Objective: This study aims to determine the predictive power of the Norton, Braden and Waterlow scales in determining risk of pressure injury (PI) in surgical patients. Method: This prospective study was carried out in the surgery clinic of a training and research hospital in Istanbul, Turkey between January and April 2017. The study sample consisted of adult patients aged ≥18 years and who did not have PI on admission to the clinic, had abdominal surgery under general anaesthesia and who stayed in the clinic for at least 48 hours. The data were collected using the Turkish versions of the Norton, Braden and Waterlow risk assessment scales. The predictive validity of PI risk assessment tools was assessed based on their sensitivity, specificity, positive and negative predictive values and the area under the receiver operating characteristic (ROC) curve. Predictive capacity was measured as relative risk (RR) with 95% confidence intervals (CI). Results: The study sample included 250 patients, and the incidence of PI was 12%. The sensitivity, specificity, positive predictive value and negative predictive value were: 83.3%, 45.4%, 17.2% and 95.2%, respectively, for the Norton scale (a cut-off point of 14); 100%, 40.4%, 18.6% and 100%, respectively, for the Braden scale (a cut-off point of 16); and 100%, 48.1%, 20.8% and 100%, respectively, for the Waterlow scale (a cut-off point of 10). The areas under the ROC curve were 0.749 for the Norton, 0.771 for the Braden and 0.971 for the Waterlow scales. This study's findings produced the following predictive capacity indicators: Norton (RR=3.62; 95%CI=1.43–9.14), Braden (RR=33.88; 95%CI=2.09–547.66); and Waterlow (RR=45.01; 95%CI=2.78–727.97). Conclusion: In this study, the Waterlow scale demonstrated the best values of predictive validity among the three scales in the assessment of PI risk. However, all three scales had low specificity despite high sensitivity in terms of a good risk prediction. No definitive decision could be reached on the predictive capacities of the scales because of wide CIs.
Tympanic thermometers seem to be optimal for use with the elderly population. Owing to the ease of application, safety, and tolerability in the elderly; their use in routine practice seems to be advantageous. Higher reading of tympanic measurements may lead to a suspicion of infection, especially in the elderly, which may be helpful in clinical treatment in this age group.
<p><strong>Background:</strong> Pain, anxiety, and sleep disorders are common side effects of coronary artery bypass graft (CABG) surgery. Although pharmacological agents are currently used in the treatment of these problems, in addition to their undesirable side effects, they increase healthcare costs, and their inadequate control leads to morbidities, prolonged hospital stay and increased burden of care. Therefore, supportive interventions are needed. The aim of this study is to determine the effect of lavender oil inhalation on the pain intensity, anxiety and sleep quality of patients that underwent CABG surgery.</p><p><strong>Methods:</strong> This study was planned as a prospective randomized controlled trial. Participants meeting the inclusion criteria will be randomly assigned to the intervention and control groups. During the hospitalization period after CABG surgery, 2% lavender oil (<em>Lavandula angustifolia</em>) inhalation will be applied to the intervention group three times a day, while the control group will only receive routine care. The pain intensity of the groups will be evaluated with the numeric rating scale, anxiety levels with the state-trait anxiety inventory, and sleep quality with the Richards-Campbell sleep questionnaire.</p><p><strong>Conclusions:</strong> There is a need for new approaches to improve the physiological and psychological health of patients after CABG surgery and help them return to their daily life activities and social lives in a shorter time. This trial will allow for the assessment of the effects of this intervention and provide valuable evidence to guide clinical practice.</p><p><strong>Trial registration:</strong> This trial was registered in May, 2022 (NCT05377983).</p>
