Greater number of narcotic analgesic prescriptions for osteoarthritis is associated with falls and fractures in elderly adults

Pharmacological management of pain in Australian Aged Care Facilities

BACKGROUND

up to 80% of residents in aged care facilities (ACFs) experience pain, and previous studies have found that older patients with pain are often undertreated. Few studies have been conducted in Australia evaluating the use of analgesic therapy in ACF residents.

OBJECTIVE

to explore the use of analgesics among ACF residents, including independent predictors of analgesic use, evaluate analgesic use against pain management guidelines and identify potential medication management issues.

METHODS

a retrospective analysis of 7,309 medicines reviews conducted on Australian ACF residents was undertaken. Medication use was compared with published guidelines relating to the management of pain in elderly patients or ACF residents. Multiple variable logistic regression was used to identify independent predictors of analgesic use.

RESULTS

nearly 91% of residents were prescribed analgesics. Of those, 2,057 residents were taking regular opioids (28.1%). Only 50% of those taking regular opioids received regular paracetamol at doses of 3-4 g/day. The concurrent use of sedatives was high, with 48.4% of those taking regular opioids also taking an anxiolytic/hypnotic.

CONCLUSION

there is a need to optimise the prescribing and administration of regular paracetamol as a first line and continuing therapy for pain management in ACF residents, to potentially improve pain management and reduce opioid requirements. Furthermore, with the risk of falls and fractures increased by concurrent use of opioids and sedatives, the widespread use of these drugs in a population already at high risk was concerning, indicating a need for better education of health professionals in this area.

High prevalence of falls, fear of falling, and impaired balance in older adults with pain in the United States: findings from the 2011 National Health and Aging Trends Study

OBJECTIVES

To determine the prevalence of clinically relevant falls-related outcomes according to pain status in older adults in the United States.

DESIGN

Cross-sectional analysis of the 2011 National Health and Aging Trends Study, a sample of Medicare enrollees aged 65 and older (response rate 71.0%).

SETTING

In-person assessments were conducted in the home or residential care facility of the sampled study participant.

PARTICIPANTS

Individuals aged 65 and older (n = 7,601, representing 35.3 million Medicare beneficiaries).

MEASUREMENTS

Participants were asked whether they had been "bothered by pain" and the location of pain, as well as questions about balance and coordination, fear of falling, and falls.

RESULTS

Fifty-three percent of the participants reported bothersome pain. The prevalence of recurrent falls in the past year (≥ 2 falls) was 19.5% in participants with pain and 7.4% in those without (age- and sex-adjusted prevalence ratio (PR) = 2.63, 95% confidence interval (CI) = 2.28-3.05). The prevalence of fear of falling that limits activity was 18.0% in those with pain and 4.4% in those without (adjusted PR = 3.98, 95% CI = 3.24-4.87). Prevalence of balance and falls outcomes increased with number of pain sites. For example, prevalence of problems with balance and coordination that limited activity was 6.6% in participants with no pain, 11.6% in those with one site of pain, 17.7% in those with two sites, 25.0% in those with three sites, and 41.4% in those with four or more sites (P < .001 for trend). Associations were robust to adjustment for several potential confounders, including cognitive and physical performance.

CONCLUSION

Falls-related outcomes were substantially more common in older adults with pain than in those without. Accordingly, pain management strategies should be developed and evaluated for falls prevention.

Costs and Consequences: A Review of Discharge Opioid Prescribing for ongoing Management of Acute Pain

Over recent years there has been a growing need for patients to be sent home from hospital with prescribed opioids for ongoing management of their acute pain. Increasingly complex surgery is being performed on a day-stay or 23-hour-stay basis and inpatients after major surgery and trauma are now discharged at a much earlier stage than in the past. However, prescription of opioids to be self-administered at home is not without risk. In addition to the potential for acute adverse effects, including opioid-induced ventilatory impairment and impairment of driving skills, a review of the literature shows that opioid use continues in some patients for some years after surgery. There are also indications that over-prescription of discharge opioids occur with a significant amount not consumed, resulting in a potentially large pool of unused opioid available for later use by either the patient or others in the community. Concerns about the potential for harm arising from prescription of opioids for ongoing acute pain management after discharge are relatively recent. However, at a time when serious problems resulting from the non-medical use of opioids have reached epidemic proportions in the community, all doctors must be aware of the potential risks and be able to identify and appropriately manage patients where there might be a risk of prolonged opioid use or misuse. Anaesthetists are ideally placed to exercise stewardship over the use of opioids, so that these drugs can maintain their rightful place in the post-discharge analgesic pharmacopoeia.

COX-2 inhibition: what we learned--a controversial update on safety data

IMPORTANCE

Cyclooxygenase type 2 (COX-2)-selective nonsteroidal anti-inflammatory drugs (NSAIDs) (c2sNSAIDs) have been scrutinized relative to the less costly nonselective NSAIDs (nsNSAIDs). The conclusions reached were not always consistent with the data, and best treatment choices for patients were not always recommended.

OBJECTIVE

The data that were used to criticize the c2sNSAIDs are reexamined in a controversial light, demonstrating that the presence of reverse bias was often, but not always, present.

EVIDENCE REVIEW

A review of both Pubmed and news media articles relating to nsNSAIDs and c2sNSAIDs was conducted. References were selected on the basis of relevance to the controversies.

FINDINGS

The initial claims for the c2sNSAIDs of reduced gastrointestinal (GI) injury and preservation of platelet function were soon dwarfed by concerns regarding increased cardiovascular (CV) risk with publication of the Vioxx Gastrointestinal Outcomes Research trial for rofecoxib. Initial prothrombotic theories had a poor basis for explaining these concerns and have since largely been replaced with more credible explanations, including blood pressure elevations known to occur with all NSAIDs. Between data suggesting increased CV risk and under political pressure and public outcry, rofecoxib was withdrawn from the market in 2004. Soon, all c2sNSAIDs were under scrutiny. The Food and Drug Administration has since grouped all NSAIDs, whether c2sNSAID or nsNSAID, into one class with similar warnings regarding skin, CV, renal, and GI side effects.

CONCLUSIONS AND RELEVANCE

The entire "COX-2 debacle" is reminiscent of past events with NSAIDs. Amid this public, media, and political hysteria, it is not clear if we will see any more NSAIDs (selective or otherwise) approved in the near future.

Effects of drug pharmacokinetic/pharmacodynamic properties, characteristics of medication use, and relevant pharmacological interventions on fall risk in elderly patients

BACKGROUND

Falls among the elderly are an issue internationally and a public health problem that brings substantial economic and quality-of-life burdens to individuals and society. Falls prevention is an important measure of nursing quality and patient safety. Numerous studies have evaluated the association of medication use with fall risk in elderly patients. However, an up-to-date review has not been available to summarize the multifaceted pharmaceutical concerns in the prevention of medication-related falls.

MATERIALS AND METHODS

Relevant literature was identified by performing searches in PubMed, Web of Science, and the Cochrane Library, covering the period until February 2014. We included studies that described an association between medications and falls, and effects of drug pharmacokinetic/pharmacodynamic properties, characteristics of medication use, and pharmacological interventions on fall risk in elderly patients. The full text of each included article was critically reviewed, and data interpretation was performed.

RESULTS

Fall-risk-increasing drugs (FRIDs) include central nervous system-acting agents, cough preparations, nonsteroidal anti-inflammatory drugs, anti-Alzheimer's agents, antiplatelet agents, calcium antagonists, diuretics, α-blockers, digoxin, hypoglycemic drugs, neurotoxic chemotherapeutic agents, nasal preparations, and antiglaucoma ophthalmic preparations. The degree of medication-related fall risk was dependent on one or some of the following factors: drug pharmacokinetic/pharmacodynamic properties (eg, elimination half-life, metabolic pathway, genetic polymorphism, risk rating of medications despite belonging to the same therapeutic class) and/or characteristics of medication use (eg, number of medications and drug-drug interactions, dose strength, duration of medication use and time since stopping, medication change, prescribing appropriateness, and medication adherence). Pharmacological interventions, including withdrawal of FRIDs, pharmacist-conducted clinical medication review, and computerized drug alerts, were effective in reducing fall risk.

CONCLUSION

Based on the literature review, clear practical recommendations for clinicians to prevent falls in the elderly included making a list of FRIDs, establishing a computerized alert system for when to e-prescribe FRIDs, seeking an alternative drug with lower fall risk, withdrawing FRIDs if clinically indicated, taking pertinent cautions when the use of FRIDs cannot be avoidable, paying attention to prescribing appropriateness, simplifying the medication regimen, strengthening pharmacist-conducted clinical medication review, ensuring the label of each FRID dispensed contains a corresponding warning sign, being careful when medication change occurs, enhancing medication adherence, and mandating for periodic reassessment of potential risk associated with the patient's medication regimen. Further studies should be conducted in this area, such as investigating whether medication reconciliation and improving medication adherence could decrease the rate of falls.

As quedas no cenário da velhice: conceitos básicos e atualidades da pesquisa em saúde

Quedas têm sido referidas como importante fator de risco para redução da capacidade funcional em indivíduos idosos. Por sua alta prevalência nesta população, um dos objetivos das pesquisas foi delinear a queda sob seus aspectos causais e respectivas consequências. Com base nessas definições, é possível apontar perspectivas para a atuação da saúde na mitigação dos efeitos deste evento, bem como reduzir o alto gasto hospitalar destes idosos para a saúde pública. Dentro da lógica citada, este trabalho traz algumas das principais considerações e consensos da atualidade sobre queda, a partir da análise de pesquisas recentes. Tem como objetivo propor uma visão ampliada, capaz de divulgar os aspectos ligados à queda que são de interesse comum a todos os profissionais de saúde que lidam com essa população. Metodologia: utilizaram-se as bases Cochrane, Pubmed e Medline para busca das informações pretendidas através de descritores correspondentes às palavras Envelhecimento e Quedas e tendo como limite os anos 2009 a 2013. Resultados: Definiu-se para esta discussão os artigos ligados a aspectos epidemiológicos, fatores associados, consequências da queda, prevenção e intervenção nas quedas. Conclusão: Em resumo, o suporte multiprofissional está alicerçado nas práticas preventivas de quedas e necessita, portanto, de uma postura compartilhada de informações entre os profissionais da saúde que trabalham com este público.

Factors associated with re-presentation to emergency departments in elderly people with pain

Objectives To identify medical, social and demographic factors associated with increased risk of 30-day re-presentation to the emergency department (ED) in elderly people presenting with pain. Methods We undertook a single site, prospective observational study of all patients aged >65 years discharged from the ED with pain. Data were collected on possible medical, social and demographic predictors of ED readmission. Participants were a subset of all elderly patients presenting to the ED with pain, and received follow-up case management as part of the hospital’s rapid response, assessment and care planning program for elderly people. Results Over 8 months, 356 people were eligible for inclusion in the study; of these, 189 consented to case management and to participate in the study. Three factors statistically increased odds of re-presentation to ED within 30 days: (1) prescription of opioids (P = 0.003); (2) the presence of Home and Community Care Services (P = 0.03); and (3) the absence of a gait aid (P = 0.019). Nineteen per cent of eligible patients re-presented to ED within 30 days of initial presentation. Conclusion These findings contribute to current debate about opioid prescription and effective pain management in the elderly. The study highlights the need for routine follow-up care of older people discharged from the ED with pain, particularly those discharged home with opioids or with complex care needs. What is known about the topic? Re-presentation rates within 28 days for all-comers to the emergency department (ED) are collected and reported as part of routine service monitoring and evaluation. Presentation rates for elderly people to EDs have been escalating over the past decade; however, the risk factors that lead to re-presentations for elderly people have not been documented. Similarly, increasing concern about the prescription of opioids in elderly people is documented; however, its impact on ED re-presentations has not been reported. Innovative models of care are emerging to stem the rise in ED demand; however, their role and impact on re-presentation rates are not documented for this subgroup of ED presenters. What does this paper add? This research has demonstrated that ED re-presentation rates for elderly people with pain are higher than overall ED re-presentation rates. This article has identified three risk factors that significantly increase the risk of re-presentation in this population, including the prescription of opioid analgesics. Qualitative data have identified that elderly people prescribed opioids require extensive education and support to manage the medication side effects. What are the implications for practitioners? Practitioners should be aware that elderly people with pain are a higher risk group for ED re-presentation, particularly those prescribed opioid analgesics or with complex care needs. Discharge planning and assessment of supports should be routinely instigated to manage medication side effects, and follow-up services put in place where inadequate. Improved provision of written information in multiple languages for patients who cannot read English should also be initiated.
