Development and validation of a clinical and computerised Decision Support System for Management of Hypertension (DSS-HTN) at a Primary Health Care (PHC) setting

Background: Hypertension remains the top global cause of disease burden. Decision support systems (DSS) could provide an adequate and cost-effective m

The timing of death in patients with tuberculosis who die during anti-tuberculosis treatment in Andhra Pradesh, South India

Background: India has 2.0 million estimated tuberculosis (TB) cases per annum with an estimated 280,000 TBrelated deaths per year. Understanding when in the course of TB treatment patients die is important for determining the type of intervention to be offered and crucially when this intervention should be given. The objectives of the current study were to determine in a large cohort of TB patients in India:- i) treatment outcomes including the number who died while on treatment, ii) the month of death and iii) characteristics associated with “early” death, occurring in the initial 8 weeks of treatment. Methods: This was a retrospective study in 16 selected Designated Microscopy Centres (DMCs) in Hyderabad, Krishna and Adilabad districts of Andhra Pradesh, South India. A review was performed of treatment cards and medical records of all TB patients (adults and children) registered and placed on standardized anti-tuberculosis treatment from January 2005 to September 2009. Results: There were 8,240 TB patients (5183 males) of whom 492 (6%) were known to have died during treatment. Case-fatality was higher in those previously treated (12%) and lower in those with extra-pulmonary TB (2%). There was an even distribution of deaths during anti-tuberculosis treatment, with 28% of all patients dying in the first 8 weeks of treatment. Increasing age and new as compared to recurrent TB disease were significantly associated with “early death”. Conclusion: In this large cohort of TB patients, deaths occurred with an even frequency throughout anti-TB treatment. Reasons may relate to i) the treatment of the disease itself, raising concerns about drug adherence, quality of anti-tuberculosis drugs or the presence of undetected drug resistance and ii) co-morbidities, such as HIV/ AIDS and diabetes mellitus, which are known to influence mortality. More research in this area from prospective and retrospective studies is needed

Hypertension in India: A systematic review and meta-analysis of prevalence, awareness, and control of hypertension

Background: A region-specific (urban and rural parts of north, east, west, and south India) systematic review and meta-analysis of the prevalence, awareness, and control of hypertension among Indian patients have not been done before. Methods: Medline, Web of Science, and Scopus databases from 1950 to 30 April 2013 were searched for 'prevalence, burden, awareness, and control of blood pressure (BP) or hypertension (140 SBP and or 90 DBP) among Indian adults' (18 years). Of the total 3047 articles, 142 were included. Results: Overall prevalence for hypertension in India was 29.8% (95% confidence interval: 26.7-33.0). Significant differences in hypertension prevalence were noted between rural and urban parts [27.6% (23.2-32.0) and 33.8% (29.7-37.8); P=0.05]. Regional estimates for the prevalence of hypertension were as follows: 14.5% (13.3-15.7), 31.7% (30.2-33.3), 18.1% (16.9-19.2), and 21.1% (20.1-22.0) for rural north, east, west, and south India; and 28.8% (26.9-30.8), 34.5% (32.6-36.5), 35.8% (35.2-36.5), and 31.8% (30.4-33.1) for urban north, east, west, and south India, respectively. Overall estimates for the prevalence of awareness, treatment, and control of BP were 25.3% (21.4-29.3), 25.1% (17.0-33.1), and 10.7% (6.5-15.0) for rural Indians; and 42.0% (35.2-48.9), 37.6% (24.0-51.2), and 20.2% (11.6-28.7) for urban Indians. Conclusion: About 33% urban and 25% rural Indians are hypertensive. Of these, 25% rural and 42% urban Indians are aware of their hypertensive status. Only 25% rural and 38% of urban Indians are being treated for hypertension. One-tenth of rural and one-fifth of urban Indian hypertensive population have their BP under control

Eye care infrastructure and human resources for managing diabetic retinopathy in India: The India 11-city 9-state study.

BACKGROUND: There is a paucity of information on the availability of services for diagnosis and management of diabetic retinopathy (DR) in India. OBJECTIVES: The study was undertaken to document existing healthcare infrastructure and practice patterns for managing DR. METHODS: This cross-sectional study was conducted in 11 cities and included public and private eye care providers. Both multispecialty and stand-alone eye care facilities were included. Information was collected on the processes used in all steps of the program, from how diabetics were identified for screening through to policies about follow-up after treatment by administering a semistructured questionnaire and by using observational checklists. RESULTS: A total of 86 eye units were included (31.4% multispecialty hospitals; 68.6% stand-alone clinics). The availability of a dedicated retina unit was reported by 68.6% (59) facilities. The mean number of outpatient consultations per year was 45,909 per responding facility, with nearly half being new registrations. A mean of 631 persons with sight-threatening-DR (ST-DR) were registered per year per facility. The commonest treatment for ST-DR was laser photocoagulation. Only 58% of the facilities reported having a full-time retina specialist on their rolls. More than half the eye care facilities (47; 54.6%) reported that their ophthalmologists would like further training in retina. Half (51.6%) of the facilities stated that they needed laser or surgical equipment. About 46.5% of the hospitals had a system to track patients needing treatment or for follow-up. CONCLUSIONS: The study highlighted existing gaps in service provision at eye care facilities in India

Human resources, patient load, and infrastructure at institutions providing diabetic care in India: The India 11-city 9-state study.

BACKGROUND: There is a lack of information on the practice patterns and available human resources and services for screening for eye complications among persons with diabetes in India. OBJECTIVES: The study was undertaken to document existing health care infrastructure and practice patterns for managing diabetes and screening for eye complications. METHODS: This cross-sectional, hospital-based survey was conducted in 11 cities where public and private diabetic care providers were identified. Both multispecialty and standalone diabetic care facilities were included. A semi-structured questionnaire was administered to senior representative(s) of each institution to evaluate parameters using the World Health Organization health systems framework. RESULTS: We interviewed physicians in 73 hospitals (61.6% multispecialty hospitals; 38.4% standalone clinics). Less than a third reported having skilled personnel for direct ophthalmoscopy. About 74% had provision for glycated hemoglobin testing. Only a third had adequate vision charts. Printed protocols on management of diabetes were available only in 31.5% of the facilities. Only one in four facilities had a system for tracking diabetics. Half the facilities reported having access to records from the treating ophthalmologists. Direct observation of the services provided showed that reported figures in relation to availability of patient support services were overestimated by around 10%. Three fourths of the information sheets and half the glycemia monitoring cards contained information on the eye complications and the need for a regular eye examination. CONCLUSIONS: The study highlighted existing gaps in service provision at diabetic care centers in India

Perceptions and practices related to diabetes reported by persons with diabetes attending diabetic care clinics: The India 11-city 9-state study.

BACKGROUND: India has the second largest population of persons with diabetes and a significant proportion has poor glycemic control and inadequate awareness of management of diabetes. OBJECTIVES: Determine the level of awareness regarding management of diabetes and its complications and diabetic care practices in India. METHODS: The cross-sectional, hospital-based survey was conducted in 11 cities where public and private providers of diabetic care were identified. At each diabetic care facility, 4-6 persons with diabetes were administered a structured questionnaire in the local language. RESULTS: Two hundred and eighty-five persons with diabetes were interviewed. The mean duration since diagnosis of diabetes was 8.1 years (standard deviation ± 7.3). Half of the participants reported a family history of diabetes and 41.7% were hypertensive. Almost 62.1% stated that they received information on diabetes and its management through interpersonal channels. Family history (36.1%), increasing age (25.3%), and stress (22.8%) were the commonest causes of diabetes reported. Only 29.1% stated that they monitored their blood sugar levels at home using a glucometer. The commonest challenges reported in managing diabetes were dietary modifications (67.4%), compliance with medicines (20.5%), and cost of medicines (17.9%). Around 76.5% were aware of complications of diabetes. Kidney failure (79.8%), blindness/vision loss (79.3%), and heart attack (56.4%) were the commonest complications mentioned. Almost 67.7% of the respondents stated that they had had an eye examination earlier. CONCLUSIONS: The findings have significant implications for the organization of diabetes services in India for early detection and management of complications, including eye complications
