Item Open Access Impact of COVID-19 on perceived wellbeing, self-management and views of novel modalities of care among medically vulnerable patients in Singapore.(Chronic illness, 2021-12-29) Yoon, Sungwon; Hoe, Pei Shan; Chan, Angelique; Malhotra, Rahul; Visaria, Abhijit; Matchar, David; Goh, Hendra; Seng, Bridget; Ramakrishnan, Chandrika; Koh, Mariko S; Yee, Tiew Pei; Nadarajan, Gayathri Devi; Bee, Yong Mong; Graves, Nicholas; Jafar, Tazeen H; Ong, Marcus EhObjectives
This study aims to examine the impact of COVID-19 measures on wellbeing and self-management in medically vulnerable non-COVID patients and their views of novel modalities of care in Singapore.Methods
Patients with cardiovascular disease (CVD), respiratory disease, chronic kidney disease, diabetes and cancer were recruited from the SingHealth cluster and national cohort of older adults. Data on demographics, chronic conditions and perceived wellbeing were collected using questionnaire. We performed multivariable regression to examine factors associated with perceived wellbeing. Qualitative interviews were conducted to elicit patient's experience and thematically analyzed.Results
A total of 91 patients participated. Male patients compared with female patients perceived a lower impact of the pandemic on subjective wellbeing. Patients with CVD compared to those having conditions other than CVD perceived a lower impact. Impacts of the pandemic were primarily described in relation to emotional distress and interference in maintaining self-care. Hampering of physical activity featured prominently, but most did not seek alternative ways to maintain activity. Despite general willingness to try novel care modalities, lack of physical interaction and communication difficulties were perceived as main barriers.Discussion
Findings underline the need to alleviate emotional distress and develop adaptive strategies to empower patients to maintain wellbeing and self-care.Item Open Access Spillover Effects of COVID-19 on Essential Chronic Care and Ways to Foster Health System Resilience to Support Vulnerable Non-COVID Patients: A Multistakeholder Study.(Journal of the American Medical Directors Association, 2021-11-12) Yoon, Sungwon; Goh, Hendra; Chan, Angelique; Malhotra, Rahul; Visaria, Abhijit; Matchar, David; Lum, Elaine; Seng, Bridget; Ramakrishnan, Chandrika; Quah, Stella; Koh, Mariko S; Tiew, Pei Yee; Bee, Yong Mong; Abdullah, Hairil; Nadarajan, Gayathri Devi; Graves, Nicholas; Jafar, Tazeen; Ong, Marcus EHObjectives
Little empirical research exists on how key stakeholders involved in the provision of care for chronic conditions and policy planning perceive the indirect or "spillover" effects of the COVID-19 on non-COVID patients. This study aims to explore stakeholder experiences and perspectives of the impact of COVID-19 on the provision of care for chronic conditions, evolving modalities of care, and stakeholder suggestions for improving health system resilience to prepare for future pandemics.Design
Qualitative study design.Setting and participants
This study was conducted during and after the COVID-19 lockdown period in Singapore. We recruited a purposive sample of 51 stakeholders involved in care of non-COVID patients and/or policy planning for chronic disease management. They included health care professionals (micro-level), hospital management officers (meso-level), and government officials (macro-level).Methods
In-depth semi-structured interviews were conducted. All interviews were digitally recorded, transcribed verbatim, and thematically analyzed.Results
Optimal provision of care for chronic diseases may be compromised through the following processes: lack of "direct" communication between colleagues on clinical cases resulting in rescheduling of patient visits; uncertainty in diagnostic decisions due to protocol revision and lab closure; and limited preparedness to handle non-COVID patients' emotional reactions. Although various digital innovations enhanced access to care, a digital divide exists due to uneven digital literacy and perceived data security risks, thereby hampering wider implementation. To build health system resilience, stakeholders suggested the need to integrate digital care into the information technology ecosystem, develop strategic public-private partnerships for chronic disease management, and give equal attention to the provision of holistic psychosocial and community support for vulnerable non-COVID patients.Conclusions and implications
Findings highlight that strategies to deliver quality chronic care for non-COVID patients in times of public health crisis should include innovative care practices and institutional reconfiguration within the broader health system context.Item Open Access Validation and application of a needs-based segmentation tool for cross-country comparisons.(Health services research, 2021-12) Duminy, Lize; Sivapragasam, Nirmali Ruth; Matchar, David Bruce; Visaria, Abhijit; Ansah, John Pastor; Blankart, Carl Rudolf; Schoenenberger, LukasObjective
To compare countries' health care needs by segmenting populations into a set of needs-based health states.Data sources
We used seven waves of the Survey of Health, Aging and Retirement in Europe (SHARE) panel survey data.Study design
We developed the Cross-Country Simple Segmentation Tool (CCSST), a validated clinician-administered instrument for categorizing older individuals by distinct, homogeneous health and related social service needs. Using clinical indicators, self-reported physician diagnosis of chronic disease, and performance-based tests conducted during the survey interview, individuals were assigned to 1-5 global impressions (GI) segments and assessed for having any of the four identifiable complicating factors (CFs). We used Cox proportional hazard models to estimate the risk of mortality by segment. First, we show the segmentation cross-sectionally to assess cross-country differences in the fraction of individuals with different levels of medical needs. Second, we compare the differences in the rate at which individuals transition between those levels and death.Data collection/extraction methods
We segmented 270,208 observations (from Austria, Belgium, Czech Republic, Denmark, France, Germany, Greece, Israel, Italy, the Netherlands, Poland, Spain, Sweden, and Switzerland) from 96,396 individuals into GI and CF categories.Principal findings
The CCSST is a valid tool for segmenting populations into needs-based states, showing Switzerland with the lowest fraction of individuals in high medical needs segments, followed by Denmark and Sweden, and Poland with the highest fraction, followed by Italy and Israel. Comparing hazard ratios of transitioning between health states may help identify country-specific areas for analysis of ecological and cultural risk factors.Conclusions
The CCSST is an innovative tool for aggregate cross-country comparisons of both health needs and transitions between them. A cross-country comparison gives policy makers an effective means of comparing national health system performance and provides targeted guidance on how to identify strategies for curbing the rise of high-need, high-cost patients.
