Preferences for pharmacist counselling in patients with breast cancer: a discrete choice experiment.

With the shift of a large proportion of cancer chemotherapy recipients to ambulatory care, the role of hospital pharmacists has changed, and their provision of information is essential care for cancer patients. There is little research on pharmacist-patient relations, particularly about pharmacist counselling, in Japan. To meet patients' needs, pharmacist counselling should be optimized. Here, breast cancer patients' preferences for pharmacist counselling were assessed using a discrete choice experiment. Bayesian nonlinear optimal methodology was employed to obtain six attributes (attitude of pharmacist, quality of information, explanation of side effects, frequency of pharmacist counselling before starting chemotherapy, cost of pharmacist counselling, and follow-up with the pharmacist after starting chemotherapy) of two to three levels each. The attributes and levels were used to create 12 hypothetical scenarios that were divided into two questionnaires of six choice sets each. Two hundred eighty participants were randomly assigned to complete one of these questionnaires (blocks). Attributes were analyzed by conditional logit model to determine significant predictors of patient preferences. The responses of 278 patients to 1667 scenarios were analyzed. Attitude of pharmacist, quality of information, cost of pharmacist counselling, and follow-up with the pharmacist after starting chemotherapy were significant predictors of patient preferences, with quality of information receiving the highest priority. Thus patients receiving pharmacist counselling before starting chemotherapy prefer to interact with a pharmacist with a friendly, interested attitude who provides individualized information. Further research is needed to elucidate the information that Japanese patients consider most important and to enhance pharmacist-patient communication.

Development and validation of the Japanese version of the Decisional Conflict Scale to investigate the value of pharmacists' information: a before and after study.

BACKGROUND: The information provided in patient-centered care and shared decision-making influences patients' concerns and adherence to treatment. In the decision-making process, patients experience decisional conflict. The Decisional Conflict Scale (DCS) is a 16-item, self-administered questionnaire consisting of 5 subscales developed to assess patients' decisional conflict. This study aimed to develop the Japanese version of the DCS and to clarify the influence of the information provided by pharmacists' on decisional conflict among patients with cancer. METHODS: We developed the Japanese version of the DCS by using the forward-backward translation method. One hundred patients who were recommended a new chemotherapy regimen were recruited. The psychometric properties of the Japanese DCS, including internal consistency, convergent validity, discriminant validity, and construct validity, were examined. We assessed the decisional conflict of patients before and after the pharmacists' provision of information. RESULTS: Ninety-four patients, predominately female, with an average age of 58.1 years were sampled. The scores on the 5 subscales of the DCS showed high internal consistency (Cronbach's alpha = 0.84-0.96). Multi-trait scaling analysis and cluster analysis showed strong validity. The mean total DCS score decreased significantly from 40.2 to 31.7 after patients received information from the pharmacists (p < 0.001, paired t-test). Scores on all 5 subscales, namely, uncertainty, informed, values clarity, support, and effective decision, also significantly improved (p < 0.001 for all categories, paired t-test). CONCLUSIONS: The psychometric properties of the Japanese version of the DCS are considered appropriate for it to be administered to patients with cancer. Pharmacists' provision of information was able to decrease decisional conflict among patients with cancer who were recommended a new chemotherapy regimen.

Low-dose glucocorticoid therapy complements the pituitary-adrenocortical system and reduces anxiety and insomnia in myasthenia gravis patients.

Myasthenia gravis (MG) is an autoimmune disorder generally mediated by antibodies against the acetylcholine receptors of the skeletal muscles. Depending on the disease burden, MG patients may experience chronic dysregulation of both the hormonal stress axis and the immune system, consequently, aggravating the disease itself but also leading to secondary psychopathological abnormalities. A long-term clinical course requires long-term glucocorticoid (GC) therapy, which may change the psychological state by affecting the pituitary-adrenocortical system in MG patients. In this study, we investigated the function of the pituitary-adrenocortical system in MG patients who were treated with prednisolone (PSL) and evaluated their quality of life by using the Medical Outcomes Study 36-item Short-Form Health Survey and the 28-item general health questionnaire (GHQ-28). ACTH and cortisol levels in the plasma of patients who were treated with PSL (PSL[+] group, n = 18) were lower than those in the plasma of patients who were treated without PSL (PSL[-] group, n = 29; P < 0.05 and P < 0.01, respectively). In the PSL(+) group, we confirmed that cortisol levels negatively correlated with daily PSL dosages (P < 0.05). The anxiety and depression scores from the GHQ-28 in the PSL(+) group were lower than those in the PSL(-) group (P < 0.05, respectively). There was no significant correlation between cortisol levels and corticotropin levels in plasma of the PSL(-) group. However, we confirmed that corticotropin levels positively correlated with cortisol levels in plasma (P < 0.01) and negatively correlated with anxiety/insomnia scores from the GHQ-28 (P < 0.05) in the PSL(+) group. In conclusion, low-dose GC treatment complemented the pituitary-adrenocortical system and improved the psychological state in MG patients.

[Direct conversion from low-dose morphine to transdermal fentanyl: efficacy for cancer pain and quality of life].

The efficacy and QOL in a cancer pain patient who converted to transdermal fentanyl from low-dose morphine (n=5) or high-dose morphine (n=5) were retrospectively compared. Cancer pain control was evaluated by visual analogue scales (VAS) score. Patients switched from low-dose morphine demonstrated significantly better scales. The number of morphine rescues was also significantly less in the low-dose conversion group. In conclusion, conversion from low-dose morphine is useful for cancer pain control from the aspect of efficacy and QOL.

Immunosuppressant pharmacodynamics on peripheral-blood mononuclear cells from patients with ulcerative colitis.

We investigated peripheral-blood mononuclear cell (PBMC) response to immunosuppressive drugs and its influence on glucocorticoid therapy in ulcerative colitis (UC). IC50s of immunosuppressive drugs on in vitro blastogenesis of PBMCs stimulated with concanavalin A were estimated in 76 UC and 146 healthy subjects. Individual differences in IC50s for prednisolone, methylprednisolone, cyclosporine, and tacrolimus on blastogenesis of PBMCs from UC patients were spread from 11.0 to 1000, 0.6 to 1000, 0.01 to 1000, and 0.001 to 4.6 ng/ml, respectively. Normal upper thresholds for IC50s of these drugs were estimated from the mean + 2 S.D. of the IC50s of healthy PBMCs, and the patients exhibiting IC50s over these levels were arbitrarily considered as resistant. The incidences of resistance to glucocorticoids and cyclosporine in UC were significantly higher than those in healthy subjects (p < 0.0005). In 14 UC patients, there was a significant correlation between amounts of prednisolone (p < 0.05) or period of prednisolone administration (p < 0.05) for UC treatment and prednisolone IC50. The results showed that large individual deviations in PBMC response to the drugs were observed in UC, and UC patients exhibiting low PBMC sensitivity to prednisolone required a high prednisolone amount as well as long period of prednisolone administration for treatment. Thus, the drug sensitivity tests could be informative to single out refractory patients to the immunosuppressive therapy.
