The overall aim of this thesis was to characterize patient-physician communication in oncology care with focus on the content and quality of the consultations from the perspectives of patients, oncologists and observer. Further, the aim was to explore oncologists’ perceived barriers against psychosocial communication in out-patient consultations. Finally, the aim was to evaluate different methods for evaluating communication in this setting. Routine oncology out-patient consultations from two different hospitals were audio-recorded. After the consultations, patients and oncologists perceptions of the content and quality of the communication were assessed using a self-report questionnaire. A nation-wide survey was performed to assess oncologists’ perceived barriers against psychosocial communication. Finally, the audio-recorded consultations were used for evaluating inter-rater reliability and feasibility of two different communication analysis instruments. Patient-physician consultations in oncology care are focused on the physical aspects of disease and treatment, both in terms of how often these issues were discussed and in terms of the amount of time spent on discussing them. Psychosocial issues, such as the disease’s effects on patients’ emotional or social functioning, are not always discussed during consultations, and the time spent on such discussions is limited. When psychosocial issues are discussed during the medical consultations, they are most often patient-initiated. Reasons for why psychosocial aspects are seldom discussed during the medical consultations can be the barriers concerning this kind of communication perceived by a large majority (93%) of the oncologists. Barriers against psychosocial communication were identified at organizational levels (including guidelines, routines, and resources) and individual levels (including physicians’ knowledge and attitudes). Furthermore, this thesis shows that there are methods with high feasibility and reliability for evaluating the content of patient-physician communication, in large study samples in oncology care. The method (observation/self-report) and perspective (patient, physician, and observer) used when evaluating communication affects the results. This needs to be considered when choosing evaluation methods in intervention studies. There are reasons to continue to evaluate, promote and implement promising ways of achieving better communication in clinical practice. Research should focus on how to overcome barriers against psychosocial communication.

Several factors inform health professionals decisions to migrate from developing to developed countries to practice their profession. This study explores the Push and Pull factors that informed African-trained physicians decisions to migrate to the province of Saskatchewan, how well they integrated into their new working environments upon arrival and how that might contribute to future migration and retention in Saskatchewan. Based on questionnaire surveys and face-to-face interviews, this study identified differences in the relative importance of precipitating factors for physicans from South, North and Other African nations. Although the majority of African-trained physicians for the study indicated that profession-related push factors were the precipitating factors for their migration, a smaller number did not cite these as important. Most respondents for the study integrated well into the health care system and have remained at their current location of practice because of the support they received from colleagues at their work places.

This thesis proposes a model for legalized Physician-Assisted Suicide [PAS] for adoption into Canadian legislation. The basis of this model is one which respects the individual freedom to make end-of-life decisions free from state interference. The research herein supports the provisions contained in Oregon legislation where PAS has been legalized on the basis that the Oregon model is consistent with the guarantees afforded under s.7 of the Charter of Rights and Freedoms. Oregon maintains strict regulatory barriers which protect against the threat of abuse which the Supreme Court reasoned in Rodriguez outweighed her s.7 rights to autonomy. This thesis will engage in the theories of Ronald Dworkin who supports the preservation of the sanctity of human life which Sopinka J. held prevailed over s. 7 violations in Rodriguez and seeks a model which respects individual freedom without compromising that sanctity or value of life.

Designing a software interface for healthcare requires thorough domain knowledge, and effective user research and benchmark analysis. This thesis examines the requirements for an improved patient information management system for emergency medicine and describes the iterative process of designing and evaluating the system. I conducted observational study of Emergency Department (ED) physicians’ workflow and information needs, from which I derived a set of functional requirements, created scenarios, performed hierarchical task analysis, and developed a preliminary user model for the patient information management system. Based on these, I developed an interface prototype and evaluated the design with a sample of ED physicians. I review the user testing and design iterations carried out and report on the design improvements made based on the user feedback.

There is no stronger or more enduring prohibition in medicine than the rule against the killing of patients by doctors. This prohibition is rooted in some medical codes and principles. Out standing among the principles surrounding these prohibitions are the principles of beneficence and non-maleficience. The contents of these principles in a way mark the professional integrity of the physician. But the modern approach to health care services pulls a demand for the respect of the individual right of self-determination. This demand is now glaring in almost all the practices pertaining to health care services. In end of life decisions, this modern demand is found much in practices like physician- assisted suicide and euthanasia. It demands that the physician ought to respect the wish and choice of the patient, and so, must assist the patient in bringing about his or her death when requested. In such manner, this views the principle of autonomy as absolute and should not be overridden in any circumstance. However, the physician on his part is part of the medical profession that has integrity to protect. This integrity in medical profession which demands that the physician works only towards the health care of the patient and to what reduces diseases and deaths often go contrary to this respect for individual autonomy. Thus faced with such requests by patients, the physician always sees his integrity in conflict with his demand to respect the autonomous choice of the patient and so has a dilemma in responding to such requests. This is the focus of this work,"Professional Integrity and the Dilemma in Physician- Assisted Suicide" However, the centre of my argument in this work is not merely though necessary to develop general arguments for or against the general justification of PAS, but to critically view the role played by the physicians in assisting the death of their patients as it comes in conflict with the medical obligation and integrity. Is it morally right, out rightly wrong or in certain situation permissible that physicians respond positively to the request of the patients for PAS? This is the overarching moral problem in the morality of physician- assisted suicide, and this work will consider this in line with the main problem in the work “the dilemma of professional physicians in the assistance of suicide.

This thesis applies the econometric projection approach to forecast the numbers of general practitioners (GPs) in Saskatchewan for the next 15 years at both provincial and the Regional Health Authorities (RHAs) levels. The projection results will provide the estimated level of GPs up to 2021 for policy makers to adjust their decision on health professionals planning.<p> Three hypothesized scenarios, which include the changes in population proportion, average income for GPs and a combination of both, are used for projections based on the regression results. The projections suggest a 4.34% expected annual increase of GPs if the proportions of children and seniors increase or decrease according to prediction for the next 15 years for Saskatchewan. At the RHAs level, 4.5% to 10.7% expected annual rate of increase for numbers of GPs is projected for the northern RHAs and Saskatoon RHA, while the expected increase for other urban RHAs will experience less than 1.5% increases.<p> The predicted changes in average income for GPs show insignificant effect for the expected changes in numbers of GPs. However, the second and third scenarios are not extended to the RHAs level due to lack of information, which requires additional data for both Saskatchewan physicians and population for further projection analysis.

Degenerative disease of the lumbar spine (DDLS) is a common condition for which surgery is beneficial in selected patients. Wide variation in surgical referral and rates of surgery has been observed contributing to unequal access to care. Our objectives were to examine (1) the variation in preferences for referral and surgery among surgeons, family physicians (FPs) and patients, (2) how FP referral practices compare with preferences and guideline recommendations, and (3) how the ‘enthusiasm’ of patients and physicians influence regional variation in surgical rates. We used conjoint analysis in a mailed survey to elicit preferences based on clinical vignettes from surgeons, FPs and patients. A Delphi expert panel provided consensus guideline recommendations for surgical referral to compare with actual FP referral practices. Rates of surgery for DDLS, obtained from Ontario hospital discharge data, were used to quantify regional variation and regression models assessed the relationship with patient and physician enthusiasm. We identified significant differences in preferences for referral and surgery between patients, FPs and surgeons. Surgeons placed high importance on leg-dominant symptoms while patients had high importance for quality of life symptoms (i.e. severity, duration, walking tolerance). Surgical referral practices were poorly predicted by individual FP preferences and guideline recommendations based on clinical factors alone. Variation in Ontario surgical rates was higher than that of hip or knee replacements and was highly associated with the enthusiasm of surgeons (p<0.008), rather than FPs or patients. By appreciating the variation in preferences between patients and physicians, and exploring other non-clinical factors that influence referrals, we may be able to improve the efficiency of referrals and enhance the shared decision making process. With an understanding of the influence that surgeons have in driving variation in surgical rates, further research may allow us to direct strategies to improve access and allow for a more equitable delivery of care for patients suffering from DDLS.

This dissertation is composed of two essays that examine the role of public and private health insurance on healthcare access, use, and cost containment. In Chapter 1, Dugan, Virani, and Ho examine the impact of Medicare eligibility on healthcare utilization and access. Although Medicare eligibility has been shown to generally increase health care utilization, few studies have examined these relationships among the chronically ill. We use a regression-discontinuity framework to compare physician utilization and financial access to care among people before and after the Medicare eligibility threshold at age 65. Specifically, we focus on coronary heart disease and stroke (CHDS) patients. We find that Medicare eligibility improves health care access and physician utilization for many adults with CHDS, but it may not promote appropriate levels of physician use among blacks with CHDS. My second chapter examines the extent to which the managed care backlash affected managed care's ability to contain hospital costs among short-term, non-federal hospitals between 1998 and 2008. My analysis focuses on health maintenance organizations (HMOs), the most aggressive managed care model. Unlike previous studies that use cross-sectional or fixed effects estimators to address the endogeneity of HMO penetration with respect to hospital costs, this study uses a fixed effects instrumental variable approach. The results suggest two conclusions. First, I find the impact of increased HMO penetration on costs declined over the study period, suggesting regulation adversely impacted managed care's ability to contain hospital costs. Second, when costs are decomposed into unit costs by hospital service, I find the impact of increased HMO penetration on inpatient costs reversed over the study period, but HMOs were still effective at containing outpatient costs.
