The assessment and management of pain in the demented and non-demented elderly patient

Abstract

Persistent pain is a frequent health problem in the elderly. Its prevalence ranges from 45% to 80%. Chronic diseases, such as depression, cardiovascular disease, cancer and osteoporosis have a higher prevalence in aged individuals and increase the risk of developing chronic pain. The presence of pain is known to be associated with sleep disorders in these patients, as well as functional impairment, decreased sociability and greater use of the health system, with consequent increase in costs. Alzheimer's disease patients seem to have a normal pain discriminative capacity and they may probably have weaker emotional and affective experience of pain when compared to other types of dementia. Many patients have language deficits and thus cannot properly describe its characteristics. In more advanced cases, it becomes even difficult to determine whether pain is present or not. Therefore, the evaluation of these patients should be performed in a systematic way. There are three ways to measure the presence of pain: by direct questioning (self-report), by direct behavioral observation and by interviews with caregivers or informants. In recent years, many pain scales and questionnaires have been published and validated specifically for the elderly population. Some are specific to patients with cognitive decline, allowing pain evaluation to be conducted in a structured and reproducible way. The next step is to determine the type of painful syndrome and discuss the bases of the pharmacological management, the use of multiple medications and the presence of comorbidities demand the use of smaller doses and impose contraindications against some drug classes. A multiprofessional approach is the rule in the management of these patients.

Doenças crônicas, como depressão, distúrbios cardiovasculares, câncer e osteoporose tem alta prevalência em indivíduos idosos e aumentam o risco de desenvolver dor crônica. Nestes indivíduos, a presença de dor está associada a distúrbios do sono, prejuízo funcional, diminuição da sociabilidade e maior procura dos serviços de saúde, com o consequente aumento dos custos de saúde. Pacientes com Alzheimer têm uma capacidade discriminativa dolorosa normal e uma experiência afetiva e emocional da dor mais atenuada quando comparados com outros tipos de demência. Muitos pacientes

Post-Operative Pain Management Practices in Patients with Dementia - The Current Situation in Finland

“…In the last decade, there has been a growing interest about pain in older people [39, 40]. Research is needed to develop effective strategies for managing pain among older patients with dementia in the acute-care setting [19].…”

Towards improved decision support in the assessment and management of pain for people with dementia in hospital: a systematic meta-review and observational study

“…For some, the areas of focus were the processes of pain assessment and/or pain management/interventions in the elderly population, including (but not always limited to) persons with dementia (e.g. in Rutledge et al, 75 Rutledge and Donaldson, 76 Andrade et al 77 and Miller and Talerico…”

Opioids for persistent pain in older adults

“…Many patients with mild to moderate dementia can verbally communicate pain reliably, 64 but more challenging are those who are nonverbal, for whom providers depend on caregiver reports and observational scales. 65 Prescribing in patients with dementia who When starting or changing the dose of opioid, counsel patients about driving and safety are verbal and nonverbal mirrors the strategies used in those older adults who are cognitively intact, 66 eg:…”
