Continuity of primary care: to whom does it matter and when?
BACKGROUND: Inconsistent findings on the value of continuity of care can stem from variability in its importance to different subsets of patients. We therefore examined the association among patient and visit characteristics and extent to which the patient valued continuity of care (PVC). We hypothesized that continuity would be more important to patients who are older, sicker, and female, who have established a relationship with their physician, and whose visit addresses more complex problems. METHODS: A study of 4,454 consecutive outpatient visits to 138 community-based family physicians used a 3-item measure (alpha = 0.67) of PVC. The patient's report of (1) the adequacy of primary care for the visit and (2) satisfaction with the physician on that visit was assessed with multiple measures. Analyses examined the associations among PVC and patient-reported satisfaction with the physician and adequacy of the visit. RESULTS: Extremes of age, female sex, less education, Medicare and Medicaid insurance, number of chronic conditions and medications, number of visits to the practice, and worse self-reported health status were associated with higher value placed on continuity (P < .001 for all except sex, where P = .015). Patients who value continuity and did not see a regular physician rated adequacy of the visit lower (for 7 attributes of the visit) than those seeing their own physician. Satisfaction with the physician for the visit was greatest among patients who value continuity and saw their regular physician. CONCLUSIONS: Continuity of physician care is associated with more positive assessments of the visit and appears to be particularly important for more vulnerable patients. Health care systems and primary care practices should devote additional effort to maintaining a continuity relationship with these vulnerable patients.

Patient-physician shared experiences and value patients place on continuity of care.
PURPOSE: We undertook a study to examine the impact of experiences shared between patient and physician and the value patients place on continuity of care. METHODS: Data on 4,454 patients collected in The Direct Observation of Primary Care (DOPC) study conducted between October 1994 and August 1995 were analyzed to assess the value patients place on continuity, length of patient-physician relationship, and experiences shared between patient and physician. RESULTS: A significant interaction was yielded between duration of relationship and experiences shared between patient and physician (P = .03). For all lengths of relationship with the physician, the value that patients have for continuity increased when patients indicated experiences shared with the physician. For patients who did not report experiences shared with the physician, the longer the relationship, the greater the value placed on continuity. CONCLUSIONS: The results of this study point to the importance of the experiences shared between patients and physicians and the value that patients place on continuity with their regular physician.

How many problems do family physicians manage at each encounter? A WReN study.
PURPOSE: The number of problems managed concurrently by family physicians during patient encounters has not been fully explored despite the implications for quality assessment, guideline implementation, education, research, administration, and funding. Our study objective was to determine the number of problems physicians report managing at each visit and compare that with the number reflected in the chart and the bill. METHODS: Twenty-nine members of the Wisconsin Research Network reported on encounters with 572 patients using a physician problem log. The patient chart notes and the diagnoses submitted for billing from the encounters were compared with the information in these logs. RESULTS: The physicians reported managing an average of 3.05 problems per encounter and recorded 2.82 in the chart and 1.97 on the bill. For all patients, 37% of encounters addressed more than 3 problems, and 18% addressed more than 4. For patients older than 65 years, there was an average of 3.88 problems at each visit, and for diabetic patients there was an average of 4.60. There was evidence for the selective omission of mental health and substance problems from the diagnoses used for billing. CONCLUSIONS: Family medicine involves the concurrent care of multiple problems, which billing data do not adequately reflect. Our findings suggest a mismatch between family medicine and current approaches to quality assessment, guideline implementation, education, research, administration, and funding. Activities in all these areas need to address the physician's task of prioritizing and integrating care for multiple problems concurrently.

Physician-elder interaction in community family practice.
OBJECTIVE: To determine whether outpatient visits by elders seeing community family physicians differ in length or content from visits by younger patients; socioemotional preferences predict visit content; and satisfaction correlates with visit content differentially across age. METHODS: In a multimethod cross-sectional study of 84 community family practices in northeastern Ohio, 3453 adult patient visits with 138 community family physicians were observed; 2362 of these patients completed self-report questionnaires. Three age groups were compared: 18 to 64, 65 to 74, and over 74 years. Length and content of the physician-patient encounter was determined using the Davis Observation Code (DOC); satisfaction was assessed using the MOS 9-item Visit Rating Scale. RESULTS: Controlling for reason for visit and demographics, visit length averaged 10.7 minutes for each group. Visit content differed significantly on 13 of 20 DOC codes between one of the older groups and the younger group; in 4 instances, content varied between the 2 older groups. Although visit content varied as predicted by socioemotional theory, no consistent patterns of association between visit content and satisfaction emerged. DISCUSSION: Older patient visits differ from those of younger patients as might be predicted by socioemotional selectivity theory; however, there was little association of visit content with patient satisfaction.

Clinical judgment predicts culture results in upper respiratory tract infections.
BACKGROUND: We wanted to describe the natural history, familial transmission, microbiology, and accuracy of clinical judgment of potential pathogens of respiratory tract infections in a community family practice. METHODS: The study was a prospective case series in which consecutive patients requesting treatment for respiratory tract infections were evaluated after nurse triage during 3 fall-spring months in a solo family practice in suburban Cleveland, Ohio. According to the physician's usual practice, patients were classified into high-, medium-, and low-risk groups for bacterial illness based on their clinical signs and symptoms. Cultures were performed and sensitivities were determined for pathogens from the infected throat, nasopharynx, conjunctiva, or other sites. Patient symptoms and well-being were scored at the initial visit and at 3, 7 and 14 days later. RESULTS: There were 111 illness episodes in 86 patients; 94% had cultures taken, of which 38% grew a potentially pathogenic bacteria, most commonly group A streptococci, Branhamella catarrhalis or Staphylococcus aureus. The physician's judgment of bacterial infection was associated (P < .001) with having a positive culture (sensitivity 53%, specificity 78%, positive and negative predictive values 60% and 73%, respectively). A positive culture was associated with 2 of 16 signs or symptoms: purulent discharge from any site or a red swollen eye. There was no association of treatment status with clinical outcomes during 2 weeks of follow-up observation. CONCLUSION: Infection with a potentially pathogenic bacteria is difficult to determine solely by clinical signs and symptoms, but clinical judgment is associated with positive culture results. The effect of selective treatment of upper respiratory tract infection based on clinical signs and symptoms and patient and family culture results remains to be determined, but using clinical judgment could result in more selective antibiotic use than found in current practice patterns.

Understanding organizational designs of primary care practices.
During the past decade, many hospitals experienced difficulty integrating primary care practices into their health systems. We hypothesized that this difficulty may be, in part, a result of limited understanding of practice organizational designs. The structure and function of practices have not been well studied. In this article, we answer the following questions: Are practices all the same, or do variations in their organizational design exist? Do hospital designs predict the designs of affiliated practices? If variation exists, what are the management implications? Eighteen family practices, including nine affiliated with five separate hospital systems, were studied using an in-depth comparative case study design. A content analysis of the rich descriptive data from these cases indicates that a great variety exists in the organizational design of primary care practices, and this variety appears to be influenced by the initial conditions under which the practice was organized. Hospital system design in and of itself did not predict the design of affiliated practices. In fact, both affiliated and independent practices exhibited a range of design characteristics, some of which did not fit traditional models. Hospital systems that allowed greater flexibility of practice organizational designs were more effective at integrating and managing practices. Practices response to environmental change was greater when practice autonomy was highest. These findings suggest that a science of practice organizational design separate from that of hospitals is needed to help explain the success and failure of practices within health systems and to provide information for planning practice change.

Research guidelines for assessing the impact of healing relationships in clinical medicine.
This paper charts a course for assessing the impact of healing relationships in clinical medicine. The system of healing relationships is multidimensional, longitudinal, contextual, and emergent. In a new conceptual model, healing relationships are identified in terms of the conditions of healing intention, motivation, and information transfer, and in terms of the attributes of emotional engagement, mindfulness, and trust. Five components of quality in healing relationships--adaptability, cohesion, growth, caring-in-relation, and commitment--are noted, and the importance of timing, attunement, and cultural meaning systems are described. Communication, clinical method, caring, competence, and treatment characteristics are differentiated as mediating processes; expectancy and conditioning are positioned as antecedents of healing relationships. Multiple personal and contextual outcomes are addressed with a recommendation for assessing a minimal set of each, including symptom resolution, health status, sense of coherence, patient enablement, cost effectiveness, quality of care, efficiency, access, and healer satisfaction. A wheel of knowledge connects 3 ways of knowing--personal, connected, and objective--with appropriate methodology and research designs. Applying this wheel to the issue of assessing impact in healing relationships reveals the need for multiple methods, perspectives, and triangulations. A critical multiplist strategy is one means for advancing this area of research. A double-helix trial design is introduced, in which one strand consists of a standard quantitative approach and the other consists of qualitative methods. The 2 strands are bonded by the questions addressed and by the participants in the study.

A practice change model for quality improvement in primary care practice.
Faced with a rapidly changing healthcare environment, primary care practices often have to change how they practice medicine. Yet change is difficult, and the process by which practice improvement can be understood and facilitated has not been well elucidated. Therefore, we developed a model of practice change using data from a quality improvement intervention that was successful in creating a sustainable practice improvement. A multidisciplinary team evaluated data from the Study To Enhance Prevention by Understanding Practice (STEP-UP), a randomized clinical trial conducted to improve the delivery of evidence-based preventive services in 79 northeastern Ohio practices. The team conducted comparative case-study analyses of high- and low-improvement practices to identify variables that are critical to the change process and to create a conceptual model for the change. The model depicts the critical elements for understanding and guiding practice change and emphasizes the importance of these elements' evolving interrelationships. These elements are (1) motivation of key stakeholders to achieve the target for change; (2) instrumental, personal, and interactive resources for change; (3) motivators outside the practice, including the larger healthcare environment and community; and (4) opportunities for change--that is, how key stakeholders understand the change options. Change is influenced by the complex interaction of factors inside and outside the practice. Interventions that are based on understanding the four key elements and their interrelationships can yield sustainable quality improvements in primary care practice.
