Medication adherence to inflammatory bowel disease medications in Aotearoa New Zealand and correlation with health outcomes: A nationwide database analysis.

AIMS: Inflammatory bowel disease (IBD) management entails long-term medication therapy. Worse disease outcomes and reduced quality of life might arise from poor medication adherence (MA). This study is the first to investigate patients with IBD's adherence across Aotearoa New Zealand and its relationship with disease outcomes. METHODS: Dispensing claims data (Pharmaceutical Collection) were used to calculate (3- and 5-year) adherence, using daily polypharmacy possession ratio. Using hospitalization data (National Minimum Dataset), the relationship between adherence and the numbers of hospitalizations and corticosteroid dispensings was investigated. RESULTS: In total, 4654 patients (53% female; 55% Crohn's disease [CD], 45% ulcerative colitis [UC]; median age-at-first-dispensing, 43 years) and 3148 patients (54% female; 55% CD, 44% UC; median age-at-first-dispensing, 44 years) were in the 3- and 5-year cohorts, respectively. The 3- and 5-year cohorts had mean 4.6 and 4.2 IBD-related hospitalizations and 6.9 and 9.2 corticosteroid dispensings, respectively. Average adherence estimates were 77.4% (95% confidence interval: 76.9-78.0%) and 74.9% (95% confidence interval: 74.1-75.6%; 3 and 5 years), while 54% and 51% of patients, respectively, had good adherence (MA ≥ 80%). There was no correlation between adherence and the numbers of hospitalizations (Pearson's R = -.0007; P = .65 and R = -.04; P = .02 [3 and 5 years]) and corticosteroid dispensings (R = .08; P = <.0001 and R = .08; P = <.0001, respectively). CONCLUSION: MA of Aotearoa New Zealand patients with IBD is moderately high but just over half of patients meet the adherent threshold. There was no correlation between adherence and hospitalizations or corticosteroid dispensings; hence, research into longitudinal adherence patterns and associated factors is needed.

Proton pump inhibitor use: systematic review of global trends and practices.

PURPOSE: Proton pump inhibitors (PPIs) reduce acid secretion in the stomach and rank as one of the most widely used acid-suppressing medicines globally. While PPIs are safe in the short-term, emerging evidence shows risks associated with long-term use. Current evidence on global PPI use is scarce. This systematic review aims to evaluate global PPI use in the general population. METHODS: Ovid MEDLINE, Embase, and International Pharmaceutical Abstracts were systematically searched from inception to 31 March 2023 to identify observational studies on oral PPI use among individuals aged ≥ 18 years. PPI use was classified by demographics and medication factors (dose, duration, and PPI types). The absolute numbers of PPI users for each subcategory were summed and expressed as a percentage. RESULTS: The search identified data from 28 million PPI users in 23 countries from 65 articles. This review indicated that nearly one-quarter of adults use a PPI. Of those using PPIs, 63% were less than 65 years. 56% of PPI users were female, and "White" ethnicities accounted for 75% of users. Nearly two-thirds of users were on high doses (≥ defined daily dose (DDD)), 25% of users continued PPIs for > 1 year, and 28% of these continued for > 3 years. CONCLUSION: Given the widespread use PPIs and increasing concern regarding long-term use, this review provides a catalyst to support more rational use, particularly with unnecessary prolonged continuation. Clinicians should review PPI prescriptions regularly and deprescribe when there is no appropriate ongoing indication or evidence of benefit to reduce health harm and treatment cost.

Disparities in utilisation of combined oral contraceptives in Aotearoa New Zealand: A cross-sectional whole-of-population study.

AIMS: The combined oral contraceptive (COC) is the most commonly used hormonal contraceptive in Aotearoa New Zealand (Aotearoa/NZ). Currently there is limited data available on who uses COC in Aotearoa/NZ. The aims were to (i) define the population of reproductive-aged females in Aotearoa/NZ in 2018 and identify the rate of COC use among this group and (ii) describe the sociodemographic and geographic characteristics of the population of COC users compared to the general population of reproductive-aged females in 2018. METHODS: This whole-of-population cross-sectional study used the Integrated Data Infrastructure, a large research database managed by Statistics New Zealand. Females aged 16-50 years with complete sociodemographic and geographic information in 2018 from Aotearoa/NZ's estimated resident population were included. COC dispensing records to this cohort were identified from the national Pharmaceutical Collection. This paper reports descriptive counts of COC use and employs generalised linear regression with a binomial distribution and a log link to estimate adjusted risk ratios (aRR) of COC use for key sociodemographic and geographic subgroups. RESULTS: Of 1 113 750 individuals in the study, 159 789 (14.3%) were dispensed as COC in 2018. European/other individuals were most likely to use COC (aRR: 2.72, 2.67-2.78), and Pacific Peoples were least likely (aRR: 0.56, 0.55-0.58) to use COC. Individuals residing in the most deprived quintile had less COC use than individuals in the least deprived quintile (aRR: 0.73, 0.72-0.74). CONCLUSION: Our study is able to highlight significant disparities in use by ethnicity, area-level deprivation, and geographic factors.

A mixed methods study on medicines information needs and challenges in New Zealand general practice.

BACKGROUND: Medicines are central to healthcare in aging populations with chronic multi-morbidity. Their safe and effective use relies on a large and constantly increasing knowledge base. Despite the current era of unprecedented access to information, there is evidence that unmet information needs remain an issue in clinical practice. Unmet medicines information needs may contribute to sub-optimal use of medicines and patient harm. Little is known about medicines information needs in the primary care setting. The aim of this study was to investigate the nature of medicines information needs in routine general practice and understand the challenges and influences on the information-seeking behaviour of general practitioners. METHODS: A mixed methods study involving 18 New Zealand general practitioner participants was undertaken. Quantitative data were collected to characterize the medicines information needs arising during 642 consultations conducted by the participants. Qualitative data regarding participant views on their medicines information needs, resources used, challenges to meeting the needs and potential solutions were collected by semi-structured interview. Integration occurred by comparison of results from each method. RESULTS: Of 642 consultations, 11% (n = 73/642) featured at least one medicines information need. The needs spanned 14 different categories with dosing the most frequent (26%) followed by side effects (15%) and drug interactions (14%). Two main themes describing the nature of general practitioners' medicines information needs were identified from the qualitative data: a 'common core' related to medicine dose, side effects and interactions and a 'perplexing periphery'. Challenges in the perplexing periphery were the variation in information needs, complexity, 'known unknowns' and 'unknown unknowns'. Key factors affecting general practitioners' strategies for meeting medicines information needs were trust in a resource, presence of the patient, how the information was presented, scarcity of time, awareness of the existence of a resource, and its accessibility. CONCLUSIONS: General practitioners face challenges in meeting wide-ranging medicines information needs in patients with increasingly complex care needs. Recognising the challenges and factors that influence resource use in practice can inform optimisation of medicines information support resources. Resources for general practitioners must take into account the complexity and time constraints of real-world practice. An individually responsive approach involving greater collaboration with pharmacists and specialist medicines information support services may provide a potential solution.

A systematic review and meta-analysis of pharmacist-led fee-for-services medication review.

AIM: The aim was to examine the impact of fee-for-service pharmacist-led medication review on patient outcomes and quantify this according to the type of review undertaken, e.g. adherence support and clinical medication review. METHODS: Relevant published studies were identified from Medline, Embase and International Pharmaceutical Abstract databases (from inception to February 2011). Study inclusion criteria were fee-for-service medication review, presence of a control group and pre-specified patient outcomes. Outcomes were grouped into primary (changes in biomarkers, hospitalization, and mortality) and secondary outcomes (medication adherence, economic implications and quality of life). Meta-analyses for primary outcomes were conducted using random effects models and secondary outcomes were summarized using descriptive statistics. RESULTS: Of the 135 relevant articles located, 21 studies met the inclusion criteria for primary outcomes and 32 for secondary outcomes. Significant results favouring pharmacists' intervention were found for blood pressure (OR 3.50, 95% CI 1.58, 7.75, P = 0.002) and low density lipoprotein (OR 2.35, 95% CI 1.17, 4.72, P = 0.02). Outcomes on hospitalization (OR 0.69, 95% CI 0.39, 1.21, P = 0.19) and mortality (OR 1.50, 95% CI 0.65 to 3.46, P = 0.34) indicated no differences between the groups. On subgroup analysis, clinical medication review (OR 0.46, 95% CI 0.26, 0.83, P = 0.01) but not adherence support review (OR 0.88, 95% CI 0.59, 1.32, P = 0.54) reduced hospitalization. CONCLUSIONS: The majority of the studies (57.9%) showed improvement in medication adherence. Fee-for-service pharmacist-led medication reviews showed positive benefits on patient outcomes. Interventions that include a clinical review had a significant impact on patient outcomes by attainment of target clinical biomarkers and reduced hospitalization.

Stress, burnout, and the need for support: a survey of early career pharmacists.

BACKGROUND: Burnout of health professionals is of concern internationally and the pharmacy profession is no exception. The period of transition from University to autonomous practitioner is recognized to be challenging and these Early Career Pharmacists (ECPs), may be at increased risk of stress and burnout. OBJECTIVES: This study aimed to collect data on the current extent of self-identified stress and burnout, of ECPs, and to (i) identify contributing factors and (ii) identify strategies used to manage this stress. METHODS: This study was conducted in Aotearoa New Zealand and was based on a survey used previously in Australia. A national database was used to identify all pharmacists who had been registered for <10 years. The survey was emailed to each pharmacist, and was further advertised through social media platforms. RESULTS: A total of 1418 ECPs were identified and invited to participate, and responses were received by 416 of these. The majority of respondents were female (73%) and community pharmacy based (79%). A vast majority (89%) indicated that a normal working day was at least moderately stressful with 79% indicating a level of burnout. These reflect a combination of "external" stressors, i.e. negative patient interactions, staff shortages, and "internal" stressors, i.e. fear of making a mistake, adjustment from University to working life. CONCLUSIONS: Stress and burnout appear to be widespread in the ECPs, this study highlights areas of concern and potential support where efforts can be focussed to create a more sustainable working environment.

Career outlook and satisfaction in the presence of workload intensification-a survey of early career pharmacists.

BACKGROUND: The demographics of the pharmacy workforce is changing with an increased proportion of pharmacists less than 30 years old (early career pharmacists-ECPs). In parallel, the profession has experienced workload intensification and workforce attrition. It is important to understand ECPs career satisfaction to retain this section of the pharmacy profession. OBJECTIVES: This study aimed to collect data on the current career satisfaction of ECPs, and identify workplace factors that were most important to this group. Further, to use these findings to inform sector recommendations. METHODS: A steering group of ECPs in Aotearoa New Zealand developed a survey based on one used previously. An invitation email was sent to all pharmacists who had been registered for less than 10 years and were members of the Pharmaceutical Society of New Zealand. RESULTS: A total of 1418 ECPs were identified and invited to participate, and responses were received by 416 of these. While 90% believe that they are making a useful contribution to the health of their patients, over half are unhappy and discontented, with over a third dissatisfied with their careers. A large proportion (44%) were considering leaving the profession in the next 5 years. The top three factors for career satisfaction were ability to progress and learn new skills, the people they work with, and the remuneration. CONCLUSIONS: This study provides a starting point for understanding the current environment and level of dissatisfaction of young pharmacists. There are several areas of concern that need to be addressed if a strong vibrant viable pharmacy profession is to be achieved.

Using electronic health records in analysing medication adherence in southern New Zealand patients with inflammatory bowel diseases.

AIMS: Electronic health records (EHRs) are widely used in medication adherence (MA) assessment. Poor adherence in patients with inflammatory bowel diseases (IBD) can lead to worse disease outcomes and increased health costs. This study explores the suitability of southern New Zealand EHRs for estimating adherence, and the relationship between adherence and corticosteroid dispensings (indicating negative disease outcomes). METHODS: Medication dispensing EHR data of former Southern District Health Board IBD patients were analysed to estimate 3-year adherence, using daily polypharmacy possession ratio. The correlation with the number of corticosteroid dispensings was investigated. RESULTS: Of 248/1,290 (19%) consenting patients, only 108/248 (44%) had sufficient data available (46%/54% Crohn's disease/ulcerative colitis; 57% female; 89.8%/0.9% NZ European/Maori; mean 5.1 corticosteroid dispensings). Mean adherence was 83.2% (95% confidence interval [CI] 80.0-86.4; standard deviation [SD]:16.7), with 69% of patients having MA ≥80% (good adherence). Median adherence was 13% higher for males versus females (96% vs 83%; p=0.0001). There was no correlation between adherence and the number of corticosteroid dispensings (Pearson's r=0.11; p>0.05). These findings should be considered with caution as the data were not obtained from all pharmacies and the quantum/nature of missing data is unknown. CONCLUSIONS: The patients' adherence seems high, with no correlation with corticosteroid dispensings demonstrated. Useful EHR data are available but need optimisation for adherence assessments.

Improving Medication Adherence Levels in Inflammatory Bowel Disease (IBD) Patients: A Narrative Evidence-Based Review.

Inflammatory bowel disease (IBD) management is typified by a long-term medication regimen which can comprise multiple medications prescribed in different combinations, doses, frequencies, and with various administration routes. This complexity can make medication adherence (MA) - patients taking their medications per the prescription - for patients with IBD a challenge. The research corpus contains diverse interventions aimed at improving MA in patients with IBD. Therefore, to condense the evidenced strategies for ease of reference, this narrative evidence-based review broadly outlines the patient-level interventions reported. The interventions are grouped as educational, behavioural, cognitive-behavioural, and multicomponent. They, however, present mixed results as to their efficacy at improving MA, with those employing combined approaches being the most promising. This reflects the reality that MA is impacted by multiple factors encompassing those pertaining to the patient, disease, therapy, patients' socioeconomic status, and health system. Hence, the most ideal interventions would likely be multifaceted patient-level interventions alongside policy/system-level strategies, to maximise the potential for successfully improving patients' MA. These findings might have been impacted by the heterogeneity of the studies in terms of the method of MA assessment, duration of interventions, and more besides.

Constraints on medication-based inflammatory bowel disease therapy in Aotearoa New Zealand-why medication adherence is important.

The therapeutic landscape for treating Inflammatory Bowel Disease (IBD) in Aotearoa New Zealand had remained largely unchanged for about a decade; however, just this year, two further biologic medications became available. In an international context, these medications are not exactly new, and several other highly efficacious, modern medications and treatment paradigms are available overseas but not in New Zealand. Medication adherence (MA), alongside factors including (relaxation of) medicines funding criteria, specialist availability, IBD awareness in primary healthcare etc., contributes to good patient care. Hence, we contend that MA remains of particular importance for New Zealand patients with IBD to derive maximum benefits from the limited therapeutic options available. Moreover, increased research and interventions for promoting MA, in IBD especially, are crucial.

"It's just like putting your socks on": patients' perspectives on inflammatory bowel disease medication adherence.

Background: A careful, often life-long, medication regimen is central to therapy for Inflammatory Bowel Disease (IBD) - a chronic gut disorder. Hence, medication adherence (MA) - patients taking medications in line with prescription - is important. Previous research indicates that a third of patients with IBD in southern New Zealand have poor medication adherence (MA). Objective: This study investigated these patients' experiences to determine factors that influence their MA, for the first time. Methods: Two focus group discussions (FGDs) were held with IBD patients in Otago, New Zealand. Reflexive thematic analysis from a 'direct realist' viewpoint was used to analyse the data. Results: Data were analysed in three segments: perceptions, experiences and support. Participants perceived MA as a "duty" that was very important to their wellbeing. The participants' MA was centred around a routine requiring proactivity to maintain. MA was negatively impacted by side effects and regimen factors including (high) pill numbers/dose frequency, and getting refills was framed as challenging; whilst healthcare professionals were presented as major MA facilitators. Lastly, the support structures identified included family, friends and colleagues as well as targeted health system factors e.g. medication subsidies. Conclusions: Factors spanning those related to the patients, their socioeconomic status, the disease, IBD therapy and the health system were presented as influencing IBD patients' MA in southern NZ. Thus, multifaceted interventions are needed across the health system to overcome the inhibiting and promote the facilitating elements.

Understanding the factors influencing prescriber uptake of pharmacist recommendations in secondary care.

BACKGROUND: Pharmacists are increasingly recognized as medication experts who can bring much to clinical teams and decision making. The inclusion of a pharmacist into a multidisciplinary team, including ward rounds, can be sporadic in some settings, meaning pharmacists are not always present at the point of decision making. In this way, subsequent recommendations may not always be adopted. Understanding the perceptions of prescribers to pharmacist input and preferences for receiving pharmacist input, may result in more effective and efficient patient care. OBJECTIVE: The purpose of this study is to understand how prescribers view pharmacist contributions and the factors that facilitate or hinder acceptance of pharmacist recommendations within a hospital setting. METHOD: This mixed methods study consisted of two stages, initially focus groups and an online survey. Thematic analysis of the focus group discussions was conducted, and these formed the basis of the survey. A total of 17 prescribers participated in the focus groups and 99 of 335 prescribers participated in the survey. The questions centred on 4 key aspects, 1) the perceived role of a pharmacist, 2) communication strategies 3) the value added by pharmacists and 4) barriers and enablers to adopting pharmacist recommendations. RESULTS: Prescribers strongly valued dosing advice and information on medication interactions. Some prescribers did not believe that a pharmacist should attend ward rounds, with more senior clinicians seeing value of recommendations being given at the time of medication initiation. Within a busy clinical setting several barriers were identified, including communication method, differing priorities, presence of pharmacist at the time of decision making, and consultant led hierarchy. CONCLUSION: Several factors influence acceptance of pharmacists' recommendations. Working on communication methods may overcome some, but others such as pharmacist presence on rounds and consultant led decision-making hierarchy may be harder to change.

Pharmacists' views and desires regarding pharmacist administration of vaccines in New Zealand.

OBJECTIVES: To explore pharmacists' views and experiences of pharmacist-administered vaccinations, motivators and barriers to pharmacists administering vaccinations and their preferences for expansions to such services. METHODS: All practising pharmacist members (n = 3400) of the Pharmaceutical Society of New Zealand were invited to participate in an online survey in 2017. KEY FINDINGS: A total of 468 pharmacists completed the survey (14%). Most (86%) strongly agreed/agreed that pharmacists should provide vaccinations, primarily citing patient benefit, for example, convenience, potential for increased vaccination uptake, easing general practice burden and better utilisation of the pharmacist. Half had completed vaccinator training, mainly for professional satisfaction, to help public or community health and/or to provide a new service for their community. Trained pharmacists had administered influenza (95%), pertussis (47%), zoster (45%) and/or meningococcal vaccines (13%), with patient cost limiting some vaccination uptake. Cost or workplace constraints were leading reasons for the 17% not planning to undertake vaccinator training. Key barriers for pharmacy owners not offering vaccinations were set-up or other costs, insufficient funding (62%) or staffing/time concerns (27%). Some trained vaccinators (39%) wanted the recipient age lowered below 13 years, and 44% wanted intern pharmacists to be able to administer vaccinations. CONCLUSION: This study found strong support for this service, including benefits for patients, and for customer relationships. Identified barriers including service setup and patient costs could be reduced by expanding the categories (e.g. pharmacy students and technicians) of staff able to vaccinate and having more government funded vaccines available through pharmacies, therefore, improving access for patients.

Adherence to Inflammatory Bowel Disease Medications in Southern New Zealand.

Background: Inflammatory bowel diseases (IBDs) require continuous clinical management; poor medication adherence may result in worse disease outcomes and increased healthcare costs. This study investigated medication adherence and associated risk factors in IBD patients. Methods: Otago (New Zealand) IBD patients were mailed questionnaires on demographics, medication-taking behavior, and a validated Probabilistic Medication Adherence Scale (ProMAS). Results: The response rate was 29.7% (n = 174/590). The study sample was mean (SD) 50.5 (16.9) years old, 57.9% female, 49.4% had Crohn's disease, and 43.9% ulcerative colitis, with median of 9.5 years (interquartile range: 5.0-22.0) of IBD duration. About 31.1% scored below medium adherence according to ProMAS. About 11.9%, 24.7%, and 23.1% reported failing to renew, purposely not taking, and stopping taking medications, respectively; 27.2% of those who reported having no issues taking medication scored below medium on the ProMAS. Older age was associated with higher ProMAS adherence score (Pearson's r = .25; P = .0014). There were no differences in medication adherence between the types of IBDs (P = .87), disease activity status (P = .70), or gender (P = .27). There was no correlation between the number of medications and level of adherence (Pearson's r = .09; P = .27). About 18.7%, 10.1%, and 5.0% of patients reported forgetting to take medications when traveling, when out of routine, and when busy, respectively. The most used strategies to remember medications included utilizing specific routines (40.1%) and keeping medications in specific locations (21.1%). Conclusions: A third of IBD patients had below medium medication adherence. There were discrepancies between self-reported and tool-assessed medication adherence scores with over one-third of patients underestimating/overestimating their adherence.

Synthetic cannabis: adverse events reported to the New Zealand Pharmacovigilance Centre.

INTRODUCTION: Synthetic Cannabinoid Receptor Agonists (SCRA) were legally available in New Zealand (NZ) prior to May 2014. During the period November 2012-November 2019, reports of adverse events associated with SCRA use from across the country were submitted to the New Zealand Pharmacovigilance Centre (NZPhvC). The purpose of this study was to investigate adverse reactions associated with SCRA reported to the NZPhvC. METHODS: The NZPhvC database was searched for adverse events involving SCRA. Cases were extracted and analysed for demographic information of users, reactions reported and SCRA involved. Summary statistics were performed using SAS 9.3. RESULTS: One hundred and thirteen cases were identified from 1 November 2012 to 31 November 2019, comprising 81 males (71.7%) and 32 females (28.3%), with a mean age of 28.4 ± 10.1 years. Ethnicity included European (51.3%, n = 58), Maori (39.8%, n = 45), Indian (1.8%, n = 2), and Polynesian (0.9%, n = 1). There were a total of 327 reactions recorded in these cases, and the majority were psychiatric (52%, n = 170), followed by nervous system (11%, n = 35), alimentary (7%, n = 24), and cardiovascular (7%, n = 23). Where the compounds could be identified, the majority of events involved AB-FUBINACA (n = 18), 5 F-PB-22 (n = 17), and PB-22 (n = 6). CONCLUSIONS: This study found that young, male and European populations frequently were involved in SCRA adverse events. A disproportionate number of Maori were present in this group. Psychiatric reactions were of clinical significance, and possibly correlated to the high potency and efficacy of SCRA compared to cannabis. Pharmacovigilance is a useful tool to measure and monitor illicit drug use, and with appropriate infrastructure and capacity has the potential to contribute to drug policy at a national level.

Therapeutic errors captured by the New Zealand National Poisons Centre: a retrospective audit.

INTRODUCTION Medication errors are one important cause of harm to patients. Information about medication errors can be obtained from diverse sources, including databases administered by poisons centres as part of their routine operation. AIM The aim of this study was to describe the data regarding therapeutic errors captured by the New Zealand National Poisons Centre (NZNPC). METHODS A retrospective study of calls made to the NZNPC between 1 September 2016 and 31 August 2018 was conducted, which involved human patients and were classified as 'therapeutic error' in the NZNPC database. Variables extracted and analysed included the demographics of the individual, the substance(s) involved, and site of exposure. RESULTS During the study period, a total of 43,578 calls were received by the NZNPC, including 5708 (13%) that were classified as 'therapeutic error'. Just over half of the exposures occurred in females, 3197 (56%) and 4826 (85%) of the calls involved a single substance. All age groups were affected and 2074 (37%) of the calls were related to children aged <12 years. A residential environment (n=5568, 97%) was the site of exposure for almost all reported therapeutic errors, most commonly in the patient's own home (n=5207, 91%). DISCUSSION This study provides insights into therapeutic error-related calls to the NZNPC. Almost all errors occurred in the residential setting. Over one-third of the calls involved children. Enhanced data capture and classification methods are needed to determine the types of errors and their possible causes to better inform prevention efforts.

Interventions performed by New Zealand community pharmacists while dispensing prescription medications.

OBJECTIVE: To investigate the number and type of interventions performed by New Zealand community pharmacists when dispensing new prescriptions. METHOD: All community pharmacies in Dunedin, New Zealand (29) were asked to use a tally system to record the types of interventions performed, the time taken and the number of prescription items processed per day. Data was collected for one full week for 20 pharmacies. RESULTS: In total 24,059 prescription items were dispensed by the 20 pharmacies over one week. There were 1,551 separate interventions recorded with a recorded time of 1,684 min. These interventions occurred at a rate of 64 interventions per 1,000 prescription items. Of recorded interventions, bureaucratic and generic substitution problems accounted for 81%. These combined interventions occurred at a rate of 52 per 1,000 prescription items and totalled 50% of the time spent on prescription interventions. Whilst clinical interventions were recorded at a rate of 13 per 1,000 items, they accounted for the remaining 50% of time spent. CONCLUSION: Half of the time spent by community pharmacists in Dunedin, New Zealand on prescription interventions consists of correcting bureaucratic and legal issues, limiting the time pharmacists can spend on clinical services.

Clinical pharmacist facilitators in primary care: a descriptive study of their roles and services provided in general practices of southern New Zealand.

INTRODUCTION Internationally, the inclusion of pharmacists into general practice as clinical pharmacy facilitators has improved patient outcomes. However, clinical pharmacists are relatively new to southern New Zealand general practices and their range of services has not been studied. AIMS To describe the implementation of clinical pharmacist services in general practices in the Southern region; to examine the tasks conducted by clinical pharmacy facilitators; and to determine the characteristics of patients who access this service. METHODS The establishment and development of the clinical pharmacy facilitator role was determined by documentation held within the local Primary Health Organisation. The activities performed by clinical pharmacy facilitators were collected from patient medical records for the period 31 March 2015 to 31 March 2018. To describe the characteristics of patients receiving these services, a retrospective case note review of patients seen by the facilitators was conducted. RESULTS The clinical pharmacy facilitator role was initiated with three pharmacists in three geographical locations across the region. Within 18 months, the number of facilitators was increased to eight. As a result of collaboration with the general practice team, 42% of referrals came from general practitioners directly. Overall, 2621 medicine-related problems were identified in 2195 patients. Dosage adjustment was the most common recommendation made by pharmacy facilitators. They consulted mostly older patients and patients taking five or more medicines. DISCUSSION With effective collaboration, clinical pharmacy facilitators can play a key role in optimisation of medicines therapy.

Analysis of medications returned to community pharmacies.

BACKGROUND: There are many causes of medication waste, including excess supply, treatment changes, and patient nonadherence to therapy. Investigating medication returns may indicate areas for targeting interventions to reduce waste. OBJECTIVE: To identify and quantify the types and amounts of medications returned to community pharmacies and, specifically, to quantify the percentage of medication returned from the original dispensing, its therapeutic category, and reasons for not being used. METHODS: Unsolicited medication returned for disposal to the 24 community pharmacies in the Taranaki region (approximately 37,000 households) of New Zealand over a 6-week period was analyzed. The results were entered into a database, recording medication, amount originally issued (if known), date of issue, Anatomical Therapeutic Chemical (ATC) classification, and reason for nonuse. Cross-tabulation of ATC category versus percentage returned as well as ATC category versus reason for returns was performed. Adjusted standardized residuals were investigated to determine specific cells that were in excess of the expected counts. RESULTS: Complete information was available for 2704 items. The majority (51%) of returns contained 75-100% of the original dispensed amount of medication. For the respiratory category, 77% of the returns were in the 75-100% group, significantly more than for any other therapeutic group. Reasons for returns were recorded as bereavement (22%), surplus to requirements (17%), expired (8%), medication change (11%), dose change (3%), and unknown (39%). The cardiovascular group and respiratory groups had a higher rate of returned drugs due to medication changes and surplus to requirements, respectively. CONCLUSIONS: The majority of returned medications contained greater than 75% of the original amount issued. Identification of therapeutic groups having higher rates of returns due to medication changes or surplus to requirements may suggest areas to target to reduce medication waste.

Distribution of fibroblast growth factor-2 (FGF-2) within model excisional wounds following topical application.

OBJECTIVE: To characterise the magnitude and distribution of fibroblast growth factor-2 (FGF-2) following topical application in hypromellose gel and film formulations or a solution in an animal wound model, in order to assess the potential of this route for treatment of chronic wounds. METHOD: Topical formulations of FGF-2 were applied to punch biopsy wounds, and FGF-2 levels within the wound measured. Each 12 mm diameter wound received 0.3 microg FGF-2 in solution, a 7% (w/w) hypromellose gel, a dried hypromellose film on Melolin-backing or a saline control. After 2, 5 or 8 h the wounds were horizontally dissected into four sections (surface granulation, subcutaneous fat, superficial muscle and deep muscle) which were then analysed for FGF-2 concentration using ELISA. Confocal microscopy was used to evaluate the distribution of FGF-2 within the wound. KEY FINDINGS: There were significant differences in the mean FGF-2 levels with respect to formulation and time following application (P < 0.05). FGF-2 penetrated faster into tissue when formulated as a solution than as a gel or a film. There did not appear to be a significant difference between the gel and the film with respect to total concentrations achieved in the tissue, although confocal microscopy showed differences in FGF-2 distribution within the wound. CONCLUSIONS: Delivery of FGF-2 to wounds in a solution gave the greatest increase in tissue FGF-2 concentration when measured by ELISA and visualised using confocal microscopy. Gel and film formulations prolonged the release of FGF-2 into the wound, although FGF-2 levels were not significantly different from controls when measured by ELISA. Confocal microscopy highlighted the differences in the penetration and distribution of the FGF-2 within the wound when released from different formulations.
