A methodological framework for estimating the clinical and economic value of community pharmacists' clinical interventions using expert opinion.

WHAT IS KNOWN AND OBJECTIVE: Studies of the outcomes of clinical interventions (CIs) performed by community pharmacists are limited. The economic models used in most studies of CIs have been simplistic, often failing to fully capture the counterfactual when estimating savings in health resources resulting from CIs. This paper aimed to describe the complexities involved in estimating the clinical and economic outcomes of CIs performed by community pharmacists when using expert opinion and suggest avenues for improvement. METHODS: Existing models were reviewed, from which a range of key parameters required to evaluate the outcomes of CIs were identified. The considerations necessary to generate potentially more robust estimates of these parameters were discussed. RESULTS AND DISCUSSION: CIs performed by community pharmacists may result in a multitude of effects on numerous health services. By utilizing the approaches described in this paper, researchers working in this field should be able to generate improved estimates of health resource savings and quality of life effects resulting from CIs performed by community pharmacists, when compared to previous efforts. WHAT IS NEW AND CONCLUSION: This article offers recommendations designed to improve the robustness of evaluation when using expert opinion to evaluate CIs performed by community pharmacists.

Inappropriate prescribing in older residents of Australian care homes.

WHAT IS KNOWN AND OBJECTIVE: The incidence of inappropriate prescribing is higher amongst the older age group than the younger population. Inappropriate prescribing potentially leads to drug-related problems such as adverse drug reactions. We aimed to determine the prevalence of inappropriate prescribing in residents of Tasmanian (Australia) residential care homes using Beers and McLeod criteria. METHODS: Patient demographics, medical conditions and medications were collected from medical records. The patients who fulfilled either Beers or McLeod criteria were identified and the characteristics of these patients were then compared. RESULTS: Data for 2345 residents were collected between 2006 and 2007. There were 1027 (43.8%) patients prescribed at least one inappropriate medication. Beers criteria identified more patients (828 patients, 35.3%) as being prescribed inappropriate medication compared with McLeod criteria (438 patients, 18.7%). Patients taking psychotropic medication/s, more than six medications or diagnosed with five or more medical conditions were more likely to be prescribed an inappropriate medication (P<0.001). The most frequently identified inappropriate medications included benzodiazepines, amitriptyline, oxybutynin and non-steroidal anti-inflammatory drugs. WHAT IS NEW AND CONCLUSION: Inappropriate prescribing, as defined by either Beers criteria or McLeod criteria, is relatively common in Australian nursing homes. The prevalence of inappropriate prescribing, and factors influencing it, are consistent with other countries. Both Beers and McLeod criteria are a general guide to prescribing, and do not substitute for professional judgment.
