Implementation and maintenance of patient navigation programs linking primary care with community-based health and social services: a scoping literature review.

BACKGROUND: Since the early 90s, patient navigation programs were introduced in the United States to address inequitable access to cancer care. Programs have since expanded internationally and in scope. The goals of patient navigation programs are to: a) link patients and families to primary care services, specialist care, and community-based health and social services (CBHSS); b) provide more holistic patient-centred care; and, c) identify and resolve patient barriers to care. This paper fills a gap in knowledge to reveal what is known about motivators and factors influencing implementation and maintenance of patient navigation programs in primary care that link patients to CBHSS. It also reports on outcomes from these studies to help identify gaps in research that can inform future studies. METHODS: This scoping literature review involved: i) electronic database searches; ii) a web site search; iii) a search of reference lists from literature reviews; and, iv) author follow up. It included papers from Canada, the United States, the United Kingdom, Australia, New Zealand, and/or Western Europe published between January 1990 and June 2013 if they discussed navigators or navigation programs in primary care settings that linked patients to CBHSS. RESULTS: Of 34 papers, most originated in the United States (n = 29) while the remainder were from the United Kingdom, Canada and Australia. Motivators for initiating navigation programs were to: a) improve delivery of health and social care services; b) support and manage specific health needs or specific population needs, and; c) improve quality of life and wellbeing of patients. Eleven factors were found to influence implementation and maintenance of these patient navigation programs. These factors closely aligned with the Diffusion of Innovation in Service Organizations model, thus providing a theoretical foundation to support them. Various positive outcomes were reported for patients, providers and navigators, as well as the health and social care system, although they need to be considered with caution since the majority of studies were descriptive. CONCLUSIONS: This study contributes new knowledge that can inform the initiation and maintenance of primary care patient navigation programs that link patients with CBHSS. It also provides directions for future research.

Use of self-prescribed nonprescription medications and dietary supplements among assisted living facility residents.

OBJECTIVE: Describe the prevalence of self-prescribed use and misuse as well as users' opinions concerning nonprescription medications and dietary supplements in assisted living facilities. DESIGN: Descriptive cross-sectional study. SETTING: Two assisted living facilities (ALFs) in Oregon and Washington State. PARTICIPANTS: Convenience sample of 45 ALF residents. INTERVENTION: Chart reviews and face-to-face interviews. MAIN OUTCOME MEASURES: Prevalence and types of use of self-prescribed over-the-counter (OTC) medications and dietary supplements; misuse of these products, and participants' opinions concerning use of these products. RESULTS: Among 29 women and 16 men with a mean (+/- SD) age of 84.8 +/- 6.9 years and a mean of 9.9 +/- 6.4 years of education, 84.4% were using selfprescribed OTC medications and dietary supplements at the time of this study. A mean of 3.4 products was used per participant. Nutritional supplements were most frequently used (32% of products), followed by gastrointestinal products (17%), pain relievers (16.3%), herbals (14.4%), topical products (12%), and cold/cough products (8.5%). Potential misuse was identified in 23 (51%) of the participants. Problems in the use of products included duplication (70%), potential drug/disease/food interactions (20.8%), and other inappropriate use (9.1%). The majority (76%) of the participants believed the products were helpful in maintaining health, 56% of them wanted more product information, 49% sought product information from family and friends, 40% turned to their physicians and nurses for information, and 11% asked pharmacists for advice. CONCLUSION: The use of nonprescription medications and dietary supplements among ALF residents was high, and simultaneous use of multiple products with the same active ingredient was the most prevalent problem. The residents turned to family and friends, physicians, nurses, and ALF staff for information on these products more frequently than they did to pharmacists.
