Does Cost Influence the Choice of Disposable Versus Reusable Instruments? Mailed Survey of...

A "cost-awareness" campaign was undertaken at a tertiary hospital from 2015 to 2016 to raise awareness about costs of disposable versus reusable instruments in laparoscopic procedures. We undertook a before and after survey of obstetrician/gynecologists (Ob/Gyns) to find out if the campaign had affected their attitudes about choosing disposable versus less expensive reusable instruments.

In 2015 (before the cost-awareness campaign) and 2017 (after the cost-awareness campaign), all full-time university-associated Ob/Gyns were mailed a cover letter, questionnaire, and coffee card ($5) with a postage-paid return envelope. Responses (with unique identification) from Ob/Gyns who perform laparoscopic procedures were entered into a password-protected REDCap database on a secure server. All statistical analyses were performed using SAS software version 9.4 (SAS Institute Inc, Cary, NC) (Canadian Task Force Classification II-3).

A total of 35 of 42 eligible Ob/Gyns (85%) with a median 10 years in practice completed questionnaires before and after the intervention. The majority had undertaken minimally invasive surgery training, mainly during residency (80%) and conferences (71%). Before the intervention, the three most important qualities influencing their decision to use a particular instrument were safety (66%), effectiveness (57%), and personal experience (49%). After the intervention, the three most important qualities were effectiveness (57%), safety (57%), and ease of use (46%). Device cost was ranked sixth (26%) before and seventh (17%) after the intervention. The majority (57%) of participants did not change their choice of disposable or reusable instruments, or they would make the choice according to the specific procedure.

Given the current economy, operative costs are constantly under review. Knowledge about Ob/Gyns' attitudes provides information to design more effective awareness campaigns to encourage use of less costly instruments. To change practice, a campaign increasing Ob/Gyns' exposure to less expensive but safe and effective instruments may help to increase uptake and potentially lead to cost reduction. Cost awareness alone is unlikely to change practice.
