The difficult doctor? Characteristics of physicians who report frustration with patients: an analysis of survey data.

BACKGROUND: Literature on difficult doctor-patient relationships has focused on the "difficult patient." Our objective was to determine physician and practice characteristics associated with greater physician-reported frustration with patients. METHODS: We conducted a secondary analysis of the Physicians Worklife Survey, which surveyed a random national sample of physicians. Participants were 1391 family medicine, general internal medicine, and medicine subspecialty physicians. The survey assessed physician and practice characteristics, including stress, depression and anxiety symptoms, practice setting, work hours, case-mix, and control over administrative and clinical practice. Physicians estimated the percentage of their patients who were "generally frustrating to deal with." We categorized physicians by quartile of reported frustrating patients and compared characteristics of physicians in the top quartile to those in the other three quartiles. We used logistic regression to model physician characteristics associated with greater frustration. RESULTS: In unadjusted analyses, physicians who reported high frustration with patients were younger (p < 0.001); worked more hours per week (p = 0.041); and had more symptoms of depression, stress, and anxiety (p < 0.004 for all). In the final model, factors independently associated with high frustration included age < 40 years, work hours > 55 per week, higher stress, practice in a medicine subspeciality, and greater number of patients with psychosocial problems or substance abuse. CONCLUSION: Personal and practice characteristics of physicians who report high frustration with patients differ from those of other physicians. Understanding factors contributing to physician frustration with patients may allow us to improve the quality of patient-physician relationships.

Surrogates' perceptions about feeding tube placement decisions.

OBJECTIVES: (1) To determine surrogates perceptions about who made the decision to place the feeding tube and who they would have preferred to have made the decision. (2) To determine surrogates' perceptions of the information they received to make this decision. METHODS: Structured interviews with 246 surrogate decision-makers. RESULTS: Fifty-five percent of surrogates felt that the decision was made primarily by the surrogate, but 75% would prefer that the decision be shared with the physician. Surrogates reported that they discussed the benefits (80%) and the risks (72%) of feeding tube placement and discussed what life would be like with the feeding tube (65%) and without the feeding tube (67%). They also reported being asked if they understood the information (85%) and their thoughts about placement (56%). Despite receiving this information, 28 to 41% reported wanting more information about these aspects. CONCLUSION: Surrogates would have preferred greater physician participation in decisions about feeding tube placement and many reported that their informational needs were not completely met. PRACTICE IMPLICATIONS: These results suggest that physicians may be justified in taking a more active role in feeding tube decisions with surrogates and that many surrogates desire more information than is required by standards of informed decision making.

Effects of sex, age, and visits on receipt of preventive healthcare services: a secondary analysis of national data.

BACKGROUND: Sex and age may exert a combined influence on receipt of preventive services with differences due to number of ambulatory care visits. METHODS: We used nationally representative data to determine weighted percentages and adjusted odds ratios of men and women stratified by age group who received selected preventive services. The presence of interaction between sex and age group was tested using adjusted models and retested after adding number of visits. RESULTS: Men were less likely than women to have received blood pressure screening (aOR 0.44;0.40-0.50), cholesterol screening (aOR 0.72;0.65-0.79), tobacco cessation counseling (aOR 0.66;0.55-0.78), and checkups (aOR 0.53;0.49-0.57). In younger age groups, men were particularly less likely than women to have received these services. In adjusted models, this observed interaction between sex and age group persisted only for blood pressure measurement (p = .016) and routine checkups (p < .001). When adjusting for number of visits, the interaction of age on receipt of blood pressure checks was mitigated but men were still overall less likely to receive the service. CONCLUSION: Men are significantly less likely than women to receive certain preventive services, and younger men even more so. Some of this discrepancy is secondary to a difference in number of ambulatory care visits.

Expectations and outcomes of gastric feeding tubes.

PURPOSE: To compare expected outcomes with actual outcomes from tube feeding in adult patients. SUBJECTS AND METHODS: This prospective cohort study was conducted in two North Carolina hospitals. Surrogates were interviewed shortly after feeding tube insertion and at 3- and 6-month follow-up; chart abstraction and death certificate review also were carried out. Participants were surrogate decision-makers for consecutive adult patients who received new feeding tubes. RESULTS: There were 288 patients with surrogate decision-makers enrolled. Mean age was 65 years; 30% had a primary diagnosis of stroke, 16% neurodegenerative disorder, 20% head and neck cancer, and 30% other diagnoses. At 3 months, 21% of patients had died, and 6-month mortality was 30%. At 3 months, 38% of survivors were residing in a nursing home, and 27% had the feeding tube removed. Patients were impaired in most activities of daily living (ADLs) with little change over time. Medical complications were common: 25% of patients had decubitus ulcers at 3 months, and 24% had at least one episode of pneumonia. Perceived global quality of life was poor at 4.6 (on a 0-10 scale) at baseline, and surrogates anticipated this would improve to 8.0 with tube feeding. Family surrogates' expectations for improvement from the feeding tube were very high at baseline and remained so at 3 and 6 months. CONCLUSIONS: Families' high expectations of benefit from tube feeding are in contrast to clinical outcomes. Providers and families need better information about the outcomes of this common procedure.

The epidemiology of threatened preterm labor: a prospective cohort study.

OBJECTIVE: The purpose of this study was to describe the occurrence, timing, and outcomes of hospital-based diagnoses of preterm labor. STUDY DESIGN: Administrative records identified hospital admissions for preterm labor among 2534 women in an ongoing cohort study. Factors that were considered risks for prematurity were examined by logistic regression for an association with any preterm labor diagnosis, a preterm labor diagnosis <33 weeks of gestation, or > or =33 weeks of gestation. RESULTS: Of 234 women (9%) who experienced hospitalization for preterm labor, 90 women (38%) were delivered in the first episode. Previous preterm birth consistently was associated with a diagnosis of preterm labor. Reporting a sexually transmitted infection (odds ratio, 1.8; 95% CI, 1.1-3.0) or bacterial vaginosis (odds ratio, 2.6; 95% CI, 1.7-4.1) early in pregnancy was associated with hospitalization for preterm labor between 24 and 32 weeks of gestation. CONCLUSION: The incidence of first-time hospitalization for preterm labor was 9%, with most episodes not resulting in preterm birth. Previous preterm birth was associated therefore with a preterm labor diagnosis.

Understanding interobserver agreement: the kappa statistic.

Items such as physical exam findings, radiographic interpretations, or other diagnostic tests often rely on some degree of subjective interpretation by observers. Studies that measure the agreement between two or more observers should include a statistic that takes into account the fact that observers will sometimes agree or disagree simply by chance. The kappa statistic (or kappa coefficient) is the most commonly used statistic for this purpose. A kappa of 1 indicates perfect agreement, whereas a kappa of 0 indicates agreement equivalent to chance. A limitation of kappa is that it is affected by the prevalence of the finding under observation. Methods to overcome this limitation have been described.

Performance of osteoporosis risk assessment tools in postmenopausal women aged 45-64 years.

Osteoporosis risk factor assessment is of uncertain utility in women under 65 years of age. Previous comparative studies of osteoporosis risk assessment tools were not stratified by age. We compared the discriminatory ability of three previously validated osteoporosis risk assessment tools in a referral population of postmenopausal women aged 45-64 years (n=2539) and aged 65-96 years (n=1496) seen at a university-based outpatient osteoporosis center in Belgium. Risk scores for the Osteoporosis Self-assessment Tool, Osteoporosis Risk Assessment Instrument, and Simple Calculated Osteoporosis Risk Estimation were calculated for each patient. The reference standard was osteoporosis at the femoral neck, defined as a T-score < or =-2.5 based on bone mineral density measured by dual energy X-ray absorptiometry. Osteoporosis was present in 139 of 2539 (5.5%) women aged 45-64 years and 241 of 1496 (16.1%) women aged 65 years or older. The tools had similar overall discriminatory ability to identify women with osteoporosis [area under the ROC curve 0.750-0.768, P=0.23 for women aged 45-64 years; area under the ROC curve 0.745-0.762, P=0.06 for women aged 65 years or older (P>0.05 indicates no difference among tools)]. The likelihood ratios for the high-risk score categories ranged from 3.60 to 6.73 for the younger women and 3.45 to 6.99 for the older women when different score thresholds were set to maximize the performance of each tool in each age group. We conclude that the diagnostic accuracy of three osteoporosis risk assessment tools was similar in postmenopausal women aged 45-64 years and women aged 65 years or older. Use of structured risk assessment tools to identify women at high risk of osteoporosis in the early postmenopausal period warrants further study. Of the three tools evaluated, the OST is the simplest and has the best potential for use in clinical practice.

Stability of risk-adjusted primary cesarean delivery rates over time.

OBJECTIVE: The purpose of this study was to compare how hospital rankings, based on risk-adjusted primary cesarean rates, change over time. STUDY DESIGN: Washington State Birth Events records data from 1995 through 1998 were used. Risk-adjustment models were built for each year. Risk-adjusted hospital rankings and outlier status (either "above" or "below" expected cesarean delivery rates) were calculated for each year. Hospitals that were identified as outliers for each year were compared with the use of kappa statistics. The top and bottom 25% of the hospital rank list from each year were also compared. RESULTS: The overall kappa statistic that compared outlier status over the 4 years was 0.44. The kappa statistic for the upper 25% of rankings over the 4 years was 0.42. The kappa statistic for the lowest 25% of rankings over the 4 years was 0.57. CONCLUSION: Although exact ranking may not be meaningful, outlier status, especially if repeated in multiple years may be a good marker for the identification of hospitals for further scrutiny of their quality of care.

Trends in the use of feeding tubes in North Carolina hospitals.

OBJECTIVE: National data describing the placement of feeding tubes demonstrated a rapid increase in use in the early and mid-1990s. In the past several years, substantial concerns have arisen regarding the appropriateness of the procedure in many chronically ill patients. The purpose of this study is to determine whether the use of feeding tubes has continued to increase through the 1990s despite these widely publicized concerns. DESIGN: Repeated measure cross-sectional study of the North Carolina Discharge Database. SETTING: Analyses of all nonfederal hospital inpatient admissions in North Carolina. MEASUREMENTS AND MAIN RESULTS: We examined the absolute numbers and rates of feeding tube placements from 1989 to 2000. The rate of feeding tube placement increased from 59/100,000 persons in 1989 to 94/100,000 persons in 2000, an overall 60% increase with slowing in the rate of increase in the late 1990s. However, when outpatient procedures were included, the increase in tube feeding continued throughout the 11-year period of observation. The increase was due to an increase in utilization within all hospitals over the time period. Utilization did not differ between profit and not for profit hospitals. The relative growth rate of inpatient feeding tube placement did not differ by age group but the absolute increase was greatest in those age 75 years and over. CONCLUSIONS: Our study demonstrates that the use of feeding tubes has continued to increase through the 1990s. This increase occurred despite ongoing controversy in the medical literature about feeding tube placement in chronically ill patients.

Self-reported delay in seeking care has poor validity for predicting adverse outcomes.

OBJECTIVES: To determine whether self-reports of delayed care predict increased mortality and functional decline in community-dwelling elderly. DESIGN: Longitudinal cohort study. SETTING: Five counties in North Carolina. PARTICIPANTS: A total of 4,162 randomly sampled individuals aged 65 and older. MEASUREMENTS: The primary outcome was the proportional hazard ratio (HR) for death in cohorts stratified by self-reports of delayed or foregone care. A secondary outcome, functional decline, measured the cohorts' odds of developing increased dependency in activities of daily living (ADLs). Control variables included predisposing, enabling, and need factors. RESULTS: Of 3,964 eligible participants reporting, 61% never, 27% once in a while, and 12% quite often delayed care. Over 3 years, 13% of participants died, and 17% developed increased ADL dependency. Nevertheless, in unadjusted and adjusted models, neither 3-year mortality HRs nor the odds of functional decline differed between cohorts reporting varying degrees of delayed care. Survival probabilities remained higher for 15 years among those reporting delaying care often. CONCLUSION: The inability of self-reported delay to predict adverse outcomes in community-dwelling elderly suggests the need for better understanding and support of the care-seeking process and additional measures of timeliness of access.

Do osteopathic physicians differ in patient interaction from allopathic physicians? An empirically derived approach.

Colleges of osteopathic medicine teach osteopathic principles, which provide a different approach to and interaction with patients than principles taught in allopathic medical schools. The authors examined whether osteopathic primary care physicians' interactions with patients reflect the principles of osteopathic medicine when compared with allopathic physicians' interactions. The principles of osteopathic medicine were adapted to elements that could be measured from an audio recording. This 26-item index was refined with two focus groups of practicing osteopathic physicians. Fifty-four patient visits to 11 osteopathic and 7 allopathic primary care physicians in Maine for screening physicals, headache, low back pain, and hypertension were recorded on audiotape and were dual-abstracted. When the 26-item index of osteopathic principles was summed, the osteopathic physicians had consistently higher scores (11 vs. 6.9; P = .01) than allopathic physicians, and visit length was similar (22 minutes vs. 20 minutes, respectively). Twenty-three of the 26 items were used more commonly by the osteopathic physicians. Osteopathic physicians were more likely than allopathic physicians to use patients' first names; explain etiologic factors to patients; and discuss social, family, and emotional impact of illnesses. In this study, osteopathic physicians were easily distinguishable from allopathic physicians by their verbal interactions with patients. Future studies should replicate this finding as well as determine whether it correlates with patient outcomes and satisfaction.

Effectiveness of medical resident education in mechanical ventilation.

Specific methods of mechanical ventilation management reduce mortality and lower health care costs. However, in the face of a predicted deficit of intensivists, it is unclear whether residency programs are training internists to provide effective care for patients who require mechanical ventilation. To evaluate these educational outcomes, we administered a validated 19-item case-based test and survey to resident physicians at 31 diverse U.S. internal medicine residency programs nationwide. Of 347 senior residents, 259 (75%) responded. The mean test score was 74% correct (SD, 14%; range, 37 to 100%). Important items representing evidence-based standards of critical care answered incorrectly were as follows: use of appropriate tidal volume in the acute respiratory distress syndrome (48% incorrect), identifying a patient ready for a weaning trial (38% incorrect), and recognizing indication for noninvasive ventilation (27% incorrect). Most accurately identified pneumothorax (86% correct) and increased intrathoracic positive end-expiratory pressure (93% correct). Better scores were associated with "closed" versus "open" intensive care unit organization (76 versus 71% correct, p = 0.001), resident perception of greater versus lesser ventilator knowledge (79 versus 71% correct, p = 0.001), and graduation from a U.S. versus international medical school (75 versus 69% correct, p = 0.033). Although overall training satisfaction correlated strongly with program use of learning objectives (r = 0.89, p < 0.0001), only 46% reported being satisfied with their mechanical ventilation training. We conclude that senior residents may not be gaining essential evidence-based knowledge needed to provide effective care for patients who require mechanical ventilation. Residency programs should emphasize evidence-based learning objectives to guide mechanical ventilation instruction.

The natural history of the development of obesity in a cohort of young U.S. adults between 1981 and 1998.

BACKGROUND: Understanding the natural history of obesity in a population may be a critical step toward developing effective interventions. OBJECTIVE: To assess the development of body mass and examine the role of race or ethnicity, sex, and birth year in obesity onset in young U.S. adults. DESIGN: Prospective cohort study. SETTING: The National Longitudinal Survey of Youth 1979, a national sample with oversampling of minority ethnic groups. PARTICIPANTS: 9179 persons. MEASUREMENTS: Body mass index (BMI) calculated from 12 self-reported height and weight samples recorded between 1981 and 1998. Logistic regression identified predictors of obesity at age 35 to 37 years. Cox proportional hazards models compared the incidence of obesity by ethnicity and birth year. RESULTS: Overall, 26% of men and 28% of women were obese (BMI > or = 30 kg/m2) by age 35 to 37 years. Race or ethnicity and baseline BMI were significant predictors of obesity. Obesity onset was 2.1 (95% CI, 1.6 to 2.7) times faster for black women and 1.5 (CI, 1.1 to 2.0) times faster for Hispanic women than for white women. The pattern for men differed: Overall, obesity developed most rapidly in Hispanic men, but relative rates of obesity onset for white men compared with black men varied according to age. The rate of obesity onset increased 26% to 28% over an 8-year span in birth year. CONCLUSIONS: Marked ethnic-based differences were found in rates of weight accumulation in young U.S. adults, with later birth cohorts experiencing earlier onset of obesity. To alter the course of obesity in the United States, interventions should target young adults, especially those of minority ethnic groups.

Obstetrician-gynecologists and the intrauterine device: a survey of attitudes and practice.

OBJECTIVE: To assess obstetrician-gynecologists' clinical use of the intrauterine device (IUD), their attitudes toward the IUD and how they select IUD candidates, and to test the hypotheses that limited residency training in IUDs, fear of litigation, and a belief that IUDs cause pelvic inflammatory disease decrease IUD use. METHODS: We performed a national mailed survey of 811 practicing obstetrician-gynecologists obtained from systematic sampling of ACOG membership listings to assess use of and attitudes toward the IUD. RESULTS: The survey response rate was 50%. Most respondents agreed that the copper IUD is safe (95%) and effective (98%). However, 20% of respondents had not inserted an IUD in the past year, and of those who had, most (79%) reported inserting 10 or fewer. Fear of litigation and a belief that IUDs cause pelvic inflammatory disease were associated with lower IUD use; the number of IUDs inserted during residency was not. In selecting IUD candidates, respondents were most restrictive about patient monogamy. Having less conservative criteria for selecting IUD candidates was associated with greater IUD use. Respondents with liberal criteria inserted a mean of nine IUDs in the past year, whereas those with conservative criteria inserted four. CONCLUSIONS: Because most obstetrician-gynecologists are inserting few IUDs, educational programs should target these physicians to expand their IUD use. Such programs should highlight modern IUD safety and the rarity of litigation. The number of IUDs inserted in residency may be less important than the development of less restrictive, more evidence-based criteria for selecting IUD candidates.

Hospital primary cesarean delivery rates and the risk of poor neonatal outcomes.

OBJECTIVE: The purpose of this study was to determine whether risk-adjusted hospital primary cesarean delivery rates are associated with poor neonatal outcomes. STUDY DESIGN: The Washington State Birth Events Records for 1995 and 1996 were used. Predicted primary cesarean delivery rates were calculated for each hospital. Women were divided by whether the hospital had an actual primary cesarean delivery rate below, within, or greater than the predicted CI. Asphyxia (a lack of oxygen that leads to organ damage) was used as a marker of poor neonatal outcome. Risk of neonatal asphyxia was compared for each of the 3 cesarean rating groups. RESULTS: The risk for asphyxia among infants who were born to women who delivered at hospitals that had more, within, or fewer cesarean deliveries than predicted were 0.58%, 0.17%, and 0.33%, respectively (P <.0001). CONCLUSION: Infants born to women who delivered at hospitals that had more than or fewer than the predicted number of primary cesarean deliveries experienced a greater risk of neonatal asphyxia.

Adults' lack of a usual source of care: a matter of preference?

PURPOSE: We wanted to identify characteristics of adults who do not have a usual source of care and then stratify the analysis by those who prefer vs those who do not prefer to have a usual source of care. METHODS: We analyzed data from a nationally representative sample of 9,011 adults to identify characteristics of those more likely to not have a usual source of care. Based on stated reasons for lacking a usual source of care, we created 2 subpopulations of adults without a usual source of care: those who had no preference and those who did. We identified and compared characteristics of each subpopulation. RESULTS: In the year 2000, 20% of adults did not have a usual source of care. Among all adults, lack of insurance (odds ratio [OR] = 3.2; 95% confidence interval [CI], 2.6-3.9) was independently associated with lacking a usual source of care, as were male sex (OR = 2.1; 95% CI, 1.7-2.4), excellent reported health (OR = 2.0; 95% CI, 1.2-3.2), younger age (for ages 18-29 years, OR = 4.1; 95% CI, 3.1-5.4) and Hispanic ethnicity (OR = 1.5; 95% CI,1.2-1.9). Of those without a usual source of care, 72% cited reasons indicating no preference to have one. Associations among such respondents were similar to those found among adults as a whole. Among respondents who preferred to have a usual source of care, however, the sex of the respondent became less significant, lack of insurance became more significant, and reported health status became nonsignificant. CONCLUSIONS: Most adults who lack a usual source of care do so for reasons of preference, evidently placing little value on having a usual source of care. Helping these persons have a usual source of care will likely require different interventions than needed to help those who want a usual source of care but cannot get one.

Depression in assisted living: results from a four-state study.

OBJECTIVE: Assisted living is a rapidly-growing sector of long-term care, but little research has been done on depression in this setting. Using data from a large sample of assisted-living residents, the authors sought to 1) describe the prevalence of depression and depressive symptoms; 2) identify resident characteristics associated with depression; and 3) examine the relationship between depression and the rate of nursing home placement and mortality. METHODS: A group of 2,078 residents age 65 and older were enrolled from 193 assisted-living facilities across four states (Florida, Maryland, New Jersey, and North Carolina). Residents were classified as depressed if their score on the Cornell Scale for Depression in Dementia (CSDD) exceeded 7. RESULTS: Using this criterion, 13% were depressed, and only 18% of those were on antidepressants. Over one-third of residents had symptoms of depression, such as anxious expression, rumination, or worrying, and 25% displayed sad voice, sad expression, or tearfulness. Depression was significantly associated with medical comorbidity, social withdrawal, psychosis, agitation, and length of residence in the facility. Depressed residents were discharged to nursing homes at 1.5 times the rate of nondepressed residents. Rates of mortality were also higher for depressed residents, but only those with severe depression (CSDD >12) had a statistically significant increased rate of death. CONCLUSION: The mission of assisted living is to help older adults retain autonomy, privacy, and quality of life in a personalized environment. Greater effort should be made to detect and treat depression in this setting, both to reduce suffering and prolong the resident's ability to remain in their preferred environment.
