Pilot study assessing the direct medical cost of treating patients with cancer in Kenya; findings and implications for the future

BACKGROUND

Currently the majority of cancer deaths occur in low- and middle-income countries, where there are appreciable funding concerns. In Kenya, most patients currently pay out of pocket for treatment, and those who are insured are generally not covered for the full costs of treatment. This places a considerable burden on households if family members develop cancer. However, the actual cost of cancer treatment in Kenya is unknown. Such an analysis is essential to better allocate resources as Kenya strives towards universal healthcare.

OBJECTIVES

To evaluate the economic burden of treating cancer patients.

METHOD

Descriptive cross-sectional cost of illness study in the leading teaching and referral hospital in Kenya, with data collected from the hospital files of sampled adult patients for treatment during 2016.

RESULTS

In total, 412 patient files were reviewed, of which 63.4% (n = 261) were female and 36.6% (n = 151) male. The cost of cancer care is highly dependent on the modality. Most reviewed patients had surgery, chemotherapy and palliative care. The cost of cancer therapy varied with the type of cancer. Patients on chemotherapy alone cost an average of KES 138,207 (USD 1364.3); while those treated with surgery cost an average of KES 128,207 (1265.6), and those on radiotherapy KES 119,036 (1175.1). Some patients had a combination of all three, costing, on average, KES 333,462 (3291.8) per patient during the year.

CONCLUSION

The cost of cancer treatment in Kenya depends on the type of cancer, the modality, cost of medicines and the type of inpatient admission. The greatest contributors are currently the cost of medicines and inpatient admissions. This pilot study can inform future initiatives among the government as well as private and public insurance companies to increase available resources, and better allocate available resources, to more effectively treat patients with cancer in Kenya. The authors will be monitoring developments and conducting further research.

Validity of World Health Organisation prescribing indicators in Namibia’s primary healthcare: findings and implications

Objective

World Health Organization/International Network of Rational use of Drugs (WHO/INRUD) indicators are widely used to assess medicine use. However, there is limited evidence on their validity in Namibia’s primary health care (PHC) to assess the quality of prescribing. Consequently, our aim was to address this.

Design, setting, participants and interventions

An analytical cross-sectional survey design was used to examine and validate WHO/INRUD indicators in out-patient units of two PHC facilities and one hospital in Namibia from 1 February 2015 to 31 July 2015. The validity of the indicators was determined using two-by-two tables against compliance to the Namibian standard treatment guidelines (NSTG). The receiver operator characteristics for the WHO/INRUD indicators were plotted to determine their accuracy as predictors of compliance to agreed standards. A multivariate logistic model was constructed to independently determine the prediction of each indicator.

Main outcomes and results

Out of 1243 prescriptions; compliance to NSTG prescribing in ambulatory care was sub-optimal (target was >80%). Three of the four WHO/INRUD indicators did not meet Namibian or WHO targets: antibiotic prescribing, average number of medicines per prescription and generic prescribing. The majority of the indicators had low sensitivity and/or specificity. All WHO/INRUD indicators had poor accuracy in predicting rational prescribing. The antibiotic prescribing indicator was the only covariate that was a significant independent risk factor for compliance to NSTGs.

Conclusion

WHO/INRUD indicators showed poor accuracy in assessing prescribing practices in ambulatory care in Namibia. There is need for appropriate models and/or criteria to optimize medicine use in ambulatory care in the future.

Evaluation of antihypertensive adherence and its determinants at primary healthcare facilities in rural South Africa

Aim: To evaluate adherence to antihypertensive treatment in rural South Africa and identify potential determinants given concerns with adherence and its impact in this priority disease area. Patients & methods: Face-to-face interviews with hypertensive patients and rating their adherence to treatment using defined categorized responses. Associations between adherence and patient characteristics assessed and sensitivity analyses performed. Results: 54.6% of patients were adherent to treatment. Controlled blood pressure (BP; odds ratios [OR] = 2.1; 95% CI: 1.1, 3.8; p = 0.019), comorbidity (OR = 2.0; 95% CI: 1.1, 3.6; p = 0.032) and smoking (OR = 0.3; 95% CI: 0.1, 0.8; p = 0.018) were associated with adherence. Conclusion: Adherence and BP control were suboptimal, only smoking was an independent risk factor for adherence. Adherent patients were twice as likely to have controlled BP, although results were sensitive to the definition of adherence. Initiatives are in place to improve adherence, which will be monitored.

Prevalence of poststroke depression in Iranian patients: a systematic review and meta-analysis

BACKGROUND

Poststroke depression (PSD) is the most common and important neuropsychiatric consequences of stroke, which can result in longer hospital stay, compromise the effectiveness of rehabilitation, and reduce the patients' quality of life. However, Iranian studies have reported different and conflicting prevalence rates for PSD.

OBJECTIVE

The present systematic review and meta-analysis aimed to evaluate the overall prevalence of PSD in Iranian patients.

PATIENTS AND METHODS

A systematic search was conducted in 2018 for Persian or English articles on PSD, published in the Scientific Information Database (SID), MagIran, PubMed, Scopus, and Web of Science, using the following keywords: depression, depressive disorder, stroke, cerebrovascular disorder, and Iran and all of their possible combinations. Heterogeneity across the studies was evaluated using the Cochran's Q test. According to the heterogeneity results, a random effects model was used to estimate the overall prevalence of PSD. The data were analyzed using the Stata 12 software.

RESULTS

Overall, six articles with a total sample size of 641 patients were included in the analysis. The overall prevalence of PSD in Iran was 46.9% (95% CI: 30.1-63.7). In addition, the prevalence of PSD was higher in women (50.4%, 95% CI: 17.9-82.9) than in men (29.5%, 95% CI: 17.2-41.8). According to the results of univariate meta-regression, there was a significant relationship between PSD prevalence and sample size (P=0.010).

CONCLUSION

Around half of the stroke patients in Iran suffer from PSD. Given the overlap between neurological symptoms of stroke and depression, efforts should be made to quickly and accurately diagnose depression so that it can be effectively managed with minimum complications.

Emergency peripartum hysterectomy

A total of 54 166 mothers delivered at the Riyadh Armed Forces Hospital between 1990 and 1997, including 6119 (11.3%) caesarean sections. Emergency peripartum hysterectomy for obstetric haemorrhage was carried out in 16 cases (0.3/1000 deliveries). The operation followed major degrees of placenta praevia in 12 (75%) cases and atonic postpartum haemorrhage in four (25%). All patients required blood transfusion. There was one neonatal death and no maternal deaths. Although the operation was straightforward, bladder injury occurred in five (31%) cases which was repaired with no residual damage. Placenta accreta was confirmed histologically in 12 (75%) patients. In conclusion, all obstetricians should be aware of the strong association between a scarred uterus, placenta praevia and placenta accreta which can be very adherent and difficult to remove causing bleeding and necessitating hysterectomy. The operation should be performed by an experienced obstetrician before the patient's condition is extreme.

[Serologic and virologic investigations on the presence of BLV infection in a dairy herd in Syria]

237 cattle of a dairy herd in Syria were tested for anti-BLV antibody by the ELISA. 194 animals were additionally examined by the agar gel immunodiffusions test (AGID) on BLV antibodies and 100 by polymerase chain reaction (PCR) for BLV provirus. BLV specific antibodies were determined by means of AGID and ELISA at 62.9% and 69.2% of the examined animals, respectively. Using the PCR method the BLV provirus was detected in 89% of the investigated cattle. Only one ELISA seropositive animal was negative for BLV provirus. The results show the high BLV contamination of this herd and lead to the presumption of wide spread enzootic bovine leukosis in Syria. In the case of the diagnosis of BLV-infection, the PCR-technique compared to the serological tests proved to be much more sensitive. By the detection of BLV antibody, the ELISA showed a higher sensitivity than the AGID and in this way, is advisable as a method of choice for screening investigations. Restriction enzyme and sequence analysis of PCR-amplificates demonstrate that different BLV provirus variants (A, B and C) in the examined herd occur, where the variant C which a high similarity to an Australian BLV provirus isolates showed, occurred most frequently at 92.5%.

Epidemiology of multiple sclerosis in Arabs in Jordan: a comparative study between Jordanians and Palestinians

In a 2-year hospital-based study in Jordan 131 Arab multiple sclerosis patients were identified including 84 Palestinians and 36 Jordanians. Based on MS/ALS case ratio, multiple sclerosis was found to be twice as common among Palestinians than Jordanians. Other than the less marked female preponderance among Jordanian patients, the disease had the same clinical and paraclinical characteristics in both groups. It was more likely for Palestinian and Jordanian patients to originate from the northern parts of their countries, to be Rh negative and to be HLA-DR2 positive than their controls. Palestinians (patients and controls) did not show significant differences from Jordanians (patients and controls) in relation to their eye color, ABO and Rh blood groups distribution nor the HLA-DR or HLA-DQ (apart from HLA-DQ3) epitopes frequency, thus not offering any significant difference in the genetic-racial markers studies to explain the difference in the observed disease susceptibility. Previous studies demonstrated that 2 racially different populations sharing the same environment can have different risk of developing multiple sclerosis, but this study has shown that this can also be true for 2 racially similar populations sharing the same environment.

Multiple sclerosis in Arabs in Jordan

In a 2-year hospital-based study (1992 and 1993), there were 131 multiple sclerosis patients attending 2 large referral hospitals in Jordan. Based on MS/ALS case ratios an overall rate of 32.1 (95% CI 19.7-55.2) was estimated. There were 126 Arabs of whom 84 were Palestinians and 36 indigenous Jordanians. Comparison of these subgroups, which had a similar age distribution revealed that the disease was twice as frequent in Palestinians (estimated 42.0/100,000 (CI 2.8-90.8)) among Jordanians (estimated 20.0/100,000 (CI 9.5-47.2)). Clinical presentation, pattern of disease, disability and HLA association were similar to that in the disease reported in Caucasians in the West. All investigations including neurophysiology and imaging were also very similar to Western reports.

Clinical and electrophysiological studies of diphtheritic neuritis in Jordan

Eleven patients with acute diphtheritic neuritis were studied clinically and electrophysiologically. Decreased conduction velocity and increased distal motor latency were present in most patients within two weeks of the onset of neurological symptoms. Velocities later fell to approximately 45% of mean normal values. Wasting with electrophysiological evidence of denervation was present in 3 patients. Nerve conduction studies had returned to normal within 3 months in 8 patients. There was a striking dissociation between the time course of the clinical and the neurophysiological abnormalities: early in the illness, peripheral nerve conduction was normal in some patients despite the presence of severe weakness, and later, the maximum electrophysiological abnormalities were sometimes found after clinical recovery had commenced. The nature and sequence of the clinical and electrophysiological changes are in accord with the known pattern and distribution of the pathological changes in the disease.

Different B lymphocyte alloantigens associated with multiple sclerosis in Arabs and North Europeans

The frequencies of HLA and B-lymphocyte alloantigens were investigated in 32 Arab patients with clinically definite or early probable multiple sclerosis (M.S.) and compared with those found in 43 healthy Arab controls. A significant association was found between M.S. and the B-lymphocyte alloantigen, BT 102; this contrasts with previous findings of an association between the B-lymphocyte alloantigen BT 101 and M.S. in North Europeans. It is suggested that this difference is due to the involvement of different environmental agents, possibly viruses, in the pathogenesis of M.S. in these populations.
