Application of Qualitative Methods in Health Research: An Overview

Qualitative research is type of formative research that includes specialized techniques for obtaining in-depth responses about what people think and how they feel. It is seen as the research that seeks answer to the questions in the real world. Qualitative researchers gather what they see, hear, read from people and places, from events and activities, with the purpose to learn about the community and to generate new understanding that can be used by the social world. Qualitative research have often been conducted to answer the question “why” rather than “what”. A purpose of qualitative research is the construction of new understanding. Here, we present an overview of application of qualitative methods in health research. We have discussed here the different types of qualitative methods and how we and others have used them in different settings/scenarios; sample size and sampling techniques; analysis of qualitative data; validity in qualitative research; and ethical issues

A Case Study on Settlement of Oil Storage Tank Foundations

Foundations of 8 Steel Oil storage tanks and two fire water tanks were proportioned limiting total settlement to 100 mm. The soil at the site consists of alternating layers of cohesive and cohesionless soils. Settlement estimates were based on currently available methods with suitable modifications to the situation met with. The tanks were load tested (Hydrotest) and settlements observed at nine locations along the periphery on tank shell base. These observed settlements are compared with the estimated values

Prevalence of HIV seropositivity among the patients attending tertiary care hospital at Puducherry, India

Background: HIV/AIDS has been globally increasing since its first identification and reached 36.9 million by the end of 2014. It is more prevalent in underdeveloped countries. India with about 2.1 million HIV/AIDS affected people is placed third on the table followed by South Africa and Nigeria. In the present study, we aim to report the prevalence of HIV/AIDS among the patients attending our hospital in and around Puducherry, India.Methods: A total of 18903 patients attending various departments of our hospital from November 2012 to October 2015 were included in this study. HIV screening was done by rapid card test and ELISA for the detection of antibodies against HIV.Results: Out of the total study population, 259 (1.37%) were positive for HIV/AIDS. An increasing prevalence was observed in each successive year of our study. Male (1.94%) population was predominantly affected by HIV/AIDS than the females (0.90%) and is more prevalent in the 41-50 year age group.  Conclusions: Continuous monitoring, testing and counseling for HIV/AIDS would help to keep the disease under control. Special awareness and education programs are to be conducted in areas in which an increasing prevalence of HIV/AIDS is reported

ASSESSMENT OF FOOD AND NUTRIENT INTAKE OF COMMUNITIES ACROSS THREE AGRO-BIODIVERSITY HOTSPOTS IN INDIA

Balanced and adequate nutrition is important in improving the health of the community in general and of vulnerable groups in particular. Assessment of the nutritional status of a community is important for development of implementation strategies and suitable policies. Dietary assessment indicates whether intake of macro and micro nutrient are adequate. Anthropometric measurements and comparisons of nutrient intakes with reference values are easy and non-invasive, economical and sufficiently reliable methods for the determination of nutritional status. The present study uses micro-level data drawn from 24 hours recall diet survey to calculate the mean food and nutrient intake by communities in three agro-biodiversity hotspots. The 24 hours recall diet survey was carried out among households in three study locations during June to November 2013 among the project intervention and non-intervention groups. Information on age, sex, physiological status, physical activity of the household members who took meals during the previous 24 hours was collected for computing consumption unit. The result shows that cereals are the chief source of energy in the study locations contributing 70-80% of the daily energy intake. Mean intake of green leafy vegetable are negligible in the study locations. The intake of sugar and jaggery among the intervention group of Meenangadi is 48% higher than recommended dietary intake, while in the non-intervention group it is 28% higher; and 20% higher among the nonintervention group in the Kolli Hills. The intake of vitamin A is the lowest among other nutrients across the internvention and non-intervention groups in the study locations

Dissolution Enhancement and Formulation of Rapid-Release Lornoxicam Mini-Tablets

The aim was to enhance the dissolution of lornoxicam (LOR) and to produce mini-tablets with an optimised system to provide a rapid-release multi-particulate formulation. LOR systems were prepared through co-evaporation with either polyethylene glycol 6000 or Pluronic® F-68 (PLU) and adsorption onto Neusilin® US2 alone or co-adsorption in the presence of different amounts of polysorbate 80. All systems were characterised by FT-IR, differential scanning calorimetry, X-ray diffraction, flowability and dissolution techniques. Mini-tablets were prepared using the system with the optimum dissolution profile and flowability. Tensile strengths, content uniformity and dissolution profiles of the mini-tablets were evaluated. The effects of different excipients and storage conditions on mini-tablet properties were also studied. The optimised rapid-release LOR mini-tablets were further evaluated for their in vivo pharmacokinetic profile. The co-evaporate of LOR with PLU showed significantly faster dissolution and superior flowability and was evaluated together with three directly compressible excipients (Cellactose® 80, StarLac® (STA) and Emcompress®) for mini-tablet formulation. The formulation with STA provided the optimum results in terms of tensile strength content uniformity and rapid drug release following a 3-month stability study and was selected for further in vivo evaluation. The pharmacokinetic profile indicated the potential of the mini-tablets achieving rapid release and increased absorption of LO

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised
