To compare the effects of computerized and paper-based versions of guidelines on recently qualified physicians' consultation practices.
                Two arm cluster randomized controlled trial. Physicians were randomized to receive computerized or textbook-based versions of the same guidelines for a 4-week study period. Physicians' compliance with guideline recommendations about laboratory, radiological, physical and other examinations, procedures, nonpharmacologic and pharmacologic treatments, physiotherapy, and referrals were measured by case note review.
                There were 139 recently qualified physicians working in 96 primary healthcare centers in Finland who participated in the study. Data on 4,633 patient encounters were abstracted, of which 3,484 were suitable for further analysis. Physicians' compliance with guidelines was high (over 80% for use of laboratory, radiology, physical examinations, and referrals). There were no significant differences in physicians' consultation practices in any of the measured outcomes between the computerized and textbook group.
                Guidelines are a useful source of information for recently qualified physicians working in primary care. However, the method of presentation of the guidelines (electronic or paper) does not have an effect on guideline use or their impact on decisions. Other factors should be considered when choosing the method of presentation of guidelines, such as information-seeking time, ease of use during the consultation, ability to update, production costs, and the physician's own preferences. To determine whether a new model of primary care, Chronic Care Clinics, can improve outcomes of common geriatric syndromes (urinary incontinence, falls, depressive symptoms, high risk medications, functional impairment) in frail older adults.
                Randomized controlled trial with 24 months of follow-up. Physician practices were randomized either to the Chronic Care Clinics intervention or to usual care.
                Nine primary care physician practices that comprise an ambulatory clinic in a large staff-model HMO in western Washington State.
                Those patients aged 65 and older in each practice with the highest risk for being hospitalized or experiencing functional decline.
                Intervention practices (5 physicians, 96 patients) held half-day Chronic Care Clinics every 3 to 4 months. These clinics included an extended visit with the physician and nurse dedicated to planning chronic disease management; a pharmacist visit that emphasized reduction of polypharmacy and high-risk medications; and a patient self-management/support group. Control practices (4 physicians, 73 patients) received usual care.
                Changes in self-reported urinary incontinence, frequency of falls, depressive symptoms, physical function, and satisfaction were analyzed using an intention-to-treat analysis adjusted for baseline differences, covariates, and practice-level variation. Prescriptions for high-risk medications and cost/utilization data obtained from administrative data were similarly analyzed.
                After 24 months, no significant improvements in frequency of incontinence, proportion with falls, depression scores, physical function scores, or prescriptions for high risk medications were demonstrated. Costs of medical care including frequency of hospitalization, hospital days, emergency and ambulatory visits, and total costs of care were not significantly different between intervention and control groups. A higher proportion of intervention patients rated the overall quality of their medical care as excellent compared with control patients (40.0% vs 25.3%, P = .10).
                Although intervention patients expressed high levels of satisfaction with Chronic Care Clinics, improved outcomes for selected geriatric syndromes were not demonstrated. These findings suggest the need for developing greater system-wide support for managing geriatric syndromes in primary care and illustrate the challenges of conducting practice improvement research in a rapidly changing delivery system. Translation of evidence-based guidelines into clinical practice has been inconsistent. We performed a randomized, controlled trial of guideline-based care suggestions delivered to physicians when writing orders on computer workstations.
                Inner-city academic general internal medicine practice.
                Randomized, controlled trial of 246 physicians (25 percent faculty general internists, 75 percent internal medicine residents) and 20 outpatient pharmacists. We enrolled 706 of their primary care patients with asthma or chronic obstructive pulmonary disease. Care suggestions concerning drugs and monitoring were delivered to a random half of the physicians and pharmacists when writing orders or filling prescriptions using computer workstations. A 2 x 2 factorial randomization of practice sessions and pharmacists resulted in four groups of patients: physician intervention, pharmacist intervention, both interventions, and controls. DATA EXTRACTION/COLLECTION METHODS: Adherence to the guidelines and clinical activity was assessed using patients' electronic medical records. Health-related quality of life, medication adherence, and satisfaction with care were assessed using telephone questionnaires.
                During their year in the study, patients made an average of five scheduled primary care visits. There were no differences between groups in adherence to the care suggestions, generic or condition-specific quality of life, satisfaction with physicians or pharmacists, medication compliance, emergency department visits, or hospitalizations. Physicians receiving the intervention had significantly higher total health care costs. Physician attitudes toward guidelines were mixed.
                Care suggestions shown to physicians and pharmacists on computer workstations had no effect on the delivery or outcomes of care for patients with reactive airways disease. Numbers of diagnostic tests ordered by primary care physicians are growing and many of these tests seem to be unnecessary according to established, evidence-based guidelines. An innovative strategy that focused on clinical problems and associated tests was developed.
                To determine the effects of a multifaceted strategy aimed at improving the performance of primary care physicians' test ordering.
                Multicenter, randomized controlled trial with a balanced, incomplete block design and randomization at group level. Thirteen groups of primary care physicians underwent the strategy for 3 clinical problems (arm A; cardiovascular topics, upper and lower abdominal complaints), while 13 other groups underwent the strategy for 3 other clinical problems (arm B; chronic obstructive pulmonary disease and asthma, general complaints, degenerative joint complaints). Each arm acted as a control for the other.
                Primary care physician groups in 5 regions in the Netherlands with diagnostic centers recruited from May to September 1998.
                Twenty-six primary care physician groups, including 174 primary care physicians.
                During the 6 months of intervention, physicians discussed 3 consecutive, personal feedback reports in 3 small group meetings, related them to 3 evidence-based clinical guidelines, and made plans for change.
                According to existing national, evidence-based guidelines, a decrease in the total numbers of tests ordered per clinical problem, and of some defined inappropriate tests, is considered a quality improvement.
                For clinical problems allocated to arm A, the mean total number of requested tests per 6 months per physician was reduced from baseline to follow-up by 12% among physicians in the arm A intervention, but was unchanged in the arm B control, with a mean reduction of 67 more tests per physician per 6 months in arm A than in arm B (P =.01). For clinical problems allocated to arm B, the mean total number of requested tests per 6 months per physician was reduced from baseline to follow-up by 8% among physicians in the arm B intervention, and by 3% in the arm A control, with a mean reduction of 28 more tests per physician per 6 months in arm B than in arm A (P =.22). Physicians in arm A had a significant reduction in mean total number of inappropriate tests ordered for problems allocated to arm A, whereas the reduction in inappropriate test ordered physicians in arm B for problems allocated to arm B was not statistically significant.
                In this study, a practice-based, multifaceted strategy using guidelines, feedback, and social interaction resulted in modest improvements in test ordering by primary care physicians. Little is known about the use of palliative care for outpatients who continue to pursue treatment of their underlying disease or whether outpatient palliative medicine consultation teams improve clinical outcomes.
                We conducted a year-long controlled trial involving 50 intervention patients and 40 control patients in a general medicine outpatient clinic. Primary care physicians referred patients with advanced congestive heart failure, chronic obstructive pulmonary disease, or cancer who had a prognosis ranging from 1 to 5 years. In the intervention group, the primary care physicians received multiple palliative care team consultations, and patients received advance care planning, psychosocial support, and family caregiver training. Clinical and health care utilization outcomes were assessed at 6 and 12 months.
                Groups were similar at baseline. Similar numbers of patients died during the study year (P =.63). After the intervention, intervention group patients had less dyspnea (P =.01) and anxiety (P =.05) and improved sleep quality (P =.05) and spiritual well-being (P =.007), but no change in pain (P =.41), depression (P =.28), quality of life (P =.43), or satisfaction with care (P =.26). Few patients received recommended analgesic or antidepressant medications. Intervention patients had decreased primary care (P =.03) and urgent care visits (P =.04) without an increase in emergency department visits, specialty clinic visits, hospitalizations, or number of days in the hospital. There were no differences in charges (P =.80).
                Consultation by a palliative medicine team led to improved patient outcomes in dyspnea, anxiety, and spiritual well-being, but failed to improve pain or depression. Palliative care for seriously ill outpatients can be effective, but barriers to implementation must be explored. To determine the effectiveness of Internet-based audit and feedback to physicians to improve care for diabetes and hypertension.
                Time-series analysis of an intervention.
                The study setting was Harvard Vanguard Medical Associates, a 14-site multispecialty group in greater Boston. The study period was July 1997-June 1999.
                were 12 primary care internal medicine residents who provided care to adult patients with diabetes (n = 76 pre-intervention and n = 88 post-intervention), hypertension (n = 329 pre-intervention and n = 338 post-intervention), or both (n = 62 pre-intervention and n = 71 post-intervention). We determined the proportion of each resident's patients whose care fulfilled national guidelines for quality (i.e. diabetes patients had hemoglobin testing in the previous 6 months or hypertension patients received a beta-blocker or diuretic in the same time period). After meeting individually with each resident to obtain informed consent and to encourage participation, we sent each resident information for accessing his or her practice profile on a secure website. The main outcome measures were (i) the proportion of resident physicians who accessed their profiles and (ii) change following the intervention in the proportion of patients whose care followed national guidelines.
                Over a 1-year period, only four of the 12 residents accessed their websites. One of the residents visited her site three times, while the other three residents visited their sites once each. In interrupted time-series analyses, the intervention had no discernible effect on adherence to practice guidelines for diabetes or hypertension.
                The lack of participation in this Internet-based intervention may have important implications for the development of future programs that require physicians to interact with technology to improve quality of care. Primary care physicians are increasingly being asked to participate in postal surveys. Difficulties in achieving adequate response rates among physicians have been reported. We investigated the effect of two low-cost interventions on response to a primary care physician postal questionnaire.
                A 2x2 factorial trial was developed within the context of a national survey assessing views and practices of physicians regarding prostate-specific antigen testing. We evaluated questionnaire order (version 1: demographics first, version 2: topic-specific questions first) and written precontact. A national database of primary care physicians was compiled. One thousand five hundred ninety-nine physicians were randomly selected, stratified by health board, and randomized.
                47.9% of eligible physicians completed a questionnaire. There was a statistically significant 5.1% higher response rate among physicians receiving version 1 of the questionnaire than those receiving version 2 (50.6% vs. 45.4%, P=0.05); the adjusted odds of response were significantly raised (odds ratio=1.24; 95% confidence interval=1.01-1.54). Precontact resulted in a nonsignificant 3.6% increase in response (49.8% vs. 46.2%; P=0.16). The interventions did not interact.
                Ordering questionnaires with general questions first can significantly increase response rates, whereas precontact can achieve a modest increase. These strategies may enhance response while adding little to the cost of a physician survey. The long-term management of patients with chronic conditions such as hypertension presents problems for the health services. Shared care addresses these by coordinating care and defining responsibilities.
                This study set out to investigate the feasibility, acceptability and cost effectiveness of shared general practitioner-hospital care for well-controlled hypertensive patients in an urban area by comparing three matched groups of patients.
                A total of 554 outpatient clinic attenders, considered suitable for shared care by their consultant, were randomly allocated to shared care or follow up in the outpatient clinic; a third group of 277 patients was selected from a nurse practitioner clinic. Main outcome measures were the proportion of patients in the second year of follow up who had undergone a complete review (blood pressure measurement, serum creatinine level result and electrocardiograph report), acceptability to patients and general practitioners as assessed by questionnaire, and cost per complete review in year two (National Health Service and patient costs).
                After two years 220 (82%) shared care patients had had a complete review compared with 146 (54%) outpatient clinic attenders and 202 (75%) nurse practitioner clinic attenders. Blood pressure control was similar in each group. Of 297 general practitioners invited, 85% wished to participate in the study; 61% of questionnaire respondents subsequently wanted shared care to continue while 25% were unsure. Half of the patients receiving shared care preferred this method of follow up. The rank order of cost-effectiveness ratios was shared care, nurse practitioner care and conventional outpatient care, relative differences being most marked when only patient costs were considered.
                Shared care for hypertension is feasible in an urban setting, acceptable to the majority of participants and is a cost-effective method of long-term follow up. To evaluate and compare the effects of two types of continuing medical education (CME) programs on the communication skills of practicing primary care physicians.
                Fifty-three community-based general internists and family practitioners practicing in the Portland, Oregon, metropolitan area and 473 of their patients.
                For the short program (a 4 1/2-hour workshop), 31 physicians were randomized to either the intervention or the control group. In the long program (a 2 1/2-day course), 20 physicians participated with no randomization. A research assistant visited all physicians' offices both one month before and one month after the CME program and audiotaped five sequential visits each time. Data were based on analysis of the content and the affect of the interviews, using the Roter Interactional Analysis Scheme.
                Based on both t-test analysis and analysis of covariance, no effect on communication was evident from the short program. The physicians enrolled in the long program asked more open-ended questions, more frequently asked patients' opinions, and gave more biomedical information than did the physicians in the short program. Patients of the physicians who attended the long program tended to disclose more biomedical and psychosocial information to their physicians. In addition, there was a decrease in negative affect for both patient and physician, and patients tended to demonstrate fewer signs of outward distress during the visit.
                This study demonstrates some potentially important changes in physicians' and patients' communication after a 2 1/2-day CME program. The changes demonstrated in both content and affect may have important influences on both biologic outcome and physician and patient satisfaction.
The findings of this review do not provide sufficient evidence to support or resist a policy of altering the lengths of primary care physicians' consultations. Further trials are needed that focus on health outcomes and cost effectiveness.
