Literature Review on the COVID-19 Pandemic

The viral disease COVID-19, due to the SARS-CoV-2 virus, gives rise to a severe outbreak that affects people globally. The immediate impacts of the virus have been researched, and there is concern about the further consequences on people's health. It is essential to comprehend these effects as many people remain symptomatic even after the viremia phase is over (Adorjan & Stubbe, 2023). Studies suggest that many people who contracted the virus continue to experience symptoms like fatigue, respiratory problems, and mental disorders even after recovery. This literature review will seek to pinpoint COVID-19 patients' long-term symptoms, how such effects impact their quality of life, and why they require ongoing care.

Research Question

“What are the long-term health impacts of the COVID-19 pandemic on survivors?"

Article Search Strategy

A specific search strategy was used to explore the health consequences of COVID-19 on patients' future health, including typical databases like PubMed and Google Scholar. The articles were searched depending on the year of publication, and only those published within the last five years were wasted in the analysis. Manipulation and outcome of the search involved the use of Boolean operators. The specific search terms included “COVID-19”, “long-term consequences," “survivors," “health outcomes," and “long COVID." The filters used in the search were restricted to peer-reviewed studies and observational cohorts only to reduce bias. Therefore, this article search approach created grounds to evaluate the long-term impact of COVID-19 on its survivors. Ultimately, by applying the above search strategy, seven articles met the search criteria, including Adorjan & Stubbe (2023), Jain et al. (2023), Lopez-Leon et al. (2021), Ma et al. (2022), McPeake et al. (2021); O' Mahony et al. (2021) and Todt et al. (2021).

Literature Review

The literature by Adorjan & Stubbe (2023) highlighted that COVID-19's health effects on survivors in the long term are diverse and extend beyond the psychological and physical aspects. According to the authors, it is evidenced that a large number of COVID-19 patients have long-term symptoms like weakness, sleep disturbances, anxiety, depression, and post-traumatic disorder post-traumatic stress disorder (PTSD) at least one year after the infection. Preconditions for these psychosocial consequences include smoking, alcohol consumption, low education level, and the presence of chronic diseases. The authors’ findings have also shown that symptoms of depression and loneliness have been rising in the recent past. Consequently, life satisfaction has lowered across all ages, more so for vulnerable individuals and the population, especially young people and those with prior mental health disorders. Additionally, the pandemic has worsened other problems like sleeplessness and stress on carers or other family members attending to the survivors, resulting in significant changes in the psychological, economic, and physical realms of survival. Thus, these outcomes call for introducing practical and directed psychological treatment and care for survivors and their families after the disaster.

A study by Jain et al. (2023) evaluates prolonged health consequences among patients who contracted severe COVID-19 and had been treated in the ICU. They used quality of life (QoL) and workability questionnaires and reported substantial reductions among these survivors. The study involved 491 participants, and it was revealed that new psychological disorders and sleep disruptions were typical, and a significant number of patients commenced sleep medications after being discharged. Prolonged mechanical ventilation and ICU stay have been identified as independent predictors of poor QoL and reduced work ability. The study also revealed that COVID-19 patients who had severe symptoms reported poor sleep quality and higher symptoms of anxiety and depression than patients in the non-severe group, especially elderly patients and patients who had to be hospitalized for an extended period. The result once again confirms the need for constant medical and psychological assistance to such patients to cope with the complications that arise after severe COVID-19.

Lopez-Leon et al. (2021) explore how COVID-19 affects survivors and their families in various aspects of their lives. It acknowledges that 80% of patients have at least one post-acute symptom, which lasts for several months after the acute phase of the infection. Some of the longest-lasting symptoms include fatigue 58%, headache 44%, attention disorder 27%, hair loss 25% and dyspnea 24%. The study also notes that such symptoms can last for weeks to months and occur regardless of the initial severity of the infection, especially in people who were not hospitalized. The article emphasizes that coordinated care and prevention of these lasting outcomes are best achieved through an interdisciplinary effort with individual medical treatments and holistic rehabilitation plans. Moreover, this study suggests that more research is needed to divide results by sex, age, comorbidities, and the severity of the first COVID-19 infection to mitigate the virus's long-term effects on human health.

In their article, Ma et al. (2022) highlight the various long-term effects that COVID-19 patients experience even after recovery. This total consists of data from 40 observational cohort studies that involve 10,945 cases of SARS-CoV-2 infection. The review indicates that long-term outcomes were reported by 63.87% of the patients at six months, slightly lower at 12 months, at 58.89%. Signs and symptoms may present as general weakness or tiredness, slight breathlessness, changes in CT scans, and lung function tests. Patient concerns included psychological problems like anxiety and depression, pain or discomfort, which all had a negative impact on the quality of life. These findings show that the effects of COVID-19 on the population's health are long-term and require continued medical attention, physical therapy, and psychological counseling, in addition to the continuation of public health measures to deal with the consequences of the virus.

The article by McPeake et al. (2021) covers the effects of COVID-19 on the health of the survivors, emphasizing the psychological and physical effects of the disease on the families of patients in critical condition. A multicentered survey conducted in Scotland found that survivors' relatives suffered from anxiety, depression, and sleep disorders. The participants endorsed the Carer Strain Index, which revealed that 44. 7% of the family members indicated that they had experienced significant stress, and most of the changes were in terms of financial and emotional demands. Concerning the effects of employment, it was found that 34% of family members require employment changes upon discharge. The study also emphasizes the importance of developing support interventions for patients and their families because several aspects of the burden are worsened by reduced hospital access and social isolation during the pandemic.

The study by O'Mahony et al. (2022) aimed to elaborate on the health effects of COVID-19 on the survivors using the Irish sample. It reveals the fact that a large number of individuals who recovered from COVID-19 are not symptom-free and suffer from post-acute sequelae of COVID-19 (PASC) with impact on multiple organ systems. In the presented study, 89% of the participants reported that they had not managed to reach the pre-COVID health status, with the median of having 8 symptoms lasting up to 12 months. Some of the manifestations that patients experience are constant fatigue, palpitations, chest pain, difficulties with memory, and muscle aches. The study also showed that those symptoms affect daily activities, workability, and quality of life with moderate to severe limitations, as expressed by the respondents. Mental health also had effects in this study; 33% reported moderate anxiety or moderate depression. The results imply that it is necessary to utilize variable and integral strategies to address the various and long-lasting manifestations of COVID-19.

An article by Todt et al. (2021) explores the implications of COVID-19 on the patient's health at the three-month follow-up after being discharged from the hospital. The study sample comprised 251 participants, and the findings indicated several long-term health complications. Participants reported a 27. 9% rise in breathlessness and 32.2% anxiety or depression. Self-identified HRQoL was significantly reduced in all domains, especially in pain/discomfort and anxiety/depression. These factors made outcomes worse and included the female sex and the requirement of intensive care during hospitalization. Furthermore, 20.3% of participants were required to go to the emergency department, and 6. 8% were hospitalized after the initial discharge. These findings reaffirm the need for long-term medical care and psychological counseling for COVID-19 patients and survivors, further stressing the severity and duration of the pandemic's effects on human lives and the healthcare industry.

Conclusion

COVID-19 has short-term and long-term impacts on the survivors in terms of the physical and mental well-being of patients. Some of the symptoms include fatigue, respiratory problems, and cognitive disorders, and many of them have a poor quality of life. Long-term symptoms like anxiety, depression, sleep problems, and PTSD are described by the survivors even a year after the infection. Such effects are worsened by factors such as smoking, inadequate education, and chronic diseases. Survivors' families are also affected by the stress and changes they must adapt to. These findings call for integrated care, which encompasses medical, psychological, and social management to address the complex problems of COVID-19 survivors and their families.
