In that context, 48 geriatric day hospitals (GDHs) have been financed by the government since January 1st 2006. The main objective of this study is to describe the patient characteristics, facility features and activities related to the Belgian GDHs. Methods: A prospective, multicenter study was performed from October 1st till December 31st 2006 in all 48 GDHs. For each GDH a transversal data collection was carried out. In the same period all patients scheduled for the GDHs were registered and followed for 3 months. Therefore two questionnaires were developed using Filemaker® software: one for each GDH and one for each patient . There were no exclusion criteria. Results: Six GDHs did not complete one or both questionnaires. Consequently, the results of 42 GDHs were included. GDHs with more year...

The aim of this study was to systematically review the literature comparing muscle fiber typing in the back muscles of healthy subjects with low back pain (LBP) patients. Predefined keywords regarding muscle fiber typing and back muscles were combined in PubMed and Web of Science electronic search engines from inception to August 2014. Full-text articles were independently screened by 2 independent, blinded researchers. Full texts fulfilling the predefined inclusion criteria were assessed on risk of bias by 2 independent researchers, and relative data were extracted. Data were not pooled because of heterogeneity in biopsy locations and population. From the 214 articles that were identified, 18 met the inclusion criteria. These articles evaluated the muscle fiber type distribution or proportional fiber type a...

Low muscle mass (dual-energy x-ray absorptiometry) was categorised as low appendicular lean mass (ALM; predefined <19.75 kg) or low ALM-to-BMI ratio (predefined <0.789). Frailty status was assessed using the components of weight loss, inability to rise from a chair and poor energy (SOF index). Survival time was calculated as the number of months from assessment in 2000 until death or up to 15 years of follow-up. mean age of the participants was 78.4 ± 3.5 years. Combined weakness and low muscle mass was present in 3-8% of men, depending on the criteria applied. Pre-frailty and frailty were present in 30 and 7% of men, respectively. After 15 years of follow-up, 165 men (86%) died. Both the presence of combined weakness and low ALM-to-BMI ratio (age-adjusted HR = 2.50, 95% CI = 1.30-4.79) and the presence of SOF frailty (age-adjusted HR = 2.64, 95% CI = 1.44-4.86) were associated with mortality. our findings confirm the predictive value for mortality of the non-distribution-based FNIH criteria and SOF index in older community-dwelling Belgian men.

In 80 patients aged 65 years and older medication history and ED drug administration were analysed. Medical records were analysed for ADRs by an expert panel which also evaluated their avoidability and causality. An interaction program was used to search for potential drug interactions followed by assessment for clinical significance. Data were analysed using a logistic regression model. The significance level was set at alpha=0.05. Eighty seven ADRs were identified in 37 patients; 18 were the result of an interaction (15 patients). Causality was assessed as definite (n=11), probable (n=62) and possible (n=24). The reason for admission was definitely and probably related to an ADR in 6 and 18 patients respectively. Only 17 (20%) of the ADRs were assessed as unavoidable, while 23 (26%) and 47 (54%) were classified as definitely and possibly avoidable, respectively. ADRs were related with female gender (p=0.023) and number of drugs (p=0.004), but not with high age (p=0.151). Clinically relevant interactions were related with older age (p=0.032) and number of drugs (p=0.003), but not with gender (p=0.380). None of the interactions with ED initiated medications were considered unjustified. ADRs frequently occur in the older patients admitted to the ED and are an important cause of hospital admissions with a substantial contribution of adverse drug interactions.

Implementation of clinical pharmacy services in Belgian hospitals has not been evident because these activities were initially not structurally financed. The aim is to describe the strengths and weaknesses of the clinical pharmacy development process, and the milestones that enhanced the progress. Furthermore, the organisation of clinical pharmacy in the Ghent University Hospital is explained, including back- and front-office activities, seamless pharmaceutical care and medication safety improvement. Some working methods, procedures and tools are explained for different clinical pharmacy services. In particular, the clinical pharmacy projects for geriatric patients as well as the preparation of clinical pharmacy services for the accreditation process are explained. We also reflect on the organisation model and the future development of clinical pharmacy, taking into consideration facilitators and potential barriers.

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

This systematic literature review aims to determine prevalence and type of PIP in community-dwelling older people across Europe, as well as identifying risk factors for PIP. The PubMed and Web of Science database were searched systematically for relevant manuscripts (January 1, 2000-December 31, 2014). Manuscripts were included if the study design was observational, the study participants were community-dwelling older patients in Europe, and if a published screening method for PIP was used. Studies that focused on specific pathologies or that focused on merely one inappropriate prescribing issue were excluded. Data analysis was performed using R statistics. Fifty-two manuscripts were included, describing 82 different sample screenings with an estimated overall PIP prevalence of 22.6 % (CI 19.2-26.7 %; range 0.0-98.0 %).

Consequently, potentially inappropriate prescribing (PIP) becomes more frequent. Systematic screening for PIP in older patients in primary care could yield a large improvement in health outcomes, possibly an important task for community pharmacists. In this article, we develop an explicit screening tool to detect relevant PIP that can be used in the typical community pharmacy practice, adapted to the European market. Eleven panellists participated in a two-round RAND/UCLA (Research and Development/University of California, Los Angeles) process, including a round zero meeting, a literature review, a first written evaluation round, a second face-to-face evaluation round and, finally, a selection of those items that are applicable in the contemporary community pharmacy. Eighteen published lists of PIP for older patients were retrieved from the literature, mentioning 398 different items. After the two-round RAND/UCLA process, 99 clinically relevant items were considered suitable to screen for in a community pharmacy practice. A panel of seven community pharmacists selected 83 items, feasible in the contemporary community pharmacy practice, defining the final GheOP³S tool. A novel explicit screening tool (GheOP³S) was developed to be used for PIP screening in the typical community pharmacy practice.
