Abstract

Introduction:

Earthquakes are sudden-onset natural disasters that are associated with substantial material damage, resulting in the collapse of built environment with a high rate of mortality, injury, and disability. Crush syndrome, which can be seen after devastating earthquakes, can lead to acute kidney injury (AKI) and patients may require amputation, fasciotomy, and dialysis. Supportive treatment has an important role in the prognosis of these patients.

Study Objective:

The aim of this study was to investigate the demographic and clinical characteristics of traumatic earthquake survivors admitted to the emergency department (ED) of a hospital, which was close to the earthquake zone but not affected by the earthquake, after the February 6, 2023 Kahramanmaraş (Turkey) earthquakes.

Materials and Methods:

This study was conducted by retrospectively analyzing the data of 1,110 traumatized earthquake survivors admitted to the ED of a tertiary care university hospital from February 6th through February 20th, 2023. Age; gender; time of presentation; presence of comorbid diseases; ED triage category; duration of stay under debris; presence of additional trauma; laboratory tests; presence of AKI; presence of crush injury and injury sites; supportive treatment (fluid replacement and intravenous [IV] sodium bicarbonate); need for amputation, dialysis, and fasciotomy; duration of hospitalization; and outcome of ED were evaluated.

Results:

Of the 1,110 traumatic victims in this study, 55.5% were female patients. The mean age of the patients was 45.94 (SD = 16.7) years; the youngest was 18 years old and the oldest was 95 years old. Crush injury was detected in 18.8% and AKI in 3.0% of the patients. Dialysis, amputation, and fasciotomy were required in 1.6%, 2.8%, and 1.4% of the patients, respectively. In total, 29.2% of patients were hospitalized, including 2.9% admitted to the intensive care unit (ICU) and 26.3% to the relevant ward. In total, 0.3% of the patients included in the study died at ED.

Conclusion:

Post-earthquake patients may present with crush injury, AKI may develop, and fasciotomy, amputation, and dialysis may be needed, so hospitals and EDs should be prepared for natural disasters such as earthquakes.

Introduction

Earthquakes are sudden-onset natural disasters that are associated with substantial material damage, resulting in the collapse of built environment with a high rate of mortality, injury, and disability. On February 6, 2023, two consecutive earthquakes measuring 7.7 and 7.6 on the Richter scale, epicentered in Kahramanmaraş Province, southeastern Turkey, occurred at 04:17am and 13:24pm, resulting in one of the major natural disasters of the last century. The earthquake caused immense destruction of a total of 11 provinces and 62 towns in the proximity of the epicenter. According to the available data at the time of this article, more than 50,000 people were killed and over 107,000 were injured.

Majority of fatality associated with earthquakes occur during the first hours immediately following the earthquake and are mostly due to asphyxiation, compression, and head-neck trauma. Reference Chan, Lin and Chen1,Reference Aoki, Nishimura and Pretto2 Injuries, mainly in the form of fractures, mostly manifest as orthopedic injuries and cause significant morbidity. Those injuries are especially prevalent in the lower extremities. Reference MacKenzie, Banskota, Sirisreetreerux, Shafiq and Hasenboehler3

Crush syndrome is the second most common cause of mortality upon direct impact of trauma during destructive earthquakes. Reference Ukai4 Renal replacement therapy (RRT) is of vital importance in case of abnormal laboratory results indicative of acute kidney injury (AKI), fatal hyperkalemia, and severe acidosis that may develop as complications in those patients. Reference Oda, Tanaka and Yoshioka5,Reference Better and Stein6 Amputation, fasciotomy, and debridement may be required in cases with compartment syndrome. Reference Reis and Michaelson7

The present study aimed to investigate the demographic and clinical characteristics of traumatic earthquake survivors presented to the emergency department (ED) of a hospital, which was close to the earthquake zone but remained intact after the February 6th Kahramanmaraş earthquakes.

Methods

Study Design

Data from patients presented to the ED of a university hospital providing tertiary health care were retrospectively analyzed in the scope of the study.

Inclusion Criteria

Patients presented to the ED from February 6th through February 20th, 2023; diagnosed as an earthquake victim (diagnosis code X34 pursuant to International Classification of Diseases, Tenth Revision, Clinical Modification [ICD 10]); exposed to earthquake-related physical trauma; and aged 18 years or above with complete data were included.

Exclusion Criteria

Non-earthquake-related cases; earthquake-related patients who were not exposed to physical trauma; patients admitted to the ED with other medical problems; and patients with missing data were not included.

Data Analysis

Age, sex, date of presentation, comorbid diseases, ED triage category, duration of stay under debris, injury sites, specific laboratory tests (serum hemoglobin, leukocytes, platelets, urea, creatinine, sodium, potassium, calcium, phosphorus, troponin I, myoglobin, creatine kinase, and blood gas [pH, bicarbonate, base deficit] values), AKI and crush injury, treatments, ED and hospital outcomes, and length of hospital stay were recorded on the data form prepared in advance for the purposes of the study. The data were obtained by retrospectively examining the patients who applied to the ED from February 6th through February 20th, 2023, were diagnosed as earthquake victims (X34 diagnosis code according to ICD-10 diagnosis coding), and were registered in the hospital information management system NUCLEUS v9.38.50 (MONAD Software and Consultancy; Turkey) Medical Information System.

Presentation dates were captured under three categories as the “First Three Days,” “Days 4–7,” and “Days 8–14.” Triage categories at presentation were defined as Red code (immediate, life-threatening injuries), Yellow code (delayed, non-life-threatening injuries), and Green code (minimal, minor injuries). The patients’ triage categories were determined by a senior Emergency Medicine specialist. Patients who had crush injury and developed oligo-anuria (<400 mL/day) or required dialysis treatment for at least one day were diagnosed with crush syndrome. Reference Slater and Mullins8 In addition, AKI was defined as crush syndrome combined with associated nephrological conditions which might require dialysis. Patients with nephrological conditions were defined as patients who required dialysis or were characterized by one of the following parameters: oliguria (urine output ≤400mL/day), blood urea nitrogen (BUN; >40mg/dL), urea (>85.6mg/dL), serum creatinine (>2.0mg/dL), uric acid (>8.0mg/dL), potassium (>6.0mEq/L), phosphorus (>8.0mg/dL), and calcium (<8.0mg/dL). Both RRT and its indications were determined pursuant to the recommendations of the Turkish Society of Nephrology (İstanbul, Turkey) following the 1999 Marmara earthquake in northwestern Turkey. Reference Sever9

The present study was performed upon the approval of the Clinical Research Ethics Committee, Mersin University Rectorate (Mersin, Turkey; dated March 15, 2023; No. 2023/168).

Statistical Analysis

Shapiro–Wilk test was used to test the hypothesis of normal distribution of the study data. Mean and standard deviation (SD) and median and quartiles were used as descriptive statistics for parameters that met and did not meet the normal distribution hypothesis, respectively. Categorical variables were expressed in numbers and percentages.

Student’s t-test was used to investigate presence of significant intergroup differences by mean in groups that met normal distribution hypothesis, and Mann–Whitney U test was used in the groups without normal distribution. Chi-squared test was used to investigate whether there was a correlation between categorical variables.

A P value of <.05 was considered statistically significant.

Results

A total of 5,622 patients were evaluated within the specified date range. Of those, 3,579 patients who were not related to the earthquake and 933 patients who were related to the earthquake but were not exposed to physical trauma and admitted to the ED because of medical problems were excluded from the study. There were no cases with missing data. Accordingly, the study comprised of 1,110 patients, including 55.5% female patients. The mean age of the patients was 45.94 (SD = 16.7) years. The mean age of women and men was 46.74 (SD = 17.1) and 44.93 (SD = 16.3) years, respectively (P = .075). In total, 16.1% (n = 179) of the patients included in the study aged 65 years and above. Overall, 18.8% and 3.0% of the patients were diagnosed with crush injury and AKI, respectively. Dialysis, amputation, and fasciotomy were required in 1.6%, 2.8%, and 1.4% of the patients, respectively. In total, 29.2% of patients were hospitalized, including 2.9% admitted to the intensive care unit (ICU) and 26.3% to the relevant ward. Overall, 0.3% of the patients included in the study died at ED.

The mean duration of stay under debris was 4.21 (SD = 12.6) hours and the maximum duration was 120 hours. A total of 6.5% of the patients presented with multiple traumas.

Patients mostly presented within the first three days after the earthquake. Patients with triage categories of Red and Yellow mostly presented during the first three days, whereas patients encoded Green presented on the other days (P <.0001). The rates of crush injury, AKI, and requirement for dialysis by age groups and the rates of AKI and requirement for dialysis by crush injury sites are given in Table 1.

The amputation rate for lower extremities was higher compared to the upper extremities in patients who required amputation (58% and 42%, respectively; P = .421). Similarly, the rate of fasciotomy in lower extremities was higher compared to that in the upper extremities (56.2% and 43.7%, respectively; P = .934). The rate of amputation was 2.9% in patients aged below 65 years of age, whereas the same rate was 2.2% in patients over 65 years of age (P = .611). The rate of fasciotomy was 1.6% in patients aged below 65 years and 0.6% in patients over 65 years of age (P = .227).

The duration under debris (P <.0001); serum hemoglobin, leukocyte (P = .001), calcium, troponin, myoglobin, creatine kinase (P <.0001), and base deficit (P = .025) values; and duration of hospital stay (P <.0001) were associated with amputation. Similarly, the duration under debris (P <.0001); serum calcium (P = .003), troponin (P = .001), myoglobin (P = .006), and creatine kinase (P <.0001) values; and duration of hospital stay (P <.0001) were associated with fasciotomy. Differently, serum platelet (P = .031), urea (P = .009), creatinine, potassium (P = .049), and sodium (P = .007) values were also associated with fasciotomy (Table 4).

The patients were most frequently hospitalized during the first three days (40.3%), whereas the highest discharge rate was between days eight and fourteen (83.3%), when a higher rate of Green encoded patients received medical care (P <.0001). One patient died during the first three days and two patients died between days four and seven at ED. In all three patients, the cause of mortality was cardiac arrest due to crush syndrome and metabolic acidosis.

There was a statistically significant, positive, and moderate linear relationship between the duration under debris and hospital stay (correlation coefficient 0.535; P <.0001).

Discussion

The present study provides important results as regards to AKI occurrence and amputation, fasciotomy, and dialysis in traumatic patients presented to the hospital ED upon the Kahramanmaraş earthquake.

The rate of female patients presented to the hospital was similar to the 2020 Turkey Aegean Sea–Izmir earthquake study Reference Uz, Cetin, Songur Kodik, Guvenc, Karbek Akarca and Ersel10 and higher than the male patients. The mean age of the patients in 2020 study was 38.0 (SD = 21.0) years compared to 45.94 (SD = 16.7) years in the present study. The fact that only patients aged 18 years and above who presented to the ED were included in the present study, whereas pediatric patients were included in the 2020 study, may account for this difference.

Most post-earthquake hospital presentations occur during the first 72 hours following the disaster. Reference Tanaka, Oda and Iwai11,Reference Peek-Asa, Kraus and Bourque12 The majority of presentations to this hospital occurred within the first three days, affirming the above hypothesis, similar to the study conducted after the 1999 Marmara earthquake in Turkey. Reference Sever, Erek and Vanholder13 A study on the Aegean Sea–Izmir earthquake, which measured at a lower Richter scale with a shorter duration compared to the Kahramanmaraş earthquake, reported that approximately 41.5% of the patients presented during the first three hours of the earthquake. Reference Uz, Cetin, Songur Kodik, Guvenc, Karbek Akarca and Ersel10 For the Izmir earthquake, patients affected by the earthquake sought medical care in hospitals in the same city, and therefore, the time of presentation was earlier. The current hospital is approximately three hours by land route from Hatay Province, one of the most earthquake-affected provinces and one of the provinces where patient transfers were the most common. Nevertheless, due to the damage to highways and airline runways and the failed telephone and internet connections, it took six-to-seven hours for patients to be transferred after they were rescued from under the debris. There was no direct patient transportation during the first 36 hours, except for some patients who were able to present by their own means or using a limited number of ambulances. The day after the earthquake (as of 1:00pm on February 7), a ship providing medical services started to transport patients to the province via Iskenderun Port every 24 hours, and after the relative improvement of transportation conditions, there was marked increase in simultaneous and multiple presentations of patients. The earlier the patient is presented, the fewer complications due to earthquake-related injuries are likely expected to occur. This proves that search and rescue teams should organize their pre-disaster plans for possible mishaps in order to make patient referrals and transfers on time and reduce the duration under debris so that the national health services can be streamlined.

Triage practices at ED are vital in mass disasters. The majority of patients presented to the hospital within the first three days fell under the triage category Yellow. A study by Uz, et al, which investigated the presentations after the Izmir earthquake, reported that patients encoded Yellow presented the most on the first day, with higher frequency of presentation during the first hour, and the patients encoded Yellow had the higher rate of presentation during the study. Reference Uz, Cetin, Songur Kodik, Guvenc, Karbek Akarca and Ersel10 The fact that Green encoded patients watched for their relatives under the debris, whereas Red encoded patients had difficulty in arriving by their own means and might have been transferred only by ambulance at a later stage, may account for this result.

Head, chest, and abdominal injuries during earthquakes are generally more fatal compared to extremity injuries. Therefore, these patients who accessed health care services might be lower. Reference MacKenzie, Banskota, Sirisreetreerux, Shafiq and Hasenboehler3 A study on the 2015 Nepal earthquake reported the rate of lower extremity injuries as 89%. Reference Almeida, Loenhout and Thapa14 In the present study, the patients mostly had upper and lower extremity injuries.

Crush injuries are prevalent consequences of natural disasters, including earthquakes, and are estimated to affect 3%-20% of victims. Reference Wolfson15 Previous studies in the relevant literature suggested that children and elderly people were less likely to suffer from the pathophysiologic consequences of crush syndrome, and thus rhabdomyolysis. This was explained by the fact that younger and middle-aged people had higher rates of solid mass, and that most of the child and elderly victims who might be more prone to trauma were likely to have lost their lives during the earthquake. A Marmara earthquake study Reference Sever, Erek and Vanholder13 suggested the above hypothesis and reported that patients with crush injuries aged between 20 and 59 years. In the present study, the mean age of patients with crush injury was 46.0 (SD = 17.9) years.

Although it was suggested that the traumatic pressure on muscles should last at least four hours and should be continuous for crush syndrome may occur, it was reported that there were patients who were rescued within the first hour after the Kobe earthquake who developed crush syndrome. Reference Sever, Erek and Vanholder13 In the present study, the mean duration of stay under debris in patients with crush syndrome was six hours.

It is not only rhabdomyolysis that triggers AKI, but also the pace of rescue efforts, basic survival supplies available to patients, and meteorological conditions. Reference Van der Tol, Hussain and Sever16 It was reported that AKI occurred in 1.5% of all patients presented to reference hospitals during the Marmara earthquake, where the same rate was 1.9% during the Aegean-Izmir earthquake. Reference Uz, Cetin, Songur Kodik, Guvenc, Karbek Akarca and Ersel10,Reference Sever, Erek and Vanholder13 In the present study, AKI rate (3.0%) was higher compared to the above two studies. The first-line treatment recommendations of the Renal Disaster Relief Force aimed to prevent AKI after the Marmara earthquake included fluid administration started on-site and as early as possible, isotonic saline, 5.0% glucose, and bicarbonate liquid support, along with monitoring of urine output. Reference Vanholder, Sever, De Smet, Erek and Lameire17 Duration under debris is an important indicator as regards to occurrence of AKI due to crush injuries and is considered a factor which affects prognosis in patients. Reference Sever, Erek and Vanholder18 Most studies suggested the patients who developed AKI had longer delays in receiving supportive treatment compared to patients without AKI. Reference Uz, Cetin, Songur Kodik, Guvenc, Karbek Akarca and Ersel10 During the Izmir earthquake, the longest duration under the rubble was 91 hours, Reference Uz, Cetin, Songur Kodik, Guvenc, Karbek Akarca and Ersel10 whereas in the present study, it was 120 hours. It was reported that the rate of development of AKI was higher in patients with longer duration of stay under the debris in the Iran Bam earthquake, similar to the results of the present study. Reference Bonomini, Stuard and Dal Canton19 The high rate of AKI occurrence in the present study is suggestive of the fact that patients presented to the hospital had a longer duration under debris and that the patients could have received delayed medical care.

In Marmara, AKI occurred in approximately 50% of patients with crush syndrome, and approximately 50% of those patients required dialysis. Reference Vanholder, Sever, De Smet, Erek and Lameire17 While it was reported that 74.6% of patients with AKI in the Marmara earthquake required hemodialysis, Reference Sever, Erek and Vanholder13 only four (23.5%) out of 17 patients with crush injuries during the 2003 Bingöl earthquake in Turkey required dialysis. Reference Bonomini, Stuard and Dal Canton19 In the present study on the Kahramanmaraş earthquake, the same rate was 7.2%. The foregoing low rate may be explained by the fact that almost all of the patients with AKI were administered with intravenous (IV) fluid and sodium bicarbonate support pursuant to the previous recommendations. This is suggestive of the fact that the lessons taken from Turkey’s long history of severe and recurrent earthquakes are beginning to clearly show their results. A mortality rate of 17% was reported in a study of post-earthquake dialysis patients, Reference Vanholder, Sever, De Smet, Erek and Lameire17 which is similar to the present study (16.7%).

Ischemic changes can be reversed during the first six hours by reducing compartment pressure in patients with acute compartment syndrome using fasciotomy. Amputation should be considered in patients with crush injury; in cases of all severe soft tissue damage with or without fracture; in patients with cardiac, respiratory, and renal dysfunction; and with sepsis. Reference Wolfson15 The total amputation and fasciotomy rates (3.8%) at the Aegean earthquake Reference Uz, Cetin, Songur Kodik, Guvenc, Karbek Akarca and Ersel10 and the amputation rate (3.15%) upon the Marmara earthquake Reference Gul and Andsoy20 were close to each other and similar to the results of the present study. The lower extremity amputation rate was higher compared to that of upper extremity in the present study. This may be explained by the higher rate of lower extremity injuries in these patients compared to the upper extremities and the higher incidence of nutritional disorders associated with vascular factors in the lower extremities compared to the upper extremities.

Following the Wenchuan earthquake, Reference Zhang, Fu and Wang21 the rate of fasciotomy and amputation was lower in elderly patients compared to the younger patients. Similar results were found in the present study. This may be associated with the fact that compartment syndrome is less likely in elderly patients.

A study on RRT after the Marmara earthquake Reference Sever, Erek and Vanholder22 reported that patients who required dialysis treatment had higher serum leukocyte, urea, creatinine, potassium, phosphorus, and creatinine kinase values. Those results were consistent with the present study. Furthermore, patients who required dialysis had lower serum sodium and calcium levels. The low blood calcium and high leukocyte rates of those patients who required RRT were similar to those of the patients after the L’Aquila earthquake. Reference Bonomini, Stuard and Dal Canton19 Van der Tol, et al investigated the metabolic profile in patients with crush injuries and AKI after the Kashmir and Marmara earthquakes, and accordingly, suggested that the mean serum creatinine, phosphorus, and calcium values of the patients during the Marmara earthquake were lower compared to the patients injured during the Kashmir earthquake. Reference Van der Tol, Hussain and Sever16 The results of the patients in the present study were similar to that of the patients injured during the Marmara earthquake. Serum potassium values of the victims of Kashmir and Marmara earthquakes were similar and are very close to the results of the present study.

There was a higher rate of ward hospitalization and a lower rate of ICU admission compared to the Aegean earthquake. Reference Uz, Cetin, Songur Kodik, Guvenc, Karbek Akarca and Ersel10 The mortality rate during the first 72 hours was lower compared to the Marmara earthquake. Reference Sever, Erek and Vanholder13 Those differences with regard to the ED outcome suggest that seriously injured patients might not have been transported on time due to severed logistics and many of them most likely did not survive long enough to present to this hospital. This is further supported by the fact that the highest mortality rate in the Marmara earthquake was seen in patients who arrived by boat from Yalova within the first hour, and that the number of patients who died at the ED during the Aegean earthquake was six, whereas the same number was three in the present study.

The obtained results were consistent with previous studies in the relevant literature, which is suggestive of the fact that patients with crush injury and AKI, who also underwent dialysis, amputation, and fasciotomy, had prolonged hospital stay compared to others. Reference Almeida, Loenhout and Thapa14

Limitations

The fact that the current hospital was one of the two hospitals providing tertiary care services in its region and that the adequate referral process could not be maintained due to transportation and telecommunication problems during the first 72 hours following the disaster might have led to a difference in the patient profiles referred and less patient admission compared to other hospitals. In addition, the fact that the study was conducted in a single institution constitutes another limitation.

Conclusion

In this study, it was determined that the number of patients admitted to the ED in the first three days of the earthquake and patients with Red triage category were higher. It was determined that patients with crush injuries, amputation, and fasciotomy had longer duration of stay under the debris; patients with crush injuries needed more amputation, fasciotomy, dialysis, and prolonged hospitalization. In the light of all these data, appropriate preparations should be made for disasters such as earthquakes; correct triage should be ensured in emergency services; and adequate equipment, treatment areas, dialysis units, and operating room environments should be established in the hospital. It should be kept in mind that post-earthquake patients may present with crush syndrome and its complications, and in these patients, fluid and bicarbonate liquid support should be given as early as possible in order to reduce the development of AKI and the need for dialysis.
