Quality improvement in chronic illness care: a collaborative approach.

BACKGROUND: Despite rapid advances in the clinical and psycho-educational management of diabetes, the quality of care received by the average patient with diabetes remains lackluster. The "collaborative" approach--the Breakthrough Series (BTS; Institute for Healthcare Improvement [IHI]; Boston)--coupled with a Chronic Care Model was used in an effort to improve clinical care of diabetes in 26 health care organizations. METHODS: Descriptive and pre-post data are presented from 23 health care organizations participating in the 13-month (August 1998-September 1999) BTS to improve diabetes care. The BTS combined the system changes suggested by the chronic care model, rapid cycle improvement, and evidence-based clinical content to assist teams with change efforts. The characteristics of organizations participating in the diabetes BTS, the collaborative process and content, and results of system-level changes are described. RESULTS: Twenty-three of 26 teams completed participation. Both chart review and self-report data on care processes and clinical outcomes suggested improvement based on changes teams made in the collaborative. Many of the organizations evidencing the largest improvements were community health centers, which had the fewest resources and the most challenged populations. DISCUSSION: The initial Chronic Illness BTS was sufficiently encouraging that replication and evaluation of the BTS collaborative model is being conducted in more than 50 health care systems for diabetes, congestive heart failure, depression, and asthma. This model represents a feasible method of improving the quality of care across different health care organizations and across multiple chronic illnesses.

Reducing adverse drug events: lessons from a breakthrough series collaborative.

BACKGROUND: In January 1996, 38 hospitals and health care organizations (for a total of 40 hospitals) in the United States came together in an Institute for Healthcare Improvement (IHI; Boston) Breakthrough Series collaborative to reduce adverse drug events-injuries related to the use or nonuse of medications. METHODS: The participants were taught the Model for Improvement, a method for rapid-cycle change and evaluation, and were then coached on how to identify their own problem areas and develop changes in practice for rapid-cycle testing. These changes could be implementation of one or more known medication error prevention practices or new practices developed. RESULTS: During a 15-month period the 40 hospitals conducted a total of 739 tests of changes. Process changes accounted for 63% of the cycles; the remainder consisted of preliminary data gathering, consensus-building, or education cycles. Eight types of changes were implemented by seven or more hospitals, with a success rate of 70%. These changes included non-punitive reporting, ensuring documentation of allergy information, standardizing medication administration times, and implementing chemotherapy protocols. DISCUSSION: Success in making significant changes was associated with strong leadership, effective processes, and appropriate choice of intervention. Successful teams were able to define, clearly state, and relentlessly pursue their aims, and then chose practical interventions and moved early into changing a process. They did not spend months collecting data before beginning a change. Changes that were most successful were those that attempted to change processes, not people. Health care organizations committed to patient safety need not regard current performance limits as inevitable.

Continuous quality improvement for patients with back pain.

Recent evidence has changed traditional approaches to low back pain, suggesting minimal bed rest, highly selective imaging, and early return to normal activities. However, there are wide geographical variations in care, and substantial gaps between practice and evidence. This project sought to merge scientific evidence about back pain and knowledge about behavior change to help organizations improve care for back pain. Participating insurance plans, HMOs, and group practices focused on problems they themselves identified. The year-long program included quarterly meetings, coaching for rapid cycles of change, a menu of potential interventions, and recommendations for monitoring outcomes. Participants interacted through meetings, e-mail, and conference calls. Of the 22 participating organizations, 6 (27%) made major progress. Typical changes were reduced imaging, bed rest, and work loss, and increased patient education and satisfaction. Specific examples were a 30% decrease in plain x-rays, a 100% increase in use of patient education materials, and an 81% drop in prescribed bed rest. Despite the complexity of care for back pain, rapid improvements appear feasible. Several organizations had major improvements, and most experienced at least modest improvements. Key elements of successful programs included focus on a small number of clinical goals, frequent measurement of outcomes among small samples of patients, vigilance in maintaining gains; involvement of office staffs as well as physicians, and changes in standard protocols for imaging, physical therapy, and referral.

Antibacterial activity of sucralfate versus aluminum chloride in simulated gastric fluid.

Studies have previously demonstrated that sucralfate possesses intrinsic antibacterial activity. This study was designed to indirectly assess whether aluminum is the active antibacterial component of sucralfate and to further evaluate factors that may influence this agent's antibacterial activity. Utilizing an in vitro model, the antibacterial activity of sucralfate, an equivalent quantity of aluminum in the form of aluminum chloride, and a control were compared. In addition, the influences of bacterial species (Enterobacter cloacae and Pseudomonas aeruginosa), time (0-24 h) and environmental pH (3,5,7) on the agents' antibacterial activities were evaluated. Equivalent quantities of aluminum, as either sucralfate or aluminum chloride, were added to two of three flasks containing approximately 10(5) cfu/ml of bacteria in pH-adjusted simulated gastric fluid. The third flask served as a control. Samples were obtained over 24 h, diluted and subcultured onto agar plates. The experiments demonstrated that bacterial growth was influenced by pH, time and treatment (aluminum chloride or sucralfate). Regardless of pH or bacterial species, bacterial death occurred within 20 min following the addition of aluminum chloride. In contrast, bacterial death following the addition of sucralfate was more variable and appeared to be pH dependent. In conclusion, sucralfate and aluminum chloride both possess antibacterial activity, even at pH values that normally support bacterial growth in gastric fluid. Although differences in the antibacterial activity of the two agents may in part be related to drug-induced changes in pH, these differences also support data suggesting that aluminum release from sucralfate is incomplete and is dependent on pH.

Basic principles of pharmacokinetics.

Pharmacokinetics can be used clinically to empirically describe the serum concentrations of drugs in the body. With a good understanding of the general principles utilized in predicting drug levels, the practitioner can understand the drugs and specific patient populations most likely to benefit from or need careful adjustment in therapeutic drug monitoring.
