Evidence-practice gaps in P2Y12 inhibitor use after hospitalisation for acute myocardial infarction: findings from a new population-level data linkage in Australia.

BACKGROUND: P2Y12 inhibitor therapy is recommended for 12 months in patients hospitalised for acute myocardial infarction (AMI) unless the bleeding risk is high. AIMS: To describe real-world use of P2Y12 inhibitor therapy following AMI hospitalisation. METHODS: We used population-level linked hospital data to identify all patients discharged from a public hospital with a primary diagnosis of AMI between July 2011 and June 2013 in New South Wales and Victoria, Australia. We used dispensing claims to examine dispensing of a P2Y12 inhibitor (clopidogrel, prasugrel or ticagrelor) within 30 days of discharge and multilevel models to identify predictors of post-discharge dispensing and persistence of therapy to 1 year. RESULTS: We identified 31 848 patients hospitalised for AMI, of whom 56.8% were dispensed a P2Y12 inhibitor within 30 days of discharge. The proportion of patients with post-discharge dispensing varied between hospitals (interquartile range: 25.0-56.5%), and significant between-hospital variation remained after adjusting for patient characteristics. Patient factors associated with the lowest likelihood of post-discharge dispensing were: having undergone coronary artery bypass grafting (odds ratio (OR): 0.17; 95% confidence intervals (CI): 0.15-0.20); having oral anticoagulants dispensed 180 days before or 30 days after discharge (OR: 0.39, 95% CI: 0.35-0.44); major bleeding (OR: 0.68, 95% CI: 0.61-0.76); or being aged ≥85 years (OR: 0.68, 95% CI: 0.62-0.75). A total of 26.8% of patients who were dispensed a P2Y12 inhibitor post-discharge discontinued therapy within 1 year. CONCLUSION: Post-hospitalisation use of P2Y12 inhibitor therapy in AMI patients is low and varies substantially by hospital of discharge. Our findings suggest strategies addressing both health system (hospital and physician) and patient factors are needed to close this evidence-practice gap.

Improving the quality of person-centred healthcare from the patient perspective: development of person-centred quality indicators.

IMPORTANCE: International efforts are being made towards a person-centred care (PCC) model, but there are currently no standardised mechanisms to measure and monitor PCC at a healthcare system level. The use of metrics to measure PCC can help to drive the changes needed to improve the quality of healthcare that is person centred. OBJECTIVE: To develop and validate person-centred care quality indicators (PC-QIs) measuring PCC at a healthcare system level through a synthesis of the evidence and a person-centred consensus approach to ensure the PC-QIs reflect what matters most to people in their care. METHODS: Existing indicators were first identified through a scoping review of the literature and an international environmental scan. Focus group discussions with diverse patients and caregivers and interviews with clinicians and experts in quality improvement allowed us to identify gaps in current measurement of PCC and inform the development of new PC-QIs. A set of identified and newly developed PC-QIs were subsequently refined by Delphi consensus process using a modified RAND/UCLA Appropriateness Method. The international consensus panel consisted of patients, family members, community representatives, clinicians, researchers and healthcare quality experts. RESULTS: From an initial 39 unique evidence-based PC-QIs identified and developed, the consensus process yielded 26 final PC-QIs. These included 7 related to structure, 16 related to process, 2 related to outcome and 1 overall global PC-QI. CONCLUSIONS: The final 26 evidence-based and person-informed PC-QIs can be used to measure and evaluate quality incorporating patient perspectives, empowering jurisdictions to monitor healthcare system performance and evaluate policy and practice related to PCC.

Evidence-Practice Gaps in Postdischarge Initiation With Oral Anticoagulants in Patients With Atrial Fibrillation.

Background Oral anticoagulant (OAC) therapy reduces the risk of stroke in people with atrial fibrillation (AF), and is considered best practice; however, there is little Australian evidence around the uptake of OACs in this population. Methods and Results We used linked hospital admissions, pharmaceutical dispensing claims, medical services, and mortality data for people in Australia's 2 most populous states (July 2010 to June 2015). Among OAC-naïve people hospitalized with AF, we estimated initiation of OAC therapy within 30 days of discharge, and persistence with therapy in the first year. We analyzed both outcomes using multivariable Cox regression. In 71 184 people with AF (median age 78 years, 49% female), 22.7% initiated OAC therapy. Initiation was lowest in July to December 2011 (17.0%) and highest in July to December 2014 (30.1%) after subsidy of the direct OACs. In adjusted analyses, initiation was most likely in people with a CHA2DS2-VA score ≥7 (versus 0) (hazard ratio=6.25, 95% CI 5.08-7.69), and a history of venous thromboembolism (hazard ratio=2.65, 95% CI 2.49-2.83). Of the people who initiated OAC therapy, 39.9% discontinued within 1 year; a lower risk of discontinuation was associated with a CHA2DS2-VA score ≥7 (versus 0) (hazard ratio=0.22, 95% CI 0.14-0.35), or initiation on a direct OAC (versus warfarin) (hazard ratio=0.55, 95% CI 0.50-0.60). Conclusions We found that OAC therapy was severely underutilized in people hospitalized with AF, even among high-risk individuals. Reasons for this underuse, whether patient, prescriber, or hospital related, should be identified and addressed to reduce stroke-related morbidity and mortality in people with AF.

Does health system performance reporting stimulate change?

For numerous countries, including Canada, regular health system performance reporting has become increasingly routine if not mandated by legislation. In Canada, the health system performance reporting agenda includes multiple players at all levels from national organizations to provincial health (quality) councils and others. Canada, like many other countries, also participates in international health system performance reporting initiatives. Making sense of what all of these reporting initiatives are telling us about health system performance both within Canada and compared to other countries is becoming increasingly more challenging. For almost 20 years, the Canadian Institute for Health Information has worked with provinces, territories, and other key partners to develop comparable, standardized pan-Canadian performance indicators. Throughout this process, many lessons have been identified including the actionability one can reasonably expect from public reporting initiatives. This article outlines some of the key aspects of these lessons.

New Tools for Measuring and Improving Patient Safety in Canadian Hospitals.

The Canadian Institute for Health Information (CIHI) and the Canadian Patient Safety Institute (CPSI) have collaborated on a new measure of patient safety, along with a resource of evidence-informed practices. This measure captures four broad categories of harm in acute care hospitals, consisting of 31 clinical groups selected by clinicians. Analysis showed that harm was experienced in 1 of 18 hospital stays in Canada in 2014ߝ2015 and that no single category accounted for the majority of harmful events. Although CIHI and CPSI continue to work with hospitals and experts to further refine the methodology, the measure and associated Improvement Resource are useful new tools for monitoring and identifying harm, and have the potential to improve patient safety.

Systematic approach to evaluating and confirming the utility of a suite of national health system performance (HSP) indicators in Canada: a modified Delphi study.

OBJECTIVES: Evaluating an existing suite of health system performance (HSP) indicators for continued reporting using a systematic criteria-based assessment and national consensus conference. DESIGN: Modified Delphi approach with technical and leadership groups, an online survey of stakeholders and convening a national consensus conference. SETTING: A national health information steward, the Canadian Institute for Health Information (CIHI). PARTICIPANTS: A total of 73 participants, comprised 61 conference attendants/stakeholders from across Canada and 12 national health information steward staff. PRIMARY AND SECONDARY OUTCOME MEASURES: Indicator dispositions of retention, additional stakeholder consultation, further redevelopment or retirement. RESULTS: 4 dimensions (usability, importance, scientific soundness and feasibility) typically used to select measures for reporting were expanded to 18 criteria grouped under the 4 dimensions through a process of research and testing. Definitions for each criterion were developed and piloted. Once the definitions were established, 56 of CIHI's publicly reported HSP indicators were evaluated against the criteria using modified Delphi approaches. Of the 56 HSP indicators evaluated, 9 measures were ratified for retirement, 7 were identified for additional consultation and 3 for further research and development. A pre-Consensus Conference survey soliciting feedback from stakeholders on indicator recommendations received 48 responses (response rate of 79%). CONCLUSIONS: A systematic evaluation of HSP indicators informed the development of objective recommendations for continued reporting. The evaluation was a fruitful exercise to identify technical considerations for calculating indicators, furthering our understanding of how measures are used by stakeholders, as well as harmonising actions that could be taken to ensure relevancy, reduce indicator chaos and build consensus with stakeholders.

A Comparison of Administrative Data Versus Surveillance Data for Hospital-Associated Methicillin-Resistant Staphylococcus aureus Infections in Canadian Hospitals.

BACKGROUND In Canadian hospitals, clinical information is coded according to national coding standards and is routinely collected as administrative data. Administrative data may complement active surveillance programs by providing in-hospital MRSA infection data in a standardized and efficient manner, but only if infections are accurately captured. OBJECTIVE To assess the accuracy of administrative data regarding in-hospital bloodstream infections (BSIs) and all-body-site infections due to MRSA. METHODS A retrospective study of all (adult and pediatric) in-hospital MRSA infections was conducted by comparing administrative data against surveillance data from 217 acute Canadian hospitals (124 in Ontario, 93 in Alberta) over a 12-month period. Hospital-associated MRSA BSI cases in Ontario, and for all-body-site MRSA infections in Alberta were identified. Pearson correlation coefficients were used to compare the number of hospital-level MRSA cases within administrative versus surveillance datasets. The correlation of all-body-site MRSA infections versus MRSA BSIs was also assessed using the Ontario administrative data. RESULTS Strong correlations between hospital-level MRSA cases in administrative and surveillance datasets were identified for Ontario (r=0.79; 95% CI, 0.72-0.85) and Alberta (r=0.92; 95% CI, 0.88-0.94). A strong correlation between all-body-site and bloodstream-only MRSA infection rates was identified across Ontario hospitals (r=0.95; P<.0001; 95% CI, 0.93-0.96). CONCLUSIONS This study provides good evidence of the comparability of administrative and surveillance datasets in identifying in-hospital MRSA infections. With standard definitions, administrative data can provide estimates of in-hospital infections for monitoring and/or comparisons across hospitals. Infect Control Hosp Epidemiol 2017;38:436-443.

Palliative care coding practices in Canada since the introduction of guidelines and the HSMR indicator.

OBJECTIVES: This study examines palliative care (PC) coding practices since the introduction of a national coding standard and assesses a potential association with hospital standardised mortality ratio (HSMR) results. SETTING: Acute-care hospitals in Canada. PARTICIPANTS: ∼16 million hospital discharges recorded in Canadian Institute for Health Information (CIHI)'s Discharge Abstract Database from April 2006 to March 2013. PRIMARY AND SECONDARY OUTCOME MEASURES: In-hospital mortality, patient characteristics and service utilisation among all hospitalisations, HSMR cases and palliative patients. METHODS: We assessed all separations in the Discharge Abstract Database between fiscal years 2006-2007 and 2012-2013 for PC cases at national, provincial and facility levels. In-hospital mortality was measured among all hospitalisations (including HSMR cases) and palliative patients. We calculated a variant HSMR-PC that included PC cases. RESULTS: There was an increase in the frequency of PC coding over the study period (from 0.78% to 1.12% of all separations), and year-over-year improvement in adherence to PC coding guidelines. Characteristics and resource utilisation of PC patients remained stable within provinces. Crude mortality among HSMR cases declined from 8.7% to 7.3%. National HSMR declined by 22% during the study period, compared with a 17% decline in HSMR-PC. Provincial results for HSMR-PC are not significantly different from regular HSMR calculation. CONCLUSIONS: The introduction of a national coding standard resulted in increased identification of palliative patients and services. Aside from PC coding practices, we note numerous independent drivers of improving HSMR results, notably, a significant reduction of in-hospital mortality, and increase in admissions accompanied by a greater number of coded comorbidities. While PC impacts the HSMR indicator, its influence remains modest.

New mental health indicators provide a snapshot on performance of the mental health system in Canada.

Although the general hospital remains an important place for stabilizing crises, most services for mental illnesses are provided in outpatient/community settings. In the absence of comprehensive data at the community level, data that are routinely collected from general hospitals can provide insights on the performance of mental health services for people living with mental illness or poor mental health. This article describes three new indicators that provide a snapshot on the performance of the mental health system in Canada: self-injury hospitalization rate, 30-day readmission rate for mental illness and percentage of patients with repeat hospitalizations for mental illness. Findings suggest a need for the early detection and treatment of mental illnesses and for optimal transitions between general hospitals and community services.

Babies admitted to NICU/ICU: province of birth and mode of delivery matter.

Neonatal intensive care units (NICUs) and intensive care units (ICUs) provide care for newborns in need of specialized medical attention. Across Canada, rates of NICU/ICU admission vary. Due to the high cost of monitoring and interventions these admissions cost more than general newborn stays - whether the newborn is in a specialized NICU or in an ICU in those facilities without specialized units for newborns. This study explores the variation in NICU/ICU admissions and the characteristics of mothers and newborns associated with an increased likelihood of NICU/ICU admission. We focus further on the association between NICU/ICU admission and Caesarean section (C-section). After excluding multiple births, preterm births, small for gestational age births and those delivered by women with select complications, we find an increased risk for NICU/ICU admission for babies born by C-section as their only indication. NICU/ICU admission following C-section alone may not represent the most desirable pathway of care for these newborns.

Bariatric surgery in Canada: a focus on day surgery procedures.

Given the rise in obesity rates, increasing capacity for bariatric surgery has become a focus for some provincial planners. Four types of bariatric procedures are now performed in Canada; however, funding for the procedures varies by jurisdiction. This article provides an update to our previous article documenting the volume of in-patient bariatric procedures but focuses on the extent to which Canadians are increasingly receiving bariatric procedures in day surgery settings.

Falls among top reasons for transfers from continuing care to acute care hospitals in Canada.

There are limited data on the quality and safety of care for residents in continuing care settings. An analysis of the main reasons why residents, 75 and older, of continuing care facilities are transferred to acute care demonstrates that two of the top three reasons for transfers result from potentially avoidable events.

Thoracic cancer surgeries.

In 2005, Cancer Care Ontario (CCO) released Thoracic Surgical Oncology Standards. These standards were aimed at providing the best level of care for those undergoing thoracic surgery and encompass surgeon training, hospital ancillary services and minimum volume thresholds for surgeries of the lung and esophagus. The objective of the current study was to explore variations in thoracic cancer surgical volumes at the hospital level across Canada. Using data from the Discharge Abstract Database for 2007-2008, the cohort included patients admitted to hospital with a most responsible diagnosis of cancer and who had a lung or esophageal surgery. To determine the volume of surgeries performed per facility, we grouped patients according to the hospital facility performing the surgery. In Canada (excluding Quebec and Prince Edward Island), there were a total 4,509 lung and 587 esophageal cancer procedures performed in 94 hospitals in 2007-2008. For both types of surgeries, Ontario hospitals performed approximately half of the procedures. Overall, 12 hospitals performed at or over the volume of surgeries for lung cancer as indentified by the CCO standards, while 10 did so for esophageal cancer. Nine hospitals performed both lung and esophageal cancer surgeries at or over the suggested volumes. Higher volumes of lung and esophageal cancer-related surgeries have been associated with improved patient outcomes. Here we present a snapshot of the distribution of cancer-related lung and esophageal surgeries across Canada (excluding Quebec and Prince Edward Island).

Unsentimental education: learning from the workers' compensation boards experience.

Hurley et al. document the rise of care provided by workers' compensation boards (WCBs) in Canada and suggest that they potentially represent the "proverbial canaries in the coal mine) for the publicly funded healthcare system. Given WCBs' potential draw on similar resources and their ability to purchase services through incentive-based funding, some may argue that these systems do indeed challenge our current understanding of equitable access under the public system. Here we suggest, however, that while in some circumstances WCB behaviours and policies can create problems for the universal system, they can also serve as role models in their emphasis on prevention, evidence-based practice and timely service.

Why healthcare renewal matters: lessons from diabetes.

In this commentary, we offer evidence about the burden of chronic conditions and use diabetes as a case study to reveal the gap between recommended and actual care in Canada. What we found through our research is cause for concern - namely, that the care that Canadians with diabetes receive is simply not good enough (an inconvenient truth) and that the country has tremendous untapped potential to prevent chronic illness and improve the quality of care (a convenient truth). Our work and the work of others help Canadians understand the benefits that will accrue to them from investments to close the gap between what we know and what we do. Given the extent of recent initiatives highlighted in this commentary - initiatives that align with evidence regarding optimal prevention and chronic illness care - we should expect governments to simultaneously invest in assessing the degree to which progress is being attained. Without better data, more transparency and comprehensive reporting, Canadians will not be kept fully informed about the results of critical healthcare investments and governments will find it increasingly difficult to demonstrate that they are meeting their commitments.

Sex differences in hospital admissions from emergency departments in asthmatic adults: a population-based study.

BACKGROUND: Women represent the majority of adult patients hospitalized for asthma. Analyzing the course of emergency department (ED) visits before hospital admission can help understanding of the mechanisms behind the excess of hospitalizations in women. OBJECTIVE: To investigate sex differences in hospital admission rates in adult patients with asthma visiting EDs in Ontario. METHODS: Asthmatic patients 18 to 55 years old who visited Ontario EDs between April 1, 2003, and March 31, 2004, were identified using the Canadian Institute for Health Information's National Ambulatory Care Reporting System. The generalized estimating equations for binary outcome were used to model rates of hospital admission with sex, age, and triage (severity) score as covariates. Analysis was further stratified by the ED volume. RESULTS: Women represented 62.2% of all ED visits. They were on average older than men, but both groups had similar distributions of triage scores. Female patients accounted for more hospital admissions than male patients (7.4% vs 4.5%). After adjusting for age and triage score, women were more likely to be admitted than men (odds ratio, 1.64; 95% confidence interval, 1.41-1.90). The interaction found between sex and triage level indicates that hospitalized women may have less severe asthma than hospitalized men. Analysis by ED volume did not significantly alter the results. CONCLUSION: The higher admission rates in women may be related to sex differences in the subjective perception of dyspnea, management of asthma by ED physician, or inadequate ambulatory care strategies in women and thus merit further investigation.

Bariatric surgery in Canada: obesity rates for Canadian adults are much higher today than in the past; however, rates of bariatric surgery, a treatment for high-risk severely obese individuals, have not risen in parallel.

Obesity rates for Canadian adults are much higher today than in the past, raising questions about how to achieve healthy weights and mitigate the associated health risks. While not a solution at the population level, bariatric surgery may be a treatment option for a relatively small proportion of obese individuals. In Canada, unlike in the United States, no consistent trend was evident in the use of this surgery between 1996-97 and 2003-04 across the five provinces for which comparable data were available. In 2003-04, bariatric surgeries were performed predominantly for women (87%); the average length of stay in hospital was 5 days; and 1.4% of patients were readmitted to hospital within 7 days of their discharge after surgery.

Missed opportunity: patients who leave emergency departments without being seen.

The rate of patients who visit emergency departments (EDs) but leave before being evaluated and treated is an important indicator of ED performance. This study examines patient- and hospital-level characteristics that may increase the risk of patients leaving EDs before being seen. The data are from the National Ambulatory Care Reporting System, an administrative database, and represent 4.3 million patient visits made to 163 Ontario EDs between April 2003 and March 2004. Among these data, the proportion that left without being seen (LWBS) was 3.1% (136,805). The rate of LWBS was highest among patients aged 15 to 35 years, those with less acute conditions and facilities that handle the highest volume of patients. Facility rates were positively correlated with facility median ED length of stay, annual facility volume and percentage of inpatient admissions. Understanding patient and facility characteristics that increase rates of LWBS may inform the process of developing measures to ensure timely access to ED care for all who seek it.
