Office-Based Case Finding for Chronic Obstructive Pulmonary Disease in Older Adults in Primary Care

How to Enhance the Diagnosis of Early Stages of Chronic Obstructive Pulmonary Disease (COPD)? The Role of Mobile Spirometry in COPD Screening and Diagnosis-A Systematic Review

COPD is the third leading cause of death worldwide. Its diagnosis can be made with spirometry, which is underused due to its limited accessibility. Portable spirometry holds promise for enhancing the efficacy of COPD diagnoses. The study aimed to estimate COPD prevalence diagnosed with a portable spirometer in high-risk patients and compare it with COPD prevalence based on data from conventional, on-site spirometry. We also evaluated the strategy of a proactive approach to identify COPD in high-risk individuals. We conducted a systematic review of original studies on COPD targeted screening and diagnosis with portable and conventional spirometers selected from 8496 publications initially found in three databases: Cochrane, PubMed, and Embase. The inclusion criteria were met by 28 studies. COPD prevalence evaluated with the use of portable spirometers reached 20.27% and was lower compared to that estimated with the use of conventional spirometers (24.67%). In 11 included studies, postbronchodilator tests were performed with portable spirometers, which enabled a bedside COPD diagnosis. Portable spirometers can be successfully used in COPD targeted screening and diagnosis and thus enhance the detection of COPD at early stages.

Frailty screening in older adults: is annual screening necessary in primary care?

BACKGROUND

The Case-finding for Complex Chronic Conditions in Adults 75+ (C5-75) involves annual frailty screening in primary care using dual-trait screening measures of handgrip strength and gait speed, with additional screening for co-existing conditions in those deemed frail.

OBJECTIVE

To identify low-risk individuals who could be screened for frailty every 2 years, rather than annually.

METHODS

This study examined a prospective cohort of patients who completed at least two annual C5-75 screenings between April 2014 and December 2018. Handgrip strength and gait speed on initial assessment were categorized based on proximity to frailty thresholds and were used to predict frailty risk on the second assessment. We used Fisher's exact test to assess differences in risk. Logistic regression models tested associations between independent variables of age, patient activity level, falls history, grip strength and gait speed on first assessment and dependent variable of frailty on subsequent assessment.

RESULTS

Analyses included 571 patients with two annual assessments. Frailty risk on the second assessment was significantly higher for patients who had gait speed or grip strength within 20% of the frailty threshold (5.7%), compared with the other categories (0.7%, 0.9%, 0%; P = 0.002); 60% of patients fell within these lower risk categories. Controlling for grip strength and gait speed, no other measures had significant associations with frailty risk.

CONCLUSIONS

Our results demonstrate that 60% patients are at low risk (<1%) of transitioning to frailty by the next annual assessment. Reducing screening frequency from annually to every 2 years may be appropriate for these patients.

The C5-75 Program: Meeting the Need for Efficient, Pragmatic Frailty Screening and Management in Primary Care

Case-Finding for Complex Chronic Conditions in Seniors 75+ (C5-75) is a systematic approach to identify frailty using gait speed and hand-grip strength and to screen for co-morbid conditions. We identified the C5-75 features offering the highest yield for identifying frailty and to streamline the screening program. Analyses included 1,948 C5-75 assessments completed from 2013 to 2018. Age 85 or older, less than regular physical activity, and more than two falls in the previous six months had the strongest associations with frailty. Exempting patients under 85 who reported regular physical activity and less than two falls excluded 39.1 per cent of the cohort while maintaining a sensitivity of 95.2 per cent and a negative predictive value of 99.4 per cent for frailty. These findings provide insight into optimizing screening for frailty, making it more feasible to implement and to identify co-existing conditions that may contribute to or be affected by frailty.

Identification and Assessment of Breathlessness in Clinical Practice: A Systematic Review and Narrative Synthesis

CONTEXT

Breathlessness is common in chronic conditions but often goes unidentified by clinicians. It is important to understand how identification and assessment of breathlessness occurs across health care settings, to promote routine outcome assessment and access to treatment.

OBJECTIVE

The objective of this study was to summarize how breathlessness is identified and assessed in adults with chronic conditions across different health care settings.

METHODS

This is a systematic review and descriptive narrative synthesis (PROSPERO registration: CRD42018089782). Searches were conducted on Medline, PsycINFO, Cochrane Library, Embase, and CINAHL (2000-2018) and reference lists. Screening was conducted by two independent reviewers, with access to a third, against inclusion criteria. Data were extracted using a bespoke proforma.

RESULTS

Ninety-seven studies were included, conducted in primary care (n = 9), secondary care (n = 53), and specialist palliative care (n = 35). Twenty-five measures of identification and 41 measures of assessment of breathlessness were used. Primary and secondary care used a range of measures to assess breathlessness severity, cause, and impact for people with chronic obstructive pulmonary disease. Specialist palliative care used measures assessing broader symptom severity and function with less focus on overall quality of life. Few studies were identified from primary care.

CONCLUSION

Various measures were identified, reflective of the setting's purpose. However, this highlights missed opportunities for breathlessness management across settings; primary care is particularly well placed to diagnose and support breathlessness. The chronic obstructive pulmonary disease approach (where symptoms and quality of life are part of disease management) could apply to other conditions. Better documentation of holistic patient-reported measures may drive service improvement in specialist palliative care.

Frailty Screening and Case-Finding for Complex Chronic Conditions in Older Adults in Primary Care

With the aging population, escalating demand for seniors' care and limited specialist resources, new care delivery models are needed to improve capacity for primary health care for older adults. This paper describes the "C5-75" (Case-finding for Complex Chronic Conditions in Seniors 75+) program, an innovative care model aimed at identifying frailty and commonly associated geriatric conditions among older adults within a Canadian family practice setting and targeting interventions for identified conditions using a feasible, systematic, evidence-informed multi-disciplinary approach. We screen annually for frailty using gait speed and handgrip strength, screen for previously undiagnosed comorbid conditions, and offer frail older adults multi-faceted interventions that identify and address unrecognized medical and psychosocial needs. To date, we have assessed 965 older adults through this program; 14% were identified as frail based on gait speed alone, and 5% identified as frail based on gait speed with grip strength. The C5-75 program aims to re-conceptualize care from reactive interventions post-diagnosis for single disease states to a more proactive approach aimed at identifying older adults who are at highest risk of poor health outcomes, case-finding for unrecognized co-existing conditions, and targeting interventions to maintain health and well-being and potentially reduce vulnerability and health destabilization.

Spirometry in Greenland: a cross-sectional study on patients treated with medication targeting obstructive pulmonary disease

BACKGROUND

Chronic obstructive pulmonary disease (COPD) is globally increasing in frequency and is expected to be the third largest cause of death by 2020. Smoking is the main risk factor of developing COPD. In Greenland, more than half of the adult population are daily smokers, and COPD may be common. International guidelines recommend the usage of spirometry as a golden standard for diagnosing COPD. The current number of spirometries performed among patients treated with medication targeting obstructive pulmonary disease in Greenland remains unexplored.

OBJECTIVE

To estimate the prevalence of patients aged 50 years or above treated with medication targeting obstructive pulmonary disease and the extent to which spirometry was performed among them within 2 years.

DESIGN

An observational, cross-sectional study based on the review of data obtained from electronic medical records in Greenland was performed. The inclusion criterion was that patients must have been permanent residents aged 50 years or above who had medication targeting obstructive pulmonary disease prescribed within a period of 15 months prior to data extraction. A full review of electronic patient records was done on each of the identified users of medication targeting obstructive pulmonary disease. Information on age, gender, town and spirometry was registered for each patient within the period from October 2013 to October 2015.

RESULTS

The prevalence of patients treated with medication targeting obstructive pulmonary disease aged 50 years or above was 7.9%. Of those, 34.8% had spirometry performed within 2 years and 50% had a forced expiratory volume (1 sec)/ forced vital capacity (FEV1/FVC) under 70% indicating obstructive pulmonary disease.

CONCLUSION

The use of medication targeting obstructive pulmonary disease among patients over 50 years old is common in Greenland. About one third of the patients had a spirometry performed within 2 years. To further increase spirometry performance, it is recommended to explore possible barriers in health care professionals' usage of spirometry in different health care settings in Greenland.
