Mental health and health-related quality of life among adult Latino primary care patients living in the United States with previous exposure to political violence.

CONTEXT: Although political violence continues in parts of Central America, South America, and Mexico, little is known about its relationship to the health of Latino immigrants living in the United States. OBJECTIVE: To determine (1) rates of exposure to political violence among Latino adult primary care patients who have immigrated to the United States from Central America, South America, and Mexico and its impact on mental health and health-related quality of life and (2) frequency of disclosure of political violence to primary care clinicians. DESIGN, SETTING, AND PARTICIPANTS: Two-stage cluster design survey of a systematic sample of Latino immigrant adults in 3 community-based primary care clinics in Los Angeles, conducted from July 2001 to February 2002. MAIN OUTCOME MEASURES: Reports of exposure to political violence in home country before immigrating to the United States and communication with clinicians about political violence; self-reported measures of health-related quality of life using the Medical Outcomes Study Short Form 36 (MOS SF-36); symptoms of depression, anxiety, and alcohol disorders using the Primary Care Evaluation of Mental Disorders (PRIME-MD); and symptoms of posttraumatic stress disorder (PTSD) using the PTSD Checklist-Civilian Version (PCL-C). RESULTS: A total of 638 (69%) of 919 eligible patients participated. The nonresponse rates did not differ by age, sex, recruitment sites, or clinic sessions. In weighted analyses, 54% of participants reported political violence experiences in their home countries, including 8% who reported torture. Of those exposed to political violence, 36% had symptoms of depression and 18% had symptoms of PTSD vs 20% and 8%, respectively, among those not exposed to political violence. Controlling for age, sex, country, years lived in the United States, acculturation, income, health insurance status, and recruitment site in a subsample of 512 participants (56%), those who reported political violence exposure were more likely to meet symptom criteria for PTSD (adjusted odds ratio [AOR], 3.4; 95% confidence interval [CI], 1.4-8.4) and to have symptoms of depression (AOR, 2.8; 95% CI, 1.4-5.4) and symptoms of panic disorder (AOR, 4.8; 95% CI, 1.6-14.4) than participants not reporting political violence. Those exposed to political violence reported more chronic pain and role limitations due to physical problems, as well as worse physical functioning and lower perceptions of general health than those who were not exposed to political violence. Only 3% of the 267 patients who had experienced political violence reported ever telling a clinician about it after immigrating; none reported their current physician asking about political violence. CONCLUSION: Latino immigrants in primary care in Los Angeles have a high prevalence of exposure to political violence before immigrating to the United States and associated impairments in mental health and health-related quality of life.

Adherence to directly observed antiretroviral therapy among human immunodeficiency virus-infected prison inmates.

Directly observed therapy (DOT) for human immunodeficiency virus (HIV) infection is commonly used in correctional settings; however, the efficacy of DOT for treating HIV infection has not been determined. We prospectively assessed adherence to antiretroviral therapy regimens among 31 HIV-infected prison inmates who were receiving >or=1 antiretrovirals via DOT. Adherence was measured by self-report, pill count, electronic monitoring caps, and, for DOT only, medication administration records. Overall, median adherence was 90%, as measured by pill count; 86%, by electronic monitoring caps; and 100%, by self-report. Adherence, as measured by electronic monitoring caps, was >90% in 32% of the subjects. In 91% of cases, adherence, as measured by medication administration records, was greater than that recorded by electronic monitoring caps for the same medications administered by DOT. Objective methods of measurement revealed that adherence to antiretroviral regimens administered wholly or in part by DOT was <or=90% in more than one-half of the patients. Different methods used to measure adherence revealed significantly different levels of adherence. These findings suggest that use of DOT does not ensure adherence to antiretroviral therapy.

Complementary and alternative medicine use and substitution for conventional therapy by HIV-infected patients.

BACKGROUND: HIV-infected patients commonly use complementary and alternative medicine (CAM), but it is not known how often CAM is used as a complement or as a substitute for conventional HIV therapy. OBJECTIVES: To evaluate the prevalence and factors associated with CAM use with potential for adverse effects and CAM substitution for conventional HIV medication. DESIGN AND PARTICIPANTS: Cross-sectional survey of U.S. national probability sample of HIV-infected patients (2,466 adults) in care from December 1996 to July 1997. MAIN OUTCOME VARIABLES: Any CAM use, CAM use with potential for adverse effects, and use of CAM as a substitute for conventional HIV therapy. Substitution was defined as replacement of some or all conventional HIV medications with CAM. RESULTS: Fifty-three percent of patients had recently used at least one type of CAM. One quarter of patients used CAM with the potential for adverse effects, and one-third had not discussed such use with their health care provider. Patients with a greater desire for medical information and involvement in medical decision making and with a negative attitude toward antiretrovirals were more likely to use CAM. Three percent of patients substituted CAM for conventional HIV therapy. They were more likely to desire involvement in medical decision-making (odds ratio, 1.8; 95% confidence interval, 1.0-3.2) and to have a negative attitude toward antiretrovirals (odds ratio, 7.8; 95% confidence interval, 3.0-19.0). CONCLUSIONS: Physicians should openly ask HIV-infected patients about CAM use to prevent adverse effects and to identify CAM substitution for conventional HIV therapy.

Knowledge of antiretroviral regimen dosing and adherence: a longitudinal study.

In a cohort of 128 human immunodeficiency virus-infected patients, we found that patients' knowledge of antiretroviral dosing was suboptimal at regimen initiation but improved with time. Poor medication knowledge 8 weeks after regimen initiation was associated with lower adherence and with a lower level of literacy in a multivariate model (P=.03). Because knowledge deficits are common after antiretroviral regimen initiation, clinicians should assess patients' understanding of medication dosing soon after regimen initiation or change.

Waiting times in California's emergency departments.

STUDY OBJECTIVE: Many perceive emergency department crowding as a significant problem that is getting worse. A national survey of ED directors defined crowding, in part, as waiting more than 1 hour to see a physician, a wait considered likely to result in adverse outcomes. Yet few data are available on ED waiting times among a heterogeneous group of hospitals serving a distinct geographic region. METHODS: We observed a random sample of 1,798 patients visiting 30 California EDs between December 15, 2000, and May 15, 2001. We defined waiting time as the interval from ED arrival to first contact with a physician or midlevel provider. RESULTS: Patients waited an average of 56 minutes (95% confidence interval [CI] 52 to 61 minutes; median 38 minutes); 42% waited longer than 60 minutes. Ordinary least squares regression analysis revealed that waiting times were significantly longer at hospitals in poorer neighborhoods: For every 10,000 dollars decline in per capita income, patients waited 10.1 minutes longer (95% CI 1.8 to 18.4 minutes; P=.02) after adjusting for hospital ownership, teaching status, trauma status, proximity to a recently closed ED, ED volume, patient severity, and age. Lower ratios of physicians and triage nurses to waiting room patient were also associated with longer waits. CONCLUSION: Waiting times often exceeded the threshold set by a survey of ED directors. Further study is required to examine factors that lead to longer waiting times at hospitals in low-income areas. Physician and nurse staffing should be investigated as a means of reducing waiting times.

Methodological challenges associated with patient responses to follow-up longitudinal surveys regarding quality of care.

OBJECTIVE: To illustrate, using empirical data, methodological challenges associated with patient responses to longitudinal surveys regarding the quality of process of care and health status, including overall response rate, differential response rate, and stability of responses with time. DATA SOURCES/STUDY SETTING: Primary patient self-report data were collected from 30,308 patients in 1996 and 13,438 patients in 1998 as part of a two-year longitudinal study of quality of care and health status of patients receiving care delivered by 63 physician organizations (physician groups) across three West Coast states. STUDY DESIGN: We analyzed longitudinal, observational data collected by Pacific Business Group on Health (PBGH) from patients aged 18-70 using a four-page survey in 1996 and a similar survey in 1998 to assess health status, satisfaction, use of services, and self-reported process of care. A subset of patients with self-reported chronic disease in the 1996 study received an enriched survey in 1998 to more fully detail processes of care for patients with chronic disease. DATA COLLECTION/EXTRACTION METHODS: We measured response rate overall and separately for patients with chronic disease. Logistic regression was used to assess the impact of 1996 predictors on response to the follow-up 1998 survey. We compared process of care scores without and with nonresponse weights. Additionally, we measured stability of patient responses over time using percent agreement and kappa statistics, and examined rates of gender inconsistencies reported across the 1996 and 1998 surveys. PRINCIPAL FINDINGS: In 1998, response rates were 54 percent overall and 63 percent for patients with chronic disease. Patient demographics, health status, use of services, and satisfaction with care in 1996 were all significant predictors of response in 1998, highlighting the importance of analytic strategies (i.e., application of nonresponse weights) to minimize bias in estimates of care and outcomes associated with longitudinal quality of care and health outcome analyses. Process of care scores weighted for nonresponse differed from unweighted scores (p<.001). Stability of responses across time was moderate, but varied by survey item from fair to excellent. CONCLUSIONS: Longitudinal analyses involving the collection of data from the same patients at two points in time provide opportunities for analysis of relationships between process and outcomes of care that cannot occur with cross-sectional data. We present empirical results documenting the scope of the problems and discuss options for responding to these challenges. With increasing emphasis in the United States on quality reporting and use of financial incentives for quality in the health care market, it is important to identify and address methodological challenges that potentially threaten the validity of quality-of-care assessments.

Life satisfaction and adverse effects in renal transplant recipients: a longitudinal analysis.

INTRODUCTION: Previous cross-sectional analyses have identified significant associations between quality of life (QOL), comorbidities and adverse effects in renal transplant recipients. This report examines the longitudinal relationship between adverse effects and QOL, with particular attention to the relative impact of adverse effects associated with immunosuppression. METHODS: The Transplant Learning Center (TLC) is a program designed to improve QOL and preserve graft function in transplant recipients. Self-selected enrollees filled out questionnaires at roughly 3-month intervals. Each questionnaire included QOL scales developed for the program. Repeated measures multiple regression analysis was used to examine the relationship between the QOL scales, comorbidities, adverse effects, adjusting for other factors. RESULTS: A total of 4247 TLC enrollees were included in the analysis, with a mean time since transplant of 5.1 yr. Comorbidities and adverse effects were common, with high blood pressure reported by 87% of respondents and unusual hair growth reported by 69.6%. In bivariate analysis, emotional/psychological problems and headaches had the largest impact on QOL. In multivariate analysis, emotional/psychological problems decreased sexual interest or ability, and headache had the largest adverse QOL effect. CONCLUSIONS: We have identified QOL issues that have been previously underemphasized in transplant recipients. These findings open new areas of research to further explore and define these issues. They provide new opportunities for interventions to address factors adversely impacting QOL and to develop strategies to improve QOL in these patients. Clinicians should actively solicit information about adverse effects of medications, particularly information about sexual and relationship issues, when evaluating renal recipients. These issues should be taken into account when making therapeutic decisions.

How well do clinicians estimate patients' adherence to combination antiretroviral therapy?

OBJECTIVE: Adherence to combination antiretroviral therapy is critical for clinical and virologic success in HIV-infected patients. To combat poor adherence, clinicians must identify nonadherent patients so they can implement interventions. However, little is known about the accuracy of these assessments. We sought to describe the accuracy of clinicians' estimates of patients' adherence to combination antiretroviral therapy. SETTING: Public HIV clinic. DESIGN: Prospective cohort study. During visits, we asked clinicians (nurse practitioners, residents and fellows, and their supervising attending physicians) to estimate the percentage of antiretroviral medication taken by patients over the last 4 weeks and predicted adherence over the next 4 weeks. Adherence was measured using electronic monitoring devices, pill counts, and self-reports, which were combined into a composite adherence measure. PATIENTS AND PARTICIPANTS: Clinicians estimated 464 episodes of adherence in 82 patients. RESULTS: Among the 464 adherence estimates, 264 (57%) were made by principal care providers (31% by nurse practitioners, 15% by fellows, 6% by residents, and 5% by staff physicians) and 200 (43%) by supervising attending physicians. Clinicians' overestimated measured adherence by 8.9% on average (86.2% vs 77.3%). Greater clinician inaccuracy in adherence prediction was independently associated with higher CD4 count nadir (1.8% greater inaccuracy for every 100 CD4 cells, P=.005), younger patient age (3.7% greater inaccuracy for each decade of age, P=.02), and visit number (P=.02). Sensitivity of detecting nonadherent patients was poor (24% to 62%, depending on nonadherence cutoff). The positive predictive value of identifying a patient as nonadherent was 76% to 83%. CONCLUSIONS: Clinicians tend to overestimate medication adherence, inadequately detect poor adherence, and may therefore miss important opportunities to intervene to improve antiretroviral adherence.

Acculturation of attitudes toward end-of-life care: a cross-cultural survey of Japanese Americans and Japanese.

OBJECTIVE: Cross-cultural ethical conflicts are common. However, little is known about how and to what extent acculturation changes attitudes toward end-of-life care and advance care planning. We compared attitudes toward end-of-life care among Japanese Americans and Japanese in Japan. DESIGN: Self-administered questionnaire in English and Japanese. SETTING AND PARTICIPANTS: Community-based samples of Japanese Americans in Los Angeles and Japanese in Nagoya, Japan: 539 English-speaking Japanese Americans (EJA), 340 Japanese-speaking Japanese Americans (JJA), and 304 Japanese living in Japan (JJ). MEASUREMENTS AND MAIN RESULTS: Few subjects (6% to 11%) had discussed end-of-life issues with physicians, while many (EJA, 40%; JJA, 55%; JJ, 54%) desired to do so. Most preferred group surrogate decision making (EJA, 75%; JJA, 57%; JJ, 69%). After adjustment for demographics and health status, desire for informing the patient of a terminal prognosis using words increased significantly with acculturation (EJA, odds ratio [OR] 8.85; 95% confidence interval, [95% CI] 5.4 to 14.3; JJA, OR 2.8; 95% CI 1.8 to 4.4; JJ, OR 1.0). EJA had more-positive attitudes toward forgoing care, advance care planning, and autonomous decision making. CONCLUSION: Preference for disclosure, willingness to forgo care, and views of advance care planning shift toward western values as Japanese Americans acculturate. However, the desire for group decision making is preserved. Recognition of the variability and acculturation gradient of end-of-life attitudes among Japanese Americans may facilitate decision making and minimize conflicts. Group decision making should be an option for Japanese Americans.

A prospective study of predictors of adherence to combination antiretroviral medication.

OBJECTIVE: Adherence to complex antiretroviral therapy (ART) is critical for HIV treatment but difficult to achieve. The development of interventions to improve adherence requires detailed information regarding barriers to adherence. However, short follow-up and inadequate adherence measures have hampered such determinations. We sought to assess predictors of long-term (up to 1 year) adherence to newly initiated combination ART using an accurate, objective adherence measure. DESIGN: A prospective cohort study of 140 HIV-infected patients at a county hospital HIV clinic during the year following initiation of a new highly active ART regimen. MEASURES AND MAIN RESULTS: We measured adherence every 4 weeks, computing a composite score from electronic medication bottle caps, pill count and self-report. We evaluated patient demographic, biomedical, and psychosocial characteristics, features of the regimen, and relationship with one's HIV provider as predictors of adherence over 48 weeks. On average, subjects took 71% of prescribed doses with over 95% of patients achieving suboptimal (<95%) adherence. In multivariate analyses, African-American ethnicity, lower income and education, alcohol use, higher dose frequency, and fewer adherence aids (e.g., pillboxes, timers) were independently associated with worse adherence. After adjusting for demographic and clinical factors, those actively using drugs took 59% of doses versus 72% for nonusers, and those drinking alcohol took 66% of doses versus 74% for nondrinkers. Patients with more antiretroviral doses per day adhered less well. Participants using no adherence aids took 68% of doses versus 76% for those in the upper quartile of number of adherence aids used. CONCLUSIONS: Nearly all patients' adherence levels were suboptimal, demonstrating the critical need for programs to assist patients with medication taking. Interventions that assess and treat substance abuse and incorporate adherence aids may be particularly helpful and warrant further study.

Trends in the use and capacity of California's emergency departments, 1990-1999.

STUDY OBJECTIVE: Concerns over the ability of the nation's emergency departments to meet current demands are growing among the public and health care professionals. Data supporting perceptions of inadequate capacity are sparse and conflicting. We describe changes in the use and capacity of California's EDs between 1990 and 1999, as well as trends in severity of patient illness or injury. METHODS: Data from California's Office of Statewide Health Planning and Development (OSHPD), which describe all hospital and health service use in the state, were analyzed and later verified using a telephone survey of all 320 open EDs in California. Six variables were analyzed: hospital's ownership type (public or private), total number of annual ED visits, severity of patient illness or injury (percentage of visits categorized as critical, urgent, or nonurgent), number of ED beds, proximity to a closed ED, and teaching status. We tested 2 main hypotheses: (1) Have statewide ED visits, ED beds, visits per ED, and visits per bed increased or decreased between 1990 and 1999? and (2) Has severity of patient illness or injury, as reported to OSHPD, changed over the past decade? State level data were analyzed using ordinary least-squares regression. Hospital level data were analyzed using repeated measures analyses. RESULTS: The number of EDs in California decreased by 12% (P <.0001). The number of ED treatment stations (ie, physical spaces for the treatment of patients) increased by 687 (16%) statewide (P =.0001), or an average of 79 beds per year. The average annual change in ED visits was not statistically significant (P =.5), whereas visits per ED increased by 27% for all EDs (P <.0001), although with differing trends noted at public and private hospitals. At private hospitals, the average increase was 512 visits/ED each year, whereas at public hospitals, visits decreased by an average of 1,085 visits/ED each year (P <.0001). Overall, critical visits per ED increased by 59% (P <.0001), and nonurgent visits per ED decreased by 8% (P <.0001). CONCLUSION: The number of EDs in California decreased significantly during the 1990s, whereas the number of ED beds increased. Increases in visits per ED, beds per ED, and in the proportion of patients categorized as critical may help explain the perception that ED capacity is inadequate to meet growing demand.

The influence of military service on outpatient care use among racial/ethnic groups in Department of Veterans Affairs medical centers.

This study examines race-specific military service effects on outpatient care utilization in the Department of Veterans Affairs (VA) using data from the 1992 National Survey of Veterans. The study population consisted of 4,791 male veterans. After controlling for predisposing, enabling, and need variables, black veterans were 3.7 times more likely than white veterans to use VA outpatient care. Veterans discharged from the military for medical release were less likely to use VA outpatient care (odds ratio = 0.76) than veterans discharged at the end of their normal terms. Hispanic veterans discharged for medical release were 5.3 times more likely than white veterans discharged for the same reason to use VA outpatient care. Korean conflict and mixed war period veterans were more likely to use VA outpatient care than World War II veterans. Racial/ethnic differences in military service characteristics influence the use of VA outpatient care and should be understood in delivering outpatient care to veterans.

[The preliminary study on creating the differential templates of the skeletal profiles for Shanghainese with normal occlusion in early permanent dentition].

OBJECTIVE: To establish the differential templates of the skeletal profiles for Shanghainese with normal occlusion in early permanent dentition. METHODS: 71 lateral cephalometric radiographs of subjects with normal occlusion in early permanent dentition, aged from 11 - 15 years (37 females and 34 males) were traced. 23 skeletal landmarks were identified on the tracings, which afterwards were scanned on the computer. An x-y coordinate system was established: the tracing superimposed on sella rotated 7 degrees down from the sella-nasion line as the x axis and the vertical line through sella perpendicular to the x axis as the y axis. A special length/depth ratio was designed. The length/depth ratio of each graph were calculated. Steiner analysis was applied to check the difference between genders. RESULTS: There was no difference between genders. The tracings were divided into three categories: short face, normal face and long face according to the mean and standard deviation of the ratio. The three types of tracings were superimposed on the x axis with sella registered. Three templates were created. CONCLUSIONS: The differences were apparent when the three templates were superimposed.

Does Acculturation Influence Physical Activity in Japanese American Older Adults?

PURPOSE: Despite the health benefits of physical activity, demographic and health factors as well as cultural backgrounds are thought to influence participation in physical activity. The aim of this study is to examine whether acculturation is associated with physical activity in a sample of Japanese American older adults living on the continental United States. METHODS: A survey was mailed to Japanese Americans identified from the mailing list of two community&shy;based organizations. The survey included questions on physical activity, acculturation, demographics, health behaviors, and self&shy;reported health status. Data were analyzed using bivariate and multiple regression techniques. FINDINGS: Acculturation was not a significant predictor of phsical activity in either community sample, or the pooled sample, after conrolling for other sociodemographic andhealth status variables. The models explained 23% to 2% of the variance in physical activity. Statistically significant predictors of physical activity included gender, work status, age, income, and health status. CONCLUSIONS: Our findings differ from studies of Japanese Americans in Hawaii and other racial/ethnic groups, suggesting that accultraion may have differential effects depending on the environment and the racial/ethnic group under study. KEY WORDS: Japanese American, physical activity, acculturation

Variation in the readability of items within surveys.

The objective of this study was to estimate the variation in the readability of survey items within 2 widely used health-related quality-of-life surveys: the National Eye Institute Visual Functioning Questionnaire-25 (VFQ-25) and the Short Form Health Survey, version 2 (SF-36v2). Flesch-Kincaid and Flesch Reading Ease formulas were used to estimate readability. Individual survey item scores and descriptive statistics for each survey were calculated. Variation of individual item scores from the mean survey score was graphically depicted for each survey. The mean reading grade level and reading ease estimates for the VFQ-25 and SF-36v2 were 7.8 (fairly easy) and 6.4 (easy), respectively. Both surveys had notable variation in item readability; individual item readability scores ranged from 3.7 to 12.0 (very easy to difficult) for the VFQ-25 and 2.2 to 12.0 (very easy to difficult) for the SF-36v2. Because survey respondents may not comprehend items with readability scores that exceed their reading ability, estimating the readability of each survey item is an important component of evaluating survey readability. Standards for measuring the readability of surveys are needed.

Impact of antiretroviral regimen switches on adherence.

PURPOSE: An understanding of the situations in which adherence lapses occur is critical to the design of effective interventions to enhance adherence. We investigated whether a switch in antiretroviral medications affected adherence by examining a prospective observational cohort of 128 patients who began a new antiretroviral regimen. METHOD: Adherence was measured using electronic devices, pill counts, and self-reports, which were combined into a composite adherence measure and expressed as the proportion of prescribed medication taken. RESULTS: During 1,056 person-months of follow-up, 129 medication regimen changes occurred among 84 patients (66% of participants). Among the 89 analyzable switches (representing 66 patients), the most common reasons for switch included pill to liquid ritonavir (n = 26), gastrointestinal intolerance (n = 11), virologic failure (n = 8), and peripheral neuropathy (n = 7). Overall, mean adherence prior to regimen switch exceeded mean adherence after regimen switch (0.75 vs. 0.70; p =.035). Among subgroups of switches, adherence decreased significantly after switching from pill to liquid ritonavir (0.83 vs. 0.68; p <.001). When this group was excluded, there was no change in adherence after switches (0.72 vs. 0.71; p =.74). CONCLUSION: Antiretroviral regimen changes are not associated with adherence improvement and may be associated with declining adherence when a new regimen is unpalatable. Antiretroviral regimen changes should trigger reassessment of adherence and, when appropriate, adherence intervention.

Trust in one's physician: the role of ethnic match, autonomy, acculturation, and religiosity among Japanese and Japanese Americans.

PURPOSE: Trust is a cornerstone of the physician-patient relationship. We investigated the relation of patient characteristics, religiosity, acculturation, physician ethnicity, and insurance-mandated physician change to levels of trust in Japanese American and Japanese patients. METHODS: A self-administered, cross-sectional questionnaire in English and Japanese (completed in the language of their choice) was given to community-based samples of 539 English-speaking Japanese Americans, 340 Japanese-speaking Japanese Americans, and 304 Japanese living in Japan. RESULTS: Eighty-seven percent of English-speaking Japanese Americans, 93% of Japanese-speaking Japanese Americans, and 58% of Japanese living in Japan responded to trust items and reported mean trust scores of 83, 80, and 68, respectively, on a scale ranging from 0 to 100. In multivariate analyses, English-speaking and Japanese-speaking Japanese American respondents reported more trust than Japanese respondents living in Japan (P values <.001). Greater religiosity (P <.001), less desire for autonomy (P <.001), and physician-patient relationships of longer duration (P <.001) were related to increased trust. Among Japanese Americans, more acculturated respondents reported more trust (P <.001), and Japanese physicians were trusted more than physicians of another ethnicity. Among respondents prompted to change physicians because of insurance coverage, the 48% who did not want to switch reported less trust in their current physician than in their former physician (mean score of 82 vs 89, P <.001). CONCLUSIONS: Religiosity, autonomy preference, and acculturation were strongly related to trust in one's physician among the Japanese American and Japanese samples studied and may provide avenues to enhance the physician-patient relationship. The strong relationship of trust with patient-physician ethnic match and the loss of trust when patients, in retrospect, report leaving a preferred physician suggest unintended consequences to patients not able to continue with their preferred physicians.
