Evaluating an inpatient deprescribing initiative at a rural community hospital in Ontario.

BACKGROUND: Deprescribing is an effective means to reduce polypharmacy in elderly patients. However, geriatric day care deprescribing services are challenging to implement in rural regions. In this study, we examined whether a subacute care unit of a rural hospital could deliver a comprehensive and multidisciplinary intervention to promote deprescribing in patients and whether this intervention would succeed in achieving significant and lasting deprescribing results. METHODS: We conducted a cross-sectional analysis of a deprescribing program at a rural hospital in Eastern Ontario, Canada. Participants were 11 patients, aged 65 or older, who were admitted to the hospital's medical/surgical unit or who presented to the emergency department. Clinicians followed a structured, comprehensive and multidisciplinary approach designed to facilitate deprescribing, which concluded with an outcome evaluation at discharge and follow-up phone calls. Outcomes included the frequency and total number of medications successfully removed, reduced, substituted and restarted after discharge and emergency department visits and hospitalizations 6 months before and after the intervention. RESULTS: Of a total 57 deprescribed medications, 38 were eliminated, 8 were switched to a safer alternative, and 11 were dose reduced. Postdischarge deprescribing reversal occurred in only 5 of 57 deprescribed medications. Among the study population, a 59.2% reduction was observed in the combined number of emergency department visits and hospitalizations 6 months after deprescribing. CONCLUSIONS: This feasibility study was successful in showing the potential added value for offering a rehabilitative, subacute care, inpatient, comprehensive and multidisciplinary approach toward patients with complex deprescribing needs. It also showed proof of concept in reducing polypharmacy-induced adverse health outcomes. Can Pharm J (Ott) 2020:153:xx-xx.

Risk of Arterial and Venous Thrombotic Events Among Patients with COVID-19: A Multi-National Collaboration of Regulatory Agencies from Canada, Europe, and United States.

Purpose: Few studies have examined how the absolute risk of thromboembolism with COVID-19 has evolved over time across different countries. Researchers from the European Medicines Agency, Health Canada, and the United States (US) Food and Drug Administration established a collaboration to evaluate the absolute risk of arterial (ATE) and venous thromboembolism (VTE) in the 90 days after diagnosis of COVID-19 in the ambulatory (eg, outpatient, emergency department, nursing facility) setting from seven countries across North America (Canada, US) and Europe (England, Germany, Italy, Netherlands, and Spain) within periods before and during COVID-19 vaccine availability. Patients and Methods: We conducted cohort studies of patients initially diagnosed with COVID-19 in the ambulatory setting from the seven specified countries. Patients were followed for 90 days after COVID-19 diagnosis. The primary outcomes were ATE and VTE over 90 days from diagnosis date. We measured country-level estimates of 90-day absolute risk (with 95% confidence intervals) of ATE and VTE. Results: The seven cohorts included 1,061,565 patients initially diagnosed with COVID-19 in the ambulatory setting before COVID-19 vaccines were available (through November 2020). The 90-day absolute risk of ATE during this period ranged from 0.11% (0.09-0.13%) in Canada to 1.01% (0.97-1.05%) in the US, and the 90-day absolute risk of VTE ranged from 0.23% (0.21-0.26%) in Canada to 0.84% (0.80-0.89%) in England. The seven cohorts included 3,544,062 patients with COVID-19 during vaccine availability (beginning December 2020). The 90-day absolute risk of ATE during this period ranged from 0.06% (0.06-0.07%) in England to 1.04% (1.01-1.06%) in the US, and the 90-day absolute risk of VTE ranged from 0.25% (0.24-0.26%) in England to 1.02% (0.99-1.04%) in the US. Conclusion: There was heterogeneity by country in 90-day absolute risk of ATE and VTE after ambulatory COVID-19 diagnosis both before and during COVID-19 vaccine availability.

Improving urinary catheterisation practices in a rural hospital in Ontario.

INTRODUCTION: A urinary catheter constitutes a one-point patient restraint, can induce deconditioning and may lead to patient mortality. An audit performed at Winchester District Memorial Hospital revealed that 20% of patients had a urinary catheter, of whom 31% did not meet the criteria for catheterisation. The main objective of this study was to use the Influencer Change Model and the Choosing Wisely Canada toolkit to create a bundle of interventions that would reduce the unnecessary use of urinary catheters in hospitalised patients. METHODS: In a rural teaching hospital, a time-series quasi-experiment was employed to decrease inappropriate use of urinary catheters. Both the Choosing Wisely Canada toolkit for appropriate use of urinary catheters and the Influencer change management approach were used to create effective interventions. RESULTS: This study revealed that there was no improvement in appropriate urinary catheter use during Plan-Do-Study-Act (PDSA) cycle 1. There was gradual improvement during PDSA cycle 2, with the percentage of inappropriate urinary catheter use dropping from an initial 31% before any interventions to less than 5% by the end of this study. DISCUSSION/CONCLUSION: This study aimed to reduce the inappropriate use of urinary catheters in a rural hospital with limited resources. The findings indicate that by using a change model, such as the Influencer Change Model, it is possible to promote better patient care through empowering healthcare staff to implement accepted protocols more stringently and thereby to decrease the inappropriate use of urinary catheters to 0%.

Using policy simulation to predict drug plan expenditure when planning reimbursement changes.

BACKGROUND: Drug plan decision makers need accurate financial impact projections before the implementation of new drug policy initiatives. Tools for such projections need to have small margins of error and be based on methodology that is easy to communicate to stakeholders. Ad hoc methods typically used for financial impact projections by health plans are inadequate. OBJECTIVE: To present a flexible tool for projecting the financial impact of drug policy changes based on historical dispensing data and simulation, and explore its validity using a recent example of a complex drug policy change in British Columbia, Canada. METHODS: A policy simulator (SAS) program using a Web browser interface) was used to produce 3-year forecasts of expenditure (for the drug plan and for individual families) along with the number of patients who would pay more or less for their drugs (stratified by age and income level) for various proposed drug policies starting in 2003. Drug expenditure under each policy was simulated based on projections from prescription claim records of the British Columbia PharmaNet database of community pharmacy prescriptions from 1 January 2001 to 31 December 2001. The simulator selected a random 1% sample of British Columbia families (175,000 families) in the database. Once the new drug policy was selected and implemented, the accuracy of the predictions were tested by comparing the actual PharmaCare expenditure for the period 1 May 2003 to 31 March 2004 after implementation of the new drug policy with the final simulation made for this policy in February 2003, 2 months before the policy was implemented. RESULTS: The policy simulation tool produced hundreds of variations for decision makers in the months before the final policy rules were decided upon. When compared with actual drug expenditure after policy implementation, it was found that the tool had predicted spending with <1% error for the first 11 months after introduction of the policy. As well as producing accurate expenditure forecasts for the insurer, the tool was able to predict how family out-of-pocket expenditure would be affected. CONCLUSIONS: The simulator aided drug policy planning and communication. The tool provided rapid and accurate results that were communicated easily to decision makers. Such policy simulation can be applied to a wide range of health plans and policy changes.

Financing the Health Care System: is Long-term Sustainability Possible?

The report analyzes three indicators of sustainability: the ratio of total health care spending to Gross Domestic Product (GDP), the ratio of public spending on health care to GDP and the ratio of government health expenditures to total government revenue. The Analysis of Health Care Expenditures focuses on expenditures for health care as a determinate of sustainability. The first part looks at historical trends in spending, followed by estimated cost drivers and the expected influence these will have on total health care spending. Finally, financing options will be reviewed for their impact on public spending. In a recent paper Ruggeri (2006) analysed sustainability of health care. He suggests there are several indicators of sustainability with three being the most useful: 1 The ratio of total health care spending to GDP. 2 The ratio of public spending on health care to GDP. 3 The ratio of government health expenditures to total government revenue. These indicators provide a framework to determine sustainability using additional data to the original Ruggeri study. The chosen indicators are important because they can be used to refute claims by opponents of the public health care system that it is in fiscal crisis
