The recording and characteristics of pulmonary rehabilitation in patients with COPD using The Health Information Network (THIN) primary care database.

Pulmonary rehabilitation is recommended for patients with COPD to improve physical function, breathlessness and quality of life. Using The Health Information Network (THIN) primary care database in UK, we compared the demographic and clinical parameters of patients with COPD in relation to coding of pulmonary rehabilitation, and to investigate whether there is a survival benefit from pulmonary rehabilitation. We identified patients with COPD, diagnosed from 2004 and extracted information on demographics, pulmonary rehabilitation and clinical parameters using the relevant Read codes. Thirty six thousand one hundred and eighty nine patients diagnosed with COPD were included with a mean (SD) age of 67 (11) years, 53% were male and only 9.8% had a code related to either being assessed, referred, or completing pulmonary rehabilitation ever. Younger age at diagnosis, better socioeconomic status, worse dyspnoea score, current smoking, and higher comorbidities level are more likely to have a record of pulmonary rehabilitation. Of those with a recorded MRC of 3 or worse, only 2057 (21%) had a code of pulmonary rehabilitation. Survival analysis revealed that patients with coding for pulmonary rehabilitation were 22% (95% CI 0.69-0.88) less likely to die than those who had no coding. In UK THIN records, a substantial proportion of eligible patients with COPD have not had a coded pulmonary rehabilitation record. Survival was improved in those with PR record but coding for other COPD treatments were also better in this group. GP practices need to improve the coding for PR to highlight any unmet need locally. CHRONIC LUNG DISEASE: ROLLING OUT THE REHAB: Analysis of recent UK data suggests that more patients with chronic lung disease could benefit from lung rehabilitation programmes. During pulmonary rehabilitation (PR), patients with chronic obstructive pulmonary disease (COPD) work with specialists to learn exercises and optimise breathing techniques. The programmes are recommended under current guidelines, particularly for patients with a high breathlessness score. Despite this, when Charlotte Bolton and co-workers at the University of Nottingham analysed 36,189 patient primary care records gathered since 2004, they found only 9.8% of COPD patients had ever had a coded record of being assessed, referred for, or undertaken PR. Those patients who completed PR were 22% less likely to die that those who didn't, although appeared they had also received better overall COPD care. Current smokers, those suffering from co-morbidities and younger patients were more likely to receive PR than other patient groups.

What characteristics of primary care and patients are associated with early death in patients with lung cancer in the UK?

BACKGROUND: The UK has poor lung cancer survival rates and high early mortality, compared to other countries. We aimed to identify factors associated with early death, and features of primary care that might contribute to late diagnosis. METHODS: All cases of lung cancer diagnosed between 2000 and 2013 were extracted from The Health Improvement Network database. Patients who died within 90 days of diagnosis were compared with those who survived longer. Standardised chest X-ray (CXR) and lung cancer rates were calculated for each practice. RESULTS: Of 20,142 people with lung cancer, those who died early consulted with primary care more frequently prediagnosis. Individual factors associated with early death were male sex (OR 1.17; 95% CI 1.10 to 1.24), current smoking (OR 1.43; 95% CI 1.28 to 1.61), increasing age (OR 1.80; 95% CI 1.62 to 1.99 for age ≥80 years compared to 65-69 years), social deprivation (OR 1.16; 95% CI 1.04 to 1.30 for Townsend quintile 5 vs 1) and rural versus urban residence (OR 1.22; 95% CI 1.06 to 1.41). CXR rates varied widely, and the odds of early death were highest in the practices which requested more CXRs. Lung cancer incidence at practice level did not affect early deaths. CONCLUSIONS: Patients who die early from lung cancer are interacting with primary care prediagnosis, suggesting potentially missed opportunities to identify them earlier. A general increase in CXR requests may not improve survival; rather, a more timely and appropriate targeting of this investigation using risk assessment tools needs further assessment.

First trimester exposure to anxiolytic and hypnotic drugs and the risks of major congenital anomalies: a United Kingdom population-based cohort study.

BACKGROUND: Despite their widespread use the effects of taking benzodiazepines and non-benzodiazepine hypnotics during pregnancy on the risk of major congenital anomaly (MCA) are uncertain. The objectives were to estimate absolute and relative risks of MCAs in children exposed to specific anxiolytic and hypnotic drugs taken in the first trimester of pregnancy, compared with children of mothers with depression and/or anxiety but not treated with medication and children of mothers without diagnosed mental illness during pregnancy. METHODS: We identified singleton children born to women aged 15-45 years between 1990 and 2010 from a large United Kingdom primary care database. We calculated absolute risks of MCAs for children with first trimester exposures of different anxiolytic and hypnotic drugs and used logistic regression with a generalised estimating equation to compare risks adjusted for year of childbirth, maternal age, smoking, body mass index, and socioeconomic status. RESULTS: Overall MCA prevalence was 2.7% in 1,159 children of mothers prescribed diazepam, 2.9% in 379 children with temazepam, 2.5% in 406 children with zopiclone, and 2.7% in 19,193 children whose mothers had diagnosed depression and/or anxiety but no first trimester drug exposures. When compared with 2.7% in 351,785 children with no diagnosed depression/anxiety nor medication use, the adjusted odds ratios were 1.02 (99% confidence interval 0.63-1.64) for diazepam, 1.07 (0.49-2.37) for temazepam, 0.96 (0.42-2.20) for zopiclone and 1.27 (0.43-3.75) for other anxiolytic/hypnotic drugs and 1.01 (0.90-1.14) for un-medicated depression/anxiety. Risks of system-specific MCAs were generally similar in children exposed and not exposed to such medications. CONCLUSIONS: We found no evidence for an increase in MCAs in children exposed to benzodiazepines and non-benzodiazepine hypnotics in the first trimester of pregnancy. These findings suggest that prescription of these drugs during early pregnancy may be safe in terms of MCA risk, but findings from other studies are required before safety can be confirmed.

The impact of the United Kingdom's national smoking cessation strategy on quit attempts and use of cessation services: findings from the International Tobacco Control Four Country Survey.

INTRODUCTION: The World Health Organization Framework Convention on Tobacco Control recommends that provision of cessation support should be included in national tobacco control strategies. This study examines the impact of the United Kingdom's national smoking cessation strategy on quit attempts, use of treatment and short-term abstinence, relative to the United States, Canada, and Australia where less support is provided. METHODS: Data on quitting behavior and use of support were obtained for all smokers enrolled in the International Tobacco Control 4 Country Survey between 2002 and 2005. Generalized estimating equations were used to calculate the relative odds (adjusted by age, sex, and Heaviness of Smoking Index) that smokers in each country made quit attempts, used behavioral or pharmacological support, and to compare rates of short-term (28 days) abstinence between countries and users of different forms of support. RESULTS: U.K. smokers were less likely to have attempted to quit smoking than those in Australia (odds ratio [OR] = 1.25, 95% CI: 1.12-1.40), Canada (OR = 1.50, 95% CI: 1.34-1.67), and the United States (OR = 1.25, 95% CI: 1.11-1.40) but were more likely to use pharmacotherapy and/or support from a clinic, helpline, or health professional when attempting to quit than smokers in the other countries. U.K. smokers making quit attempts were significantly more likely to achieve 28-day abstinence than those in Australia (OR = 0.59, 95% CI: 0.49-0.71), Canada (OR = 0.72, 95% CI: 0.61-0.87), and the United States (OR = 0.51, 95% CI: 0.42-0.62). CONCLUSIONS: U.K. smokers report fewer quit attempts but are more likely to use support when quitting and to achieve short-term abstinence.

Prevalence of major comorbidities in subjects with COPD and incidence of myocardial infarction and stroke: a comprehensive analysis using data from primary care.

BACKGROUND: Comorbidities associated with systemic inflammation including cardiovascular disease (CVD), stroke and diabetes mellitus (DM) are common among individuals with chronic obstructive pulmonary disease (COPD). A study was undertaken to quantify the burden of comorbidity and to determine the risk of first acute arteriovascular events among individuals with COPD. METHODS: The computerised primary care records of 1,204,100 members of the general population aged ≥ 35 years on 25 February 2005 were searched for recordings of each disease. Data were analysed using multivariate logistic regression. Cox regression was used to determine whether individuals with COPD were at increased risk of acute myocardial infarction (MI) and stroke. RESULTS: Cross-sectional analyses showed that physician-diagnosed COPD was associated with increased risks of CVD (OR 4.98, 95% CI 4.85 to 5.81; p<0.001), stroke (OR 3.34, 95% CI 3.21 to 3.48; p<0.001) and DM (OR 2.04, 95% CI 1.97 to 2.12; p<0.001). In the follow-up analyses, after adjusting for confounding by sex and smoking status and stratifying for age, the greatest increase in the rate of acute arteriovascular events was found in the youngest age groups; the HR for acute MI was 10.34 (95% CI 3.28 to 32.60; p<0.001) and for stroke the HR was 3.44 (95% CI 0.85 to 13.84; p<0.001) compared with the oldest age group. CONCLUSION: Individuals with COPD are substantially more likely to have pre-existing CVD, DM or a previous stroke and are at high risk of acute arteriovascular events. National COPD guidelines and models of care need to adapt to provide an integrated approach to addressing these comorbidities.
