RESUMO

BACKGROUND AND OBJECTIVES: Early experience with Cepheid Xpert® HPV assay (Xpert® HPV) suggests that its quick turnaround time and ease of application might make it a relevant contender for routine use in low and middle income countries (LMICs). In the context of a cervical screening service in rural Malawi, we aimed to assess practicalities of local laboratory testing with Xpert® HPV and provide preliminary high-risk HPV (HR-HPV) prevalence data. STUDY DESIGN: Liquid-based cytology (LBC) specimens were collected from women attending cervical screening clinics in Nkhoma, Malawi. Xpert® HPV testing was carried out according to manufacturer's instructions. Partial genotyping results were obtained immediately (HPV 16, 18/45 and HR-HPV 'other'). Review of individual channel data provided further breakdown of other HR-HPV types into HPV 31 and related; HPV 51/59 and HPV 39 and related. RESULTS: Valid HR-HPV results were obtained from 750/763 samples. Most samples were from previously unscreened women, with 92.3% aged between 20 and 60 years. Overall HR-HPV positivity was 19.9%, with HR-HPV 'other' being more than twice as frequent as HPV 16 or HPV 18/45 and HPV 31-related (HPV 31, 33, 35, 52 or 58) most prevalent. Known HIV status was low (7.3%), but HR-HPV positivity in this group was much higher (43.4%). CONCLUSIONS: HR-HPV testing using Xpert® HPV was practical in a small rural laboratory. The rapid turnaround (within 2h) could facilitate a 'see and treat' programme. Partial genotyping allows assessment of risk beyond HPV 16/18. The high prevalence of HPV 31 and related types warrants further investigation.

RESUMO

The incidence of cervical cancer in Malawi is the highest in the world and projected to increase in the absence of interventions. Although government policy supports screening using visual inspection with acetic acid (VIA), screening provision is limited due to lack of infrastructure, trained personnel, and the cost and availability of gas for cryotherapy. Recently, thermo-coagulation has been acknowledged as a safe and acceptable procedure suitable for low-resource settings. We introduced thermo-coagulation for treatment of VIA-positive lesions as an alternative to cryotherapy within a cervical screening service based on VIA, coupled with appropriate, sustainable pathways of care for women with high-grade lesions and cancers. Detailed planning was undertaken for VIA clinics, and approvals were obtained from the Ministry of Health, Regional and Village Chiefs. Educational resources were developed. Thermo-coagulators were introduced into hospital and health centre settings, with theoretical and practical training in safe use and maintenance of equipment. A total of 7,088 previously unscreened women attended VIA clinics between October 2013 and March 2015. Screening clinics were held daily in the hospital and weekly in the health centres. Overall, VIA positivity was 6.1%. Almost 90% received same day treatment in the hospital setting, and 3- to 6-month cure rates of more than 90% are observed. Thermo-coagulation proved feasible and acceptable in this setting. Effective implementation requires comprehensive training and provider support, ongoing competency assessment, quality assurance and improvement audit. Thermo-coagulation offers an effective alternative to cryotherapy and encouraged VIA screening of many more women.

RESUMO

OBJECTIVE: To analyze maternal deaths at Nkhoma Church of Central Africa Presbyterian (CCAP) Hospital and identify factors causing delays in care. METHODS: Maternal death audits are performed after every maternal death at Nkhoma CCAP Hospital. Information regarding the care provided at the health facility, the referral process, and any delays in the community was collected by an audit team using a structured approach. Data from August 2007 to September 2011 were analyzed retrospectively. RESULTS: In total, 61 maternal deaths occurred during the study period, of which 58 were analyzed. Most deaths were categorized as indirect (n=34 [58.6%]). Non-pregnancy-related infections were the leading cause of indirect death (n=22), with meningitis the most common (n=13). Most patients experienced a delay in seeking care (n=37 [63.8%]), a transport delay (n=43 [74.1%]), or a delay in receiving adequate care (n=34 [58.6%]). CONCLUSION: Most maternal deaths had indirect causes and were associated with delays in all phases. An audit makes clear which part of the referral chain needs to be strengthened. Nkhoma CCAP Hospital has taken steps to address all phases of delay.
