Development of a Telehealth Intervention to Improve Access to Live Donor Kidney Transplantation.

BACKGROUND: Live donor kidney transplantation (LDKT) is underutilized by patients with end-stage kidney disease due to knowledge, communication, and logistical barriers. MATERIAL AND METHODS: The Talking About Live Kidney Donation Social Worker Intervention (TALK-SWI) is a previously validated intervention demonstrated to improve patients' access to and pursuit of LDKT through in-person delivery of education and social support. To help overcome logistical barriers to LDKT, we adapted TALK-SWI into a telehealth intervention employing digital (ie, tablet, smartphone) and telephone technologies. We studied the usability and acceptability of both the mobile device and telephone counseling portions of the intervention among people with kidney disease. For the digital portion, we assessed critical (ie, inability to complete a task) and non-critical (ie, ability to complete a task utilizing an alternative method) errors participants encountered when using the program and their preferences regarding digital materials. Simultaneously, we assessed participants' satisfaction with telephone-adapted counseling compared to the original, in-person counseling. RESULTS: The 15 participants testing the digital technology made 25 critical errors and 29 non-critical errors, while they easily completed 156 tasks (out of 210). A majority of participants (73%) preferred the tablet/smart phone education application over traditional materials, and most (80%) indicated they would be more likely to utilize the mobile platform over traditional materials. Participants testing the telephone-adapted (n = 45) and in-person (n = 125) social worker counseling all reported high satisfaction with the intervention. CONCLUSION: We successfully adapted a validated educational and behavioral intervention to improve access to LDKT into a usable and acceptable telehealth intervention.

Putting patients at the center of kidney care transitions: PREPARE NOW, a cluster randomized controlled trial.

Care for patients transitioning from chronic kidney disease to kidney failure often falls short of meeting patients' needs. The PREPARE NOW study is a cluster randomized controlled trial studying the effectiveness of a pragmatic health system intervention, 'Patient Centered Kidney Transition Care,' a multi-component health system intervention designed to improve patients' preparation for kidney failure treatment. Patient-Centered Kidney Transition Care provides a suite of new electronic health information tools (including a disease registry and risk prediction tools) to help providers recognize patients in need of Kidney Transitions Care and focus their attention on patients' values and treatment preferences. Patient-Centered Kidney Transition Care also adds a 'Kidney Transitions Specialist' to the nephrology health care team to facilitate patients' self-management empowerment, shared-decision making, psychosocial support, care navigation, and health care team communication. The PREPARE NOW study is conducted among eight [8] outpatient nephrology clinics at Geisinger, a large integrated health system in rural Pennsylvania. Four randomly selected nephrology clinics employ the Patient Centered Kidney Transitions Care intervention while four clinics employ usual nephrology care. To assess intervention effectiveness, patient reported, biomedical, and health system outcomes are collected annually over a period of 36 months via telephone questionnaires and electronic health records. The PREPARE NOW Study may provide needed evidence on the effectiveness of patient-centered health system interventions to improve nephrology patients' experiences, capabilities, and clinical outcomes, and it will guide the implementation of similar interventions elsewhere. TRIAL REGISTRATION: NCT02722382.

The short-term impact of tailored mammography decision-making interventions.

BACKGROUND: We assessed the short-term impact of decision-making interventions on knowledge about mammography, accuracy of women's breast cancer risk perceptions, attitudes toward mammography, satisfaction with decisions, and mammography use since the intervention. METHODS: The study was conducted among women who were members of Blue Cross Blue Shield of North Carolina and were in their 40s or 50s at the time the study began in 1997. Women were randomly assigned to usual care (UC), tailored print booklets (TP) alone, or TP plus telephone counseling (TP+TC ). RESULTS: 12-month interviews were completed by 1127 women to assess short-term intervention effects. Generally, women who received TP+TC were significantly more knowledgeable about mammography and breast cancer risk and were more accurate in their breast cancer risk perceptions than women in the TP and UC groups. They also were more likely to have had a mammogram since the baseline interview. In multivariable analyses, we found significant benefits of the combination of TP+TC compared to TP and to UC for knowledge, accuracy of risk perceptions, and mammography use. DISCUSSION: For complex decision-making tasks, such as women's decisions about mammography in the face of controversy, the combination of TP and TC may be more effective than TP alone, and certainly more effective than UC. It is critical that investigators determine the topics for which TP is appropriate and the situations that require additional supportive interventions.

Factors associated with repeat mammography screening.

BACKGROUND: Even organizations with differing mammography recommendations agree that regular repeat screening is required for mortality reduction. However, most studies have focused on one-time screening rather than repeat adherence. We compare trends in beliefs and health-related behaviors among women screened and adherent to the National Cancer Institute's screening mammography recommendations (on schedule), those screened at least once and nonadherent (off schedule), and those never screened. METHODS: Our data are from a baseline telephone interview conducted among 1,287 female members of Blue Cross Blue Shield of North Carolina who were aged either 40 to 44 years or 50 to 54 years. RESULTS: The 3 groups differed significantly on beliefs and health-related behaviors, with the off-schedule group almost consistently falling between the on-schedule and never screened groups. Off-schedule women were more likely than on-schedule women, but less likely than those never screened, to not have a clinical breast examination within 12 months, to be ambivalent about screening mammography, to be confused about screening guidelines, and to not be advised by a physician to get a mammogram in the past 2 years. Off-schedule women perceived their breast cancer risk as lower and were less likely to be up to date with other cancer screening tests. CONCLUSIONS: Our findings suggest that women who are off schedule are in need of mammography-promoting interventions, including recommendations from and discussion with their health care providers. Because they are more positive and knowledgeable about mammography than women who have never been screened, they may benefit from brief interventions from health care providers that highlight the importance of repeat screening.

The impact of abnormal mammograms on psychosocial outcomes and subsequent screening.

Few studies have examined the impact of abnormal mammograms on subsequent mammography screening and psychosocial outcomes specifically as a function of the length of time that has passed since the abnormal test result. This cross-sectional report compared breast cancer screening practices and psychosocial outcomes among three groups of women. These groups were women who (1) never had an abnormal mammogram, (2) had an abnormal mammogram 2 or more years prior to the study's baseline interview, and (3) had an abnormal mammogram within 2 years prior to the study's baseline interview. Women who had an abnormal mammogram at least 2 years prior to the baseline interview expressed greater 10-year and lifetime risks of getting breast cancer than women who never had an abnormal mammogram. Women who had abnormal mammograms, independent of when they occurred, were substantially more worried about getting breast cancer than were women who never had abnormal mammograms. Women who had an abnormal mammogram within 2 years prior to the baseline interview were more likely to be on schedule for mammography, compared with women who never had an abnormal mammogram.

Feasibility of a tailored intervention to improve preventive care use in women.

BACKGROUND: Women age 50 years and older are in need of multiple preventive health care services. Despite recent improvements in rates of delivery of preventive care services, especially within managed care organizations, substantial numbers of women are still being underscreened. Efforts to improve delivery of preventive care services have often focused on one outstanding service despite the fact that patients often are in need of many services. METHODS: A total of 893 women age 50 to 55 years were mailed a self-administered survey to identify outstanding preventive health care service needs. Patients in need of three or more outstanding preventive health care services were identified from survey respondents to participate in a feasibility study evaluating a tailored, customized intervention called Tic Tac Health. RESULTS: Five-hundred ninety-one women returned the survey (67%). Four-hundred forty-eight (76%) women were in need of one or more preventive health services; 92 (16%) were in need of three or more. Twenty-two patients (24%) completed the Tic Tac Health card. The women who completed the card were similar to those who did not. CONCLUSIONS: Despite documented physician visits, presence of managed care health insurance, and a designated primary care provider, a significant number of women are still in need of multiple preventive health services. An intervention targeting multiple preventive health services was demonstrated to be both feasible and effective. Further evaluation via a randomized controlled trial should be conducted to determine if an intervention like Tic Tac Health would be an effective modality for improving rates of receipt of multiple preventive health care services.

Can tailored interventions increase mammography use among HMO women?

BACKGROUND: Telephone counseling and tailored print communications have emerged as promising methods for promoting mammography screening. However, there has been little research testing, within the same randomized field trial, of the efficacy of these two methods compared to a high-quality usual care system for enhancing screening. This study addressed the question: Compared to usual care, is tailored telephone counseling more effective than tailored print materials for promoting mammography screening? DESIGN: Three-year randomized field trial. PARTICIPANTS: One thousand ninety-nine women aged 50 and older recruited from a health maintenance organization in North Carolina. INTERVENTION: Women were randomized to 1 of 3 groups: (1) usual care, (2) tailored print communications, and (3) tailored telephone counseling. MAIN OUTCOME: Adherence to mammography screening based on self-reports obtained during 1995, 1996, and 1997. RESULTS: Compared to usual care alone, telephone counseling promoted a significantly higher proportion of women having mammograms on schedule (71% vs 61%) than did tailored print (67% vs 61%) but only after the first year of intervention (during 1996). Furthermore, compared to usual care, telephone counseling was more effective than tailored print materials at promoting being on schedule with screening during 1996 and 1997 among women who were off-schedule during the previous year. CONCLUSIONS: The effects of the intervention were most pronounced after the first intervention. Compared to usual care, telephone counseling seemed particularly effective at promoting change among nonadherent women, the group for whom the intervention was developed. These results suggest that telephone counseling, rather than tailored print, might be the preferred first-line intervention for getting nonadherent women on schedule for mammography screening. Many questions would have to be answered about why the tailored print intervention was not more powerful. Nevertheless, it is clear that additional interventions will be needed to maintain women's adherence to mammography. Medical Subject Headings (MeSH): mammography screening, telephone counseling, tailored print communications, barriers.

Confusion about mammography: prevalence and consequences.

Over the last decade, there has been significant controversy about the schedule on which women, particularly women in their 40s, should have mammograms. The purpose of the analysis reported here was to assess whether women in their 40s and 50s were confused as a result of the controversy following the January 1997 National Institutes of Health Consensus Development Conference on Breast Cancer Screening For Women Ages 40-49. We also examined if confusion was related to being off schedule for mammography. The study sample included 1287 women recruited from a random sample of 2165 Blue Cross/Blue Shield of North Carolina members. The data described in this analysis were derived from a baseline telephone interview conducted as part of a larger intervention trial. Study measures included a variety of sociodemographic, medical, belief, and behavioral variables. Overall, 28% of women were confused, and 35% were off schedule. Although a higher proportion of women in their 40s than 50s were confused, more women in their 50s were off schedule. Confusion was a significant predictor for the outcome being off schedule. Predictors of confusion included several belief variables, risk perceptions, age (40s), whether the woman had a regular physician, and whether she had enough information about mammography. Healthcare providers should ask some simple questions to determine if women are confused and then seek to meet their information needs.

Serum androgens: associations with prostate cancer risk and hair patterning.

Cancer of the prostate is the leading cancer among American men, yet few risk factors have been established. Hair growth and development are influenced by androgens, and it has long been suspected that prostate cancer also is responsive to these hormones. A blinded, case-control study was undertaken to determine if hair patterning is associated with risk of prostate cancer, as well as specific hormonal profiles. The study accrued 315 male subjects who were stratified with regard to age, race, and case-control status (159 prostate cancer cases/156 controls). Hair-patterning classification and serum levels of total and free testosterone (T), sex hormone binding globulin, and dihydrotestosterone (DHT) were performed. Data indicate that hair patterning did not differ between prostate cancer cases and controls; however, significant hormonal differences were detected between the two groups. Free T was greater among cases than in controls (16.4 +/- 6.1 vs. 14.9 +/- 4.8 pg/ml, P = 0.02). Conversely, DHT-related ratios were greater among controls (P = 0.03 for DHT/T and P = 0.01 for DHT/free T). Several strong associations also were found between hormone levels and hair patterning. Men with vertex and frontal baldness had higher levels of free T (16.5 +/- 5.5 and 16.2 +/- 8.0 pg/ml, respectively) when compared to men with either little or no hair loss (14.8 +/- 4.7 pg/ml) (P = 0.01). Data suggest that increased levels of free T may be a risk factor for prostatic carcinoma. In addition, although no differences in hair patterning were detected between cases and controls within this older population, further research (i.e., prospective trials or case-control studies among younger men) may be necessary to determine if hair patterning serves as a viable biomarker for this disease, especially given the strong association between free T levels and baldness.

Genetic testing for breast cancer susceptibility: awareness and interest among women in the general population.

Previous research has suggested that demand for genetic testing for breast cancer susceptibility may be quite high, even among those at relatively low risk of carrying a mutation. This study examined the extent to which a group of female HMO enrollees were aware of the discovery of the BRCA1 gene and, without having received detailed information about the test, whether they would be interested in being tested to find out if they have the gene. Factors associated with awareness of and interest in testing were also examined. Four hundred seventy-three women age 50 and over, almost all of whom did not have an increased risk of breast cancer based on family history, were surveyed by telephone. Fifty-one percent of respondents had heard about the discovery of a breast cancer gene. In logistic regression analysis, women who described themselves as comfortable financially, had at least some college education, and were premenopausal were more likely to have heard of the gene discovery than women who were not comfortable financially, had no more than a high school education, and were postmenopausal. Sixty-nine percent of the respondents said that they would be interested in being tested to find out if they had a breast cancer gene. Women who were younger than 60, white, believed their family would benefit if they had a mammogram, and believed that regular mammograms give them a feeling of control over their health, were more likely to be interested in testing than those who were 60 or older, African-American or other, and did not believe that their family would benefit if they had a mammogram or that mammograms give them a feeling of control over their health. These findings have implications for education and counseling. Women who express an interest in being tested must be made fully aware of the limitations and possible consequences of testing. Special efforts may be needed to make information about testing available to women who have low levels of education.

Relationships among objective and subjective risk for breast cancer and mammography stages of change.

This study examined the relationships among objective and subjective risk for breast cancer and mammography stages of change as defined by the Transtheoretical Model. Women who had higher objective risk of breast cancer, as defined by the Gail et al. algorithm (M. H. Gail et al., J. Natl. Cancer Inst., 81: 1879-1886, 1989), were more likely to perceive themselves at greater subjective risk for breast cancer. Among the components of objective risk, family history of breast cancer was the only significant predictor of subjective risk. Both objective and subjective risk individually predicted stages of change, such that higher objective and subjective risk were associated with an increased probability of being in a later stage of adopting mammography. However, when objective and subjective risk were included in a multivariate model, only subjective risk predicted stages of change. In additional multivariate analyses, subjective risk continued to predict mammography stages of change when "con" and "decisional balance" scores were included in separate models. These results suggest that future research may benefit from the explicit integration of personal risk perceptions with elements of the Transtheoretical Model to provide more powerful accounts of behavioral change processes.
