Conditions: Hip Fractures
Keywords: Blood Transfusion Hip Fracture Surgery Replacement Trauma
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 283
Healthy volunteers: no

Brief summary:
The overall design of the study is a prospective, double-blinded, randomized study in the geriatric hip fracture population comparing those who receive intravenous tranexamic acid prior to incision to those who receive a placebo.

Detailed description:
A significant portion of the geriatric hip fracture population have comorbidities including chronic kidney disease, congestive heart failure, ischemic heart disease, stroke, etc. These patients may be anemic prior to the surgery, and are at increased risk for further blood loss as a result of the fracture and surgical operation. However, intra-operative or post-operative blood transfusions also increase the risk of renal and cardiac complications in this population.

Tranexamic acid (TXA) is an anti-fibrinolytic medication that has transformed total joint replacement management regarding blood loss prevention. Geriatric patients requiring emergent hip fracture repair may significantly benefit from routine administration of TXA prior to the procedure to decrease the risk of blood loss. Thus, treatment may further reduce the percentage of patients who experience blood transfusions and complications associated with transfusions.

The investigators will examine if administration of TXA prior to incision in the geriatric hip fracture patient population decreases the risk of intra-operative or post-operative blood transfusions compared to placebo.

INTRODUCTION: 
 
Doctors may ask patients to take part in a research study. Before a patient agrees, the 
doctor or research staff must give the patient information about the risks and benefits of the 
study. The form you are about to read gives such detailed information. Once you 
understand the study, you can decide if you want to take part in it. 
 
We are asking you to join a research study for people who have a hip fracture and need 
surgery to fix it. We want to learn if the drug tranexamic acid (TXA), given just before 
surgery, can reduce the need for blood transfusions. The drug helps promote blood clotting. 
It is approved by the US Food and Drug Administration (FDA) for other uses but not for hip 
fracture surgery. The risk is that TXA also could increase blood clotting that could lead to a 
heart attack or stroke. We want to learn if the benefits outweigh the risks for hip fracture 
patients. We will do this by assigning the patients in the study at random (like flipping a 
coin) to either get TXA before surgery or to get a placebo. Patients and surgeons will not 
know who got TXA. Then, we will collect data from the patients’ medical records on how 
they are doing for 3 months after surgery. We will compare the data from the two groups. 
 
If you join the study, you do not need to do anything extra. You just need to follow up with 
your surgeon for usual care. 
 
It is your choice whether to join the study. You may refuse; it will not affect the care you 
receive at Lancaster General Hospital. You could still receive TXA outside of the study, 
depending on the choice of your surgeon. If you join the study, you will need to sign this 
consent form. You will receive a copy of it for your records.

LGH IRB Approved February 7, 2024, through February 6, 2025 
 
III. 
PURPOSE: 
 
 
The purpose of this study is to learn if patients who get TXA before hip fracture surgery are 
less likely to get blood transfusions than patients given placebo. We also want to compare 
how long they stay in the hospital and how many come back to the hospital within 30 days. 
Finally, we will compare the groups for complications from either the drug or from blood loss 
or blood transfusions. This will allow us to assess if the benefits of TXA outweigh the risks. 
 
Other studies have shown that TXA reduces the need for blood transfusions in patients who 
have knee or hip replacements (when they don’t have a fracture). We don’t know if the 
same will be true for hip fracture patients. Hip fracture patients may have a higher risk of 
problems from either the drug or the surgery. 
 
IV. 
NUMBER OF SUBJECTS: 
 
The study plans to enroll 425 people here at Lancaster General Hospital. 
 
V. 
PROCEDURES, LENGTH OF STUDY INVOLVEMENT, AND REQUIRED FOLLOWUP: 
 
Your surgeon has already decided what type of surgery you need to have and has 
determined that you are eligible for the study. If you agree to join the study, we will use a 
random process (much like flipping a coin) to decide whether you receive TXA or placebo. 
The random process is important. It allows us to compare TXA and placebo in a fair manner 
(without bias). You and your surgeon will not know if you got TXA or not. Your surgery and 
your care after surgery otherwise will be the same as it would be if you did not join the 
study. You will not have any extra tests for the study. You will see your surgeon 2 weeks, 6 
weeks, and 3 months after surgery for check-ups.  
 
Your surgeon will assess how you are doing at each visit. We also will check your medical 
records to see if you have had any other appointments for problems that could be related to 
your hip surgery. If you saw any doctors outside Lancaster General or were in another 
hospital, it is important that you let us know. With your permission, we will get information 
from the other doctors and hospitals about any problems that could be related to your hip 
surgery. 
 
VI. 
BENEFITS: 
 
Other studies have shown that TXA reduces the need for blood transfusions with planned 
surgery to replace knee or hip joints. It is possible that the same may be true for hip fracture 
surgery. We don’t know for sure, which is why we are doing the study. 
 
VII. 
RISKS AND DISCOMFORTS: 
 
Because TXA prevents blood clot breakdown, the concern is that it could cause unwanted 
blood clots. Such clots could lead to a heart attack, stroke, or a clot in the leg, lung, or 
elsewhere. Other possible serious side effects are seizure or severe allergic reaction. 
 
Possible, less serious side effects include: 
• 
Headache of migraine 
• 
Myalgia (body aches and pains) and fatigue 
• 
Anemia

LGH IRB Approved February 7, 2024, through February 6, 2025 
 
• 
Shortness of breath or dizziness 
• 
Hypotension 
• 
Nausea, diarrhea, or vomiting 
• 
Flushing or rash 
 
It is possible there are some risks from TXA that are not yet known. 
 
IX. 
ALTERNATIVES: 
 
 You do not have to take part in this study. You will still receive standard care if you are not 
in this study. You might even still get TXA. Whether you get TXA will be based on your 
surgeon’s medical judgment rather than on the random process the study uses. 
 
X. 
PAYMENTS AND COSTS: 
 
Study costs will be funded by a grant from the von Hess Foundation.  
 
There will be no cost to you for taking part in this study. You will not receive any payment 
for being in the study. 
 
XI. 
COMPENSATION FOR INJURY OR COMPLICATION: 
 
If you are injured because of the study, you could need medical treatment for your injuries. 
You or your insurance company would be responsible for the costs of that treatment.   
 
Lancaster General Hospital does not have a program to pay for medical expenses, lost 
wages, lost time or discomfort for such injuries.  
 
You do not waive any legal rights to seek compensation by signing this consent form.  
 
XII. 
VOLUNTARY PARTICIPATION / RIGHT TO WITHDRAW: 
 
Your participation in this study is voluntary. This means it is your choice whether or not to 
take part. You may refuse to take part in this study before you have your surgery. You will 
not lose benefits you would otherwise receive or suffer any penalty if you do so. You also 
will not jeopardize the medical care you receive from your doctor. 
 
If you want to withdraw from the study after your surgery, you may do so. This means that 
we would not collect information from your medical records about how you are doing. 
However, because staying in the study at this time does not involve anything extra for you, 
we will ask you to consider allowing us to collect your data as planned. 
 
XIII. 
QUESTIONS ABOUT THE RESEARCH:

Population for the Reduction of Post-Operative Blood Transfusion 
Short Title 
TAHFT 
IRB Number 
Please note that this number will be assigned by the IRB and thus will not be in 
existence at the time of protocol development and initial review.  
Methodology 
The overall design of the study is a prospective, double-blinded, randomized 
study in the geriatric hip fracture population comparing those who receive 
intravenous tranexamic acid prior to incision to those who receive a placebo.  
Study Duration 
The patient enrollment phase will take approximately 24 months. Study 
duration for each subject is 3 months. Total study duration is expected to be 36 
months, allowing for study start-up before enrollment and data analysis and 
manuscript writing after completion of study follow-up.  
Study Center(s) 
Lancaster General Hospital 
Specific aims 
Primary: 
• 
To compare the percentage of subjects that receive acute post-operative 
transfusions in the group administered intravenous tranexamic acid 
compared to the group administered placebo 
Secondary: 
• 
To compare length of inpatient hospital stay and the percentage of 
subjects with readmissions with associated diagnoses within 30 days 
between the treatment groups 
• 
To compare rates of complications and mortality within 90 days post hip 
surgery between the treatment groups 
Number of Subjects 
The study will enroll approximately four hundred (400) qualified subjects.   
Main Inclusion and 
Exclusion Criteria 
INCLUSION - Eligible subjects will meet ALL the following criteria: 
1. Written informed consent 
2. Age ≥ 65 years 
3. Hip fracture location within the femoral neck, intertrochanteric, and 
subtrochanteric regions 
4. Indication for surgical intervention with one of the following: 
hemiarthoplasty, total hip replacement, sliding plate and screw 
fixation, or intramedullary fixation.  
 
EXCLUSION – Eligible subjects will NOT meet any of the following criteria: 
1. Indication for closed reduction and percutaneous screw fixation 
2. Allergy to tranexamic acid 
3. Cerebrovascular accident/stroke, active coronary disease/myocardial 
infarction, or deep vein thrombosis/pulmonary emboli within one (1) 
month prior to the fracture 
4. Presence of hypercoagulable disorder 
Intervention  
The intervention in the two arms consists of administration of 1) 100 cc normal 
saline with 1g of tranexamic acid in solution or 2) 100 cc normal saline alone.

Statistical 
Methodology 
For assessing the primary endpoint, we will calculate an odds ratio (with a 
95% confidence interval) for transfusion with p-values calculated using a 
likelihood ratio. 
Data and Safety 
Monitoring 
Monitoring of adverse events will occur every 6 months over the course of the 
study or more frequently if needed. One interim analysis is planned to assess 
the primary endpoint for significant efficacy sufficient to stop the trial early. 
The interim analysis is planned for the ¾ point of the trial or a minimum of 
300 subjects enrolled. 
 
Background and Study Rationale 
1 
Introduction 
Geriatric hip fracture patients may significantly benefit from routine administration of tranexamic 
acid (TXA) prior to the procedure to decrease the risk of blood loss. Thus, this may further reduce 
the rate of blood transfusions and complications associated with this treatment. With the high 
volume of geriatric hip fractures treated at Lancaster General Hospital, we would obtain a large 
patient population to perform an ideal study.  
1.1 
Background and Relevant Literature  
The geriatric hip fracture population is growing throughout the United States secondary to the aging 
baby boomer population. These fractures require surgical intervention for stabilization and proper 
rehabilitation. During the 2017 fiscal year, 420 hip fracture operations were performed at Lancaster 
General Hospital on the geriatric population, and this number has been increasing over the past 
decade. This population has a significant increase in morbidity and mortality (approximately 50%) 
within 1 year if the patient does not have an operation within 36 hours of the trauma.1,2 Therefore, 
patients are quickly optimized to a degree where they are safe to tolerate the anesthesia and surgical 
procedure. 
  
A significant portion of the geriatric hip fracture population have comorbidities including chronic 
kidney disease, congestive heart failure, ischemic heart disease, stroke, etc.3 These patients may be 
anemic prior to the surgery, and are at increased risk for further blood loss as a result of the fracture 
and surgical operation.4,5 However, intra-operative or post-operative blood transfusions also increase 
the risk of infectious and non-infectious complications (i.e. anaphylaxis, acute hemolytic reaction, 
circulatory overload, metabolic derangements, etc.), cost of admission, and length of stay in this 
population.6-8 Evidence has demonstrated that postoperative cardiovascular complications are 
associated with anemia and blood transfusions.9-11 Therefore, providers must be cautious and aware 
of risks when deciding if transfusions are indicated for this population. 
  
Tranexamic acid (TXA) is an anti-fibrinolytic medication that has transformed total joint replacement 
management regarding blood loss prevention. Multiple studies have proven its effectiveness of 
significantly reducing blood loss during total hip and knee replacement procedures compared to 
placebo.12-28 Thus, this medication has drastically reduced the need for post-operative transfusions in 
this patient population. However, this patient population may be optimized prior to surgery if they 
have significant anemia because joint replacement surgeries are generally elective and not urgent or 
emergent. 
  
Geriatric patients requiring emergent hip fracture repair may significantly benefit from routine 
administration of TXA prior to the procedure to decrease the risk of blood loss. Thus, treatment may 


TAHFT

Version: 1.0 
 
 
 
further reduce the percentage of patients who experience blood transfusions and complications 
associated with transfusions. However, there are only a couple of studies analyzing the use of TXA in 
the hip fracture population, and these were underpowered.29-31 Additionally, the American Academy 
of Orthopedic Surgery and American Association of Hip and Knee Surgeons released guidelines 
regarding the use of tranexamic acid based on existing literature and clinical evidence.32 They stated 
the greatest shortcoming in the literature is the lack of high level evidence to support the use of TXA 
in patients with a history of VTE, myocardial infarction, cerebrovascular event, transient ischemic 
attack, and/or vascular stent placement.  Therefore, they encourage future research to determine the 
safety of TXA in the high-risk patient. 
 
With the high volume of geriatric hip fractures treated at Lancaster General Hospital (LGH), we aim 
to obtain a large patient population to perform an ideal study. We would examine if administration of 
TXA prior to incision in the geriatric hip fracture patient population decreases the risk of intra-
operative or post-operative blood transfusions compared to placebo and determine the safety profile 
of such administration in high-risk patients.

Study Objectives 
2.1 
Primary Objective 
The primary objective of the study is to determine if administration of pre-operative intravenous 
tranexamic acid for surgical geriatric hip fracture subjects reduces the need for post-operative blood 
transfusions compared to the geriatric hip fracture subjects who are administered placebo.  
2.2 
Secondary Objectives 
A secondary objective is to determine if TXA increases the risk of complications in the geriatric hip 
fracture population compared to placebo. Complications may include deep vein thrombosis, 
pulmonary emboli, myocardial infarction, and cerebral vascular events.  We also monitor for 
complications in subjects who do not receive the TXA.  We also will look for differences between the 
groups in 30 day readmission rates. 
3 
Investigational Plan  
3.1 
General Design 
The overall design of the study is a prospective, double-blinded, randomized study comparing the 
post-operative rate of blood transfusions in surgical geriatric hip fracture subjects who are 
administered intravenous TXA prior to incision compared to those who receive a placebo.  
 
Data will be collected at Enrollment, Baseline, Hospital Discharge, and at Follow Up Visits at 2 (two) 
weeks, six (6) weeks and three (3) months in conjunction with their standard of care post-operative 
visits.  In addition, all unscheduled visits, hospital readmissions, and deaths will also be collected at 
6 weeks and 3 months post-surgery. 
3.2 
Allocation to Interventional Group 
Consented subjects are randomized to participate in the study if they meet eligibility criteria. 
Subjects are randomized in a 1:1 ratio to receive either TXA (intervention), or placebo (control). The 
randomization will be stratified by the type of procedure: 
1. Hemiarthroplasty/total hip replacement 
2. Internal fixation with sliding hip screw/cephalomedullary nail 
Each stratum will have its own list of random treatment assignments to promote balance in the 
treatment groups with respect to the stratification factors. The treatment assignments will be 
computer-generated in blocks of varying sizes using REDCap.

Study Population and Duration of Participation  
Subjects will be recruited from geriatric hip fracture patients acutely admitted through the Lancaster 
General Hospital Emergency Department and treated by OAL physicians. Consenting subjects will be 
followed for 90 days post-surgery. Participation ends upon the completion of the 3-month post-
operative visit with the OAL provider. 
 
The enrollment phase is projected to take approximately 24 months.  
4.1 
Total Number of Subjects and Sites  
The study enrollment is planned to be 400 subjects who meet eligibility criteria and consent to the 
study.  The study will be conducted at only one (1) site, Lancaster General Hospital.   
4.2 
Inclusion Criteria 
A patient who meets all of the inclusion criteria and none of the exclusion criteria is eligible to 
participate in this study.  Patients are enrolled in this investigation only when they or their legally 
authorized representative have signed and dated a written Patient Informed Consent.   
 
Inclusion criteria that must be met are the following: 
1. Provision of written informed consent 
2. Age ≥ 65 years 
3. Hip fracture location within the femoral neck, intertrochanteric, and subtrochanteric regions 
4. Indication for one of the following surgical interventions: hemiarthroplasty, total hip replacement, 
sliding plate and screw fixation, or intramedullary fixation  


TAHFT 
 
Page 8 
Version: 1.0 
 
 
 
4.3 
Exclusion Criteria 
Patients will be excluded for the following: 
1. Indication for closed reduction or percutaneous screw  
2. Allergy to TXA 
3. Cerebrovascular accident/stroke, active coronary disease/myocardial infarction, or deep vein 
thrombosis/pulmonary emboli within one (1) month of the fracture 
4. Presence of hypercoagulable disorder,  including cancer (active disease), elevated blood 
homocysteine levels, antiphospholipid antibody syndrome and inherited protein deficiencies 
(antithrombin III, factor V Leiden, protein S & C deficiencies, prothrombin gene mutation) 
4.4 
Subject Recruitment  
Given approximately 75% of the hip fractures in Lancaster County present at Lancaster General 
Hospital and are operated on by OAL physicians, there is not a need for marketing or advertising to 
recruit study subjects.  OAL’s volume of hip surgeries performed in calendar year 2018 was over 300. 
 
Eligible patients based on the above inclusion criteria and not eliminated by the exclusion criteria will 
be considered potential candidates for the study.  Potential subjects will be approached to participate 
in the TAHFT study in the emergency room department or operating room holding area of LGH prior 
to hip surgery. 
 
Once enrolled, a subject is expected to comply with the standard follow-up visit schedule.   
4.5 
Vulnerable Populations  
Children, pregnant women, fetuses, neonates, and prisoners are not included in this research study.  
 
The study may include subjects who are not medically or cognitively able to provide consent and 
authorization for themselves, and people for whom Spanish, Vietnamese, Nepali, or Arabic is their 
native language. The consent and authorization process for these subjects in addressed in Section 
11.2. 
5 
Study Intervention 
The study drug, TXA, is an anti-fibrinolytic. By reducing the conversion of plasminogen to plasmin, it 
preserves the structure of fibrin and prevents its degradation. 
5.1 
Intervention Regimen  
In joint replacement surgery, TXA is used at a dosage of 1 g in a 100 cc bag of normal saline, 
administered intravenously within 30 minutes before incision. 
5.2 
Regulatory Status of the intervention 
Intravenous TXA is approved for marketing by the U.S. Food and Drug Administration and is 
indicated in patients with hemophilia undergoing tooth extraction to reduce blood loss and prevent 
hemorrhage. Pre-operative administration in joint replacement is an off-label clinical use. The use in 
the TAHFT study will be an off-label research use for which we are requesting the IRB to make a 
determination on IND exemption. The research is not intended to be reported to the FDA in support 
of a new indication or a significant change in labeling or advertising of the drug, and it does not 
involve a route of administration, dosage level, or population that significantly increases the risks 
associated with TXA. 
5.3 
Risks 
The literature does not demonstrate significant complications with TXA administered intravenously in 
the surgical orthopedic total joint population. However, these studies have not analyzed this drug 


TAHFT 
 
Page 9 
Version: 1.0 
 
 
 
administered to the high risk population, which includes those with recent ischemic cardiac events 
(myocardial infarctions) or thromboembolic events (cerebrovascular accident and deep vein 
thrombosis/pulmonary emboli), and patients with hypercoagulable disorders. Because of the 
uncertainty whether this drug increases the risk of embolic events, we aim to eliminate patients with 
ischemic cardiac and thromboembolic events within 30 days prior to surgery, and those with 
hypercoagulable disorders, which are the highest risk patients. However, we plan to include patients 
with events that occurred more than 30 days prior to surgery with the aim to learn more about these 
at-risk patients, in accordance with the recommendations of the American Academy of Orthopedic 
Surgery and the American Association of Hip and Knee Surgeons as previously cited. 
 
As a precaution, a post-operative dose of TXA will not be given to any subject enrolled in this study. 
5.4 
Potential Benefits  
Administration of TXA may decrease the need for post-operative blood transfusions and the 
complications associated with transfusions and anemia. TXA may also decrease the rate of 
readmissions especially related to anemia. There are several studies in the literature that support that 
TXA administration may be beneficial in decreasing post-operative blood loss in major orthopedic 
surgery.14-28 In addition, there are smaller studies examining the hip fracture population showing 
potential benefit.5, 29-31  
5.5 
Randomization  
Based on the kind of fracture, the treating surgeon will decide on the type of surgical procedure to be 
performed. The surgeon will designate the type of procedure in the order placed in Epic for TAHFT 
study drug.   
 
Upon receipt of the Epic order, a study trained OR pharmacist will log into the REDCap TAFHT 
database.  The pharmacist enters the consented subject’s name, MRN, and the designated surgical 
procedure (stratum).  REDCap generates the subject’s Study ID and then the stratified randomization 
assignment to TXA or placebo.  
 
For subjects randomized to the intervention arm, a pharmacy technician prepares a plain 100 cc 
normal saline bag with 10 cc of 100mg/cc TXA-saline (110 cc total). For subjects randomized to 
placebo, a plain 100 cc normal saline bag containing an additional 10 cc of saline (110 cc total) will 
be used. A TAHFT study label with subject MRN will be affixed to the plain 100 cc normal saline bag.  
A trained study pharmacist confirms the work of the pharmacy technician and confirms the REDCap 
randomization assignment and appropriate study drug/placebo saline bag preparation.  The saline 
solution and tranexamic acid will be used from the pharmacy available stock.   
 
Upon approval, the pharmacist technician prepares the study treatment to be picked up by 
anesthesia in the OR pharmacy location. Anesthesia confirms study subject identity, and blinded 
study drug is administered prior to surgical incision.  
 
5.6 
Blinding  
Only the trained study pharmacists will not be blinded to treatment assignment. The operating room 
staff, surgeon, anesthesiology, research coordinator, and research assistant will be blinded for the 
duration of the study, as will the subjects themselves.

6.1 
Enrollment 
Hip fracture patients will be evaluated for appropriateness of surgery and follow the standardized 
pre-operative testing protocol, which will include lab tests to evaluate patient safety including 
complete blood counts, comprehensive metabolic panels, and prothrombin time. More advanced lab 
testing and medical imaging, i.e. EKGs, troponins, CT scans, MRIs, ECHOs, etc., will be done at the 
discretion of the treating surgical and medical teams as indicated.  
 
OAL physicians will evaluate X-rays to classify the fracture and determine the surgical procedure.  
 
Study enrollment procedures involve checking inclusion and exclusion criteria and consenting eligible 
subjects or their legally authorized representatives. For eligible patients, OAL physicians will follow 
the Informed Consent process described in Section 11.2 to discuss the study purpose, risks, benefits, 
and alternatives to participation and to address the questions and concerns of patients or legally 
authorized representatives. After the consent process is complete, the OAL physician will document 
the consent process within the Epic subject medical record. 
 
The study physicians will track all hip fracture patients who they screened but did not meet eligibility 
criteria or who refused study participation. Additionally, the Clinical Research Coordinator (CRC) will 
obtain hospital data on all hip fracture patients from the fracture liaison service. This information, 


TAHFT 
 
Page 11 
Version: 1.0 
 
 
 
which will be recorded in a de-identified manner, will allow assessment of the generalizability of study 
results. 
6.2 
Surgical Period 
The surgical period includes subject randomization and administration of study drug just prior to 
surgery. The research subject receives appropriate hip fracture surgical intervention based on their 
fracture pattern and determination by the treating surgeon.   
 
The CRC will review Epic for peri-operative study data including: 
• 
Lab work: CBC (Complete Blood Count), CMP (Comprehensive Metabolic Panel), PT/INR 
(prothrombin time and International Normalized Ratio) 
• 
Blood transfusions administered peri-operatively 
• 
Hemoglobin/hematocrit (H/H) levels before and after blood transfusions 
• 
Adverse events 
6.3 
Follow Up 
6.3.1 Hospital Discharge 
The CRC reviews Epic for post-operative study data including: 
• 
Lab work: CBC (Complete Blood Count), CMP (Comprehensive Metabolic Panel), PT/INR 
(prothrombin time and International normalized ratio) 
• 
Blood transfusions administered post-operatively 
• 
Hemoglobin/hematocrit (H/H) levels before and after post-operative blood transfusions 
• 
Adverse events 
6.3.2 Follow Up Visits 
The subject receives routine hip fracture post-operative care per the LGH geriatric fracture program.  
The post-hospital observational phase will include a minimum of two post-operative follow-up 
evaluations at two (2) weeks, six (6) weeks, and three (3) months.  
 
The two (2) week, six (6) week, and three (3) month standard of care post hip surgery patient 
assessment will include evaluation of the following: 
• 
X-rays to evaluate hip fracture and hardware placement 
• 
Dressing check (2 week only) 
• 
Physical therapy progress 
• 
Weight bearing status 
• 
Pain medication management 
• 
Post-operative anti-coagulation management 
• 
Bone density osteoporosis prevention conversation 
 
The CRC conducts a medical chart review at the 6 week and 3 month time points for scheduled and 
unscheduled office visits a subject has with any provider for the following items: 
• 
Subject assessment by the OAL provider 
• 
Medication changes and updates 
• 
Laboratory tests (if done) 
• 
Hospital readmission and associated diagnosis in the interim since discharge after hip surgery 
• 
Adverse events 
 
If a subject reports visits or hospitalizations outside the LG system, study personnel will request 
permission to obtain data from the providers or health systems. If a subject is reported to be 
deceased during the follow-up period, the CRC will record this event in the study database. 


TAHFT

Version: 1.0 
 
 
 
6.4 
Unscheduled Visits 
It is anticipated that <5% of subjects require an additional unscheduled visit.  Typically additional 
visits are to evaluate wound healing. Any relevant information from these visits will be captured by 
the medical chart reviews at 6 weeks and 3 month. 
7 
Statistical Plan 
Statistical support will be provided by the Lancaster General Research Institute. 
7.1 
Sample Size and Power Determination 
Power calculations are based on the assumptions that 20% of the control group will require 
transfusion as a result of the hip fracture and surgery, and that use of TXA will reduce that 
percentage by half to 10%. For 80% power with a two-sided alpha of 0.05, and using a likelihood 
ratio test, the sample size is calculated to be 200 per group with a 1:1 assignment ratio, or 400 total 
subjects. 
7.2 
Statistical Methods 
For assessing the primary endpoint, we will calculate an odds ratio (with a 95% confidence interval) 
for transfusion with p-values calculated using a likelihood ratio.  
 
As a secondary outcome, daily hemoglobin and hematocrit levels will be assessed using a mixed-
effects linear model with adjustment for appropriate covariates. Safety/complication outcomes such 
as 30-day readmissions, embolic events or other complications will be assessed using appropriate 
binary or Poisson models. Descriptive statistics using appropriate comparative models will be used to 
assess homogeneity of demographics and any differences in outcomes between the control and 
intervention groups. 
 
One interim analysis is planned to assess the primary endpoint for significant efficacy sufficient to 
stop the trial early. The interim analysis is planned for the ¾ point of the trial or a minimum of 300 
subjects enrolled. To compensate for one interim and one final analysis, we will employ the O’Brien-
Fleming adjustments to significance level criteria with p < 0.0054 for the interim analysis and p < 
0.0492 for the final analysis. Based upon a simulation of our primary outcome, futility will be reached 
at the interim analysis point if the control group has a 30 (30/150 = 20%) or fewer subjects that 
have experienced a transfusion and the intervention group has 26 (26/150 = 17.3%) or more 
subjects that have experienced a transfusion. Even if the remaining 50 intervention subjects to be 
enrolled experience no transfusions and the transfusion rate remains at 20% in the control group, H0 
will not be rejected.

Safety and Event Reporting 
The study will comply with requirements of the Lancaster General Human Research Protection 
Program (HRPP) policies regarding reporting of unanticipated problems and adverse events.  
8.1 
Recording of Adverse Events 
Numerous complications or sequelae of hip fracture surgery are outcomes for the study. Only adverse 
events that are related to the study treatment itself will be considered study adverse events. 
 
At each contact with the subject, clinical personnel will seek information on adverse events by 
specific questioning and, as appropriate, by examination. This information will be recorded in the 
electronic medical record. The research coordinator will review and abstract this information into the 
study database, which will provide systematic recording and classification of a specific list of potential 
adverse events. 
 
The clinical course of each event will be followed until resolution, stabilization, or until it has been 
determined that the study intervention or participation is not the cause.  Serious adverse events that 
are still ongoing at the end of the study period will be followed up to determine the final outcome. 
8.2 
Relationship of AE to Study  
The PI will determine, in his judgment, the relationship of each adverse event to the study 
procedures should be characterized. The relationship will be classified as probably related, possibly 
related, or unlikely to be related. 
8.3 
Reporting of Adverse Events and Unanticipated Problems 
Unanticipated problems, as defined by HRPP policy, will be reported to the IRB in accordance with 
the same policy. All other adverse events, withdrawals, and study deviations will be reported in 
summary form during the continuing IRB review of the study or in the final report.

Data Management and Record Keeping 
9.1 
Database and Data Management  
The study database will be designed and maintained in REDCap, a HIPAA compliant database (Harris 
et al). Study staff will be granted access to database sections based upon role. Only the pharmacists 
responsible for randomization will have access to the un-blinded study group assignment assigned by 
and recorded within REDCap. Research staff will have access to enter data but not extract summary 
data. Clinical personnel will not have any access to the study database to maintain equipoise and 
independence. Subject identifiers will be maintained in the database to facilitate the conduct of the 
study and insure accurate data collection. Upon completion of the study, the database will be locked 
and subject identifiers will be secured and not connected with the study data. Study data will be 
maintained in REDCap after completion of the study in archive mode. 
 
The study screening log of patients who are not enrolled in the study will also be maintained in 
REDCap. The log will not contain any personal identifiers for these patients. 
9.2 
Records Retention 
Study records will be retained for a minimum of 6 years, in accordance with HRPP policy.  
10 Study Monitoring 
10.1 
Quality Assurance Monitoring 
The study PI is responsible for ensuring the ongoing quality and integrity of the research study. 
However, as an investigator-initiated study without an external monitor that conducts monitoring, the 
TAHFT study will be prioritized for monitoring by the Research Quality Assurance Office of the LG 
HRPP. Compliance with HRPP policies will be assessed, consent forms will be reviewed, and IRB 
correspondence and any other regulatory documentation will be checked. Study data may be 
sampled to be checked for accuracy. 
 
Should any concerns about non-compliance emerge, HRPP policy for review and investigation will be 
followed.  
10.2 
Data and Safety Monitoring 
The Data and Safety Monitoring Committee (DSMC) for TAHFT comprises four individuals who work 
at LGH. Because the drug is an approved drug and there is significant experience with its use, it is 
believed that an internal committee can adequately monitor the trial. The committee will include a 
trauma surgeon, anesthesiologist, orthopedic surgeon, and orthopedic nurse, as well as a 
biostatistician. In addition, the principal investigator, Gregory Tocks, DO, will attend committee 
meetings to address protocol. As the principal investigator, he is the person most familiar with the 
drug protocol and in the best position to address questions about it. However, he will not participate 
in any votes about study continuation or termination. 
 
The first meeting of the committee will take place once the 50 subjects have been enrolled or after 6 
months, whichever occurs first. Thereafter, the committee will meet biannually to review 
accumulated safety data and as hoc as needed to review or address any adverse events. The 
principal investigator will be aware of all adverse events that may occur in the study and will be 
responsible to call ad hoc meetings of the DSMC if necessary. Specific safety outcomes to be 
monitored include: 
• 
Rate of 30 day readmissions and reason 
• 
Complications within 90 days from surgery 
• 
Other unanticipated events 
 


TAHFT 
 
Page 15 
Version: 1.0 
 
 
 
One interim analysis will be conducted when 75% of enrollment is achieved to determine if the study 
should stop early for efficacy or futility. It also will allow assessment of the benefits concordantly with 
the risks. 
11 Ethical Considerations 
The study will not begin until it has received approval from the LGH Institutional Review Board (IRB). 
Any changes to the protocol or consent form that represent potential changes to the risk-benefit ratio 
or an increase in what is required of subjects will be submitted to the IRB as an amendment for 
review before it is implemented (unless a delay in implementation would compromise subject safety). 
11.1 
Risk-Benefit Assessment 
The study aims to provide data on the risks and benefits of TXA administration in the geriatric hip 
fracture population. While other studies have demonstrated benefit without significant complications 
when given in the orthopedic total joint population, there is not data from large studies conducted in 
the geriatric hip fracture population. The risks may be greater in this generally higher risk population, 
but the potential benefit also may be greater if the frequency of blood transfusion is greater. We 
therefore think the potential risk-benefit ratio is acceptable. The accuracy of this assumption will be 
assessed as the study is ongoing through safety monitoring and the interim analysis. 
11.2 
Process for Obtaining Informed Consent and HIPAA Authorization 
All subjects will be provided a combined, written consent and HIPAA authorization form that 
describes the study in sufficient detail for subjects to make an informed decision about their 
participation in this study. This consent and authorization form will be submitted with the protocol for 
review and approval by the IRB. The formal consent and authorization of a subject, using the IRB-
approved form, will be obtained before that subject undergoes any study procedure.  
 
When obtaining consent and authorization, OAL physicians will discuss the study purpose, risks, 
benefits, and alternatives to participation and address questions and concerns with patients and their 
legally authorized representatives, when applicable. Research staff will be involved in the process of 
obtaining consent and authorization, by discussing with potential subjects the details of the study 
follow-up, how information about them will be used and disclosed, and who to contact in the case of 
injury or with questions or concerns. Given that the study is being conducted in the emergency hip 
fracture population, subjects or their representatives will not have extended time to review the 
written consent and authorization. Therefore, the physicians and research staff will take special care 
to ensure that subjects demonstrate understanding of the study in conversation. Subjects or their 
legally authorized representatives will be asked to sign the written consent and authorization form 
and will be given a copy of the form. After the consent and authorization process is complete, the 
OAL physician will document the process within the Epic subject medical record. 
 
The OAL physician will make the determination as to whether a subject is medically or cognitively 
unable to give consent and authorization and who is appropriate to serve as the subject’s legally 
authorized representative, following LG policies. The subject will be informed about the trial to the 
extent compatible with the subject’s capacity for understanding. If the legally authorized 
representative is not available in person, the consenting physician may transmit the consent form to 
the representative electronically and discuss the study with the representative by phone. The legally 
authorized representative may return a signed copy by fax or email or in person prior to 
randomization. Alternatively, electronic signature may be obtained via the study database in REDCap.  
 
For uses of a short form, an alteration of the HIPAA authorization requirement is requested. That is, 
in these circumstances, authorization to use and disclose health information will be obtained orally, 
but no signature will be obtained in the HIPAA authorization section of the consent form. 


TAHFT

11.3 
Withdrawal of Consent or Revocation of Authorization 
Participation in TAHFT study is voluntary.  Research subjects may withdraw, or their legally 
authorized representatives may withdraw them, from the study at any time during the course of the 
study. Refusing to participate or withdrawing from the research study will not impact a patient’s 
medical care.   
 
Unless a subject withdraws soon after consent and before surgery, it is likely that the study 
intervention will be completed. That is, when a subject withdraws from the study after surgery, s/he 
is withdrawing only from follow-up data collection from the medical record. 
 
Some subjects or legally authorized representatives may wish to withdraw medical care. An OAL 
physician will review with them the standardized routine hip fracture follow up care for 90 days after 
surgery. If the subject or legally authorized representative desires to completely withdraw medical 
care, the OAL provider will document and monitor outcomes via phone calls or chart reviews. Also, if 
a subject relocates out of the Lancaster, PA, geographical area during the acute post-operative 
period, OAL will monitor subject outcomes via phone calls. Subjects will be asked if this information 
may be used in the research study. 
 
Study data collection stops upon subject withdrawal from TAHFT study.  For example, if subjects 
withdraw from the TAHFT study prior to surgery, operative and post-operative data will not be 
collected. Data that have already been collected up until study withdrawal will remain part of the 
TAHFT study database. 
11.4 
Privacy and Confidentiality 
Patients will be approached about participating in the study in the emergency room, patient hospital 
room, or the pre-operative room. They will be extended as much privacy as possible, with 
conversations about the study occurring in the context of therapeutic decision-making. All follow-up 
interactions with participants also will occur in the context of medical care. 
 
The use of subjects’ medical data for research purposes will be explained in the consent and 
authorization process. The study database will contain the participants’ names and medical record 
numbers to facilitate the conduct of the study. The study database will be accessible only to study 
personnel, as described in Section 9.1. 
 
Identifiable data will not be disclosed outside of LG Health. However, subjects will be informed that 
their study data could be de-identified and shared with other researchers. 
 
Data on hip fracture patients who do not participate in the TAHFT study will be recorded in a de-
identified manner, to allow assessment of the generalizability of the patient population and study 
results. 
12 Study Finances 
12.1 
Funding Source 
Funding for this study will be financed through a grant from the von Hess Foundation. 
12.2 
Conflict of Interest 
Research investigators and personnel are required to disclose any financial interests related to their 
job responsibilities on an annual basis. Financial interests are reviewed by the Research Compliance 
Committee as protocols are submitted and as they come up for continuing review. Any potential 
conflicts of interest must be managed to the satisfaction of the IRB to minimize influence on subject 
safety and study integrity.

12.3 
Subject Stipends or Payments 
The study participant will not incur additional costs from participating in this study.  There are no 
programs to pay for medical care necessitated by adverse events associated with participation in this 
study. Payment for care for adverse events associated with TXA drug administration will be the
