RESUMO

BACKGROUND: medication safety is a major public health challenge, particularly among older populations. Changing the medication's form may be inappropriate and may incur a risk of adverse effects. OBJECTIVES: the objectives were to estimate the prevalence of medication modification and to identify factors associated with the practice of medication modification in community-dwelling older individuals. DESIGN: observational, cross-sectional, single-centre and epidemiological study. SETTINGS: community. SUBJECTS: outpatients and/or their accompanying persons, aged 65 years or over. METHODS: sociodemographic and clinical variables were recorded. It was also noted how the medication was taken, who administered the medications, the number of oral medications ingested per day, and whether or not the form of the medication was modified to facilitate administration. Descriptive analyses and logistic regression were performed. RESULTS: a total of 252 individuals were included in the study, with a mean age of 83 ± 7 years. Of these, 44 (17.5%) reported modifying their medication, either routinely (n = 36) or occasionally (n = 8). The factors independently associated with medication modification were the existence of psycho-behavioural disorders [odds ratio (OR) = 3.78; 95% confidence interval (CI) = 1.84-7.76; P < 0.0001], mobility difficulties (OR = 2.16; 95% CI = 1.01-4.62; P = 0.04), and the presence of dysphagia (OR = 3.23; 95% CI = 1.49-6.99; P < 0.0001). CONCLUSIONS: this study indicates that main caregivers are more likely to engage in medication modification than nurses or the patients themselves. Factors associated with medication modification include swallowing difficulties and psycho-behavioural disorders. These findings provide new avenues that could help to mitigate this practice.

RESUMO

OBJECTIVE: To investigate whether the long-term survival in elderly patients with prior Chikungunya virus infection (CVI) is associated with the clinical form presented in the acute phase, as defined by the WHO classification. METHODS: Retrospective cohort study performed in Martinique University Hospitals. Patients who attended the emergency department for suspected CVI, and who had a positive biological diagnosis of CVI by reverse transcription-polymerase chain reaction on a plasma sample between 10 January and 31 December 2014 were eligible for inclusion. Time-to-death was the primary outcome. The independent relationship between clinical forms and time-to-death was analysed using a Cox model. RESULTS: In total, 268 patients were included. Mean age was 80 ± 8 years, 53% were women. Median length of follow-up was 28 months (range: 0-39). During follow-up, 53 (19.8%) patients died. Median survival time was 13.2 months (range: 0-33.6). At the end of follow-up, death rates were 4.6% for acute clinical cases, 19.0% for atypical cases, 19.2% for severe acute cases and 23.5% for unclassifiable cases. By multivariable analysis, the clinical form of CVI at admission was found to be independently associated with long-term survival (atypical form: HR = 2.38; 95% CI = 2.15-2.62; severe acute form: HR = 2.40; 95% CI = 2.17-2.64; unclassifiable form: HR = 2.28; 95% CI = 2.06-2.51). CONCLUSION: The clinical form at presentation with CVI has a significant impact on long-term survival. Management of CVI patients should be tailored according to their clinical form at admission.


OBJECTIF: Etudier si la survie à long terme chez les patients âgés avec une infection antérieure par le virus du chikungunya (IVC) est associée à la forme clinique présente dans la phase aiguë, telle que définie par la classification de l'OMS. MÉTHODES: Etude de cohorte rétrospective réalisée dans les hôpitaux universitaires de la Martinique. Les patients qui se présentaient au service des urgences en cas de suspicion d'IVC et qui avaient un diagnostic biologique positif d'ICV par la PCR à transcription inverse sur un échantillon plasmatique entre le 10 janvier et le 31 décembre 2014 étaient éligibles à l'inclusion. Le temps jusqu'au décès était le résultat principal. La relation indépendante entre les formes cliniques et le temps jusqu'au décès a été analysée à l'aide d'un modèle de Cox. RÉSULTATS: Au total, 268 patients ont été inclus. L'âge moyen était de 80 ± 8 ans, 53% étaient des femmes. La durée médiane du suivi était de 28 mois (intervalle: 0 à 39 ans). Au cours du suivi, 53 patients (19,8%) sont décédés. La durée médiane de survie était de 13,2 mois (intervalle: 0 à 33,6). A la fin du suivi, les taux de décès étaient de 4,6% pour les cas cliniques aigus, 19,0% pour les cas atypiques, 19,2% pour les cas aigus sévères et 23,5% pour les cas non classifiables. L'analyse multivariée a révélé que la forme clinique de l'IVC à l'admission était indépendamment associée à la survie à long terme (forme atypique: HR = 2,38; IC95%: 2,15-2,62; forme aiguë sévère: HR = 2,40; IC95%: 2,17-2,64; forme inclassable: HR = 2,28; IC95%: 2,06-2,51). CONCLUSION: La forme clinique lors de la présentation avec IVC a un impact significatif sur la survie à long terme. La prise en charge des patients atteints d'ICV devrait être adaptée à la forme clinique lors de l'admission.

RESUMO

Improving immunisation coverage for older adults is a public health issue. Since 2008, nurses have been authorised to vaccinate this population against influenza without a medical prescription. One study examined the opinions of a sample of 78 private duty nurses in Martinique on influenza and anti-tetanus vaccination of elderly populations. The majority of nurses said they were not in favour of vaccination.

RESUMO

BACKGROUND: The French West-Indies rank first for both prostate cancer incidence and mortality rates. Analyzing diagnostic and therapeutic procedures among patients with prostate cancer, using data from a population-based cancer registry, is essential for cancer surveillance and research strategies. METHODS: This retrospective observational cohort study was based on data from the Martinique Cancer Registry. Records of 452 patients diagnosed with prostate cancer in 2013 were retrieved from the registry. Data extracted were: socio-demographic and clinical characteristics, circumstances of diagnosis, PSA level at diagnosis, Gleason score and risk of disease progression. Stage at diagnosis and patterns of care among prostate cancer patients were analyzed. RESULTS: Mean age at diagnosis was 67 ± 8 years; 103 (28.5%) were symptomatic at diagnosis. Digital rectal exam was performed in 406 (93.8%). Clinical stage was available in 385 (85.2%); tumours were localized in 322/385 (83.6%). Overall, 17.9% were at low risk, 36.4% at intermediate and 31.9% at high risk; 13.8% were regional/metastatic cancers. Median PSA level at diagnosis was 8.16 ng/mL (range 1.4-5000 ng/mL). A total of 373 patients (82.5%) received at least one treatment, while 79 (17.5%) had active surveillance or watchful waiting. Among patients treated with more than one therapeutic strategy, the most frequent combination was external radiotherapy with androgen deprivation (n = 102, 22.6%). CONCLUSIONS: This study provides detailed data regarding the quality of diagnosis and management of patients with prostate cancer in Martinique. Providing data on prostate cancer is essential for the development of high-priority public health measures for the Caribbean.

RESUMO

PURPOSE: To determine whether self-rated health (SRH) is an independent predictor for mortality in older Afro-Caribbean patients hospitalised for an acute condition. METHODS: Prospective cohort of patients recruited from the University Hospitals of Martinique Acute Care for Elders unit. Patients aged 75 or older and hospitalised for an acute condition were eligible. The outcome was time to death within the 36-week follow-up. SRH was the explanatory variable of interest. Cox's Proportional Hazards model was used to estimate the relationship between SRH and mortality. RESULTS: The 223 patients included in the study were aged 85.1 ± 5.5 years. In total, 123 patients reported "very good to good" health, and 100 "medium to very poor" health. Crude mortality rates at six months, 1, 2, and 3 years were 30.5, 34.8, 48.4, and 57.0%, respectively. By multivariate analysis, SRH reached significant relationship for all mortality timepoints. The adjusted hazard ratios for subjects who perceived their health as medium, poor or very poor was 1.6-2.7 times greater than that of subjects who reported good or very good health. CONCLUSION: Assessment of SRH could have implications for clinical practice, particularly in helping practitioners to better estimate prognosis in the acute care settings.

RESUMO

PURPOSE: To determine whether self-rated health is a prognostic factor of six-week mortality, independently of other known objective prognostic factors. METHODS: The SAFMA study was a prospective cohort, which recruited patients from the University Hospital of Martinique Acute Care for Elders unit (French West Indies) from January to June 2012. Patients aged 75 or older and hospitalized for an acute condition were eligible. The outcome was time to death within the six-week follow-up. The main explanatory variable was self-rated health. Sociodemographic and clinical characteristics were considered as covariates. Cox's proportional hazards model was used. RESULTS: The mean age of the 223 patients included was 85.1 ± 5.5 years. Six-week mortality rate was 14.8 %; none were lost to follow-up. In total, 123 claimed "very good to good" health, and 100 "medium to very poor" health. Self-rated health was the only independent prognostic factor associated with 6-week mortality (hazard ratio 2.61; 95 % confidence interval 1.18-5.77; p = .02), when adjusting for known prognostic factors such as age, dimensions of the comprehensive geriatric assessment and comorbidity burden. CONCLUSION: The association between self-rated health and short-term mortality could have implications for clinical practice, particularly in helping in the estimation of prognosis in acute care setting.

RESUMO

The aim was to perform a systematic review of cases published in the literature to describe the management of high-output ileostomy (HOI) in older adults. A literature search was performed in PubMed©, and Scopus© for all publications up to March 1st, 2023. Case reports and/or case series reporting data from older adults on HOI management were included. Publication year, country, sex, age, aetiology of the stomy, time from ileostomy to HOI, daily volume threshold, Treatment regimen, and effectiveness were extracted. In total, 428 studies were identified, of which 9 (describing 10 cases) were included in this review. The mean age was 69.9 ± 4.7 years. The most frequent aetiology of ileostomy was occlusion. The daily volume considered to be excessive ranged from 1 to 2 litres per 24-hour period. The main side effects of HOI were dehydration, acute renal failure, and weight loss. Loperamide was the most frequently used drug. Most studies reported that non-pharmacological therapies were also used. No death was reported in any of the studies. In all, ileostomy exposes older individuals to complications. Medical therapy with loperamide coupled with rehydration seems to be efficacious in the medium term. Multidisciplinary management is advisable, in order to increase the chances of achieving ostomy reversal as early as possible, when indicated.

RESUMO

"Obesity paradox" describes the counterintuitive finding that aged overweight and obese people with a particular disease may have better outcomes than their normal weight or underweight counterparts. This systematic review was performed to summarize the publications related to the obesity paradox in older adults, to gain an in-depth understanding of this phenomenon. PubMed©, Embase©, and Scopus© were used to perform literature search for all publications up to 20 March 2022. Studies were included if they reported data from older adults on the relation between BMI and mortality. The following article types were excluded from the study: reviews, editorials, correspondence, and case reports and case series. Publication year, study setting, medical condition, study design, sample size, age, and outcome(s) were extracted. This review has been registered with PROSPERO (no. CRD42021289015). Overall, 2226 studies were identified, of which 58 were included in this systematic review. In all, 20 of the 58 studies included in this review did not find any evidence of an obesity paradox. Of these 20 studies, 16 involved patients with no specific medical condition, 1 involved patients with chronic diseases, and 2 involved patients with type 2 diabetes mellitus. Seven out of the nine studies that looked at short-term mortality found evidence of the obesity paradox. Of the 28 studies that examined longer-term mortality, 15 found evidence of the obesity paradox. In the studies that were conducted in people with a particular medical condition (n = 24), the obesity paradox appeared in 18 cases. Our work supports the existence of an obesity paradox, especially when comorbidities or acute medical problems are present. These findings should help guide strategies for nutritional counselling in older populations.

RESUMO

The aim of this study was to investigate the link between self-reported health (SRH) and mortality in older adults. In total, 505 studies were found in PubMed and Scopus, of which 26 were included in this review. In total, 6 of the 26 studies included did not find any evidence of an association between SRH and mortality. Of the 21 studies that included community dwellers, 16 found a significant relationship between SRH and mortality. In total, 17 studies involved patients with no specific medical conditions; among these, 12 found a significant link between SRH and mortality. Among the studies in adults with specific medical conditions, eight showed a significant association between SRH and mortality. Among the 20 studies that definitely included people younger than 80 years, 14 found a significant association between SRH and mortality. Of the twenty-six studies, four examined short-term mortality; seven, medium-term mortality; and eighteen, long-term mortality. Among these, a significant association between SRH and mortality was found in 3, 7, and 12 studies, respectively. This study supports the existence of a significant relation between SRH and mortality. A better understanding of the components of SRH might help guide preventive health policies aimed at delaying mortality in the long term.

RESUMO

OBJECTIVE: We aimed to identify risk factors for nursing home (NH) entry 36 months after hospitalization via the emergency department (ED) in a population of patients aged 75 years or older. METHODS: This was a prospective multicentre cohort. Patients were recruited from the emergency departments (EDs) of nine hospitals. Subjects had been hospitalised in a medical ward in the same hospital as the ED to which they were initially admitted. Subjects who experienced NH entry prior to ED admission were excluded. NH entry has been defined as the incident admission either into an NH or other long-term care facility within the follow-up period. Variables from a comprehensive geriatric assessment of patients were entered into a Cox model with competing risks to predict NH entry during 3 years of follow-up. RESULTS: Among 1306 patients included in the SAFES cohort, 218 (16.7%) who were already in an NH were excluded. The remaining 1088 patients included in the analysis were aged 84 ± 6 years on average. During 3 years of follow-up, 340 (31.3%) entered an NH. The independent risk factors for NH entry were that they: living alone (Hazard ratio (HR) 2.00, had a 95% confidence interval (CI) 1.59-2.54, p < 0.0001), could not independently perform activities of daily living (HR 1.81, 95% CI 1.24-2.64, p = 0.002), and had balance disorders (HR 1.37, 95% CI 1.09-1.73, p = 0.007), dementia syndrome (HR 1.80, 95% CI 1.42-2.29, p < 0.0001) and a risk of pressure ulcers (HR 1.42, 95% CI 1.10-1.82, p = 0.006). CONCLUSION: The majority of the risk factors for NH entry within 3 years after emergency hospitalization are amenable to intervention strategies. It is therefore reasonable to imagine that targeting these features of frailty could delay or prevent NH entry and improve the quality of life of these individuals before and after NH entry.

RESUMO

Older adults who are socially isolated or who feel lonely have a higher risk of morbidity and mortality. It is important to be able to assess them with efficient tools. The objective was to describe tools for assessing feelings of loneliness (FoL) and social isolation (SI) in older adults, and to estimate their prevalence. A systematic review was conducted including 18 studies. For FoL, the most frequently used tool was the UCLA Loneliness Scale. For SI, the most frequently used tool was the Lubben Social Network Scale. The median prevalences of FoL and SI were 24.1% and 42.5%, respectively. Both of these constructs will become more prominent in the coming decades; therefore, there is a need to identify the best tools.

RESUMO

PURPOSE: To derive and validate a 90-day unplanned hospital readmission (UHR) score based on information available to non-hospital based care providers. METHODS: Retrospective longitudinal study with cross-validation method. Participants were older adults (≥ 65 years) admitted to a geriatric short-stay department in a general hospital in France. Patients were split into a derivation cohort and a validation cohort. We recorded demographic information, medical history, and concurrent clinical characteristics. The main outcome was 90-day UHR. Data obtained from hospital discharge letters were used in a logistic regression model to construct a predictive score, and to identify risk groups for 90-day UHR. RESULTS: In total, 750 and 250 aged adults were included in both the derivation and the validation cohorts. Mean age was 87.2 ± 5.2 years, most were women (68.1%). Independent risk factors for 90-day UHR were: use of mobility aids (p = .02), presence of dementia syndrome (p = .02), history of recent hospitalisation (p = .03), and discharge to domiciliary home (p = .005). From these four risk factors, three groups were determined: low-risk group (score < 4), medium-risk group (score between 4 and 6), and high-risk group (score ≥ 6). In the derivation cohort the 90-day UHR rates increased significantly across risk groups (14%, 22%, and 30%, respectively). The 90-day UHR score had the same discriminant power in the derivation cohort (c-statistic = 0.63) as in the validation cohort (c-statistic = 0.63). CONCLUSIONS: This score makes it possible to identify aged adults at risk of 90-day UHR and to target multidisciplinary interventions to limit UHR for patients discharged from a Geriatric Short-Stay Unit.

RESUMO

The objective was to compare the profile and outcomes of older adults admitted to a geriatric short-stay unit for COVID-19, to those of older adults admitted to the same unit for seasonal influenza infection. This was an observational study performed in a General Hospital in France. Patients ≥ 70 years admitted to a geriatric short-stay unit for COVID-19 between March 18 and November 15, 2020 were included. They were compared with patients of the same age group, admitted to the same geriatric short-stay unit for seasonal influenza infection over the periods January to March 2019 and January to March 2020. Data collection included demographic information, medical history, clinical signs and symptoms, outcomes, and hospital discharge patterns. Descriptive and intergroup comparison analyses were performed. In total, 153 patients were included in the study, 82 in the seasonal influenza group, and 71 in the COVID-19 group. The average age was 87.6 ± 4.8 and 87.6 ± 6.5 years in the COVID-19 and seasonal influenza groups, respectively. There was no difference between groups regarding the Charlson comorbidity index (3.4 ± 3.0 versus 3.4 ± 2.8). The seasonal influenza group more often had fever, cough, sputum, and renal failure, whereas the COVID-19 group more often experienced diarrhea, and death. The COVID-19 group was frequently living in collective housing. The profile at admission of older adults hospitalized for COVID-19 or seasonal influenza infection was similar. Although fever and respiratory signs were less common in the COVID-19 group, these patients experienced more complications (such as renal failure or oxygen therapy requirement) and higher mortality.

RESUMO

The WHO defined three clinical forms for chikungunya virus infection (CHIKV, namely, acute, atypical, and severe cases) and a chronic form. These definitions seemed inappropriate for the elderly. So, we propose an adapted definition for elderly people. A cross-sectional analysis was performed including patients aged ≥ 65 years, who attended the emergency department with a positive biological diagnosis of CHIKV in 2014. A total of 267 elderly patients (80 ± 8 years) were included. When using the 2015 WHO definitions, 114 patients could not be classified (42.7%) in any of the category, of whom 43 (37.7%) reported absence of fever, 85 (74.6%) reported absence of joint pain, and 14 (12.3%) reported absence of both fever and joint pain. After adaptation of the WHO definitions, the 114 unclassifiable patients were reclassified as follows: eight as typical cases, 50 as atypical cases, 42 as severe cases, and 14 remained unclassifiable. The atypical clinical form was the most common form. The 2015 WHO definitions of the clinical forms at the acute phase of CHIKV are ill suited to the elderly. The adapted definition we propose here appears to be more appropriate and could help improved management of older patients with CHIKV.

RESUMO

BACKGROUND: Vitamin D has diverse and extensive effects on the immune system, including activating innate immunity and reducing the overactive adaptive immune response. A systematic review was performed to identify and synthesize the best available evidence on the association between vitamin D level and risk of COVID-19, adverse outcomes and possible benefits of supplementation in aged 60 years or over. METHODS: A literature search was performed in PubMed© and Scopus© for all publications from inception published before 15 March 2021. Studies reporting data from aged patients on vitamin D use and COVID-19 were included. Basic science articles, editorials and correspondence were excluded. Publication year, study design and setting, characteristics of the study population were extracted. This study is registered with PROSPERO, under the number CRD42020223993. RESULTS: In total, 707 studies were identified, of which 11 observational studies were included in the final review. Four studies compared vitamin D-supplemented COVID-19 patients to non-supplemented patients, and seven compared patients with vitamin D deficiency to patients without deficiency. In all four studies, patients with vitamin D supplementation had better rates of primary clinical outcomes (death, the severity of the disease, oxygen therapy requirement…). In studies comparing patients with vitamin D deficiency and patients without vitamin D deficiency, those without vitamin D deficiency had better primary clinical outcomes (death rate, the severity of the disease, oxygen therapy requirement, invasive mechanical ventilation need…). CONCLUSION: This systematic review seems to support an association between vitamin D deficiency and the risk of COVID-19 in aged people. In addition, vitamin D deficiency appears to expose these subjects to a greater risk of adverse outcomes. Because of its simplicity of administration, and the rarity of side effects, including vitamin D in preventive strategies for certain viral diseases, it appears to be an attractive option.

RESUMO

PURPOSE OF REVIEW: Although the chikungunya virus was discovered more than 60 years ago, it has only really been studied since the outbreak in La Reunion in 2005-2006. Ten years later, between 2014 and 2015, the chikungunya virus spread throughout the Americas, affecting millions of people. The objective of this review is to describe the contributions of research on chikungunya virus infection gained from epidemic in the West Indies and the Guiana Shield. RECENT FINDINGS: Prevalence data were similar to those found in the Indian Ocean or Asia during epidemics. Clinically, there is now a better understanding of the typical, atypical, and severe forms. Several studies have insisted on the presence of neurological forms of chikungunya infection, such as encephalitis or Guillain-Barré syndrome. Cases of septic shock due to chikungunya virus as well as thrombotic thrombocytopenic purpura were described for the first time. Given the magnitude of the epidemic and the large number of people affected, this has led to a better description and new classifications of chikungunya virus infections in specific populations such as pregnant women, the elderly, and children. Several studies also described the behavior of populations faced with an emerging disease. SUMMARY: Current epidemiological data from tropical regions highlights the risk of spreading emerging diseases at higher latitudes, especially concerning arboviruses, since the vector Aedes albopictus is already established in many parts of northern countries. A better understanding of the disease and its epidemic dynamics will foster better management, the crucial importance of which was demonstrated during the COVID-19 epidemic.

RESUMO

PURPOSE: The aim of this study was to investigate whether Chikungunya virus infection (CVI) was an independent risk factor for 2-year mortality in Afro-Caribbean subjects aged 65 years or older. PATIENTS AND METHODS: A retrospective cohort study was performed from January 2014 to December 2016 in the University Hospital of Martinique. Subjects aged ≥65 years admitted to the hospital were included. Baseline characteristics and concurrent manifestations at admission were collected. Subjects were followed up by phone for 2 years. RESULTS: A total of 687 old Afro-Caribbean subjects (80.4±8.0 years) were included: 467 positive for CVI (Chik+) and 220 negative for CVI (Chik-). During the follow-up, 180 (26.2%) died. The proportion of deaths was higher among Chik- (40.9%) than among Chik+ subjects (21.6%) (p<0.0001). By multivariable analysis, when adjusted for age polyarthralgia, neurological troubles, cardiovascular disorders, absence of neutrophilia, thrombocytopenia, hypernatremia, and hospital stay, Chik+ subjects had significantly higher survival rates (HR: 0.58; 95% CI: 0.40-0.85) than Chik- ones. CONCLUSION: Within the two years following hospital admission of subjects aged ≥65 years or older, Chik+ subjects had significantly higher survival rates than Chik- ones.

RESUMO

The aim of this study was to describe the predictive role of the modified SEGA frailty scale on nursing home admission, readmission to hospital, falls and mortality. MATERIAL AND METHODS: We performed a prospective, single-centre cohort study in patients discharged from a geriatric hospital ward between July 2016 and February 2017, with follow-up of six months. Patients aged 65 and over who were returning home from hospital were included. The primary outcome measure was admission to a nursing home at six months. We used a Cox model to explore the predictive nature of the variables. RESULTS: Thirty-three patients (18.4%) with a mean age of 80.9 years (± 6.5) were classified as not very frail and 146 (81.6%) with a mean age of 86 years (± 6.5) as frail/very frail. After six months, 13.5% of the frail/very frail patients and 1.2% of the not very frail patients had entered a nursing home (p = 0.169). Frailty status was significantly associated with readmission to hospital at three months (p = 0.026) and single or multiple falls at six months (p = 0.003). CONCLUSION: The modified SEGA scale may predict the occurrence of adverse events and improve the transition to home.
