Direct oral anticoagulant (DOAC) monitoring within primary care: a quality improvement project.

BACKGROUND: Poor monitoring of anticoagulants is a significant area of patient safety. It can lead to the dichotomous risk of haemorrhage/clotting without appropriate counselling and monitoring. While healthcare professionals may be familiar with the anticoagulant warfarin and the international normalised ratio, they might be unaware of the monitoring requirements of direct oral anticoagulants (DOACs), despite DOACs making up 62% of anticoagulants prescribed. The goal of this quality improvement (QI) project was to increase the compliance of monitoring of DOACs within general practice (GP) to improve patient safety and reduce the risk of an adverse outcome for patients. LOCAL PROBLEM: In 2019, the GP surgery had 318 patients prescribed a DOAC and their medication reviews took place opportunistically. While initially, monitoring levels were nearly 100%, by December 2018 this had dropped significantly, and clinicians stated they were unfamiliar with this medication. METHODS AND INTERVENTIONS: This project aimed to resolve this by using QI methodology and Plan-Do-Study-Act (PSDA) cycles to create new sustainable processes with DOAC monitoring and aimed to increase DOAC monitoring by 20% within 6 months. RESULTS: Within 6 months, the project improved the rate of monitoring, and 49% of all patients prescribed a DOAC were seen in a DOAC clinic (n=156) and 78% (n=230/294) had DOAC counselling; 97% (n=295/304) had appropriate blood tests and 72% (n=216/298) had a recent weight recorded within their medical records. Three years on, 600 patients within the practice are prescribed DOACs and 74% (n=445) have had an annual review adhering to the gold standards set within the project. CONCLUSION: This QI project confirms that monitoring of DOACs can be improved within primary care by using QI methodology and improving patient safety, using PDSA cycles, stakeholder engagement and the introduction of the anticoagulant domains within the nationwide Quality Assurance and Improvement Framework.

Aripiprazole long-acting injection - a mirror image study of its effects on hospitalisation at one year.

Second generation antipsychotic long-acting injections have a greater cost than older depots. Their cost-effectiveness has yet to be established. We conducted a non-interventional, observational, follow-up of patients prescribed aripiprazole long-acting injection in two centres using a mirror image method. Data were available for 160 patients consecutively prescribed aripiprazole long-acting injection, of whom 30 were not included in the analysis (21 forensic patients, five incomplete data and four lost to follow-up). Of the 130 patients, 66 (51%) remained on aripiprazole long-acting injection at one year. The mean number of bed days in the year following aripiprazole long-acting injection initiation reduced to 22.82/patient (standard deviation [SD]=55.07) from 30.09/patient/year (SD=30.40) over the three years before initiation ( p<0.001). The mean number of admissions fell from 0.71/patient/year (SD=0.55) to 0.45/patient/year (SD=0.93) over the same period ( p<0.001). The median number of bed days in the three years before aripiprazole long-acting injection was 21.67/year; in the year following it was zero. Outcomes were not statistically better in those who remained on aripiprazole long-acting injection at one year compared with those who discontinued. The prescribing of aripiprazole long-acting injection reduces average bed days and admissions compared with prior treatments. The reduction in bed days is of a magnitude that renders aripiprazole long-acting injection broadly cost-neutral.

Risperidone long-acting injection: a prospective 3-year analysis of its use in clinical practice.

OBJECTIVE: To evaluate outcomes of clinical use of risperidone long-acting injection (RLAI) and determine factors predicting continuation with treatment. METHOD: This prospective, 3-year follow-up of consecutive patients started on treatment with RLAI in normal clinical practice between August 2002 and September 2003 obtained demographic and clinical data from case notes, prescription charts, and hospital computer records. To determine predictors of continuation, a proportional hazards regression (Cox) model was constructed. RESULTS: The study included 211 evaluable patients. Over 3 years, 84% of subjects discontinued RLAI; 27.7% of these switched to oral risperidone. The Cox model showed that younger age (p = .001), longer duration of illness (p = .001), inpatient status at initiation (p = .002), and an RLAI dose of 25 mg/2 weeks (p < .001) predicted greater probability of discontinuation. CONCLUSION: A small proportion of patients initiated on treatment with RLAI continued for 3 years. Outcome is likely to be improved by targeting RLAI treatment at specific patient groups and by using a dose of more than 25 mg/2 weeks.

Outcome following clozapine discontinuation: a retrospective analysis.

BACKGROUND: Clozapine is uniquely effective in refractory schizophrenia, but treatment attrition is high. There has been minimal formal study of the outcomes of stopping clozapine, beyond published observations of the time period immediately after cessation. Our aim was to establish medium-term outcome in patients stopping clozapine in normal clinical practice. METHOD: This study was a retrospective analysis of all subjects registered with Clozaril Patient Monitoring Service and treated in South London and Maudsley National Health Service (NHS) Trust who stopped clozapine between March 2002 and March 2005 after at least 1 year's treatment. Case note review was performed to determine relevant information for 1 year before and 1 year after discontinuation of clozapine, including subject details, reasons for stopping, and clinical outcome 1 year after discontinuation. The primary outcome measure was the Global Assessment of Functioning scale. RESULTS: Thirty-five patients met inclusion criteria. Twelve had died while receiving clozapine. Of those followed up for 1 year after cessation (N = 23), mean Global Assessment of Functioning scores fell by 15 points (95% CI = 6.6 to 24.3; p = .002). Days spent in hospital rose from a mean of 74.1 (SD = 137.3) to 119.8 (SD = 143.5) (p = .214). CONCLUSION: Discontinuation of clozapine has a marked negative impact on clinical status. Death is a common cause of clozapine cessation.
