Ethnicity, deprivation, and the use of patient portals in England’s general practices 2018-2020

Background

Patient portals are made available and widely promoted in healthcare systems in the USA and Europe. These technologies can help patients access healthcare, receive timely treatment, and manage their health through services such as appointment booking and repeat prescription ordering. However, it is not clear if all patients who need the services are using them. This study explored patient portal use (online appointment booking and repeat prescription ordering features) and patient characteristics among NHS England GP practice patients.

Methods

The study used cross-sectional participant-level data from the GP Patient Survey (GPPS) of 2018, 2019, and 2020. Performing multilevel regression analysis, we explored the association between patient portal feature use and ethnicity and deprivation and controlled for eight other patient characteristics and one GP practice level characteristic, and modelled GP practice as a random effect in the model.

Results

In the fully adjusted model controlled for all patient characteristics and GP characteristics, participants of the Black and Other ethnic groups were less likely to have used online appointment booking (OR: 0.84, 95% CI:0.81, 0.86, and OR: 0.96, 95% CI: 0.92, 0.99, respectively) and online repeat prescription ordering (OR: 0.76, 95% CI: 0.74-0.78 and OR: 0.78, 95% CI: 0.75-0.81, respectively) compared to the White ethnic group. Association with patient portal use increased proportionally with reduced deprivation ranking.

Conclusions

In NHS England GP practices, certain ethnic minority groups and high deprivation ranking is associated with a reduced likelihood of using patient portals. If patient portals are the only route to access services, it is likely to lead to inequalities in use by some patient groups introducing unfair access to the services. Patients could continue to be provided with alternatives to patient portals to prevent potential inequities in access to services.

Key messages

• Patient portals are widely used in the healthcare system and can benefit all patients given that disparities are prevented by understanding patient groups who cannot access portals.

• Understanding patient groups less likely to use patient portals could help adapt healthcare system services and meet the needs of all patient groups.

Effectiveness and safety of pulse oximetry in remote patient monitoring of patients with COVID-19

Context

A surge of COVID cases globally is often portrayed as “very likely”, which overwhelms health systems and challenges their capacities. A mitigation strategy is seen by remotely monitoring COVID patients in out-of-hospital settings to determine the risk of deterioration.

Description of the problem

We need an indicator to enable remote monitoring of COVID patients at home that can be measured by a handy tool; pulse oximetry which measures peripheral blood oxygen saturation (SpO2). Evidence shows that SpO2 is a reliable indicator of deterioration among COVID patients. The UK initiated a national programme (COVID Oximetry @ Home (CO@H)) to assess the theory. The concept can be potentially applied in other countries in various settings. As part of CO@H, we conducted a systematic review of the evidence on the safety and effectiveness of pulse oximetry in remote monitoring of COVID patients.

Results

Our review confirms the safety and potential effectiveness of pulse oximetry in remote home monitoring among COVID patients. We identified 13 research projects involving 2,908 participants that assessed the proposed strategy. Evidence shows the need to monitor at-rest and post-exertional SpO2. At-rest SpO2 of ≤ 92% or a decrease of 5% or more in post-exertional SpO2 should indicate care escalation. The recommended method for measuring at-rest SpO2 is after 5-10 min of rest, and assessing post-exertional SpO2 is after conducting a 1-min sit-to-stand test. We could not find explicit evidence on the impact on health service use compared with other models of care.

Lessons

Remote monitoring of COVID patients could alleviate the pressure on health systems and save hospital resources. Monitoring SpO2 by pulse oximetry can be widely applied, including in resource-limited settings, as the tool is affordable, reliable, and easy to use.

Key messages

• Adopting relevant health technologies in remote patient monitoring is critical to combat the pandemic.

• Pulse oximetry is an affordable, easy to use and widely available tool to monitor patients with COVID-19 at home.

Trends and associated factors for Covid-19 hospitalisation and fatality risk in 2.3 million adults in England

The Covid-19 mortality rate varies between countries and over time but the extent to which this is explained by the underlying risk in those infected is unclear. Using data on all adults in England with a positive Covid-19 test between 1st October 2020 and 30th April 2021 linked to clinical records, we examined trends and risk factors for hospital admission and mortality. Of 2,311,282 people included in the study, 164,046 (7.1%) were admitted and 53,156 (2.3%) died within 28 days of a positive Covid-19 test. We found significant variation in the case hospitalisation and mortality risk over time, which remained after accounting for the underlying risk of those infected. Older age groups, males, those resident in areas of greater socioeconomic deprivation, and those with obesity had higher odds of admission and death. People with severe mental illness and learning disability had the highest odds of admission and death. Our findings highlight both the role of external factors in Covid-19 admission and mortality risk and the need for more proactive care in the most vulnerable groups.

Who is responsible? Defining a hospital catchment population in the English National Health Service

Background

There is a growing emphasis on National Health Service hospitals in England promoting population health. Patients can access any hospital, making it complex to define the population a hospital is responsible for. Defining this 'catchment' population is fundamental to provide a population denominator from which to evaluate service provision such as unmet need and the effect of prevention initiatives. Using Chelsea and Westminster Hospital NHS Foundation Trust (CWFT), a large hospital in London as a case study, methods to define the population that has potential to attend the hospital were compared.

Methods

Inpatient, outpatient and emergency attendances were identified using Hospital Episode Statistics from 1st April 2017-31st March 2018. Lower Layer Super Output Areas (LSOAs), consisting of 1,500 people on average, were used as the geographic unit. Catchment populations were constructed using 3 different methods. Under First-Past-The-Post (FPTP), LSOAs were allocated if a greater proportion of patients attended CWFT than any other hospital trust. Under 30% Proportional Flow (30PF), LSOAs were allocated if more than 30% of patients attended CWFT, while under Stratified Proportional Allocation (SPA), patients were assigned in accordance with the proportion from each LSOA that attended CWFT, by gender and 5-year age strata.

Results

Under FPTP, 30PF and SPA, a total of 303, 326 and 10,636 LSOAs were assigned to CWFT, respectively, with corresponding populations of 530,980, 569,682, and 484,249 and median ages of 36, 36 and 29 years. Under FPTP, the catchment area did not overlap with that of any other hospital, while under 30PF, 13.2% of the LSOAs were also allocated to another hospital catchment. Maps were constructed for FPTP and 30PF.

Conclusions

The 3 methods produced different catchment populations, with differing characteristics. Understanding the relative merits of each method has implications for hospitals in how they engage in and evaluate population health.

Key messages

Engagement in and evaluation of public health activities requires knowledge of ‘who’ the baseline population denominator is, but there is no consensus on determining this at the hospital level. Comparing 3 methods to define a hospital catchment, these differ by total population, median age and geography, the choice of which impacts on how hospitals engage in population health.
