A case-control study comparing the incidence of early symptoms in pancreatic and biliary tract cancer.

Pancreatic ductal adenocarcinoma (PDAC) and biliary tract cancers (BTC) are often diagnosed late and at an advanced stage. Population-based screening programmes do not exist and diagnosis is primarily dependent on symptom recognition. Recently symptom-based cancer decision support tools (CDSTs) have been introduced into primary care practices throughout the UK to support general practitioners (GPs) in identifying patients with suspected PDAC. However, future refinement of these tools to improve their diagnostic accuracy is likely to be necessary

Family caregivers’ conceptualisation of quality end-of-life care for people with dementia: A qualitative study

BACKGROUND: People with dementia have been described as the ‘disadvantaged dying’ with poor end-of-life care. Towards the end of life, people with dementia cannot report on the care they receive. It is therefore important to talk to caregivers; however, few have explored the views about end-of-life care from the caregivers’ perspective. The majority of research on family caregivers has focussed on the burden and psychological impact of caring for a relative with dementia. AIM: This study aimed to explore the views of family caregivers about quality end-of-life care for people with dementia. DESIGN: Qualitative study using in-depth interviews and analysed using thematic analysis. SETTING/PARTICIPANTS: Purposive sampling from a third sector organisation’s caregiver network was used to recruit 47 caregivers in England (2012–2013), consisting of (1) family caregivers of someone who had recently received a diagnosis of dementia, (2) family caregivers currently caring for someone with dementia and (3) bereaved family caregivers. RESULTS: Three over-arching themes were derived from the interviewees’ discourse, including maintaining the person within, fostering respect and dignity and showing compassion and kindness. CONCLUSION: End-of-life care for people with dementia does not differ from care throughout the dementia trajectory. Throughout the findings, there is an implicit underlying theme of conflict: conflict between family caregivers and an increasingly systematised service of care and conflict between family caregivers and professionals. This study has in particular demonstrated the importance of the psycho-social aspects of care, aligning with the holistic definition of palliative care

Time trends in contraceptive prescribing in UK primary care 2000–2018: a repeated cross-sectional study

BACKGROUND: Over the last 20 years, new contraceptive methods became available and incentives to increase contraceptive uptake were introduced. We aimed to describe temporal trends in non-barrier contraceptive prescribing in UK primary care for the period 2000-2018. METHODS: A repeated cross-sectional study using patient data from the IQVIA Medical Research Data (IMRD) database. The proportion (95% CI) of women prescribed non-barrier contraception per year was captured. RESULTS: A total of 2 705 638 women aged 15-49 years were included. Between 2000 and 2018, the proportion of women prescribed combined hormonal contraception (CHC) fell from 26.2% (26.0%-26.3%) to 14.3% (14.2%-14.3%). Prescriptions for progestogen-only pills (POPs) and long-acting reversible contraception (LARC) rose from 4.3% (4.3%-4.4%) to 10.8% (10.7%-10.9%) and 4.2% (4.1%-4.2%) to 6.5% (6.5%-6.6%), respectively. Comparing 2018 data for most deprived versus least deprived areas, women from the most deprived areas were more likely to be prescribed LARC (7.7% (7.5%-7.9%) vs 5.6% (5.4%-5.8%)) while women from the least deprived areas were more likely to be prescribed contraceptive pills (20.8% (21.1%-21.5%) vs 26.2% (26.5%-26.9%)). In 2009, LARC prescriptions increased irrespective of age and social deprivation in line with a pay-for-performance incentive. However, following the incentive's withdrawal in 2014, LARC prescriptions for adolescents aged 15-19 years fell from 6.8% (6.6%-7.0%) in 2013 to 5.6% (5.4%-5.8%) in 2018. CONCLUSIONS: CHC prescribing fell by 46% while POP prescribing more than doubled. The type of contraception prescribed was influenced by social deprivation. Withdrawal of a pay-for-performance incentive may have adversely affected adolescent LARC uptake, highlighting the need for further intervention to target this at-risk group

Antibiotic prescribing frequency amongst patients in primary care: a cohort study using electronic health records

BACKGROUND: Reducing inappropriate antibiotic prescribing in primary care is a public health priority. Objectives: We hypothesized that a subset of patients account for the majority of antibiotic prescriptions in primary care. We investigated the relationship between the total amount of antibiotics prescribed, individual-level antibiotic use and comorbidity. METHODS: This was a cohort study using electronic health records from 1 948 390 adults registered with 385 primary care practices in the UK in 2011-13. We estimated the average number of antibiotic prescriptions per patient and the association between prescribing and comorbidity. We modelled the impact on total prescribing of reducing antibiotic use in those prescribed antibiotics most frequently. RESULTS: On average 30.1% (586 194/1 948 390) of patients were prescribed at least one antibiotic per year. Nine percent (174 602/1 948 390) of patients were prescribed 53% (2 091 496/3 922 732) of the total amount of antibiotics, each of whom received at least five antibiotic prescriptions over 3 years. The presence of any comorbidity increased the prescribing rate by 44% [adjusted incidence rate ratio (IRR) 1.44, 95% CI 1.43-1.45]; rates of prescribing to women exceeded those in men by 62% (adjusted IRR 1.62, 95% CI 1.62-1.63). CONCLUSIONS: Half of antibiotics prescribed to adults in primary care were for <10% of patients. Efforts to tackle antimicrobial resistance should consider the impact of this on total prescribing

Costs of vitamin D testing and prescribing among children in primary care

Vitamin D has attracted considerable interest in recent years, with a marked increase in diagnosis of vitamin D deficiency seen among children in clinical practice in the UK. The economic implications of this change in diagnostic behaviour have not been explored. We performed a cohort study to examine longitudinal trends in healthcare expenditure arising from vitamin D testing and prescribing for children in primary care in England, using the electronic healthcare records of 722,525 children aged 0–17 years held in The Health Improvement Network database. Combined costs of vitamin D tests and prescriptions increased from £1647 per 100,000 person-years in 2008 (95% CI, £934 to £3007) to £28,913 per 100,000 person-years in 2014 (95% CI, £26,361 to £31,739). The total cost of vitamin D prescriptions and tests for children in primary care at the national level in England in 2014 was estimated to be £4.31 million (95% CI, £2.96–£6.48 million). CONCLUSION: There has been a marked increase in healthcare expenditure on vitamin D tests and prescriptions for children in primary care over the past decade. Future research should explore the drivers for this change in diagnostic behaviour and the reasons prompting investigation of vitamin D status in clinical practice

Use of contraceptives and risk of inflammatory bowel disease: A nested case–control study

Background: How contraceptive formulation, dose, duration of therapy and mode of delivery affects the risk of inflammatory bowel disease (IBD) is poorly described. // Aim: To examine associations between types of hormonal contraception and development of IBD. // Methods: This was a nested case–control study using IQVIA Medical Research Data. Women aged 15-49 years with a new diagnosis of IBD were matched with up to six controls by age, practice and year. Odds ratios (OR) and 95% confidence intervals (95% CI) for incident IBD and use of contraception were calculated. // Results: 4932 incident cases of IBD were matched to 29 340 controls. Use of combined oral contraceptive pills (COCPs) was associated with the development of Crohn's disease and ulcerative colitis (OR 1.60 [1.41-1.82] and 1.30 [1.15-1.45], respectively). Each additional month of COCP exposure per year of follow-up increased risk of Crohn's disease by 6.4% (5.1%-7.7%) and ulcerative colitis by 3.3% (2.1%-4.4%). Progestogen-only pills had no effect on Crohn's disease risk (OR 1.09 [0.84-1.40]) but there was a modest association with ulcerative colitis (OR 1.35 [1.12-1.64]). Parenteral contraception was not associated with the development of Crohn's disease or ulcerative colitis (OR 1.15 [0.99-1.47] and 1.17 [0.98-1.39], respectively). // Conclusions: We observed an increase in the risk of IBD with increasing duration of exposure to COCPs. Progestogen-only pills were not associated with Crohn's disease but there was a modest association with ulcerative colitis. There was no association between parenteral progestogen-only contraception and IBD. These findings are broadly consistent with a hypothesis that the oestrogen component of contraception may drive IBD pathogenesis

Use of strategies to improve retention in primary care randomised trials: a qualitative study with in-depth interviews

Objective To explore the strategies used to improve retention in primary care randomised trials.&lt;p&gt;&lt;/p&gt; Design Qualitative in-depth interviews and thematic analysis.&lt;p&gt;&lt;/p&gt; Participants 29 UK primary care chief and principal investigators, trial managers and research nurses.&lt;p&gt;&lt;/p&gt; Methods In-depth face-to-face interviews.&lt;p&gt;&lt;/p&gt; Results Primary care researchers use incentive and communication strategies to improve retention in trials, but were unsure of their effect. Small monetary incentives were used to increase response to postal questionnaires. Non-monetary incentives were used although there was scepticism about the impact of these on retention. Nurses routinely used telephone communication to encourage participants to return for trial follow-up. Trial managers used first class post, shorter questionnaires and improved questionnaire designs with the aim of improving questionnaire response. Interviewees thought an open trial design could lead to biased results and were negative about using behavioural strategies to improve retention. There was consensus among the interviewees that effective communication and rapport with participants, participant altruism, respect for participant's time, flexibility of trial personnel and appointment schedules and trial information improve retention. Interviewees noted particular challenges with retention in mental health trials and those involving teenagers.&lt;p&gt;&lt;/p&gt; Conclusions The findings of this qualitative study have allowed us to reflect on research practice around retention and highlight a gap between such practice and current evidence. Interviewees describe acting from experience without evidence from the literature, which supports the use of small monetary incentives to improve the questionnaire response. No such evidence exists for non-monetary incentives or first class post, use of which may need reconsideration. An exploration of barriers and facilitators to retention in other research contexts may be justified.&lt;p&gt;&lt;/p&gt

Incidence, age at diagnosis and survival with dementia across ethnic groups in England: A longitudinal study using electronic health records.

INTRODUCTION: We investigated the incidence of diagnosed dementia and whether age at diagnosis and survival afterward differs among the United Kingdom's three largest ethnic groups. METHODS: We used primary care electronic health records, linked Hospital Episode Statistics and mortality data for adults aged ≥65 years. We compared recorded dementia incidence 1997-2018, age at diagnosis, survival time and age at death after diagnosis in White, South Asian, and Black people. RESULTS: Dementia incidence was higher in Black people (incidence rate ratios [IRR] 1.22, 95% CI 1.15-1.30). South Asian and Black people with dementia had a younger age of death than White participants (mean difference for South Asian participants -2.97 years, (95% CI -3.41 to -2.53); and Black participants -2.66 years, (95% CI -3.08 to -2.24). DISCUSSION: South Asian and Black peoples' younger age of diagnosis and death means targeted prevention and care strategies for these groups should be prioritized and tailored to facilitate take-up

Incidence and prevalence of inflammatory bowel disease in UK primary care: a population-based cohort study

OBJECTIVES: We describe temporal trends in the recorded incidence of inflammatory bowel disease (IBD) in UK primary care patients between 2000 and 2018. DESIGN: A cohort study. SETTING: The IQVIA Medical Research data (IMRD) primary care database. PARTICIPANTS: All individuals registered with general practices contributing to IMRD during the period 01 January 2000-31 December 2018. MAIN OUTCOME MEASURES: The primary outcome was the recorded diagnosis of IBD. RESULTS: 11 325 025 individuals were included and 65 700 IBD cases were identified, of which 22 560 were incident diagnoses made during the study period. Overall, there were 8077 incident cases of Crohn's disease (CD) and 12 369 incident cases of ulcerative colitis (UC). Crude incidence estimates of 'IBD overall', CD and UC were 28.6 (28.2 to 28.9), 10.2 (10.0 to 10.5) and 15.7 (15.4 to 15.9)/100 000 person years, respectively. No change in IBD incidence was observed for adults aged 17-40 years and children aged 0-9 years. However, for adults aged over 40 years, incidence fell from 37.8 (34.5 to 41.4) to 23.6 (21.3 to 26.0)/100 000 person years (average decrease 2.3% (1.9 to 2.7)/year (p<0.0001)). In adolescents aged 10-16 years, incidence rose from 13.1 (8.4 to 19.5) to 25.4 (19.5 to 32.4)/100 000 person years (average increase 3.0% (1.7 to 4.3)/year (p<0.0001)). Point prevalence estimates on 31 December 2018 for IBD overall, CD and UC were 725, 276 and 397 per 100 000 people, respectively. CONCLUSIONS: This is one of the largest studies ever undertaken to investigate trends in IBD epidemiology. Although we observed stable or falling incidence of IBD in adults, our results are consistent with some of the highest reported global incidence and prevalence rates for IBD, with a 94% rise in incidence in adolescents. Further investigation is required to understand the aetiological drivers
