The participation of people with multiple health conditions is insufficiently represented in clinical trials. Treatment recommendations remain ambiguous in the absence of substantial empirical assessments of comorbidity's influence on treatment effects. Our strategy involved producing estimates of how comorbidity affects treatment outcomes, using individual participant data (IPD).
Across 22 index conditions, 120 industry-sponsored phase 3/4 trials provided us with IPD data for a total of 128,331 individuals. Registration of trials between 1990 and 2017 was contingent on having accrued at least 300 participants. The trials included in the study were both multicenter and international in scope. We scrutinized the most commonly reported outcome in the included trials for each index condition. To assess the impact of comorbidity on treatment effectiveness, we undertook a two-stage individual participant data (IPD) meta-analysis. For each trial, we modeled the interaction between comorbidity and treatment arm, adjusting for age and sex. For every index condition and corresponding treatment, we meta-analyzed the interaction terms linking comorbidity to treatment, pooling the results across all included trials. necrobiosis lipoidica We estimated the impact of comorbidity by using three approaches: (i) counting the number of comorbidities, beyond the index condition; (ii) categorising the presence or absence of six common comorbid diseases for each index condition; and (iii) utilizing continuous indicators, including the estimated glomerular filtration rate (eGFR). The models for treatment effects employed the usual measurement system for that outcome type: absolute for numerical data, and relative for dichotomous outcomes. Participants' mean ages in the trials, fluctuating from 371 (allergic rhinitis) to 730 (dementia), corresponded with the variability in male participant percentages, which ranged from 44% (osteoporosis) to 100% (benign prostatic hypertrophy). Allergic rhinitis trials demonstrated a comorbidity rate of 23% for participants with three or more comorbidities, while systemic lupus erythematosus trials showed a markedly higher rate, reaching 57%. Our evaluation of three measures of comorbidity showed no impact on the efficacy of the treatment. 20 conditions saw the continuous outcome variable in action (like adjustments in glycosylated hemoglobin levels in diabetics), and 3 conditions exhibited discrete outcomes (such as the frequency of headaches in migraine). This pattern was consistent in each case. While all results indicated no significant effect, the precision of estimating treatment effect modifications differed. For instance, sodium-glucose co-transporter-2 (SGLT2) inhibitors in type 2 diabetes (interaction term comorbidity count 0004) displayed a precise estimate, with a 95% CI of -0.001 to 0.002. Conversely, the treatment interaction between corticosteroids and asthma (interaction term -0.022) had wider credible intervals, extending from -0.107 to 0.054. Wang’s internal medicine A major shortcoming of these studies was their failure to be specifically configured or powered to analyze variations in treatment responses according to the presence of multiple comorbidities, and a relatively small number of participants suffered from more than three co-occurring illnesses.
Rarely do assessments of treatment effect modification incorporate the variable of comorbidity. The data from the included trials showed no empirical support for a modification of the treatment effect by comorbidity. The prevalent assumption in evidence synthesis regarding efficacy is its uniformity across subgroups, a point frequently met with criticism. Our study suggests that this assumption is logical in the context of moderate comorbid conditions. Therefore, evaluating trial effectiveness alongside information on natural disease progression and competing hazards helps determine the potential overall advantage of treatments, considering co-existing conditions.
Comorbidity is typically disregarded in the analysis of treatment effect modifications. In the trials included in this analysis, the presence of comorbidity did not demonstrably influence the effectiveness of the treatment. The prevalent assumption in evidence synthesis is that efficacy remains consistent across subgroups, a supposition frequently challenged. Our research points to the plausibility of this assertion when the number of co-existing conditions is relatively low. Hence, findings from therapeutic trials can be integrated with information about the natural history of the condition and the presence of competing risks, thereby providing insight into the likely overall benefit of treatments, especially in the context of co-occurring medical conditions.

Globally, antibiotic resistance represents a public health crisis, notably in low- and middle-income countries where the financial burden of antibiotics needed for resistant infections is often too high to bear. The disproportionately high burden of bacterial diseases, especially among children, in low- and middle-income countries (LMICs) is further complicated by the jeopardizing effects of antibiotic resistance on progress in these regions. Outpatient antibiotic use plays a substantial role in driving antibiotic resistance, but data regarding inappropriate antibiotic prescribing in low- and middle-income countries remains scarce at the community level, which is where the majority of antibiotic prescriptions are administered. To characterize the inappropriate antibiotic prescribing patterns among young outpatient children in three low- and middle-income countries (LMICs), and to ascertain the factors that influence this pattern, was the aim of this work.
Our study leveraged data from the BIRDY (2012-2018) community-based, prospective cohort of mothers and children, studied across urban and rural areas in Madagascar, Senegal, and Cambodia. Beginning at their birth, children were followed up in a longitudinal study for a time span of 3 to 24 months. The data encompassing all outpatient consultations and antibiotics prescribed was logged. We classified inappropriate antibiotic prescriptions as those given for conditions not needing antibiotics, disregarding the duration, dosage, or form of the antibiotic. An algorithm, developed according to international clinical guidelines, was instrumental in the a posteriori determination of antibiotic appropriateness. A mixed-effects logistic analysis was conducted to examine the predictors of antibiotic prescriptions in consultations where antibiotics were not medically indicated for children. Over the observed follow-up period, 11762 outpatient consultations were recorded for the 2719 children examined, of which 3448 required antibiotic prescription. Of all consultations that concluded with an antibiotic prescription, a striking 765% were determined not to require the use of antibiotics, with a low of 715% seen in Madagascar and a high of 833% in Cambodia. Of the 10,416 consultations (88.6% of total), not requiring antibiotic treatment, the antibiotic prescription was surprisingly given to 2,639 (253%). The proportion in Madagascar (156%) was markedly lower than in either Cambodia (570%) or Senegal (572%), demonstrating statistical significance (p < 0.0001). Constituting a significant portion of inappropriate antibiotic prescribing in consultations not needing antibiotics, rhinopharyngitis accounted for 590% of consultations in Cambodia and 79% in Madagascar, while gastroenteritis without blood in the stool represented 616% and 246% respectively. Consultations for uncomplicated bronchiolitis in Senegal resulted in 844% of inappropriately prescribed medications. Cambodia and Madagascar witnessed amoxicillin as the dominant inappropriate antibiotic prescription, at 421% and 292% respectively. Senegal’s most frequent inappropriate prescription was cefixime, at 312%. A significant association was found between inappropriate prescription practices and patient age exceeding three months and rural living conditions. Adjusted odds ratios (aOR) varied between countries for these factors, with age-related aORs ranging from 191 (163–225) to 525 (385–715) and rural residence-related aORs from 183 (157–214) to 440 (234–828), respectively. All were statistically significant (p < 0.0001). A diagnosis assigned a higher severity score correlated with a heightened probability of an inappropriate prescription (adjusted odds ratio = 200 [175, 230] for moderate severity, 310 [247, 391] for the most severe cases, p < 0.0001), mirroring a similar association with consultations conducted during the rainy season (adjusted odds ratio = 132 [119, 147], p < 0.0001). Due to the absence of bacteriological documentation, our study faces a significant limitation. This lack could have contributed to diagnostic misclassifications and possibly an inflated rate of inappropriate antibiotic prescriptions.
This study documented a considerable amount of inappropriate antibiotic prescribing for pediatric outpatients across Madagascar, Senegal, and Cambodia. selleck inhibitor While prescription practices differed considerably between countries, we ascertained common risk factors linked to inappropriate medication prescribing. Programs at the community level for optimizing antibiotic prescribing practices are indispensable for LMICs.
The study found a considerable amount of improper antibiotic prescriptions among pediatric outpatients in Madagascar, Senegal, and Cambodia. Despite the significant diversity in prescribing practices across nations, we identified consistent risk factors for inappropriate medication prescribing. The effectiveness of local antibiotic stewardship programs in low- and middle-income communities is evident in this context.
