Background: Oral prednisolone is the mainstay treatment for bullous pemphigoid, an auto-immune blistering skin disorder affecting older people. Moderate to high dose treatment is often initiated in secondary care, but then continued in primary care. Aim: To describe long-term oral prednisolone prescribing in UK primary care for adults with bullous pemphigoid 1998-2017. Design and setting: A prospective cohort study using routinely collected data from the Clinical Practice Research Datalink, a primary care database containing the healthcare records for over 17 million people in the UK. Method: Oral prednisolone exposure was characterised in terms of the proportion of individuals with incident bullous pemphigoid prescribed oral prednisolone following their diagnosis and the duration and dose of prednisolone. Results: 2,312 (69.6%) of 3,322 people with bullous pemphigoid were prescribed oral prednisolone in primary care. The median duration of exposure was 10.6 months (IQR 3.4 to 24.0). Of prednisolone users, 71.5% were continuously exposed for >3 months, 39.8% for >1 year, 14.7% for >3 years, 5.0% for >5 years, and 1.7% for >10 years. The median cumulative dose was 2,974mg (IQR 1,059 to 6,456). Maximum daily doses were ≥10mg/day in 74.4% of users, ≥20mg/day in 40.7%, ≥30mg/day in 18.2%, ≥40mg/day in 6.6%, ≥50mg/day in 3.8%, and ≥60mg/day in 1.9%. Conclusions: A high proportion of people with incident bullous pemphigoid are treated with oral prednisolone in UK primary care. Primary and secondary care should address steroid-sparing alternatives and, where switching is not possible, ensure prophylactic treatments and proactive monitoring of potential side-effects are in place.

ObjectivesThe purpose of this study was to estimate the annual incidence of Lyme disease (LD) in the UK.DesignThis was a retrospective descriptive cohort study.SettingStudy data were extracted from the Clinical Practice Research Datalink (CPRD), a primary care database covering about 8% of the population in the UK in 658 primary care practices.ParticipantsCohort of 8.4 million individuals registered with general practitioners with 52.4 million person-years of observation between 1 January 2001 and 31 December 2012.Primary and secondary outcome measuresLD was identified from recorded medical codes, notes indicating LD, laboratory tests and use of specific antibiotics. Annual incidence rates and the estimated total number of LD cases were calculated separately for each UK region.ResultsThe number of cases of LD increased rapidly over the years 2001 to 2012, leading to an estimated incidence rate of 12.1 (95% CI 11.1 to 13.2) per 100 000 individuals per year and a UK total of 7738 LD cases in 2012. LD was detected in every UK region with highest incidence rates and largest number of cases in Scotland followed by South West and South England. If the number of cases has continued to rise since the end of the study period, then the number in the UK in 2019 could be over 8000.ConclusionsThe incidence of LD is about threefold higher than previously estimated, and people are at risk throughout the UK. These results should lead to increased awareness of the need for preventive measures.Trial registration numberThis study was approved by the Independent Scientific Advisory Committee for CPRD research (Protocol number 13_210R).

The Impact

Background: Up to 70% of patients report ongoing symptoms four weeks after hospitalisation for pneumonia, and the impact on primary care is poorly understood. Aim: To investigate the frequency of primary care consultations after hospitalisation for pneumonia, and the reasons for consultation. Design: Population-based cohort study. Setting: UK primary care database of anonymised medical records (Clinical Practice Research Datalink, CPRD) linked to Hospital Episode Statistics (HES), England. Methods: Adults with the first ICD-10 code for pneumonia (J12-J18) recorded in HES between July 2002-June 2017 were included. Primary care consultation within 30 days of discharge was identified as the recording of any medical Read code (excluding administration-related codes) in CPRD. Competing-risks regression analyses were conducted to determine the predictors of consultation and antibiotic use at consultation; death and readmission were competing events. Reasons for consultation were examined. Results: Of 56,396 adults, 55.9% (n=31,542) consulted primary care within 30 days of discharge. The rate of consultation was highest within 7 days (4.7 per 100 person-days). The strongest predictor for consultation was a higher number of primary care consultations in the year prior to index admission (adjusted sHR 8.98, 95% CI 6.42-12.55). The commonest reason for consultation was for a respiratory disorder (40.7%, n=12,840), 12% for pneumonia specifically. At consultation, 31.1% (n=9,823) received further antibiotics. Penicillins (41.6%, n=5,753) and macrolides (21.9%, n=3,029) were the commonest antibiotics prescribed. Conclusion: Following hospitalisation for pneumonia, a significant proportion of patients consulted primary care within 30 days, highlighting the morbidity experienced by patients during recovery from pneumonia.

Background: It is uncertain whether stroke risk of asymptomatic ambulatory atrial fibrillation (AA-AF) incidentally-detected in primary care is comparable with other clinical AF presentations in primary care or hospital. Methods: The stoke risk of 22,035 patients with incident non-valvular AF from the UK primary care Clinical Practice Research Datalink with linkage to hospitalization and mortality data, was compared to 23,605 controls without AF (age and sex-matched 5:1 to 5,409 AA-AF patients). Incident AF included 5,913 with symptomatic ambulatory AF (SA-AF); 4,989 with Primary and 5,724 with non-Primary Hospital AF discharge diagnosis (PH-AF and Non-PH-AF); and 5,409 with AA-AF. Ischemic stroke adjusted subhazard ratios (aSHR) within 3 years of AA-AF were compared with SA-AF, PH-AF, Non-PH-AF and controls, accounting for mortality as competing risk and adjusted for ischemic stroke risk factors. Results: There were 1026 ischemic strokes in 49,544 person-years in patients with incident AF (crude incidence rate 2.1 ischemic strokes/100 person-years). Ischemic stroke aSHR over 3 years showed no differences between AA-AF, and SA-AF, PH-AF and nonPH-AF groups (aSHR 0.87-1.01 vs AA-AF). All AF groups showed a significantly higher aSHR compared to controls. (subhazard rate ratio 0.40 [0.34 - 0.47]. Conclusion: Ischemic stroke risk in patients with AA-AF incidentally-detected in primary care is far from benign, and not less than incident AF presenting clinically in general practice or hospital. This provides justification for identification of previously undetected AF, e.g. by opportunistic screening, and subsequent stroke prevention with thromboprophylaxis, to reduce the approximately 10% of ischemic strokes related to unrecognized AF.

ObjectivesTo compare population-based incidence rates of new-onset depression or self-harm in patients initiating incretin-based therapies with that of sulfonylureas (SU) and other glucose-lowering agents.DesignPopulation-based cohort study.SettingPatients attending primary care practices registered with the UK-based Clinical Practice Research Datalink (CPRD).ParticipantsUsing the UK-based CPRD, we identified two incretin-based therapies cohorts: (1) dipeptidyl peptidase-4 inhibitor (DPP-4i)-cohort, consisting of new users of DPP-4i and SU and (2) glucagon-like peptide-1 receptor agonists (GLP-1RA)-cohort, consisting of new users of GLP-1RA and SU, between January 2007 and January 2016. Patients with a prior history of depression, self-harm and other serious psychiatric conditions were excluded.Main outcome measuresThe primary study outcome comprised a composite of new-onset depression or self-harm. Unadjusted and adjusted Cox proportional hazards regression was used to quantify the association between incretin-based therapies and depression or self-harm. Deciles of High-Dimensional Propensity Scores and concurrent number of glucose-lowering agents were used to adjust for potential confounding.ResultsWe identified new users of 6206 DPP-4i and 22 128 SU in the DPP-4i-cohort, and 501 GLP-1RA and 16 409 SU new users in the GLP-1RA-cohort. The incidence of depression or self-harm was 8.2 vs 11.7 events/1000 person-years in the DPP-4i-cohort and 18.2 vs 13.6 events/1000 person-years in the GLP-1RA-cohort for incretin-based therapies versus SU, respectively. Incretin-based therapies were not associated with an increased or decreased incidence of depression or self-harm compared with SU (DPP-4i-cohort: unadjusted HR 0.70, 95% CI 0.51 to 0.96; adjusted HR 0.80, 95% CI 0.57 to 1.13; GLP-1RA-cohort: unadjusted HR 1.36, 95% CI 0.72 to 2.58; adjusted HR 1.25, 95% CI 0.63 to 2.50). Consistent results were observed for other glucose-lowering comparators including insulin and thiazolidinediones.ConclusionsOur findings suggest that the two incretin-based therapies are not associated with an increased or decreased risk of depression or self-harm.

AbstractObjectivesSepsis is a growing concern for health systems, but the epidemiology of sepsis is poorly characterised. We evaluated sepsis recording across primary care electronic records, hospital episodes and mortality registrations.Methods and FindingsCohort study including 378 general practices in England from Clinical Practice Research Datalink (CPRD) GOLD database from 2002 to 2017 with 36,209,676 patient-years of follow-up with linked Hospital Episode Statistics (HES) and Office for National Statistics (ONS) mortality registrations. Incident sepsis episodes were identified for each source. Concurrent records from different sources were identified and age-standardised and age-specific incidence rates compared. Logistic regression analysis evaluated associations of gender, age-group, fifth of deprivation and period of diagnosis with concurrent sepsis recording.There were 20,206 first episodes of sepsis from primary care, 20,278 from HES and 13,972 from ONS. There were 4,117 (20%) first HES sepsis events and 2,438 (17%) mortality records concurrent with incident primary care sepsis records within 30 days. Concurrent HES and primary care records of sepsis within 30 days before or after first diagnosis were higher at younger or older ages and for patients with the most recent period of diagnosis with those diagnosed during 2007:2011 less likely to have a concurrent HES record given CPRD compared to those diagnosed during 2012 to 2017 (odd ratio 0.65, 95% confidence interval 0.60 to 0.70). At age 85 and older, primary care incidence was 5.22 per 1,000 patient years (95% CI 1.75 to 11.97) in men and 3.55 (0.87 to 9.58) in women which increased to 10.09 (4.86 to 18.51) for men and 7.22 (2.96 to 14.72) for women after inclusion of all three sources.ConclusionExplicit recording of sepsis is inconsistent across healthcare sectors with a high proportion of non-concurrent records. Incidence estimates are higher when linked data are analysed.
