The developing world of pre-operative optimisation: a systematic review of Cochrane reviews

Pre-operative optimisation is a heterogenous group of interventions aimed at improving peri-operative outcomes. To understand the evidence for pre-operative optimisation in the developing world, we systematically reviewed Cochrane reviews on the topic according to the Human Developmental Index (HDI) of the country where patient recruitment occurred. We used summary statistics and cartograms to describe the HDI, year of publication, timing of pre-operative intervention and risk of bias associated with each included trial. We assessed the impact of multinational trials on the risk of bias introduced by countries of differing HDI. Four-hundred and nine trials representing 51 countries and 89,389 randomly allocated participants were summarised in this review. Four-hundred and nineteen out of 451 (93%) trial populations (i.e. a group of study participants from one country) were from high and very high HDI countries. The median (IQR [range]) HDI of countries were 0.862 (0.806–0.892 [0.445–0.949]). Three of the 409 included trials were multinational, representing 32 countries and 37,736 out of 89,389 (42.2%) included participants. Africa was the least represented continent, with only 4 included trials and 566 participants, of which 62.3% were from one multinational trial. The overall risk of bias was high or unclear in 381 out of 409 (93%) trials. Inclusion of multinational trials decreased the proportion of trial populations introducing high or unclear risk of bias by 9.4% (95%CI 5.1–13.7; p < 0.0001). Half of the world's population live in low- and middle-HDI countries. This population is poorly represented in systematically reviewed evidence on pre-operative optimisation. Multinational trials increase the knowledge contribution from low- and middle-HDI countries and decrease risk of bias in systematic reviews.     

Surviving a stroke in South Africa: outcomes of home-based care in a low-resource rural setting

Background: Little is known of stroke outcomes in low- and middle-income countries with limited formal stroke rehabilitation services and of homebased-stroke services delivered within the primary health care (PHC) context by community health workers (CHWs).

Objectives: To describe and analyze the outcomes of patients with stroke from a rural PHC setting in the Western Cape, South Africa.

Methods: In a longitudinal survey, 93 stroke patients, referred to home and community-based care services (HCBC) between June 2015 and December 2017, were assessed at baseline, one month and three months. Changes in function (Barthel Index (BI)), caregiver strain (Caregiver Strain Index (CSI)), impact of environmental factors and satisfaction with stroke care were measured.

Results: HCBC was delayed, fragmented and brief (median session duration 20 minutes (IQR 15.0–30.0)). Although function improved significantly, dependence remained high: median BI score changed from 40.0 (IQR 15.0–70.0) to 62.5 (IQR 30.0–81.25) (p = .019). A third (33.0% (30/91)) of caregivers initially experienced strain and the median CSI score remained 3.0 (IQR 0.0–7.0) (p = .672). Overall, patient and caregiver satisfaction with HCBC was low with only 46.9% (31/66) of caregivers and 17.4% (12/69) of patients satisfied with all aspects of care. Only 47.6% of assistive product needs were met. Environmental factors negatively impacted on patient function and caregiving.

Conclusions: Clinical practice pathways and referral guidelines should be developed for the HCBC platform. Specific training of CHWs, focusing on how to educate, support and train family caregivers, provide assistive devices and refer to health services is needed.     

Preoperative Patient Education Class During an Orthopedic Mission Trip: Effects on Knowledge,Anxiety, and Informed Consent

BackgroundPatient knowledge about arthritis and risks, benefits, and outcomes of joint arthroplasty in developing countries is unknown. We evaluated the effectiveness of a preoperative class on improving knowledge and decreasing anxiety during a surgical mission trip offering total joint arthroplasty.MethodsA team of US health care providers taught a preoperative class to 41 patients selected for total joint arthroplasty during a surgical mission trip to Guyana. Participants completed a 32-point survey about arthritis; indications, risks, and benefits of joint arthroplasty; and postoperative, in-patient rehabilitation expectations. The State-Trait Anxiety Inventory was used to measure participant anxiety. Participants completed identical surveys before and after class. Matched-pairs Student t tests were used to compare means between preclass and postclass surveys. Significance was accepted at P < .05.ResultsSeventy-eight percent of patients (31 of 41) scored less than 12 of 32 possible points (40%) on the preclass knowledge questionnaire. Mean ± standard deviation knowledge scores improved from 14.0 ± 4.5 before the class to 16.5 ± 6.5 after the class (P = .008). Anxiety scores (n = 33) improved from 35 ± 13 before the class to 33 ± 12 after the class (P = .047).ConclusionOn this surgical mission trip, underserved patients' knowledge about total joint arthroplasty increased only modestly after taking a preoperative class. Greater understanding of how to educate patients and reduce their anxiety on medical missions is needed.     

Effect of a New Social Support Program by Voluntary Organization in Pediatric Oncology Department in a Developing Country

Comprehensive childhood cancer treatment in the modern era means not only strenuous treatment regimens and meticulous nursing care, it also implies attention to social, psychological, and financial aspects of disease and treatment. In a developing country like ours, though it is possible to provide good medical and nursing care in government set-up, there is always shortage of workforce and financial support, leading to nonadherence to treatment regimens by patients and parents, resulting in suboptimal treatment outcomes. Overcrowding of pediatric cancer patients along with general patients for lab tests and other hospital services, poor drug compliance, treatment abandonment, and lost to follow-up, lack of funding to meet nonmedical expenses and inadequate facility for providing psychological support were some of the major reasons we could identify as lacunas in our pediatric oncology division (POD). We introduced a new social support program with the help of additional staff supported by a nongovernmental agency, and new quality improvement services were introduced. The impact was demonstrable as reduction in waiting time in the hospital, allayed anxiety of painful procedures, better drug compliance, less treatment abandonment, and improved follow-up. This can be emulated in similar other resource-limited centers.
