Effect of Hospital Linens on Unit-Acquired Pressure Injuries for Adults in Medical ICUs: A Cluster Randomized Controlled Trial.

ABSTRACT: Researchers have shown in laboratory studies that different types of fabrics were associated with changes in skin moisture, friction, shear, and temperature that may predispose patients to pressure injury. There was an association between type of fiber used in hospital linens and pressure injury development in previous clinical studies. We examined if bed linens made from a newly developed synthetic fiber fabric affected occurrence rate, time to development, and severity of unit-acquired pressure injury in critically ill adult inpatients.

Design

Cluster randomized controlled trial.

Setting

Five adult medical ICUs within one quaternary care center in the Midwest United States.

Patients

Patients were assigned to a unit based on bed availability. In total, there were 3,332 patients in the study.

Interventions

Participating medical ICUs were randomly assigned to cotton fiber or synthetic fiber linens for the first 6 months of the study period, and assignment reversed after a 14-day washout period for the final 6 months.

Measurements and main results

Unit-acquired pressure injury occurrence rate, time to first unit-acquired pressure injury, and severity were evaluated using generalized mixed effect models with patient as a random effect, and a marginal Cox proportional hazards model with repeated admissions from the same patient accounted for by use of a sandwich estimator of the variance. There were 1,706 patients on cotton fiber linens and 1,626 patients on synthetic fiber linens. Groups were similar on demographics except race and admitting diagnosis groupings. Occurrence rate (p = 0.99), time to development (p = 0.99), and maximum severity of unit-acquired pressure (p = 0.86) were similar between groups before and after controlling for race and admitting diagnosis groupings.

Conclusions

Linen type did not affect unit-acquired pressure injury occurrence rate, severity, or timing. Standard unit-acquired pressure injury prevention efforts may be more cost-effective than investment in synthetic fiber linens.

Project description:PurposeThe purpose of this study was to examine clinical characteristics and risk factors for critically ill patients who develop pressure injuries and identify the proportion of validated unavoidable pressure injuries associated with the proposed risk factors for acute skin failure (ASF).DesignRetrospective case-control comparative study.Subjects and settingThe sample comprised adult critically ill participants hospitalized in critical care units such as surgical, trauma, cardiovascular surgical, cardiac, neuro, and medical intensive care and corresponding progressive care units in 5 acute care hospitals within a large Midwestern academic/teaching healthcare system. Participants who developed hospital-acquired pressure injuries (HAPIs) and patients without HAPIs (controls) were included.MethodsA secondary analysis of data from a previous study with HAPIs and matching data for the control sample without HAPIs were obtained from the electronic health record. Descriptive and multivariate logistic regression analyses were conducted.ResultsThe sample comprised 475 participants; 165 experienced a HAPI and acted as cases, whereas the remaining 310 acted as controls. Acute Physiology and Chronic Health Evaluation (APACHE II) mean score (23.8, 8.7%; P < .001), mortality (n = 45, 27.3%; P = .002), history of liver disease (n = 28, 17%; P < .001), and unintentional loss of 10 lb or more in 1 month (n = 20, 12%; P = .002) were higher in the HAPI group. Multivariate logistic regression analysis identified participants with respiratory failure (odds ratio [OR] = 3.00; 95% confidence interval [CI], 1.27-7.08; P = .012), renal failure (OR = 7.48; 95% CI, 3.49-16.01; P < .001), cardiac failure (OR = 4.50; 95% CI, 1.76-11.51; P = .002), severe anemia (OR = 10.89; 95% CI, 3.59-33.00; P < .001), any type of sepsis (OR = 3.15; 95% CI, 1.44-6.90; P = .004), and moisture documentation (OR = 11.89; 95% CI, 5.27-26.81; P <.001) were more likely to develop a HAPI. No differences between unavoidable HAPI, avoidable HAPI, or the control group were identified based on the proposed ASF risk factors.ConclusionThis study provides important information regarding avoidable and unavoidable HAPIs and ASF. Key clinical characteristics and risk factors, such as patient acuity, organ failure, tissue perfusion, sepsis, and history of prior pressure injury, are associated with avoidable and unavoidable HAPI development. In addition, we were unable to support a relationship between unavoidable HAPIs and the proposed risk factors for ASF. Unavoidability of HAPIs rests with the documentation of appropriate interventions and not necessarily with the identification of clinical risk factors.

Project description:BackgroundHospital-acquired disability (HAD) is common and often related to low physical activity while in the hospital.ObjectiveTo examine whether wearable hospital activity trackers can be used to predict HAD.DesignA prospective observational study between January 2016 and March 2017.SettingAn academic medical center.ParticipantsCommunity-dwelling older adults, aged 60?years or older, enrolled within 24?hours of admission to general medicine (n = 46).Main measuresPrimary outcome was HAD, defined as having one or more new activity of daily living deficits, decline of four or greater on the Late-Life Function and Disability Instrument (calculated between baseline and discharge), or discharge to a skilled nursing facility. Hospital activity (mean active time, mean sedentary time, and mean step counts per day) was measured using ankle-mounted accelerometers. The association of the literature-based threshold of 900 steps/day with HAD was also evaluated.ResultsMean age was 73.2?years (SD = 9.5?years), 48% were male, and 76% were white. Median length of stay was 4?days (interquartile range [IQR] =?2.0-6.0?days); 61% (n = 28) reported being able to walk without assistance of another person or walking aid at baseline. Median daily activity time and step counts were 1.1 h/d (IQR = 0.7-1.7 h/d) and 1455.7 steps/day (IQR = 908.5-2643 steps/day), respectively. Those with HAD (41%; n = 19) had lower activity time (0.8 vs 1.4 h/d; P = .04) and fewer step counts (1186 vs 1808 steps/day; P = .04), but no difference in sedentary time, compared to those without HAD. The 900 steps/day threshold had poor sensitivity (40%) and high specificity (85%) for detecting HAD.ConclusionsLow hospital physical activity, as measured by wearable accelerometers, is associated with HAD. Clinicians can utilize wearable technology data to refer patients to physical/occupational therapy services or other mobility interventions, like walking programs. J Am Geriatr Soc 68:261-265, 2020.
