Comparative effectiveness of pain management interventions for hip fracture: a systematic review.

BACKGROUND Pain management is integral to the management of hip fracture. PURPOSE To review the benefits and harms of pharmacologic and nonpharmacologic interventions for managing pain after hip fracture. DATA SOURCES 25 electronic databases (January 1990 to December 2010), gray literature, trial registries, and reference lists, with no language restrictions. STUDY SELECTION Multiple reviewers independently and in duplicate screened 9357 citations to identify randomized, controlled trials (RCTs); nonrandomized, controlled trials (non-RCTs); and cohort studies of pain management techniques in older adults after acute hip fracture. DATA EXTRACTION Independent, duplicate data extraction and quality assessment were conducted, with discrepancies resolved by consensus or a third reviewer. Data extracted included study characteristics, inclusion and exclusion criteria, participant characteristics, interventions, and outcomes. DATA SYNTHESIS 83 unique studies (64 RCTs, 5 non-RCTs, and 14 cohort studies) were included that addressed nerve blockade (n = 32), spinal anesthesia (n = 30), systemic analgesia (n = 3), traction (n = 11), multimodal pain management (n = 2), neurostimulation (n = 2), rehabilitation (n = 1), and complementary and alternative medicine (n = 2). Overall, moderate evidence suggests that nerve blockades are effective for relieving acute pain and reducing delirium. Low-level evidence suggests that preoperative traction does not reduce acute pain. Evidence was insufficient on the benefits and harms of most interventions, including spinal anesthesia, systemic analgesia, multimodal pain management, acupressure, relaxation therapy, transcutaneous electrical neurostimulation, and physical therapy regimens, in managing acute pain. LIMITATIONS No studies evaluated outcomes of chronic pain or exclusively examined participants from nursing homes or with cognitive impairment. Systemic analgesics (narcotics, nonsteroidal anti-inflammatory drugs) were understudied during the search period. CONCLUSION Nerve blockade seems to be effective in reducing acute pain after hip fracture. Sparse data preclude firm conclusions about the relative benefits or harms of many other pain management interventions for patients with hip fracture.

Recurrent Community-acquired Pneumonia in Patients Starting Acid-suppressing Drugs

BACKGROUND Several studies suggest that proton pump inhibitors (PPIs) and histamine 2-receptor antagonists (H2s) increase risk of community-acquired pneumonia. To test this hypothesis, we examined a prospective population-based cohort predisposed to pneumonia: elderly patients (> or =65 years) who had survived hospitalization for pneumonia. METHODS This study featured a nested case-control design where cases were patients hospitalized for recurrent pneumonia (> or =30 days after initial episode) and controls were age, sex, and incidence-density sampling matched but never had recurrent pneumonia. PPI/H2 exposure was classified as never, past, or current use before recurrent pneumonia. The association between PPI/H2s and pneumonia was assessed using multivariable conditional logistic regression. RESULTS During 5.4 years of follow-up, 248 recurrent pneumonia cases were matched with 2476 controls. Overall, 71 of 608 (12%) current PPI/H2 users had recurrent pneumonia, compared with 130 of 1487 (8%) nonusers (adjusted odds ratio [aOR] 1.5; 95% confidence interval [CI], 1.1-2.1). Stratifying the 608 current users according to timing of PPI/H2 initiation revealed incident current-users (initiated PPI/H2 after initial pneumonia hospitalization, n=303) bore the entire increased risk of recurrent community-acquired pneumonia (15% vs 8% among nonusers, aOR 2.1; 95% CI, 1.4-3.0). The 305 prevalent current-users (PPI/H2 exposure before and after initial community-acquired pneumonia hospitalization) were equally likely to develop recurrent pneumonia as nonusers (aOR 0.99; 95% CI, 0.63-1.57). CONCLUSION Acid-suppressing drug use substantially increased the likelihood of recurrent pneumonia in high-risk elderly patients. The association was confined to patients initiating PPI/H2s after hospital discharge. Our findings should be considered when deciding to prescribe these drugs in patients with a recent history of pneumonia.

Factors influencing pharmacists’ adoption of prescribing: qualitative application of the diffusion of innovations theory

BackgroundIn 2007, Alberta became the first Canadian jurisdiction to grant pharmacists a wide range of prescribing privileges. Our objective was to understand what factors influence pharmacists’ adoption of prescribing using a model for the Diffusion of Innovations in healthcare services.MethodsPharmacists participated in semi-structured telephone interviews to discuss their prescribing practices and explore the facilitators and barriers to implementation. Pharmacists working in community, hospital, PCN, or other settings were selected using a mix of random and purposive sampling. Two investigators independently analyzed each transcript using an Interpretive Description approach to identify themes. Analyses were informed by a model explaining the Diffusion of Innovations in health service organizations.ResultsThirty-eight participants were interviewed. Prescribing behaviours varied from non-adoption through to product, disease, and patient focused use of prescribing. Pharmacists’ adoption of prescribing was dependent on the innovation itself, adopter, system readiness, and communication and influence. Adopting pharmacists viewed prescribing as a legitimization of previous practice and advantageous to instrumental daily tasks. The complexity of knowledge required for prescribing increased respectively in product, disease and patient focused prescribing scenarios. Individual adopters had higher levels of self-efficacy toward prescribing skills. At a system level, pharmacists who were in practice settings that were patient focused were more likely to adopt advanced prescribing practices, over those in product-focused settings. All pharmacists stated that physician relationships impacted their prescribing behaviours and individual pharmacists’ decisions to apply for independent prescribing privileges.ConclusionsDiffusion of Innovations theory was helpful in understanding the multifaceted nature of pharmacists’ adoption of prescribing. The characteristics of the prescribing model itself which legitimized prior practices, the model of practice in a pharmacy setting, and relationships with physicians were prominent influences on pharmacists’ prescribing behaviours.

The cure of ageing: vitamin D—magic or myth?

Vitamin D was initially thought only to function in calcium homeostasis. However, it has multiple roles in human health, including neuromuscular and immune modulation. Recently, its deficiency is increasingly implicated in many diseases. This discovery has led both popular culture and research to find ways that vitamin D can either treat or prevent many diseases. Since vitamin D not only affects the expression of many genes, but also has intra-individual pharmacokinetic variation, a simplistic cause and effect between vitamin D deficiency and illnesses should not be expected. Older adults pose a challenge not only because diseases become more prevalent with ageing, but they also are often complicated with other comorbidities. This article reviews the link of vitamin D deficiency and the associated medical conditions in middle aged and older adults. It also examines the variability in testing vitamin D values and evaluates dosing recommendations based on current evidence.

Considerations in the treatment of geriatric depression: Overview of pharmacotherapeutic and psychotherapeutic treatment interventions.

Geriatric (or late-life) depression is common in older adults, with an incidence that increases dramatically after age 70 to 85, as well as among those admitted to hospitals and those who reside in nursing homes. In this population, depression promotes disability and is associated with worsened outcomes of comorbid chronic medical diseases. Geriatric depression is often undetected or undertreated in primary care settings for various reasons, including the (incorrect) belief that depression is a normal part of aging. Current research suggests that while antidepressant agent use in older adults is improving in quality, room for improvement exists. Improving the pharmacotherapy of depression in older adults requires knowledge and understanding of many clinical factors. The purpose of this review is to discuss salient issues in geriatric depression, with a focus on pharmacotherapeutic and psychotherapeutic interventions.

Knowledge of risk factors for falling reported by patients with Parkinson disease

&NA; This study examined awareness of the risk factors for falling among a group of community dwelling patients with Parkinson disease (PD) using the Falls Risk Awareness Questionnaire (FRAQ). A cross‐sectional survey of 28 patients who attended a Movement Disorders Clinic for treatment of PD was used. FRAQ is a 28‐item self‐administered survey that assesses the knowledge and perception of risk factors for falling. Demographic, medical, and medication data were gathered from both the participants and clinic charts. Twenty‐three (82%) of the participants reported falls in the past; seven (30%) had fallen within the past month. Nineteen (68%) of the participants felt they were at risk for further falls. When asked to list potential risk factors for falling, only 14% could identify medication as a risk factor. Persons with PD are at substantial risk of falling, yet many appear to be unaware of common risk factors, especially medication use.

Providing health information to older adults

Providing information to older adults is essential for informed decision-making and good health. Because there are significant deficits in providing information verbally, health professionals must use written information as well. Most studies have focused on the content and literacy of documents. However, the legibility and formatting are critically important for older adults, who are more likely to suffer with visual impairment. Providing written information that is tested for appropriate reading level and for presentation is necessary to ensure that older adults can use the information given. There are a number of tools available that test these aspects of written information, but not one tool that is universally accepted. Further research regarding the design and presentation of written information for older adults is necessary.

Administration Technique and Acceptance of Inhaler Devices in Patients With Asthma or COPD

Background: Correct technique and patient acceptance of inhalation devices for lung disease influence successful long-term management. Patient ability to use the proper technique may differ depending on the device as well as patient factors. Objectives: The objectives of our study are to measure self-reported level of acceptability of inhaler devices in community settings and compare correct use of inhaler devices using a novel scale for measuring appropriate inhaler technique. Methods: This prospective observational study enrolled patients from 3 different practice sites with asthma and/or chronic obstructive pulmonary disease (COPD) who were using an inhaler device. In addition to describing the samples’ overall acceptability and correct use scores for the different inhalers, acceptability and correct use scores were compared based on patient characteristics. Results: A total of 161 patients completed the study. The results show that acceptability was lowest for the pressurized metered dose inhaler (pMDI) with a spacer (S); effective use was best demonstrated with pMDI and poorest with pMDI-S. Older patients were found to be more accepting of the HandiHaler device than younger patients. Patients reporting taking more inhaled drugs were found to be more accepting of the pMDI-S than those taking fewer drugs. Finally, patients reporting taking more inhaled drugs demonstrated less-effective use of the HandiHaler device than patients taking fewer drugs. Conclusion: Pulmonary disease duration does not ensure improved use for all inhalers; patients taking more drugs demonstrate less-effective use for some devices. Assessment of patient acceptance and factors that predict the ability to use a device should be considered to individualize therapy.

Survey of pharmacist prescribing practices in Alberta

PURPOSE Results of a survey to characterize pharmacist prescribing in the Canadian province of Alberta are reported. METHODS A cross-sectional survey of a random sample of pharmacists registered with the Alberta College of Pharmacists was conducted. The survey was developed in four stages, with evidence of reliability and construct validity compiled. Analysis of variance and chi-square testing were used to compare prescribing behaviors. RESULTS Three hundred fifty of 692 invited pharmacists (51%) completed the survey, with 76.9% and 11.1% indicating that they practiced in community and hospital settings, respectively, and 12.0% practicing in a consultant role (i.e., on a primary care team or in a long-term care setting). Overall, 93.4% of the pharmacists had prescribed. The most common practices were renewing prescriptions for continuity of therapy (92.3%), altering doses (74.3%), and substituting a medication due to a shortage (80.6%). Twenty-three pharmacists (6.6%) indicated that they did not prescribe because they were on an interprofessional team, had a consulting role, or preferred to fax physicians to request orders. Pharmacists with additional prescribing authorization (6.3% of the total survey population) were more likely to prescribe to adjust ongoing medications (63.6%) than to initiate a new medication (18.2%). CONCLUSION A survey showed that Alberta pharmacists prescribed in a manner that mirrored their practice environment. Compared with other groups, hospital and consultant pharmacists were more likely to adapt prescriptions, and community pharmacists were more likely to renew medications. Pharmacists in rural areas were prescribing most frequently.

Physicians’ use of computerized clinical decision supports to improve medication management in the elderly – the Seniors Medication Alert and Review Technology intervention

Background Elderly people (aged 65 years or more) are at increased risk of polypharmacy (five or more medications), inappropriate medication use, and associated increased health care costs. The use of clinical decision support (CDS) within an electronic medical record (EMR) could improve medication safety. Methods Participatory action research methods were applied to preproduction design and development and postproduction optimization of an EMR-embedded CDS implementation of the Beers’ Criteria for medication management and the Cockcroft–Gault formula for estimating glomerular filtration rates (GFR). The “Seniors Medication Alert and Review Technologies” (SMART) intervention was used in primary care and geriatrics specialty clinics. Passive (chart messages) and active (order-entry alerts) prompts exposed potentially inappropriate medications, decreased GFR, and the possible need for medication adjustments. Physician reactions were assessed using surveys, EMR simulations, focus groups, and semi-structured interviews. EMR audit data were used to identify eligible patient encounters, the frequency of CDS events, how alerts were managed, and when evidence links were followed. Results Analysis of subjective data revealed that most clinicians agreed that CDS appeared at appropriate times during patient care. Although managing alerts incurred a modest time burden, most also agreed that workflow was not disrupted. Prevalent concerns related to clinician accountability and potential liability. Approximately 36% of eligible encounters triggered at least one SMART alert, with GFR alert, and most frequent medication warnings were with hypnotics and anticholinergics. Approximately 25% of alerts were overridden and ~15% elicited an evidence check. Conclusion While most SMART alerts validated clinician choices, they were received as valuable reminders for evidence-informed care and education. Data from this study may aid other attempts to implement Beers’ Criteria in ambulatory care EMRs.
