Nutrition and Health for Older Persons in Rural America: A Managed Care Model

Health care services and resources for older persons living in rural areas may be highly variable, and integrated service-delivery models are often lacking. This article presents a managed-care model of nutrition risk screening and intervention for older persons in rural areas. Nutrition risk screening was implemented by the Geisinger Health Care System, Danville, Pa, to target all eligible enrollees in a regional Medicare risk program. A single remote clinic site participating in the managed health care system was chosen for further study of a linked screening and case-management effort for undernourished persons. Screening and intervention at the clinic site selected for this study were guided by centralized expertise and resources. Individualized evaluation and intervention plans were developed with the aid of a dietitian and implemented by the clinic case manager. Of the 417 subjects who completed screening at the remote site, 68 met the risk criteria for undernutrition and were selected for case management. Many of the targeted persons received interventions that included evaluations by a physician or physician extender (eg, physician assistant, nurse practitioner) at the clinic and consultations with nutrition, mental health, or social services professionals. Twenty-six of the subjects who took part in the intervention completed a follow-up screening 6 months later. Ten of those persons no longer exhibited risk criteria. This demonstrates the feasibility of a linked screening and case management program for nutrition risk in the managed-care setting. J Am Diet Assoc. 1997; 97: 885-888.     

The effect of acidic fibroblast growth factor and live yeast cell derivative on tympanic membrane regeneration in a rat model

The current treatment of choice for chronic tympanic membrane perforations is surgery. Recent studies using various polypeptide growth factors to accelerate closure of tympanic membrane perforations in model systems have produced mixed results. This study evaluates the effect of acidic fibroblast growth factor (AFGF) and live yeast cell derivative (LYCD) on the rate of healing of acute tympanic membrane perforations in a rat model. Thirty-seven rats had both ears separately randomized in a blinded fashion to receive AFGF in one of three concentrations, LYCD, or a control solution. The rats initially underwent subtotal removal of the tympanic membranes bilaterally. Solutions were applied to the randomized ears daily for 3 days, starting at the time of the surgical perforation. The ears were photographed every 3 to 8 days for 35 days. The photographs were digitally scanned and a computer analysis was used to calculate the percentage of residual perforation. No significant difference in the rate of healing was observed for ears treated with AFGF or LYCD versus the controls. Given the potential advantages of medical treatment of tympanic membrane perforations and the established efficacy of growth factors in other model systems, however, further research is warranted.

Using research results as a health promotion strategy: a five-year case study in Canada

Researchers in the field of health tend to share the resultsof their studies with colleagues by presenting papers and publishingin professional Journals. This practice is no longer adequateto promote major changes, as the infhiencers or agents of changesuch as senior administrators, elected officials and even thevoting public remain ignorant of the studies and their results.This article presents a case study of an effective, practicalhealth promotion strategy aimed at these agents of change. Itdescribes the planned, systematic dissemination of the resultsof two national surveys of the health knowledge, attitudes andbehaviour of schoolchildren in Canada. As a result, major influencesand changes have been documented in the development of programmes,resources and policies relevant to improved health educationin schools across Canada.     

The health promoting school: progress and future challenges in Welsh secondary schools

Data were obtained from a random sample of 87 secondary schoolsin Wales (UK) about the organization and provision of healtheducation teaching, the implementation of health related policies,and the involvement of outside agencies and professionals inthe planning and delivery of health education programmes. Theresults suggest that schools have made progress in curriculumdevelopment. However, if the concept of the health promotingschool is to be translated into practice, greater attentionwill need to be given us the development of broadly based policiesfor health covering both pupils and staff and the better integrationof school programmes with community resources. Greater understandingof the health promoting school concept by teaching staff andthe development of examples of good practice in embedding healtheducation into national curriculum subjects, are also advocated.
