ICU Readmission in Injured Older Adults: Modifiable Risk Factors and Implications.

BACKGROUND: Prior evaluations of ICU readmission among injured older adults have inconsistently identified risk factors, with findings limited by use of sub-analyses and small sample sizes. This study aimed to identify risk factors for and implications of ICU readmission in injured older adults. METHODS: This retrospective, single-center cohort study was conducted at a High-Volume Level 1 Trauma Center and included injured older adult patients (>65 years old) requiring at least one ICU admission during hospitalization between 2013-2018. Patients who died <48 hours of admission were excluded. Exposures included patient demographics and clinical factors. The primary outcome was ICU readmission. Multi-variable regression was used to identify risk factors for ICU readmission. RESULTS: 6,691 injured adult trauma patients were admitted from 2013-2018, 55.4% (n = 3,709) of whom were admitted to the ICU after excluding early deaths. Of this cohort, 9.1% (n = 339) were readmitted to the ICU during hospitalization. Readmitted ICU patients had a higher median Injury Severity Score (21 (IQR: 14-26) vs 16 (IQR: 10-24)), with similar mechanisms of injury between the two groups. Readmitted ICU patients had a significantly higher mortality (19.5%) compared to single ICU admission patients (9.9%) (p < 0.001) and higher rates of developing any complication, including delirium (61% vs 30%, p < 0.001). On multivariable analysis, the factors associated with the highest risk of readmission were delirium (RR = 2.6, 95% CI 2.07 - 3.26) and aspiration (RR = 3.04, 95% CI 1.67- 5.54). More patients in the single ICU admission cohort received comfort-focused care at the time of their death as compared to the ICU readmission cohort (93% vs 85%, p = 0.035). CONCLUSIONS: Readmission to the ICU is strongly associated with higher mortality for injured older adults. Efforts targeted at preventing respiratory complications and delirium in the geriatric trauma population may decrease the rates of ICU readmission and related mortality risk. LEVEL OF EVIDENCE: III/Epidemiologic.

Long-term health-related quality of life and independence among older survivors of serious injury.

BACKGROUND: Little is known about the recovery experiences of older trauma intensive care unit (TICU) survivors and the relationship between geriatric trauma care and long-term functional ability and health-related quality of life (HRQOL). METHODS: We conducted a prospective cohort study of 218 patients (age, ≥65 years) admitted to a Level 1 regional trauma center TICU before versus after implementation of a geriatric care bundle with protocolized geriatrics consultations (Geri-T). Survivors or their proxies were interviewed approximately 1 year after hospitalization. Outcomes included the Katz Index of Independence in Activities of Daily Living (ADLs), Lawton Instrumental Activities of Daily Living (IADLs), and EQ-5D-5L HRQOL survey. Two investigator-developed questions regarding recovery experiences were included. Differences in outcomes among survivors admitted before versus after Geri-T were analyzed using multivariable linear regression. Responses to questions about recovery experiences were qualitatively assessed using content analysis. RESULTS: We reached 67% (146/218) of hospital survivors or their proxies across both groups; 126 patients were still alive and completed the survey. Mean age was 76 (SD, 8), 36% were female, and 90% were independent with ADLs preinjury. At follow-up, independence with ADLs was 76% and IADLs was 63%. The mean EQ-5D-5L index score was 0.78 (SD, 0.18). Most patients (65%) reported having not returned to preinjury functional status. Neither functional ability or HRQOL differed significantly among patients admitted before versus after Geri-T. Content analysis of open-ended questions revealed themes of activity limitations, persistent pain, and cognitive dysfunction. CONCLUSION: Nearly one-fifth of TICU survivors experienced loss of ADL function 1 year after injury, and most reported having not returned to preinjury functional status. Nonetheless, patient-reported HRQOL was comparable to age-adjusted norms. Geri-T was not associated with differences in HRQOL or functional ability. Survivors reported persistent difficulty with activities beyond those of daily living, pain, and cognition. LEVEL OF EVIDENCE: Prognostic and Epidemiologic, Level III.

Interpersonal violence affecting the pediatric population: Patterns of injury and recidivism.

PURPOSE: We aim to describe interpersonal violence-related injury patterns in the pediatric trauma population and to identify predictors of recidivism. METHODS: In this retrospective analysis from a single institution, we included pediatric patients (≤17 years) treated (2006-2020) for traumatic injury related to interpersonal violence (IPV). Patient characteristics were compared among mechanism types and between recidivists and non recidivists using two sample t-tests, Wilcoxon rank-sum tests, and Pearson's chi-squared. Multivariate analysis was performed using logistic regression to identify predictors of repeat injury. RESULTS: We identified 635 pediatric patients who sustained injuries owning to IPV: firearm (N = 266), assault (stab/blunt; N = 243), and abuse (N = 126). The average age of the firearm, assault, and abuse groups was 15.5, 14.7, and 1.1 years (SD = 2.2, 3.4, 2.4 years), respectively. Majority of the overall cohort was male (77.5%) and publicly- or un insured (67.8%), with 28.0% being Black. Of the 489 firearm and assault patients who survived the first injury, 30 (6.1%) had repeat injury owning to IPV requiring treatment at our center with a median time of 40 months (IQR 17-62 months) between first and second injury. The majority of recidivists (83.3%) were victims of gun violence whereas the distribution between assault and firearm in the non recidivists was more even at 51 and 49%, respectively (p < 0.001). Eighteen (60.0%) of the recidivist patients had the same mechanism between the first and second injury. In the logistic regression analysis, Black race and firearm injury were associated with greater than 3-fold higher likelihood of repeat injury compared to white race after adjusting for age, sex, insurance, and child opportunity index. CONCLUSIONS: We found that survivors of firearm injuries and assault comprise a vulnerable patient cohort at risk for repeat injury, and Black race is an independent predictor of repeat injury owning to IPV. These findings provide guidance for developing violence prevention programs. TYPE OF STUDY: Retrospective Comparative Study LEVEL OF EVIDENCE: Level III.

Making your geriatric and palliative programs a strength: TQIP guideline implementation and the VRC perspective.

BACKGROUND: Older patients compose approximately 30% of trauma patients treated in the USA but make up nearly 50% of deaths from trauma. To help standardize and elevate care of these patients, the American College of Surgeons (ACS) Trauma Quality Improvement Program's best practice guidelines for geriatric trauma management was published in 2013 and that for palliative care was published in 2017. Here, we discuss how palliative care and geriatrics quality metrics can be tracked and used for performance improvement and leveraged as a strength for trauma verification. METHODS: We discuss the viewpoint of the ACS Verification, Review, and Consultation and three case studies, with practical tips and takeaways, of how these measures have been implemented at different institutions. RESULTS: We describe the use of (1) targeted educational initiatives, (2) development of a consultation tool based on institutional resources, and (3) application of a nurse-led frailty screen. DISCUSSION: Specialized care and attention to these vulnerable populations is recommended, but the implementation of these programs can take many shapes.Level of evidence V.

Top Ten Tips Palliative Care Clinicians Should Know About Trauma and Emergency Surgery.

There is growing interest in, and need for, integrating palliative care (PC) into the care of patients undergoing emergency surgery and those with traumatic injury. Thus, PC consults for these populations will likely grow in the coming years. Understanding the nuances and unique characteristics of these two acutely ill populations will improve the care that PC clinicians can provide. Using a modified Delphi technique, this article offers 10 tips that experts in the field, based on their broad clinical experience, believe PC clinicians should know about the care of trauma and emergency surgery patients.

Use of regional analgesia and risk of delirium in older adults with multiple rib fractures: An Eastern Association for the Surgery of Trauma multicenter study.

BACKGROUND: Single-center data demonstrates that regional analgesia (RA) techniques are associated with reduced risk of delirium in older patients with multiple rib fractures. We hypothesized that a similar effect between RA and delirium would be identified in a larger cohort of patients from multiple level I trauma centers. METHODS: Retrospective data from seven level I trauma centers were collected for intensive care unit (ICU) patients 65 years or older with ≥3 rib fractures from January 2012 to December 2016. Those with a head and/or spine injury Abbreviated Injury Scale (AIS) score of ≥ 3 or a history of dementia were excluded. Delirium was defined as one positive Confusion Assessment Method for the Intensive Care Unit score in the first 7 days of ICU care. Poisson regression with robust standard errors was used to determine the association of RA (thoracic epidural or paravertebral catheter) with delirium incidence. RESULTS: Data of 574 patients with a median age of 75 years (interquartile range [IQR], 69-83), Injury Severity Score of 14 (IQR, 11-18), and ICU length of stay of 3 days (IQR, 2-6 days) were analyzed. Among the patients, 38.9% were women, 15.3% were non-White, and 31.4% required a chest tube. Regional analgesia was used in 19.3% patients. Patient characteristics did not differ by RA use; however, patients with RA had more severe chest injury (chest AIS, flail segment, hemopneumothorax, thoracostomy tube). In univariate analysis, there was no difference in the likelihood of delirium between the RA and no RA groups (18.9% vs. 23.8% p = 0.28). After adjusting for age, sex, Injury Severity Score, maximum chest AIS, thoracostomy tube, ICU length of stay, and trauma center, RA was associated with reduced risk of delirium (incident rate ratio [IRR], 0.65; 95% confidence interval [CI], 0.44-0.94) but not with in-hospital mortality (IRR, 0.42; 95% CI, 0.14-1.26) or respiratory complications (IRR, 0.70; 95% CI, 0.42-1.16). CONCLUSION: In this multicenter cohort of injured older adults with multiple rib fractures, RA use was associated with a 35% lower risk of delirium. Further studies are needed to standardize protocols for optimal pain management and prevention of delirium in older adults with severe thoracic injury.

Balloons up: shorter time to angioembolization is associated with reduced mortality in patients with shock and complex pelvic fractures (original study).

BACKGROUND: Angioembolization has been the gold standard for management of pelvic arterial bleeding, but applicability has been limited by delays in access at many trauma centers. We hypothesized that a quality improvement program to reduce time to start of angiography would be associated with lower in-hospital mortality in patients with pelvic fractures and shock. METHODS: Retrospective study of adults with a pelvic fracture and vital signs consistent with shock admitted to a level I trauma center after the initiation of a quality improvement project to reduce the time to angioembolization (2012 to 2016). Time from admission to procedure start for hemorrhage control was examined based on destination and time of day. In-hospital mortality was the primary outcome and was compared with US benchmarks in the literature. RESULTS: The study group included 424 patients with a mean Injury Severity Score of 41±14. Of these, 212 (50%) responded to resuscitation and were admitted to the intensive care unit; 143 (34%) patients went directly to interventional radiology (IR) with a median time to start of angiography of 86 minutes (IQR 66 to 116); and 69 (16%) patients went directly to the OR with a median time to start of operation of 52 minutes (IQR 37 to 73). There were no significant differences in time to procedures based on time of day or transfer status. In-hospital mortality for patients in shock on admission was 15%. DISCUSSION: Patients with pelvic fracture and hemorrhagic shock, with a median time to angioembolization of <90 min, had a lower in-hospital mortality compared with published US benchmarks. These times were achieved by protocolization of pelvic fracture management that includes expeditious mobilization of the IR team, bypassing the CT scanner, and institutional quality metrics for compliance.

Decreased Risk of Delirium With Use of Regional Analgesia in Geriatric Trauma Patients With Multiple Rib Fractures.

OBJECTIVE: The aim of this study was to examine the risk of delirium in geriatric trauma patients with rib fractures treated with systemic opioids compared with those treated with regional analgesia (RA). SUMMARY OF BACKGROUND DATA: Delirium is a modifiable complication associated with increased morbidity and mortality. RA may reduce the need for opioid medications, which are associated with delirium in older adults. METHODS: Cohort study of patients ≥65 years admitted to a regional trauma center from 2011 to 2016. Inclusion factors were ≥ 3 rib fractures, blunt trauma mechanism, and admission to intensive care unit (ICU). Exclusion criteria included head AIS ≥3, spine AIS ≥3, dementia, and death within 24 hours. The primary outcome was delirium positive ICU days, defined using the CAM-ICU assessment. Delirium incident rate ratios (IRRs) and 95% confidence intervals (95% CIs) were estimated using generalized linear mixed models with Poisson distribution and robust standard errors. RESULTS: Of the 144 patients included in the study, 27 (19%) received Acute Pain Service consultation and RA and 117 (81%) received opioid-based systemic analgesia. Patients with RA had more severe chest injury than those without. The risk of delirium decreased by 24% per day per patient with use of RA (IRR 0.76, 95% CI 0.61 to 0.96). Individual opioid use, as measured in daily morphine equivalents (MEDs), was significantly reduced after initiation of RA (mean difference -7.62, 95% CI -14.4 to -0.81). CONCLUSION: Although use of RA techniques in geriatric trauma patients with multiple rib fractures was associated with higher MED, opioid use decreased after RA initiation and Acute Pain Service consultation, and the risk of delirium was lower.

In vitro effects of the BH3 mimetic, (-)-gossypol, on head and neck squamous cell carcinoma cells.

PURPOSE: Bcl-xL overexpression is common in head and neck squamous cell carcinomas (HNSCC) and correlates with resistance to chemotherapy. Thus, a nonpeptidic, cell-permeable small molecule that mimics the BH3 domain of proapoptotic proteins may inhibit Bcl-xL function and have therapeutic potential for HNSCC by overcoming drug-resistance. (-)-Gossypol, the levorotatory isomer of a natural product isolated from cottonseeds and roots, was recently discovered to bind to the BH3 binding groove of Bcl-xL and Bcl-2. EXPERIMENTAL DESIGN: We investigated the in vitro effects of (-)-gossypol on HNSCC cell lines as well as on fibroblast and keratinocyte cultures by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cell survival assays and assessed the results with respect to Bcl-2 family protein expression. RESULTS: We observed dose-dependent growth inhibition of 10 HNSCC cell lines at biologically achievable doses (2.5-10 micromol/L). (-)-Gossypol doses required to inhibit the growth of human fibroblast cell lines by 50% were 2- to 10-fold higher than for HNSCC cell lines. To inhibit human oral keratinocyte growth by 50%, (-)-gossypol concentrations were 2-to 3-fold higher than for HNSCC cell lines. CONCLUSIONS: There is a direct correlation between Bcl-xL-to-Bcl-xS ratios and sensitivity to (-)-gossypol. This agent induced apoptosis in a much higher proportion of cells with wild-type p53. Importantly, cell lines resistant to cisplatin were very sensitive to (-)-gossypol. These results demonstrate that (-)-gossypol has potent antitumor activity in HNSCC in vitro. This agent may be developed as a novel therapeutic agent for HNSCC, either alone or in combination with existing chemotherapeutic agents.
