Continuity of patient care is an essential element of primary care because it should result in better quality care and disease management, especially for older adults who often have multiple chronic illnesses. Even though continuity of care has been studied for decades, it remains difficult to define and quantify and, there is no consensus about best practices for assessing whether or not a patient experiences it or a practitioner provides it. Moreover, no theoretically-driven measures for the assessment of continuity of care exist, and there have been few rigorous evaluations of its association with subsequent health and health service utilization outcomes. The principal purpose of this dissertation research was to better understand continuity of care for older adults by identifying the components of the patient-provider relationship that are important from the patient perspective, understanding how commonly used provider-proxy continuity measures relate to the patient experience, and evaluating whether the patient experience or provider-proxy assessments are associated with improved health and health services utilization. I used survey data from the 2,997 Medicare beneficiaries who participated in the 2004 National Health and Health Services Use Questionnaire (NHHSUQ) linked to their Medicare claims for 2002-2009. The NHHSUQ contained patient-reported data on usual primary provider, usual place of care, and the quality and duration of the relationship with their provider. By linking this information to their Medicare claims, I was able to evaluate both patient-reported and provider-proxy (claims-based) measures of continuity of care from two years prior to the survey, and evaluate the impact of continuity on health and health service utilization for five years after the survey. Study results indicate that the older adult patient experience of continuity is reflective of both relationship duration and patient-provider interaction during the care visit, and that most provider-proxy continuity assessments did not relate to patient perceptions. And, the patient and provider-proxy experiences of continuity had different relationships with important health outcomes. These results enhance our understanding of continuity of care for older adults and inform policymakers and researchers about aspects of continuity that are important for the health of older adults and the appropriate use of health care resources.

The medical scheme industry in South Africa is competitive in relation to international standards. The medical scheme sector, as part of the healthcare industry, is negatively affected by the high rate of fraud perpetrated by providers, members and syndicates, which results in medical schemes funding fraudulent claims. The purpose of the study was to explore strategies to mitigate fraud in medical scheme claims. A qualitative research methodology was followed in this study, which adopted a case study approach. Empirical data was analysed through thematic analysis, with the aid of ATLAS.ti software. The study found that healthcare service providers mainly defraud medical schemes by submitting false claims. A holistic approach should be followed to mitigate fraud in medical scheme claims. This approach should encompass regularly identifying trends in fraudulent claims and implementing appropriate control strategies. Collaboration within the medical scheme industry and with other stakeholders would also help to elevate the fight against medical scheme fraud to a new level. Implementing the recommendations from the study will assist medical schemes to reduce the funds expended on fraudulent claims, thereby improving their financial viability and decreasing the rate of increase in medical scheme contributions for members. / Business Management / M.
