A pharmacy-based approach to cholesterol management.

OBJECTIVE: To determine the clinical and economic impact of a pharmacy-based cholesterol management program in patients with cardiovascular disease. STUDY DESIGN: Demonstration project. PATIENTS AND METHODS: From January 1, 1999, through June 30, 1999, 300 patients with a documented history of cardiovascular disease were enrolled in a pharmacy-based cholesterol program. A similar group of 150 randomly selected patients receiving usual care during the same period served as the comparator group. The following were collected for both groups: patient demographics, comorbidities, fasting lipid profiles, cholesterol medication, cost of medication, and cardiovascular events. The McNemar symmetry chi2 test was used to compare appropriate laboratory monitoring, receipt of cholesterol medication, and achievement of target low-density lipoprotein cholesterol levels at baseline and 1 year for both groups. Kruskal-Wallis analysis of variance was used to compare the cost of therapy for both groups at baseline and follow-up. RESULTS: Mean +/- SD age of program and usual care patients was 67 +/- 10 and 69 +/- 11 years, respectively. At 1 year, >95% of program patients were receiving appropriate laboratory monitoring. In 1 year, the percentage of patients reaching target low-density lipoprotein cholesterol levels increased from 45% to 72% (P< .01) and from 33% to 43% (P = .26) in program and usual care patients, respectively. Despite increased medication use among program patients, their cost per patient per month was lower at 1-year follow-up vs baseline. CONCLUSION: Regular patient interaction and close patient monitoring allowed the pharmacy-based lipid management program to improve cholesterol management in patients with cardiovascular disease.

Chest pain: overlooked manifestation of unsuspected esophageal foreign body.

Two cases of unsuspected esophageal foreign body ingestion with chest pain as the main symptom are reported. Both patients had extensive cardiac evaluation to rule out myocardial ischemia. They were discharged home with continuing chest pain and odynophagia. Both patients were denture wearers, and further questioning revealed the coincidence of chest pain with taking meals. Further evaluation revealed an impacted esophageal foreign body in one patient and an esophageal perforation with a mediastinal abscess in the other. These cases illustrate the importance of considering esophageal foreign bodies as factors in chest pain.

Incidence of pancreatitis in patients undergoing sphincter of Oddi manometry (SOM).

OBJECTIVE: Sphincter of Oddi manometry (SOM) is a useful diagnostic procedure when evaluating patients with unexplained biliary pain or idiopathic recurrent pancreatitis. Acute pancreatitis is a recognized complication of SOM whose pathogenesis appears to be multifactoral. We conducted this study to determine the incidence of pancreatitis in patients after SOM and to identify any variables that may lead to an increased incidence of pancreatitis. METHODS: A retrospective review of 100 consecutive patients who underwent SOM between 1992 and 1996 at two university-affiliated hospitals was done. SOM was performed using a triple lumen catheter with each lumen perfused at a rate of 0.25 cc/min using an Arndorfer pneumohydraulic capillary perfusion system. The following data were recorded: age, gender, clinical type of sphincter of Oddi dysfunction, length of procedure, doses of medications used, duct cannulated, sphincter of Oddi pressure, whether endoscopic retrograde cholangiopancreatography (ERCP) with or without sphincterotomy was performed, and the number of patients developing pancreatitis. Statistical analysis was performed using a T test, chi2, and multiple regression analysis. RESULTS: The overall incidence of pancreatitis was 17%. Six patients with type II SO dysfunction and 11 patients with type III SO dysfunction developed pancreatitis. The incidence of pancreatitis was significantly lower in those patients who only had SOM, compared with those patients who had SOM and ERCP (9.3% vs 26.1%, p < 0.026). There was no significant correlation between age, gender, duration of procedure, dose of midazolam used, sphincter of Oddi pressure, or type of SO dysfunction with the development of SOM-induced pancreatitis. Multiple regression analysis showed that sphincterotomy added no additional risk, beyond that associated with ERCP, for the development of pancreatitis. CONCLUSIONS: The results of this study indicate that the incidence of pancreatitis was highest when SOM was followed by ERCP. A potential method of decreasing the incidence of pancreatitis after SOM is performing ERCP with or without sphincterotomy at another session, separated from the SOM by at least 24 h. Before this can be definitely recommended, the results of this study must be validated by others or by a prospective study.
