Drug-related problems in patients with benign prostatic hyperplasia: a cross sectional retrospective study

Benign Prostatic Hyperplasia (BPH) patients are at risk of acquiring drug-related problems (DRPs), as it is present in the majority of aging men. To date, DRPs among BPH patients have not been well studied. We conducted this retrospective study in a tertiary hospital in Malaysia from January 2009 to June 2012 with the aim of identifying the factors associated with DRPs among BPH patients. The Pharmaceutical Care Network Europe Classification Version (PCNE) 5.01 was used as a tool to classify DRPs. We enrolled 203 patients from 259 hospital admissions. A total of 390 DRPs were found and there was an average of 1.5±1.3 problems per hospitalization. 76.1% of hospital admissions included at least one DRP. The most common DRP categories encountered were drug choice problems (45.9%), drug interactions (24.9%), and dosing problems (13.3%). Factors such as advanced age (p = 0.005), a hospital stay of more than 6 days (p = 0.001), polydrug treatments (p<0.001), multiple comorbidities (p<0.001), and comorbid cardiovascular disease (p = 0.011), diabetes mellitus(p = 0.001), hypertension (p<0.001) and renal impairment (p = 0.011) were significantly associated with the occurrence of DRPs. These data indicated that the prevalence of DRPs is high among BPH patients. The identification of different subtypes of DRPs and the factors associated with DRPs may facilitate risk reduction for BPH patients.

Extrahepatic conditions and hepatic encephalopathy in elderly patients

PURPOSE

Extrahepatic conditions can cause, exacerbate, or mimic hepatic encephalopathy in any patient with advanced liver disease, particularly in older persons. The aim of this study was to characterize the clinical features and frequency of extrahepatic conditions and the effect of therapeutic interventions upon the encephalopathy.

DESIGN

Survey.

SETTING

Inner city community hospital.

METHODS

Retrospective chart review of 294 elderly patients (age 65-97) with liver disease and suspected hepatic encephalopathy, during a 15-year period, that included 188 men and 106 women.

RESULTS

Extrahepatic conditions were found in 64 patients (22%); 29 (10%) patients had > 1 extrahepatic condition. Category and frequency of the extrahepatic conditions found in these 64 patients were as follows: urinary tract infection, 21 (33%); cellulitis/infected pressure ulcers, 16 (25%); pneumonia, 16 (25%); septicemia (with positive blood cultures), 10 (16%); silent myocardial infarction, 10 (16%); drug toxicity (nonsteroidal anti-inflammatory drugs, sedatives, hypnotics, antidiabetics), 6 (9%); meningitis, 6 (9%); head injury, 5 (8%); stroke, 5 (8%); and subdural hematoma, 5 (8%).

CONCLUSION

A significant proportion of elderly patients with liver disease and presumptive diagnosis of hepatic encephalopathy may have extrahepatic condition(s), and the treatment of the latter may improve clinical outcome of such patients. A high index of suspicion, low threshold of diagnostic measures, and prompt treatment of any associated extrahepatic condition are essential to prevent significant morbidity and mortality of these patients.
