The effect of a disease management intervention on quality and outcomes of dementia care: a randomized, controlled trial.

BACKGROUND: Adherence to dementia guidelines is poor despite evidence that some guideline recommendations can improve symptoms and delay institutionalization of patients. OBJECTIVE: To test the effectiveness of a dementia guideline-based disease management program on quality of care and outcomes for patients with dementia. DESIGN: Clinic-level, cluster randomized, controlled trial. SETTING: 3 health care organizations collaborating with 3 community agencies in southern California. PARTICIPANTS: 18 primary care clinics and 408 patients with dementia age 65 years or older paired with 408 informal caregivers. INTERVENTION: Disease management program led by care managers and provided to 238 patient-caregiver pairs at 9 intervention clinics for more than 12 months. MEASUREMENTS: Adherence to 23 guideline recommendations (primary outcome) and receipt of community resources and patient and caregiver health and quality-of-care measures (secondary outcomes). RESULTS: The mean percentage of per-patient guideline recommendations to which care was adherent was significantly higher in the intervention group than in the usual care group (63.9% vs. 32.9%, respectively; adjusted difference, 30.1% [95% CI, 25.2% to 34.9%]; P < 0.001). Participants who received the intervention had higher care quality on 21 of 23 guidelines (P < or = 0.013 for all), and higher proportions received community agency assistance (P < or = 0.03) than those who received usual care. Patient health-related quality of life, overall quality of patient care, caregiving quality, social support, and level of unmet caregiving assistance needs were better for participants in the intervention group than for those in the usual care group (P < 0.05 for all). Caregiver health-related quality of life did not differ between the 2 groups. LIMITATIONS: Participants were well-educated, were predominantly white, had a usual source of care, and were not institutionalized. Generalizability to other patients and geographic regions is unknown. Also, costs of a care management program under fee-for-service reimbursement may impede adoption. CONCLUSIONS: A dementia guideline-based disease management program led to substantial improvements in quality of care for patients with dementia. Current Controlled Trials identifier: ISRCTN72577751.

Assessing the institutional approach to implementing smoking cessation practice guidelines in veterans health administration facilities.

National smoking cessation guidelines include recommended strategies for providers and health care organizations, but they offer little guidance on how to structure care. We conducted a cross-sectional survey at 40 Veterans Health Administration facilities, to describe the structure of smoking cessation care, to assess adherence to national guidelines, and to assess facilities' preferred approach to providing smoking cessation treatment. We categorized sites as those using a primary care approach (most smokers treated by the primary care provider) versus a specialty approach (medication restricted to smoking cessation clinics, to which most patients were referred). Nearly all sites reported systematic screening for smoking and counseling of smokers, usually by both nursing staff members and the primary care provider. Most sites used a specialty approach, restricting medication access to smokers attending a cessation program. Future research should evaluate whether this approach provides adequate access and responsiveness to patient preferences for the full population of smokers in primary care.

Creating the evidence base for quality improvement collaboratives.

Intensive efforts are under way to improve health care quality and safety throughout the United States and abroad. Many of these efforts use the quality improvement collaborative method, an approach emphasizing collaborative learning and exchange of insights and support among a set of health care organizations. Unfortunately, the widespread acceptance and reliance on this approach are based not on solid evidence but on shared beliefs and anecdotal affirmations that may overstate the actual effectiveness of the method. More effective use of the collaborative method will require a commitment by users, researchers, and other stakeholders to rigorous, objective evaluation and the creation of a valid, useful knowledge and evidence base. Development of this evidence base will require improved conceptions of the nature of quality problems, quality improvement processes, and the types of research needed to elucidate these processes. Researchers, journal editors, and funding agencies must also cooperate to ensure that published evaluations are relevant, comprehensive, and cumulative.

Case finding for population-based studies of rheumatoid arthritis: comparison of patient self-reported ACR criteria-based algorithms to physician-implicit review for diagnosis of rheumatoid arthritis.

OBJECTIVE: To evaluate the interrater reliability of rheumatologist diagnosis of rheumatoid arthritis (RA) and the concordance between rheumatologist and computer algorithms for assessing the accuracy of a diagnosis of RA. METHODS: Self-reported data regarding symptoms and signs for a diagnosis of RA were considered by a panel of rheumatologists and by computer algorithms to assess the probability of a diagnosis of RA for 90 patients. The rheumatologists' review was validated through medical record. RESULTS: The interrater reliability among rheumatologists regarding a diagnosis of RA was 84%; the chance-corrected agreement (kappa) was 0.66. Agreement between the rheumatologists' rating and the best-performing algorithm was 95%. Using rheumatologist's review as a standard, the sensitivity of the algorithm was 100%, specificity was 88%, and the positive predictive value was 91%. The validation of rheumatologist's review by medical record showed 81% sensitivity, 60% specificity, and 78% positive predictive value. CONCLUSION: Reliability of rheumatologists' assignment of a diagnosis of RA by using self-report data is good. Algorithms defining symptoms as either joint swelling or tenderness with symptom duration >or=4 weeks have a better agreement with rheumatologist's diagnosis than do ones relying on a longer symptom duration. RELEVANCE: These findings have important implications for health services research and quality improvement interventions pertinent to case finding for RA through self-report data.

Development and evaluation of a patient self-report case-finding method for rheumatoid arthritis.

OBJECTIVE: To describe the development and evaluation of a patient self-report case-finding method for rheumatoid arthritis (RA) not dependent on direct contact with the treating physicians. METHODS: The American College of Rheumatology criteria for RA diagnosis were adapted for patient self-report using a questionnaire, and alternative scoring algorithms were evaluated to balance case-finding sensitivity and specificity. Positive rheumatoid factor tests were used to identify 1053 individuals in 2 large healthcare organizations; 440 agreed to receive study materials. Case-finding results were validated by medical record review (MRR) for a random sample of 90 patients. Three scoring algorithms were compared with MRR for likelihood of RA diagnosis. Cases not classifiable by algorithm were flagged and reviewed by 2 expert physicians for likelihood of RA diagnosis. RESULTS: Pilot testing demonstrated that patients comprehended the questionnaire and were willing to answer the questions. Completed questionnaires were returned by 265 (60%) of the 440 patients contacted. Following expert physician review of 16 flagged cases in the 90-patient MRR subsample, the most accurate scoring algorithm demonstrated 80% sensitivity, 67% specificity, 74% accuracy, and 77% positive predictive value for detecting early RA. CONCLUSION: The case-finding method represents a promising tool for identifying RA patients, with potential application in research and quality-assurance activities. RELEVANCE: This case-finding method should be useful in research and quality-assurance efforts requiring identification of RA patients treated by all types of providers in healthcare organizations in which centralized laboratory data are available.

Physician awareness and self-reported use of local and national guidelines for community-acquired pneumonia.

OBJECTIVES: To assess physician awareness and reported use of medical guidelines for community-acquired pneumonia (CAP), and to identify factors associated with variations in awareness and use of these guidelines. DESIGN: A questionnaire was administered during the preintervention phase of a randomized clinical trial of a pneumonia guideline implementation strategy. PARTICIPANTS: Three hundred and fifty-two physicians who managed CAP patients at 7 Pittsburgh, PA hospitals completed the questionnaire. Physician and practice setting characteristics, and physician awareness and reported use of national American Thoracic Society (ATS) and local (hospital-developed) guidelines for CAP were assessed. RESULTS: Overall, 48% reported being influenced by ATS guidelines and 20% reported using these guidelines; 48% were uncertain whether a local pneumonia guideline existed. Only 28% of physicians who knew a local guideline existed reported frequently using the guideline. Use of national ATS guidelines was independently associated with practice as an infectious disease or pulmonary medicine specialist, nonpatient care-related professional activities, and intellect personality score. Use of local guidelines was independently negatively associated with practice as an infectious disease or pulmonary medicine specialist, and positively associated with positive attitudes toward practice guidelines. CONCLUSIONS: Results indicate low levels of awareness and use of guidelines for the management of CAP. Key indicators (e.g., medical specialty, fewer clinical duties, and positive attitudes about guidelines) were associated with greater use of national and local guidelines. If replicated with data on actual physician management practices, more effective guideline implementation strategies will be necessary to encourage compliance with practice guidelines for the management of CAP.

Quality improvement implementation in the nursing home.

OBJECTIVE: To examine quality improvement (QI) implementation in nursing homes, its association with organizational culture, and its effects on pressure ulcer care. DATA SOURCES/STUDY SETTING: Primary data were collected from staff at 35 nursing homes maintained by the Department of Veterans Affairs (VA) on measures related to QI implementation and organizational culture. These data were combined with information obtained from abstractions of medical records and analyses of an existing database. STUDY DESIGN: A cross-sectional analysis of the association among the different measures was performed. DATA COLLECTION/EXTRACTION METHODS: Completed surveys containing information on QI implementation, organizational culture, employee satisfaction, and perceived adoption of guidelines were obtained from 1,065 nursing home staff. Adherence to best practices related to pressure ulcer prevention was abstracted from medical records. Risk-adjusted rates of pressure ulcer development were calculated from an administrative database. PRINCIPAL FINDINGS: Nursing homes differed significantly (p<.001) in their extent of QI implementation with scores on this 1 to 5 scale ranging from 2.98 to 4.08. Quality improvement implementation was greater in those nursing homes with an organizational culture that emphasizes innovation and teamwork. Employees of nursing homes with a greater degree of QI implementation were more satisfied with their jobs (a 1-point increase in QI score was associated with a 0.83 increase on the 5-point satisfaction scale, p<.001) and were more likely to report adoption of pressure ulcer clinical guidelines (a 1-point increase in QI score was associated with a 28 percent increase in number of staff reporting adoption, p<.001). No significant association was found, though, between QI implementation and either adherence to guideline recommendations as abstracted from records or the rate of pressure ulcer development. CONCLUSIONS: Quality improvement implementation is most likely to be successful in those VA nursing homes with an underlying culture that promotes innovation. While QI implementation may result in staff who are more satisfied with their jobs and who believe they are providing better care, associations with improved care are uncertain.

Interventions that increase use of adult immunization and cancer screening services: a meta-analysis.

PURPOSE: The relative effectiveness of the diverse approaches used to promote preventive care activities, such as cancer screening and adult immunization, is unknown. Despite many high-quality published studies, practices and policymakers attempting to improve preventive care have little definitive information on which to base decisions. Thus, we quantitatively assessed the relative effectiveness of previously studied approaches for improving adherence to adult immunization and cancer screening guidelines. DATA SOURCES: MEDLINE, the Cochrane Effective Practice and Organization of Care Review Group register, previous systematic reviews, and the Medicare Health Care Quality Improvement Project database. STUDY SELECTION: Controlled clinical trials that assessed interventions to increase use of immunizations for influenza and pneumococcal pneumonia and screening for colon, breast, and cervical cancer in adults. DATA EXTRACTION: Two reviewers independently extracted data on characteristics and outcomes from unmasked articles. Intervention components to increase use of services were classified as reminder, feedback, education, financial incentive, legislative action, organizational change, or mass media campaign. DATA SYNTHESIS: Of 552 abstracts and articles, 108 met the inclusion criteria. To assess the effect of intervention components, meta-regression models were developed for immunizations and each cancer screening service by using 81 studies with a usual care or control group. The most potent intervention types involved organizational change (the adjusted odds ratios for increased use of services from organizational change ranged from 2.47 to 17.6). Organizational change interventions included the use of separate clinics devoted to prevention, use of a planned care visit for prevention, or designation of nonphysician staff to do specific prevention activities. The next most effective intervention components were patient financial incentives (adjusted odds ratios, 1.82 to 3.42) and patient reminders (adjusted odds ratios, 1.74 to 2.75); the adjusted odds ratios ranged from 1.29 to 1.53 for patient education and from 1.10 to 1.76 for feedback. CONCLUSIONS: Rates of adult immunization and cancer screening are most likely to improve when a health care organization supports performance of these activities through organizational changes in staffing and clinical procedures. Involving patients in self-management through patient financial incentives and reminders is also likely to positively affect performance.

Consensus statement for the management of chronic pelvic pain and endometriosis: proceedings of an expert-panel consensus process.

OBJECTIVE: To develop recommendations for the medical and surgical care of women who present with chronic pelvic pain (CPP) and are likely to have endometriosis as the underlying cause. DESIGN: An expert panel comprised of practicing gynecologists from throughout the United States and experts in consensus guideline development was convened. After completion of a structured literature search and creation of draft algorithms by an executive committee, the expert panel of >50 practicing gynecologists met for a 2-day consensus conference during which the clinical recommendations and algorithms were reviewed, refined, and then ratified by unanimous or near-unanimous votes. PATIENT(S): Women presenting with CPP who are likely to have endometriosis as the underlying cause. MAIN OUTCOME MEASURE(S): None. CONCLUSION(S): Chronic pelvic pain frequently occurs secondary to nongynecologic conditions that must be considered in the evaluation of affected women. For women in whom endometriosis is the suspected cause of the pain, laparoscopic confirmation of the diagnosis is unnecessary, and a trial of medical therapy, including second-line therapies such as danazol, GnRH agonists, and progestins, is justified provided that there are no other indications for surgery such as the presence of a suspicious adnexal mass. When surgery is necessary, laparoscopic approaches seem to offer comparable clinical outcomes to those performed via laparotomy, but with reduced morbidity. The balance of evidence supports the use of adjuvant postoperative medical therapy after conservative surgery for CPP. There is some evidence that adjuvant presacral neurectomy adds benefit for midline pain, but currently, there is inadequate evidence to support the use of uterosacral nerve ablation or uterine suspension. Hysterectomy alone has undocumented value in the surgical management of women with endometriosis-associated CPP.

Physicians' preferences for specialty involvement in the care of patients with neurological conditions.

BACKGROUND: Recent changes in the US health care system have produced questions about the appropriate roles and responsibilities of generalist and specialist physicians within a primary care-centered health care delivery system. OBJECTIVES: To determine neurologists' and primary care physicians' preferences for specialist involvement in the management of common neurologic conditions and the factors influencing these preferences. RESEARCH DESIGN AND SUBJECTS: A self-administered questionnaire was developed with the assistance of a multispecialty Advisory Board and sent to a stratified probability sample of 608 family physicians, 624 general internists, and 492 neurologists. MEASURES: The questionnaire contained three clinical scenarios, each followed by questions regarding respondent preferences for the primary care physician to manage alone, curbside, or refer to a specialist. The questionnaire also contained knowledge questions corresponding to each scenario and physician and practice characteristics questions. RESULTS: Response rate was 60%. For all three scenarios, primary care physicians' preferences to involve a specialist differed substantially from neurologists' preferences, with nearly all neurologists preferring involvement of a specialist. Primary care physicians with less knowledge were more likely to prefer assistance from a neurologist. Physician age and practice setting influenced the type of assistance preferred (curbside vs. referral). Utilization management techniques and financial incentives had little influence on physician preferences to involve a specialist. CONCLUSIONS: The extensive disagreement between primary care physicians' and specialists' preferences for specialty involvement represents cause for considerable concern, supporting further efforts to identify where inappropriate referral processes are occurring and to implement mechanisms for improving the coordination and quality of primary and specialty care.

Assessing the structure of smoking cessation care in the Veterans Health Administration.

PURPOSE: National smoking cessation practice guidelines offer recommendations regarding the processes and structure of care. Facilities routinely measure the processes of care but not the structure of care. This pilot study assessed the structure of smoking cessation care at Veterans Health Administration facilities. METHODS: Key informants at 18 sites completed a brief checklist survey adapted from national smoking cessation guidelines. Responses were compared with detailed site surveys. RESULTS: Guideline adherence was seen in identifying smokers and treating inpatient smokers. Areas of low adherence include offering incentives and defining staff responsibilities. The checklist survey showed poor correspondence with the detailed survey, with low agreement on systematic screening (kappa = .21) and higher agreement on primary care prescribing authority (kappa = .53). DISCUSSION: This pilot survey provides a potential rapid method for assessing adherence to systems recommendations from the national smoking cessation guidelines. The relatively low agreement with a more detailed survey suggests that the two surveys may have been measuring different aspects of smoking cessation care.
