OBJECTIVES:To determine optimal repositioning frequency of nursing home (NH) residents at risk for pressure ulcers (PrUs) when cared for on high-density foam mattresses. DESIGN: Multisite, randomized, clinical trial, known as Turning for Ulcer ReductioN (TURN Study). SETTINGS: NHs in the United States (n = 20) and Canada (n = 7) using high-density foam mattresses. PARTICIPANTS: Consenting residents (N = 942) aged 65 and older without PrUs at moderate (scores 13-14) or high (scores 10-12) risk of PrUs according to the Braden Scale. INTERVENTION: Participants were randomly allocated using risk stratification (moderate vs high) to a repositioning schedule (2, 3, or 4 hour) for 3 weeks. Blinded assessors assessed skin weekly. MEASUREMENTS: PrU incidence (coccyx or sacrum, trochanter, heels). RESULTS: Participants were mostly female (77.6%) and Caucasian (80.5%) and had a mean age of 85.1 AE 7.7. The most common diagnoses were cardiovascular (76.9%) and dementia (72.5%). Nineteen (2.0%) participants developed superficial PrUs. There was no significant difference (Wilcoxon test for ordered categories) in PrU incidence (P = .68) according to repositioning group (2 hour, 8/321, 2.5%; 3 hour, 2/326, 0.6%; 4 hour, 9/ 295, 3.1%), nor was there a statistically significant difference in the incidence of PrU between the high and moderate-risk groups (P = .79). Also, PrU incidence was not statistically significantly different between high-risk participants based on repositioning schedule (6/325, 1.8%, P = .90) or between moderate-risk participants based on repositioning schedule (13/617, 2.1%, P = .68). CONCLUSION: There was no difference in PrU incidence over 3 weeks of observation between those turned at 2-, 3-, or 4-hour intervals in this population of residents using high-density foam mattresses at moderate and high risk of developing PrUs when they were repositioned consistently and skin was monitored. This finding has major implications for use of nursing staff and cost of NH care.

Skin temperature MSE and the spectral exponent were significantly different between low-risk and higher risk residents and residents who did and did not develop pressure ulcers. The study supports measurement of skin temperature regulation as a component of tissue tolerance to pressure.

Assisted living (AL) residences are residential long-term care settings that provide housing, 24-hour oversight, personal care services, health-related services, or a combination of these on an as-needed basis. Most residents require some assistance with activities of daily living and instrumental activities of daily living, such as medication management. A resident plan of care (ie, service agreement) is developed to address the health and psychosocial needs of the resident. The amount and type of care provided, and the individual who provides that care, vary on the basis of state regulations and what services are provided within the facility. Some states require that an RN hold a leadership position to oversee medication management and other aspects of care within the facility. A licensed practical nurse/licensed vocational nurse can supervise the day-to-day direct care within the facility. The majority of direct care in AL settings is provided by direct care workers (DCWs), including certified nursing assistants or unlicensed providers. The scope of practice of a DCW varies by state and the legal structure within that state. In some states, the DCW is exempt from the nurse practice act, and in some states, the DCW may practice within a specific scope such as being a medication aide. In most states, however, the DCW scope of practice is conscribed, in part, by the delegation of responsibilities (such as medication administration) by a supervising RN. The issue of RN delegation has become the subject of ongoing discussion for AL residents, facilities, and regulators and for the nursing profession. The purpose of this article is to review delegation in AL and to provide recommendations for future practice and research in this area.
