Potentially inappropriate medications prescribed for older persons: A study from two teaching hospitals in Southern India.

BACKGROUND: Potentially inappropriate medications (PIMs) are a major concern in geriatric care. The primary objective of our study was to assess the prevalence of PIMs prescribed for older persons attending outpatient setting of two teaching hospitals in Kerala state in South India, where the population is aging. MATERIALS AND METHODS: A cross-sectional study was carried out in two teaching hospitals in Kerala. Four hundred consecutive outpatient medical records of patients aged 65 years and above were selected. The current medications of the patients were analyzed to identify PIMs by the Beers criteria 2015. Polypharmacy and hyperpolypharmacy were defined as 5-9 medications and ≥10 medications, respectively. Chi-square test was done to identify demographic variables and the pattern of health-care facility use associated with PIM prescription. Binary logistic regression was performed to adjust for confounding associations. RESULTS: The prevalence of PIMs prescription was 34.0% (95% confidence interval: 29.4%-38.6%) and that of polypharmacy and hyperpolypharmacy was 45.8% and 13.5%, respectively. The common PIMs were proton-pump inhibitors, benzodiazepines, peripheral α-1 blockers, and first-generation antihistamines. Inpatient admission, visits to the emergency department, multiple diagnoses, polypharmacy, and hyperpolypharmacy were associated with PIM prescription (P < 0.05). Age, gender, number of outpatient visits, and specialist consultation were not associated with PIM prescription. Polypharmacy (adjusted odds ratio [aOR] =2.11) and hyperpolypharmacy (aOR = 5.55) had independent association with PIM prescription (P < 0.05). CONCLUSION: PIM prescription appears to be common in teaching hospitals in Kerala. Polypharmacy and hyperpolypharmacy in older people should trigger a review of medication to reduce the use of PIM.

Hepatitis and thrombocytopenia: markers of dengue mortality.

Dengue fever is of great concern to public health in India as it contributes significantly to the burden of healthcare. The aim of our study was to measure mortality in dengue and its association with hepatitis and thrombocytopenia. Our study was performed in a tertiary care setting in the state of Kerala in southern India. Adult patients admitted in the year 2013 were included. Among 1308 confirmed dengue patients, the mortality rate was 1.76%. Hepatitis and thrombocytopenia were present in over 80% of all patients, but severe hepatitis was seen in 11.4% and severe thrombocytopenia in 9.3%. These were markers of fatal outcome. Other factors significantly associated with mortality were age >60 years, male sex, diabetes and the presence of any co-morbidity.

Immune thrombocytopenia with multi-organ dysfunction syndrome as a rare presentation of scrub typhus: a case report.

BACKGROUND: Scrub typhus is an acute infectious illness caused by Orientia tsutsugamushi. It is endemic to a part of the world known as the "tsutsugamushi triangle". Humans are accidental hosts in this zoonotic disease. About a third of patients admitted with scrub typhus have evidence of multi-organ dysfunction. Multi-organ dysfunction secondary to scrub typhus carries a high mortality rate. CASE PRESENTATION: We report a 65-year old lady who was admitted in a Tertiary Care Center in the state of Kerala in India, with 7 day history of fever, myalgia and reduced urine output. Head to foot examination revealed the presence of an eschar on her chest. One week prior to the onset of her illness she had gone trekking through a hilly forest area. She was clinically suspected to have scrub typhus, which was later confirmed with laboratory tests. She developed multi-organ dysfunction syndrome secondary to this illness. Though there was an improvement in the multi-organ dysfunction, thrombocytopenia alone failed to improve. Bone marrow study was done which was suggestive of immune thrombocytopenia. Patient was given a course of steroids with which the thrombocytopenia improved. CONCLUSION: Failure of platelet count to normalize even after there has been a general improvement of other markers of multi-organ dysfunction in scrub typhus should prompt the clinician to consider other potential causes of thrombocytopenia. An unusual finding as this calls for further research to understand the molecular mechanisms behind such an event. Further, considering the close similarity in clinical presentation of several tropical illnesses, meticulous history taking and a detailed physical examination needs to be emphasized.

Predictors of outcome in patients admitted with acute exacerbation of chronic obstructive pulmonary disease in a rural Tertiary Care Center.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is associated with a high degree of mortality and morbidity around the world with the burden of the disease being more in the developing countries. In the Indian context data is limited. This study was carried out to determine the predictors of outcome in patients admitted with acute exacerbation of COPD in a rural Tertiary Care Center in the state of Kerala. MATERIALS AND METHODS: This was a prospective cohort study. Patients admitted with acute exacerbation of COPD in the Intensive Care Unit between August 2013 and July 2014 was included in the study. Sociodemographic data, clinical variables, and investigations were collected. Mortality with respect to relevant risk factors was compared using Kaplan-Meier method and Cox proportional hazard model. RESULTS: Seventy patients were enrolled in the study of whom 58 (82.9%) were above the age of 60 years. Majority of the patients (87.1%) were males. Tobacco smoking was the main risk factor in them. All the females had a history of exposure to biomass fuel in the form of firewood; none of them were smokers. Majority of patients (80.0%) had a history of one or more co-existing illnesses. Anemia was found to be an independent risk factor for mortality (adjusted hazard ratio: 3.167, 95% confidence interval: 1.516-6.616). Risk factors for poor outcome in COPD patients reported from other centers in India were not found to be relevant in this study. CONCLUSIONS: Anemia could be an independent risk factor for mortality in COPD patients. India already has a high prevalence of iron deficiency anemia especially in the rural area and in the geriatric population. Henceforth, family practitioners and primary care physicians may remain vigilant regarding the development of anemia in their COPD patients and institute remedial measures without delay. Futhermore, the wide variation reported in the predictors of outcome of COPD along with the finding of this study calls for an urgent need for more studies.
