Does the type of pharmacy used influence medication adherence? A retrospective observational study in Aotearoa, New Zealand.

Background: Community pharmacies in New Zealand have varying ownership and operational structures. Unlike independent pharmacies, corporate and hybrid pharmacies do not charge prescription copayments. Objectives: This research aimed to determine whether people receiving free prescriptions from corporate and hybrid pharmacies (via copayment waiver) have greater medication adherence than the users of independent pharmacies. Methods: A nationwide, retrospective, observational study linked 1 year of dispensing data (1/05/2022 to 30/04/2023) from the Pharmaceutical Collection to patient enrollment data using a National Health Index number to identify demographics of different pharmacy-type users. People were assigned to a particular type of pharmacy if they collected at least 70% of their prescriptions from there; if they did not meet this threshold, they were defined as mixed users. People were classified as adherent if dispensing data showed they collected their supply of medication to cover at least 80% of the study period. Results: The sample captured 218,080 people taking at least 1 diabetes medication, with a total of 360,079 unique medications being included in the analysis. The majority, 156,893, used independent pharmacies. The type of pharmacy used was shown to be a significant predictor of adherence. Corporate and hybrid pharmacy users were 0.90 (95% CI 0.88 to 0.93) and 0.93 (95% CI 0.90 to 0.96) times as likely be adherent than the users of independent pharmacies. Mail order pharmacy users were the most likely to be adherent, whereas mixed pharmacy users were the least likely to be adherent. Conclusions: Our findings suggest that prescription copayments provided by corporate and hybrid pharmacies are not the most significant barrier to medication adherence. Further research may identify more efficient ways of improving medication adherence than removing prescription copayments for all.

Impact of removing prescription co-payments on the use of costly health services: a pragmatic randomised controlled trial.

OBJECTIVES: To determine whether exempting people (with high health needs and living in areas of high deprivation) from a $5 prescription charge reduces hospital use. DESIGN: Two-group parallel prospective randomised controlled trial. SETTING: People living in the community in various regions of New Zealand. PARTICIPANTS: One thousand sixty one people who lived in areas of high socioeconomic deprivation, and either took medicines for diabetes, took antipsychotic medicines, or had chronic obstructive pulmonary disease (COPD). Of the 1053 who completed the study, just under half (49%) were Maori. INTERVENTIONS: Participants were individually randomized (1-1 ratio) to either be exempted from the standard $5 charge per prescription item for one year (2019-2020) (n = 591) or usual care (n = 469). Those in the intervention group did not pay the standard NZ$5 charge, and pharmacies billed the study for these. Participants continued to pay any other costs for prescription medicines. Those in the control group continued to pay all prescription charges for the year although they may have received one-off assistance from other agencies. MAIN OUTCOME MEASURES: The primary outcome was length of stay (hospital bed-days). Secondary outcomes presented in this paper included: all-cause hospitalisations, hospitalisations for diabetes/mental health problems/COPD, deaths, and emergency department visits. RESULTS: The trial was under-powered because the recruitment target was not met. There was no statistically significant reduction in the primary outcome, hospital bed-days (IRR = 0.68, CI: 0.54 to 1.05). Participants in the intervention group were significantly less likely to be hospitalised during the study year than those in the control group (OR = 0.70, CI: 0.54 to 0.90). There were statistically significant reductions in the number of hospital admissions for mental health problems (IRR = 0.39, CI: 0.17 to 0.92), the number of admissions for COPD (IRR = 0.37, CI: 0.16 to 0.85), and length of stay for COPD (IRR 0.20, CI: 0.07 to 0.60). Apart from all-cause mortality and diabetes length of stay, all measures were better for the intervention group than the control group. CONCLUSIONS: Eliminating a small co-payment appears to have had a substantial effect on patients' risk of being hospitalised. Given the small amount of revenue gathered from the charges, and the comparative large costs of hospitalisations, the results suggest that these charges are likely to increase the overall cost of healthcare, as well as exacerbate ethnic inequalities.

Target users' acceptance of a pharmacist-led prescribing service for pre-exposure prophylaxis (PrEP) for human immunodeficiency virus (HIV).

Background: Pre-exposure prophylaxis (PrEP) for human immunodeficiency virus (HIV) is a highly effective way to reduce virus transmission. There have been increasing calls to improve access to PrEP in Canada. One way to improve access is by having more prescribers available. The objective of this study was to determine target users' acceptance of a PrEP-prescribing service by pharmacists in Nova Scotia. Methods: A triangulation, mixed-methods study was conducted consisting of an online survey and qualitative interviews underpinned by the Theoretical Framework of Acceptability (TFA) constructs (affective attitude, burden, ethicality, intervention coherence, opportunity cost, perceived effectiveness and self-efficacy). Participants were those eligible for PrEP in Nova Scotia (men who have sex with men or transgender women, persons who inject drugs and HIV-negative individuals in serodiscordant relationships). Descriptive statistics and ordinal logistic regression were used to analyze survey data. Interview data were deductively coded according to each TFA construct and then inductively coded to determine themes within each construct. Results: A total of 148 responses were captured by the survey, and 15 participants were interviewed. Participants supported pharmacists' prescribing PrEP across all TFA constructs from both survey and interview data. Identified concerns related to pharmacists' abilities to order and view lab results, pharmacists' knowledge and skills for sexual health and the potential for experiencing stigma within pharmacy settings. Conclusion: A pharmacist-led PrEP-prescribing service is acceptable to eligible populations in Nova Scotia. The feasibility of PrEP prescribing by pharmacists should be pursued as an intervention to increase access to PrEP.

Community pharmacists' acceptance of prescribing pre-exposure prophylaxis (PrEP) for human immunodeficiency virus (HIV).

Background: Pre-exposure prophylaxis (PrEP) for human immunodeficiency virus (HIV) prevention is highly effective. Pharmacists can increase PrEP accessibility through pharmacist prescribing. This study aimed to determine pharmacists' acceptance of a pharmacist PrEP prescribing service in Nova Scotia. Methods: A triangulation mixed methods study consisting of an online survey and qualitative interviews was conducted with Nova Scotia community pharmacists. The survey questionnaire and qualitative interview guide were underpinned by the 7 constructs of the Theoretical Framework of Acceptability (affective attitude, burden, ethicality, opportunity costs, intervention coherence, perceived effectiveness and self-efficacy). Survey data were analyzed descriptively and with ordinal logistic regression to determine associations between variables. Interview transcripts were deductively coded according to the same constructs and then inductively coded to identify themes within each construct. Results: A total of 214 community pharmacists completed the survey, and 19 completed the interview. Pharmacists were positive about PrEP prescribing in the constructs of affective attitude (improved access), ethicality (benefits communities), intervention coherence (practice alignment) and self-efficacy (role). Pharmacists expressed concerns about burden (increased workload), opportunity costs (time to provide the service) and perceived effectiveness (education/training, public awareness, laboratory test ordering and reimbursement). Conclusion: A PrEP prescribing service has mixed acceptability to Nova Scotia pharmacists yet represents a model of service delivery to increase PrEP access to underserved populations. Future service development must consider pharmacists' workload, education and training as well as factors relating to laboratory test ordering and reimbursement.

Medication risk management and health equity in New Zealand general practice: a retrospective cross-sectional study.

BACKGROUND: Despite an overt commitment to equity, health inequities are evident throughout Aotearoa New Zealand. A general practice electronic alert system was developed to notify clinicians about their patient's risk of harm due to their pre-existing medical conditions or current medication. We aimed to determine whether there were any disparities in clinician action taken on the alert based on patient ethnicity or other demographic factors. METHODS: Sixty-six New Zealand general practices from throughout New Zealand participated. Data were available for 1611 alerts detected for 1582 patients between 1 and 2018 and 1 July 2019. The primary outcome was whether action was taken following an alert or not. Logistic regression was used to assess if patients of one ethnicity group were more or less likely to have action taken. Potential confounders considered in the analyses include patient age, gender, ethnicity, socio-economic deprivation, number of long term diagnoses and number of long term medications. RESULTS: No evidence of a difference was found in the odds of having action taken amongst ethnicity groups, however the estimated odds for Maori and Pasifika patients were lower compared to the European group (Maori OR 0.88, 95 %CI 0.63-1.22; Pasifika OR 0.88, 95 %CI 0.52-1.49). Females had significantly lower odds of having action taken compared to males (OR 0.76, 95 %CI 0.59-0.96). CONCLUSIONS: This analysis of data arising from a general practice electronic alert system in New Zealand found clinicians typically took action on those alerts. However, clinicians appear to take less action for women and Maori and Pasifika patients. Use of a targeted alert system has the potential to mitigate risk from medication-related harm. Recognising clinician biases may improve the equitability of health care provision.

Recruiting people facing social disadvantage: the experience of the Free Meds study.

BACKGROUND: Researching access to health services, and ways to improve equity, frequently requires researchers to recruit people facing social disadvantage. Recruitment can be challenging, and there is limited high quality evidence to guide researchers. This paper describes experiences of recruiting 1068 participants facing social disadvantage for a randomised controlled trial of prescription charges, and provides evidence on the advantages and disadvantages of recruitment methods. METHODS: Those living in areas of higher social deprivation, taking medicines for diabetes, taking anti-psychotic medicines, or with COPD were eligible to participate in the study. Several strategies were trialled to meet recruitment targets. We initially attempted to recruit participants in person, and then switched to a phone-based system, eventually utilising a market research company to deal with incoming calls. We used a range of strategies to publicise the study, including pamphlets in pharmacies and medical centres, media (especially local newspapers) and social media. RESULTS: Enrolling people on the phone was cheaper on average than recruiting in person, but as we refined our approach over time, the cost of the latter dropped significantly. In person recruitment had many advantages, such as enhancing our understanding of potential participants' concerns. Forty-nine percent of our participants are Maori, which we attribute to having Maori researchers on the team, recruiting in areas of high Maori population, team members' existing links with Maori health providers, and engaging and working with Maori providers. CONCLUSIONS: Recruiting people facing social disadvantage requires careful planning and flexible recruitment strategies. Support from organisations trusted by potential participants is essential. REGISTRATION: The Free Meds study is registered with the Australian and New Zealand Clinical Trials Registry ( ACTRN12618001486213 ).

Effectiveness of patient decision aids in women considering psychotropic medication use during pregnancy: a literature review.

Women face complicated decisions regarding psychotropic medication use during pregnancy. Patient decision aids (PDAs) could be a valuable tool to assist with decision-making. The objective of this review was to evaluate the effectiveness of PDAs in this population. A systematic search of the literature was conducted using PRISMA guidelines. Three major databases were searched to identify articles published between 2006 and June 2020. Studies were included if they evaluated use of a PDA for women considering medication for mental illness during pregnancy. A total of 4629 titles were returned from the search; however, only three studies met inclusion criteria and were selected for analysis. Two were pilot randomised controlled trials in women considering antidepressant use during pregnancy, and one was a non-randomised study in women considering medication for the treatment of opioid use disorder (OUD). The PDAs had good acceptability across all three studies. The randomised trials assessed knowledge, decisional conflict, depression, and anxiety, with non-significant trends towards reduced decisional conflict and anxiety in the PDA groups. PDAs have the potential to assist women with mental illnesses to make decisions regarding medication use during pregnancy; however, current evidence is too limited to evaluate the effectiveness of PDAs for this population.

Examining non-medical prescribing trends in New Zealand: 2016-2020.

BACKGROUND: Population growth and general practitioner workforce constraints are creating increasing demand for health services in New Zealand (NZ) and internationally. Non-medical prescribing (NMP) is one strategy that has been introduced to help manage this. Little is known about the NMP practice trends in NZ. The aim of this study was to provide a current overview of the scale, scope, and trends of NMP practice in NZ. METHODS: All claims for community dispensed medicines prescribed by a non-medical prescriber were extracted from the NZ Pharmaceutical Collection for the period 2016-2020. Patient demographics were retrieved from the Primary Health Organisation enrolment collection. These national databases contain prescription information for all subsidised community pharmacy medicines dispensed and healthcare enrolment data for 96% of New Zealanders. RESULTS: The proportion of prescriptions written by all NMP providers and patients receiving NMP prescriptions increased each year from 1.8% (2016) to 3.6% (2019) and 8.4% (2016) to 14.4% (2019) respectively. From 2016 to 2019, the proportion of NMP patients who had at least one NMP prescription increased from 26% to 39% for nurse prescribers, from 1% to 9% for pharmacist prescribers, from 2% to 3% for dietitian prescribers, and decreased from 47% to 22% for dentists, and from 20% to 12% for midwives. The most commonly prescribed medicines were antibiotics (amoxicillin, amoxicillin with clavulanic acid, and metronidazole), and analgesics (paracetamol, and codeine phosphate). While some NMP providers were prescribing for patients with greater health needs, all NMP providers could be better utilised to reach more of these patients. CONCLUSIONS: This study highlights that although the NMP service has been implemented in NZ, it has yet to become mainstream healthcare practice. This work provides a baseline to evaluate the NMP service moving forward and enable policy development. Improved implementation and integration of primary care NMP services can ensure continued access to prescribing services and medicines for our communities.

Higher BMI Confers a Long-Term Functional Status Advantage in Elderly New Zealand European Stroke Patients.

OBJECTIVE: Obesity is a risk factor for ischaemic stroke but provides a survival advantage. The relationship between body mass index (BMI) and long-term function is less clear. The presence of an obesity paradox can inform clinical care and identify vulnerable patients who need additional support post-stroke. MATERIALS AND METHODS: This study used linked health administrative data of a population based cohort of adult patients who experienced an ischaemic stroke between 2012 and 2017 in New Zealand. Patient demographics were obtained from the National Minimum Dataset (NMDS). BMI and Activities of Daily Living scores (ADLs) for the same patients were obtained from the International Resident Assessment Instrument (InterRAI™). RESULTS: Linked data was obtained for 3731 patients. Ninety-five percent of the cohort were aged 65 or older and the average age of stroke was 84.5 years. The majority of patients (55%) identified as New Zealand European. Beta regression indicated BMI and European ethnicity were negatively associated with ADL score. Univariate analysis confirmed patients with underweight stroke had significantly higher ADL scores than other BMI categories (p<0.001), however functional status for patients with overweight and obesity were comparable. Further, Asian and Pacific Peoples had higher ADL scores than Europeans (p<0.05). A higher BMI was advantageous to all ADL subscores. CONCLUSION: An abridged obesity paradox was evident in our cohort of stroke patients where a BMI in the overweight, but not obese range conferred a long-term functional status advantage. Collectively these results suggest underweight and non-European patients may require additional supportive clinical care post-stroke.

The Use of Gentamicin for Treatment of Urogenital and Extragenital Gonorrhea: A Systematic Review of Efficacy Data.

OBJECTIVE: To evaluate clinical efficacy data for gentamicin in the treatment of gonorrhea. DATA SOURCES: A keyword search of PubMed (1966 to April 2020), EMBASE (1947 to April 2020), and International Pharmaceutical Abstracts (1970 to April 2020) was conducted. The electronic search was supplemented with manual screening of references from identified articles and a search of ClinicalTrials.gov to identify ongoing trials. STUDY SELECTION AND DATA EXTRACTION: Comparator and noncomparator studies reporting microbiological outcomes of treatment with gentamicin for gonorrhea in humans were included. Data extracted included study year, authors, aim, setting, population, dosing protocols, and outcome results. Risk of bias was assessed according to the Cochrane Risk of Bias Assessment Tool. DATA SYNTHESIS: A total of 407 articles were identified, of which 11 met inclusion criteria. Two studies were randomized controlled trials, and 1 additional randomized noncomparator study was identified. All other studies were nonrandomized and noncomparator in nature. The highest quality evidence suggests that gentamicin is not noninferior to ceftriaxone (both in addition to azithromycin) for treatment of gonorrhea but may achieve cure rates >90%. Conflicting evidence exists regarding the efficacy of gentamicin-based regimens for the specific treatment of extragenital gonorrhea. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: Results of this review could affect patient care and clinical practice because they clearly demonstrate the role of gentamicin for the treatment of gonorrhea as a second-line agent. Future research should confirm findings, especially for the role of gentamicin in extragenital infections. CONCLUSIONS: Gentamicin-based regimens should be reserved for second-line treatment of urogenital and extragenital gonorrhea infections.

Developmental outcomes at age four following maternal antiepileptic drug use.

We investigated whether prenatal antiepileptic drug (AED) exposure was associated with adverse outcomes in the Before School Check (B4SC) assessments, particularly the assessments measuring neurodevelopment. Children exposed to AEDs were identified by linking women dispensed AEDs in the Pharmaceutical Collection to births recorded on the National Minimum Dataset (NMDS). Multinomial logistic regression was used to estimate adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) for outcomes of the parent-completed Parental Evaluation of Developmental Status (PEDS) questionnaire and Strengths and Difficulties Questionnaire (SDQ), after adjusting for gender, ethnicity, and socioeconomic deprivation. Between 2012 and 2016, 606 children with a mother who had been dispensed one or more AEDs during pregnancy had taken part in the B4SC. Prenatal exposure to sodium valproate (n = 161) or lamotrigine (n = 149) monotherapy was associated with an increased risk of having an abnormal SDQ - parent-completed (SDQP) score, ≥17 - indicating emotional or behavioral concerns (9.32% of children exposed to sodium valproate monotherapy had an abnormal score; aRR: 2.11; 1.23-3.63; lamotrigine 8.05%; aRR: 2.21; 1.21-4.02). Prenatal exposure to carbamazepine monotherapy (n = 201) was not associated with an increased risk of having an abnormal total SDQP score but was associated with increased risks in the individual domains of the SDQP. Prenatal exposure to AED polytherapy (n = 57) was associated with the highest risk of abnormal SDQP scores (17.54% of children exposed to polytherapy had abnormal scores; aRR: 2.75; 1.25-6.02). Prenatal exposure to sodium valproate and lamotrigine is associated with an increased risk of concerns about emotional and behavioral development being reported by parents in a neurodevelopmental screening program. Additional investigation is required into why significant differences between AEDs were not seen in this study.

General practitioners and gestational weight management.

This study aimed to explore the knowledge and practice of New Zealand (NZ) general practitioners (GPs) regarding gestational weight gain (GWG), and identify the current level of involvement NZ GPs have in early pregnancy care. In NZ, the majority of antenatal care is carried out by a midwife lead maternity carer (LMC), with government funding for one first trimester appointment with the woman's GP. A mixed methods survey was conducted on a randomly selected sample of 470 NZ GPs. Survey responses were analysed using descriptive statistics and a general inductive approach for free text data. A total of 200 GPs (42.5%) responded. Half of the GPs regularly saw women in their early pregnancy, but the discussion of recommended GWG was uncommon. The knowledge and practice regarding GWG was not in keeping with the national guidance. Free text analysis identified time pressures, funding issues, loss of skill and a poor communication with LMCs as the barriers to care. Education, promotion of guidance, appropriate funding and improved communication between carers are critical to address the current shortfalls. Impact statement What is already known on this subject? Excess gestational weight gain (GWG) is a modifiable risk factor for the vast majority of obstetric complications. It is more likely in pregnant women who overestimate the appropriate GWG. Current literature suggests that the antenatal advice on GWG is insufficient. In New Zealand (NZ), there is provision for one funded general practitioner (GP) appointment in the first trimester, in addition to that provided by the lead maternity carer (LMC). GPs are expected to provide a range of services at this appointment including health information and education on nutrition. What the results of this study add? The results demonstrate that while GPs are seeing women in early pregnancy, specific GWG discussion is uncommon. The results suggest knowledge gaps are partially responsible for this along with GP self-reported frustrations at lack of time, funding issues, loss of relevant skills, and minimal contact with LMCs. What the implications are of these findings for clinical practice and/or further research? Mediocre gestational weight management is not acceptable in our current obesity climate. This research identifies a need to improve GP knowledge on the management of GWG as part of the wider maternity healthcare team, address GP concerns regarding funding for their provision of maternity care, and aid communication between GPs and LMCs.

Antiepileptic drug exposure in pregnancy and pregnancy outcome from national drug usage data.

BACKGROUND: Antiepileptic drugs (AEDs) are used by pregnant women to manage conditions such as epilepsy and bipolar disorder even though they pose a risk to the developing foetus. This study aimed to determine the overall use of AEDs by women during their childbearing years and women who are pregnant and the association between AED use and rates of pregnancy termination and spontaneous abortion. METHODS: Retrospective population based cohort study using administrative databases in New Zealand between 2008 and 2014. Women who had been pregnant were identified by the National Minimum Dataset and were linked to the Pharmaceutical Collection to obtain information on use of AEDs. Women aged between 15 and 45 years dispensed AEDs were identified in the Pharmaceutical Collection. RESULTS: There was an increase in the number of women of child-bearing potential prescribed AEDs, from 9 women per 1000 women in 2008 to 11.4 women per 1000 women in 2014. Women who had been dispensed an AED had an increased rate of spontaneous abortion 8.97 spontaneous abortions per 100 pregnancies, compared with, 6.31 per 100 pregnancies (risk ratio 1.42, 95% CI 1.40 to 1.44), and a decreased rate of pregnancy termination, 18.51 terminations per 100 pregnancies compared with 19.58 per 100 pregnancies (risk ratio 1.95, 95% CI 0.94-0.96). CONCLUSION: Use of newer AEDs is increasing in women of child-bearing potential in New Zealand leading to an overall increase in AED use in this group despite a fall in the use of older AEDs. AED use is this study was associated with an increased risk of spontaneous abortion and decreased rate of pregnancy termination, however confounding by indication could not be excluded.

Service provision in the wake of a new funding model for community pharmacy.

BACKGROUND: Recently, New Zealand has taken a system wide approach providing the biggest reform to New Zealand community pharmacy for 70 years with the aim of providing more clinically orientated patient centred services through a new funding model. The aim of this study was to understand the types of services offered in New Zealand community pharmacies since introduction of the new funding model, what the barriers are to providing these services. METHOD: A survey of all community pharmacies were undertaken between August, 2014 and February, 2015. Basic descriptive statistics were completed and group comparisons were made using the chi squared test with significance set at p < 0.05. RESULTS: 528 responses were received. Education and advice on prescription and non-prescription medicines were the two top listed services provided. There were no significant differences in service provision between rural and metro based pharmacies. Many pharmacies were considering introducing new patient centred services. Four of the top ten frequently provided services have no public funding attached. Costs and staff availability are the most common barriers to undertake services, more predominantly in patient centred services. CONCLUSION: This study was the first to provide an evaluation of service provision in response to a new funding model for New Zealand Community Pharmacies. A broad range of services are being undertaken in New Zealand community pharmacies including patient-centred services. A number of barriers to service provision were identified. This study provides a baseline for the current levels of service provision upon which future studies can compare to and evaluate any changes in service provision with differing funding models going forward.

General practitioners and preconception weight management in New Zealand.

BACKGROUND: Childhood obesity is a growing concern internationally and a top priority for the World Health Organization. Preconception overweight, obesity and excess gestational weight gain significantly increase childhood obesity risk. Optimising preconception weight is a key preventative measure toward reducing childhood obesity. In 2014, the New Zealand (NZ) Ministry of Health released guidance for health practitioners on healthy weight gain in pregnancy in an effort to reduce the burden of childhood obesity. AIM: To explore the knowledge and practice of NZ general practitioners (GPs) regarding preconception and gestational weight management. MATERIALS AND METHODS: A nationwide survey was conducted on a randomly selected sample of NZ GPs using a mixed methods approach. Descriptive statistics were used for survey responses and a general inductive approach was applied to the free text data. RESULTS: A total of 200 GPs (42.5%) responded. The majority of GPs were aware of the risks of obesity in pregnancy. Over 50% of GPs reported practice that was not consistent with recommended standards of care. Ministry of Health guidance was known to only 12% of participants. Themes emerging from the free text data included: lack of opportunity for, and awareness of, preconception care; recognition of the importance of this area; and need for further learning. CONCLUSIONS: General practitioners in NZ are not providing optimal preconception care. This research highlights the need for a public health message encouraging preconception counselling and better education of GPs on the topic. This should start with promotion of the Ministry of Health guidance.

Trends, demographics and disparities in outpatient antibiotic consumption in New Zealand: a national study.

OBJECTIVES: Knowledge of the patterns of antibiotic consumption within a population provides valuable information on when, where and to whom antibiotics are prescribed. Such knowledge is critical in informing possible public health interventions to reduce inappropriate antibiotic use. The aims of this study were to (i) determine national patterns of antibiotic consumption, including assessment of seasonal variation in prescribing, and (ii) explore potential associations between antibiotic consumption and patient characteristics, such as age, sex and ethnicity. METHODS: Data on all subsidized antibiotic dispensing in New Zealand between 1 January 2006 and 31 December 2014 were obtained and stratified according to age, sex and ethnicity. Antibiotic dispensing was expressed as the number of DDDs per 1000 population per day (DID). RESULTS: Total antibiotic consumption in New Zealand increased by 49% from 17.3 DID in 2006 to 25.8 DID in 2014. The increase in antibiotic consumption occurred in all ages and amongst all ethnic groups. The use of extended-spectrum penicillins, which almost doubled in the study period, made a major contribution to the overall increase and was highest in young children and in Pacific peoples. Consumption of quinolones increased early in the study period and then declined from 2011 onwards. CONCLUSIONS: Future work should focus on identifying the appropriateness of antibiotic prescribing, particularly for penicillin prescribing in Pacific peoples and children, and on both reducing unwarranted antibiotic use and improving antibiotic selection when therapy is indicated.

Polypharmacy among inpatients aged 70 years or older in Australia.

OBJECTIVES: To investigate medication changes for older patients admitted to hospital and to explore associations between patient characteristics and polypharmacy. DESIGN: Prospective cohort study. PARTICIPANTS AND SETTING: Patients aged 70 years or older admitted to general medical units of 11 acute care hospitals in two Australian states between July 2005 and May 2010. All patients were assessed using the interRAI assessment system for acute care. MAIN OUTCOME MEASURES: Measures of physical, cognitive and psychosocial functioning; and number of regular prescribed medications categorised into three groups: non-polypharmacy (0-4 drugs), polypharmacy (5-9 drugs) and hyperpolypharmacy (≥ 10 drugs). RESULTS: Of 1220 patients who were recruited for the study, medication records at admission were available for 1216. Mean age was 81.3 years (SD, 6.8 years), and 659 patients (54.2%) were women. For the 1187 patients with complete medication records on admission and discharge, there was a small but statistically significant increase in mean number of regular medications per day between admission and discharge (7.1 v 7.6), while the prevalence of medications such as statins (459 [38.7%] v 457 [38.5%] patients), opioid analgesics (155 [13.1%] v 166 [14.0%] patients), antipsychotics (59 [5.0%] v 65 [5.5%] patients) and benzodiazepines (122 [10.3%] v 135 [11.4%] patients) did not change significantly. Being in a higher polypharmacy category was significantly associated with increase in comorbidities (odds ratio [OR], 1.27; 95% CI, 1.20-1.34), presence of pain (OR, 1.31; 1.05-1.64), dyspnoea (OR, 1.64; 1.30-2.07) and dependence in terms of instrumental activities of daily living (OR, 1.70; 1.20-2.41). Hyperpolypharmacy was observed in 290/1216 patients (23.8%) at admission and 336/1187 patients (28.3%) on discharge, and the proportion of preventive medication in the hyperpolypharmacy category at both points in time remained high (1209/3371 [35.9%] at admission v 1508/4117 [36.6%] at discharge). CONCLUSIONS: Polypharmacy is common among older people admitted to general medical units of Australian hospitals, with no clinically meaningful change to the number or classification (symptom control, prevention or both) of drugs made by treating physicians.

Patients' valuation of the prescribing nurse in primary care: a discrete choice experiment.

BACKGROUND: Recently, primary care in the United Kingdom has undergone substantial changes in skill mix. Non-medical prescribing was introduced to improve patient access to medicines, make better use of different health practitioners' skills and increase patient choice. There is little evidence about value-based patient preferences for 'prescribing nurse' in a general practice setting. OBJECTIVE: To quantify value-based patient preferences for the profession of prescriber and other factors that influence choice of consultation for managing a minor illness. DESIGN: Discrete choice experiment patient survey. SETTING AND PARTICIPANTS: Five general practices in England with non-medical prescribing services, questionnaires completed by 451 patients. MAIN OUTCOME MEASURE: Stated choice of consultation. MAIN RESULTS: There was a strong general preference for consulting 'own doctor' for minor illness. However, a consultation with a nurse prescriber with positive patient-focused attributes can be more acceptable to patients than a consultation provided by a doctor. Attributes 'professional's attention to Patients' views' and extent of 'help offered' were pivotal. Past experience influenced preference. DISCUSSION AND CONCLUSION: Respondents demonstrated valid preferences. Preferences for consulting a doctor remained strong, but many were happy to consult with a nurse if other aspects of the consultation were improved. Findings show who to consult is not the only valued factor in choice of consultation for minor illness. The 'prescribing nurse' role has potential to offer consultation styles that patients value. Within the study's limitations, these findings can inform delivery of primary care to enhance patient experience and substitute appropriate nurse prescribing consultations for medical prescribing consultations.

Survey of patients' experiences and perceptions of care provided by nurse and pharmacist independent prescribers in primary care.

BACKGROUND: In the United Kingdom, nurses and pharmacists who have undertaken additional post-registration training can prescribe medicines for any medical condition within their competence (non-medical prescribers, NMPs), but little is known about patients' experiences and perceptions of this service. OBJECTIVE: to obtain feedback from primary care patients on the impact of prescribing by nurse independent prescribers (NIPs) and pharmacist independent prescribers (PIPs) on experiences of the consultation, the patient-professional relationship, access to medicines, quality of care, choice, knowledge, patient-reported adherence and control of their condition. DESIGN: Two cross-sectional postal surveys. SETTING AND PARTICIPANTS: Patients prescribed for by either NIPs or PIPs in six general practices from different regions in England. RESULTS: 30% of patients responded (294/975; 149/525 NIPs; 145/450 PIPs).
