WESTERN STATE HOSPITAL ASSAULT DATA OVER TIME Conducted by the Quality Management Department At Western State Hospital Overview of Topics  Examination of the statistical significance of assault data (patient-to-staff/patient assaults and assault-related injuries) over time hospital-wide  Examination of the statistical significance of assault data (patient-to-staff/patient assaults and assault-related injuries) over time by center  Examination of the statistical significance of assault data (patient-to-staff/patient assaults) over time by ward Document Reference: Theresa M Becker, Ph.D., Research Investigator 3 Department of Quality Management; Research, Evaluation, and Data Analysis 07.14.15 Definition of AROI Physical Assaults  Patient-to-Staff Physical Assault:   an alleged incident of intentional, negative physical contact or assault upon a staff person by a patient, with or without bodily harm. Patient-to-Patient Physical Assault:  physical abuse as defined by physical contact, with or without bodily harm, that involved the patient’s body and that was harmful to or jeopardized the safety and welfare of the patient, including squeezing, pinching, slapping, striking, pushing, and the use of excessive force. Document Reference: Theresa M Becker, Ph.D., Research Investigator 3 Department of Quality Management; Research, Evaluation, and Data Analysis 07.14.15 Method of Analysis  Linear Regression of Assault Data over Time  Please note:   1) This analysis is a starting point for examining the statistical significance of increases and decreases in hospital, center, and ward assault data over time 2) Additional analyses will be conducted in the future using analysis methods that better account for fluctuations in the data over time Document Reference: Theresa M Becker, Ph.D., Research Investigator 3 Department of Quality Management;
