    Adverse drug reactions in older people : detection and prevention

    Get PDF
    Adverse drug reactions (ADRs) in older adults are an important healthcare problem since they are frequently a cause of hospitalization, occur commonly during admission, and are an important cause of morbidity and mortality. Older adults are particularly susceptible to ADRs because they are usually on multiple drug regimens and because age is associated with changes in pharmacokinetics and pharmacodynamics. The presentation of an ADR in older adults is often atypical, which further complicates its recognition. One potential strategy for improving recognition of ADRs is to identify those patients who are at risk of an ADR. The recently developed GerontoNet ADR Risk Score is a practical tool for identification of older patients who are at increased risk for an ADR and who may represent a target for interventions aimed at reducing ADRs. Provision of adequate education in the domain of clinical geriatric pharmacology can improve recognition of ADRs. Besides formal surveillance systems, built-in computer programs with electronic prescribing databases and clinical pharmacist involvement in patient care within multidisciplinary geriatric teams might help to minimize the occurrence of ADRs. In addition, a number of actions can be taken in hospitals to stimulate appropriate prescribing and to assure adequate communication between primary and hospital care. In older adults with complex medical problems and needs, a global evaluation obtained through a comprehensive geriatric assessment may be helpful in simplifying drug prescription and prioritizing pharmacological and healthcare needs, resulting in an improvement in quality of prescribing

    For People Living with Dementia (PLwD), wandering behaviour can cause undesired consequences, such as falling, getting lost or even fatalities. For caregivers, taking care of PLwD with wandering behaviours is burdensome. If not intervened early, some wandering behaviours will escalate into crisis events. This design research aims to explore how to convert the wandering behaviour to a guided activity with the minimum input from caregivers by intervening early, that is, engaging PLwD, to avoid potential escalations. Based on Need-driven Dementia-compromised Behaviour (NDB) model, Crisis Development model and via a co-design approach, we developed De-light. De-light is a set of interactive sticks enhanced by light, audio and tactile experiences. Based on the degree of wandering behaviours of PLwD, De-light can be placed by the caregiver in a safe and suitable area in the nursing home to provide a controlled setting for guiding PLwD to perform physical activity. Our design research implies the possibilities of applying NDB model, Crisis Development model, and co- design approach in designing for the wandering behaviours for PLwD

    Older patients' prescriptions screening in the community pharmacy: development of the Ghent Older People's Prescriptions community Pharmacy Screening (GheOP3S) tool

    Get PDF
    Background: Ageing of the population often leads to polypharmacy. 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. Methods: 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. Results: 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. Conclusion: A novel explicit screening tool (GheOP3S) was developed to be used for PIP screening in the typical community pharmacy practice

    The influence of drug use on fall incidents among nursing home residents: A systematic review

    Get PDF
    Background: Falls are a major health problem among the elderly, particularly in nursing homes. Abnormalities of balance and gait, psychoactive drug use, and dementia have been shown to contribute to fall risk. Methods: We conducted a systematic review of the literature to investigate which psychoactive drugs increase fall risk and what is known about the influence of these drugs on gait in nursing home residents with dementia. We included studies with a prospective cohort design on psychoactive drug use in nursing homes with dementia residents and with falls as an outcome measure. Results: Seventeen studies were included in the review. Pooled risk estimates were not calculated because there was no homogeneity across studies. We assessed the strength of evidence for psychoactive drugs as a prognostic factor for falls by defining four levels of evidence: strong, moderate, limited or inconclusive. Strong evidence was defined as consistent findings (≥80%) in at least two high quality cohorts. We found strong evidence that the use of multiple drugs (3/3 cohorts, effect sizes 1.30-1xs0.30), antidepressants (10/12 cohorts, effect sizes 1.10-7.60), and anti-anxiety drugs (2/2 cohorts, effect sizes 1.22-1.32) is associated with increased fall risk. The evidence for the association of other psychoactive drug classes with fall risk was limited or inconclusive. Conclusions: Research on the contribution of psychoactive drugs to fall risk in nursing home residents with dementia is limited. The scarce evidence shows, however, that multiple drugs, antidepressants and anti-anxiety drugs increase fall risk in nursing home populations with residents with dementia

    A systematic review of non-pharmacological interventions for BPSD in nursing home residents with dementia: from a perspective of ergonomics

    Get PDF
    Background: Non-pharmacological interventions for Behavioral and Psychological Symptoms of Dementia (BPSD) have been developed; however, a systematic review on the effectiveness of this type of intervention from a perspective of ergonomics is lacking. According to ergonomics, the capabilities of Persons with Dementia (PwD) should be considered in the interventions for the outcomes to be reliable. We aimed to systematically review the non-pharmacological interventions for BPSD in nursing home residents with an additional assessment criterion based on ergonomics, specifically, capability consideration. Methods: The electronic databases MEDLINE, EMBASE, and PsycINFO were searched for nonpharmacological interventions treating BPSD in nursing homes. The interventions were categorized according to the capabilities of PwD required to participate. Study quality was assessed by National Health and Medical Research Council (NHMRC) evidence hierarchy and the capability consideration. Results: Sixty-four clinical trials met the inclusion criteria; 41 trials reported a significant reduction in at least one BPSD symptom; 20 trials reported no significant reduction in BPSD symptoms; three trials reported adverse effects after the intervention. Interventions were categorized into sensory-, cognition-, and movementoriented. Capabilities of PwD were not considered in 28 trials, especially for sensory capabilities. Conclusions: The majority of the clinical trials reported a significant reduction in BPSD. The quality of evidence for nonpharmacological interventions in these trials is low due to the lack of capability consideration, data inhomogeneity, and inadequate study design and reporting. Future studies should focus on improving the quality of evidence by including capability consideration and examining if a relationship between capability consideration and effectiveness of non-pharmacological interventions exists

    Why older people refuse to participate in falls prevention trials: A qualitative study

    Get PDF
    Background/Objectives: Falls are a major public health problem. Older persons are frequently underrepresented in trials, including falls prevention trials. Insight into possible reasons for non-participation could help to improve trial designs and participation rates among this age-group. The aim of this study was to explore reasons why older people refuse to participate in falls prevention trials. Setting: A qualitative study. Participants: Community-dwelling adults aged ≥ 65. years who attended the Emergency Department due to a fall and refused to participate in a falls prevention trial (IMPROveFALL-study). Measurements: A structured interview guide was used, and interview transcripts were subjected to an independent content analysis by two researchers. Results: 15 interviews were conducted. A main reason to refuse trial participation was mobility impairment. In contrast, younger and more "active" and mobile seniors considered themselves "too healthy" to participate. Persons with multiple comorbidities mentioned that they attended a hospital too often, or experienced adequate follow-up by their own physicians already. Transport problems, including distance to the hospital, parking facilities, and travel expenses were another issue. During the interviews it was emphasized by the patients, that they knew the reason for their fall. However, they were not familiar with the positive effects of falls prevention programmes. Conclusions: Older persons reported multiple reasons to refuse participation in a falls prevention study, such as health-related factors, several practical problems, and personal beliefs about the causes and preventability of falls. Anticipation of those issues might contribute to an improvement in participation rates of older fallers, shorter study duration, and a better generalizability of research findings

    The impact of falls in the elderly

    The number of falls in the elderly is becoming a major public health problem in our society. In the past decade, life expectancy has increased from 75 years in 1990 to 79 years in 2009 in the US. It has been estimated that the number of persons aged 65 years and older in the US will double by 2050. In 2000, falls accounted for 45% of all injury-related inpatient stays with almost 750,000 hospitalizations. Fractures were the most common primary injury diagnosis, including 314,006 hip fractures. Injury following a fall is associated with a decreased quality of life and poor functional outcome, in severe injuries these effects continue for a prolonged period of time. In 2006, fall-related medical costs in the population aged ≥65 in the US amounted to US19billionfornon−fatalandUS19 billion for non-fatal and US0.2 billion for fatal injuries. In this article, we provide a literature overview on the impact of falls in the elderly, the demands on healthcare, and the costs for our society

    Perioperative care of the older patient

    Get PDF
    Nearly 60% of the Dutch population undergoing surgery is aged 65 years and over. Older patients are at increased risk of developing perioperative complications (e.g., myocardial infarction, pneumonia, or delirium), which may lead to a prolonged hospital stay or death. Preoperative risk stratification calculates a patient's risk by evaluating the presence and extent of frailty, pathophysiological risk factors, type of surgery, and the results of (additional) testing. Type of anesthesia, fluid management, and pain management affect outcome of surgery. Recent developments focus on multimodal perioperative care of the older patient, using minimally invasive surgery, postoperative anesthesiology rounds, and early geriatric consultation
