Using Lean to Rapidly and Sustainably Transform a Behavioral Health Crisis Program: Impact on Throughput and Safety.

BACKGROUND: Lean has been increasingly applied in health care to reduce waste and improve quality, particularly in fast-paced and high-acuity clinical settings such as emergency departments. In addition, Lean's focus on engagement of frontline staff in problem solving can be a catalyst for organizational change. In this study, ConnectionsAZ demonstrates how they applied Lean principles to rapidly and sustainably transform clinical operations in a behavioral health crisis facility. METHODS: A multidisciplinary team of management and frontline staff defined values-based outcome measures, mapped the current and ideal processes, and developed new processes to achieve the ideal. Phase I was implemented within three months of assuming management of the facility and involved a redesign of flow, space utilization, and clinical protocols. Phase II was implemented three months later and improved the provider staffing model. Organizational changes such as the development of shift leads and daily huddles were implemented to sustain change and create an environment supportive of future improvements. RESULTS: Post-Phase I, there were significant decreases (pre vs. post and one-year post) in median door-to-door dwell time (343 min vs. 118 and 99), calls to security for behavioral emergencies (13.5 per month vs. 4.3 and 4.8), and staff injuries (3.3 per month vs. 1.2 and 1.2). Post-Phase II, there were decreases in median door-to-doctor time (8.2 hours vs. 1.6 and 1.4) and hours on diversion (90% vs. 17% and 34%). CONCLUSIONS: Lean methods can positively affect safety and throughput and are complementary to patient-centered clinical goals in a behavioral health setting.

Crisis Reliability Indicators Supporting Emergency Services (CRISES): A Framework for Developing Performance Measures for Behavioral Health Crisis and Psychiatric Emergency Programs.

Crisis and emergency psychiatric services are an integral part of the healthcare system, yet there are no standardized measures for programs providing these services. We developed the Crisis Reliability Indicators Supporting Emergency Services (CRISES) framework to create measures that inform internal performance improvement initiatives and allow comparison across programs. The framework consists of two components-the CRISES domains (timely, safe, accessible, least-restrictive, effective, consumer/family centered, and partnership) and the measures supporting each domain. The CRISES framework provides a foundation for development of standardized measures for the crisis field. This will become increasingly important as pay-for-performance initiatives expand with healthcare reform.

The Banner psychiatric center: a model for providing psychiatric crisis care to the community while easing behavioral health holds in emergency departments.

Banner Health in the Phoenix, AZ, metropolitan area provides individuals in a behavioral health crisis with an alternative to presenting to an Emergency Department (ED). By implementing a process to quickly move patients out of our ED, our health care system has been able to greatly reduce the hold time for behavioral health patients. Through access to psychiatric clinicians around the clock at the Banner Psychiatric Center, patients now receive the appropriate treatment and needed care in a timely manner. Finally, disposition of patients into appropriate levels of care has freed up acute care Level 1 beds to be available to patients who meet those criteria.

Cholinergic-induced Ca2+ signaling in interstitial cells of Cajal from the guinea pig bladder.

Acetylcholine released from parasympathetic excitatory nerves activates contraction in detrusor smooth muscle. Immunohistochemical labeling of guinea pig detrusor with anti-c-Kit and anti-VAChT demonstrated a close structural relationship between interstitial cells of Cajal (ICC) and cholinergic nerves. The ability of guinea pig bladder detrusor ICC to respond to the acetylcholine analog, carbachol, was investigated in enzymatically dissociated cells, loaded with the Ca(2+) indicator fluo 4AM. ICC fired Ca(2+) transients in response to stimulation by carbachol (1/10 microM). Their pharmacology was consistent with carbachol-induced contractions in strips of detrusor which were inhibited by 4-DAMP (1 microM), an M(3) receptor antagonist, but not by the M(2) receptor antagonist methoctramine (1 microM). The source of Ca(2+) underlying the carbachol transients in isolated ICC was investigated using agents to interfere with influx or release from intracellular stores. Nifedipine (1 microM) or Ni(2+) (30-100 microM) to block Ca(2+) channels or the removal of external Ca(2+) reduced the amplitude of the carbachol transients. Application of ryanodine (30 microM) or tetracaine (100 microM) abolished the transients. The phospholipase C inhibitor, U-73122 (2.5 microM), significantly reduced the responses. 2-Aminoethoxydiethylborate (30 microM) caused a significant reduction and Xestospongin C (1 microM) was more effective, almost abolishing the responses. Intact in situ preparations of guinea pig bladder loaded with a Ca(2+) indicator showed distinctively different patterns of spontaneous Ca(2+) events in smooth muscle cells and ICC. Both cell types responded to carbachol by an increase in frequency of these events. In conclusion, guinea pig bladder detrusor ICC, both as isolated cells and within whole tissue preparations, respond to cholinergic stimulation by firing Ca(2+) transients.
