Assessment of the Appropriateness of Prescriptions in a Geriatric Outpatient Clinic

Objectives: Appropriateness of the geriatric outpatients' medications needs special attention due to risks of falls, fractures, depression, hospital admissions and mortality. This study aimed to identify current practice on medication usage by using the 2nd version of "Screening Tool of Older People's Potentially Inappropriate Prescriptions" and "Screening Tool to Alert Doctors to Right Treatment" criteria and affecting factors for the Turkish population. Materials and Methods: This cross-sectional study was conducted between September 2015 and May 2016 at a university research and training hospital's geriatric outpatient clinic. Patients aged ≥65 years and had ≥5 different prescribed medications (considered as polypharmacy) were recruited. The main outcome measure was the frequency of inappropriate medications identified by clinical pharmacist in the outpatient clinic according to the 2nd version of the criterion sets. Results: A total of 700 patients (440 female) were included in this study. According to the results, 316 patients (45.1%) with at least one potentially inappropriate medication and 668 patients (98.3%) with at least one potential prescription omission were detected. Potentially inappropriate medications were associated with the number of medications used per patient [odds ratio (OR): 1.20 p<0.001], living alone (OR: 4.12 p=0.02), and having congestive heart failure (OR: 2.41 p<0.001). Twenty-two (27.5%) out of 80 criteria and 4 (11.8%) out of 34 criteria did not apply to the study population. Conclusion: Detecting inappropriate medications to maintain treatment effectiveness is necessary to provide the optimum therapy. Despite the awareness of polypharmacy in outpatient clinics it is still one of the important causes of inappropriate prescription followed by vaccination rate. Therefore, with the contribution of clinical pharmacist using these available criteria is important, moreover modification of these criteria according to the local needs to be considered to achieve better outcomes.

Thiol-disulfide homeostasis and ischemia-modified albumin as a marker of oxidative stress in patients with sarcopenia.

AIM: Sarcopenia is characterized by progressive and generalized loss of skeletal muscle mass and strength. Chronic inflammatory conditions and increased oxidative stress are in the pathogenesis of sarcopenia. Our aim was to evaluate the relationship between sarcopenia and thiol-disulfide homeostasis and ischemia-modified albumin levels as an oxidative stress marker. METHODS: Patients aged ≥65 years were recruited in this study. Sarcopenia was diagnosed according to the European Working Group on Sarcopenia in Older People criterion. Total thiol, native thiol, disulfide and ischemia-modified albumin levels were measures according to clinical and laboratory features. Patients were divided into two groups according to their sarcopenia presence; thiol-disulfide homeostasis and ischemia-modified albumin levels were evaluated between these groups. RESULTS: Overall, 94 patients were analyzed. The mean age was 75.0 ± 6.71 years. A total of 39% of the patients were diagnosed as probable sarcopenia, 3.2% had sarcopenia, 6.4% had severe sarcopenia and 51.1% were diagnosed as normal. The levels of native thiol, total thiol, disulfide level and disulfide-native thiol, native thiol-total thiol and disulfide-total thiol ratios were similar in patients with sarcopenia when compared with the control group. In addition, there were no differences between albumin and ischemia-modified albumin levels. In univariate regression analysis, handgrip strength was found to be an independent predictor of native thiol and total thiol, and disulfide levels. CONCLUSION: This is the first study in the literature that evaluates the thiol-disulfide homeostasis and ischemia-modified albumin levels in sarcopenic older patients. Long-term studies are warranted to confirm the relationship between oxidative stress markers and sarcopenia. Geriatr Gerontol Int 2021; 21: 584-589.

Association of physical frailty with cognitive function and mood in older adults without dementia and depression

Background/aim: Physical frailty is thought to be related with a decline in cognitive function, mood, and social activities, especially in patients with depression and dementia. It is not clear whether or not physical frailty is associated with an impairment in cognitive function and mood in patients without dementia and depression. In this study, we evaluated the association of physical frailty with cognitive function and mood in geriatric patients without dementia and depression. Material and methods: In this study, 612 patients aged 65 years and over were evaluated. Physical frailty was assessed by using Fried criteria. Furthermore, comprehensive geriatric assessment was performed to each patient. Results: Median age of the patients was 72 years (min-max: 65­93), 58% were female, and 6.5% were frail. Clock drawing (p < 0.001), MMSE (p < 0.001), and Yesevage geriatric depression scale (p: 0.010) test results were worse in frail patients compared to pre-frail and robust ones. Age (p: 0.009), being university graduate (p: 0.031), three words recall test (p: 0.014), activities of daily living (ADL) (p: 0.006), instrumental activities of daily living (IADL) (p < 0.001), and MNA-SF (p: 0.001) scores were determined to be independent related factors of frailty. Conclusion: We have demonstrated that cognitive function and mood might be associated with physical frailty in patients without dementia and depression.

Ultrasonography versus bioelectrical impedance analysis: which predicts muscle strength better?

Background & Aim: Muscle strength seems to be more relevant to the functionality than muscle mass in sarcopenia. Different diagnostic techniques are available for the evaluation of muscle mass. Ultrasonography (USG) seems to have some advantages compared to other techniques especially bioelectrical impedance analysis (BIA) including being not affected of the results by the factors like extreme body mass indexes (BMI) or hypervolemia. The aim of the study is to determine and compare the muscle strength prediction value of muscle mass measured by using USG or BIA and determine the cut-off values for the Turkish population.Methods: One hundred and thirty six patients admitted to geriatrics outpatient clinic for comprehensive geriatric assessment were included in the study. Body composition was determined by BIA and skeletal muscle mass index (SMI) was measured. Thickness of the gastrocnemius muscle was measured via USG. Diagnosis of sarcopenia was made according to the EWSGOP 2 diagnostic criteria.Results: The best cut-off value for gastrocnemius muscle thickness to predict low HGS was ≤13.8 mm (AUC:0.690,p <0.001). SMI was not found to predict low HGS (AUC:0.573,p >0.05). Comparison of AUCs for gastrocnemius muscle thickness and SMI showed that gastrocnemius muscle thickness had higher AUC (p=0.008). For predicting sarcopenia, the best cut-off value of gastrocnemius muscle thickness was found to be ≤12.3 mm in women (AUC: 0.862,p <0.001) and ≤12.3 mm in men (AUC:0.900, p < 0.001).Conclusions: In this study, we found that gastrocnemius thickness measured by USG seems to predict low HGS better than SMI measured by BIA.

Frailty is associated with poor sleep quality in the oldest old

Background/aim: Sleep disorders and frailty increase with advancing age, along with physical disabilities, cognitive dysfunction, mood disorders, and social vulnerability. Thus, the study objective was to evaluate the relationship between frailty and sleep quality in the oldest old patients. Materials and methods: In this study, 100 patients aged ≥80 years were assessed using comprehensive geriatric assessment (CGA) including basic activities of daily living (ADL), instrumental ADL, handgrip strength, the Geriatric Depression Scale-15, the Mini- Mental State Examination, and the Mini-Nutritional Assessment-Short Form. The sleep quality and frailty status of the patients were evaluated using the Pittsburgh Sleep Quality Index (PSQI) and the Fried Frailty Index, respectively. Results: The median age of the participants was 84 years (80­92), 55% of them were women, and 41% of them were frail. There was no statistically significant difference between the frail and nonfrail groups in terms of age, sex, and comorbidities (P > 0.050). The frail patients scored poorly according to the CGA tests when compared to the nonfrail ones (P < 0.050). The median score for the PSQI was significantly higher in the frail group, 12 points (3­19) versus 6 points (1­19) in the nonfrail patients (P < 0.001). The PSQI score (odds ratio [OR] of 1.308, 95% confidence interval [CI]: 1.092­1.566, P = 0.004), female sex (OR of 5.489, 95% CI: 1.063­28.337; P = 0.042), and the basic ADL score (OR of 0.383; 95% CI: 0.207­0.706; P = 0.002) were found to be independently associated with frailty using multivariate analysis. Conclusion: Sleep quality was significantly decreased in the oldest old frail patients compared to the nonfrail ones, and poor sleep quality was independently associated with frailty. Evaluating the sleep patterns of the oldest old patients with CGA in daily geriatric practice might help to improve the quality of life of frail patients.

Validity and reliability of the G8 screening test in older non-cancer patients.

PURPOSE: A comprehensive geriatric assessment (CGA) is a time-consuming approach that requires a special team and a screening test, whereas the G8 screening test is a practical and validated test for screening cancer patients. This study aimed to evaluate the validity and reliability of the G8 test in older patients without cancer and to investigate its concordance with CGA in an outpatient clinic. METHODS: Two hundred older patients were included in the study. CGA and G8 tests were performed, and the concordance between them was evaluated for scale validity using Spearman correlation coefficients (r) and kappa analyses. Patients who obtained scores lower than the predefined cutoff values in at least one of the CGA tests were considered to have an abnormal CGA. Inter-rater and intra-rater concordance were assessed for reliability. RESULTS: Of the 200 patients, 57.4% were female, and the median age was 73 (63-93) years. There was a strong concordance between the CGA and G8 screening test (kappa: 0.630; p < 0.001). Inter-rater and intra-rater concordance in the reliability assessments were high (kappa: 0.886; kappa: 875; p < 0.001, respectively), and inter- and intra-clinician assessments of the G8 scores revealed significant correlations (r = 0.962 and r = 0.976, respectively; p < 0.001). CONCLUSION: The G8 screening test is a valid and reliable tool for older adults without malignancy. It is a quick and practical test for physicians who frequently admit older patients.

Relationship between psychological pain and death anxiety with comprehensive geriatric assessment in older adults.

AIM: Psychological pain refers to the torment that results from adverse experiences, such as loneliness, guilt, frustration, hopelessness or loss. Psychological pain may impair physical and psychosocial functioning of older adults. Death anxiety is associated with cognitive function deterioration, change to social environment and increased risk of depression. This study investigated associations among components of comprehensive geriatric assessment (CGA), death anxiety and psychological pain. METHODS: In total, 100 patients aged ≥65 years were included in this study. Demographic characteristics and CGA test scores were examined. The Templer scale was used to evaluate death anxiety; the Psychache scale was used to evaluate psychological pain. Multivariate logistic regression analysis was performed to identify parameters independently associated with poor cognitive performance and death anxiety. RESULTS: The patients' median age was 73 (65-92) years. Death anxiety was detected in 34% of patients. Psychological pain and death anxiety levels were significantly associated with Mini-Mental State Examination, clock drawing test, Geriatric Depression Scale-15 and Instrumental Activities of Daily Living (IADL) scores. Psychological pain levels were independently associated with cognitive performance. Finally, psychological pain and IADL scores were independently associated with death anxiety. CONCLUSIONS: During a CGA, practitioners should note that psychological pain and death anxiety may negatively affect cognitive function and IADL scores. Patients should be re-evaluated, following suitable psychotherapeutic interventions. Geriatr Gerontol Int 2020; 20: 1056-1060..

The relation between body fluid composition and echocardiographic tissue Doppler measurements in patients with end-stage renal disease.

AIM: The relationship between body fluid composition measurements and echocardiographic tissue Doppler measurements before and after hemodialysis (HD) in end-stage renal disease is investigated. MATERIALS AND METHODS: BCM (BCM-Fresenius Medical Care) Body Composition Monitor was used to measure the fluid status and body composition of patients by BIA method. TDE was performed before and after HD and the measurements were recorded. RESULTS: The mean age of the 72 patients was 53.7 ± 17.2 years. There was a significant decrease in over hydration (OH) status, total body fluid (TBW), extracellular body fluid (ECW), intracellular body fluid (ICW), ECW/ICW ratio in patients after HD (p < 0.001, p0.001, p0.001, p0,001). A significant decrease in lateral, septal and tricuspid E' measurements and in E'/A' ratio was seen after HD (p: 0.012, p: 0.001, p < 0.001, p: 0.002, p0.001, p0,001). There was a significant difference in A' measurements from septal annulus in patients before and after HD (p: 0.001). A significant increase was observed in isovolemic contraction volume (IVCV) measurements from lateral, septal and tricuspid annulus in patients after HD (p < 0.001, p0.001, p: 0.012). A correlation was determined between the differences of lateral and tricuspid valve E' in patients before and after HD and the differences of ECW in patients before and after HD (p: 0.007 r: 0.401, p: 0.017 r: 0.358). CONCLUSION: In this study; a correlation was determined between the acute decrease in OH amount and alteration in echocardiographic tissue Doppler parameters in patients after HD.

Impact of atrial fibrillation on frailty and functionality in older adults.

BACKGROUND AND AIM: Atrial fibrillation (AF), the most common sustained arrhythmia in older adults, causes significant complications such as stroke, dementia, and decreased quality of life. Frailty is a geriatric syndrome that is associated with increased risk of poor clinical outcomes including falls, disability, and mortality. We aimed to investigate the relationship between AF and frailty and functionality in older adults. METHODS: A total of 123 patients 64 with AF and 59 with normal sinus rhythm were enrolled in the study with cross-sectional design. All patients underwent comprehensive geriatric assessment (CGA). Frailty status was assessed using Fried criteria and FRAIL scale. The brief Older People's Quality of Life questionnaire was applied for quality of life. Results of the laboratory tests were recorded and compared for both groups. RESULTS: Although the frequency of frailty status determined by the Fried criteria and the FRAIL scale was higher in the AF group, this difference was not statistically significant. However, it was found that there was a positive correlation between the European Heart Rhythm Association (EHRA) AF symptom score and frailty according to the FRAIL scale (Goodman and Kruskal gamma coefficient = 0.39, p = 0.020). Comorbidities and polypharmacy were more common in the AF group (p < 0.001, both). CGA revealed lower Lawton-Brody Instrumental Activities of Daily Living scores (p = 0.024), higher fall rates in the previous year (p = 0.016), and slower walking speed (p = 0.020) in the AF group. Total cholesterol, LDL, HDL, total protein, albumin, and prealbumin were lower; brain natriuretic peptide (BNP) and C-reactive protein (CRP) levels were higher in the AF group. CONCLUSIONS: EHRA AF symptom severity score is positively correlated with frailty. AF is associated with worse metabolic profile and clinical features on CGA that AF might be a frailty marker. Frailty should be investigated in AF patients.

Masked hypertension is associated with end organ damage in geriatric age: Geriatric MASked Hypertension and End organ damage (G-MASH-End organ Study).

Purpose: It is a question whether masked hypertension (MH) leads to end-organ damage in the geriatric age group. The aim of this study is to evaluate the associations between MH and end-organ damage such as left ventricular hypertrophy (LVH) and proteinuria in geriatric population.Materials and methods: One hundred and two patients who were admitted to the outpatient clinic were included in the study. These patients were also included in the GMASH-Cog study in 2016, which examined the relationship between MH and cognitive function. All patients underwent ambulatory blood pressure measurement procedures. Cardiac functions of all patients were determined by echocardiography. Spot urine albumin/creatinine ratio (ACR) was measured in all patients.Results: Forty four of 102 patients (43%) were diagnosed with MH. ACR was 9.61 mg/gr in the MH group and 7.12 mg/gr in the normal group (p = .021). In addition, left ventricular mass index (LVMI) was found to be higher in the MH group than in the normal group. Mean LVMI scores were 107.76 ± 16.37 in patients with MH and 100.39 ± 19.32 in the normotensive group (p = .046).Conclusion: MH is associated with end-organ damage in geriatric patients. Urinary albumin excretion and LVH which are the parameters of end-organ damage were significantly higher in MH patients. MH may cause end-organ damage and should not be overlooked in geriatric patients.

An important problem in an aging country: identifying the frailty via 9 Point Clinical Frailty Scale.

OBJECTIVES: Frailty is a geriatric syndrome which develops as a result of cumulative decline in many physiological systems and results in an increased vulnerability and risk of adverse outcomes. The Clinical Frailty Scale (CFS) was validated as a predictor of adverse outcomes in community-dwelling older people and evaluates items such as comorbidity, cognitive impairment and disability. We aimed to study the concurrent and construct validity and reliability of the 9 point CFS in Turkish Population.Methods: This study was designed as a cross-sectional study. Participants, who were admitted to a geriatric medicine outpatient clinic, were included. Validity of 9 point CFS was tested by its correlation with the assessment and opinion of an experienced geriatric medicine specialist and Fried frailty phenotype. Test-retest and inter-rater reliability analyses were also performed.Results: Median age of the 118 patients was 74.5 years (min: 65 max: 88) and 64.4 % were female. The concordance of CFS and experienced geriatric medicine specialist's opinion was excellent (Cohen's K: 0.80, p < 0.001).The concordance of CFS and Fried Frailty phenotype was moderate (Cohen's K: 0.514, p < 0.001).CFS inter-rater reliability and test-retest reliability was very strong (Cohen's K: 0.811, p < 0.001 and Cohen's K: 1.0, p < 0.001, respectively).Conclusions: CFS appears to be a quick, reliable and valid frailty screening tool for community-dwelling older adults in the Turkish population.

Timing of Dysphagia Screening in Alzheimer's Dementia.

BACKGROUND: Dysphagia is an important and frequent symptom in Alzheimer's dementia (AD). We hypothesized that dysphagia could be seen in the early stages of AD and sarcopenia presence rather than the severity of the AD affecting dysphagia. The main aim of this study was to investigate swallowing functions in AD patients according to stages. The second aim was to investigate the correlation between sarcopenia and dysphagia in AD. METHODS: This study involved 76 probable AD patients. For all participants, diagnosis of sarcopenia was based on definitions from the revised version of European Working Group on Sarcopenia in Older People at 2018. Dysphagia symptom severity was evaluated by the Turkish version of the Eating Assessment Tool, a videofluoroscopic swallowing study (VFSS) was performed for instrumental evaluation of swallowing. The patients were divided into 3 groups according to the clinical dementia rating (CDR) scale as CDR 1 (mild dementia), CDR 2 (moderate dementia), and CDR 3 (severe dementia). Swallowing evaluation parameters were analyzed between these groups. RESULTS: Mean age was 78.9 ± 6.4 years, and 56.4% were female. Twenty-six patients had mild dementia, 31 patients had moderate dementia, 19 patients had severe dementia (CDR 3). We found that sarcopenia rates were similar between AD stages according to CDR in our study population and dysphagia could be seen in every stage of AD. In a multivariate analysis, polypharmacy and sarcopenia were found to be independently associated factors for dysphagia, irrespective of stage of AD (OR: 6.1, CI: 1.57-23.9, P = 0.009; OR: 4.9, CI: 1.24-19.6, P = 0.023, respectively). CONCLUSION: Aspirations may be subtle so that AD patients and caregivers may not be aware of swallowing difficulties. Therefore, all AD patients, especially those who have polypharmacy and/or sarcopenia (probable-sarcopenia-severe sarcopenia), should be screened for dysphagia in every stage.

Masked Hypertension is Associated With Cognitive Decline in Geriatric Age-Geriatric MASked Hypertension and Cognition (G-MASH-cog) Study.

Background: Masked hypertension is described as high ambulatory blood pressure measurements (ABPM) where office blood pressure measurements are normal. Effect of hypertension on cognitive functions is well known. However, the effect of masked hypertension on cognitive functions is unclear. The aim of this study is to examine the relationship between masked hypertension and cognitive functions. Methods: One hundred-two normotensive patients admitted to the Geriatric Medicine outpatient clinic were included. Exclusion criteria were hypertension, dementia, major depression, and usage of antihypertensive medication. All patients underwent ABPM procedures and average daytime blood pressure, mean blood pressure at night and the 24-hour average blood pressure measurements were recorded. Comprehensive geriatric assessment tests and neuropsychological tests were administered. The diagnosis of masked hypertension was based on the definitions in the 2013 guideline of the European Society of Cardiology. Results: Forty-four patients (43%) were diagnosed with masked hypertension. Patients with masked hypertension had significantly lower scores on Mini-Mental State Examination (MMSE) test, Quick Mild Cognitive Impairment Test (QMCI), and Categorical Fluency Test than the normotensive patients (p = .011; p = .046; and p = .004; respectively). Montreal Cognitive Assessment Scale test score was lower in masked hypertension, although this was not statistically significant. Conclusion: This study may indicate that geriatric patients with masked hypertension, compared to normotensive patients have decreased cognitive functions. Masked hypertension should be kept in mind while assessing older adults. When masked hypertension is detected, cognitive assessment is essential to diagnose possible cognitive dysfunction at early stage.
