High-cost users of Ontario's healthcare services.

Approximately 1.5% of ontario's population, represented by the top 5% highest cost-incurring users of ontario's hospital and home care services, account for 61% of hospital and home care costs. Similar studies from other jurisdictions also show that a relatively small number of people use a high proportion of health system resources. Understanding these high-cost users (hcus) can inform local healthcare planners in their efforts to improve the quality of care and reduce burden on patients and the healthcare system. To facilitate this understanding, we created a profile of hcus using demographic and clinical characteristics. The profile provides detailed information on hcus by care type, geography, age, sex and top clinical conditions.

Making health system performance measurement useful to policy makers: aligning strategies, measurement and local health system accountability in ontario.

This study examined the experience of the Ontario Ministry of Health and Long-Term Care in enhancing its stewardship and performance management role by developing a health system strategy map and a strategy-based scorecard through a process of policy reviews and expert consultations, and linking them to accountability agreements. An evaluation of the implementation and of the effects of the policy intervention has been carried out through direct policy observation over three years, document analysis, interviews with decision-makers and systematic discussion of findings with other authors and external reviewers. Cascading strategies at health and local health system levels were identified, and a core set of health system and local health system performance indicators was selected and incorporated into accountability agreements with the Local Health Integration Networks. despite the persistence of such challenges as measurement limitations and lack of systematic linkage to decision-making processes, these activities helped to strengthen substantially the ministry's performance management function.

Understanding the Unattached Population in Ontario: Evidence from the Primary Care Access Survey (PCAS).

To measure primary care access on an ongoing basis, the Ontario Ministry of Health and Long-Term Care implemented the Primary Care Access Survey (PCAS) in 2006. The PCAS, a cross-sectional telephone survey, samples approximately 8,400 Ontario adults each year. It collects information on access to a family doctor, use of services, health status and socio-demographics. Analysis of the 2007-2008 PCAS (n=16,560) shows that 7.1% of Ontario's adults were without a family doctor (i.e., unattached). The attached and unattached populations differed on socio-demographic and health characteristics. Emergency department use was similar between the two groups, but walk-in clinic use was higher among the unattached. The unattached were less likely to have used care for immediate issues but accessed care in a more timely fashion than the attached. This initial exploration of the PCAS provides a better understanding of some of the differences between the attached and unattached populations in Ontario.

Hospital standardized mortality ratio: the way forward in Ontario.

Variations in quality of care persist despite an increased understanding of optimal practice and an improved ability to monitor outcomes. The reporting of hospital standardized mortality ratios (HSMRs) is an important step in highlighting the need to improve quality; but, as with most measures, the HSMR is not without flaws. Intense debate in the United Kingdom and the United States, and now here in Canada, has focused too much on the shortcomings of this measure and not enough on the issue at hand. The Ontario Ministry of Health and Long-Term Care--assuming our commitment to steward the healthcare system--embraces the themes of transparency and accountability as key tools in focusing attention on system performance and quality. The analysis of HSMRs in Ontario has indicated limitations to its interpretation, similar to those observed in the Winnipeg Regional Health Authority. The HSMR may not be a specific measure of adverse events, but this does not negate its usefulness in tracking the impact of quality improvement initiatives over time; it may be considered a valuable tool among a suite of indicators. In light of this, there is an opportunity to develop better statistics, including better data and measurement frameworks, and to educate the public to facilitate accurate interpretation, which will drive improvements in practice, quality and patients' experiences.

Regionalization reigns--but is care being delivered accordingly? An evaluation of perinatal care delivery in a regionalized child health network.

The Child Health Network for the Greater Toronto Area (CHN), a network of 20 hospitals and 9 community care access centres, assessed one component of its early progress in building a regionalized system of perinatal care. Focusing on the relationship between hospital level of care and gestational age, the study showed that most births occurred at appropriately designated facilities. However, a quarter of newborns of gestational age <32 weeks were delivered at a lower level of care than is considered optimal. CHN's ongoing research will offer opportunities to assess the impact of regional models on their foremost goal--quality clinical care.

Effectiveness and efficiency of different guidelines on statin treatment for preventing deaths from coronary heart disease: modelling study.

OBJECTIVE: To examine the potential effectiveness and efficiency of different guidelines for statin treatment to reduce deaths from coronary heart disease in the Canadian population. DESIGN: Modelled outcomes of screening and treatment recommendations of six national or international guidelines--from Canada, Australia, New Zealand, the United States, joint British societies, and European societies. SETTING: Canada. DATA SOURCES: Details for 6760 men and women aged 20-74 years from the Canadian Heart Health Survey (weighted sample of 12,300,000 people) that included physical measurements including a lipid profile. MAIN OUTCOME MEASURES: The number of people recommended for treatment with statins, the potential number of deaths from coronary heart disease avoided, and the number needed to treat to avoid one coronary heart disease death with five years of statin treatment if the recommendations from each guideline were fully implemented. RESULTS: When applied to the Canadian population, the Australian and British guidelines were the most effective, potentially avoiding the most deaths over five years (> 15,000 deaths). The New Zealand guideline was the most efficient, potentially avoiding almost as many deaths (14,700) while recommending treatment to the fewest number of people (12.9% of people v 17.3% with the Australian and British guidelines). If their "optional" recommendations are included, the US guidelines recommended treating about twice as many people as the New Zealand guidelines (24.5% of the population, an additional 1.4 million people) with almost no increase in the number of deaths avoided. CONCLUSIONS: By focusing recommendations on people with the highest risk of coronary heart disease, the Canadian, US, and European societies guidelines could improve either their effectiveness (in terms of hundreds of avoided deaths) or efficiency (in terms of thousands of fewer people recommended treatment) in the Canadian population.

Defining needs-based urban health planning areas is feasible and desirable: a population-based approach in Toronto, Ontario.

Reporting health data for large urban areas presents numerous challenges. In the case of Toronto, Ontario, amalgamation in 1998 merged six census subdivisions into one mega-city, resulting in the disappearance of standard reporting units. A population-based approach was used to define new health planning areas. Census tracts were used as building blocks and combined according to residential income homogeneity, respecting natural and man-made boundaries, forward sortation areas and the City of Toronto's community neighbourhoods whenever possible. Correlations and maps were used to establish area boundaries. The city was divided into 5 major planning areas which were further subdivided creating 15 minor areas. Both major and minor areas showed significant differences in population characteristics, health status and health service utilization. This commentary demonstrates the feasibility and describes the outcomes of one method for establishing planning and reporting areas in large urban centres. Next steps include the further generation of health data for these areas, comparisons with other Canadian urban areas, and application of these methods to recently announced Ontario Local Health Integration Networks. These areas can be used for planning and evaluating health service delivery, comparison with other Canadian urban areas and ongoing monitoring of and advocacy for equity in health.

Variation in emergency department visits for conditions that may be treated in alternative primary care settings.

The purpose of this report is to examine Ontario's geographic variation in emergency department (ED) visits for conditions that may be treated in alternative primary care settings. We studied all visits to Ontario EDs in 2002/03 and calculated county-specific age-standardized rates. Overall in Ontario, there were 3174 ED visits per 100,000 population aged 1-74 for conditions that could be treated in alternate primary care settings, but rates varied widely across counties. They were higher in rural counties with rates up to 7-fold higher than the provincial average. Urban counties had lower rates, some were less than one-third of the provincial average. Further research is needed to determine the relationship between ED utilization and primary care capacity.

Modelling strategies for controlling SARS outbreaks.

Severe acute respiratory syndrome (SARS), a new, highly contagious, viral disease, emerged in China late in 2002 and quickly spread to 32 countries and regions causing in excess of 774 deaths and 8098 infections worldwide. In the absence of a rapid diagnostic test, therapy or vaccine, isolation of individuals diagnosed with SARS and quarantine of individuals feared exposed to SARS virus were used to control the spread of infection. We examine mathematically the impact of isolation and quarantine on the control of SARS during the outbreaks in Toronto, Hong Kong, Singapore and Beijing using a deterministic model that closely mimics the data for cumulative infected cases and SARS-related deaths in the first three regions but not in Beijing until mid-April, when China started to report data more accurately. The results reveal that achieving a reduction in the contact rate between susceptible and diseased individuals by isolating the latter is a critically important strategy that can control SARS outbreaks with or without quarantine. An optimal isolation programme entails timely implementation under stringent hygienic precautions defined by a critical threshold value. Values below this threshold lead to control, but those above are associated with the incidence of new community outbreaks or nosocomial infections, a known cause for the spread of SARS in each region. Allocation of resources to implement optimal isolation is more effective than to implement sub-optimal isolation and quarantine together. A community-wide eradication of SARS is feasible if optimal isolation is combined with a highly effective screening programme at the points of entry.

Critical role of nosocomial transmission in the toronto sars outbreak.

We develop a compartmental mathematical model to address the role of hospitals in severe acute respiratory syndrome ( SARS ) transmission dynamics, which partially explains the heterogeneity of the epidemic. Comparison of the effects of two major policies, strict hospital infection control procedures and community-wide quarantine measures, implemented in Toronto two weeks into the initial outbreak, shows that their combination is the key to short-term containment and that quarantine is the key to long-term containment.

Under-reporting of live births in Ontario: 1991-1997.

OBJECTIVE: To examine unregistered births in Ontario and consider related factors, including adoption of administrative fees for birth registration. METHODS: Documents from both the parents and the attending physician are required for births to be entered into Ontario's live birth database. Our study used data from the Ontario Registrar General to look at the prevalence and characteristics of unregistered births, and a survey of municipal clerks to identify municipalities charging fees for parental documentation. RESULTS: The percentage of births going unrecorded increased threefold from 1991 to 1997. The odds of an unregistered birth were higher for teenage mothers, low birthweight babies, and mothers residing in a municipality that charged birth registration fees. CONCLUSION: The introduction of registration fees by some municipalities appears to account for an increase in unregistered births. It is recommended that the Ontario Registrar General work to remove financial and administrative barriers that compromise birth statistics.
