PIP prevalence in European community-dwelling older adults is high and depends partially on the data collection method used. Polypharmacy, poor functional status, and depression were identified as the most common risk factors for PIP.

AIMSFew well-designed randomized controlled trials have been conducted regarding the impact of community pharmacist interventions on pharmacotherapeutic monitoring of patients with chronic obstructive pulmonary disease (COPD). We assessed the effectiveness of a pharmaceutical care programme for patients with COPD. METHODSThe pharmaceutical care for patients with COPD (PHARMACOP) trial is a single-blind 3 month randomized controlled trial, conducted in 170 community pharmacies in Belgium, enrolling patients prescribed daily COPD medication, aged ≥50 years and with a smoking history of ≥10 pack-years. A computer-generated randomization sequence allocated patients to an intervention group (n = 371), receiving protocol-defined pharmacist care, or a control group (n = 363), receiving usual pharmacist care (1:1 ratio, stratified by centre). Interventions focusing on inhalation technique and adherence to maintenance therapy were carried out at start of the trial and at 1 month follow-up. Primary outcomes were inhalation technique and medication adherence. Secondary outcomes were exacerbation rate, dyspnoea, COPD-specific and generic health status and smoking behaviour. RESULTSFrom December 2010 to April 2011, 734 patients were enrolled. Forty-two patients (5.7%) were lost to follow-up. At the end of the trial, inhalation score [mean estimated difference (Δ),13.5%; 95% confidence interval (CI), 10.8-16.1; P < 0.0001] and medication adherence (Δ, 8.51%; 95% CI,; P < 0.0001) were significantly higher in the intervention group compared with the control group. In the intervention group, a significantly lower hospitalization rate was observed (9 vs. 35; rate ratio, 0.28; 95% CI, 0.12-0.64; P = 0.003). No other significant between-group differences were observed. CONCLUSIONSPragmatic pharmacist care programmes improve the pharmacotherapeutic regimen in patients with COPD and could reduce hospitalization rates.

BackgroundThe PHARMACOP-intervention significantly improved medication adherence and inhalation technique for patients with COPD compared with usual care. This study aimed to evaluate its cost-effectiveness.MethodsAn economic analysis was performed from the Belgian healthcare payer’s perspective. A Markov model was constructed in which a representative group of patients with COPD (mean age of 70 years, 66% male, 43% current smokers and mean Forced Expiratory Volume in 1 second of % predicted of 50), was followed for either receiving the 3-month PHARMACOP-intervention or usual care. Three types of costs were calculated: intervention costs, medication costs and exacerbation costs. Outcome measures included the number of hospital-treated exacerbations, cost per prevented hospital-treated exacerbation and cost per Quality Adjusted Life-Year. Follow-up was 1 year in the basecase analysis. Sensitivity and scenario analyses (including long-term follow-up) were performed to assess uncertainty.ResultsIn the basecase analysis, the average overall costs per patient for the PHARMACOP-intervention and usual care were €2,221 and €2,448, respectively within the 1-year time horizon. This reflects cost savings of €227 for the PHARMACOP-intervention. The PHARMACOP-intervention resulted in the prevention of 0.07 hospital-treated exacerbations per patient (0.177 for PHARMACOP versus 0.244 for usual care). Results showed robust cost-savings in various sensitivity analyses.ConclusionsOptimization of current pharmacotherapy (e.g. close monitoring of inhalation technique and medication adherence) has been shown to be cost-saving and should be considered before adding new therapies.

Self-reported adherence measured by MARS-5 is inaccurate in identifying nonadherence to inhalation medication in patients with COPD.

A novel explicit screening tool (GheOP³S) was developed to be used for PIP screening in the typical community pharmacy practice.
