ABSTRACT

57 Figure 1Percentage of patients adherent at each time point over 3 months at each centre and at all centres combined in 2019 compared to 2020 Abbreviations GSTT Guy’s and St Thomas’s Hospital, MH Manchester Hospital, CH Conquest Hospital, MSH Musgrove Park Hospital, DH Derriford Hospial Comparisons assessed using a Chi-square test (*p<0.05, **p<0.01, ***p<0.001). Significant differences between between 2019 and 2020 values denoted by asterisk(s) above the value. Significant differences between 2019 values denoted by a solid line drawn between timepoints compared and asterisk(s) above bar, and similarly significant differences between 2020 values denoted by a dashed line between timepoints compared and asterisk(s) above bar[Figure omitted.

Comparisons assessed using a Chi-square, Mann Whitney U or Kruskal Wallis test (*p<0.05, **p<0.01, ***p<0.001).Discussion3 month adherence rates are low -at best 50%. Rates have changed at some centres since the pandemic, with change varying depending on the treatment pathway modifications implemented.ReferencesWeaver TE & Sawyer AM.
