Public health services are population focused. In other words, public health services are provided to improve and promote the health status of the population (1). To accomplish this mission, in the United States, public health systems are structured to balance three core public health functions, i.e., assessment, policy development and assurance (1). Policy development, as one of the core functions of public health, is a process by which agencies collaborate with community components, planing and developing policies to address the priority health needs of the community. (1) During the past decade, a large number of strategic public health programs have been developed to improve quality pharmaceutical care being delivered. As an illustration, among many public health programs, the hospital antibiotic stewardship programs have been developed by pharmacists and physicians to maximize therapeutic outcomes (2). These programs optimize antimicrobial therapy while minimizing unintended consequences of antimicrobial use, including toxicity, and the emergence of resistance (2). These educational and community-based programs have remarkably contributed to improvement of public heath, proven highly successful in improving antibiotic use among patients with infectious diseases (3). …show more content…

    Essay On Contact Precautions

    During my clinical rotation at Palmetto Richland on the Acute Care for the Elderly unit there were several patients on contact precautions due primarily to Methicillin-resistant Staphylococcus aureus (MRSA) or high counts of gram-positive Escherichia coli bacterium (E. coli) in the urine and blood. A good example of best practice that I witnessed was the proper display and implementation of contact precautions around patients with multidrug-resistant organisms and bacteria (MDROs). If a patient is placed on contact precautions on this ACE unit floor, a large blue hanging bag, called an isolation precaution bag, is hung outside their room containing gloves and gowns. The nurse is to put on the glove and gown before entering the room and making contact with the patient.…

    Overprescribe Continuing Research

    Strategies Raising awareness (3) among the public and healthcare professionals through campaigns and events can help to educate people to the risks of antibiotic resistance and measures they can take to reduce the risk of it. Since 2008 there has been an European Antibiotic awareness day each year which has been found to be not only successful in raising awareness and changing the behaviour of healthcare professionals and the public in the way that they handle antibiotics but it was also quite cost effective. Ensuring GPs prescribe antibiotics responsibly to patients through providing resources to help them can help to reduce the over prescription of antibiotics. In 2012 the Health Protection Agency developed a tool called TARGET which would assist GPs in the proper use of antibiotics. Recently the National Institute for Healthcare Excellence has introduced new guidelines (4) to reduce over prescription.…

    Health Care Acquired Infection Paper

    Health care-acquired infection (HCAI) is a foremost problem for patient safety and its surveillance. Prevention of HCAI has got to be the first main concern for settings and institutions dedicated to making health care safer.
