An exploratory study of pressure ulcers after spinal cord injury: relationship to protective behaviors and risk factors.

OBJECTIVES: To identify protective behaviors and risk factors associated with the development of pressure ulcers (PUs) after spinal cord injury (SCI). DESIGN: A cross-sectional study to evaluate the relationship between protective behaviors and risk factors and 3 PU outcomes: a current PU, PUs within the past year, and ever hospitalized for a PU. Logistic regression was then used to identify the variables most strongly associated with PU outcomes. SETTING: Data were collected by case managers employed by the Arkansas Spinal Cord Commission, an agency that provides services to persons with SCI. PARTICIPANTS: A total of 650 of 991 eligible individuals with SCI from a statewide population-based SCI registry participated. All ambulatory participants were eliminated, leaving 560 patients. Average age of the respondents was 27.2 years at injury (median age, 25yr) and 43.6 years at the time of the survey (median age, 42yr). MAIN OUTCOME MEASURES: A 200-item interview was developed to measure a broad range of outcomes associated with SCI (including secondary conditions such as PUs), as well as risk and protective behaviors related to these outcomes. RESULTS: Several characteristics and behaviors were related to PU outcomes. Being underweight (odds ratio [OR] = 2.18), having used medications to treat pain (OR = 1.33) or spasticity (OR = 1.31), having smoked at least 100 cigarettes over a lifetime (OR = 1.31), and being a current smoker (OR = 1.21) were associated with having a PU in the past year. Having completed a college degree (OR = 0.23), being married (OR = 0.49), and being currently employed (OR = 0.54) were associated with a lower risk of having a PU in the past year. Being underweight (OR = 1.94), having a history of incarceration (OR = 1.78), having attempted suicide (OR = 1.71), and reporting alcohol or drug treatment (OR = 1.65) were associated with having been hospitalized for a PU since injury. This study was unable to evaluate the efficacy of traditional health maintenance or protective behaviors for PUs, such as weight shifts or skin checks. CONCLUSIONS: PUs are least likely to occur among individuals who maintain normal weight, return to a work and family role, and who do not have a history of tobacco use, suicidal behaviors, or self-reported incarcerations, or alcohol or drug abuse. Additional research is needed to identify better the risk factors for the occurrence of PUs.

Endovascular and surgical treatment of unruptured cerebral aneurysms: comparison of risks.

Unruptured cerebral aneurysms are commonly treated by surgical clipping, but endovascular coil embolization is increasingly employed as an alternative. In a blinded review of unruptured aneurysms treated at our institution since 1990, we identified patients whose aneurysms were judged to be treatable by both neurosurgeons and neurointerventional radiologists. A change in Rankin Scale score of 2 or more from hospital admission to discharge, indicating a new moderate disability or worse, was predefined as the primary outcome measure. Long-term follow-up was obtained by mailed questionnaire and telephone interview. Length of stay and hospital charges were totaled for all hospitalizations, including follow-up. Sixty-eight patients treated surgically and 62 patients treated with endovascular coil embolization were considered candidates for either procedure on blinded review, and overall anticipated procedure risk was rated as identical. A larger proportion of patients in the surgical group developed a change in Rankin Scale score of 2 or more (25% of surgical patients vs 8% of endovascular patients). Total length of stay was longer (mean days: 7.7 for surgical patients vs 5.0 for endovascular patients) and hospital charges were greater (mean, $38,000 for surgical patients vs $33,400 for endovascular patients) for the surgical patients. At follow-up, an average of 3.9 years after the procedure, surgical patients were more likely to report persistent new symptoms or disability since treatment (34% of surgical patients vs 8% of endovascular patients) and a longer period for recovery to normal (50% returning to normal in 1 year for surgery and in 27 days for coil embolization). Coil embolization of unruptured cerebral aneurysms seems to be associated with significantly fewer complications than surgical clipping. More long-term data on aneurysm rupture rates are required to confirm efficacy.
