A Study of Effect of Knowledge, Attitude, And Practice on The Diabetic Patient with Counselling as Intervention – A Non-Randomized Community-Based Trial from Gujarat

Introduction: Lifestyle modification is key to management of diabetes. Behavioural change is key to adopt lifestyle modification. The current study was planned with objective to assess the impact of coun-selling on knowledge, attitude, and practices among patients with diabetes mellitus in rural and urban areas of Gujarat. Method: It was a non-randomized interventional study conducted in the state of Gujarat, India. Known cases of diabetes were enrolled for the study. Two equal size groups of study participants from urban and rural area were divided equally for intervention group (N=77; 28 urban +49 Rural) and control group (N=77; 28 urban +49 Rural). Regular counselling on role of diet in DM management, self-care, deaddiction, role of physical activity, and drug compliance was given by community physician for three months to 6 months. Pre and post intervention KAP score was collected and evaluated. Result: The knowledge, attitude and practice score were increased among counselling group in compar-ison to traditional treatment group in both urban and rural area. The score increased from 5.4 to 10.4 in knowledge; 3.07 to 5.07 in attitude and 5.07 to 8.92 in practice among urban participants. Similarly, the score increased from 4.14 to 7.16 in knowledge, 2.57 to 3.67 in attitude and 4.73 to 7.42 in practice among rural participants. Conclusion: With counselling the knowledge, practice and attitude of chronic patients are improving. The study recommended that counselling services should be available to all diabetes patients. It should be available to patients at their doorstep if possible as study depict

Management of bio-medical waste: awareness and practices in a district of Gujarat.

With the objective of assessing the level of awareness about the various aspects of biomedical waste and disposal practices by the medical practitioners this study was conducted. It was a cross sectional study. 30 hospitals with more than 30 beds minimum were randomly selected from Sabarkantha district, Gujarat. The doctors and auxiliary staff of those 30 hospitals were the study population. While all the doctors knew about the existence of the law related to biomedical waste but details were not known. Doctors were aware of risk of HIV and Hepatitis B and C, whereas auxiliary staff (ward boys, ayabens, sweepers) had very poor knowledge about it. There was no effective waste segregation, collection, transportation and disposal system at any hospital in the district. There is an immediate and urgent need to train and educate all doctors and the staff to adopt an effective waste management practices.

Conjunctival impression cytology for detection of early vitamin A deficiency in children.

Children presenting with recurrent infections have a high risk of developing vitamin A deficiency. Conjunctival impression cytology (CIC) was used in the present study in such children to detect subclinical deficiency and to monitor the outcome after therapy. Seventy children with history of recurrent infections, and 10 healthy children in the age group of six months to five years were included in the study. CIC was performed using millipore filter paper and stained with PAS stain. A three tier grading system was used consisting of normal, borderline abnormal and abnormal for interpretation. Vitamin A supplementation was given in children in the latter two categories. Repeat cytology showed reversal to normal in these children. Hence in children with high risk of developing vitamin A deficiency, it is suggested to do CIC for detection and monitoring it.

Long term performance of atrial leads.

Long term performance of 163 atrial leads implanted in 158 patients between July 1981 and June 1993 was evaluated. There were 122 DDD and 36 AAI units, with 125 (77%) polyurethane and 38 (23%) silicone leads. One hundred and nine (67%) unipolar and 54 (33%) bipolar leads were used. Patients were followed in the Pacemaker Clinic for 6 to 124 months (mean 50 +/- 39 months). Five patients were lost to follow up. Transient malfunction was observed in 18 cases (sensing 13, pacing 5) within the first 2 weeks. In 13 cases failure to sense subsided spontaneously and in 4 pacing malfunction could be corrected by reprogramming. Lead dislodgement occurred in 4 patients (2.5%), all within the first week. After the 1st month malfunction was uncommon. Between 1 and 12 months undersensing occurred in 4 (2.5%). In 3 cases it could be corrected by reprogramming. In the first year, reoperation was performed in 5 cases for lead related problems (3 dislodgements, 2 insulation failures). Beyond 12 months complications were as follows: failure to sense-8 (5%), failure to pace-3 (2%), insulation break -1 (0.6%). Majority of these problems could be managed by reprogramming. Reoperation was performed in 1 case with insulation break. The pacing mode had to be changed in 5 (3%) patients with dual chamber units who had loss of P wave sensing. During follow-up 98%, 98%, 96%, 95% and 83% of the leads were working satisfactorily at 1,2,3,4 and 9 years respectively. Thus atrial leads have excellent long term performance and an acceptable rate of late malfunction.

Long term performance of silicone insulated and polyurethane insulated cardiac pacing leads.

The long term performance of various pacing leads in use for at least one year is reported from one centre. Between January 1975 and December 1990, 1056 cardiac pacing leads were implanted in 881 patients (mean age 57 +/- 13 years). Eight hundred and three leads were silicone insulated (SI) and 253 leads were polyurethane insulated (PUI). Leads from different manufacturers were used (Medtronic, CPI, Telectronics). The average duration of follow up was 56.6 +/- 77 months (range 12-221 months) for SI and 47.1 +/- 24 months (range 12-99 months) for PUI leads. Overall lead failure occurred more often in the PUI group (n = 46, 18.2%) compared to SI group (n = 93, 11.3%, p < 0.025). Majority of lead failures occurred in the first 36 months after implantation. In particular, Medtronic models 6971, 6972 (urethane) and 6901 (silicone) showed higher rate of complications (25.5%, 26.3% and 44.5% respectively).

Experience with recycled cardiac pacemakers.

Twelve years experience with pacemaker re-use is reported. Between November 1979 and December 1991, forty two pacemakers were re-used in 42 patients after in-hospital reconditioning. There were 31 males and 11 females in the age range of 29 to 84 years (mean 59 +/- 13 years). In 29 patients, the pulse generator was explanted because of pocket infection and/or impending extrusion, and it was re-implanted at a new site after sterilization. In the remaining 13 patients pacemakers explanted from other patients were implanted because of economic reasons. All patients were regularly followed up in the pacemaker clinic for a mean duration of 34 +/- 35 months (range 6-126 months). There was one infection and one erosion after 12 and 27 months respectively. One of these units was resterilized and implanted without any recurrence of infection or erosion over a follow up of 12 months. There was no adverse reaction or pulse generator failure. Our experience suggests that the use of refurbished pacemakers is a safe and economically viable option.

Acute hemodynamic effects of different atrioventricular intervals in dual chamber pacemakers: is there an optimum atrioventricular delay.

Conflicting data have been reported regarding adjustment of atrioventricular (AV) interval to maximise hemodynamic performance of dual chamber pacemakers. Eleven consecutive patients with complete heart block and dual chamber pacemakers were paced at three AV intervals (150, 200, 250 msec) and free running rates (60-93 bpm, mean 73 +/- 12 bpm) with simultaneous measurements of cardiac output, atrial contribution to left ventricular filling, left ventricular ejection fraction, and peak aortic velocity and acceleration by echo-Doppler techniques to define the optimum AV delay. At all the three AV intervals tested there was no difference in cardiac output (4.7 +/- 0.96, 4.83 +/- 1.12, 4.77 +/- 1.19 litres/min respectively, p = NS), left ventricular ejection fraction (60.2 +/- 10.6%, 61.2 +/- 9.9% and 64 +/- 8.3%, p = NS), atrial contribution to left ventricular filling (0.37 +/- 0.10, 0.38 +/- 0.09, 0.36 +/- 0.16, n = 8, p = NS), peak aortic velocity (104 +/- 8, 105 +/- 12, 104 +/- 13 cm/sec, p = NS) and aortic acceleration (19.68 +/- 4.26, 20.4 +/- 5.58 and 19.0 +/- 4.54 m/sec2, p = NS). Compared to AV delay of 150 msec an increase in cardiac output of 0.5 L/minute was observed in three patients at an AV delay of 200 msec and in one patient at the AV delay of 250 msec. These data suggest that it is difficult to generalize an optimum AV delay in patients with dual chamber pacemakers. With the AV interval in the range of 150-250 msec, only a minority of patients could improve their haemodynamics at rest by adjusting this interval if the baseline cardiac function was normal.

Electrocardiographic features of atrial depolarization during pacing of right atrial appendage.

Identification of atrial capture during pacing from right atrial appendage is frequently difficult. Electrocardiograms of forty five patients implanted with AAI/DDD pacemakers (thirty unipolar, fifteen bipolar) were analysed to characterize the specific morphology of paced P waves. Compared to sinus P waves, atrial pacing resulted in atrial depolarization of lower amplitude (0.16 +/- 0.05 mv vs 0.11 +/- 0.032 mv, P less than 0.005) but increased duration (0.07 +/- 0.009 sec vs 0.08 +/- 0.017 sec, P less than 0.005). P wave morphology was similar in unipolar and bipolar pacing units. It was positive in lead I (80%), II (71.11%), III (80%) and aVF (75.55%). In lead aVL, paced P waves were usually diphasic with an initial negative deflection (35.55%). Precordial leads showed paced atrial depolarization of small amplitude and did not help in identification of atrial capture. In unipolar pacing P waves were best seen in lead III because of small pacing spike in this lead. Lead II was suitable for identification of paced P waves in bipolar pacing. Thus careful examination of standard ECG leads for paced P waves of low amplitude, prolonged duration and specific morphology can help in confirming atrial capture following pacing stimulus from right atrial appendage.
