KEY WORDS:<br />

Predictors <strong>of</strong> hospital survival <strong>after</strong> emergency department thoracotomy (EDT) are well established, but little is known <strong>of</strong><br />

long-<strong>term</strong> <strong>outcomes</strong> <strong>after</strong> hospital survival. Our primary study objective was to analyze the long-<strong>term</strong> social, cognitive,<br />

functional, and psychological <strong>outcomes</strong> in EDT survivors.<br />

Review <strong>of</strong> our Level I trauma center registry (2000Y2010) revealed that 37 <strong>of</strong> 448 patients survived hospitalization <strong>after</strong><br />

EDT. Demographics and clinical characteristics were analyzed. After attempts to contact survivors, 21 patients or caretakers<br />

were invited to an outpatient study evaluation; 16 were unreachable (none <strong>of</strong> whom were present in the Social Security Death<br />

Index). Study evaluation included demographic and social data and an outpatient multidisciplinary assessment with validated<br />

scoring instruments (Mini-Mental Status Exam, Glasgow Outcome Scores, Timed Get-Up and Go Test, Functional Independence<br />

Measure Scoring, SF-36 Health Survey, and civilian posttraumatic stress disorder checklist).<br />

After extended hospitalization (43 T 41 days), disposition varied (home, 62%; rehabilitation, 32%; skilled nursing facility,<br />

6%), but readmission was common (33%) in the 37 EDT hospital survivors. Of the 21 contacted, 16 completed the study<br />

evaluation, 2 had died, 1 remained in a comatose state, and 2 were available by telephone only. While unemployment (75%),<br />

daily alcohol (50%), and drug use (38%) were common, <strong>of</strong> the 16 patients who underwent the comprehensive, multidisciplinary<br />

outpatient assessment <strong>after</strong> a median <strong>of</strong> 59 months following EDT, 75% had normal cognition and returned to normal activities,<br />

81% were freely mobile and functional, and 75% had no evidence <strong>of</strong> posttraumatic stress disorder upon outpatient screening.<br />

Despite the common belief that EDT survivors <strong>of</strong>ten live with severe neurologic or functional impairment, we have found that<br />

most <strong>of</strong> our sampled EDT survivors had no evidence <strong>of</strong> long-<strong>term</strong> impairment. It is our hope that these results are considered by<br />

physicians making life or <strong>death</strong> decisions regarding the ‘‘futility’’ <strong>of</strong> EDT in our most severely injured patients. (J Trauma<br />

Emergency department thoracotomy; long-<strong>term</strong> <strong>outcomes</strong>; quality <strong>of</strong> life.<br />

Emergency department thoracotomy (EDT) is an established<br />

procedure that has been used to salvage the most critically<br />

injured patients. While the indications and predictors <strong>of</strong> hospital<br />

survival <strong>of</strong> the procedure are well defined, 1Y5 EDT remains<br />

controversial owing to limited survival, perceived risk <strong>of</strong> occupational<br />

exposure by health care workers, and the potential<br />

for salvaging patients with neurologic impairment. 6Y11<br />

Although proper patient selection and strict adherence<br />

to universal precautions may diminish some risk associated<br />

with EDT, the possibility <strong>of</strong> resuscitating a patient with anoxic<br />

encephalopathy must be considered. In the review <strong>of</strong> EDT literature<br />

from 1974 to 1998 by Rhee et al., 2 23 studies reported gross<br />

neurologic outcome in EDT survivors before hospital discharge.<br />

Of the 303 survivors with reported neurologic status, 92.4%<br />

had ‘‘normal’’ neurologic <strong>outcomes</strong> before discharge. 3 Other<br />

reports were less favorable, documenting no neurologically intact<br />

survivors among blunt trauma victims without signs <strong>of</strong> life<br />

in the emergency department (ED) or penetrating trauma patients<br />

without scene signs <strong>of</strong> life. 12,13 In a 10-year review <strong>of</strong><br />

290 EDT patients, Millham et al. 13 reported only 4 <strong>of</strong> their 13<br />

EDT survivors had normal neurologic function during their<br />

hospitalization. To our knowledge however, no previous studies<br />

have evaluated long-<strong>term</strong> cognitive or functional status in EDT<br />

survivors <strong>after</strong> hospital discharge.<br />

Little is known <strong>of</strong> the long-<strong>term</strong> <strong>outcomes</strong> in those that<br />

survive their hospitalization <strong>after</strong> EDT. We hypothesized that<br />

EDT survivors are able to live healthful, productive lives. Our<br />

primary study objective was to analyze the long-<strong>term</strong> cognitive,<br />

functional, and psychological status in EDT survivors to assess<br />

their quality <strong>of</strong> life <strong>after</strong> hospital discharge.<br />

PATIENTS AND METHODS<br />

Temple University Hospital is a state-verified, Level I<br />

Trauma Center in Philadelphia, Pennsylvania. After institutional<br />

review board approval, review <strong>of</strong> the trauma registry<br />

from January 2000 to December 2010 revealed that 37 <strong>of</strong> 448<br />

patients survived their hospitalization <strong>after</strong> EDT. All patients<br />

who underwent EDT immediately upon arrival to the ED,<br />

regardless <strong>of</strong> age or injury mechanism, were included in this<br />

analysis. Patients who underwent ‘‘urgent’’ thoracotomy in the<br />

operating suite were excluded. Indications for EDT included<br />

loss <strong>of</strong> signs <strong>of</strong> life (pupillary response, spontaneous ventilation,<br />

the presence <strong>of</strong> a carotid pulse, measurable or palpable<br />

blood pressure, extremity movement, or any cardiac electrical<br />

activity) within 15 minutes for patients with penetrating<br />

trauma or witnessed cardiopulmonary arrest in patients with<br />

blunt injury.<br />

Demographics and clinical characteristics from the index<br />

hospitalization were analyzed in all 37 EDT hospital survivors.<br />

Measured variables included injury mechanism, anatomic injury,<br />

the presence <strong>of</strong> field and ED signs <strong>of</strong> life, cardiac rhythm,<br />

method <strong>of</strong> prehospital transportation, initial ED Glasgow<br />

Coma Scale (GCS) score, Injury Severity Score (ISS), intensive<br />

care unit (ICU) length <strong>of</strong> stay (LOS), number <strong>of</strong> ventilator<br />

days, hospital LOS, disposition at hospital discharge, and number<br />

<strong>of</strong> readmissions and ED visits <strong>after</strong> index hospitalization.<br />

We then attempted to contact each <strong>of</strong> the 37 hospital<br />

survivors using inpatient, outpatient, and ED medical records,<br />

billing reports, State Prison Registries, and online search engines.<br />

After exhaustive efforts to contact each survivor by telephone<br />

and mail, 21 patients or caretakers were contacted and<br />

invited to participate in an outpatient cognitive and functional<br />

assessment, while 16 hospital survivors were lost to follow-up.<br />

None <strong>of</strong> these 16 patients were present in the Social Security<br />

Death Index. Five <strong>of</strong> the 21 patients or caregivers contacted<br />

were unable to participate in outpatient testing (two died <strong>after</strong><br />

hospital discharge [both unrelated to their injuries or EDTVone<br />

ruptured cerebral aneurysm, one <strong>of</strong> ‘‘natural’’ causes], one was<br />

in a persistent comatose state, two participated in telephone<br />

interviews only). Outpatient evaluations were performed by<br />

both trauma surgery and physical medicine and rehabilitation<br />

staff on the final 16 study patients.<br />

The outpatient assessment began with patient interviews<br />

by trauma faculty using a study questionnaire focused on patient<br />

demographics and social data. Each final study patient<br />

(n = 16) then underwent a comprehensive, multidisciplinary<br />

assessment consisting <strong>of</strong> each <strong>of</strong> the following previously validated<br />

scoring instruments: Mini-Mental Status Exam (MMSE;<br />

normal cognition, Q25 points; mild cognitive impairment,<br />

21Y24 points; moderate impairment, 10Y20 points; severe cognitive<br />

impairment, e9 points), Glasgow Outcome Scoring (GOS;<br />

range from full recovery with resumption <strong>of</strong> normal occupational<br />

and social activities, score <strong>of</strong> 1, to dead, score <strong>of</strong> 5), Timed<br />

Get-Up and Go Test (TGUG) (impaired mobility 920 seconds),<br />

Functional Independence Measure (FIM) Scoring range<br />

from requiring total assistance, score <strong>of</strong> 1, to complete independence,<br />

score <strong>of</strong> 7), civilian posttraumatic stress disorder (PTSD)<br />

checklist (score 956 indicates moderate or severe PTSD), and<br />

the Rand Medical Outcomes Study Short Form-36 Health<br />

Survey (SF-36). To complete the TGUG, the patient is asked to<br />

stand from the sitting position, walk 10 m around an obstacle, and<br />

then return to the sitting position <strong>after</strong> walking 10 m back. The<br />

civilian PTSD checklist evaluates patients for the 17 Diagnostic<br />

and Statistical Manual <strong>of</strong> Mental Disorders, Fourth Edition<br />

(DSM-IV) symptoms <strong>of</strong> PTSD using a validated set <strong>of</strong> questions<br />

and scoring criteria. Each <strong>of</strong> the eight SF-36 component scores<br />

in our study population were compared with US mean scores.<br />

The primary study end point was the long-<strong>term</strong> social, functional,<br />

and psychological <strong>outcomes</strong> in EDT survivors. Means<br />

are accompanied by SDs, and percentages <strong>of</strong> outpatient participants<br />

are accompanied by ranges (assuming that the 16 patients<br />

without follow-up did well and assuming that the 16 patients<br />

without follow-up did poorly).<br />

RESULTS<br />

Thirty-seven (8.3%) <strong>of</strong> the 448 patients who underwent<br />

EDT survived until hospital discharge (Table 1). These 37 EDT<br />

survivors were most <strong>of</strong>ten young (mean [SD], 32 [9] years),<br />

males (92%), with severe injuries (mean [SD] ISS, 31 [24]) by<br />

penetrating mechanisms (gunshot wounds, 65%; stab wounds,<br />

33%). Prehospital transportation in these survivors varied,<br />

with 46% <strong>of</strong> survivors arriving by police, 35% by emergency<br />

medical service (EMS), and 19% by private vehicle. At admission,<br />

most survivors were comatose (mean [SD] GCS<br />

score, 7 [5]) owing to shock. Although both ICU and hospital<br />

LOS were prolonged (26 [26] days and 43 [41] days, respectively),<br />

disposition at discharge was varied (home, 62%; rehabilitation,<br />

32%; skilled nursing facility, 6%), while hospital<br />

readmissions were common (33%) <strong>after</strong> discharge.<br />

Of the 37 EDT hospital survivors, 21 patients or caretakers<br />

were contacted and invited to participate in our outpatient<br />

assessment, and 16 patients were lost to follow-up (Fig. 1).<br />

None <strong>of</strong> these 16 patients who were lost to follow-up were<br />

present in the Social Security Death Index. Of the 21 patients<br />

or caretakers contacted, 2 hospital survivors had died <strong>after</strong><br />

hospital discharge, 1 remained in a persistent comatose state,<br />

and 2 were available for telephone interview only.<br />

Each <strong>of</strong> the remaining 16 long-<strong>term</strong> EDT survivors completed<br />

the full outpatient assessment <strong>after</strong> a mean elapsed time<br />

from EDT until study participation <strong>of</strong> 61 (37) months (median,<br />

59 months). <strong>Long</strong>-<strong>term</strong> EDT survivors were <strong>of</strong>ten single, divorced,<br />

or widowed (81%), with children (81%). Daily alcohol<br />

(50%), illicit drug use (38%), unemployment (75%),<br />

and incarceration (13%) were common in those who underwent<br />

the full social, cognitive, functional, and psychological<br />

outpatient assessment.<br />

Cognition in long-<strong>term</strong> EDT survivors was assessed with<br />

the Folstein MMSE and GOS. The MMSE assesses orientation,<br />

word recall, attention and calculation, language abilities, and<br />

visual-spatial ability on a 30-point scale. While the mean (SD)<br />

and median MMSE scores were 26 (5) and 28, respectively,<br />

75% (range, 38Y88%) <strong>of</strong> our survivors had normal cognition,<br />

13% (range, 6Y56%) had moderate cognitive impairment, and<br />

13% (range, 6Y56%) had severe cognitive impairment (Fig. 2A).<br />

Cognition and capacity to return to normal occupational and<br />

activities were evaluated with the GOS. Similar to the MMSE<br />

distribution, GOS (Fig. 2B) demonstrated that 75% (range,<br />

38Y88%) <strong>of</strong> our survivors had good recovery (GOS, 1), 13%<br />

(range, 6Y56%) had moderate disability (GOS, 2), and only<br />

13% (range, 6Y56%) had severe disability (GOS, 3).<br />

The functional <strong>outcomes</strong> <strong>of</strong> our EDT survivors were<br />

analyzed with the FIM score and TGUG. The mean (SD) and<br />

median FIM score <strong>of</strong> our survivors was 6.3 (0.1) and 7, respectively,<br />

with a range from 6.2 to 6.4 in each subactivity<br />

mean FIM score (Fig. 3A). The TGUG, evaluating mobility<br />

and independence, de<strong>term</strong>ined that 81% (range, 41Y91%) <strong>of</strong><br />

study participants were freely mobile, 6% (range, 3Y53%)<br />

had mild or moderately impaired mobility, and 13% (range,<br />

6Y56%) were severely impaired and required wheelchairs<br />

(Fig. 3B).<br />

Patients with any type <strong>of</strong> long-<strong>term</strong> follow-up (full outpatient<br />

assessment, telephone interview with patient, caretaker,<br />

or family member) were then compared with respect to<br />

degree <strong>of</strong> long-<strong>term</strong> cognitive or functional impairment <strong>after</strong><br />

EDT (Table 2). While patients without cognitive or functional<br />

impairment (n = 11) were younger (28 [6] years vs. 39 [11]<br />

years, p = 0.007) and less <strong>of</strong>ten transported by police (27% vs.<br />

80%, p = 0.030) than those with any evidence <strong>of</strong> impairment<br />

(n = 10), there were no differences in injury mechanism, anatomic<br />

injury location, injury severity, signs <strong>of</strong> life, cardiac<br />

rhythm, or GCS score (all p 9 0.05) between these groups.<br />

Psychological outcome and quality <strong>of</strong> life were also<br />

analyzed. EDT survivors were screened for PTSD using the<br />

PTSD Civilian ChecklistVa previously validated screening<br />

tool that demonstrated 25% (range, 13Y63%) <strong>of</strong> the present<br />

study participants met the criteria for PTSD. The Rand Medical<br />

Outcomes Study Short Form-36 Health Survey (SF-36)<br />

was used to examine the long-<strong>term</strong> quality <strong>of</strong> life in our<br />

EDT survivors as compared with validated national mean<br />

scores (United States, 1998) for each <strong>of</strong> the eight SF-36 components<br />

(Table 1).<br />

In summary, <strong>of</strong> the 16 patients who underwent the comprehensive,<br />

multidisciplinary outpatient assessment <strong>after</strong> a<br />

median <strong>of</strong> 59 months following EDT, 75% had normal cognition<br />

and returned to normal activities, 81% were freely<br />

mobile and functional, and 75% had no evidence <strong>of</strong> PTSD<br />

upon outpatient screening.<br />

DISCUSSION<br />

We have de<strong>term</strong>ined that <strong>of</strong> the 8.3% <strong>of</strong> patients who<br />

survived hospitalization <strong>after</strong> EDT, the majority <strong>of</strong> our sampled<br />

EDT survivors had no evidence <strong>of</strong> cognitive, functional,<br />

or psychological long-<strong>term</strong> impairment. To our knowledge,<br />

this study is the first to evaluate the long-<strong>term</strong> status <strong>of</strong> EDT<br />

survivors <strong>after</strong> hospital discharge. While some physicians<br />

may avoid the potential life-saving procedure for fear <strong>of</strong> salvaging<br />

a severely impaired patient, careful analysis however<br />

<strong>of</strong> previous reports describing either critically ill ICU patients,<br />

While no previous studies have evaluated the long-<strong>term</strong><br />

<strong>outcomes</strong> <strong>of</strong> patients <strong>after</strong> EDT, long-<strong>term</strong> <strong>outcomes</strong> and<br />

quality <strong>of</strong> life <strong>after</strong> critical illness with a prolonged ICU course<br />

have been described. 14,15 Oeyen et al. 14 performed a systematic<br />

review <strong>of</strong> the literature regarding quality <strong>of</strong> life <strong>after</strong> intensive<br />

care. In the meta-analysis <strong>of</strong> 53 studies, critically ill patients<br />

uniformly had a lower quality <strong>of</strong> life compared with an age- and<br />

sex-matched population 1 year <strong>after</strong> intensive care. Despite<br />

a primarily young and healthy population, severe trauma patients<br />

experienced significant reductions in both physical and<br />

Twenty-one patients or caretakers were contacted, 2 hospital survivors had died <strong>after</strong><br />

hospital discharge, 1 remained in a persistent comatose state, 2 were available for telephone<br />

interview only, and 16 long-<strong>term</strong> EDT survivors completed the full outpatient<br />

assessment.<br />

psychosocial quality-<strong>of</strong>-life measures and less <strong>of</strong>ten returned to<br />

work. Timmers et al. 15 performed a prospective observational<br />

cohort study <strong>of</strong> surviving surgical ICU patients during a 5-year<br />

period to quantify their quality <strong>of</strong> life. Trauma patients more<br />

<strong>of</strong>ten (odds ratio, 2.5Y3.5) had problems with mobility, selfcare,<br />

usual activities, and cognition than other surgical patients.<br />

After a mean ICU LOS <strong>of</strong> 26 days, our findings in EDT<br />

patients are concordant with these studies <strong>of</strong> general surgical<br />

ICU patients.<br />

<strong>Long</strong>-<strong>term</strong> outcome <strong>after</strong> TBI has been well studied. 16Y18<br />

While our EDT survivors were primarily victims <strong>of</strong> penetrating<br />

trauma without TBI, a review <strong>of</strong> reports describing<br />

long-<strong>term</strong> outcome <strong>after</strong> TBI does illustrate the negative impact<br />

injury has on another subset <strong>of</strong> the population. Livingston<br />

et al. 17,18 measured functional status before hospital<br />

discharge and <strong>after</strong> a 2 year follow-up using both GOS and<br />

FIM tests. With lower FIM scores and greater unemployment<br />

rate, Livingston et al. 17,18 concluded that TBI patients<br />

requiringprolongedICUcaremayhave‘‘afateworsethan<br />

<strong>death</strong>.’’ Importantly, age was an important de<strong>term</strong>ining factor<br />

in long-<strong>term</strong> <strong>outcomes</strong> in each <strong>of</strong> these studies. Increasing<br />

age was associated with long-<strong>term</strong> impairment <strong>after</strong> EDT in<br />

the present report also. Importantly, the EDT population consists<br />

primarily <strong>of</strong> young males. With a mean age <strong>of</strong> 32 years<br />

in our EDT survivors, EDT patients are <strong>of</strong>ten younger, are<br />

stronger, and have a greater opportunity for recovery than their<br />

elder, critically injured counterparts.<br />

The long-<strong>term</strong> <strong>outcomes</strong> <strong>after</strong> general trauma have also<br />

demonstrated persistent cognitive, functional, and psychological<br />

issues affecting the quality <strong>of</strong> life in survivors. 19Y25<br />

Holbrook et al. 20 reported similar results to the present study<br />

in 6-month follow-up in general trauma patients. The authors<br />

de<strong>term</strong>ined that hospital LOS greater than 7 days, ICU LOS<br />

greater than 4 days, and ISS <strong>of</strong> greater than 10 were factors<br />

that negatively impacted <strong>outcomes</strong>. 23 Despite the presence<br />

<strong>of</strong> these characteristics in each <strong>of</strong> our EDT survivors, most <strong>of</strong><br />

the sampled survivors had no evidence <strong>of</strong> long-<strong>term</strong> cognitive<br />

or functional impairment.<br />

While no difference in ISS was detected between contacted<br />

patients with no long-<strong>term</strong> impairment or any impairment,<br />

cognitively or functionally impaired patients were more<br />

likely to have been transported by police (80%) compared with<br />

unimpaired EDT survivors (27%). This finding merits attention<br />

and two possible explanations. Cardiopulmonary resuscitation<br />

is seldom performed by police when transporting critically<br />

injured patients in PhiladelphiaVa phenomena that may encourage<br />

anoxic encephalopathy in this population. Importantly,<br />

patients with any degree <strong>of</strong> long-<strong>term</strong> cognitive or functional<br />

impairment were compared. Second, we have previously<br />

reported that hospital survival <strong>after</strong> EDTis adversely affected by<br />

prehospital EMS resuscitation and procedures. 26 Another<br />

plausible explanation for the association between police transport<br />

and impairment is that although hospital survival is improved<br />

<strong>after</strong> minimal prehospital intervention in this population,<br />

some hospital EDT survivors may experience long-<strong>term</strong> cognitive<br />

and functional impairment.<br />

The quality-<strong>of</strong>-life and psychological impact <strong>of</strong> major<br />

trauma on survivors also merit attention. Soberg et al. 23 used<br />

the SF-36 to analyze long-<strong>term</strong> <strong>outcomes</strong> 2 years <strong>after</strong> severe,<br />

polysystem injury. Similar to our findings, severely injured<br />

patients fared worse than the general population in SF-36 measures.<br />

With 25% (range, 13Y63%) <strong>of</strong> our EDT survivors screening<br />

positive for PTSD, better recognition and long-<strong>term</strong> therapy<br />

may improve <strong>outcomes</strong>. Although infrequently reported, the<br />

prevalence <strong>of</strong> PTSD in our long-<strong>term</strong> EDT survivors is consistent<br />

with other series describing PTSD <strong>after</strong> major trauma. 19,20,27<br />

Holbrook et al. 19 reported <strong>outcomes</strong> 18 months <strong>after</strong> injury<br />

and discovered high rates <strong>of</strong> depression and PTSD (35%)V<br />

factors that were independently associated with poor functional<br />

<strong>outcomes</strong> in injury survivors.<br />

We recognize our study limitations. This study represents<br />

the analysis <strong>of</strong> long-<strong>term</strong> <strong>outcomes</strong> in EDT survivors<br />

primarily <strong>after</strong> penetrating injury (36 <strong>of</strong> 37 survivors) from a<br />

single institution, and results may not be applicable to other<br />

injury mechanisms or other trauma systems. Study participation<br />

was not uniform as 16 <strong>of</strong> 37 EDT hospital survivors were<br />

completely lost to follow-up. Lastly, our study lacks a comparison<br />

or control group. While a ‘‘non-EDT’’ control group<br />

with similar critical injuries is not possible owing to practical<br />

and ethical considerations, we have compared our findings to<br />

those <strong>of</strong> previous reports describing long-<strong>term</strong> <strong>outcomes</strong> in<br />

general trauma patients have discovered similar results.<br />

Despite the common belief that EDT survivors <strong>of</strong>ten live<br />

with severe neurologic or functional impairment, we have<br />

found that most <strong>of</strong> our sampled EDT survivors had no evidence<br />

<strong>of</strong> long-<strong>term</strong> impairment. It is our hope that these results<br />

are considered by physicians making life or <strong>death</strong> decisions<br />

regarding the ‘‘futility’’ <strong>of</strong> EDT in our most severely injured<br />

patients. However, the potential for severe long-<strong>term</strong> impairment<br />

<strong>after</strong> EDT should not be overlooked. Similar to other<br />

critically injured trauma populations, survivors <strong>of</strong> EDT also<br />

face significant challenges <strong>after</strong> hospital discharge. While additional<br />

study is required, more rigorous outpatient follow-up<br />

may further improve long-<strong>term</strong> <strong>outcomes</strong> in EDT survivors.<br />
