The links between the amount of antipsychotic medication prescribed at GP practice level, local demographic factors and medication selection

AimsTo examine the factors that relate to antipsychotic prescribing in general practices across England and how these relate to cost changes in recent years.BackgroundAntipsychotic medications are the first-line pharmacological intervention for severe mental illnesses(SMI) such as schizophrenia and other psychoses, while also being used to relieve distress and treat neuropsychiatric symptoms in dementia.Since 2014 many antipsychotic agents have moved to generic provision. In 2017_18 supplies of certain generic agents were affected by substantial price increases.MethodThe study examined over time the prescribing volume and prices paid for antipsychotic medication by agent in primary care and considered if price change affected agent selection by prescribers.The NHS in England/Wales publishes each month the prescribing in general practice by BNF code. This was aggregated for the year 2018_19 using Defined Daily doses (DDD) as published by the World Health Organisation Annual Therapeutic Classification (WHO/ATC) and analysed by delivery method and dose level. Cost of each agent year-on-year was determined.Monthly prescribing in primary care was consolidated over 5 years (2013-2018) and DDD amount from WHO/ATC for each agent was used to convert the amount to total DDD/practice.ResultDescriptionIn 2018_19 there were 10,360,865 prescriptions containing 136 million DDD with costs of £110 million at an average cost of £0.81/DDD issued in primary care. We included 5,750 GP Practices with practice population >3000 and with >30 people on their SMI register.Effect of priceIn 2017_18 there was a sharp increase in overall prices and they had not reduced to expected levels by the end of the 2018_19 evaluation year. There was a gradual increase in antipsychotic prescribing over 2013-2019 which was not perturbed by the increase in drug price in 2017/18.RegressionDemographic factorsThe strongest positive relation to increased prescribing of antipsychotics came from higher social disadvantage, higher population density(urban), and comorbidities e.g. chronic obstructive pulmonary disease(COPD). Higher %younger and %older populations, northerliness and non-white (Black and Minority Ethnic (BME)) ethnicity were all independently associated with less antipsychotic prescribing.Prescribing FactorsHigher DDD/general practice population was linked with higher %injectable, higher %liquid, higher doses/prescription and higher %zuclopenthixol. Less DDD/population was linked with general practices using higher %risperidone and higher spending/dose of antipsychotic.ConclusionHigher levels of antipsychotic prescribing are driven by social factors/comorbidities. The link with depot medication prescriptions, alludes to the way that antipsychotics can induce receptor supersensitivity with consequent dose escalation.

Prevalence of inflammatory bowel disease in the Australian general practice population: A cross-sectional study

The burden of inflammatory bowel disease (IBD) in Australia is increasing but national data about the current prevalence are limited. We aimed to estimate the prevalence of IBD (including Crohn’s disease, ulcerative colitis and unspecified IBD) as well as Crohn’s disease and ulcerative colitis separately in a general practice population in Australia. We also assessed risk factors associated with Crohn’s disease and ulcerative colitis. We conducted a cross-sectional study using data from MedicineInsight, a national database of general practice electronic health records, from 1 July 2017 to 30 June 2019. The prevalence of IBD was calculated and stratified by sociodemographic characteristics. Logistic regression analysis was conducted to assess risk factors associated with Crohn’s disease and ulcerative colitis. The study comprised 2,428,461 regular patients from 481 practices. The estimated crude prevalence of IBD was 653 per 100,000 patients; Crohn’s disease was 306 per 100,000 and ulcerative colitis was 334 per 100,000. Males were independently associated with a lower risk of Crohn’s disease (OR: 0.86; 95% CI: 0.81, 0.90) but a greater risk of ulcerative colitis (OR: 1.12; 95% CI: 1.06, 1.17) than females. Compared to non-smokers, patients who were current smokers were associated with a greater risk of Crohn’s disease (OR: 1.13; 95% CI: 1.04, 1.23) but a lower risk of ulcerative colitis (OR: 0.52; 95% CI: 0.47, 0.57). Other factors positively associated with both Crohn’s disease and ulcerative colitis were age (≥ 25 years), non-Indigenous status and socioeconomic advantage. Our findings provide a current estimate of the prevalence of IBD, Crohn’s disease and ulcerative colitis in a large national general practice population in Australia and an assessment of the factors associated with Crohn’s disease and ulcerative colitis. These data can assist in estimating the health burden and costs, and planning for health services.

EXPRESS: Comparison of four high throughput, automated immunoassays for the detection of SARS-CoV-2 antibodies

Background: A number of immunoassays have been developed to measure antibodies specific to SARS-CoV-2. More data is required on their comparability, particularly amongst those with milder infections and in the general practice population. The aim of this study was to compare four high throughput automated anti SARS-CoV-2 assays using samples collected from hospitalised patients and healthcare workers with confirmed SARS-CoV-2 infection. In addition, we collected general practice samples to compare antibody results and determine seroprevalence. Methods: Samples were collected from 57 hospitalised patients and 9 healthcare workers at 14 days and at 28 days following confirmed SARS-CoV-2 infection. Samples were also collected from 225 patients presenting to general practice. Four assays were used: Abbott Architect IgG, Beckman Coulter DxI 800 IgG, Roche Cobas e801 total antibody and Siemens Advia Centaur XPT total antibody. Results: All 4 assays showed concordance at 14 days in 83.9% of hospitalised patients and in 66.7% of healthcare workers. All 4 assays showed concordance at 28 days in 88.4% of hospitalised patients and 77.8% of healthcare workers. The sensitivity to detect recent infection was higher for the IgG assays than the total assays. All 4 assays showed concordance of 95.1% in the general practice population. Seroprevalence ranged from 4.9-5.8% depending on the assay used. Conclusions: All 4 assays showed excellent comparability but it may be possible to obtain a negative result for any of the anti SARS-CoV-2 assays in patients with confirmed previous SARS-CoV-2 infection. An equivocal range would be useful for all anti SARS-CoV-2 assays.

Cross-sectional study evaluating the association between integrated care and health-related quality of life (HRQOL) in Dutch primary care

ObjectivesThe aim of this study was to evaluate the association between integrated care and health-related quality of life (HRQOL) in a primary care practice population.DesignA cross-sectional survey study.SettingPrimary care practice population.ParticipantsA sample (n=5562) of patients in two general practitioner practices in the Netherlands.Primary outcome measuresThe Rainbow Model of Integrated Care Measurement Tool patient version and EQ-5D was used to assess integrated service delivery and HRQOL. The association between integrated care and HRQOL groups was analysed using multivariate logistic regression.ResultsOverall, 933 respondents with a mean age of 62 participated (20% response rate) in this study. The multivariate analysis revealed that positive organisational coordination experiences were linked to better HRQOL (OR=1.87, 95% CI 1.18 to 2.95), and less anxiety and depression problems (OR=0.36, 95% CI 0.20 to 0.63). Unemployment was associated with a poor HRQOL (OR=0.15, 95% CI 0.08 to 0.28). Ageing was associated with more mobility (OR=1.06, 95% CI 1.04 to 1.09), self-care (OR=1.06, 95% CI 1.02 to 1.11), usual activity (OR=1.03, 95% CI 1.01 to 1.05) and pain problems (OR=1.02, 95% CI 1.01 to 1.04). Being married improved the overall HRQOL (OR=1.60, 95% CI 1.13 to 2.26) and decreased anxiety and depression (OR=0.47, 95% CI 0.31 to 0.72). Finally, females had a poor overall HRQOL (OR=1.67, 95% CI 0.48 to 0.93) and more pain and discomfort problems (OR=1.47, 95% CI 1.11 to 1.95).ConclusionThis study shows for the first time that organisational coordination activities are positively associated with HROQL of adult patients in a primary care context, adding to the evidence of an association between integrated care and HRQOL. Also, unemployment, ageing and being female are accumulating risk factors that should be considered when designing integrated primary care programmes. Further research is needed to explore how various integration types relate to HRQOL for people in local communities.

Management of giant cell arteritis among general practitioners from Genoa, Italy: a web-based survey

Giant cell arteritis (GCA) is the most common form of vasculitis of the adult. General practitioners (GPs) are usually the first physicians who take care of GCA patients. In this study, the awareness of GPs from Genoa, Italy, regarding GCA was investigated by a web-based survey. A web-based questionnaire was sent by mail to 775 Italian GPs. It included 12 multiple choice questions regarding practice seniority, practice population size, number of GCA patients followed, and GPs’ diagnostic and therapeutic approach. Of the 775 GPs involved, 76 (9.8%) answered. Thirty-three/75 (44%) declared that they did not see patients with GCA and the remaining 42 (56%) that they diagnose between one and two patients per year. New headache onset was the presenting feature of GCA for the majority of GPs (78.3%). GCA was diagnosed on the basis of clinical presentation alone by 35.2% of them, of temporal artery biopsy by 49.3%, and by imaging, including ultrasound and magnetic resonance imaging, by 15.5%. The referral pattern was mainly toward rheumatologists (68.5%). Only 27.8% GPs declared they start treatment at the first clinical suspicion, with the others waiting for laboratory and imaging examinations or specialist consultation. The doses of glucocorticoids used were in keeping with current guidelines. The management of GCA by GPs from Genoa is in general correct, with the exceptions of excessive confidence in headaches for diagnosis and of the timing of GC initiation. These points suggest that a program of information and education for GPs is warranted.

Phenotyping the shoulder patient based on ultrasound-detected pathologies: a cross-sectional study in general practice

Background Shoulder complaints arise from a single pathology or a combination of different underlying pathologies that are hard to differentiate in general practice. Subgroups of pathologies have been identified on the basis of ultrasound imaging that might affect treatment outcomes. Objective Our aim was to validate the existence of different subgroups of patients with shoulder complaints, based on ultrasound-detected pathology, and compare clinical features among them. Profiling shoulder patients into distinct shoulder pathology phenotypes could help designing tailored treatment trials. Methods This was a cross-sectional study in general practice. Data were extracted from 840 first visit patient records at a single diagnostic centre in the Netherlands. Exclusion criteria were age <18 years and previous shoulder surgery. Latent class analysis was used to uncover cross-combinations of ultrasound detected pathologies, yielding subgroups of shoulder patients. The uncovered subgroups were compared for demographic and clinical characteristics. Results We uncovered four distinct subgroups of patients with shoulder complaints: (i) Frozen shoulder group (11%), (ii) Limited pathology group (44%), (iii) Degenerative pathology group (31%) and (iv) Calcifying tendinopathy group (15%). Group comparisons showed significant differences in demographic and clinical characteristics among subgroups, consistent with the literature. Conclusion In a general practice population, we uncovered four different phenotypes of shoulder patients on the basis of ultrasound detected pathology. These phenotypes can be used designing tailored treatment trials in patients with shoulder complaints.

Links between the amount of antipsychotic medication prescribed per population at general practice level, local demographic factors and medication selection

Background Antipsychotic medications are the first-line pharmacological intervention for severe mental illnesses (SMI) such as schizophrenia and other psychoses, while also being used to relieve distress and treat neuropsychiatric symptoms in dementia. Our aim was to examine the factors relating to antipsychotic prescribing in general practices across England and how cost changes in recent years have impacted on antipsychotic prescribing. Methods The study examined over time the prescribing volume and prices paid for antipsychotic medication by agent in primary care. Monthly prescribing in primary care was consolidated over 5 years (2013–2018) and DDD amount from WHO/ATC for each agent was used to convert the amount to total DDD/practice. The defined Daily Dose (DDD is the assumed average maintenance dose per day for a drug used for its main indication in adults. Results We included 5750 general practices with practice population > 3000 and with > 30 people on their SMI register. In 2018/19 there were 10,360,865 prescriptions containing 136 million DDD with costs of £110 million at an average cost of £0.81/DDD issued in primary care. In 2017/18 there was a sharp increase in overall prices and they had not reduced to expected levels by the end of the 2018/19 evaluation year. There was a gradual increase in antipsychotic prescribing over 2013–2019 which was not perturbed by the increase in drug price in 2017/18. The strongest positive relation to increased prescribing of antipsychotics came from higher social disadvantage, higher population density (urban), and comorbidities e.g. chronic obstructive pulmonary disease (COPD). Higher % younger and % older populations, northerliness and non-white (Black and Minority Ethnic(BAME)) ethnicity were all independently associated with less antipsychotic prescribing. Higher DDD/general practice population was linked with higher proportion(%) injectable, higher %liquid, higher doses/prescription and higher %zuclopenthixol depot. Less DDD/population was linked with general practices using higher % risperidone and higher spending/dose of antipsychotic. Conclusions The levels of antipsychotic prescribing at general practice level are driven by social factors/comorbidities. We found a link between depot prescriptions with higher antipsychotic DDD and risperidone prescriptions with lower antipsychotic DDD. It is important that all prescribers are aware of these drivers / links.

The primary care workforce in Europe: a cross-sectional international comparison of rural and urban areas and changes between 1993 and 2011

Rural areas have problems in attracting and retaining primary care workforce. This might have consequences for the existing workforce. We studied whether general practitioners (GPs) in rural practices differ by age, sex, practice population and workload from those in less rural locations and whether their practices differ in resources and service profiles. We used data from 2 studies: QUALICOPC study collected data from 34 countries, including 7183 GPs in 2011, and Profiles of General Practice in Europe study collected data from 32 countries among 7895 GPs in 1993. Data were analyzed using multilevel analysis. Results show that the share of female GPs has increased in rural areas but is still lower than in urban areas. In rural areas, GPs work more hours and provide more medical procedures to their patients. Apart from these differences between locations, overall ageing of the GP population is evident. Higher workload in rural areas may be related to increased demand for care. Rural practices seem to cope by offering a broad range of services, such as medical procedures. Dedicated human resource policies for rural areas are required with a view to an ageing GP population, to the individual preferences and needs of the GPs, and to decreasing attractiveness of rural areas.
