A Review On Antibiotic Stewardship In Pediatric Primary Care, Paulina Kaminski

Public Health Theses

Background. Misuse of antibiotics for upper respiratory tract infections (URTIs) in pediatric primary care settings persists despite growing concern over antibiotic resistance. Interventions aimed at improving prescription use, coined Antibiotic Stewardship Programs (ASPs) often target clinicians for improved clinical decision-making. More recently, ASPs have begun educating patients to antibiotic needs, and for pediatric cases, parents who might pressure clinicians into prescribing unneeded antibiotics. While many reviews have targeted adult patients or emergency settings, few evaluate practices for pediatric populations. For this reason, we performed a review of the literature to summarize common strategies used to reduce antibiotic overprescribing for pediatric …

Old & Sexy: Investigating And Reducing Stigmatization Of Sexually-Active Older Persons, Samantha Nicole Levy

Public Health Theses

Media often portrays older persons as asexual or perversely sexual. This stigmatization may harm older persons’ sexual, mental, and physical health and well-being. As such, our study aimed to investigate the stigmatization of sexuality in later life and see if it can be reversed. Our four hypotheses included: (1) sexually-active older persons would be more stigmatized than sexually-inactive older persons; (2) negative age beliefs would predict stigmatization of sexually-active older adults; (3) participants would think more negatively about sexually-active older men compared to sexually-active older women; and (4) a brief writing intervention would help improve participants’ views towards sexually-active old …

An Analysis And Critique Of Mental Health Treatment In American State Prisons And Proposal For Improved Care, Shelby Hayne

Scripps Senior Theses
