The impact of alternative care pathways adopted during the COVID-19 pandemic on the management of non-communicable diseases at a tertiary care hospital in Thailand.

Background: Management of non-communicable diseases (NCDs), including hypertension (HT) and diabetes mellitus (DM), was significantly impacted by the COVID-19 pandemic. Many institutions adopted alternative care pathways, e.g. pharmacy at home (PAH), and the deferred care (DC). While PAH has been studied for clinical outcomes, evaluation of the DC remains limited. Consequently, this study evaluates both the clinical and economic outcomes of the PAH and DC as alternatives to usual care. Method: A retrospective study was conducted at a tertiary care hospital in Thailand from 1 July 2021, to 30 June 2023. Data from outpatients with HT and DM were classified into PAH, DC, or discharged home with follow-up at the hospital. Clinical outcomes included changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), and fasting blood sugar (FBS), calculated from baseline to follow-up. Economic outcome was the cost of illness (COI) per patient visit. Multivariate multilevel mixed-effects linear regression assessed clinical outcomes, while log-linear regression evaluated economic outcome. Results: There were 3,518 patients in the pandemic period and 4,135 patients in the post pandemic period. There was no statistically significant impact of PAH and DC on changes in SBP, DBP, and FBS. However, both care pathways significantly reduced COI during both periods ( Conclusion: PAH and DC pathways did not worsen the clinical outcomes and reduced costs during and following the pandemic. As a result, these two pathways, developed during the COVID-19 pandemic, can be adapted for regular use. When these pathways are integrated into regular use, they can be promptly and fully reactivated in future emergencies.
