Validation of Chichewa Short Musculoskeletal Function Assessment (SMFA) questionnaire: A cross-sectional study

BackgroundThe Short Musculoskeletal Function Assessment (SMFA) tool measures function and quality of life in patients with musculoskeletal conditions. ObjectiveThis study aimed to translate and adapt culturally the SMFA into Chichewa, and assess its clinimetric properties. MethodsThe translated Chichewa version was administered to 53 patients with musculoskeletal disorders. To assess repeatability, an additional 20 patients answered the questionnaire twice over a time interval of two weeks. Internal consistency, floor and ceiling effects, and repeatability were tested; construct validity was assessed with the World Health Organization Quality of Life Assessment tool (WHOQOL-BREF).ResultsThere was good internal consistency for both Dysfunction and Bothersome indices (Cronbach’s alpha 0.90) and good construct validity between both indices with the WHOQOL-BREF. Pearson’s correlation coefficient and intraclass correlation coefficient (ICC) for repeatability for the Dysfunction Index were 0.941 and 0.922 (95% CI: 0.772, 0.971) respectively, and 0.877 and 0.851 (95% CI: 0.629, 0.941) for the Bothersome Index respectively.ConclusionThe translated Chichewa SMFA is a valid tool for populations that speak the Chichewa language

Drivers’ risk profile indicates the need for a graduated driving licence in South Africa

Background. Current driver mortality estimates do not consider the great differences in exposure across the population, giving a false impression that driver deaths are lowest in the youngest age group. Interventions to reduce risk among the younger age group include graduated driver licensing (GDL) . a three-phase licensing system for novice drivers consisting of a learnerfs permit, a provisional license, and a full license.Objectives. We calculated driver fatality rates per 10 000 registereddrivers in each age group and assessed the need for stricter licensingconditions for novice and younger drivers. Methods. Age-specific driver mortality rates were calculated using Western Cape Province 2008 mortuary data. The total number of licensed drivers in each age group served as the denominator. Incidence rate ratios were calculated using the age group of 65 - 79 years as the reference. Chi-square test of trendon incidence rate ratios for the age groups was done. Statistical significance was set as p<0.05.Results. There were 339 driver deaths; mean age was 39.4}13.8 years, and males accounted for 80% of the deaths. Age-specific driver mortality rates were highest in the youngest age group (15 - 19 years). There was a significant progressive decrease (except for the age group 45 - 49 years) in the risk of death from road traffic injuries with increasing age compared with the age group .65 years (chi2 for trend p<0.0001).Conclusion. This study showed a relationship between driverfs mortality risk and younger age, and underscores the need for introduction of a GDL programme in South Africa

Avascular necrosis of the femoral head in HIV positive patients-an assessment of risk factors and early response to surgical treatment

26 consecutive patients (37 hips) with avascular necrosis (AVN) of the femoral head treated surgically at our institution from 1999 to 2008 were reviewed . The aims of the study were to evaluate the risk factors associated with AVN in HIV positive and HIV negative individuals, and assess early response to total hip replacement (THR) surgery in HIV positive and negative patients. There were 15 male and 11 female  patients in total. The mean age for all patients was 47.1± 8.0 years  (range, 33 to 66 years). 12 patients were HIV positive, 11 patients were HIV negative and 3 patients had unknown HIV status. Excessive alcohol intake was the most common risk factor for developing AVN .15 patients (58%) had more than one risk factor for AVN and only 2/12 (17%) HIV positive patients had no other risk factor apart from HIV infection. There were no early postoperative complications in 34 arthroplasties in both HIV positive and negative patients. The aetiology of AVN seems often to be multifactorial, even in the presence of HIV infection. Early response to arthroplasty surgery in AVN of the femoral head is equally good irrespective of the HIV serostatus of the patients

Geographical Differences in the Forefoot Morphology – A Comparative Radiological Study of Feet in Malawi and UK

Background: Many skeletal morphological differences between populations have been reported with possible but unproven clinical importance. This study was aimed at identifying the normal radiographic findings and measurements seen in patients from Southern Africa and compares them to a European population’s values.Methods: AP foot radiographs of 40 adults from Blantyre, Malawi were compared with those of 40 adults from London, UK. For each patient, measurements were taken of: 1st and 2nd metatarsal lengths, the 1st/2nd intermetatarsal angle, the 1st metatarso- phalangeal angle (the ‘bunion’ angle), and the 2nd metatarsal mortice joint medial and lateral depths.Results: Our results show an increased 1st/2nd metatarsal angle in Malawian feet, but a reduced ‘bunion’ angle. We also found the second metatarsal length to be longer relative to the first in the Malawian foot, and the 2nd metatarsal base to be significantly more covered by its mortice than in UK feet.Conclusion: This racial anatomical variation may convey more stability and less risk of a Lisfranc dislocation. It is also important to be aware of the normal range of these values when considering the need for forefoot arthroplasty procedures

Treatment outcomes of congenital pseudarthrosis of the tibia at Beit Cure International Hospital in Blantyre, Malawi

Background: Congenital pseudarthrosis of the tibia (CPT) is a rare condition. The natural history of CPT includes persistent instability and progressive deformity. Several CPT treatment methods have been practiced, however, in Africa where there is scarce information on the modalities of treatment available and their outcomes. Methods: A retrospective cross-sectional study which was conducted among patients with CPT at Beit Cure International Hospital (BCIH), Malawi. Forty-four patients were recruited in this study and their treatment modalities and outcomes were analyzed. Results: Out of 44 patients recruited in this study, majority (63.6%) were male. The majority of cases were stage 4 congenital tibia pseudarthrosis by Crawford classification. Most patients were treated by more than one surgical modality; however, surgical excision and intramedullary rodding was commonly used (54.7%). The outcomes of treatment were good in 5%, fair in 30%, with amputation in 45% and poor outcomes in 20% of the patients. Complications developed in 60% of patients, predominated by limb length discrepancy. The foot and ankle status were rated by Oxford Foot and Ankle scoring system (OxFAQ). Conclusions: Congenital pseudarthrosis of the tibia is a complex congenital disorder with multiple modalities of treatment. Majority of the patients were treated by more than one operation. Some patients ended up with amputation or poor outcome. Limb length discrepancy, deep infection and pin tract infection are among the common complications. Keywords: congenital pseudarthrosis; tibia; treatment outcomes; Malaw

First aid management of paediatric burn and scald injuries in Southern Malawi: a mixed methods study

Background: In sub-Saharan Africa, burn and scald injuries occur more commonly in children aged less than five years, than in any other age group, and carry a high lifetime morbidity. The optimal first aid at the time of injury includes the use of cool running water, which can reduce pain, scarring, and skin grafting. Data on the types of first aid used in Malawi is lacking, as is an in-depth understanding of the underlying factors which may influence this health behaviour. This study sought to: (a) document the types of first aid after paediatric burn and scald injuries in Southern Malawi; and (b) explore factors affecting the choice of first aid used. Methods and findings: We conducted a sequential explanatory mixed methods study. Quantitative analysis of a prospectively collected database of all patients aged less than 17 years admitted to the only burn unit in Southern Malawi was followed by thematic analysis of semi-structured interviews with 15 adults who had witnessed a paediatric burn or scald injury. 1326 patients aged less than 17 years were admitted to the Queen Elizabeth Central Hospital between July 2009 and December 2016. Median age was 3.0 years (IQR 1.9–5.0) and male to female ratio 1:0.9. The commonest cause of injury was hot liquid (45%), followed by open fire (31%) and porridge (12%). First aid was applied in 829 patients (69%), the commonest applications used were water (31%) and egg (21%). There was a statistically significant association between the type of first aid and secondary education of the father (p = 0.009) or mother (p = 0.036); however, the type of first aid used was more likely to be egg rather than water. Analysis of qualitative interviews identified four main themes: perceived roles and responsibilities within the community, drivers of individual behaviours, availability, and trust. Participants reported using eggs as a first aid treatment, as these were readily available and were seen to reduce the occurrence of blisters and prevent peeling of the skin. By comparison, there was a strong underlying fear of using water on burn injuries due to its association with peeling of the skin. Intergenerational learning appeared to play a strong role in influencing what is used at the time of injury, and mothers were the key source of this information. Conclusions: This study provides the largest description of first aid use in sub-Saharan Africa, strengthening the evidence that remedies aside from water are commonly used and that higher parental education levels do not translate to increased use of water, but rather use of alternative treatments. Our qualitative findings allow improved understanding of how first aid for paediatric burns is perceived in rural Malawi communities, providing insight as to why certain first aid choices are made and the possible barriers and facilitators to the adoption of water as a first aid treatment

An Assessment of Open Fracture Management in Hospitals in Malawi Before and Immediately After Implementing Open Fracture Guidelines.

Background Open fractures, a common consequence of road traffic collisions, are associated with a high risk of complications. The introduction of standard guidelines has been shown to improve patient care and reduce the risk of complications in several countries. In September 2021, the Malawi Orthopaedic Association/Arbeitsgemeinschaft für Osteosynthesefragen Alliance (MOA/AOA) guidelines and standards for open fracture management were introduced in Malawi. This study aimed to assess the management of open fractures in hospitals in Malawi, before and after implementing a training course on the MOA/AOA open fracture guidelines. Methods This was a descriptive and quantitative, before-and-after study that reviewed the medical files of patients with open fractures at Zomba Central Hospital and Mulanje, Salima, and Mangochi district hospitals over two 3-month periods. Variables included initial assessment; antibiotic prophylaxis; place of debridement; type of anesthesia; treatment of the open fracture in the emergency department, operating room, and wards; and short-term complications requiring hospital treatment. Results A total of 88 open-fracture case files were reviewed; 43 were prior and 45 were subsequent to the implementation of the open fracture guidelines. The overall median patient age was 36 years (interquartile range, 27 to 45 years), and 91% (80) were male. Limb neurovascular status assessment and documentation improved from 26% (11) of the patients before the guidelines to 62% (28) afterward (p = 0.0002). The percentage who underwent debridement in the operating room significantly increased from 19% (8) to 69% (31) (p = 0.01). The percentage who underwent debridement under general or spinal anesthesia significantly increased from 5% (2) to 38% (17) and from 12% (5) to 29% (13), respectively (p= 0.001). The wound infection rate decreased from 21% to 11%, but this was not significant, and there was no change in the overall complication rate (p = 0.152). Conclusions This study suggests that training on the MOA/AOA open fracture management guidelines followed by their implementation can lead to at least temporary improvement in the management of open fractures. Nevertheless, additional studies need to be performed to understand the effect on long-term patient outcomes. Levels of evidence Therapeutic Level III.
