Mortality, Morbidity and Health-Seeking Behaviour during the Ebola Epidemic 2014-2015 in Monrovia Results from a Mobile Phone Survey

Methodological issues of retrospective surveys for measuring mortality of highly clustered diseases: case study of the 2014-16 Ebola outbreak in Bo District, Sierra Leone

BACKGROUND

There is a lack of empirical data on design effects (DEFF) for mortality rate for highly clustered data such as with Ebola virus disease (EVD), along with a lack of documentation of methodological limitations and operational utility of mortality estimated from cluster-sampled studies when the DEFF is high.

OBJECTIVES

The objectives of this paper are to report EVD mortality rate and DEFF estimates, and discuss the methodological limitations of cluster surveys when data are highly clustered such as during an EVD outbreak.

METHODS

We analysed the outputs of two independent population-based surveys conducted at the end of the 2014-2016 EVD outbreak in Bo District, Sierra Leone, in urban and rural areas. In each area, 35 clusters of 14 households were selected with probability proportional to population size. We collected information on morbidity, mortality and changes in household composition during the recall period (May 2014 to April 2015). Rates were calculated for all-cause, all-age, under-5 and EVD-specific mortality, respectively, by areas and overall. Crude and adjusted mortality rates were estimated using Poisson regression, accounting for the surveys sample weights and the clustered design.

RESULTS

Overall 980 households and 6,522 individuals participated in both surveys. A total of 64 deaths were reported, of which 20 were attributed to EVD. The crude and EVD-specific mortality rates were 0.35/10,000 person-days (95%CI: 0.23-0.52) and 0.12/10,000 person-days (95%CI: 0.05-0.32), respectively. The DEFF for EVD mortality was 5.53, and for non-EVD mortality, it was 1.53. DEFF for EVD-specific mortality was 6.18 in the rural area and 0.58 in the urban area. DEFF for non-EVD-specific mortality was 1.87 in the rural area and 0.44 in the urban area.

CONCLUSION

Our findings demonstrate a high degree of clustering; this contributed to imprecise mortality estimates, which have limited utility when assessing the impact of disease. We provide DEFF estimates that can inform future cluster surveys and discuss design improvements to mitigate the limitations of surveys for highly clustered data.

Measuring under-5 mortality and fertility through mobile phone surveys: an assessment of selection bias in 34 low-income and middle-income countries

OBJECTIVES

This study aims to assess sample selection bias in mobile phone survey estimates of fertility and under-5 mortality.

DESIGN

With data from the Demographic and Health Surveys, we use logistic regressions to identify sociodemographic correlates of mobile phone ownership and access, and Poisson regressions to estimate the association between mobile phone ownership (or access) and fertility and under-5 mortality estimates. We evaluate the potential reasons why estimates by mobile phone ownership differ using a set of behavioural characteristics.

SETTING

34 low-income and middle-income countries, mostly in sub-Saharan Africa.

PARTICIPANTS

534 536 women between the ages of 15 and 49.

OUTCOME MEASURES

Under-5 mortality rate (U5MR) and total fertility rate (TFR).

RESULTS

Mobile phone ownership ranges from 23.6% in Burundi to 96.7% in Armenia. The median TFR ratio and U5MR ratio between the non-owners and the owners of a mobile phone are 1.48 and 1.29, respectively. Fertility and mortality rates would be biased downwards if estimates are only based on women who own or have access to mobile phones. Estimates of U5MR can be adjusted through poststratification using age, educational level, area of residence, wealth and marital status as weights. However, estimates of TFR remain biased even after adjusting for these covariates. This difference is associated with behavioural factors (eg, contraceptive use) that are not captured by the poststratification variables, but for which there are also differences between mobile phone owners and non-owners.

CONCLUSIONS

Mobile phone surveys need to collect data on sociodemographic background characteristics to be able to weight and adjust mortality estimates ex post facto. Fertility estimates from mobile phone surveys will be biased unless further research uncovers the mechanisms driving the bias.

Dentists' Perspective on the Impact of COVID-19 on the Utilization of Emergency Dental Services in Kuwait: A Cross-Sectional Study

This cross-sectional study intends to evaluate dentists' perceptions of COVID-19's effects on the use of emergency dental care both during and after Kuwait's lockdown periods. A convenience sample of dentists employed by the Ministry of Health's various emergency dental clinics and School Oral Health Programs (SOHP) throughout Kuwait's six governorates were invited to take part in this study. To determine the impact of various demographic and occupational characteristics on the mean perception score of the dentist, a multi-variable model was developed. The study was conducted between June-September 2021, and a total of 268 dentists (61% males and 39% females) participated in this study. When compared to pre-lockdown periods, the overall number of patients seen by dentists had significantly decreased after the lockdown period. After lockdown, there were significantly more cases of acute pulpitis with apical periodontitis, abscesses, and pericoronitis than there were before lockdown (p < 0.05). After the lockdown, a significantly higher percentage of dentists (p < 0.05) reported using fewer droplets-generating procedures to manage patients with dental emergencies. After correcting for the other variables in the model, female dentists (β = 0.146; 95% CI = 0.071 to 1.451) and non-Kuwaiti dentist (β = 0.012; 95% CI = 0.234 to 1.854) had a significantly (p < 0.05) more positive perception of the utilization of dental services than others after adjusting for the other variables in the model. The majority of dentists perceive that the COVID-19 pandemic has had a negative impact on Kuwait's use of emergency dental services.

Use of interviewer-administered telephone surveys during infectious disease outbreaks, epidemics and pandemics: a scoping review

INTRODUCTION

During the COVID-19 crisis, researchers had to collect data remotely. Telephone surveys and interviews can quickly gather data from a distance without heavy expense. Although interviewer-administered telephone surveys (IATS) can accommodate the needs of international public health research, the literature on their use during infectious disease outbreaks is scarce. This scoping review aimed to map the characteristics of IATS during infectious disease outbreaks.

METHODS

IATS conducted principally during infectious disease outbreaks and answered by informants at least 18 years old were searched from PubMed and EBSCO. There was a manual addition of relevant documents identified during an initial search. Overall trends were reported using different groupings, including WHO regions, and study details were compared before and during the COVID-19 pandemic.

RESULTS

70 IATS published between 2003 and 2022 were identified. 57.1% were conducted during the COVID-19 pandemic. Among 30 IATS conducted before the COVID-19 pandemic in the world, only 3.3% were carried out in low-income and middle-income countries (LMICs). This percentage of studies in LMICs out of all the IATS rose to 32.5% during the pandemic. The share of qualitative studies grew from 6.7% before the COVID-19 outbreak to 32.5% during the outbreak. IATS performed during the COVID-19 pandemic focused on more diverse, specific population groups, such as patients and healthcare professionals. Mobile phones are increasingly used for IATS over time.

CONCLUSION

IATS are used globally with high frequency in the Western Pacific Region and high-income countries. Technical and financial challenges continue to exist, and assessments of inclusiveness and representativeness should be carefully conducted. A lack of details related to methods was observed, and this scoping review urges researchers using this data collection method in the future to specify how they executed IATS for better use and more efficient deployment.

Implementation and outcomes of a comprehensive emergency care curriculum at a low-resource referral hospital in Liberia: A novel approach to application of the WHO Basic Emergency Care toolkit

BACKGROUND

Emergency care is vital in low- and middle-income countries (LMICs) but many frontline healthcare workers in low-resource settings have no formal training in emergency care. To address this gap, the World Health Organization (WHO) developed Basic Emergency Care (BEC): Approach to the acutely ill and injured, a multi-day, open-source course for healthcare workers in low-resource settings. Building on the BEC foundation, this study uses an implementation science (IS) lens to develop, implement, and evaluate a comprehensive emergency care curriculum in a single emergency facility in Liberia.

METHODS

A six-month emergency care curriculum consisting of BEC content, standardized WHO clinical documentation forms, African Federation of Emergency Medicine (AFEM) didactics, and clinical mentorship by visiting emergency medicine (EM) faculty was designed and implemented using IS frameworks at Redemption Hospital, a low-resource public referral hospital in Monrovia, the capital of Liberia. Healthcare worker performance on validated knowledge-based exams during pre- and post-intervention testing, post-course surveys, and patient outcomes were used to evaluate the program.

RESULTS

Nine visiting EM physicians provided 1400 hours of clinical mentorship and 560 hours of didactic training to fifty-six Redemption Hospital staff over six-months. Median test scores improved 20.0% (p<0.001) among the forty-three healthcare workers who took both the pre- and post-intervention tests. Participants reported increased confidence in caring for medical and trauma patients and comfort performing emergency care tasks on post-course surveys. Emergency unit (EU)/Isolation unit (IU) mortality decreased during the six-month implementation period, albeit non-significantly. Course satisfaction was high across multiple domains.

DISCUSSION

This study builds on prior research supporting WHO efforts to improve emergency care globally. BEC implementation over a six-month timeframe using IS principles is an effective alternative strategy for facilities in resource-constrained environments wishing to strengthen emergency care delivery.

Collecting mortality data via mobile phone surveys: A non-inferiority randomized trial in Malawi

Despite the urgent need for timely mortality data in low-income and lower-middle-income countries, mobile phone surveys rarely include questions about recent deaths. Such questions might a) be too sensitive, b) take too long to ask and/or c) generate unreliable data. We assessed the feasibility of mortality data collection using mobile phone surveys in Malawi. We conducted a non-inferiority trial among a random sample of mobile phone users. Participants were allocated to an interview about their recent economic activity or recent deaths in their family. In the group that was asked mortality-related questions, half of the respondents completed an abridged questionnaire, focused on information necessary to calculate recent mortality rates, whereas the other half completed an extended questionnaire that also included questions about symptoms and healthcare. The primary trial outcome was the cooperation rate, i.e., the number of completed interviews divided by the number of mobile subscribers invited to participate. Secondary outcomes included self-reports of negative feelings and stated intentions to participate in future interviews. We called more than 7,000 unique numbers and reached 3,054 mobile subscribers. In total, 1,683 mobile users were invited to participate. The difference in cooperation rates between those asked to complete a mortality-related interview and those asked to answer questions about economic activity was 0.9 percentage points (95% CI = -2.3, 4.1), which satisfied the non-inferiority criterion. The mortality questionnaire was non-inferior to the economic questionnaire on all secondary outcomes. Collecting mortality data required 2 to 4 additional minutes per reported death, depending on the inclusion of questions about symptoms and healthcare. More than half of recent deaths elicited during mobile phone interviews had not been registered with the National Registration Bureau. Including mortality-related questions in mobile phone surveys is feasible. It might help strengthen the surveillance of mortality in countries with deficient civil registration systems.

Role of Newly Introduced Teledentistry Service in the Management of Dental Emergencies During COVID-19 Pandemic in Qatar: A Cross-Sectional Analysis

Introduction: The lockdown imposed by the COVID-19 pandemic rendered teledentistry (TD) necessary to maintain the continuity of oral health services and avoid missing emergency dental conditions, while minimizing face-to-face visits. Our objective was to evaluate the ability of a newly introduced triage-based TD service to deliver its goals, by evaluating its processes and outcomes and assessing the demand for TD. Methods: This cross-sectional report assessed the triage processes and outcomes (triage category, referral to emergency/dental facility undertaken, remote medications prescribed, and procedures performed at the point of referral); and evaluated the demand for the newly introduced TD service during 5 months of the first wave of the pandemic. Results: Of 850 calls, about 70.6% of the samples were managed remotely; 29.4% were categorized as emergency/urgent and referred to the emergency/dental facility. Compared with other complaints, orofacial dental pain was the most common reason for the calls (41.6%, p < 0.0001). About 14.71% of callers received prescription for medications remotely. The most demanded disciplines were general dentistry, orthodontics, and oral surgery, respectively (p < 0.0001). Of those referred to a dental facility, 31.84% required no clinical intervention, 28.7% received orthodontic appliance repair, and 14.3% and 11.2% had urgent dental extractions or root canal treatments. Demand on the service fluctuated through various distinct stages of the lockdown. Conclusions: There has been continuous demand for the newly introduced TD service throughout the period of the current report despite the fluctuations, with most complaints managed remotely. TD was effective and suitable for triage, service delivery, and care during the pandemic.

Mobile technology: A tool for healthcare and a boon in pandemic

Healthcare systems deal with disease prevention, early detection, diagnosis, investigation, and timely, affordable, and safe treatment. For the delivery of services in the health sector, communication is the key to linking the service provider and the patients. Mobile technology in the recent past has rendered various platforms of communications for the healthcare system. Thus, in health, mobile technology has greatly contributed to time management and cost reduction for healthcare at every level including hospital visits to individual appointments with doctors, hence the convenience. With advancements in mobile technologies and the growing number of mobile users, newer opportunities have opened up for the use of mobiles for patient care. Emerging information and communication technologies with the help of the Internet of Things (IoT) have been instrumental in integrating different domains of the health sector with mobile technology. Thus, the technology may have the potential to become powerful medical tools to support the health sector at all levels of care. In this review, the concept, applications, and advantages of mobile technology for health and the present pandemic have been discussed. It also discusses mobile health technology, as a support system for convenient and safer healthcare for public health, and the opportunities to improve its applications for unseen future health crises.

Participatory surveillance of COVID-19 in Lesotho via weekly calls: Protocol for cell phone data collection

Background

The increase in cell phone ownership in low- and middle-income countries (LMIC) has created an opportunity for low-cost, rapid data collection by calling participants on their cell phones. Cell phones can be mobilized for a myriad of data collection purposes, including surveillance. In LMIC, cell phone–based surveillance has been used to track Ebola, measles, acute flaccid paralysis, and diarrheal disease, as well as noncommunicable diseases. Phone-based surveillance in LMIC is a particularly pertinent, burgeoning approach in the context of the COVID-19 pandemic. Participatory surveillance via cell phone could allow governments to assess burden of disease and complements existing surveillance systems.

Objective

We describe the protocol for the LeCellPHIA (Lesotho Cell Phone PHIA) project, a cell phone surveillance system that collects weekly population-based data on influenza-like illness (ILI) in Lesotho by calling a representative sample of a recent face-to-face survey.

Methods

We established a phone-based surveillance system to collect ILI symptoms from approximately 1700 participants who had participated in a recent face-to-face survey in Lesotho, the Population-based HIV Impact Assessment (PHIA) Survey. Of the 15,267 PHIA participants who were over 18 years old, 11,975 (78.44%) consented to future research and provided a valid phone number. We followed the PHIA sample design and included 342 primary sampling units from 10 districts. We randomly selected 5 households from each primary sampling unit that had an eligible participant and sampled 1 person per household. We oversampled the elderly, as they are more likely to be affected by COVID-19. A 3-day Zoom training was conducted in June 2020 to train LeCellPHIA interviewers.

Results

The surveillance system launched July 1, 2020, beginning with a 2-week enrollment period followed by weekly calls that will continue until September 30, 2022. Of the 11,975 phone numbers that were in the sample frame, 3020 were sampled, and 1778 were enrolled.

Conclusions

The surveillance system will track COVID-19 in a resource-limited setting. The novel approach of a weekly cell phone–based surveillance system can be used to track other health outcomes, and this protocol provides information about how to implement such a system.

Design and Field Methods of the ARISE Network COVID-19 Rapid Monitoring Survey

The coronavirus disease 2019 (COVID-19) pandemic has significant health and economic ramifications across sub-Saharan Africa (SSA). Data regarding its far-reaching impacts are severely lacking, thereby hindering the development of evidence-based strategies to mitigate its direct and indirect health consequences. To address this need, the Africa Research, Implementation Science, and Education (ARISE) Network established a mobile survey platform in SSA to generate longitudinal data regarding knowledge, attitudes, and practices (KAP) related to COVID-19 prevention and management and to evaluate the impact of COVID-19 on health and socioeconomic domains. We conducted a baseline survey of 900 healthcare workers, 1,795 adolescents 10 to 19 years of age, and 1,797 adults 20 years or older at six urban and rural sites in Burkina Faso, Ethiopia, and Nigeria. Households were selected using sampling frames of existing Health and Demographic Surveillance Systems or national surveys when possible. Healthcare providers in urban areas were sampled using lists from professional associations. Data were collected through computer-assisted telephone interviews from July to November 2020. Consenting participants responded to surveys assessing KAP and the impact of the pandemic on nutrition, food security, healthcare access and utilization, lifestyle, and mental health. We found that mobile telephone surveys can be a rapid and reliable strategy for data collection during emergencies, but challenges exist with response rates. Maintaining accurate databases of telephone numbers and conducting brief baseline in-person visits can improve response rates. The challenges and lessons learned from this effort can inform future survey efforts during COVID-19 and other emergencies, as well as remote data collection in SSA in general.

Social determinants of seeking emergency and routine dental care in Saudi Arabia during the COVID-19 pandemic

Background

Between March and June 2020, closing dental clinics during the COVID-19 pandemic except for emergency dental care was recommended. It is documented that health-seeking behaviors change during pandemics. The objective of this study was to examine social determinants associated with decisions to seek dental care in Saudi Arabia during the COVID-19 pandemic.

Methods

A total of 4372 participants were invited to this cross-sectional web-based survey distributed from April 21 to June 20, 2020. The survey included a list of emergency, urgent, and routine dental procedures. Participants were asked if they would seek dental care for these conditions during the pandemic, and what pain severity would make them seek dental treatment. Logistic regression models were performed for predicting variables that explain the decision to go or not to go to the dental clinic during the pandemic for each dental condition.

Results

A total of 3443 responded to this survey. The emergency dental situation participants were most willing to go to the dental clinic for was trauma involving facial bones compromising the airway (94.5%). Only 65.8% were willing to seek care for facial cellulitis compromising the airway. On average 35.2% reported seeking teleconsultation as the first step. Eighteen percent of participants were still willing to go to the dental clinic during the pandemic for routine dental procedures. Multiple logistic regression showed that females (Odds Ratio (OR): 1.6, OR 95% CI 1.3, 1.9), people who had never visited a dentist (OR: 1.8, OR 95% CI 1.3, 2.5), and people living in metropolitan regions (OR: 1.8, OR 95%: 1.4, 2.3) had higher odds for not seeking emergency dental care during this pandemic. The pain threshold for seeking dental care during the pandemic was 7 out of 10. Female, those who never visited a dentist, and those from urban regions reported higher pain threshold before seeking dental care (P value < 0.001).

Conclusion

Social disparities were found in emergency dental care seeking decision-making in Saudi Arabia during the COVID-19 pandemic. It was alarming that some people were afraid to seek dental care for life-threatening dental emergencies as cellulitis during this pandemic. This reflects the importance of increasing public health awareness and governmental regulations.

A telephone based assessment of the health situation in the far north region of Cameroon

BACKGROUND

In 2017, Field access was considerably limited in the Far North region of Cameroon due to the conflict. Médecins Sans Frontieres (MSF) in collaboration with Ministry of health needed to estimate the health situation of the populations living in two of the most affected departments of the region: Logone-et-Chari and Mayo-Sava.

METHODS

Access to health care and mortality rates were estimated through cell phone interviews, in 30 villages (clusters) in each department. Local Community Health Workers (CHWs) previously collected all household phone numbers in the selected villages and nineteen were randomly selected from each of them. In order to compare telephone interviews to face-to-face interviews for estimating health care access, and mortality rates, both methods were conducted in parallel in the town of Mora in the mayo Sava department. Access to food was assessed through push messages sent by the three main mobile network operators in Cameroon. Additionally, all identified legal health care facilities in the area were interviewed by phone to estimate attendance and services offered before the conflict and at the date of the survey.

RESULTS

Of a total of 3423 households called 43% were reached. Over 600,000 push messages sent and only 2255 were returned. We called 43 health facilities and reached 34 of them. In The town of Mora, telephone interviews showed a Crude Mortality Rate (CMR) at 0.30 (CI 95%: 0.16-0.43) death per 10,000-person per day and home visits showed a CMR at 0.16 (0.05-0.27), most other indicators showed comparable results except household composition (more Internally Displaced Persons by telephone). Phone interviews showed a CMR at 0.63 (0.29-0.97) death per 10,000-person per day in Logone-et-Chari, and 0.30 (0.07-0.50) per 10,000-person per day in Mayo-Sava. Among 86 deaths, 13 were attributed to violence (15%), with terrorist attacks being explicitly mentioned for seven deaths. Among 29 health centres, 5 reported being attacked and vandalized; 3 remained temporally closed; Only 4 reported not being affected.

CONCLUSION

Telephone interviews are feasible in areas with limited access, although special attention should be paid to the initial collection of phone numbers. The use of text messages to collect data was not satisfactory is not recommended for this purpose. Mortality in Logone-et-Chari and Mayo-Sava was under critical humanitarian thresholds although a considerable number of deaths were directly related to the conflict.

Effectiveness of SMS messaging for diarrhoea measurement: a factorial cross-over randomised controlled trial

BACKGROUND

Text messaging systems are used to collect data on symptom prevalence. Using a text messaging system, we evaluated the effects of question load, question frequency, and financial incentive on response rates and reported infant diarrhoea rates in an infant diarrhoea survey.

METHODS

We performed a factorial cross-over randomised controlled trial of an SMS surveying system for infant diarrhoea surveillance with treatments: financial incentive (yes/no), question load (1-question/3-question), and questioning frequency (daily/fortnightly). Participants progressed through all treatment combinations over eight two-week rounds. Data were analysed using multivariable logistic regressions to determine the impacts of the treatments on the response rates and reported diarrhoea rates. Attitudes were explored through qualitative interviews.

RESULTS

For the 141 participants, the mean response rate was 47%. In terms of percentage point differences (ppd), daily questioning was associated with a lower response rate than fortnightly (- 1·2[95%CI:-4·9,2·5]); high (3-question) question loads were associated with a lower response rate than low (1-question) question loads (- 7·0[95%CI:- 10·8,-3·1]); and financial incentivisation was associated with a higher response rate than no financial incentivisation (6·4[95%CI:2·6,10·2]). The mean two-week diarrhoea rate was 36·4%. Daily questioning was associated with a higher reported diarrhoea rate than fortnightly (29·9[95%CI:22·8,36·9]); with little evidence for impact by incentivisation or question load.

CONCLUSIONS

Close to half of all participants responded to the SMS survey. Daily questioning evoked a statistically higher rate of reported diarrhoea, while financial incentivisation and low (1-question) question loads evoked higher response rates than no incentive and high (3-question) question loads respectively.

TRIAL REGISTRATION

The protocol was prospectively registered on ISRCTN on the 20th of March 2019 under number ISRCTN11410773 .

A Review of Mobile Health Applications in Epidemic and Pandemic Outbreaks: Lessons Learned for COVID-19

Context: Using smart mobile devices, called mobile health (mHealth), facilitates providing health services, speeds up the process, and reduces the costs and complications of direct services. Also, mHealth has many capabilities and applications in epidemic and pandemic outbreaks. This study aimed to identify mHealth applications in epidemic/pandemic outbreaks and provide some suggestions for tackling COVID-19. Methods: To find the relevant studies, searches were done in PubMed and Scopus by related keywords during 2014 - 2020 (March 10). After selecting the studies based on the inclusion and exclusion criteria, data were collected by a data-gathering form. Results: Of the 727 retrieved studies, 17 studies were included. All studies emphasized the positive effect of mHealth for use in epidemic/pandemic outbreaks. The main applications of mHealth for epidemic/pandemic outbreaks included public health aspects, data management, educational programs, diagnosis, and treatment. Conclusions: mHealth is an appropriate method for encountering epidemic/pandemic outbreaks due to its extensive applications. In the pandemic outbreak of COVID-19, mHealth is one of the best choices to use in the patient-physician relationship as tele-visits, using in fever coach, providing real-time information for healthcare providers, population monitoring, and detecting the disease based on obtained data from different locations.

Precision Global Health - The case of Ebola: a scoping review

BACKGROUND

The 2014-2016 Ebola outbreak across West Africa was devastating, acting not only as a wake-up call for the global health community, but also as a catalyst for innovative change and global action. Improved infectious disease monitoring is the stepping-stone toward better disease prevention and control efforts, and recent research has revealed the potential of digital technologies to transform the field of global health. This scoping review aimed to identify which digital technologies may improve disease prevention and control, with regard to the 2014-2016 Ebola outbreak in West Africa.

METHODS

A search was conducted on PubMed, EBSCOhost and Web of Science, with search dates ranging from 2013 (01/01/2013) - 2017 (13/06/2017). Data was extracted into a summative table and data synthesized through grouping digital technology domains, using narrative and graphical methods.

FINDINGS

The scoping review identified 82 full-text articles, and revealed big data (48%, n = 39) and modeling (26%, n = 21) technologies to be the most utilized within the Ebola outbreak. Digital technologies were mainly used for surveillance purposes (90%, n = 74), and key challenges were related to scalability and misinformation from social media platforms.

INTERPRETATION

Digital technologies demonstrated their potential during the Ebola outbreak through: more rapid diagnostics, more precise predictions and estimations, increased knowledge transfer, and raising situational awareness through mHealth and social media platforms such as Twitter and Weibo. However, better integration into both citizen and health professionals' communities is necessary to maximise the potential of digital technologies.

Utilization of non-Ebola health care services during Ebola outbreaks: a systematic review and meta-analysis

Background

Beyond their direct effects on mortality, outbreaks of Ebola Virus Disease (EVD) might disrupt the provision of health care services in affected countries, possibly resulting in an increase in the number of deaths from non-EVD causes. We conducted a systematic review and meta-analysis of studies documenting the impact of EVD outbreaks on health care utilization.

Methods

We searched PubMed, Embase, Scopus, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Global Health, Pascal and grey literature to identify observational studies that compared indicators of health care utilization before and during the outbreak. We identified 14 752 unique citations, 22 of which met inclusion criteria. All were related to the 2013-2016 West African EVD outbreak. From the 22 studies, we extracted 235 estimates of the relative change in health care utilization during the EVD outbreak. We used multivariate regression to estimate the average effect of the outbreak on health care utilization, and to assess heterogeneity across study characteristics.

Findings

On average, health care utilization declined by 18.0% during the outbreak (95% Confidence Interval: -26.5%, -9.5%). The observed declines in health care utilization were largest in settings affected by higher levels of EVD incidence (>2.5 cases per 100 000 per week) whereas utilization did not change in settings with EVD incidence less than 0.5 cases per 100 000 per week. Declines in utilization were greater for inpatient care and for deliveries than for outpatient care. They were also larger in studies based on small samples of health facilities, suggestive of publication bias. However, several studies based on larger samples of facilities also observed declines in health care utilization.

Conclusions

During the West African EVD outbreak, the utilization of health services declined significantly. During outbreaks of EVD, attention needs to be paid to the disruption of the health services, which can have large indirect health impacts.

Knockdown and recovery of malaria diagnosis and treatment in Liberia during and after the 2014 Ebola outbreak

Setting: The malaria-endemic country of Liberia, before, during and after the 2014 Ebola outbreak. Objective: To describe the consequences of the Ebola outbreak on Liberia's National Malaria Programme and its post-Ebola recovery. Design: A retrospective cross-sectional study using routine countrywide programme data. Results: Malaria caseloads decreased by 47% during the Ebola outbreak and by 11% after, compared to the pre-Ebola period. In those counties most affected by Ebola, a caseload reduction of >20% was sustained for 12 consecutive months, while this lasted for only 4 consecutive months in the counties least affected by Ebola. Linear regression of monthly proportions of confirmed malaria cases-as a proxy indicator of programme performance-over the pre- and post-Ebola periods indicated that the malaria programme could require 26 months after the end of the acute phase of the Ebola outbreak to recover to pre-Ebola levels. Conclusions: The differential persistence of reduced caseloads in the least- and most-affected counties, all of which experienced similar emergency measures, suggest that factors other than Ebola-related security measures played a key role in the programme's reduced performance. Clear guidance on when to abandon the emergency measures after an outbreak may be needed to ensure faster recovery of malaria programme performance.
