Bacteremia in a multilevel geriatric hospital.

BACKGROUND: Bloodstream infection (BSI) is a major cause of morbidity and mortality in hospitals. Bacteremia in the elderly remains a diagnostic as well as a therapeutic challenge to the clinician. METHODS: We investigate the clinical features, microbiological characteristics, and outcome of bacteremic episodes in a mixed LTC elderly population in a multilevel geriatric hospital. Data of patients with the diagnosis of BSI (during 2 years) was collected retrospectively from the records of the bacteriology laboratory of a 400-bed multilevel geriatric hospital. RESULTS: During the 2 years of the study period, 3453 blood cultures have been performed; 368 positive blood cultures (10%) were detected in 309 patients. The total mortality rate at 2 weeks was 42%. One quarter of the deaths occurred in the first 3 days of the septic event (rapidly fatal period). Escherichia coli was the most common isolate (detected in 31% of cases). The second most common isolates were Staphylococcus aureus (19%; 63% of them MRSA) with a mortality of 39% and Proteus mirabilis (18%) with a 51% mortality rate. Urinary tract infection was the leading cause (70%), followed by decubitus ulcers (25%) and respiratory tract infections (12%). CONCLUSIONS: the number of elderly skilled patients with severe and complex conditions in LTC facilities is increasing and more infections complicated by bacteremia are expected, requiring high clinical suspicion, close surveillance, and adequate reporting.

QT interval disturbances in hospitalized elderly patients.

BACKGROUND: The QT interval reflects the total duration of ventricular myocardial repolarization. Its prolongation is associated with increased risk of polymorphic ventricular tachycardia, or torsade de pointes, which can be fatal. OBJECTIVES: To assess the prevalence of both prolonged and short QT interval in patients admitted to an acute geriatric ward. METHODS: This retrospective study included the records over 6 months of all patients hospitalized in an acute geriatric ward. Excluded were patients with pacemaker, bundle branch block and slow or rapid atrial fibrillation. The standard 12 lead electrocardiogram of each patient was used for the QT interval evaluation. RESULTS: We screened the files of 422 patients. QTc prolongation based on the mean of 12 ECG leads was detected in 115 patients (27%). Based on lead L2 only, QTc was prolonged in 136 (32%). Associated factors with QT prolongation were congestive heart failure and use of hypnotics. Short QTwas found in 30 patients (7.1%) in lead L2 and in 19 (4.5%) by the mean 12 leads. Short QT was related to a higher heart rate, chronic atrial fibrillation and schizophrenia. CONCLUSIONS: Our study detected QT segment disturbances in a considerable number of elderly patients admitted acutely to hospital. Further studies should confirm these results and clinicians should consider a close QT interval follow-up in predisposed patients.

Edema of the paretic hand in elderly post-stroke nursing patients.

Post-stroke edema of the paretic hand constitutes an additional, functional, and esthetic nuisance for the patient. Although often encountered in daily practice, it is not even mentioned in the stroke chapters of the various textbooks. The phenomenon is far from being elucidated and various aspects are still obscure. In this study we tried to estimate the extent of post-stroke hand edema (PSHE) in a sample of elderly patients. The study group consisted of 188 elderly post-stroke nursing patients with hemi or only hand paresis. Seventy, age matched, non-paretic patients were examined as controls. The basis of comparison was the difference in circumference between the two arms at three sites: mid-finger, hand, and wrist as measured in the control group. Values above two standard deviations (S.D.) of the mean difference in circumference of the controls, at two or three sites, were considered as edema. Edema of the paretic hand was detected in 37% of post-stroke patients. Most (about three-quarters), could be classified as simple PSHE, while the rest may have had reflex sympathetic dystrophy (RSD).

Postprandial hypotension in long-term care elderly patients on enteral feeding.

OBJECTIVES: To examine the prevalence and nature of postprandial hypotension (PPH) in orally fed (OF), nasogastric tube (NGT)-fed, and percutaneous endoscopic gastrostomy (PEG)-fed older people. DESIGN: Prospective comparative study. SETTING: Nursing and skilled nursing wards of three geriatrics hospitals. PARTICIPANTS: Three groups (OF, PEG, NGT) of long-term care patients (50 in each cohort) were enrolled. MEASUREMENTS: Blood pressure (BP) and heart rate measurements were obtained just before lunch and at 15-minute intervals for 90 minutes after the completion of the meal. The meals were similar in caloric content and composition. RESULTS: PPH was evidenced in 64 (43%) patients. No significant intergroup (OF, PEG, NGT) differences were present. In 68% of PPH patients, the systolic BP (SBP) drop appeared within 30 minutes, and 70% reached their systolic nadir at 60 minutes. In 31%, the SBP drop was registered on only one measurement, whereas in 25%, the drop was detected on five to six measurements. All parameters were without notable intergroup differences. CONCLUSION: In enterally fed elderly patients (NGT or PEG), the rate and pattern of PPH are similar and not significantly different from that observed in OF patients.

Colchicine therapy and the cognitive status of elderly patients with familial Mediterranean fever.

BACKGROUND: [corrected] Colchicine is widely used for treating gout and familial Mediterranean fever. However, studies in animal models have reported ill effects of colchicine on the central nervous system, including cognitive function. OBJECTIVES: To evaluate the cognitive status of elderly FMF patients on long-term colchicine treatment. METHODS: The study group consisted of 55 FMF patients aged 74 +/- 5, attending an FMF outpatient clinic and receiving colchicine treatment for 25.1 +/- 8.9 years. The Mini-Mental State Examination was used for cognitive evaluation. Patients' scores were compared with accepted age- and education-adjusted cutoff scores, population-based norms, and scores of a matched control group of 56 subjects. RESULTS: Individually, all colchicine-treated FMF patients scored well above the age- and education-corrected cutoff scores. Overall, there was a large difference, 5.0 +/- 1.6, from the expected cutoff points, in favor of the study group scores (P < 0.001). The individual scores of the control group were also above the cutoff points, however with a lower but still statistically significant difference (3.71 +/- 1.15 points, P < 0.001). Compared to population-based norms adjusted by age and education, the study group had significantly higher mean MMSE scores (27.2 +/- 2.2 vs. 25.5 +/- 2.4, P < 0.001). The control group's scores were also somewhat higher than expected, but not significantly so. CONCLUSIONS: Our results do not support the view that prolonged colchicine treatment may be associated with cognitive impairment. On the contrary, it is possible that long-term colchicine treatment may even confer protection against cognitive decline in patients with FMF.

Biodynamics of biofilm formation on nasogastric tubes in elderly patients.

BACKGROUND: We previously reported on the high propensity of pathogenic oral flora in the oropharynx of nasogastric tube-fed patients, and subsequently showed biofilm formation on the NGTs of these patients. There is a close relationship of biofilm and oropharyngeal colonization with pathogenic bacteria, aspiration pneumonia and antibiotic resistance. OBJECTIVES: To investigate the time relation between the insertion of a new NGT and formation of the biofilm. METHODS: We examined sequential samples on NGTs that were forcibly pulled out by the patients themselves during any of the 7 days after insertion. Scanning electron micrography and confocal laser scanning microscopy were used for biofilm detection. RESULTS: Biofilm was identified on 60% of the five samples of day 1 and on all the samples of the following days, by both microscopic methods. CONCLUSIONS: Biofilms form within a single day on most NGTs inserted for the feeding of elderly patients with dysphagia. Further research should be devoted to prevention of biofilm formation on NGTs.

Progressing stroke with neurological deterioration in a group of Israeli elderly.

Progressing stroke with neurological deterioration (PSND), i.e., neurological deterioration of patients during the first days following a stroke, although not an infrequent event, has hitherto been addressed only by few studies. This is the first investigation conducted in Israel with the aim to determine its prevalence and characteristics. Data regarding 140 patients with first ever stroke were collected prospectively between May 1999 and October 2000. All patients underwent a thorough daily neurological examination over the first 7 days, using the Canadian Neurological Scale. Most (90%), patients had hemiparesis, with dysarthria, aphasia and dysphagia being the most frequent associated neurological deficits. Thirty percent of the patients were on anti-aggregant therapy prior to the stroke. The prevalence of PSND was 23%. The 1-month in-hospital death rate of these PSND patients was 31%. Univariate analysis showed that previous anti-aggregant therapy, Parkinson's disease (PD), obesity, hyperlipidemia, and presence of aphasia were significantly more frequent in the PSND group. In addition, these patients arrived earlier to the emergency room. However, logistic regression analysis showed that only PD and obesity could possibly be considered as predictors for development of PSND. The prevalence as well as the death rate of PSND in this group of Israeli elderly is within the range reported in the literature. However, prior anti-aggregant treatment and PD, are here reported for the first time as associated conditions. Future research will possibly clarify the links between these entities and PSND.

Medical staff attitudes: views and positions regarding blood transfusion to terminally ill cancer patients.

Blood transfusion is a widely used supportive treatment of cancer patients, most of whom are anemic. In the particular subset of cancer patients that undergoes chemotherapy, blood transfusion is viewed as an essential part of supportive care. However, the place of blood transfusion in anemic terminally ill cancer patients is far less established. There are no well-defined blood transfusion guidelines ("transfusion trigger") for these patients. Hence, transfusion decisions are greatly influenced by the personal views of the medical team. Therefore, a mail survey of 500 physicians (from several specialties) and nurses was initiated to assess their personal opinions on this topic. The overall response rate was relatively high (70%). There was broad agreement that blood transfusions, as a rule, should not be withheld from terminal cancer patients. On the other hand, only nurses were of the opinion that these patients should be transfused "as usual." Significantly, there was but a slight majority (53% of participants) that was of the opinion that transfusions to these patients do not prolong suffering. There emerged a short list of agreed-on suggestions for blood transfusion--namely, Hb level < or = 7 mg/dL, active bleeding (acute and/or occult), functional deterioration of the patient, presence of anemia resulting from chemotherapy, anginal symptoms, dyspnea, and worsening congestive heart failure. The agreed-on suggestions for transfusions in terminally ill cancer patients may serve as a reasonable physician standard for this complex clinical, medical-legal, and emotional issue.

Management of adverse clinical events by duty physicians in a nursing home.

BACKGROUND AND AIMS: The nature of adverse clinical events (ACE) during duty hours (16:00-08:00 and holidays), as well as the way they are addressed by duty physicians (DP) in a nursing home (NH) are the subject of this study. METHODS: Data, including medical details concerning ACEs and the resultant referrals to hospital, were collected prospectively during 183 consecutive days in a 90-bed NH. RESULTS: Ninety-six residents experienced 370 ACEs, representing an average of one for every 44.5 patient days. The highest rate of events was during evening hours (18:00-21:00). The most prevalent ACE was fever (32%). Most cases (53%) were treated by the DPs on site. No intervention was needed in 19% of cases, whereas 28% of ACEs (104 cases) were referred to the Emergency Room (ER) of a general hospital. Sixty-six percent of these were actually admitted. The rate of ER referral of residents was one for every 158 patient days. About 40% of the referred patients had been discharged from hospital the previous week. High fever was the commonest cause for referral: 47%. During the working hours of the study period, the rate of referral by the staff physician was only 1 for every 915 patient days. Only 17% of these had high fever. CONCLUSIONS: Evening rounds by staff physicians, strengthening of working relations with hospital physicians, as well as fostering intravenous treatment in NHs, are suggested as means for reducing hospital transfers. A standardized method for the reporting of ACEs and referrals to hospitals should be adopted in order to facilitate comparisons between NHs and to evaluate its use as a quality indicator.

[Relatives' satisfaction with the care of elderly patients in skilled nursing wards].

BACKGROUND: Skilled Nursing Wards (SNW) in Israel are purposely equipped and staffed for treatment of patients that, in addition to functional dependence, suffer from active diseases which require close medical supervision. Patients' surveys on satisfaction with health care are increasingly accepted as an element of quality assessment. However, given the high rate of communication disorders present in these patients, this method is not feasible for use in SNWs. OBJECTIVE: We initiated a survey of patients' relatives--based on a questionnaire specifically designed to reflect their satisfaction with the level of care provided. METHODS: Respondents were asked to rank their level of satisfaction with medical, nursing and structural aspects of the care in the SNW on a 1-5 Likert Scale. RESULTS: Relatives of 147 SNW residents answered the questionnaire. The overall level of satisfaction was high, all components being ranked at 4.2 or above. Four point fifty-five was the average rating given to the medical component of the care, 4.39 to the nursing aspect and 4.32 to the structural section. Five points were awarded to the medical component by 60% of the participants, to the nursing element by 55% of respondents and to the structural section by 40% of respondents. No differences were observed between the rankings of frequent and less frequent visitors. All respondents were highly cooperative and expressed their appreciation of the initiative to perform a satisfaction survey. CONCLUSION: The results show that the families of the skilled nursing patients that participated in this study are satisfied with the health care provided to their relatives. Such surveys contribute to the quality of care and should be considered for routine/periodical use in long-term care settings.

Increased incidence of pathological and clinical prostate cancer with age: age related alterations of local immune surveillance.

PURPOSE: The incidence of prostate cancer dramatically increases with age. The etiology still awaits elucidation, and the question as to why it is so prominently a disease of aging remains unanswered. We offer an explanation by suggesting an age related deficient immune surveillance. MATERIALS AND METHODS: Reports published in the scientific literature with relevance to cancer and immunity, immune senescence, blood-prostate barrier and immune privilege were identified using MEDLINE. RESULTS: The existence of a blood-prostate barrier is a fair assumption, and the prostate may be considered an immune privileged site. With aging the prostate, a priori immunologically under surveilled, probably becomes more and more so. There is impaired function, transmigration and probably penetration into the gland of natural killer and other immune competent cells due to the onset of immune senescence coupled with impaired diapedesis and possible age related alterations in the blood-prostate barrier. CONCLUSIONS: Apparently, with aging the immune surveillance of the already immune privileged prostate is progressively and further affected. This condition may result in the inability of the gland to eradicate emergent malignant cells.

Anemia, serum vitamin B12, and folic acid in patients with rheumatoid arthritis, psoriatic arthritis, and systemic lupus erythematosus.

OBJECTIVE: Although anemia is frequent in inflammatory rheumatic diseases, data regarding vitamin B12 status is scarce. The purpose of this study was to analyze the incidence and nature of B12 and folic acid (FA) deficiencies in a cohort of rheumatic patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and systemic lupus erythematosus (SLE). METHODS: Levels of B12, FA, and parameters of anemia were recovered or examined in 276 outpatients. In those with recent findings of low serum B12 levels, further studies of serum homocysteine (Hcy) and urine methylmalonic acid (MMA) levels were performed. RESULTS: The incidence of anemia was high: 49%, 46%, and 35%, in RA, SLE, and PsA, respectively. Low levels of serum B12 were also frequent (24%), with almost similar occurrence in the three disease groups. Deficiency in FA was rare (<5%). Mean levels of both vitamins did not differ significantly among the three groups. No correlation between serum B12 levels and anemia was found. In the 15 patients with recently detected low B12 levels, Hcy and MMA were evaluated before and following B12 therapy. In ten of them, baseline Hcy levels were high, while MMA was increased in one patient only. Response to B12 administration, i.e., a decrease in Hcy and/or MMA levels, was noticed in four patients only, suggesting that only 26% of the low-serum-B12 patients had true B12 deficiency. CONCLUSIONS: The incidences of anemia and decreased serum B12 levels were high in these three groups of rheumatic patients. However, true tissue deficiency seems to be much rarer.

Geriatric medical education in Israel.

In this article we will focus on geriatric medical education in Israel and will review our experience in this field. A coordinated effort of the Ministry of Health and the Israeli Medical Association led to the establishment of a modern geriatric system and to the recognition of geriatrics as a medical specialty in the early 1980s. All four Israeli medical schools joined this effort by introducing geriatrics in the undergraduate studies. Several innovative models for teaching geriatrics to medical students and for postgraduate training have been developed and implemented. The growing body of skills and knowledge available, and their application for competent care of the elderly, constitute a compelling impetus for the further development of a high-quality geriatric medical education.

Satisfaction with the care of institutionalized psychogeriatric patients, as reflected by a survey of their relatives.

The patients' satisfaction is an important aspect of quality of care assessment in long-term care institutions. However, many psychogeriatric patients are institutionalized at an advanced stage of their disease, when they are unable to communicate properly and cannot be questioned about their satisfaction with the care received in these psychogeriatric settings. Therefore we initiated a survey of patients' relatives based on a questionnaire purposely designed, to evaluate their satisfaction with the medical, nursing and structural components of the institutional care. The relatives of 101 patients, representing 79% of the patients in four psychogeriatric wards, responded to the questionnaire. The level of satisfaction with the care was high, as reflected by the fact that over 75% of the respondents rated the overall question about satisfaction with the medical, nursing, and structural components with the maximum of five points. The high correlation between the summative and the overall satisfaction supports and even strengthens this view. Another finding was the reluctance of most relatives to be involved in the personal care of the patients. Our study concluded that the relatives do appreciate the efforts of the staff and understand the constraints imposed by the nature of the patients' condition. Moreover, both families and staff welcomed this study and mentioned its contribution in improving communication.

Gender-associated findings in postmortem examinations of elderly patients: an increased rate of pulmonary embolism in women.

BACKGROUND: While age at death is on the rise, the number of postmortem examinations is declining and is disproportionately low among the elderly population. Research on, the subject of gender-associated pathology in the elderly is also scarce. OBJECTIVE: To seek eventual gender-related differences in autopsies of elderly patients. METHODS: We analyzed the data extracted from a published report on 93 PMEs performed at a geriatric hospital during the past 20 years. RESULTS: Ninety-three autopsies, representing 1.2% of the 8,101 deaths during these 20 years, were performed. Forty-five of the deceased were women and 48 were men. The incidence of pulmonary embolism was significantly higher in women (28%) than in men (10%) (P < 0.02). There was no significant difference in the gender distribution of the other diagnoses. CONCLUSION: Gender distribution of PME-based causes of death in elderly patients revealed a significant rate of pulmonary embolism in women. A thorough search of the medical literature revealed two previous studies with similar findings. Further research will determine whether pulmonary embolism is more frequent or whether it has a worse prognosis in frail elderly women.
