Successful outcomes following neurorehabilitation in military traumatic brain injury patients in the United Kingdom

BACKGROUND

The Defence Medical Rehabilitation Centre Headley Court is the UK military rehabilitation unit. A pilot study identified the Mayo-Portland Adaptability Inventory-4 (MPAI-4) as the most appropriate rehabilitation outcome measure in young military patients with acquired brain injury.

METHODS

MPAI-4 scores were prospectively recorded for patients on admission and discharge. At 4 months, independent living and employment status were recorded. Inclusion criteria were all new admissions with traumatic brain injury (TBI). Before injury, all patients were fully employed and lived independently.

RESULTS

In a 3-year period from April 2011, there were 91 TBI patients with complete admission-discharge episodes: by US Department of Defense criteria, 21 were mild, 35 were moderate, and 35 were severe. There was a significant positive relationship between TBI severity and MPAI-4 score on admission (χ = 12.77, df = 2, p = 0.0017).Median age was 27 years, and median duration of admission was 63 days. Employment and independent living status were available for 79 patients at 4 months. Seventy-three patients (92%) were in community-based employment, with 64 (81%) employed in a competitive or transitional work; 6 (8%) were unemployed or in sheltered work. Sixty-nine (87%) were living independently, and 10 (13%) were living with support in their own home, with no one requiring institutional care.Complete MPAI-4 scores were available for 79 patients. There were statistically and clinically significant improvements in MPAI-4 scores between admission and discharge for the overall group: median admission T score was 40.0 (95% confidence interval, 36.0-42.0) and on discharge was 31.0 (95% confidence interval, 27.0-36.0), a nine-point change (Z = 6.53, p < 0.0001). These improvements with rehabilitation were sustained when patients were subdivided by TBI severity or MPAI-4 limitations.

CONCLUSION

This study demonstrates significant functional improvements in military TBI patients following intensive inpatient multidisciplinary rehabilitation, which includes substantial vocational rehabilitation. At 4 months, 92% were employed, and 87% were living independently.

LEVEL OF EVIDENCE

Therapeutic study, level V; prognostic/epidemiologic study, level IV.

The outcome of British combat amputees in relation to military service

BACKGROUND

The study aim was to determine the outcome, in relation to military service in UK military combat amputees.

PATIENTS AND METHODS

Casualties were assessed at mean 2.4 years after injury and graded by a Functional Activity Assessment (FAA) ranging from 1 (fully fit) to 5 (unfit all duties) to score vocational functional outcome. ISS were calculated and the patients were categorised as having unilateral or multiple amputations. The Short Form-36 Health Survey (SF-36) was completed.

RESULTS

Of the 52, 8 patients had left the forces by medical discharge, with 44 continuing to serve. 33 of the 44 had returned to work. 50 patients had FAA grades and were at least 7.6 months post-injury. No patients were graded as FAA1, 8 as FAA2, 18 as FAA3, 19 as FAA4 and 5 as FAA5. There was a trend for the FAA score to increase with injury severity, as measured by ISS i.e. vocational functional outcome was worse with more severe injuries, although this did not reach statistical significance (p=0.095). Multiple amputee patients had significantly higher FAA grades (p<0.001) and were all FAA 4 or 5. Of the 33 patients who had returned to work, 8 were FAA2, 12 FAA3 and 12 FAA4. The mean SF-36 scores for Physical Component Summary (PCS) increased significantly from 36.4 to 43.4 (p=0.001) with rehabilitation, while Mental Component Summary (MCS) was 53.0 and remained similar at 53.6 (p=0.987). MCS scores were similar in these patients to the normal population, 50 (SD 10).

CONCLUSIONS

This study is the first to report the outcomes, with regards to return to work, of the UK military amputees injured in Afghanistan and Iraq Soldiers are surviving more severe and complex injuries than before and the majority are able to return successfully to military work. SF-36 PCS scores improve significantly with rehabilitation, and while MCS scores remain constant, the initial assessments are comparable with a normal population.

End-to-end military pain management

The last three years have seen significant changes in the Defence Medical Services approach to trauma pain management. This article seeks to outline these changes that have occurred at every level of the casualty's journey along the chain of evacuation, from the point of injury to rehabilitation and either continued employment in the Services or to medical discharge. Particular attention is paid to the evidence for the interventions used for both acute pain and chronic pain management. Also highlighted are possible differences in pain management techniques between civilian and military casualties.
