This study shows that adequately trained and supported community pharmacists can effectively identify individuals at high risk of having COPD and can thus contribute to ameliorate underdiagnosis in this disease. Links between PC and CP should be improved to achieve a useful program.

Abstract:Objective: Primary care provides the main route for access to health care for patients with common chronic illnesses such as chronic obstructive pulmonary disease (COPD). Alpha-1 antitrypsin (AAT) deficiency is an underdiagnosed pathology associated with COPD risk which has a very low prevalence. The Information and Detection of the Deficiency of AAT (IDDEA) project was developed to identify AAT-deficient patients at primary care centres by providing adequate diagnostic tools to family doctors. Methods: Patients with COPD were identified and registered on a specially designed website. Dried blood samples were collected on filter papers and sent to the laboratory for AAT levels and AAT deficiency-related genotype determinations. Results were uploaded to the website and analysed. Results: Between January 2008 and April 2009, 596 patients were identified by 90 participating physicians. The number of patients who did not have AAT deficiency (serum concentrations 60 mg AAT/dl) was 549 (98.9%). Nineteen patients (3.2%) were carriers of the allelic variant Pi*Z among which two were homozygous PiZZ (one of them was an index case) and one was heterozygous PiSZ. These three newly detected cases were registered in the Spanish Registry of Patients with AAT Deficiency. An estimate of the gene frequency of the S allele was 7.65% and the severe deficiency Z allele was 1.76%. Conclusions: Results confirm that ATT deficiency is still underdiagnosed. The IDDEA system appears to be a useful tool for the detection of AAT deficiency in the primary care setting.

Study Objectives: Involvement of primary care teams in the care of patients with OSA is a focus of interest. The study objective was to compare diagnostic and therapeutic agreement between decisions taken by primary care professionals and sleep unit specialists. Methods: This was a prospective multicenter study conducted at primary care and specialized care centers in the urban area of Barcelona, Spain. Men and women aged 18-75 years who visited the participating primary care centers for any reason were recruited. Both primary care physicians and sleep specialists made a diagnostic and therapeutic decision with clinical data and results of a home sleep apnea test. All patients were finally assessed with respiratory polygraphy or polysomnography as a gold-standard test. Results: A total of 229 patients underwent a home sleep apnea test and were evaluated at the primary care centers and the sleep units. Diagnostic agreement using the same tools and excluding indeterminate decisions was 69.8% (Cohen's kappa = 0.64; 95% confidence interval, 0.56-0.72). Agreement for therapeutic decisions (PAP vs conservative treatment) was obtained in 82.5% of patients (Cohen's kappa = 0.62; 95% confidence interval, 0.51-0.73), increasing to 92.5% (Cohen's kappa = 0.49, 95% confidence interval, 0.40-0.58) when indeterminate options were excluded. As compared with the final therapeutic decisions made at the sleep unit with respiratory polygraphy/polysomnography, primary care physicians agreed regarding 83.3% (Cohen's kappa = 0.62; 95% confidence interval, 0.49-0.74) of patients. Conclusions: Primary care professionals may assume an important role in the management of OSA in coordination with sleep centers, identifying patients who require specific treatment and should be referred to specialized care.
