Effect of Inhaler Technique Health Education in Improving Symptoms and Lung Function in COPD Outpatient in a Private Hospital in Gresik, Indonesia: Pilot Studies

Inhalers are the most effective therapy in the treatment of Chronic obstructive pulmonary disease (COPD). Research shows that a large number of COPD patients do not use inhalers properly. Incorrect inhaler use technique can reduce drug delivery and poor disease control. Education on how to use inhalers is an important part of COPD management. The study was conducted to determine the effect of education on symptom assessment, lung function assessment and inhaler use skill assessment in COPD patients. The research was in the form of a pre-experimental one-group pre-test post-test. The results showed that there was a significant difference in the effect of education on how to use the inhaler on the assessment of symptoms (p = 0.000), a significant difference in the assessment of lung function (p = 0.001) and a significant difference in the assessment of skills in using the inhaler (p = 0.000). Education on how to use inhalers has an influence on the assessment of symptoms, lung function and skills in using inhalers in COPD patients.

Development of Inhaled Tuberculosis Microparticle using Polysaccharide Polymers Containing Rifamycin Groups: In-vitro and In-vivo Study

Tuberculosis (TB) is one of the urgent global health problems. TB therapy involves the use of antibiotics, but unwanted side effects often accompany the treatment of TB with high doses and long periods of time. In an effort to increase the effectiveness of TB treatment and reduce side effects, direct drug delivery to the lungs is the focus of research. One of the approaches used is the development of drug delivery systems that use natural polymers in dry powder inhalation (DPI) formulations. Natural polymers, especially polysaccharides, have various advantages, such as biodegradability, biocompatibility and non-toxicity. This review discusses the use of rifamycin microparticle tuberculosis inhalation using polysaccharide polymers and reviews relevant in-vitro and in-vivo studies. The use of natural polymers, especially polysaccharides, is expected to increase the efficiency of TB therapy by reducing drug doses and systemic side effects and increasing direct drug delivery to infected organs.

Maintenance Inhalers for Asthma and COPD in Spain.

This study aimed to describe the use of pressurized metered-dose inhalers (pMDIs) and dry powder inhalers (DPIs) in Spanish subjects in terms of sociodemographic, clinical, and functional characteristics in subjects with asthma or COPD on maintenance treatment with inhaled therapy. This was a retrospective, descriptive, national, multi-center, and observational study using a database with 1.8 million patients from hospitals and primary care centers as a secondary information source. The sample included 24,102 subjects with asthma on maintenance therapy (26.0% with pMDI, 55% with DPI, and 19.0% with a combination of DPI + pMDI inhalers) and 12,858 subjects with COPD on maintenance therapy (26% with pMDI; 39% with DPI; and 35% with a combination of pMDI + DPI inhalers, mostly extemporary triple therapy). In proportion, subjects ≥ 75 y old used more pMDI than DPI, while younger subjects (40-64 y old) used more DPI. An inhalation chamber was prescribed in 51.0% of subjects with asthma and 47.2% of subjects with COPD treated with pMDI. The use of an inhalation chamber increases with the degree of air-flow limitation by disease and age. In subjects with comorbidities, pMDI inhaler use increased in those ≥ 75 y old for subjects with asthma and subjects with COPD. Switching from pMDI to DPI and vice versa was relatively common: 25% of subjects with asthma and 21.6% of subjects with COPD treated with pMDI had switched from DPI in the previous year. On the contrary, 14.1% and 11.4% of subjects with asthma and subjects with COPD, respectively, treated with DPI had switched from pMDI the last year. The use of pMDI or DPI can vary according to age, both in asthma and COPD. Switching from pMDI to DPI and vice versa is relatively common. Despite the availability of dual- and triple-therapy inhalers on the market, a considerable number of subjects were treated with multiple devices.

Preventive activities of a nurse when caring for patients with bronchial asthma. Participation in asthma school

Bronchial asthma is a common disease of an allergic nature, often occurring in a mild form. In real clinical practice, patients, due to limited knowledge, do not always provide self-control over the symptoms of the disease. The nurse›s task is to teach the patient basic self-control skills. This is largely facilitated by the participation of medical workers in the asthma school. In most cases, improper use of inhalers and discontinuation of basic therapy with inhaled glucocorticosteroids leads to deterioration of control, despite the satisfactory general condition of the patients. As a result of inadequate control, patients lead a more passive lifestyle, reduce daily physical activity, and gradually reduce or abandon sports and other active activities. The article clearly demonstrates the importance of asthma school in ensuring a high level of control over asthma, in real clinical practice, the formation of effective tactics and strategies for asthma treatment thanks to the personal participation of the patient.

Younger Children with Respiratory Tract Infections Are More Exposed to Off-Label Treatments: An Exploratory Retrospective Study in a Pediatric Emergency Setting.

We performed a retrospective data analysis. All patients aged 0-18 referred to PED from 1 September to 1 October 2022, were included. Further analysis was performed when respiratory tract infections were diagnosed. gender, age, triage group, chronic diseases, vital signs, and PED-prescribed treatment (medications, dosages, methods of administration). Statistical analysis used SPSS 28.0, with significance at p < 0.05. Data from 473 patients were analyzed, median age 3.5 years. Chronic diseases were present in 17.1% of children. 387 medications were prescribed, 47.5% being off-label. Off-label treatment was common for external otitis, acute laryngitis, and acute bronchitis (p < 0.001). There was incorrect administration of tobramycin with dexamethasone for otitis (n = 16, 100%) and inappropriate use of salbutamol inhalations by age (34.8%, n = 16). Some medications were given orally instead of injections (ondansetron n = 5, 62.5%; dexamethasone n = 82, 98.7%) or intranasally instead of intravenously (IV) (midazolam n = 7, 87.5%). IV adrenalin was prescribed for inhalations (n = 46). Younger children were more likely to receive off-label treatment (p < 0.001). Our study highlights the widespread issue of off-label and unlicensed drug prescribing in pediatric emergency care. Further research is necessary, because this reliance on off-label prescribing raises concerns about patient safety and compliance, especially given the limited clinical trials and therapeutic options available.

APPaRENT 3: Asthma Patients' and Physicians' Perspectives on the Burden and Management of Asthma in Seven Countries.

Asthma management is strongly dependent on physician and patient beliefs and perceptions about the disease and its long-term treatment. The APPaRENT 3 study was conducted to explore factors influencing treatment choice and to understand patients' and physicians' attitudes and perspectives on the use of controller inhalers in regular versus flexible dosing for asthma management. This cross-sectional survey of patients with asthma and treating physicians was conducted in seven countries: Indonesia, Malaysia, Philippines, Thailand, Vietnam (patient survey only), Saudi Arabia, and the United Arab Emirates. Assessment was carried out through an online/face-to-face questionnaire, where patients' viewpoints were focused on their attitudes and beliefs about asthma and treatment adherence, whereas physicians' viewpoints were gathered on their attitudes and beliefs about asthma management, knowledge of and adherence to asthma treatment guidelines, and asthma treatment regimens. Overall, 1400 patients (mean age, 34years) and 599 physicians (mean age, 43years) were included in the survey. Physicians similarly prioritised symptom control (39%) and exacerbation reduction (40%) in moderate asthma, whereas patients prioritised symptom control (41%) over exacerbation reduction (22%). Although both groups (physicians, 86%; patients, 84%) perceived asthma as well-controlled, poor management was evident based on Asthma Control Test (ACT) scores (mean, 15.7; standard deviation, 4.14; 82% had an ACT score<20) and high symptom burden (39% reported nighttime awakenings or early mornings≥2 nights/week). Most patients (76%) with moderate asthma were prescribed regular dosing, with the most common treatment being inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA) with as-needed inhaled short-acting β2-agonist (SABA; 20%). Among patients on maintenance and reliever therapy, 93% of patients received a separate inhaled reliever. Despite high symptom burden, patients overestimated their level of asthma control. Physicians prioritised controlling symptoms and reducing exacerbations as treatment goals for moderate asthma, often prescribing regular dosing with ICS/LABA with as-needed inhaled SABA.

Improvement in Inhaler Techniques After Training and Counseling in Patients With Chronic Obstructive Pulmonary Disease or Asthma.

Background Chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma significantly impair quality of life and impose a substantial burden on healthcare systems. Proper inhalation technique is important for effective management of these diseases, yet remains poorly performed by many patients. This study evaluated the impact of structured counseling and training sessions on inhaler use among patients with COPD and asthma, aiming to enhance technique correctness and disease control. Methodology This cross-sectional study analyzed 150 patients with asthma and COPD who fulfilled the inclusion criteria for inhalation techniques. Patients were counseled regarding the proper seven-step inhalation technique for each inhaler type [metered-dose inhaler (MDI), MDI with spacer, and dry powder inhaler (DPI)] through practical demonstration at baseline visits. Correct use of inhalers was assessed by a predefined checklist for each inhaler device at the baseline visit and after three months. The correctness of the inhalation technique was evaluated by scoring each of the seven steps. The disease control assessment was done using the COPD assessment test (CAT) and asthma control test (ACT) at the baseline visit and after three months. Results In this study of 150 patients, there were 97 (64.7%) males and 53 (35.3%) females. In total, 67 (44.7%) were diagnosed with asthma and 83 (55.3%) with COPD. The mean age was 45.33 ± 12.62 years. Post-counseling improvements in inhaler technique were marked, with MDI users enhancing their technique score from an average of 4.4 to 6.1, MDI with spacer from 4.56 to 6.26, and DPI from 4.92 to 6.24 (p < 0.001 for all). Disease control also showed significant gains; CAT scores decreased for MDI users from 23.4 to 20.5, MDI with spacer from 23.92 to 20.96, and DPI from 24.89 to 21.96. Concurrently, ACT scores increased for MDI users from 16.4 to 18.0 (p = 0.002), MDI with spacer from 17.29 to 19.04, and DPI from 16.42 to 18.37 (p < 0.001 for both), reflecting substantive advances in managing COPD and asthma symptoms. Furthermore, patients with primary education exhibited a significant boost in technique mastery post-counseling (p < 0.001), underscoring the potential of well-crafted counseling to transcend educational barriers in promoting effective inhaler use. Conclusions Post-counseling, inhaler technique improved significantly across all types, with MDI with spacer users demonstrating the most progress. Technique scores increased notably (p < 0.001), and disease control scores for COPD and asthma, measured by CAT and ACT, also showed significant improvements (p < 0.001). Remarkably, primary education level participants exhibited substantial technique gains post-intervention, emphasizing the effectiveness of counseling irrespective of initial educational status in enhancing inhaler use and disease management.

Features of pain sensitivity during premedication with xenon in patients before outpatient dental interventions

BACKGROUND: Premedication in outpatient dental interventions normalizes pain sensitivity and emotional state of patients. Inhalation of xenon-oxygen mixture can be an effective means for it. AIM: To study the effect of xenon premedication on pain sensitivity in patients with outpatient dental interventions. MATERIALS AND METHODS: Twenty patients were studied. Emotional and personal characteristics of patients were determined using the Eysenck test, Spielberger–Khanin personal anxiety scale, and hospital scale of anxiety and depression. Pain sensitivity was assessed using pain thresholds and somatosensory evoked potentials of the brain before and after inhalation of xenon-oxygen mixture at a concentration of 30/70 for 3 minutes. RESULTS: According to the results of psychological testing, all examined patients were characterized by a stable psychological sphere and predominantly lowered anxiety and constituted a group with insignificantly different emotional and personal characteristics. Before inhalation, pain sensitivity in patients varied significantly. After inhalation, multidirectional changes in pain sensitivity occurred, which were expressed in a decrease and an increase in pain sensitivity thresholds and the degree of activation of brain structures. CONCLUSION: Preoperative stress can both exacerbate and reduce pain sensitivity in patients. The use of inhalation of a xenon-oxygen mixture at a concentration of 30/70 for 3 minutes as a premedication causes multidirectional changes in the sensitivity of tissues and organs in the maxillofacial region in patients before outpatient dental interventions, which may be caused by a change in the activity of endogenous antinociceptive (analgesic) system.

Rate of Correct Inhaler Usage and Related Factors in Elderly Patients With Chronic Obstructive Pulmonary Disease

Poor disease control in patients with chronic obstructive pulmonary disease (COPD) is associated with suboptimal inhaler use. This study was designed to explore the accuracy of inhaler use and related factors in elderly patients with COPD. A cross-sectional survey design was used to recruit patients with COPD from a medical centre in southern Taiwan who were over 65 years old and used inhalers regularly. All of the data as well as information on inhaler use accuracy were collected using a self-designed questionnaire and inhaler operation checklist. Multivariable logistic regression was used to analyse significant correlates of correct inhaler operation. The average age of the 150 participants was 75.0 years (SD = 7.5) years. Most used one type of inhaler only (86.0%). The rate of accurate inhaler operation was 40.7% (n = 61) for the sample, with dry powder inhalers associated with the highest accuracy (64%) and pressurized metered-dose inhalers associated with the lowest accuracy (1.6%). Multivariate logistic regression analysis showed that using a soft mist inhaler (adjusted odds ratio, AOR = 23.29; 95% confidence interval, 95% CI [2.84, 191.07]), using a dry powder inhaler (AOR =15.60, 95% CI [1.99, 122.26]), and higher satisfaction with the inhaler were positively and independently associated with accurate inhaler use (AOR = 1.94, 95% CI [1.09, 3.44]). Important factors related to inhaler use accuracy include inhaler type and level of patient satisfaction with their inhaler. Healthcare professionals should regularly confirm that older patients are able to use their inhalers correctly and are satisfied with their inhalers.

Climate-conscious inhaler prescribing for family physicians.

To provide family physicians with prescribing and diagnostic strategies that can reduce carbon emissions associated with inhalers. This review is based on the authors' experience developing the climate-conscious inhaler prescribing playbooks and courses for CASCADES (Creating a Sustainable Canadian Health System in a Climate Crisis). The approach was refined through patient and provider feedback since the first playbook was published in 2021. PubMed was also searched for relevant publications on inhaler use, asthma management, and chronic obstructive pulmonary disease (COPD) management. Current asthma and COPD guidelines were also reviewed. There is growing acknowledgment of the substantial impact that inhalers have on climate emissions generated by the health sector. Recent surveys indicate that most Canadian patients care about climate change and would be willing to opt for less carbon-intensive treatment and care delivery options where available. Beyond inhaler choice, there are many opportunities to address the climate impacts of respiratory care and enhance quality of care. Working with patients to ensure they are using the right medications in the right ways will produce both carbon savings and better health outcomes. The climate crisis can therefore serve as a catalyst for improving treatment of patients with respiratory conditions. Family physicians may reduce carbon emissions associated with inhalers by reducing unnecessary inhaler prescribing; ensuring patients' control of asthma and COPD is optimized; considering whether a more sustainable inhaler may be appropriate; optimizing dosing technique to reduce emissions and waste; and disposing of inhalers appropriately if possible. Family physicians may reduce carbon emissions associated with inhalers through the following strategies: confirming diagnosis, controlling disease, considering inhaler type, optimizing dosing technique, and encouraging appropriate disposal.

Antibacterial Effect of Nitric Oxide on the Causative Agents of Hospital-Acquired Pneumonia (Experimental Study)

The aim of the study was to evaluate the antimicrobial effect of single and repeated nitric oxide (NO) exposure on the major pathogens of nosocomial pneumonia isolated from the sputum of cardiac surgery patients.Materials and Methods. A 24-hour culture of microorganisms from pan-resistant isolates of Pseudomonas aeruginosa, Escherichia coli, Acinetobacter baumannii, and Klebsiella pneumoniae from the sputum of inpatient cardiac surgery patients with nosocomial pneumonia, as well as strains of P. aeruginosa and E. coli from the American Type Culture Collection (ATCC), were exposed to 200 ppm NO (experimental sample) or medical air (control sample) in a sealed chamber for 30 minutes. After a single or 4 repeated gas exposure at 4 h intervals, Petri dishes were placed in a thermostat at 37°C and the results were evaluated at 24 and 48 h or at 12, 24, 36 and 48 h, respectively. Grown colonies were counted using an automated colony counter and recorded as CFU/mL.Results. No growth of clinical isolates of P. aeruginosa and E. coli was observed 24 and 48 h after a single exposure to NO. Growth of A. baumannii was lower compared to controls at 24 h but continued at 48 h. No effect of a single exposure to 200 ppm NO on other microorganisms was observed. After 4 exposures to NO, the growth of ATCC E. coli was not detected, the growth of other experimental strains was significantly lower compared to the control (P&lt;0.05).Conclusion. Our results provide a rationale for the use of multiple intermittent inhalation of 220 ppm NO for the treatment of patients with hospital-acquired bacterial pneumonia.

Association between the consumption of psychoactive substances and suicidal thoughts in school-age adolescents in Colombia 2016

ABSTRACT Background: Suicidal thoughts are a frequent problem in adolescents and young people. They have been associated with psychoactive substances’ consumption.Objective: To determine the prevalence of suicidal thoughts and its association with the psychoactive substances’ consumption during the last 12 months, in school adolescents in Colombia, in 2016 Materials andMethods: A secondary analysis of the information obtained from the 2016 National Study on Consumption of Psychoactive Substances in Colombian. For this, data from 80,018 adolescents, between 12 and 18 years of age were analyzed. Sociodemographic characteristics, suicidal thoughts’ frequency, and consumption of 12 psychoactive substances were examined. Generalized linear models were used to estimate the association between suicidal thought and different psychoactive substance consumption.Results: The prevalence of suicidal thoughts was 15.7%. All psychoactive substances showed association with suicidal thoughts. The association of greater magnitude was registered with the use of non-prescription tranquilizers (OR 3.66 95%CI 3.06 – 4.31), inhalants (OR 3.65 95%CI 3.08 – 4.33), basuco (OR 3.39 95%CI 2.49 – 4.61), cigarettes (OR 2.70 95%CI 2.49 – 2.93), marijuana (OR 2.34 95%CI 2.11 – 2.59), and alcohol (OR 2.29 95%CI 2.13 – 2.48).Conclusions: Suicidal thoughts show association with all psychoactive substances’ consumption, additionally, polydrug use was found to increase the magnitude of the association.

The effect of budesonide-formoterol powder inhalation on cough and lung function following thoracoscopic pulmonary surgery: a retrospective cohort study.

To explore whether portable budesonide-formoterol powder inhalation can ameliorate cough symptoms and improve pulmonary function recovery in patients who underwent thoracoscopic lung surgery. Clinical data of patients who underwent thoracoscopic pulmonary resection at Henan Provincial People's Hospital between December 2022 and May 2023 were extracted. To evaluate the impact of continuous post-operative use of portable budesonide-formoterol powder inhalation, patients were divided into two groups: the control group and the case group. Next, we compared the Leicester cough score and pulmonary function indexes of the patients before surgery, one month and six month after the operation. A total of 188 cases were included, and the baseline demographic characteristics of both groups were well-balanced. The internal consistency of the LCQ-MC scale, as indicated by Cronbach's α coefficients, were all greater than 0.8, and there was no significant difference in LCQ-MC scores between the two groups before the operation (Z=-1.173, P=0.241). Postoperatively, the LCQ-MC score in the case group was significantly higher than that in the control group (18.66 vs. 16.79, P<0.01), with a notable statistically significant difference in the reduction of LCQ-MC scores between the two groups (1.32 vs. 3.30, P<0.01). Analysis of lung function revealed that patients in the case group exhibited significant improvements in FEV1/FVC, FVC, FEV1, PEF, MMEF75/25, MVV, DLCO and the RV/TLC indexes compared to the control group (P<0.01). Portable budesonide-formoterol powder inhalation can alleviate cough symptoms and promote pulmonary function recovery in patients following thoracoscopic lung surgery.

The role of community pharmacists as oral health advisors in the management of oral effects of asthma medications: an exploratory survey.

To investigate community pharmacists' attitudes, confidence, practice, knowledge, and barriers towards the management of oral side effects of asthma medications. A paper-based questionnaire was developed from previous research, trialled, and validated. Convenience sampling through web search was used to identify pharmacy practices across Cairns, Queensland, Australia. Practices were contacted by email and phone before hand-delivering and collecting questionnaires. Thirty eight community pharmacist responses were descriptively analysed. Community pharmacists surveyed within the Cairns region feel that it is within their role to help manage the side effects of asthma medications. Many feel this is best conveyed during inhaler dispensing and instruction. Current advice is more prompted rather than preventative. Pharmacists routinely advise patients of mouth-rinsing following inhaler use, however the link to preventing side effects is not clearly communicated. Pharmacists are confident in recognizing and managing common side effects such as oral thrush and dry mouth, but fewer are aware of dental decay and gingivitis. Many identify a lack of guidelines as the largest barrier to providing preventive oral health advice. Cairns community pharmacists already self-perceive their role in the management of oral side effects of asthma medications. Advice given to patients is practical but does not clearly convey the causative associations between asthma medications and their potential oral side effects. Patient education is prompted more by enquiry rather than a preventative approach. The development of standardized practice protocols and integration within undergraduate degrees or continuing education may benefit the community-pharmacist delivered care.

The Effect of Educational Intervention on Inhaler Technique of Patients in Asian Countries: A Systematic Review

Background: Inhalation therapy is the main line of treatment for the management of various respiratory diseases due to localized delivery and rapid onset of action. Incorrect inhaler technique is very common and subsequently leads to poor disease management. Pharmacist can have a positive impact on patient’s education about proper inhaler technique that can lead to a significant improvement of asthma and COPD management. Objective: The objective of this study was to determine the effectiveness of pharmacist education program on inhaler technique of asthmatic and COPD patients in South Asian countries. The outcome regarding inhalation technique was reviewed and summarized. Methodology: The outcome regarding inhalation technique was reviewed and summarized. For this systematic review, basic electronic academic databases (Scopus, Science Direct, ProQuest, Web of Science and PubMed) were used for the search, along with a manual search on Google Scholar. This systematic review was conducted by following the “Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)” guidelines. Moreover, utilizing the framework of the PECO-S (Population Exposure Comparison Outcome Study design), various observational studies were recruited for this review. The ZEE tool was utilized to minimize the risk of bias among extracted cross-sectional studies. Inclusion criteria included studies on inhaler using patients of all ages from South Asian countries along with the influence of educational intervention outcomes. Results: Out of 2191 studies, 24 studies meeting the inclusion criteria were included in the current review. All of the included studies were about pharmacist intervention on inhaler technique in South Asian countries. Conclusion: The systematic literature review summarizes the impact of educational intervention provided to inhaler using patients from South Asian countries. It was assessed that patient education and counselling produced improvement in inhalation technique of various devices especially metered dose inhalers. The primary outcome of most the studies was the improvement in inhaler technique assessment and enhanced quality of life. Therefore, inhaler technique education to patients should be made compulsory by the Health-care authorities to enhance compliance and effectiveness of inhalational therapy by avoiding irrational use of inhalers.

Inhalant abuse among street-involved children and adolescents in India: Case for epistemic recognition and reorientation.

Contextualizing the void of research on inhalant abuse among adolescents as epistemic neglect, in this study, we use mixed-methods action research to understand inhalant abuse in a specific context in the Global South. Focusing on a large metropolitan city in Western India, we surveyed 158 street-involved children and adolescents (110 boys and 48 girls, age range from 5 to 17 years) in a group setting along with follow-up group interviews. Despite finding a high prevalence rate of inhalant abuse, our work suggests an absence of supporting structures and emphasizes the need to revisit our understanding and interpretation of substance-using behavior of street-involved youth. Instead of explaining inhalant-abusing behavior as emerging from pathological deficiencies in individuals or households, we stress the need to critically examine the exploitative environment they are embedded in. In doing so, we join efforts to decolonize conventional ways of understanding "deviant" behavior.

Pulmonologist Education of the Teach-to-Goal Inhaler Technique for Those With Asthma and COPD.

Inhaler education for patients with asthma and patients with COPD is typically provided by non-pulmonologists. We studied inhaler education by pulmonologists to determine changes in clinical outcomes and inhaler use. This was a retrospective study of 296 subjects diagnosed with asthma, COPD, or both that evaluated use of inhaler technique education and its impact on (1) inhaler/dosage change consisting of dosage change in the same class of inhaler and/or change in number of inhalers, (2) forced expiratory volume in one second/forced vital capacity (FEV1/FVC%), (3) disease symptom control, (4) out-patient visits, (5) urgent care visits (6) emergency department visits, and (7) hospital admissions. One group received inhaler technique education by a pulmonologist while the other group did not. The pulmonologist inhaler technique-educated group had significantly decreased relative risk for inhaler/dosage increase (relative risk 0.57 [95% CI 0.34-0.96], P = .03) and significantly increased odds for symptom control (odds ratio 2.15 [95% CI 1.24-3.74], P = .01) at 1-y follow-up as compared to the no education group. No differences occurred for FEV1/FVC%, out-patient visits, urgent care visits, emergency department visits, and hospital admissions. Pulmonologist education of inhaler technique for patients with asthma and patients with COPD was associated with decreased relative risk for inhaler/dosage increase and increased odds for symptom control. We recommend pulmonologists provide education of inhaler technique to patients with asthma and patients with COPD and not rely on non-pulmonologist education alone. Prospective research is needed to confirm the importance of proper inhaler techniques.

Patients’ views and behaviours in relation to asthma inhalers use and their impact on environmental sustainability: a cross-sectional survey study

Abstract Introduction Approximately 60 million inhalers are used annually in England, contributing 3% to the National Health Service (NHS) carbon footprint. Of these, 2 out of 3 are metered-dose inhalers (MDIs) containing greenhouse gas propellants.[1] The carbon footprint of an MDI device is around 500g CO2 equivalent, in contrast with the 20g CO2 equivalent of a dry powder inhaler (DPI).[2] The NHS Long Term Plan introduced measures on environmental sustainability, leading to the National Institute of Health Care and Excellence (NICE) launching a ‘shared decision aid’ to promote the discussion of options for inhaler devices. This landmark policy step could be more effective if received with patient support and informed behaviours of patients with regard to inhalers. Research is therefore needed to identify patients’ views and behaviours on this matter. Aim To identify patients’ views and behaviours related to environmental sustainability aspects of their use of inhalers for the management of asthma. Methods An anonymous self-completion paper-based questionnaire was administered to patients with a clinical diagnosis of asthma. These were recruited opportunistically via 10 community pharmacies in the South of England during the month of February 2020. They were provided information about the study and invited to participate by pharmacy staff when collecting prescriptions. Participants had to be prescribed at least one MDI inhaler and not to be using a DPI, and report on the use, disposal and views regarding their environmental impact. Responses to the questionnaire were coded and analysed using descriptive statistics. Results A total of 149 surveys were completed by patients, of which 47% (n=70) were male and 53% (n=79) were female. The age range of respondents varied with the majority 45.6% being 18-29 years old, followed by 21.5% in the 60-69 years category. Of these, 30.2% (n=48) were aware of MDI inhalers having an impact on carbon footprint, and 53% (n=79) on plastic pollution. A majority (81%) of patients stated that they were involved or partially involved in their inhaler choice. Only 62% (n=92) said they would be willing to switch their MDI to a more environmentally friendly inhaler with equal effectiveness, 15.4% (n=23) reported they would not be willing to do so and 22.1% (n=33) were not sure. Unwanted inhalers were returned by 43% (n=64) of participants for appropriate disposal, with 55% (n=82) of respondents being unaware of this option. A majority (91%, n=136) of participants said they would like further information about their inhalers and their impact on the environment. Conclusion There is scope for a more environmentally friendly management of asthma and the use of inhalers. Healthcare professionals are involving patients in decision making when prescribing, and pharmacists could contribute to this when dispensing. Patients would welcome information on the impact of inhalers on the environment and further research could identify more precisely on what aspects, alongside barriers preventing a switch to more environmentally friendly options. A small sample size and geographical area were limitations of this study, which could be overcome by further researching issues identified in this survey.

Chronic Serous Chorioretinopathy: A Case Study

Introduction Chronic central serous chorioretinopathy (CSCR) is characterized by persistent subretinal fluid that disrupts the outer layers of the retina and may lead to complications such as: outer retinal atrophy, increased risk of choroidal neovascularization (CNVM) and the potential for permanent vision loss. This report describes the clinical features of chronic CSCR. Case Presentation A 73-year-old male with a history of systemic steroid and inhaler use presented for a routine eye exam without visual complaints. Examination findings included normal visual acuity in both eyes and multiple areas of retinal hyper and hypopigmentation along the arcades with no macular involvement in the right eye; the left eye was unremarkable. Fundus photography and optical coherence tomography showed localized areas of outer retinal disruption and thinning near the optic nerve head and along the corresponding retinal areas of irregular pigmentation in the right eye; the left eye was unremarkable. Discussion In chronic CSCR, structural changes in the retina can lead to retinal dysfunction and permanent vision loss. Treatment options for chronic CSCR include photodynamic therapy, intravitreal anti-vascular endothelial growth factor therapy, or systemic steroid receptor blockers. Visual prognosis varies depending on the severity of the disease, age of onset, risk of CNVM and the degree of outer retinal degeneration. Conclusion Patients with chronic CSCR are at risk for permanent vision loss. The structural changes in the outer retina also increase the risk for CNVM. Hence, it is important that patients with chronic CSR receive regular eye examinations and are educated on the role of regular Amsler grid testing.
