Abstract

Aim. The purpose of this review of article is to assess the reuse of angioplasty devices as a challenge to the health center.

Background. Processing and reuse of disposable medical products began in the United States in 1970.

Method. Nowadays, infection is one of the common post-operative complications which have different severities and types based on social, financial and cultural conditions in different countries. Ignoring the proper disinfection and sterilization of hospital devices and equipment is one of the most important sources for distribution and transmission of nosocomial infections. The papers from 1998 to 2013 were searched for based on the key words "Reuse", "Single Use Only", "Disposable", "Medical Equipment", and "Reuse of Single Used Devices (SUD)" (alone or in combination) in Cumulative Index of Nursing and Allied Health Literature (CINAHL), Scopus, Medline, EMBASE, and PsycINFO.

Findings. The main problems in reusing angiography devices include the failure in cleaning, disinfection and sterilization of equipment due to structure design, lack of knowledge and not providing information  to patients and families regarding to reuse of  disposable devices, unclear  cost for the equipment, ambiguous disinfection and sterilization techniques for disposable medical equipment due to lack of proper staff supervision, lack of informed consent for reusing equipment, contradiction to the principles of clinical governance, patient safety, JCI standardization, and negligence of the ethical issues of patient care.

Conclusion. According to the lack of efficient reprocessing the angiography devices in country, lack of official license and policies issued by Ministry of Health and the Center of Medical Equipment, and the above mentioned risks, the reuse of these devices is not recommended.

Abstract
Aim. This study aimed to assess knowledge and practice of nurses about nursing care before and after cardiac catheterization
Background. The most common cause of death in most countries around the world is cardiovascular disease. Coronary angiography is an invasive procedure that is used to diagnose and/or treatment of coronary artery disease. Considering complications of cardiac catheterization, nursing care is of great importance in preventing and identifying complications. Standards are the least acceptable, expected and achievable levels of performance based on which it is possible to evaluate performance. Nurses and health care providers should work according to standard protocols.
Method. This descriptive analytical study was conducted on 65 nurses who were selected by census sampling method and based on inclusion criteria from cardiac catheterization wards of selected hospitals in Tehran, Iran. Data were collected by a questionnaire and a checklist prepared in accordance with the standards provided by the Ministry of Health and the Iranian Nursing Organization. The data were analyzed in SPSS version 21 using descriptive and inferential statistics.
Findings. Most of participants were female (63 percent). The mean score of knowledge about nursing care before and after angiography were 10.95±1.30 and 15.23±1.88, respectively. The mean score of performance about nursing care before and after angiography were 26.16±2.92 and 25.77±4.78, respectively; according to these findings the knowledge and practice of nurses about nursing care before and after angiography were evaluated as good. There was no statistically significant difference between female and male nurses in terms of knowledge and practice. Also, no statistically significant relationship was found between the knowledge and practice, before and after angiography.
Conclusion. Although most nurses had good scores of knowledge and practice about nursing care before and after angiography, but due to lack of some principles of care in their performance, further studies is recommended. Also, it is necessary for managers to provide nurses with care protocols.
