Analysis of Factors Associated with Thyroid Dysfunction: A Hospital Based Study

Background Thyroid dysfunction (TD) is one of the major public health concerns in Nepal. This study intends to identify factors in association with thyroid dysfunction and its hospital based prevalence. Objective To determine hospital-based prevalence of thyroid dysfunction and to identify and analyze factors in association with thyroid dysfunction. Method A retroprospective cross-sectional study was conducted among patients attending Dhulikhel Hospital-Kathmandu University Hospital (DH,KUH) from January to December, 2015 with prospective part carried out from July to December 2015 in the patients visiting Dhulikhel hospital for health check-up and requested for Thyroid Function Tests (TFTs). Thyroid Function Tests of 1530 subjects were performed in the biochemistry laboratory and semi-structured questionnaire were introduced to 312 participants with convenient sampling method and their anthropometric measurements were taken. Chi-square test, Pearson's correlation and student-t test were used as a measure to analyze factors. Result Out of total 1530 subjects, 35.3% were having thyroid dysfunction with the prevalence of overt hyperthyroidism, subclinical hyperthyroidism, overt hypothyroidism and subclinical hypothyroidism to be 2.5%, 2.4%, 5.6% and 24.8% respectively. The distribution of thyroid dysfunction was preponderant among females and among older age. The prevalence of thyroid dysfunction was highest among Terai/Madhesi (40.0%) and lowest among Newars (28.5%) with higher fraction of hypothyroidism in each ethnic group. There were significant correlation between Thyroid Stimulating Hormone (TSH) with waist-hip ratio (p<0.05) and weight (kg) with free thyroxine (fT4) (p<0.05). Direct pesticide exposure (p<0.05) was significantly associated with hypothyroidism. The serum fT4 was significantly different (p<0.05) among vegetarian and non-vegetarian whereas TSH and free triiodothyronine (fT3) were not significantly different. Smoking, alcoholism, dietary food habits, diabetes and hypertension were not significantly associated with thyroid dysfunction. Conclusion Thyroid dysfunction was highly prevalent among participants with higher proportion of subclinical hypothyroidism. Besides, direct pesticide exposure found to be factor in association with hypothyroidism, this study could not find significance relation with other established risk factors.

Reasons for Summoning Ambulance Services in the Hilly Region of Nepal

Background Nepal lacks a unified and countrywide emergency medical services system as other developing countries. However, the emergence of ambulance service initiatives in the past decade shows a promising future for pre-hospital care. Nepal Ambulance Service (Est. 2011) and Dhulikhel Emergency Medical Services (Est. 2013) are the existing emergency medical services initiatives in Nepal. Objective To describe the reason for summoning ambulance services and demographics of the patients who were transported by Dhulikhel Emergency Medical Services at Dhulikhel hospital, hilly region of Nepal. Method One thousand three hundred and ninety three patient records at Dhulikhel hospital transported by Dhulikhel Emergency Medical Services during the five-year period (2013 - 2018) were included in the study. Chief complaints and demographic data were collected and categorized into overarching systemic categories. Result Among 1393 patients, majority were female (60.4%) and the most common age group was 20-29 years. The most common reason for calling ambulances was gastrointestinal problem (22.6%). Similarly, respiratory (17%), obstetric and gynecological (15.2%), trauma (12.7%) and neurological (9.6%) problems were other common reasons. The number of respiratory problem was increased during the winter season. The overall percentage of patients arriving at hospital with trauma problems was increased steadily, but it was not statistically significant. Conclusion Gastrointestinal problem was the most common reason, followed by respiratory and obstetric and gynecological problems for summoning ambulances services in the hilly regions of Nepal. The incidence of respiratory problem significantly increased during the winter season.

Profile of Obstetric and Iatrogenic Fistula Surgeries At Kathmandu Model Hospital

Aims: To find out the pattern of urogenital fistula. Methods: This was a retrospective study of 222 patients who underwent fistula surgery during the period of January 2012 to March 2018 in Kathmandu Model Hospital. The data were collected from the hospital records. The fistulae were classified according Goh system.  Patients’ demography, obstetric characteristics and surgical outcome were reviewed. The primary outcome was in terms of urinary continence. Results: Among 222 cases, majority of the patients had fistula due to obstetrical cause, contributing 58% (n=127) and 42% (n=95) had fistula after gyanaecological surgery. The age ranged from 15 to 65 years. Most of the patients had fistula of type 1a, contributing 38% (n=84) and only 0.01% (n=3) of type 3c and 4b according to Goh’s classification. Hundred (78.7%) cases of obstetric fistula patients were dry and continent after surgery, whereas 95(89.4%) cases of fistula after gynecological surgery were successfully repaired. Eighteen patients with obstetric fistula and 6 patients with fistula after gynecological surgery had failed repair. Conclusions: Our study showed obstructed and prolonged labor was the major cause of obstetric fistula, but   fistula resulting after gynecological surgery should not be overlooked.

A micro-pipette thermal sensing technique for measuring the thermal conductivity of non-volatile fluids

This research work demonstrates an innovative technique to measure the thermal conductivity of a small volume of non-volatile liquids. The method utilizes a micro-pipette thermal sensor (MPTS) (tip diameter < 2 μm) and is based on laser point heating thermometry and transient heat transfer. A laser beam is irradiated at the sensor tip immersed in a few microliters of the test fluid and the transient temperature change is recorded with the sensor. This temperature change is dependent on the surrounding fluid's thermal properties, such as thermal conductivity and diffusivity. The numerical solution for transient temperature profile for a point source is obtained using the finite element method in the COMSOL software. To determine the optimizing parameters such as thermal conductivity and power absorbed at the sensor tip, the multi-parameter fitting technique is used in MATLAB, which will fit the COMSOL simulation result with the experimental data. Three liquids with known thermal conductivity were tested to verify that the technique can be used to determine the thermal conductivity with high accuracy, and in addition, the thermal conductivity of growth media and serum used for culturing cancer cells is estimated. With the sensor size of 1-2 μm, we demonstrate the possibility of using this described method as the MPTS technique for measuring the thermal properties of microfluidic samples and biological fluids.

Deep Brain Stimulation in Parkinsons Disease in Nepal

Background Parkinsons disease is a central nervous system degenerative disorder affecting motor system and characterized by progressive tremor, rigidity, gait abnormalities. Surgical treatment of Parkinsons disease is based on the changes in the basal gangliothalamocortical circuits which is altered in Parkinsons disease. Currently pallidotomy and Deep Brain Stimulation are available modes of surgical treatment of Parkinsons disease. Objective To know efficacy of deep brain stimulation in Parkinsons Disease in Nepal. Method All patients of idiopathic Parkinsons disease who underwent Deep Brain Stimulation in Annapurna Neurological Institute and Allied sciences since 2014 were included. The standard functional coordinates for Subthalamic nucleus and Globus pallidus internus was used. We used Zamarano-Dujovny (ZD) Fisher Frame with its software. Patients' Unified Parkinsons disease rating score, Modified Hoehn and Yahr Staging and Schwab and England Activities of daily living Scale were evaluated preoperativelyv as well as postoperatively. Result Ten patients underwent Deep Brain Stimulation. The male is to female ratio was 2:1. The mean age was 55.4±8.9 years and duration of illness was 5.5±2 years. There was a significant improvement in the scores for the main motor manifestations of the disease between the preoperative off-dopa and postoperative off-dopa/on-stim conditions. There was a significant improvement in Schwab and England Activities of daily living scale scores in the off-dopa condition between the preoperative score and the postoperative M6 score. Conclusion Our result of Deep Brain Stimulation is quite promising. However, it is very expensive and requires frequent follow-up for neuromodulation.

Medication Adherence to Levothyroxine Therapy among Hypothyroid Patients and their Clinical Outcomes with Special Reference to Thyroid Function Parameters

Background Non-adherence to medication in hypothyroid patients leads to poor clinical outcome and increased health care costs. Study related to adherence to levothyroxine in hypothyroid patients is limited worldwide. Objective To determine the adherence pattern and factors affecting adherence in hypothyroid patients and compare the clinical outcomes among adherent and non-adherent patients. Method A cross-sectional study was conducted in Dhulikhel hospital, Kathmandu University hospital. Patients with hypothyroidism on levothyroxine fulfilling the inclusion criteria were enrolled in this study. After obtaining the informed consent from the patients, structured questionnaire was used to interview the patients. Statistical analysis was performed by using SPSS 23.0. P-value < 0.05 was considered as statistically significant. Result Among 113 patients enrolled in this study, 85.8% of them were females. Majority (76.10%) of them belonged to the age group of 31-40 years. More than half (51.3%) of the patients were adherent to medication. Non-adherence was significantly associated with literate people following medication (p=0.003, OR=0.305), missed appointment to follow-up (p=0.007, OR=0.346) and longer duration of medication (p=0.019, OR=4.385). However, there was no statistically significant association of clinical outcomes with reference to TSH, fT4, fT3 and patients' age, adherence to medication and concomitant use of other drugs. Conclusion More than half of the patients were adhered to the Levothyroxine therapy. Forgetfulness was the main reason for missing the dose and non-specific reasons attributed to discontinuation of medication for these patients. Good adherence was seen among illiterate people. Treatment related factor, patient-provider relationship and patient related factor were determined as the major barrier to medication adherence. Most of the non-adherent patients had uncontrolled TSH.

Radiographic Anatomy of the Neck-Shaft Angle of Femur in Nepalese People: Correlation with its Clinical Implication

Background Neck-shaft angle (NSA) is one of the prominent features in the proximal femur which is an important determinant of fracture of femoral neck. Present study evaluating the value of neck-shaft angle has relied heavily on radiographs. As knowledge of neck-shaft angle is important to orthopaedic surgeons, there is need to elucidate whether there is significant variation of this angle among the two different genders and various age groups of both right and left femora of Nepalese population. Objective To ascertain the value of neck-shaft angle in the Nepalese population by means of a radiographic study and to correlate the values with regard to right neck-shaft angle/ left neck-shaft angle side (RNSA/LNSA), gender and three different age group. Method Normal pelvic radiographs of 148 patients seen at department of orthopedic and radiology, College of Medical Sciences- Teaching Hospital (COMS-TH), Bharatpur, Chitwan from the month of February 2017 to June 2017 were divided into two different gender and three different age groups (21-40 years, 41-60 years and Above 60 years) and their neck-shaft angle of both right and left sides were recorded. Result The average of RNSA and LNSA were found to be 132.96±6.05° and 131.54±13.66° respectively for male and 134±6.57° and 132.98±6.23° respectively for female. In total the average RNSA and LNSA were 133.51±6.32° and 132.26±10.61° respectively. Similarly, the average RNSA and LNSA for three different age groups (21-40 years, 41-60 years and Above 60 years) were found to be 133.76±6.44°, 133.69±6.36° and 132.50±6.06° and the 133.35±6.29°, 132.47±5.85° and 128.84±21.98° respectively. Conclusion The average neck-shaft angle recorded here shows no significant difference in both RNSA and LNSA in males except for a small and significant difference in LNSA in female of three different age groups.

Clinical Outcome following Intra-articular Triamcinolone Injection in Osteoarthritic Knee at the Community: A Randomized Double Blind Placebo Controlled Trial

Background Knee pain is one of the common complaints patients present with in any community based health camps and Osteoarthritis of knee is a usual diagnosis. Injecting a long acting steroid is a common practice to alleviate the symptoms of osteoarthritic knee. Objective To evaluate the clinical outcome of injecting Triamcinolone acetenoid in osteoarthritis of knee in a community set up over a randomized double-blind placebo control trial. Method A prospective, randomized, double blind, placebo control trial was carried out in community after obtaining the ethical clearance from the IRC. Patients with clinically diagnosed osteoarthritis of knee were injected either Triamcinolone or Placebo after recording the baseline scores of the knee by Knee injury and Osteoarthritis Outcome Score (KOOS) - Physical Function Short form (KOOS-PS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Visual Analogue Scale (VAS). The same tools were used at two, six and at twelve weeks post injection to evaluate the functional outcome and pain. Result One hundred and seventeen patients were available for analysis among which, 55(48.7%) patients received Triamcinolone and 58(51.3%) received placebo. The baseline status of knees of two groups was comparable at the start of study. There was significant pain relief in the group receiving Triamcinolone at two and six week but not in twelve weeks. Group receiving placebo had pain relief only for first two weeks. Functional outcome was significantly improved compared to baseline in both the groups until six weeks however, in the triamcinolone group, it was significant until twelve weeks. No major complications were noted. Conclusion Intra-articular injection of Triamcinolone acetenoid is effective in symptoms control and improving functional outcome in clinically diagnosed osteoarthritis of knees in community set up during health camps.

Experience of Laparoscopic Gynecological Surgeries at Kathmandu Model Hospital

Aims: Laparoscopy has become the most common procedure in recent set-ups. It is now a major diagnostic as well as therapeutic modality for infertility, endometriosis, extrauterine pregnancy and benign ovarian tumors. The aim of the study was to share the experience of gynecological laparoscopic surgeries performed at Kathmandu Model Hospital. Methods: A descriptive study was carried out at Kathmandu Model Hospital from 1st January 2011 to 1st May 2017. All the patients who underwent gynecological laparoscopic surgeries were analyzed for the indication, type of procedure and its complications. Results: Out of 217, majority 24.4 %(n=53) patients were in age group 26-30 years. There were 51.1% (111) cases of ovarian cyst, 12.44%(27) cases of ectopic pregnancy. Eight cases were done with surgeons for cholecystectomy and ovarian cystectomy or hysterectomy. There were 15% (n=32) cases of diagnostic laparoscopy. Total laparoscopic hysterectomy was done in 16% (n=33) cases. Conversion to laparotomy was done in 3%(8) cases. There was one case of vascular injury. Most common immediate post-operative complaint was variable degree of pain, managed with parenteral and oral analgesics. Oral diet started at 4-6th hour post-operatively, and mobilization started after 24 hours. 75% (164) cases had a hospital stay of 2 days and 25%(53) cases stayed for 3 days. Conclusions: Laparoscopic surgery at our hospital has been well demonstrated in terms of reducing postoperative pain and decreasing postoperative morbidity, short hospital stay, and less postoperative recovery time. However, adequate advanced training and devices are needed to perform skillful laparoscopic surgeries. 

Outcome Analysis of Neonates following Laparotomy for Acute Abdomen: A Prospective Study

Background Low and middle-income countries (LMIC) bear the majority of the global pediatric surgical burden. Despite increasing volume of pediatric surgeries being performed in LMIC, outcomes of these surgeries in low and middle-income countries remain unknown due to lack of robust data. Objective The objective of our study was to collect data on and evaluate neonatal surgical outcomes at a tertiary level center in India. Method The surgical outcomes data of all neonates undergoing laparotomy between February 15, 2015 and October 14, 2015, at Sir Ganga Ram Hospital, New Delhi, India was collected prospectively. Descriptive statistics were used to determine the rates of various postoperative outcomes. Result A total of 37 neonatal surgeries were performed during the study period. The mean age of the neonates on the day of surgery was 7 days (range: 1-30 days). Most of the neonates (72.9%, n=27) were males. About 40% (n=15) of the neonates were preterm and 15 (40.5%) of them were small for gestational age. In our study, 10 neonates (28.6%) needed ventilation for 48 hours or less after surgery and 5 neonates (13.5%) were kept Nil per Oral (NPO) postoperatively for more than 10 days. Out of 37 neonates, 4 (10.80%) developed a surgical site infection and 8 neonates (21.6%) had postoperative sepsis. The in-hospital mortality rate among neonates undergoing laparotomy during the study period was 8.1 deaths per 100 neonates. Conclusion Co-ordination of care among pediatric surgeons, neonatologists, nursing and anesthesia team is required for optimal surgical outcome.

Improving Knowledge, Skill and Confidence of Novice Medical Doctors in Trauma Management with Principles of ABCDE

Background Trauma is one of the major public health concerns clamming about five million death annually worldwide. Experience and confidence of a doctor in the management of trauma patients have big impact on the overall outcome. Objective This study aims to evaluate the outcome of a trauma course in improving the knowledge, skill and confidence of novice doctors in managing trauma victims. Method A pre/post test analytical study was carried out among novice medical doctors from Kathmandu University School of Medical Science (KUSMS) who participated in a standard two and a half day trauma course, that utilizes the principles of ABCDE, as a part of their regular training. Pre-course knowledge and skill were compared with immediate post-course scores on the same guidelines. Objective structured and subjective written feedbacks from the participants were analyzed qualitatively to identify the perceptions of candidates. Result Sixty-eight males and twenty-nine females completed the course. The average pre-test scores in knowledge and skill were 8.3(33.2%) and 19.6(78.5%) respectively. Similarly the post-test scores were 16.04(64.2%) and 22.45 (89.5%) respectively, showing statistically significant improvements (P 0.000). The mean percentage improvement in knowledge was 48.8% and that in skill was 160.9%. The feedback analysis showed majority of the participants were satisfied with the course and they perceived improved "self-confident" in handling trauma cases. Conclusion All the novice doctors should participate in a standard trauma course hence their knowledge, skill and confidence in handling a trauma can be improved.

Monopolar cautery was used for laparoscopic colpotomy and vault was closed by laparoscopic single running suture, that is, one-minute laparoscopic vault closure technique. Patients were followed up for vaginal cuff dehiscence and the dehiscence rate was compared with other techniques of laparoscopic vault closure in laparoscopic hysterectomy.Results: This study showed that the rate of vaginal cuff dehiscence after one minute technique of laparoscopic vault closure in laparoscopic hysterectomy was 1/1012 patients (0.09%) which was significantly less as compared to other techniques of laparoscopic vault closure in laparoscopic hysterectomy quoted in the literature.Conclusions: One minute technique of laparoscopic vault closure after colpotomy with monopolar cautery using single running suture has encouraging results. It is a noble technique of laparoscopic vault closure with excellent support. It can be practiced in low resource setting also.

Acute Upper Gastrointestinal Bleeding in a Tertiary Care Centre of Nepal

INTRODUCTION

AUGIB is characterized by hematemesis or melena or both. Peptic ulcers and variceal bleed account for majority of cases. Use of proton pump inhibitors in current era is associated with a gradual reduction in burden of peptic ulcer disease. We conducted this study to look into the cause of AUGIB in our community.

METHODS

We studied 100 patients in one year period who presented to us with hematemesis or melena. The study was conducted in department of Gastroenterology, Bir hospital, Kathmandu. We identified the culprit lesions by upper gastrointestinal endoscopy.

RESULTS

The average age of patients with AUGIB was 51.6 years with 59 (59%) males. Duodenal ulcers are most common 29 (29%), followed by varices 23 (23%) and gastric ulcers 14 (14%). More than one lesion was identified in 38 (38%) patients. Patients with variceal bleed were more likely to present with hematemesis alone as compared to those with ulcer bleed (P=0.005). Variceal bleed patients presented earlier to the hospital (P=0.005), had lower MAP at presentation (P=0.0002), had lower hemoglobin level (P=0.0001) and higher serum creatinine level at presentation (P=0.001). Patients with variceal bleed were more likely to have consumed alcohol 20 (86.9%) and patients with ulcer bleed were more likely to be smokers 29 (67.4%) or consume tobacco 14 (32.5%) (P=0.006).

CONCLUSIONS

Ulcer related bleeding is still the most common cause of AUGIB. Many patients with AUGIB have more than one lesions identified during upper gastrointestinal endoscopy.

Approximation of Height of an Individual Using Somatometry of Human Male Skull

INTRODUCTION

Numerous population specific studies conducted on skeletal remains have aimed to standardize the identification process. Known for ethnic and sexual variations, skull bone can also assist the identification process by estimating stature of the individual. The present study focuses on estimation of stature from skull bone using uni-variate and multi-variate regression models in south Indian population.

METHODS

Stature and maximum cranial length, maximum cranial breadth, bi-pterion breadth, parietal cord and upper facial breadth were measured in wet skulls of 113 males, autopsied at Government Hospital of Kudla, Karnataka.

RESULTS

All five measurements showed significant correlation with stature (P value <0.001). MCL showed the highest (r=0.77) and UFB the lowest (r=0.42) degree of correlation. Standard error of estimate was lowest for MCL (4.90 cm) in the derived uni-variate regression models. In the regression model obtained from the multi-variate analysis using all five skull measurements the β-coefficients were significant (P value <0.001) and the Standard Error of Estimation of the model was observed to be 4.45 cm. Bland-Altman analysis was conducted to explore the agreement between the actual length and the estimated lengths from the multivariate regression model. The mean of difference was 0.105 with a standard deviation of 4.3 and the upper and lower limits of agreement were 8.5 and -8.3 respectively.

CONCLUSIONS

The study concludes that stature can be estimated from skull measurements with reasonable accuracy, observations of multi-variate regression models being more precise than the uni-variate regression models. Data collected from South India was compared with data available for Nepalese population and validates the use of data of Indian population for extrapolation in Nepalese population.

Displaced Intra-Articular Calcaneal Fractures: Evaluation of Clinical and Radiological Outcome Following Open Reduction and Internal Fixation with Locking Branched Calcaneal Plate

Background Calcaneal fractures are common, but are difficult to manage. Immediate concern is soft tissue problems, while long term concern is pain as a sequelae of subtalar arthritis. A consensus has not been reached in the management of calcaneal fractures. Objective This study aims to evaluate clinical and radiological outcomes of the patients managed with open reduction and internal fixation with Calcaneal Locking Plates for the displaced intra-articular calcaneal fractures presenting in Dhulikhel Hospital, Kathmandu University Hospital. Method This was a prospective study, conducted on displaced intra articular calcaneal fractures from January 2014 through December 2016. The patients underwent open reduction and internal fixation with Locking Branched Calcaneal Plates through the extensile lateral approach. Post-operatively, ankle was mobilized after two weeks. Weight bearing was started after 12 weeks. Patients were evaluated clinically with Maryland foot score and radiologically with measurements of Boehler's and Gissane angle. Result Twenty-two cases of calcaneal fractures managed with open reduction and internal fixation with Locking Branched Calcaneal Plates were available for final evaluation. Seventeen of the enrolled patients were males in their third decade of life. On average, calcaneal fractures were operated on seven days after the injury. Sanders Type II were seen in 68.2% of the cases and Sanders Type III were in 31.8%. Mean follow-up duration was 21.5 months. The average Maryland foot score was 77.27. Seventeen cases (77.13%) had good, four cases (18.2%) had fair, and one case (5.5%) had poor outcome score. There was statistically significant improvement in Boehler's and Gissane angle across all enrolled patients. Conclusion Displaced intra-articular calcaneal fractures treated operatively with open reduction and internal fixation with Locking Branched Calcaneal Plates through the extended lateral approach, with proper planning of operation and surgical techniques in soft tissue handling, results in good clinical as well as radiological outcomes.

Fluoroscopy Guided Percutaneous Transpedicular Biopsy for Thoracic and Lumbar Vertebral Body Lesion: Technique and Safety in 23 Consecutive Cases

Background Though some vertebral lesions have typical imaging findings, histological/ microbiological evidence are required for definitive diagnosis and management, specially for tumor and infective lesions so that wrong diagnosis and wrong treatment can be avoided. Conventionally, open biopsy methods are used. With availability of CT scan, MRI, percutaneous transpedicular vertebral biopsy has now become popular as a minimally invasive technique for biopsy of vertebral lesion.Objective To describes technique and to analyzes safety and feasibility of percutaneous transpedicular vertebral biopsy with fluoroscopy guidance for thoracic and lumbar vertebral body lesions.Method Twenty three patients who underwent percutaneous transpedicular vertebral biopsy under fluoroscopy guidance were retrospectively evaluated for demographic data, indication for biopsy, anatomical locations, histological/microbiological diagnosis, complications and final outcome of treatment. True positive, true negative, false positive and false negative cases were defined.Result There were 17 males and 6 female patients of mean age 47 (range 22-73 years). Biopsies were performed in 17 dorsal and six lumbar vertebral bodies. Adequate sample were obtained in all cases. Seventeen patients (12: tubercular pathology, 1: primary tumor, 3: metastasis, 1: osteoporotic fracture) had definitive histological/ microbiological diagnosis. Four patients had no granuloma and tumor. Two had histological features of chronic non specific inflammation. True positive cases were 17, true negative were four and false negative case were two. Overall accuracy was 92%. One patient developed small hematoma at biopsy site.Conclusion Fluoroscopy guided percutaneous transpedicular biopsy of is a safe procedure with high adequacy and accuracy and low complication rate for thoracic and lumbar vertebral body lesion.

Study of Pre-disposing Factors of Acute Exacerbation of Chronic Obstructive Pulmonary Disease and Antibiotic Prescribing Pattern with Reference to Antibiotic Sensitivity Test

Background Chronic Obstructive Pulmonary Disease (COPD) affects about 329 million people worldwide, which is nearly 5% of the entire global population. In the context of Nepal, COPD accounts for 43% of the non-communicable disease burden and 2.56% of hospitalizations. Various pre-disposing factors like bacterial, viral, fungal, smoking, occupational exposures and genetic factors have been proposed to precipitate COPD and its exacerbation though, the definitive pre-disposing factors and factors related to acute exacerbation have not been determined in the context of Nepal.Objective To find out the pre-disposing factors and the related causative agents for COPD.Method A cross sectional study was conducted in a tertiary care hospital. Patients of all age group who were diagnosed as COPD and admitted in the hospital were included in this study. Patients were interviewed using structured questionnaire. The socio-demographic data including personal and medical history were recorded from those participants. In addition, sputum from those patients was sent for culture to investigate the possible responsible pathogens as well as its antibiotic sensitivity pattern.Result A total of 150 patients having Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) who have admitted from either emergency or out-patient department of the hospital were included in this study. Among the total number of patients, more than half of them were female (n=82). In addition, analysis of occupations shows that most of them were either farmer (36.0%) or housewife (30.7%). In total studied patients (n=150), most of them were using traditional firewood (83%) for cooking purpose and majority of patients (91%) were smokers. Most of the sputum samples show growth of gram-positive cocci (26.7%) and gram negative bacilli (27.5%). Considering the overall sensitivity pattern, the higher sensitivity was recorded for Co-trimoxazole and Ciprofloxacin while higher rate of resistance was noted for Penicillin group of drugs. The most widely used antibiotics were found to be Cephalosporin group of drugs (68%).Conclusion The present study revealed that the case of COPD is more in female and the commonest pre-disposing factor is found to be smoke/firewood. Cephalosporin group of drugs is the most commonly prescribed drug.
