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.

Variation in clinical preventive services.

CONTEXT: Preventive services are not delivered at optimal rates in primary care settings, and the literature suggests that a systems approach is key to improvement. Studying variation among clinics could help us to understand the extent of system use in practice. PRACTICE PATTERN EXAMINED: The proportion of patients who are up-to-date for preventive services in 44 primary care practices in the Midwest. PREVENTIVE SERVICES EXAMINED: Papanicolaou (Pap) smear, cholesterol testing, mammography, clinical breast examination, blood pressure measurement, influenza and pneumococcal vaccinations, and advice on tobacco use. DATA SOURCE: 6830 patients surveyed after their clinic visit (response rate, 85%). RESULTS: The proportion of patients up-to-date for preventive services varied widely among clinics. For example, up-to-date rates for Pap smear testing ranged from 70% to 93% and 45% to 88% for cholesterol screening. There was little correlation between a clinic's performance on one preventive service (relative to the other 43 clinics) and its performance on others. When correlations between pairs of up-to-date rates within clinics were examined, only 4 of 28 service pairs were positive and statistically significant and only 1 had a correlation coefficient that exceeded 0.5 (for mammography and clinical breast examination). CONCLUSION: There is wide variation in the rates at which various preventive services are performed, both between and within clinics. This variation, which is probably due to a lack of organized prevention systems that cover multiple services, provides a clear target for improvement efforts.

A CQI intervention to change the care of depression: a controlled study.

CONTEXT: Although new strategies for managing depression in primary care (e.g., nurse telephone calls, collaborative care) have been shown to be effective, no models are available for their systematic implementation in the "real world." OBJECTIVE: To test whether a continuous quality improvement (CQI) intervention could be used to implement systems in primary care clinics to improve the care and outcomes for patients diagnosed with depression. DESIGN: Before-after study with concurrent controls. INTERVENTION: A multidisciplinary team from the three intervention clinics developed and implemented a graded set of five care management options, ranging from watchful waiting (nurse telephone call in 4 to 6 weeks) to mental health management, which clinicians could order for their patients with depression. SETTING: 9 primary care clinics in greater Minneapolis-St. Paul, Minnesota. PATIENTS: Outpatients 18 years of age and older whose primary care clinic visit included an International Classification of Diseases, 9th revision, code for depression and who completed baseline and 3-month follow-up surveys before and after the intervention. MAIN OUTCOME MEASURES: Measures of process of care (follow-up depression visits to physician, mental health visits, follow-up telephone calls) and outcomes of care (improved depression symptoms over 3 months, satisfaction with care). RESULTS: Although the CQI team appeared to function well, only 30 of the 257 patients identified from depression-coded visits for this study were referred to the new system during the 3-month evaluation period. In both the intervention and control clinics, follow-up visits, mental health referrals, and follow-up telephone calls did not improve significantly from the preintervention levels of about 0.5 for a primary care visit, 0.4 for a mental health visit, or 0.1 for a follow-up phone call per person. The same was true of patient outcomes: The proportion of patients in the intervention and control clinics who had improved depression symptoms and those who were very satisfied with their depression care did not change significantly from the preintervention levels of 43% and 26%, respectively. CONCLUSIONS: Our attempt to improve the primary care management of depression failed because physicians used the new order system so infrequently. Whether a greater leadership commitment to change or a different improvement process would alter our findings is an open question.

Rural patients' interests in preventive medical care.

A number of national studies have reported patients' interests in preventive medical care, but rural populations have not been well studied. We surveyed patients from a major clinic in rural central Minnesota to determine their interests in preventive medical care and their physicians' perceptions of those interests. Of 270 patients who responded to a questionnaire, 63-93 percent agreed that physicians should perform a wide variety of primary and secondary preventive medical services, such as periodic health examinations and counseling about smoking, exercise, and diet. Study physicians recommended most preventive medical services at least as often as did their patients, but physicians consistently underestimated patients' wishes for these services. Our results indicate that this rural clinic population is interested in a broad range of preventive medical services, which was not fully appreciated by the physicians.

Dependency, social factors, and the smoking cessation process: the doctors helping smokers study.

We analyzed data obtained from a representative sample of the smoking patients (n = 1,338) of 66 family physicians to determine predictors of attempts to stop smoking, desire to quit smoking, and successful smoking cessation. Compared to subjects who made no attempt to quit smoking, subjects who tried to quit smoking tended to be younger, had tried to quit smoking in the year prior to the study, waited longer before smoking their first cigarette of the day, had more desire to quit smoking, and had more social support for quitting. Education and cigarettes smoked per day were not independently related to the subject making a quit attempt. Desire to quit smoking was associated with an attempt to quit in the year prior to the study and social support for smoking cessation (support of spouse, second most important social contact, and physician). Desire to quit smoking was not independently related to age, education, or dependency on cigarettes (measured by the number of cigarettes smoked per day and the length of time a subject waited before smoking the first cigarette of the day). Compared to subjects who tried to quit and failed, subjects who succeeded were older, smoked fewer cigarettes per day, and waited longer to smoke their first cigarette of the day. Spouse support, support of the second most important social contact, and advice of a doctor to quit smoking were not independently related to whether or not a cessation attempt would be successful. These data suggest that successful smoking cessation requires two components: social support to make an attempt to quit and the ability to overcome dependency on cigarettes to make the attempt successful.

Questionnaire instructions--does anybody read them?

In the absence of data useful to the design of instructions for self-administered questionnaires, a study was performed in a family practice clinic on people having their first complete physical there. Although 1,303 persons filled out a health questionnaire prior to their examination, only 36.5% gave evidence of having carefully read the brief instructions. Women did better than men and some occupational or educational subcategories were above this average, but no subgroup had a high enough response rate to warrant relying on the instructions for important information. In particular, there was no evidence that either those in poorer health or those completing a questionnaire for their young children were any more careful in reading the instructions. Those who design such self-administered questionnaires are advised to make the form completion self-evident, rather than to rely upon introductory instructions to convey this information.

Will patient satisfaction set the preventive services implementation agenda?

BACKGROUND: Patient satisfaction has become a measure of the quality of health care, and in highly competitive markets like the Twin Cities metropolitan area of Minnesota, it has become a health plan marketing tool. The purpose of this analysis is to examine whether the known association between preventive services and patient satisfaction might spontaneously lead clinicians to recommend preventive services at greater rates. DESIGN: We conducted a mail survey of a stratified random sample (n = 6,830) of adult patients who had recently visited a physician in one of 44 clinics in and around Minneapolis-St. Paul, Minnesota. The main outcome measures are patient-reported rates of being advised to have eight preventive services, patient satisfaction with preventive services, patient satisfaction with overall health care, and correlations among these variables. RESULTS: Self-reports of being advised to have a preventive service when due were correlated with higher levels of satisfaction with that specific service only at levels of r = 0.16 to r = 0.35. They were correlated at levels of r = 0.01 to r = 0.27 with the Group Health Association of America satisfaction index. CONCLUSIONS: Although there is a positive association between being advised to have a preventive service on the one hand and reporting satisfaction with care on the other, this association appears too weak to spontaneously stimulate physicians to recommend preventive services to their patients. This suggests that, if preventive services are to be delivered at higher rates, they must become an explicit component of quality evaluations.
