Clinical and Economic Implications of Hydroxyurea Intolerance in Polycythemia Vera in Routine Clinical Practice.

Background/Objectives: Polycythemia vera (PV) is a chronic hematologic neoplasm commonly treated with hydroxyurea (HU). We utilized the advanced digitalized database of Maccabi Healthcare Services to retrospectively investigate the clinical and economic implications of HU intolerance in the routine clinical care of PV patients in Israel. Methods: We collected data on demographics, physician visits, hospitalizations, laboratory results, medication purchases, cardiovascular and thrombotic events, mental health, economic outcomes, and mortality. Outcomes included cardiovascular and other thrombotic events, disease progression, mental health events, economic outcomes, and overall mortality. Results: Of the 830 patients studied, 3 (0.4%) were resistant to HU treatment, 318 (38.3%) were intolerant to HU treatment, and 509 (61.3%) were stable on HU treatment. The venous thrombosis rate was significantly higher among HU-intolerant compared to HU-stable patients (1.58 vs. 0.47 per 100 person-years [PY], respectively; p < 0.001). The rate of progression to myelofibrosis was 6 vs. 0.9 per 100 PY in HU-intolerant patients vs. HU-stable patients, respectively (p < 0.001), and the rate of progression to acute myeloid leukemia (AML) was 1.16 vs. 0.2 per 100 PY in HU-intolerant patients vs. HU-stable patients, respectively (p < 0.001). The phlebotomy requirement, mortality rate, and total hospitalization days among HU-intolerant patients were significantly higher than in HU-stable patients (p = 0.049, p < 0.001, p < 0.001, respectively). More mental health-related events were noted in HU-intolerant patients vs. HU-stable patients (p = 0.007), and the total healthcare cost ratio was 2.65 for the HU-intolerant patients compared with HU-stable patients. Conclusions: This study suggests that HU-intolerant patients are more likely to have worse outcomes than HU-stable patients, highlighting the need for the close monitoring of these patients for disease-related complications or progression.

Association Between Physical Activity and Use of Complementary Medicine by Female Oncology Patients in an Integrative Palliative Care Setting.

Objective: To examine the association between physical activity and the reported use of complementary medicine by patients with breast and gynecological cancer referred or self-referred to a complementary/integrative medicine (CIM) consultation within a palliative care context. Methods: Retrospective observational study analyzing the medical files of patients referred to a CIM consultation provided within a specialized integrative oncology clinic for demographic and cancer-related parameters; participation in physical exercise and activities; and current use of nonconventional medical practices. Quality of life (QoL) outcomes were assessed during the initial CIM consultation by using the Edmonton Symptom Assessment Scale (ESAS) tool. Results: Among the 162 patient files examined, participation in physical activities was reported in 152, of whom 83 were identified as active and 69 inactive according to the American Cancer Society guidelines. A logistic multivariate regression model showed that physical activity was associated with higher rates of herbal/dietary supplement use for noncancer-related outcomes (odds ratio = 7.21, 95% confidence interval [CI] 1.6-32.46, p = 0.01); more frequently reported use of acupuncture for cancer-related outcomes (odds ratio = 7.79, 95% CI 1.93-31.5, p = 0.004); and lower ESAS scores for well-being (odds ratio = 0.77, 95% CI 1.0.65-0.92, p = 0.004), indicating better QoL. Conclusion: Physical activity was found to be associated with a greater use of CIM (specifically herbal/dietary supplement use and acupuncture) in patients with breast and gynecological cancer during oncology treatment. Further research is needed to explore whether CIM use and physical activity are influenced by patients' health-belief models of care, and whether the CIM consultation can promote physical activity among these patients.

Barriers and challenges in integration of anthroposophic medicine in supportive breast cancer care.

In the last decade, more and more oncology centers are challenged with complementary medicine (CM) integration within supportive breast cancer care. Quality of life (QOL) improvement and attenuation of oncology treatment side effects are the core objectives of integrative CM programs in cancer care. Yet, limited research is available on the use of specific CM modalities in an integrative setting and on cancer patients' compliance with CM consultation. Studies are especially warranted to view the clinical application of researched CM modalities, such as anthroposophic medicine (AM), a unique CM modality oriented to cancer supportive care. Our objective was to characterize consultation patterns provided by physicians trained in CM following oncology health-care practitioners' referral of patients receiving chemotherapy. We aimed to identify characteristics of patients who consulted with AM and to explore patients' compliance to AM treatment. Of the 341 patients consulted with integrative physicians, 138 were diagnosed with breast cancer. Following integrative physician consultation, 56 patients were advised about AM treatment and 285 about other CM modalities. Logistic multivariate regression model found that, compared with patients receiving non-anthroposophic CM, the AM group had significantly greater rates of previous CM use [EXP(B) = 3.25, 95% C.I. 1.64-6.29, p = 0.001] and higher rates of cancer recurrence at baseline (p = 0.038). Most AM users (71.4%) used a single AM modality, such as mistletoe (viscum album) injections, oral AM supplements, or music therapy. Compliance with AM modalities following physician recommendation ranged from 44% to 71% of patients. We conclude that AM treatment provided within the integrative oncology setting is feasible based on compliance assessment. Other studies are warranted to explore the effectiveness of AM in improving patients' QOL during chemotherapy.

Touching ethics: assessing the applicability of ethical rules for safe touch in CAM--outcomes of a CAM (complementary and alternative medicine) practitioner survey in Israel.

INTRODUCTION: Recently, ethical guidelines regarding safe touch in CAM were developed in Israel. Publishing ethical codes does not imply that they will actually help practitioners to meet ethical care standards. The effectiveness of ethical rules depends on familiarity with the code and its content. In addition, critical self-examination of the code by individual members of the profession is required to reflect on the moral commitments encompassed in the code. METHODS: For the purpose of dynamic self-appraisal, we devised a survey to assess how CAM practitioners view the suggested ethical guidelines for safe touch. We surveyed 781 CAM practitioners regarding their perspectives on the safe-touch code. RESULTS: There was a high level of agreement with general statements regarding ethics pertaining to safe touch with a mean rate of agreement of 4.61 out of a maximum of 5. Practitioners concurred substantially with practice guidelines for appropriate touch with a mean rate of agreement of 4.16 out of a maximum of 5. Attitudes toward the necessity to touch intimate areas for treatment purposes varied with 78.6% of respondents strongly disagreeing with any notion of need to touch intimate areas during treatment. 7.9% neither disagreed nor agreed, 7.9% slightly agreed, and 7.6% strongly agreed with the need for touching intimate areas during treatment. There was a direct correlation between disagreement with touching intimate areas for therapeutic purposes and agreement with general statements regarding ethics of safe touch (Spearman r=0.177, p<0.0001), and practice guidelines for appropriate touch (r=0.092, p=0.012). CONCLUSION: A substantial number of practitioners agreed with the code, although some findings regarding the need to touch intimate area during treatments were disturbing. Our findings can serve as a basis for ethical code development and implementation, as well as for educating CAM practitioners on the ethics of touch.

Integrative pediatric care: parents' attitudes toward communication of physicians and CAM practitioners.

OBJECTIVE: In this study, we explored parents' perspectives toward complementary and alternative medicine (CAM) use by their children and its impact on parent-doctor and doctor-CAM-practitioner communication. PATIENTS AND METHODS: We designed a 2-arm study of parents who approached either conventional primary care or CAM clinics with their children to consult physicians or practitioners regarding their child's health. RESULTS: A total of 599 parents responded to our questionnaire (319 in 5 conventional clinics [83.9% response rate] and 280 in 21 CAM clinics [71.2% response rate]). Parents in conventional clinics reported less use of CAM by their children within the previous year (35.3% vs 73.7%; P < .0001) but used more traditional and homemade remedies (46.4% vs 12.7%; P < .0001). Both parent groups largely supported informing their child's physician regarding CAM use and expected the physician to initiate a CAM-related conversation and to refer their child to a CAM practitioner. The 2 groups' respondents largely supported communication between the child's physician and the CAM practitioner by the use of a referral/medical letter. Compared with respondents in CAM clinics, parents in conventional clinics were more supportive of CAM integration in a pediatric primary care setting and envisioned a more dominant role of physicians regarding CAM referral and a significant role of physicians in providing CAM. CONCLUSIONS: Parents who are referred to conventional and CAM clinics express distinctive attitudes toward CAM integration in pediatric care. Parents perceive physician-CAM practitioner communication as highly important and instrumental in promoting their children's health and safety.

Bridging the physician and CAM practitioner communication gap: suggested framework for communication between physicians and CAM practitioners based on a cross professional survey from Israel.

OBJECTIVE: Our study aimed to develop a framework to improve communication between physicians and CAM practitioners regarding mutual patients. METHODS: Following a modified Delphi process, we developed preliminary recommendations regarding communication between physicians and CAM practitioners. We then surveyed 473 physicians and 781 CAM practitioners regarding their opinions on these recommendations. RESULTS: High reliability and validity of the survey were found among the physicians and CAM practitioners (Cronbach's alpha score of .94 and .83, respectively). Physicians and CAM practitioners considered communication regarding mutual patients important (80% and 97%, respectively; P<.001). A medical/referral letter was the preferred communication mode. Physicians and CAM practitioners concurred on four elements that should be included in such a referral letter: conventional-CAM diagnosis with coherent terminology, possible conventional-CAM treatment interactions, description of the treatment plan and its goals, and quality issues regarding CAM supplements. CONCLUSIONS: A practical framework for advancing physician-CAM practitioner communication is feasible, and may be applied in daily medical care with the goal of bridging the patient-physician-CAM practitioner communication gap. PRACTICE IMPLICATIONS: Communication between physicians and CAM practitioners regarding mutual patients is important. Establishing a framework for the mode and content of such communication is feasible.

Development of ethical rules for boundaries of touch in complementary medicine--outcomes of a Delphi process.

The practice of complementary medicine (CAM) often involves touch. The unique philosophy of many CAM therapies, and the setting in which treatments are provided create a therapeutic space which may be less clearly defined than in conventional settings - a space in which the boundaries between professional touch and personal/intimate touch may become easily obscured. Thus, complementary therapists need clear definitions and firm boundaries in order to maintain therapeutic efficacy and commitment. The aim of the process described in this article, was to develop ethical guidelines for boundaries of touch that will promote the safety and protection of the public which use CAM. Through a modified Delphi process, a diverse group of CAM practitioners, physicians, ethicists, legal consultants, health policy specialists, and representatives from the public, developed Ethical Rules for Boundaries of Touch in CAM. These guidelines may be implemented in ethical codes of professional CAM organizations, and also serve as a foundation for curriculums in ethics in CAM schools.
