Adherence to a dietary fat intake reduction program in postmenopausal women receiving therapy for early breast cancer. The Women's Intervention Nutrition Study.

PURPOSE: To evaluate the feasibility of integrating a program based on dietary fat intake reduction into adjuvant treatment strategies for postmenopausal women receiving therapy for early breast cancer. PATIENTS AND METHODS: Two hundred ninety postmenopausal women with localized (stage I to IIIa) breast cancer receiving conventional systemic therapy provided informed consent and were randomized in a multicenter trial to either a dietary intervention group receiving a program of individualized instruction for reducing total fat intake or a dietary control group with minimal dietary counseling. RESULTS: Significantly reduced (P < .001) fat intake (in terms of percent calories derived from fat) was observed in the intervention group versus the control group at 3 months (20.3% +/- 2.4% v 31.5% +/- 2.6%, mean +/- SD, respectively) and maintained throughout 24 months of observation. The 50% reduction in daily fat-gram intake (from 66 +/- 23 to 33 +/- 14 g, P < .001) seen at 6 months was associated with reduced saturated fat, monounsaturated fat, polyunsaturated fat, and linoleic acid (P < .001). Significantly lower body weight was also seen in intervention compared with control patients at all observation periods, resulting in a 3.3-kg weight difference 18 months after randomization (P < .001). CONCLUSION: Substantial and sustained dietary fat reduction with associated weight change can be achieved at relatively low cost within the context of conventional multimodality clinical management of postmenopausal women with localized breast cancer. This result supports the feasibility of conducting a full-scale evaluation of the influence of dietary fat intake reduction on the clinical outcome of breast cancer patients.

Tumoral calcinosis of the filum terminale.

OBJECTIVE AND IMPORTANCE: Tumoral calcinosis is a rare disorder presenting with tumor-like masses of calcification, usually in soft tissues around large joints. Although this condition has been reported in the spine, this is the first reported instance of this uncommon lesion occurring in the intradural compartment, involving the filum terminale. CLINICAL PRESENTATION: A 55-year-old man presented with back and right leg pain. Initial investigations revealed no cause. A review of his original magnetic resonance imaging scans revealed an intradural calcified mass at L3 level. Surgical exploration was undertaken. INTERVENTION: A L3 laminectomy revealed a calcified mass adherent to the filum terminale. Frozen section from this mass revealed tumoral calcinosis involving the filum terminale. CONCLUSION: This is the first known case of intradural involvement by tumoral calcinosis. This is an uncommon disorder, and a high index of suspicion is required to diagnose the condition, which can recur if incompletely removed.

Underutilization of aspirin persists in US ambulatory care for the secondary and primary prevention of cardiovascular disease.

BACKGROUND: Despite the proven benefits of aspirin therapy in the primary and secondary prevention of cardiovascular disease (CVD), utilization rates of aspirin remain suboptimal in relation to recommendations. We studied national trends of aspirin use among intermediate- to high-risk patients in the US ambulatory care settings and compared the priority given to aspirin versus statins for CVD risk reduction. We also examined patient and health care provider contributors to the underuse of aspirin. METHODS AND FINDINGS: We used the 1993-2003 US National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey to estimate aspirin use by cardiovascular risk. Physician-noted cardiovascular diseases defined high risk. Intermediate risk was defined as having diabetes mellitus or multiple major risk factors. The proportion of patient visits in which aspirin was reported increased from 21.7% (95% confidence interval: 18.8%-24.6%) in 1993-1994 to 32.8% (25.2%-40.4%) in 2003 for the high-risk category, 3.5% (2.0%-5.0%) to 11.7% (7.8%-15.7%) for visits by patients diagnosed with diabetes, and 3.6% (2.6%-4.6%) to 16.3% (11.4%-21.2%) for those with multiple CVD risk factors. Beginning in 1997-1998, statins were prioritized over aspirin as prophylactic therapy for reducing CVD risk, and the gaps remained wide through 2003. In addition to elevated CVD risk, greater aspirin use was independently associated with advanced age, male gender, cardiologist care, and care in hospital outpatient departments. CONCLUSION: Improvements in use of aspirin in US ambulatory care for reducing risks of CVD were at best modest during the period under study, particularly for secondary prevention, where the strongest evidence and most explicit guidelines exist. Aspirin is more underused than statins despite its more favorable cost-effectiveness. Aggressive and targeted interventions are needed to enhance provider and patient adherence to consensus guidelines for CVD risk reduction.

The impact of physiological, therapeutic and psychosocial variables on glycemic control in youth with type 1 diabetes mellitus.

OBJECTIVE: Intensive management of type 1 diabetes mellitus (DM1) in youth is challenging. We evaluated the relative impact of variables related to DM1 among groups of pre/early pubertal, midpubertal and postpubertal youths with DM1. METHODS: In this cross-sectional study of 153 youth with DM1, we ascertained Tanner stage, insulin dose and delivery modality (CSII vs MDI), daily blood glucose monitoring (BGM) frequency, and most recent hemoglobin A1c (HbA1c). We collected questionnaires from patients and their parents on diabetes-specific family conflict and family involvement in diabetes management tasks. We assessed predictors of glycemic control according to pubertal status. RESULTS: Insulin doses increased between pre/ early puberty and midpuberty (p <0.0001); daily BGM frequency (p = 0.02) and family involvement for DM management (p <0.001) were lowest in the postpubertal group. HbA1c was similar among all three puberty groups (8.4+/-1.4). Lower levels of child-reported DM-specific family conflict, more frequent BGM, and CSII use were significantly associated with lower HbA1c (R2 = 0.20, p <0.001). CONCLUSION: Although glycemic control was not significantly worse in midpubertal and post-pubertal patients, family involvement for DM management and adherence to BGM were lower in late adolescence. Interventions to optimize glycemic control may include minimizing DM-specific conflict, increasing BGM frequency, and implementing CSII use.

Community health survey in an urban African-American neighborhood: distribution and correlates of elevated blood pressure.

While considerable improvements have been made over the last 30 years in hypertension (HTN) awareness, treatment, and control, a recent reversal of these trends has been documented with African-American adults, particularly among those continuing to suffer from uncontrolled hypertension and its adverse consequences. This paper presents data from a cross-sectional representative survey of the health status of an urban African-American community. The study was designed in partnership with community leadership to improve HTN care and control. The baseline survey was a face-to-face interview (including blood pressure [BP] measurements) of 2,196 adults residing in randomly selected blocks in the Sandtown-Winchester neighborhood in Baltimore City. These sample data were compared with national data from the NHANES III survey, and demonstrated similar awareness of hypertension. However, hypertension control rates among treated hypertensives were significantly lower in the study community (28%) than in the national survey (44%). Compared with normotensive individuals, those with HTN were significantly older, had less education, were less likely to be employed, and had lower annual incomes. Individuals with HTN were also significantly more likely to rate their health as poor/fair, to report a history of heart disease, stroke, diabetes, kidney disease, obesity, high cholesterol, and lack of exercise, as well as to be at greater risk of alcoholism or alcohol problems. Hypertensive individuals (88% with reported prior history, 12% newly detected) were significantly more likely to have a usual source of care, have seen a health professional in the last 12 months, and to be extremely satisfied with the provider; however, 20% of individuals with hypertension reported no health insurance. These data indicate the need for focused interventions to enhance hypertension maintenance of care and adherence to treatment.

[Primary mesothelioma of the pericardium: a clinical case].

We describe a 33-years-old male patient, presenting with progressive right heart failure. After evaluation, the hypothesis of effusive-constrictive pericarditis was considered. Medical therapy was initiated with no clinical benefit. On the 15th day after admission he was proposed for surgical intervention. The intraoperatory examination revealed a thick pericardium adhering to the epicardium without a clear separation between them. Complete resection was technically impossible. The postoperative course evolved with worsening heart failure and development of renal failure requiring hemodialysis. A diagnosis of primary pericardial mesothelioma was made after histological evaluation. The patient died 8 days after surgery despite all efforts at hemodynamic compensation. Despite its rarity, this diagnosis should be considered in cases with rapid evolution of constrictive or effusive-constrictive pericarditis. The prognosis for pericardial mesothelioma is poor due to its late diagnosis, the difficulty of surgical excision and poor response to radio- or chemotherapy.

[The prescription of treatment and the problem of adherence to the care on the part of the patient].

Poor adherence to treatment contributes significantly to treatment failures in medical care. The extent of the problem and its impact are considerable, by affecting patients, society and the health care system. Studies examining contributing factors have focused on patients' sociodemographic characteristics, features of the treatment regimen and disease state. When viewed in isolation, these variables have little if any descriptive or predictive value. It is difficult to identify which factors contribute to non-adherence, in any particular patient, without carefully interviewing the patient, and the solutions to remove barriers to adherence and to facilitate prescription observations must be individually tailored. Patient's beliefs, expectancies and representations of illness and treatment play a central role in determining the degree of adherence and the level of resistance to educational interventions; for this reason, during the medical interview, the first task is pick-up the cues of patient's representation to identify their features. In this perspective, the appropriate style of interaction is the biopsychosocial approach.

A prospective study of adjustment to hemodialysis.

OBJECTIVE: To examine (a) changes in subjects' self-care self-efficacy over time and (b) the relationship of subjects' self-care self-efficacy with adjustment to hemodialysis. DESIGN: A longitudinal design was used to study changes in self-care self-efficacy and associations between self-care self-efficacy and measures of adjustment: health status, mood distress, symptom distress, dialysis stress, and perceived adherence to fluid restriction. SAMPLE/SETTING: Subjects were recruited from 8 settings in the Northeast where outpatient hemodialysis treatment was administered. Sixty-four subjects were recruited to the study. Twenty-eight subjects completed 3 occasions of data collection. METHODS: Data were collected on three occasions: (a) baseline-within 100 days of beginning treatment; (b) 4 months after beginning treatment; and (c) 8 months after beginning treatment. Eta-squared, a measure of practical significance, is reported for four factors of the self-care self-efficacy measure on each of the three occasions. Associations between self-care self-efficacy and measures of adjustment were examined by means of Pearson correlations. RESULTS: Eta-squared estimates showed generally positive changes occurring over time in subjects' self-care self-efficacy, health status, mood distress, symptom distress, dialysis stress, and perceived adherence to fluid restriction. Changes were more positive at 4-months than at 8-months after enrollment. Significant correlations (p < .05) occurred between self-care self-efficacy and mood states, health status, symptom distress, and perceived adherence to fluid restrictions. Correlations occurred more frequently between self-care self-efficacy and mood states than between self-care self-efficacy and other measures of adjustment. CONCLUSIONS: The study provided pilot data suggesting that hemodialysis patients' self-care self-efficacy and measures of adjustment change over time. Patients who had increased confidence in self-care strategies (self-efficacy) were associated with having more positive mood states, health status, and perceived adherence to fluid restrictions and less symptom distress. Interventions designed to increase patients' self-care self-efficacy may yield positive results. Nurses are in an excellent position to give efficacy enhancing feedback that may promote patients' adjustment.

Telehealth services to improve nonadherence: A placebo-controlled study.

The objective of this study was to test whether a telehealth intervention could improve the compliance with continuous positive airway pressure (CPAP) by patients with sleep apnea. These patients had been nonadherent for the initial 3 months of therapy even after receiving the initial standard and then supplemental audiotaped/videotaped patient education for adhering to CPAP nightly. The materials and methods included a randomized testing of experimental and placebo interventions. Interventions were delivered by nurses to two groups in their homes by telehealth over a 12-week period. The placebo intervention was used to control for Hawthorne effect, time and attention influences and the novelty of having telehealth in the home. Results following the telehealth interventions were that significantly more patients in the experimental group 1 (n = 10) than the placebo group 2 (n = 9) were adhering nightly to CPAP (chi 2 = 4.55, p = 0.033). Group 1 patients reported greater satisfaction with their intervention. However, both groups rated telehealth delivery positively. The mean cost of each 20-minute telehealth visit was 30 dollars while the total cost of the telehealth intervention for each patient was 420 dollars. These costs included telehealth equipment, initial installation, longdistance telephone charges, nurse salary, and intervention materials. Conclusions are that telehealth interventions are a potentially cost-effective service for increasing adherence to prescribed medical treatments. Replication studies with large samples and in other clinical groups are recommended.

Intensive telephone follow-up to a hospital-based disease management model for patients with diabetes mellitus.

The objective of this study was to evaluate the value of an intensive telephone follow-up as an additional component of a diabetes disease management program already shown to be effective in improving glycemic control, adherence with American Diabetes Association (ADA) standards of care, and health-related quality of life (HRQOL). The study involved a randomized controlled trial. The intervention group received a series of 12 weekly phone calls reinforcing base education and self-management skills. Five hundred and seven consenting patients, age 18 years or older, with type 1 or type 2 diabetes mellitus referred to the hospital- based disease management program who had telephones and were able to complete surveys in English or Spanish were enrolled. Outcomes were evaluated at 3 and 12 months follow- up. Adherence to ADA standards of care, specifically annual eye exams, physician foot exams, foot self-exams, and pneumonia vaccination were significantly better with the added telephone intervention, but there were no differences between the groups on glycemic control, HRQOL, or patient satisfaction. The effectiveness of the disease management program was replicated with sustained improvement in glycemic control, HRQOL, and adherence to ADA standards. The additional telephone intervention further improved adherence to ADA guidelines for self-care and medical care but did not affect glycemic control or HRQOL.

Is default from colposcopy a problem, and if so what can we do? A systematic review of the literature.

It has been reported that many women referred to outpatient colposcopy clinics fail to attend for their appointments. The aim of this paper is to search the literature to assess the extent of default from colposcopy and to identify interventions, suitable for implementation within primary care, to reduce the proportion of women defaulting. Searches were performed on MEDLINE, PsychLIT, Bids and Cancerlit from 1986 to September 1997 using the terms colposcopy or cervical/Pap smear in association with default, non-attendance, adherence, patient compliance, treatment refusal, patient dropouts, attendance, barriers or intervention. The inclusion criteria for primary papers were that they contained data that enables the calculation of default rates for colposcopy or the results of interventions aimed at improving the default rates. Thirteen publications describing default rates and four describing interventions were included as primary papers. Combining the data from these studies suggests default rates of 3%, 11%, and 12% for assessment/treatment visits, first review, and second review respectively. The intervention studies suggested a need to tailor the intervention to the population and the type of information to suit the individual. Varying definitions make comparison of default rates difficult, and the use of a crude non-attendance rate may result in an overestimate of default rates. The vast majority of women invited to colposcopy eventually attend. It is questionable if there is a need for interventions to increase compliance. Where necessary, greater cooperation across the primary/secondary care interface and use of the extended primary care team may be a more cost-effective means of increasing compliance.

What is the impact of early rheumatoid arthritis on the individual?

Rheumatoid arthritis has a significant impact on patients' physical, emotional and social functioning that often occurs very early in the disease with the onset of symptoms. Patients therefore come to their consultation with the rheumatologist, having often experienced these symptoms over a period of some months, with specific expectations (for reassurance and diagnosis) and their own understanding and beliefs about the aetiology and prognosis of their symptoms. Information and advice given by rheumatologists will be rejected by patients if it cannot be accommodated within these lay beliefs. The diagnosis itself can cause a variety of reactions, including relief, disbelief, anger, fear and devastation. Following diagnosis, patients are faced with the problems of adapting to a new self-concept, managing their symptoms and trying to assimilate the large amount of information that they are given about their disease, its treatment, preferred health behaviours, prognosis and so on. There are a number of ways in which health professionals can reduce this impact in early disease. Eliciting patients' lay beliefs about the cause of their symptoms will ensure that information given in the consultation is relevant to individual patients and is presented in a way that has meaning for them. Determining patients' expectations of the rheumatologist will ensure that patients' needs for information and reassurance are met and that unrealistic or inappropriate expectations can be discussed and re-negotiated. Understanding patients' attitudes towards treatment interventions will inform shared clinical decision-making and promote adherence. Obtaining this information in the context of a time-limited consultation can be assisted by the use of validated clinical tools, presented as self-completed questionnaires. Further research is needed to determine the content, frequency, timing and methodology of educational interventions in early rheumatoid arthritis and to improve the understanding of the complex interaction between lay beliefs and disease outcome.

Prenatal screening for infectious diseases and opportunities for prevention.

OBJECTIVE: To characterize adherence with recommendations for prenatal infectious disease screening and missed opportunities for prevention of congenital and perinatal infections. METHODS: Demographic, prenatal, and peripartum information was abstracted from labor and delivery records of a random, stratified sample of live births in 1998 and 1999 to residents of eight active surveillance areas. Adherence with prenatal screening recommendations was evaluated for hepatitis B, syphilis, rubella, human immunodeficiency virus (HIV), and group B streptococcus (GBS). Characteristics of missed opportunities for disease prevention were assessed by univariate and multivariable analysis to account for survey design. RESULTS: Prenatal screening rates for hepatitis B surface antigen (HBsAg) (96.5%), syphilis (98.2%), and rubella (97.3%) were high. Areas of excess syphilis morbidity did not adhere to recommendations for third-trimester retesting. Testing rates for HIV (57.2%) and GBS (52.0%) were lower and had wide geographic variation. Postpartum rubella vaccination was documented for only 65.7% of rubella-susceptible women. Inadequate prenatal care was the single strongest predictor of missed opportunities for prenatal testing (relative risk 14.6; 95% confidence interval 6.3, 33.7). Blacks were less likely than whites to receive adequate prenatal care and prenatal tests, more likely to test positive for HBsAg and syphilis, and less likely to receive recommended prevention interventions such as postpartum rubella vaccination for susceptible women. CONCLUSIONS: Adherence to both long-standing and more recent recommendations for congenital and perinatal disease prevention can be improved, thus perhaps reducing racial disparities in the use of prenatal screening and appropriate prevention interventions.

Health behaviors and pharmacotherapy.

OBJECTIVE: To review factors related to health beliefs and behavior that affect treatment adherence, and to suggest behavioral strategies for improving adherence. DATA SOURCES: We conducted MEDLINE and PSYHLIT (January 1966-October 1997) searches of English-language literature pertaining to behavioral medicine and health behavior as they relate to treatment adherence. Additional articles from these sources and reference texts were identified. DATA EXTRACTION: All articles and chapters identified were considered. The most pertinent information, as judged by the authors, was selected for discussion. DATA SYNTHESIS: Health care is moving into an era of disease management, and practitioners will be called upon to help patients change health-related behaviors and to improve adherence to treatment. Fundamental to this new paradigm of practice is an understanding of behavior, its relationship to health, and methods by which it can be altered. Current concepts of health behavior have been heavily influenced by social learning theory, self-efficacy theory, and a biopsychosocial view of health and disease. The intent of this review is to provide clinicians with an overview of factors that affect health-related behaviors, as well as suggestions for helping patients to improve them. As illustrations, behavioral interventions used in patients with asthma are presented. CONCLUSIONS: Adherence to treatment recommendations depends on a complex interplay of many psychological variables. An understanding of these factors, and how behavioral techniques may be used, will help healthcare providers to assist patients in improving adherence.

Characteristics of patients adhering to a hospital's no-smoking policy.

OBJECTIVES: The purpose of this paper is to examine the characteristics of smokers who adhere to a hospital smoking ban, compared to those who do not. DESIGN: The data presented in this paper are baseline and discharge survey data collected among hospitalized smokers. SETTING: This study was conducted in two teaching hospitals in a northeastern city. PATIENTS/PARTICIPANTS: The subjects were 358 smokers who participated in a larger smoking intervention trial. MAIN RESULTS: Seventy-six percent of the subjects reported adhering to the smoke-free policy during their hospital stay. In a multivariate model, demographic factors that predicted adherence included being older, having shorter length of stay, not reporting recreational drug use in the previous 12 months, and not having alcohol-related problems. Smoking history variables that predicted adherence included having had at least 24 h of abstinence in the 7 days prior to hospitalization; self-efficacy variables (e.g., confidence in ability to quit smoking in 1 month and less anticipated difficulty refraining from smoking during hospitalization) also predicted adherence. CONCLUSIONS: Understanding the factors that predict adherence to health care policies can provide useful information for health promotion interventions in a medical setting. The implications of these findings are discussed.

Caring for others: Internet video-conferencing group intervention for family caregivers of older adults with neurodegenerative disease.

PURPOSE: The aim of this pilot feasibility study was to evaluate the effects of an innovative, Internet-based psychosocial intervention for family caregivers of older adults with neurodegenerative disease. DESIGN AND METHODS: After receiving signed informed consent from each participant, we randomly assigned 66 caregivers to an Internet-based intervention or to a no-intervention control group. The intervention group received computers and training in order to access a password-protected Web site with links to information, e-mail, and threaded discussion. Unique to the Web site was a video-conferencing link that supported caregivers' participation in a 10-session, manual-guided psychosocial support group, followed by 12 additional online sessions facilitated by a group member. Participants completed health-status and stress-response measures at baseline and 6-month follow-up. RESULTS: Content analysis of archived video sessions showed (a) reliable adherence to the manual-guided support-group intervention and (b) online group discussion themes similar to those in face-to-face caregiver support groups. Analyses of stress-response outcome data showed significant between-group differences, with the intervention group experiencing a decline in stress compared with an escalation in stress for the control group. IMPLICATIONS: Despite the limitations of this pilot study in terms of limited sample size and 54% dropout of control participants at 6-month follow-up, the results provide preliminary supportive evidence for a technology-based psychosocial intervention for family caregivers of individuals with neurodegenerative disease.

Psychosocial and cognitive factors associated with adherence to dietary and fluid restriction regimens by people on chronic haemodialysis.

BACKGROUND: Failure by people on chronic haemodialysis to adhere adequately to dietary and fluid restrictions can have serious medical consequences. Numerous psychosocial factors possibly associated with adherence have been investigated in previous research. However, most previous studies have examined one or a few variables in isolation, and have tended to focus on sociodemographic variables not easily amenable to intervention. Much previous work has tended to ignore potential differences in adherence between male and female dialysands. METHODS: Sociodemographic and psychosocial factors associated with adherence to dietary and fluid restrictions were investigated in 45 people on haemodialysis attending one renal unit, excluding those with a residual urine volume > 500 ml/day. Multiple regression analyses were used to estimate the contribution to adherence of a range of variables, including gender, age, duration of dialysis, affective disturbance, past psychiatric history, health locus of control, social adjustment and social supports. RESULTS: Adherence to diet (measured by predialysis serum potassium) and to fluid restriction (interdialysis weight gain) were not linked, and had different psychosocial correlates. Regression models of four different aspects of adherence revealed very distinct psychosocial correlates, with contributions to adherence from complex interactions between psychosocial and cognitive variables, notably gender, age, social adjustment, health locus of control, and depression. CONCLUSIONS: The findings cast doubt on the results of many previous studies which have used simple models of adherence. Adherence is likely to be influenced in a complex manner by multiple factors including age, gender, locus of control, social adjustment, and past psychiatric history.
