- OBJECTIVE: To investigate whether one additional educational session about inhaler use, delivered to patients with COPD in primary healthcare, could affect the patients' skills in inhaler use. Specifically, to study the effects on errors related to handling the device, to inhalation technique, and to both.METHODS: This nonrandomized controlled clinical trial included 64 patients who used devices and made errors. COPD nurses assessed inhaler use using a checklist and educated patients. Intervention group received one additional educational session after two weeks.RESULTS: At baseline, patients in the IG had more devices (n = 2,1) compared to patients in the CG (n = 1,6) (p = 0.003). No other statistically significant differences were seen at baseline. At follow-up, intervention group showed a lower proportion of patients who made errors related to handling the device (p = 0.006). No differences were seen in the other categories.CONCLUSION: One additional educational session in inhaler use for patients with COPD was effective in reducing the proportion of patients making errors related to handling of their devices.PRACTICE IMPLICATIONS: Categorization of errors might help healthcare professionals to assess the suitability of patients' devices, tailor patient education, and thus improve patient health.

- Spirometry should be used to confirm a diagnosis of chronic obstructive pulmonary disease (COPD). This test is not always performed, leading to possible misdiagnosis. We investigated whether the proportion of patients with diagnostic spirometry has increased over time as well as factors associated with omitted or incorrectly interpreted spirometry. Data from medical reviews and a questionnaire from primary and secondary care patients with a doctors' diagnosis of COPD between 2004 and 2010 were collected. Data were compared with a COPD cohort diagnosed between 2000 and 2003. Among 703 patients with a first diagnosis of COPD between 2004 and 2010, 88% had a diagnostic spirometry, compared with 59% (p < 0.001) in the previous cohort. Factors associated with not having diagnostic spirometry were current smoking (OR 2.21; 95% CI 1.36-3.60), low educational level (OR 1.81; 1.09-3.02) and management in primary care (OR 2.28; 1.02-5.14). The correct interpretation of spirometry results increased (75% vs 82%; p = 0.010). Among patients with a repeated spirometry, 94% had a persistent FEV1/FVC or FEV1/VC ratio <0.70.

Tidskriftsartikel (refereegranskat)abstract
- Background Blood neutrophil-to-lymphocyte ratio (NLR) and blood eosinophils (B-Eos) are emerging biomarkers in COPD. This study examined whether they could predict acute exacerbations of COPD (AECOPDs), and determined their longitudinal stability.Methods In this closed cohort study, Swedish subjects with spirometry-verified COPD attended three yearly visits in a stable phase of the disease. Blood cell counts, spirometry and questionnaire-assessed AECOPD-history (worsening of COPD leading to an unscheduled visit and/or use of antibiotics and/or oral corticosteroids) were collected at each visit.Results Of 466 included subjects 57% were female. Baseline mean±sd forced expiratory volume in 1 s was 58±17% predicted. High NLR (≥3.0) was more common in subjects with previous AECOPDs than in those without (33.5% versus 20.4%, p=0.002). In two-level mixed-effects logistic regression models adjusted for confounders, NLR as a continuous variable (OR 1.20, 95% CI 1.04–1.38) and B-Eos ≥300 cells·µL−1 (OR 1.54, 95% CI 1.06–2.24) were associated with future AECOPDs. In 386 subjects with blood cell data available at all three visits, the intraclass correlation coefficient for NLR was 0.61 (95% CI 0.56–0.66) and for B-Eos 0.69 (95% CI 0.64–0.73). NLR was persistently ≥3.0 in 10.6% and B-Eos was persistently ≥300 cells·µL−1 in 15.3%.Conclusions Stable phase NLR and B-Eos were associated with future AECOPDs. NLR on its own is probably not useful to predict AECOPDs but might be included in a risk scoring index. A minority of subjects with COPD had persistently elevated stable-phase NLR or B-Eos, and the biomarkers showed fair longitudinal reliability.

Alveolar Nitric Oxide in Chronic Obstructive Pulmonary Disease-A Two-Year Follow-Up
- 2022
-
Ingår i: Biomedicines. - : MDPI. - 2227-9059. ; 10:9

Tidskriftsartikel (refereegranskat)abstract
- Chronic obstructive pulmonary disease (COPD) affects the airways and gas exchange areas. Nitric oxide (NO) production from the airways is presented as FENO50 and from the gas exchange areas as alveolar NO (CANO). We aimed to evaluate, over two years, the consistency of the CANO estimations in subjects with COPD. A total of 110 subjects (45 men) who completed the study were included from primary and secondary care settings. CANO was estimated using the two-compartment model. CANO increased slightly during the two-year follow-up (p = 0.01), but FENO50 remained unchanged (p = 0.24). Among the subjects with a low CANO (<1 ppb) at inclusion, only 2% remained at a low level. For those at a high level (>2 ppb), 29% remained so. The modified Medical Research Council dyspnoea scale (mMRC) score increased at least one point in 29% of the subjects, and those subjects also increased in CANO from 0.9 (0.5, 2.1) ppb to 1.8 (1.1, 2.3) ppb, p = 0.015. We conclude that alveolar NO increased slightly over two years, together with a small decline in lung function. The increase in CANO was found especially in those whose levels of dyspnoea increased over time.

Changes in critical inhaler technique errors in inhaled COPD treatment : A one-year follow-up study in Sweden
- 2022
-
Ingår i: Respiratory Medicine. - : Elsevier. - 0954-6111 .- 1532-3064. ; 197

Tidskriftsartikel (refereegranskat)abstract
- Background: Critical inhaler technique errors have been associated with lower treatment efficacy in chronic obstructive pulmonary disease (COPD). We aimed to assess and follow-up critical inhaler technique errors, and to investigate their association with COPD symptoms and exacerbations.Methods: COPD-diagnosed primary and secondary care outpatients (n = 310) demonstrated inhaler technique with inhaler devices they were currently using. Critical errors in opening, positioning and loading the inhaler device, and exhalation through dry-powder inhalers were assessed and corrected, and the assessment was repeated one year later. COPD Assessment Test, the modified Medical Research Council dyspnoea scale and history of exacerbations were collected at both visits.Results: The proportion of patients making >1 critical inhaler technique error was lower at follow-up in the total population (46% vs 37%, p = 0.01) and among patients with unchanged device models (46% vs 35%, p = 0.02), but not among patients with a new inhaler device model (46% vs 41%, p = 0.56). Not positioning the device correctly was the most common critical error at both visits (30% and 22%). Seventy-four percent of the patients had unchanged COPD treatment from baseline to follow-up. Treatment escalation, de-escalation, and switch was observed in 14%, 11%, and 1% of the patients, respectively. No association was found between critical errors and COPD symptoms or exacerbations.Conclusions: Assessment and correction of inhaler technique was associated with a decrease in critical inhaler technique errors. This effect was most pronounced in patients using the same device models throughout the follow-up period.

Critical inhaler technique errors in Swedish patients with COPD : a cross-sectional study analysing video-recorded demonstrations
- 2021
-
Ingår i: npj Primary Care Respiratory Medicine. - : Springer Nature. - 2055-1010. ; 31:1
-
Tidskriftsartikel (refereegranskat)abstract
- A correct use of inhaler devices is essential in chronic obstructive pulmonary disease (COPD) treatment. Critical errors were studied by analysing 659 video-recorded demonstrations of inhaler technique from 364 COPD patients using six different inhaler device models. The majority of the included patients used two (55%) or more (20%) device models. Overall, 66% of the patients made ≥1 critical error with at least one device model. The corresponding numbers for patients using 1, 2 and ≥3 device models were 43%, 70% and 86%, respectively. The only factor associated with making ≥1 critical error was simultaneous use of two (adjusted odds ratios (aOR) 3.17, 95% confidence interval (95% CI) 1.81, 5.64) or three or more (aOR 8.97, 95% CI 3.93, 22.1) device models. In conclusion, the proportion of patients making critical errors in inhaler technique was substantial, particularly in those using several different device models. To obtain optimal COPD treatment, it is important to assess a patient's inhaler technique and to minimise the number of inhaler device models.

Prioritising primary care respiratory research needs : results from the 2020 International Primary Care Respiratory Group (IPCRG) global e-Delphi exercise
- 2022
-
Ingår i: npj Primary Care Respiratory Medicine. - : Springer Nature. - 2055-1010. ; 32:1

Tidskriftsartikel (refereegranskat)abstract
- Respiratory diseases remain a significant cause of global morbidity and mortality and primary care plays a central role in their prevention, diagnosis and management. An e-Delphi process was employed to identify and prioritise the current respiratory research needs of primary care health professionals worldwide. One hundred and twelve community-based physicians, nurses and other healthcare professionals from 27 high-, middle- and low-income countries suggested 608 initial research questions, reduced after evidence review by 27 academic experts to 176 questions covering diagnosis, management, monitoring, self-management and prognosis of asthma, COPD and other respiratory conditions (including infections, lung cancer, tobacco control, sleep apnoea). Forty-nine questions reached 80% consensus for importance. Cross-cutting themes identified were: a need for more effective training of primary care clinicians; evidence and guidelines specifically relevant to primary care, adaption for local and low-resource settings; empowerment of patients to improve self-management; and the role of the multidisciplinary healthcare team.

Prediction of Mortality Using Different COPD Risk Assessments : A 12-Year Follow-Up
- 2021
-
Ingår i: The International Journal of Chronic Obstructive Pulmonary Disease. - : Dove Medical Press Ltd.. - 1176-9106 .- 1178-2005. ; 16, s. 665-675

Tidskriftsartikel (refereegranskat)abstract
- Purpose: A multidimensional approach in the risk assessment of chronic obstructive pulmonary disease (COPD) is preferable. The aim of this study is to compare the prognostic ability for mortality by different COPD assessment systems; spirometric staging, classification by GOLD 2011, GOLD 2017, the age, dyspnea, obstruction (ADO) and the dyspnea, obstruction, smoking, exacerbation (DOSE) indices.Patients and Methods: A total of 490 patients diagnosed with COPD were recruited from primary and secondary care in central Sweden in 2005. The cohort was followed until 2017. Data for categorization using the different assessment systems were obtained through questionnaire data from 2005 and medical record reviews between 2000 and 2003. Kaplan-Meier survival analyses and Cox proportional hazard models were used to assess mortality risk. Receiver operating characteristic curves estimated areas under the curve (AUC) to evaluate each assessment systems´ ability to predict mortality.Results: By the end of follow-up, 49% of the patients were deceased. The mortality rate was higher for patients categorized as stage 3-4, GOLD D in both GOLD classifications and those with a DOSE score above 4 and ADO score above 8. The ADO index was most accurate for predicting mortality, AUC 0.79 (95% CI 0.75-0.83) for all-cause mortality and 0.80 (95% CI 0.75-0.85) for respiratory mortality. The AUC values for stages 1-4, GOLD 2011, GOLD 2017 and DOSE index were 0.73, 0.66, 0.63 and 0.69, respectively, for all-cause mortality.Conclusion: All of the risk assessment systems predict mortality. The ADO index was in this study the best predictor and could be a helpful tool in COPD risk assessment.
