Increased Virtual Visits to Physicians During the COVID-19 Pandemic and Estimated Impact on Physician Compensation: The Case of Lung and Colorectal Cancers, Chronic Obstructive Pulmonary Diseases, and Heart Failure in Alberta, Canada.

Introduction: The COVID-19 pandemic started in Alberta in March 2020 and significantly increased telehealth service use and provision reducing the risk of virus transmission. We examined the change in the number and proportion of virtual visits by physician specialty and condition (chronic obstructive pulmonary diseases [COPD], heart failure [HF], colorectal and lung cancers), as well as associated changes in physician compensation. Methods: A population-based design was used to analyze all processed physician claims comparing the number and proportion of virtual visits and associated physician billings relative to in-person between pre- (2019/2020) and intra-pandemic (2020/2021). Physician compensations were the claim amounts paid by the health insurance. Results: Pre-pandemic (intra-), there were 8,981 (8,897) lung cancer, 9,245 (9,029) colorectal, 37,558 (36,292) HF, and 68,270 (52,308) COPD patients. Each patient had totally 2.3-4.7 (of which 0.4-0.6% were virtual) general practitioner (GP) visits and 0.9-2.3 (0.2-0.7% were virtual) specialist visits per year pre-pandemic. The average number and proportion of per-patient virtual visits to GPs and specialists grew significantly pre- to intra-pandemic by 2,138-4,567%, and 2,201-7,104%, respectively. Given the lower fees of virtual compared with in-person visits, the reduction in physician compensation associated with the increased use of virtual care was estimated at $3.85 million, with $2.44 million attributed to specialist and $1.41 million to GP. Discussion: Utilization of telehealth increased significantly, while the physician billings per patient and physician compensation declined early in the pandemic in Alberta for the four chronic diseases considered. This study forms the basis for future study in understanding the impact of virtual care, now part of the fabric of health care delivery, on quality of care and patient safety, overall health service utilization (such as diagnostic imaging and other investigations), as well as economic impacts to patients, health care systems, and society.

Treated versus self-reported prevalence of chronic pain and costs of patients' health services utilization: a population-based study of health administrative databases.

Objectives: To compare treated to self-reported prevalence of chronic pain (CP) and to estimate health services utilization (HSU) costs of patients treated for CP in Alberta, Canada. Methods: Patients treated for CP were identified by the physician billing codes of health services for CP from the practitioner claims database in fiscal year 2021/22. The treated prevalence of CP (number of these patients divided by the population) was compared to the self-reported prevalence of CP previously estimated (doi:10.1371/journal.pone.0272638). Costs of patients' HSU included costs for general practitioner (GP), specialist, inpatient, emergency department, outpatient clinic services, and prescription drugs. Results: The treated prevalence of CP was 6.0% (4.4% among males and 7.8% among females) which was 30% to 41% of the self-reported prevalence. The highest treated prevalence (7.2%) was found in the age group of 18-64 years, followed by age groups of >64 years (7.0%) and <18 years (2.1%). The average cost per patient per year was $5096 ($5878 for males and $4652 for females), of which hospitalizations accounted for 65.0%, outpatient clinic visits 16.4%, ED visits 9.5%, prescription drugs 4.7%, GP visits 3.9%, and specialist visits 0.4%. The total cost of patients with CP for the health system was $1.37 billion (∼7% of total health expenditure), of which males accounted for 41.7% and females for 58.3%. Discussion: Our findings suggest that the economic burden of CP is considerable and that many people with self-reported CP do not use the public healthcare services. This can be multifactorial, including lack of availability and accessibility of publicly funded services, people's lack of awareness of available services, lower utilization due to COVID-19 pandemic, and reliance on self-management, private services, and alternative treatments. Further studies are warranted to inform future policies and health system initiatives aiming to reduce the burden of CP and improve lives of people living with it.

A Systems-Level Evaluation Framework for Virtual Care.

The virtual care landscape is significantly changing, largely due to an increased demand initiated by the COVID-19 pandemic and the evolution of technology. Complex questions about how to best leverage virtual care and its impact remain unanswered. Our team developed a systems-level evaluation framework to inform virtual care service design and evaluation to take a more comprehensive approach to planning and implementing virtual care. We designed the framework for application in Alberta Health Services (AHS) by engaging virtual care users (patients, families and healthcare providers), implementation staff and decision makers across the organization. Here we report our design process and key lessons learned. The framework received endorsement by AHS senior leadership for application across the system. Our next step is to test the framework. By sharing our design process and experiences, we aim to help inform other national and international jurisdictions plan virtual care evaluations within their context.

Understanding the chronic pain journey and coping strategies that patients use to manage their chronic pain: a qualitative, patient-led, Canadian study.

OBJECTIVE: To gain an insight into coping strategies that people living with chronic pain use to self-manage their pain. DESIGN: This qualitative Patient-oriented Research study used the Patient and Community Engagement Research approach. It was conducted by people with chronic pain lived experience, ensuring that patient perspective and needs were considered and addressed throughout the research cycle. Purposeful sampling was used for recruiting individuals living with chronic pain. A focus group and one-on-one semi-structured interviews were conducted via videoconference. The data were analysed iteratively using inductive thematic analysis and narrative story analysis. SETTING: Calgary, Alberta, Canada. PARTICIPANTS: Eleven adult participants, between the ages of 18 and 65, who self-identified as living with chronic pain for greater than 2 years. RESULTS: Three main themes emerged from the data: (1) the elements of chronic pain, (2) the chronic pain journey to acceptance and (3) daily coping strategies for chronic pain. Participants thought it was important to discuss these three themes because the daily coping strategies that they employed at any given time (theme 3) depended on the factors discussed in themes 1 and 2. Overlaying all of this is also a grieving process that people living with chronic pain may have to go through more than once. Participants also identified recommendations for healthcare professionals to support people living with chronic pain. CONCLUSIONS: Dealing with chronic pain affects all aspects of a person's life and involves a grieving process. When treating patients with chronic pain, it is important for healthcare professionals to understand the journey that people living with chronic pain go through, not just coping strategies. Diagnosis is critical for a patient's acceptance and in helping them find their new normal where they can employ daily coping strategies to manage their pain.

Opioid prescriptions and patients' health services utilization and cost before and during the COVID-19 pandemic: an exploratory population-based administrative data analysis.

The objective was to explore percentages of the population treated with prescribed opioids and costs of opioid-related hospitalizations and emergency department (ED) visits among individuals treated with prescription opioids and costs of all opioid-related hospitalizations and ED visits in the province (i.e., provincial costs) before and during the coronavirus disease 2019 (COVID-19) pandemic in Alberta, Canada. In administrative data, we identified individuals treated with prescription opioids and opioid-related hospitalizations and ED visits among those individuals and among all individuals in the province between 2015/16 and 2021/22 fiscal years. Services used were counted on an item-by-item basis and costed using case-mix approaches. Annually, from 9.98% (2020/21-2021/22) to 14.52% (2017/18) of the provincial population was treated with prescription opioids. Between 2015/16 and 2021/22, annual costs of opioid-related hospitalizations and ED visits among individuals treated with prescription opioids were ∼$5 and ∼$2 million, respectively. In 2020/21-2021/22, the provincial costs of opioid-related hospitalizations (∼$14 million) and ED visits (∼$7.0 million) were almost twice the costs observed in 2015/16 and immediately before the pandemic (2019/20). Our findings suggest that increases in the opioid-related utilization of inpatient and ED services between 2015/16 and 2021/22, including the drastic increases observed during the COVID-19 pandemic, were likely driven by unregulated substances.

Co-developing patient and family engagement indicators for health system improvement with healthcare system stakeholders: a consensus study.

OBJECTIVE: To develop a set of patient and family engagement indicators (PFE-Is) for measuring engagement in health system improvement for a Canadian provincial health delivery system through an evidence-based consensus approach. DESIGN: This mixed-method, multiphase project included: (1) identification of existing measures of patient and family engagement through a review of the literature and consultations with a diverse provincial council of patients, caregivers, community members and researchers. The Public and Patient Engagement Evaluation Tool (PPEET) was selected; (2) consultations on relevance, acceptability and importance with patient and family advisors, and staff members of Alberta Health Services' Strategic Clinical Networks. This phase included surveys and one-on-one semi-structured interviews aimed to further explore the use of PPEET in this context. Findings from the survey and interviews informed the development of PFE-Is; (3) a Delphi consensus process using a modified RAND/UCLA Appropriateness Method to identify and refine a core set of PFE-Is. PARTICIPANTS: The consensus panel consisted of patients, family members, community representatives, clinicians, researchers and healthcare leadership. RESULTS: From an initial list of 33 evidence-based PFE-Is identified, the consensus process yielded 18 final indicators. These PFE-Is were grouped into seven themes: communication, comfort to contribute, support needed for engagement, impact and influence of engagement initiative, diversity of perspectives, respectful engagement, and working together indicators. CONCLUSIONS: This group of final patient, family and health system leaders informed indicators can be used to measure and evaluate meaningful engagement in health research and system transformation. The use of these metrics can help to improve the quality of patient and family engagement to drive health research and system transformation.

Creating Value Through Learning Health Systems: The Alberta Strategic Clinical Network Experience.

Design, implementation, and evaluation of effective multicomponent interventions typically take decades before value is realized even when value can be measured. Value-based health care, an approach to improving patient and health system outcomes, is a way of organizing health systems to transform outcomes and achieve the highest quality of care and the best possible outcomes with the lowest cost. We describe 2 case studies of value-based health care optimized through a learning health system framework that includes Strategic Clinical Networks. Both cases demonstrate the acceleration of evidence to practice through scientific, financial, structural administrative supports and partnerships. Clinical practice interventions in both cases, one in perioperative services and the other in neonatal intensive care, were implemented across multiple hospital sites. The practical application of using an innovation pipeline as a structural process is described and applied to these cases. A value for money improvement calculator using a benefits realization approach is presented as a mechanism/tool for attributing value to improvement initiatives that takes advantage of available system data, customizing and making the data usable for frontline managers and decision makers. Health care leaders will find value in the descriptions and practical information provided.

Delivery and Prioritization of Surgical Care in Canada During COVID-19: An Environmental Scan.

BACKGROUND: During COVID-19 healthcare systems had to make concessions to make room for the surge of COVID-19 patients requiring hospital and intensive care. Postponing surgeries was a common strategy; however, it is unclear how surgical care was delivered during this time of constraint. The objective of this study was to understand how surgical care was delivered and prioritized during the COVID-19 pandemic response. METHODS: This was an environmental scan following the Canadian Agency for Drugs and Technologies in Health methodology. This study was conducted in Canada; a universal, publicly funded healthcare system. Evidence sources on policies pertaining to the provision of surgical care between January 2020 and October 2022 were obtained from ministries of health, health services agencies and publicly funded hospitals across all 10 provinces and three territories. We synthesized the evidence sources using framework analysis. RESULTS: We identified 205 evidence sources that described six themes about the provision of surgical care during the COVID-19 pandemic: the cycle of postponement and resumption; guidelines for triaging and prioritizing surgical cases; Infection Prevention and Control (IPAC), and safety measures for surgical care during COVID-19, patient-centred care, and looking forward (recovery planning, leadership, and decision-making). CONCLUSION: This study provides a comprehensive understanding of how surgical care was disrupted and innovated during COVID-19 which can inform future strategies for providing effective and efficient surgical care during times of healthcare constraint.

Strategic Clinical Network Teams Improve Effectiveness, Team and Leadership Processes and Inputs: Theory-Based Longitudinal Survey.

Strategic Clinical Networks (SCNs) in Alberta include multidisciplinary teams that work toward health system innovation and improvement; however, what contributes to team effectiveness is unclear. This theory-informed longitudinal survey (n = 826) evaluated team effectiveness within SCNs and predictors of effectiveness. Satisfaction, inter-team relationships and seven predictors including team inputs and team and leadership processes improved over two years. Attitudinal outputs were predicted by the same factors over time, whereas performance outputs were predicted by different factors. This innovative study emphasizes that SCN teams and their effectiveness evolve over time and that team-based research can refine network evaluations.

Economic burden of chronic pain in Alberta, Canada.

BACKGROUND: Although chronic pain (CP) is common, little is known about its economic burden in Alberta, Canada. AIMS: To estimate incremental (as compared to the general population or people without CP) societal (healthcare and lost productivity) costs of CP in Alberta. METHODS: We applied the prevalence estimated from the Canadian Community Health Survey data to the population retrieved from the Statistics Canada to estimate the number of people with CP in Alberta in 2019. We analyzed the Alberta Health administrative databases to estimate the healthcare costs of person with CP. Finally, we multiplied the number of people with the cost per person. RESULTS: The prevalence of any CP was 20.1% and of activity-preventing CP was 14.5% among people aged > = 12 years. Incremental cost per person with CP per year was CA$2,217 for healthcare services (among people aged > = 12 years) and CA$8,412 for productivity losses (among people aged 18-64 years). Of the healthcare cost, prescription drugs accounted for the largest share (32.8%), followed by inpatient services (31.0%), outpatient services (13.1%), physician services (9.8%), other services (7.4%), and diagnostic imaging (5.8%). Provincially, total incremental cost of CP ranges from CA$1.2 to 1.7 billion for healthcare services (6% to 8% of total provincial health expenditure); and CA$3.4 to 4.7 billion for productivity losses. Considering costs for long-term care services, the total societal cost of CP in Alberta was CA$6.3 to 8.3 billion per year, reflecting 2.0% to 2.7% of Alberta's GDP. CONCLUSIONS: Interventions improving CP prevention and management to reduce this substantial economic burden are urgently needed.

Avoidable intensive care unit resource use and costs of unvaccinated patients with COVID-19: a historical population-based cohort study.

PURPOSE: SARS-CoV-2 vaccines have been proven effective at preventing poor outcomes from COVID-19; however, voluntary vaccination rates have been suboptimal. We assessed the potential avoidable intensive care unit (ICU) resource use and associated costs had unvaccinated or partially vaccinated patients hospitalized with COVID-19 been fully vaccinated. METHODS: We conducted a retrospective, population-based cohort study of persons aged 12 yr or greater in Alberta (2021 population ~ 4.4 million) admitted to any ICU with COVID-19 from 6 September 2021 to 4 January 2022. We used publicly available aggregate data on COVID-19 infections, vaccination status, and health services use. Intensive care unit admissions, bed-days, lengths of stay, and costs were estimated for patients with COVID-19 and stratified by vaccination status. RESULTS: In total, 1,053 patients admitted to the ICU with COVID-19 were unvaccinated, 42 were partially vaccinated, and 173 were fully vaccinated (cumulative incidence 230.6, 30.8, and 5.5 patients/100,000 population, respectively). Cumulative incidence rate ratios of ICU admission were 42.2 (95% confidence interval [CI], 39.7 to 44.9) for unvaccinated patients and 5.6 (95% CI, 4.1 to 7.6) for partially vaccinated patients when compared with fully vaccinated patients. During the study period, 1,028 avoidable ICU admissions and 13,015 bed-days were recorded for unvaccinated patients and the total avoidable costs were CAD 61.3 million. The largest opportunity to avoid ICU bed-days and costs was in unvaccinated patients aged 50 to 69 yr. CONCLUSIONS: Unvaccinated patients with COVID-19 had substantially greater rates of ICU admissions, ICU bed-days, and ICU-related costs than vaccinated patients did. This increased resource use would have been potentially avoidable had these unvaccinated patients been vaccinated against SARS-CoV-2.

RéSUMé: OBJECTIF: Les vaccins contre le SRAS-CoV-2 se sont avérés efficaces pour prévenir les devenirs défavorables associés à la COVID-19; toutefois, les taux de vaccination volontaire ont été sous-optimaux. Nous avons évalué l'utilisation potentiellement évitable des ressources des unités de soins intensifs (USI) et les coûts associés si les patients non vaccinés ou partiellement vaccinés qui ont dû être hospitalisés pour la COVID-19 avaient été complètement vaccinés. MéTHODE: Nous avons réalisé une étude de cohorte rétrospective basée sur la population de personnes âgées de 12 ans ou plus en Alberta (population de 2021 ~ 4,4 millions) admises dans une unité de soins intensifs et atteintes de COVID-19 du 6 septembre 2021 au 4 janvier 2022. Nous avons utilisé des données agrégées accessibles au public sur les infections à la COVID-19, le statut vaccinal et l'utilisation des services de santé. Les admissions aux soins intensifs, les journées-patients, les durées de séjour et les coûts ont été estimés pour les patients atteints de la COVID-19 et stratifiés selon le statut vaccinal. RéSULTATS: Au total, 1053 patients admis à l'USI souffrant de la COVID-19 n'étaient pas vaccinés, 42 étaient partiellement vaccinés et 173 étaient complètement vaccinés (incidence cumulative 230,6, 30,8 et 5,5 patients / 100 000 habitants, respectivement). Les taux d'incidence cumulés des admissions aux soins intensifs étaient de 42,2 (intervalle de confiance [IC] à 95 %, 39,7 à 44,9) pour les patients non vaccinés et de 5,6 (IC 95 %, 4,1 à 7,6) pour les patients partiellement vaccinés par rapport aux patients entièrement vaccinés. Au cours de la période à l'étude, 1028 admissions évitables aux soins intensifs et 13 015 journées-patients ont été enregistrées pour les patients non vaccinés, et les coûts totaux évitables étaient de 61,3 millions de dollars canadiens. L'économie potentielle la plus importante en matière de journées-patients et de coûts en soins intensifs touchait les patients non vaccinés âgés de 50 à 69 ans. CONCLUSION: Les patients non vaccinés atteints de COVID-19 ont affiché des taux beaucoup plus élevés d'admissions à l'USI, de journées-patients à l'USI et de coûts liés à l'USI que les patients vaccinés. Cette utilisation accrue des ressources aurait été potentiellement évitable si ces patients non vaccinés avaient été vaccinés contre le SRAS-CoV-2.

Expected Cost Savings From Low-Dose Computed Tomography Scan Screening for Lung Cancer in Alberta, Canada.

Introduction: The expensive modern therapeutic regimens for advanced lung cancer (LC) stages have been recently approved. We evaluated whether low-dose computed tomography (LDCT) LC screening of high-risk Albertans is cost saving. Methods: We used a decision analytical modeling technique with a health system perspective and a time horizon of 3 years to compare benefits associated with reduced health service utilization (HSU) from earlier diagnosis to the costs of screening. Using patient-level data, HSU costs by stage of disease were estimated for patients with LC, including inpatient, outpatient, and physician services, and costs for prescription drugs and cancer treatments. Results: Of 101,000 people aged 55 to 74 years eligible for screening, an estimated 88,476 scans would be performed in Alberta in 3 years. Given LDCT sensitivity and specificity of 90.5% and 93.1%, respectively, we estimated that a stage shift toward earlier diagnosis would be expected whereby 43% more patients would be identified at stage 1 or 2 as compared with without screening. The estimated cost of screening is $35.6 million (M), whereas the stage shift associated with screening would avoid $42M in HSU costs. The net cost avoidance associated with screening is therefore $6.65M. The probability for the screening to be cost saving is estimated at 72%. Conclusions: This study has revealed that LDCT LC screening is likely to be cost saving in Alberta. Adoption of this program into the provincial health care system is worth considering provided constraints in the system related to surgical capacity and CT wait times could be addressed.

Association Between Pandemic Coronavirus Disease 2019 Public Health Measures and Reduction in Critical Care Utilization Across ICUs in Alberta, Canada.

OBJECTIVES: The coronavirus disease 2019 pandemic has disrupted critical care services across the world. In anticipation of surges in the need for critical care services, governments implemented "lockdown" measures to preserve and create added critical care capacity. Herein, we describe the impact of lockdown measures on the utilization of critical care services and patient outcomes compared with nonlockdown epochs in a large integrated health region. DESIGN: This was a population-based retrospective cohort study. SETTING: Seventeen adult ICUs across 14 acute care hospitals in Alberta, Canada. PATIENTS: All adult (age ≥ 15 yr) patients admitted to any study ICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The main exposure was ICU admission during "lockdown" occurring between March 16, 2020, and June 30, 2020. This period was compared with two nonpandemic control periods: "year prior" (March 16, 2019, to June 30, 2019) and "pre lockdown" immediately prior (November 30, 2019, to March 15, 2020). The primary outcome was the number of ICU admissions. Secondary outcomes included the following: daily measures of ICU utilization, ICU duration of stay, avoidable delay in ICU discharge, and occupancy; and patient outcomes. Mixed multilevel negative binomial regression and interrupted time series regression were used to compare rates of ICU admissions between periods. Multivariable regressions were used to compare patient outcomes between periods. During the lockdown, there were 3,649 ICU admissions (34.1 [8.0] ICU admissions/d), compared with 4,125 (38.6 [9.3]) during the prelockdown period and 3,919 (36.6 [8.7]) during the year prior. Mean bed occupancy declined significantly during the lockdown compared with the nonpandemic periods (78.7%, 95.9%, and 96.4%; p < 0.001). Avoidable ICU discharge delay also decreased significantly (42.0%, 53.2%, and 58.3%; p < 0.001). During the lockdown, patients were younger, had fewer comorbid diseases, had higher acuity, and were more likely to be medical admissions compared with the nonpandemic periods. Adjusted ICU and hospital mortality and ICU and hospital lengths of stay were significantly lower during the lockdown compared with nonpandemic periods. CONCLUSIONS: The coronavirus disease 2019 lockdown resulted in substantial changes to ICU utilization, including a reduction in admissions, occupancy, patient lengths of stay, and mortality.

Return on Investment in Endovascular Care: The Case of Endovascular Reperfusion Alberta.

OBJECTIVE: We examined the return on investment (ROI) from the Endovascular Reperfusion Alberta (ERA) project, a provincially funded population-wide strategy to improve access to endovascular therapy (EVT), to inform policy regarding sustainability. METHODS: We calculated net benefit (NB) as benefit minus cost and ROI as benefit divided by cost. Patients treated with EVT and their controls were identified from the ESCAPE trial. Using the provincial administrative databases, their health services utilization (HSU), including inpatient, outpatient, physician, long-term care services, and prescription drugs, were compared. This benefit was then extrapolated to the number of patients receiving EVT increased in 2018 and 2019 by the ERA implementation. We used three time horizons, including short (90 days), medium (1 year), and long-term (5 years). RESULTS: EVT was associated with a reduced gross HSU cost for all the three time horizons. Given the total costs of ERA were $2.04 million in 2018 ($11,860/patient) and $3.73 million in 2019 ($17,070/patient), NB per patient in 2018 (2019) was estimated at -$7,313 (-$12,524), $54,592 ($49,381), and $47,070 ($41,859) for short, medium, and long-term time horizons, respectively. Total NB for the province in 2018 (2019) were -$1.26 (-$2.74), $9.40 ($10.78), and $8.11 ($9.14) million; ROI ratios were 0.4 (0.3), 5.6 (3.9) and 5.0 (3.5). Probabilities of ERA being cost saving were 39% (31%), 97% (96%), and 94% (91%), for short, medium, and long-term time horizons, respectively. CONCLUSION: The ERA program was cost saving in the medium and long-term time horizons. Results emphasized the importance of considering a broad range of HSU and long-term impact to capture the full ROI.

Exploring patient centredness, communication and shared decision-making under a new model of care: Community rehabilitation in canada.

Patient-centred care and patient engagement in healthcare and health research are widely mandated by funders, health systems and institutions. Increasingly, shared decision-making (SDM) is recognised as promoting patient-centred care. We explore this relationship by studying SDM in the context of integrating novel patient-centred policies in community rehabilitation. There is little research on SDM in rehabilitation, and less so in the critical community context. Patient co-investigators led study co-design. We aimed to describe how patients and providers experience SDM at community rehabilitation sites that adopted a novel, patient-centred Rehabilitation Model of Care (RMoC). Guided by focused ethnography, we conducted focus groups and interviews. Patient and professional participants were recruited from 10 RMoC early-adopter community rehabilitation sites. Sites varied in geography, patient population and provider disciplines. Patient and community engagement researchers used a set-collect-reflect method to document patient perspectives. Researchers captured provider perspectives using a semi-structured question guide. We completed 11 focus groups and 18 interviews (n = 45 providers, n = 17 patients). We found that most early-adopter providers spoke in a shared, patient-first language that focused on patient readiness, barriers and active listening. Congruent patient perceptions reflected inclusion in decision-making, goal setting and positive relationships. Many patients queried how care would become and remain accessible before and after community rehabilitation care respectively. Remaining connected while in the community was described as important to patients. Providers identified barriers like time, team dynamics and lack of clarity on the RMoC aims, which challenged the initiative's long-term sustainability. Policy innovations can promote SDM and communication through multiple strategies and training to facilitate candid, encouraging conversations. Sustainability of SDM gains is paramount. Most providers moved beyond tokenistic engagement, but competing responsibilities and team member resistance could thwart continuity. Further research is needed to empirically assess respectful and compassionate communication and SDM in community rehabilitation long term.

An Implementation Science Laboratory as One Approach to Whole System Improvement: A Canadian Healthcare Perspective.

Implementation science (IS) has emerged as an integral component for evidence-based whole system improvement. IS studies the best methods to promote the systematic uptake of evidence-based interventions into routine practice to improve the quality and effectiveness of health service delivery and patient care. IS laboratories (IS labs) are one mechanism to integrate implementation science as an evidence-based approach to whole system improvement and to support a learning health system. This paper aims to examine if IS labs are a suitable approach to whole system improvement. We retrospectively analyzed an existing IS lab (Alberta, Canada's Implementation Science Collaborative) to assess the potential of IS labs to perform as a whole system approach to improvement and to identify key activities and considerations for designing IS labs specifically to support learning health systems. Results from our evaluation show the extent to which IS labs support learning health systems through enabling infrastructures for system-wide improvement and research.

Patients' Use of Mobile Health for Self-management of Knee Osteoarthritis: Results of a 6-Week Pilot Study.

BACKGROUND: In a previous study, a prototype mobile health (mHealth) app was co-designed with patients, family physicians, and researchers to enhance self-management and optimize conservative management for patients with mild to moderate knee osteoarthritis (OA). OBJECTIVE: This study aims to evaluate the overall usability, quality, and effectiveness of the mHealth app prototype for aiding knee OA self-management from the perspectives of patients with OA and health care providers (HCPs). METHODS: Using methods triangulation of qualitative and quantitative data, we conducted a pilot evaluation of an mHealth app prototype that was codeveloped with patients and HCPs. We recruited adult patients aged ≥20 years with early knee OA (n=18) who experienced knee pain on most days of the month at any time in the past and HCPs (n=7) to participate. In the qualitative assessment, patient and HCP perspectives were elicited on the likeability and usefulness of app features and functionalities and the perceived impact of the app on patient-HCP communication. The quantitative assessment involved evaluating the app using usability, quality, and effectiveness metrics. Patient baseline assessments included a semistructured interview and survey to gather demographics and assess the quality of life (European Quality-of-Life 5-Dimension 5-Level Questionnaire [EQ-5D-5L]) and patient activation (patient activation measure [PAM]). Following the 6-week usability trial period, a follow-up survey assessed patients' perceptions of app usability and quality and longitudinal changes in quality of life and patient activation. Semistructured interviews and surveys were also conducted with HCPs (n=7) at baseline to evaluate the usability and quality of the app prototype. RESULTS: Interviews with patients and HCPs revealed overall positive impressions of the app prototype features and functionalities related to likeability and usefulness. Between the baseline and follow-up patient assessments, the mean EQ-5D-5L scores improved from 0.77 to 0.67 (P=.04), and PAM scores increased from 80.4 to 87.9 (P=.01). Following the 6-week evaluation, patients reported a mean System Usability Scale (SUS) score of 57.8, indicating marginal acceptability according to SUS cutoffs. The mean number of goals set during the usability period was 2.47 (SD 3.08), and the mean number of activities completed for knee OA self-management during the study period was 22.2 (SD 17.8). Spearman rank correlation (rs) calculations revealed that the follow-up PAM scores were weakly correlated (rs=-0.32) with the number of goals achieved and the number (rs=0.19) of activities performed during the 6-week usability period. HCPs reported a mean SUS score of 39.1, indicating unacceptable usability. CONCLUSIONS: This evidence-based and patient-centered app prototype represents a potential use of mHealth for improving outcomes and enhancing conservative care by promoting patient activation and patient-HCP communication regarding OA management. However, future iterations of the app prototype are required to address the limitations related to usability and quality.

Contextual factors and mechanisms that influence sustainability: a realist evaluation of two scaled, multi-component interventions.

BACKGROUND: In 2012, Alberta Health Services created Strategic Clinical NetworksTM (SCNs) to develop and implement evidence-informed, clinician-led and team-delivered health system improvement in Alberta, Canada. SCNs have had several provincial successes in improving health outcomes. Little research has been done on the sustainability of these evidence-based implementation efforts. METHODS: We conducted a qualitative realist evaluation using a case study approach to identify and explain the contextual factors and mechanisms perceived to influence the sustainability of two provincial SCN evidence-based interventions, a delirium intervention for Critical Care and an Appropriate Use of Antipsychotics (AUA) intervention for Senior's Health. The context (C) + mechanism (M) = outcome (O) configurations (CMOcs) heuristic guided our research. RESULTS: We conducted thirty realist interviews in two cases and found four important strategies that facilitated sustainability: Learning collaboratives, audit & feedback, the informal leadership role, and patient stories. These strategies triggered certain mechanisms such as sense-making, understanding value and impact of the intervention, empowerment, and motivation that increased the likelihood of sustainability. For example, informal leaders were often hands-on and influential to front-line staff. Learning collaboratives broke down professional and organizational silos and encouraged collective sharing and learning, motivating participants to continue with the intervention. Continual audit-feedback interventions motivated participants to want to perform and improve on a long-term basis, increasing the likelihood of sustainability of the two multi-component interventions. Patient stories demonstrated the interventions' impact on patient outcomes, motivating staff to want to continue doing the intervention, and increasing the likelihood of its sustainability. CONCLUSIONS: This research contributes to the field of implementation science, providing evidence on key strategies for sustainability and the underlying causal mechanisms of these strategies that increases the likelihood of sustainability. Identifying causal mechanisms provides evidence on the processes by which implementation strategies operate and lead to sustainability. Future work is needed to evaluate the impact of informal leadership, learning collaboratives, audit-feedback, and patient stories as strategies for sustainability, to generate better guidance on planning sustainable improvements with long term impact.

Evaluation of the Implementation of Multiple Enhanced Recovery After Surgery Pathways Across a Provincial Health Care System in Alberta, Canada.

Importance: Engaging multidisciplinary care teams in surgical practice is important for the improvement of surgical outcomes. Objective: To evaluate the association of multiple Enhanced Recovery After Surgery (ERAS) pathways with ERAS guideline adherence and outcomes. Design, Setting, and Participants: This quality improvement study compared a pre-ERAS cohort (2013-2017) with a post-ERAS cohort (2014-2018). All patients were from Alberta Health Services in Alberta, Canada, and had available ERAS and up to 1-year postsurgery administrative data. Data collected included age, sex, body mass index, tobacco and alcohol use, diabetes, comorbidity index, and surgical characteristics. Data analysis was performed from May 7, 2020, to February 1, 2021. Interventions: Implementation of 5 ERAS pathways (colorectal, liver, pancreas, gynecologic oncology, and radical cystectomy) across 9 sites. Main Outcomes and Measures: Adherence to ERAS guidelines was measured by the percentage of patients whose care met the common ERAS pathway care element criteria. Surgical procedures were grouped by complexity; complications were classified by severity. Outcome measures for the pre-post-ERAS cohorts included length of stay (LOS), readmission, complications, and mortality. Results: A total of 7757 patients participated in the study, including 984 in the pre-ERAS cohort (median [interquartile range] age, 62 [53-71] years; 526 [53.5%] female) and 6773 in the post-ERAS cohort (median [interquartile range] age, 62 [53-71] years; 3470 [51.2%] male). In the total cohort, care-element adherence improved from 52% to 76% (P < .001), no significant differences were found in serious complications (from 6.2% to 4.9%; P = .08) or 30-day mortality (from 0.71% to 0.93%; P = .50), 1-year mortality decreased from 7.1% to 4.6% (P < .001), mean (SD) LOS decreased from 9.4 (7.0) to 7.8 (5.0) days (P < .001), and 30-day readmission rates were unchanged (from 13.4% to 11.7%; P = .12). After adjustment for patient characteristics, the LOS mean difference decreased 0.71 days (95% CI, -1.13 to -0.29 days; P < .001), with no significant differences in adjusted 30-day readmission (-3.5%; 95% CI, -22.7% to 20.4%; P = .75), serious complications (1.3%; 95% CI, -26.2% to 39.0%; P = .94), or mortality (30-day mortality: 42% [95% CI, -35.4% to 212.3%]; P = .38; 1-year mortality: 8% [95% CI, -20.5% to 46.8%]; P = .62). The adjusted 1-year readmission rate was -15.6% (95% CI, -27.7% to -1.5%; P = .03) in favor of ERAS, and readmission LOS was shorter by 1.7 days (95% CI, -3.3 to -0.1 days; P = .04). Conclusions and Relevance: The results of this quality improvement study suggest that implementation of ERAS across multiple pathways may improve health care practitioner adherence to ERAS guidelines, LOS, and readmission rates at a system level.

The impact of COVID-19 on hospital admissions and emergency department visits: A population-based study.

BACKGROUND: As a result of the novel coronavirus disease 2019 (COVID-19), there have been widespread changes in healthcare access. We conducted a retrospective population-based study in Alberta, Canada (population 4.4 million), where there have been approximately 1550 hospital admissions for COVID-19, to determine the impact of COVID-19 on hospital admissions and emergency department (ED visits), following initiation of a public health emergency act on March 15, 2020. METHODS: We used multivariable negative binomial regression models to compare daily numbers of medical/surgical hospital admissions via the ED between March 16-September 23, 2019 (pre COVID-19) and March 16-September 23, 2020 (post COVID-19 public health measures). We compared the most frequent diagnoses for hospital admissions pre/post COVID-19 public health measures. A similar analysis was completed for numbers of daily ED visits for any reason with a particular focus on ambulatory care sensitive conditions (ACSC). FINDINGS: There was a significant reduction in both daily medical (incident rate ratio (IRR) 0.86, p<0.001) and surgical (IRR 0.82, p<0.001) admissions through the ED in Alberta post COVID-19 public health measures. There was a significant decline in daily ED visits (IRR 0.65, p<0.001) including ACSC (IRR 0.75, p<0.001). The most common medical/surgical diagnoses for hospital admissions did not vary substantially pre and post COVID-19 public health measures, though there was a significant reduction in admissions for chronic obstructive pulmonary disease and a significant increase in admissions for mental and behavioral disorders due to use of alcohol. CONCLUSIONS: Despite a relatively low volume of COVID-19 hospital admissions in Alberta, there was an extensive impact on our healthcare system with fewer admissions to hospital and ED visits. This work generates hypotheses around causes for reduced hospital admissions and ED visits which warrant further investigation. As most publicly funded health systems struggle with health-system capacity routinely, understanding how these reductions can be safely sustained will be critical.
