COVID-19 is not over and age is not enough: Using frailty for prognostication in hospitalized patients.

BACKGROUND: Frailty screening using the Clinical Frailty Scale (CFS) has been proposed to guide resource allocation in acute care settings during the pandemic. However, the association between frailty and coronavirus disease 2019 (COVID-19) prognosis remains unclear. OBJECTIVES: To investigate the association between frailty and mortality over 6 months in middle-aged and older patients hospitalized with COVID-19 and the association between acute morbidity severity and mortality across frailty strata. DESIGN: Observational cohort study. SETTING: Large academic medical center in Brazil. PARTICIPANTS: A total of 1830 patients aged ≥50 years hospitalized with COVID-19 (March-July 2020). MEASUREMENTS: We screened baseline frailty using the CFS (1-9) and classified patients as fit to managing well (1-3), vulnerable (4), mildly (5), moderately (6), or severely frail to terminally ill (7-9). We also computed a frailty index (0-1; frail >0.25), a well-known frailty measure. We used Cox proportional hazards models to estimate the association between frailty and time to death within 30 days and 6 months of admission. We also examined whether frailty identified different mortality risk levels within strata of similar age and acute morbidity as measured by the Sequential Organ Failure Assessment (SOFA) score. RESULTS: Median age was 66 years, 58% were male, and 27% were frail to some degree. Compared with fit-to-managing-well patients, the adjusted hazard ratios (95% confidence interval [CI]) for 30-day and 6-month mortality were, respectively, 1.4 (1.1-1.7) and 1.4 (1.1-1.7) for vulnerable patients; 1.5 (1.1-1.9) and 1.5 (1.1-1.8) for mild frailty; 1.8 (1.4-2.3) and 1.9 (1.5-2.4) for moderate frailty; and 2.1 (1.6-2.7) and 2.3 (1.8-2.9) for severe frailty to terminally ill. The CFS achieved outstanding accuracy to identify frailty compared with the Frailty Index (area under the curve = 0.94; 95% CI = 0.93-0.95) and predicted different mortality risks within age and acute morbidity groups. CONCLUSIONS: Our results encourage the use of frailty, alongside measures of acute morbidity, to guide clinicians in prognostication and resource allocation in hospitalized patients with COVID-19.

Prospective GERiatric Observational (ProGERO) study: cohort design and preliminary results.

BACKGROUND: The demographic changes in Brazil as a result of population aging is one of the fastest in the world. The far-reaching new challenges that come with a large older population are particularly disquieting in low- and middle-income countries (LMICs). Longitudinal studies must be completed in LMICs to investigate the social and biological determinants of aging and the consequences of such demographic changes in their context. Therefore, we designed the Prospective GERiatric Observational (ProGERO) study, a longitudinal study of outpatient older adults in São Paulo, Brazil, to collect data both on aging and chronic diseases, and investigate characteristics associated with adverse outcomes in this population. METHODS: The ProGERO study takes place in a geriatric outpatient clinic in the largest academic medical center in Latin America. We performed baseline health examinations in 2017 and will complete subsequent in-person visits every 3 years when new participants will also be recruited. We will use periodic telephone interviews to collect information on the outcomes of interest between in-person visits. The baseline evaluation included data on demographics, medical history, physical examination, and comprehensive geriatric assessment (CGA; including multimorbidity, medications, social support, functional status, cognition, depressive symptoms, nutritional status, pain assessment, frailty, gait speed, handgrip strength, and chair-stands test). We used a previously validated CGA-based model to rank participants according to mortality risk (low, medium, high). Our selected outcomes were falls, disability, health services utilization (emergency room visits and hospital admissions), institutionalization, and death. We will follow participants for at least 10 years. RESULTS: We included 1336 participants with a mean age of 82 ± 8 years old. Overall, 70% were women, 31% were frail, and 43% had a Charlson comorbidity index score ≥ 3. According to our CGA-based model, the incidence of death in 1 year varied significantly across categories (low-risk = 0.6%; medium-risk = 7.4%; high-risk = 17.5%; P < 0.001). CONCLUSION: The ProGERO study will provide detailed clinical data and explore the late-life trajectories of outpatient older patients during a follow-up period of at least 10 years. Moreover, the study will substantially contribute to new information on the predictors of aging, senescence, and senility, particularly in frail and pre-frail outpatients from an LMIC city.

Teaching geriatrics during the COVID-19 pandemic: experience of a brazilian medical school / Ensino de Geriatria durante a Pandemia de COVID-19: Experiência de uma Faculdade de Medicina Brasileira

INTRODUCTION: During the COVID-19 pandemic, the discipline of geriatrics at the Santa Casa de Sao Paulo School of Medical Sciences of São Paulo was adapted to a web-based learning environment due to social distancing measures. OBJECTIVE: To describe the full adaptation of the discipline of geriatrics to a web-based learning tool, of two activities that were developed including the current COVID-19 to illustrate some of the main concepts of geriatric medicine. METHODS: The course was fully adapted to the open-source course management system called MOODLE. The first activity was a COVID-19 clinical case discussion, whose main objective was to include COVID-19 in the content of our course, illustrating some of the main concepts of geriatrics. The second activity was a Comprehensive Geriatric Assessment (CGA) experience, done via videoconference, which also assessed the impact of social distancing measures on the health of older adults. RESULTS: A total of 43 medical students performed both activities, and 95% of the students considered the inclusion of the COVID-19 into the discipline of geriatrics useful, 88% approved the practical experience of CGA, and 84% felt that they contributed to the health of the interviewees after contact. CONCLUSION: Adapting our discipline to a web-based learning tool, while including the current COVID-19 in our course content and a practical experience of CGA via videoconference was possible and approved by students. The adoption of this initiative may not only be an academic strategy, but also a possible way to improve the quality of life of older people during the COVID-19 pandemic

Persistent pain and cognitive decline in older adults: a systematic review and meta-analysis from longitudinal studies.

Both persistent pain and cognitive decline prevalence increase with advancing age and are associated with functional decline. However, the association of pain and cognitive decline has not been evaluated yet by a systematic assessment of longitudinal studies. We aimed to assess the association of persistent pain as a risk factor for cognitive decline in community older adults, using data from longitudinal studies in a systematic review and meta-analysis. Publications were identified using a systematic search on PubMed, EMBASE, and Cochrane Library databases from inception to June 2019. Because heterogeneity across studies was high, we used random-effects meta-analysis to calculate the pooled relative risk (RR) for the association between persistent pain and cognitive decline incidence. We investigated sources of heterogeneity among studies using meta-regression and stratified analyses. We included 10 prospective longitudinal studies with 57,495 participants with a mean age at the baseline ranging from 61.8 to 88.4 years and mean follow-up times ranging from 2.75 to 11.8 years. Persistent pain at baseline was not associated with the development of cognitive decline during the follow-up (pooled RR = 1.05, 95% confidence interval = 0.92-1.21). In sensitivity analyses, only length of follow-up time ≤4.5 years was associated with a higher risk of cognitive impairment (pooled RR = 1.19, 95% confidence interval = 1.10-1.28). Persistent pain was not associated with the incidence of cognitive decline.

AMPI-AB validity and reliability: a multidimensional tool in resource-limited primary care settings.

BACKGROUND: The early identification of individuals at high risk for adverse outcomes by a Comprehensive Geriatric Assessment (CGA) in resource-limited primary care settings enables tailored treatments, however, the evidence concerning its benefits are still controversial. The main objective of this study was to examine the validity and reliability of the "Multidimensional Assessment of Older People in Primary Care (AMPI-AB)", a CGA for primary care in resource-limited settings. METHODS: Longitudinal study, with median follow-up time of 16 months. Older adults from a public primary care unit in São Paulo, Brazil, were consecutively admitted. Reliability was tested in a sample from a public geriatric outpatient clinic. Participants were classified by the AMPI-AB score as requiring a low, intermediate or high complexity of care. The Physical Frailty Phenotype was used to explore the AMPI-AB's concurrent validity. Predictive validity was assessed with mortality, worsening of the functional status, hospitalizations, emergency room (ER) visits and falls. The area under the ROC curve and logistic regression were calculated for binary outcomes, and a Cox proportional hazards model was used for survival analysis. RESULTS: Older adults (n = 317) with a median age of 80 (74-86) years, 67% female, were consecutively admitted. At the follow-up, 7.1% of participants had died, and increased dependency on basic and instrumental activities of daily living was detected in 8.9 and 41.1% of the participants, respectively. The AMPI-AB score was accurate in detecting frailty (area under the ROC curve = 0.851), predicted mortality (HR = 1.25, 95%CI = 1.13-1.39) and increased dependency on basic (OR = 1.26, 95%CI = 1.10-1.46) and instrumental (OR = 1.22, 95%CI = 1.12-1.34) activities of daily living, hospitalizations (OR = 2.05, 95%CI = 1.04-1.26), ER visits (OR = 1.20, 95%CI = 1.10-1.31) and falls (OR = 1.10, 95%CI = 1.01-1.20), all models adjusted for sex and years of schooling. Reliability was tested in a sample of 52 older adults with a median age of 72 (85-64) years, 63.5% female. The AMPI-AB also had good interrater (ICC = 0.87, 95%CI = 0.78-0.92), test-retest (ICC = 0.86, 95%CI = 0.76-0.93) and proxy reliability (ICC = 0.84, 95%CI = 0.67-0.93). The Cronbach's alpha was 0.69, and the mean AMPI-AB administration time was 05:44 ± 02:42 min. CONCLUSION: The AMPI-AB is a valid and reliable tool for managing older adults in resource-limited primary care settings.

Nasopharyngeal carriage of Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus in a Brazilian elderly cohort.

We aimed to investigate the nasopharyngeal colonization (NPC) by Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus in the elderly population and to assess the demographic factors associated with NPC. This was an observational cohort study in which outpatients aged ≥60 years were enrolled from April to August 2017, with a follow-up visit from September through December 2017. Nasopharyngeal (NP) swabs were collected, bacteria were detected and isolated, and isolates were subjected to phenotypic and molecular characterization using standard microbiological techniques. At enrolment, the rates of S. aureus, methicillin-resistant S. aureus (MRSA), H. influenzae, and S. pneumoniae among 776 elderly outpatients were 15.9%, 2.3%, 2.5%, and 2.2%, respectively. Toxin production was detected in 21.1% of methicillin-susceptible S. aureus, and three SCCmec types were identified: II/IIb, IVa, and VI. At the follow-up visit, all carriage rates were similar (p > 0.05) to the rates at enrolment. Most of S. pneumoniae serotypes were not included in pneumococcal conjugate vaccines (PCVs), except for 7F, 3, and 19A. All strains of H. influenzae were non-typeable. Previous use of antibiotics and 23-valent pneumococcal polysaccharide vaccination (p < 0.05) were risk factors for S. aureus and MRSA carriage; S. aureus colonization was also associated with chronic kidney disease (p = 0.021). S. pneumoniae carriage was associated with male gender (p = 0.032) and an absence of diabetes (p = 0.034), while not receiving an influenza vaccine (p = 0.049) and chronic obstructive pulmonary disease (p = 0.031) were risk factors for H. influenzae colonization. The frailty of study participants was not associated with colonization status. We found a higher S. aureus carriage rate compared with the S. pneumoniae- and H. influenzae-carriage rates in a well-attended population in a geriatric outpatient clinic. This is one of the few studies conducted in Brazil that can support future colonization studies among elderly individuals.

Persistent pain is a risk factor for frailty: a systematic review and meta-analysis from prospective longitudinal studies.

Background: pain is prevalent in frail older adults; however, the association of pain and frailty has not been evaluated yet by a systematic assessment of prospective longitudinal studies. Objective: we aimed to assess the association of persistent pain as a risk factor for frailty incidence, using data from longitudinal studies in a systematic review and meta-analysis. Methods: publications were identified using a systematic search on PubMed, Embase, Cochrane Library and clinicaltrials.gov databases from inception to October 2017. Since heterogeneity across studies was high, we used random-effects meta-analysis to calculate the pooled relative risk for the association between persistent pain and the incidence of frailty. We investigated sources of heterogeneity among studies using meta-regression and stratified analyses. Results: we included five prospective longitudinal studies with 13,120 participants (46% women, mean age from 59 to 85 years old). Participants with persistent pain at baseline had twice the risk of developing frailty during the follow-up (pooled RR = 2.22, 95% CI = 1.14-4.29). No variables were related to study heterogeneity in sensitivity analyses. Conclusion: persistent pain was a risk factor for the development of frailty in a meta-analysis of longitudinal studies. Better understanding of the association between pain and frailty with proper evaluation of potential confounders could allow the development of targeted interventions.

Functional Status is a Predictor of Postoperative Complications After Cancer Surgery in the Very Old.

BACKGROUND: The association between preoperative functional status and postoperative complications after cancer surgery is very well described in the 'youngest old' population; however, limited information is available for the very old (i.e. those aged 80 years and older). OBJECTIVE: Our aim was to evaluate whether functional status, expressed as metabolic equivalents (METs), is a predictor of adverse postoperative outcomes in very old patients. METHODS: In a retrospective cohort study, we included all patients aged 80 years or older who underwent elective oncological surgery at a tertiary hospital in Brazil in 2011. The primary outcome was postoperative complications up to 30 days after surgery. Functional status was evaluated using a simple questionnaire, which classified participants into three groups based on METs. We used logistic regression models to investigate the association between functional status and the occurrence of complications, adjusted for possible confounders. RESULTS: We analyzed data from 138 patients aged 80 years or older. The mean age of the sample was 84.2 ± 4.2 years and 52% were female; 65% of the procedures were classified as low risk and 35% were classified as intermediate risk. Regarding functional status, 72% of the sample had a performance equivalent to fewer than 4 METs, 27% had 4-6 METs, and 1% had more than 6 METs. Postoperative complications were observed in 25%, and the mortality rate was 2%. Better functional status was associated with reduced odds of postoperative complications in multivariate analysis (odds ratio 0.11, 95% confidence interval 0.02-0.85; p = 0.034). CONCLUSION: Functional status seems to be related to surgical morbidity in the very old.

The geriatrician's perspective on practical aspects of the multidisciplinary care of older adults with cancer.

Multidisciplinary teams (MDTs) have been incorporated into the practical care of elderly patients with cancer. Several geriatric oncology centres have attempted to determine the best way to implement MDTs by using geriatric assessment (GA). Developing a geriatric oncology service is a feasible work, which requires significant resources. The challenges of MDTs must be known so that better care planning for elderly patients with cancer can be devised. The aim of this paper is to discuss the practical aspects of the multidisciplinary care of older adults with cancer by considering a geriatric point of view and the recent literature. Reviewing data from recent studies helps enumerate the major challenges in establishing collaboration in geriatric oncology: evaluating the resources of your centre, knowing the role of each member of the team, establishing good communication both within the team and with the patients, and determining referral criteria and using screening tests to select which patients can benefit the most from the multidisciplinary evaluation and a more thorough GA.
