Changing the channel: a qualitative analysis of an innovative video intervention to explore resident attitudes towards interprofessional collaboration on a Geriatric Medicine Unit.

Background: Medical learners develop a more positive attitude toward Interprofessional Collaboration (IPC) following Interprofessional Education (IPE) programs. However, IPE is not standardized, and the most effective teaching tool is unclear. The purpose of our study was to develop an IPE teaching tool for medical residents during an inpatient geriatric medicine rotation at an academic hospital, evaluate and explore the impact of the program on resident attitudes towards teamwork, and identify barriers and facilitators to interprofessional collaboration. Methods: An innovative video was developed which simulated a common IPC scenario. Near the start of the rotation, learners watched the video then participated in a facilitated discussion around principles of IPE, using the Canadian Interprofessional Health Collaborative (CIHC) framework, which highlights interprofessional communication, patient-centered care, role clarification, team functioning, collaborative leadership, and interprofessional conflict resolution. At the end of their four-week rotation, focus groups were conducted to explore resident attitudes towards IPE. The Theoretical Domain Framework (TDF) was used for qualitative analysis. Results: Data from 23 participants in five focus groups were analyzed using the TDF framework. Residents were able to identify barriers and facilitators to IPC in five TDF domains: environmental context and resources, social/professional role and identity, knowledge, social influences, and skills. Their observations correlated with the CIHC framework. Conclusion: The use of a scripted video and facilitated group discussion gave insights into residents' attitudes, perceived barriers, and facilitators towards IPC on a geriatric medicine unit. Future research could explore the use of this video intervention in other hospital services where team-based care is important.

Contexte: Les apprenants en médecine développent une attitude plus positive à l'égard de la collaboration interprofessionnelle (CIP) après avoir suivi un programme de formation interprofessionnelle (FIP). Toutefois, la FIP n'est pas standardisée et on ne sait pas quel outil d'enseignement est le plus efficace. Le but de notre étude était d'élaborer un outil de FIP pour les résidents en stage de gériatrie dans un hôpital universitaire, d'évaluer et d'explorer les effets du programme sur les attitudes des résidents à l'égard du travail d'équipe, et de recenser les facteurs qui entravent ou facilitent la collaboration interprofessionnelle. Méthodes: Une capsule vidéo innovante simulant un scénario courant de CIP a été créée. Au début de leur stage de résidence, les apprenants ont regardé la capsule et participé à une discussion animée sur les principes de la CIP, conformément au référentiel du Consortium pancanadien pour l'interprofessionnalisme en santé (CPIS), qui prône notamment la communication interprofessionnelle, les soins centrés sur le patient, la clarification des rôles, le fonctionnement de l'équipe, le leadership collaboratif et la résolution des conflits interprofessionnels. À la fin de leur stage de quatre semaines, des groupes de discussion ont été organisés pour explorer les attitudes des résidents à l'égard de la CIP. Un cadre de domaines théoriques (Theoretical Domains Framework) a été appliqué pour réaliser l'analyse qualitative. Conclusion: Au moyen d'une capsule scénarisée et d'une discussion de groupe dirigée, nous avons pu cerner les attitudes des résidents d'une unité de gériatrie par rapport à la CIP ainsi que leurs perceptions quant aux facteurs qui peuvent l'entraver ou la faciliter. Des travaux futurs pourraient explorer le recours à cette formule d'enseignement de la CIP dans d'autres services hospitaliers où les soins en équipe sont importants.

The MedSafer Study-Electronic Decision Support for Deprescribing in Hospitalized Older Adults: A Cluster Randomized Clinical Trial.

IMPORTANCE: Scalable deprescribing interventions may reduce polypharmacy and the use of potentially inappropriate medications (PIMs); however, few studies have been large enough to evaluate the impact that deprescribing may have on adverse drug events (ADEs). OBJECTIVE: To evaluate the effect of an electronic deprescribing decision support tool on ADEs after hospital discharge among older adults with polypharmacy. DESIGN, SETTING, AND PARTICIPANTS: This was a cluster randomized clinical trial of older (≥65 years) hospitalized patients with an expected survival of more than 3 months who were admitted to 1 of 11 acute care hospitals in Canada from August 22, 2017, to January 13, 2020. At admission, participants were taking 5 or more medications per day. Data analyses were performed from January 3, 2021, to September 23, 2021. INTERVENTIONS: Personalized reports of deprescribing opportunities generated by MedSafer software to address usual home medications and measures of prognosis and frailty. Deprescribing reports provided to the treating team were compared with usual care (medication reconciliation). MAIN OUTCOMES AND MEASURES: The primary outcome was a reduction of ADEs within the first 30 days postdischarge (including adverse drug withdrawal events) captured through structured telephone surveys and adjudicated blinded to intervention status. Secondary outcomes were the proportion of patients with 1 or more PIMs deprescribed at discharge and the proportion of patients with an adverse drug withdrawal event (ADWE). RESULTS: A total of 5698 participants (median [range] age, 78 [72-85] years; 2858 [50.2%] women; race and ethnicity data were not collected) were enrolled in 3 clusters and were adjudicated for the primary outcome (control, 3204; intervention, 2494). Despite cluster randomization, there were group imbalances, eg, the participants in the intervention arm were older and had more PIMS prescribed at baseline. After hospital discharge, 4989 (87.6%) participants completed an ADE interview. There was no significant difference in ADEs within 30 days of discharge (138 [5.0%] of 2742 control vs 111 [4.9%] of 2247 intervention participants; adjusted risk difference [aRD] -0.8%; 95% CI, -2.9% to 1.3%). Deprescribing increased from 795 (29.8%) of 2667 control to 1249 (55.4%) of 2256 intervention participants [aRD, 22.2%; 95% CI, 16.9% to 27.4%]. There was no difference in ADWEs between groups. Several post hoc sensitivity analyses, including the use of a nonparametric test to address the low cluster number, group imbalances, and potential biases, did not alter study conclusions. CONCLUSIONS AND RELEVANCE: This cluster randomized clinical trial showed that providing deprescribing clinical decision support during acute hospitalization had no demonstrable impact on ADEs, although the intervention was safe and led to improvements in deprescribing.

Stroke as an atypical initial presentation of giant cell arteritis.

BACKGROUND: Giant cell arteritis (GCA) is an immune mediated inflammatory disease of medium and large arteries which afflicts older people. The classical presentation features include: headache, visual disturbances, and jaw claudication. Patients diagnosed with GCA have also been observed to be at higher risk for the subsequent development of strokes. CASE PRESENTATION: We describe a case of an 84-year old right-handed man who presented to hospital with dysarthria, dysphagia, right-sided facial drop, a history of generalized weakness and multiple falls. He was admitted to geriatric medicine with the working diagnosis of a posterior circulation stroke syndrome. He was also started on antibiotic treatment for a possible community-acquired pneumonia because of the presence of a low-grade fever and a chest radiograph showing ill-defined left lower lobe airspace disease. Initial lab results were remarkable for an erythrocyte sedimentation rate (ESR) of 112 mm/h and a C-reactive protein (CRP) level of 110 mg/L consistent with an active inflammatory state. Neurovascular imaging showed mild atherosclerotic changes of the aortic arch and proximal great vessels without significant stenosis. The patient was started on daily high-dose prednisone because of the possibility of a cerebral vasculitis. Bilateral biopsy of temporal arteries showed giant cell arteritis. The patient's neurologic status and inflammatory markers significantly improved (ESR 52 mm/h, CRP 7.0 mg/L) and he was eventually discharged to a seniors home with services. CONCLUSION: The initial presentation of giant cell arteritis as a stroke syndrome, especially in the posterior circulation territory, is exceedingly rare. Other atypical presenting symptoms may include chronic cough and fever of unknown origin. The elevated ESR and CRP levels were clues to the diagnosis and clinical decision-making should be driven by a high index of suspicion since no single test (ESR, CRP, temporal artery biopsy) has perfect sensitivity. Elevated CRP may have a role in increasing stroke risk. This case report illustrates that in older people clinicians must consider atypical presentations of disease more often since timely diagnosis and initiation of treatment can result in optimal outcomes.

Time is of the essence: an observational time-motion study of internal medicine residents while they are on duty.

BACKGROUND: The effects of changes to resident physician duty hours need to be measureable. This time-motion study was done to record internal medicine residents' workflow while on duty and to determine the feasibility of capturing detailed data using a mobile electronic tool. METHODS: Junior and senior residents were shadowed by a single observer during six-hour blocks of time, covering all seven days. Activities were recorded in real-time. Eighty-nine activities grouped into nine categories were determined a priori. RESULTS: A total of 17,714 events were recorded, encompassing 516 hours of observation. Time was apportioned in the following categories: Direct Patient Care (22%), Communication (19%), Personal tasks (15%), Documentation (14%), Education (13%), Indirect care (11%), Transit (6%), Administration (0.6%), and Non-physician tasks (0.4%). Nineteen percent of the education time was spent in self-directed learning activities. Only 9% of the total on duty time was spent in the presence of patients. Sixty-five percent of communication time was devoted to information transfer. A total of 968 interruptions were recorded which took on average 93.5 seconds each to service. CONCLUSION: Detailed recording of residents' workflow is feasible and can now lead to the measurement of the effects of future changes to residency training. Education activities accounted for 13% of on-duty time.

Time-motion studies of internal medicine residents' duty hours: a systematic review and meta-analysis.

BACKGROUND: Since the mid-1980s, medical residents' long duty hours have been under scrutiny as a factor affecting patient safety and the work environment for the residents. After several mandated changes in duty hours, it is important to understand how residents spend their time before proposing and implementing future changes. Time-motion methodology may provide reliable information on what residents do while on duty. PURPOSE: The purpose of this study is to review all available literature pertaining to time-motion studies of internal medicine residents while on a medicine service and to understand how much of their time is apportioned to various categories of tasks, and also to determine the effects of the Accreditation Council for Graduate Medical Education (ACGME)-mandated duty hour changes on resident workflow in North America. METHODS: Electronic bibliographic databases were searched for articles in English between 1941 and April 2013 reporting time-motion studies of internal medicine residents rotating through a general medicine service. RESULTS: Eight articles were included. Residents spent 41.8% of time in patient care activities, 18.1% communicating, 13.8% in educational activities, 19.7% in personal/other, and 6.6% in transit. North American data showed the following changes after the implementation of the ACGME 2003 duty hours standard: patient care activities from 41.8% to 40.8%, communication activities from 19.0% to 22.3%, educational activities from 17.7% to 11.6%, and personal/other activities from 21.5% to 17.1%. CONCLUSION: There was a paucity of time-motion data. There was great variability in the operational definitions of task categories reported in the studies. Implementation of the ACGME duty hour standards did not have a significant effect on the percentage of time spent in particular tasks. There are conflicting reports on how duty hour changes have affected patient safety. A low proportion of time spent in educational activities deserves further study and may point to a review of the educational models used.

The influence of cholinesterase inhibitor therapy for dementia on risk of cardiac pacemaker insertion: a retrospective, population-based, health administrative databases study in Ontario, Canada.

BACKGROUND: Cholinesterase inhibitors are used to treat the symptoms of dementia and can theoretically cause bradycardia. Previous studies suggest that patients taking these medications have an increased risk of undergoing pacemaker insertion. Since these drugs have a marginal impact on patient outcomes, it might be preferable to change drug treatment rather than implant a pacemaker. This population-based study determined the association of people with dementia exposed to cholinesterase inhibitor medication and pacemaker insertion. METHODS: We used data from the Ontario health administrative databases from January 1, 1993 to June 30, 2012. We included all community-dwelling seniors who had a code for dementia and were exposed to cholinesterase inhibitors (donezepil, galantamine, and rivastigmine) and/or drugs used to treat co-morbidities of hypertension, diabetes, depression and hypothyroidism. We controlled for exposure to anti-arrhythmic drugs. Observation started at first exposure to any medication and continued until the earliest of pacemaker insertion, death, or end of study. RESULTS: 2,353,909 people were included with 96,000 (4.1%) undergoing pacemaker insertion during the observation period. Case-control analysis showed that pacemaker patients were less likely to be coded with dementia (unadjusted OR 0.42 [95%CI 0.41-0.42]) or exposed to cholinesterase inhibitors (unadjusted OR 0.39 [95%CI 0.37-0.41]). That Cohort analysis showed patients with dementia taking cholinesterase inhibitors had a decreased risk of pacemaker insertion (unadj-HR 0.58 [0.55-0.61]). Adjustment for patient age, sex, and other medications did not notably change results, as did restricting the analysis to incident users. CONCLUSIONS: Patients taking cholinesterase inhibitors rarely undergo, and have a significantly reduced risk of, cardiac pacemaker insertion.

Improved targeting of cancer care for older patients: a systematic review of the utility of comprehensive geriatric assessment.

A comprehensive geriatric assessment (CGA) provides clinicians with detailed information on a patient's physiological age and may aid in the treatment decision-making process. Conducting a CGA, however, is time-consuming, requiring extensive data collection and, in some cases, the involvement of multiple healthcare professionals. The CGA is also not specifically targeted towards assessing patients presenting with neoplastic pathologies. These limitations have precluded this tool's inclusion in routine oncologic practice involving seniors. In order to identify CGA domains most predictive of important cancer-specific outcomes, we conducted a systematic review (PROSPERO registration number CRD42012002476) using MEDLINE, CINAHL, EMBASE and CANCERLIT databases. Studies published in English or French between May 1997 and May 2012, in which a CGA was conducted in patients over the age of 65 initiating cancer treatment, were assessed for eligibility, of which 9 studies were selected for this review. As part of the inclusion criteria, all studies must have assessed, at minimum, the following domains: nutritional, cognitive and functional status, polypharmacy, comorbidities and the presence of geriatric syndromes. In predicting mortality, in at least one study or another, all of the aforementioned CGA domains were found to be significant. Most frequently, however, the following domains were reported for predicting mortality: nutritional status (HR=1.84-2.54), the presence of geriatric syndromes such as depression (HR=1.51-1.81), and functional status (HR=1.04-1.33). With regards to chemotherapy-related toxicity, similar findings were obtained where functional status (OR=1.71-2.47) and the presence of geriatric syndromes, such as impaired hearing (OR=1.67, 95% CI 1.04-2.69), had the most significant predictive value. Only one study reported on the incidence of post-operative complications for which severe comorbidity was found to be highly associated with experiencing severe complications (OR=5.62, 95% CI 2.18-14.50), while functional status was found to be significantly associated with experiencing any complication (OR=4.02, 95% CI 1.24-13.09).

Prescribing opioids in older people.

People are living to older age. Demographic pressures are driving change. Opiate analgesics are the most powerful known pain relievers. Persistent pain, both cancer and non-cancer types is frequent in older adults. The use of opioid analgesics is appropriate in the treatment of moderate to severe persistent pain. The challenge of prescribing opioids in older adults is to understand the factors involved in making appropriate choices and monitoring the beneficial effects of pain relief while managing the side-effects. This article will review the current concepts, evidence and controversies surrounding opiate use in the elderly. An approach is outlined which involves: pain assessment, screening for substance abuse potential, deciding whether you are able to treat your patient without help, starting treatment, monitoring effectiveness of pain control and managing opioid-associated side-effects. The goal of pain management using opioids is the attainment of improved function and quality of life.

Using novel Canadian resources to improve medication reconciliation at discharge: study protocol for a randomized controlled trial.

BACKGROUND: Adverse drug events are responsible for up to 7% of all admissions to acute care hospitals. At least 58% of these are preventable, resulting from incomplete drug information, prescribing or dispensing errors, and overuse or underuse of medications. Effective implementation of medication reconciliation is considered essential to reduce preventable adverse drug events occurring at transitions between community and hospital care. An electronically enabled discharge reconciliation process represents an innovative approach to this problem. METHODS/DESIGN: Participants will be recruited in Quebec and are eligible for inclusion if they are using prescription medication at admission, covered by the Quebec drug insurance plan, admitted from the community, 18 years or older, admitted to a general or intensive care medical or surgical unit, and discharged alive. A sample size of 3,714 will be required to detect a 5% reduction in adverse drug events. The intervention will comprise electronic retrieval of the community drug list, combined with an electronic discharge reconciliation module and an electronic discharge communication module. The primary outcomes will be adverse drug events occurring 30 days post-discharge, identified by a combination of patient self-report and chart abstraction. All emergency room visits and hospital readmission during this period will be measured as secondary outcomes. A cluster randomization approach will be used to allocate 16 medical and 10 surgical units to electronic discharge reconciliation and communication versus usual care. An intention-to-treat approach will be used to analyse data. Logistic regression will be undertaken within a generalized estimating equation framework to account for clustering within units. DISCUSSION: The goal of this prospective trial is to determine if electronically enabled discharge reconciliation will reduce the risk of adverse drug events, emergency room visits and readmissions 30 days post-discharge compared with usual care. We expect that this intervention will improve adherence to medication reconciliation at discharge, the accuracy of the community-based drug history and effective communication of hospital-based treatment changes to community care providers. The results may support policy-directed investments in computerizing and training of hospital staff, generate key requirements for future hospital accreditation standards, and highlight functional requirements for software vendors.

Medication-related falls in the elderly: causative factors and preventive strategies.

People are living to older age. Falls constitute a leading cause of injuries, hospitalization and deaths among the elderly. Older people fall more often for a variety of reasons: alterations in physiology and physical functioning, and the use (and misuse) of medications needed to manage their multiple conditions. Pharmacological factors that place the elderly at greater risk of drug-related side effects include changes in body composition, serum albumin, total body water, and hepatic and renal functioning. Drug use is one of the most modifiable risk factors for falls and falls-related injuries. Fall-risk increasing drugs (FRIDs) include drugs for cardiovascular diseases (such as digoxin, type 1a anti-arrhythmics and diuretics), benzodiazepines, antidepressants, antiepileptics, antipsychotics, antiparkinsonian drugs, opioids and urological spasmolytics. Psychotropic and benzodiazepine drug use is most consistently associated with falls. Despite the promise of a more favourable side-effect profile, evidence shows that atypical antipsychotic medications and selective serotonin reuptake inhibitor antidepressants do not reduce the risk of falls and hip fractures. Despite multiple efforts with regards to managing medication-associated falls, there is no clear evidence for an effective intervention. Stopping or lowering the dose of psychotropic drugs and benzodiazepines does work, but ensuring a patient remains off these drugs is a challenge. Computer-assisted alerts coupled with electronic prescribing tools are a promising approach to lowering the risk of falls as the use of information technologies expands within healthcare.

Moving Towards the Age-friendly Hospital: A Paradigm Shift for the Hospital-based Care of the Elderly.

INTRODUCTION: Care of the older adult in the acute care hospital is becoming more challenging. Patients 65 years and older account for 35% of hospital discharges and 45% of hospital days. Up to one-third of the hospitalized frail elderly loses independent functioning in one or more activities of daily living as a result of the 'hostile environment' that is present in the acute hospitals. A critical deficit of health care workers with expertise and experience in the care of the elderly also jeopardizes successful care delivery in the acute hospital setting. METHODS: We propose a paradigm shift in the culture and practice of event-driven acute hospital-based care of the elderly which we call the Age-friendly Hospital concept. Guiding principles include: a favourable physical environment; zero tolerance for ageism throughout the organization; an integrated process to develop comprehensive services using the geriatric approach; assistance with appropriateness decision-making and fostering links between the hospital and the community. Our current proposed strategy is to focus on delirium management as a hospital-wide condition that both requires and highlights the Geriatric Medicine specialist as an expert of content, for program development and of evaluation. CONCLUSION: The Age-friendly Hospital concept we propose may lead the way to enable hospitals in the fast-moving health care system to deliver high-quality care without jeopardizing risk-benefit, function, and quality of life balances for the frail elderly. Recruitment and retention of skilled health care professionals would benefit from this positive 'branding' of an institution. Convincing hospital management and managing change are significant challenges, especially with competing priorities in a fiscal environment with limited funding. The implementation of a hospital-wide delirium management program is an example of an intervention that embodies many of the principles in the Age-friendly Hospital concept. It is important to change the way hospital care is delivered to older adults in time to meet our needs when we need hospital services ourselves.

How can we improve targeting of frail elderly patients to a geriatric day-hospital rehabilitation program?

BACKGROUND: The optimal patient selection of frail elderly persons undergoing rehabilitation in Geriatric Day Hospital (GDH) programs remains uncertain. This study was done to identify potential predictors of rehabilitation outcomes for these patients. METHODS: This study is a retrospective cohort analysis of patients admitted to the rehabilitation program of our GDH, in Montreal, Canada, over a five year period. The measures considered were: Barthel Index, Older Americans Resources and Services, Folstein Mini Mental Status Exam, Timed Up & Go (TUG), 6-minute walk test (6 MWT), Gait speed, Berg Balance, grip strength and the European Quality of life - 5 Dimensions. Successful improvement with rehabilitation was defined as improvement in three or more tests of physical function. Logistic regression analysis using the Bayesian Information Criterion (BIC) was employed to select the optimal model for making predictions of rehabilitation success. RESULTS: A total of 335 patients were studied, but only 233 patients had a complete data set suitable for the predictive model. Average age was 81 years and patients attended the GDH an average of 24 visits. Significant changes were found in several measures of physical performance for many patients ranging from improved gait speed in 21.3% to improved TUG in 62.7% of the cohort. Fifty-eight percent of patients attained successful improvement with rehabilitation by our criteria. This group was characterized by lower test scores on admission. Using BIC, the best predictor model was the 6 MWT [OR: 0.994 per meter walked (95% CI: 0.990-0.997)]. CONCLUSIONS: The GDH rehabilitation program is effective in improving patients' physical performance. Although no single measure was found to be sufficiently predictive to help target candidates appropriately, the 6 MWT showed a trend to significance. Further research will be done to elucidate the utility of a composite 'rehab appropriateness index' and the role of International Classification of Function concepts for targeting frail elderly to GDH rehabilitation services.
