Return to work following injury: the role of economic, social, and job-related factors.

OBJECTIVES This study examined factors influencing return to work (RTW) following severe fracture to a lower extremity. METHODS This prospective cohort study followed 312 individuals treated for a lower extremity fracture at 3 level-1 trauma centers. Kaplan-Meier estimates of the proportion of RTW were computed, and a Cox proportional hazards model was used to examine the contribution of multiple risk factors on RTW. RESULTS Cumulative proportions of RTW at 3, 6, 9, and 12 months post-injury were 0.26, 0.49, 0.60, and 0.72. After accounting for the extent of impairment, characteristics of the patient that correlated with higher rates of RTW included younger age, higher education, higher income, the presence of strong social support, and employment in a white-collar job that was not physically demanding. Receipt of disability compensation had a strong negative effect on RTW. CONCLUSIONS Despite relatively high rates of recovery, one quarter of persons with lower extremity fractures did not return to work by the end of 1 year. The analysis points to subgroups of individuals who are at high risk of delayed RTW, with implications for interventions at the patient, employer, and policy levels.

Abdominal injuries without hemoperitoneum: a potential limitation of focused abdominal sonography for trauma (FAST)

BACKGROUND Focused abdominal sonography for trauma (FAST) relies on hemoperitoneum to identify patients with injury. Blunt trauma victims (BTVs) with abdominal injury, but without hemoperitoneum, on admission are at risk for missed injury. METHODS Clinical, radiologic, and FAST data were collected prospectively on BTVs over a 12-month period. All patients with FAST-negative for hemoperitoneum were further analyzed. Examination findings and associated injuries were evaluated for association with abdominal lesions. RESULTS Of 772 BTVs undergoing FAST, 52 (7%) had abdominal injury. Fifteen of 52 (29%) had no hemoperitoneum by admission computed tomographic scan, and all had FAST interpreted as negative. Four patients with splenic injury underwent laparotomy. Six other patients with splenic injury and five patients with hepatic injury were managed nonoperatively. Clinical risk factors significantly associated with abdominal injury in BTVs without hemoperitoneum include: abrasion, contusion, pain, or tenderness in the lower chest or upper abdomen; pulmonary contusion; lower rib fractures; hemo- or pneumothorax; hematuria; pelvic fracture; and thoracolumbar spine fracture. CONCLUSIONS Up to 29% of abdominal injuries may be missed if BTVs are evaluated with admission FAST as the sole diagnostic tool. Consideration of examination findings and associated injuries should reduce the risk of missed abdominal injury in BTVs with negative FAST results.

Ligamentous Injuries of the Cervical Spine in Unreliable Blunt Trauma Patients: Incidence, Evaluation, and Outcome

BACKGROUND The potential for ligamentous injury of the cervical spine (C-spine) may mandate prolonged neck immobilization via a hard cervical collar in the blunt trauma victim (BTV) with altered sensorium. We investigated the incidence of ligamentous C-spine injuries, and whether applying (post hoc) the practice management guidelines from the Eastern Association for the Surgery of Trauma (three radiograph views plus computed tomographic scan of C1-C2) would have detected the injuries. METHODS The study was a 3-year retrospective review of BTVs admitted to the states Primary Adult Resource Center for trauma from 1996 to 1998. Unreliable patients were defined as those with admission Glasgow Coma Scale score < 15. A rigorous algorithm to clear the C-spine was used. Pure ligamentous C-spine injury was defined as a C-spine having abnormal anatomic alignment, dislocation, subluxation, or listhesis, but without fracture. Demographics, diagnostic studies, presence of neurologic deficit, therapy, survival, and disposition were analyzed. RESULTS There were 14,577 BTVs with 614 (4.2%) patients having C-spine injury. There were 2,605 (18%) unreliable patients, with 143 (5.5%) of these having C-spine injury, 129 (90%) having fracture and 14 (10% of BTVs; 0.5% of unreliable patients) having no fracture. Of the 14 unreliable patients with pure ligamentous C-spine injury, 13 had initial diagnosis by supine cross-table lateral radiograph. The one exception had a normal three-view radiographic series, but atlanto-occipital dislocation was diagnosed by computed tomographic scan. Eight patients had upper level injury (C0-C4) and six were lower (C4-C7). Four patients died within 30 minutes after admission, 4 underwent cervical fusion, and 6 were treated with collar only. Five (50%) of the survivors had no apparent neurologic deficit attributed to the C-spine at admission. Nine patients remained institutionalized after discharge and one was discharged home. CONCLUSION Ligamentous injuries without fracture of the C-spine are rare. Application of the practice management guidelines developed by the Eastern Association for the Surgery of Trauma for identifying C-spine instability is effective and should facilitate early removal of the cervical collar in unreliable patients.

Long-term outcomes after lower extremity trauma

Previous studies have shown that over one-quarter of patients who were working before a severe lower extremity fracture had not returned to work by 12 months after injury. Disabilities also persisted in household management, recreation, and social interaction. The objective of this study was to determine whether recovery extended beyond 12 months. Three hundred nineteen patients who were previously working and were treated at three level I trauma centers for a severe lower extremity fracture were prospectively followed at 3, 6, and 12 months after injury. Patients were queried at each follow-up about their work status and completed the Sickness Impact Profile (SIP) at 6 and 12 months. The SIP is a widely used and well validated measure of general health status; it was used in this study to measure functional recovery across several domains of daily living. Patients who had not recovered by 12 months (i.e., 204 who were not working, working with limitations, or had limitations in performing other daily activities as measured by elevated scores on the SIP) were contacted again at 30 months and asked to complete an interview and the SIP. At 30 months, an estimated 82% of the study patients had returned to work (compared to 72% at 12 months). SIP scores improved only slightly from 6.4 at 12 months to 5.7 at 30 months. At 30 months, 64% of the patients had no disability (SIP scores less than 4), 17% had mild disability (SIP scores of 4 to 9), 12% had moderate disability (SIP scores of 10 to 19), and 7% had severe disability (SIP scores of 20 or higher). Although the majority of patients with persistent disabilities at 30 months had residual physical impairments at 12 months, the extent of impairment did not fully explain why some people had and had not recovered at 30 months after injury. The results confirm those of other studies that conclude that overall, outcomes after serious trauma are good when appropriate trauma and rehabilitation care are rendered. However, a minority of patients still report limitations at 30 months after injury, with one-fifth not returning to work.

Physical impairment and functional outcomes six months after severe lower extremity fractures

To determine functional outcomes after lower extremity fracture (LEF), a prospective follow-up study of patients admitted to three level I trauma centers for treatment of unilateral LEFs was conducted. In this paper we describe outcomes at 6 months after discharge from the initial hospitalization and examine the relationship between impairment and disability. A total of 444 patients met the entry criteria for the study. Of these 376 (85%) were successfully located and interviewed at 6 months; 302 (68%) returned to the trauma center at 6 months for a clinical assessment by a physical therapist. Study patients were predominantly young (mean age = 32.4), white (72%) men (70%) who were working before the injury (77%). The fractures resulted primarily from motor vehicle crashes (71%); mean hospital LOS was 12 days. Disability was measured using the Sickness Impact Profile (SIP), a well validated patient assessment of health status. The overall SIP score averaged for all patients was 10.2, denoting a moderate level of dysfunction or disability. Analysis of the 12 subscores that constitute the SIP indicate particularly high scores for ambulation (16.7 postdischarge vs. 1.2 preinjury), sleep and rest (14.0 vs. 5.1), emotional behavior (10.5 vs. 2.2), home management (15.1 vs. 2.6), recreation and pastimes (19.0 vs. 4.4), and most notably, work (33.2 vs. 8.3). Further analysis of the subgroup of patients working before the injury shows that 48% had returned to work at 6 months. Correlations between lower extremity impairment (range of motion, muscle strength, and pain) and the ambulation subscore of the SIP were high. However, correlations between impairment and more global areas of activity such as home management, work, and recreation were considerably lower. These results suggest that other factors, over and above the extent of physical impairment, significantly influence broader disability outcomes such as return to work. Further research is needed to define these factors so that effective interventions after acute care can be identified and appropriately targeted.

SAFETY BELT RESTRAINTS AND COMPARTMENT INTRUSIONS IN FRONTAL AND LATERAL MOTOR VEHICLE CRASHES: MECHANISMS OF INJURIES, COMPLICATIONS, AND ACUTE CARE COSTS

A 3-year prospective study examined 76 frontal (F) and 45 lateral (L) motor vehicle crash (MVC) patients with regard to seatbelt restraint use and occupant compartment contact and intrusion injuries. These 121 MVC victims with multiple injuries (39 belted [B] and 82 non-belted [NB]), admitted to a level I trauma center, were studied by accident reconstruction and medical data analysis. They had a MVC mean impact velocity (delta V) of 30 +/- 11 mph and an injury Severity Score of 29 +/- 12. Proper restraint use reduced brain injury in F MVCs (30% FB vs. 47% FNB) but had no effect in L MVCs (63% LB vs. 30% FB [p < 0.06]). Belt use did not protect against lung, liver, spleen, pelvis, or lower extremity (LE) injury. These appeared to be more a function of crash direction, with LE injuries higher in F crashes (p < 0.04) and pelvis injuries (p < 0.001) higher in L crashes. In FB crashes, however, properly used safety restraints were the primary cause of bowel or colon injuries (p < 0.006). Belts did not prevent thoracic or abdominal solid organ injuries in L crashes. Contact-intrusions (CI) of the car occupant compartment in F crashes were the main cause of brain (A-pillar), lung and liver (steering wheel and instrument panel), and LE (toepan) injuries; but in L crashes, side-door CI caused lung, aorta, liver, and pelvic injuries. In contrast, contact-only (CO) injuries of the steering assembly were mainly responsible for injuries to the lung, heart, and liver in F crashes, and side-door CO for lung, liver, and spleen injuries in L crashes. Deaths and complications after injury were higher among F MVC occupants, or when delta V was > or = 30 mph. Hospital and professional costs reflect the complex care needed for victims of multiple injuries: FB,
