Exploring Transplant Medication-Taking Behaviours in Older Adult Kidney Transplant Recipients: A Qualitative Study of Semi-Structured Interviews.

BACKGROUND: Today, older adult patients routinely undergo kidney transplantation. To support graft survival, patients must take immunosuppressant medicines for the rest of their lives. The post-transplant medication regimen is complex, and barriers to medication taking are likely confounded by both functional and intrinsic changes associated with advancing age. To develop diverse and innovative approaches to support best health outcomes in this vulnerable age group, it is imperative that the degree to which patients' needs are currently being met, be identified. AIM: The aim of this study was to examine medication-taking behaviours of kidney transplant recipients transplanted at 60 years of age or older. METHODS: This qualitative study used semi-structured patient interviews to explore how kidney transplant recipients currently manage their immunosuppressant regimen and how they cope after transplantation with the complex routine. Data were themed using the principles of Grounded Theory methodology; with interviews conducted until data saturation was reached. RESULTS: Quantitative information was collected from 14 participants who ranged in age from 66 to 77 years (at time of interview), and were prescribed a median of 13 (min: 10, max: 26) medicines. The main themes that emerged from the interview were variability in health literacy toward medicines, the importance of support networks, the need to adjust health expectations, factors that were motivators for self-care, different approaches to medication management, and different approaches to medication taking. Overall, it was found that patients prioritised medication taking above all else, and gratitude to their donor was a powerful motivator to adhere. However, strategies to support medication taking were sometimes ineffective when patients' routine changed. CONCLUSIONS: Future interventions should consider approaches to foster adaptable medication taking behaviours that stand up to changes in the day-to-day routine.

Medication taking is complicated in transplant recipients, due to the number of medicines that need to be taken and the complex nature of the treatment regimen. Challenges in older transplant recipients may be more pronounced and varied compared with younger adults. There are multiple factors that may impact medication taking in older adults and each requires consideration, including level of dependence, living arrangements, level of mobility and manual dexterity, vision and memory, and social situation. To better identify the gaps in support, patients' current perspectives around medication taking and how they cope after transplantation must be explored. Therefore, this study aimed to identify how older adult transplant recipients currently manage their anti-rejection medicine regimen. Participants described several strategies around how they manage a complex medication regimen. These included cues such as an alarm and linking the time they should take their medication to already established habits such as eating meals. Most participants discussed at length their relationships, and it seems that these relationships are often crucial to post-transplant positivity. Additionally, extreme gratitude to the donor, relative improvement in their life quality (compared with the rapid deterioration in their health when on dialysis), and fear of consequences (particularly graft failure) were important facilitators of self-care and served as timely reminders to prioritise one's own health. To foster more robust medication-taking habits, future education needs to be tailored to each individual patient and include details about how to link medication taking to already established routines (coined 'habit stacking').

Effectiveness of patient-oriented education and medication management intervention in people with decompensated cirrhosis.

People with chronic disease often have poor comprehension of their disease and medications, which can negatively affect health outcomes. In a randomised-controlled trial, we found that patients with decompensated cirrhosis who received a pharmacist-led, patient-oriented education and medication management intervention (n = 57) had greater knowledge of cirrhosis and key self-care tasks compared with usual care (n = 59). Intervention patients also experienced improved quality of life. Dedicated resources are needed to support implementation of evidence-based measures at local centres to improve outcomes.

Characterizing the pharmacokinetics and pharmacodynamics of immunosuppressant medicines and patient outcomes in elderly renal transplant patients.

This review examines what is currently known about the pharmacokinetics and pharmacodynamics of commonly prescribed immunosuppressant medicines, tacrolimus, cyclosporine, mycophenolate and prednisolone, in elderly renal transplant recipients, and reported patient outcomes in this cohort. Renal transplantation is increasing rapidly in the elderly, however, currently, long-term patient outcomes are relatively poor compared to younger adults. Some studies have suggested that elderly recipients may have higher dose-adjusted exposure and/or lower clearance of the calcineurin inhibitors tacrolimus and cyclosporine; with one study reporting up to 50% reduction in tacrolimus exposure in the elderly. Elderly transplant recipients do not appear to have higher dosage-adjusted exposure to mycophenolic acid (MPA). The effects of ageing on the pharmacokinetics of prednisolone are unknown. Only one study has examined how aging effects drug target enzymes, reporting no difference in baseline inosine 5'-monophosphate dehydrogenase (IMPDH) activity and MPA-induced IMPDH activity in elderly compared to younger adult renal transplant recipients. In elderly transplant recipients, immunosenescence likely lowers the risk of acute rejection, but increases the risk of drug-related adverse effects. Currently, the three main causes of death in elderly renal transplant recipients are cardiovascular disease, infection and malignancy. One study has showed that renal transplant recipients aged over 65 years are seven times more likely to die with a functioning graft compared with young adults (aged 18-29 years). This suggests that an optimal balance between immunosuppressant medicine efficacy and toxicity is not achieved in elderly recipients, and further studies are needed to foster long-term graft and patient survival. Lower maintenance immunosuppressant targets in elderly recipients may decrease patient susceptibility to drug side effects, however, further studies are required and appropriate targets need to be established.

Medication-Related Problems in Outpatients With Decompensated Cirrhosis: Opportunities for Harm Prevention.

People with decompensated cirrhosis are often prescribed a complex regimen of therapeutic and prophylactic medications. In other chronic diseases, polypharmacy increases the risk of medication misadventure and medication-related problems (MRPs), with associated increased morbidity, mortality, and health care costs. This study examined MRPs in a cohort of ambulatory patients with a history of decompensated cirrhosis who were enrolled in a randomized controlled trial of a pharmacist-led, patient-oriented medication education intervention and assessed the association between MRPs and patient outcomes. A total of 375 MRPs were identified among 57 intervention patients (median, 6.0; interquartile range, 3.5-8.0 per patient; maximum 17). Nonadherence (31.5%) and indication issues (29.1%) were the most prevalent MRP types. The risk of potential harm associated with MRPs was low in 18.9% of instances, medium in 33.1%, and high in 48.0%, as categorized by a clinician panel using a risk matrix tool. Patients had a greater incidence rate of high-risk MRPs if they had a higher Child-Pugh score (incidence rate ratio [IRR], 1.31; 95% confidence interval [CI], 1.09-1.56); greater comorbidity burden (IRR, 1.15; 95% CI, 1.02-1.29); and were taking more medications (IRR, 1.12; 95% CI, 1.04-1.22). A total of 221 MRPs (58.9%) were resolved following pharmacist intervention. A greater proportion of high-risk MRPs were resolved compared to those of low and medium risk (68.9% versus 49.7%; P < 0.001). During the 12-month follow-up period, intervention patients had a lower incidence rate of unplanned admissions compared to usual care (IRR, 0.52; 95% CI, 0.30-0.92). Conclusion: High-risk MRPs are prevalent among adults with decompensated cirrhosis. Pharmacist intervention facilitated identification and resolution of high-risk MRPs and was associated with reduced incidence rate of unplanned hospital admissions in this group.

Use of a patient-centred educational exchange (PCEE) to improve patient's self-management of medicines after a stroke: a randomised controlled trial study protocol.

INTRODUCTION: National and international guidelines make recommendations for secondary prevention of stroke including the use of medications. A strategy which engages patients in a conversation to personalise evidence-based educational material (patient-centred educational exchange; PCEE) may empower patients to better manage their medications. METHODS AND ANALYSIS: This protocol outlines a non-blinded randomised controlled trial. Consenting patients admitted with a diagnosis of stroke or transient ischaemic attack will be randomised 1:1 to receive either a PCEE composed of two sessions, one at the bedside before discharge and one by telephone at least 10 days after discharge from hospital in addition to usual care (intervention) or usual care alone (control). The primary aim of this study is to determine whether a PCEE improves adherence to antithrombotic, antihypertensive and lipid-lowering medications prescribed for secondary prevention of stroke over the 3 months after discharge, measured using prescription-refill data. Secondary aims include investigation of the impact of the PCEE on adherence over 12 months using prescription-refill data, self-reported medication taking behaviour, self-reported clinical outcomes (blood pressure, cholesterol, adverse medication events and readmission), quality of life, the cost utility of the intervention and changes in beliefs towards medicines and illness. ETHICS AND DISSEMINATION: Communication of the trial results will provide evidence to aid clinicians in conversations with patients about medication taking behaviour related to stroke prevention. The targeted audiences will be health practitioners and consumers interested in medication taking behaviour in chronic diseases and in particular those interested in secondary prevention of stroke.The trial has ethics approval from Metro South Human Research Ethics Committee (HREC/15/QPAH/531) and The University of Queensland Institutional Human Research Ethics (2015001612). TRIAL REGISTRATION NUMBER: ACTRN12615000888561; Pre-results.

Medication beliefs predict medication adherence in ambulatory patients with decompensated cirrhosis.

AIM: To investigate the impact of medication beliefs, illness perceptions and quality of life on medication adherence in people with decompensated cirrhosis. METHODS: One hundred adults with decompensated cirrhosis completed a structured questionnaire when they attended for routine outpatient hepatology review. Measures of self-reported medication adherence (Morisky Medication Adherence Scale), beliefs surrounding medications (Beliefs about Medicines Questionnaire), perceptions of illness and medicines (Brief Illness Perception Questionnaire), and quality of life (Chronic Liver Disease Questionnaire) were examined. Clinical data were obtained via patient history and review of medical records. Least absolute shrinkage and selection operator and stepwise backwards regression techniques were used to construct the multivariable logistic regression model. Statistical significance was set at alpha = 0.05. RESULTS: Medication adherence was "High" in 42% of participants, "Medium" in 37%, and "Low" in 21%. Compared to patients with "High" adherence, those with "Medium" or "Low" adherence were more likely to report difficulty affording their medications (P < 0.001), lower perception of treatment helpfulness (P = 0.003) and stronger medication concerns relative to medication necessity beliefs (P = 0.003). People with "Low" adherence also experienced greater symptom burden and poorer quality of life, including more frequent abdominal pain (P = 0.023), shortness of breath (P = 0.030), and emotional disturbances (P = 0.050). Multivariable analysis identified having stronger medication concerns relative to necessity beliefs (Necessity-Concerns Differential ≤ 5, OR = 3.66, 95%CI: 1.18-11.40) and more frequent shortness of breath (shortness of breath score ≤ 3, OR = 3.87, 95%CI: 1.22-12.25) as independent predictors of "Low"adherence. CONCLUSION: The association between "Low" adherence and patients having strong concerns or doubting the necessity or helpfulness of their medications should be explored further given the clinical relevance.

Optimising care of patients with chronic disease: patient-oriented education may improve disease knowledge and self-management.

Many patients with chronic disease do not possess the knowledge and skills required to access and interpret appropriate health information. A pilot study in people with liver cirrhosis (n = 50) identified that only 54% of patients could recall being given written information by a clinician and 64% had self-sought information, most commonly using the Internet. Many patients reported difficulties understanding the material and the majority wanted more accessible information. A pilot chronic disease educational booklet was well received by the study participants with 85% reporting it was helpful and 78% using it in between clinic appointments.

Patient-oriented education and medication management intervention for people with decompensated cirrhosis: study protocol for a randomized controlled trial.

BACKGROUND: People with decompensated cirrhosis require complex medical care and are often prescribed an intricate and frequently changing medication and lifestyle regimen. However, many patients mismanage their medications or have poor comprehension of their disease and self-management tasks. This can lead to harm, hospitalization, and death. METHODS/DESIGN: A patient-oriented education and medication management intervention has been developed for implementation at a tertiary hospital hepatology outpatient center in Queensland, Australia. Consenting patients with decompensated cirrhosis will be randomly allocated to education intervention or usual care treatment arms when they attend routine follow-up appointments. In the usual care arm, participants will be reviewed by their hepatologist according to the current model of care in the hepatology clinic. In the intervention arm, participants will be reviewed by a clinical pharmacist to receive the education and medication management intervention at baseline in addition to review by their hepatologist. Intervention participants will also receive three further educational contacts from the clinical pharmacist within the following 6-month period, in addition to routine hepatologist review that is scheduled within this time frame. All participants will be surveyed at baseline and follow-up (approximately 6 months post-enrollment). Validated questionnaire tools will be used to determine participant adherence, medication beliefs, illness perceptions, and quality of life. Patients' knowledge of dietary and lifestyle modifications, their current medications, and other clinical data will be obtained from the survey, patient interview, and medical records. Patient outcome data will be collected at 52 weeks. DISCUSSION: The intervention described within this protocol is ready to adapt and implement in hepatology ambulatory care centers globally. Investigation of potentially modifiable variables that may impact medication management, in addition to the effect of a clinical pharmacist-driven education and medication management intervention on modifying these variables, will provide valuable information for future management of these patients.

Prevalence of medication discrepancies in patients with cirrhosis: a pilot study.

BACKGROUND: Cirrhosis patients are prescribed multiple medications for their liver disease and comorbidities. Discrepancies between medicines consumed by patients and those documented in the medical record may contribute to patient harm and impair disease management. The aim of the present study was to assess the magnitude and types of discrepancies among patient-reported and medical record-documented medications in patients with cirrhosis, and examine factors associated with such discrepancies. METHODS: Fifty patients who attended a hospital hepatology outpatient clinic were interviewed using a questionnaire composed of mixed short-response and multiple-choice questions. Patients' reported medication use was compared with documentation in the hospital medical records and pharmacy database. Medication adherence was assessed using the 8-question ©Morisky Medication Adherence Scale (MMAS-8). The multivariate logistic regression model was constructed using clinically relevant and/or statistically significant variables as determined by univariate analysis. All p-values were 2-sided (α = 0.05). RESULTS: Twenty-seven patients (54.0 %) had ≥1 discrepancy between reported and documented medicines. Patients with ≥1 discrepancy were older (p = 0.04) and multivariate analysis identified taking ≥5 conventional medicines or having a 'low' or 'medium' adherence ranking as independent predictors of discrepancy (adjusted OR 11.0 (95 % CI 1.8-67.4), 20.7 (95 % CI 1.3-337.7) and 49.0 (95 % CI 3.3-718.5) respectively). Concordance was highest for liver disease medicines (71.9 %) and lowest for complementary and alternative medicines (14.5 %) and respiratory medicines (0 %). CONCLUSION: There is significant discrepancy between sources of patient medication information within the hepatology clinic. Medication reconciliation and medicines-management intervention may address the complex relationship between medication discrepancies, number of medications and patient adherence identified in this study.

Impact of community pharmacist intervention discussing patients' beliefs to improve medication adherence.

BACKGROUND: Adherence to evidence based medicines in patients who have experienced a myocardial infarction remains low. Individual's beliefs towards their medicines are a strong predictor of adherence and may influence other factors that impact on adherence. OBJECTIVE: To investigate if community pharmacists discussing patients' beliefs about their medicines improved medication adherence at 12 months post myocardial infarction. SETTING: This study included 200 patients discharged from a public teaching hospital in Queensland, Australia, following a myocardial infarction. Patients were randomised into intervention (n = 100) and control groups (n = 100) and followed for 12 months. METHOD: All patients were interviewed between 5 to 6 weeks, at 6 and 12 months post discharge by the researcher using the repertory grid technique. This technique was used to elicit the patient's individualised beliefs about their medicines for their myocardial infarction. In the intervention group, patients' beliefs about their medicines were communicated by the researcher to their community pharmacist. The pharmacist used this information to tailor their discussion with the patient about their medication beliefs at designated time points (3 and 6 months post discharge). The control group was provided with usual care. MAIN OUTCOME MEASURE: The difference in non-adherence measured using a medication possession ratio between the intervention and control groups at 12 months post myocardial infarction. RESULTS: There were 137 patients remaining in the study (intervention group n = 72, control group n = 65) at 12 months. In the intervention group 29 % (n = 20) of patients were non-adherent compared to 25 % (n = 16) of patients in control group. CONCLUSION: Discussing patients' beliefs about their medicines for their myocardial infarction did not improve medication adherence. Further research on patients beliefs should focus on targeting non-adherent patients whose reasons for their non-adherence is driven by their medication beliefs.

An evaluation of medication review reports across different settings.

BACKGROUND: There is a growing body of evidence which supports that a pharmacist conducted medication review increases the health outcomes for patients. A pharmacist integrated into a primary care medical centre may offer many potential advantages in conducting medication reviews in this setting however research describing this is presently limited. OBJECTIVE: To compare medication review reports conducted by pharmacists practicing externally to a medical centre to those medication review reports conducted by an integrated practice pharmacist. The secondary objective was to compare medication review reports conducted by pharmacists in the patient's home to those conducted in the medical centre. SETTING: A primary care medical centre, Brisbane, Australia. METHOD: A retrospective analysis of pharmacist conducted medication reviews prior to and after the integration of a pharmacist into a medical centre. MAIN OUTCOME MEASURES: Types of drug related problems identified by the Pharma cists, recommended intervention for drug related problems made by the pharmacist, and the extent of implementation of pharmacist recommendations by the general practitioner. RESULTS: The primary drug related problem reported in the practice pharmacist phase was Additional therapy required as compared to Precautions in the external pharmacist phase. The practice pharmacist most frequently recommended to add drug with Additional monitoring recommended most often in the external pharmacists. During the practice pharmacist phase 71 % of recommendations were implemented and was significantly higher than the external pharmacist phase with 53 % of recommendations implemented (p < 0.0001). Two of the 23 drug related problem domains differed significantly when comparing medication reviews conducted in the patient's home to those conducted in the medical centre.

Does a primary care practice pharmacist improve the timeliness and completion of medication management reviews?

OBJECTIVE: To describe the effect of integrating a pharmacist into the general practice team on the timeliness and completion of pharmacist-conducted medication reviews. METHOD: A pharmacist was integrated into an Australian inner-city suburb general practice medical centre to provide medication reviews for practice patients. A retrospective analysis of medication reviews with two time periods was conducted: pre-integration of the practice pharmacist and post-integration of the practice pharmacist. In an effort to obtain a measure of external validity the data were compared to data from the Division of General Practice in which the medical centre is located. KEY FINDINGS: There were 70 patients referred for medication review in the pre-integration phase and 314 patients referred in the post-integration phase. The time to complete the medication review process was significantly reduced from a median of 56 days to 20 days with a practice pharmacist. Prior to having a practice pharmacist 52% of patients did not have the service billed by the general practitioner, which was reduced to 6% during the post-integration phase. CONCLUSION: The results from this trial show that the integration of a pharmacist into the general practice team was associated with an increase in the timeliness and completion rate of medication reviews.

Integrating a pharmacist into the general practice environment: opinions of pharmacist's, general practitioner's, health care consumer's, and practice manager's.

BACKGROUND: Pharmacists are viewed as highly trained yet underutilised and there is growing support to extend the role of the pharmacist within the primary health care sector. The integration of a pharmacist into a general practice medical centre is not a new concept however is a novel approach in Australia and evidence supporting this role is currently limited. This study aimed to describe the opinions of local stakeholders in South-East Queensland on the integration of a pharmacist into the Australian general practice environment. METHODS: A sample of general practitioners, health care consumers, pharmacists and practice managers in South-East Queensland were invited to participate in focus groups or semi-structured interviews. Seeding questions common to all sessions were used to facilitate discussion. Sessions were audio recorded and transcribed verbatim. Leximancer software was used to qualitatively analyse responses. RESULTS: A total of 58 participants took part in five focus groups and eighteen semi-structured interviews. Concepts relating to six themes based on the seeding questions were identified. These included positively viewed roles such as medication reviews and prescribing, negatively viewed roles such as dispensing and diagnosing, barriers to pharmacist integration such as medical culture and remuneration, facilitators to pharmacist integration such as remuneration and training, benefits of integration such as access to the patient's medical file, and potential funding models. CONCLUSIONS: These findings and future research may aid the development of a new model of integrated primary health care services involving pharmacist practitioners.

Exploring the beliefs of heart failure patients towards their heart failure medicines and self care activities.

AIM: To identify Heart Failure patients' beliefs towards their medications and how these beliefs relate to adherence. METHOD: Patients attending a multi-disciplinary, community based heart failure clinic on the Gold Coast, Australia were interviewed using a questionnaire composed of fours parts: repertory grid technique; Beliefs About Medicines Questionnaire (BMQ); Medicines Adherence Reporting Scale (MARS); demographic details. Patients were divided into those categorised as adherent (MARS score ≥ 23) and those categorised as non-adherent (MARS score < 23). Necessity beliefs scores from BMQ and the frequency of statements generated from the repertory grid portion of the questionnaire were compared between these two groups. RESULTS: Forty-three patients were interviewed with a mean age (±SD) of 64 (±17) years and thirty-six (83.7 %) were male. Thirty-seven (86.0 %) patients were categorised as adherent; the remaining six (14.0 %) as non-adherent. The 43 patients generated a total of 262 statements about their medicines. The three most common themes identified were Related to fluid (36.6 %), Helps the heart (31.7 %) and Related to weight (13.7 %). There was a significantly higher median necessity score in the adherent group compared to the non adherent group (22.0 vs. 19.5, p = 0.0272). Patients with a strong necessity score also had significantly higher self reported adherence compared to patients with a strong concerns score (21.5 vs. 18.0, p = 0.006). CONCLUSION: This study suggests that patients with heart failure possessing a strong belief in the necessity of their treatment regimen are more likely to demonstrate better adherence.

BODE score is a useful predictor of hospital admission in rural patients with chronic obstructive pulmonary disease.

BACKGROUND AND OBJECTIVE: COPD is a chronic illness with frequent episodic exacerbations that require admission to hospital. The aim of this study was to identify risk factors (or predictors) for hospital admission in a sample of rural COPD patients. METHODS: COPD patients from the Goulburn and Crookwell areas of New South Wales, Australia, were included in the study. Patients were divided into two groups: those with two or fewer admissions, and those with three or more admissions in the last year. Patient interviews were conducted, and data were collected on demographics, consumption of health resources, COPD severity measures (BODE score) and quality of life. RESULTS: There were 32 patients recruited with a median age of 68 years, and 21 (65.6%) were male. There were no significant differences in risk factors (or predictors) identified between the two groups. A statistical difference was found between the two groups, with patients with three or more hospital admissions having a higher BODE score (P = 0.004), poorer quality-of-life score (P = 0.015) and reduced exercise tolerance (P = 0.001). CONCLUSIONS: In this small sample of COPD patients, there were no clear differences in terms of risk factors for COPD admission between the two groups. The BODE score was found to be a useful predictor of disease severity and likelihood of hospital admission.

Ascertaining consumer perspectives of medication information sources using a modified repertory grid technique.

OBJECTIVE: To establish the range of medicine information sources used by consumers and their perception of the reliability of these, using the repertory grid technique. METHOD: Consumers visiting three community pharmacies in Brisbane, Australia, were interviewed using the repertory grid technique. During the interview, consumers were asked to name up to three medicine information sources that they used for a supermarket medicine, an over-the-counter medicine and a prescription medicine. They were then presented with their named information sources in groups of three and asked to discriminate between these in terms of their perceived reliability of the information source. The descriptors used by the consumer to discriminate between the information sources are known as constructs and these were recorded. The consumer was then asked to rate each of their information sources against each generated construct. MAIN OUTCOME MEASURE: The range of information sources generated was determined along with the perceived reliability of these from the calculated median score of each information source when rated on each generated construct. RESULTS: A total of 110 consumers were interviewed and identified 648 information sources that they would use. The most frequent information sources cited by the 110 consumers were their doctor (83%), written information (90%) and the pharmacist (78%). There were a total of 299 constructs generated by 88 of the consumers and these were themed into 16 discrete categories. The most common generated constructs themes were "good knowledge" (15%), "training" (14%) and "trustworthiness" (13%). The consumer perception of their information sources were that the doctor and pharmacist have good knowledge (median score 1) and are trained (median score 1) and were perceived to be trustworthy (median score 3 and 2, respectively). CONCLUSION: The repertory grid technique was successful in identifying the information sources consumers accessed to find out about their medicines and in identifying the perception of these sources in terms of their reliability. The repertory grid technique offers a novel method for future research into consumer preferences for different treatment options.
