"There's very little that you can do other than refer them to the doctor if you think they've got postnatal depression": Scoping the potential for perinatal mental health care by community pharmacists.

BACKGROUND: Twenty percent of women in the UK develop perinatal mental health (PMH) problems, which have widespread effects on maternal and child health. Community pharmacists are ideally placed to identify PMH problems and refer to other trained healthcare professionals. OBJECTIVE: This study explored community pharmacists' attitudes, current counselling practices, and barriers to providing mental health advice to perinatal women. METHODS: A qualitative focus group study was performed virtually with community pharmacists (n = 11), working in urban settings across London. A topic guide was used to cover current counselling practice, barriers to and confidence in counselling women, and thoughts on potential pharmacist-led perinatal mental health services. The focus groups were recorded, transcribed, and analysed using thematic analysis. RESULTS: Three themes were identified: Doing Mental Health Care; Willing, but Unable; and Introspection and reflection, which were related through a central organising concept of 'Perinatal mental health care as a new frontier for community pharmacy'. It was found that while community pharmacists provide mental health advice to perinatal women and their partners, they lacked confidence, which was related to a lack of knowledge and inadequate training opportunities. Organisational barriers were identified including a lack of a formal referral pathway to existing mental health services and other trained healthcare professionals. Perceptions of opportunities and recommendations for service improvement and change were also garnered. CONCLUSION: This study demonstrates community pharmacists have a potential role within community mental healthcare in identification of PMH problems and providing appropriate advice and support. Upskilling community pharmacists in mental health should be considered to increase knowledge and confidence while formal referral pathways to other trained healthcare professionals and existing services should be established and made available to pharmacists.

Community pharmacy role in children's health in England: Experiences and opinions of parents and young people.

Little is known about the reason behind the underutilisation of community pharmacy (CP) for children. This study explored the experiences, barriers and recommendations of parents/carers and young people regarding their use of CP services for children. Two-stage facilitated, structured, audio-recorded interviews were conducted at each of four CPs in London, England, between May and November 2019 [1 month in each CP]. Parents/carers or young persons (aged 16-18 years) who visited CP for a child-related matter were invited to participate. Interviews were transcribed verbatim. Data were analysed both quantitatively and qualitatively, using thematic analysis to identify themes. In total, 249 (58.2% of 428 eligible) customers agreed to participate and completed the two interviews. Out of these, 82.3% (205/249) reported positive experiences with the CP. The general practitioner (GP) was the preferred healthcare provider for minor ailments (44.6%,111/249), while 35.7% (89/249) would choose CP. Eighty-two participants (33%) visited an Emergency Department in the last 12 months, with 13.4% (11/82) of them visited for cold and cough reasons. Where a child was present with parents/carer (128/249), there was a low level of interaction between children and pharmacists (13.3%, 17/128). Lack of awareness about the CP services provided for children and privacy were among the barriers identified by participants. Advertising of CP services and creating a child-friendly environment were recommendations suggested by participants. The findings of this paper show that CP remains an underutilised health service for children by parents/carers and young persons. More work is needed to increase public awareness of the roles of CP in children's health and well-being.

Trends, geographical variation and factors associated with melatonin prescribing in general practices in England: A practice-level analysis.

An overview of melatonin prescribing trends and variation in England is described in this study. Prescription reimbursement data for melatonin in England were extracted from publicly available primary care datasets between 2008-2019. Melatonin prescribing rates, cost and product license status were described over time. Potential factors associated with melatonin prescribing were investigated using Poisson regression. Melatonin prescribing increased from 2.0 to 19.9 per 1000 people between 2008 and 2019. While prescriptions for licensed products increased from 6.5% to 88.2%, spending on unlicensed products was £10 million and accounted for 23.3% of the total prescription cost in 2019. Practices with a higher proportion of children and older people and those serving more deprived patient populations were associated with a higher rate of prescribing (rate ratio = 1.51, 1.66 and 1.59, respectively). Melatonin prescribing in England has increased exponentially over the last decade, with substantial spending on unlicensed products of unknown quality. Patient-level analysis research is needed.

Pharmacokinetic and pharmacodynamic evidence of adrenaline administered via auto-injector for anaphylactic reactions: A review of literature.

Anaphylaxis is a severe allergic reaction that can lead to death if not treated quickly. Adrenaline (epinephrine) is the first-line treatment for anaphylaxis and its prompt administration is vital to reduce mortality. Following a number of high-profile cases, serious concerns have been raised, both about the optimal dose of intramuscular adrenaline via an auto-injector and the correct needle length to ensure maximal penetration every time. To date, the public data are sparse on the pharmacokinetics-pharmacodynamics of adrenaline administered via an auto-injector. The limited available literature showed a huge variation in the plasma concentrations of adrenaline administered through an auto-injector, as well as variations in the auto-injector needle length. Hence, delivering an effective dose during an anaphylaxis remains a challenge for both patients and healthcare professionals. Collaborative work between pharmacokinetics-pharmacodynamics experts, clinical triallists and licence holders is imperative to address this gap in evidence so that we can improve outcomes of anaphylaxis. In addition, we advise inclusion of expertise of human factors in usability studies given the necessity of carer or self-administration in the uniquely stressful nature of anaphylaxis.

Establishing dose bands for commonly prescribed oral medications for children in the UK: Results of a Delphi study.

OBJECTIVE: To establish weight-based dose bands for commonly used oral medicines, given in liquid forms, for children in the UK that could be used for prescribing and administering accurate and safe drug doses. METHODS: A list of commonly prescribed, oral liquid medications was established from the medication dispensing database of four UK hospitals and a primary care database. The evidence base of currently used dose regimens for each drug was identified from paediatric reference books, summary of product characteristics and the literature. Then, weight-based dose bands were developed and a modified Delphi process was used to achieve healthcare professional consensus about the suggested dose bands for each drug. RESULTS: Forty-six experts in paediatric medicines participated in the Delphi process (mean years of experience 17.3 ± 9.4 [standard deviation]) and assessed 45 oral liquid drugs in total. Four categories of weight-based dose bands were established: drugs with two dose bands (17.8%, 8/45), drugs with three dose bands (64.4%, 29/45), drugs with four dose bands (15.6%, 7/45) and drugs with five dose bands (2.2%, 1/45). The 46 participants reached consensus on all the suggested dose bands for 53.3% (24/45) of the drugs. Consensus was reached in the first round of the Delphi process for 91.7% (22/24) of the drugs and after two rounds for two drugs. No agreement was achieved on any of the suggested dose bands for 26.7% (12/45) of the drugs. CONCLUSION: This study provides healthcare professionals with a set of recommended weight-based dose bands for commonly prescribed oral liquid drugs for children. These bands could establish the basis for change in clinical practice to reduce dosing errors and improve healthcare for children.

Feasibility of developing children's Pill School within a UK hospital.

OBJECTIVE: We assessed the feasibility of introducing an intervention (children's Pill School-PS) within a UK hospital to provide swallowing training for children, identified the proportion of children who can be switched from oral liquid medicines to pills and assessed children/parents' opinions about the PS training. METHODS: 30 inpatient children (aged 3-18 years; taking oral liquid medicines; their liquid medications assessed suitable for switching to pills; can (and their parents) speak/understand English were included. Training sessions were delivered using hard sweets of different sizes. RESULTS: 87% (26) of children successfully learnt how to swallow pills after one training session (mean duration 14.5 min), and 92% (24) were discharged on pills. 75 prescribed oral liquid medications were deemed suitable for switching to pills. Of these, 89% (67) were switched successfully. CONCLUSION: Children as young as 3 years were successful in swallowing pills after training. Providing children PS training session within hospital is feasible and acceptable to children and their parents.

Evaluation of the practice of dose-rounding in paediatrics.

OBJECTIVES: To investigate the rounding of prescribed drug doses for paediatric administration. METHODS: A cross-sectional medication chart review was conducted at a UK paediatric hospital. Proposed administration dose volumes were calculated for prescribed doses using available manufactured liquids measured with oral and intravenous syringes. Resulting percentage deviations in doses administered were calculated. RESULTS: Of 2031 doses observed, 524 (25.8%) required rounding. The majority of which were for children aged 1-12 months. Twenty-seven rounded doses deviated from the prescribed dose by more than 10%. CONCLUSION: This study highlights the impact of dose-rounding in paediatrics and the need for standardisation.

GAPPS (Grading and Assessment of Pharmacokinetic-Pharmacodynamic Studies) a critical appraisal system for antimicrobial PKPD studies - development and application in pediatric antibiotic studies.

Introduction: There are limited data on optimal dosing of antibiotics in different age groups for neonates and children. Clinicians usually consult pediatric formularies or online databases for dose selection, but these have variable recommendations, are usually based on expert opinion and are not graded based on the existing pharmacokinetic-pharmacodynamic (PKPD) studies. We describe here a potential new tool that could be used to grade the strength of evidence emanating from PKPD studies.Areas covered: A scoring system was developed (GAPPS tool) to quantify the strength of each PK assessment and rate the studies quality in already published articles. GAPPS was evaluated by applying it to pediatric PKPD studies of antibiotics from the 2019 Essential Medicines List for children (EMLC), identified through a search of PubMed.Expert opinion: Evidence for most antibiotic dose selection decisions was generally weak, coming from individual PK studies and lacked PKPD modeling and simulations. However, the quality of evidence appears to have improved over the last two decades.Incorporating a formal grading system, such as GAPPS, into formulary development will provide a transparent tool to support decision-making in clinical practice and guideline development, and guide PKPD authors on study designs most likely to influence guidelines.

Pediatric pharmacokinetics of the antibiotics in the access and watch groups of the 2019 WHO model list of essential medicines for children: a systematic review.

Introduction: Pharmacokinetic-pharmacodynamic (PK-PD) studies of antibiotics in pediatrics are limited. Pediatric dosing regimens for many antimicrobial drugs have been historically derived from adult pharmacokinetic data. Most pediatric formularies and dosing guidelines globally are expert-based and provide no rationale for the recommended doses, leading to heterogeneous guidance.Areas covered: We systematically reviewed the current dosing for 28 antibiotics listed in the Access and Watch groups of the 2019 World Health Organization (WHO) Essential Medicines List for children (EMLc). PubMed and EMBASE were searched for all PK-PD and pharmacological studies in pediatrics up to May 2018. In total, 262 pediatric related articles were deemed eligible. The most studied drugs were those where therapeutic drug monitoring is routine (aminoglycosides, glycopeptides) and study reporting detail was variable, with only 60.0% using the PK-PD results in make dosing recommendations. Based on this evidence, dose recommendations for each antibiotic were made.Expert opinion: We provide an up-to-date review of the limited available evidence on pediatric dosing for the 28 commonly prescribed antibiotics in the 2019 WHO EMLc. We propose synthesized dosing recommendations for those antibiotics administered systemically for the treatment of serious infections. Further PK-PD studies in children, particularly with underlying conditions, are needed.

Impact of the e-prescribing system on the incidence and nature of drug-related problems in children in a Saudi hospital.

OBJECTIVES: To determine the impact of a computerised physician order entry (CPOE) system on the drug-related problems' (DRPs) incidence and characteristics in hospitalised children in a Saudi hospital, and to compare DRPs incidence pre-/post-CPOE implementation. METHODS: An observational study. DRPs were identified by pharmacists, reviewing children's (0-14 years) medical records on CPOE system, in paediatric wards and/or attending emergency department. DRPs preventability and severity were assessed. RESULTS: A total of 657 paediatric patients were included, with 235 (35.8%) experienced 328 DRPs, majority were preventable (99.7%, 327). Difference in DRP incidence pre- and post-CPOE implementation (44.8% versus 35.8%, P < 0.01) was significant. CONCLUSION: The CPOE system has significantly reduced DRPs incidence in children in the study hospital.

Standardised concentrations of morphine infusions for nurse/patient-controlled analgesia use in children.

BACKGROUND: Standardizing concentrations of intravenous infusions enables pre-preparation and is effective in improving patient safety by avoiding large deviations from the prescribed concentration that can occur when infusions are made individually in wards and theatres. The use of pre-prepared morphine standardized concentration infusions for paediatric nurse/patient-controlled analgesia (N/PCA) has not been previously investigated. We aimed to establish, implement and evaluate standardized concentrations of morphine in pre-filled syringes (PFS) for use in paediatric N/PCA. METHODS: Concentrations of morphine in PFS for N/PCA were identified that accommodated dosage variation across a 1-50 kg weight range. The use of infusions in PFS was implemented and evaluated using mixed methods involved direct observation of healthcare professionals (HCPs), focus groups and failure mode and effects analysis, a HCP survey and medication incident reports analysis. RESULTS: Standardized concentrations, 3 mg, 10 mg and 50 mg morphine in 50 mL sodium chloride 0.9%, delivered prescribed continuous and bolus doses using programmable smart pumps with variable infusion rates. During the implementation, 175 morphine pre-prepared infusions were administered to 157 children (9.4 ± 5.1 years) in theatres and wards. Time taken to set up a N/PCA was 3.7 ± 1.7 min, a reduction of one third compared with the previous system. The number of incidents associated with N/PCA infusions was reduced by 41.2%, and preparation errors were eliminated. HCPs reported using morphine PFS was an easier and safer system. CONCLUSION: A system using pre-prepared standardized concentrations of morphine for paediatric N/PCA was implemented successfully and sustainably.

Current practice of preparing morphine infusions for nurse/patient-controlled analgesia in a UK paediatric hospital: healthcare professionals' views and experiences.

OBJECTIVE: To explore the views and experiences of healthcare professionals (HCPs) regarding the preparation of morphine infusions for nurse/patient-controlled analgesia (N/PCA). METHODS: Three focus groups were conducted with HCPs (anaesthetists, nurses in theatres and wards) at one UK children's hospital. Focus groups were transcribed verbatim and content analysis was used to identify themes. RESULTS: A variety of approaches are used to prepare morphine infusions. A lack of appreciation of the excess volume present in morphine ampoules that nominally contain 1 or 2 mL was identified. Other sources of error were miscalculation, complexity of the multistep procedure, distractions and time pressure. Participants suggested that 'ready-to-use' prefilled syringes and preprogrammed syringe pumps would improve practice and minimise the risk of error. CONCLUSIONS: Risks associated with the preparation of infusions for paediatric N/PCA, in particular non-appreciation of the overage (excess volume) in morphine ampoules, raise concerns about the accuracy of current practices.

Analgesic Drug Prescription Patterns on Five International Paediatric Wards.

AIM: Analgesic and anti-inflammatory drugs are frequently prescribed in paediatrics. Prescribing and dosing patterns in hospitalised children are not well known. This study explores analgesic drug utilisation on five paediatric wards and discusses its findings in comparison with World Health Organization (WHO) guidelines. METHOD: A sub-analysis of a prospective, multicentre, observational cohort study was undertaken. Prescription data of children aged up to ≤18 years were collected between October 2008 and December 2009 on paediatric general medical wards in five hospitals in Australia, Germany, the United Kingdom (UK), Hong Kong (HK) and Malaysia. Analgesic drug prescriptions were analysed for prescribing patterns in terms of dosing, frequency and route of administration. Dosing data were compared with local recommendations and WHO guidelines for children. RESULTS: In the study cohort, 56.8 % (726/1278) of paediatric patients received at least one analgesic drug prescription (1227 prescriptions). The median age of patients with analgesics was 2.2 years [interquartile range (IQR) 0.8-7.3], and the median number of prescriptions per patient was one (IQR 1-2). The most commonly prescribed drugs were oral paracetamol (45.9 %, 563/1227) and oral ibuprofen (19.9 %, 244/1227). Daily doses of paracetamol ranged from 30 mg/kg/day in Germany to 67-68 mg/kg/day in the UK and HK (p < 0.05). For ibuprofen, single doses ranged from 5-6 mg/kg in HK and the UK to 10 mg/kg in Germany and Australia (p < 0.001). Opioid use prevalence was statistically different between the centres and ranged from 0 to 17.6 % (p < 0.001). CONCLUSION: This study provides a comprehensive overview of analgesic drug use of hospitalised children. Similar to primary care data, paracetamol is the most commonly used analgesic. As recommended by WHO guidelines, oral medication was favoured and opioids used in addition to paracetamol and ibuprofen. Overall drug utilisation was in line with local recommendations and WHO guidelines. Differences in use of paracetamol and ibuprofen among countries were seen, indicating that safety concerns are perceived differently. More large-scale safety studies are needed.

EVALUATION OF THE CURRENT PRACTICE OF DELIVERING INTRAVENOUS OPIOIDS INFUSIONS IN A UK PAEDIATRIC HOSPITAL.

INTRODUCTION: Opiate intravenous infusions are the therapy of choice in severe pain. However, administering infusions to children requires complex dosage calculations, rate adjustments and often multiple manipulations of injectable medicines to obtain the final "ready to use" solution for both continuous infusion and additional boluses; potentially putting children at high risk.1 2 AIM: To investigate the practice and accuracy of healthcare professionals (HCPs) in hospital theatres and wards in preparing morphine infusions for nurse/patient controlled analgesia (N/PCA) use in a UK children's hospital. METHODS: A mixed methods study in which direct observation of HCPs preparing paediatric morphine infusions for N/PCA in theatres and on wards, focus groups with HCPs and quantitative analysis of morphine concentration in the syringe using UV-Vis Spectrophotometer. The British Pharmacopoeia (BP) reference limits of ±7.5% were used to compare label strength (LS) of morphine infusion with measured concentration. RESULTS: The preparation of 153 syringes was observed which related to 128 paediatric patients [mean age (±sd) 7.5 years±5.6; 65.3% male]. 64% (98/153) were prepared by anaesthetists in theatres, 36% (55/153) by nurses at ward level.Major differences in preparation methods were identified. The final volume prepared was above the required volume (50 mL) in 35.9% (55/153) preparations. Wearing gloves during preparation was not followed in theatre for 83.7% (82/98) of syringes. No decontamination of morphine ampoules was undertaken during preparation of any syringe. Inconsistency in the appropriate syringe size used to withdraw drug from the ampoule was observed in both theatres and wards. Lack of appreciation of the overage in morphine ampoules by HCPs was identified. Of the syringes analysed 61.5% (48/78) had a concentration outside the BP reference limits (92.5-107.5% of LS), most were in excess (83.3%, 40/48). Of these 20.8% (10/48) deviated by more than +20%, with one deviated by 100%. CONCLUSION: This study identified that variation in preparation techniques followed by HCPs may result in morphine N/PCA dosages that are significantly higher or lower than that prescribed. Also, lack of understanding of ampoule overage, accuracy of the syringe size used and the ability to measure small volumes led to inaccurate concentrations in prepared infusions.

Sources and magnitude of error in preparing morphine infusions for nurse-patient controlled analgesia in a UK paediatric hospital.

Background Administering nurse/patient controlled analgesia (N/PCA) to children requires complex dose calculations and multiple manipulations to prepare morphine solutions in 50 mL syringes for administration by continuous infusion with additional boluses. Objective To investigate current practice and accuracy during preparation of morphine N/PCA infusions in hospital theatres and wards at a UK children's hospital. Methods Direct observation of infusion preparation methods and morphine concentration quantification using UV-Vis spectrophotometry. The British Pharmacopoeia specification for morphine sulphate injection drug content (±7.5 %) was used as a reference limit. Results Preparation of 153 morphine infusions for 128 paediatric patients was observed. Differences in preparation method were identified, with selection of inappropriate syringe size noted. Lack of appreciation of the existence of a volume overage (i.e. volume in excess of the nominal volume) in morphine ampoules was identified. Final volume of the infusion was greater than the target (50 mL) in 33.3 % of preparations. Of 78 infusions analysed, 61.5 % had a morphine concentration outside 92.5-107.5 % of label strength. Ten infusions deviated by more than 20 %, with one by 100 %. Conclusions Variation in morphine infusion preparation method was identified. Lack of appreciation of the volume overage in ampoules, volumetric accuracy of different syringe sizes and ability to perform large dilutions of small volumes were sources of inaccuracy in infusion concentration, resulting in patients receiving morphine doses higher or lower than prescribed.

Drug Utilisation Patterns in Children Admitted to a Paediatric General Medical Ward in Five Countries.

OBJECTIVE: To investigate and compare drug prescription patterns in children admitted to a paediatric general medical ward in five countries. METHODS: A prospective cohort study conducted on paediatric medical wards in the UK, Germany, Australia, Hong Kong (HK) and Malaysia. Data were collected over 3 months in each country except in Australia (1 month). All medications prescribed were classified according to the WHO Anatomical Therapeutic Chemical (ATC) classification. For each drug, frequency of prescriptions and patient exposures were calculated for ATC anatomical and therapeutic levels overall and by country. RESULTS: One thousand two hundred and seventy-eight patients were included (Australia 146, Germany 376, UK 313, HK 143 and Malaysia 300); 89.2 % of patients (1140) received medications, median 3 (interquartile range 2-5) drugs per patient. 5367 drugs were prescribed. The most frequently prescribed therapeutic groups in all countries were: systemic antibacterials (1355; 25.2 %), analgesics/non-steroidal anti-inflammatory drugs (NSAIDs) (1173; 21.8 %) and drugs for obstructive airway diseases (472; 8.8 %). Overall, 65.1 % (742) of patients received at least one systemic antibacterial, 63.7 % (726) received one or more analgesic/NSAIDs, and 23.6 % (269) received 'drugs for obstructive airway diseases'. The number of patients exposed to these groups differed significantly between countries (p < 0.05). Paracetamol was the most frequently prescribed in all countries, but metamizole was only used in Germany. Morphine was mainly prescribed in the UK. CONCLUSION: This study provides an overview of drug use patterns in five culturally and ethnically diverse countries. The most frequently used therapeutic groups were similar, but the proportion of patients treated differed between countries. Also within a therapeutic group the specific drug used varied between countries.

Trends and patterns of hormonal contraceptive prescribing for adolescents in primary care in the U.K.

BACKGROUND: Hormonal contraceptives are the most common method used worldwide by teenagers to prevent unwanted pregnancies. To date there are limited data about such use by teenagers in the UK. This study investigated trends and patterns of hormonal contraceptive prescribing to adolescents aged 12-18 years in UK primary care between 2002 and 2011. METHODS: A retrospective cohort study using the IMS Disease Analyzer database was conducted. All females aged 12-18 years with ≥1 prescription for a contraceptive drug between 1 January 2002 and 31 December 2011 were included. Annual prevalence of contraceptive drug prescribing was calculated, and indications for prescribing, and types of contraceptive drug prescribed, were examined. RESULTS: In 2002, 13.7% (6135/44 532) of female adolescents received prescriptions for hormonal contraceptives, compared to 19.0% (6597/34 676) in 2011. The majority of female adolescents [2002: 76.2% (4676/6135); 2011: 65.7% (4334/6597)] received a contraceptive drug for 'contraceptive management'. The combined oral contraceptive (COC), 'progestogen+estrogen', was the most commonly prescribed. Although use of progestogen-only contraceptives was lower than COCs, the number of patients who received desogestrel pills and etonogestrel implants increased during the study period; levonorgestrel pill use declined. Only one injectable progestogen, long-acting depot medroxyprogesterone acetate, was prescribed. CONCLUSIONS: Use of hormonal contraceptives among adolescents increased between 2002 and 2011, and COC usage was dominant. The increasing use of hormonal contraceptives in adolescents, especially in younger adolescents, warrants further investigation, including research into the long-term safety of these medicines in this age group.
