ABSTRACT

Purpose: To evaluate demographic, clinical, and laboratory variables, and their associations with in-hospital mortality, among elderly internal medicine patients with nasogastric tube (NGT) feeding. Patients and Methods: Demographic, clinical, and laboratory data were collected retrospectively for 129 patients aged ≥80 years who initiated NGT feeding during their hospitalization in internal medicine wards. The data were compared between survivors and non-survivors. Multivariate logistic regressions were performed to identify the variables most significantly associated with in-hospital mortality. Results: The in-hospital mortality rate was 60.5%. Compared to survivors, non-survivors more often presented with pressure sores (P=0.005) and lymphopenia (P<0.001), were more often treated with invasive mechanical ventilation (P<0.001), and less often underwent geriatric assessment (P<0.001). Non-survivors demonstrated higher mean levels of C-reactive protein, and lower mean values of serum cholesterol, triglycerides, total protein, and albumin (P<0.001 for all comparisons). On multivariate analysis, the following variables were most significantly associated with in-hospital mortality in the entire cohort: the presence of pressure sores (odds ratio [OR], 4.34; 95% confidence interval [CI], 1.68-11.48; P=0.003) and lymphopenia (OR, 4.09; 95% CI, 1.51-11.08; P=0.006), and serum cholesterol (OR, 0.98; 95% CI, 0.96-0.99; P=0.003). Conclusion: Among elderly acutely ill patients who initiated NGT feeding during hospitalization, in-hospital mortality was extremely high. The factors most strongly associated with in-hospital mortality were the presence of pressure sores and lymphopenia, and lower serum cholesterol levels. These findings may provide useful prognostic information for decision-making regarding initiation of NGT feeding in elderly hospitalized patients.

ABSTRACT

BACKGROUND: Older adults frequently experience deconditioning following acute illnesses and require discharge from acute-care facilities to post-acute care facilities, which are limited. Our study aimed to explore predictors and outcomes associated with elongated length of stay (LOS) among older adults awaiting discharge to skilled nursing facility (SNF). METHODS: Retrospective cohort study was conducted at Shamir Medical Center, Israel, among adults (> 65 years) eligible for SNF. ROC curve analysis was used to determine prolonged LOS based on the risk to fall. Logistic and Cox regressions were used to analyze predictors and outcomes. RESULTS: Among 659 older adults awaiting transfer to SNF, 127 patients (24% among survivors of the index hospitalization) had prolonged LOS (> 12 days). The median age of patients was 82 years and 51% were females. The independent predictors for prolonged LOS were lower Norton index, higher MUST score, and admission from home. Prolonged LOS was independently associated with hospital-acquired infections, device related infections, and acquisitions of multidrug-resistant organisms. CONCLUSION: Prolonged LOS among older adults, awaiting transfer to SNF, should be suspected among non-institutionalized older adults with lower nutritional status and higher risk of pressure ulcers. The burden associated with establishing additional SNF beds, must be outweighed vs. the substantial infectious complications among awaiting older adults.

ABSTRACT

INTRODUCTION: Geriatric oncology is the clinical field of cancer treatment in older adults (above 65 years) and in the oldest-old (above 80 years). As age is the most significant risk factor for cancer, and with the aging of the population, there is a vast increase in the number of older cancer patients. BACKGROUND: The cases highlight the unique challenges in geriatric oncology: disease goals may differ; treatment toxicities are higher; the extensive use of prescription medication increases the chances of harmful drug-drug interactions; finally, older adults have unique psychosocial needs. Cancer treatment in older adults poses a risk of under-treatment as well as a risk for over-treatment. DISCUSSION: 'Onco-geriatrics' is a field in geriatrics in which a comprehensive geriatric assessment (CGA) is performed. The CGA focuses on specific therapeutic challenges of the older patient, on frailty and on toxicity-risk assessment. In geriatric oncology, a field in oncology aimed at providing care to older cancer adults, the most important first step is to define treatment intent - cure or palliation. Achievement of cure usually mandates a multi-disciplinary aggressive approach. Compromising any component of the treatment may hamper its success rate, yet administering the full therapeutic plan may be too toxic. Thus, each older patient being considered for definitive treatment must be discussed in a multi-disciplinary tumor board, and preferably assessed by a dedicated geriatrician prior to decision-making. In cases in which treatment intent is palliative - i.e. prolongation of survival and/or improvement in quality of life, we propose the following scheme - accurate definition of the palliative goal; adaptation of the therapeutic regime to the patient's geriatric condition; frequent clinical monitoring and flexibility in administration; continued treatment as long as palliative benefit is achieved, and early cessation in its absence. Such a scheme maintains the principal of 'primum non nocere' while facilitating the palliative benefit for older adults.

ABSTRACT

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a pandemic infection with substantial risk of death, especially in elderly persons. Information about the prognostic significance of functional status in older patients with COVID-19 is scarce. METHODS: Demographic, clinical, laboratory and short-term mortality data were collected of 186 consecutive patients aged ≥ 65 years hospitalized with COVID-19. The data were compared between 4 study groups: (1) age 65-79 years without severe functional dependency; (2) age ≥ 80 years without severe functional dependency; (3) age 65-79 years with severe functional dependency; and (4) age ≥ 80 years with severe functional dependency. Multivariate logistic regressions were performed to evaluate the variables that were most significantly associated with mortality in the entire sample. RESULTS: Statistically significant differences were observed between the groups in the proportions of males (p = 0.007); of patients with diabetes mellitus (p = 0.025), cerebrovascular disease (p < 0.001), renal failure (p = 0.003), dementia (p < 0.001), heart failure (p = 0.005), pressure sores (p < 0.001) and malignant disorders (p = 0.007); and of patients residing in nursing homes (p < 0.001). Compared to groups 1 (n = 69) and 2 (n = 28), patients in groups 3 (n = 32) and 4 (n = 57) presented with lower mean serum albumin levels on admission (p < 0.001), and were less often treated with convalescent plasma (p < 0.001), tocilizumab (p < 0.001) and remdesivir (p < 0.001). The overall mortality rate was 23.1 %. The mortality rate was higher in group 4 than in groups 1 - 3: 45.6 % vs. 8.7 %, 17.9% and 18.3 %, respectively (p < 0.001). On multivariate analysis, both age ≥ 80 years and severe functional dependency were among the variables most significantly associated with mortality in the entire cohort (odds ratio [OR] 4.83, 95 % confidence interval [CI] 1.88 - 12.40, p < 0.001 and OR 2.51, 95 % CI 1.02 - 6.15, p = 0.044, respectively). Age ≥ 80 years with severe functional dependency (group 4) remained one of the variables most significantly associated with mortality (OR 10.42, 95 % CI 3.27-33.24 and p < 0.001). CONCLUSIONS: Among patients with COVID-19, the association of severe functional dependency with mortality is stronger among those aged ≥ 80 years than aged 65-79 years. Assessment of functional status may contribute to decision making for care of older inpatients with COVID-19.

ABSTRACT

Background: Platelet distribution width (PDW) has demonstrated clinical significance in populations with specific disorders; its prognostic significance in internal medicine wards has not been investigated. Methods: Demographic, clinical and laboratory data were collected prospectively for 1036 internal medicine inpatients. The primary outcome was 90-day mortality, secondary outcomes were: treatment with mechanical ventilation, prolonged hospital stay, in-hospital death, and all-cause mortality following discharge. Data were assessed according to PDW values on admission ≤16.7% (group A) and >16.7% (group B). Results: Compared to group A patients (n = 273), group B patients (n = 763) were more likely to be older, admitted for cardio-cerebrovascular disorder, to present with comorbidities, to be mechanically ventilated, to have prolonged hospital stay and to die during the current hospitalization. The respective 90-day and total (median follow-up of 5 months) mortality rates were significantly higher in group B (13.2% and 16.3%) than in group A (6.6% and 9.5%), P < 0.01. On multivariate analysis, higher PDW values on admission predicted 90-day mortality and shortened survival (relative risks 1.58 and 1.26; 95% confidence intervals 0.89 - 2.78 and 0.97-1.64, respectively). Conclusion: Higher PDW values on admission to internal medicine wards are associated with a more severe clinical profile and increased risk of 90-day mortality.

ABSTRACT

PURPOSE: To investigate clinical characteristics and the prognostic significance of a prolonged international normalized ratio (INR) without obvious cause or anticoagulant treatment, in elderly inpatients. METHODS: Demographic, clinical, and laboratory data, in-hospital death and 30day-mortality were prospectively registered for 100 consecutive patients aged ≥75years admitted to an internal medicine ward for a variety of acute medical disorders, and compared according to normal (≤1.15) and prolonged (>1.15) INR on admission. Exclusion criteria were: anticoagulant therapy, disseminated intravascular coagulopathy, acute bleeding, liver disease, active malignant disorder, and known coagulopathy. RESULTS: Prolonged INR was found in 52% of patients. Patients with prolonged INR tended more likely to present with dementia and pressure sores than patients with normal INR. Moreover, patients with prolonged INR more often needed assisted feeding and presented lower mean levels of serum albumin on admission. In-hospital (21.2% vs. 6.2%) and 30-day (32.7% vs. 6.2%) mortality rates were significantly higher in patients with prolonged INR than those with normal INR. On stepwise logistic regression analysis, prolonged INR strongly predicted 30-day mortality (P=0.004, relative risk 1.67, 95% confidence interval 1.07-2.60). CONCLUSIONS: Prolonged INR without obvious cause or anticoagulant treatment is common among elderly patients admitted to an internal medicine ward, and is associated with a severe clinical profile. Prolonged INR is a powerful predictor of 30-day mortality. Assessment of INR my improve risk stratification for elderly inpatients.

ABSTRACT

BACKGROUND AND AIMS: We have previously shown that naso-gastric tube (NGT)-fed patients harbor pathogenic flora in their oropharynx. The purpose of this study was to examine comparatively the biochemical, immunological and enzymatic components of the saliva of these patients with that of orally-fed counterparts. METHODS: The study group consisted of 19 elderly NGT-fed patients and 18 comparable patients on oral feeding. Unstimulated whole saliva was collected and analyzed according to accepted methods for sodium, potassium, chloride, uric acid, total protein, albumin, amylase, lysozyme, and immunoglobulins, IgM, IgG, IgA, as well as secretory IgA. RESULTS: None of the above tested salivary components significantly differed between the two groups. Only uric acid levels were significantly lower (50%, p < 0.05) in NGT-fed patients. CONCLUSIONS: Uric acid is the main antioxidant component of saliva and, as such, it may be related to pathogenic bacterial colonization of the oropharynx in NGT-fed patients, with the risk of aspiration pneumonia.

ABSTRACT

BACKGROUND: In a previous study we showed that prolonged nasogastric tube feeding is associated with pathogenic oral flora. OBJECTIVE: To reexamine the impact of prolonged nasogastric tube feeding on the oral microbiota and to explore the salivary flow and composition in elderly patients in long-term care. METHODS: We compared a group of elderly patients fed by nasogastric tube with a control group of elderly patients in long-term care who are fed orally. Bacteriologic studies were performed by culturing samples from the oropharynx. Saliva studies included quantitative and biochemical analysis of basal and stimulated salivary flow. RESULTS: Bacteriologic studies performed in 90 patients revealed a significantly higher prevalence of gram-negative bacteria in nasogastric tube-fed patients (73% vs. 13%, P < 0.001). It is emphasized that Pseudomonas aeruginosa and Klebsiella pneumoniae were commonly and exclusively isolated from the oral flora of the nasogastric tube-fed patients (P < 0.001, P < 0.05). In the saliva studies performed on 23 nasogastric tube-fed and 21 control patients, basal and stimulated salivary flow was not significantly different in the two groups, however the ratio of stimulated to basal flow was reduced in the nasogastric tube-fed group (P < 0.05). Significant differences were also found in the concentrations of sodium, amylase, phosphor and magnesium. Noteworthy was the concentration of uric acid, the main non-enzymatic antioxidant of saliva, which was significantly lower in nasogastric-tube fed patients (P < 0.002). CONCLUSIONS: These findings suggest that prolonged nasogastric tube feeding is associated with pathologic colonization of the oroparynx and with alterations in the saliva that are related to the risk of aspiration pneumonia. Further research is called for, as well as a thorough revision of the existing oral cleansing procedures in these patients.

ABSTRACT

BACKGROUND: Aspiration of infected oropharyngeal content is the main cause of aspiration pneumonia. This complication, mainly related to gram-negative bacteria, threatens percutaneous enterogastric tube as well as nasogastric tube (NGT) fed patients. The objective of this study was to examine the oral microbiota of tuboenterally fed patients and compare it with that of orally fed counterparts. METHODS: Patients were recruited for this study from six nursing and skilled nursing facilities with an overall number of 845 beds. Enrolled were 215 patients: Group 1 consisted of 78 patients on NGT feeding, Group 2 consisted of 57 patients on percutaneous enterogastric tube feeding, and Group 3 consisted of 80 patients fed orally who were from the same facilities. Cultures were performed by sampling the oropharynx of each subject in order to identify gram-negative bacteria and Staphylococcus aureus. RESULTS: A high prevalence of potentially pathogenic isolations was found in tuboenterally fed patients: 81% in Group 1 and 51% in Group 2, as compared with only 17.5% in Group 3 (p <.0001). Pseudomonas aeruginosa was cultured from 31% of the subjects in Group 1 and 10% of Group 2, but in none of Group 3 (p <.001). Klebsiella and Proteus were isolated mainly from the NGT fed patients (p <.003). No correlation was found between the time duration on tube feeding or the presence of residual dentition and pathogenic microbiota. CONCLUSION: This study shows that tuboenteral feeding in elderly patients is associated with pathogenic colonization of the oropharynx. These findings are related to the risk of aspiration pneumonia and are compelling for the reevaluation of current oral cleansing procedures.
