A comparison of diabetes medication adherence and healthcare costs in patients using mail order pharmacy and retail pharmacy

Patient satisfaction and behavioural intention in using the home medication delivery service in an ambulatory oncology centre

BACKGROUND

The COVID-19 pandemic has increased usage of medication delivery service (MDS) significantly. MDS improves adherence to medication and clinical outcomes.

OBJECTIVES

To study behavioral change factors that affect adoption of MDS, determine existing patient satisfaction level, and make recommendations to improve MDS adoption.

METHODS

A single-institution, cross-sectional survey was conducted at the outpatient pharmacy of the largest ambulatory cancer centre in Singapore. The survey consisted of sections on demographics, Theory of Planned Behavior constructs and patient satisfaction questions. Descriptive analysis and logistic regression were used.

RESULTS

A total of 881 patients responded. Respondents were mostly Chinese, female and subsidized patients, with a mean age of 62.4 years old. MDS use is strongly predicted by favourable attitude (OR 3.54, 95%CI 2.64-4.75; p < 0.001) and subjective norm (OR 3.07, 95%CI 2.30-4.09; p < 0.001) towards its use and greater perceived behavioral control (OR 2.48; 95%CI 1.86-3.30; p < 0.001). Being ill or frail has been identified as facilitators, while absence of face-to-face consultation and cost of delivery were barriers to the adoption of MDS. Encouragingly, the satisfaction level of our existing patients was generally high (80.2, SD16.7). Recommendation to improve MDS adoption targets facilitators and barriers identified and aims to further elevate patient satisfaction level. Establishment of a centralised pharmacy for MDS together with a call centre would be essential in the long run.

CONCLUSIONS

MDS is becoming increasingly important, in line with our national strategy. Implementation of suggested short-term and long-term measures will encourage its use.

Associations between pharmacy choice and influenza vaccination: Mail order vs community pharmacy users

BACKGROUND: Despite the effectiveness of vaccines, US adult vaccination rates remain low. This is especially true for the influenza vaccine, which is recommended annually and widely available. The accessibility of community pharmacies as convenient places to receive influenza vaccines has been shown to increase uptake. However, use of mail order pharmacies may reduce in-person pharmacist encounters and reduce the likelihood that users receive annual influenza vaccines. OBJECTIVE: To determine the association between the type of pharmacy a patient uses and their likelihood of receiving an influenza vaccine. METHODS: This cross-sectional cohort study used the 2018 Medical Expenditure Panel Survey to observe noninstitutionalized US adult pharmacy users. Pharmacy type was dichotomized into community use only vs any mail order pharmacy use. Multivariable weighted logistic regression was used to identify associations between the type of pharmacy used and influenza vaccination, adjusting for sociodemographic, health status, and health care access and utilization confounders. All analyses were stratified by age (< 65 and ≥ 65 years). RESULTS: The aged younger than 65 years and aged 65 years and older samples had 8,074 and 4,037 respondents who represented 95,930,349 and 40,163,276 weighted observations, respectively. Compared with community pharmacy users, mail order users were more likely to be aged 65 and older, be White, have high income, and have a usual source of care (P < 0.0001). Adjusted odds ratios (AORs) for influenza vaccination were significantly lower among community pharmacy users than mail order users among individuals aged younger than 65 years (AOR=0.71; 95% CI = 0.580.87) but was not significant among those aged 65 years and older (AOR = 0.87; 95% CI = 0.69-1.09). CONCLUSIONS: Community pharmacy users aged younger than 65 years are less likely to receive the influenza vaccine than their mail order pharmacy user counterparts. These counterintuitive results could be caused by residual confounding due to differences in factors that influence pharmacy use type and vaccination likelihood. Further exploration is needed to account for differences between these populations that independently drive vaccination choice.

Home Drug Delivery Service from the Perspective of Community Pharmacy Staff in Saudi Arabia

Background: In response to COVID-19, many big pharmacy chains in Saudi Arabia have started to provide home drug delivery services. This study aims to understand home drug delivery service from the perspective of community pharmacists in Saudi Arabia. Also, the study investigates the obstacles that may limit the use of home drug delivery service. Methods: A cross-sectional self-reported survey was distributed from February 2021 to May 2021. Descriptive analysis of sociodemographic characteristics was conducted and presented. Frequencies and percentages were calculated for all variables. Results: A total of 965 community pharmacists were surveyed. Most of the pharmacists, (73.5%) were young, aged 23 to 34 years old. The vast majority of the participants, (93.6%), said that the service will improve drug adherence. The lack of required knowledge and skills among pharmacists could be the main obstacle to implement home drug delivery service (34%). A shortage in the number of community pharmacists was the second main obstacle (24%). Conclusion: Home delivery services in the future may largely replace the tradition of going in person to the pharmacy. There are obstacles that may limit the full use of the service like shortage in number of pharmacists and the lack of required training.

Evaluation of pharmacy value-added services in public health facilities: Staff perception and cost analysis

Background

Pharmacy Value Added Services (VAS) were introduced in Malaysian public health facilities to facilitate the process of medicine collection. Examples include Drive-through pharmacy, Medicine by Post, SMS Take&Go, Appointment Card and medicine locker, commonly referred to as Medibox.

Objectives

To assess the perception of VAS among pharmacy staff, and to compare the time and cost needed to prepare medications for VAS and conventional counter service.

Methods

A cross-sectional study was conducted in 17 public health facilities across Kuala Lumpur and Putrajaya from May until September 2020. There were two parts of this study: 1) a survey on the perception of VAS among pharmacy staff, which assessed respondents' experience of handling VAS and their perception towards the services; and 2) a cost analysis to compare the direct cost of preparing refill medications for VAS and conventional counter service, estimated from average salary and direct non-medical cost.

Results

290 respondents answered the survey. Most respondents had a positive opinion about VAS. Lack of storage and insufficient manpower were the top two barriers in VAS utilisation and implementation as perceived by pharmacy staff. The average time (in minutes) needed to prepare one prescription was highest for Medicine by Post service (10.31), followed by Medibox (10.25), Appointment Systems (6.24) and conventional counter service (3.99). Medibox had the highest average cost per prescription (RM5.49), followed by Medicine by Post (RM5.05), Appointment Systems (RM2.89) and conventional counter service (RM1.75).

Conclusions

The majority of the respondents involved in this study acknowledged the benefits of VAS to patients, but there were aspects of the services that could be improved. Preparation of patient medication for VAS requires significantly more time and cost than conventional counter service, indicating the need to review and streamline implementation of the services.

•

VAS offer various benefits to patients, but they come with additional cost.

•

The highest cost for VAS implementation was observed with Medibox, followed by Medicine by Post and Appointment Systems.

•

There is a need to streamline the procedure and provide sufficient workforce to cater for the increasing demand for VAS.

Public Perceptions About Home Delivery of Medication Service and Factors Associated with the Utilization of This Service

INTRODUCTION

Home medication delivery service is a major service for the public. It reduces overcrowding and unnecessary visits to health centers. This study aims to investigate the public perception of home delivery of medication service in Jordan and evaluate factors affecting the use of this service.

METHODS

The study was conducted in March 2022 using an online survey. Participants were asked to fill out a validated questionnaire to evaluate their perception of home delivery of medication service.

RESULTS

Among the 1032 adult participated in this study, the majority reported that they had heard of home delivery of medication service (n = 832, 80.6%). However, only 30.9% of them have used this service before. Results showed that 71.4% of the participants (n = 737) believe that home delivery of medication service is more convenient and accessible than in-store drug refill. In addition, 65.6% of the participants (n = 677) believed that home delivery of medication service is suitable only for refill-prescription drugs (65.0%). The main pros of the service as perceived by the study participants were to serve sick patients, elderly, and disabled people (n = 822, 79.7%). In contrast, the inability of patients to build a professional relationship with pharmacists using home delivery of medications service was the most perceived con of this service (n = 627, 60.8%). Finally, regression analysis revealed that older participants, those with chronic diseases, and those who visit community pharmacies two times or more per month revealed higher use of the service (P = <0.05).

CONCLUSION

This study has shown that most participants showed positive perceptions toward the home delivery of medication services. However, participants believed that this service may decrease pharmacist's patient contact time, thus affecting the quality of medication counseling. More comprehensive future studies are necessary to examine the financial aspects of such a service and its associated drawbacks.

Impacts of a Mail-Order Service for Refilling Prescriptions on Patient Satisfaction and Operational Load at a Comprehensive Cancer Center in Jordan

Background

Mail-order services for refilling prescriptions for medications have been established in many countries and have increased patient satisfaction. We developed a mail-order service for the outpatient pharmacy of a comprehensive cancer center in Jordan.

Objective

To describe the implementation of a mail-order service and to report the impact of the service on patient satisfaction and the pharmacy workload.

Methods

A multidisciplinary team was formed to plan a mail-order service for refilling prescriptions for medications, and a survey was designed to evaluate patient satisfaction with the service. Patients were instructed to call the refill call center and order their medications at least 48 hours before their refill is due. The pharmacy workflow for refilling prescriptions was evaluated, and the time required with and without the mail-order service was documented, with a calculation of the time saved.

Results

At 1 year after the mail-order service had been established, 14 200 prescriptions had been refilled through the service, with the majority (97.5%) dispensed within 48 hours of the order time. As per the survey conducted with 219 patients, on the overall satisfaction, 69.4% reported being highly satisfied with the service and 27.9% reported being satisfied. The problems reported with the service were delay in arrival (n = 23, 10.5%), medication-related errors (n = 9, 4.1%), cash-related error (n = 1, 0.45%), improper storage condition (n = 1, 0.45%), and delivery to the wrong address (n = 4, 1.8%). The service was also associated with reduced overall time for processing in the outpatient pharmacy service; for patients receiving their medications from the pharmacy, resulting in reduced patients' overall waiting time (from 11.4 to 8.2 minutes). The service resulted in saving of 0.4 full-time employee at 1 year of implementation.

Conclusions

A mail-order service for refilling prescriptions within a hospital setting had positive outcomes on both patient satisfaction and the pharmacy workflow. The major issues were related to transportation and logistics.

Satisfaction among patients and caregivers receiving value-added services during the COVID-19 pandemic outbreak in a tertiary hospital in the Perak state of Malaysia

Objectives

Patient satisfaction was used as an indicator of service quality in the public hospitals. The pharmacy value-added services (VAS) were intensified after the COVID-19 outbreak, and evaluation of user’s satisfaction was important for service improvement.

Methods

This was a single-centre, cross-sectional, web-based study in the outpatient pharmacy in a tertiary hospital in the Perak state of Malaysia. Patients and caregivers aged 18 years and above, received at least one prescription refill using the pharmacy VAS from April to September 2020, were included. The questionnaire was adapted from a validated tool, underwent face and content validation before dissemination. The link was disseminated to the targeted population through short messages service (SMS).

Key findings

Out of 1200 invited people, 303 agreed to participate. Majority of the respondents were male (160, 52.8%), Chinese (156, 51.5%), with tertiary education (201, 66.3%) and retiree (112, 37.0%). Out of a maximum score of 5, the overall mean satisfaction score was 4.42 (SD: 0.55). The respondents were most agreeable to time-saving benefits of the pharmacy VAS (4.56 ± 0.63). Majority of the respondents felt that pharmacy VAS had made their life easier (290, 95.7%) and planned to recommend the pharmacy VAS to others (292, 96.4%) Respondents aged more than 60 (versus age 18–35, β = 2.375, P &lt; 0.001) and those who used drive-through service (versus SPUB, β = 2.272, P = 0.001) reported higher satisfaction scores. Several suggestions were made for service improvement, including longer operating hours (18, 6.0%), upgraded communication system (9, 3.0%), smoother registration process (9, 3.0%), more polite staff (9, 3.0%), selection of preferred postage delivery time (6, 2.0%) and promotion of VAS (4, 1.3%)

Conclusions

Majority of the respondents were highly satisfied towards the pharmacy VAS. Future studies should compare the satisfaction of VAS with traditional counter service to compare the level and factors that contributed to the users’ satisfaction.

Trends in Mail-Order Pharmacy Use in the U.S. From 1996 to 2018: An Analysis of the Medical Expenditure Panel Survey

INTRODUCTION

The use of mail-order pharmacies is generally associated with lower healthcare costs and improved medication adherence. To promote the use of mail-order pharmacies, it is important to understand the time trends in their use and whether these trends vary by population subgroups.

METHODS

This study used the 1996-2018 Medical Expenditure Panel Survey to determine the annual prevalence of mail-order pharmacy use (defined as purchasing ≥1 prescription from a mail-order or online pharmacy) among U.S. adult prescription users and its variation by population characteristics. Logistic regression was used to determine the correlates of mail-order pharmacy use. Results were presented for medications and therapeutic classes most commonly purchased by mail-order pharmacy exclusive users. Analyses were conducted in December 2020.

RESULTS

The annual prevalence of mail-order pharmacy use among U.S. adult prescription users increased from 10.2% (95% CI=9.3, 11.1) in 1996 to 17.0% (95% CI=15.9, 18.1) in 2005 and then declined to 15.7% (95% CI=14.9, 16.6) by 2018. Absolute differences in the prevalence of use by race/ethnicity, education, and health insurance coverage widened over time, whereas they remained stable when stratifying by sex, age, marital status, region, limitations in daily activities, pain interference, health status, number of chronic conditions, and access to medical care. Among mail-order pharmacy exclusive users, the 3 most commonly purchased medications were atorvastatin (16.7%), levothyroxine (13.6%), and lisinopril (13.1%); the 3 most commonly purchased therapeutic classes were cardiovascular agents (57.9%), metabolic agents (52.1%), and central nervous system agents (29.6%).

CONCLUSIONS

The prevalence of mail-order pharmacy use has declined in recent years and has shown significant variation across population subgroups. Future research should examine whether the declining trends and variation in use may influence the management of chronic conditions and the disparities in health and healthcare costs.

Effect of the ExactCare medication care management model on adherence, health care utilization, and costs

BACKGROUND: Multimorbidity and polypharmacy are common in the United States and are associated with greater risk of disease-related complications and higher health care costs. ExactCare has implemented a high-touch approach that includes home visits, comprehensive ongoing medication reviews, patient education, medication reconciliation, medication compliance packaging, and electronic reminders and trackers. OBJECTIVE: To test whether the ExactCare program improves medication adherence and reduces health care utilization and costs. METHODS: Using a national database from a large U.S. insurer, we identified Medicare Advantage plan members in 8 states from 2007 to 2018 who had both medical and prescription drug coverage. The index year for an ExactCare patient was identified using the date of the first prescription filled by ExactCare, with the previous year being the baseline. All patients without a prescription from an ExactCare pharmacy were considered potential comparison patients. To propensity match ExactCare and comparison patients, the probability of ExactCare participation was modeled using a logistic regression based on demographics, state, year, urban status, Medicaid eligibility, low-income subsidies, comorbidities, and baseline utilization and costs. Multivariate regression analysis was conducted to generate a difference-in-differences estimate of program effect for the matched pairs as well as patient-level fixed effects, while adjusting for additional time-varying characteristics. Adherence outcomes included the proportion of days covered for oral diabetic medications, antihypertensives, and hydroxymethylglutaryl-coenzyme A reductase inhibitors (statins). Utilization outcomes included emergency department (ED) visits, hospitalizations, and skilled nursing facility (SNF) admissions, hospitalization days, and SNF days. Cost outcomes included total cost of care, prescription drug cost, hospital inpatient cost, and SNF cost. RESULTS: ExactCare patients (N = 701) were propensity-matched to comparison patients (N = 1,395) using the nearest 1:2 match approach, with an average follow-up period of 6.6 and 5.4 years for ExactCare and comparison patients, respectively. One year of ExactCare participation was associated with statistically significant increases in adherence to statins (8.4 percentage points; P < 0.001) and antihypertensive drugs (4.9 percentage points; P < 0.001), but the increase in adherence for diabetes drugs was not statistically significant. ExactCare participation was associated with statistically significant decreases in SNF admission rates (-67 SNF stays per 1,000 member-years; P = 0.011), inpatient days (-857 days per 1,000 member-years; P = 0.022), and SNF days (-1,801 days per 1,000 member-years; P = 0.002), but not with the rates of ED visits or hospital admissions. Each year of ExactCare participation was associated with increases in prescription drug costs ($30 per-member per month [PMPM]; P = 0.006) and decreases in total costs (-$196 PMPM; P = 0.023) and medical costs (-$226 PMPM; P = 0.008), largely attributable to decreases in hospital inpatient costs (-$119 PMPM; P = 0.001) and SNF costs (-$30 PMPM; P = 0.007). CONCLUSIONS: ExactCare's medication care management model was associated with improved medication adherence and an approximately $2,400 per member per year reduction in total cost of care, representing a 5% reduction in average costs. DISCLOSURES: This study was funded by ExactCare Pharmacy under a contract with RAND that grants the study authors sole responsibility for data management, study design, data analysis, manuscript drafting, and the decision to publish. The sponsor had no role in the study design and manuscript drafting. All data analysis was conducted by the study authors. A draft manuscript was reviewed by the sponsor, but the study authors made final decisions regarding the content and study conclusions. Shetty, Chen, and Liu are employed by RAND. Rose has nothing to disclose.

A Randomized Encouragement Trial to Increase Mail Order Pharmacy Use and Medication Adherence in Patients with Diabetes

BACKGROUND

Mail order pharmacy (MOP) use has been linked to improved medication adherence and health outcomes among patients with diabetes. However, no large-scale intervention studies have assessed the effect of encouraging MOP use on medication adherence.

OBJECTIVE

To assess an intervention to encourage MOP services to increase its use and medication adherence.

DESIGN

Randomized encouragement trial.

PATIENTS

63,012 diabetes patients from three health care systems: Kaiser Permanente Northern California (KPNC), Kaiser Permanente Hawaii (KPHI), and Harvard Pilgrim Health Care (HPHC) who were poorly adherent to at least one class of cardiometabolic medications and had not used MOP in the prior 12 months.

INTERVENTION

Patients were randomized to receive either usual care (control arm) or outreach encouraging MOP use consisting of a mailed letter, secure email message, and automated telephone call outlining the potential benefits of MOP use (intervention arm). HPHC intervention patients received the letter only.

MEASUREMENTS

We compared the percentages of patients that began using MOP and that became adherent to cardiometabolic medication classes during a 12-month follow-up period. We also conducted a race/ethnicity-stratified analysis.

RESULTS

During follow-up, 10.6% of intervention patients began using MOP vs. 9.3% of controls (p < 0.01); the percent of cardiometabolic medication delivered via mail was 42.1% vs. 39.8% (p < 0.01). Metformin adherence improved in the intervention arm relative to control at the two KP sites (52% vs. 49%, p < 0.01). Stratified analyses suggested a significant positive effect of the intervention in White (RR: 1.12, 95% CI: 1.03, 1.22) and Asian (RR: 1.30, 95% CI: 1.17, 1.45) patients.

CONCLUSION

This pragmatic trial showed that simple outreach to encourage MOP modestly increased its use and improved adherence measured by refills to a key class of diabetes medications in some settings. Given its minimal cost, clinicians and health systems should consider outreach interventions to actively promote MOP use among diabetes patients.

TRIAL REGISTRATION

ClinicalTrials.gov registration number: NCT02621476.

Trends in Mail-Order Prescription Use among U.S. Adults from 1996 to 2018: A Nationally Representative Repeated Cross-Sectional Study

BACKGROUND

Mail-order prescriptions are popular in the U.S., but the recent mail delays due to operational changes at the United States Postal Services (USPS) may postpone the delivery of vital medications. Despite growing recognition of the health and economic effects of a postal crisis on mail-order pharmacy consumers, little is known about the extent of mail-order prescription use, and most importantly, the population groups and types of medications that will likely be most affected by these postal delays.

METHODS

The prevalence of mail-order prescription use was assessed using a nationally representative repeated cross-sectional survey (the Medical Expenditure Panel Survey) carried out among adults aged 18 and older in each year from 1996 to 2018. We stratified use of mail-order prescription by socio-demographic and health characteristics. Additionally, we calculated which prescription medications were most prevalent among all mailed medications, and for which medications users were most likely to opt for mail-order prescription.

FINDINGS

500,217 adults participated in the survey. Between 1996 and 2018, the prevalence of using at least one mail-order prescription in a year among U.S. adults was 9.8% (95% CI, 9.5%-10.0%). Each user purchased a mean of 19.4 (95% CI, 19.0-19.8) mail-order prescriptions annually. The prevalence of use increased from 6.9% (95% CI, 6.4%-7.5%) in 1996 to 10.3% (95% CI, 9.7%-10.9%) in 2018, and the mean annual number of mail-order prescriptions per user increased from 10.7 (95% CI, 9.8-11.7) to 20.5 (95% CI, 19.3-21.7) over the same period. Use of mail-order prescription in 2018 was common among adults aged 65 and older (23.9% [95% CI, 22.3%-25.4%]), non-Hispanic whites (13.6% [95% CI, 12.8%-14.5%]), married adults (12.7% [95% CI, 11.8%-13.6%]), college graduates (12.2% [95% CI, 11.3%-13.1%]), high-income adults (12.6%, [95% CI, 11.6%-13.6%]), disabled adults (19.3% [95% CI, 17.9%-20.7%]), adults with poor health status (15.6% [95% CI, 11.6%-19.6%]), adults with three or more chronic conditions (24.2% [95% CI, 22.2%-26.2%]), Medicare beneficiaries (22.8% [95% CI, 21.4%-24.3%]), and military-insured adults (13.9% [95% CI, 10.8%-17.1%]). Mail-order prescriptions were commonly filled for analgesics, levothyroxine, cardiovascular agents, antibiotics, and diabetes medications.

INTERPRETATION

The use of mail-order prescription, including for critical medications such as insulin, is increasingly common among U.S. adults and displays substantial variation between population groups. A national slowdown of mail delivery could have important health consequences for a considerable proportion of the U.S. population, particularly during the current Coronavirus disease 2019 epidemic.

Assessment of Consolidated Mail Outpatient Pharmacy Utilization in the Indian Health Service

BACKGROUND

The Indian Health Service (IHS) has an agreement with the US Department of Veterans Affairs (VA) that allows IHS to use the VA Consolidated Mail Outpatient Pharmacy (CMOP) to send prescriptions to IHS patients. However, there is high variability among IHS facilities in the use of CMOP. Furthermore, there is no available resource that summarizes the relative positives/negatives, challenges/opportunities, and strengths/weaknesses of implementing CMOP.

METHODS

A 10-item questionnaire was developed to collect information on various aspects of prescription processing through CMOP. The questionnaire was distributed among the primary CMOP contacts of IHS facilities between December 2018 and January 2019.

RESULTS

The CMOP contacts at 44 of 94 (47%) IHS sites responded to the survey. Of the 347 respondents, 310 (89%) pharmacists were trained in CMOP prescription processing. To get information about CMOP rejections, 53% (185/347) of pharmacists check electronic messages. Twelve (27%) sites utilize technicians in some capacity in the CMOP process. Of the 16 facilities that require patients to request prescriptions to be mailed for each refill request, 8 (50%) do not use any method to designate a CMOP patient. Three sites (7%) have measured patient satisfaction with the CMOP program. Thirteen sites (31%) reported that they are losing insurance reimbursements by using CMOP. The decrease in insurance reimbursements, lengthy prescription processing time, and medication backorders are the most common challenges shared by respondents.

CONCLUSIONS

CMOP presents unique challenges to pharmacy workflow but provides many benefits that local pharmacy mailout programs usually do not possess, such as the ability to mail refrigerated items. Furthermore, it is likely that local programs that utilize mail delivery will increase pharmacy workload. However, there is a lack of objective data to assess the net effect of CMOP on patients. Nevertheless, the successful implementation of CMOP can lead to reduced pharmacy workload while increasing access to care for patients with transportation issues.

Evaluation of Pharmacy Model in a Trial of Free Essential Medicine Access

Background: In Canada, pharmacists accessing electronic health records (EHR) and mailing medications to patients are relatively uncommon. We evaluated a pharmacy model implemented in a clinical trial that combined allowing the pharmacist access to patients' EHR and mailing medications to participants. Methods: We conducted thematic analysis of comments made by participants and prescribers, and chart stimulated recalls with the pharmacist involved with the novel pharmacy model implemented in a clinical trial. Results: Major themes from participant's comments related to the ease of obtaining information about medications from the pharmacy and satisfaction with the delivery. Prescribers felt that this model facilitated collaboration with the pharmacist and welcomed suggestions regarding therapeutic medication changes. Major themes from the pharmacist's chart stimulated recalls were that access to participants' EHRs allowed for improved drug therapy management and participant experience, and this pharmacy model increased participant's access to pharmacy services. Discussion: According to the pharmacist and prescribers, this pharmacy model facilitated their collaboration in prescribing appropriate medications and participants were generally satisfied with the delivery of medications. Conclusion: Participants and prescribers were generally supportive of a pharmacy model that combined allowing the pharmacist access to participants' EHR and medication mailing. This allowed the pharmacist more opportunities for drug therapy management and collaboration with prescribers. It also improved the participant's access to pharmacy services, although those services were not always fully utilized.

Internet-based pharmacy and centralised dispensing: an exploratory mixed-methods study of the views of family practice staff

OBJECTIVES

Over the last decade, technological advances, market competition and increasing pressures for efficiencies across healthcare systems have resulted in changes to the processes and policies involved in medicines prescribing and dispensing. The aim of this study was to explore the views of family practice staff, including GPs, on the perceived impact of changes associated with remote dispensing and the increasing availability of distance-selling pharmacies.

METHODS

Exploratory mixed-methods study using qualitative focus groups and an online cross-sectional survey distributed to a non-probability sample of staff from family practices across England. Survey items were developed based on existing literature and initial thematic analysis from the focus groups and adapted using cognitive interviewing techniques.

KEY FINDINGS

Findings suggest that family practice staff believe that where and how prescriptions are dispensed impacts on their practice and patients. Frequent contact with distance-selling pharmacies is not common; however, highlighted concerns included patient safety issues and the potential threat to the loss of valued elements and sustainability of community pharmacy and dispensing practices. Identified concerns and experiences are unlikely to be routinely discussed within or between practices, limiting opportunities for shared learning and consideration of the potential impact of changes to dispensing processes and policies.

CONCLUSIONS

Further research is needed to confirm these exploratory findings, due to the low response rate and sample size. Findings, nevertheless, highlight how wider changes in dispensing processes may have unintended consequences on other aspects of the healthcare system.

Opportunities to encourage mail order pharmacy delivery service use for diabetes prescriptions: a qualitative study

Background

Medication non-adherence is a major contributor to poor outcomes in diabetes. Previous research has shown an association between use of mail order pharmacy delivery and better medication adherence, but little is known about the barriers and facilitators to mail order pharmacy use in diabetes patients. This qualitative study examined factors related to mail order pharmacy use versus traditional “brick and mortar” pharmacies to refill prescriptions.

Methods

We conducted four 90-min focus groups in 2016 among 28 diabetes patients in the Hawaii and Northern California regions of Kaiser Permanente, a large integrated health care delivery system. We queried participants on their preferred mode for refilling prescriptions and perceived barriers and facilitators of mail order pharmacy use. One researcher independently coded each focus group transcript, with two of these transcripts double-coded by a second researcher to promote reliability. We employed thematic analysis guided by the Capability, Opportunity, Motivation, and Behavior (COM-B) framework using NVivo 11 software.

Results

A total of 28 diabetes patients participated. Participants’ average age was 64.1 years; 57% were female; and racial/ethnic backgrounds included Asian/Native Hawaiian/Pacific Islander (36%), Black/African-American (21%) Hispanic/Latino (7%), and non-Hispanic White (36%). Analysis uncovered 26 themes related to the decision to use mail order pharmacy, with each theme representing a barrier or facilitator mapped to the COM-B framework. Most themes (20/26) fell into the COM-B category of ‘Opportunity.’ Opportunity barriers to mail order pharmacy use included unpredictability of medication delivery date, concerns about mail security, and difficulty coordinating refill orders for multiple prescriptions. In contrast, facilitators included greater access and convenience (e.g., no need to wait in line or arrange transportation) compared to traditional pharmacies. Motivational facilitators to mail order pharmacy use included receiving a pharmacy benefit plan incentive of a free one-month supply of prescriptions.

Conclusions

This study found that while patients with diabetes may benefit from mail order pharmacy use, they perceive numerous barriers to using the service. These findings will inform the design of interventions and quality improvement initiatives to increase mail order pharmacy use, which in turn may improve medication adherence and outcomes in diabetes patients, across health care systems.

A Retrospective Database Study Comparing Diabetes-Related Medication Adherence and Health Outcomes for Mail-Order Versus Community Pharmacy

BACKGROUND

Adherence to oral antihyperglycemic agents (AHAs) is important for managing blood glucose levels and avoiding hospitalizations or diabetes complications. Previous studies have found that use of mail-order pharmacy dispensing channels results in greater adherence than use of community pharmacies, but the link between use of mail-order pharmacies and improved clinical outcomes has not been established.

OBJECTIVE

To compare the effect of mail-order and community pharmacy use on adherence to oral AHAs, hemoglobin A1c (A1c) level, and glycemic control, as well as emergency department (ED) and inpatient hospital use.

METHODS

This retrospective cohort study of administrative claims data from January 1, 2008, to December 31, 2016, included patients with Medicare Advantage Prescription Drug plan coverage with ≥ 2 claims for the same oral AHA and a diagnosis of type 2 diabetes mellitus (T2DM). Patients were indexed to the start of the most advanced oral AHA identified to begin study observations at the start of a new treatment and assigned to mail-order or community pharmacy cohorts based on which channel dispensed ≥ 80% of their oral AHA claims; all others were excluded. Mail-order and community pharmacy patients were 1:1 propensity score matched. Matched cohorts were compared on proportion of days covered (PDC), adherence (PDC ≥ 0.8), A1c level, glycemic control, and ED and inpatient use for measurement periods of 12, 24, 36, and 48 months post-index.

RESULTS

19,307 mail-order and 19,307 community pharmacy users were matched. PDC was higher for mail-order pharmacy users at 12 months (0.93 vs. 0.82, P < 0.001) and sustainable through 48 months (0.87 vs. 0.77, P < 0.001). Adherence was also greater for mail-order pharmacy patients through 12 months (86% vs. 68%, P < 0.001) and sustainable through 48 months (78% vs. 62%, P < 0.001). Glycemic control as A1c < 7% was not significantly different, but control as A1c < 8% was greater for mail-order pharmacy users at 12 months (91% vs. 89%, P = 0.006) and was greater through 36 months (93% vs. 89%, P = 0.043). Effects on A1c level were not evident. Mail-order pharmacy users were less likely to have an ED visit within 12 months (26% vs. 28%, P < 0.0001), and the difference was observed through 36 months (50% vs. 54%, P < 0.0001). Similarly, fewer mail-order pharmacy users had an inpatient hospitalization within 12 months (17% vs. 19%, P < 0.0001), and the difference was observed through 48 months (43% vs. 47%, P = 0.009).

CONCLUSIONS

The results of the study demonstrate a benefit to patients who use mail-order pharmacies for chronic medications to treat T2DM. The study identified greater glycemic control, lower ED use, and lower hospitalization among individuals using mail-order pharmacies. These positive outcomes were evident in the near term and sustained over time.

Characteristics of Mail-Order Pharmacy Users: Results From the Medical Expenditures Panel Survey

BACKGROUND

There is a paucity of research on the population characteristics of mail-order pharmacy users.

OBJECTIVE

This study utilized a nationally representative sample to examine the characteristics of mail-order pharmacy users.

METHODS

This study used data from the 2012 Medical Expenditure Panel Survey (MEPS). The outcome variable was defined as whether the participant had used a mail-order pharmacy during the study year. Logistic regression was conducted to determine the factors which influence mail-order pharmacy use. All analyses incorporated MEPS sampling weights to adjust for the complex survey design.

RESULTS

Among the 14,106 adults included, approximately 18% of them had used a mail-order pharmacy at least once to fill their prescription in 2012. Compared to community pharmacy users, mail-order pharmacy users were more likely to be white, older, married, have a higher family income, a higher educational level, have health insurance, and have a prescription with at least a 30-day supply. There is no difference in gender or urban/rural disparity. In addition, mail-order pharmacy users had a lower percentage of out-of-pocket costs.

CONCLUSION

Mail-order pharmacy use was significantly associated with certain patient characteristics. Policymakers should consider these characteristics when promoting mail-order pharmacy use.

Teleconsultation for the Pharmaceutical Care of HIV Outpatients in Receipt of Home Antiretrovirals Delivery: Clinical, Economic, and Patient-Perceived Quality Analysis

Background/Introduction: Pharmacist teleconsultations, combined with home drug delivery or mail-order pharmacy (MOP), can help hospital outpatients with difficulties accessing treatment. The objectives of this study are to describe a teleconsultation protocol and to evaluate clinical, economic, and patient-perceived quality results. Materials and Methods: A cohort observational study was carried out for 3 years on HIV outpatients. Clinical variables were adherence, plasma HIV-RNA, and CD4+ levels. A pharmacoeconomic analysis was carried out through a cost-minimization study. Patient-perceived quality was assessed through a satisfaction survey. Simple random sampling was performed for 95% safety, accuracy ±1%, and losses ±20%. Results: The 38 participants (sample size) consisted of 82% male patients, aged 44.7 ± 8.4 years. There were 854 teleconsultations and 100% treatment adherence. All HIV outpatients kept virally suppressed (p = 1.00) and maintained a controlled immunological level (p = 0.87). The economic evaluation revealed 137 ± 23 € patient/year costs-saved and 18.5 ± 7.2 h/patient/year working time gained. Patient-perceived quality average score was >9.4 out of 10 in all items; the most valued factors were the saving of direct costs and reconciliation with work commitments (45%) and the least valued attributes were making the payment for the shipment and having to adjust to a telephone appointment (41%). Discussion/Conclusions: A teleconsultation protocol associated with home antiretrovirals delivery or MOP obtains a high degree of satisfaction from the HIV hospital outpatients receiving treatment, without repercussions on the therapeutic objectives and with the saving of important direct costs for the patient and indirect costs in relation to labor productivity.

Mail order pharmacy use and adherence to secondary prevention drugs among stroke patients

BACKGROUND AND PURPOSE

Mail order pharmacies (MOP) are increasingly being used to deliver medications for chronic disease management. Their use is linked to similar or even greater medication adherence than local pharmacy (LP) use. We are unaware of any studies that have evaluated the association of mail order pharmacy use with drug adherence among stroke patients.

METHODS

We conducted cross-sectional analyses of patients discharged with ischemic stroke from 24 hospitals in a managed care network, who received a new anticoagulant, antiplatelet, anti-glycemic, antihypertensive, and/or lipid-lowering medication between January 1, 2007 and June 30, 2015. We defined good adherence as medication availability ≥80% of the time, and compared adherence between mail-order users (≥66% of refills by mail) and local pharmacy users (all refills in person). Relationship between delivery method and adherence was evaluated using multivariate regression models.

RESULTS

A total of 44,658 eligible patients refilled an index medication. Of these, 13,295 in the LP and 6801 in MOP groups met inclusion criteria. Patients in the MOP group were more likely to be white, and less likely to have hypertension, diabetes, and smoke tobacco. Continuous Medication Gap (CMG) adherence was 0.28 in the LP group and 0.11 in the MOP group (p < 0.001). At 90-days there were 893 hospital readmissions for the LP group and 375 for the MOP group for a rate of 0.07 vs 0.06 (p < 0.001). In the multivariable analysis, adherence was associated with MOP use, (OR 0.12, 95% CI 0.11-0.14) and decreased readmission at 90 days (OR 0.62, 95% CI 0.55-0.71).

CONCLUSIONS

Stroke patients who use MOP vs. LP are more likely to have good medication adherence. Future studies should examine the impact of mail-order pharmacy use on vascular risk marker control and events after stroke.

Examination of the Link Between Medication Adherence and Use of Mail-Order Pharmacies in Chronic Disease States

BACKGROUND

Higher medication adherence is associated with positive health outcomes, including reduction in hospitalizations and costs, and many interventions have been implemented to increase patient adherence.

OBJECTIVES

To determine whether patients experience higher medication adherence by using mail-order or retail pharmacies.

METHODS

Articles pertaining to retail and mail-order pharmacies and medication adherence were collected from 3 literature databases: MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and International Pharmaceutical Abstracts (IPA). Searches were created for each database and articles were compiled. Articles were screened for exclusion factors, and final articles (n=15) comparing medication adherence in patients utilizing mail and retail pharmacies were analyzed. For each study, various factors were identified including days supply, patients' out-of-pocket costs, prior adherence behavior, therapeutic class, measure of adherence, limitations, and results. Studies were then categorized by disease state, and relevant information from each study was compared and contrasted.

RESULTS

The majority of studies-14 out of the 15 reviewed-supported higher adherence through the mail-order dispensing channel rather than through retail pharmacies. There are a number of reasons for the differences in adherence between the channels. Study patients who used mail-order pharmacies were more likely to have substantially higher prior adherence behavior, socioeconomic status, and days supply of medicines received and were likely to be offered financial incentives to use mail-order. The few studies that attempted to statistically control for these factors also found that patients using mail-order services were more adherent but the size of the differences was smaller. The extent to which these results indicate an inherent adherence advantage of mail-order pharmacy (as distinct from adherence benefits due to greater days supply, lower copays, or more adherent patients selecting mail-order pharmacies) depends on how well the statistical controls adjusted for the substantial differences between the mail and retail samples.

CONCLUSIONS

While the research strongly indicates that consumers who use mail-order pharmacies are more likely to be adherent, more research is needed before it can be conclusively determined that use of mail-order pharmacies causes higher adherence.

Direct-to-Consumer Sale of Prescription Drugs by Pharmaceutical Companies

Background. Direct-to-consumer sale of prescription medications by pharmaceutical companies has emerged as a novel delivery method. It is important to ensure that patients who choose this method are receiving adequate pharmaceutical care that meets established practice standards. Objective. The objective of this study was to assess consultation for patients who are receiving medications via direct-to-consumer sales of prescription drugs from pharmaceutical companies. Methods. We conducted a blinded telephone survey using 10 mock prescriptions for simulated patients (secret shoppers) by contacting the 2 companies currently offering prescription medications for sale directly to consumers. Results. Simulated patients in this pilot study only had a pharmacist initiate consultation for 20% of the calls. Multiple pharmacy technicians offered consultation and this behavior does not follow state statutes. In addition, technicians also failed to forward calls to the pharmacist-on-duty, instead suggesting the patients contact their physicians. On a further direct request to speak to a pharmacist, a consultation did occur for 90% of the calls. However, the consultation failed to achieve practice standards set by Omnibus Budget Reconciliation Act of 1990 and the state statutes for the majority of the encounters. Conclusion. These results warrant a larger scale study of consultation for direct-to-consumer prescription sales. In addition, they highlight areas for training needed for all pharmacy personnel who work in this venue.

Impact of a Novel Cost-Saving Pharmacy Program on Pregabalin Use and Health Care Costs

BACKGROUND

Pharmacy cost-saving programs often aim to reduce costs for members and payers by encouraging use of lower-tier or generic medications and lower-cost sales channels. In 2010, a national U.S. health plan began a novel pharmacy program directed at reducing pharmacy expenditures for targeted medications, including pregabalin. The program provided multiple options to avoid higher cost sharing: use mail order pharmacy or switch to a lower-cost alternative medication via mail order or retail. Members who did not choose any option eventually paid the full retail cost of pregabalin.

OBJECTIVE

To evaluate the impact of the pharmacy program on pregabalin and alternative medication use, health care costs, and health care utilization.

METHODS

This retrospective analysis of claims data included adult commercial health plan members with a retail claim for pregabalin in the first 13 months of the pharmacy program (identification [ID] period: February 1, 2010-February 28, 2011). Members whose benefit plan included the pharmacy program were assigned to the program cohort; all others were assigned to the nonprogram cohort. The program cohort index date was the first retail pregabalin claim during the ID period and after the program start; the nonprogram cohort index date was the first retail pregabalin claim during the ID period. All members were continuously enrolled for 12 months pre- and post-index and had at least 1 inpatient claim or ≥ 2 ambulatory visit claims for a pregabalin-indicated condition. Cohorts were propensity score matched (PSM) 1:1 with logistic regression on demographic and pre-index characteristics, including mail order and pregabalin use, comorbidity, health care costs, and health care utilization. Pregabalin, gabapentin and other alternative medication use, health care costs, and health care utilization were measured. The program cohort was also divided into 2 groups: members who changed to gabapentin post-index and those who did not. A difference-in-differences (DiD) analysis was used to compare the between-cohort change in pregabalin and alternative medication use patterns, health care costs, and health care resource utilization from pre- to post-index. The within-cohort change from pre- to post-index was analyzed by McNemar's test (categorical variables) or paired t-test (continuous variables). The Rao-Scott chi-square test (categorical) and general estimating equations (continuous) were used to analyze between-cohort differences at each time point. Differences in program member characteristics of those who changed versus those who did not change to gabapentin post-index were assessed by traditional chi-square test (categorical) or two-sample t-test (continuous variables).

RESULTS

A total of 1,218 members in each cohort were PSM. Mean age was 51 years, 76.7% were women, and the most common pregabalin-indicated condition was fibromyalgia (77.6%). After the program start, the mean number of pregabalin claims from mail order and retail combined decreased in the program cohort from 4.7 pre-index to 3.8 post-index, and increased in the nonprogram cohort from 4.7 pre-index to 6.2 post-index (DiD, P < 0.001). Pregabalin mail order use increased from 3.1% to 48.1% of program members versus 2.8% to 9.4% of nonprogram members (DiD, P < 0.001). Program members were also more likely to change to the anticonvulsant gabapentin post-index than were nonprogram members (31.0% vs. 15.9%, P < 0.001). Mean total health care costs were similar between cohorts, and the pre- to post-index change did not differ between cohorts (DiD, P = 0.474). However, mean total pharmacy costs rose from pre-index to post-index by $820 and $790 in the program and nonprogram cohorts, respectively (both P < 0.001); the increase was similar between cohorts (DiD, P = 0.888). Program members who changed to gabapentin had a higher mean comorbidity score (P = 0.001) and greater post-index use of opioids, alternative medications, and health care resources (P < 0.050) than program members who did not change to gabapentin.

CONCLUSIONS

The pharmacy program increased mail order use of pregabalin but reduced pregabalin claims from any venue. Program members were more likely to change to gabapentin than were nonprogram members, and those who changed had higher comorbidity, use of alternative medication, and health care resources. Despite increased mail order use for pregabalin and greater change to gabapentin by program members, the pharmacy program was not cost saving with respect to mean pharmacy or total health care costs.

Patterns of use and expenses associated with mail-service pharmacy in adults with diabetes

OBJECTIVES

To identify socioeconomic factors associated with mail-service pharmacy use and compare the differences in disease-specific prescription medication and medical utilization expenses in a nationally representative sample of adults with diabetes.

DESIGN

A retrospective, longitudinal, cross-sectional study.

SETTING

United States in 2006-11.

PARTICIPANTS

Medical Expenditure Panel Survey household component (MEPS-HC) participants aged 18 years or older diagnosed with diabetes and prescribed antidiabetic medications.

MAIN OUTCOME MEASURES

Likelihood of mail-service pharmacy use, diabetes-related medical utilization, and medication expenses.

RESULTS

Among 4,430 eligible participants identified in the 2006-11 surveys, representing more than 83 million U.S. individuals, nearly 13% of the participants obtained two-thirds or more of their antidiabetic medications via mail service predominantly. Mail-service pharmacy users were older, had high school or college degrees, had higher incomes, and were more likely to be covered by private insurance. There were no significant differences in diabetes-related medical utilization and drug expenses between the two groups.

CONCLUSION

Besides pharmacy benefit design, sociodemographic and economic factors influenced drug dispensing channel use (mail service versus community pharmacy). No significant differences in diabetes-related drug and medical expenses between mail-service and community pharmacy users were observed.

Understanding adherence to medications in type 2 diabetes care and clinical trials to overcome barriers: a narrative review

AIM

To identify factors affecting adherence to medications in type 2 diabetes (T2D) care and clinical trials.

BACKGROUND

Adherence to medication is associated with better patient outcomes, lower healthcare costs, and improved quality and robustness of trial data. In T2D, non-adherence to regimens may compromise glycemic, blood pressure and lipid control, which can, in turn, increase morbidity and mortality rates.

DESIGN

A literature search was performed to identify studies reporting adherence to medications and highlighting specific adherence challenges/approaches in T2D. The search was limited to clinical trials, comparative studies or meta-analyses, reported in English with a freely available abstract.

DATA SOURCE

MEDLINE (31 December 2008 to 31 December 2013).

REVIEW METHODS

Studies not reporting adherence to medications or highlighting adherence challenges/approaches in T2D, presenting only self-reported adherence or including fewer than 100 patients were excluded. Eligible reports are discussed narratively.

RESULTS

Factors identified as having a detrimental impact on adherence were smoking, depression and polypharmacy. Conversely, increased convenience (e.g. pen compared with vial and syringe; medication supplied by mail order vs. retail pharmacy) was associated with better patient adherence, as were interventions that increased patient motivation (e.g. individualized, nurse-led consultation) and education.

CONCLUSIONS

Medication adherence is influenced by complex and multifactorial issues, which can include smoking, depression, polypharmacy, convenience of obtaining and administering the medication, patient motivation and education. We recommend simplifying treatment regimens, where possible, improving provider-patient communication, and providing support and education to increase medication adherence, with a view to improving patient outcomes and clinical trial data quality.

Medication Adherence With Diabetes Medication: A Systematic Review of the Literature

PURPOSE

The primary purpose of this systematic review is to synthesize the evidence regarding risk factors associated with nonadherence to prescribed glucose-lowering agents, the impact of nonadherence on glycemic control and the economics of diabetes care, and the interventions designed to improve adherence.

METHODS

Medline, EMBASE, the Cochrane Collaborative, BIOSIS, and the Health and Psychosocial Instruments databases were searched for studies of medication adherence for the period from May 2007 to December 2014. Inclusion criteria were study design and primary outcome measuring or characterizing adherence. Published evidence was graded according to the American Association of Clinical Endocrinologists protocol for standardized production of clinical practice guidelines.

RESULTS

One hundred ninety-six published articles were reviewed; 98 met inclusion criteria. Factors including age, race, health beliefs, medication cost, co-pays, Medicare Part D coverage gap, insulin use, health literacy, primary nonadherence, and early nonpersistence significantly affect adherence. Higher adherence was associated with improved glycemic control, fewer emergency department visits, decreased hospitalizations, and lower medical costs. Adherence was lower when medications were not tolerated or were taken more than twice daily, with concomitant depression, and with skepticism about the importance of medication. Intervention trials show the use of phone interventions, integrative health coaching, case managers, pharmacists, education, and point-of-care testing improve adherence.

CONCLUSION

Medication adherence remains an important consideration in diabetes care. Health professionals working with individuals with diabetes (eg, diabetes educators) are in a key position to assess risks for nonadherence, to develop strategies to facilitate medication taking, and to provide ongoing support and assessment of adherence at each visit.

Development, test-retest reliability and validity of the Pharmacy Value-Added Services Questionnaire (PVASQ)

Objective:

(i) To develop the Pharmacy Value-Added Services Questionnaire (PVASQ) using emerging themes generated from interviews. (ii) To establish reliability and validity of questionnaire instrument.

Methods:

Using an extended Theory of Planned Behavior as the theoretical model, face-to-face interviews generated salient beliefs of pharmacy value-added services. The PVASQ was constructed initially in English incorporating important themes and later translated into the Malay language with forward and backward translation. Intention (INT) to adopt pharmacy value-added services is predicted by attitudes (ATT), subjective norms (SN), perceived behavioral control (PBC), knowledge and expectations. Using a 7-point Likert-type scale and a dichotomous scale, test-retest reliability (N=25) was assessed by administrating the questionnaire instrument twice at an interval of one week apart. Internal consistency was measured by Cronbach’s alpha and construct validity between two administrations was assessed using the kappa statistic and the intraclass correlation coefficient (ICC). Confirmatory Factor Analysis, CFA (N=410) was conducted to assess construct validity of the PVASQ.

Results:

The kappa coefficients indicate a moderate to almost perfect strength of agreement between test and retest. The ICC for all scales tested for intra-rater (test-retest) reliability was good. The overall Cronbach’ s alpha (N=25) is 0.912 and 0.908 for the two time points. The result of CFA (N=410) showed most items loaded strongly and correctly into corresponding factors. Only one item was eliminated.

Conclusions:

This study is the first to develop and establish the reliability and validity of the Pharmacy Value-Added Services Questionnaire instrument using the Theory of Planned Behavior as the theoretical model. The translated Malay language version of PVASQ is reliable and valid to predict Malaysian patients’ intention to adopt pharmacy value-added services to collect partial medicine supply.

A review of the methodological challenges in assessing the cost effectiveness of pharmacist interventions

Pharmacists' roles are shifting away from medicines supply and the provision of patient education involving acute medications towards consultation-type services for chronic medications. Determining the cost effectiveness of pharmacist interventions has been complicated by methodological challenges. A critique of 31 economic evaluations carried out alongside comparative studies of pharmacist interventions published between 2003 and 2013 (12 from the UK, six from the USA) found a range of disease-specific and cross-therapeutic interventions targeting both patients and prescribers in a range of settings evaluated through a variety of study designs. Only ten were full economic evaluations, five of which were based on randomized controlled trials (RCTs). The intervention was usually quite well described, but the comparator was not always clearly described, and some interventions are very context specific due to the variability in pharmacist services available in different countries and practice settings. Complex multidirectional aims of most pharmacist interventions have led to many process, intermediate and longer-term outcomes being included in any one study. Quality of resource use and cost data varied. Most incremental cost-effectiveness ratios (ICERs) were generated from process indicators such as errors and adherence, with only four studies reporting cost per quality-adjusted life-year (QALY). Very few studies examined the effect of uncertainty, and methods used were not very clear in some cases. The principal finding from our critique is that poor RCT study design or analysis precludes many studies from finding pharmacist interventions effective or cost effective. We conclude with a set of recommendations for future study design.

Impact of a pharmacy benefit change on new use of mail order pharmacy among diabetes patients: the Diabetes Study of Northern California (DISTANCE)

OBJECTIVE

To assess the impact of a pharmacy benefit change on mail order pharmacy (MOP) uptake.

DATA SOURCES/STUDY SETTING

Race-stratified, random sample of diabetes patients in an integrated health care delivery system.

STUDY DESIGN

In this natural experiment, we studied the impact of a pharmacy benefit change that conditionally discounted medications if patients used MOP and prepaid two copayments. We compared MOP uptake among those exposed to the benefit change (n = 2,442) and the reference group with no benefit change (n = 8,148), and estimated differential MOP uptake across social strata using a difference-in-differences framework.

DATA COLLECTION/EXTRACTION METHODS

Ascertained MOP uptake (initiation among previous nonusers).

PRINCIPAL FINDINGS

Thirty percent of patients started using MOP after receiving the benefit change versus 9 percent uptake among the reference group (p < .0001). After adjustment, there was a 26 percentage point greater MOP uptake (benefit change effect). This benefit change effect was significantly smaller among patients with inadequate health literacy (15 percent less), limited English proficiency (14 percent less), and among Latinos and Asians (24 and 16 percent less compared to Caucasians).

CONCLUSIONS

Conditionally discounting medications delivered by MOP effectively stimulated MOP uptake overall, but it unintentionally widened previously existing social gaps in MOP use because it stimulated less MOP uptake in vulnerable populations.

Predictors of medication adherence in patients with type 2 diabetes mellitus

OBJECTIVE

Medical professionals are often challenged by lack of patient compliance with pharmaceutical treatments. Research has shown that patients with diabetes have one of the lowest medication adherence rates at 65% to 85%. Some causes have been identified in the literature, but the influence of type of medication is unknown. This study assessed the impact of a broad range of factors on medication adherence and persistence among adult patients with type 2 diabetes mellitus.

METHODS

Patients were selected from the Truven Health MarketScan Research Databases of healthcare administrative claims (2009 through 2012), assigned to mutually exclusive cohorts based on initiation of saxagliptin (a dipeptidyl peptidase-4 [DPP-4] inhibitor), or a glucagon-like peptide 1 (GLP-1) receptor agonist (daily or twice daily formulation), sulfonylurea (SU), or thiazolidinedione (TZD), and screened for continuous enrollment 1 year before and after drug initiation. Adherence and persistence were measured using proportion of days covered and time to discontinuation, respectively. Multivariate models were used to examine the impact of study drug and demographic and clinical factors.

RESULTS

Overall, 45.1% of patients were adherent with their study drug over the 1 year follow-up period. Adherence was higher among patients who were male, older, or residing in non-Southern states. Adherence was better with mail-order use and lower levels of cost sharing. Patients taking a GLP-1 (OR = 0.40, 95% CI = 0.37, 0.42), SU (OR = 0.49, 95% CI = 0.46, 0.52), or TZD (OR = 0.54, 95% CI = 0.51, 0.57) were less likely to be adherent compared with those taking saxagliptin. Results were mixed regarding the impact of comorbidities and polypharmacy on medication adherence. Influencing factors may be the type of comorbidity, overall health level, number of drugs, and complexity of the drug regimen.

KEY LIMITATIONS

Adherence was measured using data for prescriptions dispensed and it is not known whether patients actually took the medications, hence adherence may be overestimated. Whether patients who discontinued the study drugs switched to other diabetes medications or discontinued treatment completely was not measured.

CONCLUSION

Identified risk factors can guide medical professionals in their attempts to increase the likelihood of patient adherence to drug treatment regimens.

Health system factors and antihypertensive adherence in a racially and ethnically diverse cohort of new users

BACKGROUND

The purpose of this study was to identify potential health system solutions to suboptimal use of antihypertensive therapy in a diverse cohort of patients initiating treatment.

METHODS

Using a hypertension registry at Kaiser Permanente Northern California, we conducted a retrospective cohort study of 44 167 adults (age, ≥18 years) with hypertension who were new users of antihypertensive therapy in 2008. We used multivariate logistic regression analysis to model the relationships between race/ethnicity, specific health system factors, and early nonpersistence (failing to refill the first prescription within 90 days) and nonadherence (<80% of days covered during the 12 months following the start of treatment), respectively, controlling for sociodemographic and clinical risk factors.

RESULTS

More than 30% of patients were early nonpersistent and 1 in 5 were nonadherent to therapy. Nonwhites were more likely to exhibit both types of suboptimal medication-taking behavior compared with whites. In logistic regression models adjusted for sociodemographic, clinical, and health system factors, nonwhite race was associated with early nonpersistence (black: odds ratio, 1.56 [95% CI, 1.43-1.70]; Asian: 1.40 [1.29-1.51]; Hispanic: 1.46 [1.35-1.57]) and nonadherence (black: 1.55 [1.37-1.77]; Asian: 1.13 [1.00-1.28]; Hispanic: 1.46 [1.31-1.63]). The likelihood of early nonpersistence varied between Asians and Hispanics by choice of first-line therapy. In addition, racial and ethnic differences in nonadherence were appreciably attenuated when medication co-payment and mail-order pharmacy use were accounted for in the models.

CONCLUSIONS

Racial/ethnic differences in medication-taking behavior occur early in the course of treatment. However, health system strategies designed to reduce patient co-payments, ease access to medications, and optimize the choice of initial therapy may be effective tools in narrowing persistent gaps in the use of these and other clinically effective therapies.

[Therapeutic non-compliance with insulin in the treatment of diabetes mellitus 2]

OBJECTIVE

To determine the percentage of therapeutic noncompliance among type 2 diabetes patients on treatment with insulin.

DESIGN

Prospective multicentre study.

SETTING

Nine Primary Care Health Centre in Huelva (Spain).

PARTICIPANTS

A total of 121 type 2 diabetics, who, in the opinion of their doctor, need to start treatment with insulin or have their insulin treatment modified.

MAIN MEASUREMENTS

Five visits were made (enrolment, 6, 12, 18 and 24 months). The variables analysed were, fasting blood glucose, glycosylated haemoglobin, compliance with insulin treatment, measured by counting insulin units. The percentage compliance (PC) was calculated by (PC = Total No. of insulin units expected to be consumed / Total No. of insulin units that should have been taken x 100). A complier was considered as one who achieved a PC between 80 and 100%.

RESULTS

There were 103 evaluable subjects (85.8%) with a mean age of 66.4 (SD 11.6) years, and 45 were male (42.8%). The mean percentage compliance with insulin was 90.9% (95% CI, 84.2-97.6%). At the 6, 12, 18 and 24 months visits it was 92.1% (95% CI, 85.6-98.6%), 92.3, 90.1 and 89.2% (95% CI, 81.7-96.7%), respectively. Overall patient compliance was 74.75% (95% CI, 64.3-85.2%). For the visits, compliance was 82.5% (95% CI, 73.3-91.7%), 77.7%, 73.8% and 71.8% (95% CI, 60.9-82.7%), respectively (P<.05 initial-final).

CONCLUSIONS

A quarter of the diabetic patients did not comply with their insulin treatment.

The comparative effectiveness of mail order pharmacy use vs. local pharmacy use on LDL-C control in new statin users

BACKGROUND

Mail order pharmacies are commonly used to deliver CVD risk factor medications. Previous studies have shown that mail order pharmacy use is associated with greater medication adherence; however, no studies have examined whether mail order pharmacy use is related to improved CVD risk factor outcomes.

OBJECTIVE

To examine the comparative effectiveness of mail order pharmacy vs. local pharmacy use on LDL-C control in new statin users.

DESIGN

Observational cohort study.

PATIENTS

100,298 adult Kaiser Permanente Northern California (KPNC) members who were new users of statins between January 1, 2005 and December 31, 2007.

MEASUREMENTS

The main outcome measure was LDL-C control in the 3-15 month period after statin therapy was initiated.

RESULTS

After adjustment for patient, clinical, and census-block characteristics, and for potential unmeasured differences between mail order and local KPNC pharmacy users with instrumental variables analysis, 85.0% of patients who used the mail order pharmacy to deliver their statin at any time achieved target LDL-C levels compared with 74.2% of patients who only used the local KPNC pharmacy to dispense the statin (p < 0.001). Greater adjusted rates of LDL-C control in mail order pharmacy users were seen across all gender and race/ethnicity subgroups.

CONCLUSIONS

Mail order pharmacy use was positively associated with LDL-C control in new statin users. Future research should continue to explore the relationship between mail order pharmacy use and outcomes, and address how to appropriately target mail order services to patients most likely to benefit without compromising patient choice, care, and safety.

Mail-order pharmacy use and medication adherence among Medicare Part D beneficiaries with diabetes

OBJECTIVE

To examine medication adherence among Medicare Part D beneficiaries initiating oral anti-diabetic medications and explore whether there is any association of using mail-order pharmacy (vs. retail pharmacy) with better adherence in this patient population.

RESEARCH DESIGN AND METHODS

Using administrative pharmacy claims data, we conducted a retrospective cohort study on Medicare Part D beneficiaries who newly initiated oral anti-diabetic treatment between July 1, 2008 and December 31, 2008. Mail-order pharmacy users were matched to retail pharmacy users via propensity scoring, controlling for patient demographic and clinical characteristics. Adherence with oral anti-diabetic medications during the benefit year of 2009 was assessed using the proportion of days covered (PDC). Comparison of medication adherence between the mail-order pharmacy group and retail pharmacy group was conducted in the propensity matched sample using the paired t-tests and McNemar's tests.

RESULTS

A total of 22,546 patients who initiated oral anti-diabetic medications were identified. The average PDC was 0.60 and only 41.6% of the study population attained good adherence (defined as PDC ≥ 0.8) with oral anti-diabetic medications during calendar year 2009. The matched sample included 1361 patients in each of the mail-order and retail pharmacy cohorts. Compared with the retail pharmacy group, mail-order pharmacy users demonstrated a significantly higher PDC (0.68 vs. 0.61; P < 0.001) throughout the benefit year. More patients in the mail-order pharmacy group (49.7%) attained good adherence with their oral anti-diabetic medications compared to 42.8% in the retail pharmacy group (P < 0.001).

LIMITATIONS

The study was subject to limitations inherent in retrospective claims database analysis.

CONCLUSIONS

Adherence with oral anti-diabetic medications among Medicare Part D beneficiaries is suboptimal. Patients using mail-order pharmacy had better adherence to oral anti-diabetic medications than those who used retail pharmacies. However, the causal relationship between mail-order pharmacy use and adherence should be further examined in a randomized study setting.
