Evaluation of poison information services provided by a new poison information center.

AIM: The aim of this study is to assess the nature and quality of services provided by poison information center established at a tertiary-care teaching hospital, Mysore. SETTINGS AND DESIGN: This was a prospective observational study. MATERIALS AND METHODS: The poison information center was officially established in September 2010 and began its functioning thereafter. The center is equipped with required resources and facility (e.g., text books, Poisindex, Drugdex, toll free telephone service, internet and online services) to provide poison information services. The poison information services provided by the center were recorded in documentation forms. The documentation form consists of numerous sections to collect information on: (a) Type of population (children, adult, elderly or pregnant) (b) poisoning agents (c) route of exposure (d) type of poisoning (intentional, accidental or environmental) (e) demographic details of patient (age, gender and bodyweight) (f) enquirer details (background, place of call and mode of request) (g) category and purpose of query and (h) details of provided service (information provided, mode of provision, time taken to provide information and references consulted). The nature and quality of poison information services provided was assessed using a quality assessment checklist developed in accordance with DSE/World Health Organization guidelines. STATISTICAL ANALYSIS: Chi-Square test (χ(2)). RESULTS: A total of 419 queries were received by the center. A majority (n = 333; 79.5%) of the queries were asked by the doctors to provide optimal care (n = 400; 95.5%). Most of the queries were received during ward rounds (n = 201; 48.0%), followed by direct access (n = 147; 35.1%). The poison information services were predominantly provided through verbal communication (n = 352; 84.0%). Upon receipt of queries, the required service was provided immediately (n = 103; 24.6%) or within 10-20 min (n = 296; 70.6%). The queries were mainly related to intentional poisoning (n = 258; 64.5%), followed by accidental poisoning (n = 142; 35.5%). The most common poisoning agents were medicines (n = 124; 31.0%). The service provided was graded as "Excellent" for the majority of queries (n = 360; 86%; P < 0.001), followed by "Very Good" (n = 50; 12%) and "Good" (n = 9; 2%). CONCLUSION: The poison information center provided requested services in a skillful, efficient and evidence-based manner to meet the needs of the requestor. The enquiries and information provided is documented in a clear and systematic manner.

Helicobacter pylori associated vitamin B12 deficiency, pernicious anaemia and subacute combined degeneration of the spinal cord.

A 23-year-old man presented with weakness in the lower limbs, numbness in hands and feet over past 6 months. Examination revealed a combination of absent ankle jerk, extensor plantar response and reduced sensations in a glove and stocking distribution. MRI of the spinal cord was distinctive of subacute combined degeneration (SACD) of the spinal cord. Serum vitamin B12 was low and anti-intrinsic factor antibodies were positive. A biopsy of the stomach revealed intense inflammatory infiltrates in lamina propria with grade III Helicobacter pylori infection. Other work-up for the cause of vitamin B12 deficiency was unremarkable. H pylori infection triggers autoantibodies by a mechanism of molecular mimicry. This case report highlights H pylori as a causative agent in vitamin B12 deficiency and culminating in SACD of the spinal cord. H pylori treatment reverses the underlying pathogenesis and corrects vitamin B12 deficient state in selected individuals.

Prevalence of medication-related problems among patients with renal compromise in an Indian hospital.

WHAT IS KNOWN AND OBJECTIVE: Patients suffering from renal dysfunction often have multiple medical conditions either as a cause or as a consequence of their renal disease. These patients receive an average of 10-12 medications daily leading to complex dosing schedules and are more likely to develop medication-related problems (MRPs). The objectives of this study were to determine the nature and extent of MRPs in renally compromised patients and to explore the potential clinical significance of the MRPs. The potential for a clinical pharmacist to contribute towards resolving or preventing some of these MRPs was also explored. METHODS: A prospective study was conducted for a period of 9 months in the renal unit of Jagadguru Shri Shivaratheeshwara (JSS) Medical College Hospital, Mysore, India. Patients undergoing dialysis on outpatient basis and patients who were admitted under the care of or referred to the nephrologists for renal dysfunction from other specialties were reviewed. Patterns of the MRPs were identified using an adapted Hepler and Strand criteria. The potential clinical significance of the MRPs and the contribution of the clinical pharmacist in resolving or minimizing some of the MRPs were also explored. RESULTS AND DISCUSSION: Three hundred and twenty-seven MRPs were identified with 308 patients reviewed. The incidence of MRPs was found to be 1·06 ± 0·85 per patient reviewed. The most common MRP identified in our study was overdose (19·3%) followed by adverse drug reactions (19·0%). Cardiovascular agents (33·6%) followed by anti-infective agents (26·3%) were the most common therapeutic classes of medication implicated in causing MRPs. Twenty-six per cent of the MRPs identified were explored to be potentially moderate or major in clinical significance. The clinical pharmacists' recommendations were accepted in 97% of the cases, which resulted in a change in therapy in 83% of the cases. WHAT IS NEW AND CONCLUSION: Medication-related problems are frequent in renally compromised patients in our patient population. The high level of acceptance of clinical pharmacist's recommendations by the nephrologists demonstrates that clinical pharmacists may help improve overall patient care in this setting.

An assessment of the quality of life in hemodialysis patients using the WHOQOL-BREF questionnaire.

A cross-sectional study was conducted to evaluate the quality of life (QOL) of hemodialysis patients. An attempt was made to compare the QOL of hemodialysis patients with the QOL of the general population, renal transplant patients, and patients with a chronic disease, in this case, asthma. The WHOQOL-BREF questionnaire was used to assess the quality of life. Hemodialysis patients who had completed three months of maintenance hemodialysis (n = 75) were enrolled into the study. The quality of life of hemodialysis patients was found to be significantly impaired (P < 0.05) in comparison to healthy individuals of the general population, particularly with respect to the physical, psychological, and social relationship domains. In comparison to the quality of life of renal transplant patients, the quality of life of hemodialysis patients was significantly (P < 0.05) lower in all the four WHOQOL-BREF domains. Only in the environmental dimension was the quality of life of hemodialysis patients found to be significantly lower than that of the asthma patients. Female hemodialysis patients showed significantly (P < 0.05) lower quality of life than did male patients in the psychological and environmental dimensions of WHOQOL-BREF. A positive association was seen between higher education and the psychological functioning and the environmental dimensions of WHOQOL-BREF. Thus, the quality of life of hemodialysis patients was found to be considerably impaired when compared to that of healthy individuals of the general population as well as of renal transplant patients.
