Introduction Assessing the performance of medical institutions is critical to improving the quality of care provided to patients. Detailed assessment ensures that medical institutions understand their strengths and weaknesses and can take action required for enhancing the quality of service. The Joint Commission’s Annual Report is a document presenting the results of the regular quality assessment of American hospitals. This document is essential for gaining insight into how hospital performance is evaluated and compared. The present paper will outline some of the performance indicators used by the Joint Commission and describe the steps for gathering meaningful data on Aspirin on Arrival. Also, the essay will review the importance of comparing performance and explain the critical challenges of comparing data in the UAE. Process Indicators Process indicators are designed to determine the extent to which the facility adheres to evidence-based guidelines for promoting and maintaining patient health. According to the AHRQ (2015), “Process measures indicate what a provider does to maintain or improve health, either for healthy people or for those diagnosed with a health care condition” (para. 3). Process indicators can thus differ across diseases and units. For instance, PCI therapy within 90 minutes is among the main process indicators used for heart attack care measure (The Joint Commission 2014). This process indicator is based on clinical guidelines, as the use of PCI therapy for the treatment of heart attack is recommended to improve blood flow to the heart and prevent lasting damage. Another process indicator is antibiotics to ICU patients. This process indicator is applied in pneumonia care evaluation and is based on guidelines for managing pneumonia, which recommend the use of antibiotics. In surgical care, the use of antibiotics is also important in measuring processes. For instance, antibiotics within one hour before the first surgical cut is a vital process indicator applied to all types of surgeries (The Joint Commission 2014). The use of antibiotics is critical to preventing surgical site infections and is thus included in performance measures. Process indicators can also involve the use of other medications recommended for specific conditions. For instance, the Joint Commission (2014) includes systemic corticosteroids for inpatient asthma as one of the critical process indicators in children’s asthma care assessment. Lastly, influenza immunization is an important process measure that affects the overall quality of care in medical facilities. Outcome Indicators Outcome indicators are used to measure the results of care provided by the facility. According to the AHRQ (2015), “Outcome measures reflect the impact of the health care service or intervention on the health status of patients” (para. 5). The Joint Commission (2014) uses fewer outcome indicators than process indicators, as the former are often difficult to measure and may not reflect the quality of care correctly due to the influence of other factors. The incidence of potentially preventable VTE and newborn bloodstream infections are among the outcome indicators applied in the report. Physical restraint and seclusion are also included as outcome measures for inpatient psychiatric services, as these indicators can be influenced by effective therapy.
