Failure of a continuous quality improvement intervention to increase the delivery of preventive services. A randomized trial.

CONTEXT: Although there has been enormous interest in continuous quality improvement (CQI) as a measure to improve health care, this enthusiasm is based largely on its apparent success in business rather than formal evaluations in health care. OBJECTIVE: To determine whether a managed care organization can increase delivery of eight clinical preventive services by using CQI. DESIGN: Primary care clinics were randomly assigned to improve delivery of preventive services with CQI (intervention group) or to provide usual care (control group). INTERVENTION: Through leadership support, training, consulting, and networking, each intervention clinic was assisted to use CQI multidisciplinary teams to develop and implement systems for delivery of preventive services. SETTING: 44 primary care clinics in greater Minneapolis-St. Paul. PATIENTS: Patients 19 years of age and older completed surveys at baseline (n = 6830) and at follow-up (n = 6431). Medical chart audits were completed on 4777 patients at baseline and 4546 patients at follow-up. MAIN OUTCOME MEASURES: The proportion of patients who were up-to-date (according to chart audit) and the proportion of patients who were offered a service if not up-to-date (according to patient report) for 8 preventive services. RESULTS: Compared with the control group, based on the proportion of patients who were up-to-date, use of only one preventive service--pneumococcal vaccine--increased significantly in the intervention group (17.2% absolute increase from baseline to follow-up compared with a 0.3% absolute increase in the control group, P = 0.003). Similarly, based on patient report of being offered a service if not up-to-date, delivery of only one preventive service--cholesterol testing--significantly increased in the intervention group compared with the control group (4.6% increase vs. 0.4% absolute decrease in the control group; P = 0.006). CONCLUSION: In this trial, CQI methods did not result in clinically important increases in preventive service delivery rates.

Promoting tobacco cessation in primary care practice.

Promoting tobacco cessation is an important part of the work of clinicians and staff in primary care practice. This article describes the significant public health impact of helping patients quit using tobacco through the use of an effective clinic-based intervention. The most effective strategies are to develop organization commitment, ask every patient about tobacco use at every visit and document it, advise all tobacco users to quit, assess readiness to quit, provide at least brief behavioral counseling, provide follow-up soon after quit date, conduct at least basic evaluations of each component of the process, and assess the quit rate for the practice as a whole.

Nurses on quality improvement teams: how do they benefit?

As part of a randomized control trial to improve the delivery of preventive services, the authors studied the effect on clinic nurses in the roles of team leaders or facilitators of multidisciplinary, continuous quality improvement (CQI) teams. Our goal was to learn how these nurses felt about their experience with this project, specifically their satisfaction with process improvement, acquired knowledge and skills, and the impact on their nursing role. Overall, the nurses involved in this study reported significant gains in all three areas. This study suggests that CQI can be a valuable vehicle for improving and expanding the nursing role for clinic nurses.

The case of the missing clinical preventive services systems.

OBJECTIVE: To examine the presence and comprehensiveness of organized processes and systems in a sample of primary care clinics shown to have high variation in rates of providing preventive services. DESIGN: Survey study. SETTING: 44 primary care clinics recruited for a scientific trial of a quality improvement intervention to improve preventive services. PARTICIPANTS: 647 clinicians and nurses. MEASUREMENTS: The presence of 10 organized prevention processes for eight adult preventive services as reported by those clinicians and nurses on a detailed written survey. RESULTS: In more than 50% of clinics, 7 of the 10 prevention processes were reported to be absent for all eight services. Only the follow-up process was commonly present; this was also the only process that was usually present for most applicable services. CONCLUSIONS: The paucity of recognizable organized processes to support the systematic delivery of adult preventive services in clinics with highly varying rates of providing these services supports the idea that lack of systems may be an important source of the variability and low rates. Most of the existing processes are fragmented and do not function across multiple preventive services.

Delivering clinical preventive services is a systems problem.

A steadily increasing number of research trials and prevention advocates are identifying the practice environment as the main source of both problems and solutions to the improved delivery of clinical preventive services. Although these sources are correctly focusing on office systems as solutions, there is a tendency to focus on only parts of a system and to relate this to just one or a few related preventive services. However, the effort required to set up and maintain an office system makes it difficult to justify doing so for a single clinical activity. The process and system thinking of Continuous Quality Improvement (CQI) theory suggests that there may be both efficiency and effectiveness advantages to the concept of all clinical preventive services being served by a single system with many interrelated component processes. Such a system should be usable for all age groups. This system and its literature base are described. The feasibility of applying this concept is being tested in a randomized controlled trial in 44 primary care clinics in Minnesota and Wisconsin.

Using continuous quality improvement to increase preventive services in clinical practice--going beyond guidelines.

BACKGROUND: Even the most uniformly accepted prevention guidelines do not by themselves lead to implementation or to adequate rates of preventive services in medical practice. Although much has been learned about the office systems that seem to be needed for major change in a busy clinical practice, there are still no examples of a model for developing, implementing, and sustaining those office systems in a nonacademic practice. METHODS: IMPROVE, the first large randomized controlled trial of CQI (continuous quality improvement) in any industry, is providing a scientific test of the hypothesis that HMO sponsorship of a CQI-based intervention can lead to sustained organizational change, implementation and maintenance of office systems, and improved rates of adult preventive services in contracted private primary care clinics. The 22 clinics assigned to the intervention arm of the study are receiving training, consultation, networking, and reinforcement for internal multidisciplinary teams as they work through a structured process to understand and improve their clinic's process for providing preventive services. Rates and quality of eight preventive services in these clinics are being compared over time with those in 22 matched comparison clinics. RESULTS: The 44 clinics needed for the trial have been recruited and randomized, and baseline comparisons show no significant differences between the two groups. Nine months into the trial, 21 of 22 intervention clinics have completed training and are pursuing a systematic improvement process for preventive services. CONCLUSIONS: With external training and consultation, many private primary care clinics will voluntarily engage in a lengthy multidisciplinary team effort to use CQI techniques to study and systematically improve their entire process for providing preventive services.

A controlled trial to integrate smoking cessation advice into primary care practice: Doctors Helping Smokers, Round III.

BACKGROUND: Although most physicians believe that smoking cessation assistance is important for their patients, the majority of smokers report that they have not received smoking cessation advice from a physician. We therefore tested whether on-site recruitment, training, and organizational assistance in incorporating a smoking intervention system of documented efficacy into nonvolunteer primary care practices would result in higher rates of smoking cessation advice to patients. METHODS: This was a nonrandomized trial comparing all 10 primary care clinics in an intervention area to all 8 primary care clinics from a geographically separate control area. The evaluation was based on the smoking intervention activities of each of the clinics as reported on preintervention and postintervention mail surveys of cohorts of regular smokers seen in the clinics. RESULTS: Preintervention, 22.9% +/- 11.2% of the intervention clinic cohort and 21.9% +/- 9.6% (P = .84) of the control clinic cohort reported that they had been asked about tobacco during a clinic visit in the prior 6 months. Postintervention, the intervention clinic cohort was significantly more likely to report that someone had asked them if they smoked (39.8% +/- 12.3% vs 26.0% +/- 12.2%; P less than .05), that their physician asked them to quit if they were currently smoking (40.5% +/- 12.1% vs 26.4% +/- 14.6%; P less than .05), and that someone had commended them if they had recently quit smoking (28.2% +/- 19.8 vs 11.3% +/- 11.8%; P less than .05). CONCLUSIONS: The intervention significantly increased the rates at which a population of primary care clinics identified their patients who smoked, advised them to quit smoking, and commended those who had recently quit smoking.
