Vacation Days Taken, Work During Vacation, and Burnout Among US Physicians.

Importance: Vacation has been shown to be an important restorative activity in the general population; less is known about physicians' vacation behaviors and their association with burnout and professional fulfillment. Objective: To examine the number of vacation days taken per year and the magnitude of physician work while on vacation and their association with physician burnout and professional fulfillment, by individual and organizational characteristics. Design, Setting, and Participants: This cross-sectional survey of US physicians was conducted between November 20, 2020, and March 23, 2021. Data analysis was performed from March to July 2023. Main Outcomes and Measures: Burnout was measured using the Maslach Burnout Index, and professional fulfillment was measured using the Stanford Professional Fulfillment Index. Number of vacation days taken in the last year, time spent working on patient care and other professional tasks per typical vacation day (ie, work on vacation), electronic health record (EHR) inbox coverage while on vacation, barriers to taking vacation, and standard demographics were collected. Results: Among 3024 respondents, 1790 of 3004 (59.6%), took 15 or fewer days of vacation in the last year, with 597 of 3004 (19.9%) taking 5 or fewer days. The majority, 2104 respondents (70.4%), performed patient care-related tasks on vacation, with 988 of 2988 (33.1%) working 30 minutes or more on a typical vacation day. Less than one-half of physicians (1468 of 2991 physicians [49.1%]) reported having full EHR inbox coverage while on vacation. On multivariable analysis adjusting for personal and professional factors, concern about finding someone to cover clinical responsibilities (odds ratio [OR], 0.48 [95% CI, 0.35-0.65] for quite a bit; OR, 0.30 [95% CI, 0.21-0.43] for very much) and financial concerns (OR, 0.49 [95% CI, 0.36-0.66] for quite a bit; OR, 0.38 [95% CI, 0.27-0.54] for very much) were associated with decreased likelihood of taking more than 3 weeks of vacation per year. Taking more than 3 weeks of vacation per year (OR, 0.66 [95% CI, 0.45-0.98] for 16-20 days; OR, 0.59 [95% CI, 0.40-0.86] for >20 days vs none) and having full EHR inbox coverage while on vacation (OR, 0.74; 95% CI, 0.63-0.88) were associated with lower rates of burnout on multivariable analysis, whereas spending 30 minutes or longer per vacation day on patient-related work (OR, 1.58; 95% CI, 1.22-2.04 for 30-60 minutes; OR, 1.97; 95% CI, 1.41-2.77 for 60-90 minutes; OR, 1.92; 95% CI, 1.36-2.73 for >90 minutes) was associated with higher rates of burnout. Conclusions and Relevance: In this cross-sectional study of 3024 physicians, the number of vacation days taken and performing patient-related work while on vacation were associated with physician burnout. System-level efforts to ensure physicians take adequate vacation and have coverage for clinical responsibilities, including EHR inbox, may reduce physician burnout.

Changes in Burnout and Satisfaction With Work-Life Integration in Physicians During the First 2 Years of the COVID-19 Pandemic.

OBJECTIVE: To evaluate the prevalence of burnout and satisfaction with work-life integration (WLI) in US physicians at the end of 2021, roughly 21 months into the COVID-19 pandemic, with comparison to 2020, 2017, 2014, and 2011. METHODS: Between December 9, 2021, and January 24, 2022, we surveyed US physicians using methods similar to those of our prior studies. Burnout, WLI, depression, and professional fulfillment were assessed with standard instruments. RESULTS: There were 2440 physicians who participated in the 2021 survey. Mean emotional exhaustion and depersonalization scores were higher in 2021 than those observed in 2020, 2017, 2014, and 2011 (all P<.001). Mean emotional exhaustion scores increased 38.6% (2020 mean, 21.0; 2021 mean, 29.1; P<.001), whereas mean depersonalization scores increased 60.7% (2020 mean, 6.1; 2021 mean, 9.8; P<.001). Overall, 62.8% of physicians had at least 1 manifestation of burnout in 2021 compared with 38.2% in 2020, 43.9% in 2017, 54.4% in 2014, and 45.5% in 2011 (all P<.001). Although these trends were consistent across nearly all specialties, substantial variability by specialty was observed. Satisfaction with WLI declined from 46.1% in 2020 to 30.2% in 2021 (P<.001). Mean scores for depression increased 6.1% (2020 mean, 49.54; 2021 mean, 52.59; P<.001). CONCLUSION: A dramatic increase in burnout and decrease in satisfaction with WLI occurred in US physicians between 2020 and 2021. Differences in mean depression scores were modest, suggesting that the increase in physician distress was overwhelmingly work related. Given the association of physician burnout with quality of care, turnover, and reductions in work effort, these findings have profound implications for the US health care system.

Imposter Phenomenon in US Physicians Relative to the US Working Population.

OBJECTIVE: To determine the prevalence of imposter phenomenon (IP) experiences among physicians and evaluate their relationship to personal and professional characteristics, professional fulfillment, burnout, and suicidal ideation. PARTICIPANTS AND METHODS: Between November 20, 2020, and February 16, 2021, we surveyed US physicians and a probability-based sample of the US working population. Imposter phenomenon was measured using a 4-item version of the Clance Imposter Phenomenon Scale. Burnout and professional fulfillment were measured using standardized instruments. RESULTS: Among the 3237 physician responders invited to complete the subsurvey including the IP scale, 3116 completed the IP questions. Between 4% (133) and 10% (308) of the 3116 physicians endorsed each of the 4 IP items as a "very true" characterization of their experience. Relative to those with a low IP score, the odds ratio for burnout among those with moderate, frequent, and intense IP was 1.28 (95% CI, 1.04 to 1.58), 1.79 (95% CI, 1.38 to 2.32), and 2.13 (95% CI, 1.43 to 3.19), respectively. A similar association between IP and suicidal ideation was observed. On multivariable analysis, physicians endorsed greater intensity of IP than workers in other fields in response to the item, "I am disappointed at times in my present accomplishments and think I should have accomplished more." CONCLUSION: Imposter phenomenon experiences are common among US physicians, and physicians have more frequent experiences of disappointment in accomplishments than workers in other fields. Imposter phenomenon experiences are associated with increased burnout and suicidal ideation and lower professional fulfillment. Systematic efforts to address the professional norms and perfectionistic attitudes that contribute to this phenomenon are necessary.

Changes in Burnout and Satisfaction With Work-Life Integration in Physicians and the General US Working Population Between 2011 and 2020.

OBJECTIVE: To evaluate the prevalence of burnout and satisfaction with work-life integration (WLI) among physicians and US workers in 2020 relative to 2011, 2014, and 2017. METHODS: Between November 20, 2020, and March 23, 2021, we surveyed US physicians and a probability-based sample of the US working population using methods similar to our prior studies. Burnout and WLI were measured using standard tools. Information about specific work-related COVID-19 experiences was collected. RESULTS: There were 7510 physicians who participated in the survey. Nonresponder analysis suggested that participants were representative of US physicians. Mean emotional exhaustion and depersonalization scores were lower in 2020 than in 2017, 2014, and 2011 (all P<.001). However, emotional exhaustion and depersonalization scores did not improve in specialties most heavily affected by COVID-19. Overall, 38.2% of physicians reported 1 or more symptoms of burnout in 2020 compared with 43.9% in 2017, 54.4% in 2014, and 45.5% in 2011 (all P<.001). Providing care without adequate personal protective equipment (odds ratio [OR], 1.53; 95% CI, 1.35 to 1.72) and having suffered disruptive economic consequences due to COVID-19 (OR, 1.49; 95% CI, 1.32 to 1.69) were independently associated with risk of burnout. On multivariable analysis, physicians were at increased risk for burnout (OR, 1.41; 95% CI, 1.25 to 1.58) and were less likely to be satisfied with WLI (OR, 0.71; 95% CI, 0.64 to 0.79) than other working US adults. CONCLUSION: Burnout and satisfaction with WLI among US physicians improved between 2017 and 2020. The impact of the COVID-19 pandemic on physicians varies on the basis of professional characteristics and experiences. Physicians remain at increased risk for burnout relative to workers in other fields.

Suicidal Ideation and Attitudes Regarding Help Seeking in US Physicians Relative to the US Working Population.

OBJECTIVE: To evaluate the prevalence of suicidal ideation (SI) and attitudes regarding help seeking among US physicians relative to the general US working population. PARTICIPANTS AND METHODS: A secondary analysis of a cross-sectional survey of US physicians and a probability-based sample of the US working population was conducted between October 12, 2017, and March 15, 2018. Among 30,456 invited physicians, 5197 (17.1%) completed the primary survey. Suicidal ideation in the last year, attitudes regarding help seeking, symptoms of depression, and burnout were assessed by standardized questions. RESULTS: Among the 4833 physicians who responded regarding SI, 316 (6.5%) reported having suicidal thoughts in the last 12 months. Most physicians (3527 [72.9%]) reported that they would seek professional help if they had a serious emotional problem. Physicians with SI were less likely to report that they would seek help (203/316 [64.2%]) than physicians without SI (3318/4517 [73.5%]; P=.001). On multivariable analysis, symptoms of depression (odds ratio [OR], 4.42; 95% CI, 1.89 to 11.52), emotional exhaustion (OR, 1.07 each 1-point increase; 95% CI, 1.03 to 1.11), and self-valuation (OR, 0.84 each 1-point increase; 95% CI, 0.70 to 0.99) were associated with SI. Among individuals aged 29 to 65 years, physicians were more likely than workers in other fields to report SI (7.1% vs 4.3%; P<.001), a finding that persisted on multivariable analysis. CONCLUSION: In this national study conducted before the COVID-19 pandemic, 1 in 15 US physicians had thoughts of taking their own life in the last year, which exceeded the prevalence of SI among US workers in other fields.

Physician Task Load and the Risk of Burnout Among US Physicians in a National Survey.

BACKGROUND: Cognitive task load can affect providers' ability to perform their job well and may contribute to burnout. METHODS: The researchers evaluated whether task load, measured by the National Aeronautics and Space Administration (NASA) Task Load Index (TLX), correlated with burnout scores in a large national study of US physicians between October 2017 and March 2018 with a 17.1% response rate. Burnout was measured using the Emotional Exhaustion and Depersonalization scales of the Maslach Burnout Inventory, and a high score on either score was considered a manifestation of professional burnout. The NASA-TLX was chosen to evaluate physician task load (PTL) due to its robust validation and use across many industries, including health care, over the past 30 years. The domains included in the PTL were mental, physical, and temporal demands, and perception of effort. RESULTS: Mean score in task load dimension varied by specialty. In aggregate, high emotional exhaustion, depersonalization, and one symptom of burnout was seen in 38.8%, 27.4%, and 44.0% of participants, respectively. The mean PTL score was 260.9/400 (standard deviation = 71.4). The specialties with the highest PTL score were emergency medicine, urology, anesthesiology, general surgery subspecialties, radiology, and internal medicine subspecialties. A dose response relationship between PTL and burnout was observed. For every 40-point (10%) decrease in PTL there was 33% lower odds of experiencing burnout (odds ratio = 0.67, 95% confidence interval = 0.65-0.70, p < 0.0001). CONCLUSION: The relationship between PTL and burnout may suggest areas of particular focus to improve the practice environment and reduce physician burnout.

Burnout and satisfaction with work-life integration among PAs relative to other workers.

OBJECTIVE: To evaluate burnout and satisfaction with work-life integration among physician assistants (PAs) compared with other US workers. METHODS: We surveyed PAs and a probability-based sample of US workers. The survey included the Maslach Burnout Inventory and an item on satisfaction with work-life integration. RESULTS: Overall, 41.4% of PAs had burnout symptoms and 65.3% were satisfied with their work-life integration. In multivariable analysis, working in emergency medicine and dissatisfaction with control of workload and work-life integration were independently associated with having higher odds of burnout. PAs were more likely to have burnout than other workers but did not have greater struggles with work-life integration. CONCLUSION: Findings from this study suggest burnout and dissatisfaction with work-life integration are common. PAs appear at higher risk for burnout than workers in other fields.

Changes in Burnout and Satisfaction With Work-Life Integration in Physicians and the General US Working Population Between 2011 and 2017.

OBJECTIVE: To evaluate the prevalence of burnout and satisfaction with work-life integration among physicians and other US workers in 2017 compared with 2011 and 2014. PARTICIPANTS AND METHODS: Between October 12, 2017, and March 15, 2018, we surveyed US physicians and a probability-based sample of the US working population using methods similar to our 2011 and 2014 studies. A secondary survey with intensive follow-up was conducted in a sample of nonresponders to evaluate response bias. Burnout and work-life integration were measured using standard tools. RESULTS: Of 30,456 physicians who received an invitation to participate, 5197 (17.1%) completed surveys. Among the 476 physicians in the secondary survey of nonresponders, 248 (52.1%) responded. A comparison of responders in the 2 surveys revealed no significant differences in burnout scores (P=.66), suggesting that participants were representative of US physicians. When assessed using the Maslach Burnout Inventory, 43.9% (2147 of 4893) of the physicians who completed the MBI reported at least one symptom of burnout in 2017 compared with 54.4% (3680 of 6767) in 2014 (P<.001) and 45.5% (3310 of 7227) in 2011 (P=.04). Satisfaction with work-life integration was more favorable in 2017 (42.7% [2056 of 4809]) than in 2014 (40.9% [2718 of 6651]; P<.001) but less favorable than in 2011 (48.5% [3512 of 7244]; P<.001). On multivariate analysis adjusting for age, sex, relationship status, and hours worked per week, physicians were at increased risk for burnout (odds ratio, 1.39; 95% CI, 1.26-1.54; P<.001) and were less likely to be satisfied with work-life integration (odds ratio, 0.77; 95% CI, 0.70-0.85; P<.001) than other working US adults. CONCLUSION: Burnout and satisfaction with work-life integration among US physicians improved between 2014 and 2017, with burnout currently near 2011 levels. Physicians remain at increased risk for burnout relative to workers in other fields.

Professional Satisfaction and the Career Plans of US Physicians.

OBJECTIVE: To evaluate the relationship between burnout, satisfaction with electronic health records and work-life integration, and the career plans of US physicians. PARTICIPANTS AND METHODS: Physicians across all specialties in the United States were surveyed between August 28, 2014, and October 6, 2014. Physicians provided information regarding the likelihood of reducing clinical hours in the next 12 months and the likelihood of leaving current practice within the next 24 months. RESULTS: Of 35,922 physicians contacted, 6880 (19.2%) returned surveys. Of the 6695 physicians in clinical practice at the time of the survey (97.3%), 1275 of the 6452 who responded (19.8%) reported it was likely or definite that they would reduce clinical work hours in the next 12 months, and 1726 of the 6496 who responded (26.6%) indicated it was likely or definite that they would leave their current practice in the next 2 years. Of the latter group, 126 (1.9% of the 6695 physicians in clinical practice at the time of the survey) indicated that they planned to leave practice altogether and pursue a different career. Burnout (odds ratio [OR], 1.81; 95% CI, 1.49-2.19; P<.001), dissatisfaction with work-life integration (OR, 1.65; 95% CI, 1.27-2.14; P<.001), and dissatisfaction with the electronic health record (OR, 1.44; 95% CI, 1.16-1.80; P=.001) were independent predictors of intent to reduce clinical work hours and leave current practice. CONCLUSION: Nearly 1 in 5 US physicians intend to reduce clinical work hours in the next year, and roughly 1 in 50 intend to leave medicine altogether in the next 2 years to pursue a different career. If physicians follow through on these intentions, it could profoundly worsen the projected shortage of US physicians.

Parental satisfaction of U.S. physicians: associated factors and comparison with the general U.S. working population.

BACKGROUND: Physicians work considerably longer hours and are less satisfied with work-life balance than U.S. workers in other fields. There is, however, minimal data on physicians' parental satisfaction. METHODS: To evaluate differences in parental satisfaction among physicians and workers in other fields, we surveyed U.S. physicians as well as a probability-based sample of the general U.S. working population between August 2014-October 2014. Parental satisfaction and the perceived impact of career on relationships with children were evaluated. RESULTS: Among 6880 responding physicians (cooperation rate 19.2 %), 5582 (81.1 %) had children. Overall, physicians were satisfied in their relationships with their children, with 4782 (85.9 %) indicating that they were either very satisfied [n = 2738; (49.2 %)] or satisfied [n = 2044 (36.7 %)]. In contrast, less than half believed their career had made either a major [n = 1212; (21.8 %)] or minor positive [n = 1260; (22.7 %)] impact on their relationship with their children, with a slightly larger proportion indicating a major (n = 2071 [37.2 %]) or minor (n = 501 [9 %]) negative impact. Women physicians were less likely to believe their career had made a positive impact as were younger physicians. Hours worked/week inversely correlated with the belief that career had made a positive impact on relationships with children. Both men (OR: 2.75; p < 0.0001) and women (OR: 4.33; p < 0.0001) physicians were significantly more likely to report that their career had a negative impact on relationships with their children than the sex-matched U.S. working population. CONCLUSIONS: U.S. physicians report generally high satisfaction in their relationships with their children. Despite their high satisfaction, physicians have a more negative perception of the impact of their career on relationships with their children than U.S. workers in general.

Relationship Between Clerical Burden and Characteristics of the Electronic Environment With Physician Burnout and Professional Satisfaction.

OBJECTIVE: To evaluate associations between the electronic environment, clerical burden, and burnout in US physicians. PARTICIPANTS AND METHODS: Physicians across all specialties in the United States were surveyed between August and October 2014. Physicians provided information regarding use of electronic health records (EHRs), computerized physician order entry (CPOE), and electronic patient portals. Burnout was measured using validated metrics. RESULTS: Of 6375 responding physicians in active practice, 5389 (84.5%) reported that they used EHRs. Of 5892 physicians who indicated that CPOE was relevant to their specialty, 4858 (82.5%) reported using CPOE. Physicians who used EHRs and CPOE had lower satisfaction with the amount of time spent on clerical tasks and higher rates of burnout on univariate analysis. On multivariable analysis, physicians who used EHRs (odds ratio [OR]=0.67; 95% CI, 0.57-0.79; P<.001) or CPOE (OR=0.72; 95% CI, 0.62-0.84; P<.001) were less likely to be satisfied with the amount of time spent on clerical tasks after adjusting for age, sex, specialty, practice setting, and hours worked per week. Use of CPOE was also associated with a higher risk of burnout after adjusting for these same factors (OR=1.29; 95% CI, 1.12-1.48; P<.001). Use of EHRs was not associated with burnout in adjusted models controlling for CPOE and other factors. CONCLUSION: In this large national study, physicians' satisfaction with their EHRs and CPOE was generally low. Physicians who used EHRs and CPOE were less satisfied with the amount of time spent on clerical tasks and were at higher risk for professional burnout.

Changes in Burnout and Satisfaction With Work-Life Balance in Physicians and the General US Working Population Between 2011 and 2014.

OBJECTIVE: To evaluate the prevalence of burnout and satisfaction with work-life balance in physicians and US workers in 2014 relative to 2011. PATIENTS AND METHODS: From August 28, 2014, to October 6, 2014, we surveyed both US physicians and a probability-based sample of the general US population using the methods and measures used in our 2011 study. Burnout was measured using validated metrics, and satisfaction with work-life balance was assessed using standard tools. RESULTS: Of the 35,922 physicians who received an invitation to participate, 6880 (19.2%) completed surveys. When assessed using the Maslach Burnout Inventory, 54.4% (n=3680) of the physicians reported at least 1 symptom of burnout in 2014 compared with 45.5% (n=3310) in 2011 (P<.001). Satisfaction with work-life balance also declined in physicians between 2011 and 2014 (48.5% vs 40.9%; P<.001). Substantial differences in rates of burnout and satisfaction with work-life balance were observed by specialty. In contrast to the trends in physicians, minimal changes in burnout or satisfaction with work-life balance were observed between 2011 and 2014 in probability-based samples of working US adults, resulting in an increasing disparity in burnout and satisfaction with work-life balance in physicians relative to the general US working population. After pooled multivariate analysis adjusting for age, sex, relationship status, and hours worked per week, physicians remained at an increased risk of burnout (odds ratio, 1.97; 95% CI, 1.80-2.16; P<.001) and were less likely to be satisfied with work-life balance (odds ratio, 0.68; 95% CI, 0.62-0.75; P<.001). CONCLUSION: Burnout and satisfaction with work-life balance in US physicians worsened from 2011 to 2014. More than half of US physicians are now experiencing professional burnout.

The prevalence of substance use disorders in American physicians.

BACKGROUND: There have been few studies on the prevalence of substance use disorders (SUDS) in the physician population at large nor have any studies compared the prevalence of SUDS in American physicians by specialty. METHODS: We conducted a national study of SUDS in a large sample of U.S. physicians from all specialty disciplines using the AMA Physician Masterfile. Substance Use Disorders (SUDS) were measured using validated instruments. RESULTS: Of the 27,276 physicians who received an invitation to participate, 7,288 (26.7%) completed surveys. 12.9% of male physicians and 21.4% of female physicians met diagnostic criteria for alcohol abuse or dependence. Abuse of prescription drugs and use of illicit drugs was rare. Factors independently associated with alcohol abuse or dependence were age (OR = .985; p < .0001), hours worked (OR = .994; p = .0094), male gender (OR = .597; p < .0001), being married (OR 1.296; p = .0424) or partnered (OR 1.989; p = .0003), having children (OR .745; p = .0049), and being in any specialty other than internal medicine (OR 1.757; p = .0060). Specialty choice was strongly associated with alcohol abuse or dependence (p = .0011). Alcohol abuse or dependence was associated with burnout (p < .0001), depression (p < .0001), suicidal ideation (p = .0004), lower quality of life (p < .0001), lower career satisfaction (p = .0036), and recent medical errors (p = .0011). CONCLUSION: Alcohol abuse or dependence is a significant problem among American physicians. Since prognosis for recovery of physicians from chemical dependency is exceptionally high, organizational approaches for the early identification of problematic alcohol consumption in physicians followed by intervention and treatment where indicated should be strongly supported.

An interactive individualized intervention to promote behavioral change to increase personal well-being in US surgeons.

OBJECTIVE: Evaluate the utility of a computer-based, interactive, and individualized intervention for promoting well-being in US surgeons. BACKGROUND: Distress and burnout are common among US surgeons. Surgeons experiencing distress are unlikely to seek help on their own initiative. A belief that distress and burnout are a normal part of being a physician and lack of awareness of distress level relative to colleagues may contribute to this problem. METHODS: Surgeons who were members of the American College of Surgeons were invited to participate in an intervention study. Participating surgeons completed a 3-step, interactive, electronic intervention. First, surgeons subjectively assessed their well-being relative to colleagues. Second, surgeons completed the 7-item Mayo Clinic Physician Well-Being Index and received objective, individualized feedback about their well-being relative to national physician norms. Third, surgeons evaluated the usefulness of the feedback and whether they intended to make specific changes as a result. RESULTS: A total of 1150 US surgeons volunteered to participate in the study. Surgeons' subjective assessment of their well-being relative to colleagues was poor. A majority of surgeons (89.2%) believed that their well-being was at or above average, including 70.5% with scores in the bottom 30% relative to national norms. After receiving objective, individualized feedback based on the Mayo Clinic Physician Well-Being Index score, 46.6% of surgeons indicated that they intended to make specific changes as a result. Surgeons with lower well-being scores were more likely to make changes in each dimension assessed (all Ps<0.001). CONCLUSIONS: US surgeons do not reliably calibrate their level of distress. After self-assessment and individualized feedback using the Mayo Clinic Physician Well-Being Index, half of participating surgeons reported that they were contemplating behavioral changes to improve personal well-being.

The medical marriage: a national survey of the spouses/partners of US physicians.

OBJECTIVE: To evaluate physician relationships from the perspective of their spouses/partners. METHODS: Nearly all data on satisfaction with physician relationships come from the perspective of the physician rather than their spouse/partner. We conducted a national study of the spouses/partners of US physicians from August 17, 2011, through September 12, 2011. Responding spouses/partners provided information on demographic characteristics, their own work life, and the work life of their physician partners. Spouses/partners also rated relationship satisfaction and the effect of the work life of their physician partner on the relationship. RESULTS: Of the 1644 spouses/partners of physicians surveyed, 891 (54.2%) responded. Most spouses/partners (86.8%) reported that they were satisfied with their relationship with their physician partner. Satisfaction strongly related to the amount of time spent awake with their physician partners each day. Despite their overall satisfaction, spouses/partners reported their physician partners frequently came home irritable, too tired to engage in home activities, or preoccupied with work. On multivariate analysis, minutes spent awake with their physician partners each day was the strongest predictor of relationship satisfaction, exhibiting a dose-response effect. No professional characteristic of the physician partners (eg, hours worked per week, specialty area, and practice setting) other than the number of nights on call per week correlated with relationship satisfaction on adjusted analysis. CONCLUSION: The spouses/partners of US physicians report generally high satisfaction with their relationships. The mean time spent with their physician partners each day appears to be a dominant factor associated with relationship satisfaction and overshadows any specific professional characteristic of the physicians' practice, including specialty area, practice setting, and work hours.
