The Air We Breathe…Early Detection of Small Airway Disease in Poultry Production Farmers
Submitted by: Rose-Marie Dolinar RN (EC) PhD, Health & Rehabilitation Sciences, The Universtiy of Western Ontario
Chronic Obstructive Pulmonary Disease (COPD) is preventable and treatable.
The Global Initiative for Chronic Obstructive Lung Disease (GOLD) (1) states that COPD is “characterized by persistent respiratory symptoms and airflow limitation that is due to airway and/or alveolar abnormalities usually caused by significant exposure to noxious particles or gases.” The Global Initiative for Chronic Obstructive Lung Disease further explains the variable nature of COPD as a mixture of small airway disease (e.g., obstructive bronchiolitis) and parenchymal destruction (emphysema), and that both conditions vary from person to person (2).
Volgemeir et al. (2017) summarized the changes in the 2017 GOLD diagnostic and treatment recommendations, which now include both spirometry and symptom evaluations (3). Since COPD encompasses both small airway and terminal airway diseases of chronic bronchitis and emphysema, using both spirometry and a standardized lung health questionnaire provides a more comprehensive picture of each person’s lung health, especially for those at high risk of developing chronic obstructive lung diseases.
Patients with ongoing symptoms of cough and phlegm are not being diagnosed according to a Canadian study. The range of undetected COPD is between 25 and 50% of patients with COPD symptoms and risk factors (4) (5). According to Hill, Goldstein, Guyatt et al. (2010), as many as one in five adults with known risk factors for COPD who meet spirometric criteria are not diagnosed for COPD (5). Under-diagnosis of COPD suggests a need for greater screening of at-risk individuals.
Persons at Risk for COPD
Persons at highest risk for developing COPD are those who smoke cigarettes, with a 25% prevalence of moderate to severe COPD for both men and women equally (6). Although cigarette smoking is a major risk factor, occupational health studies indicate that more than 15% of all cases of COPD are work-related (7).
Poultry Farmers Lung Health Study
This study is the result of a meeting held in January 2015 between poultry farmers and a lung health researcher to discuss concerns of the poultry farmers regarding lung health in the workplace. Following approval, obtained from the Health Sciences Research Ethics Board at the University of Western Ontario (protocol #107685), the Poultry Producers Lung Health Study was launched.
The study’s aim was to promote and protect the lung health of poultry farmers. Results of the N95 Respirator Fit-testing outreach article have been published in the 2018 Winter edition of Update. This article will report the measurement of lung health of poultry farmers, which included the spirometry and lung health symptoms and MD-confirmed diagnostic findings.
The study design was a cohort observational study with a convenience sample, based on the available two-day lung health clinic appointments. Two clinic days were available for the pilot study due to health centre booking and resource availability, as well as timing of harvest for the farmers. Participants were required to meet the following inclusion criteria: a poultry farmer 40 years of age or older who is fluent in English and has a family physician or health-care provider for ongoing medical care. Those who did not have a doctor were excluded from the study since reports of the spirometry were sent to each of the participant’s health-care provider for follow-up care.
Measuring Lung Symptoms
The standardized American Thoracic Society (ATS) Lung Health Questionnaire (LHQ) from the Division of Lung Diseases (DLD) of the National Heart, Lung, and Blood Institute, ATS-DLD78 (9), was administered to all participants. The Medical Research Council (MRC) Breathlessness Scale, which grades breathlessness related to exercise and activity, was included in the ATS-DLD78 with the following grading scale: Grade 1 Not troubled by breathlessness except on strenuous exercise; Grade 2 Short of breath when hurrying on the level or walking up a slight hill; Grade 3 Walks slower than most people on the level, stops after a mile or so, or stops after 15 minutes walking at own pace; Grade 4 Stops for breath after walking about 100 yards or after a few minutes on level ground; and Grade 5 Too breathless to leave the house, or breathless when undressing (8).
Measuring Lung Function
Pre/post bronchodilator spirometry was performed using the National Health and Nutrition Examination Survey (NHANES III) Hankinson et al. (1999) standard reference prediction equations (9). A certified Registered Respiratory Therapist (RRT) performed all the pre/post spirometry according to Canadian Thoracic Society guidelines (10). Interpretation of the pre/post spirometry were based on GOLD 2017 (1) and D’Urzo (2011) (11) spirometry interpretation logarithms for the identification of COPD and asthma. Chronic obstructive pulmonary disease diagnostic criteria included the post-bronchodilator forced expiratory volume in one second (FEV1) and the forced vital capacity (FVC) ratio (FEV1/FVC) of less than 0.70 (<0.70), and asthma was defined as an improvement in FEV1 of 12% or over, and 200 mL after the bronchodilator challenge.
The Forced Expiratory Flow between 25 and 75% of the FVC (FEF25–75) is one of the most commonly cited measures of small airways pathology (13). The reasons that tests of small airways such as FEF 25-75% have not been utilized as part of lung function measurement include variability in test results and a lack of validated reference ranges (13). However, the FEF 25-75% was included to ensure the pre/post spirometry was able to capture any changes in both large airways and small airways of the lungs.
Independent Data Collection
Each participant’s spirometry lung function was performed independently from the Lung Health Questionnaire (LHQ) administration. Results were compared as blinded since LHQ and spirometry data were collected separately.
Two rural lung health clinics were held in Seaforth, Ontario and Clinton, Ontario on August 3rd and August 4th, 2016, respectively, to fit within harvest times for the participants.
A total of 16 poultry farmers (N=16) participated in the study. The average age of participants was 56.8 years (SD 9.74), with 82% males and 18% females.
Farm dust exposure, in numbers of years, was reported by all 16 participants with an average of 38 years (SD 14.95). Smoking status was reported as current smoker, within the last month, never smoked, or an ex-smoker for the past month. Duration of smoking was calculated by the standard measure of pack years (one pack year equivalent to 20 cigarettes per day) for one year.
Table 1: Cigarette Smoking (n=16)
|Current smokers||1/16 (6.25%)|
|Never smoked||8/16 (50%)|
|Pack years||5.07 (SD 6.93)|
The lung health questionnaire asked if the participant had a doctor who confirmed the presence of bronchitis, emphysema and asthma. The answers to the presence of MD-confirmed lung diseases provided an independent evaluation. There were no reports of MD-confirmed emphysema. However, three participants reported that their physicians confirmed chronic bronchitis, and two participants reported confirmation of asthma.

|Cough and phlegm||3/16|
(MRC grade 3,4,5)
Table 3: Results of MD-confirmed lung disease
|MD-confirmed lung condition||Result (n=16)|
Sixteen (16) pre/post spirometry tests were performed and interpreted. Upon reviewing the results of the de-identified pre/post spirometry data, two spirometry results were excluded, one as it identified a pre-existing lung health condition, and the other showed non-reproducible manoeuvres. Fourteen (14) spirometry results were included in the grouped data.
All fourteen (14) post bronchodiolator FEV1/FVC ratios were above 70%. There were no results meeting FEV1 criteria for a spirometric diagnosis of asthma, as none of the 14 spirometry results showed an improvement in FEV1 of 12% or over, and 200 mL after bronchodilator.
Four of the results of post FEV1/FVC ratios were between 70 and 75%, with three approaching COPD criteria. These same four spirometry results demonstrated post FEF 25-75% reductions from predicted (between -12% and -22%), whereas all other spirometry results had no reductions in the mid-range FEF 25-75% small airway region.
Comparison of Symptoms, MD-confirmed Diagnoses and Spirometry Results
When comparing the lung health questionnaire data to the spirometry results, the participants with symptoms of cough and phlegm, and MD-confirmed diagnosis of chronic bronchitis, matched the reduced FEV1/FVC results between 70 and 75%. The post FEV1/FVC results also matched the reductions of the FEF 25-75% results.
The poultry producers’ lung health study included both pre/post spirometry and a standardized questionnaire to gather symptoms and screen for early detection of lung disease.
Results indicated that symptoms of cough and phlegm and MD-confirmed bronchitis matched FEV1/FVC ratios between 70% and 75%. According to McDonough et al. (2011), as bronchitis becomes more widespread over time, more of the small airways (<2 mm in diameter) become affected (12).
The study found that participants smoked an average of five pack years, equivalent to 20 cigarettes per day for 5 years. The average age of the poultry farmers was 56 years of age). Although individual susceptibility for the development of COPD varies, there is no minimum number of pack years which would put one person at greater risk for COPD (15).
Results of the pre/post spirometry confirmed a relationship between symptoms of chronic bronchitis and the spirometry results between 70 and 75%. The results of the post FEF 25-75% may be an important indicator to report for agricultural workers. With early detection of small airway disease, there is a potential for reversal of early stages of COPD (16).
These results point to the need for lung health screening through ongoing lung health clinics for those at high risk for developing COPD.
Lung health monitoring through standardized questionnaires and pre/post spirometry is recommended for poultry farmers. Physician-confirmed presence of bronchitis matched the presence of reduced post-FEV1/FVC spirometry and FEF 25-75% (n=14), indicating early detection of small airway disease. Future studies are required to support the use of both standardized measures.
Respiratory care health professionals, including RRTs, physicians and nurses, providing care to farmers are needed to provide screening for early signs of lung disease through pre/post bronchodilator spirometry, to be able to prevent the development of COPD.
Occupational exposure to dusts, chemicals, and gases found in poultry farming are risk factors for developing COPD (7) (14). The implications of occupational lung exposures in contributing to a diagnosis of COPD must be considered in research planning, in public policy decision-making, and in clinical practice.

Innovative Care for the COPD Patient in a Rural Community Hospital
Submitted by: E. Annette Stuart, RRT, CRE, CTE, Lennox & Addington County General Hospital
BREATHE….it sounds so simple. In the respiratory profession, we know that the mechanics and the execution of breathing is a big challenge for our patients with Chronic Obstructive Pulmonary Disease (COPD). With increasing focus on COPD and the associated costs of managing this disease in health care, the South East Local Health Integration Network (SELHIN) organized a regional respiratory focus group comprised of community agencies, patient advocate representatives, hospital staff and physicians to address the gaps associated with the care of a COPD patient. This “think tank” aimed to identify ways to reduce hospital readmission rates, frequent emergency room (ER) visits and the incidence of respiratory exacerbations associated with COPD. Using the lessons learned at the regional level, the Lennox & Addington County General Hospital (LACGH) in Napanee implemented its own innovative program for COPD patients in the local community. As a result, our program goals have been met while helping patients dealing with COPD achieve improved quality of life, greater independence and an increase in self-confidence. I would like to introduce our BREATHE program.
In an effort to model the excellent work already done in Canada, such as that of Dr. Graeme Rocker in Halifax with the INSPIRED project, we examined our hospital’s discharge strategy for COPD patients exhibiting a level of 4 or 5 on the Medical Research Council (MRC) dyspnea scale and identified an opportunity to improve the inpatient education and discharge process. We developed a Pre-Discharge COPD Order Set to address care delivery process issues in areas such as spirometry, medication optimization and inhaler technique, COPD action plans, weight management and exercise, smoking cessation, support for difficult emotions related to chronic disease, advanced care planning and ongoing support after discharge from hospital. Each patient receives a checklist to ensure all aspects related to COPD management are addressed prior to discharge. A drop in Breathe Clinic was established for those instances where patients were unable to receive all the necessary information prior to discharge due to short admission times or even the patient’s ability to cope with influx of information. The Breathe Clinic is staffed by a Registered Respiratory Therapist (RRT) and a Nurse Practitioner (NP) on a regular basis and an Internal Medicine Specialist on an as needed basis.
Pulmonary rehabilitation was another challenge that needed to be addressed for all COPD patients as the two available programs in the area had extensive wait lists. The Quality Based Procedures for COPD, as set out by Health Quality Ontario, indicates that access to an exercise program within 4-6 weeks of discharge from hospital due to an acute exacerbation of COPD is one of the key components to ensure respiratory health success. To pool our resources, we aligned with our Cardiac Rehabilitation program since many cardiac patients have co-morbid respiratory disease and assimilated COPD patients into the existing exercise program to enable our hospital to offer Respiratory Rehabilitation. With that need addressed, the last piece of the puzzle required for a successful comprehensive program was access to care after discharge through community outreach. Although a BREATHE Help Line existed, the benefit of a physical visit to assess the patient could not be fully achieved within the confines of a phone call.
In our geographical area many patients live in remote communities and are isolated due to limited access to transportation, financial constraints or minimal family support. For various reasons, many of our patients are unable to accommodate frequent travel to hospital or clinic follow-up visits. Even those patients that are not geographically isolated may have limited access to services simply based on the extreme challenges associated with shortness of breath.
Our Chief of Staff at LACGH found a possible solution for this problem when she attended the e-Health conference in 2017, where she connected with a virtual health program provider. The possibility of doing follow-up clinic visits and monitoring through technology that could break down the barrier of access for many of our patients was realized. LACGH invested in the virtual health technology and began using it with discharged COPD patients in the BREATHE program in January 2018. The virtual health program allows us to monitor oxygen saturations, heart rate, blood pressure and weight remotely and visualize trends over time. It also allows us to “push” information to patients through reminders regarding medication adherence, signs of a lung flare-up, shortness of breath levels, and breathing techniques to name a few. The patient is able to call the RRT or NP during regular work hours to address any questions they might have regarding management of their COPD. No longer will the patient be required to travel to the BREATHE clinic appointments at the hospital. Clinic visits are scheduled via the virtual health program. This provides the health-care professional a visual of how the patient is doing, their respiratory pattern, use of accessory muscles, skin colour and also opportunity of ongoing education as it provides ability to assess patient management. We can also determine if the patient is experiencing the symptoms of an exacerbation and educate them to refer to their COPD action plan and provide guidance to access their primary care provider(PCP) for management. If the PCP is not available, the NP or Internal Medicine Specialist will provide the prescriptions necessary to manage and control the exacerbation. The other significant benefit from this virtual program is the involvement of family and caregivers. They can participate in the virtual monitoring with their loved one and also connect with the BREATHE program team should they have concerns. It provides a continuum in the circle of care for the patient.
Twenty-three patients have been enrolled since the inception of the BREATHE program. We have prevented 13 re-admissions to hospital by helping the patient manage their symptoms at home. Although not all re-admissions can be prevented, we have seen a decrease in frequency from those enrolled in the program. Patients enrolled in the virtual program have saved the time and cost associated with more than 4,000 km’s in travel to attend the hospital, clinic or ER. Typically, patients stay connected through the virtual program for about three months and once they are well established in the management of their COPD, they rely less on the program and more on their own newly developed self-management skills. They have ongoing access to the BREATHE clinic and the BREATHE Help Line. Patients are also regularly participating in respiratory rehabilitation or an exercise program in their community. Patient and family feedback has been positive and has encouraged LACGH to continue with all aspects of the BREATHE program.
To improve the lives of patients living with COPD in our area we implemented 3 innovative strategies, a Pre-Discharge COPD Order Set, a combined Cardiac-Pulmonary Rehabilitation Program and a virtual health technology service to link the Breathe Clinic to the patient’s home. Ultimately, our goal was to ensure patients received the knowledge and COPD management skills to permit a reduction in our hospital readmission rate. In the end we also gained an appreciation for the benefits of creating a system where the patient feels they can control their COPD rather than being at the mercy of their symptoms, be more confident in their ability to manage their condition and enjoy an improved quality of life.
Patient-and-Family centered performance measures focused on actionable processes of care for persistent or chronic critical illness.
Submitted by Louise Rose, RN, BN, ICU Cert, MN, PhD, FAAN
Advances in technology and adoption of efficacious interventions into clinical practice have improved intensive care unit (ICU) survival rates. However, approximately 10% of critically ill adults experience persistent or chronic critical illness. This results in protracted ICU length of stay, ongoing dependency on resource-intensive therapies, and long-term physical and cognitive deficits, complicating and prolonging recovery.
Family members of these patients also experience enormous emotional distress. Patients with persistent or chronic critical illness have unique and complex needs requiring a change in the clinical management plan and overall goals of care to a focus on rehabilitation, symptom relief, and in some cases, end-of-life care. Existing ICU care quality and tools, such as daily rounding checklists, are not sufficiently inclusive of actionable processes of care (i.e., care we can change) appropriate to patients with persistent or chronic critical illness. Further, these measures or tools have not been developed with the patient and family perspectives at the forefront. Our project, partly funded by the Ontario Respiratory Care Society/The Lung Association, will address this gap by identifying care priorities and developing a tool to help us deliver care to improve the ICU experience for these patients and their family members.
In this project we will answer the following research questions:
- What does the evidence base tell us about actionable processes of care for patients with persistent or chronic critical illness?
- What do survivors of persistent or chronic critical illness and their family recall about their ICU experience that can identify actionable processes of care of importance to them?
- What do ICU clinicians perceive to be important for the delivery of high-quality care to these patients and their family members?
- Which processes of care and outcomes are prioritized by key stakeholders including survivors of persistent or chronic critical illness, their family members, and the clinicians that treat them?
To answer these research questions, we have completed a systematic review of published evidence relating to our population of interest. This review has produced 36 actionable processes of care of potential relevance. We are now conducting narrative-based, loosely structured video interviews of ICU survivors and family members to help us identify ICU processes of care of importance to them. These interviews will be combined to generate a touch-point video – a research tool that helps identify aspects of care relevant to care recipients. This video will be shown to clinicians. Following, interviews will be conducted with them to identify aspects of care important to clinicians. We then intend to conduct a consensus ranking exercise to identify 8 to 10 actionable processes of care to be embedded into a daily rounding checklist for ICU patients with a length of stay over 7 days. Next steps of our research program will be to determine the feasibility and pilot test implementation of this daily rounding tool. If you know of an ICU survivor or family member that might be interested in participating in an interview or consensus exercise, or if you as a clinician would like to participate, for further information please contact Dr. Louise Rose – firstname.lastname@example.org.
Doing two things at once – Is it more difficult for people living with COPD?
Submitted by Darlene Reid, BMR, PhD
Background – Does multitasking take more brain-power and lead to more mistakes?
Multitasking, such as walking across the street while looking at a cell phone, often results in doing one or both things poorly. People with cognitive impairment have more limitations when multitasking because they do not have the “brain-power” to do more than one activity with complete accuracy. For decades, people with chronic obstructive pulmonary disease (COPD) have been known to have mental challenges with memory and attention. The reported prevalence of cognitive impairment in people with COPD ranges between 36 to 57%.1-3 Research has focused on how cognitive impairment affects mental functions such as memory or attention but has not addressed how limited brain-power affects physical activity like balance and walking in people with COPD.
Walking is usually considered to be fairly automatic but it often requires multitasking because we might be thinking about things while we walk (e.g., talking to a friend or what to buy at the hardware store) or manoeuvring around objects, like frost heaves in the sidewalk or furniture in our home. Recently, impaired balance and greater falls have been reported in people with COPD.4-6 Much work has focused on peripheral issues such as muscle strength, physical performance tasks and cellular attributes of muscle fibres to explain their slow walking and poor balance. However, limited functional mobility may in part be attributed to impairment of brain areas that provide input to movement and balance.
What is our research question?
As a first step to explore the brain’s contribution to multi-tasking, we monitored brain activity during single tasks and combined tasks in people with COPD. We also studied comparison groups of younger adults and an older age-matched healthy cohort. The purpose of our study was to compare dual tasks’ error to single tasks’ error while measuring prefrontal cortex oxygenated haemoglobin as a marker of neural activity in these three groups of participants.
How are we studying the problem?
Brain activity of the prefrontal cortex was evaluated by measuring oxygenated hemoglobin via functional near infrared spectroscopy (fNIRS)7,8 (see picture to the right). Increased neural activity in the prefrontal cortex (front of the brain) increases the metabolic demand of the neurons, which in turn increases blood flow to the brain region and increases the amount of oxygenated haemoglobin. We evaluated neural activity of the prefrontal cortex during walking at the participant’s usual pace and when the person walked as quickly and safely as possible. We also asked the person to spell five-letter words backwards. We then asked the participant to do two things at once – to walk at their usual pace while spelling words backwards and to walk at a very quick pace while spelling words backwards. In addition to monitoring neural activity using fNIRS, we also measured the accuracy of spelling backwards and the variability in walking. We used a Zeno pressure sensitive mat (see picture below) that has ~14,000 sensors. Using the associated software, various measures of gait such as velocity, stride length and variability of these parameters were derived. My Masters student, Ahmed Hassan, has done the majority of the work on this project. He was also assisted by my postdoctoral fellow, Dr. Karina Kasawara, and two visiting scientists, Dr. Leandro Bonetti from Brazil and Dr. Masatoshi Hanada from Japan. Dr. Kara Patterson, a colleague in the Department of Physical Therapy at the University of Toronto, has also provided substantial expert consultation.
What have we discovered?
Our sample sizes are small right now and the study is ongoing so these results are preliminary. We have found that people with COPD make more errors when spelling backwards during walking compared to simply spelling backwards. The number of spelling errors made during dual tasking in COPD participants was greater than those errors made by younger and older adults. They also walk more slowly while spelling backwards compared to walking alone. Lastly, neural activity of the prefrontal cortex increased more during dual versus single tasks in the older group and tended to increase in the COPD participants.
What next? How do we help our patients?
One of the most effective ways to improve the quality of life in people with chronic obstructive lung disease is to improve their fitness. Although people with COPD have a tendency to fall more often than other older adults, the best ways to improve balance and walking ability are not known. Although not all tested in COPD patients, several interventions have the potential to improve mobility while multi-tasking in COPD patients such as virtual reality and complex obstacle training simulations. Even aerobic training can increase cognitive function in the elderly9 so this intervention alone, in our COPD clients, has the potential of improving their function in more complex situations.
