Communicable and gastrointestinal diseases followed by respiratory diseasesare the main reasons of admission in medical ward of developing countries. This is different fromthe developed countries where non communicable diseases are the main reasons of hospitaladmission. In developing countries the data of hospital admission are still lacking. Therefore thisstudy will help us to assess the common patterns of diseases admitted in a medical ward, theaverage length of hospital stay etc. Objective: The objectives of this study are to assess thepatterns and prevalence of diseases, the most common diagnosis and average duration ofpatient’s hospital stay. Design: Observational retrospective cross-sectional study. Patients andmethods: The record of 327 hospitalized patients in medical ward was analyzed for the period ofthirteen months from Mar 2013 to Mar 2014. Patient’s medical records were retrieved and dataanalysis was done to obtain age, sex, common diagnosis, the affected system and the duration ofthe hospital stay. The data was analyzed by using SPSSV 16. Results: After reviewing the data,the most common age of patients being admitted were between 46-65 yrs (37.6%), followed bybetween 26-45yrs (33%), < 25yrs (15.9 %) , between 66-85 yrs (12.5 % )and > 85 yrs were only1% . Among the admitted patients females were more than the males except in case of liverdiseases. The most affected system was gastrointestinal ( 22.63 % ) and the most commondiagnosis was Diabetes Mellitus (12.84 %). The next common system involved wascardiovascular (15.29 %), respiratory (14.37 %), endocrine / DM (10.70 %), neurology (9.48 %),heamatology (3.36 %), renal (2.45 %) , rheumatology (1.84 %) and others ( including pyschiarty ,poisoning, infectious , electric shock etc ) (5.81 %). The cause for hospital admission by infectionin different system was (20.48%) The average duration of hospital stay of the patients was 4 days.Conclusions: The gastrointestinal diseases and the infectious diseases are the most commondiseases. The communicable diseases still hold a greater position in developing countries, whilenon communicable diseases are main reasons for admission to the medical wards in developedcountries.
