Nosocomial pneumonia in the medical and surgical patient: Risk Factors and Primary Management

Abstract Graphical Abstract OBJECTIVES The aim was to compare the relative effects of red blood cell (RBC) transfusion and preoperative anaemia on 5-year mortality following open-heart cardiac surgery using structural equation modelling. We hypothesized that patient risk factors associated with RBC transfusion are of larger importance than transfusion itself. METHODS This prospective cohort study, part of the Cardiac Surgery Outcome Study at St. Olavs University Hospital, Trondheim, Norway, included open-heart on-pump cardiac surgery patients operated on from 2000 through 2017 (n = 9315). Structural equation modelling, which allows for intervariable correlations, was used to analyse pathway diagrams between known risk factors and observed mortality between 30 days and 5 years postoperatively. Observation times between 30 days and 1 year, and 1–5 years postoperatively were also compared with the main analysis. RESULTS In a simplified model, preoperative anaemia had a larger effect on 5-year mortality than RBC transfusion (standardized coefficients: 0.17 vs 0.09). The complete model including multiple risk factors showed that patient risk factors such as age (0.15), anaemia (0.10), pulmonary disease (0.11) and higher creatinine level (0.12) had larger effects than transfusion (0.03). Results from several sensitivity analyses supported the main findings. The models showed good fit. CONCLUSIONS Preoperative anaemia had a larger impact on 5-year mortality than RBC transfusion. Differences in 5-year mortality were mainly associated with patient risk factors.

Objective.To describe the incidence of recovery of both vancomycin-resistant enterococci (VRE) and methicillin-resistantStaphylococcus aureus(MRSA) from culture of a single clinical specimen, to describe the clinical characteristics of patients from whom these specimens were recovered, and to identify the risk factors of these patients.Design.A retrospective cohort and case-control study.Setting.A tertiary care university hospital and referral center in Seoul, Korea.Methods.We identified 61 case patients for whom a single clinical specimen yielded both VRE and MRSA on culture, and 122 control patients for whom any clinical specimen yielded only VRE on culture. The control patients were selected by matching 2 :1 with the case patients for age, sex, and first date of sampling that led to isolation of VRE or both VRE and MRSA among 1,536 VRE-colonized patients from January 1, 2003, through December 31, 2006. To identify patient risk factors for the recovery of both VRE and MRSA in a single clinical specimen, we performed univariate comparisons between the 2 groups and then multivariate logistic regression analysis.Results.The incidence of recovery of both VRE and MRSA from culture of a single clinical specimen was 3.97% (for 61 of 1,536 VRE-colonized patients) over 4 years. Among these 82 single clinical specimens, the most common type was wound specimens (26.8%), followed by lower respiratory tract specimens (18.3%), urine specimens (17.1%), and catheter tips (15.9%). Of the 61 case patients, 14 (23.0%) had 2 or more single clinical specimens that yielded both VRE and MRSA on culture, and the longest interval from the first sampling that yielded both organisms to the last sampling that yielded both was 174 days. Independent patient risk factors for the presence of both VRE and MRSA in a single clinical specimen were chronic renal disease (odds ratio [OR], 7.00;P= .012), urinary catheterization (OR, 3.36;P= .026), and longer total cumulative duration of hospital stay within the previous year (OR, 1.03;P< .001).Conclusion.We confirmed that the recovery of VRE and MRSA from a single clinical specimen occurs continually. Because prolonged cell-to-cell contact can facilitate transfer ofvanA,close observation and surveillance for vancomycin-resistantS. aureus, especially among patients with risk factors for the recovery of both VRE and MRSA from a single clinical specimen, should be continued.

Suspicion Index

Elder mistreatment affects a considerable proportion of individuals older than 60 to 65 years of age and may include intentional abuse (physical, sexual, emotional, or financial) and neglect. As the proportion of the population that is older than 65 years of age increases, elder mistreatment will become an increasingly common issue. Only a minority of cases of elder abuse are reported; thus, an interview with the patient should be conducted in private if elder mistreatment is suspected. Patient risk factors for elder mistreatment include cognitive or behavioral impairment, poor physical health, and poor social supports. This review examines the approach to the patient, as well as definitive treatment, disposition, and outcomes for victims of elder abuse. The figure shows an algorithm for elder abuse assessment and intervention. Tables list types of elder abuse, factors predisposing to elder mistreatment, indicators of abuse, and the Elder Abuse Suspicion Index. This review contains 1 highly rendered figure, 4 tables, and 42 references.

В отечественной и зарубежной специализированной литературе отсутствуют исследования, посвященные изучению факторов риска развития неблагоприятного исхода у пациентов старшей возрастной группы с инсультассоциированной нозокомиальной пневмонией. Цель исследования - изучение факторов риска развития неблагоприятного клинического исхода у пациентов пожилого и старческого возраста с нозокомиальной пневмонией на фоне ОНМК. В исследование были включены 247 пациентов пожилого и старческого возраста (139 мужчин, 108 женщин, средний возраст - 74,1±6,3 года), госпитализированных с признаками ОНМК по ишемическому или геморрагическому типу. Согласно модели бинарной логистической регрессии, статистически значимо ассоциированы с развитием неблагоприятного исхода у изучаемой группы респондентов следующие параметры: возраст свыше 75 лет (p=0,011), степень инвалидизации по шкале mRS 3 (р=0,009), а также уровень С-РБ >100 мг/л (р=0,023) и мочевины >7 ммоль/л (р=0,044). Для снижения частоты встречаемости неблагоприятного клинического исхода у пациентов старшей возрастной группы с инсульт-ассоциированной нозокомиальной пневмонией необходимо верифицировать перечисленные выше клинико-лабораторные параметры на ранних этапах госпитализации. In the domestic and foreign specialized literature, there are no studies devoted to the study of risk factors of mortality in the older age patients with stroke-associated nosocomial pneumonia. The purpose of the study was to study the risk factors of adverse clinical outcomes in elderly and senile patients with stroke-associated nosocomial pneumonia. The study included 247 elderly and senile patients (139 men, 108 women, mean age - 74,1±6,3 years) who were hospitalized with signs of ischemic or hemorrhagic stroke. According to the binary logistic regression model, the following parameters are statistically significantly associated with adverse clinical outcomes in the studied group of respondents: age over 75 years (p=0.011), degree of disability according to mRS ≥3 (p=0,009), and C-reactive protein levels over 100 mg/l (p=0,023) and urea more than 7 mmol/l (p=0,044). In order to reduce the incidence of adverse clinical outcomes in patients of the older age group with stroke-associated nosocomial pneumonia, it is necessary to verify the above clinical and laboratory parameters at the early stages of hospitalization.
