Who still prefers aggressive surgery for breast cancer? Implications for the clinical applications of clinical trials.

Conservative breast surgery and modified radical mastectomy may, according to recent reports, yield equivalent survival. Analysis of a 1985 Canada-wide study (N = 228) compared surgeons and oncologists still recommending modified radical mastectomy (30%) with those recommending less aggressive surgery (69%) for a hypothetical stage I patient. The groups did not differ significantly in most physician characteristics, estimated survival and cure probabilities, importance of most treatment goals, uncertainty about treatment choice, or most attitudinal responses. Although equally involved with and cognizant of the value of clinical trials, the modified radical group expressed more skepticism about the ability of trial results to be transferred to practice and to take sufficient account of patient uniqueness, indicating greater focus on variation than mean results. Trial results might be more readily adopted if they are reported in accessible data-bases, incorporating patient characteristics potentially relevant to treatment choice. This would allow clinicians to individualize treatment by analyzing patient subsets of their own choosing.

What role do patients wish to play in treatment decision making?

BACKGROUND: Although current ideology suggests patients should be active participants in decision making about their care, the literature suggests that patients wish to be informed but not involved. OBJECTIVE: To test the hypothesis that most patients want their physicians to take the responsibility for problem solving (PS, identifying the one right answer), but that many want to be involved in decision-making (DM, selecting the most desired bundle of outcomes) tasks. METHODS: Survey responses from 300 patients undergoing angiogram at a Toronto, Ontario, hospital were analyzed (response rate, 72%). Survey items included scales to measure desire for information and participation, including Autonomy Preference Index, the Krantz Health Opinion Survey, and the Deber-Kraetschmer Problem-Solving Decision-Making Scale measured on a scale from, 1 (doctor only) to 5 (patient only). RESULTS: Patients had a relatively high desire for information. On the Problem-Solving Decision-Making Scale, they overwhelmingly wished the PS tasks to be performed by or shared with the physician (98.4% of the 12 PS scores are between 1 and 3), but wanted to be involved in DM (78% of the 6 DM scores are between 3 and 5). Preference for handing over control to the physician was significantly greater for the vignette involving potential mortality (chest pain) than for the vignettes involving mainly morbidity (urinary problems) or quality of life (fertility). CONCLUSIONS: Although patients do not wish to be involved in PS tasks, few wish to hand over DM control to their physician. These findings suggest 2 major roles for clinicians--assisting patients in PS to structure choices and supporting them in making often difficult decisions.

The Canadian health care system: an overview.

Although health care is a provincial responsibility in Canada, universal hospital insurance was fully adopted by 1961; universal medical insurance followed 10 years later. Each province enacted universal insurance after the federal government offered to pay 50% of provincial hospital and medical care costs. Hospital insurance had wide public and provider support but universal medical care insurance was opposed by organized medicine. The federal government soon realized that it had no control over total expenditures and no mechanisms for controlling costs. In 1977 it enacted Bill C-37 which limited total federal contributions and made those contributions independent of provincial health care expenditures so that increased costs had to be met by the provinces. Since private health care insurance for universal benefits is prohibited by the federal terms of reference for health insurance, the provinces must raise the money by taxes and (in some provinces) premiums. Although prohibited by the terms of reference of the universal program, some provinces have adopted hospital user fees and are allowing their physicians to bill patients in excess of provincial fee schedules. The 1980s have seen increased confrontations between the federal and provincial governments and between the provinces and their providers. The issues are cost containment and control of the system. The provinces have two broad options. The first is more private funding through private insurance and user fees. The proposed new Canada Health Act will probably prohibit such charges. A second option involves greater control and management of the system by the provinces; this has already occurred in Quebec. Greater control is vigorously opposed by physicians and hospitals. The Canadian solution to health insurance problems in the past has been moderation. Extreme moves in either direction would represent a break with tradition, but they may prove to be unavoidable.

Overconfidence among physicians and nurses: the 'micro-certainty, macro-uncertainty' phenomenon.

Overconfidence in clinicians was examined in two independently designed studies, each using a different research approach. The first study examined treatment choices of physicians in treating breast cancer, and the second rapid decision making among nurses working in Intensive Care Units. In both studies, individual respondents were highly confident they had made the right choice ('micro-certainty'), although there was no consensus across respondents as to what the optimal treatment would be ('macro-uncertainty'). The difference between micro-certainty of individuals and macro-uncertainty within the clinical community may cast some light on the persistence of practice variation. The implications of overconfidence in clinical treatment for patients, practitioners, and professional regulation are discussed.

Health care in Canada: current trends and issues.

Canada's universal health care system is perceived as threatened by rising costs, an aging population, and technological growth. This popular and successful program has largely kept costs under control while maintaining quality and ensuring equity. However, its success demonstrates the limits of medical care; remaining health problems are less amenable to improvement by merely improving access to traditional services. A widening view of health implies a larger health role in other policy arenas, and a larger group of legitimate participants; coordinating an evolving and expanding system becomes increasingly difficult. Policy options include some combination of laissez faire, business as usual, managed care, manpower regulation, and system change. Change implies controversy and conflict. Hard decisions are clearly ahead.

The determinants of treatment choice in end-stage renal disease: can we generalize about decision making from specific studies?

Practitioner judgments about treatments for hypothetical end-stage renal disease patients were examined by two mailed surveys. It was hypothesized that treatment choice was a function of four hierarchically arranged sets of factors: disease- and treatment-specific, patient-specific, environment- and institution-specific, and practitioner-specific. The first survey identified six vignettes for which the case-specific factors alone did not yield a generally accepted treatment decision. These six cases were used in the second survey, whose results are reported here. Practitioner-specific characteristics were found to be only weakly related to treatment choice. Guttman scale analysis showed no significant practitioner propensity to use any given treatment. Instead, the number of colleagues in a respondent's renal unit picking a given therapy for a given patient was the strongest predictor of an individual's choice. Contextual factors--clinical details of the case and decision rules within the institution--appeared to overwhelm provider-specific tendencies; characteristics of the decision generally outweighed characteristics of the decision maker. This framework of factors may be useful for analyzing inter-provider variation. Consequences for certain approaches to the study of decision making (especially single-site studies and regression-based models) are noted.

Using explicit decision rules to manage issues of justice, risk, and ethics in decision analysis: when is it not rational to maximize expected utility?

Concepts of justice, risk, and ethics can be merged with decision analysis by requiring the analyst to specify explicity a decision rule or sequence of rules. Decision rules are categorized by whether they consider: 1) aspects of outcome distributions beyond central tendencies; 2) probabilities as well as utilities of outcomes; and 3) means as well as ends. This formulation suggests that distribution-based decision rules could address both risk (for an individual) and justice (for the population). Rational choice under risk if choices are one-time only (vs. repeated events) or if one branch contains unlikely but disastrous outcomes might ignore probability information. Incorporating risk attitude into decision rules rather than utilities could facilitate use of multiattribute approaches to measuring outcomes. Certain ethical concerns could be addressed by prior specification of rules for allowing particular branches. Examples, including selection of polio vaccine strategies, are discussed, and theoretical and practical implications of a decision rule approach noted.

Contraception with the cervical cap: effectiveness, safety, continuity of use, and user satisfaction.

With the growing interest in barrier contraceptive methods, the cervical cap has come back into use in North America. We examined the cap's effectiveness, safety, continuity of use, and user satisfaction among 617 women who were fitted at a family planning clinic in Toronto, Canada, between May 1981 and November 1983. Follow-up information was available for 516 of these women. Using a life table analysis with Bayesian adjustment, the probability of becoming pregnant after 12 months of use was 0.166 with a standard error of 0.022. There is evidence that after 1 year of use the caps deteriorate and that this deterioration may increase the risk of pregnancy. Many of the women in this study were very satisfied with the cervical cap; however, such problems as dislodgement, discomfort to user and partner, difficulty with insertion and removal, and unpleasant odour affected acceptability and continuity of use. It is likely that these problems could be alleviated by improving the quality of or changing the materials, modifying the design to improve the fit, and providing a greater range of sizes.

Assessment of Ontario's Geriatric Preventive Dentistry Program.

Ontario's Geriatric Preventive Dentistry Program (mandated under the Health Protection and Promotion Act) is assessed using the rational comprehensive approach. Policy options are examined, taking into account population characteristics, the nature of the health problem, current service delivery policy and resources, and barriers to access. Examining the 1974 Task Force recommendations, sets of draft guidelines issued in 1982, 1983, and 1984, and the revised 1985 guidelines as implemented, one can note changes in the benefits offered and in eligibility for coverage. The final program appears to be largely a symbolic policy response, which is unlikely to have major implications for either efficiency or community effectiveness. Implications of the current program, including the possibility it may be a precursor to more effective policies, are noted.

Public health in Canada: a comparative study of six provinces.

PURPOSE: To describe the public health systems and their projected futures in six provinces in the context of two developments: 1) the emerging discourse on population health and 2) the trend toward regionalization of the health care system. METHODS: Telephone interviews with key informants and key document review. RESULTS AND CONCLUSIONS: Communicable disease control and health protection are currently the "core businesses" of public health; the population health discourse has not resulted in mandated programming. The reality is a retrenchment of public health scope during a time that should be considered conducive to expansion. Only Ontario has not regionalized its health care system, although public health is already delivered regionally. Alberta, Saskatchewan and Manitoba have either evolved or are evolving toward an integrated health system. There were concerns about the potential impact on public health identity and funding of this "vertical integration". Regionalization of public health may result in units that are too small to support adequate local expertise and may jeopardize development and enforcement of province-wide programs.

From equal access to health care to equitable access to health: a review of Canadian provincial health commissions and reports.

Having achieved equality of access to health care, Canadian policymakers are setting new policy goals, within resource constraints, primarily to achieve equity of access to health. Across the country, provincial royal commissions have explored a number of policy options to achieve this goal. These options are reviewed and critically analyzed within the context of such challenges in health policy as insufficient access to high-technology care and the limits of medical care, and such external challenges as economic and demographic trends, federal-provincial disputes, and ideological beliefs. Particular attention is given to the implications of a broader definition of health and the concept of regional health authorities. Based on the provincial reviews, the authors conclude that Canada wants to achieve equitable access to health. With the shift of health policy away from the formerly protected arena of medical care, achieving equitable access to health will require both an alteration of priorities and values and considerable political will. Canada will be forced to meet these new challenges to maintain current achievements and to make its system even more successful.

Corporatization and deprivatization of health services in Canada.

Canada's system of health services has been shaped by the forces and values in the Canadian political, cultural, social, and economic environment; these forces continue to place constraints on future changes. We distinguish between "corporatization" and "privatization", and the implications of each for improved efficiency of the system. Although the organization of health services is, in certain provinces, undergoing significant structural changes, there is evidence that rather than privatizing, the system may actually be continuing to experience what we have termed deprivatization, as the scope of government involvement expands to include a more comprehensive definition of health care. Trends in Canada differ considerably from those in the United States; universal health insurance has curbed the ability and desire of institutions to exclude members of some socioeconomic groups from receiving care. U.S.-based models, if applied to Canada, could lead to both higher costs and lower quality of care. Considerable efficiencies can be realized within Canada's current system.

Canadian Medicare: can it work in the United States? Will it survive in Canada?

Any discussion of health care reform in the United States inevitably draws comparisons from the Canadian model. This Article frames the debate over the merits of the Canadian system by introducing its basic features, exploring its advantages, and discussing its limitations. In evaluating the prospects for a Canadian-type system in the United States, the author focuses on the need to rethink--as Canada has--the viability of market-based approaches to health care.

Innovative revenue generation.

Innovative revenue generation by Canadian hospitals is drawing increasing attention. After a critical examination of the literature, we classified these into six areas: clinical/diagnostic insured services, clinical/diagnostic non-insured services, hotel services, retail services, administrative services and financial activities. We concluded that many Canadian hospitals are engaging in innovative revenue generation activities, the success of such activities has been mixed, there are many factors to consider when selecting revenue generation activities, many aspects of innovative revenue generation involve sophisticated business and risk management skills not traditionally required in hospital management, and implementation of many such activities requires support from the hospital board, hospital staff and medical staff.

The merger that wasn't: lessons for senior administrators.

A turbulent health care environment has prompted some hospitals to consider integrating services and in some cases merge entirely. Fundamental lessons may be learned by studying how an attempted merger between Women's College Hospital and The Toronto Hospital in Toronto failed--despite board and senior executive support. Clarity of purpose, involvement of essential external and internal stakeholders, rational analysis, ideological fit and political expediency are a few key elements to consider. Once initiated, changes of this magnitude may take on a life of their own with often unpredictable results.

Managing health services organizations with an educational mission: the case of Canada.

Teaching hospitals represent a major segment of the Canadian health system, accounting for a disproportionate number of beds, patient days, and separations. Thus, although only six percent of hospitals are classified as teaching hospitals, they are responsible for about 36 percent of total hospital operating expenses. While affiliation with a medical school presents unique opportunities for the teaching hospital and increases its prestige, there are clear costs associated with affiliation. Administrators have less control over resource allocation decisions, including the types of teaching programs offered. Teaching hospitals cannot unilaterally design their own teaching programs around specialties and subspecialties of their own choosing; decisions related to teaching programs have a direct impact on the services provided by the hospital and may negatively affect the hospital's ability to fulfill its patient care mission. As education budgets are constrained, teaching hospitals are expected to assume outstanding teaching-related expenses. Teaching hospitals are also expected to shift some of their teaching to alternative settings, such as the community. Thus, teaching hospital administrators will require a strong background in finance as well as negotiation and political skills.

Physicians in health care management: 8. The patient-physician partnership: decision making, problem solving and the desire to participate.

How reasonable are expectations that patients will participate in care decisions? The previous article in this series reviewed models of the patient-physician relationship and views on the extent to which patients want to be informed; it also described one information tool--the interactive videodisc. This article reviews literature on the extent to which patients wish to be involved in making decisions about their care. Neither "sensitive paternalism" nor "informed consent" appears to be ideal. The author suggests a distinction between two elements of choice: problem solving and decision making. This distinction helps in identifying appropriate roles for patient and provider, thereby leading to genuine shared decision making.

Physicians in health care management: 7. The patient-physician partnership: changing roles and the desire for information.

Historical views of the patient-physician relationship assumed that the physician's role was to act in the best interests of the patient and to direct care and make decisions about treatment on the patient's behalf. However, under current legal and ethical principles, beneficence is no longer sufficient; respect for autonomy is paramount, necessitating patient participation. None the less, physicians question whether patient participation is realistic in actual clinical situations. This first of two articles reviews models of the patient-physician relationship and the literature about barriers to participation, the effect of participation on patient outcome and the extent to which patients want to be informed. The image of a dependent patient who prefers to be sheltered from harsh truths is not supported. It appears that most patients wish to have information, although there is an identifiable proportion who do not. To be understood, health information must be presented in a way that is appropriate to the patient. Format, content and timing of the material are all important. Mechanisms for incorporating such information into busy clinical practices are crucial.
