Background: During the pandemic, there have been disruptions to how patients seek care. Research design and methods: To investigate monthly prescription claims for asthma and chronic obstructive pulmonary disease (COPD) medicines during the first UK wave, interrupted time series (ITS) analysis was used. A national cohort of community patients' data were examined. Results: Descriptive statistics show salbutamol, aminophylline, ipratropium, and theophylline remain below pre-pandemic levels. Montelukast showed pre-pandemic monthly increase (Est. 67,151 doses, P = 0.05, 95% CI: 1011, 133,291), followed by a jump of 1.6 million doses at March , followed by monthly declines (Est. −112,098 doses, P = 0.216, 95% CI: -293,499, 69,303). Before the pandemic, tiotropium, salbutamol, aminophylline, and ipratropium (P = 0.003) show monthly declines but theophylline and beclometasone showed increases. In March , salbutamol (P = 0.033) and ipratropium (P = 0.001) show a significant jump. After March , ipratropium continues with a downward trajectory (P = 0.001), with a generalized negative trend for all other agents. Salbutamol confidence bounds become negative after March 2020. Some brands were unavailable. Conclusions: An 'unmet' medical gap is identified. While it is essential to understand the underlying reasons, urgent action needs to be taken to reassess patients and ensure continuity of care.
