To live a life with COPD - the consequences of symptom burden

Geriatric drug delivery - barriers, current technologies and the road ahead

The geriatric population encompasses the largest part of the health care system worldwide. Chronic medical conditions are highly prevalent in the elderly, consequently, due to their complex health needs, there is a significant rate of multi-drug therapy. Despite the high numbers of medications prescribed, geriatric patients face several barriers when it comes to successful drug delivery including alterations in cognitive and physical function. The current review highlights the impact of chronic diseases on the ageing population along with how changes in drug pharmacokinetics could impact drug efficacy and safety. Also discussed are applications of administration routes in the geriatric population and complications that could arise. A focus is placed on the traditional and upcoming drug delivery advancements being employed in seniors with a focus addressing obstacles faced by this patient category. Nanomedicines, three-dimensional printing, long-acting formulations, transdermal systems, orally disintegrating tablets, and shape/taste modification technologies are discussed. Several barriers to drug delivery in the elderly have been identified in literature and directions for future studies should focus on addressing these gaps for geriatric drug formulation development including personalised medicine, insights into novel drug delivery systems like nanomedicines, methods for decreasing pill burden and shape/size modifications.ARTICLE HIGHLIGHTSTypically, senior citizens take more medications than any other patient population, yet most drug delivery technologies are not tailored to address the specific cognitive and physical barriers that these individuals encounter.The safety of drug delivery systems in the elderly patients should be prioritised with considerations on changes in pharmacokinetics with age, use of non-toxic excipients, and selecting drugs with minimal off-target side effects.Several commercialised and upcoming drug delivery technologies have begun to address the current limitations that the ageing population faces.Future research should focus on applying novel strategies like 3D printing, personalised medicine, and long-acting formulations to improve drug delivery to elderly patients.

Chronic obstructive pulmonary diseasés impact on the affected person and next of kin: A mixed methods study

OBJECTIVES

Severe chronic obstructive pulmonary disease affects and changes the lives of both affected persons and next of kin. There is a need for support and a sense of coherence to manage the life situation and minimize the symptom and caregiver burden. The aim of this study was to diverge or converge views of symptom burden, caregiver burden, the need for support, and sense of coherence in persons with chronic obstructive pulmonary disease and their next of kin to gain a deeper and broader knowledge and understanding.

METHODS

A mixed methods study with data from interviews and four validated questionnaires from persons affected by chronic obstructive pulmonary disease in GOLD stages III and IV and their next of kin.

RESULTS

Questionnaires from 112 persons affected by chronic obstructive pulmonary disease, and 71 next of kin, together with 25 and 21 interviews, show that; there is a difference between estimated symptoms and caregiver burden and experiences expressed in their own words. There is also a defect regarding meaningfulness, comprehensibility, and manageability affecting daily life. Symptoms and caregiver burden, together with the sense of coherence, strengthen the need for support.

DISCUSSION

The complexity of the life situation leads to a need for supportive interventions to strengthen internal and external resources.

Living with COPD: understanding patient experiences through the lens of photovoice

BACKGROUND

Conventional quantitative or qualitative methodologies may not encompass the wide array of experiences of individuals living with Chronic Obstructive Pulmonary Disease (COPD). We used a novel approach - photovoice-to understand the impact of COPD on activities of daily living (ADLs) in a multicultural Asian country.

METHODS

We recruited a purposive sample of eight patients from the outpatient clinics of the National University Health System, Singapore, between December 2020 and August 2021. We adopted a photovoice approach for data collection; participants were invited to take photos of how ADLs were impacted by COPD and attend a follow-up interview. An Interpretative Phenomenological Analysis method was used to analyze the data. Data saturation was reached by the seventh patient.

RESULTS

COPD and the resulting breathlessness had a profound and diverse impact on our participants' lives. Living with COPD required substantial changes to how everyday tasks are performed, and participants learnt new strategies to deal with such tasks. A mixture of active and passive coping styles was evident. Feelings of frustration, anxiety and a sense of isolation were also reported. Contextual factors impacting ADLs included challenging climatic conditions and the local popularity of traditional or alternative medicine.

CONCLUSION

The photovoice technique improved our understanding of the lived experiences of COPD patients and can benefit those who struggle to articulate their views by offering a different way to communicate beyond conventional interviewing.

Calidad de vida del paciente con enfermedad pulmonar obstructiva crónica

Introducción: los pacientes que padecen de patologías crónicas, como la enfermedad pulmonar obstructiva, experimentan diversos cambios en su estado de salud, que los lleva a modificar su percepción de bienestar. Por ello, la evaluación de la calidad de vida se hace necesaria. Objetivo: describir, de forma global y por dimensiones, la calidad de vida de sujetos que padecen de Enfermedad Pulmonar Obstructiva Crónica (EPOC), que acudieron a la consulta externa de una institución hospitalaria en el primer semestre de 2018 en Bogotá. Método: las características sociodemográficas y la calidad de vida relacionada con salud se midieron en un estudio descriptivo transversal. La muestra estuvo conformada por 80 pacientes. El análisis se fundamentó en la aplicación de frecuencias y porcentajes para las variables sociodemográficas, y de medidas de tendencia central para la variable principal de la investigación. Resultados: los pacientes con EPOC reportaron una edad media de 73 años, fueron predominantemente mujeres, casadas, con bajo nivel de escolaridad y con una media en la calidad de vida de 36,67. La subescala más afectada fue la de actividad y la menos comprometida fue la dimensión de impacto. Conclusiones: la calidad de vida relacionada con la salud es un indicador de las consecuencias que tiene la EPOC sobre la ejecución de las diferentes actividades físicas y sociales de los pacientes, por ello, su evaluación se convierte en un aspecto fundamental en la valoración e intervención de dicha población.

Symptom burden and functional performance in patients with chronic obstructive pulmonary disease

BACKGROUND

The burden of COPD is growing, and it is one of the leading disease burdens worldwide. Studies on symptom burden as a multidimensional concept in COPD and functional performance are lacking, and little is known about the effect of multiple symptoms and symptom burden on functional performance.

METHODS

A descriptive, cross-sectional correlational survey design was used. The Memorial Symptom Assessment Scale (MSAS) and the Functional Performance Inventory-Short Form (FPI-SF) were used to measure the symptom burden and functional performance. Data were analyzed using descriptive and inferential statistics. Participants (n = 214) were recruited from the respiratory outpatient clinic in one of the teaching hospitals in Ireland.

RESULTS

Patients with COPD, regardless of classification, experienced significant physical and psychological symptom burden. A total of 20 symptoms were negatively correlated with overall functional performance, indicating a high symptom burden for those symptoms was associated with low overall functional performance. A statistically significant negative correlation between physical symptom burden, psychological symptom burden, total symptom burden, and functional performance was found.

CONCLUSION

Patients with COPD experience a significant symptom burden and low functional performance. Decreased functional performance was not related only to a single burdensome symptom, but may also be related to the contribution of several physical/psychological burdensome symptoms, or both. Assessment and management of these symptoms are essential and imply that alleviating these symptoms' burden may promote improved functional performance. This study supported the growing body of evidence of the need for patients with advanced COPD to receive palliative care.

Informal carers in Sweden - striving for partnership

Purpose

Informal carers have an important role in society through their care and support of their long-term ill relatives. Providing informal care is challenging and can lead to caregiver burden; moreover, many support needs of the carers are not met, leading to confusion, disappointment and frustration. We conducted an interview study to clarify the meaning of support given and received by informal carers to relatives with chronic obstructive pulmonary disease or chronic heart failure.

Methods

We purposively selected and recruited informants via participants in another study, thereby conducting interviews over the phone from June 2016 to May 2017. In total, we conducted 14 interviews with 12 informants. All interviews were transcribed verbatim and the content was analysed using a phenomenological hermeneutical approach.

Result and conclusion

Our comprehensive understanding of the meaning of support for these carers is twofold: it is a self-evident struggle for the good life of their relatives and that they want to be carers in partnership. The healthcare system must recognize the efforts of carers and include them in the strategic planning and operational stages of care and treatment for people with long-term illness.

Experiences of Pulmonary Rehabilitation in People Living with Chronic Obstructive Pulmonary Disease and Frailty. A Qualitative Interview Study

Rationale: People living with both chronic obstructive pulmonary disease (COPD) and frailty have high potential to benefit from pulmonary rehabilitation but face challenges completing programs. However, research to understand ways to optimize participation in this group is lacking.

Objectives: To explore the experiences, needs, and preferences of people with COPD and frailty referred for outpatient pulmonary rehabilitation.

Methods: Semistructured interviews with people with COPD and physical frailty, purposively sampled by age, living status, level of frailty, and completion of pulmonary rehabilitation. Thematic analysis with a critical realist perspective was used, involving relevant stakeholders with clinical, academic, and lived experience for interpretive rigor.

Results: Nineteen people with COPD and frailty were interviewed, with a median age of 78 years (range, 58–88). Nine did not complete their pulmonary rehabilitation program. Four themes were identified: striving to adapt to multidimensional loss, tensions of balancing support with independence, pulmonary rehabilitation as a challenge worth facing, and overcoming unpredictable disruptions to participation. Participants described constantly adapting to their changing health and resulting multidimensional losses (e.g., functional abilities, relationships, confidence). This involved traversing between independence and seeking support, set against a mismatch between their needs and what support is available. People with COPD and frailty can be highly motivated to participate in pulmonary rehabilitation, despite the physical and mental demands it entails, and report a range of benefits. Yet in the context of changeable health, they must often overcome multiple unpredictable disruptions to completing rehabilitation programs. Participant determination and flexibility of services can facilitate ongoing attendance, but for some, these unpredictable disruptions erode their motivation to attend.

Conclusions: People with COPD and frailty experience accumulating, multidimensional loss. This group are motivated to complete pulmonary rehabilitation but often require additional support and flexibility owing to fluctuating and unpredictable health. Person-centered approaches should be considered to minimize disruptive health events and support pulmonary rehabilitation participation and completion. Service adaptations could allow more flexibility to meet the changing needs of this group and enable communication around how pulmonary rehabilitation might align with their priorities.

Living with an ever-present breathlessness: Women's experiences of living with chronic obstructive pulmonary disease stage III or IV

BACKGROUND

Living with chronic obstructive pulmonary disease stage III or IV has a major impact on a person's everyday life. This qualitative study focuses on women with chronic obstructive pulmonary disease stage III or IV.

AIM

The aim of this study was to describe women's experiences of living with chronic obstructive pulmonary disease stage III or IV.

METHOD

A purposive sample of fifteen women with chronic obstructive pulmonary disease stage III or IV participated in the study. Data were collected through individual semi-structured interviews that were subjected to qualitative content analysis.

FINDINGS

One theme was identified, stabilizing an ever-present breathlessness by restoring strength, and three categories are as follows: managing a restricted everyday life as an expert of their illness, being afraid of contracting infections leading to suffocation and suffering and importance of continuous help and support from significant others and digital media. Breathlessness restricted women with chronic obstructive pulmonary disease, living with a body they have to wait for. Managing everyday life was adapted to their limited abilities and energy. This required detailed planning, good knowledge of their breathing and body. Women were afraid of contracting life-threatening infections that caused suffering, especially COVID-19. The fear leads to isolation and digital media was described as an important means of communication. Significant others gave support and help that was practical and emotional. Women with chronic obstructive pulmonary disease experienced lack of continuous help and support from healthcare professionals.

CONCLUSION

Stabilizing an ever-present breathlessness by restoring strength required women with chronic obstructive pulmonary disease stage III or IV to conduct detailed planning to manage everyday life. Being afraid of contracting infections and the consequences of suffocation had increased since the pandemic COVID-19 outbreak, which led to self-isolation and an inactive everyday life. To get help, support and socialize, women used digital media.

The Effects of Low Pressure Domiciliary Non-Invasive Ventilation on Clinical Outcomes in Patients with Severe COPD Regardless Having Hypercapnia

Background

The effectiveness of non-invasive home ventilation in patients with severe chronic obstructive pulmonary disease (COPD) is lacking. Non-invasive home ventilation might be more effective when high ventilator settings are used. However, high ventilator settings might reduce patient adherence. We have developed a multidisciplinary approach (ventilation practitioners, 24 hours support of respiratory nurses, physicians) to non-invasive ventilation aimed at optimizing patient adherence using low ventilator settings in severe COPD patients with high disease burden irrespectively having hypercapnia.

Methods

We included in a proof of concept, prospective interventional study, 48 GOLD stage III-IV COPD patients with a high disease burden (≥2 exacerbations in a year, and Medical Research Council dyspnea scores ≥3). Outcome measures included hospital admissions, capillary pCO_2, Medical Research Council dyspnea scores (MRC), Clinical COPD Questionnaire scores (CCQ) and Hospital Anxiety and Depression Scale (HADS).

Results

After 1 year 32 patients could be evaluated. Hospital admissions decreased by 1.0 admission (mean difference ± SD: 1.0 ± 1.48; p = 0.001). In-hospital days decreased by 10.0 days (10.0 ± 15.48; p = 0.001). Capillary pCO₂ decreased by 0.33 kPa (0.33 ± 0.81: p = 0.03). The MRC dyspnea score decreased by 0.66 (0.66 ± 1.35; p = 0.02). The CCQ score decreased by 0.59 (0.59 ± 1.39; p = 0.03). The HADS anxiety score decreased by 1.64 (1.64 ± 3.12; p = 0.01). The HADS depression score decreased by 1.64 (1.64 ± 3.91; p = 0.04).

Conclusion

A proof of concept multidisciplinary approach, using low pressure domiciliary non-invasive ventilation, aimed at optimizing patient adherence in severe COPD patients regardless having hypercapnia, reduced hospital admissions and improved symptoms and quality of life measures. This may imply that severe COPD patients with high disease burden, irrespective being hypercapnic, are candidates to be treated with low pressure domiciliary non-invasive ventilation.

The information needs of people with COPD-The holistic approach with special reference to gender and time since diagnosis

Aims

The aim of this study was to determine what kinds of unmet information needs people with COPD have and whether there are differences in information needs between genders or based on the time since COPD diagnosis.

Design

A descriptive cross‐sectional study.

Methods

Data on people with COPD (N = 169) were collected from a two‐part questionnaire distributed via website. On the first part, information needs concerning the medical aspects of self‐management were measured by the Lung Information Needs Questionnaire (LINQ). On the second part, which was developed specifically for this study, a more holistic view of self‐management counselling was sought. Statistical methods were used to analyse the data.

Results

The respondents had wide‐ranging information needs in many areas of COPD self‐management. The most often reported areas of unmet information needs included exacerbations, diet, fatigue, stress and anxiety, palliative care and sexual life. The information needs varied by gender and time since COPD diagnosis.

Heavy shackles: The experience of symptom distress and coping behaviors of Chinese patients with chronic obstructive pulmonary disease

People with chronic obstructive pulmonary disease exhibit various symptoms, some of which can negatively affect their daily lives. Thus, they may adopt coping behaviors to improve their condition. This qualitative descriptive study investigated symptom distress and coping behaviors among 19 Chinese patients with chronic obstructive pulmonary disease using individual, semi-structured, face-to-face interviews. We identified the following three themes for the patients' symptom distress: distressing symptoms, inescapable imprisonment, and no choice other than being a burden to the family. The various coping behaviors of the patients were categorized into the following three themes: struggle during the medical treatment process, careful maintenance of daily life, and coping with negative emotions. Although all patients experienced physical and psychological distress, they displayed a strong desire to improve their lives and health. By recognizing the patients' symptom distress and coping behaviors, tailored interventions could be developed to improve the quality of their lives.
