The Use of Podcasts in Education

Background: The use of podcasts has emerged as an important tool for use in education. This is especially relevant in nursing schools with the shortage of nursing faculty. The use of podcasts allows the instructor to provide lectures and other course content to students. [See PDF for complete abstract]

Exploring the use of pharmaceutical patient assistance programs as an option to improve access to and affordability of prescription drugs

Background. Pharmaceutical-sponsored patient assistance programs (PAPs) are charity programs that provide free or reduced-priced medications to eligible patients. PAPs have the potential to improve prescription drug accessibility for patients but currently there is limited information about their use and effectiveness. ^ Objectives and methods. This dissertation described the use of PAPs in the U.S. through the conduct of two studies: (1) a systematic review of primary studies of PAPs from commercially-published and “grey” literature sources; and (2) a retrospective, cross-sectional study of cancer patients' use of PAPs at a tertiary care cancer outpatient center. ^ Results. (1) The systematic review identified 33 studies: 15 evaluated the impact of PAP enrollment assistance programs on patient healthcare outcomes; 7 assessed institutional costs of providing enrollment assistance; 7 surveyed stakeholders; 4 examined other aspects. Standardized mean differences calculated for disease indicator outcomes (most of which were single group, pre-posttest designs) showed significant decreases in glycemic and lipid control, and inconsistent results for blood pressure. Grey literature abstracts reported insufficient statistics for calculations. Study heterogeneity made weighted summary estimates inappropriate. Economic analyses indicated positive financial benefits to institutions providing enrollment assistance (cost) compared to the wholesale value of the medications provided (benefit); analyses did not value health outcomes. Mean quality of reporting scores were higher for observational studies in commercially-published articles versus full text, grey literature reports. (2) The cross-sectional study found that PAP outpatients were significantly more likely to be uninsured, indigent, and < 65 years old than non-PAP patients. Nearly all non-PAP and PAP prescriptions were for non-cancer conditions, either for co-morbidities (e.g., hypertension) or the management of treatment side effects (e.g., pain). Oral chemotherapies from PAPs were significantly more likely to be for breast versus other cancers, and be a newer, targeted versus traditional chemotherapy.^ Conclusions. In outpatient settings, PAP enrollment assistance plus additional medication services (e.g., counseling, reminders, and free samples) is associated with improved disease indicators for patients. Healthcare institutions, including cancer centers, can offset financial losses from uncompensated drug costs and recoup costs invested in enrollment assistance programs by procuring free PAP medications. Cancer patients who are indigent and uninsured may be able to access more outpatient medications for their supportive care needs through PAPs, than for cancer treatment options like oral chemotherapies. Because of the selective availability of drugs through PAPs, there may be more options for newer, oral, targeted chemotherapies for the treatment breast cancer versus other for other cancers.^

A project to improve the information seeking skills and increase the use of evidence-based research in public health practice

The ability of public health practitioners (PHPs) to work efficiently and effectively is negatively impacted by their lack of knowledge of the broad range of evidence-based practice information resources and tools that can be utilized to guide them in their development of health policies and programs. This project, a three-hour continuing education hands-on workshop with supporting resources, was designed to increase knowledge and skills of these resources. The workshop was presented as a pre-conference continuing education program for the Texas Public Health Association (TPHA) 2008 Annual Conference. Topics included: identification of evidence-based practice resources to aid in the development of policies and programs; identification of sources of publicly available data; utilization of data for community assessments; and accessing and searching the literature through a collection of databases available to all citizens of Texas. Supplemental resources included a blog that served as a gateway to the resources explored during the presentation, a community assessment workbook that incorporates both Healthy People 2010 objectives and links to reliable sources of data, and handouts providing additional instruction on the use of the resources covered during the workshop.^ Before- and after-workshop surveys based on Kirkpatrick's 4-level model of evaluation and the Theory of Planned Behavior were administered. Of the questions related to the trainer, the workshop, and the usefulness of the workshop, participants gave "Good" to "Excellent" responses to all one question. Confidence levels overall increased a statistically significant amount; measurements of attitude, social norms, and control showed no significant differences before and after the workshop. Lastly, participants indicated they were likely to use resources shown during the workshop within a one to three month time period on average. ^ The workshop and creation of supplemental resources served as a pilot for a funded project that will be continued with the development and delivery of four 4-week long webinar-based training sessions to be completed by December 2008. ^

The use of the computerized and revised vital record in conducting etiologic studies on neural tube defects

The purpose of this study was to evaluate the adequacy of computerized vital records in Texas for conducting etiologic studies on neural tube defects (NTDs), using the revised and expanded National Centers for Health Statistics vital record forms introduced in Texas in 1989.^ Cases of NTDs (anencephaly and spina bifida) among Harris County (Houston) residents were identified from the computerized birth and death records for 1989-1991. The validity of the system was then measured against cases ascertained independently through medical records and death certificates. The computerized system performed poorly in its identification of NTDs, particularly for anencephaly, where the false positive rate was 80% with little or no improvement over the 3-year period. For both NTDs the sensitivity and predictive value positive of the tapes were somewhat higher for Hispanic than non-Hispanic mothers.^ Case control studies were conducted utilizing the tape set and the independently verified data set, using controls selected from the live birth tapes. Findings varied widely between the data sets. For example, the anencephaly odds ratio for Hispanic mothers (vs. non-Hispanic) was 1.91 (CI = 1.38-2.65) for the tape file, but 3.18 (CI = 1.81-5.58) for verified records. The odds ratio for diabetes was elevated for the tape set (OR = 3.33, CI = 1.67-6.66) but not for verified cases (OR = 1.09, CI = 0.24-4.96), among whom few mothers were diabetic. It was concluded that computerized tapes should not be solely relied on for NTD studies.^ Using the verified cases, Hispanic mother was associated with spina bifida, and Hispanic mother, teen mother, and previous pregnancy terminations were associated with anencephaly. Mother's birthplace, education, parity, and diabetes were not significant for either NTD.^ Stratified analyses revealed several notable examples of statistical interaction. For anencephaly, strong interaction was observed between Hispanic origin and trimester of first prenatal care.^ The prevalence was 3.8 per 10,000 live births for anencephaly and 2.0 for spina bifida (5.8 per 10,000 births for the combined categories). ^
