Adult vaccination for pneumococcal disease: a comparison of the national guidelines in Europe.

Pneumococcal disease constitutes a major global health problem. Adults aged over 50 years and younger adults with specific chronic health conditions are at risk for invasive pneumococcal disease, associated with substantial morbidity and mortality. In Europe, two vaccine types are used in adults for pneumococcal immunization: pneumococcal polysaccharide vaccine (PPV23) and pneumococcal conjugate vaccine (PCV13). To provide an overview and to compare the national guidelines for pneumococcal immunization for adults in Europe. In November 2016, national guidelines on pneumococcal vaccination for adults of 31 European countries were obtained by Google search, the website of European Centre for Disease Prevention and Control, and contacting public health officials. In our analysis, we distinguished between age-based and risk-based guidelines. In October 2017, we used the same method to retrieve guideline updates. We observed great variability regarding age, risk groups, vaccine type, and use of boosters. In age-based guidelines, vaccination is mostly recommended in adults aged over 65 years using PPV23. Boosters are generally not recommended. An upper age limit for vaccination is reported in three countries. In the immunocompromised population, vaccination with both vaccines and administration of a booster is mostly recommended. In the population with chronic health conditions, there is more heterogeneity according vaccine type, sequence, and administration of boosters. Asplenia is the only comorbidity for which all countries recommend vaccination. The great variability in European pneumococcal vaccination guidelines warrants European unification of the guidelines for better control of pneumococcal disease.

Determining clinically important differences in health-related quality of life in older patients with cancer undergoing chemotherapy or surgery.

PURPOSE: Using the EORTC Global Health Status (GHS) scale, we aimed to determine minimal clinically important differences (MCID) in health-related quality of life (HRQOL) changes for older cancer patients with a geriatric risk profile, as defined by the geriatric 8 (G8) health screening tool, undergoing treatment. Simultaneously, we assessed baseline patient characteristics prognostic for HRQOL changes. METHODS: Our analysis included 1424 (G8 ≤ 14) older patients with cancer scheduled to receive chemotherapy (n = 683) or surgery (n = 741). Anchor-based methods, linking the GHS score to clinical indicators, were used to determine MCID between baseline and follow-up at 3 months. A threshold of 0.2 standard deviation (SD) was used to exclude MCID estimates too small for interpretation. Logistic regressions analysed baseline patient characteristics prognostic for HRQOL changes. RESULTS: The 15-item Geriatric Depression Scale (GDS15), Visual Analogue Scale (VAS) for Fatigue and ECOG Performance Status (PS) were selected as clinical anchors. In the surgery group, MCID estimates for improvement and deterioration were ECOG PS (5*, 11*), GDS15 (5*, 2) and VAS Fatigue (3, 9*). In the chemotherapy group, MCID estimates for improvement and deterioration were ECOG PS (8*, 7*), GDS15 (5, 4) and VAS Fatigue (5, 5*). Estimates with * were > 0.2 SD threshold. Patients experiencing pain or malnutrition (surgery group) or fatigue (chemotherapy group) at baseline showed a significantly stable or improved HRQOL (p < 0.05) after their treatment. CONCLUSION: The reported MCID for improvement and deterioration depended on the anchor used and treatment received. The estimates can be used to evaluate significant changes in HRQOL and to determine sample sizes in clinical trials.

Adherence to geriatric assessment-based recommendations in older patients with cancer: a multicenter prospective cohort study in Belgium.

Background: In the general older population, geriatric assessment (GA)-guided treatment plans can improve overall survival, quality of life and functional status (FS). In GA-related research in geriatric oncology, studies mainly focused on geriatric screening and GA but not on geriatric recommendations, interventions and follow-up. The aim of this study was to investigate the adherence to geriatric recommendations and subsequent actions undertaken in older patients with cancer. Patient and methods: A prospective Belgian multicenter (N = 22) cohort study included patients ≥70 years with a malignant tumor upon oncologic treatment decision. Patients with an abnormal result on the geriatric screening (G8 ≤14/17) underwent GA. Geriatric recommendations were formulated based on GA results. At follow-up the adherence to geriatric recommendations was documented including a description of actions undertaken. Results: From November 2012 till February 2015, G8 screening was carried out in 8451 patients, of which 5838 patients had an abnormal result. Geriatric recommendations data were available for 5631 patients. Geriatric recommendations were made for 4459 patients. Geriatric interventions data were available for 4167 patients. A total of 12 384 geriatric recommendations were made. At least one different geriatric recommendation was implemented in 2874 patients. A dietician, social worker and geriatrician intervened most frequently for problems detected on the nutritional, social and functional domain. A total of 7569 actions were undertaken for a total of 5725 geriatric interventions, most frequently nutritional support and supplements, extended home care and psychological support. Conclusions: This large-scale Belgian study focuses on the adherence to geriatric recommendations and subsequent actions undertaken and contributes to the optimal management of older patients with cancer. We identified the domains for which geriatric recommendations are most frequently made and adhered to, and which referrals to other health care workers and facilities are frequently applied in the multidisciplinary approach of older patients with cancer.

Postoperative complications in individuals aged 70 and over undergoing elective surgery for colorectal cancer.

AIM: This study aims to describe the nature, incidence, severity and outcomes of in-hospital postoperative complications (POCs) in older patients undergoing elective surgery for colorectal cancer. METHOD: Patients ≥ 70 years old were identified from a prospectively collected database (2009-2015) focusing on the implementation of geriatric screening and assessment in patients with cancer. Medical and surgical POCs were retrieved retrospectively from the medical records, and the severity of the POCs was graded by the Clavien-Dindo (CD) grading system. The following outcomes were analysed comparing patients with and without CD ≥ 2 and CD ≥ 3 POCs: length of stay (LOS), transfer to the intensive care unit, 30-day readmission rates, 30-day and 1-year mortality. RESULTS: In the 190 patients included, medical POCs (40.5%) were more frequent than surgical POCs (17.9%), and 37.9% experienced CD ≥ 2 POCs. The most common medical POCs were infections (26.8%), transient confusion or altered mental function (12.1%), cardiac arrhythmia (4.7%), and ileus/gastroparesis/prolonged recovery of transit (4.7%). The most common surgical POCs were surgical site infections (12.1%), wound dehiscence/bleeding (4.7%), anastomotic leak (3.7%) and surgical site bleeding (3.7%). The reoperation rate was 7.9%. CD ≥ 2 POCs led to 11 intensive care unit admissions and increased median postoperative LOS by 114% (P < 0.0001 for both), but did not significantly alter 30-day readmission and 30-day and 1-year mortality rates. CD ≥ 3 POCs increased LOS by 162% (P < 0.0001) and showed an increased 1-year mortality (P = 0.07). CONCLUSION: This study shows that in-hospital medical and surgical complications after surgery for colorectal cancer in patients ≥ 70 years old are frequent and that complications lead to less favourable outcomes.

Geriatric Assessment and Functional Decline in Older Patients with Lung Cancer.

PURPOSE: Older patients with lung cancer are a heterogeneous population making treatment decisions complex. This study aims to evaluate the value of geriatric assessment (GA) as well as the evolution of functional status (FS) in older patients with lung cancer, and to identify predictors associated with functional decline and overall survival (OS). METHODS: At baseline, GA was performed in patients ≥70 years with newly diagnosed lung cancer. FS measured by activities of daily living (ADL) and instrumental activities of daily living (IADL) was reassessed at follow-up to define functional decline and OS was collected. Predictors for functional decline and OS were determined. RESULTS: Two hundred and forty-five patients were included in this study. At baseline, GA deficiencies were present in all domains and ADL and IADL were impaired in 51 and 63% of patients, respectively. At follow-up, functional decline in ADL was observed in 23% and in IADL in 45% of patients. In multivariable analysis, radiotherapy was predictive for ADL decline. No other predictors for ADL or IADL decline were identified. Stage and baseline performance status were predictive for OS. CONCLUSIONS: Older patients with lung cancer present with multiple deficiencies covering all geriatric domains. During treatment, functional decline is observed in almost half of the patients. None of the specific domains of the GA were predictive for functional decline or survival, probably because of the high impact of the aggressiveness of this tumor type leading to a poor prognosis.

Epidemiology and outcome of invasive pneumococcal disease among adults in Belgium, 2009-2011.

This epidemiological study examined morbidity and case fatality of invasive pneumococcal disease (IPD) in adults in Belgium as well as distribution and antibiotic susceptibility of Streptococcus pneumoniae serotypes.Adults hospitalised with microbiologically proven IPD were prospectively enrolled. The study started in 2009 with patients aged ≥50 years, whereas in 2010 and 2011, patients aged ≥18 years were included. The clinical presentation, patient profile, treatment, outcome, and mortality were recorded during hospitalisation.Outcome was also assessed one month afterdischarge. Of the 1,875 patients with IPD identified, 1,332 were included in the analysis. Bacteraemic pneumonia, affecting 1,049 of the patients, was the most frequent IPD type (79%), and chronic obstructive pulmonary disease and cancer were the main comorbidities.One-third of patients required admission to intensive care unit. A total of 208 (16%) patients died during hospitalisation and an additional 21 (2%) within one month after discharge. Case fatality rates of ≥20%were observed in patients with chronic heart failure, hepatic disease, and renal insufficiency. Serotypes 7F, 1, 19A, and 3 were the most prevalent and together accounted for 47% (569/1,214) of all IPD cases and 42% (80/189) of mortality. Of the patient isolates, 21% (255/1,204) were resistant to erythromycin and 22% (264/1,204) to tetracycline. Penicillin non-susceptibility was mostly found in serotype 19A isolates. These baseline data are essential when assessing the impact of pneumococcal conjugate vaccination in adults in the future.

Relevance of a systematic geriatric screening and assessment in older patients with cancer: results of a prospective multicentric study.

BACKGROUND: To evaluate the large-scale feasibility and usefulness of geriatric screening and assessment in clinical oncology practice by assessing the impact on the detection of unknown geriatric problems, geriatric interventions and treatment decisions. PATIENTS AND METHODS: Eligible patients who had a malignant tumour were ≥70 years old and treatment decision had to be made. Patients were screened using G8; if abnormal (score ≤14/17) followed by Comprehensive Geriatric Assessment (CGA). The assessment results were communicated to the treating physician using a predefined questionnaire to assess the topics mentioned above. RESULTS: One thousand nine hundred and sixty-seven patients were included in 10 hospitals. Of these patients, 70.7% had an abnormal G8 score warranting a CGA. Physicians were aware of the assessment results at the time of treatment decision in two-thirds of the patients (n = 1115; 61.3%). The assessment detected unknown geriatric problems in 51.2% of patients. When the physician was aware of the assessment results at the time of decision making, geriatric interventions were planned in 286 patients (25.7%) and the treatment decision was influenced in 282 patients (25.3%). CONCLUSION: Geriatric screening and assessment in older patients with cancer is feasible at large scale and has a significant impact on the detection of unknown geriatric problems, leading to geriatric interventions and adapted treatment.

Highly Variable Paracetamol Pharmacokinetics After Multiple Oral Dosing in Frail Older People: A Population Pharmacokinetic Analysis.

INTRODUCTION: Paracetamol pharmacokinetics (PK) is highly variable in older fit adults after intravenous administration. Frailty and oral administration likely result in additional variability. The aim was to determine oral paracetamol PK and variability in geriatric inpatients. METHODS: A population PK analysis, using NONMEM 7.2, was performed on 245 paracetamol samples in 40 geriatric inpatients (median age 87 [range 80-95] years, bodyweight 66.4 [49.3-110] kg, 92.5% frail [Edmonton Frail Scale]). All subjects received paracetamol 1000 mg as tablet (72.5%) or granulate (27.5%) three times daily. Simulations of dosing regimens (1000 mg every 6 hours [q6h] or q8h) were performed to determine target attainment, using mean steady-state concentration (Css-mean) of 10 mg/L as target. RESULTS: A one-compartment model with first order absorption and lag time best described the data. The inter-individual variability was high, with absorption rate constant containing the highest variability. The inter-individual variability could not be explained by covariates. Simulations of 1000 mg q6h and q8h resulted in a Css-mean of 10.8 [25-75th percentiles 8.2-12.7] and 8.13 [6.3-9.6] mg/L, respectively, for the average geriatric inpatient. The majority of the population remained off-target (22.2% [q6h] and 52.2% [q8h] <8 mg/L; 31.3 [q6h] and 7.6% [q8h] >12 mg/L). CONCLUSION: A population of average geriatric inpatients achieved target Css-mean with paracetamol 1000 mg q6h, while q8h resulted in underexposure for the majority of them. Due to high unexplained variability, a relevant proportion remained either above or below the target concentration of 10 mg/L. Research focusing on PK, efficacy and safety is needed to recommend dosing regimens.

Clinical evaluation of the Copan ESwab for methicillin-resistant Staphylococcus aureus detection and culture of wounds.

The screening for and diagnosis of bacteriological infections often involves the collection and transportation of swab samples. The Copan ESwab was compared with the dry cotton Copan swab for methicillin-resistant Staphylococcus aureus (MRSA) screening (n = 200 paired samples) and with the Amies agar gel swab (Copan) for the sampling of burn and orthopaedic wounds (n = 203 paired samples) in terms of Gram staining and bacterial recovery. Gram stains performed with ESwab liquid showed significantly more Gram-negative rods, streptococci, Gram-positive cocci, Gram-positive rods, polymorphonuclear cells, lymphocytes and red blood cells than Gram stains from dry swabs. Bacterial recovery was significantly higher with ESwab (p < 0.01, for both MRSA screening and wounds, quantitative/semi-quantitative method). This lead to a slightly higher detection rate of MRSA (128 vs. 124 MRSA-positive ESwabs and dry swabs, respectively, p = 0.50) and a higher detection rate of coagulase-negative Staphylococcus spp. (44 isolates with ESwab vs. 29 with Amies gel swab, p = 0.001) and Enterococcus spp. (15 isolates with ESwab vs. 7 isolates with Amies gel swab, p = 0.005) with ESwab (quantitative method). We confirmed that ESwab has a high performance for Gram stains and a higher bacterial recovery than dry and Amies gel swabs when using clinical samples for MRSA screening and wound sampling.

[Generalized or targeted screening for carriage of MRSA on admission to a geriatric hospital]. / Veralgemeende of selectieve screening voor dragerschap van methicilline resistente Staphylococcus aureus bij opname op een geriatrische dienst.

OBJECTIVES: To confirm previously risk factors for MRSA carriage in our geriatric patient population and to suggest a simplified risk score with a combination of these risk factors, to test the Novel Score and to check if a targeted MRSA screening on admission is possible to reduce the screening workload and cost. DESIGN: a prospective in-hospital cohort study. SUBJECTS: 1125 geriatric patients were screened for MRSA carriage within 24 hours after admission to a geriatric hospital. METHODS: Risk factors, based on recently published risk scores (Preop Score and Ger Score) were determined. RESULTS: Prevalence of MRSA carriage was 8.44%. In a multivariate analysis age > or = 87 year (OR 1,864; 95% CI 1,145-3,035), presence of a long-term catheter (OR 2,813; 95% CI 1,562-5,065) and prior carriage of MRSA (OR 13,25; 95% CI 8,007-21,926) remained predictors of MRSA carriage. The Novel Score (cut-off > or = 1) had a sensitivity of 73.7%, a specificity of 64%, PPV 15.9%, NPV 96.3% and AUC of 0.688. The Novel Score allows reduction of the screening load by 57.2%, but misses 26% of positive cases. 16% of MRSA carriers develop an infection that needs to be treated with vancomycin. CONCLUSION: With targeted MRSA screening on admission based on a risk score a substantial reduction of workload and costs is possible compared to generalized screening for MRSA. Because MRSA carriers can be missed with a risk score, the epidemiological context and the risk of transmission and infection with MRSA must be taken in to account when introducing a targeted screening.

[Liver disease in the elderly]. / Leverlijden bij oudere personen.

A non-negligible percentage of the morbidity and mortality in older persons is due to liver disease. A discussion of the clinical presentation and proposed treatment of selected liver diseases in the elderly is therefore appropriate. Based on literature we will discuss the clinical course and treatment modalities of viral and autoimmune hepatitis, hepatocellular carcinoma and drug induced liver injury in the elderly.

[Prediction of functional decline in elderly patients discharged from the accident and emergency department]. / Predictie van functionele achteruitgang bij ambulante geriatrische patiënten op de spoedgevallendienst.

AIM: The aim of this study is to investigate the predictive validity of 5 screening tools with respect to functional decline in older persons discharged from the Accident & Emergency Department. METHODS: The Identification of Seniors at Risk (ISAR), Triage Risk Screening Tool (TRST), questionnaire of Runciman, questionnaire of Rowland and the Voorlopige Indicator voor Plaatsing (VIP) were collected in 83 older persons discharged from the Emergency Department of the University Hospitals of Leuven. Functional decline was derived from the Katz-scale, reflecting the condition 14 days before admission, at admission, 14, 30 and 90 days after discharge. RESULTS: The screening tools with the highest sensitivity and negative predictive value at 14 days after discharge were the questionnaire of Rowland and the ISAR. Thirty and ninety days after discharge, the ISAR was most sensitive and predictive. CONCLUSION: Sensitivity and negative predictive value are the most important parameters for screening tools. Hence, our study suggests that the ISAR instrument is the most appropriate instrument to predict functional decline in ambulatory older persons admitted to the emergency department. The ISAR can easily be integrated in nursing records and can be systematically employed in older persons at the emergency department.

Pharmacological treatment of osteoporosis in the oldest old.

The incidence of osteoporotic fractures increases with age. Consequently, the global prevalence of osteoporotic fractures will increase with the aging of the population. In old age, osteoporosis is associated with a substantial burden in terms of morbidity and mortality. Nevertheless, osteoporosis in old age continues to be underdiagnosed and undertreated. This may, at least partly, be explained by the fact that evidence of the antifracture efficacy of osteoporosis treatments comes mainly from randomized controlled trials in postmenopausal women with a mean age of 70-75 years. However, in the last years, subgroup analyses of these landmark trials have been published investigating the efficacy and safety of osteoporosis treatment in the very elderly. Based on this evidence, this narrative review discusses the pharmacological management of osteoporosis in the oldest old (≥80 years). Because of the high prevalence of calcium and/or vitamin D deficiency in old age, these supplements are essential in the management of osteoporosis in the elderly people. Adding antiresorptive or anabolic treatments or combinations, thereof, reduces the risk of vertebral fractures even more, at least in the elderly with documented osteoporosis. The reduction of hip fracture risk by antiresorptive treatments is less convincing, which may be explained by insufficient statistical power in some subanalyses and/or a higher impact of nonskeletal risk factors in the occurrence of hip fractures. Compared with younger individuals, a larger absolute risk reduction is observed in the elderly because of the higher baseline fracture risk. Therefore, the elderly will benefit more of treatment. In addition, current osteoporosis therapies also appear to be safe in the elderly. Although more research is required to further clarify the effect of osteoporosis drugs in the elderly, especially with respect to hip fractures, there is currently sufficient evidence to initiate appropriate treatment in the elderly with osteoporosis and osteoporotic fractures.

A Belgian Survey on Geriatric Assessment in Oncology Focusing on Large-Scale Implementation and Related Barriers and Facilitators.

OBJECTIVES: The aim of this study is to describe a large-scale, Belgian implementation project about geriatric assessment (=GA) in daily oncology practice and to identify barriers and facilitators for implementing GA in this setting. Design / setting / participants: The principal investigator of every participating hospital (n=22) was invited to complete a newly developed questionnaire with closed- and open-ended questions. The closed-ended questions surveyed how GA was implemented. The open-ended questions identified barriers and facilitators for the implementation of GA in daily oncology practice. Descriptive statistics and conventional content analysis were performed as appropriate. RESULTS: Qualifying criteria (e.g. disease status and cancer type) for GA varied substantially between hospitals. Thirteen hospitals (59.1%) succeeded to screen more than half of eligible patients. Most hospitals reported that GA data and follow-up data had been collected in almost all screened patients. Implementing geriatric recommendations and formulating new geriatric recommendations at the time of follow-up are important opportunities for improvement. The majority of identified barriers were organizational, with high workload, lack of time or financial/staffing problems as most cited. The most cited facilitators were all related to collaboration. CONCLUSION: Interventions to improve the implementation of GA in older patients with cancer need to address a wide range of factors, with organization and collaboration as key elements. All stakeholders, seeking to improve the implementation of GA in older patients with cancer, should consider and address the identified barriers and facilitators.

Vaccinaties en ouderen: een update : Praktijkgerichte geriatrische bijdrage.

: Vaccination of the elderly: an update Vaccination of the elderly still requires attention. The vaccination coverage for tetanus , influenza and pneumococcal infections is merely 40, 60 and 30 %, respectively. Besides a reduction in mortality (67 %) and a reduction of hospitalisation for pneumonia and influenza (50 %), vaccination against influenza also results in a decrease in cardio- and cerebrovascular morbidity (20%) as well as in a decrease in the frequency of doctor visits for respiratory infections for COPD patients. Vaccination of children and health care personnel can further reduce transmission of influenza and subsequent influenza related complications in the elderly. Pneumococcal invasive disease can be reduced by 50 % through vaccination. Vaccination of children with the conjugate vaccine can further reduce the incidence of pneumococcal invasive disease in the elderly. Further improvements in vaccine coverage levels are needed, mainly among elderly persons, children and persons at increased risk.

Acute infectieuze (niet Clostridium difficile geassocieerde) diarree bij ouderen : Klinische les.

Acute diarrhoea, non-antibiotic associated, is a common problem and a significant cause of morbidity and mortality in old age. In most cases diarrhoea has an infectious etiology. A number of different micro organisms can cause infectious diarrhoea. Most frequent are viral infections with a benign evolution. Rehydration is the only important therapeutic measure. Infections with bacteria are less common, antibiotics should be prescribed only in severe cases, and when there is suspicion of invasive infections by enteropathogenic bacteria.

[Antibiotic associated diarrhea and Clostridium difficile associated diarrhea in the elderly]. / Antibiotica geassocieerde en Clostridium difficile geassocieerde diarree bij ouderen.

Antibiotic associated diarrhea (AAD) is a common complication when antibiotics are used and is frequent in the elderly. It has an impact on the length of hospital stay and increases the comorbidity. Together with the type of antibiotic that is given, the length of antibiotical treatment and the combination of antibiotics is more predictive for the evolution of diarrhea when compared to the total given dose. Mostly AAD is benign, but an infection with C. difficile should always be excluded. C. difficile-enterocolitis is frequent among residents in nursing homes and in hospitalised patients. The clinical presentation varies from asymptomatic colonisation tot severe debilitating disease. A rapid diagnosis can be performed by detection of C. difficile toxin by an enzyme-linked immunoassay. Oral metronidazole and oral vancomycine are equally effective in the therapy. In relapsing infection an extended tapering regimen is sometimes necessary.
