Drug price,dosage and safety: Real-world evidence of oral hypoglycemic agents

ObjectivesDrug price reduction is one of the major policies to restrain pharmaceutical expenses worldwide. This study explores whether there is a relationship between drug price and clinical quality using real-world data.MethodsPatients with newly-diagnosed type 2 diabetes receiving metformin or sulfonylureas during 2001 and 2010 were identified using the claim database of the Taiwan universal health insurance system. Propensity score matching was performed to obtain comparable subjects for analysis. Pharmaceutical products were categorized as brand-name agents (BD), highpriced generics (HP) or low-priced generics (LP). Indicators of clinical quality were defined as the dosage of cumulative oral hypoglycemic agents (OHA), exposure to other pharmacological classes of OHA, hospitalization or urgent visit for hypoglycemia or hyperglycemia, insulin utilization and diagnosis of diabetic complications within 1 year after diagnosis.ResultsA total of 40,152 study subjects were identified. A generalized linear mix model showed that HP and BD users received similar OHA dosages with comparable clinical outcomes. By contrast, LP users had similar outcomes to BD users but received a 39% greater OHA dosage. A marginally higher risk of poor glycemic control in LP users was also observed.ConclusionsDrug price is related to indicators of clinical quality. Clinicians and health authorities should monitor the utilization, effectiveness and clinical safety indicators of generic drugs, especially those with remarkably low prices.     

A community pharmacist home visit project for high utilizers under a universal health system: A preliminary assessment

Due to the increasing prevalence of multimorbidity, the percentage of heavy users of health care services increased rapidly. To contain inappropriate outpatient visits and improve better medication management of high utilizers, the National Health Insurance Administration in Taiwan launched a community pharmacist home visit (CPHV) project for high utilizers in 2010. We employed a natural experimental design to evaluate the preliminary effects of the CPHV project. The intervention group consisted of patients enrolled in the CPHV project during 2010 and 2013. Patients in the comparison group were non-enrollees selected via a propensity score matching technique. A difference-in-differences analysis was conducted by using multilevel models to examine the effects of the project. The average number of physician visits decreased from 130.0 to 98.9 visits (23.8%) among the CPHV project enrollees, while the average number decreased from 99.5 to 89.5 visits (10.1%) among the non-enrollees, with a net effect of a 21.0-visit reduction. The CPHV project also led to modest reductions in the number of medication items used per day, the probability of hospital admission and yearly healthcare expenses. The CPHV project seems promising for decreasing health care utilization and costs of the patients with high-needs.     

Comparison of Two Devices for Intraoperative Portal Venous Flow Measurement in Living-Donor Liver Transplantation: Transit Time Ultrasound and Conventional Doppler Ultrasound

Background

Intraoperative portal venous flow measurement provides surgeons with instant guidance for portal flow modulation during living-donor liver transplantation (LDLT). In this study, we compared the agreement of portal flow measurement obtained by 2 devices: transit time ultrasound (TTU) and conventional Doppler ultrasound (CDU).

Effective Decision-Making and Decisional Regret in Living Kidney Donors of Taiwan

Background

While most living kidney donors are satisfied with their decision and do not regret donating, few studies have been conducted on the determinants related to the effectiveness and regret of the decision. This study aims to explore the relationship between basic attributes, quality of life, positive affect, negative affect, effectiveness of decision-making, and regret in living kidney donors.

Anesthesia Management and Fluid Therapy in Right and Left Lobe Living Donor Hepatectomy

Objective

Right lobe living donor hepatectomy poses a greater risk for the donor in relation to blood loss. The aims of this study were to compare anesthetic and intraoperative fluid management in right and left lateral segment living donor hepatectomy.

The Correlation Between CVP and SVV and Intraoperative Minimal Blood Loss in Living Donor Hepatectomy

Background

Blood loss during liver surgery is found to be correlated with central venous pressure (CVP). The aim of the current retrospective study is to find out the cutoff value of CVP and stroke volume variation (SVV), which may increase the risk of having intraoperative blood loss of more than 100 mL during living liver donor hepatectomies.

The Risk Factors of mTORi-Associated Posttransplant Proteinuria

Treatment with mammalian target of rapamycin inhibitors (mTORi) has been associated with an increased incidence of proteinuria after kidney transplantation as compared to other immunosuppressive agents. Proteinuria after mTORi use may occur in different clinical conditions and the precise mechanism remains unclear. The objective of this study was to investigate the related risk factors for proteinuria after mTORi treatment in kidney transplant recipients. This retrospective observational study population consisted of kidney transplant recipients followed up in a medical center in Southern Taiwan from January 1999 to April 2016. The baseline characteristics and transplantation-related profiles were collected at the time of enrollment. We examined risk factors for mTORi-associated proteinuria using a multivariate logistic regression analysis. P < .05 was considered as statistically significant. Hyperlipidemia and obesity at the initiation of mTORi treatment were strong predictors for proteinuria. Earlier identification of these risk factors may assist physicians in deciding the best candidate for mTORi conversion in order to optimize transplantation outcomes.     

Timely thrombectomy can improve patency of hemodialysis arteriovenous fistulas

Objective

The urgency with which salvage of thrombosed vascular accesses for dialysis should be attempted remains unknown. We examined the effect of a timely thrombectomy approach on vascular access outcomes for dialysis.

Effects of Acupressure on Sleep Quality and Psychological Distress in Nursing Home Residents: A Randomized Controlled Trial

ObjectiveTo compare the efficacy of acupressure with sham acupressure in older-adult nursing home residents presenting with poor sleep quality and psychological distress.DesignProspective, randomized, double-blind, sham-controlled trial.Setting and participantsSixty-two nursing home residents with poor sleep quality and psychological distress participated in this study. Participants were randomly assigned to an experimental group (n = 31) receiving acupressure at true acupoints (Baihui, Juque, Neiguan, Tianzhu, and Yongchung) or control group (n = 31) receiving acupressure at sham points. All participants received 20 minutes of acupressure before sleeping 3 times a week for 8 weeks. All participants were blinded to group allocation.MeasuresSleep quality and psychological distress were measured using the Pittsburgh Sleep Quality Index and the Kessler Psychological Distress scale, respectively. Both groups' outcomes were assessed by assessors blinded to group allocation at the baseline, the end of the intervention, and 1 month after the intervention.ResultsThe experimental group demonstrated significantly more improvement in sleep quality than did the control group at the end of the intervention (10.5 vs 13.3) and 1 month after the intervention (8.3 vs 14.2; both P ≤ .001). Moreover, the experimental group had lower psychological distress levels than did the control group at 1 month after the intervention (14.6 vs 17.9, P = .05). Furthermore, significant differences in mean sleep quality (F = 60.8, P < .001) and psychological distress (F = 24.6, P < .001) were observed in the experimental group between the measurements at baseline and after the intervention.ConclusionsAcupressure at true acupoints improves sleep quality, reduces psychological distress, and provides more clinically beneficial effects compared with that at sham points. Future studies should examine whether these effects are maintained in the long term.
