Fixed-Dose Combination Antidiabetic Therapy: Real-World Factors Associated with Prescribing Choices and Relationship with Patient Satisfaction and Compliance
Improving management of hypertension in general practice: a randomised controlled trial of feedback derived from electronic patient data
Background
Although absolute risk of death associated with raised blood pressure increases with age, the benefits of treatment are greater in older patients. However, fewer patients in this group are identified, treated, and controlled.
Aim
To evaluate the impact of the provision of different levels of feedback on identification, treatment, and control of older patients with hypertension.
Design of study
Randomised controlled trial.
Setting
Fifty-two Scottish general practices.
Method
Practices were randomly allocated to either control (n = 19), audit only feedback (n = 16), or audit plus risk feedback, prioritising patients by absolute risk (n = 17). Electronic data were extracted from practice computer systems annually from 1999 to 2001 and used to develop feedback. Data were collected for 30 345 patients aged 65–79 years.
Results
The majority of known patients with hypertension in each group had an initial blood pressure recorded (control = 89.6%; audit = 80.4%; risk = 96.1%) and this increased over the study period (control = 92.3%; audit = 86.0%; risk = 96.6%). Initially, more than 80% of patients in each group were treated but many were uncontrolled (blood pressure ≥160/≥90mmHg) (control = 41.5%; audit = 41.3%; risk = 36.1%). The numbers of untreated and uncontrolled patients in each group reduced (control = 32.3%; audit = 38.3%; risk = 32.6%). There was some evidence of a significant difference in mean systolic pressure between the audit plus risk and audit only groups: (149.6 versus 152.7 mmHg; P = 0.019) and of significantly greater control in the audit plus risk group compared with the other groups 49.4% (versus audit only = 35.4%; versus control = 46.5%; odds ratio = 1.72 [95% confidence interval = 1.09 to 2.70]; P = 0.019).
Conclusions
Levels of identification, treatment, and control improved in each group. Although there were still significant numbers of patients with uncontrolled hypertension, there is some evidence to suggest that providing patient-specific feedback may have a positive impact on identification and management of hypertension in older people and produce an increase in control

<p>OBJECTIVE: Aspirin is associated with a reduced risk of developing colorectal cancer. This study examined whether patients with colorectal cancer prescribed aspirin had improved survival.</p>
<p>DESIGN: An observational population cohort study was undertaken using data linkage of cancer registry, dispensed prescriptions and death certificate records in Tayside, Scotland. All community prescribed aspirin pre- and post-diagnosis was extracted and periods of aspirin use post-diagnosis for each individual were analysed using Cox proportional hazard models. Main outcome measures were all-cause and colorectal mortality from death certificates.</p>
<p>RESULTS: Two thousand nine hundred ninety patients were identified with colorectal cancer between 1st January 1997 and 30th December 2006 and followed up until 28th February 2010. Median age at diagnosis was 73 (interquartile range [IQR] 65-80) with 52% male. One thousand nine hundred ninety-eight (67%) deaths were recorded with 1021 (34%) attributed to colorectal cancer. One thousand three hundred forty (45%) patients used aspirin at some stage of the study period. Aspirin use post-diagnosis was associated with lower risk of all cause mortality (hazard ratio [HR]=0.67, 95% confidence interval [CI]=0.57-0.79, p<0.001) and colorectal cancer specific mortality after allowing for age, Dukes' stage, gender, socio-economic status and aspirin use pre-diagnosis. Increasing age and stage at diagnosis were associated with increased risk, with more affluent patients at reduced risk.</p>
<p>CONCLUSIONS: Our study suggests that aspirin use post-diagnosis of colorectal cancer may reduce both all cause and colorectal cancer specific mortality. However further work is required to ensure this is a causal relationship and to identify whether it is best used in specific groups of patients.</p>
