Patterns of initial and first-intensifying antidiabetic drug utilization among patients with type 2 diabetes mellitus in Scotland, 2010-2020: A retrospective population-based cohort study

AIM

To evaluate the utilization and prescribing patterns of antidiabetic drugs (ADDs) for patients with type 2 diabetes mellitus (T2DM) at treatment initiation and first intensification.

METHODS

A retrospective cohort study was performed using linked routinely collected data of patients with T2DM who received ADDs between January 2010 and December 2020 in Scotland. The prescribing patterns were quantified using frequency/percentages, absolute/relative change, and trend tests.

RESULTS

Overall, 145 909 new ADD users were identified, with approximately 91% (N = 132 382) of patients receiving a single ADD at first treatment initiation. Metformin was the most often prescribed monotherapy (N = 118 737, 89.69%). A total of 50 731 patients (39.40%) who were started on metformin (N = 46 730/118 737, 39.36%) or sulphonylurea (SU; N = 4001/10 029, 39.89%) monotherapy had their treatment intensified with one or more additional ADD. Most initial-metformin (45 963/46 730; 98.36%) and initial-SU users (3894/4001; 97.33%) who added further drugs were intensified with single ADDs. SUs (22 197/45 963; 48.29%) were the most common first-intensifying monotherapy after initial metformin use, but these were replaced by sodium-glucose cotransporter-2 (SGLT2) inhibitors in 2019 (SGLT2 inhibitors: 2039/6065, 33.62% vs. SUs: 1924/6065, 31.72%). Metformin was the most frequently added monotherapy to initial SU use (2924/3894, 75.09%). Although the majority of patients received a single ADD, the use of combination therapy significantly increased over time. Nevertheless, there was a significant increasing trend towards prescribing the newer ADD classes (SGLT2 inhibitors, dipeptidyl peptidase-4 inhibitors) as monotherapy or in combination compared with the older ones (SUs, insulin, thiazolidinediones) at both drug initiation and first intensification.

CONCLUSIONS

An overall increasing trend in prescribing the newer ADD classes compared to older ADDs was observed. However, metformin remained the most commonly prescribed first-line ADD, while SGLT2 inhibitors replaced SUs as the most common add-on therapy to initial metformin use in 2019.

Managing infectious diarrhea among young children in community pharmacies in Saudi Arabia and the implications for AMR

Introduction

Diarrhea remains a major global health issue for children under five, contributing substantially to morbidity and mortality. Community pharmacists play a pivotal role in the management of these children; however, their competence in managing childhood diarrhea in Saudi Arabia is under-researched. This is important to ensure optimal patient care.

Method

Simulated patients (SPs) presenting with three pediatric diarrhea scenarios were used to evaluate pharmacists' practice in terms of their counselling, history taking, over-the-counter (OTC) prescribing, medication instructions, diet/fluid advice, and/or information provision. Pharmacists' practice was categorized into adequate, less adequate, and poor.

Results

182 community pharmacists, primarily male and non-Saudi, participated in the study, of which 60% were in chain pharmacies. Only 5% showed adequate practice in currently managing pediatric diarrhea. Of the 182 simulated patient visits, 62% received medication in all three scenarios and 20% were referred to physicians, with 16% of pharmacists failing to provide any form of intervention. The main medications recommended were kaolin (34%), pectin (34%) and metronidazole (11%). While most pharmacists (86%) asked about the patient's identity and age, 15% provided incorrect management information, 16% failed to provide guidance on the prescribed medicines, and 18% dispensed antimicrobials without a valid prescription.

Conclusion

A high level of inadequate management of pediatric diarrhea in Saudi Arabia was observed. This highlights the need for extensive training to improve community pharmacists' practice in service delivery including providing counselling and advice on the appropriate management of childhood diarrhea. The latter is particularly important to reduce antimicrobial resistance.

Quality of ethnicity data within Scottish health records and implications of misclassification for ethnic inequalities in severe COVID-19: a national linked data study

BACKGROUND

We compared the quality of ethnicity coding within the Public Health Scotland Ethnicity Look-up (PHS-EL) dataset, and other National Health Service datasets, with the 2011 Scottish Census.

METHODS

Measures of quality included the level of missingness and misclassification. We examined the impact of misclassification using Cox proportional hazards to compare the risk of severe coronavirus disease (COVID-19) (hospitalization & death) by ethnic group.

RESULTS

Misclassification within PHS-EL was higher for all minority ethnic groups [12.5 to 69.1%] compared with the White Scottish majority [5.1%] and highest in the White Gypsy/Traveller group [69.1%]. Missingness in PHS-EL was highest among the White Other British group [39%] and lowest among the Pakistani group [17%]. PHS-EL data often underestimated severe COVID-19 risk compared with Census data. e.g. in the White Gypsy/Traveller group the Hazard Ratio (HR) was 1.68 [95% Confidence Intervals (CI): 1.03, 2.74] compared with the White Scottish majority using Census ethnicity data and 0.73 [95% CI: 0.10, 5.15] using PHS-EL data; and HR was 2.03 [95% CI: 1.20, 3.44] in the Census for the Bangladeshi group versus 1.45 [95% CI: 0.75, 2.78] in PHS-EL.

CONCLUSIONS

Poor quality ethnicity coding in health records can bias estimates, thereby threatening monitoring and understanding ethnic inequalities in health.

Risk of winter hospitalisation and death from acute respiratory infections in Scotland: national retrospective cohort study

OBJECTIVES

We undertook a national analysis to characterise and identify risk factors for acute respiratory infections (ARIs) resulting in hospitalisation during the winter period in Scotland.

DESIGN

A population-based retrospective cohort analysis.

SETTING

Scotland.

PARTICIPANTS

The study involved 5.4 million residents in Scotland.

MAIN OUTCOME MEASURES

Cox proportional hazard models were used to estimate adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) for the association between risk factors and ARI hospitalisation.

RESULTS

Between 1 September 2022 and 31 January 2023, there were 22,284 (10.9% of 203,549 with any emergency hospitalisation) ARI hospitalisations (1759 in children and 20,525 in adults) in Scotland. Compared with the reference group of children aged 6-17 years, the risk of ARI hospitalisation was higher in children aged 3-5 years (aHR = 4.55; 95% CI: 4.11-5.04). Compared with those aged 25-29 years, the risk of ARI hospitalisation was highest among the oldest adults aged ≥80 years (aHR = 7.86; 95% CI: 7.06-8.76). Adults from more deprived areas (most deprived vs. least deprived, aHR = 1.64; 95% CI: 1.57-1.72), with existing health conditions (≥5 vs. 0 health conditions, aHR = 4.84; 95% CI: 4.53-5.18) or with history of all-cause emergency admissions (≥6 vs. 0 previous emergency admissions, aHR = 7.53; 95% CI: 5.48-10.35) were at a higher risk of ARI hospitalisations. The risk increased by the number of existing health conditions and previous emergency admission. Similar associations were seen in children.

CONCLUSIONS

Younger children, older adults, those from more deprived backgrounds and individuals with greater numbers of pre-existing conditions and previous emergency admission were at increased risk for winter hospitalisations for ARI.

Antimicrobial stewardship capacity and antibiotic utilisation practices in the Cape Coast Teaching Hospital, Ghana: A point prevalence survey study

INTRODUCTION

Antimicrobial resistance (AMR) is a global threat that necessitates coordinated strategies to improve antibiotic prescribing and reduce AMR. A key activity is ascertaining current prescribing patterns in hospitals to identify targets for quality improvement programmes.

METHODS

The World Health Organisation point prevalence survey methodology was used to assess antibiotic prescribing in the Cape Coast Teaching Hospital. All core variables identified by the methodology were recorded.

RESULTS

A total of 78.8% (82/104) patients were prescribed at least one antibiotic, with the majority from adult surgical wards (52.14%). Significantly longer hospital stays were associated with patients who underwent surgery (p = 0.0423). "Access" antibiotics dominated total prescriptions (63.8%, 132/207) with ceftriaxone, cefuroxime, and ciprofloxacin being the most prescribed "Watch" antibiotics. The most common indications were for medical prophylaxis (59.8%, 49/82) and surgical prophylaxis (46.3%, 38/82). Over one-third of surgical prophylaxis (34.2%, 13/38) indications extended beyond one day. There was moderate documentation of reasons for antibiotic treatment in patient notes (65.9%, 54/82), and targeted therapy after samples were taken for antimicrobial susceptibility testing (41.7%, 10/24). Guideline compliance was low (25%) where available.

CONCLUSIONS

There was high use of antibiotics within the hospital which needs addressing. Identified quality targets include developing surgical prophylaxis guidelines, reviewing "Watch" antibiotic prescribing, and assessing antibiotic durations for patients on two or more antibiotics. Organizational-level deficiencies were also identified that need addressing to help instigate ASPs. These can be addressed by developing local prescribing protocols and antibiotic stewardship policies in this hospital and wider in Ghana and across Africa.

Involving Patients and Clinicians in the Design of Wireframes for Cancer Medicines Electronic Patient Reported Outcome Measures in Clinical Care: Mixed Methods Study

BACKGROUND

Cancer treatment is a key component of health care systems, and the increasing number of cancer medicines is expanding the treatment landscape. However, evidence of the impact on patients has been focused more on chemotherapy toxicity and symptom control and less on the effect of cancer medicines more broadly on patients' lives. Evolving electronic patient-reported outcome measures (ePROMs) presents the opportunity to secure early engagement of patients and clinicians in shaping the collection of quality-of-life metrics and presenting these data to better support the patient-clinician decision-making process.

OBJECTIVE

The aim of this study was to obtain initial feedback from patients and clinicians on the wireframes of a digital solution (patient app and clinician dashboard) for the collection and use of cancer medicines ePROMs.

METHODS

We adopted a 2-stage, mixed methods approach. Stage 1 (March to June 2019) consisted of interviews and focus groups with cancer clinicians and patients with cancer to explore the face validity of the wireframes, informed by the technology acceptance model constructs (perceived ease of use, perceived usefulness, and behavioral intention to use). In stage 2 (October 2019 to February 2020), the revised wireframes were assessed through web-based, adapted technology acceptance model questionnaires. Qualitative data (stage 1) underwent a framework analysis, and descriptive statistics were performed on quantitative data (stage 2). Clinicians and patients with cancer were recruited from NHS Greater Glasgow & Clyde, the largest health board in Scotland.

RESULTS

A total of 14 clinicians and 19 patients participated in a combination of stage 1 interviews and focus groups. Clinicians and patients indicated that the wireframes of a patient app and clinician dashboard for the collection of cancer medicines ePROMs would be easy to use and could focus discussions, and they would be receptive to using such tools in the future. In stage 1, clinicians raised the potential impact on workload, and both groups identified the need for adequate IT skills to use each technology. Changes to the wireframes were made, and in stage 2, clinicians (n=8) and patients (n=16) indicated it was "quite likely" that the technologies would be easy to use and they would be "quite likely" to use them in the future. Notably, clinicians indicated that they would use the dashboard to enable treatment decisions "with around half" of their patients.

CONCLUSIONS

This study emphasizes the importance of consulting both patients and clinicians in the design of digital solutions. The wireframes were perceived positively by patients and clinicians who were willing to use such technologies if available in the future as part of routine care. However, challenges were raised, and some differences were identified between participant groups, which warrant further research.

Estimated indirect costs of haemodialysis versus peritoneal dialysis from a patients' perspective at an Academic Hospital in Pretoria, South Africa

In South Africa (SA), patients with kidney failure can be on either haemodialysis (HD), which is performed by a healthcare professional in a hospital thrice weekly; or peritoneal dialysis (PD), which can performed daily at home. There needs to be more studies within the South African healthcare sector on the cost of kidney failure and especially the indirect costs associated with patients being on dialysis to provide future guidance. This study aimed to determine and compare the indirect costs associated with HD and PD from the patients' perspective at an Academic Hospital in Pretoria. The study used a cross-sectional prospective quantitative study design. The researcher used face-to-face interviews to collect data and the human capital approach to calculate productivity losses. The study population included all patients over 18 receiving HD or PD for over three months; 54 patients participated (28 on HD and 26 on PD). The study lasted seven months, from September 2020 to March 2021. Haemodialysis patients incurred greater productivity losses per annum ($8127.55) compared to PD (R$3365.34); the difference was statistically significant with a P-value of p < 0.001. More HD (96.4%) patients were unemployed than (76.9%) PD patients.

Data Resource Profile: The Hospital Electronic Prescribing and Medicines Administration (HEPMA) National Data Collection in Scotland

Introduction

To support both electronic prescribing and documentation of medicines administration in secondary care, hospitals in Scotland are currently implementing the Hospital Electronic Prescribing and Medicines Administration (HEPMA) software. Driven by the COVID-19 pandemic, agreements have been put in place to centrally collate data stemming from the operational HEPMA system. The aim was to develop a national data resource based on records created in secondary care, in line with pre-existing collections of data from primary care.

Methods

HEPMA is a live clinical system and updated on a continuous basis. Data is automatically extracted from local systems at least weekly and, in most cases, on a nightly basis, and integrated into the national HEPMA dataset. Subsequently, the data are subject to quality checks including data consistency and completeness. Records contain a unique patient identified (Community Health Index number), enabling linkage to other routinely collected data including primary care prescriptions, hospital admission episodes, and death records.

Results

The HEPMA data resource captures and compiles information on all medicines prescribed within the ward/hospital covered by the system; this includes medicine name, formulation, strength, dose, route, and frequency of administration, and dates and times of prescribing. In addition, the HEPMA dataset also captures information on medicines administration, including dates and time of administration. Data is available from January 2019 onwards and held by Public Health Scotland.

Conclusion

The national HEPMA data resource supports cross-sectional/point-prevalence studies including drug utilisation studies, and also offers scope to conduct longitudinal studies, e.g., cohort and case-control studies. With the possibility to link to other relevant datasets, additional areas of interest may include health policy evaluations and health economics studies. Access to data is subject to approval; researchers need to contact the electronic Data Research and Innovation Service (eDRIS) in the first instance.

Ethnic inequalities in positive SARS-CoV-2 tests, infection prognosis, COVID-19 hospitalisations and deaths: analysis of 2 years of a record linked national cohort study in Scotland

BACKGROUND

This study aims to estimate ethnic inequalities in risk for positive SARS-CoV-2 tests, COVID-19 hospitalisations and deaths over time in Scotland.

METHODS

We conducted a population-based cohort study where the 2011 Scottish Census was linked to health records. We included all individuals ≥ 16 years living in Scotland on 1 March 2020. The study period was from 1 March 2020 to 17 April 2022. Self-reported ethnic group was taken from the census and Cox proportional hazard models estimated HRs for positive SARS-CoV-2 tests, hospitalisations and deaths, adjusted for age, sex and health board. We also conducted separate analyses for each of the four waves of COVID-19 to assess changes in risk over time.

FINDINGS

Of the 4 358 339 individuals analysed, 1 093 234 positive SARS-CoV-2 tests, 37 437 hospitalisations and 14 158 deaths occurred. The risk of COVID-19 hospitalisation or death among ethnic minority groups was often higher for White Gypsy/Traveller (HR 2.21, 95% CI (1.61 to 3.06)) and Pakistani 2.09 (1.90 to 2.29) groups compared with the white Scottish group. The risk of COVID-19 hospitalisation or death following confirmed positive SARS-CoV-2 test was particularly higher for White Gypsy/Traveller 2.55 (1.81-3.58), Pakistani 1.75 (1.59-1.73) and African 1.61 (1.28-2.03) individuals relative to white Scottish individuals. However, the risk of COVID-19-related death following hospitalisation did not differ. The risk of COVID-19 outcomes for ethnic minority groups was higher in the first three waves compared with the fourth wave.

INTERPRETATION

Most ethnic minority groups were at increased risk of adverse COVID-19 outcomes in Scotland, especially White Gypsy/Traveller and Pakistani groups. Ethnic inequalities persisted following community infection but not following hospitalisation, suggesting differences in hospital treatment did not substantially contribute to ethnic inequalities.

Assessment of the quality of antimicrobial prescribing among hospitalized patients in a teaching hospital in Ghana: findings and implications

OBJECTIVE

There is a need to assess the quality of antimicrobial prescribing in hospitals as a first step toward improving future prescribing to reduce antimicrobial resistance (AMR). This is in line with Ghana's National Action Plan.

METHODS

A point prevalence survey of antimicrobial use was undertaken at the adult medical, surgical, and pediatric wards of Tamale Teaching Hospital using the standardized Global Point Prevalence Survey (GPPS) tool. Key target areas include adherence to current guidelines, limiting the prescribing of 'Watch' antibiotics with their greater resistance potential, and limiting the prescribing of antibiotics post-operatively to prevent surgical site infections (SSIs).

RESULTS

Out of 217 patients' medical records assessed, 155 (71.4%) patients were prescribed antimicrobials. The rates were similar among children (73.9%) and adults (70.3%). Most of the antibiotics prescribed were in the WHO 'Watch' group (71.0%) followed by those in the 'Access' group (29%). Out of the 23 cases indicated for surgical antimicrobial prophylaxis to prevent SSIs, the majority (69.6%) were given doses for more than 1 day, with none receiving a single dose. This needs addressing to reduce AMR and costs. Guideline compliance with the current Ghanaian Standard Treatment Guidelines (GSTG) for managing infections was also low (28.7%). The type of indication was the only independent predictor of guideline compliance (aOR = 0.013 CI 0.001-0.127, p-value = 0.001).

CONCLUSION

Given current concerns with antimicrobial prescribing in this hospital, deliberate efforts must be made to improve the appropriateness of prescribing to reduce AMR via targeted antimicrobial stewardship programs.

Understanding and reporting odds ratios as rate-ratio estimates in case-control studies

Background

We noted that there remains some confusion in the health-science literature on reporting sample odds ratios as estimated rate ratios in case-control studies.

Methods

We recap historical literature that definitively answered the question of when sample odds ratios (ORs) from a case-control study are consistent estimators for population rate ratios. We use numerical examples to illustrate the magnitude of the disparity between sample ORs in a case-control study and population rate ratios when sufficient conditions for them to be equal are not satisfied.

Results

We stress that in a case-control study, sampling controls from those still at risk at the time of outcome event of the index case is not sufficient for a sample OR to be a consistent estimator for an intelligible rate ratio. In such studies, constancy of the exposure prevalence together with constancy of the hazard ratio (HR) (i.e., the instantaneous rate ratio) over time is sufficient for this result if sampling time is not controlled; if time is controlled, constancy of the HR will suffice. We present numerical examples to illustrate how failure to satisfy these conditions adds a small systematic error to sample ORs as estimates of population rate ratios.

Conclusions

We recommend that researchers understand and critically evaluate all conditions used to interpret their estimates as consistent for a population parameter in case-control studies.

Airport-based pharmacies: Products, services and challenges essential for patients in a global travel landscape

The role of airport pharmacies has grown in recent years to provide a range of services to travelers, including over-the-counter and prescription medicines, as well as advice on prevention of infectious and other diseases. Prevention, including protective equipment, is especially important during pandemics, as seen with the recent coronavirus disease-2019 (COVID-19) pandemic. In addition, offering vaccinations where appropriate. However, this is not universal, and there are currently no acknowledged guidelines for pharmacists operating within airports. In addition, research into their role as well as potential ways to improve this is lacking. This is a concern with community pharmacists playing a valuable role during the COVID-19 pandemic. Potential ways forward include greater research into their activities to enhance their role and address challenges. These include issues of brand names and language, as well as encouraging travel pharmacy in future university curricula. In addition, producing guidelines for their activities and monitoring their implementation. This can help build a greater role for their services, benefiting airport staff and travelers in the future.

Meta-analysis of factors associated with antidiabetic drug prescribing for type 2 diabetes mellitus

BACKGROUND

There is a lack of consensus on prescribing alternatives to initial metformin therapy and intensification therapy for type 2 diabetes mellitus (T2DM) management. This review aimed to identify/quantify factors associated with prescribing of specific antidiabetic drug classes for T2DM.

METHODS

Five databases (Medline/PubMed, Embase, Scopus, Web of Science) were searched using the synonyms of each concept (patients with T2DM, antidiabetic drugs and factors influencing prescribing) in both free text and Medical Subject Heading (MeSH) forms. Quantitative observational studies evaluating factors associated with antidiabetic prescribing of metformin, sulfonylurea, thiazolidinedione, Dipeptidyl-peptidase 4 inhibitors (DPP4-I), sodium glucose transporter 2 inhibitors (SGLT2-I), Glucagon-Like peptide receptor agonist (GLP1-RA) and insulin in outpatient settings and published from January 2009 to January 2021 were included. Quality assessment was performed using a Newcastle-Ottawa scale. The validation was done for 20% of identified studies. The pooled estimate was measured using a three-level random-effect meta-analysis model based on odds ratio [95% confidence interval]. Age, sex, body mass index (BMI), glycaemic control (HbA1c) and kidney-related problems were quantified.

RESULTS

Of 2331 identified studies, 40 met the selection criteria. Of which, 36 and 31 studies included sex and age, respectively, while 20 studies examined baseline BMI, HbA1c and kidney-related problems. The majority of studies (77.5%, 31/40) were rated as good and despite that the overall heterogeneity for each studied factor was more than 75%, it is mostly related to within-study variance. Older age was significantly associated with higher sulfonylurea prescription (1.51 [1.29-1.76]), yet lower prescribing of metformin (0.70 [0.60-0.82]), SGLT2-I (0.57 [0.42-0.79]) and GLP1-RA (0.52 [0.40-0.69]); while higher baseline BMI showed opposite significant results (sulfonylurea: 0.76 [0.62-0.93], metformin: 1.22 [1.08-1.37], SGLT2-I: 1.88 [1.33-2.68], and GLP1-RA: 2.35 [1.54-3.59]). Both higher baseline HbA1c and having kidney-related problems were significantly associated with lower metformin prescription (0.74 [0.57-0.97], 0.39 [0.25-0.61]), but more insulin prescriptions (2.41 [1.87-3.10], 1.52 [1.10-2.10]). Also, DPP4-I prescriptions were higher for patients with kidney-related problems (1.37 [1.06-1.79]) yet lower among patients with higher HbA1c (0.82 [0.68-0.99]). Sex was significantly associated with GLP1-RA and thiazolidinedione prescribing (F:M; 1.38 [1.19-1.60] and 0.91 [0.84-0.98]).

CONCLUSION

Several factors were identified as potential determinants of antidiabetic drug prescribing. The magnitude and significance of each factor differed by antidiabetic class. Patient's age and baseline BMI had the most significant association with the choice of four out of the seven studied antidiabetic drugs followed by the baseline HbA1c and kidney-related problems which had an impact on three studied antidiabetic drugs, whereas sex had the least impact on prescribing decision as it was associated with GLP1-RA and thiazolidinedione only.

Current rates of purchasing of antibiotics without a prescription across sub-Saharan Africa; rationale and potential programmes to reduce inappropriate dispensing and resistance

INTRODUCTION

Antimicrobial resistance (AMR) is a global concern. Currently, the greatest mortality due to AMR is in Africa. A key driver continues to be high levels of dispensing of antibiotics without a prescription.

AREAS COVERED

A need to document current rates of dispensing, their rationale and potential ways forward including antimicrobial stewardship programmes (ASPs). A narrative review was undertaken. The highest rates of antibiotic purchasing were in Eritrea (up to 89.2% of antibiotics dispensed), Ethiopia (up to 87.9%), Nigeria (up to 86.5%), Tanzania (up to 92.3%) and Zambia (up to 100% of pharmacies dispensing antibiotics without a prescription). However, considerable variation was seen with no dispensing in a minority of countries and situations. Key drivers of self-purchasing included high co-payment levels for physician consultations and antibiotic costs, travel costs, convenience of pharmacies, patient requests, limited knowledge of antibiotics and AMR and weak enforcement. ASPs have been introduced in some African countries along with quality targets to reduce inappropriate dispensing, centering on educating pharmacists and patients.

EXPERT OPINION

ASP activities need accelerating among community pharmacies alongside quality targets, with greater monitoring of pharmacists' activities to reduce inappropriate dispensing. Such activities, alongside educating patients and healthcare professionals, should enhance appropriate dispensing of antibiotics and reduce AMR.

Selling antibiotics without prescriptions among community pharmacies and drug outlets: a simulated client study from Ghana

BACKGROUND

Selling antibiotics without prescriptions is mostly illegal worldwide, including in Ghana, and promotes antimicrobial resistance. We evaluated the prevalence and practice of selling antibiotics without prescriptions among community pharmacies (CPs) and drug outlets, for the first time, in Ghana to quantify and characterize this issue to inform future interventions.

RESEARCH DESIGN AND METHODS

Two scenarios utilizing the Simulated Client Methodology were enacted: an upper respiratory tract infection of viral origin (scenario one); and pediatric diarrhea (scenario two). CPs/Outlets were selected by stratified proportional random sampling from four metropolitan cities (~14% of the total Ghanaian population). Selling of antibiotics was assessed at three demand levels and its overall prevalence was estimated, then stratified by the study variables.

RESULTS

Out of the 265 sampled CPs/outlets, the prevalence of selling antibiotic without prescription was 88.3% (n = 234/265), with variations not only across the four regions [92.5% (n = 123/133) in Kumasi, 87.5% (n = 14/16) in Cape Coast, 84.1% (n = 69/82) in Accra, and 82.4% (n = 28/34) in Tamale] but also across CPs [90% (n = 121/134)] and drug outlets [86% (n = 113/131)].

CONCLUSIONS

A very high prevalence/sub-optimal practice of selling antibiotics without prescriptions was found. This highlights the need to increase compliance with antibiotic dispensing legislation through evidence-based interventions including education of key stakeholders.

Trends in the Cost of Medicines, Consultation Fees and Clinic Visits in Malaysia's Private Primary Healthcare System: Employer Health Insurance Coverage

Objective

To examine trends in the cost of medicines, consultation fees and clinic visits among the employees covered by the employer health insurance in Malaysia's private primary healthcare system in Malaysia.

Designs

Retrospective cross-sectional study.

Setting

PMCare claims database from January 2016 to August 2019.

Participants

A total of 83,556 outpatient clinic visits involving 10,150 IIUM employees of the International Islamic University Malaysia (IIUM) to private general practitioners (GPs). During the study period, IIUM adopts the incentive structure of capping coverage at Ringgit Malaysia (RM) 45/outpatient visit (USD 10.58) to cover for consultation fees and medicine costs.

Main Outcome Measures

The monthly percentage change in the number of clinic visits, medicine costs, consultation fees and total costs between January 2016 and August 2019. A simple linear regression using Stata v15.1 was also performed to measure the association between the characteristics of the prescribed medicines and medicine charges.

Results

The number of clinic visits per patient increased by 17% from January 2016 to August 2019, with consultation fees increasing by 113.9% and total costs by 7.9% per clinic visit per patient. Conversely, the cost of medicines and the number of medicines prescribed per clinic visit per patient decreased by 39.7% and 6.3%, respectively.

Conclusion

Within the incentive structure of capping the total amount of coverage per clinic visit, medicine costs were reduced by decreasing the number of medicines prescribed, to offset the increased consultation fees. This may create perverse incentives that affect medicine use with negative consequences for the health system and health insurers.

Evaluation of duration of antibiotic therapy across hospitals in Scotland including the impact of COVID-19 pandemic: a segmented interrupted time series analysis

BACKGROUND

Little is known about the duration of antibiotic use in hospital settings. We evaluated the duration of hospital antibiotic therapy for four commonly prescribed antibiotics (amoxicillin, co-amoxiclav, doxycycline, and flucloxacillin) including the assessment of COVID-19 impact.

METHODS

A repeated, cross-sectional study using the Hospital Electronic Prescribing and Medicines Administration system (January/2019-March/2022). Monthly median duration of therapy/duration categories was calculated, stratified by routes of administration, age, and sex. The impact of COVID-19 was assessed using segmented time-series analysis.

RESULTS

There were significant variations in the median duration of therapy across routes of administration (P < 0.05), with the highest value among those antibiotic courses composed of both oral and IV antibiotics ('Both' group). Significantly higher proportions of prescriptions within the 'Both' group had a duration of >7 days compared to oral or IV. The duration of therapy differed significantly by age. Some small statistically significant changes in the level/trends of duration of therapy were observed in the post-COVID-19 period.

CONCLUSIONS

No evidence for prolonged duration of therapy were observed, even during COVID-19 pandemic. The duration of IV therapy was relatively short, suggesting timely clinical review and consideration of IV to oral switch. Longer duration of therapy was observed among older patients.

Perceptions of and Preparedness for the Application of Pharmacoeconomics in Practice, among Final Year Bachelor of Pharmacy Students in South Africa: A National Cross-Sectional Study

For the improvement of access to health, many countries including South Africa, have adopted universal healthcare. However, this requires skills to apply health technology assessments for the facilitation of investment decisions. This study aimed to ascertain final year Bachelor of Pharmacy (BPharm) students' perceptions of the relevance of pharmacoeconomics in pharmacy practice, and their level of preparedness to apply pharmacoeconomic principles, using a quantitative, cross-sectional, and descriptive design. Data were collected using a self-administered questionnaire over 12 months, and included student demographics, knowledge about pharmacoeconomics and its applicability in practice, as well as students' satisfaction with the appropriateness of the curriculum content. Five of nine universities offering pharmacy education took part. The overallstudent response rate was 38.1% (189/496), with 26.2% (45/172) of students signifying a good understanding of basic pharmacoeconomic concepts. Pharmacoeconomics application in South Africa was perceived to be relevant by 87.5% (140/160); however, 47.0% (79/168) felt they were not prepared to apply pharmacoeconomic principles in medicine management, and 86.7% (137/158) wanted to acquire additional pharmacoeconomic knowledge. Whilst students' perceptions of the relevance of pharmacoeconomics were positive, results indicated a gap in knowledge, understanding, and application. Addressing this gap may increase students' preparedness to apply pharmacoeconomic principles and better equip them for the practical application of pharmacoeconomics post qualification. Consequently, we have started this process.

Risk Awareness and Demographic Characteristics Associated With the Use of Sexual Enhancement Supplements Among University Staff: A Cross-Sectional Study in the United Arab Emirates

Sexual enhancement supplements (SESs) that have illegal additions of pharmaceuticals or analogues pose a significant health risk, particularly with long-term usage. When supplements are adulterated with phosphodiesterase type 5 (PDE-5) inhibitors, dosages can vary widely and there may be an increase in adverse effects and drug-drug interactions which cannot be avoided. Consequently, there is a need to evaluate the public risk awareness toward SES and the associated adverse events as well as explore significant factors associated with knowledge and risk awareness. A cross-sectional community-based study was conducted among University male students and staff at Ajman University, United Arab Emirates (UAE), using a self-administered survey via a web-based electronic link to explore key issues. A total of 1,101 male subjects participated in the study and completed the questionnaire. Four hundred and thirty-three(39.3%) (95% confidence interval [CI]: 33.2-44.5) participants reported using SES products. Of these, 137 (31.6%) [95% CI: 28.6-37.2] experienced adverse effects from SES product use. SES use was more prevalent among participants aged 60 to 69 years (odds ratio [OR]: 2.94; 95% CI: 1.63-5.28), diabetic patients (OR: 2.61; 95% CI: 1.75-3.90), hypertension patients (OR: 2.12; 95% CI: 1.45-3.1), and those overweight or obese (OR: 1.84; 95% CI: 1.44-2.35). This study indicates that SES is a popular practice among the UAE university staff and students. However, there is a need to implement risk awareness programs to raise public awareness regarding SES use and safety. Regulatory bodies are encouraged to provide additional advice on the proper use and possible risks of consuming SES.

Real-world effectiveness of systemic anticancer therapy for advanced melanoma in the west of Scotland from 2010 to 2018

Aim: Assess the real-world effectiveness of systemic anticancer therapy in advanced (unresectable or metastatic) melanoma. Methods: This was a retrospective cohort study linking routine healthcare data with systemic anticancer therapy prescriptions for patients starting immunotherapy or targeted treatments between 1 November 2010 and 31 December 2017 in the west of Scotland. Results: Among 362 patients identified, median overall survival varied between 18.5 months (95% CI: 14.4-not estimable) for ipilimumab/nivolumab combination and 5.6 months (95% CI: 4.5-7.3) for dabrafenib, but there were differences in the characteristics of each regimen cohort. Raised lactate dehydrogenase levels and Eastern Cooperative Oncology Group performance status ≥2 negatively impacted overall survival. Conclusion: The patients had a shorter median overall survival than those in pivotal trials. This was expected, given that this real-world cohort included patients with poorer prognostic indicators, typically excluded from trials.

An umbrella review and meta-analysis of renin-angiotensin system drugs use and COVID-19 outcomes

BACKGROUND

Despite the availability of extensive literature on the effect of angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin-receptor blockers (ARBs) on COVID-19 outcomes, the evidence is still controversial. We aimed to provide a comprehensive assessment of the effect of ACEIs/ARBs on COVID-19-related outcomes by summarising the currently available evidence.

METHODS

An umbrella review was conducted using Medline (OVID), Embase, Scopus, Cochrane library and medRxiv from inception to 1 February 2021. Systematic reviews with meta-analysis that evaluated the effect of ACEIs/ARBs on COVID-19-related clinical outcomes were eligible. Studies' quality was appraised using the AMSTAR 2 Critical Appraisal Tool. Data were analysed using the random-effects modelling including several subgroup analyses. Heterogenicity was assessed using I² statistic. The study protocol was registered in PROSPERO (CRD42021233398) and reported using PRISMA guidelines.

RESULTS

Overall, 47 reviews were eligible for inclusion. Out of the nine COVID-19 outcomes evaluated, there was significant associations between ACEIs/ARBs use and each of death (OR = 0.80, 95%CI = 0.75-0.86; I²  = 51.9%), death/ICU admission as composite outcome (OR = 0.86, 95%CI = 0.80-0.92; I²  = 43.9%), severe COVID-19 (OR = 0.86, 95%CI = 0.78-0.95; I²  = 68%) and hospitalisation (OR = 1.23, 95%CI = 1.04-1.46; I²  = 76.4%). The significant reduction in death/ICU admission, however, was higher among studies which presented adjusted measure of effects (OR = 0.63, 95%CI = 0.47-0.84) and were of moderate quality (OR = 0.74, 95%CI = 0.63-0.85).

CONCLUSIONS

Collective evidence from observational studies indicate a good quality evidence on the significant association between ACEIs/ARBs use and reduction in death and death/ICU admission, but poor-quality evidence on both reducing severe COVID-19 and increasing hospitalisation. Our findings further support the current recommendations of not discontinuing ACEIs/ARBs therapy in patients with COVID-19.

The impact of the COVID-19 pandemic on cardiovascular disease prevention and management

How the Coronavirus Disease 2019 (COVID-19) pandemic has affected prevention and management of cardiovascular disease (CVD) is not fully understood. In this study, we used medication data as a proxy for CVD management using routinely collected, de-identified, individual-level data comprising 1.32 billion records of community-dispensed CVD medications from England, Scotland and Wales between April 2018 and July 2021. Here we describe monthly counts of prevalent and incident medications dispensed, as well as percentage changes compared to the previous year, for several CVD-related indications, focusing on hypertension, hypercholesterolemia and diabetes. We observed a decline in the dispensing of antihypertensive medications between March 2020 and July 2021, with 491,306 fewer individuals initiating treatment than expected. This decline was predicted to result in 13,662 additional CVD events, including 2,281 cases of myocardial infarction and 3,474 cases of stroke, should individuals remain untreated over their lifecourse. Incident use of lipid-lowering medications decreased by 16,744 patients per month during the first half of 2021 as compared to 2019. By contrast, incident use of medications to treat type 2 diabetes mellitus, other than insulin, increased by approximately 623 patients per month for the same time period. In light of these results, methods to identify and treat individuals who have missed treatment for CVD risk factors and remain undiagnosed are urgently required to avoid large numbers of excess future CVD events, an indirect impact of the COVID-19 pandemic.

Prevalence of Psychological Disorders among Health Workers During the COVID-19 Pandemic: A Systematic Review and Meta-Analysis

Background

Repeated contact with patients with COVID-19 and working in quarantine conditions has made health workers vulnerable to psychological distress during the COVID-19 pandemic. The goal of the present systematic review and meta-analysis was to examine the prevalence of the various psychological distresses among health workers during the COVID-19 pandemic.

Methods

PubMed, Scopus, Web of Science, EMBASE, and Cochrane databases were searched for access to papers examining psychological distress among healthcare workers during the COVID-19 pandemic. Risk of bias was assessed using the Newcastle-Ottawa Scale (NOS). Heterogeneity among the studies was examined using the Cochran's Q test; because heterogeneity was significant, the random effects model was used to examine the prevalence of psychological distress.

Results

Overall, 12 studies with a total sample size of 5265 were eligible and included in the analysis. Prevalence rates of depression, anxiety, and PTSD were 20% (95% CI: 14-27), 23% (95% CI: 18-27), and 8% (95% CI: 6-9), respectively. The highest prevalence rates of depression and anxiety were related to the SDS and the GAD-7, respectively, and the lowest prevalence rates of the two aforementioned variables were related to the DASS-21.

Conclusions

The high prevalence of psychological distress among healthcare workers during the COVID-19 epidemic can have negative effects on their health and the quality of services provided. Therefore, training coping strategies for psychological distress in this pandemic seems necessary.

Assessing medication use patterns in patients hospitalised with COVID-19: a retrospective study

OBJECTIVE

To describe patterns of medication use-that is, dexamethasone; remdesivir; and tocilizumab-in the management of patients hospitalised with COVID-19.

DESIGN AND SETTING

Retrospective observational study, using routinely collected, linked electronic data from clinical practice in Scotland. Data on drug exposure in secondary care has been obtained from the Hospital Electronic Prescribing and Medicines Administration System.

PARTICIPANTS

Patients being treated with the drugs of interest and hospitalised for COVID-19 between 1 March 2020 and 10 November 2021.

OUTCOMES

Identification of patients subject to the treatments of interest; summary of patients' baseline characteristics; description of medication use patterns and treatment episodes. Analyses were descriptive in nature.

RESULTS

Overall, 4063 patients matching the inclusion criteria were identified in Scotland, with a median (IQR) age of 64 years (52-76). Among all patients, 81.4% (n=3307) and 17.8% (n=725) were treated with one or two medicines, respectively; dexamethasone monotherapy accounted for the majority (n=3094, 76.2%) followed by dexamethasone in combination with tocilizumab (n=530, 13.0%). Treatment patterns were variable over time but roughly followed the waves of COVID-19 infections; however, the different drugs were used to varying degrees during the study period.The median (IQR) treatment duration differed by medicine: dexamethasone 5 days (2-9); remdesivir 5 days (2-5); and tocilizumab 1 day (1-1). The overall median (IQR) length of hospital stay among all patients included in the study cohort was 9 days (5-17); 24.7% of patients died in hospital.

CONCLUSION

The use of adjuvant medicines in patients hospitalised with COVID-19 appears in line with evolving evidence and changing treatment guidelines. In-hospital electronic prescribing systems are a valuable source of information, providing detailed patient-level data on in-hospital drug use.

Effects of the COVID-19 pandemic on secondary care for cardiovascular disease in the UK: an electronic health record analysis across three countries

BACKGROUND

Although morbidity and mortality from COVID-19 have been widely reported, the indirect effects of the pandemic beyond 2020 on other major diseases and health service activity have not been well described.

METHODS

Analyses used national administrative electronic hospital records in England, Scotland and Wales for 2016-2021. Admissions and procedures during the pandemic (2020-2021) related to six major cardiovascular conditions (acute coronary syndrome, heart failure, stroke/transient ischaemic attack, peripheral arterial disease, aortic aneurysm, and venous thromboembolism) were compared to the annual average in the pre-pandemic period (2016-2019). Differences were assessed by time period and urgency of care.

RESULTS

In 2020, there were 31 064 (-6%) fewer hospital admissions (14 506 [-4%] fewer emergencies, 16 560 [-23%] fewer elective admissions) compared to 2016-2019 for the six major cardiovascular diseases combined. The proportional reduction in admissions was similar in all three countries. Overall, hospital admissions returned to pre-pandemic levels in 2021. Elective admissions remained substantially below expected levels for almost all conditions in all three countries (-10 996 [-15%] fewer admissions). However, these reductions were offset by higher than expected total emergency admissions (+25 878 [+6%] higher admissions), notably for heart failure and stroke in England, and for venous thromboembolism in all three countries. Analyses for procedures showed similar temporal variations to admissions.

CONCLUSION

This study highlights increasing emergency cardiovascular admissions during the pandemic, in the context of a substantial and sustained reduction in elective admissions and procedures. This is likely to increase further the demands on cardiovascular services over the coming years.

Appropriateness of surgical antimicrobial prophylaxis in a teaching hospital in Ghana: findings and implications

Background

Surgical site infections (SSIs) are among the most common infections seen in hospitalized patients in low- and middle-income countries (LMICs), accounting for up to 60% of hospital-acquired infections. Surgical antimicrobial prophylaxis (SAP) has shown to be an effective intervention for reducing SSIs and their impact. There are concerns of inappropriate use of SAP in Ghana and therefore our audit in this teaching hospital.

Methods

A retrospective cross sectional clinical audit of medical records of patients undergoing surgery over a 5 month duration from January to May 2021 in Ho Teaching Hospital. A data collection form was designed to collect key information including the age and gender of patients, type and duration of surgery, choice and duration of SAP. The collected data was assessed for the proportion of SAP compliance with Ghana Standard Treatment Guidelines (STGs) and any association with various patient, surgical wound and drug characteristics.

Results

Of the 597 medical records assessed, the mean age of patients was 35.6 ± 12.2 years with 86.8% (n = 518) female. Overall SAP compliance with the STG was 2.5% (n = 15). SAP compliance due to appropriate choice of antimicrobials was 67.0% (n = 400) and duration at 8.7% (n = 52). SAP compliance was predicted by duration of SAP (P < 0.000) and postoperative hospitalization duration (P = 0.005).

Conclusions

SAP compliance rate was suboptimal, principally due to a longer duration of prescription. Quality improvement measures such as education of front-line staff on guideline compliance, coupled with clinical audit and regular updates, are urgently needed to combat inappropriate prescribing and rising resistance rates.

A national, multicentre web-based point prevalence survey of antimicrobial use in community healthcare centres across South Africa and the implications

OBJECTIVE

Up to 90% of antimicrobials globally are prescribed and dispensed in ambulatory care. However, there are considerable gaps regarding the extent and rationale for their use especially in low- and middle-income countries such as South Africa. Point prevalent surveys (PPS) are useful to determine current prescribing patterns, identify targets for quality improvement and evaluate the effectiveness of antimicrobial stewardship programmes (ASPs) within institutions. Consequently, the objective of this study was to undertake a PPS within community healthcare centers (CHCs) in South Africa given their importance to the public healthcare system. The findings will be used to provide guidance on future interventions to improve antimicrobial use in South Africa and wider.

METHODS

A PPS of antimicrobial consumption was undertaken among patients attending 18 CHCs in South Africa. A web-based application was used to record the utilization data, with utilization assessed against World Health Organization (WHO) and South African guidelines.

RESULTS

The overall prevalence of antimicrobial use amongst patients attending the CHCs was 21.5% (420 of 1958 patients). This included one or more antimicrobials per patient. The most frequently prescribed antimicrobials were amoxicillin (32.9%), isoniazide (11.3%) and a combination of rifampicin, isoniazid, pyrazinamide and ethambutol (Rifafour®) (10.5%), with the majority from the WHO Access list of antibiotics. There was high adherence to guidelines (93.4%). The most common indication for antibiotics were ear, nose and throat infections (22.8%), with no culture results recorded in patients' files.

CONCLUSIONS

It's encouraging to see high adherence to South African guidelines when antimicrobials were prescribed, with the majority taken from the WHO Access list. However, there were concerns with appreciable prescribing of antimicrobials for upper respiratory tract infections that are essentially viral in origin, and a lack of microbiological testing. The establishment of ASPs can help address identified concerns through designing and implementing appropriate interventions.

Prevalence of bacterial coinfection and patterns of antibiotics prescribing in patients with COVID-19: A systematic review and meta-analysis

Background

Evidence around prevalence of bacterial coinfection and pattern of antibiotic use in COVID-19 is controversial although high prevalence rates of bacterial coinfection have been reported in previous similar global viral respiratory pandemics. Early data on the prevalence of antibiotic prescribing in COVID-19 indicates conflicting low and high prevalence of antibiotic prescribing which challenges antimicrobial stewardship programmes and increases risk of antimicrobial resistance (AMR).

Aim

To determine current prevalence of bacterial coinfection and antibiotic prescribing in COVID-19 patients.

Data source

OVID MEDLINE, OVID EMBASE, Cochrane and MedRxiv between January 2020 and June 2021.

Study eligibility

English language studies of laboratory-confirmed COVID-19 patients which reported (a) prevalence of bacterial coinfection and/or (b) prevalence of antibiotic prescribing with no restrictions to study designs or healthcare setting.

Participants

Adults (aged ≥ 18 years) with RT-PCR confirmed diagnosis of COVID-19, regardless of study setting.

Methods

Systematic review and meta-analysis. Proportion (prevalence) data was pooled using random effects meta-analysis approach; and stratified based on region and study design.

Results

A total of 1058 studies were screened, of which 22, hospital-based studies were eligible, compromising 76,176 of COVID-19 patients. Pooled estimates for the prevalence of bacterial co-infection and antibiotic use were 5.62% (95% CI 2.26–10.31) and 61.77% (CI 50.95–70.90), respectively. Sub-group analysis by region demonstrated that bacterial co-infection was more prevalent in North American studies (7.89%, 95% CI 3.30–14.18).

Conclusion

Prevalence of bacterial coinfection in COVID-19 is low, yet prevalence of antibiotic prescribing is high, indicating the need for targeted COVID-19 antimicrobial stewardship initiatives to reduce the global threat of AMR.

Tackling antimicrobial resistance across sub-Saharan Africa: current challenges and implications for the future

INTRODUCTION

Antimicrobial resistance (AMR) is a concern as this increases morbidity, mortality, and costs, with sub-Saharan Africa having the highest rates globally. Concerns with rising AMR have resulted in international, Pan-African, and country activities including the development of national action plans (NAPs). However, there is variable implementation across Africa with key challenges persisting.

AREAS COVERED

Consequently, there is an urgent need to document current NAP activities and challenges across sub-Saharan Africa to provide future guidance. This builds on a narrative review of the literature.

EXPERT OPINION

All surveyed sub-Saharan African countries have developed their NAPs; however, there is variable implementation. Countries including Botswana and Namibia are yet to officially launch their NAPs with Eswatini only recently launching its NAP. Cameroon is further ahead with its NAP than these countries; though there are concerns with implementation. South Africa appears to have made the greatest strides with implementing its NAP including regular monitoring of activities and instigation of antimicrobial stewardship programs. Key challenges remain across Africa. These include available personnel, expertise, capacity, and resources to undertake agreed NAP activities including active surveillance, lack of focal points to drive NAPs, and competing demands and priorities including among donors. These challenges are being addressed, with further co-ordinated efforts needed to reduce AMR.

Evaluation of antibiotic prescribing for ambulatory patients seeking primary dental care services in a public hospital in Ghana: a clinical audit study

Background

One in 10 of all antibiotic prescriptions globally are for dental conditions with 80% of them being inappropriate, making it a potential driver of antimicrobial resistance.

Objectives

To evaluate the appropriateness of antibiotic use among ambulatory patients seeking dental care services in a public hospital in Ghana.

Methods

A retrospective clinical audit was conducted by extracting the medical records of all patients seeking dental care at the ambulatory care clinic of Keta Municipal Hospital (KMH) from January 2020 to December 2020 using the hospital’s electronic database. Descriptive statistics, bivariate and multivariate analysis were performed on the data collected.

Results

Overall, 1433 patient medical records were extracted from the database within the study period. The mean age of the patients identified was 39.9 years with almost two-thirds being female. The majority (91.1%, n = 1306) of them were attended to by a dental nurse. In total, 88.6% (n = 1269) of the patients received antibiotics and 87.5% (n = 1254) of antibiotics prescribed were non-compliant with Ghana Standard Treatment Guidelines. Three-quarters of the dental conditions were managed with dual antibiotics comprising amoxicillin and metronidazole. Antibiotic prescription was associated with age, gender, type of prescriber and type of dental condition diagnosed.

Conclusions

There is a high usage of antibiotics for dental conditions managed at the outpatient section of the hospital and most are inappropriate. Development of local guidelines supported by education of dental clinicians on empirical use of antibiotics is a suitable target for the antimicrobial stewardship team to address in KMH.

Impact of Parental Knowledge and Beliefs on HPV Vaccine Hesitancy in Kenya-Findings and Implications

Cervical cancer can be prevented by human papillomavirus (HPV) vaccination. However, parents can have concerns about vaccinating their daughters. Consequently, there is a need to identify prevalence and risk factors for HPV vaccine hesitancy among parents in Kenya. A descriptive cross-sectional study was conducted among parents with children aged 9−14 years attending a leading referral hospital in Kenya. Data on sociodemographic traits, HPV knowledge, beliefs and vaccine hesitancy were collected. Out of 195 participants, 183 (93.5%) were aged >30 years. Thirty-four (46.4%) of males and 39 (35.1%) of females did not know that the vaccine is given to prevent HPV infection. Encouragingly, levels of vaccine acceptance were high (90%) although one-third (37.9%) had a negative perception about the effectiveness of the vaccine, with vaccine hesitancy attributed to safety concerns (76%) and feelings that the child was too young (48%). Positive beliefs and knowledge of the vaccine were positively associated with parental willingness to vaccinate their children. Low levels of parenteral education and a younger age among mothers were negatively associated with willingness to vaccinate. Most parents (59%) would consult their daughters before vaccination, and 77% (n = 150) recommended early sex education. Despite low knowledge levels, there was high parental willingness to have their children vaccinated.

Characteristics and Management of Children With Suspected COVID-19 Admitted to Hospitals in India: Implications for Future Care

Introduction: There is a growing focus on researching the management of children with COVID-19 admitted to hospital, especially among developing countries with new variants alongside concerns with the overuse of antibiotics. Patient care can be improved with guidelines, but concerns with the continued imprudent prescribing of antimicrobials, including antibiotics, antivirals, and antimalarials.

Objective: Consequently, a need to document the current management of children with COVID-19 across India. Key outcome measures included the percentage of prescribed antimicrobials, adherence to current guidelines, and mortality.

Methodology: A point prevalence study using specially developed report forms among 30 hospitals in India.

Results: The majority of admitted children were aged between 11 and 18 years (70%) and boys (65.8%). Reasons for admission included respiratory distress, breathing difficulties, and prolonged fever. 75.3% were prescribed antibiotics typically empirically (68.3% overall), with most on the Watch list (76.7%). There were no differences in antibiotic prescribing whether hospitals followed guidelines or not. There was also appreciable prescribing of antimalarials (21.4% of children), antivirals (15.2%), and antiparasitic medicines (27.2%) despite limited evidence. The majority of children (92.2%) made a full recovery.

Conclusion: It was encouraging to see low hospitalization rates. However, concerns about high empiric use of antibiotics and high use of antimalarials, antivirals, and antiparasitic medicines exist. These can be addressed by instigating appropriate stewardship programs.

Regional variation in longitudinal trajectories of primary care opioids prescribing across Health Boards in Scotland: a population-based study

BACKGROUND

This study aims to describe the longitudinal trajectory of opioid prescribing at the practice level and assess associated factors, including Health Boards and socioeconomic status.

RESEARCH DESIGN AND METHODS

This drug utilization research used practice-level dispensing data from 2016 to 2018. Practice-level prescription opioids dispensed were quantified by the defined daily doses (DDDs) per 1000 registrants. Group-based trajectory models were used to identify groups of practices with similar trajectories based on the difference in monthly opioid utilization. Characteristics of registrants were associated with the trajectory by a conditional logistic regression and the prescription opioids dispensed by a random-effect regression model.

RESULTS

Of the 798 practices, 29.5% increased opioid prescription by an additional 100 DDDs/1000 registrants/month during 2017 and 2018. Practice in southwest Scotland tended to be categorized into the group with increasing opioid utilization. Deprived socioeconomic status was associated with increasing opioid utilization (odds ratio: 2.2; 95% confidence interval: 1.5, 3.2) or higher annual opioid utilization (coefficient: 358.2; 95% confidence interval: 327.6, 388.8).

CONCLUSIONS

Increasing opioid utilization over time was related to deprived socioeconomic status associated with chronic pain conditions and inequality in pain services. Further strategies to balance inequality are needed, which needs further investigation.

Development and Validation of a Tool to Improve Community Pharmacists’ Surveillance Role in the Safe Dispensing of Herbal Supplements

Background: There has been an appreciable increase in the use of herbal supplements, including immune boosters, during the current COVID-19 pandemic. However, there are concerns with falsified herbal supplements.

Objectives: Developed a new questionnaire that can potentially help community pharmacists identify the extent of falsified herbal supplements.

Methods: A 9-month cross sectional study was conducted among 500 community pharmacies across United Arab Emirates. A new 5-factor, 24-itmes scale was developed based on current labelling requirements across countries and piloted. This included seven items on identified uses and contraindication, seven items on hazard identification, four items on product identity, three items on packaging and product insert and three items on product handling and storage. The face and content validity of the scale was assessed via the content validity index (CVI). Its construct validity was tested using an exploratory factor analysis (EFA) via principally component analysis (PCA). The model was subsequently confirmed through partial confirmatory factor analysis (PCFA). Its reliability was assessed via test-retest reliability, internal consistency, item internal consistency (IIC), and intraclass correlation coefficients (ICCs).

Results: The CVI of the finalized questionnaire was 0.843. The Kaiser-Meyer-Olkin measure of sampling adequacy was 0.891, and Bartlett’s test of sphericity indicated significance (p-value < 0.001). Confirmation of the subsequent 5-domains was achieved through PCFA using maximum likelihood analysis with oblimin rotation. The PCFA obtained values was 0.962 for NFI, 0.977 for CFI, and 0.987 for the Tucker Lewis Index. All values were greater than 0.95, and the RMSEA value was 0.03 (i.e., less than 0.06). Consequently, the model had a good fit. All domains demonstrated Cronbach’s alpha coefficients above 0.70, with 0.940 for the full instrument. Meanwhile, all items met the IIC correlation standard of ≥0.40. The instrument presented good ICC statistics of 0.940 (0.928–0.950) as well as statistical significance (p < 0.001). Community pharmacists with more than 10 experience years were more likely to identify falsified herbal supplements compared to those with 1–10 years experience (p < 0.001).

Conclusion: This study developed and validated a new instrument to identify safe herbal supplements, which should enhance the role of the community pharmacists in the safe and effective treatment of suitable patients with herbal supplements.

What patient assessment skills do pharmacist independent prescribers require to prescribe immunomodulators in myeloma?

AIM

To gain consensus on the patient assessment skills required by pharmacist independent prescribers prescribing immunomodulators in myeloma across National Health Service Scotland.

METHODS

This was a two-phase study which used nominal group technique to gain local consensus followed by a two-round eDelphi questionnaire to gain national consensus across all cancer networks.

SETTING

This project was conducted across the three cancer networks within NHS Scotland: South East Scotland Cancer Network; West of Scotland Cancer Network and North Cancer Alliance.

SUBJECTS

Participants were invited from each cancer network (South East Scotland Cancer Network, West of Scotland Cancer Network and North Cancer Alliance) and included haematology consultants, haematology specialist registrars, haematology advanced nurse practitioners and haematology pharmacists.

RESULTS

There were five participants in the nominal group technique. Twenty-two out of 31 patient assessment skills gained local consensus, seven patient assessment skills did not gain consensus and two patient assessment skills were deemed irrelevant. There were 12 and 14 participants in round one and two of the eDelphi questionnaire, respectively. Twenty-nine patient assessment skills were included in the first-round questionnaire and 21 gained consensus. The remaining eight patient assessment skills were included in round two where seven did not achieve consensus and one achieved disagreement consensus.

CONCLUSION

This research outlines 21 patient assessment skills required for pharmacist independent prescribers to prescribe immunomodulators for myeloma patients according to haematology specialists in Scotland. Discussion on patient assessment skills without consensus showed that the pharmacist independent prescribers would have a shared responsibility with the consultant. This work should inform the development of a competency framework to allow training of pharmacist independent prescribers in Scotland. Some patient assessment skills could be transferrable for pharmacist independent prescribers prescribing systemic anti-cancer therapy for other haematological malignancies.

The impact of the COVID-19 pandemic lockdown measures on the prescribing trends and utilization of opioids in the English primary care setting: segmented-liner regression analysis

BACKGROUND

The COVID-19 lockdown has resulted in limited access to most of the conventional chronic pain management services. Subsequently, changes in opioids' utilization could be expected. This study assessed the impact of the first COVID-19 lockdown on opioid utilization using aggregated-level, community dispensing dataset covering the whole English population.

RESEARCH DESIGN AND METHODS

A segmented-linear regression analysis was applied to monthly dispensed opioid prescriptions from March 2019 to March 2021. Opioid utilization was measured using the number of opioids' items dispensed/1000 inhabitants and Defined Daily Dose (DDD)/1000 inhabitants/day during 12-months pre/post the lockdown in March 2020 stratified by strong and weak opioids.

RESULTS

For all opioids' classes, there were nonsignificant changes in the number of opioids' items dispensed/1000 inhabitants trend pre-lockdown, small increases in their level immediately post-lockdown, and a non-significant decline in the trend post-lockdown. Similarly, a non-significant reduction in the DDD/1000 inhabitant/day baseline trend pre-lockdown, nonsignificant immediate increases in the level post-lockdown, and declines in the trend post-lockdown for all opioids' classes were observed.

CONCLUSION

Unexpectedly, opioid utilization does not appear to have been significantly affected by the lockdown measures during the study period. However, patient-level data is needed to determine more accurate estimates of any changes in the opioid prescribing including incident prescribing/use.

Challenges and Opportunities With Routinely Collected Data on the Utilization of Cancer Medicines. Perspectives From Health Authority Personnel Across 18 European Countries

Background: Rising expenditure for new cancer medicines is accelerating concerns that their costs will become unsustainable for universal healthcare access. Moreover, early market access of new oncology medicines lacking appropriate clinical evaluation generates uncertainty over their cost-effectiveness and increases expenditure for unknown health gain. Patient-level data can complement clinical trials and generate better evidence on the effectiveness, safety and outcomes of these new medicines in routine care. This can support policy decisions including funding. Consequently, there is a need for improving datasets for establishing real-world outcomes of newly launched oncology medicines.

Aim: To outline the types of available datasets for collecting patient-level data for oncology among different European countries. Additionally, to highlight concerns regarding the use and availability of such data from a health authority perspective as well as possibilities for cross-national collaboration to improve data collection and inform decision-making.

Methods: A mixed methods approach was undertaken through a cross-sectional questionnaire followed-up by a focus group discussion. Participants were selected by purposive sampling to represent stakeholders across different European countries and healthcare settings. Descriptive statistics were used to analyze quantifiable questions, whilst content analysis was employed for open-ended questions.

Results: 25 respondents across 18 European countries provided their insights on the types of datasets collecting oncology data, including hospital records, cancer, prescription and medicine registers. The most available is expenditure data whilst data concerning effectiveness, safety and outcomes is less available, and there are concerns with data validity. A major constraint to data collection is the lack of comprehensive registries and limited data on effectiveness, safety and outcomes of new medicines. Data ownership limits data accessibility as well as possibilities for linkage, and data collection is time-consuming, necessitating dedicated staff and better systems to facilitate the process. Cross-national collaboration is challenging but the engagement of multiple stakeholders is a key step to reach common goals through research.

Conclusion: This study acts as a starting point for future research on patient-level databases for oncology across Europe. Future recommendations will require continued engagement in research, building on current initiatives and involving multiple stakeholders to establish guidelines and commitments for transparency and data sharing.

Obesity association with antidiabetic drugs’ prescription among patients with type 2 diabetes mellitus: a systematic review and meta-analysis

Introduction

Type 2 diabetes mellitus (T2DM) is a chronic disease of persistent elevation in blood glucose level. Several antidiabetic drugs (ADDs) with different features are currently available for T2DM management (1). The selection of appropriate ADDs is crucial for preventing/attenuating diabetes-related complications(1). All guidelines agreed on metformin to be an initial therapy for patients diagnosed with T2DM, yet the selection of an intensifying therapy or alternative initial therapy are lacking any agreements (1). Consequently, the selection of ADDs could be linked to multiple factors (2). Since obesity is a risk factor for T2DM and ADDs have variable effect on body weight, obesity is an important factor that could be associated with ADDs’ selection.

Aim

This systematic review (SR) and meta-analysis (MA) aimed to overview and quantify obesity association with the selection of ADDs among type 2 diabetic patients.

Methods

A systematic literature search was conducted on multiple databases. Eligible studies were selected based on the following inclusion criteria: quantitative observational studies, evaluated obesity association with ADDs’ prescription, in outpatient setting, and published in English over the period of Jan/2009-April/2021. Studies on other types of diabetes, about switching therapy, or published before 2009 were excluded. The following items were extracted from identified articles: study details as author, year, and method, participants’ characteristics as age and gender, type of investigated ADDs, comparison group, and stage of treatment, as well as type of analysis test. Extracted data was synthesized quantitively utilising a three-level MA approach as some studies reported more than one effect-size because of examining multiple ADDs. It was based on odds ratio and 95%confidence interval.

Results

A total of 21 studies evaluated the association of obesity with ADDs’ prescription was identified. All except one were included in the MA which contributed to a total of 66 effect sizes from all investigated ADDs. The pooled estimate of obesity association with the prescription of ADDs including all groups was 1.19[0.85 -1.67]. A subgroup analysis showed a significant difference according to the type of ADDs (p&lt; .0001). A positive significant association was found with glucagon-Like peptide receptor agonist (GLP1-RA), sodium glucose transporter 2 inhibitors (SGLT2-I), and metformin prescriptions (pooled estimate: 2.35 [1.54-3.59], 1.89[1.33-2.68], and 1.22[1.08-1.37], respectively). Whereas a negative significant association was found with sulfonylurea prescription (pooled estimate: 0.76 [0.62-0.93]). The pooled estimate of thiazolidinedione, dipeptidyl-peptidase 4 inhibitors, and insulin showed a non-significant association with obesity. None of the investigated variables showed significant influence on the overall result including stage of treatment and quality of study (p &gt;0.05).

Conclusion

Obesity is an important factor influencing ADDs’ prescription. Patients with higher weight were more likely to get ADDs with weight losing or neutral effect as GLP1-RA, SGLT2-I, and metformin. This reflects some adherence of clinical practice to the variability in drugs’ features as indicated from the consistent findings of obesity as a factor affecting ADDs’ selection with the weight effect of ADDs. Yet, further studies are required because of limited number of studies examined each antidiabetic group.

The impact of the COVID-19 pandemic lockdown measures on the prescribing trends and utilisation of opioids in the English primary care setting: a segmented-linear regression analysis

Introduction

The emergence of the COVID-19 pandemic presented unprecedented challenges for healthcare systems, including patients with chronic pain. The COVID-19 lockdown has resulted in limited access to most of the conventional chronic pain management services. Subsequently, changes in opioid utilisation could be expected (1).

Aim

To assess the impact of the first COVID-19 lockdown on opioid utilisation using aggregated-level, community dispensing dataset covering the whole English population.

Methods

This repeated cross-sectional study applied a segmented-linear regression analysis to monthly dispensed opioid prescriptions using the Prescription Cost Analysis database (PCA), from March 2019-March 2021. Opioid utilisation was measured using number of items dispensed/1000 inhabitants and Defined Daily Dose (DDD)/1000 inhabitants/day during 12-months pre and post the COVID-19 lockdown introduced in England in March 2020, stratified by strong and weak opioids.

Results

There were insignificant changes in the number of items dispensed/1000 inhabitants trend pre-COVID-19 lockdown for total, strong, and weak opioids (β1=-0.064, β1=-0.055, β1=0.009, p&gt;0.05, respectively). Immediately post-lockdown, there were small increases in the level of total, strong, and weak opioids (β2=0.494, β2=0.448, β2=0.045) albeit non-significant. There was a non-significant decline in the trend post-lockdown for all opioids’ classes.

Similarly, a non-significant reduction in the DDD/1000 inhabitants/day baseline trend was observed pre-lockdown for total, strong, and weak opioids (β1=-0.028, β1=-0.027, β1=-0.001, p&gt;0.05, respectively). There were immediate increases in the level post-lockdown (β2=0.386, β2=0.360, β2=0.026, p&gt;0.05) for total, strong, and weak opioids respectively. Subsequently, a decline in the trend post-lockdown for all opioids’ classes was observed.

Discussion/conclusion

Unexpectedly, the study’s findings showed an overall stable trend in the utilisation of opioids pre and post COVID-19 in England. The stable trends observed in our study could be due to multiple factors. Firstly, patient level data and information about the specific indication were unavailable in the PCA dataset. This is a limitation as we were unable to examine the trend between the existing and new (incident) patients to obtain more accurate data for opioid utilisation. Moreover, the guidelines and strategies that have been implemented with regard to opioid prescription in the UK (2), to help regulate and minimize the harm from their use in chronic pain management may have had an impact.

To our knowledge, this is the first study to estimate and quantify the impact of the COVID-19 pandemic on opioid utilisation using a segmented regression analysis. This was facilitated by the study focusing on opioid prescription over a 25-month period, i.e. 12 months either side of the pandemic, to predict a trend line for opioid prescription. This duration was beneficial as it gave us adequate time to investigate if COVID-19 had affected prescribing volumes. The limitations include lacking patient level data and specific indications for prescribing opioids. Also, over-the-counter codeine products were not included in the study as the datasets we used included only prescription medicines in ambulatory care

Our findings support the further monitoring and investigation of patient level data to explore the impact of the pandemic on opioid prescription and to continue promoting the safe and effective use of opioids.

Assessing knowledge, attitude and practice of community pharmacists on the pain management and implications in UAE children

Objective:

There are concerns with the optimal management of pain in children, with sub-optimal management negatively impacting on physical, emotional social functioning, exacerbated by pain in children being multi-modal. Community pharmacists across countries play an important role in managing pain in patients including children’s pain. Consequently, the objective of this study is to assess knowledge, attitudes and practices (KAP) of pain management in children among community pharmacists in UAE.

Methods:

A cross-sectional study was conducted using a structured questionnaire that was developed and piloted. The final questionnaire, which comprised two parts, had acceptable validity and internal consistency.

Results:

867 out of 922 community pharmacists took part in UAE (94% response rate) and were visited by trained researchers. The most from independent pharmacies (53.9%) and having more than 10 years of experience (68.9%). The overall KAP score was 70%, with gender, pharmacy type, years of experience, educational level and position significantly associated with KAP. Encouraging knowledge areas included pain is one of the vital signs in children (88.6%), the intensity of pain should be rated by a pharmacist before discussing treatment options (92.2%) and the choice of treatment should depend on issues including intensity and duration (87.2%). Areas of concern included the contents of the WHO analgesic ladder (32.0%) and children may sleep in spite of severe pain (42.9%).

Conclusion:

There were areas of good knowledge of pain management among community pharmacists in UAE. Areas of concern including knowledge of the WHO analgesic ladder need to be addressed as part of future educational input during training and post qualification.

Opportunities and challenges when using record linkage of routinely collected electronic health care data to evaluate outcomes of systemic anti-cancer treatment in clinical practice

The efficacy and safety of cancer medicines as reported from randomised clinical trials do not always translate into similar benefits in routine clinical practice; hence, post-marketing studies are a useful addition to the evidence base. With recent advances in digital infrastructure and the advent of electronically available health records, linkage of routinely collected data has emerged as a promising evaluation method for these studies. This paper discusses the opportunities and challenges when applying an electronic record linkage methodology with respect to systemic anti-cancer therapy by showcasing exemplar studies conducted over a three-year period in Scotland, and highlights some of the potential pitfalls spanning the entire breadth and depth of the research process. Our experiences as an interdisciplinary team indicate that there is scope to conduct large cohort studies to generate results from routine clinical practice within a reasonable time frame; however, close collaboration between researchers, data controllers and clinicians is required in order to obtain valid and meaningful results.

Barriers and facilitators of adherence to antiretroviral treatment at a public health facility in Ghana: a mixed method study

BACKGROUND

HIV/AIDS is a disease of global public health concern with high morbidity and mortality rates. Poor adherence to antiretroviral therapy (ART) increases the risk of viral drug resistance and reduces treatment effectiveness towards viral suppression leading to disease progression, greater risk of death and increased risk of viral transmission. The study sought to assess current adherence levels to ART among patients in Ghana, exploring barriers and enablers of adherence to it, to provide future guidance to all key stakeholder groups.

METHOD

A mixed method approach was used comprising of a cross-sectional survey of patients followed by a focused group discussion with patients and an in-depth interview of four key health professionals working in the ART clinic of Atua Government Hospital, a primary care health facility in the Eastern Region of Ghana. A structured questionnaire was used to assess current adherence levels and their determinants among 231 randomly selected patients attending the clinic between July to September, 2019. Quantitative data were analysed using bivariate and multivariate methods while qualitative data were analysed using thematic framework approach.

RESULTS

Adherence levels was found to be 42.9% among our study population. Lower adherence to ART was associated with patients' belief in herbal medicine (aOR =0.34 CI: 0.19-0.61). Other barriers identified from the qualitative analysis included low motivation arising from pill fatigue, forgetfulness, frequent stock out of medicines, long waiting times and worrying side-effects; while enablers, on the other hand, included measures that ensure improved assessment of adherence and health facility-related activities that improve patient satisfaction with ART services. Conclusion: Adherence to ART among patients living with HIV was sub-optimal in our study population. Understanding of the barriers and factors that enable adherence to ART is a key step to developing evidence-based adherence improvement strategies to enhance clinical outcomes.

Management of Children Admitted to Hospitals across Bangladesh with Suspected or Confirmed COVID-19 and the Implications for the Future: A Nationwide Cross-Sectional Study

There is an increasing focus on researching children admitted to hospital with new variants of COVID-19, combined with concerns with hyperinflammatory syndromes and the overuse of antimicrobials. Paediatric guidelines have been produced in Bangladesh to improve their care. Consequently, the objective is to document the management of children with COVID-19 among 24 hospitals in Bangladesh. Key outcome measures included the percentage prescribed different antimicrobials, adherence to paediatric guidelines and mortality rates using purposely developed report forms. The majority of 146 admitted children were aged 5 years or under (62.3%) and were boys (58.9%). Reasons for admission included fever, respiratory distress and coughing; 86.3% were prescribed antibiotics, typically parenterally, on the WHO ‘Watch’ list, and empirically (98.4%). There were no differences in antibiotic use whether hospitals followed paediatric guidance or not. There was no prescribing of antimalarials and limited prescribing of antivirals (5.5% of children) and antiparasitic medicines (0.7%). The majority of children (92.5%) made a full recovery. It was encouraging to see the low hospitalisation rates and limited use of antimalarials, antivirals and antiparasitic medicines. However, the high empiric use of antibiotics, alongside limited switching to oral formulations, is a concern that can be addressed by instigating the appropriate programmes.
