Evaluating optimal patient-turning procedures for reducing hospital-acquired pressure ulcers (LS-HAPU): study protocol for a randomized controlled trial.

ABSTRACT: Pressure ulcers are insidious complications that affect approximately 2.5 million patients and account for approximately US$11 billion in annual health care spending each year. To date we are unaware of any study that has used a wearable patient sensor to quantify patient movement and positioning in an effort to assess whether adherence to optimal patient turning results in a reduction in pressure ulcer occurrence.This study is a single-site, open-label, two-arm, randomized controlled trial that will enroll 1812 patients from two intensive care units. All subjects will be randomly assigned, with the aid of a computer-generated schedule, to either a standard care group (control) or an optimal pressure ulcer-preventative care group (treatment). Optimal pressure ulcer prevention is defined as regular turning every 2 h with at least 15 min of tissue decompression. All subjects will receive a wearable patient sensor (Leaf Healthcare, Inc., Pleasanton, CA, USA) that will detect patient movement and positioning. This information is relayed through a proprietary mesh network to a central server for display on a user-interface to assist with nursing care. This information is used to guide preventative care practices for those within the treatment group. Patients will be monitored throughout their admission in the intensive care unit.We plan to conduct a randomized control trial, which to our knowledge is the first of its kind to use a wearable patient sensor to quantify and establish optimal preventative care practices, in an attempt to determine whether this is effective in reducing hospital-acquired pressure ulcers.ClinicalTrials.gov, NCT02533726 .

Project description:INTRODUCTION:Pressure ulcers (PUs) nowadays are a major health problem in society, associated with increased morbidity and increased health care costs. The incidence of HAPU is an indicator of health care quality. OBJECTIVE:To describe the profile of patients with minimal risk on the Norton-MI scale who developed PUs during hospitalization, and to identify the incidence of hospital-acquired pressure ulcers (HAPU). METHODS:Retrospective cohort study conducted between 2014 and 2017. STUDY POPULATION:Patients over 18 years of age classified as "minimum risk" according to Norton-MI, admitted to acute hospital units of the Severo Ochoa University Hospital-Madrid-Spain. Patients were classified as patients with hospital-acquired pressure ulcers (PWHAPU) if they developed one or more new PU during their hospitalization. VARIABLES:Sociodemographic variables, hospitalization units, Morton-MI score and characteristics of the risk factors of HAPU were studied. RESULTS:The risk of PU was evaluated in 5530 patients, being 1260 patients classified as "minimum risk", with a median of 16 points in the Norton-MI scale. The average age was 76 years old and 52.5% were women. Principal causes of admission: traumatological pathologies (20.8%) and cardiovascular pathologies (20%). 129 HAPU were diagnosed in 112 patients, implying an incidence of HAPU of 8.89% (CI95%: 7.44-10.59). 106 PWHAPU (94.6%) presented up to 6 risk factors. The excess pressure and altered skin sensibility were identified as statistically significant risk factors as predictive factors of HAPU. In terms of severity, 55% of the HAPU were category I and 42.6% were category II, mainly with anatomical sacro-coxygeal location. In 65.2% of the patients the HAPU appeared in the first week of hospitalization. CONCLUSION:In our study the incidence of HAPU in patients classified as minimum risk with Norton-MI scale was 8.89%. This elevated risk suggests for future investigations to develop new validity studies of the Norton-MI scale and to maintain a continuo training of professionals in the knowledge of PU risk assessment scales for their safe application in the patients, since it directs the practice of care in the prevention of PUs. It would be advisable to specially control the risk of PUs in care units, mainly in the first week of their hospital stay to minimize the HAPU incidence.

Project description:ObjectivePressure ulcer development is a quality of care indicator, as pressure ulcers are potentially preventable. Yet pressure ulcer is a leading cause of morbidity, discomfort and additional healthcare costs for inpatients. Methods are lacking for accurate surveillance of pressure ulcer in hospitals to track occurrences and evaluate care improvement strategies. The main study aim was to validate hospital discharge abstract database (DAD) in recording pressure ulcers against nursing consult reports, and to calculate prevalence of pressure ulcers in Alberta, Canada in DAD. We hypothesised that a more inclusive case definition for pressure ulcers would enhance validity of cases identified in administrative data for research and quality improvement purposes.SettingA cohort of patients with pressure ulcers were identified from enterostomal (ET) nursing consult documents at a large university hospital in 2011.ParticipantsThere were 1217 patients with pressure ulcers in ET nursing documentation that were linked to a corresponding record in DAD to validate DAD for correct and accurate identification of pressure ulcer occurrence, using two case definitions for pressure ulcer.ResultsUsing pressure ulcer definition 1 (7 codes), prevalence was 1.4%, and using definition 2 (29 codes), prevalence was 4.2% after adjusting for misclassifications. The results were lower than expected. Definition 1 sensitivity was 27.7% and specificity was 98.8%, while definition 2 sensitivity was 32.8% and specificity was 95.9%. Pressure ulcer in both DAD and ET consultation increased with age, number of comorbidities and length of stay.ConclusionDAD underestimate pressure ulcer prevalence. Since various codes are used to record pressure ulcers in DAD, the case definition with more codes captures more pressure ulcer cases, and may be useful for monitoring facility trends. However, low sensitivity suggests that this data source may not be accurate for determining overall prevalence, and should be cautiously compared with other prevalence studies.
