Narrative communication in cancer prevention and control: a framework to guide research and application.

Narrative forms of communication—including entertainment education, journalism, literature, testimonials, and storytelling—are emerging as important tools for cancer prevention and control. To stimulate critical thinking about the role of narrative in cancer communication and promote a more focused and systematic program of research to understand its effects, we propose a typology of narrative application in cancer control. We assert that narrative has four distinctive capabilities: overcoming resistance, facilitating information processing, providing surrogate social connections, and addressing emotional and existential issues. We further assert that different capabilities are applicable to different outcomes across the cancer control continuum (e.g., prevention, detection, diagnosis, treatment, survivorship). This article describes the empirical evidence and theoretical rationale supporting propositions in the typology, identifies variables likely to moderate narrative effects, raises ethical issues to be addressed when using narrative communication in cancer prevention and control efforts, and discusses potential limitations of using narrative in this way. Future research needs based on these propositions are outlined and encouraged.

Teaching the Teachers: National Survey of Faculty Development in Departments of Medicine of U.S. Teaching Hospitals

OBJECTIVE: To determine the prevalence, topics, methods, and intensity of ongoing faculty development (FD) in teaching skills.DESIGN: Mailed survey.PARTICIPANTS: Two hundred and seventy-seven of the 386 (72%) U.S. teaching hospitals with internal medicine residency programs.MEASUREMENTS: Prevalence and characteristics of ongoing FD.RESULTS: One hundred and eight teaching hospitals (39%) reported ongoing FD. Hospitals with a primary medical school affiliation (university hospitals) were more likely to have ongoing FD than nonuniversity hospitals. For nonuniversity hospitals, funding from the Health Resources Services Administration and >50 house staff were associated with ongoing FD. For university hospitals, >100 department of medicine faculty was associated. Ongoing programs included a mean of 10.4 topics (standard deviation, 5.4). Most offered half-day workshops (80%), but 22% offered ≥1-month programs. Evaluations were predominantly limited to postcourse evaluations forms. Only 14% of the hospitals with ongoing FD (5% of all hospitals) had “advanced” programs, defined as offering ≥10 topics, lasting >2 days, and using ≥3 experiential teaching methods. These were significantly more likely to be university hospitals and to offer salary support and/or protected time to their FD instructors. Generalists and hospital-based faculty were more likely to receive training than subspecialist and community-based faulty. Factors facilitating participation in FD activities were supervisor attitudes, FD expertise, and institutional culture.CONCLUSIONS: A minority of U.S. teaching hospitals offer ongoing faculty development in teaching skills. Continued progress will likely require increased institutional commitment, improved evaluations, and adequate resources, particularly FD instructors and funding.

Active and passive smoking and development of glucose intolerance among young adults in a prospective cohort: CARDIA study

Abstract Objective To assess whether active and passive smokers are more likely than non-smokers to develop clinically relevant glucose intolerance or diabetes. Design Coronary artery risk development in young adults (CARDIA) is a prospective cohort study begun in 1985-6 with 15 years of follow-up. Setting Participants recruited from Birmingham, Alabama; Chicago, Illinois; Minneapolis, Minnesota; and Oakland, California, USA. Participants Black and white men and women aged 18-30 years with no glucose intolerance at baseline, including 1386 current smokers, 621 previous smokers, 1452 never smokers with reported exposure to secondhand smoke (validated by serum cotinine concentrations 1-15 ng/ml), and 1113 never smokers with no exposure to secondhand smoke. Main outcome measure Time to development of glucose intolerance (glucose ≥ 100 mg/dl or taking antidiabetic drugs) during 15 years of follow-up. Results Median age at baseline was 25, 55% of participants were women, and 50% were African-American. During follow-up, 16.7% of participants developed glucose intolerance. A graded association existed between smoking exposure and the development of glucose intolerance. The 15 year incidence of glucose intolerance was highest among smokers (21.8%), followed by never smokers with passive smoke exposure (17.2%), and then previous smokers (14.4%); it was lowest for never smokers with no passive smoke exposure (11.5%). Current smokers (hazard ratio 1.65, 95% confidence interval 1.27 to 2.13) and never smokers with passive smoke exposure (1.35, 1.06 to 1.71) remained at higher risk than never smokers without passive smoke exposure after adjustment for multiple baseline sociodemographic, biological, and behavioural factors, but risk in previous smokers was similar to that in never smokers without passive smoke exposure. Conclusion These findings support a role of both active and passive smoking in the development of glucose intolerance in young adulthood.

Culturally appropriate storytelling to improve blood pressure: a randomized trial

BACKGROUND Storytelling is emerging as a powerful tool for health promotion in vulnerable populations. However, these interventions remain largely untested in rigorous studies. OBJECTIVE To test an interactive storytelling intervention involving DVDs. DESIGN Randomized, controlled trial in which comparison patients received an attention control DVD. Separate random assignments were performed for patients with controlled or uncontrolled hypertension. (ClinicalTrials.gov registration number: NCT00875225) SETTING An inner-city safety-net clinic in the southern United States. PATIENTS 230 African Americans with hypertension. INTERVENTION 3 DVDs that contained patient stories. Storytellers were drawn from the patient population. MEASUREMENTS The outcomes were differential change in blood pressure for patients in the intervention versus the comparison group at baseline, 3 months, and 6 to 9 months. RESULTS 299 African American patients were randomly assigned between December 2007 and May 2008 and 76.9% were retained throughout the study. Most patients (71.4%) were women, and the mean age was 53.7 years. Baseline mean systolic and diastolic pressures were similar in both groups. Among patients with baseline uncontrolled hypertension, reduction favored the intervention group at 3 months for both systolic (11.21 mm Hg [95% CI, 2.51 to 19.9 mm Hg]; P = 0.012) and diastolic (6.43 mm Hg [CI, 1.49 to 11.45 mm Hg]; P = 0.012) blood pressures. Patients with baseline controlled hypertension did not significantly differ over time between study groups. Blood pressure subsequently increased for both groups, but between-group differences remained relatively constant. LIMITATION This was a single-site study with 23% loss to follow-up and only 6 months of follow-up. CONCLUSION The storytelling intervention produced substantial and significant improvements in blood pressure for patients with baseline uncontrolled hypertension.

Disparities in Use of a Personal Health Record in a Managed Care Organization

OBJECTIVE Personal health records (PHRs) can increase patient access to health care information. However, use of PHRs may be unequal by race/ethnicity. DESIGN The authors conducted a 2-year cohort study (2005-2007) assessing differences in rates of registration with KP.org, a component of the Kaiser Permanente electronic health record (EHR). MEASUREMENTS At baseline, 1,777 25-59 year old Kaiser Permanente Georgia enrollees, who had not registered with KP.org, responded to a mixed mode (written or Internet) survey. Baseline, EHR, and KP.org data were linked. Time to KP.org registration by race from 10/1/05 (with censoring for disenrollment from Kaiser Permanente) was adjusted for baseline education, comorbidity, patient activation, and completion of the baseline survey online vs. by paper using Cox proportional hazards. RESULTS Of 1,777, 34.7% (616) registered with KP.org between Oct 2005 and Nov 2007. Median time to registering a KP.org account was 409 days. Among African Americans, 30.1% registered, compared with 41.7% of whites (p < 0.01). In the hazards model, African Americans were again less likely to register than whites (hazard ratio [HR] = 0.652, 95% CI: 0.549-0.776) despite adjustment. Those with baseline Internet access were more likely to register (HR = 1.629, 95% CI: 1.294-2.050), and a significant educational gradient was also observed (more likely registration with higher educational levels). CONCLUSIONS Differences in education, income, and Internet access did not account for the disparities in PHR registration by race. In the short-term, attempts to improve patient access to health care with PHRs may not ameliorate prevailing disparities between African Americans and whites.

Patient Smoking Cessation Advice by Health Care Providers: The Role of Ethnicity, Socioeconomic Status, and Health

OBJECTIVES We assessed differences by ethnicity in ever receiving advice from providers to quit smoking. We evaluated whether socioeconomic status and health status were moderators of the association. METHODS We used 2000 Behavioral Risk Factor Surveillance Survey data, a population-based cross-sectional survey. RESULTS After adjusting for complex survey design, 69% of the 14089 current smokers reported ever being advised to quit by a provider. Hispanics (50%) and African Americans (61%) reported receiving smoking counseling less frequently compared with Whites (72%, P<.01 for each). Ethnic minority status, lower education, and poorer health status remained significantly associated with lower rates of advice to quit after adjustment for number of cigarettes, time from last provider visit, income, comorbidities, health insurance, gender, and age. Smoking counseling differences between African Americans and Whites were greater among those with lower income and those without health insurance. Compared with Whites, differences for both Hispanics and African Americans were also greater among those with lower education. CONCLUSION We found lower rates of smoking cessation advice among ethnic minorities. However, we also found complex interactions of ethnicity with socioeconomic factors.

The attributable risk of smoking on surgical complications.

Objective:This study aimed to assess the attributable risk and potential benefit of smoking cessation on surgical outcomes. Summary Background Data:Risk reduction with the implementation of surgical care improvement project process measures has been the primary focus for improving surgical outcomes. Little emphasis has been placed on preoperative risk factor recognition and intervention. Methods:A retrospective cohort analysis of elective operations from 2002 to 2008 in the Veterans Affairs Surgical Quality Improvement Program for all surgical specialties was performed. Patients were stratified by current, prior, and never smokers. Adjusted risk of complication and death was calculated using multilevel, multivariable logistic regression. Results:Of 393,794 patients, 135,741 (34.5%) were current, 71,421 (18.1%) prior, and 186,632 (47.4%) never smokers. A total of 6225 pneumonias, 11,431 deep and superficial surgical-site infections, 2040 thromboembolic events, 1338 myocardial infarctions, and 4792 deaths occurred within 30 days of surgery. Compared with both never and prior smokers individually and controlled for patient and procedure risk factors, current smokers had significantly more postoperative pneumonia, surgical-site infection, and deaths (P < 0.001 for all). There was a dose-dependent increase in pulmonary complications based on pack-year exposure with greater than 20 pack years leading to a significant increase in smoking-related surgical complications. Conclusions:This is the first study to assess the risk of current versus prior smoking on surgical outcomes. Despite being younger and healthier, current smokers had more adverse perioperative events, particularly respiratory complications. Smoking cessation interventions could potentially reduce the occurrence and costs of adverse perioperative events.

Beliefs and Attitudes Associated With the Intention to Not Accept the Diagnosis of Depression Among Young Adults

PURPOSE Negative attitudes and beliefs about depression treatment may prevent many young adults from accepting a diagnosis and treatment for depression. We undertook a study to determine the association between depressive symptom severity, beliefs about and attitudes toward treatment, subjective social norms, and past behavior on the intent not to accept a physician’s diagnosis of depression. METHODS We conducted a cross-sectional study of 10,962 persons aged 16 to 29 years who participated and had positive screening results on the Center for Epidemiologic Studies Depression (CES-D) score in an Internet-based public health depression screening program. Participants reported whether they would accept their physician’s diagnosis of depression. Based on the theory of reasoned action, we developed a multivariate model of the factors that predict intent not to accept a diagnosis of depression. RESULTS Twenty-six percent of the participants stated their intent not to accept their physician’s diagnosis of depression. Disagreeing that medications are effective in treating depression (strongly disagree, odds ratio ( OR ) = 6.5, 95% confidence interval (CI), 4.6–9.3), that there is a biological cause for depression (strongly disagree, OR = 1.9, 95% CI, 1.3–2.7), and agreeing that you would be embarrassed if your friends knew you had depression were associated with the intent not to accept a diagnosis of depression (strongly agree, OR = 2.3, 95% CI, 1.8–2.9). Beliefs and attitudes, subjective social norms, and past behavior explained most of the variance in this model (84%). CONCLUSIONS Negative beliefs and attitudes, subjective social norms, and lack of past helpful treatment experiences are associated with the intent to not accept the diagnosis of depression and may contribute to low rates of treatment among young adults.

Association of Timely Administration of Prophylactic Antibiotics for Major Surgical Procedures and Surgical Site Infection

BACKGROUND Prophylactic antibiotic (PA) administration 1 to 2 hours before surgical incision (SIP-1) is a publicly reported process measure proposed for performance pay. We performed an analysis of patients undergoing major surgical operations to determine if SIP-1 was associated with surgical site infection (SSI) rates in Department of Veterans Affairs (VA) hospitals. STUDY DESIGN Patients with External Peer Review Program Surgical Care Improvement Project (SCIP)-1 data with matched National Surgical Quality Improvement Program data were included in the study. Patient and facility level analyses comparing SCIP-1 and SSI were performed. We adjusted for clustering effects within hospitals, validated SSI risk score, and procedure type (percentage of colon, vascular, orthopaedic) using generalized estimating equations and linear modeling. RESULTS The study population included 9,195 elective procedures (5,981 orthopaedic, 1,966 colon, and 1,248 vascular) performed in 95 VA hospitals. Timely PA occurred in 86.4% of patients. Untimely PA was associated with a rate of SSI of 5.8%, compared with 4.6% in the timely group (odds ratio = 1.29, 95% CI 0.99, 1.67) in bivariable unadjusted analysis. Patient level risk-adjusted multivariable generalized estimating equation modeling found the SSI risk score was predictive of SSI (p < 0.001); SIP-1 was not associated with SSI. Hospital level multivariable generalized linear modeling found procedure mix (p < 0.0001), but not SIP-1 rate or facility volume, to be associated with facility SSI rate. The study had 80% power to detect a 1.75% difference for patient level SSI rates. CONCLUSIONS Timely PA did not markedly contribute to overall patient or facility SSI rates. These data are important for the ongoing discourse on how to measure and pay for quality of surgical care.
