Project Aims

• Mandated by CA Senate Bill 2005;• Pilot study to determine the feasibility of

establishing a Sharps Injury Registry;• Overlapped passage of CA Assembly

Bill 1208 which mandated emergency changes to the Bloodborne Pathogens Standard.

Overview of Sharps Injury Surveillance Program

California the first state in the U.S. to develop a voluntary sharps injury registry

Collects data from acute care hospitals, home health agencies, and skilled nursing facilities.

Collected 1940 reports from 442 facilities (Jan. 98-Jan 30, 2000).

Response Rate

Overall response rate - 18%• Acute care facilities – 106/477 (22%)• Home health agencies – 120/872 (13%)• Skilled nursing facilities – 216/1177 (18%)

Average daily expenses in participating hospitals higher than non-participating hospitals (t = 2.55, p = 0.01)

Overall Project Aims

Conduct 2-year sharps injury surveillance study (injury registry)

Compile list of safety device studies Educate the public regarding sharps

injuries and Bloodborne pathogens Compile a list of available devices with

sharps injury prevention features

Research Methods

Developed injury log form for reporting Sent survey letter to 2550 California

acute care hospitals, skilled nursing facilities and home health care agencies requesting data

Sent follow up post card; second mailing Data coding, entry, cleaning and analyses

Study Parameters

Data was collected before and after effective date of revisions to California Bloodborne Pathogens standard

Sharps Injury Surveillance ProgramJanuary 1, 1998-December 31, 1999

Revisions to Bloodborne Pathogens Standard

Effective July 1999

Inclusion Criteria

Only includes injuries from sharp objects (not splashes, bites, or exposure to mucous membranes)

Only injuries from contaminated sharps Injuries to employees (not patients or

visitors)

Study Limitations

Participation was voluntary; data accepted in any format

Necessary to re-code data• Initial instructions not provided for log• Brand and model often unknown • Missing data in all data fields• Variability among facilities with regard to

data collection efforts considerable

Sharps Injury Log Form

Description of the Exposure Incident Job Classification Department or work area Procedure How the incident occurred

Sharps Injury Log Based on Cal-OSHA BBP Standard

Protective mechanism activated? Body part injured Employee’s opinion whether a safety

device or other controls could have prevented injury

Why Sharps Injury Surveillance?

Benefits of aggregated data Identify devices that continue to result in

injuries Serve as early warning for device or

design-related injuries Identify job class., procedures, work

activities, that continue to be at risk for sharps injuries.

Future Plans/Recommendations

Continue to collect sharps injury logs.

Encourage use of standard reporting format

Change voluntary nature of reporting

Develop recommendations based on injury circumstance and device type
