Practice level decile plots for PINCER prescribing indicators, specifically in relation to (top two rows) gastrointestinal bleeding and (bottom row) cautioned medications. The percentage of patients identified as at risk of potentially hazardous prescribing as measured by each indicator is reported by month. Months are displayed on on the x-axis, starting from September 2019 to September 2021. The median percentage is displayed as a thick purple line and deciles are indicated by dashed purple lines. The month of national lockdown in England as a response to the onset of covid-19 (March 2020) is highlighted with a yellow dashed vertical line. Deciles for CRF and NSAID are calculated across 2546 OpenSAFELY-TPP practices; all other deciles are calculated across 6367 practices (2546 OpenSAFELY-TPP practices plus 3821 OpenSAFELY-EMIS practices). Decile plots for these same indicators, in OpenSAFELY-TPP and OpenSAFELY-EMIS separately, are available in online supplemental figures 1 and 2, respectively. CRF=chronic renal failure; DOAC=direct oral anticoagulants; HF=heart failure; NSAID=non-steroidal anti-inflammatory drugs; PU=peptic ulceration
