Abstract
INTRODUCTION: A number of studies published by the World Trade Center Health Registry (Registry) document the prevalence of injuries sustained by victims of the World Trade Center Disaster (WTCD) on 9/11. Injury occurrence during or in the immediate aftermath of this event has been shown to be a risk factor for long-term adverse physical and mental health status. More recent reports of ongoing physical health and mental health problems and overall poor quality of life among survivors led us to undertake this qualitative study to explore the long-term impact of having both disaster-related injuries and peri-event traumatic exposure on quality of life in disaster survivors. Methods: Semi-structured, in-depth individual telephone interviews were conducted with 33 Registry enrollees who reported being injured on 9/11/01. Topics included: extent and circumstance of the injury(ies), description of medical treatment for injury, current health and functional status, and lifestyle changes resulting from the WTCD. The interviews were recorded, transcribed, and inductively open-coded for thematic analysis. RESULTS: Six themes emerged with respect to long term recovery and quality of life: concurrent experience of injury with exposure to peri-event traumatic exposure (e.g., witnessing death or destruction, perceived life threat, etc.); sub-optimal quality and timeliness of short- and long-term medical care for the injury reported and mental health care; poor ongoing health status, functional limitations, and disabilities; adverse impact on lifestyle; lack of social support; and adverse economic impact. Many study participants, especially those reporting more serious injuries, also reported self-imposed social isolation, an inability to participate in or take enjoyment from previously enjoyable leisure and social activities and greatly diminished overall quality of life. DISCUSSION: This study provided unique insight into the long-term impact of disasters on survivors. Long after physical injuries have healed, some injured disaster survivors report having serious health and mental health problems, economic problems due to loss of livelihood, limited sources of social support, and profound social isolation. Strategies for addressing the long-term health problems of disaster survivors are needed in order to support recovery.

A large number of studies have shown that victims of natural and human-made disasters experience both adverse physical and mental health effects, with survivors especially at risk of post-traumatic stress disorder (PTSD) and depression.1

5 The World Trade Center Health Registry (Registry) was developed to understand the short, medium, and long-term public health impacts of the attacks on people exposed to the World Trade Center (WTC) disaster on September 11, 2001 (9/11). The Registry enrolled more than 70,000 people who were members of populations at risk, including: those in the vicinity of the attacks in lower Manhattan on 9/11/01 either in buildings (including the WTC Towers) or passing through the area; residents who lived in the immediate area surrounding the WTC site; rescue, recovery and ancillary workers working at the site on 9/11 or on later clean-up and recovery operations; and children who were enrolled in schools in the vicinity of the WTC.1
,
6A study published by the Registry found that over 9,000 (13%) enrollees reported being injured on 9/11.6 The most common injury reported was a sprain or strain.6 Some groups were more likely to be more seriously injured; for instance, while 3,672 (44%) of Registry enrollee survivors were injured, 474 (13%) reported an injury involving a fracture or dislocation, burn, or head injury.7 These and other Registry studies have also found injury to be a significant risk factor for mental health disorders, including a two-fold higher likelihood of PTSD, after controlling for other risk factors.7
,
8 The occurrence of any injury was also found to be independently associated with new onset heart disease post-9/11.8 In addition to well-documented on-going health and mental health problems noted by Registry enrollees who were injured, there have also been numerous anecdotal reports of poor quality of life reported by survivors. Whether this is related to injuries sustained on 9/11 or to peri-traumatic exposure to the disaster, or both, is an open question, as it is hard to disentangle the long-term effects of injuries from long-term effects of the traumatic exposure.After the attacks, the New York State Office of Mental Health collaborated with New York City and county mental health departments to address mental health needs using two related but distinct response strategies.9 The first, named Project Liberty, aimed at the general population consisted of public education concerning traumatic stress reactions and appropriate coping strategies, outreach to all affected communities, and short-term supportive counseling for anyone affected by September 11th. The second response strategy was aimed at a subset of the affected population: individuals whose traumatic symptoms persisted and were of sufficient severity to meet diagnostic criteria for PTSD and/or other mental disorder. From mid-October 2001 through March 2002, Project Liberty staff provided over 42,000 service encounters, representing service to over 91,000 unique individuals. An evaluation of Project Liberty showed that counselors were able to identify which individuals might require more intensive mental health treatment. Overall, about 9% of individuals encountered through Project Liberty were referred for mental health treatment. These individuals experienced about twice as many traumatic symptoms as those not referred, and rates of referral were higher for highly traumatized groups such as families of the deceased and WTC evacuees.9Information on disaster-related factors that may influence long-term quality of life of survivors can inform the development of strategies to ensure the best possible outcome and recovery for seriously injured disaster survivors. The goals of this qualitative study were to 1) fill in the gaps in knowledge concerning the circumstances surrounding the injuries, 2) determine the short and long term mental and physical health effects of being injured, and 3) assess the social and economic impacts of being injured.
Methods
A semi-structured interview script, which was informed by a conceptual model of long-term health impacts in disaster survivors, was used to conduct the interviews. Telephone interviews were conducted on 33 eligible Registry enrollees between March and June 2015 (83% of those contacted by phone agreed to be interviewed). Up to 50 interviews were planned, but saturation10 was reached with 33 interviews and therefore, in order to minimize respondent burden, no further recruitment was conducted. These interviewees met the study criteria eligibility: a) completion of registry survey waves 1, 2, and 3; b) report of sustaining any one or more of five types of injuries on 9/11 (sprain/strain, cut/laceration, burn, fracture, or head injury) on the Registry’s Wave 1 (2002-2003) interview; c) report of being present south of Chambers Street on the morning of 9/11; d) aged 17 years or older on 9/11; e) English language preference; f) and current address in U.S. We maximized representation of persons who either reported multiple types of injuries or more severe types of injuries by including those with head/concussion, burns, or bone fractures or dislocation injuries, while also including persons with less severe types of injuries, such as sprain/strain or lacerations. For the first 10 interviews, we did not recruit persons with a history of probable PTSD, which is defined as attaining a score of 44 or greater on the PCL-171
,
11 in order to assess the degree of distress during the interview that might occur. In subsequent batches we recruited persons with probable PTSD at Waves 1 or 2 and then Wave 3. Recruiters and the interviewer were blinded to the PTSD scores of all participants in order to minimize the risk of interviewer bias.Potential study participants were first sent an invitation letter with a description of the study, its purpose and the benefits and risks of participation. Registry recruitment staff called all potential participants to schedule an interview and to obtain verbal consent prior to conducting the interview. Participants were sent a $50 gift card as compensation for their time.Each interview lasted approximately one hour. The interviewer’s guide was developed by all authors with input from other Registry staff. Table 1 displays topics and sample questions from the guide. All interviews were recorded with enrollee permission and transcribed verbatim by a professional transcriptionist. This study was approved by the institutional review board of the NYC Department of Health and Mental Hygiene.

Ethics StatementThis study was approved by the institutional review board of the NYC Department of Health and Mental Hygiene.Table 1. Interview topic and sample questionsData AnalysisUsing a pre-set list of major themes that were based on the conceptual models embedded in the interview script, two members of the research team read and coded the first five transcripts of the recorded data. The analysis was conducted using the block of data for each of the major categories as described in the interview guide. The researchers then met to achieve consensus on the major themes and sub-themes, and to identify and discuss any new themes that emerged from the data. At this stage, the researchers also agreed upon the terminology that would be used for the themes. For example, originally, one researcher listed “Changes in Work Status” as a separate theme, the two researchers agreed to fold this into the “Lifestyle Impacts” theme. One researcher initially referred to any new health problems as “New Health Problems,” which was then changed to “Current Health Status, Functional Physical Status Impairments and Disability.” Once the new terminology was in place, the two researchers then read the next 5 transcripts to ensure that they were coding using the same terminology and pre-set themes similarly. After thorough discussion of the identified themes by all three researchers, further adjustments to terminology were again made at this point to keep the themes to a manageable number (resulting in the final six themes identified). Disagreements about themes were discussed and resolved among coders until 100% agreement on themes was achieved. Two researchers then reread all 33 transcripts and coded them separately. They then met to compare their results and at this point the third researcher assessed the coding and determined an interrater reliability of 0.97.The authors used thematic analysis12 as the analytic framework to identify themes relevant to participants’ post-9/11 health and mental health (short- and long-term), health care utilization, social support, and everyday functioning. Coders were unaware of the PTSD scores during this analysis phase. The analysis included line-by-line coding of statements and responses by two independent researchers (LMG and RG).13 The researchers reviewed the codes and evaluated their meaning. The coded data were organized to identify themes. These themes were cross-referenced among the coders and percent agreement was determined.
Results
Participant characteristicsDemographic characteristics of the participants are described in Table 2. Over half (57.6%) were male and 48.5% were age 25-44 years on 9/11. The largest proportion (75.8%) of participants was white and 12.1% were Hispanic. Almost half (45.5%) had a college or post-graduate degree. Over half (51.7%) reported an annual household income of over $75,000 in 2002. Almost 40% participated in rescue and recovery work on 9/11. Almost half (48.5%) did not screen positive for probable PTSD on any of the 3 waves, 27.3% had probable PTSD at Wave 1 and/or Wave 2, and 24.2% had probable PTSD at Wave 3. Three-quarters of participants had ‘more’ severe injuries, of these, 69.7% had two or more injuries, and 24.2% were categorized as having ‘less’ severe injuries.
Table 2. Characteristics of participants interviewed (n=33)
As has been previously reported,14 many participants reported delay in seeking health care services after the event. Oftentimes, the delay was quite extended, even when the participant had experienced relatively serious injuries. This was especially common among first responders who tended to dismiss their own injuries so that they could return to duty as soon as possible. They also did not want to “make a big deal of the injury,” as so many fellow responders had been killed. A similar sentiment was also voiced by non-responders; they felt guilty that they had survived and did not want to acknowledge injuries in the face of so many fatalities. To address this issue, recommendations regarding care for all acutely exposed survivors (with or without obvious injuries) should include medical evaluation and treatment, as needed, at the earliest possible time following mass casualty events. The medical evaluation should also include assessment for acute stress response, with follow-up scheduled so that physical health status could be monitored and to identify psychological problems that may manifest at a later time (weeks or months after the event). This follow-up visit would also allow for referral for any specialized medical or psychological treatment. Programs like Project Liberty, started in the weeks after 9/11, should be implemented to provide free public educational and crisis counseling services. This large-scale public health intervention aimed at ameliorating the traumatic stress experienced by tens of thousands of New Yorkers in the disaster area.9 Individuals varied widely in the severity of experienced trauma and associated traumatic reactions and individuals with the most severe reactions were referred to longer-term mental health treatment services.9 Primary care providers now furnish over half of mental health treatment in this country and about 25% of all primary care recipients have diagnosable mental disorders.15 In disaster exposed populations the need for psychological care may rapidly overwhelm the available mental health services, and primary care providers could be a source of mental health treatment after a disaster. In addition, this approach would also allow for an integrated mental health services with physical healthcare in the same location, an approach that has been shown to be highly effective.16As shown in previous studies on 9/11 survivors enrolled in the World Trade Center Health Registry, long-term physical and mental health problems were common.1

20 A novel finding in our study was the extent of extreme social isolation in some participants. The upheaval this event caused in their lives led some survivors to become very socially withdrawn, which then in turn led to further adverse effects on their overall quality of life. In many cases, social isolation in many participants resulted in them being home bound, manifested especially in fearfulness of being out in public or in public spaces. Many participants no longer engaged in activities and/or social events that had previously been enjoyable for them. Extreme fear about leaving the home led to estrangement from their family members and friends. Several became very anxious about their children and spouses leaving the home- especially if they were going to be in crowded places, which also caused problems within the family. Sleep disturbances and chronic pain led to self-medication, which also led many to withdraw from social contact.It was not surprising to find that participants stressed the importance of emotional and social support from friends and family, as high social support and social integration have been shown to decrease the odds of 9/11-related PTSD.21
,
22 An important finding is that some participants said they were only able to talk about their 9/11-experiences with others who had also been there during the attacks. This may indicate a need for group therapy sessions or support groups after a disaster, for both the individual and potentially their family. In cases where the participant did eventually enter mental health care treatment, treatment was often reported to be efficacious, especially if they were able to form a strong therapeutic bond with their therapist. The need for not only effective evidence-based individual mental health care for disaster survivors, but for their families as well, is an important consideration raised by these study findings.Early retirement or disability retirement was commonly reported, many participants were left without important benefits of work. A recent study of WTCHR enrollees found that workers with chronic conditions were more likely to experience early retirement and job loss, and the association was stronger in the presence of PTSD comorbidity.23 A qualitative study of injured survivors of The Station nightclub fire in Rhode Island also found that participants commented on themes of financial stress as well as disruption to their daily lives, such as inability to work.24 Beyond the issue of loss of income, which was very common in our sample, loss of employment eliminated opportunities for workplace socialization and access to employee assistance programs, leading further to social isolation. Moreover, because many firms went out of business, employees no longer even stayed in touch with one another. This was true even for first responders who felt disconnected from their former friends, as they no longer felt part of ‘the team.’ In some cases though, retired first responders formed new bonds with other WTCD retirees.We found that even among those who did not have current PTSD, there was a lack of recovery and diminished quality of life reported. There are a number of possible reasons for this observation. One explanation might be a relatively new phenomenon referred to as “moral injury”.25 There are similarities between reports of ongoing symptoms and sense of isolation in these participants with those reported by returning war veterans. In our study, participants frequently witnessed suffering, horrific and undignified death, and fear for their lives, and the symptoms commonly associated with moral injury (guilt, remorse, and demoralization)25 were also frequently reported by our study participants. Additional studies to assess this phenomenon in disaster survivors, especially survivors of terrorist or mass-shooting atrocities are warranted. Another potential explanation could be that participants have some form of survivor’s guilt. Survivor’s guilt is a mental condition that occurs when a person perceives themselves to have done wrong by surviving a traumatic event when others did not.26 It may be found among survivors of combat, natural disasters, and epidemics.26 In the Diagnostic and Statistical Manual of Mental Disorders V (DSM-V), it is considered an associated descriptive feature of PTSD, described as a persistent negative trauma-related emotion.27 Survivor guilt has also been implicated in the genesis of clinical depression. Although major clinical depression and PTSD are often comorbid diagnoses, guilt may be present or absent in both.28On the other hand, just how participants who demonstrated resiliency were able to do so may be explained by recent work by Richardson (2015) on the role of ‘making sense’ in disaster recovery.29 Programs, such as the docent program at the WTC Tribute Center as described by Richardson, have been shown to help support recovery by allowing survivors to make better sense of their trauma through sharing for posterity their own experiences on that day. This gave them both a sense of purpose and a sense of pride that they could help others.30There is a growing interest in post-traumatic resilience and post-traumatic growth, which can result from devastating, catastrophic events.31 Though there may be a tendency to look to survivors of a traumatic event as victims of a tragedy, future research into long-term outcomes should focus on factors contributing to survivor resiliency and positive outcomes in the face of tragedy.LimitationsThis study focused solely on those injured on 9/11 and thus results reported here may not be representative of other non-inured 9/11 disaster survivors. With only 33 participants, this was a small sample, although we did reach thematic saturation. There was also the risk of recall bias, however, we did have data from 2002-2003 on injuries reported at that time and we also framed the questions on their current recovery and everyday functioning. Also, there is the possibility of self-report bias; participants may have provided responses that they felt were socially acceptable. In spite of the potential limitations inherent in the design and sampling, this exploratory study was appropriate for this stage of inquiry and provided unanticipated avenues for further research.
Conclusions
In this study we were able to identify serious long-term health and mental health effects related to the WTCD. Among those injured, quality of life was seriously and negatively affected. Public health has a responsibility to aid survivors and community members both immediately following a disaster event and, importantly, in the long-term. Because both natural and human-caused disasters are increasing in frequency and severity, communities and government agencies should prepare now with respect to the provision of short and long-term assessment and treatment for victims of these types of events. The full functioning and participation of all members of the community is essential for community resiliency and recovery following disasters.
