The purpose of this study was to evaluate the implementation of inclisiran in a regional primary care setting in the UK Inclisiran, also known as KJX839, is a medication made to reduce the level of "bad" cholesterol (LDL-cholesterol) in the blood. Inclisiran works in a way that makes the liver produce less of a substance called 'PCSK9'. PCSK9 reduces the ability of the liver to remove LDL-cholesterol from the blood. By lowering the production of PCSK9, Inclisiran leads to more LDL-cholesterol being removed by the liver from the blood, thereby reducing LDL-cholesterol overall.
A phase IIIb, multicenter, randomized controlled study to evaluate the implementation, preference, and utility for administration of inclisiran sodium in participants on established lipid lowering medication or, have been recommended lipid lowering therapy by their healthcare provider but are unable to tolerate treatment, with elevated low density lipoprotein cholesterol (LDL-C) in a primary care population. This study was an implementation research study that utilized implementation science methodology and use of the electronic medical record (EMR). Using implementation science methodology, the study intended to assess the effect of 9 months treatment with inclisiran with/without behavioural support, compared to standard of care + behavioural support, on LDL-C reduction, total lipid profile, assessments of patient and healthcare professional (HCP) satisfaction, health-care resource utilization and healthcare service process evaluation. The primary focus of this study was implementation and 'transactability' - how to organize, deliver and maintain an innovative treatment for Atherosclerotic Cardiovascular Disease (ASCVD) in a primary care setting in a sustainable way. Patients taking part in the study were randomised to one of three groups: * Control + BS: Participants continued to receive their background lipid lowering therapy plus behavioural support. Subjects in treatment group 1 were referred to as the control group in this study * Inclisiran: Participants continue to receive their background lipid lowering therapy, plus inclisiran for injection (delivered in an injection-only model). * Inclisiran + BS: Participants continued to receive their background lipid lowering therapy, plus inclisiran for injection, plus behavioural support. Participants who were randomized to Inclisiran or Inclisiran + BS received one injection of inclisiran on Day 1 and a second injection of inclisiran on Day 90. Participants in Control + BS and Inclisiran + BS received a monthly telephone call from a health advisor, providing support to enable participants to make positive behaviour changes to reduce their cardiovascular risk.

Percentage Change in LDL-C From Baseline to Day 270
Change in Low Density Lipoprotein Cholesterol (LDL-C) after 270 days of treatment in adults on established lipid lowering medication or who have been recommended lipid lowering therapy by their health care provider but are unable to tolerate treatment, regardless of treatment discontinuation for any reason and regardless of unforeseen change in the concomitant lipid lowering therapy. Multiple imputation is used to impute missing data using a washout model.
Time frame: Baseline, Day 270
Number of Participants Interviewed for CFIR Analysis.
To identify the need to support the implementation of inclisiran in the real world, a framework was drawn known as the Consolidated Framework for Implementation Research (CFIR). Patients who received inclisiran were interviewed to understand their experience with the program and to obtain a comprehensive understanding, with or without behavioural support. These patients were interviewed on various aspects of their experience related to their high cholesterol management, trial participation, inclisiran injections, attending appointments, and if applicable their experience with the behavioural support programme. These interviews were not set up in a way that allow numerical analysis. The process evaluation was conducted by Manchester University.

Patient Reported Outcomes: CSQ-8 Total Score After Treatment
The Client Satisfaction Questionnaire (CSQ)-8 is the standard self-administered CSQ scale containing 8 items that comprise the measurement of satisfaction with services and measurement of improvement of capacity to cope and change adaptively. Items include questions enquiring about respondents' opinions and conclusions about services they have received or are currently receiving. Response options differ from item to item, but all are based on a four-point scale. For the CSQ-8 version, scores range from 8 to 32, with higher values indicating higher satisfaction.

Patient Reported Outcomes: CSQ-8 Total Score Between Inclisiran Arms
The CSQ-8 is the standard self-administered CSQ scale containing 8 items that comprise the measurement of satisfaction with services and measurement of improvement of capacity to cope and change adaptively. Items include questions enquiring about respondents' opinions and conclusions about services they have received or are currently receiving. Response options differ from item to item, but all are based on a four-point scale. For the CSQ-8 version, scores range from 8 to 32, with higher values indicating higher satisfaction. This secondary outcome only analysed data of the two Inclisiran arms, by considering the Inclisiran only arm as the control group. The standard error for Least Square Mean could change because dropping a treatment arm affects the estimation of treatment effects and the variability of data.

Change From Baseline to Day 90 in Total PAM Score
The Patient Activation Measure (PAM) questionnaire is a survey that assesses a person's underlying knowledge, skills and confidence integral to managing his or her own health and healthcare. This study used the 13-point PAM questionnaire, which consists of 13 statements relating to patients beliefs about health care, confidence in their management of health related tasks, and self-assessed knowledge of their condition. For each statement patients are required to say how much they either agree or disagree on a response scale of 1-5, where 1 represents "strongly disagree", 4 represents "strongly agree" and 5 indicates that the statement is "not applicable" to them. A standardised spreadsheet in excel is used to score the PAM. Responses are used to generate a continuous score from 0 to 100 where higher scores indicate that the patient is more activated.

This outcome only analysed data of the two inclisiran arms, by considering the Inclisiran only arm as the control group. In an ANCOVA model, the Least Squares Means and corresponding Standard Error could change because the removal of a treatment group affects the estimation of the treatment effects and the adjustment for the covariate(s).

Measures of Adherence to Cardiovascular Disease Self-management Using the Validated Patient Activation Measure (PAM) Questionnaire.
The Patient Activation Measure (PAM) questionnaire is a survey that assesses a person's underlying knowledge, skills and confidence integral to managing his or her own health and healthcare. This study used the 13-point PAM questionnaire, which consists of 13 statements relating to patients beliefs about health care, confidence in their management of health related tasks, and self-assessed knowledge of their condition. For each statement patients are required to say how much they either agree or disagree on a response scale of 1-5, where 1 represents "strongly disagree", 4 represents "strongly agree" and 5 indicates that the statement is "not applicable" to them. Responses are used to generate a continuous score from 0 to 100. The continuous PAM scores are then categorised into 4 levels: Level 1 - disengaged and overwhelmed; Level 2 - become aware but still struggling; Level 3 - taking action; Level 4 - maintaining behaviors and pushing further.
