Maine Medical Center Improves Patient Shower Safety Against Waterborne Illnesses

Innovative Shower System at Malone Family Tower Tackles Legionella Risk

Portland, ME – The Malone Family Tower at MaineHealth Maine medical Center – Portland (MHMMC-P) is setting a new standard for patient safety with the integration of an advanced shower drain system designed to combat waterborne pathogens, notably Legionella. This proactive approach addresses a critical vulnerability in healthcare facilities: stagnant water within shower systems.

The newly implemented system features a unique combination of a valve drain, diverter valve, and shower hose. This integrated design ensures that all 98 patient rooms are equipped to prevent water from pooling in pipes, valves, and shower hoses – common breeding grounds for Legionella bacteria.

According to the article’s source, the system automatically drains standing water within a minute of the shower being turned off.This includes the water column between the shower valve and the showerhead, as well as the one connecting to the hand-held shower spray.

“If you have Legionella in yoru system, you are at risk of growing it in stagnant water,” explained McDuff, reflecting the hospital’s commitment to patient safety. “When the plumbing representative mentioned this system with the self-draining valve, we specified it for the new facility. The assembly was easy to install.”

Beyond infection prevention, the shower drain system streamlines operations and enhances patient care by reducing manual tasks for hospital staff. “They don’t have to disconnect the shower hose,hang it,and let it dry before the next patient uses it,” McDuff stated. “This system ensures a seamless, hygienic experience.”

The shower system also boasts several additional features contributing to patient comfort and efficient water management. These include a hand spray with a pause control for assisted bathing and options for water flow rates of 2.5 GPM, 1.75 GPM, or 1.5 GPM. For accessibility and safety, the rooms are equipped with ADA-compliant grab bars and the fixtures meet stringent ASME, CSA, and ASSE standards.

MHMMC-P’s forward-thinking implementation of this shower drain technology underscores its dedication to comprehensive patient safety and infection control. While not mandated by current regulations, the hospital’s proactive stance aims to minimize the risk of hospital-acquired waterborne infections, ensuring patients recieve the highest standard of care. The system has reportedly performed flawlessly as its installation nearly a year ago, demonstrating its reliability and effectiveness.

What specific water quality parameters, beyond the presence of *Legionella*, *Pseudomonas aeruginosa*, and NTM, are included in MaineGeneral Health’s routine water testing protocols?

Understanding the Risk: Waterborne Pathogens in Healthcare Settings

Healthcare-associated infections (HAIs) remain a notable concern, and patient showers, while essential for hygiene, can sadly serve as breeding grounds for waterborne pathogens. Legionella, Pseudomonas aeruginosa, and non-tuberculous mycobacteria (NTM) are among the most common culprits, posing risks especially to immunocompromised patients. These bacteria thrive in warm,stagnant water and can be aerosolized during showering,leading to pneumonia,urinary tract infections,and wound infections. MaineGeneral Health in Augusta, ME, like many modern medical facilities, is proactively addressing these risks.

Proactive Measures Implemented by MaineGeneral Health

MaineGeneral Health (35 medical center Parkway, Augusta, ME 04330; 1-855-4MGH INFO) has implemented a multi-faceted approach to enhance patient shower safety, focusing on prevention, monitoring, and remediation. Key strategies include:

Water Management Plans: A complete water management plan is the cornerstone of their strategy. This plan details procedures for monitoring water quality, controlling biofilm formation, and responding to any identified contamination.

Regular Water Testing: Routine testing for legionella, Pseudomonas, and NTM is conducted in patient shower water systems. This allows for early detection of potential problems and prompt intervention. Testing frequency is based on risk assessment and regulatory guidelines.

Point-of-use Filters: Installation of point-of-use filters on showerheads provides an additional layer of protection, physically removing bacteria from the water before it reaches the patient. These filters are regularly maintained and replaced according to manufacturer recommendations.

Temperature Control: Maintaining consistent hot water temperatures above 140°F (60°C) throughout the plumbing system is crucial for inhibiting bacterial growth. MaineGeneral utilizes temperature monitoring systems to ensure compliance.

Showerhead Disinfection Protocols: Regular disinfection of showerheads, using approved methods, helps to reduce biofilm buildup and bacterial colonization.

Low-Flow Showerheads: Implementing low-flow showerheads not only conserves water but also reduces the potential for aerosolization of contaminated water.

The Role of Biofilm in Waterborne Illnesses

Biofilm – a slimy layer of microorganisms – is a major contributor to waterborne infections in healthcare settings. It forms on the inner surfaces of pipes and showerheads, providing a protective environment for bacteria.

Biofilm resistance: Bacteria within biofilm are substantially more resistant to disinfectants and antibiotics than free-floating bacteria.

Sloughing and Dispersal: Biofilm can periodically slough off, releasing bacteria into the water supply.

Regular Cleaning & Disinfection: Effective biofilm control requires a combination of regular cleaning, disinfection, and preventative measures like point-of-use filtration.

Advanced Monitoring Technologies

MaineGeneral Health is exploring and implementing advanced monitoring technologies to further enhance water safety:

Real-time Monitoring Systems: These systems continuously monitor water temperature, flow rates, and other parameters, providing immediate alerts if deviations occur.

Rapid Bacterial Detection: Utilizing rapid molecular testing methods allows for faster identification of pathogens, enabling quicker response times.

Digital Water Logs: Maintaining detailed digital records of water testing, maintenance activities, and corrective actions ensures accountability and facilitates trend analysis.

patient Populations at Highest Risk

Certain patient populations are particularly vulnerable to waterborne infections:

Immunocompromised Patients: Individuals with weakened immune systems (e.g., cancer patients, transplant recipients) are at increased risk of developing severe infections.

Patients with Chronic Lung Disease: Those with pre-existing lung conditions are more susceptible to Legionella pneumonia.

Patients with Open Wounds: Open wounds provide a direct entry point for bacteria.

Elderly Patients: Older adults often have reduced immune function and are more vulnerable to infection.

Benefits of Enhanced Shower Safety Protocols

Investing in robust shower safety protocols yields significant benefits:

Reduced HAI Rates: Lowering the incidence of healthcare-associated infections improves patient outcomes and reduces healthcare costs.

Improved Patient Safety: Protecting patients from preventable infections is a essential ethical obligation.

Enhanced Reputation: Demonstrating a commitment to patient safety enhances the hospital’s reputation and builds trust with the community.

Regulatory Compliance: Adhering to water safety guidelines ensures compliance with state and federal regulations.

Practical Tips for Healthcare Facilities

Beyond the measures implemented by MaineGeneral, other healthcare facilities can adopt these practical tips:

1. Develop a Comprehensive Water Management Plan: Tailor the plan to the specific needs of your facility.
2. Train Staff: Educate staff on proper shower cleaning and disinfection procedures.
3. Maintain Accurate Records: Keep detailed records of all water testing, maintenance, and corrective actions.
4. Regularly Inspect Plumbing Systems: Identify and address any potential sources of contamination.
5. Consider Point-of-use Filtration: Evaluate the feasibility of installing filters on showerheads.
6. Stay Updated on Best Practices: Continuously monitor evolving guidelines and technologies.
