Will-to-Live and Self-Rated Health in Older Hospitalized Patients Are Not Predictive for Short-Term Mortality.

Background: Self-assessed will-to-live and self-rated health are associated with long-term survival in community-dwelling older persons but have not been examined in frailer older patients in relation to short-term prognosis. The aim was to explore whether will-to-live and self-rated health are predictive for six-month mortality and can guide ceiling of treatment decisions in hospitalized patients in an acute geriatric ward. We included the Surprise Question as reference, being a well-established clinical tool for short-term prognostication. Methods: This multicentric prospective study included patients of 75 years and older admitted at acute geriatric wards of two Belgian hospitals. Will-to-live and self-rated health were scored on a Likert scale (0-5, 0-4) and assessed by junior geriatricians. The senior geriatricians answered the Surprise Question for clinical judgment of prognosis. Receiver-operator characteristic (ROC) curves were constructed to determine diagnostic accuracy. For time-dependent analysis, Cox regression was performed with adjustment for age and gender. Results: Of 93 included patients in the study, 69 were still alive after six months and 24 died, resulting in a six-month mortality of 26%. The mean age was 86 years (range 75-100), 67% of the patients were women. Median will-to-live and self-rated health were 3 (moderate and good). Both will-to-live and self-rated health were not predictive for six-month mortality (area under the ROC curve [AUC] 0.496, p = 0.951 for will-to-live; 0.447, p = 0.442 for self-rated health) as opposed to Surprise Question (AUC 0.793, p < 0.001). After correction for sex and age, the hazard ratio of six-month mortality was 0.92 for will-to-live (p = 0.667), 0.86 for self-rated health (p = 0.548), and 10.28 for Surprise Question (p < 0.001). Conclusion: Will-to-live and self-rated health are not predictive for six-month mortality in patients admitted to the acute geriatric ward, unlike prognostic tools such as Surprise Question.

Sanitary installations and wastewater plumbing as reservoir for the long-term circulation and transmission of carbapenemase producing Citrobacter freundii clones in a hospital setting.

BACKGROUND: Accumulating evidence shows a role of the hospital wastewater system in the spread of multidrug-resistant organisms, such as carbapenemase producing Enterobacterales (CPE). Several sequential outbreaks of CPE on the geriatric ward of the Ghent University hospital have led to an outbreak investigation. Focusing on OXA-48 producing Citrobacter freundii, the most prevalent species, we aimed to track clonal relatedness using whole genome sequencing (WGS). By exploring transmission routes we wanted to improve understanding and (re)introduce targeted preventive measures. METHODS: Environmental screening (toilet water, sink and shower drains) was performed between 2017 and 2021. A retrospective selection was made of 53 Citrobacter freundii screening isolates (30 patients and 23 environmental samples). DNA from frozen bacterial isolates was extracted and prepped for shotgun WGS. Core genome multilocus sequence typing was performed with an in-house developed scheme using 3,004 loci. RESULTS: The CPE positivity rate of environmental screening samples was 19.0% (73/385). Highest percentages were found in the shower drain samples (38.2%) and the toilet water samples (25.0%). Sink drain samples showed least CPE positivity (3.3%). The WGS data revealed long-term co-existence of three patient sample derived C. freundii clusters. The biggest cluster (ST22) connects 12 patients and 8 environmental isolates taken between 2018 and 2021 spread across the ward. In an overlapping period, another cluster (ST170) links eight patients and four toilet water isolates connected to the same room. The third C. freundii cluster (ST421) connects two patients hospitalised in the same room but over a period of one and a half year. Additional sampling in 2022 revealed clonal isolates linked to the two largest clusters (ST22, ST170) in the wastewater collection pipes connecting the rooms. CONCLUSIONS: Our findings suggest long-term circulation and transmission of carbapenemase producing C. freundii clones in hospital sanitary installations despite surveillance, daily cleaning and intermittent disinfection protocols. We propose a role for the wastewater drainage system in the spread within and between rooms and for the sanitary installations in the indirect transmission via bioaerosol plumes. To tackle this problem, a multidisciplinary approach is necessary including careful design and maintenance of the plumbing system.

Clinical decision-making in older patients with cancer: a cross-sectional single-centre study to assess the impact of clinical judgement and patient preferences.

OBJECTIVE: The heterogeneity in the population of older patients with cancer makes clinical decision-making difficult. We investigated the agreement between the G8 score and clinical judgment in frailty assessments, determined the impact of a life-expectancy calculator, and explored patient and caregiver preferences towards the treatment goal. METHODS: Patients aged ≥75 years in need of new oncological treatment were prospectively enrolled between June 2020 and February 2021. Frailty was estimated by the oncologist and caregiver and compared to the G8 estimation. We examined whether the oncologist changed the fit/frail estimation based on life expectancy calculated using the ePrognosis tool. The main treatment goals, either longevity or quality of life (QoL), from the patient's and caregiver's perspective were noted and compared. RESULTS: Forty-nine patients were included in the analysis. Comparison of the oncologist's and the caregiver's frailty estimation with the G8 assessment showed agreement and a Kappa coefficient of 58.3% (0.231) and 60% (0.255), respectively. The ePrognosis score and the odds of change in the frailty estimation by the oncologist showed no correlation. Regarding preferences, 28 (57.1%) and 17 (34.7%) patients and eighteen (47.3%) and seventeen (44.7%) caregivers chose longevity and QoL, respectively. The observed agreement and Kappa coefficient were 78.8% and 0.578. CONCLUSION: Compared to the G8 assessment, frailty was underestimated by both oncologists and caregivers. Most of the patients chose longevity over QoL, and the preferences between the patient and the caregiver matched in the majority of cases.

Prognostic value of the Surprise Question for one-year mortality in older patients: a prospective multicenter study in acute geriatric and cardiology units.

OBJECTIVES: To determine the prognostic value of the Surprise Question (SQ) in older persons. METHODS: A multicenter prospective study, including patients aged 75 years or older admitted to acute geriatric (AGU) or cardiology unit (CU). The SQ was answered by the treating physician. Patients or relatives were contacted after 1 year to determine 1-year survival. Logistic regression was used to explore parameters associated with SQ. Summary ROC curves were constructed to obtain the pooled values of sensitivity and specificity based on a bivariate model. RESULTS: The SQ was positive (death within 1 year is no surprise) in 34.7% AGU and 33.3% CU patients (p = 0.773). Parameters associated with a positive SQ were more severe comorbidity, worse functionality, significant weight loss, refractory symptoms and the request for palliative care by patient or family. One-year mortality was, respectively, 24.9% and 20.2% for patients hospitalized on AGU and CU (p = 0.319). There was no difference in sensitivity or specificity, respectively, 64% and 77% (AUC 0.635) for AGU versus 63% and 76% (AUC 0.758) for CU (p = 0.870). A positive SQ is associated with a significant shorter time until death (HR 5.425 (95% CI 3.332-8.834), p < 0.001) independently from the ward. CONCLUSION: The Surprise Question is moderately accurate to predict 1-year mortality in older persons hospitalized on acute geriatric and cardiologic units.

Supportive and Palliative Care Indicators Tool prognostic value in older hospitalised patients: a prospective multicentre study.

BACKGROUND: An increasing number of older patients are hospitalised. Prognostic uncertainty causes hospital doctors to be reluctant to make the switch from cure to care. The Supportive and Palliative Care Indicators Tool (SPICT) has not been validated for prognostication in an older hospitalised population. AIM: To validate SPICT as a prognostic tool for risk of dying within one year in older hospitalised patients. DESIGN: Prospective multicentre study. Premorbid SPICT and 1-year survival and survival time were assessed. SETTING/PARTICIPANTS: Patients 75 years and older admitted at acute geriatric (n=209) and cardiology units (CUs) (n=249) of four hospitals. RESULTS: In total, 59.3% (124/209) was SPICT identified on acute geriatric vs 40.6% (101/249) on CUs (p<0.001). SPICT-identified patients in CUs reported more functional needs and more symptoms compared to SPICT non-identified patients. On acute geriatric units, SPICT-identified patients reported more functional needs only.The HR of dying was 2.9 (95% CI 1.1 to 8.7) in SPICT-identified versus non-identified after adjustment for hospital strata, age, gender and did not differ between units. One-year mortality was 24% and 22%, respectively, on acute geriatric versus CUs (p=0.488). Pooled average sensitivity, specificity and partial area under the curve differed significantly between acute geriatric and CUs (p<0.001), respectively, 0.82 (95%CI 0.66 to 0.91), 0.49 (95%CI 0.40 to 0.58) and 0.82 in geriatric vs 0.69 (95% CI 0.42 to 0.87), 0.66 (95% CI 0.55 to 0.77) and 0.65 in CUs. CONCLUSIONS: SPICT may be used as a tool to identify older hospitalised patients at risk of dying within 1 year and who may benefit from a palliative care approach including advance care planning. The prognostic accuracy of SPICT is better in older patients admitted at the acute geriatric versus the CU.

Adherence to recommendations of inpatient geriatric consultation teams: a multicenter observational study.

PURPOSE: Inpatient geriatric consultation teams (IGCTs) provide recommendations for the care of older patients hospitalized on non-geriatric wards based on comprehensive geriatric assessment. The lack of adherence to their recommendations hinders the potential impact of IGCTs. We evaluated the adherence to IGCT recommendations and determined which team and recommendation characteristics are related to higher adherence rates. METHODS: Multicenter observational study in older adults aged ≥ 75 years admitted to an acute non-geriatric ward. Demographic and adherence data were collected for 30 consecutive patients. A cross-sectional survey mapped team and organizational characteristics of the participating IGCTs. RESULTS: Analyses were conducted in 278 patients (51.4% male, mean age 82.5 years, and median length of stay 10 days). There was a median number of 3 recommendations (range 1-13) per patient. The overall adherence rate was 69.7%. Recommendations related to 'social status' (82.4%) and 'functional status/mobility' (73.3%) were best adhered to. Recommendations related to 'medication' (53.2%) and 'nutritional status' (59.1%) were least adhered to. Adherence rates increased if recommendations were given to allied health professionals (OR = 6.37, 95% CI = 1.15-35.35) or by more experienced IGCTs (OR = 1.34, 95% CI = 1.04-1.72) and decreased when more recommendations were given (OR = 0.51, 95% CI = 0.33-0.80). CONCLUSION: Adherence rate to IGCT recommendations increased if given to allied health professionals or by more experienced IGCTs and when fewer recommendations were given. Study replication in an international multicenter study with a larger number of centers and evaluating the quality of the recommendations is suggested.

Can usual gait speed be used as a prognostic factor for early palliative care identification in hospitalized older patients? A prospective study on two different wards.

BACKGROUND: Timely palliative care in frail older persons remains challenging. Scales to identify older patients at risk of functional decline already exist. However, factors to predict short term mortality in older hospitalized patients are scarce. METHODS: In this prospective study, we recruited patients of 75 years and older at the department of cardiology and geriatrics. The usual gait speed measurement closest to discharge was chosen. We used the risk of dying within 1 year as parameter for starting palliative care. ROC curves were used to determine the best cut-off value of usual gait speed to predict one-year mortality. Time to event analyses were assessed by COX regression. RESULTS: On the acute geriatric ward (n = 60), patients were older and more frail (assessed by Katz and iADL) in comparison to patients on the cardiology ward (n = 82); one-year mortality was respectively 27 and 15% (p = 0.069). AUC on the acute geriatric ward was 0.748 (p = 0.006). The best cut-off value was 0.42 m/s with a sensitivity and specificity of 0.857 and 0.643. Slow walkers died earlier than faster walkers (HR 7.456, p = 0.011), after correction for age and sex. On the cardiology ward, AUC was 0.560 (p = 0.563); no significant association was found between usual gait speed and survival time. CONCLUSIONS: Usual gait speed may be a valuable prognostic factor to identify patients at risk for one-year mortality on the acute geriatric ward but not on the cardiology ward.

Validation of the G8 screening tool in older patients with aggressive haematological malignancies.

BACKGROUND: Incidence rates of haematological malignancies increase with age. In these older cancer patients, important information may be missed without a Comprehensive Geriatric Assessment (CGA). A validated screening instrument is needed to identify those patients for whom a CGA would be beneficial. The G8 has recently been validated as a screening tool for older cancer patients in need of a CGA. OBJECTIVES: To test the performance of the G8 screening tool in older patients with aggressive haematological malignancies to identify those who would benefit from a CGA. METHODS: Cross-sectional study of patients ≥70 years with a recently diagnosed haematological malignancy. G8, CGA (including six questionnaires) and Cumulative Illness Rating Scale for Geriatrics (CIRS-G) were completed in each patient. The CGA was considered abnormal when at least one questionnaire showed an impaired score. RESULTS: Fifty patients with median age of 76 years were included; 88% (N = 44) had an abnormal CGA. ROC curve analyses revealed a G8 score ≤14 obtained a sensitivity of 89% (95% CI 75-96) and a specificity of 100% (95% CI 54-100), suggesting an optimal cut-off point. AUC ± SE was 0.949 ± 0.030. Inclusion of comorbidity in the CGA did not change the performance of the G8 (0.943 ± 0.034; P = 0.895). CONCLUSION: The G8 can be used as a valid screening tool in older patients with aggressive haematological malignancies to identify those patients who would benefit from a CGA. Comorbidity should be assessed routinely and independently of the G8.

Prevalence of symptoms in older cancer patients receiving palliative care: a systematic review and meta-analysis.

CONTEXT: Symptom control is an essential part of palliative care and important to achieve optimal quality of life. Studies showed that patients with all types of advanced cancer suffer from diverse and often severe symptoms. Research focusing on older persons is scarce because this group is often excluded from studies. Consequently, it is unclear which symptoms older palliative care patients with cancer experience and what is the prevalence of these symptoms. To date, no systematic review has been performed on the prevalence of symptoms in older cancer patients receiving palliative care. OBJECTIVES: The objective of this systematic review was to search and synthesize the prevalence figures of symptoms in older palliative care patients with cancer. METHODS: A systematic search through multiple databases and other sources was conducted from 2002 until April 2012. The methodological quality was evaluated. All steps were performed by two independent reviewers. A meta-analysis was performed to pool the prevalence of symptoms. RESULTS: Seventeen studies were included in this systematic review. Thirty-two symptoms were identified. The prevalence of these symptoms ranged from 3.5% to 77.8%. The most prevalent symptoms were fatigue, excretory symptoms, urinary incontinence, asthenia, pain, constipation, and anxiety and occurred in at least 50% of patients. CONCLUSION: There is a high degree of uncertainty about the reported symptom prevalence because of small sample sizes, high heterogeneity among studies, and the extent of instrument validation. Research based on rigorous methods is needed to allow more conclusive results.

The process of decline in advanced activities of daily living: a qualitative explorative study in mild cognitive impairment.

BACKGROUND: The notion of "minimal impairment in instrumental activities of daily living (i-ADL)" is important in the diagnosis of mild cognitive impairment (MCI), but is presently not adequately operationalized. ADL is stratified according to difficulty, complexity, and also to vulnerability to early cognitive changes in a threefold hierarchy: basic activities of daily living (b-ADL), i-ADL, and advanced activities of daily living (a-ADL). This study aims to gain a deeper understanding of the functional decline in the process of MCI. METHODS: In a qualitative design, 37 consecutive patients diagnosed with amnestic (a)-MCI and their proxies were interviewed at two geriatric day hospitals. Constant comparative analysis was used for the analysis. RESULTS: The a-ADL-concept emerged as important in the diagnosis of MCI. All participants were engaged in a wide range of activities, which could be clustered according to the International Classification of Functioning, Disability and Health (ICF). Participants reported subtle difficulties in performance. A process of functional decline was identified in which adaptation and coping mechanisms interacted with the process of reduced skills, leading to an activity disruption and an insufficiency in functioning. CONCLUSION: This study asserts the inclusion of an evaluation of a-ADL in the assessment of older persons. When evaluating ADL at three levels (b-ADL, i-ADL, and a-ADL), all the activities one can perform in daily living are covered.

[Geriatric day hospital: what evidence? A systematic review]. / L'hôpital de jour gériatrique : quels objectifs, quelle organisation, quelle efficience ? Une revue de la littérature.

A systematic review of the international literature concerning the organisation of the Geriatric Day Hospital (GDH) was performed. From 1987 till now, few papers were found describing the activity and the effectiveness of the GDH. All the studies comparing specific geriatric approaches to regular medicine demonstrate the efficiency of geriatric care, particularly the geriatric assessment. So, with a degree of evidence 1a, a better outcome is found for patients undergoing a geriatric assessment and intervention, compared to patients having no geriatric assessment at all. However, there is no evidence of benefit for the geriatric day hospital compared to patients treated in a geriatric ward or other location of geriatric care. Moreover, there is no clear consensus on the settings and activities of a geriatric day hospital. Terms as day unit, day hospital, day care, are used interchangeably and are not always covering the same activity. The same remark can be made on the exact composition of the geriatric multidisciplinary team and its role. However nurses and paramedical workers are always mentioned as all performing geriatric assessment. The diagnostic activities on the GDH are seldom described and studied. More information is available on rehabilitation activity, often developed in specific patient populations such as stroke patients, dementia patients, cardiac patients or patients with other chronic diseases. In this selected patient populations positive effects on outcome are shown in the GDH (level of evidence 1a). Another problem is the heterogeneity of the population. For scientific reason the GDH should focus on organising care for specific medical problems. Diseases as dementia, stroke, cardiac insufficiency, could be good models to investigate the efficiency of geriatric assessment and interventions within the setting of a GDH.

Polymorphisms in base-excision repair and nucleotide-excision repair genes in relation to lung cancer risk.

Polymorphisms in DNA repair genes may be associated with differences in DNA repair capacity, thereby influencing the individual susceptibility to smoking-related cancer. We investigated the association of 10 base-excision and nucleotide-excision repair gene polymorphisms (XRCC1 -77 T/C, Arg194Trp, Arg280His and Arg399Gln; APE1 Asp148Glu; OGG1 Ser326Cys; XPA -4 G/A; XPC PAT; XPD Asp312Asn and Lys751Gln) with lung cancer risk in Caucasians. Genotypes were determined by PCR-RFLP and PCR-single base extension assays in 110 lung cancer patients and 110 age- and sex-matched controls, and the results were analyzed using logistic regression adjusted for relevant covariates. A significant association between the APE1 Asp148Glu polymorphism and lung cancer risk was found, with adjusted odds ratios (OR) of 3.38 (p=0.001) for the Asp/Glu genotype and 2.39 (p=0.038) for the Glu/Glu genotype. Gene-smoking interaction analyses revealed a statistically significant interaction between cumulative cigarette smoking and the XRCC1 Arg399Gln and XPD Lys751Gln polymorphisms: these polymorphisms were significantly associated with lung cancer in nonsmokers and light smokers (<25 PY; OR=4.92, p=0.021 for XRCC1 399 Gln/Gln; OR=3.62, p=0.049 for XPD 751 Gln/Gln), but not in heavy smokers (> or =25 PY; OR=0.68, p=0.566 for XRCC1 399 Gln/Gln; OR=0.46, p=0.295 for XPD 751 Gln/Gln). Both the XRCC1 Arg194Trp and Arg280His as well as the OGG1 Ser326Cys heterozygous genotypes were associated with a significantly reduced risk for lung cancer (OR=0.32, p=0.024; OR=0.25, p=0.028; OR=0.51, p=0.033, respectively). No associations with lung cancer risk were found for the XRCC1 -77 T/C, the XPA -4 G/A and the XPC PAT polymorphisms. In conclusion, the APE1 Asp148Glu polymorphism is highly predictive for lung cancer, and cumulative cigarette smoking modifies the associations between the XRCC1 Arg399Gln and the XPD Lys751Gln polymorphisms and lung cancer risk.

Echocardiographically estimated left ventricular end-diastolic and right ventricular systolic pressure in normotensive healthy individuals.

AIM: To study the effect of aging on and the relationship between echocardiographically estimated left ventricular (LV) filling pressure and estimated right ventricular (RV) systolic pressure among healthy normotensive individuals. METHODS: We analyzed 249 healthy individuals (aged 18-82 years, 52% men) with normal echocardiographic findings and reliably measurable tricuspid regurgitation gradients. Subjects with blood pressure >140/90 mmHg and/or LV hypertrophy were excluded. LV & RV dimensions and LV mass were measured with M-mode echocardiography. Atrial (A) volumes were determined with the area-length method. Diastolic function was assessed with transmitral Doppler and mitral annulus tissue Doppler. The ratio of transmitral early peak velocity to early diastolic mitral annulus velocity (E/E') was used as estimation of LV filling pressure. The transtricuspid Doppler gradient was used to estimate RV end-systolic pressure. RESULTS: Even in normotensive individuals aging was accompanied by an increase in LV mass and LA dimensions and an increase in relaxation abnormalities. E/E' increased with every decade: from 7.8 for age 18-35 years to 10.9 for age > or =75 years (p<0.0001) as did the transtricuspid gradient: from 18.3 mmHg for age 18-35 years to 25.8 mmHg for age > or =75 years (p<0.0001). Linear regression showed that estimated RV systolic pressure was independently predicted by age, LA volume, LV systolic function and E/E'. CONCLUSION: Among normotensive healthy individuals both E/E' and tricuspid regurgitation gradients increase significantly with aging. Moreover the E/E' ratio was independently predicting the tricuspid regurgitation gradient. These findings support the need for further studies defining age specific normal values.

Incremental prognostic value of combined perfusion and function assessment during myocardial gated SPECT in patients aged 75 years or older.

BACKGROUND: Perfusion and functional data obtained during gated single photon emission computed tomography (SPECT) have proven prognostic value in the middle-aged patient population. The aim of this study was to investigate whether perfusion and functional cardiac gated SPECT data have prognostic value in patients aged 75 years or older. METHODS AND RESULTS: We studied clinical and gated SPECT predictors of cardiac and all-cause death in 294 patients aged 75 years or older with known or suspected coronary artery disease who were referred for tetrofosmin cardiac gated SPECT imaging. Summed perfusion scores were calculated in a 17-segment model by use of commercially available software (4D-MSPECT). Left ventricular functional data were calculated by use of QGS gated SPECT software. The median age of the study population was 78 years (range, 75-91 years). There were 160 men (54%) and 134 women (46%). During a median follow-up of 25.9 months (range, 1.8-36 months), 47 patients (16%) died (27 cardiac deaths). In a multivariate Cox proportional hazards regression analysis, the summed rest score (chi2 gain = 8.0, P = .009), transient ischemic dilatation index (chi2 gain = 6.3, P = .012), and resting left ventricular ejection fraction (chi2 gain = 7.0, P = .030) were independent predictors of all-cause death. The summed rest score (chi2 gain = 8.2, P = .004) and resting end-systolic volume (chi2 gain = 13.7, P = .005) were independent predictors of cardiac death. CONCLUSIONS: This study showed that gated SPECT left ventricular functional data assessed during myocardial gated SPECT provide independent and incremental information above clinical and perfusion SPECT data for the prediction of cardiac and all-cause death in patients aged 75 years or older referred for myocardial SPECT imaging.

Effects of age, gender, and left ventricular mass on septal mitral annulus velocity (E') and the ratio of transmitral early peak velocity to E' (E/E').

The ratio of the transmitral early peak velocity (E) evaluated by conventional Doppler imaging over early diastolic mitral annulus velocity (E') evaluated by tissue Doppler imaging has been proposed as a noninvasive marker for left ventricular filling pressure. We evaluated 174 normal patients and 86 patients with hypertension and LV hypertrophy to assess the effects of age, gender, and left ventricular hypertrophy on E' and E/E'. Age appeared to be the strongest determinant of E' and E/E', suggesting that in normal patients and in those with left ventricular hypertrophy, age-dependent cut-off values should be considered.

The role of ultrasonography in the assessment of renal function in the elderly.

BACKGROUND: Ageing is associated with a progressive loss of renal mass and kidney length and a decline in glomerular filtration rate (GFR). This study evaluated a possible correlation between renal function and kidney size measured by ultrasonography (US), and whether the latter helps estimate GFR in the elderly. METHODS: Twenty-five medically stable elderly patients (mean age 85 +/- 5 yrs) were examined in a geriatric ward at a university hospital. Blood samples were taken to determine serum creatinine (Cr) levels. On the same day, 51chromium ethylenediamine tetraacetic acid (51Cr-EDTA) clearance was performed as the gold standard of GFR. US measured kidney length, transverse and anteroposterior dimensions. RESULTS: Serum Cr (r=-0.67; p=0.0002), Cockcroft-Gault formula (r=0.82; p<0.0001), absolute length (r=0.51; p=0.008) and volume kidney (r=0.46; p=0.02) correlated significantly with GFR. After receiver operating curve (ROC) analysis, length was less specific than sensitive in detecting renal impairment. Adding length to the Cockcroft-Gault formula did not improve GFR estimation (p=0.44). In contrast, adding length to serum Cr levels improved GFR estimation (p=0.015). CONCLUSION: In the elderly, kidney length and volume significantly correlated with GFR. However, length has a low specificity in predicting renal impairment. Therefore, in clinical practice, serum Cr levels and calculated Cr clearance are more useful in predicting renal impairment. However, normal kidney length can help to exclude renal impairment in the elderly at risk of GFR underestimation by a calculated Cr clearance.
