Infection prevention and control in tertiary care hospitals of Bangladesh: results from WHO infection prevention and control assessment framework (IPCAF)
Antimicrobial Resistance & Infection Control volume 11, Article number: 125 (2022)
Infection prevention and control (IPC) in healthcare settings is imperative for the safety of patients as well as healthcare providers. To measure current IPC activities, resources, and gaps at the facility level, WHO has developed the Infection Prevention and Control Assessment Framework (IPCAF). This study aimed to assess the existing IPC level of selected tertiary care hospitals in Bangladesh during the COVID-19 pandemic using IPCAF to explore their strengths and deficits.
Between September and December 2020, we assessed 11 tertiary-care hospitals across Bangladesh. We collected the information from IPC focal person and/or hospital administrator from each hospital using the IPCAF assessment tool.. The score was calculated based on eight core components and was used to categorize the hospitals into four distinct IPC levels– Inadequate, Basic, Intermediate, and Advanced. Key performance metrics were summarized within and between hospitals.
The overall median IPCAF score was 355.0 (IQR: 252.5–397.5) out of 800. The majority (73%) of hospitals scored as ‘Basic’ IPC level, while only 18% of hospitals were categorized as ‘Intermediate’. Most hospitals had IPC guidelines as well as environments, materials and equipments. Although 64% of hospitals had IPC orientation and training program for new employees, only 30% of hospitals had regular IPC training program for the staff. None of the hospitals had an IPC surveillance system with standard surveillance case definitions to track HAIs. Around 90% of hospitals did not have an active IPC monitoring and audit system. Half of the hospitals had inadequate staffing considering the workload. Bed occupancy of one patient per bed in all units was found in 55% of hospitals. About 73% of hospitals had functional hand hygiene stations, but sufficient toilets were available in only 37% of hospitals.
The majority of sampled tertiary care hospitals demonstrate inadequate IPC level to ensure the safety of healthcare workers, patients, and visitors. Quality improvement programs and feedback mechanisms should be implemented to strengthen all IPC core components, particularly IPC surveillance, monitoring, education, and training, to improve healthcare safety and resilience.
Infection prevention and control (IPC) in healthcare settings is imperative for the safety of patients as well as healthcare providers . IPC remains a cornerstone strategy for preventing hospital-acquired infections (HAI) and antimicrobial resistance (AMR) . HAIs are associated with high rates of morbidity and mortality, affecting over 1.4 million patients annually around the globe and carrying a projected mortality of over 10% [3,4,5]. Low- and middle-income countries (LMIC) face an undue burden of HAIs with up to 25% of hospitalized patients experiencing HAIs compared to 7% in the high-income countries [6, 7]. These infections heavily strain health systems and incur rising direct and indirect costs [5, 8].
Like many LMICs, IPC practices in Bangladesh have been hindered by overcrowding, understaffing, inadequate environmental cleaning, insufficient hand washing stations, low compliance with recommended hand hygiene practices, poor ventilation, and lack of IPC training [9, 10]. This has resulted in high rates of HAIs. In one study from Bangladesh, 5% of patients hospitalized for > 72 h acquired a hospital-acquired respiratory illness . HAIs can also affect healthcare workers. The same study , documented 27% of healthcare workers experienced a respiratory illness during the study period. Another study reported that 2.6% of hospitalized patients and 4% of healthcare workers developed hospital-acquired diarrhea . Other studies from Bangladesh have estimated overall rates of HAIs ranging from 8 to 30%, exacerbated by inadequate IPC [13,14,15].
The recent COVID-19 pandemic further exposed the gaps in IPC to prevent HAIs. Despite various infection control measures, up to 44% of SARS-CoV-2 infections early in the outbreak were hospital-acquired . In Bangladesh, 9455 frontline health workers have been infected, and 180 physicians died from COVID-19 between March 2020 and December 2021, which indicates substantial deficits in IPC practices [17, 18]. However, throughout the pandemic, hospitals have enhanced IPC efforts leading to fewer hospital-acquired SARS-CoV-2 infections, demonstrating the effectiveness of this strategy against epidemic as well as endemic diseases .
Additionally, AMR has been inextricably linked to HAIs in LMIC settings . In 2019, bacterial AMR was directly responsible for around 1.27 million fatalities worldwide and attributable for an estimated 495 million (362–657 million) deaths without infection . AMR is anticipated to result in 9 million excess deaths and a financial loss of $100 trillion in LMICs by 2050 . HAIs and AMR transmission in healthcare settings can be prevented by implementing systematic and effective IPC initiatives [23, 24]. Moreover, IPC is a cost-effective strategy to reduce infections in healthcare settings . Despite substantial progress to minimize HAIs in many parts of the world, several recent events have highlighted the need to improve IPC at both the national and facility levels . In light of this concern, in 2018, WHO released an evidence-based tool on IPC core components titled “The Infection Prevention and Control Assessment Framework (IPCAF)” to assess, analyze, and enhance the IPC activities of a hospital facility . The overall IPCAF score indicates the level of IPC standards of a hospital . Using this framework and the set of tools, healthcare facilities would be enabled to evaluate existing IPC processes and infrastructure and detect relevant problems and shortcomings that require improvement. In Bangladesh, limited systematic evaluations of IPC have been conducted at the national or facility level. This study aimed to assess the current IPC standards and find out the gaps of selected tertiary care hospitals in Bangladesh using the IPCAF tool and identify steps for IPC improvement during the COVID-19 pandemic and beyond.
Methods and materials
Study design and study sites
We conducted this cross-sectional survey from September-December 2020. After discussion with the Director-General of Health Services (DHGS), hospital leadership teams, and subject matter experts, we purposively selected 11 tertiary hospitals (bed occupancy ranged from 450 to 2600) across Bangladesh that demonstrated a commitment to enhancing IPC. These hospitals were purposively selected by the government authorities (DGHS) to implement the IPC pilot intervention, which is around 25% of total tertiary care health facilities in Bangladesh, Face-to-face interviews were conducted from respective hospitals with the IPC focal person and/or hospital administrator who had IPC-related expertise.
Data collection tool—IPCAF
We used the IPCAF tool to assess the current IPC level and resources in selected hospitals. IPCAF is a structured, closed-ended questionnaire with an associated scoring system. This is an established tool to measure IPC activities and identify relevant strengths and weaknesses at acute health care facilities . It comprises eight sections highlighting the eight IPC core components (CC). The results of each question are aggreagated within the eight CCs, with possible scores ranging from 0 to 100 for each CC. The overall IPCAF score was obtained by summing the findings of all eight core components. The eight CCs of the IPCAF questionnaire are as follows:
CC1: IPC program
CC2: IPC guidelines
CC3: IPC education and training
CC4: HAI surveillance
CC5: Multi-modal strategies for implementation of IPC interventions
CC6: Monitoring/audit of IPC practices and feedback
CC7: Workload, staffing, and bed occupancy
CC8: Built environment, materials, and equipment for IPC at the facility level
These eight core components include a total of 81 indicators. Based on the overall score obtained, the respective facility was categorized into one of four IPC promotion levels (Table 1).
We completed data entries through MS-Access. For categorical results, descriptive analysis was conducted using a frequency and cross-tabulation analysis. We summarized the indicators by frequency, percentage, and median with interquartile range. Statistical software STATA version 15.0 (STATA Corp Inc., Texas, USA) was used to perform the analyses.
All 11 healthcare facilities were tertiary care hospitals, with average bed capacities ranging from 620 to 970. In terms of facility ownership and management, nine of the facilities were public hospitals and two were private hospitals (Table 2). The selected healthcare facilities are also teaching hospitals with huge patient loads. The hospitals have key departments and equip modern healthcare facilities. These are also the referral hospitals, and patients from sub-district and district-level hospitals get admission to these hospitals.
Distribution of IPCAF score
The overall median IPCAF score for the participating hospitals was 355.0 (IQR: 252.5–397.5). The two hospitals with the highest IPCAF scores (522.5 and 482.5; Fig. 1) obtained ‘Intermediate’ IPC levels according to the WHO reference range on IPCAF classification. Eight (72.7%) hospitals scored as ‘Basic’ IPC levels, whereas one hospital fell into the ‘Inadequate’ category with a score of 192.5 (Fig. 1).
Based on core component score distribution, the highest median score (67.5) was recorded for both IPC Guidelines (CC2) and Built environment, equipment, and material for IPC (CC8), while HAI Surveillance (CC4) had the lowest score [median 5.0, IQR: 0, − 23.8]. The widest variability was found for IPC guidelines (CC2) and IPC education and training (CC3), and the narrowest for the built environment, equipment, and material for IPC (CC8) (Table 3).
IPC program (CC1)
The calculated median score for IPC programs was 50.0 (IQR: 37.5–61.3). About three-fourth of hospitals (72.7%) had an IPC program, but only 18.2% hospitals had this program with clearly defined IPC objectives and annual activity plans. The IPC program was supported by a designated professional and/or an IPC committee in less than half of the hospitals (45.5%). Support for IPC goals and indicators (i.e., at executive level meetings, executive rounds, participation in morbidity and mortality meetings) was demonstrable in 36.4% of hospitals. As for microbiological laboratory support, 9 out of 11 hospitals had laboratory capacity for delivering results reliably (timely with sufficient quality), and less than half of the hospitals had IPC program-specific budget allocations (Table 4).
IPC guidelines (CC2)
CC2 had the highest median score at 67.5 (IQR: 48.8–76.3). Hand hygiene guidelines were available in all hospitals while guidelines for disinfection, sterilization, and waste management were found in 90.9% of hospitals. Only 9.1% of hospitals had antibiotic stewardship guidelines. Around half of the hospitals (54.5%) had guidelines for transmission-based precautions, surgical site infection prevention, and injection safety. Where these guidelines were available, they were consistent with national/international guidelines in most of the hospitals (81.8%). For IPC activities, 63.6% of hospitals had the expertise for developing or adapting IPC guidelines. In 45.5% of hospitals, healthcare providers received specific training on updated IPC guidelines, including regular monitoring systems for guideline implementation (Table 4).
IPC education and training (CC3)
IPC education and training varied highly among the study hospitals (median score 30.0, IQR: 25.0–57.5). IPC experts for training were found in more than half of the hospitals (54.5%), though healthcare workers in a significant number of hospitals (36.4%) never or rarely received any IPC training. The cleaners and administrative staff did not participate in any training on IPC in 45.5% and 63.6% of hospitals, respectively. Only 18.2% of hospitals had arrangements for specific IPC training for patients and their family members (Table 4).
HAI surveillance (CC4)
HAI surveillance received the lowest score in the facility assessment, with a median of 5.0 (IQR: 0–23.8). None of the hospitals had a surveillance system as a defined component of IPC, nor did they use a standardized case definition for surveillance of HAIs. All hospitals cited a lack of necessary IT support and specialized professionals skilled in epidemiology to carry out surveillance. Only two hospitals conducted regular analysis for antimicrobial drug resistance patterns (Table 4).
Multi-modal strategies (CC5)
The majority of hospitals (72.7%) were found to use multi-modal strategies for the implementation of IPC activities and the median value for CC5 recorded 35.0 (IQR: 32.5–52.5). More than half of the hospitals (54.5%) had monitoring compliance maintained with outcome indicators. Managers showed visible support only in few hospitals (27.3%) for safety climate and culture change. In all hospitals except one, reminders, posters, or awareness-raising tools were used to promote interventions. However, less than one-third of hospitals (27.3%) had multi-disciplinary teams for the implementation of various strategies (Table 4).
Monitoring and audit of IPC practices and feedback (CC6)
CC6 had a median value of 45.0 (IQR: 26.3–48.8), which indicates a lack of monitoring and audit practices in study hospitals. In the majority of hospitals (90.9%), monitoring plans with clear goals, targets, or activities, including trained monitoring persons were absent. The most monitored indicators were disinfection and sterilization of medical equipment and cleaning of ward environments (81.8%) followed by hand hygiene compliance (72.7%) and wound dressing changes (63.6%). Only two hospitals conducted the WHO hand hygiene self-assessment survey, of which one hospital had annual reporting of monitoring data (Table 4).
Workload, staffing, and bed occupancy (CC7)
The median score for workload, staffing, and bed occupancy was 40.0 (IQR: 27.5–50.0). Staffing level assessments were found in only 27.3% of hospitals. Around 55% of hospitals maintained the WHO/national proposed ratio for healthcare workers to patients in around half of their total units. More than half of the hospitals (54.5%) had availability of one patient per bed for all units. Less than one-third hospitals (27.3%) maintained adequate spacing (> 1 m) between patient beds for all units (Table 4).
Built environment, materials, and equipment for IPC (CC8)
The built environment, materials, and equipment were frequently conducive to maintaining IPC with a median score of 67.5 (IQR: 56.8–72.3). Around 90.9% of hospitals had available water services with sufficient quantity, and reliable and accessible safe drinking stations were found in 63.6% of hospitals. Regarding ventilation systems, all the hospitals had functional environmental ventilation (natural or mechanical) available in patient-care areas. Functional hand hygiene stations with reliably accessible supplies of alcohol-based hand-rub solution or soap and single-use towels were present at the majority of the hospitals (72.7%). Single room for cohorting was available only in 18.2% of healthcare settings, and over half of the hospitals maintained a sufficient and continuous PPE supply. Functional waste collection containers were found at waste generating points in 63.6% of settings, but only two hospitals had functional incinerator or wastewater treatment systems. More than 88% of hospitals possessed sufficient reliable equipment that was sterile and disinfected for daily usage (Table 4).
We assessed the existing IPC level of selected tertiary care hospitals in Bangladesh using the WHO IPCAF tool. There are very few studies conducted in South Asian countries, including Bangladesh, using the IPCAF tool to assess the IPC condition in tertiary care hospitals. This assessment has provided us with valuable insights into the actual scenario of key IPC structures, implementation, and processes in these healthcare settings. Findings from other studies have revealed that adherence to proper IPC measures can reduce the incidence of HAIs by up to 70% in healthcare settings . This assessment revealed that most facilities only met a basic IPC level  which is consistent with a recently conducted global study . While some aspects (IPC guidelines, IPC environment, material, equipment, IPC program) of the IPC core components were frequently in place, not all were sufficiently implemented, indicating that substantial improvement is required.
Although it was not designed in response to COVID-19, the co-occurrence of the pandemic underscored the importance of IPC and the need to identify opportunities for improvement.PPE deficits may have been exacerbated by the tremendous global supply chain gaps that emerged as the demand for PPE in response to SARS-CoV-2 grew. Regardless, the findings from this study identify ongoing crucial IPC deficiencies prevailing at tertiary hospitals that likely contributed to nosocomial cases of SARS-CoV-2. The resilience of healthcare facilities in containing and treating disease without propagating infectious threats will depend on enhancing IPC practices in response to regular assessments such as was conducted in this study.
Two hospitals attained intermediate IPC levels. These facilities were remarkable for obtaining higher scores in most of the indicators compared to other hospitals. Only one facility ranked at the inadequate IPC level. No facility achieved an advanced IPC level. Therefore, we observed a profound degree of heterogeneity through this facility-level IPC assessment. These results of IPC capacityare similar to other facility assessments conducted in South Asia and other middle-income countries  and are concerning.
Regarding the IPCAF scores, marked differences occurred among IPCAF core components between the tertiary care hospitals. IPC programs (CC1) were frequently present, though the deliverables of these programs are less clear given the lack of defined objectives and annual activity plans. This highlights the need for strategically delineating the deliverables of an IPC program to ensure its impact. Other studies also have testified that an IPC program’s success depends on clear communications and the specification of objectives . Additionally, less than half of the hospitals had an IPC team comprising of dedicated IPC professionals to support the IPC program; all the designated individuals were temporarily appointed. This reveals an inadequate institutional commitment to strengthening IPC, which is supported by the fact that less than half of the facilities had an allocated budget for conducting IPC activities. Similar deficits in budget allocations have been observed in a global situational analysis, revealing this to be a widely pervasive challenge . There always has been a direct relationship between the availability of funds and increased IPC preparedness. An IPC programme with dedicated team and governance, is crucial to reduce the spread of infectious diseases in the hospital setting . Lack of allocated money, lack of clear and specific objectives to run the program, and lack of dedicated IPC teams demonstrate the need for greater IPC prioritization. In collaboration with Directorate General of Health Services (DGHS), the hospital authorities can enhance the institutional commitment through contextualized IPC programs with priority-based objectives and designated teams.
Although IPC guidelines (CC2) were commonly available, antibiotic stewardship guidelines were found only in one hospital. This might be a contributing factor to physicians’ lack of knowledge towards rational prescribing of antibiotics . The establishment of an antibiotic stewardship program (ASP) could be an essential step in educating clinicians to optimize the use of antibiotics for effective treatment of infections and protect patients from antibiotic resistance . IPC training and education (CC3) were less frequent and sometimes absent, despite being six months into the COVID-19 pandemic. A study from Bangladesh also highlighted that healthcare workers were not receiving quality and sufficient training around IPC, with 85% of participants reporting they received no formal training on infection control . Regular IPC training was also found to be lacking from studies in Ghana, Pakistan, and even Austria [29, 36, 37]. These findings demonstrate that the importance of regular IPC training may not be well understood by hospital administration or that IPC experts to facilitate such training are lacking. Cleaners, who are a core part of hospital staff and significantly contribute to maintaining hospital hygiene, were found to receive IPC training even less frequently than healthcare workers in our study. This finding is consistent with a study conducted in Turkey where about 57% of the cleaners did not receive any formal training on infection control . The hospitals should regularly arrange motivation sessions and hands-on IPC training for all the staff, particularly for cleaners.
HAI surveillance (CC4) was found to be routinely lacking, stemming from inadequate microbiology and lab capacity, lack of IT support, and absence of experts trained in basic epidemiology. HAI surveillance cannot be effectively conducted if each of these parameters is not in place. Hospital-based surveillance allows the estimation of local burden and incidence of HAI so that appropriate IPC measures can be taken [4, 39]. Given the known burden of antimicrobial drug resistance in admitted patients with HAIs , such a scenario ultimately puts the patients at risk of receiving inappropriate care. HAI surveillance should be improved by concurrent building capacity in laboratory diagnostics and epidemiologic methods.
Multi-modal strategies (CC5) is a comparatively new concept that is gradually becoming more prevalent in IPC practice [41,42,43]. Most of the hospitals achieved a low score for this component, which indicates the lack of awareness about the need to have a multi-disciplinary team to provide inputs on and implement a variety of strategies. The low utilization of multi-modal strategies may arise because of a lack of interdepartmental cooperation. Studies conducted in Pakistan, Austria, and Germany also reported similar findings, although the last two countries were in high-income settings and technologically more advanced than Bangladesh [29, 36, 44].
Study facilities varied in monitoring and auditing of IPC practices (CC6) as well as workload, staffing, and bed occupancy levels (CC7). A well-defined monitoring plan with proper goals, targets, and activities was absent in all hospitals, except one public facility with a strong enforcement culture and greater structural and logistical support. None of the facilities provided regular feedback reports on IPC performance audits to any upper administration, which shows limited institutional investment in making improvements around IPC. Gilbert and Kerridge asserted that poor leadership often has a deep connection with a lack of proper IPC practices in the facility and negatively impacts the overall compliance rate . Nearly half of facilities demonstrated understaffing and overcrowding, which have been demonstrated to be significant risk factors for HAIs in many previous studies [46, 47]. Although the system may have been unusually burdened by surges of COVID-19, previous studies from Bangladesh have demonstrated similar rates of deficiencies on these metrics . Overcrowding and inadequate staffing in these hospitals reveal another opportunity for improvement in IPC practices but require high-level institutional support and planning. The policymakers should fill up vacancies on a priority basis and foster the recruitment process until a standard patient to staff ratio is obtained.
The last core component (CC8) assesses the infrastructure, materials, and equipment for optimum IPC practices in a healthcare setting. Data showed that the hospitals' water, electricity, light, and ventilation (mechanical or natural) system was generally satisfactory as more than 70% of the facilities had these amenities in abundance, which is consistent with Bangladesh’s status as a lower-middle-income country. However, some of the institutions were found to be lacking a sufficient number of functional toilets and hand hygiene stations with regular supplies of soap and hand rub solution. This may have resulted from decreased access to maintenance and repair services during the pandemic as service technicians may have been concerned about exposure to SARS-CoV-2 in healthcare facilities. The lack of functional hygiene stations can lead to poor compliance with hand hygiene among healthcare workers, which is in line with a study’s findings on hygiene practices in Bangladesh (48). Additionally, there was no validation of the adequacy of ventilation, which may have contributed to SARS-CoV-2 transmission. About half of the facilities were not able to provide an adequate amount of PPE for protecting the healthcare workers. A regular supply of sufficient PPE is crucially important both for the safety of patients and staff and also to interrupt disease transmission. The existing scenario may have been exacerbated by disruptions to PPE supply chains that were caused by the pandemic but also placed healthcare workers at heightened occupational risk. Availability of cleaning materials may be one of the simplest and least expensive ways to improve IPC, though these were far from universally available, posing an ongoing threat to the spread of HAIs. The hospital authorities should regularly track and maintain an PPE supply and ensure the optimum use of PPE through monitoring.
Strengths and limitations
The study provided us with an opportunity to capitalize the IPCAF tool at an expanded range to assess the present IPC situation and identify critical gaps towards IPC implementation in tertiary hospitals. These findings can be used to help policymakers increase investment in and prioritization of IPC to ensure the safety of healthcare workers in Bangladesh during the COVID-19 pandemic and beyond.
A limitation of this study is that it was carried out in selected tertiary hospitals of Bangladesh which does not provide a nationwide representative result. Incorporating hospitals in different regions that offer varying levels of care could have revealed greater heterogeneity in existing IPC level. Furthermore, many of the indicators were based on self report by a designated IPC person. The assessments could be made more robust with objective data to support their determinations. However, this assessment was carried out in late 2020 when the entire world was experiencing a global pandemic. Because the pandemic generated heightened awareness around IPC, the findings from this assessment may be elevated compared with normal time.
By revealing the current state of IPC preparedness and shortcomings in tertiary care hospitals, this study can provide a useful framework for policymakers to not only assess the current scenario but also to design strategic improvement plans. This study demonstrates clear areas of need that could benefit from enhanced commitment and stakeholder engagement. The data suggests that the area in most need of improvement is CC4 HAI Surveillance as it is the core components for some of the other CCs. The higher scores in other areas suggest the need to improve assessment methodology as it is problematic to have high scores without adequate CC4 HAI Surveillance data. For establishing an effective IPC system, national IPC standards have to be upgraded first with context-specific training and close monitoring of collected data. Participants from all designated disciplines should collaboratively design and champion a diverse set of approaches to make IPC programs a success.
