All things bed bugs: a primer for Nephrology Nurses.
Bed bugs are also a potential problem in nephrology patient settings. Members of the American Nephrology Nurses Association (ANNA) across the country have been writing and asking about bed bug treatment and protocols in the ANNA Open Forum since 2011. A search of ANNA Connected with the search term 'bed bugs' revealed 32 results.
Infestations on the Rise
Bed bugs may be found anywhere there is a sleeping human body and can travel up to 100 feet on their own to find a host. There was a dramatic drop in bed bug infestation in the 1950s due to the development of dichlorodiphenyltrichloroethane (DDT), but the country has seen a resurgence since the 1990s (Thomas, Wrobel, & Brown, 2013). The 2011 Bugs Without Borders Survey conducted by the National Pest Management Association (2017) revealed that 99% of pest management professionals encountered bed bug infestations, compared to 11% more than 10 years ago. The Orkin pest control company publishes an annual list of the top 50 bed bug cities based on bedbug treatments and inspections (Orkin, 2017). The 2016 list is based on residential and commercial treatment data from the metro areas where Orkin performed the most bed bug treatments from December 1, 2015, to November 30, 2016. The top 10 cities in rank order were (the number in parentheses is the change in rank since 2015):
1. Baltimore (+9)
2. Washington, D.C. (+1)
3. Chicago (-2)
4. New York
5. Columbus, Ohio
6. Los Angeles (-4)
9. Philadelphia (-3)
10. San Francisco-Oakland-San Jose (+4)
Typically, bed bugs live in a 5- to 20-foot area from the host, but can be found up to 100 feet away. Bed bugs like to hide in clothing and crevices, and are easily transported from one location to another in clothing, travel bags, and backpacks, promoting their spread to new locations. Bed bugs are sometimes transferred from one location to another in non-clothing/luggage articles, such as boxes, computers, and toys. Adult bed bugs can live for over one year and lay over 500 eggs in their lifetime. There are five stages in the bed bug lifecycle, and blood is needed at each stage (see Figure 1). In addition to a blood source, bed bugs must shed their outer skin (molt) to progress to the next stage. It is this dead skin that often indicates a bed bug infestation.
Bed Bug Bites
Bed bugs locate their victim through detection of heat, body odor, and carbon dioxide (Center for Invasive Species Research, University of California, Riverside, 2016) and typically bite when people are in their deepest sleep, either late at night or early in the morning (Michigan Department of Community Health, 2010). The saliva of the bed bug contains an anesthetic and an anticoagulant, so the individual is not aware of the bite (Williams & Willis, 2012). Bed bugs typically feed every three to seven days, but can survive for up to a year without eating (National Pesticide Information Center, n.d.; Thomas et al., 2013). While some individuals may develop an allergic reaction to the bite, the typical presentation may be delayed for days or weeks, and ranges from small reddened areas to itchy raised welts (Thomas et al, 2013). Secondary infections may develop as a result of bed bug bites, requiring treatment with antihistamines, corticosteroids, or antibiotics (Rossi & Jennings, 2010, Williams & Willis, 2012). Of note, there is no documented evidence of disease transmission from bed bugs to humans (Lai et al., 2016).
The key to preventing further outbreaks of bed bugs is to recognize the signs of infestation and control the further spread of bed bugs. Tips to prevent and control bed bugs are shown in Table 1.
The elimination of bed bugs is complex and multifaceted.
Washing infested bed linens and clothing in very hot water and drying for 30 minutes in a hot dryer can kill bed bugs.
Using encasements on both the mattress and box springs will trap the bed bugs so they cannot reach the host. Without food, they will die.
Dispose of Infested Items
Wrap the infested items in plastic and label it is infested with bed bugs, so others do not take the item and spread the infestation.
Bed bugs cannot survive when their body temperature is greater than 113[degrees]F. Special equipment that provides dry, convection heating with temperatures greater than 120[degrees]F for several hours can be effective in killing bed bugs. Steam treatments with contact time of approximately 20 seconds per linear foot can kill bed bugs, but only where the steam can reach the bugs.
"Bed bugs can recover from being frozen if not subjected to temperatures low enough or for long enough" (Michigan Department of Community Health, 2010, p. 41), so it is important to adhere to established guidelines when using freezing techniques to reach 0[degrees]F. "Studies have shown that freezing bed bug infested items at less than 0[degrees] F for two or more hours is effective" (Michigan Department of Community Health, 2010, p. 41).
Bug bombs do not kill bed bugs. Chemicals that kill cockroaches will kill bed bugs, but bed bugs are becoming resistant to insecticides. According to the EPA (2016b), there are over 300 registered products in seven categories that will kill bed bugs: Pyrethrins, pyrethroids, dessicants, biochemical, pyrroles, neonicotinoids, and insect growth regulators. The categories and their descriptions are as follows (EPA, 2016b).
Pyrethrins and pyrethroids. Pyrethrins and pyrethroids are the most common pesticides used to kill bed bugs. Pyrethrins are derived from chrysanthemum flowers, and pyrethroids are chemical synthetics that are similar to Pyrethrins.
Dessicants. Dessicants destroy the wax outer coating of the bed bug, causing it to dehydrate and die. Boric acid is an example of a dessicant.
Biochemicals. "Cold pressed neem oil is the only biochemical pesticide registered for use against bed bugs. Cold pressed neem oil is pressed directly from seeds of the Neem tree, a tropical evergreen tree found in Southeast Asia and Africa. The oil contains various compounds that have insecticidal and medicinal properties. It is also used in making products, including shampoos, toothpaste, soaps, and cosmetics. Performance trials conducted at the approved label rates show both products control bed bug adults, nymphs, and eggs" (EPA, 2016b, Biochemicals).
Pyrroles. Chlorfenapyr is the only approved pyrrole for use. It is a pro-insecticide that is dependent on activation to become a new chemical that disrupts the bed bug cell structure, causing it to die.
Neonicotinoids. "Neonicotinoids are synthetic forms of nicotine and act on the nicotinic receptors of the nervous system by causing nerves to fire continually until they fail" (EPA, 2016b, Neonicotinoids).
Insect growth regulators. These growth regulators mimic juvenile growth hormones in insects. They either affect the bed bug's outer hard shell, preventing development into adulthood, or cause the bed bug to develop too rapidly.
Roles of Nephrology Nurses
Nephrology nurses have key support and advocacy roles in preventing and eliminating bed bug infestations.
Nephrology nurses are key to keeping the unit, staff, and patients panic-free. Recognizing signs of an infestation and having an awareness of unit protocol is essential. Nephrology nurses are instrumental in assessing and addressing the psychosocial impact of the bed bug infestation on the patient. Having an awareness of and comfort with anxiety and depression screening tools enable the nurse to assess the psychological burden to the patient.
Many hospitals and healthcare organizations have policies concerning the prevention and elimination of bed bug infestations; however, no guidelines or position statements regarding bed bugs in hemodialysis units were found, nor were any found in nephrology-related organizations, including the Renal Physicians Association, ANNA, or the End-Stage Renal Disease Networks. Nephrology nurses can lead the way for guideline and/or position statement development related to bed bugs, and impact policy at the local, association, and government levels.
Bed bugs are a public health concern that cause significant psychosocial and economic burden to individuals, healthcare facilities, and government agencies. Bed bug infestations can be avoided with diligent patient screening and awareness of signs of infestation. Non-chemical and chemical methods of eradication are effective, if used appropriately. Nephrology nurses play a key role in advocacy, policy/guideline development, and psychological support for patients and coworkers in the prevention and elimination of bed bugs in nephrology settings.
