Discuss About The Proficiencies Improve Health Care Quality.
This research study focuses on the chronic obstructive pulmonary disease (COPD) that affects at-least one in three patients in United Kingdom, necessitating re-hospitalizations within 28 days of previous hospitalization for exacerbations. GOLD (2013) has stated that 33 per 1,000 people are affected with COPD in UK with 26.2% of them experience at-least one exacerbations in a year and 25.5% experience more than one exacerbations. According to Linton (2015), appropriate self management techniques can be used to reduce such re-hospitalizations in COPD patients (Brown, 2017). As, patients are the one who typically notices the early changes in their conditions, it is highly important for them to clearly understand what does COPD exacerbations mean, how to find-out the deteriorating features and how to react for it (Hinkle, 2014). Therefore, the current study by Williams (2014) scrutinizes the extent to which the patients with COPD understands, identifies and also manages the COPD exacerbations.
In-regard to this issue, the previous researches indicate that there is no clear consensus as how to define COPD exacerbations along with poor understanding of how it is identified and understood by patients with COPD. Certain studies suggest that the COPD patients have difficulty with medical terminologies and has no clear understanding of the meaning of COPD exacerbations while other studies assures that the patients with COPD have knowledge about imminent exacerbations. In 2013, Harrison has conducted a meta-analysis which shows that the previous qualitative researches have analyzed only about the experience of exacerbation by the COPD patients rather than their understanding and identification of exacerbation features. Yet COPD patients feel safe with the self management of exacerbations at home setting. According to Sundh (2013), though several studies have been published to describe about the assessment of COPD exacerbation, no one has clearly explained about the recognition and management of COPD exacerbations by the patients (Risor, 2013).
Research into this area is highly significant because an effective self- management of COPD which includes early recognition and prompt management of COPD exacerbations by patients themselves; can minimize number of hospital re-admissions and enhance patient outcomes.
According to PoIit (2016), the accomplishments that are specifically framed to achieve what the researchers have intended to inquire is termed as study aims or objectives. The researchers of this study have given a clear, acceptable and achievable aim that are related to their study problem as ‘to explore the COPD patient’s understanding with experience in recognizing as well as managing exacerbations of COPD at home’, as suggested by Boswell (2017).
Williams (2014) has selected a qualitative research design that involves investigating the phenomenon basically in an in-depth and holistic manner by collecting a rich narrative source (Polit, 2016).
The main characteristics of qualitative research design identified are as follows: It is highly flexible as well as elastic with capability to adjust to the phenomenon being learned during data collection period. It involves a merge of several data collecting strategies and has tendency to understand the whole (holistic striving) (Grove, 2015). It also necessitates intense involvement by the researchers for a longer period of time requiring continuous analysis of the collected data so as to create subsequent strategies (Melnyk, 2014). Moreover, qualitative researches are conducted to evaluate and enhance the understanding of individual’s experiences of difficulties, discomforts, etc.
Polit (2016) has suggested that qualitative studies give sound knowledge than quantitative studies in evaluating the individual’s emotions and in exploring the individual as a whole. Qualitative research is an interactive and subjective approach that can be used to explore the etiologies, experiences and facts about things (Yin, 2015). Hence, this qualitative design can definitely aid the researchers to attain their objective as ‘to explore the COPD patient’s experience in recognizing as well as managing the exacerbations of COPD at home’ and find solutions.
In this study, the patient’s characteristics that are used to collect data are as follows: age (years), sex (male/ female), COPD’s severity (GOLD stage- II, III and IV), time- duration of symptoms of COPD (years), usage of oxygen at home, previous history of attendance to any pulmonary rehabilitation centers and living set up of patients as living with spouse or family members or living alone.
Eligibility criteria are the criteria designating the particular attributes of the population (target) by which subjects are included for participating in the study (Gerrish, 2015). In this research study, the inclusion criteria specifying the characteristics that the population should possess while the exclusion criteria indicating the characteristics that the subjects should never possess, was followed appropriately, as given by Polit (2016). Williams (2014) has selected their target population of patients diagnosed with chronic obstructive pulmonary disease based on the inclusion and exclusion criteria. They identified and recruited those COPD patients who met their eligibility criteria for the study from the admission records of hospitals, patients attending pulmonary rehabilitation programmes and those who got general practice service from the respiratory- research nurses. Their eligibility criteria include: Patients with COPD; age- above 40 years; a forced expiratory lung- volume in 1 s (FEV1), post broncho-dilator <80% with predicted ratio of FEV1 to forced vital pulmonary capacity (FVC) of <0.70, smoking history for over 10 pack years, MRC’s dyspnea scale showing more than 2, got registered in a general health care practice. Patients at increased risk for exacerbation requiring home management or any hospitalized admissions in the past, got referred for any lung rehabilitation programmes, no history of other significant pulmonary disorders, no history of chronic (right/ left sided) heart failure as given under the classification system of New York’s Heart Association classification system with severe Grade (IV), able to sign in an informed consent with life expectancy of more than 3 months period and able to clearly understand spoken and written English, as supported by Jones (2014).
According to Yin (2015), eligibility criteria have to be identified before commencement of the subject recruitment. This is because appropriate selection of inclusion as well as exclusion criteria will promote the external and internal validity of the findings of study, enhance feasibility of study, control the project’s cost and minimize ethical constraints (Grove, 2015). Additionally, construct validity of any study is improved only when a good match is maintained between the eligibility criteria and population construct (Polit, 2016). Such recruitments can improve the selected population’s homogeneity by controlling confounding (extraneous) variables and also increases the chance of obtaining unbiased study interpretation (McDonagh, 2013). The inclusion and exclusion criteria mostly reflect certain considerations other than substantive/ theoretical aspects.
They have selected purposive (purposeful) sampling approach which is type of non- probability method that involves recruiting study participants in a subjective manner but prevents external & objective method of assessing the typical-ness of recruited samples (Grove, 2015).
In this approach, the researchers will decide purposely to recruit samples that are judged to be the typical of population and/or specifically knowledgeable about the study issues (Polit, 2016). This method could infer subjectivity in the selection of subjects by minimizing the likelihood of participants to be selected, yet this method is a best sampling method in qualitative researches which necessitates volunteer informants. Hence, these purposive samples will help the researchers to explore the experiences of COPD patients in recognizing as well as treating exacerbations at home based on their objectives.
Data collection involves meticulous collection of data to solve the study’s problem (LoBiondo-Wood, 2014). The researchers have utilized semi- structured interview method in which both the interviewer and subjects have engaged in a formal interview (Williams, 2014). The researchers have developed a semi- structured interview guide with topics and questions needed for conversation and to gather narrative data from COPD patients at home. They have followed their guide while asking questions on selective topics such as how COPD patients experienced, identified as well as self- management exacerbations and has encouraged the subjects to respond within the selected topics, as suggested by Polit (2016). Six of the subjects had their spouse/ family member with them at the time of interview. They have collected narrative or non- numeric qualitative data from the subjects in the form of transcripts (Grove, 2015).
The researchers have audio- recorded their field notes soon after their interview to enhance the context of the interview and also helps in data analysis process (Williams, 2014). Then were transcribed and analyzed by utilizing grounded theory approach.
Their data collecting method exactly fits their aim of exploring the patient’s experience in recognizing as well as treating COPD exacerbations at home. This is evident in their topic guide with interview questions focusing specifically about the experience, identification and management of exacerbations of COPD, based on their study’s aim, as suggested by Grove (2015).
There are certain advantages of using semi- structured interviews such as: empowering interviewers to prepare themselves ahead to be competent in interview; gives freedom to the participants to express their views in their own terms; enables reliable and comparable narrative data; enables two way communication by permitting the participants to question the researcher (acts as an extension tool); gives answers with its reasons for it and also allows the participants to describe sensitive issues (Yin, 2016). Its disadvantages include: the need for interviewing skill; require sufficient number of subjects to draw general comparisons; necessitates careful preparation to avoid posing prescriptive and leading questions; skills to analyze collected data (risk of construing too much); consumes time; researcher should ensure confidentiality and resource intensive (Gerrish, 2015).
The researchers could have chosen the alternate method of focused group interview method in their study. In this method, the researchers will gather a group of 4 to more subjects for a discussion with a prepared set of question (Polit, 2016). They conduct planned discussion sessions to collect rich data from the subjects. This will motivate the subjects (homogeneous group) to ventilate their own views in a common background.
How was the data analyzed? (Reference required)
Qualitative analysis is the process of organization as well as interpretation of the qualitative (narrative) data with the purpose of scrutinizing underlying categories or pattern of relationships (Grove, 2015). Williams et al (2015) has done qualitizing by reading as well as interpreting the quantitative data in a narrative fashion. As semi- structured interview method contains open ended questions with possibility of diversions in discussion, the interviews should be audio taped and then transcribed into analysis (Grove, 2015). This is evident in this study in which the researchers have tape recorded the collected information, transcribed the verbatim and have imported their transcripts into NVIVO-10 (qualitative software data programme) in-order to store, organize and analyze the data. They carried out analysis by grounded theory method along with comparative (constant) method, open coding, axial coding and selective coding with memo-writing to explore the theoretical linkages and conceptual data from the informations collected.
According to Yin (2016), it is highly important to select applicable methods of data analysis in qualitative research as it involves organization of narrative data, structuring collected data, elicit meaning from collected information to develop themes, theories and frameworks. Moreover, qualitative analysis is time consuming and labor intensifying process that requires high-creativity, increased effort with concept sensitivity. Additionally, the challenges in qualitative analysis include: lack of universal analytical rules, increased amount of work required for analysis and reducing qualitative data for reporting by balancing conciseness and richness. Hence, appropriate methods should be selected for an qualitative analysis (Polit, 2016).
Williams (2014) has given that they ensured the rigour in the analytical process (i.e. coding process) throughout their study among research team members. Additionally, they have double coded 10% of transcripts by one of the co-authors having good experience in qualitative analysis, who was not a study team member and this didn’t produced any conflicting results. Moreover, the text suggests that the entire research team had met each other at regular intervals in-order to discuss their data analysis as well as data interpretation process. The above processes have aided them to maintain transparency and enhance credibility in their findings (Polit, 2016).
The findings of this study indicate that the COPD patients were able to identify COPD exacerbations at home based on the visible and invisible symptoms. Visible or measurable (objective) symptoms include physical symptoms (severe cough, sputum production & temperature) and physical limitations while invisible (subjective) symptoms include chest sensations (soreness and tightness of chest, heavy chest, and breathlessness) and bodily knowledge (lack of energy and knowing). Williams (2014) emphasized that most of the patients have identified their exacerbations by using both these approaches, based on the symptoms that induced more impact on the patient’s well-being. They also noted that patients have used some self managing strategies at the exacerbation time that includes taking self medications as antibiotics and oral steroids as well as monitoring their recovery. They have contacted the health care personnels whenever the COPD patients felt that they will not be able to manage themselves. All these findings indicate that COPD patients have used objective bio-markers assessment along with medical knowledge and their invisible symptoms that they have experienced, in identifying and managing COPD exacerbations. They concluded that the health care personnels and physicians should consider the patient’s knowledge and should integrate this in the patient’s care plans so as to enable early identification and prompt treatment of COPD exacerbations.
The study findings can be transferred into settings with newly diagnosed COPD patients as it can impose certain value in educating them about early recognition of acute COPD exacerbations from subjective and objective symptoms as well as appropriate treatment of these symptoms with self managing strategies (self medications and monitoring their recovery). Their study findings can therefore be utilized to propose further researches to quantify these exacerbation experiences and clarify the existing definitions for COPD exacerbations (Williams, 2014). Studies should also be conducted to pose clinical measures for early recognition and prompt management of exacerbation, especially based on the tele-monitoring services.
