Mammography messages in popular media: implications for patient expectations and shared clinical decision-making

OBJECTIVE

To examine the relationship between the quantity and content of information about mammography in popular magazines and the educational level of their target audience.

DESIGN

Articles published in popular magazines from January 1988 through April 1994 in which >or= 25% of all readers were females >or= 35 years of age were identified (n=65). We used the proportion of readers who were college graduates to stratify the magazines into three education levels. We used a content analysis to assess the relationship between media messages about mammography and readers' education levels.

RESULTS

Seventy-eight percent of lowest education level articles were categorized as persuasive or prescriptive compared with 28% of articles in the highest education level (P < 0.01). Only 26% of the lowest education level articles that discussed screening guidelines for women under 50 years of age considered the issue controversial, while 59% of the high education level articles considered it controversial (P < 0.01).

CONCLUSION

Women with lower education levels received a clearly persuasive or prescriptive message urging mammography screening, while higher educated women received more balanced and informative messages. Such differences suggest that women may be entering their physicians' offices with very different sets of information from which to draw when faced with clinical decisions. Physicians and other health-care providers should be aware of these potential differences, and further research should be done to explore the relationship between women's preferences for participation in shared decision-making and the types of messages they are receiving from popular media.

The explosion in paid home health care in the 1990s: who received the additional services?

OBJECTIVE

Public expenditures for home health care grew rapidly in the 1990s, but it remains unclear to whom the additional services were targeted. This study tests whether the rapidly increasing expenditures were targeted to the elderly with high levels of disability and low levels of social support, 2 groups that have historically been higher users of paid home health and nursing home services.

METHODS

The Asset and Health Dynamics Study, a nationally representative, longitudinal survey of people > or = 70 years of age (n = 7,443), was used to determine the association of level of disability and level of social support with the use of paid home care services in both 1993 and 1995. Multivariable regression models were used to adjust for sociodemographics, recent hospital or nursing home admissions, chronic medical conditions, and receipt of informal care from family members.

RESULTS

Those with higher levels of disability received more adjusted weekly hours of paid home care in both 1993 and 1995. In 1993, users of paid home care with the least social support (unmarried living alone) received more adjusted weekly hours of care than the unmarried elderly living with others (24 versus 13 hours, P < 0.01) and the married (24 versus 18 hours, P = 0.06). However, by 1995, those who were unmarried and living with others were receiving the most paid home care: 40 versus 26 hours for the unmarried living alone (P < 0.05) and 24 hours for the married (P < 0.05).

CONCLUSIONS

The recent large increase in formal home care services went disproportionately to those with greater social support. Home care policy changes in the early 1990s resulted in a shift in the distribution of home care services toward the elderly living with their children.

A National Study of the Quantity and Cost of Informal Caregiving for the Elderly with Stroke

56

Background: As the US population ages, increased stroke incidence will result in higher stroke-associated costs. While estimates of direct costs exist, little information is available regarding informal caregiving costs for stroke patients. Objective: To determine a nationally representative estimate of the quantity and cost of informal caregiving for elderly stroke patients. Methods: We used data from the first wave (1993) of the Asset and Health Dynamics (AHEAD) Study, a longitudinal study of people over 70 living in the community, to determine average weekly hours of informal caregiving. Multivariate and logistic regression analyses were performed to examine association of stroke and other covariates and assess the probability of receiving informal care. Average annual cost for informal caregiving was calculated. Results: Of the 7443 respondents, 656 (6%) reported a history of stroke. Of those, 375 (57%) reported stroke-related health problems (SRHP). After adjusting for cormorbid conditions, social support and sociodemographics, the proportion of patients receiving informal care increased with stroke severity, and there was a significant association of weekly hours of caregiving with stroke category (p<0.01). Using the mean 1998 wage for a home health aide ($8.20/hr.) as the value for family caregiver time, the expected yearly caregiving cost per stroke ranged from $3500 to $7600, which would result in an annual cost of more than $5.7 billion for stroke-related informal caregiving in the US. Conclusions: The economic burden of informal caregiving following stroke has not been studied previously. Informal caregiving occurs frequently; associated costs are substantial and should be considered when estimating the cost of stroke treatment.

Gender disparities in the receipt of home care for elderly people with disability in the United States

CONTEXT

Projected demographic shifts in the US population over the next 50 years will cause families, health care practitioners, and policymakers to confront a marked increase in the number of people with disabilities living in the community. Concerns about the adequacy of community support are particularly salient to women, who make up a disproportionate number of disabled elderly people and who may be particularly vulnerable because they are more likely to live alone with limited financial resources.

OBJECTIVE

To address gender differences in receipt of informal and formal home care.

DESIGN, SETTING, AND PARTICIPANTS

Nationally representative survey conducted in 1993 among 7443 noninstitutionalized people (4538 women and 2905 men) aged 70 years or older.

MAIN OUTCOME MEASURE

Number of hours per week of informal (generally unpaid) and formal (generally paid) home care received by survey participants who reported any activity of daily living (ADL) or instrumental activity of daily living (IADL) impairment (n = 3109) compared by gender and living arrangement and controlling for other factors.

RESULTS

Compared with disabled men, disabled women were much more likely to be living alone (45.4% vs 16.8%, P<.001) and much less likely to be living with a spouse (27.8% vs 73.6%, P<.001). Overall, women received fewer hours of informal care per week than men (15.7 hours; 95% confidence interval [CI], 14.5-16.9 vs 21.2 hours; 95% CI, 19. 7-22.8). Married disabled women received many fewer hours per week of informal home care than married disabled men (14.8 hours; 95% CI, 13.7-15.8 vs 26.2 hours; 95% CI, 24.6-27.9). Children (>80% women) were the dominant caregivers for disabled women while wives were the dominant caregivers of disabled men. Gender differences in formal home care were small (2.8 hours for women; 95% CI, 2.5-3.1 vs 2.1 hours for men; 95% CI, 1.7-2.4).

CONCLUSION

Large gender disparities appear to exist in the receipt of informal home care for disabled elderly people in the United States, even within married households. Programs providing home care support for disabled elderly people need to consider these large gender disparities and the burden they impose on families when developing intervention strategies in the community.

Breast cancer screening in the United States and Canada, 1994: socioeconomic gradients persist

OBJECTIVES

This study compared rates of annual mammography screening across socioeconomic status between the United States and Canada in 1994.

METHODS

Population-based cross-sectional surveys were used to compare the rates.

RESULTS

Screening rates were higher in the United States than in Canada for women aged 50 to 69 years (47.3% vs 38.8%; P < .01). Women with higher education and with higher incomes were more likely to receive screening in both countries, with no significant differences between countries.

CONCLUSIONS

For women aged 50 to 69 years, screening rates in Canada have substantially increased relative to those in the United States. However, disparities in screening across levels of socioeconomic status persist in both countries.

"We got mail": electronic communication between physicians and patients

E-mail has the potential to improve both the quality and efficiency of healthcare service delivery. Despite the substantial growth of this form of communication over the past decade, its promise to patients, providers, and their health plans remains largely untapped. In this article we (1) review the literature on e-mail use between patients and providers; (2) identify challenges and opportunities facing managed care organizations that wish to maximize the potential of this form of communication; (3) describe the components of 2 systems aimed at enhancing e-mail use in clinical settings; and (4) discuss the implications of increased e-mail use for managed care.

Past-year use of outpatient services for psychiatric problems in the National Comorbidity Survey

OBJECTIVE

The authors present nationally representative descriptive data on 12-month use of outpatient services for psychiatric problems. They focused on the relationship between DSM-III-R disorders and service use in four broadly defined service sectors as well as the distribution of service use in multiple service sectors.

METHOD

Data from the National Comorbidity Survey were examined.

RESULTS

Summary measures of the seriousness and complexity of illness were significantly related to probability of use, number of sectors used, mean number of visits, and specialty treatment. One-fourth of the people in outpatient treatment were seen in multiple service sectors, but no evidence was found of multisector offset in number of visits.

CONCLUSIONS

Use of outpatient services for psychiatric problems appears to have increased over the decade between the early 1980s and early 1990s, especially in the self-help sector. Aggregate allocation of treatment resources was related to need, highlighting the importance of making provisions for specialty care in the triage systems currently evolving as part of managed care.

Patients' desires and expectations for medical care: a challenge to improving patient satisfaction

Patients' desires and expectations for medical care warrant scrutiny because of their potential influence on health care use and patient satisfaction and their effects on patients' perceptions of quality of care. To determine if desires and expectations for selected elements of medical care and specialty referral differ between VA outpatients and non-VA outpatients, we conducted a cross-sectional survey of patients at a VA medical center site and 2 primary care sites of its university affiliate. Of 390 eligible patients at the VA medical center site, 270 (69%) consented to participate and returned completed self-administered questionnaires. At its university affiliate sites, 119 (73%) of the 162 eligible patients completed questionnaires. Overall, patient desire and expectation for elements of medical care and specialty referral were similar and high at all study sites. Desire ranged from 33% for a blood test to check for anemia to 80% for heart auscultation. Desire for specialty referral for hypothetical scenarios averaged 71% and 61% among VA Medical Center patients and university affiliate patients, respectively. Patient demographics and socioeconomic status were poor predictors of desire for care. These results suggest (a) that VA medical center outpatients' desires and expectations for preventive medical care are not significantly different from those of non-VA outpatients, (b) that desire is often high for both highly recommended care and care that is not generally recommended or is controversial, and (c) that high levels of desire are not limited to patients of higher levels of socioeconomic status. In an effort to improve satisfaction, it is important to examine ways in which to address patients' desires and expectations for medical care, even while faced with competing health care spending priorities.

A comparison of cardiovascular procedure use between the United States and Canada

OBJECTIVE

To compare the relative volume and intensity of all types of cardiovascular procedures, noninvasive tests, and diagnostic imaging for all elderly individuals between the United States and the three largest Canadian provinces (Ontario, Quebec, and British Columbia) by patient age.

DATA SOURCES

Service volume data for the United States for a one percent random sample of claims obtained from Medicare's National Claims History System. Data for Canada were obtained from the Ministries of Health in the three provinces representing 100 percent of the claims received by each Ministry.

STUDY DESIGN

Design is a cross-sectional analysis of 1992 claims data.

DATA EXTRACTION METHODS

The volume of cardiovascular services was measured in terms of the relative value units (RVUs) used in the Medicare fee schedule to calculate payments. Services were disaggregated into nine clinical categories, and comparisons were made by type of cardiovascular service and patient age.

RESULTS

Overall, cardiovascular procedure RVUs per elderly beneficiary are 53 percent greater in the United States than in Canada. Differences are largest for surgical procedures such as carotid thromboendarterectomy and revascularization procedures and smallest for diagnostic imaging and noninvasive tests. The differences between the countries in the use of cardiovascular procedures increase markedly with age. For example, the United States-to-Canada ratio for PTCA use is 1.87 for persons age 65 to 69, but 7.68 for persons age 80 and older. For CABG, the ratios are 1.36 and 7.16, respectively.

CONCLUSIONS

Our findings suggest that global budgets in Canada result in lower levels of cardiovascular service use among the elderly, particularly among the very aged elderly. Patient age appears to play a much more important role in determining the recipients of cardiovascular procedures in Canada than in the United States. Whether these higher rates of procedure use among the very elderly in the United States compared to Canada reflect profligate service use or contribute to improved outcomes is uncertain.

Patients' desires and expectations for medical care in primary care clinics

To explore whether patients' desires for and expectations of medical care differ between the United States and Canada, we surveyed 652 patients and 105 physicians at primary care sites in Michigan and Ontario. Patient desires were similar at both sites, but expectations were higher in Michigan. Michigan physicians gave higher estimates of patient desire than physicians in Ontario. Physicians at both sites, however, similarly underestimated patients' desires. These between-site differences in expectation may reflect differences both in general cultural factors and in patient exposure to different clinical policies within the medical systems.

Medication management of depression in the United States and Ontario

OBJECTIVE

To compare rates of contact for mental problems and receipt of appropriate antidepressant medication management for persons in the general population with major depression in the United States and Ontario, Canada.

DESIGN

Survey using the U.S. National Comorbidity Survey and the Mental Health Supplement of the Ontario Health Survey.

PARTICIPANTS

All persons with major depression as described in DSM-III-R in the previous 12 months, from a multistage random sample of persons aged 21 to 54 years living in households in the United States (n = 574) and Ontario (n = 250) in 1990.

MEASUREMENTS AND MAIN RESULTS

Self-reported contact with general medical or mental health specialty providers for mental problems and appropriate medication management, defined as a combination of antidepressant medication use and four or more visits to any provider within the previous 12 months, were the main outcome measures. The proportion of depressed persons receiving appropriate management was lower in the United States than in Ontario (7.3% vs 14.9% in Ontario, adjusted odds ratio [AOR] 95% CI 0.4; 95% confidence interval [CI] 0.2, 0.8). This difference was largely the result of fewer Americans than Canadians having any mental health care from general medical physicians (9.6% in the United States vs 25.8% in Ontario; AOR 0.3; 95% CI 0.1, 0.5) rather than from specialty providers (20.8% in the United States vs 28.9% in Ontario; AOR 0.7; 95% CI 0.4, 1.1). These between-country differences were much greater for the poor than for those with higher incomes. The Ontario-United States AOR of making contact with either type of clinical provider was 7.5 (95% CI 2.7, 20.7) for lowest-income persons but 2.1 (95% CI 0.3, 5.6) for highest-income persons. The proportions of depressed recipients of any mental health care who received appropriate management were similar between countries (23.9% in the United States vs 27.7% in Ontario; AOR 0.8; 95% CI 0.3, 1.7).

CONCLUSIONS

Most persons with depression in the United States and Ontario do not receive appropriate medication management. The rate of appropriate medication management in the United States relative to Ontario is lower largely because there is less contact with general medical physicians for mental problems, especially for the poor. Economic barriers, rather than knowledge and attitudinal factors, appear to explain this difference.

Canadians' use of U.S. medical services

To explore the extent of cross-border care seeking among Canadians, we analyzed the growth and distribution of Ontario Health Insurance Plan expenditures for medical care services provided in the United States to Ontario residents from 1987 to 1995. Although total out-of-province spending is low relative to in-province spending, there is evidence of cross-border care seeking for cardiovascular and orthopedic procedures, mental health services, and cancer treatments. However, combined with a preliminary investigation of cross-border patient care seeking using nonpublic funding sources, these analyses do not support the perception of widespread cross-border medical care seeking by Ontario residents.

Physician relations in Canada: shooting inward as the circle closes

As economic disputes between physicians become more frequent, discussions between physicians are becoming increasingly important. Those seeking insight into how physician organizations might mediate these disputes may be able to learn from others who have had negotiating responsibilities for over a quarter of a century--the provincial medical associations in Canada. In this article we examine the structure, process, and outcomes of negotiations between physicians, with a focus on responses to new physician expenditure caps in Ontario, Alberta, and British Columbia. Early negotiations between physicians over changes in relative fees favored general practitioners because they were the dominant voting block within the associations. Despite fewer gains in the fee arena, specialists were willing to remain in the associations because all physicians generally enjoyed similar income growth. Under new physician expenditure caps, however, physicians have been unable to resolve conflicts over how to allocate income limits across specialties. Negotiations between physicians face expanding economic issues and diverging interests as expenditure caps force physicians to concentrate on total costs.

The growth of physician services for the elderly in the United States and Canada: 1987-1992

The authors compared the growth of expenditures, prices, and volume and intensity of physician services delivered to the elderly in the United States and Canada from 1987 to 1992 using claims-level data from U.S. Medicare and from Ontario, Quebec, and British Columbia. Services were classified into clinical categories and per capita annualized expenditure, price, and volume growth ratios were calculated for each category. The expenditure growth rate is higher in the United States than in Canada for evaluation and management services (8.8 percent versus 4.5 percent), but it is lower for procedures (2.9 percent in the United States versus 4.8 percent in Canada). For procedures, prices decreased 2.4 percent per year in the United States but increased 1 .0 percent per year in Canada, while volume increased faster in the United States (5.4 percent versus 3.8 percent in Canada). In both countries, high volume growth rates are observed in categories containing newly emerging procedures. Although policies to control prices appear easier to implement than policies to control the volume and intensity of medical care, their success in controlling expenditures is uncertain. Nonetheless, Canada has been more successful at controlling the growth in the volume of procedures than the United States.

Is language a barrier to the use of preventive services?

OBJECTIVE

To isolate the effect of spoken language from financial barriers to care, we examined the relation of language to use of preventive services in a system with universal access.

DESIGN

Cross-sectional survey.

SETTING

Household population of women living in Ontario, Canada, in 1990.

PARTICIPANTS

Subjects were 22,448 women completing the 1990 Ontario Health Survey, a population-based random sample of households.

MEASUREMENTS AND MAIN RESULTS

We defined language as the language spoken in the home and assessed self-reported receipt of breast examination, mammogram and Pap testing. We used logistic regression to calculate odds ratios for each service adjusting for potential sources of confounding: socio-economic characteristics, contact with the health care system, and measures reflecting culture. Ten percent of the women spoke a non-English language at home (4% French, 6% other). After adjustment, compared with English speakers, French-speaking women were significantly less likely to receive breast exams or mammography, and other language speakers were less likely to receive Pap testing.

CONCLUSIONS

Women whose main spoken language was not English were less likely to receive important preventive services. Improving communication with patients with limited English may enhance participation in screening programs.

The use of outpatient mental health services in the United States and Ontario: the impact of mental morbidity and perceived need for care

OBJECTIVES

This study compared the associations of individual mental health disorders, self-rated mental health, disability, and perceived need for care with the use of outpatient mental health services in the United States and the Canadian province of Ontario.

METHODS

A cross-sectional study design was employed. Data came from the 1990 US National Comorbidity Survey and the 1990 Mental Health Supplement to the Ontario Health Survey.

RESULTS

The odds of receiving any medical or psychiatric specialty services were as follows: for persons with any affective disorder, 3.1 in the United States vs 11.0 in Ontario; for persons with fair or poor self-rated mental health, 2.7 in the United States vs 5.0 in Ontario; for persons with mental health-related disability. 3.0 in the United States vs 1.5 in Ontario. When perceived need was controlled for, most of the between country differences in use disappeared.

CONCLUSIONS

The higher use of mental health services in the United States than in Ontario is mostly explained by the combination of a higher prevalence of mental morbidity and a higher prevalence of perceived need for care among persons with low mental morbidity in the United States.

Mental health care use, morbidity, and socioeconomic status in the United States and Ontario

This study focuses on mental health problems and compares the association of demographic and socioeconomic factors to the use of mental health specialty care and general medical care in the United States and the Canadian province, Ontario. It also examines how lack of insurance coverage in the United States and perceived need for care affects differences between the two countries. We employ a cross-sectional study design using the 1990 U.S. National Comorbidity Survey and the 1990 Mental Health Supplement to the Ontario Health Survey. Overall, 8.8% of Americans report one or more visits to the health sector for a mental health problem, compared to 6.9% of Canadians in Ontario. Americans with the highest incomes and no mental morbidity are much more likely to receive services than their Canadian counterparts. By contrast, Americans with the lowest incomes and high morbidity are much less likely to receive services for mental health problems than a similar group of Canadians. These results suggest that universal and comprehensive coverage, as exists in Ontario, does not necessarily lead to increased use of services with low value. However, the greater prevalence of perceived need for care among Americans with higher socioeconomic status and low mental morbidity suggests that the United States should be cautious in drawing lessons from other countries.

Differences in the use of psychiatric outpatient services between the United States and Ontario

BACKGROUND

The relation between health insurance and the use of mental health services is unclear. We compared the use of outpatient services for psychiatric problems in the United States and Ontario, Canada, among young and middle-aged adults according to self-reports of disorders listed in the Diagnostic and Statistical Manual of Mental Disorders (third edition, revised) and to other indicators of need.

METHODS

We analyzed two general-population surveys carried out separately in the United States and Ontario in 1990 that used identical assessments of need for services and questions about their use by persons 15 to 54 years of age.

RESULTS

Respondents in the United States were significantly more likely than those in Ontario to report having had psychiatric disorders, poor mental health, or workdays lost or cut short because of psychiatric problems in the previous year. A significantly higher proportion of respondents in the United States (13.3 percent) than in Ontario (8.0 percent) had obtained outpatient treatment in the previous 12 months for psychiatric problems. However, an analysis of subgroups found that the higher probability of the use of services in the United States was confined to people with less severe mental illness. The average number of visits did not differ significantly between the two countries among patients who had similar numbers of psychiatric disorders over the same time periods. There was a stronger match in Ontario than in the United States between the use of services and the measures of perceived need we considered.

CONCLUSIONS

Although the mental health care system in the United States provides treatment to a larger proportion of the population than that in Ontario, the match between some measures of need and treatment is not as strong in the United States. Any plans to expand coverage for psychiatric disorders in the United States must address this problem.

Healthy behaviors among women in the United States and Ontario: the effect on use of preventive care

OBJECTIVES

This study examined how several healthy behaviors among women in Ontario and the United States explained (1) the use of preventive health services, (2) differences in use between socioeconomic groups, and (3) differences in use between the two health systems.

METHODS

1990 data on women from the Ontario Health Survey (n = 22,985) and the US National Health Interview Survey (n = 19,092) were analyzed. A woman who avoided smoking and obesity, used seatbelts, and regularly engaged in aerobic exercise was defined as having a healthy lifestyle. Women were considered screened if they reported a mammogram or a breast exam within the previous year or a Pap smear within 2 years.

RESULTS

A healthy lifestyle was more common in the United States than Canada among more highly educated groups (odds ratio [OR] = 1.40; 95% confidence interval [CI] = 1.22, 1.60 for college educated) but less common in the United States for those with less than a high school education (OR = 0.52; 95% CI = 0.40, 0.67). Each additional unhealthy behavior decreased the odds of having undergone a mammogram in the previous year by 20%. However, adjusting for the number of unhealthy behaviors did not substantially change the relationship between socioeconomic status and use of preventive services.

CONCLUSIONS

The number of healthy behaviors is an important measure of demand for preventive health services. This measure varies across country and socioeconomic group.

Effect of mandatory radiology consultation on inpatient imaging use. A randomized controlled trial

OBJECTIVE

To determine if a mandatory radiology consultation service can decrease radiology resource use on inpatient internal medicine services.

DESIGN AND SETTING

Randomized controlled trial on 4 internal medicine services at a university hospital.

PATIENTS AND OTHER PARTICIPANTS

Six radiologists performed the intervention on 2 internal medicine services over a 12-month period. A total of 1022 patients were admitted to the 2 intervention services and 1178 patients were admitted to the 2 control services. Each was staffed by an attending internist and 3 house officers.

INTERVENTION

Each radiology examination required approval by the attending radiologist before it was performed.

MAIN OUTCOME MEASURE

Relative resource costs (relative value units [RVUs]), number of examinations per patient, proportion of patients with 1 or more tests, and mean length of stay (LOS).

RESULTS

Mean RVUs for the intervention group were 356.1, and for the control group, 336.0 (P=.5). Mean examinations per patient for both groups was 4.4. Mean LOS for the intervention group was 6.0 days, and for the control group, 6.1 days (P=.8).

CONCLUSIONS

An inpatient radiology consultation service, with a goal to reduce resource use, did not achieve its goal. A more appropriate use of time and expense for radiology utilization management may be in the outpatient setting.

Hospital utilization in Ontario and the United States: the impact of socioeconomic status and health status

We compared hospital use in Ontario and the United States for persons with different socioeconomic and health status.

METHODS

Cross-sectional study using the 1990 Ontario Health Survey and the 1990 National Health Interview Survey.

RESULTS

Admission rates averaged 31% higher in Ontario than in the United States, but international differences varied markedly across income and health status. At each level of health status, poor Canadians received one quarter to one third more admissions than their counterparts in the United States. However, higher income Canadians reporting excellent to good health had 50% more admissions than Americans, whereas those reporting fair or poor health had 10% fewer admissions.

CONCLUSIONS

The observation that higher income sick persons receive less hospital care in Ontario than in the U.S. provides support at the population level for what has been observed for specific technologies. This represents, in part, a redistribution of inpatient care to those most vulnerable to illness, such as the poor, who receive substantially more hospital care in Ontario.

A detailed comparison of physician services for the elderly in the United States and Canada

OBJECTIVE

To assess the relative volume and price of physician services in Canada and the United States.

DESIGN

A comparative analysis of 1992 claims data from Canadian provincial ministries of health and from the US Health Care Financing Administration.

PATIENTS

All elderly individuals in the 3 largest Canadian provinces, Ontario, Quebec, and British Columbia, and a 1% random sample of US elderly Medicare beneficiaries not enrolled in health maintenance organizations.

MAIN OUTCOME MEASURE

The volume of physician services measured in terms of the relative value units used in the Medicare fee schedule to calculate payments, with services disaggregated into clinically meaningful categories.

RESULTS

Canadian elderly receive a higher volume of physician services than US elderly. Because the provinces examined paid a much lower price per service, Canada had overall lower expenditures per elderly person than the United States. Canadian elderly received 44% more evaluation and management services, but 25% fewer procedures. Canada has a disproportionately lower volume of procedures for which there is low clinical consensus as to when they are indicated. Such procedures include cataract extractions and knee replacements.

CONCLUSION

The lower prices for physician services in Canada permit Canadian elderly to receive a higher volume of evaluation and management services, on the other hand, are constrained by both price and volume. These differences in the volume of physician services may be the result of differences in facility and physician supply.
