Quality of life after hemicraniectomy for traumatic brain injury in adults. A review of the literature.

Decompressive hemicraniectomy is well accepted for the surgical treatment of intractable intracranial hypertension in cases in which medical management fails. Although it is performed as a life-saving procedure when death is imminent from intracranial hypertension, little is known about the functional outcomes for these patients on long-term follow-up. In this study, the authors performed a systematic review of the literature to examine neurological outcome after hemicraniectomy. A literature search revealed 29 studies that reported outcomes using GOS scores. The GOS scores were transformed to utility values for quality of life using a conversion method based on decision analysis modeling. Based on the literature, 1422 cases were analyzed. The average 6-month-postoperative mortality rate was 28.2%. The mean QOL value among survivors was 0.592, which corresponds roughly to a GOS score of 4. Although more studies are needed for validation of long-term neurological outcome after hemicraniectomy, the assumption that most patients remain in a vegetative state after this intervention is clearly incorrect.

Persistent iliac crest donor site pain: independent outcome assessment.

OBJECTIVE: This study objectively defines the incidence of donor site pain in an independent outcome analysis. In addition, this study identifies the significant discrepancies that are observed when independent outcome assessment results are compared with the incidences determined by review of the operating surgeon's documented findings. METHODS: A review of patients who underwent iliac bone graft harvesting by a single neurosurgeon was conducted. The presence of iliac crest donor site pain, at a time remote from surgery, as determined by specific questioning and recorded in the neurosurgeon's written evaluation was compared with independent assessment findings obtained in structured telephone questionnaire interviews. During a 4-year period, 105 patients met the inclusion criteria. Both the operating surgeon' and independent interviewer's follow-up evaluations were completed for all study patients. Pain was classified into three categories, i.e., no pain, acceptable pain, or unacceptable pain. Patients were also asked to assess the severity of their donor site pain by using a visual analog scale. Statistical analyses comparing the incidences of iliac crest donor site pain in the operating surgeon's evaluations and the independent assessments were performed. RESULTS: When evaluated at a time remote from surgery, the true incidence of iliac crest donor site pain after graft harvest procedures (34%) was significantly greater than previously appreciated by the neurosurgeon (8%). Although occasional or mild pain was observed for 31% of patients, only 3% of all patients experienced unacceptable pain. CONCLUSION: Independent outcome assessment values should be provided to patients in preoperative discussions regarding donor site morbidity. Objective outcome analysis, based on independent observations, is crucial for the most accurate interpretation of perceptions of iliac crest donor site pain.
