Medical device-related pressure injury knowledge assessment for nurses: development and psychometric validation of a multiple choice test.

OBJECTIVE: This study aimed to develop a valid and reliable test to measure nurses' knowledge of medical device-related pressure injuries (MDRPIs). METHODS: The data were collected between May and July 2022. An extensive literature review was performed to develop the instrument. Face and content validity were evaluated in a three-round e-Delphi procedure by an expert panel of 12, including: two wound care nurses; two medical professors; two academic professors/associate professors of nursing with at least 10 years of experience in pressure injuries (PIs) and their care in Turkey; two international professors/associate professors of nursing who have been involved in the National Pressure Injury Advisory Panel and other wound care organisations; and nurses from each of four different fields. RESULTS: A sample of 155 nurses and 108 nursing students participated to enable evaluation of the validity of the multiple-choice test items (item difficulty, discriminating index), and to construct validity, internal consistency and stability of the instrument. A 16-item test reflecting six themes was developed to assess MDRPI knowledge (MDRPI-KAT). The item difficulty index of the questions ranged from 0.36-0.84, while values for item discrimination ranged from 0.31-0.68. The one-week test-retest intraclass correlation coefficient (stability) was 0.82. The overall internal consistency reliability was 0.77. Group scores of nurses with a (theoretically expected) high level of expertise were found to be statistically significantly higher than those of participants with (theoretically expected) less expertise (p<0.05). CONCLUSIONS: The MDRPI-KAT showed acceptable psychometric properties, and can be used in research and practice to evaluate nurses' knowledge of MDRPIs.

Reliability and validity of the Turkish version of pressure ulcer knowledge assessment tool-updated version (PUKAT 2.0).

OBJECTIVE: This study aimed to determine the reliability and validity of the Turkish version of the measurement tool developed and updated by Manderlier et al. to evaluate the nurses' evidence-based knowledge about pressure ulcers. MATERIALS AND METHODS: A methodological study design was used. The instrument was translated to Turkish and back-translated to English. A group of faculty members, including physicians and nurses who are experts in the subject area, evaluated the content validity of the tool with the Lawshe technique. A group of 240 nurses who met the inclusion criteria were reached, and then a pilot study was conducted with 35 nurses by using the test-retest method to determine the invariance of the tool over time. The nurses in the pilot study were excluded from the overall sample, and the evaluations were performed with 205 nurses. Item difficulty index and discrimination index were used for the validity of the items since they were multiple-choice items; Kuder-Richardson 20 analysis was used to determine the internal consistency. RESULTS: The translated and modified instrument demonstrated acceptable psychometric properties as follows: 1) overall content validity index was 0.90, 2) overall test-retest reliability was 0.83 (0.70-0.92 for the sub-themes), 3) item difficulty indexes were 35-75%, 4) discrimination indexes were 0.44-0.92, and 5) overall Cronbach's alfa for the internal consistency was 0.72. CONCLUSIONS: Similar to the earlier version, the Turkish version of PUKAT 2.0 was demonstrated to be a valid and reliable tool to evaluate the nurses' knowledge of evidence-based current information about pressure ulcers.

Outcome of carbapenem or colistin resistant Klebsiella pneumoniae bacteremia in the intensive care unit.

Carbapenem-resistant Klebsiella pneumoniae (CRKp) infections continue to be an important cause of mortality. In this retrospective study, the effect of carbapenem or colistin resistance on mortality in Klebsiella pneumoniae bacteremia and combined meropenem + colistin administration in CRKp bacteremia was evaluated. In addition to that, a mathematical model is applied to explore the relationships between the resistance and mortality. A total of 139 adult patients diagnosed with K. pneumoniae bacteremia(73 carbapenem sensitive and 66 carbapenem resistant) between 01/01/2000 and 31/07/2019 were included in the study. The 30-day mortality in entire cohort were 19.4%. 30-day mortality was significantly higher in the carbapenem resistant-colistin sensitive group and in the carbapenem resistant-colistin resistant group compared to the carbapenem susceptible group. Meropenem + colistin combination was administered to 37 (95%) of carbapenem resistant-colistin sensitive (n = 39) and 25 (93%) of carbapenem resistant-colistin resistant patients(n = 27). Notably, mortality was not significantly affected regardless of whether CRKp was colistin sensitive and whether a high dose and prolonged infusion of meropenem was administered. Mortality is higher in carbapenem resistant Klebsiella pneumoniae bacteremia compared to carbapenem susceptible group. In cases of combined meropenem and colistin administration, high dose and prolonged infusion of meropenem is not superior to standard dose and infusion in both carbapenem resistant-colistin sensitive and carbapenem resistant-colistin resistant K. pneumoniae bacteremia.

Has the COVID-19 Pandemic Affected Brain Death Notifications and Organ Donation Time?

OBJECTIVES: The outbreak of coronavirus disease 2019, known as COVID-19, has rapidly evolved to a global pandemic. This pandemic represents an unprecedented public health issue not only for the general population but also for patients on the transplant wait list. Multiple organizations around the world have published recommendations for the proper conduct of transplant procedures, including donor and recipient screening and perioperative management. We investigated the efficacy of these new recommendations and the effects of SARS-CoV-2 infection on the deceased donation rate, donor organ management, and the time from family consent to procurement. MATERIALS AND METHODS: The characteristics of potential donors diagnosed with brain death between July 15, 2019, and November 18, 2020, were evaluated retrospectively.Demographic and clinical features,the time elapsed from the clinical diagnosis until confirmation, and rates of acceptance were recorded. Potential donors diagnosed with brain death before the pandemic and during the pandemic were compared according to these variables. RESULTS: Within the study period, 40 patients were diagnosed with brain death: 13 before the pandemic and 27 during the pandemic. The organs from 2 donors were procured before the pandemic. Organs from 3 of 8 donors were procured during the pandemic (the organs from 5 of these 8 patients were not donated). The organ donation time was 8.5 ± 2.12 hours (minimum-maximum, 7-10 hours) in the period before the pandemic and 54 ± 11.53 hours (minimummaximum, 45-67 hours) during the pandemic. CONCLUSIONS: The number of donors decreased significantly in our hospital during the pandemic and was similarto the overallrate inTurkey.The duration of the donation process has been prolonged, and strategies to improve rates of organ donation, including infection control, have become a focus of concern.

Sepsis episodes caused by pressure injuries in critical illness: a retrospective observational cohort study.

BACKGROUND: Critically-ill patients (CIPs) with pressure injuries (PIs) may develop bloodstream infections (BSIs). PURPOSE: To identify predisposing factors and discuss diagnosis and management of sepsis-related PIs in CIPs. METHODS: The records of CIPs in the intensive care unit (ICU) between January 1, 2014, and January 1, 2020, with PI with sepsis-diagnoses and with different site cultures that were positive concurrent with bloodstream-cultures were retrospectively reviewed. RESULTS: Ninety-one sepsis episodes were included in the study. Low albumin level (U = 382.00, P = .006), renal failure (odds ratio [OR], 0.108 [95% CI, 0.015-0.783]; P = .025), and length of ICU stay (U = 130.00, P < .001) were identified as risk factors of BSIs due to PIs. The probability of BSI during a sepsis episode was lower in CIPs with PIs with higher C-reactive protein levels (U = 233.00, P < .001) and whose injury resulted from trauma or surgery (OR, 0.101 [95% CI, 0.016-0.626]; P = .014). The mortality was higher in CIPs with PI-induced BSIs (OR, 0.051 [95% CI, 0.008-0.309]; P = .001). CONCLUSIONS: Pressure injury-induced sepsis was associated with a high risk of 28-day mortality. The findings suggest that CIPs with PI are at increased risk of BSIs if they have low albumin levels, renal-failure, and prolonged ICU stay during sepsis episodes.

Evaluation of the combination treatments with intravenous fosfomycin for carbapenem-resistant Klebsiella pneumoniae.

OBJECTIVE: The aim of this study was to evaluate the combination treatments with intravenous fosfomycin for carbapenem-resistant Klebsiella pneumoniae infections in a tertiary-care center. METHODS: Between December 24, 2018 and November 21, 2022, adult patients diagnosed with bloodstream infection or ventilator-associated pneumonia due to culture-confirmed carbapenem-resistant Klebsiella pneumoniae in the anesthesiology and reanimation intensive care units were investigated retrospectively. RESULTS: There were a total of 62 patients fulfilling the study inclusion criteria. No significant difference was recorded in 14- and 30-day mortality among different types of combination regimens such as fosfomycin plus one or two antibiotic combinations. Hypokalemia (OR:5.651, 95%CI 1.019-31.330, p=0.048) was found to be a significant risk factor for 14-day mortality, whereas SOFA score at the time of diagnosis (OR:1.497, 95%CI 1.103-2.032, p=0.010) and CVVHF treatment (OR:6.409, 95%CI 1.395-29.433, p=0.017) were associated with 30-day mortality in multivariate analysis. CONCLUSION: In our study, high mortality rates were found in patients with bloodstream infection or ventilator-associated pneumonia due to carbapenem-resistant Klebsiella pneumoniae, and no significant difference was recorded in 14- and 30-day mortality among different types of combination regimens such as fosfomycin plus one or two antibiotic combinations.

Reliability of CT angiography scoring systems used for brain death and the effect of cranial interventions on the results.

OBJECTIVE: To assess vascular opacifications, the efficiency, and interobserver agreement (IOA) of five different computed tomography angiography (CTA) brain death (BD) scoring systems in patients with and without cranial interventions, for determining alternative findings correctly supporting BD diagnosis by CTA even in cranial intervention presence. METHODS: 45 patients clinically identified with BD and evaluated with CTA were included. IOA of five different scoring systems used for CTA BD diagnosis, the effect of intracranial interventions on scoring systems, and vascular opacification were evaluated. RESULTS: IOA was almost perfect (κ = 0.843-0.911, p < 0.05) and substantial (κ = 0.771-0.776, p < 0.05) in all scoring systems. Significant relationships were observed between craniectomy presence and middle cerebral artery M4 segment and internal cerebral vein (ICV) opacification. No opacification was observed in straight sinus (SS) by observers in any of the craniectomized patients. CONCLUSION: IOA of CTA scoring systems is adequate. But a significant degree of false-negative results is observed due to ICV filling in craniectomy cases. Opacification presence in SS can give an idea of BD in these cases.

Prevalence of pressure ulcers in hospitalized adult patients in Bursa, Turkey: A multicentre, point prevalence study.

RATIONALE, AIMS, AND OBJECTIVES: Pressure ulcers (PUs), which are preventable complications, increase the cost of health care and the risk of prolonged hospital stay, as well as morbidity and mortality. In this study, we aimed to describe the prevalence, clinical features, and risk factors for PUs among hospitalized patients. METHOD: This study was cross-sectional and conducted over a single day in all the care units. Data were recorded on a patient observation form that included demographic data, diagnosis of admission to the hospital or intensive care unit (ICU), comorbidity and chronic diseases, location, stage of PU, and Braden Scale score. Acute physiology and chronic health evaluation (APACHE) II score, Glasgow coma score (GCS), PaO2 /FiO2 ratio, and albumin level were recorded for ICU patients. RESULTS: A total of 1548 adult patients participated in the study. Of these patients, 177 (11.43%) had PU. The patients with PU had more advanced age, lower body mass index (BMI), and longer duration of hospital and ICU stay (for all P = .001). Evaluation of PU in the first 24 hours after hospital admission and the last PU evaluation time also showed a significant effect (both P = .001). Braden Scale score less than or equal to 13 in the first evaluation after hospital admission increased the risk of PU. Albumin was 2.78 ± 0.57 gm/dL in ICU patients, and albumin level was significantly lower in patients with PU (P = .001). PUs were located mainly in the sacrum (47.59%) and were classified as stage II (42.76%) for all patients. CONCLUSIONS: The prevalence of PU is related to the age and severity of patient clinical status, as predicted by the Braden Scale score and APACHE II score, and length of hospital and ICU stay. Low albumin level is also related to development of PUs in ICU patients.

[The use of the laryngeal mask airway and the cuffed oropharyngeal airway during percutaneous tracheostomy]. / Perkütan trakeostomi sirasinda "Larengeal Maske" ve "Kafli Orofarengeal Havayolu" kullanimi.

BACKGROUND: The aim of our study is to compare the safety and efficiency of the use of the laryngeal mask airway (LMA) and the cuffed oropharyngeal airway (COPA) with the use of endotracheal tube (ETT) for maintain patent airway during percutaneous tracheostomy (PCT). METHODS: The patients were randomly assigned to LMA group (n=35, M/F; 28/7, age; 52 [18-79]), COPA group (n=31, M/F; 23/8, age; 57 [18-80]) and ETT group (n=30, M/F; 22/8, age; 49 [18-80]) with respect to use of LMA, COPA and ETT in order to maintain patent airway during PCT procedure. PT was performed as described by Griggs et al. Complications occurred during and after PCT procedure and airway manipulations required to maintain a patent airway were recorded. RESULTS: Duration of PT was longer in the ETT group comparing with the other groups (for both groups; p<0.01). The LMA failed to maintain patent airway in 1 of 35 patients (2.9%) and the COPA failed to maintain patent airway in 3 of 31 patients (9.7%). The airway intervention required to maintain patent airway was found to be higher in the COPA group (45.2%) than in the LMA group (11.4%) (p<0.01). There was no significant difference with respect to the complications between the groups. CONCLUSION: In our study, LMA and COPA were inserted easily during PCT with high success rates, but airway manipulations were higher in the COPA group. In our opinion, supra/infraglottic airway devices to maintain patent airway during PCT should be chosen according to patient's status and physician's experience.

Guillain-Barré Syndrome and Human Immunodeficiency Virus.

Guillain-Barré syndrome (GBS) is an acute disease characterised by symmetrical muscle weakness, loss of sensation and reflex. There is usually a viral infection at the beginning of the disease. Here, we report a GBS case which did not respond to any treatment strategy at first and was diagnosed as Human Immunodeficiency Virus positive (HIV+) during the search for the aetiology. A 32-year-old male patient who presented to a medical centre with symptoms of gait disturbance and arm and leg numbness was found to have albuminocytologic dissociation upon cerebrospinal fluid examination. After the diagnosis of GBS, immunoglobulin G (IVIG) therapy (400 mg kg(-1) day(-1) 5 days) was started as a standard therapy. This therapy was repeated due to a lack of improvement of symptoms. During this therapy, the patient was sent to our clinic with symptoms of respiratory failure and tetraplegia. He was conscious, cooperative, haemodynamically stable and his arterial blood gas analyses were: pH: 7.28, PaO2: 74.4 mmHg, PCO2: 63.8 mmHg. He was intubated, mechanically ventilated and underwent plasmapheresis. After the investigation of aetiology, HIV(+), CD4/CD8: 0.17, absolute CD4: 71 cells mL(-1) were detected and antiretroviral therapy was started. The patient died from multiple organ failure due to sepsis on day 35. In conclusion, HIV infection should be kept in mind in GBS patients, especially those not responding to routine treatment. As a result, not only could the patient receive early and adequate treatment, but also HIV infection transmission would be avoided.
