Vitality, mental health, and satisfaction with information after breast cancer.

OBJECTIVE: The purpose of this study was to investigate the relationship between satisfaction with information about treatment-related and survivorship issues and mental health outcomes, including vitality, in long-term breast cancer survivors. METHODS: Participants who had finished treatment for breast cancer at least 3 months before enrollment completed a survey instrument designed to evaluate satisfaction with diagnostic and treatment information and satisfaction with survivorship information. Mental health and vitality were measured using the Medical Outcomes Study SF-36, and distress was measured using the impact of events scale. Bivariate analyses and linear regression analyses were performed to investigate the relationships between satisfaction with information, mental health, vitality, and distress controlling for clinical and treatment variables. RESULTS: The survey was completed by 231 participants (response rate 83%). More respondents were highly satisfied with treatment information (87%) than with survivorship information (30%, p=0.0001). There was a strong positive relationship between satisfaction with information (both treatment and survivorship issues) and vitality, mental health, and a strong negative relationship with distress. In multivariate analyses, satisfaction with treatment information was independently associated with mental health (p<0.01), and satisfaction with survivorship information was independently associated with vitality (p<0.05). CONCLUSION: Among patients who have completed treatment for breast cancer, satisfaction with diagnosis and treatment information is greater than satisfaction with survivorship issues and satisfaction with information may play an important role in mental health outcomes. PRACTICE IMPLICATIONS: Given the relationship between satisfaction with information and vitality, interventions to improve informational support regarding survivorship issues are warranted.

Influences on patients' ratings of physicians: Physicians demographics and personality.

OBJECTIVE: There is considerable interest in the influences on patients' ratings of physicians. METHODS: In this cross-sectional study, patients (n = 4616; age range: 18-65 years) rated their level of satisfaction with their primary care physicians (n = 96). Patients and physicians were recruited from primary care practices in the Rochester, NY metropolitan area. For analytic purposes, length of the patient-physician relationship was stratified (< or =1, 1-4, > or =5 years). Principal components factor analysis of items from the Health Care Climate Questionnaire, the Primary Care Assessment Survey and the Patient Satisfaction Questionnaire yielded a single factor labeled "Satisfaction" that served as the sole dependent variable. Higher scores mean greater satisfaction. Predictors of interest were patient demographics and morbidity as well as physician demographics and personality, assessed with items from the NEO-FFI. RESULTS: Patients treated by a physician for 1 year or less rated male physicians higher than female physicians. This gender difference disappeared after 1 year, but two physician personality traits, Openness and Conscientiousness, were associated with patients' ratings in lengthier patient-physician relationships. Patients report being more satisfied with physicians who are relatively high in Openness and average in Conscientiousness. Older patients provide higher ratings than younger patients, and those with greater medical burden rated their physicians higher. CONCLUSION: Patients' ratings of physicians are multidetermined. Future research on patient satisfaction and the doctor-patient relationship would benefit from a consideration of physician personality. Identifying physician personality traits that facilitate or undermine communication, trust, patient-centeredness, and patient adherence to prescribed treatments is an important priority. PRACTICE IMPLICATIONS: Learning environments could be created to reinforce certain traits and corresponding habits of mind that enhance patient satisfaction. Such a shift in the culture of medical education and practice could have implications for patient care.

Stability of decisional role preference over the course of cancer therapy.

Cancer patients vary in their preferred level of involvement in medical decision making, and responding to patients' desired level of involvement is a key element of good medical care. While the literature has clearly demonstrated heterogeneity among cancer patients' preferences, less is known about how the preferences of any given patient may change over time. This longitudinal study compared cancer patients' preferences for involvement in medical decision making from the time of diagnosis to the time of completion of therapy. Data from 729 cancer patients with mixed diagnoses were analyzed. Most patients reported a change in preferred level of involvement over time, and multivariate analysis demonstrated that patients tend to prefer a decreasing level of involvement over time (p<0.0001). Stability of patients' preferences was also associated with type of cancer, but not with other sociodemographic characteristics. The results from this study highlight the importance of reevaluating patients' preferences for involvement in medical decision making throughout the course of cancer therapy, as such preferences are likely to change.

Attitudes toward life-sustaining interventions among ambulatory black and white patients.

OBJECTIVES: The purpose of this study was to evaluate racial differences in preference for life-sustaining interventions in the context of various physical and mental health scenarios. DESIGN: Data were collected by using an investigator-administered survey. SETTING AND PATIENTS: Consecutive patients who self-identified as African American or Caucasian were recruited from two private primary care practices in Rochester, New York. MAIN OUTCOME MEASURES: Patients were asked to decide whether they would accept or decline life-sustaining intervention in eight scenarios, each involving a different combination of mental and physical disability. Information on religiousness, family integration, and experience with creating a healthcare proxy was also collected, as these variables were believed to be potential confounders of the relationship between race and preference. RESULTS: Data from 77 patients (50 Black patients and 27 White patients) were analyzed. In multivariate log linear modeling, race was a significant predictor of preference for life-sustaining therapy, even after controlling for degree of mental and physical disability. Religiousness, family integration, and experience with creating a healthcare proxy did not explain racial differences in preference for life-sustaining therapy. CONCLUSIONS: We have shown that ambulatory Black patients aged > or = 50 years are more likely than White patients to prefer life-sustaining care, and that these preferences persist across a wide range of mental and physical disabilities. This attitude conflicts with the prevailing ethic regarding end-of-life care, and Black patients and their families may consequently find have difficulty obtaining medical care that is consistent with their cultural values and beliefs. Policy decisions regarding end-of-life care must reflect a culturally diverse perspective.

Studying physician effects on patient outcomes: physician interactional style and performance on quality of care indicators.

Many prior studies which suggest a relationship between physician interactional style and patient outcomes may have been confounded by relying solely on patient reports, examining very few patients per physician, or not demonstrating evidence of a physician effect on the outcomes. We examined whether physician interactional style, measured both by patient report and objective encounter ratings, is related to performance on quality of care indicators. We also tested for the presence of physician effects on the performance indicators. Using data on 100 US primary care physician (PCP) claims data on 1,21,606 of their managed care patients, survey data on 4746 of their visiting patients, and audiotaped encounters of 2 standardized patients with each physician, we examined the relationships between claims-based quality of care indicators and both survey-derived patient perceptions of their physicians and objective ratings of interactional style in the audiotaped standardized patient encounters. Multi-level models examined whether physician effects (variance components) on care indicators were mediated by patient perceptions or objective ratings of interactional style. We found significant physician effects associated with glycohemoglobin and cholesterol testing. There was also a clinically significant association between better patient perceptions of their physicians and more glycohemoglobin testing. Multi-level analyses revealed, however, that the physician effect on glycohemoglobin testing was not mediated by patient perceived physician interaction style. In conclusion, similar to prior studies, we found evidence of an apparent relationship between patient perceptions of their physician and patient outcomes. However, the apparent relationships found in this study between patient perceptions of their physicians and patient care processes do not reflect physician style, but presumably reflect unmeasured patient confounding. Multi-level modeling may contribute to better understanding of the relationships between physician style and patient outcomes.

Measuring patient-centered communication in patient-physician consultations: theoretical and practical issues.

The goal of patient-centered communication (PCC) is to help practitioners provide care that is concordant with the patient's values, needs and preferences, and that allows patients to provide input and participate actively in decisions regarding their health and health care. PCC is widely endorsed as a central component of high-quality health care, but it is unclear what it is and how to measure it. PCC includes four communication domains: the patient's perspective, the psychosocial context, shared understanding, and sharing power and responsibility. Problems in measuring PCC include lack of theoretical and conceptual clarity, unexamined assumptions, lack of adequate control for patient characteristics and social contexts, modest correlations between survey and observational measures, and overlap of PCC with other constructs. We outline problems in operationalizing PCC, choosing tools for assessing PCC, choosing data sources, identifying mediators of PCC, and clarifying outcomes of PCC. We propose nine areas for improvement: (1) developing theory-based operational definitions of PCC; (2) clarifying what is being measured; (3) accounting for the communication behaviors of each individual in the encounter as well as interactions among them; (4) accounting for context; (5) validating of instruments; (6) interpreting patient ratings of their physicians; (7) doing longitudinal studies; (8) examining pathways and mediators of links between PCC and outcomes; and (9) dealing with the complexity of the construct of PCC. We discuss the use of observational and survey measures, multi-method and mixed-method research, and standardized patients. The increasing influence of the PCC literature to guide medical education, licensure of clinicians, and assessments of quality provides a strong rationale for further clarification of these measurement issues.

Emotion language in primary care encounters: reliability and validity of an emotion word count coding system.

OBJECTIVES: To develop a reliable and valid computer coded measure to assess emotional expression from transcripts of physician-patient interactions. METHODS: Physician encounters with two standardized patients (SPs) were audiotaped. Fifty patients from each physician (n = 100 primary care physicians) completed surveys that assessed patients' perceptions of their relationships with physicians. Audio-recordings of 193 patient-physician encounters were transcribed and computer-coded to derive a percent emotion words, and research assistants completed the Measure of Patient-Centered Communication (MPCC). RESULTS: After adjustment for potential confounders, regression analyses revealed physicians' use of emotion words and the MPCC contribute independently to patients' and SPs' perceptions of their relationship with physicians. CONCLUSIONS: The computerized coding of emotion words shows promise as a reliable, valid, and simple method to code transcript data of physician-patient interactions. This method may be expanded to examine other aspects of physician language and does not require coder training.

Patient-centered care and breast cancer survivors' satisfaction with information.

Satisfaction with information is an important patient outcome and may be related to the physician's ability to elicit the patients' concerns, to consider the patients' psychosocial needs, and to involve patients in treatment decision making; these communication techniques have been described under the umbrella of "patient-centered." The aim of this study was to examine the relationship between patient-centered care and satisfaction with information among women with a history of breast cancer. We administered a questionnaire to 182 women who had completed treatment for breast cancer. Our findings suggest that, while breast cancer survivors are highly satisfied with information related to treatment, they are less satisfied with information related to the long-term physical, psychological, and social sequelae of the disease and its treatments. In multivariate analysis, patients' perception of patient-centered behaviors was strongly associated with patients' satisfaction with information. These results provide support for the theory that patient satisfaction is improved when physicians incorporate patient-centered behaviors into their care.

Contributions of physical and sexual abuse to women's experiences with chronic pelvic pain.

OBJECTIVE: To examine the roles of physical and sexual abuse in women with chronic pelvic pain using multi-dimensional pain assessment and to compare the chronic pelvic pain experiences of women with physical abuse to those of women with sexual abuse. STUDY DESIGN: Structured questionnaires were used to measure self-reported abuse, pain severity, psychological distress, physical functioning, interpersonalfunctioning, and coping in 63 women attending a tertiary care gynecologic clinic for diagnosis and treatment of chronic pelvic pain. RESULTS: Women with chronic pelvic pain who reported abuse demonstrated significantly more psychological distress than did women who reported no abuse, but there were no differences in pain severity, physical functioning, interpersonal functioning or coping. Women with physical abuse reported more overall psychological distress, depression, anxiety and somatization than women who reported no physical abuse. Women who reported sexual abuse showed more overall psychological distress and anxiety than women who reported no sexual abuse. While physical abuse was more consistently associated with psychological distress than was sexual abuse, both types of abuse were risk factors for distress. CONCLUSION: These results suggest that both physical and sexual abuse are associated with psychological distress in women with chronic pelvic pain but not with other domains of pain experience. Additional research to improve identification and treatment of women with both chronic pelvic pain and abuse is indicated.

Impact of genetic testing for breast-ovarian cancer susceptibility.

Previously, we have reported a clinical trial in which any woman in a defined geographic region who had a qualifying family history and who was referred by her physician or who was identified through a regional cancer registry was offered free genetic counseling, BRCA testing, and recommendations based on test results. Each family was represented by one affected and one unaffected person. Of the 87 families actually tested, 13 were found to have deleterious mutations. To assess the impact of the counseling and testing process, we contacted the tested individuals 1 month and 1 year after receiving the test result and those with an abnormal test result after 4 years. Index subjects, we found, differed significantly from relatives. Before coming for counseling, index subjects perceived both their general health and emotional health as worse than did their relatives. After counseling and testing, index subjects continue to worry more about breast cancer than do relatives. Affected subjects, we found, differed significantly from unaffected subjects. Before counseling, affected subjects knew more about breast cancer, perceived their general health as poorer, and reported greater adherence to recommended breast cancer surveillance than did unaffected subjects. After counseling and testing, affected subjects were less satisfied than unaffected subjects with having been tested. This study indicates that the group most prone to distress by cancer risk genetic counseling and testing is not the recruited relatives, nor even those affected with cancer, but rather the index patients themselves. The index patients, i.e., the ones who want the risk information most, appear to undergo the most stress in obtaining it.

Patient trust: is it related to patient-centered behavior of primary care physicians?

BACKGROUND: Patients' trust in their health care providers may affect their satisfaction and health outcomes. Despite the potential importance of trust, there are few studies of its correlates using objective measures of physician behavior during encounters with patients. METHODS: We assessed physician behavior and length of visit using audio tapes of encounters of 2 unannounced standardized patients (SPs) with 100 community-based primary care physicians participating in a large managed care organization. Physician behavior was assessed via 3 components of the Measure of Patient-Centered Communication (MPCC) scale. The Primary Care Assessment Survey (PCAS) trust subscale was administered to 50 patients from each physician's practice and to SPs. We used multilevel modeling to examine the associations between physicians' Patient-Centered Communication during the SP visits and ratings of trust by both patients and SPs. RESULTS: Component 1 of the MPCC, which explored the patient's experience of the disease and illness, was independently associated with patient's rating of trust in their physician. A I SD increase in this score was associated with 0.08 SD increase in trust (95% confidence interval 0.02-0.14). Each additional minute spent in SP visits was also independently associated with 0.01 SD increase in patient trust. (95% confidence interval 0.0001-0.02). Component 1 and visit length were also positively associated with SP trust ratings. CONCLUSIONS: Physician verbal behavior during an SP encounter is associated with trust reported by SPs and patients. Research is needed to determine whether interventions designed to enhance physicians' exploration patients' experiences of disease and illness improves trust. Key Words: physician-patient relationship, patient-centered care, trust, physician behavior

A pilot study of an intervention for breast cancer survivors and their spouses.

Recent studies have shown that interventions that increase breast cancer patients' communication with family members lead to reduced patient distress. In this article, we report on a treatment development and pilot study of an intervention for couples coping with breast cancer. In phase 1 of this study, 10 couples participated in two focus groups that generated ideas and themes for the intervention. In phase 2, we developed and pilot tested our intervention with 48 couples: 12 in a 2-session format, 21 in a 1-session format, and 15 in a non-experimental control group. Our response rate shows that breast cancer patients and spouses were willing to participate and that treatment providers were willing to refer patients and their spouses. The 2-session format showed the most promise for producing positive change in mental health functioning and cancer-related stress.

Preliminary reliability and validity of a family caregiver conflict scale for stroke.

Recovery from stroke is a challenging process for stroke survivors and their families. Assessing family conflict may be useful in guiding interventions to reduce caregiver distress. The purpose of this study was to assess preliminary reliability and validity data for a 15-item family caregiver conflict scale [FCCS] for stroke. Construct validity was assessed using subscales from the family assessment device: communication, problem solving, general family functioning, and a perceived criticism scale. Data were pooled from three studies of caregivers of stroke survivors (total N=93). Internal consistency for the FCCS was adequate (>0.70). Higher family conflict was related to more ineffective family communication, general family functioning, and higher perceived criticism (p > or =0.05). Nonspouse caregivers reported more family conflict than spouse caregivers. The FCCS appears to have adequate internal consistency and construct validity and may provide information about family conflicts around stroke recovery and direction for family-focused interventions.

Influence of stroke survivor characteristics and family conflict surrounding recovery on caregivers' mental and physical health.

BACKGROUND: Stroke recovery is a dynamic process for stroke survivors, and shorter lengths of stay in healthcare settings shift the care of the survivors to family caregivers. The physical and mental sequelae after stroke and the family's response to this catastrophic event may have deleterious effects on caregivers. OBJECTIVE: To examine the influence of stroke survivors' motor function, their memory and behavior changes, and the family conflict surrounding stroke recovery on the mental and physical health of caregivers during the subacute recovery period. METHODS: This cross-sectional, correlational study used baseline data from family caregivers (n = 132) and first-time stroke survivors enrolled in a larger multisite study. RESULTS: The caregivers were primarily White (71%), female (74%), college-educated (73%) spouses (80%) of survivors. Most of the caregivers (66%) reported family conflict. The caregivers from families with lower family functioning scores reported worse mental health. The caregivers reported lower mental health when they were caring for stroke survivors with a combination of high memory/behavior changes and low motor function (R =.30). Family conflict appears to exacerbate the impact of memory and behavior changes on caregiver mental health. Higher caregiver education and no major health problems were associated with better caregiver physical health (R =.36). Caregiver physical health was not associated with family functioning or stroke survivor memory and behavior changes. CONCLUSIONS: These results indicate that memory and behavior changes of stroke survivors and family conflict surrounding stroke recovery are important considerations for assessment during the poststroke recovery period.

Physicians' responses to patients' medically unexplained symptoms.

OBJECTIVE: To understand how physicians communicate may contribute to the mistrust and poor clinical outcomes observed in patients who present with medically unexplained symptoms (MUS). METHODS: After providing informed consent, 100 primary care physicians in greater Rochester, New York, were visited by two unannounced covert standardized patients (actors, or SPs) portraying two chest pain roles: classic symptoms of gastroesophageal reflux disease (GERD) with nausea and insomnia (the GERD role) and poorly characterized chest pain with fatigue and dizziness (the MUS role). The visits were surreptitiously audiorecorded and analyzed using the Measure of Patient-Centered Communication (MPCC), which scores physicians on their exploration of the patients' experience of illness (component 1) and psychosocial context (component 2), and their attempts to find common ground on diagnosis and treatment (component 3). RESULTS: In multivariate analyses, MUS visits yielded significantly lower scores on MPCC component 1 (p = .01). Subanalysis of component 1 scores showed that patients' symptoms were not explored as fully and that validation was less likely to be used in response to patient concerns in the MUS than in the GERD visits. Component 2 and component 3 were unchanged. CONCLUSION: Physicians' inquiry into and validation of symptoms in patients with MUS was less common compared with more medically straightforward patient presentations. Further research should study the relationship between communication variables and poor clinical outcomes, misunderstandings, mutual distrust, and inappropriate healthcare utilization in this population, and test interventions to address this problem.

Are patients' ratings of their physicians related to health outcomes?

PURPOSE: Observational studies using patient reports suggest associations between physician interpersonal styles and patient outcomes. Possible confounding of these associations has not been carefully examined. METHODS: Approximately 4,700 patients of 96 physicians completed a survey instrument that included reported health status changes during the previous year, perceptions of their physician (satisfaction, trust, knowledge of patient, and autonomy support), and sociodemographic and clinical covariates. We examined the adjusted relationship between patient perceptions of their physicians and reported health status changes. Using multilevel analyses, we then explored differences among physicians in patient perceptions of their physicians and whether these differences were explained by the relationship between patient perceptions and reported health status changes. RESULTS: There were significant adjusted relationships between patient perceptions of their physician and reported health status changes: better perceptions were associated with a smaller risk of health status decline (adjusted odds ratio = 1.14; 95% confidence interval [CI], 1.05-1.24; P <.01). Multilevel analysis showed significant differences between physicians in patient perceptions of their physicians (rho = 0.10; 95% CI, 0.07-0.13; P <.01), but these physician differences were unrelated to reported health status decline (rho = 0; P >.99). CONCLUSIONS: Using methods similar to those of previous studies, we found a relationship between patient perceptions of their physicians and reported health status declines. Multilevel analysis, however, suggested that this relationship is not a physician effect; it may reflect unmeasured patient confounding. Multilevel analyses may help to examine the relationships between physician styles and outcomes.

Rochester Participatory Decision-Making Scale (RPAD): reliability and validity.

PURPOSE: We wanted develop a reliable and valid objective measure of patient-physician collaborative decision making, the Rochester Participatory Decision-Making Scale (RPAD). METHODS: Based on an informed decision-making model, the RPAD assesses physician behavior that encourages patient participation in decision making. Data were from a study of physician-patient communication of 100 primary care physicians. Physician encounters with 2 standardized patients each were audio recorded, resulting in 193 useable recordings. Transcribed recordings were coded both with RPAD and the Measure of Patient-Centered Communication (MPCC), which includes a related construct, Finding Common Ground. Two sets of dependent variables were derived from (1) surveys of the standardized patients and (2) surveys of 50 patients of each physician, who assessed their perceptions of the physician-patient relationship. RESULTS: The RPAD was coded reliably (intraclass correlation coefficient [ICC] = 0.72). RPAD correlated with Finding Common Ground (r = 0.19, P < .01) and with the survey measures of standardized patient's perceptions of the physician-patient relationship (r = 0.32 - 0.36 [P < .005]) but less with the patient survey measures (r = 0.06 to 0.07 [P < .005]). Multivariate, hierarchical analyses suggested that the RPAD made a more robust contribution to explaining variance in standardized patient perceptions than did the MPCC Finding Common Ground. CONCLUSIONS: The RPAD shows promise as a reliable, valid, and easy-to-code objective measure of participatory decision making.

Patient-centered communication and diagnostic testing.

PURPOSE: Although patient-centered communication is associated with improved health and patient trust, information about the impact of patient-centered communication on health care costs is limited. We studied the relationship between patient-centered communication and diagnostic testing expenditures. METHODS: We undertook an observational cross-sectional study using covert standardized patient visits to study physician interaction style and its relationship to diagnostic testing costs. Participants were 100 primary care physicians in the Rochester, NY, area participating in a large managed care organization (MCO). Audio recordings of 2 standardized patient encounters for each physician were rated using the Measure of Patient-Centered Communication (MPCC). Standardized diagnostic testing and other expenditures, adjusted for patient demographics and case-mix, were derived from the MCO claims database. Analyses were adjusted for demographics and standardized patient detection. RESULTS: Compared with other physicians, those who had MPCC scores in the lowest tercile had greater standardized diagnostic testing expenditures (11.0% higher, 95% confidence interval [CI], 4.5%-17.8%) and greater total standardized expenditures (3.5% higher, 95% CI, 1.0%-6.1%). Whereas lower MPCC scores were associated with shorter visits, adjustment for visit length and standardized patient detection did not affect the relationship with expenditures. Total (testing, ambulatory and hospital care) expenditures were also greater for physicians who had lower MPCC scores, an effect primarily associated with the effect on testing expenditures. CONCLUSIONS: Patient-centered communication is associated with fewer diagnostic testing expenditures but also with increased visit length. Because costs and visit length may affect physicians' and health systems' willingness to endorse and practice a patient-centered approach, these results should be confirmed in future randomized trials.
