Non-adherence to diabetes treatment at Mulago Hospital in Uganda: prevalence and associated factors

Background

Non-adherence to diabetes treatment leads to poor glucose control and increases the risk of disease complications. The prevalence and factors associated with non-adherence in resource limited settings should be determined so as to lower the impact of a disease that is on the increase, on the health systems which are already overburdened with communicable diseases.

Objectives

To determine the prevalence and factors associated with non-adherence to diabetes treatment.

Methods

A cross sectional study was carried out from February to April 2004 in Mulago Hospital, Uganda. The participants were 402 type 1 and 2 diabetic patients selected from the outpatients'' diabetic clinic using systematic sampling. They were aged 18 years and above, had been taking diabetes treatment for at least one month and gave informed consent to participate. Non-adherence was assessed using patients'' self reports.

Results

The prevalence of non-adherence was 28.9% (n = 116, 95%CI = 24.5 – 33.3%). Factors that were independently associated with non-adherence were: female gender (OR = 2.9, 95%CI = 1.4 – 6.3), not understanding the drug regimen well (OR = 4.0, 95%CI = 1.0 – 16.3), affording only some or none of prescribed drugs (OR = 3.7, 95%CI = 1.8 – 7.6) and longer time since last since last visit to a health worker (OR = 7.3, 95%CI = 2.7 – 19.9).

Conclusions

Adherence to diabetic treatment was suboptimal. There is need to improve it through strategies helping patients understand their drug regimens, always availing drugs in the hospital so that they do not have to buy them and giving shorter time between visits to health worker. Further studies should be done to find out why females were not adhering to treatment so as to improve their adherence.     

Treatment non-adherence among patients with poorly controlled type 2 diabetes in ambulatory care settings in southwestern Nigeria

Background

Poor adherence to prescribed therapy among patients with chronic diseases is a growing concern which undermines the benefits of current medical care.

Objectives

To evaluate the pattern of treatment non-adherence among ambulatory patients with poorly controlled type 2 diabetes in southwestern Nigeria, and to determine the possible factor(s) that accounted for such non-adherence with a view to identifying areas of future intervention to improve outcome.

Methods

A prospective cross-sectional interview using the concept of RIM (Recognize, Identify and Manage) model was used to evaluate adherence to treatment recommendations among 176 consented patients recruited from the endocrinology out-patient clinics of two teaching hospitals in southwestern Nigeria between November, 2010 and January, 2011.

Results

Overlaps of non-adherence behavior were obtained. More than three-quarter (153; 88.4%) were not aware of indication for each of the prescribed medications, 26 (15.3%) correctly described regimen as prescribed. The factorsidentified as possible barriers to medication adherence include practical (145; 40.1%), knowledge (103; 28.5%), and attitudinal (114; 31.5%) barriers. Dietary non-adherence was mostly due to inappropriate guidance (62; 33.7%).

Conclusions

The arrays of non-adherence behavior among the cohort further emphasize the need for patient-centered approach as a reasonable strategy in resolving non-adherence problems in routine clinical practice.     

Cost-effectiveness of point-of-care C-reactive protein testing to inform antibiotic prescribing decisions

Background

Point-of-care C-reactive protein (POCCRP) is a biomarker of inflammation that offers clinicians a rapid POC test to guide antibiotic prescribing decisions for acute cough and lower respiratory tract infections (LRTI). However, evidence that POCCRP is cost-effective is limited, particularly outside experimental settings.

Aim

To assess the cost-effectiveness of POCCRP as a diagnostic tool for acute cough and LRTI from the perspective of the health service.

Design and setting

Observational study of the presentation, management, and outcomes of patients with acute cough and LRTI in primary care settings in Norway and Sweden.

Method

Using hierarchical regression, data were analysed in terms of the effect on antibiotic use, cost, and patient outcomes (symptom severity after 7 and 14 days, time to recovery, and EQ-5D), while controlling for patient characteristics (self-reported symptom severity, comorbidities, and health-related quality of life) at first attendance.

Results

POCCRP testing is associated with non-significant positive reductions in antibiotic prescribing (P = 0.078) and increased cost (P = 0.092). Despite the uncertainty, POCCRP testing is also associated with a cost per quality-adjusted life year (QALY) gain of €9391. At a willingness-to-pay threshold of €30 000 per QALY gained, there is a 70% probability of CRP being cost-effective.

Conclusion

POCCRP testing is likely to provide a cost-effective diagnostic intervention both in terms of reducing antibiotic prescribing and in terms of QALYs gained.     

Association between point-of-care CRP testing and antibiotic prescribing in respiratory tract infections: a systematic review and meta-analysis of primary care studies

Background

Most patients with respiratory tract infections (RTIs) are prescribed antibiotics in general practice. However, there is little evidence that antibiotics bring any value to the treatment of most RTIs. Point-of-care C-reactive protein testing may reduce antibiotic prescribing.

Aim

To systematically review studies that have examined the association between point-of-care (POC) C-reactive protein testing and antibiotic prescribing for RTIs in general practice.

Design and setting

Systematic review and meta-analysis of randomised controlled trials and observational studies.

Method

MEDLINE^® and Embase were systematically searched to identify relevant publications. All studies that examined the association between POC C-reactive protein testing and antibiotic prescribing for patients with RTIs were included. Two authors independently screened the search results and extracted data from eligible studies. Dichotomous measures of outcomes were combined using risk ratios (RRs) with 95% confidence intervals (CIs) either by fixed or random-effect models.

Results

Thirteen studies containing 10 005 patients met the inclusion criteria. POC C-reactive protein testing was associated with a significant reduction in antibiotic prescribing at the index consultation (RR 0.75, 95% CI = 0.67 to 0.83), but was not associated with antibiotic prescribing at any time during the 28-day follow-up period (RR 0.85, 95% CI = 0.70 to 1.01) or with patient satisfaction (RR 1.07, 95% CI = 0.98 to 1.17).

Conclusion

POC C-reactive protein testing significantly reduced antibiotic prescribing at the index consultation for patients with RTIs. Further studies are needed to analyse the confounders that lead to the heterogeneity.     

Amoxicillin for acute lower respiratory tract infection in primary care: subgroup analysis of potential high-risk groups

Background

Antibiotics are of limited overall clinical benefit for uncomplicated lower respiratory tract infection (LRTI) but there is uncertainty about their effectiveness for patients with features associated with higher levels of antibiotic prescribing.

Aim

To estimate the benefits and harms of antibiotics for acute LRTI among those producing coloured sputum, smokers, those with fever or prior comorbidities, and longer duration of prior illness.

Design and setting

Secondary analysis of a randomised controlled trial of antibiotic placebo for acute LRTI in primary care.

Method

Two thousand and sixty-one adults with acute LRTI, where pneumonia was not suspected clinically, were given amoxicillin or matching placebo. The duration of symptoms, rated moderately bad or worse (primary outcome), symptom severity on days 2–4 (0–6 scale), and the development of new or worsening symptoms were analysed in pre-specified subgroups of interest. Evidence of differential treatment effectiveness was assessed in prespecified subgroups by interaction terms.

Results

No subgroups were identified that were significantly more likely to benefit from antibiotics in terms of symptom duration or the development of new or worsening symptoms. Those with a history of significant comorbidities experienced a significantly greater reduction in symptom severity between days 2 and 4 (interaction term −0.28, P = 0.003; estimated effect of antibiotics among those with a past history −0.28 [95% confidence interval = −0.44 to −0.11], P = 0.001), equivalent to three people in 10 rating symptoms as a slight rather than a moderately bad problem. For subgroups not specified in advance antibiotics provided a modest reduction in symptom severity for non-smokers and for those with short prior illness duration (<7 days), and a modest reduction in symptom duration for those with short prior illness duration.

Conclusion

There is no clear evidence of clinically meaningful benefit from antibiotics in the studied high-risk groups of patients presenting in general practice with uncomplicated LRTIs where prescribing is highest. Any possible benefit must be balanced against the side-effects and longer-term effects on antibiotic resistance.     

Euthanasia in patients dying at home in Belgium: interview study on adherence to legal safeguards

Background

Euthanasia became legal in Belgium in 2002. Physicians must adhere to legal due care requirements when performing euthanasia; for example, consulting a second physician and reporting each euthanasia case to the Federal Review Committee.

Aim

To study the adherence and non-adherence of GPs to legal due care requirements for euthanasia among patients dying at home in Belgium and to explore possible reasons for non-adherence.

Design of study

Large scale, retrospective study.

Setting

General practice in Belgium.

Method

A retrospective mortality study was performed in 2005–2006 using the nationwide Belgian Sentinel Network of General Practitioners. Each week GPs reported medical end-of-life decisions taken in all non-sudden deaths of patients in their practice. GP interviews were conducted for each euthanasia case occurring at home.

Results

Interviews were conducted for nine of the 11 identified euthanasia cases. Requirements concerning the patient''s medical condition were met in all cases. Procedural requirements such as consultation of a second physician were sometimes ignored. Euthanasia cases were least often reported (n = 4) when the physician did not regard the decision as euthanasia, when only opioids were used to perform euthanasia, or when no second physician was consulted. Factors that may contribute to explaining non-adherence to the euthanasia law included: being unaware of which practices are considered to be euthanasia; insufficient knowledge of the euthanasia law; and the fact that certain procedures are deemed burdensome.

Conclusion

Substantive legal due care requirements for euthanasia concerning the patient''s request for euthanasia and medical situation were almost always met by GPs in euthanasia cases. Procedural consultation and reporting requirements were not always met.     

Antibiotic prescribing for the future: exploring the attitudes of trainees in general practice

Background

Antibiotic resistance is a public health concern worldwide. A high proportion of antibiotics are prescribed in primary care, often for conditions where there is no evidence of benefit. Without a change in these prescribing patterns, resistance will persist as a significant problem in the future. Little is known about how trainees in general practice perceive and develop their prescribing.

Aim

To explore the attitudes of trainees in general practice towards antibiotic use and resistance, and the perceived influences on their prescribing.

Design and setting

A qualitative study of 17 vocational trainees in general practice (GP registrars) in both rural and urban areas in Australia employing semi-structured interviews and a focus group.

Method

Maximum variation purposive sampling of GP registrars from diverse backgrounds and training stages continued until thematic saturation was achieved. Topics of discussion included awareness of antibiotic resistance, use of evidence-based guidelines, and perceived influences on prescribing. Transcribed interviews were coded independently by two researchers. Data collection and analysis were concurrent and cumulative, using a process of iterative thematic analysis.

Results

Registrars were aware of the importance of evidence-based antibiotic prescribing and the impact of their decisions on resistance. Many expressed a sense of dissonance between their knowledge and behaviours. Contextual influences on their decisions included patient and system factors, diagnostic uncertainty, transitioning from hospital medicine, and the habits of, and relationship with, their supervisor.

Conclusion

Understanding how trainees in general practice perceive and develop antibiotic prescribing habits will enable targeted educational interventions to be designed and implemented at a crucial stage in training, working towards ensuring appropriate antibiotic prescribing in the future.
