Watchful waiting as a strategy to reduce low-value spinal imaging: study protocol for a randomized trial.

BACKGROUND: Patients with acute low back pain frequently request diagnostic imaging, and clinicians feel pressure to acquiesce to such requests to sustain patient trust and satisfaction. Spinal imaging in patients with acute low back pain poses risks from diagnostic evaluation of false-positive findings, patient labeling and anxiety, and unnecessary treatment (including spinal surgery). Watchful waiting advice has been an effective strategy to reduce some low-value treatments, and some evidence suggests a watchful waiting approach would be acceptable to many patients requesting diagnostic tests. METHODS: We will use key informant interviews of clinicians and focus groups with primary care patients to refine a theory-informed standardized patient-based intervention designed to teach clinicians how to advise watchful waiting when patients request low-value spinal imaging for low back pain. We will test the effectiveness of the intervention in a randomized clinical trial. We will recruit 8-10 primary care and urgent care clinics (~ 55 clinicians) in Sacramento, CA; clinicians will be randomized 1:1 to intervention and control groups. Over a 3- to 6-month period, clinicians in the intervention group will receive 3 visits with standardized patient instructors (SPIs) portraying patients with acute back pain; SPIs will instruct clinicians in a three-step model emphasizing establishing trust, empathic communication, and negotiation of a watchful waiting approach. Control physicians will receive no intervention. The primary outcome is the post-intervention rate of spinal imaging among actual patients with acute back pain seen by the clinicians adjusted for rate of imaging during a baseline period. Secondary outcomes are use of targeted communication techniques during a follow-up visit with an SP, clinician self-reported use of watchful waiting with actual low back pain patients, post-intervention rates of diagnostic imaging for other musculoskeletal pain syndromes (to test for generalization of intervention effects beyond back pain), and patient trust and satisfaction with physicians. DISCUSSION: This trial will determine whether standardized patient instructors can help clinicians develop skill in negotiating a watchful waiting approach with patients with acute low back pain, thereby reducing rates of low-value spinal imaging. The trial will also examine the possibility that intervention effects generalize to other diagnostic tests. TRIAL REGISTRATION: ClinicalTrials.gov NCT04255199 . Registered on January 20, 2020.

Cancer Screening Among Women Prescribed Opioids: A National Study.

PURPOSE: Prior work suggests that there are competing demands between addressing pain and other issues in primary care, potentially lessening delivery of evidence-based cancer screening. We assessed the association between opioid therapy and cancer screening among women in a nationally representative US sample. METHODS: We conducted an observational analysis of the 2005-2015 Medical Expenditure Panel Surveys. We included all women aged ≥18 years without cancer and with opioid prescription and preventive care services data. Logistic regression analyses examined associations between receipt of opioid prescription (any vs none) and receipt of breast, cervical, and colorectal cancer screenings. Analyses were adjusted for sociodemographic characteristics, health status, health conditions, and usual source of care, as well as health care utilization. RESULTS: Of 53,982 participants, 15.8% reported ≥1 opioid prescription. Compared with women not prescribed opioids, those prescribed opioids were more likely to visit their doctor (median number of visits per year = 5, vs 1). Without adjustment for number of visits, women prescribed opioids were more likely to receive all 3 cancer screenings; the adjusted odds ratio for breast cancer screening was 1.26 (95% CI, 1.16-1.38), that for cervical cancer screening was 1.22 (95% CI, 1.13-1.33), and that for colorectal cancer screening was 1.22 (95% CI, 1.12-1.33). With adjustment for number of visits, adjusted odds ratios decreased (breast 1.07 [95% CI, 0.98-1.18]; cervical 1.01 [95% CI, 0.93-1.09]; colorectal 1.04 [95% CI, 0.95-1.14]). CONCLUSIONS: In a nationally representative sample, receipt of opioid prescriptions was not associated with less recommended cancer screenings. Rather, women receiving opioids had greater adjusted odds of receiving breast, cervical, and colorectal cancer screening, although the associations were attenuated by adjusting for their more frequent office visits relative to women not receiving opioids.

Patient Satisfaction with Clinicians and Short-Term Mortality in a US National Sample: the Roles of Morbidity and Gender.

BACKGROUND: In a prior study, we found patient satisfaction was associated with mortality. However, that study included few deaths, yielding wide confidence intervals, was criticized for possible morbidity under-adjustment, and lacked power to explore sociodemographic moderation. OBJECTIVE: To revisit the satisfaction-mortality association in a larger national sample, allowing more precise risk estimates, sequential morbidity adjustment, and exploration of sociodemographic moderation. DESIGN: Prospective cohort study. PARTICIPANTS: 2000-2015 Adult Medical Expenditures Panel Surveys (MEPS) respondents (N = 92,952), each enrolled for 2 consecutive years. MAIN MEASURES: We used five Consumer Assessment of Health Plans Survey (CAHPS) items to assess patients' year 1 satisfaction with their clinicians. Death during the 2 years of MEPS participation was determined by proxy report. We modeled the satisfaction-mortality association in sequential regressions: model 1 included sociodemographics, model 2 added health status (approximating recommended CAHPS adjustment), and model 3 added smoking status, disease burden, and healthcare utilization. KEY RESULTS: Satisfaction was not associated with mortality in model 1. In model 2, higher satisfaction was associated with higher mortality (hazard ratios [95% CIs] for 2nd, 3rd, and 4th (top) quartiles vs. 1st quartile: 1.28 (1.01, 1.62), P = 0.04; 1.43 (1.12, 1.82), P = 0.004; and 1.57 (1.25, 1.98), P < 0.001, respectively). The associations were not attenuated in model 3. There was a significant interaction between gender and satisfaction (F[3, 443] = 3.62, P = 0.01). The association between satisfaction and mortality was significant in women only, such that their mortality advantage over men was eliminated in the highest satisfaction quartile. CONCLUSIONS: The association of higher patient satisfaction with clinicians with higher short-term mortality was evident only after CAHPS-recommended adjustment, was not attenuated by further morbidity adjustment, and was evident in women but not men. The findings suggest that characteristics among women who are more satisfied with their clinicians may be associated with increased mortality risk.

Taxonomy for colorectal cancer screening promotion: Lessons from recent randomized controlled trials.

OBJECTIVE: To derive a taxonomy for colorectal cancer screening that advances Randomized Controlled Trials (RCTs) and screening uptake. DESIGN: Detailed publication review, multiple interviews with principal investigators (PIs) and collaboration with PIs as co-authors produced a CRCS intervention taxonomy. Semi-structured interview questions with PIs (Drs. Inadomi, Myers, Green, Gupta, Jerant and Ritvo) yielded details about trial conduct. Interview comparisons led to an iterative process informing serial interviews until a consensus was obtained on final taxonomy structure. RESULTS: These taxonomy headings (Engagement Sponsor, Population Targeted, Alternative Screening Tests, Delivery Methods, and Support for Test Performance (EPADS)) were used to compare studies. Exemplary insights emphasized: 1) direct test delivery to patients; 2) linguistic-ethnic matching of staff to minority subjects; and 3) authorization of navigators to schedule or refer for colonoscopies and/or distribute stool blood tests during screening promotion. CONCLUSION: PIs of key RCTs (2012-2015) derived a CRCS taxonomy useful in detailed examination of CRCS promotion and design of future RCTs.

Does patient time spent viewing computer-tailored colorectal cancer screening materials predict patient-reported discussion of screening with providers?

The main aim is to examine whether patients' viewing time on information about colorectal cancer (CRC) screening before a primary care physician (PCP) visit is associated with discussion of screening options during the visit. We analyzed data from a multi-center randomized controlled trial of a tailored interactive multimedia computer program (IMCP) to activate patients to undergo CRC screening, deployed in primary care offices immediately before a visit. We employed usage time information stored in the IMCP to examine the association of patient time spent using the program with patient-reported discussion of screening during the visit, adjusting for previous CRC screening recommendation and reading speed.On average, patients spent 33 minutes on the program. In adjusted analyses, 30 minutes spent using the program was associated with a 41% increase in the odds of the patient having a discussion with their PCP (1.04, 1.59, 95% CI). In a separate analysis of the tailoring modules; the modules encouraging adherence to the tailored screening recommendation and discussion with the patient's PCP yielded significant results. Other predictors of screening discussion included better self-reported physical health and increased patient activation. Time spent on the program predicted greater patient-physician discussion of screening during a linked visit.Usage time information gathered automatically by IMCPs offers promise for objectively assessing patient engagement around a topic and predicting likelihood of discussion between patients and their clinician.

Watchful Waiting Strategy May Reduce Low-Value Diagnostic Testing.

BACKGROUND: PCPs need effective communication strategies to address patient requests for low-value testing while sustaining patient-provider partnerships. Watchful waiting - allowing a negotiated period of time to pass before making a firm testing decision - shows promise as a tool for addressing patient requests for low-value testing. METHODS: Observational analysis of data from a randomized controlled trial of a communication intervention designed to boost patient-centeredness and reduce low-value test ordering among 61 resident primary care physicians. Intervention effectiveness was assessed during follow-up encounters of unannounced standardized patients (SPs) who requested low-value tests. We examined associations between five physician counseling behaviors and overall patient-centeredness (Measure of Patient-Centered Communication) and requested test ordering. RESULTS: During 155 SP encounters, residents most commonly used reassurance (96% of encounters), evidence-based recommendations (97%), and watchful waiting (68 %). Resident advice to pursue watchful waiting was associated with 39% lower likelihood of test ordering (adjusted marginal effect of -38.6% [95% CI -43.6 to -33.6]). When all communication behaviors were examined together, only watchful waiting was significantly associated with test ordering (marginal effect of -38% [95% CI -44.3% to -31.7%]). Overall patient-centeredness was not associated with low-value testing. CONCLUSION: Resident physician counseling to pursue watchful waiting was associated with less ordering of requested low-value diagnostic tests, while overall patient-centeredness was not.

Promoting Patient-Centered Counseling to Reduce Use of Low-Value Diagnostic Tests: A Randomized Clinical Trial.

IMPORTANCE: Low-value diagnostic tests have been included on primary care specialty societies' "Choosing Wisely" Top Five lists. OBJECTIVE: To evaluate the effectiveness of a standardized patient (SP)-based intervention designed to enhance primary care physician (PCP) patient-centeredness and skill in handling patient requests for low-value diagnostic tests. DESIGN, SETTING, AND PARTICIPANTS: Randomized clinical trial of 61 general internal medicine or family medicine residents at 2 residency-affiliated primary care clinics at an academic medical center in California. INTERVENTIONS: Two simulated visits with SP instructors portraying patients requesting inappropriate spinal magnetic resonance imaging for low back pain or screening dual-energy x-ray absorptiometry. The SP instructors provided personalized feedback to residents regarding use of 6 patient-centered techniques to address patient concerns without ordering low-value tests. Control group physicians received SP visits without feedback and were emailed relevant clinical guidelines. MAIN OUTCOMES AND MEASURES: The primary outcome was whether resident PCPs ordered SP-requested low-value tests during up to 3 unannounced SP clinic visits over 3 to 12 months follow-up, with patients requesting spinal magnetic resonance imaging, screening dual-energy x-ray absorptiometry, or headache neuroimaging. Secondary outcomes included PCP patient-centeredness and use of targeted techniques (both coded from visit audiorecordings), and SP satisfaction with the visit (0-10 scale). RESULTS: Of 61 randomized resident PCPs (31 control group and 30 intervention group), 59 had encounters with 155 SPs during follow-up. Compared with control PCPs, intervention PCPs had similar patient-centeredness (Measure of Patient-Centered Communication, 43.9 [95% CI, 42.0 to 45.7] vs 43.7 [95% CI, 41.8 to 45.6], adjusted mean difference, -0.2 [95% CI, -2.9 to 2.5]; P = .90) and used a similar number of targeted techniques (5.4 [95% CI, 4.9 to 5.8] vs 5.4 [95% CI, 4.9 to 5.8] on a 0-9 scale, adjusted mean difference, 0 [95% CI, -0.7 to 0.6]; P = .96). Residents ordered low-value tests in 41 SP encounters (26.5% [95% CI, 19.7%-34.1%]) with no significant difference in the odds of test ordering in intervention PCPs relative to control group PCPs (adjusted odds ratio, 1.07 [95% CI, 0.49-2.32]). Rates of test ordering among intervention and control PCPs were similar for all 3 SP cases. The SPs rated visit satisfaction higher among intervention than control PCPs (8.5 [95% CI, 8.1-8.8] vs 7.8 [95% CI, 7.5-8.2], adjusted mean difference, 0.6 [95% CI, 0.1-1.1]). CONCLUSIONS AND RELEVANCE: An SP-based intervention did not improve the patient-centeredness of SP encounters, use of targeted interactional techniques, or rates of low-value test ordering, although SPs were more satisfied with intervention than control residents.

Primary Care Attributes Associated with Receipt of Preventive Care Services: A National Study.

BACKGROUND: Primary care attributes (PCAs) encompassed by patient-centered medical homes may increase receipt of preventive care, though national studies are lacking. METHODS: We performed cross-sectional adjusted analyses of self-report data from adults in the 2007 to 2010 US Medical Expenditure Panel Surveys (N = 50,457). PCAs were considered individually and as a total score for each respondent and included comprehensiveness (a usual source of care for new and ongoing problems, preventive care, and referrals); patient-centeredness (shared decision making); and enhanced access (night and weekend hours). Preventive care measures included mammography, influenza vaccination, annual exams, colorectal cancer screening, and Papanicolaou, prostate-specific antigen, and cholesterol testing. RESULTS: The total PCA score was positively associated with increased receipt of each preventive care measure. Colorectal cancer screening (18.5%) and prostate-specific antigen testing (20.7%) showed the largest increases across PCA score quartiles. Individual primary care attributes except enhanced access were positively associated with each preventive care measure. Enhanced access was negatively associated with annual examination (adjusted odds ratio, 0.83; 95% confidence interval, 0.77-0.91). CONCLUSION: In a nationally representative sample, greater reported exposure to key primary care attributes, with the exception of enhanced access, was associated with increased preventive care. These findings may inform best practices for maximizing preventive care delivery.

The effects of tailoring knowledge acquisition on colorectal cancer screening self-efficacy.

Interventions tailored to psychological factors such as personal and vicarious behavioral experiences can enhance behavioral self-efficacy but are complex to develop and implement. Information seeking theory suggests tailoring acquisition of health knowledge (without concurrent psychological factor tailoring) could enhance self-efficacy, simplifying the design of tailored behavior change interventions. To begin to examine this issue, the authors conducted exploratory analyses of data from a randomized controlled trial, comparing the effects of an experimental colorectal cancer screening intervention tailoring knowledge acquisition with the effects of a nontailored control on colorectal cancer screening knowledge and self-efficacy in 1159 patients comprising three ethnicity/language strata (Hispanic/Spanish, 23.4%, Hispanic/English, 27.2%, non-Hispanic/English, 49.3%) and 5 recruitment center strata. Adjusted for study strata, the mean postintervention knowledge score was significantly higher in the experimental group than in the control group. Adjusted experimental intervention exposure (B = 0.22, 95% CI [0.14, 0.30]), preintervention knowledge (B = 0.11, 95% CI [0.05, 0.16]), and postintervention knowledge (B = 0.03, 95% CI [0.01, 0.05]) were independently associated with subsequent colorectal cancer screening self-efficacy (p < .001 all associations). These exploratory findings suggest that tailoring knowledge acquisition may enhance self-efficacy, with potential implications for tailored intervention design, but this implication requires confirmation in studies specifically designed to examine this issue.

Socio-psychological factors in the Expanded Health Belief Model and subsequent colorectal cancer screening.

OBJECTIVE: CRC screening interventions tailored to the Expanded Health Belief Model (EHBM) socio-psychological factors have been developed, but the contributions of individual factors to screening outcomes are unclear. METHODS: In observational analyses of data from a randomized intervention trial, we examined the independent associations of five EHBM factors - CRC screening knowledge, self-efficacy, stage of readiness, barriers, and discussion with a provider - with objectively measured CRC screening after one year. RESULTS: When all five factors were added simultaneously to a base model including other patient and visit characteristics, three of the factors were associated with CRC screening: self-efficacy (OR=1.32, p=0.001), readiness (OR=2.72, p<0.001), and discussion of screening with a provider (OR=1.59, p=0.009). Knowledge and barriers were not independently associated with screening. Adding the five socio-psychological factors to the base model improved prediction of CRC screening (area under the curve) by 7.7%. CONCLUSION: Patient CRC screening self-efficacy, readiness, and discussion with a provider each independently predicted subsequent screening. PRACTICE IMPLICATIONS: Self-efficacy and readiness measures might be helpful in parsimoniously predicting which patients are most likely to engage in CRC screening. The importance of screening discussion with a provider suggests the potential value of augmenting patient-focused EHBM-tailored interventions with provider-focused elements.

Body mass index and health care utilization in diabetic and nondiabetic individuals.

BACKGROUND: Although controversial, most studies examining the relationship of body mass index (BMI) with mortality in diabetes suggest a paradox: the lowest risk category is above normal weight, versus normal weight in nondiabetic persons. One proposed explanation is greater morbidity of diabetes in normal weight persons. If this were so, it would suggest a health care utilization paradox in diabetes, paralleling the mortality paradox, yet no studies have examined this issue. OBJECTIVE: To compare the relationship of BMI with health care utilization in diabetic versus nondiabetic persons. DESIGN: Population-based cross-sectional study. SUBJECTS: Adults in the 2000-2011 Medical Expenditures Panel Surveys (N=120,389). MEASURES: Total health care expenditures, hospital utilization (≥1 admission), and emergency department utilization (≥1 visit). BMI (kg/m) categories were: <20 (underweight); 20 to <25 (normal); 25 to <30 (overweight); 30 to <35 (obese); and ≥35 (severely obese). Adjustors were age, sex, race/ethnicity, income, health insurance, education, smoking, co-morbidity, urbanicity, region, and year. RESULTS: Among diabetic persons, adjusted mean total health care expenditures were significantly lower in obese versus normal weight persons ($1314, 95% confidence interval [CI], $513-$2115; P=0.001). By contrast, among nondiabetic persons, total expenditures were nonsignificantly higher in obese versus normal weight persons (-$229, 95% CI, -$460 to $2; P=0.052). Findings for hospital and emergency department utilization exhibited similar patterns. CONCLUSIONS: Normal weight diabetic persons used substantially more health care than their overweight and obese counterparts, a difference not observed in nondiabetic persons. These differences support the plausibility of a BMI mortality paradox related to greater morbidity of diabetes in normal weight than in heavier persons.

Potential antidepressant overtreatment associated with office use of brief depression symptom measures.

BACKGROUND: Use of brief depression symptom measures for identifying or screening cases may help to address depression undertreatment, but whether it also leads to diagnosis and treatment of patients with few or no symptoms-a group unlikely to have major depression or benefit from antidepressants-is unknown. We examined the associations of use of a brief depression symptom measure with depression diagnosis and antidepressant recommendation and prescription among patients with few or no depression symptoms. METHODS: We conducted exploratory observational analyses of data from a randomized trial of depression engagement interventions conducted in primary care offices in California. Analyses focused on participants scoring <10 on a study-administered 9-item Patient Health Questionnaire (PHQ-9) (completed immediately before an office visit and not disclosed to the provider) with complete chart review data (n = 595). We reviewed visit notes for evidence of practice administration of a brief symptom measure (independent of the trial) and whether the provider (1) diagnosed depression or (2) recommended and/or prescribed an antidepressant. RESULTS: Among the 545 patients without a practice-administered measure, 57 (10.5%) had a visit diagnosis of depression; 9 (1.6%) were recommended and another 21 (3.8%) prescribed an antidepressant. Among the 50 patients (8.4% of total sample) with a practice-administered measure, 10 (20%) had a visit diagnosis of depression; 6 (12%) were recommended and another 6 (12%) prescribed an antidepressant. Adjusting for nesting within providers, trial intervention, stratification variables, and sample weighting, use of a brief symptom measure was associated with depression diagnosis (adjusted odds ratio, 3.2; 95% confidence interval, 1.1-9.2) and antidepressant recommendation and/or prescription (adjusted odds ratio, 3.80; 95% confidence interval, 1.0-13.9). Analyses using progressively lower PHQ-9 thresholds (<9 to <5) and examining antidepressant prescription alone yielded consistent findings. Analyses by practice-administered measure (PHQ-9 vs PHQ-2) indicated the study findings were largely associated with PHQ-9 use. CONCLUSIONS: These exploratory findings suggest administration of brief depression symptom measures, particularly the PHQ-9, may be associated with depression diagnosis and antidepressant recommendation and prescription among patients unlikely to have major depression. If these findings are confirmed, researchers should investigate the balance of benefits and risks (eg, overdiagnosis of depression and overtreatment with antidepressants) associated with use of a brief symptom measure.

Sociopsychological tailoring to address colorectal cancer screening disparities: a randomized controlled trial.

PURPOSE: Interventions tailored to sociopsychological factors associated with health behaviors have promise for reducing colorectal cancer screening disparities, but limited research has assessed their impact in multiethnic populations. We examined whether an interactive multimedia computer program (IMCP) tailored to expanded health belief model sociopsychological factors could promote colorectal cancer screening in a multiethnic sample. METHODS: We undertook a randomized controlled trial, comparing an IMCP tailored to colorectal cancer screening self-efficacy, knowledge, barriers, readiness, test preference, and experiences with a nontailored informational program, both delivered before office visits. The primary outcome was record-documented colorectal cancer screening during a 12-month follow-up period. Secondary outcomes included postvisit sociopsychological factor status and discussion, as well as clinician recommendation of screening during office visits. We enrolled 1,164 patients stratified by ethnicity and language (49.3% non-Hispanic, 27.2% Hispanic/English, 23.4% Hispanic/Spanish) from 26 offices around 5 centers (Sacramento, California; Rochester and the Bronx, New York; Denver, Colorado; and San Antonio, Texas). RESULTS: Adjusting for ethnicity/language, study center, and the previsit value of the dependent variable, compared with control patients, the IMCP led to significantly greater colorectal cancer screening knowledge, self-efficacy, readiness, test preference specificity, discussion, and recommendation. During the followup period, 132 (23%) IMCP and 123 (22%) control patients received screening (adjusted difference = 0.5 percentage points, 95% CI -4.3 to 5.3). IMCP effects did not differ significantly by ethnicity/language. CONCLUSIONS: Sociopsychological factor tailoring was no more effective than nontailored information in encouraging colorectal cancer screening in a multiethnic sample, despite enhancing sociopsychological factors and visit behaviors associated with screening. The utility of sociopsychological tailoring in addressing screening disparities remains uncertain.

The effect of targeted and tailored patient depression engagement interventions on patient-physician discussion of suicidal thoughts: a randomized control trial.

BACKGROUND: Despite improvements in the diagnosis and treatment of depression, primary care provider (PCP) discussion regarding suicidal thoughts among patients with depressive symptoms remains low. OBJECTIVE: To determine whether a targeted depression public service announcement (PSA) video or an individually tailored interactive multimedia computer program (IMCP) leads to increased primary care provider (PCP) discussion of suicidal thoughts in patients with elevated risk for clinical depression when compared to an attention control. DESIGN: Randomized control trial at five different healthcare systems in Northern California; two academic, two Veterans Affairs (VA), and one group-model health maintenance organization (HMO). PARTICIPANTS: Eight-hundred sixty-seven participants, with mean age 51.7; 43.9% women, 43.4% from a racial/ethnic minority group. INTERVENTION: The PSA was targeted to gender and socio-economic status, and designed to encourage patients to seek depression care or request information regarding depression. The IMCP was an individually tailored interactive health message designed to activate patients to discuss possible depressive symptoms. The attention control was a sleep hygiene video. MAIN MEASURES: Clinician reported discussion of suicidal thoughts. Analyses were stratified by depressive symptom level (Patient Health Questionnaire [PHQ-9] score < 9 [mild or lower] versus ≥ 10 [at least moderate]). KEY RESULTS: Among patients with a PHQ-9 score ≥ 10, PCP discussion of suicidal thoughts was significantly higher in the IMCP group than in the control group (adjusted odds ratio = 2.33, 95% confidence interval = 1.5, 5.10, p = 0.03). There were no significant effects of either intervention on PCP discussion of suicidal thoughts among patients with a PHQ-9 score < 9. CONCLUSIONS: Exposure of patients with at least moderate depressive symptoms to an individually tailored intervention designed to increase patient engagement in depression care led to increased PCP discussion of suicidal thoughts.

Satisfaction with health care providers and preventive care adherence: a national study.

BACKGROUND: Prior studies demonstrating associations between patient satisfaction with health care providers and preventive adherence were cross-sectional, limiting causal inferences. In cross-sectional and prospective analyses, we explored 3 hypotheses previously invoked to explain associations between satisfaction with providers and preventive adherence: (1) receiving preventive care increases satisfaction; (2) enhancing satisfaction increases preventive care; (3) satisfaction and adherence reflect patient characteristics, incompletely adjusted for in previous studies. METHODS: We conducted 3 sets of logistic regression analyses employing 2000-2010 Medical Expenditure Panel Survey data: 1 cross-sectional and 2 prospective (baseline preventive care/follow-up year satisfaction, and baseline satisfaction/follow-up year preventive care), each set cumulatively adjusting for patient demographics, socioeconomics, morbidity, health care access, and medical skepticism. Consumer Assessment of Health Plans Survey items measured satisfaction with care from all providers in the preceding year. Preventive care examined included influenza vaccination and colorectal cancer, Papanicolaou, mammography, and prostate-specific antigen screening. RESULTS: In cross-sectional analyses adjusted for demographics (N = 74,792), highest (vs. lowest) quartile satisfaction was associated with preventive adherence [adjusted odds ratios (95% confidence interval)]: influenza vaccination 1.14 (1.07, 1.22); colorectal cancer screening 1.08 (0.99, 1.18); Papanicolaou screening 1.14 (1.04, 1.24); mammography screening 1.20 (1.11, 1.31); prostate-specific antigen screening 1.38 (1.25, 1.52). With full adjustment, associations of satisfaction with adherence were substantially attenuated, eliminated, or reversed. Prospective analyses yielded findings similar to the cross-sectional analyses. CONCLUSIONS: Cross-sectional and prospective associations between satisfaction with providers and preventive care adherence were similarly explained by patient characteristics. The findings question previously hypothesized causal relationships between satisfaction and preventive adherence.

Health insurance is associated with preventive care but not personal health behaviors.

BACKGROUND: Economists posit 2 mechanisms increasing financial risk to insurers after health insurance gain: ex ante moral hazard (riskier behavior because of reduced personal costs) and ex post moral hazard (increased use of care because of lower care costs). In contrast, the Health Belief Model (HBM), would anticipate no increase in risk behaviors while also predicting increased health care utilization following insurance gain (because of reduced financial barriers to accessing care). Empirical studies examining the association of insurance change with changes in preventive care and health behaviors have been limited and yielded mixed findings. The objective of this study was to examine the association of health insurance change (gain or loss of coverage) with changes in preventive care and health behaviors in a large, nationally representative sample. METHODS: We analyzed data from adults ≥18 years old and enrolled for 2 years in the 2000 to 2009 Medical Expenditure Panel Surveys (n = 76,518). Conditional logistic regression analyses modeled year-to-year individual changes in preventive care and health behaviors associated with individual changes in insurance status, adjusting for characteristics varying year to year (income, employment, total health care expenditures, office visits, prescriptions, availability of usual source of care, and health status). Preventive care included adherence to influenza vaccination, colorectal cancer screening, mammography, and Papanicolaou and prostate-specific antigen testing. Health behaviors examined were becoming nonobese, quitting smoking, and adopting consistent use of seatbelts. RESULTS: Insurance gain (loss) was associated with increases (decreases) in preventive care (adjusted odds ratios [95% confidence intervals]: influenza vaccine, 1.27 [1.04-1.56]; colorectal cancer screening, 1.48 [0.96-2.29]; Papanicolaou testing, 1.56 [1.22-2.00]; mammography, 1.70 [1.21-2.38]; prostate-specific antigen, 1.42 [0.98-2.05]). Insurance change was not associated with significant changes in health behaviors. CONCLUSIONS: Consistent with both economic theory and the HBM, preventive care increased (decreased) after gaining (losing) coverage. In contrast, health behaviors changed little after insurance change, consistent with the HBM but not with the potential for decreased personal health care costs (ex ante moral hazard).

The effects of two health information texts on patient recognition memory: a randomized controlled trial.

OBJECTIVE: To compare the effects of two health information texts on patient recognition memory, a key aspect of comprehension. METHODS: Randomized controlled trial (N=60), comparing the effects of experimental and control colorectal cancer (CRC) screening texts on recognition memory, measured using a statement recognition test, accounting for response bias (score range -0.91 to 5.34). The experimental text had a lower Flesch-Kincaid reading grade level (7.4 versus 9.6), was more focused on addressing screening barriers, and employed more comparative tables than the control text. RESULTS: Recognition memory was higher in the experimental group (2.54 versus 1.09, t=-3.63, P=0.001), including after adjustment for age, education, and health literacy (ß=0.42, 95% CI: 0.17, 0.68, P=0.001), and in analyses limited to persons with college degrees (ß=0.52, 95% CI: 0.18, 0.86, P=0.004) or no self-reported health literacy problems (ß=0.39, 95% CI: 0.07, 0.71, P=0.02). CONCLUSION: An experimental CRC screening text improved recognition memory, including among patients with high education and self-assessed health literacy. PRACTICE IMPLICATIONS: CRC screening texts comparable to our experimental text may be warranted for all screening-eligible patients, if such texts improve screening uptake.

Effects of tailored knowledge enhancement on colorectal cancer screening preference across ethnic and language groups.

OBJECTIVE: Tailoring to psychological constructs (e.g. self-efficacy, readiness) motivates behavior change, but whether knowledge tailoring alone changes healthcare preferences--a precursor of behavior change in some studies--is unknown. We examined this issue in secondary analyses from a randomized controlled trial of a tailored colorectal cancer (CRC) screening intervention, stratified by ethnicity/language subgroups (Hispanic/Spanish, Hispanic/English, non-Hispanic/English). METHODS: Logistic regressions compared effects of a CRC screening knowledge-tailored intervention versus a non-tailored control on preferences for specific test options (fecal occult blood or colonoscopy), in the entire sample (N=1164) and the three ethnicity/language subgroups. RESULTS: Pre-intervention, preferences for specific tests did not differ significantly between study groups (experimental, 64.5%; control 62.6%). Post-intervention, more experimental participants (78.6%) than control participants (67.7%) preferred specific tests (P<0.001). Adjusting for pre-intervention preferences, more experimental group participants than control group participants preferred specific tests post-intervention [average marginal effect (AME)=9.5%, 95% CI 5.3-13.6; P<0.001]. AMEs were similar across ethnicity/language subgroups. CONCLUSION: Knowledge tailoring increased preferences for specific CRC screening tests across ethnic and language groups. PRACTICE IMPLICATIONS: If the observed preference changes are found to translate into behavior changes, then knowledge tailoring alone may enhance healthy behaviors.

Lifetime earnings for physicians across specialties.

BACKGROUND: Earlier studies estimated annual income differences across specialties, but lifetime income may be more relevant given physicians' long-term commitments to specialties. METHODS: Annual income and work hours data were collected from 6381 physicians in the nationally representative 2004-2005 Community Tracking Study. Data regarding years of residency were collected from AMA FREIDA. Present value models were constructed assuming 3% discount rates. Estimates were adjusted for demographic and market covariates. Sensitivity analyses included 4 alternative models involving work hours, retirement, exogenous variables, and 1% discount rate. Estimates were generated for 4 broad specialty categories (Primary Care, Surgery, Internal Medicine and Pediatric Subspecialties, and Other), and for 41 specific specialties. RESULTS: The estimates of lifetime earnings for the broad categories of Surgery, Internal Medicine and Pediatric Subspecialties, and Other specialties were $1,587,722, $1,099,655, and $761,402 more than for Primary Care. For the 41 specific specialties, the top 3 (with family medicine as reference) were neurological surgery ($2,880,601), medical oncology ($2,772,665), and radiation oncology ($2,659,657). The estimates from models with varying rates of retirement and including only exogenous variables were similar to those in the preferred model. The 1% discount model generated estimates that were roughly 150% larger than the 3% model. CONCLUSIONS: There was considerable variation in the lifetime earnings across physician specialties. After accounting for varying residency years and discounting future earnings, primary care specialties earned roughly $1-3 million less than other specialties. Earnings' differences across specialties may undermine health reform efforts to control costs and ensure adequate numbers of primary care physicians.

Body mass index, diabetes, hypertension, and short-term mortality: a population-based observational study, 2000-2006.

BACKGROUND: Published studies about the association of obesity with mortality have used body mass index (BMI) data collected more than 10 years ago, potentially limiting their current applicability, particularly given evidence of a secular decline in obesity-related mortality. The objective of this study was to examine the association between BMI and mortality in a representative, contemporary United States sample. METHODS: This was a population-based observational study of data from 50,994 adults aged 18 to 90 years who responded to the 2000 to 2005 Medical Expenditures Panel Surveys. Cox regression analyses were employed to model survival during up to 6 years of follow-up (ascertained via National Death Index linkage) by self-reported BMI category (underweight, <20 kg/m(2); normal weight, 20-<25 [reference]; overweight, 25-<30; obese, 30-<35; severely obese, ≥35), without and with adjustment for diabetes and hypertension. Survival by BMI category also was modeled for diabetic and hypertensive individuals. All models were adjusted for sociodemographics, smoking, and Medical Expenditures Panel Surveys response year. RESULTS: In analyses not adjusted for diabetes or hypertension, only severe obesity was associated with mortality (adjusted hazard ratio, 1.26; 95% confidence interval, 1.00-1.59). After adjusting for diabetes and hypertension, severe obesity was no longer associated with mortality, and milder obesity (BMI 30-<35) was associated with decreased mortality (adjusted hazard ratio, 0.81; 95% confidence interval, 0.68-0.97). There was a significant interaction between diabetes (but not hypertension) and BMI (F [4, 235] = 2.71; P = .03), such that the mortality risk of diabetes was lower among mildly and severely obese persons than among those in lower BMI categories. CONCLUSIONS: Obesity-associated mortality risk was lower than estimated in studies employing older BMI data. Only severe obesity (but not milder obesity or overweight) was associated with increased mortality, an association accounted for by coexisting diabetes and hypertension. Mortality in diabetes was lower among obese versus normal weight individuals.
