this pilot study, no interim analysis, Data Safety Monitoring Board, or adjudication committee is planned, but these will be developed for the full-scale trial. This trial will be registered with ClinicalTrials.gov.

Sample Size The full-scale multi-centred will include 516 participants (258 per arm), assuming α=0.05, power=80%, 1:1 allocation, a 40% (6.76 hours) minimal clinically important reduction in DKA resolution time, and 10% attrition rate. This trial will be conducted at 6 ED sites over 2 years. Based on this, the sample size for this local pilot RCT is 52 participants (26 per arm).

Sample size for Full-Scale Trial The sample size calculation for this trial was based on a study of Clinical Effects of Balanced Crystalloids vs Saline in Adults with Diabetic Ketoacidosis8 which compared the clinical effects of balanced crystalloids with the clinical effects of saline for the acute treatment in DKA in two clinical trials (Isotonic Solutions and Major Adverse Renal Events Trial [SMART]9 and the Saline Against Lactated Ringer's or Plasma-Lyte in the Emergency Department [SALT-ED]10). The primary outcome for this comparison was the time between ED presentation and DKA resolution, measured in hours. Self et al. (2020) found an absolute reduction in time to DKA resolution of 3.9 hours. In the balanced crystalloids group (n=94), the median time to resolution of DKA was 13.0 hrs [IQR: 9.5-18.8], while in the saline group (n=78) the median time to resolution was 16.9 hrs [IQR: 11.9-34.5]. The IQR was used to calculate the standard deviation for each group based on the following assumption for normally distributed data: SD=IQR/1.35. The pooled standard deviation was then calculated based on the sample size and standard deviation of each group from the Self et al. (2020) study [√((n1-1)*SD12 + (n2- 1)*SD22)/(n1+n2-2))] and was determined to be 12.37. To establish superiority of balanced crystalloids versus saline in the time to resolution of DKA, a superiority margin for a clinically significant difference was chosen to be a 40% (=6.76 hours) reduction in time to resolution of DKA based on expert consensus and patient partner feedback. A conservative attrition rate of 10% was selected for the sample size calculation, as loss to follow-up rates should be low given the nature of the intervention (IV fluids) and follow-up period (<24 hours). The actual attrition rate determined by this pilot study will inform the sample size calculation for the full-scale multicentre study. Therefore, to achieve 80% power at the 5% level of significance with equal allocation, the sample size for the balanced crystalloids (Ringer's lactate) group and the saline group, while accounting for a 10% loss to follow up and a 25% reduction in time to DKA resolution, is 516 participants (258 per group). The sample size was calculated using Wang and Ji's (2020) method16 for common clinical study designs available at http://riskcalc.org:3838/samplesize/.

The investigators plan to conduct the full-scale trial at 6 ED sites over 2 years, which would require an average minimum recruitment of 86 participants per site (43 per site per year). This research group has established relationships with these other Canadian EDs and have previously conducted successful studies. If further sites are needed for recruitment, the investigators will leverage the Network of Canadian Emergency Researchers (NCER).

Sample size for Pilot Trial For the full-scale trial, a minimum of 43 participants must be recruited annually per site on average. The LHSC Victoria Campus ED treats approximately 130 patients with DKA annually, based on the hospital's Decision Support data from the most recent fiscal year (Mar 1 2019 - Feb 29 2020).

DKA by Site Patients Victoria Hospital 130 (E1010) Type 1 DM with ketoacidosis 70 (E1110) Type 2 DM with ketoacidosis 51 (E1112) Type 2 DM with keto & lactic acidosis 1 (E1410) Unspecified DM with ketoacidosis 8

Based on research team hours of coverage (0700-2300) and past data from ED presentation time of potentially eligible patients, the investigators expect to approach at least 104 (80%) of eligible patients in the one-year pilot study period, and a minimum of 43 approached participants (41.3%) must be recruited to meet the feasibility target. According to data from similar past trials, the investigators anticipate being able to recruit at least 50% of approached patients (target sample size of 52 patients, 26 in each arm). With 104 patients approached per year, a 90% two-sided confidence interval around the anticipated recruitment rate will have a total width of 0.17, i.e. a lower limit of 0.415 and an upper limit of 0.585. Because the lower limit excludes the minimum feasibility target of 41.3%, the investigators can be 90% confident that the future trial is feasible.

RISKS Participation in this study is entirely voluntary. Patients may refuse to participate, refuse to answer any questions, or withdraw from the study at any time with no effect on their future care. Participants do not waive any legal rights by signing the consent form. They will receive a copy of the letter of information should they be willing to consent.

There are no anticipated risks to participating in this study, other than a low possibility of a privacy breach occurring with the data collected during this study. However, the study team will take all necessary precautions to prevent this from happening and will remove any personal identifiers from all data collection forms.

BENEFITS For participants who are randomized to the Ringer's Lactate Group, there is a possibility that they may benefit from this intervention. The hypothesized benefit from the administration of the IV Ringer's Lactate may include improved faster resolution of DKA than if IV normal saline was administered. However, there is no guarantee that participants will benefit personally from participating in this pilot study.

This study will contribute important knowledge regarding DKA treatment. This pilot study will directly inform if a full-scale clinical trial evaluating the use of a Ringer's Lactate compared to normal saline as part of DKA care in the ED is possible.
