Approximately eight billion therapeutic injections are administered outside of medical treatment facilities annually. The management of diabetes mellitus (DM) includes self-monitoring of blood glucose levels and administration of insulin and injectable non-insulin-related medications. The lancets, needles, and syringes used for DM management are categorized as medical sharps. Improperly discarded medical sharps can cause needlestick injuries in unsuspecting individuals and thereby pose a considerable public health risk. Release of these items into the environment will likely increase with the rising worldwide prevalence of DM, and a public safety crisis will emerge if proper disposal measures are not emphasized. This article reviews the literature from various geopolitical regions and describes how a substantial number of patients with DM improperly discard their sharps. Data support the need to develop multifaceted and innovative approaches to reduce risk associated with improper disposal of DM-related medical sharps into local communities.

Background: Every day, more than 190 people in the United States die from opioid overdose. Unused opioid medications pose a risk to the patient and the community as they increase the potential for abuse or misuse. A contributing factor is lack of education on the proper disposal methods of unused opioid medications.
Purpose: The purpose of this quasi-experimental nursing study was to examine whether providing education on proper disposal of opioid medications would increase the proportion of patients who properly dispose of unused opioids.
Methods: The study site's mandatory orthopaedic preoperative class was used for consenting patients. The control group did not receive targeted education on opioid disposal, whereas the intervention group did receive targeted education. A total of 86 patients were consented during Months 1 and 2 of the study. Forty-one patients were in the control group and 45 were in the intervention group. Demographic variables such as age, gender, and marital status were collected to determine whether certain demographic factors had an influence over whether or not opioids would be disposed of properly.
Findings: Those in the intervention group who attended the class were slightly younger than those in the control group (68.2 ± 9.9 years vs. 70.3 ± 10.6 years, p = .5098), primarily male (57.5% vs. 35.0%, p = .0436), and more likely to live with a significant other (94.7% vs. 74.4%, p = .0249). Of those who had medication left over, 62.5% disposed of their unused opioid prescription in the intervention group compared with 40.7% in the control group (p = .1208). In the intervention group, 86.7% of the individuals with leftover medication disposed of it correctly compared with 63.5% in the control group (p = .3478).
Conclusion: Those who received education on appropriate opioid disposal were more likely to dispose of it in general as well as dispose of it correctly. Although not statistically significant, the findings from this study are clinically significant in that they provide direction on the importance of standardized and focused patient education on proper opioid disposal.

Background: The objective of this study was to assess disposal patterns for "sharps" among a cohort of patients with diabetes mellitus (DM) receiving insulin therapy.
Method: A convenience sample of inpatients and outpatients was surveyed about how they disposed of sharps, how often they reused lancets and needles, and what education they had received about proper disposal. Safe disposal was defined as discarding sharps into a formal sharps or sealable container; otherwise, disposal was categorized as unsafe.
Results: Of 150 respondents, 56% were men and 75% were white. The mean (SD) age was 56 (15) years; duration of DM, 20 (13) years; and hemoglobin A1c, 8.1% (2.0%). Half the respondents reused a lancet two or more times, and 21% reused an insulin needle two or more times. Thirty-eight percent of respondents discarded lancets unsafely, and 33% discarded insulin needles unsafely, typically by throwing these items into household trash. Most respondents (75%) discarded insulin pens, vials, cartridges, insulin pump supplies, and continuous glucose monitor sensors into household trash. Most (64%) indicated that they had not received education on safe sharps-disposal practices, and 84% had never visited their municipal website for information on medical waste disposal.
Conclusion: Approximately one-third of patients unsafely disposed of sharps. Unsafe disposal could cause millions of sharps to appear in the municipal solid waste stream, thereby posing a substantial public health hazard. Point-of-care patient education is important, but a broader public health campaign may be required.

One-fourth of all operating room (OR) waste is attributed to anesthesia-related material. The goal of this project was to reduce the waste and increase cost savings of opened and unused endotracheal (ET) tubes and disposable laryngoscope handles and blades in 2 separate OR environments. The production of these unused anesthesia supplies was assessed weekly in each of 2 OR environments for 8 weeks before an educational intervention, and for 8 weeks following the intervention. The average weekly waste production was summarized for each study period, compared between periods (preintervention vs postintervention), and analyzed per 100 surgeries using the 2-sample t test. The overall average weekly waste for ET tubes was significantly reduced from 26.7 ± 10.7 to 10.0 ± 6.1 from pre to post intervention (P = < .001), representing a 62.6% reduction. A similar significant reduction in waste was observed for laryngoscope handles (15.9 ± 8.1 vs 7.2 ± 3.1; P = .004; a 54.7% reduction) and laryngoscope blades (21.5 ± 11.0 vs 9.9 ± 4.4; P = .004; a 54.0% reduction). These results highlight the significance and feasibility of an educational intervention in reducing the environmental and economic waste produced by anesthetic practices in the OR.

Operating rooms generate 42% of a hospital's revenue and 30% of hospital waste. Supply costs are 56% of a total operating room (OR) budget. US academic medical centers use 2 million pounds ($15 million) of recoverable medical supplies annually. Forming a multidisciplinary leadership team, we analyzed sources of waste focusing on our Department of Neurosurgery. We developed an 8-wk pilot project to recycle "blue wrap," the number 5 plastic polypropylene material that is ubiquitously used in ORs across the country to wrap instrument pans and implant trays for sterilization. Blue wrap can be baled and sold to recyclers where the material is pelletized and transformed into plastic products. During the 39 d of the pilot, we collected 1247 pounds of blue wrap (32 lbs collected daily). The cost of the pilot was $14 987 that includes a new baler ($11 200) and 5 transport carts ($3697). The revenue received from baled blue wrap was 8 cents per pound. Cost avoidance yielded $31 680.00 in savings. Implementation of this pilot across our main hospital would yield $5000 in revenue annually and $174 240 in cost avoidance. This project can be replicated at other centers and not only reduces the environmental footprint, but also helps generate additional revenue by recycling a necessary packing material that would otherwise require payment for disposal.
