Preferences for medical collaboration: patient-physician congruence and patient outcomes

Patient and physician beliefs about control over health: association of symmetrical beliefs with medication regimen adherence

BACKGROUND

Past work suggests that the degree of similarity between patient and physician attitudes may be an important predictor of patient-centered outcomes.

OBJECTIVE

To examine the extent to which patient and provider symmetry in health locus of control (HLOC) beliefs was associated with objectively derived medication refill adherence in patients with co-morbid diabetes mellitus (DM) and hypertension (HTN).

PARTICIPANTS

Eighteen primary care physicians at the VA Iowa City Medical Center and affiliated clinics; 246 patients of consented providers with co-morbid DM and HTN.

DESIGN

Established patient-physician dyads were classified into three groups according to the similarity of their HLOC scores (assessed in parallel). Data analysis utilized hierarchical linear modeling (HLM) to account for clustering of patients within physicians.

MAIN MEASURES

Objectively derived medication refill adherence was computed using data from the VA electronic pharmacy record; blood pressure and HgA1c values were considered as secondary outcomes.

KEY RESULTS

Physician-patient dyads holding highly similar beliefs regarding the degree of personal control that individual patients have over health outcomes showed significantly higher overall and cardiovascular medication regimen adherence (p = 0.03) and lower diastolic blood pressure (p = 0.02) than in dyads in which the patient held a stronger belief in their own personal control than did their treating physician. Dyads in which patients held a weaker belief in their own personal control than did their treating physician did not differ significantly from symmetrical dyads. The same pattern was observed after adjustment for age, physician sex, and physician years of practice.

CONCLUSIONS

These data are the first to demonstrate the importance of attitudinal symmetry on an objective measure of medication adherence and suggest that a brief assessment of patient HLOC may be useful for tailoring the provider's approach in the clinical encounter or for matching patients to physicians with similar attitudes towards care.

[Patient satisfaction with the patient-doctor relationship measured using the questionnaire (PDRQ-9)]

OBJECTIVE

To describe patient satisfaction of their relationship with the family physician, using the PDRQ-9 questionnaire and assess its psychometric properties.

DESIGN

Cross-sectional study.

SETTING

Six Primary Care Health centres in the Community of Madrid, Spain.

PARTICIPANTS

Four hundred and fifty one patients randomly selected from those who had just visited their family physician.

INTERVENTIONS

Interviews were carried out to collect demographic characteristics, health needs, the accessibility to the service, and the socioeconomic situation of the subjects.

MEASUREMENTS

The PDRQ-9 responses were collected and a synthetic satisfaction index was constructed. A multivariable model was designed to explain differences in satisfaction.

RESULTS

The mean satisfaction index was 4.41 (95% CI: 4.33-4.48) on a scale of 1 (the worst) to 5 (the best satisfaction possible), with a median of 4.78 (interquartile range 4.00-5.00). Four of every 10 subjects expressed the maximum possible satisfaction ("ceiling effect"). A single factor explained 75.3% of the variance, with a Cronbach alpha value of 0.952. Age (OR 1.03, 95% CI: 1.02-1.05) and living in rural areas (OR 1.44, 95% CI: 0.94-2.20) were associated with above average satisfaction.

CONCLUSIONS

Primary care users feel their relationship with their family physicians are very satisfactory, particularly in those who are older and who live in rural areas. The PDRQ-9 questionnaire shows a high internal consistency, but it is not good enough to discriminate in the upper part of the scale.

Comparison of monthly ibandronate versus weekly risedronate in preference, convenience, and bone turnover markers in Korean postmenopausal osteoporotic women

Patient preferences, convenience, and bone turnover markers were evaluated for the monthly ibandronate over the weekly risedronate regimen in Korean postmenopausal osteoporotic women. This was a 6-month, prospective, randomized, open-label, multicenter study with a two-period and two-sequence crossover treatment design. After a 30-day screening period, eligible participants with postmenopausal osteoporosis were randomized to receive either monthly oral ibandronate 150 mg for 3 months followed by weekly oral risedronate 35 mg for 12 weeks (sequence A) or the same regimen in reverse order (sequence B). Patient preference and convenience were evaluated by questionnaire. The changes in serum C-telopeptide after 3 months of treatment were analyzed. A total of 365 patients were enrolled in this study (sequence A 182, sequence B 183). Of patients expressing a preference (83.4%), 74.8% preferred the monthly ibandronate regimen over the weekly regimen (25.2%). More women stated that the monthly ibandronate regimen was more convenient (84.2%) than the weekly regimen (15.8%). There was no significant difference in the change in bone turnover marker between the two treatments. The two regimens were similarly tolerable. There were fewer adverse events in the monthly ibandronate group compared to the weekly risedronate group in terms of gastrointestinal side effects (nausea and abdominal distension). This study revealed a strong preference and convenience for monthly ibandronate over weekly risedronate in Korean postmenopausal osteoporotic women. There was no significant difference in change of bone turnover marker and safety profile between the two regimens.

Perception of head and neck cancer quality of life within the medical world: a multicultural study

BACKGROUND

Physician's perception of quality of life of patients with cancer is unclear. No reports have evaluated its influence on patient management.

METHODS

Five hundred otolaryngologists completed a questionnaire regarding the quality of life of patients with head and neck cancer.

RESULTS

Seventy-eight percent of responders thought that quality of life must be considered when choosing treatment, even if this meant decreased survival. Seventy-five percent thought it justified to withhold curative treatment if this would lead to impaired quality of life. Pain and breathing were the most important symptoms to consider. The perception was worse for physicians practicing in Latin culture, working in private practice, or with no personal acquaintance with a head and neck cancer victim and was better after radiotherapy than after surgery and chemotherapy.

CONCLUSION

Quality of life is important for physicians and is considered as essential as survival by many physicians. The perception of patient's quality of life influences the treatment choice.

The effect of physician-patient collaboration on patient adherence in non-psychiatric medicine

OBJECTIVE

Factors contributing to treatment adherence are poorly understood but the physician-patient interaction is one factor that is known to affect patient adherence.

METHODS

This meta-analysis systematically reviewed the published literature to determine the magnitude of the relationships between physician-patient collaboration and patient adherence.

RESULTS

A statistically significant weighted mean effect size of M(d)=0.145 from 48 published studies indicated better physician-patient collaboration is associated with better patient adherence. The relationship between collaboration and adherence was sustained for pediatric and adult populations, chronic and acute conditions, and primary physician and specialists.

CONCLUSION

These results emphasize the need for physician-patient collaboration within the medical consultation.

PRACTICE IMPLICATIONS

The inclusion of the patient's perspective during the consultation is essential to obtaining cooperation once the patient has left the physician's office.

An exploratory mixed-method study to determine factors that may affect satisfaction levels of athletes receiving chiropractic care in a nonclinic setting

OBJECTIVES

The objectives of this study were to determine factors that may affect satisfaction levels of participants in a nonclinic (sport) setting through participant observation and participation. Factors associated with general satisfaction (observed) were determined along with a participant demographic profile, participant knowledge about chiropractic, and satisfaction with treatment received from a chiropractic student. Thereafter, the relationships between the demographic factors, participant knowledge, and participant general satisfaction were determined. Lastly, factors affecting satisfaction levels were compared between the participants and the observers.

METHODS

An exploratory mixed-method observational study that compared results reported by 30 participants and 2 observers, regarding the treatment process, by completion of a self-administered questionnaire. Statistical significance was set at P less than or equal to .05.

RESULTS

Of the 30 participants, 83.3% were South African, 90% were white, and 63.3% were male, with a mean age of 35.6 years, who reported they were very satisfied with chiropractic care (P = .229). The only factor to produce a significant difference between participants and observers was communication (P = .082 with Spearman = .332).

CONCLUSION

In this study, communication had the greatest impact; therefore, it is suggested that positive verbal and nonverbal communication be emphasized in the training of future chiropractic professionals.

A 41-year-old African American man with poorly controlled hypertension: review of patient and physician factors related to hypertension treatment adherence

Mr R is an African American man with a long history of poorly controlled hypertension and difficulties with adherence to recommended treatments. Despite serious complications such as hypertensive emergency requiring hospitalization and awareness of the seriousness of his illness, Mr R says at times he has ignored his high blood pressure and his physicians' recommendations. African Americans are disproportionately affected by hypertension and its complications. Although most pharmacological and dietary therapies for hypertension are similarly efficacious for African Americans and whites, disparities in hypertension treatment persist. Like many patients, Mr R faces several barriers to effective blood pressure control: societal, health system, individual, and interactions with health professionals. Moreover, evidence indicates that patients' cognitive, affective, and attitudinal factors and the patient-physician relationship play critical roles in improving outcomes and reducing racial disparities in hypertension control.

Improving compliance and persistence to adjuvant tamoxifen and aromatase inhibitor therapy

Better compliance and persistence with therapy are associated with improved patient outcomes. As more and more patients survive breast cancer, compliance with adjuvant therapy becomes increasingly important. In clinical trials, compliance with adjuvant endocrine therapy among women with breast cancer is usually high. Retrospective analyses of databases and medical records from clinical practice, insurance databases of prescription refills, and survey data show a significant decrease in persistence after 12 months of therapy. With ongoing therapy, a further decline in persistence of up to 50% has been reported. A consistent methodology is needed to measure patient behavior and identify patients who are not adhering to therapy. Promising strategies for enhancing adherence to treatment in clinical practice include improving access to health care, increasing patient satisfaction, managing side effects, patient education, and better communication between the patient and health care provider. Positive relationships between patients and their health care providers, and frequent monitoring and feedback, may be most effective. While the lack of conformity across studies in measuring makes cross-study comparisons difficult, this review evaluates the available data regarding compliance and persistence with adjuvant endocrine therapies for breast cancer (tamoxifen and aromatase inhibitors) and presents strategies for improving adherence.

Physician beliefs and behaviors related to glaucoma treatment adherence: the Glaucoma Adherence and Persistency Study

PURPOSE

Patient adherence with topical glaucoma therapy is recognized as suboptimal. Though some studies have associated physician/patient interaction with adherence, little systematic research has explored the ophthalmologist's perspective of this interaction. Telephone interviews with physicians treating glaucoma were conducted to ascertain the extent to which multivariate analysis of physician demographics, beliefs, and behaviors could reveal differences potentially relevant to future adherence with topical glaucoma therapy for primary open-angle glaucoma, in conjunction with other phases of the Glaucoma Adherence and Persistency Study (GAPS).

METHODS

Structured interviews were conducted with 103 ophthalmologists treating significant numbers of primary open-angle glaucoma patients in a national managed care network. To the maximum extent possible, eligible patients of physicians interviewed were included in the other GAPS phases (claims analysis, patient surveys, and medical chart reviews).

RESULTS

Physicians reported a wide range of beliefs and behaviors regarding patients' medication adherence, but beliefs and behaviors were linked. The segmentation analysis yielded 3 clusters of physicians, which we have described on the basis of their predominant beliefs as "reactives," "skeptics," and "idealists." The "idealists," though the smallest group, more often reported beliefs and behaviors that may be more positively associated with patient adherence, especially in the context of other GAPS findings.

CONCLUSIONS

Physician vigilance for opportunities to detect and address nonadherence is suggested, as is interventional research on the basis of the constructs identified.

Medication adherence self-report instruments: implications for practice and research

BACKGROUND

After an acute cardiac event, adhering to recommendations for pharmacologic therapy is important in achieving optimal health outcomes. Considering the impressive evidence base for cardiovascular pharmacotherapy, strategies for promoting adherence are less well developed. Furthermore, accessing reliable, valid, and cost-effective mechanisms of monitoring adherence in the research and clinical settings is challenging.

AIM

The aim of this article was to review published self-report measures assessing and monitoring medication adherence in cardiovascular disease and provide recommendations for research into medication adherence.

METHODS

The electronic databases CINAHL, Medline, and Science Direct were searched using the key search terms medication adherence and/or compliance, cardiovascular, self-report measures, and questionnaires. The World Wide Web was searched using the Google and Google Scholar search engines, and reference lists of retrieved documents were reviewed. The search strategy was verified by a health librarian. Instruments were included if they specifically addressed medication adherence as a discrete construct rather than a disease-specific or a generic health status measurement.

FINDINGS

Despite of the problems with medication adherence identified in the literature, only 7 instruments met the search criteria. There was limited use of instruments across studies and settings to enable comparison across populations and extensive psychometric evaluation.

CONCLUSIONS

Medication adherence is a complex, multifaceted construct dependent on a range of physical, social, economic, and psychological considerations. In spite of the importance of adherence in ensuring optimal cardiovascular outcomes, conceptual underpinnings and methods of assessing medication adherence require further discussion and debate.

The effects of socioeconomic status on participation in care among middle-aged and older adults

OBJECTIVE

This study assesses the effects of socioeconomic status (education and poverty) on seeking health information and subsequent use of this information during the medical encounter.

METHOD

Data on 19,944 adults (aged 45 and older) were drawn from the 2000-2001 Household Component of the Community Tracking Study, a nationally representative survey of non-institutionalized individuals.

RESULTS

Higher levels of education were associated with a greater likelihood of seeking health information and mentioning information to physicians. The poor and near poor were less likely to seek health information, but only the near poor were significantly less likely to mention information to the physician.

DISCUSSION

These findings underscore the importance of education in the acquisition and use of health information among middle-aged and older adults.

Sustaining a healthy work force in the 21st century--a model for collaborating through reciprocation

Occupational health nurses are positioned to restore and maintain worker health, well-being, and safety, thereby increasing productivity. A model of practice is needed that provides a comprehensive worker-environment perspective. A model that incorporates reciprocation and collaboration increases workers' engagement in their own health action plan. It empowers workers and provides a broader multidimensional perspective on factors affecting or influencing their health. The Reciprocation Model has been designed using the nursing process; it incorporates reciprocation and collaboration to assist occupational health nurses improve or maintain worker health and safety, as well as achieve corporate goals of reducing on-the-job lost time and increasing productivity.

When doctors disagree: a qualitative study of doctors' and parents' views on the risks of childhood food allergy

OBJECTIVE

To examine the views of doctors which underpin clinical practice variation concerning an uncertain health risk, and the views of parents who had sought advice from these doctors, using the example of childhood food allergy.

STUDY DESIGN

Qualitative study involving in-depth interviews and participant observation over 16 months. Focus groups and consultation audio-recordings provided corroborative data.

SETTING

Three specialist allergy clinics located in one metropolitan area.

PARTICIPANTS

Eighteen medical specialists and trainees in allergy, and 85 parents (from 69 families) with food allergic children.

RESULTS

Doctors expressed a spectrum of views. The most divergent views were characterized by: scientific scepticism rather than precaution in response to uncertainty; emphasis on quantifiable physical evidence rather than parental histories; professional roles as providers of physical diagnosis and treatment rather than of information and advocacy; libertarian rather than communitarian perspectives on responsibility for risk; and values about allergy as a disease and normal childhood. Parents held a similar, but less divergent range of views. The majority of parents preferred more moderate doctors' views, with 43% (30 of 69) of families expressing their dissatisfaction by seeking another specialist opinion. Many were confused by variation in doctors' opinions, preferring relationships with doctors that recognized their concerns, addressed their information needs, and confirmed that they were managing their child's allergy appropriately.

CONCLUSIONS

In uncertain clinical situations, parents do not expect absolute certainty from doctors; inflexible certainty may not allow parental preferences to be acknowledged or accommodated, and is associated with the seeking of second opinions.

Bisphosphonates in the management of postmenopausal osteoporosis--optimizing efficacy in clinical practice

Nitrogen-containing bisphosphonates are potent inhibitors of osteoclastic bone resorption. With their individually proven efficacy to significantly reduce the incidence of vertebral and/or non-vertebral fractures and with their overall beneficial safety profile, alendronate, ibandronate, risedronate, and zoledronate are considered today a treatment of first choice in postmenopausal osteoporosis. However, treatment effects in an individual patient and cost-effectiveness in public health perspective are vitally dependent on the long-term patient adherence as well as on compliance and persistence. As compliance and persistence with daily oral bisphosphonates are shown to be suboptimal in many patients, leading to an increased fracture incidence in non-compliant patients, there is a need to improve overall adherence for bisphosphonate treatment in order to achieve maximum treatment effects. One option is to extend dosing intervals to weekly (alendronate, risedronate) or monthly (ibandronate) oral regimens. Less frequent oral regimens are generally preferred by majority of patients. Another alternative is intravenous, instead of oral application (ibandronate, zoledronate). Treatment acceptance could be further improved by IV bisphosphonates with their benefit of only quarterly, or even once-yearly, application. Treatment decisions should be based on anti-fracture efficacy data first. In addition, to ensure best possible patient adherence and maximum treatment benefits, physicians should consider individual patient conditions affecting compliance and persistence as well as patient preferences.

"Surgery is certainly one good option": quality and time-efficiency of informed decision-making in surgery

BACKGROUND

Informed decision-making has been widely promoted in several medical settings, but little is known about the actual practice in orthopaedic surgery and there are no clear guidelines on how to improve the process in this setting. This study was designed to explore the quality of informed decision-making in orthopaedic practice and to identify excellent time-efficient examples with older patients.

METHODS

We recruited orthopaedic surgeons, and patients sixty years of age or older, in a Midwestern metropolitan area for a descriptive study performed through the analysis of audiotaped physician-patient interviews. We used a valid and reliable measure to assess the elements of informed decision-making. These included discussions of the nature of the decision, the patient's role, alternatives, pros and cons, and uncertainties; assessment of the patient's understanding and his or her desire to receive input from others; and exploration of the patient's preferences and the impact on the patient's daily life. The audiotapes were scored with regard to whether there was a complete discussion of each informed-decision-making element (an IDM-18 score of 2) or a partial discussion of each element (an IDM-18 score of 1) as well as with a more pragmatic metric (the IDM-Min score), reflecting whether there was any discussion of the patient's role or preference and of the nature of the decision. The visit duration was studied in relation to the extent of the informed decision-making, and excellent time-efficient examples were sought.

RESULTS

There were 141 informed-decision-making discussions about surgery, including knee and hip replacement as well as wrist/hand, shoulder, and arthroscopic surgery. Surgeons frequently discussed the nature of the decision (92% of the time), alternatives (62%), and risks and benefits (59%); they rarely discussed the patient's role (14%) or assessed the patient's understanding (12%). The IDM-18 scores of the 141 discussions averaged 5.9 (range, 0 to 15; 95% confidence interval, 5.4 to 6.5). Fifty-seven percent of the discussions met the IDM-Min criteria. The median duration of the visits was sixteen minutes; the extent of informed decision-making had only a modest relationship with the visit duration. Time-efficient strategies that were identified included use of scenarios to illustrate distinct choices, encouraging patient input, and addressing primary concerns rather than lengthy recitations of pros and cons.

CONCLUSIONS

In this study, which we believe is the first to focus on informed decision-making in orthopaedic surgical practice, we found opportunities for improvement but we also found that excellent informed decision-making is feasible and can be accomplished in a time-efficient manner.

Physician-Identified Factors Affecting Patient Participation in Reaching Treatment Decisions

Purpose

Cancer physicians report high comfort with shared decision making but a lower frequency of using this approach in practice. Information regarding physicians’ perceptions of what helps and what hinders patient involvement in decision making may facilitate understanding of this discrepancy.

Methods

We surveyed 604 Australian cancer physicians treating breast, colorectal, gynecologic, hematologic, or urologic cancer to investigate barriers and facilitators to reaching treatment decisions with their patients and their support of strategies to encourage patient involvement and reflection on treatment options. Factor analysis and regression analyses were used to investigate relationships between variables and identify predictors of greater reporting of barriers to sharing treatment decisions with patients.

Results

Insufficient information at the first consultation (28.9%) and insufficient time (28.4%) were the most frequently reported barriers to reaching treatment decisions with patients. Multivariate analysis revealed that less experienced physicians more commonly reported system barriers (P = .00). Patients trusting their physician and being accompanied at the consultation were most helpful to reaching a treatment decision. Providing written information about treatment options, making a further appointment to reach a decision, encouraging the patient to speak with their family physician and treatment team, and the presence of a third person during the consultation were felt to encourage involvement and reflection on treatment decisions.

Conclusion

Cancer physicians experience difficulties when reaching treatment decisions with their patients. Interventions and strategies that physicians support are required to enhance patient involvement in reaching a treatment decision.

Patient-provider perceptions of diabetes and its impact on self-management: a comparison of African-American and White patients

AIMS

To compare patient-provider differences in diabetes-related perceptions between African-American and White patients and to examine its association with self-care behaviours.

METHODS

One hundred and thirty patient-provider pairs were recruited from the greater Detroit area. Patients and providers completed a survey assessing perceptions about diabetes-related concepts and demographic background. The Diabetes Semantic Differential Scale was used to measure diabetes-related perceptions. Patients also reported the frequency of performing self-care behaviours, including following a healthy eating plan, engaging in physical activity, blood glucose monitoring, and taking medication and/or insulin.

RESULTS

There were a greater number of patient-provider differences in diabetes-related perceptions for the African-American patients (nine of 18 concepts) compared with the White patients (four of 18 concepts). Stepwise regression analyses found patients' semantic differential scores to be significantly associated with five self-care behaviours for African-American patients and two self-care behaviours for White patients. Providers' semantic differential scores emerged as predictors of self-care behaviours for African-American patients, but not for White patients.

CONCLUSIONS

Our findings suggest that compared with White patients, African-Americans differ in a greater number of diabetes-related perceptions than their providers. Patients' and providers' perceptions of diabetes care concepts have a significant impact on a greater number of self-care behaviours for African-American patients than White patients.

Patient preference in the management of postmenopausal osteoporosis with bisphosphonates

The leading treatments for postmenopausal osteoporosis are the nitrogen-containing bisphosphonates, which are required long term for optimal benefit. Oral bisphosphonates have proven efficacy in postmenopausal osteoporosis in clinical trials, but in practice the therapeutic benefits are often compromised by patients' low adherence. Nonadherence to bisphosphonate therapy negatively impacts outcomes such as fracture rate; fractures are in turn associated with decreased quality of life. The most common reason cited by patients for their nonadherence is that the strict dosing instructions for bisphosphonates are difficult to follow. One aspect of bisphosphonate administration that can be changed is dosing frequency and several studies have evaluated patient preferences for different dosing schedules. Studies have shown a preference for a weekly bisphosphonate regimen versus daily dosing and it has been demonstrated that this preference for reduced dosing frequency impacts on adherence. Ibandronate is the first nitrogen-containing oral bisphosphonate for osteoporosis that can be administered in a monthly regimen and two robust clinical studies demonstrated a strong patient preference for this monthly regimen versus a weekly regimen. It is important that physicians consider patient preference when prescribing treatment for osteoporosis to ensure that the disease is effectively managed for the long-term benefit of the patient.

Treatment preference for monthly oral ibandronate and weekly oral alendronate in women with postmenopausal osteoporosis: A randomized, crossover study (BALTO II)

OBJECTIVES

Patient preference strongly influences long-term medication use in chronic diseases such as postmenopausal osteoporosis.

METHODS

This 6-month, open-label, crossover, international study randomized 350 women with postmenopausal osteoporosis to monthly oral ibandronate 150mg for 3months followed by weekly alendronate 70mg for 12weeks, or vice versa.

RESULTS

Of patients expressing a preference (93.1%), more preferred the monthly ibandronate regimen (70.6%) than the weekly alendronate regimen (29.4%). The monthly ibandronate preference rate was statistically significant (P<0.0001). The most common reasons for ibandronate preference were ease of staying on treatment long-term (81.5%) and better lifestyle fit (75.4%). More women found the monthly ibandronate regimen more convenient (76.6%) than the weekly alendronate regimen (23.4%). The monthly ibandronate convenience rate was statistically significant (P<0.0001). The safety profiles of the two regimens were similar.

CONCLUSION

The strong patient preference for monthly ibandronate over weekly alendronate replicates previous study findings and may lead to improved treatment adherence in women with postmenopausal osteoporosis.

Patient and physician attitudes in the health care context: attitudinal symmetry predicts patient satisfaction and adherence

BACKGROUND

There is increasing interest in the role that patient and physician health-related attitudes may play in predicting patient outcomes.

PURPOSE

This study examined the similarity of the attitudes held by patients and their physicians about the patient role in health care delivery and its relationship to patient outcomes.

METHODS

Participants were 16 primary care physicians from a single academic medical center and 146 patients who had been seen by their respective physician at least twice during the prior 6 months. Physicians and patients completed two measures reflecting healthcare-related attitudes: the Multidimensional Health Locus of Control questionnaire and the Patient-Practitioner Orientation Scale (PPOS). Patients also completed measures of satisfaction and adherence.

RESULTS

Analyses were conducted using hierarchical linear modeling with patients clustered within physicians. Degree of symmetry on internal health locus of control was positively associated with both patient adherence, F(2, 131) = 3.75, p = .03, and satisfaction, F(2, 133) = 7.16, p = .01. Degree of similarity on the Information/Power Sharing subscale of the PPOS was not positively associated with adherence or satisfaction.

CONCLUSIONS

These data suggest that patients who are more similar in attitude to their physicians as indicated by internal health locus of control scores (but not PPOS scores) are more satisfied with their medical care and more adherent with treatment recommendations than patients who are less internally focused than their physicians.

The context influences doctors' support of shared decision-making in cancer care

Most cancer patients in westernised countries now want all information about their situation, good or bad, and many wish to be involved in decision-making. The attitudes to and use of shared decision-making (SDM) by cancer doctors is not well known. Australian cancer clinicians treating breast, colorectal, gynaecological, haematological, or urological cancer were surveyed to identify their usual approach to decision-making and their comfort with different decision-making styles when discussing treatment with patients. A response rate of 59% resulted in 624 complete surveys, which explored usual practice in discussing participation in decision-making, providing information, and perception of the role patients want to play. Univariate and multivariate analyses were performed to identify predictors of use of SDM. Most cancer doctors (62.4%) reported using SDM and being most comfortable with this approach. Differences were apparent between reported high comfort with SDM and less frequent usual practice. Multivariate analysis showed that specialisation in breast or urological cancers compared to other cancers (AOR 3.02), high caseload of new patients per month (AOR 2.81) and female gender (AOR 1.87) were each independently associated with increased likelihood of use of SDM. Barriers exist to the application of SDM by doctors according to clinical situation and clinician characteristics.

Physicians' communication and perceptions of patients: is it how they look, how they talk, or is it just the doctor?

Although physicians' communication style and perceptions affect outcomes, few studies have examined how these perceptions relate to the way physicians communicate with patients. Moreover, while any number of factors may affect the communication process, few studies have analyzed these effects collectively in order to identify the most powerful influences on physician communication and perceptions. Adopting an ecological approach, this investigation examined: (a) the relationships of physicians' patient-centered communication (informative, supportive, partnership-building) and affect (positive, contentious) on their perceptions of the patient, and (b) the degree to which communication and perceptions were affected by the physicians' characteristics, patients' demographic characteristics, physician-patient concordance, and the patient's communication. Physicians (N=29) and patients (N=207) from 10 outpatient settings in the United States participated in the study. From audio-recordings of these visits, coders rated the physicians' communication and affect as well as the patients' participation and affect. Doctors were more patient-centered with patients they perceived as better communicators, more satisfied, and more likely to adhere. Physicians displayed more patient-centered communication and more favorably perceived patients who expressed positive affect, were more involved, and who were less contentious. Physicians were more contentious with black patients, whom they also perceived as less effective communicators and less satisfied. Finally, physicians who reported a patient-centered orientation to the doctor-patient relationship also were more patient-centered in their communication. The results suggest that reciprocity and mutual influence have a strong effect on these interactions in that more positive (or negative) communication from one participant leads to similar responses from the other. Physicians' encounters with black patients revealed communicative difficulties that may lower quality of care for these patients.

Assessment of decision-making capacity in older adults: an emerging area of practice and research

The convergence of the aging of our society, the increase in blended families, and an enormous intergenerational transfer of wealth has greatly expanded the incidence and importance of capacity assessment of older adults. In this article we discuss the emergence of capacity assessment as a distinct field of study. We review research efforts in two domains: medical decision-making capacity and financial capacity. Existing research in these two areas provides a first pass at many key questions related to capacity assessment, but additional studies that replicate, extend, and improve on this research are urgently needed. An agenda for future is detailed that recommends studies of a wide range of capacity constructs, focusing on clinical markers of diminished capacity, methods to improve clinical assessment, and the many intersections of law and clinical practice.

Predictors of good adherence of adolescents with diabetes (insulin-dependent diabetes mellitus)

OBJECTIVES

The purpose of this study was to identify the factors that predict good adherence to health regimens by adolescents with diabetes (insulin-dependent diabetes mellitus).

METHODS

Altogether, 300 individuals aged 13-17 years were randomly selected from the Finnish Social Insurance Institution's register. Ninety-seven per cent (N=289) of the selected adolescents returned the questionnaire. The data were analysed using the SPSS (Statistical Package for Social Sciences) for Windows software package. Logistic regression was used to find the factors that predict good adherence to health regimens.

RESULTS

About one-fifth (19%) of the respondents with diabetes felt that they complied fully with the health regimens, while 75% placed themselves in the category of satisfactory adherence, and the remaining 6% reported poor adherence. The most powerful predictor was the threat to mental wellbeing. The likelihood that adolescents who felt the disease to be a threat to their mental wellbeing would comply with health regimens was 7.68-fold as compared to those who did not regard the disease as a threat to their mental wellbeing. The next most powerful predictor was support from physician. The support from nurses, and the motivation, energy and willpower to take care of themselves and the threat to physical wellbeing, also predicted good adherence. The logistic regression model explained 82% of the variance, and the model predicted correctly 88% of the adolescents with good adherence.

DISCUSSION

This paper shows that adolescents with diabetes show quite good adherence. It also indicates the factors that predict good adherence to health regimens. To improve adherence, these factors should be given special attention in the care of adolescents.

An Evaluation of patients' preferences for osteoporosis medications and their attributes: The PREFER-international study

BACKGROUND

Patients' preferences for medications may be important in determining their compliance with therapy, particularly in the case of an asymptomatic chronic disease such as osteoporosis. Although preferences for certain attributes of osteoporosis medications, including dosing frequency and tolerability, can be evaluated in short-term clinical trials, years of use may be necessary for differences in effectiveness in reducing fracture risk to emerge.

OBJECTIVES

The primary aim of this study was to evaluate the relative importance of various attributes in determining patients' preferences for osteoporosis medications. Its secondary aim was to investigate patients' preferences for either of 2 hypothetical osteoporosis medications with different profiles.

METHODS

The Preference for Effective Regimens (PREFER)-International study was a cross-sectional survey of postmenopausal women with osteoporosis in France, Germany, Mexico, Spain, and the United Kingdom. Participants were recruited by their physicians in the 4 European countries and were identified by trained interviewers going door to door in Mexico. Participants were administered a questionnaire in which they were asked to rate and rank the importance of 7 medication attributes in determining their preferences for prescription osteoporosis medications. The attributes were side effects, out-of-pocket costs, effectiveness in improving bone health and preventing fractures, dosing frequency, formulation, administration procedure, and length of time on the market. They were also asked to indicate their preference for 2 hypothetical osteoporosis medications whose profiles differed in terms of efficacy (medication A reduced the risk of spine and hip fracture; medication B reduced spine fracture only), time on the market (10 years vs recently introduced), dosing frequency (weekly vs monthly), and dosing procedure (30- vs 60-minute wait after dosing).

RESULTS

Of 3000 patients interviewed, 1500 were receiving prescription treatment for osteoporosis. Across the rankings and ratings, effectiveness in reducing the risk of fracture emerged as the most important factor in determining patients' preferences for prescription osteoporosis medications, followed by side effects. Out-of-pocket costs, dosing frequency, formulation, time on the market, and dosing procedure were less important considerations among respondents from most countries. The majority (78%) of patients indicated a preference for medication A over medication B.

CONCLUSION

Effectiveness in reducing fracture risk was cited as the primary reason for patients' preference for prescription osteoporosis medications among postmenopausal women with osteoporosis from 4 European countries and Mexico.

Optimal matches of patient preferences for information, decision-making and interpersonal behavior: evidence, models and interventions

OBJECTIVE

A comprehensive review was conducted of the theoretical and empirical work that addresses the preference-match strategy in physician-patient communication.

METHODS

Searches were conducted on Medline, PsychINFO, InFoTrac One File Plus, Sociological Abstracts, and Dissertation Abstracts through 2004. The following keywords were used: patient preferred and received information; patient preferred and actualized treatment decision-making; patient-physician beliefs in shared decision-making; patient-physician match, fit, or concordance; reciprocal relationship or mutuality; doctor-patient affiliation, control, relationship; match/fit between patient and physician in affiliation, control, or relationship.

RESULTS

Findings revealed varying degrees of support for the positive effects of matching patients' preferred levels of information, decisional control, and consultative interpersonal behavior.

CONCLUSIONS

Findings justify not only continued but expanded research efforts in this area that would incorporate recommended changes in research design and implementation. PRACTICE AND RESEARCH IMPLICATIONS: Assessment strategies and match interventions are discussed that, if evidence continues to be supportive, might routinely optimize patient-physician encounters toward more positive outcomes. Methodological guidelines are suggested that can improve future preference-match studies of the patient-physician interaction. Practitioners need to consider adoption of patient-match assessment and intervention strategies in addition to recent exclusive concentrations on patient-centered and shared decision-making approaches.

Patient preference for once-monthly ibandronate versus once-weekly alendronate in a randomized, open-label, cross-over trial: the Boniva Alendronate Trial in Osteoporosis (BALTO)

OBJECTIVE

Ibandronate, a potent nitrogen-containing bisphosphonate, can be administered with extended interval dosing. Patient preferences were assessed for once-monthly versus once-weekly bisphosphonate treatment using a previously developed, open-label, cross-over trial design.

RESEARCH DESIGN AND METHODS

This was a 6-month, prospective, randomized, open-label, multi-center study with a two-period and two-sequence cross-over treatment design. After screening, eligible patients (postmenopausal women with osteoporosis) were randomized to once-monthly ibandronate 150 mg followed by once-weekly alendronate 70 mg for a total of 6 months (Sequence A) or once-weekly alendronate followed by once-monthly ibandronate for a total of 6 months (Sequence B). The primary objective was to evaluate patient-reported preference for either the once-monthly ibandronate regimen or the once-weekly alendronate regimen based on responses to a preference questionnaire.

RESULTS

A total of 342 patients were enrolled into this study (Sequence A, 170; Sequence B, 172). In the primary analysis of patient preference, 71.4% of women selected once-monthly ibandronate and 28.6% of women selected once-weekly alendronate. Overall, 66.1% preferred the once-monthly ibandronate regimen to the once-weekly alendronate regimen (26.5%) and 7.4% of participants stated no preference for either regimen. The preference rate for once-monthly ibandronate was statistically significant (p < 0.0001). 'Ease of following a treatment regimen for a long time' was the most common reason given for patient preference for both the once-monthly ibandronate (61%, 169/276) and once-weekly alendronate (25%, 70/276) regimens. Additionally, 17% (47/276) of patients who preferred once-monthly ibandronate chose 'it is easier to tolerate side effects' as did 4.3% (12/276) of patients who preferred alendronate. Significantly more women found once-monthly ibandronate to be more convenient (p < 0.0001).

CONCLUSIONS

Significantly more women with postmenopausal osteoporosis preferred once-monthly ibandronate therapy to once-weekly alendronate therapy, and found the once-monthly regimen to be more convenient. Ease of following a treatment regimen for a long time was the most common reason given for the patients' preferences.
