There were 167 hospitals with general surgical services in 2010. The general surgeon to population ratio in Malaysia for 2010 was 0.06 per 10,000 population, far below that of developed countries. The distribution of the general surgeons was fairly uniform between the public and private sector. The urbanised west coast states of Peninsular Malaysia had the highest concentration of surgical services provided by private hospitals. However, in the distribution of surgical services, public hospitals were somewhat more uniform throughout the country. The nature of surgical procedures undertaken showed a significant variation, with public hospitals performing the highest numbers of emergency surgeries (for example, appendicectomies and trauma-related laparotomies) and private hospitals mainly performing elective surgeries (for example, cholecystectomies and thyroidectomies). In terms of surgical approach, surgeons at private hospitals performed more laparoscopic cholecystectomies and laparoscopic appendicectomies when compared to surgeons working at public hospitals. Overview Surgery is an essential component of basic health care and is currently considered an integral part of primary health care. It provides an effective way of dealing with various clinical conditions such as injuries, acute infections, tumours and malignancies, various congenital defects and deformities. General surgical services in this survey includes the specialty of general surgery and its various subspecialties of breast and endocrine, upper gastrointestinal, colorectal, vascular, hepatobiliary, trauma and cardiothoracic surgeries. This survey was undertaken in all Ministry of Health, university and private hospitals in Malaysia, with general surgical services being provided by resident or visiting general surgeons. In addition, hospitals with visiting surgeons were only included if elective surgery was performed in their establishments. Facilities One hundred and sixty seven hospitals providing general surgical services in Malaysia; 60 from the public sector, including 3 university hospitals, and 107 from the private sector. The response rate to this survey was 100% from public hospitals and 66 % from private hospitals. This study revealed that on average 0.06 hospitals per 10,000 population provided general surgical services. The surgical services were most concentrated in Wilayah Persekutuan Kuala Lumpur (WPKL) (0.13 per 10,000 population), followed by Pulau Pinang (0.10 per 10,000 population), Negeri Sembilan (0.08 per 10,000 population) and Perak (0.06 per 10,000 population) respectively. These states also had the highest concentration of private hospitals providing surgical services. The ratio of surgical services in the other states ranged from 0.03 to 0.06 hospitals per 10,000 population with Sabah having the lowest concentration of surgical services (0.03 per 10,000 population) (Table 5.1). There were a total of 901 operating rooms in Malaysia, 529 (59%) in public hospitals and 372 (41%) in private hospitals. The overall distribution of operating rooms in Malaysia was 0.32 per 10,000 population with widely disparate distribution of operating rooms between Pulau Pinang, WPKL, Melaka, Selangor and Putrajaya compared to Sabah, Sarawak and Perlis. This disparity was partly due to the operation rooms contributed by the higher concentration of private hospitals in the urbanised west coast states of Peninsular Malaysia. This survey also revealed that at least 15% of the operation rooms in the country were non functional. This was probably due to the lack of human resources and/or infrastructural defects and deficiencies. Most of the public hospitals had at least one dedicated trauma/emergency operation theatre. However, there was an overall lack of dedicated surgical high dependency beds in most hospitals in the country (Table 5.2). Surgical Services in Malaysian Hospitals 5 59 NATIONAL HEALTHCARE ESTABLISHMENTS & WORKFORCE STATISTICS 2010 HOSPITALS Activities Elective Operating Hours The elective operating hours were better defined in the public hospitals as opposed to the private hospital where there was no distinct separation of elective and emergency operating hours. Thus, reporting of elective operating hours was strictly confined to the public hospitals. The average elective operating hours was 4.78 hours per surgeon per week. There was significant variation (ranging from 2.21 to 13.60 hours per surgeon per week) in the number of elective operating hours throughout the country. This variation was due principally to the differing numbers of surgeons (including subspecialty trainees) sharing the available operating time and also hinges on the availability of anaesthesiologists. Hospitals with higher numbers of trainees had a correspondingly lower ratio of operating hours per surgeon. In some states, both local anaesthesia (LA) and general anaesthesia (GA) cases were being reported, thus, giving higher ratios of elective operating hours. To overcome such reporting disparity, future data collection should strictly define this variable as elective operating hours under general or regional anaesthesia and should exclude elective operating hours under local anaesthesia (Table 5.3). General Surgery Operations The data on some common general surgical procedures performed in the country were also collected in order to assess the distribution of general surgery workload. In 2010, a total of 33,935 appendicectomy operations were performed in the country, 18,536 (54.6%) in public and 15,399 (45.4%) in private. Twenty percent of these appendicectomies were performed laparoscopically; a majority of which were done in the private hospitals. The low numbers of such operations performed in Sabah and Sarawak may not be truly reflective of the situation as data was only collected from those hospitals that had resident or visiting surgeons while it excluded data from non specialist public hospitals where most of the emergency and minor elective surgeries were undertaken by medical officers (Table 5.4). In 2010, a total of 2,343 laparotomies were performed for trauma. A majority of these operations were performed in public hospitals (1,631 in public and 712 in private hospitals) (Table 5.5). A total of 3,566 mastectomies were reported in 2010 and a majority of these were performed in the three tertiary breast centres; Hospital Putrajaya (n=130), Hospital Kuala Lumpur (n=296) and University Malaya Medical Centre (n=195) (Table 5.5). An average of 1 mastectomy performed per 10,000 population in Malaysia was low when compared to the European Community Health Indicators (ECHI) data that reported 5 mastectomies per 10,000 population1. This gap may be due to the differences in incidence rates of breast cancer in Europe and Malaysia. A total of 14,120 inguinal hernia operations were reported in 2010. These were almost equally distributed in the public and private hospitals (Table 5.6). Only 1,215 (8.6%) of the inguinal hernia repairs were performed laparoscopically, giving a ratio of 5 cases per 10,000 population, which was much less than in European countries that reported 23 cases per 10,000 populations1. A total of 9,909 cholecystectomies were performed in 2010, 2,924 in public and 6,985 in private, of which 7,601 (76.7%) were performed laparoscopically in the private hospitals (Table 5.7). ECHI data reveal almost 10 times more cholecystectomies being performed laparoscopically, giving an average ratio of 26 cases per 10,000 population1, compared to Malaysia where only 3 cases per 10,000 population were undertaken laparoscopically. In 2010, a total of 5,114 thyrodectomies were reported in Malaysia, of which 1,882 (36.8%) were performed in public hospitals and 3,232 (63.2%) were performed in private hospitals Based on this survey, it is apparent that the majority of emergency surgeries (appendicectomies and trauma related laparatomies) were performed in the public healthcare system while most elective surgical procedures (cholecystectomies and thyroidectomies) were performed in the private hospitals. There were a total of 1,969 cases of post operative mortality reported in this survey. The majority (88%) of it occurred following emergency surgeries. The post operative mortality rate for elective surgery in 2010 was 0.08 per 10,000 population (Table 5.8). General Surgery Workforce For the year 2010, there were 539 general surgeons in the country. Of these, 302 (56%) served in the public and 237 (44%) in the private hospitals (Table 5.9). The general surgeon to population ratio in Malaysia
