Impact of pharmacy services on cystic fibrosis medication adherence

A decade of change: The evolution of pharmacy services at U.S. cystic fibrosis centers

INTRODUCTION

People with cystic fibrosis (pwCF) require a multidisciplinary care team due to disease complexity. The Cystic Fibrosis Foundation (CFF) notes that pharmacists are recommended, while other organizations consider pharmacists required. In 2016, the CFF initiated a grant program for CFF-accredited care centers and affiliate programs (CFF-ACCAP) to implement outpatient pharmacy services. The primary objective of this study was to compare surveys regarding pharmacy involvement in CFF-ACCAP pre- and post-grant implementation.

METHODS

This was an IRB-approved, survey-based study. The surveys were distributed via the CF pharmacist-pharmacy technician and center director e-mail exchanges.

RESULTS

There are currently 244 CFF-ACCAP and 158 pharmacists. Forty-two pharmacists completed the 2013 survey and 77 completed the 2023 survey. Practice site shifted from primarily the inpatient (58.5%) to outpatient settings (67.5%; p < .001). Most positions were created in the past 7 years (81%) with 50% currently or previously funded by the CFF grant program. CFF center director response decreased from 2013 to 2023 (106 vs. 48) but centers with a dedicated CF pharmacist increased from 2013 to 2023 (66%-86%; p = .014). In the 2023 survey, we received responses from 17 pharmacy technicians, who were newly included. Most of these technicians (64%) reported working in outpatient clinics.

CONCLUSIONS

Since 2013, pharmacy presence has grown at CFF-ACCAP, partly due to the CFF grant program. Despite pharmacists not being required members of the multidisciplinary care team, their presence is notable in 65% of CFF-ACCAP centers, where they contribute significantly to improving the care provided for pwCF.

The role of the clinical pharmacist in the respiratory or sleep multidisciplinary team

The role of the pharmacist has evolved significantly, not least over the last 20 years. It delivers a skilled profession with a vital role in medicines optimisation and the management of patients with a respiratory or sleep disorder. While pharmacists are capable of acting as independent practitioners delivering direct patient care, this article explores their contribution to multidisciplinary teams within asthma, COPD, cystic fibrosis, tuberculosis, interstitial lung disease and sleep medicine. Having identified patient cohorts needing specialist medicines support, notably those with poor medicines adherence or specific medicines-related needs (for example during adolescence, or women who are pregnant or breastfeeding), these pharmacists work within primary, secondary and specialist tertiary care. The aim of this review is to share and inspire innovative models of working to include more pharmacists in respiratory and sleep medicine.

Adherence to hydroxyurea and clinical outcomes among children with sickle cell anemia

OBJECTIVE

Hydroxyurea lowers the incidence of vaso-occlusive pain crises (VOC) and acute chest syndrome (ACS) among children with sickle cell anemia (SCA). Our objective was to assess the relationship between levels of adherence to hydroxyurea and clinical outcomes among children and adolescents with SCA.

METHODS

This retrospective cohort study included Medicaid data (2005-2012) from Florida, Illinois, Louisiana, Michigan, South Carolina, and Texas. The study population consisted of children 1-17 years old with SCA enrolled in Medicaid for 3 years. Among children that initiated hydroxyurea, the medication possession ratio (MPR) was calculated as the proportion of days covered by hydroxyurea. Six months after initiation of hydroxyurea, clinical outcomes were assessed through the end of the study period: numbers of VOC-related inpatient admissions and emergency department visits, and encounters for ACS. Multivariable Poisson models were used to predict outcomes by MPR quartile adjusting for previous healthcare utilization, state, and age.

RESULTS

Hydroxyurea was initiated by 515 children. The median MPR was 0.53 (interquartile range = 0.3-0.8). The annual median number of visits was 0.0 for ACS, 1.3 for VOC-related emergency department, and 1.4 for VOC-related inpatient admissions. For each outcome, the highest quartile of MPR had the lowest predicted count; this difference was significant for ACS visits when compared with the lowest quartile of MPR.

CONCLUSION

This study demonstrated a high level of adherence (>75%) was essential to achieve a lower incidence of common negative clinical outcomes. Further, moderate and severe hydroxyurea nonadherence may be more common than previously appreciated among children, emphasizing the importance of developing and testing innovative strategies to increase adherence.

Patient Perspectives on the Use of Digital Technology to Help Manage Cystic Fibrosis

Background

Digital health technologies (DHTs) have shown potential to improve health outcomes through improved medication adherence in different disease states. Cystic fibrosis (CF) requires care coordination across pharmacies, patients, and providers. DHTs can potentially support patients, providers, and pharmacists in diseases like CF, where high medication burden can negatively impact patient quality of life and outcomes.

Methods

In this prospective cohort study, a CF-specific mobile application (Phlo) was distributed to adults with CF who received care at the University of Utah Cystic Fibrosis Center, used an iPhone, and filled prescriptions through the University of Utah Specialty Pharmacy services. Participants were asked to use Phlo for 90 days with an optional 90-day extension period. Participants completed four surveys at baseline and after 90 days. Changes in patient-reported outcomes, adherence, clinical outcomes, and healthcare resource utilization from baseline to 90 days were tracked.

Results

Phlo allowed users to track daily regimen activities, contact their care team, receive medication delivery reminders, and share progress with their healthcare team. A web-based dashboard allowed the care team to review reported performance scores from the app. Most patients (67%) said the app improved confidence in and motivation for continuing their regimen. The most important reported benefit of Phlo was having a single location to manage their whole routine.

Conclusions

Phlo is a mobile health technology designed to help patients with CF manage their treatment regimen and improve patient-provider communication.

Longitudinal Study of Therapeutic Adherence in a Cystic Fibrosis Unit: Identifying Potential Factors Associated with Medication Possession Ratio

Cystic fibrosis (CF) is a genetic and multisystemic disease that requires a high therapeutic demand for its control. The aim of this study was to assess therapeutic adherence (TA) to different treatments to study possible clinical consequences and clinical factors influencing adherence. This is an ambispective observational study of 57 patients aged over 18 years with a diagnosis of CF. The assessment of TA was calculated using the Medication Possession Ratio (MPR) index. These data were related to exacerbations and the rate of decline in FEV1 percentage. Compliance was good for all CFTR modulators, azithromycin, aztreonam, and tobramycin in solution for inhalation. The patients with the best compliance were older; they had exacerbations and the greatest deterioration in lung function during this period. The three variables with the highest importance for the compliance of the generated Random Forest (RF) models were age, FEV1%, and use of Ivacaftor/Tezacaftor. This is one of the few studies to assess adherence to CFTR modulators and symptomatic treatment longitudinally. CF patient therapy is expensive, and the assessment of variables with the highest importance for a high MPR, helped by new Machine learning tools, can contribute to defining new efficient TA strategies with higher benefits.

Impact of pharmacy services on time to elexacaftor-tezacaftor-ivacaftor initiation

BACKGROUND: The approval of elexacaftor-tezacaftor-ivacaftor (ELX/TEZ/IVA) expanded highly effective cystic fibrosis transmembrane receptor modulator therapy to approximately 90% of persons aged 12 years and older with cystic fibrosis. Clinical pharmacists and pharmacy technicians played a key role in planning for ELX/TEZ/IVA initiation prior to US Food and Drug Administration approval as well as initiating therapy after approval. OBJECTIVE: To evaluate the impact of pharmacy services on time to ELX/TEZ/IVA initiation. METHODS: A retrospective chart review evaluated 146 patients aged at least 12 years with cystic fibrosis qualifying for ELX/TEZ/IVA at a single health system between October 21, 2019, and April 1, 2020. RESULTS: Patients filling ELX/TEZ/IVA at an integrated health system specialty pharmacy (HSSP) vs an outside specialty pharmacy (SP) started on therapy an average of 10.8 days sooner (10.8 days ± 14.0 vs 21.6 days ± 18.8, respectively; P = 0.006). More patients filling at an HSSP received ELX/TEZ/IVA within 14 days of the prescription being written compared with outside SPs (82.0% vs 41.4%, respectively; P = 0.001). Before ELX/TEZ/IVA initiation, patients were hospitalized for a cystic fibrosis-related complication for an average of 6.26 days (range = 0-183) compared with 1.16 days (range = 0-91) after ELX/TEZ/IVA initiation. Lastly, an estimated $134,810 was saved in hospitalization dollars in the 105 patients that were able to fill ELX/TEZ/IVA at an HSSP by initiating the drug an average of 10.8 days sooner than outside SPs. CONCLUSIONS: The results of this study demonstrate the value of an integrated HSSP model. The ability to fill specialty medications at an integrated HSSP may optimize medication access, control costs, and improve patient outcomes for patients receiving care within a health system.

A medication adherence-enhancing simulation intervention in pediatric cystic fibrosis

Adherence to chronic pulmonary drugs in cystic fibrosis (CF) is suboptimal. We studied the feasibility and effectiveness of a multistep medication adherence-enhancing simulation intervention for pediatric CF, which was embedded in motivational interviewing and education. Product simulation experiments were performed by the children themselves, and they addressed adherence to mucolytics/hydrators and antibiotics. Dornase alfa-treated patients aged 7-13 years were included. We invited each patient and their parents to attend an interview. PowerPoint slides were presented and discussed. The final slide invited the patient to perform the simulation experiments, and, in so doing, they experienced what happens when they either do or do not take their medication. An educational film was applied as a summary tool. A patient-centered empathic counseling style was used. Two months later, the child and their parents each completed a different anonymous questionnaire. Overall, 21 patients were included. Parents rated the means of communication and improvement in their child's motivation as very satisfactory. Children highly appreciated the experiments they performed. They often answered two questions on dornase alfa correctly and associated knowledge with adherence. Our results suggest that experiential simulation-based learning is extremely appropriate, and that this multistep intervention is feasible and effective in pediatric CF.

Using A Work System Framework to Investigate Pharmacists' Roles in Cystic Fibrosis Management

OBJECTIVE

Cystic fibrosis (CF) is a genetic disease that requires complex, lifelong treatment regimens to maintain health and reduce disease progression. The aims of this study were 1) to gain the perspectives of multiple health professions to understand medication and well-being challenges of people living with CF; and 2) to apply the Systems Engineering Initiative for Patient Safety (SEIPS) model to further identify opportunities for pharmacists to support people with CF.

METHODS

Health care professionals were recruited from a Cystic Fibrosis Center in the Midwest, to participate in audio-recorded semistructured interviews. Topics examined during the interviews included medication education for patients as well as experiences with outpatient, specialty, and community pharmacists. The themes assessed during the pharmacist interviews included support for people living with CF, preferences in conducting medication education, and pharmacist-specific counseling. Interview transcripts were thematically analyzed into categories to determine major themes. Prevalent codes were categorized into 5 major themes guided by the SEIPS model. Interrater reliability was strong (kappa = 0.94).

RESULTS

Five major themes were identified: 1) patient tasks; 2) external environment; 3) organizational conditions; 4) patient medication education; and 5) pharmacists' roles and tasks. Professionals identified the importance of the pharmacist on the multidisciplinary CF care team to enhance patient-centered care for people living with CF.

CONCLUSIONS

This study highlights health care professionals' views on the unique skillset that pharmacists add to the care team, including a reduction in medication errors, improved adherence, and overall enhanced patient care.

The indispensable role of pharmacy services and medication therapy management in cystic fibrosis

Care for people with cystic fibrosis (PWCF) is highly complex and requires a multidisciplinary approach where the pharmacist plays a vital role. The purpose of this manuscript is to serve as a guideline for pharmacists and pharmacy technicians who provide care for PWCF by providing background and current recommendations for the use of cystic fibrosis (CF)-specific medications in both the acute and ambulatory care settings. The article explores current literature surrounding the role of pharmacists and pharmacy technicians, proven pharmacy models to emulate, and pharmacokinetic idiosyncrasies unique to the CF population while also identifying areas of future research. Clinical recommendations for the use of CF-specific medications are broken down by organ system including mechanism of action, adverse events, dosages, and monitoring parameters. The article also includes quick reference tables essential to the acute and chronic medication therapy management of PWCF.

Impact of a pharmacy technician and pharmacist on time to inhaled tobramycin therapy in a pediatric cystic fibrosis clinic

BACKGROUND

Cystic fibrosis (CF) patients who grow Pseudomonas aeruginosa on respiratory culture are commonly prescribed inhaled tobramycin (TIS) to eradicate the organism. The objective of this study was to determine the impact of a pharmacy technician/pharmacist team, in conjunction with an integrated health-system specialty pharmacy (IHSSP), on the time from positive culture to prescribing and access to TIS in a pediatric CF clinic.

METHODS

A retrospective study of CF patients positive for P. aeruginosa who were prescribed TIS for eradication.

RESULTS

The study included 20 patients in the pregroup and 42 patients in the postgroup. Total median (interquartile range) days from positive culture to TIS being shipped to the patient from the pharmacy was significantly different: 15 (10.25-21) days in the pregroup and 9 (7-14) days in the post groups (p = .005). The time from positive culture to TIS prescribing was significantly different: 6 (5-12.75) days in the pregroup and 5 (3.75-6) days in the postgroup (p = .01). In the postgroup median time from prescription to the patient receiving the TIS was significantly different between the two groups 2 (2-5) days IHSSP group versus 6 (3-9) external specialty pharmacy group (p = .003). Time from prescription to prior authorization approval was the same in both groups.

CONCLUSIONS

The addition of the pharmacy team reduced time from culture to TIS being received by the patient. Patients able to fill at the IHSSP received their medication sooner than an external specialty pharmacy. The study shows the benefit of an integrated pharmacy model in conjunction with an IHSSP.

Understanding the expanding role of pharmacy services in outpatient cystic fibrosis care

Cystic fibrosis (CF) patients utilize an average of 10 (±5) medications per day. Given the complexity of the medication regimen, the CF Foundation (CFF) recommends pharmacists as members of the CF care team. The areas of pharmacy services have been identified in the literature. "Limited access pharmacists" are consulted to answer questions, assist in evaluating serum drug concentrations, provide medication education, and monitor for drug-drug interactions. Reduction in hospital length of stay has been shown through this collaboration. "Full access pharmacists" provide comprehensive medication therapy management resulting in medication adherence and access improvements, sustainability of treatments, improved provider communication, reduced medication errors and costs, expedited medication refill authorization, increased utilization of respiratory therapists, enhanced discussion of medications with CF team members, and reduction in the number of pharmacies utilized by patients to fill CF medications. An integrated CF pharmacy team are essential members of the multidisciplinary CF care team that have been shown to improve in CF medication access, increases in body weight and body mass index, reduction in prior authorization submission times, reduction in medication delivery times, expedited medication refill authorizations, increased collaboration with respiratory therapists, augmented discussion of medication with CF team members, and reduction in the number of pharmacies utilized by CF patients. There is a need to further evaluate the impact of outpatient CF pharmacy services due to the improvements in the care on patients and families affected by CF, and as the number of CFF-accredited care centers integrates CF pharmacy teams throughout the country increases.

Virtual medication tours with a pharmacist as part of a cystic fibrosis telehealth visit

Background

As a result of the coronavirus disease 2019 (COVID-19) pandemic, institutions needed innovative solutions to provide care. With implementation of telehealth, a cystic fibrosis (CF) pharmacist was able to incorporate a virtual medication tour during appointments.

Objective

The purpose of our study was to describe the uptake and impact of pharmacist-led virtual medication tours during telehealth visits in the CF clinic setting.

Practice description

Before the COVID-19 pandemic, a CF pharmacist participated in in-person multidisciplinary team visits to complete medication history reconciliation, assess adherence, assess efficacy and address possible adverse effects of medications, and work collaboratively with the CF care team and patient to create therapeutic plans. The virtual medication tour described in this study was completed in addition or as a complement to these pre-existing pharmacist roles and responsibilities.

Practice innovation

Patients seen via telehealth visit were asked to provide a virtual tour of their medications. A pharmacist completed medication history and evaluated whether storage conditions were appropriate in regard to temperature, humidity, light exposure, and accessibility to children.

Evaluation methods

A pharmacist recorded findings from the virtual medication tours and made interventions when appropriate. Descriptive statistics were used for analysis.

Results

Of 20 patients seen via telehealth for a quarterly visit during the first 3 months after implementation, 13 were willing to participate in a virtual medication tour. Before the visit, 25% had information missing from their medication list. Virtual medication tour allowed for resolution of this information 80% of the time. Three of the 4 participating patients with a child under 12 years old had medications stored in a location accessible to children.

Conclusion

A virtual medication tour led by a pharmacist can be successfully incorporated into telehealth visits and was accepted by a majority of patients. Most patients stored medications appropriately but might benefit from education on poison prevention practices.

Characterizing medication management and the role of pharmacists in caring for people living with cystic fibrosis: A work system approach

BACKGROUND

Cystic fibrosis (CF) is an autosomal recessive genetic disease requiring complex, lifelong medication regimens. Given the importance of medication in CF treatment, pharmacists are vital CF care team members in the care of people living with CF (PwCF).

OBJECTIVES

This study aimed to (1) define patients' CF medication experiences and educational needs and (2) investigate the CF outpatient clinic and community pharmacist's role in addressing patient challenges.

METHODS

A work system approach informed by the Systems Engineering Initiative for Patient Safety (SEIPS) model was used to characterize knowledge and perception of CF medication regimens, educational modalities, and pharmacist interactions for PwCF. Semistructured interviews were conducted with adults living with CF at a CF center clinic. Data analyses identified relationships between the themes in the data and 4 SEIPS work system domains: tasks, tools and technology, person, and environment.

RESULTS

Thirty PwCF interviews highlighted 4 themes regarding health care experiences: (1) medication use experience, (2) medication education needs, (3) disease experience, and (4) pharmacist and pharmacy interactions. Patients reported complex medication regimens leading to challenges with medication adherence, although the benefit of treatment was recognized. Although a high level of disease-state knowledge was identified among the participants, PwCF desired to learn about CF medication benefits and adverse effects through credible sources using multiple modalities. Many reported a benefit of pharmacist involvement in their care.

CONCLUSION

Pharmacists are well-positioned to support PwCF in adherence, medication regimen management, and medication education. Opportunities exist for growth in these supportive roles of a pharmacist in both community and outpatient clinic settings.

Impact of pharmacy technicians as part of an integrated health-system pharmacy team on improvement of medication access in the care of cystic fibrosis patients

BACKGROUND

Cystic fibrosis (CF) is a genetic disease requiring patients to take multiple medications per day. Multiple barriers exist affecting access and adherence. Studies have demonstrated the positive outcomes of pharmacist involvement in CF care. The purpose of this study is to characterize the impact of pharmacy technicians on medication access in the care of CF patients.

METHODS

A retrospective review and analysis of patient medication profiles for patients followed by the integrated pharmacy care process model was performed. Two electronic prescription pathways with pharmacy technician involvement were analyzed. One pathway using a specialty pharmacy CF pharmacy technician (SP technician) examined CF specialty medication delivery times. The other pathway examined the impact of the clinic-based CF pharmacy technician (CB technician) on the number of filling pharmacies for patients.

RESULTS

One-hundred and fifty-three patients met inclusion criteria in the CF specialty medication delivery analysis, and 56 patients met inclusion criteria filling pharmacy analysis. The median delivery time for dornase alfa decreased from 8 days to 3 days, p < .00001. The number of patients utilizing one filling pharmacy increased from 8 (14%) to 21 (38%) (p = .005); and utilizing three filling pharmacies decreased from 14 (25%) to 1 (2%) (p = .003).

CONCLUSION

The study demonstrated that pharmacy technicians as part of an integrated health-system pharmacy care process model improve medication access in the care of CF patients.

Impact of pharmacy services on cystic fibrosis transmembrane conductance regulator modulator prescribing at a pediatric cystic fibrosis center

BACKGROUND

This study was undertaken to determine if the presence of a clinical pharmacy team impacted patients' access to cystic fibrosis transmembrane conductance regulator (CFTR) modulators.

METHODS

A retrospective chart review of electronic medical records from the University of Iowa Hospitals and Clinics (UIHC) was conducted. Data were collected regarding the timing of prior authorization (PA) submissions and approvals from 2012 to 2018. The Wilcoxon rank-sum test was used to compare the meantime (days) between prescription and PA submission dates, and PA submission and approval date for all patients included in the analysis. Comparisons were made for pre- and postpharmacy services eras as well as the UIHC Specialty Pharmacy versus a non-UIHC Specialty Pharmacy.

RESULTS

Sixty-three patients were included in the final analysis. The average time between prescription date and PA submission was 12.5 days (standard deviation [SD] = 17.4 days) in the preclinical pharmacy services era and 3.5 days (SD = 5.8 days; P = .028) in the postclinical pharmacy services era. The average time to PA submission significantly decreased from 9.8 days (SD = 13.1 days) to 1.3 days (SD = 4.2 days; P < .0001) when prescriptions were filled by the UIHC Specialty Pharmacy vs a non-UIHC Specialty Pharmacy.

CONCLUSIONS

There was a significant benefit to CFTR modulator prescribing when clinical pharmacy services were incorporated in our cystic fibrosis (CF) care team, which will become increasingly important with the anticipation of new CF medications in the near future.

Patients and families experience with pharmacist care at cystic fibrosis foundation accredited clinics

Cystic fibrosis (CF) is a complex genetic, multiorgan disease. The CF Foundation (CFF) recommends a multidisciplinary team (physician, nurse, respiratory therapist, dietitian, physical therapist, social worker, mental health coordinator, clinic coordinator, and pharmacist) to work with patients and families. The objective of our study was to describe the impact of a pharmacist involved in the care of patients and families from their perspective. The CF Patient and Family Experience of Care (PFEC) is a voluntary, 50-question telephonic or internet-based survey designed to continuously collect information from patients and their families regarding their care experience. From August of 2017 through February of 2018, five questions were added to the internet survey to assess the impact of the pharmacist on the care experience. From the 666 respondents, 54% reported that a pharmacist was involved in their CF care. At two CF clinics designated as "full access" to a pharmacist, respondents reported a higher percentage of the CF-team discussed medications compared to those from three clinics designated as "limited access" to the pharmacist (95% vs 67%). Respondents in clinics with "full access" to a pharmacist were significantly more likely to get their medications refilled on time (78% vs 63%) and reported using fewer pharmacies to fill their medications. Pharmacist involvement in CF care may improve patient's access to medication and the ability to sustain use.

Cystic fibrosis-related diabetes: optimizing care with a multidisciplinary approach

Cystic fibrosis-related diabetes (CFRD) is a common complication of cystic fibrosis and can be present in over 50% of adults with the disease. CFRD is associated with poorer clinical outcomes, including accelerated pulmonary function decline and excess morbidity. The management of CFRD is complex and differs from that of type 1 and type 2 diabetes mellitus such that clinicians responsible for the care of people with CFRD must work closely with colleagues across a number of different specialities and disciplines. This review aims to discuss why a multi-disciplinary approach is important and how it can be harnessed to optimize the care of people with CFRD.

In this article, we highlight cystic fibrosis (CF) reports published in Pediatric Pulmonology during 2017. We also include articles from a variety of journals that are related or are of special interest to clinicians.

Outcome evaluation of a pharmacy-based therapy management program for patients with cystic fibrosis

OBJECTIVE

To compare medication adherence, pulmonary exacerbations, healthcare utilization, and costs for patients with cystic fibrosis (CF) who utilized a pharmacy-based therapy management program to a matched control group. We hypothesized that patient management services would be associated with better medication adherence, and thus require fewer visits to the emergency room or hospitalizations.

METHODS

This retrospective, observational cohort study used claims data from the MORE² claims Registry®. The sample consisted of CF patients, aged 6+, who had ≥1 pharmacy claim for inhaled tobramycin, inhaled aztreonam, ivacaftor, or dornase alfa from 6/2/2014-5/31/2015. Adherence was measured as proportion of days covered (PDC). Propensity score matching and multivariable regression techniques were used to compare outcomes in program participants to matched controls.

RESULTS

Of the 236 intervention and 724 control patients meeting selection criteria, 202 were propensity-matched from each cohort. Relative to the control cohort, program patients had 23% higher mean PDC for tobramycin (IRR = 1.23, P = 0.01) and were twice as likely to be adherent to tobramycin (PDC ≥ 80%) than matched controls (OR = 2.14, P = 0.04). Program patients had fewer ER visits (IRR = 0.52, P < 0.01) and slightly lower ER costs (IRR = 0.66, P = 0.06) than the control patients.

CONCLUSION

A pharmacy-based therapy management program for CF patients was associated with higher adherence to inhaled tobramycin and lower ER rates. Pharmacies that provide therapy management can support effective CF care management.

The pharmacist's role in supporting people living with cystic fibrosis

OBJECTIVES

To describe the critical need for pharmacists' involvement in outpatient care for people living with cystic fibrosis (CF).

DATA SOURCES

Not applicable.

SUMMARY

CF is a pulmonary condition that affects more than 30,000 children and adults in the United States and 70,000 people worldwide. Various complex medication regimens are given to patients with CF, some depending on the type of mutation they have in their CF transmembrane conductance regulator protein. With complex medication regimens and the increased number and variety of treatments that have become available, the medication use burden intensifies for individuals living with CF and their caregivers. Young people living with CF have a particularly difficult time adhering to medications and other therapies as they begin to rely less on their caregivers and assume greater medication management responsibility for their care. Adolescents report low adherence rates from about 40% to 47% for airway clearance methods and even lower for nutritional recommendations, about 16% to 20%. In inpatient settings, pharmacists have been successful in making medication use recommendations that have improved adherence for patients with CF while in the hospital. However, limited research has explored how provision of pharmacist supportive care and patient education in outpatient settings can improve medication adherence and quality of life for people living with CF.

CONCLUSION

There is potential for provision of outpatient pharmacy clinical services to increase medication adherence and overall quality of care for patients with CF. Higher rates of medication adherence in patients with CF could in turn improve patient outcomes and reduce overall health care costs as a result of fewer rehospitalizations. Pharmacies can implement programs designed to provide comprehensive support services and medication management from pharmacists and staff that are trained in CF care.
