Abstract
The emergence of COVID-19 (SARS-CoV-2) led to distancing measures which acutely affected healthcare infrastructure, leading to limited in-person clinical visits and an increased number of virtual appointments. This study aimed to examine the effects this had on adults with hydrocephalus by describing the lived experiences of a cohort of patients at an outpatient hydrocephalus clinic. Between early May and early July of 2020, remote structured interviews were conducted with participants. Interviews were in-depth and open-ended, allowing participants to reflect and expand on the effects of the social distancing mandate on their well-being and quality of care. Three themes emerged: (1) impacts of changes in treatment provision, (2) impacts of changes in mitigating activities, and (3) impacts of changes on personal well-being. The comprehensive understanding of lived experiences may inform the future provision of healthcare services and social policy. Improved approaches to remote care telemedicine have the potential to facilitate high-quality care.
Introduction
The emergence of COVID-19 (SARS-CoV-2) as a novel coronavirus has led to a marked disruption in the availability and provision of healthcare. By March of 2020, social distancing measures were put in place by provincial and federal bodies. These restrictions specifically extended to healthcare infrastructure: hospitals were a primary point of contact with those most severely infected with COVID-19, primary care physicians were likely to come into contact with those most at risk for developing complications in their clinics, and elective procedures were deemed to put patients as well as physicians at an unnecessary risk for contagion given the required physical proximity. As a result, in-person physician visits were limited to critical and emergency cases, and physicians began scheduling appointments virtually.
Adult hydrocephalus is a neurological condition broadly characterized by a build-up of cerebrospinal fluid inside the ventricles of the brain, leading to potentially dangerous increased pressure on the surrounding tissues (1). In older populations, hydrocephalus has a largely heterogeneous etiology; it is frequently investigated following persistent symptoms, or presents secondary to other disorders such as infection, tumour, or intracranial hemorrhage (2,3). With a lack of non-invasive therapies, the most common treatment for hydrocephalus is surgical implantation of a shunt system which allows the drainage of excess fluid (4). However, shunts are associated with potentially damaging complications in elderly patients such as infection and shunt failure, and may not be an ideal way to treat the condition (5). While the global incidence of hydrocephalus is currently estimated to be 85/100,000, stratified by age it is estimated at 175/100,000 for adults and 400/100,000 for elderly over the age of 80, with incidence expected to rise in areas with an ageing population (6).
Given the complex nature of the condition and the risk of complications requiring ongoing medical care, patients with adult hydrocephalus are at an increased risk of adverse effects and decreased quality of life in the pandemic climate. While agencies such as the Hydrocephalus Association maintain that hydrocephalus has not itself been identified as a risk factor for contracting COVID-19 (7), many patients have had their surgeries postponed indefinitely and their follow-up appointments cancelled or moved to virtual platforms. The aim of the present study is to examine the effects which the pandemic measures and resulting unavailability of clinical care have had on adults with hydrocephalus and their care partners by describing the lived experiences and perspectives of a cohort of patients at an outpatient hydrocephalus clinic.
Methods
A qualitative approach was used to understand the lived experience of people living with hydrocephalus, with a reflexive thematic approach to data analysis used to iteratively develop descriptive emergent themes grounded in experience. Between 11 May and 14 July 2020, remote in-depth interviews were conducted with persons with adult hydrocephalus (and family care partners if they wished to participate) by telephone. It was important for the interviews to take place in the midst of the pandemic so patients could provide detailed accounts of their experiences while social distancing measures were in place and affecting them directly. Participants were patients who consented to be contacted for research prior to attending the University of Calgary Adult Hydrocephalus Clinic (8) at the Foothills Medical Centre in Calgary, Alberta. In 2019, ∼3,000 patients were followed in the Adult Hydrocephalus Clinic, with around 1,500 outpatient assessments and 180 surgical procedures performed. By the end of March 2020, the clinic had suspended in-person specialist appointments and postponed all surgical treatments that were not critical emergencies. Patient contact, recruitment, and data collection were completed by BA, and data analysis was completed by DP and AS, all research staff with experience interacting with patients in this clinical population. Participants had the choice to either sign an online consent form or provide explicit oral consent (which was recorded and transcribed) to participate in the study. The Conjoint Human Research Ethics Board (REB20-0559) at the University of Calgary approved the study. For full details regarding recruitment, data collection, and data analysis, see Subotic et al.

Participant Demographics
A total of 51 potential participants were contacted; of these, 23 patients with non-acute hydrocephalus consented to participate and completed the interview. Patient characteristics are outlined in Table 1. Interviews ranged in length from 19 m:29 s to 1 h:17 m:25 s (mean length = 34 m:44 s, cumulative length = 13 h:18 m:59 s), with 11 females and 12 males aged 37–86 (mean age = 68.7). All participants chose to complete their interviews over the phone.

Thematic Analysis: Patient Perspectives
Three emergent themes were identified, comprehensively characterizing the COVID-19 pandemic's impact on the lived experiences of patients with hydrocephalus (and their care partners). Descriptive codes isolated in the interview data informed the thematic synthesis, and these branched and were combined as similarities between them were detected. The resulting themes are discussed in the following sections, where direct quotes have been edited grammatically solely to improve readability.
Impacts of Changes in Treatment Provision
Results of Treatment Procedure Postponement
One of the main concerns most patients had while adhering to medical social distancing guidelines was the inability to receive the medical procedures and tests for which they had been previously scheduled (Table 2; Subtheme 2.1). This was especially noted by patients who were awaiting shunt implantation and who felt their symptoms were progressively getting worse (namely that their balance and memory were degrading). Similarly, patients who experienced symptoms but were awaiting further testing also expressed their worry at their condition and noted this was exacerbated by the lack of knowing exactly what was wrong. Some patients whose symptoms were deteriorating felt that their concerns were not being taken seriously.

Results of Appointment Changes
Many of the participants had at least one of their regular or follow-up appointments cancelled, and all had experienced at least one telephone appointment with their neurosurgeon. Reactions to virtual appointments were mixed, with patients generally reporting positive experiences if their questions could be answered without a physical examination, and the opposite if they felt the discussion did not thoroughly address their concerns (Table 2; Subtheme 2.2). Patients also seemed concerned that their neurosurgeon may miss important illness cues if they were not assessed in person, and they noted missing the social connection of a face-to-face visit.
Impacts of Changes in Mitigating Activities
Restriction of Access to Physical Activity
Physical activity was mentioned by most participants as either a newly acquired means of dealing with the physical and mental stress of the pandemic, or as something they were no longer able to fully participate in because of closed facilities or deterioration of their physical symptoms (Table 3; Subtheme 3.1). A number of participants used physical exercise as a way to prolong their health, distract from the boredom of being restricted to the home, and spend quality time with a partner they were living with. Participants whose gait and balance symptoms were worsening and prevented movement were especially motivated to visit their neurosurgeon.

Restriction of Access to Social Supports
The inability to interact with social supports – especially loved ones such as family and friends – was one of the most-often mentioned difficulties of coping with the social distancing measures (Table 3; Subtheme 3.2). This was especially evident in participants who lived alone (did not have a significant other who offered emotional and physical support) or who had persons in their lives that were especially susceptible to COVID-19 (such as elderly parents and immune-compromised friends). Patients were often more willing to disregard social distancing measures to interact with their loved ones than to attend in-person clinical appointments and be exposed to the hospital/clinic setting, or wait in crowded pharmacies for their prescriptions.
Impacts of Changes on Personal Well-being
Concerns About Future State of Diagnosis
One of the acute impacts of social distancing measures was the uncertainty of the future of patients’ diagnoses given the uncertainty of when they would be able to resume their regular care. This seemed to more heavily affect those patients with worsening or untreated symptoms, while other patients recognized the uncertainty but were reassured by remote access to their physicians and the efficacy of their current treatments (Table 4; Subtheme 4.1). Patients were more likely to adapt to virtual healthcare if they were less concerned about their prognosis.

Attitudes About Infection Risk
Generally, participants indicated that they took the risk of infection relatively seriously in their day-to-day lives, and minimized unnecessary interaction as much as possible (Table 4; Subtheme 4.2). Participants with more severe symptoms were more likely to self-isolate; however, they were also more likely to risk exposure in-clinic in the effort to ameliorate their condition. Some patients utilized the help of family and friends to run their errands so they did not have to leave their houses, while other patients related scepticism about infection and self-isolated less overall.
Changes in Mental Health
While there was a spectrum of severity, most participants reported at least some impact on their mental health during social distancing measures (Table 4; Subtheme 4.3). Generally, patients who had a live-in support system (usually their spouse) indicated that they noticed increased irritability and restlessness, while patients who reported feeling more isolated noted a marked decline in their mental health, often through increased anxiety and depression. A number of patients who were already being treated for mental illness mentioned asking for an increase in their medication dosage to alleviate their worsening symptoms. Some patients who experienced worsening of their hydrocephalus symptoms directly attributed this to their deteriorating mental health.
Discussion
This single-centre study presents initial evidence about the effects of the COVID-19 pandemic on adults living with hydrocephalus. In-depth interviews allowed participants to openly reflect on their lived experiences as patients with non-acute hydrocephalus while also describing the impacts of the pandemic and its restrictions on their well-being and access to healthcare. The importance of qualitative research within the clinical setting during the COVID-19 pandemic has been previously highlighted, along with the efficacy of qualitative data to provide perspectives which may be missed in epidemiological and clinical research and to inform evidence-based public health responses (10). A number of adverse effects were identified by participants, particularly among those who were awaiting surgical procedures, did not yet have a clear diagnosis, and did not have a familial support system they could rely on. The insights gained from this cohort of patients from an urban, ambulatory hydrocephalus clinic may broadly be applied to similar cohorts in other community-based outpatient clinical settings providing equivalent acute and virtual care.
A significant challenge faced by participants while social distancing measures were imposed on clinics and hospitals was their inability to receive treatment in the form of surgery and post-surgical follow-up. Almost all participants who had previously been booked for one of these procedures either had their appointments cancelled or conducted over the phone, as surgical triage has been imposed limiting most elective surgical procedures (11–14). Only acute hydrocephalus has been identified as a high enough triage tier to warrant immediate surgical intervention (15), and emergent cases of hydrocephalus presenting for surgery have not significantly decreased since the start of the pandemic as have other neurological conditions (16). However, this has little impact on patients with chronic hydrocephalus whose condition does not require emergency intervention. Where physicians are not able to provide patients with treatment due to protocols, increasing the frequency of communications with patients could help mitigate the adverse effects of worsening hydrocephalus symptoms by increasing the levels of perceived access to medical support, and may also ameliorate patient anxiety stemming from uncertainty.
The impact of treatment reduction was made more acute by participants’ restrictions in symptom management. Many participants reported a marked decrease in their regular exercise activities, either due to lack of access to facilities or due to their worsening hydrocephalus symptoms while waiting for treatment. Given that cardiovascular diseases are a common recorded complication in patients treated for hydrocephalus (17,18), the benefits of physical activity (19) may be especially crucial to this population. Worsening symptoms such as gait disturbances, as well as memory impairment and difficulty sleeping, appeared to directly influence participants’ concerns about the future state of their diagnosis. These concerns were more likely to be alleviated during virtual appointments for participants who underwent fewer symptom and lifestyle changes. However, the benefits of virtual support (20) and its appreciation by a majority of participants may generally result in more positive outcomes for patients who receive more of this form of communication from their physicians and healthcare teams.
Similarly, due to social distancing measures, participants’ social connections were also affected and they expressed distress at the long periods of time they were unable to interact with their families, their support groups, or their aid workers. Some reported strain on their relationships with partners who were their caregivers, as the social distancing measures restricted their use of other coping mechanisms and limited their partners’ ability to perform self-care. This supports previous evidence showing that caregiver burden is associated with poorer outcomes (21). Participants were much more likely to report flouting social distancing guidelines to interact with friends and family than to interact with healthcare professionals. Although the increased risk of exposure to COVID-19 in clinical facilities was acknowledged, it was usually seen to be mitigated by the perceived benefits of receiving medical care. Given further awareness of the potential of viral exposure to simply anyone outside the home, this likely presents further evidence of the importance of socialization in this population. While these exacerbated participant experiences align with initial evidence that patients with hydrocephalus require more social support than they currently have access to even outside of pandemic circumstances (22), the impact of socialization on hydrocephalus has not been well-studied, and the physical ramifications of restricted access to support structures remain.
Most participants reported negative changes to their mental health, primarily due to feelings of general isolation (whether they lived alone or were social distancing alongside their care partners) and to exacerbation of symptoms such as difficulty sleeping. These mainly took the form of depressive and anxious episodes, and reflect the documented adverse effects on mental health which have been ascribed to the COVID-19 pandemic (23). However, not all participants reported being negatively affected by this changeIt is unclear whether this is due to the apathy previously reported in hydrocephalus patients in similar situations (24), or due to supports available to these participants. While general strategies have been proposed to alleviate the impact of the pandemic on patient mental health (25), the relationship between hydrocephalus and mental health has not been well examined and it is unclear whether they would be helpful to this population. This study presents cursory evidence of enduring comorbidities which should be further explored.
Strengths and Limitations
These findings provide promising avenues for future research, particularly as they have been described by adult patients with hydrocephalus themselves. A strength of this study was the ability to complete the participant interviews and gather data on lived experiences during the height of the public health measures and resulting impacts, while they were being experienced. Participants were able to give details about how they were impacted by pandemic measures as they were occurring, and were able to describe different healthcare experiences, such as telephone appointments, soon after having had them. Conducting semi-structured interviews until theoretical saturation was achieved allowed participants to identify and reflect on their most relevant healthcare and lifestyle experiences, while probing more into the recurring and most challenging factors mentioned by a majority of the participants. As well, while relatively little comparable research has been undertaken, the themes synthesized from the interviews do align with some previous work discussing the impact of various aspects of hydrocephalus treatment and prognosis on patient outcomes and general quality of life (26,27).
A limitation of the study is that, by necessity, only those hydrocephalus patients who were well enough to participate in an interview lasting 30 to 60 min were recruited, excluding those patients who may have been more severely impacted or even hospitalized as a consequence of the pandemic. Similarly, due to the pandemic restrictions, we were unable to perform any clinical evaluations of the participants such as cognitive or gait assessments which, while not within the scope of the present study, would have provided a robust corroborating dataset. However, virtual adaptations to assessments such as the one utilized in this study may provide useful avenues for future service provision or research participation in which in-person attendance is not possible. Another limitation is that participants were patients recruited from a single specialty outpatient hydrocephalus clinic, which was located in an urban location and funded within a single-payer healthcare system. As a result, findings may not be representative of the experiences of hydrocephalus patients seeking treatment in multi-payer systems or less populous areas with more limited access to specialized treatment. It is worth noting, however, that a number of participants did reside in rural areas which, while still serviced by this outpatient clinic, did routinely face more challenges to their care such as needing to travel a considerable distance to be seen by their specialist, or needing to rely on telehealth for routine appointments.
Clinical Implications
The in-depth understanding of the lived experiences of community-based patients with hydrocephalus limited by decreased social engagement and restricted healthcare access may inform the future provision of healthcare services and information, in addition to social policy. This body of evidence may help mitigate the effect on patients of future pandemics or anticipated future waves of COVID-19, or other major incidents or emergencies, where similar conditions would occur. The reported adverse consequences of the inability to receive surgical treatment and follow-up post-intervention are important for treatment planning and support during social distancing. The underscoring of the negative effects on patient wellbeing of uncertainty (especially with respect to prognosis and treatment planning), isolation, and perceived indifference of the medical system, alongside the willingness to adopt virtual care when it cannot be provided in person, point to a solution which has the potential to be widely implemented. When access to surgical treatment cannot be made possible, improved and innovative approaches to remote care and virtual medicine, with an emphasis on maintaining an open and supportive dialogue between physician and patient, have the potential to facilitate high-quality care which at the very least may alleviate the additional stress and uncertainty felt by the patient.
Ultimately, the identified themes are limited to the impacts of the initial few months of the COVID-19 pandemic. Additional qualitative work documenting how the patient impact changes as the pandemic continues and how the public healthcare response evolves in response to emergent challenges would be beneficial, as would further studying the personal and long-term impacts of living with the condition in its multitude of forms. Relatively little research has been done to date on the acute and enduring impacts on the quality of life of adults with hydrocephalus, especially where it does not relate directly to post-surgery outcomes (8) and specific treatment prognoses. Future research in this area may benefit a more heterogeneous population dealing with the varied aetiology of hydrocephalus.
