Mentoring a medical student towards applied research in a developing country

In South Asia, the student-teacher relationship is hierarchical and authoritarian. I and my colleagues spend time and energy teaching students to think, to question and to critically evaluate statements and assumptions. Bishnu Giri was an enthusiastic student willing to think out of the box. Bishnu has been involved in drug utilization studies, investigating factors influencing drug use and in promoting rational use of drugs. He has published a number of articles and has been encouraging other students to participate in research.

Fluoroquinolone utilization among inpatients in a teaching hospital in western Nepal

OBJECTIVE

To obtain information on the prescribing patterns of fluoroquinolones among hospitalized patients, other antibiotics and drugs co-prescribed, calculate fluoroquinolone utilization using defined daily dose (DDD), calculate mean cost of drugs and detail the sensitivity patterns of isolated microorganisms.

METHODS

The study was carried out over a five-month period (1st November 2003 to 31st March 2004) at the Manipal Teaching Hospital, Pokhara, Nepal. Demographic details and duration of hospitalization was noted. The percentage of patients prescribed parenteral antibiotics and fluoroquinolones were recorded. The cost of drugs was determined using the price list supplied by the pharmacy. Fluoroquinolone utilization was measured in DDD/100 bed-days.

RESULTS

Fluoroquinolones were prescribed to 263 patients during the study period; 160 females and 103 males. Mean +/- SD number of drugs prescribed and duration of hospitalization were 6.5 +/- 3.3 and 6.2 +/- 5.4 days respectively. Fluoroquinolone utilization was 7.76 DDD/100 bed-days. Ciprofloxacin was the most commonly prescribed drug (6.83 DDD/100 bed-days). Fluoroquinolones were used for prophylaxis in 110 patients (41.8%). Other indications were urinary tract infections and acute gastroenteritis. E.coli, S.aureus and P. aeruginosa were common organisms isolated. The mean cost of drugs was 13.1 U.S. $ and fluoroquinolones contributed to 36.7% of the total drug costs.

CONCLUSION

The use of fluoroquinolones was high compared to that reported previously.

Prescribing patterns in the orthopaedics outpatient department in a teaching hospital in Pokhara, western Nepal

OBJECTIVES

Information on the utilization patterns of drugs in the orthopaedics outpatient department (OPD) are lacking in hospitals in western Nepal. The present study was carried out to obtain demographic information about the respondents selected for analysis, information on the average number of drugs prescribed and the average cost of drugs per prescription. The prescriptions were critically analyzed using predetermined criteria.

MATERIALS AND METHODS

The study was carried out over a four-month period (01.09.2002 to 31.12.2002) at the Manipal Teaching hospital, Pokhara, Nepal. The percentage of encounters with an injection or an antibiotic prescribed was noted. The percentage of drugs prescribed from the Essential drug list of Nepal and the mean cost of drugs per prescription was calculated.

RESULTS

1238 patients attended the orthopaedics OPD during the study period. 186 prescriptions were randomly selected for analysis. The mean number of drugs per prescription was 1.9. Low backache was the most common reason for attending the OPD. Nonsteroidal anti-inflammatory drugs (NSAIDs) were the most commonly prescribed drug group. Diclofenac and meloxicam were the most commonly prescribed drugs. Mean cost of drugs was 166.2 Nepalese rupees. Injections and antibiotics were prescribed in 16 (8.6%) and 7 (3.8%) encounters respectively. 51 prescriptions (27.4%) had various problems. Absence of diagnosis on the prescriptions and the duration of treatment were most commonly observed.

CONCLUSIONS

Percentage of prescribing by generic name was low. Educational sessions for the doctors at different levels to encourage prescribing by generic names and on correct writing of prescriptions may be considered. Studies covering a larger number of patients and for a longer time period are required. A greater number of patients can be studied, seasonal variations can be overcome and drug utilization can be measured quantitatively.

A study on rational drug prescribing and dispensing in outpatients in a tertiary care teaching hospital of Western Nepal

OBJECTIVES

To analyze the prescriptions of out-patients for rational prescribing and dispensing and to evaluate the patient's knowledge regarding use of drugs, using INRUD indicators.

METHODS

A cross-sectional, descriptive study was conducted at the Manipal Teaching Hospital, Pokhara, Nepal during the time period from June 10th to August 19th 2004.

RESULTS

Totally 247 prescriptions were randomly selected for analysis, wherein 720 drugs were prescribed. Only 15% of drugs were prescribed by generic name, 21.67% of the total drugs consisted of fixed-dose combinations, only 40% of drugs were from the Essential drug list of Nepal and 29.44% (n=212) were from the WHO Essential drug list. It was found that more than half (54.17%) of the drugs were from Nepalese National Formulary and 35.69% were from WHO model formulary. Dermatological products were most commonly prescribed followed by drugs acting on central nervous system, antimicrobials and drugs acting on cardiovascular system. Among the drugs dispensed, 79.16% were oral followed by topical (18.19%) and parenteral forms (2.98%). Diagnosis was mentioned only in 3.23% (n=8) of the prescriptions and the average cost per prescription was found to be 241.11 Nepalese rupees (US$ 3.26). It was found out that pharmacist labelled only 0.4% of the medication envelopes with the name of the patient. However, 82.6% of the medication envelopes were labelled with name of the drug and 87.0% with drug strength. Only 53.8% (n=133) of the patient knew both the duration of the therapy and administration time of drugs.

CONCLUSION

There is a need for educational intervention for prescribers and both managerial and educational intervention for the hospital pharmacists to improve prescribing and dispensing.

Anomalous branching of the axillary artery: a case report

We present a case regarding the anomalous branching in the third part of the axillary artery on the left side in a 35-year-old male Nepalese cadaver. In the third part the axillary artery divided into superficial brachial and deep brachial arteries. The superficial brachial artery continued in the arm without giving any branches and ended in the cubital fossa dividing into radial and ulnar arteries. The deep brachial artery gave rise to subscapular, profunda brachii, articular branch to the shoulder joint, anterior circumflex humeral artery and posterior circumflex humeral artery. This variation is very rare and incidence is around 0.12-3.2% in the available literature. The normal and abnormal anatomy of the axillary region is having practical importance for the vascular radiologist and surgeon and it should be known for accurate diagnostic interpretation.

Morbidity profile and prescribing patterns among outpatients in a teaching hospital in Western Nepal

BACKGROUND

Recent studies on prescribing among outpatients in hospitals in Western Nepal are lacking. The main objectives of the study were to obtain information on the morbidity pattern among outpatients and to analyze prescribing using drug use indicators.

METHODS

A retrospective hospital record based study from 01.01.2004 to 31.12.2004 was carried out among individuals attending the outpatient department (OPD) of the Manipal Teaching hospital, Pokhara, Western Nepal. A total of 32,017 new patients attended the OPD during the study period. Systematic random sampling (1 in every 20 patients) was done and 1600 patients selected. After excluding patients visiting the emergency department, those who got admitted and whose records were not available, 1261 cases were analyzed. The demographic details, morbidity pattern, average number of drugs prescribed, percentage of drugs prescribed by generic names and from the Essential drug list of Nepal (Essential drugs are those which satisfy the priority healthcare needs of the population), percentage of encounters with an antibiotic and an injection prescribed were noted.

RESULTS

1261 patients made 1772 visits. Upper respiratory tract infection and acid peptic disease were the most common diagnoses. The mean number of drugs was 1.99. Only 19.5% and 39.6% of drugs were prescribed by generic name and from the Essential drug list. Antibiotics and injections were prescribed in 26.4% and 0.96% of encounters. Cetrizine, vitamins, amoxicillin, the combination of paracetamol and ibuprofen and ranitidine were most commonly prescribed.

CONCLUSIONS

Upper respiratory tract infections and acid peptic disease were the common illnesses. Generic prescribing and use of essential drugs were low. Some of the drug combinations being used were irrational. Prescriber education may be helpful in encouraging rational prescribing.

Learning styles of preclinical students in a medical college in western Nepal

OBJECTIVES

Information on the learning styles of medical students are lacking in medical colleges in Nepal. Learning styles may be associated with student understanding and may predict success in examination. The present study was carried out to obtain information on learning styles and preferences for teaching of fourth semester medical students and note the association, if any, between respondents' personal characteristics and preferences for learning styles and types of teaching. The correlation between preferences for learning styles and types of teaching and performance in the second year university examination was also explored.

METHODS

The study was carried out during October 2003 at the Manipal College of Medical Sciences, Pokhara, Nepal using the Approaches and Study Skills Inventory (ASSIST) instrument. Information on the respondents' personal characteristics was collected. Respondents had to indicate their degree of agreement with a set of statements using a modified Likert-type scale. The statements were grouped into three main learning styles and two types of teaching. The median scores among different subgroups of respondents were compared using appropriate non-parametric tests (p<0.05).

RESULTS

Ninety-two students (92%) participated; fifty-six were male. Thirty-one respondents were Nepalese, 48 were Indians. Majority were educated in English medium schools. The median scores for deep and surface learning styles were 64 and 49 respectively (maximum score=80). The scores for strategic learning was 75.5 (maximum score=100). There was no clear preference for any particular type of teaching. Indian students used more surface apathetic learning strategies compared to others. There was a negative correlation between surface learning and marks obtained in the final examination.

CONCLUSIONS

The students mainly used deep and strategic learning styles. Differences in preference for learning styles and types of teaching were noted according the respondents' personal characteristics. This was a preliminary study and further studies are required.

Cerebellar control of visceral responses-possible mechanisms involved

It seems reasonable to assume that cerebellar autonomic control operates according to similar principles as those utilized in the somatomotor coordination. The unique and very uniform neuronal architecture throughout the cerebellum speaks in favour of such a view.

Prescribing patterns among paediatric inpatients in a teaching hospital in western Nepal

INTRODUCTION

Infants and children constitute a large proportion of the population in developing countries. In Nepal, studies on drug use patterns in the paediatric age group are lacking in hospitals in the western region. The present study was carried out to obtain demographical information and information on the prescribing patterns of drugs. The antibiotic sensitivity patterns of commonly-isolated micro-organisms and the mean cost of drugs were obtained.

METHODS

The study was carried out over a four-month period (December 1, 2003 to March 31, 2004) at the Manipal Teaching Hospital, a tertiary care hospital in Pokhara, western Nepal. The case records of patients discharged from the paediatrics ward during the study period were analysed. Mean number of drugs prescribed was calculated. The percentage of admissions that were prescribed antibiotics was determined.

RESULTS

356 patients were admitted during the study period, of which 228 were male. The median duration of hospitalisation was four days. The mean number of drugs prescribed per admission was 4.5. 789 drugs (48.9 percent) were prescribed by the parenteral route. Antibiotics were prescribed in 249 admissions (69.9 percent). Staphylococcus aureus, Escherichia coli, and Acinetobacter species were the common organisms isolated, and were resistant in some cases to the commonly-used antibiotics. The mean (+/- standard deviation) cost of drugs per admission was 5.4 (+/-1.6) US dollars.

CONCLUSION

Prescribing by generic name should be encouraged. Use of parenteral antibiotics was high and route conversion programmes should be instituted. Use of antibiotics for predominantly viral infections should be reduced. Treatment guidelines for common conditions should be formulated.

Patient counseling by pharmacist - a focus on chronic illness

The management of chronic illness needs lifestyle modifications and drug therapy for a long period. Patient understanding regarding the illness plays a very important role in management of chronic illness. Effective patient counseling makes the patient understand his/her illness, necessary lifestyle modifications and pharmacotherapy in a better way and thus enhance patient compliance. The pharmacist has immense responsibility in counseling the patients with chronic illness. The counseling pharmacist should possess adequate knowledge and should be an effective communicator, making use of the verbal and non-verbal communication skills.

Initiating and strengthening medical student research: time to take up the gauntlet

Self-directed learning and evidence-based medicine are becoming increasingly important in medical education. Medical student research projects can enable students to learn research methodologies and critical analysis skills. Medical schools in developed countries have introduced research programmes for medical students. A few medical colleges in developing countries have initiated student research programmes. South Asia has a huge population and massive health problems and research may be helpful in finding solutions. Student research can contribute to the published output of institutions. Research projects can help students to develop critical analysis skills, teach them to write for peer-reviewed publications and can foster student-faculty interaction. In Nepal, opportunities and funding for research are limited. Principles of scientific research should be taught to students. A community research project should be made compulsory. Funding for research should be boosted and infrastructure strengthened. Faculty members actively involved in research can serve as powerful 'role models'. Marks should be allotted for research projects and students must be encouraged to publish their findings. Publications and projects should be considered during admission to postgraduate courses. Student research should be initiated, actively pursued and strengthened.

Safety monitoring of drugs--where do we stand?

Drug related complications, a major cause of hospitalizations, lead to huge economic burden and significant human suffering. New chemical entities enter the market without sufficient safety data on patient population making rare (Adverse Drug Reactions) ADRs undetected in the clinical trials. ADR monitoring helps in detecting the occurrence of rare and unknown ADRs and helps in prevention of further occurrence. Several methods are adopted for effective monitoring of ADRs. An effective ADR monitoring program requires adequate infrastructure and trained manpower. In developed countries, the ADR monitoring system is well established. In Nepal, the concept of ADR monitoring is in the infant stage. A simple approach for ADR monitoring may be helpful in starting an ADR monitoring program in hospital setups in Nepal. Though it is difficult to prevent ADRs, a systematic approach will definitely helps in minimizing the further occurrence of similar ADRs.

Contribution of the regional drug information center towards drug safety

Drug related complications may lead to huge economic impact and cause significant morbidity and mortality. The present study analyzed the services provided by our Drug Information Center (DIC) in relation to drug safety. Over a period of one year, the DIC received 336 drug related queries. Among these 127 queries were related to drug safety. Medical doctors asked 78% of queries and patient care was the purpose behind 64.6% of them. Half (50%) of the enquirers submitted their queries to the center personally or contacted the DIC staff. Forty one percentage of the queries were related to the causality of particular drug towards adverse drug reactions and 10 % regarding drug use in pregnancy and lactation. Centrally acting drugs accounted for 21% of the queries. Twenty two percentage of the enquirers required an immediate answer. DICs by providing unbiased and objective information can reduce the occurrences of drug related complications.

Attitudes of first-year medical students towards the doctor patient relationship

In recent years, medical schools all over the world have instituted a variety of curricula to teach communication skills, professional values and ethics to medical students. Studies on the student attitudes towards doctor-patient relationships are lacking in Nepal. The present study was carried out to obtain information on the sharing and caring dimensions of the doctor-patient relationship and note any association of the dimensions with the demographic characteristics of the respondents. The study was carried out among first year students of the Manipal College of Medical Sciences, Pokhara, Nepal in August 2003 using the patient-practitioner orientation scale. One hundred and sixty-five students participated. The mean +/- SD total, caring and sharing scores were 3.71 +/- 0.48, 3.51 +/- 0.55 and 3.91 +/- 0.62 respectively. Students whose first degree relative was a doctor had higher sharing score compared to those without doctor relatives. Female students had higher scores. Students had a positive attitude towards the doctor-patient relationship. Our scores were lower than those reported previously. Further studies are required and the results obtained will be helpful in designing a doctor-patient relationship course for Nepal.

Our experience with epidural steroid injections in management of low backpain and sciatica

BACKGROUND

Low back pain and sciatica is a common clinical condition. It is a most common orthopaedic complaint in the Kaski region of Nepal. The reason for its increased incidence may be hilly terrain, difficult working and living environment of the region. The initial treatment of Low back pain is conservative. Epidural steroid injection is being slowly established as are liable mode of conservative management in many orthopaedic centres of the world. This is a preliminary report of on-going study of the use of epidural steroid in the management of low back pain cases coming to the orthopaedic department of Manipal Teaching Hospital.

METHODS

Prospective clinical trial was carried out on the patients reporting with low back pain and sciatica not responding to other modes of conservative treatment. Pre and post injection evaluation was done clinically. The level of pain, improvement in physical signs and ability to do activities of daily living were noted.

RESULTS

Fifty two patients were observed for the average duration of 2.87 months. Average duration of symptoms was for 10 months. After first epidural steroid injection 83% of patients reported relief on day one. In some cases the onset of analgesia was delayed. Four patients reported no relief after first injection. Fifteen patients were given two injections and four received three injections. The average duration between two injections was three weeks. Average duration of pain relief was 20 days. At the end of 3 months, good results were seen in 39%, fair in 33% and bad results in 27%. Overall 59% of patients were able to do activities of daily living. Three patients (5.76%)required operation for disc prolapse. Postoperatively two patients reported back with back pain. Most common complaint of patients after injection was pain at the injection site. No major complications were encountered.

CONCLUSION

Epidural Steroid Injection is a safe and effective mode of treatment of Low Back Pain. It provides painfree period to enable the patient for physiotherapy which helps in early recovery.
