Physicochemical evaluation of the Upper Litani River watershed, Lebanon.

This study aims to determine the extent of groundwater damage in the Upper Litani River Basin (ULRB) after years of water mismanagement and overfertilization in what is considered to be Lebanon's largest fertile area. Physical and chemical samples were collected between 2005 and 2010 and analyzed using "The Standard Methods for the Examination of Water and Wastewater" (APHA, AWWA) in order to determine the extent of this pollution. The parameters included pH, ammonia, nitrate, nitrite, sulfate, phosphate, dissolved oxygen, and total dissolved solids.

Rating recommendations for consumers about patient safety: sense, common sense, or nonsense?

BACKGROUND: Although many organizations offer advice about the consumer's role in improving patient safety, little is known about these recommendations. METHODS: The Internet and medical literature were searched to identify patient safety recommendations for consumers. Recommendations were classified by type and tabulated by frequency. Nine investigators rated each recommendation for the quality of supporting empirical evidence, magnitude of benefit, and likely patient adherence. For a consumer perspective, 22 relatives of the investigators who were also mothers rated each recommendation. RESULTS: Twenty-six organizations identified 160 distinct recommendations; 115 (72%) addressed medication safety, 37 (23%) advised patients about preparation for hospitalization or surgery, and 18 (11%) offered general advice. Organizations most frequently advised patients to make a list of their medications (92% of organizations), to ask questions about their health and treatment (81%), to enlist an advocate (77%), and to learn about possible medication side effects (77%). Investigators assigned high scores to 11 of the 25 most frequently cited recommendations and to 4 of the 25 least common recommendations. There was little association between the frequency with which recommendations were promulgated and investigators' ratings (r = 0.27, p < .001). Investigators' scores correlated with those of the mothers (r = 0.71, p < .001). DISCUSSION: Contrary to expectation, there was little overlap among the 160 recommendations offered by the 26 organizations. Health care organizations offer many patient safety recommendations of limited value. These organizations should offer a concise and coherent set of recommendations on the basis of evidence, magnitude of benefit, and likely adherence.

Process of care failures in breast cancer diagnosis.

BACKGROUND: Process of care failures may contribute to diagnostic errors in breast cancer care. OBJECTIVE: To identify patient- and provider-related process of care failures in breast cancer screening and follow-up in a non-claims-based cohort. DESIGN: Retrospective chart review of a cohort of patients referred to two Boston cancer centers with new breast cancer diagnoses between January 1, 1999 and December 31, 2004. PARTICIPANTS: We identified 2,275 women who reported > or =90 days between symptom onset and breast cancer diagnosis or presentation with at least stage II disease. We then selected the 340 (14.9%) whose physicians shared an electronic medical record. We excluded 238 subjects whose records were insufficient for review, yielding a final cohort of 102 patients. INTERVENTIONS: None MEASUREMENTS: We tabulated the number and types of process of care failures and examined risk factors using bivariate analyses and multivariable Poisson regression. MAIN RESULTS: Twenty-six of 102 patients experienced > or =1 process of care failure. The most common failures occurred when physicians failed to perform an adequate physical examination, when patients failed to seek care, and when diagnostic or laboratory tests were ordered but patients failed to complete them. Failures were attributed in similar numbers to provider- and patient-related factors (n = 30 vs. n = 25, respectively). Process of care failures were more likely when the patient's primary care physician was male (IRR 2.8, 95% CI 1.2 to 6.5) and when the patient was non-white (IRR 2.8, 95% CI 1.4 to 5.7). CONCLUSIONS: Process failures were common in this patient cohort, with both clinicians and patients contributing to breakdowns in the diagnostic process.

Hospital use of antipsychotic drugs: polytherapy.

OBJECTIVE: Growing acceptance of new psychotropic drugs encouraged a survey of current use of antipsychotic drugs alone and in combinations, with comparisons with previous findings. METHOD: Records from a random sample of McLean Hospital (Belmont, Mass) inpatients treated with an antipsychotic from March to May 2004 were reviewed for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, discharge diagnosis; all current psychotropic drug treatments; initial, peak, and final chlorpromazine-equivalent milligram-per-day dose of antipsychotics (APD); initial, peak, and final lithium-equivalent dose (milligram per day) of mood stabilizers (MS); weight change; clinical status at admission and discharge; and days of hospitalization. RESULTS: In the 305 inpatients sampled (n = 184 women, 60.3%), Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, clinical conditions ranked as follows: major affective (n = 161, 52.8%), psychotic (n = 99, 32.5%), and other disorders (n = 45, 14.8%). Modern drugs comprised 92% of antipsychotic prescriptions, and quetiapine (usually at low doses) was most frequently prescribed. "Polytherapy" (simultaneous treatment with > or =2 psychotropic agents) at discharge was identified in 80% of antipsychotic-treated patients. Use of at least 2 antipsychotics (in 23% of cases) was associated with a 2.8-fold increase in total dose vs monotherapy (651 +/- 403 vs 232 +/- 205 mg/d). Total antipsychotic doses also were higher with mood stabilizer (most often divalproex) or sedative (usually high-potency benzodiazepine) cotreatment, use of older neuroleptics, psychotic-disorder diagnoses, and substance use comorbidity. Polytherapy was not associated with superior clinical improvement or shorter hospitalization but was associated with higher body weight. CONCLUSIONS: Polytherapy involving antipsychotic drugs continues to increase despite limited empirical evidence for greater effectiveness or of safety of such combinations.

Medication reconciliation in ambulatory oncology.

BACKGROUND: Few models for medication reconciliation in ambulatory primary or specialty care have been described, perhaps because of the special challenges posed by this environment. METHODS: Dana-Farber Cancer Institute (Boston) created a reconciliation program that was designed as a patient-clinician partnership intervention. Policies that require clinicians to review and update medication lists at regular appointments were augmented. Clinic assistants printed patients' medication lists from the electronic medical record and distributed lists to established patients for review. Patients provided updated lists to their oncology clinicians. Clinicians then entered the information or indicated changes to be entered by a pharmacist. RESULTS: At baseline, 81% of patients' medication lists included at least one error or omission. With medication reconciliation, 90% of incorrect medication lists were updated. In contrast, only 2% of medication lists were corrected among patients who received "usual" care (p < .001). DISCUSSION: From the program's inception in November 2005 through August 2007, patients and staff reconciled 24,148 medication lists by making 53,040 changes to 168,475 listed drugs, a rate of 31 changes per 100 medications. Implementation required broad staff engagement and ongoing attention to operational issues.

Use of combinations of antipsychotics: McLean Hospital inpatients, 2002.

BACKGROUND: The empirical use of combinations of antipsychotic agents appears to be increasing with little research support for the relative efficacy, safety or cost-effectiveness of this practice. Such treatment was evaluated in hospitalized psychiatric patients. METHODS: Samples of consecutive inpatients treated with > or = 2 ('polytherapy') vs 1 antipsychotic ('monotherapy') were matched on age, sex, diagnosis and admission clinical ratings, and these groups were compared on total daily chlorpromazine-equivalent doses, days in hospital, and changes in clinical ratings between admission and discharge. RESULTS: The study sample included 69 polytherapy and 115 well-matched monotherapy subjects. Despite matching for initial CGI and GAF ratings, polytherapy was associated with high PANSS subscale scores of positive symptoms among affective psychosis, and relatively greater PANSS subscale ratings of excitement-agitation among patients diagnosed with schizophrenia. Estimated clinical improvement during hospitalization was similar among poly- and monotherapy patients, but total daily CPZ-eq doses at discharge averaged twice-greater with polytherapy, and hospitalization lasted 1.5 times longer. CONCLUSIONS: Antipsychotic polytherapy as well as the types of agents combined may reflect clinician responses to particular symptom patterns. The value of specific combinations of antipsychotic agents and their comparison with monotherapies requires specific, prospective, randomized and well-controlled trials that consider matching on clinical characteristics and truly comparable doses across regimens.
