    Assessment of the risk of pressure ulcer during the perioperative period: adaptation of the Munro scale to Turkish
    (Elsevier Sci Ltd, 2021) Gul, Asiye; Yavuz, Hafize Özge; Şengül, Tuba; Faculty Member; School of Nursing; 59230
    Aim of the Study: This study was conducted to adapt the Munro Pressure Ulcer Risk Assessment Scale (Munro Scale) to Turkish and to test its validity and reliability. Materials and Methods: In the methodological study, the data were collected using the patient identification form, the Braden Scale, and the Munro Scale. A total of 188 patients were diagnosed for the risk of preoperative and intraoperative pressure ulcer, and then re-evaluated in the recovery room and in their bed. Results: The study group consisted of 81 (43.1%) males and 107 (56.9%) females with a mean age of 51.98 +/- 16.87. The Kaiser-Meyer-Olkin sampling adequacy test was 0.588 and the Bartlett's test was 430.471. The results of goodness of fit indices were not as expected value in the confirmatory factor analysis. In the exploratory factor analysis, it was determined that the factor loadings of the Munro Scale varied between 0.336 and 0.873 and explained 62% of the total variance. In the parallel-form method performed for the reliability of the scale, it was observed that there was a weak and negative correlation between the total scores of the Munro Scale and Braden Scales before the surgery and a negative and moderate correlation between the total scores after the surgery. The total Cronbach's alpha value was found to be 0.504. In the reliability analysis of the scale, interrater correlation coefficients were found to be 0.865-0.998. Conclusions: The Munro Scale can be used to assess the risk of pressure injuries in perioperative patients and may help nurses to identify high-risk patients.

    (Elsevier Sci Ltd, 2022) Gül, Asiye; N/A; Şengül, Tuba; Yılmaz, Dilek; Gökduman, Tuğba; Faculty Member; Other; Other; School of Nursing; N/A; N/A; N/A; Koç University Hospital; Koç University Hospital; 59230; N/A; N/A
    Aim of the Study: This study was conducted to translate the ELPO risk assessment scale for the development of pressure injuries due to surgical positioning to Turkish and to test its validity and reliability in the Turkish Population. Materials and Methods: The data were collected using the patient identification form, the risk assessment scale for the prevention of injuries due to surgical positioning, and the Braden Scale. This scale consisted of a total of seven items, each of which contained five sub-items. It is rated between 1 and 5 in the Likert type. The total score of the scale ranges between 7 and 35. The risk of developing pressure injuries increases in patients as the score increases. Results: A total of 184 patients were included in the study sample. The mean age of the group was 55.96 +/- 17.90, and the content validity index was 0.944. The sensitivity of the test was 60%, the specificity was 66%, and the accuracy was 66%. There was a negative, weak, statistically significant correlation between the total scores of the risk assessment scale for the prevention of injuries due to surgical positioning and the Braden scale. The mean total score of the scale was 18.45 +/- 2.96 (12-26) and 35.9% (n = 66) of the group were at high risk. Conclusions: The ELPO, which includes the risks specific to patients during surgery, can be used as an assessment scale for the development of pressure injury due to surgical positioning for Turkish population.

    Response to a letter to the editor regarding "connectors as a risk factor for blood-associated infections (3-way stopcock and needleless connector): a randomized-experimental study"
    (Mosby-Elsevier, 2020) Guven, Betul; Ocakci; Kaya, Nurten; N/A; Şengül, Tuba; Ocakçı, Ayşe Ferda; Faculty Member; Faculty Member; School of Nursing; School of Nursing; 59230; 1729
    In our study, “Results of this study found no significant difference between rates of colonization in NCs and TWSs,” this sentence was perceived as a contradiction. This contradiction was explained in the letter by Devrim. In our study, as indicated by Devrim, there was a difference in the rate of colonization in needleless connectors (NC) and 3-way stopcock (TWS) attached to peripheral venous catheters, but no statistically significant difference was found in the rate of colonization in central and port catheters. This is stated in the abstract section with the following sentence: “When the results of colonization for patients using TWS and NC were compared, the peripheral venous catheters (using a TWS) resulted in a significantly higher increase in reproduction than patients using NC (P ≤ .01) and no significant difference in the level of colonization in other types of connectors or catheters (P ˃ .05).” The results section is associated with the other data obtained; it has been emphasized that connectors attached to intravenous (IV) catheters are a risk factor for catheter-related bloodstream infections. In addition, it is necessary for a scientific research to reach a general conclusion by discussing the findings with other literature. Indeed, studies comparing the effect of periferal intravenous catheter- integrated NC and TWS on the causing of infection are very limited, and available studies2,3 state that there is no difference between the 2 types of connectors. In addition, the number of injections, duration of use of the device, and microbial contamination rate were not confounders in both studies. In our study, the procedure for obtaining the culture from the connectors was carried out with attention, and this was stated in the study. Standard maintenance of catheters and connectors are summarized in Table 1. This table could not be shown in the study due to the publication standards of the Journal, but the process was summarized. In addition, clinical examinations of the patients were made in terms of signs of infection and body temperature measurements, and laboratory findings (C-reactive protein and blood leukocyte levels) were evaluated.

    Effectiveness of using ultrasonography in peripheral intravenous catheter application
    (Koç University School of Nursing, 2022) Acaroğlu, Rengin; N/A; Şengül, Tuba; Faculty Member; School of Nursing; 59230
    Background: Peripheral intravenous catheter applications, in addition to the traditional method in various clinics, are among the common methods using ultrasound guidance. Methods: The study was conducted using a quasi-experimental design on 30 patients who were treated in a daily chemotherapy unit and agreed to participate in the study. The data of the study were collected using “Patient Information Form,” “State Anxiety Inventory,” “Pain Scale,” “Satisfaction Scale,” “Infiltration Scale,” “Visual Infusion Phlebitis Assessment Scale,” and “Peripheral Intravenous Catheterization Follow-up Form.” Patients were randomly assigned to the application groups, peripheral intravenous catheterization was performed using ultrasonography-guided method and the traditional method, and the application methods were repeated by crossing the groups. The data were analyzed by descriptive analysis, a Chi-square, and paired t-test. Results: The mean age of the participants in the study was 56.16 ± 12.29 and the mean body mass index was 32.71 ± 4.43. of which, 53.3% of the patients were male and 36.7% of the patients had lung cancer. There was no significant difference between ultrasonographyguided method and the traditional method. Peripheral intravenous catheterization applications in terms of success rate (100.0%-93.3%), number of interventions (1 ± 0.0-1.20 ± 0.40), and state anxiety score means (46.93 ± 6.10-45.10 ± 6.60), respectively. In the USG-guided method, while the time spent was 63.33 ± 34.52 second, pain intensity was 1.53 ± 1.13, and satisfaction level was 9.76 ± 0.81, a significant difference was found in terms of the time spent (84.53 ± 47.13 second), pain intensity (2.96 ± 1.77), and satisfaction score average (7.433 ± 1.40) in the traditional method. A statistically significant difference was found between these results obtained in both application methods (P < .05). There were no complications that occurred in the patients of both application methods. Conclusion: It was found that the application of peripheral intravenous catheter in ultrasonography-guided method reduced the time spent for the intervention, reduced the pain felt, and increased the level of satisfaction, however, had no effect in terms of complication development. The study is recommended to be repeated in different clinical area and patient groups.

    Connectors as a risk factor for blood-associated infections (3-way stopcock and needleless connector): a randomized-experimental study
    (Mosby-Elsevier, 2020) Güven, Betül; Kaya, Nurten; Şengül, Tuba; Ocakçı, Ayşe Ferda; Faculty Member; Faculty Member; School of Medicine; 59230; 1729
    Background: Microorganisms causing catheter-related bloodstream infections colonize to intravenous catheters (IVC)-particularly to connectors mounted to catheters. The aim of this study was to examine the colonization in 3-way stopcock (TWS) connectors and needleless connectors (NCs) that integrated into central, port, and peripheral venous catheters. Methods: This random, experimental study consisted of 180 connectors that were inserted into the IVCs of patients in general surgery, reanimation intensive care, and daily chemotherapy units. Cultures of the connectors were obtained at least 48 hours after connecting to IVCs. Results: This study showed that gram-negative, gram-positive, and other pathogens reproduced, although their colonization level was not high enough to develop an infection. When the results of colonization for patients using TWS and NC were compared, the peripheral venous catheters (using a TWS) resulted in a significantly higher increase in reproduction than in patients using NC (P ≤ .01) and no significant difference in the level of colonization in other types of connectors or catheters (P ˃ .05). Conclusions: The study's results indicated no significant difference between NC and TWSs in terms of reproduction. It should also be noted that connectors integrated into IVC pose a risk in the development of catheter-related bloodstream infections.

    Aim: The intravenous connectors are the gatekeeper of the intraluminal fluid pathway and frequently used by nurses in clinical areas. This study aimed to determine nurses’ satisfaction of connectors used in intravenous therapy administration. Methods: This descriptive study was conducted between January and May 2016 in a training and research hospital in Istanbul. The sample of the study comprised 80 nurses/midwives working in the general surgery unit, reanimation intensive care unit, and outpatient chemotherapy unit. The data were collected by the Personal Information Form and Satisfaction Scale. Descriptive statistics,Spearman's rank correlation, independent sample t test and one-way analysis of variance (ANOVA) were used to analyze the data. Results: of the participants, 65% stated they had not received any training in their institutions regarding connector usage, and 61.3% reported receiving no training about catheter-related infections. The participants’ satisfaction score for the use of the connector (according to a 0–10 degree visual analog scale) was 6.45±3.12. It was determined that there was a significant relationship between the connector satisfaction scores and the easy use of the connectors (p<0.01). Conclusion: Control of catheter-related infections is a priority worldwide. Nurse training in the use of connectors and connector satisfaction can contribute to the prevention of infections by improving usage adherence. / Amaç: İntravenöz konnektörler intralüminal sıvı yolunun kapı bekçileridir ve klinik alanlarda hemşireler tarafından sıklıkla kullanılmaktadır.

    Determination of nurses' level of knowledge on the prevention of pressure ulcers: The case of Turkey
    (Elsevier Sci Ltd, 2020) N/A; N/A; N/A; Şengül, Tuba; Karadağ, Ayişe; Faculty Member; Faculty Member; School of Nursing; School of Nursing; 59230; 3549
    Aim of the study: Pressure ulcers (PUs) constitute a health issue that has a high prevalence and incidence rate in acute and long-term care, requiring long-term nursing care for treatment and prevention. Therefore, nurses should have adequate knowledge of the interventions and practices used to prevent PUs. Materials and methods: This study employed a descriptive and cross-sectional design to assess the level of nurses' knowledge concerning preventive interventions for PUs. Based on data found in the literature, researchers developed a 16-question Participant Information Form (including age, gender, level of education, employed ward, and training on PUs) and used this form, along with the Turkish version of the Pressure Ulcer Prevention Knowledge Assessment Instrument (PUPKAI-T), to collect data. Results: A group of 471 nurses working in two foundation hospitals in 2018 participated in the study by completing a questionnaire. Among the participants, 44.2% worked in surgery, 21.2% in internal Medicine; and 34.6% in other wards (such as intensive care, pediatrics, and the operating theater). Most of the nurses(73.5%) held a bachelor's degree, and their average work experience was 7.27 7.00 years. It was determined that 69.4% of the nurses had not received in-service training relating to PUs, 55.6% did not attend lectures/conferences or read articles on the prevention of PUs, and 59.7% rated themselves as "adequate" in interventions used to prevent PUs. Based on the use of PUPKAI-T, 17 individuals (3.6%) scored equal to or more than the 60% cut-off value, and 454 individuals (96.4%) scored less than 60%. The mean level of knowledge on PUs was calculated as 11.1 +/- 2.659 (range: 1-18) out of 26 questions. Conclusions: Results of the study showed that the general level of knowledge of nurses in preventing PUs are extremely insufficient. Therefore, various strategies should be developed to increase nurses' level of knowledge on the etiology and development, classification and observation, and risk assessment of PUs, as well as on nutrition plans and preventive interventions.
