Antimicrobial resistance in hospitalized surgical patients: a silently emerging public health concern in Uganda.

ABSTRACT:

Background

Surgical site infections (SSIs) are difficult to treat and are associated with substantially longer hospital stay, higher treatment cost, morbidity and mortality, particularly when the etiological agent is multidrug-resistant (MDR). To address the limited data in Uganda on SSIs, we present the spectrum of bacteria isolated from hospitalized patients, the magnitude and impact of MDR bacterial isolates among patients with SSIs.

Methods

A descriptive cross sectional study was conducted from September 2011 through April 2012 involving 314 patients with SSIs in the obstetrics & gynecology, general surgery and orthopedic wards at Mulago National Hospital in Kampala, Uganda. Wound swabs were taken and processed using standard microbiological methods. Clinico-demographic characteristics of patients were obtained using structured questionnaires and patients' files.

Results

Of the 314 enrolled patients with SSIs (mean age 29.7 ±13.14 years), 239 (76.1%) were female. More than half of the patients were from obstetrics and gynecology (62.1%, 195/314). Of 314 wound swabs taken, 68.8% (216/314) were culture positive aerobically, yielding 304 bacterial isolates; of which 23.7% (72/304) were Escherichia coli and 21.1% (64/304) were Staphylococcus aureus. More than three quarters of Enterobacteriaceae were found to be extended spectrum beta lactamase (ESBL) producers and 37.5% of S. aureus were Methicillin resistant S. aureus (MRSA). MDR occurred in 78.3% (238/304) of the isolates; these were more among Gram-negative bacteria (78.6%, 187/238) compared to Gram-positive bacteria (21.4%, 51/238), (p-value < 0.0001, ?2 = 49.219). Amikacin and imepenem for ESBL-producing Enterobacteriacea and vancomycin for MRSA showed excellent performance except that they remain expensive drugs in Uganda.

Conclusion

Most SSIs at Mulago National Hospital are due to MDR bacteria. Isolation of MRSA and ESBL-producing Enterobacteriaceae in higher proportions than previously reported calls for laboratory guided SSIs- therapy and strengthening of infection control surveillance in this setting.

Project description:BackgroundAcute disease outbreaks such as the COVID-19 pandemic cause a high burden of psychological distress in people worldwide. Interventions to enable people to better cope with such distress should be based on the best available evidence. We therefore performed a scoping review to systematically identify and summarize the available literature of interventions that target the distress of people in the face of highly contagious disease outbreaks.MethodsMEDLINE, Cochrane CENTRAL, Web of Science (January 2000 to May 7, 2020), and reference lists were systematically searched and screened by two independent reviewers. Quantitative and qualitative studies investigating the effects of psychological interventions before, during, and after outbreaks of highly contagious emerging infectious diseases, such as SARS, MERS, Ebola, or COVID-19 were included. Study effects were grouped (e.g. for healthcare professionals, community members, people at risk) and intervention contents at the individual and organizational level summarized. We assessed the level of evidence using a modified scheme from the Oxford Centre for Evidence-based Medicine and the Australian National Health and Medical Research Council.ResultsOf 4030 records found, 19 studies were included (two RCTs). Most interventions were delivered during-exposure and face-to-face, focused on healthcare workers and crisis personnel, and combined psychoeducation with training of coping strategies. Based on two high-quality studies, beneficial effects were reported for resilience factors (e.g. positive cognitive appraisal) and professional attitudes of healthcare workers, with mixed findings for mental health (e.g. depression). Across all studies, there was positive qualitative feedback from participants and facilitators. We identified seven ongoing studies mostly using online- and mobile-based deliveries.ConclusionsThere is preliminary evidence for beneficial effects of interventions to enable people to better cope with the distress of highly contagious emerging disease outbreaks. Besides the need for more high-quality studies, the summarized evidence may inform decision makers to plan interventions during the current pandemic and to develop pandemic preparedness plans.

Project description:IntroductionSexual harassment is a ubiquitous problem that prevents women's integration and retention in the workforce. Its prevalence had been documented in previous health sector studies in Uganda, indicating that it affected staffing shortages and absenteeism but was largely unreported. To respond, the Ministry of Health needed in-depth information on its employees' experiences of sexual harassment and non-reporting.MethodsOriginal descriptive research was conducted in 2017 to identify the nature, contributors, dynamics and consequences of sexual harassment in public health sector workplaces and assess these in relation to available theories. Multiple qualitative techniques were employed to describe experiences of workplace sexual harassment in health employees' own voices. Initial data collection involved document reviews to understand the policy environment, same-sex focus group discussions, key informant interviews and baseline documentation. A second phase included mixed-sex focus group discussions, in-depth interviews and follow up key informant interviews to deepen and confirm understandings.ResultsA pattern emerged of men in higher-status positions abusing power to coerce sex from female employees throughout the employment cycle. Rewards and sanctions were levied through informal management/ supervision practices requiring compliance with sexual demands or work-related reprisals for refusal. Abuse of organizational power reinforced vertical segregation, impeded women's productive work and abridged their professional opportunities. Unwanted sexual attention including non-consensual touching, bullying and objectification added to distress. Gender harassment which included verbal abuse, insults and intimidation, with real or threatened retaliation, victim-blaming and gaslighting in the absence of organizational regulatory mechanisms all suppressed reporting. Sexual harassment and abuse of patients by employees emerged inadvertently.Discussion/conclusionsSex-based harassment was pervasive in Ugandan public health workplaces, corrupted management practices, silenced reporting and undermined the achievement of human resources goals, possibilities overlooked in technical discussions of support supervision and performance management. Harassment of both health system patients and employees appeared normative and similar to "sextortion." The mutually reinforcing intersections of sex-based harassment and vertical occupational segregation are related obstacles experienced by women seeking leadership positions. Health systems leaders should seek organizational and sectoral solutions to end sex-based harassment and make gender equality a human resource for health policy priority.
