Risk of adverse drug events by patient destination after hospital discharge.

PURPOSE: The prevalence of risk factors for adverse drug events (ADEs) in patients discharged from the hospital to various care settings was studied. METHODS: Data on patient risk characteristics for ADEs were collected for hospital discharges for 2000. Differences in the prevalence of 10 risk characteristics among home health care (HHC), self-care (SC), and long-term-care (LTC) patients at the point of discharge were determined. RESULTS: Data for 4250 discharges were analyzed. The three groups differed significantly in the distribution of risk characteristics. HHC patients had the highest prevalence of heart failure, cardiovascular medication use, and polypharmacy, and LTC patients had the highest prevalence of hypoalbuminemia, cognitive impairment, and psychiatric drug use. CONCLUSION: The risk of ADEs in patients discharged to HHC appeared to be comparable to or higher than that in patients discharged to LTC.

Conforming to HIPAA regulations and compilation of research data.

PURPOSE: A set of deidentified patient data compliant with the Health Information Portability and Accountability Act (HIPAA) was compiled, the data lost as a function of unique data elements (UDEs) were measured, and the deidentified data were tested for potential for reidentification. METHODS: After approval by the institutional review board of an integrated health system, a limited-data set was created by querying the health system's pharmacy, administrative, and financial files for patients discharged between January 1 and December 31, 2000. Using the HIPAA "safe-harbor" method, this limited-data set was converted into a deidentified-data table for future statistical analysis, and UDEs in both data sets were identified and quantified. Unique combinations of commonly available data were also identified. RESULTS: The limited-data set, representing 4,738 patient discharges, contained 810,456 UDEs in 322,657 records organized into four data tables (demographics, diagnoses, medication orders, and laboratory test results). The deidentified-data table, representing 4,722 discharges, contained 562,171 UDEs in 128 data-type columns in a single data table. About 31% of the data volume was lost. Much of the information lost was of the type that is of special interest to researchers (e.g., time between episodes of care, ages of >89 years). CONCLUSION: A study suggested that deidentified patient data with a reasonable degree of protection against reidentification were less complete than may be necessary for good research.

Resolution of drug-related problems in home care patients through a pharmacy referral service.

A referral-based, pharmacist-conducted medication management program designed to identify, categorize, and resolve drug-related problems (DRPs) in a home health care (HHC) population was studied. A clinical pharmacy service model was developed to identify patients at high risk for adverse health events resulting from DRPs. Policies and procedures were developed for this service model, including explicit referral criteria, patient-consent documentation, and physician orders. All identified DRPs were categorized, and pharmacist activities relating to the discovery and resolution of DRPs were tabulated. From July 1, 2001, through March 29, 2002, 80 patients were referred for and received clinical pharmacy services, and pharmacists identified 271 DRPs. Every patient referred had a DRP, and 32% of DRPs were identified by a visit to the patient's home. Nearly 65% of pharmacist recommendations were implemented. Using a referral-based practice model in an HHC setting, pharmacists were able to identify and resolve DRPs for every patient referred.

Medicaid prescriber compliance with Joint National Committee VI Hypertension Treatment Guidelines.

BACKGROUND: Since the early 1970s, the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC) has been tasked with the formulation of national guidelines for the management of hypertension. These were significantly changed in 1993 with publication of JNC-5. JNC-6 kept many basic treatment recommendations (i.e., initiation of therapy with a thiazide diuretic or beta-blocker), partly in response to the low adoption rate of the treatment recommendations of JNC-5. OBJECTIVE: To describe single-drug outpatient therapy of hypertension and temporally correlate these therapies with the publication of JNC-5 and JNC-6. METHODS: The electronic records of randomly selected New York State Medicaid recipients without hospitalization who had a diagnosis of hypertension and who were receiving only 1 antihypertensive medication were analyzed for 1994, 1997, and 1999. This analysis identified the medications selected for monotherapy of hypertension and compared these therapies with JNC recommendations. The analysis was correlated to patient comorbidities to further account for provider selection of a non-first-line agent. RESULTS: In 1994, angiotensin-converting enzyme (ACE) inhibitors and calcium-channel blockers accounted for 69% of therapies, with 67.5% of these patients having no JNC-recognized individualizing consideration for their use. In 1999, the combined use of ACE inhibitors and calcium-channel blockers accounted for over 65% of all single-drug therapy; 60% of these patients had no individualizing considerations. Also, in 1999, 47.7% of all patients appeared to be receiving antihypertensive therapies that are not compliant with JNC recommendations. CONCLUSIONS: Single-drug therapy of hypertension in a nonhospitalized New York state Medicaid population from 1994 through 1999 did not closely follow JNC recommendations for the single-agent treatment of hypertension.

Clonidine-induced hypertension in a patient with a spinal lesion.

OBJECTIVE: To report a case of possible clonidine-induced hypertension (by Naranjo score) in a patient with a C4 spinal lesion. BACKGROUND: Clonidine is a medication long used to treat hypertension, and it is still used in the treatment of refractory hypertension. Although effective, clonidine use is hindered by adverse effects and its dual mechanism of action. CASE SUMMARY: A 39-year-old white, quadriplegic man with poorly controlled pain displayed many characteristics consistent with autonomic dysfunction (e.g., C4 spinal lesion, orthostatic hypotension, hypertension). The patient was routinely receiving transdermal clonidine and also received transdermal nitroglycerin paste as needed for control of acute hypertensive episodes. On the recommendation of the home healthcare pharmacists, clonidine was discontinued. Since that time, the patient's blood pressure and the use of emergent antihypertensive treatment have decreased significantly (maximum systolic and diastolic BP by approximately 50 and 25 mm Hg, respectively). CONCLUSIONS: Many of the characteristics of autonomic dysfunction, such as refractory hypertension, can seem selective for the use of clonidine and, because of its reliance on central alpha(2)-activity for its hypotensive effects, clonidine may induce hypertension in patients with autonomic dysfunction. Clonidine should be used with great caution when autonomic dysfunction is suspected.
