Objective:

Assessment of clinical, functional and psychological outcome after 6 months of moderate and severe TBI

Participants and Methods:

Sixty consecutive participants aged 18 and above with moderate to severe TBI (GCS score of 3-12 at admission) attending the Outpatient Department of Neurosurgery Specialty, Post Graduate Institute of Medical Education and Research, Chandigarh, India were recruited. The exclusion criteria were any pre-existing major psychiatric disorders, intellectual disability, current or past history of substance abuse, degenerative and/or progressive condition, terminal illness and past history of TBI. Ethical clearance was obtained from Institute Ethics Committee. Written informed consent was obtained from all participants prior to inclusion in the study. Socio-demographic details (age, sex, marital status, family type, place of residence, education and occupation) and clinical details (mode of injury, injury severity, treatment, status on discharge, any previous co morbidities) were obtained from participant and hospital records. Functional outcome was assessed by Glasgow Outcome Scale and Barthel’s Index of Activities of Daily Living. Mini Mental State Examination (MMSE) was used to assess cognitive status. Hospital Anxiety and Depression Scale was used to assess symptoms of anxiety and depression.

Results:

Out of 60 patients, 40 had moderate head injury and 20 patients had suffered from severe head injury. There were 53 male (88.3%) and 7 (11.7%) female and the mean age was 34 years (SD=14.5). The mean duration of TBI was 11 months (SD=6.5). Fifty percent participants were married and majority was living in joint/extended families. Majorities were residing in rural localities 36 (60%). With regard to education level 11.7% were illiterate, 33% were educated up to 10th standard and 21.7% up to 12th standard. With regard to occupation, 11.7% were unemployed, 6.7% were housewives, 11.7% were students, 8.3% were retired and rest (61.6%) was engaged in varied occupations.

The most common mode of injury was road traffic accident (90%). Contusion was the most common CT abnormality noted (37 patients, 61.7%). Regarding treatment, 36 patients (60%) underwent surgical intervention and 24 (40%) were managed conservatively. With regard to surgical intervention, 28 (77.8 %) patients underwent decompressive hemicraniectomy and subsequent cranioplasty and rest 8 (22.2 %) underwent craniotomy and hematoma evacuation. As per Glasgow Outcome Scale, 50 (83%) had low disability and 10 (17%) had moderate to severe disability. The mean Barthel’s Index score was 19.6+1.07 (Range 15-20) which indicated that most of the patients had resumed independence in activities of daily living. Only 25% participants were observed to have cognitive impairment (MMSE). With regard to anxiety and depression 16.7% showed symptoms of anxiety whereas 30% showed symptoms of depression (HADS score >8).

Conclusions:

After 6 months of TBI, most participants had resumed independence in activities of daily living but cognitive impairment is persistent in 25% and symptoms of depression in 30% participants.
