Chronic kidney disease (CKD) is defined as abnormalities in kidney structure or function that last longer than three months, with significant health consequences (1). CKD is a major public health issue whose global prevalence is predicted to be 13.4% (2). A study by Süleymanlar et al. shows that the prevalence of CKD in Turkey is around 15.7% (3). According to the 2020 Turkish Society of Nephrology (TSN) (4), the total number of patients receiving chronic hemodialysis (HD) in Turkey were 60,558, and patients with kidney transplantation (KTx) are 19,405.
Based on the 2020 TSN report, the COVID-19 pandemic resulted in remarkable changes in treatment offered to patients with CKD in Turkey. Many kidney transplant centres were forced to halt their operations, resulting in a considerable drop in the number of kidney transplants as well as a disruption in the follow-up of patients with transplants as compared to prior years (4). It is well established that individuals with chronic conditions are more vulnerable to the COVID-19 virus (5). In accordance with the data of the same report, the incidence of COVID-19 was 19.6% in patients receiving HD and 8.7% in patients with KTx, while the mortality rate due to COVID-19 was 24.4% in patients receiving HD and 11.3% in patients with KTx (4). Other studies demonstrated that individuals with CKD were more susceptible to COVID-19 and had a higher risk of death from the virus than healthy individuals (6).
A high level of patient engagement and interest is a requirement for long-term CKD treatment management, both in decision-making and in the implementation of care (7). Treatment adherence is important in patients with CKD, due to the use of excessive medications and the need for frequent hospital visits during the treatment process (8). Many comorbidities including hypertension and diabetes are common in patients with CKD, and people on average are reported to use around 8–10 tablets of medication per day (9). During COVID-19 social distancing, health service disruptions, and lockdowns were reported to impact the treatment, management, and lack of follow-up could result in patient adversity (6, 10, 11). Thus, self-management of patients with CKD gained importance during COVID-19.
Self-management behaviour in patients with chronic diseases is defined as patients’ dedicated commitment towards a healthcare activity to maintain a satisfying quality of life by solving problems, controlling the chronic disease, and adjusting their daily life to monitor their own condition and emotions (12). Self-management in patients with CKD may include spotting initial warnings, self-adjustments of home-care regimes, and adhering to medication, exercise, and diet recommendations (7). Since CKD is irreversible and patients with HD and KTx need lifelong therapy and their self-management behaviours play a critical role in determining their life quality and quantity (12). However, how people value and make changes to adopt these self-management practices is crucial for the success of such management plans.
The HBM was the mostly used model to understand how patients with CKD view health threats, adherence, and self-management behaviour (13–17). The HBM states that an individual’s adoption of appropriate behaviour to prevent a health problem may be influenced by certain individual factors such as perceived susceptibility (beliefs about the possibility of getting a disease or condition), perceived severity (subjective assessment of the severity of a health problem and its possible consequences), perceived benefits (perceived benefits of an action to decrease the risk of disease), perceived barriers (belief about the obstacles of taking action), cues to action (perceived motivators towards taking action), and self-efficacy (an individual's confidence of his or her competence to successfully perform a behaviour (Champion and Skinner, 2008).
The aim of this study was to explore factors that might have an impact on the adoption of self-management behaviour of patients with CKD during COVID-19 by using the HBM in Turkey.
