RESUMEN
PURPOSE: We compared pressure ulcer (PU) prevalence patients with a body mass index (BMI) of 40 or more, and Braden Scale scores of 16 or more to patients with lower BMI. METHODS: A cross-sectional study by using existing data was conducted combining patient skin status with BMI. Subjects underwent skin assessment for evidence of skin breakdown by nurses trained in PU assessment. Data from this assessment were combined with historic data gathered from review of medical records and BMI. SUBJECTS AND SETTING: The study was carried out in a tertiary medical center in Eastern North Carolina. Three hundred sixty-two patients were included in the prevalence study. RESULTS: Fourteen percent of all patients had at least 1 PU. The prevalence among patients with a BMI of less than 40 was 12.5% as compared to 26% in patients with a BMI of more than 40 (P 5 .01). When controlling for the effects of BMI, patients with a Braden Scale score of 16 or less were almost 6 times more likely to have a PU as compared to those with Braden Scale scores of more than 16 (P, .001). Body mass index had an independent association with the probability of PU occurrence. Patients with BMIs of more than 40 were almost 3 times more likely to have a PU compared to those with BMIs of 40 or less, after controlling for Braden risk (P 5 .01). CONCLUSION: A BMI of more than 40 and Braden Scale score of 16 or less were found to have an independent and statistically significant association with PU occurrence. Future studies should investigate the predictive validity of BMI along with individual Braden subscales.

BACKGROUND: Mobilization of morbidly obese patients poses significant physical challenges to healthcare providers. The purpose of this study was to examine the staff injuries associated with the patient handling of the obese, to describe a process for identifying injuries associated with their mobilization, and to report on the need for safer bariatric patient handling. METHODS: We performed our study at a 761-bed, level 1 trauma center affiliated with a U.S. medical school. The hospital's Occupational Safety and Health Administration (OSHA) 300 log was expanded to the "E-OSHA 300 log" to specifically identify injuries the staff attributed to bariatric patient handling. The 2007 E-OSHA 300 log was analyzed to identify and describe the frequency, severity, and nature of bariatric versus nonbariatric patient handling injuries. RESULTS: The analyses revealed that during 2007, although patients with a body mass index of > or =35 kg/m(2) constituted <10% of our patient population, 29.8% of staff injuries related to patient handling were linked to working with a bariatric patient. Bariatric patient handling accounted for 27.9% of all lost workdays and 37.2% of all restricted workdays associated with patient handling. Registered nurses and nursing assistants accounted for 80% of the injuries related to bariatric patient handling. Turning and repositioning the patient in bed accounted for 31% of the injuries incurred. The E-OSHA 300 log narratives revealed that staff injuries associated with obese and nonobese patient handling were usually performed using biomechanics and not equipment. CONCLUSION: Manual mobilization of morbidly obese patients increases the risk of caregiver injury. A tracking indicator on the OSHA 300 logs for staff injury linked to a bariatric patient would provide the ability to compare obese and nonobese patient handling injuries. The E-OSHA 300 log provides a method to identify the frequency, severity, and nature of caregiver injury during mobilization of the obese. Understanding the heightened risk of injury associated with manual bariatric patient handling should help healthcare institutions identify deficiencies in their current injury prevention program and focus resources more precisely for safer, systems-based bariatric patient-handling solutions. Effective patient handling systems should also reduce the aura of fear that might be present in some caregivers when mobilizing a bariatric patient.
